[0041] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0042] like Figures 1 to 3 As shown, the utility model provides a pin insertion device for terminal pins, including a frame 10 and a feeding mechanism 20, on which a feeding channel 21 for placing pins 80 is formed, and the pins 80 are in the shape of a "7", and the short side and the long side of the pins 80 are perpendicular to each other and are in the shape of a round tube. A needle-loading jig 30 is fixedly arranged on the frame 10, and a needle-passing channel 31 for the pins 80 to pass through is arranged on the needle-loading jig 30, and the shape of the needle-passing channel 31 is adapted to the "7" shape of the pins 80. The end of the feeding channel 21 abuts against one end face of the needle-loading jig 30, and the pins 80 can smoothly enter the inside of the needle-loading jig 30 after being transported through the hanging plane of the feeding channel 21. The feeding mechanism 20 includes a vibration plate 22 and a feeding channel 21, which are located in the shape and center of gravity of the pins 80, and the working plane of the feeding channel 21 is set in a "V" shape, which is also conducive to improving the feeding efficiency.

[0043] The frame 10 is provided with a straitening mechanism 40, which is used to move the pins 80 discharged through the needle channel 31 to the top of the needle fixture 30. And the originally tilted pins 80 are swung to an upright position (the long side of the pins 80 is perpendicular to the ground) to facilitate the subsequent mechanism to clamp.

[0044] The rack 10 is provided with a material discharging platform 50 for fixing terminals or mold jigs. In actual production, the pins 80 are inserted into the terminals of electrical components to form an intermediate piece for circuit connection. In order to increase work efficiency, the pins 80 can be inserted into the mold jig first, and then several terminals are placed on the entire mold jig by positioning, and finally the pins 80 are fixed on the terminals through other processes, and several terminals are taken out at the same time.

[0045] A pin insertion mechanism 60 is movably provided on the frame 10, and its function is to clamp the pins 80 transferred by the alignment mechanism 40, and move and insert them into the final terminal or mold fixture.

[0046] The above are the mechanical components required for the entire pin insertion device to achieve its functions and purposes.

[0047] like Figure 5 and Figure 6 As shown, the straightening mechanism 40 includes a fixed block 41, a swing block 42 is hinged on the fixed block 41, an adsorption block 43 for adsorbing the pin 80 is fixedly arranged on the swing block 42, a connecting rod 44 is hinged on the swing block 42, one end of the connecting rod 44 is hinged on the swing block 42, and the other end of the connecting rod 44 is hinged on the driving block 45, the driving block 45 is connected to the second cylinder 46 to provide and provide power for the driving block 45, the second cylinder 46 is fixedly connected to the cylinder fixing seat 47, the cylinder fixing seat 47 is connected to the frame 10, and its output end is horizontally connected to the driving block 45. The working principle of this part is that the second cylinder 46 drives the driving block 45 to extend and retract left and right when working, thereby driving the swing block 42 to move through the connecting rod 44 hinged at both ends at the same time, because the swing block 42 is also hinged on the fixed block 41, the circular swing of the swing block 42 is realized at the center point of the hinge of the fixed block 41. The position of the needle outlet of the needle-installing jig 30 and the arc motion path of the swing block 42 above the needle-installing jig 30 realize the transfer of the pin 80 and the uprighting of the pin 80.

[0048] The adsorption block 43 is close to the needle outlet of the needle fixture 30. A negative pressure generating mechanism is arranged inside the adsorption block 43 and is connected to the negative pressure tube 49. The negative pressure tube 49 is connected to the receiving groove 431. In this way, the pin 80 will be sucked. In order to make the pin 80 more fixed and not fall off during the transfer process, the adsorption block 43 is provided with a receiving groove 431 for accommodating the pin 80. This also solves the problem of the pin 80 being stuck by friction during the transfer process because the adsorption block 43 and the needle fixture 30 are close to the end surface. A first position sensor 48 is arranged on the cylinder fixing seat 47 and the driving block 45 to detect and control the movement stroke.

[0049] like Figure 1 and Figure 3 As shown, the needle insertion mechanism 60 includes a needle moving assembly 62 and a grasping and inserting assembly 61 .

[0050] like Figure 8 As shown, the grabbing and inserting assembly 61 includes a first fixed seat 612, a clamping claw 614 is fixedly arranged below the first fixed seat 612, a third cylinder 611 is fixedly arranged above the first fixed seat 612, and a pressing rod 613 passing through the clamping claw 614 for compacting the pins 80 is fixedly arranged at the output end of the third cylinder 611. The function of this assembly is to clamp the pins 80 transferred by the adsorption block 43, and when the object to be inserted needs to be compacted, the pressing rod 613 assists in compacting under the drive of the third cylinder 611. A pressing needle groove 615 for the pressing rod 613 to pass through is arranged in the middle of the clamping claw 614.

[0051] In order to prevent the position or height of the pin 80 from deviating during the transfer of the pin 80 by the adsorption block 43, which results in the inability of the clamp to clamp according to the normal setting, a first cylinder 32 is provided under the needle fixture 30, and the output shaft of the first cylinder 32 is provided with a push rod 34 for lifting the pin 80, and a clearance groove 33 for the output shaft of the first cylinder 32 to pass through is provided on the needle fixture 30. By setting the telescopic stroke of the first cylinder 32, it is further ensured that the pin 80 reaches the preset position, which facilitates the clamp to clamp accurately in place.

[0052] The needle moving assembly 62 includes a fourth cylinder 621, and the output shaft of the fourth cylinder 621 is fixedly connected to a stroke plate 623, and the stroke plate 623 is fixedly connected to a second fixed seat 622, and the second fixed seat 622 is fixedly connected to the first fixed seat 612. The function of this assembly is to move the grabbing and inserting assembly 61 above the object to be inserted. A second position sensor 63 is fixedly arranged below the second fixed seat 622 to detect and control the movement stroke. The up and down movement is achieved by the fourth cylinder 621. The needle moving assembly 62 is fixedly provided with a driving motor 11 on the frame 10, and the output end of the driving motor 11 is connected to a screw rod 12, and the screw rod 12 is fixedly connected to the needle moving assembly 62, so that the left and right movement of the needle moving assembly 62 is achieved.

[0053] like Figure 2 As shown, the material discharging platform 50 includes a third fixed seat 53, a top block 54 for fixing the terminal or mold fixture is fixedly arranged on one side of the third fixed seat 53, and a pair of fifth cylinders 51 are arranged on the other side of the third fixed seat 53, and a top plate 52 is fixedly installed on the output shaft of the fifth cylinder 51. After the terminal or mold fixture is placed, the top block 54 and the top plate 52 cooperate and clamp it, and the third fixed seat 53 can move forward and backward, so that the pins 80 can be efficiently and quickly inserted into the terminal or mold fixture in batches.

[0054] The frame 10 is also provided with an illumination member 70. Since the pins 80 are very small and made of metal, strong light is needed to reflect the pins 80 so as to reduce the harm caused by the improper position of the pins 80 during startup or maintenance in important areas. In addition, the feeding mechanism 20, the feeding channel 21, the needle loading fixture 30, the alignment mechanism 40 and the needle insertion mechanism 60 are mirror-set on both sides of the frame 10. The two groups of equipment are divided into two groups to work, which further increases the work efficiency.

[0055] The working principle and process of the pin insertion device are as follows:

[0056] The power and pneumatic of the equipment are turned on, and the left and right direct vibrations send the pins 80 to the designated position. The left and right vibration plates 22 send the pins 80 into the feeding channel 21. At this time, the terminal or mold fixture is placed on the material discharge platform 50 of the machine. When the photoelectric sensing detects the terminal or mold fixture, the fifth cylinder 51 will lock the terminal or mold fixture in place and send it to the needle loading position. When the pin 80 is sent to the needle loading fixture 30, the pin 80 is sucked by the adsorption block 43 by manual and inch motion, and the pin 80 is transported to the top of the needle loading fixture 30 through the straightening mechanism 40. When the push rod 34 lifts the pin 80 by one third through the first cylinder 32, the clamping claw 614 of the grabbing assembly 61 clamps the pin 80 and puts it into the terminal or mold fixture. When the clamping claw 614 is pneumatically released, the pressure rod 613 presses the pin 80 down to send the pin 80 into the terminal or mold fixture. At this time, the automatic continuous cycle operation is started.

[0057] In summary, the utility model conveys the pins 80 to the needle loading jig 30 through the feeding mechanism 20, transfers the pins 80 discharged from the needle loading jig 30 to the top of the needle loading jig 30 by the straightening mechanism 40, then clamps them by the grabbing and inserting assembly 61, and transfers the pins 80 to the terminal or mold jig under the action of the needle moving assembly 62, and finally compacts and inserts them by the pressing rod 613.

[0058] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
