Description

Technical Field

[0001] The invention belongs to the technical field of laser engraving machines and relates to a full-automatic double-heating platform laser engraving machine. Background Art

[0002] In the field of modern industrial production, laser marking technology has been widely used due to its advantages such as high precision and permanent marking. However, the existing laser marking equipment mainly presents two common modes, each with its own characteristics and limitations.

[0003] One is the manual loading and unloading mode. In this mode, the operator needs to manually place the product on the heating platform. After the platform reaches a suitable temperature, the product is moved to the designated position for engraving. However, this mode has obvious disadvantages. From the perspective of production efficiency, there are many manual operation links, resulting in a low overall efficiency. In addition, when the temperature of the heating platform is high, the skills of the personnel responsible for loading the materials are quite high. The operator must not only be proficient in the timing of placing the product, but also accurately control the operating speed to avoid risks such as burns, which undoubtedly increases the labor cost and difficulty of operation.

[0004] The second is to achieve fully automatic processing by adding jigs. This mode uses jigs to flatten the product and uses clip loading and unloading to achieve fully automatic operation. However, this mode also faces many problems. On the one hand, the process of putting products in and out of jigs is added, and the positioning accuracy requirements between products and jigs are extremely strict, which greatly increases production costs. On the other hand, due to the stress of the product itself, it is difficult for the jig to completely flatten it, resulting in poor product flatness during subsequent laser engraving, which ultimately results in low overall processing accuracy and a decrease in yield rate. In addition, this mode can only process products with fixed sizes and relatively complete appearances, and cannot effectively process defective products.

[0005] In summary, both existing laser engraving machine equipment models have certain shortcomings in practical applications and need to be further improved and perfected to better meet the diverse industrial production needs. Summary of the invention

The visual camera will visually locate and shoot the marked product and transmit the photographed product information to the backend server to determine whether the marked product is qualified; After step 7 and step 6 are completed, the conveying component drives the heating component to move to the initial position, and the grabbing component grabs the engraved product and places it on the empty tray of the corresponding receiving platform according to whether the product is qualified by the background server; Step 8: Repeat the operation in step 2, and repeat this cycle until there is no tray on the upper plate platform.

DETAILED DESCRIPTION

[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0026] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention. Example

[0027] See also Figure 1 As shown, a fully automatic dual-heating platform laser marking machine includes a frame 1, a workbench 11 is arranged on the frame 1, and a laser marking device 2 is arranged on the frame 1, and the laser marking device 2 has a laser marking area. It is worth mentioning that there are two sets of conveying devices on the workbench 11, which are used for loading, feeding and receiving products. The above two sets of conveying devices have the same structure and are distributed on both sides of the laser marking device 2 in a mirror-symmetrical manner. When in use, the two sets of conveying devices can alternately convey the product to the laser marking area, and the laser marking device 2 performs laser marking on the product, and the overall efficiency is high.

[0028] The conveying device of the present invention is a fully functional and highly efficient system, which includes an upper plate assembly 3, a material grabbing assembly 4, a heating assembly 5, a conveying assembly 6, a visual assembly 7 and a lower plate assembly 8, wherein: the heating assembly 5 can move back and forth on the predetermined track of the conveying assembly 6, and this feature provides a strong guarantee for the smooth progress of the entire engraving process. The operation steps are as follows: Step 1: First, the pallets with products should be stacked in order on the upper plate platform 31 of the upper plate assembly 3. Once the placement is completed, the equipment will automatically position the pallets on the upper plate platform 31 in an orderly manner to ensure that each pallet is in the correct position, laying a good foundation for subsequent operations; Step 2: The upper plate platform 31 will move upward until the uppermost tray reaches the designated position and stops. At this time, the suction nozzle on the material grabbing component 4 will work to firmly absorb the product in the uppermost tray and accurately move it to the heating platform of the heating component 5 to prepare for the next step of heating treatment; Step 3, the heating component 5 starts heating the product, and its goal is to make the temperature of the product within the set temperature range. When the temperature reaches the predetermined temperature value, the heating component 5 will move along the predetermined track. At the same time, the material grabbing component 4 will absorb the empty tray at the top of the upper plate platform 31 and accurately move it to the plate receiving platform of the lower plate component 8. Then, the upper plate platform 31 moves upward again, repeating the previous action, so that the uppermost tray moves to the specified position again and stops; Step 4: The visual component 7 is set on one side of the track where the heating component 5 moves. When the heating component 5 moves to the sensing area of ​​the visual component 7, the visual camera on the visual component 7 is immediately started to visually locate the product on the heating component 5 and transmit the obtained product position information to the background server. After completing the positioning, the heating platform 5 will move forward to the laser engraving area and wait for the laser engraving to start; Step 5: After receiving the product location information from the visual component 7, the backend server processes the uploaded product information and obtains accurate product location information, and transmits the processing result to the laser marking device 2. The laser marking device 2 performs precise laser marking operations on the product in the laser marking area according to the received instructions to ensure the quality and accuracy of the marking; Step 6: When the laser marking is completed, the heating component 5 will move back and re-enter the sensing area of ​​the visual component 7. At this time, the visual camera will start again to visually locate and shoot the marked product, fully capture the information of the product after marking, and transmit the photographed product information to the background server to accurately judge whether the marked product is qualified; Step 7: After the visual sensing is completed, the heating component 5 continues to move back until it returns to the initial position. The material grabbing component 4 will absorb the engraved products according to the previously determined results of whether the products are qualified, and place them on the empty trays of the receiving platform of the lower plate component 8, so as to effectively distinguish qualified products from unqualified products, which is convenient for subsequent processing and statistics; Step 8, repeat the operation of step 2, and repeat this cycle until there is no tray on the upper plate platform 31, and the entire fully automatic double heating platform laser marking machine has completed a complete round of product laser marking and sorting process.

[0029] Specifically, if Figure 2As shown, the upper plate assembly 3 of the present invention is mainly composed of multiple parts. The first is the upper plate bracket, which serves as the support frame of the entire upper plate assembly and provides a stable installation foundation for other components. A baffle 33 is set at the diagonal of one side of the upper plate bracket (the two baffles are distributed at 90 degrees). These two baffles will play a key role in the subsequent regular positioning process of the pallet. The upper plate platform 31 set on the upper plate bracket has two sides adjacent to the baffle 33, which is the main area for placing pallets.

[0030] The upper plate platform 31 is provided with a material pushing assembly, which includes slide grooves 311 staggered on the upper plate platform, each baffle plate corresponds to at least one slide groove, and these slide grooves 311 are vertically distributed with the corresponding baffle plate. More importantly, a baffle rod 32 is vertically arranged in each slide groove 311, and at the same time, the upper plate bracket is equipped with a first driving mechanism that drives the baffle rod 32 to move along the slide groove 311. This first driving mechanism has a variety of optional forms, including but not limited to a cylinder, a motor-driven screw module, etc. When the tray is placed on the upper plate platform 31, the first driving mechanism will drive the baffle rod 32 to move in the slide groove 311, and the baffle rod 32 will forcefully push the tray to move toward the side of the baffle plate 33 until both sides of the tray are firmly against the baffle plate. In this way, the regular positioning of the tray can be completed accurately and efficiently, ensuring that each tray is in an accurate position, providing a good prerequisite for subsequent loading and other operations.

[0031] In order to improve the overall appearance of the device and protect the internal components, a protective cover 34 is provided on the periphery of the upper plate bracket. This protective cover 34 properly shields the upper plate bracket and the drive mechanism, making the entire device look neater and more beautiful in appearance, and can also prevent dust and other impurities from entering the interior to a certain extent, affecting the normal operation of the components.

[0032] A second driving mechanism 35 is provided on the frame 1 below the upper plate support. The second driving mechanism 35 is mainly composed of a screw module driven by a servo motor, and a guide column is provided on the periphery of the screw module. These screw modules and guide columns are closely connected to the upper plate platform 31, and they cooperate with each other to guide the upper plate platform 31 to move up and down stably. This stable up and down movement is very important for accurately delivering the tray to the appropriate position so that the material grabbing assembly can grab the product.

[0033] In addition, a first sensor 36 is provided on the baffle 33, which is responsible for sensing the pallet. When the first sensor 36 senses the pallet, it will promptly send a signal to the control system to stop the second drive mechanism 35, thereby ensuring that the upper plate platform 31 is in a suitable position. Of course, there is another situation that needs to be considered, that is, when the screw module driven by the servo motor reaches the set stroke, but the first sensor 36 does not sense the pallet at this time, this means that there is no pallet on the upper plate platform 31, and this information will also be accurately fed back to the control system so that the equipment can make corresponding subsequent operation arrangements.

[0034] In the fully automatic dual-heating platform laser engraving machine of the present invention, the material grabbing component 4 is mainly composed of a three-axis mobile platform that can move in the X-axis, Y-axis, and Z-axis directions. This platform has precise movement capabilities and can flexibly adjust the position. A nozzle mounting plate is arranged on the three-axis mobile platform. With the help of the three-axis mobile platform, the nozzle mounting plate can move freely along the X-axis, Y-axis, and Z-axis directions, thereby realizing multi-directional positioning.

[0035] Several suction nozzles are installed under the suction nozzle mounting plate. These suction nozzles are important components for realizing the action of grabbing and releasing materials. They are connected to the external vacuum system through a hose. When the vacuum system starts working, the suction nozzle can generate suction, thereby firmly adsorbing the product or tray for subsequent moving operations. When it is necessary to release the material, the suction can be easily released by controlling the vacuum system to complete the release action, ensuring that the entire process of loading and receiving materials can be carried out efficiently and accurately.

[0036] In the fully automatic dual-heating platform laser marking machine of the present invention, the heating component 5 is a key part to ensure the marking quality of the product.

[0037] like Figure 3 As shown, the heating assembly 5 is mainly composed of a heating shell 51, a heating platform 52 and a positioning block 53. The upper end surface of the heating shell 51 is provided with an exposed heating platform 52, which is an important area for placing products and heating them. The bottom of the heating shell 51 is a positioning block 53 fixed on the conveying assembly 6. The positioning block 53 can ensure the accurate installation and stable positioning of the heating assembly 5 on the conveying assembly 6, so that it can maintain a precise track during the back and forth movement.

[0038] A heater with a temperature control function is provided in the heating housing 51. This heater can accurately control the temperature of the heating platform 52 to reach and maintain it within a set temperature range, thereby providing a suitable heating environment for the product, ensuring that the product can achieve an ideal engraving effect in subsequent laser engraving operations, and effectively improving the accuracy and quality of engraving.

[0039] The heating component 5 in this application is fully involved in the entire process of loading and processing, and keeps the product in a suitable temperature state during processing, thereby greatly improving the processing efficiency and quality of the product. At present, some products need to have a certain temperature during processing. The existing conventional means is to preheat the product outside the production line, and then manually place it in the laser engraving equipment for laser engraving, and its temperature cannot be accurately controlled. This application document uses a heating component as a mobile carrier for the product, which can solve this technical problem well, keep the product in a suitable temperature range, and also reduce labor intensity.

[0040] In the fully automatic dual-heating platform laser engraving machine of the present invention, the conveying assembly 6 mainly includes a conveying bracket installed on the workbench 11, which provides a stable support foundation for the entire conveying structure. A screw module driven by a servo motor is arranged on the conveying bracket, and this driving method can ensure accurate and stable power output. The positioning block 53 of the heating assembly 5 is cleverly installed on the nut of the screw module through a connector, so that when the screw module is driven by the servo motor, it can drive the heating assembly 5 to move accurately along the predetermined track.

[0041] In addition, sensors are carefully set at key positions of the conveying component 6, including its initial position, the laser marking area, and the sensing area of ​​the visual component 7. These sensors can sense the position status of the heating component 5 in real time and feed back relevant information to the control system in a timely manner, thereby achieving precise control of the entire conveying and marking process, ensuring that each link is carried out in an orderly and efficient manner, and ensuring the stable operation and precise marking of the laser marking machine.

[0042] In the fully automatic dual-heating platform laser engraving machine of the present invention, the visual component 7 includes a visual bracket installed on the workbench 11, and the visual bracket provides a stable installation foundation for subsequent components. A visual camera is installed on the visual bracket.

[0043] When the pallet with products passes through the area where the visual component 7 is located under the drive of the conveyor component, the visual camera will start working quickly. It can carefully visually locate the products on the pallet with extremely high clarity and accuracy, and accurately capture key information such as the position and posture of the products. Subsequently, the acquired information will be transmitted to the background server in a timely manner, providing indispensable data support for subsequent laser marking equipment to perform precise marking and quality judgment of the marked products, thereby effectively ensuring the accuracy and efficiency of the entire laser marking process.

[0044] In the fully automatic dual-heating platform laser engraving machine of the present invention, the lower plate assembly 8 is also an indispensable and important part. The lower plate assembly 8 includes at least two sets of plate receiving platforms, which undertake the important task of receiving and storing products and pallets in the operation process of the entire equipment. It is worth mentioning that the plate receiving platform has the vertical lifting function like the upper plate platform of the upper plate assembly 3. When the grabbing assembly 4 distinguishes the engraved products according to whether they are qualified or not and places them on the plate receiving platform, the plate receiving platform can be lifted and lowered in the vertical direction according to the actual storage situation, which improves the overall operation efficiency and space utilization of the equipment.

[0045] Compared with the existing technology, the fully automatic dual-heating platform laser engraving machine of the present invention has many significant advantages. In the existing technology, the manual loading and unloading mode is inefficient and requires high skills of personnel, and the fully automatic processing mode using jigs has many limitations. However, this equipment has achieved highly intelligent operation through a series of sophisticated designs. It can adapt to product processing in various situations, and the laser engraving process can be successfully completed in this equipment.

[0046] Moreover, this equipment has low requirements for feeding accuracy. Its unique upper plate component and material grabbing component work together to automatically complete operations such as regular positioning of pallets and product grabbing, without relying on high-precision feeding operations like traditional methods. More importantly, the entire processing process does not require human intervention. From product feeding, heating, visual positioning to laser engraving and the final collection and separation, a series of links can be automatically completed by the close cooperation between the various components of the equipment itself, which greatly improves production efficiency and product quality stability.

[0047] Of course, the fully automatic dual-heating platform laser marking machine of the present invention, like a conventional laser marking machine, also has components such as a power supply unit and a control unit to achieve normal movement of the laser marking machine.

[0048] Obviously, the above-described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
