Description

Technical Field

[0001] The present application relates to the technical field of battery chip production equipment, and in particular to a defective chip removing mechanism and a flower basket chip taking device. Background Art

[0002] Silicon wafers are important raw materials for producing battery chips. During the production of battery chips, there is a need to temporarily store silicon wafers, or intermediate form wafers from silicon wafers to battery chips, or battery chips in a flower basket. Due to the quality of the wafer itself or the instability of the insertion, there will be defective chips such as broken chips, double chips, misaligned teeth chips, ultra-thick or ultra-thin chips in the flower basket; when these wafers are taken out, they are likely to accumulate in the flower basket and cannot be taken out, which will reduce the operation rate of the machine table flower basket blanking, and thus affect the stability of the whole machine.

[0003] In order not to affect the overall operation rate of the machine table, these defective chips in the flower basket are currently picked out manually. Considering the personnel reuse rate, one person often needs to monitor 2-3 machines. However, when the machine table jams and stops feeding, the personnel often cannot clean it in time, delaying the production rhythm. Summary of the Utility Model

[0004] The present application aims to at least solve one of the technical problems existing in the prior art. For this reason, the present application provides a defective chip removing mechanism and a flower basket chip taking device, which solve the problem that defective chips in the flower basket in the prior art need to be picked out manually.

[0005] The purpose of the present application can be achieved through the following technical solutions:

[0006] In the first aspect, the present application provides a defective chip removing mechanism for removing defective wafers in a flower basket. The defective chip removing mechanism includes a chip taking platform, a wafer storage box, a transverse movement driving member, a lifting driving member, and a transfer driving member. The wafer storage box is arranged below or on the side of the chip taking platform; the chip taking platform is arranged at the driving end of the transverse movement driving member, and the transverse movement driving member is configured to drive the chip taking platform to extend into or retract from the flower basket; the transverse movement driving member is arranged at the driving end of the lifting driving member, and the lifting driving member is configured to drive the chip taking platform to lift relative to the flower basket; the transfer driving member is configured to transfer the wafers on the chip taking platform into the wafer storage box.

[0007] The defective chip removing mechanism in the present application jointly drives the chip taking platform through the lifting driving member and the transverse movement driving member, so that the chip taking platform can extend into the flower basket and extract the wafers in the flower basket from the flower basket. After the wafers are extracted from the flower basket, the transfer driving member transfers the wafers from the chip taking platform into the wafer storage box for storage, so that the defective chip removing mechanism in the present application can replace manual labor to clean and remove the defective wafers accumulated in the flower basket during the chip taking process, avoiding delaying the production rhythm due to untimely manual cleaning.

[0008] Optionally, one end of the sheet picking platform is provided with a claw for picking up the sheet, and the claw protrudes from the surface of the sheet picking platform that contacts the sheet.

[0009] With the provision of the claw, when the sheet picking platform extends into the flower basket to support the sheet to be picked and retracts out of the flower basket, the claw has a blocking effect on the sheet to be picked, which can prevent the sheet to be picked from sliding on the sheet picking platform due to inertia when the sheet picking platform retracts, and helps to drag the sheet to be picked out of the flower basket.

[0010] Optionally, a non-metallic buffer layer is provided on the surface of the claw and / or the sheet picking platform that contacts the sheet.

[0011] By providing a non-metallic buffer layer on the surface of the claw and / or the sheet picking platform that contacts the sheet, the claw and / or the sheet picking platform and the sheet can be buffered through the non-metallic buffer layer and the friction between the claw and / or the sheet picking platform and the sheet can be increased.

[0013] By setting the height h by which the claw protrudes from the sheet picking platform to a < h < 2b, the claw can pick up various defective sheets such as broken sheets, double sheets, misaligned teeth sheets, ultra-thick or ultra-thin sheets, etc., and avoid the claw from catching the sheets above the target defective sheet.

[0014] Optionally, an adsorption unit for adsorbing the sheet is provided on the sheet picking platform.

[0015] By providing an adsorption unit on the sheet picking platform, the sheet can be adsorbed on the sheet picking platform, avoiding the sheet from shaking relative to the sheet picking platform during the movement of the sheet picking platform.

[0016] Optionally, a sensor for sensing whether there is a sheet above the sheet picking platform is provided on the sheet picking platform.

[0017] By providing a sensor on the sheet picking platform, the sensor can sense whether there is a sheet above the sheet picking platform, facilitating the subsequent automatic operation of the defective sheet removing mechanism on the sheet according to the judgment result of the sensor, and improving the automation of the defective sheet removing mechanism.

[0023] Three specific transfer driving members are provided. In actual application, one or more of the transfer driving members can be selected to transfer the sheets on the sheet taking platform into the sheet storage box for storage, with a simple structure and convenient transfer.

[0024] Optionally: An avoidance groove for avoiding the flower basket is provided at one end of the sheet taking platform.

[0025] By providing an avoidance groove at one end of the sheet taking platform, the sheet taking platform can avoid some structures inside the flower basket and further extend into the flower basket to take out defective sheets.

[0026] Optionally: The defective sheet removing mechanism further includes a limiting member, and the limiting member is located on the lifting path of the sheet taking platform.

[0027] By providing the limiting member, the upper limit / or lower limit of the lifting of the sheet taking platform is limited, so as to avoid interference between the defective sheet removing mechanism and external equipment when the sheet taking platform is lifted excessively.

[0028] Optionally: The defective sheet removing mechanism further includes a cleaning member arranged below the sheet taking platform, and the cleaning member moves synchronously with the sheet taking platform and is configured to clean the debris on the movement path of the sheet taking platform.

[0029] By providing a cleaning member below the sheet taking platform, the movement path of the sheet taking platform can be synchronously cleaned while the sheet taking platform is moving.

[0030] Optionally: The defective sheet removing mechanism further includes a frame, and the lifting driving member is slidably arranged on the frame;

[0046] The following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without making creative efforts belong to the scope of protection of this application.

[0047] Please refer toFigure 1 and Figure 2 As shown in Figure 2 , the present application provides a defective wafer rejection mechanism 100 for rejecting defective wafers 500 in a carrier 600. The defective wafer rejection mechanism 100 includes a wafer picking platform 1, a wafer storage box 2, a transverse movement driving member 3, a lifting driving member 4, and a transfer driving member 5.

[0048] The wafer storage box 2 is arranged below or on the side of the wafer picking platform 1. The wafer picking platform 1 is arranged at the driving end of the transverse movement driving member 3, and the transverse movement driving member 3 is arranged at the driving end of the lifting driving member 4.

[0049] When the defective wafer rejection mechanism 100 operates, the carrier 600 is located on one side of the wafer picking platform 1. First, the lifting driving member 4 drives the transverse movement driving member 3 and the wafer picking platform 1 to synchronously descend relative to the carrier 600, so that the wafer picking platform 1 is moved in the height direction to a set height below the wafer 500 to be picked in the carrier 600. Then, the transverse movement driving member 3 drives the wafer picking platform 1 to move transversely, so that the wafer picking platform 1 extends into the carrier 600 to directly below the wafer 500 to be picked. Then, the carrier 600 descends through an external lifting driver (not shown), so that the wafer 500 to be picked falls onto the wafer picking platform 1 and is supported by it. After that, the transverse movement driving member 3 drives the wafer picking platform 1 to retract from the carrier 600, so that the wafer picking platform 1 extracts the wafer 500 to be picked from the carrier 600. Finally, the transfer driving member 5 transfers the extracted wafer 500 from the wafer picking platform 1 to the wafer storage box 2 for storage, so that the defective wafer rejection mechanism 100 in the present application can replace manual labor to reject the defective wafers 500 accumulated in the carrier 600 during the wafer picking process.

[0050] In one embodiment, after the wafer picking platform 1 extends from one side of the carrier 600 into the carrier 600 to directly below the wafer 500 to be picked, the external lifting driver (not shown) may not be selected to drive the carrier 600 to descend according to the actual situation, but the lifting driving member 4 in the present application is used to drive the wafer picking platform to rise so that the wafer 500 to be picked falls onto the wafer picking platform 1 and is supported by the wafer 500 to be picked.

[0051] In one embodiment, the transverse movement driving member 3 includes a first air cylinder 31 and a first mounting bracket 32 mounted on the driving end of the first air cylinder 31, and the wafer picking platform 1 is mounted on the first mounting bracket 32. The lifting driving member 4 includes a second air cylinder 41 and a second mounting bracket 42 mounted on the driving end of the second air cylinder 41, and the fixed end of the first air cylinder 31 is mounted on the second mounting bracket 42.

[0052] Please refer to Figure 2As shown, in one embodiment, a claw 6 is provided at one end of the wafer picking platform 1 close to the flower basket 600, and the claw 6 protrudes from the surface of the wafer picking platform 1 in contact with the wafer body 500. Through the arrangement of the claw 6, after the wafer body 500 to be picked falls onto the wafer picking platform 1, the claw 6 can hook on one side of the wafer body 500 to be picked. When the wafer picking platform 1 retracts from the flower basket 600, the claw 6 has a blocking effect on the wafer body 500 to be picked, which can prevent the wafer body 500 to be picked from sliding on the wafer picking platform 1 due to inertia when the wafer picking platform 1 retracts, and helps to drag the wafer body 500 to be picked out of the flower basket 600.

[0053] Please refer to Figure 2 、 Figure 3 and Figure 4 As shown, in one embodiment, the height h by which the claw 6 protrudes from the wafer picking platform 1 ranges from a < h < 2b, where a is the tooth gap between two adjacent teeth 601 of the flower basket 600, and b is the tooth pitch between two adjacent teeth 601 of the flower basket 600. By defining the height h by which the claw 6 protrudes from the wafer picking platform 1 as above, the claw 6 can effectively pick various defective wafer bodies 500 such as fragmented wafers, double wafers, misaligned teeth wafers, ultra-thick or ultra-thin wafers, etc., and avoid the claw 6 from hooking the wafer body 500 above the target wafer body 500 in the flower basket 600.

[0054] In one embodiment, a non-metallic buffer layer (not shown) is provided on the surface of the claw 6 and / or the wafer picking platform 1 in contact with the wafer body 500, that is, at least one of the contact surfaces of the claw 6 and the wafer picking platform 1 in contact with the wafer body 500 is provided with a non-metallic buffer layer. Through the arrangement of the non-metallic buffer layer, buffering can be carried out between the claw 6 and / or the wafer picking platform 1 and the wafer body 500 through the non-metallic buffer layer, avoiding hard contact between the claw 6 and / or the wafer picking platform 1 and the wafer body 500. Moreover, the arrangement of the non-metallic buffer layer can also effectively increase the friction force between the claw 6 and / or the wafer picking platform 1 and the wafer body 500, avoiding relative sliding between the wafer body 500 and the claw 6 and / or the wafer picking platform 1. Specifically, the non-metallic buffer layer can be composed of non-metallic materials such as ABS, Teflon or rubber.

[0055] Please refer to Figure 2 As shown, in one embodiment, an avoidance groove 7 is further provided at one end of the wafer picking platform 1 close to the flower basket 600, so that the wafer picking platform 1 can avoid some structures inside the flower basket 600 and further extend into the flower basket 600 to pick out the defective wafer body 500.

[0056] Please refer to Figure 2As shown, in one embodiment, an adsorption unit 8 for adsorbing the sheet body 500 is provided on the sheet taking platform 1. Specifically, the adsorption unit 8 can be selected to form a negative pressure cavity in the sheet taking platform 1, so that the adsorption unit 8 can firmly adsorb the sheet body 500 to be taken on the sheet taking platform 1 through the principle of vacuum negative pressure, preventing the sheet body 500 to be taken from shaking relative to the sheet taking platform 1 during the movement of the sheet taking platform 1.

[0057] Please refer to Figure 2 , in one embodiment, a sensor 9 can be arranged on the sheet taking platform 1. The sensor 9 is used to sense whether there is a sheet body 500 above the sheet taking platform 1. Specifically, after the lateral movement driving member 3 drives the sheet taking platform 1 to extend into the flower basket 600, the sensor 9 can detect whether there is a sheet body 500 to be taken above the sheet taking platform 1. Only when the sensor 9 detects that there is a sheet body 500 to be taken, the external lifting drive (not shown) drives the flower basket 600 to descend, so that the sheet body 500 in the flower basket 600 falls onto the sheet taking platform 1 and is supported by it. Another example is that after the lateral movement driving member 3 drives the sheet taking platform 1 to retract from the flower basket 600, the sensor 9 can detect whether the sheet body 500 is still on the sheet taking platform 1. Only when the sensor 9 detects that the sheet body 500 is still on the sheet taking platform 1, the defective sheet removing mechanism 100 proceeds to the next operation.

[0058] Please refer to Figure 1 and Figure 2 As shown, in one embodiment, the transfer driving member 5 includes one or more of a rotating unit 51, a pushing and sweeping unit 52, or a blowing unit.

[0059] When the transfer driving member 5 includes the rotating unit 51, the rotating unit 51 is installed on the driving end of the lateral movement driving member 3, and the sheet taking platform 1 is installed on the driving end of the rotating unit 51, and the driving end of the rotating unit 51 is in transmission connection with the sheet taking platform 1. The rotating unit 51 drives the sheet taking platform 1 to rotate, causing the sheet taking platform 1 to tilt to one side, and then the sheet body 500 to be taken on the sheet taking platform 1 slides into the sheet storage box 2. Specifically, the rotating unit 51 can be selected as a cylinder, the fixed end of the cylinder is installed on the driving end of the lateral movement driving member 3, and the sheet taking platform 1 is installed on the driving end of the cylinder.

[0060] When the transfer driving member 5 includes the pushing and sweeping unit 52, the pushing and sweeping unit 52 can reciprocate between the sheet taking platform 1 and the sheet storage box 2, and then push and sweep the sheet body 500 on the sheet taking platform 1 into the sheet storage box 2. Specifically, as Figure 1 shown, the pushing and sweeping unit 52 includes a third cylinder 521 and a broom 522 installed on the driving end of the third cylinder 521. The third cylinder 521 is fixedly installed on one side of the lateral movement driving member 3. The third cylinder 521 drives the broom 522 to extend and retract to push and sweep the sheet body 500 on the sheet taking platform 1 into the sheet storage box 2 and then reset.

[0061] When the transfer driving member 5 includes a blowing unit (not shown), the blowing unit is disposed above the sheet taking platform 1 and close to the sheet storage box 2, or disposed below the sheet taking platform 1 and away from the sheet storage box 2. The blowing unit blows air to the portion of the sheet to be taken 500 extending out of the sheet taking platform 1, so that the sheet to be taken 500 is lifted from the sheet taking platform 1 and slides into the sheet storage box 2.

[0062] In one embodiment, as Figure 1 shown, the transfer driving member 5 includes a rotating unit 51 and a pushing and sweeping unit 52. When transferring the sheet 500, the rotating unit 51 can first rotate the sheet taking platform 1 to tilt the sheet taking platform 1 to one side, so that the sheet 500 slides into the sheet storage box 2 and then resets. Then, the pushing and sweeping unit 52 sweeps the sheet taking platform 1 to sweep the possible remaining debris, scraps, and residues on the sheet taking platform 1 into the sheet storage box 2 to ensure the cleanliness of the sheet taking platform 1.

[0063] In one embodiment, the transfer driving member 5 includes a blowing unit (not shown) and a pushing and sweeping unit 52. When transferring the sheet 500, the blowing unit first blows air to the portion of the sheet 500 extending out of the sheet taking platform 1 to lift the sheet 500 from the sheet taking platform 1 and slide it into the sheet storage box 2, and then the pushing and sweeping unit 52 sweeps the sheet taking platform 1 to sweep the possible remaining debris, scraps, and residues on the sheet taking platform 1 into the sheet storage box 2 to ensure the cleanliness of the sheet taking platform 1.

[0064] Please refer to Figure 1 shown, in one embodiment, to enable the defective sheet removing mechanism 100 to perform the operation of removing defective sheets from multiple flower baskets 600. The defective sheet removing mechanism 100 further includes a frame 10, and the lifting driving member 4 is slidably disposed on the frame 10. By changing the position of the lifting driving member 4 on the frame 10, the sheet taking platform 1 can be aligned with a plurality of flower baskets 600 distributed along the sliding direction of the lifting driving member 4 one by one.

[0065] In some embodiments, the sheet storage box 2 is slidably disposed on the frame 10, and the sheet storage box 2 can be slid on the frame 10 according to requirements to adjust the distance between the sheet storage box 2 and the sheet taking platform 1, which helps the transfer driving member 5 transfer the defective sheets on the sheet taking platform 1 into the sheet storage box 2.

[0066] Of course, in some embodiments, both the lifting driving member 4 and the sheet storage box 2 are slidably disposed on the frame 10.

[0067] Specifically, the defective wafer rejection mechanism 100 further includes a mounting plate 11 and a translation driving member 12. A slide rail 13 is provided on the frame 10 in the vertical direction. The mounting plate 11 is slidably mounted on the slide rail 13 through a slider. The translation driving member 12 is mounted on the frame 10 and is configured to drive the mounting plate 11 to move along the slide rail 13. The fixed end of the lifting driving member 4 is fixedly mounted on the mounting plate 11.

[0068] Please refer to Figure 1 As shown, in one embodiment, the defective wafer rejection mechanism 100 further includes a limiting member 14. The limiting member 14 is located on the lifting path of the wafer picking platform 1. Specifically, the limiting member 14 is fixedly mounted on the mounting plate 11 and is used to stop the transverse movement driving member 3 during its downward movement, so that the limiting member 14 limits the lower limit of the lifting of the wafer picking platform 1 by stopping the transverse movement driving member 3, avoiding the wafer picking platform 1 from descending excessively and colliding with the external equipment below (such as Figure 5 the wafer picking mechanism 400 in

[0069] In some embodiments, the defective wafer rejection mechanism 100 further includes a cleaning member (not shown) disposed below the wafer picking platform 1. The cleaning member is mounted on the bottom of the wafer picking platform 1 and moves synchronously with the wafer picking platform 1. The cleaning member is used to clean the debris on the movement path of the wafer picking platform 1. After the defective wafer rejection mechanism 100 is used in cooperation with the wafer picking mechanism 40, the cleaning member can sweep away the debris, chips, slag, etc. on the wafer picking mechanism 400, ensuring the cleanliness of the conveying path of the wafer picking mechanism 400. Specifically, the cleaning member can be selected from a brush or a blowing unit, and the brush or the blowing unit is fixedly arranged at the bottom of the wafer picking platform 1.

[0070] Please refer to Figure 5 As shown, in the embodiment of the present application, a flower basket wafer picking device 200 is further provided. The flower basket wafer picking device 200 includes a flower basket clamping mechanism 300, a wafer picking mechanism 400, and the defective wafer rejection mechanism 100 as described above;

[0071] The flower basket clamping mechanism 300 is disposed at one end of the wafer picking mechanism 400 and is used to clamp the flower basket 600 to be picked up;

[0072] The wafer picking mechanism 400 is used to pick out the wafers 500 in the flower basket 600 one by one;

[0073] The defective wafer rejection mechanism 100 is disposed above the wafer picking mechanism 400 and is used to take out the defective wafers 500 in the flower basket 600.

[0074] When the basket sheet taking device 200 operates, the sheet taking mechanism 400 takes out the good sheets 500 in the basket 600 one by one from bottom to top. However, when a defective sheet 500 is detected, the sheet taking mechanism 400 pauses the sheet taking operation, and the defective sheet removing mechanism 100 removes the defective sheets in the basket 600. After that, the sheet taking mechanism 400 continues the sheet taking operation.

[0075] In the basket sheet taking device 200 of the present application, the defective sheet removing mechanism 100 automatically takes out the defective sheets in the basket 600, avoiding the influence of manual cleaning of the defective sheets in the basket 600 on the overall operation rate of the basket sheet taking device 200.
