[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] Figure 1 A structural schematic diagram of an embodiment of the present invention is shown. This embodiment relates to a solar module detection mechanism and system, which is used in the finished product inspection stage of solar modules to detect solar modules, including IV, voltage resistance, grounding and EL tests. The solar modules are tested by plug-in connectors, without the need for tooling turnover, improving test efficiency, realizing automated linkage actions, having a high degree of automation, improving test stability, and reducing labor costs.

[0039] A solar module detection mechanism, such as Figure 1-4 As shown, it includes a clamping device, a detection device 8 arranged opposite to the clamping device, and an adjusting device. The adjusting device is connected to the clamping device and the detection device 8 respectively, and adjusts the positions of the clamping device and the detection device 8 so that the position of the clamping device and the position of the detection device 8 correspond to the position of the connector 12 of the component, so that the clamping device clamps the connector 12 of the component and the detection device 8 detects the connector 12.

[0040] When the solar module detection mechanism is in use, during the detection process of the connector 12 of the module, when the module is transported to the mechanism, the adjusting device is activated to adjust the position of the clamping device so that the position of the clamping device corresponds to the position of the connector 12 of the module, and the connector 12 is positioned and clamped. The position of the detection device 8 is adjusted so that the position of the detection device 8 corresponds to the position of the connector 12, and the detection device 8 is plugged into the connector 12 to detect the module.

[0041] Specifically, the above-mentioned clamping device includes a first positioning clamping component 1 and a second positioning clamping component 2 that are relatively arranged, and a power drive component 7. The power drive component 7 is connected to the first positioning clamping component 1 and the second positioning clamping component 2 respectively to drive the first positioning clamping component 1 and the second positioning clamping component 2 to move. The second positioning clamping component 2 is arranged on the side of the first positioning clamping component 1 close to the detection device 8 to position and clamp the connector 12 of the component. The first positioning clamping component 1 is set up to roughly position the connector 12 and preliminarily determine the approximate position of the connector 12. The second positioning clamping component 2 is set up to accurately position the connector 12, clamp the connector 12, determine the accurate position of the connector 12, and keep the connector 12 motionless, so that the detection device 8 can be plugged into the connector 12 to detect the component.

[0042] In this embodiment, preferably, the first positioning clamping component 1 and the second positioning clamping component 2 are coaxially arranged, so that after the first positioning clamping component 1 preliminarily positions the connector 12, the second positioning clamping component 2 accurately positions and clamps the connector 12, so that the connector 12 is located on the same axis and will not cause damage to the connector 12.

[0043] Since the detection device 8 and the connector 12 are plugged into each other when detecting the component, a certain force will be applied to the connector 12. Therefore, in order to avoid the movement of the connector 12 during the detection process and cause inaccurate detection results, the first positioning clamping component 1 and the second positioning clamping component 2 are installed, and the second positioning clamping component 2 is arranged on the side of the first positioning clamping component 1 close to the detection device 8. The second clamping component accurately positions and clamps the connector 12 to prevent the connector 12 from moving during the detection process to ensure the accuracy of the detection results.

[0044] There is a certain distance between the first positioning and clamping component 1 and the second positioning and clamping component 2. The distance is selected and set according to the size of the connector 12 so that after the first positioning and clamping component 1 positions the connector 12, the second positioning and clamping component 2 positions and clamps the connector 12.

[0045] The above-mentioned first positioning clamping assembly 1 includes a first positioning member 100 and a second positioning member 101. The first positioning member 100 and the second positioning member 101 are both connected to the power drive assembly 7, driving the first positioning member 100 and the second positioning member 101 to move relative to each other. The first positioning member 100 and the second positioning member 101 can be relatively close to or far away from each other so as to position the connector 12. The first positioning member 100 and the second positioning member 101 are both plate-like structures. The first positioning member 100 is connected to the first connecting member 5, which is connected to the power drive assembly 7 so that the first positioning member 100 can be installed on the power drive assembly 7. Similarly, the second positioning member 101 is connected to the second connecting member 6, which is connected to the power drive assembly 7 so that the second positioning member 101 can be installed on the power drive assembly 7. Under the action of the power drive assembly 7, the first positioning member 100 and the second positioning member 101 are driven relatively close to or away from each other. In this embodiment, the first connecting member 5 and the second connecting member 6 are both plate-like structures. The first positioning member 100 is arranged to intersect with the first connecting member 5 and is located on the other side of the first connecting member 5 relative to the power drive component 7. Preferably, the first positioning member 100 is arranged perpendicular to the first connecting member 5; the second positioning member 101 is arranged to intersect with the second connecting member 6 and is located on the other side of the second connecting member 6 relative to the power drive component 7. Preferably, the second positioning member 101 is arranged perpendicular to the second connecting member 6.

[0046] In order to facilitate the positioning of the connector 12 when the first positioning member 100 and the second positioning member 101 are in contact, inclined surfaces are provided at corresponding positions on the opposite sides of the first positioning member 100 and the second positioning member 101. When the first positioning member 100 and the second positioning member 101 are relatively close and in contact, a V-shaped groove structure is constructed to position the connector 12 of the component. In this embodiment, the first positioning member 100 and the second positioning member 101 are located on the same straight line, and a slope is provided on the side of the first positioning member 100 facing the second positioning member 101. The slope is inclined from the other side of the first positioning member 100 opposite to the side connected to the first connecting member 5 toward the direction of the first connecting member 5 and the second positioning member 101 to form a slope structure. Correspondingly, a slope of the same structure is also provided at the corresponding position of the side of the second positioning member 101 facing the first positioning member 100. When the first positioning member 100 and the second positioning member 101 are relatively close and the relative sides are in contact, the slope on the first positioning member 100 and the slope on the second positioning member 101 construct a V-shaped groove structure. When the connector 12 is located in the V-shaped groove, the connector 12 is tangent to the two slopes to position the connector 12.

[0047] The above-mentioned second positioning and clamping assembly 2 includes a third positioning member 200 and a fourth positioning member 201. The third positioning member 200 and the fourth positioning member 201 are both connected to the power drive assembly 7 to drive the third positioning member 200 and the fourth positioning member 201 to move relative to each other. The third positioning member 200 and the fourth positioning member 201 can be relatively close to or away from each other to position and clamp the connector 12. The third positioning member 200 and the fourth positioning member 201 are both plate-shaped structures. The third positioning member 200 is connected to the first connecting member 5 and is located on the same side of the first connecting member 5 as the first positioning member 100. The third positioning member 200 and the first connecting member 5 are intersecting and preferably arranged vertically. The fourth positioning member 201 is connected to the second connecting member 6 and is located on the same side of the second connecting member 6 as the second positioning member 101. The fourth positioning member 201 and the second connecting member 6 are intersecting and preferably arranged vertically, so that the power drive assembly 7 can drive the third positioning member 200 and the fourth positioning member 201 to move relative to each other, and move closer to or away from each other.

[0048] The setting of the first connecting member 5 and the second connecting member 6 enables the power drive component 7 to simultaneously drive the first positioning member 100 and the third positioning member 200, and enables the power drive component 7 to simultaneously drive the second positioning member 101 and the fourth positioning member 201, so that the first positioning member 100 and the third positioning member 200 move simultaneously, and the second positioning member 101 and the fourth positioning member 201 move simultaneously.

[0049] Of course, the third positioning member 200 can be connected to the third connecting member, and the fourth positioning member 201 can be connected to the fourth connecting member. The third connecting member and the fourth connecting member are respectively connected to the power drive assembly 7 to drive the third connecting member and the fourth connecting member to move, and then drive the third positioning member 200 and the fourth positioning member 201 to move. In this case, the third positioning member 200 can move at the same time as the first positioning member 100, or at different times. The fourth positioning member 201 can move at the same time as the second positioning member 101, or at different times. The installation method of the third positioning member 200 and the fourth positioning member 201 is selected and set according to actual needs, and no specific requirements are made here.

[0050] Grooves are provided at corresponding positions on opposite sides of the third positioning member 200 and the fourth positioning member 201 . When the third positioning member 200 and the fourth positioning member 201 are relatively close to and in contact with each other, a receiving groove is formed to position the connector 12 of the assembly. The third positioning member 200 and the fourth positioning member 201 are located on the same straight line, and a groove is provided on the side of the third positioning member 200 facing the fourth positioning member 201, which is formed by the inward depression of the side. A groove is also provided at the corresponding position of the side of the fourth positioning member 201 facing the third positioning member 200, which is formed by the inward depression of the side. The cross-sectional shape of the groove is a curve, preferably an arc. When the third positioning member 200 and the fourth positioning member 201 are relatively close and in contact with the relative sides, the groove on the third positioning member 200 and the groove on the fourth positioning member 201 form a rough hole structure, and the connector 12 contacts the side wall of the groove. The third positioning member 200 and the fourth positioning member 201 position and clamp the connector 12, and position the connector 12 at the clamping device so that the detection device 8 can be plugged and connected to the connector 12.

[0051] In this embodiment, preferably, the first positioning member 100 is arranged in parallel with the third positioning member 200 , and the second positioning member 101 is arranged in parallel with the fourth positioning member 201 .

[0052] In order to buffer the force applied to the connector 12 when it is plugged into the detection device 8, and to prevent the connector 12 from being damaged due to excessive force, the second positioning clamping assembly 2 also includes a position adjustment assembly 3, which is respectively connected to the third positioning member 200 and the fourth positioning member 201, and adjusts the positions of the third positioning member 200 and the fourth positioning member 201, so that the position of the third positioning member 200 and the position of the fourth positioning member 201 can be moved according to the actual force conditions of the connector 12, thereby buffering the force applied to the connector 12.

[0053] The position adjustment assembly 3 includes a first guide member 300 connected to the third positioning member 200, a second guide member 301 connected to the fourth positioning member 201, and a reset member 4, wherein the third positioning member 200 can move relative to the first guide member 300, and the first guide member 300 guides the movement of the third positioning member 200. In this embodiment, the first guide member 300 is preferably a guide rail structure, and the first guide member 300 is mounted on the first connecting member 5. The third positioning member 200 is connected to the slider of the first guide member 300, and the third positioning member 200 can move relative to the first connecting member 5 through the first guide member 300.

[0054] The fourth positioning member 201 can move relative to the second guide member 301. The second guide member 301 guides the movement of the fourth positioning member 201. In this embodiment, the second guide member 301 is preferably a guide rail structure. The second guide member 301 is mounted on the second connecting member 6. The fourth positioning member 201 is connected to the slider of the second guide member 301. The fourth positioning member 201 can move relative to the second connecting member 6 through the second guide member 301.

[0055] One end of the reset member 4 is connected to the power drive assembly 7, and the other end is connected to the third positioning member 200 and the fourth positioning member 201, and the third positioning member 200 and the fourth positioning member 201 can move relative to this end, so that the third positioning member 200 and the fourth positioning member 201 can move with the reset member 4, and the reset member 4 will not interfere with the relative movement of the third positioning member 200 and the fourth positioning member 201. When the reset member 4 is set, it is set along the direction in which the first positioning clamping component 1 and the second positioning clamping component 2 are set in sequence. Through the movement of the reset member 4, the third positioning member 200 and the fourth positioning member 201 are driven to move relatively close to or away from the first positioning clamping component 1, so as to buffer the force applied to the connector 12 when the detection device 8 and the connector 12 are plugged in and connected, thereby avoiding damage to the connector 12 by the detection device 8. The reset member 4 can drive the third positioning member 200 and the fourth positioning member 201 to return to their original position after the connector 12 is detected, so as to position and clamp the connector 12 of the next component, so as to enable the detection device 8 to plug in the connector 12 of the next component and detect the next component.

[0056] The reset member 4 includes a support member and a moving member that are plug-connected. The moving member can reciprocate relative to the support member. An elastic member is mounted on the moving member, and the elastic member is in contact with or connected to the support member. The compression and extension of the elastic member are used to achieve reciprocating motion of the moving member relative to the support member. In the initial state, the elastic member is in a free state. When the moving member is subjected to pressure, the elastic member is compressed. When the pressure on the moving member disappears, the elastic member returns to its original position under the action of the restoring force, driving the moving member to return to its original position, thereby achieving the reset of the moving member. The support member is a tubular structure, one end of which is connected to the mounting plate, the mounting plate is fixedly mounted on the power drive assembly 7, and the other end is open. The moving member is a rod-shaped structure, one end of which is a stepped structure, having a small diameter section with a diameter smaller than the main body diameter, and the elastic member is sleeved on the small diameter section, and one end is in contact with the end face of the main body section of the moving member connected to the small diameter section. This end of the moving member and the elastic member extend into the support member, and the other end of the elastic member can be connected to the mounting plate, or in contact and fit, or not in contact, and can be selected and set according to actual needs. The elastic member moves as the moving member moves, so that the moving member is reset under the action of the elastic member.

Through holes are provided at corresponding positions of the first positioning member 100 and the second positioning member 101 to facilitate the passage of the reset member 4. The reset member 4 is located between the third positioning member 200 and the fourth positioning member 201, and is located below the third positioning member 200 and the fourth positioning member 201, so as not to interfere with the relative movement of the third positioning member 200 and the fourth positioning member 201. At the same time, when set, the reset member 4 has a gap with the first connecting member 5 and the second connecting member 6, and does not contact the first connecting member 5 and the second connecting member 6, so as not to interfere with the relative movement of the first connecting member 5 and the second connecting member 6.

It can be one power member, with the first positioning clamping assembly 1 and the second positioning clamping assembly 2 both connected to the power member, or two power members, with the first positioning clamping assembly 1 and the second positioning clamping assembly 2 respectively installed on one power member.

The cylinder is commercially available and should be selected based on actual needs; no specific requirements are set forth herein.

The image detection device 9 and the clamping device are arranged in sequence along the incoming direction of the module, both located on the same side of the module, and the distance between the image detection device 9 and the module is greater than the distance between the clamping device and the module, so that the image detection device 9 does not interfere with the clamping device's clamping action on the connector 12.

The solar module detection mechanism is connected to the lateral adjustment device, which is connected to the longitudinal adjustment device to adjust the position of the solar module detection mechanism. The lateral adjustment device and the longitudinal adjustment device are respectively connected to the control device of the mechanism to control the operation of the lateral adjustment device and the longitudinal adjustment device.

[0070] The solar module detection system also includes a gantry frame, which is arranged across the module conveyor line and is located at the detection position of the conveyor line. The gantry frame is made of a plurality of square tubes welded together. The transverse adjustment device is installed on the gantry frame, and the longitudinal adjustment device is installed on the transverse adjustment device. The transverse adjustment device drives the longitudinal adjustment device to move and adjusts the position of the longitudinal adjustment device in the transverse direction. The solar module detection mechanism is installed on the longitudinal adjustment device, and the longitudinal adjustment device drives the mechanism to move and adjusts the position of the mechanism in the longitudinal direction. Through the transverse adjustment device, the longitudinal adjustment device and the adjustment device of the mechanism, the position adjustment of the clamping device and the detection device 8 in three directions is realized (for ease of understanding, the transverse direction is set to the X-axis direction, the longitudinal direction is set to the Y-axis direction, and the direction of the adjustment device is set to the Z-axis direction).

[0071] A detection unit is composed of a transverse adjustment device, a longitudinal adjustment device and a solar module detection mechanism. In this embodiment, there are multiple detection units, which are arranged along the circumference of the solar module. Preferably, they are arranged on the upper and lower sides and left and right sides of the solar module. The solar detection system can also be provided with a control system, which is connected to each detection unit respectively. The control system can control the mechanisms in different positions to detect the modules according to the module type, so that the solar detection system can detect various types of solar modules.

[0072] When the solar detection system is in operation, the conveyor line transports the solar modules to the solar module detection system, and controls the solar modules to stop at the test position and perform centering through the blocking device and the centering device on the line. According to the type of solar module, the position of the connector 12 can be known, and the control system controls the corresponding detection unit to operate and detect the module.

[0073] The image detection device 9 is actuated to take a picture of the position of the connector 12 of the component to determine the specific position of the connector 12. The lateral adjustment device and the longitudinal adjustment device are actuated to adjust the position of the solar component detection mechanism and adjust the mechanism to the position of the connector 12. The adjustment device is actuated to bring the clamping device and the detection device 8 close to the connector 12 so that the connector 12 corresponds to the first positioning clamping component 1 and the second positioning clamping component 2. The power drive component 7 is actuated to bring the first positioning member 100 and the second positioning member 101 relatively close to each other so that the connector 12 is located in the V-shaped groove and the connector 12 is positioned. The third positioning member 200 and the fourth positioning member 201 are relatively actuated so that the connector 12 is located in the hole structure and the connector 12 is positioned and clamped.

[0074] The driving member 801 is actuated, so that the detection head 800 approaches the connector 12 and is plugged into the connector 12 to test the solar panel. The test items include IV, withstand voltage, grounding and EL. When the detection head 800 is plugged into the connector 12, the force applied to the connector 12 is greater than the force of the elastic member, which pushes the third positioning member 200 and the fourth positioning member 201 to move toward the first positioning clamping assembly 1, compressing the elastic member until the force on the connector 12 is balanced. After the test is completed, the driving member 801 is actuated, the detection head 800 is away from the connector 12, and the elastic member is reset under the action of the restoring force, pushing the third positioning member 200 and the fourth positioning member 201 to move and return to their original position. The power member is actuated, the third positioning member 200 and the fourth positioning member 201 are relatively separated, the first positioning member 100 and the second positioning member 101 are relatively separated, and the connector 12 is released. The adjusting device, the lateral adjusting device and the longitudinal adjusting device are actuated, so that the clamping device is away from the connector 12.

[0075] The blocking device and the centering device release the restrictions on the solar module, and the solar module is transported to the next workstation under the action of the conveyor line.

[0076] Repeat the above steps to test multiple solar panels.

[0077] Due to the adoption of the above technical solution, there is a clamping device, which has a first positioning clamping component and a second positioning clamping component. The first positioning clamping component roughly positions the connector, and the second positioning clamping component accurately positions and clamps the connector to keep the connector in the position of the clamping device; there is a detection device, which has a driving member and a detection head. The detection head can be plugged into the connector under the action of the driving member to achieve connection between the detection head and the connector and detect the component; there is an adjustment device, which can adjust the positions of the clamping device and the detection device so that the clamping device can quickly position and clamp the connector, and the detection device It can quickly connect with the connector; it has a reset part, which can buffer the excessive force when the connector and the detection device are connected during the connection process, so as to avoid damage to the connector; it has an image detection device, which can take the image of the connector on the component, and provide a mobile basis for the action of the adjustment device, the clamping device and the detection device; it realizes fully automated plug-in testing without the need for human intervention, and does not require the work and personnel of installing and removing test tooling, thereby reducing production costs and labor costs; it eliminates the test tooling and does not use tooling for testing, thereby reducing production costs; the detection head is directly connected to the connector, which reduces the resistance between the test probes, ensures the accuracy of the test results, and improves the component yield.

All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
