Description

Technical Field

[0001] This invention relates to the field of silicon rod processing technology, and more particularly to a transport vehicle. Background Technology

[0002] Wire EDM is a processing method that uses a high-speed reciprocating cutting wire to cut the workpiece (such as photovoltaic silicon rods, semiconductors, silicon carbide, sapphire, magnetic materials, etc.).

[0003] Taking silicon rods as an example, in the silicon rod slicing process, after the silicon rod is bonded to the wafer holder with adhesive, the wafer holder with the silicon rod needs to be moved and placed onto the feed fork inside the slicing machine for subsequent cutting. The wafer holder is the structure used to support the silicon rod. However, the wafer holder and silicon rod are quite heavy, and the existing manual moving methods are time-consuming and labor-intensive, and it is difficult to align the wafer holder with the feed fork, resulting in low efficiency in the loading and unloading process of the silicon rod, and also making the silicon rod prone to damage from bumps and knocks.

[0004] Therefore, how to safely and quickly complete the loading and unloading process of silicon rods is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problem, namely, to solve the problem of low loading and unloading efficiency during the processing of parts to be cut.

[0006] The present invention provides a transport vehicle, which includes a vehicle body, a support member, a translation device, and a rotation device. The support member is movably connected to the vehicle body through the translation device and the rotation device. The translation device includes at least a lifting mechanism and a lateral movement mechanism, with the lifting direction of the lifting mechanism and the translation direction of the lateral movement mechanism arranged intersecting each other. The rotation device is connected to the translation device, and the posture of the support member can be changed by adjusting the rotation angle of the rotation device relative to the translation device.

[0007] By adopting the above technical solution, the present invention adjusts the coordinate position of the support in space by means of a translation device and adjusts the placement angle of the support in space by means of a rotation device. This can overcome external factors such as uneven ground or tilted placement of the crystal tray, so that the material fork on the support can dock with the crystal tray on which the silicon rod is installed, and install the crystal tray at a specific position of the wire cutting machine, thereby improving the loading and unloading efficiency of the silicon rod.

[0008] Optionally, the rotating device includes at least one rotation adjustment mechanism, and the rotation axis of the rotation adjustment mechanism is arranged to intersect the vertical direction.

[0009] Optionally, the lifting mechanism includes a vertical guide rail fixedly connected to the vehicle body and a lifting seat slidably connected to the vertical guide rail, and the lateral movement mechanism includes a transverse guide rail fixedly connected to the lifting seat and a lateral movement seat slidably connected to the transverse guide rail.

[0010] Optionally, the rotating device includes a first rotation adjustment mechanism and a second rotation adjustment mechanism. The first rotation adjustment mechanism includes a rotating disk and a first angle adjustment component. The rotating disk is rotatably connected to the transverse sliding seat. The rotation axis of the rotating disk is arranged intersecting the vertical direction. The first angle adjustment component is used to adjust the rotation angle of the rotating disk relative to the transverse sliding seat. The support member is connected to the rotating disk through the second rotation adjustment mechanism.

[0011] With the above technical solution adopted, the present invention can control the support to rotate in two mutually perpendicular vertical planes through the first rotation adjustment mechanism and the second rotation adjustment mechanism, thereby changing the posture of the support and enabling the material fork to dock with the inherent structure on the crystal holder.

[0012] Optionally, the first angle adjustment assembly includes a first lead screw, a first nut, and a connecting rod. The first lead screw is rotatably arranged on the transverse sliding seat about its own axis. The axial direction of the first lead screw is intersected with the rotation axis direction of the rotating disk. The first nut is threadedly engaged with the first lead screw. The first nut is connected to the rotating disk through the connecting rod and transmits driving torque to the rotating disk. The connection position of the connecting rod to the rotating disk is separated from the rotation axis of the rotating disk by a first preset distance. The first nut is slidably arranged relative to the transverse sliding seat through the connecting rod and / or a limiting structure.

[0013] By adopting the above technical solution, the present invention controls the rotation of the rotary disk through a screw and nut structure, thereby enhancing the operability of manual control.

[0014] Optionally, the axis of the first lead screw is arranged perpendicular to the axis of rotation of the rotary disk.

[0015] Optionally, the axis of the first lead screw is arranged perpendicular to the axis of rotation of the rotating disk, one end of the connecting rod is rotatably connected to the first nut and the other end is rotatably connected to the rotating disk, the axis of rotation of both ends of the connecting rod is arranged parallel to the axis of rotation of the rotating disk, and the line connecting the two ends of the connecting rod is arranged intersecting the axis of rotation of the rotating disk.

[0016] Optionally, the edge of the rotating disk is provided with at least one roller, and the transverse seat is provided with a support plate for supporting the roller.

[0017] When the above technical solution is adopted, the load applied to the rotating disk is transferred to the support plate through the rollers, thereby sharing part of the load on the rotating disk and extending the service life of the rotating disk.

[0018] Optionally, the second rotation adjustment mechanism includes a rotating support and a second angle adjustment component. The rotating support is fixedly connected to the support member and is rotatably arranged relative to the rotating disk. The rotation axis direction of the rotating support is intersected with the rotation axis direction of the rotating disk. The second angle adjustment component is used to adjust the rotation angle of the rotating support relative to the rotating disk.

[0019] Optionally, the second angle adjustment assembly includes a drive rod movably arranged between the rotary disk and the rotary support and used to transmit a driving torque to the rotary support.

[0020] With the above technical solution, the rotation of the rotating support relative to the rotating disk can be controlled by the reciprocating movement of the drive rod.

[0021] Optionally, the second angle adjustment assembly further includes a meshing gear and a rack, the rack being fixed to the drive rod, and the gear being rotatably arranged relative to the rotating disk about its own axis.

[0022] With the above technical solution, the present invention can realize the reciprocating movement of the drive rod simply by controlling the rotation of the gear, thus facilitating the selection of the power component. For example, a motor with a rotary drive shaft can meet the requirements.

[0023] Optionally, the second angle adjustment assembly further includes a sprocket drive mechanism for transmitting driving torque to the gear, the sprocket drive mechanism including a drive chain and two sprockets, one of which is coaxially connected to the gear.

[0024] By adopting the above technical solution, the present invention, through the setting of the sprocket transmission mechanism, is more conducive to meeting the needs of spatial arrangement and placing the power component in a suitable position.

[0025] Optionally, the rotation axis of the rotating disk extends horizontally, and the rotation axis of the rotating support is arranged perpendicular to the rotation axis of the rotating disk.

[0026] Optionally, the lifting mechanism includes a lifting hydraulic cylinder for driving the lifting seat to perform lifting movements, and the transverse mechanism includes a second lead screw and a second nut. The second lead screw is rotatably arranged on the lifting seat about its own axis. The axial direction of the second lead screw is parallel to the extension direction of the transverse guide rail. The second nut is threadedly engaged with the second lead screw and is fixedly connected to the transverse seat.

[0027] Optionally, the transport vehicle further includes a fork for cooperating with the support structure of the workpiece to be cut, the fork being fixedly connected to the support or detachably connected to the support.

[0028] Optionally, the lifting mechanism is arranged in a vertical direction, the lateral movement mechanism is arranged in a horizontal direction, and the lateral movement device further includes a push-pull mechanism, which is arranged in a horizontal direction and perpendicular to the lateral movement mechanism.

[0029] As described above, when silicon rods need to be processed, a fork is installed on the support. The transport vehicle is then moved to the worktable carrying the silicon rod and crystal tray. The fork is then aligned with the gripper on the crystal tray by adjusting the translation and rotation devices. The transport vehicle is then manually pushed to push the fork into the gripper of the crystal tray. The silicon rod is then lifted off the worktable by the lifting mechanism. At this point, the silicon rod can be transferred using the transport vehicle. The silicon rod and crystal tray are then moved to the processing equipment by the transport vehicle. The translation and rotation devices are adjusted again to align the crystal tray with the support rail inside the processing equipment. The vehicle is then pushed to feed the silicon rod into the clamp of the processing equipment. The clamp is then used to clamp the silicon rod. The fork is then separated from the crystal tray, and the vehicle is retracted to leave the processing equipment, completing the silicon rod loading process.

[0030] In the above process, the translation device is used to drive the silicon rod to translate within space, and the rotation device is used to drive the silicon rod to rotate within space. At least one rotation adjustment mechanism has its rotation axis arranged intersecting the vertical direction, thereby enabling horizontal adjustment of the silicon rod and crystal holder, effectively overcoming the difficulties in docking caused by uneven ground. Therefore, the transport vehicle provided by this invention not only enables the transfer of silicon rods but also provides positional adjustment functions for the silicon rod and crystal holder in multiple directions and angle adjustment functions for multiple orientations. This allows for more convenient and accurate docking of the fork with the crystal holder and of the crystal holder with the support rails within the processing equipment, thus greatly improving the efficiency of loading and unloading silicon rods.

Detailed Implementation

[0044] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings.

[0046] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0047] The transport vehicle of the present invention is used for loading and unloading workpieces such as photovoltaic silicon rods, semiconductors, silicon carbide, sapphire, and magnetic materials that are to be cut. The transport vehicle of the present invention will be described below using silicon rods as an example.

[0048] Please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of the transport vehicle, silicon rod, and crystal holder in a specific embodiment of the present invention; Figure 2 This is a schematic diagram of the transverse movement mechanism and the first rotation adjustment mechanism in a specific embodiment of the present invention; Figure 3 This is a schematic diagram of the structure of the second rotation adjustment mechanism in a specific embodiment of the present invention.

[0049] Reference Figures 1 to 3 This invention discloses a transport vehicle comprising: a vehicle body 10, a support member 5, a translation device 200, and a rotation device 300. The support member 5 is movably connected to the vehicle body 10 via the translation device 200 and the rotation device 300. The translation device 200 includes at least a lifting mechanism 1 and a lateral movement mechanism 2, with the lifting direction of the lifting mechanism 1 and the translation direction of the lateral movement mechanism 2 arranged intersectingly. In some implementations of this invention, the lifting mechanism 1 moves vertically, and the lateral movement mechanism 2 translates horizontally, with their directions of movement perpendicular to each other, thereby changing the coordinate position of the support member 5 in space.

[0050] The rotating device 300 is connected to the translation device 200. By adjusting the rotation angle of the rotating device 300 relative to the translation device 200, the posture of the support member 5 can be changed. Specifically, after the coordinate position of the support member 5 is adjusted by the translation device 200, the placement angle of the support member 5 in space is adjusted by the rotating device 300 so that the support member 5 can cooperate with the crystal holder containing the silicon rod.

[0051] When silicon rod 8 needs to be processed, a fork 6 is installed on the support 5. The transport vehicle is then moved to the worktable carrying the silicon rod 8 and the crystal holder 7. The crystal holder 7 is the silicon rod support structure used to support the silicon rod 8. Then, by adjusting the translation device 200 and the rotation device 300, the fork 6 is aligned with the gripper plate on the crystal holder 7. The transport vehicle is then manually pushed to push the fork 6 into the gripper plate of the crystal holder 7. Then, the lifting mechanism 1 is used to remove the silicon rod 8 and the crystal holder 7 from the worktable. At this point, the transport vehicle can be used for rotation. The silicon rod 8 and the crystal holder 7 are transported. Then, the silicon rod 8 and the crystal holder 7 are moved to the front of the processing equipment 100 by the transport vehicle. The translation device 200 and the rotation device 300 are adjusted again to align the crystal holder 7 with the support slide rail 101 in the processing equipment 100. The vehicle body 10 is pushed to feed the silicon rod 8 into the clamp of the processing equipment 100. At this time, the silicon rod 8 is clamped by the clamp, and then the feed fork 6 is separated from the crystal holder 7. The vehicle body 10 is then moved back to the processing equipment 100 to complete the loading process of the silicon rod 8.

[0052] When the silicon rod 8 is finished and needs to be unloaded, the transport vehicle is moved to one side of the processing equipment 100. By adjusting the translation device 200 and the rotation device 300, the fork 6 is aligned with the gripper of the crystal tray 7. The vehicle body 10 is pushed forward to insert the fork 6 into the crystal tray 7. Then, the clamp of the processing equipment 100 is released, so that the crystal tray 7 is transferred to the transport vehicle. Finally, the transport vehicle is pushed out to realize the unloading.

[0053] It should be noted that the crystal holder 7 used in this solution is a silicon rod support structure used to support the silicon rod 8. The crystal holder 7 is usually bonded and fixed above the silicon rod 8. The crystal holder 7 and the silicon rod 8 can be transferred by inserting the fork 6 into the gripper plate of the crystal holder 7.

[0054] In the above process, the translation device 200 is used to drive the silicon rod 8 to translate in space, and the rotation device 300 is used to drive the silicon rod 8 to rotate in space. At least one rotation adjustment mechanism has its rotation axis arranged intersecting the vertical direction, thereby enabling the horizontal adjustment of the silicon rod 8 and the crystal holder 7, effectively overcoming the difficulties in docking caused by uneven ground. It is evident that the transport vehicle provided by this invention can not only transfer the silicon rod 8, but also achieve position adjustment functions in multiple directions and angle adjustment functions in multiple postures for the silicon rod 8 and the crystal holder 7. This allows for more convenient and accurate docking of the fork 6 with the crystal holder 7 and of the crystal holder 7 with the support slide rail 101 within the processing equipment 100, thereby greatly improving the loading and unloading efficiency of the silicon rod 8.

[0055] It should be noted that the support member 5 in this invention is movably connected to the vehicle body 10 via a translation device 200 and a rotation device 300. Therefore, the combined action of the translation device 200 and the rotation device 300 determines the specific movement form of the support member 5. The translation device 200 includes at least a lifting mechanism 1 and a lateral movement mechanism 2; that is, the translation device 200 may also include other translation adjustment mechanisms besides the lifting mechanism 1 and the lateral movement mechanism 2. Therefore, the translation device 200 of this invention can achieve translational movement control in two or more directions. The rotation device 300 includes rotation adjustment mechanisms arranged intersectingly in at least two rotation axis directions. Therefore, the rotation device 300 of this invention can achieve rotational movement control around two or more rotation axis directions respectively. Furthermore, the arrangement order and combination of the various translation adjustment mechanisms and rotation adjustment mechanisms on the vehicle body 10 in this invention can be selected in various ways. For example, first, the translation device 200 is installed on the vehicle body 10 and the various translation adjustment mechanisms are connected sequentially. Then, the rotation device 300 is installed at the moving end of the last translation adjustment mechanism and the various rotation adjustment mechanisms are connected sequentially. Finally, the support member 5 is connected to the moving end of the last rotation adjustment mechanism. With this arrangement, moving each translation adjustment mechanism individually can drive the translation adjustment mechanisms after its moving end and all rotation adjustment mechanisms to translate together. Rotating each rotation adjustment mechanism individually can drive the rotation adjustment mechanisms after its moving end to rotate together, thereby realizing the translation and rotation movement of the last support member 5. Alternatively, the present invention can first install the rotation device 300 on the vehicle body 10 and connect the various rotation adjustment mechanisms sequentially. Then, the translation device 200 is installed at the moving end of the last rotation adjustment mechanism and the various translation adjustment mechanisms are connected sequentially. Finally, the support member 5 is connected to the moving end of the last translation adjustment mechanism. Of course, the present invention can also connect the various translation adjustment mechanisms and the various rotation adjustment mechanisms in other sequences, which can also realize the translation and rotation of the last support member 5. Those skilled in the art can design the arrangement of the above-mentioned translation device 200 and rotation device 300 and the connection relationship between the various mechanisms according to the specific application requirements of the transport vehicle. The specific implementation process of each movement will not be listed in detail here.

[0056] In one specific implementation plan, please refer to Figures 1 to 3The lifting mechanism 1 includes a vertical guide rail 12 fixedly connected to the vehicle body 10 and a lifting seat 11 slidably connected to the vertical guide rail 12. The transverse movement mechanism 2 includes a transverse guide rail 24 fixedly connected to the lifting seat 11 and a transverse movement seat 21 slidably connected to the transverse guide rail 24. The rotating device 300 includes a first rotation adjustment mechanism 3 and a second rotation adjustment mechanism 4. The first rotation adjustment mechanism 3 includes a rotating disk 31 and a first angle adjustment component. The rotating disk 31 is rotatably connected to the transverse movement seat 21. The rotation axis of the rotating disk 31 is arranged intersecting the vertical direction. The first angle adjustment component is used to adjust the rotation angle of the rotating disk 31 relative to the transverse movement seat 21. The support member 5 is connected to the rotating disk 31 through the second rotation adjustment mechanism 4. The second rotation adjustment mechanism 4 is used to drive the support member 5 to further adjust the rotation angle relative to the rotating disk 31. The vertical guide rail 12 can extend in the vertical direction or form an acute angle with the vertical direction; the transverse guide rail 24 can extend in the horizontal direction or form an acute angle with the horizontal direction. The lifting mechanism 1 can adjust the height of the support member 5, and the horizontal movement mechanism 2 can adjust the horizontal position of the support member 5. In this scheme, the tilt angle of the support member 5 relative to the horizontal direction is mainly adjusted by the first rotation adjustment mechanism 3. The rotating disk 31 serves as the moving end of the first rotation adjustment mechanism 3, which can drive the second rotation adjustment mechanism 4 and the support member 5 to rotate together.

[0057] It is understandable that the first rotation adjustment mechanism 3 and the second rotation adjustment mechanism 4 can respectively control the support member 5 to rotate in two mutually perpendicular vertical planes, thereby changing the posture of the support member 4 so that the material fork can dock with the inherent structure on the crystal holder.

[0058] It should be noted that the first angle adjustment component used to adjust the rotation angle of the rotating disk 31 described above can have multiple implementations. In one specific embodiment, the first angle adjustment component includes a first lead screw 34, a first nut 35, and a connecting rod 36. The first lead screw 34 is rotatably arranged on the transverse seat 21 around its own axis. The axial direction of the first lead screw 34 is intersected with the rotation axis of the rotating disk 31. The first nut 35 is threadedly engaged with the first lead screw 34. The first nut 35 is connected to the rotating disk 31 through the connecting rod 36 and transmits driving torque to the rotating disk 31. The connection position of the connecting rod 36 and the rotating disk 31 is separated from the rotation axis of the rotating disk 31 by a first preset distance. This first preset distance is determined according to the specific size of the rotating disk 31. Its purpose is to enable the rotating disk 31 to rotate when the connecting rod 36 swings. The first nut 35 is slidably arranged relative to the transverse seat 21 through the connecting rod 36 and / or the limiting structure. The connecting rod 36 and / or the limiting structure restrict the rotational movement of the first nut 35 relative to the transverse sliding seat 21. Thus, when the first lead screw 34 rotates relative to the transverse sliding seat 21, only the first nut 35 is allowed to slide relative to the transverse sliding seat 21. This allows the first nut 35 to drive the connecting rod 36 to rotate the rotating disk 31. The limiting structure can be designed as a limiting plate or limiting groove fixed to the transverse sliding seat 21 and arranged parallel to the first lead screw 34. Simultaneously, a portion of the outer circumferential surface of the first nut 35 is attached to the surface of the limiting structure. The contact surface is a plane or a non-cylindrical curved surface, thereby restricting the rotational movement of the first nut 35 around its own axis. This solution can also use the connecting rod 36 alone to restrict the rotation of the first nut 35. Specifically, when the two ends of the connecting rod 36 are hinged to the first nut 35 and the rotating disk 31 respectively, and the hinge axis of the connecting rod 36 and the first nut 35 is designed to be non-coaxial with the axis of the first nut 35 (i.e., cross-arranged or parallel arrangement), the rotational movement of the first nut 35 around its own axis can be restricted. In addition, to facilitate manual driving of the first lead screw 34, this solution also has a first lead screw handle 33 fixed to the end of the first lead screw 34 for easy manual operation, such as... Figure 2 As shown.

[0059] The working process of the first angle adjustment component in the above embodiment is as follows: When the first lead screw 34 rotates relative to the transverse seat 21, the first nut 35 is restricted from rotation by the connecting rod 36 and / or the limiting structure. Therefore, as the first lead screw 34 rotates, the first nut 35 slides along the axial direction of the first lead screw 34, thereby driving the connecting rod 36 to move its position. The connecting rod 36 then transmits the force to the rotating disk 31, thereby applying a driving torque to the rotating disk 31. The rotating disk 31 rotates accordingly, thereby driving the second rotation adjustment mechanism 4 and the support member 5 to rotate together.

[0060] More preferably, such as Figure 2As shown, the axis of the first lead screw 34 is arranged perpendicular to the axis of rotation of the rotating disk 31. One end of the connecting rod 36 is rotatably connected to the first nut 35, and the other end is rotatably connected to the rotating disk 31. The axes of rotation at both ends of the connecting rod 36 are arranged parallel to the axis of rotation of the rotating disk 31 to ensure that the connecting rod 36 can swing along with the movement of the first nut 35. The line connecting the two ends of the connecting rod 36 intersects the axis of rotation of the rotating disk 31 to ensure that the connecting rod 36 can drive the rotating disk 31 to rotate during the swinging process. With this configuration, the connecting rod 36 and the first nut 35 form a crank-slider mechanism. To level, rotating the first lead screw 34 causes the first nut 35 to move along the first lead screw 34, thereby causing the connecting rod 36 to swing, which in turn causes the rotating disk 31 to rotate. The rotating disk 31 then drives the second rotation adjustment mechanism 4 and the support member 5 to rotate together, achieving the purpose of leveling.

[0061] Preferably, the edge of the rotating disk 31 is provided with at least one roller 32, and the transverse seat 21 is provided with an arc-shaped support plate 25 for supporting the roller 32. When the rotation axis of the rotating disk 31 is arranged in the horizontal direction, the second rotation adjustment mechanism 4 and the support member 5 connected to the rotating disk 31 are similar to a cantilever beam structure, and the force applied to the rotating disk 31 is relatively large. When the support member 5 carries a load such as a silicon rod 8, the load on the rotating disk 31 is even greater. This solution can share part of the load on the rotating disk 31 by setting the roller 32 and the arc-shaped support plate 25, thereby extending the service life of the rotating disk 31.

[0062] Specifically, the edge of the rotating disk 31 is fixed with a bracket for mounting the roller 32. The bracket is fixedly connected to the rotating disk 41, and the roller 32 is rotatably connected to the bracket, so that when the rotating disk 31 rotates, the roller 32 can roll along the arc-shaped support plate 25 to reduce the resistance of the rotating disk 31.

[0063] It should be noted that the second rotation adjustment mechanism 4 is used to drive the support member 5 to rotate relative to the rotating disk 31. It can be implemented in various ways, for example, by using a cylinder or hydraulic cylinder to drive a telescopic rod to rotate the support base carrying the support member 5 relative to the rotating disk 31; or by using a motor and a reduction mechanism to drive the support base carrying the support member 5 relative to the rotating disk 31; or by manually adjusting the rotation, etc. Preferably, the second rotation adjustment mechanism 4 in this solution includes a rotating support 41 and a second angle adjustment assembly. The rotating support 41 is fixedly connected to the support member 5 and rotatably arranged relative to the rotating disk 31. Figure 3As shown, the end of the rotating support 41 is provided with a rotating shaft 43 for hinged to the rotating disk 31. The rotation axis direction of the rotating support 41 (i.e. the axis direction of the rotating shaft 43) is arranged to intersect with the rotation axis direction of the rotating disk 31. The second angle adjustment component is used to adjust the rotation angle of the rotating support 41 relative to the rotating disk 31.

[0064] It should be noted that the aforementioned second angle adjustment component can be implemented in various ways, such as being directly driven to rotate by a stepper motor, or being driven to rotate by the telescopic rod of a pneumatic or hydraulic cylinder, etc. Preferably, as shown below... Figure 3 As shown, the second angle adjustment component in this solution includes a drive rod 44, which is movably arranged between the rotating disk 31 and the rotating support 41 and is used to transmit driving torque to the rotating support 41. In another preferred embodiment, the second angle adjustment component includes a telescopic rod with adjustable length. One end of the telescopic rod is fixed relative to the rotating disk 31 and is a second preset distance away from the rotation axis of the rotating support 41. The other end of the telescopic rod is connected to the rotating support 41 and is a third preset distance away from the rotation axis of the rotating support 41. With this configuration, the line connecting the two ends of the telescopic rod and the rotation center of the rotating support 41 forms a triangular structure. By changing the length of the telescopic rod, the rotation angle of the rotating support 41 relative to the rotating disk 31 can be changed. The telescopic rod can be a pneumatic telescopic rod or a hydraulic telescopic rod, etc. In one specific embodiment, the telescopic rod is a pneumatic telescopic rod. The fixed end of the pneumatic telescopic rod is hinged to the fixed frame 42 fixed to the rotating disk 31, and the second preset distance is 0.8 times the length of the rotating support 41. The movable end of the pneumatic telescopic rod is hinged to the rotating support 41, and the third preset distance is 0.5 times the length of the rotating support 41. The length of the pneumatic telescopic rod is greater than 0.3 times the length of the rotating support 41 and less than 1.3 times the length of the rotating support 41. The rotation angle of the rotating support 41 relative to the rotating disk 31 can be controlled by adjusting the length of the pneumatic telescopic rod.

[0065] Preferably, the second angle adjustment assembly further includes a meshing gear 45 and a rack, with the rack fixedly connected to the drive rod 44, and the gear 45 arranged to rotate relative to the rotating disk 31 around its own axis. By rotating the gear 45, the rack and drive rod 44 can be driven to move back and forth, thereby controlling the rotation of the rotating support 41 relative to the rotating disk 31.

[0066] Preferably, the second angle adjustment assembly further includes a sprocket drive mechanism for transmitting driving torque to the gear 45. The sprocket drive mechanism includes a drive chain 48 and two sprockets, one of which is coaxially connected to the gear 45. Figure 3As shown, the sprocket drive mechanism includes a drive chain 48, a first sprocket 46, and a second sprocket 47. The first sprocket 46 serves as the driving sprocket, and the second sprocket 47 serves as the driven sprocket. The second sprocket 47 is coaxially connected to a gear 45. Driving the first sprocket 46 drives the second sprocket 47 and the gear 45 to rotate via the drive chain 48, thereby driving the rack and drive rod 44 to reciprocate, and thus controlling the rotation of the rotating support 41 relative to the rotating disk 31. To facilitate the arrangement of the sprocket drive mechanism and the gear 45, rack, and drive rod 44, this design also includes a fixed frame 42 fixedly connected to the rotating disk 31, such as... Figure 3 As shown. To facilitate manual rotation of the first sprocket 46, this design also includes a sprocket handle 49 coaxially fixed to one side of the first sprocket 46, as shown. Figure 3 As shown.

[0067] It should be noted that the second angle adjustment component is not limited to the gear and rack configuration described above. For example, in other embodiments of the present invention, the second angle adjustment component can also be a worm gear, where the rotation of the worm gear drives the worm to reciprocate, achieving the same objective. Similarly, the sprocket drive mechanism described above can be replaced with, for example, a synchronous belt drive mechanism. Therefore, any modifications or substitutions made to its specific form without departing from the principle of the present invention are within the scope of protection of the present invention.

[0068] It should be noted that the rotation axis of at least one of the rotation adjustment mechanisms in this invention is arranged intersecting the vertical direction. Specifically, it can be arranged at an angle relative to the vertical direction or perpendicular to the vertical direction. Preferably, the rotation axis of the rotating disk 31 in this solution extends horizontally, and the rotation axis of the rotating support 41 is arranged perpendicular to the rotation axis of the rotating disk 31. With this arrangement, since the rotating disk 31 is rotatably connected to the transverse sliding seat 21, the rotation axis of the rotating disk 31 remains unchanged, and the rotational movement of the rotating disk 31 can realize the leveling function of the support 5. The rotating support 41 is arranged to rotate relative to the rotating disk 31, so the rotation axis of the rotating support 41 is affected by the rotation angle of the rotating disk 31. That is, the rotation axis of the rotating support 41 can extend horizontally or vertically, or it can be arranged at an angle relative to the horizontal direction. In practical applications, the pitch angle adjustment function of the support 5 can be realized through the combined movement of the rotating disk 31 and the rotating support 41.

[0069] It should be noted that the lifting mechanism 1 in this invention is used to control the lifting movement of the support member 5, and the lateral movement mechanism 2 is used to control the translational movement of the support member 5 in another direction. The lifting mechanism 1 can be implemented in various ways, such as a hydraulic lifting mechanism, a motor-driven lifting mechanism, a manual lifting mechanism, etc. The lateral movement mechanism 2 can also be implemented in various ways, such as a manually driven ball screw lateral movement mechanism, a gear and rack lateral movement mechanism, a cylinder or hydraulic cylinder telescopic rod lateral movement mechanism, etc. Preferably, as... Figure 5 As shown, the lifting mechanism 1 in this scheme includes a lifting hydraulic cylinder 13 for driving the lifting seat 11 to move up and down. The vertical guide rail 12 is used to guide the sliding direction of the lifting seat 11. The transverse mechanism 2 includes a second lead screw 22 and a second nut. The second lead screw 22 is rotatably arranged on the lifting seat 11 around its own axis. The axis of the second lead screw 22 is parallel to the extension direction of the transverse guide rail 24. The second nut is threadedly engaged with the second lead screw 22 and is fixedly connected to the transverse seat 21. When it is necessary to adjust the height of the support member 5, the lifting hydraulic cylinder 13 is activated to drive the lifting seat 11 to move along the vertical guide rail 12, which can drive the transverse mechanism 2, the rotating device 300, and the support member 5 to achieve lifting and lowering adjustment. When it is necessary to adjust the transverse displacement of the support member 5, the second lead screw 22 can be manually rotated. Since the second lead screw 22 is rotatably arranged on the lifting seat 11, the second nut can be driven to move along the transverse guide rail 24 together with the transverse seat 21, thereby driving the rotating device 300 and the support member 5 to achieve translation adjustment. In addition, to facilitate manual rotation of the second lead screw 22, a second lead screw handle 23 is fixedly connected to the end of the second lead screw 22. The second lead screw 22 can be rotated by manually cranking the second lead screw handle 23.

[0070] It should be noted that the transport vehicle provided by this invention can be applied to various applications, realizing functions such as lifting, translating, leveling, and tilting adjustment of the transported object. Specifically, in the field of silicon rod processing technology, the transport vehicle provided by this invention also includes a fork 6 for cooperating with the silicon rod bearing structure. The fork 6 is fixedly connected to the support member 5 or detachably connected to the support member 5. When it is necessary to transfer the silicon rod 8, the silicon rod 8 is first fixedly connected to the silicon rod bearing structure, and then the fork 6 of the transport vehicle is used to lift the silicon rod bearing structure, thereby realizing the transfer and position adjustment of the silicon rod 8.

[0071] More preferably, the vehicle body 10 of the transport vehicle provided in this solution is also equipped with a water receiving tray 9 located below the forks 6, such as... Figure 1 As shown, it is used to collect water droplets falling from silicon rod 8, thereby keeping the working environment dry and clean.

[0072] To further facilitate the movement of the vehicle body 10, preferably, this design also includes multiple wheels 14 located beneath the vehicle body 10, such as... Figure 1 As shown.

[0073] In a preferred embodiment, the lifting mechanism 1 is arranged vertically, the lateral movement mechanism 2 is arranged horizontally, and the translation device 200 further includes a push-pull mechanism (not shown in the figure), which is arranged horizontally and perpendicular to the translation direction of the lateral movement mechanism 2. Specifically, in this embodiment, the lateral guide rail 24 of the lateral movement mechanism 2 can be arranged along the left-right direction of the vehicle body 10. In this case, the translation direction of the push-pull mechanism is arranged along the front-back direction of the vehicle body 10. When the vehicle body 10 of the vehicle moves to near the target position, the front-back position of the support member 5 can be further precisely adjusted through the push-pull mechanism.

[0074] Below, in conjunction with Figures 4 to 10 The following is a detailed description of the working process of the transport vehicle providing this invention, which drives the silicon rod 8 to feed the material:

[0075] like Figure 4 As shown, the silicon rod 8 is bonded and fixed below the crystal holder 7, which is the silicon rod support structure. The crystal holder 7 is usually designed with a gripping plate or support hole for the feed fork 6 to pass through, so that the feed fork 6 can lift the crystal holder 7 and the silicon rod 8 together. Figure 5 As shown, when silicon rod 8 needs to be loaded, a fork 6 is installed on the support 5. The transport vehicle is then moved to the workbench carrying silicon rod 8 and crystal tray 7. The height of the support 5 and fork 6 is adjusted by the lifting mechanism 1, the horizontal displacement of the support 5 and fork 6 is adjusted by the traversing mechanism 2, the leveling of the support 5 and fork 6 is achieved by the first rotation adjustment mechanism 3, and the pitch angle adjustment of the support 5 and fork 6 is achieved by the second rotation adjustment mechanism 4. This aligns the fork 6 with the gripping plate or bearing hole on the crystal tray 7. The transport vehicle body 10 is then manually pushed to insert the fork 6 into the gripping plate or bearing hole of the crystal tray 7. Then, the lifting mechanism 1 is activated to raise the silicon rod 8 and crystal tray 7 (e.g., ...). Figure 5 (As indicated by the arrow) and detached from the worktable, the silicon rod 8 and crystal holder 7 can then be transferred using a transport vehicle, as shown in the image. Figure 6 As shown, make the transport vehicle move along Figure 6 The silicon rod 8 is moved in the direction of the arrow to transfer it, and then the silicon rod 8 and the crystal holder 7 are transferred to the vicinity of the processing equipment 100 (e.g., ...). Figure 7 As shown). Figure 8As shown, the lifting mechanism 1 is adjusted again to align the height of the crystal tray 7 with the support slide rail 101 of the processing equipment 100, and the horizontal movement mechanism 2 is adjusted to align the horizontal position of the crystal tray 7 with the support slide rail 101. Then, the first lead screw 34 is driven to rotate by manually rotating the first lead screw handle 33, thereby moving the first nut 35 and the connecting rod 36, which in turn drives the rotating disk 31 to rotate, thus achieving the leveling of the crystal tray 7 and silicon rod 8 along the left and right directions of the vehicle body 10. Then, the sprocket handle 49 is manually rotated to drive the gear 45 to rotate, thereby causing the rotating support 41 to rotate relative to the rotating disk 31 by a certain angle, thus achieving the pitch adjustment of the crystal tray 7 and silicon rod 8 along the front and rear directions of the vehicle body 10. At this time, the bearing structure of the crystal tray 7 is aligned and parallel with the support slide rail 101. The crystal tray 7 can be slid into the support slide rail 101 by continuing to push the vehicle body 10 or by adjusting the push-pull mechanism. Correspondingly, the silicon rod 8 is also pushed into place, and the silicon rod 8 can be clamped using a clamp. Figure 9 As shown. Finally, pull the vehicle body 10 backward to separate the fork 6 from the crystal holder 7, as shown. Figure 10 As shown, the retracted vehicle body 10 is removed from the processing equipment 100, thus completing the loading process of the silicon rod 8.

Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
