Description

Technical Field

[0001] The present invention relates to a terminal rotating device and a terminal insertion system including the terminal rotating device. Background Technology

[0002] In existing technologies, terminal patching systems typically include a conveyor for transporting terminal strips, a cutting device for cutting terminals from the terminal strip, and a gripping device for gripping the cut terminals. When the terminals on the conveyed terminal strip are straight terminals, the terminal prongs are initially in a vertical position. Therefore, the gripping device can vertically insert the terminal prongs into the sockets on the circuit board after gripping the terminal. However, when the terminals on the conveyed terminal strip are L-shaped right-angle terminals, the terminal prongs are initially in a horizontal position. Therefore, the gripping device cannot vertically insert the terminal prongs into the sockets on the circuit board after gripping the terminal. Thus, existing terminal patching systems cannot be used to patch L-shaped right-angle terminals, limiting their application range. Summary of the Invention

[0003] The purpose of this invention is to solve at least one aspect of the aforementioned problems and defects existing in the prior art.

[0004] According to one aspect of the present invention, a terminal rotating device is provided. The terminal rotating device includes: a rotating disk having four engagement slots evenly spaced along its circumference; and a drive shaft connected to the rotating disk for driving the rotating disk to rotate about its central axis. The engagement slots of the rotating disk are adapted to engage with a carrier portion on a terminal, and the rotating disk is used to rotate the terminal engaged therewith from a first position to a second position perpendicular to the first position, thereby rotating the pins of the terminal from a horizontal position to a vertical position.

[0005] According to an exemplary embodiment of the present invention, the engagement groove has an elastic cantilever located on one side thereof, the elastic cantilever being used to clamp and fix the carrier portion of the terminal inserted into the engagement groove in the engagement groove.

[0006] According to another exemplary embodiment of the present invention, an arcuate protrusion is formed at the end of the elastic cantilever, the arcuate protrusion being used to guide the carrier portion of the terminal into the engagement groove and to abut against the inserted carrier portion.

[0010] According to an exemplary embodiment of the present invention, the conveying device includes: a conveying gear whose teeth mesh with a positioning groove on the terminal strip; and a drive motor connected to the conveying gear for driving the conveying gear to rotate, wherein the terminal strip is adapted to move along a predetermined conveying direction under the drive of the conveying gear, and the tooth pitch between two adjacent teeth on the conveying gear is equal to the distance between two adjacent terminals on the terminal strip.

[0011] According to another exemplary embodiment of the present invention, the conveying device further includes: a conveying channel extending along the predetermined conveying direction for guiding the terminal strip to move along the predetermined conveying direction, wherein the terminal strip is movably positioned in the conveying channel such that the terminals on the conveyed terminal strip are in the first posture.

[0012] According to another exemplary embodiment of the present invention, the cutting device includes: a cutting tool located on one side of the rotating disk and having a first cutting portion and a second cutting portion, the cutting tool being movable relative to the rotating disk between an initial position and a cutting position. When the cutting tool is moved to the cutting position, the first cutting portion cuts off the first terminal at the front end of the terminal strip from the terminal strip, while the second cutting portion cuts off the carrier tape portion on the terminal that has been rotated to the second orientation by the rotating disk.

[0013] According to another exemplary embodiment of the present invention, before the cutting tool is moved to the cutting position, the gripping device grips the terminal that has been rotated to the second posture by the rotary disk, so as to ensure that the terminal remains stationary when the carrier tape portion on the terminal is cut off.

[0016] According to another exemplary embodiment of the present invention, the terminal insertion system further includes: an elastic pushing device located on the opposite side of the rotating disk, opposite to the cutting tool. The elastic pushing device abuts against the second terminal at the front end of the terminal strip to ensure that after the first terminal at the front end of the terminal strip is cut off from the terminal strip by the first cutting part, the front end of the terminal strip can automatically reset under the pushing of the elastic pushing device.

[0017] According to another exemplary embodiment of the present invention, the elastic pushing device includes: a push block abutting against a second terminal at the front end of the terminal strip; and a return spring applying an elastic return force to the push block.

[0023] According to another exemplary embodiment of the present invention, the position holding device includes: a brake block adapted to frictionally engage with the drive shaft; and a brake spring for applying a braking force to the brake block. When the position holding device is moved to the holding position, the brake block abuts against the drive shaft to prevent rotation of the drive shaft and the rotating disk.

[0024] According to another exemplary embodiment of the present invention, the gripping device includes: a gripper adapted to hold and grasp a terminal that has been rotated to the second posture by the rotating disk; and a moving mechanism for moving the gripper and the terminal grasped by the gripper.

[0025] According to another exemplary embodiment of the present invention, the moving mechanism is a three-axis translation mechanism or a multi-degree-of-freedom robot.

[0026] According to another exemplary embodiment of the present invention, the terminal includes: a plate-shaped body; a mating pin connected to the plate-shaped body for mating with a mating terminal; and a plug pin connected to the plate-shaped body for insertion into a socket on a circuit board. The extending direction of the mating pin is perpendicular to the extending direction of the plug pin, such that the terminal is L-shaped. The gripping device grips the terminal by clamping the plate-shaped body of the terminal, and the carrier tape portion is connected to the plate-shaped body of the terminal.

[0027] In the aforementioned exemplary embodiments of the present invention, the terminal rotating device can rotate the plug pin of the L-shaped right-angle terminal from the horizontal position to the vertical position, so that the terminal plugging system can be used not only for plugging straight terminals, but also for plugging L-shaped right-angle terminals, thus expanding the application range of the terminal plugging system.

The terminal strip 8 is adapted to move along a predetermined conveying direction under the drive of the conveying gear 20, and the tooth pitch between two adjacent teeth 20a on the conveying gear 20 is equal to the distance (or pitch) between two adjacent terminals 80 on the terminal strip 8.

[0056] like Figures 1 to 15As shown, in the illustrated embodiment, the conveying device 2 further includes a conveying channel (not shown) extending along a predetermined conveying direction for guiding the terminal strip 8 to move along the predetermined conveying direction. The terminal strip 8 is movably positioned in the conveying channel such that the terminals 80 on the conveyed terminal strip 8 are in a first posture.

[0057] like Figures 1 to 15 As shown in the illustrated embodiment, the cutting device 3 includes a cutting tool 30 located on one side of the rotating disk 10 and having a first cutting portion 31 and a second cutting portion 32. The cutting tool 30 is movable relative to the rotating disk 10 between an initial position and a cutting position.

[0065] like Figures 1 to 15 As shown, in the illustrated embodiment, the second cutting portion 32 of the cutting tool 30 is used to cut off the carrier tape portion 84 on the terminal 80 and to push the cut-off carrier tape portion 84 into the vacuum suction port 61 of the vacuum suction unit 60.

[0066] like Figures 1 to 15 As shown in the illustrated embodiment, the vacuum adsorber 60 is mounted to the fixed base, and the return spring 51 is compressed between the vacuum adsorber 60 and the push block 50.

[0067] like Figures 1 to 15 As shown in the illustrated embodiment, the terminal plugging system further includes a position holding device 7 adapted to move between a release position and a holding position. When rotation of the aforementioned rotating disk 10 is not required, the position holding device 7 is moved to the holding position to hold the rotating disk 10 at a predetermined angular position.

[0070] like Figures 1 to 15 As shown in the illustrated embodiment, the aforementioned moving mechanism can be a three-axis translation mechanism or a multi-degree-of-freedom robot.

[0071] like Figures 1 to 15 As shown in the illustrated embodiment, terminal 80 includes a plate-shaped body 83, a mating pin 81, and a plug pin 82.

The gripping device 4 grips terminal 80 by clamping the plate-shaped body 83 of terminal 80, and the carrier tape portion 84 is connected to the plate-shaped body 83 of terminal 80.

[0072] The operation of the terminal plug-in system illustrated below will be explained with reference to the attached drawings.

[0073] First, such as Figure 2 and Figure 12 As shown, the gripping device 4 grips the terminal 80, which has been rotated to the second position by the rotating disk 10;

[0074] Then, as Figure 2 and Figure 12 As shown, the cutting tool 30 cuts the first terminal 80 at the front end of the terminal strip 8 off the terminal strip 8, and at the same time cuts off the carrier tape portion 84 on the terminal 80 that has been rotated to the second position by the rotating disk 10.

[0075] Then, as Figure 13 As shown, the gripping device 4 moves the gripping terminal 80 along a pre-planned path to insert the pin 82 of the gripped terminal 80 vertically into the socket 90 on the circuit board 9; simultaneously, as Figure 14 As shown, the rotating disk 10 rotates 90 degrees to rotate a terminal 80 cut from the terminal strip 8 from the first position to the second position.

[0076] Then, as Figure 15 As shown, the conveying device 2 moves the terminal strip 8 forward by one pitch so as to insert the first terminal 80 at the front end of the terminal strip 8 into a mating groove 11 of the rotating disk 10 that is aligned with it.

[0077] Then, repeat the steps described above.
