DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Example
[0025] This embodiment is intended to promote the solution of the problem that the existing single-sided circuit board assembly needs to use a clamp to hold up the circuit board during the welding process, but not all circuit boards are normal rectangular shapes, so it is difficult to clamp the circuit board. Please refer to Figure 1-6 A single-sided circuit board assembly includes an operating table 1. The operating table 1 is the basis of the entire assembly and provides support for the installation and operation of other components. A clamping assembly 3 for clamping a circuit board 2 is fixedly installed above the operating table 1. The clamping assembly 3 is used to ensure that there is no displacement during the welding process of the circuit board 2 to prevent unstable factors during the processing process. A sliding assembly 4 is connected to one side of the clamping assembly 3. The function of the sliding assembly 4 is to make the clamping assembly 3 have adjustable mobility to adapt to circuit boards 2 of different sizes or shapes. A control assembly 5 for controlling the clamping assembly 3 is provided on one side of the sliding assembly 4. The control assembly 5 is fixedly installed on the operating table 1. A fixing assembly 6 is provided on the control assembly 5, and its function is to provide precise control of the movement of the clamping assembly 3 to ensure accurate positioning and stable clamping of the circuit board 2. Through the synergistic effect of the sliding assembly 4 and the control assembly 5, the design can achieve highly precise clamping and control of the circuit board 2 to ensure the stability of the circuit board 2 during welding.
[0026] In this embodiment: the sliding assembly 4 includes a hydraulic rod 41 fixedly mounted on the operating table 1, which enables the clamping assembly 3 to adjust the clamping force as needed to adapt to circuit boards 2 of different sizes. One end of the hydraulic rod 41 is fixedly connected to a sliding fixing plate 42, and the sliding fixing plate 42 is slidably connected to a sliding rail 43. The sliding rail 43 is fixedly mounted on the operating table 1, which helps to ensure the stability of the clamping assembly 3 during movement, thereby protecting the circuit board 2 from unnecessary vibration or impact. Through the flexibility and adjustability of the sliding assembly 4, the operator can more easily adapt to the manufacturing requirements of different circuit boards 2, thereby improving production efficiency.
[0027] In this embodiment: the clamping assembly 3 includes a fixed mounting plate 31 fixedly connected to the operating table 1, and the fixed mounting plate 31 and the sliding mounting plate are fixedly connected with a pressure oil tank 32. One side of the pressure oil tank 32 is fixedly connected with an oil pipe 33. The oil pipe 33 passes through the fixed mounting plate 31 and the sliding mounting plate. The other side of the pressure oil tank 32 is connected with multiple clamping rods 34. The design of multiple clamping rods 34 allows the circuit board 2 to be clamped at multiple points, which helps to disperse the clamping force, reduce the pressure on the circuit board 2 due to clamping, and improve the stability and uniformity of clamping. The clamping rods 34 can be automatically adjusted according to the size and shape of the circuit board 2 to ensure that the circuit board 2 is firmly fixed in the clamping assembly 3.
[0028] In this embodiment: a telescopic rod 35 is slidably connected inside the clamping rod 34, and one end of the telescopic rod 35 is fixedly connected with an elastic spring 36, which is located inside the clamping rod 34. The presence of the elastic spring 36 provides a certain elasticity in the clamping rod 34, which helps to adapt to circuit boards 2 of different sizes and shapes. The sliding connection of the telescopic rod 35 enables the clamping system to adjust the length of the clamping rod 34 to automatically adapt to changes in the circuit board 2. A clamping block 37 is fixedly installed on the other end of the telescopic rod 35, and a soft clamping block 38 for contacting the circuit board 2 is fixedly installed on the clamping block 37. Such a design enables the clamping system to provide clamping force through the contact between the soft clamping block 38 and the circuit board 2. At the same time, the design of the soft clamping block 38 can prevent damage to the circuit board 2. A groove 39 for clamping the circuit board 2 is provided on the soft clamping block 38. The presence of the groove 39 helps to ensure that the circuit board 2 is evenly and stably supported during the clamping process to prevent the circuit board 2 from sliding or moving.
[0029] In this embodiment: the control component 5 includes an oil storage tank 51 fixedly connected to the oil delivery pipe 33, a control rod 52 is slidably connected inside the oil storage tank 51, one end of the control rod 52 is fixedly connected to a movable block 53, the movable block 53 is slidably connected to the inner wall of the oil storage tank 51, and a sealing ring 54 for increasing the sealing performance is fixedly installed on the movable block 53. The presence of the sealing ring 54 improves the sealing performance of the hydraulic system, helps to prevent liquid leakage, and maintains a clean operating environment. The hydraulic system provides a smooth hydraulic pressure, which helps to ensure the stable movement of the clamping component 3, so that the circuit board 2 will not be affected by unnecessary shock or vibration during the clamping process.
[0030] In this embodiment: a limiting groove 55 for limiting the position of the movable block 53 is opened on the inner wall of the oil storage tank 51. The existence of the limiting groove 55 can effectively limit the sliding range of the movable block 53 in the oil storage tank 51. By limiting the movable block 53, the oil in the oil storage tank 51 can be controlled, thereby achieving the fixation of the clamping rod 34.
[0031] In this embodiment: the fixed component 6 includes a fixed rod 61 installed in the control rod 52, the fixed rod 61 is slidably connected to the inside of the control rod 52, a resistance block 62 is fixedly installed at one end of the control rod 52, and both sides of the resistance block 62 have inclined surfaces 63, and both sides of one end of the resistance block 62 are in resistance with a force rod 64, the force rod 64 is located in the movable block 53 and is slidably connected to the movable block 53, a steel spring 65 is fixedly connected to the resistance block 62, and one end of the steel spring 65 is fixedly connected to the inside of the control rod 52. Through the design of the fixed component 6, the movable block 53 can be fixed at a required position in the oil storage tank 51.
[0032] In this embodiment: one end of the force-bearing rod 64 is fixedly connected to a spring 66. The existence of the spring 66 enables the force-bearing rod 64 to slide into the movable block 53 after losing resistance, so that the force-bearing rod 64 is separated from the limiting groove 55. One end of the spring 66 is fixedly connected to the movable block 53. A sealing gasket 67 for increasing the sealing performance is installed at the contact point of the movable block 53 with the force-bearing rod 64. The design of the sealing gasket 67 can prevent oil from entering the movable block 53. One end of the force-bearing rod 64 is slidably connected to the limiting groove 55.
[0033] Working principle: first, place one side of the circuit board 2 into the groove 39, then start the hydraulic rod 41 to make the clamping block 37 on the clamping rod 34 clamp the circuit board 2 to form an initial fixation, then pull up the fixing rod 61 to make the force-bearing rod 64 break away from the fixation of the limiting groove 55, then drive the telescopic rod 35 to slide under the action of the elastic spring 36, so that the extended length of the telescopic rod 35 can adapt to the shape of the circuit board 2, then release the pull on the fixing rod 61, and under the action of the steel spring 65, the interference block 62 on the fixing rod 61 is in conflict with the force-bearing rod 64 on both sides, and at the same time, under the interference between the inclined surface 63 and the force-bearing rod 64, the force-bearing rod 64 slides to both sides, so that the force-bearing rod 64 is inserted into the limiting groove 55, thereby fixing the movable block 53.
[0034] After the movable block 53 is fixed, the oil in the oil storage tank 51 will stop flowing. By stopping the flow of oil, the oil in the pressure oil tank 32 and the clamping rod 34 will also stop flowing, making the interior into a vacuum state, so that the telescopic rod 35 stops sliding in the clamping rod 34, thereby achieving fixed clamping of the circuit board 2. The different lengths of the telescopic rods 35 can adapt to circuit boards 2 of various specifications.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
