A comprehensive packaging system for an LED screen and a method for packaging the same. The packaging steps are as follows:

S1: Place the LED raw material on the conveyor belt of the raw material conveyor, place the top cover of the plastic injection mold on the conveyor belt of the top cover conveyor, and place the plastic injection mold base on the conveyor belt of the bracket conveyor. The material is conveyed to the feeding end of the plastic injection workbench, and then the rotation of the displacement structure drives the long shaft to rotate under the transmission action of the first transmission structure. At this time, the chain of the first transmission structure is in a circular rotation state, and Due to its fixed connection with the moving assembly, it can drive the moving assembly to move laterally left and right. At the same time, the drive motor drives the push rod plate screw to rotate, and under the transmission action of the push rod plate screw and the threaded sleeve, it can drive the push rod plate screw to rotate. The push rod mounting plate moves forward and backward, and the clamping structure moves and adjusts accordingly, and the extension and retraction of the electric push rod can drive the clamping structure to adjust the vertical height, grab or put down the workpiece. At this time, the clamping structure can perform multiple functions. To move in the direction, the clamping structure first grabs the plastic injection mold base to the plastic injection workbench, then grabs the support conveyor and puts it into the mold cavity of the plastic injection mold base, and finally puts the plastic injection mold top cover. Covered on the top of the base of the plastic injection mold, at this time, mechanized automatic feeding is realized, without manual continuous feeding operation, which effectively reduces the manual assistance involved, and one clamping structure can complete the grasping of three different workpieces. Pick and place, without the coordinated use of multiple manipulators, reducing the cost of use and production;

S2: The grabbing steps of the specific clamping structure are as follows: when grabbing the base of the injection mold and the top cover of the injection mold, the base of the injection mold and the top cover of the injection mold are sucked and grasped by a vacuum suction cup, and the pneumatic motor is used for adsorption and grabbing. 2. The transmission structure 2 drives the transmission shaft to rotate, and the transmission structure 3 provided at both ends of the transmission shaft drives the suction cup mounting plate screw and the pneumatic mounting plate unit screw to rotate at the same time. Both the screw and the pneumatic parts mounting plate are driven by thread. When the suction cup mounting plate moves down, the pneumatic parts mounting plate moves up. Make the sucker mounting plate screw go into and out of the mounting frame through the inlet and outlet, then close the solenoid valve one near the pneumatic pipeline, and open the solenoid valve one far away from the pneumatic pipeline. The pressure is conducted by the metal hose and the suction cup pipeline in turn, thereby realizing the adsorption of the workpiece. When the LED raw material needs to be clamped, the pneumatic component mounting plate is lowered, the suction cup mounting plate is raised, and then the electromagnetic close to the pneumatic pipeline is turned on. Valve 1, close the solenoid valve 1 away from the pneumatic pipeline, the air pump continuously delivers gas to the inside of the pneumatic pipeline through the T-shaped connecting pipe, the gas enters the inside of the sleeve shell through the pneumatic pipeline, and sends the piston plate to the telescopic rod. Push on one side, the pneumatic push block will compress the strong spring, when the LED raw material is located between the two clamps, the air pump stops working, the solenoid valve 2 is opened to release the gas inside the sleeve shell, and the elastic reset of the guide rod Then, the two clamps move to the LED raw material, and then the LED raw material is clamped by the two clamps, thus realizing a clamp device, which can switch between two different clamping methods, thereby realizing the clamping mode for different materials. At the same time, due to the negative pressure and pneumatic methods used, one air pump is used for use, which further reduces the cost;

S3: When the base of the injection mold is placed on the top of the injection table, the sliding seat is in contact with the sliding rails of the bracket, and the sliding contact between the sliding seat and the sliding rails of the bracket is not only easy to push and move it, but also to the sliding rails of the bracket. The position plays a limited role, which is beneficial to ensure the stability of the package. Then, the driving motor three drives a sprocket shaft to rotate. Under the transmission action of the transmission structure four, the two sprocket shafts rotate at the same time, and the protruding plate is also pushed at this time. Circular rotation, when the protruding plate rotates, it will contact and block the protruding block. At this time, due to the thrust of the protruding plate, the sliding guide rail of the bracket is driven to move in the direction of the baking structure, and under the action of the thrust, it drives the glue injection. The mold base moves forward one by one to ensure the stability of the movement, and it is not easy to slip backwards. When the injection port of the top cover of the injection mold is located directly below the outlet of the injection structure, the The glue gun injects glue into the mold cavity to realize glue filling;

S4: In addition, the glue filling and long baking are carried out in a mechanized way, without manual auxiliary coordination, which is conducive to improving work efficiency. The top of the top cover of the mold gradually squeezes the mold seat, which is conducive to the tightness of the contact between the top cover of the injection mold and the base of the injection mold, thereby improving the effect of injection molding, reducing the defective rate and improving the efficiency. .

The conveyor conveys the material to the feeding end of the plastic injection table, and then the rotation of the displacement structure drives the long shaft to rotate under the transmission action of the transmission structure 1. At this time, the chain of the transmission structure 1 is in a circular rotation state. , and because of its fixed connection with the moving assembly, it can drive the moving assembly to move laterally left and right. At the same time, the drive motor drives the push rod plate screw to rotate, under the transmission action of the push rod plate screw and the threaded sleeve, The push rod mounting plate can be driven to adjust the front and rear movement, and the clamping structure can be moved and adjusted accordingly, and the extension and retraction of the electric push rod can drive the clamping structure to adjust the vertical height, grab or put down the workpiece. At this time, the clamping structure can be adjusted. To move in multiple directions, the clamping structure first grabs the plastic injection mold base onto the plastic injection workbench, then grabs the support conveyor and puts it into the mold cavity of the plastic injection mold base, and finally puts the plastic injection mold into place. The top cover is placed on the top of the base of the injection mold.

The screw of the plate unit and the mounting plate of the pneumatic parts are driven by thread. When the mounting plate of the suction cup moves downwards, the mounting plate of the pneumatic parts moves upward. On the contrary, the mounting plate of the suction cup is upward, the mounting plate of the pneumatic parts is downward, and the mounting plate of the suction cup is downward. Move and make the sucker mounting plate screw enter and exit the inside of the mounting frame through the inlet and outlet, then close the solenoid valve 1 close to the pneumatic pipeline, and open the solenoid valve 1 away from the pneumatic pipeline. When the vacuum suction cup is in contact with the workpiece, the air pump will inhale , the negative pressure is conducted by the metal hose and the suction cup pipeline in turn, so as to realize the adsorption of the workpiece. When the LED raw material needs to be clamped, the pneumatic parts mounting plate descends, the suction cup mounting plate rises, and then opens and closes the pneumatic pipeline. 1. Close the solenoid valve 1 away from the pneumatic pipeline. The air pump continuously delivers gas to the inside of the pneumatic pipeline through the T-shaped connecting pipe. One side of the rod is pushed, and the pneumatic push block will compress the strong spring. When the LED raw material is located between the two clamps, the air pump will stop working, and the second solenoid valve will be opened to release the gas inside the sleeve shell, and it will be released on the guide rod. Under the elastic reset, the two clamps move towards the LED raw material, and then the LED raw material is clamped by the two clamps, thus realizing a clamp device, which can switch two different clamping methods, thereby realizing the clamping of different materials At the same time, due to the negative pressure and pneumatic methods, one air pump is used for use, which further reduces the cost.

3. In the present invention, when the base of the injection mold is placed on the top of the injection table, the sliding seat is in contact with the sliding guide rail of the bracket, and the sliding contact between the sliding seat and the sliding guide rail of the bracket is not only convenient for pushing and moving it, but also for the bracket. The position of the sliding guide rail plays a limited role, which is beneficial to ensure the stability of the package. Then, the drive motor three drives a sprocket shaft to rotate. Under the transmission action of the transmission structure four, the two sprocket shafts rotate at the same time. At this time, the convex plate is pushed It also rotates in a circular shape. When the protruding plate is rotated, it will contact and block the protruding block. At this time, the thrust of the protruding plate drives the sliding guide rail of the bracket to move in the direction of the baking structure. The base of the injection mold moves forward one by one to ensure the stability of the movement, and it is not easy to slip backwards. When the injection port of the top cover of the injection mold is located directly below the outlet of the injection structure, the injection structure The glue gun above injects glue into the mold cavity to realize glue filling.

4. The mold after the glue filling of the present invention is completed will be pushed to the inside of the baking structure by the rear mold, and finally the mold will be subjected to long baking inside the baking structure, thereby realizing the integrated operation of glue filling and long baking, and Both the glue filling and the long baking are carried out in a mechanized way, without manual auxiliary coordination, which is beneficial to improve the work efficiency. The top of the injection mold gradually extrudes the mold seat, which is conducive to the tightness of the contact between the top cover of the injection mold and the base of the injection mold, thereby improving the effect of injection molding, reducing the defective rate and improving the efficiency.
