Description

Technical Field

[0001] The present application relates to the technical field of silicon wafer production, and in particular to a stacking repair device and a re-inspection bagging device. Background Art

[0002] After the silicon wafers are inspected and sorted by the sorting machine, the qualified silicon wafers will be stacked in the material box in sequence. The silicon wafers are stacked into stacks in the material box. Then the stacks in the material box are taken out and transported to the stack inspection device for appearance inspection of the stack. If the stack inspection is qualified, the qualified stack will be sent to the next process for bagging and packaging through the conveying mechanism.

[0003] If the stacking detection device detects unqualified stacking, the handling mechanism will send the unqualified stacking to the maintenance station for manual repair, and then the handling mechanism needs to wait for the stacking detection device to complete the inspection of the next stacking. If the next stacking is qualified, the handling mechanism can send the qualified stacking to the next process. Therefore, when no qualified stacking is sent to the next process, the equipment of the next process can only stop and wait, resulting in low production efficiency. Summary of the invention

[0076] Some embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the protection scope of the present application.

[0077] As described in the background technology, if the stack detection device detects unqualified stacks, the handling mechanism will send the unqualified stacks to the maintenance station for manual repair, and then the handling mechanism needs to wait for the stack detection device to complete the next stack detection. If the next stack is qualified, the handling mechanism can send the qualified stack to the next process. Therefore, when there are no qualified stacks sent to the next process, the equipment of the next process can only stop and wait, which has the problem of low production efficiency. Based on this, the present application proposes a stack maintenance device to solve the problem of low stack production efficiency.

[0078] See attached Figure 1 , Figure 1 Schematic diagram of the structure of a lamination repair device according to an embodiment of the present application. Figure 1 As shown, in one or more embodiments, the stack repair device of the present application includes a first conveying mechanism 10, a first detection mechanism 20, a first handling mechanism 30 and a second conveying mechanism 40, wherein: a first detection station is provided on the first conveying mechanism 10, the first detection mechanism 20 is located at the first detection station, and the first detection mechanism 20 is configured to perform a first type of detection on the stack conveyed by the first conveying mechanism 10 to the first detection station in a step-by-step manner; the first conveying mechanism 10 is also configured to convey the stack detected at the first detection station to the discharge station in a step-by-step manner; the first handling mechanism 30 is configured to pick up the stack located at the discharge station The first conveying mechanism 40 is configured to receive the unqualified laminates transported by the first conveying mechanism 30 and transport the unqualified laminates to the maintenance station for maintenance. The second conveying mechanism 40 is also configured to receive the qualified laminates after maintenance at the maintenance station and transport the qualified laminates to the picking range of the first conveying mechanism 30. The first conveying mechanism 30 is also configured to pick up the qualified laminates after maintenance on the second conveying mechanism 40 and transport the qualified laminates to the next process. Specifically, the first type of inspection can be to inspect the appearance of the laminates.

[0079] The stack inspection device of the embodiment of the present application sends unqualified stacks to the second conveying mechanism 40 through the first transport mechanism 30, and picks up the stacks that have passed the previous inspection from the second conveying mechanism 40 and sends them to the next process. The stack bagging equipment of the next process does not need to stop and wait, and the stacks after inspection do not need to enter the inspection mechanism for re-inspection, which effectively improves production efficiency.

[0080] In one embodiment, see Figure 1 and Figure 2 , the second conveying mechanism 40 includes a first conveying component 41 and a second conveying component 42;

[0081] The first conveying assembly 41 is configured to receive the unqualified stacks conveyed by the first conveying mechanism 30 through the material box and convey the unqualified stacks to the maintenance station;

[0082] The second conveying assembly 42 is configured to receive qualified stacks after inspection at the inspection station through a material box and convey the qualified stacks to the picking range of the first transport mechanism 30 .

[0083] Specifically, the first conveying assembly 41 and the second conveying assembly 42 can be set according to the actual picking range position of the first conveying mechanism 30 and the position of the maintenance station. The first conveying assembly 41 conveys unqualified stacks to the maintenance station for manual or equipment to take away and repair the stacks; the second conveying assembly 42 conveys qualified stacks after maintenance to the picking range of the first conveying mechanism 30, so that the first conveying mechanism 30 can pick up qualified stacks and transport them to the bagging equipment for bagging, so as to improve production efficiency. Furthermore, the first conveying assembly 41 and the second conveying assembly 42 both carry and transport stacks through material boxes, which have a stabilizing effect on the stacks and can effectively prevent the stacks from displacement and damage during transportation.

[0084] By setting up the second conveying mechanism 40, it is possible to convey unqualified stacking sheets and qualified stacking sheets after inspection respectively through different conveying lines, so that the first conveying mechanism 30 can select the corresponding conveying component to place unqualified stacking sheets or pick up qualified stacking sheets after inspection according to the conveying requirements without stopping for waiting. A conveying mechanism that can convey unqualified stacking sheets and qualified stacking sheets after inspection simultaneously is provided, which has high conveying efficiency, ensures the conveying efficiency of the first conveying mechanism, and further improves production efficiency.

[0087] The second position is close to the feeding end of the first conveying assembly 41 , and the first conveying member 432 located at the second position is configured to convey the temporarily stored unqualified stacks to the first conveying assembly 41 .

[0088] Specifically, the first conveying assembly 41 and the second conveying assembly 42 are arranged in the Z direction in an upper and lower layer structure to save space; the first conveying assembly 41 conveys unqualified stacking sheets along the X1 direction, and the second conveying assembly 42 conveys qualified stacking sheets after inspection along the X2 direction. The X1 direction and the X2 direction are opposite and perpendicular to the Z direction to ensure stable transportation of the stacking sheets; the first conveying assembly 41 is arranged below the second conveying assembly 42, and the height of the second conveying assembly 42 is set according to the height of the inspection station. The height needs to be convenient for manual or equipment to pick up or place the stacking sheets. Since the second conveying assembly 42 conveys qualified stacking sheets after inspection, the second conveying assembly 42 is set at this height, and the qualified stacking sheets after inspection do not need to adjust the height position during the transportation journey from the inspection station back to the picking range of the first conveying mechanism 30, thereby avoiding the shaking problem of the qualified stacking sheets after inspection due to height adjustment.

[0089] Specifically, the first driving member 431 can adopt a linear module, and the first driving member 431 drives the first conveying member 432 to rise and fall vertically along the Z direction so that the first conveying member 432 moves alternately to the first position or the second position; the first conveying member 432 can adopt a pulley assembly, and the conveying direction of the pulley assembly is the same as that of the first conveying assembly 41 and the second conveying assembly 42. It can receive qualified stacking sheets after inspection from the second conveying assembly 42, and can also convey unqualified stacking sheets to the first conveying assembly 41.

[0094] Specifically, the receiving end of the third conveying mechanism 50 is arranged close to the second position so that the first conveying member 432 can convey the empty material box to the third conveying mechanism 50. The specific conveying direction and path of the third conveying mechanism 50 can be specifically set according to the position of the actual material box recovery station, and no specific restrictions are made in this application. The first conveying member 432 can use multiple groups of pulley assemblies with different conveying directions to achieve feeding in different directions. It should be understood that the third conveying mechanism 50 can also be set at any height position that the first conveying member 432 can reach along the Z direction, which can be set according to the actual material box recovery process.

[0095] Through the cooperation of the first lifting and conveying assembly 43 and the third conveying mechanism 50, the empty material box with the stacked sheets removed can be recycled, which is beneficial to the subsequent recycling of the empty material box.

The second conveying member 442 located at the fourth position is configured to convey the temporarily stored unqualified stacks to the maintenance station or receive qualified stacks after maintenance of unqualified stacks through a material box and convey the qualified stacks to the second conveying component 42.
