Description

Technical Field

[0001] This utility model relates to the field of flipping equipment technology, specifically a material flipping mechanism. Background Technology

[0002] Printed circuit boards (PCBs) are key fundamental components of various electronic devices, and their quality plays a decisive role in the overall performance and reliability of these devices. Therefore, rigorous quality inspection is essential during the PCB manufacturing process. Currently, there are various inspection technologies for PCBs, commonly including manual visual inspection, automated optical inspection (AOI), and automated X-ray inspection (AXI).

[0003] Automated Optical Inspection (AOI) technology uses an optical imaging system to capture images of circuit boards, and then uses image processing algorithms to compare and analyze these images with preset standard images to determine whether the circuit boards have defects. AOI technology overcomes some of the shortcomings of manual visual inspection to a certain extent, possessing high detection accuracy and efficiency, and can detect a variety of external and some hidden defects.

[0004] In some circuit board inspection processes, it is necessary to inspect both sides of the circuit board separately. Therefore, a flipping mechanism is required to flip the circuit board. The existing flipping mechanism clamps the circuit board with a clamping component. When flipping, the circuit board flips 180 degrees along a semi-circular arc trajectory to the side of its original position. Although it completes the flipping of the circuit board, it requires a large flipping space and cannot be used in narrow processing spaces.

[0005] In view of this, there is an urgent need for a material flipping mechanism. Utility Model Content

[0006] To address the problems existing in the prior art, this utility model solves the problem using the following technical structure.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A material turning mechanism includes: a frame, on which a mounting plate, two carrier plates, a first driving mechanism and a second driving mechanism are provided. The mounting plate is located on one side of the frame, and the two carrier plates are located opposite each other on the side of the mounting plate away from the frame. Each of the two carrier plates has a plurality of vacuum adsorption holes on the side that is close to each other, and there is a clamping space between the two carrier plates.

[0009] The first driving mechanism is used to drive the mounting plate to rotate in the vertical direction;

[0010] The second drive mechanism is used to drive the two carrier plates to move towards each other or away from each other.

[0011] Its further feature is that,

[0012] The first driving mechanism includes a rotary table and a first motor. The rotary table is rotatably mounted on the frame, and the mounting plate is mounted on the rotary table. The first motor is used to drive the rotary table to rotate.

[0013] A slide rail is provided on one side of the mounting plate, and a connecting plate is provided on one side of the carrier plate. The connecting plate is slidably mounted on the slide rail.

[0014] The second drive mechanism includes a second motor and a gear. The second motor is mounted on a rotary table, and the gear is coaxially mounted on the output end of the second motor. A rack is provided on the connecting plate.

[0015] The rack extends in the same direction as the slide rail, and the two racks are respectively disposed on both sides of the gear and mesh with the gear.

[0016] Both ends of the slide rail are provided with slotted optocouplers, and the connecting plate is provided with photoelectric baffles adapted to the slotted optocouplers.

[0017] The carrier plate is provided with a buffer and a buffer seat on each side, and the buffer and buffer seat on the two carrier plates are provided on different sides.

[0018] The frame is provided with limit rubber blocks above and below the rotary table, and the mounting plate is provided with two limit posts. When the limit post abuts against either of the limit rubber blocks, the carrier plate is in a horizontal state.

[0019] The vacuum adsorption holes on the carrier plate are divided into three adsorption areas arranged in parallel. The carrier plate is provided with three independent vacuum adsorption pipelines, and the three independent vacuum adsorption pipelines correspond one-to-one with the three adsorption areas.

[0020] Each of the two carrier plates has three vacuum tube interfaces on the side that is far apart from each other, and the three vacuum tube interfaces are respectively connected to three vacuum adsorption pipelines.

[0021] Two vacuum generators are installed at the bottom of the frame, and the two vacuum generators are respectively connected to three vacuum tube interfaces on two carrier plates through two main pipelines.

[0022] The above-described structure of this utility model can achieve the following beneficial effects:

[0023] During processing, the second drive mechanism drives two carrier plates to move away from each other. The material is placed on the top surface of the bottom carrier plate, and a vacuum is drawn on the bottom carrier plate to adsorb and fix the material. Then, the second drive mechanism drives the two carrier plates to move towards each other until the carrier plate above or below is very close to the material. At this time, the first drive mechanism drives the mounting plate to rotate vertically, so that the two carrier plates rotate evenly, completing the flipping of the material. Then, the upper carrier plate releases the adsorption of the material, while the lower carrier plate is vacuumed to adsorb the material. The second drive mechanism drives the two carrier plates to move away from each other, and then the robot arm transfers the flipped material to the next process step. During the flipping process, this mechanism does not occupy the space on both sides, requires less flipping space, is convenient for use in narrow spaces, and improves the adaptability of the mechanism.

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0030] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0031] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0032] refer to Figures 1-3 The material turning mechanism shown includes: a frame 1, on which a mounting plate 2, two carrier plates 3, a first drive mechanism, and a second drive mechanism are mounted. The mounting plate 2 is located on one side of the frame 1, and the two carrier plates 3 are located opposite each other on the side of the mounting plate 2 away from the frame 1. Each of the two carrier plates 3 has several vacuum adsorption holes on the side closest to each other, and a clamping space exists between the two carrier plates 3. During processing, the second drive mechanism drives the two carrier plates 3 to move away from each other, placing the material on the top surface of the bottom carrier plate 3. A vacuum is then drawn onto the bottom carrier plate 3 to adsorb and fix the material. Then, the second drive mechanism drives the two carrier plates 3 to move towards each other until a clamping or positioning effect is formed. When the upper carrier plate 3 is very close to the material, the first drive mechanism drives the mounting plate 2 to rotate vertically, causing both carrier plates 3 to rotate 180 degrees (i.e., the positions of the two carrier plates 3 are interchanged). At this time, the material is flipped. Then, the upper carrier plate 3 releases its adsorption of the material, while the lower carrier plate 3 is vacuumed to adsorb the material. The second drive mechanism drives the two carrier plates 3 to move away from each other. Then, the robot transfers the flipped material to the next process step. During the material flipping process, this mechanism does not occupy the space on both sides, requires less flipping space, is convenient for use in narrow spaces, and improves the adaptability of the mechanism.

[0033] like Figure 1 and Figure 2 As shown, the first driving mechanism specifically includes a rotary table 4 and a first motor 5. The rotary table 4 is rotatably mounted on the frame 1, and the mounting plate 2 is mounted on the rotary table 4. The first motor 5 is used to drive the rotary table 4 to rotate. The rotary table 4 (with its axis facing horizontally) is mounted by setting a round hole on the frame 1. Then, the mounting plate 2 is placed on the rotary table 2, and the first motor 5 drives the rotary table 4 to rotate, thereby achieving the purpose of driving the mounting plate 2 to rotate, and thus realizing the interchange of the positions of the two carrier plates 3.

[0034] like Figure 3 and Figure 4As shown, in order to limit the movement of the two carrier plates 3, a slide rail 21 is provided on one side of the mounting plate 2, and a connecting plate 31 is provided on one side of the carrier plate 3. The connecting plate 31 is slidably mounted on the slide rail 21, so that the two carrier plates 3 can only move in the extension direction of the slide rail 21.

[0035] like Figure 3 and Figure 4 As shown, the second drive mechanism specifically includes a second motor 6 and a gear 7. The second motor 6 is mounted on the rotary table 4, and the gear 7 is coaxially mounted on the output end of the second motor 6. A rack 32 is mounted on the connecting plate 31. The extending direction of the rack 32 is consistent with the extending direction of the slide rail 21. The two racks 32 are respectively mounted on both sides of the gear 7 and are both meshed with the gear 7. Thus, by driving the gear 7 to rotate through the second motor 6, the two racks 32 located on both sides of the gear 7 move in opposite directions, thereby driving the two carrier plates 3 to move towards or away from each other.

[0036] like Figure 1 and Figure 3 As shown, in order to detect the extreme positions of the back-to-back movement of the two carrier plates 3, slotted optocouplers 23 are provided at both ends of the slide rail 21, and photoelectric baffles 33 adapted to the slotted optocouplers 23 are provided on the connecting plate 31. When the photoelectric baffles 33 are in the detection area of ​​the slotted optocouplers 23, it indicates that the carrier plate 3 has been placed in the extreme position.

[0037] like Figure 4 As shown, in order to buffer the movement of the two carrier plates 3 towards each other, a buffer 34 and a buffer seat 35 are respectively provided on both sides of the carrier plate 3. The buffer 34 and the buffer seat 35 on the two carrier plates 3 are located on different sides. When the carrier plates 3 approach each other, the buffer end of the buffer 34 abuts against the buffer seat 35 of the other carrier plate 3, thus providing buffer for the carrier plate 3.

[0038] like Figure 2 and Figure 3 As shown, in order to limit the rotation of the mounting plate 2 until it stops, the frame 1 is provided with limit rubber blocks 11 above and below the rotary table 4. The mounting plate 2 is provided with two limit posts 22. When the limit post 22 abuts against either of the limit rubber blocks 11, the carrier plate 3 is in a horizontal state, and the mounting plate 2 stops at a more accurate position, which is convenient for the subsequent handling of materials by the robot.

[0039] like Figures 2-4As shown, in order to adsorb materials of various specifications, the vacuum adsorption holes on the carrier plate 3 are divided into three adsorption areas arranged in parallel. The carrier plate 3 is equipped with three independent vacuum adsorption pipelines, which correspond one-to-one with the three adsorption areas. Each of the two carrier plates 3 has three vacuum tube interfaces 8 on the side away from each other. The three vacuum tube interfaces 8 are connected to the three vacuum adsorption pipelines respectively. By dividing the clamping surface of the carrier plate 3 into three adsorption areas arranged in parallel, the corresponding number of adsorption areas can be selected for adsorption according to the size of the material. If the material is large, the three adsorption drives will simultaneously perform vacuum hole adsorption. If the material is small, one adsorption drive will be used for adsorption, which is suitable for adsorption and flipping of materials of different sizes. In addition, two vacuum generators 9 are set at the bottom of the frame 1. The two vacuum generators 9 are connected to the three vacuum tube interfaces 8 on the two carrier plates 3 through two main pipelines. That is to say, the adsorption on the two carrier plates 3 is independently controlled by the two vacuum generators 9. Air valves are also set at the three vacuum tube interfaces 8 to open and close the corresponding adsorption areas.

[0040] The working principle of this utility model is as follows: During processing, the second drive mechanism drives two carrier plates 3 to move away from each other, placing the material on the top surface of the bottom carrier plate 3. The bottom carrier plate 3 is then vacuumed to adsorb and fix the material. Then, the second drive mechanism drives the two carrier plates 3 to move towards each other until the upper carrier plate 3 is very close to the material. At this time, the first drive mechanism drives the mounting plate 2 to rotate vertically, causing both carrier plates 3 to rotate 180 degrees, thus completing the flipping of the material. Then, the upper carrier plate 3 releases the adsorption of the material, while the lower carrier plate 3 is vacuumed to adsorb the material. The second drive mechanism drives the two carrier plates 3 to move away from each other, and then the robot arm transfers the flipped material to the next process step. During the flipping process, this mechanism does not occupy the space on both sides, requires less flipping space, and is suitable for use in confined spaces, thus improving the adaptability of the mechanism.

[0041] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
