[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1

[0034] Please see Figure 1-3 A lifting arm for pre-washing and degumming monocrystalline silicon wafers, comprising:

[0035] Steel frame 1 and slide rail 3;

[0036] A sliding component 2 is installed at one end of the steel frame 1. One end of the sliding component 2 abuts against the slide rail 3. The sliding component 2 is used to drive the steel frame 1 to slide along the slide rail 3.

[0037] Drive component 4 is installed at the upper end of steel frame 1;

[0038] The vertical rack 5 is slidably connected to the steel frame 1 and passes through the steel frame 1. One side of the vertical rack 5 meshes with one side of the driving component 4. The driving component 4 is used to drive the vertical rack 5 to slide up and down.

[0039] Hanger 6, the upper end of hanger 6 is connected to the lower end of vertical rack 5;

[0040] The two ends of the internal structure of the hanger 6 are slidably connected to a horizontal rack 7. A connecting strip 8 is installed at one end of the horizontal rack 7, and a hook 9 is installed at the lower end of the connecting strip 8. The material rack is lifted by hooking the material rack through the hook 9.

[0041] according to Figure 1 As shown, the slide rail 3 includes a rack and a slide rail frame, and the sliding component 2 consists of a first drive motor and a first reducer. The output shaft of the first drive motor meshes with the inside of the first reducer, thereby driving the first reducer to rotate. One end of the first reducer is connected to a first spur gear, which meshes with the rack. Thus, when the first reducer drives the spur gear to rotate, the steel frame 1 slides along the sliding component 2.

[0042] The drive component 4 includes a second drive motor and a second reducer. The output shaft of the second drive motor meshes with the interior of the second reducer. The two ends of the second reducer are connected to second spur gears. The second spur gears mesh with the vertical rack 5, thereby driving the second reducer to rotate through the second drive motor. The second reducer drives the second spur gears to rotate, and the rotation of the second spur gears drives the vertical rack 5 to slide up and down. In this way, the vertical rack 5 drives the hanger 6 and the hook 9 to slide, so that the hook 9 can approach the material rack.

[0043] The upper end of its material rack is equipped with two lifting rods, which are hooked by hook 9 to achieve hoisting;

[0044] according to Figure 1 and Figure 2 As shown, when the hook 9 moves downwards and approaches the material rack, the two horizontal racks 7 slide relative to each other, causing the horizontal racks 7 to push the connecting bar 8 and the hook 9 to slide, thus allowing the hook 9 to gradually approach the lifting rod at the top of the material rack. A button 18 is installed at one end of the hook 9. When the lifting rod presses the button 18, the button 18 sends a signal, indicating that the hook 9 is connected to the lifting rod, and that the hook 9 is now hooked on the lifting rod. In this way, the driving component 4 drives the vertical rack 5 to slide upwards, which in turn drives the lifting frame 6 and the hook 9 to hook the material rack upwards, thus realizing automatic hooking of the material rack and improving lifting efficiency.

[0045] The drive gear 10 is installed inside the hanger 6;

[0046] The outer surface of the transverse rack 7 is provided with a rack, and the drive gear 10 meshes with the rack. Rotating the drive gear 10 drives the rack and the transverse rack 7 to slide.

[0047] The two transverse racks 7 slide relative to each other.

[0048] By rotating the drive gear 10, the drive gear 10 meshes with the rack of the horizontal rack 7, thereby causing the drive gear 10 to drive the upper and lower horizontal racks 7 to slide relative to each other.

[0049] Example 2

[0050] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 1-3 One end of the horizontal rack 7 is sequentially fitted with a first round sleeve 12 and a second round sleeve 13, with the second round sleeve 13 located above the first round sleeve 12.

[0051] A round shaft 11 is installed at the upper end of the connecting bar 8, and the round shaft 11 is rotatably connected to the first round sleeve 12 and the second round sleeve 13;

[0052] The inner wall of the second sleeve 13 is also equipped with an airbag ring 14, which clamps the outer surface of the round shaft 11 through the inflated airbag ring 14.

[0053] The motor is installed inside the hanger 6, and one side of the motor is connected to one side of the drive gear 10;

[0054] A button 18 is installed at one end of the hook 9, and the button 18 is electrically connected to the motor.

[0055] When the material rack is placed at an angle, the circular shaft 11 at the upper end of its connecting bar 8 is rotatably connected to the first circular sleeve 12. The circular shaft 11 and the first circular sleeve 12 are connected by a bearing. When the lifting rod on the material rack abuts against one of the lifting hooks 9, only one button 18 sends a signal because the material rack is tilted. At this time, the drive gear 10 will continue to rotate, thus continuing to push the horizontal rack 7 to slide. This causes the material rack to push the connecting bar 8 to tilt in the opposite direction, thereby making the connecting bar 8 parallel to the lifting rod. In this way, the lifting rod presses two buttons 18, and the two buttons 18 send a signal to stop the drive gear 10 from rotating. This allows the connecting bar 8 to rotate and adapt when the material rack is tilted, which facilitates hoisting.

[0056] A contact plate 16 is slidably connected to one end of the hook 9. The contact plate 16 is connected to the hook 9 by a support spring 17. The contact plate 16 is used to press the button 18.

[0057] Furthermore, by installing the contact plate 16, the pressing area of ​​the button 18 is increased, thereby improving the pressing sensitivity. Then, when the hook 9 drives the contact plate 16 to contact the boom, the button 18 is pressed through the contact plate 16.

[0058] It should be noted that a torque spring is also installed at the upper end of the connecting bar 8, and the connecting bar 8 is connected to the first circular sleeve 12 through the torque spring.

[0059] Example 3

[0060] This embodiment is an improvement upon embodiment 5. For details, please refer to [link / reference]. Figure 1-3One end of the second sleeve 13 is equipped with an air nozzle 15, and one end of the air nozzle 15 is connected to the air pump through a hose.

[0061] Air is supplied to the airbag ring 14 through the air nozzle 15;

[0062] Button 18 is also electrically connected to the air pump.

[0063] Furthermore, since the round shaft 11 is rotatably connected to the first round sleeve 12, in order to reduce the swaying of the connecting strip 8 during hoisting, it is necessary to fix the round shaft 11. Then, when the button 18 sends a signal to stop the drive gear 10 from rotating, the button 18 will also send a signal to the air pump, so that the air pump transmits air to the air nozzle 15 through the hose, thereby inflating the airbag ring 14, and using the inflated airbag ring 14 to fix the round shaft 11.

[0064] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0065] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
