[0002] Solder sheets (pre-formed solder sheets) are thin sheets of metal or alloy pre-processed into specific shapes, typically as thin as 0.05 mm. Their core function is to wet the surface of the materials to be soldered by heating and melting them, forming a strong electrical and mechanical connection. A stamping device is an essential piece of machinery in the production of solder sheets.

[0003] In existing stamping equipment, the stamping head is generally fixed and installed using screws, and at least two screws are usually required when installing the stamping head. The stamping head needs to be replaced after a long period of use, or when stamping different shaped solder sheets. Disassembling and assembling the stamping head requires removing and installing screws, which is quite troublesome. Utility Model Content

A clamping mechanism, which is an elastic telescopic structure, is provided in two symmetrically installed in two grooves. The clamping mechanism is used to achieve a detachable connection between the stamping head and the mounting sleeve. A guide plate is fixedly provided on one adjacent end of each of the two clamping mechanisms. The upper and lower edges of the opposite side of the guide plate are chamfered, and the chamfer angle is the same as that of the first and second connectors. A clamping block is installed on the opposite side of the guide plate and clamps the outside of the connecting rod. In its natural state, there is a gap between the two clamping blocks.

[0006] Preferably, the clamping mechanism includes a telescopic rod installed on the wall of the groove, a guide plate is fixedly connected to the telescopic end of the telescopic rod, and a spring sleeved on the outside of the telescopic rod is fixedly connected between the wall of the groove and the guide plate.

[0007] Preferably, the clamping block is arc-shaped, and a rubber pad is fixedly bonded to the side that contacts the connecting rod.

[0008] Preferably, a base is welded to the bottom of the fixing frame, and a stamping table is fixedly installed at the top center of the base. The stamping table is located directly below the stamping head. A feeding mechanism installed on the base is provided on one side of the stamping table for automatic feeding.

[0013] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0014] This device enables quick replacement of the punch head. Under the combined action of the clamping mechanism, clamping block, chamfered guide plate, and connecting rod, the clamping mechanism is an elastic telescopic component that can drive the clamping block to clamp the middle of the connecting rod and restrict it between the first and second connecting heads. While clamping the connecting rod, it prevents the connecting rod from falling in the vertical direction. Furthermore, the top and bottom edges of the guide plate and the connecting plate are chamfered, which can push open the guide plate during replacement to facilitate the entry and exit of the connecting rod into and out of the mounting sleeve, ensuring that the connecting rod is not easily dropped while also being able to be pulled out.

[0020] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0021] Example 1

[0022] like Figure 1 , Figure 2 , Figure 3 As shown, this utility model provides an automatic feeding and stamping structure for solder sheets, including a fixed frame 2. A cylinder 3 is fixedly installed on the top of the fixed frame 2. An installation sleeve 4 is installed on the output end of the cylinder 3. A stamping head 5 is detachably connected inside the installation sleeve 4. A movable groove 401 is vertically opened on the bottom surface of the installation sleeve 4. Grooves 402 are symmetrically opened on both sides inside the installation sleeve 4. The movable groove 401 and the grooves 402 are interconnected. A connecting rod 6 is installed inside the installation sleeve 4. The connecting rod 6 has an I-shaped cross-section and is vertically inserted into the movable groove 401. The connecting rod 6 includes a cylindrical connecting rod 603. A square second connecting head 602 is fixedly connected to the top of the connecting rod 603, and a first connecting head 601 is fixedly connected to the bottom. The first connecting head 601... A stamping head 5 is fixedly connected to the bottom. The upper and lower edges of both sides of the second connector 602 are chamfered. The shape and size of the second connector 602 are the same as those of the first connector 601. A clamping mechanism 10 is symmetrically installed in the two grooves 402. The clamping mechanism 10 is an elastic telescopic structure used to realize the detachable connection between the stamping head 5 and the mounting sleeve 4. A guide plate 11 is fixedly provided on the adjacent end of the two clamping mechanisms 10. The upper and lower edges of the opposite side of the guide plate 11 are chamfered, and the chamfer angle is the same as that of the first connector 601 and the second connector 602. A clamping block 12 is installed on the opposite side of the two guide plates 11. The clamping block 12 is clamped to the outside of the connecting rod 603. In the natural state, there is a gap between the two clamping blocks 12.

[0023] In this embodiment, when installing the stamping head 5, the second connector 602 is aligned with the movable slot 401. The chamfer on the top edge of the second connector 602 contacts the chamfer on the bottom edge of the guide plate 11. The second connector 602 is pushed upward, and the second connector 602 squeezes the guide plate 11. During the movement of the second connector 602, the squeezed guide plate 11 moves to both sides. The guide plate 11 drives the clamping blocks 12 to move to both sides. After the two clamping blocks 12 open, the second connector 602 enters between the two clamping blocks 12 and continues to squeeze the guide plate 11 through the clamping blocks 12. The guide plate 11 compresses the clamping mechanism 10. When the second connector 602 moves to the point where it can no longer move... When in motion, it no longer contacts the clamping block 12. Under the action of the clamping mechanism 10, its rebound drives the clamping block 12 to move, so that the clamping block 12 is stuck outside the connecting rod 603. At this time, the first connecting head 601 and the second connecting head 602 restrict the clamping block 12 between them, and the clamping block 12 clamps the connecting rod 603. The entire connecting rod 6 is not easy to fall out of the mounting sleeve 4. When disassembling the stamping head 5, the stamping head 5 is pulled down, and the stamping head 5 drives the second connecting head 602 to move down. The chamfer set at the bottom edge of the second connecting head 602 contacts the chamfer set at the top edge of the guide plate 11, and squeezes the guide plate 11, so that the guide plate 11 opens to both sides. Then the connecting rod 6 can be pulled out.

[0024] This embodiment enables the rapid replacement of the punch head 5. Under the combined action of the clamping mechanism 10, the clamping block 12, the chamfered guide plate 11, and the connecting rod 6, the clamping mechanism 10 is an elastic telescopic component. It can drive the clamping block 12 to clamp the middle of the connecting rod 6 and restrict it between the first connecting head 601 and the second connecting head 602. While clamping the connecting rod 6, it makes it difficult for the connecting rod 6 to fall in the vertical direction. Furthermore, the top and bottom edges of the guide plate 11 and the connecting plate are chamfered. During replacement, the guide plate 11 can be pushed open to facilitate the entry and exit of the connecting rod 6 into and out of the mounting sleeve 4, so that the connecting rod 6 is not easy to fall while also being able to be pulled out.

[0025] Example 2

[0026] This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those described above will not be repeated here. Figure 2 , Figure 3 As shown, in order to better realize this utility model, the following configuration is adopted: In this embodiment, the clamping mechanism 10 includes a telescopic rod 1001 installed on the wall of the groove 402. A guide plate 11 is fixedly connected to the telescopic end of the telescopic rod 1001. A spring 1002 sleeved on the outside of the telescopic rod 1001 is fixedly connected between the wall of the groove 402 and the guide plate 11.

[0027] The clamping block 12 is arc-shaped, and a rubber pad is fixedly bonded to the side that contacts the connecting rod 603.

[0028] In this embodiment, during use, the second connector 602 presses against the clamping block 12, and the clamping block 12 drives the guide plate 11 to press against the telescopic rod 1001 and the spring 1002. The spring 1002 deforms under force, and then the second connector 602 separates from the clamping block 12. Under the action of the spring 1002, its rebound causes the clamping block 12 to be locked on the outside of the connecting rod 6. When the clamping block 12 clamps the connecting rod 6, the connecting rod 6 is cylindrical and the clamping block 12 is arc-shaped, which can fit against the outer surface of the connecting rod 6 and clamp it firmly. The rubber pads adhered to the clamping block 12 can increase the friction between the clamping frame and the connecting rod 6 and improve the stability of the clamping.

A second servo motor 904 is fixedly mounted on the outer surface of the second fixed plate 901. One end of one of the second rotating rollers 902 is fixedly connected to the output end of the second servo motor 904.

[0033] The height of the first conveyor belt 803 is the same as the height of the stamping table 7.

[0034] The height of the second conveyor belt 903 is the same as the height of the stamping table 7.

[0035] In this embodiment, during use, the long sheet of raw material is placed on the first conveyor belt 803. Simultaneously, the first servo motor 804 and the second servo motor 904 are started. The first servo motor 804 drives the first rotating roller 802 connected to it to rotate. The first rotating roller 802 drives the first conveyor belt 803 to rotate. The first conveyor belt 803 drives another first rotating roller 802 to rotate. At the same time, the first conveyor belt 803 transports the raw material. The working principle of the conveying mechanism 9 is the same as that of the feeding mechanism 8, and will not be described in detail here. The cylinder 3 is started, and the cylinder 3 drives the punch head 5 to move down. The raw material is transported to the punching table 7, where the punch head 5 punches it. The finished product falls into the unloading hole through the punching hole on the punching table 7. The finished product can be collected by placing a collection box under the base 1. The waste material after punching is continued to be transported to the second conveyor belt 903. The second conveyor belt 903 transports the waste material, which is convenient for waste material collection. The height of the first conveyor belt 803 and the second conveyor belt 903 is the same as the height of the punching table 7, which is to facilitate the transport of raw material and waste material.
