Description

Technical Field

[0001] The utility model relates to the technical field of circuit board processing, in particular to a circuit board blind groove processing device. Background Art

[0002] Circuit board, also known as PCB board, is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components in electronic machinery. In order to meet the installation of components such as circuit boards, the circuit board needs to be processed by a slotting machine in the prior art to open a blind slot on the circuit board.

[0003] But it still has the following disadvantages in actual use:

[0004] When using a laser hole opener to open blind grooves on existing circuit boards, manual positioning of the circuit board is required each time to ensure that the position of the blind groove opened by the laser hole opener is the same. A positioning plate is usually used for positioning, which is cumbersome to operate and there is still a certain error in positioning, making the efficiency of opening the blind groove of the circuit board relatively slow and inconvenient to use. Utility Model Content

[0005] The purpose of the utility model is to provide a circuit board blind groove processing device to solve the problem raised in the above background technology that when a laser hole opener is used to open a blind groove on the existing circuit board, the circuit board needs to be manually positioned each time to ensure that the position of the blind groove opened by the laser hole opener is the same. A positioning plate is usually used for positioning, which is cumbersome to operate and there is still a certain error in positioning, which makes the efficiency of opening the blind groove of the circuit board relatively slow and inconvenient to use.

[0006] In order to solve the above technical problems, the utility model provides a circuit board blind groove processing device, comprising:

[0007] a processing assembly, the processing assembly comprising a base plate;

[0008] A positioning assembly, the positioning assembly includes fixed blocks connected to the four corners of the upper end of the base plate, an electric telescopic rod penetrating the internal position of the fixed block, a movable block connected to the inner side of the electric telescopic rod, a clamping block connected to the bottom end of the movable block, a telescopic spring connected to the inner side of the fixed block, a clamping plate connected to the outer end of the telescopic spring, and a clamping slot opened at the upper end of the clamping plate.

[0009] Furthermore, the processing assembly also includes a support frame connected to the upper end of the base plate and a laser hole opener connected to the inner side of the upper end of the support frame.

[0010] Furthermore, the fixing block and the clamping plate are L-shaped structures, and the clamping plate is located inside the fixing block.

[0011] Furthermore, the card slot is opened relative to the card block, and the outer end of the card block exceeds the outer side position of the lower end of the movable block.

[0012] Furthermore, it also includes a fixing component, which includes a hollow groove opened at an inner position of the bottom plate, a hollow circular groove opened at an upper position of the bottom plate, through holes opened at both sides of the bottom plate, an air intake pipe connected to one side of the bottom plate, and an air inlet pipe connected to the other side of the bottom plate.

[0013] Furthermore, the through hole is connected to the hollow groove and the hollow circular groove, the outer end of the suction pipe is connected to an suction pump, and the outer end of the air inlet pipe is connected to an air blowing pump.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows: by setting a positioning component, when it is necessary to position the circuit board, the electric telescopic rod is shortened outwardly, so that the electric telescopic rod drives the movable block and the card block to move inwardly. When the card block enters the inside of the card slot, the movable block drives the clamping plate to move outwardly through the card block, so that the telescopic spring is compressed and the circuit board is placed on the inner side of the clamping plate. At this time, the electric telescopic rod is controlled to extend inwardly. When the movable block and the clamping plate are separated, the circuit board is clamped under the elastic force of the telescopic spring. Since the telescopic spring will maintain equal elastic force without being affected by external force, the circuit board can be located in the central position of the upper end of the bottom plate, the operation is simple and the positioning is accurate. At the same time, by setting a fixing component, when the circuit board is positioned, the air inside the hollow groove is sucked outwardly by the suction pump, so that the inside of the hollow groove is maintained in a negative pressure state, so that the circuit board is adsorbed at the upper end position of the bottom plate, so that the circuit board cannot move when the blind groove is opened, thereby increasing the accuracy of opening the blind groove.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 As shown, this embodiment is a circuit board blind groove processing device, comprising:

[0023] A processing assembly 1, the processing assembly 1 comprises a base plate 11;

[0024] The positioning assembly 2 includes a fixed block 21 connected to the four corners of the upper end of the bottom plate 11, an electric telescopic rod 22 penetrating the inner position of the fixed block 21, a movable block 23 connected to the inner side of the electric telescopic rod 22, a clamping block 24 connected to the bottom end of the movable block 23, a telescopic spring 25 connected to the inner side of the fixed block 21, a clamping plate 26 connected to the outer end of the telescopic spring 25, and a clamping slot 27 provided at the upper end of the clamping plate 26;

[0025] The fixed block 21 is used to support the electric telescopic rod 22, the electric telescopic rod 22 is used to drive the movable block 23 to move, the movable block 23 is used to support the clamping block 24, the clamping block 24 is used to engage with the clamping slot 27, the telescopic spring 25 is used to reset the clamping plate 26, and the clamping plate 26 is used to clamp the outer side of the circuit board;

[0026] The processing assembly 1 further includes a support frame 12 connected to the upper end of the base plate 11 and a laser hole opener 13 connected to the inner side of the upper end of the support frame 12;

[0027] The support frame 12 is used to support the laser hole opener 13, and the laser hole opener 13 is used to open blind grooves on the circuit board;

[0028] The fixing block 21 and the clamping plate 26 are L-shaped structures, and the clamping plate 26 is located inside the fixing block 21;

[0029] The clamping plate 26 can move inside the movable block 23 and drive the telescopic spring 25 to be compressed;

[0030] The card slot 27 is opened relative to the card block 24, and the outer end of the card block 24 exceeds the outer side of the lower end of the movable block 23;

[0031] When the clamping block 24 is located inside the clamping slot 27, the movement of the clamping block 24 will drive the movement of the clamping plate 26;

[0032] Working principle: When it is necessary to position the circuit board on the upper end of the bottom plate 11, the electric telescopic rod 22 is controlled to shorten outward, and the shortening of the electric telescopic rod 22 drives the movable block 23 to move outward, and the movable block 23 moves outward to drive the clamping block 24 to move outward and enter the inside of the clamping slot 27. When the clamping block 24 is engaged in the inside of the clamping slot 27, the movable block 23 can drive the clamping plate 26 to move outward, and the clamping plate 26 moves outward to drive the telescopic spring 25 to be compressed. At this time, the circuit board is placed at the upper end of the bottom plate 11. The electric telescopic rod 22 is arranged inwardly and controls the electric telescopic rod 22 to extend inwardly. The inward extension of the electric telescopic rod 22 drives the movable block 23 and the clamping block 24 to move inwardly. The clamping plate 26 moves inwardly under the elastic force of the telescopic spring 25. When the movable block 23 and the clamping block 24 move to be separated from the clamping plate 26, the clamping plate 26 and the telescopic spring 25 are not affected by external force. Since the two sets of telescopic springs 25 will maintain equal elastic force when not subject to external force, the circuit board is located at the central position of the upper end of the bottom plate 11, thereby realizing the positioning of the circuit board.

[0033] See also Figure 4 As shown, this embodiment is based on the above embodiment and also includes:

[0034] The fixing assembly 3 includes a hollow groove 31 opened at an inner position of the bottom plate 11, a hollow circular groove 32 opened at an upper end position of the bottom plate 11, through holes 33 opened at both sides of the bottom plate 11, an air intake pipe 34 connected to one side of the bottom plate 11, and an air inlet pipe 35 connected to the other side of the bottom plate 11;

[0036] The through hole 33 is connected to the hollow groove 31 and the hollow circular groove 32, the outer end of the suction pipe 34 is connected to the suction pump, and the outer end of the air inlet pipe 35 is connected to the blowing pump;

[0037] The suction pump can discharge the air inside the hollow groove 31 to the outside through the suction pipe 34 to form a negative pressure, and the intake pump can blow air into the hollow groove 31 through the intake pipe 35 to form a positive pressure;

[0038] Working principle: When the circuit board needs to be fixed after being positioned, the suction pump is started, and the suction pump discharges the air inside the hollow groove 31 to the outside through the suction pipe 34. At this time, negative pressure is formed inside the hollow groove 31 to adsorb the bottom of the circuit board through the hollow circular groove 32, thereby completing the fixation of the circuit board;

[0039] When the circuit board needs to be removed, the suction pump is stopped and the blowing pump is started. The blowing pump blows outside air into the hollow groove 31 through the air inlet pipe 35, forming a positive pressure inside the hollow groove 31, and the air passes through the hollow circular groove 32 to apply an upward force to the circuit board, so that the circuit board and the base plate 11 are separated, thereby making it easy to remove the circuit board.
