Description

Technical Field

[0001] The invention belongs to the field of electroplating operation auxiliary equipment, and in particular relates to a fully automatic forward and reverse turning material distributing mechanism and a working method. Background Art

[0002] During the operation of the fully automatic unloading machine on the integrated circuit high-speed tinning line, there is a link that automatically takes out the material strips from the magazine and neatly arranges them on the conveyor belt. However, the current loading mechanism adopts a rotating head structure, which directly takes out the products from the magazine and uploads them to the steel belt. There are design defects in the process from taking out to uploading to the conveyor belt. For products placed in the magazine upside down, the production task cannot be carried out normally and manual intervention is required, so the material strips are prone to scratches, warping and other quality problems during the loading process. Summary of the invention

[0003] The purpose of the present invention is to provide a fully automatic positive and negative flip material separation mechanism and a working method thereof, so as to solve the defect that the material separation of positive and negative placed material strips cannot be successful in the prior art.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is:

[0005] Fully automatic forward and reverse flipping material distribution mechanism, including:

[0006] Mounting bracket assembly;

[0007] A first motion mechanism is mounted on the fixed frame assembly;

[0008] An air supply system, comprising a first vacuum generator and a second vacuum generator;

[0009] The third motion mechanism is arranged below the first motion mechanism; a suction cup assembly is arranged at the bottom of the third motion mechanism; two rows of parallel suction nozzles are arranged on the suction cup assembly, namely, a front row suction nozzle and a rear row suction nozzle, the front row suction nozzle is connected to the first vacuum generator through an air pipe, and the rear row suction nozzle is connected to the second vacuum generator through an air pipe;

[0010] A clip is arranged below the suction cup assembly of the third motion mechanism;

[0011] The transmission track assembly and the second motion mechanism are arranged between the clip and the fixing frame assembly.

[0012] A further improvement of the present invention is that: the first motion mechanism comprises an electric actuator fixing plate and an electric actuator; the electric actuator fixing plate is fixed on the fixing frame assembly, and the electric actuator is mounted on the electric actuator fixing plate.

[0013] A further improvement of the present invention is that: the third movable mechanism includes a cylinder fixing plate assembly; the cylinder fixing plate assembly is fixed on the first moving mechanism; a cylinder is installed on the cylinder fixing plate assembly, and the suction cup assembly is installed at the bottom of the cylinder and connected to the moving end of the cylinder.

[0014] A further improvement of the present invention is that: a pair of linear bearings are also provided on the cylinder fixing plate assembly; the pair of linear bearings are arranged on both sides of the cylinder; two optical axes are fixed on the suction cup assembly; the two optical axes pass through the corresponding linear bearings.

[0015] A further improvement of the present invention is that the first vacuum generator and the second vacuum generator are fixed on the cylinder fixing plate assembly.

[0016] A further improvement of the present invention is that the second movable mechanism includes a motor fixing seat, a flap motor is installed on the motor fixing seat, the shaft end of the flap motor is connected to one end of the flap through a coupling, a bearing is installed on the other end of the flap, and the bearing is installed on the fixing seat; the fixing seat is installed on the conveying track assembly; the flap is located next to the conveying track assembly.

[0017] A further improvement of the present invention is that the second movable mechanism is arranged between the fixing frame assembly and the conveying track assembly.

[0018] A further improvement of the present invention is that the third movable mechanism is fixed to the bottom of the electric actuator.

[0019] The working method of the fully automatic forward and reverse flipping material dispensing mechanism includes:

[0020] The third motion mechanism drives the suction cup assembly to contact the material strip in the clip; the first vacuum generator and the second vacuum generator evacuate the vacuum; the suction cup assembly resets to complete the material strip suction operation;

[0021] The first vacuum generator and the second vacuum generator simultaneously perform vacuum signal judgment to determine whether the material strip is forward or reverse;

[0022] If the material strip is judged to be in the forward direction, the first motion mechanism drives the third motion mechanism to the position of the conveying track assembly, the suction cup assembly releases the material strip, and the material strip falls on the track of the conveying track assembly, completing the material separation operation; if the material strip is judged to be in the reverse direction, the first motion mechanism drives the third motion mechanism to the top of the second motion mechanism, the suction cup assembly releases the material strip, and the material strip falls on the second motion mechanism. The second motion mechanism flips the material strip to flip the direction and then falls onto the conveying track assembly, completing the material flipping operation.

[0027] Furthermore, the output shaft of the flap motor drives the flap to flip clockwise 90°-120° through the coupling, and the material strip falls into the guide rail of the conveying track assembly after flipping the direction, completing the flipping operation.
