Description

Technical Field

[0001] This utility model relates to the field of connector manufacturing equipment technology, specifically to a pin insertion device for connectors. Background Technology

[0002] Electronic devices are typically connected using connectors to transmit current and signals. Connectors consist of terminals and a base. During connector manufacturing, the terminals are first placed in the corresponding positions on the base, and then one end of the terminal is pressed into the base for fixation. Terminals ensure the robustness of the connection between devices and reduce the risk of electrical leakage.

[0003] Traditional terminal pin insertion methods involve manually inserting pins one by one, which means inserting the pin strip into the terminal and then removing the strip. This method is prone to operational errors and is not very efficient. At the same time, there are some pin insertion machines on the market, but they usually push the pins back directly after insertion, which can easily scratch the terminal and leave scratches on its surface. This can affect the appearance or even the product performance. Summary of the Invention

[0004] The purpose of this utility model is to provide a pin insertion device for connectors, in order to solve the problems mentioned in the background art. The traditional method of pin insertion is to manually insert single pins, that is, insert the pin tape into the terminal and then remove the material tape from the pin tape. This is prone to operational errors and has low work efficiency.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] like Figure 1-8 This is a schematic diagram of a preferred embodiment of the present invention for a connector pin insertion device. In this embodiment, the connector pin insertion device includes a workbench 1, pin insertion devices 2 fixedly mounted at both ends of the workbench 1, and a transmission device 3 for conveying and connecting pins installed on the top of the workbench 1 between the two pin insertion devices 2. A transposition component 4 cooperating with the pin insertion device 2 is provided on the input side of the transmission device 3. A tray assembly 5 is fixedly mounted on the workbench 1 behind and to the side of the pin insertion device 2. The pin insertion device 2 includes a displacement component 21 and a pin insertion component 22. The displacement component 21 and the pin insertion component 22 are both mounted on the surface of the workbench 1, with the displacement component 21 located at the front end of the pin insertion component 22. The pin insertion component 22 enables the insertion of pins onto the surface of the connector housing. After the insertion is completed, the displacement component 21 moves the connector housing to the next process. In combination with the structural design of this utility model, by setting the pin insertion device 2, the transmission device 3 and the transposition component 4, the production of connectors has an automatic pin insertion function in the pin insertion process, replacing the traditional manual pin insertion method, thereby effectively reducing pin insertion errors and improving production efficiency.

[0022] In this embodiment, as Figure 4 As shown, the pin assembly 22 includes an adjustment mechanism 221, a pin insertion mechanism 222, and a feeding mechanism 223. The adjustment mechanism 221 is mounted on the surface of the workbench 1, and the pin insertion mechanism 222 is slidably mounted above the adjustment mechanism 221. The feeding mechanism 223 is mounted at the front end of the pin insertion mechanism 222. The distance between the pin insertion mechanism 222 and the displacement assembly 21 is adjusted by the adjustment mechanism 221 to ensure that the pin can be better inserted into the connector housing inside the displacement assembly 21.

[0023] In this embodiment, as Figure 7 As shown, the adjustment mechanism 221 includes an adjustment mounting base 2211, an adjustment guide rail 2212, an adjustment slider 2213, an adjustment connecting plate 2214, an adjustment handle 2216, and an adjustment hydraulic rod 2215. The adjustment mounting base 2211 is fixedly installed on the surface of the workbench 1. The top surface of the adjustment mounting base 2211 is fixedly connected to the adjustment guide rails 2212 on both sides. The adjustment connecting plate 2214 is slidably connected to the surface of the adjustment guide rails 2212 through the adjustment slider 2213. An adjustment hydraulic rod 2215 is fixedly installed on the outer wall of one of the adjustment guide rails 2212. The adjustment connecting plate 2214 is rotatably connected to the outer wall on the same side as the adjustment hydraulic rod 2215, and the bottom of the adjustment handle 2216 is connected to the adjustment hydraulic rod 2215.

[0024] In practical use, the hydraulic rod 2215 is installed in a fixed position. The operator pulls the adjustment handle 2216, causing the handle of the adjustment handle 2216 to move forward and backward. The adjustment connecting plate 2214 connected to the adjustment handle 2216 moves back and forth along with the adjustment handle 2216 through the sliding connection between the adjustment guide rail 2212 and the adjustment slider 2213.

[0025] In this embodiment, as Figure 8 As shown, the pin insertion mechanism 222 includes a pin protection housing 2221, a pin drive motor 2222, a drive wheel 2223, a driven wheel 2224, a drive disk 2225, and a pin pushing block 2226. The pin protection housing 2221 and the pin drive motor 2222 are fixedly installed on the top surface of the adjusting connecting plate 2214, with the pin drive motor 2222 located behind the pin protection housing 2221. The drive disk 2225 is rotatably connected inside the pin protection housing 2221. The drive wheel 2223 and the driven wheel 2224 are respectively installed at the bottom of the adjusting connecting plate 2214, located below the pin drive motor 2226. The drive wheel 2223 is connected to the output end of the pin drive motor 2222, and the driven wheel 2224 is connected to the bottom of the drive disk 2225. The drive wheel 2223 and the driven wheel 2224 are connected by a belt 2227. The pin push block 2226 is movably connected to the front end of the surface of the pin protection box 2221 through the pin drive rod 2228. The end of the pin drive rod 2228 away from the pin push block 2226 is movably connected to the drive disk 2225.

[0026] In practical use, the output of the pin drive motor 2222 causes the drive wheel 2223 to rotate. The driven wheel 2224, which is connected to the drive wheel 2223 by the belt 2227, rotates synchronously. The rotation of the driven wheel 2224 drives the drive disk 2225 to rotate. Since the drive disk 2225 has an elliptical structure, the pin drive rod 2228 is movably connected to the drive disk 2225. Due to the elliptical design of the drive disk 2225, the pin drive rod 2228 can move back and forth during the rotation process. The back and forth movement of the pin drive rod 2228 drives the pin push block 2226 to insert the terminal into the connector housing.

[0027] In this embodiment, as Figure 8 As shown, the feeding mechanism 223 includes a feeding support base 2231, a feeding drive motor 2232, a feeding gear 2233, a feeding hopper 2234, and a folding assembly 224. The feeding support base 2231 is fixedly installed on the front surface of the pin protection box 2221. A feeding groove 2235 is opened in the middle of the surface of the feeding support base 2231. The feeding gear 2233 is rotatably connected to one side of the surface of the feeding support base 2231 located in the feeding groove 2235. The feeding drive motor 2232 is installed inside the pin protection box 2221 at the front end of the drive disc 2225. The output end of the feeding drive motor 2232 is connected to the feeding gear 2233. The top of the feeding support base 2231... A feeding hopper 2234 is installed at the opening of the feeding trough 2235. The design of the feeding hopper 2234 can effectively prevent the material belt from splashing during the rotation and pulling of the feeding gear 2233. A folding component 224 is provided at the bottom of the feeding support 2231. The folding component 224 includes a folding drive cylinder 2241, a folding drive rod 2242, and a folding block 2243. The folding drive cylinder 2241 is installed at the rear end of the bottom of the feeding support 2231. The folding block 2243 is slidably connected to the front end of the bottom of the feeding support 2231. The folding drive rod 2242 is connected to the folding block 2243 and the folding drive cylinder 2241 by a connecting pin.

[0028] In practical use, the feeding drive motor 2232 drives the feeding gear 2233 to rotate. The evenly distributed teeth on the surface of the feeding gear 2233 mesh with the teeth on the surface of the strip, causing the strip to move in the feeding groove 2235. During the movement of the strip, the synchronously cooperating pin push block 2226 inserts the terminals on the surface of the strip into the connector housing one by one. At the same time, under the drive of the folding drive cylinder 2241, the folding drive rod 2242 swings left and right around the connecting pins at both ends, realizing the folding block 2243 to fold the strip after the pin insertion.

[0029] In this embodiment, as Figure 5As shown, the displacement assembly 21 includes a displacement mounting base 211, a displacement guide rail 212, a displacement drive motor 213, a displacement block 214, and a guide plate 215. The displacement mounting base 211 is fixedly mounted on the surface of the worktable 1. The displacement guide rail 212 is mounted on both the upper and lower ends of the inner wall of the displacement mounting base 211. The displacement drive motor 213 is fixedly mounted on one end of the displacement guide rail 212. A lead screw 216 is rotatably connected inside the displacement guide rail 212, and the lead screw 216 is connected to the output end of the displacement drive motor 213. The displacement block 214 is slidably connected to the surface of the lead screw 216, and the guide plate 215 is fixedly connected to the surface of the displacement block 214.

[0030] In practical use, the output rotation of the displacement drive motor 213 drives the lead screw 216 to rotate within the displacement guide rail 212. The displacement block 214, which is threadedly connected to the lead screw 216, moves laterally under the rotation of the lead screw 216. The guide plate 215, fixed to the displacement block 214, moves the connector housing by contacting the top of the guide plate 215 with the surface of the connector housing, thereby achieving the function of displacing the connector after the pins are inserted.

The transmission drive motor 33 is fixedly mounted on the rear end face of the transmission guide rail frame 32. The transmission drive wheel 35 is connected to the output end of the transmission drive motor 33 to realize the rotation of the transmission drive wheel 35. Multiple transmission tension wheels 36 are rotatably connected to the front end face of the transmission guide rail frame 32 to tension the conveyor belt 34 and ensure that the conveyor belt 34 can run smoothly. Under the drive of the conveyor belt 34, the transmission tension wheels 36 rotate synchronously. The conveyor belt 34 moves on the surface of the transmission guide rail frame 32, the transmission drive wheel 35, and the transmission tension wheels 36. The connector housing can move smoothly on the surface of the transmission guide rail frame 32 under the conveying of the conveyor belt 34.

[0032] In this embodiment, as Figure 4As shown, the transposition component 4 includes a transposition support 41, a transposition telescopic cylinder 43, a transposition guide rail 42, and a transposition block 44.

The transposition block 44 is slidably connected to the transposition guide rail 42, and the rear end face of the transposition block 44 is connected to the transposition telescopic cylinder 43. Through the extension and retraction output of the transposition telescopic cylinder 43, the transposition block 44 is slidably connected to the transposition guide rail 42. The transposition block 44 slidably connected to the transposition guide rail 42 thus moves between the transmission guide rail frame 32 and the displacement guide rail 212.
