Technical Field
[0001] This utility model relates to the field of injection molding technology, specifically to a robotic arm for removing injection-molded building block toy components. Background Technology
[0002] Building blocks are typically solid plastic toys that can be arranged in various ways to form different architectural shapes. Building blocks play a significant role in children's intellectual development and are also a way to improve their hand-eye coordination. The production of building blocks usually involves injection molding. However, because injection-molded building blocks have splicing grooves at the bottom, and the upper end of the lower mold corresponds to these grooves, it is difficult to add ejector pins to the lower mold for ejecting the injection-molded building blocks. This makes demolding a major challenge. Furthermore, adding ejector pins requires corresponding mold design, resulting in high mold development and manufacturing costs. If a robotic arm is used to remove the injection-molded building blocks, the robotic arm is expensive, requires regular maintenance, and is difficult to insert between the upper and lower molds for operation.

[0021] like Figure 1-3 As shown, a robotic arm for removing injection-molded building block toys includes a first movable frame, a second movable frame, a crossbeam 5, and an adsorption structure. The crossbeam 5 is connected between the first and second movable frames and can move longitudinally and vertically between them. The adsorption structure is installed in the crossbeam 5 and is used to adsorb the injection-molded part. The lower end of the adsorption structure has an adsorption groove 701 protruding from the lower end face of the crossbeam 5. The shape of the adsorption groove 701 is adapted to the upper end face of the injection-molded part. The adsorption groove 701 has a gas channel 702 leading to the side of the adsorption structure, which can be connected to an external air pump to provide positive and negative pressure to the adsorption groove 701 to facilitate the adsorption and release of the injection-molded part. At the same time, the gas channel 702 is located on the side of the adsorption structure, which can save installation space and avoid mutual interference between the crossbeam 5 and the adsorption structure in the compact space when they enter the injection mold, thus affecting the normal gripping of the injection-molded part.
[0022] In the above embodiments, the first movable frame includes a first base 1, a first slide 3, and a first vertical moving component 12. The second movable frame includes a second base 2, a second slide 4, and a second vertical moving component 13. The first slide 3 and the second slide 4 are slidably connected to the upper ends of the first base 1 and the second base 2, respectively. The first vertical moving component 12 and the second vertical moving component 13 are respectively mounted on the first slide 3 and the second slide 4. The two ends of the crossbeam 5 are respectively connected to the output ends of the first vertical moving component 12 and the second vertical moving component 13. The second base 2 is provided with a longitudinal moving component 11. The output end of the longitudinal moving component 11 is connected to the second slide 4. The longitudinal moving component 11 can be driven by a motor and a lead screw. The motor is mounted on the second base 2, and one end of the lead screw is connected to the output end of the motor. The lead screw is connected to the second slide 4 for transmission, accurately driving the longitudinal movement of the second slide 4. The first vertical moving component 12 and the second vertical moving component 13 can be driven by a cylinder or by a motor and a lead screw. The first slide block 3 and the second slide block 4 are respectively provided with a first vertical groove and a second vertical groove. The two ends of the crossbeam 5 are slidably connected to the first vertical groove and the second vertical groove respectively. The first vertical groove and the second vertical groove together provide a limit and guide for the vertical sliding of the crossbeam 5, keeping its vertical movement stable. The first slide block 3 and the second slide block 4 are both provided with limiting holes 15 on their sides, and the crossbeam 5 is provided with insertion holes 16 on its side. Pins 17 can be inserted into the limiting holes 15 and the insertion holes 16 at the same time. The pins 17 can be set one above the other on the top and one below the crossbeam 5, providing a safe limit for the vertical movement of the crossbeam 5, preventing it from exceeding its stroke and causing the crossbeam 5 and the adsorption structure to collide with the mold or injection molded part. The crossbeam 5 is equipped with a transverse moving component 14. The output end of the transverse moving component 14 is connected to the adsorption structure and is used to adjust the precise position of the adsorption structure to ensure that the adsorption groove 701 can be aligned with the injection molded part. The transverse moving component 14 can also adopt a precise transmission method of motor and lead screw, in which the lead screw is rotatably installed in the crossbeam 5, and the motor in the crossbeam 5 drives the lead screw to make the lead screw and the adsorption structure connected in transmission.
[0023] In the above embodiment, the adsorption structure includes a connecting plate 6 and an adsorption plate 7. The connecting plate 6 is installed in the crossbeam 5, and the adsorption plate 7 is installed at the lower end of the connecting plate 6, protruding from the lower end face of the crossbeam 5. The adsorption groove 701 is located at the lower end of the adsorption plate 7, and the gas channel 702 connects from the upper end of the adsorption groove 701 to the side of the adsorption plate 7. The adsorption plate 7 is a custom-made part, machined or laser-processed according to the model of the injection molded product, and then drilled to form the gas channel 702. Finally, it is locked at the lower end of the connecting plate 6. This method has low cost and strong adaptability. The upper end face of the adsorption groove 701 is provided with a spring 8. When the injection molded part is adsorbed in the adsorption groove 701, the injection molded part will compress the spring 8 under the action of negative pressure. When the injection molded part is grasped and moved to the unloading area, the injection molded part is more easily detached from the adsorption groove 701 under the action of positive pressure and spring 8. Spring 8 provides assistance for unloading. One end of the gas channel 702 is provided with a gas valve 9 for easy connection to a gas pipe. The side of the crossbeam 5 is equipped with a fixing clip 10 to clamp the air pipe, allowing it to be laid along the side of the crossbeam 5 and avoiding interference with other structures. The upper surface of the connecting plate 6 is flush with the crossbeam 5, further ensuring the compactness of its structure.
[0024] Description of the working principle of this utility model:
[0025] The first base 1 and the second base 2 are respectively mounted on both sides of the injection molding equipment, and the first slide 3 and the second slide 4 are respectively installed. The crossbeam 5 is connected to the lower end of the cylinder of the first vertical moving component 12 and the second vertical moving component 13 respectively. After adjusting the position of the first base 1 and the second base 2, they are installed and fixed with expansion screws. The position of the adsorption structure is adjusted by the motor and lead screw of the horizontal moving component 14. The vertical movement range of the crossbeam 5 is determined by the pin 17 so that the adsorption tank 701 can be aligned with the injection molded part. Specifically, the circular adsorption tank 701 is aligned and matched with the circular structure at the top of the injection molded building block toy. The location of the robot arm picking up the material is recorded by the external controller. It is also necessary to set up a material discharge point, that is, to set up a collection box on the side of the injection molding equipment and put the injection molded building block toy in the adsorption tank 701 into it. After the injection molding equipment completes the injection molding of the building block toy, the crossbeam 5 located on the side of the mold moves between the upper and lower molds under the control of the longitudinal moving component 11. At this time, the suction groove 701 of the suction plate 7 is directly opposite the circular structure at the top of the building block toy. The cylinders of the first vertical moving component 12 and the second vertical moving component 13 press down on the crossbeam 5 simultaneously, so that the circular structure of the building block toy is just embedded in the suction groove 701 and the spring 8 is compressed. The external air pump connected to the air valve 9 generates negative pressure in the suction groove 701, firmly sucking up the building block toy. Then, the cylinders of the first vertical moving component 12 and the second vertical moving component 13 lift the crossbeam 5 simultaneously. The motor and lead screw of the longitudinal moving component 11 drive the first slide 3 and the second slide 4 to move longitudinally, so that the building block toy moves to the top of the collection box. The external air pump applies positive pressure, which, together with the spring 8, pushes the building block toy out, realizing the process of suction picking and pumping air ejection of material by the robotic arm, which is convenient and fast. It should be noted that the crossbeam 5 used in this utility model is long and flat, and the adsorption plate 7 is relatively thin, so the overall height space occupied is small, which makes it easy for the crossbeam 5 and the adsorption plate 7 to move between the upper mold and the lower mold. This realizes the function of a robotic arm to pick up and put down materials in a compact injection molding equipment. In addition, the manufacturing cost of this utility model is low. Compared with intelligent robotic arms, it saves enterprises a lot of costs while achieving the same function.
[0026] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
