Technical Field

[0001] This utility model relates to the field of welding auxiliary equipment technology, specifically to a circuit board welding auxiliary bracket. Background Technology

[0002] During the soldering process of printed circuit boards (PCBs), auxiliary tools are usually needed to fix the PCB in place so that operators can perform soldering operations stably and accurately. Currently available soldering auxiliary supports are often referred to as "third hands." Their structures are mostly relatively simple, generally including a counterweight base and several alligator clips connected by universal tubes.

[0003] However, existing circuit board welding auxiliary supports have shortcomings in actual use. When performing delicate welding operations for a long time, the operator's wrists need to be suspended in the air for a long time (especially when some users are recording teaching demonstration videos). The lack of effective support can easily lead to hand fatigue and tremors, affecting the welding teaching experience.

[0004] Therefore, how to design a circuit board welding auxiliary support that can stably hold the circuit board while improving the user experience of operators is an urgent problem to be solved in current circuit welding teaching aids. Utility Model Content

[0005] The purpose of this utility model is to provide a circuit board welding auxiliary support. This circuit board welding auxiliary support can stably hold the circuit board while providing wrist or arm support for the operator, reducing hand fatigue and tremors caused by long-term welding operations, improving the welding teaching demonstration experience, and meeting the needs of circuit welding teaching.

[0006] The technical solution adopted by this utility model to solve the above problems is: a circuit board welding auxiliary bracket, including a base and a clamping assembly, wherein the clamping assembly is fixedly disposed on the base, and a support component for supporting the wrist or arm is provided on the front side of the clamping assembly.

Detailed Implementation

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0023] Example:

[0024] See Figure 1 - Figure 6 This embodiment relates to a circuit board welding auxiliary bracket, which is specifically used to fix circuit boards of different sizes and provide wrist support and multi-functional auxiliary clamping for the operator during the welding process. Specifically, it includes: a base 1 and a clamping assembly 2. The clamping assembly 2 is fixedly mounted on the base 1. The front side of the clamping assembly 2 is provided with a support component 3 for supporting the wrist or arm. The clamping assembly 2 includes two sets of clamping units 21. The clamping unit 21 includes a base frame 211 and a base 22. The base 22 is elastically slidably connected to a clamping block 23 via a spring 231, and the base 22 is provided with a drive knob 24 for driving the clamping block 23 to move away from or closer to it. The support component 3 includes a long bracket 31 and two sets of support plates 32. The support plates 32 are slidably connected to the long bracket 31 via a slide block 33.

[0025] Specifically, in this embodiment, the operator should first place the base 1 stably on the workbench, and then fix the circuit board using the clamping assembly 2. Specifically, by turning the drive knob 24, the internal threaded structure pushes the clamping block 23 outward against the spring force of the spring 231, or retracts it inward under the spring force, thereby quickly adjusting the size of the clamping opening. After placing the circuit board between the two clamping blocks 23, rotate the knob again to stably fix the circuit board.

[0026] After the circuit board is fixed, the operator can perform soldering operations. During soldering, the operator holds the solder wire and soldering gun with their left and right hands respectively, and their arms or wrists can rest on the support plate 32 to reduce hand fatigue and tremors caused by prolonged soldering operations, thereby improving the soldering teaching demonstration experience and meeting the needs of circuit soldering teaching. In addition, the support plate 32 is also equipped with flexible pads so that the operator's wrists can be supported on the flexible pads during soldering. The support plate 32 can rotate horizontally and swing vertically relative to the slide 33 to adapt to the operator's hand soldering posture. At the same time, the support component 3 can adjust the distance between the two sets of support plates 32 by moving the slide 33 left and right relative to the long bracket 31 to adapt to the distance between the operator's wrists.

[0027] The clamping assembly 2 is used to fix the circuit board to be soldered, see [link / reference]. Figure 3 It includes two sets of symmetrically arranged clamping units 21. Each clamping unit 21 includes a base frame 211 and a base 22. The bottom of the base frame 211 is provided with two sets of connectors 2111, and the base 1 is provided with corresponding through holes 11. The connectors 2111 can be inserted into the through holes 11 to realize quick installation and removal of the clamping unit 21 and the base 1. The user can select to install the clamping unit 21 in different through holes 11 on the base 1 according to the size of the circuit board (length, width) to adjust the distance between the two.

[0028] In this embodiment, the base 1 is made of a high-density plastic material (such as bakelite) with a certain weight to ensure the overall stability of the support. A foot pad 12 is provided below the base 1, and a stud 121 threadedly connected to the base 1 is provided at the upper end of the foot pad 12. The foot pad 12 is made of non-slip rubber material, which can effectively prevent the support from sliding on a smooth work surface.

[0029] See Figure 4 In this embodiment, the long support bracket 31 has elongated slots 312 at both ends. The studs 121 of the two foot pads 12 at the front of the base 1 pass through these two slots 312 and are tightened from above using nut 34. The long support bracket 31 has a sliding groove 311, and each set of support plates 32 is slidably mounted on the sliding groove 311 via a sliding seat 33. The sliding seat 33 consists of a slider 331 and a damping rotating seat 332. The slider 331 cooperates with the sliding groove 311, allowing the support plate 32 to slide freely left and right to adjust the distance between the two wrists. The damping rotating seat 332 is fixed on the slider 331, and its upper end is hinged to the bottom (damping) of the support plate 32 via a pin. The damping design (achieved by friction formed by rubber in the connecting pair) gives the support plate 32 a certain damping feel when rotating (swinging) to adapt to the operator's hand movements.

[0030] To further enhance the practicality of this device, several auxiliary functions are integrated. A column 2112 is installed at one end of the left base frame 211, and a wire guide 5 is installed at the top of the column 2112. The wire guide 5 has gaps of varying widths to accommodate solder wires of different diameters. By inserting solder wires of different diameters into the gaps of varying widths, the solder wires remain straight when pulled out, making them easy to access. In this embodiment, a corresponding column 2112 is also installed on the right base frame 211, which can be used for subsequent development of corresponding accessories (such as mounting lights, fans, etc.) to expand functionality.

[0031] In this embodiment, the clamping assembly 2 further includes two sets of movable grippers 4, see [link to previous embodiment]. Figure 5 The movable gripper 4 includes a universal tube 42 (which can be a bamboo-joint universal tube 42 or a metal universal tube 42) and a clamp 41 (which can be an alligator clip). One end of the universal tube 42 is provided with a threaded sleeve 421 that is screwed onto the studs 121 of the foot pads 12, which can be directly screwed onto any exposed stud 121 of the foot pads 12, making installation very convenient. The other end of the universal tube 42 is provided with a sleeve 422 that fits onto one side of the pressing part of the clamp 41, and a locking member 423 for fixing the pressing part is screwed onto the sleeve 422, so that one side of the pressing part of the clamp 41 can be inserted into the sleeve 422 and locked by the locking member 423 (which can be a hand screw) on the side of the sleeve 422. The universal tube 42 can be bent and deformed at will, so that the clamp 41 can clamp circuit boards, wires, components, etc. from any angle, acting as a "third hand" during soldering.

[0032] In addition, in this embodiment, see Figure 6 A connecting seat 6 is provided on the rear side of the clamping assembly 2. A connecting rod 61 is vertically arranged on the connecting seat 6. A connecting frame 62 is slidably and lockably connected to the connecting rod 61. A magnifying glass 63 is ball-jointed to the end of the connecting frame 62. The connecting frame 62 can slide up and down along the connecting rod 61, and the magnifying glass 63 can rotate around the ball-joint point and be fixed by a locking knob. When fine welding is required, the magnifying glass 63 can be adjusted to a suitable height and angle to magnify and observe the weld point, effectively improving welding accuracy and protecting eyesight.

[0033] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
