[0057] The present invention will be further described in detail below with reference to specific embodiments. However, this should not be construed as limiting the scope of the present invention to the following embodiments. All technologies implemented based on the present invention fall within the scope of the present invention.

[0058] Unless otherwise specified, in the description of the specific embodiments of the present invention, the terms indicating orientation or positional relationships such as "upper," "lower," "left," "right," "center," "inside," and "outside" are based on the orientation or positional relationships shown in the accompanying drawings, or are the orientation or positional relationships in which the product / device / apparatus of the present invention is placed when it is conventionally used. These terms of orientation or positional relationships are merely for the purpose of facilitating the description of the present invention or simplifying the description of the specific embodiments to facilitate a quick understanding of the solutions by technicians, and do not indicate or imply that a particular device / component / element must have a specific orientation or be constructed and operated in a specific positional relationship. Therefore, they should not be understood as limitations on the present invention.

[0059] Furthermore, the use of terms such as "horizontal," "vertical," "overhanging," "parallel," and "coaxial" does not necessarily require the corresponding devices / components / elements to be absolutely horizontal, vertical, overhanging, parallel, or coaxial. Rather, they may be slightly tilted or deviated, as long as this does not affect the proper function of the relevant components. For example, "horizontal" simply means that the orientation is more horizontal than "vertical," and does not imply that the structure must be completely horizontal; rather, it may be slightly tilted. "Coaxial" means that the two components are arranged as coaxially as possible, ensuring that they move coaxially or approximately coaxially when their relative positions change. Alternatively, it can be simplified to mean that the corresponding devices / components / elements, when arranged in a "horizontal," "vertical," "overhanging," "parallel," or "coaxial" orientation, can have an error / deviation of ±10% relative to the corresponding orientation, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and even more preferably within ±4%. For example, the deviation in the "coaxial" orientation is controlled within 0.2-1 mm, preferably within 0.2-0.5 mm. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the solution of the present invention.

[0060] In addition, the expressions “first”, “second”, “third”, etc. in the terms are merely used to distinguish the description of the same or similar components, and should not be understood as emphasizing or implying the relative importance of specific components.

[0061] In addition, in the description of the embodiments of the present invention, "several", "a plurality", and "a number" represent at least 2. It can be any number such as 2, 3, 4, 5, 6, 7, 8, 9, and even more than 9.

[0062] Furthermore, in the description of the technical solutions of this utility model, unless otherwise expressly specified / defined / restricted, the terms "disposed," "installed," "connected," "connected," "provided with," "laid," and "arranged" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections. They may be welding, riveting, bolting, threading, or other commonly used connection methods in the art. Such connections may be mechanical, electrical, or communication connections; they may be direct connections, indirect connections through an intermediate medium, or internal connections between two components.

[0107] In one or more embodiments, Figure 16-17 As shown, the lifting device 5 includes a lifting base 52 and a table 51 arranged above the lifting base 52;

[0108] It also includes a lifting assembly disposed in the lifting base 52, and the lifting assembly can drive the table 51 to move along the Z-axis direction;

[0109] The table 51 is connected to the second moving device 6. The table 51 drives the second moving device 6 to move along the Z-axis direction.

[0110] In this embodiment, the lifting device 5 includes a lifting base 52 and a table 51 arranged above the lifting base 52; it also includes a lifting component arranged in the lifting base 52, and the lifting component can drive the table 51 to move up and down on the lifting base 52; the table 51 is connected to the second moving device 6, and the table 51 is used to drive the second moving device 6 to move along the Z-axis direction.

[0111] In an optional embodiment, if Figure 17 As shown, the lifting assembly includes a first wedge block 53 and a second wedge block 54 arranged above and below. The first wedge block 53 is connected to the side of the table 51 close to the lifting base 52, and the second wedge block 54 is installed in the lifting base 52, and the inclined surface of the first wedge block 53 matches the inclined surface of the second wedge block 54.

[0112] The lifting assembly further includes a second screw rod 56 and a second drive nut 57 . The second drive nut 57 is disposed on the second wedge block 54 . The second screw rod 56 can drive the second drive nut 57 to move along the length direction of the second screw rod 56 .

[0113] The second drive nut 57 is driven by the second screw rod 56 to move along the length direction of the second screw rod 56, thereby causing the second wedge block 54 to move. Since the inclined surface of the first wedge block 53 cooperates with the inclined surface of the second wedge block 54, that is, the inclined surface of the first wedge block 53 contacts the inclined surface of the second wedge block 54, when the second wedge block 54 is displaced, the first wedge block 53 can move up and down under the cooperation of the two inclined surfaces, thereby causing the first wedge block 53 to drive the table top 51 to move up and down, realizing the lifting function.

[0114] Among them, Figure 17-Figure 19 As shown, a front end plate 520 is provided on the lifting base 52, and a second screw rod 56 passes through the front end plate 520. Two sets of slide rail pairs 510 are installed between the front end plate 520 and the first wedge block 53. The first wedge block 53 moves up and down along the front end plate 520 through the slide rail pairs 510.

[0115] The slide rail pair 510 includes a slide rail 511 and a fixed block 512 that cooperate with each other. The slide rail 511 can slide vertically on the fixed block 512. The front end plate 520 has a protrusion 521 on the side close to the first wedge block 53. The fixed block 512 is vertically fixed on the protrusion 521. The slide rail 511 is vertically fixed on the side of the first wedge block 53 close to the front end plate 520. When the second wedge block 54 moves, the first wedge block 53 moves up and down along the front end plate 520 through the slide rail pair 510. Figure 21 .

[0116] In an optional embodiment, if Figure 16 、 Figure 17 As shown, the lifting motor 55 is further included. The lifting motor 55 is connected to the second screw rod 56 through a fourth coupling 530, and the second screw rod 56 is driven to rotate by the lifting motor 55.

[0117] In an optional embodiment, if Figure 18 、 Figure 20 As shown, the inclined guide rails 58 are further included. The inclined guide rails 58 are provided on the first wedge block 53 and the second wedge block 54. The inclined guide rails 58 include a first inclined guide rail 581 and a second inclined guide rail 582 that slide against each other. The second inclined guide rail 582 is installed on the inclined surface of the second wedge block 54, and the first inclined guide rails 581 are installed on both sides of the inclined surface of the first wedge block 53. By providing the inclined guide rails 58, the contact between the inclined surfaces of the second wedge block 54 and the first wedge block 53 is smoother.

[0118] like Figure 18Two sets of second linear guide pairs 59 are installed between the second wedge block 54 and the lifting base 52. The second linear guide pairs 59 are used to realize the horizontal displacement of the second wedge block 54 on the lifting base 52. That is, the second screw rod 56 drives the second drive nut 57 to move along the length direction of the second screw rod 56, and the second drive nut 57 drives the second wedge block 54 to move horizontally on the lifting base 52. When the lifting base 52 moves horizontally, it drives the first wedge block 53 to move up and down along the front end plate 520.

[0119] In an optional embodiment, if Figure 21 As shown, the second displacement probe 550 and the second sensor 560 are used in conjunction with each other. The second displacement probe 550 is mounted on the first wedge block 53, and the second sensor 560 is mounted on the front end plate 520. When the first wedge block 53 moves up and down along the front end plate 520, when the second displacement probe 550 passes by the second sensor 560, the second sensor 560 monitors the displacement of the second displacement probe 550, thereby monitoring the displacement of the first wedge block 53.

[0120] like Figure 19 As shown, a front end plate 520, a rear end plate 580 and two side plates 540 are provided on the lifting base 52. The front end plate 520, the rear end plate 580 and the two side plates 540 form a frame structure, and components such as the first wedge block 53 and the second wedge block 54 are located in the frame structure;

[0121] like Figure 18 As shown, a strip hole 541 is opened on one of the side plates 540, and the second displacement probe 550 passes through the strip hole 541 and is connected to the first wedge block 53. When the first wedge block 53 moves up and down along the front end plate 520, the second displacement probe 550 located on the outside of the side plate 540 cooperates with the second sensor 560 to monitor the displacement of the first wedge block 53.

[0122] The fourth baffle 570 is also included. The fourth baffle 570 is in a broken line shape and is used to cover the second displacement probe 550 and the second sensor 560 to prevent the second displacement probe 550 and the second sensor 560 from being accidentally damaged.

[0123] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
