Description

Technical Field

[0001] The utility model relates to the technical field of rubber suction cup detection, in particular to a rubber suction cup detection device. Background Art

[0002] With the rapid development of automobiles, the demand for automotive air-conditioning compressor clutches increases year by year. As a core component of the clutch, the quality of the suction cup determines the product performance of the entire clutch. The flatness parameter of the suction cup is one of the most critical indicators of the suction cup. Therefore, the quality control of the suction cup finished product is very important. At present, there is a lack of means for detecting and controlling the flatness of the suction cup product, and only a standard three-dimensional coordinate measuring instrument can be used for detection.

[0003] For example, a suction cup flatness detection device disclosed in a Chinese patent with the publication number CN216523839U places the suction cup to be detected on a product placement rack. By pressing down the pressing head device, the suction cup is brought into contact with the displacement sensor. Whether the flatness of the suction cup is qualified is judged by the data detected by all displacement sensors. The device has a simple structure, realizes automatic detection and judgment in the detection process, and has a high degree of automation.

[0004] However, in the suction cup flatness detection device in the above application, when placing the suction cup, the suction cup may be placed obliquely, resulting in the suction cup being wrinkled and distorted when pressed down, thus affecting the accuracy of the detection. Moreover, the arc surface of the outer arc of the suction cup is not detected and the airtightness of the suction cup is not detected, and the detection range is relatively single. Therefore, there are certain limitations. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a rubber suction cup detection device, which solves the technical problems that in the prior art, when placing the suction cup, the suction cup may be placed obliquely, resulting in the suction cup being wrinkled and distorted when pressed down, thus affecting the accuracy of the detection, and the arc surface of the outer arc of the suction cup is not detected and the airtightness of the suction cup is not detected, and the detection range is relatively single, and achieves the purpose of improving the accuracy of the detection of the rubber suction cup and increasing the detection range.

[0006] To solve the above technical problems, the utility model provides the following technical solution: A rubber suction cup detection device includes a bracket installed on a detection table, and a detection mechanism for detecting the flatness and arc surface of the rubber suction cup is installed on the bracket, and an airtightness detection mechanism for detecting the airtightness of the rubber suction cup is arranged on the flatness detection mechanism.

[0007] The detection mechanism includes a placement disk installed on the detection table, and a placement groove is provided on its upper surface. Pressure sensors are installed at equal intervals in a circular pattern at the center and outside of the interior of the placement groove. The front end of the top of the bracket is installed with an electric lifting rod. The free end of the electric lifting rod penetrates the bracket, and a pressure disk is installed at its bottom. Pressure sensors are also installed at equal intervals in a circular pattern on the outer side of the lower surface of the pressure disk.

[0008] Preferably, a rotation groove is provided on the upper surface of the detection table, the placement disk is installed inside the rotation groove, and the placement groove provided on the placement disk is an arc-shaped groove.

[0009] Preferably, an electric push rod is installed on the right side of the pressure disk. The free end of the electric push rod is installed with a detection pen, and a pressure sensor is also installed inside its outer end. The electric push rod and the pressure disk are connected by a connecting arm.

[0010] Preferably, a rotation motor is installed on the lower surface of the detection table. The output end of the rotation motor is connected to a rotation shaft, which penetrates the detection table and extends into the interior of the rotation groove, and its top is connected to the placement disk.

[0011] Preferably, the airtight detection mechanism includes an air pump installed on the front of the bracket. The air outlet of the air pump is installed with a telescopic hose, and the other end of which penetrates the pressure disk. A barometric monitor is installed at the center of the lower surface of the pressure disk.

[0012] Preferably, a controller is installed at the front end of the right side of the upper surface of the detection table. The detection mechanism and the airtight detection mechanism are respectively electrically connected to the controller.

[0013] By means of the above technical solution, the present utility model provides a rubber suction cup detection device, which has at least the following beneficial effects:

[0014] 1. Through the pressure sensors installed on the placement disk and the pressure disk, by whether all the pressure sensors are triggered, it can be determined whether the flatness of both ends of the rubber suction cup is consistent, thus avoiding the problem that the suction cup is placed obliquely and affects the accuracy of detection.

[0015] 2. After the suction cup is pressed, the air pump is started to inject air into the rubber suction cup. The airtightness of the rubber suction cup can be detected by the change of the air pressure value of the barometric monitor, which improves the detection range of the device.

[0016] 3. In the present utility model, the pressure sensor at the left end of the detection pen is attached to the outer arc surface of the rubber suction cup, and at the same time, the rubber suction cup is rotated by a rotating motor. During this process, the pressure sensor on the detection pen always adheres to the outer arc surface of the rubber suction cup. If the signal of this pressure sensor is interrupted, it indicates that there are uneven situations such as pits on the outer arc surface of the rubber suction cup, and thus it can be determined that the rubber suction cup is a defective product, thereby realizing the detection of the radian of the outer arc surface of the rubber suction cup.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1

[0026] Based on the problem that when placing the suction cup in the existing technology, the suction cup may be placed obliquely, resulting in the suction cup being wrinkled and distorted when pressing down the suction cup, thus affecting the accuracy of detection. This embodiment provides a rubber suction cup detection device. Please refer to Figures 1-4 , this embodiment provides a rubber suction cup detection device, which can make the rubber suction cup lie flat completely and avoid the problem that its obliquity affects the detection accuracy. The rubber suction cup detection device includes a bracket 2 installed on a detection table 1, and a detection mechanism 3 for detecting the flatness and arc surface of the rubber suction cup is installed on the bracket 2. An airtight detection mechanism 4 for detecting the airtightness of the rubber suction cup is arranged on the flatness detection mechanism 3. The rubber suction cup is placed upside down in the groove of the placing plate 301 in the detection mechanism 3, and the pressure sensor 302 arranged inside it is used to ensure the stable placement of the rubber suction cup. Then, by cooperating with the top pressing pressure sensor 302, the flatness of both ends of the rubber suction cup can be detected. Then, the airtightness of the rubber suction cup is detected by the airtight detection mechanism 4 to avoid air leakage and affect the later installation and use.

[0027] Due to the problem that when placing the suction cup in the existing technology, the suction cup may be placed obliquely, resulting in the suction cup being wrinkled and distorted when pressing down the suction cup, thus affecting the accuracy of detection. The device is provided with a detection mechanism 3. The detection mechanism 3 includes a placing plate 301 installed on the detection table 1, and a placing groove is opened on its upper surface. Pressure sensors 302 are installed at equal intervals in a ring shape at the center and outside of the inner part of the placing groove. An electric lifting rod 303 is installed at the front end of the top of the bracket 2. The free end of the electric lifting rod 303 penetrates through the bracket 2, and a pressure plate 304 is installed at its bottom. Pressure sensors 302 are also installed at equal intervals in a ring shape on the outer side of the lower surface of the pressure plate 304. A rotating groove is opened on the upper surface of the detection table 1, and the placing plate 301 is installed inside the rotating groove. The placing groove opened on the placing plate 301 is an arc-shaped groove. When placing the rubber suction cup inside the placing groove on the placing plate 301, one end of the rubber suction cup is completely attached to the bottom wall of the placing groove. At this time, the rubber suction cup contacts the pressure sensor 302 installed inside the placing groove. If a pressure sensor 302 is not triggered, it indicates that this end of the rubber suction cup is uneven, and defective products can be directly measured. If all pressure sensors 302 emit electrical signals, it indicates that the rubber suction cup has been stably placed. At this time, start the electric lifting rod 303 to push the pressure plate 304 downward until the pressure sensor 302 on its lower surface contacts the other end of the rubber suction cup. Referring to the above steps, the flatness of both ends of the rubber suction cup can be measured.

[0028] When detecting the rubber suction cup, the airtightness of the rubber suction cup is also a very important detection item. If its airtightness is insufficient and air leakage occurs, it will directly affect the use of the rubber suction cup. Therefore, the device is also provided with an airtightness detection mechanism 4. The airtightness detection mechanism 4 includes an air pump 401 installed on the front of the bracket 2. The air outlet of the air pump 401 is installed with a telescopic hose 402, and the other end thereof penetrates through the pressure plate 304. A barometric monitor 403 is installed at the center of the lower surface of the pressure plate 304. When the pressure plate 304 fits on the top of the rubber suction cup, a closed space is formed inside the rubber suction cup. At this time, start the air pump 401, and inject air into the rubber suction cup through the telescopic hose 402. Then, the airtightness of the rubber suction cup can be determined by the change in the air pressure value of the barometric monitor 403.

[0029] A controller 5 is installed at the front right end of the upper surface of the test bench 1. The detection mechanism 3 and the airtightness detection mechanism 4 are respectively electrically connected to the controller 5. The specific values obtained in the above detection steps are all transmitted to the display screen on the controller 5, and the normal operation of the device can be directly controlled through the controller 5.

[0030] Embodiment 2

[0031] On the basis of Embodiment 1, as Figures 1-4 shown, when detecting the rubber suction cup, not only its flatness needs to be detected, but the detection of the curvature of its outer arc surface is also equally important. If the outer arc surfaces of the rubber suction cups are different, it will also affect the service life of the rubber suction cup. Therefore, an electric push rod 305 is installed on the right side of the rubber suction cup pressure plate 304 of the device. A detection pen 306 is installed at the free end of the electric push rod 305, and a pressure sensor 302 is also installed inside its outer end. The electric push rod 305 and the pressure plate 304 are connected by a connecting arm 307. A rotary motor 308 is installed on the lower surface of the test bench 1. The output end of the rotary motor 308 is connected to a rotary shaft 309, and it penetrates through the test bench 1 and extends into the inside of the rotating groove. Its top is connected to the placement plate 301. Start the electric push rod 305 to push the pressure sensor 302 at the left end of the detection pen 306 to fit on the outer arc surface of the rubber suction cup. At this time, start the rotary motor 308 to drive the rotary shaft 309 to rotate, and then drive the placement plate 301 at its top to rotate, so as to drive the rubber suction cup inside the placement plate 301 to rotate. During this process, the pressure sensor 302 at the left end of the detection pen 306 always fits on the outer arc surface of the rubber suction cup. If the signal of this pressure sensor 302 is interrupted, it indicates that there are potholes and other uneven conditions on the outer arc surface of the rubber suction cup, and it can be determined that the rubber suction cup is a defective product, thus realizing the detection of the curvature of the outer arc surface of the rubber suction cup.
