Description

Technical Field

[0001] The present invention belongs to the technical field of automated conveying equipment, and more particularly, relates to an adaptive and adjustable transmission conveying system. Background Art

[0002] With the increasing depletion of fossil energy, solar cells have been developed in the long term due to their clean and renewable advantages. Among many photovoltaic cells, such as TOPCon (tunneling oxide passivation contact) cells, HJT (heterojunction) cells and XBC (interdigitated back contact) cells, vacuum coating technology is a key process for the preparation of solar cells. Hot Filament Chemical Vapor Deposition (HoFCVD) equipment, as an emerging large-scale coating equipment, has the advantages of high film formation rate, good coating uniformity, and no ion damage. It has been applied to the field of crystalline silicon heterojunction solar cell coating. Currently, HoFCVD vacuum coating equipment is mainly vertical. The carrier board carrying the silicon wafer needs to be continuously transported to each chamber for different coating processes. Since each chamber is independently closed, the existing method of transporting the carrier board mainly adopts two sets of gear conveying devices (one gear is equipped with a motor and a clutch) in each chamber to achieve transportation.

[0003] However, in the current rack-and-pinion system for conveying carriers, when the rack-and-pinion is engaged, the rear gear drive unit must release the clutch, while the front gear drive unit closes the clutch to convey the carrier.

[0052] A floating tensioner 13 is fixedly mounted on the second fixing seat 11 and connected to the upper side of the synchronous belt 3;

[0053] Two springs 12 are respectively installed at both ends of the bottom of the second fixed seat 11.

[0054] The fixed tensioning wheel 14 is fixedly mounted on the first fixing seat 10 at the lower end of the guide column 9 and is connected to the lower side of the synchronous belt 3.

[0056] In the above embodiments of the present invention, Figure 1 and 3 As shown, the clutch 1 is closed when the carrier plate 7 moves to the chamber and is disconnected when the carrier plate 7 leaves the chamber; the adaptive tensioning mechanism 4 releases the engagement error when the carrier plate 7 leaves the chamber, and at this time, the rotation angle of the second transmission wheel 8 is the sum of the rotation angle of the first transmission wheel 5 and the rotation angle caused by the release of the engagement error.

[0057] In the above embodiments of the present invention, Figure 1 and 3 As shown, the arrival signal detection of the carrier 7 is achieved by setting two sensors at the end of the carrier conveying path, and no sensor is required in the middle of the carrier conveying path. Preferably, the two sensors are a deceleration sensor and an arrival sensor in sequence.

Of course, in other optional embodiments, the first transmission wheel 5 and the second transmission wheel 8 can be other similar structures, and the transmission bar 6 can also be other similar structures.

[0060] In the above embodiments of the present invention, Figure 1 and 3 As shown, the adaptive adjustable transmission conveying system is suitable for single chamber drive, such as Figure 1 As shown, or the adaptive adjustable transmission conveying system is suitable for multi-chamber combination drive, such as Figure 3 shown.

[0061] The above technical solution of the present invention is described in detail below through specific embodiments.

[0062] Refer again Figure 1 In one embodiment of the present invention, an adaptive adjustable transmission conveying system is provided. The adaptive adjustable transmission conveying system is a structural schematic diagram in a single chamber state. The system includes: a clutch 1, a power device 2, a synchronous belt 3, an adaptive tensioning mechanism 4, a first transmission wheel 5 and a second transmission wheel 8 (both are gears in this embodiment), a transmission bar 6 (a rack in this embodiment) and a carrier plate 7. Among them, the rack (transmission bar 6) is arranged along the movement direction of the carrier plate 7, and the carrier plate 7 is placed on the rack; the first gear (first transmission wheel 5) is separated from the second gear (second transmission wheel 8) and is connected by a synchronous belt 3 and a synchronous wheel (not shown) to achieve synchronous movement. The first gear is connected to the power device 2, and only the clutch 1 is provided between the first gear and the power device 2. The power device 2 provides power, the clutch is closed, the first gear rotates and engages with the rack, driving the carrier plate 7 to move along the direction of the rack; the adaptive tensioning mechanism 4 is positioned between the first gear (first transmission wheel 5) and the second gear (second transmission wheel 8) and is connected to the synchronous belt 3. The adaptive tensioning mechanism 4 adjusts the tightness of the synchronous belt 3 to automatically adjust the meshing error generated when the first gear and the rack are meshed, thereby achieving smooth movement of the rack.

[0063] In this embodiment, the carrier plate 7 is moved from the upper chamber along the Figure 1When the gear moves in the direction of motion shown in the figure and enters this chamber, the clutch 1 is closed, driving the first gear to rotate; when the first gear is engaged with the rack, the adaptive tensioning mechanism 4 is used to adjust the tightness of the synchronous belt 3, thereby automatically adjusting the meshing error caused by the meshing of the first gear and the rack when driving the rotation of the first gear, thereby achieving smooth movement of the rack.

[0064] In this embodiment, when the carrier plate 7 is detached from this chamber, the adaptive tensioning mechanism 4 releases the meshing error generated during meshing. At this time, the rotation angle of the second gear (the second transmission wheel 8, i.e., the driven end gear) is the rotation angle θ1 of the first gear (the first transmission wheel 5, the power end gear) + the rotation angle θ2 generated by releasing the meshing error.

[0065] Therefore, when the rack (transmission bar 6) engages from the active end to the driven end and from a single chamber to the next chamber, the principle and process are as described above.

[0066] Therefore, the process of smooth operation of the above conveying system is as follows:

[0067] (1) The carrier enters the chamber

[0068] The carrier plate 7 carries the silicon wafer from the upper chamber along Figure 1 Move in the direction of motion shown, gradually approaching this chamber.

[0069] When the carrier plate 7 is about to enter the chamber, the clutch 1 is closed, so that the power device 2 forms a linkage relationship with the first gear (first transmission wheel 5). The power device 2 (preferably a motor) starts working to provide power for the rotation of the first gear.

[0070] (2) Engagement and initial driving stage

[0071] The first gear starts to rotate under the drive of the power device 2 , and as the carrier plate 7 moves further in, the first gear and the rack gradually enter into a meshing state.

[0072] During the meshing of the first gear and the rack, the adaptive tensioning mechanism 4 comes into play. The synchronous belt 3 drives the second gear (second transmission wheel 8) to rotate. However, since the carrier plate 7 has not yet fully entered the stable conveying phase, the second gear mainly rotates to keep the synchronous belt 3 in a taut state.

[0073] (3) Stable conveying stage

[0074] When the carrier plate 7 completely enters the chamber, the first gear and the rack are tightly meshed, and the power device 2 continuously drives the first gear to rotate, thereby driving the carrier plate 7 to move smoothly along the direction of the rack through the meshing relationship.

[0075] The adaptive tensioning mechanism 4 continuously monitors and adjusts the tension of the timing belt 3. If a meshing error occurs, causing a change in the meshing state, such as a slight displacement deviation, the adaptive tensioning mechanism 4 adjusts the tension of the timing belt 3, thereby automatically correcting the meshing error and ensuring that the movement speed and stability of the carrier plate 7 are not affected.

[0076] (4) Carrier board separation stage

[0077] When the carrier plate 7 completes the process in the chamber and needs to leave the chamber, the clutch 1 is disconnected and the power device 2 stops driving the first gear.

[0078] The adaptive tensioning mechanism 4 begins to release the previously accumulated meshing error. During this process, the adaptive tensioning mechanism 4 causes the second gear to rotate by a certain angle, which is the sum of the rotation angle θ1 of the first gear at the power end and the rotation angle θ2 generated by releasing the meshing error. This ensures that the carrier plate 7 can be smoothly released from the chamber and smoothly enter the next conveying stage.

[0079] During the entire conveying process of the carrier 7, the adaptive tensioning mechanism 4 always makes real-time adjustments to the tensioning state of the synchronous belt 3 and the meshing condition of the gear and rack, ensuring that the carrier 7 can maintain smooth operation in all links of entering, conveying and leaving the chamber, improving the conveying accuracy and reliability, reducing problems such as carrier jitter and jamming caused by meshing errors, and ensuring the efficient and stable operation of the entire photovoltaic automation production line.

[0080] In the above embodiment of the present invention, the adaptive tensioning mechanism 4 is a key component to achieve the purpose. Figure 1 and 2 As shown, an embodiment of the present invention provides a schematic diagram of the specific structure of the adaptive tensioning mechanism 4. In this embodiment, the adaptive tensioning mechanism 4 includes two parallel guide posts 9, two first fixed seats 10, a second fixed seat 11, two springs 12, a floating tensioning pulley 13, and a fixed tensioning pulley 14. The upper and lower parts of the two guide pillars 9 are respectively fixedly mounted on the corresponding first fixed seats 10; the second fixed seat 11 is movably mounted on the two guide pillars 9, and a guide sleeve (not shown) is provided in the second fixed seat 11. The second fixed seat 11 cooperates with the guide pillar 9 through the guide sleeve and can move along the guide pillar 9; the floating tensioner 13 is fixedly mounted on the second fixed seat 11 and connected to the upper side of the synchronous belt 3; two springs 12 are respectively mounted at both ends of the bottom of the second fixed seat 11. The springs 12 make the first gear (first transmission wheel 5) and the second gear (second transmission wheel 8) in a relative position, and allow the floating tensioner 13 to move to absorb the meshing error when the meshing error occurs; the fixed tensioner 14 is fixedly mounted on the first fixed seat 10 at the lower part of the guide pillar 9 and connected to the lower side of the synchronous belt 3.

[0081] In this adaptive tensioning mechanism, a guide post 9 is mounted on a first fixed seat 10, guiding the movement of a floating tensioner 13. The floating tensioner 13 is fixed to a second fixed seat 11, which contains a guide sleeve that facilitates smoother movement of the floating tensioner 13, facilitating the mechanism's responsiveness and functionality. Spring 12 is the key to achieving adaptability. It generates initial tension to align the two gears (the first transmission wheel 5 and the second transmission wheel 8) relative to each other. When meshing errors cause the gears to rotate relative to each other, the movement of the floating tensioner 13 absorbs the meshing errors, thereby ensuring a constant rack speed. In addition to absorbing meshing errors, the floating tensioner 13 also tensions the timing belt 3, ensuring smooth rack movement. A fixed tensioner 14 tensions the loose end of the timing belt 3. Tooth skipping is common when the timing belt 3 is too long and untensioned. Increasing tension enhances the stability of the system.

[0082] When the above-mentioned adaptive tensioning mechanism is in operation, the process is as follows:

[0083] (1) Initial state

[0084] Guide post 9 is mounted within first fixed seat 10, while floating tensioner 13 is fixed to second fixed seat 11. A guide sleeve within second fixed seat 11 engages with guide post 9. Two springs 12 are mounted on second fixed seat 11. Floating tensioner 13 and fixed tensioner 14 are connected to timing belt 3, respectively. At this point, the two springs 12 are in their initial tension, providing initial tension for the entire system. This positions the first gear (first transmission wheel 5) and the second gear (second transmission wheel 8) in the appropriate relative positions, ensuring a certain initial tension on timing belt 3 and enabling the two gears to move synchronously.

[0085] (2) The carrier enters the chamber

[0086] When the carrier plate 7 enters the current chamber from the previous chamber, the clutch 1 is closed, the power device 2 starts to drive the first gear to rotate, and the first gear and the rack gradually enter into a meshing state.

[0087] As the first gear rotates, the second gear also starts to rotate through the transmission of the synchronous belt 3 and the synchronous wheel. However, since the carrier plate 7 has not yet fully entered the stable conveying stage, the second gear mainly plays the role of following the rotation to ensure the tension of the synchronous belt.

[0088] (3) Meshing error adjustment stage

[0089] If a meshing error occurs during the meshing of the first gear and the rack, such as a slight displacement deviation, causing the tension of the synchronous belt 3 to change, the floating tensioner 13, driven by the synchronous belt 3, moves along the guide post 9 via the second fixed seat 11, adjusting the tension of the synchronous belt 3 by compressing or stretching the spring 12. Specifically, if the tension of the synchronous belt 3 increases, the floating tensioner 13 moves downward along the guide post 9 under the action of the tension, compressing the spring 12. Conversely, if the tension of the synchronous belt 3 decreases, the spring 12 pulls the second fixed seat 11 and the floating tensioner 13 upward, stretching the synchronous belt 3. This automatically corrects the meshing error and ensures that the movement speed and stability of the carrier plate 7 are not affected.

[0090] (4) Smooth conveying stage

[0091] Once carrier plate 7 has fully entered this chamber, the first gear and rack remain tightly meshed, and power unit 2 continues to rotate the first gear. This meshing relationship drives carrier plate 7 to move smoothly along the rack. Adaptive tensioning mechanism 4 continuously monitors and adjusts the tension of timing belt 3, ensuring it remains appropriately tensioned. This allows the first and second gears to maintain stable, synchronized motion, ensuring smooth transport of the carrier plate.

[0092] (5) Carrier separation stage

[0093] When the carrier plate 7 completes the process in the chamber and needs to leave the chamber, the clutch 1 is disconnected and the power device 2 stops driving the first gear.

[0094] Adaptive tensioning mechanism 4 begins to release the previously accumulated meshing error. The floating tensioner 13 rebounds under the force of spring 12, driving the timing belt 3 to adjust its position. This causes the second gear to rotate a certain angle during this process. This angle is the sum of the rotation angle of the first gear at the power end and the rotation angle caused by releasing the meshing error. This ensures that the carrier can smoothly disengage from the chamber and smoothly enter the next conveying stage.

[0095] Therefore, during the entire carrier conveying process, the adaptive tensioning mechanism adjusts the tensioning state of the synchronous belt 3 and the meshing condition of the gear and rack in real time through the coordinated action of the spring 12, the floating tensioning wheel 13, the guide column 9 and other components, ensuring that the carrier 7 can maintain smooth operation in all links of entering, conveying and leaving the chamber, improving the conveying accuracy and reliability, reducing the problems of carrier jitter, jamming and other problems caused by meshing errors, and ensuring the efficient and stable operation of the entire photovoltaic automation production line.

[0096] Furthermore, in the embodiment of the present invention, the arrival signal of the carrier 7 can be obtained by only placing two sensors at the end of the conveyor path: a deceleration sensor and an arrival sensor. No intermediate sensors are required. As a result, the present invention uses a small number of sensors and simplifies control.

[0097] Alternatively, the above-mentioned conveying system can be applied to multi-chamber combination drive in addition to the single-chamber drive as described above, such as Figure 3 As shown, the above-mentioned conveying system is arranged in sequence according to the number of chambers, each of which is independent and not limited in number, for example, Figure 3 As shown in FIG, after the carrier 7 is transported by the above-mentioned conveying system in the first chamber, the carrier 7 enters the next chamber and continues to be transported by the above-mentioned conveying system. After completion, the carrier 7 continues to enter the next chamber. The carrier 7 is continuously transported by the above-mentioned conveying system until the carrier 7 is transported to the desired nth chamber. In this embodiment, each chamber is independently equipped with a set of the above-mentioned conveying systems, which can always achieve smooth operation, efficient transmission, and stable and reliable operation of the carrier.

[0098] Of course, the above embodiments of the present invention are merely examples of the present invention, and any other similar structures are also within the scope of the present invention. In addition, the meshing of the gear and rack used in the above embodiments of the present invention can also be replaced by the meshing of a sprocket and a chain, or other similar structures.

[0099] In addition, the present invention is used in photovoltaic automation production line equipment, but the present invention is not limited to use in photovoltaic automation production equipment, nor is it limited to use in new energy industry equipment, and is not limited to use in other automation equipment.

[0100] It can be seen that the self-adaptive adjustable transmission and conveying system provided by the present invention can achieve accurate positioning of carrier boards and reliable transmission. The conveying system of the present invention can achieve smooth operation, efficient transmission, and stable and reliable transmission of carrier boards.
