Description

Technical Field

[0002] The circuit board is a type of carrier that connects electronic components. It can achieve electrical connection with the electronic components carried inside through internal conductive layers and insulating layers. The circuit board can provide stable support for electronic components and ensure the stability of electronic components when working. The circuit board is one of the important components in various electronic devices. It can receive and send data signals in electronic devices and is widely used in electronic devices such as calculators and mobile phones.

[0003] The circuit board needs to go through multiple stages during the production process, such as the circuit board stripping and etching process. Through this process, the dry film or wet film on the outside of the circuit board can be removed. The circuit board after stripping can reveal the etched circuit, which can facilitate subsequent processing and other operations. When stripping the film, the staff needs to place the circuit board into the interior of the processing equipment. Multiple sets of driving wheels are installed inside the processing equipment to drive the circuit board to move inside the device. The staff needs to avoid stacking and overlapping of the circuit boards when placing them. When the circuit boards overlap, it will affect the normal stripping process of the circuit boards. Therefore, the staff needs to place the two groups of circuit boards in a reasonable order based on experience. The staff needs to stare at the feeding port of the equipment for a long time, which is prone to placement errors after a long time. The circuit board cannot be automatically placed from the feeding port. In order to solve this technical problem, the utility model proposes a device that is convenient for stripping and etching of circuit boards. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

The adjusting component includes components such as threaded rods, and the spacing between the upper and lower driving wheels 18 can be adjusted through the adjusting component, so that circuit boards of different thicknesses can be transported, and the applicability is wider.

[0023] A fixing frame 2 is installed on the outside of the control box 1, and multiple groups of fixed shafts 3 are rotatably connected inside the fixing frame 2. The multiple groups of fixed shafts 3 are symmetrically arranged up and down. A control motor is installed on the outside of the fixing frame 2, and the multiple groups of fixed shafts 3 can be controlled to rotate by the control motor. Fixed wheels 4 are fixedly installed on the outer surfaces of the multiple groups of fixed shafts 3. The outside of the fixed wheels 4 is covered with connecting belts 5. Two groups of connecting belts 5 are provided and are symmetrically arranged. When the fixed shafts 3 rotate, the connecting belts 5 can be driven to rotate.

[0024] A fixing rod 6 is fixedly installed inside the connecting belt 5, and a support plate 7 is detachably connected to the inside of the fixing rod 6. The support plate 7 and the fixing rod 6 are connected by fixing bolts, which facilitates the disassembly of the support plate 7 and maintenance. A clamping plate 8 is slidably connected to the outer surface of the support plate 7, and circuit boards can be placed outside the two groups of clamping plates 8. The clamping plate 8 is an L-shaped structure and multiple groups are provided. The L-shaped structure of the clamping plate 8 can limit the two sides of the circuit board to ensure the stability of the circuit board when it moves.

[0025] A connecting plate 12 is fixedly installed inside the support plate 7, and a fixing groove 13 is opened inside the connecting plate 12. A fixing block 14 is slidably connected inside the fixing groove 13. A baffle is installed inside the connecting plate 12, and the upper part of the fixing block 14 can be limited by the baffle. The fixing block 14 can only move to the left and right sides under the limitation of the connecting plate 12 and the fixing groove 13. The upper surface of the fixing block 14 is connected to the lower surface of the clamping plate 8. The position of the clamping plate 8 can be adjusted by adjusting the position of the fixing block 14. The position of the fixing block 14 can be adjusted according to the size of different circuit boards, and can adapt to circuit boards of more sizes.

[0026] A plurality of fixing holes 15 are provided inside the connecting plate 12, and a screw 16 is connected to the internal thread of the fixing hole 15.

After the push plate 11 performs one action, the connecting belt 5 continues to rotate, and can repeatedly push the circuit board on the clamp 8 into the interior of the processing box 17. The intermittent transportation of the circuit board by the connecting belt 5 can prevent the circuit boards from overlapping when they are placed.

At this time, put the circuit board into the left clamping plate 8, and the connecting belt 5 can be rotated to move the circuit board to the center position of the processing box 17. At this time, the connecting belt 5 stops rotating, and the cylinder 10 drives the push plate 11 to move. The push plate 11 can push the circuit board into the interior of the processing box 17. After the push plate 11 moves once, the connecting belt 5 continues to rotate, and can intermittently and repeatedly push the circuit board into the interior of the processing box 17 to prevent the circuit boards from stacking.
