Description

Technical Field

[0001] This utility model relates to the field of laser engraving mechanism technology, and in particular to a multi-station product rotary laser engraving mechanism. Background Technology

[0002] In industrial production, laser engraving technology, with its advantages of high precision, high efficiency, and non-contact operation, is widely used in the marking and pattern engraving processes of electronic, hardware, and plastic products. With the diversification and increasing complexity of products, many products require multi-faceted laser engraving, and the demands for laser engraving efficiency are also rising.

[0003] Currently, most traditional laser engraving equipment is designed for single-station operation, capable of engraving only a single surface of a product at a time. When processing multiple surfaces, manual adjustments to the product's position are required multiple times, which is not only cumbersome and labor-intensive but also inefficient, failing to meet the demands of mass production. Furthermore, some existing multi-station laser engraving equipment suffers from deficiencies in product positioning, rotational accuracy, and laser focal length adjustment, leading to inconsistent laser engraving quality and affecting product consistency and yield. In addition, the laser engraving process generates fumes and dust, which, if not handled promptly, can pollute the working environment and potentially affect laser transmission and processing accuracy.

[0004] Therefore, it is necessary to design a multi-station product rotary laser engraving mechanism to solve the above problems. Summary of the Invention

[0005] The purpose of this utility model is to provide a multi-station product rotary laser engraving mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: It includes a bottom frame, on which at least one set of product rotation mechanisms and at least one set of lifting laser engraving mechanisms are mounted; the product rotation mechanism includes a fixed base, on which a rotary motor is mounted, and the output shaft of the rotary motor is connected to a rotating fixture; the fixed base also has an adjusting fixed seat, on which an adjusting clamping cylinder is mounted, the output end of which is connected to a clamping connector, and a clamping rotation stop is mounted on the clamping connector; the lifting laser engraving mechanism includes a module fixing column, on which a module Z-axis is mounted, the module Z-axis is connected to a module Z-axis motor, and a laser is mounted on the module Z-axis; downstream of the laser's optical path are a coaxial reflector, a galvanometer, and a field lens in sequence; a camera and a lens are mounted on the coaxial reflector, the lens cooperating with the camera, and a light source is located below the coaxial reflector; a smoke exhaust vent is located next to the field lens.

[0007] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, its main features are:

[0008] This device, by incorporating multiple product rotation mechanisms and lifting laser engraving mechanisms, enables simultaneous laser engraving operations at multiple workstations, significantly improving production efficiency. The rotary motor in the product rotation mechanism drives the rotating jig and product to rotate, meeting the process requirements of multi-faceted laser engraving. Adjustable clamping cylinders, in conjunction with clamping rotating blocks, reliably clamp the product, preventing displacement during rotation and processing, thus ensuring processing accuracy. The Z-axis motor in the lifting laser engraving mechanism drives the module's Z-axis movement, precisely adjusting the height of the laser and related optical components to ensure a suitable laser focal length and improve engraving quality. A vision positioning system (camera, lens, and light source) accurately positions the product, further guaranteeing laser engraving accuracy. A fume vent promptly removes smoke and dust generated during laser engraving, ensuring a clean working environment and unobstructed laser path. Furthermore, the inclusion of a safety light curtain enhances the safety of equipment operation.

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0015] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0016] Please see Figures 1 to 3 This utility model embodiment provides a multi-station product rotary laser engraving mechanism, including a bottom frame 001. The bottom frame 001 serves as the basic support structure for the entire device, providing an installation platform for the various components above, and can also house electrical control systems, power transmission components, etc.

[0017] At least one set of product rotation mechanism 003 and at least one set of lifting laser engraving mechanism 002 are installed on the bottom frame 001. In this embodiment, it is preferred to set three sets of product rotation mechanism 003 and three sets of lifting laser engraving mechanism 002. The three sets of mechanisms correspond one to one, and three products can be laser engraved at the same time.

[0018] The product rotation mechanism 003 includes a fixed base 01, which is mounted on the working plane of the bottom frame 001 using bolts or other fasteners. A rotary motor 02 is mounted on the fixed base 01 and is directly fixed to it using bolts or other fasteners to ensure its stability during operation. The output shaft of the rotary motor 02 is directly connected to the rotary fixture 03, ensuring that rotational power is accurately and smoothly transmitted to the rotary fixture 03, enabling the rotary fixture 03 to drive the product in rotation.

[0019] The fixed base 01 is also equipped with an adjustable fixed seat 04, on which an adjustable clamping cylinder 06 is installed. The output end of the adjustable clamping cylinder 06 is connected to the clamping connector 07. The clamping force of the cylinder is transmitted to the clamping rotating stop 08 through the clamping connector 07. The clamping rotating stop 08 is installed on the clamping connector 07. When the rotating fixture 03 drives the product to rotate, the clamping rotating stop 08 can assist in limiting and clamping the product to prevent the product from deviating.

[0020] The product rotation mechanism 003 also includes an adjustment block 05. The adjustment block 05 is installed on the adjustment base 04 by means of a handle or other detachable connection. The position of the adjustment block 05 can be adjusted according to actual needs to adapt to the positioning requirements of products of different specifications.

[0021] The rotating mechanism 003 of the product is surrounded by a safety light curtain 09. The safety light curtain 09 is connected to the bottom frame 001 through a bracket and is used to detect whether personnel or foreign objects have entered the dangerous area, so as to ensure the safety of equipment operation and personnel operation.

[0022] The lifting laser engraving mechanism 002 includes a module fixing column 10, which is mounted on the bottom frame 001 to provide support for the entire lifting laser engraving mechanism 002. A module Z-axis 11 is mounted on the module fixing column 10. The module Z-axis 11 consists of linear guides and lead screws, and is connected to a module Z-axis motor 12. The module Z-axis motor 12 is connected to the module Z-axis 11 via a coupling. When the motor rotates, it transmits power to the module Z-axis 11, thereby driving other connected components to perform vertical lifting movements, achieving position adjustment of the laser engraving head in the Z-axis direction to achieve a suitable laser engraving focal length.

[0023] A laser 13 is mounted on the Z-axis 11 of the module. The laser 13 generates a laser beam, which is then transmitted through an optical path to a coaxial mirror 18, a galvanometer 14, and a field mirror 15. The coaxial mirror 18 changes the propagation direction of the laser beam, enabling it to travel along a specific path. These mirrors are connected by a precise optical mounting structure to ensure accurate laser beam transmission. After the galvanometer 14 changes the direction of the laser beam, it enters the field mirror 15, which focuses the laser beam onto the product surface, achieving precise laser engraving.

[0024] A camera 16 and a lens 17 are mounted on the coaxial reflector 18. The lens 17 is mounted on the camera 16, forming a vision positioning system used to acquire product image information, locate and inspect the product, and assist in the precise execution of laser engraving operations. A light source 19 is fixed below the coaxial reflector 18, close to the product's processing area, to provide suitable illumination for the camera 16 to acquire images, improving image clarity and contrast.

[0025] A smoke exhaust vent 20 is provided next to the field lens 15. The smoke exhaust vent 20 is connected to an external smoke purification device through a pipe. During the laser engraving process, the smoke and dust generated by the laser burning of the material are removed in time, ensuring the cleanliness of the working environment and the transparency of the laser beam path.

[0026] Working principle:

[0027] The product to be processed is placed on the rotating fixture 03. The position of the adjusting block 05 is adjusted according to the product specifications. The adjusting clamping cylinder 06 is activated, and the clamping rotating block 08 is driven by the clamping connector 07 to clamp and fix the product. The equipment is started, and the module Z-axis motor 12 drives the module Z-axis 11 to move. The height of the laser 13 and related optical components is adjusted so that the field lens 15 is at a suitable laser engraving focal length with the product surface. The light source 19 is lit, and the camera 16 and lens 17 acquire and position the product image, feeding the positioning information back to the control system. The control system controls the laser 13 to emit a laser beam. After being reflected by the coaxial reflector 18 and deflected by the galvanometer 14, the laser beam is focused onto the product surface by the field lens 15 for laser engraving.

[0028] During processing, if laser engraving is required on different surfaces of the product, the rotary motor 02 drives the rotary fixture 03 and the product to rotate to the corresponding angle, while the rotary stop block 08 is pressed to assist in limiting the position and ensure accurate product positioning. The fume extractor 20 continuously operates to remove fumes and dust generated during processing. The safety light curtain 09 monitors in real time; if personnel or foreign objects enter the danger zone, the equipment immediately stops operating to ensure safety.

[0029] Multiple sets of product rotation mechanisms 003 and lifting laser engraving mechanisms 002 work simultaneously to achieve synchronous processing at multiple workstations, greatly improving production efficiency.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the principles of the present utility model should be included within the protection scope of the present utility model.
