[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0023] An intelligent barcode automatic recognition device, such as Figure 1 and Figure 2 As shown, it includes a frame 1, several conveying rollers 2, a gantry 3 and several barcode identifiers 4. Several conveying rollers 2 are rotatably installed on the frame 1. Several conveying rollers 2 include unpowered rollers 21 and electric rollers 22. The unpowered rollers 21 and the electric rollers 22 are evenly distributed. The even distribution of the unpowered rollers 21 and the electric rollers 22 can not only ensure the conveying effect but also save costs. When the conveying capacity needs to be improved, it is only necessary to increase the number of electric rollers 22. A multi-V belt is commonly provided between the adjacent conveying rollers 2. The contact area and friction between the multi-V belt and the pulley are large, and the load is more evenly distributed along the bandwidth, so the transmission capacity is greater. The multi-V belt also has the characteristics of small transmission vibration, fast heat dissipation, smooth operation, small elongation in use, large transmission ratio and high limit linear speed. The multi-V belt can transmit the power of the electric roller 22 to the unpowered roller 21. At the same time, the multi-V belt can also synchronize the transmission speeds of all rollers to ensure conveying stability.

[0024] like Figure 1 and Figure 6As shown, a gantry 3 is provided above the frame 1, and a plurality of barcode identifiers 4 are fixedly mounted on the gantry 3. The barcode identifier 4 includes an optical module 41, a photoelectric conversion module 42, a decoding circuit module 43, a computer interface 44 and a fill light 45. The fill light 45 provides fill light illumination to the barcode area of the object to be identified during barcode recognition to improve recognition accuracy. The optical module 41 scans the barcode and receives the reflected information. The photoelectric conversion module 42 converts the optical signal into an electrical signal and sends it to the decoding circuit module 43. The decoding circuit module 43 decodes the electrical signal into data that can be recognized and processed by the computer and sends it to the computer through the computer interface 44. The computer controls other devices according to the information content.

[0025] like Figures 1 to 3 As shown, a lifting frame 5 is installed on the right side of the gantry 3 for sliding up and down. A plurality of electric lifting cylinders 51 are fixedly installed on the lower end of the lifting frame 5 and the gantry 3. A turning frame 6 is rotatably installed on the left side of the lifting frame 5. The rotating shaft of the turning frame 6 passes through the lifting frame 5 and is connected to a turning motor 61 through a gearbox; after the electric lifting cylinder 51 jacks up the lifting frame 5, the turning motor 61 turns the turning frame 6 to prevent the clamping claw embedded in the conveyor belt from colliding with the conveyor belt; a positive and negative screw rod 62 is provided in the turning frame 6, and a limit block 63 is sleeved in the middle of the positive and negative screw rod 62. The limit block 63 is fixedly installed in the turning frame 6. The limit block 63 prevents the clamping claw from colliding with each other and damaging the equipment. The upper end of the positive and negative screw rod 62 passes through the turning frame 6 and is connected to a pitch-adjusting motor 67. A counterweight block 68 for balancing the pitch-adjusting motor 67 is fixedly installed at the lower end of the turning frame 6. The counterweight block 68 has the same weight as the pitch-adjusting motor 67, so that the turning frame 6 is more stable when turning, reducing the wear of the rotating shaft of the turning frame 6.

[0026] like Figures 3 to 5 As shown, a first slider 64 and a second slider 65 are sleeved on the positive and negative threaded screw 62, and the first slider 64 and the second slider 65 are respectively installed on the upper and lower sides of the limit block 63. A slide rail 66 is provided on the left side of the flip frame 6, and the first slider 64 and the second slider 65 are slidably installed on the slide rail 66. The positive and negative threaded screw 62 is a special threaded screw, which is characterized in that it has both positive and negative threads on one screw rod. The two sliders can move synchronously to perform a clamping action under the action of the positive and negative threaded screw 62. A clamping claw body 7 is installed on the first slider 64 and the second slider 65. The clamping claw body 7 includes a first clamping claw 71 and a second clamping claw 72. The first clamping claw 71 and the second clamping claw 72 are both slidably installed on the slide rail 66, and the two sliders move toward each other on the positive and negative threaded screw 62, driving the two clamping claws to clamp the goods.

[0027] When Example 1 is working, the roller conveyor belt and the barcode identifier 4 are started, and the goods with barcodes are placed on the roller conveyor belt. After the goods are transported to the identification area, the barcode identifier 4 on the gantry identifies the barcodes on the top and rear sides of the goods. If the barcode is recognized, the goods continue to be transported. If the barcode is not recognized, the distance adjustment motor 67 is started to drive the forward and reverse screw rods 62 to rotate so that the first slider 64 and the second slider 65 move toward each other, and the first clamping claw 71 and the second clamping claw 72 clamp the goods and fix them. The electric lifting cylinder 51 is started to lift the lifting frame 5, thereby lifting the goods, and the second clamping claw 72 is disengaged from the notch of the roller conveyor belt to ensure rotation. The clamping claws will not collide with the roller during rotation, and the flipping motor 61 is started to rotate the flipping frame 180°, thereby turning the goods over. The electric lifting cylinder 51 is started again to lower the lifting frame 5, and the distance adjustment motor 67 is started to drive the forward and reverse screw rods 62 to rotate so that the first slider 64 and the second slider 65 move in opposite directions. The first clamping claws 71 and the second clamping claws 72 release the goods, and the barcode identifier 4 on the gantry performs barcode recognition on the side of the goods that has not been scanned, thereby performing barcode recognition on all sides of the goods, avoiding the problem of being unable to recognize the barcode when the barcode is located on the bottom surface of the goods, and no manual adjustment is required, which greatly improves the intelligence of barcode recognition. Example 2

[0028] Example 2 is based on Example 1, as Figure 4 and Figure 5 As shown, the upper end surface of the first clamping claw 71 and the lower end surface of the first slider 64 are jointly fixedly installed with an electric clamping cylinder 73, and the lower end surface of the second clamping claw 72 and the upper end surface of the second slider 65 are jointly fixedly installed with an electric clamping cylinder 73. The distance between the two sliders is adjusted by the positive and negative threaded rods 62 to control the distance between the two clamping claws. When performing specific clamping, the electric clamping cylinder 73 controls the two clamping claws to perform a short distance movement to realize the clamping action, which can adapt to clamping goods of different sizes while reducing the time required for the clamping action and improving the clamping efficiency.

[0029] When Example 2 is working, the distance between the two clamping claws is adjusted according to the size of the goods by first starting the distance adjustment motor 67 to drive the forward and reverse screw rods 62 to rotate. When the goods are not recognized after the first scan, the electric clamping cylinder 73 is started to control the first clamping claw 71 and the second clamping claw 72 to clamp the goods, and then perform the flipping action. After the clamping claw distance is pre-adjusted, the clamping action is controlled by the electric cylinder. While adapting to different goods sizes, the moving distance of the clamping claws is reduced, the clamping time is saved, the flipping efficiency is improved, and the efficiency of barcode recognition is also improved.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
