Description

Technical Field

[0001] This utility model relates to the field of electrical connectors, and more specifically to a high-speed electrical connector gasket insertion device. Background Technology

[0002] PCI-e is the third-generation I / O bus after ISA and PCI buses, serving as a high-speed connection standard for peripheral devices. PCI-e electrical connectors are used for data transmission between the graphics card and the motherboard. Some PCI-e electrical connectors use a surface-mount mounting method, meaning the solder pads on the terminals are bonded to the printed circuit board. To position the PCI-e electrical connector on the printed circuit board and provide support, preventing direct stress on the solder pads, symmetrical metal pads are typically mounted at both ends of the connector's bottom.

[0003] During the assembly of electrical connectors, the metal gaskets at both ends require two workstations to install. In addition to increased equipment investment, this also increases the length of the production line, occupies a large space, and cannot be adapted to the production of different models of electrical connectors. Summary of the Invention

[0004] To enable a single workstation to install two gaskets and to accommodate gasket installation for different connector models, this invention provides a high-speed electrical connector gasket insertion device.

[0005] The technical solution adopted by this utility model is as follows: A high-speed electrical connector gasket insertion device includes an insertion unit, a flipping unit, and a shifting unit. The flipping unit corresponds to the insertion unit, and the insertion unit is mounted on the shifting unit. The shifting unit includes a pair of parallel horizontal rails and a sliding support frame mounted on the pair of horizontal rails. The insertion unit is fixed to the top of the sliding support frame, and the sliding support frame is connected to a linear drive device. The flipping unit includes a fixed bracket, on which a rotating shaft is rotatably supported via a bearing seat. One end of the rotating shaft is connected to a motor, which is fixedly mounted on one side of the bracket. The other end of the rotating shaft is mounted to a rotating bracket, on which a feed channel is fixedly mounted. The electrical connector is confined within the feed channel. After the insertion unit inserts a gasket into one end of the electrical connector, the flipping unit flips the electrical connector 180°, and the shifting unit moves the insertion unit to the other end of the electrical connector corresponding to the gasket position.

[0006] Furthermore, the insertion unit includes a frame, within which a vertical drive shaft is installed. A reduction drive structure is connected to the lower end of the drive shaft. From top to bottom, a feeding cam, a cutting cam, a clamping cam, and a pressing cam are sequentially installed on the drive shaft. A pressing seat and a pair of clamping seats are installed within the frame. The pressing seat is slidably supported on the frame by a pair of horizontal linear tracks perpendicular to the electrical connector. The pair of clamping seats are slidably supported on the top of the pressing seat by a pair of horizontal linear tracks parallel to the electrical connector. The cutting cam and the clamping cam each pull the pair of clamping seats towards each other via a connecting rod. Clamping claws are respectively provided on the front sides of the opposite faces of the pair of clamping seats, forming a shearing action between the inner sides of the clamping claws. The pressing cam pushes the pressing seat towards the electrical connector.

[0007] Furthermore, the side of the feeding cam is provided with an arc-shaped groove. The feeding cam is connected to the pawl through a feeding connecting rod. The middle part of the feeding connecting rod is hinged to the frame through a waist-shaped groove. One end of the feeding connecting rod is engaged with the arc-shaped groove of the feeding cam through a round pin, and the other end is hinged to the pawl.

[0008] Furthermore, the claw is guided and limited by a baffle mounted on the frame, and the claw is provided with a spring pin, which engages with continuous positioning holes on the pad strip.

[0009] Furthermore, the frame is provided with a vertical material guide groove, the claw is located on one side of the material guide groove, the material channel guide groove is provided on the side corresponding to the claw, and the spring needle of the claw passes through the material feeding groove to feed the material.

[0010] Furthermore, the linear drive device includes a drive motor, a lead screw, and a nut, with the nut fixedly mounted on the sliding support frame.

[0011] After adopting the above technical solution, the beneficial effects of this utility model are as follows: By setting the flipping unit, the flow channel is flipped 180 degrees, enabling the installation of two gaskets in a single workstation, thereby reducing the number of workstations, reducing equipment investment, and saving space. By setting the shifting unit, the shifting unit can drive the pressing unit to move, which can adapt to the gasket installation during the production of products of different sizes.

[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings: As shown in the figure, the high-speed electrical connector pad insertion device consists of three parts: an insertion unit, a flipping unit, and a shifting unit. It is used for installing the bottom metal pads of PCI-e series electrical connector products.

[0019] To enable the installation of two symmetrically positioned gaskets at a single workstation, this technical solution utilizes a flip unit. After inserting the first gasket, the flip unit flips the electrical connector 1, adjusting the installation position of the second gasket to the insertion unit. Since different products in the PCI-e series have varying lengths, in order to accommodate gasket installations for products of different sizes, in addition to the flip unit, a shifting unit is also used to move the insertion unit, thereby adapting to the installation of gaskets for products of different specifications and sizes, and improving the versatility of the device.

[0020] The insertion unit mainly consists of a main frame 2, a vertical drive shaft 3 installed within the main frame 2, and multiple cams mounted on the drive shaft 3. A reduction drive structure is connected to the lower end of the drive shaft 3 for power drive. From top to bottom, the drive shaft 3 is equipped with a feeding cam 4, a cutting cam 5, a clamping cam 6, and a pressing cam 7. A pressing seat 8 and a pair of clamping seats 9 are installed within the frame. The pressing seat 8 is slidably supported on the frame by a pair of horizontal linear tracks 10 perpendicular to the electrical connector. The pair of clamping seats 9 are slidably supported on the top surface of the pressing seat 8 by a pair of horizontal linear tracks 11 parallel to the electrical connector. The cutting cam 5 and the clamping cam 6 respectively pull the pair of clamping seats 9 towards each other via a connecting rod and a slider. Clamping claws 12 are respectively provided on the front sides of the opposite surfaces of the pair of clamping seats 9. A shearing action is formed between the inner sides of the clamping claws 12, which clamp and cut the gasket. The pressing cam 7 pushes the pressing seat 8 towards the electrical connector, thereby causing the clamping claws 12 to insert the gasket into the electrical connector 1. Both sides of the clamping seat 9 and the pressing seat 8 are connected to the main frame 2 by springs to achieve reset after insertion.

[0021] The main frame 2 is provided with a vertical material guide groove 13. The gasket material strip is fed downward along the guide groove 13. The feeding cam 4 is used to drive the pawl 14 to move the gasket material strip in the guide groove 13, thereby realizing feeding. The pawl 14 is guided and limited by a baffle installed on the main frame 2, restricting the pawl 14 to only move up and down. The feeding cam 4 is connected to the pawl through the feeding connecting rod 15 and the slider, converting its rotational motion into the up and down motion of the pawl 14. Specifically, the outer cylindrical side of the feeding cam 4 is provided with an arc-shaped groove. The middle part of the feeding connecting rod 15 is hinged to the frame through a waist-shaped groove. One end of the feeding connecting rod 15 is engaged with the arc-shaped groove of the feeding cam through a round pin, and the other end is hinged to the pawl 14. When the feeding cam 4 rotates, it drives the pawl 14 to swing vertically, thereby driving the pawl 14 to move vertically up and down.

[0022] The claw 14 is located on one side of the material guide groove 13. The material guide groove 13 is provided with a feeding groove on the side corresponding to the claw. The claw 14 is provided with a spring needle. The spring needle passes through the feeding groove and cooperates with the continuous positioning hole on the pad material strip. When the claw 14 feeds material, the spring needle pushes the material strip down. When the claw moves upward, the spring needle retracts due to the slope setting on the end face.

[0023] The flipping unit includes a fixed bracket 16, on which a rotating shaft 18 is rotatably supported via a bearing seat 17. One end of the rotating shaft 18 is connected to a motor 19, which is fixedly mounted on one side of the bracket. The other end of the rotating shaft 18 is mounted on a rotating bracket 20, on which a material channel 21 is fixedly mounted. The electrical connector 1 is confined within the channel 21 of the material channel. After the insertion unit inserts the gasket into one end of the electrical connector 1, the motor 19 drives the rotating bracket 20 to rotate 180°, rotating the other end of the electrical connector 1 to the insertion unit.

[0024] The shifting unit includes a pair of parallel horizontal rails 22, a sliding support frame 23 mounted on the pair of horizontal rails 22, and a linear drive device 24 for driving the sliding support frame 23. The insertion unit is fixed to the top of the sliding support frame 23. The linear drive device includes a drive motor, a lead screw, and a nut, with the nut fixedly mounted on the sliding support frame. When changing product series, the motor pushes the sliding support frame with the nut mounted on it via the lead screw, moving the insertion unit to the position corresponding to the gasket on the other end of the electrical connector.
