[0041] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0042] See also Figures 1 to 9 As shown, a laser automatic coding device includes a material tray 9, a transmission mechanism 5 and a positioning mechanism 7, wherein the material tray 9 has a material trough 91 for placing products 10, the transmission mechanism 5 has a transmission path extending along a first direction and used to transmit the material tray 9, and the positioning mechanism 7 is arranged on the transmission path of the transmission mechanism 5 to position the material tray 9 after the material tray 9 is transmitted to the corresponding position, thereby facilitating laser coding processing of the products in the material tray 9.

[0043] See also Figures 4 to 9 As shown, the transmission mechanism 5 at least includes a first material transmission component 51, which includes a first material transmission seat 511 and two groups of first conveyor belts 512 arranged on the first material transmission seat 511. The two groups of first conveyor belts 512 are spaced apart in a second direction perpendicular to the first direction, and a material transmission channel capable of moving the material supply tray 9 along the first direction is formed between the first material transmission seat 511 and the two groups of first conveyor belts 512. In the first material transmission component 51, the two groups of first conveyor belts 512 are respectively arranged to rotate and be driven. Specifically, on each side, a motor 513 is arranged on the first material transmission seat 511, and a transmission component 514 is arranged between the output shaft of the motor 513 and the transmission roller of the first conveyor belt 512 on the corresponding side.

[0044] The positioning mechanism 7 includes a limiting seat 72 and a positioning seat 71. The limiting seat 72 is fixedly arranged on the first material transfer seat 511, and at least a part of the limiting seat 72 is blocked above the material transfer channel; the positioning seat 71 can be arranged between the two groups of first conveyor belts 512 in an upward and downward direction, and the positioning seat 71 is provided with an adsorption hole 711, and the adsorption hole 711 has an upward adsorption port. The positioning mechanism 7 also includes a negative pressure device (not shown in the figure), which is connected to the adsorption hole 711.

[0045] When the automatic coding device is working, the material tray 9 containing the product 10 is conveyed along the first direction on the transmission mechanism 5. When it is conveyed to the first material conveying assembly 51, the material tray 9 is supported on the two sets of first conveyor belts 512 and is located in the material conveying channel; when the material tray 9 is conveyed to the top of the positioning mechanism 7, the positioning seat 71 in the positioning mechanism 7 moves upward, and the negative pressure generated at the adsorption hole 711 makes the positioning seat 71 contact the bottom surface of the material tray 9, so that the material tray 9 can be adsorbed and fixed on the positioning seat 71. The positioning seat 71 continues to move upward and moves upward synchronously with the material tray 9, and it is not easy to deviate. After running to a preset height, the upper part of the material tray 9 abuts against the limit seat 72, so that the material tray 9 is clamped and fixed between the positioning seat 71 and the limit seat 72. At this time, the laser coding process can be performed on each product 10 in the material tray 9. After the coding is completed, the positioning seat 71 carries the material tray 9 downward. After the material tray 9 falls on the first conveyor belt 512, the positioning seat 71 continues to move downward so that the material tray 9 is separated from the negative pressure adsorption of the adsorption hole 711. The first conveyor belt 512 rotates and continues to transport the material tray 9 along the first direction.

[0046] Specifically, referring to the drawings, the positioning seat 71 has a supporting surface 713 for supporting the material tray 9, the suction port of the suction hole 711 is connected to the supporting surface 713, and a positioning protrusion 712 is provided on the positioning seat 71. The positioning protrusion 712 extends vertically upward from the supporting surface 713. The positioning protrusion 712 has multiple positioning protrusions 712 arranged at intervals, and the bottom of the material tray 9 is provided with multiple positioning grooves (not shown in the figure), and the multiple positioning grooves correspond to the positions of the multiple positioning protrusions 712. Here, there are two positioning protrusions 712 arranged at intervals, and the two positioning protrusions 712 are arranged at two diagonal corners of the positioning seat 71, and all the suction ports are arranged at intervals from each other and are located between the two positioning protrusions 712. During the upward movement of the positioning seat 71, the two positioning protrusions 712 are first inserted into the positioning grooves at the bottom of the material tray 9 accordingly. Then, as the positioning seat 71 gradually rises, the negative pressure at the suction port gradually acts on the bottom surface of the material tray 9, so that the position of the material tray 9 is accurately supported on the supporting surface 713 of the positioning seat 71, thereby facilitating precise coding processing.

[0047] In the above process, the negative pressure of the adsorption hole 711 can exist continuously without frequent switching. When the tray 9 carrying the product 10 reaches the top of the positioning seat 71, the positioning seat 71 moves upward to cooperate with the tray 9 to position and further adsorb and fix the tray 9, and continues to move upward to cooperate with the limit seat 72 to clamp the tray 9, which can ensure the accurate positioning of the tray 9 and the product 10 inside it, and facilitate laser coding processing. After the processing is completed, the positioning seat 71 moves downward, and after the tray 9 is supported on the first conveyor belt 512, the positioning seat 71 continues to move downward and automatically disengages from the adsorption of the tray 9. This makes the entire operation process very smooth and easy to control, and the processing efficiency and processing accuracy can be greatly improved.

[0048] See also Figures 4 to 9 As shown, the limiting seat 72 is in an inverted "L" shape, which includes a vertical extension portion 721 extending in the up and down directions, and a horizontal extension portion 722 extending from the top of the vertical extension portion 721 toward the material transfer channel. All or part of the horizontal extension portion 722 is located directly above the first conveyor belt 512. When the positioning seat 71 moves upward, the edge of the material tray 9 supported by the first conveyor belt 512 can be limited by the horizontal extension portion 722.

[0049] The positioning mechanism 7 also includes a mounting seat 74 and a lifting cylinder 75. The mounting seat 74 is arranged at intervals below the positioning seat 71. The mounting seat 74 is fixed relative to the first material transfer seat 511. A plurality of guide rods 73 are slidably penetrated on the mounting seat 74. The guide rods 73 extend in the vertical direction and the upper ends of the guide rods 73 are fixed on the positioning seat 71, so that the positioning seat 71 can be stably lifted and lowered in the vertical direction; the lifting cylinder 75 includes a cylinder body and a telescopic rod, and the telescopic rod extends in the vertical direction. The cylinder body is fixed on the mounting seat 74, and the telescopic rod is fixedly connected to the bottom of the positioning seat 71. The negative pressure device specifically includes a negative pressure seat 76 and an air pipe (not shown in the figure), one end of the air pipe is connected to the adsorption hole 711 from the bottom of the positioning seat 71, and the other end of the air pipe is connected to the negative pressure seat 76, the negative pressure seat 76 is fixed on the mounting seat 74, and is used to connect the negative pressure source. The setting of the negative pressure seat 76 can make the negative pressure acting from different adsorption holes 711 more balanced and act on the bottom surface of the material tray 9. At the same time, the lifting cylinder 75 is directly arranged between the positioning seat 71 and the mounting seat 74, so that a certain distance is always maintained between the two, which can accommodate the air pipe and facilitate the connection of various components in the negative pressure device with the positioning seat 71.

[0050] See also Figure 3As shown, the coding device also includes a tray supply mechanism 8 and two groups of transfer mechanisms 6. The tray supply mechanism 8 transmits the tray 9 along the third direction. The tray supply mechanism 8 is arranged below the transmission mechanism 5. The third direction is parallel to the first direction and faces oppositely; the two groups of transfer mechanisms 6 are arranged on different sides of the transmission mechanism 5 and the tray supply mechanism 8. The transfer mechanism 6 has a transfer seat 61 that can be lifted and lowered along the up and down directions, and a transfer transmission component 62 arranged on the transfer seat 61. The transfer seat 61 can be lifted and lowered between a first height position and a second height position. At the first height position, the transfer transmission component 62 is engaged with the transmission mechanism 5 in the first direction, so that the tray 9 is transferred between the two; at the second height position, the transfer transmission component 62 is engaged with the tray supply mechanism 8 in the third direction to transfer the tray 9 between the two. In this way, when the coding device is working, the empty tray 9 first receives the product 10 at the starting end of the transmission mechanism 5; then, the tray 9 is transmitted along the first direction on the transmission mechanism 5, and is positioned at the positioning mechanism 7 to receive the coding process; then, the tray 9 is transmitted along the first direction on the transmission mechanism 5 to its end, and the coded products in the tray 9 are transferred at the end, and the empty tray 9 is transferred to the tray supply mechanism 8 below through a group of transfer mechanisms 6, and is transmitted along the third direction, and then transferred to the upper transmission mechanism 5 by another group of transfer mechanisms 6, so as to realize the automatic circulation of the tray 9.
