As shown in fig. 2, the feeding mechanism 3 includes a movable rail 31 and a fixed rail 33, and the movable rail 31 and the fixed rail 33 extend in the X-axis direction. The movable rail 31 comprises two force arms 32 which are arranged in parallel relatively, a conveying belt is arranged on the force arms 32, and two side edges of the product are respectively arranged on the two conveying belts. Two ends of the transmission belt are respectively provided with a first transmission piece 324, and the first transmission piece 324 is in driving connection with the transmission belt.

The fixed rail 33 is provided with a driving device 332 and a second transmission piece 331, and the driving device 332 can drive the second transmission piece 331 to rotate. The first transmission member 324 can be engaged with the second transmission member 331 so as to drive the transmission belt to rotate.

In this embodiment, the product is a PCB board. Each arm 32 has two overlapped belts along the Z-axis, which are a first belt 321 and a second belt 322. The first belt 321 has a first clamping surface 3211 opposite to the second belt 322; the second strap 322 has a second holding surface 3221 opposite to the first strap 321, a gap is formed between the first holding surface 3211 and the second holding surface 3221, a side edge of the PCB is placed between the first holding surface 3211 and the second holding surface 3221, and the first strap 321 and the second strap 322 are used for holding the PCB.

When the first belt 321 is located below the second belt 322, the first belt 321 rotates to drive the PCB to move, and the cylinder 323 of the first belt 321 drives the first clamping surface 3211 to eject upward in the process. When the second belt 322 is located under the first belt 321, the second belt 322 rotates to drive the PCB to move, and the cylinder 323 of the second belt 322 drives the second clamping surface 3221 to eject upward in the process. The cylinder 323 in the first belt 321 and the second belt 322, in the rotating process, makes the clamping surface driving the PCB board to move upwards and eject, thereby clamping the PCB board more firmly, and making the transportation more stable.

Further, as shown in fig. 8, the cylinder 323 includes an ejection mechanism 3231, a connecting plate 3232, an air duct 3233 and a piston 3234 disposed in the first clamping surface 3211 and/or the second clamping surface 3221, the connecting plate 3232 connects the piston 3234 and the ejection mechanism 3231, the connecting plate 3232 has two horizontal plates disposed horizontally and a vertical plate perpendicular to the horizontal plates, the vertical plate connects the two horizontal plates, and the connecting plate 3232 is substantially in a Z shape.

The air cylinders 323 are uniformly arranged along the extending direction of the first clamping surface 3211 and/or the second clamping surface 3221 to ensure that the ejection distances of the positions of the first clamping surface 3211 and/or the second clamping surface 3221 are the same. Therefore, the PCB can be closer to the horizontal position, and the marking position is more accurate.

Further, a lead screw 5 is arranged between the two force arms 32, and the lead screw 5 extends along the Y-axis direction. At least one of the arms 32 can move along the screw 5 so as to adjust the distance between the two arms 32, and thus can adapt to PCB boards with different sizes.

The turnover mechanism 4 of the automatic double-sided marking machine 100 further comprises a mounting base 41, a turnover motor 42 and a turnover bearing 43. The turning motor 42 is connected to a turning bearing 43 through a belt 44. One end of the roll-over bearing 43 is mounted on the mounting seat 41, the other end of the roll-over bearing 43 is mounted on the force arm 32, and the force arm 32 can rotate around the roll-over bearing 43 by the driving of the roll-over motor 42. Preferably, the tilt bearing 43 is disposed at a middle position of the arm 32, so that the arm 32 is more balanced in weight during the tilting process.

Further, as shown in fig. 3, 4 or 5, the mounting seat 41 further includes a limiting mechanism 4113, and when the moment arm 32 is turned to the horizontal position, the limiting mechanism 4113 can abut against the moment arm 32, so as to determine that the moment arm 32 has been turned over, and prevent the moment arm 32 from being turned over excessively. In this embodiment, the limiting mechanism 4113 is configured as a column, and the two limiting mechanisms 4113 are respectively disposed on two sides of the tilting bearing 43.

As shown in fig. 6 and 7, the flipping motor 42 includes a power output shaft 421 and a flipping output shaft 422, the flipping output shaft 422 includes an outer jaw 4221 and a rod portion 4222, and an inner jaw 423 is embedded in the outer jaw 4221. Specifically, an outer pawl 4221 surrounds an end portion of the power output shaft 421, and the outer pawl 4221 is integrally formed with a rod portion 4222. The inner jaw 423 has a main body portion and a jaw portion provided radially in a circumferential direction of the main body portion, and the main body portion of the inner jaw 423 is provided with a hollow hole. The power output shaft 421 passes through the center hole of the inner jaw 423, the jaw portion of the inner jaw 423 is embedded in the outer jaw 4221, and the outer wall of the body portion of the inner jaw 423 abuts against the inner wall of the outer jaw 4221. The power take-off shaft 421 is also provided with a lock nut 424, and the lock nut 424 is arranged on the other side of the inner jaw 423 away from the outer jaw 4221. A friction plate 425 is provided between the inner pawl 423 and the end surface of the outer pawl 4221, and a similar friction plate 425 is provided between the inner pawl 423 and the locknut 424.

Friction plate 425 can increase the friction between inner jaw 423 and outer jaw 4221 so that power output shaft 421 drives turnover output shaft 422 to rotate. In addition, when the arm of force 32 overturns to the horizontal position, the arm of force 32 abuts against the limiting mechanism 4113, the limiting mechanism 4113 limits the arm of force 32 to overturn excessively, so that the overturning output shaft 422 stops rotating when the arm of force 32 is at the horizontal position, however, the overturning motor 42 cannot stop immediately when the arm of force 32 is at the horizontal position, so that the overturning motor 42 still continues to rotate, and thus, relative rotation can be generated between the power output shaft 421 and the overturning output shaft 422, and abrasion is generated, which is not beneficial to the service life of the overturning motor 42. In the above situation, the friction plate 425 can reduce the friction between the power output shaft 421 and the tumble output shaft 422, and the service life of the tumble motor 42 can be prolonged. In addition, friction plate 425 may provide an amount of play between power take-off 421 and tumble take-off 422 to prevent tumble motor 42 from overloading or losing synchronization.

Preferably, a bowl-shaped washer 4261 and a check washer 4262 are further provided on the power take-off shaft 421, the bowl-shaped washer 4261 and the check washer 4262 are disposed between the locknut 424 and the inner jaw 423, and the bowl-shaped washer 4261 and the check washer 4262 are provided to maintain the torque of the tumble motor 42.

As shown in fig. 5, the mounting base 41 further includes fixing mechanisms 411, the fixing mechanisms 411 are disposed at ends of the moment arm 32, and each fixing mechanism 411 includes an upper fixing member 4111 and a lower fixing member 4112. During the laser marking process, the upper fixing member 4111 and the lower fixing member 4112 hold the force arm 32. In this embodiment, the fixing mechanisms 411 are disposed at two ends of the force arm 32, so that the force arm 32 is fixed on a horizontal plane by the fixing mechanisms 411, thereby achieving that the product is always in a horizontal position in the laser marking process, and improving the accuracy of the laser marking position.

Further, the arm 32 has a protrusion 320 at each end, as shown in fig. 3. The protrusion 320 protrudes in the Y-axis direction and contacts the force arm 32, and the upper fixing member 4111 and the lower fixing member 4112 abut against the protrusion 320. The fixing mechanism 411 further comprises a power mechanism 4110, wherein the power mechanism 4110 can drive the fixing mechanism 411 to move along the X-axis direction, so as to disengage from the protrusion 320, and release the limitation on the force arm 32, so that the force arm 32 can turn over. In this embodiment, the upper fixing member 4111 and the lower fixing member 4112 are provided as pressing wheels, and in other embodiments, may also be provided in the form of pressing blocks, pressing claws, or the like.

Preferably, the mounting base 41 is further provided with a guide rail disposed along the X-axis direction, and the guide rail is between the protrusion 320 and the tilt bearing 43. The fixing mechanism 411 can move along the guide rail under the driving of the power mechanism 4110, so as to be disengaged from the protrusion 320.

In another preferred embodiment, the fixing mechanism 411 further includes a pneumatic motor, which enables the fixing mechanism 411 to move within a small range even though the upper fixing member 4111 and the lower fixing member 4112 can be disengaged from the protrusion 320, so as to release the limitation of the moment arm 32 by the fixing mechanism 411.
