[0002] Wave soldering is a process in which molten solder is sprayed into a designed wave shape using an electric or electromagnetic pump. A printed circuit board (PCB) pre-loaded with components passes through this wave, achieving mechanical and electrical connections between the component leads and the PCB pads. During wave soldering, the soldering fixture plays a crucial role; it holds the PCB in place, ensuring stability and thus guaranteeing accurate and consistent soldering.
[0003] Most existing wave soldering fixtures are of fixed size and can only be used for circuit boards of specific specifications. With the diversification of electronic products, the size and specifications of circuit boards are increasing, requiring corresponding soldering fixtures for different sizes of circuit boards. This not only increases the procurement cost of fixtures, but also the frequent replacement of fixtures can easily lead to positioning errors and affect the soldering quality. At the same time, the fixing plates in existing fixtures are mostly made of rigid materials, which can easily damage the surface of the board if they come into direct contact with it, resulting in certain inconveniences in use.

[0010] A further improvement of this utility model is that: a second screw is fixedly connected to one end of the second motor shaft, and a slide rail is fixedly connected to the top of the support member.
[0011] A further improvement of the present invention is that the fixing mechanism includes a second driving block, a fixing member is fixedly connected to the bottom of the second driving block, and a cylinder is fixedly connected to the surface of the fixing member.

[0023] The present invention will be further described in detail below with reference to embodiments:
[0024] Example 1
[0025] like Figure 1-6 As shown, this utility model provides an adjustable-size wave soldering fixture, including a support mechanism, an adjustment mechanism on the surface of the support mechanism, and a fixing mechanism on the surface of the adjustment mechanism. The support mechanism includes a support plate 11, a mounting component 12 fixedly connected to the bottom of the support plate 11, a mounting plate 13 fixedly connected to the bottom of the support plate 11, a mounting sleeve 14 fixedly connected to the top of the support plate 11, a spring 15 provided at the bottom of the inner cavity of the mounting sleeve 14, a top rod 16 connected to one end of the spring 15, a support block 17 fixedly connected to the top of the top rod 16, a rubber block 18 fixedly connected to the top of the support block 17, and a wave soldering plate 19 provided on the surface of the rubber block 18.
[0026] In this embodiment, the L-shaped fixing plate 34 is moved downward by the cylinder 33, applying downward pressure to the wave soldering plate 19 and pressing it against the surface of the rubber block 35. Under the pressure, the push rod 16 compresses the spring 15, causing the spring 15, rubber block 18, and rubber pad 35 to contract and deform. Under the action of the reaction force, an upward thrust is applied to the wave soldering plate 19, thereby achieving fixation. Furthermore, the fixation method in which multiple rubber blocks 16 and rubber pads 35 are in direct contact with the plate can also prevent damage to the wave soldering plate 19 during fixation. During the welding process, the vibration generated will cause the spring 15 to further contract and the rubber to stretch, maintaining a good fixation effect while avoiding excessive impact on the wave soldering plate 19, making it easier to use.
[0027] Example 2
[0028] like Figure 1-6As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the adjustment mechanism includes a first motor 21, the surface of the first motor 21 is fixedly connected to the surface of the mounting plate 13, one end of the shaft of the first motor 21 is fixedly connected to a first screw 22, the surface of the first screw 22 is threadedly connected to a first drive block 23, the inside of the first drive block 23 is slidably connected to a slide rod 24, both ends of the slide rod 24 are fixedly connected to the surface of the mounting plate 13, the top of the first drive block 23 is fixedly connected to a support member 25, the top of the support member 25 is fixedly connected to a second motor 26, one end of the shaft of the second motor 26 is fixedly connected to a second screw 27, and the top of the support member 25 is fixedly connected to a slide rail 28.
[0029] In this embodiment, when the wave soldering plate 19 is being welded, it is placed on the surface of the support mechanism. Then, the first motor 21 and the second motor 26 are started, causing the first screw 22 and the second screw 27, which have bidirectional threads on their surfaces, to rotate. Under the action of the rotation of the first screw 22, the first drive block 23 slides along the slide bar 24 to adjust the left and right position of the fixing mechanism. Under the action of the rotation of the second screw 27, the second drive block 31 slides along the slide rail 28 to adjust the front and rear position of the fixing mechanism.
[0030] Example 3
[0031] like Figure 1-6 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the fixing mechanism includes a second driving block 31, a fixing member 32 is fixedly connected to the bottom of the second driving block 31, a cylinder 33 is fixedly connected to the surface of the fixing member 32, an L-shaped pressure plate 34 is fixedly connected to the output end of the cylinder 33, a rubber pad 35 is fixedly connected to the bottom of the L-shaped pressure plate 34, the interior of the second driving block 31 is threadedly connected to the surface of the second screw 27, and both ends of the second driving block 31 are slidably connected to the surface of the slide rail 28.
[0032] In this embodiment, the L-shaped fixing plate 34 is moved downward by the cylinder 33, which applies downward pressure to the wave soldering plate 19 and presses it onto the surface of the rubber block 35. Under the pressure, the push rod 16 compresses the spring 15, causing the spring 15, the rubber block 18, and the rubber pad 35 to contract and deform. Under the action of the reaction force, an upward thrust is applied to the wave soldering plate 19, thereby achieving fixation.
[0033] The working principle of this adjustable-size wave soldering fixture will be explained in detail below.
[0034] like Figure 1-6As shown, when welding the wave soldering plate 19, it is placed on the surface of the support mechanism. Then, the first motor 21 and the second motor 26 are started, causing the first screw 22 and the second screw 27, which have bidirectional threads on their surfaces, to rotate. Under the action of the rotation of the first screw 22, the first drive block 23 slides along the slide bar 24 to adjust the left and right position of the fixing mechanism. Under the action of the rotation of the second screw 27, the second drive block 31 slides along the slide rail 28 to adjust the front and back position of the fixing mechanism. After adjusting to the appropriate position, the cylinder 33 is started. Under the action of the cylinder 33, the L-shaped fixing plate 34 moves down to apply the wave soldering plate 19. Applying downward pressure presses it onto the surface of the rubber block 35. Under this pressure, the push rod 16 compresses the spring 15, causing the spring 15, rubber block 18, and rubber pad 35 to contract and deform. Under the action of the reaction force, an upward thrust is applied to the wave-welded plate 19, thereby achieving fixation. Furthermore, the fixation method, in which multiple rubber blocks 16 and rubber pads 35 are in direct contact with the plate, also avoids damage to the wave-welded plate 19 during fixation. During the welding process, the vibration generated will cause the spring 15 to further contract and the rubber to stretch, maintaining a good fixation effect while preventing the wave-welded plate 19 from being subjected to excessive impact, making it easier to use.
[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
