Description

Technical Field

[0001] This utility model relates to the field of sheet material conveying technology, specifically to a feeding and conveying device for a battery cell testing mechanism. Background Technology

[0002] After the solar cells are manufactured, they need to be classified into different grades according to their own power generation efficiency, so that solar cells can be classified into different price ranges according to different grades, which facilitates subsequent classification, packaging and sales.

[0003] Due to the limitations of existing power generation testing devices, in order to ensure the accuracy of testing and the convenience of subsequent classification, only one solar cell is usually tested at a time. After the upstream conveying equipment transports the solar cell to the entrance, it can be gripped by a robotic arm and moved into the power generation testing device for testing.

[0004] For example, the utility model patent with announcement number CN209327541U discloses a battery cell efficiency testing device. This patent uses a conveying device with a belt conveyor mechanism as the main component to transport the battery cells one by one, move them to the entrance of the testing mechanism, and have them picked up and fed by suction cups.

[0005] Since the solar cells need to be removed from the tray by a robotic arm with suction cups when they are transported to the feeding conveyor, there will be a certain gap between two adjacent solar cells. Under continuous testing conditions, the supply of solar cells may not be able to meet the continuous operation of the testing mechanism, causing the testing mechanism to wait for the solar cells to move to the entrance, which affects the efficiency of the testing. In this regard, this application provides a feeding conveyor for a solar cell testing mechanism to solve the above problems. Utility Model Content

[0006] Based on the above description, this utility model provides a feeding and conveying device for a battery cell testing mechanism to solve the problem that in the existing battery cell feeding and conveying process, there is a gap between two adjacent battery cells, which requires the continuously operating testing mechanism to wait and affects the actual testing efficiency.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A feeding and conveying device for a battery cell testing mechanism includes a frame, wherein the frame is provided with two transfer mechanisms for adsorbing and transferring battery cells, and two loading modules for placing battery cells.

[0008] It also includes a conveying assembly for conveying battery cells, wherein the transfer mechanism is located between the top of the loading module and the conveying assembly;

[0009] The conveying assembly includes a frame housed within a machine frame, a power source mounted on the frame, and two belt drive modules that jointly convey the battery cells. The two belt drive modules are coaxially driven by the same power source.

[0010] Two sensing modules for sensing the battery cells are provided between the two belt drive modules on opposite sides.

[0011] The above technical solution enables two transfer mechanisms to adsorb the battery cells placed in the two loading modules and transfer them to the same conveying component. The two belt drive modules driven coaxially can not only meet the normal transport of the battery cells, but also create a through space between them. The two sensing modules can use this space to sense the battery cells and determine whether the battery cells on the belt drive module are in a fully loaded state.

[0012] Based on the above technical solution, the present invention can be further improved as follows.

[0013] Furthermore, the frame includes two support frames disposed within the machine frame, and two supporting steels are disposed between the outer sides of the two support frames, with the two supporting steels arranged in parallel.

[0014] The above technical solution enables the support frame and support steel to provide installation space for the belt drive module.

[0015] Furthermore, the belt drive module includes a first pulley and a second pulley rotatably connected to the outside of the support steel, and the second pulley is rotatably connected to the outside of the corresponding support steel via a rotating shaft;

[0016] A conveyor belt is connected between the outer side of the first pulley and the corresponding second pulley. The two conveyor belts are located on opposite sides of the two supporting steels. The diameter of the first pulley is larger than the diameter of the second pulley.

[0017] The above technical solution enables the two conveyor belts to be driven normally for transmission and conveying operations.

[0018] Furthermore, the power source includes a dual-axis motor located between two opposing sides of the supporting steel, and the supporting steel has a support hole through which the output shaft of the dual-axis motor passes.

[0019] The output shaft of the dual-axis motor is rotatably connected to the inner side of the corresponding support hole via a bearing, and the two output shafts of the dual-axis motor are respectively fixed to two first pulleys.

[0020] Through the above technical solution, the dual-axis motor can drive the two first pulleys to rotate synchronously, achieving the effect of coaxial synchronous operation.

[0021] Furthermore, the sensing module includes a U-shaped frame disposed between two supporting steels, with mounting holes provided on the U-shaped frame, and a proximity sensor disposed inside the mounting holes.

[0022] The above technical solution enables the proximity sensor to be installed between two supporting steel beams to operate.

[0023] Furthermore, the sensing surface of the proximity sensor is arranged parallel to the top of the conveyor belt, and the distance between the sensing surface of the proximity sensor and the top of the conveyor belt is L, 2mm. <L<8mm。

[0024] The above technical solution enables the sensing surface of the proximity sensor to effectively sense the bottom of the battery cell.

[0025] Furthermore, the transfer mechanism includes a linear transmission module located inside the frame, and the linear transmission module is provided with a displacement plate that can be driven by it to perform linear motion.

[0026] The displacement plate is equipped with two pneumatic adsorption components that can move up and down.

[0027] Through the above technical solution, the linear transmission module can drive the displacement plate to move closer to or away from the conveyor belt, and the battery cells can be adsorbed and transferred through the pneumatic adsorption component.

[0028] Furthermore, the two linear drive modules correspond to the positions of the two load modules respectively, and the displacement plate can be moved between the tops of the two conveyor belts.

[0029] The above technical solution enables the pneumatic adsorption component to place the battery cells between the tops of the two conveyor belts.

[0030] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0031] 1. The dual-station, single-path feeding and conveying method ensures that the battery cells on the conveyor belt are always fully loaded, reducing the gap between two adjacent battery cells and eliminating the need to increase the number of conveyor belts. This allows the downstream testing mechanism to operate without waiting for battery cell supply, thus meeting the needs of continuous testing and improving the continuity and efficiency of testing.

[0032] 2. By setting up proximity sensors, it can be perfectly adapted to the sensing work of battery cells, enabling it to intuitively and quickly sense whether there are battery cells in the target space. In this way, a continuous feeding effect can be achieved through simple structural cooperation, which facilitates maintenance work by operators. Attached Figure Description

[0042] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0044] Example: Reference Figure 1 and Figure 2A feeding and conveying device for a battery cell testing mechanism includes a frame 1, with two transfer mechanisms 2 for adsorbing and transferring battery cells and two loading modules 3 for placing battery cells inside the frame 1; it also includes a conveying assembly 4 for conveying battery cells, with the transfer mechanisms 2 located between the loading modules 3 and the top of the conveying assembly 4; the conveying assembly 4 includes a frame body located inside the frame 1, with a power source on the frame body, and two belt drive modules that jointly convey battery cells, the two belt drive modules being coaxially driven by the same power source; two sensing modules for sensing battery cells are provided between opposite sides of the two belt drive modules.

[0045] It should be noted that both the transfer mechanism 2 and the conveying component 4 are electrically connected to the controller and the power supply. The controller can be a computer or other existing known control device, which can be implemented through simple programming by those skilled in the art. The electrical connection technology is a known technology, so it will not be described in detail.

[0046] refer to Figure 3 The frame includes two support frames 41 located inside the frame 1. Two support steels 42 are provided between the outer sides of the two support frames 41. The two support steels 42 are arranged in parallel so that the support frames 41 and the support steels 42 can provide installation space for the belt drive module.

[0047] refer to Figure 3 and Figure 5 The belt drive module includes a first pulley 43 and a second pulley 44 rotatably connected to the outside of the support steel 42. The second pulley 44 is rotatably connected to the outside of the corresponding support steel 42 via a rotating shaft, so that the second pulley 44 can rotate stably under the support and rotation of the rotating shaft. A conveyor belt 45 is connected between the outside of the first pulley 43 and the corresponding outside of the second pulley 44. The two conveyor belts 45 are located on opposite sides of the two support steels 42. The diameter of the first pulley 43 is larger than the diameter of the second pulley 44. Through the difference in diameter between the first pulley 43 and the second pulley 44, the conveyor belts 45 can have a certain angle, making them easier to tension, so that the two conveyor belts 45 can be driven normally for transmission and conveying.

[0048] refer to Figure 3 and Figure 4, The power source includes a double-shaft motor 46 disposed between opposite sides of two support steels 42. Support holes are provided on the support steels 42 for the output shafts of the double-shaft motor 46 to pass through. The output shafts of the double-shaft motor 46 are rotatably connected to the inner sides of the corresponding support holes through bearings, enabling the output shafts of the double-shaft motor 46 to be supported and rotated stably through the bearings; the two output shafts of the double-shaft motor 46 are respectively fixed to two first belt pulleys 43. The double-shaft motor 46 can drive the two first belt pulleys 43 to rotate synchronously, and then can drive two second belt pulleys 44 to rotate synchronously under the driving effect of the conveyor belt 45, achieving the effect of coaxial synchronous operation of the conveyor belt 45.

[0049] During use, the double-shaft motor 46 drives the two first belt pulleys 43 to move synchronously. Under the driving effect of the conveyor belt 45 and the tensioning effect of the second belt pulley 44, the two conveyor belts 45 can achieve the effect of synchronous operation, and then the solar cells placed between the tops of the two conveyor belts 45 can be smoothly conveyed.

[0050] Reference Figure 3 and Figure 5 , The sensing module includes a U-shaped frame 47 disposed between two support steels 42. Mounting holes are provided on the U-shaped frame 47, and a proximity sensor 48 is provided inside the mounting holes, enabling the proximity sensor 48 to be disposed between the two support steels 42 for operation.

[0051] Reference Figure 3 and Figure 5 , The sensing surface of the proximity sensor 48 is arranged parallel to the top of the conveyor belt 45, and the distance between the sensing surface of the proximity sensor 48 and the top of the conveyor belt 45 is L, where 2mm < L < 8mm, enabling the sensing surface of the proximity sensor 48 to effectively sense the bottom of the solar cell; specifically, the solar cell contains metal, and electromagnetic induction can be performed on the metal target, thereby achieving the effect of proximity sensing.

[0052] During use, the two proximity sensors 48 can divide the space between the opposite sides of the two support steels 42 into two sensing spaces, enabling them to respectively meet the placement requirements of the solar cells transferred by the two transfer mechanisms 2; when one of the sensing spaces is in an empty state, the corresponding transfer mechanism 2 places the adsorbed solar cell again, enabling the two sensing spaces to always be in a full state, and then enabling the solar cells conveyed on the conveyor belt 45 to be continuously transported without interruption.

[0053] Reference Figure 2The transfer mechanism 2 includes a linear drive module 21 located inside the frame 1. The linear drive module 21 is equipped with a displacement plate 22 that can be driven to move linearly. The linear drive module 21 can drive the displacement plate 22 to move closer to or away from the conveyor belt 45. The displacement plate 22 is equipped with two pneumatic adsorption components 23 that can move up and down. The pneumatic adsorption components 23 that can move up and down can adsorb and transfer the battery cells and place them on the conveyor belt 45.

[0054] It should be noted that the linear drive module 21 can be a screw drive module, which can meet the requirements of linear reciprocating conveying, or it can be other linear drive structures that can meet the same requirements. All of these are existing technologies, so they will not be described in detail.

[0055] It should also be noted that the pneumatic adsorption component 23 includes a steel profile on the displacement plate 22, a cylinder and an air pump on the steel profile, and a suction cup assembly on the piston end of the cylinder. The suction cup assembly consists of a support and several suction cups on the support. The suction cups are connected to the air pump, so that the air pump can achieve the effect of negative pressure adsorption through the suction cups, and the cylinder can drive the suction cup assembly to achieve the effect of up and down movement.

[0056] refer to Figure 2 The two linear drive modules 21 correspond to the positions of the two load modules 3 respectively. The displacement plate 22 can be moved between the tops of the two conveyor belts 45, so that the pneumatic adsorption component 23 can place the battery cell between the tops of the two conveyor belts 45.

[0057] It should be noted that the battery cells need to be separated by pads when placed. The loading module 3 includes a placement tray for placing both battery cells and pads, and a collection tray for placing the pads.

[0058] In use, the linear drive module 21 drives the corresponding displacement plate 22 to move linearly, causing the corresponding pneumatic adsorption component 23 to move above the placement tray. The pneumatic adsorption component 23 moves down to adsorb the pads covering the battery cells. The displacement plate 22 continues to move, causing another pneumatic adsorption component 23 to move above the placement tray to adsorb the battery cells. At this time, the pneumatic adsorption component 23 with the pads adsorbed moves above the collection tray. The pneumatic adsorption component 23 moves down and releases adsorption, causing the pads to fall into the collection tray. The displacement plate 22 moves to the side closer to the conveyor belt 45, causing the pneumatic adsorption component 23 with the battery cells adsorbed to move between the tops of the two conveyor belts 45. The pneumatic adsorption component 23 moves down and places the battery cells between the tops of the two conveyor belts 45, completing the transfer and loading work.

[0059] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
