Description

Technical Field

[0001] This utility model is an adsorption stage, relating to the field of laser engraving technology. Background Technology

[0002] Laser engraving is a physical transformation that involves the instantaneous melting and vaporization of materials under laser irradiation to achieve the desired processing purpose.

[0003] When laser engraving a workpiece, it is necessary to limit and fix the workpiece so that the laser can engrave the workpiece and prevent the workpiece from shaking or shifting during the laser engraving process. This will prevent the workpiece from being damaged or failing to meet quality standards due to laser engraving deviation.

[0004] When fixing and limiting workpieces, referring to patent document CN215546990U, the device proposed in this patent document uses an air groove to export vacuum into a recess. The recess is used to adsorb the parts to be processed. A density plate is set in the recess, with many sparse air holes distributed inside. The vacuum exported from the air groove is evenly distributed on the surface of the density plate, which effectively increases the adsorption area of ​​the parts and improves the adsorption effect. In the actual application of adsorbing workpieces, although this device can adsorb workpieces and the adsorption effect is good, different recess shapes are required according to the shape of the workpiece. The operator needs to change the adsorption component according to the shape of the workpiece, which is relatively cumbersome. The effect of use needs to be improved. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an adsorption stage to solve the problems mentioned in the background art. This utility model can adjust the adsorption according to the different shapes of workpieces, thereby greatly improving the use effect of laser engraving of workpieces and greatly improving the applicability and practicality of the device.

[0006] To achieve the above objectives, this utility model employs the following technical solution: It includes a motherboard, the bottom of which is provided with an adjustment mechanism. The adjustment mechanism includes two mounting frames fixedly connected to the bottom surface of the motherboard. Two positive and negative threaded rods are rotatably connected to one side of the two mounting frames that are close to each other. Two servo motors are fixedly connected to the outer surface of one mounting frame, and the output ends of the servo motors rotatably pass through the mounting frame on the same side and are fixedly connected to the positive and negative threaded rods. Threaded rings are threaded onto the positive and negative threaded surfaces of the two positive and negative threaded rods, and an adjustment plate is fixedly connected to one side of the two threaded rings that are close to each other. Dual-output shaft motors are fixedly connected to the upper surfaces of the two adjustment plates, and threaded rods are fixedly connected to the two output shafts of the dual-output shaft motors. An adjustment block is threadedly connected to the outer surface of each threaded rod.

[0007] Furthermore, support legs are fixedly connected to the four corners of the bottom surface of the motherboard, and foot pads are fixedly connected to the lower end of the support legs. By setting support legs, the overall device can be better supported and moved, thereby avoiding the shaking of the overall device when adsorbing the workpiece and affecting the laser engraving effect on the workpiece. In addition, the setting of foot pads can greatly improve the stability of the overall device and increase the friction between the device and the ground.

[0008] Furthermore, both of the outer surfaces of the two positive and negative threaded rods are fixedly connected with blocking rings, and the blocking rings are located at the center of the positive and negative threaded rods. By setting the blocking rings, the threaded rings on both sides can be better limited and blocked, avoiding the risk of the threaded rings shifting and getting stuck when they move laterally on the surface of the positive and negative threaded rods, and greatly improving the safety of the device during use.

[0009] Furthermore, each of the threaded rods is rotatably connected to a blocking block at the end away from the dual output shaft motor, and the bottom surface of the blocking block is fixedly connected to the upper surface of the adjusting plate. By setting the blocking block, it is easy to limit and block the adjusting block, and improve the stability of the threaded rod when rotating, avoiding the risk of shaking and tilting when the threaded rod drives the adjusting block to move laterally.

[0010] Furthermore, the upper surface of the motherboard is provided with adsorption vent holes, and the vent pipe is located at the center above the adjustment mechanism. By providing adsorption vent holes, it is convenient to adsorb the workpiece located on the adsorption vent holes through subsequent components, thereby facilitating laser engraving of the workpiece.

[0011] Furthermore, each of the pre-drilled holes on the upper surface of the adjustment block is fitted with a vent pipe, and the upper end of the vent pipe is fixedly connected to a sealing ring. Each sealing ring is tightly fitted to the bottom surface of the main board. By setting the vent pipe, it can be connected to the air extraction device, thereby adsorbing the workpiece through the tight fit between the adsorption vent hole and the sealing ring, preventing the workpiece from shaking during laser engraving. In addition, a sealing gasket is provided at the connection surface between the sealing ring and the adsorption vent hole, which greatly improves the sealing performance between the sealing ring and the adsorption vent hole.

[0012] Furthermore, each of the vent pipes is fitted with a telescopic spring on its outer surface, and the telescopic spring is located between the sealing ring and the adjusting block on the side that are close to each other. By setting the telescopic spring, it is easy to lift the sealing ring, so that the sealing ring and the adsorption vent can be squeezed and sealed, which can further improve the sealing performance between the sealing ring and the adsorption vent.

[0013] Furthermore, the upper surfaces of both adjustment plates are fixedly connected with slide bars, and the outer surface of the slide bars is slidably connected to the sliding groove on the bottom surface of the adjustment block. By setting slide bars, the stability of the adjustment block during lateral movement can be improved, and the displacement of the adjustment block during lateral movement can be avoided, thus affecting the suction effect.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model incorporates a servo motor. The output shaft of the servo motor drives the positive and negative threaded rods to rotate, thereby causing the positive and negative threaded rods to drive two servo motors to move laterally. This, in turn, drives the adjustment plate to move laterally, achieving lateral adjustment of the adsorption device. After lateral adjustment, the dual output shaft motor can be activated. Both output shafts of the dual output shaft motor drive the threaded rods to rotate, causing the threaded rods to drive the adjustment block to move laterally. This allows the adjustment block to adjust the adsorption component, facilitating the adjustment of the adsorption area according to workpieces of different sizes. This allows for adsorption of the four corners of the workpiece's bottom surface, preventing the workpiece from shaking or shifting during laser engraving, significantly improving the applicability and practicality of the device.

[0016] 2. This utility model, by setting support legs, can better support and move the overall device. By setting blocking rings, it can better limit and block the threaded rings on both sides, avoiding the risk of the threaded rings shifting and getting stuck when moving laterally on the surface of the positive and negative threaded rods. By setting adsorption vent holes, it is easy to adsorb the workpiece located on the adsorption vent holes through subsequent components. By setting vent pipes, it can be connected to the air extraction device, so that the workpiece can be adsorbed through the tight fit between the adsorption vent holes and the sealing ring. By setting telescopic springs, it is easy to lift the sealing ring, so that the sealing ring and the adsorption vent holes can be squeezed and sealed. By setting slide bars, it is easy to improve the stability of the adjusting block when moving laterally. Attached Figure Description

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] See Figures 1-4 This embodiment proposes an adsorption stage, including a main board 1. The bottom of the main board 1 is provided with an adjustment mechanism 2. The adjustment mechanism 2 includes two mounting frames 201 fixedly connected to the bottom surface of the main board 1. Two positive and negative threaded rods 202 are rotatably connected to one side of the two mounting frames 201 that are close to each other. Two servo motors 203 are fixedly connected to the outer surface of one mounting frame 201, and the output end of the servo motor 203 rotatably passes through the mounting frame 201 on the same side and is fixedly connected to the positive and negative threaded rods 202.

[0025] refer to Figure 2 and Figure 4 The servo motor 203 is configured such that its output shaft drives the positive and negative threaded rod 202 to rotate, thereby causing the two servo motors 203 to move laterally, which in turn drives the adjustment plate 205 to move laterally. This enables the lateral adjustment of the adsorption device, allowing the adsorption area to be adjusted according to the size of the workpiece. This allows for the adsorption of workpieces of different sizes, facilitating laser engraving on the workpieces.

[0026] Support legs 3 are fixedly connected to the four corners of the bottom surface of the motherboard 1, and foot pads 4 are fixedly connected to the lower end of the support legs 3. By setting support legs 3 and foot pads 4, the stability of the overall device can be greatly improved, and the friction between the device and the ground can be increased.

[0027] Both positive and negative threaded rods 202 are fixedly connected to the outer surfaces of the two rods, and the blocking rings 5 ​​are located at the center of the positive and negative threaded rods 202. By setting the blocking rings 5, the threaded rings 204 on both sides can be better limited and blocked, avoiding the risk of the threaded rings 204 shifting and getting stuck when they move laterally on the surface of the positive and negative threaded rods 202. It can also avoid the risk of the threaded rings 204 being damaged when they shift during movement, thus greatly improving the safety of the device during use.

[0028] The upper surface of the main board 1 is provided with an adsorption vent 7, and the vent pipe 8 is located at the center above the adjustment mechanism 2. By setting the adsorption vent 7, it is easy to adsorb the workpiece located on the adsorption vent 7 through subsequent components, thereby facilitating laser engraving of the workpiece and greatly improving the adsorption work at different positions of the workpiece.

[0029] Both positive and negative threaded rods 202 are threaded with threaded rings 204 on their positive and negative threaded surfaces, and adjusting plates 205 are fixedly connected to the side of the two threaded rings 204 that are close to each other. A dual-output shaft motor 206 is fixedly connected to the upper surface of both adjusting plates 205, and threaded rods 207 are fixedly connected to the two output shafts of the dual-output shaft motor 206. Adjusting blocks 208 are threadedly connected to the outer surface of each threaded rod 207.

[0030] refer to Figure 2 and Figure 4 The dual-output shaft motor 206 is configured such that both output shafts of the dual-output shaft motor 206 drive the threaded rod 207 to rotate, causing the threaded rod 207 to drive the adjusting block 208 to move laterally. This allows the adjusting block 208 to adjust the adsorption component, making it easy to adjust the adsorption area according to different sizes of workpieces. This allows for adsorption of the four corners of the bottom surface of the workpiece, preventing the workpiece from shaking or shifting during laser engraving.

[0031] Each threaded rod 207 has a blocking block 6 rotatably connected to the end away from the dual output shaft motor 206, and the bottom surface of the blocking block 6 is fixedly connected to the upper surface of the adjusting plate 205. By setting the blocking block 6, the adjusting block 208 can be better blocked, thereby avoiding the risk of the threaded rod 207 falling off during the process of driving the adjusting block 208 to move laterally.

[0032] Each adjustment block 208 has a pre-drilled hole on its upper surface fitted with a vent pipe 8, and a sealing ring 9 is fixedly connected to the upper end of the vent pipe 8. Each sealing ring 9 is tightly fitted to the bottom surface of the main board 1. By setting the vent pipe 8, it can be connected to the air extraction device, so that the workpiece can be adsorbed by the tight fit between the adsorption vent hole 7 and the sealing ring 9, thus preventing the workpiece from shaking during laser engraving.

[0033] Each vent pipe 8 is fitted with a telescopic spring 10 on its outer surface. The telescopic spring 10 is located between the sealing ring 9 and the adjusting block 208 on the side that are close to each other. By setting the telescopic spring 10, it is easy to lift the sealing ring 9, so that the sealing ring 9 and the adsorption vent 7 are squeezed and sealed, which can further improve the sealing performance between the sealing ring 9 and the adsorption vent 7, and thus further improve the adsorption effect on the workpiece.

[0034] The upper surfaces of the two adjusting plates 205 are fixedly connected with slide bars 11, and the outer surface of the slide bars 11 is slidably connected to the sliding groove on the bottom surface of the adjusting block 208. By setting the slide bars 11, the stability of the adjusting block 208 during lateral movement can be improved, and the adjustment block 208 can be prevented from shifting during lateral movement, which would affect the suction adsorption effect, thus facilitating the subsequent adsorption of the workpiece.

[0035] Working principle: First, the entire device is moved to a predetermined position using the support legs 3 and foot pads 4. Then, the workpiece is placed above the main board 1, positioning it within the area of ​​the adsorption vent 7. Based on the size of the workpiece, the servo motor 203 is activated. The servo motor 203 drives the positive and negative threaded rods 202 to rotate, causing the threaded ring 204 to move laterally. During this movement, the threaded ring 204 also drives the adjusting plate 205 to move laterally, positioning the vent pipe 8 below the adsorption vent 7. The vent pipe 8 and the adsorption vent 7 are aligned... The device connects to the air intake and simultaneously activates the dual-output shaft motor 206. Both output shafts of the dual-output shaft motor 206 drive the threaded rod 207 to rotate, causing the threaded rod 207 to move the adjusting block 208 laterally. This allows for further adjustment of the position of the vent pipe 8. After adjustment, the device connects to the air extraction device via the vent pipe 8, and then uses the vent pipe 8 and the adsorption vent 7 to adsorb the bottom surface of the workpiece. This enables the adsorption of workpieces of different sizes and allows for adsorption of different areas on the bottom of the workpiece, significantly improving the applicability and practicality of the device.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
