Description

[0002] In the process of assembling a battery, the pulling of glue nails and the extraction of gas are two important procedures. The pulling of glue nails is usually to facilitate the discharge or introduction of gas in the battery, to ensure that the air tightness and safety of the battery meet the requirements, and the extraction of gas is to remove harmful gas remaining in the battery, to avoid affecting the performance of the battery or causing safety hazards.

[0003] In the prior art, the nail pulling and air extraction procedures are generally carried out independently, and nail pulling equipment and air extraction equipment need to be separately arranged.

In addition, the battery needs to be transferred multiple times between the nail pulling and air extraction procedures, which easily affects the production efficiency.

[0039] To illustrate the technical content, structural features, objectives, and effects of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0040] This embodiment discloses a battery adhesive nail detachment and venting device that integrates nail removal and air extraction functions, aiming to solve the problems of dispersed equipment, complex processes, and insufficient pollution control in existing technologies. Figures 1 to 4 The device includes a first positioning bracket 20, a second positioning bracket 30, a conveyor 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 to place the restraint tray P containing the battery BT.

[0042] The conveyor line 1 is used to move the restraint tray P between the first positioning bracket 20 and the second positioning bracket 30.

[0043] like Figures 5 to 9 The nail removal mechanism 2 includes a first gantry 21 mounted above the first positioning bracket 20 and a robotic arm 22 mounted on the first gantry 21 that can move up and down relative to the restraint tray P. The robotic arm 22 is used to remove the adhesive nails J on the battery BT inside the restraint tray P.

[0044] like Figure 10 and Figure 11 The robotic arm 22 is fitted with a protective cover 23. The protective cover 23 includes a first connecting end 230 and a second connecting end 231 located at both ends, and a cover body 232 located between the first connecting end 230 and the second connecting end 231. The length of the cover body 232 can be extended or retracted. In this embodiment, the protective cover 23 is an accordion cover, made of soft silicone, rubber, polyurethane resin, coated soft rubber, etc., and is integrally molded using 3D printing technology.

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

[0046] As Figure 2 and Figure 3 , the suction mechanism 3 includes a second gantry 31 located above the second positioning support 30 and a suction head 32 arranged on the second gantry 31 and capable of lifting the tray P relative to the tray P. The suction head 32 is used for butt joint with the glue nail J hole on the battery BT, so as to extract the gas in the battery BT.

[0047] For the above-mentioned battery glue nail disengaging and exhausting device, specifically, through the parallel arrangement of the first positioning support 20 and the second positioning support 30, the conveying line 1 is matched to realize efficient transfer of the restrained tray P with the battery BT between the nail pulling and gas extraction processes. The nail pulling mechanism 2 adopts the manipulator 22 arranged on the first gantry 21, and the manipulator 22 can lift the restrained tray P in the vertical direction to accurately pull out the glue nail J on the battery BT in the tray. In this process, the protective cover 23 outside the manipulator 22 is effectively protected by the sealing connection design of the nail pulling process, and the cover body 232 has the function of stretching and retracting, which can adapt to the movement of the manipulator 22. The protective cover 23 not only prevents dust and debris generated during nail pulling from entering the battery BT body, but also effectively collects and discharges the escaping gas through the sealing connection and exhaust port 234 design, avoiding pollution of the production environment.

[0048] At the same time, the suction mechanism 3 realizes precise butt joint with the glue nail J hole of the battery BT through the suction head 32 located on the second gantry 31, and quickly extracts the gas in the battery BT after the nail pulling is completed.

[0049] The battery glue nail disengaging and exhausting device in the embodiment integrates the nail pulling and gas extraction processes on the same production line, which significantly simplifies the process flow and reduces the equipment occupation space and transfer cost.

[0050] Through the design of the protective cover 23, the dust pollution and gas emission problems in the nail pulling and gas extraction processes are also effectively solved, which not only guarantees the air tightness and performance stability of the battery BT, but also significantly improves the safety and cleanliness of the production environment, which has important application value.

[0051] On the other hand, as Figure 10 and Figure 11 , the first connecting end 230 is also provided with an air inlet 233 in communication with the internal space of the protective cover 23.

[0052] Before the mechanical arm 22 performs the nail pulling action after the second connecting end 231 of the protective cover 23 abuts against the battery BT, the protective cover 23 is filled with air through the air inlet 233, so that the air pressure in the protective cover 23 is equivalent to the internal pressure of the battery BT, thereby avoiding the electrolyte in the battery BT from being sprayed due to the excessively low air pressure in the protective cover 23.

[0053] On the other hand, as Figures 6 to 9 , the nail pulling mechanism 2 further comprises a first mounting frame 240 and a second mounting frame 241, the first mounting frame 240 is slidably connected with the first gantry 21 through a sliding mechanism 25, the second mounting frame 241 is connected with the first mounting frame 240 through a first lifting mechanism 26, and the mechanical arm 22 is mounted on the second mounting frame 241. The sliding mechanism 25 is used to drive the first mounting frame 240 to move along the first axis, so that the mechanical arm 22 can reciprocate on both sides of the restraint tray P, thereby performing the nail pulling work on the two rows of batteries BT on both sides of the restraint tray P respectively. Specifically, the sliding mechanism 25 comprises a driven sliding rail 251 and a driving sliding rail 250 with a sliding driver which are oppositely arranged, and the two ends of the first mounting frame 240 are connected with the driving sliding rail 250 and the driven sliding rail 251 respectively, so that the first mounting frame 240 is driven by the sliding driver on the driving sliding rail 250 to reciprocate on both sides of the restraint tray P.

[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 mechanical arm 22 approaches or moves away from the glue nails J on the battery BT.

[0055] More specifically, the first lifting mechanism 26 comprises a guide rod 260 and a first lifting driver 261. One end of the guide rod 260 is fixedly connected with the second mounting frame 241, the other end of the guide rod 260 penetrates through the first mounting frame 240 upwardly, 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, the driving end of the first lifting driver 261 is connected with the second mounting frame 241, and 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 the embodiment can be a linear motion driving device such as a pneumatic cylinder or a motor.

[0056] On the other hand, referring again to Figure 10 and Figure 11 , the mechanical arm 22 comprises two oppositely arranged clamping jaws 220, and the clamping jaws 220 are controlled to approach or move away from each other to achieve the work of grabbing or releasing the glue nails J.

[0057] For this purpose, as Figure 8 , Figure 9 and Figure 12The pulling mechanism 2 further comprises a third mounting frame 242 located at the bottom of the second mounting frame 241 and connected with the second mounting frame 241, and the bottom of the third mounting frame 242 is provided with a first linkage rod 270 and a second linkage rod 271. The first linkage rod 270 and the second linkage rod 271 are in sliding connection with 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 with the first linkage rod 270, and the other of the two clamping jaws 220 is connected with the second linkage rod 271.

[0058] The first mounting frame 241 is provided with a first clamping jaw driver 272 connected with the first linkage rod 270 and a second clamping jaw driver 273 connected with the second linkage rod 271, and 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 the closed state, the clamping action is realized, and when the two clamping jaws 220 are in the open state, the releasing action is realized.

[0059] On the other hand, as Figure 8 , Figure 9 and Figure 13 , one side of the mechanical arm 22 is also provided with a pressing rod 280 in parallel, the pressing rod 280 is connected with a connecting seat 281 extending outward from the second mounting frame 241 through a connecting rod 282, the connecting rod 282 is sleeved with an elastic element 283, one end of the elastic element 283 abuts against the pressing rod 280, and the other end of the elastic element 283 abuts against the connecting seat 281.

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

[0061] In this embodiment, the elastic element 283 is always in a compressed state from the time when the mechanical arm 22 contacts the glue nail J to the time when the glue nail J is pulled out, so that the pressing rod 280 is always pressed on the battery BT, avoiding that the mechanical arm 22 pulls out the battery BT from the restraint tray P.

[0062] Specifically, the pressing rod 280 is embedded with a connecting shaft 284, and one end of the connecting rod 282 close to the pressing rod 280 is provided with a connecting hole 285 matched with the connecting shaft 284. Based on the connecting hole 285, the pressing 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, as Figure 6The first portal frame 21 is further provided with a receiving box 4 on one side, which is used to receive the glue nail J pulled out by the mechanical hand 22.

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

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

[0066] 2. The sliding mechanism 25 on the first portal frame 21 is started to drive the first mounting bracket 240 to move to the target position.

[0067] 3. The first lifting driver 261 is started to drive the second mounting bracket 241 and the third mounting bracket 242 to move downward until the mechanical hand 22 contacts the glue nail J. During the downward movement, the pressing rod 280 first abuts against the edge of the battery BT, and the pressing rod 280 moves upward by 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 connecting end 231 of the protective cover 23 contacts the part around the glue nail J on the battery BT body, the second connecting end 231 is attached to the battery BT to cover the position of the glue nail J in the protective cover 23. With the further downward movement of the mechanical hand 22, the cover body 232 of the protective cover 23 is in a compressed state.

[0069] 4. Air is introduced into the protective cover 23 through the air inlet 233 to avoid the electrolyte from being sprayed due to the excessive pressure difference between the inside and outside of the battery BT after the glue nail J is pulled out.

[0070] 5. The first jaw driver 272 and the second jaw driver 273 are actuated to drive the first linkage rod 270 and the second linkage rod 271 to act, and then drive the two jaws 220 constituting the mechanical hand 22 to move close to each other to clamp the glue nail J.

[0071] 6. The first lifting driver 261 is actuated to drive the second mounting bracket 241 and the third mounting bracket 242 to move upward by a distance (for example, 5 mm) to drive the mechanical hand 22 to move upward, 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 glue nail J is pulled out, the high-pressure gas generated in the battery BT escapes into the protective cover 23, and at this time, the gas in the protective cover 23 is exhausted through the exhaust port 234.

[0073] 8. The first lifting driver 261 is actuated to drive the second mounting bracket 241 and the third mounting bracket 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 mechanical arm 22 to the position where the receiving box 4 is located, so as to release the glue nails J on the mechanical arm 22, and the glue nails J automatically fall into the receiving box 4.

[0075] 10. The sliding mechanism 25 drives the mechanical arm 22 to reset, so as to be accurate for the next work.

[0076] On the other hand, as shown in Figure 14 and Figure 15 , the fourth mounting frame 33 is arranged on the second gantry 31, the suction head 32 is arranged on the fourth mounting frame 33, the fourth mounting frame 33 is connected with the second gantry 31 through the second lifting mechanism 34, and the fourth mounting frame 33 is further provided with a suction pipe (not shown) connected with the suction head 32.

[0077] When the battery BT completes the work of pulling out the glue nails J on the first positioning support 20, the conveying line 1 transfers the restraint tray P to the second positioning support 30. Then, the second lifting mechanism 34 is started to lower the suction head 32 to the glue nail J hole on the battery BT, at this time, the suction head 32 is adsorbed on the glue nail J hole. Then, the suction pipe suctions the suction head 32 to generate a micro negative pressure in the suction head 32, under the action of the micro negative pressure, the gas in the battery BT enters the suction head 32, and the electrolyte cannot be sucked out.

[0078] In another preferred embodiment of the present application, as shown in Figure 3 and Figure 4 , the conveying line 1 comprises a plurality of conveying rollers 10 arranged at intervals. The first positioning support 20 and the second positioning support 30 are arranged at the gap or both ends of the conveying rollers 10, and the first positioning support 20 and the second positioning support 30 are respectively configured with corresponding third lifting mechanisms 50 and fourth lifting mechanisms 51 below the conveying rollers 10, and the third lifting mechanisms 50 and the fourth lifting mechanisms 51 are respectively used to drive the first positioning support 20 and the second positioning support 30 to move up and down.

[0079] Taking the nail pulling mechanism 2 as an example, when it is needed to drive the restraint tray P to move, the third lifting mechanism 50 drives the first positioning support 20 to descend to the lower side of the conveying roller 10. When the restraint tray P is moved to the position, the third lifting mechanism 50 drives the first positioning support 20 to move up to support the restraint tray P, and the restraint tray P is separated from the conveying roller 10, and waits for the work of pulling out the nails or suction.

[0080] The above only discloses the preferred embodiments of the present application, and of course cannot limit the scope of the rights of the present application, so the equivalent changes made according to the patent application scope of the present application still belong to the scope covered by the present application.
