When the dispensing product storage rack 8 is lifted, the four unloading lifting rods 725 are flush. When the unloading lifting cylinder 722 continues to extend, the four unloading lifting rods 725 cooperate with the second column 801 on the dispensing product storage rack 8 for lifting;

[0068] The lower surface of the material unloading jacking fixed plate 724 is diagonally fixedly connected with two material unloading positioning cylinders 726, the output end of the material unloading positioning cylinder 726 is fixedly connected to the diagonal material unloading jacking rod 725, and the top of the material unloading jacking rod 725 is formed with a conical material unloading guide section 727, and the four internal corners of the material unloading jacking frame 721 are fixedly connected with material unloading guide rods 728, the material unloading jacking fixed plate 724 is slidably sleeved on the outer surface of the material unloading guide rod 728, and a material unloading sensor 729 is installed on the material unloading jacking frame 721, which drives the diagonal material unloading jacking rod 725 to extend through the unloading positioning cylinder 726. The two unloading lifting rods 725 move upward, and due to the existence of the unloading guide section 727, they can be guided when inserted into the unloading lifting through hole 904, and the unloading transfer trolley 9 is positioned again. After the unloading sensor 729 detects that there is a storage rack 8 for the completed product with dispensing at the bottom, the storage rack 8 for the completed product with dispensing is pushed upward, and the storage rack 8 for the completed product with dispensing is supported by the unloading reset clip 903, and this process is repeated until the unloading sensor 729 at the top detects that the storage rack 8 for the completed product with dispensing is full, and then the unloading transfer trolley 9 can be moved away.

[0069] like Fig.16As shown: In this embodiment, the storage rack 8 for finished glue dispensing products includes four second columns 801, two second layer plates 802 are fixedly connected between the four second columns 801, and a plurality of slots 803 for finished glue dispensing products are opened on the second layer plates 802.

[0070] like Figure 17-19 As shown: In the present embodiment, the material unloading transfer trolley 9 comprises a material unloading transfer frame 901 and a material unloading port 902 opened on the front of the material unloading transfer frame 901, a plurality of material unloading reset clips 903 are installed on the inner walls on both sides of the left and right sides of the material unloading transfer frame 901, and a plurality of storage racks 8 for finished glue dispensing products can be stacked through the material unloading reset clips 903, and four material unloading lifting through holes 904 are opened on the lower surface of the material unloading transfer frame 901, and a plurality of material unloading universal balls 905 are installed on the lower surface of the material unloading transfer frame 901, and a material unloading door panel 907 is installed at the material unloading port 902 of the material unloading transfer frame 901 through a material unloading hinge 906, and the material unloading door panel 907 is closed through the material unloading hinge 906 after loading is completed, and the storage racks 8 for finished glue dispensing products stored inside are limited, and a material unloading QR code 908 is arranged on the top of the front of the material unloading transfer frame 901, and the information of the finished glue dispensing products can be scanned through the material unloading QR code 908;

[0071] The material unloading reset clip 903 includes two second reset rods 9031 fixedly connected between the inner walls of the front and rear sides of the material unloading transfer frame 901. The outer surface of the lower second reset rod 9031 is rotatably connected to the second support block 9033 through a second torsion spring 9032. The other end of the second support block 9033 is formed with a second limiting portion 9034 that cooperates with the other second reset rod 9031.

[0072] After the storage rack 8 for the finished glue dispensing products is pushed upward, the storage rack 8 for the finished glue dispensing products squeezes the second support block 9033, rotates around the second reset rod 9031 and compresses the second torsion spring 9032, until the storage rack 8 for the finished glue dispensing products at the bottom is moved to the upper side unloading reset clip 903, and then the unloading lifting cylinder 722 retracts the unloading lifting rod 725 to the inner bottom wall of the unloading transfer rack 901. At this time, due to the action of gravity and the restoring force of the second torsion spring 9032, the second support block 9033 is restored to an oblique upward position and supports the storage rack 8 for the finished glue dispensing products.

[0073] Working principle: First, place the product to be dispensed in the product slot 203 of the product storage rack 2, and place multiple product storage racks 2 full of products on the discharge reset clip 103 on the discharge transfer rack 101. Then close the discharge door 107 through the discharge hinge 106 and other equipment or manual methods to limit the internal multiple storage racks 2 for dispensing products. Then, move the dispensing products through the discharge universal ball 105 at the bottom of the discharge transfer trolley 1. The material discharging trolley is initially positioned in the positioning groove 303, and then the material discharging positioning cylinder 306 is started to extend and drive the two diagonal material discharging lifting rods 305 to move upward. Due to the existence of the material discharging guide section 307, it will be inserted into the material discharging lifting through hole 104, so that the material discharging transfer trolley 1 can be positioned again to ensure that the positions of the storage rack 2 for the product to be dispensed and the product are accurate. Then, the material discharging door panel 107 is opened, and the material taking electric slide 310 is extended to drive the material taking platform 311 to take out the top storage rack 2 for the product to be dispensed;

[0074] Then, when in use, the mechanical arm connecting rod 411 on the material grabbing fixing plate 401 is connected to the external mechanical arm, and then the material grabbing mechanical arm 4 is moved to the top of the product storage rack 2 for the product to be glued. At this time, the storage rack clamping claw 407 is in an open state, and then the material grabbing cylinder 404 extends to drive the storage rack clamping claw 407 to move downward to the storage rack 2 for the product to be glued, and then the material clamping cylinder 406 contracts to drive the material grabbing cylinder 404 and the connecting seat 403 to rotate around the first pin shaft 402. At this time, the storage rack clamping claws 407 on the left and right sides clamp and fix the storage rack 2 for the product to be glued, and then the external mechanical arm stores the product to be glued. The rack 2 moves to the top of the positioning rack 502, and then the product storage rack 2 to be glued is placed on the positioning rack 502 by the material grabbing cylinder 404 and the material clamping cylinder 406, and then the cylinder connected to the positioning block 503 is extended to push the product storage rack 2 to contact with the four positioning columns 504 for positioning, and then the two product clamping claws 409 on the double-claw cylinder 408 are controlled to clamp and fix the product to be glued on the product storage rack 2, and then move to the four rotating claws 509, and then the product is clamped and fixed by the rotating cylinder 508, and then the motor 507 rotates to rotate the clamped product 180 degrees;

[0075] Then the external robot arm moves the product to be dispensed to the surface of the adsorption head 604. Due to the obstruction of the product, the photoelectric receiving end of the second sensor 606 cannot receive the signal of the photoelectric transmitting end. At this time, the negative pressure generator 601 generates negative pressure; the product is initially adsorbed on the adsorption head 604, and the negative pressure causes the adsorption head 604 of the bellows to contract, so that the product adsorbed on the adsorption head 604 moves toward the guide ring 608, and the edge of the product contacts the guide slope 609, thereby correcting the slight deviation of the product on the adsorption head 604; at the same time, the adsorption head 604 of the bellows acts as a buffer for the product. When the product moves into place, the light of the second sensor 606 The electrical receiving end receives the signal from the photoelectric transmitting end, and then starts the dispensing rotating motor 602 to drive the dispensing platform 603 and the product to rotate. During the rotation, the dispensing head is located above the dispensing platform 603 to complete the dispensing of the product. Finally, the negative pressure generator 601 loosens the product, and then the material grabbing manipulator 4 places the dispensing product storage rack 8 on the right side of the conveyor belt 702. Then the first cylinder 709 drives the positioning block 710 and the positioning wheel 711 to extend. At this time, the positioning wheel 711 pushes the dispensing product storage rack 8 against the four positioning rods 707, and then the dispensing product is transferred to the dispensing product slot 803 on the dispensing product storage rack 8 through the material grabbing manipulator 4.

[0076] During loading, the material transfer trolley 9 is moved into the material transfer trolley positioning groove 723 for preliminary positioning through the material transfer universal ball 905 at the bottom of the material transfer rack 901. At this time, the material transfer trolley 9 is in an open state, and the storage racks 8 of the glue-dispensing products can be placed into the material transfer trolley 9 one by one. Then, the material positioning cylinder 726 is started to extend and drive the two diagonal material lifting rods 725 to move upward. Due to the existence of the material guide section 727, it can be guided when inserted into the material lifting through hole 904, and the material transfer trolley 9 is positioned twice to ensure The position of the material transfer trolley 9 is accurate, and then the visual inspection camera 708 detects the dispensing product slot 803 on the dispensing product storage rack 8, so that the material grabbing robot 4 fills the dispensing products in the entire dispensing product slot 803 in sequence, and then the first cylinder 709 contracts and releases the dispensing product storage rack 8, and then the conveyor belt 702 is started to move the dispensing product storage rack 8 to the left, and then the pushing cylinder 704 drives the pushing block 705 to move downward, and then the material unloading electric slide 703 drives the pushing block 705 to move left to move the dispensing product The product storage rack 8 is pushed into the interior of the material transfer trolley 9. When the material dispensing sensor 729 detects that the product storage rack 8 is completed by dispensing, the material dispensing lifting cylinder 722 extends to drive the material dispensing lifting fixing plate 724 and the four material dispensing lifting rods 725 to move upward. At the same time, the material dispensing positioning cylinder 726 contracts, driving the two diagonal material dispensing lifting rods 725 to move downward, so that the four material dispensing lifting rods 725 are flush, and then the material dispensing lifting cylinder 722 continues to extend, and the four material dispensing lifting rods 725 cooperate with the second column 801 on the product storage rack 8 for dispensing. The glue-finished product storage rack 8 is pushed upward, and at this time, the glue-finished product storage rack 8 squeezes the second support block 9033 to rotate around the second reset rod 9031 and compress the second torsion spring 9032, until the glue-finished product storage rack 8 at the bottom is moved to the upper side unloading reset clip 903, and then the unloading lifting cylinder 722 retracts the unloading lifting rod 725 to the inner bottom wall of the unloading transfer rack 901. At this time, due to the action of gravity and the restoring force of the second torsion spring 9032, the second support block 9033 is restored to an oblique upward position, and the glue-finished product storage rack 8 is supported;

[0077] Then the discharging electric slide 309 moves downward, and then the picking electric slide 310 extends to drive the picking platform 311 to take out the storage rack 2 of the product to be dispensed on the lower side, and finally the discharging lifting cylinder 302 is started to extend to drive the discharging lifting fixed plate 304 and the four discharging lifting rods 305 to move upward, and at the same time, the discharging positioning cylinder 306 contracts, driving the two diagonal discharging lifting rods 305 to move downward, so that the four discharging lifting rods 305 are flush, and then the discharging discharging lifting cylinder 302 continues to extend, through the four discharging lifting rods 305 and the dispensing product to be dispensed The first column 201 on the glue product storage rack 2 cooperates to push the glue product storage rack 2 upward. At this time, the glue product storage rack 2 squeezes the first support block 1033 to rotate around the first reset rod 1031 and compresses the first torsion spring 1032 until the glue product storage rack 2 at the bottom is moved to the top. At this time, the restoring force of the first torsion spring 1032 restores the first support block 1033 to an oblique upward position. Finally, the discharging electric slide 309 and the picking electric slide 310 cooperate with the picking platform 311 to take out the lifted glue product storage rack 2;

[0078] Then, glue dispensing is carried out through the cooperation of the grabbing robot 4, the positioning platform 5 and the glue dispensing fixture 6. Finally, the unloading electric slide 703 drives the push block 705 to move the next glue-dispensing completed product storage rack 8 into the interior of the unloading transfer trolley 9. The unloading lifting cylinder 722 pushes the bottom glue-dispensing completed product storage rack 8 upward again. The unloading, glue dispensing and unloading are repeated in this way until the unloading sensor 729 detects that the glue-dispensing completed product storage rack 8 is full. The unloading door panel 907 can be closed by other equipment or manual methods, and finally the unloading transfer trolley 9 can be moved away.

[0079] All technical features in this embodiment can be freely combined according to actual needs.
