Description

Technical Field

[0002] In the field of laser engraving technology, double-sided laser engraving equipment is an important device. It can perform high-precision and high-speed engraving operations on both surfaces of the workpiece. It is widely used in many industrial fields such as electronic products, automotive parts, medical devices and accessories.

[0003] However, traditional double-sided laser engraving equipment faces the problems of complex operation and low efficiency in the workpiece flipping process. This not only increases the frequency of manual intervention, but also easily leads to a decrease in positioning accuracy due to human errors, thus affecting the accuracy and consistency of the laser engraving effect.

[0004] In the actual production process, for workpieces with special shapes such as shells to be laser engraved, the existing fixed shells and other special shapes generally adopt the plug-in fixing method. During the flipping process, due to the design defects of the contact surface between the workpiece and the plug-in or insufficient friction, the workpiece is prone to slip. This phenomenon not only seriously damages the accuracy of laser engraving, but also may cause scratches or wear on the surface of the workpiece, directly reducing the overall quality of the product.

[0025] refer to Figure 1-6 An automated laser engraving device comprises an equipment body, the equipment body comprises a working turntable, a plurality of clamping devices are arranged on the working turntable, the working turntable can drive the clamping devices holding the workpieces to rotate, thereby realizing the movement of the workpieces in different workstations; a laser engraving device is arranged outside the working turntable for realizing laser engraving of the workpieces, a flipping device is arranged under the laser engraving device, and the flipping device can flip the workpiece on the clamping device; the working turntable, the clamping device and the laser engraving device are all existing technologies, and the specific structure will not be repeated here.

[0026] The flipping device includes a fixed frame 1, which is used to support the entire flipping device. The fixed frame 1 includes a base 11, a fixed plate 12 and a side plate 13. The base 11 is provided with a fixed plate 12, and two side plates 13 are symmetrically provided on the fixed plate 12. The side plates 13 are fixed on the base 11. The fixed plate 12 is provided with a lifting mechanism 2 to provide stable support for the lifting mechanism.

[0027] The lifting mechanism 2 includes a lifting drive 21, a slide rail 22, a lifting block 23 and a lifting plate 24. The lifting drive 21 can be a cylinder or a motor. The lifting drive 21 is arranged on the side of the fixed plate 12 away from the workpiece. Two slide rails 22 are symmetrically arranged on the side of the fixed plate 12 close to the workpiece. The lifting block 23 can slide on the slide rail 22, and a turning mechanism 3 is arranged on the two lifting blocks 23; a lifting groove 14 is arranged on the fixed plate 12, and a lifting plate 24 is arranged at the bottom of the lifting block 23. The lifting plate 24 passes through the lifting groove 14 and is connected to the output shaft of the lifting drive 21. The lifting plate 24 is driven by the lifting drive 21 to lift and lower, thereby driving the lifting block 23 to slide on the slide rail 22, thereby realizing the lifting and lowering of the turning mechanism 3.

[0028] The flipping mechanism 3 includes a transverse plate 31, a first wing plate 32, a second wing plate 33, a rotating shaft 34, a driven wheel 35, a driving wheel 36, a flip driving member 37 and a conveyor belt 38. The transverse plate 31 is fixedly connected to the lifting block 23. The two lifting blocks 23 can be symmetrically arranged on the transverse plate 31, which can improve the uniformity of the force on the transverse plate 31, thereby improving the stability of the lifting of the transverse plate 31; the first wing plate 32 and the second wing plate 33 are symmetrically arranged on the transverse plate 31, and the first wing plate 32 and the second wing plate 33 are provided with a rotating shaft 34 on the side close to the workpiece, and a fixing mechanism 4 is provided on the rotating shaft 34. The two ends of the rotating shaft 34 are respectively axially connected to the first wing plate 32 and the second wing plate 33, and the bearing axial connection can be used to reduce the friction force when the rotating shaft 34 rotates, thereby improving the smoothness of the rotating shaft 34 during rotation, and improving the sensitivity of the rotating shaft 34 during rotation, thereby improving the accuracy of the workpiece following the flipping mechanism 3 to flip, and improving the laser engraving effect of the workpiece.

[0029] One end of the rotating shaft 34 passes through the first wing plate 32 and is sleeved with a driven wheel 35. A driving wheel 36 is provided on the first wing plate 32. The driving wheel 36 is coaxially connected to the output shaft of the flip driving member 37. The flip driving member 37 can be a motor. A conveyor belt 38 is connected between the driving wheel 36 and the driven wheel 35. The driving wheel 36 is driven to rotate by the flip driving member 37, thereby driving the driven wheel 35 and the rotating shaft 34 to rotate through the conveyor belt 38, thereby realizing the flipping of the workpiece on the flipping mechanism 3. The outer surfaces of the driving wheel 36 and the driven wheel 35 can be provided with multiple racks, which are distributed in a ring shape. The inner surface of the conveyor belt 38 is evenly distributed with multiple racks, so that the conveyor belt 38 is meshed with the driving wheel 36 and the driven wheel 35. This design can avoid the slippage between the driving wheel 36 and the driven wheel 35 and the conveyor belt 38 during the transmission process, thereby improving the stability of the driving wheel 36 and the driven wheel 35 during the transmission process. At the same time, through the meshing between the racks, the rotation accuracy of the driving wheel 36 and the driven wheel 35 during the transmission process can be improved, thereby improving the rotation accuracy of the workpiece. The conveyor belt 38 is also covered with a rubber belt, which can be used to constrain the conveyor belt 38, so that the conveyor belt 38 is always closely fitted with the driving wheel 36 and the driven wheel 35 during the transmission process, ensuring the transmission effect and transmission sensitivity.

[0030] The fixing mechanism 4 includes a plurality of connectors 41, which are evenly distributed on the flipping mechanism 3. A fixing platform may be provided between the plurality of connectors 41 and the rotating shaft 34, which may increase the connection area between the connector 41 and the rotating shaft 34, thereby improving the connection strength between the connector 41 and the rotating shaft 34. An air pipe joint is also provided on the rotating shaft 34, which is connected to the pneumatic device. The connector 41 is plugged and matched with the workpiece to achieve the fixation of the workpiece on the connector 41. A plurality of adsorption chambers may be formed between the connector 41 and the workpiece. Under the action of the starting device, the plurality of adsorption chambers between the connector 41 and the workpiece may be in a negative pressure or vacuum state, thereby firmly fixing the workpiece on the connector 41, achieving a stable clamping of the workpiece and maintaining its position during the flipping process. The fixing strength between the connector 41 and the workpiece may be enhanced, thereby improving the stability of the workpiece being fixed on the connector 41, avoiding slippage during the flipping process of the workpiece, and realizing quick plugging and separation between the workpiece and the connector 41, thereby improving production efficiency.

[0031] Embodiment 1: The connector 41 includes a connector body 411 disposed on the flipping mechanism 3. The connector body 411 rotates with the flipping mechanism 3 to achieve flipping of the workpiece. The connector body 411 is plugged into and matched with the workpiece to form a pre-positioning when the workpiece is fixed on the connector 41. The cross-section of the connector body 411 can be elliptical and can be set according to the shape of the blind hole of the workpiece to make it compatible with the blind hole of the workpiece, thereby having a better fixing effect. The outer cover of the plug-in body 411 is provided with an elastic anti-skid layer, which can be made of rubber material. The rubber has sufficient elastic deformation, which can meet the elasticity and friction requirements when the plug-in body 411 and the workpiece are plugged in, so that the plug-in body 411 and the workpiece form a transition fit, which is convenient for the plug-in and separation of the plug-in body 411 and the workpiece; the periphery of the end face of the elastic anti-skid layer is rounded, so that the workpiece has a guiding effect when plugged into the plug-in body 411, which is convenient for the plug-in of the workpiece on the plug-in body 411; when the plug-in body 411 and the workpiece are plugged in, the elastic anti-skid layer can be deformed under the extrusion of the inner wall of the workpiece, increasing the contact area between the plug-in body 411 and the workpiece, thereby enhancing the connection fixation between the two; the overall thickness of the elastic anti-skid layer and the plug-in body 411 can be larger than the inner wall size of the workpiece, and when the inner wall size of the workpiece is at the maximum processing error, the elastic anti-skid layer can still be over-fit with the workpiece, meeting the fixing strength and stability requirements of the workpiece on the connector 41.

[0032] An air extraction hole 412 is formed through the plug body 411 , and the air extraction hole 412 is connected to a pneumatic device for extracting and delivering air at the air extraction hole 412 .

[0033] At least two annular grooves 413 are provided on the plug-in body 411. The annular grooves 413 can be set according to the size of the workpiece to meet the fixing strength and stability of the workpiece on the plug-in body 411. A plurality of connecting holes 414 are provided in the annular groove 413. The connecting holes 414 are connected to the air extraction holes 412. A first adsorption chamber is formed between the annular groove 413 and the side wall of the workpiece. Since a relatively sealed structure is formed between the two ends of the annular groove 413 and the side wall of the workpiece, the air extraction device extracts air and extracts the air in the first adsorption chamber through the connecting holes 414 and the air extraction holes 412, so that the first adsorption chamber is in a negative pressure or vacuum state, and multiple fixing structures are formed between the side wall of the workpiece and the plug-in body 411, namely, the friction between the side wall of the workpiece and the elastic anti-slip layer, and the extrusion force of the atmospheric pressure on the side wall of the workpiece at the first adsorption chamber, thereby enhancing the connection strength and stability between the workpiece and the plug-in body 411.

[0034] The design of multiple annular grooves 413 can reduce the overall structural strength of the elastic anti-skid layer on the plug-in body 411, so that when the plug-in body 411 is plugged into the workpiece, the elastic anti-skid layer is easy to deform, which facilitates the plug-in of the workpiece and the plug-in body 411, thereby improving the plug-in speed.

[0035] A ball groove 415 is provided at one end of the plug-in body 411 that abuts against the workpiece, and a second adsorption chamber is formed between the ball groove 415 and the inner wall of the workpiece; a sealing ring 416 is provided at the end of the plug-in body 411 away from the workpiece, and the sealing ring 416 can achieve sealing between the workpiece and the plug-in body 411, and the vacuum device draws air to extract the air in the second adsorption chamber through the ball groove 415 and the vacuum hole 412, so that the second adsorption chamber is in a negative pressure or vacuum state, and the atmospheric pressure at the second adsorption chamber is lower than the normal atmospheric pressure value. The air outside the workpiece generates an extrusion force on the workpiece at the second adsorption chamber, so that the workpiece is fixed on the plug-in body 411; and cooperates with the first adsorption chamber and the sealing ring 416 to form a multiple fixing structure between the workpiece and the plug-in body 411, thereby enhancing the connection strength and stability between the workpiece and the plug-in body 411.

[0036] To further illustrate the content of the invention of the present application, more specifically, in a specific implementation, when the plug-in body 411 is inserted into the interior of the workpiece, one or more closed or semi-closed spaces are formed between the annular groove 413 thereon and the side wall of the workpiece, namely, the first adsorption chamber. The air in the first adsorption chamber is evacuated by the pneumatic device to the air extraction hole 412, so that a negative pressure or near-vacuum state is formed in the chamber. Under the negative pressure state, the external atmospheric pressure is higher than the air pressure in the first adsorption chamber, so the atmospheric pressure will produce an inward squeezing force on the side wall of the workpiece, so that the workpiece is firmly pressed on the plug-in body 411. Correspondingly, a second adsorption chamber is formed between the ball groove 415 at the end of the plug-in body 411 and the inner wall of the workpiece. Similarly, when the pneumatic device evacuates the air extraction hole 412, the air in the second adsorption chamber is also evacuated to form a negative pressure. The external atmospheric pressure acts on the inner wall of the workpiece, generating an inward squeezing force, which further strengthens the connection between the workpiece and the plug-in body 411. Moreover, in this embodiment, a sealing ring 416 is designed at the top of the plug-in body 411. When the plug-in body is fully inserted into the workpiece, the sealing ring 416 fits tightly against the mouth of the workpiece to form a seal. The sealing ring 416 not only prevents the destruction of the negative pressure state in the first and second adsorption chambers, but also further ensures the stability of the negative pressure environment through its sealing effect. At the same time, an elastic anti-skid layer, such as a rubber layer, is provided on the outside of the plug-in body 411. During the plug-in process, the elastic anti-skid layer is squeezed by the inner wall of the workpiece and deformed, thereby increasing the contact area and friction with the inner wall of the workpiece. The above-mentioned friction force and the negative pressure of the first and second adsorption chambers complement each other and jointly improve the stability of the connection.

[0037] It can also be seen from the matching relationship and function of the above structure that the extrusion force generated by the negative pressure in the first adsorption chamber and the second adsorption chamber, together with the friction force provided by the elastic anti-skid layer, forms a multi-directional and balanced fixed force field (superposition of multiple forces), which can constrain the workpiece from multiple directions, making it difficult for the workpiece to slip or dislocate during the flipping process. The presence of the sealing ring 416 ensures the stability of the negative pressure environment in the first and second adsorption chambers, and prevents the weakening of the fixing force due to air leakage. A continuous and uniform extrusion force can be maintained in a stable negative pressure environment to ensure the position accuracy of the workpiece during the flipping process; in addition, the design of the elastic anti-skid layer enables the plug-in body 411 to adapt to workpiece blind holes of different sizes and shapes, increasing the versatility and fault tolerance of the equipment. Even if there are certain manufacturing errors in the workpiece size, the elastic anti-skid layer can compensate for these errors through deformation to ensure that the workpiece can be firmly fixed on the plug-in body.

[0038] In summary, the multiple fixing structures composed of the first adsorption chamber, the second adsorption chamber, the sealing ring 416 and the elastic anti-slip layer significantly enhance the connection strength and stability between the workpiece and the plug-in body 411, providing a strong guarantee for the precise flipping of the workpiece and high-quality laser engraving.

[0039] In some embodiments, the sealing ring 416 may be a frustum ring, whose diameter gradually decreases from one end to the other end. When the sealing ring 416 is plugged into the workpiece, the sealing ring 416 has a guiding effect on the workpiece, so that the workpiece can smoothly enter the interior of the sealing ring, reducing the impact and damage caused by direct impact. The inclined surface of the frustum ring can gradually compress the gap between the workpiece and the sealing ring during the plugging process, thereby achieving the sealing of the workpiece by the sealing ring 416, which helps to form a preliminary sealing effect in advance, and then facilitates the transition between the negative pressure or vacuum state and the normal pressure state between the workpiece and the plug body 411. The sealing ring 416 can be a rubber ring, because rubber has good elasticity and sealing performance, and can deform when subjected to pressure, filling the small gap between the workpiece and the plug body, thereby achieving effective sealing. In addition, the softness of the rubber can also reduce the friction and wear between the workpiece and the sealing ring, thereby extending the service life of the equipment. The sealing ring 416 is provided with a plurality of convex rings that are continuously increasing in size. These convex rings will successively contact the inner wall of the workpiece during the insertion process of the workpiece to form a multi-stage seal, which can increase the contact area between the workpiece and the sealing ring 416 when the workpiece is plugged in. As the workpiece continues to go deeper, each stage of the convex ring will have a closer contact with the inner wall of the workpiece after the multi-stage superposition, thereby gradually increasing the contact area to form a multi-stage seal, and the overall sealing effect is significantly improved. The above-mentioned structural design can significantly improve the sealing effect between the sealing ring and the workpiece, prevent gas or liquid leakage, and thereby enhance the sealing effect of the sealing ring 416 on the workpiece.

[0040] In summary, through the design of the frustum ring shape, rubber material and multiple increasing convex rings, the sealing ring 416 can significantly increase the contact area with the workpiece when plugged in, and enhance the sealing effect on the workpiece. This is particularly important in automated laser engraving equipment, which can ensure that the workpiece works stably under negative pressure or vacuum conditions and improve the overall performance and reliability of the equipment.

[0041] In some embodiments, limit members 7 are symmetrically provided at both ends of the fixed plate 12, and the limit members 7 include limit blocks 71. The limit blocks 71 are fixed on the end surface of the fixed plate 12, and limit rods 72 are provided on the limit blocks 71. A cross plate 31 is provided above the limit rods 72. The limit rods 72 can limit the descending height of the cross plate 31, thereby limiting the descending height of the connector 41, thereby preventing the connector 41 from descending too much and causing damage to the workpiece when the connector 41 is connected with the workpiece.

[0042] In some embodiments, a measuring mechanism 6 is provided on the flipping mechanism 3, and the measuring mechanism 6 includes a measuring instrument 61 and a turntable 62. The measuring instrument 61 can be a goniometer. The measuring instrument 61 is fixed to the end of the second wing plate 33 away from the first wing plate 32, and the turntable 62 is sleeved on the end of the rotating shaft 34 that passes through the second wing plate 33. The measuring instrument 61 can measure the rotation angle of the turntable 62, thereby realizing the measurement of the rotation angle of the rotating shaft 34, and then realizing real-time monitoring of the rotation angle of the workpiece, so as to realize the precise rotation of the workpiece and ensure the laser engraving effect of the workpiece; and when an abnormal situation occurs, timely feedback can be given to handle the abnormal situation, thereby reducing defective products and improving maintenance efficiency.

[0043] The specific working principle is as follows: The robot grabs the workpiece from the assembly line and fixes it on the clamping device. The clamping device loaded with the workpiece follows the rotation of the working turntable and enters the laser engraving area.

[0044] The lifting mechanism 2 is started, and the lifting drive 21 provides driving force to drive the lifting block 23 to move on the slide rail 22. Through the transmission of the cross plate 31 and the rotating shaft 34, the fixing mechanism 4 is lowered to an appropriate height, and the connector 41 is made to correspond one to one with the workpiece. The lifting mechanism 2 continues to start, so that the connector 41 is further lowered, so that it is plugged into the workpiece, and the lifting drive 21 is paused.

[0045] Start the pneumatic device to perform the air suction action. At this time, the sealing ring 416 forms a sealing structure for the workpiece. At the same time, the elastic anti-skid layer makes the first adsorption chamber and the second adsorption chamber also form a relatively sealed structure. The air in the first adsorption chamber and the second adsorption chamber is extracted by the pneumatic device through the suction hole 412, so that the first adsorption chamber and the second adsorption chamber are in a negative pressure or vacuum state. The air pressure in the first adsorption chamber and the second adsorption chamber is lower than the air pressure of the external air. Under the action of the air pressure difference, the external air in the first adsorption chamber and the second adsorption chamber applies an extrusion pressure to the workpiece. At the same time, the friction between the elastic anti-skid layer and the inner wall of the workpiece is released, so that the workpiece is quickly fixed on the plug-in body 411.

[0046] The lifting drive member 21 restarts to provide driving force, driving the connector 41 with the workpiece fixed thereon to rise to a set height. The rising driving principle is similar to the descending driving principle and will not be described in detail here.

[0047] According to the processing surface of the workpiece to be laser engraved, a suitable rotation angle is set, and the flip driving member 37 is started, driving the active wheel 36 to rotate the set angle, and driving the driven wheel 35 to rotate through the conveyor belt 38, thereby driving the rotating shaft 34 to rotate, and then realizing the flipping of the workpiece at the set angle, so that the workpiece surface to be laser engraved is located below the laser engraving device. During the flipping process, the measuring mechanism 6 monitors the rotation angle of the turntable 62 in real time to ensure the flipping accuracy.

[0048] After the workpiece is flipped into place, the laser engraving equipment performs laser engraving on the surface to be processed. After the laser engraving is completed, if the next surface to be processed needs to be laser engraved, the workpiece is rotated to the next surface to be processed by the flip driving member 37 according to the above-mentioned rotation principle for laser engraving; the laser engraving operation is completed on all the surfaces to be processed of the workpiece.

[0049] After the laser engraving is completed, the flip driving member 37 is started, and the driving wheel 36, the driven wheel 35, and the conveyor belt 38 work together to rotate the rotating shaft 34 to the initial position, so that the workpiece faces downward and corresponds to the clamping device on the working turntable.

[0050] The lifting mechanism 2 is started, driving the workpiece to descend and fixing the workpiece on the clamping device.

[0051] Start the pneumatic device to perform the air supply action. The gas passes through the exhaust hole 412 and the connecting hole 414 and the ball groove 415 to enter the first adsorption chamber and the second adsorption chamber, so that the air pressure in the first adsorption chamber and the second adsorption chamber is equal to the external air pressure. At this time, the external air no longer applies a squeezing force to the workpiece. The workpiece is pushed by the gas in the first adsorption chamber and the second adsorption chamber, so that the workpiece moves away from the plug-in body 411, thereby realizing the rapid separation of the workpiece and the plug-in body.

[0052] The clamping device loaded with the laser engraved workpiece enters the unloading area under the rotation of the work turntable. The manipulator takes the workpiece out of the clamping device and places it on the assembly line to enter the next work process. At the same time, the firmware mechanism 4, the flip mechanism 3 and the lifting mechanism 2 all perform the reset operation to reset the entire flip device and wait for the next round of work; the entire laser engraving process of the workpiece is completed.

[0053] Embodiment 2: The difference from the first embodiment lies in the specific structure of the annular groove 413 on the plug body 411 .

[0054] Specifically, multiple annular grooves 413 can be arranged obliquely and interconnected to form a spiral groove (not shown in the figure) on the plug body 411. When the pneumatic device inhales air, due to the different distances between the annular grooves 413 at different positions and the pneumatic device, the suction strength at the connecting holes 414 of different annular grooves 413 is different. The connection of the annular grooves 413 enhances the suction strength of the top connecting hole 414. At the same time, when inhaling air, a spiral suction vortex is formed, so that the workpiece is subjected to the suction force in the opening direction of the connecting hole 414 and the ball groove 415, and is also subjected to the traction force of the spiral vortex, thereby enhancing the connection strength and stability of the workpiece on the plug body 411. When the pneumatic device delivers air, a spiral delivery vortex is also formed, so that the workpiece is subjected to the thrust in the opening direction of the connecting hole 414 and the ball groove 415, and is also subjected to the driving force of the spiral vortex, thereby further improving the separation speed of the workpiece and the plug body 411.

[0055] Embodiment 3: refer to Figure 6 The difference from the first embodiment lies in the structure between the sealing ring 416 and the annular groove 413 on the plug body 411 .

[0056] Specifically, a rolling groove 417 is provided at one end of the plug body 411 close to the sealing ring 416, and a rolling unit 5 is provided in the rolling groove 417. The rolling unit 5 includes a sleeve ring 51, which is arranged in the rolling groove 417 and can be welded and fixed to achieve the fixing of the sleeve ring 51 on the plug body 411. The sleeve ring 51 is provided with a plurality of rolling members 52, and the rolling members 52 can be balls embedded in the sleeve ring 51, and the balls protrude from the outer surface of the sleeve ring 51. The plurality of rolling members 52 roll with the inner wall of the workpiece. The rolling unit 5 can reduce the friction between the workpiece and the rear half of the plug body 411. When there is sufficient connection strength between the front half of the plug body 411 and the workpiece, it is convenient for the workpiece to be quickly and completely inserted into the plug body 411. At the same time, when the workpiece is separated from the plug body 411, the friction between the workpiece and the plug body 411 is reduced to achieve rapid separation.

[0057] The specific working principle is as follows: when the workpiece needs to be inserted into the plug-in body 411, the rolling element 52 (such as a ball) on the rolling unit 5 in the rolling groove 417 rolls with the inner wall of the workpiece with its rounded surface, effectively reducing the static friction resistance between the workpiece and the plug-in body 411. Compared with sliding contact, rolling contact can significantly reduce the driving force required during the insertion process, so that the workpiece can easily and quickly slide along the plug-in body 411 until it is fully in place. At the same time, the front half of the plug-in body 411 (the part that initially contacts the workpiece and bears the main connection force) is designed to have sufficient connection strength with the workpiece to ensure that the workpiece will not fall off or deflect due to external force during the insertion process, thereby achieving rapid and complete insertion of the workpiece. When the workpiece completes the laser engraving operation and needs to be separated from the plug-in body 411, at this time, during the reverse movement of the workpiece, the rolling element 52 continues to maintain rolling contact with the inner wall of the workpiece, effectively reducing the dynamic friction resistance during separation. This allows the workpiece to easily slide out of the plug-in body 411 without the need for additional separation force or complicated operating steps.

[0058] It should be noted that, although the rolling unit 5 reduces the friction during separation, the connection between the front half of the plug body 411 and the workpiece remains strong enough to ensure that the workpiece will not accidentally fall off due to misoperation or external factors during the separation process. Once the separation conditions are met, the workpiece can be separated quickly and smoothly.

[0059] In summary, the design of the rolling unit 5 not only facilitates the workpiece to be quickly and completely inserted into the plug-in body 411, thereby improving the operating efficiency; at the same time, when the workpiece is separated from the plug-in body 411, the separation force is also effectively reduced, thereby achieving rapid separation.
