Description

Technical Field

[0001] This utility model relates to the field of battery production equipment technology, and in particular to a battery cell module clamping device. Background Technology

[0002] In the production process of power battery cell modules, the handling of these modules needs to meet the requirements of high precision and high stability. Existing clamping devices mainly suffer from the following drawbacks: First, the lack of mechanical interlocking makes the modules prone to falling during sudden power outages or abnormal air pressure, causing damage to expensive battery cell modules. While existing technologies include clamping devices with limit pins, their limiting mechanisms are fixed to the support base and cannot move synchronously with the clamping unit, failing to meet the variable-pitch clamping requirements of different battery cell module specifications. Second, the guide and drive components are directly mounted on the support substrate, requiring complete disassembly for replacement, making maintenance difficult. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a battery cell module clamping device.

[0004] The technical solution of this utility model is: including a carrier substrate; including: Two sets of clamping units are symmetrically mounted on the carrier substrate. Each set of clamping units includes a clamping drive assembly, a drive connection plate connected to the drive output end of the clamping drive assembly, and a clamping arm connected to the drive connection plate. The clamping arm opens and closes symmetrically under the drive of the clamping drive assembly to clamp the battery cell module. The locking unit, which forms a linkage anti-fall system with the clamping unit, is disposed on the drive connecting plate and moves along the clamping direction with the drive connecting plate.

[0005] A further technical solution is as follows: the locking unit includes: a follower base plate that is vertically fixedly connected to the drive connection plate, a vertical drive component fixed on the follower base plate, and a limiting pin driven by the vertical drive component, wherein the limiting pin cooperates with the limiting pin hole on the battery cell module.

[0006] A further technical solution is that the locking unit further includes a second guide component, the second guide component includes a second linear slide rail extending in a vertical direction, and the limiting pin is slidably connected to the second linear slide rail via a sliding seat.

[0007] A further technical solution is that a coaxial mounting through hole is provided at the corresponding position of the bearing substrate, and the coaxial mounting through hole forms a motion channel for the locking unit to move along the clamping direction with the driving connecting plate.

[0008] A further technical solution is as follows: a first guide component is provided between the carrier substrate and the drive connection plate. The first guide component includes a first linear slide rail extending along the clamping motion direction. The drive connection plate is slidably connected to the first linear slide rail under the drive of the clamping drive component.

[0009] A further technical solution is that each side of the drive connection plate corresponds to two sets of symmetrically arranged first linear slide rails.

[0010] A further technical solution includes a detachable mounting plate, which is fixed to the lower end face of the supporting substrate by locking bolts, and the first linear slide rail and clamping drive assembly are fixedly mounted on the mounting plate.

[0011] A further technical solution is that the inner side of the clamping part of the clamping arm is provided with a strip-shaped protrusion, which cooperates with the strip-shaped groove on the side of the battery cell module.

[0012] A further technical solution is that the clamping arm is provided with a U-shaped clearance notch in the middle, which divides the clamping arm into two symmetrical clamping parts.

[0013] A further technical solution is that the clamping drive assembly is a dual-stroke drive component, which drives two sets of drive connecting plates to move synchronously through a synchronization mechanism to achieve symmetrical opening and closing of the clamping arms on both sides.

[0014] The beneficial technical effects of this utility model are: by rigidly connecting the locking unit and the clamping unit, the limiting pin can move synchronously with the clamping arm along the clamping direction. When the limiting pin is fully inserted into the limiting pin hole of the battery cell module, a reliable mechanical interlock is formed, which effectively prevents the clamping arm from opening accidentally due to sudden power failure, abnormal air pressure or other faults, and completely eliminates the risk of the battery cell module falling.

Detailed Implementation

[0016] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0017] like Figure 1 and Figure 2 As shown, the battery cell module clamping device of this utility model includes a support base plate 1, which is used to connect to a robot or a fixed frame. Two sets of clamping units 2 are symmetrically mounted on the support base plate 1. Each clamping unit 2 includes a clamping drive assembly 21 for providing clamping power, a drive connecting plate 22, and a clamping arm 23. The clamping arm 23 is vertically fixedly connected to the drive connecting plate 22 and is used to directly clamp the side wall of the battery cell module 100. A first guide assembly 24 is provided between the support base plate 1 and the drive connecting plate 22. The first guide assembly 24 includes a first linear slide rail extending along the clamping movement direction. The drive connecting plate 22 is connected to the drive output end of the clamping drive assembly 21 and is slidably connected to the first linear slide rail under the drive of the clamping drive assembly 21.

[0018] In this embodiment, four sets of first linear slide rails are provided below the bearing substrate 1, and the drive connection plate 22 on each side corresponds to two sets of symmetrically arranged first linear slide rails, so as to significantly improve the stability of the clamping movement and the resistance to off-center load.

[0019] Furthermore, a detachable mounting plate 25 is provided on the lower end face of the support substrate 1. The mounting plate 25 is fixedly connected to the support substrate 1 by locking bolts, and the first linear slide rail and the clamping drive assembly 21 are fixedly mounted on the mounting plate 25. The detachable design of the mounting plate 25 not only ensures the installation accuracy of the first linear slide rail, but also facilitates the replacement of the mounting plate individually during subsequent maintenance, avoiding repeated processing of the support substrate 1.

[0020] In another embodiment, the clamping drive assembly 21 is a dual-stroke drive component, preferably a dual-acting cylinder or a dual-output servo cylinder, and drives two sets of drive connecting plates 22 to move synchronously through a synchronization mechanism to achieve symmetrical opening and closing of the clamping arms 23 on both sides.

[0021] In this embodiment, the clamping drive assembly 21 adopts a clamping cylinder, and the connection between the drive connecting plate 22 and the clamping arm 23 is provided with an L-shaped right-angle reinforcing structure. The L-shaped right-angle reinforcing structure is used to enhance the rigidity of the clamping arm 23, prevent deformation during clamping, and improve the reliability of long-term use.

[0022] Furthermore, the clamping arm 23 is provided with a U-shaped clearance notch 3 in the middle, which divides the clamping arm 23 into two symmetrical clamping parts. Each clamping part has a strip-shaped protrusion 26 on its inner side. The cross-section of the strip-shaped protrusion 26 is trapezoidal and cooperates with the strip-shaped groove 102 on the side of the battery cell module 100 to achieve rapid and accurate positioning and enhance the reliability of clamping.

[0023] The clearance notch 3 can serve as a detection window. For example, a laser rangefinder or a visual positioning camera can monitor the positioning status of the battery cell module 100 in real time through the clearance notch 3. Alternatively, the clearance notch 3 can serve as an anti-interference design. When a high-voltage terminal is arranged on the side of the battery cell module 100, the clearance notch 3 can form a clearance to the high-voltage terminal.

[0024] It also includes two sets of locking units 4, each corresponding to one of the clamping units 2 on each side, such as... Figure 3 The locking unit 4 and the clamping unit 2 constitute a linkage anti-fall system. The locking unit 4 is vertically fixed to the drive connecting plate 22 through the follower base plate 41 and moves synchronously along the first linear slide rail with the drive connecting plate 22. The bearing base plate 1 and the mounting plate 25 are provided with coaxial mounting through holes 5 at corresponding positions. The coaxial mounting through holes 5 form the movement channel of the locking unit 4.

[0025] Specifically, such as Figure 4 and Figure 5 The locking unit 4 includes a vertical drive member 42, a second guide component 43, and a locking execution component fixed on the follower substrate 41. The second guide component 43 includes a second linear slide rail extending in the vertical direction. The locking execution component includes a sliding seat 44 driven by the vertical drive member 42 and a limiting pin 45. The sliding seat 44 is slidably connected to the second linear slide rail under the drive of the vertical drive member 42. The limiting pin 45 is transitionally engaged with the limiting pin hole 101 on the cell module 100.

[0026] In this embodiment, the vertical drive component 42 is a locking cylinder, and the piston rod of the locking cylinder is arranged downwards. Two sets of limiting pins 45 are fixed to the sliding seat 44 through connecting seats to form a balanced locking of the battery cell module 100.

[0027] When the battery cell module 100 needs to be clamped, the clamping cylinder drives the clamping arm 23 to close, and the locking cylinder pushes down the limit pin 45 and inserts it into the limit pin hole 101 to form a mechanical interlock to prevent the clamping arm 23 from being opened accidentally. When the battery cell module 100 needs to be released, the locking cylinder drives the piston rod to retract, the limit pin 45 exits the limit pin hole 101, and the clamping cylinder drives and opens the clamping arm 23.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
