Description

Technical Field

[0001] The present application relates to the field of production equipment for photovoltaic cell modules, and more particularly to a sheet loading device. Background Art

[0002] During the production process of photovoltaic cell modules, silicon wafers in a basket need to be loaded onto a silicon wafer conveyor line one by one. The existing silicon wafer loading device only includes a basket transfer mechanism, which is used to move the basket containing silicon wafers to the input end of the silicon wafer conveyor line, so that the silicon wafers in the basket fall onto the silicon wafer conveyor line one by one.

[0003] After the silicon wafers in the basket are emptied, the transfer mechanism moves the emptied basket to the basket replacement station for basket replacement. In the existing silicon wafer loading device, when the transfer mechanism performs the basket replacement operation, the feeding interval time of the silicon wafer conveyor line is relatively long, resulting in a long feeding waiting time and reducing the feeding efficiency. Summary of the Utility Model

[0004] In order to solve the above technical problems, the present application provides a sheet loading device, which adopts the following technical solutions:

[0005] A sheet loading device includes a first basket conveyor line, a second basket conveyor line, a first handling mechanism, a second handling mechanism, a first flipping mechanism, a second flipping mechanism, a first transfer mechanism, a second transfer mechanism, and a sheet conveyor line, wherein:

[0006] The first basket conveyor line is configured to input a basket containing sheets placed in a horizontal state along a first horizontal direction. The first flipping mechanism is arranged at the output end of the first basket conveyor line. The first handling mechanism is configured to pick up the basket containing sheets from the first basket conveyor line and transport the basket containing sheets to the first flipping mechanism.

[0007] The first transfer mechanism and the second transfer mechanism are configured to alternately move to the side of the first flipping mechanism. The first flipping mechanism is configured to flip the basket containing sheets towards the first transfer mechanism or the second transfer mechanism, so that the basket containing sheets falls vertically onto the first transfer mechanism or the second transfer mechanism.

[0008] The first transfer mechanism and the second transfer mechanism are further configured to alternately move the basket containing sheets to the input end of the sheet conveyor line. The sheet conveyor line is configured to take out sheets from the basket one by one and transport the sheets to the subsequent process station.

[0009] The second flipping mechanism is arranged at the input end of the second basket conveying line. The first transfer mechanism and the second transfer mechanism are further configured to alternately move the emptied baskets to the side of the second flipping mechanism. The second flipping mechanism is configured to flip the emptied baskets to the horizontal state. The second handling mechanism is configured to pick up the emptied baskets after flipping from the second flipping mechanism and transport the emptied baskets to the second basket conveying line.

[0010] The second basket conveying line is configured to output the emptied baskets.

[0011] In the sheet loading device provided by the present application, the first transfer mechanism and the second transfer mechanism alternately load the sheets onto the sheet conveying line. In this way, when one of them is performing the basket changing operation, the other can continue to perform the normal loading of the sheet conveying line, preventing loading waiting and improving the loading efficiency.

[0012] In some embodiments, the first basket conveying line and the second basket conveying line are arranged side by side vertically, and the conveying direction of the second basket conveying line is opposite to that of the first basket conveying line; the first handling mechanism is located above the output end of the first basket conveying line; the second handling mechanism is located above the input end of the second basket conveying line.

[0013] The first basket conveying line and the second basket conveying line are arranged side by side vertically, greatly reducing the size and occupied space of the sheet loading device.

[0014] In some embodiments, the second handling mechanism has the same structure as the first handling mechanism. The first handling mechanism includes a first translation part, a first lifting part and a picking component. Among them, the first lifting part is connected to the moving part of the first translation part, and the picking component is connected to the moving part of the first lifting part; the first translation part is configured to drive the picking component to translate between the first basket conveying line and the first flipping mechanism, and the first lifting part is configured to drive the picking component to lift and lower, so as to drive the picking component to pick up the basket containing sheets from the first basket conveying line and transport the basket containing sheets to the first flipping mechanism.

[0015] Through the cooperative driving of the first translation part and the first lifting part, the picking component can translate between the first basket conveying line and the first flipping mechanism and lift and lower in the vertical direction, ensuring that the picking component can smoothly pick up the basket containing sheets from the first basket conveying line and transport the picked basket containing sheets to the first flipping mechanism.

[0016] In some embodiments, the first translation part includes a first mounting bracket, a cross beam, a synchronous belt, and a translation driving member. Among them, a guide rail is provided on the first mounting bracket. The synchronous belt is arranged on the first mounting bracket and is parallel to the guide rail. The cross beam is slidably connected to the guide rail, and the cross beam is fixedly connected to one side belt body of the synchronous belt. The translation driving member is configured to drive the synchronous belt to rotate so as to drive the cross beam to slide along the guide rail. The first lifting part includes a guide plate, a lifting bracket, and a lifting driving member. Among them, the guide plates are arranged in pairs on the cross beam, the lifting driving member is arranged on the cross beam, the lifting bracket is connected to the driving end of the lifting driving member, and both ends of the lifting bracket slide on the guide plates respectively. The lifting driving member is configured to drive the lifting bracket to lift and slide along the guide plates. The picking component is installed on the lifting bracket.

[0017] The synchronous belt driving method can drive the picking component to translate stably and can increase the translation stroke of the picking component. Since the guide plates realize the lifting guidance of the lifting bracket from both ends, the lifting smoothness of the picking component is ensured, and the material basket is prevented from tilting during picking and handling.

[0018] In some embodiments, the picking component includes a spacing driving member, a first claw, and a second claw. Among them: the spacing driving member is installed on the lifting bracket, the first claw and the second claw are connected to the driving end of the spacing driving member, and the spacing driving member is configured to drive the first claw and the second claw to separate from each other or move closer to the middle to hook or release the material basket.

[0019] Driven by the spacing driving member, the first claw and the second claw hook the material basket from both ends, so as to ensure that the material box can be hooked tightly and ensure that the material basket remains horizontal during movement.

[0020] In some embodiments, the structure of the second flipping mechanism is the same as that of the first flipping mechanism. The first flipping mechanism includes a rotation driving part, a bearing frame, and a first clamping part. Among them: the bearing frame is connected to the driving end of the rotation driving part, and the rotation driving part is configured to drive the bearing frame to flip and switch between a horizontal state and a vertical state; the first clamping part is arranged on the bearing frame, and the first clamping part is configured to clamp and position the material basket on the bearing frame.

[0021] Through the cooperation of the rotation driving part, the bearing frame, and the first clamping part, the first flipping mechanism realizes the clamping and rotation of the material basket.

[0022] In some embodiments, the structure of the second transfer mechanism is the same as that of the first transfer mechanism. The first transfer mechanism includes a second translation part, a second lifting part, a mounting seat, and a carrying platform, where: the second lifting part is connected to the moving part of the second translation part, the mounting seat is connected to the moving part of the second lifting part, and the carrying platform is arranged on the mounting seat; the carrying platform is configured to carry the basket, the second translation part is configured to drive the carrying platform to translate along a first horizontal direction towards the first flipping mechanism, the second flipping mechanism, or the sheet conveying line, and the second lifting part is configured to drive the carrying platform to lift and lower.

[0023] Through the cooperative driving of the second translation part and the second lifting part, the carrying platform can translate between the first flipping mechanism, the second flipping mechanism, and the sheet conveying line, and lift and lower in the vertical direction, ultimately ensuring that the carrying platform can receive the basket containing the sheets flipped and dropped from the first flipping mechanism, and move the basket containing the sheets to the input end of the sheet conveying line, and enabling the sheets to fall onto the sheet conveying line one by one from top to bottom.

[0024] In some embodiments, the carrying platform is slidably connected to the mounting seat. The first transfer mechanism further includes a third translation part arranged on the mounting seat. The third translation part is configured to drive the carrying platform to slide along a second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction. The basket includes one receiving cavity or two receiving cavities. When the basket includes two receiving cavities, the two receiving cavities in the basket located on the carrying platform are arranged side by side along the second horizontal direction. When the third translation part drives the carrying platform to slide along the second horizontal direction, it is configured to drive the two receiving cavities to be respectively docked with the sheet conveying line.

[0025] When the basket includes one or two receiving cavities, the third translation part drives the carrying platform to slide along the second horizontal direction, so that the receiving cavities in the basket can be docked with the sheet conveying line, thereby improving the compatibility of the silicon wafer loading device of the present application with different baskets.

[0026] In some embodiments, the first transfer mechanism further includes a second clamping part arranged on the carrying platform. The second clamping part is configured to clamp and position the basket on the carrying platform.

[0027] By arranging the second clamping part, the basket is clamped and positioned on the carrying platform, preventing the basket from sliding and generating a position offset during the movement.

[0028] In some embodiments, a stop block is arranged at the end of the carrying platform far from the second lifting part. The second clamping part includes a second mounting bracket, a pushing component, and a pressing component, where: the second mounting bracket is arranged on the carrying platform; the pushing component is arranged on the second mounting bracket, and the pushing component is configured to push the basket towards the stop block to cooperate with the stop block to press the bottom of the basket; the pressing component is arranged on the second mounting bracket, and the pressing component is configured to press the top of the basket downwards.

[0029] Through the cooperation of the pushing component and the pressing component, the second clamping part realizes the pressing of the bottom and the top of the material basket, thereby ensuring that the material basket is clamped and positioned on the carrier table.

[0030] In some embodiments, when the material basket on the carrier table of the first transfer mechanism releases the sheet body to the input end of the sheet body conveying line, the carrier table of the second transfer mechanism drives the material basket loaded with the sheet body to move directly above the carrier table of the first transfer mechanism; during the process of the material basket on the carrier table of the first transfer mechanism releasing the sheet body to the input end of the sheet body conveying line, the carrier table of the second transfer mechanism gradually descends; after the material basket on the carrier table of the first transfer mechanism finishes releasing all the sheet bodies in the current storage cavity, the carrier table of the second transfer mechanism descends to the release position to release the sheet body to the input end of the sheet body conveying line.

[0031] The sheet body conveying line realizes the continuous and cyclic picking of the sheet bodies in the first material basket on the first transfer mechanism and the second material basket on the second transfer mechanism, thereby further improving the sheet body loading efficiency.

[0051] To make the above objects, features, and advantages of the present application more obvious and understandable, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0052] As Figure 1 shown, the wafer loading device in the embodiment of the present application includes the first basket conveyor line 1, the second basket conveyor line 2, the first handling mechanism 3, the second handling mechanism 4, the first flipping mechanism 5, the second flipping mechanism 6, the first transfer mechanism 7, the second transfer mechanism 8, and the sheet conveyor line 9, wherein:

[0053] The first basket conveyor line 1 is configured to input a basket containing wafers placed in a horizontal state along the first horizontal direction (such as the X-axis direction). The first flipping mechanism 5 is arranged at the output end of the first basket conveyor line 1. The first handling mechanism 3 is configured to pick up the basket containing wafers from the first basket conveyor line 1 and transport the basket containing wafers to the first flipping mechanism 5.

[0054] The first transfer mechanism 7 and the second transfer mechanism 8 are configured to alternately move to the side of the first flipping mechanism 5. The first flipping mechanism 5 is configured to flip the basket containing the sheets towards the first transfer mechanism 7 or the second transfer mechanism 8, so that the basket containing the sheets falls vertically onto the first transfer mechanism 7 or the second transfer mechanism 8. At this time, the sheets on the first transfer mechanism 7 or the second transfer mechanism 8 are stacked layer by layer in the basket in the vertical direction, and the sheets are all in a horizontal state.

[0055] The first transfer mechanism 7 and the second transfer mechanism 8 are further configured to alternately move the basket containing the sheets to the input end of the sheet conveying line 9. The sheet conveying line 9 is configured to pick up the sheets one by one from the basket and convey the sheets to the subsequent process station.

[0056] The second flipping mechanism 6 is arranged at the input end of the second basket conveying line 2. The first transfer mechanism 7 and the second transfer mechanism 8 are further configured to alternately move the emptied basket to the side of the second flipping mechanism 6. The second flipping mechanism 6 is configured to flip the emptied basket to the horizontal state. The second handling mechanism 4 is configured to pick up the emptied basket after flipping from the second flipping mechanism 6 and convey the emptied basket to the second basket conveying line 2.

[0057] The second basket conveying line 2 is configured to output the emptied basket.

[0058] It can be seen that in the sheet loading device provided by the embodiment of the present application, the first transfer mechanism 7 and the second transfer mechanism 8 can alternately load the sheets onto the sheet conveying line 9. In this way, when one of them is performing the basket changing operation, the other can continue to perform the normal feeding of the sheet conveying line 9, preventing the occurrence of feeding waiting and improving the feeding efficiency.

[0059] The sheet loading device of the embodiment of the present application is suitable for loading the silicon wafers in the basket onto the silicon wafer conveying line. In this application scenario, the sheet is a silicon wafer and the sheet conveying line is a silicon wafer conveying line. Of course, the sheet loading device provided by the embodiment of the present application is also suitable for loading other types of sheet-like articles.

[0060] As Figure 1 shown, optionally, the first basket conveying line 1 and the second basket conveying line 2 are arranged side by side vertically, and the conveying direction of the second basket conveying line 2 is opposite to that of the first basket conveying line 1. The first handling mechanism 3 is located above the output end of the first basket conveying line 1. The second handling mechanism 4 is located above the input end of the second basket conveying line 2.

[0061] The first basket conveying line 1 and the second basket conveying line 2 are arranged side by side vertically, so that the size and occupied space of the sheet loading device in the embodiment of the present application are greatly reduced.

[0062] Optionally, the second handling mechanism 4 has the same structure as the first handling mechanism 3. As Figure 2 shown, taking the first handling mechanism 3 as an example, it includes a first translation part 31, a first lifting part 32 and a picking component 33. Among them, the first lifting part 32 is connected to the moving part of the first translation part 31, and the picking component 33 is connected to the moving part of the first lifting part 32. The first translation part 31 is configured to drive the picking component 33 to translate between the first basket conveyor line 1 and the first turning mechanism 5, and the first lifting part 32 is configured to drive the picking component 33 to lift, so as to drive the picking component 33 to pick up the basket containing the sheet body from the first basket conveyor line 1 and transport the basket containing the sheet body to the first turning mechanism 5.

[0063] As Figure 2 shown, optionally, the first translation part 31 includes a first mounting bracket 311, a cross beam 312, a synchronous belt 313 and a translation driving part 314. Among them, a guide rail is provided on the first mounting bracket 311, the synchronous belt 313 is arranged on the first mounting bracket 311 and is parallel to the guide rail, the cross beam 312 is slidably connected to the guide rail, the cross beam 312 is fixedly connected to one side belt body (such as the upper side belt body) of the synchronous belt 313, and the translation driving part 314 selects a motor. The translation driving part 314 is configured to drive the synchronous belt 313 to rotate, so as to drive the cross beam 312 to slide along the guide rail. The synchronous belt driving method can drive the picking component 33 to translate stably and can increase the translation stroke of the picking component 33.

[0064] Of course, the first translation part 31 can also adopt a linear driving module with other structures that can drive the picking component 33 to translate between the first basket conveyor line 1 and the first turning mechanism 5.

[0065] Optionally, the first lifting part 32 includes a guide plate 321, a lifting bracket 322 and a lifting driving part 323. Among them, the guide plates 321 are arranged in pairs on the cross beam 312, the lifting driving part 323 is arranged on the cross beam 312, the lifting bracket 322 is connected to the driving end of the lifting driving part 323, and both ends of the lifting bracket 322 slide on the guide plates 321 respectively. The lifting driving part 323 is configured to drive the lifting bracket 322 to lift and slide along the guide plates 321, and the picking component 33 is installed on the lifting bracket 322. Since the guide plates 321 guide the lifting of the lifting bracket 322 from both ends, the lifting smoothness of the picking component 33 is ensured, and the basket is prevented from tilting during the picking and handling process.

[0066] The lifting driving part 323 can select an electric cylinder. Of course, the first lifting part 32 can also adopt a linear driving module with other structures that can drive the picking component 33 to lift.

[0067] As Figure 3As shown, optionally, the picking component 33 includes a spacing driving member 331, a first hook 332, and a second hook 333, where: the spacing driving member 331 is installed on the lifting bracket 322, the first hook 332 and the second hook 333 are connected to the driving end of the spacing driving member 331, and the spacing driving member 331 is configured to drive the first hook 332 and the second hook 333 to separate from each other or approach each other in the middle to hook or release the basket. Driven by the spacing driving member 331, the first hook 332 and the second hook 333 hook the basket from both ends, thereby ensuring that the cartridge can be tightly hooked and ensuring that the basket remains horizontal during movement.

[0068] Optionally, the structure of the second flipping mechanism 6 is the same as that of the first flipping mechanism 5. As Figures 4 to 5 shown, taking the first flipping mechanism 5 as an example, it includes a rotation driving part 51, a carrier 52, and a first clamping part, where: the carrier 52 is connected to the driving end of the rotation driving part 51, and the rotation driving part 51 is configured to drive the carrier 52 to flip and switch between a horizontal state and a vertical state. The first clamping part is arranged on the carrier 52, and the first clamping part is configured to clamp and position the basket 100 on the carrier 52.

[0069] Optionally, the rotation driving part 51 uses a motor, that is, the carrier 52 and the basket thereon are driven to rotate by the motor. The first clamping part includes a pressing mechanism 53 and a support member 54 installed on the carrier 52. The pressing mechanism 53 includes a cylinder and a pressing plate fixed to the end of the piston rod of the cylinder. When the basket is placed vertically on the carrier 52, the lower end of the basket is placed on the support member 54, and the upper end of the basket is pressed by the pressing plate, so as to realize the fixed clamping of the basket.

[0070] The working process of the first flipping mechanism 5 is as follows:

[0071] First, the rotation driving part 51 drives the carrier 52 to the horizontal state, and controls the pressing plate to move to the initial position away from the support member 54 through the cylinder.

[0072] After the first handling mechanism 3 transports the basket 100 filled with sheets picked up from the first conveyor line 1 to the carrier 52, control the cylinder to drive the pressing plate to move towards the support member 54 to clamp the basket.

[0073] When the first transfer mechanism 7 or the second transfer mechanism 8 moves to the side of the first flipping mechanism 5, the rotation driving part 51 drives the carrier 52 to the vertical state, so that the basket 100 falls to the first transfer mechanism 7 or the second transfer mechanism 8 in a vertical state. At the same time, drive the pressing plate away from the basket through the cylinder to release the basket.

[0074] Optionally, the structure of the second transfer mechanism 8 is the same as that of the first transfer mechanism 7. As Figure 6As shown, taking the first transfer mechanism 7 as an example, it includes a second translation part 71, a second lifting part 72, a mounting seat 73 and a carrying platform 74, where: the second lifting part 72 is connected to the moving part of the second translation part 71, the mounting seat 73 is connected to the moving part of the second lifting part 72, and the carrying platform 74 is arranged on the mounting seat 73. The carrying platform 74 is configured to carry the basket, the second translation part 71 is configured to drive the carrying platform 74 to translate along the first horizontal direction towards the first flipping mechanism 5, the second flipping mechanism 6 or the sheet conveying line 9, and the second lifting part 72 is configured to drive the carrying platform 74 to lift and lower.

[0075] The optional working process of the first transfer mechanism 7 is as follows:

[0076] The second lifting part 72 drives the carrying platform 74 to lift and lower, so that the carrying platform 74 is aligned with the first flipping mechanism 5, and the second translation part 71 drives the carrying platform 74 to move to the side of the first flipping mechanism 5. In this way, it can be ensured that when the first flipping mechanism 5 flips the basket containing the sheets towards the carrying platform 74, the basket containing the sheets falls onto the carrying platform 74 in a vertical state.

[0077] Subsequently, the second lifting part 72 drives the carrying platform 74 to lift and lower, so that the basket is aligned with the sheet conveying line 9. The second translation part 71 drives the carrying platform 74 to move towards the sheet conveying line 9 until the sheet conveying line 9 is inserted into the basket.

[0078] Then, the second lifting part 72 drives the carrying platform 74 and the basket to descend, so that the sheets in the basket can fall onto the sheet conveying line 9 in sequence, and are taken out by the sheet conveying line 9 in sequence and then conveyed to the subsequent working station.

[0079] When the basket is emptied, the second translation part 71 drives the carrying platform 74 to move away from the sheet conveying line 9, so that the sheet conveying line 9 is withdrawn from the emptied basket. Subsequently, the second lifting part 72 controls the lifting and lowering of the carrying platform 74, so that the carrying platform 74 is aligned with the second flipping mechanism 6.

[0080] The carrier of the second flipping mechanism 6 flips into a vertical state to wait for receiving the emptied basket.

[0081] The second translation part 71 drives the carrying platform 74 to move to the side of the second flipping mechanism 6, so that the support in the second flipping mechanism 6 is inserted under the emptied basket on the carrying platform 74, and the empty basket on the carrying platform 74 is pressed by the pressing plate in the second flipping mechanism 6. The empty basket on the carrying platform 74 is then clamped by the first clamping part in the second flipping mechanism 6. In this way, the empty basket enters the second flipping mechanism 6, and the second flipping mechanism 6 flips the empty basket into a horizontal shape.

[0082] Still taking the first transfer mechanism 7 as an example, as Figure 7As shown, optionally, the carrier table 74 is slidably connected to the mounting base 73. A third translation part 75 is further provided on the mounting base 73. The third translation part 75 is configured to drive the carrier table 74 to slide along the second horizontal direction (such as the Y-axis direction), and the second horizontal direction is perpendicular to the first horizontal direction. The basket includes one storage cavity or two storage cavities.

[0083] When the basket only includes one storage cavity, the third translation part 75 drives the carrier table 74 to slide along the second horizontal direction, so that the storage cavity can be docked with the sheet conveying line 9, enabling the sheet conveying line 9 to take out the sheets in the storage cavity.

[0084] When the basket includes two storage cavities, the two storage cavities in the basket located on the carrier table 74 are arranged side by side along the second horizontal direction. When the third translation part 75 drives the carrier table 74 to slide along the second horizontal direction, the two storage cavities can be respectively docked with the sheet conveying line 9, enabling the sheet conveying line 9 to take out the sheets in the two storage cavities successively.

[0085] As Figure 7 and Figure 8 As shown, optionally, the first transfer mechanism 7 further includes a second clamping part 77 provided on the carrier table 74. The second clamping part 77 is configured to clamp and position the basket on the carrier table 74 to prevent the basket from sliding during movement and causing position deviation.

[0086] Optionally, a stop block 76 is provided at the end of the carrier table 74 away from the second lifting part 72. The second clamping part 77 includes a second mounting bracket 771, a pushing component 772 and a pressing component 773, where: the second mounting bracket 771 is provided on the carrier table 74. The pushing component 772 and the pressing component 773 are both provided on the second mounting bracket 771. After the basket falls onto the carrier table 74, the pushing component 772 is configured to push the basket towards the stop block 76 to cooperate with the stop block 76 to press the bottom of the basket. At the same time, the pressing component 773 is configured to press down the top of the basket.

[0087] Optionally, when the basket on the carrier table 74 of the first transfer mechanism 7 releases sheets to the input end of the sheet conveying line 9, the carrier table 74 of the second transfer mechanism 8 drives the basket loaded with sheets to move directly above the carrier table 74 of the first transfer mechanism 7. During the process of the basket on the carrier table 74 of the first transfer mechanism 7 releasing sheets to the input end of the sheet conveying line 9, the carrier table of the second transfer mechanism 8 gradually descends. After the basket on the carrier table 74 of the first transfer mechanism 7 finishes releasing all the sheets in the current storage cavity, the carrier table 74 of the second transfer mechanism 8 descends to the release position to release sheets to the input end of the sheet conveying line 9.

[0088] For a material basket with only one storage cavity, the optional feeding process of the first transfer mechanism 7 and the second transfer mechanism 8 is as follows:

[0089] The first transfer mechanism 7 drives the first material basket located thereon to lift and translate, so that the input end of the sheet conveying line 9 is inserted into the storage cavity of the first material basket. Subsequently, the first transfer mechanism 7 drives the first material basket to descend, so that the sheets in the first material basket fall onto the input end of the sheet conveying line 9 in sequence and are taken out by the sheet conveying line 9.

[0090] The second transfer mechanism 8 drives the second material basket located thereon to lift and translate, so that the second material basket on the second transfer mechanism 8 moves above the first material basket and ensures that the storage cavity of the second material basket is vertically aligned with the storage cavity of the first material basket.

[0091] While the first material basket descends to release the sheets, the second material basket also descends synchronously.

[0092] When the sheets in the first material basket are emptied, the first transfer mechanism 7 drives the first material basket away from the input end of the sheet conveying line 9. The second material basket continues to descend, so that the input end of the sheet conveying line 9 is inserted into the storage cavity of the second material basket. Subsequently, the second transfer mechanism 8 drives the second material basket to descend, so that the sheets in the second material basket fall onto the input end of the sheet conveying line 9 in sequence and are taken out by the sheet conveying line 9.

[0093] After the first transfer mechanism 7 completes the basket-changing operation and obtains a new first material basket filled with sheets, the first transfer mechanism 7 drives the first material basket located thereon to move, so that the first material basket moves above the second material basket that is currently releasing sheets and ensures that the storage cavity of the first material basket is vertically aligned with the storage cavity of the second material basket.

[0094] It can be seen that the sheet conveying line 9 also realizes continuous and cyclic sheet taking from the first material basket with only one storage cavity on the first transfer mechanism 7 and the second material basket with only one storage cavity on the second transfer mechanism 8, thereby improving the sheet feeding efficiency.

[0095] In summary, when one of the material baskets releases sheets, the other material basket filled with sheets will descend synchronously above it to wait for replacement. The distance between the two material baskets is very short. When one of the material baskets is emptied, the other material basket filled with sheets only needs to descend a very short distance to be in place for replacement and continue to release sheets. Therefore, the basket-changing time is very short and the efficiency is very high. To make the turnover efficiency of the material baskets higher, when arranging, the center lines (along the conveying direction) of the first material basket conveying line 1, the second material basket conveying line 2 and the sheet conveying line 9 are collinear in the projection on the same horizontal plane. In this way, the two carrier platforms 74 drive the material baskets thereon to rotate counterclockwise or clockwise in the vertical plane, which can also save the width of the entire wafer feeding device (the width is perpendicular to the conveying direction).

[0096] For a material basket with two storage cavities, the optional feeding process of the first transfer mechanism 7 and the second transfer mechanism 8 is as follows:

[0097] The first transfer mechanism 7 drives the first material basket with sheets in both of its two storage cavities to lift and translate, so that the input end of the sheet conveyor line 9 is inserted into the first storage cavity of the first material basket. Subsequently, the first transfer mechanism 7 drives the first material basket to descend, so that the sheets in the first storage cavity of the first material basket fall onto the input end of the sheet conveyor line 9 in sequence and are taken out by the sheet conveyor line 9.

[0098] The second transfer mechanism 8 drives the second material basket with sheets in both of its two storage cavities to lift and translate, so that the second material basket on the second transfer mechanism 8 moves above the first material basket, and it is ensured that the first storage cavity of the second material basket is aligned with the first storage cavity of the first material basket vertically, the second storage cavity of the second material basket is aligned with the second storage cavity of the first material basket vertically, and the second material basket and the first material basket descend synchronously.

[0099] When the sheets in the first storage cavity of the first material basket are emptied, the first transfer mechanism 7 drives the first material basket away from the input end of the sheet conveyor line 9, and the second material basket continues to descend, so that the input end of the sheet conveyor line 9 is inserted into the first storage cavity of the second material basket. Subsequently, the second transfer mechanism 8 drives the second material basket to descend, so that the sheets in the first storage cavity of the second material basket fall onto the input end of the sheet conveyor line 9 in sequence and are taken out by the sheet conveyor line 9.

[0100] Meanwhile, the first transfer mechanism 7 drives the first material basket to rise and translate, and the third translation part 75 in the first transfer mechanism 7 drives the carrier table 74 to slide along the second horizontal direction, so that the first material basket moves above the second material basket that is currently releasing sheets, and it is ensured that the second storage cavity of the first material basket is aligned with the first storage cavity of the second material basket vertically.

[0101] When the sheets in the first storage cavity of the second material basket are emptied, the second transfer mechanism 8 drives the second material basket away from the input end of the sheet conveyor line 9, and the first material basket continues to descend, so that the input end of the sheet conveyor line 9 is inserted into the second storage cavity of the first material basket. Subsequently, the first transfer mechanism 7 drives the first material basket to descend, so that the sheets in the second storage cavity of the first material basket fall onto the input end of the sheet conveyor line 9 in sequence and are taken out by the sheet conveyor line 9.

[0102] Meanwhile, the second transfer mechanism 8 drives the second material basket to rise and translate, and the third translation part 75 in the second transfer mechanism 8 drives the carrier table 74 to slide along the second horizontal direction, so that the second material basket moves above the first material basket that is currently releasing sheets, and it is ensured that the second storage cavity of the second material basket is aligned with the second storage cavity of the first material basket vertically.

[0103] After the sheets in the second storage cavity of the first material basket are emptied, the first transfer mechanism 7 drives the first material basket away from the input end of the sheet conveying line 9 and moves towards the second flipping mechanism 6 to perform the basket-changing operation. The second material basket continues to descend, so that the input end of the sheet conveying line 9 is inserted into the second storage cavity of the second material basket, and the sheets in the second storage cavity of the second material basket are taken away by the sheet conveying line 9.

[0104] After the first transfer mechanism 7 completes the basket-changing operation and obtains a new first material basket filled with sheets, the first transfer mechanism 7 drives the first material basket located thereon to move, so that the first material basket on the first transfer mechanism 7 moves above the second material basket that is currently discharging sheets, and it is ensured that the first storage cavity of the first material basket is vertically aligned with the second storage cavity of the second material basket.

[0105] It can be seen that the sheet conveying line 9 also realizes the continuous and cyclic sheet taking of the sheets in the first material basket with two storage cavities on the first transfer mechanism 7 and the second material basket with two storage cavities on the second transfer mechanism 8, thereby improving the sheet loading efficiency.
