Description

Technical Field

[0001] The invention relates to the technical field of solar panel processing, in particular to a belt-driven conveyor for solar panel processing. Background Art

[0002] Solar panels are a type of photoelectric semiconductor wafer that uses sunlight to generate electricity directly. They are assembled from a number of solar cells on a board in a certain way. They are the core of the solar power generation system. The processing of solar panels will go through multiple processes such as dicing, stringing, lamination, testing, lamination, framing, and packaging. For the testing process, the solar panels are transported by a belt-driven conveyor, and then tested by a tester.

[0003] When the existing belt-driven conveyor for detecting and processing some solar panels is used, the detector is fixed on the bracket of the belt-driven conveyor. When the solar panel is conveyed to the bottom of the detector through the transmission belt in the belt-driven conveyor, the solar panel can be inspected by the detector. During this process, since the position of the detector is fixed, in order to ensure the detection effect of the solar panel, the solar panel will stay under the detector. The more solar panels are inspected, the longer the overall time it takes for the solar panel to stay under the detector. In this case, the detection efficiency of the solar panel will be reduced. For this reason, we propose a belt-driven conveyor for processing solar panels. Summary of the invention

[0004] A technical problem to be solved by the present application is that, since the position of the detector is fixed, in order to ensure the detection effect of the solar panel, the solar panel will stay under the detector. The more solar panels are detected, the longer the overall time it takes for the solar panel to stay under the detector. In this case, the detection efficiency of the solar panel will be reduced.

[0013] In some embodiments, the conveyor belt is a mesh belt with a mesh diameter of 3 mm.

[0015] In some embodiments, the adjustment mechanism includes a bidirectional screw rod rotatably connected to the inner surface of the bracket, the bidirectional screw rod is threadedly connected to the conveying module, and a hand wheel is provided at one end of the bidirectional screw rod.

[0016] In some embodiments, the transmission ratio of the bidirectional screw is 1:10.

[0017] In some embodiments, the lifting mechanism includes a threaded sleeve arranged on the outer surface of the support plate, the inner surface of the threaded sleeve is threadedly connected to a threaded rod, the outer surface of the threaded rod is rotatably connected to a support block, the support block is fixedly connected to the bracket, a limit rod is arranged on the lower surface of the support plate, the limit rod is slidably connected to the bracket, and a transmission mechanism is arranged at the lower end of the threaded rod.

[0021] The present invention has at least the following beneficial effects:

[0022] 1. Through the arrangement of the conveying module and the driving shaft, the solar panels can be normally conveyed. During the conveying process of the solar panels, the detector in the detection mechanism that can move synchronously with the solar panels for a distance can be used to perform X-ray detection on the solar panels. When detecting solar panels of different sizes, the position of the conveying module can be adjusted through the adjustment mechanism to ensure the normal conveying of solar panels of different sizes. At the same time, through the cooperation of the lifting mechanism and the transmission mechanism, the height of the detection mechanism and the support plate can be adjusted to ensure the accuracy and effectiveness of the detection of solar panels of different sizes. During the conveying process of solar panels of different sizes, the position of the solar panel can be sensed and detected through the laser sensor in the detection mechanism, and the start and stop of the driving motor in the detection mechanism can be controlled so that the detector in the detection mechanism is located above the middle of the solar panel and then moves synchronously with the solar panel for a distance. During the synchronous movement, the solar panel is subjected to X-ray detection. Compared with the fixed position of the detector, in order to ensure the detection effect of the solar panel, the solar panel will stay briefly under the detector to complete the detection of the solar panel, which can shorten the overall time consumption of detecting a large number of solar panels, improve the detection efficiency of a large number of solar panels, and thus improve the processing efficiency of solar panels.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example 1

[0033] See also Figure 1-6 , the present invention provides a technical solution:

[0034] A belt-driven conveyor for processing solar panels, comprising a bracket 1, and also comprising:

[0035] A conveying module 2, the conveying module 2 is movably arranged on the outer surface of the bracket 1;

[0036] A driving shaft 3, the driving shaft 3 is rotatably connected to the inner surface of the bracket 1, and there are two driving shafts 3, and both driving shafts 3 are slidably connected to the conveying module 2;

[0037] A support plate 4, wherein the support plate 4 is arranged above the bracket 1;

[0038] A detection mechanism 5, which is arranged on the upper surface of the support plate 4 and is used for detecting the solar panel;

[0039] An adjusting mechanism 6, which is rotatably connected to the inner surface of the bracket 1 and is threadedly connected to the conveying module 2, for adjusting the position of the conveying module 2;

[0040] The lifting mechanism 7 is arranged on the outer surface of the support plate 4 , and the lifting mechanism 7 is slidably connected to the bracket 1 for adjusting the height of the support plate 4 .

[0041] The conveying module 2 is mainly composed of a support frame, a conveying wheel and a conveying belt. It is a prior art. One end of any driving shaft 3 can be fixedly connected to the output end of an external motor. When the external motor is started, the driving shaft 3 can be driven to rotate, so that the conveying wheel and the conveying belt in the conveying module 2 can be rotated to transport the solar panels. The driving shaft 3 is slidingly connected to the conveying module 2, that is, the driving shaft 3 is slidingly connected to the conveying wheel in the conveying module 2, which can realize the adjustment of the position of the conveying module 2, and after the adjustment is completed, the conveying wheel and the conveying belt can be driven to rotate by rotating the driving shaft 3.

[0042] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the detection mechanism 5 includes a fixed frame 51 arranged on the upper surface of the support plate 4, the inner surface of the fixed frame 51 is rotatably connected to two driving rollers 52, the outer surfaces of the two driving rollers 52 are provided with a conveyor belt 53, the outer surface of the conveyor belt 53 is provided with two detectors 54, the outer surface of the fixed frame 51 is provided with a driving motor 55, the output end of the driving motor 55 is fixedly connected to one of the driving rollers 52, and the lower surface of the support plate 4 is provided with a laser sensor 56.

[0043] Detector 54 is an EL detector, which is an instrument used for detecting potential defects of solar panels. Its features include high-resolution images, high-performance index, compact structure, simple operation, multi-functional use, and safety and reliability. This detector uses a high-definition camera and unique image processing software to capture high-resolution images of the inside of the solar panel and process the images into high-quality photos to clearly present the internal state of the panel. Therefore, if the size of the solar panel changes, in order to ensure the accuracy and effectiveness of the detection, it is necessary to adjust the distance between the EL camera and the solar panel to adapt to the new size, so as to obtain a clear image and accurately analyze and evaluate the solar panel.

[0044] Specifically, Figure 5 and Figure 6 As shown, the conveyor belt 53 is a mesh belt with a mesh diameter of 3 mm. Compared with a solid belt, the mesh belt is lighter, can reduce the burden on the system, and facilitates the passage of light to ensure the brightness of the detection area.

[0045] Specifically, Figure 5 and Figure 6 As shown, the outer surface of the fixing frame 51 above the conveyor belt 53 is provided with cleaning cotton 8, through which the dust particles attached to the surface of the detector 54 can be cleaned to ensure the use effect of the detector 54.

[0046] Specifically, Figure 1and Figure 3 As shown, the adjustment mechanism 6 includes a bidirectional screw rod 61 rotatably connected to the inner surface of the bracket 1 , the bidirectional screw rod 61 is threadedly connected to the conveying module 2 , and a hand wheel 62 is provided at one end of the bidirectional screw rod 61 .

[0047] Specifically, Figure 1 and Figure 3 As shown, the transmission ratio of the bidirectional screw 61 is 1:10. When the bidirectional screw 61 rotates one circle, the conveying module 2 can move 10 mm, so that the position of the conveying module 2 can be quickly adjusted.

[0048] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, the lifting mechanism 7 includes a threaded sleeve 71 arranged on the outer surface of the support plate 4, the inner surface of the threaded sleeve 71 is threadedly connected with a threaded rod 72, the outer surface of the threaded rod 72 is rotatably connected with a support block 73, the support block 73 is fixedly connected to the bracket 1, a limit rod 74 is arranged on the lower surface of the support plate 4, the limit rod 74 is slidably connected to the bracket 1, and a transmission mechanism 9 is arranged at the lower end of the threaded rod 72.

[0049] Specifically, Figure 1 and Figure 3 As shown, there are multiple limiting rods 74, which can improve the stability of the device.

[0050] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, the transmission mechanism 9 includes a bevel gear 1 91 arranged at the lower end of the threaded rod 72 , and the outer surface of the bevel gear 1 91 is meshedly connected with a bevel gear 2 92 , and the bevel gear 2 92 is fixedly connected to the bidirectional screw rod 61 .

[0051] When in use, the external motor is started to rotate the driving shaft 3, and then the driving shaft 3 is rotated to drive the conveying wheel and the conveying belt in the conveying module 2 to rotate, so as to convey the solar panel on the conveying belt. At the same time, the driving motor 55 is started, and the output end of the driving motor 55 is rotated to drive the driving roller 52 and the rotating conveying belt 53 to rotate, and then the conveying belt 53 is rotated to drive the detector 54 to rotate. When the solar panel is transported to the predetermined position, the detector 54 is located at the center position above the solar panel, and then it moves with the solar panel. During the movement, the solar panel is X-rayed, and then another detector 54 is used to detect the next solar panel, and the detection operation is completed in an alternating cycle.

[0052] When the sizes of the solar panels to be detected are different, the hand wheel 62 is rotated, and the bidirectional screw rod 61 is driven to rotate by the rotation of the hand wheel 62, and then the conveying module 2 is moved to a suitable position by the rotation of the bidirectional screw rod 61. At the same time, the bevel gear 2 92 can be driven to rotate by the rotation of the bidirectional screw rod 61, and then the bevel gear 1 91 is driven to rotate by the rotation of the bevel gear 2 92, and then the threaded rod 72 is driven to rotate, and then the threaded sleeve 71 is driven to move by the rotation of the threaded rod 72, and then the support plate 4 is driven to move up or down to a suitable position, so that the fixing frame 51, the driving roller 52, the conveyor belt 53, the detector 54, the driving motor 55 and the laser sensor 56 are moved up or down to a suitable position. In this process, the support plate 4 is stably moved by the limit rod 74;

[0053] Then, the conveying module 2 is moved to the appropriate position to convey the solar panels of different sizes. As the size of the solar panels changes, the laser sensor 56 can be used to sense and detect the solar panels. When it is detected that the solar panel moves to the predetermined position, that is, the detector 54 is at the center position above the solar panel, the drive motor 55 is started to move the detector 54 with the solar panel. During the movement, the solar panel is subjected to X-ray detection. After the next solar panel is sensed by the laser sensor 56, the drive motor 55 is started again to move the other detector 54 with the solar panel. During the movement, the solar panel is subjected to X-ray detection.

[0054] For the above operations, to generate a motor control program that stops at a fixed period and starts according to the sensor signal, you can consider using a timer (in a PLC, microcontroller, or any control system that supports timing functions) to control the stop period, and use a sensor (such as a proximity switch, photoelectric sensor, etc.) to detect the start condition. The following is a simplified algorithm flow to illustrate this process:

[0055] / / Assume that there are the following global variables

[0056] / / motor_state: motor status (stop / run)

[0057] / / sensor_signal: sensor signal (high level indicates that the start condition is met)

[0058] / / timer: timer, used to achieve fixed period stop

[0059] / / cycle_time: duration of each running cycle (seconds)

[0060] initialization(){

[0061] motor_state = STOPPED; / / The initial state is stopped

[0062] sensor_signal = read sensor signal(); / / initial read sensor signal

[0063] timer=0; / / reset the timer

[0064] cycle_time = 10; / / Assume each cycle runs for 10 seconds

[0065] }

[0066] MainLoop(){

[0067] while(true){

[0068] if(sensor_signal == HIGH){ / / If the sensor signal is high

[0069] if(motor_state==STOPPED){ / / If the motor is currently stopped, start the motor();

[0070] motor_state = RUNNING; / / Update the motor state to running

[0071] timer=0; / / reset the timer

[0072] }

[0073] }

[0074] if (motor_state == RUNNING) {

[0075] timer+=readtimeincrement(); / / update timer

[0076] if(timer>=cycle_time){ / / If the running cycle is reached, stop the motor();

[0077] motor_state = STOPPED; / / Update the motor state to stop

[0078] / / Optional: reset sensor signal or other logic after stopping

[0079] }

[0080] }

[0081] / / Check the sensor signal periodically in case the signal goes low while the motor is running

[0082] if(sensor_signal==LOW&&motor_state==RUNNING){

[0083] stopMotor();

[0084] motor_state = STOPPED;

[0085] }

[0086] / / Delay for a short time to avoid excessive CPU usage

[0087] shortDelay();

[0088] / / Reread the sensor signal (depending on actual needs, it may not be necessary to read it every loop)

[0089] sensor_signal = read sensor signal();

[0090] }

[0091] }

[0092] / / The following are the functions that need to be implemented

[0093] Read sensor signal(){

[0094] / / Implement the logic of reading sensor signals

[0095] / / Return HIGH or LOW

[0111] Example 2

[0112] See also Figure 7 , the present invention provides a technical solution:

[0113] Different from the first embodiment, the support plate 4 and the limiting rod 74 are both made of polypropylene plastic.

[0114] Polypropylene plastic has the characteristics of light weight, corrosion resistance and high hardness. When the support plate 4 and the limit rod 74 move up or down, it can save the effort required for the height adjustment operation, thereby facilitating the height adjustment of the detection mechanism 5.
