Description

Technical Field

[0001] This invention belongs to the field of silicon material processing technology, and specifically relates to a loading and unloading mechanism for a squaring machine and a corresponding squaring machine. Background Technology

[0002] Currently, the main method for squaring silicon rods on the market is to use a wire saw with a single diamond wire for reciprocating cutting. The production line of the squaring machine is the main factor restricting production capacity and quality, and the low efficiency of silicon rod feeding and unloading is the key factor.

[0003] The existing squaring machine's loading and unloading mechanisms have the following problems: 1. They typically use material carts in conjunction with tooling, resulting in a redundant and complex structure, high time and labor costs, high manufacturing costs, and low production efficiency, failing to meet current production demands. 2. The structure is fixed, requiring different specifications of workpieces to be cut on corresponding squaring machines. 3. The squaring machine's loading and unloading are handled by two separate lines, leading to a less compact overall structure and requiring a large workshop layout. Therefore, a new loading and unloading mechanism that can solve these problems is needed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention proposes a loading and unloading mechanism for a squaring machine and a corresponding squaring machine. The entire loading and unloading process is automated, allowing seamless connection of the workpiece to be processed onto the worktable and return of the processed workpiece from the worktable to the loading and unloading mechanism, thereby improving the operating efficiency of the equipment. Furthermore, the size of the workpiece transported by the loading and unloading mechanism is adjustable, making it adaptable to various specifications of cylindrical silicon rods available on the market.

[0005] To achieve the above objectives, the present invention provides a loading and unloading mechanism for a square-opening machine. The loading and unloading mechanism is used to transport the workpiece to be processed to the worktable, and the worktable is used to transport the workpiece to be processed to the next process and to transport the processed workpiece back to the loading and unloading mechanism. The loading and unloading mechanism includes a flipping execution component, a workpiece driving platform, and a base.

[0006] The workpiece driving platform is located above the flipping execution component and is hinged to the flipping execution component; the base is located below the flipping execution component and is slidably connected to the flipping execution component; the flipping execution component is provided with a telescopic structure, the housing of the telescopic structure is fixed to the flipping execution component, and the push rod of the telescopic structure is hinged to the bottom of the workpiece driving platform.

[0007] The workpiece driving platform is adjacent to the worktable, and the flipping execution component is used to drive the workpiece driving platform to slide and flip, so that the workpiece driving platform slides and flips towards or away from the worktable.

[0008] The worktable has a preset position for the workpiece to fall into, and when the workpiece driving platform flips to the worktable position, the workpiece is located above the worktable.

[0009] Furthermore, the workpiece driving platform drives the workpiece to move towards or away from the worktable. The direction in which the workpiece moves towards the worktable is the loading direction of the workpiece, and the direction in which the workpiece moves away from the worktable is the unloading direction of the workpiece.

[0010] Furthermore, the workpiece driving platform includes a fixed fork arm; the fixed fork arm is fixed to the end of the workpiece driving platform along the workpiece feeding direction;

[0011] The worktable has a lifting boss, and the fixed fork arm has an opening that faces the lifting boss of the worktable, and the opening of the fixed fork arm matches the lifting boss of the worktable.

[0012] Furthermore, the flipping actuator includes a slide rail, a mounting plate, a pin cylinder, a forward / reverse motor, and a rack;

[0013] The slide rail has two sections, and the top surface of the base has a rectangular slot. The two slide rails are symmetrically fixed on both sides of the rectangular slot of the base and are parallel to each other. A slider is slidably connected to each slide rail. The mounting plate is horizontally fixed to the top surface of the slider. The rack is fixed to the top surface of the base along the length of the slide rail and is located below the mounting plate. The teeth of the rack face the rectangular slot of the top surface of the base.

[0014] The mounting plate is provided with a cylinder mounting slot, which is located directly above the rectangular slot on the top surface of the base; the pin cylinder passes obliquely through the cylinder mounting slot, and the mounting plate and the pin cylinder are rotatably connected to the workpiece drive platform.

[0015] The forward and reverse motors are directly connected to the gears via a planetary reducer. The planetary reducer is fixed to the top surface of the mounting plate. The output shaft of the planetary reducer passes through the mounting plate and is connected to the gear on the bottom surface of the mounting plate. The gear meshes horizontally with the rack.

[0016] Furthermore, the workpiece driving platform also includes a driving assembly, which includes a workpiece conveying track, comprising rollers, unpowered rollers, a sprocket and chain drive assembly, roller seats, guide plates, and a base plate;

[0017] The base plate is rotatably connected to the mounting plate and the pin cylinder, and the fixed fork arm is installed perpendicularly to the edge of the base plate; multiple roller seats are symmetrically installed in multiple rows along the workpiece movement direction on the top surface of the base plate, with two roller seats in each row, and a roller installed at the same position in each roller seat. The two roller seats are rotatably connected to the roller through the roller; there are two guide plates, each guide plate is obliquely installed on the top of each row of roller seats, and multiple unpowered rollers are fixed perpendicular to the guide plate along their axis and located inside the roller seats. The number of unpowered rollers is the same as the number of roller seats.

[0018] The sprocket and chain drive assembly includes a sprocket, a chain, and a conveyor motor. The outer side of the rollers of each roller seat in a single row is connected to the sprocket via a connecting shaft. The chain is wound around the outer side of each sprocket. A guide gear is coaxially mounted on the outer side of one of the sprockets. The conveyor motor is fixedly mounted on the base. The output shaft of the conveyor motor is connected to a drive gear. The drive gear of the conveyor motor is located directly below the guide gear. The drive gear and the guide gear are wound with a drive chain on their outer sides.

[0019] Furthermore, the conveying motor of the sprocket and chain drive can control the sprocket and chain to rotate clockwise or counterclockwise. When rotating clockwise, the sprocket rolls towards the worktable to feed materials, and when rotating counterclockwise, the sprocket rolls away from the worktable to unload materials.

[0020] Furthermore, it also includes a track-fixing and conveying platform;

[0021] The fixed-track conveying platform has the same structure as the drive assembly of the workpiece drive platform. The fixed-track conveying platform is fixed to the top of the base, and the workpiece conveying track of the fixed-track conveying platform is connected to the workpiece conveying track of the workpiece drive platform.

[0022] The difference between the fixed-track conveying platform and the workpiece driving platform is that the fixed-track conveying platform also includes a discharge baffle, and the flipping execution component also includes a buffer;

[0023] The discharge baffle is fixed to the top surface of the base along the workpiece discharge direction;

[0024] The buffer is fixed to the top surface of the mounting plate, with the head of the buffer facing the workpiece feeding direction. The drive assembly is flipped to a vertical position, and the buffer contacts and buffers with the bottom plate of the drive assembly.

[0025] Further, the workpiece is loaded onto the conveyor track of the fixed-rail conveyor platform and conveyed onto the conveyor track of the workpiece drive platform. The flipping execution component controls the workpiece drive platform, along with the workpiece, to flip towards the worktable to a vertical position. The lifting boss of the worktable rises and passes through the opening of the fixed fork arm to lift the workpiece, so that the workpiece to be processed falls onto the lifting boss of the worktable. The flipping execution component controls the workpiece drive platform to maintain a vertical position and move towards the fixed-rail conveyor platform at a preset distance. After the workpiece is processed, the flipping execution component controls the workpiece drive platform to move towards the worktable in a vertical position until the fixed fork arm matches the lifting boss of the worktable. When the lifting boss of the worktable descends along the opening of the fixed fork arm, the processed workpiece falls onto the fixed fork arm. The flipping execution component controls the workpiece drive platform to flip towards the fixed-rail conveyor platform to a horizontal position. The workpiece conveyor tracks on the fixed-rail conveyor platform and the workpiece drive platform are connected to each other. The processed workpiece is conveyed horizontally from the workpiece drive platform to the fixed-rail conveyor platform to complete the unloading.

[0026] Furthermore, the fixed fork arm is a U-shaped flat plate, and the bottom of the base has multiple casters.

[0027] A squaring machine includes a worktable, a cutting mechanism, a loading and unloading mechanism, and a frame; the worktable, the cutting mechanism, and the loading and unloading mechanism are all mounted on the frame.

[0028] The worktable has a track, the loading and unloading mechanism is adjacent to the worktable and located at one end of the track, and the cutting mechanism is located at the other end of the track; the worktable is transported along the track to the cutting mechanism based on the workpiece loaded by the loading and unloading mechanism, and the workpiece cut by the cutting mechanism is transported to the loading and unloading mechanism for unloading.

[0029] The loading and unloading mechanism is any of the loading and unloading mechanisms for the square-opening machine described above.

[0030] The beneficial effects of this invention are:

[0031] First, in this invention, the loading and unloading strokes are located on the same conveying track, and the movement directions of the conveying tracks are opposite. The conveying track of the fixed-track conveying platform and the workpiece placement platform is rotated by the conveying motor. The workpiece is placed on the fixed-track conveying platform for loading by automated equipment or manual operation. The slide rail structure of the flipping execution component controls the horizontal displacement of the workpiece placement platform, and the telescopic structure of the flipping execution component controls the workpiece placement platform to flip along a preset direction and angle. The workpiece placement platform is adjacent to the worktable. The workpiece placement platform flips towards the worktable, and the workpiece is dropped vertically onto the worktable to complete the loading process. The processed workpiece is received by the workpiece placement platform and flipped to a horizontal position. Its conveying track is connected to the conveying track of the fixed-track conveying platform. The processed workpiece is transported from the workpiece placement platform to the fixed-track conveying platform in a horizontal position to complete the unloading. The entire loading and unloading process is automated, which can seamlessly connect the workpiece to be processed to the worktable, improve the operating efficiency of the equipment, and the size of the workpiece transported by the loading and unloading mechanism is adjustable, which can adapt to various specifications of cylindrical silicon rods on the market.

[0032] Second, the discharge baffle of the present invention is fixedly installed on the top surface of the base and adjacent to the outermost roller, which can prevent the workpiece being discharged from sliding down the conveying track of the fixed rail conveying platform; the opening of the fixed fork arm matches the boss structure of the worktable, the boss structure of the worktable is located in the opening of the fixed fork arm, and the workpiece on the fixed fork arm can be lifted and removed from the fixed fork arm by the lifting of the boss structure of the worktable.

[0033] Third, the buffer of the present invention is fixed on the top surface of the mounting plate, and the head of the buffer faces the workpiece feeding and conveying direction. When the workpiece placement platform is flipped to a vertical position, the bottom plate of the workpiece placement platform contacts the buffer to buffer, which can prevent the workpiece on the workpiece placement platform from shaking and falling.

[0034] Fourth, the fixed fork arm of the present invention is equipped with a limit switch. The limit switch is connected to the conveyor motor of the sprocket and chain drive assembly of the workpiece placement platform through a signal line. When the roller of the workpiece placement platform drives the workpiece to move to the front end of the conveyor track, the workpiece contacts the limit switch. The limit switch feeds back the electric shock action signal to the conveyor motor through the signal line. The conveyor motor stops working upon receiving the signal, which can prevent the workpiece from jumping and falling due to continued movement on the work track.

[0035] Fifth, the base of the present invention has multiple casters at the bottom, which facilitates the movement and adjustment of the distance between the workpiece placement platform and the worktable of the next process, ensuring that the workpiece placement platform is flipped to the designated position where the workpiece falls into the worktable.

Detailed Implementation

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] like Figure 1As shown, this invention provides a loading and unloading mechanism for a squaring machine and a corresponding squaring machine. This mechanism is used to transport workpieces to be processed to the workbench of the next process, realizing the loading process of the workpieces to be processed, and to receive the processed workpieces transported from the workbench, realizing the unloading process of the processed workpieces. The loading and unloading mechanism includes a fixed-track conveyor platform 1, a tilting conveyor platform 2, a tilting execution component 3, and a base 4. The fixed-track conveyor platform 1 and the tilting conveyor platform 2 have workpiece conveying tracks that interlock. The base 4 is a frame structure, with the fixed-track conveyor platform 1 fixed to one side of the top of the base 4, and the tilting execution component 3 fixed to the other side of the top of the base 4. The tilting execution component 3 has a slide rail structure and a telescopic structure. The tilting conveyor platform 2 is connected to the slide rail structure and the telescopic structure of the tilting execution component 3. The slide rail structure of the tilting execution component 3 controls the horizontal displacement of the tilting conveyor platform 2, and the telescopic structure of the tilting execution component 3 controls the tilting conveyor platform 2 to tilt along a specified direction and angle. The conveying tracks of the fixed-track conveyor platform 1 and the tilting conveyor platform 2 have the same height, and their direction of movement is the same as the loading and unloading direction of the workpieces. The tilting conveyor platform 2 is adjacent to the workbench of the next process. The workbench has a designated position for the workpiece to fall into. The tilting conveyor platform 2 tilts towards the workbench, and the position of the conveyor track of the tilting conveyor platform 2 matches the designated position for the workpiece to fall into the workbench. The bottom of the base 4 has multiple casters, which facilitates the movement and adjustment of the distance between the tilting conveyor platform 2 and the workbench of the next process, ensuring that the entire tilting conveyor platform 2 tilts to the designated position for the workpiece to fall into the workbench.

[0047] In this embodiment, the movement of the workpiece along the conveying tracks of the fixed-track conveyor platform 1 and the tilting conveyor platform 2 towards the worktable is the loading stroke, and the movement of the workpiece along the conveying tracks of the fixed-track conveyor platform 1 and the tilting conveyor platform 2 away from the worktable is the unloading stroke. During loading, the tilting execution component 3 controls the tilting conveyor platform 2 to tilt towards the worktable and to a vertical position. During unloading, the tilting conveyor platform 2 receives the processed workpiece, and the tilting execution component 3 controls the tilting conveyor platform 2 to tilt away from the worktable from a vertical position to a horizontal position. The workpiece is loaded onto the conveyor track of the fixed-rail conveyor platform 1 and conveyed onto the conveyor track of the tilting conveyor platform 2. The tilting execution component 3 controls the tilting conveyor platform 2, together with the workpiece, to tilt towards the worktable to a vertical position. The workpiece falls into the worktable. The tilting execution component 3 controls the tilting conveyor platform 2 to maintain a vertical position and move towards the fixed-rail conveyor platform 1 at a preset distance. After the workpiece is processed, the tilting execution component 3 controls the tilting conveyor platform 2 to move towards the worktable in a vertical position to a preset position. The tilting conveyor platform 2 receives the processed workpiece. The tilting execution component 3 controls the tilting conveyor platform 2 to tilt towards the fixed-rail conveyor platform 1 to a horizontal position. The workpiece conveyor tracks on the fixed-rail conveyor platform 1 and the tilting conveyor platform 2 are connected to each other. The processed workpiece is conveyed horizontally from the tilting conveyor platform 2 to the fixed-rail conveyor platform 1 to complete the unloading process.

[0048] The fixed-track conveyor platform 1 includes a roller 10, a non-powered roller 11, a sprocket and chain drive assembly 12, a roller seat 13, a discharge baffle 14, and a guide plate.

[0049] There are multiple rollers 10, non-powered rollers 11, and roller seats 13. Multiple roller seats 13 are symmetrically installed in multiple rows on the top surface of the base 4 along the workpiece movement direction. Each row has two roller seats 13, and each roller seat 13 has a roller installed at the same position. The two roller seats 13 are rotatably connected to the rollers 10 through the rollers. The multiple rows of rollers 10 are used for workpiece passage. There are two guide plates. Each guide plate is installed obliquely on the top of each row of roller seats 13. Multiple non-powered rollers 11 are fixed perpendicular to the guide plate along their axis and located inside the roller seats 13. The number of non-powered rollers 11 is the same as the number of roller seats 13. The non-powered rollers 11 are used to assist in guiding the workpiece movement above the multiple rows of rollers 10. The sprocket and chain drive assembly 12 includes sprockets, chains, and a conveyor motor. The outer side of each roller in a single row of roller seats 13 is connected to a sprocket via a connecting shaft. The chain is wound around the outer side of each sprocket. A guide gear is coaxially mounted on the outer side of one of the sprockets. The conveyor motor is fixedly mounted on the base 4. The output shaft of the conveyor motor is connected to a drive gear. The drive gear of the conveyor motor is located directly below the guide gear. The drive gear and guide gear are wound around the outer side of the drive gear and drive chain. The conveyor motor drives the drive gear to rotate, which in turn drives the guide gear and the sprocket connected to the guide gear to rotate. Under the drive of the chain, all the sprockets on the outer side of the single row of roller seats 13 rotate. The sprockets drive the roller 10 to rotate in the same direction as the output shaft of the conveyor motor. The conveyor motor has clockwise and counterclockwise rotation directions. The discharge baffle 14 is fixedly mounted on the top surface of the base 4 and adjacent to the outermost roller 10, used to prevent the workpiece from sliding down the conveyor track of the fixed-track conveyor platform 1.

[0050] Preferably, the non-powered roller 11 has a variety of height dimensions, and different specifications of non-powered roller 11 can be replaced to match workpieces of different specifications on the market.

[0051] like Figure 2 As shown, the tilting conveyor platform 2 includes a fixed fork arm 20, rollers, unpowered rollers, a sprocket and chain drive assembly, roller seats, guide plates, and a tilting conveyor platform base plate. The tilting conveyor platform 2 has the same structure as the fixed-rail conveyor platform 1. The difference between the tilting conveyor platform 2 and the fixed-rail conveyor platform 1 is that the tilting conveyor platform 2 has a discharge baffle 14 at the end along the feeding direction of the fixed-rail conveyor platform 1, and a fixed fork arm 20 at the front end along the feeding direction of the tilting conveyor platform 2. The rollers 10, sprocket and chain drive assembly 12, roller seats 13, and discharge baffle 14 of the fixed-rail conveyor platform 1 are fixedly installed on the base 4, while the fixed fork arm 20, rollers, sprocket and chain drive assembly, and roller seats of the tilting conveyor platform 2 are fixedly installed on the tilting conveyor platform base plate.

[0052] like Figure 3 , Figure 4 As shown, the fixed fork arm 20 is a U-shaped plate, which is fixed perpendicular to the edge of the bottom plate of the tilting conveyor platform, with its open end facing the top of the tilting conveyor platform 2. The top of the worktable B is a boss structure, and the opening of the U-shaped plate matches the boss structure of the worktable B. The bottom of the worktable B is driven by a lifting cylinder to move its top up and down.

[0053] Workpiece A moves on the tilting conveyor platform 2 toward worktable B until it comes into contact with the fixed fork arm 20. The tilting conveyor platform 2 stops conveying and tilts toward worktable B. The fixed fork arm 20 bears the weight of workpiece A, preventing workpiece A from tilting and sliding off the conveyor track, so that workpiece A is tilted to a vertical position. Worktable B moves upward through the lifting cylinder, so that the boss structure of worktable B passes through the opening of the fixed fork arm 20 and lifts workpiece A so that workpiece A falls on the boss structure of worktable B. The tilting execution component 3 controls the tilting conveyor platform 2 to move backward, and worktable B moves along its own track to the designated process.

[0054] Preferably, a limit switch is installed on the fixed fork arm 20. The limit switch is connected to the conveyor motor of the sprocket and chain drive assembly of the tilting conveyor platform 2 via a signal line. When the roller of the tilting conveyor platform 2 drives the workpiece to move to the front end of the conveyor track, the workpiece contacts the limit switch. The limit switch sends an electric shock action signal to the conveyor motor via the signal line, and the conveyor motor stops working upon receiving the signal.

[0055] like Figure 2 , Figure 5 As shown, the flipping actuator 3 includes a slide rail 30, a mounting plate 31, a pin cylinder 32, a piston rod pin 33, a pivot pin 34, a buffer 35, a forward / backward motor 36, a slider 37, a rack 38, a pin mounting base, and a mounting base connecting block.

[0056] The top surface of the base 4 has a rectangular slot. There are two slide rails 30, which are symmetrically fixed on both sides of the rectangular slot on the top surface of the base 4. The slide grooves of the two slide rails 30 are parallel to each other and are in the same direction as the conveying track of the tilting conveyor platform 2. Two sliders 37 are slidably connected to each slide rail 30. The mounting plate 31 is horizontally fixed on the top surface of the four sliders 37. The rack 38 is fixed on the top surface of the base 4 along the length of the slide rail 30 and is located below the mounting plate 31. The teeth of the rack 38 face the rectangular slot on the top surface of the base 4.

[0057] The mounting plate 31 has a cylinder mounting slot for the transmission of the pin-driven cylinder 32. The cylinder mounting slot of the mounting plate 31 is located directly above the rectangular slot on the top surface of the base 4. There are three pin mounting seats. One pin mounting seat and two mounting seat connecting blocks are fixedly installed on the bottom of the tilting conveyor platform base plate of the tilting conveyor platform 2. The other two pin mounting seats are symmetrically fixed on both sides of the front end of the cylinder mounting slot of the mounting plate 31 and are rotatably connected to the mounting seat connecting blocks of the tilting conveyor platform base plate through the pivot pin 34. The oil rod of the pin-driven cylinder 32 passes obliquely through the cylinder mounting slot of the mounting plate 31. The oil rod is rotatably connected to the pin mounting seat of the tilting conveyor platform base plate through the piston rod pin 33. The cylinder housing is fixedly installed on the bottom of the mounting plate 31 by a bracket. The extension and retraction of the pin-driven cylinder 32 drives the tilting conveyor platform 2 to tilt along the piston rod pin 33 and the pivot pin 34.

[0058] There are two buffers 35. The two buffers 35 are fixed on the top surface of the mounting plate 31 and located on the outside of the two pin mounting seats on the top surface of the mounting plate 31. The head of the buffer 35 faces the workpiece feeding and conveying direction. It is used to flip the flip conveyor platform 2 to a vertical position. The bottom plate of the flip conveyor platform contacts the two buffers 35 to buffer and prevent the workpiece on the flip conveyor platform 2 from shaking and falling.

[0059] Preferably, the buffer 35 adopts a spring limiting structure, with the head rod connected to the spring. The spring is installed inside the housing of the buffer 35, and the buffering is achieved by the compression of the spring.

[0060] The forward and reverse motor 36 is directly connected to the gear through a planetary reducer. The planetary reducer is fixed on the top surface of the mounting plate 31. The output shaft of the planetary reducer passes through the mounting plate 31 and is connected to the gear on the bottom surface of the mounting plate 31. The gear meshes horizontally with the rack 38. The forward and reverse motor 36 drives the planetary reducer to rotate the gear. The gear moves on the rack 38, causing the tilting conveyor platform 2 on the mounting plate 31 to move on the slide rail 30.

[0061] like Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 As shown, the working method of the loading and unloading mechanism of the present invention is as follows:

[0062] Step 1: The crane places the workpiece onto the conveyor track of the fixed-rail conveyor platform 1. Driven by the conveyor motor of the fixed-rail conveyor platform 1, the workpiece is conveyed to the conveyor track of the tilting conveyor platform 2. The workpiece moves until it comes into contact with the fixed fork arm 20. At this time, the workpiece also comes into contact with the limit switch, and the limit switch controls the conveyor track of the tilting conveyor platform 2 to stop rotating.

[0063] Step 2: The flipping execution component 3 flips the flipping conveyor platform 2 to a vertical position towards the worktable via the pin cylinder 32. At this time, the workpiece on the fixed fork arm 20 is located directly above the raised structure of the worktable. The raised structure of the worktable rises and passes through the opening on the fixed fork arm 20 to lift the workpiece and remove it from the fixed fork arm 20.

[0064] Step 3: The tilting conveyor platform 2 maintains a vertical posture, and the tilting execution component 3 controls the tilting conveyor platform 2 to move away from the worktable and back to the designated position of the slide rail 30 through the forward and backward motor 36.

[0065] Step 4: After the workpiece is processed, the flipping execution component 3 controls the fixed fork arm 20 of the flipping conveyor platform 2 to move towards the worktable until the protruding structure of the worktable is inserted. The protruding structure of the worktable descends and places the workpiece on its top onto the fixed fork arm 20.

[0066] Step 5: The flipping execution component 3 flips the flipping conveyor platform 2 to a horizontal position away from the worktable through the pin cylinder 32. At this time, the conveying track of the fixed track conveyor platform 1 and the conveying track of the flipping conveyor platform 2 are connected. The conveying motors of the fixed track conveyor platform 1 and the flipping conveyor platform 2 rotate synchronously towards the discharge baffle 14. When they rotate to contact the discharge baffle 14, the conveying motors stop working.

[0067] Step 6: The overhead crane removes the processed workpiece and proceeds to process the next workpiece. Repeat steps 1 to 5 until all workpieces have been loaded and unloaded.

[0068] The above descriptions are merely embodiments of the present invention, and common knowledge regarding specific structures and characteristics of the solutions is not described in detail here. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the present invention is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
