Description

Technical Field

[0001] The present invention relates to the field of photovoltaic product processing, and in particular to a method for placing a wired junction box. Background Art

[0002] In the production process of photovoltaic modules, after the busbars welded on the photovoltaic module board are lifted up, the junction box needs to be aligned with the busbars for plugging and installation, so that the busbars can be welded to the junction box to achieve current connectivity and output.

[0003] Currently, there are two main types of junction boxes: wired junction boxes with connecting wires (wired junction boxes) and wireless junction boxes that retain only the box structure. Wired junction boxes are installed on both sides of a PV panel to form output terminals, while wireless junction boxes are installed in the center of a PV panel to create a current path. Both types of junction boxes require accurate positioning of the front and back before installation to ensure accurate handling by a robot or other gripping device.

[0004] In the prior art, the method commonly used for feeding wired junction boxes is to feed a material rack with orderly arranged wired junction boxes to a feeding mechanism. This method requires manual prior arrangement and loading of disordered wired junction boxes so that the front and back directions of the wired junction boxes placed on the material rack are consistent. Therefore, the overall process flow is relatively cumbersome.

[0005] Therefore, how to solve the above-mentioned deficiencies in the prior art has become the subject to be studied and solved by the present invention. Summary of the Invention

[0006] The purpose of the present invention is to provide a method for placing a wired junction box.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is:

[0008] A method for placing a wired junction box, comprising the following steps:

[0009] S1. Transport the wired junction box to a loading station;

[0010] S2. Grabbing the wired junction box from the loading station using a grabbing structure of a straightening device;

[0011] S3. Hang the grabbed wired junction box and perform visual inspection on the hung wired junction box, using machine vision to determine the current orientation of the wired junction box; then, use the alignment device to adjust and align the wired junction box in a targeted manner according to the current orientation of the wired junction box, so that the wired junction box is placed upward in the set orientation for unloading;

[0012] Among them, the adjustment and alignment are realized through an adjustment structure;

[0013] The grasping structure is a jaw assembly, and the adjustment structure is an actuator for driving the jaws to act in different ways and enabling the wired junction box to be placed in an aligned manner.

[0014] In a further technical solution, the grasping structure is a double-jaw assembly. The double-jaw assembly includes two pairs of jaws. When grasping in step S2, the first pair of jaws of the double-jaw assembly clamps the wire of the wired junction box. In step S3, the wire of the wired junction box is suspended by closing the second pair of jaws, and at the same time, the first pair of jaws releases the wired junction box, causing the wired junction box to hang naturally due to its own weight.

[0015] In a further technical solution, in S3, the two pairs of jaws of the double-jaw assembly are arranged adjacent to each other. The first pair of jaws and the second pair of jaws are respectively controlled and driven by corresponding jaw cylinders. The second pair of jaws is in the shape of opposite hooks, and the two jaw cylinders are fixedly arranged relative to each other.

[0016] In a further technical solution, in S3, before the visual inspection of the wired junction box, the first jaw group is clamped again, and the clamping surface of the first jaw group is pushed into the wire of the wired junction box to keep the position and posture of the wired junction box stable.

[0017] In a further technical solution, the adjustment structure of the double-jaw assembly is a robotic arm. The double-jaw assembly is mounted on the robotic arm. The method for adjusting the orientation of the wired junction box is as follows:

[0018] First, open the first pair of jaws to clamp and position the wired junction box to prevent it from rotating due to its own weight; then drive the rotation of the robotic arm to turn the wired junction box upward in the required orientation; finally, drive the robotic arm to descend to place the wired junction box, thus realizing the alignment adjustment of the wired junction box.

[0019] In a further technical solution, the adjustment structure of the double-jaw assembly is a robotic arm. The double-jaw assembly is mounted on the robotic arm. The method for adjusting the orientation of the wired junction box is as follows:

[0020] First, grasp the wired junction box with the second pair of jaws. At this time, the wired junction box is in a freely swinging state; then slowly lower the wired junction box so that its bottom touches a placement area; finally, move the upper or lower end of the wired junction box according to the required orientation to make its required surface face upward, and at the same time continue to slowly lower it until the wired junction box is placed in the required orientation.

[0021] In a further technical solution, the adjustment structure of the double-jaw assembly is a robotic arm. The double-jaw assembly is mounted on the robotic arm. The method for adjusting the orientation of the wired junction box is as follows:

[0022] First, open the first pair of jaws and close the second pair of jaws at the same time. Control the robotic arm to swing back and forth according to the direction of the junction box visual inspection. When the wired junction box swings to the required side facing up, lower the robotic arm so that the bottom of the wired junction box touches the placement area; finally, continue to slowly descend to place the wired junction box in the required orientation.

[0023] A further technical solution is that the double-jaw assembly is driven by a two-axis or three-axis linear drive mechanism including Z-axis movement, the adjustment structure is a drive cylinder fixed to the drive mechanism, the double-jaw assembly is rotatably arranged on the drive mechanism, and the piston rod of the cylinder acts on one side of the double-jaw assembly. The method for adjusting the direction of the wired junction box is as follows:

[0024] First, open the first pair of jaws to clamp the wired junction box and position it to prevent it from rotating due to its own weight; then drive the cylinder to extend the piston rod to support the side of the double-jaw assembly, so that the double-jaw assembly and the positioned wired junction box are tilted together, thereby making the required side of the wired junction box face upward; finally, drive the double-jaw assembly to descend, place the wired junction box and release the first pair of jaws, thereby completing the alignment adjustment of the wired junction box.

[0025] A further technical solution, in S3, is to place the wired junction box on a blanking conveyor line for blanking; further comprising:

[0026] S4. Visually inspect the wired junction boxes on the unloading conveyor line to check whether they are oriented as required or whether they have defects. If any of the above two problems exist, the boxes are judged as unqualified and are discharged for recycling.

[0027] The working principle and advantages of the present invention are as follows:

[0028] The present invention enables the unordered gripping of wired junction boxes, allowing them to be gripped and aligned even when placed in disorder, eliminating the need for manual sorting. After gripping a wired junction box, the current gripping position can be visually identified, and the box can be aligned and placed in the appropriate unloading position based on the recognition result. Compared to existing technologies, the present invention significantly increases the automation rate of the system, shortens overall working time, and improves efficiency.

[0053] See the attached Figure 1 As shown, a method for placing a wired junction box includes the following steps:

[0054] S1. Transport the wired junction box 1 to the loading station 3;

[0055] S2. Grasp the wired junction box 1 from the loading station 3 through the grasping structure of the alignment device;

[0056] S3. Suspend the grasped wired junction box 1, and conduct visual inspection on the suspended wired junction box 1, using machine vision to judge the current orientation of the wired junction box 1; then, the alignment device adjusts and aligns it in a targeted manner according to the current orientation of the wired junction box 1, so that the wired junction box 1 is placed upward in a set orientation for discharging.

[0057] Preferably, as Figures 2 - 5 shown, the alignment device includes a double-jaw assembly 4 (grasping structure) and a driving mechanism (the robotic arm 14 in the figure) for driving its movement; the double-jaw assembly 4 is driven by the driving mechanism to move to the loading station 3 in sequence to pick up materials, move to the inspection station 5 to inspect the orientation of the grasped wired junction box 1, and move to the discharging station 6 to discharge materials; wherein, the double-jaw assembly 4 includes two pairs of jaws, namely the first pair of jaws 4a for fastening or clamping the wired junction box 1 and the second pair of jaws 4b for suspending the wired junction box 1; the driving parts of the two pairs of jaws are relatively fixedly arranged, and the two pairs of jaws are arranged in a mutually attached or close manner.

[0058] Among them, the driving parts of the two pairs of jaws can be cylinders 7a and 7b.

[0059] The visual inspection is realized by the first inspection camera 8, which is arranged corresponding to the inspection station 5 and is used to photograph the orientation of the wired junction box 1 grasped by the second pair of jaws 4b.

[0060] Preferably, in S1, the feeding box 2 loaded with the wired junction box 1 is conveyed to the loading station 3 through the horizontal conveyor 9.

[0061] Preferably, in S2, the grasping structure is the double-jaw assembly 4. When grasping, first, the first pair of jaws 4a fasten and lift the annular wire 1a of the wired junction box 1, and then the second pair of jaws 4b closes to suspend the wire 1a of the wired junction box 1 therein. At the same time, the first pair of jaws 4a releases the wired junction box 1, so that the wired junction box 1 naturally hangs down due to its own weight.

[0062] Preferably, in S3, the wired junction box 1 suspended in the second pair of jaws 4b is moved to the first inspection camera 8 for photographing for visual inspection.

[0063] Preferably, in S3, before the wired junction box 1 is photographed, the first jaw group 4a is clamped again, and the clamping surface of the first jaw group 4a is pushed into the wire 1a of the wired junction box 1 to keep the position and posture of the wired junction box 1 stable. The wire 1a of the wired junction box 1 and the junction box body are relatively fixed.

[0064] By clamping with the first jaw group 4a, the state of the wired junction box 1 can be quickly stabilized, facilitating photographing by the first detection camera 8, avoiding the problem of blurred camera focus caused by the shaking of the wired junction box 1, and thus accelerating the detection accuracy and efficiency.

[0065] Wherein, the alignment device further includes an adjustment structure for adjusting the orientation of the wired junction box 1. This adjustment structure is the driving mechanism of the double jaw assembly 4, or this adjustment structure is fixedly arranged on the driving mechanism, and its acting end acts on the double jaw assembly 4.

[0066] The first detection camera 8 captures the front and back orientation information of the wired junction box 1 and feeds it back to the system. The system determines whether it is necessary to adjust the orientation of the wired junction box 1 through the adjustment structure and align it.

[0067] Preferably, in S3, if the current orientation of the wired junction box 1 is different from the system setting (that is, it does not meet the orientation requirements of the current production), the orientation of the wired junction box 1 is adjusted through the adjustment structure in the alignment device.

[0068] Adjustment solution one: The adjustment structure of the double jaw assembly 4 is a robotic arm 14. The double jaw assembly 4 is installed on the robotic arm 14. The method for adjusting the orientation of the wired junction box 1 is as follows:

[0069] First, open the first pair of jaws 4a to clamp and position the wired junction box 1 to prevent it from rotating due to its own weight; then drive the rotation of the robotic arm 14 to turn the wired junction box 1 upward in the required orientation; finally, drive the robotic arm 14 to descend to place the wired junction box 1, thus realizing the alignment adjustment of the wired junction box 1.

[0070] Adjustment solution two: The adjustment structure of the double jaw assembly 4 is a robotic arm 14. The double jaw assembly 4 is installed on the robotic arm 14. The method for adjusting the orientation of the wired junction box 1 is as follows:

[0071] First, grab the wired junction box 1 with the second pair of jaws 4b. At this time, the wired junction box 1 is in a freely swinging state; then slowly lower the wired junction box 1 so that its bottom touches a placement area (the blanking conveyor line 18); finally, move the upper or lower end of the wired junction box 1 according to the required orientation to make its required surface face upward, and continue to slowly lower it at the same time until the wired junction box 1 is placed in the required orientation.

[0072] Adjustment solution three: The adjustment structure of the double jaw assembly 4 is a robotic arm 14. The double jaw assembly 4 is installed on the robotic arm 14. The method for adjusting the orientation of the wired junction box 1 is as follows:

[0073] First, open the first pair of jaws 4a and close the second pair of jaws 4b at the same time. Control the robotic arm 14 to swing back and forth according to the direction of the visual inspection of the junction box. When the wired junction box 1 swings to the required side facing up, lower the robotic arm 14 so that the bottom of the wired junction box 1 touches the placement area; finally, continue to slowly descend so that the wired junction box 1 is placed in the required direction.

[0074] Adjustment scheme 4: The double-jaw assembly 4 is driven by a two-axis or three-axis linear drive mechanism including Z-axis movement, and the adjustment structure is a drive cylinder 15 fixed to the drive mechanism. The double-jaw assembly 4 is rotatably arranged on the drive mechanism, and the piston rod 15a of the drive cylinder 15 acts on one side of the double-jaw assembly 4 (such as Figure 13 、 14 ), the method for adjusting the direction of the wired junction box 1 is as follows:

[0075] First, the first pair of jaws 4a is opened to clamp the wired junction box 1 and position it to prevent it from rotating due to its own weight; then the cylinder 15 is driven to extend the piston rod 15a to support the side of the double-jaw assembly 4, so that the double-jaw assembly 4 and the positioned wired junction box 1 are tilted together, thereby making the required surface of the wired junction box 1 face upward; finally, the double-jaw assembly 4 is driven down to place the wired junction box 1 and release the first pair of jaws 4a, thereby completing the alignment adjustment of the wired junction box 1.

[0076] Alternatively, a rotary cylinder 16 (such as Figure 15 、 16 ), by fixing the cylinder body on the driving mechanism and fixing the rotating part 16a of the rotary cylinder 16 to one side of the double-jaw assembly 4, the double-jaw assembly 4 is tilted by rotating and driving it.

[0077] Alternatively, the double-claw assembly 4 can be rotated 180 degrees around the Z axis by a motor or a manipulator after the photo is taken, so that its orientation changes in mid-air, and then it can be placed directly. (Not shown)

[0079] S4. Visually inspect the wired junction box 1 on the unloading conveyor line 18 to check whether the wired junction box 1 is oriented as required or whether there are any defects.

By opening the first pair of jaws 4a, clamping and positioning of a wire 1a of the wired junction box 1 are achieved, and then picking up of the wired junction box 1 is realized.

[0083] In the double-jaw assembly 4, the two hook-shaped jaws of the second pair of jaws 4b are driven to have two states: open and closed; in the open state, the second pair of jaws 4b gives way and accepts the wire 1a of the wired junction box 1 picked up by the first pair of jaws 4a; in the closed state, the second pair of jaws 4b passes through the wire 1a of the wired junction box 1. At this time, the first pair of jaws 4a can be opened to release the positioning of the wired junction box 1, and the wired junction box 1 is grabbed by the second pair of jaws 4b by hanging on the second pair of jaws 4b through its wire 1a, so as to be photographed and identified by the first detection camera 8 whether its front and back orientations meet the processing requirements.
