Description
Technical Field
[0001] The present invention relates to the technical field of battery manufacturing, and particularly to a string placing machine. Background Art
[0002] With the continuous development of society, energy consumption is increasing. Non-renewable energy sources such as coal and oil are decreasing day by day. At the same time, the consumption of traditional energy sources will cause obvious environmental pollution. Problems such as energy crisis and environmental pollution are becoming increasingly prominent, and even have begun to restrict economic development.
[0003] Solar energy is an inexhaustible and renewable energy source. If electricity is obtained from solar energy, it will benefit mankind. People achieve this through the photovoltaic effect by manufacturing solar cells for photoelectric conversion. With the progress of technology and the development of the photovoltaic industry, solar panels have begun to be mass-produced. In the production process, first, a number of relatively small unit battery wafers are arranged into battery strings, and then several battery strings are arranged in columns for welding to form a component. Then, the battery string component is placed on a glass plate for subsequent process production. Currently, in the production process of photovoltaic silicon crystal battery wafers, each process is basically operated by relatively independent equipment. For example, after the string welding machine processes to form a battery string, it is also necessary to cut the lead wires and then place the strings on the glass, etc. The separate operation of each process makes the overall structure of the production line relatively complex, the production efficiency is low, and usually the equipment cost is relatively high.

[0038] The present invention integrates the wire cutting and string placing processes onto one device, enabling one device to complete two processes simultaneously, improving the utilization rate of the device, simplifying the entire battery production line equipment, thereby greatly improving the processing efficiency and reducing the production cost of the battery, which has a positive effect on the development of the photovoltaic industry. The following is a detailed introduction to the present invention with specific embodiments: As Figure 1 、 Figure 2 shown, the present invention provides a string placing machine, including a frame 1, and provided on the frame 1 are: a battery conveying mechanism 7 for conveying the battery string to the grasping station;
[0039] a glass conveying mechanism for transporting the glass;
[0040] a grasping mechanism 4 for grasping the battery string at the grasping station, moving the battery string to the cutting station, and placing the string on the glass;
[0041] a cutting mechanism 5 for cutting the end leads of the battery string at the cutting station.
[0042] Specifically, the glass conveying mechanism includes:
[0043] a feeding conveying mechanism for transporting the glass to the loading station;
[0044] a discharging conveying mechanism for transporting the glass after string placing out.
[0045] A material transfer mechanism is used to move the glass at the loading station to the stringing station and place it on the discharging conveyor mechanism. The battery strings are strung on the glass at the stringing station.
[0046] Specifically, the battery conveyor mechanism 7 includes conveyor belts. In this embodiment, two battery conveyor mechanisms 7 are provided and arranged in parallel. The battery strings completed by the string welding machine are transported to the stringing machine through the battery conveyor mechanism 7, specifically to the loading station. The feeding conveyor mechanism includes a feeding conveyor belt 21 and rollers 22. In the conveying direction, the feeding conveyor belt 21 is provided in multiple sections, and a plurality of rollers 22 are provided between adjacent sections. The rollers 22 are perpendicular to the feeding conveyor belt 21, and the positions where the rollers 22 are located form the loading station, and there is one or more loading stations. In this embodiment, two loading stations are provided to cooperate with the operation of the string welding machine. Preferably, each section of the feeding conveyor belt 21 includes two conveyor belts arranged in parallel, and the length of the roller 22 is the same as the distance between the two conveyor belts. A plurality of rollers 22 are arranged in parallel at equal intervals. Further, the rollers 22 are unpowered rollers 22, and the width of the loading station, that is, the distance between adjacent sections of the adjacent feeding conveyor belts 21, is less than the width of the glass, so as to ensure that the glass located at the loading station can keep in contact with the conveyor belt and ensure that the glass can move under the drive of the conveyor belt.
[0047] The material transfer mechanisms are arranged in one-to-one correspondence with the loading stations. Each material transfer mechanism corresponds to one loading station, that is, each material transfer mechanism is used to move the glass on one loading station and move the glass to the stringing station. The material transfer mechanism includes a support rod 31 and a displacement driving mechanism. The support rod 31 is perpendicular to the feeding conveyor belt 21, and the support rod 31 is drivingly connected to the displacement driving mechanism. Further, the displacement driving mechanism includes a translation driving component and a lifting driving component. The displacement driving mechanism can drive the support rod 31 to move in the horizontal direction and the vertical direction. Preferably, both the translation driving component and the lifting driving component can be composed of components such as motors, cylinders, and hydraulic cylinders.
[0048] Specifically, driven by the displacement driving mechanism, one end of the support rod 31 can extend to the lower side of the loading station (that is, the lower side or the side part of the roller 22) so that a part of the support rod 31 is located under the glass on the loading station. Then, the support rod 31 moves upward to lift the glass from the loading station. Then, the support rod 31 moves horizontally to move the glass from the loading station to the grasping station for the grasping mechanism 4 to grasp and perform the next process operation.
[0049] The rack 1 includes a gantry 11 which is arranged parallel to the feeding conveyor belt 21. A slide rail is provided on the gantry 11, and the grasping mechanism 4 is slidably arranged on the slide rail. The grasping mechanism 4 includes a grasping driving mechanism and a suction cup assembly 41. The grasping driving mechanism is drivingly connected to the suction cup assembly 41. The grasping driving mechanism includes a vertical driving component and a rotary driving component. The suction cup assembly 41 includes a plurality of suction cups. The grasping driving mechanism is used to drive the suction cup assembly 41 to move vertically and rotate horizontally. Similarly, both the vertical driving component and the rotary driving component can be composed of components such as motors, cylinders, and hydraulic cylinders. The suction cup assembly 41 includes a suction cup rod which is connected to the grasping driving mechanism. A plurality of suction cups are arranged along the extending direction of the suction cup rod. The plurality of suction cups are arranged according to the length of the battery string. The plurality of suction cups grasp the battery string simultaneously, improving the reliability of grasping. Further, the middle position of the suction cup rod is connected to the grasping driving mechanism. The suction cup driving mechanism can drive the suction cup rod to rotate horizontally by 90°, so that the battery string moves to the shearing station.
[0050] Specifically, two grasping mechanisms 4 are provided on the gantry 11. The two grasping mechanisms 4 can move independently. Each grasping mechanism 4 corresponds to a battery conveying mechanism 7 and grasps the battery string on one battery conveying mechanism 7. After each grasping mechanism 4 grasps the battery string, it independently completes the wire cutting and string placing actions.
[0051] The shearing mechanism 5 is arranged close to the gantry 11. The shearing mechanism 5 includes a cutter assembly. At the shearing station, the end lead of the battery string extends into the cutter assembly. The cutter assembly includes a cutter mounting rack and a cutter. The cutter is mounted on the cutter mounting rack and its movement is controlled by a cutter control mechanism to realize the shearing of the end lead of the battery string.
[0052] The shearing mechanism 5 further includes a positioning assembly. The positioning assembly includes a backlight component and a visual positioning component. The backlight component and the visual positioning component are used to position the battery string located at the shearing station.
[0053] Preferably, after the grasping mechanism 4 grasps the battery string, it rotates horizontally by 90° to align the end of the battery string with the shearing mechanism 5. Then, the grasping mechanism 4 translates along the gantry 11 to extend the lead at the end of the battery string into the shearing mechanism 5 to complete the wire cutting operation. Then, the grasping mechanism 4 places the battery string after the wire cutting operation on the glass.
[0054] The discharging conveyor mechanism includes a discharging conveyor belt 61. The discharging conveyor belt 61 corresponds to the supporting rod 31 one by one and is arranged parallel to each other. The discharging conveyor belt 61 is used to carry the glass at the grasping station and convey the glass after the string placing is completed to the next process. Preferably, the discharging conveyor belt 61 is arranged parallel to the supporting rod 31, and one discharging conveyor belt 61 is arranged corresponding to each supporting rod 31.
[0055] Preferably, after moving the glass to the grasping station, the supporting rod 31 can lower its height to place the glass on the discharging conveyor belt 61, that is, in the wire cutting and string arranging processes, the glass is located on the discharging conveyor belt 61, and with the string arranging operation, the glass can be gradually driven backward by the discharging conveyor belt 61. Alternatively, in other embodiments, in the wire cutting and string arranging processes, the glass can also be always placed on the supporting rod 31, and after the string arranging is completed, the supporting rod 31 moves downward to place the glass on the discharging conveyor belt 61 and is sent out by the discharging conveyor belt 61.
[0056] The present invention further provides a battery production line, including the above-mentioned string arranging machine. The string arranging machine is located at the rear side of the string welding machine. After the battery string is welded by the string welding machine, the battery string is conveyed into the string arranging machine, and at the same time, the glass is also conveyed into the string arranging machine. After the battery string completes the wire cutting operation, string arranging is performed on the glass, and then it is sent out by the discharging conveying mechanism. Preferably, in this embodiment, the string arranging machine is provided with two loading stations, and the operations of placing battery strings on two glasses can be completed simultaneously, greatly improving the battery production efficiency.
[0057] The above specifically illustrates and describes the exemplary embodiments of the present disclosure. It should be understood that the present disclosure is not limited to the detailed structures, setting manners or implementation methods described herein; on the contrary, the present disclosure is intended to cover various modifications and equivalent settings included within the spirit and scope of the appended claims.
