Description

Technical Field

[0001] This utility model relates to the technical field of terminal connector assembly devices, and specifically to a connector dotting assembly device. Background Technology

[0002] In the field of connector manufacturing, such as Figure 7 As shown, the terminal connector 9 mainly uses a dotting assembly process to fix the pin 90 and the socket 91. Traditional dotting assembly is mainly done manually, which is slow. To address the above problem, application number CN202310379467.0 discloses a connector assembly device, including a pressing base, a pressing pin, a pressing spring, and a pressing upper plate. The pressing pin is mounted on the pressing base. The pressing upper plate is slidably sleeved on the pressing pin and has a movable cavity between it and the pressing base. The two ends of the pressing spring are respectively connected to the pressing base and the pressing upper plate. The pressing upper plate is provided with at least two dotting components evenly spaced around the circumference of the pressing pin. The dotting components are slidably connected to the pressing upper plate along the radial direction of the pressing pin. As the pressing upper plate moves downward, the dotting components can slide in the direction close to the pressing pin. When the press-fit upper plate moves downward, the press-fit pin presses against the inner ring of the cover, causing the inner ring of the cover to deform and press against the inner wall of the hole sleeve. At the same time, the dotting assembly clamps the outer peripheral wall of the cover, causing the outer peripheral wall of the cover to press against the outer peripheral wall of the hole sleeve. This achieves a double interference fit between the cover and the hole sleeve, strengthens the connection strength between the cover and the hole sleeve in the terminal connector, and reduces the probability of the cover detaching from the hole sleeve.

[0003] However, the aforementioned terminal connector assembly device still has the following problems: 1. The existing terminal connector assembly device performs pressing and dotting simultaneously, which can easily lead to terminal connector misalignment, resulting in deviation of the dotting position, or deformation of the terminal connector, affecting the dotting quality; 2. The pressing spring of the existing terminal connector assembly device needs to bear both pressing force and reset function at the same time, which can easily lead to fatigue failure and jamming, affecting the efficiency of subsequent dotting processing; 3. The existing terminal connector assembly device requires lifting, dotting processing, unloading, and changing materials of the terminal connector material before the dotting processing of new terminal connectors can be carried out. The dotting processing steps are numerous, affecting the efficiency of dotting processing. Utility Model Content

[0021] Compared with the prior art, the connector dotting assembly device provided in this utility model embodiment has at least one of the following technical effects:

[0022] 1. This utility model innovatively performs a pre-positioning and then marking action on a terminal connector by setting a push rod with a pushing part, a slider with a positioning surface, and a marking pin. When the pushing part performs the marking action, it controls the slider with the positioning surface to first position and fix the outer wall of the terminal connector, ensuring that the center of the terminal connector is aligned with the central axis, guaranteeing the position of the terminal connector and preventing displacement. Then, after the slider is pushed into place, the pushing part pushes the marking pin out of the slider to perform the marking process on the positioned terminal connector, ensuring the quality of the terminal connector marking assembly. Furthermore, when processing petal-shaped terminal connectors, this pre-positioning and clamping before marking ensures uniform stress on the petal structure, solving the problem of petal breakage or deformation caused by traditional marking devices.

[0023] 2. By setting a reset part for resetting the slider and the dotting pin after the dotting process is completed, the installation of the pressure spring is saved, and the impact of the pressure spring failure on subsequent dotting processes is reduced, thus ensuring the normal operation and processing efficiency of the connector dotting assembly device.

[0024] 3. By setting a channel for the terminal connector to pass through and a central through hole through the channel, after the terminal connector is moved into place, a pressing mechanism is set up to achieve the positional stability of the terminal connector on the vertical axis and the horizontal position, so that subsequent fixed dotting processing can be carried out, saving steps and improving the quality and efficiency of subsequent dotting.

[0036] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0037] For examples, see the appendix. Figures 1-10 A connector dotting assembly device 1 includes a base 2 and a pressing mechanism 3 that can move up and down on the base 2. The base 2 is provided with a channel 20 for terminal connectors 9 to pass through and a central through hole 21 through the channel 20. The central through hole 21 is located above the channel 20. The base 2 is provided with at least two vertical channels 22 and at least two horizontal channels 23. The vertical channels 22 are respectively arranged on the horizontal channels 23 and pass through the horizontal channels 23 to the outside. The horizontal channels 23 are connected to the channel 20. The channel 20 is used for the passage of material channels composed of multiple terminal connectors 9. When there are two vertical channels 22, the two vertical channels 22 are arranged on the base on the vertical side of the channel 20 in a mirror-image manner. When there are more than two vertical channels 22, the multiple vertical channels 22 are evenly arranged on the base 2 in a circular array with the central axis as the center.

[0038] See appendix Figure 2 The pressing mechanism 3 includes a connecting plate 30. The connecting plate 30 is provided with a pressing pin assembly 31 for vertical positioning of the terminal connector 9 and at least two push rods 32. The pressing pin assembly 31 is located on the central axis of the connecting plate 30 and is located in the central through hole 21. The push rods 32 are respectively located in the vertical channel 22 and move up and down along the vertical channel 22.

[0039] See appendix Figure 4The horizontal channel 23 is provided with a slider 4 that moves back and forth along the direction of the horizontal channel 23. The slider 4 includes a linkage part 40 and a pressing part 41. The linkage part 40 is provided with a slot 400 for inserting a push rod 32. The pressing part 41 faces the channel 20, and its end is provided with a positioning surface 410 for pressing the outer wall of the terminal connector 9. The positioning surface 410 is an arc surface. The positioning surface 410 is used to press and position the outer wall of the terminal connector 9 during the dotting action to ensure that the center of the terminal connector 9 is on the central axis, thereby ensuring the quality and effect of subsequent dotting processing. The slider 4 is also provided with a slide rail 42. The slide rail 42 is provided with a slidingly connected dotting pin 43. The head of the dotting pin 43 can pass through the slide rail 42 to the channel 20 to dot the outer wall of the terminal connector 9. See Appendix Figure 10 When processing the petal-shaped terminal connector 9, since its top is composed of multiple petal pieces, traditional dotting devices can cause the petal pieces to break or deform. By using the structure of this application to first position and hold the petal piece tightly before dotting, it can ensure that the petal piece structure is subjected to uniform force and is not easy to break or deform.

[0040] See appendix Figure 3 One end of the push rod 32 is fixedly connected to the connecting plate 30. The push rod 32 is provided with a stepped guide part 33, which is disposed in the slot 400 and moves up and down to control the slider 4 and the dotting needle 43 to move towards the channel 20 or away from the channel 20. The horizontal channels 23 are all oriented towards the central axis of the base 2, and the positioning surface 410 moves along the horizontal channels 23 towards or away from the central axis.

[0041] The contact point between the slot 400 and the stepped guide 33 is the first travel point 6, and the contact point between the dotting needle 43 and the stepped guide 33 is the second travel point 7. There is a vertical travel difference between the first travel point 6 and the second travel point 7.

[0042] The stepped guide 33 includes a pushing part 330 and a resetting part 331 respectively disposed on the two sides of the push rod in a relative manner. The pushing part 330 faces the central axis of the central through hole 21. The two symmetrically arranged inner walls of the slot 400 are provided with contact parts 400a. The contact part 400a near the pressing part 41 is used to contact the pushing part 330 and control the slider 4 to push towards the channel 20. The other contact part 400a is used to contact the resetting part 331 and control the slider 4 to move away from the channel 20 and exit. The stepped guide 33 is used to control the slider 4 to perform a pushing or retracting reciprocating motion along the horizontal slide 42.

[0043] See appendix Figure 3 and appendices Figures 7-9 The pushing part 330 includes, from top to bottom, a first vertical plane 330a, a first inclined plane 330b, and a second vertical plane 330c. The bottom end of the first vertical plane 330a is connected to one end of the first inclined plane 330b, and the other end of the first inclined plane 330b is connected to the top end of the second vertical plane 330c, forming a first fitting notch 330d. The pushing part 330 is used to control the slider 4 and the pressure pin assembly 31 to be pushed out gradually towards the central axis, thereby realizing the first positioning and then marking action of the terminal connector 9, ensuring the quality and efficiency of the marking. That is, when the push rod 32 is pressed down, the second vertical plane 330c fits against the contact part 400a close to the pressing part 41. The push rod 32 continues to press down, causing the first inclined plane 330a to fit against the contact part 400a close to the pressing part 41. When the bottom end of 330b contacts the contact part 400a, triggering the first stroke point 6, it drives the slider 4 to push out along the horizontal channel 23 towards the central axis. Simultaneously, the dotting needle 43 moves backward along the slide 42 towards the second vertical plane 330c. When it moves backward to the second stroke point 7 and contacts the bottom end of the first inclined plane 330b, it triggers the dotting needle 43 to move along the slide 42 towards the central axis. When the first stroke point 6 contacts the bottom end of the first vertical plane 330a, the positioning surface 410 abuts against the outer wall of the terminal connector 9. The push rod 32 continues to press down, causing the second stroke point 7 to contact the bottom end of the first vertical plane 330a, which drives the dotting part of the dotting needle 43 to pass through the positioning surface 410 of the slider 4 and perform a dotting action on the outer wall of the terminal connector 9.

[0044] The reset portion 331 comprises, from top to bottom, a third vertical plane 331a, a second inclined plane 331b, and a fourth vertical plane 331c. The bottom end of the third vertical plane 331a is connected to one end of the second inclined plane 331b, and the other end of the second inclined plane 331b is connected to the top end of the fourth vertical plane 331c to form a second fitting recess 331d. The second inclined plane 331b creates a distance difference between the third vertical plane 331a and the fourth vertical plane 331c. The reset portion 331 is used to control the slider 4 and the dotting needle 43 to retract away from the groove after dotting processing. When the terminal connector 9 on channel 20, i.e., the push rod 32, rises, the contact portion 400a is attached to the second inclined surface 331b through the fitting notch 331d from the third vertical plane 331a. As the push rod 32 continues to rise, the contact portion 400a moves along the second inclined surface 331b toward the fourth vertical plane 331c. Simultaneously, the slider 4 retracts along the horizontal channel 32 and drives the dotting pin 43 to retract and disengage from the outer wall of the terminal connector 9. When the surface of the contact portion 400a is attached to the fourth vertical plane 331c, the slider 4 returns to its initial position, and at the same time, the dotting portion of the dotting pin 43 is exposed from the positioning surface 410.

[0045] In another embodiment, the junctions of the first vertical plane 330a and the first inclined plane 330b, the junctions of the first inclined plane 330b and the second vertical plane 330c, the junctions of the third vertical plane 331a and the second inclined plane 331b, and the junctions of the second inclined plane 331b and the fourth vertical plane 331c are all provided with arc surfaces. The arc surfaces are used to provide smooth contact with the first arc surface 400b and the second arc surface 400c, thereby ensuring the efficiency of subsequent processing operations.

[0046] See appendix Figure 5 and appendix Figure 6 The slide 42 includes a first slide 420 and a second slide 421 communicating with the first slide 420. The first slide 420 passes through the contact portion 400a, and the second slide 421 passes through the positioning surface 410 to the outside. The dotting needle 43 is disposed in the second slide 421 and can be pushed out or retracted along the direction of the second slide 421. The dotting needle 43 is provided with a sliding portion 430, and the end of the dotting needle 43 is provided with a dotting portion. The sliding portion 430 is disposed in the first slide 420, and the sliding portion 430 can be pushed out or retracted along the direction of the first slide 420. The slide 42 is used to control the dotting needle 43. When the slider 4 moves away from the channel 20, the second slide 421 drives the sliding part 430 to move backward, simultaneously driving the dotting needle 43 to move backward; when the slider 4 moves towards the channel 20, the sliding part 430 moves backward along the first slide 420, simultaneously driving the dotting needle 43 to move backward along the second slide 421. After the slider 4 moves into position, the pushing part 330 pushes the sliding part 430 to move towards the channel 20 along the first slide 420, and simultaneously the dotting needle 43 is pushed out along the second slide 421. The dotting needle 43 passes through the positioning surface 410 and abuts against the outer wall of the terminal connector 9, and then performs dotting processing.

[0047] See appendix Figure 2The pressure pin assembly 31 includes a sleeve 310, a first spring 311, and a pressure block 312. The sleeve 310 has a sliding cavity 310a. The pressure block 312 is disposed in the sliding cavity 310a and can move up and down along the direction of the sliding cavity 310a. The first spring 311 is disposed between the pressure block 312 and the top of the sleeve 310. The first spring 311 is used to provide elastic force, thereby ensuring the clamping force when the pressure block 312 drives the pressure pin 312a to press the terminal connector 9. The sliding cavity 310a has a through hole. The pressure block 312 has a pressure pin 312a. The end face of the pressure pin 312a is used to flatten the top end of the terminal connector 9 when pressing down. The pressure pin 312a extends out of the through hole to the outside. The pressure pin assembly 31 is used to ensure that the top end face of the terminal connector 9 is pressed during the dotting action, thereby ensuring the positional stability of the terminal connector 9 on the vertical axis, preventing the terminal connector 9 from shifting, and thus ensuring the subsequent dotting quality.

[0048] In another embodiment, at least two return springs 5 ​​are provided between the base 2 and the connecting plate 30. The base 2 is provided with at least two first grooves, and the connecting plate 30 is provided with at least two second grooves. The second grooves are correspondingly arranged above the first grooves. The return springs 5 ​​are arranged between the first grooves and the second grooves. The return springs 5 ​​are used to provide a return force, thereby controlling the push rod 32 to rise and drive the slider 4 to exit, thus improving the efficiency of the dotting action.

[0049] The connecting plate 30 is provided with a fixing plate 300. The fixing plate 300 is provided with multiple through holes or multiple threaded holes for connecting with external driving components. The fixing plate 300 is used to connect with the driving end of the external driving components, thereby driving the connector dotting assembly device 1.

[0050] See appendix Figure 6 The sliding part 430 is provided with a first spherical surface, which serves as a guide to provide smoothness for subsequent ejection and dotting actions, thereby improving dotting quality.

[0051] The upper edge of the contact portion 400a near the pressing portion 41 is provided with a first arc surface 400b, and the lower edge of the other contact portion 400a is provided with a second arc surface 400c. The first arc surface 400b and the second arc surface 400c are used to guide, reduce jamming during movement, and improve the smoothness of the operation of the pushing portion 330 or the resetting portion 331, thereby improving the efficiency of subsequent fixing and dotting operations of the terminal connector 9.

[0052] The base 2 is an integral base or a split base. The split base includes a base and a cover plate. The cover plate and the base are fixedly connected by one of the following: threaded connection structure, snap-fit ​​connection structure, welding connection or adhesive bonding.

[0053] This invention innovatively performs a pre-positioning and post-positioning action on a terminal connector by using a push rod with a pushing part, a slider with a positioning surface, and a marking pin. During the marking process, the pushing part controls the slider with the positioning surface to first position and fix the outer wall of the terminal connector, ensuring the center of the terminal connector is aligned with the central axis and preventing displacement. Then, after the slider is pushed into place, the pushing part pushes the marking pin out of the slider to perform the marking process on the positioned terminal connector, ensuring the quality of the marking assembly. Furthermore, when processing petal-shaped terminal connectors, this pre-positioning and clamping before marking ensures uniform stress on the petal structure, solving the problem of petal breakage or deformation caused by traditional marking devices. A reset part is included to retract and reset the slider and marking pin after marking, saving on the need for a pressure spring and reducing the impact of spring failure on subsequent marking operations, ensuring the normal operation and processing efficiency of the connector marking assembly device. By setting a channel for the terminal connector to pass through and a central through hole through the channel, the terminal connector can be moved into place and then fitted with a pressing mechanism to achieve positional stability on the vertical axis and horizontal position of the terminal connector. This allows for subsequent dotting processing, saving steps and improving the quality and efficiency of subsequent dotting.
