In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0016] Example 1:

[0017] This embodiment provides a cam insert mechanism, which also includes: Workbench 1, on which a production line for transporting connector housings is installed; Feeding component 2 is installed on workbench 1 and is used to feed pins to the production line. The insertion component includes a fixing frame 3, a pushing assembly 4, and a clamping assembly 5. The fixing frame 3 is mounted on the worktable 1. The pushing assembly 4 is movably mounted on the fixing frame 3 in the Y direction to push the pin onto the connector housing. The clamping assembly 5 is mounted on the pushing assembly 4 to clamp and fix the pin in the X direction. The first transmission component 6 includes a rotary cam 61 and a first rocker arm 62. The two ends of the first rocker arm 62 are rotatably connected to the fixed frame 3 and the pusher assembly 4, respectively. The rotary cam 61 is rotatably installed in the fixed frame 3 and abuts against the rocker arm to drive the rocker arm to move. Two sets of second transmission components 7, each second transmission component 7 includes a control wheel 71 and a second swing arm 72. The control wheel 71 is rotatably mounted in the fixed frame 3 and a guide groove is provided on the periphery of the control wheel 71. The second swing arm 72 is rotatably mounted on the fixed frame 3 and one end of the second swing arm 72 is provided in the guide groove, and the other end is connected to the clamping assembly 5. The drive component 8 is mounted on the fixed frame 3 and is used to drive the rotary cam 61 and control the rotation of the rotary wheel 71.

[0018] In this technical solution, when the connector housing on the production line is transported to the designated position, the feeding component 2 also transports the pin to the designated position. Then, the driving component 8 drives the rotary cam 61 and the control wheel 71 to rotate synchronously. The rotation of the control wheel 71 drives the second rocker arm 72 to move, which in turn drives the clamping component 5 to clamp and fix the pin along the X direction. The rotation of the rotary cam 61 drives the first rocker arm 62 to move, which in turn drives the pushing component 4 to move along the Y direction to insert the clamped and fixed pin into the connector housing on the production line, thus completing the pin insertion operation.

[0019] Furthermore, the drive component 8 includes: a rotating shaft 81, which is rotatably fixed in the bracket 3; a drive motor 82, which is mounted on the bracket 3; and a pulley 83, which drives the drive motor 82 and the rotating shaft 81 through a transmission connection; wherein the rotating cam 61 and the control wheel 71 are both mounted on the rotating shaft 81.

[0020] An extension is provided around the circumference of the rotary cam 61, and an annular groove is formed between the rotary cam 61 and the extension. A support seat is provided inside the fixed frame 3. The first rocker arm 62 is L-shaped, with one end of the first rocker arm 62 hinged to the support seat. Connectors are provided at the other end and the middle of the first rocker arm 62. The connector at the middle of the first rocker arm 62 is located in the annular groove, and the connector at the end of the first rocker arm 62 is rotatably connected to the tail of the pusher assembly 4. When the rotary cam 61 rotates, the end of the connector moves eccentrically relative to the rotary cam 61 in the annular groove, thereby causing the first rocker arm 62 to swing. The end of the first rocker arm 62 pushes the pusher assembly 4 to move along the X direction, thereby enabling the plug to be inserted into the connector housing.

[0021] A guide groove is provided around the control wheel 71. The middle part of the second swing rod 72 is hinged to the fixed frame 3. Connectors are provided at both ends of the second swing rod 72. One end of the second swing rod 72 is rotatably connected to the clamping assembly 5 through the connector and can move relative to it in the Y direction. The connector at the other end is located in the guide groove. When the control wheel 71 rotates, the end of the second swing rod 72 slides in the guide groove. The guide groove drives the end of the second swing rod 72 to swing back and forth in the X direction, thereby driving the other end of the second swing rod 72 to swing back and forth in the X direction, so that the clamping assembly 5 can clamp or release the pin in the X direction.

[0022] In summary, by using the driving component 8 to drive the rotating cam 61 and the control wheel 71 to rotate simultaneously, and using the control wheel 71 to drive the second rocker arm 72 to swing back and forth, the clamping assembly 5 is driven to periodically open and clamp the pins; by using the rotating cam 61 to drive the first rocker arm 62 to swing back and forth, the pushing assembly 4 is driven to move periodically, and the clamping assembly 5 is driven to insert the pins back and forth into the connector housing, thereby achieving efficient assembly between the pins and the connector housing, reducing production time, improving production efficiency, and effectively increasing economic benefits.

[0023] Example 2:

[0024] This embodiment provides a cam insert mechanism, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0025] Furthermore, the pusher assembly 4 includes: Movable base 41, which is movable along the Y direction and mounted on the fixed frame 3; The pusher plate 42 is mounted on the movable base 41, and the pusher plate 42 has a positioning groove adapted to the pin structure on the end of the pusher plate 42 that is close to the production line along the Y direction.

[0026] Furthermore, the clamping assembly 5 includes two clamping members, each comprising: Clamping block 51 is movably mounted on one end of the movable base 41 near the production line along the X direction; Connecting block 52 is installed on the end of clamping block 51 that is away from feeding component 2 along the X direction; The connecting block 52 is connected to the second swing arm 72.

[0027] In this technical solution, the movable seat 41 is movably mounted on the fixed frame 3 along the Y direction via a slider guide rail assembly. The pusher plate 42 passes through the movable seat 41 along the Y direction and is located between the two clamping blocks 51. A positioning groove is provided at the head of the pusher plate 42. There can be two first rocker arms 62, which are respectively connected to the two sides of the rotary cam 61 along the X direction. One first rocker arm 62 is connected to the pusher plate 42, and the other first rocker arm 62 is connected to the movable seat 41.

[0028] The rotating cam 61 drives the two first rocker arms 62 to swing synchronously, which in turn moves the moving seat 41 and the pusher plate 42 to move synchronously closer to the needle on the feeding component 2. At the same time, the control wheel 71 also drives the two second rocker arms 72 to swing synchronously. The ends of the two second rocker arms 72 respectively push the two clamping blocks 51 to move closer to each other along the X direction on the moving seat 41 to clamp and fix the needle.

[0029] Since the pins on the feeding component 2 are conveyed in a strip and several pins are connected together, when the two clamping blocks 51 clamp and fix a pin, the pin will be exactly in the positioning groove. Then, as the pusher plate 42 moves continuously, the positioning groove and the pin come into contact, cutting the pin off from the material strip, and then the movement continues to insert the cut pin into the connector housing.

[0030] Example 3:

[0031] This embodiment provides a cam insert mechanism, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0032] Furthermore, the feeding component 2 includes The material conveying frame 21 is mounted on the fixed frame 3 and has a material conveying trough inside; The material transfer assembly is mounted on the material feeder 21 and is used to drive the pin to move along the material feeder.

[0033] A material control assembly is movably mounted on the feeder 21 in the X direction to restrict the movement of the pins within the feed trough.

[0034] Furthermore, the material transfer component includes: Material conveying motor 22 is mounted on material conveying frame 21; The material conveying toothed disc 23 is mounted on the output end of the material conveying motor 22. The material conveyor 21 is provided with a connecting groove 24 that communicates with the material conveying trough, and the material conveying toothed disc 23 engages with the pins on the material conveying trough through the connecting groove 24.

[0035] Furthermore, the feed assembly includes: Movable block 25 is mounted on conveyor frame 21 in an X-direction movably and is connected to second swing arm 72; Positioning rod 26 is mounted on movable block 25; The material conveyor 21 is provided with a positioning hole that communicates with the material conveying trough, and the positioning rod 26 is inserted into the positioning hole.

[0036] In this technical solution, the external material unwinding mechanism unwinds the pin material strip into the feeding trough. The pin material strip moves along the feeding trough, while the feeding motor 22 drives the feeding toothed disc 23 to rotate. The feeding toothed disc 23 meshes with the pin material strip, and the rotation of the feeding toothed disc 23 provides traction and transmission for the pin material strip, allowing it to be discharged from the feeding frame 21 and then clamped and fixed by the clamping assembly 5. At the same time, it is inserted into the connector housing through the pushing assembly 4, thereby completing the assembly between the pin and the connector housing.

[0037] When the outermost pin of the pin-carrying material is conveyed out of the feeder 21, the second swing rod 72 pushes the connecting block 52 to drive the clamping block 51 to clamp the pin. Simultaneously, the second swing rod 72 also pushes the moving block 25 to move along the X direction, causing the positioning rod 26 to pass through the positioning hole of the feeder 21 and insert into the feed trough to limit the movement of the pin. The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art, under the guidance of this application, can make many other forms without departing from the spirit and scope of the claims, all of which fall within the protection scope of this application.
