Description

Technical Field

[0001] The present invention relates to the field of code engraving and scanning equipment, and in particular to a laser code engraving and scanning equipment. Background Art

[0002] In modern industrial production, after qualified products are manufactured, they must be coded and scanned to facilitate packaging and storage. Furthermore, this process is essential for ensuring quality control and traceability throughout production and logistics. Furthermore, with the advancement and development of technology, laser code engraving and scanning equipment has become the mainstream tool for product code engraving and scanning.

[0003] In the existing technology, the process of laser code engraving and scanning uses semi-automatic equipment for engraving and scanning, which is highly dependent on manual labor, has low production efficiency and high production costs. In addition, the product is not clamped in the equipment during engraving, which easily leads to poor engraving quality. In addition, the laser equipment uses a high-temperature laser beam to engrave the product surface during engraving, and the focus point of the laser beam will generate strong high temperature. If the worker accidentally touches the laser beam during the operation, it may cause skin burns. At the same time, the focus point of the laser beam will generate strong light, which may damage the scanner gun in serious cases. The laser engraving machine will generate odorous exhaust gas when engraving the product. If the exhaust gas is discharged into the air without treatment, it will cause environmental pollution. Therefore, there is a need for a laser code engraving and scanning device that can solve the above problems. Summary of the Invention

[0069] The four corners of the sliding plate 55 are fixed on four movable bearings;

[0075] In an embodiment of the present invention, Figure 6b As shown, the scanning hole 39 of the semi-sealed box 3 is fixed with:

[0076] L-shaped plate 35 with induction block 36;

[0081] In an embodiment of the present invention, Figure 7 As shown, the slide rail assembly includes:

[0082] Double slide rails 46 and two support legs 45 fixed to the support panel;

[0083] A mounting support 41 fixed on the double slide rails;

[0084] A code engraving machine 4 fixed on the mounting support 41;

[0085] A lead screw 43 having two ends passing through the two support legs 45 and fixed thereto, and a secondary hand wheel 42 mounted on one end;

[0087] The barcode scanner 47 is installed on the support panel through a barcode scanner adjustment seat.

[0088] The working principle of the laser code engraving and scanning device in the embodiment of the present invention is:

[0089] The rotary cylinder drives the turntable to rotate. When the product positioning seat rotates with the turntable to the safety light curtain, the operator or other automated equipment places the corresponding product to be coded in the product positioning seat, or replaces the product positioning seat and places the corresponding product to be coded. The four first proximity switches respectively calculate the distance to the corresponding position in the product positioning seat and compare it with the preset value. If it is greater than the preset value, the green light of the first proximity switch will light up and output a signal that there is a detection hole at that position. Otherwise, the first proximity switch light will not light up and output a signal that there is no detection hole at that position.

[0090] When the product positioning seat rotates to the opening side of the semi-sealed box along with the turntable, the sliding plate in the movable sealing baffle assembly blocks the opening on the opening side, the limit switch is activated and outputs a signal; the cylinder pushes the L-shaped plate to block the code scanning hole, and the second proximity switch detects the sensing block and the green light turns on and outputs a signal;

[0091] When the control cabinet receives the output signal of the second proximity switch, the output signal of the limit switch, and the output signal of the receiving end of the through-beam sensor, it decodes the output signals of the four first proximity switches. If the decoding result is 1, 1, 1, 1, the code corresponding to the decoding result is selected and sent to the code engraving machine. The code engraving machine moves the engraving hole to engrave the product to be engraved. When the engraving is completed, the barcode scanner is controlled to scan the engraved product.

[0092] The components and their models used in the embodiments of the present invention are shown in Table 1:
