Description

Platen Cleanliness Detection Device

The present invention relates to a detection device, and more particularly to a carrier cleanliness detection device.

In recent years, the use of semiconductor chips has increased significantly. Due to the high precision of semiconductor chip processing, two-piece carriers are required to secure the chips during processing and to clean the carriers after processing. However, this cleaning process is often performed manually, which is not only labor-intensive and time-consuming, but also has the potential to damage the carriers due to poor rinsing angles.

Clearly, researchers in related fields urgently need to develop an automated platen cleanliness inspection device to reduce current overall costs and further avoid damage caused by poor rinsing angles.

Therefore, an object of the present invention is to provide a carrier cleanliness detection device that can reduce cleaning costs.

Therefore, the present invention provides a pallet cleaning and inspection device suitable for cleaning and inspecting a pallet. The pallet comprises a lower plate defining a plurality of lower plate holes, and an upper plate aligned with the lower plate and defining a plurality of upper plate holes. The pallet cleaning and inspection device includes a frame, a conveying unit, a pallet separation unit, a cleaning unit, an inspection unit, a sorting unit, and a control unit. The conveying unit is mounted on the frame and defines a conveying direction. The conveying unit includes a pallet separation conveyor assembly, a cleaning conveyor assembly adjacent to the pallet separation conveyor assembly, an inspection conveyor assembly adjacent to the cleaning conveyor assembly, a sorting conveyor assembly, and a defective product conveyor assembly. The panel separation unit is positioned corresponding to the panel separation and conveying assembly and includes a lower drive assembly mounted on the frame, a lift base on which the lower drive assembly is movably mounted in a vertical direction, an upper drive assembly mounted on the frame and located above the lift base, and a panel separation module on which the upper drive assembly is movably mounted in the vertical direction and located above the lift base. The lift base and the panel separation module are used to jointly separate the lower panel from the upper panel, and the panel separation module is used to limit the upper panel so that the lower panel and the upper panel are spaced apart along the conveying direction. The cleaning unit is positioned corresponding to the cleaning and conveying assembly and is used to clean the lower panel and the upper panel. The inspection unit is located in correspondence with the inspection and conveying group and is used to inspect and obtain the lower plate size information corresponding to the lower plate and the upper plate size information corresponding to the upper plate. The picking unit is located in correspondence with the picking and conveying group and the defective product conveying group and is used to move the lower plate and the upper plate to the picking and conveying group or the defective product conveying group. The control unit is electrically connected to the detection unit and the selection unit. The control unit stores a lower plate preset size information, an upper plate preset size information, a lower plate deformation threshold and an upper plate deformation threshold. If the control unit receives the lower plate size information from the detection unit, and the deformation of the lower plate size information relative to the lower plate preset size information is greater than the lower plate deformation threshold, the control unit controls the selection unit to move the lower plate body to the defective product conveying group. If the control unit receives the upper plate size information from the detection unit, and the deformation of the upper plate size information relative to the upper plate preset size information is greater than the upper plate deformation threshold, the control unit controls the selection unit to move the upper plate body to the defective product conveying group.

Therefore, the pallet cleaning and inspection device of the present invention includes a frame, a conveying unit, a pallet, a panel separation unit, a cleaning unit, a detection unit, a sorting unit, and a control unit. The conveying unit is mounted on the frame and defines a conveying direction. The conveying unit includes a panel separation conveyor assembly, a cleaning conveyor assembly adjacent to the panel separation conveyor assembly, an inspection conveyor assembly adjacent to the cleaning conveyor assembly, a sorting conveyor assembly, and a defective product conveyor assembly. The pallet includes a lower plate defining a plurality of lower plate holes and an upper plate defining a plurality of upper plate holes. The lower plate and the upper plate are magnetically attracted to each other and aligned with each other, and are configured to be moved by the conveying unit. The panel separation unit is positioned corresponding to the panel separation and conveying assembly and includes a lower drive assembly mounted on the frame, a lift base on which the lower drive assembly is movably mounted in a vertical direction, an upper drive assembly mounted on the frame and located above the lift base, and a panel separation module on which the upper drive assembly is movably mounted in the vertical direction and located above the lift base. The lift base and the panel separation module are used to jointly separate the lower panel from the upper panel, and the panel separation module is used to limit the upper panel so that the lower panel and the upper panel are spaced apart along the conveying direction. The cleaning unit is positioned corresponding to the cleaning and conveying assembly and is used to clean the lower panel and the upper panel. The inspection unit is located in correspondence with the inspection and conveying group and is used to inspect and obtain the lower plate size information corresponding to the lower plate and the upper plate size information corresponding to the upper plate. The picking unit is located in correspondence with the picking and conveying group and the defective product conveying group and is used to move the lower plate and the upper plate to the picking and conveying group or the defective product conveying group. The control unit is electrically connected to the detection unit and the selection unit. The control unit stores a lower plate preset size information, an upper plate preset size information, a lower plate deformation threshold and an upper plate deformation threshold. If the control unit receives the lower plate size information from the detection unit, and the deformation of the lower plate size information relative to the lower plate preset size information is greater than the lower plate deformation threshold, the control unit controls the selection unit to move the lower plate body to the defective product conveying group. If the control unit receives the upper plate size information from the detection unit, and the deformation of the upper plate size information relative to the upper plate preset size information is greater than the upper plate deformation threshold, the control unit controls the selection unit to move the upper plate body to the defective product conveying group.

The effectiveness of the present invention is that by providing the conveying unit, the plate separation unit, the cleaning unit and the detection unit, the lower plate and the upper plate are spaced apart along the conveying direction, so that the cleaning unit can clean the lower plate and the upper plate separately, and the detection unit can detect the lower plate and the upper plate separately, thereby improving the cleanliness of the carrier and the detection accuracy.

4 to 6 , the cleaning unit 4 is located corresponding to the cleaning conveying assembly 22 and is used to clean the lower plate 110 and the upper plate 120 . The cleaning unit 4 includes a cleaning housing 41 defining a rinsing space 411 and a drying space 412, a rinsing module 42 located in the rinsing space 411, and a drying module 43 located in the drying space 412.

In other variations of this embodiment, the number of laser elements of the laser sensor 64 can also be reduced to one to three according to the current measurement accuracy requirements (such as when the measurement accuracy requirements are not high), and is not limited to this embodiment.

The detection unit 6 is used to scan one of the lower plate tag 112 and the upper plate tag 122 according to the RFID reader 65 to obtain relevant information of the scanned object (such as model, size, etc.), and obtain lower plate size information corresponding to the lower plate 110 and upper plate size information corresponding to the upper plate 120 according to the detection of the laser sensor 64.

[Split board stage]

During actual operation, referring to Figures 1, 4 and 7, when the lower plate 110 and the upper plate 120 in a combined state are placed in the panel conveying group 21 of the conveying unit 2, the panel conveying group 21 of the conveying unit 2 will drive the lower plate 110 and the upper plate 120 to the position corresponding to the panel conveying unit 3 and stop operating. Then, the ejector pins 322 of the lift base 32 move upward, and the small outer diameter sections 324 of the ejector pins 322 pass through the lower plate holes 111 of the lower plate body 110 and the upper plate holes 121 of the upper plate body 120, respectively, so that the large outer diameter sections 323 of the ejector pins 322 abut against the small outer diameter sections 324 of the ejector pins 322, thereby pushing the carrier 100 away from the plate delivery assembly 21. Next, the panel separation pressing seat 341 of the panel separation module 34 moves downward and presses against the lower plate 110, thereby restraining the lower plate holes 111 of the lower plate 110 by the large outer diameter sections 323 of the ejector pins 322 and moving them to the surface of the lift plate 321. Simultaneously, the panel separation suction members 342 of the panel separation module 34 perform vacuum suction on the upper plate 120, thereby attaching the panel separation suction members 342 to the upper plate 120. Finally, the panel pressing seat 341 of the panel splitting module 34 moves upward, the top pin portion 322 of the lifting seat 32 moves downward, the lower plate body 110 and the upper plate body 120 are spaced apart along the vertical direction D3, and the lower plate body 110 returns to abut the panel splitting conveying assembly 21. At the same time, the panel separation conveying group 21 starts to operate again, driving the lower plate body 110 to continue to move a preset distance along the conveying direction D1, and the panel separation module 34 moves downward and approaches the panel separation conveying group 21. The panel separation adsorption parts 342 stop vacuum adsorption on the upper plate body 120, and the upper plate body 120 abuts against the panel separation conveying group 21, thereby separating the lower plate body 110 and the upper plate body 120 along the conveying direction D1, thereby achieving the effect of separating the lower plate body 110 and the upper plate body 120.

It is worth mentioning that if the carrier 100 is not in a combined state, that is, the lower plate 110 and the upper plate 120 are separated from each other in advance, the light interrupter 29 located in the panel conveying group 21 in the conveying unit 2 will send an unblocked signal to the control unit 9, indicating that the carrier 100 is not higher than the preset height of the light interrupter 29 located in the panel conveying group 21, and the control unit 9 does not need to control the panel unit 3 to separate the lower plate 110 and the upper plate 120.

[Cleaning phase]

Referring to Figures 4 to 6 , the cleaning conveyor assembly 22 of the conveyor unit 2 continuously drives the separated lower plate 110 and upper plate 120 to a position corresponding to the cleaning unit 4 (i.e., within the cleaning housing 41). While in the flushing space 411, the flushing nozzles 421 of the flushing module 42 rinse the lower plate 110 and upper plate 120 with pure water, while the brush rollers 422 roll and contact the moving lower plate 110 and upper plate 120, thereby achieving a flushing effect. In the drying space 412, the drying nozzles 431 blow dry air to the lower plate 110 and the upper plate 120, thereby achieving a drying effect. For simplicity, FIG6 only depicts the lower plate 110 as an example.

[Switching phase]

Referring to Figures 4 and 8 , the reversing conveyor assembly 23 of the conveyor unit 2 sequentially drives the separated and cleaned lower plate 110 and upper plate 120 to positions corresponding to the reversing unit 5 . The selecting clamping member 84 of the reversing unit 5 sequentially and individually clamps the lower plate 110 and upper plate 120 from the reversing conveyor assembly 23 to the inspection conveyor assembly 24 . Since the lower plate 110 and the upper plate 120 enter this embodiment from the plate separation conveyor assembly 21, the reversing unit 5 is able to reverse the movement of the cleaned lower plate 110 and the upper plate 120, making it convenient to recover the lower plate 110 and the upper plate 120 from the selection conveyor assembly 26 adjacent to the plate separation conveyor assembly 21. For the sake of simplicity, FIG8 only depicts the lower plate 110 as an example.

[Detection phase]

Referring to Figures 1, 4, and 9, the inspection and conveyor assembly 24 of the conveyor unit 2 sequentially drives the separated lower plate 110 and upper plate 120 to a position corresponding to the inspection unit 6. The inspection unit 6 scans one of the lower plate tag 112 and the upper plate tag 122 using the RFID reader 65 to obtain information related to the scanned object (such as model, size, etc.) and determine that the scanned object is the lower plate 110 or the upper plate 120. Then, the laser sensor 64 starts to perform a three-dimensional measurement operation on the currently scanned object and build a model, correspondingly obtaining the lower plate size information or the upper plate size information, and correspondingly transmitting the lower plate size information or the upper plate size information to the control unit 9.

[Plywood and Selection Stage]

Referring to Figures 1, 4 and 10, since in practice, the lower plate 110 and the upper plate 120 are designed as a group (both belong to the carrier 100), the lower plate 110 and the upper plate 120 will be restored to a combined state, that is, the upper plate 120 will be adsorbed and limited by the composite plate adsorption members 74, so that the upper plate 120 is covered on the lower plate 110. If the control unit 9 receives the lower plate size information from the detection unit 6, and the deformation of the lower plate size information relative to the lower plate preset size information is greater than the lower plate deformation threshold, or if the control unit 9 receives the upper plate size information from the detection unit 6, and the deformation of the upper plate size information relative to the upper plate preset size information is greater than the upper plate deformation threshold, the control unit 9 controls the picking unit 8 to move the lower plate body 110 and the upper plate body 120 together to the defective product conveying group 27.

Conversely, if the deformation of the lower plate dimensional information relative to the preset lower plate dimensional information is less than or equal to the lower plate deformation threshold, and the deformation of the upper plate dimensional information relative to the preset upper plate dimensional information is less than or equal to the upper plate deformation threshold, the lower plate 110 and the upper plate 120 are smoothly conveyed to the selection and conveying assembly 26, completing the cleaning and inspection process. For simplicity, Figure 10 only depicts the lower plate 110 as an example.

In other words, the control unit 9 determines whether the lower plate 110 and the upper plate 120 are deformed or damaged by comparing whether the deformation of the lower plate size information relative to the lower plate preset size information is greater than the preset lower plate deformation threshold, and whether the deformation of the upper plate size information relative to the upper plate preset size information is greater than the preset upper plate deformation threshold. Therefore, in a variation of the present embodiment, even if the lower plate 110 or the upper plate 120 has structures such as pins and pads, the control unit 9 and the detection unit 6 can be used to determine whether the pins and pads are deformed or damaged, and the scope of application will not be limited by the appearance or structure of the carrier 100 of the present embodiment.

In summary, this embodiment has the following effects:

(1) By disposing the conveying unit 2, the panel separation unit 3, the cleaning unit 4 and the detection unit 6, the lower plate 110 and the upper plate 120 are spaced apart along the conveying direction D1, so that the cleaning unit 4 can clean the lower plate 110 and the upper plate 120 respectively, and the detection unit 6 can detect the lower plate 110 and the upper plate 120 respectively, thereby improving the cleanliness and detection accuracy of the carrier 100.

(2) By providing the reversing unit 5 to reverse the cleaned lower plate 110 and the upper plate 120 , it is convenient to recover the lower plate 110 and the upper plate 120 from the picking conveying group 26 adjacent to the plate separation conveying group 21 , thereby improving the recovery efficiency of the carrier 100 .

(3) By installing the plywood unit 7, the cleaned and inspected upper plate 120 is covered on the lower plate 110, so that the lower plate 110 and the upper plate 120 can be easily recovered from the picking and conveying group 26 adjacent to the plate separation conveying group 21, thereby improving the recovery efficiency of the carrier 100.

Therefore, the plate cleanliness detection device of the present invention can indeed achieve the purpose of the present invention.

However, the above description is merely an example of the present invention and should not be used to limit the scope of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application and the content of the patent specification of the present invention are still within the scope of the present patent.
