Description

Technical Field

[0001] The present invention relates to the technical field of hot melt nuts, and specifically to a high-precision automatic hot melt nut device. Background Art

[0002] The hot melt nut device is a special automatic device for fixing hot melt nuts to plastic or other material injection molded parts. It realizes the tight combination of the nut and the injection molded part through hot melt processing, thereby improving the firmness and reliability of the component.

[0003] In the prior art, when performing hot melt on an injection molded part, the injection molded part is prone to offset. The offset injection molded part is likely to cause deviation of the hot melt nut, resulting in damage.

[0004] In order to overcome the above deficiencies, the Chinese patent of the prior art (application number 202222403531.8) discloses an automatic hot melt nut implanting device, a frame and a fixed fixture for positioning products. A nut hot melt implanting mechanism and a nut feeding device are installed above the fixed fixture on the frame. The nut hot melt implanting mechanism includes a first linear module arranged vertically, a pressing mechanism, a heating module and a side pushing mechanism driven by the first linear module to perform lifting movement. The nut feeding device is connected to the heating module through a feeding pipe. A guiding pipe is installed vertically on the heating module. The side pushing mechanism is used to push the nut heated in the heating module into the guiding pipe. The pressing mechanism is arranged above the heating module and is used to push the nut out of the guiding pipe and press it into the product. This automatic hot melt nut implanting device can automatically heat and press the nut into the product, saving manpower, improving efficiency and ensuring product quality.

[0005] In order to overcome the above deficiencies, the Chinese patent of the prior art (application number 202323446937.5) discloses an injection molding hot melt nut device, a first linear module and a second linear module arranged relatively parallel. A first carrier plate that moves horizontally is arranged on the first linear module. A hot melt machine that moves horizontally is arranged on the second linear module. A printing machine corresponding to the first carrier plate is arranged at the end of the first linear module. A second carrier plate corresponding to the hot melt machine is arranged at the end of the second linear module. Injection molded parts are positioned and supported inside the first carrier plate and the second carrier plate. A manipulator is arranged between the first linear module and the second linear module. A clamping part for clamping nuts and an adsorption module for adsorbing and positioning injection molded parts are arranged at the driving end of the manipulator in a lifting connection manner, achieving an improvement in the processing efficiency.

[0006] Although the prior art can overcome the above-mentioned deficiencies, there are still other problems in its operation. For example, when pressing the heated nut into the reserved hole of the injection molded part, the nut needs to be pre-heated in advance, which takes a relatively long time. Subsequently, pressing the nut into the injection molded part is slower, which easily leads to a long processing time and a slow hot melting rate. Summary of the Invention

[0009] Furthermore, the base and the placement platform are connected by an electric slide rail and an electric slider, and the vertical plate and the lifting plate are connected by an electric slide rail and an electric slider.

[0010] Furthermore, the auxiliary positioning mechanism further includes a knob, and the inner side of the knob is fixedly installed on the outer side of the bidirectional threaded rod, and the threads at the left and right ends of the bidirectional threaded rod are opposite.

[0011] Furthermore, a limiting rod is installed through the lower end of the clamping plate, and the left and right ends of the limiting rod are fixedly installed on the inner wall of the placement platform. The shape of the clamping plate is "T" shaped, and an anti-slip pad is fixedly installed on the inner side of the upper end of the clamping plate.

[0012] Furthermore, the rotating pressing mechanism further includes a sliding plate, and the front end of the sliding plate is fixedly installed at the rear end of the lifting plate, and the sliding plate is slidably connected inside the vertical plate.

[0013] Further, a gear rod is rotatably installed on the surface of the skateboard, and the rear end of the gear rod is meshed and installed with a toothed plate. A rotating rod is rotatably installed on the surface of the lifting plate, and the left and right sides of the rotating rod are sleeved with the gear rod through pulleys and transmission belts.

[0014] Further, a first bevel gear is fixedly installed at the middle end of the rotating rod, and a second bevel gear is meshed and installed at the lower end of the first bevel gear. The lower end of the second bevel gear is fixedly installed at the upper end of the driving rod, and a first gear is fixedly installed at the lower end of the driving rod. A second gear is meshed and installed at the front end of the first gear, and the second gear is arranged on the surface of the pressing rod head.

[0015] Further, the auxiliary pressing mechanism further includes a first inclined block, and the left side of the first inclined block penetrates through and is installed inside the fixed bin. A return spring is sleeved on the surface of the first inclined block, and the left and right sides of the return spring are arranged on the inner wall of the fixed bin and the inner side of the first inclined block.

[0016] Further, a positioning plate is fixedly installed on the surface of the lifting plate, and a knocking block is slidably connected to the inner side of the positioning plate. A second inclined block is fixedly installed at the front end of the knocking block, and a vibration spring is arranged between the positioning plate and the knocking block. A moving block is fixedly installed on the outer side of the first inclined block, and the moving block corresponds to the second inclined block.

[0017] Further, a vibration plate is arranged at the front end of the vertical plate, and the shape of the vibration plate is "L"-shaped. Convex blocks are uniformly fixedly installed on the bottom surface of the vibration plate, and the upper ends of the convex blocks are located below the placing platform. The rear end of the knocking block corresponds to the vibration plate through a round rod.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. When processing along with the lifting plate moving along the electric slide rail through the electric slider, the gear rod rotatably installed on the upper end of the skateboard meshes and moves along the toothed plate. With the rotation of the gear rod, under the action of the pulley and the transmission belt, the rotating rod can be driven to rotate. When the rotating rod rotates, the second gear can be driven by the first gear. The rotation of the second gear causes the pressing rod head to press down and rotate at the same time, so that when the nut is hot-melt embedded, it can rotate and be integrated into the injection molded part at the same time, thereby improving the processing efficiency of the hot-melt nut device and improving the efficiency of the user.

[0020] 2. When processing injection molded parts, place the injection molded parts on the placement platform on the base. At this time, rotate the knob. The rotation of the knob can drive the threaded rod to rotate. When the threaded rod rotates, it can drive the clamping plate that is threadedly connected to it. Under the limitation of the limiting rod, the clamping plate can make the clamping plate clamp the injection molded parts on the surface of the placement platform as the threaded rod rotates. And with the setting of the anti-slip pad, it can prevent the injection molded parts from shifting;

[0021] Furthermore, with the setting of the left and right two groups of processing parts, they can be operated alternately, which is convenient for the staff to stably pre-embed the hot-melt nuts in the injection molded parts. The operation is simple and convenient, and it can be operated alternately left and right, with high processing efficiency and accurate precision positioning.

[0022] 3. When the drive belt drives the rotating rod to rotate through the pulley, the fixed lever on the surface of the drive belt moves as the drive belt moves. At this time, as the fixed lever moves, it can push the first inclined block to move. When the first inclined block is squeezed, the vibrating plate is struck to generate vibration, and the vibrating force is transmitted to the convex block. The convex block strikes the bottom of the placement platform to assist the nut to be embedded into the injection molded part, further improving the efficiency during the processing of the hot-melt nut and enabling the nut pre-embedding of the injection molded part to be carried out more quickly.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Embodiment 1: As Figures 1 - 5 shown in the technical solution, a high-precision and automated hot-melt nut device, in order to solve the problem that the injection molded parts are prone to offset during the hot-melt nut processing of injection molded parts, discloses: a base 1 and a placing platform 2 provided at the upper end of the base 1, and a vertical plate 3 is installed on the surface of the base 1, and a lifting plate 4 is provided at the front end of the vertical plate 3, and a heater 5 is installed at the lower end of the lifting plate 4, and a sleeve part 6 is installed at the lower end of the heater 5, and a pressing rod head 7 is provided at the lower end of the sleeve part 6; a bidirectional threaded rod 8 is provided inside the placing platform 2, and an auxiliary positioning mechanism is installed on the surface of the bidirectional threaded rod 8, and the auxiliary positioning mechanism includes a clamping plate 9, and the middle end of the clamping plate 9 is threadedly connected to the bidirectional threaded rod 8. The base 1 and the placing platform 2 are connected by an electric slide rail and an electric slider, and the vertical plate 3 and the lifting plate 4 are connected by an electric slide rail and an electric slider.

[0036] When processing injection molded parts, place the injection molded parts on the placement platform 2 on the base 1. At this time, rotate the knob 12. The rotation of the knob 12 can drive the threaded rod to rotate. When the bidirectional threaded rod 8 rotates, it can drive the clamping plate 9 threadedly connected to it. Under the limitation of the limiting rod 11, the clamping plate 9 can drive the clamping plate 9 to clamp the injection molded parts on the surface of the placement platform 2 as the bidirectional threaded rod 8 rotates. With the setting of the anti-slip pad 10, it can prevent the injection molded parts from shifting. At this time, place the nut in the hole reserved on the surface of the injection molded parts in advance. Then start the device. When performing the hot-melt nut operation, the lifting plate 4 can be adjusted up and down along the vertical plate 3 under the action of the electric slide rail and the electric slider. At the same time, the placement platform 2 can freely adjust the position of the injection molded parts with the setting of the two groups of electric slide rails and electric sliders at the lower end. The heater 5 heats the pressing rod head 7 at the bottom of the sleeve part 6. The heated pressing rod head 7 is aligned with the nut on the injection molded parts for heating and pressing.

[0037] Embodiment 2: As Figures 1 - 8 shown in this technical solution, on the basis of Embodiment 1, in order to solve the problem of low efficiency when the hot-melt nut is pressed down, it is disclosed that: a toothed plate 13 is provided at the rear end of the vertical plate 3, and a rotating pressing mechanism is installed at the front end of the toothed plate 13. The rotating pressing mechanism includes a driving rod 20, and the surface of the driving rod 20 is rotatably installed with the lifting plate 4.

The lower end of the driving rod 20 is fixedly installed with a first gear 21, and a second gear 22 is meshed and installed at the front end of the first gear 21, and the second gear 22 is arranged on the surface of the pressing rod head 7.

[0038] When processing with the lifting plate 4 moving along the electric slide rail through the electric slider, the gear rod 15 rotatably installed at the upper end of the slide plate 14 meshes and moves along the toothed plate 13. With the rotation of the gear rod 15, under the action of the pulley and the transmission belt 16, the rotating rod 17 can be driven to rotate. When the rotating rod 17 rotates, it can drive the second bevel gear 19 to rotate through the first bevel gear 18. The rotation of the second bevel gear 19 can drive the driving rod 20 to rotate. When the driving rod 20 rotates, it can drive the second gear 22 through the first gear 21. The rotation of the second gear 22 causes the pressing rod head 7 to press down and rotate at the same time, so that when the nut is hot-melt embedded, it can rotate and melt into the interior of the injection molded part at the same time, thereby improving the processing efficiency of the hot-melt nut equipment and the use efficiency of the user.

[0039] Embodiment 3: As Figures 1 - 10 shown in the technical solution, on the basis of Embodiment 2, in order to solve the problem of low efficiency, it is disclosed that: a fixed bin 24 is arranged on the surface of the lifting plate 4, and an auxiliary pressing mechanism is arranged inside the fixed bin 24. The auxiliary pressing mechanism includes a fixed dial rod 23, and the lower ends of the fixed dial rod 23 are evenly installed on the surface of the transmission belt 16.

The rear end of the knocking block 29 corresponds to the vibration plate 32 through a round rod.

[0040] When the drive belt 16 drives the rotating rod 17 to rotate through the pulley, the fixed lever 23 on the surface of the drive belt 16 moves along with the movement of the drive belt 16. At this time, with the movement of the fixed lever 23, the first inclined block 25 can be toggled to move. When the first inclined block 25 is squeezed, the first inclined block 25 moves outward to squeeze the return spring 26, and at the same time, the moving block 27 moves outward to squeeze the second inclined block 30. The second inclined block 30 is squeezed to push the knocking block 29, and the knocking block 29 is squeezed to slide along the inner side of the positioning plate 28 to squeeze the vibration spring 31. At this time, the knocking block 29 aligns with the vibration plate 32 for knocking, and the vibration plate 32 is knocked to generate vibration. The vibration force is transmitted to the convex block 33, and the convex block 33 aligns with the bottom of the placement platform 2 for knocking, so as to assist the nut to be embedded into the injection molded part, further improving the efficiency during the processing of the hot melt nut and enabling the nut pre-embedding of the injection molded part to be carried out more quickly.
