[0001] The utility model relates to the technical field of electronic component processing, in particular to a clamping device. Background Art

[0002] The clamping device for electronic component production is a device or tool used to fix, clamp or position components during the manufacturing process of electronic components. These clamping devices can be used in various production links, including assembly, welding, testing, etc. Among electronic components, circuit boards are widely used. When processing circuit boards, horizontal clamping devices are usually used for processing. Existing clamping devices usually use multiple clamps to fix the circuit board on the surface of the operating table, and then the staff processes the circuit board on the operating table. However, when the circuit board needs to be clamped and processed vertically, the circuit board is processed. In the process of taking the processed circuit board inside the device, the clamp on the outside of the circuit board plays a certain role in limiting and shielding the circuit board, which makes it inconvenient to take out the circuit board.

[0003] The implementation of the utility model aims to provide a clamping device to solve the problems raised in the above background technology. Utility Model Content

[0025] Example

[0026] Reference Figure 1-4A clamping device comprises a device body 1, a vacuum suction cup 5 and an equipment box 7. The bottom of the device body 1 is a bottom base, and an operation panel is provided at the upper end of the bottom base. A vacuum suction cup 5 is provided on the inner side of the device body 1, and an equipment box 7 is provided on the outer side of the device body 1. A suction cup air pipe 11 is provided on the other side of the vacuum suction cup 5, and an air guide pipe 12 is connected through the other end of the suction cup air pipe 11, and a negative pressure air pump 10 is provided through the other end of the air guide pipe 12. A placement groove 4 is provided on the upper end of the device body 1, and the placement groove 4 runs through the upper half of the device body 1. A pick-up groove 3 is penetrated on the side of the device body 1. A sponge pad 6 is fixedly connected to the inner surface of the device body 1. Two air guide pipes 12 are provided, and one air guide pipe 12 connects the suction cup air pipe 11 and the negative pressure air pump 10, and one end of the other air guide pipe 12 is connected to the negative pressure air pump 10, and the other end of the air guide pipe 12 is connected through the air outlet 13. There are four vacuum suction pipes 12 on the inner side of the device body 1 Plate 5, four vacuum suction cups 5 are equidistantly arranged at the four corners of the inner side of the device body 1, so that the four vacuum suction cups 5 can provide uniform adsorption force to avoid the circuit board from being unevenly stressed and shaking. When processing the circuit board, the staff can insert the circuit board from the placement slot 4 at the upper end of the device body 1 into the inner side of the device body 1. This process can be manually inserted or automatically input through an external conveying mechanism. When the circuit board slides from the inner side of the placement slot 4 to the inner side of the device body 1, the sponge pad 6 at the bottom of the device body 1 can play a buffering role to avoid the circuit board from being damaged during the falling process. After the circuit board slides into the inner side of the device body 1, the staff can start the negative pressure air pump 10 through the external controller, so that the negative pressure air pump 10 draws the inner side of the vacuum suction cup 5 into a negative pressure state through the air guide tube 12. Through this operation, the circuit board is adsorbed on its surface by the vacuum suction cup 5. After the circuit board is adsorbed, the staff can perform processing operations on the surface of the circuit board.

[0027] A push plate 16 is provided at the inner center of the device body 1, and a hydraulic rod 15 is fixedly connected to the bottom of the push plate 16, and a hydraulic pump 14 is provided at the other end of the hydraulic rod 15. The vacuum suction cup 5 is divided into two parts, and a silicone sealing ring 8 is fixedly connected between the two parts. A spring 17 is provided on the inner side of the silicone sealing ring 8. The push plate 16 is composed of a support plate and a rubber pad as a whole, and the rubber pad is fixedly connected to the surface of the support plate. The right side of the placement groove 4 runs through the device body 1 as a whole, and the pick-up groove 3 is located on the right side of the placement groove 4. The pick-up groove 3 runs through the device body 1 and the placement groove 4 as a whole. When the circuit board processing is completed, the staff can turn off 10, and then the staff can start the hydraulic pump 14 through the external controller, so that the hydraulic pump 14 controls the extension and retraction of the push plate 16 through the hydraulic rod 15, and the push plate 16 moves outward to assist the circuit board to separate from the vacuum suction cup 5, and at the same time, the push plate 16 The rubber pad on the surface can play a buffering role when it contacts the circuit board, preventing the circuit board from being damaged during the push of the push plate 16. During this process, the spring 17 on the inside of the vacuum suction cup 5 can play a buffering role. Through the expansion and contraction of the spring 17, the vacuum suction cup 5 can move outward with the circuit board, so that the circuit board slowly separates from the vacuum suction cup 5, avoiding the circuit board suddenly separating from the vacuum suction cup 5 and causing damage to the contact point between the circuit board and the vacuum suction cup 5. At the same time, during the process of the circuit board being adsorbed and fixed on the surface of the vacuum suction cup 5, the spring 17 can shrink under the suction force generated by the vacuum suction cup 5, so that the two parts of the vacuum suction cup 5 are fitted together, avoiding the circuit board from moving inward during the processing of the circuit board. After the circuit board separates from the vacuum suction cup 5, the staff can reach their hand into the removal slot 3, contact the circuit board through the removal slot 3, and pull the circuit board out from one side of the removal slot 3.

[0028] The protective plate 2 as a whole is a hollow rectangular frame, and a fill light 9 is provided on one side of the protective plate 2 close to the vacuum suction cup 5, so that when the staff is processing the circuit board, the fill light 9 inside the protective plate 2 can play a role of auxiliary lighting.

[0029] Working principle: When processing circuit boards, the staff can insert the circuit boards from the placement slot 4 at the upper end of the device body 1 into the inner side of the device body 1. This process can be done manually or automatically through an external conveying mechanism. When the circuit board slides from the inner side of the placement slot 4 into the inner side of the device body 1, the sponge pad 6 at the bottom of the device body 1 can play a buffering role to prevent the circuit board from being damaged during the falling process. After the circuit board slides into the inner side of the device body 1, the staff can start the negative pressure air pump 10 through the external controller, so that the negative pressure air pump 10 draws the inner side of the vacuum suction cup 5 into a negative pressure state through the air duct 12. Through this operation, the circuit board is adsorbed on its surface by the vacuum suction cup 5. After the circuit board is adsorbed, the staff can perform processing operations on the surface of the circuit board.

[0030] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.

[0031] In the description of the present invention, it is necessary to understand that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
