DETAILED DESCRIPTION

[0024] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0025] In the related art, the distance between the lower end surface of the equipment front end module and the ground is small, and it is difficult for the forklift's front fork to extend deeply into the lower end of the equipment front end module to lift the equipment front end module. If the equipment front end module is placed on the fork of the forklift with the assistance of on-site personnel, it requires the cooperation of multiple people.

[0026] In order to overcome the above-mentioned problems, the present embodiment provides a lifting tool, in which the position of the beam in the supporting device is relatively low, so as to facilitate extension into the lower end of the equipment. Then the hydraulic pump provides pressure medium to the hydraulic jack, and the pressure medium is used to drive the hydraulic jack to rise, thereby lifting the equipment through the supporting seat and the beam to adjust the height of the equipment.

[0027] This embodiment provides a lifting tool that can drive equipment to be lifted, wherein the equipment may be a front-end equipment module or other semiconductor production equipment.

[0028] The lifting tooling includes: a hydraulic pump 100 for providing a pressure medium; a hydraulic jack group 200, which is connected to the hydraulic pump 100 through a pipeline; a support device 300, which has a crossbeam 310 and a support seat 320, and the support seats 320 are respectively matched with multiple hydraulic jacks 210 of the hydraulic jack group 200, and the crossbeam 310 is connected between two adjacent support seats 320, and the crossbeam 310 is connected to the support seat 320 near the lower end; wherein the hydraulic pump 100 is used to provide a pressure medium to the hydraulic jack 210 to drive the hydraulic jack 210 to adjust the height of the equipment 400 through the support device 300.

[0029] Optionally, in order to improve the stability of the device 400 during the lifting movement, the hydraulic jack group 200 may include multiple groups, and the multiple groups of hydraulic jack groups 200 are spaced apart along a preset direction; the preset direction is perpendicular to the axial direction of the hydraulic jack 210 and the axial direction of the crossbeam 310 in the support device 300. For example, the support device 300 can span the bottom of the device 400, and the multiple groups of hydraulic jack groups 200 can be spaced apart along a direction perpendicular to the support device 300 and the hydraulic jack 210. Among them, the number of support devices 300 can be adapted to the number of hydraulic jack groups 200. The specific number of hydraulic jacks 210 can be set according to actual needs.

[0030] Optionally, in order to reduce the cost and the difficulty of synchronous control, the hydraulic jack group 200 can have two groups, three groups, four groups or more than four groups. For ease of description, the following will be described by taking the hydraulic jack group 200 having two groups as an example, and correspondingly, the supporting device 300 also has two groups.

[0031] In other embodiments, the hydraulic jack group 200 may have a group, and correspondingly, the supporting device 300 also has one. The cross beam 310 in the supporting device 300 may be connected to a supporting plate, and the upper surface of the supporting plate has a relatively large area to facilitate improving the supporting reliability of the lifting tooling.

[0032] The hydraulic jack group 200 may include two hydraulic jacks 210, and the two hydraulic jacks 210 are connected through a supporting device 300. The supporting device 300 includes two supporting seats 320, and the two supporting seats 320 can respectively cooperate with the two hydraulic jacks 210. The crossbeam 310 in the supporting device 300 is connected between the two supporting seats 320, and the crossbeam 310 is used to carry the equipment 400, so that when the hydraulic jack 210 performs an upward movement under the action of the pressure medium provided by the hydraulic pump 100, the equipment 400 is lifted through the supporting device 300.

[0033] In other examples, the hydraulic jack group 200 may include at least three hydraulic jacks 210 , wherein a supporting device 300 may be connected between every two adjacent hydraulic jacks 210 , so as to be able to adjust the heights of a plurality of devices 400 at the same time.

[0034] Exemplarily, the support seat 320 may be provided with a receiving groove, and the hydraulic jack 210 may be located in the receiving groove to ensure the reliability of the connection between the hydraulic jack 210 and the support seat 320. The lower part of the support seat 320 is connected to the crossbeam 310, so that the position of the crossbeam 310 is relatively low, which is conducive to entering the bottom of the device 400 to lift the device 400.

[0035] The crossbeam 310 can be detachably connected to one of the support seats 320 to improve the flexibility of the lifting tool during use. For example, the crossbeam 310 is fixedly connected to one of the support seats 320, and the crossbeam 310 is detachably connected to the other support seat 320. For another example, the crossbeam 310 is detachably connected to the two support seats 320. Among them, the crossbeam 310 can be detachably connected to the support seat 320 by plugging or fastening.

[0036] Optionally, by detachably connecting the crossbeam 310 and the two support seats 320, it is convenient to select a crossbeam 310 of matching size to cooperate with the support seats 320 according to the size change of the equipment 400, thereby improving the flexibility of the lifting tooling.

[0037] In other examples, in order to improve the convenience of operation, the crossbeam 310 can be fixedly connected to the two support seats 320 respectively.

[0038] In some examples, the hydraulic pump 100 can be manually operated. The hydraulic pump 100 has a pump body and a pressure rod, and the pump body has an exhaust hole and a hydraulic oil port. When the front module of the lifting equipment needs to be lifted, the exhaust hole and the hydraulic oil port are opened, and the pressure plate is pressed, so that the hydraulic pump 100 provides a pressure medium to the hydraulic jack 210. Among them, the pressure medium may include at least one of the following: hydraulic oil.

[0039] In other examples, the lifting tool may further include a controller, which is electrically connected to the hydraulic pump 100, and the controller may be used to control the working state of the hydraulic pump 100, for example, to control the hydraulic pump 100 to extract the pressure medium and provide it to the hydraulic jack 210. The controller may be communicatively connected to an input device, and the input device is used to receive input instructions, and the controller controls the working state of the hydraulic pump 100 according to the input instructions.

[0040] Correspondingly, the crossbeam 310 may be equipped with a detection element, which is electrically connected to the processor, and the processor is electrically connected to the controller. The detection element is used to detect the movement distance of the crossbeam 310 and send it to the processor. The processor obtains the current position of the device front-end module based on the movement distance of the crossbeam 310; the processor determines whether the device front-end module has reached the predetermined position based on the current position of the device front-end module, until the processor determines that the device front-end module has reached the predetermined position, then the processor sends a stop signal to the controller, and the controller controls the hydraulic pump 100 to stop based on the stop signal. Among them, the detection element may include at least one of the following: a distance measuring sensor, an image acquisition.

[0041] In this example, by developing controllers, processors, and detection elements, etc., it is easy to improve the degree of automation of the lifting tooling, save manpower, and improve the convenience of handling or packaging equipment.

[0042] The lifting tooling provided in this embodiment is provided with a hydraulic pump 100, a hydraulic jack group 200 and a supporting device 300. The hydraulic jack group 200 is connected to the hydraulic pump 100 through a pipeline; the supporting device 300 has a crossbeam 310 and a supporting seat 320. The supporting seats 320 respectively cooperate with multiple hydraulic jacks 210 of the hydraulic jack group 200. The crossbeam 310 is connected between two adjacent supporting seats 320, and the crossbeam 310 is connected to the part of the supporting seat 320 near the lower end; in this way, the position of the crossbeam 310 in the supporting device 300 is relatively low, which is convenient for extending into the lower end of the equipment 400. Then the hydraulic pump 100 provides a pressure medium to the hydraulic jack 210, and uses the pressure medium to drive the hydraulic jack 210 to rise, and then the equipment 400 is lifted through the supporting seat 320 and the crossbeam 310 to adjust the height of the equipment 400. In other application scenarios, according to actual needs, the lifting tool can also be used to drive the device 400 to descend, so as to place the device 400 stably on the ground.

[0043] The device 400 provided in this embodiment can be applicable to devices 400 whose lower end faces are relatively close to the ground, such as the front-end modules of devices. The lower-positioned beam 310 can smoothly extend into the lower end of the front-end modules of the devices and be supported on the lower side of the lower end faces of the front-end modules of the devices, thereby reducing the difficulty of packaging or carrying the front-end modules of the devices, which is beneficial to improving efficiency and saving manpower.

Exemplarily, the lower surface of the connecting beam 323 is flush with the lower end surface of the connecting plate 322; or, the lower surface of the connecting beam 323 is slightly higher than the lower end surface of the connecting plate 322. The connecting beam 323 can be prismatic. The supporting seat 320 has a longitudinal center plane parallel to the axial direction of the connecting beam 323 and the vertical direction of the lifting tool, and the central axis of the connecting beam 323 can pass through the longitudinal center plane of the supporting seat 320. Optionally, in order to improve the strength of the supporting seat 320, the connecting beam 323 and the connecting plate 322 can be integrally arranged or welded and fixed.

[0052] In some examples, the arrangement direction of the second ribs 325 is the width direction of the connecting plate 322; then the width of the portion of the connecting plate 322 close to the lower end gradually decreases from top to bottom. Optionally, the upper portion of the connecting plate 322 close to the upper end is roughly rectangular; the lower portion of the connecting plate 322 close to the lower end is roughly trapezoidal.

[0069] The lifting tool provided in this example can be applied to equipment 400 of more sizes and has high flexibility.

[0070] In some embodiments, the hydraulic jack group 200 includes a plurality of groups, and the plurality of hydraulic jack groups 200 are spaced apart and distributed along a preset direction; the preset direction is perpendicular to the axial direction of the hydraulic jack 210 and the axial direction of the beam 310 .

[0071] The hydraulic jack group 200 may include two groups. One group of hydraulic jack groups 200 corresponds to one third of the length direction of the lower end surface of the device 400; the other group of hydraulic jack groups 200 corresponds to two thirds of the length direction of the lower end surface of the device 400. The two groups of hydraulic jacks 210 may be connected to the same hydraulic pump 100; or the two groups of hydraulic jacks 210 may be connected to independent hydraulic pumps 100.

[0072] In other examples, when the volume or weight of the device 400 is large, the hydraulic jack group 200 may also have three or more groups. The specific number of the hydraulic jack group 200 can be set according to actual needs.

[0073] In some examples, there are two groups of hydraulic jack groups 200, and the two groups of hydraulic jack groups 200 are respectively connected to the hydraulic pump 100, and the lengths of the paths of the pressure medium flowing from the hydraulic pump 100 to the two hydraulic jack groups 200 are equal, thereby facilitating the pressure medium to reach the hydraulic jacks 210 in each hydraulic jack group 200 at the same time, thereby ensuring the stability of the equipment 400 during the lifting process.

[0074] The following description will be made by taking the example that each group of hydraulic jacks 210 has two hydraulic jacks 210. When the two groups of hydraulic jack groups 200 are respectively connected to the same hydraulic pump 100, the hydraulic pump 100 can correspond to the two groups of hydraulic jack groups 200; for example, the two groups of hydraulic jacks 210 are respectively matched with two supporting devices 300, and the connecting line segment in the middle of the axial direction of the two supporting devices 300 has a midpoint, and the axial direction of the hydraulic pump 100 can pass through the midpoint. In addition, the arrangement path of the pipeline connecting the hydraulic pump 100 and the hydraulic jack 210 is reasonably set so that the length of the path of the pressure medium flowing from the hydraulic pump 100 to the four hydraulic jack groups 200 is equal.

[0075] For example, with the connecting line segment corresponding to the axial midpoint position of the supporting device 300 corresponding to the two groups of hydraulic jack groups 200 as a reference, the output end of the hydraulic pump 100 can be connected to two first sections of pipelines, the first section of the pipeline is bent at the connecting line segment, the two first sections of the pipeline are respectively bent in the direction toward the corresponding supporting device 300, and the center axis of the bent part of the two first sections of the pipeline coincides with the connecting line segment; when there is a preset distance between the output end of the first section of the pipeline and the supporting device 300, a three-way joint is connected to the output end of the first section of the pipeline, and the two outlets of the three-way joint are respectively connected to two second sections of the pipeline, and the two second sections of the pipeline extend respectively toward the two hydraulic jacks 210 in the same group. The second section of the pipeline can also be bent, or the second section of the pipeline can be linear and there is a preset angle between the center axis of the second section of the pipeline and the connecting line segment, and the output end of the second section of the pipeline is connected to the corresponding hydraulic jack 210.

[0076] In this example, when the device 400 needs to be lifted, the hydraulic pump 100 can be controlled to simultaneously provide pressure medium to the corresponding hydraulic jacks 210 until the device 400 is lifted to a set position, and the hydraulic pump 100 stops providing pressure medium.

[0077] The two groups of hydraulic jacks 210 can be connected to independent hydraulic pumps 100, respectively, and the hydraulic pumps 100 can correspond to the two hydraulic jacks 210 in the same group; for example, the supporting device 300 corresponding to each group of hydraulic jacks 210 has a midpoint along the axial direction of the supporting device 300, and the axial direction of the hydraulic pump 100 corresponding to the hydraulic jack group 200 can pass through the midpoint. In addition, the arrangement path of the pipeline connecting the hydraulic pump 100 and the hydraulic jack 210 is reasonably set, so that the length of the path where the pressure medium flows from the hydraulic pump 100 to the four hydraulic jack groups 200 is equal.

[0078] In this example, when the device 400 needs to be lifted, the two hydraulic pumps 100 can be controlled to simultaneously provide pressure medium to the corresponding hydraulic jacks 210 until the device 400 is lifted to a set position and the hydraulic pumps 100 stop providing pressure medium.
