Description

Technical Field

[0001] The utility model relates to the technical field of circuit board production equipment, in particular to a device for separating a circuit board from a pad. Background Art

[0002] In the drilling process of circuit boards, at least two circuit boards are stacked on a pad. The pad transports the stacked circuit boards to a drilling machine, which drills the stacked circuit boards. Since the drill bit of the drilling machine has to drill through the circuit boards, it is inevitable that the drill bit of the drilling machine will drill into the pad, and the burrs on the edge of the holes produced by the circuit boards after drilling will extend into the pad, making it difficult to separate the stacked circuit boards from the pad. Moreover, since a vacuum is easily generated between the circuit boards and the pad, it is even more difficult to separate the circuit boards from the pad. Because the stacked circuit boards are flat against the pad, the circuit boards can only be sucked away one by one by a suction cup robot, and it is difficult to remove the entire stack of stacked circuit boards at one time. Therefore, the defects are very obvious, and a solution is urgently needed. Utility Model Content

[0003] In order to solve the above technical problems, the purpose of the present utility model is to provide a device for separating a circuit board and a pad.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A device for separating a circuit board and a pad, which includes a machine platform, a lifting drive mechanism installed on the machine platform, a lifting plate installed on the lifting end of the lifting drive mechanism, and two suction modules respectively arranged at both ends of the lifting plate. The top surface of the machine platform is provided with a bearing surface for supporting the pad, the two suction modules are located on both sides of the bearing surface, a lifting cavity is provided in the middle of the machine platform, the lifting plate horizontally passes through the lifting cavity and is lifted and lowered in the lifting cavity, the suction module includes a mounting plate arranged on the lifting plate and multiple suction cups installed on the mounting plate, and the multiple suction cups are arranged in a straight line.

[0006] Furthermore, the lifting drive mechanism is located in the lifting cavity.

[0007] Furthermore, the mounting plate is provided with a slider, the slider is slidably connected to the lifting plate, and the slider is locked on the lifting plate via a locking piece.

[0008] Furthermore, each suction cup is connected to the mounting plate via an adjustment block.

[0009] Furthermore, the adjusting block is slidably connected to the mounting plate, and the adjusting block is locked on the mounting plate via a locking member.

[0010] Furthermore, the lifting plate and the mounting plate are arranged vertically.

[0011] Furthermore, the lifting drive mechanism includes a fixed plate installed on the inner wall of the lifting chamber and a cylinder installed on the fixed plate, and the lifting plate is installed on the piston rod of the cylinder.

[0012] Furthermore, the mounting plate is equipped with a sensor.

[0013] The beneficial effects of the present invention are as follows: in actual application, a pad with a certain flexibility carries at least two stacked circuit boards, and a drilling machine drills holes in the circuit boards carried by the pad. Since the drill bit of the drilling machine needs to drill through the circuit boards, the drill bit of the drilling machine will inevitably drill into the pad, causing burrs generated after drilling the circuit boards to extend into the pad or it will be difficult to separate the circuit boards from the pad due to vacuum generated between the circuit boards. In order to facilitate the separation of the pad from the circuit boards, the pad transports the drilled circuit boards to the machine, and the carrying surface of the machine carries the pad, with both ends of the pad extending out of the carrying surface respectively, and the two suction modules are respectively located on the pad At the bottom, the lifting drive mechanism drives the lifting plate and the two suction modules to rise until the suction cups of the two suction modules respectively contact the bottom surface of the pad and suck the pad. Then the lifting drive mechanism drives the lifting plate and the two suction modules to descend. The suction cups of the two descending suction modules suck the two ends of the pad and pull it downward, so that the two ends of the pad are bent downward to form a certain arc. The two ends of the pad are separated from the two ends of the circuit board, which can not only break the vacuum between the pad and the circuit board, but also form a clamping space for the clamping end of the external clamping manipulator to extend into. At this time, the external clamping manipulator can clamp the two ends of the stacked circuit boards to clamp the stacked circuit boards away. The utility model has a simple structure and low cost, and can quickly separate the pad from the circuit board, so that the external clamping manipulator can clamp the entire stack of stacked circuit boards away.

[0019] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0020] like Figures 1 to 3 As shown, the utility model provides a circuit board and pad separation device, which includes a machine 1, a lifting drive mechanism 2 installed on the machine 1, a lifting plate 3 installed on the lifting end of the lifting drive mechanism 2, and two suction modules 4 respectively arranged at both ends of the lifting plate 3. The top surface of the machine 1 is provided with a bearing surface 5 for bearing the pad 14. The two suction modules 4 are located on both sides of the bearing surface 5. A lifting cavity 6 is provided in the middle of the machine 1. The lifting plate 3 horizontally passes through the lifting cavity 6 and is lifted and lowered in the lifting cavity 6. The suction module 4 includes a mounting plate 7 arranged on the lifting plate 3 and a plurality of suction cups 8 installed on the mounting plate 7. The plurality of suction cups 8 are arranged in a straight line.

[0021] In actual application, the pad 14 with a certain flexibility carries at least two stacked circuit boards 15, and the drilling machine drills holes in the circuit boards 15 carried by the pad 14. Since the drill bit of the drilling machine needs to drill through the circuit boards 15, the drill bit of the drilling machine will inevitably drill into the pad 14, so that the burrs generated after the circuit boards 15 are drilled extend into the pad 14 or the circuit boards 15 are difficult to separate from the pad 14 due to the vacuum generated between the pad 14 and the pad 14; in order to facilitate the separation of the pad 14 from the circuit boards 15, the pad 14 transports the drilled circuit boards 15 to the machine 1, and the carrying surface 5 of the machine 1 supports the pad 14, and the two ends of the pad 14 extend out of the carrying surface 5 respectively, and the two suction modules 4 are respectively located on the pad 14. , at this time, the lifting drive mechanism 2 drives the lifting plate 3 and the two suction modules 4 to rise until the suction cups 8 of the two suction modules 4 respectively contact the bottom surface of the pad 14 and suck the pad 14, then the lifting drive mechanism 2 drives the lifting plate 3 and the two suction modules 4 to descend, and the suction cups 8 of the two descending suction modules 4 suck the two ends of the pad 14 and pull it downward, so that the two ends of the pad 14 are bent downward to form a certain arc, and the two ends of the pad 14 are separated from the two ends of the circuit board 15, which can not only break the vacuum between the pad 14 and the circuit board 15, but also form a clamping space for the clamping end of the external clamping manipulator to extend into. At this time, the external clamping manipulator can clamp the two ends of the stacked circuit boards 15 to clamp the stacked circuit boards 15 away. The utility model has a simple structure and low cost, can quickly separate the pad 14 from the circuit board 15, and enables the external clamping manipulator to clamp the entire stack of stacked circuit boards 15 away.

[0022] In this embodiment, the lifting drive mechanism 2 is located in the lifting cavity 6. This structural design makes the structure of the platform 1 and the lifting drive mechanism 2 compact, and prevents the lifting drive mechanism 2 from being exposed outside the platform 1, thereby providing a certain degree of protection for the lifting drive mechanism 2.

[0023] In this embodiment, the mounting plate 7 is equipped with a slider 9, which is slidably connected to the lifting plate 3. The slider 9 is locked to the lifting plate 3 via a locking member; specifically, the locking member is a bolt. Loosening the locking member allows the slider 9 to slide relative to the lifting plate 3, thereby adjusting the position of the mounting plate 7 and the suction module 4 on the lifting plate 3, thereby adjusting the distance between the two suction modules 4, and thus meeting the requirements for the use of different sizes of backing plates 14.

[0024] In this embodiment, each suction cup 8 is connected to the mounting plate 7 via an adjustment block 10. This structural design facilitates the connection between the suction cup 8 and the mounting plate 7.

[0025] In this embodiment, the adjustment block 10 is slidably connected to the mounting plate 7 and is locked to the mounting plate 7 via a locking member; specifically, the locking member is a bolt. Loosening the locking member allows the adjustment block 10 to slide relative to the mounting plate 7, thereby adjusting the position of the adjustment block 10 and the suction cup 8 on the mounting plate 7, thereby adjusting the distance between two adjacent suction cups 8, and thus meeting the requirements for the use of backing plates 14 of different sizes.

[0026] In this embodiment, the lifting plate 3 and the mounting plate 7 are arranged vertically.

[0027] In this embodiment, the lifting drive mechanism 2 includes a fixed plate 11 mounted on the inner wall of the lifting chamber 6 and a cylinder 12 mounted on the fixed plate 11. The lifting plate 3 is mounted on the piston rod of the cylinder 12. In actual use, the piston rod of the cylinder 12 is extended and retracted to drive the lifting plate 3 to move up and down.

[0028] In this embodiment, the mounting plate 7 is equipped with a sensor 13 ; the sensor 13 is used to sense the pad 14 .

[0029] All technical features in this embodiment can be freely combined according to actual needs.

[0030] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
