Abstract

A tray distributing mechanism is disclosed. The tray distributing mechanism comprises a plurality of shifting pieces, a plurality of push rods, a state detection portion and a detector. Each of the plurality of push rod rotates between a horizontal position and a vertical position. When the push rod moves from a first position to a second position, the push rod touches the shifting piece, so that the shifting piece rotates from the horizontal position to the vertical position. When the push rod moves from the second position to the first position, the push rod breaks away from the shifting piece, so that the shifting piece rotates from the vertical position to the horizontal position, and holds up a loading tray. The state detecting portion maintains a preset state when an abutting part is in the horizontal position, and changes from the preset state when the abutting part is not in a horizontal position. The detector is used to detect whether the state detection unit maintains the preset state when the push rod moves from the second position to the first position.

Description

Disk Division

This case belongs to the field of multiple passenger plate separation technology, especially a plate separation mechanism.

In the production process of electronic or mechanical products, the processed products, such as chips, need to be placed in a tray for subsequent transportation and retrieval. For the convenience of transportation, multiple trays are usually stacked.

Generally speaking, in order to achieve automatic separation of multiple passenger trays, the stacked passenger trays are placed in a tray separation mechanism. When the loading or taking out of the products in a passenger tray is completed, the paddle of the tray separation mechanism is inserted into the gap between the empty passenger tray and the adjacent passenger tray to facilitate loading or taking out of the next passenger tray.

However, the traditional tray-dividing mechanism does not have a mechanism to detect whether the paddle is properly inserted into the gap between the empty tray and the adjacent tray. Therefore, when some factors cause the paddle to not be properly inserted into the gap between the empty tray and the adjacent tray, but the tray-dividing mechanism continues to operate, it will not only cause the related components in the tray-dividing mechanism to be easily damaged, but also cause damage to the tray and the products in the tray. It is more likely to cause the tray to tilt and not be in the correct position, making the tray-dividing mechanism operate abnormally, which is not conducive to automatic operation.

Therefore, how to develop a sub-market mechanism that overcomes the above shortcomings is an urgent need at present.

The purpose of this case is to provide a plate dividing mechanism to solve the problem that the traditional plate dividing mechanism does not have a mechanism to detect whether the paddle is normally inserted into the gap between the air passenger tray and the adjacent passenger tray, which causes the related components of the traditional plate dividing mechanism to be easily damaged during the plate dividing operation and easily causes the loss of products in the passenger tray.

To achieve the above-mentioned purpose, one embodiment of the present case is a plate-separating mechanism for separating a plurality of passenger plates. The plate-separating mechanism comprises: a support portion that selectively moves up and down; a plurality of paddles that are arranged at the four corners of a rectangular surface, wherein the plurality of passenger plates are supported by the support portion or by the plurality of paddles, and when the plurality of passenger plates are supported by the support portion, the support portion drives the plurality of passenger plates to move up and down, and each paddle comprises a fulcrum shaft, an inclined portion, and a top stop. The top portion is integrally formed on the inclined portion and includes a convex portion structure, which extends horizontally from the side of the top portion to the X-axis direction to support a plurality of carrier plates, the inclined portion includes an inclined surface, the fulcrum shaft is sleeved in the top portion, and the inclined portion drives the top portion to rotate between a horizontal position and a vertical position using the fulcrum shaft; a plurality of push rods, each push rod is adjacent to a corresponding paddle, and each push rod is horizontally positioned between a first position and a second position. When the push rod moves from the first position to the second position and moves to the second position, the push rod contacts the inclined surface of the inclined surface and continues to push the inclined surface, so that the inclined surface drives the top part to rotate from the horizontal position to the vertical position, and the supporting part holds up a plurality of riding plates. When the push rod moves from the second position to the first position, the push rod disengages from the inclined surface of the inclined surface, so that the inclined surface drives the top part to rotate from the vertical position to the horizontal position, so that the top part is inserted into the plurality of A gap between two of the two loading plates of the plurality of loading plates is used to perform a plate splitting action; a state detection unit, the state detection unit is maintained in a preset state when the abutting portion is in a horizontal position, and the state detection unit changes from the preset state when the abutting portion is not in a horizontal position; and a detector, which is used to detect whether the state detection unit is in the preset state when the push rod moves from the second position to the first position, and output a warning message when the state detection unit is detected to be not maintained in the preset state.

To achieve the above-mentioned purpose, another embodiment of the present invention is a tray separation mechanism for separating a plurality of passenger trays. The tray separation mechanism comprises: a support portion that selectively moves up and down; a plurality of paddles that are arranged at the four corners of a rectangular surface, wherein the plurality of passenger trays are supported by the support portion or by the plurality of paddles, and when the plurality of passenger trays are supported by the support portion, the support portion drives the plurality of passenger trays to move up and down, and each paddle contains The invention comprises a fulcrum shaft, an inclined surface and an abutting portion, wherein the abutting portion is integrally formed on the inclined surface and comprises a convex structure, wherein the convex structure horizontally extends outward from the side of the abutting portion to support a plurality of riding plates, and the inclined surface comprises an inclined surface, wherein the fulcrum shaft is sleeved in the abutting portion, and the inclined surface drives the abutting portion to rotate between a horizontal position and a vertical position by utilizing the fulcrum shaft; and a plurality of push rods, wherein each push rod is adjacent to a corresponding paddle. Each push rod reciprocates horizontally between a first position and a second position. When the push rod moves from the first position to the second position and moves to the second position, the push rod contacts the inclined surface of the inclined surface and continues to push the inclined surface, so that the inclined surface drives the top part to rotate from a horizontal position to a vertical position, and the supporting part holds up a plurality of riding plates. When the push rod moves from the second position to the first position, the push rod separates from the inclined surface of the inclined surface, so that the inclined surface drives the top part to rotate from a horizontal position to a vertical position. The movable stopper is rotated from a vertical position to a horizontal position so that the stopper is inserted into the gap between two of the plurality of passenger trays to perform a tray separation action; the photoelectric switch is disposed adjacent to the plurality of passenger trays and is used to emit a transmission light horizontally from the direction of the plurality of passenger trays, and output a warning message when the reflected light reflected by the transmission light is not received from the plurality of passenger trays or the received reflected light is incomplete.

Some typical embodiments that embody the features and advantages of this case will be described in detail in the following description. It should be understood that this case can have various variations in different forms, all of which do not deviate from the scope of this case, and the descriptions and drawings therein are essentially for illustrative purposes rather than for limiting this case.

Please refer to Figures 1 to 3, wherein Figure 1 is a schematic diagram of the structure of the plate-splitting mechanism and multiple riding plates of the first preferred embodiment of the present invention, Figure 2 is a schematic diagram of another angle of view of the plate-splitting mechanism shown in Figure 1 without the riding plates, and Figure 3 is a schematic diagram of the structure of the paddle and push rod shown in Figure 1. The plate-splitting mechanism 1 of the present invention is used to perform a plate-splitting operation on multiple riding plates 2, and includes a support portion 20, multiple paddles 21, multiple push rods 22, a state detection portion 23, and a detector 24.

The support portion 20 can be driven by a motor (not shown) to selectively move up and down, wherein the selectivity means that the support portion 20 can selectively move up or down. A plurality of paddles 21 are arranged at intervals, and the arrangement positions of the plurality of paddles 21 can form a rectangular surface, and the plurality of paddles 21 are located at the four corners of the rectangular surface. In this embodiment, a plurality of passenger trays 2 can be lifted by the support portion 20 or by the plurality of paddles 21, and when the plurality of passenger trays 2 are lifted by the support portion 20, the support portion 20 synchronously drives the plurality of passenger trays 2 to move up and down. Each paddle 21 includes a fulcrum shaft 210, an inclined portion 211, and a top portion 212. The fulcrum shaft 210 is sleeved on the abutting portion 212 , and the inclined portion 211 utilizes the fulcrum shaft 210 to drive the abutting portion 212 to rotate between a horizontal position and a vertical position. The top-butting portion 212 is integrally formed on the inclined portion 211 and includes a convex structure 213. The convex structure 213 extends horizontally from the side of the top-butting portion 212 in the X-axis direction to support a plurality of passenger trays 2. When the inclined portion 211 drives the top-butting portion 212 to be located in a horizontal position, the convex structure 213 of the top-butting portion 212 can be inserted into the bottom of the plurality of passenger trays 2 or the gap between two of the passenger trays to support all the passenger trays 2 above. When the inclined portion 211 drives the top-butting portion 212 to rotate from a horizontal position to a vertical position, the top-butting portion 212 can gradually detach from the gap between two of the plurality of passenger trays 2 and no longer support all the passenger trays 2 above. The inclined surface 211 includes an inclined surface 214.

Each push rod 22 is adjacent to a corresponding paddle 21, and each push rod 22 reciprocates horizontally between a first position and a second position. When the support portion 20 pushes the vehicle tray 2 upward to a certain distance, and the push rod 22 moves from the first position to the second position, the push rod 22 contacts the inclined surface 214 of the inclined surface 211, so that the inclined surface 211 drives the abutting portion 212 to rotate from a horizontal position to a vertical position, thereby allowing the convex structure 213 of the abutting portion 212 to gradually withdraw from the gap between two of the plurality of vehicle trays 2. When the push rod 22 moves to the second position, the inclined surface 214 drives the abutting portion 212 to move to a vertical position, and at this time, the plurality of vehicle trays 2 are completely lifted by the support portion 20. When the push rod 22 moves from the second position to the first position, the push rod 22 separates from the inclined surface 214 of the inclined surface 211 and does not contact the inclined surface 214. The inclined surface 211 will drive the top portion 212 to rotate from the vertical position to the horizontal position due to a reset element (not shown), such as a spring, so that the convex structure 213 of the top portion 212 is inserted into the gap between two of the multiple riding trays 2 to perform the tray separation action.

The state detection unit 23 is maintained in a preset state when the abutting portion 212 is in a horizontal position, and the state detection unit 23 changes from the preset state when the abutting portion 212 is not in a horizontal position.

The detector 24 is used to detect whether the state detection unit 23 is maintained in the preset state when the push rod 22 moves from the second position to the first position, and output a warning message when it is detected that the state detection unit 23 is not maintained in the preset state.

As can be seen from the above, the plate splitting mechanism 1 of the present case is provided with the state detection unit 23 and the detector 24, wherein the state detection unit 23 is maintained in a preset state when the abutting portion 212 is in a horizontal position, and when the abutting portion 212 is not in a horizontal position, the state detection unit 23 changes from the preset state, and the detector 24 can detect the state when the push rod 22 moves from the second position to the first position. The state detection unit 23 is maintained in the preset state, and a warning message is outputted when the state detection unit 23 is not maintained in the preset state. The tray-dividing mechanism 1 of the present case has a mechanism for detecting whether the paddle 21 is normally inserted into the gap between the air passenger tray 2 and the adjacent passenger tray 2, thereby avoiding damage to the related components in the tray-dividing mechanism 1 and the products in the passenger tray 2.

Please refer to Figures 4A and 4B, where Figures 4A and 4B are partial structural operation schematic diagrams of the disc separation mechanism when the state detection portion is a vacuum generator. In some embodiments, the state detection portion 23 is a vacuum generator. When the top portion 212 is in a horizontal position, the paddle 21 will partially block the air hole used for detection by the state detection portion 23, so that the state detection portion 23 forms a maximum negative pressure (as shown in Figure 4A). The maximum negative pressure is the preset state described above. When the top portion 212 moves from a horizontal position to a vertical position instead of being in a horizontal position, the air hole used for detection by the state detection portion 23 is no longer blocked by the paddle 21 and remains smooth. At this time, the state detection portion 23 forms a minimum negative pressure (as shown in Figure 4B). In addition, the detector 24 is a pressure detector, which is used to detect whether the state detection unit 23 is at the maximum negative pressure when the push rod 22 moves from the second position to the first position, and output a warning message when it is detected that the state detection unit 23 is not at the maximum negative pressure.

In some embodiments, the tray-dividing mechanism 1 further includes a main board 25, and the main board 25 has a plurality of through holes 250 for part of the supporting part 20 to pass through, so that the supporting part 20 can move up and down. In addition, the tray-dividing mechanism 1 further includes a plurality of tray-dividing guide rails 26, such as the four shown in FIG. 1, and the plurality of tray-dividing guide rails 26 are arranged on the main board 25 in a staggered manner, and the passenger tray 2 can be arranged in the tray-dividing mechanism 1 through the tray-dividing guide rails 26, and can move up and down through the guide groove structure in the tray-dividing guide rails 26.

Please refer to FIG. 5A and FIG. 5B, where FIG. 5A and FIG. 5B are partial structural operation schematic diagrams of the split disk mechanism when the state detection portion is a micro switch. Of course, in other embodiments, such as FIG. 5A and FIG. 5B, the state detection portion 23 can be changed to a micro switch. When the top portion 212 is in a horizontal position, the paddle 21 will partially press the micro switch, so that the micro switch is in a closed state (as shown in FIG. 5A), and the closed state is the default state described above. When the top portion 212 moves from a horizontal position to a vertical position instead of being in a horizontal position, the micro switch is no longer pressed by the paddle 21 and pops up to present a conductive state (as shown in FIG. 5B). The state detection unit 23 is used to detect whether the micro switch of the state detection unit 23 is in the closed state when the push rod 22 moves from the second position to the first position, and output a warning message when it is detected that the state detection unit 23 is not in the closed state.

Please refer to Figures 6A to 6D, and in conjunction with Figure 1, Figures 6A to 6D are schematic diagrams of the operation of the plate separation mechanism shown in Figure 1. First, as shown in Figure 6A, the plurality of paddles 21 are in a horizontal position and jointly support the plurality of passenger trays 2. At this time, the support portion 20 is a distance away from the plurality of passenger trays 2 and does not support the plurality of passenger trays 2.

Next, when the plate splitting action is to be performed, as shown in FIG. 6B , the support portion 20 is driven by the motor to move upward to contact the bottommost plate 2 among the plurality of plates 2 and to push the plate 2 upward to a certain distance. At the same time, each push rod 22 moves from the first position to the second position, so that the paddle 21 is lifted up, thereby allowing the convex structure 213 of the abutting portion 212 to gradually withdraw from the gap between two of the plurality of plates 2. The plurality of plates 2 are also lifted by the support portion 20. At the same time, the detector 24 starts to detect whether the state detection portion 23 is maintained in the preset state.

Then, as shown in FIG. 6C , the support portion 20 is driven by the motor to move downward, and at the same time, each push rod 22 moves from the second position to the first position to drive the top portion 212 to rotate from the vertical position to the horizontal position, so that the convex structure 213 of the top portion 212 is inserted into the gap between two of the plurality of riding plates 2 to perform the plate separation action.

Finally, as shown in FIG. 6D , the support portion 20 is driven by the motor to continue to move downward. If the abutting portion 212 can rotate normally to the horizontal position, one of the plurality of carrier plates 2 will be separated, and the convex structure 213 of the abutting portion 212 will hold up the remaining carrier plates 2. On the contrary, if the abutting portion 212 cannot rotate normally to the horizontal position, the detector 24 will detect that the state detection portion 23 is not maintained in the preset state and output a warning message. The separating mechanism 1 can take protective measures according to the warning message, such as stopping operation.

Please refer to Figures 7, 8 and 9, wherein Figure 7 is a schematic diagram of the structure of the plate-splitting mechanism and a plurality of carrier plates of the second preferred embodiment of the present invention, Figure 8 is a schematic diagram of another viewing angle of the plate-splitting mechanism shown in Figure 7 without the carrier plates, and Figure 9 is a schematic diagram of the structure of the carrier plates and the photoelectric switch shown in Figure 7. The plate-splitting mechanism 1a of this embodiment is similar in structure to the plate-splitting mechanism 1 shown in Figure 1, so the same symbols are used to indicate that the structures and functions of the components are similar and no further description is given. However, the tray-dividing mechanism 1a of this embodiment does not have the state detection unit 23, and the detector 24a of the tray-dividing mechanism 1a includes a photoelectric switch instead, wherein the photoelectric switch uses the projection and reflection of light for detection, that is, the detector 24a projects light horizontally toward the direction of the loading tray 2 on the support 20. The light projected by the detector 24a toward the loading tray 2 will be completely reflected by the loading tray 2, so the detector 24a receives the completely reflected light without issuing a warning message. On the contrary, when the paddle 21 is not normally inserted into the gap between the passenger tray 2 and the adjacent passenger tray 2, causing the passenger tray 2 on the support portion 20 to tilt, the light projected by the detector 24a toward the passenger tray 2 will not be reflected by the passenger tray 2 or will not be completely reflected to the detector 24a due to incomplete shielding. This means that the paddle 21 is not normally inserted into the gap between the passenger tray 2 and the adjacent passenger tray 2, so the detector 24a issues a warning message.

In some embodiments, the detector 24a is adjacent to the bottommost platform 2, for example, adjacent to the lower edge of the bottommost platform 2.

In summary, the present invention provides a plate splitting mechanism, wherein the plate splitting mechanism of the first embodiment is provided with a state detection unit and a detector, wherein the state detection unit is maintained in a preset state when the abutting portion is in a horizontal position, and when the abutting portion is not in a horizontal position, the state detection unit changes from the preset state, and the detector can detect whether the state detection unit is maintained in the preset state when the push rod moves from the second position to the first position, and output a warning message when it is detected that the state detection unit is not maintained in the preset state. The second embodiment uses a photoelectric switch to detect whether the paddle is normally inserted into the gap between the air passenger tray and the adjacent passenger tray. The tray-dividing mechanism of this case has a mechanism to detect whether the paddle is normally inserted into the gap between the air passenger tray and the adjacent passenger tray, thereby avoiding damage to related components in the tray-dividing mechanism and products in the passenger tray.
