[0005] However, the patent still has the following problems: After the circuit board enters the inside of the turning seat, the circuit board is fixed and turned over by the rigid clamping of the air cylinder and the clamping plate. Since the overall circuit board is relatively thin, this rigid clamping is very easy to damage the circuit board. Therefore, it is necessary to improve the existing equipment to overcome the above defects. Content of the Utility Model

[0006] The purpose of the utility model is to provide a novel circuit board turning device, which has the advantages of being able to flexibly clamp the circuit board, and being able to turn over and convey the circuit board.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A novel circuit board turning device includes a bottom plate, and a turning mechanism and a conveying mechanism are arranged on the surface of the bottom plate;

[0008] The flipping mechanism includes side plates and an air pump. A left - and - right - hand threaded screw rod is rotatably connected to the surface of the side plates. Two movable plates are threadedly connected to the surface of the left - and - right - hand threaded screw rod. An extension plate is arranged above the movable plates. Two combined plates are fixed to the surface of the extension plate. An installation plate and a support block are fixed to the surface of the combined plates. A flipping motor is fixed to the surface of the installation plate. A turntable is fixed to the output shaft of the flipping motor. A connecting rod is fixed to the surface of the turntable. An arc - shaped groove is formed on the surface of the support block. A U - shaped plate is fixed to the surface of the connecting rod. Clamping pads are communicated with both the upper and lower sides of the inner wall of the U - shaped plate. An air delivery pipe is communicated with the surface of the air pump. One end of the air delivery pipe penetrates through the combined plate and the support block and is communicated with a rotary joint.

[0009] Preferably, as a novel circuit board flipping device of the present utility model, the conveying mechanism includes a linear module. A height - increasing block is fixed to the bottom of the linear module. The bottom of the height - increasing block is fixedly connected to the surface of the bottom plate. A placement plate is fixed to the top of the moving part of the linear module. A circuit board placement board is fixed to the top of the placement plate.

[0010] Preferably, as a novel circuit board flipping device of the present utility model, an electric push rod is fixed to the surface of the movable plate. The top end of the electric push rod is fixedly connected to the surface of the extension plate.

[0011] Preferably, as a novel circuit board flipping device of the present utility model, a guide plate is fixed to the bottom of the extension plate. A sliding groove is formed inside the movable plate. The guide plate is slidably connected to the inner wall of the sliding groove.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] With the setting of the flipping mechanism in the present utility model, the circuit board can be flexibly clamped and flipped. Rotating the left - and - right - hand screw rod can cause the two movable plates to move towards or away from each other under the influence of the thread, so as to adapt to circuit boards of different sizes. After the conveying mechanism conveys the circuit board between the two U - shaped plates, the bottom plate position of the circuit board will be higher than the surface of the lower clamping pad. At this time, starting the air pump can make air pass through the air delivery pipe, rotary joint and U - shaped plate and be injected into the clamping pad, causing the clamping pad to expand and deform, so that the clamping pad can evenly fit on the surface of the circuit board, enabling the circuit board to obtain a flexible clamping effect. This can effectively avoid local stress concentration that may be caused by rigid clamping, help maintain the overall stability of the circuit board, and prevent damage to the circuit board during the clamping process. Then, raise the extension plate and start the flipping motor, so that the flipping motor can drive the turntable and connecting rod to rotate. At this time, the connecting rod will move inside the arc - shaped groove, enabling the U - shaped plate to flip 180 degrees, thus realizing the flipping effect of the circuit board. After that, reset the extension plate and the clamping pad, so that the circuit board can be released from the clamping and continue to be conveyed by the conveying mechanism.

Detailed Embodiment

[0022] Please refer to Figures 1-5, a new type of circuit board flipping device, including a bottom plate 1, on the surface of the bottom plate 1, there is a flipping mechanism 2 and a conveying mechanism 3;

[0023] The flipping mechanism 2 enables the circuit board to be flexibly clamped and flipped, and the conveying mechanism 3 is used to convey the circuit board.

[0024] The flipping mechanism 2 includes side plates 201 and an air pump 214. The number of side plates 201 is two. On the surface of the side plates 201, there is a forward and reverse thread screw 202 rotatably connected. One end of the forward and reverse thread screw 202 penetrates through one side plate 201 and is fixed with a handwheel. On the surface of the forward and reverse thread screw 202, there are two movable plates 203 threadedly connected. Above the movable plates 203, there is an extension plate 204. On the surface of the extension plate 204, there are two combined plates 205 fixed. On the surface of the combined plates 205, there are a mounting plate 206 and a support block 208 fixed. On the surface of the mounting plate 206, there is a flipping motor 207 fixed. The output shaft of the flipping motor 207 is fixed with a turntable 209. The output shaft of the flipping motor 207 penetrates through the mounting plate 206. On the surface of the turntable 209, there is a connecting rod 210 fixed. On the surface of the support block 208, there is an arc-shaped groove 213 opened. The connecting rod 210 is slidably connected with the inner wall of the arc-shaped groove 213. On the surface of the connecting rod 210, there is a U-shaped plate 211 fixed. On the upper and lower sides of the inner wall of the U-shaped plate 211, there are clamping pads 212 communicated. The clamping pads 212 are made of rubber material. The surface of the air pump 214 is communicated with an air delivery pipe 215. One end of the air delivery pipe 215 penetrates through the combined plate 205 and the support block 208 and is communicated with a rotary joint 216. One end of the rotary joint 216 is communicated with the U-shaped plate 211;

[0025] Rotating the forward and reverse thread screw 202 can make the two movable plates 203 move towards each other or in opposite directions under the influence of the thread, so as to adapt to circuit boards of different sizes. When the conveying mechanism 3 conveys the circuit board between the two U-shaped plates 211, the position of the bottom plate of the circuit board will be higher than the surface of the lower clamping pad 212. At this time, starting the air pump 214 can make air pass through the air delivery pipe 215, the rotary joint 216 and the U-shaped plate 211 and be injected into the clamping pad 212, so that the clamping pad 212 can generate expansion deformation, so that the clamping pad 212 can evenly fit on the surface of the circuit board, enabling the circuit board to obtain a flexible clamping effect. This can effectively avoid local stress concentration that may be caused by hard clamping, help maintain the overall stability of the circuit board, and prevent damage to the circuit board during the clamping process. Then, raise the extension plate 204 and start the flipping motor 207, so that the flipping motor 207 can drive the turntable 209 and the connecting rod 210 to rotate. At this time, the connecting rod 210 will move inside the arc-shaped groove 213, enabling the U-shaped plate 211 to be flipped by 180 degrees, thus realizing the flipping effect of the circuit board. After that, reset the extension plate 204 and the clamping pad 212, so that the circuit board can be released from the clamping and can continue to be conveyed by the conveying mechanism 3.

[0026] Further, the conveying mechanism 3 includes a linear module 301. A heightening block 302 is fixed to the bottom of the linear module 301, and the bottom of the heightening block 302 is fixedly connected to the surface of the bottom plate 1. A placing plate 303 is fixed to the top of the moving member on the surface of the linear module 301, and a circuit board placing plate 304 is fixed to the top of the placing plate 303. The top of the circuit board placing plate 304 is 1 cm - 2 cm higher than the top of the lower clamping pad 212.

[0027] The moving member on the surface of the linear module 301 can drive the placing plate 303 and the circuit board placing plate 304 to move, so that the placing plate 303 can move to one side of the conveying line, and the circuit board is received by the circuit board placing plate 304 and then conveyed by the linear module 301 between the two U-shaped plates 211. After the circuit board is flipped, the linear module 301 can continue to drive the circuit board placing plate 304 for conveying.

[0028] Further, an electric push rod 218 is fixed to the surface of the movable plate 203, and the top end of the electric push rod 218 is fixedly connected to the surface of the extension plate 204.

[0029] After the clamping pad 212 expands to clamp the circuit board, the electric push rod 218 can drive the extension plate 204 to move upward, so that the circuit board can be lifted, avoiding the collision between the surface of the circuit board and the circuit board placing plate 304 during the rotation of the circuit board.

[0030] Further, a guide plate 219 is fixed to the bottom of the extension plate 204, and a sliding groove is formed inside the movable plate 203. The guide plate 219 is slidably connected to the inner wall of the sliding groove.

[0031] When the extension plate 204 is lifted by the electric push rod 218, the guide plate 219 will slide on the inner wall of the sliding groove, so that the movement of the extension plate 204 is more stable and the extension plate 204 will not tip over.

[0032] Further, a corrugated pipe 217 is installed on the surface of the air delivery pipe 215.

[0033] The corrugated pipe 217 can be stretched and deformed, so as to ensure that the gas can be normally conveyed through the corrugated pipe 217 and the air delivery pipe 215.

[0034] Further, a sliding table 220 is fixed to the top of the bottom plate 1, and a slide rail is fixed to the surface of the sliding table 220. The bottom of the movable plate 203 is slidably connected to the surface of the slide rail.

[0035] When the movable plate 203 moves, the bottom surface thereof will be able to slide on the surface of the slide rail, so that the movable plate 203 can obtain a guiding effect and avoid rotation when the movable plate 203 moves.

[0036] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
