Description

Technical Field

[0001] This utility model relates to the field of plug manufacturing technology, specifically a material transfer device for plug injection molding assembly and testing. Background Technology

[0002] Plug injection molding assembly is a production process that combines conductive components (such as copper pins) with insulating plastic through injection molding. First, the pins are pre-treated and cleaned, then fixed in the mold. Molten plastic is then injected and wrapped around the pins. After cooling and solidification, burrs are removed. Then, functional tests such as insulation resistance and withstand voltage are performed, as well as visual inspection, to ensure safety and compliance. The process covers material preparation, insert injection molding, and post-processing. Parameters such as temperature and pressure must be controlled to avoid shrinkage, detachment, and other problems. The products meet national standards, American standards, and other regional standards and are widely used in home appliances, electronic equipment, and other fields. In recent years, there has been a trend towards environmentally friendly materials and automated production to improve efficiency and safety.

[0003] Currently, when inspecting the injection molding assembly effect of plugs, a transfer device such as a robotic arm is needed to move the injection-molded plugs to the testing equipment for inspection of various aspects of the plugs. When using a robotic arm to deliver the plugs to the testing area, rubber pads are placed at the unloading point to prevent damage to the plugs. However, when the plugs are lowered, they collide with the rubber pads, which can easily cause significant positional displacement, affecting subsequent inspections of the plugs.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a new technical solution: a material transfer device for plug injection molding assembly testing, including a mounting platform 1, a robotic arm 2 fixedly mounted on the upper surface of the mounting platform 1, an adsorption plate 3 fixedly mounted on the lower surface of the working end of the robotic arm 2, and a mounting plate 4 fixedly mounted on the rear surface of the adsorption plate 3.

[0024] An auxiliary feeding mechanism is mounted on the mounting plate 4. The auxiliary feeding mechanism includes two movable plates 5 and two guide rubber pads 6. A storage groove 7 is provided on the lower surface of the mounting plate 4. Both ends of the storage groove 7 are open. An installation box 8 is slidably installed inside the storage groove 7. The lower end of the installation box 8 is open. Both movable plates 5 are slidably installed on the lower surface of the installation box 8. The front ends of both movable plates 5 extend to the suction plate 3. The two guide rubber pads 6 are respectively fixedly installed on the front ends of the adjacent surfaces of the two movable plates 5.

[0025] Furthermore, the auxiliary feeding mechanism also includes two rectangular plates 9, which are slidably installed inside the mounting box 8. Two-way threaded rods 10 are rotatably installed on the left and right inner walls of the mounting box 8. Both rectangular plates 9 are threadedly connected to the two-way threaded rods 10, and the two rectangular plates 9 are fixedly connected to the two movable plates 5 respectively.

[0026] Furthermore, by moving two plates 5, two guide rubber pads 6 are brought close to the plug to be dropped, so that the triangular plates of the two guide rubber pads 6 guide the falling trajectory of the plug, preventing the plug from falling or colliding with the rubber pad at the detection station and causing a large deviation, thereby improving the detection accuracy of the plug in subsequent detection and improving the detection effect.

[0027] Furthermore, a motor 11 is fixedly installed on the right surface of the mounting box 8. The output end of the motor 11 rotates through the interior of the mounting box 8, and the motor 11 is fixedly connected to the bidirectional threaded rod 10.

[0028] Furthermore, connecting plates 12 are fixedly installed on both the left and right ends of the lower surface of the mounting box 8, and guide rods 13 are fixedly installed on the adjacent surfaces of the two connecting plates 12. The two movable plates 5 are slidably connected to the outer surface of the guide rods 13.

[0029] Furthermore, two electric push rods 14 are fixedly installed on the upper surface of the mounting plate 4. The telescopic ends of the two electric push rods 14 slide through the interior of the storage slot 7, and the two electric push rods 14 are fixedly connected to the mounting box 8.

[0030] Furthermore, a protective rubber pad 15 is fixedly installed on the lower surface of the adsorption plate 3, and a connecting pipe 16 is fixedly installed on the upper right surface of the adsorption plate 3. The connecting pipe 16 is connected to the interior of the adsorption plate 3.

[0031] Furthermore, when using this transfer device, the robotic arm 2 moves, causing the adsorption plate 3 to move above the plug to be tested. The protective rubber pad 15 lightly touches the surface of the plug, the vacuum pump starts, and a negative pressure is formed inside the adsorption plate 3 through the connecting pipe 16, adsorbing and fixing the plug. At this time, the plug is in contact with the protective rubber pad 15 to avoid hard collision. The robotic arm 2 carries the adsorbed plug to the rubber pad of the testing station, adjusts the position so that the plug is aligned with the target landing point, and the two electric push rods 14 are activated, pushing the mounting box 8 to extend downward from the storage slot 7. At this time, the moving plate 5 and the guide rubber pad 6 descend with the mounting box 8 to both sides of the plug. The motor 11 drives the bidirectional threaded rod 10 to rotate, causing the two rectangular plates 9 to move left and right along the bidirectional threaded rod 10, thereby pushing the plug. The moving plate 5 slides inward, bringing the triangular plates of the two guide rubber pads 6 close to both sides of the plug. The vacuum pump stops working, the suction plate 3 releases the negative pressure, and the plug falls under the action of gravity. At this time, the triangular plates of the guide rubber pads 6 restrict its horizontal displacement, ensuring that the plug falls vertically into the center of the rubber pad. The adjacent surfaces of the two guide rubber pads 6 are arranged with triangular plates running vertically. The triangular plates of the guide rubber pads 6 are arranged vertically, guiding the plug to fall vertically. At the same time, the triangular plates increase the difficulty of moving the plug back and forth. After the plug is placed, the motor 11 reverses, the moving plate 5 drives the guide rubber pads 6 to return to both sides of the mounting box 8, the electric push rod 14 retracts, and the mounting box 8 is returned to the storage groove 7, entering the next round of transfer cycle.
