[0002] Adjustable circuit board welding refers to a welding method that uses a series of adjustable welding tools and equipment, as well as flexible and variable welding process parameters, to adapt to the welding needs of different types and specifications of circuit boards in order to achieve high-quality welding results.

[0003] However, in electronic circuit board soldering operations, adjustable circuit board soldering fixtures are crucial, but in practical applications, their shortcomings are obvious. Operators often need to manually and frequently adjust their height and angle. This process is tedious and complicated, requiring careful turning of knobs or levers, which consumes a lot of time and energy, seriously reduces the ease of adjustment, and may also affect the soldering quality due to improper adjustment, resulting in low soldering efficiency and failing to meet the requirements of high-efficiency production.

[0004] To address the aforementioned issues, this application proposes an adjustable circuit board welding positioning fixture. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides an adjustable circuit board welding positioning fixture, which improves the ease of adjustment of the circuit board welding fixture.

[0024] Example

[0025] Please see Figure 1-6 The present invention provides the following technical solution: an adjustable circuit board welding positioning fixture, including a support plate 1, a slot frame 2, a controller 3 and a gear brake motor 13 respectively arranged on the upper part of the support plate 1, an electric telescopic rod 7 fixedly connected to the inner bottom wall of the slot frame 2, a telescopic column 8 slidably connected inside the slot frame 2, the bottom surface of the telescopic column 8 being fixedly connected to the telescopic end of the electric telescopic rod 7, a rotating collar 9 being fixedly connected to the upper surface of the telescopic column 8, a serrated ring 10 being fixedly connected to the outer surface of the inner ring of the rotating collar 9, the outer surface of the serrated ring 10 meshing with the power output end of the gear brake motor 13, a support frame 14 being fixedly connected to the upper surface of the inner ring of the rotating collar 9, and two sets of electric push rods 15 being arranged inside the support frame 14, with a clamping plate 16 fixedly connected to the telescopic end of each electric push rod 15;

[0026] In this embodiment, the inner ring of the rotating collar 9 rotates inside the outer ring. At the same time, by fixing the outer ring, the inner ring can rotate. The power output end of the gear brake motor 13 is fixed with a gear ring, which can drive the sawtooth ring 10 to rotate.

[0027] Specifically, two sets of fixing pins 5 are provided on the upper part of the support plate 1. The bottom end of each fixing pin 5 passes through the support plate 1 and extends to the lower part of the support plate 1. In this embodiment, the support plate 1 can be penetrated and fixed in a suitable device through the fixing pins 5, so that the support plate 1 can be fixed for use.

[0028] Specifically, a support platform 4 is fixedly connected to the upper surface of the support plate 1. The upper surface of the support platform 4 is fixedly connected to the bottom surface of the controller 3. In this embodiment, the controller 3 can be fixed to the support plate 1 through the support platform 4. At the same time, the controller 3 refers to the master control device that controls the starting, speed regulation, braking and reversing of the motor by changing the wiring of the main circuit or control circuit and changing the resistance value in the circuit according to a predetermined sequence.

[0029] Specifically, a fixing ring 6 is fixedly connected to the bottom surface of the slot frame 2. The bottom surface of the fixing ring 6 is fixedly connected to the upper surface of the support plate 1. In this embodiment, the slot frame 2 can be fixed to the support plate 1 through the fixing ring 6, so that the slot frame 2 can be used stably.

[0030] Specifically, a support base 12 is fixedly connected to the outer surface of the outer ring of the rotating collar 9. The front of the support base 12 is fixedly connected to the back of the gear brake motor 13. In this embodiment, the gear brake motor 13 can be fixedly used through the support base 12. At the same time, the gear brake motor 13 is a motor with braking function, which is usually used in applications that require rapid stopping or precise position control.

[0031] Specifically, a protective shell 11 is fixedly connected to the outer surface of the support base 12. The protective shell 11 is sleeved on the outside of the gear brake motor 13. In this embodiment, the gear brake motor 13 can be protected inside by the protective shell 11, and the gear brake motor 13 can be cooled by the opening of the protective shell 11.

[0032] Specifically, each set of electric push rods 15 is fixedly connected to a connecting plate 17 at one end away from each other, and the side of each connecting plate 17 that is away from each other is fixedly connected to the inner wall of the support frame 14. In this embodiment, the electric push rods 15 can be fixed to the support frame 14 through the connecting plate 17, so that the electric push rods 15 can extend and retract stably.

[0033] Specifically, each set of clamping plates 16 has a protective pad 18 fixedly connected to one side of each other. Each protective pad 18 must be made of soft rubber. In this embodiment, the soft material of the protective pad 18 itself can protect the surface of the circuit board when the clamping plates 16 are clamped and positioned.

[0034] The working principle and usage process of this utility model are as follows: First, connect the electric telescopic rod 7, gear brake motor 13, electric push rod 15, and controller 3 to the power supply. Simultaneously, connect the electric telescopic rod 7, gear brake motor 13, and electric push rod 15 to the controller 3 via wires. Fix the support plate 1 to the appropriate position using the fixing pin 5. Then, place the circuit board to be welded between each set of protective pads 18. Simultaneously, the controller 3 opens and extends the electric push rod 15, which moves the clamping plate 16. The movement of the clamping plate 16 moves each set of protective pads 18 closer together, clamping and positioning the circuit board within the support frame 14. When the circuit board is positioned and welding requires angle adjustment, the controller 3 starts the gear brake motor 13 to rotate forward or backward. Simultaneously, the rotation of the gear brake motor 13 moves the sawtooth ring 10 to follow. The rotation of the sawtooth ring 10 drives the inner ring of the rotating collar 9 to rotate. Simultaneously, the rotation of the rotating collar 9 drives the support frame 14 to adjust the welding angle with the circuit board. When the angle adjustment is completed and the height adjustment is required, the controller 3 opens and extends the electric telescopic rod 7. The extension and retraction of the electric telescopic rod 7 drives the telescopic column 8 to slide up and down in the slot frame 2. Simultaneously, the sliding of the telescopic column 8 drives the rotating collar 9, gear brake motor 13, and support frame 14 to move up and down with the circuit board, thereby adjusting the height of the circuit board to the required position. After the circuit board is welded, the controller 3 opens and retracts the electric push rod 15. The retraction of the electric push rod 15 drives the clamping plate 16 and protective pad 18 to move, and simultaneously releases the clamping plate 16 and protective pad 18 from the circuit board, further improving the convenience of using the adjustable circuit board welding positioning fixture.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
