Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, and in particular to a variable-size patch device. Background Technology

[0002] Cell mounting fixtures play a crucial role in battery production. However, traditional cell mounting fixtures have many limitations. Their structural design and limited cell conversion methods severely restrict the improvement of battery production efficiency, hinder the process of production line transformation, and lead to increased costs.

[0003] On the one hand, existing cell mounting fixtures can only meet the top mounting requirements of cells of specific sizes. When faced with production tasks involving cells of different sizes, they cannot be adapted, greatly extending the cell top mounting changeover time and reducing production efficiency. This results in the production line being idle when changing cell models, increasing the difficulty and risk of production line modification and prolonging the debugging cycle.

[0004] On the other hand, during the cell patching and replacement process, the cell assembly position is prone to loosening, making it difficult to fully guarantee the safety of the cell patching process and posing potential production hazards.

[0005] In summary, there is an urgent need for a simple and efficient battery cell mounting fixture that can adapt to the mounting requirements of various battery cell sizes to improve the safety of battery cell top mounting. Utility Model Content

[0006] The main purpose of this invention is to provide a variable-size chip mounting device, which aims to optimize the structure of the chip mounting fixture, improve the safety of chip mounting, and is applicable to chips of different sizes.

[0007] To achieve the above objectives, this utility model proposes a variable-size patch device, comprising: The base plate has through holes; One or two pairs of adjusting blocks are slidably connected to one side wall of the base plate in the first direction; Two diagonal plates, each pair of said diagonal plates being slidably connected to the adjusting block in a second direction, and being able to move closer to or further away from each other; Wherein, the first direction and the second direction are perpendicular, and the two pairs of corner plates are located around the through hole, so as to abut against the corner of the battery cell respectively.

[0008] In the above scheme, the base plate has a square structure. The first direction can be the width direction of the base plate, and the second direction can be the length direction of the base plate. This allows the adjusting block to be adjusted in the width direction of the base plate, and the corner plate to be adjusted in the length direction of the base plate. When the battery cell is placed on the base plate, the corner plate is gradually and tightly fitted to the four corners of the battery cell by adjusting the adjusting block and the corner plate, ensuring that the position of the battery cell is fixed and preventing the problem of shaking during the mounting process.

[0009] Furthermore, the system includes a first bracket, a lifting assembly, and a top plate positioned below the through hole. The lifting assembly is mounted on the first bracket, and the top plate is connected to the output shaft of the lifting assembly and located directly below the through hole. The lifting assembly drives the top plate to move upward and through the through hole. The lifting assembly moves the top plate to the through hole until it pushes the battery cell above the through hole out, achieving chip mounting. Simultaneously, the corner plate continuously restricts the corners of the battery cell, ensuring that the cell does not wobble.

[0010] Furthermore, the lifting assembly includes a linear actuator, a guide column, and a lifting plate. The linear actuator is mounted on the first bracket, and the guide column is slidably disposed on the linear actuator. The top plate is mounted on the end of the guide column facing the through hole, and the output shaft of the linear actuator is connected to the lifting plate. The guide column and the lifting plate are used to connect the linear actuator and the top plate. When the linear actuator is activated, it drives the lifting plate to rise until the lifting plate, through the guide column, lifts the top plate upwards until the top plate extends out of the through hole, thus lifting the battery cell upwards to attach the chip.

[0011] Furthermore, the top plate and the through hole have the same shape, both being cross-shaped. This improves the uniformity of force applied to the ejected battery cell. In addition, elliptical or parallelogram shapes can also be used. This approach considers the versatility of the product and ensures that battery cells of different sizes can be subjected to uniform force. Preferably, the top plate and through hole are cross-shaped.

[0012] Furthermore, the device includes a rotating plate, with base plates mounted on its edges. A rotary actuator is located in the center of the rotating plate, driving the base plates to move sequentially above the top plate. The through-hole penetrates the rotating plate. The rotating plate can be circular, with the base plates arranged sequentially along its edges. Preferably, the rotating plate is square, with the base plates distributed at both ends. When the rotary actuator rotates to adjust the rotating plate, it drives the base plates to perform a reversal operation, enabling subsequent cell mounting operations and improving switching efficiency.

[0013] Furthermore, the rotary actuator is located below the rotating plate, and its output end is fixedly connected to the rotating plate. A second bracket is provided at the rotary actuator, and the rotary actuator is mounted on the top of the second bracket.

[0014] Furthermore, the base plate is provided with sliding grooves at both ends in the first direction, and the adjusting block is slidably mounted on the base plate through the sliding grooves.

[0015] Furthermore, the groove is lower than the upper surface of the base plate.

[0016] Furthermore, a slide is provided on the side of the adjusting block facing the corner plate, and the corner plate is slidably connected to the adjusting block through the slide.

[0017] Furthermore, the corner plate has an L-shaped cross-section.

[0018] The above technical solution has the following advantages: This application sets an adjustment block that moves in a first direction on the base plate, and sets corner plates that move in a second direction on the adjustment block. By having the two corner plates abut against the four corners of the battery cell, it can better fit the surface of the battery cell and adapt to different battery cell sizes, so as to prevent the battery cell from shaking during the patching process, which would affect the stability and safety of the patching.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain this utility model and do not constitute a limitation on this utility model.

[0022] like Figure 1 and Figure 3 As shown, a variable-size patch device includes a base plate 5, one or two pairs of adjusting blocks 8, and two diagonal plates 7. The base plate 5 has a through hole 51. One or two pairs of adjusting blocks 8 are slidably connected to one side wall of the base plate 5 in a first direction. Each diagonal plate 7 is slidably connected to the adjusting block 8 in a second direction and can move closer or further away from each other. The first direction and the second direction are perpendicular, and the two diagonal plates 7 are located around the through hole 51 to abut against the corner of the battery cell.

[0023] The base plate 5 has a square structure. The first direction can be the width direction of the base plate 5, and the second direction can be the length direction of the base plate 5. This allows the adjusting block 8 to be adjusted in the width direction of the base plate 5, and the corner plate 7 to be adjusted in the length direction of the base plate 5. When the battery cell is placed on top of the base plate 5, the adjusting block 8 and the corner plate 7 are adjusted so that the corner plate 7 gradually fits tightly against the four corners of the battery cell, ensuring that the position of the battery cell is fixed and preventing the problem of shaking during the mounting process.

[0024] Specifically, one or two pairs of adjustment blocks 8 can be selected. If one pair of adjustment blocks 8 is selected, the two adjustment blocks 8 are slidably connected in the first direction of the base plate 5. The two corner plates 7 in the length direction of the base plate 5 are respectively installed at both ends of the adjustment blocks 8. By adjusting the position of the two adjustment blocks 8, the two corner plates 7 can be driven to select the width of the battery cell. If two pairs of adjustment blocks 8 are selected, there are four adjustment blocks 8 and four corner plates 7, all located around the base plate 5. In this case, the two corner plates 7 in the length direction of the base plate 5 need to be installed on the adjustment blocks 8 on the corresponding side. That is, when one pair of adjustment blocks 8 is selected, the two corner plates 7 are installed at both ends of the same adjustment block 8. When two pairs of adjustment blocks 8 are selected, each corner plate 7 is connected to the corresponding adjustment block 8. Only the corresponding adjustment block 8 needs to be adjusted to adapt to battery cells of different widths.

[0025] like Figure 1 and Figure 2 As shown, this application includes a first bracket 1, a lifting assembly 6, and a top plate 4 positioned below the through hole 51. The lifting assembly 6 is mounted on the first bracket 1, and the top plate 4 is connected to the output shaft of the lifting assembly 6 and located directly below the through hole 51. The lifting assembly 6 is used to drive the top plate 4 upward and through the through hole 51. The first bracket 1 serves as a support component for the lifting assembly 6, which is fixed to its inner wall. The top plate 4 slides vertically and is located at the output end of the lifting assembly 6. The lifting assembly 6 can move the top plate 4 to the through hole 51 until the top plate 4 pushes out the battery cell above the through hole 51, achieving chip mounting. Simultaneously, the corner plate 7 continuously restricts the corners of the battery cell, ensuring that the battery cell does not wobble.

[0026] Furthermore, the lifting assembly 6 includes a linear actuator 61, a guide post 62, and a lifting plate 63. The linear actuator 61 is mounted on the first bracket 1, and the guide post 62 is slidably disposed on the linear actuator 61. A top plate 4 is mounted on the end of the guide post 62 facing the through hole 51. The output shaft of the linear actuator 61 is connected to the lifting plate 63. The guide post 62 and the lifting plate 63 are used to connect the linear actuator 61 and the top plate 4. When the linear actuator 61 is activated, it drives the lifting plate 63 to rise until the lifting plate 63 drives the top plate 4 upward through the guide post 62 until the top plate 4 extends out of the through hole 51, which is used to lift the battery cell upward to attach the chip.

[0027] The linear actuator 61 can be selected from different actuators, such as using the output shaft of a cylinder or electric cylinder to drive the lifting plate 63 to rise and fall, or using a motor and a lead screw to drive the lifting plate 63 to rise and fall. In this case, the lifting plate 63 needs to be slidably set on the inner wall of the first bracket 1 to ensure its lifting stability.

[0028] like Figure 1 , Figure 3 and Figure 4 As shown, the top plate 4 and the through hole 51 have the same shape and are both cross-shaped. In order to improve the uniformity of the force on the battery cell, they can also be elliptical or parallelogram-shaped. This method is preferred because it considers the versatility of the product and ensures that the battery cells of different sizes can be subjected to uniform force.

[0029] like Figures 1-3 As shown, this application includes a rotating plate 3, with base plates 5 mounted on each edge of the rotating plate 3. A rotary actuator 9 is located in the middle of the rotating plate 3. The rotary actuator 9 drives the base plates 5 to move sequentially above the top plate 4, and a through hole 51 penetrates the rotating plate 3. The rotating plate 3 can be circular, with the base plates 5 arranged sequentially along its edges. Preferably, the rotating plate 3 has a square structure, with the base plates 5 distributed at both ends. When the rotary actuator 9 rotates to adjust the rotating plate 3, it drives the base plates 5 to perform a reversal operation, enabling subsequent cell mounting operations and improving switching efficiency.

[0030] Furthermore, the rotary actuator 9 can be installed on the top of the rotating plate 3, preferably below the rotating plate 3, to avoid interference between the rotary actuator 9 and the patch. The output end of the rotary actuator 9 is fixedly connected to the rotating plate 3. A second bracket 2 is provided at the rotary actuator 9, and the rotary actuator 9 is mounted on the top of the second bracket 2. The second bracket 2 is used to support the rotary actuator 9 and maintain the height difference between the rotary actuator 9 and the top plate 4. The rotary actuator 9 is preferably driven by a motor, but a combination of motor and reducer drive can also be used, such as a combination of motor, worm gear and worm shaft drive. The motor drives the worm gear to rotate through the worm shaft, and the axis of the worm gear is installed in the middle of the rotating plate 3 to achieve smooth rotation.

[0031] like Figure 4As shown, the base plate 5 has grooves 52 at both ends in the first direction. The adjusting block 8 is slidably mounted on the base plate 5 through the grooves 52. Preferably, the grooves 52 are lower than the upper surface of the base plate 5. When the adjusting block 8 slides in the first direction, its middle part extends downward and slides on the grooves 52, increasing the contact area between the adjusting block 8 and the grooves 52 and ensuring the stability of its movement. If it needs to be fixed, it is only necessary to use fasteners such as screws to pass through the grooves 52 until the adjusting block 8 is locked on the base plate 5, thus determining the width of the battery cell. When it is necessary to determine the length of the battery cell, it is only necessary to adjust the position of the angle plate 7 on the adjusting block 8 and then tighten it with screws again.

[0032] Preferably, a slide table 81 is provided on the side of the adjusting block 8 facing the corner plate 7. The corner plate 7 is slidably connected to the adjusting block 8 via the slide table 81. The slide table 81 is a plane and has a groove. The bottom end of the corner plate 7 is slidably connected to the groove via the slide table 81. A stop bar is also provided on one side of the slide table 81 to prevent the corner plate 7 from easily shifting when it abuts against the corner of the battery cell.

[0033] like Figure 4 As shown, the corner plate 7 has an L-shaped cross-section. The L-shaped plate can fit better against the corner of the battery cell to increase the bonding area.

[0034] like Figure 3 As shown, a brush holder 10 and a probe rod 11 are also installed around the base plate 5. The probe rod 11 is used to install a detector to facilitate obtaining the status of the battery cell. A brush can be installed on the brush holder 10 to facilitate cleaning the dust on the release paper of the battery cell during the bonding process.

[0035] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
