[0002] In industrial applications, hot-melt copper nut processing is a common nut processing solution. The copper nut and plastic parts are heated by hot-melt equipment. During the heating process, the plastic parts are gradually softened and the copper nut is firmly embedded in the plastic parts, thereby realizing the preparation of hot-melt copper nut samples.

[0003] When processing hot-melt copper nuts, it is necessary to accurately locate the position of the copper nut and the plastic component to ensure that the copper nut falls into the designated area of the plastic component. Once a position deviation occurs, the processed product will not meet the standards. In actual application, the sizes and specifications of copper nuts vary, and existing hot-melt copper nut processing equipment can generally only continuously produce products of a single specification. When preparing hot-melt copper nut screw column products of different sizes, it is necessary to change the relevant parameters of the processing equipment and repeatedly perform positioning.

[0037] This application provides a copper nut processing device, which realizes the replacement of different boss specifications through the detachable design of the hot melt head, thereby adapting to copper nuts of different specifications. The module diagram of the copper nut processing device is shown in the attached figure. Figure 1 The specific plan is as follows:

[0038] A hot-melt copper nut processing device with a positioning function is used to install copper nuts on plastic parts. The copper nut processing device includes a main body 1, a positioning fixture 2 and a hot melt head 3. The main body 1 is the main structure of the copper nut processing device, including a workbench 12, a moving mechanism 11, a guide structure, a heating structure and other structural parts except the hot melt head 3. Among them, the workbench 12 is mainly used to carry the positioning fixture 2. The moving mechanism 11 is connected to the hot melt head 3, and the hot melt head 3 is responsible for adsorbing and fixing the copper nut. Driven by the moving mechanism 11, 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 in the plastic part to complete the fixation.

[0039] The moving mechanism 11 includes but is not limited to any known solution capable of moving an object, such as pneumatic drive, robotic arm drive, etc. Exemplarily, the moving mechanism 11 includes a drive motor, a moving part, and a bracket, wherein the moving part is located on the bracket, and the drive part is used to drive the moving part to move up and down along the bracket. Exemplarily, the moving mechanism 11 is a lifting structure, including an air pump, an air cylinder, and a moving rod, wherein the moving rod is located in the inner cavity of the air cylinder and can move in the inner cavity, and a welding head 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, thereby driving the hot melt head 3 to move.

[0040] Instructions attached Figure 2 The structural example of the positioning fixture 2 is given in FIG. The positioning fixture 2 includes at least a fixture base 22 and a fixing structure 21. Figure 2In the embodiment, the fixing structure 21 is specifically presented as a protruding structure relative to the fixture base 22. The fixing structure 21 is fixedly connected to the fixture base 22; the fixture base 22 is provided with a connecting structure 23 for detachable connection with the workbench 12. The connection relationship between the positioning fixture 2 and the workbench 12 is shown in the attached figure. Figure 3 As shown in the figure, the jig base 22 is the main body 1 structure of the positioning jig 2 and serves as the supporting body 1 for other jig structures. The fixing structure 21, connecting structure 23, positioning structure 24, and similar structures are all integrated into the jig base 22. In addition, some markings, such as the parameters of the corresponding copper nuts or plastic components, can also be marked on the jig base 22 to facilitate the operator to access relevant dimensional specifications. The workbench 12 is a structure on the main body 1 specifically for connecting to the jig base 22.

[0041] In the present application, the positioning jig 2 is equivalent to an intermediate structure, which realizes the position limitation among the copper nut, the main body 1 and the plastic component. The positioning jig is fixed to the main body 1, and the plastic component must be fixed to the positioning jig 2 in a specific posture, thereby realizing that the plastic component is fixed to the main body 1 in the correct posture. In some specific embodiments, the positioning jig 2 is located below the hot melt head 3, and the positioning jig 2 is used to align the plastic component with the copper nut above. When the positioning jig 2 is located directly below the hot melt head 3, it is only necessary to control the moving mechanism 11 to move the copper nut up and down to move closer to or away from the plastic component, without the need to adjust the posture of the copper nut in other directions. In the field of automatic production operations, the accurate connection between processes will directly affect the production process and production efficiency. Setting the positioning structure 24 below the hot melt head 3 so that the copper nut is facing the installation area on the plastic component below can greatly reduce the complexity of the moving mechanism 11, improve processing efficiency, and reduce processing costs.

[0042] In some embodiments, the fixture base 22 is in a flat columnar shape, as shown in the attached Figure 2-5 As shown. The material of the jig base 22 can be stainless steel or other materials, which can not only reduce the impact of temperature on the processing jig, but also have a certain durability and can be used for a long time. At the same time, it is easy to process and has low cost. In actual applications, the positioning jig 2 needs to be fixed to a specific platform, and the platform needs to be provided with a relevant bearing structure that can match the positioning jig 2. For example, a placement table 13 and a workbench 12 are provided on the main body 1. The placement table 13 is used to carry positioning jigs 2 and hot melt heads 3 of different specifications and sizes, while the workbench 12 is responsible for carrying the positioning jig 2 that is about to perform the processing task. In actual applications, a positioning jig 2 and a hot melt head 3 of appropriate specifications are selected on the placement table 13, and the positioning jig 2 is fixed on the workbench 12, and the hot melt head 3 is installed on the moving mechanism 11. After the processing is completed, the positioning jig 2 is removed and placed back on the placement table 13.

[0043] In some specific embodiments, the positioning jig 2 is further provided with a positioning structure 24, which is located on the jig base 22 and is used alone or in conjunction with the connecting structure 23 to achieve limiting the position of the jig base relative to the main body 1. The positioning structure 24 is used to fix the positional relationship between the positioning jig 2 and the main body 1. The positioning jig 2 is usually installed on the workbench 12 of the main body 1. To ensure that the positioning jig 2 is located below the hot melt head 3 and can be fixed after installation, a positioning structure 24, a connecting structure 23, etc. are required to achieve this. Among them, the connecting structure 23 is indispensable, and the connecting structure 23 can also achieve the positioning function to a certain extent. For example, the connecting structure 23 includes at least two holes, and the workbench 12 is provided with corresponding threaded holes at the corresponding positions of the holes. The bolts pass through the holes and are connected to the threaded holes, which can fix the positioning jig 2 to the workbench 12. When there are more than two holes, the connecting structure 23 can constitute the positioning structure 24 to achieve the positioning function. In some specific embodiments, n fixing columns are provided on the workbench 12, and the connecting structure 23 includes n connecting holes that match the positions and sizes of the fixing columns. The fixing columns can be embedded in the connecting holes, and n is a positive integer not less than 2. For example, two fixing columns are raised on the workbench 12, and the sizes of the fixing columns match the connecting holes. When the fixture base 22 is installed on the workbench 12, the outer walls of the fixing columns are close to the inner walls of the connecting holes. Together with the connecting structure 23, the fixing + positioning functions can be achieved. In the present application, the fixing + positioning functions can be achieved by the connecting structure 23 alone, or the fixing function can be achieved by the connecting structure 23 and the positioning function can be achieved by the positioning structure 24. Or the fixing function can be achieved by the connecting structure 23 and the positioning function can be achieved by the connecting structure 23 + the positioning structure 24. In actual applications, a suitable fixing + positioning solution can be selected according to production needs.

[0044] In some specific embodiments, a positioning hole and a nut hole are provided on the plastic component. The nut hole is used to install the copper nut, and the positioning hole is aligned with the nut hole; part or all of the fixing structure 21 can be detachably connected to the positioning hole. For example, the plastic component is a plastic screw column, one end of which is used to install the copper nut, and the other end can be snap-fitted to the fixing structure 21. Figure 4 and 5 In the embodiment, the fixing structure 21 is a boss that protrudes relative to the fixture base 22, and one end of the plastic component is a positioning hole that can be snap-fitted to the boss. In this application, a stable connection between the plastic component and the fixing structure 21 is required to prevent the plastic component from shaking left and right on the positioning fixture 2, thereby affecting the installation of the copper nut. Therefore, the size relationship between the inner diameter of the positioning hole and the outer diameter of the boss can be defined, so that the inner diameter of the positioning hole is slightly larger than the outer diameter of the boss, so that the inner wall of the positioning hole is tightly attached to the outer wall of the boss after installation, thereby preventing the plastic component from shaking on the positioning fixture 2.

[0045] In some specific embodiments, the fixing structure 21 is a frustum-like structure as a whole or the end away from the fixture base 22 is a frustum-like structure. The end of the fixing structure 21 is reduced to facilitate the fixing structure 21 to extend into the plastic component to complete the installation. Taking the fixing structure 21 as a boss as an example, the boss can be a frustum-like structure as a whole, as shown in the attached figure. Figure 4 As shown, it can also be a combination of cylinder + frustum, as shown in the attached Figure 5 As shown. Exemplarily, the fixed structure 21 is a truncated cone-like structure with two bottom surfaces; one bottom surface is fixedly connected to the fixture base 22 and has an area larger than the other bottom surface. Exemplarily, the fixed structure 21 is a combination of a truncated cone-like structure and a truncated cone-like structure, with the truncated cone-like structure connected to the fixture base 22 and the truncated cone-like structure, respectively, and the end of the fixed structure 21 is the smaller bottom surface of the truncated cone-like structure.

[0046] In some specific embodiments, a marking area is provided on the positioning jig 2, and the marking area is used to mark the size specifications of the copper nut adapted to the hot melt head 3. In this application, the fixing structure 21 matches the structure of the plastic component, and each specification of the plastic component corresponds to a specification of the copper nut. Therefore, each positioning jig 2 corresponds to a specification of the copper nut. The specification model of the corresponding copper nut can be marked on the positioning jig 2 to facilitate the selection of the appropriate positioning jig 2. Figure 6 In the diagram, area A is the marking area, and M3.0 in the marking area indicates the model of the copper nut.

[0047] In some specific embodiments, the fixing structure 21 is located in the central area of the fixture base 22, and the positioning structure 24 and the connecting structure 23 are offset from the central area. Figure 2 As shown, the central location of the fixing structure 21 and the eccentric placement of the positioning structure 24 and the connecting structure 23 not only rationally arrange the positions of the various components on the fixture base 22, but also enhance the stability of the connection of the connecting structure 23. Furthermore, placing the fixing structure 21 in the central area of the fixture base 22 also facilitates the installation of plastic components and determines the positional relationship between the plastic components and the hot melt head 3.

[0048] In some specific embodiments, the connecting structure 23 is a threaded hole, and a connecting hole that matches the position and size of the threaded hole is opened on the workbench 12, and the inner wall of the connecting hole is provided with a thread that matches the threaded hole; the workbench 12 is used to achieve a detachable connection with the positioning fixture 2 through the cooperation of external bolts and threads.

[0049] In this application, the hot melt head 3 needs to absorb the copper nut and gradually embed the copper nut into the plastic component under heating conditions under the drive of the moving mechanism 11. The hot melt head 3 itself must have certain temperature characteristics and be able to absorb the copper nut.

[0050] In some specific embodiments, the hot melt head 3 includes a connector, a base, and a platform. The connector is located at one end of the base, and the platform is located at the other end. The platform matches the specifications of the copper nut and is used to attract and secure the copper nut. The hot melt head 3 is detachably connected to the telescopic structure via the connector, which is used to move the copper nut toward or away from the plastic component. The connector and platform are located on either side of the base, and the cross-sectional area of the platform depends on the specifications of the copper nut. When the inner diameter of the copper nut is large, the cross-sectional area of the platform should also be large to ensure that the copper nut can be attracted and secured to the platform.

[0051] In the present application, the hot melt head 3 needs to be easy to fix and release to facilitate the automatic installation of the copper nut. The hot melt head 3 can adopt air pressure adsorption, mechanical support and other methods to ensure the relative fixation between the hot melt head 3 and the copper nut. Preferably, a pneumatic clamp or a blowing device is used to move and position the copper nut, and the position of the nut is controlled by airflow. In some specific embodiments, a pneumatic structure is also provided on the main body 1, and an air hole connected to the air pressure structure is provided on the table; the air pressure structure is used to extract the air pressure in the air hole to adsorb and fix the copper nut. Since the mass of the copper nut is relatively small, the copper nut can be firmly fixed to the hot melt head 3 by air pressure adsorption. The copper nut can be fixed and released by simply adjusting the air pressure of the air pressure structure. The operation is simple, the adsorption is stable and the cost of use is low.

[0052] This utility model provides a hot-melt copper nut processing device with a positioning function. Using a detachable positioning fixture as a bridge, the copper nut and plastic component are positioned, ensuring alignment between the copper nut and the plastic component, reducing problems such as implant difficulty and high defect rates caused by inaccurate positioning. Furthermore, the positioning fixture can be adapted to plastic components and copper nuts of different specifications, enabling the production of hot-melt copper nuts of varying sizes.

[0053] The above is a specific description of the preferred implementation of the present invention, but the invention of the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
