Description

Technical Field

[0001] This application relates to the field of terminal processing, and in particular to a terminal crimping device. Background Technology

[0002] Terminals are accessories used to achieve electrical connections. Some terminals, due to high strength requirements, are generally manufactured using cold forging. These terminals need to be individually secured to the wire harness using a terminal crimping device.

[0003] Currently, existing terminal crimping devices include a base, a vibratory feeder, a vibratory conveyor, a positioning mechanism, and a crimping mechanism. During operation, the vibratory feeder feeds the terminals sequentially to the vibratory conveyor, which then transports the terminals to the positioning mechanism to position the terminals and wire harnesses. Finally, the crimping mechanism crimps the terminals and wire harnesses together to secure them.

[0004] However, as Figure 1 As shown, during the terminal conveying process of the vibrating conveyor, partial overlap can easily occur between any adjacent terminals. When the preceding terminal is crimped, it will force the position of the following terminal to deviate, affecting the positioning of the following terminal and potentially affecting the crimping effect between the following terminal and the wire harness. Therefore, improvements are needed. Summary of the Invention

[0005] To improve the crimping effect between terminals and wire harnesses, this application provides a terminal crimping device.

[0006] The terminal crimping device provided in this application adopts the following technical solution: A terminal crimping device includes a base, a vibrating conveyor, and a separating conveying mechanism. The base has a conveying channel, and the vibrating conveyor is connected to the input end of the conveying channel. The separating conveying mechanism is located near the output end of the conveying channel. The separating conveying mechanism includes a connecting block, a first driving component, and a separating claw. The connecting block is connected to the power output end of the first driving component, and the separating claw is rotatably connected to the connecting block. The first driving component drives the separating claw to move along the conveying channel based on the displacement change of the separating claw.

[0007] By adopting the above technical solution, in actual operation, when the vibrating conveyor transports terminals into the conveying channel, and two adjacent and overlapping terminals pass through the separating claw, the separating claw is lifted, and the non-connecting end of the separating claw abuts against the terminal in front under the action of gravity. At this time, the first driving component drives the separating claw to move along the conveying channel according to the displacement change of the separating claw, so that the separating claw drives the abutting terminals to move faster into the positioning mechanism, thereby realizing the separation of adjacent overlapping terminals, ensuring that the terminals are crimped with the wire harness one by one, and thus improving the crimping effect between the terminals and the wire harness.

[0008] Furthermore, when the terminal is crimped with the wire harness, the release claw abuts against the other end of the crimped part of the terminal, thereby limiting the terminal from lifting up as much as possible and further improving the crimping effect between the terminal and the wire harness.

[0009] Preferably, the conveying channel includes a closed section and an open section, the closed section being connected to the open section, and the closed section being connected to the vibrating conveyor.

[0010] By adopting the above technical solution, and by setting up a closed section and an open section, with the base located on the upper side of the open section, it is easier to remove the material after crimping, thereby improving the crimping efficiency of the terminals.

[0011] Preferably, the base has a clearance groove at one end of the closed section near the open section, and the clearance groove is connected to the closed section.

[0012] By adopting the above technical solution and setting a clearance groove, the separating claw abuts against the terminal before the terminal enters the open section, which improves the stability of the separating conveying mechanism driving the terminal to the positioning mechanism; in addition, the distance between the terminal being crimped by the separating claw and the next terminal to be crimped is longer, so as to facilitate the continuous operation of the terminal crimping device.

[0013] Preferably, the first driving component includes a first driving member, a slide rail, and a slider. The first driving member and the slide rail are both disposed on the base. The slider is slidably connected to the slide rail. The power output end of the first driving member is connected to the connecting block, and the connecting block is disposed on the slider.

[0014] By adopting the above technical solution, and by setting the first driving component, slide rail and slider, the movement of the connecting block is made more stable, thereby making the separation claw drive the terminal to move more stably, and thus improving the crimping effect between the terminal and the wire harness.

[0015] Preferably, the separating claw has a first inclined surface on the side away from its own rotation and close to the conveying channel, and the first inclined surface is used to abut against the terminal.

[0016] By adopting the above technical solution, and by setting a first inclined surface, after the terminal passes through the separation claw, the first inclined surface abuts against the terminal, thereby increasing the contact area between the separation claw and the terminal, and thus improving the stability of the separation claw driving the terminal to move.

[0017] Preferably, the separating claw has a second inclined surface on the side away from its own rotation and away from the conveying channel, and the second inclined surface is used to abut against the terminal.

[0018] By adopting the above technical solution, and by setting a second inclined surface that abuts against the terminal, the stability of the separation claw driving the terminal to move is further improved, thereby improving the crimping effect between the terminal and the wire harness.

[0019] Preferably, it further includes a positioning mechanism, the positioning mechanism including a first positioning element, the first positioning element being disposed at the end of the open section away from the closed section, the first positioning element having a positioning groove.

[0020] By adopting the above technical solution, by setting the first positioning element, the separation claw drives the crimping part of the terminal into the positioning groove, so as to facilitate the positioning and crimping of the terminal and the wire harness, thereby improving the crimping effect of the terminal and the wire harness.

[0021] Preferably, the positioning mechanism further includes two second positioning members and a second driving member. The two second positioning members are sealed on the side of the positioning groove away from the open section. A through hole communicating with the positioning groove is formed between the two second positioning members. The two second positioning members are disposed on the second driving member, and the second driving member drives the two second positioning members to move closer to or further away from each other.

[0022] By adopting the above technical solution, by setting a second positioning member and a second driving member, the second driving member drives the two second positioning members to move closer to each other, so that the two positioning members form wire-passing holes, so as to facilitate the positioning and passing of the wire harness to the crimping part of the terminal; and the two second positioning members are sealed in the positioning groove, so that the terminal abuts against the two positioning members, further ensuring the crimping position of the terminal, thereby improving the crimping effect between the terminal and the wire harness.

[0023] Preferably, the wire hole is narrowed on the side away from the positioning groove and turned towards the other side.

[0024] By adopting the above technical solution, the wire hole is set with its diameter reduced from the side away from the positioning groove to the other side, and the wire hole guides the wire harness, allowing it to be threaded more accurately and efficiently to the crimping part of the terminal.

[0025] Preferably, it also includes two shielding plates, which are respectively connected to the two second positioning members. When the two second positioning members are close to each other, the two shielding plates block the open section.

[0026] By adopting the above technical solution, and by setting two baffles, when the second driving member drives the two second positioning members to move closer to each other, the two baffles move closer to each other to block the upper side of the open section, further limiting the lifting of the terminal during crimping, thereby improving the crimping effect between the terminal and the wire harness.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. Terminals are conveyed to the conveyor channel via a vibrating conveyor. When two adjacent and overlapping terminals pass through the separating claw, the separating claw is lifted, and the non-connecting end of the separating claw abuts against the terminal in front under the action of gravity. At this time, the first drive assembly drives the separating claw to move along the conveyor channel according to the displacement change of the separating claw, so that the separating claw drives the abutting terminal to move into the positioning mechanism, thereby realizing the separation of adjacent and overlapping terminals, ensuring that the terminals are crimped with the wire harness one by one, and thus improving the crimping effect between the terminals and the wire harness; 2. By setting a second positioning member and a second driving member, the second driving member drives the two second positioning members to move closer to each other, so that the two positioning members form wire-passing holes, so that the wire harness can be positioned and passed to the crimping part of the terminal; and the two second positioning members are sealed in the positioning groove, so that the terminal abuts against the two positioning members, further ensuring the crimping position of the terminal, thereby improving the crimping effect between the terminal and the wire harness. 3. By setting two baffles, when the second driving member drives the two second positioning members to move closer to each other, the two baffles move closer to each other to block the upper side of the open section, further limiting the lifting of the terminal during crimping, thereby improving the crimping effect between the terminal and the wire harness.

[0030] The following is in conjunction with the appendix Figure 2-9 This application will be described in further detail.

[0031] This application discloses a terminal crimping device.

[0032] Reference Figure 2 and Figure 3 The terminal crimping device includes a base 1, a vibrating conveyor 2, a separating conveying mechanism 3, a positioning mechanism 4, and a crimping mechanism 5. The vibrating conveyor 2 is used to transport terminals 6, the separating conveying mechanism 3 is used to separate and transport terminals 6 to the positioning mechanism 4, and the crimping mechanism 5 is used to fix terminals 6 to the wire harness. Terminal 6 includes an integral connecting base 61 and a crimping part 62.

[0033] Reference Figure 4 and Figure 5 Specifically, the base 1 is provided with a conveying channel 11, the shape of which is adapted to the terminal 6. The input end of the conveying channel 11 is connected to the vibrating conveyor 2, and the output end is connected to the positioning mechanism 4. The conveying direction of the conveying channel 11 is the same as that of the vibrating conveyor 2.

[0034] Reference Figure 4 and Figure 6The separating conveying mechanism 3 is located near the output end of the conveying channel 11. Specifically, the separating conveying mechanism 3 includes a connecting block 31, a first driving assembly 32, and a separating claw 33. The connecting block 31 is connected to the power output end of the first driving assembly 32, which is fixedly connected to the base 1. One end of the separating claw 33 is rotatably connected to the connecting block 31, and the other end extends into the conveying channel 11 under the action of gravity. The first driving assembly 32 drives the separating claw 33 to move along the conveying channel 11 based on the displacement change of the separating claw 33. The displacement change is the change in the state of the separating claw 33 after it is lifted by the crimping part 62 of the terminal 6 and abuts against the base 61 of the terminal 6. For example, when the separating claw 33 moves from one end of the base 61 to the other end, the displacement change occurs in the horizontal direction or in the direction of gravity. In this embodiment, the displacement change of the separating claw 33 is acquired by a displacement monitor, which is controlled and connected to the first drive component 32. When the displacement monitor detects that the separating claw 33 has undergone the aforementioned displacement change, it sends a control command to the first drive component 321, causing the first drive component 321 to provide forward acceleration power to the separating claw 33 based on the control command. Of course, the displacement change of the separating claw 33 can also be detected by other detection devices, and this application does not limit it.

[0035] During the operation of the terminal crimping device, terminals 6 are fed one by one to the vibratory conveyor 2 via a vibratory plate. The vibratory conveyor 2 continuously conveys the terminals 6 into the conveying channel 11. When two adjacent and overlapping terminals 6 pass through the separating claw 33 in the conveying channel 11, the separating claw 33 is lifted and the non-connecting end abuts against the base 61 and crimping part 62 of the terminal 6 in front under the action of gravity. At this time, the displacement controller transmits the detection signal of the displacement change of the separating claw 33 to the first drive component 32. The first drive component 32 operates, driving the separating claw 33 to move along the conveying channel 11, so that the separating claw 33 drives the abutting terminal 6 to move into the positioning mechanism 4, thereby realizing the separation of adjacent and overlapping terminals 6, ensuring that the terminals 6 are crimped with the wire harness one by one, and thus improving the crimping effect between the terminals 6 and the wire harness.

[0036] Furthermore, when the crimping mechanism 5 crimps the crimping part 62 of the terminal 6 with the wire harness, the non-connecting end of the separating claw 33 abuts against the base 61 of the terminal 6, which minimizes the risk of the terminal 6 lifting up during the crimping process and further improves the crimping effect between the terminal 6 and the wire harness.

[0037] The conveying channel 11 includes a closed section 111 and an open section 112. One end of the closed section 111 is connected to the vibrating conveyor 2, and the other end is connected to the open section 112. The base 1 is positioned openly on the upper side of the open section 112 to allow the separating claw 33 to extend into the conveying channel 11, minimizing interference. Simultaneously, the open section 112 facilitates material removal after crimping, thereby improving the crimping efficiency of the terminals 6.

[0038] Furthermore, the base 1 has a clearance groove 12 at one end of the closed section 111 near the open section 112. The clearance groove 12 is connected to the closed section 111, so that the separating claw 33 can abut against the terminal 6 before the terminal 6 enters the open section 112, thereby improving the stability of the separating conveying mechanism 3 driving the terminal 6 to the positioning mechanism 4. In addition, the distance between the terminal 6 being crimped by the separating claw 33 and the next terminal 6 to be crimped is longer, so as to facilitate the continuous operation of the terminal crimping device.

[0039] Specifically, the first drive assembly 32 includes a first drive member 321, a slide rail 322, and a slider 323. The first drive member 321 is fixedly connected to the base 1, and the power output end of the first drive member 321 is fixedly connected to the connecting block 31. In this embodiment, the first drive member 321 is a cylinder; in other embodiments, it can also be an electric push rod, a hydraulic cylinder, etc. The slide rail 322 is fixedly connected to the base 1, and the slider 323 is slidably connected to the slide rail 322. The connecting block 31 is fixedly connected to the slider 323, which improves the stability of the movement of the connecting block 31, thereby improving the stability of the separation claw 33 driving the terminal 6 to move, and further improving the crimping effect between the terminal 6 and the wire harness.

[0040] Reference Figure 6 and Figure 7 Furthermore, a first inclined surface 331 is provided on the side of the separating claw 33 away from its own rotation and close to the conveying channel 11. The first inclined surface 331 is inclined towards the side of the separating claw 33 away from its rotation. When the pressing part 62 lifts the separating claw 33, the first inclined surface 331 abuts against the base 61, which increases the contact area between the separating claw 33 and the terminal 6, thereby improving the stability of the separating claw 33 in driving the terminal 6 to move.

[0041] Furthermore, a second inclined surface 332 is provided on the side of the separating claw 33 away from its own rotation and away from the conveying channel 11. The second inclined surface 332 is inclined towards the side of the separating claw 33 away from its rotation and abuts against one end of the crimping part 62. By cooperating with the first inclined surface 331 and the second inclined surface 332, the stability of the separation claw 33 driving the terminal 6 to move is ensured as much as possible, thereby improving the crimping effect between the terminal 6 and the wire harness.

[0042] Reference Figure 4 and Figure 8 Specifically, the positioning mechanism 4 includes a first positioning member 41, which is fixedly connected to the base 1 and located at the end of the open section 112 away from the closed section 111. The upper end of the first positioning member 41 is provided with a positioning groove 411, which is used for positioning and placing the crimping part 62 to facilitate the crimping of the terminal 6 with the wire harness, thereby improving the crimping effect between the terminal 6 and the wire harness.

[0043] Furthermore, the positioning mechanism 4 also includes two second positioning elements 42 and a second driving element 43. Both second positioning elements 42 are fixedly connected to the second driving element 43, which is fixedly connected to the base 1. The second driving element 43 is a gripper cylinder that drives the two second positioning elements 42 to move closer or further apart. When the second driving element 43 drives the two second positioning elements 42 to abut against each other, a wire-passing hole 44 is formed between the two second positioning elements 42. The wire-passing hole 44 communicates with the positioning groove 411 to facilitate the positioning and passing of the wire harness to the crimping portion 62 of the terminal 6.

[0044] Furthermore, the two positioning members are sealed in the positioning groove 411. When the separating claw 33 drives the terminal 6 to move to the positioning groove 411, the crimping part 62 abuts against the two second positioning members 42 to restrict the movement of the terminal 6, ensure the crimping position of the crimping part 62 and the wire harness, and also make the terminal 6 more stably positioned in the positioning groove 411, thereby improving the crimping effect between the terminal 6 and the wire harness.

[0045] The wire hole 44 is narrowed on the side away from the positioning groove 411 and faces the other side. The wire hole 44 guides the wire harness and allows it to be threaded more accurately and efficiently into the crimping part 62 of the terminal 6.

[0046] Furthermore, the positioning mechanism 4 also includes two baffles 45, which are fixedly connected to the two second positioning members 42 respectively. When the two second positioning members 42 are close to each other, the two baffles 45 block the upper side of the open section 112. It should be noted that the distance between the two baffles 45 is less than the diameter of the crimping part 62, and there are gaps between both sides of the separating claw 33 and the two baffles 45, so that the two baffles 45 can restrict the next terminal 6 to be crimped from entering the open section 112.

[0047] In actual operation, when the separating claw 33 drives the terminal 6 to move to the open section 112, the second driving member 43 drives the two second positioning members 42 to abut against each other, and the two baffles 45 to move closer to each other, so that the separating claw 33 can more stably drive the crimping part 62 into the positioning groove 411. After that, the crimping part 62 abuts against the two second positioning members 42, the first driving member 321 stops working, the crimping mechanism 5 crimps the crimping part 62 and the wire harness, the separating claw 33 abuts against the base 61, and the two baffles 45 restrict the base 61 from tilting up, thereby improving the crimping effect between the terminal 6 and the wire harness. At the same time, the end of the two baffles 45 away from the positioning groove 411 restricts the next terminal 6 to be crimped from entering the open section 112, so as to control the terminal crimping device to crimp the terminals 6 one by one continuously.

[0048] Reference Figure 2 and Figure 9Specifically, the crimping mechanism 5 includes a crimping head 51 and a second drive assembly 52. ​​The crimping head 51 is fixedly connected to the power output end of the second drive assembly 52, and the second drive assembly 52 is fixedly connected to the base 1. The second drive assembly 52 is an existing structure that drives the crimping head 51 to move in the vertical direction so that the crimping head 51 moves into the positioning groove 411 to crimp the crimping part 62 and the wire harness.

[0049] It should be noted that after the terminal 6 and the wire harness are crimped together by the crimp connector 51, the first drive assembly 32 can be controlled by the sensor to drive the separation claw 33 to reset, so as to transport the next terminal 6 to be crimped to the positioning mechanism 4.

[0050] The implementation principle of this embodiment is as follows: During the operation of the terminal crimping device, terminals 6 are fed one by one to the vibratory conveyor 2 via a vibratory plate. The vibratory conveyor 2 continuously conveys terminals 6 into the conveying channel 11. When two adjacent and overlapping terminals 6 pass through the separating claw 33 in the conveying channel 11, the separating claw 33 is lifted and the non-connecting end abuts against the base 61 and crimping part 62 of the terminal 6 in front under the action of gravity. At this time, the displacement controller transmits the detection signal of the displacement change of the separating claw 33 to the first drive component 32. The first drive component 32 operates, driving the separating claw 33 to move along the conveying channel 11, so that the separating claw 33 drives the abutting terminals 6 to move into the positioning mechanism 4, thereby realizing the separation of adjacent and overlapping terminals 6, so as to ensure that terminals 6 are crimped with the wire harness one by one, thereby improving the crimping effect between terminals 6 and wire harness.

[0051] Furthermore, when the crimping mechanism 5 crimps the crimping part 62 of the terminal 6 with the wire harness, the non-connecting end of the separating claw 33 abuts against the base 61 of the terminal 6, which minimizes the risk of the terminal 6 lifting up during the crimping process and further improves the crimping effect between the terminal 6 and the wire harness.

[0052] Specifically, when the separating claw 33 drives the terminal 6 from the closed section 111 to the open section 112, the second driving member 43 drives the two second positioning members 42 to abut against each other, and the two baffles 45 to move closer to each other, so that the separating claw 33 can more stably drive the crimping part 62 into the positioning groove 411. When the crimping part 62 abuts against the two second positioning members 42, the first driving member 321 stops working, and the second driving assembly 52 drives the crimping head 51 to move into the positioning groove 411 to crimp the crimping part 62 to the wire harness. Afterwards, the first driving member 321 drives the separating claw 33 to move to the closed section 111 to move the next terminal 6 to be crimped, and so on, to continuously crimp the terminal 6.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
