Description

Technical Field

[0001] The utility model relates to the field of conveying technology, specifically a conveying mechanism of circuit board processing equipment. Background Art

[0002] The feeding mechanism of circuit board processing equipment is a key component used in automated production lines, responsible for transferring circuit board substrates or semi-finished products from one process to the next. Circuit board processing is a complex process, including but not limited to drilling, copper plating, etching, patching, welding and other steps. The design and performance of the feeding mechanism directly affect the efficiency, precision and stability of the entire production line.

[0003] However, in actual use, the existing circuit board processing requires multiple processes, and each process requires the use of a circuit board equipment feeding device, so as to save manpower and increase work efficiency. After the overall scanning of the circuit board is completed, it is necessary to inspect it. After the inspection is completed, the circuit board needs to be collected for the next processing. After the inspection of the circuit board is completed, the circuit board is transported to the bracket by a roller, and then the bracket is flipped to stack multiple circuit boards together at an angle. However, when the existing bracket is used for flipping and stacking, the circuit board that has completed the inspection will directly hit the circuit board that is stacked at an angle. Therefore, flipping and tilting stacking may cause physical damage to the circuit board, especially for high-density, thin or special-structured circuit boards. Flipping may cause components to fall off or circuits to break. For this reason, we propose a circuit board processing equipment feeding mechanism. Utility Model Content

[0004] A technical problem to be solved by this application is: how to design a feeding mechanism for circuit board processing equipment that can reduce the damage caused by flipped circuit boards to stacked circuit boards.

[0006] A placement table, which is provided on the machine body and is used for stacking circuit boards at an angle;

[0007] A limiting plate, wherein a plurality of limiting plates are provided and arranged on the side of the placement table;

[0008] The linkage component is arranged on the machine body and is used to synchronously move multiple limit plates to the side of the placement table when using the flip rack to prevent the flipped circuit board from directly contacting the stacked circuit boards.

[0009] In some embodiments, the linkage assembly includes a crankshaft arranged at the center of the shaft, both sides of which are arranged on the end faces of the shaft, a rotating plate movably provided on the main body of the crankshaft, a sliding rod movably provided on the end face of the rotating plate away from the crankshaft, a support frame provided on the top of the body, a sliding groove provided on the side of the support frame, the sliding rod movably provided on the inner wall of the sliding groove, and an opening and closing assembly for moving the limit plate on the outer surface of the placement table provided on the end face of the sliding rod.

[0010] In some embodiments, the opening and closing assembly includes a pull plate movably arranged on the outer surface of the sliding rod, an L-shaped plate is movably arranged inside the pull plate away from the sliding rod, a through groove is opened on the side of the pull plate, and the outer surface of the L-shaped plate is movably arranged inside the through groove.

[0011] In some embodiments, a rotating rod is movably provided on the inner wall of the side of the placing table, the side of the L-shaped plate is provided on the outer surface of the rotating rod, and the outer surface of the rotating rod is provided with multiple rotating blocks, and the sides of the multiple rotating blocks are respectively provided on the end faces of the corresponding limit plates.

[0012] In some embodiments, a silicone pad is provided on the end surface of the limiting plate that contacts the circuit board.

[0013] In some embodiments, a rotating assembly is provided on the side of the placement table, and the rotating assembly is used to move the circuit board to the frame after the circuit board is placed flat. A limiting groove is provided at the bottom of the placement table, and the rotating assembly includes connecting rods arranged on both sides of the inner wall of the limiting groove, and the outer surface of the connecting rod is movably set on the top of the body.

[0014] In some embodiments, limiting rods are movably provided on both sides of the interior of the pull plate, one end of the limiting rod passes through the top of the L-shaped plate and the inner wall of the pull plate in sequence, and a pull plate is provided. A tension spring is provided on the outer surface of the limiting rod, and the two ends of the tension spring are respectively provided at the top of the pull plate and the bottom of the pull plate.

[0015] This utility model has at least the following beneficial effects:

[0016] 1. When the shaft rotates, the linkage assembly first moves the circuit board on the flip rack to the placement table. At the same time, the linkage assembly can drive multiple limit plates to abut against the placement table, so that the conveyed circuit board cannot directly contact the stacked circuit boards, thereby reducing the contact between the two and preventing damage to the circuit boards caused by collision.

[0017] 2. When the circuit boards that have been inspected need to be moved, the rotating assembly can lay the stacked circuit boards flat, and then move the circuit boards from the placement table to the cart for the next step, which makes it easier to move and increases work efficiency.

Obviously, the described embodiment is only a part of the embodiment of this utility, not all of the embodiments. Based on the embodiment of this utility, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this utility.

[0027] Example 1

[0028] See also Figure 1-4 , this utility provides a technical solution:

[0029] A feeding mechanism for circuit board processing equipment includes a body 1, a moving roller 3 disposed inside the body 1, a shaft 5 disposed on the inner wall of the body 1 and driven by a motor, and a turning frame 4 disposed on the shaft 5, and further includes:

[0030] The placement table 2 is provided on the machine body 1 and is used to stack the circuit boards at an angle, thereby collecting the circuit boards that have been inspected.

[0031] A plurality of limit plates 8 are provided, which are arranged on the side of the placement table 2. The end surface of the limit plate 8 can contact the flipped circuit board;

[0032] The linkage assembly 6 is arranged on the body 1 and is used to synchronously move the multiple limit plates 8 to the side of the placement table 2 when using the flip frame 4 to prevent the flipped circuit board from directly contacting the stacked circuit boards.

[0033] The linkage assembly 6 includes a crankshaft 61 arranged at the center of the shaft 5, and both sides are arranged on the end faces of the shaft 5. A rotating plate 62 is movably provided on the main body of the crankshaft 61, and a sliding rod 64 is movably provided on the end face of the rotating plate 62 away from the crankshaft 61. A support frame 63 is provided on the top of the body 1, and a slide groove 65 is provided on the side of the support frame 63. The slide rod 64 is movably provided on the inner wall of the slide groove 65, and the end face of the slide rod 64 is provided with an opening and closing assembly 9 for moving the limit plate 8 on the outer surface of the placement table 2. The rotating plate 62 is a rotating setting for the crankshaft 61, and the outer surfaces of the rotating plate 62 and the slide rod 64 are also rotated, in order to prevent shaking when the two move.

[0034] The opening and closing assembly 9 includes a pull plate 91 movably arranged on the outer surface of the slide rod 64, and an L-shaped plate 93 is movably arranged inside the pull plate 91 away from the slide rod 64. A through groove 92 is provided on the side of the pull plate 91, and the outer surface of the L-shaped plate 93 is movably arranged inside the through groove 92. The through groove 92 is provided to enable the L-shaped plate 93 to have space to rotate, thereby reducing the occurrence of jamming.

[0035] A rotating rod 94 is movably provided on the inner wall of the side of the placement table 2, and the side of the L-shaped plate 93 is provided on the outer surface of the rotating rod 94. The outer surface of the rotating rod 94 is provided with multiple rotating blocks 95. The sides of the multiple rotating blocks 95 are respectively provided on the end faces of the corresponding limit plates 8. The sides of the L-shaped plate 93 and the rotating blocks 95 and the outer surface of the rotating rod 94 are fixed, so that the multiple limit plates 8 can be driven to move.

[0036] The end surface of the limiting plate 8 that contacts the circuit board is provided with a silicone pad 7 , which can reduce the impact force of the overturned limiting plate and reduce the damage caused by direct contact with the limiting plate 8 .

[0037] When using this device, first place the inspected circuit board on the moving roller 3. The moving roller 3 is induced to move the circuit board to the flip frame 4. The motor drives the shaft 5 to rotate. The shaft 5 drives the flip frame 4 set on the outer surface to rotate, and the circuit board set on the top is moved to the placement table 2. During the movement, the shaft 5 rotates to drive the crankshaft 61 set on the end face to rotate, and the crankshaft 61 drives the rotating plate 62 to move. At the same time, the rotating plate 62 drives the slide bar 64 to move inside the slide groove 65. The slide groove 65 drives the pull plate 91 set on the outer surface to move. The pull plate 91 drives the internal L-shaped plate 93 to move. The L-shaped plate 93 drives the internal rotating rod 94 to rotate on the side of the placement table 2. For this reason, the rotating rod 94 drives the rotating block 95 set on the outer surface to rotate. The rotating block 95 drives the limit plate 8 set on the side to contact the flipped circuit board to prevent it from directly contacting the stacked circuit boards, and then the reverse shaft 5 drives the flip frame 4 to reset, and at the same time can drive the crankshaft 61, the rotating plate 62 and the slide rod 64 to move, and the slide rod 64 drives the pull plate 91 set on the outer surface to reset, and the pull plate 91 drives the L-shaped plate 93 set inside to reset, so that the rotating rod 94 can be driven to reset, and the rotating rod 94 drives the rotating block 95 set on the outer surface and the limit plate 8 to reset. At this time, the circuit board on the outer surface of the limit plate 8 will enter the circuit boards stacked inside the placement table 2.

The rotating assembly 10 includes connecting rods 102 arranged on both sides of the inner wall of the limiting groove 101. The outer surface of the connecting rod 102 is movably set on the top of the body 1. The bottom of the placement table 2 is still provided on one side of the limiting groove 101 to prevent the placement table 2 from rotating to the flip frame 4 when the limiting plate 8 is pulled to move.

[0041] Limiting rods 105 are movably provided on both sides of the pull plate 91. One end of the limiting rod 105 passes through the top of the L-shaped plate 93 and the inner wall of the pull plate 91, and a pull plate 103 is provided. A tension spring 104 is sleeved on the outer surface of the limiting rod 105, and the two ends of the tension spring 104 are respectively provided at the top of the pull plate 103 and the bottom of the pull plate 91.

[0042] When it is necessary to move the stacked circuit boards by laying the placement table 2 flat, pull the pull plate 103 to drive the limit rod 105 set on the end surface to move, and the limit rod 105 moves out from the inside of the L-shaped plate 93. For this purpose, the pull plate 91 and the L-shaped plate 93 can be detached, and the placement table 2 can be rotated around the connecting rod 102 to be laid flat.
