Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic wire harness production, and particularly to a high-density multi-core photovoltaic wire harness production device and its production method. Background Art

[0002] At present, for a photovoltaic power generation system, a common photovoltaic power generation system uses solar panels for concentrating power generation. The potential for the development and utilization of solar energy resources is very broad, and the output of solar cells and components has been steadily increasing year by year. As a solar photovoltaic cable connecting photovoltaic modules and inverters, there are also huge business opportunities. During the assembly of solar photovoltaic systems, a large number of wire harnesses are required for connection.

[0003] During the production process of wire harnesses, it is necessary to strip the insulating layer at the end of the wire harness and install a connection plug. During the process of stripping the wire harness, the length of the wire harness cannot be precisely controlled, resulting in inconsistent outer skin lengths when the wire harness is cut subsequently, thereby causing the final product to be unable to be precisely assembled and the connector to be unable to be inserted, affecting the quality of the product. Summary of the Invention

[0004] The purpose of the present invention is to provide a high-density multi-core photovoltaic wire harness production device and its production method to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present invention is realized through the following technical solutions:

One side wall of one end of the plugging sliding sleeve contacts the inner wall of the special-shaped pipe. One end of a return spring is fixedly connected to one side wall of the inner wall of the annular shell. The bottom of the annular shell is communicated with an air pipe, and one end of the air pipe penetrates through the fixing rod and is communicated with one side of the outer wall of the loading shell.

[0011] Furthermore, a clamping component is arranged on the top of the lifting plate. The clamping component includes round rods fixedly connected to both sides of the top of the lifting plate. The top of the round rod is fixedly connected with a sliding plate. The outer wall of the sliding plate is slidably connected to the inner cavity of the loading shell. Three sliding frames penetrate through and are slidably connected to the top of the sliding plate. A clamping plate is fixedly connected to the bottom of the sliding frame.

[0012] Furthermore, extrusion springs are respectively fixedly connected to both sides of the top of the clamping plate.

[0015] A production method of a high-density multi-core photovoltaic wire harness production device includes the following steps;

[0016] Step 1: Traction wire harness;

[0017] Step 2: Heating wire harness;

[0018] Step 3: Stabilizing wire harness;

[0019] Step Four: Cut the wire harness.

[0020] The present invention has the following beneficial effects:

[0021] (1) In the present invention, the wire harness is sleeved on the inner wall of the loading shell. Subsequently, one end of the wire harness is aligned and clamped on the inner wall of the gripper. The electric telescopic rod is started, and the electric telescopic rod drives the moving plate to move. The moving plate drives the bent plate to move. The bent plate drives the gripper to move. The gripper drives the wire harness to move, enabling multiple wire harnesses to move together. This facilitates subsequent peeling of the outer skin of the wire harness, ensuring that the peeling lengths of multiple wire harnesses are equal, thereby improving the subsequent production efficiency of the wire harness. When the moving plate moves, the moving plate drives the rotating plate to move. Limited by the vertical groove, the rotating plate drives the lifting block to vertically descend along the inner wall of the vertical groove. The lifting block drives the pressing plate to move downward. When the pressing plate moves downward, it contacts the top of the vertical plate, causing the vertical plate to vertically descend. The vertical plate drives the lifting plate to descend. Through the setting of the heater, the heater heats up the air flow at the bottom of the inner cavity of the loading shell. When the lifting plate descends, it squeezes the air flow at the bottom of the inner cavity of the loading shell. The hot air flow enters the interior of the trachea, passes through the trachea and enters the interior of the annular shell, passes through the annular shell and enters the interior of the special-shaped tube, and is discharged outward through the special-shaped tube, heating up the sliding outer skin of the wire harness, softening the outer skin of the wire harness, facilitating subsequent outer skin cutting work, and improving the subsequent production efficiency of the wire harness.

[0022] (2) In the present invention, when the lifting plate no longer moves downward, the air flow at the bottom of the inner cavity of the loading shell is no longer squeezed. At this time, due to the elastic deformation of the return spring, the return spring drives the plugging sliding sleeve to move along the outer wall of the cross bar. During the movement of the plugging sliding sleeve, it plugs the opening of the special-shaped tube, preventing the hot air flow from continuing to be discharged outward. At this time, the heater continues to heat up the air flow at the bottom of the inner cavity of the loading shell, enabling the air flow to be continuously heated, facilitating subsequent heating of the wire harness by the hot air flow.

[0023] (3) In the present invention, when the lifting plate descends, the lifting plate drives the round rod to descend. The round rod drives the sliding plate to descend. The sliding plate drives the sliding frame to descend. The sliding frame drives the clamping plate to descend. During the descent of the clamping plate, it contacts the outer wall top of the sliding wire harness through the inner wall of the first card hole, slightly squeezing the top of the wire harness, thereby increasing the tension of the moving wire harness, facilitating the subsequent cutting effect of the device on the wire harness, and improving the subsequent production efficiency of the wire harness from the side.

[0024] (4) In the present invention, when the clamping plate continues to be pressed downwards, it is subjected to the reaction force of the wire harness. The clamping plate drives the sliding frame to move upwards. The sliding frame drives the rotating bar to move upwards. Restricted by the limiting hole, the rotating bar drives the slider to slide along the inner wall of the limiting hole. The slider drives the connecting rod to move. The two connecting rods move closer to each other. During the movement of the connecting rods, the outer wall of the wire harness is clamped through the arrangement of the second clamping holes, further improving the tension of the wire harness during sliding. At the same time, the connecting rod drives the round bar to move. The round bar drives the semi-circular blade to move. The two semi-circular blades move closer to each other, thereby cutting the outer skin of the wire harness. At this time, the gripper drives the entire wire harness to continue to move forward slightly. Since the part of the wire harness located inside the loading shell is clamped and fixed, the cut outer skin of the wire harness is slightly pulled out by the traction force of the gripper, facilitating the subsequent workers' efficiency in pulling out the outer skin of the wire harness and making the length of the pulled-out outer skin equal.

[0025] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] The wire harness production mechanism 5, the wire harness production mechanism 5 includes a moving plate 51 fixedly connected to the movable end of the electric telescopic rod 4. A bent plate 52 is fixedly connected to the top of the moving plate 51. A clamping device 53 is fixedly connected to one end of the bent plate 52 away from the moving plate 51. Three wire harnesses 54 are in contact with the inner wall of the clamping device 53. The wire harnesses 54 are sleeved on the inner wall of the loading shell 3. Then, one end of the wire harnesses 54 is aligned and clamped on the inner wall of the clamping device 53. The electric telescopic rod 4 is started. The electric telescopic rod 4 drives the moving plate 51 to move. The moving plate 51 drives the bent plate 52 to move. The bent plate 52 drives the clamping device 53 to move. The clamping device 53 drives the wire harnesses 54 to move, enabling multiple wire harnesses 54 to move together. When it is convenient to strip the outer skin of the wire harnesses 54 later, the stripping lengths of the multiple wire harnesses 54 are equal, improving the subsequent production efficiency of the wire harnesses 54. One end of the outer wall of the wire harnesses 54 is slidably connected to the inner wall of the loading shell 3. A traction assembly 55 is arranged on the top of the moving plate 51.

[0041] The traction assembly 55 includes rotating plates 551 rotatably connected to both sides of the top of the moving plate 51. A lifting block 552 is rotatably connected to the top end of the rotating plate 551. Vertical grooves 553 are respectively formed on both sides of the inner wall of the support plate 2. One end of the outer wall of the lifting block 552 is slidably connected to the inner wall of the vertical groove 553. An extrusion plate 554 is fixedly connected between the two lifting blocks 552. Vertical plates 555 penetrate and are slidably connected to both sides of the top of the loading shell 3.

[0042] A lifting plate 556 is fixedly connected to the bottom of the vertical plate 555. The outer wall of the lifting plate 556 is slidably connected to the inner wall of the loading shell 3. A spring 557 is fixedly connected to the bottom of the lifting plate 556. The bottom of the spring 557 is fixedly connected to the inner cavity of the loading shell 3.

[0043] A heating assembly 56 is arranged in the inner cavity of the loading shell 3. The heating assembly 56 includes a heater 561 fixedly connected to the bottom of the inner cavity of the loading shell 3. Three fixing rods 562 are fixedly connected to the top of the bottom plate 1 near the electric telescopic rod 4. A circular shell 563 is fixedly connected to the top of the fixing rods 562. Four cross bars 564 are fixedly connected to one side of the inner wall of the circular shell 563.

[0044] One end of the outer wall of the cross bar 564 is slidably connected with a sealing sliding sleeve 565. Four special-shaped pipes 566 are respectively communicated with the periphery of one side of the outer wall of the annular shell 563. One end side wall of the sealing sliding sleeve 565 contacts the inner wall of the special-shaped pipe 566. One end of the sealing sliding sleeve 565 is fixedly connected with a reset spring 567. One end of the reset spring 567 is fixedly connected with one side of the inner wall of the annular shell 563. The bottom of the annular shell 563 is communicated with an air pipe 568. When the moving plate 51 moves, the moving plate 51 drives the rotating plate 551 to move. Limited by the vertical groove 553, the rotating plate 551 drives the lifting block 552 to vertically descend along the inner wall of the vertical groove 553. The lifting block 552 drives the extrusion plate 554 to move downward. When the extrusion plate 554 moves downward, it will contact the top of the vertical plate 555, causing the vertical plate 555 to vertically descend. The vertical plate 555 drives the lifting plate 556 to descend. Through the setting of the heater 561, the heater 561 heats up the air flow at the bottom of the inner cavity of the loading shell 3. When the lifting plate 556 descends, it will squeeze the air flow at the bottom of the inner cavity of the loading shell 3. The hot air flow enters the inside of the air pipe 568. The hot air flow enters the inside of the annular shell 563 through the air pipe 568. The hot air flow enters the inside of the special-shaped pipe 566 through the annular shell 563. The hot air flow is discharged outward through the special-shaped pipe 566 to heat up the outer skin of the sliding wire harness 54, softening the outer skin of the wire harness 54, facilitating the subsequent work of outer skin cutting, improving the subsequent production efficiency of the wire harness 54. One end of the air pipe 568 penetrates through the fixing rod 562 and is communicated with one side of the outer wall of the loading shell 3. When the lifting plate 556 no longer moves downward, the air flow at the bottom of the inner cavity of the loading shell 3 is no longer squeezed. At this time, due to the elastic deformation of the reset spring 567, the reset spring 567 drives the sealing sliding sleeve 565 to move along the outer wall of the cross bar 564. During the movement of the sealing sliding sleeve 565, it will block the opening of the special-shaped pipe 566 to prevent the hot air flow from continuing to be discharged outward. At this time, the heater 561 continues to heat up the air flow at the bottom of the inner cavity of the loading shell 3, enabling the air flow to be continuously heated up, facilitating the subsequent heating work of the hot air flow on the wire harness 54.

[0045] Embodiment 2, a clamping component 57 is arranged on the top of the lifting plate 556. The clamping component 57 includes round rods 571 fixedly connected to both sides of the top of the lifting plate 556. The top of the round rod 571 is fixedly connected with a sliding plate 572. The outer wall of the sliding plate 572 is slidably connected to the inner cavity of the loading shell 3. Three sliding frames 573 penetrate through and are slidably connected to the top of the sliding plate 572. The bottom of the sliding frame 573 is fixedly connected with a clamping plate 574.

[0046] On both sides of the top of the clamping plate 574, extrusion springs 575 are fixedly connected respectively. The top of the extrusion spring 575 is fixedly connected to the bottom of the sliding plate 572. On one side of the inner cavity of the loading shell 3, a first clamping hole 576 is opened. At both ends of the inner cavity side of the loading shell 3 near the first clamping hole 576, second clamping holes 577 are respectively opened. When the lifting plate 556 descends, the lifting plate 556 drives the round rod 571 to descend. The round rod 571 drives the sliding plate 572 to descend. The sliding plate 572 drives the sliding frame 573 to descend. The sliding frame 573 drives the clamping plate 574 to descend. During the descent of the clamping plate 574, it contacts the top of the outer wall of the moving wire harness 54 through the inner wall of the first clamping hole 576, and slightly squeezes the top of the wire harness 54, thereby increasing the tension of the moving wire harness 54, facilitating the cutting effect of the subsequent device on the wire harness 54, and improving the subsequent production efficiency of the wire harness 54.

[0047] A cutting assembly 58 is arranged on the outer wall of the sliding frame 573. The cutting assembly 58 includes rotating bars 581 rotatably connected to both sides of the top of the sliding frame 573. Six limiting holes 582 are respectively opened on the top of the sliding plate 572. Two limiting holes 582 are set as a group. One end of the rotating bar 581 away from the sliding frame 573 is rotatably connected to a slider 583. The outer wall of the slider 583 is slidably connected to the inner wall of the limiting hole 582. The bottom of the slider 583 is fixedly connected to a connecting rod 584. When the clamping plate 574 continues to press down, due to the reaction force of the wire harness 54, the clamping plate 574 drives the sliding frame 573 to move upward. The sliding frame 573 drives the rotating bar 581 to move upward. Limited by the limiting hole 582, the rotating bar 581 drives the slider 583 to slide along the inner wall of the limiting hole 582. The slider 583 drives the connecting rod 584 to move. The two connecting rods 584 move closer to each other. During the movement of the connecting rod 584, the outer wall of the wire harness 54 is clamped through the setting of the second clamping hole 577, further increasing the tension of the moving wire harness 54.

[0048] One side of the bottom end of the connecting rod 584 is fixedly connected with a clamping frame 585. Six square holes 587 are respectively formed on one side of the outer wall of the loading shell 3. Two square holes 587 are set as a group. One side of the connecting rod 584 is fixedly connected with a round bar 589. One end of the outer wall of the round bar 589 is slidably connected to the inner wall of the square hole 587. One end of the outer wall of the round bar 589 is fixedly connected with a fixing ring 586. The fixing ring 586 is arranged outside the loading shell 3. One side of the fixing ring 586 is fixedly connected with a semi-circular blade 588. The connecting rod 584 drives the round bar 589 to move. The round bar 589 drives the semi-circular blade 588 to move. The two semi-circular blades 588 move closer to each other, so as to cut the outer skin of the wire harness 54. At this time, the clamp 53 drives the whole wire harness 54 to continue to move forward a small amount. Because the part of the wire harness 54 located inside the loading shell 3 is clamped and fixed, the cut outer skin of the wire harness 54 is pulled out a small amount by the traction force of the clamp 53, which is convenient for the subsequent staff to pull out the outer skin of the wire harness 54 efficiently.

[0049] A production method of a high-density multi-core photovoltaic wire harness production device includes the following steps;

[0050] Step 1: Traction of the wire harness 54;

[0051] Step 2: Heating of the wire harness 54;

[0052] Step 3: Stabilization of the wire harness 54;

[0053] Step 4: Cutting of the wire harness 54.

[0054] During use, the wire harness 54 is sleeved on the inner wall of the loading shell 3. Subsequently, one end of the wire harness 54 is aligned and clamped on the inner wall of the gripper 53. The electric telescopic rod 4 is started, and the electric telescopic rod 4 drives the moving plate 51 to move. The moving plate 51 drives the bent plate 52 to move. The bent plate 52 drives the gripper 53 to move. The gripper 53 drives the wire harness 54 to move, enabling multiple wire harnesses 54 to move together. This facilitates the subsequent peeling of the outer skin of the wire harness 54, ensuring that the peeling lengths of multiple wire harnesses 54 are equal, thereby improving the subsequent production efficiency of the wire harness 54. When the moving plate 51 moves, the moving plate 51 drives the rotating plate 551 to move. Restricted by the vertical groove 553, the rotating plate 551 drives the lifting block 552 to vertically descend along the inner wall of the vertical groove 553. The lifting block 552 drives the pressing plate 554 to move downward. When the pressing plate 554 moves downward, it comes into contact with the top of the vertical plate 555, causing the vertical plate 555 to vertically descend. The vertical plate 555 drives the lifting plate 556 to descend. Through the setting of the heater 561, the heater 561 heats up the air flow at the bottom of the inner cavity of the loading shell 3. When the lifting plate 556 descends, it squeezes the air flow at the bottom of the inner cavity of the loading shell 3. The hot air flow enters the interior of the air pipe 568. The hot air flow enters the interior of the annular shell 563 through the air pipe 568. The hot air flow enters the interior of the special-shaped pipe 566 through the annular shell 563. The hot air flow is discharged outward through the special-shaped pipe 566, heating up the outer skin of the sliding wire harness 54, softening the outer skin of the wire harness 54, facilitating the subsequent work of outer skin cutting, and improving the subsequent production efficiency of the wire harness 54.

[0055] When the lifting plate 556 stops moving downward, the air flow at the bottom of the inner cavity of the loading shell 3 is no longer squeezed. At this time, due to the elastic deformation of the return spring 567, the return spring 567 drives the plugging sleeve 565 to move along the outer wall of the cross bar 564. During the movement of the plugging sleeve 565, it plugs the opening of the special-shaped pipe 566, preventing the hot air flow from continuing to be discharged outward. At this time, the heater 561 continues to heat up the air flow at the bottom of the inner cavity of the loading shell 3, enabling the air flow to be continuously heated up, facilitating the subsequent heating work of the hot air flow on the wire harness 54.

[0056] When the lifting plate 556 descends, the lifting plate 556 drives the round rod 571 to descend. The round rod 571 drives the sliding plate 572 to descend. The sliding plate 572 drives the sliding frame 573 to move downward. The sliding frame 573 drives the clamping plate 574 to move downward. During the downward movement of the clamping plate 574, it comes into contact with the outer wall top of the sliding wire harness 54 through the inner wall of the first clamping hole 576, slightly squeezing the top of the wire harness 54, thereby increasing the tension of the moving wire harness 54, facilitating the subsequent cutting effect of the device on the wire harness 54, and indirectly improving the subsequent production efficiency of the wire harness 54.

[0057] When the clamping plate 574 continues to press down, it is subjected to the reaction force of the wire harness 54. The clamping plate 574 drives the sliding frame 573 to move upward. The sliding frame 573 drives the rotating bar 581 to move upward. Limited by the limiting hole 582, the rotating bar 581 drives the slider 583 to slide along the inner wall of the limiting hole 582. The slider 583 drives the connecting rod 584 to move. The two connecting rods 584 move closer to each other. During the movement of the connecting rod 584, the outer wall of the wire harness 54 is clamped through the setting of the second clamping hole 577, further improving the tension of the wire harness 54 during sliding. At the same time, the connecting rod 584 drives the round bar 589 to move. The round bar 589 drives the semi-circular blade 588 to move. The two semi-circular blades 588 move closer to each other, thereby cutting the outer skin of the wire harness 54. At this time, the gripper 53 drives the entire wire harness 54 to continue to move forward a small amount. Because the part of the wire harness 54 located inside the loading shell 3 is clamped and fixed, the cut outer skin of the wire harness 54 is pulled out a small amount by the traction force of the gripper 53, facilitating the subsequent staff to pull out the outer skin of the wire harness 54 efficiently.
