Description

Technical Field

[0001] The invention relates to a conveying mechanism. Background Art

[0002] Currently, photovoltaic diffusion equipment first moves silicon wafers and quartz boats from the feed and discharge modules to the transfer platform for placement. When the process furnace needs to be processed, the vertical transport module and the horizontal transport module work together to move the silicon wafers and quartz boats onto the paddles. The module that transports the quartz boat carrying the silicon wafers horizontally to the paddles uses a dual-module drive mechanism. The dual-module structure consists of one upper and one lower module, with one drive motor each, and the equipment occupies a large area.

[0003] With the substantial increase in silicon wafer size and production capacity, the size of the module also needs to be increased accordingly to meet the increased weight and stroke, and the size of the module is standard. The selection of a module that can withstand the load may actually far exceed the actual load capacity, which results in a waste of design. Specifically, the existing standard linear modules have a span, which may be 100-200-300, and the module's external dimensions are fixed. For example, the sizes of 70, 90, 120, and 220 have spans. Assuming that the size of 90 can meet the load, if the size of the silicon wafer increases, a module of size 150 can be used through calculation, but if there is no module of size 150, only a module of size 220 can be selected, which will waste the load and design, increase the floor space of the equipment, and increase the cost.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] like Figures 1 to 4 The conveying mechanism shown is used to convey products, and the products may be quartz boats carrying silicon wafers. The conveying mechanism comprises a driving component 1, a transmission assembly, a first displacement assembly, a second displacement assembly, a first connection assembly, and a second connection assembly.

[0029] The first conveyor belt 2 and the second conveyor belt 3 are located in the same horizontal plane and are arranged in parallel, that is, the extension directions of the first conveyor belt 2 and the second conveyor belt 3 are parallel, and the driving component 1 is used to drive the first conveyor belt 2 and drive the second conveyor belt 3 to run synchronously. The first conveyor belt 2 and the second conveyor belt 3 are synchronous belts and can run simultaneously.

[0030] The transmission assembly also includes a driving wheel 4, a first driven wheel 20, a second driven wheel 5, and a third driven wheel 21. The first conveyor belt 2 is wound between the driving wheel 4, the first driven wheel 20, and the second driven wheel 5. The second conveyor belt 3 is wound between the second driven wheel 5 and the third driven wheel 21. The driving component 1 is connected to the driving wheel 4 to drive the driving wheel 4 to rotate to drive the first conveyor belt 2 to transmit. The driving component 1 is preferably a motor, and the driving shaft of the motor is connected to the driving wheel 4.

[0031] One end of the first conveyor belt 2 and the second conveyor belt 3 are both wound around the same second driven wheel 5, the other end of the first conveyor belt 2 is wound around the second driven wheel 5, and the other end of the second conveyor belt 3 is wound around the third driven wheel 21. The other end of the first conveyor belt 2 and the other end of the second conveyor belt 3 are not wound around the same driven wheel. The length of the first conveyor belt 2 is greater than that of the second conveyor belt 3, and they are staggered and fixed to facilitate tensioning the conveyor belts.

[0032] The first driven wheel 20 and the second driven wheel 5 are located in the same horizontal plane, and the setting position of the driving wheel 4 is higher than the setting positions of the first driven wheel 20 and the second driven wheel 5, so as to facilitate the adjustment of the tightness of the first conveyor belt 2.

[0033] The transmission assembly further includes one or more pressure rollers 13 , which are used to press the first conveyor belt 2 to ensure stable conveyance of the first conveyor belt 2 . The driving wheel 4 is disposed at a position higher than that of the pressure rollers 13 .

[0034] The first connection assembly is connected to the first displacement assembly and is used to support the product, and the second connection assembly is connected to the second displacement assembly. The first displacement assembly and the second displacement assembly are arranged on the side of the second conveyor belt 3 away from the first conveyor belt 2, and the extension direction of the first displacement assembly and the second displacement assembly is parallel to the extension direction of the first conveyor belt 2 and the second conveyor belt 3.

[0035] The first displacement assembly is located above the second displacement assembly, the first displacement assembly is connected to the second conveyor belt 3 via the first connecting assembly, the second displacement assembly is connected to the second conveyor belt 3 via the second connecting assembly, the second conveyor belt 3 is used to drive the first displacement assembly to move the product, and drive the second displacement assembly to move in the horizontal direction; the moving direction of the first displacement assembly is opposite to the moving direction of the second displacement assembly.

[0036] The driving component 1 (with the motor being the best) drives the synchronous belt, the first conveyor belt 2 and the second conveyor belt 3 to move simultaneously. The first conveyor belt 2 and the second conveyor belt 3 move the same stroke at the same time. The first displacement component is connected to the second conveyor belt 3 through the first connecting component. The stroke of the first connecting component is the sum of the strokes of the first conveyor belt 2 and the second conveyor belt 3, that is, when the motor rotates one circle, the first connecting component passes through the first conveyor belt 2 and the second conveyor belt 3, which is equivalent to the distance of two circles of the motor rotation. The conveying mechanism has doubled the stroke compared with the ordinary module, reducing the equipment size and design flexibility, and improving efficiency. By driving two conveyor belts and driving the movement of the first displacement component and the second displacement component through a driving component 1, power is saved and double the stroke is achieved (the conveying mechanism can achieve a larger stroke under a structural size similar to that of the existing module, generally twice the stroke of the traditional structure). The circumference of the existing conveying mechanism motor driving wheel rotating one circle is the movement distance of the end actuator, and the movement distance of the end actuator of the conveying mechanism of the present application is twice the circumference of the motor driving force rotating one circle.

[0037] The structures of the first displacement assembly and the second displacement assembly are as follows: the first displacement assembly includes a first guide rail 6 and a first slider 7, the first slider 7 is arranged on the first guide rail 6 and can move along the first guide rail 6; the second displacement assembly includes a second guide rail 8 and a second slider 9, the second guide rail 8 is located below the first guide rail 6, the second slider 9 is arranged on the second guide rail 8 and can move along the second guide rail 8, and the extension direction of the first guide rail 6 and the second guide rail 8 is parallel to the extension direction of the first conveyor belt 2 and the second conveyor belt 3.

[0038] The first connecting component is connected to the second conveyor belt 3 and the first slider 7 and is used to support the product. The second connecting component is used to connect the second conveyor belt 3 and the second slider 9.

[0039] The second conveyor belt 3 is used to drive the first slider 7 to move along the first guide rail 6 to drive the first connecting assembly to move, and simultaneously drive the second slider 9 to move along the second guide rail 8. The moving direction of the first slider 7 is opposite to that of the second slider 9.

[0040] The first connecting component includes a first connecting member 10 and a second connecting member 11. The first connecting member 10 is connected to the second conveyor belt 3. The second connecting member 11 is connected to the first connecting member 10 and the first slider 7. The second connecting member 11 is used to place products. The second connecting component includes a third connecting member 12. The third connecting member 12 is connected to the second conveyor belt 3 and the second slider 9.

[0041] Through the coordination of the first conveyor belt 2, the second conveyor belt 3, the first displacement assembly and the second displacement assembly, the size of the equipment is reduced and the overall structure is more compact; the design is more flexible: for example, the first slider 7 and the second slider 9 are provided in plurality. When the load of the product to be carried increases (the weight increases), there is no need to replace the entire conveying mechanism. It is only necessary to appropriately increase the number of the first slider 7 and the second slider 9 to improve the carrying capacity, facilitate the transportation of silicon wafers of different sizes, greatly save costs, and improve production efficiency.

[0042] The conveying mechanism further includes a fixing plate, which is disposed between the first guide rail 6 and the second guide rail 8 and is used to fix the first guide rail 6 and the second guide rail 8 .

[0043] The conveying mechanism also includes a support assembly for fixing the transmission assembly and the displacement assembly. The support assembly includes a first support plate, a second support plate, a third support plate, and a base connected in sequence. The first support plate and the third support plate are arranged opposite to each other, and the two ends of the fixed plate are fixedly connected to the first support plate and the third support plate respectively. The base is connected under the second support plate and the third support plate. The base is used to support the second slider 9. The first support plate, the second support plate, the third support plate, and the base enclose a space to accommodate the transmission assembly and the displacement assembly. The first driven wheel 20, the second driven wheel 5, and the third driven wheel 21 are arranged between the second support plate and the fixed plate.

[0044] The support assembly also includes a fixed seat 19, which is arranged on the side of the second support plate away from the first conveyor belt 2. The fixed seat 19 is fixedly connected to the second support plate. A plurality of mounting holes are opened on the fixed seat 19, one mounting hole is used for passing the driving shaft of the power supply motor, and one mounting hole is used for installing the rotating shaft of the pressure roller 13.

[0045] The conveying mechanism of the present application can conveniently and flexibly modify the size and quantity of the first displacement component and the second displacement component according to the actual calculated load conditions, can flexibly accommodate larger or smaller loads, avoid the design waste of large load span of standardized modules, and better achieve economic benefits. Specifically: when the size of the silicon wafer increases significantly, first calculate the load required by the entire conveying mechanism and then design the size of the conveying mechanism, and freely select the linear guide rail combination: for example, when the load (weight increase) of the product to be carried remains unchanged while the stroke remains unchanged, there is no need to replace the entire conveying mechanism, and only the number of the first slider 7 and the second slider 9 needs to be appropriately increased to improve the load-bearing capacity; for example, when the load (weight increase) of the product to be carried remains unchanged while the stroke increases, it is necessary to replace the first conveyor belt 2, the second conveyor belt 3, the first guide rail 6, the second guide rail 8, the second support plate, the fixed plate, etc., without replacing the driving wheel 4, the driven wheel, the fixing seat 19, the base, etc., that is, there is no need to replace all the conveying mechanisms, which can save costs.

[0046] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
