Detailed Description

As shown in the figures, an automatic assembly machine for photovoltaic connection harnesses comprises: the wire stripping device comprises a pay-off rack 101, a transition wheel 102, a first conveying wheel 103, a cutting mechanism 104, a linear sliding table 105, a riveting and pressing mechanism 107, a soldering mechanism 108, a connector inserting mechanism 109, a conveying belt 111, a wire harness section 112, a second conveying wheel 113, a straightening mechanism 200, a wire conduit 300, a wire stripping mechanism 400 and a steering clamping mechanism 500.

The pay-off rack 101 is provided with a bearing seat, the bearing seat is provided with a rotating shaft, and the cable reel can be arranged on the rotating shaft, so that the cable reel can rotate relative to the pay-off rack 101. When the connection wire wound on the cable drum is pulled, the cable drum can be rotated to pay out the wire. The cable drum is rotatably placed on the pay-off stand 101.

The first conveying wheels 103 are connected with the motor, the motor is started, and the motor can drive the first conveying wheels 103 to rotate, so that the first conveying wheels 103 can pull the connecting line, and the connecting line is conveyed to the straightening mechanism 200. Since the pay-off rack 101 and the first delivery wheel 103 tend to be different in height and tend to have a distance, a transition wheel 102 is provided between the first delivery wheel 103 and the pay-off rack 101.

Since the connection wire is wound on the cable drum and thus bent, a straightening mechanism 200 is provided in order to straighten the connection wire. Specifically, the straightening mechanism 200 includes a box 201 having a hollow cavity, through holes 202 are symmetrically formed on the left and right sides of the box 201, and the connecting wires can be inserted into the hollow cavity through the through hole 202 on one side and then pass through the through hole 202 on the other side. An upper pressing plate 203 is installed in the box body 201 in a vertically sliding mode, the upper end of the upper pressing plate 203 is fixedly connected with a piston rod of a first air cylinder 205, and therefore the piston rod can be driven to drive the upper pressing plate 203 to perform vertical linear motion through controlling the first air cylinder 205. A row of upper rollers 204 is rotatably mounted on the lower end of the upper platen 203. Each upper roller 204 should be in a straight line. A lower press plate 206 is arranged below the upper press plate 203, and a row of lower rollers 207 is arranged at the upper end of the lower press plate 206 corresponding to the upper rollers 204. The first connecting line thickness control cylinder 205 can drive the piston rod to drive the upper pressing plate 203 to move to a proper height, so that the upper roller 204 and the lower roller 207 are respectively contacted with the upper side and the lower side of the connecting line, the connecting line is enabled to receive the force applied by the upper roller 204 and the lower roller 207 in the conveying process, and the connecting line is straightened. Generally, the horizontal height of the upper tangent plane of the lower roller 207 should be located between the upper hole wall and the lower hole wall of the through hole 202, in order to enable the lower roller 207 to have a buffering effect, the connecting line can be reasonably controlled between the upper hole wall and the lower hole wall of the through hole 202 according to the difference of the thickness of the connecting line, the connecting line is enabled to be not in contact with the hole wall of the through hole 202 as much as possible, a buffering rod is fixedly connected to the lower end of the lower pressing plate 206, the lower portion of the buffering rod is inserted into a buffering groove formed in the box 201, and a first spring 208 is sleeved on the buffering rod. It should be noted that when the first spring 208 is fully compressed, the upper tangent plane of the lower roller 207 should be slightly higher than the lower hole wall of the through hole 202, so as not to contact the connecting wire with the lower hole wall of the through hole 202, which may cause the sheath of the connecting wire to be damaged by friction.

The second conveying wheels 113 are connected with a motor, and the motor can drive the second conveying wheels 113 to rotate, so that the pair of second conveying wheels 113 can pull the straightened connecting wire to convey the connecting wire to the cutting mechanism 104.

In order to avoid the bending deformation of the connecting line between the second conveying wheel 113 and the cutting mechanism 104, a conduit 300 is arranged between the second conveying wheel 113 and the cutting mechanism 104, the conduit 300 is a straight cylinder, the connecting line passes through the cylinder, and the connecting line in the cylinder can avoid the bending deformation caused by collision or other reasons. Specifically, conduit 300 includes a plurality of end to end's body 301, and body 301 is cylindricly, and body 301 both ends are equipped with connecting portion 302. Mounting holes are uniformly distributed on the connecting portion 302, so that two adjacent pipe bodies 301 can be fixedly connected together through bolts. In order to prevent the outer skin of the connecting wire from being damaged due to the friction between the connecting wire and the inner wall of the tube 301, a plurality of steel balls 303 are rotatably mounted on the inner wall of the tube 301 along the circumferential direction.

The cutting mechanism 104 may set a cutting length of the connecting wire, which may be cut into a predetermined length of the strand segment 112. A conveying belt 111 is provided at one end of the cutting mechanism 104 remote from the conduit 300, and a wire stripping mechanism 400, a riveting mechanism 107, a soldering mechanism 108, and a connector insertion mechanism 109 are provided symmetrically on both sides of the conveying belt in the conveying direction of the conveying belt 111. The wire stripping mechanism 400 is used to cut off a portion of the outer skin at both ends of the wire harness segment 112 and strip the outer skin. The crimping mechanism 107 crimps the end of the harness section 112 and the terminal. The soldering mechanism 108 fixes the head of the wire harness section 112 having the terminal and the terminal by soldering. The plug connector mechanism 109 plugs a cable having terminals into the connector.

Two sides of the conveying belt 111 are symmetrically provided with a pair of linear sliding tables 105, the wire stripping mechanism 400 is mounted on the linear sliding tables 105, and the linear sliding tables 105 are used for driving the wire stripping mechanism 400 to move linearly towards the direction close to or far away from the conveying belt 111. Specifically, the wire stripping mechanism 400 includes a lower fixing block 401 fixedly mounted with the slider of the linear sliding table 105, a lower cutter 403 and an upper fixing block 402 fixedly mounted on the lower fixing block 401 through bolts, an upper cutter 404 is mounted on the upper fixing block 402 in a vertically slidable manner, and the upper cutter 404 is fixedly connected with the piston rod of the second cylinder 405. When wire stripping is needed, the linear sliding table 105 drives the wire stripping mechanism 400 to move to a set position, so that two ends of the wire harness section 112 respectively penetrate between an upper cutter 404 and a lower cutter 403 of the wire stripping mechanism 400 arranged on two sides of the conveying belt 111, the control cylinder II 405 drives the upper cutter 404 to move downwards, so that the outer skin of the wire harness section 112 is cut off, and the linear sliding table 105 drives the wire stripping mechanism 400 to move towards a direction away from the conveying belt 111, so that the outer skin is stripped by the upper cutter 404 and the lower cutter 403 together. In order to collect the peeled outer skins, a waste frame 106 is provided below the linear slide table 105.

A plurality of rotary bases are fixedly mounted on the conveyor belt 111, a steering clamping mechanism 500 is rotatably mounted on the rotary bases, the steering clamping mechanism 500 is used for clamping the cut-off wire harness section 112, and then the wire harness section 112 is rotated by 90 degrees, so that two ends of the wire harness section 112 are respectively positioned on two sides of the conveyor belt 111, and two ends of the wire harness section 112 are simultaneously processed. Specifically, the steering clamping mechanism 500 includes a rotary table 502 cooperatively mounted on a rotary seat, a base 501 is fixedly mounted on the upper end of the rotary table 502, and the rotary seat can drive the rotary table 502 and the base 501 to rotate together. A top seat 506 is installed in a sliding groove 505 formed in the base 501, a radial through groove 511 is formed in the middle of the upper end of the top seat 506, a cavity is formed in the top seat 506, a T-shaped rod 508 is arranged in the cavity, and one end of a long rod of the T-shaped rod 508 penetrates through a connecting hole formed in the top seat 506 and is fixedly connected with a clamping block 510 arranged in the radial through groove 511. A second spring 509 is sleeved on a long rod of the T-shaped rod 508 in the cavity, one side of a short rod of the T-shaped rod 508 is provided with a first electromagnet 507, and a storage battery and a circuit board are installed in the cavity. The conveying belt 111 drives the steering clamping mechanism 500 to move to one end of the cutting mechanism 104, the radial through groove 511 is transversely arranged, the electromagnet I507 is electrified, the electromagnet I507 adsorbs the short rod of the T-shaped rod 508, the spring II 509 is stretched, the transversely conveyed wire harness section 112 is inserted between the two clamping blocks 510 of the radial through groove 511, then the electromagnet I507 is powered off, the spring II 509 returns, and the two clamping blocks 510 clamp the wire harness section 112. The rotary base is controlled to drive the rotary table to rotate by 90 degrees, so that the wiring harness section 112 is converted into a vertical direction, the conveying belt 111 conveys, turns to and clamps the mechanism 500 and moves towards the next station together with the wiring harness section 112, and therefore the two ends of the wiring harness section 112 can be conveniently subjected to wire stripping, riveting, soldering and connector inserting processing in sequence. The finished wire harness segment 112 is conveyed to one end of the conveyor belt 111, a finished frame 110 is arranged below the conveyor belt 111, and when the steering clamping mechanism 500 moves to the upper side of the finished frame 110 together with the finished wire harness segment 112. The conveyer belt 111 rotates to enable the opening of the radial through groove 511 to face downwards, the electromagnet I507 is electrified, the two clamping blocks 510 enable the wire harness section 112 to be loosened, and the wire harness section 112 falls into the finished product frame 110. The rotary seat controls the rotary table 502 to rotate 90 degrees, so that the radial through groove 511 is horizontally arranged, and the next workpiece taking is facilitated. In order to adapt to processing of the wire harness sections 112 with different lengths, when the longer wire harness section 112 turns, if the distance between the adjacent turning clamping mechanisms 500 is shorter, the transverse wire harness section 112 will touch the adjacent turning clamping mechanisms 500, so that the wire harness section 112 is bent and deformed, and the subsequent processing is inconvenient; moreover, the heights of the wire stripping mechanism 400, the riveting mechanism 107, the soldering mechanism 108 and the connector inserting mechanism 109 are not easy to change flexibly, and when the height of the discharge port of the cutting mechanism 104 is high, the cut wire harness section 112 can fall into the radial through groove 511 positioned below under the action of gravity. In order to solve the problem, a top seat 506 is installed in a sliding groove 505 in a vertically sliding manner, a guide rod is fixedly connected to the lower end of the top seat 506, the lower portion of the guide rod is inserted into a guide groove formed in the base 501, a spring III 504 is sleeved on the upper portion of the guide rod, and an electromagnet II 503 is arranged at the bottom of the sliding groove 505. When in conveying, the second electromagnet 503 is electrified, so that the third spring 504 is compressed; when the wire harness section 112 needs to be steered, the second electromagnet 503 is powered off, and the top seat 506 moves upwards under the action of the elastic force of the third spring 504, so that the radial through groove 511 of the steering clamping mechanism 500 for taking materials is higher than other steering clamping mechanisms 500; the transverse wire harness section 112 is clamped and turned backwards, and then the electromagnet II 503 is electrified, so that the top seat 506 moves downwards and returns to the normal machining height, and deformation caused by collision when the transverse wire harness section 112 turns is avoided.
