A washer 4 1515 is provided between 514 and the round nut 4 1516, the end cover 1517 is fixedly connected to the box body 1519 to play a sealing role, and is out of contact with the round nut 4 1516 to avoid friction during movement, and two bearings 2 1512 are sleeved in sequence near the end position of the other end of the worm 1518, and a washer 3 1513 is provided between the two bearings 2 1512, and the two bearings 2 1512 are fixedly installed on the right inner wall of the box body 1519 and the corresponding position of the bearing 3 1514;

[0051] One side of the box 1519 is fixedly connected with the motor seat 1506 through the gland 1511, and the motor 1507 is fixedly connected in the motor seat 1506 through the fastening screw 1508.

[0052] like Figure 5 As shown, the manual assembly 10 includes a transmission shaft 1019, a handwheel 1018 is sleeved on the outer circumference of one end of the transmission shaft 1019, a handle 1001 is fixedly installed on the outer side of the handwheel 1018, the center of the handwheel 1018 is fixedly connected to the left end of the transmission shaft 1019 through a stop pin 1020 to limit the handwheel 1018 from sliding out of the transmission shaft 1019, and grooves A and grooves B are opened on the transmission shaft 1019 inside the handwheel 1018 at intervals along the circumferential direction, as shown in FIG. Figure 5As shown, the inner bottom of the hand wheel 1018 is movably connected to a spring 1016 through a nut 1017, and the end of the spring 1016 away from the nut 1017 is movably connected to a metal ball 1015, and the metal ball 1015 matches the groove. The right end of the transmission shaft 1019 is connected to a pinion 1008 through a flat key 1007, and a round nut 2 1010 is screwed on the end of the transmission shaft 1019, and a washer 1009 is installed between the pinion 1008 and the round nut 2 1010.

The inner rings of the two bearings 1003 are sleeved on the transmission shaft 1019, and the outer rings are jointly sleeved with a bearing seat 1006, and the bottom of the bearing seat 1006 is fixed to the top plate 1.

[0053] In order to realize manual locking maneuver, the hand wheel 1018 must be pushed forward and meshed with the transmission shaft to transmit torque. Before the hand wheel 1018 transmits torque, the drive circuit of the motor must be powered off. A travel switch can be set up, and the normally closed contact of the travel switch can be connected in series in the drive circuit. Alternatively, a normally closed electromagnetic clutch can be added between the motor shaft and the transmission shaft. When the hand wheel touches the travel switch, the electromagnetic clutch is activated, so that the motor shaft is separated from the transmission shaft and power is not transmitted.

[0054] A travel switch support plate 1004 is fixedly connected to the top of the bearing seat 1006, and a travel switch 1002 is fixedly connected to one end of the travel switch support plate 1004. The travel switch 1002 is located above the groove B. The travel switch 1002 is electrically connected to the controller. A sleeve 1005 is sleeved on the transmission shaft 1019 located between the two bearings 1003. A hole elastic retaining ring 1011 is installed on the transmission shaft 1019 at a position outside the bearing 1003 for axial limiting. A washer 2 1012 is also arranged between the hole elastic retaining ring 1011 and the bearing 1003.

[0055] When the metal ball 1015 of the handwheel 1018 is stuck in the groove A position, the handwheel 1018 is disengaged from the toothed clutch 1014, and no torque is transmitted to the screw. At the same time, the handwheel 1018 is not in contact with the travel switch 1002, and the latter's normally closed contacts continue to be closed, which does not affect the motor state. When the handwheel 1018 is pushed to the right along the transmission shaft 1019 until the metal ball 1015 is just stuck in the groove B position, the handwheel 1018 first contacts the travel switch 1002, so that the latter's normally closed contacts in the drive circuit of the motor system are disconnected, and the controller controls the motor 1507 to cut off the power to turn off the motor state, and then the handwheel 1018 engages with the toothed clutch 1014 to transmit torque to the screw.

[0056] like Figure 7As shown, the electromagnetic clutch assembly 30 includes a clutch support 301 fixed to the bottom of the base plate 6. The clutch support 301 is a cavity structure and is integrally sleeved with the outer periphery of the bottom end of the lead screw subassembly. The clutch support 301 is installed with a coaxially arranged and electrically connected clutch upper part 306 and clutch lower part 305. The clutch upper part 306 is connected to the positioning sleeve 28 through a flat key 29. The clutch lower part 305 is positioned through a positioning shaft 304 at the center of the bottom of the clutch support 301 and is fixed to the bottom of the clutch support 301 through a hexagon socket head screw 303. The side wall of the clutch support 301 is fixed with an electrode 302, which is electrically connected to the clutch upper part 306, and the electrode 302 is electrically connected to the controller. The clutch upper part 306 and the clutch lower part 305 are closed when power is on and disengaged when power is off.

[0057] In order to ensure that the clutch lower part 305 and the clutch upper part 306 are correctly closed or disengaged, the coaxiality of the two must be ensured, such as Figure 3 As shown, first, machining must ensure that the coaxiality of the positioning inner hole φ2 of the base plate 6 and the inner hole φ1 of the bearing 6 32 meet the standard, the stopper of the clutch support 301 is tightly matched with the positioning inner hole φ2 of the base plate 6, the positioning shaft 304 is tightly matched with the inner hole of the clutch support 301, and the positioning sleeve 28 is tightly matched with the smooth part of the end of the screw 22, the smooth part of the end of the screw 22 is tightly matched with the inner hole of the bearing 6 32, and the outer circle of the bearing 6 32 is tightly matched with the φ1 hole, so that the coaxiality of the positioning shaft 304 and the outer circle of the positioning sleeve 28 meet the standard, thereby ensuring that the coaxiality of the clutch lower part 305 and the clutch upper part 306 meet the standard, and can be correctly closed or disengaged.

[0058] The motorized assembly 15 is driven by the motor 1507 to drag the worm gear mechanism to drive the nut of the worm wheel and nut combination 33 to rotate. When the worm wheel and nut combination 33 rotates, the screw 22 should be stationary to ensure that the worm wheel and nut combination 33 drives the slider to move up and down. For this purpose, an electromagnetic clutch assembly 30 is required to connect the screw and the bracket. Under normal circumstances, the lower part 305 of the clutch and the upper part 306 of the clutch are disengaged and do not transmit torque. When the motor is lifted and lowered, before the motor is energized, the electromagnetic clutch assembly 30 is energized first, so that the upper and lower parts of the clutch are closed to transmit torque. Since the lower part 305 of the clutch is fixedly connected to the clutch support 301, which is fixedly connected to the bracket, the goal of keeping the screw 22 stationary is achieved. When operated manually, the electromagnetic clutch is disengaged, and the screw 22 is separated from the bracket and moves freely. The handwheel 1018 is connected to the gear mechanism to drive the screw 22 to rotate, and then transmits it to the worm gear and nut combination 33. The worm gear and nut combination 33 is fixedly connected to the inner rings of the two bearings 5 ​​25 through round nuts 6 23. The outer ring of the latter is fixedly connected to the bearing seat 2 35, which is fixedly connected to the slider 4, and the slider 4 is fixedly connected to the ingot seat, and moves up and down with the ingot seat.

[0059] Example 3

[0060] On the basis of Example 2, in order to prevent the lifting movement from exceeding the range and damaging the equipment, a limit switch is set, such as Figure 2 As shown, a striker plate 14 is installed at the bottom of the box 1519, and a travel switch 13 is installed at the upper end surface of the bottom plate 6 directly below the striker plate 14. The travel switch 13 is electrically connected to the controller, and the travel switch 13 and the striker plate 14 are used in conjunction with each other; Figure 4 As shown, a travel switch 38 is vertically installed at the bottom of the top plate 1, and the travel switch 38 is electrically connected to the controller. A collision column 37 is installed at the upper end surface of the slider 4 at a position corresponding to the travel switch 38, and the collision column 37 is used in conjunction with the travel switch 38. When the slider 4 moves to the bottom or top limit position, the collision plate 14 or the collision column 37 squeezes the corresponding travel switch, and the latter triggers the controller to cut off the motor drive circuit and issue a blast warning.

[0061] The utility model has a crystal ingot transporter with a lifting function, and its working principle is as follows: the lifting function is formed by two transmission chains, one for rapid motorization and the other for manual fine-tuning, in parallel. The manual locking is motorized, and the motorized part is powered by an electric motor to drag the worm gear mechanism to drive the worm wheel and nut combination 33 to rotate for rapid lifting and lowering. The manual part is powered by a handwheel 1018 to transmit manpower to drive the lead screw 22 to rotate for fine-tuning. Both of them make the worm wheel and nut combination 33 move up and down with the slider. The guide mechanism adopts a ball linear bearing pair or a ball linear guide pair, and the lifting mechanism adopts a lead screw pair. The worm wheel and nut combination 33 are connected to the slider 4 through bearing five 25. The slider 4 is fixedly connected to the crystal ingot seat and moves vertically up and down along the guide column 8. When the drawn crystal ingot is rotated to a suitable position, the transporter lifting device is required to lift the crystal ingot seat, which is first lifted and lowered rapidly by motorization, and then manually fine-tuned. The transmission chain for rapid lifting is: motor 1507 → coupling 1504 → worm 1518 → worm gear and nut combination 33 → slider 4 → ingot seat; the manual fine-tuning transmission chain is: handle 1001 → handwheel 1018 → tooth-type clutch 1014 → transmission shaft 1019 → small gear 1008 → large gear 18 → lead screw 22 → worm gear and nut combination 33 → slider 4. After the ingot seat is completely attached to the single crystal ingot, the operator releases the ingot or cuts off the seed crystal rod, and the ingot seat receives the single crystal ingot and lowers it to the initial position, and then transports it to the storage location.

[0062] The ingot transporter with lifting function of the utility model has the following advantages: the lowering and transportation of the single crystal ingot are integrated, the operation is simple, and the double V-shaped seat for storing the single crystal ingot can be manually and motorized lifted and lowered. It can cooperate with the crystal retrieval robot to unload the single crystal ingot, and can also work independently to directly move the crystal ingot away, making the unloading and placement of the crystal ingot very flexible and convenient, greatly reducing the burden on workers and reducing operating costs.
