Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic cable installation, and particularly relates to a processing device for photovoltaic cable terminal wires. Background Technique

[0002] The conductor inside a common photovoltaic cable device is composed of 56 tinned copper wires with a diameter of 0.3 mm. When connecting adjacent photovoltaic cables in a power station, MC4 terminals are often used to connect the photovoltaic power transmission lines. MC4 terminals are divided into male and female heads. In a photovoltaic system, the number of MC4 terminals is huge. A 1MW-scale integrated solar and fishing photovoltaic power station uses approximately 2,500 sets of MC4 terminals.

[0003] MC4 terminals mainly include internal terminals and external connectors. The installation work is carried out manually at the construction site, and the installation steps are as follows: First, use a wire stripper to strip the insulating layer at the end of the photovoltaic cable, then insert the exposed conductor of the cable into the terminal, then place the terminal into a crimping tool, use the crimping tool to clamp the terminal tightly on the cable, and finally insert the terminal into the external connector and lock it.

[0004] However, in practice, the installation work of MC4 terminals in an integrated solar and fishing photovoltaic power station is high-altitude work. During this period, the staff not only needs to frequently replace tools such as wire strippers and crimping tools to install MC4 terminals on the cable, but also the conductor exposed after the wire stripper strips the insulating layer on the cable surface is extremely easy to diverge in all directions. The staff also needs to manually gather the scattered copper wires before all the copper wires can be inserted into the terminals of the MC4 terminals. This not only increases the energy consumption of the staff but also greatly increases the operation difficulty. Summary of the Invention

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0036] Embodiment 1: Refer to Figures 1 - 5 and Figure 9 , a processing device for a photovoltaic cable terminal wire, including a vertically fixed plate member 1 and an annular member 4. A notch 108 for accommodating a cable to pass through is provided in the middle of the plate member 1. An internal spline tube 101 is rotatably installed on one side of the plate member 1. A spline shaft 102 is slidably fitted inside the internal spline tube 101. A nut seat 106 is fixedly connected to the other side of the plate member 1. A screw 107 is in threaded fit with the nut seat 106. A motor 105 is fixedly connected to the surface of the plate member 1. An end face gear 104 is fixedly connected to the output end of the motor 105. A driven gear 103 is fixedly connected to the outer wall of the internal spline tube 101. The end face gear 104 and the driven gear 103 are matched with each other.

[0037] The plate member 1 is fixedly arranged to provide a supporting force for the whole device. After the motor 105 is powered on, it will drive the end face gear 104 to rotate. The rotation of the end face gear 104 will drive the driven gear 103 to rotate. The driven gear 103 drives the internal spline tube 101 to rotate, and the internal spline tube 101 drives the spline shaft 102 to rotate, thereby providing power for the whole device.

[0038] As Figures 9 - 11 , an annular gear 404 is rotatably installed on one end face of the annular member 4. A first transmission gear 405 and a second transmission gear 406 are rotatably installed on the end face of the annular member 4. The first transmission gear 405 is coaxially fixed to the end of the spline shaft 102. The second transmission gear 406 is coaxially fixedly connected to the end of the screw 107. Both the first transmission gear 405 and the second transmission gear 406 are engaged with the annular gear 404. During the rotation of the spline shaft 102, it will drive the first transmission gear 405 to rotate. The rotation of the first transmission gear 405 will drive the annular gear 404 to rotate. During the rotation of the annular gear 404, it will drive the second transmission gear 406 to rotate. The rotation of the second transmission gear 406 will drive the screw 107 to rotate. Since the screw 107 is in threaded fit with the nut seat 106 and the nut seat 106 is in a fixed state, during the rotation of the screw 107, it will move linearly in the nut seat 106, thereby driving the annular member 4 to move horizontally.

[0039] The surface of the plate member 1 is provided with a clamping structure for clamping the cable in the notch 108. The clamping structure includes a wedge-shaped spring 601, a clamping block 602 and a pressing plate 603. The clamping block 602 is slidably connected to the surface of the plate member 1, and the pressing plate 603 is slidably matched with the inclined surface of the clamping block 602. Limit blocks 6 are rotatably installed on the end faces of both the spline shaft 102 and the screw 107. One end of the spring 601 is fixedly connected to the pressing plate 603, and the other end is fixedly connected to the limit block 6.

[0040] When the ring member 4 moves horizontally, the spline shaft 102 and the screw 107 will apply pressure to the spring 601 through the limit block 6. After the spring 601 is stressed, it will apply pressure to the pressing plate 603. After the pressing plate 603 is stressed, it will apply force to the inclined surface of the clamping block 602, so that the clamping block 602 moves linearly to clamp and fix the cable entering the notch 108.

[0041] As Figures 10 - 13 , a circular rotating seat 402 is rotatably installed on the other end face of the ring member 4. One end of the rotating seat 402 penetrates through the ring member 4 and is fixedly connected to the annular gear 404. A plurality of sliding grooves 403 are formed on the other end face of the rotating seat 402. A connecting plate 5 is slidably matched in the sliding grooves 403. A blade 503 is fixedly connected to one side of the connecting plate 5, and a guide block 501 is fixedly connected to the other side of the connecting plate 5. A plurality of guide grooves 401 are formed through the ring member 4. The guide block 501 is slidably matched in the guide grooves 401. A rubber block 502 is fixedly connected to the surface of the connecting plate 5. An extension rod 407 is vertically fixedly connected to the end face of the ring member 4, and a limit plate 408 is fixedly connected to the extension rod 407.

[0042] During the rotation of the annular gear 404, it will drive the rotating seat 402 to rotate synchronously. The rotation of the rotating seat 402 will drive the connecting plate 5 to make a circular motion. The guide block 501 fixedly connected to the connecting plate 5 will also slide in the guide groove 401. Under the guiding action of the guide groove 401 on the guide block 501, the guide block 501 will cause the connecting plate 5 to move centripetally during the circular motion, so that the blade 503 on the guide block 501 cuts the outer insulating layer of the cable. And, based on the above description, it is known that the ring member 4 will move horizontally during this process. The horizontal movement of the ring member 4 will cause the blade 503 to move horizontally synchronously. Therefore, during the process of the blade 503 cutting the cable insulating layer and moving horizontally at the same time, the insulating layer at the end of the cable will be peeled off, exposing the copper wire that constitutes the internal conductor.

[0043] Moreover, during the process of the blade 503 cutting the cable insulation layer, the rubber block 502 on the connecting plate 5 will clamp on the surface of the broken insulation layer. Since the rubber block 502 will move in a circular motion together with the connecting plate 5, after the rubber block 502 clamps on the surface of the broken insulation layer, it will drive the broken insulation layer to move in a circular motion. Since the broken insulation layer is still sleeved on the cable conductor at this time, the broken insulation layer will twist the multiple copper wires constituting the conductor to a certain extent during the circular motion process, thereby preventing the copper wires from diverging in all directions after the insulation layer detaches from the conductor and ensuring that the exposed conductors are always bundled together.

[0044] Embodiment 2: As Figures 4 - 6 and Figure 8 shown, the surface of the plate member 1 is provided with a bending structure for bending the cable. The bending structure includes a fixing plate 2, the fixing plate 2 is vertically fixed on the surface of the plate member 1, a sliding groove 201 is penetratedly opened on the fixing plate 2, a connecting block 202 is slidably fitted in the sliding groove 201, a pressing roller 203 is rotatably installed on one side of the connecting block 202, a bearing seat 205 is fixed on the fixing plate 2, a driving gear 206 is rotatably fitted on the bearing seat 205, the driving gear 206 is sleeved outside the spline shaft 102, a rack 204 is vertically fixed on the outer wall of the connecting block 202, and the rack 204 meshes with the driving gear 206.

[0045] Based on the description of the above Embodiment 1, in this embodiment, the rotation of the spline shaft 102 will drive the synchronous rotation of the driving gear 206. The rotation of the driving gear 206 will drive the linear movement of the rack 204. The movement of the rack 204 will drive the pressing roller 203 to move upward through the connecting block 202, and the upward movement of the pressing roller 203 will bend the cable upward.

[0046] As Figures 6 - 8 and Figure 14 、 Figure 15 shown, a crimping mechanism is provided at the top of the plate member 1 for crimping the terminal. The crimping mechanism includes a first terminal crimping block 307, a second terminal crimping block 308 and an inverted U-shaped outer bracket 3. The outer bracket 3 is fixedly connected to the top of the plate member 1. A notch 301 is opened at the top of the outer bracket 3 to accommodate the terminal to pass through. An electric cylinder 302 is vertically fixed on the top of the outer bracket 3. The output end of the electric cylinder 302 extends vertically downward into the outer bracket 3 and is fixedly connected with a pressing block 305. A baffle 303 is fixedly connected to the outer wall of the first terminal crimping block 307. An inclined sliding groove 304 is obliquely opened on the baffle 303. The pressing block 305 is slidably fitted in the inclined sliding groove 304. The second terminal crimping block 308 is fixedly connected to the inner wall of the outer bracket 3. A tension spring 306 is fixedly connected to the outer wall of the pressing block 305 to apply an upward elastic force to the baffle 303.

[0047] A notch 301 is provided at the top of the external bracket 3, through which a terminal can be inserted between the first terminal crimping block 307 and the second terminal crimping block 308. Under the elastic force of the tension spring 306, the first terminal crimping block 307 and the second terminal crimping block 308 will fix the terminal, so that the terminal is fixed on the top of the plate member 1.

[0048] During the process of the cable being bent upward, the conductor exposed at the end of the cable will be inserted into the terminal. At this time, the pressure roller 203 is also located at a high position.

[0049] After the conductor is inserted into the terminal, the electric cylinder 302 is started. The output end of the electric cylinder 302 drives the pressure block 305 to move downward. Under the action of gravity, the first terminal crimping block 307 and the baffle 303 will also move downward synchronously. When the first terminal crimping block 307 moves downward to the bottom and abuts against the top of the pressure roller 203, the first terminal crimping block 307 stops moving downward. And the pressure block 305 driven by the electric cylinder 302 will slide downward along the inclined chute 304, thereby forcing the first terminal crimping block 307 to move towards the second terminal crimping block 308 to crimp the terminal onto the conductor exposed by the cable.

[0050] After the terminal crimping is completed, reset the motor 105 and the electric cylinder 302 to reset the device. Then, apply a downward force to the cable and the terminal to take out the cable and the terminal to complete the blanking work.

[0051] The working process and working principle are as Figure 16 and Figure 17 shown. The steps are as follows: S1: The staff holds the plate member 1 and moves it to the end of the cable to be processed. The end of the cable is sequentially passed through the notch 108, the annular gear 404 and the rotating seat 402. Since an extension rod 407 is vertically fixed on the end face of the ring member 4, and a limiting plate 408 is fixed on the extension rod 407, the end of the cable stops moving after the limiting plate 408, and the terminal is inserted from the notch 301.

[0052] S2: Start the motor 105. After the motor 105 is powered on, it will drive the end face gear 104 to rotate. The rotation of the end face gear 104 will drive the driven gear 103 to rotate. The driven gear 103 drives the internal spline tube 101 to rotate. The internal spline tube 101 drives the spline shaft 102 to rotate. The spline shaft 102 drives the first transmission gear 405 to rotate. The rotation of the first transmission gear 405 will drive the annular gear 404 to rotate; S21: During the rotation of the annular gear 404, it will also drive the second transmission gear 406 to rotate. The rotation of the second transmission gear 406 will drive the screw 107 to rotate. Since the screw 107 is in threaded cooperation with the nut seat 106 and the nut seat 106 is in a fixed state, during the rotation of the screw 107, it will move linearly in the nut seat 106, thereby driving the ring member 4 to move horizontally.

[0053] When the ring part 4 moves horizontally, the spline shaft 102 and the screw 107 will apply pressure to the spring 601 through the limit block 6. After the spring 601 is stressed, it will apply pressure to the pressure plate 603. After the pressure plate 603 is stressed, it will apply force to the inclined surface of the clamping block 602, so that the clamping block 602 moves linearly to clamp and fix the cable entering the notch 108.

[0054] S22: During the rotation of the annular gear 404, it will drive the rotating seat 402 to rotate synchronously. The rotation of the rotating seat 402 will drive the connecting plate 5 to make a circular motion. The guide block 501 fixedly connected to the connecting plate 5 will also slide in the guide groove 401. Under the guiding action of the guide groove 401 on the guide block 501, the connecting plate 5 will make a centripetal motion during the circular motion in the guide block 501, so that the blade 503 on the guide block 501 cuts the outer insulating layer of the cable.

[0055] The horizontal movement of the ring part 4 will cause the blade 503 to move horizontally synchronously. Therefore, during the process of the blade 503 cutting the cable insulating layer and moving horizontally at the same time, the insulating layer at the end of the cable will be peeled off, exposing the copper wire that constitutes the internal conductor.

[0056] S3: The rotation of the spline shaft 102 will drive the driving gear 206 to rotate synchronously. The rotation of the driving gear 206 will drive the rack 204 to move linearly. The movement of the rack 204 will drive the pressure roller 203 to move upward through the connecting block 202. The upward movement of the pressure roller 203 will bend the cable upward until the conductor exposed at the end of the cable is inserted into the terminal, and then the motor 105 is turned off.

[0057] S4: Start the electric cylinder 302. The output end of the electric cylinder 302 drives the pressure block 305 to move downward. Under the action of gravity, the first terminal crimping block 307 and the baffle 303 will also move downward synchronously. When the first terminal crimping block 307 moves downward to the bottom and abuts against the top of the pressure roller 203, the first terminal crimping block 307 stops moving downward. And the pressure block 305 driven by the electric cylinder 302 will slide downward along the inclined chute 304, so as to force the first terminal crimping block 307 to move towards the second terminal crimping block 308 to crimp the terminal on the exposed conductor of the cable.

[0058] S5: After the terminal crimping is completed, reset the motor 105 and the electric cylinder 302 to reset the device. Then, apply a downward force to the cable and the terminal to take out the cable and the terminal to complete the blanking work.

[0059] Compared with the prior art, the photovoltaic cable terminal wire processing device provided by the present invention is small in size and simple in structure, which is convenient for the staff to carry around. It is convenient for the staff to quickly connect cables and form a network at the construction site, greatly reducing the labor intensity of the staff.

[0060] The device can also automatically strangle the stripped conductor, thereby preventing the copper wire from diverging in all directions after the insulating layer detaches from the conductor, ensuring that the exposed conductors are always bundled together for easy insertion of the conductors into the terminals.

[0061] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention should cover within the protection scope of the present invention any equivalent replacement or change made according to the technical solution and inventive concept of the present invention.
