Description

Technical Field

[0001] The present application relates to the field of single crystal pulling, and in particular to a feeding barrel fixing mechanism and a transfer trolley. Background Art

[0002] During the single crystal pulling process, a quartz feeding cylinder is required to re-feed silicon material into the crucible of the single crystal furnace. After the feeding cylinder has finished re-feeding silicon material into the crucible, the feeding cylinder needs to be taken out and fixed vertically on a trolley to facilitate the transportation of the feeding cylinder and the replenishment of silicon material to the emptied feeding cylinder.

[0003] At present, the feeding barrel is generally clamped and fixed on the body of the trolley by a clamp installed on the trolley. The clamping and disassembly of the clamp requires manual operation, which has low efficiency and reduces the feeding efficiency. Utility Model Content

[0004] In order to solve the above technical problems, the present application provides a feeding barrel fixing mechanism, which adopts the following technical solutions:

[0005] A feeding cylinder fixing mechanism comprises a mounting bracket, a driving mechanism and at least one holding component, wherein:

[0006] The holding assembly includes a mounting ring, a toothed disc, n holding blocks, and n transmission parts connecting the toothed disc and the holding blocks, wherein:

[0007] The mounting ring is fixedly mounted on the mounting bracket, and the gear disc is rotatably sleeved on the outer side of the mounting ring;

[0008] The driving mechanism is connected to the gear disc in a transmission manner. The driving mechanism is used to drive the gear disc to rotate. When the gear disc rotates, the n holding blocks are driven to move toward or away from the center of the mounting ring through the n transmission parts to fix or release the feeding barrel passing through the mounting ring.

[0009] n is an integer ≥2.

[0010] The feeding barrel fixing mechanism provided in the present application, after the feeding barrel is inserted into the mounting ring of the holding assembly, the driving mechanism drives the n holding blocks of the holding assembly to move toward the middle to fix the feeding barrel. The driving mechanism drives the n holding blocks of the holding assembly to separate to the surroundings, so that the fixing of the feeding barrel can be released. The feeding barrel fixing mechanism of the present application realizes the automation of the fixing of the feeding barrel. After the feeding barrel fixing mechanism of the present application is installed on the body of the trolley, the trolley can realize the automatic fixing and automatic release of the feeding barrel, thereby improving the feeding efficiency.

[0011] In some embodiments, the transmission part includes a slide rail and a connecting rod. The slide rail extends toward the center of the mounting ring and is fixedly set on the mounting ring; the holding block is slidably set on the slide rail, and the first end of the connecting rod is fixedly connected to the holding block; a guide groove corresponding to the slide rail is set on the gear plate, and the second end of the connecting rod is slidably set in the guide groove.

[0012] When the toothed disc rotates, the inner wall of the guide groove pushes the connecting rod, causing the connecting rod to move in the guide groove, and finally drives the corresponding holding block to slide along the slide rail toward or away from the center of the mounting ring. Through the cooperation of the slide rail, the connecting rod and the guide groove, the holding and releasing movement of the holding block is realized, the transmission is stable, and the synchronization of the holding block movement driven by the same toothed disc is high.

[0013] In some embodiments, n slide rails are circumferentially arranged on the mounting ring, and n guide grooves are circumferentially arranged on the gear disk, and an angle greater than 0° and less than 90° is formed between each guide groove and the corresponding slide rail.

[0014] Since the guide groove and the corresponding slide rail form an angle, when the toothed disc rotates, part of the pushing force from the guide groove side wall on the connecting rod can be transmitted to the holding block in the radial direction, thereby driving the holding block to slide along the slide rail toward or away from the center of the mounting ring. The formation of the angle limits the movement trajectory of the holding block to move toward or away from the center of the mounting ring, with an ingenious design and a simple and compact structure.

[0015] In some embodiments, the second end of the connecting rod is provided with a roller located in the guide groove.

[0016] By arranging a roller at the second end of the connecting rod, the connecting rod can move smoothly in the guide groove after being pressed, thereby preventing the connecting rod from getting stuck during the movement, and further improving the flexibility and efficiency of the clamping or releasing of the holding block.

[0017] In some embodiments, the driving mechanism includes a driving part, a first rotating shaft and at least one first gear, wherein: the first rotating shaft is vertically arranged on the mounting bracket and is transmission-connected to the driving part arranged on the mounting bracket; the first gear is fixedly sleeved on the first rotating shaft and corresponds one-to-one with the holding component, and the first gear is meshed with the corresponding toothed disc of the holding component; the driving part is used to drive the first rotating shaft to rotate to drive the first gear to rotate, and when the first gear rotates, it drives the corresponding toothed disc of the holding component to rotate.

[0018] A driving mechanism with a simple structure and stable driving is provided. A vertically arranged first rotating shaft is meshedly connected with a toothed disc of a holding component via a first gear. When the driving unit drives the first rotating shaft to rotate, the first rotating shaft drives the first gear to rotate, thereby implementing rotational driving of the toothed disc.

[0019] In particular, when multiple holding assemblies are arranged in the vertical direction, the first rotating shaft, driven by the driving part, synchronously drives the toothed disks of multiple holding assemblies to rotate synchronously through multiple first gears, so that the multiple holding assemblies can synchronously fix and release the feeding barrel.

[0020] In some embodiments, the driving unit also includes a support plate, a base, a rack, a second rotating shaft, a second gear, a first bevel gear and a second bevel gear, wherein: the support plate is fixedly arranged at the bottom of the mounting bracket; the base is arranged above the support plate and can move up and down relative to the support plate, the rack is arranged vertically and one end of the rack is fixedly connected to the base; the second rotating shaft is arranged horizontally at the bottom of the support plate, and the second gear is fixedly sleeved on the second rotating shaft and meshed with the rack; the first bevel gear and the second bevel gear are fixedly mounted on the second rotating shaft and the first rotating shaft respectively, and the first bevel gear and the second bevel gear are meshed with each other.

[0021] When the feeding barrel passes through the holding assembly from top to bottom and falls onto the base, the feeding barrel presses down the base, causing the base to move downward. The rack moves downward synchronously with the base, thereby driving the second rotating shaft to rotate through the second gear. When the second rotating shaft rotates, it drives the first bevel gear to rotate synchronously. The first bevel gear drives the first rotating shaft to rotate through the second bevel gear, and finally drives the n holding blocks of the holding assembly to move toward the center of the mounting ring to fix the feeding barrel. It can be seen that by setting the driving part, the present application does not need to set an external driving source such as a motor. The gravity of the feeding barrel itself can trigger the driving part to implement the rotational drive of the first rotating shaft, so as to drive the holding assembly to hold the feeding barrel, thereby reducing equipment costs and energy consumption.

[0022] In some embodiments, the driving unit also includes a vertically arranged guide shaft and an elastic member, the first end of the guide shaft is fixedly connected to the base, the second end of the guide shaft can slide through the support plate, the elastic member is sleeved on the outer periphery of the guide shaft and the two ends of the elastic member are respectively abutted against the base and the support plate.

[0023] By setting the guide shaft, the lifting and lowering guide of the base is realized, and the base is prevented from tilting during the lifting process, which causes the meshing jam between the rack and the second gear. By setting an elastic member on the guide shaft, after the feeding barrel is lifted upward, the elastic member rebounds and stretches, thereby driving the base to move upward. When the base moves upward, the rack moves upward synchronously with the base, thereby driving the second rotating shaft to rotate through the second gear, and the second rotating shaft rotates and drives the first bevel gear to rotate synchronously. The first bevel gear drives the first rotating shaft to rotate through the second bevel gear, and finally drives the n holding blocks of the holding assembly to move away from the center of the mounting ring to release the feeding barrel.

[0024] In some embodiments, the feeding barrel fixing mechanism includes at least two holding components arranged in a vertically spaced relationship, and the feeding barrel passes through the mounting rings of each holding component in sequence from top to bottom.

[0025] More than two holding components cooperate to fix the feeding barrel from different positions, thereby improving the fixing effect of the feeding barrel.

[0026] In some embodiments, when the n holding blocks of the holding assembly fix the feeding barrel, a gap of 1-2 mm is maintained between at least one of the n holding blocks and the feeding barrel.

[0027] Since the holding assembly does not completely clamp the charging barrel, the charging barrel can still be lifted upward when the holding assembly fixes the charging barrel, so that the elastic member gradually rebounds and stretches to push the base to move upward.

[0028] The present application also provides a transfer trolley, which includes a vehicle body and a feeding barrel fixing mechanism as described in any one of the above items, wherein: the mounting bracket of the feeding barrel fixing mechanism can be rotatably set on the vehicle body; the feeding barrel fixing mechanism is used to fix the feeding barrel, and the vehicle body is used to transfer the feeding barrel.

[0029] After the feeding barrel fixing mechanism fixes the feeding barrel on the transfer trolley, when the transfer trolley transfers the feeding barrel to the feeding position, the feeding barrel fixing mechanism can rotate relative to the vehicle body, so that the top feeding port of the feeding barrel is aligned with the dropping port of the feeding device.

[0039] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] like Figure 1 to Figure 2 As shown, the charging barrel fixing mechanism 10 of the present application includes a mounting bracket 1, a driving mechanism 2 and at least one holding component 3, wherein:

[0041] The retaining assembly 3 includes a mounting ring 31 , a toothed disc 32 , n retaining blocks 33 and n transmission parts 34 connecting the toothed disc 32 and the retaining blocks 33 , wherein the mounting ring 31 is fixedly mounted on the mounting bracket 1 , and the toothed disc 32 is rotatably sleeved on the outer side of the mounting ring 31 .

[0042] The driving mechanism 2 is connected to the toothed disc 32 in driving connection. The driving mechanism 2 is used to drive the toothed disc 32 to rotate. When the toothed disc 32 rotates, it drives the n holding blocks 33 to move toward or away from the center of the mounting ring 31 through the n transmission parts 34 to fix or release the feeding barrel passing through the mounting ring 31.

[0043] n is an integer ≥2.

[0044] Figure 1 to Figure 2 The feeding barrel fixing mechanism 10 in the illustrated embodiment includes three holding components 3, and the three holding components 3 are arranged on the mounting bracket 1 at intervals along the vertical direction. Each holding component 3 includes four (i.e., n is 4) holding blocks 33 and four transmission parts 34 connecting the toothed disc 32 and the holding blocks 33. Of course, in other embodiments, one, two, four or other numbers of holding components 3 may also be provided, and each holding component 3 may include two, three, five or other numbers of holding blocks 33 and transmission parts 34.

[0045] When more than two holding components 3 are provided, the feeding barrel 100 passes through the holding rings 31 of each holding component 3 from top to bottom in sequence, and each holding component 3 cooperates with each other to fix the feeding barrel 100 from different positions, thereby improving the fixing effect.

[0046] Combined with reference Figure 1 As shown, the working process of the feeding barrel fixing mechanism 10 in the embodiment of the present application is:

[0047] In the initial state, the n holding blocks 33 of the holding assembly 3 are away from the center of the mounting ring 31 , that is, the n holding blocks 33 are in a state of being separated toward the periphery.

[0048] After the feeding barrel 100 is inserted into the mounting ring 31 of the holding assembly 3 , the driving mechanism 2 drives the n holding blocks 33 of the holding assembly 3 to move toward the middle, and the n holding blocks 33 can cooperate to fix the feeding barrel 100 .

[0049] The driving mechanism 2 drives the n holding blocks 33 of the holding assembly 3 to separate toward the periphery, and the n holding blocks 33 can release the fixation of the feeding barrel 100 .

[0050] The feeding barrel fixing mechanism 10 of the embodiment of the present application realizes the automation of the fixing of the feeding barrel. After the feeding barrel fixing mechanism of the embodiment of the present application is installed on the body of the trolley, the feeding barrel can be automatically fixed and released, thereby improving the feeding efficiency.

[0051] like Figure 1 As shown, optionally, the transmission part 34 includes a slide rail 341 and a connecting rod 342, the slide rail 341 extends toward the center of the mounting ring 31 and is fixedly arranged on the mounting ring 31. The holding block 33 is slidably arranged on the slide rail 341, and the first end of the connecting rod 342 is fixedly connected to the holding block 33. The toothed disc 32 is provided with a guide groove 321 corresponding to the slide rail 341, and the second end of the connecting rod 342 is slidably arranged in the guide groove 321.

[0052] When the toothed disc 32 rotates, the inner wall of the guide groove 321 pushes the connecting rod 342 to push the connecting rod 342 to move in the guide groove 321, thereby driving the corresponding holding block 33 to slide along the slide rail 341 toward or away from the center of the mounting ring 31. For example, when the toothed disc 32 rotates clockwise, the connecting rod 342 drives the corresponding holding block 33 to slide toward the center of the mounting ring 31. When the toothed disc 32 rotates counterclockwise, the connecting rod 342 drives the corresponding holding block 33 to slide away from the center of the mounting ring 31. Through the cooperation of the slide rail 341, the connecting rod 342 and the guide groove 321, the holding and releasing movement of the holding block 33 is realized, the transmission is stable, and the synchronization of the movement of the holding block 33 driven by the same toothed disc is high.

[0053] Continue to refer Figure 1 As shown, optionally, n slide rails 341 are arranged on the mounting ring 31 along the circumferential direction, and n guide grooves 321 are arranged on the toothed disc 32 along the circumferential direction, and an angle greater than 0° and less than 90° is formed between each guide groove 321 and the corresponding slide rail 341, for example, the angle is 30°, 45°, etc. With such arrangement, when the toothed disc 32 rotates, part of the pushing force from the inner wall of the guide groove 321 on the connecting rod 342 can be transmitted to the holding block 33 in the radial direction, thereby ensuring that the holding block 33 slides toward or away from the center of the mounting ring 31 along the slide rail 341. The formation of the angle limits the movement trajectory of the holding block 33 to move toward or away from the center of the mounting ring 31, which is ingenious in design and simple and compact in structure.

[0054] Optionally, the second end of the connecting rod 342 is further provided with a roller located in the guide groove 321. By providing the roller at the second end of the connecting rod 342, the connecting rod 342 can move more smoothly in the guide groove 321 after being pressed, thereby preventing the connecting rod 342 from getting stuck during the movement, thereby further improving the flexibility and efficiency of clamping or releasing of the holding block 33.

[0055] Optionally, the driving mechanism 2 includes a driving portion 21, a first rotating shaft 22 and at least one first gear 23, wherein: the first rotating shaft 22 is vertically arranged on the mounting bracket 1 and is in driving connection with the driving portion 21 arranged on the mounting bracket 1. The first gear 23 is fixedly sleeved on the first rotating shaft 22 and corresponds to the holding component 3 one by one, and the first gear 23 is meshed with the corresponding toothed disc 32 of the holding component 3. The driving portion 21 is used to drive the first rotating shaft 22 to rotate so as to drive the first gear 23 to rotate, and when the first gear 23 rotates, it drives the corresponding toothed disc 32 of the holding component 3 to rotate.

[0056] For example, Figure 1 to Figure 2 The feeding barrel holding mechanism 10 in the illustrated embodiment includes three holding components 3 arranged in the vertical direction, and correspondingly, three first gears 23 are fixedly sleeved on the first rotating shaft 22 and mesh with the toothed discs 32 of the holding components 3 in a one-to-one correspondence. When the driving part 21 drives the first rotating shaft 22 to rotate, the first rotating shaft 22 synchronously drives the toothed discs 32 of the three holding components 3 to rotate through the three first gears 23, so that the three holding components 3 can synchronously fix and release the feeding barrel.

[0057] That is to say, the present application only needs to set up one driving unit 21, and the driving unit 21 can synchronously drive multiple holding components 3 through the first rotating shaft 22, which not only reduces the equipment cost, but also ensures the consistency of the movements of each holding component 3.

[0058] like Figure 2 As shown, optionally, the driving part 21 includes a support plate 211, a base 212, a rack 213, a second rotating shaft 214, a second gear 215, a first bevel gear 216 and a second bevel gear 217, wherein: the support plate 211 is fixedly arranged at the bottom of the mounting bracket 1. The base 212 is arranged above the support plate 211 and can move up and down relative to the support plate 211. The rack 213 is arranged vertically, and one end of the rack 213 is fixedly connected to the base 212. The second rotating shaft 214 is arranged horizontally at the bottom of the support plate 211, and the second gear 215 is fixedly sleeved on the second rotating shaft 214 and meshed with the rack 213. The first bevel gear 216 and the second bevel gear 217 are fixedly installed on the second rotating shaft 214 and the first rotating shaft 22, respectively, and the first bevel gear 216 and the second bevel gear 217 are meshed with each other.

[0059] When the feeding cylinder passes through the holding assembly 3 from top to bottom and falls onto the base 212, the feeding cylinder presses down the base 212, causing the base 212 to move downward. The rack 213 moves downward synchronously with the base 212, thereby driving the second rotating shaft 214 to rotate via the second gear 215. When the second rotating shaft 214 rotates, it drives the first bevel gear 216 to rotate synchronously. The first bevel gear 216 drives the first rotating shaft 22 to rotate (for example, in a clockwise direction) via the second bevel gear 217, and finally drives the n holding blocks 33 of the holding assembly 3 to move toward the center of the mounting ring 31 to fix the feeding cylinder.

[0060] It can be seen that by setting the driving part 21, the present application does not need to set an external driving source such as a motor, and the gravity of the feeding barrel itself can trigger the driving part 21 to implement the rotational drive of the first rotating shaft 22, thereby reducing equipment costs and energy consumption.

[0061] Continue to refer Figure 2 As shown, optionally, the driving part 21 also includes a vertically arranged guide shaft 218 and an elastic member 219, the first end of the guide shaft 218 is fixedly connected to the base 212, the second end of the guide shaft 218 can slide through the support plate 211, the elastic member 219 is sleeved on the outer periphery of the guide shaft 218, and the two ends of the elastic member 219 are respectively abutted against the base 212 and the support plate 211.

[0062] By providing the guide shaft 218 , the lifting and lowering guidance of the base 212 is achieved, thereby preventing the base 212 from tilting during the lifting and lowering process, thereby causing the meshing jam between the rack 213 and the second gear 215 .

[0063] Since the outer periphery of the guide shaft 218 is sleeved with an elastic member 219, when the feeding cylinder presses down the base 212 and the base 212 moves downward, the elastic member 219 is compressed and contracts.

[0064] When the charging barrel is lifted upward, the elastic member 219 rebounds and stretches, thereby driving the base 212 to move upward. The rack 213 moves upward synchronously with the base 212, thereby driving the second rotating shaft 214 to rotate via the second gear 215. When the second rotating shaft 214 rotates, it drives the first bevel gear 216 to rotate synchronously. The first bevel gear 216 drives the first rotating shaft 22 to rotate (for example, rotate counterclockwise) via the second bevel gear 217, and finally drives the n holding blocks 33 of the holding assembly 3 to move away from the center of the mounting ring 31 to release the charging barrel.

[0065] Optionally, when the n holding blocks 33 of the holding assembly 3 fix the charging barrel, a gap of 1-2 mm is maintained between at least one of the n holding blocks 33 and the charging barrel. Since the holding assembly 3 does not completely clamp the charging barrel, the charging barrel can be lifted upward when the holding assembly 3 fixes the charging barrel, so that the elastic member 219 can gradually rebound and stretch to push the base 212 to move upward.

[0066] Figure 2 The driving unit 21 in the embodiment drives the first rotating shaft 22 to rotate, which is triggered by the feeding barrel. When the feeding barrel falls down to press the base 212, the driving unit 21 immediately drives the first rotating shaft 22 to rotate, thereby driving the n holding blocks 33 of the holding assembly 3 to fix the feeding barrel. When the feeding barrel is lifted upward, the driving unit 21 immediately drives the first rotating shaft 22 to rotate in the opposite direction, thereby driving the n holding blocks 33 of the holding assembly 3 to release the feeding barrel. The driving power of the driving unit 21 comes from the gravity of the feeding barrel and the resilience of the elastic member 218, and no additional driving source is required.

[0067] Of course, in other embodiments, an external driving source such as a driving motor may be installed on the mounting frame 1 to drive the first rotating shaft 22 to rotate, thereby driving the holding component 3 to fix and release the feeding barrel.

[0068] like Figure 3 As shown, the embodiment of the present application further provides a transfer vehicle, which includes a vehicle body 20 and a charging barrel fixing mechanism 10 provided in any of the above embodiments, wherein: the mounting bracket 1 of the charging barrel fixing mechanism 10 is rotatably arranged on the vehicle body 20. The charging barrel fixing mechanism 10 is used to fix the charging barrel 100, and the vehicle body 20 is used to transfer the charging barrel 100.

[0069] After the feeding barrel fixing mechanism 10 fixes the feeding barrel 100 on the transfer trolley, when the transfer trolley transfers the feeding barrel to the feeding position, the feeding barrel fixing mechanism 10 can rotate relative to the vehicle body 20, so that the top feeding port of the feeding barrel 100 is aligned with the dropping port of the feeding device.

[0070] By arranging the charging barrel fixing mechanism 10 on the transfer trolley, the trolley can realize automatic fixing and automatic release of the charging barrel, which helps to improve the transfer efficiency of the trolley for the charging barrel.

[0071] Of course, the transfer cart can be a manually propelled cart, or an AGV (Automated Guided Vehicle) cart with a driving source, so as to further realize the automated transfer of the feeding barrel.

[0072] like Figure 1 and Figure 2 As shown, in order to realize the rotational connection between the mounting bracket 1 of the feeding barrel fixing mechanism 10 and the vehicle body 20, optionally, a supporting shaft 4 is provided on the mounting bracket 1, and a sleeve matching the supporting shaft 4 is provided on the vehicle body 20, and the supporting shaft 4 can be rotatably inserted in the sleeve.

It should be understood by those skilled in the art that the description in the embodiments is merely exemplary, and all changes made without departing from the true spirit and scope of the present application should fall within the scope of protection of the present application.
