[0006] Furthermore, the clamping device includes a cylinder group arranged on the flip plate and a height-adjustable clamping mechanism connected to the cylinder group; the flip plate is also provided with a slide rail group, the clamping mechanism is arranged on the slide rail group and slides along the slide rail group driven by the cylinder group; the rotating mechanism includes a rotating cylinder arranged on the frame, the rotating cylinder is connected to a rotating transmission shaft, and the rotating transmission shaft is connected to the flip plate through a rotating transmission member. Thus, the stable operation of the flip device is achieved.

[0007] Further, the cylinder group includes a first cylinder and a second cylinder respectively arranged on the upper surface and the lower surface of the flip plate; the slide rail group includes a first slide rail and a second slide rail respectively arranged on the upper surface and the lower surface of the flip plate; the clamping mechanism includes a first machined workpiece group and a second machined workpiece group respectively arranged on the upper side and the lower side of the flip plate; the cylinder rod of the first cylinder is connected to the first machined workpiece group; the cylinder rod of the second cylinder is connected to the second machined workpiece group; one end of the first machined workpiece group is arranged on the first slide rail and moves along the first slide rail under the drive of the first cylinder; one end of the second machined workpiece group is arranged on the second slide rail and moves along the second slide rail under the drive of the second cylinder; the height of the first machined workpiece group and the second machined workpiece group are adjustable. The two cylinders drive the corresponding machined workpiece groups to run stably, and the slide rail can ensure that the running route of the machined workpiece group is stable and does not cause position deviation.

[0008] Furthermore, a universal wheel is provided on one side of the first machined workpiece group and the second machined workpiece group, and the universal wheel is in sliding contact with the transmission line, and there is a gap between the first machined workpiece group and the second machined workpiece group and the transmission line. Thus, it is ensured that the clamping device can stably clamp the circuit board during the clamping process, and the wear between the entire clamping mechanism and the transmission line can be minimized, thereby reducing unnecessary wear and loss.

[0009] Further, the first machined workpiece group includes a first machined workpiece A and a first machined workpiece B which are arranged up and down and matched and connected by a first adjusting device, the first machined workpiece A is arranged on the first slide rail and moves along the first slide rail driven by the first cylinder; the first adjusting device includes a first nut group and a first bolt which is passed through the first machined workpiece A and the first machined workpiece B, the first nut group fixes the first bolt in the first machined workpiece group and adjusts the distance between the first machined workpiece B and the first machined workpiece A; the second machined workpiece group includes a second The machined workpiece A and the second machined workpiece B, the second machined workpiece A is arranged on the second slide rail and moves along the second slide rail driven by the second cylinder; the second adjustment device includes a second nut group and a second bolt passing through the second machined workpiece A and the second machined workpiece B, the second nut group fixes the second bolt in the second machined workpiece group and adjusts the distance of the second machined workpiece B relative to the second machined workpiece A; the first machined workpiece B and the second machined workpiece B cooperate to clamp the circuit board on the transmission line, and the first machined workpiece B and the second machined workpiece B are both provided with the universal wheel on one side. Thus, the height and front and rear inclination of the clamping mechanism are adjustable through the fixing method of bolts and nuts, and the clamping device in the gluing and coating adopts the method of cylinder cooperating with the slide rail, which effectively eliminates the problem of "inward eight" and "outward eight" position relationship between the first machined workpiece group and the second machined workpiece group after operation.

[0010] Further, the first nut group includes a first nut A for fixing the first bolt on the first machined workpiece A, a first nut B for fixing the first bolt on the first machined workpiece B, and a first nut C arranged opposite to the first nut B; the second nut group includes a second nut A for fixing the second bolt on the second machined workpiece A, a second nut B for fixing the second bolt on the second machined workpiece B, and a second nut C arranged opposite to the second nut B.

When flipping, the slide rail is used to limit the movement of the upper and lower positions between the first slide rail or the second slide rail and the corresponding slider, ensuring that the first machined workpiece group and the second machined workpiece group can rotate synchronously with the rotating shaft, the first cylinder and the second cylinder during the flipping process, ensuring the stability of the flipping process.

[0013] Furthermore, the bottom ends of the first machined workpiece B and the second machined workpiece B both have a V-shaped shovel-like structure, the bottom of the V-shaped shovel-like structure holds up the circuit board and the two edges of the circuit board are respectively tightly clamped in the V-shaped grooves of the V-shaped shovel-like structure on both sides to achieve accurate grasping and clamping positioning of the circuit board.

[0014] Furthermore, a plurality of buffer and anti-collision blocks are arranged on the upper and lower surfaces of the flip plate, which are higher than the clamping mechanism and the cylinder group, and the buffer and anti-collision blocks close to the transmission line are against the frame. Therefore, when the flip device flips to the starting position and flips back to the starting position, the buffer and anti-collision blocks are used for buffering and limiting, reducing the impact noise by 80%, and effectively limiting the flipping position, so as to ensure that the position of each flipping is consistent.

[0015] By using the technical solution of the present invention, the circuit board flipping device has a simple structure, realizes the flipping of the circuit board with relatively low cost, stable structure, smooth operation, low failure rate and low repair cost.

[0024] Similarly, one end of the second machined workpiece group 422 is disposed on the second slide rail 432 and moves along the second slide rail 432 driven by the second cylinder 412 ; the heights of the first machined workpiece group 421 and the second machined workpiece group 422 are adjustable.

[0025] In a specific embodiment of the invention, the first cylinder 411 and the second cylinder 412 respectively drive the corresponding machined workpiece groups (421, 422) to operate stably, and the first slide rail 431 and the second slide rail 434232 can ensure that the operating route of the machined workpiece groups (421, 422) is stable without position deviation, and the relative angle between the machined workpiece groups (421, 422) and other components such as the first cylinder 411 and the second cylinder 412 will not change.

[0026] For example, to prevent the machining workpiece group (421, 422) from being driven by the transmission line or causing wear, preferably, in a specific embodiment of the present invention, a universal wheel 5 is provided on one side of the first machining workpiece group 421 and the second machining workpiece group 422, and the universal wheel 5 is in sliding contact with the transmission line 11, and there is a gap between the first machining workpiece group 421 and the second machining workpiece group 422 and the transmission line 11. In this way, it is ensured that the clamping device 4 can stably clamp the circuit board during the clamping process, and the wear between the entire clamping mechanism 42 and the transmission line 11 can be minimized, thereby reducing unnecessary wear and loss.

[0027] like Figure 1 and 2As shown, preferably, the first machined workpiece group 421 includes a first machined workpiece A4211 and a first machined workpiece B4212 which are arranged up and down and matched and connected by a first adjusting device 423, the first machined workpiece A4211 is arranged on the first slide rail 431 and moves along the first slide rail 431 driven by the first cylinder 411; the first adjusting device 423 includes a first nut group 4231 and a first bolt 4232 which is penetrated through the first machined workpiece A4211 and the first machined workpiece B4212, the first nut group 4231 fixes the first bolt 4232 in the first machined workpiece group 421 and adjusts the distance between the first machined workpiece B4212 and the first machined workpiece A4211; the second machined workpiece group 422 includes a first machined workpiece A4211 and a first machined workpiece B4212 which are arranged up and down and matched and connected by a second adjusting device 424. The second machined workpiece A4221 and the second machined workpiece B4222 are connected, the second machined workpiece A4221 is arranged on the second slide rail 432 and moves along the second slide rail 432 driven by the second cylinder 412; the second adjusting device 424 includes a second nut group 4241 and a second bolt 4242 penetrated through the second machined workpiece A4221 and the second machined workpiece B4222, the second nut group 4241 fixes the second bolt 4242 in the second machined workpiece group 422 and adjusts the distance between the second machined workpiece B4222 and the second machined workpiece A4221; the first machined workpiece B4212 and the second machined workpiece B4222 cooperate to clamp the circuit board on the transmission line, and a universal wheel 5 is provided on one side of the first machined workpiece B4212 and the second machined workpiece B4222. Therefore, through the fixing method of bolts and nuts, the height and front and rear inclination of the clamping mechanism 42 are adjustable, and the clamping device 4 in the gluing and coating adopts the method of cylinder and slide rail, which effectively eliminates the problem of "inward eight" and "outward eight" position relationship after the operation of the first processing workpiece group 421 and the second processing workpiece group 422.

[0028] like Figure 1 and 2 As shown, the first nut group 4231 includes a first nut A42311 fixing the first bolt 4232 on the first machined workpiece A4211, a first nut B42312 fixing the first bolt 4232 on the first machined workpiece B4212, and a first nut C42313 arranged opposite to the first nut B42312; the second nut group 4241 includes a second nut A42411 fixing the second bolt 4242 on the second machined workpiece A4221, a second nut A42412 fixing the second bolt 4242 on the second machined workpiece B, and a second nut A42413 arranged opposite to the second nut A42412. Thus, the effective adjustability of the angle and height position of the clamping mechanism 42 is achieved.

[0029] In a specific embodiment of the present invention, the first adjustment device 423 and the second adjustment device 424 in the clamping mechanism 42 are fixed by bolts and nuts, that is, one bolt is matched with two or more nuts, so as to adjust the angle, up and down position and overall height position of the clamping mechanism 42. Moreover, after the clamping mechanism 42 is fixed, the first machined workpiece B4212 and the second machined workpiece B4222 can be adjusted and ensured to remain parallel to the transmission line 11, and the gap height between the first machined workpiece B4212 and the second machined workpiece B4222 and the transmission line 11 can be effectively adjusted (adjusted according to the thickness of the circuit board), so that after clamping, the circuit board and the transmission line 11 can be separated.

[0030] In order to improve the firmness of each machined workpiece group, preferably, the first machined workpiece group 421 is provided with a plurality of first adjustment devices 423 with the same structure to fix the corresponding first machined workpiece A4211 and the first machined workpiece B4212; the second machined workpiece group 422 is provided with a plurality of second adjustment devices 424 with the same structure to fix the corresponding second machined workpiece A4221 and the second machined workpiece B4222.

Therefore, the slider (431, 432) can be used to limit the position during flipping, and the movement of the upper and lower positions between the first slide rail 431 or the second slide rail 432 and the corresponding slider 6 can be limited. In the specific embodiment of the present invention, taking the first slide rail 431 and the slider 6 as an example, it is obvious that the structural relationship between the second slide rail 432 and the slider 6 is the same as that in the attached figure. Figure 3 Same as in.

[0032] Preferably, if Figure 2 As shown, the first machined workpiece B4212 and the second machined workpiece B4222 both have a V-shaped shovel-like structure 7 at their bottom ends, the bottom of the V-shaped shovel-like structure 7 holds up the circuit board and the two edges of the circuit board are respectively clamped in the V-shaped grooves 71 of the V-shaped shovel-like structure 7 on both sides, so as to achieve accurate grasping and clamping positioning of the circuit board; since the bottom of a conventional circuit board has some small protruding parts, the V-shaped shovel-like structure 7 can be directly inserted under the edges on both sides of the circuit board and hold up the circuit board, thereby holding up and clamping the circuit board.

[0033] Preferably, if Figure 1 As shown, a plurality of buffering and anti-collision blocks 8 are arranged on the upper and lower surfaces of the flip plate 2, which are higher than the clamping mechanism 42 and the cylinder group 41. The buffering and anti-collision blocks 8 on the side close to the transmission line 11 are against the frame 1. The buffering and anti-collision blocks 8 can be polyurethane anti-collision blocks 8 or other anti-collision blocks 8 similar to rubber, plastic, etc. When the flip device 100 flips to a certain position and flips back to a certain position, the buffering and anti-collision blocks 8 are used for buffering and limiting, which reduces 80% of the impact noise, and effectively limits the flipping position, so as to ensure that the flipping position is consistent each time.

[0034] By using the technical solution of the present invention, the entire flip plate 2 can be rotated 180 degrees using the rotating mechanism 3 and the clamping device 4. The flip device 100 has a simple structure, realizes the flipping of the circuit board, has a relatively low cost, a stable structure, and runs smoothly, has a low failure rate, and has a low repair cost.
