Button cell formation and sorting equipment

Abstract

The application discloses a button cell formation and component distribution equipment, which is characterized by being provided with a base, a sliding frame, a sliding device, a jig set and a contact clamp device. When the battery jig is placed in the cabinet, the positioning strips arranged on both sides of the sliding plate can position the battery jig, preventing the battery jig from being deviated during the moving-in process. In addition, the positioning rod and the positioning spring can also position the battery jig, preventing the battery jig from being deviated, so that the contact clamp module can accurately clamp the button cell tab, and the probability of "false clamping" is reduced. Furthermore, the in-place switch arranged on each sliding plate can sense that the battery jig is moved to the predetermined position, and then the subsequent formation and component distribution operation is carried out.

Description

Technical Field

[0001] This invention relates to the field of formation and capacity testing equipment, and in particular to a button cell formation and capacity testing device. Background Technology

[0002] Button batteries, also known as coin cells, are batteries shaped like small buttons. Compared to cylindrical batteries, such as AA batteries, button batteries generally have a larger diameter and are thinner. Button batteries are categorized by their shape; corresponding battery types include cylindrical, square, and irregularly shaped batteries. Button batteries are mainly divided into two categories: one uses a steel casing (hard button batteries), and the other uses an aluminum-plastic film casing (soft button batteries).

[0003] Whether it's a hard-button or soft-button battery, to ensure production quality, the button cells need to undergo formation and capacity testing before production. The purpose of formation and capacity testing is mainly to test various battery parameters to see if they meet production requirements. Current technology generally uses formation and capacity testing equipment to perform this operation. The button cells are fixed in a battery fixture, then the fixture containing the button cells is fed into the equipment. Finally, a tab clamping module holds the tabs of the button cells, thus achieving formation and capacity testing.

[0004] However, existing chemical separation and dispensing cabinets have the following drawbacks:

[0005] First, during the process of feeding the battery fixture into the formation and capacity cabinet, since the formation and capacity cabinet does not have a corresponding positioning structure, the position of the battery fixture may shift slightly during the process of moving in. Once this happens, the tab clamping module will not be able to accurately clamp the tabs of the button battery, resulting in a "virtual clamping".

[0006] Secondly, during the process of feeding the battery fixture into the formation and capacity cabinet, the formation and capacity cabinet cannot determine whether the battery fixture has reached the predetermined position. This requires manual determination of whether the fixture has reached the predetermined position before the formation and capacity of the button cell can be officially started, which will undoubtedly greatly affect the formation and capacity efficiency of the button cell. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a button battery forming and capacity testing device that can prevent the battery fixture from shifting position during the process of moving it into the cabinet, accurately clamp the tabs of the button battery, reduce the probability of "false clamping", and determine whether the battery fixture is in place.

[0008] The objective of this invention is achieved through the following technical solution:

[0009] A button cell battery formation and capacity testing device, comprising:

[0010] Base;

[0011] A carriage, the carriage being disposed on the base;

[0012] A sliding device includes a cylinder assembly, several sliding plates, and several position switches. The cylinder assembly is mounted on the slide frame, and each sliding plate is slidably mounted on the slide frame. The sliding plates are connected sequentially, and the sliding plate furthest from the base is also connected to the drive shaft of the cylinder assembly. Each sliding plate has a positioning rod on both sides, and each sliding plate also has a positioning strip on both sides. Each positioning strip has a positioning spring with a protrusion. Each position switch is correspondingly mounted on a sliding plate.

[0013] The fixture assembly includes a plurality of battery fixtures, each of which is correspondingly mounted on the slide plate; and

[0014] A contact clamp device includes several carrier plates, several clamping modules, and several contact clamping modules. Each carrier plate is disposed on the slide and is located below each slide plate. Each clamping module is disposed on each carrier plate and each contact clamping module is disposed on each clamping module. Each contact clamping module is provided with several clamps. The clamping modules are used to drive the clamps of the contact clamping modules to open or close.

[0015] In one embodiment, a guide portion is provided on the positioning bar at a position away from the positioning switch.

[0016] In one embodiment, the cylinder group includes a first cylinder and a second cylinder, which are respectively disposed on the slide and are axially symmetrical about the central axis of the slide.

[0017] In one embodiment, the clamping module includes a push cylinder, a connecting rod assembly, a first clamping plate, and a second clamping plate. The push cylinder is disposed on the carrier plate, and the connecting rod assembly is slidably disposed on the carrier plate and connected to the drive shaft of the push cylinder. The first clamping plate is slidably disposed on the carrier plate and has a plurality of first clamping slots. The first clamping plate is connected to the connecting rod assembly. The second clamping plate is slidably disposed on the carrier plate and is located above the first clamping plate. The second clamping plate has a plurality of second clamping slots and is connected to the connecting rod assembly. Each first clamping slot corresponds one-to-one with each second clamping slot. Each clamp is disposed one-to-one with each first clamping slot and each second clamping slot. When the push cylinder drives the connecting rod assembly to slide along the carrier plate, the first clamping plate and the second clamping plate slide alternately, thereby causing each clamp of the contact clamping module to open or close.

[0018] In one embodiment, the linkage assembly includes a transverse plate, a first clamping fixing plate, a first connecting rod, a first connecting plate, a second clamping fixing plate, a second connecting rod, and a second connecting plate. The transverse plate is slidably disposed on the carrier plate and is connected to the drive shaft of the push cylinder. The first clamping fixing plate is disposed on the carrier plate. One end of the first connecting rod is rotatably disposed on the first clamping fixing plate, and the other end of the first connecting rod is connected to the transverse plate. The first connecting plate is connected to the first connecting rod and the second clamping plate respectively. The second clamping fixing plate is disposed on the carrier plate. One end of the second connecting rod is rotatably disposed on the second clamping fixing plate, and the other end of the second connecting rod is connected to the transverse plate. The second connecting plate is connected to the second connecting rod and the first clamping plate respectively.

[0019] The advantages and beneficial effects of this invention compared to the prior art are as follows:

[0020] The button battery formation and capacity testing equipment of the present invention, by setting up a base, a slide, a sliding device, a fixture assembly, and a contact clamping device, ensures that when the battery fixture is placed in the cabinet, the positioning strips on both sides of the slide can position the battery fixture and prevent it from shifting during the movement of the battery fixture into the cabinet. In addition, the positioning rods and positioning springs can also position the battery fixture and prevent it from shifting, allowing the contact clamping module to accurately clamp the button battery tabs and reduce the probability of "false clamping". Furthermore, since each slide is equipped with a positioning switch, when the battery fixture moves to the predetermined position, the positioning switch can sense that the battery fixture has moved into place, and then proceed with the subsequent formation and capacity testing operations.

[0033] Please see Figure 1 A button cell battery formation and capacity testing device 10 includes a base 100, a slide 200, a sliding device 300, a fixture assembly 400, and a contact clamp device 500.

[0034] Thus, it should be noted that both the base 100 and the carriage 200 serve a load-bearing function; the sliding device 300 is used to place the fixture assembly 400 and to perform opening and closing operations; the fixture assembly 400 is used to accommodate the button cell battery; and the contact clamp device 500 is used to clamp the tabs of the button cell battery for performing a capacity-forming operation on the button cell battery.

[0035] Please see Figure 1 The carriage 200 is mounted on the base 100.

[0036] Please refer to the following: Figure 1 , Figure 2 and Figure 3 The sliding device 300 includes a cylinder assembly 310, several slide plates 320, and several position switches 330. The cylinder assembly 310 is mounted on the slide frame 200. Each slide plate 320 is slidably mounted on the slide frame 320. The slide plates 320 are connected in sequence. The slide plate 320 away from the base 100 is also connected to the drive shaft of the cylinder assembly 310. Each slide plate 320 is provided with a positioning rod 321 on both sides. Each slide plate 320 is also provided with a positioning strip 322 on both sides. Each positioning strip 322 is provided with a positioning spring 3221. The positioning spring 3221 is provided with a protrusion 3221a. Each position switch 330 is correspondingly mounted on the slide plate 320.

[0037] Please see Figure 1 The fixture assembly 400 includes several battery fixtures 410, each of which is mounted on the skateboard 320 in a corresponding manner.

[0038] Therefore, it should be noted that the battery fixture 410 is used to accommodate button batteries.

[0039] Please refer to the following: Figure 2 and Figure 5The contact clamp device 500 includes several carrier plates 510, several clamping modules 520, and several contact clamping modules 530. Each carrier plate 510 is disposed on the slide 200, and each carrier plate 510 is located below each slide plate 320. Each clamping module 520 is disposed on each carrier plate 510, and each contact clamping module 530 is disposed on each clamping module 520. Each contact clamping module 530 is provided with several clamps 531. The clamping module 520 is used to drive each clamp 531 of the contact clamping module 530 to open or close.

[0040] Therefore, it should be noted that when performing capacity testing on button cells, the button cells are first placed into the battery fixture 410, and then the battery fixture 410 is placed into the slide plate 320. Since the slide plate 320 is equipped with positioning strips 322 on both sides, the positioning strips 322 can position the battery fixture 400 and prevent the battery fixture 400 from shifting position during the movement into the cabinet. In addition, the positioning rods 321 and positioning springs 3221 can also position the battery fixture 400 and prevent the battery fixture 400 from shifting position, so that the contact clamp module 530 can accurately clamp the button cell battery tabs and reduce the probability of "false clamping". Furthermore, since each slide plate 320 is equipped with a position switch 330, when the battery fixture 400 moves to the predetermined position, the position switch 330 can sense that the battery fixture 400 has moved into place, and then the subsequent capacity testing operation can be carried out.

[0041] When the position switch 330 determines that the battery fixture 400 has moved into position, the clamping module 520 drives the clamps 531 of the contact clamping module 530 to open and close. The cylinder group 310 drives each slide 320 to move one by one towards each carrier plate 510. When the slide 320 moves to the predetermined position, each clamp 531 of the contact clamping module 530 will hold the tabs of the button battery located on the battery fixture 410. At this time, the button battery can be formed and tested.

[0042] Furthermore, please refer again. Figure 2 In one embodiment, a guide portion 3222 is provided on the positioning bar 322 at a position away from the position switch 330.

[0043] Therefore, it should be noted that the guide section 3222 makes the process of inserting the battery fixture 400 much simpler.

[0044] Furthermore, please refer again. Figure 2 In one embodiment, the cylinder group 310 includes a first cylinder 311 and a second cylinder 312. The first cylinder 311 and the second cylinder 312 are respectively disposed on the slide 200, and the first cylinder 311 and the second cylinder 312 are axially symmetrical about the central axis of the slide 200.

[0045] Therefore, it should be noted that the cylinder assembly 310 includes a first cylinder 311 and a second cylinder 312, which enables the cylinder assembly 310 to drive the sliding plates 320 to move faster and more smoothly.

[0046] Furthermore, please refer again. Figure 4 In one embodiment, the clamping module 520 includes a push cylinder 521, a connecting rod assembly 522, a first clamping plate 523, and a second clamping plate 524. The push cylinder 521 is mounted on a carrier plate 510. The connecting rod assembly 522 is slidably mounted on the carrier plate 510 and connected to the drive shaft of the push cylinder 521. The first clamping plate 523 is slidably mounted on the carrier plate 510 and has a plurality of first clamping slots. The first clamping plate 523 is connected to the connecting rod assembly 522. The second clamping plate 524 is slidably mounted on the carrier plate 510 and has a second clamping slot. Plate 524 is located above the first opening clamping plate 523. The second opening clamping plate 524 has several second opening clamping slots 524a. The second opening clamping plate 524 is connected to the connecting rod assembly 522. Each first opening clamping slot corresponds to each second opening clamping slot 524a. Each clamp 531 is correspondingly disposed in each first opening clamping slot and each second opening clamping slot 524a. When the push cylinder 521 drives the connecting rod assembly 522 to slide along the carrier plate 510, the first opening clamping plate 523 and the second opening clamping plate 524 slide alternately, thereby causing each clamp 531 of the contact clamping module 530 to open or close.

[0047] Therefore, it should be noted that each clamp 531 is set in the first clamping slot and the second clamping slot 524a in a corresponding manner. When it is necessary to open or close the clamp 531, the cylinder 521 drives the connecting rod assembly 522 to move away from the carrier plate 510, so that the first clamping plate 523 and the second clamping plate 524 slide alternately, that is, the first clamping slot and the second clamping slot 524a are alternately intersected, thus completing the opening and closing operation of the clamp 531.

[0048] Furthermore, please refer again. Figure 4In one embodiment, the linkage assembly 522 includes a transverse plate 5221, a first clamping fixing piece 5222, a first connecting rod 5224, a first connecting piece 5223, a second clamping fixing piece 5225, a second connecting rod 5227, and a second connecting piece 5226. The transverse plate 5221 is slidably disposed on the carrier plate 510 and is connected to the drive shaft of the push cylinder 521. The first clamping fixing piece 5222 is disposed on the carrier plate 510. One end of the first connecting rod 5224 is rotatably disposed on the first clamping fixing piece 5222, and the other end of the first connecting rod 5223 is connected to the transverse plate 5221. The first connecting piece 5223 is connected to the first connecting rod 5224 and the second clamping plate 524, respectively. The second clamping fixing piece 5225 is disposed on the carrier plate 510. One end of the second connecting rod 5227 is rotatably disposed on the second clamping fixing piece 5225. The other end of the second connecting rod 5227 is connected to the transverse plate 5221. The second connecting piece 5226 is connected to the second connecting rod 5227 and the first clamping plate 523 respectively.

[0049] Thus, it should be noted that when the clamping module 520 needs to open or close the clamp 531, the push cylinder 521 drives the transverse plate 5221 to move away from the carrier plate 510. At this time, the first connecting rod 5224 rotates clockwise with the first clamping fixing piece 5222 as the fulcrum, driving the second clamping plate 524 to move closer to the push cylinder 521. The second connecting rod 5227 rotates clockwise with the second clamping fixing piece 5225 as the fulcrum, thereby causing the first clamping plate 523 and the second clamping plate 524 to slide alternately, that is, the first clamping groove and the second clamping groove 524a alternately, completing the opening and closing operation of the clamp 531.

[0050] Furthermore, please refer to the following: Figure 7 and Figure 8 In one embodiment, the battery fixture 410 includes a cartridge 411 and several fixture bodies 412. In one fixture body 412, several positioning posts 412a are provided on one side. A first battery placement hole 412b and several first clearance holes 412c are formed on one side of the fixture body 412, with each first clearance hole 412c distributed around the first battery placement hole 412b. The fixture body 412 also has a... The fixture has a second battery placement hole 412d, a number of second clearance holes 412e, and a number of positioning holes 412f. The second battery placement hole 412d is aligned with the first battery placement hole 412b, and each of the second clearance holes 412e is aligned with each of the first clearance holes 412c. The fixture body 412 has positioning grooves 412g on both sides. The fixture bodies 412 are stacked sequentially and are snapped together with a clip 411 to form a battery fixture 410.

[0051] Therefore, it should be noted that when a button cell battery needs to be placed into the first battery fixture 410, the button cell battery is placed into the first battery placement hole 412b, and the two tabs of the button cell battery will extend into the two first clearance holes 412c. Then, the positioning post 412a of the first battery fixture 410 is aligned with the positioning hole 412f of the second battery fixture 410, and the positioning post 412a of the second battery fixture 410 is aligned with the positioning hole 412f of the third battery fixture 410. This process is repeated. Finally, the fixture bodies 412 are snapped together using the clip 411 to form the battery fixture 410. Then, the battery fixture 410 can be moved into the cabinet. The positioning groove 412g of the battery fixture 410 near the cabinet is aligned with the positioning rod 321 on the slide plate 320, and the battery fixture 410 can be moved into the cabinet.

[0052] Furthermore, please refer to the following: Figure 5 and Figure 6 In one embodiment, the contact clamp module 530 is provided with a plurality of clamps 531. In one clamp 531, the clamp 531 includes a left clamp plate 531a, a right clamp plate 531b, a rotating shaft and a torsion spring 531c. The left clamp plate 531a and the right clamp plate 531b are connected by the rotating shaft. The torsion spring 531c is sleeved on the rotating shaft. One end of the torsion spring 531c is connected to the left clamp plate 531a and the other end of the torsion spring 531c is connected to the right clamp plate 531b.

[0053] Therefore, it should be noted that when the clamp 531 needs to be opened or closed, it is achieved by using the first opening clamp 523 and the second opening clamp 524 that slide alternately. The first opening clamp 523 pushes the left clamp 531a and moves it closer to the right clamp 531b, while the second opening clamp 524 pushes the right clamp 531b and moves it closer to the left clamp 531a, thereby opening the clamp and clamping the button battery tabs.

[0054] The button battery formation and capacity testing equipment of the present invention, by setting up a base, a slide, a sliding device, a fixture assembly, and a contact clamping device, ensures that when the battery fixture is placed in the cabinet, the positioning strips on both sides of the slide can position the battery fixture and prevent it from shifting during the movement of the battery fixture into the cabinet. In addition, the positioning rods and positioning springs can also position the battery fixture and prevent it from shifting, allowing the contact clamping module to accurately clamp the button battery tabs and reduce the probability of "false clamping". Furthermore, since each slide is equipped with a positioning switch, when the battery fixture moves to the predetermined position, the positioning switch can sense that the battery fixture has moved into place, and then proceed with the subsequent formation and capacity testing operations.

[0055] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
