Description

Technical Field

[0001] The present disclosure relates to the technical field of battery restraint, and in particular to a restraint device for quickly replacing batteries. Background Art

[0002] During the manufacturing process of batteries, batteries need to go through a series of complex processes and workstations to ensure their quality and performance. In order to ensure the stability and consistency of the battery during the production process, a battery restraint device is needed to fix the battery. The battery restraint device is a device used in the battery production and manufacturing process, which is mainly used to fix the battery to ensure the stability of battery production and product quality. However, the existing battery restraint device has some limitations and cannot adapt to square batteries of various specifications and sizes. This leads to the inability to achieve quick replacement and one-click restraint during the production process, which increases the complexity and time cost of the operation; in addition, the current battery restraint device is prone to battery bulging problems during the formation process, and the inability to effectively restrain the battery will lead to inefficiency and increased costs. Therefore, a new type of battery restraint device is needed to solve these problems, improve production efficiency and reduce costs.

[0003] After searching, it is known that in the prior art, for example, patent CN202221955992.X discloses a battery restraint tray and formation device suitable for square battery formation. The battery restraint tray includes a bottom plate, a side plate, a battery clamping assembly and a locking drive. A telescopic structure is provided between the battery clamping assembly and the locking drive. The battery clamping assembly is provided with a plurality of clamps for clamping the battery. The side plates are provided on both sides of the bottom plate. Parallel guide rods are provided between the side plates. The battery clamping assembly is slidably connected to the guide rods and connected to the telescopic structure. The locking drive is installed on the bottom plate. A pressure gauge interface is provided at one end of the locking drive for connecting a pressure gauge to detect pressure. The locking drive drives the telescopic structure, and then drives the battery clamp to clamp the battery. The above-mentioned battery restraint tray and formation device suitable for square battery formation still have the following defects in actual applications:

[0004] First, when the clamp is clamped on the battery, it is necessary to observe the pressure value of the pressure gauge connected to the cylinder to determine whether the battery is tightly clamped. Once the battery is tightly clamped, the battery shape is restrained. This method of clamping the battery relies on the cylinder pressure and the pressure gauge reading to determine whether the battery is tightly clamped. There is a certain degree of uncertainty. If the pressure gauge fails or the reading is inaccurate, the battery may not be clamped correctly or damaged; and this clamping method cannot achieve one-click restraint and compression.

[0005] Secondly, this clamping method can only be applied to batteries of a single specification and may not be applicable to batteries of other specifications. If batteries of different specifications need to be produced on the production line at the same time, different restraint devices may need to be used, which increases the complexity of equipment and production.

[0039] like Figure 1 - Figure 7 As shown, a fast battery replacement restraint device disclosed in the present disclosure includes a battery tray 10, a drive assembly 20, a battery restraint assembly 30 and an elastic guide assembly 50;

[0040] The driving assembly 20 is disposed at one end of the battery tray 10 , and a first fixed mold base 308 is disposed at the other end of the battery tray 10 ;

[0041] The elastic guide assembly 50 includes a guide shaft 501 and an elastic member 502, and the guide shaft 501 extends from the driving assembly 20 to the first fixed mold base 308;

[0042] The battery restraint assembly 30 includes at least two groups of movable mold seats arranged along the axial direction of the guide shaft. The movable mold seats are slidably arranged on the battery tray 10 and cooperate with the guide shaft 501 so that the movable mold seats can slide along the axial direction of the guide shaft 501. The batteries 40 are placed between two adjacent groups of movable mold seats, and an elastic member 502 is provided between each two adjacent groups of movable mold seats. The elastic member 502 is configured to make the two adjacent groups of movable mold seats have a tendency to move away from each other. The elastic member 502 can be a compression spring.

[0043] The driving assembly 20 is linked with the movable mold base to drive the movable mold base to slide along the axial direction of the guide shaft 501 to cooperate with the first fixed mold base 308 to clamp the battery 40; that is, the movable mold base moves toward one end of the first fixed mold base 308, so that the battery 40 placed between the two sets of movable mold bases is clamped;

[0044] The elasticity of the elastic member 502 makes the adjacent movable mold seats have a tendency to move away from each other, and the battery 40 can be released after the driving assembly 20 stops the linkage with the movable mold seat;

[0045] The driving component 20 is linked with the movable mold base, so that the movable mold base slides axially along the guide shaft 501, thereby clamping the battery 40, realizing one-click restraint clamping, and the movable mold base moves along the guide shaft 501 to perform a clamping action. The elastic force of the elastic member 502 can prevent the movable mold base from clamping the battery 40 too tightly; when it is necessary to release the battery 40, the driving component is stopped, and the elastic force of the elastic member 502 can make the movable mold base rebound to the initial position, thereby quickly releasing the battery 40 to quickly remove or place the battery 40.

[0046] Furthermore, in this embodiment, the movable mold base includes a base body and a partition embedded in the base body, the base body is slidably connected to the battery tray 10, and the partition is used to abut against the battery 40; if multiple batteries 40 are restrained, multiple groups of base bodies need to be set, and according to the different positions of the multiple groups of base bodies, the base bodies and the corresponding partitions are divided into the following:

[0047] The mold base includes a first base body 301, a second base body 302 and a third base body 303. The first base body 301 is disposed at one end of the battery restraint assembly 30 close to the driving assembly 20, the third base body 303 is disposed at one end away from the driving assembly 20, and the second base body 302 is disposed between the first base body 301 and the third base body 303;

[0048] The partition includes a first partition 304, a second partition 305 and a third partition 306. The first partition 304 and the second partition 305 are both provided on the first seat body 301 and the third seat body 303. The first partition 304 and the second partition 305 are sequentially arranged in a direction close to the second seat body 302. The third partition 306 is arranged on the second seat body 302.

[0049] If two sets of movable mold bases are selected, only the first base body 301 and the third base body 303 are required, and the battery 40 is placed between the first base body 301 and the third base body 303 and clamped; if multiple sets of movable mold bases are selected, a corresponding number of second base bodies 302 are arranged at intervals between the first base body 301 and the third base body 303, so that the battery 40 can be placed between the first base body 301 and the second base body 302, between two adjacent second base bodies 302, and between the second base body 302 and the third base body 303; and when the partition is clamped, the battery 40 is in large contact with the surface of the battery 40, thereby eliminating bulging of the battery 40 during the formation process.

[0050] Furthermore, in this embodiment, the seat body has a plurality of embedding grooves adapted to the partitions, and the plurality of embedding grooves are distributed in a stepped manner along the axial direction of the guide shaft 501, so that the plurality of embedding grooves can be adapted to partitions of various widths respectively;

[0051] Specifically, the first base body 301 and the third base body 303 are both "L"-shaped structures, and the embedding groove is provided on one side, and the corresponding embedding groove is the first embedding groove, and the bottom of the first partition plate 304 and the bottom of the second partition plate 305 are both embedded in the first embedding groove;

[0052] The second seat body 402 is an "L"-shaped structure, and the embedding groove is provided in the middle area, and the corresponding embedding groove is a second embedding groove, and the structure of the second embedding groove is a plurality of steps recessed from both sides to the middle, and the bottom of the third partition plate 306 is embedded in the second embedding groove;

[0053] The openings of the "L"-shaped structures of the first base body 301, the second base body 302 and the third base body 303 are oriented in the same direction, and the opening of the first mounting groove is oriented toward a side away from the second base body 302;

[0054] Each two separators are used to clamp the two sides of the battery 40, that is, the second separator 305 and the third separator 306 are used to clamp the battery 40 from both sides, and the two third separators 306 are used to clamp the battery 40 from both sides, so that the separators are in contact with the surface of the battery 40 over a large area, which can eliminate the bulging of the battery 40 during the formation process;

[0055] According to the above structure, the multiple embedded grooves distributed in a ladder shape can be used to place partitions of different specifications. The corresponding partitions are selected according to the specifications of the battery 40 used, and then embedded in the corresponding embedded grooves. According to the size specifications of the battery 40, the appropriate thickness of the partition is selected, so that the battery 40 of the appropriate specification can be placed. Therefore, the above structure enables the fast-changing battery restraint device to restrain batteries 40 of different specifications.

[0056] Furthermore, in this embodiment, the battery restraint assembly 30 further includes a force plate 307, which is disposed at one end of the battery restraint assembly 30 close to the drive assembly 20, and is used to cooperate with the drive assembly 20 to push the movable mold base to slide;

[0057] In summary, the battery restraint assembly 30 is composed of a force plate 307, a first partition 304, a second partition 305, a first base 301, a plurality of second bases 302 arranged at intervals, a plurality of third partitions 306 arranged on the second base 302, a second partition 305, a first partition 304 and a first fixed mold base 308, which are arranged in sequence from one end close to the driving assembly 20.

[0058] In addition, the guide shaft 501 selects an optical axis, and the number is preferably three, which are distributed along the "L"-shaped structural paths of the first base body 301, the second base body 302 and the third base body 303 respectively. The three guide shafts 501 are distributed in a triangle-like positioning so that the movable mold base can slide in a directional manner from one end close to the driving assembly 20 to the first fixed mold base 308 to clamp the battery 40.

[0059] Furthermore, in this embodiment, the driving assembly 20 includes a telescopic mechanism 201, a cylinder 202, and a second fixed mold base 203;

[0060] The second fixed mold base 203 is disposed at one end of the battery tray 10, the telescopic mechanism 201 is disposed on a side of the second fixed mold base 203 close to the battery restraint assembly 30, and the cylinder 202 is disposed on a side of the second fixed mold base 203 away from the battery restraint assembly 30;

[0061] The output end of the cylinder 202 is connected to one end of the telescopic mechanism 201 to provide power for the telescopic mechanism 201 to move. The action of the cylinder 202 pushes the telescopic mechanism 201 to move toward the movable mold base, so as to push the movable mold base to clamp the battery 40 .

[0062] Further, in this embodiment, the telescopic mechanism 301 includes a telescopic rod and a pressing block;

[0063] One end of the telescopic rod is connected to the output end of the cylinder 202, and the other end is connected to the pressure block, so that the pressure block is driven by the telescopic rod to perform an extrusion movement toward the force-bearing plate 307 or a contraction movement away from the force-bearing plate 307. The extrusion movement clamps the battery 40, and the contraction movement retracts the telescopic rod, and the movable mold base is rebounded to the initial position through the elastic member 502 to release the battery 40 or expand the adjacent second partition 305 to open a certain space to place the battery 40.

[0064] Furthermore, in this embodiment, a tray pad 60 is provided on the battery tray 10, and the tray pad 60 is located between the battery tray 10 and the battery restraint assembly 30, and the tray pad 60 is made of corrosion-resistant material. A stainless steel tray pad 60 is arranged on the battery tray 10, so that when the device performs restraint movement, it can reduce the friction generated by the restraint movement and prevent corrosion of the battery tray 10.

[0065] The following will combine the above content to fully explain the working process of a restraint device for quickly replacing batteries in this embodiment.

[0066] In the initial state of the restraint device for rapid battery replacement, the battery 40 can be placed between the first seat 301 and the second seat 302, between two adjacent second seats 302, and between the second seat 302 and the third seat 303. The cylinder 202 is started, and the output end of the cylinder 202 drives the telescopic mechanism 201 to move toward the battery restraint assembly 30. The telescopic mechanism 201 pushes the pressure block, which in turn causes the pressure block to push the force plate 307. The force plate 307 pushes the first partition plate 304, the second partition plate 305, the first seat 301, and a plurality of second seats 302 arranged at intervals to move. The positioning is distributed in a triangle-like manner through three guide shafts 501. The battery restraint assembly 30 can move in a directional manner from one end close to the driving assembly 20 to the other end to clamp the battery 40. The elastic force of the elastic member 502 sleeved on the outer surface of the guide shaft 501 can prevent the movable mold base from clamping the battery 40 too tightly. When the battery 40 needs to be released, the driving assembly 20 is stopped. The elastic member 502 is provided between the first seat body 301 and the second seat body 302, between two adjacent second seat bodies 302, and between the second seat body 302 and the third seat body 303. The elastic force of the elastic member 502 can make the movable mold base rebound to the initial position, thereby quickly releasing the battery 40 so as to quickly remove or place the battery 40.

[0067] The above method realizes the rapid clamping and releasing of the battery 40 , and enables the rapid replacement and clamping of the battery 40 .
