Description

Technical Field

[0002] PCB is a thin board, which needs special carriers to protect and position it during processing. For PCBs that need to be processed or inspected on both sides, a flip mechanism needs to be set during processing so that both the front and back sides of the PCB are facing the inspection device or processing device.

[0003] In the prior art, a special flipping mechanism, such as a manipulator, is provided to first clamp the PCB board from the carrier, then flip it 180° through the flipping mechanism, and then place the PCB board on the conveyor belt or workstation of the next process through the flipping mechanism. This method of directly clamping the PCB board is easy to damage the PCB board, and there is also the problem of inaccurate position when placing it at the corresponding position of the next process. Of course, there are also flipping mechanisms with special carriers for completely positioning the PCB board so that it can be turned upside down, and then the PCB board is taken out of the carrier through the split module and then moved to the next workstation. The carrier of this type of flipping mechanism is relatively complex, and it is troublesome to put in or take out the PCB board, which is not conducive to improving production efficiency.

[0048] Figure 1 FIG. 1 is a schematic structural diagram of a PCB board turning and transporting device 100 according to an embodiment of the present invention. Figure 2 for Figure 1A schematic structural diagram of the first cover carrier 10 of the PCB board turning and transporting device 100 in the embodiment. Figure 3 for Figure 1 A schematic diagram of the assembly structure of the first cover carrier 10 of the PCB board turning and transporting device 100 in the embodiment and the second cover carrier 31 when the first cover carrier 10 is located at a preset position. Figure 4 for Figure 1 The structural diagram of the turning mechanism 30 of the PCB board turning and transporting device 100 in the embodiment. Figure 1 As shown, in one embodiment, the PCB board turning and transporting device 100 includes a first cover carrier 10, a conveying mechanism 20 and a turning mechanism 30. Figure 2 As shown, the first cover carrier 10 is disposed on the horizontal conveyor belt and moves along with the horizontal conveyor belt. The top surface of the first cover carrier 10 is used to carry at least one PCB board. The first cover carrier 10 is provided with a through hole 101 corresponding to the PCB board. The through hole 101 is used to expose the processing area of ​​the PCB board. In this embodiment, Figure 2 As shown, the first cover carrier 10 includes three through holes 101 for carrying three PCB boards. The top surface of the first cover carrier 10 is provided with a positioning protrusion group 11 at the edge of each through hole 101, and each positioning protrusion group 11 is used to limit the degree of freedom of a PCB board in the length direction and the width direction. The transfer component is used to transfer the first cover carrier 10 with the PCB board to a preset position. Figure 4 As shown, the flipping mechanism 30 includes a second cover carrier 31, a clamping assembly and a flipping assembly 33. The second cover carrier 31 has the same structure as the first cover carrier 10, and the second cover carrier 31 is arranged with the side of the positioning protrusion group 11 facing downward, that is, the first cover carrier 10 and the second cover carrier 31 are actually exactly the same workpiece, but are used in different working positions and are placed in opposite directions. Figure 3As shown, when the first cover plate carrier 10 moves to the preset position, it is aligned with the second cover plate carrier 31 in the vertical direction and the positioning protrusion group 11 of the two vertically connects the first cover plate carrier 10 and the second cover plate carrier 31. It can be understood that the positioning protrusion of the first cover plate carrier 10 directly contacts the bottom surface of the second cover plate carrier 31, and the positioning protrusion of the second cover plate carrier 31 directly contacts the top surface of the first cover plate carrier 10, so that when the PCB is subsequently flipped, the positioning protrusion can prevent the PCB board from shifting in the width and length directions. The clamping assembly is used to clamp the first cover plate carrier 10 and the second cover plate carrier 31 when the first cover plate carrier 10 is located at the preset position. For example, the clamping assembly can be a commonly used clamping claw mechanism. The flipping assembly 33 is used to flip the first cover plate carrier 10 and the second cover plate carrier 31 clamped by the clamping assembly by 180 degrees. After the processing or detection is completed, the second cover plate carrier 31 and the PCB board are moved out, and the first cover plate carrier 10 is retained at the flipping mechanism 30. That is to say, the purpose of flipping here can be to detect the two sides of the PCB board, or to process the two sides of the PCB board. There is no limitation here. After the detection or processing is completed, the second cover carrier 31 and the PCB board can be removed by other mechanisms or the above-mentioned conveying mechanism 20.

[0049] The PCB board flipping and transportation device 100 of this embodiment is provided with a first cover plate carrier 10 and a second cover plate carrier 31 with the same structure. The PCB board is first positioned by the positioning protrusion group 11 on the first cover plate carrier 10, and the first cover plate carrier 10 with the PCB board is transferred to the bottom of the second cover plate carrier 31 of the flipping mechanism 30 by the conveying mechanism 20. The first cover plate carrier 10 and the second cover plate carrier 31 are clamped by the clamping assembly. At this time, the front side of the PCB board can be processed or inspected, and then the first cover plate assembly, the PCB board and the second cover plate carrier 31 are flipped together by the flipping assembly 33, and then the back side of the PCB board is processed or inspected. At this time, the PCB board falls and is positioned on the second cover plate carrier 31. After the processing or inspection is completed, the second cover plate carrier 31 with the PCB board positioned is moved out, and the first cover plate carrier 10 is retained at the flipping mechanism 30 as the second cover plate carrier 31 for the next PCB board. The first cover carrier 10 and the second cover carrier 31 made of the same structure can realize the universality of the carrier, and there is no need to set up a separate split transfer mechanism to transfer the PCB board from the flip mechanism 30 to the carrier of the next process, which simplifies the structure and transfer action. In addition, during the flipping process, the PCB board can be protected by the first cover carrier 10 and the second cover carrier 31 and is not easily damaged.

[0050] Furthermore, when at the preset position, the positioning protrusion group 11 of the first cover carrier 10 and the second cover carrier 31 vertically connects the first cover carrier 10 and the second cover carrier 31, so that when the flipping mechanism 30 is flipped, the PCB board moves vertically and the freedom in other directions is restricted. Therefore, the position accuracy during flipping can be guaranteed, and it can accurately fall into the second cover carrier 31 after flipping.

[0051] In one embodiment, if Figure 2 As shown, the positioning protrusion group 11 includes a plurality of positioning posts 111, for example Figure 2 Two positioning posts 111 are provided at the four top corners of the through opening 101. The positions of the positioning posts 111 need to ensure that the first cover carrier 10 and the second cover carrier 31 do not interfere with each other when they are close to each other. The first cover carrier 10 also includes at least one positioning hole group, and the positioning hole group includes at least one positioning hole 102, such as Figure 2 In the embodiment, two positioning holes 102 are provided at two diagonal positions of the through opening 101. Figure 3 As shown, at the preset position, the positioning column 111 of the first cover carrier 10 is partially inserted into the corresponding positioning hole 102 of the second cover carrier 31, and the positioning column 111 of the second cover carrier 31 is partially inserted into the corresponding positioning hole 102 of the first cover carrier 10. Figure 3 As shown, at the preset position, the through opening 101 of the first cover carrier 10 is used to expose part of the positioning posts 111 of the second cover carrier 31 , that is, the shape of the through opening 101 not only ensures that the processing area of ​​the PCB board is exposed, but also reserves a partial area to avoid the positioning posts 111 .

[0052] In this embodiment, by providing the positioning holes 102 , it is possible to ensure that the first cover carrier 10 is aligned with the second cover carrier 31 when they are docked at a preset position.

[0053] Furthermore, by providing an area for avoiding the positioning posts 111 through the through opening 101 , it is advantageous to arrange more positioning posts 111 , thereby better positioning the PCB board.

[0054] In one embodiment, if Figure 1 As shown, the above-mentioned conveying mechanism 20 includes a horizontal transmission mechanism 21 and a lifting mechanism 22. The horizontal transmission mechanism 21 is used to drive the first cover carrier 10 to move in the horizontal direction. When it moves to the bottom of the flipping mechanism 30, the lifting mechanism 22 lifts the first cover carrier 10 to a preset position.

[0055] Furthermore, if Figure 4As shown, the flip mechanism 30 further includes a base plate 34 and a partition plate 35. The base plate 34 is provided with a mounting opening 341 which passes through from top to bottom. The partition plate 35 is provided on two opposite sides of the mounting opening 341, for example, on two sides in the width direction of the mounting opening 341, that is, on the long side of the mounting opening 341. The top surface of the partition plate 35 is used to overlap the second cover plate carrier 31, and the bottom of the partition plate 35 is provided with the first cover plate carrier 10.

[0056] In this embodiment, by providing the partition plate 35 , the second cover carrier 31 located above the partition plate 35 can be stably positioned on the substrate 34 even when the clamping assembly is removed.

[0057] Figure 5 FIG. 1 is a top view of a turning mechanism 30 of a PCB turning and transporting device 100 according to an embodiment of the present invention. Figure 6 for Figure 5 In one embodiment, as shown in FIG. Figure 3 As shown, the clamping assembly includes a first clamping assembly 321 and a second clamping assembly 322. The first clamping assembly 321 may include a first clamping member symmetrically arranged on both sides of the long side or short side of the mounting opening 341 of the substrate 34, and is used to clamp the first cover plate carrier 10 and the second cover plate carrier 31 on both sides in the width direction or the length direction. The second clamping assembly 322 is used to clamp the first cover plate carrier 10 and the second cover plate carrier 31 on both sides in the thickness direction. In this embodiment, the second clamping assembly 322 includes two clamping jaws 301 arranged up and down, and the first clamping member includes a telescopic cylinder, which is used to clamp the first cover plate carrier 10 and the second cover plate carrier 31 on both sides in the width direction when extended. As shown Figure 6 As shown, when the first cover carrier 10 moves to the preset position, the two clamping jaws 301 extend below the first cover carrier 10 and above the second cover carrier 31 , and then the two clamping jaws 301 are controlled to approach each other to clamp the first cover carrier 10 and the second cover carrier 31 .

[0058] Furthermore, if Figure 4 As shown, a plurality of first through holes 342 are provided at each long side wall of the mounting opening 341. The flip mechanism 30 further includes a plurality of support assemblies 36 corresponding to the first through holes 342 one by one, and the support assemblies 36 include support jaws 361 that can be controllably extended or retracted from the first through holes 342, and the support jaws 361 are used to clamp the first cover plate carrier 10 and the second cover plate carrier 31. In one embodiment, the support jaws 361 are connected to a rotation drive mechanism, and the rotation drive mechanism is used to control the support jaws 361 to rotate and form a state of extending or retracting from the first through holes 342. Figure 6 As shown, in one embodiment, the support clamp 361 is provided with a positioning groove 362 including upper and lower positioning surfaces.

[0059] Furthermore, if Figure 4 As shown, a second through hole 343 is provided at the side wall of the installation opening 341. The flip mechanism 30 further includes a knocking assembly 37, which includes a knocking member 371 that can be controllably extended or retracted from the second through hole 343. The knocking member 371 is used to knock the side of the PCB board so that the flipped PCB board falls off from the first cover carrier 10. The number of the knocking assemblies 37 can be multiple and symmetrically arranged on opposite sides of the installation opening 341, for example Figure 4 In the illustrated embodiment, the flip mechanism 30 includes two knocking components 37 symmetrically arranged on both sides of the width direction of the installation opening 341. The knocking components 37 here can be cylinders, which can knock the first cover carrier 10 and the second cover carrier 31 at a certain frequency by controlling the cylinders on both sides to extend at the same time. Flexible protective materials can be provided at the ends of the knocking members 371 to avoid damage to the carriers.

[0060] The above-mentioned clamping assembly, supporting assembly 36, and knocking assembly 37 are all arranged on the substrate 34. When the flipping assembly 33 drives the substrate 34 to flip, the clamping assembly, supporting assembly 36, knocking assembly 37, the first cover carrier 10, the second cover carrier 31 and the PCB board are flipped together.

[0061] When the device is working, first, the horizontal transmission mechanism 21 drives the first cover carrier 10 with the PCB board positioned thereon to move in the horizontal direction ( Figure 1The first cover plate carrier 10 is moved to the bottom of the flip mechanism 30 (direction a in the figure), and then the first cover plate carrier 10 is lifted to the preset position below the second cover plate carrier 31 of the flip mechanism 30 by the lifting mechanism 22. At this time, the first cover plate carrier 10 and the second cover plate carrier 31 are aligned and assembled into a positioning module. Then, the first clamping assembly 321 and the second clamping assembly 322 are started, and the first clamping assembly 321 extends to clamp the two sides of the width direction of the positioning module. The two clamping claws 301 of the second clamping assembly 322 first extend to the upper and lower sides of the positioning module, and then approach each other to clamp the positioning module in the thickness direction. At the same time, the support assembly 36 is started, and the rotation drive mechanism controls the support claw 361 to rotate and extend from the first through hole 342 and clamp the positioning module, so that the support claw 361 is supported at multiple points at the long side of the positioning module. After the clamping assembly is clamped and the support claw 361 is extended, the front of the PCB board is inspected or processed by the detection mechanism or processing assembly at the flip mechanism 30. After the inspection or processing is completed, the flip assembly 33 is started to make the back side of the PCB board face up, and then the back side of the PCB board is inspected or processed. The knocking assembly 37 can knock before or after the back side of the PCB board is processed or tested, so that the PCB board falls to the second cover carrier 31. After the inspection or processing of the back side of the PCB board is completed, the lifting mechanism 22 supports the bottom surface of the second cover carrier 31, and then retracts the support assembly 36, the knocking assembly 37 and the clamping assembly. The lifting mechanism 22 moves down with the second cover carrier 31 to the horizontal transmission mechanism 21, and is moved out by the horizontal transmission mechanism 21. The first cover carrier 10 is supported by the partition plate 35 at the base plate 34 and remains at the flip mechanism 30 as the second cover carrier 31 for the next flip.

[0062] In this embodiment, a plurality of support components 36 are provided on each long side wall of the installation opening 341, and the first cover plate carrier 10 and the second cover plate carrier 31 are supported by the support claws 361 of the support components 36. This can effectively support the thinner first cover plate carrier 10 and the second cover plate carrier 31 during the flipping process to prevent deformation, thereby preventing the PCB board from being deformed.

[0063] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
