Description

Technical Field

[0001] This utility model relates to the field of double-tailed needle laser welding mold technology, and in particular to a double-tailed needle laser welding mold that is easy to replace. Background Technology

[0002] A double-tailed pin is an electronic connector with two pins. In current laser welding, double-tailed pins are mostly welded by workers using specialized tweezers to place the two pins on top of the laser welding mold into the corresponding shape, and then welding the two pins on the mold using a laser welding device.

[0003] However, the vibration force generated by the laser welding device during the welding of the two tail needles can easily cause the two tail needles to deviate slightly, which in turn can cause the two tail needles to deviate during laser welding, thus affecting the accuracy of double tail needle laser welding. Utility Model Content

[0004] Therefore, it is necessary to provide a convenient double-tailed needle laser welding mold to address the problem that the two tail needles are prone to misalignment during laser welding.

[0005] The device includes: a base; a positioning mechanism, the positioning mechanism including a placement block and an installation block mounted on the top of the base, the placement block having a recessed hole on its top, a fixing block mounted on the top of the installation block, a slider slidably connected to the inner wall of the fixing block, a pressure block fixedly connected to one side of the slider, a push block hinged to the surface of the fixing block, a slide rod hinged to the inner wall of the push block, and the surface of the slide rod hinged to the inner wall of the slider.

[0006] In one embodiment, the inner wall of the base is threaded with a plurality of first bolts, one of which has its surface threaded to the inner wall of the placement block.

[0007] In one embodiment, the top of the mounting block has two movable holes, with the surface of the first bolt on one side located inside the movable hole. The movable holes and the first bolt interact to adaptively adjust the lateral position of the mounting block on the base, thereby ensuring the pressure block accurately abuts against the two tail pins and guaranteeing the effective positioning of the two tail pins.

[0008] In one embodiment, a second bolt is threaded onto the inner wall of the fixing block, and the surface of the second bolt is threaded onto the inner wall of the mounting block. The second bolt allows for the disassembly and assembly of the fixing block, slider, and pressure block on the mounting block, facilitating the replacement of the fixing block, slider, and pressure block on the base base, while ensuring the pressure block effectively resists the two tail pins.

[0009] In one embodiment, a limit ring is fixedly connected to the inner wall of the base.

[0010] In one embodiment, a sliding hole is provided at the top of the base, and the bottom of the slider is slidably connected to the inner wall of the sliding hole. The limiting ring restricts the lateral movement range of the mounting block on the base, preventing the mounting block from covering the sliding hole during lateral movement and ensuring the slider's range of motion within the sliding hole. The sliding hole limits the lateral movement of the slider, preventing it from shifting during lateral movement.

[0011] In one embodiment, the top of the base, placement block, mounting block, and fixing block are all provided with rubber gaskets. The top of one side of the rubber gasket abuts against the end of the first bolt, and the top of the other side of the rubber gasket abuts against the end of the second bolt. The rubber gaskets ensure that the first bolt is stably threaded within the base and placement block, and that the second bolt is stably threaded within the mounting block and fixing block.

[0012] In one embodiment, the surface of the pusher is covered with a soft pad.

[0013] Beneficial effects 1. By cooperating with the placement block and the concave hole, the two tail needles are initially limited, and then the two tail needles are precisely positioned. By cooperating with the mounting block, fixing block, slider, sliding rod and push block, the pressure block is pushed laterally, and then the pressure block is pressed against the two tail needles, thereby achieving stable positioning of the two tail needles, avoiding the two tail needles from shifting during laser welding, and ensuring the accuracy of double tail needle laser welding; 2. The first bolt enables the disassembly and assembly of the placement block on the base, facilitating the replacement of the placement block on the base. This ensures the precise positioning of the two tail pins by the concave holes on the placement block, reduces the offset of the two tail pins during laser welding, and ensures the accuracy of double tail pin laser welding.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The following is combined with Figures 1-5 This invention describes a conveniently replaceable double-tailed needle laser welding mold.

[0019] In one embodiment, a replaceable double-tailed needle laser welding mold includes: a base base 100; a positioning mechanism 200, the positioning mechanism 200 including a placement block 201 and a mounting block 207 mounted on the top of the base base 100, the placement block 201 having a recessed hole 202 on its top, the mounting block 207 having a fixing block 203 mounted on its top, the fixing block 203 having a slider 205 slidably connected to its inner wall, the slider 205 having a pressure block 204 fixedly connected to one side, the fixing block 203 having a push block 209 hinged to its surface, the push block 209 having a slide rod 214 hinged to its inner wall, and the slide rod 214 having its surface hinged to the inner wall of the slider 205.

[0020] In this embodiment, when laser welding of the two tail needles is required, the worker uses tweezers to place the two tail needles into the recess 202 in sequence, pushes the pusher 209, and causes the slide bar 214 to generate thrust and change angle, pushing the slider 205 and the pressure block 204 to move laterally, so that the end of the pressure block 204 abuts against the surface of the two tail needles, thereby positioning the two tail needles. At this time, the laser generator on the double tail needle laser welding machine emits a laser beam according to the preset welding parameters to weld the double tail needles. The laser energy causes the welding part of the tail needles to melt rapidly, forming a molten pool. As the laser continues to act, the molten pool gradually cools and solidifies, realizing the connection of the two tail needles.

[0021] like Figure 2-4 As shown, the inner wall of the base base 100 is threaded with several first bolts 211, one of which is threaded to the inner wall of the placement block 201. The top of the mounting block 207 has two movable holes 208, one of which is located inside the movable hole 208. The inner wall of the fixing block 203 is threaded with second bolts 215, the surface of which is threaded to the inner wall of the mounting block 207. The inner wall of the base base 100 is fixedly connected with a limit ring 213. The top of the base base 100 has a sliding hole 206, and the bottom of the slider 205 is slidably connected to the inner wall of the sliding hole 206. The tops of the base base 100, placement block 201, mounting block 207, and fixing block 203 are all provided with rubber pads 212, one of which has its top abutting against the end of the first bolt 211, and the other has its top abutting against the end of the second bolt 215.

[0022] In this embodiment, two rubber pads 212 are placed inside the base base 100 using an electric wrench, and two first bolts 211 are passed through the rubber pads 212 and threaded onto the base base 100 and the double-tailed needle laser welding machine, so that the ends of the first bolts 211 are pressed against the top of the rubber pads 212, and the base base 100 is mounted on the double-tailed needle laser welding machine.

[0023] Select a suitable size placement block 201, place two other rubber pads 212 at the end of the placement block 201, pass the first bolt 211 through the rubber pad 212 and thread it into the placement block 201 and the base base 100, so that the end of the first bolt 211 is pressed against the top of the rubber pad 212, so that the placement block 201 is installed on the base base 100.

[0024] Select a suitable size fixing block 203 and place it on top of the mounting block 207. Place the rubber gasket 212 at the end of the fixing block 203. Thread the second bolt 215 into the fixing block 203 and the mounting block 207, so that the end of the second bolt 215 abuts against the top of the rubber gasket 212. Place the mounting block 207 at a suitable position on the top of the base base 100. Place the rubber gasket 212 on top of the mounting block 207. Pass the first bolt 211 through the rubber gasket 212 and insert it into the movable hole 208. Rotate the first bolt 211 to thread it into the base base 100, so that the end of the first bolt 211 abuts against the top of the rubber gasket 212, thus mounting the mounting block 207 onto the base base 100.

[0025] When it is necessary to adjust the position of the mounting block 207 on the base base 100, rotate the first bolt 211 so that the end of the first bolt 211 moves upward away from the top of the mounting block 207 and the rubber pad 212, push the mounting block 207 to a suitable position on the top of the base base 100, rotate the first bolt 211 so that the end of the first bolt 211 moves downward and abuts against the top of the mounting block 207 and the rubber pad 212.

[0026] like Figure 2 As shown, a soft pad 210 is fitted on the surface of the push block 209.

[0027] Working principle: The worker uses tweezers to place the two tail needles into the concave hole 202 in turn, holds the soft pad 210 and pushes the push block 209, so that the slide rod 214 generates a pushing force and changes the angle, pushing the slider 205 to move laterally in the slide hole 206, so that the pressure block 204 moves laterally and abuts against the surface of the two tail needles, thereby positioning the two tail needles. At this time, the laser generator on the double tail needle laser welding machine emits a laser beam according to the preset welding parameters to weld the double tail needles.

[0028] It should be noted that the base 100, placement block 201, mounting block 207, fixing block 203, push block 209, slide bar 214, slider 205, pressure block 204, first bolt 211 and second bolt 215 mentioned above are all components with relatively mature existing technology. The specific models can be selected according to actual needs, and will not be elaborated here.

[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
