Description

Technical Field

[0001] This application relates to the field of testing technology, and more specifically, to a rapid testing device for variable diameter glass bottles. Background Technology

[0002] Glass bottles are a widely used type of glass product, such as beer bottles, rice wine bottles, vinegar bottles, and beverage bottles. Currently, due to the requirement for lightweight glass bottles, the wall thickness of glass bottles is becoming thinner and thinner. At the same time, there are also high requirements for the uniformity of the glass bottle wall thickness. Glass bottles with large differences in wall thickness cannot be allowed to enter the market. Therefore, the wall thickness of glass bottles needs to be tested during the glass bottle production process.

[0003] Chinese patent application CN114608459B discloses a glass tube inspection device, relating to the technical field of inspection. The device includes a workbench equipped with a wall thickness detection device and a defect detection device. The wall thickness detection device comprises at least one set of detection mechanisms and an adjustment mechanism for adjusting the position of these mechanisms. The detection mechanisms are used to detect the wall thickness of the glass tube, and the defect detection device is used to detect whether there are defects in the tube wall. While the aforementioned application can detect the thickness of glass tubes of different specifications by adjusting the position of the detection mechanisms, it is inconvenient for inspecting variable-diameter glass bottles, requiring manual adjustment of the detection mechanism's position, which leads to low inspection efficiency. Summary of the Invention

[0004] This invention addresses the problem that while existing technologies can check the thickness of glass tubes of different specifications by adjusting the position of the detection mechanism, this is inconvenient for detecting variable-diameter glass bottles, requiring manual adjustment of the detection mechanism and resulting in low detection efficiency. Therefore, this invention proposes a rapid detection device for variable-diameter glass bottles, which can adapt to the variable-diameter bottle shape, thus improving detection efficiency.

[0005] To achieve the above objectives, this application provides a rapid detection device for variable-diameter glass bottles, including a base. Two elastic grippers for holding glass bottles are symmetrically mounted on the upper surface of the base. An intermittent toothed rod is fixed on the upper surface of the base. A track rod is fixed between the two elastic grippers. A detection device is slidably mounted on the track rod. A first electric telescopic rod for controlling the movement of the detection device is fixed on the base.

[0006] The detection equipment includes:

[0007] A slider is slidably connected to the track rod, an annular block is fixed on the slider, a double gear transmission box is fixed on the side of the annular block, and three sets of laser thickness detection components arranged in an annular array are slidably connected through the interior of the annular block.

[0008] A rotating annular block is rotatably connected to the side of the annular block. An arc-shaped spring is fixed between the rotating annular block and the annular block. Three track blocks arranged in a circular array are fixed to the outside of the rotating annular block. A toothed assembly is fixed to the outside of the rotating annular block.

[0009] Preferably, the track block is an inclined arc-shaped block structure, and a groove is provided at the front end of the track block near the laser thickness detection component.

[0010] Preferably, the two gears of the dual-gear transmission box mesh with the toothed gear assembly and the intermittent toothed gear rod, respectively.

[0011] Preferably, the laser thickness detection component includes a first support block and a second support block. The first support block is slidably connected to the inside of the annular block. Four positioning rods for connecting the second support block are fixed to the top of the first support block. The second support block is slidably connected to the four positioning rods. A small spring is fixed between the second support block and the first support block. A cylindrical rod is fixed to the side of the second support block and slidably connected to a groove in the track block. A laser sensing head is fixed inside the first support block, and a roller is rotatably connected to the bottom of the first support block. During the detection process, the roller inside the laser thickness detection component moves against the glass bottle body under the sliding action of the track block, and the thickness is detected by the laser sensing head.

[0012] Preferably, there is a height difference between the laser sensing head and the roller, with the roller being closer to the center of the annular block relative to the laser sensing head. Since the roller needs to fit snugly against the glass bottle, a height difference between the roller and the laser sensing head is necessary to ensure that the laser sensing head does not touch the glass bottle.

[0013] Preferably, the upper surface of the base is equipped with a unloading assembly, which includes a second electric telescopic rod. Two C-shaped locking blocks are fixed to the extended end of the second electric telescopic rod. A unloading bracket is slidably connected between the two C-shaped locking blocks. Two symmetrically arranged clamping rods are rotatably connected to the unloading bracket. A three-way hydraulic pipe is fixed inside the unloading bracket. A liquid storage bladder is fixed to one end of the three-way hydraulic pipe, and hydraulic rods are slidably connected to the other two ports of the three-way hydraulic pipe. The two hydraulic rods are respectively fixed to the two clamping rods. After the inspection is completed, the unloading assembly is used to remove the glass bottle from the two elastic clamps, facilitating the removal of the glass bottle by the staff.

[0014] Preferably, the liquid storage bladder is located at the front end of the extension of the second electric telescopic rod, and a sponge pad is fixed inside both hydraulic rods. The sponge pad prevents excessive clamping force and avoids clamping damage to the glass bottle.

[0015] The advantages of this application are:

[0016] (1) This application uses a detection device that can move laterally to detect the thickness of the glass bottle body area. At the same time, it uses a laser thickness detection component that can adapt to the height of the bottle body to detect the thickness of the three areas of the bottle body in sequence. This solves the problem that the existing technology requires manual adjustment when detecting variable diameter glass bottles, and greatly improves the detection efficiency.

[0017] (2) By setting up a discharge assembly, the glass bottles after the test can be removed from the two elastic clamps, making it convenient for staff to collect the glass bottles.

[0018] (3) By setting a sponge pad inside the hydraulic rod, this application can prevent excessive clamping force from causing clamping damage to the glass bottle during the unloading process. Attached Figure Description

[0044] Example 1

[0045] See Figures 1-9 as well as Figure 13This embodiment provides a rapid detection device for variable-diameter glass bottles, including a base 100. Two elastic grippers 200 for holding glass bottles are symmetrically mounted on the upper surface of the base 100. The two elastic grippers 200 respectively hold the edges of regions A and C of the glass bottle. An intermittent toothed rod 500 is fixed on the upper surface of the base 100. The teeth on the intermittent toothed rod 500 are divided into three segments. The number of teeth in the first segment is the same as the number of teeth in the third segment, and the number of teeth in the first segment and the third segment is half the number of teeth in the second segment. A certain distance is left between the teeth in the second segment and the third segment. A track rod 300 is fixed between the two elastic grippers 200. A detection device 600 is slidably mounted on the track rod 300. A first electric telescopic rod 400 for controlling the movement of the detection device 600 is fixed on the base 100.

[0046] The detection device 600 includes:

[0047] A slider 610 is slidably connected to the track rod 300. There are two track rods 300, which can make the slider 610 slide very smoothly. An annular block 620 is fixed on the slider 610. A double gear transmission box 650 is fixed on the side of the annular block 620. Three sets of laser thickness detection components 680 arranged in a ring array are slidably connected through the interior of the annular block 620.

[0048] A rotating annular block 630 is rotatably connected to the side of the annular block 620. An arc-shaped spring 640 is fixed between the rotating annular block 630 and the annular block 620. Three track blocks 670 arranged in a ring array are fixed on the outer side of the rotating annular block 630. The track blocks 670 are inclined arc-shaped block structures, and a sliding groove is opened at the front end of the track blocks 670 near the laser thickness detection component 680. A toothed assembly 660 is fixed on the outer side of the rotating annular block 630. The two gears of the dual gear transmission box 650 mesh with the toothed assembly 660 and the intermittent toothed rod 500, respectively.

[0049] The laser thickness detection component 680 includes a first support block 681 and a second support block 682. The first support block 681 is slidably connected to the inside of the annular block 620. Four positioning slide rods 683 for connecting the second support block 682 are fixed to the top of the first support block 681. The second support block 682 is slidably connected to the four positioning slide rods 683. A small spring 684 is fixed between the second support block 682 and the first support block 681. The supporting force of the small spring 684 is greater than the weight of the second support block 682. A cylindrical rod 685 is fixed to the side of the second support block 682. The cylindrical rod 685 is slidably connected to the groove of the track block 670. When the track block 670 rotates, the cylindrical rod 685 slides within the groove of the track block 670. The track block 670 has an inclined structure, which will exert a squeezing effect on the cylindrical rod 685, thereby squeezing the second support block 682 and the first support block 681 to move. A laser sensing head 686 is fixed inside the first support block 681. The thickness of the glass bottle is detected by the laser sensing head 686, and the thickness of the glass bottle is judged by the feedback data. A roller 687 is rotatably connected to the bottom of the first support block 681. There is a height difference between the laser sensing head 686 and the roller 687. The roller 687 is closer to the center area of ​​the annular block 620 than the laser sensing head 686. Since the roller 687 needs to fit in close contact with the glass bottle, there is a height difference between the roller 687 and the laser sensing head 686 to ensure that the laser sensing head 686 does not touch the glass bottle.

[0050] By setting up a detection device 600 that can move laterally to detect the thickness compliance of the glass bottle body area, and at the same time using a laser thickness detection component 680 that can adapt to the height of the bottle body to sequentially detect the thickness of the three areas of the bottle body, the problem of manual adjustment required for the detection of variable diameter glass bottles in the existing technology is solved, and the detection efficiency is greatly improved.

[0051] When using the above equipment, first connect area A and area C of the glass bottle (see details). Figure 13The slider 610 is held in place by two elastic clamps 200. When the first electric telescopic rod 400 is activated, it pushes the slider 610 to slide on the two track rods 300. As the slider 610 slides, the annular block 620 follows suit. At this point, the first gear in the dual-gear transmission box 650 contacts the first section of teeth on the intermittent toothed rod 500, causing the first gear in the dual-gear transmission box 650 to rotate. This, in turn, drives the second gear in the dual-gear transmission box 650 to rotate, which in turn engages with the toothed assembly on the annular rotating block 630. When 660 rotates, it causes the annular rotating block 630 to rotate. At this time, the three track blocks 670 fixed on the annular rotating block 630 will rotate accordingly. When the track blocks 670 rotate, the cylindrical rod 685 will slide within the groove of the track block 670. Because the track block 670 has an inclined structure, it will exert a squeezing effect on the cylindrical rod 685, thereby squeezing the second support block 682 towards the center of the annular block 620. As the second support block 682 moves, under the action of the four small springs 684, it pushes the first support block 681 towards the annular block 620. As the slider 610 moves in the direction of its center, the movement of the first support block 681 pushes the roller 687 to contact area A of the glass bottle body. Thickness is then detected by the laser sensor 686. Since the dual gear transmission box 650 continuously meshes with the first section of teeth on the intermittent locking pin 500, the second support block 682 continues to move downwards. At this point, the second support block 682, under the action of the small spring 684 and the positioning slide rod 683, approaches the first support block 681, achieving a retraction effect. As the slider 610 moves, the dual gear transmission box 650 temporarily engages with the intermittent locking pin 500. The first tooth in the rack 500 separates and quickly contacts the second tooth. At this time, the first support block 681 in the retracted state will extend under the rebound force of the small spring 684. At this time, the laser thickness detection component 680 is located in area B of the glass bottle. After the dual gear transmission box 650 contacts the second tooth on the intermittent rack 500, the above steps are repeated. The first support block 681 will drive the laser sensing head 686 to move down continuously until the roller 687 contacts area B of the glass bottle. Then, the thickness of area B of the glass bottle is detected by the laser sensing head 686.

[0052] When the annular rotating block 630 rotates, it will compress the arc spring 640;

[0053] As the slider 610 continues to move, the dual gear transmission box 650 contacts the blank area of ​​the intermittent toothed rod 500. At this time, the annular block 620 and the annular rotating block 630 are reset under the action of the rebound force of the arc spring 640. As the slider 610 continues to move, the detection device 600 is located in region C of the glass bottle. The above operation is repeated to detect the thickness of region C of the glass bottle.

[0054] See Figure 1 , Figure 2 , Figure 10 , Figure 11 , Figure 12 , Figure 13 The upper surface of the base 100 is equipped with a discharge assembly 700, which includes a second electric telescopic rod 710. A trigger switch is provided on the side of the second electric telescopic rod 710 near the first electric telescopic rod 400. Two C-shaped locking blocks 730 are fixed on the extended end of the second electric telescopic rod 710. A discharge bracket 720 is slidably connected between the two C-shaped locking blocks 730. Two symmetrically arranged clamping rods 740 are rotatably connected to the discharge bracket 720. A T-junction is fixed inside the discharge bracket 720. The three-way hydraulic pipe 750 has a liquid storage bladder 770 fixed at one end. The other two ports of the three-way hydraulic pipe 750 are piston-slidably connected to hydraulic rods 760. The two hydraulic rods 760 are respectively fixed to the two clamping rods 740. The liquid storage bladder 770 is located at the front end of the extension end of the second electric telescopic rod 710. The two hydraulic rods 760 are each fixed with a sponge pad 780. The sponge pad 780 can prevent excessive clamping force and avoid clamping damage to the glass bottle.

[0055] In practical use, after the inspection is completed, as the first electric telescopic rod 400 extends, when the inspection of area C of the glass bottle is finished, the trigger switch of the second electric telescopic rod 710 will be triggered, causing the extended end of the second electric telescopic rod 710 to extend. First, the extended end of the second electric telescopic rod 710 will squeeze the liquid storage bladder 770, and push the unloading bracket 720 to move through the C-shaped locking block 730, squeezing the liquid in the liquid storage bladder 770 into the three-way hydraulic pipe 750, causing the two hydraulic rods 760 to push the two clamping rods 740 to rotate and clamp the glass bottle. Then, the glass bottle is removed by pushing the second electric telescopic rod 710. Then, when the second electric telescopic rod 710 slowly resets, the unloading bracket 720 contacts the other end of the C-shaped locking block 730, causing the second electric telescopic rod 710 to separate from the liquid storage bladder 770, and the two clamping rods 740 to reset. When the second electric telescopic rod 710 resets, the glass bottle can be removed by the operator.

[0056] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
