Description

Technical Field

[0001] The present invention relates to the technical field of spraying fixtures, and in particular to a UV glue spraying fixture system and method. Background Art

[0002] In the lithium-ion battery manufacturing industry, UV adhesive spraying is a key process step in improving the bond strength between battery components and ensuring waterproof and dustproof performance. However, with the market's increasing demands for lithium-ion battery performance and the increasing diversity of lithium-ion battery models and sizes, traditional fixtures have exposed numerous shortcomings during the UV adhesive spraying process.

[0003] Traditional fixture designs are often customized for specific battery sizes and lack flexibility. When it is necessary to process batteries of different sizes, it is often necessary to replace the fixture or perform tedious manual adjustments, which not only reduces production efficiency but also increases operational complexity and costs. More seriously, traditional fixtures often use rigid contact when clamping batteries and lack the necessary buffering and protection mechanisms. During the clamping process, if the fixture applies excessive pressure to the battery casing, it is likely to cause the battery casing to deform, damage, or even rupture, which will not only reduce the battery's service life and safety, but also increase the scrap rate in the production process.

[0004] The prior art discloses a vertically rotating lithium battery spraying fixture, comprising a fixture and a fixture drive assembly. The fixture is provided with a rotary drive assembly. The fixture comprises an upper clamping portion and a lower clamping portion, which are separately provided. The upper clamping portion is provided directly above the lower clamping portion. The fixture drive assembly is connected to the upper clamping portion and drives the upper clamping portion to move in a vertical direction. The upper clamping portion is provided with a rotatable upper clamping block, and the lower clamping portion is provided with a rotatable lower clamping block. The upper and lower clamping blocks are located on the same axis. The rotary drive assembly is used to drive the upper and / or lower clamping blocks to rotate. This solution is mainly used to clamp cylindrical lithium batteries, but cannot clamp square lithium batteries. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a UV glue spraying fixture system and method, which can achieve flexible and adaptive clamping of lithium battery cells with square cross-sections of different sizes and types, and has a wide range of applications.

[0006] In order to achieve the above object, the present invention is implemented through the following technical solutions: In a first aspect, a UV glue spraying fixture system includes: Rotating platform, used to support the battery cell and drive the battery cell to rotate; Two sets of clamping mechanisms are respectively arranged on both sides of the rotating platform, including a moving platform. A support seat is provided on the top of the moving platform. On one side of the support seat close to the rotating platform, a support plate and at least two sets of laser distance sensors are horizontally arranged. A clamping plate is connected to the support plate through an elastic member. The clamping plate can be close to the side surface of the outer shell of the battery cell to clamp the battery cell. The laser distance sensor is used to detect the distance from the support seat to the battery cell, and the moving platform realizes longitudinal position adjustment through the detection of the laser distance sensor.

[0007] As a further implementation manner, the clamping mechanism includes a first clamping mechanism and a second clamping mechanism. The structures of the first clamping mechanism and the second clamping mechanism are the same and are symmetrically arranged with respect to the rotating platform.

[0008] As a further implementation manner, a chute is horizontally arranged in the support plate and extends to one end of the support plate close to the rotating platform. One end of a cross bar is connected to the bottom of the chute through a spring, and the other end of the cross bar extends out of the chute to be connected to the clamping plate.

[0009] As a further implementation manner, the moving platform is a two-dimensional moving platform and can move in the horizontal and vertical directions. The moving platform moves a set distance horizontally according to the detection by the laser distance sensor, so that the clamping plate clamps on the battery cell and the spring is in a compressed state.

[0010] As a further implementation manner, two sets of laser distance sensors are arranged in parallel and are located below the support plate. The distance between the laser distance sensors is less than the minimum width of the side surface of the outer shell of the battery cell.

[0011] As a further implementation manner, a slider guide pair is provided on the top of the support plate to enable the slider to move horizontally on the support plate. A chute is horizontally arranged in the slider and extends to one end of the slider close to the rotating platform. One end of a cross bar is connected to the bottom of the chute through a spring, and the other end of the cross bar extends out of the chute to be connected to the clamping plate.

[0012] As a further implementation manner, a pressure sensor is provided between the spring and the bottom of the chute. The moving platform can move in the vertical direction to adjust the vertical position of the clamping plate. The slider drives the clamping plate to move horizontally. When the pressure detected by the pressure sensor increases to the set range, the slider stops moving.

[0013] As a further implementation manner, a manipulator is provided on one side of the rotating platform. The manipulator is used to transfer the battery cell to the rotating platform and transfer the battery cell after spraying to the next process.

[0014] As a further implementation manner, a safety light curtain is provided on one side of the rotating platform.

[0015] In a second aspect, a method for operating a UV glue spraying fixture system, using any of the above-described UV glue spraying fixture systems, comprises the following steps: The battery cell is placed on the rotating platform, and the movable platform adjusts its position longitudinally. At the same time, the laser ranging sensor detects the distance to the side of the battery cell. The rotating platform drives the battery cell to rotate so that the distance detected by multiple groups of laser ranging sensors is the same; the clamping plate is controlled to abut the side of the battery cell shell and the elastic part is in a compressed state, and the outer side of the battery cell shell begins to be sprayed; then the rotating platform rotates, and the adjustment process of the movable platform and the rotating platform is repeated. The clamping plate clamps the battery cell again to spray UV glue on different sides of the battery cell shell.

[0016] The beneficial effects of the present invention are as follows: 1. The UV glue spraying fixture system of the present invention can realize flexible clamping of battery cells and can realize adaptive clamping of lithium batteries with square cross-sections of different sizes and types. The emergence of this system will effectively solve the problems of low production efficiency and poor adaptability of traditional fixtures in the UV glue spraying process, and improve the production efficiency and product quality of lithium battery manufacturing.

[0017] 2. The present invention utilizes two sets of laser ranging sensors to detect the battery cells. Combined with the longitudinal movement of the mobile platform, the mobile platform can drive the longitudinal adjustment of the clamping plate so that the clamping plate can be aligned with the side of the battery cell. The spacing between the laser ranging sensors is smaller than the minimum width of the side of the outer shell of the battery cell, achieving precise clamping. The edge of the clamping plate will not exceed the side of the battery cell being clamped, ensuring the spraying effect.

[0018] 3. The present invention utilizes two sets of laser ranging sensors to detect the battery cells, in conjunction with the rotation of the rotating platform. When the two sets of laser ranging sensors detect the same distance to the battery cells, it indicates that the side of the battery cells is facing the support seat, and then the clamping action can be performed to prevent the battery cells from tilting when placed on the rotating platform, which would affect the clamping effect.

[0019] 4. The present invention utilizes a pressure sensor to determine the clamping state and achieve better flexible clamping of the battery cell; the clamping plate and the cross bar are detachably connected, and clamping plates of different sizes can be installed according to the size of the battery cell.

[0024] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further descriptions of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those of ordinary skill in the technical field to which the present invention belongs.

[0025] Embodiment 1 In a typical implementation manner of the present invention, referring to Figure 1 - Figure 2 as shown, a UV glue spraying fixture system includes a rotating platform 4 and two groups of clamping mechanisms. The rotating platform 4 is arranged between the two groups of clamping mechanisms. The rotating platform 4 and the two groups of clamping mechanisms are arranged in the transverse direction. The rotating platform 4 is used to support the battery cell and drive the battery cell to rotate. The output ends of the two groups of clamping mechanisms move towards each other to clamp the opposite sides of the outer shell of the battery cell 3.

[0026] It can be understood that the purpose of the rotating platform 4 driving the battery cell 3 to rotate is to enable the clamping mechanism to clamp different opposite sides of the battery cell 3, so as to perform UV glue spraying on multiple sides of the battery cell.

[0027] In this embodiment, the two groups of clamping mechanisms are respectively arranged on both sides of the rotating platform 4, and include a moving platform 11. A support base 12 is arranged on the top of the moving platform 11. A support plate 13 and at least two groups of laser distance sensors 5 are horizontally arranged on the side of the support base 12 close to the rotating platform 4. The clamping plate 15 is connected to the support plate 13 through an elastic member. The clamping plate 15 can be close to the side of the outer shell of the battery cell 3 to clamp the battery cell 3; the laser distance sensor 5 is used to detect the distance from the support base 12 to the battery cell 3, and the moving platform 11 realizes longitudinal position adjustment through the detection of the laser distance sensor 5.

[0028] The clamping mechanism includes a first clamping mechanism 1 and a second clamping mechanism 2. In this embodiment, the structure of the first clamping mechanism 1 will be described. The structures of the first clamping mechanism 1 and the second clamping mechanism 2 are the same and are symmetrically arranged with respect to the rotating platform.

[0029] As Figure 1 and Figure 2 shown, the structure of the first clamping mechanism 1 includes a moving platform 11, a support base 12, a support plate 13, a cross bar 14, a clamping plate 15, a spring 16, and a chute 17.

[0030] The moving platform 11 is a set of platform plates. A support base 12 is provided at the middle position on the top surface of the moving platform 11 close to the rotating platform 4. The support base 12 is a cubic structure. Taking Figure 1 and Figure 2 the view direction as an example, the right end face of the support base 12 is flush with the right end face of the moving platform 11. In this embodiment, the left - right direction is taken as the transverse direction, and the front - back direction is taken as the longitudinal direction for description.

[0031] The support plate 13 is provided at a position close to the top end of the right end face of the support base 12. The support plate 13 is arranged horizontally and is perpendicular to the right end face of the support base 12.

[0032] A chute 17 is horizontally provided inside the support plate 13. The chute 17 extends to the end face (right end) of the support plate 13 close to the rotating platform 4. One end of the cross bar 14 is connected to the bottom of the chute 17 (left end of the chute 17) through a spring 16. The cross bar 14 can slide horizontally in the chute 17, and the other end of the cross bar 14 extends outside the chute 17 and is connected to the clamping plate 15.

[0033] As Figure 1 shown, two groups of laser distance sensors 5 are arranged in parallel and are located on the right end face of the support base 12 directly below the support plate 13. The distance between the laser distance sensors 5 is less than the minimum width of the side surface of the outer shell of the battery cell.

[0034] The moving platform 11 in this embodiment is a two - dimensional moving platform and can move in the transverse and longitudinal directions. The purpose of the moving platform 11 moving in the longitudinal (Y - axis) direction is to longitudinally adjust the clamping point of the clamping plate 15 through the support base 12, the support plate 13, and the cross bar 14.

[0035] The purpose of the moving platform 11 moving in the longitudinal (X - axis) direction is to drive the clamping plate 15 to approach the battery cell for clamping. The moving platform moves a set distance horizontally according to the detection by the laser distance sensors 5, so that the clamping plate 15 clamps on the battery cell and the spring is in a compressed state.

[0036] After placing the battery cell 3 on the rotating platform 4, if both groups of laser distance sensors 5 can detect the distance from the battery cell 3, but the two distance data are different, it indicates that the side of the outer shell of the battery cell 3 close to the support base 12 and the right end face of the support base 12 are not in a parallel state. At this time, the control unit of the system controls the rotating platform 4 to rotate until the side of the outer shell of the battery cell 3 close to the support base 12 and the right end face of the support base 12 are parallel, and the error between the two distance data (the error caused by the flatness of the outer side of the battery cell housing) is within the set range. Next, the clamping action of the clamping plate 15 can be carried out.

[0037] If one group or both groups of laser distance sensors 5 cannot detect the battery cell, it means that the laser distance sensors 5 and the battery cell are not in the same horizontal direction. At this time, the control unit controls the moving platform 11 to move and adjust along the Y-axis until both groups of laser distance sensors 5 can detect the battery cell and then stops. The distance between the laser distance sensors 5 in this embodiment is less than the minimum width of the side of the outer shell of the battery cell, and the purpose is to enable the clamping plate 15 to accurately clamp the side of the battery cell, and the clamping plate will not exceed the range of the outer shell side, ensuring the spraying effect.

[0038] After the laser distance sensor 5 obtains the distance from the side of the outer shell of the battery cell close to the support base 12, the control unit can calculate the distance from the clamping plate to the side of the outer shell of the battery cell, and the moving platform can drive the clamping plate to clamp the opposite side of the battery cell.

[0039] It can be understood that the horizontal movement distance of the moving platform 11 is the sum of the distance from the clamping plate 15 to the side of the outer shell of the battery cell and the compression length of the spring 16. The compression length of the spring 16 needs to be input into the control unit, and it is appropriate that the length of the spring 16 becomes half of its natural state. As an elastic member, after the clamping plate 15 clamps the battery cell 3, the spring 16 can achieve flexible clamping of the battery cell 3, and will not cause deformation, damage or even rupture of the battery shell due to rigid clamping.

[0040] In a preferred example, a pressure sensor can be arranged between the bottom of the groove and the spring 16. When the moving platform 11 drives the clamping plate to perform the clamping action, when the pressure of the pressure sensor 181 rises to the specified range, the moving platform 11 stops its horizontal movement. The principle of this clamping process is similar to the principle of setting the compression length of the spring.

[0041] It can be understood that a manipulator is provided on one side of the rotating platform 4. The manipulator is used to transfer the battery cell 3 onto the rotating platform 4 and transfer the sprayed battery cell to the next process. The manipulator is a prior art.

[0042] A safety light curtain is also provided on one side of the rotating platform 4 to play a protective role and prevent the operator's hand or body from accidentally entering the dangerous area, such as the working range of the robotic arm. When the light curtain is blocked, the system will immediately trigger an emergency stop to avoid personnel injury. The specific layout of the safety light curtain can be determined comprehensively according to the positions of other mechanisms.

[0043] It is understandable that the clamping plate 15 and the cross bar 14 are detachably connected, and the clamping plate 15 can be replaced to install clamping plates 15 of different sizes. In addition, the clamping plate 15 can be connected to the cross bar in the form of a ball hinge.

[0044] The clamping surface of the clamping plate 15 can be provided with a flexible material, such as a rubber pad, to better protect the battery cell.

[0045] The UV glue spraying fixture system of this embodiment can achieve flexible clamping of the battery cell, and can achieve adaptive clamping of lithium batteries with square cross-sections of different size types. The appearance of this system will effectively solve the problems of low production efficiency and poor adaptability existing in the traditional fixture during the UV glue spraying process, and improve the production efficiency and product quality of lithium battery manufacturing.

[0046] Embodiment 2 In a typical implementation manner of the present invention, refer to Figure 3 - Figure 4 As shown, a UV glue spraying fixture system, which is different from that of Embodiment 1 in that the moving platform 11 is different and the structure of the support plate 13 is different.

[0047] Specifically, the moving platform 11 of this embodiment can only move in the longitudinal direction to adjust the longitudinal position (clamping position) of the clamping plate, and the moving platform 11 cannot move horizontally. The horizontal movement of the clamping plate is realized through the slider guide rail pair provided on the support plate 13.

[0048] Such as Figure 3 and Figure 4 , the support plate 13 of this embodiment is different from the support plate 13 of Embodiment 1. The support plate 13 of this embodiment does not have a chute inside, and it is provided with a slider guide rail pair on the top to enable the slider to move horizontally on the support plate.

[0049] Specifically, the motor 132 is arranged at one end of the top surface of the support plate 13 close to the support seat 12. The output end on the right side of the motor 132 is connected to the horizontally arranged threaded rod 19. The other end of the threaded rod 19 is close to the right end position of the support plate 13. A fixed seat 131 is arranged on the top surface at the right end position of the support plate 13, and the right end of the threaded rod 19 is in cooperation with the fixed seat 131 through a bearing.

[0050] The top of the support plate 13 is also provided with a slide rail, and the slider 18 is in cooperation with the slide rail. The slider 18 is also in cooperation with the threaded rod 19. The motor 132 drives the threaded rod 19 to rotate, and the horizontal movement of the slider 18 on the slide rail can be realized.

[0051] Such as Figure 4As shown in the figure, a chute 17 is horizontally arranged inside the slider 18, and the chute 17 extends to one end of the slider 18 close to the rotary platform 4. One end of a cross bar 14 is connected to the bottom of the chute 17 through a spring 16, and the other end of the cross bar 14 extends outside the chute 17 to be connected to a clamping plate 15.

[0052] After the longitudinal position of the moving platform 11 is adjusted, the motor drives the slider to move horizontally, so that the clamping plate approaches the cell housing. According to the distance from the laser distance sensor to the side of the cell, the control unit can calculate the distance that the slider needs to move horizontally based on the structural dimensions of each structure of the clamping mechanism. When the spring 16 is compressed to a set degree, the clamping action is completed.

[0053] It can be understood that, as Figure 4 shown, a pressure sensor 181 is arranged between the spring 16 and the bottom of the chute 17; when the slider 18 drives the clamping plate to move horizontally, when the pressure detected by the pressure sensor 181 increases to a set range, the control unit controls the slider 18 to stop moving, and the clamping action is completed.

[0054] In this embodiment, the rotary platform 4 and the moving platform 11 in Embodiment 1 are both conventional technologies in the mechanical field. Those skilled in the art can select corresponding structural components according to the situation as long as the moving platform can be translated and the rotary platform can be rotated.

[0055] Embodiment 3 In a typical implementation manner of the present invention, a working method of a UV glue spraying fixture system adopts the UV glue spraying fixture system described in Embodiment 1 or Embodiment 2, and includes the following steps: The manipulator places the cell on the rotary platform 4. The laser distance sensor 5 detects the distance from the side of the cell. At the same time, the longitudinal position of the moving platform 11 is adjusted so that both groups of laser distance sensors 5 can detect the side of the cell. The rotary platform 4 drives the cell 3 to rotate so that the distances detected by multiple groups of laser distance sensors 5 are the same. At this time, the support base 12 is parallel to the side of the cell, and then the clamping action of the clamping plate 15 can be performed.

[0056] As Figure 1 and Figure 2 shown, the control unit can calculate the distance that the moving platform 11 moves towards the cell 3 according to the distance from the laser distance sensor 5 to the side of the cell 3 and the structural dimensions and relative positions of each structure of the clamping mechanism in the natural state, and then controls the moving platform 11 of the first clamping mechanism 1 and the second clamping mechanism 2 to approach the cell, so as to realize that the clamping plate 15 clamps the opposite sides of the cell housing.

[0057] After clamping, Figure 2 the clamping plate 15 in

[0058] As Figure 3 - Figure 4 shown, according to the distance to the side of the battery cell detected by the laser ranging sensor 5 and the structural dimensions and relative positions of each structure in the natural state of the clamping mechanism, the control unit can calculate the lateral movement distance of the slider 18, so that after the clamping plate 15 clamps the battery cell, Figure 4 the spring 16 in Figure 4 is in a compressed state, realizing flexible clamping of the battery cell. The pressure sensor 181 in

[0059] can be used as a criterion for judging the clamping state. When the pressure detected by the pressure sensor 181 reaches the set value, it means that the clamping state is completed at this time, and the slider 18 stops lateral movement. After the battery cell 3 is clamped, the UV glue spraying mechanism on one side of the rotating platform starts to spray the outer side of the battery cell 3 housing. Then the clamping mechanism exits the clamping state, the rotating platform 4 rotates, switches the glue spraying surface, repeats the adjustment process of the moving platform 11 and the rotating platform 4, and the clamping plate 15 clamps the battery cell again to realize spraying UV glue on different sides of the battery cell housing.

[0060] It can be understood that a rapid curing light source is provided on one side of the rotating platform 4, which can realize rapid curing of the sprayed UV glue on the battery cell housing, so as not to affect subsequent clamping. The rapid curing light source is a prior art, as long as it can realize rapid curing of the UV glue.

[0061] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
