Description

Technical Field

[0001] This utility model relates to the field of elasticity detection and sieving, and in particular to an automatic elasticity detection and sieving device. Background Technology

[0002] For some containers used to hold liquids, elastic seals are used for sealing. The elasticity of the seals must meet the required standards; if the elasticity does not meet the product's requirements, an effective seal cannot be achieved. Therefore, it is necessary to test and sort the seals based on their elasticity, but manual testing and sorting are obviously inefficient. Utility Model Content

[0003] The purpose of this invention is to address the problems existing in the background technology by proposing an automatic elasticity detection and sorting device that can automatically detect and sort the elasticity of sealing components, with high detection efficiency and a high degree of automation.

[0004] The technical solution of this utility model is an automatic elasticity detection and screening device, including an elasticity detection device and a sorting mechanism. The elasticity detection device includes an elasticity detection mechanism, a cabinet, and a mounting shell, a mounting base, and a central control console mounted on the cabinet. The elasticity detection mechanism includes a turntable rotatably mounted on the mounting shell, a motor mounted on the mounting shell and driving the turntable to rotate, an electric cylinder vertically mounted on the mounting base, and a pressure sensor mounted at the bottom of the electric cylinder. The pressure sensor is communicatively connected to the central control console, and the central control console is controlled by the motor and the electric cylinder. The outer circumference of the upper surface of the turntable has multiple uniformly distributed workstation slots. The sorting mechanism includes a guide component one and a waste box mounted on the cabinet, a guide component two inclinedly connected to the top of the waste box, an air blowing pipe one that blows qualified seals in one workstation slot of the guide component one into the inclined guide component one, an air blowing pipe two that blows unqualified seals in one workstation slot of the guide component two into the guide component two, and two solenoid valves that control the gas flow in the air blowing pipe one and the air blowing pipe two, respectively.

[0005] Preferably, the sorting mechanism further includes fiber optic sensor one and fiber optic sensor two disposed on the mounting housing.

[0006] Preferably, the turntable is open in the middle, and both the first and second air blowing pipes extend upward from the middle of the turntable. The outer end of the work station slot has a slot, and the first and second fiber optic sensors face the slots of the two work station slots respectively when detecting the seal.

[0007] Preferably, the mounting base is provided with a pressure plate, and both sides of the outer end of the pressure plate have upwardly inclined folded plate portions. When the seal initially enters the corresponding work station groove, it is pressed down into the work station groove by the outer end of the pressure plate.

[0008] Preferably, eight workstation slots are evenly distributed.

[0009] Preferably, the end of the workstation slot near the central axis of the turntable is provided with a groove extending toward the central axis of the turntable.

[0010] Preferably, the elasticity testing mechanism and the sorting mechanism are both arranged in two symmetrical sets.

[0011] Compared with existing technologies, this utility model has the following beneficial technical effects: This utility model can automatically perform elasticity detection and sorting of sealing components. During detection, an electric cylinder drives a pressure sensor to move downwards, intermittently detecting the elasticity of the sealing component that has rotated to below the pressure sensor, resulting in high detection efficiency and a high degree of automation. For sealing components that pass the elasticity test, they are blown into the guide component through air pipe one. For sealing components that fail the elasticity test, they are blown into the guide component two through air pipe two, thereby achieving the sorting of qualified and unqualified workpieces.

[0014] like Figures 1-5 As shown in the figure, the elasticity automatic detection and screening equipment proposed in this embodiment includes an elasticity detection device and a sorting mechanism.

[0015] The elasticity testing device includes an elasticity testing mechanism, a cabinet 29, and a mounting shell 13, a mounting base 19, and a central control console 30 mounted on the cabinet 29. Two sets of elasticity testing mechanisms are symmetrically arranged to improve testing efficiency. The elasticity testing mechanism includes a turntable 17 rotatably mounted on the mounting shell 13, a motor mounted on the mounting shell 13 and driving the turntable 17 to rotate, an electric cylinder 20 vertically mounted on the mounting base 19, and a pressure sensor 21 located at the bottom of the electric cylinder 20. The pressure sensor 21 is communicatively connected to the central control console 30, which is controlled by the motor and the electric cylinder 20. The upper surface of the turntable 17 has multiple evenly distributed workstation slots 171 on its outer periphery. These workstation slots 171 sequentially receive the conveyed sealing components during rotation. After the seal is delivered to the initial position in the work station slot 171, the intermittent rotation of the turntable 17 transports the seal to below the pressure sensor 21. Then, the electric cylinder 20 drives the pressure sensor 21 downwards, pressing it against the seal to detect the pressure, i.e., the seal's elasticity. The pressure sensor 21 is communicatively connected to the central control panel 30, transmitting the detection results there. The central control panel 30 is connected to the motor and the electric cylinder 20, controlling the motor to drive the turntable 17 to rotate intermittently, and also controlling the electric cylinder 20 to drive the pressure sensor 21 downwards to detect the seal's elasticity. After detection, the central control panel 30 controls the electric cylinder 20 to drive the pressure sensor 21 upwards.

[0016] like Figure 4 As shown, a pressure plate 18 is provided on the mounting base 19. Both sides of the outer end of the pressure plate 18 have upwardly inclined folded portions in the width direction. When the seal is conveyed to the pressure plate 18, the folded portions act as guides. When the seal initially enters the corresponding work station slot 171, it is pressed down into the work station slot 171 by the outer end of the pressure plate 18, preventing the rear seal from squeezing the foremost seal out of its initial position in the work station slot 171. However, when the motor drives the turntable 17 to rotate, the turntable 17 can still rotate the seal pressed by the pressure plate 18, thus opening the seal.

[0017] like Figure 4 As shown, eight workstation slots 171 are evenly distributed, but other numbers can be designed as needed, but at least four. One end of the workstation slot 171 near the central axis of the turntable 17 is provided with a groove extending towards the central axis of the turntable 17, which facilitates subsequent air blowing through the air blowing pipe to effectively blow off the seal at the workstation slot 171.

[0018] Two sets of sorting mechanisms are symmetrically arranged, each corresponding to one of the elasticity detection mechanisms. The sorting mechanisms include a guide component 22 and a waste bin 28 mounted on the cabinet 29; a guide component 24 inclinedly connected to the top of the waste bin 28; fiber optic sensors 23 and 25 mounted on the mounting housing 13; an air blowing pipe 26 that blows qualified seals from the workstation slot 171 on one side of the guide component 22 into the inclined guide component 22; an air blowing pipe 27 that blows unqualified seals from the workstation slot 171 on one side of the guide component 24 into the guide component 24; and two solenoid valves that control the gas flow in the air blowing pipes 26 and 27 respectively. Both the guide component 22 and the guide component 24 are cylindrical structures with inclined slides. Both the first air blowing pipe 26 and the second air blowing pipe 27 are installed on the mounting shell 13 and are connected to an external high-pressure air source. Two solenoid valves in the middle are used to control the opening and closing of the corresponding passages of the two air blowing pipes. When the passage is open, the corresponding air blowing pipe can spray high-pressure gas. The gas pressure is sufficient to blow the seal off the work station groove 171.

[0019] When the pressure sensor 21 transmits the elasticity detection result to the central control unit 30, the central control unit 30 determines whether the elasticity is qualified according to the preset qualified elasticity range. If the detected elasticity is within the qualified elasticity range, the seal is qualified. When the turntable 17 rotates the seal to the side of the guide component 22, the central control unit 30 controls the solenoid valve to open the air blowing pipe 26. The air blowing pipe 26 blows air into the seal, causing the seal to fall into the inclined guide component 22, where the seal will slide down along the inclined direction. If the elasticity of the seal is unqualified, when the turntable 17 rotates the seal to the side of the guide component 24, another solenoid valve opens the air blowing pipe 27. The air blowing pipe 27 blows air into the seal, causing the seal to fall into the inclined guide component 24, where the seal will slide down into the waste box 28 for collection.

[0020] like Figure 4 As shown, the turntable 17 is open in the middle, and both the first air pipe 26 and the second air pipe 27 extend upward from the middle of the turntable 17. The outer end of the workstation slot 171 has an opening. When the fiber optic sensor 1 23 and the second fiber optic sensor 25 detect the seal, they face the openings of the two workstation slots 171 respectively. If there is a seal at the workstation slot 171, the outer end of the seal can be detected by the fiber optic sensor. The fiber optic sensor detects whether there is a seal at the workstation slot 171 through the corresponding opening.

[0021] In addition, the entire equipment is fed through a feeding mechanism, which sequentially transports the seals to be tested to multiple workstation slots 171. The feeding mechanism includes a housing 1, a vibratory feeder 2 housed within the housing 1, a conveying track 5 with a conveying channel running through the length of the housing and one end connected to the discharge end of the vibratory feeder 2, a support assembly mounted on the housing 1 for installing the conveying track 5, and a cutting-off assembly for controlling the interruption or unobstructed flow of the conveying channel of the conveying track 5. Two sets of vibratory feeders 2, conveying tracks 5, support assemblies, and cutting-off assemblies are symmetrically arranged to improve feeding efficiency. The vibratory feeder 2 has a spiral feeding channel 201, which is inclined at the top and feeds the seals in a spiral pattern during vibration. The top of the housing 1 has a feeding port 101 to facilitate workers adding the seals to be tested into the vibratory feeder 2. When the seal is a bowl-shaped seal, a bracket 3 is installed inside the housing 1. A lever 4, which actuates the seal, is located at the bottom of the bracket 3. The lower part of the lever 4 is bent outwards. The lever 4 is located inside the bottom of the spiral feed channel 201, with a certain gap. One end of the bowl-shaped seal is a small opening, and the other end is a large opening, with the diameter of the large opening being larger than the diameter of the small opening. The vibrating plate 2 needs to convey the seal with the small opening facing upwards. If the seal is intended to enter the bottom of the spiral feed channel 201 with the small opening facing upwards, it will pass smoothly through the gap between the lever 4 and the spiral feed channel 201. If the seal is intended to enter the bottom of the spiral feed channel 201 with the large opening facing upwards, the seal will be blocked by the lever 4 when it moves to the gap area, but the seal will continue to move, thus being flipped to a small opening facing upwards. This achieves the purpose of adjusting the distribution of the seals, ensuring that all seals ultimately conveyed to the conveying track 5 by the vibrating plate 2 are distributed with the small opening facing upwards. If the seal is not a bowl-shaped structure and the position of the seal during feeding can be detected by the elasticity detection device, then bracket 3 and lever 4 are not designed.

[0022] The cutting-off assembly includes a connecting frame 14 mounted on the mounting housing 13, a cylinder 15 tilted on the connecting frame 14, and a baffle 16 located at the telescopic end of the cylinder 15. The upper part of the baffle 16 is a vertical plate. The cylinder 15 is telescopically controlled by the central control panel 30. The end of the conveying track 5 away from the vibratory feeder 2 has a notch 501. When the baffle 16 tilts upward and moves into the notch 501, it blocks the conveying of subsequent seals inside the conveying track 5. When the cylinder 15 retracts, it drives the baffle 16 to tilt upward, the baffle 16 passes through the notch 501, and the top of the baffle 16 enters the inside of the conveying track 5, blocking the seals conveyed by the vibratory feeder 2 from the rear, thus stopping the feeding. When feeding needs to continue, the cylinder 15 is extended, and the cylinder 15 tilts the baffle 16 downward, removing the baffle 16 from the inside of the conveying track 5, releasing the obstruction to the conveying track 5, and the conveying track 5 resumes smooth feeding.

[0023] like Figure 2 and Figure 3As shown, the support assembly includes a transverse frame 6, a lifting frame 7, bolt 1 8, a mounting platform 9, bolt 2 10, a fixing frame 11, and bolt 3 12. The conveyor track 5 is mounted on the transverse frame 6. The lifting frame 7 has horizontally distributed slotted holes. Bolt 1 8 passes through these slotted holes and is threaded onto the transverse frame 6, allowing for fine-tuning of the transverse frame 6's lateral position by adjusting the position of bolt 1 8 through the slotted holes. The mounting platform 9 is located below the lifting frame 7. Bolt 2 10 is vertically mounted at the bottom of the lifting frame 7 and is threaded with two nuts 1, which are respectively fastened to the upper and lower sides of the top of the mounting platform 9. This allows for adjustment of the height of the lifting frame 7 by adjusting the position of the two nuts 1. Bolt 3 12 is vertically mounted at the bottom of the fixing frame 11 and is threaded with two nuts 2, which are respectively fastened to the upper and lower sides of the bottom of the mounting platform 9. The fixing frame 11 is mounted on the housing 1, allowing for adjustment of the height of the mounting platform 9 by adjusting the position of the two nuts 2. By comprehensively adjusting the bolts and nuts, the feed end of the conveying track 5 can be connected and aligned with the discharge end of the spiral feed channel 201 to accurately receive the sealing parts fed by the vibrating plate 2.

[0024] This embodiment can automatically perform elasticity testing and sorting of seals. During testing, one seal is conveyed to the initial position of the workstation slot 171 at a time. As the turntable 17 rotates, the pressure sensor 21 is driven downward by the electric cylinder 20 to intermittently test the elasticity of the seals that have rotated to below the pressure sensor 21, resulting in high testing efficiency and automation. For seals that pass the elasticity test, they are blown down into the guide component 22 through the first air pipe 26. For seals that fail the elasticity test, they are blown down into the guide component 24 through the second air pipe 27 and collected by the waste box 28, thereby achieving the sorting of qualified and unqualified workpieces.

[0025] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
