Description

Technical Field

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

[0002] In the manufacturing industry, laser engraving QR codes on the surface of products and marking product information by scanning the code for the first time can improve the efficiency and accuracy of the production line, help companies track the entire process of product production, circulation and sales, improve management efficiency and reduce costs. At the same time, laser engraved QR codes have high anti-counterfeiting properties and are difficult to forge and imitate, effectively preventing the emergence of counterfeit and shoddy products.

[0003] The existing laser engraving equipment mainly includes a loading robot, a unloading robot, a conveyor line and a laser engraving machine. The laser engraving machine is set on one side of the conveyor line. When working, the loading robot transfers the product to the conveyor line, and then the conveyor line conveys the product along the preset direction. When the product is conveyed to one side of the laser engraving machine, the laser engraving machine laser engraves the QR code on the product. When the product is laser engraved, it is further conveyed forward by the conveyor line, and finally the unloading robot removes the product from the conveyor line. In order to improve the efficiency of laser engraving, the current method mainly increases the number of laser engraving machines along the preset direction, so as to perform batch laser engraving on the products on the conveyor line.

[0004] In actual application, the size of some products in the preset direction is much smaller than that of the laser engraving machine in the preset direction, and space for installation and maintenance needs to be reserved between two adjacent laser engraving machines, resulting in a large distance between two adjacent products on the conveyor line. Therefore, it is necessary to reserve sufficient length at both the head and tail ends of the conveyor line to free up enough space for loading and unloading, resulting in a longer conveyor line, occupying too much space, and causing an increase in production costs; in addition, in order to achieve batch loading and unloading of multiple products with large spacing, it is necessary to equip multiple loading and unloading manipulators to work simultaneously, or to equip both the loading and unloading manipulators with longer clamps, which in turn exacerbates the increase in production costs. Summary of the invention

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0044] Refer to the following Figures 1 to 6 The laser engraving and scanning device provided by the present invention is described.

[0045] Reference Figure 1The laser engraving and code scanning equipment of the product comprises a base 8, a conveyor line 1, a laser engraving mechanism 3 and a code scanner 4. The conveyor line 1, the laser engraving mechanism 3 and the code scanner 4 are all arranged on the base 8. The conveyor line 1 can convey the product 100 along the first direction. One end of the conveyor line 1 is a loading end, and the other end is a unloading end. The laser engraving mechanism 3 is arranged on the side of the conveyor line 1, and the laser engraving mechanism 3 can laser engrave the product 100 conveyed to one side of the conveyor line 1; the code scanner 4 is arranged on one side of the conveyor line 1, and the code scanner 4 can scan the product 100 laser engraved by the laser engraving mechanism 3.

[0046] Reference Figure 2 and Figure 3 Furthermore, a plurality of carriers 2 are arranged on the conveyor line 1, and each carrier 2 is provided with N loading positions 21 in sequence from the loading end to the unloading end, where N is greater than or equal to 2, and each loading position 21 can position a product 100. N laser engraving mechanisms 3 are arranged in sequence along the first direction on one side of the conveyor line 1, and the N laser engraving mechanisms 3 are arranged in sequence corresponding to the N loading positions 21, and each laser engraving mechanism 3 docks with one carrier 2 at a time and performs laser engraving on the product 100 at the corresponding loading position 21. Specifically, the loading position 21 closest to the loading end is the first loading position 21, and the loading position 21 farthest from the loading end is the Nth loading position 21; the laser engraving mechanism 3 closest to the loading end is the first laser engraving mechanism 3, and the laser engraving mechanism 3 farthest from the loading end is the Nth laser engraving mechanism 3. The first laser engraving mechanism 3 is configured to sequentially laser engrave the products 100 positioned at the first loading position 21 in all the carriers 2, and the Nth laser engraving mechanism 3 is configured to sequentially laser engrave the products 100 positioned at the Nth loading position 21 in all the carriers 2.

[0047] It should be noted that in some other embodiments, the N laser engraving mechanisms 3 may be distributed on both sides of the conveyor line 1 , that is, not all of the N laser engraving mechanisms 3 are located on one side of the conveyor line 1 , and the specific distribution method can be adjusted as needed.

[0048] Preferably, in this embodiment, N is equal to 4 as an example, that is, four loading positions 21 are sequentially arranged on each carrier 2, and four laser engraving mechanisms 3 are sequentially arranged on one side of the conveyor line 1. Optionally, in some other embodiments, N may also be equal to other values ​​such as 2, 3, 5 or 6.

[0049] When the product laser engraving and scanning device starts working, after the first carrier 2 with four loading positions 21 is loaded with four products 100, it is first transported to the position of docking with the first laser engraving mechanism 3 through the conveyor line 1. At this time, the first laser engraving mechanism 3 performs laser engraving on the product 100 at the first loading position 21 on the first carrier 2. Then, the conveyor line 1 transports the first carrier 2 to the position of docking with the second laser engraving mechanism 3, and the second carrier 2 located upstream of the first carrier 2 is docked with the first laser engraving mechanism 3. At this time, the second laser engraving mechanism 3 performs laser engraving on the product 100 at the second loading position 21 on the first carrier 2, and the first laser engraving mechanism 3 performs laser engraving on the product 100 at the first loading position 21 on the second carrier 2.

[0050] Then, the conveyor line 1 conveys the first carrier 2 to the position where it docks with the third laser engraving mechanism 3, and the second carrier 2 located upstream of the first carrier 2 docks with the second laser engraving mechanism 3, and the third carrier 2 located upstream of the second carrier 2 docks with the first laser engraving mechanism 3. At this time, the third laser engraving mechanism 3 performs laser engraving on the product 100 in the third loading position 21 on the first carrier 2, and the second laser engraving mechanism 3 performs laser engraving on the product 100 in the second loading position 21 on the second carrier 2, and the first laser engraving mechanism 3 performs laser engraving on the product 100 in the first loading position 21 on the third carrier 2.

[0051] By analogy, when the conveyor line 1 conveys the first carrier 2 to the position where it docks with the fourth laser engraving mechanism 3, the second carrier 2 located upstream of the first carrier 2 docks with the third laser engraving mechanism 3, the third carrier 2 located upstream of the second carrier 2 docks with the second laser engraving mechanism 3, and the fourth carrier 2 located upstream of the third carrier 2 docks with the first laser engraving mechanism 3. At this time, the fourth laser engraving mechanism 3 performs laser engraving on the product 100 in the fourth loading position 21 on the first carrier 2, while the third laser engraving mechanism 3 performs laser engraving on the product 100 in the third loading position 21 on the second carrier 2, the second laser engraving mechanism 3 performs laser engraving on the product 100 in the second loading position 21 on the third carrier 2, and the first laser engraving mechanism 3 performs laser engraving on the product 100 in the first loading position 21 on the fourth carrier 2.

[0052] At this point, all products 100 on the first carrier 2 have been laser engraved, and the product laser engraving and barcode scanning equipment has officially entered assembly line operation. When the conveyor line 1 continues to convey the carrier 2, the products 100 on the subsequent carriers 2 are laser engraved in turn according to the above sequence, and each time the conveyor line 1 conveys forward, the conveying stroke is the length of a single carrier 2 in the first direction, and the four laser engraving mechanisms 3 all work synchronously, so as to perform batch laser engraving on the products 100.

[0053] Based on the above content, in the present invention, four laser engraving mechanisms 3 are used to laser engrave the products 100 on each carrier 2 one by one in four times, and each laser engraving mechanism 3 only docks with one carrier 2 each time, so that the size of each carrier 2 along the first direction is close to the size of each laser engraving mechanism 3 along the first direction, that is, only one space required for a laser engraving mechanism 3 in the first direction needs to be reserved at the loading and unloading ends of the conveyor line 1. Compared with the existing arrangement, the loading and unloading ends of the conveyor line 1 need to reserve the space required for four laser engraving mechanisms 3 in the first direction, so the length required to be reserved at the loading and unloading ends of the conveyor line 1 is greatly shortened, thereby shortening the overall length of the conveyor line 1, which not only saves the space required for the product laser engraving scanning equipment, but also reduces the cost of the conveyor line 1.

[0054] Reference Figure 2 Furthermore, N scanners 4 are sequentially arranged along the first direction on one side of the conveyor line 1. Specifically, the scanner 4 closest to the loading end is the first scanner 4, and the scanner 4 farthest from the loading end is the Nth scanner 4. The first scanner 4 is configured to sequentially scan the products 100 located at the first loading position 21 in all carriers 2, and the Nth scanner 4 is configured to sequentially scan the products 100 located at the Nth loading position 21 in all carriers 2. The scanner 4 is used to scan the laser-engraved products 100, and the information of the products 100 that have been successfully scanned is entered, and the products 100 that have failed to be scanned are marked so that they can be laser-engraved again later or directly scrapped, so that the scanner 4 is integrated on the base 8, making the equipment more integrated. Since the number of barcode scanners 4 is consistent with the number of laser engraving mechanisms 3, that is, four barcode scanners 4 are also provided in this embodiment, the products 100 can be batch scanned with reference to the operation mode of the four laser engraving mechanisms 3, that is, the four barcode scanners 4 scan one of the products 100 on the four carriers 2 at a time.

[0055] In order to make the laser engraving and scanning device of the product more compact, in this embodiment, four scanners 4 and four laser engraving mechanisms 3 are arranged at intervals, that is, a single scanner 4 is arranged between two adjacent laser engraving mechanisms 3, so that the space required by the four scanners 4 in the first direction can be greatly reduced. In addition, since it takes a while for the product 100 to be scanned after laser engraving, the first scanner 4 in this embodiment is located between the second laser engraving mechanism 3 and the third laser engraving mechanism 3, and so on, the second scanner 4 is located between the third laser engraving mechanism 3 and the fourth laser engraving mechanism 3, the third scanner 4 is located downstream of the fourth laser engraving mechanism 3, and the fourth scanner 4 is located downstream of the third scanner 4.

[0056] The above-mentioned arrangement of the barcode scanner 4 using the gap between two adjacent laser engraving mechanisms 3 greatly shortens the space required for the four barcode scanners 4 in the first direction, compared with arranging all four barcode scanners 4 downstream of the fourth laser engraving mechanism 3 and spacing them apart from the fourth laser engraving mechanism 3. This can further shorten the size of the product's laser engraving and scanning device in the first direction.

[0057] It should be noted that the base 8 in this embodiment is horizontally arranged, and the first direction is the horizontal direction, and the specific structures of the conveyor line 1, the laser engraving mechanism 3 and the barcode scanner 4 are described in this orientation in the following content of this embodiment.

[0058] Reference Figure 2 and Figure 3 For example, the conveyor line 1 in this embodiment is a chain plate conveying mechanism, and the carrier 2 is positioned on the chain plate of the chain plate conveying mechanism. A plurality of carriers 2 are arranged on the outer ring of the chain plate, and all carriers 2 circulate. A plurality of positioning grooves 22 are provided along the length direction of each carrier 2 on the surface away from the chain plate. The positioning grooves 22 are arranged in a square shape. Four positioning grooves 22 are used as an example in this embodiment. Each positioning groove 22 forms a loading position 21 for positioning the product 100, so that four loading positions 21 are formed on each carrier 2.

[0059] Furthermore, in this embodiment, the depth of the positioning groove 22 is equal to the thickness of the product 100, that is, the product 100 can be fully embedded in the positioning groove 22, and a plurality of receiving grooves 23 connected to the positioning groove 22 are also provided on the circumferential side wall of each positioning groove 22. In this embodiment, four receiving grooves are taken as an example, that is, one receiving groove 23 is provided corresponding to each side of the product 100.

[0060] The positioning groove 22 that can be fully embedded in the product 100 can improve the positioning effect of the product 100 and protect the product 100. The receiving groove 23 is convenient for the clamp to extend into the receiving groove 23 to grab the product 100. The position to be laser engraved on the product 100 can also be exposed through the receiving groove 23, so that the scanner 4 can directly scan the product 100 in the loading position 21. Optionally, in some other embodiments, the position to be laser engraved on the product 100 can also be exposed by reducing the depth of the positioning groove 22.

[0061] Reference Figure 4, each laser engraving mechanism 3 includes a sliding frame 31 and a laser head 32. The sliding frame 31 can slide in a direction perpendicular to the first direction. Specifically, a screw module 33 is connected to the bottom of each sliding frame 31 on the base 8. The sliding frame 31 is vertically arranged, and the bottom of the sliding frame 31 is connected to the screw module 33. The driving direction of the screw module 33 is horizontal and perpendicular to the first direction. In some other embodiments, the sliding frame 31 can also be driven to slide by an oil cylinder or an air cylinder. The laser head 32 is connected to the side of the sliding frame 31 close to the conveyor line 1. The laser head 32 can perform laser engraving on the product 100, and the emission end of the laser head 32 faces the conveyor line 1.

[0062] Reference Figure 1 and Figure 5 In addition, in order to prevent the laser head 32 from easily ablating the carrier 2 and other products 100 when working, the product laser engraving and scanning equipment also includes a removal mechanism 5, and a material moving bracket 81 is arranged on the base 8, and the material moving bracket 81 is located on the side of the conveyor line 1 away from the laser engraving mechanism 3. The removal mechanism 5 is arranged on the material moving bracket 81 corresponding to each laser engraving mechanism 3, and the removal mechanism 5 is configured to move the product 100 out of the carrier 21 and align the part to be laser engraved on the product 100 with the laser head 32.

[0063] Specifically, the removing mechanism 5 includes a material moving seat 51 and a material moving clamp 52. The material moving seat 51 is connected to the material moving bracket 81. The material moving clamp 52 is slidably connected to the side of the material moving seat 51 close to the laser head 32. The sliding direction of the material moving clamp 52 is perpendicular to the sliding direction of the sliding frame 31 and the first direction. In this embodiment, the material moving clamp 52 slides in the vertical direction, and the sliding of the material moving clamp 52 is driven by a cylinder; in some other implementations, the sliding of the material moving clamp 52 can also be driven by an electric cylinder or an oil cylinder.

[0064] Furthermore, the material moving clamp 52 has a plurality of claws 521 that can move closer to or farther from each other, and the plurality of claws 521 can be inserted into the receiving groove 23 and abut against the side wall of the product 100. The material moving clamp 52 of this embodiment is a pneumatic clamp, which is connected to the piston rod of the cylinder and has four claws 521, that is, one claw 521 is provided for each receiving groove 23.

[0065] Based on the above, taking the working process of the first laser engraving mechanism 3 as an example, when the product 100 at the first loading position 21 on the carrier 2 reaches one side of the laser engraving mechanism 3, the material moving clamp 52 is first driven downward by the cylinder to make the claw 521 of the material moving clamp 52 extend into the receiving groove 23 and clamp the product 100, and then the material moving clamp 52 is moved upward until the position to be laser engraved on the product 100 is aligned with the laser head 32. At this time, the product 100 is laser engraved by the laser head 32, and then the removal mechanism 5 puts the product 100 back to the first loading position 21. While clamping the product 100, the material moving clamp 52 also has the effect of accurately positioning the product 100, that is, the four claws 521 respectively abut the four side walls of the product 100, so that the product 100 is accurately positioned.

[0066] In addition, each material moving seat 51 is also covered with a fume hood 53 on its exterior. The fume hood 53 is connected to the material moving seat 51 and is connected to the smoke duct of the factory through a pipeline to exhaust the smoke generated during the laser engraving operation.

[0067] Exemplarily, the barcode scanner 4 is connected to the base 8 via a barcode scanner bracket 41. The barcode scanner 4 is any barcode scanner 4 in the prior art that can scan a QR code, and the specific structure is not limited. The barcode scanner 4 is electrically connected to the control system of the laser engraving and scanning device of the product.

[0068] Reference Figure 1 and Figure 6 In order to facilitate loading and unloading of the conveyor line 1, the product laser engraving and scanning device further includes a loading mechanism 6 and a unloading mechanism 7. The loading mechanism 6 is configured to transfer multiple products 100 to be laser engraved to the carrier 2. The number of products 100 transferred by the loading mechanism 6 at a time is consistent with the number of loading positions 21 on a single carrier 2, that is, the loading mechanism 6 transfers four products 100 at a time. The unloading mechanism 7 is configured to move multiple products 100 after laser engraving out of the carrier 2. The number of products 100 transferred by the unloading mechanism 7 at a time is consistent with the number of loading positions 21 on a single carrier 2, that is, the unloading mechanism 7 transfers four products 100 at a time.

[0069] Specifically, the feeding mechanism 6 includes a driving member 61, a fixture plate 62, a transfer member 63 and a defective transfer member 64. The driving member 61 can drive the fixture plate 62 to move. The fixture plate 62 is rotatably connected to the driving member 61. The driving member 61 in this embodiment is a manipulator, and the rotation axis of the fixture plate 62 is perpendicular to the surface of the fixture plate 62. There are multiple transfer members 63 connected to the fixture plate 62. In this embodiment, four are taken as an example. The four transfer members 63 are arranged along the length direction of the fixture plate 62, that is, the arrangement direction of the four transfer members 63 is perpendicular to the rotation axis of the fixture plate 62. The transfer member 63 in this embodiment is a pneumatic clamp. In some other embodiments, the transfer member 63 can also be a suction nozzle or an electromagnet.

[0070] Furthermore, the defective product transfer piece 64 is connected to the fixture plate 62 or the transfer piece 63, and the defective product transfer piece 64 can pick up unqualified products 100. In this embodiment, the defective product transfer piece 64 is also a pneumatic clamp and is connected to one of the transfer pieces 63; in some other embodiments, the transfer piece 63 may also be a suction nozzle or an electromagnet.

[0071] In addition, a drawer 83 is slidably connected to the base 8 near the loading end, and a material tray 82 is placed inside the drawer 83. When the loading mechanism 6 is working, the defective product transfer member 64 first clamps the defective products of the previous station, and drives the defective product transfer member 64 to move through the driving member 61, so that the defective products of the previous station are transferred to the material tray 82. Then, the qualified product 100 of the previous station is clamped by the transfer member 63, and the product 100 is transferred to the loading position 21 of the carrier 2, thereby completing the loading of the product 100.

[0072] It is mentioned here that the structure of the unloading mechanism 7 in this embodiment is similar to that of the loading mechanism 6, except that the unloading mechanism 7 does not include a defective product transfer member 64, and the transfer member 63 in the unloading mechanism 7 can slide in a direction perpendicular to the fixture plate 62, that is, when all products 100 on a carrier 2 have completed scanning, four products 100 are transferred to the next workstation at one time through the unloading mechanism 7, thereby completing the unloading of the product 100.

[0073] It should be noted that in order to detect the loading accuracy of the product 100, a grating sensor 11 is provided at the loading end of the conveyor line 1. The grating sensor 11 and the loading mechanism 6 are electrically connected to the control system of the laser engraving and scanning equipment of the product, so that the position of the transfer member 63 is detected by the grating sensor 11, and the position of the transfer member 63 is adjusted when there is a position deviation of the transfer member 63, so that the product 100 can be accurately placed inside the carrier 2.

[0074] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
