Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and in particular to a product laser engraving and scanning device. Background Technology

[0002] In manufacturing, laser-engraved QR codes on product surfaces, with initial scanning marking product information, enable subsequent traceability and querying of product information. This improves production line efficiency and accuracy, helps companies track the entire production, distribution, and sales process, enhances management efficiency, and reduces costs. Furthermore, laser-engraved QR codes offer high anti-counterfeiting capabilities, making them difficult to forge and imitate, effectively preventing the emergence of counterfeit and substandard products.

[0003] Existing laser engraving equipment mainly includes a loading robot, an unloading robot, a conveyor line, and a laser engraving machine. The laser engraving machine is located on one side of the conveyor line. During operation, the loading robot transfers the product to the conveyor line, which then transports the product along a preset direction. When the product reaches the side of the laser engraving machine, the machine engraves a QR code on it. After the engraving is complete, the conveyor line continues to transport the product forward, and finally, the unloading robot removes the product from the conveyor line. To improve laser engraving efficiency, the current approach is to increase the number of laser engraving machines along the preset direction, thereby enabling batch laser engraving of products on the conveyor line.

[0004] In practical applications, the dimensions of some products in the preset direction are much smaller than the dimensions of the laser engraving machine in the preset direction. Furthermore, space needs to be reserved between adjacent laser engraving machines for installation and maintenance, resulting in a large distance between adjacent products on the conveyor line. Therefore, sufficient length needs to be reserved at both the beginning and end of the conveyor line to allow for adequate loading and unloading space, leading to a longer conveyor line, excessive space occupation, and increased production costs. In addition, to achieve batch loading and unloading of multiple products with large spacing, multiple loading and unloading robots need to work simultaneously, or longer clamps need to be equipped on both loading and unloading robots, further exacerbating the increase in production costs. Summary of the Invention

[0005] The purpose of this invention is to provide a product laser engraving and scanning device that can perform batch laser engraving on products while reducing the overall size of the device and lowering the production costs for enterprises.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A product laser engraving and scanning device includes a conveyor line and a laser engraving mechanism. The conveyor line can convey products along a first direction. The laser engraving mechanism is disposed on the side of the conveyor line and can laser engrave the products. The conveyor line is provided with multiple carriers, and each carrier is provided with N positions for the products in sequence along the first direction.

[0008] N laser engraving mechanisms are arranged sequentially along the first direction, and the N laser engraving mechanisms are arranged sequentially to correspond to the N carrier positions. Each laser engraving mechanism connects to one carrier at a time and performs laser engraving on the product at the corresponding carrier position.

[0009] Preferably, the product laser engraving and scanning equipment also includes:

[0010] A barcode scanner is provided, with N barcode scanners arranged sequentially along the first direction on the side of the conveyor line. The N barcode scanners are arranged sequentially to correspond to the N carriers. Each barcode scanner connects to one carrier at a time and scans the product at the corresponding carrier.

[0011] Preferably, the N laser engraving mechanisms and the N barcode scanners are located on the same side of the conveyor line, and the N barcode scanners and the N laser engraving mechanisms are spaced apart.

[0012] Preferably, the laser engraving mechanism includes:

[0013] A sliding frame, the sliding frame being capable of sliding along a direction perpendicular to the first direction; and,

[0014] A laser head is disposed on the side of the sliding frame near the conveyor line, and the laser head is capable of laser engraving the product.

[0015] Preferably, the product laser engraving and scanning equipment also includes:

[0016] A removal mechanism is provided for each of the laser engraving mechanisms. The removal mechanism is configured to remove the product to be laser engraved from the carrier position and align the part of the product to be laser engraved with the laser head.

[0017] Preferably, the carrier has multiple positioning slots, each positioning slot forming a mounting position for positioning the product, and the sidewalls of the positioning slots also have multiple receiving slots communicating with the positioning slots; the removal mechanism includes:

[0018] Transfer stand; and,

[0019] The transfer gripper is slidably connected to the transfer base on the side near the laser head. The sliding direction of the transfer gripper is perpendicular to the sliding direction of the sliding frame and the first direction. The transfer gripper has multiple claw parts that can move closer to each other and further away from each other. The multiple claw parts can be inserted into the receiving groove and abut against the side wall of the product.

[0020] Preferably, the product laser engraving and scanning equipment also includes:

[0021] A loading mechanism is configured to transfer multiple products to be laser-engraved to the carrier, wherein the number of products transferred by the loading mechanism at one time is consistent with the number of mounting positions on a single carrier.

[0022] Preferably, the feeding mechanism includes:

[0023] Drive components;

[0024] A clamping plate, the clamping plate being disposed on the driving member, the driving member being capable of driving the clamping plate to move; and...

[0025] A transplanting component, wherein multiple transplanting components are provided on the clamping plate, and the transplanting component is capable of picking up the product.

[0030] The beneficial effects of this invention are:

[0031] The product laser engraving and scanning equipment of this invention optimizes the design of the carrier and the arrangement of the laser engraving mechanisms. Each carrier on the conveyor line has N positions sequentially arranged, and N laser engraving mechanisms are sequentially arranged on the side of the conveyor line. The Nth laser engraving mechanism sequentially engraves the product positioned at the Nth position in each carrier. That is, each laser engraving mechanism connects to one carrier at a time and engraves only one product in a single carrier. After a carrier passes through N laser engraving mechanisms, all products on that carrier have been laser engraved. This ensures that the dimensions of each carrier along the first direction are close to the dimensions of each laser engraving mechanism along the first direction. In other words, only the space required for one laser engraving mechanism in the first direction needs to be reserved at the loading and unloading ends of the conveyor line, thus greatly reducing the product spacing and shortening the overall length of the conveyor line. This not only saves space but also reduces equipment costs. The reduced product spacing also allows for batch loading and unloading using shorter clamps, thereby reducing the cost of automatic loading and unloading. Attached Figure Description

[0044] The following reference Figures 1 to 6 The laser engraving and scanning equipment provided by this invention will be described.

[0045] Reference Figure 1The product laser engraving and barcode scanning equipment includes a base 8, a conveyor line 1, a laser engraving mechanism 3, and a barcode scanner 4. The conveyor line 1, laser engraving mechanism 3, and barcode scanner 4 are all mounted on the base 8. The conveyor line 1 can transport products 100 along a first direction, with one end being the loading end and the other end being the unloading end. The laser engraving mechanism 3 is located to the side of the conveyor line 1 and can perform laser engraving on the products 100 transported to its side by the conveyor line 1. The barcode scanner 4 is located to the side of the conveyor line 1 and can scan the products 100 after being laser engraved by the laser engraving mechanism 3.

[0046] Reference Figure 2 and Figure 3 Furthermore, multiple carriers 2 are provided on the conveyor line 1. Each carrier 2 has N positions 21 arranged sequentially from the loading end to the unloading end, where N is greater than or equal to 2. Each position 21 can position the product 100. N laser engraving mechanisms 3 are arranged sequentially along the first direction on one side of the conveyor line 1. The N laser engraving mechanisms 3 are arranged sequentially corresponding to the N positions 21. Each laser engraving mechanism 3 connects to one carrier 2 at a time and performs laser engraving on the product 100 at the corresponding position 21. Specifically, the carrier position 21 closest to the loading end is the first carrier position 21, and the carrier position 21 furthest from the loading end is the Nth carrier 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 furthest from the loading end is the Nth laser engraving mechanism 3. The first laser engraving mechanism 3 is configured to sequentially engrave the product 100 located at the first carrier position 21 in all carriers 2, and the Nth laser engraving mechanism 3 is configured to sequentially engrave the product 100 located at the Nth carrier position 21 in all 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. The specific distribution method can be adjusted as needed.

[0048] Preferably, in this embodiment, N equals 4 as an example, that is, each carrier 2 is provided with four carrier positions 21 in sequence, and four laser engraving mechanisms 3 are provided in sequence 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 equipment starts working, the first carrier 2, which has four positions 21, loads four products 100 and is then transported by the conveyor line 1 to the position where it docks with the first laser engraving mechanism 3. At this time, the first laser engraving mechanism 3 performs laser engraving on the product 100 on the first carrier 2 located at the first position 21. Then, the conveyor line 1 transports the first carrier 2 to the position where it docks with the second laser engraving mechanism 3. The second carrier 2, located upstream of the first carrier 2, docks with the first laser engraving mechanism 3. At this time, the second laser engraving mechanism 3 performs laser engraving on the product 100 on the first carrier 2 located at the second position 21, while the first laser engraving mechanism 3 performs laser engraving on the product 100 on the second carrier 2 located at the first position 21.

[0050] Then, the conveyor line 1 transports the first carrier 2 to the position where it docks with the third laser engraving mechanism 3. 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 located at the third position 21 on the first carrier 2, the second laser engraving mechanism 3 performs laser engraving on the product 100 located at the second position 21 on the second carrier 2, and the first laser engraving mechanism 3 performs laser engraving on the product 100 located at the first position 21 on the third carrier 2.

[0051] Similarly, when conveyor line 1 transports 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 located at the fourth position 21 on the first carrier 2, while the third laser engraving mechanism 3 performs laser engraving on the product 100 located at the third position 21 on the second carrier 2, the second laser engraving mechanism 3 performs laser engraving on the product 100 located at the second position 21 on the third carrier 2, and the first laser engraving mechanism 3 performs laser engraving on the product 100 located at the first 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 scanning equipment has officially entered the assembly line operation. When the conveyor line 1 continues to transport carrier 2, the products 100 on subsequent carrier 2 are laser-engraved in sequence according to the above order. Each time the conveyor line 1 moves forward, the length of the single carrier 2 in the first direction is the same as the length of the transport distance. All four laser engraving mechanisms 3 work synchronously to perform batch laser engraving on the products 100.

[0053] Based on the above, in this invention, four laser engraving mechanisms 3 engrave the product 100 on each carrier 2 in four separate steps. Each laser engraving mechanism 3 engages with only one carrier 2 at a time, ensuring that the dimensions of each carrier 2 along the first direction are close to the dimensions of each laser engraving mechanism 3 along the first direction. This means that only the space required for one laser engraving mechanism 3 in the first direction needs to be reserved at the loading and unloading ends of the conveyor line 1. Compared to existing arrangements, where four laser engraving mechanisms 3 need to be reserved in the first direction at the loading and unloading ends of the conveyor line 1, the required length at the loading and unloading ends is significantly reduced, thus shortening the overall length of the conveyor line 1. This not only saves space required for the product laser engraving and scanning equipment but also reduces the cost of the conveyor line 1.

[0054] Reference Figure 2 Furthermore, N barcode scanners 4 are sequentially arranged along the first direction on one side of the conveyor line 1. Specifically, the barcode scanner 4 closest to the loading end is the first barcode scanner 4, and the barcode scanner 4 furthest from the loading end is the Nth barcode scanner 4. The first barcode scanner 4 is configured to scan the products 100 located at the first position 21 in all carriers 2 sequentially, and the Nth barcode scanner 4 is configured to scan the products 100 located at the Nth position 21 in all carriers 2 sequentially. By using the barcode scanners 4 to scan the laser-engraved products 100, the information of the successfully scanned products 100 is entered, and the products 100 that fail to scan are marked so that they can be laser-engraved again or directly scrapped. Thus, the barcode scanners 4 are integrated on the base 8, making the equipment more integrated. Since the number of barcode scanners 4 is the same as the number of laser engraving mechanisms 3, that is, in this embodiment, four barcode scanners 4 are also provided, so the product 100 can be scanned in batches by referring 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 one time.

[0055] To make the laser engraving and scanning equipment for this product more compact, in this embodiment, four scanners 4 and four laser engraving mechanisms 3 are spaced apart, that is, a single scanner 4 is arranged between two adjacent laser engraving mechanisms 3, which can greatly reduce the space required for the four scanners 4 in the first direction. Furthermore, since a period of time is required after laser engraving the product before scanning, in this embodiment, the first scanner 4 is located between the second and third laser engraving mechanisms 3, and so on. The second scanner 4 is located between the third and fourth laser engraving mechanisms 3, the third scanner 4 is downstream of the fourth laser engraving mechanism 3, and the fourth scanner 4 is 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 significantly reduces the space required for the four barcode scanners 4 in the first direction compared to 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 reduce the size of the product's laser engraving and barcode scanning equipment in the first direction.

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

[0058] Reference Figure 2 and Figure 3 For example, in this embodiment, the conveyor line 1 is a chain conveyor mechanism, and the carrier 2 is positioned on the chain plate of the chain conveyor mechanism. Multiple carriers 2 are arranged on the outer ring of the chain plate, and all carriers 2 circulate. Each carrier 2 has multiple positioning slots 22 along its length on the surface away from the chain plate. The positioning slots 22 are arranged in a square shape. In this embodiment, four are used as an example. Each positioning slot 22 forms a position 21 for positioning the product 100, so that four 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 multiple receiving grooves 23 communicating with the positioning groove 22 are also provided on the circumferential side wall of each positioning groove 22. In this embodiment, four are used as an example, that is, one receiving groove 23 is provided for each side of the product 100.

[0060] The positioning groove 22, which can be fully embedded in the product 100, improves the positioning effect of the product 100 and also protects the product 100. The receiving groove 23 facilitates the insertion of a clamp to grip the product 100. The area on the product 100 to be laser-engraved can also be exposed through the receiving groove 23, allowing the barcode scanner 4 to directly scan the product 100 within the carrier 21. Optionally, in some other embodiments, the depth of the positioning groove 22 can be reduced to expose the area on the product 100 to be laser-engraved.

[0061] Reference Figure 4Each 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 lead 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 lead screw module 33. The driving direction of the lead 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 a hydraulic cylinder or a pneumatic cylinder. The laser head 32 is connected to the side of the sliding frame 31 near the conveyor line 1. The laser head 32 can perform laser engraving on the product 100, and the emitting 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 burning the carrier 2 and other products 100 during operation, the product laser engraving and scanning equipment also includes a removal mechanism 5. A material transfer bracket 81 is provided on the base 8. The material transfer bracket 81 is located on the side of the conveyor line 1 away from the laser engraving mechanism 3. One removal mechanism 5 is provided on the material transfer bracket 81 for each laser engraving mechanism 3. The removal mechanism 5 is configured to remove the product 100 from the carrier position 21 and align the part of the product 100 to be laser engraved with the laser head 32.

[0063] Specifically, the transfer mechanism 5 includes a transfer base 51 and a transfer gripper 52. The transfer base 51 is connected to the transfer bracket 81, and the transfer gripper 52 is slidably connected to the side of the transfer base 51 near the laser head 32. The sliding direction of the transfer gripper 52 is perpendicular to the sliding direction of the sliding frame 31 and the first direction. In this embodiment, the transfer gripper 52 slides in a vertical direction, and the sliding of the transfer gripper 52 is driven by a cylinder. In some other embodiments, the sliding of the transfer gripper 52 can also be driven by an electric cylinder or a hydraulic cylinder.

[0064] Furthermore, the transfer gripper 52 has multiple claw portions 521 that can approach and move away from each other. These claw portions 521 can be inserted into the receiving groove 23 and abut against the side wall of the product 100. In this embodiment, the transfer gripper 52 is a pneumatic gripper connected to the piston rod of a cylinder. The pneumatic gripper has four claw portions 521, meaning one claw portion 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 on the first carrier position 21 of the carrier 2 arrives at one side of the laser engraving mechanism 3, the transfer gripper 52 is first driven by the cylinder to move downward, so that the claw part 521 of the transfer gripper 52 extends into the receiving groove 23 and clamps the product 100. Then the transfer gripper 52 moves upward until the position on the product 100 to be laser engraved is aligned with the laser head 32. At this time, the laser head 32 performs laser engraving on the product 100. Then the removal mechanism 5 puts the product 100 back into the first carrier position 21. While clamping the product 100, the transfer gripper 52 also plays a role in precise positioning of the product 100, that is, the four claw parts 521 respectively abut against the four side walls of the product 100, so that the product 100 is precisely positioned.

[0066] In addition, each transfer station 51 is covered with a fume hood 53, which is connected to the transfer station 51 and is connected to the factory's flue through a pipe to exhaust the smoke generated during laser engraving.

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

[0068] Reference Figure 1 and Figure 6 To facilitate loading and unloading on conveyor line 1, the product laser engraving and scanning equipment also includes a loading mechanism 6 and an unloading mechanism 7. The loading mechanism 6 is configured to transfer multiple products 100 to be laser engraved to carrier 2. The number of products 100 transferred by the loading mechanism 6 at a time is the same as 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 remove multiple laser-engraved products 100 from carrier 2. The number of products 100 transferred by the unloading mechanism 7 at a time is the same as 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 drive unit 61, a clamping plate 62, a transfer component 63, and a defective product transfer component 64. The drive unit 61 can drive the clamping plate 62 to move, and the clamping plate 62 is rotatably connected to the drive unit 61. In this embodiment, the drive unit 61 is a robotic arm, and the rotation axis of the clamping plate 62 is perpendicular to the surface of the clamping plate 62. Multiple transfer components 63 are connected to the clamping plate 62. In this embodiment, four are used as an example. The four transfer components 63 are arranged along the length direction of the clamping plate 62, that is, the arrangement direction of the four transfer components 63 is perpendicular to the rotation axis of the clamping plate 62. In this embodiment, the transfer component 63 is a pneumatic gripper. In other embodiments, the transfer component 63 may also be a suction nozzle or an electromagnet.

[0070] Furthermore, the defective product transfer component 64 is connected to the clamp plate 62 or the transfer component 63. The defective product transfer component 64 can pick up the defective product 100. In this embodiment, the defective product transfer component 64 is also a pneumatic gripper and is connected to one of the transfer components 63. In some other embodiments, the transfer component 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. The drawer 83 contains a material tray 82. When the loading mechanism 6 is working, it first clamps the defective product from the previous station using the defective product transfer component 64, and then drives the defective product transfer component 64 to move through the drive component 61, so that the defective product from the previous station is transferred into the material tray 82. Then, the transfer component 63 clamps the qualified product 100 from the previous station and transfers the product 100 into the loading position 21 of the carrier 2, thereby completing the loading of the product 100.

[0072] It should be noted that the structure of the unloading mechanism 7 in this embodiment is similar to that of the loading mechanism 6. The difference is that the unloading mechanism 7 does not include the defective product transfer component 64, and the transfer component 63 in the unloading mechanism 7 can slide in a direction perpendicular to the clamp plate 62. That is, when all the products 100 on a carrier 2 have been scanned, the unloading mechanism 7 transfers the four products 100 to the next workstation at one time, thereby completing the unloading of the products 100.

[0073] It should be noted that, in order to detect the accuracy of product 100 feeding, a grating sensor 11 is installed on the feeding end of the conveyor line 1. The grating sensor 11 and the feeding mechanism 6 are both electrically connected to the control system of the laser engraving and scanning equipment of the product. The position of the transfer part 63 is detected by the grating sensor 11, and the position of the transfer part 63 is adjusted when there is a positional deviation, so that 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 implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
