[0001] The utility model relates to the technical field of PCB processing, in particular to an adjustable board taking device and circuit board taking and placing equipment. Background Art

[0002] There are more and more holes on the existing circuit boards. When there are many holes, the suction cup structure on the adjustable board removal device may break the vacuum, resulting in the inability to firmly suck the board, causing the board to fail to be sucked up or fall off during transportation. Now the equipment is all automated, and there are almost no people guarding the machine. If the board cannot be sucked up or falls off, it needs to be handled manually, which seriously affects the processing efficiency and increases the failure rate of the equipment. Therefore, designing an adjustable board removal device that can prevent the failure of sucking or falling of the board has become an urgent problem to be solved. Utility Model Content

[0008] The first clamping member is used to extend into the gap to clamp the circuit board, and drive the circuit board to move to enlarge the gap, so that the second clamping member can smoothly extend into the gap and clamp the circuit board.

[0009] Optionally, the board rack includes a baffle and a baffle rod, the baffle is inclined relative to a horizontal plane, the baffle rod is connected to the baffle and extends in a direction perpendicular to the baffle, there are multiple circuit boards, and the multiple circuit boards are stacked on the baffle rod relying on the baffle.

[0013] Optionally, the clamping mechanism also includes a sensing device, which includes a sensor and a trigger member. The end of the movable rod away from the mounting member is connected to the trigger member. The sensor is installed on the fixed frame corresponding to the trigger member. The movable rod is used to drive the trigger member to move to trigger the sensor.

[0014] Optionally, the first clamping member is movably mounted on the fixed frame, and when the adsorption mechanism drives the circuit board to leave an escape space for the first clamping member, the first clamping member moves toward the circuit board, and after clamping the circuit board, moves toward the direction away from the board frame to leave an escape space for the second clamping member.

[0015] Optionally, the clamping mechanism also includes two sliding members, which are respectively slidably connected to the two fixed frames, and each of the sliding members is connected to two second clamping members at one end close to the circuit board.

When the gap becomes large enough to accommodate the second clamping member, the second clamping member smoothly extends into the gap to clamp the circuit board. From the above, it can be seen that the suction force required for flipping the tilted circuit board is smaller than the suction force required for directly sucking the circuit board off the board rack, making it easier for the adsorption mechanism to suck up the circuit board. Through multi-point clamping by the first clamping member and the second clamping member, it can be ensured that the circuit board is subjected to uniform force, preventing its deformation and breakage, and improving the stability and safety of the handling process.

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0037] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0038] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0039] The utility model provides an adjustable plate taking device 1.

[0040] Reference Figures 1 to 5 The adjustable board-taking device 1 comprises a board rack 100, a clamping mechanism 200 and an adsorption mechanism 300. The circuit board 600 is a conventional PCB board. The circuit board 600 is tilted on the board rack 100, that is, there is a certain angle between the board surface of the circuit board 600 and the horizontal plane; the clamping mechanism 200 comprises a first clamping member 210 and a second clamping member 220. The adsorption mechanism 300 is used to adsorb the circuit board 600 located on the outermost layer of the board rack 100, and drive the circuit board 600 to flip and form a gap with the adjacent circuit board 600, or drive the circuit board 600 to flip and form a gap with the board rack 100. The formed gaps are all used as avoidance spaces for the first clamping member 210 to clamp. The first clamping member 210 can smoothly clamp the circuit board 600, and the first clamping member 210 drives the circuit board 600 to continue to move to enlarge the gap. When the gap becomes large enough to accommodate the second clamping member 220, the second clamping member 220 smoothly extends into the gap to clamp the circuit board 600. As can be seen from the above, the suction force required when the tilted circuit board 600 is flipped is smaller than the suction force required to directly suck the circuit board 600 off the board rack 100, making it easier for the adsorption mechanism 300 to suck up the circuit board 600. Through multi-point clamping by the first clamping member 210 and the second clamping member 220, it can be ensured that the circuit board 600 is evenly stressed, preventing its deformation and breakage, thereby improving the stability and safety of the transportation process.

[0041] Optionally, the board rack 100 includes a baffle 110 and a baffle rod 120, the baffle 110 is inclined relative to the horizontal plane, the baffle rod 120 is connected to the baffle 110 and extends in a direction perpendicular to the baffle 110, the number of circuit boards 600 is multiple, and the multiple circuit boards 600 are stacked on the baffle rod 120 relying on the baffle 110.

[0042] like Figure 1As shown, in one embodiment of the present invention, the plate rack 100 includes a baffle 110 and a baffle rod 120. Specifically, the baffle 110 is inclined relative to the horizontal plane, and the baffle rod 120 is connected to the bottom end of the baffle 110 and extends in a direction perpendicular to the baffle 110. Figure 3 and Figure 4 As shown, the baffle 110 and the baffle rod 120 are connected to form an inclined L-shaped structure, and multiple circuit boards 600 are stacked on the board rack 100. The edge of the bottom of each circuit board 600 abuts against the baffle rod 120, and the circuit board 600 located in the innermost layer is supported by the baffle 110. The adsorption mechanism 300 adsorbs and flips the circuit board 600 located in the outermost layer in turn to leave escape space for the clamping mechanism 200; it can be seen from the above that by setting the baffle 110 and the baffle rod 120, it is beneficial to place multiple circuit boards 600 on the board rack 100, and the baffle 110 is inclined to make the suction force required by the adsorption mechanism 300 to absorb the circuit board 600 relatively small, which can avoid the situation where it cannot be sucked up.

[0043] Optionally, the adjustable plate removing device 1 also includes a supporting assembly 400, which includes a bracket 410, which is extended along the length direction of the circuit board 600, and fixed frames 420 are respectively installed at both ends of the bracket 410. Each fixed frame 420 is installed with an adsorption mechanism 300, a first clamping member 210 and a second clamping member 220. A connecting member 430 is also provided on the bracket 410 for connecting to a six-axis robot arm.

[0044] like Figure 5 As shown, in one embodiment of the utility model, the adjustable plate-taking device 1 also includes a support assembly 400 for connecting the adsorption mechanism 300 and the clamping mechanism 200, and the support assembly 400 includes a bracket 410 extending along the length direction of the circuit board 600, and a fixing frame 420 is installed at both ends of the bracket 410, and each fixing frame 420 is installed with an adsorption mechanism 300, a first clamping member 210 and a second clamping member 220 for adsorbing and clamping the two side edges of the circuit board 600, and a connecting member 430 is installed on the bracket 410, and the connecting member 430 is used to connect to a six-axis robot arm (not shown), and the six-axis robot arm is connected to the circuit board 600. The dynamic support assembly 400 moves, so that the adsorption mechanism 300 and the clamping mechanism 200 move along with the support assembly 400. The six-axis robot arm first drives the adsorption mechanism 300 to absorb the surface of the circuit board 600, and then flips it. After the first clamping member 210 clamps the circuit board 600, the six-axis robot arm lifts the circuit board 600 to leave escape space for the second clamping member 220. After the second clamping member 220 clamps the circuit board 600, the six-axis robot arm continues to carry it. It can be understood that each joint of the six-axis robot arm can rotate independently, thereby realizing diversified movements and having flexible operation capabilities to improve the automation level of the adjustable plate taking device 1.

[0045] Optionally, the adsorption mechanism 300 includes two mounting members 310 and a plurality of suction nozzles 320 , the two mounting members 310 are respectively connected to two fixing frames 420 , and the plurality of suction nozzles 320 are disposed on the two mounting members 310 corresponding to the circuit boards 600 and arranged along the width direction of the circuit boards 600 .

[0046] like Figure 5 As shown, in one embodiment of the utility model, the adsorption mechanism 300 includes two mounting members 310 and a plurality of suction nozzles 320. Specifically, two mounting members 310 are respectively connected to the two fixing frames 420, and the two mounting members 310 are extended along the width direction of the circuit board 600. A plurality of suction nozzles 320 are installed on a side of each mounting member 310 close to the circuit board 600, and the plurality of suction nozzles 320 are also arranged along the width direction of the circuit board 600. It can be understood that at least some of the suction nozzles 320 can avoid the plurality of openings on the circuit board 600 to prevent the suction nozzles 320 from breaking the vacuum and failing to absorb the circuit board 600. It should be noted that the plurality of suction nozzles 320 can be arranged in sections to adapt to circuit boards 600 of different widths; and the arrangement of the suction nozzles 320 can be set according to actual needs, and no specific limitation is made here.

[0047] Optionally, the support assembly 400 also includes a movable rod 422, one end of the movable rod 422 is connected to the mounting member 310, the other end of the movable rod 422 is movably passed through the fixed frame 420, and an elastic member 424 is sleeved on the movable rod 422, one end of the elastic member 424 abuts the mounting member 310, and the other end of the elastic member 424 abuts the fixed frame 420.

[0048] like Figure 7As shown, in order to prevent the circuit board 600 from being crushed during the board removal process, in one embodiment of the utility model, the mounting member 310 is fixedly connected to one end of the movable rod 422, and a sleeve 421 is installed on the fixing frame 420, and the other end of the movable rod 422 is movable through the sleeve 421 and connected to the limit block 423, and the limit block 423 is used to prevent the movable rod 422 from being separated from the sleeve 421, and the elastic member 424 is usually a spring, which is sleeved on the movable rod 422 and abuts the mounting member 310 at one end and the sleeve 421 at the other end. In the initial state, the spring is in a compressed state, and the mounting member 310 and the fixing frame 420 are moved away from each other by the elastic force of the spring; a guide groove 311 is also provided on the corresponding sleeve on the mounting member 310; when taking the board, the six-axis robot arm drives the suction nozzle 320 to the direction close to the circuit board 600 Move, the suction nozzle 320 contacts the circuit board 600, and the six-axis robot arm continues to move to make the sleeve 421 further compress the elastic part 424, and the suction nozzle 320 presses the board surface of the circuit board 600, and the end of the sleeve 421 close to the mounting part 310 extends into the guide groove 311, and the end of the movable rod 422 away from the mounting part 310 drives the limit block 423 away from the fixing frame 420; when the six-axis robot arm drives the circuit board 600 to flip, the elastic part 424 rebounds to make the mounting part 310 away from the fixing frame 420, and the movable rod 422 drives the limit block 423 to move in the direction close to the fixing frame 420. It can be seen from the above that in the process of the suction nozzle 320 contacting and flipping the circuit board 600, the elastic part 424 and the movable rod 422 can play a buffering role to prevent the circuit board 600 from being crushed during the suction of the robot arm, thereby improving the safety of the equipment.

[0049] Optionally, the clamping mechanism 200 also includes a sensing device 230, which includes a sensor 231 and a trigger member 232. The end of the movable rod 422 away from the mounting member 310 is connected to the trigger member 232. The sensor 231 is installed on the fixed frame 420 corresponding to the trigger member 232. The movable rod 422 is used to drive the trigger member 232 to move to trigger the sensor 231.

[0050] like Figure 7As shown, in one embodiment of the utility model, the clamping mechanism 200 detects whether the suction nozzle 320 adsorbs the circuit board 600 through the sensing device 230. Specifically, the sensing device 230 includes a sensor 231 and a trigger member 232. The trigger member 232 is connected to the side of the limit block 423 away from the sleeve 421. The position corresponding to the trigger member 232 on the fixed frame 420 is provided with a sensor 231. The trigger member 232 is generally a metal member. When the six-axis robot arm drives the suction nozzle 320 to move in a direction close to the circuit board 600, the suction nozzle 320 contacts the circuit board 600, and the six-axis robot arm continues to move in the previous direction. The elastic member 424 When compressed, the movable rod 422 drives the limit block 423 and the trigger member 232 away from the sensor 231. When the trigger member 232 moves away from the sensor 231 to a preset distance, the sensor 231 is triggered. At this time, the suction nozzle 320 sucks the circuit board 600, and the six-axis robot arm stops driving the suction nozzle 320 to move toward the direction close to the circuit board 600. It can be seen from the above that by setting the sensing device 230, the adsorption mechanism 300 and the clamping mechanism 200 can be directly driven to move by the six-axis robot arm. By setting the sensing device 230, the moving distance of the six-axis robot arm can be accurately controlled without pre-measurement, thereby avoiding damage to the circuit board 600 and increasing the handling efficiency.

[0051] Optionally, the first clamping member 210 is movably mounted on the fixing frame 420. When the adsorption mechanism 300 drives the circuit board 600 to leave an escape space for the first clamping member 210, the first clamping member 210 moves toward the circuit board 600, and after clamping the circuit board 600, moves toward the direction away from the board frame 100 to leave an escape space for the second clamping member 220.

[0052] like Figure 5 and Figure 6As shown, in one embodiment of the utility model, the first clamping member 210 is connected to the first cylinder 250. By controlling the first cylinder 250, the first clamping member 210 can be extended and rotated to clamp the circuit board 600. The second cylinder 260 is installed on the fixing frame 420. The end of the first cylinder 250 away from the first clamping member 210 is connected to the second cylinder 260. By controlling the extension and contraction of the second cylinder 260, the first cylinder 250 and the first clamping member 210 can be driven to move in a direction close to or away from the circuit board 600. When adsorption is required, the second cylinder 260 drives the first cylinder 250 and the first clamping member 210 away from the circuit board 600. After the suction nozzle 320 successfully adsorbs the circuit board 600, the six-axis robot arm drives the circuit board 600 to flip over and give the first clamping member 21 0 leaves an avoidance space, the second cylinder 260 drives the first cylinder 250 and the first clamping member 210 to move towards the direction close to the circuit board 600. At this time, when the first cylinder 250 drives the first clamping member 210 to rotate so that the circuit board 600 enters the clamping position, the first cylinder 250 contracts, and the first cylinder 250 is also equipped with a clamping head 280 at the position close to the first clamping member 210. The first clamping member 210 moves to cooperate with the clamping head 280 to clamp the circuit board 600, and the six-axis robot drives the sucked circuit board 600 away from the adjacent circuit board 600 on the plate rack 100 to leave an avoidance space for the second clamping member 220; by arranging the first cylinder 250 and the second cylinder 260, the first clamping member 210 does not cause interference during the adsorption process, and the circuit board 600 can be clamped smoothly.

[0053] Optionally, the clamping mechanism 200 also includes two sliding members 240, which are respectively slidably connected to the two fixed frames 420, and each sliding member 240 is connected to two second clamping members 220 at one end close to the circuit board 600. After the first clamping member 210 drives the circuit board 600 to leave avoidance space for the second clamping member 220, the second clamping member 220 is used to move toward the direction close to the circuit board 600 to clamp and carry the circuit board 600.

[0054] like Figure 5 and Figure 6As shown, in one embodiment of the utility model, the clamping mechanism 200 also includes two sliding members 240 for connecting the second clamping member 220. Specifically, the two sliding members 240 are slidably connected to the two fixing frames 420 through two third cylinders 270 respectively. The third cylinder 270 can drive the sliding member 240 to move in a direction close to or away from the circuit board 600. One end of each sliding member 240 close to the circuit board 600 is connected to two first cylinders 250. The output end of each first cylinder 250 is connected to the second clamping member 220. The first cylinder 250 can drive the second clamping member 220 to move and rotate to clamp the circuit board 600. When the circuit board 600 is adsorbed by the suction nozzle 320, the third cylinder 270 drives the sliding member 240 away from the circuit board 600. When the first clamping member 210 clamps the circuit board 600 and lifts the circuit board 600 , and after leaving an escape space for the second clamping member 220, the third cylinder 270 drives the sliding member 240 to move in the direction close to the circuit board 600. After moving into place, the first cylinder 250 drives the second clamping member 220 to rotate so that the circuit board 600 enters the clamping position, and the first cylinder 250 contracts to move the second clamping member 220 and cooperate with the clamp 280 to clamp the circuit board 600; it can be understood that by setting the third cylinder 270, the second clamping member 220 does not cause interference during the clamping process; the two second clamping members 220 are arranged on both sides of the first clamping member 210. When clamping, the circuit board 600 has six force points in the width direction, and they are symmetrically arranged along the two sides of the circuit board 600, so that the circuit board 600 can be evenly stressed, preventing the circuit board 600 from being deformed or broken during transportation due to its excessive size, so as to improve the safety of the transportation process.

[0055] Optionally, the support assembly 400 also includes a guide rail 440, and the guide rail 440 is set on the bracket 410 along the width direction of the circuit board 600, wherein one fixing frame 420 is fixedly connected to one end of the bracket 410, and the other fixing frame 420 is slidably installed on the guide rail 440 so that the distance between the two fixing frames 420 is adjustable.

[0056] like Figure 5As shown, in one embodiment of the utility model, the spacing between the two fixing frames 420 on the bracket 410 is adjustable. Specifically, a guide rail 440 is provided on the bracket 410 along the width direction of the circuit board 600, wherein one of the fixing frames 420 is fixedly connected to one end of the bracket 410, wherein the other fixing frame 420 is slidably installed on the guide rail 440, and the bracket 410 is also provided with a motor 510, an adjustment screw rod 520 and a screw rod nut seat 530, the screw rod nut seat 530 is connected to the fixing frame 420 on the guide rail 440, one end of the adjustment screw rod 520 is connected to the output end of the motor 510, and the other end of the adjustment screw rod 520 is rotatably connected to the screw rod nut seat 530, and the operation of the motor 510 drives the fixing frame 420 to move along the guide rail 440, so that the spacing between the two fixing frames 420 is adjustable; when the circuit board 600 is placed on the plate rack 100, it can correspond to The fixing frame 420 fixedly connected to the bracket 410 positions and places the circuit board 600. After the circuit board 600 is positioned and placed, the motor 510 adjusts the movement of the fixing frame 420 on the guide rail 440 so that the first clamping member 210 and the second clamping member 220 at both ends and the suction nozzle 320 are moved to appropriate positions on both sides of the circuit board 600 for adsorption and clamping; it can be seen from the above that by setting a sliding fixing frame 420, the clamping mechanism 200 can adapt to circuit boards 600 of different sizes, thereby improving applicability; it should be noted that, in some other embodiments of the utility model, the two fixing frames 420 can be respectively connected to two guide rails 440, the motor 510, the adjusting screw rod 520 and the screw rod nut seat 530 to adapt to the situation where the circuit board 600 is not positioned and placed on the board rack 100, and adaptive adjustments can be made according to specific circumstances, and no specific limitations are made here.

[0057] The utility model also proposes a circuit board picking and placing device, which includes an adjustable board picking device 1. The specific structure of the adjustable board picking device 1 refers to the above embodiment.
