Description

Technical Field

[0001] This utility model relates to the field of battery liquid injection technology, specifically to an automatic replacement mechanism for a pre-compression nail suction head and a pre-compression nail suction device. Background Technology

[0002] Battery electrolyte filling machines are now widely used in the market. The pre-pressing nail station, as an indispensable part of the battery electrolyte filling process, has a crucial impact on the battery cell, thus requiring increasingly higher standards for its stability, reliability, and comprehensive functionality. However, the pre-pressing nail process in existing battery electrolyte filling machines has a problem: due to the characteristics of the electrolyte, it changes from liquid to solid in a short time. After crystallization, the electrolyte can clog the suction nozzle, preventing it from picking up the glue nails. This necessitates stopping the machine and manually replacing the nozzle, resulting in low operational efficiency. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides an automatic replacement mechanism for pre-compression nail suction head and a pre-compression nail suction device, which can solve the problem of inconvenient replacement of existing pre-compression nail suction nozzles after they are blocked by electrolyte crystallization.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: On the one hand, it provides an automatic replacement mechanism for a pre-pressed nail suction head, including a suction head, a suction component, and a replacement component;

[0005] The suction head includes a first magnetic suction element and a suction nozzle, the suction nozzle being used to adsorb pre-compressed nails;

[0006] The suction assembly includes a suction head body and a second magnetic suction member mounted on the suction head body, wherein the second magnetic suction member is used to attract the first magnetic suction member;

[0007] The replacement component includes a mounting plate and a clip plate disposed on the mounting plate. A plurality of suction heads are placed on the mounting plate. The clip plate is provided with a first through hole and a second through hole that are interconnected. The first through hole is clearance-fitted with the first magnetic suction member, and the second through hole is clearance-fitted with the second magnetic suction member. The cross-sectional area of ​​the first magnetic suction member is larger than the cross-sectional area of ​​the second through hole.

[0008] As a further improvement to the above technical solution, the suction head body is also equipped with a gripper, the middle part of which is rotatably connected to the suction head body, and the two ends of the gripper are a gripping end and a pressing end, respectively. The gripping end is provided with an inwardly bent hook, and the pressing end is connected to the suction head body by a compression spring.

[0009] The mounting plate is also equipped with a pressure block. When the second magnetic suction member enters the second through hole from the first through hole, the pressing end abuts against the pressure block, so that the gripper opens and the gripping end separates from the first magnetic suction member.

[0010] As a further improvement to the above technical solution, the pressing end is rotatably connected to a roller, which is used to abut against the pressing block; the gripper is rotatably connected to the suction head body through a rotating shaft, and the axial direction of the rotating shaft is parallel to the axial direction of the roller.

[0011] As a further improvement to the above technical solution, the outer side of the hook is provided with a slope. When the hook abuts against the first magnetic member, the slope slides relative to the outer side of the first magnetic member, so that the hook is pushed open and moves downward relative to the first magnetic member.

[0012] As a further improvement to the above technical solution, the suction nozzle is conical, and its end with the larger cross-sectional area is connected to the first magnetic suction member; the mounting plate is provided with a plurality of third through holes, the suction nozzle is clearance-fitted with the third through holes, and the first magnetic suction member is used to abut against the edge of the third through holes; each of the third through holes is surrounded by a strip hole that allows the hook to pass through, the length direction of the strip hole is the same as the radial direction of the third through hole, and when the suction head is placed on the mounting plate, the first magnetic suction member covers part of the strip hole.

[0013] As a further improvement to the above technical solution, a receiving box is also included, which is located below the buckle plate and communicates with the second through hole and the first through hole.

[0014] As a further improvement to the above technical solution, the receiving box is provided with an inclined plate, the upper end of which is located below the second through hole.

[0015] As a further improvement to the above technical solution, a photoelectric sensor is also installed on the mounting plate, and the suction head is located between the transmitting end and the receiving end of the photoelectric sensor.

[0016] As a further improvement to the above technical solution, a robotic arm is also included, which is used to drive the suction head body to move in the horizontal and / or vertical directions.

[0017] On the other hand, a pre-pressed nail suction device is provided, including a negative pressure component and the aforementioned pre-pressed nail suction head automatic replacement mechanism. The suction head body is provided with a negative pressure channel and a negative pressure nozzle. The negative pressure channel connects the suction nozzle and the negative pressure nozzle. The negative pressure nozzle is used to connect with the negative pressure component. The negative pressure component is used to provide suction force for suctioning pre-pressed nails.

[0018] The beneficial effects of this invention are as follows: When the suction nozzle is blocked by electrolyte crystals, the suction head body is moved to bring the entire suction assembly closer to the mounting plate, allowing the first magnetic suction member to pass through the first through hole, placing it below the first through hole. The suction head body is then moved towards the second through hole, placing the first magnetic suction member below the second through hole. Moving upwards, the first magnetic suction member abuts against the edge of the second through hole. Continuing to move upwards, the first and second magnetic suction members separate, causing the old suction head to automatically detach from the suction head body. Then, the suction head body is moved towards the location of the new suction head on the mounting plate until the entire suction assembly is above the new suction head. Moving downwards, the suction head body attracts the second magnetic suction member to the first magnetic suction member of the new suction head. Finally, the suction head body is moved upwards, completing the automatic replacement of the old and new suction heads. The entire process does not require stopping the equipment and saves labor costs, solving the problem of inconvenient replacement of pre-compression nail suction nozzles and improving the production efficiency of battery electrolyte filling.

[0030] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / connections involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. For example, fixed connections / fixed installations can use screw connections, bolt connections, pin connections, key connections, adhesive connections, mortise and tenon connections, welding, riveting, etc., as needed. For detachable connections, screw connections, bolt connections, threaded connections, snap-fit ​​connections, mortise and tenon connections, Velcro connections, etc., can be used as needed. The various technical features in this utility model can be combined interactively without contradicting each other.

[0031] Please see Figure 1-2 The preferred embodiment of this utility model provides an automatic replacement mechanism for pre-compression nail suction heads, including a suction head 1, a suction assembly 2, a replacement assembly 3, a receiving box 4, and a robotic arm (not shown in the figure). The suction head 1 is mounted on the suction assembly 2 and is used to suction pre-compression nails. Several spare suction heads 1 are placed on the replacement assembly 3. When the suction head 1 on the suction assembly 2 is blocked by electrolyte crystallization, the spare suction head 1 can be replaced by the replacement assembly 3. The robotic arm is used to drive the suction head body 21 to move in the horizontal and / or vertical directions to automatically move the suction head body 21 to the required position, further reducing labor costs.

[0032] For details, please see Figure 2The suction head 1 includes a first magnetic suction member 11 and a suction nozzle 12. The suction nozzle 12 is used to adsorb pre-compressed nails. The suction assembly 2 includes a suction head body 21 and a gripper 22 and a second magnetic suction member 23, both mounted on the suction head body 21. The second magnetic suction member 23 is used to adsorb the first magnetic suction member 11. The gripper 22 is used to clamp or release the suction head 1. The suction head 1 is doubly fixed by the magnetic attraction between the gripper 22 and the two magnetic suction members, which effectively prevents the suction head 1 from falling off when adsorbing pre-compressed nails.

[0033] Please see Figure 1 The replacement component 3 includes a mounting plate 31, a clip plate 322 and a photoelectric sensor 33 disposed on the mounting plate 31. Several suction heads 1 are placed on the mounting plate 31. The photoelectric sensor 33 is used to detect the position of the suction head 1. Specifically, the suction head 1 is located between the transmitting end and the receiving end of the photoelectric sensor 33. The transmitting end emits a light beam 331 to the receiving end, and the receiving end receives the reflected or transmitted light signal to detect whether there is a suction head 1 between the two.

[0034] Please see Figure 1-3 The buckle plate 322 is provided with a first through hole 323 and a second through hole 324 that are interconnected. The first through hole 323 is in clearance fit with the first magnetic attractor 11, and the second through hole 324 is in clearance fit with the second magnetic attractor 23. The cross-sectional area of ​​the first magnetic attractor 11 is larger than the cross-sectional area of ​​the second through hole 324. When the suction nozzle 12 is blocked by electrolyte crystals, the suction head body 21 is moved to bring the entire suction assembly 2 closer to the buckle plate 322, so that the first magnetic suction member 11 passes through the first through hole 323 and is positioned below the first through hole 323. The suction head body 21 is then moved towards the second through hole 324, so that the first magnetic suction member 11 is positioned below the second through hole 324. At this time, it is moved upward, and the first magnetic suction member 11 abuts against the edge of the second through hole 324. It continues to move upward, so that the first magnetic suction member 11 separates from the second magnetic suction member 23, and the old suction head automatically falls off the suction head body. Then, the suction head body 21 is moved towards the position where the new suction head exists on the mounting plate 31 until the entire suction assembly 2 is above the new suction head. The suction head body 21 is moved downward, so that the second magnetic suction member 23 attracts the first magnetic suction member 11 of the new suction head. Finally, the suction head body 21 is moved upward to complete the automatic replacement of the old and new suction heads. The entire process does not require stopping the equipment and does not waste labor costs, solving the problem of inconvenient replacement of pre-compression nozzles and improving the production efficiency of battery electrolyte injection.

[0035] For more details, please see Figure 2The suction head body 21 is also equipped with a gripper 22. The middle part of the gripper 22 is rotatably connected to the suction head body 21. The two ends of the gripper 22 are a gripping end 221 and a pressing end 222, respectively. The gripping end 221 is provided with an inwardly bent hook 223. The pressing end 222 is connected to the suction head body 21 by a compression spring 224. The compression spring 224 is used to provide elastic force so that the hook 223 hooks the suction head 1. In the natural state, the compression spring 224 is pressed between the pressing end 222 and the suction head body 21. Its elastic force causes the gripping end 221 to move towards the suction head body 21, and the hook 223 hooks the lower side of the first magnetic suction member 11, further pressing the first magnetic suction member 11 onto the second magnetic suction member 23. Pressing the pressing end 222 further compresses the compression spring 224, causing the hook 223 to release the first magnetic suction member 11. Releasing the pressing end 222 causes the compression spring 224 to return, driving the hook 223 to hook the first magnetic suction member 11, thereby realizing the gripper 22 to clamp the suction head 1. The structure is simple and easy to operate.

[0036] In this embodiment, the gripper 22 includes two arms 225 connected at the ends, and the two arms 225 are connected in a V-shape. The suction head body 21 is provided with two oppositely arranged ears 226. The connection between the two arms 225 is connected to the two ears 226 through a rotating shaft 227, which facilitates the gripper 22 to rotate relative to the suction head body 21, thereby realizing the gripping of the suction head 1.

[0037] Please see Figure 1 and Figure 3 The mounting plate 31 is also equipped with a pressure block 321, and the buckle plate 322 is located on one side of the pressure block 321. When the second magnetic suction member 23 enters the second through hole 324 from the first through hole 323, the pressing end 222 abuts against the pressure block 321 so that the claw 22 opens, thereby separating the clamping end 221 from the first magnetic suction member 11. When removing the old suction head, first move the entire suction assembly 2 directly above the first through hole 323, and place the old suction head into the first through hole 323, so that the first magnetic suction member 11 is below the first through hole 323. Then continue to move the suction assembly 2 forward, so that the first magnetic suction member 11 is below the second through hole 324, and the pressing end 222 impacts the pressure block 321, the compression spring 224 contracts, the hook 223 releases the first magnetic suction member 11, and then move the suction head body 21 upward, so that the first magnetic suction member 11 abuts against the edge of the second through hole 324, and the first magnetic suction member 11 separates from the second magnetic suction member 23. The old suction head falls off automatically. The whole process is easy to operate and helps to improve production efficiency.

[0038] Please see Figure 3In this embodiment, a roller 228 is rotatably connected to the pressing end 222. The roller 228 is used to abut against the pressing block 321, and the axial direction of the rotating shaft 227 is parallel to the axial direction of the roller 228. The roller 228 helps to reduce friction and reduce the wear of the pressing block 321. Furthermore, the roller 228 can effectively absorb and disperse impact force, further protecting the pressing block 321.

[0039] Please see Figure 1 The second through hole 324 extends to the side near the pressure block 321 and is provided with a clearance hole 325. The clearance hole 325 is used to accommodate the support arm 225, and the clearance hole 325 is clearance-fitted with the support arm 225 to facilitate the rotation of the support arm 225.

[0040] Please see Figure 7 The receiving box 4 is located below the buckle plate 322 and is connected to the second through hole 324 and the first through hole 323. After the old nozzle is separated from the nozzle body 21, it can automatically fall into the receiving box 4, which facilitates the storage of the old nozzle and makes it easier to clean and process the old nozzle in a centralized manner later.

[0041] Specifically, the receiving box 4 is installed inside the support frame 42 by a push-pull mechanism, and the mounting plate 31 is installed above the support frame 42. A handle 43 is provided on one side of the receiving box 4, which makes the receiving box 4 easier to move, especially when it is full of old suction heads.

[0042] In this embodiment, a ramp 41 is provided inside the receiving box 4. The upper end of the ramp 41 is located below the second through hole 324. The old suction head falls onto the ramp 41 immediately and then slides along the ramp 41 to the bottom of the receiving box 4. The ramp 41 reduces the falling height of the old suction head and can play a buffering role to prevent damage to the old suction head.

[0043] Please see Figure 2 The suction nozzle 12 is conical, and its end with the larger cross-sectional area is connected to the first magnetic suction element 11; please refer to Figure 1 The mounting plate 31 is provided with several third through holes 311. The suction nozzle 12 is fitted with the third through hole 311 with a clearance. The first magnetic suction member 11 is used to abut against the edge of the third through hole 311. When the suction head 1 is placed on the mounting plate 31, the first magnetic suction member 11 is located above the third through hole 311 and abuts against the mounting plate 31. The suction nozzle 12 is located below the third through hole 311, which facilitates the removal and placement of the suction head 1. After the suction head 1 is used up, it can be quickly replenished by manpower on the mounting plate 31.

[0044] Please see Figure 1 and Figure 5In this embodiment, each third through hole 311 is surrounded by a strip-shaped hole 312 that allows the hook portion 223 to pass through. The length direction of the strip-shaped hole 312 is the same as the radial direction of the third through hole 311. When the suction head 1 is placed on the mounting plate 31, the first magnetic suction member 11 covers part of the strip-shaped hole 312. Please refer to Figure 4 The hook 223 has an inclined surface 229 on its outer side. When the hook 223 abuts against the first magnetic suction member 11, the inclined surface 229 slides relative to the outer side of the first magnetic suction member 11, so that the hook 223 is pushed open and moves downward relative to the first magnetic suction member 11. When installing a new suction head, the photoelectric sensor 33 senses and provides feedback on the position of the suction head 1 on the mounting plate 31, and moves the suction head body 21 towards the position where the suction head 1 is located, moving downward so that the inclined surface 229 abuts against the outer side of the first magnetic suction member 11, and the inclined surface 229 slides relative to the outer side of the first magnetic suction member 11, the hook 223 is automatically pushed open, and it continues to move downward. Please refer to [link to relevant documentation]. Figure 5 This allows the hook 223 to enter the strip hole 312 and hook below the first magnetic suction member 11. At the same time, the first magnetic suction member 11 and the second magnetic suction member 23 are attracted together, completing the installation of the new suction head.

[0045] A preferred embodiment of this utility model also provides a pre-compression nail suction device, including a negative pressure component and an automatic replacement mechanism for the pre-compression nail suction head described in the above embodiment. Please refer to [link to relevant documentation]. Figure 6 The suction head body 21 is equipped with a negative pressure channel 211 and a negative pressure nozzle 212. The negative pressure channel 211 connects the suction nozzle 12 and the negative pressure nozzle 212. The negative pressure nozzle 212 is used to connect to a negative pressure component, which provides suction for picking up the pre-compression nail. The negative pressure component can be a vacuum pump or a negative pressure generator, etc. After the suction nozzle 12 picks up the pre-compression nail, a pre-pressure is applied to the pre-compression nail to ensure its accurate positioning and fixation. When the suction nozzle 12 is blocked by electrolyte, the automatic replacement mechanism for the pre-compression nail suction head can automatically replace the old suction head with a new one. The whole process does not require stopping the equipment and does not waste labor costs, solving the problem of inconvenient replacement of the pre-compression nail suction head and improving the production efficiency of battery electrolyte filling.

[0046] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
