[0039] Figures 1 - 19 is the best embodiment of the present utility model. The following will further describe the present utility model in conjunction with the appended Figures 1 - 19 drawings.

[0040] As Figure 1 shown, a shooting inspection machine for detecting defects of glass bottles (hereinafter referred to as the inspection machine) includes a main frame 5 arranged vertically. A door assembly 3 is arranged in the middle of the front side of the main frame 5, and a human-machine interface 2 is arranged in the middle of the door assembly 3. An electrical cabinet 1 is arranged on the top of the main frame 5. A control circuit of the inspection machine is arranged in the electrical cabinet 1, and an alarm lamp connected to the control circuit in the electrical cabinet 1 is also arranged on the top of the electrical cabinet 1.

[0041] Combined with Figures 2 - 3 the drawings, a chain plate bottle conveying mechanism 4 is arranged below the inspection machine. The chain plate bottle conveying mechanism 4 is fixed to the main frame 5 and penetrates through the left and right sides of the inspection machine. Shooting lifting frames 7 are fixed on both sides inside the main frame 5. The bottom of the shooting lifting frame 7 is fixed to the main frame 5. A shooting mechanism 6 is fixed between the tops of the two shooting lifting frames 7 on both sides. The height adjustment of the shooting mechanism 6 is realized through the two shooting lifting frames 7 on both sides. A belt adjustment mechanism 9 is arranged on the outer side of each of the two shooting lifting frames 7 on both sides. A belt bottle conveying mechanism 8 is also suspended between the shooting mechanism 6 and the chain plate bottle conveying mechanism 4. The top of the belt bottle conveying mechanism 8 is fixed to the belt adjustment mechanism 9, and the lower part extends between the shooting mechanism 6 and the chain plate bottle conveying mechanism 4. The height and spacing adjustment of the belt bottle conveying mechanism 8 are realized by the belt adjustment mechanism 9.

[0042] The chain plate bottle conveying mechanism 4 is used to realize the entry and output of glass bottles into and out of the inspection machine. After the glass bottles enter the interior of the inspection machine, they are transported by the belt bottle conveying mechanism 8. The glass bottles are driven by the belt bottle conveying mechanism 8 to pass under the shooting mechanism 6 in sequence. When the glass bottles pass through the shooting mechanism 6, the shooting mechanism 6 takes pictures of the glass bottles, and defect judgment is made based on the images. The glass bottles that have completed shooting are transferred back to the chain plate bottle conveying mechanism 4 again before being transferred out of the inspection machine. Finally, the chain plate bottle conveying mechanism 4 transfers the glass bottles out of the inspection machine.

[0043] As Figure 4 shown, the main frame 5 includes two relatively arranged frames. Two upper fixed beams 10 are relatively arranged at the upper part between the two frames, and two lower fixed beams 12 are relatively arranged at the upper part between the two frames. The two frames are fixed into one body by the two upper fixed beams 10 at the upper part and the two lower fixed beams 12 at the lower part. Each frame includes two vertically arranged columns. A guide rail profile 11 is also fixed on each of the two opposite end faces of the two columns in each frame. The guide rail profile 11 is realized by using a standard profile in the art. Therefore, in each frame, a set of guide rail assemblies are correspondingly formed by the two guide rail profiles 11.

[0044] AsFigure 5 As shown in the figure, the electrical cabinet 1 includes a cabinet body. On the upper parts of both sides of the cabinet body, there are respectively provided electrical cabinet cross braces 17. At the tops of the electrical cabinet cross braces 17 on both sides, there are also respectively provided lifting rings 13. At the two ends of the electrical cabinet cross braces 17, there are provided electrical cabinet fixing plates 16.

[0045] On the lower surface of the cabinet body, a plurality of wire passing plates 18 are installed, which are used to connect the control circuit in the cabinet body with each actuator in the main frame 5. By setting the wire passing plates 18, the sealing performance of the cabinet body is improved on the basis of ensuring the connection of the lines. Two chambers are horizontally spaced in the cabinet body, and the circuit board for setting the control circuit is located at the junction of the upper and lower two chambers. On the back of the cabinet body, there are provided two air-conditioning air ducts 15. One ends of the two air-conditioning air ducts 15 are respectively connected into the corresponding chambers, and the other ends of the two air-conditioning air ducts 15 are respectively docked with the air outlet and the air inlet of the air conditioner 14. Therefore, in the cabinet body, cold air enters the cabinet body from the lower part of the circuit board, and hot air is extracted from the upper part of the circuit board, forming an air flow cycle to realize the cooling of the circuit board.

[0046] As Figures 6 - 7 shown in the figure, the photographing mechanism 6 includes a photographing box body. Inside the photographing box body, along the moving direction of the glass bottle, a reflective bottle mouth detection device 20, an incident bottle mouth detection device 21 and a bottle bottom detection device 22 are sequentially arranged. The photographing directions of the reflective bottle mouth detection device 20, the incident bottle mouth detection device 21 and the bottle bottom detection device 22 are vertically downward. When the glass bottle moves below them, the reflective bottle mouth detection device 20, the incident bottle mouth detection device 21 and the bottle bottom detection device 22 respectively photograph the glass bottle.

[0047] Along the moving direction of the glass bottle, in front of the reflective bottle mouth detection device 20, there is also provided an opposed sensor assembly 19. The opposed sensor assembly 19 includes an opposed sensor and a reflector fixed by a bracket. When the glass bottle is being transported, it first passes through the opposed sensor assembly 19 and triggers it. After the opposed sensor assembly 19 is triggered, it sends a trigger signal into the electrical cabinet 1. The control circuit in the electrical cabinet 1 controls the reflective bottle mouth detection device 20, the incident bottle mouth detection device 21 and the bottle bottom detection device 22 to sequentially photograph the glass bottle according to the moving speed and spacing of the glass bottle and the calculated time.

[0048] As Figure 8 shown in the figure, the photographing lifting frame 7 includes a lifting main frame 23. The front and rear sides of the lifting main frame 23 are bent towards the side part of this inspection machine to form bending parts. The bending parts on the front and rear sides of the lifting main frame 23 will form a space on the outer side of the photographing lifting frame 7 that is convenient for accommodating the belt adjusting mechanism 9. The photographing mechanism 6 is fixed at the opposite inner side surfaces of the two lifting main frames 23 on both sides inside the main frame 5.

[0049] On the upper parts of the bending portions on both sides of the lifting main frame 23, a shooting lifting push rod 25 is vertically fixed respectively. The shooting lifting push rod 25 is fixed to the main frame 5 through a shooting fixing member 26 fixed to the bottom of its outer cylinder. The top of the piston rod of the shooting lifting push rod 25 is fixed to the tops of the bending portions on the front and rear sides of the lifting main frame 23. On the sides of the bending portions on the front and rear sides of the lifting main frame 23, shooting lifting guide blocks 24 are also fixed side by side from top to bottom. The shooting lifting guide blocks 24 are fitted into the guide rail profile 11 to facilitate guiding during the lifting process of the shooting mechanism 6.

[0050] As Figures 9 - 10 shown, the belt adjusting mechanism 9 includes two monomers relatively fixed inside the main frame 5. Each monomer includes a shooting adjusting fixing frame 27 arranged horizontally. The two sides of the shooting adjusting fixing frame 27 form bending surfaces. On the outer end surfaces of the bending surfaces, belt lifting guide blocks 30 are fixed side by side from top to bottom. The belt lifting guide blocks 30 are fitted into the guide rail profile 11 to facilitate guiding during the lifting process of the belt bottle conveying mechanism 8. On the inner sides of the bending surfaces on both sides of the shooting adjusting fixing frame 27, a belt lifting push rod 31 is vertically fixed respectively. The belt lifting push rod 31 is fixed to the main frame 5 through a belt lifting fixing frame 32 fixed to the bottom of its outer cylinder. The top of the piston rod of the belt lifting push rod 31 is fixed to the bottoms of the bending surfaces on both sides of the shooting adjusting fixing frame 27.

[0051] On the outer end surface of the shooting adjusting fixing frame 27, two spacing adjusting push rods 28 are horizontally fixed up and down. The two upper and lower spacing adjusting push rods 28 are arranged staggeredly. At the end parts of the piston rods of each spacing adjusting push rod 28, a connecting plate is respectively arranged. The connecting plate extends through the through groove opened in the shooting adjusting fixing frame 27 to the opposite inner side surfaces of the shooting adjusting fixing frames 27 on both sides of the main frame 5. A movable bracket 35 is respectively fixed at the inner side surface of the shooting adjusting fixing frame 27. When the two spacing adjusting push rods 28 move, the two movable brackets 35 move relatively.

[0052] On the inner side surface of the shooting adjusting fixing frame 27, a spacing adjusting slide rail 33 is arranged. On the back surfaces of the two movable brackets 35, spacing adjusting sliders 34 are respectively arranged. The two spacing adjusting slide rails 33 respectively pass through the spacing adjusting sliders 34 on the back surfaces of the two movable brackets 35. On the surface of each movable bracket 35, a group of fixing brackets 29 are also respectively fixed. The fixing brackets 29 are used to connect with the belt bottle conveying mechanism 8.

[0053] As Figures 11 - 12 shown, the belt bottle conveying mechanism 8 includes two belt bottle conveying monomers with the same structure. In each belt bottle conveying monomer, an upper belt 42 and a lower belt 44 which are arranged in parallel up and down and run synchronously are included. In each belt bottle conveying monomer, a belt lifting box body 37 is vertically arranged respectively.

[0054] Two belt lifting boxes 37 in the same belt bottle conveying unit are respectively fixed to two fixing brackets 29 opposite to the two sides of the shooting adjustment fixing frame 27. Therefore, when the spacing adjustment push rod 28 on the shooting adjustment fixing frame 27 moves, the spacing between the two belt bottle conveying units can be adjusted. When the four belt lifting push rods 31 in the two-side belt adjustment mechanism 9 move synchronously, the overall height of the two belt bottle conveying units can be adjusted.

[0055] At the top of one of the belt lifting boxes 37, there are respectively provided push rod fixing frames 36. On the side of each belt lifting box 37, there is respectively fixed a belt height adjustment push rod 38 through the push rod fixing frame 36. In addition to the overall lifting of the belt bottle conveying unit through the belt adjustment mechanism 9, the lower belt 44 can also be lifted and lowered separately through the belt height adjustment push rod 38, so as to adjust the spacing between the upper belt 42 and the lower belt 44 in each belt bottle conveying unit.

[0056] Combined Figures 13 - 14 , in each belt bottle conveying unit, there are also two bottle conveying outer casings arranged up and down. The two belt lifting boxes 37 in each belt bottle conveying unit are respectively vertically fixed to the upper surface of the upper bottle conveying outer casing. At both ends of the upper bottle conveying outer casing, there are respectively provided an upper driving pulley 48 and an upper driven pulley. The upper belt 42 is sleeved outside the upper driving pulley 48 and the upper driven pulley. At both ends of the lower bottle conveying outer casing, there are respectively provided a lower driving pulley 49 and a lower driven pulley. The lower belt 44 is sleeved outside the lower driving pulley 49 and the lower driven pulley.

[0057] On the side of one of the belt lifting boxes 37, there is also fixed a belt driving mechanism 39 through a driving fixing bracket 40. The belt driving mechanism 39 includes a driving motor and a speed reducer. The output end of the speed reducer is coaxially fixed downward with the upper driving pulley 48. Below the upper driving pulley 48, there is also coaxially fixed a telescopic universal joint 43. The telescopic universal joint 43 extends downward to the lower driving pulley 49 and is coaxially fixed with the lower driving pulley 49. Below the lower bottle conveying outer casing, there is also provided a fixed cylinder seat 45 that is vertically opposite to the lower driving pulley 49 and is used to accommodate the telescopic universal joint 43.

[0058] At the lower part of the belt lifting box 37, there is provided a lower fixing block 47. The lower fixing block 47 enters the inside of the belt lifting box 37 upward, and the bottom of the lower fixing block 47 is fixed to the bottle conveying outer casing. Above the lower fixing block 47 inside the belt lifting box 37, there is provided an upper fixing block 46. The belt height adjustment shaft 41 passes through the lower fixing block 47 and the upper fixing block 46 while being slidable. The bottom of the belt height adjustment shaft 41 penetrates the upper bottle conveying outer casing and then extends to the lower bottle conveying outer casing, and is fixed to the upper surface of the lower bottle conveying outer casing.

[0059] A connecting plate is provided at the bottom of the piston rod of the belt height adjustment push rod 38. The connecting plate passes through the through groove vertically opened on the surface of the belt lifting box body 37 and then enters the inside of the belt lifting box body 37, and is fixed to the belt height adjustment shaft 41 inside the belt lifting box body 37. When the belt height adjustment push rod 38 moves, it drives the belt height adjustment shaft 41 to lift and lower, realizing the adjustment of the distance between the upper and lower bottle conveying outer shell brackets, that is, realizing the adjustment of the distance between the upper belt 42 and the lower belt 44.

[0060] As Figures 15 - 16 shown, the chain plate bottle conveying mechanism 4 includes two chain plate drive outer shells 57 arranged at intervals. An inlet bottle chain plate 50 and an outlet bottle chain plate 55 are respectively arranged on the two chain plate drive outer shells 57. The belt bottle conveying mechanism 8 is located directly above the two chain plate drive outer shells 57 arranged at intervals, and the inlet end of the belt bottle conveying mechanism 8 is docked with the inlet bottle chain plate 50, and the outlet end of the belt bottle conveying mechanism 8 is docked with the outlet bottle chain plate 55.

[0061] A transmission box 54 is arranged at the rear side of the two chain plate drive outer shells 57, and transmission shafts 53 are respectively led out from the two chain plate drive outer shells 57 and connected into the transmission box 54. Combining Figure 17 , chain plate drive sprockets 60 are coaxially fixed on the two transmission shafts 53 respectively. The chain plate drive sprockets 60 on the two transmission shafts 53 are respectively meshed with the inlet bottle chain plate 50 or the outlet bottle chain plate 55. After the two transmission shafts 53 are connected into the transmission box 54, a chain plate transmission sprocket 58 is respectively fixed on each of them, and the chain plate transmission sprockets 58 at both ends are connected by a chain plate transmission chain 59.

[0062] One of the inlet bottle chain plate 50 and the outlet bottle chain plate 55 is the driving chain plate. Taking the inlet bottle chain plate 50 as the driving chain plate as an example: when the inlet bottle chain plate 50 moves through its corresponding driving mechanism, it drives the corresponding transmission shaft 53 to rotate through the chain plate drive sprocket 60. When this transmission shaft 53 rotates, it drives the other transmission shaft 53 to rotate through the chain plate transmission sprocket 58 and the chain plate transmission chain 59 in the transmission box 54, so as to drive the outlet bottle chain plate 55 to run synchronously.

[0063] Counting sensors 51 are fixed on the surfaces of the two chain plate drive outer shells 57 through oppositely arranged brackets, and safety baffles 52 are also fixed on the sides of the counting sensors 51. An encoder 56 is also arranged at the end of the transmission shaft 53 corresponding to the inlet bottle chain plate 50.

[0064] As Figures 18 - 19As shown, the door assembly 3 includes an upper door beam 62 and a lower door beam 66. The upper door beam 62 and the lower door beam 66 are respectively fixed to the upper fixed beam 10 and the lower fixed beam 12 in the main frame 5. A left door panel 61 and a right door panel 63 are arranged side by side between the upper door beam 62 and the lower door beam 66. Door shafts 64 are provided at the ends of the upper door beam 62 and the lower door beam 66. The right door panel 63 is hinged to the upper door beam 62 and the lower door beam 66 through the corresponding upper and lower door shafts 64. Magnetic door catches 69 corresponding to the left door panel 61 and the right door panel 63 are respectively provided on the inner sides of the upper door beam 62 and the lower door beam 66. A safety induction block 67 is also fixed on the upper door beam 62.

[0065] At the docking position of the left door panel 61 and the right door panel 63, the left door panel 61 and the right door panel 63 are hinged through a plurality of hinges 68 arranged from top to bottom. A door handle 65 is provided on the side of the left door panel 61. The right door panel 63 can be driven to open and close and the left door panel 61 and the right door panel 63 can be folded through the door handle 65.

[0066] The above-mentioned human-machine interface 2 is hinged to the right door panel 63 through a screen rotating shaft 70 at its top. When the left door panel 61 and the right door panel 63 are opened and folded, the human-machine interface 2 can be rotated through the screen rotating shaft 70 to realize multi-angle display and control.

[0067] The specific working process and working principle are as follows:

[0068] First, according to the size of the glass bottle to be inspected, the height of the belt bottle conveying mechanism 8 and the distance between two belt bottle conveying units are adjusted through the belt adjusting mechanism 9, and the distance between the upper belt 42 and the lower belt 44 inside it is adjusted through the belt height adjusting push rod 38. The glass bottle enters this inspection machine through the bottle inlet chain plate 50 in the chain plate bottle conveying mechanism 4.

[0069] After entering the interior of this inspection machine, it is conveyed by the belt bottle conveying mechanism 8. At this time, the upper belt 42 and the lower belt 44 in the two belt bottle conveying units respectively clamp on both sides of the glass bottle, driving the glass bottle to move inside this inspection machine. When the glass bottle moves below the shooting mechanism 6, it first passes through the opposed sensing component 19 and triggers it. After the opposed sensing component 19 is triggered, a trigger signal is sent into the electrical cabinet 1. The control circuit in the electrical cabinet 1 controls the reflective bottle mouth detection device 20, the incident bottle mouth detection device 21, and the bottle bottom detection device 22 to sequentially take pictures of the glass bottle according to the moving speed and distance of the glass bottle and the calculated time.

[0070] The reflective bottle mouth detection device 20, the incident bottle mouth detection device 21, and the bottle bottom detection device 22 send the taken images into the electrical cabinet 1. The control circuit in the electrical cabinet 1 combines with the software part to judge the defects of the glass bottle, and then the glass bottle is transferred to the bottle outlet chain plate 55 in the chain plate bottle conveying mechanism 4 by the belt bottle conveying mechanism 8 again and transferred out of this inspection machine.

[0071] When the glass bottles move on the chain plate bottle conveying mechanism 4, they are counted by the counting sensors 51 at the bottle inlet chain plate 50 and the bottle outlet chain plate 55 respectively. After the glass bottles are transferred out of this inspection machine, the defective glass bottles are removed by the subsequent bottle rejection mechanism.

[0072] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution content of the present invention still fall within the protection scope of the technical solution of the present invention.
