[0002] In the 3C product manufacturing industry, laser engraving of serial numbers (SN codes) is a crucial process for product identification. Currently, the industry commonly uses semi-automated laser engraving equipment, whose workflow requires manual intervention in loading and unloading: operators must place products on the production line sequentially at laser engraving stations #1 and #2, activate the system via a double-start button, causing the product to enter the position corresponding to the laser engraving mechanism. The laser engraving mechanism then engraves the product, and after completion, the product is ejected. The engraved product is then manually removed, and products awaiting laser engraving are manually placed in. This model has significant limitations: First, manual loading and unloading consumes considerable manpower, resulting in high labor costs; second, it requires high levels of human-machine coordination, as the operator's pace directly affects the equipment's pace, limiting its efficiency; third, the current equipment's processing speed cannot keep up with the product turnover speed, making it difficult to match the speed requirements of modern production lines; fourth, the equipment lacks flexibility, as existing equipment cannot achieve multi-model co-production, severely restricting production line flexibility and capacity expansion.

[0014] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0015] Please see Figures 1 to 3 The laser engraving equipment 100 of this utility model includes a frame 101 and a feeding conveyor 1, a first distributing conveyor 2, a laser engraving conveyor line 3, a laser engraving mechanism 4, a second distributing conveyor 5, and a discharging conveyor 6 respectively disposed on the frame 101. The feeding conveyor 1, the first distributing conveyor 2, the laser engraving conveyor line 3, the second distributing conveyor 5, and the discharging conveyor 6 are arranged sequentially along a conveying direction, and a plurality of laser engraving conveyor lines 3 are arranged in parallel between the first distributing conveyor 2 and the second distributing conveyor 5. Each laser engraving conveyor line 3 is equipped with... Several laser engraving stations 31 are provided, each with a corresponding laser engraving mechanism 4. A loading conveyor 1 loads workpieces onto a first distributing conveyor 2, which then distributes the workpieces to one of the laser engraving conveyor lines 3. The laser engraving conveyor line 3 transports the workpieces to the corresponding laser engraving station 31. The laser engraving mechanism 4 performs laser engraving on the workpieces located at the laser engraving station 31. A second distributing conveyor 5 distributes the laser-engraved workpieces from each laser engraving conveyor line 3 to an unloading conveyor 6, which unloads the workpieces. The conveying direction can be a straight line, but is not limited to this; for example, it can also be a winding or meandering direction.

[0016] In this embodiment, there are two laser engraving conveyor lines 3, but this is not a limitation. Each laser engraving conveyor line 3 includes several sequentially connected roller conveyor modules. Specifically, there are three roller conveyor modules, and each roller conveyor module has a corresponding laser engraving station 31. Therefore, a single laser engraving conveyor line 3 has three laser engraving stations 31, and each laser engraving station 31 has a laser engraving mechanism 4. Thus, for the two laser engraving conveyor lines 3 of this application, there are a total of six laser engraving mechanisms 4, which can match the overall cycle time and can increase the cycle time to 12s / pcs, but this is not a limitation. Furthermore, an infeed sensor 32 is provided at the initial conveying end position of each roller conveyor module. The infeed sensor 32 is used to detect whether the workpiece has entered the roller conveyor module.

[0017] Please see Figure 1 and Figure 2 In one embodiment, the laser engraving equipment 100 further includes a barcode scanner 7 and a controller 101a. The barcode scanner 7 is mounted on the frame 101 and located above the feeding conveyor mechanism 1. The controller 101a is electrically connected to the barcode scanner 7 and the laser engraving mechanism 4. The barcode scanner 7 scans the workpiece located on the feeding conveyor mechanism 1 and feeds back the scanned information to the controller 101a. The controller 101a controls the laser engraving mechanism 4 to laser engrave the corresponding information on the workpiece based on the scanned information. The barcode scanner 7 can also verify the workpiece model, batch number, and other information in real time by reading the barcode / QR code on the workpiece, achieving accurate identification and error prevention.

[0018] Furthermore, the controller 101a is electrically connected to the MES system (not shown in the figure). The controller 101a feeds back the scanned information to the MES system, which in turn feeds back the corresponding laser engraving information to the controller 101a. The controller 101a then controls the laser engraving mechanism 4 to perform laser engraving on the workpiece based on this information. The barcode scanner 7 interfaces with the MES system through the controller 101a, exchanging laser engraving information and achieving information exchange. The backend can monitor the information exchange. Specifically, the barcode scanner 7 scans the workpiece located on the feeding conveyor 1 and feeds back the scanned information to the controller 101a. The controller 101a feeds back the scanned information to the MES system, which in turn feeds back the corresponding laser engraving information to the controller 101a. The controller 101a then controls the laser engraving mechanism 4 to perform laser engraving on the workpiece based on this information. The MES system can also correlate production data and compare it with preset standards.

[0019] Please see Figure 2In one embodiment, the laser engraving equipment 100 further includes an alarm light 101b, a display 101c, and a mouse and keyboard module 101d respectively disposed on the frame 101. The cover opening mechanism 8, the alarm light 101b, the display 101c, and the mouse and keyboard module 101d are electrically connected to the controller 101a. The alarm light 101b is used to provide an alarm prompt for production errors, the display 101c can display production information, and the mouse and keyboard module 101d is used by the operator for information input processing.

[0020] Please see Figure 2 In one embodiment, the laser engraving equipment 100 further includes a cover-opening mechanism 8, which is disposed on the frame 101 and located above the feeding conveyor mechanism 1. The cover-opening mechanism 8 is used to adsorb and open a folded workpiece on the feeding conveyor mechanism 1 or to adsorb and close a workpiece in an unfolded state on the feeding conveyor mechanism 1. Taking a laptop computer as an example, a laptop computer has two states: a folded state and an unfolded state. When a laptop computer enters the feeding conveyor mechanism 1, it is usually in a folded state. The barcode / QR code information of the laptop computer is usually on the inside of the fold. Therefore, by setting the cover-opening mechanism 8, the folded workpiece on the feeding conveyor mechanism 1 can be adsorbed and opened, so that the barcode scanner 7 can scan the barcode / QR code information of the laptop computer. The opening mechanism 8 can adopt a structure in which a moving module and a vacuum adsorption module are connected and cooperated. The moving module drives the vacuum adsorption module to move, so that the vacuum adsorption module moves to the position corresponding to the workpiece, so that the vacuum adsorption module adsorbs the folded side of the workpiece. Then, the moving module drives the vacuum adsorption module to move, thereby causing the folded side of the workpiece to rotate and open, so that the barcode scanner 7 can scan the workpiece.

[0021] Please see Figure 1 and Figure 2 In one embodiment, the first material conveying mechanism 2 includes a first translation drive module 21 and a first translation conveyor line 22. The first translation drive module 21 is mounted on the frame 101, and the first translation conveyor line 22 is mounted on the first translation drive module 21. The first translation drive module 21 drives the first translation conveyor line 22 to move, so that the first translation conveyor line 22 docks with the loading conveyor mechanism 1 or with one of the laser engraving conveyor lines 3. The first translation conveyor line 22 is used to pick up the workpiece conveyed by the loading conveyor mechanism 1 and to convey the workpiece to one of the laser engraving conveyor lines 3. The first translation drive module 21 can be an existing linear drive module, and the first translation conveyor line 22 can be an existing conveyor belt line, but is not limited thereto.

[0022] Please see Figure 1 as well as Figures 3 to 6In one embodiment, the laser engraving equipment 100 further includes a positioning module 9, which is disposed on the frame 101, and each laser engraving station 31 is provided with a corresponding positioning module 9. The positioning module 9 is used to position the workpiece located on the laser engraving station 31.

[0023] Specifically, the positioning module 9 includes a lifting blocking positioning component 91, a lifting front and rear side push component 92, a left and right blocking positioning component 93, and a left and right side push component 94, which are respectively disposed on the frame 101. The lifting blocking positioning component 91 and the lifting front and rear side push component 92 are respectively arranged on the front and rear sides of the laser engraving station 31, and the left and right blocking positioning component 93 and the left and right side push component 94 are respectively arranged on the left and right sides of the laser engraving station 31. The lifting blocking positioning component 91 blocks the workpiece located at the laser engraving station 31 from moving forward, so that the lifting front and rear side push component 92 pushes the workpiece located at the laser engraving station 31 to be aligned with the lifting blocking positioning component 91, and the left and right side push component 94 pushes the workpiece located at the laser engraving station 31 to be aligned with the left and right blocking positioning component 93. After the workpiece is conveyed to the corresponding laser engraving station 31 by the laser engraving conveyor line 3, the lifting and blocking positioning component 91 descends to block the workpiece located at the laser engraving station 31 from moving forward, causing the workpiece to stop at the laser engraving station 31. Then, the lifting and pushing component 92 pushes the workpiece located at the laser engraving station 31 onto the lifting and blocking positioning component 91, thereby positioning the workpiece in the front-back direction. The left and right pushing component 94 pushes the workpiece located at the laser engraving station 31 onto the left and right blocking positioning component 93, thereby positioning the workpiece in the left and right direction. For example, the lifting and blocking positioning component 91 can adopt a structure in which a telescopic cylinder drives a blocking component to rise and fall, the lifting and pushing component 92 and the left and right pushing component 94 can adopt a structure in which a telescopic cylinder drives a pushing component to move, and the left and right blocking positioning component 93 can adopt a structure in which a fixed positioning component is used, but it is not limited to these.

[0024] Furthermore, the positioning module 9 also includes a lifting component 95, which is mounted on the frame 101 and used to lift the workpiece located at the laser engraving station 31. By lifting the workpiece at the laser engraving station 31 using the lifting component 95, the workpiece is lifted away from the laser engraving conveyor line 3, thus facilitating laser engraving by the laser engraving mechanism 4. Initially, the lifting part of the lifting component 95 is located below the laser engraving conveyor line 3. When it is necessary to lift the workpiece, the lifting component 95 drives its lifting part to rise and pass through the gap inside the laser engraving conveyor line 3, thereby lifting the workpiece on the laser engraving conveyor line 3, but this is not a limitation. For example, the lifting component 95 can adopt a structure where a lifting cylinder drives a lifting element to rise and fall, but this is not a limitation.

[0025] Furthermore, the positioning module 9 also includes a height positioning component 96, which is mounted on the frame 101 and positioned above the laser engraving conveyor line 3. The lifting component 95 can lift and align the workpiece located at the laser engraving station 31 to the height positioning component 96, ensuring that the workpiece is positioned at a precise height, thereby enabling the laser engraving mechanism 4 to accurately and effectively engrave the workpiece. Additionally, by setting the height positioning component 96, the laser engraving equipment 100 of this invention can be applied to products of different thicknesses, ensuring that the upper surface of workpieces of different thicknesses can be positioned at a consistent height, thus ensuring that the laser engraving mechanism 4 can accurately and effectively engrave the workpiece, guaranteeing the laser engraving effect. Simultaneously, the laser engraving height positioning is precise, with an accuracy of ±0.1mm, and the product lifting method is compatible with products of different specifications.

[0026] Furthermore, the positioning module 9 also includes a height limiting component 97, which is mounted on the frame 101. The height limiting component 97 is used to limit the lifting height of the lifting component 95. Since the lifting height of the lifting component 95 varies for products of different thicknesses, the height limiting component 97 limits the lifting height of the lifting component 95, preventing it from lifting the workpiece too high. For example, the height limiting component 97 can use an existing elastic limiting module, but is not limited to this.

[0027] Please see Figure 3 In one embodiment, the laser head of the laser engraving mechanism 4 has a replaceable structure. The laser head is compatible with red light, green light, purple light, and CO2, and can be replaced according to the product material.

[0028] Please see Figure 3 In one embodiment, the laser engraving equipment 100 further includes a laser engraving height adjustment mechanism 41, which is mounted on the frame 101 and connected to the laser engraving mechanism 4. The laser engraving height adjustment mechanism 41 is used to adjust the height of the laser engraving mechanism 4. The laser engraving height adjustment mechanism 41 can be an existing linear motion lifting module.

[0029] Furthermore, such as Figure 4 as well as Figure 6 As shown, each laser engraving station 31 is equipped with a laser engraving anti-fall component 42. The laser engraving anti-fall component 42 is set on the frame 101 and located below the laser engraving mechanism 4. The laser engraving anti-fall component 42 can prevent the laser engraving mechanism 4 from falling.

[0030] Please see Figure 1In one embodiment, the second material conveying mechanism 5 includes a second translation drive module 51 and a second translation conveyor line 52. The second translation drive module 51 is mounted on the frame 101, and the second translation conveyor line 52 is mounted on the second translation drive module 51. The second translation drive module 51 drives the second translation conveyor line 52 to move, so that the second translation conveyor line 52 docks with the unloading conveyor mechanism 6 or with one of the laser engraving conveyor lines 3. The second translation conveyor line 52 is used to pick up the workpiece conveyed by the laser engraving conveyor line 3 and to convey the workpiece to the unloading conveyor mechanism 6. The second translation drive module 51 can be an existing linear drive module, and the second translation conveyor line 52 can be an existing conveyor belt line, but is not limited thereto.

[0031] Please see Figure 1 In one embodiment, the laser engraving equipment 100 of this utility model further includes a laser engraving water cooling box 43, which is connected to the laser engraving mechanism 4 and is used to cool the laser engraving mechanism 4 with water.

[0032] Combination Figures 1 to 6 The specific working principle of the laser engraving equipment 100 of this utility model is as follows: The feeding conveyor 1 and the unloading conveyor 6 are connected to the product production lines before and after. The opening mechanism 8 is used to open the workpiece on the feeding conveyor 1, so that the workpiece changes from a folded state to an open state. Then, the barcode scanner 7 scans the workpiece on the feeding conveyor 1 and feeds the scan information back to the controller 101a. After that, the opening mechanism 8 closes the workpiece, so that the workpiece changes from a folded state back to a folded state. The workpiece is then picked up by the feeding conveyor 1 and fed into the conveyor, allowing it to flow to the first distributing conveyor 2. The first distributing conveyor 2 distributes the workpieces from the feeding conveyor 1 to one of the laser engraving conveyor lines 3. The laser engraving conveyor line 3 then transports the workpieces to the corresponding laser engraving station 31. The lifting and blocking positioning component 91 of the positioning module 9 descends and blocks the workpieces located at the laser engraving station 31 from moving forward. Then, the lifting and pushing component 92 pushes the workpieces located at the laser engraving station 31 to the lifting and blocking positioning component 91, and the left and right pushing component 94 pushes the workpieces located at the laser engraving station 31 to the left and right blocking positioning component 93, thereby positioning the workpieces in the front-back and left-right directions. Then, the lifting component 95 lifts the workpieces located at the laser engraving station 31, causing them to leave the laser engraving conveyor line 3 and rise to the position of the height positioning component 96. Finally, the laser engraving mechanism 4 performs laser engraving on the workpieces. After laser engraving is completed, the lifting component 95 lowers the workpiece onto the laser engraving conveyor line 3. The lifting blocking positioning component 91, the lifting front and rear side push component 92, and the left and right side push component 94 all retract to their original positions, thereby releasing the workpiece. This allows the laser engraving conveyor line 3 to transport the workpiece to the second material distribution conveyor 5. The second material distribution conveyor 5 then distributes the workpiece to the unloading conveyor 6, which in turn unloads the laser-engraved workpiece.

[0033] In summary, the laser engraving equipment 100 of this invention can achieve automated loading and unloading, effectively reducing labor costs. Furthermore, the laser engraving equipment 100 can be directly integrated into the production line, eliminating the need for off-line operations, effectively matching the overall production rhythm and improving production efficiency. Secondly, by setting up a barcode scanner to scan the workpiece, the laser engraving equipment 100 can be integrated into the MES system, thereby exchanging laser engraving information and achieving information interoperability. Additionally, the laser engraving equipment 100 uses a positioning module to position the workpiece and fix the laser engraving height, thus ensuring the laser engraving effect on the workpiece.

[0034] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
