[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figure 1 As shown;

[0028] A uniformly heated wire welding hot press plate includes a mounting base 1. In this embodiment, while this design allows for quick fixation of semiconductors by driving two fixing plates toward each other along guide rods via a bidirectional screw, making operation more convenient and improving work efficiency, the aforementioned device only heats the bottom of the material and fails to provide a more uniform heating environment. This results in uneven heating of the material during welding, making it prone to localized overheating or overcooling, which can lead to welding defects such as cracks and pores. To address this technical issue, a heating assembly 2 is added to this basis.

[0029] Furthermore, if Figures 1 to 6As shown, combined with the above content: the heating component 2 includes a first motor 21, a connecting piece 22 and a first bevel gear 23, the first motor 21 is installed on the inner side of the bottom end of the mounting base 1, the outer side of the end of the first motor 21 is fixedly connected to the connecting piece 22, one side of the connecting piece 22 is rotatably connected to the first bevel gear 23, the inner side of one end of the connecting piece 22 is rotatably connected to the second bevel gear 24, the upper surface of the second bevel gear 24 is fixedly connected to a connecting rod 25, the inner side of the top end of the connecting piece 22 is rotatably connected to the third bevel gear 26, one side of the third bevel gear 26 is fixedly connected to a rod sleeve 27, the outer side of one end of the rod sleeve 27 is fixedly connected to a heating frame 28, the outer side of the connecting rod 25 is rotatably connected to the inner side of the rod sleeve 27, the first bevel gear 23 is meshed with the third bevel gear 26 and the second bevel gear 24 respectively, and the connecting rod 25 is connected to the inner side of the rod sleeve 27. A connecting disk 29 is fixedly connected to the outer side of the top end of the rod 25, a heating strip 210 is installed on the inner side of the bottom end of the heating frame 28, a fixing frame 211 is fixedly connected to the upper surface of the connecting disk 29, a second motor 212 is installed on the upper surface of the connecting disk 29, a rotating disk 213 is fixedly connected to the outer side of the main shaft of the second motor 212, a plurality of rotating arms 214 are rotatably connected to the upper surface of the rotating disk 213, a clamping block 215 is rotatably connected to the outer side of the end of the rotating arm 214, a placing plate 216 is fixedly connected to the outer side of the end of the fixing frame 211, the outer sides of both ends of the clamping block 215 are slidably connected to the inner side of the end of the placing plate 216, a clamping strip 217 is fixedly connected to one side of the placing plate 216, and the material of the clamping strip 217 is rubber. A plurality of heating strips 210 are evenly installed on the inner wall surface of the heating frame 28.

At this time, the user can start the second motor 212, and the second motor 212 drives the rotating disk 213 on the outer side of its main shaft to rotate. When the rotating disk 213 rotates, it will simultaneously pull multiple rotating arms 214 to rotate toward the middle. When the rotating arms 214 rotate, they will simultaneously pull multiple clamping blocks 215 to clamp toward the middle, thereby fixing the material. At the same time, the clamping rubber strip 217 can increase the friction between the material and the clamping rubber strip 217. When heating starts, the user can start the first motor 21, and the first motor 21 drives the second bevel gear 24 on the outer side of its main shaft to rotate. When the second bevel gear 24 rotates, it will drive the connecting rod 25 on its upper surface to rotate. When the second bevel gear 24 rotates, it will drive the first bevel gear 23 meshed with it to rotate. When the first bevel gear 23 rotates, it will drive the third bevel gear 26 meshed with the first bevel gear 23 to rotate. When the heating element 2 is in operation, the rod sleeve 27 on the upper surface of the third bevel gear 26 will be driven to rotate, thereby driving the heating frame 28 and the connecting disk 29 to rotate relative to each other, thereby increasing the heating efficiency. The uniform heating of the heating component 2 ensures that the material is heated evenly during operation, avoiding welding defects caused by local overheating or overcooling. The clamping block 215 ensures the stability of the material during heating and rotation, prevents the material from moving or offsetting, thereby ensuring the accuracy and consistency of the material position. The relative rotation function further promotes the uniform heating of the processing surface and the full mixing of the metals, thereby improving the quality and strength of the material. The fast fixing and releasing function of the clamping block 215 shortens the time for material preparation and replacement, and improves the continuity and efficiency of the production line. At the same time, the automated operation of relative rotation reduces manual intervention, making the entire processing process smoother and more efficient. The rationally designed clamping block 215 and rotation control system allow operators to easily complete operations such as fixing, rotating and removing materials, reducing the difficulty of operation and skill requirements.

[0031] Working principle: When using the device, the user can place the material to be fixed on the upper surface of the placement plate 216. At this time, the user can start the second motor 212. The second motor 212 drives the rotating disk 213 outside its main shaft to rotate. When the rotating disk 213 rotates, it will simultaneously pull multiple rotating arms 214 to rotate toward the middle. When the rotating arms 214 rotate, they will simultaneously pull multiple clamping blocks 215 to clamp toward the middle, thereby fixing the material. At the same time, the clamping rubber strip 217 can increase the friction between the material and the material. When starting to heat, the user can start the first motor 21. The first motor 21 drives the second bevel gear 24 outside its main shaft to rotate. The second bevel gear 24 rotates. At the same time, it will drive the connecting rod 25 on its upper surface to rotate. When the second bevel gear 24 rotates, it will drive the first bevel gear 23 meshed with it to rotate. When the first bevel gear 23 rotates, it will drive the third bevel gear 26 meshed with the first bevel gear 23 to rotate. When the third bevel gear 26 rotates, it will drive the rod sleeve 27 on the upper surface of the third bevel gear 26 to rotate, and then drive the heating frame 28 and the connecting disk 29 to rotate relative to each other, thereby increasing the heating efficiency. The uniform heating of the heating assembly 2 ensures that the material is heated evenly during operation, avoiding welding defects caused by local overheating or overcooling. The clamping block 215 ensures the stability of the material during the heating and rotation process, preventing The relative rotation function further promotes uniform heating of the processing surface and sufficient mixing of the metals, thereby improving the quality and strength of the materials. The fast fixing and releasing function of the clamping block 215 shortens the time for material preparation and replacement, and improves the continuity and efficiency of the production line. At the same time, the automatic operation of relative rotation reduces manual intervention, making the entire processing process smoother and more efficient. The rationally designed clamping block 215 and the rotation control system allow the operator to easily complete operations such as fixing, rotating and removing the materials, reducing the difficulty of operation and skill requirements. The support legs 2 are installed for the above-mentioned uniformly heated welding wire hot press plate. 18. The many benefits it brings are significant and important. First, the support legs 218 can provide a stable support base to ensure that the hot press plate remains stable and does not shake during operation, which is crucial for high-precision semiconductor wire bonding operations and can effectively avoid welding deviations or quality problems caused by equipment shaking. Secondly, the design of the support legs 218 can be adjusted according to actual work needs to enable the hot press plate to reach a suitable working height, thereby improving the operator's comfort and work efficiency.
