Description

Technical Field

[0001] This utility model relates to the technical field of electrode detection, specifically a positive electrode detection machine that can mark defective products. Background Technology

[0002] Lithium batteries are widely used in many fields such as power tools, electric vehicles, and portable appliances, and the electrode is one of the important internal components of a lithium battery. During the manufacturing process of the electrode, defects are inevitable. Using defective electrodes in lithium batteries poses certain safety hazards. Therefore, it is necessary to inspect the electrode burrs.

[0003] During the testing of electrode sheets, defective electrode sheets need to be removed to facilitate recycling and reuse. In order to distinguish defective electrode sheets from finished products, a marking mechanism is needed to assist in the work. However, the existing electrode sheet testing machine lacks a mechanism for marking defective products.

[0004] To address the aforementioned deficiencies, a visual inspection system for battery electrodes can be described in the prior art (Chinese patent application number CN201620663123.8, publication date 2016-12-21). This inspection system can mark the left and right electrodes using a marking device. When the left electrode is defective, it is marked; conversely, when the right electrode is defective, it is marked.

[0005] Although the above-mentioned device can perform marking, there are still other problems in the operation process. After the test items are tested, the defective products need to be collected and processed in a centralized manner. However, the existing technology only marks the end of the work, resulting in waste remaining on the top of the workbench. Therefore, there are still some shortcomings in the testing process.

[0006] Therefore, we proposed a positive electrode plate inspection machine that can mark defective products, which can effectively solve the above problems. Utility Model Content

[0007] The purpose of this invention is to provide a positive electrode testing machine that can mark defective products, in order to solve the problem mentioned in the background art that the current electrode testing machines on the market need to collect and process defective products after testing the products to be tested, while the existing technology simply ends the work by marking, resulting in waste still remaining on the top of the workbench.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a positive electrode plate inspection machine for marking defective products, including a visual inspection component installed on the top of the frame, and a waste collection box placed inside the bottom of the frame;

[0009] It also includes: a marking component is installed on the top of the frame near the rear of the vision inspection component; an air supply component is fixedly installed on the left side wall of the frame; a first air supply pipe is connected to the output end of the air supply component; the outer end of the first air supply pipe extends into the interior of the frame and is connected to a limiting mechanism; the inner side of the limiting mechanism is attached to the inner side of the positive electrode sheet; a feeding port is provided on the inner side of the frame to facilitate material feeding; the center line of the feeding port is collinear with the center line of the waste collection box.

[0010] The limiting mechanism includes two sets of vertical plates that slide inside the feed port. A positioning mechanism is provided on the inner side of the vertical plates to achieve the centering and positioning of the positive electrode sheet.

[0012] As a preferred technical solution of this application, the limiting mechanism also includes a connecting pipe connected to the outlet end of the first gas supply pipe. The middle outer side of the connecting pipe is fixed to the inner wall of the frame. Two sets of sliding pipes are slidably arranged inside the connecting pipe. One end of the two sets of sliding pipes is connected to each other by a return spring. The outer ends of the two sets of sliding pipes are fixed to one side of the vertical plate, so that the vertical plate can slide inside the feed port. The limiting mechanism can be used to limit the positive electrode sheet by the two sets of vertical plates.

[0013] As a preferred technical solution of this application, a one-way air inlet valve is provided at one end of the sliding tube inside the connecting tube, and an air vent is provided at the end of the sliding tube near the vertical plate, which can be used to vent air, thereby facilitating the subsequent unloading of defective products.

[0014] As a preferred technical solution of this application, the positioning mechanism includes a through pipe inside the vertical plate, the air outlet of the through pipe being connected to the bottom of the lifting rod, the top of the lifting rod being fixed to the rear side of the upper limit block, the rear sides of the upper limit block being slidably disposed inside the mating groove, the mating groove being opened on the inner side of the vertical plate, a piston block being fixed to the bottom of the upper limit block, the bottom of the piston block being fitted into a cavity opened inside the upper limit block, the bottom of the cavity being connected to the bottom end of the telescopic rod through a second air supply pipe, and the top end of the telescopic rod being rotatably disposed at the bottom of the lower limit plate. The positioning mechanism can be used to position the positive electrode sheet.

[0015] As a preferred technical solution of this application, the rear side of the lower limiting plate is rotatably disposed on the surface of the vertical plate, and the bottom position of the telescopic rod is rotatably disposed below the vertical plate. The air inlet of the through pipe is connected to the end of the sliding pipe, and the positioning of the positive electrode sheet can be achieved by rotating the lower limiting plate.

[0016] As a preferred technical solution of this application, the lower limiting plate forms a rotating structure between the surface of the telescopic rod and the vertical plate, and the rotation range of the lower limiting plate is 0 to 90 degrees. A rubber ring is nested on the bottom outer side of the piston block, and the outer wall of the rubber ring is attached to the inner wall of the cavity.

[0020] Furthermore, a sliding tube is installed, and a one-way gas valve is installed at one end of the sliding tube to absorb the gas inside the tube, so that the rod inside the lifting rod can be lowered, which can drive the upper limit block to be lowered. The positive electrode is centered and positioned by setting the lower limit plate and the upper limit block.

[0021] Furthermore, a vent is installed to release the gas inside the lifting rod. By resetting the lifting rod, the lower limit plate can be rotated downwards, which facilitates the feeding of positive electrode sheets and the feeding of defective products through the feeding port.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-8 The present invention provides the following technical solution:

[0033] Example 1: To limit the position of the positive electrode, please refer to the attached diagram. Figure 1 Appendix Figure 2 Appendix Figure 4 and attached Figure 5The system includes a vision inspection component 3 mounted on the top of the frame 1, and a waste collection bin 5 placed inside the bottom of the frame 1. It also includes a marking component 4 mounted on the top of the frame 1 near the rear of the vision inspection component 3, and an air supply component 6 fixedly mounted on the left side wall of the frame 1. The output end of the air supply component 6 is connected to a first air supply pipe 7, the outer end of which extends into the interior of the frame 1 and connects to a limiting mechanism. The inner side of the limiting mechanism is fitted against the inner side of the positive electrode sheet. An opening on the inner side of the frame 1 facilitates material unloading. The discharge port 20 is collinear with the center line of the waste collection box 5. The limiting mechanism also includes a connecting pipe 8 connected to the outlet end of the first air supply pipe 7. The outer side of the middle part of the connecting pipe 8 is fixed to the inner wall of the frame 1. Two sets of sliding pipes 9 are slidably arranged inside the connecting pipe 8. The two sets of sliding pipes 9 are connected at one end inside the connecting pipe 8 by a return spring 10. The outer ends of the two sets of sliding pipes 9 are fixed to one side of the vertical plate 11, so that the vertical plate 11 can slide inside the discharge port 20. A one-way air inlet valve is provided at one end of the sliding pipe 9 inside the connecting pipe 8, and an air vent is provided at the end of the sliding pipe 9 near the vertical plate 11.

[0034] First, the positive electrode sheet is moved by a suction cup robot. Then, the gas supply component 6 is controlled by the control component 2 to operate, so that the gas supply end of the gas supply component 6 can supply gas to the inside of the first gas supply pipe 7, so that the gas can be delivered to the inside of the connecting pipe 8. The sliding pipe 9 inside the connecting pipe 8 can move relative to each other, so that the two sets of sliding pipes 9 can drive the vertical plate 11 to work relative to each other. At this time, the inner side of the vertical plate 11 will be close to the outer side of the positive electrode sheet, so that the positive electrode sheet can be limited. The continued suction operation can open the one-way gas valve inside the sliding pipe 9, so that the inside of the lifting rod 13 can be attracted through the through pipe 12. At this time, the piston block 16 will also move through one end of the lifting rod 13, so that the bottom of the piston block 16 can slide in the cavity, so that the gas is squeezed into the inside of the second gas supply pipe 17, so that the inside of the telescopic rod 18 can be filled with gas, so that the telescopic rod 18 can be extended, so that the lower limit plate 19 will be lifted, thereby facilitating the centering and positioning of the positive electrode sheet.

[0035] Example 2: To mark the positive electrode sheet to be tested, please refer to the attached document. Figure 1 - Appendix Figure 3A marking component 4 is installed on the top of the frame 1 near the rear of the vision inspection component 3. The marking component 4 includes a first electric push rod 41 fixed to the inner wall of the frame 1. The output end of the first electric push rod 41 is fixed to the outside of a second electric push rod 42. A marking pen 43 is attached to the vertically downward output end of the second electric push rod 42. The marking pen 43 and the vision inspection component 3 are on the same vertical line. When the positive electrode sheet is positioned, the vision inspection component 3 is then inspected by the control component 2. If the inspected positive electrode sheet is qualified, it is adsorbed by a suction cup robot, and air is supplied to the first air supply pipe 7 through the air supply component 6, releasing the positioning of the positive electrode sheet, allowing for subsequent handling. Alternatively, if a defective product is detected, the marking component 4 can be activated by the control component 2, causing the first electric push rod 41 of the marking component 4 to operate, and the second electric push rod 42 can also mark the defective product with the marking pen 43.

[0036] Example 3: To address the issue that current electrode testing machines on the market require centralized collection and processing of defective products after testing, but existing technologies only mark the samples and then stop the process, resulting in waste remaining on the top of the workbench, please refer to the attached... Figure 1 and attached Figure 6 -Appendix Figure 8 The limiting mechanism includes two sets of vertical plates 11 slidably disposed inside the feed port 20. A positioning mechanism is provided on the inner side of the vertical plates 11, which enables the positive electrode sheet to be positioned in the center. The positioning mechanism includes a through pipe 12 disposed inside the vertical plates 11. The air outlet of the through pipe 12 is connected to the bottom position of the lifting rod 13. The top of the lifting rod 13 is fixed to the rear side of the upper limit block 14. The rear sides of the upper limit block 14 are slidably disposed inside the mating groove 15, which is located inside the vertical plates 11. A piston block 16 is fixed to the bottom position of the upper limit block 14. The bottom of the piston block 16 fits into the cavity inside the upper limit block 14. The bottom position of the cavity is connected to the bottom position of the telescopic rod 18 through the second air supply pipe 17. The top position of the telescopic rod 18 is rotatably disposed at the bottom position of the lower limiting plate 19. The lower limit plate 19 is rotatably mounted on the surface of the vertical plate 11 at its rear side, and the bottom position of the telescopic rod 18 is rotatably mounted below the vertical plate 11. The air inlet of the through pipe 12 is connected to the end of the sliding pipe 9. The lower limit plate 19 forms a rotating structure with the surface of the vertical plate 11 through the telescopic rod 18, and the rotation range of the lower limit plate 19 is 0 to 90 degrees. A rubber ring is nested on the outer bottom of the piston block 16, and the outer wall of the rubber ring is attached to the inner wall of the cavity.

[0037] When it is necessary to collect defective products, the vent can be opened to release the gas inside the vent pipe 12. At this time, the spring inside the lifting rod 13 will reset, which will cause the upper limit block 14 to move upward, and the movement of the piston block 16 will draw air into the second air supply pipe 17, causing the telescopic rod 18 to retract and the lower limit plate 19 to rotate downward. At this time, the area below the defective product will be suspended, making it easier for the defective product to fall into the discharge port 20 and the waste collection box 5, thus facilitating the collection of defective products.

[0038] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
