Description

Technical Field

[0001] This utility model relates to the field of electronic manufacturing, and in particular to an adjustable electronic component welding fixture. Background Technology

[0002] In component soldering operations within the electronics manufacturing industry, traditional soldering fixtures suffer from numerous technical shortcomings: most fixtures employ fixed clamping structures, adapting only to single-sized electronic components. Frequent fixture changes are necessary for components of different sizes, reducing soldering efficiency and increasing equipment investment costs. Furthermore, the clamping components are often made of rigid materials, lacking cushioning and protection designs, easily scratching component casings or causing component deformation during clamping, affecting the quality and performance of the soldered components. Simultaneously, soldering generates large amounts of harmful fumes. Traditional fixtures lack corresponding fume treatment devices, causing fumes to accumulate near the workstation, obstructing operator visibility, reducing soldering accuracy, harming operator health, and polluting the working environment. These problems severely restrict the efficiency, safety, and quality of electronic component soldering operations, necessitating a new type of soldering fixture with flexible adaptability, component protection, and fume treatment capabilities.

[0003] While existing technologies can achieve a certain clamping effect during use, they suffer from the following drawbacks: they lack a clamping design with strong adaptability and protective functions, as well as a matching flue gas purification function. In view of this, we propose an adjustable electronic component welding fixture to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing an adjustable electronic component welding fixture.

[0005] The technical solution of this utility model is as follows: An adjustable electronic component welding fixture includes a mounting plate, a mounting base, a gear, and a rack. The mounting base is fixedly connected to the upper outer wall of the mounting plate. The mounting plate has a first mounting groove. A rotary motor is fixedly connected to one side of the groove of the first mounting groove. The output shaft of the rotary motor is fixedly connected to the rotation center of the gear. The upper outer wall of the mounting base has a second mounting groove. The second mounting groove has two limiting blocks. A rack is provided between the limiting blocks and the first mounting groove. The rack meshes with the gear and drives the rotary motor to make the rack move the clamping blocks simultaneously towards or away from each other, thereby clamping or unlocking the electronic component.

[0006] When using one of the adjustable electronic component welding fixtures in this solution, first place the electronic component to be welded on the second rubber pad at the top of the mounting base. Press the button on the mounting plate to start the rotating motor. The motor drives the gear to rotate, and the rack meshing with the gear moves under the guidance of the limit block, thereby causing the clamping blocks to move towards each other until the first rubber pad adheres to the component and is securely clamped. Then, press the button again to start the air pump. The air pump generates negative pressure suction, which is transmitted through the pipe to the through hole of the mounting base, drawing the welding fumes into the pipe, and then expelling them from the downward-sloping exhaust port through the connecting pipe. After welding is completed, press the button to turn off the air pump and rotating motor. The motor rotates in reverse, causing the clamping blocks to move backward to unlock, and the component can be removed. The entire process requires no external power supply; the battery provides stable power, making operation convenient and protecting the components while purifying the environment.

[0007] Preferably, a clamping block is fixedly connected to one end of the rack, a first rubber pad is fixedly connected to one side of the outer wall of the clamping block, and a plurality of second rubber pads are fixedly connected to the upper outer wall of the mounting base. The first rubber pad reduces the damage caused by the clamping block when clamping the electronic component, and the second rubber pads support the bottom of the electronic component and reduce the wear on the bottom of the electronic component.

[0008] Preferably, the mounting base has two sets of symmetrical through holes, and a set of pipes is fixedly connected to the outer walls on both sides of the mounting base. The pipes are connected to the corresponding through holes, and the through holes are distributed on both sides of the second mounting groove to effectively absorb the fumes generated during welding.

[0009] Preferably, two symmetrical air pumps are fixedly connected to the upper outer wall of the mounting plate. The air pumps are fixedly connected to one end of the pipe, and the air pumps draw gas into the upper end of the through hole.

[0010] Preferably, one side of the outer wall of the air pump is fixedly connected to one end of the connecting pipe, the other end of the connecting pipe is fixedly connected to one side of the outer wall of the exhaust port, the exhaust port is fixedly connected to the upper outer wall of the mounting plate, and the gas drawn in by the air pump is discharged from the exhaust port, with the exhaust port angled downwards.

[0011] Preferably, the lower outer wall of the mounting plate is provided with two symmetrical batteries, and the lower outer wall of the mounting plate is provided with multiple bases evenly distributed. The batteries provide power to the entire device, and the bases increase the overall stability of the device.

[0012] Preferably, a button is fixedly connected to the upper outer wall of the mounting plate, and the button is connected to various devices via wiring.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] I. This utility model employs a gear and rack meshing transmission structure in conjunction with a rotating motor drive, enabling two sets of clamping blocks to precisely achieve opposite clamping or back-to-back unlocking actions. It can flexibly adapt to the fixing needs of electronic components of different sizes, solving the problem of poor adaptability of traditional clamps to components of different specifications, and greatly improving the versatility of the clamps. At the same time, the first rubber pad on one side of the clamping block and the second rubber pad on the upper end of the mounting base form a double protection structure. The first rubber pad prevents the component shell from being scratched or deformed by force during clamping through elastic buffering, while the second rubber pad provides flexible support to the bottom of the component to reduce hard friction, effectively protecting the electronic components from damage during the soldering process and ensuring the quality of the components after soldering.

[0015] II. Based on the first beneficial effect, this utility model is equipped with a highly efficient fume treatment system. The through holes on the mounting base are evenly distributed on both sides of the welding area. Combined with the negative pressure suction generated by the air pump, the welding fumes can be quickly drawn into the pipe and then discharged from the downward-sloping exhaust port through the connecting pipe. Under the premise that the components are firmly fixed and the welding operation can be carried out accurately, this design avoids the accumulation of fumes near the welding station. This not only prevents the fumes from affecting the operator's vision and causing a decrease in welding accuracy, but also reduces the harm of fumes to the operator's health, while reducing the pollution to the working environment, and further improving the safety and comfort of welding operations.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Example 1

[0028] Please see Figures 1-4 As shown, this embodiment is an adjustable electronic component welding fixture, including a mounting plate 5, a mounting base 3, a gear 11, and a rack 9. The mounting base 3 is fixedly connected to the upper outer wall of the mounting plate 5. The mounting plate 5 has a first mounting groove 12. A rotary motor 7 is fixedly connected to one side of the groove surface of the first mounting groove 12. The output shaft of the rotary motor 7 is fixedly connected to the rotation center of the gear 11. The upper outer wall of the mounting base 3 has a second mounting groove 18. The second mounting groove 18 has two limiting blocks 19. A rack 9 is provided between the limiting blocks 19 and the first mounting groove 12. The rack 9 meshes with the gear 11. In use, the operator starts the rotary motor 7 through the control button 10. The gear 11 rotates synchronously with the output shaft. Under the guidance and restriction of the limiting blocks 19, the meshing rack 9 moves smoothly along the communication area between the second mounting groove 18 and the first mounting groove 12, thereby driving the two sets of clamping blocks 1 to accurately achieve the opposite clamping or back-to-back unlocking action, adapting to the fixing requirements of electronic components of different sizes.

[0029] Example 2

[0030] Please see Figures 1-4As shown, this embodiment further includes, based on embodiment 1: a clamping block 1 is fixedly connected to one end of the outer wall of the rack 9, a first rubber pad 2 is fixedly connected to one side of the outer wall of the clamping block 1, and a plurality of second rubber pads 4 are fixedly connected to the upper outer wall of the mounting base 3. In use, the electronic component is placed on the second rubber pad 4. When the clamping block 1 clamps the electronic component, the first rubber pad 2 directly contacts the surface of the component, and buffers the clamping pressure through its own elasticity to avoid scratching or deformation of the component shell. At the same time, the second rubber pad 4 forms a flexible support for the bottom of the component, reducing the hard friction between the component and the mounting base 3 during the soldering process.

[0031] Mounting base 3 is provided with two sets of symmetrical through holes 17. A set of pipes 13 are fixedly connected to the outer walls on both sides of mounting base 3. The pipes 13 are connected to the corresponding through holes 17. During use, the welding fumes will diffuse to the surroundings. The through holes 17 are evenly distributed on both sides of the second mounting groove 18, which just covers the welding area of ​​the electronic components. The fumes can quickly enter the pipes 13 through the through holes 17, avoiding the accumulation of fumes near the welding station.

[0032] Two symmetrical air pumps 16 are fixedly connected to the upper outer wall of the mounting plate 5. The air pumps 16 are fixedly connected to one end of the pipe 13. When in use, the air pumps 16 will generate negative pressure suction after being started. The suction is transmitted to the through hole 17 through the pipe 13, which efficiently draws the fumes from the welding area into the pipe 13, providing power support for the subsequent exhaust of fumes.

[0033] One side of the outer wall of the air pump 16 is fixedly connected to one end of the connecting pipe 15, and the other end of the connecting pipe 15 is fixedly connected to one side of the outer wall of the exhaust port 14. The exhaust port 14 is fixedly connected to the upper outer wall of the mounting plate 5. When in use, the flue gas sucked in by the air pump 16 is transported to the exhaust port 14 through the connecting pipe 15. Because the exhaust port 14 is set at an angle downward, the exhaust gas will diffuse towards the ground, which avoids directly blowing on the operators and reduces the range of flue gas pollution to the working environment.

[0034] Two symmetrical batteries 8 are provided on the lower outer wall of the mounting plate 5. Multiple bases 6 are evenly provided on the lower outer wall of the mounting plate 5. When in use, the batteries 8 can provide stable power to the rotating motor 7 and the air pump 16 without external power supply, so that the device can be flexibly moved to different working positions. At the same time, the multiple bases 6 are in close contact with the ground, increasing the friction between the device and the ground, effectively offsetting the vibration generated during welding and preventing the device from shifting.

[0035] A button 10 is fixedly connected to the upper outer wall of the mounting plate 5. When in use, the button 10 forms a control circuit with the rotating motor 7, the air pump 16 and the battery 8 through the built-in circuit. The operator can start and stop the motor and turn the air pump 16 on and off by pressing the button 10.

[0036] Instructions for use: When using this device, first place the electronic component to be soldered on the second rubber pad 4 on the upper end of the mounting base 3. Press button 10 on the mounting plate 5 to start the rotating motor 7. The motor drives the gear 11 to rotate, and the rack 9 meshing with the gear 11 moves under the guidance of the limit block 19, thereby driving the clamping block 1 to move towards the opposite side until the first rubber pad 2 adheres to the component and clamps it securely. Then, press button 10 again to start the air pump 16. The air pump 16 generates negative pressure suction, which is transmitted through pipe 13 to the through hole 17 of the mounting base 3, drawing the welding fumes into pipe 13, and then expelling them from the downward-sloping exhaust port 14 through connecting pipe 15. After the welding is completed, press button 10 to turn off the air pump 16 and the rotating motor 7. The motor rotates in reverse, causing the clamping block 1 to move backward to unlock, and the component can be removed. The entire process does not require an external power supply. The battery 8 provides stable power, making the operation convenient and protecting the components while purifying the environment.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
