Description

Technical Field

[0001] This application belongs to the field of battery cell technology, specifically relating to a mesh belt correction device. Background Technology

[0002] In the production process of solar cells, screen printing is a key step. It requires the uniform application of a photosensitive adhesive material onto the surface of the coated solar cell. After coating, the solar cell needs to be baked to evaporate the moisture and volatile additives in the photosensitive adhesive material, thereby obtaining a smooth and dried coated solar cell. The drying oven, as the baking device for the solar cell, usually needs to be equipped with a mesh belt as a conveyor to carry the solar cell so that the solar cell is dried while being transported.

[0003] However, during the drying cycle, the mesh belt rubs against the conveyor rollers, causing the mesh belt to shift position on the conveyor rollers, or even run to the edge of the machine and rub against the metal edge of the machine, which can damage the battery cells it carries, thus affecting production efficiency and product quality. Utility Model Content

[0004] This application provides a conveyor belt correction device that can correct the deviation of the conveyor belt transported on the conveyor rollers, thereby improving the production efficiency and quality of the products.

[0005] To address the aforementioned technical problems, this application provides a conveyor belt alignment device for correcting the alignment of a conveyor belt transported on a conveyor roller, comprising:

[0006] A sensing unit, located near the conveyor roller, is used to detect the tension of the conveying mesh belt;

[0007] A lifting unit is located at the bottom of the conveyor roller. The conveyor roller has transmission bearings at opposite ends. The lifting unit is connected to a connecting piece sleeved on the transmission bearing. The lifting unit is used to adjust the height of both sides of the conveyor roller according to the detected tension of the mesh belt, so as to correct the mesh belt to a preset position.

[0008] As a further improvement of this application, the two sides of the conveying roller are provided with support plates extending in the height direction, and the two support plates are provided with guide grooves on the side that is close to each other, so as to allow the connector to move in the height direction and engage the connector between the two support plates.

[0011] As a further improvement of this application, the lifting unit includes a fixed block disposed between the two support plates, a support rod passing through the fixed block along the height direction and threadedly connected to the fixed block, and a top block connected to the support rod and the second connecting part respectively;

[0012] The fixing block is positioned away from the conveying roller so that the height of the conveying roller can be adjusted by adjusting the degree of screw connection between the support rod and the fixing block.

[0013] As a further improvement of this application, a fixing nut is provided at the position where the fixing block and the support rod are screwed together.

[0014] As a further improvement of this application, an adjustment block is provided on the side of the support rod away from the conveying roller;

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0026] In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified. All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the figures). If the specific posture changes, the directional indication will also change accordingly. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0027] To make the description of this disclosure more detailed and complete, illustrative descriptions of the implementation methods and specific embodiments of this application are provided below; however, this is not the only form of implementing or utilizing the specific embodiments of this application. The implementation methods cover the features of multiple specific embodiments and the method steps and their order for constructing and operating these specific embodiments. However, other specific embodiments may also be used to achieve the same or equivalent functions and step sequences.

[0028] In the production process of solar cells, screen printing is a key step. It requires the uniform application of a photosensitive adhesive material onto the surface of the coated solar cell. After coating, the solar cell needs to be baked to evaporate the moisture and volatile additives in the photosensitive adhesive material, thereby obtaining a smooth and dried coated solar cell. The drying oven, as the baking device for the solar cell, usually needs to be equipped with a mesh belt as a conveyor to carry the solar cell so that the solar cell is dried while being transported.

[0029] Since the screen-printed solar cells are fed into the drying oven by a conveyor belt for high-temperature processing, the conveyor belt needs to be heat-resistant. For example, the conveyor belt can be made of Teflon or other alloy materials. However, during the drying cycle, the conveyor belt will rub against the conveyor rollers, causing the belt to shift on the conveyor rollers or even run to the edge of the machine and rub against the metal edge of the machine. This can damage the solar cells it carries, affecting production efficiency and product quality.

[0030] For the reasons mentioned above, please refer to Figures 1-2 This application provides a conveyor belt deviation correction device that can correct the deviation of the conveyor belt transported on the conveyor rollers, thereby improving product production efficiency and quality. Please refer to... Figure 1 This is a schematic diagram of the structure of the belt correction device provided in the embodiment of this application, and also a side view of the belt correction device. It can be observed that the belt correction device includes a sensing unit 20 and a lifting unit 10.

[0031] As an optional implementation, this application sets the aforementioned sensing unit 20 close to the conveyor roller 2 to detect the tension of the conveyed mesh belt 1, and sets the lifting unit 10 at the bottom of the conveyor roller 2 to adjust the height of both sides of the conveyor roller 2 according to the detected tension of the mesh belt 1, thereby realizing the adjustment of the tension of the mesh belt 1.

[0032] It is understandable that when the tension of the mesh belt 1 changes, the tension distribution of the mesh belt 1 will change. If the mesh belt 1 deviates to one side during operation, appropriately increasing the tension on that side or decreasing the tension on the other side can bring the mesh belt 1 back to the correct position. This application adjusts the tension of the mesh belt 1 by adjusting the height of the conveyor roller 2, thereby correcting the mesh belt 1 to the preset position and preventing damage caused by the mesh belt 1 running to the edge of the machine.

[0033] Typically, transmission bearings 3 are provided on opposite sides of the conveyor roller 2. In this application, a connecting member 11 is fitted onto the transmission bearing 3, and the lifting unit 10 is connected to the connecting member 11. The lifting unit 10 drives the connecting member 11 to move in the height direction, so that the transmission bearing 3 connected to the connecting member 11 and the conveyor roller 2 move in the height direction, thereby realizing the adjustment of the height of the conveyor roller 2. Of course, according to the actual tension of the mesh belt 1, one side of the conveyor roller 2 can be adjusted, or both sides of the conveyor roller 2 can be adjusted simultaneously. Any adjustment method that can correct the mesh belt 1 to the preset position is feasible, and this application does not limit it.

[0034] In an optional embodiment, the present application provides support plates 12 extending along the height direction on both sides of the conveyor roller 2. A guide groove (not shown in the figure) is provided on the side of the two support plates 12 that are close to each other, so as to allow the connector 11 to move in the height direction, thereby snapping the connector 11 between the two support plates 12. Since the connector 11 can move in the height direction, the transmission bearing 3 connected to the connector 11 and the conveyor roller 2 connected to the transmission bearing 3 can also move in the height direction, thereby realizing the position correction of the mesh belt 1.

[0035] Specifically, the connector 11 provided in this application includes a first connecting part 111 that is slidably connected between two support plates 12, and a second connecting part 112 that is connected to the lifting unit 10. Preferably, the transmission bearing 3 is disposed through the first connecting part 111.

[0036] Furthermore, this application also provides guide sliders 113 at both ends of the first connecting part 111 and at the connection position of the guide groove, thereby realizing the sliding connection relationship between the connecting part 11 and the two support plates 12.

[0037] As an optional implementation, the lifting unit 10 provided in this application includes a fixing block 13 disposed between two support plates 12, a support rod 14 passing through the fixing block 13 along the height direction and threadedly connected to the fixing block 13, and a top block 15 connected to the support rod 14 and the second connecting part 112 respectively. Since the fixing block 13 is disposed away from the conveying roller 2 and fixedly disposed between the two support plates 12, and the support rod 14 and the fixing block 13 are threadedly connected, the height of the transmission bearing 3 and the conveying roller 2 can be adjusted by adjusting the degree of threading between the support rod 14 and the fixing block 13.

[0038] Optionally, this application provides an adjustment block 17 on the side of the support rod 14 away from the conveying roller 2. By rotating the adjustment block 17 with a wrench, the degree of screw connection between the support rod 14 and the fixing block 13 can be adjusted. The above is an optional manual adjustment method.

[0039] Of course, a driving component (not shown in the figure) can also be provided on the side of the support rod 14 away from the conveying roller 2, and the driving component can be connected to the support rod 14 for transmission. The support rod 14 can be rotated by the driving component, thereby adjusting the screw connection between the support rod 14 and the fixed block 13. The above is an optional automatic adjustment method. This application does not further limit the specific adjustment method mentioned above. It can be adjusted according to actual needs, or both can be set. When the automatic adjustment fails, the manual method can be used for adjustment. This application will not elaborate on this further.

[0040] Furthermore, to prevent loosening between the fixing block 13 and the support rod 14, this application also provides a fixing nut 16 at the screw connection between the fixing block 13 and the support rod 14. When it is necessary to adjust the height of the conveyor roller 2, the fixing nut 16 is loosened to perform the corresponding operation. When the conveyor belt 1 is transmitting normally, the fixing nut 16 is tightened.

[0041] As an optional implementation, the sensing unit 20 provided in this application includes a tension sensor 21 for detecting the tension of the mesh belt 1, and a main controller that is communicatively connected to the tension sensor 21 for receiving the tension.

[0042] In this embodiment, the main controller receives the tension level, determines whether the tension level exceeds a preset threshold, and provides a prompt when the preset threshold is exceeded to remind the staff to adjust the height of the conveyor roller 2. When a drive unit is provided, the main controller controls the drive unit to adjust the height of the conveyor roller 2.

[0043] For example, the main controller can be set to common controller forms such as MCU (Microcontroller Unit), PFGA (Field Programmable Gate Array), and PLC (Programmable Logic Controller). This application does not impose too many restrictions on the specific configuration of the main controller and tension sensor 21.

[0044] Further, please refer to Figure 2 This is a front view of the conveyor belt correction device provided in this application embodiment. In this application, a support frame 22 for supporting the tension sensor 21 is provided on one of the support plates 12 away from the connector 11. The support frame 22 is set as an L-shaped structure so that the tension sensor 21 is set close to the conveyor roller 2 to detect the tightness of the conveyor belt 1 passing through the conveyor roller 2. At the same time, it is necessary to ensure that the height position of the tension sensor 21 can abut against the bottom of the conveyor belt 1 to avoid affecting the normal transmission of the conveyor belt 1.

[0045] When the main controller determines that the current tension exceeds the threshold, it reminds the staff to adjust the height of the conveyor roller 2, or the main controller controls the drive component to adjust the height of the conveyor roller 2, thereby adjusting the tension of the mesh belt 1 and correcting the mesh belt 1 to the preset position. This application detects the tension of the mesh belt 1 in real time and corrects the position of the mesh belt 1 by adjusting the height of the conveyor roller 2, avoiding contact and friction between the mesh belt 1 and the battery cells during the transmission process, reducing damage to the battery cells during the transmission process, and improving the production efficiency and quality of the product.

[0046] It is understood that the technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above embodiments are merely exemplary implementations used to illustrate the principles of this application; however, this application is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and substance of this application, and these modifications and improvements are also considered to be within the scope of protection of this application.
