When the material receiving device is used, the display screen 41 is sequentially cleaned by the cleaning machine and dried by the drying machine through the conveyor belt 3, then the display screen 41 is conveyed to the end area of the conveyor belt 3 by the conveyor belt 3, the material receiving rod 15 moves back and forth between the two sides of the material receiving frame 2 under the driving of the third air cylinder 12 to push the display screen 41 out of the conveyor belt 3, the display screen 41 penetrates through the material receiving grooves on the two sides of the material receiving frame 2 and falls on the material receiving pad 17, the material receiving block 16 simultaneously penetrates through the material receiving grooves when the display screen 41 is pushed, so that the display screen 41 is prevented from being lapped on the material receiving grooves, the material receiving block 16 and the material receiving pad 17 are both made of rubber materials, and have elasticity and do not deform, when the display screen 41 falls on the material receiving pad 17, the material receiving pad 17 prevents the display screen 41 from being damaged, and enables each display screen 41 to just stop at a fixed position, and is convenient to receive;

then the first air cylinder 7 moves the first sliding block 5, the first support 9 is moved to the position right above the display screen 41, the first electric push rod 18 extends, the sucker mechanism is put down, the material receiving sucker 22 is driven to move downwards by the sucker seat 20, when the material receiving sucker 22 is contacted with the display screen 41, the sucker seat 20 is temporarily stopped to be pressed downwards, the sucker air cylinder 21 is matched with the hose, so that the suction force is generated at the position of the material receiving sucker 22, the material receiving sucker 22 fixes the display screen 41, and then the first electric push rod 18 contracts to lift the display screen 41;

simultaneously, the second electric push rod 19 extends, the clamping mechanism 11 is put down, the driving motor 24 rotates the driving gear 25, the driving gear 25 is respectively meshed with the four driven gears 26 for transmission, so that the driving shaft 27 is rotated, the wire barrel 28 is rotated, the driving wire 29 is pulled, the driving block 39 is pulled, the coil spring barrel 38 is rotated, the clamping piece 40 is rotated, the clamping mechanism 11 is opened, then the clamping mechanism 11 is pushed by the second electric push rod 19 to move to the upper side of the storage rack 42, then the driving motor 24 rotates reversely, so that the driving wire 29 loosens the coil spring barrel 38, the coil spring barrel 38 rebounds, the clamping piece 40 is rotated to approach the mounting box 32, the clamping piece 40 clamps the edge of the storage rack 42, the storage rack 42 is clamped, and then the second electric push rod 19 contracts and the storage rack 42 is lifted;

then the second cylinder 8 moves the second slide block 6 to the middle of the supporting guide rail 4, the storage rack 42 is put down, the clamping and taking of the storage rack 42 is continued, then the first cylinder 7 moves the first slide block 5 to the middle of the supporting guide rail 4, the display screen 41 is placed on the storage rack 42, the whole process from cleaning to storage of the display screen 41 is completed, the actions are repeated, the storage racks 42 are overlapped one by one through the clamping and taking mechanism 11, the display screen 41 is overlapped into a stack while being stored, and the carrying mechanism is convenient to carry;

through mutually supporting of each part for the conveyer belt 3 can be uninterruptedly from the production end to receiving the material end and carry display screen 41, avoid because nobody accomodate display screen 41 and make the gathering of display screen 41 cause the accident at the tip of conveyer belt 3, prevent simultaneously that display screen 41 from removing to fall behind the tip of conveyer belt 3, more need not the manual work and accomodate labour saving and time saving.

Although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
