[0043] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0044] In order to facilitate understanding of the carrier and passivation equipment for the passivation device provided by the utility model, the application background is first explained. Laser scribing makes it easy for the photogenerated carriers generated by the photoelectric effect to recombine at the edge, affecting the electrical properties of the cell and causing power loss in the packaging of the cell to the component. Therefore, it is generally necessary to passivate the cut edges of the cell to compensate for the power loss of the cell, and a carrier is required to load the cell during the passivation process.

[0045] In the related art, the carrier is generally configured as a box-shaped structure with an opening on one side and a pressure plate on the top. After the battery cells are placed into the carrier from the opening, the battery cells are elastically pressed by the pressure plate on the top to achieve loading of the battery cells.

[0046] However, in actual applications, considering that the thickness of battery cells of different specifications may be different, the number of battery cells loaded in a single passivation process may also be different. When using the above-mentioned carrier, it is difficult to adaptively adjust the degree of compression of the battery cell by the pressure plate. Too little compression force may affect the passivation effect, and too much compression force may crush the battery cell, resulting in limited applicability of the carrier.

[0047] Based on the above, the utility model provides a carrier for a passivation device and a passivation device, which can adjust the degree of compaction of materials and improve applicability.

[0048] Combine the following Figure 1-Figure 3 The utility model describes a carrier for a passivation device and a passivation device.

[0049] Reference Figure 1 and Figure 2 , a carrier for passivation equipment, comprising a material box 1, a cover plate 2, a pressing piece 3 and an adjusting piece 4; wherein, a cavity is provided inside the material box 1, and openings are provided on its side and top, materials can enter and exit the material box 1 through the opening on the side of the material box 1, and the pressing piece 3 can be placed in the material box 1 through the opening on the top of the material box 1; the cover plate 2 is detachably covered on the top opening of the material box 1; the pressing piece 3 is located in the material box 1 and cooperates with the cover plate 2 through an elastic piece 5 to elastically compress the material in the material box 1; the adjusting piece 4 is suitable for adjusting the deformation of the elastic piece 5 to adjust the pressure applied to the material by the pressing piece 3.

[0050] In actual applications, materials such as battery cells are stacked in the material box 1 through the opening on the side of the material box 1, and then the cover plate 2 is covered on the top of the material box 1, and the elastic member 5 undergoes elastic deformation, and the pressing member 3 is pushed to elastically compress the battery cells under the action of the elastic member 5 to achieve the loading of the battery cells; based on actual process requirements, when it is necessary to replace battery cells of different specifications or adjust the loading number of battery cells in a single passivation process, the overall thickness of the battery cells in the material box 1 may change. At this time, the deformation of the elastic member 5 can be adjusted by the adjusting member 4, thereby adjusting the elastic force applied by the elastic member 5 to the pressing member 3, and then adjusting the pressure applied by the pressing member 3 to the battery cells, so as to achieve different degrees of compression of the battery cells and ensure the passivation effect. At the same time, it is effectively avoided that the battery cells are crushed by excessive pressure, thereby improving the applicability of the carrier.

[0051] In some embodiments, the elastic member 5 has a variety of selectable structures or forms, such as a spring, an elastic sheet, or other elements with an elastic modulus, which can be selected according to actual process requirements and application scenarios.

[0052] In this embodiment, the elastic member 5 is a compression spring, which is arranged between the cover plate 2 and the pressing member 3, and the bottom end of the compression spring elastically abuts against the pressing member 3 to apply elastic force to the pressing member 3; the adjusting member 4 includes an adjusting portion 40 and a positioning structure 41; wherein the adjusting portion 40 is connected to the cover plate 2, the compression spring is arranged between the adjusting portion 40 and the pressing member 3, and the adjusting portion 40 can move in a direction close to or away from the pressing member 3; the positioning structure 41 is used to locate the position of the adjusting portion 40.

[0053] In practical applications, by moving the adjusting member 4 closer to the pressing member 3, the deformation of the compression spring can be increased, and the elastic force applied by the compression spring to the pressing member 3 becomes larger, thereby increasing the pressure of the pressing member 3 on the battery cell; by moving the adjusting member 4 away from the pressing member 3, the deformation of the compression spring can be reduced, and the elastic force applied by the compression spring to the pressing member 3 becomes smaller, thereby reducing the pressure of the pressing member 3 on the battery cell.

[0054] In order to avoid radial deformation of the compression spring during adjustment, which may affect the adjustment effect, refer to Figure 2 The adjusting member 4 also includes a guide column 42, which is slidably inserted into the cover plate 2 and has its bottom end fixedly connected to the pressing member 3, a compression spring is sleeved outside the guide column 42, and the adjusting portion 40 is a sleeve-shaped structure with openings at both ends, and the adjusting portion 40 is sleeved outside the guide column 42 and slidably cooperates with the guide column 42.

[0055] The guide column 42 can limit and guide the compression spring during the deformation process, effectively avoiding the problem of radial deformation of the compression spring and ensuring the adjustment effect.

[0056] In some optional embodiments, the adjustment portion 40 and the cover plate 2 may cooperate in different ways. For example, the cover plate 2 may be slidably connected to the top of the material box 1, and the adjustment portion 40 is fixedly connected to the cover plate 2. By moving the cover plate 2 as a whole closer to or away from the pressing member 3, the adjustment portion 40 is moved closer to or away from the pressing member 3, thereby achieving adjustment of the compression spring force. For another example, the cover plate 2 may also be fixedly connected to the top of the material box 1, and the adjustment portion 40 is slidably connected to the cover plate 2. In this way, the compression spring force can be adjusted by only sliding the adjustment portion 40 relative to the cover plate 2 to move closer to or away from the pressing member 3.

[0057] In this embodiment, the cover plate 2 is fixedly connected to the top of the material box 1; the adjusting part 40 is slidably arranged on the cover plate 2, and the bottom end of the adjusting part 40 is elastically abutted against the other end of the compression spring relative to the pressing member 3. By sliding the adjusting part 40 relative to the cover plate 2 to approach or move away from the pressing member 3, the elastic force of the compression spring is adjusted.

[0058] In order to facilitate the positioning of the adjusting part 40 , the positioning structure 41 includes a nut which is threadedly connected to the other end of the guide column 42 relative to the pressing member 3 and is suitable for abutting against the other end of the adjusting part 40 relative to the compression spring.

[0059] With such a configuration, after the pressing member 3 presses the battery cell, the distance between the adjusting portion 40 and the pressing member 3 can be changed by screwing the nut, thereby adjusting the elastic force of the compression spring. When the pressure of the pressing member 3 is small, the nut is screwed in the direction close to the pressing member 3 to drive the adjusting portion 40 to move in the direction close to the pressing member 3, and the deformation of the compression spring increases, thereby increasing the pressure applied by the pressing member 3 to the battery cell. When the pressure of the pressing member 3 is large, the nut is screwed in the direction away from the pressing member 3, and the compression spring drives the adjusting portion 40 to move in the direction away from the pressing member 3, and the deformation of the compression spring decreases, thereby reducing the pressure applied by the pressing member 3 to the battery cell.

[0060] Of course, the adjusting member 4 includes but is not limited to the structures listed above, and any adjusting member 4 with other structures or forms as long as it can adjust the deformation amount of the elastic member 5 is applicable.

[0061] Specifically, a positioning block 20 is fixedly connected to the side of the cover plate 2 facing away from the pressing member 3. The positioning block 20 and the cover plate 2 can be connected in a variety of optional ways, such as welding or connecting parts such as bolts; in this embodiment, the positioning block 20 is fixedly connected to the cover plate 2 by bolts. The positioning blocks 20 are arranged in pairs, and each pair of positioning blocks 20 is provided with positioning holes 200 at corresponding positions, so as to facilitate the overall grasping of the cover plate 2 and the pressing member 3.

[0062] Through the above-mentioned adjustment member 4, the pressure applied by the pressing member 3 to the battery cell can be adjusted to improve the applicability of the carrier. In practical applications, the battery cells need to be placed in a stacked manner in the material box 1. The flatness of the stacking between the battery cells and the accuracy of the positioning of the pressing member 3 are particularly important. By stacking the battery cells flat and centering the pressing member 3, the battery cells can be evenly stressed and the problem of fragments can be effectively avoided.

[0063] In order to achieve the above purpose, refer to Figure 1 The carrier also includes a tray 6, which is detachably arranged at the bottom of the material box 1. In practical applications, the tray 6 can be taken out of the material box 1 by a robot, and then the battery cells are neatly stacked in the tray 6 at an automated station, and then the tray 6 is placed in the material box 1 by a robot, so that multiple battery cells can be automatically grasped and placed as a whole, effectively avoiding the winding caused by the stacking misalignment between battery cells.

[0064] Specifically, a clearance groove 60 is provided between the bottom of the tray 6 and the bottom surface of the material box 1. The clearance groove 60 extends from the side opening of the material box 1 to the inside of the material box 1. The clearance groove 60 can provide clearance for the robot arm, so that the robot arm can insert into the bottom of the tray 6 to take the tray 6 out of the material box 1 or place it into the material box 1.

[0065] Specifically, the clearance groove 60 is formed by splicing two parts, one part is opened on the bottom surface of the tray 6, and the other part is opened on the bottom wall of the material box 1.

[0066] In order to solve the problem of centering the pressing piece 3, refer to Figure 1 The cover plate 2 and the top of the material box 1 are spliced ​​together through a tongue and groove. The tongue and groove can realize the precise positioning of the cover plate 2 and the material box 1. Since the pressing member 3 is connected to the cover plate 2, the pressing member 3 can be accurately aligned, which effectively avoids the problem of fragmentation caused by uneven force on the battery cell.

[0067] In order to facilitate the connection between the cover plate 2 and the material box 1, refer to Figure 1 and Figure 3 The carrier also includes a locking mechanism 7 for locking the material box 1 and the cover plate 2.

[0068] Specifically, the locking mechanism 7 is fixedly connected to the outer wall of the material box 1; the locking mechanism 7 includes a locking pin 70, and the locking pin 70 includes two states: extended and retracted. In the extended state, the locking pin 70 is pressed against the side of the cover plate 2 away from the pressing member 3, thereby pressing and fixing the cover plate 2 to the top of the material box 1; in the retracted state, the locking pin 70 is disengaged from the cover plate 2, so as to facilitate the removal of the cover plate 2 from the material box 1.

[0069] In a specific embodiment, referring to Figure 3The locking mechanism 7 also includes a mounting seat 71 and a mounting portion 72; wherein the mounting seat 71 is suitable for being fixedly connected to the outer wall of the material box 1; the mounting portion 72 is fixedly connected to the mounting seat 71, and a slide groove is provided on the mounting portion 72, and the locking pin 70 is slidably connected to the slide groove. By sliding the locking pin 70 in the slide groove, the locking pin 70 is switched between the extended and retracted states.

[0070] The mounting portion 72 may be configured as an integrally formed structure, or may be formed by splicing at least two parts to facilitate the assembly of the locking mechanism 7 , and the specific selection may be made according to actual needs.

[0071] In this embodiment, the mounting portion 72 includes a fixed block 720 and a pressing block 721 that are spliced ​​with each other; wherein the fixed block 720 is fixedly connected to the mounting seat 71, and the pressing block 721 is detachably connected to the fixed block 720 as a whole through connecting elements such as screws, and a slide groove is opened between the fixed block 720 and the pressing block 721. Such a configuration can facilitate the assembly of the locking pin 70.

[0072] Specifically, the slide groove passes through the two opposite sides of the mounting portion 72, and the locking pin 70 is inserted into the slide groove. The locking pin 70 includes a first end and a second end. After the locking mechanism 7 is connected to the material box 1, the first end faces inward and is suitable for pressing the cover plate 2. A shift block 73 is fixedly connected to the second end. Through the shift block 73, the locking pin 70 can be connected to a linear drive element such as a cylinder, an oil cylinder, or an electric push rod, which is conducive to realizing automation.

[0073] Specifically, a pressing head 700 is protruded from the bottom of the first end, and the end surface of the pressing head 700 facing away from the shift block 73 is an inclined surface, which is inclined downward from the first end to the second end. After the locking pin 70 is extended, the pressing head 700 abuts against the upper surface of the cover plate 2, thereby pressing and fixing the cover plate 2 to the top of the material box 1.

[0074] Specifically, a receiving groove is provided on one side of the mounting portion 72 close to the first end. The receiving groove is located at the bottom of the slide groove and is connected to the slide groove. The position of the receiving groove corresponds to the position of the pressing head 700 and is used to accommodate the pressing head 700. When the locking pin 70 is in a retracted state, the pressing head 700 is received in the receiving groove to avoid interference with the installation and removal of the cover plate 2.

[0075] It is understandable that the locking mechanism 7 includes but is not limited to the structures listed above, and other structures or forms of locking mechanisms 7 are applicable as long as they can lock the cover plate 2 on the material box 1.

[0076] The passivation device provided by the present invention is described below. The passivation device described below and the carrier for the passivation device described above can refer to each other.

[0077] A passivation device comprises the above-mentioned carrier for the passivation device for loading materials.

[0078] The novelty of the present utility model is that materials such as battery cells are stacked in the material box 1 through the opening on the side of the material box 1, and then the cover plate 2 is closed on the top of the material box 1, the elastic member 5 undergoes elastic deformation, and the pressing member 3 is pushed to elastically press the battery cells under the action of the elastic member 5, so as to realize the loading of the battery cells; based on actual process requirements, when it is necessary to replace battery cells of different specifications or adjust the loading number of battery cells in a single passivation process, the overall thickness of the battery cells in the material box 1 may change. At this time, the deformation amount of the elastic member 5 can be adjusted by the adjusting member 4, thereby adjusting the elastic force applied by the elastic member 5 to the pressing member 3, and then adjusting the pressure applied by the pressing member 3 to the battery cells, so as to realize different degrees of compression of the battery cells, ensure the passivation effect, and effectively avoid crushing the battery cells due to excessive pressure, thereby improving the applicability of the carrier.
