Description

Technical Field

[0001] This utility model relates to the field of automatic terminal insertion equipment technology, and in particular to a novel terminal insertion mechanism. Background Technology

[0002] The Chinese utility model patent with patent number ZL202123399112.3 and patent name, entitled "An Automatic Terminal Insertion Machine with Pull-out Detection Function," specifically discloses the following technical solution: An automatic terminal insertion machine with pull-out detection function includes a terminal insertion assembly fixed base plate and a component mounting frame. The lower end of the terminal insertion assembly fixed base plate is provided with a terminal insertion assembly moving slide rail and a terminal pull-out detection cylinder. The terminal pull-out detection cylinder is used for moving the entire device and for detecting the terminal insertion device after the terminal insertion device has completed the terminal insertion. The component mounting frame is provided with a terminal insertion assembly lifting cylinder, a terminal positioning clamp lifting cylinder, and a terminal wire insertion clamp. The lower end of the terminal positioning clamp lifting cylinder is provided with a terminal positioning claw, and the upper end of the terminal wire insertion clamp is provided with a drive cylinder.

[0003] When using the terminal insertion device with pull-out detection function in the above-mentioned automatic insertion machine, when it is necessary to use the terminal insertion device to perform terminal insertion operation, firstly, the terminal positioning clamp is raised to the upper stop point by the terminal positioning clamp lifting cylinder, and the terminal wire insertion clamp is opened by the drive cylinder. Then, by operating the insertion assembly moving slide rail, the terminal positioning clamp moves to the wire clamping position and clamps the wire with the terminal wire insertion clamp. At the same time, the terminal positioning clamp descends to the terminal positioning position and clamps the terminal. Next, the insertion assembly moving slide rail moves the assembly to the insertion position, so that the terminal wire insertion clamp pre-inserts the terminal into the plastic shell and then opens the terminal positioning clamp. Then, the terminal positioning clamp lifting cylinder pulls the terminal positioning clamp to the upper stop point, and the terminal wire insertion clamp pushes the wire forward to insert the terminal to the specified depth. After insertion, the terminal wire insertion clamp is opened, and the insertion assembly lifting cylinder raises the insertion clamp to the upper stop point, thus completing one insertion operation.

[0004] The terminal insertion device with pull-out detection function of the above-mentioned automatic insertion machine has the following defects: the terminal pull-out detection cylinder alone cannot accurately realize the pull-out detection after the terminal is inserted, that is, it cannot accurately determine the insertion state of the terminal. Utility Model Content

[0005] The purpose of this utility model is to provide a novel terminal insertion shell mechanism to address the shortcomings of existing technologies. This novel terminal insertion shell mechanism has a novel structural design, accurate pull-out detection, and good reliability, that is, it can accurately determine the insertion state of the terminal.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0007] A novel terminal housing mechanism includes a lifting frame, on which a terminal wire clamping assembly is mounted. The terminal wire clamping assembly includes a terminal positioning clamp, a wire clamp, and a lifting drive cylinder. The lifting drive cylinder and the wire clamp are respectively mounted on the lifting frame, and the lifting drive cylinder is drivenly connected to the terminal positioning clamp. The new terminal housing mechanism also includes a horizontally moving horizontal drive linear module, a vertically moving lifting drive linear module, and a horizontal movable frame for mounting the lifting drive linear module, with the lifting movable frame installed at the drive end of the lifting drive linear module. The drive end of the horizontal drive linear module is equipped with a download plate, and the horizontal movable seat is equipped with an upper loading plate located above the download plate. The upper surface of the download plate is screwed with a fixed guide rail, and the lower surface of the upper loading plate is screwed with a fixed slider that cooperates with the guide rail. A magnetic scale assembly is installed between the upper loading plate and the download plate. The horizontal movable frame is equipped with a clamping cylinder for pushing the guide rail and a low-friction cylinder located next to the clamping cylinder. The clamping cylinder and the low-friction cylinder move horizontally. The low-friction cylinder is equipped with a precision pressure regulating valve for adjusting the thrust. A limiting mechanism is installed between the upload board and the download board.

[0008] The magnetic scale assembly includes a magnetic scale reading head that is securely mounted on the upper plate and a magnetic scale that is securely mounted on the lower plate. The magnetic scale is parallel to the guide rail and the magnetic scale and the magnetic scale reading head are aligned.

[0009] The limiting mechanism includes a limiting block that is screwed and fastened to the upper surface of the guide rail; The upper plate is screwed to the end of the limiting block side with a limiting plate, and the limiting plate has a bolt mounting hole that extends laterally. The limit block is screwed with a limit bolt, which passes through the bolt mounting hole of the limit plate, and the limit plate is located between the limit block and the large end of the limit bolt.

[0010] The lifting drive cylinder is equipped with a lifting seat at its drive end. The lifting seat is equipped with a horizontal drive cylinder that moves horizontally and is used to drive the terminal positioning clamp away from or near the wire clamp. The horizontal drive cylinder is equipped with a horizontal seat at its drive end. The horizontal seat is equipped with a positioning drive cylinder for driving the terminal positioning clamp to move up and down. The terminal positioning clamp is provided with a left terminal clamp arm and a right terminal clamp arm arranged opposite each other. The lower ends of the left terminal clamp arm and the right terminal clamp arm are respectively provided with terminal limit hooks. The horizontal seat is also equipped with a vertically arranged vertical limiting clamp, which is located between the left terminal clamp arm and the right terminal clamp arm of the terminal positioning clamp.

[0011] Compared with existing technologies, this utility model has the following advantages: Specifically, after the shell insertion is completed, a pull-back detection is performed. The clamping cylinder retracts and moves away, while the low-friction cylinder actuates and clamps the guide rail. At this time, the force between the upper plate and the lower plate is equal to the output force of the low-friction cylinder. The force can be adjusted by a precision pressure regulating valve to ensure that the output force of the low-friction cylinder equals the pull-back force. The horizontal drive linear module drives the lower plate forward to pull back. If the terminal is not fully inserted, the lower plate and the upper plate remain relatively stationary. If the terminal is fully inserted into the shell, the upper plate and the lower plate will move relative to each other. The magnetic scale assembly records the relative displacement produced by the relative movement of the upper plate and the lower plate. By comparing the displacement of the lower plate driven by the horizontal drive linear module with the aforementioned relative displacement, the insertion state of the terminal can be determined. Therefore, this novel terminal shell insertion mechanism has the advantages of novel structural design, accurate pull-back detection, and high reliability, meaning it can accurately determine the insertion state of the terminal.

Detailed Implementation

[0017] The present invention will now be described in conjunction with specific embodiments.

[0018] Example 1, as Figure 1 and Figure 2As shown, a novel terminal housing mechanism includes a lifting frame 1, and a terminal wire clamping assembly 2 is mounted on the lifting frame 1. The terminal wire clamping assembly 2 includes a terminal positioning clamp 21, a wire clamp 22, and a lifting drive cylinder 23. The lifting drive cylinder 23 and the wire clamp 22 are respectively mounted on the lifting frame 1, and the lifting drive cylinder 23 is drivenly connected to the terminal positioning clamp 21.

[0019] Among them, such as Figure 1 and Figure 2 As shown, the new terminal housing mechanism also includes a horizontally moving horizontal drive linear module 3, a vertically moving lifting drive linear module 4, and a horizontal movable frame 5 for mounting the lifting drive linear module 4. The lifting movable frame 1 is installed at the drive end of the lifting drive linear module 4.

[0020] Furthermore, such as Figures 1 to 3 As shown, the drive end of the horizontal drive linear module 3 is provided with a download plate 31, and the horizontal movable seat is provided with an upper loading plate 51 located above the download plate 31. The upper surface of the download plate 31 is screwed with a fixed guide rail 61, and the lower surface of the upper loading plate 51 is screwed with a fixed slider 62 that cooperates with the guide rail 61. A magnetic grid ruler assembly 7 is installed between the upper loading plate 51 and the download plate 31.

[0021] Furthermore, such as Figures 1 to 3 As shown, the horizontal movable frame 5 is equipped with a clamping cylinder 81 for pushing the guide rail 61 and a low-friction cylinder 82 located next to the clamping cylinder 81. The clamping cylinder 81 and the low-friction cylinder 82 move horizontally. The low-friction cylinder 82 is equipped with a precision pressure regulating valve (not shown in the figure) for adjusting the thrust. It should be noted that the precision pressure regulating valve is installed on the air supply pipe at the air inlet end of the low-friction cylinder 82.

[0022] Furthermore, a limiting mechanism is installed between the upload board 51 and the download board 31.

[0023] Specifically, such as Figure 2 and Figure 3 As shown, the magnetic scale assembly 7 includes a magnetic scale reading head 71 that is securely mounted on the upper plate 51 and a magnetic scale 72 that is securely mounted on the lower plate 31. The magnetic scale 72 is parallel to the guide rail 61 and is aligned with the magnetic scale reading head 71.

[0024] It should be noted that the novel terminal insertion mechanism in this embodiment is applied to an automatic insertion device, which is equipped with a PLC controller. During operation, the PLC controller controls the terminal positioning clamp 21, the lifting drive cylinder 23, the wire clamp 22, the horizontal drive linear module 3, the lifting drive linear module 4, the clamping cylinder 81, and the low-friction cylinder 82 to operate, and the magnetic scale reading head 71 is electrically connected to the controller.

[0025] In the novel terminal insertion mechanism of this embodiment, when performing the insertion operation, the clamping cylinder 81 pushes the guide rail 61 to move the lower push plate relative to the upper push plate. When the lower push plate moves to the limit position relative to the upper push plate, the limiting mechanism limits it. At this time, the limiting mechanism cooperates with the clamping cylinder 81 to make the upper plate 51 and the lower plate 31 rigidly connected. The horizontal drive linear module 3 is used to control the depth of terminal insertion, and the lifting drive linear module 4 is used to control the longitudinal coordinate of terminal insertion. When performing the insertion operation, the terminal positioning clamp 21 clamps the terminal, and the wire clamp 22 clamps the wire. When inserting the terminal, the terminal part is pre-inserted into the shell. Then the terminal positioning clamp 21 is released and the lifting drive cylinder 23 lifts the terminal positioning clamp 21 to a certain height. Then the wire clamp 22 protrudes to facilitate the secondary insertion of the terminal into place.

[0026] It should be emphasized that after the new terminal insertion mechanism in this embodiment completes the insertion, a pull-back test is performed. At this time, the clamping cylinder 81 retracts and moves away from the guide rail 61, while the wire clamp 22 holds the wire. The low-friction cylinder 82, located next to the clamping cylinder 81, actuates and clamps the guide rail 61. At this time, the force between the upper plate 51 and the lower plate 31 is equal to the output force of the low-friction cylinder 82. The magnitude of the force can be adjusted by the precision pressure regulating valve so that the output force of the low-friction cylinder 82 is equal to the pull-back force. The horizontal drive linear module 3 drives the lower plate 31 to move forward and pull back. If the terminal is not inserted in place, the lower plate 31 and the upper plate 51 remain relatively stationary. If the terminal is inserted into the housing in place, the upper plate 31 moves forward and pulls back. The carrier plate 51 and the download plate 31 will move relative to each other. The magnetic scale assembly 7 records the relative displacement produced by the relative movement of the carrier plate 51 and the download plate 31. By comparing the displacement of the download plate 31 driven by the horizontal drive linear module 3 with the above relative displacement, the insertion state of the terminal can be determined. Specifically, the displacement of the download plate 31 driven by the horizontal drive linear module 3 is the pull-out stroke A, and the relative displacement produced by the relative movement of the carrier plate 51 and the download plate 31 is the relative displacement B. When A=B, it means that the terminal is fully inserted; when A is greater than B, the terminal is partially inserted. Finally, the terminal insertion action is repeated according to the terminal insertion state to ensure that the terminal is fully inserted and to ensure the quality of the housing.

[0027] In summary, the novel terminal insertion mechanism of this embodiment has the advantages of novel structural design, accurate pull-out detection, and high reliability, which means it can accurately determine the insertion state of the terminal.

[0028] Example 2, as Figure 1 and Figure 2 As shown, the difference between this embodiment 2 and embodiment 1 is that the limiting mechanism includes a limiting block 91 that is screwed and fastened to the upper surface of the guide rail 61.

[0029] Among them, the upper plate 51 is screwed to the end of the limiting block 91 side with a limiting plate 92, and the limiting plate 92 has a bolt mounting hole 921 that runs horizontally through it.

[0030] In addition, the limit block 91 is screwed with a limit bolt 93, which passes through the bolt mounting hole 921 of the limit plate 92, and the limit plate 92 is located between the limit block 91 and the large end of the limit bolt 93.

[0031] When the tightening cylinder 81 or the low-friction cylinder 82 pushes the guide rail 61, the large end of the limiting bolt 93 abuts against the limiting plate 92.

[0032] Example 3, as Figure 1 and Figure 2 As shown, the difference between this embodiment 3 and embodiment 1 is that: the driving end of the lifting drive cylinder 23 is equipped with a lifting seat 24, the lifting seat 24 is equipped with a horizontal drive cylinder 25 that moves horizontally and is used to drive the terminal positioning clamp 21 away from or close to the wire clamp 22, and the driving end of the horizontal drive cylinder 25 is equipped with a horizontal seat. The horizontal seat is equipped with a positioning drive cylinder 26 for driving the terminal positioning clamp 21 to move up and down. The terminal positioning clamp 21 is provided with a left terminal clamp arm 211 and a right terminal clamp arm 212 arranged opposite to each other. The lower ends of the left terminal clamp arm 211 and the right terminal clamp arm 212 are respectively provided with terminal limiting hooks 213. The horizontal seat is also equipped with a vertically arranged vertical limiting clamp 27, which is located between the left terminal clamp arm 211 and the right terminal clamp arm 212 of the terminal positioning clamp 21.

[0033] After the terminal is clamped by the left terminal clamping arm 211 and the right terminal clamping arm 212 of the terminal positioning clamp 21, the positioning drive cylinder 26 drives the terminal positioning clamp 21 to move upward, so that the terminal abuts against the lower edge of the vertical limiting clamp 27. At this time, the left and right sides of the terminal are positioned by the left terminal clamping arm 211 and the right terminal clamping arm 212, and the upper and lower sides of the terminal are positioned by the lower edge of the vertical limiting clamp 27 and the terminal limiting hook 213. That is, the terminal is positioned on all four sides by the rectangular clamp, and because the terminal pressing position or pressing position is square, this embodiment four can achieve accurate positioning of various terminals.

For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
