[0030] like Figure 1 , which is a schematic diagram of the structure of a glass tube feeding device in one embodiment of the utility model. In this embodiment, the glass tube feeding device includes a vibration plate 1, a feeding track 2, a visual detection component 3, a recovery bin 4 and a conveying component 5.

[0031] Among them, the various components of this embodiment can be installed on a frame, and the vibration plate 1 is used to align the glass tubes 6 by vibration and transport them to the feeding track 2. The glass tubes 6 can be placed in the vibration plate 1 manually, or a silo can be set on the vibration plate 1, and a straight vibrator can be installed at the bottom of the silo. The feeding track 2 can be plate-shaped, and a visual inspection component 3 and a recovery silo 4 can be set on the feeding track 2. The visual inspection component 3 includes a screening camera and a ring light source arranged toward the feeding track 2. The screening camera takes a picture of the glass tubes 6 on the feeding track 2 and inspects its appearance, thereby screening out defective glass tubes 6, and then transferring the defective glass tubes 6 from the feeding track 2 to the recovery silo 4. Qualified glass tubes 6 are conveyed to the conveying component 5 along the feeding track 2, and the conveying component 5 conveys the glass tubes 6 to the device corresponding to the next step.

[0032] like Figure 2 , which is a schematic diagram of the structure of the loading track in this embodiment. A groove 21 for accommodating the movement of the glass tube 6 is provided on the loading track 2, and the track outlet of the vibration plate 1 is connected to the entrance of the groove 21.

[0033] The width of the groove 21 can be customized according to the diameter of the glass tube 6, so that the width of the groove 21 is slightly larger than the width of the glass tube 6, and the glass tube 6 can be arranged in only one row in the groove 21 and can move freely along the groove 21. The depth of the groove 21 can be set as needed to prevent the groove 21 from being too shallow and affecting the stability of the movement of the glass tube 6 in the groove 21. The track outlet of the vibration plate 1 is connected to the entrance of the groove 21, and the glass tube 6 can be guided to the groove 21 of the feeding track 2 in sequence and arranged in a row, so that the glass tube 6 can be transported to the visual inspection component 3 in sequence for inspection.

[0034] An inspection position 22 is provided on the feeding track 2 , and a visual inspection component 3 is provided above the inspection position 22 for inspecting the appearance of the glass tube 6 .

[0035] Among them, the detection position 22 is a station on the feeding track 2 for sequentially detecting the glass tube 6. The top of the station is unobstructed, and the appearance of the glass tube 6 can be exposed to the visual inspection component 3 from above, which is convenient for the visual inspection component 3 to detect the appearance of the glass tube 6. The visual inspection component 3 may include an image acquisition unit and a processing unit. The image acquisition unit acquires the appearance image of the glass tube 6. The processing unit processes the appearance image of the glass tube 6 according to the product appearance requirements, screens out unqualified glass tubes 6, and sends a signal to the control unit of the glass tube feeding device. The control unit of the glass tube feeding device may be a programmable logic controller, etc.

[0036] Figure 3 It is a partial side view of the glass tube feeding device, as shown in Figure 2 and Figure 3 As shown, a recovery position is also provided on the feeding track 2, and the recovery position is downstream of the detection position 22; an air inlet hole 23 penetrating the groove 21 is opened at the recovery position, and the width of the air inlet hole 23 is smaller than the width of the glass tube 6; the entrance of the recovery bin 4 is arranged on the upper side of the recovery position, and a duckbill nozzle 7 is arranged below the recovery position, and the nozzle of the duckbill nozzle 7 is connected to the bottom of the air inlet hole 23, which is used to spray toward the entrance direction of the recovery bin 4.

[0037] Among them, the air inlet 23 runs through the feeding track 2, so that the duckbill nozzle 7 can spray air from the bottom to the groove 21. When the unqualified glass tube 6 moves to the recovery position, the duckbill nozzle 7 sprays air to lift it off the feeding track 2 and blow it into the recovery bin 4. The jet angle of the duckbill nozzle 7 can be designed according to the entrance position of the recovery bin 4, so that the glass tube 6 can stably enter the recovery bin 4. Preferably, the size of the duckbill nozzle 7 corresponds to the size of the air inlet 23, and the two are in close contact to improve the air tightness, so that the gas acting on the glass tube 6 has enough power to lift the glass tube 6. The recovery bin 4 is arranged on one side of the feeding track 2. Preferably, an inclined surface is arranged on the side of the recovery position groove close to the recovery bin 4. The inclined surface is used to guide the glass tube 6 so that the glass tube 6 can fly out of the recovery bin 4 at an angle, further improving the accuracy of the glass tube 6 entering the recovery bin 4. The width of the air inlet 23 is smaller than the width of the glass tube 6, so that the qualified glass tube 6 can pass smoothly through the recovery position, so that the loading track 2 can be stably transported. The glass tube 6 has a smooth surface and is cylindrical, which is easy to roll. Compared with the sorting mechanism that removes unqualified materials from the bottom or side of the track, the loading track 2 in this embodiment has more stable transportation stability, which can reduce the probability of the glass tube 6 falling and improve the working efficiency of the device.

[0038] like Figure 3As shown, the conveying assembly 5 includes a conveying pipe 51, the inlet of the conveying pipe 51 is connected to the outlet of the loading track 2, and an air intake pipe 52 is connected to the side of the conveying pipe 51, and the air intake pipe 52 is used to supply air to the conveying pipe 51 to move the glass tube 6 in the conveying pipe 51.

[0039] The inner diameter of the delivery pipe 51 is slightly larger than the diameter of the glass tube 6, and the glass tube 6 can move therein under the action of air pressure. The air inlet pipe 52 is connected to an air pump or other air supply device, and an air pressure regulating mechanism can also be provided to control the air pressure of the air inlet pipe 52. The cross-sections of the delivery pipe 51 and the glass tube 6 are both circular, so the delivery pipe 51 can be well adapted to the glass tube 6 and transport the glass tube 6 over a longer distance.

[0040] In summary, the glass tube feeding device provided in this embodiment can overcome the problems in the prior art of feeding through a clamping mechanism, which is inconvenient to clamp, easy to fall, and easy to damage the outer shell of the glass tube 6. It has a high degree of automation, can save labor costs, improve production efficiency, and reduce the breakage rate of the glass tube 6.

[0041] like Figure 2 As shown, in this embodiment, two position control nozzles 8 are further provided on the feeding track 2, and the position control nozzles 8 are respectively arranged at the upstream positions of the detection position 22 and the recovery position.

[0042] When the vibrating plate 1 transfers the glass tube 6 to the upper material track 2, the distance between the front and rear glass tubes 6 is difficult to control, and the two glass tubes 6 may be in close contact. However, the steps of visual inspection and removal of unqualified glass tubes 6 both require operation on individual glass tubes 6, so the position of the glass tube 6 needs to be controlled by the position control nozzle 8.

[0043] like Figure 3 As shown, in this embodiment, the position control nozzle 8 is tiltedly arranged above the groove 21 to spray air into the glass tubes 6 in the groove 21 so that there are spacings between the glass tubes 6 in the groove 21 .

[0044] The position control nozzle 8 is preferably conical, and can accurately spray air into the groove 21, pushing the glass tube 6 to move forward quickly, so that it has a certain distance from the rear glass tube 6. The position control nozzle 8 can use an air pump to supply air, and an electromagnetic valve is installed to control the switch of the position control nozzle 8. The position control nozzle 8 is tilted above the groove 21, and has an angle with the feeding direction, and the angle can be adjusted as needed.

[0045] In this embodiment, the feeding track 2 is also equipped with two groups of optical fibers, which are respectively arranged between the detection position 22 and the position control nozzle 8, and between the recovery position and another position control nozzle 8.

[0046] The optical fiber can be installed in the optical fiber installation hole, and the optical fiber installation hole penetrates the feeding track 2 from the side, so that the light emitted by the optical fiber can pass through the groove 21 to detect the glass tube 6 in the groove 21. The position control nozzle 8 can work according to the signal collected by the optical fiber, spray the tail of the glass tube 6, accelerate it to enter the detection position 22 or the recovery position, and generate a certain distance from the rear glass tube 6.

[0047] This embodiment detects the glass tube 6 by means of a radiated optical fiber and controls the position and spacing of the glass tube 6 by means of an air jet, thereby reducing mechanical collisions and the risk of damage to the glass tube 6 during the loading process. The structure is simple, maintenance is easy, and the working stability and production efficiency are high.

[0048] like Figure 4 As shown, it is a schematic diagram of the installation of the pressing plate in this embodiment. In this embodiment, the feeding track 2 is covered with a pressing plate 9, and the pressing plate 9 is provided with openings at positions corresponding to the detection position 22, the recovery position and the position control nozzle 8.

[0049] The pressing plate 9 and the groove 21 can form a channel for accommodating the glass tube 6, preventing the glass tube 6 from falling, and further improving the transmission stability of the glass tube 6 on the feeding track 2. In addition, the channel has a certain airtightness, which can stabilize the airflow sprayed by the position control nozzle 8. The opening corresponding to the detection position 22 and the opening corresponding to the recovery position can completely expose the entire glass tube 6, so that the glass tube 6 can be visually inspected at the detection position 22, and can be separated from the feeding track 2 and enter the recovery bin 4 at the recovery position.

[0050] In this embodiment, the pressing plate 9 is provided with a long strip opening 91 at a position corresponding to the position control nozzle 8 . The long strip opening 91 is arranged parallel to and directly above the groove 21 , and its width is smaller than the diameter of the glass tube 6 .

[0051] Among them, the long strip opening 91 can facilitate the positioning nozzle 8 to adjust the jet angle and position, and its width is smaller than the diameter of the glass tube 6 to prevent the glass tube 6 from falling due to excessive airflow, thereby increasing the gas pressure sprayed by the positioning nozzle 8 and further increasing the moving speed of the glass tube 6 under the action of the positioning nozzle 8, thereby improving work efficiency.

[0052] In this embodiment, the loading track 2 includes a fixed track and a direct vibration track. A linear feeder is arranged at the bottom of the direct vibration track, and the fixed track is used to connect the vibration plate 1 and the direct vibration track; the visual detection component 3 is arranged above the direct vibration track, and the positioning nozzle 8 at the upstream position of the visual detection component 3 is arranged on the fixed track.

[0053] Among them, the fixed track can be installed through a fixed bracket, and a certain distance is reserved between the fixed track and the direct vibration track to prevent the direct vibration track from colliding with the fixed track during the vibration process. The fixed track is used to receive the neatly arranged glass tubes 6 on the vibration disk 1, and the glass tubes 6 on the fixed track are moved by the thrust of the subsequent glass tubes 6. The position control nozzle 8 is arranged on the fixed track to increase the spacing between the glass tubes 6. After the glass tubes 6 are moved to the direct vibration track, it is convenient to carry out visual inspection. The direct vibration track realizes the movement of the glass tubes 6 through a linear feeder, which can maintain a large spacing, thereby facilitating the removal of unqualified glass tubes 6. When unqualified glass tubes 6 appear, the position control nozzle 8 arranged at the upstream position of the recovery position can spray them, further adjust the spacing between the unqualified glass tubes 6 on the direct vibration track and the glass tubes 6 before and after it, and improve the efficiency of recovering unqualified glass tubes 6.

[0054] like Figure 5 As shown, it is a cross-sectional installation diagram of the fixed block in this embodiment. In this embodiment, the conveying assembly 5 also includes a fixed block 53, and the fixed block 53 is provided with an inclined hole 54 inclined downward, and the entrance of the inclined hole 54 is trumpet-shaped, which is used to dock with the outlet of the straight vibration track; the outlet of the inclined hole 54 is connected to a three-way component 55, and the outlet of the three-way component 55 is connected to the conveying pipeline 51, and the side inlet is connected to the air intake pipe 52.

[0055] Among them, a certain gap is set between the fixed block 53 and the straight vibration track, the direction of the inclined hole 54 is tilted downward, and the entrance of the inclined hole 54 is trumpet-shaped, which can facilitate the glass tube 6 to enter the inclined hole 54 and move to the conveying pipe 51 through the three-way component 55 under the action of gravity. After passing through the three-way component 55, the glass tube 6 can be accelerated by the air intake pipe 52 to improve the transportation efficiency.

[0056] In this embodiment, a through hole penetrating the inclined hole 54 is further provided on the fixing block 53 , and a through-hole is installed in the through hole.

[0057] In this embodiment, the fixing block 53 is mounted on the frame via an XY fine-tuning module.

[0058] Among them, the XY fine-tuning module can further improve the coordination between the inclined hole 54 of the fixing block 53 and the outlet of the straight vibration track, thereby preventing the glass tube 6 from being blocked when entering the fixing block 53 from the straight vibration track.

[0059] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
