Description

Technical Field

[0001] The present invention relates to the technical field of mobile phone welding jigs, and particularly to a jig for mobile phone laser welding provided with a jet-type welding slag cleaning structure. Background Art

[0002] A mobile phone, also known as a mobile telephone or wireless telephone, is usually called a cell phone. It was originally just a communication tool. With the development of society and technology, mobile phones have become increasingly intelligent and are now one of the essential items in people's daily lives. During the manufacturing process of mobile phones, laser welding technology is used to weld various components onto the circuit board. In this process, a mobile phone welding jig is required to fix the mobile phone circuit board or motherboard to facilitate subsequent welding operations.

[0003] However, for current mobile phone welding jigs, they do not have a flipping and jetting structure.

[0014] Beneficial effects

[0015] When the device is in use, the jet side plate can eject the cleaning gas provided by the air supply device near the fixture seat, so that the welding slag can be removed in real time following the welding operation, which is flexible and convenient to use. At the same time, the fixture seat can be freely flipped 180 degrees for use, so that there is no need to repeatedly install and disassemble the circuit board during double-sided welding of the circuit board, simplifying the operation process, greatly improving the work efficiency, and the flipping action of the fixture seat is located in the top space of the fixed seat when flipping, so there is no need to provide a large flipping space for the fixture seat, reducing the occupied space of the device and improving the flexibility, adaptability and practicability of the device.

[0016] In addition, the mobile phone circuit board to be welded can be positioned and fixed through the clamping block, which is convenient to use. The position of the clamping block can be adjusted through the adjusting rod, facilitating the installation and disassembly operation of the circuit board. When the adjusting rod is rotated, the thread of the adjusting rod body can drive the clamping block to move through the track block to change the size of the clamping distance formed with the fixture seat, thus realizing the installation and disassembly operation of the circuit board, and the operation is simple.

[0017] In addition, when the device is in the reset state, the control rod can lock the use state of the fixture seat. When the control rod is in the reset state, under the action of the positioning top spring, the limiting rod is inserted into the inside of the guiding groove, and at this time, the use position of the limiting rod is blocked by the variable diameter groove, so that the fixture seat can be positioned to the horizontal state for use, facilitating various welding operations. And at this time, the force application rod of one set of starting components is squeezed by the cross plate of the fixture seat, so that the force application rod is hidden inside the mounting seat to compress the force application top spring for energy storage, so as to provide a starting guiding force for the fixture seat when flipping and adjusting the fixture seat subsequently, avoiding the structural dead point resulting in the device being stuck, and the use is stable.

[0018] In addition, when it is necessary to flip and adjust the fixture seat to weld the other side of the circuit board, just press the control rod. At this time, the avoiding rod enters the inside of the guiding groove, and the avoiding rod can freely pass through the inside of the variable diameter groove. So at this time, pulling the control rod can drive the fixture seat to flip. When pressing and pulling the control rod, the control rod can move horizontally inside the guiding groove. So at this time, under the driving cooperation of the two rotating shafts of the guiding rod and the control rod, the fixture seat can be driven to turn up for turning over and using. After the flipping is completed, release the control rod, and the control rod can push the limiting rod back into the other end of the guiding groove under the action of the positioning top spring and limit the use position of the control rod through the variable diameter groove. At the same time, at this time, the fixture seat will press down the force application rod of the other set of starting components to compress the force application top spring for energy storage, with stable use, convenient adjustment, simplifying the operation process of double-sided welding of the mobile phone circuit board, and greatly improving the work efficiency.

The air jet side plate 103 in the middle can eject the cleaning gas provided by the air supply device from near the fixture seat 201, so that the welding slag can be removed in real time following the welding operation, and the use is flexible and convenient.

[0042] In addition, according to an embodiment of the present invention, as Figure 4As shown, a guiding groove 1021 is provided inside the plate body of the guiding side plate 102, and the control rod 205 is inserted into the guiding groove 1021. The control rod 205 is composed of a limiting rod 2051 and an avoiding rod 2052. The limiting rod 2051 is inserted into the side plate b212, and the avoiding rod 2052 is fixedly installed at the outer end of the limiting rod 2051. Variable-diameter grooves 1022 are provided inside both sides of the groove body of the guiding groove 1021. The outer diameter of the rod body of the limiting rod 2051 is larger than the outer diameter of the rod body of the avoiding rod 2052. The inner diameter of the groove body of the guiding groove 1021 is the same as the outer diameter of the rod body of the limiting rod 2051, and the inner diameter of the groove body of the variable-diameter groove 1022 is the same as the outer diameter of the rod body of the avoiding rod 2052. During use, when the device is in the reset state, the control rod 205 can lock the use state of the fixture seat 201. When the control rod 205 is in the reset state, under the action of the positioning spring 20511, the limiting rod 2051 is inserted into the guiding groove 1021, and at this time, the use position of the limiting rod 2051 is blocked by the variable-diameter groove 1022, so that the fixture seat 201 can be positioned to the horizontal state for use, facilitating various welding operations. A force-applying spring 3021 is provided at the bottom of the force-applying rod 302, and both ends of the force-applying spring 3021 are fixedly connected to the inside of the mounting seat 301 and the bottom of the force-applying rod 302 respectively. At this time, the force-applying rod 302 of one group of starting assemblies 3 is squeezed by the cross plate of the fixture seat 201, so that the force-applying rod 302 is hidden inside the mounting seat 301 to compress the force-applying spring 3021 to store energy, so as to provide a starting guiding force for the fixture seat 201 when the fixture seat 201 is turned and adjusted later, avoiding the occurrence of structural dead points that cause the device to jam, and the use is stable.

[0043] In addition, according to an embodiment of the present invention, as Figure 4As shown, a positioning top spring 20511 is provided inside the rod body of the limit rod 2051, and both ends of the positioning top spring 20511 abut against the inside of the side plate b212 and the inside of the limit rod 2051 respectively. During use, when it is necessary to flip and adjust the fixture seat 201 to perform soldering operations on the other side of the circuit board, just press the control rod 205. At this time, the avoidance rod 2052 enters the inside of the guide groove 1021, and the avoidance rod 2052 can freely pass through the inside of the variable diameter groove 1022. Thus, pulling the control rod 205 at this time can drive the fixture seat 201 to flip. When pressing and pulling the control rod 205, the control rod 205 can move horizontally inside the guide groove 1021. Thus, at this time, under the driving cooperation of the two rotating shafts of the guide rod 204 and the control rod 205, the fixture seat 201 can be driven to turn up for flipping use. After the flipping is completed, release the control rod 205. The control rod 205 can, under the action of the positioning top spring 20511, push the limit rod 2051 back into the other end of the guide groove 1021 and limit the use position of the control rod 205 through the variable diameter groove 1022. At the same time, at this time, the fixture seat 201 will press down the force application rod 302 of the other set of starting components 3 to compress the force application top spring 3021 for energy storage. It is stable in use, convenient to adjust, simplifies the operation process of double-sided soldering of mobile phone circuit boards, and greatly improves work efficiency.

[0044] In addition, according to an embodiment of the present invention, as Figure 4 shown, the rod body of the guide rod 204 is in an "L" shape, and the control rod 205 can rotate inside the side plate b212. The rotation centers at both ends of the guide rod 204 and the rotation center of the side plate b212 are on the same straight line, and this straight line is parallel to the plate body of the side plate b212. During use, the "L" shape design of the guide rod 204 enables the guide rod 204 not to obstruct the movement track of the control rod 205 when the control rod 205 is pulled, and it is stable in use.

[0045] Specific usage method and function of this embodiment: In the present invention, first, place the mobile phone circuit board to be welded and processed inside the fixture seat 201. The clamping block 203 can position and fix the mobile phone circuit board to be welded and processed. Rotate the adjusting rod 202. When the adjusting rod 202 rotates, the thread on the rod body of the adjusting rod 202 can drive the clamping block 203 to move through the track block 2031 to change the size of the clamping distance formed with the fixture seat 201, thereby realizing the installation and removal operations of the circuit board. When the device is in the reset state, the control rod 205 can lock the usage state of the fixture seat 201. When the control rod 205 is in the reset state, under the action of the positioning spring 20511, the limiting rod 2051 is inserted into the guiding groove 1021, and at this time, the usage position of the limiting rod 2051 is blocked by the variable diameter groove 1022, so that the fixture seat 201 can be positioned to the horizontal state for use, facilitating various welding operations. And at this time, the force application rod 302 of one set of starting components 3 is squeezed by the cross plate of the fixture seat 201, so that the force application rod 302 is hidden inside the mounting seat 301 to compress the force application spring 3021 for energy storage, in order to provide a starting guiding force for the fixture seat 201 when the fixture seat 201 is flipped and adjusted later, avoiding the device being stuck due to structural dead points. The air jet side plate 103 can spray the cleaning gas provided by the air supply device from near the fixture seat 201, so that the welding slag can be removed in real time following the welding operation. After one side of the mobile phone circuit board is welded, the circuit board is flipped to the other side by this device to continue the welding and processing operation. When it is necessary to flip and adjust the fixture seat 201 to perform the welding operation on the other side of the circuit board, just press the control rod 205. At this time, the avoiding rod 2052 enters the guiding groove 1021, and the avoiding rod 2052 can freely pass through the inside of the variable diameter groove 1022. Thus, pulling the control rod 205 at this time can drive the fixture seat 201 to flip. When pressing and pulling the control rod 205, the control rod 205 can move horizontally inside the guiding groove 1021. Thus, at this time, under the driving cooperation of the two rotating shafts of the guiding rod 204 and the control rod 205, the fixture seat 201 can be driven to turn up for flipping and using. After the flipping is completed, release the control rod 205. The control rod 205 can, under the action of the positioning spring 20511, push the limiting rod 2051 back into the other end of the guiding groove 1021 and limit the usage position of the control rod 205 through the variable diameter groove 1022. At the same time, at this time, the fixture seat 201 will press down the force application rod 302 of the other set of starting components 3 to compress the force application spring 3021 for energy storage. After the welding is completed, remove this circuit board and repeat the above steps to perform the welding and processing operation on the remaining mobile phone circuit boards.

[0046] Finally, it should be noted that when the present invention describes the positions of various components and their cooperation relationships, etc., usually one / a pair of components are taken as examples. However, those skilled in the art should understand that such positions, cooperation relationships, etc. are equally applicable to other components / other pairs of components.
