[0002] PCB, also known as printed circuit board, is an important support for electronic components. Drilling technology is required to connect different electronic components and fix the PCB itself. Due to the extremely complex drilling process, different components require different sized holes to be fixed. The hole size must be precise. Even a slight error can lead to huge losses.

[0003] In the prior art, a detachable carrier is provided on the carrier to support the circuit board.

At the same time, a variety of carriers need to be customized to adapt to circuit boards of different types and sizes, which increases costs. Summary of the Invention

DETAILED DESCRIPTION

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0031] For the sake of clarity, Figure 1 As shown, the X-axis direction is defined as the horizontal direction, the Y-axis direction is defined as the longitudinal direction, the X-axis and the Y-axis form a horizontal plane, and the Z-axis direction is defined as the up-down direction or the vertical direction.

[0032] like Figure 1-3 As shown, the present invention discloses a four-head shooting machine, including a workbench 1, a movable drilling mechanism 4 is provided above the middle of the workbench 1, the feeding end of the drilling mechanism 4 is connected to the feeding mechanism 2, and the discharging end of the drilling mechanism 4 is connected to the discharging mechanism 3, the drilling mechanism 4 includes a movable first carrier 41 and a movable second carrier 42 and a drilling assembly 5 installed on the first carrier 41 and the second carrier 42.

[0033] Specifically, the drilling mechanism 4 includes two first carriers 41 that can slide longitudinally on one side close to the feed end. The two first carriers 41 share the same set of slide rails. The bottoms of the two first carriers 41 are connected to independent motor-driven screw mechanisms, so that the two first carriers 41 can slide independently on the same set of slide rails. The top of each first carrier 41 is fixedly connected to a first fixed plate 411, and the drilling assembly 5 is fixedly connected above the first fixed plate 411. When in use, the first fixed plate 411 and the drilling assembly 5 above it can achieve longitudinal sliding through the first carrier 41.

[0034] Furthermore, the drilling mechanism 4 also includes two longitudinally slidable second carriers 42 on one side near the discharging end, the two second carriers 42 share the same set of slide rails, and the bottoms of the two second carriers 42 are connected with independent motor-driven screw mechanisms, so that the two second carriers 42 can slide independently on the same set of slide rails, and each second carrier 42 is movably connected with a transversely slidable second fixed plate 421 on the top, and each second fixed plate 421 is connected with a motor-driven screw mechanism at the bottom to make its sliding more precise, and the drilling assembly 5 is fixedly connected above the second fixed plate 421; when in use, the second fixed plate 421 and the drilling assembly 5 above it can achieve longitudinal sliding through the second carrier 42, and the drilling assembly 5 above the second fixed plate 421 can achieve transverse sliding through the second fixed plate 421, thereby realizing the sliding of the drilling assembly 5 above the second fixed plate 421 in the horizontal plane direction;

[0035] It should be noted that the two first carriers 41 drive the drilling assembly 5 above them to move longitudinally, so that circuit boards of different sizes can be adapted and the positions where holes need to be drilled can be accurately positioned longitudinally. At the same time, the two second carriers 42 drive the drilling assembly 5 above them to move longitudinally and transversely, so that the drilling position can be adjusted not only longitudinally but also transversely to adapt to more circuit board drilling needs, thereby improving the diversity and convenience of circuit board drilling, thereby solving the problem in the prior art that the layout of the detachable carrier needs to be readjusted according to the drilling positions on circuit boards of different sizes when drilling.

[0036] Furthermore, with the center line of the length direction of the slide rail shared by the two first platforms 41 as the dividing line, the sliding distance of the two first platforms 41 on their slide rails is half of the length of their slide rails; with the center line of the length direction of the slide rail shared by the two second platforms 42 as the dividing line, the sliding distance of the two second platforms 42 on their slide rails is half of the length of their slide rails.

[0037] like Figure 4-5As shown, specifically, the feeding mechanism 2 includes two first support plates 21 arranged symmetrically in the transverse direction, a plurality of first conveying rollers 22 arranged longitudinally, and a first driving motor 24. The two ends of the plurality of first conveying rollers 22 are movably connected to the two first support plates 21 arranged symmetrically. One end of the first conveying rollers 22 is provided with a first driven wheel 221, and each of the first driven wheels 221 is connected to the driving wheel of the first driving motor 24 through a first belt 23. When in use, the first driving motor 24 is started and drives the first belt 23 and the plurality of first driven wheels 221 to rotate through its driving wheel, thereby driving the plurality of first conveying rollers 22 to rotate; the top surfaces of the plurality of first conveying rollers 22 are combined to form a first conveying surface, on which a circuit board is placed, and the first conveying surface is used to convey the circuit board toward the drilling mechanism 4;

[0038] Furthermore, the first conveying rollers 22 are distributed at equal distances.

[0039] Specifically, the discharging mechanism 3 includes two second support plates 31 arranged symmetrically in the transverse direction, several second conveying rollers 32 arranged longitudinally and a second driving motor (not shown). The two ends of the several second conveying rollers 32 are movably connected to the two symmetrically arranged second support plates 31, and one end of the second conveying roller 32 is provided with a second driven wheel 321. Each second driven wheel 321 is connected to the driving wheel of the second driving motor through a second belt 33. When in use, the second driving motor starts and drives the second belt 33 and several second driven wheels 321 to rotate through its driving wheel, thereby driving several second conveying rollers 32 to rotate; the top surfaces of several second conveying rollers 32 are combined to form a second conveying surface, which is used to convey and discharge the circuit boards after being drilled by the drilling mechanism 4.

[0040] Furthermore, the plurality of second conveying rollers 32 are distributed at equal distances.

[0041] like Figure 2-3 As shown, specifically, a support frame 43 is movably connected to the slide rail shared by the two second carriers 42, and the support frame 43 is located between the two second carriers 42 and slides. A transverse support bar 431 is provided on the top of the support frame 43, and the support bar 431 provides guidance and support for the circuit board. When in use, when the circuit board is in the process of moving the drilling mechanism 4, the support bar 431 is located under the circuit board and plays a supporting role, preventing the circuit board from being deformed due to loss of support in the middle part of the drilling mechanism 4, which further causes drilling errors. At the same time, when the circuit board moves above the support bar 431, the support bar 431 also plays a guiding role, preventing the circuit board from longitudinally deviating during the movement, which causes drilling errors.

[0042] Furthermore, the top surface of the support bar 431 is on the same horizontal plane as the first conveying surface and the second conveying surface, so that there is no height difference when the circuit board moves between the feeding mechanism 2, the drilling mechanism 4 and the discharging mechanism 3.

[0043] like Figure 6-7 As shown, specifically, the drilling assembly 5 includes a bracket 51, a clamping assembly 52 and an electric drill 53, the bracket 51 includes a base 511, a first vertical plate 512, a support column 513 and a C-shaped bracket 514, the C-shaped bracket 514 includes an upper plate 5141 and a lower plate 5142, the lower plate 5142 is located below the upper plate 5141, and its length is greater than the length of the upper plate 5141, the free end of the lower plate 5142 is provided with a drill bit avoidance hole 5143 of the electric drill 53; the C-shaped bracket 514 is located above the base 511, the first vertical plate 512 is located between the C-shaped bracket 514 and the bottom 511, the first vertical plate One end of 512 is fixedly connected to the bottom of the C-shaped bracket 514, and the other end is fixedly connected to the top of the base 511. The two sides of the free end of the lower plate 5142 are respectively fixedly connected to the two sides of the base 511 through the two support columns 513, so that a first through hole (not shown) is formed between the two support columns 513. The electric drill 53 is installed at the bottom of the avoidance hole 5143, and the clamping assembly 52 is movably connected to the bottom of the C-shaped bracket 514. One end of the clamping assembly 52 passes through the first through hole and is clamped on the outer wall of the electric drill 53; the clamping assembly 52 can move in the horizontal, longitudinal and vertical directions, thereby driving the electric drill 53 to move synchronously.

[0044] Furthermore, the movable area of the drill bit of the electric drill 53 on the horizontal plane is smaller than the area of the avoidance hole 5143 and the two are coaxially corresponding; the top surface of the lower plate 5142 is on the same horizontal plane as the first conveying surface or the second conveying surface, so that there is no height difference when the circuit board moves between the feeding mechanism 2, the drilling mechanism 4 and the discharging mechanism 3.

[0045] Furthermore, the clamping assembly 52 includes a clamping portion 524 that can move in the vertical direction, an upper fixing assembly 521 that can slide laterally, a lower fixing assembly 522 that can slide longitudinally, and an L-shaped fixing block 523. The top of the upper fixing assembly 521 is slidably connected to the bottom of the lower plate 5142, and the bottom of the upper fixing assembly 521 is slidably connected to the top of the lower fixing assembly 522. The upper fixing assembly 521 and the lower fixing assembly 522 are respectively connected to independent motor-driven screw mechanisms. When in use, the upper fixing assembly 521 slides laterally under the drive of its motor-driven screw mechanism, driving the lower fixing assembly 522 to slide laterally synchronously; the lower fixing assembly 522 slides longitudinally under the drive of its motor-driven screw mechanism, thereby achieving The lower fixing assembly 522 now slides longitudinally and transversely in the horizontal plane direction; the lower fixing assembly 522 is fixedly connected to the L-shaped fixing block 523 on the side facing the electric drill 53, and the L-shaped fixing block 523 is movably connected to the clamping assembly 524 on the side close to the electric drill 53. The bottom of the L-shaped fixing block 523 is fixedly connected to the first cylinder 525, and the top rod of the first cylinder 525 passes through the L-shaped fixing plate 523 and is fixedly connected to the clamping part 524. The free end of the clamping assembly 524 is fixedly connected to the outer wall of the electric drill 53. When in use, the first cylinder 525 can drive the clamping part 524 to move in the vertical direction, thereby realizing the approach and distance between the electric drill 53 and the avoidance hole 5143.

[0046] It should be noted that, in addition to moving and positioning the drilling position on the circuit board by the drilling assembly 5 through the movement of the first carrier 41, the second carrier 42 and the second fixed plate 421, the position of the electric drill 53 can also be finely adjusted by the clamping assembly 52 to make the electric drill 53 more flexible, thereby achieving higher drilling accuracy in the drilling of the circuit board.

[0047] Furthermore, the bracket 51 also includes a second vertical plate 515, a top plate 516, an imaging mechanism 55 and a pressure plate mechanism 54. One end of the two second vertical plates 515 is fixedly connected to the two ends of the upper plate 5141, and the other end of the two second vertical plates 515 is fixedly connected to the top plate 516, so that a mounting position is formed between the top plate 516 and the C-shaped bracket 514. The pressure plate mechanism 54 is provided in the mounting position. A second through hole 5151 is provided on the second vertical plate 515 near the open end of the C-shaped bracket 514. One end of the pressure plate mechanism 54 passes through the second through hole 5151 and extends above the avoidance hole 5143. The imaging mechanism 55 is provided at one end of the top plate 516 near the avoidance hole 5143. The imaging mechanism 55 is coaxially corresponding to the avoidance hole 5143, and the imaging mechanism 55 includes an industrial camera.

[0048] Furthermore, the pressing plate mechanism 54 includes a second cylinder 543, a lever 541 and a fixing member 544. A fixing column 542 is provided on the top of the upper plate 5141. The fixing column 542 is hinged to the lever 541. The hinge is the fulcrum of the lever 541. One end of the lever 541 is connected to the second cylinder 543. The other end of the second cylinder 543 is connected to the bracket 51. The other end of the lever 541 passes through the second through hole 5151 and is fixedly connected to the fixing member 544. The bottom of the fixing member 544 is fixedly connected to a rubber pad 54 5. The rubber pad 545 and the fixing member 544 are provided with a third through hole 546 that is coaxial with and of the same size as the avoidance hole 5143, so that the drill bit of the electric drill 53 can sequentially pass through the avoidance hole 5143 and the third through hole 546 and extend upward, thereby achieving a drilling operation. During use, the circuit board is located between the lower plate 5142 and the rubber pad 545. The extension and retraction of the second cylinder 543 drives the lever 541 to swing up and down, thereby driving the fixing member 544 and the rubber pad 545 to move closer to and away from the circuit board, further achieving loosening and pressing fixation of the circuit board.

[0049] It should be noted that, in the conventional drilling method, a support is provided under the circuit board, and a drill bit avoidance hole is provided in the support, and the drill bit drills from the top to the bottom of the circuit board, so there is a risk of the circuit board being offset; in the present invention, the pressing plate mechanism 54, the clamping assembly 52 and the electric drill 53 in the drilling assembly 5 share a bracket; when drilling, the fixing part 544 and the rubber pad 545 on the pressing plate mechanism 54 first press and fix the circuit board, and then the clamping assembly 52 drives the drill bit of the electric drill 53 to pass through the avoidance hole 5143 and drill from the bottom of the circuit board to the top, which greatly improves the stability of drilling.

[0050] Specifically, the feeding mechanism 2 is also provided with a correction mechanism. When in use, if it is found that the placement position or direction of the circuit board on the first conveying surface is incorrect, the circuit board can be corrected by twice positioning the correction mechanism, thereby improving the accuracy of subsequent drilling; the correction mechanism includes a front gear rod 26 and a baffle 25. The front gear rod 26 can be moved in the vertical direction by a driving motor and is movably connected to the side of the feeding mechanism 2 close to the drilling mechanism 4. When the front gear rod 26 moves upward and blocks the first conveying surface, the circuit board on the first conveying surface moves toward the drilling mechanism 4 and is in contact with the front gear rod 26. The first conveyor roller 22 stops rotating at this time; the two baffles 25 are arranged in parallel between the two first support plates 21, and a third belt (not shown) is connected between the two baffles 25, and the third belt is connected to a driving mechanism. When in use, the driving mechanism drives the third belt to move, so that the two baffles 25 clamp toward the two sides of the circuit board, thereby controlling the distance between the circuit board and the first support plate 21, thereby achieving the second positioning; after the positioning is completed, the baffle 25 and the front gear rod 26 are reset to wait for the next positioning work.

[0051] Furthermore, when the two baffles 25 approach each other, they move relatively parallel to each other, and the setting direction of the front bar 26 is perpendicular to the setting direction of the baffles 25. The front bar 26 is set at the dividing line between the two first support plates 21.

[0052] like Figure 8-9 As shown, specifically, the workbench 1 is further provided with a laterally movable manipulator 6, which includes a laterally symmetrically arranged track 61, a longitudinally arranged beam 62, a vertically movable connection portion 63 and a plurality of suction cups 64, wherein both ends of the beam 63 are slidably connected to the two symmetrically arranged tracks 61, so that the beam 62 can move laterally along the track 61, and a connection portion 63 is provided on the beam 62, one end of the connection portion 63 is connected to the beam 62, and the other end is provided with a plurality of suction cups 64, and the connection portion 63 includes a third cylinder (not shown), which is driven by the third cylinder to make one side of the connection portion 63 move in the vertical direction, thereby driving the suction cup 64 to achieve vertical movement, and the disk surface of the suction cup 64 faces downward and has an adsorption effect on the circuit board. The manipulator 6 is also provided with a driving mechanism for moving it, and the automatic movement of the beam 62 is achieved by the driving mechanism;

[0053] Furthermore, the two manipulators 6 are symmetrically arranged on the outside of the feeding mechanism 2 and the discharging mechanism 3 with the drilling mechanism 4 as the dividing line, and the connecting parts 63 of the two manipulators 6 are relatively arranged. The suction cups 64 of the two manipulators 6 correspond to the positions of the first conveying surface and the second conveying surface respectively. When in use, driven by the driving mechanism, the beam 62 drives the suction cup 64 to move to the top of the circuit board, and moves downward through one side of the connecting part 63, so that the suction cup 64 contacts and adsorbs the circuit board, and then drives the circuit board to move again through the movement of the beam 62.

[0054] It should be noted that after the circuit board has been positioned for the second time by the correction mechanism, the first conveying roller 22 no longer rotates to convey the circuit board, but the manipulator 6 on the outside of the feeding mechanism 2 uses its suction cup 64 to adsorb the circuit board, and drives the circuit board to be moved into the drilling mechanism 4 through its crossbeam 62 and aligned with the drilling position; when the drilling of the circuit board is completed, the manipulator 6 on the outside of the discharging mechanism 3 uses its suction cup to adsorb the circuit board and moves the circuit board to the feeding mechanism 3, and at this time the second conveying roller 32 rotates to drive the circuit board to be discharged; the lateral movement of the circuit board is achieved through the mutual cooperation of the two manipulators 6, the feeding mechanism 2 and the discharging mechanism 3.

[0055] The working principle of the present invention is described in detail below:

[0056] The present invention is started after the power is turned on, and the first conveying roller 22 starts to rotate to form a movable first conveying surface. After the circuit board is placed on the first conveying surface, the circuit board moves horizontally on the first conveying surface until it contacts the front lever 26 raised from the bottom and cannot move further, thereby achieving the first positioning of the circuit board. At this time, the first conveying roller 22 stops rotating; then, the two baffles 25 next to the two first support columns 21 approach and clamp the two sides of the circuit board, and the position and direction of the circuit board are corrected by the clamping of the two baffles 25, thereby achieving the second positioning of the circuit board. After the circuit board positioning is completed, the baffles 25 and the front lever 26 are reset to wait for the next positioning work;

[0057] At this time, the manipulator 6 outside the feeding mechanism 2 starts working and moves to the top of the circuit board, uses its connecting part 63 to move down and uses the suction cup 64 to absorb the circuit board, and then moves the circuit board into the drilling mechanism 4 to align it with the drilling position. At this time, the support bar 431 is located under the circuit board and plays a supporting role. The four drilling components 5 of the drilling mechanism 4 move to the designated drilling positions respectively and fix the circuit board with its pressing plate mechanism 54. After the pressing plate is fixed, the electric drill 53 starts drilling from the bottom to the top of the circuit board;

[0058] After the current drilling is completed, the pressing plate mechanism 54 is lifted upward and away from the circuit board. Driven by the manipulator 6 on the outside of the feeding mechanism 2, the circuit board continues to move toward the discharge end until the next drilling position of the circuit board is aligned with the electric drill position of the drilling mechanism 4. After alignment, drilling is performed again. When all drilling work is completed on the circuit board, it is adsorbed by the manipulator 6 on the outside of the discharge mechanism 3 and moved to the feeding mechanism 3. The feeding mechanism 3 moves the circuit board out of the material through the second conveyor roller 32.

[0059] The inventive point of the present invention is that there are four carriers on the drilling mechanism that can drive the drilling assembly above it to slide independently, among which the two first carriers can move longitudinally, and the two second carriers can move longitudinally and transversely, so that circuit boards of different sizes can be moved to the corresponding drilling positions and the pressure plate drilling can be performed; at the same time, the pressure plate mechanism, clamping assembly and electric drill in the drilling assembly share a bracket. During the drilling process, after the pressure plate mechanism presses and fixes the circuit board, the electric drill on the drilling assembly starts to drill the circuit board from bottom to top, which greatly improves the stability and drilling accuracy of the circuit board during drilling, thereby reducing costs.
