Description

Technical Field

[0001] This utility model relates to the field of hot riveting fixture technology, and in particular to a high-strength hot riveting fixture. Background Technology

[0002] A circuit board hot riveting fixture is a tool specifically used in the assembly of LED modules to fix the various components of the circuit board module together through a hot riveting process. Its working principle is to use heating elements (such as heating tubes or heating rods) to heat the rivets or rivets to a certain temperature to soften them, and then use pressure to press the softened rivets or rivets into the components to be riveted, so as to deform and fix them, thereby realizing the connection between the components.

[0003] An existing patent (publication number: CN217752820U) discloses "This utility model relates to a hot riveting fixture for LED modules, including a worktable, a gantry frame fixed to the top surface of the worktable, a fixing mechanism located inside the gantry frame on the worktable for fixing LED modules, a dual-axis linear module fixed to the inner top wall of the gantry frame, a lifting mechanism below the dual-axis linear module, a metal chamber with a bottom opening below the lifting mechanism that can be driven up and down by the lifting mechanism, a crossbar vertically fixed between the inner walls of the left and right sides of the metal chamber, a plurality of sliders that can slide left and right on the crossbar, and a riveting post fixed to the front of the slider. This hot riveting fixture for LED modules allows for adjustment and movement of two sets of riveting posts according to the distance between the riveting points of different products. Furthermore, when the distance between the two riveting points is relatively large, the distance between the two riveting posts can be manually adjusted, avoiding individual hot riveting operations on the riveting points. The operation is simple and convenient, improving work efficiency and hot riveting efficiency."

[0004] In the process of realizing this application, the inventors discovered the following problems with the prior art: the positions of each hot riveting head in the existing hot riveting fixture are relatively fixed, and the contact surface between the upper and lower fixtures is not protected. In actual use, the adjustable range of the device is small, and wear will occur after long-term use, affecting its processing accuracy.

[0005] Therefore, those skilled in the art have provided a high-strength hot riveting fixture to solve the problems mentioned in the background art. Utility Model Content

[0030] Reference Figure 3 , Figure 4 The upper fixture mechanism 3 includes a movable plate 301. Each of the four corners of the movable plate 301 has a first through hole 302. An upper fixed box 303 is fixedly installed in the middle of the bottom surface of the movable plate 301. Upper positioning plates 304 are fixedly installed on both sides of the bottom surface of the upper fixed box 303.

[0031] Specifically, by providing a movable plate 301 with a first through hole 302 on its surface, the movable plate 301 can slide along the surface of the guide rod 5 through the first through hole 302 during use, thereby adjusting the position of the upper fixture mechanism 3. By providing an upper fixed box 303 with an upper positioning plate 304 on its surface, the user can slide the upper fixture body 305 in the upper fixed box 303 to a suitable position during use. After adjustment, the upper fixture body 305 is secured by bolts through the first positioning hole 306 on the surface of the upper fixture body 305 and the hole on the surface of the upper positioning plate 304. The upper fixture body 305 is fixed, making the device adaptable to circuit boards of different shapes and thicknesses. The upper protective pad 307, which is supported by high-carbon steel and fixed to the surface of the upper fixture body 305 by bolts, can improve the strength of the contact surface between the upper fixture mechanism 3 and the lower fixture mechanism 4 and reduce wear during use. The hot riveting head 308, which is connected to a heating element and a control circuit, can realize the hot riveting function of the device during use.

The surface of the lower protective pad 401 is provided with a slot to fix the circuit board and prevent it from moving during processing. According to the shape and thickness of the circuit board, the position of the lower fixture body 403 in the lower fixing box 405 is adjusted by sliding to align it with the riveting point of the circuit board. At the same time, the position of the upper fixture body 305 in the upper fixing box 303 is adjusted by sliding to align it with the position of the lower fixture body 403. After adjustment, bolts are used to fix it through the second positioning hole 402 on the surface of the lower fixture body 403 and the hole on the surface of the lower positioning plate 404. Bolts are also used to fix it through the first positioning hole 306 on the surface of the upper fixture body 305 and the hole on the surface of the upper positioning plate 304. The lower protective pad 401 and the upper fixture body 405 are then fixed together. The protective pad 307 is made of high carbon steel, which can improve the strength of the contact surface between the upper fixture mechanism 3 and the lower fixture mechanism 4, and reduce the wear of the whole device during use. The hydraulic cylinder 1 is connected to the hydraulic equipment to provide downward pressure, pushing the upper fixture mechanism 3 to move downward along the guide rod 5. The hot riveting head 308 of the upper fixture mechanism 3 contacts the rivets or rivets on the circuit board. The hot riveting head 308 is connected to a heating element and a control circuit to heat the rivets or rivets to a certain temperature and soften them. Under the pressure provided by the hydraulic cylinder 1, the softened rivets or rivets are pressed into the riveting points of the circuit board, deforming and fixing them, thereby realizing the connection between the components. After the hot riveting is completed, the hydraulic cylinder 1 retracts, the upper fixture mechanism 3 moves upward along the guide rod 5, returns to the initial position, and the processed circuit board is taken out for the next hot riveting operation.
