Description

Technical Field

[0001] The utility model relates to the field of battery formation equipment, in particular to a nozzle disassembly tool. Background Art

[0002] During the production process of lithium battery cells, it is necessary to perform negative pressure formation on the lithium battery cells. During the negative pressure formation process, the battery needs to be pumped with negative pressure. The industry often uses a negative pressure module, that is, a negative pressure air path is used to fit tightly with the battery's liquid filling port through a corrosion-resistant rubber nozzle to avoid air leakage, so as to achieve the negative pressure conditions required for negative pressure formation.

[0003] However, the life of the rubber negative pressure nozzle is limited and needs to be replaced frequently. In order to facilitate the removal of the nozzle and improve the efficiency of nozzle removal, the nozzles in the industry are basically inserted into the end of a smooth metal rod. When replacement is required, the nozzle only needs to be pulled out along the axial direction of the metal rod and then a new nozzle can be inserted back into the metal rod.

[0004] In the prior art, the nozzle disassembly tool utilizes a motor to drive a pair of jaws to clamp the nozzle, and then utilizes a lifting motor to pull it out along the axial direction of a metal rod. When removing multiple nozzles on the negative pressure module, a single jaw needs to be used to pull them out one by one, which is inefficient. On the other hand, using multiple jaws to simultaneously pull out multiple nozzles has a more complicated structure and high cost. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the utility model provides a nozzle disassembly tool, which uses a purely mechanical structure to replace the motor clamping claw assembly for clamping the nozzle, and uses an electromagnet to replace the lifting motor assembly for pulling out the nozzle, thereby effectively reducing the manufacturing cost of the tool, having a simple structure and being easy to operate.

For example, fixed connection / fixed installation can be selected according to the needs of screw connection, bolt connection, pin connection, key connection, bonding, mortise and tenon connection, welding, riveting and other methods. For example, detachable connection can be selected according to the needs of screw connection, bolt connection, threaded connection, snap connection, mortise and tenon connection, Velcro connection and other methods. The various technical features in the creation of the utility model can be combined interactively without conflicting with each other.

[0031] The embodiment of the utility model provides a nozzle disassembly tool, including a support component, a connecting component 8 and a nozzle extraction component, wherein, with reference to Figure 1 , Figure 3 and Figure 4 The support assembly includes a cavity 1 with an open top, and the cavity 1 can be used to accommodate various additional components and parts. The cavity 1 includes a bottom plate 11 and side plates 12 connected to the edges of the bottom plate 11 to form a rectangular groove-shaped cavity 1 with a simple structure.

[0032] Reference Figure 3 and Figure 4 The connecting assembly 8 comprises an electromagnet 81, a mounting seat 82 and a power supply 83. The power supply 83 is mounted inside the cavity 1, and a switch button of the power supply 83 is arranged outside the side plate 12. The power supply 83, the switch button and the electromagnet 81 are connected in series through a wire, and the power on and off of the electromagnet 81 can be controlled by operating the switch button. A mounting port is arranged on the bottom plate 11 of the cavity 1, and the electromagnet 81 is fixed to the bottom of the cavity 1 (on the bottom plate 11) through the mounting seat 82, and the bottom of the electromagnet 81 extends out of the mounting port, and the bottom of the electromagnet 81 is flush with the bottom of the bottom plate 11. When the tooling is placed in the press of the chemical forming equipment, the lifting frame of the press moves from the bottom of the press to contact with the bottom of the cavity 1, and the electromagnet 81 can directly contact with the lifting frame, so that after the electromagnet 81 is energized, it is adsorbed on the lifting frame, and the connection between the tooling and the lifting frame is realized, and the tooling can move up and down synchronously with the lifting frame.

[0033] Refer to the figure Figure 1-Figure 4The suction nozzle assembly includes a cover plate 2, a probe crimping plate 3 and a clamping claw mechanism. The cover plate 2 is installed on the top of the cavity 1 to cover the opening of the cavity 1. The cover plate 2 is connected to the cavity 1 to form a square box body to prevent the components and parts inside the cavity 1 from being exposed. The probe crimping plate 3 and the clamping claw mechanism are arranged in parallel on the top of the cover plate 2. The probe crimping plate 3 corresponds to the probe module of the formation equipment. When the press is pressed, the probe of the probe module is pressed with the probe crimping plate 3. With the help of the elastic force of the probe spring 562, the electromagnet 81 is more closely adsorbed to the lifting frame, and in the process of pulling out the suction nozzle 9, it provides a reverse force together with the electromagnet 81 to improve the extraction effect of the suction nozzle 9. The clamping claw mechanism includes a clamping claw fixing plate 4 and a plurality of clamping claws 5 arranged at intervals on the clamping claw fixing plate 4. The plurality of clamping claws 5 correspond one-to-one to the plurality of suction nozzles 9 on the negative pressure module, which is convenient for pulling out multiple suction nozzles 9 at the same time and improving work efficiency.

[0034] The front and rear sides of the clamp fixing plate 4 are provided with a beam sensor 6 , which detects whether the suction nozzle 9 is completely removed.

[0035] Reference Figure 1 and Figure 2 In a preferred embodiment, the probe crimping plate 3 and the clamping jaw fixing plate 4 are both slidably connected to the cover plate 2. Specifically, a strip-shaped adjustment hole 22 is provided on the cover plate 2, and the probe crimping plate 3 is provided with a first adjustment rod 31, and a second adjustment rod 41 is provided on the clamping jaw fixing plate 4. The first adjustment rod 31 and the second adjustment rod 41 are both slidably connected in the adjustment hole 22. In this way, the probe crimping plate 3 and the clamping jaw fixing plate 4 can be moved on the cover plate 2, thereby adjusting the position of the probe crimping plate 3 and the clamping jaw mechanism. In order to improve the accuracy of the adjustment position, scale lines are set on the cover plate 2 or on the outside of the side plate 12 so that the two can be accurately aligned with the probe module and the suction nozzle 9.

[0036] In this embodiment, refer to Figure 5-Figure 7The clamping claw 5 includes a fixed seat 51 and two clamping plates 53. The fixed seat 51 is provided with a through hole 52. The two clamping plates 53 are rotatably connected to the fixed seat 51 through a rotating structure 54, and the two clamping plates 53 are symmetrically arranged with the axis of the through hole 52. An elastic member 56 is arranged between the clamping plate 53 and the fixed seat 51. When the clamping plate 53 is rotated downward, the elastic member 56 is in a compressed state. A limiting structure is also arranged between the fixed seat 51 and the clamping plate 53, and the limiting member is used to limit the maximum distance of the clamping plate 53 to rotate upward. The two clamping plates 53 have a clamping surface on the opposite side, and the clamping surface is set to an arc shape according to the shape of the suction nozzle 9. When the clamping plate 53 is rotated upward to the maximum distance, that is, the two clamping plates 53 cannot continue to rotate upward, the two clamping plates 53 are horizontally opposite, and the two clamping surfaces respectively abut against the two sides of the suction nozzle 9, thereby clamping the suction nozzle 9. At this time, the suction nozzle 9 moves upward relative to the clamping plate 53, and the two clamping plates 53 can pull the suction nozzle 9 off the metal rod.

[0037] Specifically, refer to Figure 7 The rotating structure 54 includes a rotating shaft 543 and two lugs 541 arranged parallel to the fixed seat 51. The two lugs 541 are correspondingly provided with first rotating holes 542. The two ends of the rotating shaft 543 are respectively rotatably connected to the two first rotating holes 542. The clamping plate 53 is provided with a second rotating hole 544. The clamping plate 53 is fixedly sleeved on the rotating shaft 543 through the second rotating hole 544, so that the clamping plate 53 rotates relative to the fixed seat 51 based on the rotating shaft 543. In order to increase the downward rotation distance of the clamping plate 53, the fixed seat 51 is provided with an obliquely arranged avoidance groove 55. The avoidance groove 55 is located below the clamping plate 53, and the lower end of the avoidance groove 55 is connected to the through hole 52, so that the clamping plate 53 can rotate up and down in the avoidance groove 55.

[0038] Reference Figure 6 and Figure 7 The elastic member 56 includes a spring 562 and a push rod 563. A mounting hole 561 is provided at the bottom of the avoidance groove 55. The push rod 563 is slidably connected to the mounting hole 561, and the spring 562 is connected between the push rod 563 and the bottom of the mounting hole 561. The end of the push rod 563 away from the spring 562 is set as a hemispherical surface. The push rod 563 is in sliding contact with the bottom of the clamp plate 53 through the hemispherical surface. When the clamp plate 53 rotates downward, the push rod 563 slides into the mounting hole 561, and the spring 562 is compressed. When the external force is eliminated, the restoring force of the spring 562 pushes the push rod 563 to drive the clamp plate 53 to rotate upward.

[0039] Reference Figure 7The limiting structure includes a first limiting surface 57 located on the fixed seat 51 and a second limiting surface 58 located at the bottom of the clamping plate 53. The first limiting surface 57 is connected to the top of the avoidance groove 55. When the first limiting surface 57 abuts against the second limiting surface 58, it is used to limit the clamping plate 53 from continuing to rotate upward.

[0040] In this embodiment, refer to Figure 1 , Figure 3 and Figure 4 A nozzle storage box 7 is provided in the cavity 1, and the nozzle storage box 7 is used to store the pulled-out nozzles 9. The connection method between the nozzle storage box 7 and the cavity 1 can adopt a drawer-type structure, and the nozzle storage box 7 and the cavity 1 can be connected by magnetic attraction, which is convenient for the stability of the nozzle storage box 7.

[0041] In order to improve the collection efficiency of the suction nozzle 9, a feeding hole 42 is provided on the clamping jaw fixing plate 4, and the feeding hole 42 is located directly below the through hole 52 on the fixing seat 51. A drop hole 21 is provided on the cover plate 2. In order to adapt to the adjustment of the clamping jaw mechanism, the drop hole 21 is set as a long opening, and when the clamping jaw fixing plate 4 moves, the drop hole 21 is always located directly below the feeding hole 42. The top of the suction nozzle storage box 7 is set open and located directly below the drop hole 21. In this way, the pulled out suction nozzle 9 passes through the through hole 52, the feeding hole 42 and the drop hole 21 in turn and falls into the suction nozzle storage box 7 below, completing the collection of the suction nozzle 9.

[0042] The use process of the nozzle disassembly tool of the utility model embodiment is as follows:

[0043] After the tooling is placed in the press of the chemical forming equipment, the lifting frame of the press moves from the bottom of the press to contact the bottom plate 11 and the electromagnet 81 at the bottom of the tooling, and the electromagnet 81 is energized. The electromagnet 81 is adsorbed together with the lifting frame, so that the tooling and the lifting frame are connected together, and the two move upward together. When the top of the clamping jaw 5 contacts the suction nozzle 9, the suction nozzle 9 will apply a downward force to the clamping jaw 5. As the upward movement continues, the clamping plate 53 will rotate downward under the influence of the downward force until the suction nozzle 9 enters the through hole 52 and completely disengages from the clamping jaw 5. At this time, the clamping plate 53 returns to the initial state under the action of the spring 562, and the press will stop rising after the pressing is completed. When the pressing action is completed, the press machine starts to disengage from the operation, and the lifting frame drives the tooling to move downward. When it moves to the bottom of the splint 53 and contacts the suction nozzle 9, the suction nozzle 9 will apply an upward force to the splint 53, and the splint 53 cannot rotate upward under the action of the limiting structure. The reaction force of the splint 53 on the suction nozzle 9 pulls the suction nozzle 9 downward, and when the suction nozzle 9 is completely separated from the negative pressure module, it falls into the suction nozzle storage box 7.

[0044] Repeat the above action again, and after pressing again, judge whether there is a problem of missing or incomplete removal of the suction nozzle 9 by the signal feedback of the shooting sensor 6. If so, continue to remove the suction nozzle 9 until it is detected that it is completely removed and stop the action.

[0045] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments.
