The tops of the left and rear frames 9 are installed with electric push rods 122. The telescopic rods of the two electric push rods 122 are respectively connected to the two L-shaped pushing blocks 121.

[0033] See also Figure 4-Figure 6The lifting mechanism includes a spline shaft 111 key-connected in the hollow rotating shaft 5, the top end of the spline shaft 111 extends into the positioning sleeve 6 and is connected to a lifting block 115, the bottom end of the spline shaft 111 is connected to a contact ball 112, a spring Ⅰ114 is connected between the contact ball 112 and the hollow rotating shaft 5, and the left and rear sides of the inner bottom of the annular mounting seat 2 are connected to trapezoidal blocks 113, the two trapezoidal blocks 113 correspond to the belt conveyor 10 on the left and rear sides respectively, and the contact ball 112 can contact the trapezoidal block 113 as the mounting ring 42 rotates.

[0034] The low-borosilicate glass controlled injection bottle to be inspected is placed into the positioning sleeve 6 manually or by using a robot. The stepper motor 3 can drive the ring frame 4 to rotate, so that the positioning sleeve 6 can rotate to transport the low-borosilicate glass controlled injection bottle to be inspected to align with the photographing scanner 8. The contact ball 112 follows the rotation of the mounting ring 42 and can contact the trapezoidal block 113. Under the push of the inclined surface on the trapezoidal block 113, the contact ball 112 drives the spline shaft 111 to move upward, and the spring I 114 is compressed accordingly. The spline shaft 111 moves upward and pushes the top block 115 to move upward to push the low-borosilicate glass controlled injection bottle out of the positioning sleeve 6, so as to achieve the effect of lifting the low-borosilicate glass controlled injection bottle from the positioning sleeve 6 for inspection, ensuring that the low-borosilicate glass controlled injection bottle is not blocked by the positioning sleeve 6, thereby achieving comprehensive and accurate inspection of the low-borosilicate glass controlled injection bottle, thereby improving the accuracy of selecting defective low-borosilicate glass controlled injection bottles. After the low-borosilicate glass controlled injection bottle is lifted from the positioning sleeve 6, the servo motor 134 is controlled to drive the small pulley 135 to rotate, thereby driving the large pulley 131 to rotate through the flat belt 136, and the inner gear ring 132 rotates accordingly. Through the cooperation of the inner gear ring 132 and the gear I 133, the hollow shaft 5 can be driven to drive the positioning sleeve 6 and the spline shaft 111 to rotate, so that the top block 115 can drive the low-borosilicate glass controlled injection bottle to rotate, ensuring that the outer wall of the low-borosilicate glass controlled injection bottle is evenly photographed and scanned by the photographing scanner 8. When the photographing scanner 8 detects When it is detected that the outer wall of the low-borosilicate glass controlled injection bottle has cracks and defects and is an unqualified defective product, the shooting scanner 8 sends a signal to the controller. After receiving the signal, the controller sends a command to control the telescopic rod of the left electric push rod 122 to retract first and then extend, so that the L-shaped push block 121 on the left reciprocates left and right. The L-shaped push block 121 on the left moves to the left to push the unqualified low-borosilicate glass controlled injection bottle to the left and onto the belt conveyor 10 on the left. The unqualified low-borosilicate glass controlled injection bottle is transported to the left through the belt conveyor 10 on the left.If the inspected low-borosilicate glass controlled injection bottle is qualified, the left electric push rod 122 will not be started. When the contact ball 112 rotates with the mounting ring 42 to disengage from the trapezoidal block 113, under the reset action of the spring I 114, the contact ball 112 pulls the top block 115 downward and resets through the spline shaft 111, so that the qualified low-borosilicate glass controlled injection bottle moves down and enters the positioning sleeve 6. The qualified low-borosilicate glass controlled injection bottle is then rotated and transported to align with the rear belt conveyor 10, and the rear electric push rod 122 drives the rear L-shaped push block 121 to move back and forth backward and forward. The rear L-shaped push block 121 moves backward to push the qualified low-borosilicate glass controlled injection bottle backward to the rear belt conveyor 10, and the qualified low-borosilicate glass controlled injection bottle is pushed to the rear belt conveyor 10 through the rear belt conveyor 10. After the conveying, the qualified low-borosilicate glass controlled injection bottles are sorted from the defective ones. Since the two trapezoidal blocks 113 correspond to the belt conveyors 10 on the left and rear sides respectively, after the qualified low-borosilicate glass controlled injection bottles are rotated and transported to align with the belt conveyor 10 on the rear side, the qualified low-borosilicate glass controlled injection bottles have been pushed upward from the positioning sleeve 6 by the push block 115, and the qualified low-borosilicate glass controlled injection bottles will not be blocked by the positioning sleeve 6, and can be smoothly pushed backwards to the rear belt conveyor 10 by the rear L-shaped push block 121; in this way, the device can automatically separate the qualified low-borosilicate glass controlled injection bottles, without the need for subsequent manual screening of the qualified and defective low-borosilicate glass controlled injection bottles, thereby saving time and effort, and greatly improving the sorting efficiency of qualified and defective low-borosilicate glass controlled injection bottles.

[0035] See also Figure 7-Figure 9, a limiting mechanism for pressing and fixing the bottle on the top block 115 is provided on the mounting ring 42, and the limiting mechanism includes a guide rail 141 and a lifting plate I 142. Eight guide rails 141 are connected to the inner wall of the mounting ring 42 at uniform intervals along the circumferential direction. The eight guide rails 141 are located on the inner side of the eight positioning sleeves 6. The eight guide rails 141 correspond to the eight positioning sleeves 6 one by one. A lifting plate I 142 is slidably connected in the guide rail 141, and a spring II 140 is connected between the lifting plate I 142 and the guide rail 141. A sliding rod 143 is slidably connected to the side of the lifting plate I 142 away from the guide rail 141, and a pressing block 144 is rotatably connected to the bottom end of the sliding rod 143. The eight pressing blocks 144 correspond to the eight positioning sleeves 6 one by one, and the pressing blocks 144 are located above the corresponding positioning sleeves 6. A spring III 145 is connected between the sliding rod 143 and the lifting plate I 142. A pushing plate 1142 is provided on the guide rail 141 for pushing the lifting plate I 142 downward. The driving assembly includes a gear II 146 rotatably connected to the outer wall of the guide rail 141, a lifting plate II 147 is slidably connected in the guide rail 141, and the lifting plate II 147 is located below the lifting plate I 142. A rack I 148 is connected to the side of the lifting plate I 142 away from the slide bar 143, and a rack II 149 is connected to the lifting plate II 147. The rack I 148 and the rack II 149 are both meshed with the gear II 146. The eight contact balls 112 The eight round blocks 1410 correspond to the eight lifting plates II 147 one by one. The round blocks 1410 are located at the lower side of the corresponding lifting plates II 147. The round blocks 1410 are in contact with the corresponding lifting plates II 147. The L-shaped push block 121 is provided with a receiving groove 120 for accommodating the guide rail 141. The circumferential side wall of the pressing block 144 is an arc surface. The L-shaped push block 121 is provided with an inclined surface 15 that matches the arc surface on the pressing block 144.

[0036] When the contact ball 112 pushes the spline shaft 111 and the ejector block 115 upward to eject the low-borosilicate glass controlled injection bottle from the positioning sleeve 6, the contact ball 112 also drives the round block 1410 upward, thereby pushing the lifting plate Ⅱ147 through the round block 1410 to drive the rack Ⅱ149 upward, and the upward movement of the rack Ⅱ149 drives the gear Ⅱ146 to rotate to push the rack Ⅰ148 and the lifting plate Ⅰ142 to move downward, and the spring Ⅱ140 is compressed accordingly, so that the pressing block 144 moves downward to press and fix the low-borosilicate glass controlled injection bottle on the ejector block 115, so as to prevent the low-borosilicate glass controlled injection bottle from falling off the ejector block 115 when it is lifted from the positioning sleeve 6 for rotation detection, thereby improving stability and safety, and ensuring that the low-borosilicate glass controlled injection bottle is effectively detected. After the pressing block 144 moves downward and contacts the top of the low-borosilicate glass controlled injection bottle, it cannot move further downward, and the sliding rod 143 is subsequently held up and cannot move further downward, so that the lifting plate I 142 continues to move downward to compress the spring III 145, so that it can adapt to low-borosilicate glass controlled injection bottles of different heights to avoid crushing the low-borosilicate glass controlled injection bottles; when the L-shaped pushing block 121 moves to push the low-borosilicate glass controlled injection bottle onto the belt conveyor 10, the inclined surface 15 on the L-shaped pushing block 121 first contacts the arc surface on the pressing block 144, thereby first pushing the pressing block 144 to move upward and disengage from the low-borosilicate glass controlled injection bottle to release the limit on the low-borosilicate glass controlled injection bottle, and then the L-shaped pushing block 121 continues to move to smoothly push the low-borosilicate glass controlled injection bottle onto the belt conveyor 10, thereby avoiding damage to the low-borosilicate glass controlled injection bottle. When the contact ball 112 is separated from the trapezoidal block 113 and moves downward to reset, the round block 1410 moves downward to reset and releases the lifting plate II 147. Under the reset action of the spring II 140, the lifting plate I 142 drives the slide bar 143, the pressure block 144, the spring III 145 and the rack I 148 to move upward and reset. The rack I 148 moves upward to drive the gear II 146 to reverse and push the rack II 149 to move the lifting plate II 147 downward and reset.

[0037] See also Figure 7An arc-shaped brush 16 is connected to the top front side of the annular mounting seat 2. The low-borosilicate glass controlled injection bottle that needs to be inspected and sorted contacts the arc-shaped brush 16 during the process of rotating with the mounting ring 42 to align with the photographing scanner 8. The arc-shaped brush 16 can clean the low-borosilicate glass controlled injection bottle that needs to be inspected and sorted, and through the cooperation of the gear Ⅰ133 and the inner gear ring 132, the hollow rotating shaft 5 can drive the positioning sleeve 6 to rotate, and the rotation of the positioning sleeve 6 drives the low-borosilicate glass controlled injection bottle to rotate, ensuring that the low-borosilicate glass controlled injection bottle is fully cleaned. In this way, the device can clean the low-borosilicate glass controlled injection bottle before inspection and sorting to remove impurities on the outer wall of the low-borosilicate glass controlled injection bottle that may affect the detection accuracy, thereby further improving the detection accuracy, and further improving the accuracy of selecting defective low-borosilicate glass controlled injection bottles.

[0038] See also Fig. 9 Two connecting rods 17 are symmetrically connected on one side of the L-shaped push block 121 close to the inclined surface 15 with the accommodating groove 120 as the center, and a buffer pad 18 is connected to the outer wall of the connecting rod 17. The buffer pad 18 can prevent the L-shaped push block 121 from directly colliding with the low-borosilicate glass controlled injection bottle, thereby protecting the low-borosilicate glass controlled injection bottle.

[0039] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
