[0030] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0031] First, combine Figures 4-14 This invention describes an apparatus for automatically heat-melting nuts in narrow spaces within plastic parts, used to heat-melt copper nuts 800 into slots 701 of plastic housings 700, and has a wide range of applications.

[0032] like Figures 4-14 As shown, an embodiment of the present invention provides an automatic hot-melt nut-making device for plastic parts in a narrow space, comprising a frame 100, a conveying module 200, a positioning module 300, a handling module 400, a material feeding and heating module 500, and an assembly module 600.

[0033] Specifically, such as Figures 4-5 As shown, the conveying module 200 is mounted on the frame 100 and is used to feed in the plastic shell 700 to be heat-melted and to deliver the plastic shell 700 after heat melting. The conveying module 200 includes: a belt conveyor 201, a positioning baffle 202, an optical fiber sensor 203, and a photoelectric sensor 204.

[0034] Specifically, such as Figure 4 , 6 As shown in Figure 7, the positioning module 300 is mounted on the frame 100 to position the plastic housing 700 to be heat-melted. The positioning module 300 includes: a base plate 301, multiple columns 302, a mounting plate 303, a fixture bottom mold 304, and a clamping assembly. The base plate 301 is mounted on the frame 100; the multiple columns 302 are mounted on the base plate 301; the mounting plate 303 is mounted on top of the multiple columns 302; the fixture bottom mold 304 is mounted on top of the mounting plate 303, and the fixture bottom mold 304 is provided with a positioning block 3041; the clamping assembly is mounted on the mounting plate 303 and is used to clamp the plastic housing 700 located on the fixture bottom mold 304. The base plate 301, multiple columns 302, and mounting plate 303 are used to achieve the required height of the fixture bottom mold and for installation and fixation; the fixture bottom mold 304 and the positioning block 3041 are used to achieve precise positioning of the plastic housing 700.

[0035] Furthermore, such as Figure 4 , 6As shown in Figure 7, the clamping assembly includes a support frame 3051, a rotary cylinder 3052, and a pressure block 3053. The support frame 3051 is mounted on the top of the mounting plate 303; the rotary cylinder 3052 is mounted on the support frame 3051; and the pressure block 3053 is located at the output end of the rotary cylinder 3052. By controlling the operation of the rotary cylinder 3052, the pressure block 3053 can be driven to move, thereby achieving the clamping and loosening of the plastic housing 700. The area where the pressure block 3053 clamps the plastic housing 700 is provided with urethane adhesive.

[0036] Specifically, such as Figure 4 , 8 As shown in Figure 9, the conveying module 400 is mounted on the frame 100 and is used to convey the plastic shell 700 to be heat-melted, which is fed in by the conveying module 200, to the positioning module 300, or to convey the plastic shell 700 that has been heat-melted on the positioning module 300 to the conveying module 200. The conveying module 400 includes: a rodless cylinder 401, a conveying frame 402, a rotary cylinder 403, a three-axis cylinder 404, and an adsorption unit. The rodless cylinder 401 is mounted on the frame 100; the conveying frame 402 is mounted on the output end of the rodless cylinder 401 and moves under the drive of the rodless cylinder 401; the rotary cylinder 403 is mounted on the conveying frame 402; the three-axis cylinder 404 is mounted on the output end of the rotary cylinder 403; and the adsorption unit is mounted on the output end of the three-axis cylinder 404 for adsorbing the plastic shell 700. By controlling the operation of the rodless cylinder 401, the adsorption unit is moved to the top of the belt conveyor 201. The adsorption unit is then driven by the three-axis cylinder 404 to descend and contact the plastic housing 700 on the belt conveyor 201, completing the adsorption of the plastic housing 700. After adsorption, the three-axis cylinder 404 resets, and the rodless cylinder 401 operates again, moving the plastic housing 700 to a suitable position. The rotary cylinder 403 operates, causing the three-axis cylinder 404, the adsorption unit, and the plastic housing 700 to rotate, so that the plastic housing 700 is facing the fixture bottom mold 304. The three-axis cylinder 404 moves, placing the plastic housing 700 into the fixture bottom mold 304 for positioning. Finally, the clamping assembly completes the clamping, awaiting the insertion of the copper nut 800. After the copper nut 800 is inserted, the hot-melted plastic housing 700 can be transported onto the belt conveyor 201 and sent out by the reverse operation positioning module 300 and the conveying module 400.

[0037] Furthermore, such as Figure 4 , 8As shown in Figure 9, the adsorption unit includes: a flat plate 4051, two connecting posts 4052, a positioning plate 4053, an urethane block 4054, and multiple buffered vacuum suction cups 4055. The flat plate 4051 is located at the output end of the triaxial cylinder 404; the tops of the two connecting posts 4052 are connected to the bottom of the flat plate 4051; the top of the positioning plate 4053 is connected to the bottom of the two connecting posts 4052 and is located on one side of the bottom of the flat plate 4051. The positioning plate 4053 cooperates with the battery compartment 702 on the plastic housing 700 for positioning to ensure accurate adsorption position; the urethane block 4054 is located on the other side of the bottom of the flat plate 4051; the tops of the multiple buffered vacuum suction cups 4055 are connected to the flat plate 4051, and the bottoms of the multiple buffered vacuum suction cups 4055 penetrate through the positioning plate 4053. During adsorption, the plate 4051 moves with the operation of the triaxial cylinder 404, which in turn drives the two connecting columns 4052, the positioning plate 4053, the urethane block 4054, and the multiple buffered vacuum suction cups 4055 to move. When the positioning plate 4053 contacts the battery compartment 702 on the plastic shell 700, the movement of the triaxial cylinder 404 stops. At this time, the urethane block 4054 contacts the plastic shell 700, and the multiple buffered vacuum suction cups 4055 contact and adsorb the plastic shell 700, thereby realizing the adsorption of the plastic shell 700.

[0038] Specifically, such as Figure 4 , 10As shown in Figure 11, the feeding heating module 500 is mounted on the frame 100 and is used to heat the copper nuts 800 and discharge them one by one. The feeding heating module 500 includes: a vibratory plate 501, a linear vibrator 502, a heating frame 503, a heating block 504, a heating rod 505, a cutting block 506, a cutting cylinder 507, a cutting component 508, a material arrival detector 509, and a material pick-up sensor 510. A vibratory feeder 501 is mounted on the frame 100 and is used to orderly discharge copper nuts 800. A linear vibrator 502 is mounted on the frame 100 and has a linear vibration track 5021, one end of which is connected to the output end of the vibratory feeder 501. A heating frame 503 is mounted on the frame 100. A heating block 504 is mounted on the heating frame 503 and has a heating track 5041, one end of which is connected to the other end of the linear vibration track 5021. A heating rod 505 is mounted on the heating block 504 and is used to heat the heating block 504. The heating element is heated; the cutting block 506 is located on the heating frame 503 and connected to the heating track 5041. The cutting block 506 is provided with a cutting groove 5061; the cutting cylinder 507 is fixed on the cutting block 506; the cutting component 508 is located in the cutting groove 5061 and connected to the output end of the cutting cylinder 507. The cutting component 508 is provided with a cutting area 5081, which can accommodate a copper nut 800; the material arrival detector 509 is used to detect whether there is a copper nut 800 in the cutting area 5081; the material removal sensor 510 is used to detect whether the assembly module 600 has removed the copper nut 800 from the cutting area 5081. The copper nuts 800 are located inside the vibratory feeder 501. The vibratory feeder 501 discharges the copper nuts 800 in an orderly manner, and they are sequentially conveyed by the linear vibrating track 5021 on the linear vibrator 502 to the heating track 5041 of the heating block 504. The heating rod 505 heats the heating block 504, thereby controlling the temperature of the copper nuts 800 on the heating track 5041. The heated copper nuts 800 are then conveyed one by one to the cutting area 5081. When the material arrival detector 509 detects the heated copper nut 800 in the cutting area 5081, it will send a signal. The cutting cylinder 507 will drive the cutting component 508 to move in the cutting groove 5061, moving the copper nut 800 in the cutting area 5081 to the picking position, and finally it will be picked up by the assembly module 600. After it is picked up, the cutting cylinder 507 will reset, and the cutting component 508 will move and reset in the cutting groove 5061, so that the cutting area 5081 can receive the next copper nut 800.

[0039] Specifically, such as Figure 4 , 12As shown in Figure 13, the assembly module 600 is mounted on the frame 100 and is used to pick up the copper nuts 800 discharged one by one from the feeding heating module 500, and to heat-melt and embed the copper nuts 800 into the slots 701 of the plastic housing 700 positioned by the positioning module 300. The assembly module 600 includes: a Y-axis module 601, an X-axis module 602, a fixing plate 603, a lifting cylinder 604, a pressure plate 605, PIN pins 606, limit posts 607, and multiple guide rails 608. Y-axis module 601 is mounted on frame 100, providing driving force for Y-axis movement; X-axis module 602 is mounted on the output end of Y-axis module 601, providing driving force for X-axis movement; fixed plate 603 is mounted on the output end of X-axis module 602; lifting cylinder 604 is mounted on top of fixed plate 603; pressure plate 605 is mounted on the output end of lifting cylinder 604; PIN pin 606 is mounted on one end of pressure plate 605; limiting post 607 is mounted on fixed plate 603 and located at the bottom of pressure plate 605, used to limit the travel of pressure plate 605; multiple guide rails 608 are mounted on fixed plate 603, and pressure plate 605 is guided and slidably mounted on multiple guide rails 608, used to guide the lifting and lowering movement of pressure plate 605.

[0040] Furthermore, such as Figure 4 , 14 As shown, the head end of the PIN pin 606 is provided with a deformation groove 6061 (such as a cross groove), and the head end of the PIN pin 606 is chamfered. The diameter of the head end of the PIN pin 606 is 0.01~0.02mm larger than the inner diameter of the copper nut 800. The head of the PIN pin 606 adopts a cross-shaped elastic interference fit design and is made of iron. When picking up the copper nut 800, the PIN pin 606 is guided into the inner hole of the copper nut 800 through the chamfer. Due to the small interference fit and the use of the cross groove (which has a certain amount of elastic deformation), the copper nut 800 can be picked up without damaging the inner hole of the copper nut 800 during interference fit picking.

[0041] Working principle: An external robotic arm picks up the plastic shell 700 to be heated and places it at the head end of the belt conveyor 201. After the photoelectric sensor 204 detects the presence of the plastic shell 700, the plastic shell 700 is conveyed to the tail end of the belt conveyor 201 and positioned by the positioning baffle 202. After positioning, the fiber optic sensor 203 detects the plastic shell 700 and sends a signal. By controlling the operation of the rodless cylinder 401, the adsorption unit is moved to the top of the belt conveyor 201. The adsorption unit is driven to descend by the three-axis cylinder 404 and contact the plastic housing 700 on the belt conveyor 201 to complete the adsorption of the plastic housing 700. After adsorption is completed, the three-axis cylinder 404 is reset, and the rodless cylinder 401 runs again, moving the plastic housing 700 to a suitable position. The rotary cylinder 403 runs, driving the three-axis cylinder 404, the adsorption unit, and the plastic housing 700 to rotate, so that the plastic housing 700 is facing the bottom mold 304 of the fixture. The three-axis cylinder 404 moves to place the plastic housing 700 into the bottom mold 304 of the fixture for positioning. Finally, the clamping component completes the clamping, waiting for the insertion of the copper nut 800. The copper nuts 800 are discharged in an orderly manner by the vibrating plate 501 and sequentially conveyed to the heating track 5041 of the heating block 504 by the linear vibrator 502's linear track 5021. The heating block 504 is heated by the heating rod 505, so that the heating block 504 heats the copper nuts 800 on the heating track 5041 with controlled temperature. The heated copper nuts 800 are conveyed one by one to the cutting area 5081. When the material arrival detector 509 detects the heated copper nuts 800 in the cutting area 5081, it will send a signal, and the cutting cylinder 507 will drive the cutting part 508 to move in the cutting groove 5061, moving the copper nuts 800 in the cutting area 5081 to the picking position. The Y-axis module 601 and X-axis module 602 operate, driving the fixed plate 603, lifting cylinder 604, pressure plate 605, and PIN pin 606 to move, so that the PIN pin 606 is located at the top of the copper nut 800. The lifting cylinder 604 retracts, the fixed plate 603 and PIN pin 606 descend, and the PIN pin 606 is inserted into the inner hole of the copper nut 800. The lifting cylinder 604 rises, and the PIN pin 606 waits for the copper nut 800 to rise. The material sensor 510 detects the copper nut 800. After detecting the copper nut 800, the Y-axis module 601 and X-axis module 602 operate, moving the PIN pin 606 and copper nut 800 to the top of the slot 701 of the positioned plastic shell 700. The lifting cylinder 604 retracts, and the PIN pin 606 descends, heat-melting and embedding the copper nut 800 into the slot 701 of the plastic shell 700, completing the heat melting. After the plastic shell 700 has been heat-melted, it is moved by the handling module 400 to the conveying module 200 for delivery. After delivery, the above steps are repeated to heat-melt the next plastic shell 700.

[0042] Above, refer to Figures 4-14 An apparatus for automatically heat-melting nuts in narrow spaces within plastic parts according to an embodiment of the present invention is described, which can automatically insert copper nuts 800 into slots 701 of plastic housing 700, thereby improving assembly efficiency and reducing manual labor.
