Description

Technical Field

[0001] The present invention relates to the field of material processing equipment, and in particular to a rotating loading platform and a control method thereof, and a crystal rod processing system. Background Art

[0002] At present, crystalline silicon solar cells are widely used in the field of photovoltaic power generation due to their high conversion efficiency. Crystalline silicon solar cells are made on high-quality silicon wafers, which are made from pulled or cast silicon rods through a series of processing steps such as wire saw cutting. The existing crystal rod processing system is generally single-station or double-station processing, with low processing efficiency and low production capacity, which cannot meet the needs of cost reduction and efficiency improvement.

[0003] Designing a multi-station crystal rod processing system will face many technical problems. For example, when loading materials in the existing crystal rod processing system, the delivery device delivers the crystal rod from the previous processing system or the raw material warehouse to the transfer device of the current crystal rod processing system, and the transfer device then transfers the crystal rod to the processing station. This operation method can usually only deliver one crystal rod at a time, and after one processing is completed, it is necessary to wait for the unloading to be completed before radial loading. This loading and unloading method will affect the processing efficiency of the multi-station crystal rod processing system because the loading time is too long. Summary of the invention

[0004] The purpose of the present invention is to provide a rotating loading platform and a control method thereof, and a crystal rod processing system, so as to solve the problem that the loading and unloading time of the crystal rod processing system is too long.

The effective clamping surface of the pad and / or pressure plate and the crystal rod is smaller than the end surface of the crystal rod to reserve a receiving space when taking and placing the crystal rod from the axial end surface of the crystal rod.

[0009] Furthermore, a preset contact area is left between the pad and the effective clamping surface of the crystal rod compared to the two sides or the middle of the lower end surface of the crystal rod to reserve a supporting space; a preset contact area is left between the pressure plate and the effective clamping surface of the crystal rod compared to the two sides or the middle of the upper end surface of the crystal rod to reserve a clamping space.

[0042] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0043] The rotating loading table 2 provided in the embodiment of the present invention is specifically used to cooperate with the crystal rod handling device to realize the loading and unloading of the crystal rod processing system. When the crystal rod processing system can process multiple crystal rods at the same time (that is, the crystal rod processing system has at least two crystal rod processing stations), the rotating loading table 2 can clamp multiple crystal rods at the same time to quickly provide the crystal rod processing system with crystal rods to be processed, and can temporarily store the processed crystal rods, thereby reducing the waiting time for loading and unloading the crystal rods when the crystal rod processing system is working, effectively shortening the time rhythm of loading and unloading the crystal rods, and the overall structure of the rotating loading table is compact, which saves space and reduces the floor space occupied.

[0044] It should be noted that, in a specific embodiment of the present invention, the rotating loading platform 2 cooperates with the flipping platform 1 at the front end and the crystal rod transfer device at the rear end (not shown in the drawings) to jointly realize the loading and unloading of the crystal rod of the crystal rod processing system. Specifically, when loading, the flipping platform 1 flips the crystal rod from a flat state to a vertical state, and delivers the vertical crystal rod to the rotating loading platform 2. The rotating loading platform 2 carries the crystal rod to be processed and rotates to the crystal rod transfer device. The crystal rod transfer device clamps the crystal rod to be processed and then sends it to the processing station of the crystal rod processing system. When unloading, the crystal rod transfer device clamps the processed crystal rod and moves to the rotating loading platform 2, transfers the processed crystal rod to the rotating loading platform 2, and the rotating loading platform 2 carries the processed crystal rod and rotates to the flipping platform 1. The flipping platform 1 clamps the processed crystal rod and flips the processed crystal rod from a vertical state to a flat state, realizing the final unloading of the processed crystal rod. This operation flow only schematically illustrates the single process of loading and unloading of the crystal rod. In actual operation, it is necessary to set a specific loading and unloading operation flow in conjunction with the actual operation.

[0045] A crystal rod transfer device is also provided on one side of the rotating loading platform 2 of the embodiment of the present invention. The crystal rod transfer device can move between the rotating loading platform and multiple crystal rod processing stations of the crystal rod processing system to transport the crystal rod to be processed from the loading clamping device on the rotating loading platform to the crystal rod processing station, and / or to transport the processed crystal rod from the crystal rod processing station to the loading clamping device on the rotating loading platform. The crystal rod transfer device of the embodiment of the present invention can be provided with two clamping claw assemblies at the same time, which are used to clamp the crystal rod to be processed and the processed crystal rod respectively, so as to realize the loading and unloading of the crystal rod at the same time in the process of one transfer, thereby shortening the loading and unloading time of the crystal rod.

[0046] like Figure 1 , Figure 2 and Figure 3As shown, the rotary loading platform 2 provided in the embodiment of the present invention includes a rotary loading unit 21, an electrical unit 22 and a water receiving unit 23. The functions and specific structures of each unit module of the rotary loading platform 2 in the embodiment of the present invention are introduced in detail below.

[0047] The rotating loading unit 21 can rotate on the rotating loading platform 2. A plurality of crystal rod clamping stations are arranged on the rotating loading unit 21. Each crystal rod clamping station is provided with a loading clamping device 213 for providing or receiving the crystal rod. The position of different crystal rod clamping stations is switched by controlling the rotation of the rotating loading unit 21, so as to take or place the crystal rod from each crystal rod clamping station.

[0048] The electrical unit 22 includes an electrical fixed part 221 and an electrical rotating part 222. The electrical fixed part 221 is connected to an external energy input device, and the electrical rotating part 222 is fixedly arranged on the rotating loading unit 21 and can rotate with the rotating loading unit 21. The electrical fixed part 221 is connected to the electrical rotating part 222 through a slip ring assembly 223, and the electrical rotating part 222 is connected to the electrical equipment in the rotating loading unit 21 through an electrical line to provide energy power for the electrical equipment in the rotating loading unit 21.

[0049] Furthermore, the external energy specifically includes an air source of a pneumatic device and a power source of an electric device. The pneumatic device specifically can be a cylinder, and the electric device specifically can be an electrical component such as a motor, a sensor, a processor, etc. Since there is no relative motion between the electrical rotating part 222 and the rotating material loading unit 21, the line winding problem caused by the rotation of the rotating material loading unit 21 is avoided.

[0050] The water receiving unit 23 is arranged below the rotating material loading unit 21 of the rotating material loading platform 2, and a rotating driving unit 24 is arranged below the water receiving unit 23. The water receiving unit 23 is used to receive water stains flowing down from the rotating material loading unit 21 to prevent the water stains from splashing onto the rotating driving unit 24, and also to prevent the water stains from flowing into the ground and causing water accumulation on the ground. The present invention improves the stability and safety of the equipment operation by arranging the water receiving unit 23.

[0051] Furthermore, the rotary loading platform 2 of the embodiment of the present invention further comprises a turntable frame 25 fixedly connected to the rotary loading platform base, and a rotary driving unit 24 is mounted on the turntable frame 25 for driving the rotary loading unit 21 to rotate.

[0052] In a specific embodiment of the present invention, the rotary drive unit 24 specifically includes a rotary servo motor 241, a rotary reducer 242, a rotary bearing 243 and a connecting plate 244. The rotary servo motor 241 is connected to the rotary reducer 242 and fixed on the turntable frame 25. The inner ring of the rotary bearing 243 is fixedly connected to the turntable frame 25, and the outer ring of the rotary bearing 243 is respectively connected to the rotary reducer 242 and the rotary loading unit 21. The outer ring of the rotary bearing 243 is connected to the rotary loading unit 21 through the connecting plate 244. Driven by the rotary servo motor 241, the connecting plate 244 rotates with the rotating shaft of the rotary drive unit 24, and the rotary loading unit 21 is also fixedly connected to the connecting plate 244, so as to drive the entire rotary loading unit 21 to rotate through the connecting plate 244. The rotary bearing 243 of the embodiment of the present invention can be a cross roller bearing, so as to improve the control accuracy of the rotation angle. Of course, the rotary bearing 243 of the embodiment of the present invention can also select other bearing structures.

[0053] In addition, since the rotary drive unit 24 and the rotary loading unit 21 are in a state of relative motion, the power supply of the rotary drive unit 24 is different from that provided by the electrical unit 22 in the above embodiment, but is provided by connecting an external power source separately, thereby reducing the complexity of the structure of the electrical unit 22. In specific applications, the power supply form of the rotary drive unit 24 can be selected according to actual needs and structural space limitations.

[0054] Furthermore, the rotary loading unit 21 of the embodiment of the present invention specifically includes a turntable 211 and a plurality of loading clamping devices 213 disposed on the turntable 211, and the loading clamping device 213 corresponds to a crystal rod clamping station for clamping the crystal rod. The loading clamping device 213 is disposed perpendicular to the turntable 211 to clamp the crystal rod in a vertical posture, and the loading clamping device 213 is distributed at different positions around the turntable 211, which makes full use of the spatial structure, makes the rotary loading unit 21 compact, and facilitates the cooperation with other equipment to realize the rapid and stable placement of the crystal rod.

[0055] Further, the turntable 211 includes at least two turntable side arms 2111 radiating outward from the center of the turntable 211. One end of each turntable side arm 2111 is connected to each other at the center of the turntable 211, and is rotatably connected to the rotation drive unit 24 through a connecting plate. A loading support column 212 is vertically arranged on each turntable side arm 2111, and a loading clamping device 213 is arranged on the loading support column 212. One end of the loading support column 212 is fixedly connected to the turntable 211, and the other end extends vertically upward. The loading support column 212 can provide vertical support for the loading clamping device 213. Two loading clamping devices 213 can be arranged on the side arm of each loading support column 212 at the same time to make full use of the structural space of the rotating loading unit 21. The rotation of the turntable 211 is controlled to drive the loading clamping device 213 on the turntable 211 to rotate.

[0056] By the attached Figure 1 It can be seen that the turntable 211 of the embodiment of the present invention forms a frame-like structure through the turntable side arms 2111 radiating in different directions, and the turntable 211 has a preset operating distance relative to the bottom equipment, so that when the rotating loading platform 2 and the turning table 1 or the crystal rod transfer device are docked with each other to realize the crystal rod transfer, sufficient operating space is reserved for the crystal rod clamping device of the turning table 1 and the crystal rod transfer device. In the embodiment of the present invention, the bottom equipment of the turntable 211 is specifically a water receiving unit 23.

[0057] In a specific embodiment of the present invention, the angles between the turntable side arms 2111 are equal, that is, the turntable side arms 2111 are evenly arranged in the circumferential direction of the center of the rotating shaft, so that the loading and clamping devices 213 are evenly distributed on the turntable 211. In actual use, the angles between the turntable side arms 2111 can also be set to be unequal to meet other requirements of the on-site working conditions, such as making the rotating loading unit 21 dock with the flip table 1 and the crystal rod transfer device at the same time. Therefore, the unequal angles between the turntable side arms 2111 also fall within the protection scope of the present invention. In addition, each turntable side arm 2111 of the embodiment of the present invention is preferably configured to have two loading and clamping devices 213 to fully utilize the spatial position of the turntable 211 while making the position of each crystal rod not too compact, and the two loading and clamping devices 213 are distributed on different sides of the loading support column 212. Of course, in actual use, one or more loading and clamping devices 213 can also be set for each turntable side arm 2111 as needed.

[0058] Figure 1The specific structure of the rotating material loading unit 21 when there are two turntable side arms 2111 in the embodiment of the present invention is shown. As shown in the figure, when there are two turntable side arms 2111, the turntable 211 as a whole is in a straight line structure, and a total of four material loading clamping devices 213 are arranged on the turntable 211 of the straight line structure. It can be understood that the number of material loading clamping devices 213 in the embodiment of the present invention is not limited to four, and can be set according to needs. For example, when the number of turntable side arms 2111 is three, the turntable 211 forms a Y-shaped structure as a whole, and at this time the material loading clamping devices 213 can be set to six. The specific structure of the turntable 211 and the number of material loading clamping devices 213 in the embodiment of the present invention depend on the structural space and specific needs. In a specific embodiment of the present invention, the loading and clamping device 213 is arranged on two opposite sides of the loading support column 212, so that there are two crystal rod clamping stations corresponding to the loading and clamping devices 213 on the rotating loading unit 21 facing the same side. At this time, the crystal rods of the two crystal rod clamping stations can be docked by rotating the rotating loading unit 21 once.

[0059] Specifically, refer to Figure 1-Figure 4 The material loading and clamping device 213 of the embodiment of the present invention includes a pad 2131 and a pressure plate 2132, which are clamped at both ends of the crystal rod in the axial direction, so that the crystal rod is in a vertical state, so as to facilitate the side-to-side access to the crystal rod. The effective clamping surface of the pad 2131 and / or the pressure plate 2132 and the crystal rod is smaller than the end face of the crystal rod, so as to reserve a receiving space when the crystal rod is taken and placed from the axial end face of the crystal rod. The material loading and clamping device 213 provided by the present invention can not only meet the requirements of taking and placing the crystal rod from the side of the crystal rod, but also meet the requirements of taking and placing the crystal rod from the axial end face of the crystal rod, so as to adapt to the clamping requirements of different crystal rod clamping devices, that is, in the specific embodiment of the present invention, it can simultaneously meet the requirements of the rapid access and placement of the vertical crystal rod clamping device of the turning table 1, and also meet the requirements of the rapid access and placement of the horizontal crystal rod clamping device of the crystal rod transport device. Among them, the effective clamping surface is the contact surface between the plate 2131 and / or the pressure plate 2132 and the crystal rod when clamping the crystal rod. It can be understood that the flip table 1 and the crystal rod transfer device of the aforementioned embodiment are only a specific embodiment, which is used to illustrate that the material loading and clamping device 213 provided in the embodiment of the present invention can provide both lateral clamping space and transverse clamping space. The specific operation process and how to clamp the crystal rod are not the content that limits the protection scope of the present invention.

[0060] Further, the pad 2131 is an integrated planar structure or a multi-bracket structure. When clamping the crystal rod, the pad 2131 and the effective clamping surface of the crystal rod cover the center of the end face of the crystal rod to provide a stable support force for the crystal rod. Specifically, the effective clamping surface covers the center of the end face of the crystal rod, and the effective clamping surface coincides with the center of the crystal rod, or the plane formed by multiple effective clamping surfaces coincides with the center of the crystal rod. Specifically, the pad 2131 can be a planar structure extending outward along the turntable side arm 2111, and the specific extension angle is related to the number of turntable side arms 2111 on the turntable 211 and the relative positions of the flip table 1, the crystal rod transfer device and the rotating loading platform 2. The position setting of the pad 2131 is preferably that the direction of the pad 2131 extending outward corresponds to the direction of the flip table 1 after vertical flipping, the position of the pad 2131 corresponds to the position of the crystal rod clamping device on the crystal rod transfer device, and the pressure plate 2132 extends outward in the same direction as the pad 2131.

[0061] Furthermore, since the material loading and clamping device 213 of the embodiment of the present invention needs to realize the crystal rod transfer with other crystal rod clamping devices, the stability and reliability of different crystal rod clamping devices when transferring the crystal rod should be considered. The present invention can facilitate the horizontally clamped crystal rod clamping device to grasp the crystal rod through the side of the crystal rod by vertically clamping the crystal rod. The crystal rod clamping device for vertically clamping the crystal rod can also realize rapid clamping from the two axial ends of the crystal rod by rationally arranging the structural form of the pad 2131 and the pressure plate 2132.

[0062] Furthermore, the effective clamping surface of the pad 2131 and the crystal rod has a preset contact area on both sides or in the middle of the lower end surface of the crystal rod, so as to reserve a supporting space. For example, when the pad 2131 of the embodiment of the present invention is an integrated planar structure, the pad 2131 is used to support the center position of the bottom of the crystal rod, and sufficient contact space with the lower end surface of the crystal rod is reserved on both sides of the pad 2131, so that the lower clamping jaws of the vertical crystal rod clamping device can also stably support the crystal rod. Specifically, the lower clamping jaws of the vertical crystal rod clamping device can be two outwardly extending brackets. When docking with the material loading clamping device 213, the two outwardly extending brackets are located on both sides of the pad 2131. It can be understood that the pad 2131 and the lower clamping jaws of the vertical crystal rod clamping device can be interchanged to achieve the above functions.

[0063] Furthermore, in practical applications, when the crystal rod clamping device transports the crystal rod, it is also necessary to consider reserving movement space for the crystal rod clamping device. If the crystal rod is transported from top to bottom, it is also necessary to reserve longitudinal space for the lower clamping jaw of the crystal rod clamping device to move up and down. Therefore, a preset space is formed under the pad 2131 of the embodiment of the present invention to reserve longitudinal space for up and down movement when the crystal rod is taken and placed from the axial end face of the crystal rod. In a specific embodiment of the present invention, a preset distance is left between the turntable 211 and the water receiving tray 231, so as to reserve longitudinal space for the lower clamping jaw of the crystal rod clamping device to move up and down.

[0064] Furthermore, the pressure plate 2132 of the material-carrying clamping device 213 of the embodiment of the present invention and the upper clamping jaw of the vertical crystal rod clamping device also need to be arranged in coordination, that is, the pressure plate 2132 and the effective clamping surface of the crystal rod leave a preset contact area on both sides or in the middle of the upper end surface of the crystal rod compared to the crystal rod, so as to reserve a clamping space. For the crystal rod clamping device for vertically clamping the crystal rod, the lower clamping jaw supports the weight of the entire crystal rod and the clamping force applied by the upper clamping jaw. Therefore, for the pressure plate 2132 of the crystal rod clamping device of the embodiment of the present invention, it is only necessary to provide a stable clamping force for the crystal rod when clamping the crystal rod so that the crystal rod will not be thrown out or tipped over. Therefore, the pressing plate 2132 of the embodiment of the present invention includes a pressing plate bracket 21321 and a pressing plate protrusion 21322. The pressing plate bracket 21321 is an L-shaped structure composed of two side arms. One side arm of the pressing plate bracket 21321 is slidably connected to the material loading support column 212, and the end of the other side arm of the pressing plate bracket 21321 is connected to the pressing plate protrusion 21322. The lower end surface of the pressing plate protrusion 21322 contacts the upper end surface of the crystal rod to form an effective clamping surface with the crystal rod. A connecting beam 21323 is provided between the two side arms of 21321 to improve the stability of the pressure plate bracket 21321. The lower end surface of the pressure plate protrusion 21322 contacts the upper end surface of the crystal rod and covers the center of the upper end surface of the crystal rod. The area of ​​the lower end surface of the pressure plate protrusion 21322 in the embodiment of the present invention can be very small compared to the area of ​​the upper end surface of the crystal rod, so as to provide a stable clamping force for the crystal rod while reserving a clamping space and an up and down movement space for the upper clamping jaw of the crystal rod clamping device.

[0065] Furthermore, since the material loading and clamping device 213 is arranged on the turntable 211, the crystal rod clamped by the material loading and clamping device 213 will also rotate with the rotation of the turntable 211, and the clamped crystal rod will be subjected to the centrifugal force. Therefore, in order to resist the centrifugal force, the surface of the pad 2131 and / or the pressure plate 2132 is a soft material, specifically, the upper end surface of the pad 2131 and the lower end surface of the protrusion of the pressure plate 2132 are soft materials to increase the friction with the end surface of the crystal rod. In addition, the surface of the pad 2131 and / or the pressure plate 2132 is a soft material, which can also reduce the collision damage with the crystal rod. In the following embodiment, the lower surface of the pressure plate 2132 is the contact surface with the upper end surface of the crystal rod.

[0066] Furthermore, since the lower surface of the pressing plate 2132 is made of a soft material, the lower surface of the pressing plate 2132 is at a preset angle to the horizontal plane, so as to provide a horizontal component force for the crystal rod to resist the centrifugal force when the crystal rod is clamped. The size of the preset angle is related to the rotation speed range of the turntable 211 in actual application, and is intended to prevent the crystal rod from being thrown away by the centrifugal force. It can be understood that since the surface of the pressing plate 2132 is elastic, even if the bottom surface of the pressing plate 2132 and the upper end surface of the crystal rod have a preset angle, when the pressing plate 2132 is pressed downward, it will be in plane contact with the upper end surface of the crystal rod. Since the elastic material on the lower surface of the pressing plate 2132 provides the crystal rod with a component force that can resist the centrifugal force, the crystal rod is prevented from being thrown away by the centrifugal force.

[0067] Furthermore, the pad 2131 and the pressure plate 2132 of the embodiment of the present invention are arranged to extend laterally in the same direction along the loading support column 212 to reserve lateral clamping space for the crystal rod, so as to facilitate the lateral removal and placement of the crystal rod from the crystal rod. The present invention reserves sufficient lateral space for the crystal rod when clamping the crystal rod by arranging the pad 2131 and the pressure plate 2132 on the same side of the loading support column 212 in the lateral direction, so as to facilitate the rapid removal and placement of the crystal rod by the lateral clamping crystal rod clamping device. Among them, the pad 2131 and the loading support column 212 are relatively fixedly arranged, and the pressure plate 2132 can move up and down along the loading support column 212 to achieve the clamping and loosening of the crystal rod.

[0068] In a specific embodiment of the present invention, the pad 2131 is fixedly connected to the turntable 211, and the pressure plate 2132 can move vertically up and down to achieve the compression and loosening of the crystal rod. Specifically, the up and down movement of the pressure plate 2132 is achieved by the vertically arranged pressure plate guide rail 2133 and the pressure plate driving assembly, wherein the pressure plate 2132 is slidably connected to the pressure plate guide rail 2133, and the pressure plate driving assembly is used to drive the pressure plate 2132 to move up and down along the pressure plate guide rail 2133. Specifically, the pressure plate guide rail 2133 can be installed on the material loading support column 212, and the pressure plate 2132 is slidably connected to the pressure plate guide rail 2133 through a slider.

[0069] It can be understood that the pad 2131 of the embodiment of the present invention can also achieve the compression and loosening of the crystal rod by moving up and down. Therefore, the material loading and clamping device 213 of the embodiment of the present invention can also include a vertically arranged pad guide rail and a pad drive assembly not shown in the drawings, and the pad 2131 can be slidably connected to the pad guide rail to achieve the up and down movement of the pad 2131 on the pad guide rail, and the pad drive assembly is used to drive the pad 2131 to move up and down along the pad guide rail. Specifically, the pad 2131 is slidably connected to the pad guide rail through a slider, and the pad guide rail can be set together with the pressure plate guide rail 2133 on the material loading support column 212, or a pad support column can be set separately to support the pad 2131.

[0070] Furthermore, the pressing plate driving assembly is a pressing plate clamping cylinder 2134, the cylinder housing of the pressing plate clamping cylinder 2134 is fixedly connected to the material loading support column 212, and the movable end of the pressing plate clamping cylinder 2134 is connected to the pressing plate 2132. When the movable end of the pressing plate clamping cylinder 2134 is extended, the pressing plate 2132 is driven to move upward, and when the movable end of the pressing plate clamping cylinder 2134 is retracted, the pressing plate 2132 is driven to move downward. Of course, the pressing plate 2132 of the embodiment of the present invention can also be controlled to move up and down by other pressing plate driving assemblies. In addition, it should be noted that the embodiment of the present invention can also control the up and down movement of the pressing plate 2132 by other vertical moving assemblies, such as ball screws, etc. The relevant settings of the driving assembly of the pad 2131 can refer to the pad driving assembly.

[0071] Furthermore, the material carrier and clamping device 213 of the embodiment of the present invention is also provided with a crystal rod detection device (not shown in the drawings) for detecting whether a crystal rod is clamped on a corresponding station of the material carrier and clamping device 213. Specifically, the crystal rod detection device may be a diffuse reflection sensor, which detects whether there is material on the material carrier and clamping device 213 by the diffuse reflection sensor, thereby avoiding conflicts when loading and unloading materials.

[0072] The following is a specific embodiment of the present invention to illustrate the operation flow of the material carrier and clamping device 213 for crystal ingot transportation and the crystal ingot clamping device. The material carrier and clamping device 213 needs to cooperate with the turning table 1 to realize the loading and unloading of the crystal ingot. The specific structure of the turning table 1 can be as follows: Figure 5 , Figure 6 and Figure 7 As shown, the turning table 1 includes a loading and unloading table 11, which is rotatably connected to the turning table base 13. The crystal rod is converted from a lying position to a vertical position by controlling the flip conversion of the loading and unloading table 11 between horizontal and vertical positions.

[0073] Furthermore, the loading and unloading platform 11 specifically includes a platform base 111 and a positioning base plate 112 that can move axially along the platform base 111, and the positioning base plate 112 is vertically connected to the platform base 111 at 90 degrees. A clamping block 113 is also provided at the top of the platform base 111, and the clamping block 113 can rotate on the platform base 111 and can move along the axial direction of the platform base 111. The clamping block 113 can contact the top end face of the crystal rod and cooperate with the positioning base plate 112 to achieve the clamping and loosening of the crystal rod. That is, the positioning base plate 112 can be the lower clamping jaw of the crystal rod clamping device mentioned in the aforementioned embodiment, and the clamping block 113 is the upper clamping jaw of the crystal rod clamping device mentioned in the aforementioned embodiment.

[0074] Furthermore, when loading the rotating loading platform 2, the loading and unloading platform 11 is first flipped to a vertical position and then moved to the crystal rod clamping station of the corresponding loading and clamping device 213 on the rotating loading platform 2. When the crystal rod clamped by the loading and unloading platform 11 is transported to the top of the pad 2131 of the loading and clamping device 213, the positioning bottom plate 112 and the clamping block 113 of the loading and unloading platform 11 are first controlled to move downward at the same time so that the positioning bottom plate 112 and the pad 2131 of the loading and clamping device 213 are in the same plane; then the pressure plate 2132 of the loading and clamping device 213 is controlled to move downward until it contacts the upper end surface of the crystal rod to clamp the crystal rod; then the positioning bottom plate 112 of the loading and unloading platform 11 is controlled to release the clamping block 113 while continuing to move downward; finally, the loading and unloading platform 11 is controlled to exit. The above steps complete the transfer of the crystal rod between the flipping platform 1 and the rotating loading platform 2. At this time, since the positioning base plate 112 needs to continue to move downward for a distance, a certain distance is left between the pad 2131 and the water receiving unit 23 below the pad 2131, that is, the pad 2131 is in a suspended state, and a longitudinal space is reserved for the positioning base plate 112 of the loading and unloading platform 11 to move downward. It can be understood that the operation process of taking the crystal rod from the loading and clamping device 213 of the turning platform 1 can also be reversed, and no further description is given in comparison with the embodiment of the present invention.

[0075] Based on the above embodiments, it can be known that the pad 2131 of the loading and clamping device 213 provided by the present invention and the material table bottom plate 112 of the loading and unloading table 11 need to simultaneously support the crystal rod when the crystal rod is transported. Therefore, the effective lower clamping area of ​​the pad 2131 and the lower end surface of the crystal rod is a rectangular area formed by axially translating a certain distance on both sides of the center axis of the crystal rod. The contact area between the material table bottom plate 112 of the loading and unloading table 11 and the lower end surface of the crystal rod is reserved on both sides of the effective lower clamping area. When the crystal rod is transported, the material table bottom plate 112 supports the crystal rod from both sides of the pad 2131. Therefore, both the material table bottom plate 112 and the pad 2131 can independently and stably support the crystal rod.

[0076] Furthermore, since the lateral space of the crystal ingot is relatively large when the material carrier clamping device 213 provided in the embodiment of the present invention clamps the crystal ingot, when docking with the crystal ingot clamping device that clamps the crystal ingot horizontally, after the horizontal crystal ingot clamping device places the crystal ingot on the pad 2131, the pressure plate 2132 is controlled to move downward until it contacts the upper end surface of the crystal ingot to clamp the crystal ingot, and the left and right clamping claws of the horizontal crystal ingot clamping device are released and withdrawn to complete the delivery of the crystal ingot. Conversely, the operation process of taking away the crystal ingot from the material carrier clamping device 213 is also easy to implement.

[0077] The electrical and pneumatic devices on the rotating material carrier unit 21 of the embodiment of the present invention are powered by the rotating material carrier electrical unit 22 (hereinafter referred to as the electrical unit), for example, a pneumatic path is provided for the clamping cylinder 2134 of the material carrier clamping device 213, and a power path is provided for the crystal rod detection device of the material carrier clamping device 213. Figure 1 , Figure 8 and Fig. 9 The electrical unit 22 provided in the embodiment of the present invention is introduced in detail.

[0078] The electrical unit 22 of the present invention is used to provide energy and power for the rotating material loading unit 21 on the rotating material loading platform 2, and the rotating material loading unit 21 can rotate on the rotating material loading platform 2. Specifically, the electrical unit 22 provided in the embodiment of the present invention includes an electrical fixing part 221 and an electrical rotating part 222, the electrical fixing part 221 is connected to an external energy input device, the electrical rotating part 222 is fixedly arranged on the rotating material loading unit 21, and can rotate with the rotating material loading unit 21, the electrical fixing part 221 is connected to the electrical rotating part 222 through a slip ring assembly 223, and the electrical rotating part 222 is connected to the electrical equipment in the rotating material loading unit 21 through an electrical line to provide energy and power for the electrical equipment in the rotating material loading unit 21.

[0079] The external energy specifically includes the air source of the pneumatic device and the power source of the electric device. The pneumatic device can be a cylinder, and the electric device can be a motor, a sensor, a processor and other electrical components. Since there is no relative motion between the electrical rotating part 222 and the rotating material loading unit 21, the line winding problem caused by the rotation of the rotating material loading unit 21 is avoided.

[0080] Furthermore, the electrical fixing part 221 of the embodiment of the present invention includes a slip ring bracket 2211, one end of the slip ring bracket 2211 is connected to the external fixing device, and the other end is fixedly connected to the slip ring assembly fixing part 2231, which is used to fix the position of the slip ring assembly 223 in the rotating material loading unit 21. That is, the external energy input device and the electrical circuit and the electrical structure of the rotating material loading unit 21 are always in a fixed position to improve the stability of the equipment operation.

[0081] Furthermore, the electrical fixing part 221 further includes a slip ring connection plate 2212, and the slip ring assembly 223 is connected to the slip ring bracket 2211 via the slip ring connection plate 2212. The slip ring bracket 2211 is connected to the slip ring assembly fixing part 2231 via the slip ring connection plate 2212, and the slip ring connection plate 2212 is a disc-shaped support structure for providing support for the electrical circuit of the external energy input device. Figure 8 As shown, the slip ring connecting disk 2212 is a rotating disk structure with an outer diameter larger than the outer diameter of the slip ring assembly 223, and a fastening device is provided on the slip ring connecting disk 2212. The slip ring connecting disk 2212 is provided with a hollow structure to facilitate the external electrical circuit to be fixed on the slip ring connecting disk 2212 and connected to the electrical input port of the slip ring assembly 223 through the hollow device.

[0082] The electrical fixing part 221 of the present invention is fixedly connected to the frame structure of the crystal ingot processing system, that is, one end of the slip ring bracket 2211 of the electrical fixing part 221 is connected to the slip ring assembly fixing part 2231 through the slip ring connecting plate 2212, and the other end of the slip ring bracket 2211 is fixedly connected to the frame structure of the crystal ingot processing system (not shown in the drawings). The frame structure of the crystal ingot processing system can be an external structure supporting the entire crystal ingot processing system, or it can be an external frame of the crystal ingot processing unit. The other end of the slip ring bracket 2211 is fixedly connected to the frame structure of the crystal ingot processing system (not shown in the drawings), which is conducive to stabilizing the entire crystal ingot processing system, and can introduce the gas source and power supply on the crystal ingot processing unit to the rotating loading table.

[0083] Further, the slip ring assembly 223 of the embodiment of the present invention is as follows Fig. 9 As shown, the slip ring fixed part 2231 is provided with a slip ring air inlet 2233, and the slip ring rotating part 2232 is provided with a slip ring air outlet 2234. The slip ring air inlet 2233 and the slip ring air outlet 2234 are correspondingly arranged to realize uninterrupted air supply to the gas-consuming equipment of the rotating material loading unit 21, and the slip ring rotating part 2232 can rotate relative to the slip ring fixed part 2231. In addition, the slip ring assembly 223 of the embodiment of the present invention also includes an electric input interface provided on the slip ring fixed part 2231 and an electric output interface provided on the slip ring rotating part 2232, which are not shown in the drawings. The electric input interface and the electric output interface are correspondingly arranged to realize uninterrupted power supply to the electric equipment of the rotating material loading unit 21.

[0084] Furthermore, the electrical rotating part 222 of the electrical unit 22 of the embodiment of the present invention includes a wiring pipe fixedly connected to the rotating material loading unit 21, the wiring pipe is fixedly connected to the slip ring rotating part 2232, and the electrical lines connected from the slip ring rotating part 2232 are connected to various electrical devices on the rotating material loading unit 21 through the wiring pipe. Since the wiring pipe and the rotating material loading unit 21 are in a relatively static state, the gas pipeline and the electrical line on the wiring pipe will not cause the line entanglement problem as the rotating material loading unit 21 rotates.

[0085] Further, the wiring pipe of the embodiment of the present invention includes a vertical pipeline 2221 and a horizontal pipeline 2222, wherein one end of the vertical pipeline 2221 is connected to the slip ring rotating part 2232 of the slip ring assembly 223, and the other end is fixedly connected to the rotating material loading unit 21. Specifically, the vertical pipeline 2221 is connected to the rotating disk 211 of the rotating material loading unit 21, and the vertical pipeline 2221 can rotate with the rotating disk 211, and provide vertical support for the slip ring assembly 223 and the horizontal pipeline 2222.

[0086] Furthermore, one end of the horizontal pipeline 2222 is fixedly connected to the vertical pipeline 2221 , and the other end of the horizontal pipeline 2222 is fixedly connected to the rotating loading unit 21 , and the electrical circuit is connected to the electrical equipment on the rotating loading unit 21 through the horizontal pipeline 2222 .

[0087] Specifically, it can be known from the above embodiments that the rotating loading unit 21 includes a turntable 211 and a loading support column 212 arranged on the turntable 211, a vertical pipeline 2221 is fixedly connected to the turntable 211, a horizontal pipeline 2222 is fixedly connected to the loading support column 212, and an electrical circuit is connected to the electrical equipment on the loading support column 212 through the horizontal pipeline 2222. In addition, the horizontal pipeline 2222 can also play a supporting role for the loading support column 212 to enhance the stability of the entire system. It can be understood that the number of horizontal pipelines 2222 in the embodiment of the present invention is set relative to the number of loading support columns 212, so as to provide support for each loading support column 212 and the path of the gas pipeline and / or electrical circuit, that is, at least two loading support columns 212 are arranged on the turntable 211, the vertical pipeline 2221 is arranged between the loading support columns 212, and the horizontal pipeline 2222 is respectively connected to each loading support column 212. In a specific embodiment of the present invention, when the number of loading support columns 212 is two, the wiring pipe forms a cross structure as shown in the figure. It should be noted that the two horizontal pipes 2222 of the wiring pipe can be an integrated pipe as shown in the figure, or they can be two horizontal pipes 2222 fixedly connected to the vertical pipe 2221 respectively.

[0088] In a specific embodiment of the present invention, it can be known from the above embodiment that the rotating material loading unit 21 is provided with a material loading clamping device 213, and the material loading clamping device 213 is provided with a clamping cylinder and a crystal rod detection device, the clamping cylinder is used to control the material loading clamping device 213 to clamp the crystal rod, the crystal rod detection device is used to detect whether the material loading clamping device 213 clamps the crystal rod, and the electrical circuit on the electrical rotating part 222 is connected to the clamping cylinder and the crystal rod detection device. Specifically, the clamping cylinder can be the pressure plate clamping cylinder 2134 described in the above embodiment.

[0089] The electrical unit 22 of the embodiment of the present invention is connected to the external energy input device through the electrical fixing part 221, is fixedly connected to the rotating loading unit 21 on the rotating loading platform 2 through the electrical rotating part 222, and is connected to the electrical equipment in the rotating loading unit 21 through the electrical line. While continuously providing energy and power to the electrical equipment of the rotating loading unit 21, it also avoids the problem of line entanglement in the rotating loading unit 21.

[0090] In a specific embodiment of the present invention, since there are water stains on the crystal rod clamped by the rotating material loading unit 21, the rotation of the rotating material loading unit 21 further accelerates the throwing out of the water stains on the crystal rod. Therefore, the present invention sets a rotating material loading platform water receiving unit 23 (hereinafter referred to as the water receiving unit) to receive the water stains dripping from the crystal rod. Figure 1 , Fig.10 The water receiving unit 23 of the embodiment of the present invention is introduced in detail.

[0091] The water receiving unit 23 provided in the embodiment of the present invention includes a water receiving tray 231, which is arranged below the rotating loading unit 21 of the rotating loading platform 2. A rotating drive unit 24 is arranged below the water receiving tray 231. The water receiving tray 231 is used to receive water stains flowing down from the rotating loading unit 21 to prevent the water stains from splashing onto the rotating drive unit 24.

[0092] Furthermore, the water collecting tray 231 of the embodiment of the present invention includes a connecting shaft through hole 2311, through which the connecting component between the rotating loading unit 21 and the rotating driving unit 24 passes, specifically, through which the connecting tray 244 between the rotating loading unit 21 and the rotating driving unit 24 passes. The connecting shaft through hole 2311 is surrounded by connecting shaft through hole water retaining edges 2312 to prevent water from flowing out through the connecting shaft through hole 2311.

[0093] Furthermore, a drain port 2315 is provided on the water receiving tray 231, and a water receiving pipe is connected below the drain port 2315. The drain port 2315 is used to discharge the water in the water receiving tray 231 through the drain port. At the same time, water receiving tray retaining edges 2316 are also provided on the four edges of the water receiving tray 231 to prevent the water in the water receiving tray 231 from flowing out through the four edges of the water receiving tray 231. It can be understood that the drain port 2315 can be a plurality of drain ports 2315 distributed in different directions, and the interior of the water receiving tray 231 has a certain slope along the direction of the drain port 2315, so that the water can quickly flow out through the drain port 2315.

[0094] Furthermore, the water receiving tray 231 is provided with a clamping cylinder through hole 2313 for the clamping cylinder on the rotating material loading unit 21 to pass through. Due to the influence of the up and down movement stroke of the pressing plate 2132 of the material loading clamping device 213, the bottom end surface of the pressing plate clamping cylinder 2134 may pass through the water receiving tray 231. At this time, the water receiving tray 231 is also provided with a pressing plate clamping cylinder through hole for the pressing plate clamping cylinder 2134 to pass through. It can be understood that the clamping cylinder through hole water retaining edge 2314 is provided on the four edges of the clamping cylinder through hole 2313 to prevent water from flowing out through the clamping cylinder through hole 2313. The clamping cylinder through hole 2313 of the embodiment of the present invention can be a pressing plate clamping cylinder 2134 or a pad clamping cylinder or other device that may pass through the water receiving tray 231.

[0095] Furthermore, the water receiving tray 231 is fixedly connected to the rotating material loading unit 21, and rotates together with the rotating material loading unit 21 under the drive of the rotating driving unit 24. Since the pressure plate clamping cylinder 2134 on the rotating material loading unit 21 rotates together with the rotating material loading unit 21, the embodiment of the present invention rotates the water receiving tray 231 together with the rotating material loading unit 21, so that the pressure plate clamping cylinder 2134 and the water receiving tray 231 are relatively stationary, so that there is no interference between the water receiving tray 231 and the pressure plate clamping cylinder 2134.

[0096] In a specific embodiment of the present invention, it can be known from the above embodiments that the rotating loading platform 2 further comprises a turntable frame 25 fixedly connected to the base of the rotating loading platform 2, a rotating drive unit 24 is fixedly mounted on the turntable frame 25, a connecting disk 244 is rotatably connected to the turntable frame 25, a rotating shaft of the rotating drive unit 24 is fixedly connected to the connecting disk 244, the connecting disk is located above the turntable frame 25, the rotating loading unit 21 and the water receiving tray 231 are respectively fixedly connected to the connecting disk 244, and the rotating drive unit 24 can drive the connecting disk 244 to rotate, so as to drive the rotating loading unit 21 and the water receiving tray 231 to rotate together. Among them, the connecting disk 244, the rotating drive unit 24 and the water receiving tray 231 are concentrically connected to ensure the running stability when the rotating drive unit 24 and the water receiving tray 231 rotate together.

[0097] Furthermore, the outer contour of the water receiving tray 231 in the horizontal direction is larger than the outer contour of the rotating loading unit 21 projected onto the horizontal plane, so that all the water stains flowing down from the rotating loading unit 21 can be received by the water receiving tray.

[0098] It can be understood that when the equipment on the rotating loading unit 21 does not need to pass through the water receiving tray 231, the water receiving tray 231 of the embodiment of the present invention can also be fixedly connected to the rotating drive unit 24, that is, the water receiving tray 231 is fixedly connected to the turntable frame 25, and the horizontal outer contour of the water receiving tray is larger than the outer contour projected onto the horizontal plane when the rotating loading unit 21 rotates, so that all water stains flowing down from the rotating loading unit 21 can be received by the water receiving tray 231.

[0099] In a specific embodiment of the present invention, a turntable 211 is provided on the rotating loading unit 21, and the rotating driving unit 24 is used to drive the turntable 211 to rotate. The turntable 211 covers the connecting shaft through hole 2311 and the clamping cylinder through hole 2313 in the vertical direction to prevent water stains from directly dripping onto the rotating driving unit 24 through the connecting shaft through hole 2311 or the pressure plate clamping cylinder through hole 2313.

[0100] Another aspect of the embodiment of the present invention further provides a control method for a rotating loading platform 2. The rotating loading platform 2 provided in the embodiment of the present invention is a loading component of a crystal rod processing system, and is specifically used to cooperate with the turning table 1 and the crystal rod transfer device to realize loading and unloading operations of the crystal rod. The specific process of the rotating loading platform 2 in the working process of the embodiment of the present invention is described in detail below:

[0101] The rotating loading platform 2 of the embodiment of the present invention cooperates to realize the loading and unloading of the crystal ingot of the crystal ingot processing system, specifically including the following steps: Fig.11 The following steps are shown:

[0102] S1, controlling the rotation of the rotating loading unit 21 of the rotating loading platform 2, so that the crystal rod clamping station holding the crystal rod to be processed on the rotating loading unit 21 rotates to the first crystal rod loading and unloading station in sequence; wherein the rotating loading unit 21 is provided with a plurality of crystal rod clamping stations, and each crystal rod clamping station is provided with a loading clamping device 213;

[0103] S2, control the loading and clamping device 213 on the first crystal rod loading and unloading station to provide the clamped crystal rod to be processed, and receive the processed crystal rod transferred back. The rotating material waiting table provided in the embodiment of the present invention can provide materials for multiple crystal rods to be processed at the same time. When the crystal rod processing system has multiple processing stations, the crystal rod transfer device can quickly replenish the crystal rods to be processed for each processing station, and can receive multiple processed crystal rods at the same time. It avoids the time waste caused by the flip table 1 directly providing the crystal rod transfer device with the crystal rod to be processed, and shortens the loading and unloading time beat.

[0104] Furthermore, the control method of the rotating loading platform 2 of the embodiment of the present invention also includes a process of unloading the processed crystal rod, which specifically includes the following steps:

[0105] S3, controlling the rotating loading unit 21 of the rotating loading platform 2 to rotate, so that the crystal ingot clamping station holding the processed crystal ingot on the rotating loading unit 21 rotates to the second crystal ingot loading and unloading station in sequence;

[0106] S4, controlling the loading and clamping device 213 on the second crystal ingot loading and unloading station to deliver the clamped processed crystal ingot to realize the unloading and transportation of the processed crystal ingot.

[0107] Furthermore, the control method of the rotating material carrier 2 in the embodiment of the present invention also includes a method for loading and reserving the crystal rods to be processed for the rotating material carrier 2, and the method also includes:

[0108] S01, controlling the rotation of the rotating loading unit 21 of the rotating loading platform 2, so that the crystal ingot clamping station on the rotating loading unit 21 that does not clamp the crystal ingot rotates to the second crystal ingot loading and unloading station in sequence;

[0109] S02, controlling the loading and clamping device 213 on the second crystal ingot loading and unloading station to accept the crystal ingot to be processed, so as to realize the loading and storage of the crystal ingot to be processed on the rotating loading unit 21.

[0110] It should be noted that the first loading and unloading station in a specific embodiment of the present invention is specifically the docking station of the rotating loading platform 2 and the crystal rod transporting device, so as to enable the crystal rod transporting device to load and unload the crystal rods of the crystal rod processing station of the crystal rod processing system. The second loading and unloading station is specifically the docking station of the rotating loading platform 2 and the turning table 1, so as to enable the turning table 1 to provide the crystal rod to be processed to the rotating loading platform 2 or to clamp the processed crystal rod from the rotating loading platform 2 and transport it away. In addition, the first loading and unloading station and the second loading and unloading station are not limited to one, and can be two or more.

[0111] Furthermore, the control method of the rotating loading platform 2 of the embodiment of the present invention takes unloading and loading to the crystal rod processing station as the best priority to ensure that the waiting time for unloading and loading of the crystal rod processing system is the shortest. When all processing stations of the crystal rod processing system are working, it is used to perform the process of unloading and loading and storage, wherein unloading and storage can be performed simultaneously or separately, and there is no limitation on how to perform the present invention specifically. It should be noted that this embodiment illustrates an optimal implementation of the present invention and is not intended to limit the scope of protection of the present invention.

[0112] The specific operation process of the rotary loading platform 2 of the present invention is described below in conjunction with a specific embodiment of the present invention. In the specific embodiment of the present invention, the rotary loading platform 2 has 4 crystal rod clamping stations, the crystal rod processing system has 4 crystal rod processing stations, and there are two first crystal rod loading and unloading stations and two second crystal rod loading and unloading stations.

[0113] Loading and unloading of the crystal rod processing system: first, the four crystal rods to be processed are respectively placed on the four crystal rod clamping stations of the rotary loading platform 2 through the turning table 1; the rotary loading platform 2 rotates to rotate the two crystal rod clamping stations on the rotary loading platform 2 to the first loading and unloading station, that is, the clamping station of the crystal rod transfer device; the crystal rod transfer device clamps the crystal rod to be processed clamped by the first loading and unloading station and sends it to the crystal rod processing station of the crystal rod processing system; the crystal rod loading device first clamps the processed crystal rod at the crystal rod processing station, and then rotates to load the crystal rod to be processed to the processing station; after the crystal rod transfer device completes the above operations twice, the rotary loading platform 2 rotates 180 degrees, and rotates the other two crystal rod clamping stations to the first loading and unloading station, and the crystal rod transfer device loads the remaining two crystal rods to be processed to the crystal rod processing system twice, so as to realize loading and unloading of all processing stations of the entire crystal rod processing system.

[0114] In the above embodiment, the crystal rod transfer device has two crystal rod clamping devices, one side of the crystal rod clamping device is used to clamp the crystal rod to be processed, and the other side of the crystal rod clamping device is used to clamp the processed crystal rod. For a crystal rod transfer device with only one crystal rod clamping device, a processed crystal rod can be first transferred to the rotating loading platform 2, and then the processing stations of the crystal rod processing system can be loaded in sequence. That is, if there is a crystal rod clamping station on the rotating loading platform 2 that does not clamp a crystal rod, the processed crystal rod can be first clamped to the crystal rod clamping station that clamps the crystal rod, and then the loading and unloading process is repeated in sequence to realize the overall loading and unloading of the crystal rod processing system.

[0115] The rotary loading platform provided by the present invention has the following advantages:
