Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic panel testing technology, specifically relating to an automatic calibration device for a testing machine. Background Technology

[0002] In the photovoltaic panel production and testing process, testing machines need to be calibrated regularly using standard photovoltaic panels to ensure the accuracy of testing parameters such as power and electrical performance. Currently, the industry relies heavily on manual operation for the calibration of testing machines, which presents significant technical shortcomings.

[0003] Manual transport and positioning are inefficient, requiring manual handling of standard photovoltaic panels to their designated positions on the testing machine. Each calibration requires multiple adjustments to the panel's position, which is not only time-consuming but also prone to causing panel misalignment due to uneven manual force. Furthermore, the calibration process lacks continuity; the transport, gripping, fixing, and lifting testing of standard photovoltaic panels are independent processes requiring manual coordination, which can easily lead to interruptions and affect calibration efficiency. When manually placing photovoltaic panels, it is difficult to accurately align them with the testing machine's workstations, and the inability to provide real-time feedback on panel posture deviations affects the accuracy of calibration data, consequently impacting the testing machine's subsequent testing precision.

[0004] Therefore, there is an urgent need for a calibration device that can automatically transport, grab, position, and lift standard photovoltaic panels to solve the efficiency and accuracy problems of the existing manual calibration mode. Utility Model Content

[0029] The platform lifting device 4 includes a base plate 41 connected to the base 1. A test frame 45 is provided on the upper side of the base plate 41. A lifting cylinder 42 is provided inside the test frame 45. A lifting platform 46 is provided on the piston rod of the lifting cylinder 42. A limiting cylinder 43 is provided on one side of the lifting cylinder 42. A limiting plate 44 is provided on the limiting cylinder 43. The lifting cylinder 42 is installed on the base plate 41.

[0030] Specifically, the base plate 41 is connected to the base 1, providing stable support for the entire lifting structure; the test frame 45 limits the range of motion of the lifting cylinder 42 and the lifting platform 46 to prevent overtravel; the lifting cylinder 42 drives the lifting platform 46 to rise and fall, achieving height matching between the photovoltaic panel and the testing position of the testing machine; the limit cylinder 43 drives the limit plate 44 to extend, fixing the lifting platform 46 during lifting to prevent it from shaking and ensuring the stability of the photovoltaic panel lifting process.

[0031] The moving device 5 includes a motor 51 connected to the mold conveying device 2. The output end of the motor 51 is connected to a lead screw 52. One end of the lead screw 52 is connected to a fixed block 54. A slider 53 is provided on the lead screw 52. A connecting plate 55 is provided on the slider 53. A pneumatic slide table 57 is provided on the connecting plate 55. A pneumatic slider 58 is provided on the pneumatic slide table 57.

[0032] Specifically, motor 51 is the power source, which drives lead screw 52 to rotate, causing slider 53 to move along lead screw 52, ​​thereby driving connecting plate 55 and subsequent components to move synchronously; fixed block 54 fixes the end of lead screw 52; pneumatic slide table 57 drives pneumatic slider 58 to move laterally, and upper slider 56 assists connecting plate 55 to slide smoothly, ensuring that gripping device 6 moves accurately to the target position.

[0033] The gripping device 6 includes a gripping cylinder 61 connected to a pneumatic slider 58. The gripping cylinder 61 is provided with a mounting plate 62. The mounting plate 62 is provided with a rotary motor 63. The output end of the rotary motor 63 is connected to a fixed plate 66. The fixed plate 66 is provided with a suction cup 64. A vision component 65 is installed on the fixed plate 66.

[0034] Specifically, the gripping cylinder 61 drives the mounting plate 62 and subsequent components to rise and fall, coordinating with the gripping action; the rotating motor 63 drives the fixing plate 66 to rotate, correcting the photovoltaic panel's posture and making it fit for placement; the suction cup 64 directly contacts and adsorbs the photovoltaic panel, achieving stable gripping; the vision component 65 identifies the position of the photovoltaic panel, providing positioning basis for the gripping action and ensuring accurate gripping.

[0035] The vision component 65 is connected to the PLC controller, and multiple suction cups 64 are evenly distributed on the fixed plate 66. Specifically, the vision component 65 transmits the position and attitude data of the photovoltaic panel to the PLC controller, providing precise control data for the action of the gripping device 6; the multiple evenly distributed suction cups 64 ensure that the photovoltaic panel is subjected to balanced force, avoiding damage caused by excessive local force, while also enhancing gripping stability and preventing it from falling off during movement.

[0036] The connecting plate 55 is slidably connected to both sides of the mold conveying device 2, and the upper slider 56 is located on the upper side of the mold conveying device 2. Specifically, the connecting plate 55 is slidably connected to both sides of the mold conveying device 2 to form a guide structure, which restricts its movement to a fixed direction and avoids horizontal deviation; the upper slider 56 is located on the upper side of the mold conveying device 2 and cooperates with the connecting plate 55 to form double support, reducing swaying during movement.

Specifically, the display 11 is connected to the PLC controller to display information such as the device's operating status and calibration progress in real time; it also allows operators to input commands to the PLC controller through the display.

[0038] Working principle: After the device is started, the belt conveyor 3 transports the photovoltaic panel to the designated position, and then the belt conveyor 3 stops running; the vision component 65 identifies the position of the photovoltaic panel and transmits the position signal to the PLC controller; the PLC controller controls the movement of the moving device 5, the motor 51 drives the lead screw 52 to rotate, which drives the slider 53, the connecting plate 55 and the pneumatic slide table 57 to move to the position of the photovoltaic panel; the pneumatic slide table 57 drives the pneumatic slider 58 to move, so that the gripping device 6 moves to directly above the photovoltaic panel, and the rotating motor 63 rotates to ensure that the suction cup 64 grips the position of the photovoltaic panel;

[0039] The gripping cylinder 61 descends in conjunction with the suction cup 64, which then picks up the photovoltaic panel. The rotating motor 63 then rotates to calibrate the orientation of the photovoltaic panel. The moving device 5 then moves the gripping device 6 above the photovoltaic panel fixing plate 7 of the mold conveying device 2. The pneumatic slide 57 descends, and the suction cup 64 releases the photovoltaic panel, placing it inside the photovoltaic panel fixing plate 7. The mold conveying device 2 then activates, transporting the photovoltaic panel fixing plate 7 and the photovoltaic panel to the corresponding position on the platform lifting device 4 in the middle.

[0040] The PLC controller controls the limit cylinder 43 to move, and the limit plate 44 extends to limit the lifting platform 46; then the lifting cylinder 42 moves, and its piston rod drives the lifting platform 46 to rise, lifting the photovoltaic panel to the testing position of the testing machine, and cooperating with the testing machine to complete the test.

[0041] After the calibration test is completed, the lifting cylinder 42 drives the lifting platform 46 to descend and reset, and the limit cylinder 43 drives the limit plate 44 to retract; the mold conveying device 2 conveys the photovoltaic panel fixing plate 7 and photovoltaic panel components to the next position.
