Description

Technical Field

[0001] This utility model relates to the field of laser nozzle technology, and in particular to a laser nozzle disassembly and assembly mechanism. Background Technology

[0002] A laser solder ball nozzle is a precision component used in laser soldering processes. It is primarily used to melt solder balls using laser heating and then propel them to the solder joint using inert gas pressure, thus completing the soldering process. This technology is widely used in electronic components, precision devices, and semiconductor manufacturing, offering advantages such as high precision, high efficiency, and zero pollution.

[0003] In existing technologies, the nozzle is connected to the laser cladding head via threads. Over long-term use, the threaded connection may harden due to heat and scale buildup, leading to thread deformation. When the nozzle needs replacement, the torque applied during disassembly and assembly may further damage the threads, or even cause air leaks. Therefore, we propose a laser nozzle disassembly and assembly mechanism to solve these problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a laser nozzle assembly and disassembly mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

Two arc-shaped locking blocks are fixedly connected to the outer wall of the nozzle body. Two arc-shaped contact blocks are fixedly connected to the outer wall of the connector. Limiting blocks are fixedly connected to the outer walls of the two arc-shaped contact blocks. Two vertical grooves are formed on the outer wall of the connector. Rectangular blocks are slidably connected to the inner walls of the two vertical grooves. Limiting components are provided on the outer wall of the connector.

[0007] Preferably, the limiting component includes two side blocks, the outer walls of the two rectangular blocks are fixedly inlaid with the same ring, the bottom of the ring is fixedly connected to the top of the two side blocks, and the nozzle body is rotated and limited by setting the limiting component.

[0008] Preferably, a laser emitter is fixedly embedded in the top of the mounting base, and a circular hole is opened in the top of the mounting base. A solder supply tube is fixedly connected to the inner wall of the circular hole, and one end of the solder supply tube is fixedly connected to the outer wall of the laser emitter.

[0009] Preferably, a metal sealing gasket is placed on the top of the nozzle body, and the top of the metal sealing gasket is pressed against the inner wall of the connector. The sealing between the nozzle body and the connector is increased by setting the metal sealing gasket.

[0010] Preferably, the outer walls of the two arc-shaped contact blocks are slidably connected to the outer walls of the two arc-shaped locking blocks respectively, and the outer wall of one end of the arc-shaped contact block is chamfered to facilitate the arc-shaped locking block to be inserted into the top of the arc-shaped contact block.

[0011] Preferably, the inner wall of the ring is slidably connected to the outer wall of the connector.

[0012] Preferably, the two side blocks are located on one side of the two arc-shaped contact blocks.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Depend on Figures 1-6 As shown, a laser nozzle assembly / disassembly mechanism is disclosed, comprising a hollow mounting base 1, with multiple mounting holes 2 on the outer wall of the mounting base 1, a laser emitter 3 fixedly embedded in the top of the mounting base 1, and a circular hole on the top of the mounting base 1, with a solder supply tube 4 fixedly connected to the inner wall of the circular hole, one end of the solder supply tube 4 being fixedly connected to the outer wall of the laser emitter 3.

[0025] The bottom of the mounting base 1 is fixedly connected to the connector 5. The nozzle body 6 is slidably connected to the inner wall of the connector 5. The connector 5 is used for the fixed installation of the nozzle body 6. A metal sealing gasket 7 is placed on the top of the nozzle body 6. The top of the metal sealing gasket 7 is pressed against the inner wall of the connector 5. The metal sealing gasket 7 increases the sealing of the contact surface between the connector 5 and the nozzle body 6.

[0026] Two arc-shaped locking blocks 8 are fixedly connected to the outer wall of the nozzle body 6, and two arc-shaped contact blocks 9 are fixedly connected to the outer wall of the connector 5. The arc-shaped locking blocks 8 and the arc-shaped contact blocks 9 are locked together. The outer walls of the two arc-shaped contact blocks 9 are slidably connected to the outer walls of the two arc-shaped locking blocks 8 respectively. The outer walls of the two arc-shaped contact blocks 9 are fixedly connected to the limiting blocks 10. The limiting blocks 10 enable the arc-shaped locking blocks 8 and the arc-shaped contact blocks 9 to be aligned. Two vertical grooves 11 are opened on the outer wall of the connector 5. Rectangular blocks 12 are slidably connected to the inner walls of the two vertical grooves 11. The two rectangular blocks 12 move up and down along the two vertical grooves 11, driving the ring 13 to move up and down in a straight line.

[0027] The outer wall of the connector 5 is provided with a limiting component, which includes two side blocks 14. The outer walls of the two rectangular blocks 12 are fixedly inlaid with the same ring 13. The bottom of the ring 13 is fixedly connected to the top of the two side blocks 14. The inner wall of the ring 13 is slidably connected to the outer wall of the connector 5. The two side blocks 14 are respectively located on one side of the two arc-shaped contact blocks 9. The side blocks 14 limit the horizontal rotation of the arc-shaped contact blocks 9.

[0028] Working principle: During use, the mounting base 1 is fixed to the welding head of the laser solder ball welding machine (DY-D-LD(60-150)) through multiple mounting holes 2. When replacing the nozzle body 6, the ring 13 (which moves vertically through two vertical grooves 11 and two rectangular blocks 12) is moved upward, simultaneously driving the two side blocks 14 upward, releasing the rotation limit of the two arc-shaped locking blocks 8. The nozzle body 6 is then rotated to allow the two arc-shaped locking blocks 8 to slide off the outer wall of the two arc-shaped contact blocks 9. Finally, the nozzle body is... The top of nozzle 6 slides out from the inside of connector 5, and then the metal sealing gasket 7 on the top of the new nozzle body 6 is inserted into the inside of connector 5. The nozzle body 6 is rotated so that the two arc-shaped locking blocks 8 on the outer wall slide into the two arc-shaped contact blocks 9 respectively. The two limiting blocks 10 prevent the arc-shaped locking blocks 8 from sliding further, preventing the arc-shaped locking blocks 8 from separating from the arc-shaped contact blocks 9. Then the ring 13 drives the two side blocks 14 to move downward so that the two side blocks 14 are located on one side of the two arc-shaped locking blocks 8 respectively, and rotates and limits them.
