Description

Technical Field

[0001] The invention relates to the field of battery capacity division, and in particular to a button battery capacity division cabinet. Background Art

[0002] Battery formation refers to a series of process measures implemented on the first charged battery to make its performance stable, including low current charging and discharging, constant temperature static, etc. Battery capacity division is to charge and discharge the formed battery, analyze the capacity and internal resistance of these batteries based on the data, and thus determine the quality level of the battery. After the first capacity division of the battery, it needs to be static for a period of time, generally not less than 15 days. During this period, some inherent quality problems will appear, such as excessive self-discharge, increased resistance, etc. After the static period, the capacity division is tested again, and the batteries with capacity that does not meet the grade and quality problems are eliminated.

[0003] The battery capacity division is completed in the capacity division cabinet, and the battery capacity division drawer is an important part of the capacity division cabinet. The capacity division drawer includes a drawer box and contacts. The drawer box can be pulled in and out of the capacity division drawer, and the battery to be divided is placed in the drawer box. For the capacity division of button batteries, since button batteries have various specifications, the two pole ears of some button batteries are at an angle of 90°, and the two pole ears of some button batteries are at an angle of 180°. The traditional capacity division tray is provided with openings on the upper and lower sides of the workstation, through which the positive and negative poles of the button battery are exposed. When the capacity is divided, the positive contact located above the button battery moves downward, and the negative contact located below the button battery moves upward, respectively contacting the button battery, thereby electrically connecting the button battery to the capacity division cabinet. However, the traditional capacity division tray is usually provided with only two openings, so it can only adapt to one specification of button batteries, and is not compatible with button batteries of 90°, 180° or other angles, and this structure is not convenient for repair and replacement when the negative contact located below is damaged.

[0031] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] See also Figures 1 to 3 The present invention provides a button battery capacity distribution cabinet, comprising: a capacity distribution cabinet body 1, a capacity distribution shell 2 arranged on the capacity distribution cabinet body 1, a capacity distribution drawer assembly 3 arranged in the capacity distribution shell 2, and a power supply box arranged at the bottom end of the capacity distribution shell 2, and the capacity distribution drawer assembly 3 is electrically connected to the power supply box.

[0033] See also Figure 4 The divided capacity drawer assembly 3 includes a plurality of divided capacity drawers 4, and the divided capacity drawers 4 include: a lower support assembly 41, a drawer box 42 provided on the lower support assembly 41, an upper support assembly 43 provided above the drawer box 42, and a cylinder 44 provided on the lower support assembly 41 and connected to the upper support assembly 43. The cylinder 44 drives the upper support assembly 43 to move up and down, and the lower support assembly 41 is fixedly mounted on the divided capacity cabinet 1. The batteries to be divided are placed in the drawer box 42, and the drawer box 42 can be pulled in and out on the lower support assembly 41.

[0034] See also Figure 5 and Figure 6 The drawer box 42 includes: a tray bottom plate 421, a male seat 422 disposed on the tray bottom plate 421, and a plurality of capacity-dividing trays 423 disposed on the tray bottom plate 421. The male seat 422 is electrically connected to the power box, and a plurality of workstations 4231 are disposed on the capacity-dividing tray 423, each battery 100 corresponds to a workstation 4231, and the batteries 100 to be divided are placed in the workstations 4231. The lower support assembly 41 is provided with drawer guide rails 45 on both sides corresponding to the drawer box 42, and the drawer box 42 can be drawn in and out on the lower support assembly 41 along the drawer guide rails 45, and the capacity-dividing trays 423 can be removed from the tray bottom plate 421. The drawer box 42 is pulled out from the lower support assembly 41, and the capacity dividing tray 423 is taken down. The staff places the batteries 100 to be divided on the capacity dividing tray 423, and then places the capacity dividing tray 423 on the tray bottom plate 421. After placing, the staff pushes the drawer box 42 onto the lower support assembly 41 to wait for capacity dividing. In this embodiment, two capacity dividing trays 423 are placed on the tray bottom plate 421.

[0035] See also Figure 8The upper supporting assembly 43 includes: a PCB fixing plate 431, a PCB board 432 arranged on the PCB fixing plate 431, a plurality of positive contacts 433 arranged on the PCB board 432, and a plurality of negative contacts 434 arranged on the PCB board 432. Initially, the distance between the upper supporting assembly 43 and the lower supporting assembly 41 is the largest, which is convenient for placing the drawer box 42. When the drawer box 42 filled with batteries is placed, the cylinder 44 drives the upper supporting assembly 43 to descend, and the positive contacts 433 and the negative contacts 434 contact with the tabs of the battery 100 to achieve electrical connection, thereby performing capacity division.

[0036] Since the PCB fixing plate 431 is relatively wide, a reinforcing rib 435 is provided at the front end of the PCB fixing plate 431 to reinforce the PCB fixing plate 431 .

[0037] The compartment housing 2 includes: an outer cover 21, a front baffle 22 provided on the outer cover 21 and corresponding to each compartment drawer 4, a quick clamp 23 provided on the front baffle 22, a start button 24 provided on one side of each compartment drawer 4, and an emergency stop button 25 provided on the other side of each compartment drawer 4. After the drawer box 42 with the battery installed is placed on the lower support assembly 41, the quick clamp 23 fixes the drawer box 42. Both sides of each compartment drawer 4 are provided with a start button 24 and an emergency stop button 25, so that each compartment drawer 4 can be controlled separately. When a compartment drawer 4 has a problem during the compartmentalization process, the compartment drawer 4 can be controlled separately to stop the process without delaying the process of other compartment drawers 4.

[0038] The capacity division tray 423 includes: a first electrode hole 4232 provided beside each of the workstations 4231, a second electrode hole 4233 provided beside each of the workstations 4231, and a third electrode hole 4234 provided beside each of the workstations 4231. A first angle is formed between the first electrode hole 4232 and the second electrode hole 4233, and a second angle is formed between the first electrode hole 4232 and the third electrode hole 4234. The batteries 100 to be divided are placed in the workstations 4231, and one battery 100 is placed in each of the workstations 4231. A positive contact 433 or a negative contact 434 is provided above the first electrode hole 4232, the second electrode hole 4233, and the third electrode hole 4234. The station 4231 is circular, and the main body of the button battery 100 to be divided is placed in the station 4231, and its pole ear is placed toward the first electrode hole 4232, the second electrode hole 4233 or the third electrode hole 4234. The appropriate placement point can be selected according to the angle between the two pole ears of the button battery. Therefore, the present invention is applicable to button batteries of two specifications. In this embodiment, the first angle is 90° and the second angle is 180°, which is applicable to button batteries of two common specifications with the two pole ears having an angle of 90° or 180°. Of course, the first angle and the second angle can also be set to any other angle.

[0039] The positive contact 433 and the negative contact 434 are both disposed above the drawer box 42. A positive contact 433 or a negative contact 434 is correspondingly disposed above the first electrode hole 4232, the second electrode hole 4233, and the third electrode hole 4234. The positive contact 433 or the negative contact 434 can be shared. For example, when the positive contact 433 is shared, the positive contact 433 is disposed above the first electrode hole 4232, and the negative contact 434 is disposed above the second electrode hole 4233 and the third electrode hole 4234. When placing the button battery 100, one pole ear needs to be placed corresponding to the first electrode hole 4232, and the other pole ear needs to be placed in a suitable second electrode hole 4233 or third electrode hole 4234, so that the number of contacts can be saved. Two guide protrusions 4235 are provided on one side of the first electrode hole 4232, the second electrode hole 4233 and the third electrode hole 4234 close to the work station 4231, and the battery ear is located between the two guide protrusions 4235, which limit the button battery 100 to prevent the button battery 100 from rotating and shifting, thereby affecting the capacity division effect.

[0040] The tops of the first electrode hole 4232, the second electrode hole 4233 and the third electrode hole 4234 are countersunk holes, and the contact gasket 200 is embedded in the countersunk holes. The capacity division tray 423 is made of plastic material, and the contact gasket 200 is made of metal. Since the upper contact will be pressed down to contact the pole ear during capacity division, if it is a plastic material, it will be easily worn and damaged. Therefore, the present invention is provided with a metal contact gasket 200. The contact will exert force on the metal contact gasket 200 when it is pressed down. The metal has good wear resistance, which increases the service life of the capacity division tray 423. In addition, the metal has the function of conducting electricity, and can conduct electricity away when there is an abnormality in the capacity division process.

[0041] See also Figure 7 The lower support assembly 41 includes a drawer support plate 411 and guide shafts 412 arranged at the four corners of the drawer support plate 411. The PCB fixing plate 431 is provided with through holes corresponding to the guide shafts 412. The guide shafts 412 pass through the through holes. Two of the through holes are provided with bearings 300. The two guide shafts 412 pass through the bearings 300 respectively. The other two guide shafts 412 are sleeved with springs 400, and washers 500 are provided at the tops thereof to limit the springs 400. The cylinder 44 drives the upper support assembly 43 to move up and down along the guide shafts 412. The springs 400 play a buffering role when the upper support assembly 43 moves up and down.

[0042] The two sides of the sub-capacity tray 423 are provided with bumps 4236. Since the sub-capacity tray 423 is relatively large, the multiple downward pressures of the upper support assembly 43 may cause the sub-capacity tray 423 to deform, so the bumps 4236 are provided, and the downward pressure acts on the bumps 4236, so that the sub-capacity tray 423 is deformed.

[0043] The drawer support plate 411 is provided with a bar hole 4111, and the bottom surface of the tray bottom plate 421 is provided with a boss corresponding to the bar hole 4111, and the bottom end of the boss is provided with an external thread, and the boss passes through the bar hole 4111 and a nut is sleeved on the bottom end of the boss. The drawer box 42 is pulled in and out along the bar hole 4111. Due to the boss, when the drawer box 42 moves to the limit position, it will be stuck in the bar hole 4111, so the drawer box 42 cannot be completely pulled out from the lower support assembly 41, preventing the drawer box 42 from hitting the feet of the staff when it is completely pulled out.

[0044] The tray bottom plate 421 is provided with an indicator light corresponding to each station 4231, and the capacity division tray 423 is provided with a light transmission hole 4237 corresponding to the indicator light, and the indicator light is located in the light transmission hole 4237. When the battery 100 in the station 423 has capacity division abnormality, the corresponding indicator light will light up to give a prompt.

[0045] In summary, the present invention has the following beneficial effects:

[0046] 1. The present invention arranges both the positive contact and the negative contact above the battery. When the contact is damaged, since both are located above, it is convenient to repair and replace, and this structure saves more space.

[0047] 2. The battery capacity distribution tray of the present invention is provided with a first electrode hole, a second electrode hole and a third electrode hole on the side of the work station, a first angle is formed between the first electrode hole and the second electrode hole, and a second angle is formed between the first electrode hole and the third electrode hole, so it can be suitable for button batteries of two specifications, thereby improving the compatibility of the product.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
