[0037] The present application provides a hot-melt copper nut processing device. By the detachable design of the hot-melt head, the replacement of different boss specifications can be achieved, and thus copper nuts of different specifications can be adapted. The schematic diagram of the modules of the hot-melt copper nut processing device is shown in the appendix Figure 1 as shown, and the structure of the hot-melt head is as Figures 2 - 3 shown as follows:

[0038] A hot-melt copper nut processing device includes a device main body 1 and a hot-melt head 3. The device main body 1 is the main structure of the hot-melt copper nut processing device, including mechanism parts other than the hot-melt head 3 such as a moving mechanism 2, a workbench 4, a guiding mechanism, and a heating mechanism. A moving mechanism 2 for connecting the hot-melt head 3 is provided on the device main body 1. The hot-melt head 3 is responsible for adsorbing and fixing the copper nut. Driven by the moving mechanism 2, the hot-melt head 3 together with the copper nut is accurately positioned above the plastic part to be processed. Under heating conditions, the copper nut will be embedded into the plastic part to complete the fixation.

[0039] Among them, the moving mechanism 2 includes but is not limited to any known solution capable of realizing the movement of an object, such as pneumatic drive, robotic arm control, etc. Exemplarily, the moving mechanism 2 includes a driving motor, a moving part, and a bracket. The moving part is located on the bracket, and the driving part is used to drive the moving part to move up and down along the bracket. Exemplarily, the moving mechanism 2 is a lifting mechanism, including an air pump, an air cylinder, and a moving rod. The moving rod is located in the inner cavity of the air cylinder and can move in the inner cavity. A melting joint is connected to the moving rod; by controlling the air pressure in the inner cavity of the air cylinder through the air pump, the movement of the moving rod can be controlled, and thus the movement of the hot-melt head 3 can be driven.

[0040] In the present application, the hot-melt head 3 includes a connecting piece 33, a base 31, and a boss 32. The connecting piece 33 is located at one end of the base 31, and the boss 32 is located at the other end of the base 31; the boss 32 matches the size specification of the copper nut and is used to adsorb and fix the copper nut; the hot-melt head 3 is detachably connected to the moving mechanism 2 through the connecting piece 33 and is used to move the copper nut closer to or farther away from the plastic part under the drive of the moving mechanism 2. In the structure of the hot-melt head 3 shown in the appendix Figure 2 the connecting piece 33 and the boss 32 are arranged on both sides of the base 31, and the cross-sectional area of the boss 32 depends on the specification of the copper nut. When the inner diameter of the copper nut is larger, the cross-sectional area of the boss 32 naturally also needs to increase to ensure that the outer side wall of the boss 23 is as close as possible to the inner side wall of the copper nut, and the copper nut is adsorbed and fixed on the boss 32. The present application improves the boss 32 part of the hot-melt head 3 to adapt to copper nuts of different specifications, and designs the hot-melt head 3 to be detachably connected. Since the processing cost of the hot-melt head 3 is relatively low, improving the hot-melt head 3 can minimize the processing cost as much as possible.

[0041] In the present application, the hot melt head 3 needs to be able to fix and release the fixing of the copper nut to facilitate the movement and installation of the copper nut. The hot melt head 3 can adopt methods such as pneumatic adsorption and mechanical clamping to ensure the relative fixation between the hot melt head 3 and the copper nut. For example, a special fixture is integrated on the hot melt head 3 to fix the copper nut by means of a mechanical structure. This method is simple and effective, but the fixture may need to be customized according to the size and shape of the nut, and has extremely high requirements for the positioning accuracy. Another example is that since copper nuts are generally made of non-magnetic materials, it is difficult to directly adsorb copper nuts by electromagnetic adsorption. Therefore, a magnetic component can be embedded in the copper nut or the copper nut can be attached to a magnetic object to make it magnetic, indirectly realizing the electromagnetic adsorption of the copper nut.

[0042] In some specific embodiments, an air pressure mechanism 5 is further provided on the device main body 1, and an air hole 34 communicating with the air pressure mechanism 5 is provided on the convex platform 32; the air pressure mechanism 5 is used to extract the air pressure in the air hole 34 to adsorb and fix the copper nut. Since the mass of the copper nut is relatively small, the copper nut can be firmly adsorbed on the convex platform 32 through a sufficient air pressure difference. In practical applications, the fixing and releasing of the copper nut are controlled by adjusting the air pressure of the air pressure mechanism 5, and at the same time, the adsorption strength can also be adjusted, with simple operation, firm adsorption and low use cost.

[0043] In some specific embodiments, an air passage 35 communicating with the air hole 34 is opened inside the base 31, and the air pressure mechanism 5 communicates with the air hole 34 through the air passage 35. This solution has certain requirements for the thickness of the base 31, which needs to be able to accommodate at least one air passage 35. There must be a channel connecting the air pressure mechanism 5 and the air hole 34. An air passage 35 communicating with the air hole 34 can be opened inside the base 31, and an air passage 35 can also be opened inside the connecting member 33. The two air passages 35 are connected, and the air pressure mechanism 5 communicates with the air passages 35 inside the connecting member 33 and the base 31 through a pipeline, so as to realize the connection between the air pressure mechanism 5 and the air hole 34. The layout of the air passage 35 inside the hot melt head 3 is as shown in the appendix Figure 4 shown. Or only an air passage 35 can be opened inside the base 31, and this air passage 35 directly communicates with the external pipeline and then communicates with the air pressure mechanism 5, without additionally opening an air passage 35 inside the connecting member 33. The layout of the air passage 35 inside the hot melt head 3 is as shown in the appendix Figure 5 shown. The external pipeline is directly connected to the base 31, without additional improvement to the connecting member 33 and the moving mechanism 2, and the maintenance is convenient, which is convenient for detecting the airtightness of the external pipeline, the air passage 35 and the air hole 34.

[0044] In some specific embodiments, the boss 32 includes a first body 321 and a second body 322. One end of the first body 321 is fixedly connected to the base 31, and the other end is fixedly connected to the second body 322. The contact area between the first body 321 and the base 31 is larger than the contact area between the first body 321 and the second body 322; the air hole 34 is located on the second body 322. The first body 321 and the second body 322 are specifically as shown in the appendix Figure 3 as shown. The first body 321 is equivalent to constructing a connecting part for the second body 322, which facilitates the fixed connection between the boss 32 and the base 31, and the second body 322 is the main structure of the boss 32. Exemplarily, the outer diameter of the first body 321 is larger than the outer diameter of the second body 322, and the outer diameter of the second body 322 matches the inner diameter of the copper nut. During use, the first body 321 can play a certain limiting role. The first body 321 is mainly to facilitate the relative fixation between the second body 322 and the base 31. For example, an installation hole is provided on the first body 321, and the size of the installation hole matches that of the second body 322. The second body 322 can be embedded into the installation hole to achieve the relative fixation between the boss 32 and the base 31. In some specific embodiments, the second body 322 can also be directly welded to the base 31 without setting the first body 321.

[0045] In some specific embodiments, the second body 322 is in a columnar shape and its outer diameter is smaller than the inner diameter of the copper nut; the second body 322 is used to extend into the area (i.e., the screw hole) formed by the inner side wall of the copper nut. The boss 32 needs to penetrate into the screw hole of the copper nut, and the screw hole is a cylindrical space formed by the inner side wall of the copper nut. To ensure the adsorption strength and adsorption stability, the boss 32 can also be designed as a cylindrical structure to facilitate the stable adsorption between the boss 32 and the copper nut.

[0046] In some specific embodiments, one or more air holes 34 are distributed on the side surface of the second body 322 to adsorb the inner side wall of the copper nut. The copper nut itself is relatively light, and the copper nut can be completely fixed only by a single air hole 34 on the side wall of the second body 322. To increase the adsorption force, the number and distribution position of the air holes 34 can be adjusted adaptively. Preferably, the size of the second body 322 is adapted to the inner diameter of the copper nut. The boss 32 uses the second body 322 to achieve the size matching with the copper nut. The second body 322 extends into the copper nut and has air holes 34 on its side wall. The closer the outer diameter of the second body 322 is to the inner diameter of the copper nut, the better the adsorption effect. Therefore, by setting the outer diameter of the second body 322 to match the inner diameter of the copper nut, the hot melt head 3 with different outer diameters of the second body 322 corresponds to different specifications of copper nuts. The specification size of the hot melt head 3 is only reflected in the size of the second body 322, further reducing the processing cost and processing difficulty.

[0047] In this application, the hot melt head 3 is detachably connected to the moving mechanism 2 by means of a connecting member 33, which facilitates direct replacement after determining the copper nut and the corresponding specification of the hot melt head 3. The connecting member 33 can be selected from any known detachable connection structure as needed, such as threaded connection, snap connection, etc. In some specific embodiments, the connecting member 33 includes a cylinder and threads distributed on the outer surface of the cylinder, and the cylinder is fixedly connected to the base 31; the connecting member 33 is threadedly connected to the moving mechanism 2. As shown in the attached Figure 2 figure, threads are distributed on the connecting member 33, and a threaded hole matching the threads is provided on the moving mechanism 2.

[0048] The shape of the base 31 can be set according to the actual application scenario. In some embodiments, threads are attached to the connecting member 33. To facilitate rotary connection using tools, at least two mutually parallel or nearly parallel planes can be provided on the side surface of the base 31, which facilitates installation using specific clamping tools such as wrenches. In the attached Figure 2 example figure, the side surface of the base 31 is a combination of a plane and a curved surface, which is equivalent to cutting off a part of the area from the bottom surface on a cylinder to form a plane. In some specific embodiments, a marking area is provided on the plane, and the marking area is used to display the model of the copper nut adapted to the boss 32. Printing is convenient in the plane area. In the attached Figure 2 and 3 , the area where M3.0 is located is the marking area, and M3.0 represents the model of the copper nut. In the melt joint shown in the attached Figure 2 , the side surface of the base 31 has two planes and they are opposite to each other. The models of the adapted copper nuts can be added to both planes, which is convenient for obtaining model information from different angles.

[0049] The present utility model provides a hot melt copper nut processing device. Through the detachable design of the hot melt head structure and the boss that can be adapted to specific specifications of copper nuts, the preparation of hot melt copper nut products with different size specifications is realized. The processing operation is simple, the installation of the hot melt head is convenient, and on the basis of controlling the processing cost, the processing efficiency and processing quality of multi-specification copper nut products are greatly improved.

[0050] The above is a specific description of the preferred embodiments of the present utility model, but the present utility model is not limited to the described embodiments. Those skilled in the art can also make various equivalent deformations or replacements without departing from the spirit of the present utility model, and these equivalent deformations or replacements are all included within the scope defined by the claims of this application.
