[0038] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0039] Please refer to Figure 1The embodiment of the present application provides a pipeline 100, which comprises a rack 10, a transmission assembly 20, a spraying assembly 30 and a scraper assembly 40, is used for transmitting workpieces and cleaning foreign matters adhered on the transmission assembly 20, and improves transmission quality. Exemplarily, the workpieces can be mobile phone middle plates, mobile phone shells and the like, and the foreign matters can be solidified polishing wax, metal scraps and the like.

[0040] Please refer to Figure 1 The transmission assembly 20 is arranged on the rack 10 and is used for transmitting workpieces. The spraying assembly 30 is arranged above the transmission assembly 20 and is connected with the rack 10, and the spraying assembly 30 is used for spraying liquid towards the transmission assembly 20, so that the liquid softens the foreign matters adhered on the transmission assembly 20. The scraper assembly 40 is arranged below the transmission assembly 20 and is connected with the rack 10, the scraper assembly 40 abuts against the surface of the transmission assembly 20, and the scraper assembly 40 is used for scraping the softened foreign matters from the transmission assembly 20. Exemplarily, the transmission assembly 20 can be a conveying belt, and the liquid can be water.

[0041] The pipeline 100 described above is used in practice, first, the spraying assembly 30 sprays liquid towards the transmission assembly 20, because the transmission assembly 20 can continuously run without stopping, so that the liquid sprayed by the spraying assembly 30 uniformly covers the surface of the transmission assembly 20, so that the liquid softens the foreign matters adhered on the transmission assembly 20, then the transmission assembly 20 continuously runs and drives the softened foreign matters to the scraper assembly 40, finally, the scraper assembly 40 scrapes the softened foreign matters from the transmission assembly 20, so that the foreign matters adhered on the transmission assembly 20 do not rub or collide with the workpieces placed on the transmission assembly 20, the workpieces are prevented from being damaged, and the transmission quality of the pipeline 100 is improved.

[0042] Please refer to Figure 1 It can be understood that, in the embodiment, the transmission assembly 20 comprises a first rotating piece 21, a second rotating piece 22 and a transmission piece 23, the first rotating piece 21 and the second rotating piece 22 are arranged at intervals on the rack 10 and are both rotationally connected to the rack 10, the transmission piece 23 is sleeved on the first rotating piece 21 and the second rotating piece 22, the transmission piece 23 rotates under the driving of the first rotating piece 21 and the second rotating piece 22, and the spraying assembly 30 and the scraper assembly 40 are arranged adjacent to the first rotating piece 21 and are located on the upper and lower sides of the transmission piece 23.

[0043] The spraying assembly 30 located above the conveying member 23 sprays liquid to the conveying member 23 at the position of the first rotating member 21, then the conveying member 23 is moved to the first rotating member 21 through the second rotating member 22, and finally the scraper assembly 40 located at the conveying member 23 scrapes off the softened foreign matters at the position of the first rotating member 21. In this way, by arranging the spraying assembly 30 and the scraper assembly 40 adjacent to the first rotating member 21 and on the upper and lower sides of the conveying member 23, the movement distance of the conveying member 23 between the spraying assembly 30 and the scraper assembly 40 is increased, so that the liquid sprayed to the conveying member 23 has enough time to soften the foreign matters, and the scraper assembly 40 can stably scrape off the foreign matters from the conveying member 23.

[0044] For further understanding Figure 1 In some embodiments, the spraying assembly 30 comprises a spraying member 31, a liquid inlet member 32 and a switch valve 33. The spraying member 31 is arranged above the conveying assembly 20 and connected with the rack 10, the liquid inlet member 32 is communicated with an external liquid supply member, the liquid inlet member 32 is used to deliver the liquid provided by the external liquid supply member to the spraying member 31, and the switch valve 33 is communicated with the spraying member 31 and the liquid inlet member 32 respectively, the switch valve 33 is used to open or close the flow passage between the liquid inlet member 32 and the spraying member 31, so as to control the spraying member 31 to spray liquid. For example, the liquid inlet member 32 can be any water inlet part, water inlet body or similar water inlet pipe which can be communicated with the external liquid supply member and the switch valve 33, such as a hollow pipe, and the switch valve 33 can be any switch part, switch body or similar switch member which can open or close the flow passage between the liquid inlet member 32 and the spraying member 31, such as a hydrophobic electromagnetic valve.

[0045] In this way, by arranging the specific structure of the spraying assembly 30, the switch valve 33 opens or closes the flow passage between the liquid inlet member 32 and the spraying member 31 according to the cleaning requirement of the flow line 100, so as to control the spraying member 31 to timely spray liquid to the conveying assembly 20, thereby ensuring that the spraying assembly 30 stably softens the foreign matters adhered to the conveying assembly 20.

[0046] For further understanding Figure 1 In some embodiments, the spraying member 31 comprises a support body 311, a communication body 312 and a plurality of spraying bodies 313. The support body 311 is connected with the rack 10, the communication body 312 is arranged above the conveying assembly 20 and connected with the support body 311, the communication body 312 is communicated with the switch valve 33, the communication body 312 is used to receive the liquid delivered by the liquid inlet member 32, and the plurality of spraying bodies 313 are arranged at intervals and communicated with the communication body 312, the plurality of spraying bodies 313 are used to spray the liquid delivered to the communication body 312 to the surface of the conveying assembly 20. For example, the spraying body 313 can be an atomizing nozzle.

[0047] Thus, the support body 311 is connected with the communicating body 312, so that the support body 311 supports the communicating body 312 and the plurality of spraying bodies 313, and ensures that the spraying member 31 stably sprays the liquid. In addition, the plurality of spraying bodies 313 are respectively communicated with the communicating body 312, so that the plurality of spraying bodies 313 simultaneously spray the liquid to different positions on the surface of the conveying assembly 20, so as to increase the spraying area of the spraying member 31, and facilitate the liquid sprayed by the spraying assembly 30 to completely cover the surface of the conveying assembly 20, so as to ensure that the liquid softens all foreign matters adhered on the conveying assembly 20.

[0048] In some embodiments, the spraying assembly 30 comprises a controller 34, which is electrically connected with the on-off valve 33. The controller 34 is used to control the on-off valve 33 to open or close the flow passage between the liquid inlet member 32 and the spraying member 31 according to preset time information. For example, the controller 34 can be a time relay. It can be understood that the above-mentioned preset time information refers to that the controller 34 controls the on-off valve 33 to open the flow passage between the liquid inlet member 32 and the spraying member 31 every first predetermined time, and ensures that the on-off valve 33 is continuously opened for a second predetermined time.

[0049] Thus, the controller 34 is electrically connected with the on-off valve 33, so that the controller 34 controls the on-off valve 33 to open or close the flow passage between the liquid inlet member 32 and the spraying member 31 according to the preset time information, which avoids that the spraying member 31 continuously sprays the liquid to the conveying assembly 20, and thus facilitates to reduce the cleaning cost of the assembly line 100.

[0050] Please refer to Figure 1 In some embodiments, the scraping assembly 40 comprises a first scraping member 41 and a second scraping member 42. The first scraping member 41 and the second scraping member 42 are arranged below the conveying assembly 20 and are both connected to the rack 10. The first scraping member 41 is away from the spraying assembly 30 relative to the second scraping member 42 along the direction in which the conveying assembly 20 points to the spraying assembly 30. The first scraping member 41 and the second scraping member 42 are both abutted to the conveying assembly 20, and are used to sequentially scrape off the softened foreign matters and liquid from the conveying assembly 20.

[0051] Thus, by setting the specific structure of the scraper assembly 40, the softened foreign matter is first scraped off the conveying assembly 20 by the first scraper 41, so as to avoid the damage of the workpiece in the conveying process due to the adhesion of the foreign matter on the conveying assembly 20. The liquid adhered on the conveying assembly 20 is scraped off by the second scraper 42, so as to keep the surface of the conveying assembly 20 dry, prevent the workpiece from slipping and deviating due to the liquid on the surface of the conveying assembly 20 in the conveying process, and ensure the stable conveying of the workpiece by the cleaned conveying assembly 20. In addition, since the foreign matter is a solid matter, the foreign matter forms a certain height on the surface of the conveying assembly 20, and the liquid is a liquid matter, so that the liquid forms a plane on the surface of the conveying assembly 20, and the height of the liquid is lower than that of the foreign matter. By setting the first scraper 41 to be away from the spraying assembly 30 relative to the second scraper 42 in the direction of the conveying assembly 20 pointing to the spraying assembly 30, the first scraper 41 and the second scraper 42 form a certain height difference, so that the pressing force of the second scraper 42 relative to the first scraper 41 applied to the conveying assembly 20 is greater, and the first scraper 41 and the second scraper 42 stably scrape the foreign matter and the liquid adhered on the conveying assembly 20 in turn.

[0052] Referring to Figure 1 and Figure 2 In some embodiments, the first scraper 41 and the second scraper 42 each include a connecting body 411, a scraper body 412, and an adjusting body 413. The connecting body 411 is arranged below the conveying assembly 20 and connected with the rack 10. The scraper body 412 abuts against the conveying assembly 20 and is rotationally connected with the connecting body 411. The adjusting body 413 is threadedly connected with the connecting body 411 and abuts against one side of the scraper body 412. The adjusting body 413 is used to adjust the scraper body 412 to a preset inclination angle, so that the scraper body 412 scrapes the softened foreign matter or liquid from the conveying assembly 20. Exemplarily, the adjusting body 413 can be a bolt.

[0053] Thus, by setting the specific structure of the first scraper 41 and the second scraper 42, the operator can drive the adjusting member to rotate according to the cleaning requirement of the conveying assembly 20, so as to push the adjusting body 413 against the scraper body 412 and adjust the scraper body 412 to a preset inclination angle, thereby stably scraping the softened foreign matter or liquid from the conveying assembly 20.

[0054] Referring to Figure 2In some embodiments, the scraper body 412 comprises a main body portion 4121, a scraper portion 4122 and a guide portion 4123, the main body portion 4121 is rotationally connected with the connecting body 411 and abuts against the adjusting body 413, the scraper portion 4122 is obliquely arranged relative to the main body portion 4121 and abuts against the conveying assembly 20, the scraper portion 4122 is connected with one end of the main body portion 4121, the guide portion 4123 is obliquely arranged relative to the main body portion 4121 and connected with the other end of the main body portion 4121, the scraper portion 4122 is used to scrape off foreign matters or liquid from the surface of the conveying assembly 20, so that the scraped off foreign matters and liquid slide to the preset area through the main body portion 4121 and the guide portion 4123.

[0055] In this way, by arranging the scraper portion 4122 obliquely relative to the main body portion 4121, a preset angle is formed between the scraper portion 4122 and the conveying assembly 20, which facilitates the scraper portion 4122 to guide the foreign matters or liquid to slide along the surface of the scraper portion 4122, reduces the friction and damage to the surface of the conveying assembly 20, by arranging the guide portion 4123 obliquely relative to the main body portion 4121, it is beneficial for the guide portion 4123 to guide the scraped off foreign matters or liquid to smoothly slide to the preset area, which facilitates the centralized collection and treatment of the foreign matters and liquid.

[0056] Please refer to Figure 1 and Figure 2 In some embodiments, the connecting body 411 comprises two fixed portions 4111 and a connecting portion 4112, the two fixed portions 4111 are arranged on both sides of the conveying assembly 20 and are connected with the rack 10, the two fixed portions 4111 are rotationally connected with both sides of the scraper body 412 respectively, the two fixed portions 4111 are used to support the scraper body 412, the connecting portion 4112 is arranged below the conveying assembly 20, both ends of the connecting portion 4112 are connected with the two fixed portions 4111 respectively, the connecting portion 4112 is threadedly connected with the adjusting body 413, and the connecting portion 4112 is used to support the adjusting body 413.

[0057] In this way, by arranging the specific structure of the connecting body 411, the fixed portions 4111 and the connecting portion 4112 support the scraper body 412 and the adjusting body 413 respectively, so that the connecting body 411 limits the installation position of the scraper body 412, and ensures that the scraper body 412 stably scrapes off the adhered foreign matters and liquid from the conveying assembly 20.

[0058] Please refer to Figure 3 In some embodiments, the flow line 100 further comprises a collecting member 50, the collecting member 50 is arranged below the scraper assembly 40 and is connected with the rack 10, and the collecting member 50 is used to collect the foreign matters scraped off by the scraper assembly 40.

[0059] In this way, by arranging the above-mentioned collecting member 50, the collecting member 50 collects the foreign matters scraped off by the scraper assembly 40, which is beneficial for the centralized treatment of the scraped off foreign matters.

[0060] Please continue to see Figure 3 In some embodiments, the pipeline 100 further comprises a shield 60, which covers the spraying assembly 30 and is connected with the rack 10, and the shield 60 is used to protect the spraying assembly 30.

[0061] In this way, by setting the shield 60, the shield 60 protects the spraying assembly 30, avoids the spraying assembly 30 from being disturbed by external factors, and ensures the normal operation of the spraying assembly 30. In addition, the shield 60 can also block the liquid sprayed by the spraying assembly 30 from splashing around.

[0062] The working process of the pipeline 100 is as follows:

[0063] Firstly, the controller 34 controls the on-off valve 33 to open the flow passage between the liquid inlet 32 and the spraying member 31, and the spraying member 31 sprays liquid towards the conveying assembly 20. Since the conveying assembly 20 can run continuously without stopping, the liquid sprayed by the spraying assembly 30 uniformly covers the surface of the conveying assembly 20, so as to soften the foreign matter adhered to the conveying assembly 20.

[0064] Then, the conveying assembly 20 continues to run and drives the softened foreign matter to the scraper assembly 40.

[0065] Finally, the first scraper 41 first scrapes the softened foreign matter off the conveying assembly 20, and the second scraper 42 then scrapes the liquid off the conveying assembly 20, so as to avoid the foreign matter adhered to the conveying assembly 20 from rubbing or colliding with the workpiece placed on the conveying assembly 20, thereby preventing the workpiece from being damaged and improving the conveying quality of the pipeline 100.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application.
