[0040] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0041] like Figures 1-17As shown, the specific structure of the present invention is:

[0042] A row of plastic ampoule bottle inspection machines, which includes a conveyor mesh 1 arranged on a frame 2, and the side edges of the conveyor mesh 1 are sequentially provided with a bottle separation and pressing device 3, a camera detection device 5, and a waste rejection device 12 along the conveying direction; at least one camera detection device 5 is distributed on each side of the conveyor mesh 1, and each camera detection device 5 is equipped with a corresponding light source 6; each of the camera detection devices 5 is provided with two cameras 58 for detecting the head and bottle body of the ampoule bottle 13 respectively; the waste rejection device 12 is connected to a waste rejection plate 127 located on the side of the conveyor mesh 1 for pushing out waste products by a linear reciprocating mechanism; the bottle separation and pressing device 3 is connected to a pressure block 37 located on the side of the conveyor mesh 1 for pressing the ampoule bottle 13 by a linear reciprocating mechanism.

[0043] Further optimization based on the above embodiment:

[0044] like Figure 1 As shown, in order to accurately activate the camera detection device 5 when the ampoule bottle 13 passes through the camera detection station, multiple sensor switches 4 are installed on the side of the conveyor belt 1 for sensing the position of the ampoule bottle 13. The sensor switches 4 are installed on the side of the conveyor belt 1 and can be photoelectric sensors; the sensor switches 4 are installed in front of the corresponding camera detection device 5.

[0045] like Figure 1-2 As shown, in order to prevent the ampoule bottle 13 from falling over on both sides when moving on the conveyor mesh belt 1, baffles 14 for preventing the ampoule bottle 13 from falling are provided on both sides above the conveyor mesh belt 1. On the side of the rejecting device 12, the baffle 14 is replaced by a movable baffle 134.

[0046] like Figure 4-7 As shown, the bottle-separating and pressing device 3 includes a bottle-separating base 31 mounted on the frame 2 and located on the side of the conveyor belt 1. A bottle-separating motor 32 is mounted on the bottle-separating base 31; a bottle-separating turntable 36 is mounted on the motor shaft of the bottle-separating motor 32; a bottle-separating slide rail 39 is mounted on the bottle-separating slide rail 39; a bottle-separating slider 40 is mounted on the bottle-separating slide rail 39; the bottle-separating slider 40 is hingedly connected to the eccentric position of the bottle-separating turntable 36 via a bottle-separating connecting rod 38; and a pressing block 37 is mounted on the bottle-separating slider 40.

[0047] A bottle-separating motor seat 33 is installed on the bottle-separating base 31; the bottle-separating motor 32 is installed on the bottle-separating motor seat 33; a bottle-separating photoelectric sensor 34 is also installed on the bottle-separating motor seat 33 and is located on the side of the motor shaft; a bottle-separating light shield 35 for cooperating with the bottle-separating photoelectric sensor 34 is installed on the side of the bottle-separating turntable 36.

[0048] The bottle separation motor 32 rotates, driving the bottle separation turntable 36 to rotate. The bottle separation turntable 36 drives the bottle separation slider 40 to slide back and forth on the bottle separation slide rail 39 through the bottle separation connecting rod 38. A pressure block 37 is installed on the front end of the bottle separation slider 40 through a bolt. The pressure block 37 moves telescopically to press the ampoule bottle 13 moving on the conveyor belt 1, causing the ampoule bottle 13 to temporarily move until the front ampoule bottle 13 has moved a certain distance.

[0049] like Figure 8-11 As shown, the camera detection device 5 includes a fixing frame 51 installed on the frame 2 and located on the side of the conveyor belt 1; camera mounting rods 57 are installed at the upper and lower positions of the side of the fixing frame 51; and a camera 58 is installed on the camera mounting rod 57.

[0050] An adjustment frame 52 that can be moved up and down to adjust its position is fixed to the fixing frame 51 by bolts; a horizontal cross plate 60 is provided on the side wall of the adjustment frame 52 in the vertical direction; a mounting hole and an arc groove 56 are provided on the fixing frame 51 and are located below or above the cross plate 60; the mounting hole and the arc groove 56 are cocentric; a screw 572 and a pin 571 are provided at the tail end of the camera mounting rod 57; the screw 572 passes through the mounting hole, the thrust bearing 59, and the adjustment disk 55 in sequence and is connected and fixed with a nut; the pin 571 passes through the arc groove 56 and is inserted into the pin hole on the adjustment disk 55; an adjusting screw 53 is threaded on the cross plate 60; the end of the adjusting screw 53 presses against the clamping block 54; the clamping block 54 presses against the side wall of the adjustment disk 55; the contact surface between the clamping block 54 and the adjustment disk 55 is a matching arc surface.

[0051] The fixing frame 51 is provided with long waist-shaped holes on both sides; the adjusting frame 52 is connected and fixed to the waist-shaped holes by bolts.

[0052] Since row-up plastic ampoules come in different sizes and heights, the camera's height and tilt angle must be adjusted when inspecting ampoules of different heights. Improper angle adjustment can easily lead to reflections and incomplete images. Traditional camera mounts are generally fixed, making adjustment inconvenient.

[0053] In the camera detection device 5 of the present invention, it is only necessary to manually loosen the adjustment screw 53 to release the resistance of the clamping block 54 to the adjustment disk 55. The staff can easily adjust the tilt angle of the camera by slightly rotating the adjustment disk 55 to achieve fine-tuning of the detection of ampoules of different heights.

[0054] The height of the adjusting frame 52 can be adjusted by the staff after loosening the connecting bolts between the adjusting frame 52 and the fixing frame 51 .

[0055] The outer side wall of the adjustment disk 55 may be provided with anti-skid patterns, and the contact surface between the pressing block 54 and the adjustment disk 55 may also be provided with anti-skid patterns to increase resistance.

[0056] like Figure 12-17 As shown, the waste rejection device 12 includes a waste rejection base 121 installed on the frame 2 and located on the side of the conveyor belt 1, a waste rejection motor 122 is installed on the waste rejection base 121; a waste rejection turntable 126 is installed on the motor shaft of the waste rejection motor 122; a waste rejection slide rail 129 is installed on the waste rejection slide rail 129; the waste rejection slider 130 is hinged to the eccentric position of the waste rejection turntable 126 through a waste rejection connecting rod 128; the waste rejection slider 130 is connected to the eccentric position of the waste rejection turntable 126 through a waste rejection connecting rod 128; the waste rejection slider 1 30 is equipped with a waste rejection plate 127; the waste rejection plate 127 is arranged toward the conveyor mesh belt 1; a toggle block 132 is vertically arranged above the waste rejection plate 127; a movable blocking rod 134 is arranged on the side above the conveyor mesh belt 1; both ends of the movable blocking rod 134 are connected to the front end of the U-shaped rod 133; the top ends of the two U-shaped rods 133 are hinged on the corresponding vertical rods on the frame 2; the tail ends of the two U-shaped rods 133 are connected to each other through a connecting plate 135; the connecting plate 135 is located in front of the toggle block 132.

[0057] A waste rejection motor base 123 is installed on the waste rejection base 121; the waste rejection motor 122 is installed on the waste rejection motor base 123; the waste rejection motor base 123 is also equipped with a waste rejection photoelectric sensor 124 located on the side of the motor shaft; a waste rejection light blocking piece 125 for cooperating with the waste rejection photoelectric sensor 124 is installed on the side of the waste rejection turntable 126.

[0058] The rejection motor 122 rotates, driving the rejection turntable 126 to rotate. The rejection turntable 126 drives the rejection slider 130 to slide back and forth on the rejection slide rail 129 through the rejection connecting rod 128. The front end of the rejection slider 130 is installed with a rejection plate 127 by bolts. The rejection plate 127 moves forward, and the toggle block 132 vertically installed above the rejection plate 127 pushes the U-shaped rod 133 to flip, and the movable blocking rod 134 on the other side of the U-shaped rod 133 flips upward, so that the other side of the conveyor mesh belt 1 loses its limit. At this time, the rejection plate 127 continues to move forward and pushes the ampoule bottle 13 on the conveyor mesh belt 1, causing the ampoule bottle 13 to tilt outward and fall into the waste hopper 9.

[0059] The specific working principle of the present invention is:

[0060] The row of ampoule bottles enters the conveyor belt 1, and the pressing block 37 of the bottle separation and pressing device 3 is reciprocated and released to separate the ampoule bottles 13 at a certain interval. Then, after being sensed by the sensor switch 4, the camera station of the front camera detection device 5 is triggered to take a picture, and then the ampoule bottles 13 continue to move forward, triggering the next sensor switch 4, so that the camera of the rear camera detection device 5 takes a picture. When taking pictures, the corresponding light source 6 is turned on, so that the best detection effect can be achieved. Each camera station is installed with two or more cameras. The two cameras respectively take pictures of the bottle head and bottom to determine whether the bottle has defects. When the defective bottle passes through the rejection device 12 station, the rejection plate 127 at the front end of the rejection device 12 moves forward to reject the waste from the conveyor belt 1. The qualified row of ampoule bottles goes straight along the mesh belt to enter the next process or be collected.

[0061] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements that are inherent to such process, method, article or apparatus.

[0062] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method of the present invention and its core ideas. The above is only a preferred implementation method of the present invention. It should be pointed out that due to the limitations of textual expression, there are objectively infinite specific structures. For ordinary technicians in this technical field, without departing from the principles of the present invention, they can make several improvements, modifications or changes, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the inventive concept and technical solution to other occasions without improvement, should be regarded as the scope of protection of the present invention.
