The support assembly 400 is rotatably connected with the frame, and the support assembly 400 includes a support portion 411 . The support assembly 400 can be rotated relative to the frame, and when the support assembly 400 is rotated, the angle of the support portion 411 therein will change. When the bracket 200 moves downward to the preset position, the temporary storage part 620 can be supported by the support part 411 , and the weight of the temporary storage part 620 is no longer supported by the standby part 610 , so that it is no longer supported by the bearing located under the standby part 610 . The support member 210 supports. At this time, if the bracket 200 continues to move downward, the standby part 610 will move downward synchronously with the bracket 200 , thereby separating from the temporary storage part 620 (the position shown in FIG. 5 ).

In the above-mentioned embodiment, when the bracket 200 is driven by the drive assembly to carry the standby part 610 and the temporary storage part 620 stacked above the standby part 610 and moves downward to the preset position, the support part 411 in the support assembly 400 It has been rotated enough to support the temporary storage member 620 . When the support part 411 supports the temporary storage part 620 , if the support part 210 in the bracket 200 supports the standby part 610 to continue to move downward, the temporary storage part 620 is supported by the support part 411 and separated from the standby part 610 . In this device, when the support part 411 supports the temporary storage part 620, the bracket 200 is driven to move downward by the driving component, so that the separation of the standby part 610 and the temporary storage part 620 can be realized. During the whole separation process, only the support The assembly 400 rotates relative to the rack, and the drive assembly drives the bracket 200 to move downward, without the need for an external mechanical arm, so there is no need to reserve too much space for it, which is beneficial to reduce the occupied space of the entire device and make the entire device The structure is more compact, and the structure of the device is relatively simple, which can reduce the manufacturing cost to a certain extent.

Specifically, in some embodiments, the rack includes components such as a column 110 , a base 120 and a top base 130 , the bottom end of the column 110 is fixed on the base 120 , the driving component is fixedly installed on the top base 130 , and the support component 400 is fixed on the top base 130 . on the base 120. In addition to the above components, the rack also includes some other components not shown in the drawings, and each component in the rack is directly or indirectly fixedly connected.

Referring to FIGS. 1 to 3 , preferably, in some embodiments, the bracket 200 further includes a resisting member 240 connected with the supporting member 210 . When the bracket 200 moves downward, the resisting member 240 can abut against the support assembly 400 to rotate the support assembly 400 relative to the frame. Specifically, the bracket further includes a connecting member 220 and a protruding plate 230 , the supporting member 210 is connected with the connecting member 220 , the extending plate 230 is connected with the connecting member 220 , and the abutting member 240 is mounted on the extending plate 230 . In the embodiment shown in the drawings, the supporting member 210 is in the shape of a horizontal plate, and the connecting member 220 is in the shape of a vertical plate. Of course, other shapes that can achieve similar functions are also possible. Referring to FIGS. 3 to 5 , before the separation action starts, the abutting member 240 is located above the support assembly 400 and there is a certain distance between the two. When the bracket 200 moves downward, the abutting member 240 gradually approaches the supporting assembly 400 . And contact with the support assembly 400, with the downward movement of the bracket 200, a certain pressure will be applied to the support assembly 400, so that the support assembly 400 rotates relative to the rack. In this embodiment, as the bracket 200 moves down, the support assembly 400 can be rotated by the bracket 200 abutting against the support assembly 400. Therefore, there is no need to provide an additional driver to drive the support assembly 400 to rotate, and the entire device can be made to rotate. Fewer parts, simpler structure and lower cost.

Referring to FIGS. 1 to 3 , in some embodiments, the support assembly 400 is disposed on at least one side of the bracket 200 , the mounting member 140 is connected to the rack, the support assembly 400 is pivotally connected to the mounting member 140 , and the support assembly 400 can Rotating around the axis to gradually approach the bracket 200, when the bracket 200 moves to the preset position, the support portion 411 is horizontal. Specifically, the mounting member 140 is fixedly connected to the base 120 , and at least one side of the bracket 200 is provided with the mounting member 140 . The rotating shaft pivotally connecting the support assembly 400 and the mounting member 140 is a horizontal shaft, that is, its axis is located in a horizontal plane. When the abutting member 240 moves downward with the bracket 200 gradually, the abutting member 240 abuts against the support assembly 400, so that the support assembly 400 rotates relative to the mounting member 140 around the horizontal axis in a direction close to the bracket 200, thereby gradually approaching the bracket 200. The standby part 610 and the temporary storage part 620 supported on the bracket 200 . Of course, in other embodiments, the support assembly 400 can also rotate around the vertical axis relative to the mounting member 140 . When the bracket 200 moves to the preset position, the support portion 411 has been rotated to a horizontal shape. Compared with the state with an inclined angle, the horizontal shape can support the temporary storage member 620 more stably, so that the temporary storage member 620 is not easy to slip off. . It should be noted that, when the bracket 200 moves to the preset position, the support portion 411 just rotates to a horizontal state; or, it can also be that the support portion 411 has been rotated to a horizontal state before the bracket 200 moves to the preset position.

Preferably, in the embodiment shown in the drawings, both sides of the bracket 200 are provided with mounting members 140 , that is, both sides of the bracket 200 are provided with support assemblies 400 . Correspondingly, two ends of the connecting member 220 are connected with a protruding plate 230, each protruding plate 230 is connected with a resisting member 240, and each resisting member 240 is used for resisting a supporting component 400 at a corresponding position. . With this arrangement, the support parts 411 in the two support assemblies 400 can respectively support the temporary storage part 620 from both sides, the support stability is better, and the temporary storage part 620 is not easily dropped.

2 to 5 , in some embodiments, the support assembly 400 includes a swing rod 420 , the swing rod 420 includes a first section 421 and a second section 422 , the first section 421 is connected with the second section 422 , and the second section 422 Connected to the support portion 411, the included angle between the first segment 421 and the second segment 422 is an obtuse angle. When the bracket 200 moves downward, the abutting member 240 can abut against the swing rod 420; in the first state, the bracket 200 moves downward, and the abutting member 240 abuts against different areas of the first section 421 in turn, so that the support assembly 400 rotates; in the second state, the bracket 200 moves downward until the abutting member 240 abuts against the first section At the connection point between 421 and the second section 422, the support part 411 is horizontal, and the second section 422 is vertical; in the third state, the bracket 200 moves downward, and the abutting members 240 are pressed against each other in a vertical shape. different regions of the second segment 422 until the carriage 200 moves to the preset position.

Specifically, the support assembly 400 includes a main body member 410, a swing rod 420 and a rotating member 430. Both the swing rod 420 and the rotating member 430 are fixedly connected to the main body member 410, and the three can be integrally formed, or connected by welding, threaded fasteners, etc. In a manner of connection, the rotating member 430 is pivotally connected with the mounting member 140 . The support portion 411 is a plate-shaped member protruding outward from the main body portion of the main body member 410 , and the main body portion is also a plate-shaped member. The support portion 411 is perpendicular to the main body portion of the main body member 410 . The swing rod 420 includes a first section 421, a second section 422, and a third section 423 connected in sequence, the first section 421 is connected with the second section 422, and the second section 422 is connected with the main body 410 through the third section 423, so as to realize Connected to the support portion 411 . The resisting member 240 drives the support assembly 400 to rotate by resisting against the first segment 421 and the second segment 422 of the swing rod 420 . When the bracket 200 moves downward, the abutting member 240 gradually approaches the first section 421 until it contacts the free end of the first section 421 (ie, the end of the first section 421 away from the second section 422), thereby entering the first section 421. a state. At this time, as the bracket 200 continues to move downward, the abutting member 240 will abut against the first segment 421 , so that the first segment 421 drives the entire supporting assembly 400 to rotate toward the inside of the rack. At the same time, the position of the abutting member 240 against the first section 421 will also change, gradually transitioning from the free end of the first section 421 to the connection between the first section 421 and the second section 422, thereby entering the second state . When the abutting member 240 abuts against the connection between the first section 421 and the second section 422 , the support assembly 400 has been rotated until the support portion 411 is horizontal, and the second section 422 and the main body of the main body 410 are both vertical At this time, the support portion 411 already has the ability to support the temporary storage component 620 . Next, the third state is entered, and the resisting member 240 continues to move downward along the second segment 422 with the bracket 200 . During the movement, the resisting member 240 always resists the vertical second segment 422 . In the third state, the bracket 200 moves downward until the bracket 20 reaches a predetermined position, and the temporary storage member 620 is supported by the support portion 411 .

The side parts of the standby part 610 and the temporary storage part 620 are both provided with protruding parts 621 that protrude outward. Temporary storage component 620 supports. In the above-mentioned first state, when the support portion 411 gradually rotates in a direction close to the temporary storage member 620, the standby member 610 and the temporary storage member 620 supported by the bracket 200 move downward synchronously with the bracket 200, When the component 610 is moved to the bottom of the support portion 411 , the two temporary storage components 620 are still located above the support portion 411 . In the third state, when the bracket 200 continues to move downward, the two temporary storage components 620 also move downward synchronously. In the part 620, the protruding part 621 of the lower temporary storage part 620 is in contact with the support part 411, and the weight of the two temporary storage parts 620 is changed from being supported by the bracket 200 to being supported by the supporting part 411. At this time, the bracket 200 is only The component 610 to be used needs to be carried. After that, as the bracket 200 continues to move downward, the temporary storage member 620 will move downward synchronously, and the two temporary storage members 620 supported by the support portion 411 will be suspended above the temporary storage member 620 . The component 610 and the temporary storage component 620 are separated. The separated ready-to-use component 610 can be driven by the bracket 200 to continue to move downward, and be transported away by the transport assembly below.

It should be noted that, in order to ensure that during the downward movement of the stand-by part 610 with the bracket 200 in the first state, the protruding part on the stand-by part 610 does not interfere with the supporting part 411 in the inclined state. The size of the protruding part should not be too large. It should also be ensured that the length of the second segment 422 is greater than the vertical distance between the protruding parts provided on the standby part 610 and the temporary storage part 620, that is, the second segment 422 provides enough travel for the abutting part 240 to avoid When the resisting member 240 moves to the lower end of the second segment 422 , the temporary storage member 620 has not moved to be supported by the supporting portion 411 . In addition, the vertical distance between the support member 210 and the abutting member 240 also needs to be considered, and the distance between the two should not be too large, so as to avoid that when the abutting member 240 is moved to contact with the first section 421, in addition to the standby member 610, Some of the temporary storage components 620 have also been located below the support portion 411 , and in this case, only the standby components 610 cannot be separated. In addition, the length of the first segment 421 should be adapted to the inclination angle of the support portion 411 relative to the vertical direction in the initial state, so as to ensure that the abutting member 240 reaches the first segment 421 and the second segment 421 from the free end of the first segment 421 When the segments 422 are connected, the swing rod 420 rotates at an appropriate angle, and the support portion 411 can be rotated to be horizontal. The descending distance of the abutting member 240 from the first state to the end of the second state should be the distance between the temporary storage part 620 and the respective protruding parts 621 on the standby part 610, and the relative distance between the supporting part 411 in the initial state. The inclination angle in the vertical direction is adapted to prevent the temporary storage part 620 from failing to separate after the bracket 200 moves to the bottom of the support part 411 during the process from the first state to the second state. The settings of the above various parameters can be obtained through multiple adjustments during manufacture, and the best results can be achieved through multiple adjustments.

Preferably, in some embodiments, when the bracket 200 moves downward until the abutting member 240 abuts against different regions of the swing rod 420 , the abutting member 240 rolls along the upper surface of the swing rod 420 . Specifically, the abutting member 240 is rotatably connected to the protruding plate 230 , and this arrangement can reduce the frictional force between the abutting member 240 and the swing rod 420 and reduce the wear degree of the abutting member 240 after prolonged contact. Specifically, the abutting member 240 may directly select a roller or a bearing.

Preferably, in some embodiments, an elastic member 520 is connected between the support assembly 400 and the mounting member 140 , and the elastic member 520 is used to drive the support assembly 400 to rotate in the opposite direction relative to the mounting member 140 to reset. Specifically, the elastic member 520 may be a spring, one end of which is fixedly connected to the rotating member 430 , and the other end is fixedly connected to the mounting member 140 . When the support assembly 400 is resisted by the resisting member 240 and rotates in a direction close to the temporary storage member 620 , the elastic member 520 is in a stretched state. When the external force applied to the support assembly 400 disappears, the support assembly 400 will be reversely rotated and reset under the drive of the resilient force of the elastic member 520 . In this embodiment, by arranging the elastic member 520, the automatic reset can be realized by using it, and there is no need to manually toggle the reset, which can be more convenient.

After a single separation is completed, the lower one of the two temporary storage parts 620 becomes the spare part in the next separation. For the next separation, the bracket 200 needs to be reset first. It should be noted that the spare parts 610 previously supported by the bracket 300 and separated will be transported away by the transport assembly, that is, the bracket 200 is vacant at this time and does not support any components. By driving the bracket 200 to move upwards by the driving assembly, the abutting member 240 moves upwards along the second section 422, and gradually reaches the connection between the first section 421 and the second section 422, and then continues to move upwards. At this time, the bracket 200 has not moved to contact with the temporary storage part 620 , therefore, the temporary storage part 620 is still carried by the support part 411 . When the connection with the second segment 422 continues to move upward, the support assembly 400 will not be rotated and reset in the opposite direction, so the resisting member 240 will not be in contact with the first segment 421 at this time. When the bracket 200 moves upward to contact with the temporary storage part 620 and bear the weight of the temporary storage part 620 , the temporary storage part 620 is separated from the support part 211 , and driven by the resilient force of the elastic member 520 , the support assembly 400 will reverse Return to rotation, but to a certain extent, the first segment 421 will collide with the abutting member 240 and abut against the abutting member 240 again.
