[0055] In some embodiments, two stop portions 12 are provided on the mounting seat 11 along the height direction, and part of the lifting bracket 20 is lifted and lowered between the two stop portions 12, further preventing the lifting bracket 20 from sliding out of the mounting bracket 10 from the upper or lower end, further improving the safety of the use of the driving device 100.

[0058] Please refer to Figure 3 In some embodiments of the present application, the lifting bracket 20 includes:

[0059] A back plate 21, the back plate 21 is arranged opposite to the mounting surface; and

[0060] The slider 22 connected to the back plate 21 is sleeved on the guide portion 13 and used to abut against the stop portion 12 . The elastic member 40 is sleeved on the guide portion 13 and located between the slider 22 and the stop portion 12 .

[0061] In this embodiment, the lifting bracket 20 includes a back plate 21 and a slider 22 arranged on the back plate 21, wherein the back plate 21 is arranged opposite to the mounting surface, and the plate surface of the back plate 21 can be used to install the processing head 200 of the processing equipment 1000, providing an installation space 221 and a stable support for the processing head 200. The processing head 200 is usually fixed on the side of the back plate 21 away from the mounting surface to facilitate the disassembly and maintenance of the processing head 200. Of course, the processing head 200 can also be fixed on the side of the back plate 21 facing the mounting surface to make the processing head 200 0 is located between the mounting surface and the back plate 21 to protect the processing head 200; the slider 22 is connected to the back plate 21, and can be convexly arranged on the side of the back plate 21 facing the mounting surface, or convexly arranged on the side of the back plate 21 away from the mounting surface, or arranged on the side of the back plate 21. The slider 22 is sleeved on the guide part 13 to make the lifting bracket 20 slidably connected to the guide part 13, and the elastic member 40 is sleeved on the guide part 13 and clamped between the stopper 12 and the slider 22, so as to buffer and support the lifting bracket 20.

[0062] The elastic member 40 is sleeved on the guide portion 13. In this way, the guide portion 13 is used as the installation position of the spring, which can limit the elastic member 40 and guide the expansion and contraction process of the elastic member 40 to prevent the elastic member 40 from falling off from between the stop portion 12 and the lifting bracket 20, and to prevent the elastic member 40 from deforming toward the outside of the stop portion 12 and the lifting bracket 20 when being squeezed, thereby improving the position and structural stability of the elastic member 40 in the driving device 100, and ensuring that the elastic member 40 can play a better and more stable elastic supporting role on the lifting bracket 20.

[0063] In some embodiments, two stoppers 12 are provided on the mounting bracket 10, which are respectively located above and below the slider 22. When the stopper 12 is located above the slider 22, it is used to limit the rising height of the lifting bracket 20, and when the stopper 12 is located below the slider 22, it is used to limit the descending height of the lifting bracket 20; the elastic member 40 can be arranged between the upper stopper 12 and the sliding member, and the two ends of the elastic member 40 can be respectively connected to the stopper 12 and the slider 22. When the lifting bracket 20 descends, the elastic member 40 is stretched, and when the lifting bracket 20 rises, the elastic member 40 is compressed; the elastic member 40 can also be arranged between the lower stopper and the slider 22. At this time, when the lifting bracket 20 descends, the elastic member 40 is compressed, and when the lifting bracket 20 rises, the elastic member 40 is stretched. Of course, elastic members 40 may be provided on the upper and lower sides of the slider 22, respectively. In this case, both ends of each elastic member 40 may not be connected to the slider 22 and the stopper 12.

At this time, the upper elastic member 40 may be stretched or gradually stretched or simply descends with the slider 22. When the lifting bracket 20 ascends, the upper elastic member 40 is compressed and applies a downward elastic force to the slider 22. At this time, the lower elastic member 40 may be stretched or gradually stretched, which is not limited here.

[0064] Please refer to Figure 3 In some embodiments of the present application, an installation space 221 is formed in the slider 22, and an opening communicating with the installation space 221 is formed at the bottom of the slider 22;

[0065] The guide portion 13 passes through the top wall of the installation space 221 , and at least a portion of the elastic member 40 is inserted into the installation space 221 from the opening of the installation space 221 and abuts against the top wall of the slider 22 .

[0066] In this embodiment, an installation space 221 is formed inside the slider 22, and an opening connected to the installation space 221 is opened at the bottom of the slider 22. At this time, the guide portion 13 is penetrated by the installation space 221, and the end of the elastic member 40 facing the slider 22 can be inserted into the installation space 221. In this way, the installation space 221 can be used to protect and limit the elastic member 40 to prevent the spring from deforming toward the outside of the stop portion 12 and the lifting bracket 20 when it is squeezed; in addition, by accommodating part of the elastic member 40 using the installation space 221, the combined height of the elastic member 40 and the slider 22 can be reduced, thereby reducing the height of the lifting bracket 20 and reducing the volume and occupied space of the drive device 100.

[0067] Please refer to Figure 4 In some embodiments of the present application, the lifting bracket 20 is provided with a guide sleeve 23, the guide sleeve 23 is connected to the slider 22, and the guide sleeve 23 is provided with a guide hole extending in the height direction;

[0068] The guide sleeve 23 is sleeved on the guide portion 13 through the guide hole and is slidably connected to the guide portion 13 .

[0069] In this embodiment, a guide sleeve 23 is provided in the slider 22. The guide sleeve 23 is generally a columnar structure and is provided with a guide hole that penetrates in the height direction, so that the guide portion 13 is provided in the guide hole and passes through the top wall of the installation space 221. In this way, when the installation space 221 is provided in the slider 22 for accommodating and protecting the elastic member 40, the guide sleeve 23 can be used to increase the contact length and contact area between the lifting bracket 20 and the guide portion 13, thereby improving the stability of the connection and cooperation between the guide portion 13 and the lifting bracket 20. The guide sleeve 23 can be provided in the installation space 221 or outside the installation space 221, which is not limited here.

[0070] In this embodiment, the elastic member 40 and the guide sleeve 23 can be sleeved on the same guide portion 13, so that the end of the elastic member 40 facing the slider 22 abuts against the guide sleeve 23, or a spring with a larger diameter is provided on the outside of the guide sleeve 23. Alternatively, two guide portions 13 can be provided in the following embodiment to respectively sleeve the guide sleeve 23 and the elastic member 40.

[0071] Combined with reference Figure 3 and Figure 4 In some embodiments of the present application, at least two guide portions 13 are connected to the same stop portion 12;

[0072] The guide sleeve 23 is sleeved on one of the guide portions 13 , and the elastic member 40 is sleeved on the other guide portion 13 . The distance between the guide sleeve 23 and the back plate 21 is smaller than the distance between the elastic member 40 and the back plate 21 .

[0073] The technical solution of the aforementioned embodiment is to provide an installation space 221 in the slider 22 for accommodating the protective elastic member 40 , and to provide a guide sleeve 23 to improve the stability of the connection between the guide portion 13 and the lifting bracket 20 . In this embodiment, two guide portions 13 arranged side by side are protruded on the stopper portion 12, so that one of the guide portions 13 is inserted into the guide sleeve 23, and the other guide portion 13 is used to sleeve the elastic member 40. In this way, the lifting bracket 20 can be limited at least twice by using at least two guide portions 13, thereby improving the stability of the sliding process of the driving device 100; in addition, compared with the method of sleeve-connecting the guide sleeve 23 and the elastic member 40 on the same guide portion 13 and making the elastic member 40 abut against the guide sleeve 23, the guide sleeve 23 and the elastic member 40 are sleeved on the two guide portions 13 respectively, so that the elastic member 40 is prevented from being rolled between the guide sleeve 23 and the guide portion 13 when the guide sleeve 23 slides along the guide portion 13, thereby preventing the guide sleeve 23 and the lifting bracket from being obstructed and interfered when sliding along the guide portion 13; in addition, compared with the method of selecting a spring with a larger diameter to be sleeved on the outer side of the guide sleeve 23, it is avoided that the gap between the spring and the guide portion 13 is too large, resulting in the inability to guide the extension and contraction of the spring well. That is, in this embodiment, two guide parts 13 are provided, and the guide sleeves 23 and the springs are respectively sleeved on the two guide parts 13 , which is beneficial to improving the stability of the lifting bracket 20 during the movement process.

[0074] In addition, in the present embodiment, the distance between the guide sleeve 23 and the back plate 21 is smaller than the distance between the elastic member 40 and the back plate 21. It can be understood that the guide sleeve 23 is connected to the slider 22. At this time, the contact area between the side of the slider 22 close to the back plate 21 and the guide portion 13 is larger than the contact area of ​​the side of the slider 22 far from the back plate 21 and where the installation space 221 is opened. As a result, the lifting bracket 20 is supported by a relatively stable force at a position close to the mounting bracket 10, thereby avoiding the lifting bracket 20 and the processing head 200 from tilting due to the small contact area on the inner side of the lifting bracket 20 when the mass of the lifting bracket 20 and the processing head 200 is large, thereby ensuring the connection stability between the lifting bracket 20 and the mounting bracket 10.

[0075] Please refer to Figure 4 In some embodiments of the present application, a stopper is provided on each side of the mounting surface, and the driving device 100 is provided with at least two elastic members 40 , each of which is provided between a stopper and the lifting bracket 20 .

[0076] In this embodiment, two stoppers are respectively arranged on both sides of the driving device 100, and elastic members 40 are correspondingly arranged between the two stoppers and the lifting bracket 20 for elastically supporting the lifting bracket 20, so that both sides of the lifting bracket 20 are elastically supported by the elastic members 40, so that the lifting bracket 20 is subjected to balanced force, and the lifting bracket 20 is prevented from being displaced. The elastic members 40 on both sides are used to increase the elastic supporting force on the lifting bracket 20, and the lifting bracket 20 and the components fixed by the lifting bracket 20 are more effectively prevented from falling due to excessive weight, thereby improving the safety of use. In addition, the elastic members 40 arranged at different positions can be the same or different, and can all be springs, or different elastic structures such as springs, elastic top columns or elastic airbags can be respectively adopted, which is not limited here.

[0077] Please refer to Figures 1 to 3 In some embodiments of the present application, the driving structure 30 includes a driving member 31, a gear 32 and a rack 33, the rack 33 extends in the height direction and is connected to the lifting bracket 20, and the gear 32 is transmission-connected to the driving member 31 and meshes with the rack 33.

[0078] In this embodiment, the driving structure 30 includes a rack 33 connected to the lifting bracket 20 and extending along the lifting direction of the lifting bracket 20, a gear 32 meshing with the rack 33 to drive the rack 33 to slide along the height direction, and a driving member 31 for driving the gear 32 to rotate. When the driving member 31 drives the gear 32 to rotate, the gear 32 will move the rack 33 to slide along the length direction of the rack 33, thereby driving the lifting bracket 20 to rise and fall. The driving member 31 can be a driving motor, which can directly make the gear 32 sleeved on the output shaft 311 of the driving motor and rotate with the output shaft 311, or at least one transmission mechanism such as a belt transmission mechanism, a gear 32 transmission mechanism, a connecting rod transmission mechanism, etc. can be set between the driving motor and the gear 32 to achieve a transmission connection between the driving motor and the gear 32. Of course, the driving member 31 can also be a cylinder or a hydraulic cylinder that drives the gear 32 to rotate through a transmission mechanism. This is not limited here, and it is only necessary to realize that the lifting bracket 20 can be automatically lifted and lowered.

[0079] In addition, in the driving device 100, the lifting bracket 20 is used to install components that need to be lifted and lowered, so that the lifting bracket 20 can be driven by the driving structure 30 to be lifted and lowered relative to the mounting bracket 10, and an elastic member 40 is arranged between the lifting bracket 20 and the stopper 12 of the mounting bracket 10, so that the elastic member 40 provides an upward elastic force to elastically support the lifting bracket 20. In addition, the elastic member 40 supports the lifting bracket 20 upward, so that the lifting bracket 20 can apply an upward supporting force to the rack 33 of the driving structure 30, so that the rack 33 and the gear 32 always maintain a good contact and meshing state, eliminate the reverse clearance between the gear 32 and the rack 33, avoid the lifting error and slipping idling problems caused by the reverse clearance between the rack 33 and the gear 32 during the reciprocating lifting process, improve the accuracy and stability of the lifting movement, and thus improve the accuracy of the processing equipment 1000; and the meshing state between the gear 32 and the rack 33 is automatically adjusted by the elastic member 40, without the user disassembling the equipment to adjust the transmission clearance for maintenance, thereby improving the convenience of use of the processing equipment 1000.

[0080] Combined with reference Figure 1 and Figure 3 In some embodiments of the present application, the mounting bracket 10 is provided with an avoidance groove 14, and the rack 33 and the gear 32 are arranged in the avoidance groove 14;

[0081] The output shaft 311 of the driving member 31 passes through the mounting bracket 10 and is drivingly connected to the gear 32 .

[0082] In the technical solution of the present application, the driving member 31 of the driving structure 30 is connected to the lifting bracket 20 through the gear 32 and the rack 33 to drive the lifting bracket 20 to rise and fall along the mounting surface. In this embodiment, an avoidance groove 14 is opened on the mounting surface, and the rack 33 and the gear 32 are both arranged in the avoidance groove 14. A driving motor is arranged as the driving member 31, and the driving motor is arranged on the back side of the mounting bracket 10, so that the output shaft 311 of the driving motor transmits the mounting bracket 10 into the avoidance groove 14 and is connected to the gear 32. With such an arrangement, the gear 32 and the rack 33 are sunken into the mounting surface by utilizing the avoidance groove 14, thereby reducing the combined thickness of the mounting bracket 10 and the lifting bracket 20, and reducing the thickness and volume of the driving device 100.

[0083] Please refer to Figure 6The present application also proposes a processing device 1000, the processing device 1000 includes a driving device 100 as described in any of the above items. The specific structure of the driving device 100 refers to any of the above embodiments and will not be described in detail here. The processing device 1000 proposed in the present application can be, for example, a knife cutting processing device 1000 such as a mechanical engraving machine, a mechanical drilling machine, or a laser processing device 1000 such as a laser cutting machine, a laser engraving machine, a laser marking machine, and a 3D printer. The processing head 200 such as a laser head and a print head needs to be adjusted according to the height of the processing surface or the number of printing layers, or the height of components such as a distance measuring sensor needs to be adjusted. The driving device 100 includes a mounting bracket 10 as a mounting base. The mounting bracket 10 can be set on the frame 300 of the processing equipment 1000. In some embodiments, the mounting bracket 10 can also be set on a translation structure, which is not limited here. The mounting bracket 10 is provided with a mounting surface that is approximately vertical, so that the lifting bracket 20 of the driving device 100 can be lifted and lowered on the mounting surface. The mounting surface can limit the lifting bracket 20 and provide a sliding surface for the lifting bracket 20. The lifting bracket 20 is used to install components that need to be lifted on the processing equipment 1000, such as a tool of the knife cutting processing equipment 1000, a laser head in the laser processing equipment 1000, The print head in the 3D printer or the sensor that needs to be lifted and lowered, etc., so that the components can be lifted and lowered on the mounting surface with the lifting bracket 20; the driving device 100 is also provided with a driving structure 30 for driving the lifting bracket 20 to lift and lower. The driving structure 30 can be at least one of an electric structure, a pneumatic structure or a hydraulic structure, and can be connected to the lifting bracket 20 through a transmission structure such as a gear transmission, a screw transmission, a belt transmission, a gear rack transmission, a worm gear transmission, etc., so as to drive the lifting component to move relative to the mounting bracket 10, thereby realizing the lifting and lowering of the processing head 200, and can more accurately control the lifting height of the processing head 200, and improve the degree of automation of the processing equipment 1000.

[0084] Optionally, in the driving device 100 of the present application, a stopper 12 is convexly provided on the mounting surface of the mounting bracket 10. The stopper 12 can be integrally formed with the main body of the mounting bracket 10, or can be detachably or non-detachably installed on the mounting surface; so that part of the lifting bracket 20 is located above the stopper 12, the descending range of the lifting bracket 20 can be limited to prevent the lifting bracket 20 from falling out of the mounting bracket 10. In addition, an elastic member 40 is provided between the stopper 12 and the lifting bracket 20. When the lifting bracket 20 descends or the elastic member 40 is pressed under the action of gravity to shrink and deform, the elastic member 40 generates an elastic force to push upward. The lifting bracket 20 is supported by the elastic member 40. If the driving structure 30 fails, the elastic member 40 can prevent the lifting bracket 20 and the components fixed thereon from falling due to being too heavy. In addition, during the lifting process of the lifting bracket 20, the elastic member 40 applies an upward holding force to the rack 33 of the driving structure 30 through the lifting bracket 20, so that the rack 33 and the gear 32 always maintain a good contact and meshing state, eliminating the backlash between the gear 32 and the rack 33, avoiding the lifting error and slipping and idling problems caused by the backlash between the rack 33 and the gear 32 during the reciprocating lifting process, and improving the accuracy and stability of the lifting movement.

[0085] In addition, the elastic member 40 supports the lifting bracket 20 upward, so that an upward supporting force can be applied to the rack 33 of the driving structure 30 through the lifting bracket 20, so that the rack 33 and the gear 32 always maintain a good contact and meshing state, eliminating the reverse clearance between the gear 32 and the rack 33, avoiding the lifting error and slipping and idling problems caused by the reverse clearance between the rack 33 and the gear 32 during the reciprocating lifting process, improving the accuracy and stability of the lifting movement, thereby improving the accuracy of the processing equipment 1000; and the meshing state between the gear 32 and the rack 33 is automatically adjusted by the elastic member 40, without the user having to disassemble the equipment to adjust the transmission clearance for maintenance, thereby improving the convenience of use of the processing equipment 1000.

[0086] Since the processing equipment 1000 proposed in the present application applies all the technical solutions of all the aforementioned embodiments, it at least has all the beneficial effects brought by all the aforementioned embodiments, which will not be described one by one here.
