DETAILED DESCRIPTION

[0037] The following is combined with Figures 1-10 This application is described in further detail.

[0038] The embodiment of the present application discloses a laser marking device. Figure 1 , including a body 1, a conveying device 2 installed on the body 1 and used to convey products, a conveying device 3 for receiving products on the conveying device 2, an adjusting device 7 installed on the body 1 and used to adjust the position of the products on the conveying device 2, a progressive device 4 installed on the body 1 and used to receive products on the conveying device 2 3, a grabbing device 8 installed on the body 1 and used to grab the products on the conveying device 2 3 and put them on the progressive device 4, a laser engraving device 5 installed on the body 1, an adsorption device 9 installed on the body 1 and used to absorb debris generated by the engraving process, and a recovery device 6 installed on the body 1 and used to recover the engraved products. In an embodiment of the present application, the conveying device 1 2 extends along the width direction of the body 1, the conveying device 2 3 extends along the length direction of the body 1 and the feed end of the conveying device 2 3 is located at the discharge end of the conveying device 1 2, the progressive device 4 extends along the length direction of the body 1 and is located on the same conveying path as the conveying device 2 3, the feed end of the progressive device 4 is aligned with the discharge end of the conveying device 2 3, and the recovery device 6 is arranged along the width direction of the body 1, and the feed end of the recovery device 6 is located at the discharge end of the progressive device 4.

[0039] Reference Figure 2 and Figure 3The conveying surface of conveyor device 1-2 has a higher level than that of conveyor device 2-3. Conveyor device 1-2 includes a conveyor belt 21 mounted on the machine body 1 and extending along the width direction of the machine body 1, a positioning assembly 22 mounted on the machine body 1 and used to position products on conveyor belt 21, and a detection sensor 23 mounted on conveyor belt 21 and located at the discharge end of conveyor belt 21. In the embodiment of the present application, two groups of detection sensors 23 are provided. The detection sensors 23 include a receiver and a transmitter. The two groups of detection sensors 23 are arranged along the length direction of conveyor belt 21. The detection sensor 23 located at the discharge end of conveyor belt 21 is used to detect whether the product has reached the discharge end of conveyor belt 21, and the detection sensor 23 away from the discharge end of conveyor belt 21 is used to detect whether a product has moved to that position. When there is no product at the discharge end of the conveyor belt 21, neither of the two sets of detection sensors 23 detects the product. At this time, the conveying speed of the conveyor belt 21 can be increased. When the detection sensor 23 located at the discharge end of the conveyor belt 21 detects the product, the speed of the conveyor belt 21 is reduced to facilitate the product to be flipped due to the height difference. The positioning assembly 22 includes a connecting rod located on one side of the length direction of the conveyor belt 21, a positioning frame installed on the machine body 1 and used to position the connecting rod, gears installed at both ends of the connecting rod, racks 1 and 2 arranged along the width direction of the conveyor belt 21 and meshing with the gears, a limit bar 1 is provided on the side of the rack 1 close to the length direction of the conveyor belt, and a limit bar 2 is provided on the other side of the rack 2 close to the length direction of the conveyor belt. A rotating handle for controlling the rotation of the gear is provided on the mounting frame, and the limit bars 1 and 2 are controlled to move closer to or farther away from each other by rotating the gears.

[0040] Reference Figure 3 and Figure 4 The conveyor device 2 (3) includes a conveyor belt 2 (31) installed along the length of the machine body 1 and a detection sensor 2 (32) installed on the machine body 1 and located at the feed end of the conveyor belt 2 (31). The feed end of the conveyor belt 2 (31) is located below the discharge end of the conveyor belt 1 (21). When the product moves to the discharge end of the conveyor belt 1 (21), due to the height difference, the arc-shaped product will flip 90 degrees and fall onto the conveyor belt 2 (31). To improve the stability of product flipping, a guide plate 11 is installed at an angle at the discharge end of the conveyor belt 1 (21) toward the conveyor belt 2 (31). The bottom surface of the guide plate 11 is located above the conveying surface of the conveyor belt 2 (31), so that the guide plate 11 can guide the product to flip onto the conveyor belt 2 (31).

[0041] Reference Figure 4 and Figure 5To improve product turnover stability, the adjustment device 7 includes a control rod 71 mounted on the machine body 1 and along the length of the conveyor belt 31; adjustment gears 72 fixedly mounted at both ends of the control rod 71; a mounting bracket 73 mounted on the machine body 1 and used to position the control rod 71; an adjustment rack 74 mounted on the mounting bracket 73 and meshing with the adjustment gear 72; and an adjustment plate 75 mounted on the end of the adjustment rack 74 near the feed end of the conveyor belt 31. A bearing fixedly mounted on the mounting bracket 73 facilitates the rotation of the control rod 71 and improves the positioning of the control rod 71 by the mounting bracket 73. A control handwheel 14 is fixedly mounted at the end of the control rod 71 to facilitate operator rotation of the control rod 71. Guide plate 11 is located at the discharge end of conveyor belt 1 21 and on one side of the length of conveyor belt 2 31. Adjustment plate 75 is located at the feed end of conveyor belt 2 31 and on the other side of the length of conveyor belt 2 31. After the product is flipped, it is located between guide plate 11 and adjustment plate 75. To improve the stability of product flipping, a positioning baffle 751 is fixedly installed on the end of adjustment plate 75 near guide plate 11. Positioning baffle 751 cooperates with guide plate 11 to improve the stability of product flipping. If the product size changes, the operator turns the control handwheel 14 to adjust the distance between positioning baffle 751 and guide plate 11 according to the product size.

[0042] Reference Figure 5 After the products are sequentially flipped onto conveyor belt 2 31, an interceptor plate 12 is fixedly mounted at the discharge end of conveyor belt 2 31, along with a sensor 13 for detecting product arrival. After the products reach the discharge end of conveyor belt 2 31, interceptor plate 12 intercepts them, preventing them from directly exiting conveyor belt 2 31. When conveyor belt 2 31 is full, sensor 2 32 at the feed end of conveyor belt 2 31 detects the products, at which point conveyor belt 2 31 can slow down or even stop.

[0043] Reference Figure 5 and Figure 6When the product reaches the conveyor belt 2 31, the grabbing device 8 transfers the product on the conveyor belt 2 31 to the progressive device 4. The conveyor belt 2 31 serves to store the product and improve the efficiency of product transfer. The grabbing device 8 includes a fixed seat 1 81 fixedly mounted on the machine body 1, a linear motor 1 82 mounted on the fixed seat 1 81 and extending along the length direction of the conveyor belt 2 31 toward the length direction of the progressive device 4, a linear motor 2 83 mounted on the linear motor 1 82, a limit block 84 mounted on the linear motor 2 83 and used to position the product, and a suction nozzle 85 mounted on the limit block 84 and used to absorb the product. The linear motor 1 82 drives the linear motor 2 83 to move from the discharge end of the conveyor belt 2 31 to the feed end of the progressive device 4. The linear motor 2 83 is used to drive the suction nozzle 85 to move up and down to facilitate the suction nozzle 85 to absorb the product. The limit block 84 is used to position the product. The limit block 84 is provided with a through groove 18 along the height direction for the suction nozzle 85 to pass through. Since the product is arc-shaped, the bottom surface of the limit block 84 in the embodiment of the present application is recessed upward to adapt to the arc surface of the product, thereby improving the positioning effect of the limit block 84 on the product.

[0044] Reference Figure 7 and Figure 8 The product is transferred from the conveyor belt 2 31 to the progressive device 4. The progressive device 4 includes a conveyor belt 3 41 installed on the body 1 and extending along the length direction of the body 1 and an adjustment component 42 installed on the body 1 and used to position the product. The conveyor belt 3 41 is used to transfer the product sucked by the suction nozzle 85, and the adjustment component 42 is used to adjust the position of the product to facilitate the unification of the engraving position of the product. The adjusting assembly 42 includes a mounting base 421 installed on the body 1 and located on one side of the length direction of the conveyor belt three 41, an adjusting cylinder 422 fixedly installed on the mounting base 421 and a control rod 2 423 fixedly installed on the piston end of the adjusting cylinder 422, the control rod 2 423 extends toward the other side of the length direction of the conveyor belt three 41, and an adjusting block 17 is fixedly installed on the end of the control rod 2 423 away from the adjusting cylinder 422, the adjusting block 17 is located on one side of the length direction of the conveyor belt three 41, and the adjusting cylinder 422 is installed on the other side of the length direction of the conveyor belt, and the adjusting cylinder 422 is used to adjust the distance between the adjusting block 17 and the mounting base 421, and the product is placed on the conveyor belt three 41 between the adjusting block 17 and the mounting base 421 by the suction nozzle 85. Because the second control rod 423 is relatively long, in order to improve the stability of the movement of the second control rod 423, a slide rail 15 is fixedly mounted on the mounting seat 421 along the width direction of the third conveyor belt 41. A slider 16 located on the slide rail 15 is fixedly mounted on the second control rod 423. When the adjustment cylinder 422 is activated, it drives the adjustment block 17 toward or away from the mounting seat 421. In order to improve the positioning effect of the adjustment block 17 on the product, the adjustment block 17 extends along the length of the conveyor belt, which facilitates the positioning of the product side wall.

[0045] Reference Figure 5 and Figure 9 In order to improve the uniformity of the product marking position, an in-position sensor 19 located at the processing position of the laser marking device 5 is fixedly installed on the conveyor belt 3 41. When the product reaches the position, the conveyor belt 3 41 stops and the laser marking device 5 processes the product. The laser marking device 5 includes a fixed bracket 51 fixedly mounted on the machine body 1, a laser marking machine 52 mounted on the fixed bracket 51, and a detection scanner 53 mounted on the machine body 1 and located at the discharge end of the conveyor belt 3 41. In the embodiment of the present application, the fixed bracket 51 is tilted toward the conveyor belt 3 41, and the laser marking machine 52 is mounted on the slope surface of the fixed bracket 51, so that the laser marking machine 52 can process the arc-shaped product of the present application. A through hole is opened on the side of the fixed bracket 51 facing the conveyor belt 3 41, and the through hole is used for the processing end of the laser marking machine 52 to pass through and perform marking processing on the product. In order to improve the uniformity of product processing positions, an in-position sensor 19 is installed on the conveyor belt 3 41. When the product moves to this position, the in-position sensor 19 senses it and stops the conveyor belt 3 41 in time to facilitate the laser engraving machine 52 to engrave the product.

[0046] Reference Figure 1 and Figure 3 , when the laser engraving machine 52 processes the product, debris will be generated. At this time, the adsorption device 9 adsorbs the impurities generated by the processing to avoid contaminating the processing area. The adsorption device 9 includes a dust collector 91 installed in the body 1 and a guide cover 92 installed at the adsorption end of the dust collector 91. In the embodiment of the present application, the dust collector 91 uses a vacuum cleaner, and the guide cover 92 is used to adjust the suction position of the vacuum cleaner, so that subsequent staff can adjust the suction range according to the processing position. After the laser engraving process is completed, the conveyor belt three 41 starts to convey the processed product to the discharge end of the conveyor belt three 41. The detection scanner 53 scans and detects the product, mainly to check whether the product QR code can be recognized. The products that can be recognized are good products, and those that cannot be recognized are defective products.

[0047] Reference Figure 8 and Figure 9After product processing and inspection are complete, the positions of good and bad products need to be adjusted. A screening device 10 is installed on the machine body 1 and located at the feed end of the recovery device 6.

The conveyor belt 4 61 is used to transport good products, and the recovery assembly 63 is used to recycle bad products. The feed end of the conveyor belt 4 61 and the feed end of the recovery assembly 63 are both located at the discharge end of the conveyor belt 3 41. When the push assembly 62 pushes the product against the flip assembly 102, the product is located at the feed end of the conveyor belt 4 61. If the product is good, the push assembly 101 does not need to be activated. If the product is defective, the push assembly 101 is activated to push the product to the feed end of the recovery assembly 63. A limit assembly is installed on the machine body 1. The limit assembly has the same structure as the positioning assembly 22 and is used to locate the two sides of the conveyor belt 4 61 along its length, thereby positioning the product on the conveyor belt 4 61.

[0048] Reference Figure 7 and Figure 9 After the product processing is completed, the pushing component 62 pushes the product close to the flipping component 102. The pushing component 62 includes a fixing frame 621 installed on the machine body 1, a pushing cylinder 1 622 installed on the fixing frame 621, and a pushing plate 623 fixedly installed on the piston end of the pushing cylinder 1 622. The piston end of the pushing cylinder 1 622 extends along the width direction of the conveyor belt 3 41, the pushing cylinder 1 622 is started, and the pushing plate 623 pushes the product to move to the flipping component 102. When the product is a good product, the flipping component 102 directly flips the product to the feed end of the conveyor belt 4 61. The flipping assembly 102 includes a second fixing seat 1021 fixedly mounted on the machine body 1, a magnetic control component 1022 mounted on the second fixing seat 1021 and located at the feed end of the recovery device 6, and a control motor 1023 fixedly mounted on the second fixing seat 1021. The output end of the control motor 1023 is connected to the magnetic control component 1022, so that the control motor 1023 can drive the magnetic control component 1022 to rotate. In the embodiment of the present application, the magnetic control component 1022 includes a mounting shell and a plurality of magnets evenly mounted in the mounting shell. The control motor 1023 of the present application is set to rotate ninety degrees. After the magnetic control component 1022 absorbs the product, the control motor 1023 drives the product to flip. After the product is flipped ninety degrees, it is consistent with the initial state of transmission, which is convenient for subsequent products to be stacked together, thereby increasing the amount of material transmitted by the conveyor belt four 61.

[0049] Reference Figure 8 When the product being pushed is defective, the pushing assembly 101 is activated, pushing the product to the position of the magnetic control member 1022 located at the feed end of the recovery assembly 63. The pushing assembly 101 includes a pushing cylinder 2 1011 mounted on the body 1, a connecting rod 1012 fixedly mounted on the piston end of the pushing cylinder 2 1011, and a pushing rod 1013 fixedly mounted on the end of the pushing cylinder 2 1011 in the yard of the connecting rod 1012. The pushing assembly 101 and the recovery device 6 are located on the same side, which facilitates the pushing assembly 101 to push the product to move. The pushing rod 1013 extends along the width direction of the conveyor belt 4 61, facilitating the movement of the product from the position of the magnetic control member 1022 near the feed end of the conveyor belt 4 61 to the position near the feed end of the recovery assembly 63.

[0050] Reference Figure 10 The recovery assembly 63 includes a material plate 631 mounted on the machine body 1 and located on one side of the conveyor belt 4 61 in the longitudinal direction, a handle 632 fixedly mounted on the end of the material plate 631 away from the conveyor belt 3 41, and a positioning member 633 mounted on the machine body 1 and used to position the material plate 631. The machine body 1 is fixedly mounted with a guide rail 20 along the length of the material plate 631, and the material plate 631 is fixedly mounted with a guide block 6311 located on the guide rail 20. In the embodiment of the present application, the positioning member 633 uses a positioning cylinder. A hole is opened at the bottom of the material plate 631 for inserting the end of the positioning cylinder. Positioning is achieved by controlling the extension and contraction of the positioning cylinder. When the material plate 631 needs to move, the positioning cylinder moves downward, allowing the material plate 631 to slide, making it easier for staff to retrieve materials.

[0051] Reference Figure 9 and Figure 10Magnetic control member 1022 flips the product, causing a height difference. Therefore, the conveying surface of conveyor belt 4 61 is higher than that of conveyor belt 3 41. Since magnetic control member 1022 attracts the product through magnetic force, the product cannot escape from magnetic control member 1022 on its own. In this case, a shifting assembly 64 is required to shift the product onto conveyor belt 4 61 or the recovery assembly 63. Shifting assembly 64 includes a positioning seat 641 fixedly mounted on the body 1, a driving member 642 mounted on the positioning seat 641 and located above the recovery device 6, and a shifting plate 643 mounted on the driving member 642. The drive member 642 comprises a drive wheel assembly mounted on and located at both ends of the positioning seat 641, and a motor fixedly mounted on the positioning seat 641 and used to drive the rotation of the drive wheel assembly. The drive wheel assembly comprises a first drive wheel fixed to the output end of the motor, a second drive wheel mounted on the positioning seat 641, and a connecting handle. Both the first and second drive wheels are mounted with a rotating shaft, each equipped with a bearing. The connecting handle has a hole for mounting the bearing, and one end of the connecting handle is fixedly mounted on the upper end of the toggle plate 643. When the motor drives the drive wheel assembly to rotate, the toggle plate 643 rotates and moves downward, toggling a product, and then moves upward to toggle the next product.

[0052] The implementation principle of a laser engraving device in an embodiment of the present application is as follows: the staff places the product on conveyor belt 21. When the product reaches the discharge end of conveyor belt 21, the detection sensor 23 detects the product and slows down the conveying speed of conveyor belt 21, allowing the product to fall smoothly onto conveyor belt 2 31. The guide plate 11 and the positioning baffle 751 flip and position the product. After the product is flipped ninety degrees, the arc surface of the product faces upward, which is convenient for subsequent laser engraving.

[0053] Conveyor belt 2 31 sequentially conveys a number of flipped products to the feed end of conveyor belt 3 41. Products are stored on conveyor belt 2 31 and can be used as a transit station. The grabbing device 8 grabs the product onto conveyor belt 3 41, and the adjusting component 42 adjusts and positions the product adsorbed by the suction nozzle 85 onto conveyor belt 3 41 to unify the engraving processing position of the product. After the product adjustment and positioning is completed, it is conveyed toward the laser engraving machine 52. After the in-position sensor 19 detects the product, conveyor belt 3 41 stops moving, and the laser engraving machine 52 processes the product. The adsorption device 9 simultaneously adsorbs the debris generated by the processing. After the laser engraving is completed, conveyor belt 3 41 conveys the next product. The processed product arrives at the detection scanner 53 for scanning and detection to check whether the engraved QR code or barcode is intact and recognizable.

[0054] Recognizable products are pushed directly by push plate 623 to the location of magnetic control element 1022 near the feed end of conveyor belt 4 61. Control motor 1023 then flips magnetic control element 1022, and paddle plate 643 paddles the products to the feed end of conveyor belt 4 61 for collection. Unrecognizable products are pushed by push rod 1013 to the location of magnetic control element 1022 near material plate 631, where they are flipped to the feed end of material plate 631. Paddle plate 643 paddles the products onto material plate 631, and once material plate 631 is full, they are collected by staff.

[0055] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
