Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing technology, and in particular to a board taking machine. Background Technology

[0002] In existing patents, the applicant filed a Chinese patent application with application number 202210602713.X, which discloses an automatic frame unloading method and an automatic frame unloading device. Although it discloses that the frame unloading robot includes a vertical base, a plate picking unit, a plate picking lifting mechanism, and two side limiting components on the left and right sides of the plate picking unit, and the plate picking unit is slidably mounted on the vertical base, when the plate picking lifting mechanism drives the plate picking unit to lift and lower vertically to pick up the plate, the two side limiting components on the left and right sides of the circuit board respectively limit the two sides of the circuit board. However, when the tops of two adjacent plates are close together, the plate picking unit cannot accurately pick up the plates.

[0003] Therefore, the defects are very obvious, and a solution is urgently needed. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a board picking machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A plate-retrieving machine includes a translation drive mechanism, a vertical plate mounted on the translation end of the translation drive mechanism, a lifting drive mechanism mounted on the vertical plate, a clamping plate mechanism mounted on the lifting end of the lifting drive mechanism, two guide mechanisms symmetrically arranged on both sides of the lifting drive mechanism, and a suction plate separation mechanism mounted on the bottom of the vertical plate and located below the two guide mechanisms. The clamping plate mechanism is located between the two guide mechanisms. The suction plate separation mechanism includes a suction plate driver mounted on the bottom of the vertical plate and a suction plate separation assembly mounted on the drive end of the suction plate driver. The suction plate driver is used to drive the suction plate separation assembly to translate.

[0006] Furthermore, the suction plate separation assembly includes a telescopic driver mounted on the drive end of the suction plate driver, a translation plate mounted on the telescopic end of the telescopic driver, and one or more suction cups mounted on the translation plate. The telescopic driver is used to drive the translation plate and the suction cups to translate.

[0007] Furthermore, there are two suction plate separation mechanisms, which are symmetrically arranged at the bottom of the upright plate.

[0008] Furthermore, the plate take-up machine also includes a spacing adjustment mechanism installed on the upright plate, and two guide mechanisms are respectively installed on the two adjustment ends of the spacing adjustment mechanism. The spacing adjustment mechanism is used to adjust the distance between the two guide mechanisms.

[0009] Furthermore, the clamping mechanism includes a lifting driver disposed at the lifting end of the lifting drive mechanism, a finger cylinder disposed at the lifting end of the lifting driver, and two clamping blocks disposed at the two output ends of the finger cylinder respectively. The finger cylinder is used to drive the two clamping blocks to move closer or further apart from each other.

[0010] Furthermore, the clamping mechanism also includes a pair of photoelectric sensors mounted on one side of the cylinder body of the finger cylinder, and the photoelectric sensors are electrically connected to the finger cylinder.

[0011] Furthermore, there are two clamping mechanisms, and the distance between the two clamping mechanisms is set.

[0012] Furthermore, the lifting end of the lifting drive mechanism is equipped with an elastic buffer structure, and the clamping mechanism is installed at the elastic buffer end of the elastic buffer structure.

[0013] The beneficial effects of this utility model are as follows: In practical applications, the frame loaded with plates is located below this pick-and-place machine. Each plate is vertically inserted between two adjacent spacer bars of the frame. When the plate is thin, the top of the plate extends beyond the two adjacent spacer bars, making it easy for the top of the plate to sway, thus causing the tops of two adjacent plates to touch. When this pick-and-place machine picks up the plates, the translation drive mechanism drives the upright plate and the suction plate separation mechanism to translate to a preset position. Then, the telescopic end of the suction plate driver extends to drive the suction plate separation mechanism. The assembly moves forward from the top of the board until the suction plate separation assembly picks up the top side of the board. Then, the telescopic end of the suction plate driver retracts, driving the suction plate separation assembly and the top of the board to move backward, separating the tops of adjacent boards. Next, the lifting drive mechanism drives the clamping plate mechanism to move downward until the clamping plate end of the clamping plate mechanism clamps the bottom end of the separated board. Then, the lifting drive mechanism drives the clamping plate mechanism and the board to move upward. Two guide mechanisms guide the upward movement of the board to improve the stability of the upward movement. Each time the clamping plate mechanism removes a board from the frame, the translation drive mechanism drives the upright plate forward to a preset position to facilitate the clamping plate mechanism removing the next board. This invention separates the tops of adjacent boards by the suction plate separation mechanism before removing boards from bottom to top, preventing the tops of two boards from touching and causing the clamping plate mechanism to fail to clamp the boards accurately, thus improving the accuracy and stability of board removal.

Detailed Implementation To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0018] like Figures 1 to 3 As shown, the present invention provides a plate-retrieving machine, which includes a translation drive mechanism 1, a vertical plate 2 installed at the translation end of the translation drive mechanism 1, a lifting drive mechanism 3 installed at the vertical plate 2, a clamping plate mechanism 4 installed at the lifting end of the lifting drive mechanism 3, two guide mechanisms 5 symmetrically arranged on both sides of the lifting drive mechanism 3, and a suction plate separation mechanism 6 installed at the bottom of the vertical plate 2 and located below the two guide mechanisms 5. The clamping plate mechanism 4 is located between the two guide mechanisms 5. The suction plate separation mechanism 6 includes a suction plate driver 7 installed at the bottom of the vertical plate 2 and a suction plate separation assembly 8 installed at the driving end of the suction plate driver 7. The suction plate driver 7 is used to drive the suction plate separation assembly 8 to translate.

[0019] In practical applications, the loading frame 18, filled with plates, is located below the pick-and-place machine. Each plate is vertically inserted between two adjacent spacer bars 19 of the loading frame 18. When the plate is thin, the top of the plate extends beyond the two adjacent spacer bars 19, making it easy for the top of the plate to sway, thus causing the tops of two adjacent plates to touch. When the pick-and-place machine picks up the plates, the translation drive mechanism 1 drives the upright plate 2, along with the suction plate separation mechanism 6, to translate to a preset position. Then, the telescopic end of the suction plate driver 7 extends to drive the suction plate separation assembly 8 to... The top of the near-board piece moves forward until the suction plate separation assembly 8 picks up one side of the top of the board piece. Then, the telescopic end of the suction plate driver 7 retracts to drive the suction plate separation assembly 8, along with the top of the board piece, to move backward, separating the tops of adjacent boards. Next, the lifting drive mechanism 3 drives the clamping plate mechanism 4 to move downward until the clamping plate end of the clamping plate mechanism 4 clamps the bottom of the separated board piece. Then, the lifting drive mechanism 3 drives the clamping plate mechanism 4, along with the board piece, to move upward. Two guide mechanisms 5 guide the upward movement of the board piece to improve the stability of the upward movement. Specifically, each time the clamping plate mechanism 4 removes one board piece from the carrier frame 18, the translation drive mechanism 1 drives the upright plate 2 to move forward to a preset position so that the clamping plate mechanism 4 can remove the next board piece. Before removing the board piece from bottom to top, this invention separates the tops of adjacent boards through the suction plate separation mechanism 6, preventing the tops of two boards from touching and causing the clamping plate mechanism 4 to be unable to accurately clamp the board piece, thus improving the accuracy and stability of board removal.

[0020] In this embodiment, the suction plate separation assembly 8 includes a telescopic driver 9 mounted on the drive end of the suction plate driver 7, a translation plate 10 mounted on the drive end of the telescopic driver 9, and one or more suction cups 11 mounted on the translation plate 10. The telescopic driver 9 is used to drive the translation plate 10 and the suction cups 11 to translate. Specifically, both the suction plate driver 7 and the telescopic driver 9 can be horizontally arranged cylinders.

[0021] In practical applications, after the suction plate separation assembly 8 separates the tops of two adjacent plates and the clamping mechanism 4 clamps the top of the separated plates, the suction cup 11 releases its grip on the plates. The telescopic driver 9 drives the translation plate 10 to move backward along with the suction cup 11, so that the suction cup 11 separates from the plates. At this time, the lifting drive mechanism 3 can drive the clamping mechanism 4 to move upward along with the plates to remove the plates from the frame 18.

[0022] In this embodiment, there are two suction plate separation mechanisms 6, which are symmetrically arranged at the bottom of the upright plate 2. By having the two suction plate separation mechanisms 6 simultaneously suction one side of the same plate, it is beneficial to stably separate the tops of two adjacent plates.

[0023] In this embodiment, the board picking machine further includes a spacing adjustment mechanism 12 mounted on the upright plate 2. Two guide mechanisms 5 are respectively mounted on the two adjustment ends of the spacing adjustment mechanism 12. The spacing adjustment mechanism 12 is used to adjust the distance between the two guide mechanisms 5. According to the board pieces of different widths, the spacing adjustment mechanism 12 adjusts the spacing between the two guide mechanisms 5 so that the two guide mechanisms 5 can guide the board pieces of different widths.

[0024] In this embodiment, the clamping mechanism 4 includes a lifting driver 13 disposed at the lifting end of the lifting drive mechanism 3, a finger cylinder 14 disposed at the lifting end of the lifting driver 13, and two clamping blocks 15 respectively disposed at the two output ends of the finger cylinder 14. The finger cylinder 14 is used to drive the two clamping blocks 15 to move closer or further apart from each other; specifically, the lifting driver 13 can be a cylinder. In practical applications, when the clamping mechanism 4 clamps the plate to the required height, and the external robot picks up the plate, the finger cylinder 14 drives the two clamping blocks 15 to move away from each other to open. The two clamping blocks 15 release the plate, and then the lifting driver 13 drives the finger cylinder 14 and the two clamping blocks 15 to rise, so that the two clamping blocks 15 are higher than the plate, and the external robot can then remove the plate. Of course, the lifting driver 13 can also adjust the height of the two clamping blocks 15 to meet the clamping of plates of different heights.

[0025] In this embodiment, the clamping mechanism 4 also includes a pair of through-beam photoelectric sensors 16 installed on one side of the cylinder body of the finger cylinder 14. The through-beam photoelectric sensors 16 are electrically connected to the finger cylinder 14. When the two clamping blocks 15 are in the open state, both clamping blocks 15 are located between the pair of through-beam photoelectric sensors 16.

[0026] When the board is removed, the top of the board is located between the two clamping blocks 15. When a pair of through-beam photoelectric sensors 16 detect that there is a board between the two clamping blocks 15, the through-beam photoelectric sensors 16 send a signal to the finger cylinder 14, causing the finger cylinder 14 to drive the two clamping blocks 15 to move closer to each other to close, and the closed two clamping blocks 15 clamp the board.

[0027] In this embodiment, there are two clamping mechanisms 4, and the two clamping mechanisms 4 are spaced apart. The two clamping mechanisms 4 clamp the top of the same plate, which improves the stability of the clamping mechanism 4 clamping the plate.

[0028] In this embodiment, the lifting end of the lifting drive mechanism 3 is equipped with an elastic buffer structure 17, and the clamping mechanism 4 is installed at the elastic buffer end of the elastic buffer structure 17. The elastic buffer structure 17 provides buffer protection for the clamping mechanism 4, preventing the clamping mechanism 4 from experiencing hard impact collisions with external structures.

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

[0030] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
