Description

Technical Field

[0001] The utility model relates to the technical field of circuit board production equipment, in particular to an online circuit board turning device. Background Art

[0002] PCB (Printed Circuit Board), Chinese name is printed circuit board, also known as printed circuit board, printed circuit board, is an important electronic component, a support for electronic components, and a provider of electrical connections for electronic components. Because it is made using electronic printing technology, it is called a "printed" circuit board. Circuit boards are essential components in the current electronics industry, and are used for electrical connections of electronic components. In the production and processing of circuit boards, multiple processes such as cutting, drilling, copper plating, image transfer, etching, testing, and silk screen printing are required. Automated optical inspection (AOI) uses high-speed and high-precision visual processing technology to automatically detect various defects on circuit boards. The range of circuit boards can range from fine-pitch high-density boards to low-density large-size boards, and can be detected online, and is widely used in the production and processing of circuit boards. At present, when inspecting circuit boards, AOI equipment can generally only inspect one side of the circuit board at a time. If the other side needs to be inspected, the board needs to be flipped. The traditional method is to manually flip the board online. Manual flipping is prone to scratches, high labor intensity, low efficiency and cannot cope with flipping large boards. Therefore, the inspected circuit boards need to be collected and sent to the flipping machine for flipping. After flipping, the circuit boards are sent to the AOI equipment for inspection on the other side. Flipping the board after collection requires leaving the production line, which has a long transfer time and low efficiency. Utility Model Content

DETAILED DESCRIPTION

[0030] In order to facilitate those skilled in the art to understand the present invention, the present invention will be further described in detail below in conjunction with specific embodiments and drawings.

[0031] Reference Figures 1 to 6 The utility model provides an online circuit board flipping device, comprising a frame 1, an upper conveying mechanism 3, a lower conveying mechanism 4, a flipping mechanism 5, and a translation conveying mechanism 6. Among them: the frame 1 is provided with a lifting mechanism 2; the upper conveying mechanism 3 is provided on the lifting mechanism 2; the lower conveying mechanism 4 is provided on the lifting mechanism 2, and the upper conveying mechanism 3 and the lower conveying mechanism 4 are provided in parallel vertically; the flipping mechanism 5 is provided on the lifting mechanism 2; and the translation conveying mechanism 6 is provided on the lifting mechanism 2. The flipping mechanism 5 can rotate between the upper conveying mechanism 3 and the translation conveying mechanism 6. After the circuit board enters the upper conveying mechanism 3, the flipping mechanism 5 rotates, so that the circuit board flips 180° and is transferred to the translation conveying mechanism 6.

[0032] The translation conveying mechanism 6 and the lower conveying mechanism 4 are located on the same plane. The conveying direction of the translation conveying mechanism 6 is different from that of the lower conveying mechanism 4 . The translation conveying mechanism 6 conveys the flipped circuit board into the lower conveying mechanism 4 .

[0033] The flipping mechanism 5 includes a flipping bracket 51 connected to the lifting mechanism 2, a first carrier frame 52 connected to the flipping bracket 51, a second carrier frame 53 connected to the flipping bracket 51, at least one clamping assembly 54 arranged on the first carrier frame 52, and a flipping driving assembly 55 arranged on the lifting mechanism 2 for driving the flipping bracket 51 to rotate. There is a space between the first carrier frame 52 and the second carrier frame 53, and the circuit board can enter the space. In the initial state, the second carrier frame 53 and the upper conveying mechanism 3 are on the same plane. After the circuit board enters the upper conveying mechanism 3, it enters between the first carrier frame 52 and the second carrier frame 53.

[0034] The flip bracket 51 includes a flip shaft 511 disposed on the lifting mechanism 2, a first fixing frame 512 and a second fixing frame 513 respectively connected to both ends of the flip shaft 511, and the flip driving assembly 55 is in driving connection with the flip shaft 511. In this embodiment, the first fixing frame 512 and the second fixing frame 513 are L-shaped, so after flipping 180°, the height of the circuit board in the vertical direction also changes, that is, it is transferred from the upper conveying mechanism 3 at a high position to the translation conveying mechanism 6 at a low position.

[0035] The first carrier frame 52 and the second carrier frame 53 each include a fixing rod 521 connected between the first fixing frame 512 and the second fixing frame 513, and a plurality of bearing rods 522 connected to the fixing rod 521, wherein the plurality of bearing rods 522 are arranged in parallel. Specifically, the fixing rod 521 and the bearing rod 522 generally form an antenna shape. The first carrier frame 52 and the second carrier frame 53 can limit and carry the circuit board from the upper and lower sides of the circuit board. The clamping assembly 54 includes a clamping cylinder and a clamping block connected to the output end of the clamping cylinder. After the circuit board enters the first carrier frame 52 and the second carrier frame 53, the clamping assembly 54 clamps the circuit board to prevent the circuit board from being offset or falling during the flipping process.

[0036] The flip driving assembly 55 includes a transmission shaft 551 connected to the lifting mechanism 2 and a flip motor 552 for driving the transmission shaft 551 . Both ends of the transmission shaft 551 are respectively connected to both ends of the flip shaft 511 .

[0037] The translation conveying mechanism 6 includes a translation bracket 61 connected to the lifting mechanism 2, a plurality of translation conveying assemblies 62 arranged on the translation bracket 61, and a translation driving assembly 63 for driving the translation conveying assemblies 62, and there is a gap between adjacent translation conveying assemblies 62; the translation conveying assembly 62 includes a translation fixing plate 621 arranged on the translation bracket 61, a translation conveying belt 622 arranged on one side of the translation fixing plate 621, and the translation conveying belt 622 is connected to the translation driving assembly 63. The translation driving assembly 63 adopts a motor, a translation shaft, and a synchronous pulley group. The motor is connected to the translation shaft through the synchronous pulley group, and the translation shaft is connected to the translation conveying belts 622 of all the translation conveying assemblies 62, that is, one motor is used to drive all the translation conveying belts 622. In addition, in this embodiment, a profile is connected below the translation fixing plate 621 to play a fixing role and can also be used to fix the motor.

[0038] The lower conveying mechanism 4 includes a lower frame 41, a plurality of lower conveying wheel groups 42 arranged on the lower frame 41, and a gap between adjacent lower conveying wheel groups 42 for accommodating the translation conveying assembly 62. Figure 4 It can be seen that the left side of the translation conveying mechanism 6 extends beyond the range of the lifting mechanism 2 (at least it needs to be able to accommodate the circuit board to be inspected), and the right end of the translation conveying mechanism 6 extends into the lower conveying mechanism 4, so that the circuit board can be delivered into the translation conveying mechanism 6.

[0039] The lifting mechanism 2 includes a lifting drive member 21 disposed on the frame 1, a lifting frame 22 connected to the output end of the lifting drive member 21, and the upper conveying mechanism 3, the lower conveying mechanism 4, and the translation conveying mechanism 6 are all disposed on the lifting frame 22. In this embodiment, the lifting drive member 21 adopts a cylinder, and two cylinders are provided, and a guide rod is provided on the frame 1, and the lifting frame 22 is connected to the guide rod.

[0040] The upper conveying mechanism 3 includes an upper frame 31 connected to the lifting mechanism 2, a first upper conveying assembly 32 and a second upper conveying assembly 33 arranged on the upper frame, the first upper conveying assembly 32 and the second upper conveying assembly 33 are respectively located on opposite sides of the upper frame, and there is a gap between the first upper conveying assembly 32 and the second upper conveying assembly 33, and the gap is used to avoid the fixing rod 521 of the second bearing frame 53. The first upper conveying assembly 32 and the second upper conveying assembly 33 each include a plurality of upper conveying wheel groups 321 evenly arranged, and there is a gap between two adjacent upper conveying wheel groups 321, and the bearing rod 522 can enter the gap. In this embodiment, the structures of the upper conveying wheel group 321, the translation conveying wheel group, and the lower conveying wheel group 42 are similar, and a plurality of conveying wheels are arranged on the conveying shaft.

[0041] The upper conveying mechanism 3 includes a blocking assembly 34, which includes a blocking cylinder 341 connected to the upper frame 31 and a blocking member 342 connected to the output end of the blocking cylinder 341. When the circuit board enters the upper conveying mechanism 3, the blocking cylinder 341 drives the blocking member 342 to rise, which can block the circuit board and stop it at a predetermined position.

[0042] The circuit board online flipping device also includes a docking conveying mechanism 7, which includes a docking bracket 71 and a plurality of docking conveying wheel groups 72 arranged on the docking bracket 71. The docking conveying mechanism 7 is connected to the transmission mechanism of the AOI device to facilitate receiving the circuit board from the AOI device or sending the circuit board into the AOI mechanism.

[0043] During the specific operation, the docking conveying mechanism 7 is docked with the AOI equipment. After the AOI equipment detects the A side of the first circuit board, the first circuit board enters the upper conveying mechanism 3 from the docking conveying mechanism 7. At the same time, the first circuit board enters between the first carrier 52 and the second carrier 53, and the pressing component 54 presses the first circuit board. The flipping drive component 55 drives the flipping bracket 51 to flip, so that the first circuit board is flipped to the translation conveying mechanism 6. The pressing component 54 is released, and the translation conveying mechanism 6 sends the first circuit board to the lower conveying mechanism 4. At this time, the flipping mechanism 5 is reset, and the second circuit board enters the upper conveying mechanism 3. Then the lifting drive 21 drives the lifting frame 22 to rise, so that the lower conveying mechanism 4 reaches the same height as the docking conveying mechanism 7. The lower conveying component sends the first circuit board to the docking conveying mechanism 7, and the docking conveying mechanism 7 finally sends the first circuit board to the AOI equipment for B side detection. After the first circuit board is sent away, the lifting mechanism 2 is reset, and the flipping mechanism 5 flips the second circuit board, and the above operations are repeated, and so on. The above is one of the ways of flipping operation of the utility model. If in actual production, after detection, the circuit board needs to be flipped back to the A side on top, the circuit board that has finished the B side detection can be sent to the upper conveying mechanism 3 again for flipping, and the circuit board is flipped back to the A side on top. At this time, after the translation conveying mechanism 6 sends the circuit board to the lower conveying mechanism 4, the flipping mechanism 5 is reset, and the translation conveying mechanism 6 transfers the circuit board from the lower conveying mechanism 4, and the manipulator takes away the circuit board that has completed the detection. The specific operation method can be flexibly selected according to the needs of actual production.

[0044] The utility model is provided with an upper conveying mechanism 3, a lower conveying mechanism 4, a translation conveying mechanism 6 and a flipping conveying mechanism. After the circuit board having completed one side inspection enters the upper conveying mechanism 3 from the AOI device, it is flipped 180 degrees by the flipping mechanism 5 and then sent to the lower conveying mechanism 4 by the translation conveying mechanism 6. With the cooperation of the lifting mechanism 2, the circuit board is sent back to the AOI device for inspection on the other side. There is no need to flip the board offline, and the online flipping operation is realized. There is no need for manual operation, which greatly improves the flipping efficiency, improves the production efficiency and reduces the production cost.
