[0002] Wire harness connectors, also known as grommets, are positioning joints for connecting electronic circuits and are widely used in digital products, home appliances, and the automotive industry. Currently, most commonly used wire harness connectors are manufactured through injection molding, often leaving excess material at both ends. If not removed, this will affect the normal use of the connector.

[0003] In existing technologies, excess material is mostly removed manually. However, manual removal is time-consuming, labor-intensive, and inefficient, and can easily result in uneven cut surfaces, leading to poor product quality control. Therefore, it is necessary to design a device that can replace manual removal of excess material from connector surfaces to solve the aforementioned technical problems. Utility Model Content

Detailed Implementation

[0028] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. However, those skilled in the art will understand that the embodiments described below are only some embodiments of this utility model, not all embodiments, and are only used to illustrate this utility model, and should not be regarded as limiting the scope of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Where specific conditions are not specified in the embodiments, conventional conditions or conditions recommended by the manufacturer shall be followed. Where the manufacturers of reagents or instruments are not specified, they are all conventional products that can be purchased commercially.

[0029] like Figure 1-7 As shown, a connector cutting fixture includes a mounting base 1. A turntable 2 is rotatably mounted on the upper surface of the mounting base 1 via a rotating shaft. Multiple positioning fixtures 3 for carrying connectors 7 are provided at equal intervals along the circumferential direction on the upper surface of the turntable 2. A cutting mechanism 4 and a conveying mechanism 5 are fixedly provided on the upper surface of the mounting base 1. When the turntable 2 rotates, the multiple positioning fixtures 3 cooperate with the cutting mechanism 4 and the conveying mechanism 5 in sequence.

[0030] In practice, the shearing mechanism 4 is used to shear the head 701 of the connector 7. The turntable 2 transports the connector 7 to be sheared to the shearing mechanism 4, which then sequentially shears off the head 701 of the connector 7. The conveying mechanism 5 is used to place the connector 7 to be sheared onto the positioning fixture 3. Ultimately, the shearing of the head 701 of the connector 7 can be continuously performed, thereby replacing manual shearing operations and improving work efficiency.

[0031] In this embodiment, the shearing mechanism 4 includes a shearing frame 401 fixedly installed on the upper surface of the mounting base 1. A first cylinder 402 is fixedly installed on the shearing frame 401. The output shaft of the first cylinder 402 extends vertically downward through the shearing frame 401. A cutter 403 is installed at the output end of the first cylinder 402. The cutter 403 is U-shaped. Both ends of the cutter 403 can simultaneously cut off the material heads 701 at both ends of the connector 7.

[0032] The positioning fixture 3 is provided with a positioning cavity 301 for accommodating the connector 7. The positioning cavity 301 has openings at both the upper and lower ends, and a material head support plate 302 is fixedly installed on both sides of the positioning cavity 301. When cutting, the material head support plate 302 abuts against the bottom surface of the material head 701.

[0033] The mounting base 1 and the turntable 2 are respectively provided with a first through hole 101 and a second through hole 201 at the positions corresponding to the positioning cavity 301, and the positioning cavity 301, the first through hole 101 and the second through hole 201 are aligned vertically.

[0034] In this embodiment, the mounting base 1 and the turntable 2 are respectively provided with a third through hole 102 and a fourth through hole 202. The side of the material head support plate 302 away from the positioning cavity 301 is an inclined surface, and the bottom end of the inclined surface communicates with the third through hole 102. The third through hole 102 and the fourth through hole 202 are aligned vertically. If the positioning fixture 3 is set near the edge of the turntable 2, then only one fourth through hole 202 is provided on the inner side of the turntable 2, depending on the actual situation.

[0035] In use, the connector 7 is placed into the positioning cavity 301. The material heads 701 at both ends of the connector 7 are located above the material head support plate 302. The first cylinder 402 extends, driving the cutter 403 to move downward, thereby cutting off the excess material head 701.

[0036] In this embodiment, partition plates 103 are provided on both sides of the bottom of the first through hole 101, a finished product box is provided below the first through hole 101, and a waste box is provided below the third through hole 102. The partition plates 103 are used to guide and isolate the material head 701 and the finished product connector 7 to prevent the finished product connector 7 and the material head 701 from being mixed.

[0037] After the stub 701 of connector 7 is cut off, the first cylinder 402 continues to extend, pushing the connector 7 with the cut-off stub 701 downwards through the positioning cavity 301, the second through hole 201, and the first through hole 101 in sequence, before falling into the finished product box. The cut-off stub 701 slides down the inclined surface of the stub support plate 302, passes through the fourth through hole 202 and the third through hole 102, and falls into the waste bin. This separates the finished connector 7 from the excess stub 701, eliminating the need for manual sorting.

[0038] In this embodiment, the conveying mechanism 5 includes a first mounting plate fixedly mounted above the mounting base 1. A first guide rail 501 is fixedly mounted horizontally on the first mounting plate. A first slider 503 is slidably mounted on the first guide rail 501. A first lead screw 502 is rotatably mounted on the first mounting plate. The first slider 503 is threadedly connected to the first lead screw 502. A first motor 504 is fixedly mounted on the first mounting plate. The output shaft of the first motor 504 is fixedly connected to one end of the first lead screw 502. A second mounting plate is fixedly mounted on the first slider 503.

[0039] The first motor 504 drives the first lead screw 502 to rotate, and the first lead screw 502 drives the first slider 503 to slide horizontally along the first guide rail 501, thereby driving the second mounting plate to move.

[0040] In this embodiment, a vertically arranged second guide rail is fixedly mounted on the second mounting plate, a second slider 506 is slidably mounted on the second guide rail, a second lead screw 505 is rotatably mounted on the second mounting plate, the second slider 506 and the second lead screw 505 are threadedly connected, a second motor 507 is fixedly mounted on the second mounting plate, and the output shaft of the second motor 507 is fixedly connected to one end of the second lead screw 505.

[0041] The second motor 507 drives the second lead screw 505 to rotate, and the second lead screw 505 drives the second slider 506 to slide vertically along the second guide rail.

[0042] In this embodiment, for ease of description and clarity, the movement direction of the first slider 503 is defined as the X-axis direction, and the movement direction of the second slider 506 is defined as the Z-axis direction. The second slider 506 can move along the Z-axis under the drive of the second motor 507 and the second lead screw 505 to pick up and place the connector 7, and it can also move along the X-axis under the drive of the first motor 504 and the first lead screw 502 to transfer the connector 7.

[0043] In this embodiment, the second slider 506 is fixedly connected to a vertically installed feeding cylinder 508, and the output end of the feeding cylinder 508 is equipped with a feeding gripper 509.

[0044] Specifically, the feeding gripper 509 is used to place the connector 7 to be cut into the positioning fixture 3, replacing manual feeding and saving time and effort.

[0045] In this embodiment, the upper surface of the mounting base 1 is also provided with a feeding mechanism 6. The feeding mechanism 6 includes a first feeding plate, a first feeding groove 601 on the first feeding plate, a vibratory feeder 605 at the feeding end of the first feeding groove 601, and a second feeding plate at the discharging end of the first feeding groove 601. The second feeding plate and the first feeding plate can be integrally formed. The second feeding plate is provided with a second feeding groove 602. The first feeding groove 601 and the second feeding groove 602 are connected. The width direction of both the first feeding groove 601 and the second feeding groove 602 can only accommodate one connector 7 to pass through.

[0046] One end of the second feeding trough 602 corresponds to the feeding gripper 509, and the other end of the second feeding trough 602 is fixedly provided with a second cylinder 603. The output end of the second cylinder 603 is fixedly connected to a push plate 604. The push plate 604 slides with the second feeding trough 602 and abuts against the side wall of the connector 7.

[0047] The vibratory feeder 605 is used to arrange the connectors 7 in a uniform manner according to a set posture for output. The vibratory feeder 605 preferably uses a mature product model from the existing technology, and its structure will not be described in detail here. The arranged connectors 7 pass through the first feeding groove 601 and then enter the second feeding groove 602. The second cylinder 603 extends, driving the push plate 604 to move and push the connectors 7 to a position that the feeding claw 509 can grasp. Then, the second cylinder 603 retracts, driving the push plate 604 back to its original position.

[0048] In this embodiment, a third motor is fixedly installed on the lower surface of the mounting base 1. The output shaft of the third motor is connected to the rotation shaft of the turntable 2. The third motor is used to drive the turntable 2 to rotate.

[0049] In this embodiment, during use, bulk connectors 7 with material heads 701 are placed into a vibratory feeder 605. The vibratory feeder 605 arranges the connectors 7 to be cut into the first feeding groove 601. After the arranged connectors 7 pass through the first feeding groove 601, the second cylinder 603 extends, driving the push plate 604 to move and push the connectors 7 to a position where the feeding gripper 509 can grasp them. The second motor 507 drives the second lead screw 505 to rotate, and the second lead screw 505 drives the second slider 500... 6. As the second slider 506 moves downward, it drives the loading gripper 509 to pick up the connector 7. Then, the first motor 504 drives the first lead screw 502 to rotate. The first lead screw 502 drives the first slider 503 to move horizontally, which in turn drives the loading gripper 509 to place the connector 7 into the positioning fixture 3. After the turntable 2 moves the positioning fixture 3 and the connector 7 to the cutting position of the shearing mechanism 4, the first cylinder 402 extends, driving the cutter 403 to move downward and cut off the material ends 701 at both ends of the connector 7. The connector 7 with the material ends 701 cut off passes downward through the positioning cavity 301, the second through hole 201 and the first through hole 101 in sequence, and falls into the finished product box below the mounting base 1. The material ends 701 cut off at both ends pass through the third through hole 102 and the fourth through hole 202 in sequence, and finally fall into the waste bin. Repeating the above steps can continuously perform the cutting operation of the material ends 701 of the connector 7.
