Description

Technical Field

[0001] The utility model relates to the technical field of circuit board chip mounting, and specifically, to an auxiliary tooling for circuit board chip mounting. Background Art

[0002] Circuit board chip mounting refers to the abbreviation of a series of process flows carried out on the basis of a printed circuit board. The basic process components include: screen printing or dispensing, chip mounting and curing, reflow soldering, cleaning, inspection, and repair. The surface mounting technology of electronic circuits is called surface mounting or surface mounting technology. It is a circuit assembly technology that mounts surface-mounted components without pins or short leads on the surface of a printed circuit board or other substrates and is soldered and assembled by methods such as reflow soldering or dip soldering. During the chip mounting process of the circuit board, an auxiliary tooling is used to limit and fix the circuit board to facilitate better operation by workers. However, when the existing auxiliary tooling is in use, the circuit board cannot be limited and fixed when placed on the processing panel, so that the circuit board is prone to shift when the worker performs chip soldering on the circuit board, which will affect the chip mounting effect. There are certain inconveniences in use and there is room for improvement.

[0003] The prior art, such as the utility model with the authorization announcement number CN219555274U, facilitates the limiting and fixing of the circuit board when placed on the processing panel.

By adopting the L-shaped clamping plates, the clamping and fixing of the two sides and the upper side of the circuit board are realized, which is convenient for subsequent chip mounting.

[0008] As a further limitation of this technical solution, the symmetrically arranged vertical mounting rods are respectively fixedly connected to symmetrically arranged fixed shafts. The lower end of each connecting rod is rotatably connected to each fixed shaft, the upper end of each connecting rod is rotatably connected to a U-shaped shaft, each U-shaped shaft is connected to a mounting seat, and the mounting seat is fixedly connected to a support plate. By adopting the support plate and the connecting rod in a rotational connection, the synchronous movement of the support plate and the L-shaped clamping plate is realized, and the fixing of the circuit board is achieved.

[0009] As a further limitation of this technical solution, a screw rod is connected to the inside of the chute by means of a bearing, and the two sections of reverse threads of the screw rod are respectively threadedly connected to the corresponding sliders. By adopting the screw rod, the L-shaped clamping plates on both sides are enabled to approach or move away from each other.

[0010] As a further limitation of this technical solution, the chute is fixedly connected to a motor, and the output shaft of the motor is fixedly connected to the screw rod. By adopting the motor, power is provided for the movement of the L-shaped clamping plate and the support plate.

[0011] As a further limitation of this technical solution, the workbench is fixedly connected to a controller, the controller is fixedly connected to a switch, and the switch and the motor are respectively electrically connected to the controller.

[0012] As a further limitation of this technical solution, a pressure sensor is installed on the lower side of the horizontal plate of the L-shaped clamping plate, and the pressure sensor is electrically connected to the controller. When the pressure sensor senses a pressure signal, the controller automatically shuts down the motor.

[0013] As a further limitation of this technical solution, the surface of the L-shaped clamping plate is coated with rubber to avoid damaging the circuit board when clamping the circuit board.

[0014] Compared with the related art, a circuit board soldering auxiliary tooling provided by the present utility model has the following

[0015] Beneficial effects:
