Description

Technical Field

[0001] The present invention relates to the technical field of PCB board processing and positioning, and in particular to a PCB board drilling and positioning device and a PCB board drilling and positioning method. Background Art

[0002] Currently, two common positioning methods for PCB drilling are used in the industry: centering two pins and drilling the pin holes on the baseboard and then inserting the pins. The centering two pin method has certain drawbacks: after drilling, a dedicated machine is required to remove the pins. This method consumes labor and equipment costs. The other method, drilling the pin holes on the baseboard and then inserting the pins, requires drilling the pin holes again on the backing board when changing PCB models. Repeated drilling of the backing board can cause the pin holes to intersect, making positioning impossible. In this case, the pin holes must be re-positioned and the backing board must be replaced after a certain period of time. This method consumes a lot of time and cost. Changing part numbers can take 15 to 25 minutes, making the process extremely cumbersome and reducing production efficiency.

[0060] A longitudinal motor (not shown in the figure) is provided inside the machine 1, and threaded transmission rods (not shown in the figure) are connected to both sides of the axis block 107. The spiral directions of the threaded transmission rods on both sides of the axis block 107 are opposite. The threaded transmission rods are connected to the axis block 107 by bearings, and the contact portion with the axis block 107 has no circumferential side threads. The axial direction of the threaded transmission rod is the same as the extension direction of the longitudinal sliding groove 101. One end of the threaded transmission rod is connected to the inner wall bearing of the machine 1, and the other end is connected to the output end of the longitudinal motor; the threaded connection port 303 is located at the longitudinal At the bottom of the groove of the sliding seat 301, a thread is provided inside which is connected to the threaded transmission rod. The two longitudinal sliding seats 301 distributed inside the two longitudinal sliding grooves 101 are respectively connected to the two sides of the threaded transmission rod, and the threads on both sides are opposite. The side longitudinal sliding seat 301 runs synchronously inside the longitudinal sliding groove 101, so that the length of the synchronized moving distance can be compared with the collected data of the infrared rangefinder 105 inside the left horizontal sliding groove 102, and the radius of the rectangular inscribed circle of the PCB board can be calculated. The running distance of the longitudinal sliding seat 301 is adjusted by the radius, thereby automatically adapting to the needs of various PCB boards.

[0061] The two longitudinal sliding seats 301 are respectively connected to the threaded transmission rod in opposite directions, and the midpoint of the connection line between the two longitudinal sliding seats 301 is at the same position as the midpoint of the axis block 107 .

[0062] Please refer to Figure 1-5 ,

[0063] A PIN positioning slot is provided above the longitudinal sliding seat 301 to cooperate with the PIN needle mechanism. The PIN needle mechanism includes an inner guide box 304 and an outer adjustment box 305 installed at the bottom of the PIN positioning slot.

[0064] The inner guide box 304 includes an inner disc cavity 307 at the bottom, an adjusting gear 306 is disposed inside the inner disc cavity 307, and the rotating circular edge of the adjusting gear 306 extends out of both sides of the inner guide box 304;

[0065] The outer adjustment box 305 is located above the inner guide box 304. Two side plates of different lengths are provided on both sides of the outer adjustment box 305. The two side plates are respectively located on both sides of the inner guide box 304. A long-side linear tooth-shaped groove 308 is provided on the inner side of the longer side plate.

[0069] In yet another embodiment of the present invention:

[0070] Please refer to Figure 1-3 The horizontal clamping group 2 includes an electric drive base 201 and a lifting cylinder 203; the lifting cylinder 203 is used to match the thickness of different PCB boards, and at the same time assists the movable pressing block 208 to adjust the static friction and press down;

[0071] Each of the left side transverse sliding groove 102 and the right side transverse sliding groove 103 has a linear sliding groove 104 therein;

[0072] The electric drive base 201 is slidably connected to the electric drive base 201, and a transmission square seat 202 is provided between the electric drive base 201 and the lifting cylinder 203. The transmission square seat 202 cooperates with the left horizontal sliding groove 102 and the right horizontal sliding groove 103. The output end of the lifting cylinder 203 is upward and is provided with a lifting seat 204. A linkage plate 205 is provided on the side of the lifting seat 204 close to the axis block 107;

[0073] The two transverse clamping groups 2 connected to the left transverse sliding groove 102 are connected to the same linkage plate 205 ; the two transverse clamping groups 2 connected to the right transverse sliding groove 103 are connected to the same linkage plate 205 .

[0074] Please pay attention to Figure 1-4 A driving motor 209 is provided on the side of the midpoint of the single linkage plate 205 away from the axis block 107, and the output end of the driving motor 209 is connected to the extended connecting block 210;

[0075] Two built-in movable connection ports 206 are provided below the two sides of the single linkage plate 205. A front connection block 207 is movably connected inside the built-in movable connection port 206. A movable pressing block 208 is movably connected below the two front connection blocks 207. A single movable pressing block 208 connects two adjacent front connection blocks 207.

[0076] A connecting post 211 is provided on one side of the movable pressure block 208 close to the lifting cylinder 203 , and the connecting post 211 is movably connected to the end of the extended connecting block 210 away from the driving motor 209 ;

[0077] A radar rangefinder 212 is embedded on the upper surface of the lifting cylinder 203. The detection direction of the radar rangefinder 212 is parallel to the extension direction of the lifting cylinder 203. The bottom of the movable pressure block 208 is a rubber pressure block.

[0078] The clamping method of the horizontal clamping group 2 is as follows: the electric-controlled driving base 201 moves along the direction of the linear slide 104, and the driving speed of the two electric-controlled driving bases 201 on the same side is the same. During the movement, the lifting cylinder 203 drives the lifting seat 204 to rise, driving the driving motor 209 to perform a fixed-angle deflection movement. The lowest point of the deflection movement running circle of the driving motor 209 is the same as the lowest point of the lifting cylinder 203. The deflection angle of the driving motor 209 is greater than 90 degrees, and its highest point is the bottom edge of the front connecting block 207. The driving motor 209 connected to the left horizontal sliding groove 102 and the driving motor 209 connected to the right horizontal sliding groove 103 are arranged opposite to each other, and their rotation directions are the same;

[0079] When the driving motor 209 is yawed, the rubber part at the bottom of the movable pressure block 208 will come into frictional contact with the upper surface of the PCB board. Since the two motors rotate in the same direction, they will generate two opposite forces on the upper surface of the PCB board, causing the PCB board to rotate and adjust. When the side edges of the PCB board are in contact with the outer walls of the four lifting cylinders 203, that is, the lifting cylinders 203 cannot move the movable pressure block 208 and cannot continue to rotate to generate force on the PCB board, it stops operating. In this process, the driving motor 209 and the movable pressure block 208 continue to reciprocate, and by cooperating with the lifting action of the lifting cylinder 203, the movable pressure block 208 maintains pressure on the PCB board while stopping the movement of the electronically controlled driving base 201. At this time, the PIN hole is positioned by adjusting the vertical PIN positioning group.

[0080] Please pay attention to Figure 2 、 Figure 3 An infrared rangefinder 105 is provided at one end of the single linear slide 104 away from the axis block 107. The ranging direction of the infrared rangefinder 105 is the same as the running direction of the linear slide 104. The infrared rangefinder 105 obtains the movement distance data and change data of the electronically controlled drive base 201 through observation, so as to judge whether it is necessary to turn off the power of the electronically controlled drive base 201, that is, when clamping the two sides, the positions of the four lifting cylinders 203 cannot move, and the observation data remains unchanged. At the same time, it can cooperate with the radar rangefinder 212 to obtain the PCB board thickness data, so as to judge whether to continue to operate the drive motor 209.

[0081] A method for quickly positioning a PCB hole by drilling a hole comprises the following steps:

[0082] S1. Place the PCB board vertically on the machine 1 and push the PCB board to the center of the machine 1 by adjusting the single-side horizontal clamping group 2 step by step. At this time, the PCB board is only adjusted to the center of the machine 1 to meet the processing requirements of PCB boards of different specifications.

[0083] S2. Use infrared to locate the moving distance of the electronically controlled driving base 201 in the left and right transverse sliding slots 102 and 103. Drive and adjust the distance between the two sides to the same position, and synchronously drive the PCB to move so that the center line of the PCB intersects with the axis block 107 on the machine 1. Calculate the infrared distance data on both sides and move the PCB to the center position in a clamping manner.

[0084] S3, start the lifting cylinder 203 to extend and start the drive motor 209, so that the movable pressing block 208 drives the PCB board to rotate back and forth, and then slowly retract the lifting cylinder 203;

[0085] S4. Start the longitudinal motor to drive the two vertical PIN positioning groups to move to the bottom of the PCB board, release the electric telescopic cylinder 311, so that the PIN pins pop out and contact the ground of the PCB board;

[0086] S5. Rotate the adjustment gear 306 to enable the external adjustment box 305 to perform corresponding axial adjustment. When the PIN pins on both sides are in contact with the original positioning holes on the PCB board, the PIN pins are automatically ejected to limit the hole position. At this time, the PCB board is in a positioned and clamped state, and the drilling operation on the drill platform can be carried out.

[0087] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components.
