However, when welding, the hand needs to hold it. If the holding angle is incorrect, it will cause the situation of false soldering. Therefore, a spring fixture for circuit boards is needed to solve the problem in the existing technology that when welding, the hand needs to hold it, and if the holding angle is incorrect, it will cause the situation of false soldering.

[0021] The following further describes the present utility model in conjunction with embodiments.

[0022] In order to make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings of the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the described embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0023] The following embodiments are used to illustrate the present utility model, but cannot be used to limit the protection scope of the present utility model. The conditions in the embodiments can be further adjusted according to specific conditions. Any simple improvement of the method of the present utility model under the premise of the concept of the present utility model belongs to the scope of protection required by the present utility model.

[0024] Embodiment

[0025] During the existing welding process, the hand needs to be supported. If the support angle is incorrect, it will cause the problem of false soldering.

[0026] For this reason, please refer to Figures 1-5 , the present utility model provides a circuit board spring fixture, including a placing table 1. Above the placing table 1, there is a vertical rod 21 fixedly connected thereto. A universal flexible shaft 22 for adjusting the position of the fixture is fixedly connected to the vertical rod 21. The other end of the universal flexible shaft 22 is provided with a clamping assembly 3 for fixing the spring.

[0027] The clamping assembly 3 includes a connecting plate 31 fixedly installed at the other end of the universal flexible shaft 22. The connecting plate 31 is designed by combining a horizontal plate and a circular plate. A plurality of clamping plates 32 arranged in a circular array are slidably connected to the connecting plate 31. Vertical rods 33 are fixedly installed at the tops of the clamping plates 32. The same turntable 34 is slidably connected to the outside of the vertical rods 33. Arc-shaped grooves matching the vertical rods 33 are provided on the turntable 34.

[0028] An inclined side ring 23 is fixedly installed on the outside of the vertical rod 21. The side ring 23 is in the shape of a frustum of a cone, and an inverted horn-shaped slot is provided inside. Through the side ring 23, the user can directly place the soldering pen on the device, which is convenient for the next welding use.

[0029] The positioning rod 35 is connected to the inner thread of the turntable 34. A thread groove matching the positioning rod 35 is provided at the center point of the turntable 34. The bottom end of the positioning rod 35 is fixedly connected to the top end of the connecting plate 31. When the user uses the spring fixture of this circuit board to install the switch spring, first place the circuit board on the placement table 1 of the fixture. After placing it, then adjust the position of the quick-adjustment clamping plate 32 of the connecting plate 31 through the universal flexible shaft 22. After adjustment, place the spring upright. After placing it, then turn the turntable 34 clockwise. The turntable 34 is provided with an arc-shaped groove. When the turntable 34 is turned clockwise, multiple clamping plates 32 will move inward simultaneously, so as to quickly clamp the upright spring. After clamping, adjust the position of the connecting plate 31 through the universal flexible shaft 22 and place it at the welding position to be welded. After placing it, fix it through the universal flexible shaft 22. After positioning, the user can hold the solder wire in one hand and the soldering pen in the other hand to perform the soldering work. This avoids the problem that when welding is carried out in the existing situation, the hand needs to be supported. If the support angle is incorrect, it will cause the problem of false soldering, thereby improving the stability of the device during use.

[0030] Furthermore, as Figure 2 shown, it is specifically worth noting that in order to facilitate the clamping of some cylindrical springs, the vertical cross-section of the clamping plate 32 is set as an inverted F shape. The clamping plate 32 adopts an inverted F-shaped design. In this way, for some cylindrical springs, the top loop can be directly inserted and clamped to fix it.

[0031] Furthermore, as Figure 3 shown, it is specifically worth noting that in order to clamp some inverted frustum-shaped springs, the clamping plates 32 are all designed as arc-shaped plates. Two inclined positioning blocks 4 are fixedly arranged on the outer sides of the clamping plates 32. The design of the clamping plate 32 combined with the two inclined positioning blocks 4 can, when welding some inverted frustum-shaped springs, insert and clamp and position the large loop at the top of the spring. Compared with the inverted F-shaped design, it is more portable when clamping, thereby improving the applicability of the device during use.

[0032] Furthermore, as Figures 4-5As shown, it is worth specifically explaining that in order to facilitate the quick clamping of the spring, a positioning rod 35 is fixedly connected inside the turntable 34. The positioning rod 35 is rotatably connected to the connecting plate 31. A side plate 5 with an L-shaped vertical cross-section is arranged outside the turntable 34. The side plate 5 is fixedly connected to the connecting plate 31. A micro motor 51 is fixedly installed at the top of the side plate 5. The output shaft of the micro motor 51 extends to the bottom of the side plate 5 and is connected to the top of the positioning rod 35. Here, compared with the above part, the point-moving method of the micro motor 51 is adopted. When the spring needs to be clamped, the user can simply control the micro motor 51, which effectively improves the stability of the device during use.

[0033] The positioning rod 35 includes a transmission rod 6 fixedly installed on the output shaft of the micro motor 51. A transmission shaft 61 rotatably connected to the connecting plate 31 is arranged outside the transmission rod 6. A rubber block 62 is fixedly installed outside the transmission shaft 61. A cavity is opened inside the transmission shaft 61. Two symmetrically arranged convex blocks 63 are fixedly installed on the inner top wall of the cavity. When the micro motor 51 rotates, it may exceed the predetermined range. To ensure the normal use of the micro motor 51, the positioning rod 35 is split into the combination of the transmission shaft 61 and the transmission rod 6. The connection between the two is locked by the convex block 63 and the rubber block 62. Since the welded spring is small and light in weight, the positioning after clamping the spring can be achieved by the locking of the convex block 63 and the rubber block 62, which effectively ensures the normal use of the micro motor 51 and avoids the damage caused by the micro motor 51 exceeding the predetermined range.
