[0040] like Figures 1 to 11 As shown, the present invention provides a high borosilicate glass tube grading device, comprising:

[0041] Cleaning module 2: used to clean the glass tube; when the cleaning is completed, the cleaned glass tube is transported to the grading module 3.

[0042] Grading module 3: The glass tubes are graded and screened according to color, the color of each glass tube screened out by graded and screened is recorded, and each glass tube is sorted to form a color queue; after sorting, the glass tubes are moved in order in the color queue and pass through each discharge port in turn; according to different grading modes, the glass tubes are discharged when they are transported to the corresponding discharge port.

[0043] The grading modes include: same color grading mode, in which glass tubes of the same color are transported to corresponding discharge ports; mixed color grading mode, in which several glass tubes of the same or different colors are transported to corresponding discharge ports.

[0044] When the same color grading mode is adopted, when the glass tube with the corresponding serial number in the color queue is transported to the discharge port, the color of the glass tube corresponding to the serial number is matched with the predetermined color of the corresponding discharge port; if the match is successful, the discharge port is opened to allow the glass tube to fall from the discharge port; the falling status of the glass tube in the queue and the color information of the remaining glass tubes in the queue are updated in real time; otherwise, the discharge port is not opened to allow the glass tube to continue to move to the next discharge port.

[0045] When the color mixing and grading mode is adopted, the number of colors is set to n, and the number of feeding ports is set to N, where N ≥ n. A storage list is created for each feeding port in the system to store the glass tubes of a certain color that have passed through the feeding port and the number thereof; for example, in the storage list of a certain feeding port, there are 1 red glass tube, 1 yellow glass tube, and 1 blue glass tube missing. In the initial state, or when the storage list completes the collection of glass tubes, the storage list of the corresponding feeding port is reset.

[0046] If the storage list of the current feed port lacks the glass tube of the corresponding color in the color queue, the feed port will be opened to receive the glass tube; after receiving, the glass tube will be removed from the color queue and the color will be recorded in the storage list of the current feed port. On the contrary, if the storage list of the current feed port is no longer lacking a glass tube of a certain color in the color queue, the feed port will not be opened, and the glass tube will continue to move to the next feed port. When the list of the feed port contains all the glass tubes required by the mixed color mode, the glass tubes will be packaged; at the same time, the storage list of the feed port will be reset to facilitate receiving a new group of glass tubes.

[0047] A priority score is set for each feeding port in the system, and the priority score includes: the frequency of use of the feeding port (F), the color matching degree between the glass tubes to be stored in the storage list of the corresponding feeding port and the glass tubes of the corresponding color in the color queue (M), and the remaining capacity of the storage list of the corresponding feeding port (C); wherein, the higher the frequency of use, the lower the priority, so as to avoid excessive use of a certain feeding port; if the color matches and the feeding port is not full, the matching degree is high and the priority is increased; the larger the remaining capacity, the higher the priority, so as to avoid full load of the feeding port.

[0048] The priority score (P) of each unloading port is calculated by the following formula: P = (M × (1 + C)) ÷ F. If the color in the color queue is the same as the color required in the storage list corresponding to the corresponding unloading port, then M = 1, that is, when the storage list is not full, it is sorted according to the priority score; conversely, when the colors are different, then M = 0, that is, when the storage list is full, the unloading of glass tubes to the corresponding unloading port is suspended to reserve time for packaging, and the storage list is reset after the predetermined time. The predetermined time is set according to the packaging time, generally 5-10 seconds.

[0049] The priority score is updated in real time. Whenever a set of storage lists is full, the weight of the usage frequency F increases. Whenever a new glass tube enters the corresponding discharge port, the remaining capacity C decreases. If the storage list of a discharge port is full, C=0, and the storage list is reset after a predetermined time. According to the priority score P calculated in real time, all discharge ports are sorted, and the discharge port with the highest priority score gives priority to receiving glass tubes of the corresponding color in the color queue.

[0050] When a certain discharge port fails, the discharge port will not discharge materials, and other discharge ports will be prioritized and scored; when there are multiple glass tubes of colors that cannot be matched with the corresponding discharge ports in the color queue, all discharge ports will not be opened, and the corresponding glass tubes in the color queue will be moved to the collection module, and then the glass tubes in the collection module will be manually sent back to the grading module 3.

[0051] As a supplement, a photoelectric sensor or a position sensor may be provided at the entrance of the discharge port to detect the displacement state of the glass tube and ensure that the glass tube actually falls into the discharge port.

[0052] The cleaning module 2 includes: a high-pressure gas source 21 fixedly installed inside the machine 1; an air nozzle 22 and an air bag 23 connected to the high-pressure gas source 21 through a connecting pipe; a mounting seat 24 installed on the top of the machine 1, and the air nozzle 22 is slidably installed on the mounting seat 24; the connecting pipe is composed of a connecting section and a telescopic section connected to the connecting section, the air inlet end of the telescopic section is connected to the connecting pipe, and the air outlet end of the telescopic section is connected to a sliding shell 25, the sliding shell 25 is slidably installed on the mounting seat 24, and the sliding shell 25 is provided with an air outlet hole in the horizontal direction and a mounting hole in the longitudinal direction. The air nozzle 22 is installed in the mounting hole; the sliding direction of the sliding shell 25 is the up-down direction, and the sliding shell 25 is located on the side of the mounting seat 24 close to the middle of the machine 1; the bottom of the sliding shell 25 is connected to a return spring 26, and the other end of the return spring 26 is connected to the machine 1; a limit plate 27 is also fixedly installed on one side of the mounting seat 24, and the air bag 23 is installed in the limit plate 27, and the air bag 23 is connected to the air outlet hole; there are two air bags 23, and they are arranged symmetrically in an arc shape; when the high-pressure gas source 21 is working, the gas flows to the sliding shell through the connecting pipe. The sliding shell 25 slides downward because the air outlet rate of the sliding shell 25 is lower than the air inlet rate, thereby driving the air nozzle 22 to slide downward. During the sliding process of the air nozzle 22, the relative position of the air nozzle 22 with the glass tube changes, so that the blowing direction changes relatively. When the air nozzle 22 slides to the lowest point, it is close to the coaxial center with the air bag 23. At the same time, the gas flows into the air bag 23 to expand the air bag 23, so that the two symmetrical air bags 23 are squeezed close to each other, which can fix the glass tube. Using the air bag 23 to fix the glass tube can avoid pinching The glass tube is damaged during the holding process; at this time, the air nozzle 22 can spray air to the outer wall and inner wall of the glass tube, thereby cleaning the glass tube; that is, while fixing the glass tube, the large particles of impurities attached to the inner and outer walls of the glass tube are cleaned by the air nozzle 22, and the air nozzle 22 can also be placed on the glass tube; when the cleaning is completed, the high-pressure air source 21 stops working, and the reset spring 26 drives the sliding shell 25 to reset, thereby driving the air nozzle 22 to separate from the glass tube. At the same time, the air bag 23 contracts, loosens the glass tube, and makes the glass tube slide down along the machine 1. In addition, since the jet range of the air nozzle 22 is much larger than the aperture of the glass tube, slight errors will not affect the cleaning effect. Secondly, the air blowing cleaning is mainly to remove large particles of impurities attached to the inner and outer walls of the glass tube, and even if there is a trace of dust residue, it will not affect the glass tube.

[0053] The grading module 3 includes: a mounting frame 31 installed on the top of the mounting base 24, a detection camera 32 is installed on the mounting frame 31, a light source 33 is installed at the shooting end of the detection camera 32, the light source 33 is used to provide a stable lighting environment, and the detection camera 32 is used to detect the glass tube; in this embodiment, the detection includes at least color detection; it may also include quality detection of the glass tube. The content of quality detection does not fall within the protection scope of the present invention and will not be described in detail here.

[0054] An n-shaped frame 11 is also installed on the top of the machine 1, and the n-shaped frame 11 is located on the unloading side of the mounting seat 24; a through hole is opened on the top of the n-shaped frame 11, and a stopper 12 is slidably installed in the through hole; a second motor 13 is also fixedly installed on the top of the n-shaped frame 11, and the output end of the second motor 13 passes through the n-shaped frame 11 and is threadedly connected to the stopper 12, which is used to drive the stopper 12 to slide up and down along the through hole through the rotation of the second motor 13; the stopper 12 is used to limit the number of glass tubes passing through the stopper 12 on the one hand, and on the other hand, it is used to adjust the posture of the glass tube to avoid the position of the glass tube from being offset when it slides off the airbag 23, which makes it difficult for the glass tube to fall into the unloading port.

[0055] The packaging module 4 includes: a mounting plate 41 mounted on the unloading side of the n-shaped frame 11, a rotating member 42 rotatably mounted on the top of the mounting plate 41, a first motor 43 that drives the rotating member 42 to rotate, and a slide rail 44 mounted below the mounting plate 41, a slider 45 slidably mounted on the top of the slide rail 44, and a limit block 46 fixedly mounted on the top of the slider 45. The limit block 46 is used to limit the packaging box, which is used to package glass tubes. When the rotating member 42 rotates clockwise along the mounting plate 41, a unloading port is formed.

[0056] The rotating member 42 includes: a rotating plate 421 rotatably connected to the mounting plate 41, and a push rod 422 rotatably mounted on the bottom of the rotating plate 421; the rotating shaft 4221 of the push rod 422 is located on a side close to the n-shaped frame 11, so that the push rod 422 can rotate clockwise along the rotating shaft 4221 and automatically droop under the action of gravity, and when the push rod 422 is in vertical contact with the rotating plate 421, it cannot rotate counterclockwise; a plurality of abutment blocks 451 are installed on one side of the slider 45, and when the push rod 422 rotates clockwise, it abuts against the abutment blocks 451; when a certain unloading port needs to unload a glass tube, the first motor 43 drives the rotating plate 421 to rotate, and the glass tube slides down along the rotating plate 421 into the packaging box. At the same time, the push rod 422 abuts against a certain abutment block 451, driving the slider 45 to slide, thereby driving the packaging box. The box loading slides to facilitate the glass tubes to slide into the packaging box in sequence; after unloading is completed, the first motor 43 drives the rotating plate 421 to rotate in the opposite direction, so that the rotating plate 421 is reset to close the unloading port. In the reset state, the rotating plate 421 and the top surface of the mounting plate 41 are in the same straight line, which is convenient for the glass tubes to slide through; during the counterclockwise rotation of the rotating plate, the push rod 422 contacts the subsequent abutment block 451. Due to the design of the rotating shaft 4221 of the push rod 422, the push rod 422 swings when contacting the abutment block 451. On the one hand, the push rod 422 can avoid interference with the abutment block 451. On the other hand, the push rod 422 can pass through the abutment block 451, and then droop into the gap between the abutment block 451 and the abutment block 451 after it, so as to push the slider 45 to slide during the next clockwise rotation.

[0057] In addition, when a set of storage lists is full, the slider 45 needs to be reset. The slider 45 can be reset manually, or a motor can be used in conjunction with a screw rod or a telescopic cylinder to drive the slider 45 to reset. The specific design is a conventional setting.

[0058] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the prior art. Machinery, parts and equipment all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here. The content not described in detail in this specification belongs to the prior art known to professional and technical personnel in this field.

[0059] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the appended claims of the present invention.
