Description

Technical Field

[0001] This utility model relates to the field of circuit board board retrieval machine technology, and in particular to a board retrieval machine for processing printed circuit boards. Background Technology

[0002] Circuit board handling machines are specialized equipment used in the electronics manufacturing industry for the transfer of printed circuit boards (PCBs). They are widely used to connect processes such as PCB production, surface mount technology (SMT), and testing. Their core function is to use mechanical structures, such as horizontal supports, drive mechanisms, and gripping mechanisms, to perform the gripping, handling, sorting, and loading / unloading operations of PCBs, thus replacing manual labor and automating the production line.

[0003] In scenarios where a board-retrieving machine picks up acid-washed circuit boards and transfers them to the cleaning process, existing gripping components, while equipped with suction cups featuring flexible buffer structures to accommodate the liquid-laden and slippery surfaces of acid-washed circuit boards, still have significant limitations in practical applications. Firstly, residual acidic substances on the circuit board surface easily corrode the suction cup material. Even with acid-resistant materials, frequent suction cup replacements are necessary, increasing maintenance costs and potentially impacting production line efficiency due to downtime. Secondly, acid, moisture, or oxide layers adhering to the circuit board surface after acid washing can damage the seal between the suction cup and the board, leading to decreased adsorption force. Furthermore, current suction cup configurations struggle to accommodate circuit boards of different sizes. Multiple suction cups are required for larger, heavier boards, while larger suction cups used for smaller, lighter boards can cause unbalanced adsorption forces, resulting in unstable gripping or even board detachment.

[0004] Therefore, it is necessary to provide a new type of board-retrieving machine for printed circuit board processing to solve the above-mentioned technical problems. Utility Model Content

The end of the slider away from the sliding groove one has a sliding groove two, and the sliding rod is slidably connected in the sliding groove two. A cross-shaped sliding groove is formed at the lower end of the disc, and multiple claws are slidably connected in the cross-shaped sliding groove.

[0018] In the specific implementation process, such as Figures 1-6 As shown, a board-retrieving machine for printed circuit board processing includes a fixed plate 1 and four support columns 2 located on the bottom wall of the fixed plate 1. Two longitudinal supports 6 are fixedly connected to the upper sides of the fixed plate 1, and transverse supports 7 are fixedly connected to the upper ends of the two longitudinal supports 6. A mounting plate 8 is fixedly connected to one end of each transverse support 7. An acid pickling tank 3 and a cleaning tank 4 are fixedly connected to the upper edge of the fixed plate 1. A gripping mechanism and a sliding assembly for driving the gripping mechanism to move alternately between the acid pickling tank 3 and the cleaning tank 4 are also provided between the two longitudinal supports 6. The sliding assembly includes a connecting plate 5 and a slide bar 51. The slider 52 and the drive mechanism are as follows: both ends of the connecting plate 5 are fixedly connected to the opposite ends of the two longitudinal supports 6; one end of the connecting plate 5 is fixedly connected to one end of the slide bar 51; one end of the slider 52 is provided with a slide groove 53 that cooperates with the slide bar 51; the slide bar 51 is slidably connected in the slide groove 53; four pillars 2 are used to support the fixed plate 1; when the motor 9 starts, the slide rod 12 moves horizontally while moving up and down; the slide bar 51 drives the slide rod 12 to move horizontally; the slide rod 12 slides longitudinally in the slide groove 54 on the slider 52; and the circuit board is transferred from the pickling tank 3 to the cleaning tank 4.

[0019] It should be noted that the reference Figures 1-3 As shown, the driving mechanism includes a motor 9, a rotating column 71, and a guide plate 10. The motor 9 is fixedly connected to one end of the mounting plate 8, and the output end of the motor 9 is fixedly connected to one end of the rotating column 71. The other end of the rotating column 71 is fixedly connected to one end of the guide plate 10. The middle end of the rotating column 71 is rotatably connected to the center of the transverse support 7, and one end of the connecting column 11 is rotatably connected to the other end of the guide plate 10. When the motor 9 is started, the motor 9 drives the rotating column 71 to rotate, and the rotating column 71 drives the guide plate 10 to move in an upward semi-circular motion along the transverse axis. The guide plate 10 drives the slide rod 12 to move.

[0020] It should be noted that the reference Figures 4-6As shown, the gripping mechanism includes a disc 1201, four claws 1202, a limiting block 1204, four electric push rods 1205, four sliding pins 1206, four springs 1207, and four sliding pins 1208. The end of the connecting post 11 away from the guide plate 10 is rotatably connected to one end of the sliding rod 12. The end of the sliding rod 12 away from the connecting post 11 is fixedly connected to the upper end of the disc 1201. The end of the slider 52 away from the sliding groove 53 has a sliding groove 54. The sliding rod 12 is slidably connected to the sliding groove 54. Inside slot 2 54, a cross-shaped sliding groove 1203 is formed at the lower end of the disc 1201. Four claws 1202 are slidably connected in the cross-shaped sliding groove 1203. One end of the slider 52 is fixedly connected to the center of the inner wall of the cross-shaped sliding groove 1203. One end of the four electric push rods 1205 is fixedly connected to one end of the limiting block 1204. The ends of the four electric push rods 1205 away from the limiting block 1204 are fixedly connected to one end of the four claws 1202. One end of the four sliding pillars 1206 is fixedly connected to the cross-shaped sliding groove 1203. On one side wall of 03, one end of each of the four sliding pillars 1208 is slidably connected to the end of each of the four sliding pillars 1206 away from the side wall of the cross groove 1203. The end of each of the four sliding pillars 1208 away from the four sliding pillars 1206 is fixedly connected to one end of each of the four claws 1202. The other end of the connecting pillar 11 is rotatably connected to one end of the sliding rod 12. When it is necessary to grip the circuit board, because the four claws 1202 have an inclined angle, the motor 9 drives the four claws 1202 to generate downward pressing force, causing the four sliding pillars 1202 to move downward. Column 2 1208 extends and retracts into the four sliding columns 1206. The circuit board causes the four claws 1202 to move in the opposite direction. When the circuit board reaches the slots on the four claws 1202, the circuit board is transferred into the cleaning box 4. When the four claws 1202 are lifted, the force of the four springs 1207 causes the four claws 1202 to tighten inward, so that the circuit board will not fall off. The four electric push rods 1205 pull back so that the four claws 1202 can place the circuit board into the cleaning box 4 for cleaning.

[0021] It should be noted that the reference Figures 4-6 As shown, one end of each of the four claws 1202 is provided with multiple slots. The four claws 1202 are of equal size, and their positions on the disc 1201 are matched. The distances between the four claws 1202 and the limiting block 1204 are equal. The multiple slots are provided to secure the circuit board and prevent it from falling off.

[0022] The working principle of this utility model is as follows: When the motor 9 starts, the slide rod 12 moves horizontally while reciprocating up and down. The slide bar 51 drives the slide rod 12 to move horizontally, and the slide rod 12 slides longitudinally in the second slide groove 54 on the slider 52, transferring the circuit board from the pickling tank 3 to the cleaning tank 4. The motor 9 starts, and the motor 9 drives the rotating column 71 to rotate. The rotating column 71 drives the guide plate 10 to move upward in a semi-circular motion along the horizontal axis. The guide plate 10 drives the slide rod 12 to move. When it is necessary to grab the circuit board, since the four claws 1202 have an inclined angle, the motor 9 drives the four claws 1202 to generate downward pressing force, causing the four second slide bars 1208 to extend and retract into the four first slide bars 1206. The circuit board is then gripped by the four claws 1202. 202 moves in the opposite direction. When the circuit board reaches the slots on the four claws 1202, it is transferred into the cleaning box 4. When the four claws 1202 are lifted, the force of the four springs 1207 causes the four claws 1202 to tighten inward, so that the circuit board will not fall off. The four electric push rods 1205 pull back so that the four claws 1202 can place the circuit board into the cleaning box 4 for cleaning. One end of the four claws 1202 has multiple slots. The four claws 1202 are of equal size. The positions of the four claws 1202 on the disc 1201 are matched, and the distance between the four claws 1202 and the limit block 1204 is equal. Multiple slots are provided to secure the circuit board and prevent it from falling off.
