TECHNICAL FIELD

[0001] The present application relates to the technical field of laser marking equipment, and in particular to an automatic type changing laser marking equipment. BACKGROUND

[0002] Laser marking technology is widely used in modern manufacturing, especially in precision manufacturing and high value-added product identification. With the diversification of market demand and the progress of technology, laser marking equipment not only needs to be efficient and accurate, but also must be able to adapt to the rapid type changing needs of different specifications of workpieces.

[0003] In order to cope with the problem of frequent type changing of multi-variety workpieces, the related technology usually adopts the way of manually replacing the clamp and switching the processing program. Specifically, when different types of workpieces need to be processed, the operator needs to manually adjust the tooling clamp and select the corresponding processing program through manual intervention. Although this method can meet the flexibility requirements of production to some extent, it still exposes some problems in actual application. For example, the process of manually replacing the clamp takes a long time, which easily leads to the stop of the production line and increases the non-production time; in addition, frequent manual type changing not only consumes a lot of time and manpower, but also increases the production cost and affects the market competitiveness of enterprises. CONTENT OF THE UTILITY MODEL

[0004] In order to reduce the time required for laser marking type changing, the present application provides an automatic type changing laser marking equipment.

[0005] The automatic type changing laser marking equipment provided by the present application adopts the following technical scheme:

[0006] An automatic type changing laser marking equipment, comprising a mounting frame, a laser marking assembly and a control assembly, the automatic type changing laser marking equipment has a marking station, one side of the mounting frame is provided with a workpiece conveying assembly, the workpiece conveying assembly is used to send a workpiece to be marked to the marking station, or send a workpiece that has completed marking away from the marking station, a lifting adjusting assembly is arranged on the mounting frame, the lifting adjusting assembly is used to drive the laser marking assembly to reciprocate along the vertical direction, a workpiece detection assembly is arranged on the side of the lifting adjusting assembly close to the workpiece conveying assembly, the workpiece detection assembly is used to detect the type of the workpiece at the marking station, and the control assembly is signal connected with the workpiece conveying assembly, the lifting adjusting assembly and the laser marking assembly.

[0007] By adopting the technical scheme, the marking program can be quickly switched between different workpieces, the type changing time is significantly reduced, and the production efficiency is greatly improved. Specifically, the workpiece conveying assembly can accurately convey the workpiece to be marked to the marking station or convey the workpiece that has completed marking away from the marking station, ensuring the smooth flow of the workpiece. The workpiece detection assembly detects the shape of the workpiece in real time to determine the type of the workpiece, and then sends the determination result to the control assembly. The control assembly serves as the center of the whole system, receives and coordinates the work of each component, and switches the marking program according to the determination result, realizing automatic program switching, reducing the need for manual intervention, and improving the type changing speed. The lifting adjusting assembly enables the laser marking assembly to adjust its position according to the selected program, ensuring the accuracy of marking.

[0008] Optionally, the workpiece detection assembly comprises a high-position photoelectric sensor and a low-position photoelectric sensor, the high-position photoelectric sensor and the low-position photoelectric sensor are located at the same horizontal distance from the center of the marking station, and the height of the high-position photoelectric sensor in the vertical direction is higher than that of the low-position photoelectric sensor.

[0009] By adopting the technical scheme, the workpiece detection assembly can determine the structure of the workpiece at different height positions, and thus quickly identify different types of workpieces according to the obtained structure. The high-position photoelectric sensor and the low-position photoelectric sensor are located at different heights, ensuring effective detection of different height positions of the workpiece.

At the same time, the horizontal arrangement of the laser generator and the marking lens makes the marking process more stable and reliable, improving the accuracy and efficiency of marking.

[0012] Optionally, the workpiece conveying assembly comprises a conveying belt and a lifting platform, the lifting platform and the conveying belt are fixedly connected, and the conveying belt is used to drive the lifting platform to approach or move away from the marking station.

[0013] By adopting the technical scheme, the workpiece conveying assembly is designed to enable the workpiece to move smoothly on the conveying belt, and the workpiece is accurately positioned and quickly transmitted through the cooperation of the lifting platform, thereby improving the automation degree and work efficiency of laser marking.

[0015] By adopting the technical scheme, the high-position scanning code device and the low-position scanning code device correspond to two different types of workpieces, respectively. After the workpiece detection assembly determines the type of the workpiece and the control assembly switches the program, the high-position scanning code device and the low-position scanning code device can be started and scanning detection can be performed on different types of workpieces, thereby improving the pertinence and accuracy of detection.

[0016] Optionally, the scanning code assembly is signal-connected with the control assembly.

[0017] By adopting the technical scheme, the scanning code assembly can determine whether the code marking is qualified. If the code marking is qualified, the characteristic code is bound with the workpiece and uploaded to the cloud for data recording through the control assembly. If the code marking is not qualified, the unqualified product can be sent away from the marking station by the workpiece conveying assembly, and handled by the staff.

Detailed Implementation

[0024] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.

[0025] This application discloses an automatic type-changing laser marking device.

[0026] like Figure 1 As shown, the automatic type-changing laser marking equipment includes a mounting frame 1, a laser marking component, and a control component. The automatic type-changing laser marking equipment has a marking station. A workpiece conveying component is provided on one side of the mounting frame 1. The workpiece conveying component is used to send the workpiece 13 to be marked to the marking station, or to send the workpiece that has been marked away from the marking station. A lifting adjustment component is provided on the mounting frame 1. The lifting adjustment component is used to drive the laser marking component to move back and forth in the vertical direction. A workpiece detection component is provided on the side of the lifting adjustment component near the workpiece conveying component. The workpiece detection component is used to detect the model of the workpiece at the marking station. The control component is simultaneously connected to the workpiece conveying component, the lifting adjustment component, and the laser marking component.

[0027] This application possesses the ability to quickly switch marking programs between different workpieces, significantly reducing changeover time and thus greatly improving production efficiency. Specifically, the workpiece conveying component can accurately transport the workpiece 13 to be marked to the marking station, or remove marked workpieces from the marking station, ensuring smooth workpiece flow. The workpiece detection component identifies the workpiece model by real-time detection of the workpiece shape and transmits the identification result to the control component. As the core of the system, the control component is responsible for receiving and coordinating the work of each component. The control component can be implemented through a PLC controller or embedded computer, possessing data processing and real-time control capabilities. The control component receives signals from the workpiece detection component, automatically selects the corresponding marking program based on the detection results, and sends instructions to the laser marking component, workpiece conveying component, and lifting adjustment component through the communication interface, realizing automated changeover, reducing the need for manual intervention, and improving changeover efficiency. The lifting adjustment component enables the laser marking component to adjust its position according to the selected program, ensuring marking accuracy.

[0028] like Figure 1As shown, the mounting frame 1 includes a frame structure and a support plate. The frame structure is made of high-strength aluminum alloy material to ensure the stability and durability of the entire device. The support plate is located at the top of the frame structure and is used to mount other components. The height of the frame structure can be adjusted according to actual needs to adapt to different heights of workpieces. In order to protect the remaining working components, the support plate can also be provided with a marking chamber (not shown in the figure) for accommodating the remaining working components.

[0029] As shown in Figure 1 , the workpiece detection assembly includes a high-position photoelectric sensor 2 and a low-position photoelectric sensor 3. The horizontal distance between the high-position photoelectric sensor 2 and the low-position photoelectric sensor 3 and the center position of the marking station is the same, and the height of the high-position photoelectric sensor 2 in the vertical direction is higher than that of the low-position photoelectric sensor 3. This arrangement can determine the distance between the outer surface of the workpiece at different height positions and the sensor, thereby determining the structure of the workpiece at different height positions, and then combining the structures obtained at two different height positions to determine the model of the workpiece. This design not only improves the detection accuracy, but also reduces the misjudgment rate and improves the model changing efficiency.

[0030] As shown in Figure 1 , the workpiece conveying assembly includes a conveyor belt 8 and a lifting platform 9. The lifting platform 9 is fixedly connected with the conveyor belt 8, and the conveyor belt 8 can stably convey the lifting platform 9. The lifting of the lifting platform 9 is realized by an electric push rod in this application, and in some other embodiments, the lifting platform 9 can also be moved up and down by an oil cylinder or an air cylinder. In addition, the speed of the conveyor belt 8 can be adjusted, and the production rhythm can be flexibly adjusted.

[0031] As shown in Figure 1 , the lifting adjusting assembly includes a guide portion 4 arranged in the vertical direction and a moving portion 5 capable of reciprocating along the direction of the guide portion 4. The guide portion 4 can adopt a linear guide rail, and the moving portion 5 can adopt a slider with a ball screw. The laser marking assembly is fixed on the slider, and the ball screw is driven to rotate by a servo motor, thereby driving the slider to move up and down along the linear guide rail. Such design not only ensures the accuracy and stability of the movement, but also can adjust the position of the laser marking assembly according to the selected program. The lifting adjusting assembly can realize the reciprocating movement of the moving portion 5 along the guide portion 4, and the specific structure is not limited by the application.

[0032] As shown in Figure 1 , the laser marking assembly includes a laser generator 6 and a marking lens 7. The laser generator 6 is arranged in the horizontal direction and is fixedly connected with the moving portion 5, and the irradiation angle of the marking lens 7 is arranged in the horizontal direction and points to the marking station. The laser generator 6 can select a continuous wave laser or a pulse laser, depending on the required precision and speed of marking. The marking lens 7 adopts a high-precision optical lens group to ensure good focusing of the laser beam and clear marking effect.

[0033] like Figure 1 As shown, in order to detect the marking effect, the automatic type-changing laser marking equipment provided in this application embodiment also includes a barcode scanning component. The barcode scanning component is signal-connected to the control component. The barcode scanning component includes an auxiliary frame 10 and a high-position barcode scanner 11 and a low-position barcode scanner 12 disposed on the auxiliary frame 10. The high-position barcode scanner 11 and the low-position barcode scanner 12 are at the same horizontal distance from the center position of the marking station, and the high-position barcode scanner 11 is higher than the low-position barcode scanner 12 in the vertical direction.

[0034] The high-position barcode scanner 11 and the low-position barcode scanner 12 correspond to two different workpiece models. After the workpiece detection component determines the workpiece model and the control component switches the program, the high-position barcode scanner 11 and the low-position barcode scanner 12 can be activated separately for different workpiece models and perform barcode scanning detection. The barcode scanning detection can determine whether the marking is qualified. If it is qualified, the control component binds the feature code to the workpiece and uploads it to the cloud for data recording. If it is unqualified, the workpiece conveyor component can send the unqualified product away from the marking station for processing by the staff.

[0035] The implementation principle of an automatic type-changing laser marking device according to an embodiment of this application is as follows:

[0036] The installation equipment at the preparation station will install the workpiece 13 to be marked at the lifting platform 9.

[0037] The workpiece conveying assembly operates, using conveyor belt 8 and lifting platform 9 to smoothly transport the workpiece 13 to be marked to the marking station. At this time, the high-position photoelectric sensor 2 and low-position photoelectric sensor 3 in the workpiece detection assembly begin to detect the workpiece. By measuring the distance between the outer surface of the workpiece and the sensor, and combining the structural information obtained from the two different height positions, the accurate determination of the workpiece model is achieved.

[0038] After receiving a signal from the workpiece detection component, the control component quickly analyzes it and automatically selects a marking program that matches the workpiece model. Subsequently, the control component sends commands to the laser marking component, workpiece conveying component, and lifting and adjusting component via the communication interface, coordinating the start of operation for each component.

[0039] The lifting and adjusting assembly, according to the selected program, drives the ball screw to rotate via a servo motor, causing the slider to move up and down along the linear guide rail, thereby adjusting the position of the laser marking assembly to the optimal marking height. After receiving the instruction, the laser marking assembly emits a laser beam from the laser generator 6. After being focused by a high-precision optical lens group, the laser beam is accurately irradiated onto the workpiece at the marking station by the marking lens 7, completing the marking operation.

[0040] After the marking is completed, the code scanning assembly starts to work, which can judge whether the code marking is qualified or not. If it is qualified, the characteristic code is bound to the workpiece through the control assembly and uploaded to the cloud for data recording. The workpiece conveying assembly is started again to move the workpiece with completed marking from the marking station to the preparation station. The workpiece with completed marking is moved out by the taking-out device of the preparation station. At the same time, the workpiece conveying assembly receives the workpiece to be marked 13 provided by the mounting device of the preparation station and prepares to convey the next workpiece to be marked 13 to the marking station. If it is not qualified, the workpiece with completed marking can be moved from the marking station to the waste station by the workpiece conveying assembly. The workpiece with completed marking is moved out by the taking-out device of the waste station. Then, the lifting platform 9 of the workpiece conveying assembly moves to the preparation station. The workpiece conveying assembly receives the workpiece to be marked 13 provided by the mounting device of the preparation station and prepares to convey the next workpiece to be marked 13 to the marking station.

[0041] During the whole process, the components work cooperatively to realize automatic model changing and continuous production, which significantly improves the production efficiency.

[0042] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application. Any equivalent changes made on the structure, shape and principle of the present application should be covered within the protection scope of the present application.
