Description

Technical Field

[0001] The invention belongs to the field of circuit board production, and in particular relates to a circuit board production clamping device. Background Art

[0002] Circuit boards can be divided into ceramic circuit boards, alumina ceramic circuit boards and aluminum nitride ceramic circuit boards according to their manufacturing materials. During the production and processing of circuit boards, when electrical components need to be welded to the circuit boards, in order to ensure welding accuracy and improve the production and processing efficiency of circuit boards, it is often necessary to use circuit board clamping devices used in circuit board production to assist in fixing them.

[0003] During the processing and production of existing circuit boards, it is usually necessary to continuously weld electronic components or punch holes on both sides of the board, resulting in the need to continuously flip the circuit boards during processing. When operating on both sides of the circuit board, the existing circuit board clamping device needs to remove the circuit board, turn the circuit board over and reinstall it, affecting the production efficiency of the circuit board. When welding electronic components or punching holes in the circuit board, waste chips will be generated, and the waste chips remaining on the circuit board usually need to be cleaned up separately. Moreover, during welding and punching, the welding head and drill bit are likely to exert pressure on the surface of the circuit board. Thinner circuit boards may be bent or even broken due to excessive force, thereby causing damage to the circuit board.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0031] Among them, a rubber pad 14 is provided on one side of the two limit grooves, which is used to protect the two sides of the circuit board when the two clamping plates 5 clamp the two sides of the circuit board, thereby reducing the situation where the circuit board is squeezed and damaged by the clamping plates 5;

[0032] A collecting box 4 is provided on the concave base 1 for collecting waste chips dropped from the circuit board when the movable frame 3 drives the circuit board to flip.

[0033] One aspect of the application of this embodiment is: when the circuit board needs to be clamped and processed, the circuit board to be processed is first placed inside the movable frame 3, and the relative moving component 8 is started. The relative moving component 8 is started to drive the two clamping plates 5 to move relative to each other. When the side of the circuit board enters the two limit grooves, the extrusion block 12 clamps the upper and lower sides of the circuit board through elastic force, and the circuit board is processed using welding equipment or punching equipment;

[0034] When the other side of the circuit board needs to be processed, the first motor 6 is started, and the first motor 6 drives the movable frame 3 to flip between the two side panels 2 through the output end. The flipping of the movable frame 3 drives the circuit board to flip, and the other side of the circuit board can be processed. In the process of the first motor 6 driving the movable frame 3 to flip, the continuous impact component 19 is driven to continuously impact the side of the movable frame 3, so that the vibration generated by the impact can be transmitted to the circuit board through the movable frame 3. During the flipping process, the circuit board vibrates and shakes the remaining waste into the collection box 4 for collection. It should be noted that all electrical equipment involved in this application can be powered by batteries or external power supplies.

[0035] By means of the movable frame 3 provided between the two side panels 2, the relatively movable component 8 can drive the two clamping plates 5 to clamp the circuit board in the movable frame 3, and the first motor 6 can drive the circuit board in the movable frame 3 to flip over, so as to facilitate the processing of both sides of the circuit board, reduce the steps of re-disassembling and re-turning the circuit board, and thus improve the efficiency of processing both sides of the circuit board; by means of the continuous impact component 19 provided on one of the side panels 2, in the process of the first motor 6 driving the movable frame 3 to flip over, the continuous impact component 19 is driven to continuously impact the side of the movable frame 3, so that the vibration generated by the impact can be transmitted to the circuit board through the movable frame 3, and the residual waste chips of the circuit board are shaken off by the vibration during the flipping process, thereby reducing the need for additional cleaning of the residual waste chips on the circuit board; by means of the supporting wooden board 9 provided in the movable frame 3, the supporting wooden board 9 can be driven by the adjusting component 10 to move up and down to support the area of ​​the thinner circuit board that needs to be processed, thereby reducing the situation in which the circuit board is damaged due to excessive surface force on the circuit board during processing, such as bending or breaking.

[0036] like Figure 2 As shown, a groove 7 is provided on one side of the inner wall of the movable frame 3 of this embodiment, and a relatively movable assembly 8 is located in the groove 7;

[0037] like Figure 2-3As shown, specifically, the specific structure of the relative moving component 8 includes: a bidirectional threaded rod 801 that is rotatably fitted in the groove 7, two first threaded blocks 802 that are slidably fitted in the groove 7 and threadedly fitted in two thread directions of the bidirectional threaded rod 801, and a second motor 803 is arranged on one side of the movable frame 3, the end of the bidirectional threaded rod 801 passes through the movable frame 3 and is fixedly connected to the output end of the second motor 803, and the two first threaded blocks 802 are respectively fixedly connected to one side of the two clamping plates 5; a plurality of springs 13 are fixedly connected between the limit groove and the extrusion block 12, and a rounded corner is arranged on the side of the extrusion block 12 that contacts the circuit board.

[0038] When the second motor 803 is started, the output end of the second motor 803 drives the bidirectional threaded rod 801 to rotate, and the rotation of the bidirectional threaded rod 801 drives the two first threaded blocks 802 to move relative to each other in the groove 7. The relative movement of the two first threaded blocks 802 drives the two clamping plates 5 to move relative to each other. The two clamping plates 5 move relative to each other to clamp the two side edges of the circuit board. When the two side edges of the circuit board enter the limiting groove, the side edges of the circuit board are squeezed with rounded corners to move the squeezing block 12 upward. When the side edges of the circuit board completely enter the limiting groove, the squeezing block 12 clamps and fixes the upper and lower sides of the circuit board through the elastic force of multiple springs 13. The two clamping plates 5 clamp and fix the two side edges of the circuit board, thereby facilitating the clamping and fixing of the circuit board in the movable frame 3.

[0041] When it is necessary to process the surface of a thinner circuit board, the knob 1003 is turned. The rotation of the knob 1003 drives the threaded rod 1002 to rotate. The rotation of the threaded rod 1002 drives the second threaded block 1004 to move in the fixed groove 1001. The movement of the second threaded block 1004 drives the supporting wooden board 9 to move up and down, so that the supporting wooden board 9 can move up and down to support the area of ​​the thinner circuit board that needs to be processed, thereby reducing the situation where the circuit board is damaged due to excessive force on the surface during processing, causing bending or breaking.

[0045] When the other side of the circuit board needs to be processed, the first motor 6 is started. The first motor 6 drives the movable frame 3 to flip between the two side plates 2 through the output end. The flipping of the movable frame 3 drives the circuit board to flip, so that the other side of the circuit board can be processed. In the process of the first motor 6 driving the movable frame 3 to flip, the movable frame 3 drives the connecting rod 20 to rotate, the rotation of the connecting rod 20 drives the worm 16 to rotate, the rotation of the worm 16 drives the worm gear 18 to rotate, the rotation of the worm gear 18 drives the disc to rotate through the rotating rod 17, the rotation of the disc engages with the multiple racks 1903 on both sides of the movable frame 1902 through multiple teeth, respectively, drives the movable frame 1902 to reciprocate in the inner cavity 15, the reciprocating movement of the movable frame 1902 in the inner cavity 15 drives the impact block 1904 to reciprocate, the reciprocating movement of the impact block 1904 continuously impacts the side of the movable frame 3, the vibration generated by the impact can be transmitted to the circuit board through the movable frame 3, and the residual waste chips are shaken into the collection box 4 by vibration during the flipping process of the circuit board, thereby reducing the need for additional cleaning of residual waste chips on the circuit board.
