[0025] Furthermore, a buffer block that slides vertically is slidably provided on the outer side of the pressing platform; an upper stop block that limits the upper stroke of the buffer block is fixedly provided on the upper end of the pressing platform above the buffer block, and a lower stop block that limits the lower stroke of the buffer block is fixedly provided on the lower end of the pressing platform below the buffer block.

[0026] An upper support is fixedly installed on the upper part of the outer side of the buffer block, and a lower support is fixedly installed on the lower part, with the upper support located above the lower support; a downward-facing rotary swing cylinder is mounted on the upper support, with the rotating end of the rotary swing cylinder located below the upper support; the upper end of the suction disc is rotatably mounted on the lower support and extends upward to connect with the rotating end of the rotary swing cylinder; the rotary swing cylinder drives the suction disc to form a 90° rotation angle;

Detailed Implementation

[0051] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0052] Please see Figure 1 As shown in Figure 12, the Ethernet cable harness 1 consists of a cable body 2 and a connector 3. The connector consists of terminals, a housing, and an internal C-shaped component 4. During assembly, each component needs to be assembled sequentially to form a complete connector. The internal C-shaped component 4 refers to the internal component of the connector, which is roughly C-shaped and assembled inside the connector.

[0053] Please see Figure 3 As shown, the Ethernet harness inner C-part feeding and crimping device of this application is mainly used to automatically crimp the inner C-part 4 to the Ethernet connection end that already has a half-shell in the previous process, so as to automatically crimp the inner C-part 4 to the connection end of the Ethernet harness, completing the entire process of automatic feeding, automatic material handling, automatic material transfer, and automatic crimping without manual operation. This application adopts the following structure for implementation: the feeding and crimping device includes a base 5, a vibratory feeder 6, a linear feeder 7, a material handling mechanism 8, a material transfer mechanism 9, an auxiliary clamp 10, and a crimping mechanism. The attached drawings of this application show an integrated feeding device and material handling mechanism, equipped with two sets of material handling, material transfer, and crimping equipment to improve the efficiency of equipment use and at the same time reduce the space occupied by the equipment.

[0054] The base 5 is arranged horizontally, and a horizontal assembly platform is provided above the base 5 to support the actuators in the entire pressing device. Specifically, the material handling mechanism 8, the material transfer mechanism 9, the auxiliary clamp 10, and the pressing mechanism are arranged above the base 5. The vibratory feeder 6 and the linear feeder 7 are located on one side of the base 5. The vibratory feeder 6 and the linear feeder 7 used in this application are common equipment, and their specific structures will not be described in detail here. Several inner C-pieces 4 are placed in the vibratory feeder 6. The vibration of the vibratory feeder 6 causes the inner C-pieces 4 to be discharged from the outlet of the vibratory feeder 6 in sequence. The inner C-pieces 4 are discharged with their openings facing downwards. The outlet of the vibratory feeder 6 is connected to the inlet of the linear feeder 7. The inner C-pieces 4 discharged from the vibratory feeder 6 enter the linear feeder 7 for feeding. The linear feeder 7 is used to make the inner C-pieces 4 connect end to end and arrange them in a straight line for feeding.

[0055] Please see Figure 8As shown, in this application, the material handling mechanism 8 includes a receiving station 11, two waiting stations 12 located on both sides of the receiving station 11, and a material handling device that provides material handling power. The receiving station is a working position for receiving inner C parts, and the waiting station is a working position waiting to move the inner C parts from the station. The linear feeder 7 feeds the inner C parts 4 into the receiving station 11, and the material handling device moves the inner C parts 4 from the receiving station 11 to the waiting station 12. That is, by moving the inner C parts 4 from the receiving station 11 to one side of the waiting station 12 or to the other side of the waiting station 12, the material handling mechanism 8 can realize left and right material handling.

[0056] In this application, the auxiliary clamp 10 holds the Ethernet cable harness, exposing the snap-fit ​​position of the inner C-piece 4 at the top of the Ethernet cable harness connector; this allows the inner C-piece 4 to be pressed into the snap-fit ​​position from top to bottom. The auxiliary clamp 10 holds the Ethernet cable harness, maintaining its stability during the pressing process of the inner C-piece 4, preventing it from flipping, shifting, or tilting, thus ensuring the accuracy of the snap-fit ​​of the inner C-piece 4 into the snap-fit ​​position.

[0057] In this application, the material transfer mechanism 9 picks up the inner C component 4 of the station to be transferred 12 and moves the inner C component 4 to directly above the snap-fit ​​position of the inner C component 4 at the Ethernet harness connection end; the pressing mechanism then moves the inner C component 4, which is directly above the snap-fit ​​position of the inner C component 4 at the Ethernet harness connection end, downward and presses it so that the inner C component 4 is snapped into the snap-fit ​​position at the Ethernet harness connection end.

[0058] Please see Figure 5-8 As shown, in this application, the material handling mechanism 8 includes a material handling base 13 fixedly mounted above the base 5. The material handling base 13 is fixedly mounted horizontally above the base 5. A vertically arranged material handling support plate 14 is fixedly mounted on one side above the material handling base 13. A horizontally arranged material handling platform 15 is fixedly mounted on one side above the material handling support plate 14. The material handling platform 15 is located above the material handling base 13, and an assembly space 16 is formed between the lower part of the material handling platform 15, the upper part of the material handling base 13, and one side of the material handling support plate 14. In order to ensure the firmness of the connection between the material handling support plate 14 and the material handling base 13, support blocks 17 are fixedly mounted on both sides of the material handling support plate 14 and the material handling base 13, respectively.

[0059] Specifically, the material handling platform 15 is provided with a material handling channel 18 that runs through the upper and lower surfaces of the material handling platform 15. A material handling block 19 is provided within the material handling channel 18, and the material handling block 19 moves back and forth horizontally within the material handling channel 18. A material handling driver 20 is provided in the assembly space 16 to drive the material handling block 19 to move back and forth horizontally within the material handling channel 18. The material handling driver 20 can realize bidirectional horizontal movement of the material handling block 19, and automatically moves the material handling block 19 carrying the inner C part 4 to the corresponding workstation according to the material handling requirements.

[0060] Specifically, a receiving groove 21 for receiving inner C-piece 4 is provided in the middle of the outer side of the material handling platform 15. A protruding rib 22 extending along the traveling direction of the inner C-piece 4 is provided in the middle of the receiving groove 21. The height of the protruding rib 22 is lower than the opening of the receiving groove 21. Guide grooves are formed on both sides of the protruding rib, with the bottom of one guide groove higher than the bottom of the other. The middle opening of the inner C-piece 4 passes through the protruding rib section. The larger end of the inner C-piece 4 passes through the lower bottom of the guide groove, and the smaller end passes through the higher bottom of the guide groove. This ensures that the inner C-piece 4 enters the receiving groove 21 stably and prevents inner C-pieces with different orientations from entering the receiving groove 21, ensuring accurate feeding of the inner C-piece. A baffle 32 is installed above the receiving groove 21, covering the upper part of the receiving groove 21. The space between the receiving groove 21 and the baffle is only large enough for the inner C-piece to pass through.

[0061] Specifically, the middle position of the material handling channel 18 facing the receiving trough 21 is the receiving station 11; the two ends of the material handling channel 18 are the left and right waiting stations 12; when receiving material, the material handling block 19 is in the receiving station 11 to receive the inner C part 4 in the receiving trough 21; when moving material, the material handling block 19 carries the inner C part 4 and moves it to the left or right waiting station. The middle part of the upper surface of the material handling block 19 is the receiving chamber 25, which is lower than the receiving trough 21. The size of the receiving chamber 25 is adapted to the inner C part 4 so that the inner C part 4 can slide into the receiving chamber 25; when receiving material, the receiving chamber 25 is connected to the receiving trough 21, and the inner C part 4 in the receiving trough 21 enters the receiving chamber 25; when moving material, the receiving chamber 25 is staggered from the receiving trough 21, and the end of the material handling block 19 forms a barrier to the receiving trough 21 to prevent the inner C part 4 in the receiving trough 21 from being discharged. An infrared transmitter 26 is mounted on one side of the material handling block 19, and an infrared receiver 27 is mounted on the other side. A detection channel 28 is formed on the upper surface of the material handling block 19 along its moving direction. The middle of the detection channel 28 communicates with the receiving bin 25. When the inner C part 4 is in the receiving bin 25, a portion of the inner C part 4 is in the detection channel 28. The infrared transmitter 26 and the infrared receiver 27 are located at opposite ends of the detection channel 28. The infrared light generated by the infrared transmitter 26 passes through the detection channel 28 and is received by the infrared receiver 27. During operation... During the process, when inner component 4 enters the receiving bin 25, some inner component 4 is in the detection channel 28. The infrared light emitted by the infrared transmitter 26 is blocked by the inner component 4, and the infrared receiver 27 cannot receive the infrared light. This indicates that the inner component 4 is in the receiving bin 25, and the material handling block 19 starts the material handling action, moving the inner component 4 to the waiting station 12. When the infrared receiver 27 receives the infrared light, it indicates that the inner component 4 has been removed and there is no inner component 4 in the receiving bin 25. The material handling block 19 then starts moving to the receiving station 11. Infrared light is used to detect the presence or absence of inner component 4. Existing technologies such as ultrasonic waves can also be used.

[0062] In this application, the material handling actuator 20 includes a first sliding cylinder 29 and a second sliding cylinder 30 arranged horizontally in the assembly space 16. The second sliding cylinder 30 is located above the first sliding cylinder 29. The lower end of the material handling block 19 is fixedly mounted on the slide 31 of the second sliding cylinder 30, and the upper end of the material handling block 19 extends into the material handling channel 18 from below. The body of the first sliding cylinder 29 is fixedly mounted on the side of the material handling support plate 14, and the body of the second sliding cylinder 30 is fixedly mounted on the slide 33 of the first sliding cylinder 29. The extension and retraction driving directions of the first sliding cylinder 29 and the second sliding cylinder 30 are arranged in opposite directions, that is, the extension and retraction driving directions of the first sliding cylinder 29 and the second sliding cylinder 30 are opposite. One faces left, the other right; the operation of the first slide cylinder 29 drives the movement of the second slide cylinder 30; when the material handling block 19 is in the receiving position, both the first slide cylinder 29 and the second slide cylinder 30 are in a retracted state. When a material handling action is required, the extension of the first slide cylinder 29 can move the material handling block 19 from the receiving station 11 to a waiting station. After the inner C part 4 on the waiting station is removed, the first slide cylinder 29 retracts back to the receiving station 11 to receive the material; the second slide cylinder 30 then extends, which can move the material handling block 19 from the receiving station 11 to another waiting station. After the inner C part 4 on the waiting station is removed, the second slide cylinder 30 retracts back to the receiving station, and so on. The material handling driver 20 requires two slide cylinders to form a combination, which is convenient for operation and control, has a simple structure and is easy to assemble, and reduces costs. Of course, the material handling driver 20 can also be implemented using other reciprocating linear drive mechanisms, such as lead screw motors, sliders, etc.

[0063] Please see Figure 9 , 10 As shown, in this application, two material transfer mechanisms 9 are arranged, one for transferring material to the left and the other for transferring material to the right. Each material transfer mechanism 9 is used to transfer the inner C part 4 at a corresponding workstation. Specifically, the material transfer mechanism 9 includes a material transfer bracket 34 fixedly mounted above the base 5. The material transfer bracket 34 is composed of two vertically arranged base frames 35 fixedly mounted above the base 5 and a horizontal frame 36 fixedly above the two base frames 35. A horizontally arranged material transfer track 37 is fixedly provided on one side of the horizontal frame 36 of the material transfer bracket 34, a material transfer stage 38 is slidably mounted on the material transfer track 37, and a material transfer driver 39 mounted on the material transfer bracket 34 to drive the material transfer stage 38 to move back and forth on the material transfer track 37. In this application, the material transfer driver 39 is implemented by a cylinder. The material transfer driver 39 is mounted on one end of the material transfer track 37 through a mounting base. The extension and retraction of the material transfer driver 39 can drive the material transfer stage 38 to move back and forth on the material transfer track 37.

[0064] In this application, two crimping mechanisms are also provided, one crimping mechanism is correspondingly mounted on one transfer mechanism 9; the transfer mechanism 9 and the crimping mechanism are combined together, when the transfer mechanism 9 moves the inner C part 4 to the crimping position, the crimping mechanism will crimp the inner C part 4 downwards to crimp the inner C part 4 to the snap-fit ​​position of the wire harness; specifically, the crimping mechanism includes a crimping platform 40 mounted on one side of the transfer table 38, a sliding structure between the crimping platform 40 and the transfer table 38 for the crimping platform 40 to form a reciprocating motion in the vertical direction, the sliding structure is realized by the cooperation of the slide rail and the slider, and a crimping driver 41 mounted on the transfer table 38 to drive the crimping platform 40 to form a reciprocating motion in the vertical direction; the crimping driver 41 can be a cylinder, a hydraulic cylinder, an electric cylinder, etc.

[0065] In this application, the material transfer mechanism 9 also includes a suction plate 42 mounted on the pressing platform 40 to pick up the inner C-part 4 at the transfer station. The suction plate 42 uses an adsorption method. Specifically, the suction plate 42 has a cavity inside, the suction head of the suction plate 42 communicates with the cavity, and a connecting pipe communicates with the inner cavity of the suction plate 42. By using an air extraction method, a negative pressure is created inside the suction plate 42 through the connecting pipe, thereby generating an adsorption force on the inner C-part 4 at the suction head, thus enabling the inner C-part 4 to be adsorbed.

[0066] In this application, a buffer block 43 that slides vertically is slidably disposed on the outside of the pressing platform 40; an upper stop block 44 that limits the upper stroke of the buffer block 43 is fixedly disposed on the upper end of the pressing platform 40 above the buffer block 43, and a lower stop block 45 that limits the lower stroke of the buffer block 43 is fixedly disposed on the lower end of the pressing platform 40 below the buffer block 43; the buffer block 43 moves up and down within the stroke between the upper and lower stop blocks; an upper support 46 is fixedly disposed on the upper part of the outside of the buffer block 43 and a lower support 47 is fixedly disposed on the lower part, with the upper support 46 located above the lower support 47; A downward-facing rotary swing cylinder 48 is mounted on the upper support 46, with the rotating end of the rotary swing cylinder 48 located below the upper support 46. The upper end of the suction plate 42 is rotatably mounted on the lower support 47 and extends upward to connect with the rotating end of the rotary swing cylinder 48. The rotary swing cylinder 48 can drive the suction plate 42 to rotate by 90°, thereby enabling the inner C part 4 to rotate by 90° to change the angle of the inner C part 4. For example, if the inner C part 4 in the station to be moved is at zero degrees, it will rotate 90 degrees to the position above the snap-fit ​​position after the change.

[0067] In this application, to achieve an elastic pressing action between the inner C-part 4 and the snap-fit ​​position during the crimping process, thus avoiding damage caused by rigid crimping, snap-fit ​​posts 49 are fixedly installed on the lower stop block and the buffer block 43, respectively. A tension spring 50 is assembled between the two snap-fit ​​posts 49. One end of the tension spring 50 hooks onto the snap-fit ​​post on the lower stop block, and the other end of the tension spring 50 hooks onto the snap-fit ​​post on the buffer block 43. When the buffer block 43 moves upward, the tension spring 50 generates a downward pulling force. When the inner C-part 4 is snapped into the snap-fit ​​position, the buffer block 43 tends to slide upward, but under the action of the tension spring, the inner C-part 4 is kept above the snap-fit ​​position. The inner C-part 4 can make adaptive adjustments and finally snap into the snap-fit ​​position of the wire harness.

[0068] Please see Figure 11 , 12 As shown in this application, the auxiliary clamp 10 includes a clamp base 51 fixedly mounted horizontally above the base 5; above the clamp base 51 are a clamping mechanism 52 for clamping the wire near the Ethernet cable harness connection end, a crimping worktable 53 for supporting the snap-fit ​​position of the inner C-piece 4 of the Ethernet cable harness connection end, and a pressing mechanism 54 for pressing the end of the Ethernet cable harness connection end onto the crimping worktable 53. The crimping worktable 53 is located between the clamping mechanism 52 and the pressing mechanism 54. The Ethernet cable harness connection end passes through the clamping mechanism 52, the crimping worktable 53, and the pressing mechanism 54 in sequence. The snap-fit ​​position of the inner C-piece 4 on the cable harness is above the crimping worktable 53. One end of the snap-fit ​​position is clamped by the clamping mechanism 52, and the other end is pressed by the pressing mechanism 54, thereby ensuring that the cable harness is stably clamped and will not flip, ensuring the reliability of the subsequent crimping quality.

[0069] Specifically, the wire clamping mechanism 52 includes a pair of jaws 55 and a jaw cylinder 56. The jaw cylinder 56 is mounted on the clamp base 51, and the pair of jaws 55 are mounted on the drive end of the jaw cylinder 56. The jaw cylinder drives the pair of jaws 55 to engage to generate clamping force, or to disengage to lose clamping force. The jaw cylinder and jaws use a common structure, which will not be described in detail here. As long as the clamping or releasing action of the wire harness can be achieved, it is acceptable. In order to ensure that the wire harness can be accurately aligned with the clamping position between the jaws, a support plate 57 is fixedly mounted on the body of the jaw cylinder. The support plate 57 extends upward to the jaws and a guide plate 58 is fixedly installed. A through guide hole 59 is opened on the guide plate 58 and the support plate 57. The size of the guide hole 59 is larger than the size of the wire harness. The guide hole 59 coincides with the position where the pair of jaws generate clamping force. The wire harness passes through the guide hole 59 and extends into the pair of jaws, and can be clamped quickly and accurately.

[0070] In this application, the clamping mechanism 54 includes a clamping block 60 and a clamping cylinder 61. The clamping cylinder 61 drives the clamping block 60 to move closer to the crimping worktable 53, cooperating with the crimping worktable 53 to generate a clamping force or move away from the crimping worktable 53 to release the clamping force. Specifically, the top surface of the crimping worktable 53 is a horizontal bearing surface 62. The top surface of the crimping worktable 53 near the wire clamping mechanism 52 is provided with an inclined surface 63 to guide the wire harness when it enters. The top surface of the crimping worktable 53 near the clamping mechanism 54 is provided with a stop surface 64, which is lower than the bearing surface 62. An extension platform 65 extending towards the stop surface is provided in the middle of the top surface of the crimping worktable 53 on the side of the stop surface 64. The two sides of the extension platform 65 are connected to the stop surface by curved surfaces. The clamping block 60 The clamping block 60 is L-shaped and rotated 90 degrees clockwise. The vertically downward end of the clamping block 60 is the clamping end. The clamping end of the clamping block 60 is provided with a locking groove 66 that is adapted to the shape of the end of the wire harness connection. The locking groove 66 and the extension platform cooperate to lock the end of the Ethernet wire harness connection above the extension platform between the locking groove and the extension platform. The inner side of the locking groove 66 is provided with a limiting surface 67 that limits the depth of the Ethernet wire harness connection into the locking groove. When the wire harness connection reaches the limiting surface, it means that the wire harness has been inserted into place. Specifically, a horizontally placed support platform 23 is fixed on the fixture base 51 by four pillars 68. The body of the clamping cylinder 61 is located below the support platform, and the telescopic end of the clamping cylinder 61 is located above the support platform. A vertically arranged carrier plate 24 is fixed on the support platform. A rail and a slider mounted on the rail are installed on the carrier plate 24. The clamping block 60 is fixedly mounted on the slider. Thus, by extending and retracting the clamping cylinder 61, the clamping block 60 can be driven to move up and down.

[0071] This application also proposes an Ethernet harness production line including the aforementioned inner C-component feeding and crimping device. In the Ethernet harness production line, the inner C-component feeding and crimping device is used to receive the harness (without inner C-components) from the previous process by an automatic feeding mechanism. The connecting end of the harness is automatically inserted into the clamping mechanism, and the end of the harness connecting end is crimped by a pressing mechanism, so that the crimping position of the inner C-component at the connecting end faces the orientation. The inner C-component enters the receiving bin of the material handling block through a vibratory feeder and a linear feeder. The material handling mechanism transports the inner C-component to the station to be moved, and moves it to directly above the crimping position by a material handling mechanism, with the opening of the inner C-component facing the crimping position. Then, the crimping mechanism moves downward to crimp the inner C-component into the crimping position of the harness. After the crimping work is completed, under the action of the automatic harness feeding mechanism, the inner C-component exits the feeding and crimping device and is sent to the next process. The entire feeding and crimping production process does not require manual intervention, realizing the production of Ethernet harnesses.
