Description

Technical Field

[0001] This application relates to the field of nameplate processing technology, and in particular to a precision four-column hot melt machine for nameplate processing. Background Technology

[0002] In the hot-melt process of nameplate processing, thermoplastic polymer materials are usually heated to a molten state, and pressure is used to make the material and the substrate bond at the molecular level. After cooling and shaping, a permanent mark is formed.

[0003] In related technologies, the precision of nameplate processing directly determines the durability and appearance accuracy of the nameplate markings. Traditional nameplate processing methods usually involve workers manually heat-melting the zinc alloy and plastic parts together.

[0004] However, the existing processing methods have the following problems: manual single-piece operation is time-consuming and cannot achieve continuous, large-scale production. Therefore, a precision four-column hot melt machine for nameplate processing is needed to solve the above problems. Summary of the Invention

[0005] To improve the efficiency of nameplate processing, this application provides a precision four-column hot melt machine for nameplate processing.

[0006] The precision four-column hot melt machine for nameplate processing provided in this application adopts the following technical solution:

[0007] A precision four-column hot melt machine for nameplate processing includes a riveting mechanism, a hot melt frame, a feeding mechanism, a bearing mechanism, and a processing platform. The riveting mechanism includes a cylinder, a heat-conducting copper plate, a heat insulation plate, and a heating head. The piston rod of the cylinder is connected to the heat-conducting copper plate, and the heat-conducting copper plate and the heating head are connected through the heat insulation plate. The feeding mechanism includes an external robotic arm and several nameplate processing molds. The external robotic arm cooperates with the nameplate processing molds to realize bidirectional loading and unloading of nameplates.

[0008] By adopting the above scheme, the external robotic arm places the nameplate processing mold with the nameplate attached into the carrying mechanism. The cylinder is activated, driving the heating head to move downwards along with the piston rod of the cylinder until the heating head contacts the nameplate and performs riveting welding on the nameplate. After the riveting welding is completed, the piston rod of the cylinder resets, driving the heating head to reset as well. The external robotic arm then sends the nameplate processing mold carrying the completed riveted nameplate to the next process. The above process is repeated cyclically. Through the coordinated work between the hot melt frame, riveting mechanism, feeding mechanism, carrying mechanism, and controller, the fully automated continuous operation of the nameplate riveting welding process is realized, improving the processing efficiency of the nameplate.

[0009] Preferably, the hot melt machine frame includes a base, four support columns, an electrical box, and a mounting plate. The four support columns are fixed vertically to the base and the electrical box, respectively. The mounting plate is movably sleeved on the support columns in the vertical direction. The upper surface of the mounting plate is fixed to the piston rod of the cylinder. A heat-conducting copper plate is fixed on the mounting plate. The cylinder is installed inside the electrical box.

[0010] By adopting the above solution, the heat-conducting copper plate, heating head, and heat insulation plate are integrated on the mounting plate, combining the riveting and heating functions together.

[0011] Preferably, the mounting plate is provided with four guide sleeves, which are movably fitted onto the support columns, and the mounting plate slides along the length of the four support columns through the guide sleeves.

[0012] By adopting the above solution, the force is ensured to be uniform when the mounting plate and the support column cooperate with each other, which indirectly enhances the stability of the hot melt machine during operation.

[0013] Preferably, an external robotic arm is mounted on a processing platform, and several nameplate processing molds are neatly and orderly stacked on the processing platform.

[0014] The above solution optimizes the footprint of the hot melt machine and saves on start-up costs.

[0015] Preferably, the electrical box has a built-in controller, and the cylinder and the external robotic arm are all electrically connected to the controller.

[0016] By adopting the above scheme, the controller can synchronously control the cylinder and the external robotic arm. By coordinating the movement trajectory of the external robotic arm and the working cycle of the riveting and welding mechanism, the mechanical losses caused by structural interference between the mechanisms are effectively reduced.

[0017] Preferably, the bearing mechanism includes a bearing platform, and the upper surface of the bearing platform is provided with a bearing groove, the shape of which is adapted to several nameplate processing molds.

[0018] The above solution enables the bearing groove to play a major positioning role in the nameplate processing, thereby improving the riveting and welding accuracy.

[0019] Preferably, the bearing mechanism further includes a pressure sensor, which is embedded in the geometric center inside the bearing groove and is electrically connected to the controller.

[0020] Through the above scheme, the pressure sensor can detect the pressure generated by the nameplate processing mold and transmit the pressure signal to the controller to detect whether the nameplate processing mold has been correctly placed on the bearing platform, and can also monitor the pressure parameters subjected to the nameplate during processing in real time.

[0021] Preferably, the top of the base has several threaded holes, and the detachable limiting sheet metal is threadedly connected to any one of the threaded holes. The detachable limiting sheet metal is used to press the bearing platform.

[0022] By adopting the above solution, the detachable limiting sheet can play an auxiliary positioning role for the bearing platform, improving the riveting and welding accuracy. Furthermore, since the detachable limiting sheet can be installed at different positions on the machine base, it can be changed according to other mold shapes and riveting and welding requirements, making it more flexible.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Improved nameplate processing efficiency, enabling automated, large-scale continuous production;

[0025] 2. The efficient and sophisticated riveting and welding method improves the durability and aesthetics of the nameplate after processing, and also ensures a high yield rate;

[0026] 3. Reduced the risk of injury to workers in high-temperature working environments. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0031] This application discloses a precision four-column hot melt machine for nameplate processing. (Refer to...) Figure 1 It includes a riveting and welding mechanism 1, a hot melt frame 2, a feeding mechanism 3, a bearing mechanism 4, and a processing platform 5. The feeding mechanism 3 transports the nameplate to be processed to the bearing mechanism 4 directly below the hot melt frame 2. The riveting and welding mechanism 1 directly above the hot melt frame 2 applies pressure to melt the nameplate. After the nameplate is riveted and welded and cooled, the feeding mechanism 3 sends it to the next process.

[0032] Specifically, the hot melt frame 2 includes a base 21, four support columns 22, an electrical box 23, and a mounting plate 24. The four support columns 22 are arranged in a rectangular array and are fixed perpendicularly to the base 21 and the electrical box 23, respectively, providing sufficient mechanical structural strength for the hot melt frame 2. At the same time, the four-column support assembly is symmetrically arranged, and the mounting plate 24 undergoes more vertical displacement after thermal expansion, reducing lateral offset and enabling it to have thermal deformation compensation capability.

[0033] Furthermore, four guide sleeves 241 are provided on the mounting plate 24. The mounting plate 24 is movably sleeved on the four support columns 22 in the vertical direction. During movement, the frictional cooperation between the guide sleeves 241 and the support columns 22 reduces the trajectory deviation of the vertical movement of the mounting plate 24, improves the movement accuracy and stability of the equipment, and meets the stringent requirements of the precision hot melt process for displacement repeatability positioning accuracy of ±0.05mm.

[0034] On the other hand, the riveting and welding mechanism 1 includes a cylinder 11, a heat-conducting copper plate 12, a heat insulation plate 13, and a heating head 14. The cylinder 11 is installed inside the electrical box 23. The piston rod of the cylinder 11 extends vertically downward through the lower surface of the electrical box 23 and is fixed vertically to the mounting plate 24.

[0035] Furthermore, the top of the heat-conducting copper plate 12 is fixed to the lower surface of the mounting plate 24, the lower surface of the heat-conducting copper plate 12 is fixed to the heat insulation plate 13, and the lower surface of the heat insulation plate 13 is fixed to the heating head 14. The mechanical structure stability is enhanced, and because each component can be disassembled and replaced individually, the maintenance cost is reduced.

[0036] Furthermore, in this embodiment, the thermal conductivity of the heat-conducting copper plate 12 is 400 W / m·K, which is used to evenly diffuse the heat from the heating head 14. In this embodiment, the heat insulation plate 13 is made of ceramic fiber with a thermal conductivity of 0.13×10⁻²~2.00 W / m·K, which can effectively block the reverse heat transfer to protect the cylinder 11 and the built-in controller of the electrical box 23 and prevent the thermal failure of the controller circuit components in the electrical box 23.

[0037] Furthermore, the heat insulation plate 13, as a physical isolation layer, meets the requirements of the mechanical safety standard EN ISO 13857 for the protection distance of high-temperature components, preventing the risk of burns caused by heat conduction to metal components such as the frame support column 22, reducing heat loss, and controlling the temperature fluctuation of the heating head 14 within ±2℃, ensuring the consistency of the process parameters of heat melting pressure-temperature-time.

[0038] On the other hand, the feeding mechanism 3 includes an external robotic arm 31 and several nameplate processing molds 32. The external robotic arm 31 is fixedly connected to the upper surface of the processing platform 5. Several nameplate processing molds 32 are stacked on the upper surface of the processing platform 5. The external robotic arm 31 can grab several nameplate processing molds 32 and realize the transfer of several nameplate processing molds 32 between the processing area, the feeding area and the unloading area.

[0039] Therefore, the external robotic arm 31 and several nameplate processing molds 32 are centrally installed and placed in the designated working area of ​​the processing platform 5, which realizes the miniaturization of the equipment, improves the space utilization of the hot melt machine, and the parallel operation of multiple workstations also saves site rental costs and concentrates to increase production capacity.

[0040] Furthermore, the electrical box 23 has a built-in controller (not shown in the figure). The controller is electrically connected to the cylinder 11 and the external robotic arm 31. The controller can synchronously drive the cylinder 11 and control the external robotic arm 31. The electrical signal has low transmission delay characteristics, has a faster response time compared to the mechanical signal, and is not easily affected by the processing environment. By coordinating the movement trajectory of the external robotic arm 31 and the working cycle of the riveting and welding mechanism 1, the controller can reduce the mechanical losses caused by structural interference between the mechanisms.

[0041] Reference Figure 2 On the other hand, the bearing mechanism 4 includes a bearing platform 41, and a bearing groove 411 is provided on the upper surface of the bearing platform 41. The shape of the bearing groove 411 is adapted to the nameplate processing mold 32, which is used to actively position the nameplate processing mold 32, reduce the lateral displacement of the nameplate caused by the downward pressure during the riveting process, and improve the geometric accuracy of the riveting.

[0042] Furthermore, the bearing mechanism 4 also includes a pressure sensor 42, which is electrically connected to the controller. The pressure sensor 42 is non-contact and is embedded in the geometric center inside the bearing groove 411, which reduces direct contact with the high-temperature and high-frequency working environment of the hot melt machine, has better environmental adaptability and compatibility, and extends the service life of the pressure sensor 42.

[0043] Furthermore, when the external robotic arm 31 places the nameplate processing mold 32, which carries the nameplate to be processed, onto the support groove 411, the nameplate processing mold 32 exerts a certain pressure on the support platform 41. After the pressure sensor 42 detects the pressure, it transmits the pressure signal data to the controller. The controller analyzes and processes the pressure signal data, thereby driving the cylinder 11 to work. This not only detects whether the nameplate processing mold 32 has been correctly placed on the support platform 41, but also monitors the pressure data in real time during the nameplate processing process by the heating head 14, and dynamically adjusts the working command of the cylinder 11, thereby reducing mechanical errors and helping to improve the yield rate.

[0044] Furthermore, the top of the base 21 has several threaded holes. The detachable limiting sheet metal 43 is threadedly connected to any of the threaded holes. The lower surface of the detachable limiting sheet metal 43 abuts against the upper surface of the bearing platform 41. By pressing the bearing platform 41, the detachable limiting sheet metal 43 plays an auxiliary positioning role for the bearing platform 41, which indirectly improves the riveting and welding accuracy. Since the detachable limiting sheet metal 43 can be installed in different positions on the base 21, it can be designed with multiple hole positions to adapt to other mold shapes and riveting and welding requirements, so as to realize dynamic limiting adjustment.

[0045] The implementation principle of a precision four-column hot melt machine for nameplate processing according to an embodiment of this application is as follows: The external robotic arm 31 accurately places the nameplate processing mold 32 containing the nameplate into the bearing groove 411 on the bearing platform 41. After the pressure sensor 42 detects the pressure, it sends an electrical control command to the controller. The controller drives the cylinder 11 to move linearly, causing the mounting plate 24 to move vertically along the four support columns 22. The heat-conducting copper plate 12 and the heating pressure head 14 fixed with the mounting plate 24 move down synchronously to the predetermined station, so that the riveting working surface and the nameplate surface form a contact pressure coupling. After maintaining the predetermined pressure parameters and continuously heating to the set time threshold, the cylinder 11 drives the riveting mechanism 1 to perform a reverse stroke reset. After the pressure sensor 42 confirms that the reset is completed, the external robotic arm 31 transfers the nameplate processing mold 32, which has been loaded with riveted parts, to the next process tooling. Subsequently, the control system executes the above process in a cycle according to the preset program. Through the coordinated work between the hot melt frame 2, the riveting mechanism 1, the feeding mechanism 3, the carrying mechanism 4, and the controller, the fully automated continuous operation of the nameplate riveting process is realized, which improves the processing efficiency of the nameplate.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
