Description

Technical Field

[0001] The utility model relates to the technical field of circuit board detection, in particular to an FPC circuit board adsorption device. Background Art

[0002] Flexible printed circuits (FPCs) are highly reliable and flexible printed circuit boards made from polyimide or polyester film. They feature high wiring density, light weight, thinness, and excellent bendability. During the FPC production process, a suction device is often used to secure the board for easy inspection.

[0003] The existing FPC circuit board adsorption device has a fixed adsorption area. Although some FPC circuit board adsorption devices have the function of adjusting the adsorption area, the adjustment method is mostly to use a sealing plate to move to block the adsorption holes, thereby adjusting the adsorption area. When faced with a circuit board whose length and width are both smaller than the adsorption area of the FPC circuit board adsorption device, the sealing plate can only block the adsorption holes according to the length or width of the circuit board. Some adsorption holes will still be unblocked, which will still lead to an excessively large adsorption area, resulting in energy waste and reducing the practicality of the device. Therefore, in order to solve the above problems, an FPC circuit board adsorption device is proposed. Utility Model Content

[0004] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0005] The technical solution adopted by the present invention to solve its technical problems is as follows: an FPC circuit board adsorption device described in the present invention comprises a workbench, an exhaust hopper is fixedly connected to the inner side of the workbench, a fan is connected to the outer side of the exhaust hopper, an adsorption hole is opened on the surface of the workbench, a sealing column is slidably connected to the inner side of the adsorption hole, a fixed rod is slidably connected to the inner side of the sealing column, a support plate is slidably connected to the outer side of the fixed rod, the support plate and the workbench are fixedly connected, a sealing block is fixedly connected to the lower side of the sealing column, the sealing blocks are fitted together, and the sealing block and the exhaust hopper are used in combination. This step enables the device to face circuits of different sizes by arranging the sealing column and the fixed rod. The board can be separated from the sealing column by pulling the fixing rod at the appropriate position, so that the sealing column falls from the adsorption hole at the appropriate position, and then the fan is started to drive the air to be sucked into the inner side of the adsorption hole separated from the sealing column, so that the adsorption range of the device can be accurately adjusted according to the size of the circuit board, reducing resource waste. By setting the sealing block, the volume of the sealing block is the same as the space inside the exhaust hopper. When the sealing column falls, it will drive the sealing block to fall at the same time, so that part of the space inside the exhaust hopper can be used for exhaust of the fan, so that the space inside the exhaust hopper can be adjusted according to the area of the circuit board at the same time, further reducing the energy required for the operation of the fan, and improving the practicality and environmental protection of the device.

[0006] Preferably, a synchronization block is fixedly connected to the outer side of the fixed rod, and a synchronization rod is slidably connected to the inner side of the synchronization block. In this step, by setting the synchronization block and the synchronization rod, when it is necessary to pull multiple fixed rods at the same time, the synchronization rod can be inserted into the inner sides of the multiple synchronization blocks, and then the synchronization rod is pulled. The multiple synchronization blocks are driven to move by the synchronization rod, and the multiple fixed rods are driven to move by the multiple synchronization blocks, so as to drive the multiple fixed rods to separate from the sealing column at the same time, making the adjustment of the device more convenient.

[0007] Preferably, a convex plate is slidably connected to the inner side of the workbench, and a lifting screw is threadedly connected to the inner side of the convex plate. The lifting screw is rotatably connected to the workbench. This step is achieved by setting the convex plate and the lifting screw. When the device is used, the lifting screw can be rotated to drive the convex plate to rise through the lifting screw, and the sealing block can be pushed up through the convex plate, and the sealing column can be pushed up through the sealing block until it is reinserted into the inner side of the adsorption hole, so that the device can be readjusted, thereby improving the convenience of the device.

[0008] Preferably, a flat gear is fixedly connected to the outside of the lifting screw, and a tooth plate is engaged with the side of the flat gears that are close to each other. This step allows the lifting screws on both sides to rotate simultaneously by setting the tooth plate and the flat gear, thereby facilitating the lifting of the convex plate and improving the convenience of using the device.

[0009] Preferably, a limiting rod is fixedly connected to the inner side of the convex plate, and the limiting rod and the sealing block are slidably connected. In this step, a limiting rod is set and inserted into the inner side of the sealing block so that the moving trajectory of the sealing block can be restricted when it slides up and down, so that the sealing block will not be offset due to sliding and cannot be returned to its original position, thereby improving the stability of the device.

[0010] Preferably, a spring rod is fixedly connected to the inner side of the workbench, and a suction cup is fixedly connected to the lower side of the spring rod. In this step, by setting the spring rod and the suction cup, the suction cup is adsorbed and separated from the desktop, so that the workbench is easy to take away and place, thereby facilitating the adjustment of the device according to different working positions, thereby improving the convenience of using the device.

[0011] The utility model is beneficial in that:

[0012] 1. The utility model provides a sealing column and a fixing rod, so that when facing circuit boards of different sizes, the fixing rod can be pulled to separate from the sealing column at an appropriate position, so that the sealing column falls from the adsorption hole at an appropriate position, and then the fan is started to drive air to be sucked into the inner side of the adsorption hole separated from the sealing column, so that the adsorption range of the device can be accurately adjusted according to the size of the circuit board, thereby reducing resource waste. By providing a sealing block, the volume of the sealing block is the same as the space inside the exhaust hopper. When the sealing column falls, it will drive the sealing block to fall at the same time, so that part of the space inside the exhaust hopper can be used for exhaust by the fan, so that the space inside the exhaust hopper can be adjusted according to the area of the circuit board at the same time, further reducing the energy required for the operation of the fan, and improving the practicality and environmental protection of the device.

[0013] 2. The utility model provides synchronization blocks and synchronization rods. When multiple fixed rods need to be pulled at the same time, the synchronization rods can be inserted into the inner sides of the multiple synchronization blocks, and then the synchronization rods can be pulled. The synchronization rods can drive the multiple synchronization blocks to move, and the multiple synchronization blocks can drive the multiple fixed rods to move, so as to drive the multiple fixed rods to separate from the sealing column at the same time, making the adjustment of the device more convenient.

[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Specific examples are given below.

[0023] See also Figure 1-5As shown, an FPC circuit board adsorption device includes a workbench 1, the inside of the workbench 1 is fixedly connected to an exhaust hopper 2, the outside of the exhaust hopper 2 is connected to a fan 3, the surface of the workbench 1 is provided with an adsorption hole 4, the inside of the adsorption hole 4 is slidably connected to a sealing column 5, the inside of the sealing column 5 is slidably connected to a fixing rod 6, the outside of the fixing rod 6 is slidably connected to a support plate 7, the support plate 7 is fixedly connected to the workbench 1, the lower side of the sealing column 5 is fixedly connected to a sealing block 8, the sealing blocks 8 fit each other, and the sealing block 8 and the exhaust hopper 2 are used in conjunction with each other. In this step, by setting the sealing column 5 and the fixing rod 6, the device can be pulled to the appropriate position when facing circuit boards of different sizes. The fixed rod 6 is separated from the sealing column 5, so that the sealing column 5 falls from the adsorption hole 4 at the appropriate position, and then the fan 3 is started to drive the air to be sucked into the inner side of the adsorption hole 4 separated from the sealing column 5, so that the adsorption range of the device can be accurately adjusted according to the size of the circuit board, reducing resource waste. By setting the sealing block 8, the volume of the sealing block 8 is the same as the space inside the exhaust hopper 2. When the sealing column 5 falls, it will drive the sealing block 8 to fall at the same time, so that part of the space inside the exhaust hopper 2 can be used for exhaust by the fan 3, so that the space inside the exhaust hopper 2 can be adjusted according to the area of the circuit board at the same time, further reducing the energy required for the operation of the fan 3, and improving the practicality and environmental protection of the device.

[0024] Further, such as Figure 1 and Figure 3 As shown, the outer side of the fixed rod 6 is fixedly connected to a synchronization block 9, and the inner side of the synchronization block 9 is slidably connected to a synchronization rod 10. In this step, by setting the synchronization block 9 and the synchronization rod 10, when it is necessary to pull multiple fixed rods 6 at the same time, the synchronization rod 10 can be inserted into the inner side of multiple synchronization blocks 9, and then the synchronization rod 10 is pulled. The synchronization rod 10 drives the multiple synchronization blocks 9 to move, and the multiple synchronization blocks 9 drive the multiple fixed rods 6 to move, so as to drive the multiple fixed rods 6 to separate from the sealing column 5 at the same time, making the adjustment of the device more convenient.

[0025] Further, such as Figure 2 and Figure 3 As shown, the workbench 1 is slidably connected to the inner side of the workbench 1, and the inner side of the convex plate 11 is threadedly connected to the lifting screw 12. The lifting screw 12 is rotatably connected to the workbench 1. This step is performed by setting the convex plate 11 and the lifting screw 12. When the device is used up, the lifting screw 12 can be rotated to drive the convex plate 11 to rise, and the sealing block 8 can be pushed up through the convex plate 11. The sealing column 5 is pushed up through the sealing block 8 until it is reinserted into the inner side of the adsorption hole 4, so that the device can be readjusted, thereby improving the convenience of the device.

[0026] Further, such as Figure 1As shown, a flat gear 13 is fixedly connected to the outside of the lifting screw 12, and a tooth plate 14 is engaged with the side of the flat gear 13 that is close to each other. In this step, the tooth plate 14 and the flat gear 13 are set so that the lifting screws 12 on both sides can rotate simultaneously, thereby facilitating the lifting of the convex plate 11 and improving the convenience of using the device.

[0027] Further, such as Figure 2 and Figure 4 As shown, a limiting rod 15 is fixedly connected to the inner side of the convex plate 11, and the limiting rod 15 is slidably connected to the sealing block 8. In this step, the limiting rod 15 is set and inserted into the inner side of the sealing block 8, so that the movement trajectory of the sealing block 8 can be restricted when sliding up and down, so that the sealing block 8 will not be offset due to sliding and cannot be returned to its original position, thereby improving the stability of the device.

[0028] Further, such as Figure 5 As shown, a spring rod 16 is fixedly connected to the inner side of the workbench 1, and a suction cup 17 is fixedly connected to the lower side of the spring rod 16. In this step, by setting the spring rod 16 and the suction cup 17, the suction cup 17 is adsorbed and separated from the desktop, so that the workbench 1 is easy to take away and place, thereby facilitating the adjustment of the device according to different working positions, thereby improving the convenience of using the device.

[0029] Working principle: according to the size of the circuit board, pull the fixing rod 6 at the appropriate position, separate the fixing rod 6 from the sealing column 5 at the appropriate position, so that the sealing column 5 is separated from the adsorption hole 4, and the sealing block 8 is driven downward by the sealing column 5, so that the sealing block 8 falls on the upper side of the convex plate 11, and cooperates with other sealing blocks 8 to form an air circulation space of appropriate volume, then place the circuit board on the upper side of the adsorption hole 4 without the sealing column 5, start the fan 3, and drive the air to be discharged from between the sealing blocks 8 through the fan 3, so that a low-pressure space is formed between the sealing blocks 8, thereby cooperating with the adsorption hole 4 to adsorb and fix the circuit board. The circuit board is then inspected. When the inspection is completed, the fan 3 is turned off, and the circuit board is picked up. The tooth plate 14 is pulled to move through the engagement of the tooth plate 14 and the flat gear 13, so that the flat gear 13 is driven by the tooth plate 14 to rotate, and the flat gear 13 drives the lifting screw 12 to rotate, and the lifting screw 12 drives the convex plate 11 to move, and the sealing block 8 is pushed up through the convex plate 11, and the sealing column 5 is pushed by the sealing block 8 to block the adsorption hole 4 again, and then the fixing rod 6 is moved so that the fixing rod 6 is inserted into the inner side of the sealing column 5 again, and then the convex plate 11 is returned to its position.
