Description

Technical Field

[0001] This utility model relates to the field of pin insertion machines, and in particular to a pin insertion machine for connector production. Background Technology

[0002] In the connector manufacturing process, the pin insertion process is one of the core steps. Its quality directly determines the electrical performance, mechanical stability and reliability of the connector. Its main function is to accurately and firmly assemble the metal conductor into the designated hole of the insulating base to form the core path for current or signal transmission.

[0003] For example, patent document CN221487044U discloses a pin insertion machine for connector production, including a workbench; a conveyor belt is slidably connected to the top of the workbench; a pin insertion device is slidably connected to the center of the top surface of the workbench above the conveyor belt; electric push rods are fixedly connected to both side walls of the workbench; a limit block is fixedly connected to the output end of the electric push rod; a first groove is opened on the side wall of the limit block; the first groove is trapezoidal, and a rubber diaphragm is fixedly connected to its center; by using a pair of limit blocks installed at the output ends of a pair of electric push rods, a pair of rubber diaphragms can be wrapped with the outer wall of the plastic part under pressure. Under the elastic force of the rubber diaphragm itself, combined with the limiting effect of the limit blocks on the corners of the plastic part, the plastic part is fixed, increasing the adaptability of the equipment to different types of plastic parts and reducing the cumbersome operation of replacing the fixing device.

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figures 1-8As shown, a pin insertion machine for connector production includes a main body, which includes a main support 101. A transverse drive assembly is mounted on the main support 101, and a pin insertion head 107 is mounted on the transverse drive assembly. The pin insertion head 107 is prior art, and its specific structure will not be described here. A metal pin feeding device is provided on one side of the main support 101; this device is prior art and will not be described here. A positioning and bearing mechanism is provided on the main support 101, which includes a positioning frame 205 slidably connected to the main support 101. 1. A longitudinal drive assembly for moving the positioning frame 205 is installed at the lower end. An upper contour baffle 203 is fixedly connected to the positioning frame 205. Several evenly distributed conical recesses 204 are fixedly connected to the top of the positioning frame 205. A material support plate 201 is provided below the upper contour baffle 203. The material support plate 201 and the upper contour baffle 203 are provided with different grooves according to the shape of the insulating base. Several conical columns 202 are fixedly connected to the material support plate 201. The conical columns 202 and the conical recesses 204 can cooperate for positioning. 2. The lower end of the 05 is equipped with a lifting mechanism, which includes a second hydraulic cylinder 401. Two grippers 405 are installed at the output end of the second hydraulic cylinder 401. An inverted conical clamping block 406 is fixedly connected to the bottom of the material support plate 201. In use, the operator or the feeding device places several insulating bases on the material support plate 201 in advance. Then, the lifting mechanism is activated, and the second hydraulic cylinder 401 pushes the material support plate 201 upwards. During this process, the grippers 405 clamp the inverted conical clamping block 406, completing the first positioning. The material support plate 201 then rises to a certain position. After positioning, the conical column 202 and the conical concave block 204 engage to perform a second positioning. Thus, when the material carrier plate 201 and the upper contour baffle 203 clamp the insulating base, the positioning of the insulating base is ensured by positioning on both sides. Subsequently, the transverse drive assembly drives the pin insertion head 107 to move, picks up a metal pin from the metal pin feeding device on one side, and then moves it above the upper contour baffle 203. The longitudinal drive assembly drives the positioning frame 205 to move, and the positioning frame 205 cooperates with the pin insertion head 107 to perform the pin insertion operation on the insulating base.

[0030] Two conveyor belt assemblies 102 are fixedly connected to the main support 101, which are arranged symmetrically on the left and right. The material carrying plate 201 is placed on the two conveyor belt assemblies 102. An upper support 103 is fixedly connected to the top rear side of the main support 101.

In use, the material carrying plate 201 is placed on the conveyor belt assembly 102, which enables continuous feeding.

[0031] The lateral drive assembly includes a lateral lead screw 105 rotatably connected to the upper end of the upper bracket 103. The lateral lead screw 105 is a precision lead screw. A lateral motor 104 is fixedly connected to one side of the upper end of the upper bracket 103. The lateral motor 104 is a servo motor. The output end of the lateral motor 104 is fixedly connected to the lateral lead screw 105. A translation frame 106 is threadedly connected to the lateral lead screw 105. The translation frame 106 is slidably connected to the upper bracket 103. The front side of the translation frame 106 is fixedly connected to the pin insertion head 107. The lateral motor 104 drives the lateral lead screw 105 to rotate. The lateral lead screw 105 drives the translation frame 106 to move. The translation frame 106 drives the pin insertion head 107 to move laterally.

[0032] The longitudinal drive assembly includes a lower bracket 206 fixedly connected to the bottom of the main bracket 101. A longitudinal lead screw 208 is rotatably connected to the lower end of the lower bracket 206. The longitudinal lead screw 208 is a precision lead screw. A longitudinal motor 207 is fixedly connected to the lower bracket 206. The longitudinal motor 207 is a servo motor. The output end of the longitudinal motor 207 is fixedly connected to the longitudinal lead screw 208. The longitudinal lead screw 208 is threadedly connected to the positioning frame 205. In use, the longitudinal motor 207 drives the longitudinal lead screw 208 to rotate, and the longitudinal lead screw 208 drives the positioning frame 205 to translate.

[0033] The lifting mechanism also includes a second guide plate 404 slidably connected to both sides of the output end of the second hydraulic cylinder 401. The second guide plate 404 is provided with a Z-shaped guide groove. The top of the second guide plate 404 is fixedly connected to the gripper 405. A fixed frame 403 is fixedly connected to the positioning frame 205. A fixed rod is provided inside the fixed frame 403. The fixed rod inside the fixed frame 403 is slidably connected to the guide groove on the second guide plate 404. In use, when the second hydraulic cylinder 401 extends, the second hydraulic cylinder 401 drives the second guide plate 404 to rise. During this process, due to the combined action of the guide groove on the second guide plate 404 and the fixed rod on the fixed frame 403, the two grippers 405 move towards the middle and clamp the inverted cone clamping block 406, thereby achieving the first positioning of the material carrying plate 201.

[0034] A linkage mechanism is provided at the rear of the main support 101. The linkage mechanism includes a first guide plate 301 slidably connected to the rear of the top of the upper support 103. The first guide plate 301 is provided with a Z-shaped guide groove. A protrusion 302 is fixedly connected to the rear of the translation frame 106. The protrusion 302 is slidably connected to the guide groove on the first guide plate 301. A first hydraulic cylinder 303 is fixedly connected to the rear of the main support 101. The output end of the first hydraulic cylinder 303 is fixedly connected to the first guide plate 301. A connecting pipe 402 is fixedly connected to one side of the lower end of the second hydraulic cylinder 401. The connecting pipe 402 and the lower end of the first hydraulic cylinder 303 are connected by a hydraulic hose 3. 04 Connection. In use, when the translation frame 106 moves the needle insertion head 107 to one side to perform the metal needle picking action, the translation frame 106 also moves the protrusion 302. The protrusion 302 cooperates with the guide groove on the first guide plate 301 to drive the first guide plate 301 to rise. The first guide plate 301 drives the internal space of the first hydraulic cylinder 303 to increase. Then, the hydraulic oil in the second hydraulic cylinder 401 flows into the first hydraulic cylinder 303 through the hydraulic hose 304. After the picking is completed, the translation frame 106 moves to the middle. At this time, the first guide plate 301 is reset and drives the second hydraulic cylinder 401 to extend.

[0035] Working Principle: Workers or a feeding device pre-place several insulating bases on the material support plate 201. The material support plate 201 is then placed on the conveyor belt assembly 102 manually or by a robotic arm. The conveyor belt assembly 102 drives the material support plate 201 to move directly below the upper contour baffle 203. Subsequently, the lifting mechanism is activated, and when the second hydraulic cylinder 401 extends, it drives the second guide plate 404 to rise. During this process, due to the combined action of the guide groove on the second guide plate 404 and the fixing rod on the fixing frame 403, the two grippers 405 move towards the center, clamping the inverted conical clamping block 406, achieving the first positioning of the material support plate 201. After the material support plate 201 rises to a certain position, the conical column 202 and the conical concave block 204 engage for the second positioning. Thus, when the material support plate 201 and the upper contour baffle 203 clamp the insulating bases, the precise position of the insulating bases is ensured through positioning on both sides. Then, the lateral driving... The moving component drives the needle insertion head 107 to move, picking up metal needles from the metal needle feeding device on one side, and then moving them above the upper contour baffle 203. The longitudinal driving component drives the positioning frame 205 to move. The positioning frame 205 works with the needle insertion head 107 to perform needle insertion on the insulating base. During the movement of the translation frame 106, the extension and retraction of the second hydraulic cylinder 401 is achieved through the linkage mechanism. The linkage principle is as follows: when the translation frame 106 drives the needle insertion head 107 to move to one side to pick up the metal needles, the translation frame 106 also drives the protrusion 302 to move. The protrusion 302 cooperates with the guide groove on the first guide plate 301, driving the first guide plate 301 to rise. The first guide plate 301 drives the internal space of the first hydraulic cylinder 303 to increase, so the hydraulic oil in the second hydraulic cylinder 401 flows into the first hydraulic cylinder 303 through the hydraulic hose 304. After the picking is completed, the translation frame 106 moves to the middle. At this time, the first guide plate 301 resets, driving the second hydraulic cylinder 401 to extend.
