Description

Technical Field

[0001] This utility model belongs to the technical field of photovoltaic module junction box installation equipment, and in particular relates to a junction box feeding and installation device. Background Technology

[0002] With the continuous development of the photovoltaic industry, production efficiency, quality stability, and automation levels are receiving increasing attention. Junction box installation for photovoltaic modules, as a crucial step in the manufacturing process, directly impacts the electrical performance, quality control, and overall production efficiency of the modules. In recent years, the application of robotics technology in photovoltaic module production has gradually increased, especially in the automation of junction box installation, where material feeding technology has become a key area of ​​technological development.

[0003] Photovoltaic junction box installation and feeding machines (especially automated equipment used in photovoltaic production lines) have become key technologies in recent years for the photovoltaic industry to improve production efficiency, reduce manual labor, and lower product defect rates. While these devices are widely used in photovoltaic module production, they also have some shortcomings: material feeding is done via a feeding trolley, followed by gripping by a three-axis linear module; the junction boxes are layered, resulting in a slow gripping speed; and the photovoltaic module positioning system is unstable, leading to displacement during junction box installation and improper installation. Summary of the Invention

[0004] The purpose of this utility model is to provide a junction box feeding and installation device to solve the problems existing in the prior art.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A junction box feeding and installation device includes a feeding mechanism and an installation mechanism. The feeding mechanism includes two pneumatic grippers with a bent middle section and a semi-circular gripping groove at the gripping end. The installation mechanism includes an installation frame, an installation conveyor, four positioning cylinders, four limit cylinders, four rollers, and four right-angle cylinders. The installation conveyor is fixed on the installation frame. The four positioning cylinders are symmetrically fixed on the installation frame on the front and rear sides of the installation conveyor. The four rollers are vertically installed on the output ends of the four positioning cylinders. The four limit cylinders are symmetrically fixed on the installation frame on the left and right sides of the installation conveyor. The four right-angle cylinders are installed on the output ends of the four limit cylinders.

[0007] Furthermore, the feeding mechanism also includes a feeding frame, a feeding robot, gripper cylinders, four feeding conveyors, two transfer conveyors, and two feeding vision recognition devices. The four feeding conveyors are installed at the lower front end of the feeding frame. The feeding robot is located on the feeding frame at the output end of the four feeding conveyors. The gripper cylinders are installed at the output end of the feeding robot. The feeding vision recognition devices are fixed on the feeding frame above the feeding conveyors. One feeding vision recognition device corresponds to two feeding conveyors. The input ends of the two transfer conveyors are close to the feeding robot and higher than the feeding conveyors. The output ends of the two transfer conveyors extend out of the feeding frame.

[0008] Furthermore, the input end of the feeding conveyor is close to the front end of the feeding frame, and the output end of the feeding conveyor is close to the feeding robot.

[0009] Furthermore, the fixed end of the pneumatic gripper is provided with a mounting plate perpendicular to the pneumatic gripper. The two pneumatic grippers are fixed to the two output ends of the gripper cylinder respectively through the mounting plate. The gripping slots of the two pneumatic grippers are arranged opposite each other and form a circle when they are close to each other.

[0010] Furthermore, the fixed end and gripping end of the pneumatic gripper are both perpendicular to the gripper cylinder, and the angle between the middle part of the pneumatic gripper and the fixed end and gripping end of the pneumatic gripper is 150 degrees.

[0011] Furthermore, the installation mechanism also includes two installation robots and two installation vision recognition devices. The installation frame is located at the rear end of the feeding frame. The installation position of the installation conveyor is lower than that of the transfer conveyor. The two installation robots are located on the left and right sides of the two transfer conveyors, respectively, and the two installation vision recognition devices are located above the installation conveyor.

[0012] Furthermore, the conveying direction of the installed conveyor is perpendicular to the conveying direction of the transfer conveyor.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model uses visual recognition for material feeding to identify disordered materials. Workers do not need to neatly hang the disordered junction boxes on the material feeding trolley. They only need to place the junction boxes into the inner material boxes in disorder and then place the material boxes on the material feeding conveyor, thereby reducing workload and improving material feeding efficiency.

[0015] 2. By using a bent pneumatic gripper to avoid obstruction, the large end of the feeding robot can prevent it from hindering the scanning of the feeding vision recognition device above when gripping the junction box.

[0016] 3. The photovoltaic modules are clamped and fixed by positioning cylinders, limit cylinders, and right-angle cylinders to prevent displacement of the photovoltaic modules during installation and ensure proper installation. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with specific embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the scope of the utility model.

[0025] like Figure 1-6As shown, a junction box feeding and installation device includes a feeding mechanism and an installation mechanism. The feeding mechanism includes two pneumatic grippers 1, each with a bent middle section. This design is for obstacle avoidance; if a straight type were used, the larger end of the feeding robot 10 would obstruct the scanning of the feeding vision recognition device 14 above when gripping the junction box. Therefore, the bending is used to avoid obstacles. The gripping end of the pneumatic gripper 1 has a semi-circular gripping groove 2 for holding the junction box in place. The installation mechanism includes an installation frame 3, an installation conveyor 4, four positioning cylinders 5, four limit cylinders 6, four rollers 7, and four right-angle cylinders 8. The installation conveyor 4 is fixed on the installation frame 3. The four positioning cylinders 5 are symmetrically fixed on the installation frame 3 on the front and rear sides of the installation conveyor 4. The four rollers 7 are respectively vertically installed on the output ends of the four positioning cylinders 5. After the four positioning cylinders 5 are activated, the rollers 7 abut against both sides of the photovoltaic module. The four limit cylinders 6 are symmetrically fixed on the installation frame 3 on the left and right sides of the installation conveyor 4. The four right-angle cylinders 8 are respectively installed on the output ends of the four limit cylinders 6. After the four limit cylinders 6 and the four right-angle cylinders 8 are activated, they clamp the photovoltaic module. If the photovoltaic module slides, the rollers 7 will rotate accordingly.

[0026] The feeding mechanism also includes a feeding frame 9, a feeding robot 10, a gripper cylinder 11, four feeding conveyors 12, two transfer conveyors 13, and two feeding vision recognition devices 14. The four feeding conveyors 12 are installed at the lower front end of the feeding frame 9. Since two types of junction boxes need to be installed on the photovoltaic modules, the four feeding conveyors 12 are grouped in pairs, with each group holding one type of junction box. The feeding robot 10 is located on the feeding frame 9 at the output end of the four feeding conveyors 12. The gripper cylinder 11 is installed at the output end of the feeding robot 10. The feeding vision recognition devices 14 are fixed on the feeding frame 9 above the feeding conveyors 12, with one feeding vision recognition device 14 corresponding to two feeding conveyors 12. The input ends of the two transfer conveyors 13 are close to the feeding robot 10 and higher than the feeding conveyors 12, while the output ends of the two transfer conveyors 13 extend out of the feeding frame 9. The material feeding visual recognition device 14 is capable of disordered recognition, which is a prior art technology. It controls the material feeding robot 10 to grasp disordered objects by recognizing them. Compared with the prior art, the operator does not need to neatly hang the junction boxes that do not need to be stacked on the material feeding trolley, but only needs to place the boxes containing disordered materials on the material feeding conveyor 12.

[0027] The input end of the feeding conveyor 12 is close to the front end of the feeding frame 9, and the output end of the feeding conveyor 12 is close to the feeding robot 10.

[0028] The fixed end of the pneumatic gripper 1 is provided with a mounting plate 15 perpendicular to the pneumatic gripper 1. The two pneumatic grippers 1 are fixed to the two output ends of the gripper cylinder 11 respectively through the mounting plate 15. The gripping slots 2 of the two pneumatic grippers 1 are arranged opposite each other and form a circle when they are close to each other, thereby clamping the junction box.

[0029] The fixed end and the gripping end of the pneumatic gripper 1 are both perpendicular to the gripper cylinder 11. The angle between the middle part of the pneumatic gripper 1 and the fixed end and the gripping end of the pneumatic gripper 1 is 150 degrees, so as to avoid collision.

[0030] The installation mechanism also includes two installation robots 16 and two installation vision recognition devices 17. The installation frame 3 is located at the rear end of the feeding frame 9. The installation position of the installation conveyor 4 is lower than that of the transfer conveyor 13. The two installation robots 16 are located on the left and right sides of the two transfer conveyors 13 respectively, and the two installation vision recognition devices 17 are located above the installation conveyor 4.

[0031] The conveying direction of the installed conveyor 4 is perpendicular to the conveying direction of the transfer conveyor 13.

[0032] The working principle of this utility model is as follows:

[0033] In use, the unordered junction box is placed on the feeding conveyor 12, and the photovoltaic module is placed on the installation conveyor 4 and transported to the rear end of the feeding frame 9. The positioning cylinder 5 extends, and the roller 7 abuts against both sides of the photovoltaic module. The limiting cylinder 6 extends, and the right-angle cylinder 8 actuates, so that its clamping end abuts against the other two sides of the photovoltaic module. The limiting cylinder 6 retracts, thereby clamping the photovoltaic module between the right-angle cylinders 8. During this process, the photovoltaic module may slip, and the roller 7 rotates as the photovoltaic module slips.

[0034] Two types of junction boxes need to be installed on the photovoltaic modules. Therefore, the four feeding conveyors 12 are arranged in pairs, with each pair holding one type of junction box. The feeding vision recognition device 14 performs posture recognition and path planning for the junction boxes in the material boxes. The feeding robot 10 moves and uses the pneumatic gripper 1 to grab the junction boxes in the material box and place them on the transfer conveyor 13 to transport them to the vicinity of the installation robot 16. The installation vision recognition device 17 performs posture recognition and path planning for the junction boxes on the transfer conveyor 13. The installation robot 16 moves to install the junction boxes on the photovoltaic modules. After installation, the positioning cylinder 5, limit cylinder 6, and right-angle cylinder 8 are reset. The installation conveyor 4 moves to transport the photovoltaic modules to the next process.

[0035] When there are no junction boxes in the material boxes on the same feeding conveyor 12, the feeding conveyor 12 rotates in the opposite direction to send the empty material boxes away, and the staff places the new material boxes containing junction boxes on the feeding conveyor 12.

[0036] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention.
