[0027] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0028] See also Figure 1 and Figure 2 , this embodiment provides a shield cover automatic assembly machine, including a machine platform 1, on which a shield cover storage area for storing shield covers, an assembly area for assembling shield covers to products, and a feeding mechanism for conveying products are provided;

[0029] Among them, the assembly area is provided with a feed track changing mechanism 2, a finished product feeding and discharging mechanism 3, and a shielding cover opening mechanism 4 in sequence along the conveying direction of the feeding mechanism; the shielding cover storage area has a translation mechanism 5 for moving the shielding cover to the side of the shielding cover opening mechanism 4 and a feeding mechanism 6 for transferring the shielding cover to the shielding cover opening mechanism 4, the feeding mechanism includes a feed track 7 and a product conveying belt 8 intersecting head to tail, and the feed track changing mechanism 2 is arranged at the intersection of the feed track 7 and the product conveying belt 8; wherein, a two-way material dividing mechanism 9 is arranged on the opposite side of the feeding mechanism 6 to separate the products conveyed by the feeding mechanism and then convey them to the shielding cover opening mechanism 4, and the feeding mechanism 6 has the same structure as the two-way material dividing mechanism 9;

[0030] To sum up, when working, the translation mechanism 5 moves the tray with the shielding cover to the bottom of the loading mechanism 6. At this time, the product is transported to the feeding track 7 to the feeding track changing mechanism 2, and the feeding track changing mechanism 2 transfers the product to the product conveying belt 8. The product conveying belt 8 transports the product to the two-way dividing mechanism 9, and the two-way dividing mechanism 9 separates each product into intervals and transfers them to the shielding cover opening mechanism 4. At the same time, the loading mechanism 6 transfers the shielding cover to the shielding cover opening mechanism 4, and the shielding cover opening mechanism 4 assembles the product into the shielding cover. The assembly is completed automatically with high efficiency.

[0031] For details, please refer to Figure 3The feed rail changing mechanism 2 includes a truss 20 with a slide rail group and a first slide cylinder 22 which is slidably mounted on the slide rail group and has a fine-tuning component 21 at the output end, and a plurality of first air claws 23 are arranged side by side on the fine-tuning component 21; wherein the fine-tuning component 21 includes a support bracket 210 which is mounted on the first slide cylinder 22 and is driven to move up and down by the first slide cylinder 22, a guide rail group is horizontally arranged on the support bracket 210, a plurality of first air claws 23 are slidably mounted on the guide rail group, and a pull block 211 with a hook is arranged on the top of each first air claw 23, and a pull block 211 at one end away from the hook is arranged on the pull block 211. A protrusion is provided, and the hook on each pulling block 211 extends to the adjacent pulling block 211. The supporting bracket 210 is provided with a telescopic cylinder 212 whose output end is connected to the pulling block 211 at the end. When the telescopic cylinder 212 pulls the connected first air claw 23, the protrusion blocks the hook, so that when the telescopic cylinder pulls the connected first air claw 23, the other first air claws 23 are also pulled. Since there is a sliding distance between the hook and the protrusion, it can be adjusted according to the different sizes of the products. The distance between each first air claw 23 meets the transportation of products of different sizes, and it is highly practical.

[0032] See also Figure 4 The shielding cover storage area also includes a pallet storage area surrounded by a plurality of profiles 11, each profile 11 is provided with a pallet positioning assembly 12, and a translation mechanism 5 is provided below the pallet storage area; wherein, the translation mechanism 5 mainly transports the pallet equipped with the shielding cover to the bottom of the feeding mechanism 6, and the translation mechanism 5 includes a transverse moving module 50 and a receiving lifting assembly 51 provided on the transverse moving module 50, and a pallet fixture is provided at the lifting end of the receiving lifting assembly 51, and a pallet limiting telescopic assembly 52 is provided at the end of the transverse moving module 50 close to the side of the shielding cover opening mechanism 4. When working, the transverse moving module 50 is used to move the pallet to the bottom of the feeding mechanism 6. The module 50 moves the receiving lifting component 51 to the bottom of the pallet storage area. After the receiving lifting component 51 rises to the set distance, the pallet positioning components 12 on all sides are opened, so that the bottom pallet falls on the receiving lifting component 51. After unloading is completed, the pallet positioning components 12 on all sides are started again to block the second to last pallet, and the receiving lifting component 51 moves downward. The pallet on the receiving lifting component 51 is transferred to the side of the shielding cover opening mechanism 4 by the horizontal moving module 50, and the pallet limiting telescopic component 52 is started to fix the pallet on the pallet fixture to prevent the pallet from moving when the feeding mechanism 6 grabs the material.

[0033] For details, please refer to Figure 5 and Figure 6The feeding mechanism 6 and the two-way material distribution mechanism 9 are mainly used for conveying shielding covers and products. The feeding mechanism 6 and the two-way material distribution mechanism 9 have the same structure, and both include a mobile frame 90 and a lifting plate 91 that can move up and down and is arranged on the mobile frame 90. A horizontal slide rail group is horizontally arranged on the lifting plate 91, and a plurality of second air claws 92 are slidably arranged on the horizontal slide rail group. A limiting block 93 is arranged on the upper end of each second air claw 92, and a buckle 94 is formed on each limiting block 93 extending toward the adjacent second air claw 92, and a stopper 95 cooperating with the buckle 94 is arranged on the limiting block 93 of each second air claw 92, and a stopper 95 cooperating with the buckle 94 is arranged on the lifting plate 91. On the contrary, the output end of the dividing cylinder 96 is connected to the second air claws 92 at the ends of both sides, and the movable frame 90 is provided with a lifting stroke cylinder 97 for pushing the lifting plate 91 to move. When working, the lifting stroke cylinder 97 drives the lifting plate 91 to move downward, so that the second air claws 92 grab the product or the shielding cover. After grabbing, the lifting stroke cylinder 97 drives the lifting plate 91 to reset. At this time, the dividing cylinder 96 is started, so that each second air claw 92 is spaced apart to realize the separation of the shielding cover and the product. Through the above arrangement, each product and shielding cover can be spaced apart, so that the product and the shielding cover can be placed on the shielding cover opening mechanism 4 for product and shielding cover assembly.

[0034] In addition, the feeding mechanism 6 and the two-way feeding mechanism 9 also include a frame 98 straddling the machine 1, and a group of longitudinal slide rails are arranged on the frame 98.

The shielding cover opening mechanism 4 includes a slide 40 and a product pushing component 41 slidably arranged on the slide 40 for pushing the product into the shielding cover, and a shielding cover installation fixture arranged on the product pushing component 41.

The forward pushing component 42 is provided with an opening air claw 43 for opening the shielding cover in the shielding cover installation fixture and a pressing plate 44 for preventing the shielding cover from being opened too much. The slide 40 is provided with a mechanism transverse movement cylinder 45 for driving the product pushing component 41 to move to the finished product feeding and discharging mechanism 3. The product pushing component 41 is arranged between the feeding mechanism 6 and the two-way material dividing mechanism 9. During assembly, the two-way material dividing mechanism 9 transfers the product to the product pushing component 41, and the feeding mechanism 6 transfers the shielding cover to the shielding cover installation fixture. When the air claw 43 is opened, the product pushing component 41 pushes the product into the shielding cover for a certain distance, and then the product pushing component 41 stops pushing, the air claw 43 is closed, and the forward pushing component 42 drives the air claw 43 to retreat, so that the air claw 43 and the pressure plate 44 are separated from the shielding cover. After the air claw 43 and the pressure plate 44 exit the shielding cover, the product pushing component 41 is started again to push the product again so that the product is completely assembled into the shielding cover. After the assembly is completed, the mechanism transverse cylinder 45 moves the product pushing component 41 to the finished product feeding and discharging mechanism 3, and the finished product feeding and discharging mechanism 3 discharges the product.

The third air claw 32 is driven by the longitudinal moving module 30 to move above the product pushing component 41, and then the third air claw 32 is driven downward by the second slide cylinder 31 to make the third air claw 32 grab the product assembled on the product pushing component 41, and then the third air claw 32 with the product is driven by the longitudinal moving module 30 to move to the product conveying belt 8 or the defective product conveying belt 33. The product conveying belt 8 conveys the good products out of the equipment, and the defective product conveying belt 33 conveys the defective products out of the equipment.

[0037] Furthermore, in this embodiment, the automatic assembly machine for shielding cover further comprises a product jig recovery lifting mechanism 10 intersecting with the discharge end of the feed track 7, and the product jig recovery lifting mechanism 10 is mainly used to transport the product jig out of the device, see Fig. 9 The product jig recovery lifting mechanism 10 includes a vertical moving module 100 and a jig receiving conveyor belt 101 arranged on the vertical moving module 100. The vertical moving module 100 drives the jig receiving conveyor belt 101 to be flush with the discharge end of the feed track 7. When the feed track changing mechanism 2 transports the product on the feed track 7 to the product conveying belt 8, the feed track 7 transports the product jig to the jig receiving conveyor belt 101, and the vertical moving module 100 descends to the inside of the machine 1. A box is placed in the machine 1 below the vertical moving module 100. After the vertical moving module 100 descends, the jig receiving conveyor belt 101 is started to make the product jig fall into the box to complete the recovery of the product jig. After unloading the product jig, the vertical moving module 100 raises the jig receiving conveyor belt 101 to be flush with the discharge end of the feed track 7 to facilitate receiving the next product jig.
