[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings, wherein the same components are represented by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the accompanying drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0026] Reference Figure 1-8As shown, a general-purpose hot melt nut machine includes a frame 1, a mounting seat 2 disposed on the frame 1 for limiting the installation of plastic parts, a feeding vibratory plate for conveying nuts, a robotic arm 3 for clamping nuts into pre-installed holes on plastic parts, and a heating and pressing component 4 for heating nuts and hot melting them into place. The feeding vibratory plate, the robotic arm 3, and the heating and pressing component 4 are all known technologies and can be designed in a conventional manner.

[0027] The vibratory feeder includes a feeding guide rail 5, the end of which is correspondingly positioned with the robotic arm 3. A mounting base 2 is slidably connected to a frame 1. The frame 1 is equipped with a lateral moving component 6 for driving the mounting base 2 laterally and a longitudinal moving component 7 for driving the mounting base 2 longitudinally. During the sliding motion of the mounting base 2 on the frame 1, it includes an upper nut position 11 located below the robotic arm 3, a heat-melting position 12 located below the heating and pressing component 4, and a transition position 13 located between the upper nut position 11 and the heat-melting position 12. The lateral moving component 6 can drive the mounting base 2 to reciprocate between the transition position 13 and the heat-melting position 12, and the longitudinal moving component 7 can drive the mounting base 2 to reciprocate between the transition position 13 and the upper nut position 11. The robotic arm 3 can place the nut fed by the feeding guide rail 5 onto the plastic part located at the upper nut position 11, and then the heating and pressing component 4 heat-melts the nut located at the heat-melting position 12 into place.

[0028] One set of robotic arm 3 is provided corresponding to the longitudinal moving component 7. Two sets of heating and pressing components 4 and lateral moving components 6 are provided corresponding to each other. The two sets of heating and pressing components 4 and lateral moving components 6 are located on opposite sides of the transition position 13. Two mounting seats 2 are also provided, each corresponding to one of the two lateral moving components 6. The two sets of heating and pressing components 4 perform the nut heat-melting operation in conjunction with one set of robotic arm 3 to perform the nut placement operation, which can effectively increase the efficiency of the heat-melting work.

[0029] When the mounting seat 2 is located at the upper nut position 11, the robot arm 3 can place the nut conveyed by the feeding guide rail 5 onto the plastic part located at the upper nut position 11. The longitudinal moving component 7 drives the mounting seat 2 to slide from the upper nut position 11 to the transfer position 13, and then the transverse moving component 6 drives the mounting seat 2 to slide from the transfer position 13 to the heat-melting position 12. After that, the heating and pressing component 4 performs the nut heat-melting operation. Finally, the heat-melted plastic part is removed, and the plastic part to be heat-melted is placed on it. It is then moved to the upper nut position 11 again, which realizes the automatic heat-melting operation of the heat-melting nut machine. The degree of automation is high, which is conducive to improving processing efficiency and effectively reducing processing costs. In addition, the robot arm 3 is equipped with two heating and pressing components 4, which is conducive to the continuous operation of the heat-melting nut by the two heating and pressing components 4, which is conducive to further improving processing efficiency and greatly improving the flexibility and applicability of the heat-melting nut machine.

[0030] The lateral moving component 6 includes a lateral cylinder 61 capable of driving the mounting base 2 to slide, and a connecting component 62 detachably connected between the movable end of the lateral cylinder 61 and the mounting base 2. The connecting component 62 includes a T-shaped connecting block 621 disposed at the movable end of the lateral cylinder 61, and a T-shaped groove 622 formed on the mounting base 2 that can slide and connect with the T-shaped connecting block 621. At least one end of the T-shaped groove 622 is through-hole, and the direction in which the T-shaped connecting block 621 slides within the T-shaped groove 622 is the same direction in which the longitudinal moving component 7 drives the mounting base 2 to slide. The connecting component 62, which cooperates with the T-shaped connecting block 621 and the T-shaped groove 622, enables the lateral cylinder 61 to drive the mounting base 2 to slide laterally when the two are connected. Furthermore, when the mounting base 2 is in the transition position 13, the T-shaped connecting block 621 can slide out from one end of the T-shaped groove 622 during the longitudinal sliding of the mounting base 2 by the longitudinal moving component 7. The structural design is ingenious and reasonable, cleverly realizing both longitudinal and lateral sliding of the mounting base 2.

[0031] In addition, when the longitudinal moving component 7 drives the mounting seat 2 to slide from the upper nut position 11 to the transition position 13, the T-shaped connecting block 621 can also slide into the T-shaped groove 622 from one end, which facilitates the effective connection between the T-shaped connecting block 621 and the mounting seat 2.

[0032] The longitudinal moving component 7 includes a sliding seat 71 for receiving the mounting base 2 and a longitudinal driver 72 for moving the sliding seat 71. The sliding seat 71 has a mounting groove 711 for the mounting base 2 to slide into. The mounting groove 711 extends through both ends, facilitating the sliding of the two mounting bases 2 located on either side of the sliding seat 71. The bottom surface of the mounting groove 711 is at the same height as the bottom surface of the sliding seat 71, ensuring the mounting base 2 slides smoothly into the mounting groove 711. During the sliding process, the transverse cylinder 61 pushes the mounting base 2 horizontally into the mounting groove 711. During the sliding process driven by the longitudinal driver 72, the T-shaped connecting block 621 can detach from or slide into the T-shaped sliding groove 622. The sliding seat 71 facilitates the receiving of the mounting base 2 and allows for easy switching between transverse and longitudinal sliding of the mounting base 2.

[0033] The transverse cylinder 61 includes a first transverse cylinder 63 capable of rapidly reciprocating the mounting seat 2 between the transition position 13 and the hot-melt position 12, and a second transverse cylinder 64 capable of rapidly reciprocating the mounting seat 2 away from the transition position 13 at the hot-melt position 12. The transverse moving component 6 also includes a mounting slide 65 slidably connected to the frame 1 for mounting the first transverse cylinder 63. The first transverse cylinder 63 can rapidly reciprocate the mounting seat 2 between the transition position 13 and the hot-melt position 12, greatly improving the processing efficiency of the hot-melt nut machine. The addition of the second transverse cylinder 64 can quickly move the mounting seat 2 away from the mounting seat 2 to the disassembly and assembly positions located on both sides of the hot-melt nut machine. This facilitates the removal of the hot-melt plastic parts and the placement of the plastic parts to be hot-meltd, and does not affect the operation of the robot arm 3 and the longitudinal moving component 7 during the disassembly and assembly process, which is conducive to further improving the processing efficiency of the hot-melt nut machine.

[0034] The mounting base 2 is detachably and fixedly connected with a limiting frame 21 for limiting plastic parts. As part of the hot melt nut machine, the mounting base 2 needs to be equipped with a detachable limiting frame 21 to accommodate the limiting installation of plastic parts of different specifications and sizes, thereby improving the flexibility and applicability of the hot melt nut machine.

[0035] The limiting frame 21 is movably connected to locking claws 22 that can secure the plastic part. Two locking claws 22 are arranged symmetrically on opposite sides of the limiting frame 21, with the locking claws 22 located inside the plastic part. The limiting frame 21 is provided with elastic elements 23 that can press the locking claws 22 against the inner wall of the plastic part. The two locking claws 22 in one set are fastened to the two opposite inner walls of the plastic part, which helps to improve the locking firmness of the two locking claws 22 at that point. Moreover, with two locking claws 22 as a set, multiple sets of locking claws 22 can be provided on one limiting frame 21, which can effectively improve the locking firmness of the limiting frame 21 for the plastic part.

[0036] The limiting frame 21 is equipped with a guide rod 24 for the locking claws 22 to slide into the limiting frame 21. The elastic element 23 is a spring and is sleeved on the guide rod 24. The spring can simultaneously push the locking claws 22 at both ends to press against the inner wall of the plastic part. The locking claws 22 are axially slidably connected to the guide rod 24. When the plastic part is fastened to the limiting frame 21, the edge of the shell-shaped opening of the plastic part will push the locking claws 22 to slide into the limiting frame 21. During this process, the locking claws 22 compress the spring, so that the spring can press against the inner wall of the plastic part through the locking claws 22, thereby achieving the limiting of the plastic part. In this limiting scheme, the pushing action of the locking claws 22 at both ends by a spring can also help improve the centering and limiting effect of the two locking claws 22 on the limiting frame 21 on the plastic part, thereby improving the positioning accuracy of the limiting frame 21 on the plastic part.

[0037] The heating and pressing component 4 includes a columnar heat-melting element 41, a heat-melting frame 42 that is lifted and slidably connected to the frame 1 for mounting the heat-melting element 41, and a lifter 43 that is mounted on the frame 1 for driving the heat-melting frame 42 to lift and slide. The heat-melting element 41 is a known technology and can be designed in a conventional manner. An adjusting arm 44 for mounting the heat-melting element is slidably connected to the heat-melting frame 42. One end of the adjusting arm 44 is provided with two jaws 441 for clamping the heat-melting element 41. A fastening bolt is provided between the two jaws 441 to clamp and fix the heat-melting element 41. The other end of the adjusting arm 44 is provided with a transverse groove 442 that can adjust and slide with the heat-melting frame 42. The heat-melting frame 42 is provided with a longitudinal groove 421 that can adjust and slide with the adjusting arm 44. The length direction of the transverse groove 442 intersects the length direction of the longitudinal groove 421. The heat-melting frame 42 and the adjusting arm 44 can be adjusted and set by adjusting bolts. The hot melt component 41 is columnar and is installed in an adjustable position with the adjusting arm 44 by two clamps 441 and fastening bolts. This allows for easy adjustment of the working height of the hot melt component 41. The horizontal waist groove 442 and the vertical waist groove 421 can be used with the adjusting bolts to flexibly adjust the horizontal and vertical positions of the adjusting arm 44 in the hot melt frame 42, which greatly improves the flexibility and applicability of the heating and pressing component 4. Therefore, this hot melt nut machine only needs to replace the positioning fixture used for product positioning, namely the limiting frame 21 in this application, to achieve nut hot melting of plastic parts of different specifications, which greatly improves the versatility of the hot melt nut machine.

[0038] The hot melt frame 42 is equipped with a pressing arm 45 that can press down the plastic part. The pressing arm 45 can be adjusted and slidably arranged along the lifting direction of the hot melt frame 42. Preferably, the pressing arm 45 is designed to elastically press down on the plastic part, and preferably, the pressing arm 45 can press down the plastic part before the hot melt part 41 contacts the nut, which helps to improve the stability of the plastic part during operation and improves the yield of the hot melt nut machine.

[0039] The robotic arm 3 includes a cylinder gripper 31 for gripping a nut, a horizontal slide block 32 that is horizontally slidably connected to the frame 1, a lifting slide block 33 that is vertically slidably connected to the horizontal slide block 32 and used for mounting the cylinder gripper 31, a horizontal drive component 34 that is mounted on the frame 1 to drive the horizontal slide block 32 to slide along the width direction of the plastic part on the frame 1, and a lifting drive component 35 that is mounted on the horizontal slide block 32 to drive the lifting slide block 33 to slide vertically. Both the horizontal drive component 34 and the lifting drive component 35 include a drive motor 36 and a drive screw 37. Limit sensors 38 are provided between the horizontal slide block 32 and the frame 1 and between the lifting slide block 33 and the horizontal slide block 32. The cylinder gripper 31 is a known technology and adopts a common design. The drive motor 36 can be a stepper motor or a servo motor, so that the transmission of the horizontal drive component 34 and the lifting drive component 35 can achieve accurate positioning, which is convenient for placing the nut in place. In addition, the transmission of the longitudinal driver 72 is also preferably achieved through the drive motor 36 and the drive screw 37, which helps to improve the positioning accuracy of the sliding seat 71.

[0040] During implementation, the end of the feeding guide rail 5 can be located in the middle of the width of the plastic part, so that the robot arm 3 can use the end of the feeding guide rail 5 as the base point to insert nuts into the pre-installed holes on both sides of the plastic part respectively. Then, the longitudinal driver 72 drives the plastic part to move along its length direction, so that the robot arm 3 can insert nuts into the pre-installed holes at different positions on both sides of the plastic part.

[0041] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
