Description

Technical Field

[0001] This utility model relates to the field of dropper processing technology, specifically to a dropper testing line. Background Technology

[0002] like Figure 1 The dropper shown has a constricted end at one end and a rubber bulb at the other end for measuring liquid by the number of drops. Therefore, the appearance and size of its end (especially the constricted end) are key to determining whether the dropper product is qualified. For this reason, it is necessary to inspect the appearance of the dropper end through testing equipment during the dropper manufacturing process. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a dropper inspection line, which can be used for appearance inspection of the dropper ends during mass production of droppers.

[0004] The technical solution is as follows: a dropper testing line includes a conveying device, a feeding device, and a testing device. The feeding device is used to place the processed droppers on the conveying device. The conveying device is used to transport the droppers to the testing device. The testing device includes a mounting frame, a light source, and an appearance inspection device. The testing device further includes a dropper lifting mechanism and a dropper rotating mechanism. The light source, the appearance inspection device, and the dropper rotating mechanism are mounted above the conveying device via the mounting frame. The dropper rotating mechanism is located between the light source and the appearance inspection device. The dropper lifting mechanism is located below the dropper rotating mechanism. The dropper lifting mechanism is used to lift the droppers on the conveying device to the dropper rotating mechanism and suspend both ends of the droppers. The dropper rotating mechanism includes a drive wheel, which can contact the lifted dropper and drive it to rotate.

[0005] Furthermore, the conveying device includes at least two sets of conveying chains, each set of conveying chains is uniformly equipped with conveying blocks, the two ends of the dropper are respectively placed in the V-shaped grooves recessed in the middle of the conveying blocks, and the dropper lifting mechanism is located in the middle of the two sets of conveying chains.

[0006] Furthermore, the dropper lifting mechanism includes a vertical sliding mechanism and a lifting slider. The lifting slider is mounted on the vertical sliding mechanism and can be driven by the vertical sliding mechanism to move up and down. The top of the lifting slider is set corresponding to the middle of the dropper and can pass between the two sets of conveying chains to be lifted to the drive wheel.

[0007] Furthermore, the dropper rotation mechanism includes a first mounting base, an adjusting slider, and a drive motor. The first mounting base is fixedly connected to the mounting frame, the adjusting slider is slidably connected to the first mounting base via an adjusting screw, the drive motor is mounted on the bottom of the adjusting slider, and the output end of the drive motor is connected to the drive wheel.

[0008] Furthermore, the feeding device includes a gantry frame, feeding grippers, and a feeding buffer mechanism. The feeding grippers are mounted on the gantry frame and are used to transfer the processed droppers to the feeding buffer mechanism. The feeding buffer mechanism is located above the conveying device and includes a second mounting base, a driving device, a fixed inclined plate, and a swinging inclined plate. The fixed inclined plate and the swinging inclined plate are respectively located above the conveying device. The fixed inclined plate is fixedly connected to the second mounting base, and the swinging inclined plate is rotatably connected to the second mounting base and can be driven to rotate by the driving device. When the swinging inclined plate is not driven, the swinging inclined plate and the fixed inclined plate cooperate to form a V-shaped buffer groove. The feeding grippers are used to place the droppers into the V-shaped buffer groove. When the swinging inclined plate is driven, the bottom of the V-shaped buffer groove opens and the droppers fall onto the conveying device.

[0009] Beneficial effects: When dropper inspection is required, the dropper lifting mechanism lifts the dropper to the dropper rotating mechanism and brings the dropper into contact with the drive wheel. The drive wheel can drive the dropper to rotate, so that the dropper end can be visually inspected by the appearance inspection equipment. It is also easy to use. Attached Figure Description

[0016] like Figure 2The illustrated drip tube testing line includes a conveying device 1, a feeding device 2, a testing device 3, and a tunnel furnace 4. The feeding device 2 is used to place the processed drip tubes onto the conveying device 1, and the conveying device 1 is used to transport the drip tubes to the testing device 3. Figure 3 , Figure 4 The inspection device 3 includes a mounting frame 31, a light source 32, an appearance inspection device 33 (such as a camera, webcam, or other visual inspection device), a dropper lifting mechanism 34, and a dropper rotating mechanism 35. The light source 32, the appearance inspection device 33, and the dropper rotating mechanism 35 are mounted above the conveying device 1 via the mounting frame 31. The dropper rotating mechanism 35 is located between the light source 32 and the appearance inspection device 33. The dropper lifting mechanism 34 is located below the dropper rotating mechanism 35. The dropper lifting mechanism 34 is used to lift the dropper on the conveying device 1 to the dropper rotating mechanism 35 and suspend both ends of the dropper in the air. The dropper rotating mechanism 35 includes a drive wheel 351, which can contact the lifted dropper and drive it to rotate.

[0017] By adopting the above structure, the feeding device 2 transfers the finished droppers to the conveying device 1. The conveying device 1 can move in a stepping manner, and the conveying device 1 conveys the droppers one by one to the inspection device 3. The dropper lifting mechanism 34 can lift the droppers above it to between the light source 32 and the appearance inspection device 33. The appearance inspection device 33 can perform visual inspection on the suspended dropper end. At the same time, the drive wheel 351 can drive the dropper to rotate, so that the dropper end can be inspected around the whole circle. After the inspection is completed, the dropper is put back onto the conveying device 1 by the dropper lifting mechanism 34 and continues to move to the next station with the conveying device 1.

[0018] The above-described structure is particularly suitable for testing lines that use support at both ends of the dropper for delivery, that is, combining... Figure 5 As shown, the conveying device 1 includes at least two sets of conveying chains 11, with conveying blocks 12 evenly installed on each set of conveying chains 11. The two ends of the dropper are respectively placed in the V-shaped groove in the middle of the conveying block 12. This facilitates the conveying of the cylindrical dropper and ensures that the axis of the dropper is perpendicular to the direction of travel of the conveying chain 11. The dropper lifting mechanism 34 is located in the middle of the two sets of conveying chains 11. It contacts the middle of the dropper from the gap in the middle of the conveying chain 11 and lifts the dropper, so that the two ends of the dropper are suspended in the air so that the two ends of the dropper can be detected.

[0019] Specifically, in combination Figure 4The dropper lifting mechanism 34 includes a vertical sliding mechanism 341 and a lifting slider 342. The vertical sliding mechanism 341 can be an electric slide rail. The lifting slider 342 is mounted on the vertical sliding mechanism 341 and can be driven by the vertical sliding mechanism 341 to move up and down. The top of the lifting slider 342 is set corresponding to the middle of the dropper and can pass between two sets of conveyor chains to be lifted to the drive wheel 351.

[0020] The dropper rotation mechanism 35 includes a first mounting base 352, an adjusting slider 353, and a drive motor 354. The first mounting base 352 is fixedly connected to the mounting bracket 31. The adjusting slider 353 is slidably connected to the first mounting base 352 through an adjusting screw 355. The drive motor 354 is mounted on the bottom of the adjusting slider 353. The output end of the drive motor 354 is connected to the drive wheel 351. In this way, the adjusting slider 353 can be moved up and down by turning the adjusting screw 355, thereby adjusting the position of the drive wheel 351.

[0021] In addition, combined Figure 5 , Figure 6 The feeding device 2 includes a gantry frame 21, feeding grippers 22, and a feeding buffer mechanism 23. The feeding grippers 22 are mounted on the gantry frame 21 and are used to transfer the processed droppers to the feeding buffer mechanism 23. The feeding buffer mechanism 23 is located above the conveying device 1. The feeding buffer mechanism 23 includes a second mounting base 231, a drive device 232, a fixed inclined plate 233, and a swing inclined plate 234. The fixed inclined plate 233 and the swing inclined plate 234 are respectively located above the conveying device 1. The fixed inclined plate 233 is fixedly connected to the second mounting base 231, and the swing inclined plate 234 is fixedly connected to the second mounting base 231. 4 is rotatably connected to the second mounting base 231 and can be driven to rotate by the driving device 232. When the swinging inclined plate 234 is not driven, the swinging inclined plate 234 and the fixed inclined plate 233 cooperate to form a V-shaped buffer groove. The feeding claw 22 is used to place the dropper into the V-shaped buffer groove. When the swinging inclined plate 234 is driven, the bottom of the V-shaped buffer groove opens and the dropper falls onto the conveying device 1. In this way, the feeding buffer mechanism 23 can make it easy for the dropper to be aligned with the concave V-shaped groove in the middle of the conveying block 12 on the conveying device 1, which plays a role in collecting and guiding the feeding dropper.
