[0034] Example 1

[0035] The embodiment of the present invention provides a traceability code laser engraving method, such as Figure 1 As shown, the following steps are included:

[0036] Step 1: Pre-store the traceability code file in the industrial computer of marking device 1;

[0037] Step 2: Carve the traceability code at a predetermined position on the bottle body 2 by using the marking device 1;

[0038] Step 3: Clean the bottle 2 and transfer it to the next process.

[0039] The working principle and beneficial effects of the above technical solution are: first, the traceability code file is pre-stored in the industrial computer of the marking device 1; then, the traceability code is engraved at a predetermined position of the bottle body 2 by the marking device 1, and the material of the bottle body 2 includes but is not limited to transparent glass and transparent plastic material; finally, the bottle body 2 is cleaned and transferred to the next process. In the above solution, the traceability code is engraved at a predetermined position of the bottle body 2 by the marking device 1, so that the traceability code is not easily lost, which facilitates the traceability of the bottle body 2.

[0040] Example 2

[0041] On the basis of the above-mentioned embodiment 1, Figure 2 As shown, the traceability code includes a barcode;

[0042] The traceability code also includes a directional mark, which is set on one side of the barcode, and one end of the directional mark is used to indicate the positive direction of barcode recognition.

[0043] The working principle and beneficial effects of the above technical solution are as follows: the barcode of the traceability code can be in the form of a digital barcode, an alphabetic barcode or a combination of the two, and a directional mark is also set on one side of the barcode. Preferably, the directional mark is above or below the barcode, and the directional mark includes but is not limited to the letter "A". The top tip of "A" indicates the positive direction of the traceability code digital identification, which is convenient for users or collection systems to read the traceability code.

[0044] Example 3

[0045] Based on Example 1 or 2, in step 2, the predetermined position includes but is not limited to the inner wall of the bottle bottom, the bottle bottom interlayer, the outer wall of the bottle bottom, and the bottle wall interlayer;

[0046] After the traceability code is engraved, the debris generated by the engraving is sucked away by the debris removal mechanism 6 .

[0047] The working principle and beneficial effects of the above technical solution are as follows: the marking device 1 can be a laser marking machine or a laser inner engraving machine. When the predetermined position is the inner wall of the bottom of the bottle body 2, the laser marking machine is used to engrave the traceability code in the form of a digital bar on the inner wall of the bottom of the bottle through the bottle mouth, and then the debris generated by the engraving is removed by the chip removal mechanism 6. The chip removal mechanism 6 can be a vacuum cleaner or an air blower. Preferably, the chip removal mechanism uses a vacuum cleaner; when the predetermined position is the interlayer of the bottom of the bottle body 2, the laser inner engraving machine is used to engrave the traceability code in the form of a digital bar on the interlayer of the bottom of the bottle through the bottle mouth. Optimally, the predetermined position is a non-bottle body outer wall position. At this time, the traceability code is located inside the bottle body 2, and the traceability code will not rub against external objects, thereby reducing the wear of the traceability code and facilitating the traceability of the bottle body 2.

[0048] Example 4

[0049] On the basis of any one of Examples 1-3, in step 3, cleaning the bottle body 2 includes cleaning, sterilizing, and cooling the bottle body 2 by a washing and drying machine.

[0050] The working principle and beneficial effects of the above technical solution are as follows: after the traceability code is engraved, the bottle body 2 is cleaned, sterilized and cooled by the integrated washing and drying machine, thereby improving the cleanliness of the bottle body 2 and facilitating the filling of subsequent materials.

[0051] Example 5

[0052] On the basis of any one of Examples 1-4, Figure 3 As shown, the traceability code laser engraving device adopts the above-mentioned traceability code laser engraving method for engraving, including a workbench 3, on which a first rotating conveying mechanism, a second rotating conveying mechanism and a plurality of linear conveying mechanisms 4 are arranged, a feeding mechanism 5 is arranged on one side of the first rotating conveying mechanism, a second rotating conveying mechanism is arranged on the other side of the first rotating conveying mechanism, a marking device 1 is arranged above the first rotating conveying mechanism, and a chip removal mechanism 6 is arranged below the second rotating conveying mechanism;

[0053] The first rotating conveying mechanism includes a driving motor and a first rotating disk 7. The driving motor is arranged on the workbench 3. The output shaft of the driving motor is connected to the center of the first rotating disk 7. A plurality of first placement slots 8 are arranged on the outer periphery of the first rotating disk 7. The plurality of first placement slots 8 are distributed in a ring array.

[0054] A protective plate 9 is arranged outside the first rotating disk 7, the bottom of the protective plate 9 is connected to the workbench 3, the protective plate 9 is in an arc-shaped structure, and a support plate is arranged on the side of the protective plate 9 close to the first rotating disk 7, and the support plate is located below the first rotating disk 7;

[0055] The second rotating conveying mechanism includes a second rotating disk 10, which is driven by a transmission assembly. A plurality of second placement grooves 11 are arranged on the outer periphery of the second rotating disk 10. The plurality of second placement grooves 11 are distributed in a circular array. An anti-drop assembly is arranged in the second placement groove 11, and the anti-drop assembly is used to prevent the bottle body 2 from falling from the second placement groove 11.

[0056] The working principle and beneficial effects of the above technical solution are as follows: the bottle body 2 is transported to the first rotating conveying mechanism through the loading mechanism 5, and the loading mechanism 5 is an existing automatic bottle row mechanism, which is convenient for the automatic loading of the bottle body 2, and then the single bottle body 2 enters the first placement slot 8 of the first rotating disk 7 with the bottle mouth facing upward, and the driving motor is started, and the driving motor drives the first rotating disk 7 to rotate, and the bottle body 2 slides along the upper surface of the support plate, and the protective plate 9 is provided, so that the bottle body 2 can be stably maintained in the first placement slot 8, and when the bottle body 2 moves below the marking device 1, the driving motor stops rotating, and the marking device 1 emits a laser and engraves a traceability code at a predetermined position on the bottom of the bottle. After the traceability code is engraved, the marking device 1 is turned off, and the driving motor is started again and drives the first rotating disk 7 to rotate, and a linear conveying mechanism 4 is provided between the first rotating conveying mechanism and the second rotating conveying mechanism. Preferably, the linear conveying mechanism 4 is a mechanical rocker arm. When the first placement slot 8 and the second placement slot 8 are aligned, the linear conveying mechanism 4 is rotated. When the placement slots 11 are connected and aligned, the bottle body 2 located in the first placement slot 8 enters the second placement slot 11 under the conveyance of the linear conveying mechanism 4, and then the second rotating disk 10 rotates with the first rotating disk 7 under the drive of the transmission component. When the bottle body 2 in the second placement slot 11 reaches above the chip removing mechanism 6, the chip removing mechanism 6 is started, thereby sucking out the debris generated by the carving inside the bottle body 2, improving the cleanliness inside the bottle body 2, and ensuring the quality and safety of the product filled in the bottle body 2. After the debris is sucked out, the second rotating disk 10 rotates to make the bottle body 2 away from the chip removing mechanism 6. When the bottle body 2 reaches another linear conveying mechanism 4, the linear conveying mechanism 4 can convey the bottle body 2 with the debris removed to the next process. An anti-drop component is arranged in the second placement slot 11. When the second rotating disk 10 rotates, the anti-drop component can prevent the bottle body 2 from falling from the second placement slot 11, thereby improving the reliability of the rotation and conveying of the bottle body 2.

[0057] Example 6

[0058] Based on Example 5, the transmission assembly includes a first sprocket arranged on the output shaft of the driving motor, a rotating shaft arranged at the bottom center of the second rotating disk 10, a second sprocket arranged on the rotating shaft, and the first sprocket and the second sprocket are connected by a chain transmission.

[0059] The working principle and beneficial effects of the above technical solution are as follows: when the driving motor rotates, the output shaft of the driving motor drives the first sprocket to rotate, and the rotation of the first sprocket drives the second sprocket to rotate through the chain, thereby driving the rotating shaft to rotate. The rotation of the rotating shaft can drive the second rotating disk 10 to rotate synchronously with the first rotating disk 7, thereby improving the consistency of rotation of the first rotating disk 7 and the second rotating disk 10. The number of first placement slots 8 is the same as the number of second placement slots 11, and initially, one of the first placement slots 8 of the first rotating disk 7 is connected to one of the second placement slots 11 of the second rotating disk 10. When the marking equipment 1 engraves the traceability code through the bottle mouth, the chip removal mechanism 6 works synchronously to absorb chips from the corresponding bottle body 2, thereby improving production efficiency.

[0060] Example 7

[0061] On the basis of Example 5 or 6, Figure 4-Figure 8 As shown, the anti-drop assembly includes rotating holes 12 symmetrically arranged on both sides of the second placement groove 11, a driving hole 13 is arranged at one end of the rotating hole 12 away from the second placement groove 11, the driving hole 13 is perpendicular to the rotating hole 12, the rotating hole 12 and the driving hole 13 are both arranged in the second rotating disk 10, the driving hole 13 passes through the bottom wall of the second rotating disk 10 near the end of the workbench 3, a driving block 14 is slidably arranged in the driving hole 13, the driving block 14 is hemispherical at one end near the workbench 3, a sliding block 15 is arranged at the side of the driving block 14 away from the rotating hole 12, the sliding block 15 is slidably arranged in a slide groove 16, the slide groove 16 is arranged in the second rotating disk 10, the sliding block 15 is connected to the inner wall of the slide groove 16 through a connecting spring, a guide groove 17 is arranged at one side of the driving block 14 near the rotating hole 12, a guiding inclined surface is arranged on the inner wall of the guide groove 17, and the guide groove 17 is near the workbench 3. The end depth is greater than the depth of the end of the guide groove 17 away from the workbench 3. A rotating shaft 18 is rotatably set in the rotating hole 12. One end of the rotating shaft 18 extends into the second placement groove 11 and is connected to the stopper 19. The stopper 19 is set in the second placement groove 11. One side of the stopper 19 is adapted to the outer wall of the bottle body 2. A first sliding hole and a second sliding hole are set in the rotating shaft 18. The second sliding hole is located at an end of the first sliding hole close to the second placement groove 11. The second sliding hole is connected to the second placement groove 11. A sliding column 20 is slidably set in the first sliding hole. One end of the sliding column 20 extends into the guide groove 17 and is provided with a ball 21. The other end of the sliding column 20 extends into the second sliding hole and is provided with a clamping block 22. The clamping block 22 is slidably connected to the inner wall of the second sliding hole. A reset spring 23 is set in the second sliding hole, and the clamping block 22 is connected to the inner wall of the second sliding hole through the reset spring 23.

[0062] The working principle and beneficial effects of the above technical solution are as follows: when the first placement groove 8 is connected to the second placement groove 11, the bottle body 2 in the first placement groove 8 can be transferred to the second placement groove 11 through the linear conveying mechanism 4, and the linear conveying mechanism includes a transmission chain plate. Under the transmission of the linear conveying mechanism, the bottle body 2 can contact the stopper 19, and there is a gap between the stopper 19 and the innermost part of the second placement groove 11. Then, as the second rotating disk 10 rotates, the lower end of the driving block 14 slides along the upper surface of the transmission chain plate. When the driving block 14 is separated from the transmission chain plate, Under the action of gravity and the connecting spring, the driving block 14 slides downward in the driving hole 13, and the slider 15 slides downward in the slide groove 16. Since the ball 21 contacts the guiding inclined surface, when the driving block 14 drives the guiding groove 17 to move downward, the guiding inclined surface can push the sliding column 20 to slide along the first sliding hole toward the bottle body 2, and then drives the clamping block 22 to move toward the bottle body 2 until the clamping block 22 is in close contact with the outer wall of the bottle body 2. When the bottle body 2 is separated from the transmission chain plate, the bottle body 2 is in a suspended state at the bottom, and the clamping block 22 is used to clamp the bottle body 2. The clamping of the outer wall of the bottle body 2 can prevent the bottle body 2 from falling during the rotating conveying process, thereby improving the stability and reliability of the bottle body 2 during the conveying process. When the other driving block 14 is separated from the transmission chain plate, the other clamping block 22 also clamps the outer wall of the bottle body 2, so that the bottle body 2 is in the middle position of the second placement groove 11, which facilitates the input end of the chip removal mechanism 6 to align with the bottle mouth of the bottle body 2, thereby ensuring the chip suction ability of the chip removal mechanism 6, enhancing the chip suction effect, making the debris inside the bottle body 2 more thoroughly removed, and improving the cleanliness inside the bottle body 2; the chip removal mechanism After the chips are sucked, the clean bottle body 2 is rotated and transported to another linear conveying mechanism 4. Since the bottom of the driving block 14 is hemispherical, when the side wall of the driving block 14 contacts the transmission chain plate, the driving block 14 can slide into the driving hole 13, and the bottom of the driving block 14 slides back onto the transmission chain plate. When the driving blocks 14 on both sides of the second placement groove 11 contact the transmission chain plate of the linear conveying mechanism 4, the two clamping blocks 22 are separated from the outer wall of the bottle body 2. At this time, under the transmission of the linear conveying mechanism 4, the bottle body 2 can smoothly enter the next process.

[0063] Example 8

[0064] On the basis of Example 7, Figure 3 , Figure 4 , Figure 6As shown, it also includes a rotating component, which includes a third sliding hole. The third sliding hole is arranged in the second rotating disk 10, the third sliding hole is perpendicular to the rotating hole 12, and the third sliding hole is connected with the rotating hole 12 near the middle position. A gear 24 is arranged at the intersection of the third sliding hole and the rotating hole 12, and the gear 24 is installed on the rotating shaft 18. One end of the third sliding hole passes through the outer wall of the second rotating disk 10, a mounting plate 25 is arranged on the workbench 3, and an electric push rod 26 is arranged on the mounting plate 25. A rack 27 is arranged at the output end of the electric push rod 26, and the rack 27 is aligned with the entrance of the third sliding hole at one end away from the electric push rod 26.

[0065] The working principle and beneficial effects of the above technical solution are as follows: when the bottle body 2 reaches the top of the chip removal mechanism 6, the electric push rod 26 is started, the electric push rod 26 is pushed out and drives the rack 27 to move toward the third sliding hole, and the rack 27 enters the third sliding hole and moves along the inner wall of the third sliding hole. When the rack 27 is meshed with the gear 24, the rack 27 continues to move to drive the gear 24 to rotate. The rotation of the gear 24 drives the rotating shaft 18 to rotate in the rotating hole 12. The rotation of the rotating shaft 18 drives the clamping block 22 and the stopper 19 to rotate in the second placement groove 11, thereby driving the bottle body 2 to rotate from the bottle mouth upward to the bottle mouth downward. The debris on the inner wall of the bottle body 2 falls toward the chip removal mechanism 6 under the action of gravity. At the same time, the chip removal mechanism 6 is started to absorb the fallen debris to prevent the debris from remaining in the bottle body 2. After the absorption is completed, the electric push rod 26 returns to its original position, and the bottle body 2 is rotated again from the bottle mouth downward to the bottle mouth upward, which is convenient for subsequent transmission and filling. Through the above scheme, the bottle body 2 can be rotated in the second placement groove 11 to the bottle mouth facing downward, which is convenient for the removal of debris and prevents larger particles of debris from being sucked out, further improving the cleanliness of the inside of the bottle body 2 and making the traceability code clearer.
