[0018] The present application has the following advantages:

[0019] 1. By using the hole cleaning mechanism, after the hole is opened, the linear guide rail drives the hole cleaning pipe to move along the X and Y axes, so that the hole cleaning pipe moves directly below the newly opened hole, and the second cylinder works to drive the hole cleaning pipe to rise, so that the hole cleaning pipe extends into the newly opened hole.

[0042] It should be noted that the linear slide rail 64 is arranged as an XY-axis linear slide rail.

[0043] The hole cleaning pipe 61 is arranged as a conical pipe, and the hole cleaning pipe 61 can meet the requirements of being inserted into new holes with different diameters by being arranged as a conical pipe.

[0044] By using the hole cleaning mechanism 6, the linear slide rail 64 drives the hole cleaning pipe 61 to move along the X and Y axes after the hole is formed, so that the hole cleaning pipe 61 is moved to the position directly below the new hole, the second cylinder 62 drives the hole cleaning pipe 61 to rise, so that the hole cleaning pipe 61 is inserted into the new hole, in this process, the air extraction mechanism 7 works to generate suction at the strip-shaped hole 63, when the strip-shaped hole 63 moves to the bottom area of the new hole, dust suction treatment can be performed on the bottom of the circuit board, after being inserted into the hole, dust suction treatment can be performed on the hole, and the part of the strip-shaped hole 63 located at the upper part of the new hole can perform surrounding dust suction treatment on the upper part of the new hole, so that dust and slag can be effectively removed.

[0045] For example, the air extraction mechanism 7 comprises a first air extractor 71, as shown in Figure 6 The air inlet end of the first air extractor 71 is provided with a connecting pipe 72, one end of the connecting pipe 72 is provided with a rotary joint, the rotating part of the rotary joint is fixedly connected with the hole cleaning pipe 61, and the rotary joint is fixedly installed on the telescopic end of the second cylinder 62.

[0046] It should be noted that the air outlet end of the first air extractor 71 is communicated with a collection box 73 for collecting slag.

[0047] By working of the first air extractor 71, suction is generated at the strip-shaped hole 63, when the rotary joint is rotated by the motor, the strip-shaped hole 63 can perform dust suction and slag removal operation on the hole wall of the new hole and on the upper part and the bottom of the circuit board, so that the dust generated during the hole forming process can be effectively reduced to adhere to the hole wall, and the processing quality of the subsequent process can be affected.

[0048] For example, the sliding part 10 comprises a guide rail 11 and a sliding block 12, as shown in Figure 2 and Figure 3The guide rail 11 is fixedly installed on the base 1, and the sliding block 12 is fixedly installed at the bottom of the movable plate 4 and is slidingly installed on the guide rail 11.

[0049] Specifically, in order to enable the movable plate 4 to stably move, the sliding block 12 is slidingly matched with the guide rail 11, so that the movable plate 4 can stably move along a straight line when being driven by the transmission belt, and the stable movement of the movable plate 4 is maintained.

[0050] Specifically, in order to enable the movable plate 4 to stably move, the sliding block 12 is slidingly matched with the guide rail 11, so that the movable plate 4 can stably move along a straight line when being driven by the transmission belt, and the stable movement of the movable plate 4 is maintained. Figure 8 The second cylinder 62 is fixedly installed with a motor 13 at the telescopic end, and the motor 13 is in transmission connection with the hole cleaning pipe 61.

[0051] The hole cleaning pipe 61 is in transmission connection with the motor through a gear and a gear ring.

[0052] The gear ring is fixedly sleeved on the hole cleaning pipe 61, the gear is fixedly connected with the output end of the motor 13, and the gear ring 8 is engaged with the gear 9.

[0053] It should be noted that in the embodiment, the motor 13 is a servo motor, and the two strip-shaped holes 63 are symmetrically arranged relative to the center line of the hole cleaning pipe 61. When the motor 13 works, the hole cleaning pipe 61 is driven to rotate, and the rotation angle of the hole cleaning pipe 61 is set to ±180°, so that the dust collection range of the strip-shaped hole 63 can be increased, and the hole wall of the newly opened hole can be comprehensively treated. In other embodiments, the motor 13 can be a servo motor.

[0054] Specifically, the hole cleaning pipe 61 is provided with a material receiving piece 14, referring to Figure 7 and Figure 8 The material receiving piece 14 includes a material receiving groove 141 and a buffer 15, the material receiving groove 141 can be attached to the bottom of the circuit board, the bottom of the material receiving groove 141 is provided with a rotating piece 16 capable of cleaning the hole wall, and the material receiving groove 141 is fixedly connected with the buffer 15.

[0055] It should be noted that the contact part between the material receiving groove 141 and the bottom of the circuit board is provided with a rubber pad, which can make the material receiving groove 141 and the bottom of the circuit board flexibly contact, effectively preventing the material receiving groove 141 from causing wear to the bottom of the circuit board.

[0056] Specifically, the buffer 15 includes a rotating plate 151, referring to Figure 7 and Figure 8The rotating plate 151 is rotatably installed on the hole cleaning pipe 61, the fixed pipe 152 is fixedly installed on the rotating plate 151, the movable rod 153 is slidably installed on the fixed pipe 152, one end of the movable rod 153 is fixedly connected with the spring 154, one end of the spring 154 is fixedly connected with the inner bottom of the fixed pipe 152, and the end, away from the spring 154, of the movable rod 153 is fixedly connected with the material receiving groove 141.

[0057] It should be noted that, in the embodiment, the rotating plate 151 is rotatably installed on the pipe wall of the hole cleaning pipe 61 by a bearing.

[0058] By using the above scheme, when the hole cleaning pipe 61 rises, the material receiving groove 141 first adheres to the bottom of the circuit board, and in the process of the hole cleaning pipe 61 continuously rising and extending into the hole wall, the movable rod 153 presses the spring 154, the spring 154 is compressed under force, so that the material receiving groove 141 adheres to the bottom of the circuit board without causing damage to the circuit board. When the brush head 161 cleans the hole wall, the material receiving groove can collect the falling material residue and suck it away through the strip-shaped hole, which can effectively prevent the material residue from falling. When the motor drives the hole cleaning pipe 61 to rotate, the spring 154 generates a counterforce, so that the material receiving groove 141 tightly adheres to the bottom of the circuit board without rotating, thereby effectively preventing the bottom of the circuit board from being abraded.

[0059] For example, the rotating part 16 includes a brush head 161 and a connecting plate 162, as shown in Figure 7 - Figure 8 The brush head 161 is fixedly installed on the side of the connecting plate 162, the connecting plate 162 is rotatably installed on the bottom of the material receiving groove 141, the side, away from the brush head 161, of the connecting plate 162 is fixedly connected with a flexible pad 163, and the flexible pad 163 can adhere to the hole cleaning pipe 61.

[0060] It should be noted that, in the embodiment, the brush head 161 is provided as a brush, and two brush heads 161 are symmetrically arranged relative to the center line of the hole cleaning pipe 61, and the brush head 161 is arranged to be close to the strip-shaped hole 63.

[0061] The brush head 161 is installed in a detachable manner, and the installation manner includes but is not limited to clamping or magic tape installation.

[0062] The flexible pad 163 is provided as a silica gel pad, and the flexible pad 163 can increase the contact area of the connecting plate 162 and the hole cleaning pipe 61, so that when the hole cleaning pipe 61 rotates, the friction surface is increased, the hole cleaning pipe 61 drives the connecting plate 162 to rotate, so that the brush head 161 cleans the hole wall.

[0063] With the above scheme, when the second cylinder 62 drives the hole cleaning pipe 61 to extend into the newly opened hole, the material receiving groove 141 is attached to the bottom of the circuit board, and the brush head 161 is in contact with the hole wall. After the hole cleaning pipe 61 is attached to the flexible pad 163, the hole cleaning pipe 61 stops rising. When the motor drives the hole cleaning pipe 61 to rotate, the hole cleaning pipe 61 drives the connecting plate 162 to rotate through the flexible pad 163, so that the brush head 161 rotates to clean the hole wall. Combined with the suction force of the strip-shaped hole 63, the hole wall is cleaned by suction and brushing at the same time. This can avoid the problem that single action cannot effectively clean the residual material in the hole, improve the cleaning quality, and effectively avoid the influence of residual material in the hole on the quality of subsequent production processes.

[0064] Specifically, referring to Figure 5 , the movable plate 4 is in the shape of a frame, and the bottom of the movable plate 4 is provided with a material falling groove 17. The base 1 is detachably provided with a collection groove 18, which is located below the material falling groove 17. The collection groove 18 is used to collect the residual material falling from the material falling groove 17.

[0065] It should be noted that the collection groove 18 is located on the moving path of the material falling groove 17.

[0066] With the above scheme, when the circuit board is being opened, the first cylinder 5 drives the movable plate 4 to move, so that the material falling groove 17 is always located below the support plate, and the residual material generated during the opening process can be collected, thereby effectively reducing the residual material falling on the surface of the base 1.

[0067] In this embodiment, the base 1 is provided with a dust collection mechanism, referring to Figure 1 , Figure 5 and Figure 6 , the dust collection mechanism comprises a dust collection nozzle 25, a second air extractor 26 and a cyclone separator 27. The base 1 is provided with a table surface hole 29 which is in communication with the dust collection nozzle 25. The dust collection nozzle 25 is in communication with the air inlet end of the second air extractor 26. The cyclone separator 27 is in communication with the air outlet end of the second air extractor 26. The dust collection nozzle 25 is fixedly installed in the base 1.

[0068] It should be noted that the dust collection nozzle 25 is in the shape of a strip. The dust collection nozzle 25 is provided with a plurality of dust collection nozzles.

[0069] The air outlet end of the cyclone separator 27 is detachably provided with an activated carbon screen 28.

[0070] It should be noted that the dust collection nozzle 25 is provided with not less than two, and the number of the dust collection nozzles 25 is the same as that of the strip-shaped holes 63.

[0071] The activated carbon screen is provided with an outer frame which is installed on the air outlet end of the cyclone separator 27 through threads, so as to facilitate replacement.

[0072] With the above scheme, by using the dust suction mechanism, when the second air extractor 26 is working, the dust suction nozzle 25 can suck the dust generated when the hole is opened into the cyclone separator 27, and when the inside of the cleaning device is cleaned, the dust on the base 1 can be cleaned into the table hole 29, and then the second air extractor 26 can suck the dust into the cyclone separator 27 for collection, and the exhaust air can pass through the activated carbon net 28 for further filtration, reducing dust exhaust and purifying exhaust air, which can protect the working environment and workers, and facilitate workers to use when cleaning the device.

[0073] The above embodiment has the following effects:

[0074] By using the hole cleaning mechanism 6, after the hole is opened, the linear slide rail 64 drives the hole cleaning pipe 61 to move along the X and Y axes, so that the hole cleaning pipe 61 moves directly below the newly opened hole, and the second cylinder 62 works to drive the hole cleaning pipe 61 to rise, so that the hole cleaning pipe 61 extends into the newly opened hole. During this process, the air extraction mechanism 7 works to generate suction at the strip-shaped hole 63, and when the strip-shaped hole 63 moves to the bottom area of the newly opened hole, the bottom of the circuit board can be subjected to dust suction treatment. After extending into the hole, dust suction treatment can be performed on the hole. The part of the strip-shaped hole 63 located at the upper part of the newly opened hole can perform surrounding dust suction treatment on the upper area of the newly opened hole, which can effectively perform dust and slag removal operations on the hole and the surrounding area of the hole;

[0075] By working of the first air extractor 71, the strip-shaped hole 63 generates suction. When the motor drives the rotary joint to rotate, the strip-shaped hole 63 can perform dust suction and slag removal operations on the hole wall of the newly opened hole and on the upper and bottom parts of the circuit board, which can effectively reduce the dust generated during hole opening adhering to the hole wall, affecting the processing quality of the subsequent process;

[0076] When the motor 13 is working, the hole cleaning pipe 61 is driven to rotate, and the rotation angle of the hole cleaning pipe 61 is set to ±180°, which can increase the dust suction range of the strip-shaped hole 63, and can comprehensively perform dust suction treatment on the hole wall of the newly opened hole;

[0077] The flexible pad 163 can increase the contact area of the connecting plate 162 and the hole cleaning pipe 61. When the hole cleaning pipe 61 rotates, the friction surface can be increased, so that the hole cleaning pipe 61 drives the connecting plate 162 to rotate, so that the brush head 161 cleans the hole wall;

[0078] When the second cylinder 62 drives the hole cleaning pipe 61 to extend into the newly opened hole, the material receiving groove 141 is attached to the bottom of the circuit board, and the brush head 161 is in contact with the hole wall. After the hole cleaning pipe 61 is attached to the flexible pad 163, the hole cleaning pipe 61 stops rising. When the motor drives the hole cleaning pipe 61 to rotate, the hole cleaning pipe 61 drives the connecting plate 162 to rotate through the flexible pad 163, so that the brush head 161 rotates to clean the hole wall. In cooperation with the suction force of the strip-shaped hole 63, the hole wall is cleaned by suction and brushing at the same time. The single action cannot effectively clean the residual materials in the hole, which can improve the cleaning quality and effectively avoid the influence of residual materials in the hole on the quality of subsequent production processes.

[0079] Through the use of the dust suction mechanism, when the second air extractor 26 is working, the dust suction nozzle 25 can suck the dust generated during the opening of the hole into the cyclone separator 27. When the cleaning device is inside, the dust on the base 1 can be cleaned into the table hole 29, and then the second air extractor 26 can suck the dust into the cyclone separator 27 for collection. The exhaust air can pass through the activated carbon net 28 for further filtration, reducing dust exhaust and purifying exhaust air, which can protect the working environment and workers, and facilitate workers to use the cleaning device.
