Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of battery manufacturing and assembling, and particularly relates to a device for guiding installation of an end cap of an electrode core. BACKGROUND

[0002] The edge of the electrode foil in the electrode core has an edge, and the welding position generates serious heat during single charging and discharging. The above reasons cause loss of the aluminum plastic film, leading to poor edge resistance, and in severe cases, may cause single liquid leakage. Therefore, the end cap is installed at both ends of the electrode core without a packaging shell to protect the aluminum plastic film.

[0003] The end cap is easy to damage the diaphragm during installation and is not easy to pass through the tab. The existing process uses adhesive tape to fix the diaphragm and the foil first, and then installs the end cap on the single body, so as to protect the diaphragm from being damaged, but the single body manufacturing cost is increased and the production efficiency is reduced. Therefore, it is necessary to provide a safe, reliable and efficient electrode core end cap installation device. CONTENT OF THE UTILITY MODEL

[0004] In view of the deficiencies in the related art, the utility model provides a device for guiding installation of an end cap of an electrode core, which solves the technical problems of difficult installation of the electrode core end cap and easy damage to the single diaphragm in the prior art.

[0005] In one possible implementation, a device for guiding installation of an end cap of an electrode core is provided, which includes an end cap feeding member, an end cap placement table and an end cap. The end cap feeding member includes a string member, a first guide film and a second guide film. The first guide film and the second guide film are fixed to the discharge end of the string member. The electrode core of the super capacitor single body is placed between the first guide film and the second guide film. The end cap placement table is provided with a feeding groove. The end cap is placed in the feeding groove. The feeding end of the string member penetrates the end cap. The feeding end of the string member has a first limiting hole and a second limiting hole. The end cap installation table is provided with a first positioning pin and a second positioning pin corresponding to the feeding end of the string member. The first limiting hole and the second limiting hole are placed on the first positioning pin and the second positioning pin. The end cap penetrates the string member, the first guide film and the second guide film, and is sleeved on the electrode core of the super capacitor single body.

[0006] In one possible implementation, the discharge end of the string member is thinner than the feeding end.

[0007] In one possible implementation, the string member is uniformly thinned from the feeding end to the discharge end.

[0008] In one possible implementation, the discharge end of the string member is 0.1mm to 0.3mm thinner than the feeding end.

[0009] In one possible implementation, a gap fit is adopted between the first limiting hole and the second limiting hole and the first positioning pin and the second positioning pin.

[0010] In a possible implementation, the first guide film and the second guide film are aluminum plastic films, and are fixed to the lower end of the stringed material by heat sealing.

[0011] In a possible implementation, the depth of the feeding groove of the end cap placement table is slightly lower than the height of the end cap.

[0012] Based on the above technical solution, the device for guiding and installing the end cap of the battery cell places the end cap into the feeding groove of the end cap placement table, so that the feeding end of the stringed material penetrates through the end cap, and the end cap is accurately placed in the predetermined position; the feeding end of the stringed material and the end cap placement table are cooperated through the limiting hole and the positioning pin, so that the feeding end of the stringed material is stably fixed; the end cap feeding end includes the first guide film and the second guide film, and the two are fixed to the lower end of the stringed material, and the electrode winding core of the super capacitor monomer is placed between the two guide films, so that the end cap can be accurately guided when being installed on the winding core; the end cap is sleeved into the electrode winding core along the direction of the stringed material; in this way, the damage to the diaphragm and the aluminum plastic film in the installation process is avoided, and the risk of extrusion to the diaphragm and the tab is reduced; the production efficiency is improved, the working time of the personnel is reduced, and the manufacturing cost of the battery / capacitor cell is reduced while the diaphragm is protected.

[0023] To address the technical problems of difficulty in installing electrode core end caps and easy damage to cell diaphragms in existing technologies, this application provides a device for guiding and installing cell end caps.

[0024] See Figure 1 , Figure 2 and Figure 3In one possible implementation, a device for guiding and installing battery cell end caps is provided, including an end cap loading component 110, an end cap placement platform 120, and end caps 200; the end cap loading component 110 includes a stringing component 111, a first guide film 112, and a second guide film 113; the first guide film 112 and the second guide film 113 are fixed to the unloading end of the stringing component 111, and an electrode core of a supercapacitor cell 300 is placed between the two guide films; the end cap placement platform 120 is provided with an inlet groove, in which the end caps 200 are placed; the stringing component 111 is loaded with... The end passes through the end cap 200 and is provided with a first limiting hole 114 and a second limiting hole 115 for installation and fixation; the end cap mounting platform 120 is provided with a first positioning pin 130 and a second positioning pin 140 at the corresponding position of the feeding end of the feeding component 111, and the first limiting hole 114 and the second limiting hole 115 are respectively placed on the first positioning pin 130 and the second positioning pin 140 to ensure the position of the feeding component 111; the end cap 200 is guided by the feeding component 111, the first guide film 112 and the second guide film 113, and is sleeved on the electrode core of the supercapacitor cell 300.

[0025] The device, through the setting of the end cap loading component 110, enables the end cap 200 to be accurately fitted onto the electrode core of the supercapacitor cell 300 along the guiding positions of the string component 111, the first guide film 112, and the second guide film 113; through the cooperation of the first limiting hole 114 and the second limiting hole 115 with the first positioning pin 130 and the second positioning pin 140, the string component 111 is stably fixed, thereby realizing the installation of the end cap 200 and effectively avoiding the influence of the end cap installation on the supercapacitor cell diaphragm.

[0026] In one possible implementation, the unloading end of the feeder 111 is thinner than the loading end, so that the end cap 200 can pass smoothly through the feeder 111 and be fitted onto the electrode core of the supercapacitor cell 300.

[0027] The unloading end of the spool 111 is designed to be thinner than the loading end, in order to reduce the resistance during the fitting process of the end cap, so that the end cap 200 can slide more smoothly to the designated position, effectively improving assembly efficiency.

[0028] In one possible implementation, the feed piece 111 is uniformly thinned from the loading end to the unloading end, so that the end cap can move smoothly onto the electrode core of the supercapacitor cell 300.

[0029] The uniformly thinned design ensures that the material string 111 maintains a smooth transition during the guidance process of the end cap, avoiding blockage or friction caused by sudden changes in thickness, thus enabling the end cap to be installed smoothly.

[0030] The uniformly thinned material string structure design improves the smoothness of the guiding process, reduces jamming, and further optimizes the guiding accuracy of the end cap.

[0031] In one possible implementation, the unloading end of the feeder 111 is 0.1 mm to 0.3 mm thinner than the loading end to further optimize the guiding effect.

[0032] By controlling the thickness difference between the upper and lower ends of the feed assembly to be within the range of 0.1mm to 0.3mm, the best guiding transition effect can be achieved, which helps to reduce assembly friction.

[0033] In one possible implementation, the first limiting hole 114 and the second limiting hole 115 are fitted with the first positioning pin 130 and the second positioning pin 140 with a clearance fit to ensure the flexibility of the end cap guide.

[0034] The clearance fit allows for a small degree of freedom between the limiting hole and the locating pin, ensuring the fine-tuning space of the end cap 200 during assembly and effectively reducing offset problems caused by assembly errors.

[0035] In one possible implementation, the first guide film 112 and the second guide film 113 are made of aluminum-plastic film and are fixed to the unloading end of the material stringing component 111 by heat sealing.

[0036] By fixing the aluminum-plastic film to the unloading end of the material stringer 111 through heat sealing, a stable connection between the guide film and the material stringer 111 can be ensured, effectively preventing it from falling off during use.

[0037] In one possible implementation, the depth of the feed trough of the end cap placement platform 120 is slightly lower than the height of the end cap 200 to ensure the stability of the end cap on the placement platform.

[0038] This utility model provides an auxiliary device for installing battery / capacitor cell end caps, which solves the technical problems of difficulty in installation and easy damage to the cell separator in the prior art. It can quickly and accurately insert the end caps into both ends of the battery / capacitor cell, avoid damage to the battery / capacitor cell separator by the end caps, and reduce the operator's working time and product cost.

[0039] As an example of a device for guiding and installing battery cell end caps, the following description is provided:

[0040] A device 100 for assisting in the installation of battery / capacitor cell end caps is provided. The device 100 includes an end cap feeding component 110, an end cap placement platform 120, and a first positioning pin 130. The end cap feeding component 110 includes a stringing component 111 and a guide plate, namely a first guide film 112 and a second guide film 113. The guide plate / first guide film 112 and second guide film 113 are heat-sealed and fixed to the unloading end of the stringing component 111. The loading end of the stringing component 111 is located inside the feeding groove of the end cap placement platform 120. The first positioning pin 130 is located inside the first limiting hole 114 of the loading end of the stringing component 111 and the second limiting hole 115 of the end cap placement platform 120.

[0041] Preferably, the end cap placement platform 120 has a feeding groove to determine the position of the end cap loading part 110 and to fix it longitudinally.

[0042] Preferably, the end cap placement platform has a feeding trough, the depth of which is slightly lower than the end cap by 200 mm.

[0043] Preferably, the end cap placement platform 120 has a feeding trough, the depth of which is slightly lower than that of the end cap 200.

[0044] Preferably, the limiting holes of the end cap placement platform 120 and the end cap loading component 110 are clearance-fitted with the first positioning pin 130 and the second positioning pin 140, which facilitates the quick replacement of the end cap loading component 110.

[0045] Preferably, the unloading end of the feeding component 111 is 0.1mm to 0.3mm thinner than the loading end, so that when it is connected with the first guide film 112 and the second guide film 113, the overall thickness of the end cap loading component 110 is consistent, which facilitates the loading of the end cap 200 through the end cap loading component 110.

[0046] Preferably, the feeding end of the feeder 111 is chamfered to facilitate the passage of the end cap 200.

[0047] Preferably, the first guide film 112 and the second guide film 113 are aluminum-plastic films, which can be directly fixed to the unloading end of the material stringing component 111 by heat sealing.

[0048] The embodiments described in this application involve setting an end cap feeding component 110, through which an end cap 200 passes and is placed in the feed groove of an end cap placement platform 120. Simultaneously, the first limiting hole 114 of the end cap feeding component 110 is aligned with the second limiting hole 115 of the end cap placement platform 120. A first positioning pin 130 passes through the first limiting hole 114 and the second limiting hole 115 of the end cap feeding component 110 to ensure that the end cap feeding component 110 is fixed on the end cap placement platform 120. A first guide film 112 is provided at the tail of the end cap feeding component 110, and a second guide film 112 is provided at the tail of the end cap feeding component 110. The guide film 113 allows the battery / capacitor cell 300 to be manually placed between the first guide film 112 and the second guide film 113, so that the end cap 200 is inserted into the battery / capacitor cell 300 along the threaded part 111 and the guide piece / first guide film 112 and second guide film 113. Then the first guide film 112 and the second guide film 113 are pulled out. This changes the existing method of applying tape to the separator of the battery / capacitor cell 300, which can reduce the working time of personnel and reduce the manufacturing cost of the cell while protecting the separator of the battery / capacitor cell 300.
