Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of automated loading and unloading equipment for tubular PECVD, and particularly relates to a device for semi-automatic cleaning of the loading and unloading belts of a PECVD machine. Background Technology
[0002] In the current solar cell production process, the conveyor belt is a crucial point of direct contact. The cleanliness of the conveyor belt has a significant impact on the EL yield of the finished cells. Dust contamination can occur during the tubular PECVD production of solar cells. Some of the dust on the cells will remain on the conveyor belt. If the conveyor belt is not cleaned in time, it will contaminate normal cells and cause batch defects. In addition, replacing a new conveyor belt without wiping it will also cause batch defects because the cleanliness of the new conveyor belt is poor. Currently, the production line solves these problems by manually wiping it with a clean cloth. This not only requires a long downtime, which reduces production capacity, but also increases labor costs, all of which lead to losses in company profits. Utility Model Content

[0027] Example 1
[0028] like Figure 1-7 As shown, a semi-automatic device for cleaning the loading and unloading belts of a PECVD machine includes a slide rail assembly, a storage assembly slidably connected to the upper end of the slide rail assembly, a cleaning assembly rotatably connected inside the storage assembly via a rotating shaft 7, a telescopic spring rod 6 provided between the storage assembly and the middle of the cleaning assembly, and the front end of the cleaning assembly abutting against the outside of the belt 1.
[0029] The working principle of the above technical solution is as follows: When it is necessary to clean the belt 1, the cleaning component is pulled outward. The cleaning component rotates with the storage component through the rotating shaft 7. The front end of the cleaning component rotates out from the storage component. Under the elastic force of the telescopic spring rod 6, the front end of the cleaning component abuts against the outside of the belt 1. The inside of the belt 1 is supported by the transmission shaft 2. The transmission shaft 2 rotates, driving the belt 1 to rotate. The cleaning component cleans the outer surface of the belt 1, sweeping away the dust adhering to the belt 1, keeping the belt 1 clean. There is no need to stop the machine for manual cleaning, which increases production efficiency and reduces labor costs.
[0030] When belt 1 does not need to be cleaned, the cleaning component can be stored in the storage component, saving space.
[0031] Example 2
[0032] like Figure 1-7 As shown, the slide rail assembly includes a slide rail base 4, and a slide rail inner groove 14 is provided in the slide rail base 4, and the storage component slides in the slide rail inner groove 14.
[0033] Both ends of the slide rail base 4 are provided with control components 3, and the control components 3 are connected to the storage components.
[0034] The working principle of the above technical solution is as follows: the control component 3 can be a cylinder, which is fixed at both ends of the slide rail base 4. The output end of the cylinder is connected to the storage component. The cylinder controls the storage component to slide in the inner groove 14 of the slide rail, which drives the cleaning component in the storage component to move to a distance and angle that matches the end of the belt 1. Through the above adjustment, it can be adapted to the cleaning of belts 1 of different specifications and belts 1 of different setting heights.
[0035] Example 3
[0036] like Figure 1-7 As shown, the storage component includes a storage box 5, a sliding rod 15 at the bottom of the storage box 5, the sliding rod 15 slides in the inner groove 14 of the slide rail, the control component 3 is connected to the storage box 5, the storage box 5 is rotatably connected to the cleaning component through a rotating shaft 7, and a telescopic spring rod 6 is provided between the middle of the storage box 5 and the cleaning component.
[0037] The working principle of the above technical solution is as follows: Under the elastic force of the telescopic spring rod 6, the front end of the cleaning component can always keep in close contact with the belt 1, thereby increasing the cleaning force of the cleaning component on the belt 1 and ensuring the cleanliness of the belt 1.
[0038] Example 4
[0039] like Figure 1-7 As shown, the storage box 5 is equipped with a magnetic strip 11, which magnetically attaches to the cleaning components.
[0040] The working principle of the above technical solution is as follows: When cleaning the belt 1 is not required, the cleaning component lies flat in the storage box 5, and the magnetic strip 11 is magnetically attached to the cleaning component. The attraction force between the magnetic strip 11 and the cleaning component is greater than the elastic force of the retractable spring rod 6. When cleaning the belt 1 is required, the cleaning component is pulled outward, the magnetic strip 11 separates from the cleaning component, and the cleaning component loses the magnetic force of the magnetic strip 11. Under the elastic force of the retractable spring rod 6, the front end of the cleaning component presses against the belt 1 to clean the belt 1. When it is necessary to store the belt 1, the cleaning component is pressed into the storage box 5, the retractable spring rod 6 is compressed, and the cleaning component is magnetically attached to the magnetic strip 11 in the storage box 5 to complete the storage of the cleaning component. The removal and storage of the cleaning component are convenient and quick.
[0041] Example 5
[0042] like Figure 1-7 As shown, the upper end of the storage box 5 is connected to the top cover 12 via a hinge 13;
[0043] The working principle of the above technical solution is as follows: After the cleaning components are stored in the storage box 5, the top cover 12 is locked onto the storage box 5 by rotation, which has the function of preventing dust.
[0044] Example 6
[0045] like Figure 1-7 As shown, the cleaning assembly includes a cleaning crossbar 8, which is rotatably connected to the storage box 5 via a pivot 7. A telescopic spring rod 6 is provided between the cleaning crossbar 8 and the storage box 5, and the cleaning crossbar 8 is magnetically attached to the magnetic strip 11.
[0046] The front end of the cleaning crossbar 8 is connected to the circular brush head 10 via a detachable component 9, and the bristles of the circular brush head 10 rest against the outside of the belt 1.
[0047] The working principle of the above technical solution is as follows: The cleaning bar 8 is made of magnetic metal. When the belt 1 needs to be cleaned, the cleaning bar 8 is pulled outward, and the cleaning bar 8 is released from the magnetic attraction of the magnetic strip 11. The circular brush head 10 at the front end of the cleaning bar 8 rotates out from the storage box 5. Under the elastic force of the telescopic spring rod 6, the circular brush head 10 presses against the outside of the belt 1. As the belt 1 rotates, the circular brush head 10 cleans the belt 1. The circular brush head 10 can be fixed and separated from the cleaning bar 8 through the detachable component 9, which facilitates the replacement of the circular brush head 10. When the belt 1 does not need to be cleaned, the cleaning bar 8 is pressed into the storage box 5. The telescopic spring rod 6 is compressed, and the cleaning bar 8 contacts and magnetically attracts the magnetic strip 11. The top cover 12 is locked onto the storage box 5 by rotation, which has a dustproof function.
[0048] Example 7
[0049] like Figure 1-7As shown, the detachable component includes a first connecting block 901, which is fixedly connected to the circular brush head 10. The first connecting block 901 is fixedly connected to one end of the elastic rod 902. A right-angle hook 903 is provided on the lower side of the other end of the elastic rod 902, and an oblique hook 904 is provided on the upper side of the other end of the elastic rod 902. The first connecting block 901 is inserted into the second connecting block 905, which is fixedly connected to the cleaning crossbar 8. A snap-fit block 906 is provided inside the second connecting block 905, and the right-angle hook 903 snaps onto the snap-fit block 906.
[0050] The connecting block 905 is slidably connected to the push block 907. The lower end of the push block 907 is fixed with a slider 908. The slider 908 slides between the connecting block 905 and the snap-fit block 906. The inclined plate 909 on the slider 908 is slidably connected to the angled hook 904. The pressing block 910 on the slider 908 is inserted between the elastic rod 902 and the connecting block 905.
[0051] The working principle of the above technical solution is as follows: Pushing the push block 907 towards the side of the cleaning crossbar 8 causes the slider 908 to move towards the side of the cleaning crossbar 8, causing the squeezing block 910 to move out from between the elastic rod 902 and the connecting block 905. The inclined plate 909 slides with the angled hook 904 and squeezes the angled hook 904 to move outward, causing the front end of the elastic rod 902 to open outward, causing the right angle hook 903 to move outward and separate from the locking block 906. Pulling the circular brush head 10 outward completes the separation between the connecting block 901 and the connecting block 905, and completes the separation between the circular brush head 10 and the cleaning crossbar 8. The disassembly of the circular brush head 10 and the cleaning crossbar 8 is convenient and quick.
[0052] Connecting block 1 901 and connecting block 2 905 are inserted together, and right-angle hook 903 is engaged with locking block 906. Pushing push block 907 forward moves slider 908 forward, causing squeezing block 910 to be inserted between elastic rod 902 and connecting block 2 905, thus completing the installation and fixation between circular brush head 10 and cleaning crossbar 8. The squeezing action of squeezing block 910 prevents elastic rod 902 from bending, further ensuring the firmness of the engagement between right-angle hook 903 and locking block 906, and enhancing the stability of the installation between circular brush head 10 and cleaning crossbar 8.
