Description

Technical Field

[0001] This application relates to the field of photovoltaic cell module production equipment, specifically a material box carrying mechanism and a cell receiving device. Background Technology

[0002] The processed silicon wafers are transported via a silicon wafer conveyor line. During the transport process, the wafer receiving mechanism picks up the silicon wafers from the silicon wafer conveyor line and collects them into the cassette located on the cassette carrying mechanism.

[0003] The wafer receiving mechanism typically uses an adsorption conveyor line positioned above the wafer conveyor line and the cassette carrying mechanism. After the adsorption conveyor line picks up the wafers from the wafer conveyor line, it transports the wafers to the top of the cassette carrying mechanism and then releases the wafers, allowing them to fall into the cassette.

[0004] To ensure that the silicon wafers collected in the cassette are neatly stacked, the cassette is placed at an angle on the cassette carrying mechanism. After the cassette is full of silicon wafers, the cassette is removed from the carrying mechanism by the cassette transport hooks. Because the cassette is tilted when full of silicon wafers and is quite heavy, the cassette transport hooks have difficulty securing the cassette, increasing the difficulty of handling it. Utility Model Content

[0005] To solve the above-mentioned technical problems, this application provides a material box carrying mechanism, which adopts the following technical solution:

[0006] A material box carrying mechanism includes a mounting bracket, a material box carrying frame, a lifting arm, and a lifting block, wherein:

[0007] The material box support frame includes a sliding connecting bracket, a support bracket, and several supporting components. The sliding connecting bracket is slidably connected to the mounting bracket and can slide and switch between the receiving station and the box changing station along a first direction. The first corner of the support bracket is hinged to the sliding connecting bracket, and the second corner of the support bracket is inclined downward. The first corner and the second corner are two opposite corners of the support bracket. Several supporting components are arranged on the sliding connecting bracket, and the support bracket is supported on the several supporting components. The support bracket is used to carry the material box.

[0008] The first end of the lifting arm is connected to the second corner of the support bracket, and the second end of the lifting arm extends outward;

[0009] The lifting block is set on the side of the material box support frame and located below the lifting arm. The lifting block has a lifting slope and a supporting plane formed along the first direction. The supporting plane is connected to the top of the lifting slope.

[0010] When the sliding connecting bracket slides from the receiving station toward the box changing station, the second end of the lifting arm slides upwards onto the support plane via the lifting ramp, and the bearing bracket switches to a horizontal state under the lifting of the lifting arm.

[0011] During the sheet collection process, the sliding connecting bracket is located at the receiving station, and the supporting bracket is in an inclined state. Therefore, the material box on the supporting bracket is also in an inclined state, ensuring that the sheets collected into the material box are neatly stacked inside. After the sheet collection is complete, the sliding connecting bracket slides to the box changing station. During this process, the second end of the lifting arm slides upwards along the lifting ramp of the lifting block to the support plane of the lifting block. The supporting bracket is then lifted to a horizontal state, automatically adjusting the material box filled with sheets to a horizontal state, ultimately enabling the material box transport hook to smoothly transport the material box.

[0012] In some embodiments, a roller is provided at the second end of the lifting arm, and the second end of the lifting arm rolls onto the lifting ramp and the support plane via the roller.

[0013] By installing rollers at the second end of the lifting arm, the friction between the second end of the lifting arm and the lifting ramp and support plane of the lifting block can be reduced, allowing the second end of the lifting arm to smoothly slide upwards onto the support plane via the lifting ramp, thereby achieving stable lifting and leveling of the support bracket and the material box on it, preventing the material box from shaking and damaging the material sheet.

[0014] In some embodiments, the support assembly includes a bolt mounting base and a bolt, wherein: the bolt mounting base is fixedly mounted on the sliding connection bracket; the bolt is adjustablely screwed onto the bolt mounting base, and the load-bearing bracket is supported on the bolt.

[0015] By configuring the support assembly to include bolt mounting seats and bolts, the support assembly can adjust the angle of the load-bearing bracket, ensuring that the load-bearing bracket can switch to a horizontal state after the second end of the lifting arm slides onto the support plane.

[0016] In some embodiments, the material box carrying mechanism further includes a first translation drive component disposed on the mounting bracket and drivenly connected to the sliding connection bracket, the first translation drive component being used to drive the sliding connection bracket to slide and switch between the receiving station and the box changing station along a first direction.

[0017] By setting the first translation drive component, the translation drive of the sliding connecting bracket is realized, so that the sliding connecting bracket can automatically slide and switch between the receiving station and the box changing station along the first direction.

[0018] In some embodiments, the material box located on the support bracket has two storage cavities arranged side by side along a first direction. A tray is provided inside the material box, with a first half of the tray located in one of the storage cavities and a second half of the tray located in the other storage cavity. A lifting channel is provided on the sliding connecting bracket and the support bracket, and a lifting hole is provided at the bottom of the material box that communicates with the lifting channel. The material box carrying mechanism also includes a lifting assembly disposed below the sliding connecting bracket. The lifting assembly is configured to lift the tray to the high position for receiving the sheet via the lifting channel and the lifting hole. The lifting assembly is also configured to drive the tray to descend during the receiving process.

[0019] Because the cassette located on the support bracket has two storage cavities arranged side by side along the first direction, the sheet receiving mechanism can alternately receive the sheets onto the first and second halves of the tray. During the receiving process, the lifting assembly drives the tray to descend, ultimately ensuring that both storage cavities of the cassette are filled with sheets. This increases the amount of sheets received each time, reduces the frequency of cassette changes, and thus improves receiving efficiency.

[0020] In some embodiments, the material box carrying mechanism further includes a first air blowing component and a second air blowing component disposed on the mounting bracket; when the sliding connection bracket is located at the receiving station, the first air blowing component is configured to blow air into one of the receiving cavities of the material box to straighten the material pieces in one of the receiving cavities, and the second air blowing component is configured to blow air into the other receiving cavity of the material box to straighten the material pieces in the other receiving cavity.

[0021] The first and second air blowing components respectively straighten the material sheets placed in the two storage cavities of the material box, further improving the neatness of the stacked material sheets.

[0022] In some embodiments, a baffle plate is also provided between the two storage cavities of the material box.

[0023] This ensures that the airflow from the first and second air-blowing components only regulates the material pieces in the corresponding storage chambers and does not interfere with the material pieces in the other storage chamber.

[0024] In some embodiments, the material box carrying mechanism further includes a guide mechanism located above the material box carrying frame. The guide mechanism includes a first baffle and a second baffle, wherein: the surface of the first baffle extends along a first direction, the surface of the second baffle extends along a second direction, and the second direction is perpendicular to the first direction; when the sliding connection bracket is located at the receiving station, the surface of the first baffle is aligned with the first inner wall of the material box, and the surface of the second baffle is aligned with the second inner wall of the material box.

[0025] By setting up a guiding mechanism consisting of a first baffle and a second baffle, the falling material is guided, allowing the material to fall more smoothly onto the first and second halves of the pallet.

[0026] In some embodiments, the material box carrying mechanism further includes a second translation drive component and a third translation drive component, wherein: the second translation drive component is driven to the first baffle and is used to drive the first baffle to translate along a second direction; the third translation drive component is driven to the second baffle and is used to drive the second baffle to translate along a first direction.

[0027] When the sliding connecting bracket slides to the receiving station, the second translation drive assembly drives the first baffle to translate along the second direction, thereby adjusting the position of the first baffle to ensure that the surface of the first baffle is aligned with the inner wall of the first side of the material box. The third translation drive assembly then drives the second baffle to translate along the first direction, thereby adjusting the position of the second baffle to ensure that the surface of the second baffle is aligned with the inner wall of the second side of the material box.

[0028] In some embodiments, the material box carrying mechanism further includes a lifting drive assembly, which is connected to the first baffle in a transmission manner. The lifting drive assembly is used to drive the first baffle to rise and fall. When the first baffle rises to a high position, the lower end of the first baffle is higher than the top of the material box. When the first baffle falls to a low position, the lower end of the first baffle is lower than the top of the material box.

[0029] During the sheet collection process, the first baffle descends to a low position to guide the sheets. When the sheet cassette is full and a cassette change operation is required, the first baffle rises to a high position to avoid obstructing the sheet cassette.

[0030] This application also provides a sheet receiving device, which includes a sheet receiving mechanism and a cassette carrying mechanism as described in any of the above claims, wherein: the sheet receiving mechanism is disposed above the cassette carrying frame, and the sheet receiving mechanism is configured to convey and release the sheet into a cassette located on a carrying support.

[0031] Through the cooperation of the cassette carrying mechanism and the sheet receiving mechanism, the sheet receiving device of this application can automatically receive the sheets into the cassette located on the cassette carrying mechanism. In addition, the cassette is tilted during the sheet receiving process, thereby ensuring that the sheets received into the cassette can be neatly stacked in the cassette. The cassette full of sheets is automatically adjusted to a horizontal state, thereby ensuring that the cassette transport hook can smoothly transport the cassette. Attached Figure Description

[0052] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0053] Figures 1 to 3 The image shows a hopper carrying mechanism in an embodiment of this application. Figures 4 to 5The illustration shows a material box carrying mechanism carrying a material box in an embodiment of this application.

[0054] like Figures 1 to 5 As shown, the material box carrying mechanism in this embodiment includes a mounting bracket 1, a material box carrying frame 2, a lifting arm 3, and a lifting block 4, wherein:

[0055] The material box support frame 2 includes a sliding connecting bracket 21, a support bracket 22, and several support components 23. The sliding connecting bracket 21 is slidably connected to the mounting bracket 1 and can slide between the receiving station and the box changing station along a first direction (e.g., the X direction). The first corner of the support bracket 22 is hinged to the sliding connecting bracket 21, and the second corner of the support bracket 22 is downwardly inclined. The first and second corners are two opposite diagonals of the support bracket 22. Several support components 23 are disposed on the sliding connecting bracket 21, and the support bracket 22 is supported on the several support components 23. The support bracket 22 is used to support the material box 100.

[0056] The first end of the lifting arm 3 is connected to the second corner of the support bracket 22, and the second end of the lifting arm 3 extends out.

[0057] The lifting block 4 is set on the side of the material box support frame 2 and located below the lifting arm 3. The lifting block 4 has a lifting slope 41 and a support plane 44 formed along the first direction. The support plane 44 is connected to the top of the lifting slope.

[0058] When the sliding connecting bracket 21 slides from the receiving station toward the box changing station, the second end of the lifting arm 3 slides upwards onto the supporting plane 42 via the lifting ramp 41, and the bearing bracket 22 switches to a horizontal state under the lifting of the lifting arm 3.

[0059] like Figure 1 and Figure 4 As shown, during the receiving process, the sliding connecting bracket 21 is located at the receiving station. At this time, the bearing bracket 22 is tilted downwards towards its second corner. Therefore, the material box 100 on the bearing bracket 22 is also tilted, so that the material box 100 is also tilted downwards towards one of its corners. This ensures that the material pieces 200 received in the material box can slide towards the corner of the material box 100 that is tilted downwards, so that the corner of the material piece 200 abuts against two adjacent inner walls of the material box 100, thus neatly stacking them in the material box 100.

[0060] Optionally, the support bracket 22 is designed as a flat plate, and the sliding connection bracket 21 includes a plate and a mounting base. One edge of the plate is connected to the mounting base. The mounting base is set on the mounting bracket 1 through a slide rail slider assembly, so that the mounting base and the plate can be guided to move along the length direction of the slide rail slider assembly to switch between the receiving station and the box changing station. The plate is used to support the support bracket 22. The entire mounting bracket 1 can be tilted so that the plate in the sliding connection bracket 21 on the mounting bracket 1 is tilted, and the support bracket 22 at the receiving station is also tilted. When tilted, the plates of the support bracket 22 and the sliding connection bracket 21 are arranged in parallel.

[0061] like Figure 2 and Figure 5 As shown, after the material is collected, the sliding connecting bracket 21 slides to the box changing station. During this process, the second end of the lifting arm 3 slides upward through the lifting ramp 41 to the support plane 42, and the bearing bracket 22 is lifted to a horizontal state, thereby automatically adjusting the material box 100 with the collected material to a horizontal state.

[0062] Optionally, the material box 100 has locking posts around its perimeter. When the material box 100 is arranged horizontally, the locking posts of the material box 100 are also horizontal, so that the material box transporting hook can easily hook onto the locking posts of the material box 100, and ultimately enable the material box transporting hook to smoothly transport the material box 100.

[0063] The cassette in this application embodiment is suitable for receiving silicon wafers, and of course, it is also suitable for receiving other types of wafer products.

[0064] Optionally, a roller 31 is provided at the second end of the lifting arm 3, and the second end of the lifting arm 3 rolls onto the lifting ramp 41 and the supporting plane 42 via the roller 31. By providing the roller 31 at the second end of the lifting arm 3, the friction between the second end of the lifting arm 3 and the lifting ramp 41 and the supporting plane 42 of the lifting block 4 can be reduced, allowing the second end of the lifting arm 3 to smoothly slide upwards onto the supporting plane 42 via the lifting ramp 41, thereby achieving stable lifting and leveling of the support bracket 22 and the material box 100 on it, preventing the material box 100 from shaking and damaging the material sheet during the lifting process.

[0065] like Figure 3 As shown, optionally, the support assembly 23 includes a bolt mounting base 231 and a bolt 232, wherein: the bolt mounting base 231 is fixedly mounted on the sliding connection bracket 21. The bolt 232 is adjustablely screwed onto the bolt mounting base 231, and the load-bearing bracket 22 is supported on the bolt 232. By adjusting the height of the bolt 232, the angle of the load-bearing bracket 22 can be finely adjusted to ensure that after the second end of the lifting arm 3 slides onto the support plane 42, the load-bearing bracket 22 can switch to a horizontal state.

[0066] Optionally, the material box carrying mechanism in this embodiment of the application further includes a first translation drive component 5 disposed on the mounting bracket 1 and connected to the sliding connecting bracket 21 in a transmission manner. The first translation drive component 5 is used to drive the sliding connecting bracket 21 to slide and switch between the receiving station and the box changing station along the first direction.

[0067] The first translation drive assembly 5 can be any existing linear drive module capable of driving the sliding connecting bracket 21 to slide along the first direction, such as a cylinder or a lead screw module.

[0068] like Figures 4 to 6 As shown, optionally, the material box 100 located on the support bracket 22 has two storage cavities arranged side by side along a first direction. A tray 101 is disposed within the material box 100, with the first half of the tray 101 located in one storage cavity A and the second half located in the other storage cavity B. A lifting channel is provided on the sliding connecting bracket 21 and the support bracket 22, and a lifting hole communicating with the lifting channel is provided at the bottom of the material box 100. The material box carrying mechanism also includes a lifting assembly 6 disposed below the sliding connecting bracket 21. The lifting assembly 6 is configured to lift the tray 101 to the high position for receiving the sheet via the lifting channel and the lifting hole. The lifting assembly 6 is also configured to drive the tray 101 downwards during the sheet receiving process.

[0069] Because the material box 100 located on the support bracket 22 has two storage cavities arranged side by side along the first direction, the material receiving mechanism can alternately receive the material pieces onto the first and second halves of the tray 101. During the material receiving process, the lifting assembly 6 drives the tray 101 to descend, ensuring that the descent height of each material piece is within a predetermined range. This descent height is the height from which the material piece falls from the material receiving mechanism onto the tray 101, preventing the material piece from falling too high and causing damage. Ultimately, both storage cavities of the material box 100 can be filled with material pieces. In this way, the amount of material piece received each time can be increased, the frequency of box changing can be reduced, and thus the material receiving efficiency can be improved.

[0070] like Figures 4 to 7 As shown, optionally, the material box carrying mechanism in this embodiment further includes a first air blowing assembly 7 and a second air blowing assembly 8 disposed on the mounting bracket 1. When the sliding connecting bracket 21 is located at the receiving station, the air blowing hole of the first air blowing assembly 7 faces one of the receiving cavities A of the material box 100, and the air blowing hole of the second air blowing assembly 8 faces the other receiving cavity B of the material box 100.

[0071] During the sheet collection process, the first air blowing component 7 and the second air blowing component 8 blow air toward the corresponding collection cavity to straighten the sheet inside the corresponding collection cavity and further improve the neatness of the sheet stacking.

[0072] Optionally, both the first air blowing assembly 7 and the second air blowing assembly 8 are air blowing blocks. The air blowing block has an air chamber connected to a compressed air source, and the side wall of the air blowing block facing the receiving station has an air blowing hole or air blowing slit that communicates with the air chamber.

[0073] To ensure that the first air blowing assembly 7 and the second air blowing assembly 8 only regulate the material sheets in their respective receiving cavities and do not interfere with the material sheets in the other receiving cavity, such as... Figure 7 As shown, optionally, a baffle plate 9 is also provided between the two storage cavities of the material box 100.

[0074] like Figure 7 As shown, optionally, the material box carrying mechanism in this embodiment further includes a guide mechanism 10 located above the material box carrying frame 2. The guide mechanism 10 includes a first baffle 11 and a second baffle 12, wherein: the surface of the first baffle 11 extends along a first direction (e.g., the X direction), and the surface of the second baffle 12 extends along a second direction (e.g., the Y direction), the second direction being perpendicular to the first direction. When the sliding connecting bracket 21 is located at the receiving station, the surface of the first baffle 11 is aligned with the first inner wall 102 of the material box 100, and the surface of the second baffle 12 is aligned with the second inner wall 103 of the material box.

[0075] During the sheet collection process, the first baffle 11 and the second baffle 12 guide the sheet's descent, allowing the sheet to fall more smoothly onto the first and second halves of the pallet 101.

[0076] Optionally, the material box carrying mechanism in this embodiment of the application further includes a second translation drive assembly 13 and a third translation drive assembly 14, wherein: the second translation drive assembly 13 is drivenly connected to the first baffle 11, and the third translation drive assembly 14 is drivenly connected to the second baffle 12.

[0077] When the sliding connecting bracket 21 slides to the receiving station, the second translation drive assembly 13 drives the first baffle 11 to translate along the second direction, thereby adjusting the position of the first baffle 11 to ensure that the surface of the first baffle 11 is aligned with the first inner wall 102 of the material box 100. The third translation drive assembly 14 drives the second baffle 12 to translate along the first direction, thereby adjusting the position of the second baffle 12 to ensure that the surface of the second baffle 12 is aligned with the second inner wall 103 of the material box.

[0078] Both the second translation drive assembly 13 and the third translation drive assembly 14 can adopt various existing linear drive modules such as cylinders.

[0079] like Figure 7As shown, optionally, the material box carrying mechanism in this embodiment further includes a lifting drive assembly 15, which is connected to the first baffle 11 and is used to drive the first baffle 11 to rise and fall. When the first baffle 11 rises to the high position, the lower end of the first baffle 11 is higher than the top of the material box 100. When the first baffle 11 falls to the low position, the lower end of the first baffle 11 is lower than the top of the material box 100.

[0080] When the sliding connecting bracket 21 slides to the receiving station and the material box 100 receives the sheets, the lifting drive assembly 15 drives the first baffle 11 to a low position to guide the sheets. When the material box 100 is full and needs to switch to the changing station to perform a changing operation, the lifting drive assembly 15 drives the first baffle 11 to a high position to avoid the material box 100, so that the material box 100 can be moved away from the receiving station.

[0081] The lifting drive assembly 15 can adopt various existing linear drive modules such as cylinders.

[0082] Based on the same concept, this application also provides a sheet receiving device, which includes a sheet receiving mechanism and a cassette carrying mechanism as described in any of the above embodiments. The sheet receiving mechanism is disposed above the cassette carrying frame and is configured to convey and release sheets into a cassette located on a support bracket. Through the cooperation of the cassette carrying mechanism and the sheet receiving mechanism, the sheet receiving device in this application embodiment can automatically receive sheets into the cassette located on the cassette carrying mechanism, thereby achieving automatic sheet receiving.

[0083] Furthermore, by adjusting the material box carrier, the material box is tilted during the sheet collection process, ensuring that the sheets collected in the material box are neatly stacked inside. Once the material box is full, it is automatically adjusted to a horizontal position, ensuring that the material box handling hooks can smoothly transport the material box.

[0084] The receiving mechanism can use an existing upper adsorption conveyor line, which includes a matching conveyor belt and adsorption blocks, so that the upper adsorption conveyor line has both adsorption and conveying functions, and can adsorb the material sheets onto the conveyor belt for conveying.

[0085] The foregoing has provided a sufficiently detailed and specific description of this application. Those skilled in the art should understand that the descriptions in the embodiments are merely exemplary, and all changes made without departing from the true spirit and scope of this application should fall within the protection scope of this application. The scope of protection claimed in this application is defined by the claims, and not by the above descriptions in the embodiments.
