Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and in particular to a spraying device for anti-splashing circuit board processing. Background Technology

[0002] Currently, both traditional manual spraying and most automatic spraying equipment on the market are widely used in the electronics manufacturing industry for circuit board surface treatment. However, these traditional spraying methods and technologies face a series of challenges. Unstable spraying quality is a common phenomenon, especially when dealing with circuit boards with complex geometries. For the demand for high-efficiency mass production, existing spraying technologies often cannot provide sufficient support, resulting in low production efficiency. In response to the above problems, some improvement measures and technological attempts have been made in the market. Some manufacturers have increased the number of nozzles to improve the uniformity of spraying. Although this method can improve the spraying effect to a certain extent, it does not fundamentally solve the problem of spraying complex-shaped circuit boards. On the contrary, it may make maintenance more difficult due to the increased complexity of the equipment structure. Some companies have tried to improve spraying efficiency and quality by optimizing the spraying trajectory algorithm, but this depends on advanced programming skills, which is not conducive to popularization and application.

[0003] A search revealed Chinese Patent Publication No. CN112427191A, which discloses a spraying device for circuit board processing. The device includes a base, a support mechanism on the upper surface of the base, a lifting mechanism on the support mechanism, a circuit board fixing mechanism at the lower end of the lifting mechanism, a transmission mechanism on one side of the lifting mechanism, and a spraying mechanism at the upper end of the lifting mechanism. The beneficial effects of this invention are: The circuit board processing spraying device, by setting up a base, support mechanism, lifting mechanism, circuit board fixing mechanism, transmission mechanism, and spraying mechanism, allows for the activation of a dual-head drive motor during use. The dual-head drive motor drives the first and second fixing seats closer together, causing the spray nozzle to enter the placement slot and abut against the circuit board. This facilitates spraying the circuit board while preventing paint from flying everywhere. However, the above structure does not provide positioning and fixing for the circuit board, which can lead to a decrease in spraying quality and uneven coating. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a splash-proof spraying device for circuit board processing, which aims to improve the problem that the lack of positioning and fixing of the circuit board in the prior art leads to a decrease in spraying quality and uneven coating.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a splash-proof spraying device for circuit board processing, comprising a housing, a base plate fixedly connected to the inner wall of the housing, a motor fixedly connected to the bottom surface of the inner wall of the housing, a turntable fixedly connected to the output end of the motor, a connecting rod rotatably connected to the outer edge of the motor, a sliding rod rotatably connected to the other end of the connecting rod, a right-angle block fixedly connected to the outer wall of the sliding rod, a plurality of limiting posts fixedly connected to the top surface of the right-angle block, a longitudinal slide rail fixedly connected to the top of the inner wall of the housing, a sliding module slidably connected to the outer wall of the longitudinal slide rail, a transverse slide rail fixedly connected between adjacent sliding modules, a mounting block slidably connected to the outer wall of the transverse slide rail, and a splash-proof mechanism provided at the bottom of the mounting block, the splash-proof mechanism being used for spraying.

A base plate is firmly fixed to the inner wall of the outer shell, playing a crucial role in supporting and stabilizing other components within the device. A motor is fixedly connected to the bottom surface of the inner wall of the outer shell, acting as the power source. A turntable is firmly fixedly connected to the motor's output end. When the motor starts and runs, the turntable rotates in a circular motion. As the motor rotates, the circular motion of the turntable is converted into the reciprocating linear motion of a sliding rod through the transmission action of a connecting rod. A straight... The corner blocks and right-angle blocks have multiple limiting posts neatly fixedly connected to their top surfaces. These limiting posts position, guide, and limit the range of motion of the circuit board during the operation of the device. The top of the inner wall of the outer shell is also fixedly connected to the longitudinal slide rail. The outer wall of the longitudinal slide rail can smoothly slide and connect with the sliding module, allowing the sliding module to slide flexibly along the longitudinal direction of the slide rail. The adjacent sliding modules are fixedly connected to the transverse slide rail, and the outer wall of the transverse slide rail is slidably connected to the mounting block. The mounting block can then slide left and right on the transverse slide rail. Furthermore, through the sliding of the sliding module on the longitudinal slide rail, the mounting block can move freely in a two-dimensional plane.

On the bottom surface of the telescopic rod, the nozzle is fixedly connected with the same firm connection method. The nozzle ensures that the liquid forms a uniform and stable spray effect when sprayed. At the bottom of the outer wall of the telescopic rod, the mounting platform is firmly fixedly connected. The mounting platform is a disc with a certain thickness and strength, and the outer wall is machined with a standard thread structure. The thread structure is perfectly matched with the thread on the outer wall of the lead screw, and the two can achieve a tight threaded connection. The lead screw is a slender metal rod, and a hexagonal prism is fixedly connected to the middle of the outer wall. The hexagonal prism facilitates the rotation of the lead screw using a special tool. At the bottom of the lead screw, a baffle is fixedly connected. The baffle is of moderate size and conical shape, which can effectively block the splashing of liquid and play a key protective role.

[0013] As a further description of the above technical solution:

[0014] A sliding door is slidably connected between adjacent door frames and door slots, and an observation window is fixedly connected to the middle of the sliding door.

[0015] Through the above technical solution: a sliding door is installed between the adjacent door frame and the door groove, which can smoothly slide left and right within the track of the door frame and the door groove, thereby achieving selective isolation and communication between the internal space of the shell and the external environment. An observation window is embedded and fixedly connected in the middle of the sliding door, which can clearly observe the condition inside the shell.

[0016] As a further description of the above technical solution:

[0017] A handle is fixedly connected near the edge of the sliding door, and an exhaust fan is fixedly connected to the top of the outer casing.

A ventilation fan is fixedly installed on the top of the casing. The ventilation fan has efficient ventilation capacity and low noise operation characteristics, which can promptly exhaust the polluted air inside the casing and introduce fresh outside air, creating favorable conditions for the stable operation of the equipment.

[0019] As a further description of the above technical solution:

[0020] A rotating cylinder is rotatably connected to the outer wall of the limiting column, and a limiting block is fixedly connected to the top of the limiting column.

[0021] Through the above technical solution: when the device is running, the rotating drum can rotate flexibly around the outer wall of the limiting column, providing a stable and smooth guarantee for the fixation of the circuit board. Meanwhile, a limiting block is firmly fixed to the top of the limiting column, which effectively prevents the rotating drum from accidentally detaching from the limiting column during rotation, thereby ensuring the integrity and reliability of the entire structure.

[0022] As a further description of the above technical solution:

[0023] The top outer wall of the lead screw is threaded with a fastening nut, and the baffle is conical.

[0024] Through the above technical solution: the top outer wall of the lead screw interacts with the fastening nut in the form of a threaded connection. By rotating the fastening nut, the position of the lead screw in the vertical direction can be precisely adjusted to apply a suitable fastening force. The baffle is conical, which cleverly changes the flow direction of the material and restricts the movement range of the material.

[0025] As a further description of the above technical solution:

[0026] The top surface of the base plate is provided with a sliding groove, and the inner wall of the sliding groove is slidably connected to the outer wall of the sliding rod.

[0029] 1. In this utility model, the circuit board is placed in the middle of the base plate, the motor is started, the motor drives the turntable to rotate, the turntable drives one end of the connecting rod to rotate, so that the connecting rod pulls the sliding rod to slide on the inner wall of the slide groove. When the two rotating cylinders contact the edge corner of the circuit board, the right-angle block rotates, so that the right angle of the right-angle block locks the right angle of the circuit board, thereby fixing the circuit board in position. This can improve the accuracy of spraying and ensure the uniformity of the coating.

In this utility model, the telescopic rod can precisely control the distance between the nozzle and the circuit board, and the baffle can effectively block paint splashing without affecting the spraying operation of the nozzle.
