Description

Technical Field

[0001] This invention relates to an automated assembly device for photovoltaic modules. Background Technology

[0002] In the production of photovoltaic modules, diodes are usually cut and installed manually. Manual placement is inefficient and there is a certain probability of placing the diodes in the wrong direction, resulting in a certain percentage of scrap and equipment malfunctions. Summary of the Invention

[0003] In order to overcome the problems encountered in the existing production process, the purpose of this invention is to provide an automatic assembly device that can automatically determine and adjust the orientation of components.

[0004] To achieve the above objectives, the present invention provides an automatic photovoltaic module assembly device, comprising a frame, an injection molding part hopper mounted on the frame, an injection molding part linear vibration track connected to the injection molding part hopper, a module diode hopper mounted on the frame, a module diode material linear vibration track connected to the module diode hopper, a robotic arm unit, a pressing station, and a receiving station. The injection molding part linear vibration track has a first detection unit at its end for detecting the orientation of the injection molding part, and the module diode material linear vibration track has a second detection unit at its end for detecting the orientation of the module diode. The robotic arm unit positions the injection molding part and the module diode at the pressing station according to predetermined directions and positions based on the detection results of the first and second detection units. After pressing at the pressing station, the receiving station collects the components.

[0005] Preferably, the first detection unit includes a first lateral sensor and a first longitudinal sensor located in the injection molding part transmission direction. The injection molding part includes a front end and a rear end, and the rear end has a fixing part. When the first lateral sensor and the first longitudinal sensor detect the injection molding part at the same time, the first detection unit determines that the injection molding part is in the forward direction. When the first longitudinal sensor detects the fixing part, the first detection unit determines that the injection molding part is in the reverse direction.

[0006] Preferably, the first detection unit includes a misalignment cylinder disposed perpendicular to the injection molding part conveying direction, a misalignment slider connected to the output end of the misalignment cylinder, and a positioning fixture connected to the misalignment slider. When the injection molding part is conveyed to the positioning fixture, the misalignment cylinder pushes the positioning fixture to a predetermined position according to the judgment result of the first detection unit.

[0007] Preferably, when the injection molded part is in the forward direction, the misalignment cylinder pushes the positioning fixture to the first position according to the judgment result of the first detection unit; when the injection molded part is in the reverse direction, the misalignment cylinder pushes the positioning fixture to the second position according to the judgment result of the first detection unit.

[0008] Preferably, when the injection molded part is in the forward direction, the robotic arm unit grasps the injection molded part from the first position, rotates it forward, and positions it at the press-fitting station. When the injection molded part is in the reverse direction, the robotic arm unit grasps the injection molded part from the first position, rotates it in the reverse direction, and positions it at the press-fitting station.

[0009] Preferably, the second direction detection unit includes a second lateral sensor and a second longitudinal sensor disposed at the end of the module diode. The end of the module diode is provided with a positioning hole. When the second lateral sensor and the second longitudinal sensor detect the module diode at the same time, the second detection unit determines that the module diode is forward. When the second longitudinal sensor detects the positioning hole of the module diode, the second detection unit determines that the module diode is reverse.

[0010] Preferably, when the module diode is in the forward direction, the robotic arm unit grasps the module diode, rotates it in the forward direction, and positions it at the pressing station; when the module diode is in the reverse direction, the robotic arm unit grasps the module diode, rotates it in the reverse direction, and positions it at the pressing station.

[0011] Preferably, the robotic arm unit is a four-axis robotic arm.

[0012] Preferably, the robotic arm unit includes a pneumatic gripper and a vacuum suction cup disposed on the side of the pneumatic gripper, wherein the vacuum suction cup is connected to a vacuum generator via a vacuum valve.

[0013] Preferably, it also includes an inspection station for inspecting the pressing effect.

The end of the injection molding part linear vibration track 3 is equipped with a first detection unit for detecting the orientation of the injection molding part 9, and the end of the modular diode material linear vibration track 5 is equipped with a second detection unit for detecting the orientation of the modular diode 10. The robotic arm unit 6 positions the injection molding part 9 and the modular diode 10 on the pressing station 7 according to predetermined directions and positions based on the detection results of the first and second detection units. The inspection station 18 inspects the pressing effect of the pressing station 7. After pressing is completed at the pressing station 7, the material is collected by the receiving station 8.

[0023] Appendix Figure 2 This is a perspective view of the injection molding part's direct vibration track in the automatic assembly device for photovoltaic modules of the present invention. The first detection unit includes a first lateral sensor 11 and a first longitudinal sensor 12 located in the transmission direction of the injection molding part 9. The injection molding part 9 includes a front end 91 and a rear end 92. The rear end 92 has a fixing part 93. When the first lateral sensor 11 and the first longitudinal sensor 12 detect the injection molding part 9 at the same time, the first detection unit determines that the injection molding part 9 is in the forward direction. When the first longitudinal sensor 12 detects the fixing part 93, the first detection unit determines that the injection molding part 9 is in the reverse direction.

[0024] The first detection unit includes a material-shifting cylinder 13 disposed perpendicular to the conveying direction of the injection molded part 9, a material-shifting slider 14 connected to the output end of the material-shifting cylinder 13, and a positioning fixture 15 connected to the material-shifting slider 14. When the injection molded part 9 is conveyed to the positioning fixture 15, the material-shifting cylinder 13 pushes the positioning fixture 15 to a predetermined position according to the judgment result of the first detection unit. When the injection molded part 9 is in the forward direction, the material-shifting cylinder 13 pushes the positioning fixture 15 to a first position according to the judgment result of the first detection unit. When the injection molded part 9 is in the reverse direction, the material-shifting cylinder 13 pushes the positioning fixture 15 to a second position according to the judgment result of the first detection unit. When the injection molded part 9 is in the forward direction, the robotic arm unit 6 grasps the injection molded part 9 from the first position, rotates it 90 degrees forward, and positions it on the press-fitting station 7. When the injection molded part 9 is in the reverse direction, the robotic arm unit 6 grasps the injection molded part 9 from the first position, rotates it 90 degrees backward, and positions it on the press-fitting station 7.

[0025] Appendix Figure 3This is a perspective view of the linear vibration track of the photovoltaic module diode material in the automatic assembly device of the present invention. The second direction detection unit includes a second lateral sensor 16 and a second longitudinal sensor 17 disposed at the end. The end of the module diode 10 is provided with a positioning hole. When the second lateral sensor 16 and the second longitudinal sensor 17 simultaneously detect the module diode 10, the second detection unit determines that the module diode 10 is in the forward direction. When the second longitudinal sensor 17 detects the positioning hole of the module diode 10, the second detection unit determines that the module diode 10 is in the reverse direction. When the module diode 10 is in the forward direction, the robotic arm unit 6 grasps the module diode 10, rotates it 90 degrees in the forward direction, and positions it on the pressing station 7. When the module diode 10 is in the reverse direction, the robotic arm unit 6 grasps the module diode 10, rotates it 90 degrees in the reverse direction, and positions it on the pressing station 7.

[0026] The sensitivity of the first lateral sensor 11, the first longitudinal sensor 12, the second lateral sensor 16, and the second longitudinal sensor 17 has certain requirements. Too low or too high sensitivity will lead to system misjudgment and a certain proportion of defects. Therefore, a medium value needs to be selected after multiple runs.

The robotic arm unit 6 is a four-axis robotic arm loading system, mainly including a pneumatic gripper 61 and a vacuum suction cup 62 disposed on the side of the pneumatic gripper 61. The vacuum suction cup 62 is connected to the vacuum generator 64 through a vacuum valve 63.
