Description

Technical Field

[0001] This utility model relates to the field of flexible circuit board processing technology, specifically to a feeding device for flexible circuit board processing. Background Technology

[0002] Flexible printed circuit boards (FPCs) are printed circuit boards made of flexible insulating substrates. They have many advantages that rigid printed circuit boards do not have. They can be bent, rolled and folded freely. FPCs are widely used in aerospace, military, mobile communications, laptops, computer peripherals, PDAs and digital cameras.

[0003] The processing of flexible circuit boards involves multiple steps. When switching between steps, the flexible circuit board needs to be transferred from one processing table to another. The traditional feeding method is to manually pick up the flexible circuit board. This method is not only time-consuming and labor-intensive, but also easily contaminates the flexible circuit board. Although some automatic feeding devices can automatically grab the flexible circuit board, the clamping force is not easy to control, which can easily damage the flexible circuit board. Utility Model Content

[0004] The purpose of this invention is to provide a feeding device for processing flexible circuit boards, so as to solve the problems mentioned in the background art.

[0006] A gripping mechanism is provided at the bottom of the second drive block, and a cylinder is provided inside the gripping mechanism. A telescopic rod is provided at the output end of the cylinder, and the cylinder 14 is used to drive the telescopic rod 16 to extend and retract.

[0007] An air chamber is located at the bottom of the gripping mechanism. The bottom of the telescopic rod extends into the air chamber, and a rubber block is provided at the bottom end of the telescopic rod. The cylinder 14 drives the rubber block 15 to move up and down through the telescopic rod 16, thereby adjusting the air pressure in the air chamber 11.

[0008] A disc, which is hollow, has its top connected to an air chamber and negative pressure suction nozzles evenly distributed at its bottom, with the tops of the nozzles all connected to the disc, for adsorbing flexible circuit boards.

[0009] Preferably, a guide rod is fixed at the top of the main body of the feeding device, and the top of the second driving block is slidably sleeved with the guide rod through a guide sleeve.

[0010] Preferably, a lifting mechanism is provided on one side of the main body of the feeding device, and a first lead screw is provided on one side inside the lifting mechanism. A first driving block is sleeved on the first lead screw, and one end of the first driving block is connected to the main body of the feeding device.

[0011] Preferably, a first rotary drive mechanism is fixed to the top of the lifting mechanism, and the output end of the first rotary drive mechanism is connected to a first lead screw.

[0012] Preferably, the bottom of the lifting mechanism is fixed with an installation component, and the installation component is evenly provided with fixing bolts.

[0013] Preferably, the bottom ends of the fixing bolts are all locked with nuts, and the end of the nut near the mounting part is provided with a bulge, and an elastic element is provided between the bulge and the nut.

[0014] Preferably, the elastic elements are all made of rubber strips with an arched structure, and both ends of the elastic elements abut against the bulge.

The second rotary drive mechanism drives the second lead screw to rotate, causing the second drive block and the gripping mechanism to move above the flexible circuit board. Then, the cylinder drives the rubber block to move upward through the telescopic rod, which reduces the air pressure in the air chamber. The disc has a hollow structure and is connected to the air chamber and the negative pressure suction nozzle, allowing the negative pressure suction nozzle to adsorb and grip the flexible circuit board, and then transfer it to the subsequent processing platform. This facilitates the feeding of the flexible circuit board, is less likely to cause contamination to the flexible circuit board, and is less likely to damage the flexible circuit board compared with the gripping method of a clamping robotic arm.

[0023] A second rotary drive mechanism 6 is fixed at one end of the top of the main body 9 of the feeding device, and the output end of the second rotary drive mechanism 6 is connected to the second lead screw 7 through a pulley mechanism to drive the second lead screw 7 to rotate, so that the second drive block 8 moves along the second lead screw 7.

[0024] The gripping mechanism 10 is located at the bottom of the second drive block 8. The second rotary drive mechanism 6 drives the second lead screw 7 to rotate, so that the second drive block 8 and the gripping mechanism 10 move above the flexible circuit board.

[0025] A guide rod is fixed at the top of the main body 9 of the feeding device. The top of the second driving block 8 is slidably connected to the guide rod through a guide sleeve to guide and limit the second driving block 8.

[0026] The gripping mechanism 10 is equipped with a cylinder 14 inside, and a telescopic rod 16 is provided at the output end of the cylinder 14. The air chamber 11 is located at the bottom of the gripping mechanism 10, and the bottom of the telescopic rod 16 extends into the air chamber 11. A rubber block 15 is provided at the bottom end of the telescopic rod 16.

[0027] The cylinder 14 drives the rubber block 15 to move upward through the telescopic rod 16, which reduces the air pressure in the air chamber 11. The disc 13 is a hollow structure, and the top of the disc 13 is connected to the air chamber 11. The bottom of the disc 13 is evenly distributed with negative pressure suction nozzles 12, and the top of each negative pressure suction nozzle 12 is connected to the disc 13.

[0028] The disc 13 has a hollow structure and is connected to the air chamber 11 and the negative pressure suction nozzle 12, so that the negative pressure suction nozzle 12 can adsorb and grab the flexible circuit board and then transfer it to the subsequent processing platform. The cylinder 14 drives the rubber block 15 to move down, so that the negative pressure suction nozzle 12 releases the flexible circuit board for feeding, which is less likely to cause contamination and damage to the flexible circuit board.

[0029] A lifting mechanism 2 is provided on one side of the main body 9 of the feeding device, and a first lead screw 3 is provided on one side inside the lifting mechanism 2. A first driving block 4 is sleeved on the first lead screw 3, and one end of the first driving block 4 is connected to the main body 9 of the feeding device.

[0030] The top of the lifting mechanism 2 is fixed with a first rotary drive mechanism 5, and the output end of the first rotary drive mechanism 5 is connected to the first lead screw 3;

[0031] The first rotary drive mechanism 5 on the lifting mechanism 2 can drive the first lead screw 3 to rotate, so that the first drive block 4 drives the feeding device body 9 to move along the first lead screw 3, thereby adjusting the height position of the feeding device body 9 and the gripping mechanism 10, making it suitable for different flexible circuit board processing tables.

[0032] The bottom of the lifting mechanism 2 is fixed with a mounting part 1, and the mounting part 1 is evenly provided with fixing bolts 17. The device is fixedly installed above the two processing tables of the flexible circuit board by the mounting part 1 and the fixing bolts 17.

[0034] All elastic elements 20 are made of arched rubber strips, and both ends of the elastic elements 20 abut against the bulge 18;

[0035] When subjected to external force, the elasticity of the elastic element 20 can disperse and buffer the external force, making the nut 19 less likely to loosen, and thus making the device more stable after it is fixed.

[0036] The specific models and specifications of the first rotary drive mechanism 5, the second rotary drive mechanism 6, and the cylinder 14 need to be determined by selection calculation based on the specifications and parameters of the device. The selection calculation method is existing technology, so it will not be described in detail here.

[0037] Working principle: In this embodiment, the device is fixedly installed above the two processing tables of the flexible circuit board using the mounting part 1 and fixing bolt 17. The second rotary drive mechanism 6 drives the second lead screw 7 to rotate, causing the second drive block 8 and the gripping mechanism 10 to move above the flexible circuit board. Then, the cylinder 14 drives the rubber block 15 to move upward through the telescopic rod 16, which reduces the air pressure in the air chamber 11. The disc 13 has a hollow structure and is connected to the air chamber 11 and the negative pressure suction nozzle 12, so that the negative pressure suction nozzle 12 can adsorb and grip the flexible circuit board and then transfer it to the subsequent processing platform. The cylinder 14 drives the rubber block 15 to move downward, so that the negative pressure suction nozzle 12 releases the flexible circuit board for feeding, which is less likely to cause contamination and damage to the flexible circuit board. In addition, the first rotary drive mechanism 5 on the lifting mechanism 2 can drive the first lead screw 3 to rotate, causing the first drive block 4 to drive the feeding device body 9 to move along the first lead screw 3, thereby adjusting the height position of the feeding device body 9 and the gripping mechanism 10 to make it suitable for different flexible circuit board processing tables.
