DETAILED DESCRIPTION
[0029] In order to make the personnel in the technical field better understand the technical scheme in the utility model, the technical scheme in the utility model embodiment will be described clearly and completely below in combination with the drawings in the utility model embodiment. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor should belong to the protection scope of the utility model.
[0030] As Figures 1-3 shown, the utility model discloses an embodiment of a kind of low-temperature laser-induced sintering device for solar cell production, including device body 1, the side wall of device body 1 is equipped with waste cavity 2, the organic exhaust pipe 3 of being installed with waste cavity 2 in device body 1 is located above, waste cavity 2 is connected with the cleaning assembly 4 of organic exhaust pipe 3 matching is clamped in, a pair of inner wall of waste cavity 2 is fixedly connected with fixing assembly 5.Organic exhaust pipe 3 is connected with low-temperature laser-induced sintering device inside one end, the other end is connected with the top end surface of waste cavity 2, the organic mixture generated in sintering process is discharged into cleaning assembly 4 through organic exhaust pipe 3, the top end of cleaning assembly 4 is clamped in organic exhaust pipe 3, fixing assembly 5 is used to stably fix cleaning assembly 4 below organic exhaust pipe 3, when organic matter needs to be cleaned, through the operation of cleaning assembly 4, the dirt and organic mixture adhered to the inner wall of organic exhaust pipe 3 can be cleaned simultaneously.
[0031] As Figures 4-5As shown, the organic discharge pipe 3 includes a double-layer pipe body 301. A central layer 302 is formed on one side wall of the double-layer pipe body 301. Multiple sets of vertical grooves 303 are formed on the inner wall of the double-layer pipe body 301, and the vertical grooves 303 communicate with the central layer 302. The cleaning component 4 includes an extended collection pipe 401 and a first base 404. Multiple sets of connecting blocks 402 that match the vertical grooves 303 are integrally formed on the inner wall of the extended collection pipe 401. Scrapers 403 are integrally formed on the inner wall of the multiple sets of connecting blocks 402. The outer wall of the connecting blocks 402 is attached to the vertical grooves 303. On the inner wall, the inner and outer walls of the extended collection pipe 401 are attached to a pair of inner walls of the central layer 302, and one side wall of the scraper 403 is attached to the inner wall of the double-layer pipe body 301. When cleaning, the staff moves the cleaning component 4 downward, causing the extended collection pipe 401 to slide in the central layer 302, thereby causing the connecting block 402 to slide on the inner wall of the vertical groove 303, and at the same time causing the scraper 403 to scrape on the inner wall of the double-layer pipe body 301, so that the attachments on the surface of the double-layer pipe body 301 fall into the cleaning component 4.
[0032] like Figures 6-7 As shown, a first waste box 405 is integrally formed on the inner wall of the first base 404. The first waste box 405 is integrally formed on the bottom end face of the extended collection pipe 401. A hinge 411 is installed on one side of the bottom end face of the first base 404. A second base 406 is installed on the other side of the hinge 411. A second waste box 407 is integrally formed on the top of the second base 406. A spring lock 410 is installed on the side wall of the first base 404 near the second base 406. The other side of the spring lock 410 is installed on the side wall of the second base 406 near the extended collection pipe 401. The discharged organic mixture is temporarily stored in the first waste box 405 and the second waste box. Inside 407 and the extended collection pipe 401, when the staff cleans the cleaning component 4, first remove the cleaning component 4 away from the waste chamber 2, then lift the handle 409 to move the cleaning component 4 to the organic mixture storage area, open the spring lock 410, rotate the second base 406, and under the action of the hinge 411, rotate the second base 406 to be located below the first base 404, pour out the organic mixture, and then clean the cleaning component 4. After cleaning is completed, rotate the second base 406 to fit against the side of the first base 404, and then close the spring lock 410 so that the second base 406 and the first base 404 are on the same plane.
[0033] like Figure 3 and Figure 8As shown, the waste chamber 2 includes a chamber shell 201. A pair of sliding transverse grooves 202 are formed on each of the inner walls of the chamber shell 201. A pair of T-slots 203 are formed on each of the inner walls of the chamber shell 201 above the sliding transverse grooves 202. A pair of T-blocks 408, matching the sliding transverse grooves 202 and T-slots 203, are integrally formed on the side walls of both ends of the first base 404 and the second base 406. Handles 409 are welded to the top surfaces of both ends of the first base 404 and the second base 406. The upper and lower surfaces of the T-blocks 408 slide within the sliding transverse grooves 202. The sidewall of the T-block 408 slides and adheres to the inner wall of the T-groove 203. When the cleaning component 4 is installed after cleaning, the cleaning component 4 is first placed in the chamber housing 201, so that the T-block 408 slides in the sliding transverse groove 202. When the T-block 408 slides to the bottom of the T-groove 203, the worker drives the cleaning component 4 to move upward, so that the T-block 408 slides in the T-groove 203. At this time, the extended collection pipe 401 slides in the central layer 302. When the T-block 408 slides to the top inner wall of the T-groove 203, it stops.
[0034] Furthermore, the cleaning component 4 is only used to support the organic mixture generated during the sintering process, and can be made of lightweight metals such as aluminum and magnesium, which also have high corrosion resistance.
[0035] like Figure 2 As shown, the fixing component 5 includes a fixing block 501, which is welded to a pair of inner walls of the chamber shell 201. Threaded rods 502 are welded to the two side walls of the fixing block 501. Threaded sleeves 503 are threadedly connected to the threaded rods 502. Hooks 504 are integrally formed at the bottom end of the threaded sleeves 503. A pair of hooks 504 are provided and are respectively engaged with the outer walls of a pair of handles 409. When the organic mixture is collected, the fixing component 5 makes the cleaning component 4 stably fixed in the waste chamber 2.
[0036] When using the low-temperature laser-induced sintering device, the organic mixture is transported through the organic discharge pipe 3 to the cleaning component 4 located in the second waste box 407, the first waste box 405, and the extended collection pipe 401. The operator needs to clean the organic discharge pipe 3 and the cleaning component 4 regularly. During cleaning, firstly, rotate a pair of hooks 504 located in the waste chamber 2 so that the hooks 504 are rotated to the side away from the handle 409. Then, the cleaning component 4 is driven to slide down along the T-slot 203. At this time, the extended collection pipe 401 located in the organic discharge pipe 3 drives the scraper 403 to scrape down, thereby cleaning the inner wall of the organic discharge pipe 3. Then, the cleaning component 4 is driven to slide along the sliding transverse groove 202 to the outside of the device. Then, the cleaning component 4 is cleaned. This device achieves cleaning of the organic discharge pipe at the same time as cleaning the organic discharge collection component, avoiding dirt from adhering to the organic discharge pipe after long-term use and causing blockage, which affects the sintering efficiency.
