Description

Technical Field

[0001] The present invention relates to the technical field of battery liquid injection, and particularly relates to a pre-pressing nail suction head automatic replacement mechanism and a pre-pressing nail suction device. Background Art

[0002] At present, battery liquid injection machines have been widely used in the market. As an indispensable part of the battery liquid injection process, the pre-pressing nail station has a crucial impact on the battery cell. Therefore, higher and higher requirements are imposed on its stability, reliability, and comprehensive functionality. There is a problem in the pre-pressing nail process of the existing battery liquid injection machine. Due to the characteristics of the electrolyte, it will change from a liquid state to a solid state in a short time. After the electrolyte crystallizes, it will block the suction nozzle, resulting in the inability of the suction nozzle to suck the glue nail. At this time, the equipment needs to be shut down and the suction nozzle needs to be replaced manually, resulting in low operation efficiency. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a pre-pressing nail suction head automatic replacement mechanism and a pre-pressing nail suction device, which can solve the problem of inconvenient replacement after the existing pre-pressing nail suction nozzle is blocked by electrolyte crystallization.

[0004] The technical solution adopted by the present invention to solve its technical problems is as follows: On the one hand, a pre-pressing nail suction head automatic replacement mechanism is provided, including a suction head, a suction component, and a replacement component;

[0005] The suction head includes a first magnetic attraction member and a suction nozzle, and the suction nozzle is used for adsorbing the pre-pressing nail;

[0006] The suction component includes a suction head body and a second magnetic attraction member installed on the suction head body, and the second magnetic attraction member is used for adsorbing the first magnetic attraction member;

[0007] The replacement component includes a mounting plate and a clamping plate arranged on the mounting plate. A plurality of the suction heads are placed on the mounting plate. The clamping plate is provided with a first through hole and a second through hole that communicate with each other. The first through hole is in clearance fit with the first magnetic attraction member, and the second through hole is in clearance fit with the second magnetic attraction member. Moreover, the cross-sectional area of the first magnetic attraction member is larger than the cross-sectional area of the second through hole.

[0008] As a further improvement of the above technical solution, a clamping jaw is further installed on the suction head body. The middle part of the clamping jaw is rotatably connected to the suction head body. The two ends of the clamping jaw are respectively a clamping end and a pressing end. The clamping end is provided with a hook portion that bends inward, and the pressing end is connected to the suction head body through a compression spring;

[0009] A pressing block is further installed on the mounting plate. When the second magnetic attraction member enters the second through hole from the first through hole, the pressing end abuts against the pressing block, so that the clamping jaw opens, and thus the clamping end is separated from the first magnetic attraction member.

[0010] As a further improvement of the above technical solution, a roller is rotatably connected to the pressing end, and the roller is used to abut against the pressing block; the clamping jaw 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 of the above technical solution, a slope is provided on the outer side of the hook portion. When the hook portion abuts against the first magnetic attraction member, the slope slides relative to the outer side of the first magnetic attraction member, so that the hook portion is pushed open and moves downward relative to the first magnetic attraction member.

[0012] As a further improvement of the above technical solution, the suction nozzle is conical, and the end with a larger cross-sectional area thereof is connected to the first magnetic attraction member; a plurality of third through holes are provided on the mounting plate, and the suction nozzle is in clearance fit with the third through holes, and the first magnetic attraction member is used to abut against the edge of the third through holes; a strip hole through which the hook portion can pass is provided around each of the third through holes, and the length direction of the strip hole is the same as the radial direction of the third through hole. When the suction head is placed on the mounting plate, the first magnetic attraction member covers a part of the strip hole.

[0013] As a further improvement of the above technical solution, a material receiving box is further included, and the material receiving box is located below the buckle plate and is communicated with the second through hole and the first through hole.

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

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

[0016] As a further improvement of the above technical solution, a manipulator is further included, and the manipulator is used to drive the suction head body to move in the horizontal direction and / or the vertical direction.

[0017] On the other hand, a pre-pressed nail suction device is provided, including a negative pressure member 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 communicates the suction nozzle and the negative pressure nozzle, and the negative pressure nozzle is used to be connected to the negative pressure member. The negative pressure member is used to provide a suction force for sucking the pre-pressed nails.

[0018] The beneficial effects of the present invention are as follows: When the nozzle is blocked by electrolyte crystallization, move the suction head body to drive the entire suction component closer to the buckle plate, pass the first magnetic component through the first through hole, so that the first magnetic component is located below the first through hole, and move the suction head body in the direction close to the second through hole, so that the first magnetic component is located below the second through hole. At this time, move upward, the first magnetic component abuts against the edge of the second through hole, and continue to move upward to separate the first magnetic component from the second magnetic component, and then the old nozzle automatically falls off the suction head body; then move the suction head body towards the position where the new nozzle exists on the mounting plate until the entire suction component is above the new nozzle, move the suction head body downward so that the second magnetic component adsorbs to the first magnetic component of the new nozzle, and finally move the suction head body upward to complete the automatic replacement of the old and new nozzles. The whole process does not require the equipment to stop and does not waste labor costs, solves the problem of inconvenient replacement of the pre-pressed nail nozzle, and improves the production efficiency of battery liquid injection.

[0030] The concept, specific structure and technical effects of the present invention will be clearly and completely described below in conjunction with the embodiments and the drawings, so as to fully understand the purpose, features and effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention. In addition, all connection / connection relationships involved in the patent do not simply refer to the direct connection of components, but refer to more excellent connection structures that can be formed by adding or reducing connection accessories according to specific implementation situations. For example, fixed connection / fixed installation can be selected from screw connection, bolt connection, pin connection, key connection, bonding, tenon and mortise connection, welding, riveting and other methods as needed. For example, detachable connection can be selected from screw connection, bolt connection, threaded connection, snap connection, tenon and mortise connection, magic tape connection and other methods as needed. The various technical features in the present invention can be combined with each other without conflict.

[0031] Please refer to Figure 1-2 , a preferred embodiment of the present invention provides a pre-pressed nail suction head automatic replacement mechanism, including a suction head 1, a suction component 2, a replacement component 3, a receiving box 4 and a manipulator (not shown in the figure). The suction head 1 is installed on the suction component 2 and is used for sucking pre-pressed nails. A number of spare suction heads 1 are placed on the replacement component 3. When the suction head 1 on the suction component 2 is blocked by electrolyte crystallization, the spare suction head 1 can be replaced through the replacement component 3. The manipulator is used to drive the suction head body 21 to move in the horizontal direction and / or the vertical direction to automatically move the suction head body 21 to the required position, further reducing the labor cost.

[0032] Specifically, please refer to Figure 2, the suction head 1 includes a first magnetic component 11 and a suction nozzle 12, and the suction nozzle 12 is used for adsorbing the pre-pressed nails; the suction component 2 includes a suction head body 21, and a clamping jaw 22 and a second magnetic component 23 both installed on the suction head body 21. The second magnetic component 23 is used for adsorbing the first magnetic component 11, and the clamping jaw 22 is used for clamping or loosening the suction head 1. The suction head 1 is doubly fixed by the magnetic attraction force between the clamping jaw 22 and the two magnetic components, effectively preventing the suction head 1 from falling off when sucking the pre-pressed nails.

[0033] Please refer to Figure 1 , the replacement component 3 includes a mounting plate 31, and a clamping plate 322 and a photoelectric sensor 33 arranged on the mounting plate 31. A number of suction heads 1 are placed on the mounting plate 31, and the photoelectric sensor 33 is used for detecting 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 optical signal to detect whether there is a suction head 1 between the two.

[0034] Please refer to Figure 1-3 , the clamping plate 322 is provided with a first through hole 323 and a second through hole 324 that communicate with each other. The first through hole 323 has a clearance fit with the first magnetic component 11, and the second through hole 324 has a clearance fit with the second magnetic component 23, and the cross-sectional area of the first magnetic component 11 is larger than the cross-sectional area of the second through hole 324. When the suction nozzle 12 is blocked by electrolyte crystallization, move the suction head body 21 to drive the entire suction component 2 to approach the clamping plate 322, pass the first magnetic component 11 through the first through hole 323, so that the first magnetic component 11 is located below the first through hole 323, and move the suction head body 21 in the direction close to the second through hole 324, so that the first magnetic component 11 is located below the second through hole 324. At this time, move upward, the first magnetic component 11 abuts against the edge of the second through hole 324, and continue to move upward, so that the first magnetic component 11 is separated from the second magnetic component 23, and then the old suction head automatically falls off from the suction head body; then move the suction head body 21 to the position where there is a new suction head on the mounting plate 31 until the entire suction component 2 is located above the new suction head, move the suction head body 21 downward, so that the second magnetic component 23 adsorbs the first magnetic component 11 of the new suction head, and finally move the suction head body 21 upward to complete the automatic replacement of the old and new suction heads. The whole process does not require the equipment to be shut down and does not waste labor costs, solves the problem of inconvenient replacement of the pre-pressed nail suction nozzle, and improves the production efficiency of battery liquid injection.

[0035] More specifically, please refer to Figure 2, a jaw 22 is further installed on the suction head main body 21. The middle part of the jaw 22 is rotatably connected to the suction head main body 21. The two ends of the jaw 22 are respectively a clamping end 221 and a pressing end 222. An inwardly bent hook portion 223 is provided at the clamping end 221. A compression spring 224 is connected between the pressing end 222 and the suction head main body 21. The compression spring 224 is used to provide an elastic force to enable the hook portion 223 to hook the suction head 1. In the natural state, the compression spring 224 is pressed between the pressing end 222 and the suction head main body 21, and its elastic force causes the clamping end 221 to move towards the suction head main body 21, and the hook portion 223 hooks the lower side of the first magnetic attraction member 11, further pressing the first magnetic attraction member 11 against the second magnetic attraction member 23. Press the pressing end 222, the compression spring 224 is further compressed, and the hook portion 223 releases the first magnetic attraction member 11. Release the pressing end 222, the compression spring 224 returns, driving the hook portion 223 to hook the first magnetic attraction member 11, thereby realizing the clamping of the suction head 1 by the jaw 22. The structure is simple and easy to operate.

[0036] In this embodiment, the jaw 22 includes two arms 225 connected at the ends, and the two arms 225 are connected in a V shape. Two opposite support ears 226 are provided on the suction head main body 21. The connection part of the two arms 225 is connected to the two support ears 226 through a rotating shaft 227, which is convenient for the jaw 22 to rotate relative to the suction head main body 21, so as to realize the clamping of the suction head 1.

[0037] Please refer to Figure 1 and Figure 3 , a pressing block 321 is further installed on the mounting plate 31. The clamping plate 322 is located on one side of the pressing block 321. When the second magnetic attraction member 23 enters the second through hole 324 from the first through hole 323, the pressing end 222 abuts against the pressing block 321, so that the jaw 22 opens, and thus the clamping end 221 is separated from the first magnetic attraction 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 attraction member 11 is located below the first through hole 323. Then continue to move the suction assembly 2 forward so that the first magnetic attraction member 11 is located below the second through hole 324, and the pressing end 222 impacts the pressing block 321. The compression spring 224 contracts, and the hook portion 223 releases the first magnetic attraction member 11. Then move the suction head main body 21 upward so that the first magnetic attraction member 11 abuts against the edge of the second through hole 324 and separates the first magnetic attraction member 11 from the second magnetic attraction member 23. The old suction head drops automatically. The whole process is easy to operate and is beneficial to improving production efficiency.

[0038] Please refer to Figure 3, in 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 arrangement of the roller 228 is beneficial to reducing friction and the wear degree of the pressing block 321, and the roller 228 can effectively absorb and disperse the impact force to further protect the pressing block 321.

[0039] Please refer to Figure 1 , a clearance hole 325 is extended and provided on one side of the second through hole 324 close to the pressing block 321. The clearance hole 325 is used to accommodate the support arm 225, and the clearance hole 325 is in clearance fit with the support arm 225 to facilitate the rotation of the support arm 225.

[0040] Please refer to Figure 7 , the receiving box 4 is located below the buckling plate 322 and is communicated with the second through hole 324 and the first through hole 323. After the old suction head is separated from the suction head main body 21, it can automatically fall into the receiving box 4, which is convenient for the storage of the old suction head and subsequent centralized cleaning treatment of the old suction head.

[0041] Specifically, the receiving box 4 is arranged in the support frame 42 in a push-pull manner, and the mounting plate 31 is arranged above the support frame 42. A handle 43 is arranged on one side of the receiving box 4. The arrangement of the handle 43 makes the receiving box 4 easier to carry, especially when it is full of old suction heads.

[0042] In this embodiment, an inclined plate 41 is arranged in the receiving box 4. The upper end of the inclined plate 41 is located below the second through hole 324. The old suction head falls on the inclined plate 41 first and then slides along the inclined plate 41 to the bottom of the receiving box 4. The inclined plate 41 reduces the falling height of the old suction head and can play a buffering role to prevent the old suction head from being damaged.

[0043] Please refer to Figure 2 , the suction nozzle 12 is conical, and the end with a larger cross-sectional area thereof is connected to the first magnetic attraction member 11; Please refer to Figure 1 , a plurality of third through holes 311 are arranged on the mounting plate 31. The suction nozzle 12 is in clearance fit with the third through holes 311. The first magnetic attraction member 11 is used to abut against the edge of the third through holes 311. When the suction head 1 is placed on the mounting plate 31, the first magnetic attraction member 11 is located above the third through holes 311 and abuts against the mounting plate 31, and the suction nozzle 12 is located below the third through holes 311, which is convenient for the taking and placing of the suction head 1. After the suction head 1 is used up, it can be quickly replenished on the mounting plate 31 manually.

[0044] Please refer to Figure 1 and Figure 5, in this embodiment, strip-shaped holes 312 through which the hook portions 223 can pass are provided around each of the third through-holes 311. The length direction of the strip-shaped holes 312 is the same as the radial direction of the third through-holes 311. When the suction head 1 is placed on the mounting plate 31, the first magnetic member 11 covers a part of the strip-shaped holes 312. Please refer to Figure 4 , a slope 229 is provided on the outer side of the hook portion 223. When the hook portion 223 abuts against the first magnetic member 11, the slope 229 slides relative to the outer side of the first magnetic member 11, so that the hook portion 223 is pushed open and moves downward relative to the first magnetic member 11. When installing a new suction head, the position of the suction head 1 on the mounting plate 31 is sensed and fed back by the photoelectric sensor 33, and the suction head main body 21 is moved towards the position where the suction head 1 exists and moved downward, so that the slope 229 abuts against the outer side of the first magnetic member 11, and the slope 229 slides relative to the outer side of the first magnetic member 11, the hook portion 223 is automatically pushed open, and continue to move downward. Please refer to Figure 5 , so that the hook portion 223 enters the strip-shaped hole 312 and hooks under the first magnetic member 11. At the same time, the first magnetic member 11 and the second magnetic member 23 are adsorbed together to complete the installation of the new suction head.

[0045] A preferred embodiment of the present invention further provides a pre-pressed nail suction device, including a negative pressure member and the pre-pressed nail suction head automatic replacement mechanism of the above embodiment. Please refer to Figure 6 , the suction head main body 21 is provided with a negative pressure channel 211 and a negative pressure nozzle 212. The negative pressure channel 211 communicates the suction nozzle 12 and the negative pressure nozzle 212. The negative pressure nozzle 212 is used to connect with the negative pressure member, and the negative pressure member is used to provide the suction force for sucking the pre-pressed nail. The negative pressure member can be a vacuum pump or a negative pressure generator, etc. After the suction nozzle 12 adsorbs the pre-pressed nail, a pre-pressure is applied to the pre-pressed nail to ensure the accuracy of its positioning and fixing. When the suction nozzle 12 is blocked by the electrolyte, the automatic replacement of the old and new suction heads can be completed through this pre-pressed nail suction head automatic replacement mechanism. The whole process does not require the equipment to stop and does not waste labor costs, solves the problem of inconvenient replacement of the pre-pressed nail suction nozzle, and improves the production efficiency of battery liquid injection.
