Description

Technical Field

[0001] This utility model belongs to the technical field of circuit board welding auxiliary equipment, specifically, it relates to a multi-angle circuit board spot welding auxiliary frame. Background Technology

[0002] In the modern electronics manufacturing industry, circuit board soldering is a critical step, and its quality and efficiency directly affect the performance and production cycle of electronic products. As electronic products rapidly develop towards miniaturization and multi-functionality, the electronic components on circuit boards are becoming increasingly precise and compactly arranged, which undoubtedly places extremely stringent requirements on the soldering process.

[0003] Currently, most circuit board soldering work still relies on manual operation, and the traditional method of laying the circuit board flat on a table is commonly used. In this operating mode, overhead lighting becomes a major obstacle to soldering accuracy. Because the light shines directly down, the components on the circuit board will cast obvious shadows, especially those small electronic components with fine pins. Their soldering positions are covered by shadows, making it difficult for soldering personnel to accurately position the solder joints. Even slight deviations can lead to soldering defects such as cold solder joints and short circuits. This not only increases the product defect rate but also requires additional time and cost for rework, severely restricting the improvement of production efficiency. Furthermore, after soldering, the circuit board needs to be unlocked again, resulting in slow soldering efficiency.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] A multi-angle circuit board spot welding auxiliary frame includes a mounting base, an adjustment plate rotatably mounted on the mounting base, and adjustment components and clamping components mounted on the mounting base and the adjustment plate.

[0007] The adjustment assembly includes a lead screw shaft, which is rotatably mounted on a mounting base. A horizontally sliding lead screw sleeve is engaged with the lead screw shaft, and a push rod is vertically mounted on the lead screw sleeve. The push rod is slidably connected to the bottom of the adjustment plate, and the adjustment plate is in an inclined state.

[0008] The clamping assembly includes a pair of energy storage covers, which are installed on both sides of the adjusting plate. A top rod is inserted into the inside of each energy storage cover. A clamping plate is installed at the end of each top rod, and the end of the clamping plate clamps the circuit board. A plug rod is installed on the top rod, and a sliding rod is installed at the end of the plug rod. An energy storage spring is installed between the top rod and the energy storage cover. A guide block is installed on the adjusting plate, and a ramp is installed on the guide block. The ramp and the sliding rod correspond to each other.

[0009] In a preferred embodiment of this utility model, a base is installed at the bottom of the mounting base, an anti-slip pad is installed at the bottom of the base, and a positioning plate is installed at the bottom of the adjustment plate, with the positioning plate overlapping the bottom of the circuit board.

[0010] In a preferred embodiment of this utility model, a limiting plate is installed on the side wall of the lead screw sleeve, and a limiting rod is movably installed inside the limiting plate. The two ends of the limiting rod are connected to the inner wall of the mounting base, and a knob is installed at the end of the lead screw shaft.

[0011] In a preferred embodiment of the present invention, a pair of limiting guide rails are installed at the bottom of the adjusting plate, and the end of the push rod passes through the gap between the pair of limiting guide rails. A pair of protrusions are installed at the end of the push rod, and the pair of protrusions slide in the through grooves opened on the side wall of the corresponding limiting guide rail.

[0012] In a preferred embodiment of this utility model, a power storage plate is slidably installed inside the power storage cover, and the two ends of the power storage plate are respectively connected to the insertion rod and the top rod. A power storage spring is sleeved on the top rod, one end of the power storage spring is clamped to the inner wall of the power storage cover, and the other end of the power storage spring is clamped to the power storage plate.

[0013] In a preferred embodiment of this utility model, the thickness of the guide block is greater than the length of the maximum travel of the clamping plate, and a notch is provided on the guide block, and the position of the notch is adapted to the position of the insertion rod.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] When the circuit board needs adjustment, this invention uses a lead screw shaft to drive a lead screw sleeve to slide. The push rod on the lead screw sleeve slides on an inclined adjustment plate, which in turn causes the adjustment plate on which the circuit board is mounted to deflect, thereby achieving the purpose of adjusting the angle. It also has a self-locking effect, preventing easy changes in angle and improving the stability of the equipment. After spot welding is completed, the operator can adjust the adjustment plate to a horizontal state. During this process, the slide rod can drive the ramp to slide, which in turn drives the synchronously connected insert rod and push rod to move, ultimately causing the clamping plate and circuit board to separate, automatically achieving the purpose of unlocking and improving operational efficiency.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0025] like Figures 1 to 5 As shown, a multi-angle circuit board spot welding auxiliary frame includes a mounting base 1, an adjustment plate 3 is rotatably mounted on the mounting base 1, and adjustment components and clamping components are mounted on the mounting base 1 and the adjustment plate 3.

[0026] The adjustment assembly includes a lead screw shaft 15, which is rotatably mounted on the mounting base 1. A horizontally sliding lead screw sleeve 17 is engaged with the lead screw shaft 15, and a push rod 20 is vertically mounted on the lead screw sleeve 17. The push rod 20 is slidably connected to the bottom of the adjustment plate 3, and the adjustment plate 3 is in an inclined state. When the lead screw shaft 15 rotates, it will drive the lead screw sleeve 17 to slide horizontally. The push rod 20 on the lead screw sleeve 17 slides at the bottom of the inclined adjustment plate 3, eventually squeezing the position of the adjustment plate 3 and causing it to deflect. The adjustment plate 3 then rotates around the mounting base 1, which can ultimately adjust the angle of the circuit board, thereby facilitating subsequent spot welding operations.

[0027] The clamping assembly includes a pair of accumulator covers 5, which are installed on both sides of the adjusting plate 3. A push rod 6 is inserted into the inside of each accumulator cover 5, and a clamping plate 7 is installed at the end of the push rod 6, clamping the circuit board. An insert rod 8 is installed on the push rod 6, and a slide rod 9 is installed at the end of the insert rod 8. A accumulator spring 11 is installed between the push rod 6 and the accumulator cover 5. A guide block 12 is installed on the adjusting plate 3, and a ramp 13 is installed on the guide block 12, corresponding to the slide rod 9. After welding, the operator needs to rotate the lead screw shaft 15 in the opposite direction to rotate the adjusting plate 3 to a horizontal position. During this process, the slide rod 9 on the adjusting plate 3 will slowly move downwards, eventually sliding along the ramp 13 of the guide block 12. Guided by the ramp 13, the slide rod 9 slides outwards, causing the insert rod 8 to slide synchronously. Simultaneously, the push rod 6 and the clamping plate 7 retract synchronously, unlocking the circuit board and facilitating its later removal.

[0028] like Figures 1 to 5 As shown in the specific embodiment, a base 2 is installed at the bottom of the mounting base 1, and an anti-slip pad is installed at the bottom of the base 2. The anti-slip pad increases the overall anti-slip performance of the equipment. A positioning plate 4 is installed at the bottom of the adjustment plate 3, and the positioning plate 4 overlaps under the circuit board. The positioning plate 4 can support the circuit board, so that the circuit board will not slide down, thus achieving the purpose of positioning the circuit board.

[0029] like Figures 1 to 5 As shown, further, a limiting plate 18 is installed on the side wall of the lead screw sleeve 17, and a limiting rod 19 is installed inside the limiting plate 18. The two ends of the limiting rod 19 are connected to the inner wall of the mounting base 1. A knob 16 is installed at the end of the lead screw shaft 15. The knob 16 can drive the lead screw shaft 15 to rotate. At this time, the lead screw shaft 15 will drive the lead screw sleeve 17 to slide horizontally, and the limiting plate 18 on the side wall of the lead screw sleeve 17 will slide along the limiting rod 19, thus achieving the purpose of limiting.

[0030] like Figures 1 to 5 As shown, furthermore, a pair of limiting guide rails 22 are installed at the bottom of the adjusting plate 3, and the end of the push rod 20 passes through the gap of the pair of limiting guide rails 22. A pair of protrusions 21 are installed at the end of the push rod 20, and the pair of protrusions 21 slide in the through grooves opened on the side walls of the corresponding limiting guide rails 22. When the lead screw sleeve 17 slides, the push rod 20 on the lead screw sleeve 17 slides between the pair of limiting guide rails 22, and the protrusions 21 on the side walls of the push rod 20 slide in the through grooves of the limiting guide rails 22, ultimately causing the position of the adjusting plate 3 to deflect.

[0031] like Figures 1 to 5As shown, further, a power storage plate 10 is slidably installed inside the power storage cover 5, and both ends of the power storage plate 10 are connected to the insertion rod 8 and the top rod 6 respectively. A power storage spring 11 is sleeved on the top rod 6, with one end of the power storage spring 11 engaged with the inner wall of the power storage cover 5 and the other end engaged with the power storage plate 10. When the slide rod 9 slides, it drives the insertion rod 8 and the power storage plate 10 to slide synchronously, thereby compressing the power storage spring 11. The power storage spring 11 facilitates subsequent reset. The thickness of the guide block 12 is greater than the length of the maximum stroke of the clamping plate 7. A notch 14 is provided on the guide block 12, and the position of the notch 14 is adapted to the position of the insertion rod 8.

[0032] The implementation principle of a multi-angle circuit board spot welding auxiliary frame is as follows:

[0033] When the angle of the circuit board on the adjusting plate 3 needs to be adjusted, the operator can first turn the knob 16, which will drive the lead screw shaft 15 to rotate. At this time, the lead screw shaft 15 will drive the lead screw sleeve 17 to slide horizontally. The limiting plate 18 on the side wall of the lead screw sleeve 17 slides along the limiting rod 19, which serves as a limiting purpose. When the lead screw sleeve 17 slides, the push rod 20 on the lead screw sleeve 17 slides between a pair of limiting guide rails 22, and the protrusion 21 on the side wall of the push rod 20 slides in the through groove of the limiting guide rail 22. Finally, the position of the adjusting plate 3 is deflected, and the adjusting plate 3 rotates around the mounting base 1. Finally, the angle of the circuit board can be adjusted, which facilitates the subsequent spot welding operation.

[0034] After welding is completed, the operator needs to rotate the lead screw shaft 15 in the opposite direction to rotate the adjusting plate 3 to a horizontal position. During this process, the slide rod 9 on the adjusting plate 3 will slowly move down and eventually slide along the ramp 13 of the guide block 12. Guided by the ramp 13, the slide rod 9 will slide outward. At this time, the insertion rod 8 slides in the notch 14 of the guide block 12. As the slide rod 9 slides, it drives the insertion rod 8 and the energy storage plate 10 to slide synchronously, thereby compressing the energy storage spring 11. The top rod 6 and the clamping plate 7 on the energy storage plate 10 retract synchronously, unlocking the circuit board and facilitating the disassembly of the circuit board later.
