Description

[0002] During the battery assembly process, the removal of glue pins and the extraction of gas are two important processes. The removal of glue pins is usually to facilitate the discharge or introduction of gas inside the battery to ensure that the air tightness and safety of the battery meet the requirements, while the extraction of gas is to remove the harmful gas remaining inside the battery to avoid affecting the battery performance or causing safety hazards.

[0003] In the prior art, nail pulling and air extraction processes are generally carried out independently, and nail pulling equipment and air extraction equipment need to be set up separately. This decentralized equipment layout complicates the production line, not only taking up a large production space, but also increasing the difficulty of debugging and maintenance costs between equipment. In addition, the battery needs to be transferred multiple times between the nail pulling and air extraction processes, which can easily affect production efficiency.

[0004] In addition, in existing nail pulling equipment, the manipulator usually directly pulls out the rubber nails, and dust or debris will inevitably be generated during the operation. These dusts may enter the battery and affect the air tightness and overall performance of the battery. Especially during the nail pulling process, trace amounts of gas may escape from the battery. If these gases are not collected and treated in time, they may not only cause pollution, but also have adverse effects on the health of operators. Summary of the invention

[0039] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation methods and the accompanying drawings.

[0040] This embodiment discloses a battery nail removal and exhaust device that integrates nail extraction and air extraction functions, aiming to solve the problems of scattered equipment, complicated processes and insufficient pollution prevention and control in the prior art. Figures 1 to 4 The device includes a first positioning bracket 20, a second positioning bracket 30, a conveying line 1, a nail pulling mechanism 2 and an air extraction mechanism 3.

[0041] The first positioning bracket 20 and the second positioning bracket 30 are arranged in parallel and are used to place the restraint tray P with the battery BT.

[0042] The conveyor line 1 is used to drive the restraining pallet P to transfer between the first positioning bracket 20 and the second positioning bracket 30 .

[0043] like Figures 5 to 9 The nail pulling mechanism 2 includes a first gantry 21 arranged above the first positioning bracket 20 and a manipulator 22 arranged on the first gantry 21 and capable of lifting and lowering relative to the restraint tray P. The manipulator 22 is used to remove the glue nails J on the battery BT in the restraint tray P.

[0044] like Fig.10 and Fig.11 The manipulator 22 is provided with a protective cover 23, which includes a first connection end 230 and a second connection end 231 at both ends, and a cover body 232 located between the first connection end 230 and the second connection end 231, and the length of the cover body 232 can be telescopically changed. In this embodiment, the protective cover 23 is an accordion cover, and the material is soft silicone, rubber, polyurethane resin, coated soft rubber, etc., and is integrally formed by 3D printing technology.

[0045] The first connection end 230 is sealed and connected to the fixed part of the manipulator 22, and the second connection end 231 is used to be sealed and connected to the part outside the glue nail J on the battery BT. The second connection end 231 is provided with an opening 2310 connected to the internal space of the protective cover 23, and the manipulator 22 is close to the glue nail J based on the opening 2310. The first connection end 230 is also provided with an exhaust port 234 connected to the internal space of the protective cover 23.

[0046] like Figure 2 and Figure 3 The exhaust mechanism 3 includes a second gantry 31 located above the second positioning bracket 30 and an exhaust head 32 arranged on the second gantry 31 and capable of relatively restraining the lifting and lowering movement of the tray P. The exhaust head 32 is used to dock with the glue nail J hole on the battery BT to extract the gas in the battery BT.

[0047] For the above-mentioned battery glue nail disengagement and exhaust device, specifically, through the first positioning bracket 20 and the second positioning bracket 30 arranged in parallel, in cooperation with the conveyor line 1, the efficient transfer of the restraint tray P containing the battery BT between the nail pulling and exhaust processes is realized. The nail pulling mechanism 2 adopts a manipulator 22 arranged on the first gantry 21. The manipulator 22 can move up and down relative to the restraint tray P in the vertical direction to accurately remove the glue nails J on the battery BT in the tray. In this process, the protective cover 23 outside the manipulator 22 effectively protects the nail pulling process through a sealed connection design, and its cover body 232 has a telescopic function and can adapt to the movement of the manipulator 22. The protective cover 23 can not only prevent dust and debris generated during nail pulling from entering the battery BT body, but also efficiently collect and discharge escaping gases through the sealed connection and exhaust port 234 design to avoid polluting the production environment.

[0048] At the same time, the exhaust mechanism 3 achieves precise docking with the J-hole of the battery BT nail through the exhaust head 32 located on the second gantry 31, and quickly extracts the internal gas of the battery BT after the nail is pulled out.

[0049] The battery glue nail separation and exhaust device in this embodiment integrates the two processes of nail extraction and air extraction on the same production line, which significantly simplifies the process flow and reduces the space occupied by equipment and the transfer cost.

[0050] The design of the protective cover 23 also effectively solves the problems of dust pollution and gas escape during the nail removal and air extraction process, which not only ensures the air tightness and stable performance of the battery BT, but also significantly improves the safety and cleanliness of the production environment, and has important application value.

[0051] On the other hand, Fig.10 and Fig.11 The first connection end 230 is also provided with an air inlet 233 which is connected to the inner space of the protective cover 23 .

[0052] After the second connection end 231 of the protective cover 23 abuts against the battery BT, before the manipulator 22 performs the nail pulling action, air is inflated into the protective cover 23 through the air inlet 233 to make the air pressure inside the protective cover 23 equivalent to that inside the battery BT, thereby avoiding the electrolyte in the battery BT from spraying out due to the low air pressure inside the protective cover 23.

[0053] On the other hand, Figures 6 to 9 The nail extraction mechanism 2 also includes a first mounting frame 240 and a second mounting frame 241. The first mounting frame 240 is slidably connected to the first gantry 21 through a sliding mechanism 25. The second mounting frame 241 is connected to the first mounting frame 240 through a first lifting mechanism 26. The manipulator 22 is installed on the second mounting frame 241. The sliding mechanism 25 is used to drive the first mounting frame 240 to move along the first axial direction, so that the manipulator 22 can reciprocate on both sides of the restraint pallet P, thereby performing the glue nail J extraction work on the two rows of batteries BT on both sides of the restraint pallet P. Specifically, the sliding mechanism 25 includes a relatively arranged driven slide rail 251 and an active slide rail 250 with a sliding driver. The two ends of the first mounting frame 240 are respectively connected to the active slide rail 250 and the driven slide rail 251, and the first mounting frame 240 is driven to reciprocate on both sides of the restraint pallet P through the sliding driver on the active slide rail 250.

[0054] The first lifting mechanism 26 is used to drive the second mounting frame 241 to move up and down relative to the restraint tray P, so that the robot arm 22 is close to or away from the glue nails J on the battery BT.

[0055] More specifically, the first lifting mechanism 26 includes a guide rod 260 and a first lifting driver 261. One end of the guide rod 260 is fixedly connected to the second mounting frame 241, and the other end of the guide rod 260 passes through the first mounting frame 240 upward, and the guide rod 260 can move relative to the first mounting frame 240. The first lifting driver 261 is arranged on the first mounting frame 240, and the driving end of the first lifting driver 261 is connected to the second mounting frame 241. The first lifting driver 261 is used to drive the second mounting frame 241 to move up and down. The first lifting driver 261 in this embodiment can be a linear motion driving device such as a cylinder and a motor.

[0056] On the other hand, please refer again to Fig.10 and Fig.11 The manipulator 22 includes two clamping jaws 220 arranged opposite to each other, and the work of grabbing or releasing the rubber nail J is achieved by controlling the two clamping jaws 220 to move closer to or farther away from each other.

[0057] In this regard, Figure 8 , Fig. 9 and Fig.12The nail pulling mechanism 2 further includes a third mounting frame 242 located at the bottom of the second mounting frame 241 and connected to the second mounting frame 241. A first linkage rod 270 and a second linkage rod 271 are disposed at the bottom of the third mounting frame 242. The first linkage rod 270 and the second linkage rod 271 are slidably connected to the third mounting frame 242 so that the first linkage rod 270 and the second linkage rod 271 can move along the second axial direction. One of the two clamping jaws 220 is connected to the first linkage rod 270, and the other of the two clamping jaws 220 is connected to the second linkage rod 271.

[0058] The second mounting frame 241 is provided with a first clamping jaw driver 272 connected to the first linkage rod 270 and a second clamping jaw driver 273 connected to the second linkage rod 271. The first clamping jaw driver 272 and the second clamping jaw driver 273 are respectively used to drive the first linkage rod 270 and the second linkage rod 271 to move, so that the two clamping jaws 220 are in an open or closed state. When the two clamping jaws 220 are in a closed state, a clamping action is realized, and when the two clamping jaws 220 are in an open state, a releasing action is realized.

[0059] On the other hand, Figure 8 , Fig. 9 and Fig.13 A pressure rod 280 is also arranged in parallel on one side of the manipulator 22. The pressure rod 280 is connected to a connecting seat 281 extending outward from the second mounting frame 241 through a connecting rod 282. An elastic member 283 is sleeved on the connecting rod 282. One end of the elastic member 283 abuts against the pressure rod 280, and the other end of the elastic member 283 abuts against the connecting seat 281.

[0060] When the pressing rod 280 is subjected to upward extrusion force, it can slide upward along the connecting rod 282 to press the elastic member 283. When the manipulator 22 pulls out the nail J to within a preset height, the elastic member 283 is always in a compressed state, so that the pressing rod 280 is pressed low on the battery BT.

[0061] In this embodiment, the elastic member 283 is always in a compressed state during the whole process from the contact between the robot 22 and the plastic nail J to the pulling out of the plastic nail J, so that the pressure rod 280 is always pressed on the battery BT to prevent the robot 22 from pulling the battery BT out of the restraint tray P.

[0062] Specifically, a connecting shaft 284 is embedded in the pressure rod 280 , and a connecting hole 285 matched with the connecting shaft 284 is provided at one end of the connecting rod 282 close to the pressure rod 280 . Based on the connecting hole 285 , the pressure rod 280 is sleeved on the connecting shaft 284 , and the connecting shaft 284 can slide in the connecting hole 285 .

[0063] On the other hand, Figure 6A material receiving box 4 is also provided on one side of the first gantry 21 , and the material receiving box 4 is used to receive the glue nails J pulled out by the robot 22 .

[0064] The working process of the nail pulling mechanism 2 with the above structure is:

[0065] 1. The restraint tray P with the battery BT is received by the conveyor line 1 and conveyed to the first positioning bracket 20 .

[0066] 2. Start the sliding mechanism 25 on the first gantry 21 to drive the first mounting frame 240 to move to the target position.

[0067] 3. Start the first lifting driver 261 to drive the second mounting frame 241 and the third mounting frame 242 to move downward until the manipulator 22 contacts the glue nail J. During the downward movement, the pressing rod 280 first contacts the edge of the battery BT, and the pressing rod 280 moves upward for a distance relative to the connecting rod 282, so that the elastic member 283 is compressed, and the elastic restoring force generated by the elastic member 283 presses the pressing rod 280 on the battery BT.

[0068] When the second connection end 231 of the protective cover 23 contacts the part around the glue nail J on the battery BT body, the second connection end 231 is attached to the battery BT to cover the location of the glue nail J in the protective cover 23. As the manipulator 22 moves further downward, the cover body 232 of the protective cover 23 is in a compressed state.

[0069] 4. Ventilate the protective cover 23 through the air inlet 233 to prevent the electrolyte from spraying out due to excessive pressure difference between the inside and outside of the battery BT after the rubber nail J is pulled out.

[0070] 5. The first clamping jaw driver 272 and the second clamping jaw driver 273 are activated to activate the first linkage rod 270 and the second linkage rod 271, thereby driving the two clamping jaws 220 constituting the manipulator 22 to approach each other to clamp the plastic nail J.

[0071] 6. The first lifting driver 261 drives the second mounting frame 241 and the third mounting frame 242 to move up a certain distance (e.g., 5 mm) to drive the manipulator 22 to move up, thereby pulling out the glue nail J. At this time, the second connecting end 231 of the protective cover 23 is still attached to the battery BT, and the pressing rod 280 is still pressed on the battery BT.

[0072] 7. After the rubber nail J is pulled out, the high-pressure gas generated inside the battery BT escapes into the protective cover 23 . At this time, the gas in the protective cover 23 is extracted through the exhaust port 234 .

[0073] 8. The first lifting driver 261 drives the second mounting frame 241 and the third mounting frame 242 to continue to move upward, so that the protective cover 23 is separated from the battery BT.

[0074] 9. Then, the sliding mechanism 25 is started again to move the manipulator 22 to the position of the material receiving box 4 to release the glue nails J on the manipulator 22, and the glue nails J automatically fall into the material receiving box 4.

[0075] 10. The sliding mechanism 25 drives the manipulator 22 to reset so that it can work accurately next time.

[0076] On the other hand, Fig.14 and Fig.15 A fourth mounting frame 33 is provided on the second gantry 31, and the exhaust head 32 is installed on the fourth mounting frame 33. The fourth mounting frame 33 is connected to the second gantry 31 through a second lifting mechanism 34. The third mounting frame 242 is also provided with an exhaust pipe (not shown) connected to the exhaust head 32.

[0077] After the battery BT has completed the removal of the glue nail J on the first positioning bracket 20, the conveyor line 1 transfers the restraint tray P to the second positioning bracket 30. Then, the second lifting mechanism 34 is activated to drop the vacuum head 32 to the glue nail J hole on the battery BT. At this time, the vacuum head 32 is adsorbed on the glue nail J hole. Next, the vacuum pipe evacuates the vacuum head 32 to generate a slight negative pressure in the vacuum head 32. Under the action of the slight negative pressure, the gas inside the battery BT enters the vacuum head 32, and the electrolyte is not extracted.

[0078] In another preferred embodiment of the present invention, Figure 3 and Figure 4 The conveyor line 1 includes a plurality of conveyor rollers 10 arranged at intervals. The first positioning bracket 20 and the second positioning bracket 30 are arranged at the gap or both ends of the conveyor rollers 10. The third lifting mechanism 50 and the fourth lifting mechanism 51 are respectively configured for the first positioning bracket 20 and the second positioning bracket 30 under the conveyor rollers 10. The third lifting mechanism 50 and the fourth lifting mechanism 51 are respectively used to drive the first positioning bracket 20 and the second positioning bracket 30 to move up and down.

[0079] Taking the nail pulling mechanism 2 as an example, when the restraint tray P needs to be driven to move, the third lifting mechanism 50 drives the first positioning bracket 20 to descend to the bottom of the conveying roller 10. When the restraint tray P is moved to the position, the third lifting mechanism 50 drives the first positioning bracket 20 to move up to lift the restraint tray P, and the restraint tray P is separated from the conveying roller 10 to wait for nail pulling or air extraction.

[0080] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
