[0061] The embodiments of the present application will be described in detail by the specific embodiments, and other advantages and effects of the present application can be easily understood by those skilled in the art from the contents disclosed in the specification.

[0062] It should be understood that the structures, proportions, sizes, etc. shown in the drawings of the specification are only used to cooperate with the contents disclosed in the specification for understanding and reading by those skilled in the art, and are not used to limit the defined conditions of the embodiments of the present application, and therefore do not have technical substantial meanings.

At the same time, the terms such as "upper", "lower", "left", "right", "middle", and "one" etc. cited in the specification are only for clear description, and are not used to limit the scope of the embodiments of the present application. The change or adjustment of the relative relationship, without substantially changing the technical contents, is also considered as the scope of the embodiments of the present application.

[0063] As Figures 1 to 18As shown, the embodiment provides a solar module junction box connector and upper electrical tool plug-in mechanism, which comprises a connecting frame 1, a connector grabbing plug-in module 2 installed on the connecting frame 1, and a socket positioning module 3 installed on the connecting frame 1. The connecting frame 1 is used to be connected with a robot arm. The connector grabbing plug-in module 2 comprises connector clamping jaws 21 and plug-in driving devices 22 connected with the connector clamping jaws 21. The socket positioning module 3 comprises socket clamping positioning components 31 and tool block positioning components 32. The socket clamping positioning components 31 comprise socket positioning driving devices 311 and two socket positioning clamping blocks 312 connected with the socket positioning driving devices 311. The socket positioning driving devices 311 can drive the two socket positioning clamping blocks 312 to move along the direction of approaching each other and moving away from each other. The socket positioning clamping blocks 312 are used to contact with the side walls of a socket 41 of an upper electrical tool 4. The tool block positioning components 32 comprise tool block positioning shafts 321, which are used to contact with one end of a tool block 42 of the upper electrical tool 4. The socket 41 is fixedly installed on the other end of the tool block 42. In use, the connecting frame 1 is connected with the robot arm. The robot arm can drive the plug-in mechanism to move in various ways. When it is needed to insert a junction box connector 51 of a solar module 5 into the socket 41 of the upper electrical tool 4, the robot arm drives the plug-in mechanism to move to a set position. The connector clamping jaws 21 of the connector grabbing plug-in module 2 act to clamp the junction box connector 51. The robot arm drives the plug-in mechanism to move to a set position. The socket positioning driving devices 311 act to drive the two socket positioning clamping blocks 312 to move along the direction of approaching each other to a set position. The two socket positioning clamping blocks 312 contact with the two side walls of the socket 41 respectively during the approaching process and clamp the socket 41. The tool block positioning shafts 321 contact with one end of the tool block 42 of the upper electrical tool 4. The contact of the two socket positioning clamping blocks 312 with the two side walls of the socket 41 and the contact of the tool block positioning shafts 321 with the tool block 42 realize the positioning of the relative position between the plug-in mechanism and the upper electrical tool 4. Subsequently, the plug-in driving devices 22 act to drive the connector clamping jaws 21 and the junction box connector 51 to move along the direction of approaching the socket 41 until the junction box connector 51 is inserted into the socket 41 to a set position. The connector clamping jaws 21 release the junction box connector 51. The socket clamping positioning components 31 release the socket 41, and so on. The operation of inserting the junction box connector 51 into the socket 41 is completed. The upper electrical tool 4 can be used to test the power supply of the solar module 5. Compared with the operation completely performed by manual work, the operation mode of inserting the junction box connector 51 into the socket 41 by using the plug-in mechanism greatly improves the operation efficiency, reduces the labor intensity, and reduces the labor cost.

[0064] As Figure 10 , Figure 13 and Figure 17As shown, the joint grabbing and inserting module 2 in the embodiment further comprises a flattening positioning assembly 23 installed on the joint clamping jaw 21, the flattening positioning assembly 23 comprises a flattening driving unit 231 and a flattening piece 232 connected with the flattening driving unit 231, the flattening driving unit 231 can drive the flattening piece 232 to move, and the flattening piece 232 is used to contact the joint box joint 51. Before the robot arm drives the joint inserting mechanism to move to the set position and before the joint clamping jaw 21 grabs the joint box joint 51, the flattening driving unit 231 will first drive the flattening piece 232 to move downward to the set position, at this time the flattening piece 232 will contact the joint box joint 51 and flatten the joint box joint 51 on the solar panel of the solar module 5, so as to avoid that the joint box joint 51 is randomly tilted and causes the joint clamping jaw 21 to not accurately grab the joint box joint 51, and also to ensure that the joint box joint 51 is in the set flat state when the joint clamping jaw 21 grabs the joint box joint 51, thereby ensuring that the joint box joint 51 can be accurately inserted into the socket 41 subsequently. At the same time, as shown in the figure, Figure 17 As shown, the joint clamping jaw 21 in the embodiment comprises a clamping jaw driving device 211 and two clamping jaw blocks 212 connected with the clamping jaw driving device 211, the clamping jaw driving device 211 can drive the two clamping jaw blocks 212 to move along the direction of approaching and moving away from each other, and the flattening piece 232 is located between the two clamping jaw blocks 212. After the flattening piece 232 flattens the joint box joint 51, the clamping jaw driving device 211 drives the two clamping jaw blocks 212 to move along the direction of approaching each other, and the two clamping jaw blocks 212 move from the two sides to the middle until the joint box joint 51 is clamped. In the embodiment, the side wall of the clamping jaw block 212 is provided with an arc-shaped groove, and the joint box joint 51 comprises a clamping portion 511 and an inserting portion 512. When the two clamping jaw blocks 212 clamp the joint box joint 51, the two side walls of the clamping portion 511 of the joint box joint 51 are respectively embedded in the arc-shaped grooves of the two clamping jaw blocks 212, so as to ensure that the joint box joint 51 has a more firm clamping effect. Subsequently, the inserting portion 512 of the joint box joint 51 will be inserted into the socket 41.

[0065] As shown Figure 7 , Figure 11 and Figure 14As shown, the socket positioning module 3 in the embodiment further comprises a lifting assembly 33, which comprises a lifting driving device 331 mounted on the connecting frame 1 and a lifting frame 332 connected with the lifting driving device 331. The lifting driving device 331 can drive the lifting frame 332 to move in the up-down direction. The socket clamping positioning assembly 31 and the tool block positioning assembly 32 are respectively mounted on the two ends of the lifting frame 332. After the robot arm drives the plug-in mechanism to move to the set position, the lifting driving device 331 drives the lifting frame 332 to descend to the set position. Then the socket clamping positioning assembly 31 and the tool block positioning assembly 32 perform corresponding actions. After the actions are completed, the lifting frame 332 is lifted again. This lifting type operation mode can effectively avoid the interference between the socket positioning module 3 and other components, etc. when the socket clamping positioning assembly 31 and the tool block positioning assembly 32 are extended, and the socket clamping positioning assembly 31 and the tool block positioning assembly 32 are in a retracted state when not working.

[0066] In addition, as shown in Figure 18 In the embodiment, a detection sensor 6 is mounted on the lifting frame 332. The detection sensor 6 is used to detect whether the junction box connector 51 is inserted into the set position in the socket 41. After the junction box connector 51 is inserted into the socket 41, the detection sensor 6 is used to detect whether the junction box connector 51 is accurately inserted into the set position in the socket 41, so as to prevent the situation that the junction box connector 51 is not inserted into the set position.

[0067] As shown in Figures 7 to 9 , and Figure 16 In the embodiment, the solar module junction box connector and the upper electrician tool plug-in mechanism further comprise a tool clamping module 7 mounted on the connecting frame 1. The tool clamping module 7 comprises a tool clamping driving device 71 and two tool clamping plates 72 connected with the tool clamping driving device 71. The two tool clamping plates 72 are respectively provided with tool clamping blocks 73. The tool clamping driving device 71 can drive the two tool clamping plates 72 to move in the approaching and moving away directions. The plug-in mechanism has a clamping function for the upper electrician tool 4. The robot arm can transfer the upper electrician tool 4 to the set position. Specifically, the robot arm drives the plug-in mechanism to move to the upper electrician tool 4. The tool clamping driving device 71 drives the two tool clamping plates 72 to approach each other until the tool clamping blocks 73 on the two tool clamping plates 72 respectively contact the aluminum pipe 43 of the upper electrician tool 4 and clamp the aluminum pipe 43. The robot arm drives the upper electrician tool 4 to move to the solar module 5 through the plug-in mechanism. The tool clamping driving device 71 drives the two tool clamping plates 72 to move away from each other. The tool clamping blocks 73 release the upper electrician tool 4. The upper electrician tool 4 is transferred to the solar module 5. Then the corresponding plug-in operation is performed. The junction box connector 51 of the solar module 5 is inserted into the socket 41 of the upper electrician tool 4. Thus, the solar module 5 can be tested for power supply. Meanwhile, as shown in Figure 16As shown in the figure, the tool clamping module 7 in the embodiment also includes a rotary driving device 74 mounted on the connecting frame 1, which is connected with the tool clamping driving device 71 and can drive the tool clamping driving device 71 to rotate. When necessary, the rotary driving device 74 can be used to drive the tool clamping driving device 71 and the two tool clamping plates 72 to rotate, thereby driving the clamped upper electrical tool 4 to rotate, so as to realize the operation of turning over the upper electrical tool 4. Specifically, when it is found that the solar module 5 is reversed, the rotary driving device 74 can be used to drive the tool clamping driving device 71 and the upper electrical tool 4 to rotate by 180 degrees, thereby ensuring that when the solar module 5 is reversed, the upper electrical tool 4 can still be well assembled and connected with the solar module 5 by turning over the upper electrical tool 4, and then the power-on test is continued.

[0068] As shown in the figure, Figure 7 and Figure 16 As shown in the figure, the tool clamping module 7 in the embodiment also includes a rotary positioning assembly 75, which includes a self-locking cylinder seat 751 fixedly mounted on the rotary driving device 74 and a self-locking cylinder 752 mounted on the self-locking cylinder seat 751, and the tool clamping driving device 71 includes a clamping driving base 711 and a clamping driving cylinder mounted on the clamping driving base 711. The clamping driving base 711 is provided with a positioning notch 712. After the rotary driving device 74 drives the tool clamping driving device 71 and the upper electrical tool 4 to rotate by 180 degrees, the piston rod of the self-locking cylinder 752 is extended and inserted into the positioning notch 712, thereby realizing the positioning of the tool clamping driving device 71 and stably keeping the upper electrical tool 4 in the turned position. In the embodiment, the clamping driving base 711 is provided with the positioning notch 712 on both symmetrical sides. After being rotated to the position, the piston rod of the self-locking cylinder 752 is extended and inserted into the corresponding positioning notch 712, thereby realizing the positioning and improving the rotation accuracy, so as to ensure that the rotation angle is 180 degrees.

[0069] As shown in the figure, Figure 7 and Figure 16As shown, the tool block positioning assembly 32 in the embodiment further comprises a tool block positioning drive cylinder 322, the piston rod of which is fixedly connected with the tool block positioning shaft 321, and the tool block positioning shaft 321 is used to be inserted into the positioning hole 421 arranged at one end of the tool block. When the lifting frame 332 drives the tool block positioning assembly 32 and the socket clamping positioning assembly 31 to descend to the set position, the socket clamping positioning assembly 31 operates to realize the clamping and positioning operation of the socket, the piston rod of the tool block positioning drive cylinder 322 extends to drive the tool block positioning shaft 321 to move until the tool block positioning shaft 321 is inserted into the positioning hole 421, and the cooperation between the tool block positioning shaft 321 and the positioning hole 421 realizes more accurate positioning between the tool block and the tool block positioning assembly 32, ensures that the relative position between the socket of the upper electrical tool 4 and the plug-in mechanism and the junction 51 of the junction box is more accurate to meet the set requirement, improves the positioning accuracy, and effectively prevents the upper electrical tool 4 from being deviated under the action of gravity.

[0070] As shown in the drawings, Figure 11 In the embodiment, V-shaped grooves 411 are arranged on the two side walls of the socket 41, and protrusions are arranged on the socket positioning clamping blocks 312, which are used to be embedded in the V-shaped grooves 411. When the two socket positioning clamping blocks 312 are clamped on the two side walls of the socket 41, the protrusions on the socket positioning clamping blocks 312 are embedded in the V-shaped grooves 411, and the cooperation between the protrusions and the V-shaped grooves 411 improves the clamping and positioning accuracy. In particular, when the V-shaped grooves 411 on the front and rear side walls of the socket 41 are tightly matched with the protrusions of the two socket positioning clamping blocks 312, not only the accurate positioning of the socket 41 and the plug-in mechanism in the front-rear direction is ensured, but also the cooperation between the side walls of the V-shaped grooves 411 and the protrusions has a positioning effect on the two in the up-down direction, thereby ensuring the accurate positioning of the socket 41 and the plug-in mechanism in the front-rear and up-down directions, and improving the positioning accuracy.

[0071] In addition, as shown in the drawings, Figure 1 and Figure 2 In the embodiment, the upper electrical tool 4 specifically comprises two aluminum pipes 43, two upper electrical copper blocks 44 respectively mounted on the two aluminum pipes 43, two tool blocks 42 respectively fixedly connected with the two upper electrical copper blocks 44, and two sockets 41 respectively fixedly connected with the two tool blocks 42.

[0072] As shown in the drawings, Figures 3 to 6 , Figure 11 and Figure 14 In the embodiment, the junction box junction 51 has two types, one is a male junction 513, and the other is a female junction 514. The plug-in mechanism is used to insert the male junction 513 and the female junction 514 into the two sockets 41 respectively, realize the electrical connection between the upper electrical tool 4 and the solar module 5, and then the energization test can be performed.

[0073] The joint grabbing and plugging module 2 in the embodiment also has a waterproof function. The joint grabbing and plugging module 2 flattens the joint 51 of the terminal box based on the flattening positioning assembly 23, so as to reduce the failure rate of grabbing the joint 51 of the terminal box and plugging the joint 51 of the terminal box into the socket 41. In addition, when the solar module 5 is fed in a reversed position, the plug-in mechanism can turn the upper electric tool 4 by 180 degrees based on the rotary driving device 74, and realize positioning after turning to the position, so as to ensure that the electric connection with the solar module 5 can continue normally.

[0074] As shown in Figure 16 The rotary driving device 74 in the embodiment includes a rotary cylinder fixing plate 741 and a rotary driving cylinder 742 fixedly installed on the rotary cylinder fixing plate 741. The rotary driving cylinder 742 is specifically a gas cylinder. The rotary cylinder fixing plate 741 is processed according to the size of the rotary driving cylinder 742, and is fixedly connected with the connecting frame 1. When the positions of the male joint 513 and the female joint 514 of the solar module 5 are inconsistent with the flow direction, the rotary driving cylinder 742 is used to turn the upper electric tool 4 by 180 degrees.

[0075] The plugging driving device 22 in the embodiment includes a plugging driving cylinder 221, which is specifically a guide gas cylinder. The plugging driving cylinder 221 provides power for plugging the joint 51 of the terminal box into the socket 41. The jaw driving device 211 in the embodiment includes a clamping gas cylinder, which is connected with the two jaw blocks 212 and can drive the two jaw blocks 212 to approach or move away from each other to grab the joint 51 of the terminal box.

In addition, the flattening driving unit 231 in the embodiment includes a flattening driving gas cylinder, and the piston rod of the flattening driving gas cylinder is connected with the flattening piece 232.

[0076] The lifting driving device 331 in the embodiment includes a lifting driving cylinder, the lifting frame 332 is fixedly connected with a piston rod of the lifting driving cylinder, and the lifting frame 332 is lifted by the lifting driving cylinder. Meanwhile, based on the detection sensor 6 installed on the lifting frame 332, when the lifting frame 332 is lowered to a set position, the detection sensor 6 can accurately detect whether the terminal box connector 51 in the socket is in place. The tool block positioning driving cylinder 322 also adopts a cylinder. The socket positioning driving device 311 in the embodiment includes a socket positioning driving cylinder fixed on the lifting frame 332, two socket positioning clamping blocks 312 are connected with the socket positioning driving cylinder, and the two socket positioning clamping blocks 312 are driven by the socket positioning driving cylinder to approach each other to a set position or move away from each other to a set position.

[0077] As shown in Figure 18 The detection sensor 6 in the embodiment includes a fiber sensor 61 and a fiber amplifier 62, which are used in combination to improve detection accuracy. The end of the tool block positioning shaft 321 is provided with a tapered positioning portion, which is inserted into the positioning hole 421 at the end of the tool block 42. In combination with the clamping and positioning effect of the socket clamping positioning assembly 31 on the socket 41, the entire electrical installation tool 4 can be kept in a horizontal state on the solar module 5, thereby ensuring that the terminal box connector 51 can be accurately inserted into the socket 41, and improving the insertion success rate. In the embodiment, the tapered positioning portion is partially embedded in the positioning hole 421 and abuts against the end side wall of the positioning hole 421. The tapered design facilitates the smooth insertion of the tapered positioning portion into the positioning hole 421. In the embodiment, the fiber sensor 61 is fixedly installed on the lifting frame 332 by a fiber fixing block, and the fiber amplifier 62 is fixed on the lifting frame 332 by a fiber amplifier fixing plate. In addition, the socket positioning module 3 in the embodiment also includes other fixedly matched processing parts, such as a lifting cylinder connecting plate, a finger cylinder connecting plate, a lifting cylinder side plate, and a clamping positioning fixing block.

[0078] The above-mentioned plug-in mechanism is used to take and place the electrical installation tool 4 and perform the plug-in connection with the terminal box connector 51 of the solar module 5. The action steps are as follows:

[0079] The robot arm drives the plug-in mechanism and the tool clamping module 7 to move to the set position. After the solar module 5 reaches the set position, the tool clamping module 7 clamps the upper electrical tool 4, and the robot arm transfers the upper electrical tool 4 to the set position on the solar module 5. The tool clamping module 7 releases the upper electrical tool 4, realizing the transfer of the upper electrical tool 4 to the set position on the solar module 5. If the direction of the solar module 5 is opposite to the set direction, the rotary drive cylinder will act to rotate the upper electrical tool 4 by 180 degrees. Then, the tool clamping module 7 releases the upper electrical tool 4 and places it on the set position on the solar module 5, so that the subsequent upper electrical tool 4 can continue to be connected with the solar module 5. Under normal circumstances, the rotary drive cylinder does not rotate.

[0080] The robot arm drives the plug-in mechanism to move to the set position. The flattening positioning assembly 23 of the plug-in mechanism acts, and the flattening piece 232 presses down to flatten the junction box connector 51. The connector clamping jaw 21 clamps the junction box connector 51.

[0081] The lifting drive cylinder acts to drive the lifting frame 332 to descend to the set position. The socket positioning drive cylinder acts to drive the two socket positioning clamping blocks 312 to approach each other until the protrusions on the two socket positioning clamping blocks 312 are respectively embedded in the V-shaped grooves 411 on the two side walls of the socket 41, and the socket 41 is clamped. The tool block positioning drive cylinder 322 also acts to drive the tool block positioning shaft 321 to insert into the positioning hole 421 of the tool block 42. Then, the plug-pull drive cylinder 221 acts to drive the junction box connector 51 to move until the junction box connector 51 is inserted into the socket 41 to the set position. The detection sensor 6 detects whether the junction box connector 51 is inserted into the socket 41 to the set position.

[0082] After completion, the whole is reset, and the above plug-in action is repeatedly performed to realize the insertion of another junction box connector 51 into another socket 41.

[0083] The plug-in mechanism and the robot arm are used together in this embodiment to realize the insertion of the male connector 513 and the female connector 514 into two sockets 41, respectively. Compared with the completely manual operation mode, the production line beat and capacity are improved, and 24-hour uninterrupted operation is realized, which reduces labor intensity, saves labor cost, and improves operation efficiency. The flattening structure and the positioning structure are added to improve the success rate of plug-in operation. The optical fiber sensor 61 and the optical fiber amplifier 62 are added to confirm whether the junction box connector 51 is completely inserted into the socket 41, which meets the demand of the entire production line.

[0084] In addition, the cylinders and sensors of the plug-in mechanism in this embodiment are connected with the corresponding control units. The sensors feed back detection information to the control units, and the control units control the corresponding cylinders to perform corresponding actions.

[0085] In summary, the present application effectively overcomes the shortcomings of the prior art and has a high industrial utilization value.

[0086] The above embodiments only illustrate the principles and effects of the present application, and are not intended to limit the present application. Any modification or change made by any person skilled in the art without departing from the spirit and scope of the present application shall be covered by the claims of the present application.
