Description

Technical Field

[0001] This invention relates to the field of photovoltaic solar cell processing technology, specifically to a photovoltaic laser processing device. Background Technology

[0002] Existing photovoltaic laser processing equipment typically only has one NG box for storing substandard silicon material. A loading / unloading robot usually picks up the substandard silicon material and places it into the NG box. However, silicon material after laser processing is often not tested, or even if it is tested, there is no NG box for storing substandard silicon material. Alternatively, if an NG box is provided for storing substandard silicon material, a separate robot needs to be designed to pick up the substandard silicon material and place it into the NG box. Since the existing equipment layout is already very compact, there is no space to accommodate the NG box and the robot, so it often needs to be externally mounted on the outside of the equipment.

[0003] However, with the continuous development of the photovoltaic solar cell industry, the functions of photovoltaic solar cell processing equipment are becoming more and more powerful. They already occupy a lot of space, and external equipment will further increase the area occupied by laser processing equipment, posing a greater challenge to the factory's plant area.

[0004] Therefore, it is necessary to make reasonable arrangements for the internal components of photovoltaic laser processing equipment, improve the original structure and space of the equipment, achieve the newly added functional effects without increasing the volume of the processing equipment, save the floor space, and improve the utilization rate of the factory. Summary of the Invention

[0005] In view of this, the main objective of the present invention is to provide a photovoltaic laser processing device with a reasonable internal component layout.

[0010] Furthermore, in some embodiments, one of the rotating component and the lifting component is a driving component and the other is a follower component.

[0011] As an improvement, in some embodiments, the rotating component is a driving component, the lifting component is a follower component, the lifting component includes a rotating lifting platform and a cylindrical body sleeved around the rotating lifting platform, the rotating lifting platform is fixedly connected to the output shaft of the rotating cylinder, the conveying platform is fixedly installed on the rotating lifting platform, the cylindrical body is provided with a spiral groove, and a follower pulley is fixedly provided on the rotating cylinder, the pulley matching the spiral groove.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] During the processing of photovoltaic silicon materials, some silicon inevitably becomes defective due to errors and disturbances. Therefore, it is necessary to separate defective products from the qualified ones and place them separately. Existing photovoltaic laser processing equipment has a set of inspection devices and NG boxes, generally located before the processing station for incoming material inspection. Some high-requirement laser processing equipment is equipped with two sets of inspection devices and NG boxes, with another set located after the processing station for inspecting the quality of the processed material. However, because photovoltaic laser processing equipment models are often quite mature and the equipment layout is already very compact, adding new structures often requires external mounting or increasing the equipment's footprint, and necessitates the design of a separate robotic arm to pick up defective silicon and place it into the NG box.

[0026] To address at least one of the above problems, the present invention provides a photovoltaic laser processing device, for details please refer to... Figure 1 The system includes a base 1, a loading conveyor 2 and a unloading conveyor 3 arranged parallel to the base 1, and a loading / unloading robot 4, a processing turntable 5, a laser module 6, and a first NG box 7 fixedly mounted on the base 1. The loading / unloading robot 4 and the laser module 6 are configured on both sides of their respective processing turntables 5. The loading / unloading robot 4 and the first NG box 7 are configured between the loading conveyor 2 and the unloading conveyor 3. The processing turntable 5 and the first NG box 7 are located on both sides of the loading / unloading robot 4. It also includes a first detection device 8 and a control unit. The first detection device 8 is configured on the loading conveyor 2 and is signal-connected to the control unit for material detection.

[0027] When the first inspection device 8 determines that the incoming material is qualified, the control unit controls the loading / unloading robot 4 to pick up the silicon material to be processed from the loading conveyor 2, rotate it 90 degrees along the first direction, and then transfer the silicon material to the processing turntable 5. After the processing turntable 5 rotates 180 degrees, the loading / unloading robot 4 picks up the processed silicon material from the processing turntable 5 and transfers it to the unloading conveyor 3. When the first inspection device 8 determines that the incoming material is unqualified, after receiving the defect signal sent by the first inspection device 8, the control unit controls the loading / unloading robot 4 to rotate it 90 degrees along the second direction and then transfer the defective material into the first NG box 7.

[0028] It also includes a second NG box 10 and a second detection device 9 disposed in front of the unloading conveyor 3. Both the unloading conveyor 3 and the loading conveyor 2 include multiple conveying units connected in sequence. One of the conveying units of the unloading conveyor 3 is configured as a rotary conveyor unit 11. The rotary conveyor unit 11 is located after the second detection device 9. The rotary conveyor unit 11 and the second detection device 9 are respectively signal connected to the control unit. The second NG box 10 is configured to be located between the loading conveyor 2 and the unloading conveyor 3 and close to one side of the unloading conveyor 3. The second NG box 10 is on one side of the rotary conveyor unit 11 and matches the position of the rotary conveyor unit 11 after rotation.

[0029] When the second detection device 9 detects the laser-processed incoming material on the unloading conveyor 3 and determines it to be qualified, the control unit receives the signal from the second detection device 9 and controls the rotary conveyor unit 11 to convey the material in the original conveying direction, completing the unloading action. When the second detection device 9 determines that the incoming material is unqualified, the control unit receives the defect signal sent by the second detection device 9 and controls the rotary conveyor unit 11 to rotate 90 degrees to transfer the defective material into the second NG box 10.

[0030] like Figure 2 As shown, the rotary conveying unit 11 includes a conveying platform 111 and a rotating assembly 112. The conveying platform 111 is mounted on the rotating assembly 112 and rotates in the same direction as the rotating assembly 112. The rotating assembly 112 is signal-connected to the control unit. When the second detection device 9 determines that the incoming material is defective, the control unit controls the rotating assembly 112 to rotate 90 degrees, and the conveying platform 111 continues to convey forward. The defective material falls off the conveying platform 111 and into the second NG box 10, completing the transfer of defective products.

[0031] To achieve better transfer results, as an improvement, the plane where the second NG box 10 is located is configured to be lower than the plane where the conveying platform 111 is located.

[0032] In reality, to ensure the accuracy and stability of the conveying process, the conveying units are often arranged very closely, with a gap of less than 1 cm between them. Therefore, directly driving the rotary conveying unit 11 to rotate would cause interference between the rotary conveying unit 11 and the next conveying unit. In other words, if it rotates directly, the corner of the rotary conveying unit 11 will bump into the next conveying unit.

[0033] To solve the above problems, such as Figure 3As shown, as another improvement, the rotary conveying unit 11 also includes a lifting assembly. The conveying platform 111 is configured on the lifting assembly, and the conveying platform 111 changes its conveying plane by moving up and down with the lifting assembly. When the rotary conveying unit 11 receives a signal from the control unit, it raises the conveying platform 111 while rotating. The raised conveying platform 111 avoids interference with the next conveying unit. After the rotary assembly 112 rotates 90 degrees, the conveying platform 111 continues to convey forward. Defective materials fall off the conveying platform 111 and into the second NG box 10, completing the transfer of defective products.

[0034] As an embodiment of the present invention, the rotating component 112 and the lifting component can be independent of each other or integrated. When the rotating component 112 and the lifting component are driven independently, no specific limitation is made here, as long as lifting can be achieved simultaneously during rotation and interference is avoided; when the rotating component 112 and the lifting component are integrated and share a power source, one of them is a driving component and the other is a follower component, and the follower component moves along with the driving component.

[0035] Specific

[0036] In one embodiment, the rotating component 112 is a driving component, specifically a rotary cylinder. The lifting component is a follower component. The lifting component includes a rotary lifting platform 116 and a cylindrical body 113 sleeved around the rotary lifting platform 116. The rotary lifting platform 116 is fixedly connected to the output shaft of the rotary cylinder, and the conveying platform 111 is fixedly mounted on the rotary lifting platform 116. A spiral groove 114 is provided on the cylindrical body 113, and a follower pulley 115 is fixedly provided on the rotary lifting platform 116. The pulley matches the spiral groove 114, and the rotation arc of the spiral groove 114 is 90 degrees.

[0037] When the rotating component 112, i.e., the rotating cylinder, receives a signal from the control unit, it controls the rotating cylinder to drive the rotating lifting platform 116 to rotate. During the rotation of the rotating lifting platform 116, it is constrained by the spiral chute 114, and the follower pulley 115 drives the rotating lifting platform 116 to rise synchronously. When the rotating lifting platform 116 rotates 90 degrees, the conveying platform 111 mounted on it also rotates 90 degrees. After reaching the designated position, the conveying platform 111 continues to convey, and the defective silicon material falls into the second NG box 10. Subsequently, the control unit controls the rotating cylinder to rotate in the opposite direction, and the rotating lifting platform 116 returns to its original position.

[0038] In another embodiment, the lifting assembly is a driving component, specifically a lifting cylinder. The rotating assembly 112 is a follower component, comprising a rotating lifting platform 116 and a cylindrical body 113 sleeved around the rotating lifting platform 116. The rotating lifting platform 116 is connected to the output shaft of the lifting cylinder, and the rotating lifting platform 116 is axially rotatable along the output shaft of the lifting cylinder. The conveying platform 111 is fixedly mounted on the rotating lifting platform 116. A spiral groove 114 is provided on the cylindrical body 113, and a follower pulley 115 is fixedly provided on the rotating lifting platform 116. The pulley matches the spiral groove 114, and the rotation arc of the spiral groove 114 is 90 degrees.

[0039] When the lifting assembly, i.e., the lifting cylinder, receives a signal from the control unit, it controls the rotary cylinder to drive the rotary lifting platform 116 to lift. During the lifting process, the rotary lifting platform 116 is constrained by the spiral chute 114, and the follower pulley 115 drives the rotary lifting platform 116 to rotate synchronously. When the rotary lifting platform 116 rotates 90 degrees, the conveying platform 111 mounted on it also rotates 90 degrees. After reaching the designated position, the conveying platform 111 continues to convey, and the defective silicon material falls into the second NG box 10. Subsequently, the control unit controls the rotary cylinder to rotate in the opposite direction, and the rotary lifting platform 116 returns to its original position.

[0040] The photovoltaic laser processing equipment of the present invention configures the NG box between the feeding and unloading conveying devices, eliminating the need for external space occupation. By cleverly designing the original conveying unit as a rotatable conveying unit, the equipment can complete the action of collecting defective products after laser processing into the NG box without the need for additional mechanisms. This can significantly save costs and space, improve the space utilization of the equipment, and make the positional layout of the components of the entire photovoltaic laser processing equipment more scientific and the overall layout more compact and reasonable.
