Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic modules, and in particular to automatic installation equipment and an installation method for an IV power-on test tool. Background Art

[0002] Photovoltaic IV curve testing is a crucial tool for analyzing the power generation performance of photovoltaic modules. Before leaving the factory, PV modules must undergo an IV curve test to determine their normal electrical performance and power output. During the IV test, the PV module must be connected to the test equipment using an IV power-on test fixture. The flexible connectors at both ends of the IV power-on test fixture are secured to the PV module frame. The connectors on the PV module's junction box are inserted into the sockets on the IV power-on test fixture. The positive and negative copper blocks in the IV power-on test fixture are then connected to the IV test equipment to perform IV curve and EL tests.

[0003] In the current photovoltaic module production line, a six-axis robot has been used to automatically install the IV power-on test tooling into the photovoltaic module. The specific installation process is as follows: the six-axis robot grabs the middle part of the tooling and moves it to the top of the photovoltaic module; the six-axis robot slightly tilts the tooling so that the card connector at one end first contacts the frame on one side of the photovoltaic module, and applies thrust to compress the spring on that side of the tooling to shorten the tooling as a whole; the six-axis robot straightens the tooling and removes the thrust, and the spring resets so that the card connector on the other side of the tooling is connected to the frame on the other side of the photovoltaic module; the six-axis robot grabs the positive and negative terminal blocks of the photovoltaic module junction box in turn and inserts them into the positive and negative terminal sockets of the IV power-on test tooling to complete the automatic installation of the IV power-on test tooling. The complete set of installation equipment includes a six-axis robot and a photovoltaic module conveying mechanism. The six-axis robot is installed on the side of the photovoltaic module conveying mechanism. The number of six-axis robots is one (it not only performs the clamping and placement of the tooling, but also performs the clamping and plugging of the positive and negative terminal heads one by one in sequence) or two (one performs the clamping and placement of the tooling, and simultaneously performs the clamping and plugging of one of the positive and negative terminal heads, and the other only performs the clamping and plugging of the other of the positive and negative terminal heads).

[0004] The automated installation method for the IV power-on test fixture in the aforementioned technical solution has the following drawbacks: 1. The six-axis robot's gripping of the center of the IV power-on test fixture and its tilted thrust can cause deformation, shortening its service life. 2. The six-axis robot must first place the IV power-on test fixture within the PV module before removing the terminal connector. Because the terminal connectors on the PV module are randomly positioned, the IV test fixture placed first may press against the connector, potentially preventing the six-axis robot from grasping the connector. 3. The six-axis robot is responsible for grabbing the IV power-on test tool, placing the IV power-on test tool, and plugging in the wires. These work processes must be carried out in sequence. The applicant found through testing that the installation time of this method is more than 16 seconds, which is relatively slow, resulting in the production capacity of the photovoltaic module production line being limited; 4. The cost of the six-axis robot is relatively high, the size is large, and the equipment cost is high, and it occupies a large space on the production line; 5. After repeated use of the IV power-on test tool, the tool will be more worn using the above method. When installed in the photovoltaic module, it will sag due to its own weight, resulting in the distance between the IV power-on test tool and the location of the terminal head becoming larger, and there is a risk that the terminal head cannot be accurately inserted into the socket of the IV power-on test tool.

[0005] Therefore, it is necessary to provide a new automatic installation device and installation method for IV power-on test tooling to solve the above problems. Summary of the Invention

[0006] In view of at least one of the above-mentioned technical problems, the present invention aims to provide an automatic installation device and an installation method for an IV power-on test tool.

[0007] The technical solution of the present invention is:

[0008] An object of the present invention is to provide an automatic installation device for an IV power-on test fixture, comprising:

[0009] The housing has a first installation space formed therein, and a set of opposite sides of the housing are respectively provided with an inlet and an outlet;

[0010] A conveying mechanism is provided in the housing, with its two ends in a conveying direction corresponding to the inlet and the outlet, respectively, for conveying and positioning photovoltaic modules in and out of the housing, with the conveying direction being a first direction;

[0011] a transfer line disposed within the housing and located on one side of the conveying mechanism, for receiving an IV power-on test tool to be installed and conveying it toward one side of the conveying mechanism in a second direction perpendicular to the first direction and positioning the tool at a loading position at an inner end of the transfer line;

[0012] a pick-and-place mechanism, which is disposed in the housing and above the conveying mechanism, and can be reciprocated and switched between above the tooling installation position on the photovoltaic module and the loading position along the second direction, and is used to clamp the IV power-on test tool to be installed at the loading position, and synchronously retract the clamping joints at both ends of the tooling, and move the tooling to above the photovoltaic module positioned on the conveying mechanism for wiring, and then install the tooling downward to the tooling installation position on the photovoltaic module;

[0013] A plug-in mechanism is arranged side by side with the pick-and-place mechanism in the casing, and can also move along the second direction. It is used to clamp the positive and negative terminal blocks on the photovoltaic module before the pick-and-place mechanism installs the IV power-on test tool on the photovoltaic module, and to perform the plug-in operation of connecting the positive and negative terminal blocks to the positive and negative sockets on the tool when the pick-and-place mechanism clamps the IV power-on test tool above the photovoltaic module.

[0014] Another object of the present invention is to provide an automatic installation method for an IV power-on test tool, comprising the following steps:

[0015] The CCD vision system automatically obtains the actual position of the positive and negative terminals on the photovoltaic module, and the plug-in mechanism adjusts the positions of the two sets of second clamping components according to the actual position and then clamps the two terminals respectively;

[0016] The two sets of first clamping assemblies of the pick-and-place mechanism grab the IV power-on test fixture from the loading position, and the two sets of second side pushing mechanisms retract the elastic card joints at both ends of the IV power-on test fixture inward and move it above the fixture installation position of the photovoltaic module;

[0017] The plug-in mechanism inserts the two terminal blocks into the two sockets of the IV power-on test tool at the same time;

[0018] The pick-and-place mechanism places the IV power-on test fixture into the photovoltaic module downward, and the elastic card connectors at both ends of the IV power-on test fixture are reset and respectively clamped on the frame of the photovoltaic module.

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] The present invention provides an automatic installation device for an IV power-on test fixture. When the fixture is clamped by a pick-and-place mechanism, force is applied evenly at both ends, preventing deformation. A wire insertion mechanism is used to clamp the positive and negative terminals on a photovoltaic module before the pick-and-place mechanism installs the IV power-on test fixture on the photovoltaic module. Once the pick-and-place mechanism has clamped the IV power-on test fixture above the photovoltaic module, the positive and negative terminals are connected to the positive and negative sockets on the fixture. Both the wire insertion mechanism and the pick-and-place mechanism are located inside the housing, eliminating the need for external space. This eliminates the need for a large footprint. Only openings are required on the side of the device for the loading mechanism, minimizing space on the production line. The wire insertion mechanism and the pick-and-place mechanism respectively handle the clamping and insertion of the terminals on the photovoltaic module, as well as the handling and loading of the IV power-on test fixture, resulting in more efficient installation. By inserting the terminals first and then installing the fixture, the terminals on the photovoltaic module are prevented from being pressed by the fixture, preventing obstruction and interference, and ensuring smoother and more accurate handling of the terminals. The terminal block is first plugged into the tooling and then installed on the photovoltaic module. The plugging of the terminal block is not affected by the wear of the tooling, which may cause the terminal block to be unable to be inserted into the socket. In summary, the installation device of the present invention occupies less site space, has higher installation efficiency, and the terminal block is grasped without obstruction and the plugging is not affected by the wear of the tooling.

DETAILED DESCRIPTION

[0036] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention. Example 1

[0037] An automatic installation device for an IV power-on test fixture is provided in an embodiment of the present invention. Figures 1 to 11 , mainly includes a casing 10, a conveying mechanism 20, a loading mechanism 60, a transfer line 50, a pick-and-place mechanism 40 and a wire insertion mechanism 30.

[0038] like Figure 1As shown, the photovoltaic assembly 90 of the embodiment of the present invention includes a glass panel 91 and an outer frame, two junction boxes provided on the glass panel 91, and junction heads (corresponding to positive and negative junction heads respectively) connected to the two junction boxes through wires. For the convenience of description and distinction, the two outer frames clamped by the IV power-on test fixture 80 are described as the first outer frame 921 and the second outer frame 922, the two junction boxes are described as the first junction box 931 and the second junction box 932 respectively, and the two junction heads are described as the first junction head 941 and the second junction head 942 respectively. The first and the second here are only for distinction and are not limited to a specific one of positive and negative. The IV power-on test fixture 80 has a socket that is plugged into the two wiring heads, as well as positive and negative electrode copper blocks and connectors at both ends for correspondingly connecting to the first outer frame 921 and the second outer frame 922 of the photovoltaic module 90. For ease of description and distinction, the two sockets are described as the first socket 811 and the second socket 812, the two electrode copper blocks are described as the first electrode copper block 821 and the second electrode copper block 822, and the two connectors are described as the first connector 831 and the second connector 832. Similarly, the first and second here are only for distinction and are not limited to a specific positive or negative. Specifically, the first wiring head 941 is connected to the first socket 811, the second wiring head 942 is connected to the second socket 812, the first connector 831 is connected to the inner side of the first outer frame 921, and the second connector 832 is connected to the inner side of the second outer frame 922.

[0039] For ease of description and distinction, in the embodiment of the present invention, the conveying direction of the conveying mechanism 20 is described as the first direction, and the conveying direction of the transfer line 50 and the moving direction of the pick-up and place mechanism 40 and the plug-in mechanism 30 are described as the second direction. The first direction and the second direction are perpendicular. Figure 2 As shown, the first direction is the X-axis direction in the figure, the second direction is the -Y-axis direction in the figure, and the vertical direction is the Z-axis direction in the figure.

[0040] like Figure 2 As shown, the housing 10 is a square frame having panels on four sides and a first installation space enclosed in the middle. A set of opposite sides is also the first direction or as shown in FIG. Figure 2 The front and rear sides of the housing 10 in the X-axis direction are provided with an inlet 11 and an outlet 12. Figure 2 The side in the Y-axis direction is also shown as Figure 2 The right side shown has an opening (not shown). Figure 2As shown, the conveying mechanism 20 is arranged in the casing 10 and the two ends of the conveying direction of the conveying mechanism 20 correspond to the feed port 11 and the discharge port 12 respectively. Specifically, the front end and the rear end of the conveying mechanism 20 extend outside the feed port 11 and the discharge port 12 respectively, and are used to convey the photovoltaic module 90 from the feed port 11 to the discharge port 12. Specifically, the conveying mechanism 20 conveys the photovoltaic module 90 from the feed port 11 into the casing 10 and positions it in the casing 10 to facilitate subsequent assembly and connection with the IV power-on test fixture 80 and after the photovoltaic module 90 is installed and connected with the IV power-on test fixture 80, it is conveyed from the discharge port 12 to the outside of the casing 10 for subsequent testing. That is to say, the automatic installation equipment in the embodiment of the present invention only completes the installation of the IV power-on test fixture 80 and the photovoltaic module 90 in the casing 10. The loading mechanism 60 is arranged at the opening of the casing 10. Specifically, as Figure 2 As shown, the customer can set a first direction from back to front on the outside of the opening of the housing 10. Figure 2 The tool conveyor line 70 is used to transport and load the IV power-on test tool 80 to be installed in the direction indicated by the middle arrow. The tool conveyor line 70 is set by the customer according to actual production. The specific structure is not described or limited here. It is not part of the automatic installation equipment of the embodiment of the present invention. The loading mechanism 60 is used to transfer the IV power-on test tool 80 transported on the tool conveyor line 70 to the housing 10, specifically to the transfer line 50. The transfer line 50 is set in the housing 10, and is used to receive the IV power-on test tool 80 to be installed transferred by the loading mechanism 60 and transport it along the second direction toward the side of the photovoltaic component 90 positioned on the conveying mechanism 20 and position it. Specifically, the inner end of the transfer line 50 is implemented as the position where the pick-up and place mechanism 40 grabs the IV power-on test tool 80, that is, the loading position (not marked). In order to save the time of adjustment after the pick-and-place mechanism 40 moves and improve production efficiency, the IV power-on test fixture 80 is positioned at the loading position. After positioning, the pick-and-place mechanism 40 does not need to be adjusted according to the position of the fixture of the transfer line 50, and can directly grab the IV power-on test fixture 80. That is to say, the positioning is set based on the premise that the pick-and-place mechanism 40 is translated in the reverse direction along the second direction to the loading position of the transfer line 50 without adjustment. The pick-and-place mechanism 40 is arranged in the housing 10 and is located above the conveying mechanism 20, and the pick-and-place mechanism 40 can move along the second direction. For the convenience of description, the position where the fixture is installed on the photovoltaic module 90, that is, Figure 1The position where the tooling is installed on the photovoltaic module 90 is described as the tooling installation position (not labeled). The pick-and-place mechanism 40 can reciprocate along the second direction between above the tooling installation position and above the loading position. The pick-and-place mechanism 40 is configured to grasp the IV power-on test tooling 80 to be installed at the loading position, simultaneously retract the clamping connectors at both ends of the tooling 80, and transfer it to the position above the photovoltaic module 90 positioned on the conveyor mechanism 20 for wiring before lowering it to the photovoltaic module 90. In this embodiment of the present invention, when grasping the tooling at the loading position, the clamping connectors at both ends of the photovoltaic module 90, namely the first clamping connector 831 and the second clamping connector 832, are simultaneously retracted inward. Therefore, when subsequently installing the tooling into the photovoltaic module 90, it only needs to be laid flat and released. This eliminates the need to tilt one end of the tooling and apply a thrust, as in the prior art six-axis robot, which can easily deform the stressed end and shorten the tooling's service life. In the automatic installation equipment of this embodiment of the present invention, the tooling is evenly stressed at both ends when grasped by the pick-and-place mechanism 40, making it less likely to deform. The plug-in mechanism 30 and the pick-up and placement mechanism 40 are arranged side by side in the casing 10, that is, the plug-in mechanism 30 is also located above the conveying mechanism 20, and the plug-in mechanism 30 can also move along the second direction. The plug-in mechanism 30 is used to clamp the positive and negative terminal blocks on the photovoltaic component 90 before the pick-up and placement mechanism 40 installs the IV power-on test tool 80 on the photovoltaic component 90, and to perform the plug-in operation of connecting the positive and negative terminal blocks to the positive and negative sockets on the tooling when the pick-up and placement mechanism 40 clamps the IV power-on test tool 80 above the photovoltaic component 90. That is to say, the automatic installation equipment of the IV power-on test fixture 80 in the embodiment of the present invention, based on the existing conveying mechanism for conveying photovoltaic modules 90, is provided with a wire insertion mechanism 30 that moves in a straight line direction for performing wire clamping and wire insertion operations respectively, and a pick-and-place mechanism 40 that performs the grabbing, loading and lowering installation of the IV power-on test fixture 80. Both mechanisms are inside the casing 10, and do not need to occupy the space outside the casing 10, that is, they do not need to occupy a large site. It is only necessary to make an opening on the side of the equipment and install the loading mechanism 60, which occupies a small space on the production line. Moreover, the wire insertion mechanism 30 and the pick-and-place mechanism 40 respectively perform the clamping and plugging of the terminal on the photovoltaic module 90 and the grabbing and loading of the IV power-on test fixture 80. Compared with the six-axis robot in the prior art that first performs the installation of the tooling and then performs the wire insertion operation, the installation efficiency of the automatic installation equipment of the embodiment of the present invention is higher. At the same time, the automatic installation equipment in the embodiment of the present invention first inserts the wires and then installs the tooling. Therefore, the wiring connector on the photovoltaic module 90 will not be pressed by the tooling, resulting in the connector being unable to be grasped. That is, the automatic installation equipment in the embodiment of the present invention will not be obstructed or interfered with, making the removal of the wiring connector smoother and more accurate. Furthermore, in the embodiment of the present invention, the wiring connector is first plugged into the tooling and then installed on the photovoltaic module 90. Therefore, the insertion of the wiring connector will not be affected by the wear of the tooling, which may cause the wiring connector to be unable to be inserted into the socket.

[0041] like Figure 3As shown, the conveying mechanism 20 includes a belt line 21 and a correction mechanism. The side of the inlet 11 is the front side, and the side of the outlet 12 is the rear side. In this embodiment of the present invention, the correction mechanism includes a forward pushing mechanism 22 located on the side of the belt line 21 near the inlet 11, i.e., the front side; a blocking mechanism 23 located on the side of the belt line 21 near the outlet 12, i.e., the rear side; and third side pushing mechanisms 24 symmetrically located on both sides of the belt line 21. The blocking mechanism 23 is fixed to the side of the belt line 21, the forward pushing mechanism 22 is arranged in the middle of the belt line 21 so as to be movable in a first direction, i.e., the front-to-back direction; and the two third side pushing mechanisms 24 are arranged on both sides of the belt line 21 so as to be relatively movable in a second direction. In this embodiment of the present invention, there are illustratively four belt lines 21, and the four belt lines 21 are connected to a drive motor (not shown) on one side via a drive wheel (not shown) and a connecting rod (not shown) on the rear side to achieve synchronous transmission. Two blocking mechanisms 23 are respectively disposed on the inner side of the rear ends of the two belt lines 21 on either side, two third side-pushing mechanisms 24 are respectively disposed on the outer side of the two belt lines 21 on either side, and a forward-pushing mechanism 22 is disposed in the middle of the front ends of the two middle belt lines 21 and can push the photovoltaic assembly 90 from front to rear along a first direction. The blocking mechanism 23 is used to block and position the rear end of the photovoltaic assembly 90, the forward-pushing mechanism 22 is used to move rearward to abut against the front end of the photovoltaic assembly 90 to block and position the front end of the photovoltaic assembly 90, and the two third side-pushing mechanisms 24 respectively block and position the two side edges of the photovoltaic assembly 90. In this embodiment of the present invention, the blocking mechanism 23 is fixed in the horizontal plane, i.e., it is immovable in the first and second directions and can be raised and lowered in the vertical direction, while the third side-pushing mechanism 24 is movable in the second direction but cannot be moved in either the first or vertical direction, while the forward-pushing mechanism 22 is movable in the first direction and can be raised and lowered in the vertical direction but cannot be moved in the second direction. Preferably, the movement of the forward pushing mechanism 22, the blocking mechanism 23 and the third side pushing mechanism 24 is driven by a cylinder, and the specific structure is not described or limited. The cylinder-driven structure is simple and low-cost. It should be noted that the forward pushing mechanism 22, the blocking mechanism 23 and the third side pushing mechanism 24 are all provided with positioning rollers 25 for abutting against the corresponding side edges of the photovoltaic assembly 90 to achieve the positioning of the photovoltaic assembly 90. In the embodiment of the present invention, preferably, in order to facilitate the subsequent transportation of the photovoltaic assembly 90 out of the shell, the positioning of the photovoltaic assembly 90 on the conveying mechanism 20 is biased toward the side of the discharge port 12, that is, the positioning of the photovoltaic assembly 90 is positioned backward. The number of positioning rollers on each blocking mechanism 23 is preferably one, the number of positioning rollers on the forward pushing mechanism 22 is two and symmetrically arranged, and the number of positioning rollers 25 on each third side pushing mechanism 24 is also two and symmetrically arranged.In addition, the positioning roller 25 on the front pushing mechanism 22 and the positioning roller 25 on the blocking mechanism 23 are both lifting rollers that can be raised and lowered in the vertical direction, such as by relying on cylinder drive for lifting. The structure is simple and the cost is low. The purpose of setting it to a lifting type is to avoid obstruction and interference of the photovoltaic component 90 when it enters the positioning position and is transported out of the casing 10 from the positioning position. The positioning rollers 25 on the two third side pushing mechanisms 24 do not interfere with the conveying direction of the photovoltaic component 90, so there is no need to set it to be liftable.

[0042] like Figure 4 As shown, the loading mechanism 60 includes a bracket 61, a first linear motion module 62, and a loading assembly 63. The bracket 61 comprises a horizontally arranged horizontal frame connected to the frame body (not shown) within the housing 10 and two diagonal braces. Two parallel, spaced first linear motion modules 62 are provided on the horizontal frame and extend in a second direction, i.e., the Y direction in the figure. The first linear motion modules 62 may, for example, include a module comprising a gear rack and a linear guide, a module comprising a synchronous belt and a linear guide, or other modules familiar to those skilled in the art. For ease of distinction, the linear guides herein are described as first linear guides. The loading assembly 63 is slidably connected to the two first linear motion modules 62, and is not specifically described or limited. The specific structure of the loading assembly 63 is not specifically described or limited. Optionally, the loading assembly 63 includes a clamping component and a lifting drive component (such as a conventional lifting cylinder) that slidably cooperates with the first linear motion module 62 and is used to drive the clamping component to rise and fall in a vertical direction. The lifting drive component can be optionally slidably connected to the first linear motion module 62 through a roller or a slider, which will not be described or limited in detail. The outer end of the transfer line 50 is outside the opening and fixed to the bracket 61, and the loading assembly 63 can be reciprocated and switched between the side of the bracket 61 close to the tooling conveyor line 70 and the upper part of the outer end of the transfer line 50. Because the tooling conveyor line 70 may not be in the same height as the transfer line 50, a lifting loading assembly 63 is used so that it can be adjusted according to the height of the tooling conveyor line 70 and the transfer line 50. For the clamping component, the existing conventional cylinder-driven clamp, also known as the pneumatic clamp, can be selected. The specific structure will not be described or limited, and it is easy for those skilled in the art to know and implement it.

[0043] like Figure 4 As shown, the transfer line 50 of the embodiment of the present invention is consistent with the belt line 21 of the conveying mechanism 20 in structure and will not be described again. In order to realize the positioning of the IV power-on test tool 80 at the loading position, the purpose of positioning is to make the tool straight, that is, the two ends face the first direction. A stop mechanism 51 is provided at the inner end of the transfer line 50 and positioning components are provided on both sides of the transfer line 50. As for the stop mechanism 51, it is an L-shaped stopper driven by an existing conventional cylinder to rise and fall in the vertical direction. At the inner end of the L-shaped stopper, that is, as shown in FIG. Figure 4 The left end shown is provided with an in-place detection device 511 for detecting whether the photovoltaic component 90 is in place, such as an existing conventional photoelectric sensor. As for the positioning component, in the embodiment of the present invention, it is preferred that one side is fixed and the other side is movable, that is, the tooling is positioned sideways at the loading position. In this way, it is only necessary to pre-fix the fixed side in accordance with the position when the pick-up and placement mechanism 40 moves to the loading position without adjusting the state. Then, each time, it is only necessary to adjust the tooling that is deflected on the transfer line 50 through the movable positioning component, and the structure is simpler. Specifically, the positioning component includes a device provided on one side of the transfer line 50, that is, Figure 4 The fixed baffle 53 on the rear side and a baffle 53 on the other side of the transfer line 50 are shown. Figure 4 The movable first side pushing mechanism 52 on the front side is shown. As for the first side pushing mechanism 52, it is a push plate that slides along the slide rail in the X direction and is driven by a cylinder. It has the same structure as the third side pushing mechanism 24 mentioned above (the difference is that there is no positioning roller, but a push plate). The specific structure will not be described or limited. It is easy for those skilled in the art to know and implement it. In the embodiment of the present invention, the in-place detection device 511 is electrically connected to the first side pushing mechanism 52, specifically the driving cylinder that drives the push plate of the first side pushing mechanism 52 to move. When the in-place detection device 511 detects that the tooling is in place, the driving cylinder drives the push plate along Figure 4The -X direction movement shown in the figure is that the side where the baffle 53 is located is brought together to press against one end of the tooling and the other end of the tooling is pressed against the baffle 53, thereby realizing the positioning of the tooling at the loading position. As an alternative embodiment, both sides can be movable or fixed. When both sides are movable, that is, two first side pushing mechanisms 52 are set. In order to facilitate the two first side pushing mechanisms 52 to move and adjust when the pick-and-place mechanism 40 moves to the loading position at the inner end of the transfer line 50, it is also necessary to add a photoelectric sensor to detect the position of the two sets of first clamps 441 and the second side pushing mechanism 442 after the pick-and-place mechanism 40 reaches the loading position so that the two first side pushing mechanisms 52 can perform corresponding pushing according to the detected position information without moving after positioning. In this case, the positions of the two sets of first clamps 441 and the second side pushing mechanism 442 on the first beam 14 are fixed, which is determined by the length of the tooling and the clamping position. The structure is relatively more complicated. When both sides are fixed, that is, two baffles 53 are set, the distance between the two baffles 53 should be the same as or slightly longer than the length of the tooling. The two baffles 53 are set according to the two groups of first clamps 441 and the second side pushing mechanism 442 when the pick-up and placement mechanism 40 reaches the loading position. In this case, the positions of the two groups of first clamps 441 and the second side pushing mechanism 442 on the first beam 14 are also fixed. However, because the baffles on both sides are fixed and the space in the middle is limited, the loading mechanism 60 needs to be more careful when placing the tooling on the transfer line 50, and the tooling is more likely to be bumped when being transported on the transfer line 50.

[0044] The inner sides of the two inner side walls of the housing 10 corresponding to the first direction, namely the front and rear inner side walls, are respectively provided with Figure 5 The two inner beams 13 extending in the Y direction shown in FIG and the sliding cross-beams 13 extending in the first direction as shown in FIG. Figure 5 As shown, the first crossbeam 14 and the second crossbeam 15 are arranged in a relative spaced relationship and extend in the X-axis direction. The two inner crossbeams 13 are respectively provided with a second linear guide rail 131 extending in the second direction. The two ends of the first crossbeam 14 and the second crossbeam 15 are respectively slidably connected to the second linear guide rails 131 on the two inner crossbeams 13. The pick-up and drop mechanism 40 and the wire insertion mechanism 30 are respectively provided on the first crossbeam 14 and the second crossbeam 15. Preferably, the power for the first crossbeam 14 and the second crossbeam 15 to move in the second direction is a servo reduction motor 16. Specifically, as shown in FIG. Figure 5As shown, synchronous pulley assemblies 18 are provided at both ends of the first crossbeam 14 and the second crossbeam 15. Taking the first crossbeam 14 as an example, a servo reduction motor 16 is disposed in the middle of the first crossbeam 14. The output end of the servo reduction motor 16 is connected to the two synchronous pulley assemblies 18 at both ends of the first crossbeam 14 via two shafts 17 extending in the first direction (the two shafts 17 are coaxially connected in a front-to-rear manner along the first direction), forming a linkage assembly. A belt 19 is provided on each of the two inner crossbeams 13, extending in the second direction and connected to the corresponding synchronous pulley assembly 18. In an exemplary embodiment of the present invention, the synchronous pulley assembly 18 at each end includes three synchronous pulleys, which are spaced apart in sequence along the second direction, with the middle synchronous pulley positioned higher than the two synchronous pulleys on either side. The middle synchronous pulley is connected to the servo reduction motor 16 via the shaft 17, and the two synchronous pulleys on either side are connected to the middle synchronous pulley via a belt 19. Specifically, the belt 19 passes through the three synchronous pulleys sequentially along the transmission direction, i.e., the second direction. Adopting this structure as the driving structure for the movement of the first crossbeam 14 and the second crossbeam 15 along the second direction is cheaper and has lower cost.

[0045] In the embodiment of the present invention, the first beam 14 is close to the side where the opening is located, and the second beam 15 is far away from the side where the opening is located, that is, the picking and placing mechanism 40 is arranged on the first beam 14, and the wire insertion mechanism 30 is arranged on the second beam 15.

[0046] like Figure 6 As shown, the pick-and-place mechanism 40 includes a vertical plate 41, a third linear guide 42, a mounting frame 43 and a first clamping assembly 44. The vertical plate 41 is arranged on the side of the first beam 14 facing the second beam 15 and extends in the vertical direction. The third linear guide 42 is arranged on the side of the vertical plate 41 facing the second beam 15 and extends in the vertical direction. The mounting frame 43 is slidably arranged on the third linear guide 42 and extends in the first direction, that is, the X-axis direction shown in the figure. It should be noted that a slide and a slider (not shown) are further provided between the mounting frame 43 and the third linear guide 42. The first clamping assembly 44 includes two groups of first clamps 441 and two groups of second side pushing mechanisms 442. The two groups of first clamps 441 are arranged relative to each other and are arranged in the middle of the two groups of second side pushing mechanisms 442 that are relative to each other and are arranged at intervals. In the two sets of first clamps 441 and two sets of second side pushing mechanisms 442 in the embodiment of the present invention, at least one set of first clamps 441 and one set of second side pushing mechanisms 442 can be moved along the first direction relative to the mounting frame 43. Preferably, in order to reduce the difficulty of adjustment, the present invention adopts one set of first clamps 441 and one set of second side pushing mechanisms 442 to be fixed, and the other set of first clamps 441 and second side pushing mechanisms 442 to be movable. Further preferably, the side close to the feed port 11, i.e., Figure 6The rear set of first clamps 441 and second side pushing mechanisms 442 shown can slide relative to the mounting frame 43. This arrangement is to correspond to the rearward positioning of the photovoltaic assembly 90 described above. Figure 7 As shown, the bottom of the mounting frame 43 is provided with a first direction, that is, Figure 6 The fourth linear guide 45 extends in the X-axis direction, the first clamp 441 includes a first clamping jaw component and an adjustment component 46, the second side-pushing mechanism 442 includes a side-pushing assembly and an adjustment component 46, and the adjustment components 46 of the first clamp 441 and the second side-pushing mechanism 442 have the same structure. The first clamp 441 and the second side-pushing assembly are both fixed to the fourth linear guide 45 by the adjustment component 46. For the first clamping jaw component, an existing conventional pneumatic clamp can be selected, and the specific structure is not described or limited. For the side-pushing assembly, it is also a cylinder-driven push plate type structure, similar to the structure of the first side-pushing mechanism 52, and the specific structure is not described or limited. The two sets of first clamps 441 in the embodiment of the present invention are used to clamp the two electrode copper blocks on the tooling, and the two second side-pushing mechanisms 442 are used to compress the clamping joints at both ends of the tooling inward, so that the two clamping joints shrink inward and become shorter, so that they can be placed flat on the photovoltaic component 90 and after the thrust is removed, the clamping joints will automatically extend outward and reset and automatically snap into the first outer frame 921 and the second outer frame 922 of the photovoltaic component 90. As for the adjustment component 46, the adjustment component 46 of the first clamp 441 is used as an example in the embodiment of the present invention. The adjustment component 46 of the second side-pushing mechanism 442 has the same structure and will not be repeated. Specifically, as Figure 8As shown, the adjustment assembly 46 includes a fixed block 461, two clamping blocks 462, and an adjustment rod 463. The top of the fixed block 461 has two protrusions 4611, with a gap between the two protrusions 4611 to define a second installation space. The first clamping jaw component and the side thrust assembly are respectively fixed to the bottom of the corresponding fixed block 461 of the adjustment assembly 46. In other words, the fixed block 461 is actually a U-shaped plate with a groove in the middle of the top. The shape of the two clamping blocks 462 matches the shape of the slide grooves (not shown) on both sides of the fourth linear guide 45. The two clamping blocks 462 are respectively disposed inside the two protrusions 4611 and slidably engage with the fourth linear guide 45. An adjustment rod 463 is rotatably provided on one of the protrusions 4611. When the inner end of the adjustment rod 463 rotates inward, it abuts against the side of the block 462 on the side where the protrusion 4611 is located, so that the block 462 is only abutted against the slide groove on the fourth linear guide 45, thereby achieving the fixation of the first clamping jaw component or the side push assembly to the fourth linear guide 45. With such a design, the distance between the two groups of first clamps 441 and the two groups of second side push mechanisms 442 can be adjusted according to the specific length of the tooling and the distance between the two electrode copper blocks to improve the adaptability of the pick-and-place mechanism 40. As for the adjustment rod 463, it can be an existing conventional manual adjustment rod or an existing conventional electric adjustment rod. The specific structure is not described or limited, and it is easy for those skilled in the art to know and implement it. Preferably, it is an electric adjustment rod.

[0047] like Figure 9 As shown, the insertion mechanism 30 includes a fifth linear guide 31 and two groups of second clamping assemblies. The two groups of second clamping assemblies are driven by a driving mechanism 33 to move along the fifth linear guide 31, or each group is independently driven by a driving mechanism 33 to move along the fifth linear guide 31. The fifth linear guide 31 is arranged on the side of the second beam 15 facing the first beam 14 and along the first direction, that is, as shown in FIG. Figure 9 The two sets of second clamping components are slidably arranged on the fifth linear guide rail 31 in a relative and spaced manner. Figure 9 As shown, it includes a second clamp 32. Preferably, in this embodiment, the two sets of second clamping assemblies are driven by the same driving mechanism 33 to move toward or away from each other. As for the driving mechanism 33, it is an existing conventional servo reduction motor, which can be selected to be similar to the driving structure for the first beam 14 and the second beam 15 to move along the second direction, that is, the structure of the synchronous pulley assembly and the servo reduction motor, which will not be repeated here. For the second clamp 32, specifically, as Figure 10As shown, the second clamp 32 includes a fixed plate 321, a lifting cylinder 322, a rotating motor 323, a second clamping jaw component 324, a CCD vision system 325, and a light source 326. The fixed plate 321 is slidably connected to the fifth linear guide 31 through a structure such as a slider or a slide rail (not shown). The lifting cylinder 322 is provided on the side of the fixed plate 321 and the driving end of the lifting cylinder 322 is downward, that is, the driving end of the lifting cylinder 322 is as shown. Figure 10 The bottom end of the lifting cylinder 322 is shown, and the driving end of the lifting cylinder 322 can be extended and retracted in the vertical direction. The rotating motor 323 is provided on the driving end of the lifting cylinder 322 and the driving end of the rotating motor 323 faces downward and can rotate horizontally around the vertical line. The second clamping claw component 324 is provided on the driving end of the rotating motor 323. Figure 10 The bottom end of the rotating motor 323 is shown. The second clamping member 324 can be a conventional cylinder-driven clamping member. The specific structure is not described or limited in detail. The CCD vision system 325 is disposed on the fixed plate 321, located on one side of the lifting cylinder 322 and above the second clamping member 324. It is used to obtain the actual position of the positive and negative terminal blocks on the photovoltaic module 90, namely the first terminal block 941 and the second terminal block 942. The light source 326 is disposed on the fixed plate 321 and below the CCD vision system 325. The CCD vision system 325 is electrically connected to the drive mechanism 33, the lifting cylinder 322, and the second clamping jaw component 324. After the CCD vision system 325 detects the actual position of the first terminal 941 and the second terminal 942, it will feed back the position signal to the drive mechanism 33, the lifting cylinder 322, and the second clamping jaw component 324. After receiving the actual position information, the drive mechanism 33 and the lifting cylinder 322 will make corresponding feedback to drive the second clamping jaw component 324 to perform horizontal movement, lifting, rotation, and other actions to achieve position adjustment until the second clamping jaw component 324 reaches the position of the corresponding terminal and then clamps the terminal. The specific adjustment process and principle are not described or limited in detail. They are not the invention points of this application. They are existing conventional technologies that are known to those skilled in the art and can be easily implemented.

[0048] The head of the terminal block on the photovoltaic module 90 may be tilted. If the second clamping jaw 324 directly clamps the head of the terminal block, the terminal block may be in a skewed state, which will be detrimental to the subsequent wiring operation. Therefore, it is necessary to press the terminal block against the glass surface before the second clamping jaw 324 closes and clamps the terminal block. In order to achieve the above purpose, the embodiment of the present invention is as follows: a pressing mechanism 327 is further provided on the side of the second clamping jaw 324. Specifically, as Figure 11As shown, the pressing mechanism 327 includes a limit plate 3271, a sixth linear guide 3273, a pressure block 3274, an elastic member 3276, and a limit member (not shown). The limit plate 3271 is mounted on the side of the second clamping jaw member 324. The side of the limit plate 3271 facing the second clamping jaw member 324 has a recessed channel (not shown) extending in the vertical direction. The inner wall of the channel is provided with a fixed slider 3272. The sixth linear guide 3273 is arranged near the side of the second clamping jaw member 324 but is not connected or fixed thereto. The sixth linear guide 3273 and the slider 3272 are slidably engaged together. The pressure block 3274 is connected to the second clamping jaw member 324 through an L-shaped connecting block 3275. Mounted at the bottom end of the sixth linear guide rail 3273, the pressure block 3274 is positioned between the two jaws of the second clamping member 324. An elastic member 3276 is vertically disposed and comprises a guide rod and a spring sleeved thereon. The top of the guide rod extends upward through the limit plate 3271, and a retaining member (e.g., a nut) is provided on the top of the guide rod to prevent it from falling off the limit plate 3271 due to its own gravity. The spring is located at the bottom of the limit plate 3271, and the bottom end of the guide rod is connected to the side of the connecting block 3275. When the pressure block 3274 is in a free state, not pressed against the terminal, it tends to move downward under the action of gravity, with the bottom end of the pressure block 3274 being approximately flush with the bottom ends of the two second clamping members 324. Preferably, the bottom end of the pressure block 3274 is slightly lower than the bottom ends of the two second clamping members 324, so that the terminal first contacts the pressure block 3274. When the pressure block 3274 is pressed against the head of the terminal block, the pressure block 3274 will move upward, causing the spring to be compressed and deformed by the upward extrusion force. This compression deformation applies a downward reaction force to the pressure block 3274, so that the head of the terminal block is pressed flat against the glass panel 91 of the photovoltaic module 90 by the pressure block 3274. In this way, when the second clamping jaw component 324 clamps the head of the terminal block, the head of the terminal block will no longer be skewed, and the connection between the terminal block and the socket will be more convenient and smooth. Preferably, when the pressure block 3274 is in a free state without being pressed against the terminal block, the limiter presses against the top surface of the limit plate 3271 and the spring is in a compressed state, thereby applying a downward force to the pressure block 3274, so that the pressure block 3274 has sufficient downward pressure when it contacts the head of the terminal block.

[0049] As an alternative embodiment, in the automatic installation equipment of the embodiment of the present invention, the housing 10 may not be provided with an opening, and the loading mechanism 60 moves above the housing 10 to enable the tooling to enter and exit the housing 10.

[0050] As another alternative embodiment, the automatic installation equipment of the embodiment of the present invention may also not include the loading mechanism 60, but instead directly feed the tooling into the casing 10 through the opening on one side of the casing 10 through the tooling conveyor line 70 of the client.

[0051] As another alternative embodiment, the CCD vision system 325 may not be disposed on the fixed plate 321 , but a third beam (not shown) may be disposed between the first beam 14 and the second beam 15 , and the CCD vision system 325 may be disposed on the third beam.

[0052] In summary, the pick-and-place mechanism 40 in this embodiment of the present invention has three degrees of freedom (X, Y, and Z axes), while the wire insertion mechanism 30 has four degrees of freedom (X, Y, Z, and R axes). Replacing conventional six-DOF robots with a three-DOF pick-and-place mechanism 40 and a four-DOF wire insertion mechanism 30 reduces space requirements, improves installation efficiency, and allows for unobstructed access to wire terminals, while also ensuring that insertion is unaffected by tooling wear. Example 2

[0053] This embodiment provides an automatic installation device for an IV power-on test fixture. This embodiment differs from the first embodiment in that the second crossbars 15 are two in number, the two crossbars 15 being disconnected, that is, independent, and the two sets of second clamping assemblies are each disposed on a second crossbar 15. The two sets of second clamping assemblies move independently, that is, are not constrained by each other. In other words, whereas the two sets of second clamping assemblies in the first embodiment move synchronously along the second direction, the two sets of second clamping assemblies in the present embodiment move independently along the second direction. With this design, because the positions of the two terminal blocks on the glass panel 91 are random, that is, not necessarily on the same horizontal line, the design of the first embodiment would prevent the two sets of second clamping assemblies from simultaneously clamping the two terminal blocks. Instead, the clamping may need to be performed in stages, first grasping the terminal block closer to the photovoltaic module 90 and then the terminal block farther away from the photovoltaic module 90. However, with the design of the present embodiment, the two second clamping assemblies move independently and are not affected by each other, thereby achieving synchronous clamping of the two terminal blocks, resulting in higher production efficiency. The applicant's research and testing have found that the design of this embodiment can save more than 1 second in production efficiency. This means that when performing batch installation, the time savings will reach an order of magnitude, which means that efficiency will be greatly improved. Specifically, referring to Figures 12 and 13, the two inner crossbeams 13 and the second linear guides 131 and belt 19 thereon are partially shown. The connection method between the two second crossbeams 15 and the two second linear guides 131 and belt 19 is the same as in Example 1 and will not be repeated here. The difference is that in this embodiment, each second crossbeam 15 must be equipped with a servo reduction motor to independently drive the corresponding second crossbeam 15 to move in the second direction. Because the two second crossbeams 15 are disconnected, in order to ensure the stability of the second crossbeams 15, a sliding support structure should be added to the bottom of the end of the two second crossbeams 15 that is close to each other. Specifically, the sliding support structure includes a support frame 100 fixedly connected to the housing 10 and a seventh linear guide 101 provided on the support frame 100 and extending in the second direction. The two second crossbeams 15 respectively slide in conjunction with the corresponding seventh linear guide 101. For the support frame 100, in order to improve the stability and reliability of the support frame 100, Figure 12 The left end side is provided with a diagonal brace 102. However, the diagonal brace 102 of this structure will interfere with the corresponding second crossbeam 15 and the plug-in mechanism 30 thereon, which will affect the movement of the second crossbeam 15. Preferably, as Figure 13 As shown, the diagonal brace 102 is arranged at the bottom of the support frame 100. Figure 13This is a top view, so the diagonal brace 102 is obscured by the support frame 100 and is not shown. This design prevents the diagonal brace 102 from interfering with the second crossbeam 15 and the wiring mechanism 30 thereon, and thus does not affect the travel of the second crossbeam 15. However, this solution has a drawback in that it is more expensive than in Example 1. Example 3

[0054] An embodiment of the present invention provides an automatic installation method for an IV power-on test tool, comprising the following steps:

[0055] The CCD vision system 325 automatically obtains the actual position of the positive and negative terminals on the photovoltaic module 90, and the wiring mechanism 30 adjusts the positions of the two sets of second clamping components according to the actual position and then clamps the two terminals respectively;

[0056] The two sets of first clamping assemblies 44 of the pick-and-place mechanism 40 grab the IV power-on test fixture 80 from the loading position, and the two sets of second side pushing mechanisms 442 retract the elastic clamping joints at both ends of the IV power-on test fixture 80 inward and move it to above the fixture installation position of the photovoltaic module 90;

[0057] The plug-in mechanism 30 inserts the two connection heads into the two sockets of the IV power-on test fixture 80 at the same time;

[0058] The pick-and-place mechanism 40 lowers the IV power-on test fixture 80 into the photovoltaic module 90. The elastic connectors at both ends of the IV power-on test fixture 80 snap back into place on the frame. It should be noted that in the above method steps, the clamping and inserting actions of the wire insertion mechanism 30 and the clamping and loading actions of the pick-and-place mechanism 40 are not sequential. Preferably, to further improve production efficiency, the clamping and inserting actions of the wire insertion mechanism 30 and the clamping and loading actions of the pick-and-place mechanism 40 are performed simultaneously.

[0059] According to some preferred embodiments of the present invention, the following steps are further included:

[0060] The photovoltaic assembly 90 is transported by the transport mechanism 20 to the housing 10 and positioned; this step can be performed before or after the clamping and inserting of the wire by the wire insertion mechanism 30 and the clamping and loading of the tooling by the pick-and-place mechanism 40, or can be performed simultaneously.

[0061] The transport mechanism 20 transports the connected and installed IV power-on test fixture 80 and photovoltaic module 90 out of the housing 10 for connection to the IV test instrument and subsequent testing. This step is the final step. The subsequent testing is not the subject of this invention and is prior art, so it will not be described here. Those skilled in the art will understand this.

[0062] According to some preferred embodiments of the present invention, the following steps are further included:

[0063] The loading mechanism 60 grabs the IV power-on test jig 80 to be installed from the jig conveyor line 70 and transfers it to the transfer line 50. The IV power-on test jig 80 is positioned after reaching the loading position at the inner end of the transfer line 50. This step occurs before the gripping jig of the pick-and-place mechanism 40 is loaded above the jig installation position of the photovoltaic module 90.

[0064] In the embodiment of the present invention, the pick-and-place mechanism 40 simultaneously retracts the clamping joints at both ends of the photovoltaic module 90, namely the first clamping joint 831 and the second clamping joint 832, inward when grabbing at the loading position. Therefore, when the subsequent tooling is installed in the photovoltaic module 90, it only needs to be laid flat downwards, without the need to tilt one end and apply thrust as in the prior art, which makes the stressed end more likely to deform and shorten the service life of the tooling. In the automatic installation equipment of the embodiment of the present invention, the forces at both ends of the tooling are evenly distributed and not prone to deformation. Moreover, the plug-in mechanism 30 and the pick-and-place mechanism 40 respectively perform the clamping of the terminal on the photovoltaic module 90, the plug-in of the wires, and the grabbing and loading of the IV power-on test tooling 80. Compared with the six-axis robot in the prior art that first performs the installation of the tooling and then performs the plug-in operation, the automatic installation equipment of the embodiment of the present invention has a higher installation efficiency. According to the applicant's test verification, compared with the six-axis robot installation method in the prior art, the installation method of the embodiment of the present invention is improved by more than 1s. When batch production and the production quantity are larger, the efficiency will be further improved. At the same time, the automatic installation equipment in the embodiment of the present invention first inserts the wires and then installs the tooling. The wiring connector on the photovoltaic module 90 will not be pressed by the tooling, resulting in the problem of being unable to grasp the wiring connector. In other words, the automatic installation equipment in the embodiment of the present invention will not be blocked or interfered with, and the wiring connector can be taken more smoothly and accurately. Moreover, in the embodiment of the present invention, the wiring connector is first plugged into the tooling and then installed on the photovoltaic module 90. The plugging of the wiring connector will not be affected by the wear of the tooling, which may cause the wiring connector to be unable to be inserted into the socket.

[0065] It should be understood that the above-described specific embodiments of the present invention are merely illustrative or illustrative of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included within the scope of protection of the present invention. In addition, the appended claims are intended to cover all variations and modifications that fall within the scope and metes and bounds of the appended claims, or equivalents thereof.
