Detailed Implementation

[0035] The present invention will now be described in further detail with reference to the embodiments and accompanying drawings. However, this should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0036] Example

[0037] See Figure 1-8 A docking device for a negative pressure container, used to support the top of the negative pressure container and to allow workpieces to enter and exit the negative pressure container, such as a vacuum chamber, the docking device comprising:

[0038] Frame 1 is made of rectangular square steel welded together and includes a bottom frame, columns and a top frame. Frame 1 serves as the mounting carrier for the drive mechanism and the lifting mechanism, and also as a support bracket for the negative pressure container. The top frame is provided with docking holes 11 corresponding to the inlet and outlet holes of the negative pressure container, which are used as channels for supporting the base 4 and the workpiece. In addition, the top frame is provided with 4 support pads 12 for supporting the negative pressure container.

[0039] The lifting mechanism is fixed on the frame 1 and is equipped with a positioning support component. The positioning support component is equipped with a position-adjustable guide pin 25, which is inserted into the corresponding pin hole of the support base 4 to realize the positioning of the support base 4. The head of the guide pin 25 adopts a conical design to play a guiding role.

[0040] A drive mechanism is fixed to the frame 1 and drives the lifting mechanism to move.

[0041] The support base 4 is detachably connected to the lifting mechanism through the positioning support assembly. The support base 4 is used to rise from the bottom of the frame 1 and pass through the docking hole 11 to cover the inlet and outlet of the negative pressure container. The support base 4 achieves sealing with the inlet and outlet of the negative pressure container through the sealing ring 41 on the support base 4.

[0042] In this embodiment, during the docking process with the negative pressure container, the workpiece is placed on the support base 4. The guide pin 25 in the positioning support assembly can precisely adjust the position of the support base 4, ensuring stable docking with the inlet and outlet holes of the negative pressure container. The lifting mechanism allows the support base 4 to rise or fall smoothly, improving the accuracy and safety of the docking. This utility model achieves efficient and stable docking between the docking device and the negative pressure container through the synergistic effect of the frame 1, the lifting mechanism, the drive mechanism, and the support base 4.

[0043] See Figure 1-2 In this embodiment, the lifting mechanism includes two lifting units mirror-distributed on both sides of the support base 4, and the lifting unit includes:

[0044] A lifting screw 21 is mounted on the frame 1.

[0045] A crossbeam 22 is slidably connected to the frame 1 at both ends via linear guide rails. The crossbeam 22 is fixed to the screw nut of the lifting screw 21, which enables the lifting and lowering of the crossbeam 22. A positioning support assembly is fixed to the crossbeam 22. When the support base 4 is installed on the positioning support assembly, the lifting and lowering of the support base 4 can be achieved via the lifting screw 21. This embodiment employs two mirror-symmetrically distributed lifting units, each with two positioning support assemblies, which together achieve the support positioning and lifting of the support base 4.

[0046] See Figure 1-2 In this embodiment, the driving mechanism includes a drive motor 31, a first commutator 32, a second commutator 33, a third commutator 34, a first drive shaft 35, and a second drive shaft 36.

[0047] The drive motor 31 is connected to the first commutator 32 through a reducer. The first commutator 32 is connected to end A of the first drive shaft 35 and end A of the second drive shaft 36. The power of the drive motor 31 is transmitted to the first drive shaft and the second drive shaft 36 simultaneously through the first commutator 32.

[0048] The B end of the first drive shaft 35 is connected to the second commutator 33 via a single-clamping diaphragm coupling. The second commutator 33 is connected to the third commutator 34 via the third drive shaft 37. The third commutator 34 is connected to the lifting screw 21 of a lifting unit via a single-clamping diaphragm coupling. The B end of the second drive shaft 36 is connected to the fourth commutator 38 via a single-clamping diaphragm coupling. The fourth commutator 38 is connected to the fifth commutator via the fourth drive shaft. The fifth commutator is connected to the lifting screw 21 of another lifting unit via a single-clamping diaphragm coupling. The drive motor 31 enables the lifting screws 21 of the two lifting units to rotate synchronously and at the same speed via the first commutator 32, the second commutator 33, the third commutator 34, the first drive shaft 35, the second drive shaft 36, the fourth commutator 38, the third drive shaft 37, the fourth drive shaft, and the fifth commutator, so as to realize the lifting of the crossbeam 22 and the support base 4. It should be noted that this embodiment uses a single-clamping diaphragm coupling. The stainless steel spring in the single-clamping diaphragm coupling can compensate for radial, angular, and axial deviations between the commutator shaft and the drive shaft, and between the commutator shaft and the lead screw. This can reduce the coaxiality requirements between shafts and lead screws during installation, and has the characteristics of high reliability. At the same time, it is easy to disassemble and facilitates the maintenance of lead screws, commutators, etc.

[0049] See Figure 3-6 In this embodiment, the positioning support assembly includes a base 23, a movable plate 24, and an adjustment assembly. The base 23 includes a vertical plate 231 and a horizontal plate 232. The vertical plate 231 is fixed to the crossbeam 22 of the lifting mechanism by bolts, and the vertical plate 231 has multiple bolt holes. The crossbeam 22 has multiple threaded holes to adjust the vertical position of the base 23. The movable plate 24 is fixed to the horizontal plate 232 of the base 23 by bolts. The horizontal plate 232 has a first bolt hole 233, and the movable plate 24 has a second bolt hole 241 corresponding to the first bolt hole 233. The diameter of the first bolt hole 233 is larger than that of the second bolt hole 241. Since the diameter of the first bolt hole 233 is larger than that of the second bolt hole 241, the bolts locking the movable plate 24 have room for left and right movement in the first bolt hole 233. When the bolts locking the movable plate 24 are loosened, the movable plate 24 can move relative to the horizontal plate 232 of the base 23. The guide pin 25 is fixed on the movable plate 24; the adjustment component is also fixed on the base 23 to adjust the position of the movable plate 24 relative to the base 23, thereby realizing the position adjustment of the support base 4.

[0050] See Figure 3-6In this embodiment, the adjustment assembly includes a first adjustment plate 26, a second adjustment plate 27, and a third adjustment plate 28 fixed on the horizontal plate 232 of the base 23. The first adjustment plate 26, the second adjustment plate 27, and the third adjustment plate 28 are arranged in a U-shape. Each of the first adjustment plate 26, the second adjustment plate 27, and the third adjustment plate 28 is provided with an adjustment bolt that abuts against the movable plate 24. The first adjustment plate 26 and the second adjustment plate 27 are symmetrically distributed on both sides of the movable plate 24. Assuming that the length direction of the crossbeam 22 is the X-axis direction and the direction perpendicular to the crossbeam 22 is the Y-axis direction, the first adjustment plate 26 and the second adjustment plate 27 are used to adjust the position of the movable plate 24 along the X-axis; the third adjustment plate 28 is used to adjust the position of the movable plate 24 along the Y-axis. Specifically, after the support base 4 is placed on the positioning support assembly, when adjustment along the X-axis is required, first loosen the bolts locking the movable plate 24, then loosen the adjusting bolts of the first adjusting plate 26 in each positioning support assembly, and then tighten the adjusting bolts of the second adjusting plate 27 as needed. This will push the movable plate 24 to move along the X-axis. The movable plate 24 drives the support base 4 to move along the X-axis through the guide pin 25, thereby adjusting the position of the support base 4. After the X-axis adjustment is completed, tighten the bolts on the first adjusting plate 26 and the second adjusting plate 27. Adjusting bolts; when adjustment along the Y-axis is required, loosen the adjusting bolts of the third adjusting plate 28 in each positioning support assembly, and then tighten the adjusting bolts of the two third adjusting plates 28 on one crossbeam 22 as needed, and loosen the adjusting bolts of the two third adjusting plates 28 on the other crossbeam 22. The movable plate 24 then moves to the side where the adjusting bolts are tightened. The movable plate 24 drives the support base 4 to move along the Y-axis through the guide pin 25, thereby adjusting the position of the support base 4. After the Y-axis adjustment is completed, tighten the adjusting bolts on the third adjusting plate 28.

[0051] See Figure 6 It should be noted that in this embodiment, the movable plate 24 is provided with an upper mounting hole 242, the horizontal plate of the base 23 is provided with a lower mounting hole 234, the head of the guide pin 25 is a conical structure, the tail of the guide pin 25 is a screw, the guide pin 25 passes through the upper mounting hole 242 and the lower mounting hole 234 from top to bottom, and then the guide pin 25 is locked to the movable plate 24 by a washer 29 and a bolt. A spring is also provided between the guide pin 25 and the movable plate 24. The washer 29 is located in the lower mounting hole 234, and the outer diameter of the washer 29 is larger than the inner diameter of the upper mounting hole 242 and smaller than the inner diameter of the lower mounting hole 234. The allowable movement between the washer 29 and the lower mounting hole 234 provides a basis for the position adjustment of the movable plate 24.

[0052] In this embodiment, see Figure 1-2The frame 1 has an opening on one side. The area inside the frame 1 can be used as a parking area for AGV trolleys. The two lifting units are located on both sides of the parking area. The AGV trolleys can enter and exit the frame 1 according to a preset route. In use, the unloaded AGV trolleys can wait in the parking area. When the lifting screw 21 places the support base 4 on the AGV trolley, the workpiece is transferred automatically throughout the entire process, and the automated production control is completed.

[0053] See Figure 2 In this embodiment, the bottom of the frame 1 is provided with a height adjustment component, which includes a pad 12, a tensioning bolt 13, and a lifting bolt 14. The pad 12 can be fixed to the ground by welding to a pre-embedded steel plate or by expansion bolts. The head of the tensioning bolt 13 is located in the frame 1, and the threaded part of the tensioning bolt 13 is threadedly connected to the pad 12. Tightening the tensioning bolt 13 moves the pad 12 closer to the frame 1. The lifting bolt 14 is threadedly connected to the frame 1, and one end of the lifting bolt 14 presses against the pad 12. Rotating the lifting bolt 14 moves the pad 12 away from the frame 1, thereby lifting the frame 1. The height adjustment component, through the tensioning bolt 13, the lifting bolt 14, and the pad 12 forming a lifting structure, realizes the height adjustment of the frame 1, ensuring that the frame 1 can be installed and fixed on the ground within a certain flatness range.

[0054] In this embodiment, see Figure 9 Multiple negative pressure containers are provided and connected in series. The number of docking devices is the same as the number of negative pressure containers and they are arranged side by side in sequence. One docking device corresponds to one negative pressure container. When multiple negative pressure containers are installed in series, a set number of docking devices are installed side by side in sequence, with one docking device corresponding to one negative pressure container. The overall height is adjusted by the bottom frame adjustment structure to ensure that the top frame height of all docking devices is consistent, thereby ensuring that the height of all negative pressure containers is consistent. The position of the component guide pin 25 can be adjusted by the adjustment component on the lifting mechanism to ensure that the coaxiality between the workpieces on each support base 4 meets the requirements.

[0055] In use, the frame 1 supports the negative pressure container, and the workpiece is placed on the support base 4. The guide pin 25 in the positioning support assembly can precisely adjust the position of the support base 4, ensuring stable docking between the support base 4 and the inlet / outlet of the negative pressure container. The lifting mechanism allows the support base 4 to rise or fall smoothly, improving the accuracy and safety of docking. Through the synergistic effect of the frame 1, lifting mechanism, drive mechanism, and support base 4, this invention achieves efficient and stable docking between the docking device and the negative pressure container, enabling the workpiece to enter and exit the negative pressure container.

[0056] This utility model also arranges several docking devices side by side, with one docking device corresponding to one negative pressure container, so as to be suitable for multiple negative pressure containers to be installed in series. At the same time, the positioning support components ensure that the coaxiality between the workpieces on each support base 4 meets the requirements.

[0057] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
