Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cell manufacturing technology, specifically to a vertical carrier plate for fixing solar cells. Background Technology

[0002] Among existing photovoltaic cell manufacturing technologies, heterojunction cells are hailed as the next-generation high-efficiency battery technology with the greatest industrial potential due to their advantages such as high conversion efficiency, short process flow, thin silicon wafer application, low temperature coefficient, and bifacial power generation. Chemical Vapor Deposition (CVD) is the core process for heterojunction cell fabrication. Currently, there are two main heterojunction amorphous silicon thin film deposition technologies: PECVD (Plasma Enhanced CVD) and HWCVD (Hot Wire CVD). HWCVD offers advantages such as simple equipment structure, fast deposition rate, smooth film surface, and low radiation damage; however, it requires a vertical carrier plate for film transfer.

[0003] Currently, suction cups or grippers are commonly used to place solar cells into the grids (cavities) on the carrier plate. Vertical carrier plates also require suction cups or grippers to place the solar cells into the cavities. In order to prevent the solar cells from falling out during the transfer of vertical carrier plates, a blocking mechanism needs to be added to the carrier plate to prevent them from falling out. However, the blocking mechanism in the existing vertical carrier plates has a complicated opening method and the blocking effect on the solar cells is generally not good, which easily leads to the solar cells falling out and causing more fragments. Utility Model Content

[0004] The purpose of this utility model is to address the problems of complex opening methods and easy falling of battery cells caused by the blocking mechanism in existing vertical carrier plates. A vertical carrier plate that can fix the battery cells is designed. The blocking mechanism in the vertical carrier plate not only has a simple opening and closing action, but also effectively blocks the battery cells in the carrier plate to prevent them from falling and causing fragments, thereby reducing fragments and lowering costs.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] This utility model designs a vertical carrier plate for fixing battery cells, which includes the following structural configuration:

[0007] The carrier plate body has a first direction and a second direction that are perpendicular to each other, and has a first end and a second end that are opposite to each other. The carrier plate body also has a number of cavities arranged in a matrix for placing the battery cells.

[0008] Several blocking mechanisms are arranged parallel to the second direction on the carrier plate body. They have open or locked positions (when the blocking mechanism is in the open state, the battery cell can be placed into the cavity by suction cup or gripper; when it is in the locked state, the blocking mechanism blocks the battery cell in the cavity to prevent it from falling out of the cavity).

[0009] Several reset mechanisms are connected to the carrier plate body and the blocking mechanism to keep the blocking mechanism locked in a locked position without external force, so as to block the battery cells placed in the cavity and prevent them from falling off.

[0010] And an electromagnet, which is disposed near the first or second end of the carrier plate body, is used to magnetically attract the blocking mechanism so that it is in an open position to place the battery cell into the cavity.

[0011] Furthermore, a vertical carrier plate for fixing battery cells: the blocking mechanism includes the following structural configuration:

[0012] A first connecting rod is arranged parallel to the second direction above the carrier plate body and is elastically connected to the carrier plate body through several reset mechanisms. The first connecting rod has a length matching the carrier plate body in the second direction. The electromagnet is used to magnetically attract the first connecting rod.

[0013] The second link is provided at least once. One end of the second link is rotatably connected to the first link, and the other end is rotatably connected to the carrier plate body. When the blocking mechanism is in the locked position, the second link is parallel to the first direction.

[0014] And several stop pins, which are detachably mounted on the first connecting rod, for blocking or not blocking the battery cells in the cavity.

[0015] Furthermore, a vertical carrier plate for fixing battery cells is provided: the second connecting rod is provided as two rods, which are respectively positioned near the first end and the second end of the carrier plate body.

[0016] Furthermore, a vertical carrier plate for fixing battery cells is provided: the blocking mechanism further includes a third link, the two ends of which are rotatably connected to the ends of the second link away from the first link. Specifically, the third link further increases the structural stability of the blocking mechanism.

[0017] Furthermore, in a vertical carrier plate for fixing battery cells, when the blocking mechanism is in the open position, the distance between the blocking pin and the battery cell in the first direction is set to 0.3–0.5 mm. Specifically, when the blocking mechanism is in the open position, the blocking pin is no longer above the cavity and will not obstruct the cavity.

[0018] Furthermore, a vertical carrier plate for fixing battery cells: when the blocking mechanism is in the locked position, the distance between the end face of the blocking pin near the battery cell and the battery cell is set to 0.1 to 1.0 mm.

[0019] Furthermore, a vertical carrier plate for fixing battery cells: the reset mechanism includes the following structural configuration:

[0020] The first spring sleeve is fixedly mounted on the carrier plate body;

[0021] The second spring sleeve is fixedly mounted on the first connecting rod;

[0022] The system also includes a spring component, with its two ends connected to the first spring sleeve and the second spring sleeve, respectively. Specifically, the spring component enables an elastic connection between the first connecting rod (reset mechanism) and the carrier plate body. After the electromagnet is de-energized, the spring component causes the first connecting rod to return to its initial position, which in turn causes the stop pin on it to return to its position above the cavity, thereby blocking the battery cells in the cavity and preventing them from falling out of the cavity and causing fragments.

[0023] The beneficial effects of this utility model are:

[0024] (1) The vertical carrier plate for fixing battery cells designed in this utility model has a simple structure and a simple opening method for the blocking mechanism. It only needs to be energized by an electromagnet to magnetically attract the first connecting rod to realize the opening function of the blocking mechanism. It overcomes the problem of the complex opening method of the existing blocking mechanism, thereby improving the battery cell loading efficiency, that is, improving the production efficiency.

[0025] (2) The vertical carrier plate for fixing battery cells designed in this utility model has a simple locking mechanism. Its "self-locking function" is entirely achieved by its own structure, without relying on external power sources such as electricity or air. Only the electromagnet needs to be de-energized; under the action of the reset mechanism (spring component), the first connecting rod can reset, and the stop pin on it can then block the battery cell in the cavity, thus locking the battery cell and effectively preventing it from falling out of the cavity, thereby reducing battery cell fragmentation. The "self-locking function" of this vertical carrier plate for fixing battery cells is fully automated during the operation of the coating equipment. Except for the normal replacement of easily damaged and consumable parts, no manual intervention is required, resulting in a high degree of automation and improved production efficiency.

[0035] Example 1

[0036] like Figures 1-4 As shown, this embodiment 1 designs a vertical carrier plate for fixing battery cells, which includes the following specific structural configuration:

[0037] The carrier plate body 1 has a first direction and a second direction that are perpendicular to each other. The two ends of the carrier plate body 1 in the second direction are respectively a first end 11 and a second end 12 facing each other. The carrier plate body 1 also has a plurality of cavities 13 arranged in a matrix for placing the battery cells 5 (for example, the carrier plate body 1 of this embodiment 1 has 12 cavities arranged in a matrix, such as...). Figure 1 (as shown);

[0038] The blocking mechanism 2 consists of six sets, including a first connecting rod 21, two second connecting rods 22, a third connecting rod 23, and several detachable stop pins 24 mounted on the first connecting rod 21. The first connecting rod 21 is mounted on the carrier plate body 1 parallel to the second direction. The blocking mechanism 2 (i.e., the first connecting rod 21 / stop pins 24) has an open or locked position. When the blocking mechanism 2 is in the open state, it can automatically grasp the battery cell 5 and place it into the cavity 13 using a suction cup or gripper-type gripping method. When it is in the locked state, the blocking mechanism 2 can block the battery cell 5 in the cavity 13 to prevent it from falling out.

[0039] A plurality of reset mechanisms 3 are provided, including a first spring sleeve 31, a second spring sleeve 32 and a spring member 33. The first spring sleeve 31 is fixedly mounted on the carrier plate body 1, the second spring sleeve 32 is fixedly mounted on the first connecting rod 21, and the two ends of the spring member 33 are respectively connected to the first spring sleeve 31 and the second spring sleeve 32 (that is, the first connecting rod 21 is elastically connected to the upper part of the carrier plate body 1 through the spring member 33). The reset mechanism 3 (spring member 33) is used to keep the first connecting rod 21 (stop pin 24) locked (i.e., keep the initial) position state without the action of external force, so as to block the battery cell 5 placed in the cavity 13 and prevent it from falling out of the cavity 13.

[0040] And an electromagnet 4, which is located near the first end 11 of the carrier plate body 1, is used to magnetically attract the blocking mechanism 2 so that it is in the open position. At this time, the battery cell 5 can be placed into the cavity 13 by an automated method of suction cup or gripper.

[0041] The blocking mechanism 2 includes the following specific structural configuration:

[0042] The first connecting rod 21 is elastically connected to the upper part of the carrier plate body 1 via the elastic element 22 along the second direction. The length of the first connecting rod 21 matches the length of the carrier plate body 1 in the second direction. When the electromagnet 4 is energized, it can attract the first connecting rod 21.

[0043] The second link 22 is configured as two links, which are respectively located near the first end 11 and the second end 12 of the carrier plate body 1. One end of the second link 22 is rotatably connected to the first link 21 through the pin 25, and the other end is rotatably connected to the carrier plate body 1 through the positioning pin 26. When the first link 21 is locked, the second link 22 is parallel to the first direction.

[0044] The third link 23 is disposed above the carrier plate body 1 along the second direction, specifically its two ends are rotatably connected to the end of the second link 22 that is away from the first link 21.

[0045] And a number of stop pins 24, which are detachably disposed on the first connecting rod 21, are used to block the battery cell 5 in the cavity 13 when the blocking mechanism 2 is in the locked state, and do not block the battery cell 5 in the cavity 13 when the blocking mechanism 2 is in the open state.

[0046] Specifically, when the blocking mechanism 2 is in the open position, the distance between the blocking pin 24 and the battery cell 5 in the first direction is set to 0.3 to 0.5 mm; when the blocking mechanism 2 is in the locked position, the distance between the end face of the blocking pin 24 near the battery cell 5 and the battery cell 5 is set to 0.1 to 1.0 mm.

[0047] Specifically, the blocking mechanism 2 set in the above embodiment 1 can be regarded as a linkage mechanism. After the first linkage 21 is attracted by the magnetic force of the electromagnet 4, it will swing around the rotation connection point between the second linkage 22 and the carrier plate body 1 (i.e., the positioning pin 26) as the fulcrum, so that the blocking pin 24 is no longer above the cavity 13 and will not block the cavity 13. At this time, the blocking mechanism 2 becomes open, and the battery cell 5 can be placed into the cavity 13 by an external suction cup or gripper type automatic gripping method.

[0048] Specifically, in the vertical carrier plate designed in Embodiment 1 above, when it is necessary to place the battery cell 5 into the cavity 13 of the vertical carrier plate: First, the vertical carrier plate is rotated to a horizontal position. Then, the electromagnet 4 is used to magnetically attract the first connecting rod 21 to form a pulling force (this pulling force can overcome the elastic force of the spring 33), thereby causing the stop pin 24 to move away from the top of the cavity 13. Then, the battery cell 5 can be picked up and placed into the cavity 13 by an automated method such as a suction cup or a gripper. After the automated placement is completed, the vertical carrier plate and the placed battery cell 5 are moved to the coating process chamber of the coating equipment. At this time, due to the loss of the external force of the electromagnet 4, the first connecting rod 21 returns to the initial locked position under the action of the spring 33, and the stop pin 24 moves back to the top of the cavity 13, which can prevent the battery cell 5 from falling out of the cavity 13 of the vertical carrier plate.

[0049] The vertical carrier plate designed in Example 1, which can fix the battery cells, can improve the start-up efficiency of the hot wire coating equipment and reduce the rework rate and breakage rate of the battery cell hot wire coating process. Meanwhile, the vertical carrier plate designed in Example 1 has a simple opening method for its blocking structure 2, thus avoiding the problem of complex opening methods in existing vertical carrier plates. Because the opening method of the blocking structure 2 in Example 1 is simple, it can save opening time compared to existing blocking structures, thereby effectively improving the efficiency of loading battery cells into the cavity and increasing production efficiency.

[0050] The above-described preferred embodiments of this utility model are for illustrative purposes only and are not intended to limit the scope of this utility model. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
