Description

Technical Field

[0001] This application relates to the field of sealing ring installation and assembly, and in particular to a sealing ring installation testing device. Background Technology

[0002] Reference Figure 1 Currently, there is a sealing cap comprising a cap body 1 and a sealing ring 2. An insert post 3 is integrally injection-molded into the center of the cap body 1. The insert post 3 is hollow, and a sealing groove 4 for accommodating the sealing ring 2 is formed on the periphery of the cap body 1 around the insert post 3. This sealing cap is mainly used for sealing bottles on dispensing equipment.

[0003] The sealing cap is formed by one-piece injection molding of the cap body, and then the sealing ring is installed into the sealing groove to complete the sealing cap. There are many ways to install the sealing ring onto the cap body. The most traditional method is to manually hold the cap body and press the sealing ring into the sealing groove. However, this method can result in irregular installation of the sealing ring, where the sealing ring may be lifted up in the sealing groove. Due to long working hours, it is difficult for workers to notice any improper installation of the sealing ring, and such sealing caps will affect the sealing performance of the filling bottles during subsequent use.

[0004] Therefore, post-installation testing is necessary. Consequently, a semi-automated installation and testing device has emerged, comprising a conveyor belt for transporting the cover; a height detection device for detecting whether the sealing ring is installed correctly; a qualified product collection box for storing qualified products; a defective product collection box for storing defective products; and a robotic arm for grasping the sealing cover from the conveyor belt and transferring it to the qualified or defective product collection box. In practice, the conveyor belt uses a step-by-step conveying method. The worker stands beside the conveyor belt, installs the sealing ring on the cover, and then the cover continues to be transported along the conveyor belt. The height detection device includes a lifting cylinder and a displacement sensor fixedly connected to the piston rod end of the lifting cylinder. The displacement sensor is pre-set with data. When the lifting cylinder drives the displacement sensor to descend and contact the sealing ring, if the descent distance of the displacement sensor is within the set data range, the sealing ring is installed correctly; otherwise, it is not.

[0005] Regarding the aforementioned technologies, the installation of the sealing ring is still done manually, and the degree of automation needs to be improved. Furthermore, since the sealing ring is circumferential, the displacement sensor of the installation equipment is only set up once, which can only detect one position of the sealing ring. If one end of the sealing ring is tilted up, it cannot be detected, meaning that there are cases where defective products cannot be detected, resulting in low detection accuracy. Summary of the Invention

[0006] To improve the automation level of sealing ring installation and the accuracy of sealing cover inspection, this application provides a sealing ring installation inspection device.

[0007] The sealing ring installation testing device provided in this application adopts the following technical solution: A sealing ring installation and testing device includes a machine body with a rotating disk rotatably mounted on the machine body. Multiple tooling positions are spaced apart along the circumference of the rotating disk. It also includes a cover feeding assembly for conveying covers to the tooling positions; a sealing ring gripping and feeding assembly for placing the sealing rings into the sealing grooves of the covers; a height detection assembly for detecting whether the sealing rings are installed correctly; a qualified product removal assembly for removing qualified sealing covers; and a defective product removal assembly for removing unqualified sealing covers. The cover feeding assembly, sealing ring gripping and feeding assembly, height detection assembly, qualified product removal assembly, and defective product removal assembly are sequentially distributed along the circumference of the rotating disk. The sealing ring gripping and feeding assembly includes a first vibratory plate, a feeding plate connected to the output end of the first vibratory plate, and a clamping component rotatably mounted on the machine body. The clamping component grips the sealing ring on the feeding plate and places it into the sealing groove. The height detection component includes a displacement sensor and a lifting component that drives the displacement sensor to move up and down. The height detection component has at least two parts, and the at least two displacement sensors correspond to two opposite positions on the circumference of the sealing ring.

[0008] By adopting the above technical solution, the cover feeding assembly transports the cover to the tooling position on the rotating disk. The rotating disk then rotates, moving the tooling position to the sealing ring gripping and feeding assembly. A first vibrating plate transports the sealing ring to the feeding plate, and then a clamping component grips the sealing ring and places it into the sealing groove of the cover, which helps improve the automation level of sealing ring installation. Subsequently, the rotating disk continues to move to the height detection assembly to detect the height of the sealing ring and determine if it is qualified. If qualified, the tooling position rotates with the rotating disk to the qualified product unloading assembly for unloading. If unqualified, it moves to the defective product unloading assembly for unloading. The height detection assembly has at least two components, i.e., at least two displacement sensors, with at least two displacement sensors corresponding to the relative positions of the sealing ring. If the height detection at both ends of the sealing ring is qualified, it means that the sealing ring is in the correct position and there will be no other instances of tilting, which helps improve the accuracy of the detection. Furthermore, the rotating disk has multiple tooling positions, allowing for simultaneous cover feeding, sealing ring feeding, height detection, and unloading operations, which helps improve the overall work efficiency.

[0009] Preferably, the rotating disk is provided with a U-shaped groove in the tooling position, the cover feeding assembly is set as a second vibrating disk, the output port of the second vibrating disk is connected to the U-shaped groove, a baffle is provided on the periphery of the rotating disk, and the baffle is provided with an avoidance opening at the output port of the second vibrating disk.

[0010] By adopting the above technical solution, when the cover is output from the output port of the second vibrating plate, it will enter the U-shaped groove through the clearance port. When the rotating plate rotates, the baffle will limit the cover, which helps to prevent the cover from being thrown out of the U-shaped groove during the rotation process.

[0011] Preferably, the output end of the first vibratory feeder is connected to a conveyor belt, the feeding plate is connected to the output end of the conveyor belt, and the machine body is provided above the conveyor belt with a pressure bar to prevent adjacent sealing rings from stacking. The length direction of the pressure bar is parallel to the length direction of the conveyor belt. The end of the pressure bar away from the feeding plate is integrally formed with an inclined upward guide rod, which is inclined upward in the direction away from the feeding plate. The connection between the guide rod and the pressure bar is rounded.

[0012] By adopting the above technical solution, the pressure rod is used to limit the sealing ring, which helps to prevent the sealing ring from stacking during the conveying process. The connection between the guide rod and the pressure rod is set with rounded corners. If the front end of the sealing ring is raised, the rounded corners help the sealing ring to enter under the pressure rod along the shape of the rounded corners, preventing the raised part of the sealing ring from abutting against the pressure rod, making it impossible to convey and causing stacking.

[0013] Preferably, the feeding plate is lifted and lowered on the machine body, and the machine body is provided with a drive component for driving the feeding plate to lift and lower. A waste box is provided on the machine body below the conveyor belt. An air blowing pipe is provided on the side of the feeding plate away from the conveyor belt. When the feeding plate is in the lowered state, the feeding plate is connected to the opening of the waste box, and the air blowing port of the air blowing pipe faces the waste box. A camera is provided on the machine body above the conveyor belt for detecting whether the sealing ring is worn. The camera is signal connected to the drive component.

[0014] By adopting the above technical solution, if the camera detects wear on the sealing ring during the conveying process, i.e., the sealing ring is unqualified, when the sealing ring moves to the feeding plate, the camera transmits a signal to the driving component. The driving component drives the feeding plate to descend and connect with the opening of the waste box. Then, the air blower blows air to blow the sealing ring on the feeding plate into the waste box, thereby realizing the removal of waste.

[0015] Preferably, the machine body is rotatably connected above the conveyor belt to a limiting block for restricting the movement of the sealing ring. The machine body is provided with a swing cylinder for driving the limiting block to rotate. An infrared sensor is provided on the machine body on the conveyor belt for detecting the passage of the sealing ring. The infrared sensor is signal-connected to the swing cylinder.

[0016] By adopting the above technical solution, when the infrared sensor detects that a sealing ring has passed by, it transmits a signal to the swing cylinder. The swing cylinder operates and drives the limit block to rotate, overlapping on the conveyor belt to restrict the subsequent sealing rings from moving further, thereby ensuring that there is only one sealing ring on the feeding plate and preventing the sealing rings from stacking.

[0017] Preferably, the machine body is provided with a lifting plate and a driving cylinder for driving the lifting plate to move up and down. The lifting plate is provided with a rotary cylinder, the rotation axis of the rotary cylinder is arranged vertically, and the clamping component includes a connecting plate fixed to the end of the piston rod of the rotary cylinder and two inner lining claws respectively fixed to both ends of the connecting plate.

[0018] By adopting the above technical solution, when the sealing ring is fed onto the feeding plate, the drive cylinder drives the lifting plate to descend, and the inner lining gripper grabs the sealing ring. Then the lifting plate rises and falls, and the rotary cylinder drives the connecting plate to rotate, so that the inner lining gripper that grabs the sealing ring rotates to correspond with the tooling position, and then descends again, thereby realizing the installation of the sealing ring. In this process, since there are two inner lining grippers on the connecting plate, the installation and gripping of the sealing ring can be carried out simultaneously, which helps to improve the overall work efficiency.

[0019] Preferably, the inner lining claw is installed below the connecting plate by an elastic mechanism that extends and retracts in the vertical direction. The connecting plate is fixedly connected to a fixing sleeve on the periphery of the inner lining claw to press the sealing ring from the inner lining claw into the sealing groove. A guide post that engages with the insertion post is installed in the middle of the inner lining claw.

[0020] By adopting the above technical solution, the inner liner claw descends, and the guide post and the plug-in post are plugged in to play a guiding role. When the inner liner claw abuts against the bottom wall of the cover, the inner liner claw does not move under the action of the elastic mechanism, and the fixed sleeve continues to move downward, thereby pressing the sealing ring from the inner liner claw into the sealing groove.

[0021] Preferably, the qualified product unloading assembly includes an unloading slide and a push cylinder. The unloading slide is connected to the U-shaped groove of the tooling position. A push plate is fixedly installed at the end of the piston rod of the push cylinder, and the push plate is located on the side of the U-shaped groove away from the unloading slide. The push plate slides along the direction of approaching and moving away from the entrance of the unloading slide.

[0022] By adopting the above technical solution, when the sealing cover is qualified after height inspection, the rotating disk rotates, driving the sealing cover to the qualified product unloading assembly. At this time, the cylinder is driven to move, driving the push plate to move, thereby pushing the sealing cover from the U-shaped groove into the unloading slide, realizing the unloading action of the qualified product.

[0023] Preferably, the machine body is provided with a blower hood, which is located on the periphery of the rotating disk and between the defective product unloading assembly and the cover loading assembly, and the blower nozzle of the blower hood faces the U-shaped groove.

[0024] By adopting the above technical solution, after the sealing cover is off the production line, the tooling position will rotate to the blower hood along with the rotating plate. During the actual installation process, there may be dust or dirt in the U-shaped groove due to wear of the sealing ring, which will affect subsequent use. Using the blower hood to blow air into the U-shaped groove will help to make the tooling position cleaner.

[0025] Preferably, the machine body is provided with an installation plate between the cover feeding assembly and the sealing ring gripping feeding assembly. The machine body is provided with a first lifting cylinder that drives the installation plate to rise and fall. An abutment cylinder is installed below the installation plate. A limiting post is provided inside the abutment cylinder to cooperate with the insertion post. The edge of the abutment cylinder abuts against the edge of the cover. Multiple air blowing pipes are installed on the abutment cylinder, and the air blowing ports of the air blowing pipes face the sealing groove.

[0026] By adopting the above technical solution, after the cover is loaded, the rotating disk drives the cover to rotate to the bottom of the mounting plate. The first lifting cylinder drives the mounting plate to descend. At this time, the limiting post and the insertion post are inserted and engaged, and the outer edge of the abutting cylinder abuts against the outer edge of the cover. Then, the air blowing pipe blows air into the sealing groove, which helps to make the sealing groove cleaner and thus helps to prevent the subsequent installation of the sealing ring from being affected.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. The first vibratory feeder neatly conveys the sealing rings, and then the clamping component grabs the sealing rings. Under the action of the rotary cylinder, the clamping component rotates and then places the sealing rings into the sealing groove. This eliminates the need for manual feeding, which helps reduce labor intensity and improve installation efficiency. In addition, at least two height detection components are provided, corresponding to at least two positions opposite the sealing rings, which helps improve the accuracy of detection and thus reduce the defect rate. 2. The pressure bar helps prevent the sealing rings from stacking, and the rounded corners at the connection between the pressure bar and the guide bar help prevent the end of the pressure bar from blocking the sealing ring and affecting its delivery.

Detailed Implementation

[0030] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0031] This application discloses a sealing ring installation testing device.

[0032] Reference Figure 2 and Figure 3The sealing ring installation and testing equipment includes a body 1, on which a rotating disk 2 is rotatably connected. The rotation of the rotating disk 2 is driven by conventional means such as a servo motor. The rotating disk 2 is provided with multiple tooling positions 21. In this application, there are twelve tooling positions 21. The rotating disk 2 is provided with a U-shaped groove 22 for accommodating the sealing cover within the tooling position 21. Along the rotation direction of the rotating disk 2, the body 1 is provided with a cover feeding assembly 3, a blowing assembly 4, a sealing ring gripping and feeding assembly 5, a height detection assembly 6, a qualified product unloading assembly 7, a defective product unloading assembly 8, and a cleaning assembly 9.

[0033] The cover feeding assembly 3 is set as a second vibrating plate 31. The output port of the second vibrating plate 31 is connected to the U-shaped groove 22. A baffle 23 is fixedly installed on the circumferential side of the rotating plate 2. The baffle 23 forms a clearance opening 231 at the output port of the second vibrating plate 31. A distributing cylinder 11 is installed on one side of the rotating plate 2 on the machine body 1. A distributing rod 12 is fixedly installed at the piston rod end of the distributing cylinder 11. The sliding direction of the distributing rod 12 is tangent to the edge of the rotating plate 2. When the first cover enters the U-shaped groove 22, the distributing cylinder 11 operates, causing the distributing rod 12 to slide and block at the clearance opening 231 to prevent the subsequent covers from continuing to move.

[0034] Reference Figure 2 and Figure 4 The blower assembly 4 includes a mounting plate 41 and a first lifting cylinder 42 that drives the mounting plate 41 to rise and fall. A contact cylinder 411 is fixedly connected to the bottom of the mounting plate 41 by bolts. A limiting post 412 is integrally formed in the middle of the contact cylinder 411 to engage with the plug post of the sealing cover. The edge of the contact cylinder 411 abuts against the edge of the cover. Multiple blower pipes 413 are installed on the contact cylinder 411. A dust suction port 414 is also opened on the contact cylinder 411 corresponding to the blower pipes 413. The air outlets of the blower pipes 413 face the sealing groove. The other end of each blower pipe 413 is connected to an air pump.

[0035] When the cover rotates to the blowing assembly 4, the first lifting cylinder 42 drives the mounting plate 41 to descend, so that the limiting post 412 and the insertion post are engaged, and the edge of the abutting cylinder 411 abuts against the edge of the cover. Then, the air pump is used to blow air into the blowing pipe 413, thereby blowing away the debris and dust in the sealing groove and discharging it from the dust suction port 414, which helps to reduce the impact on the subsequent installation of the sealing ring.

[0036] Reference Figure 2 , Figure 5 and Figure 6The sealing ring gripping and feeding assembly 5 includes a first vibratory plate 51, a feeding plate 52 connected to the output end of the first vibratory plate 51, and a clamping component 53 rotatably mounted on the machine body 1. A lifting plate 13 is provided on one side of the rotating plate 2 on the machine body 1. A drive cylinder 14 for driving the lifting plate 13 to rise and fall is also installed on the machine body 1. A rotary cylinder 131 is fixedly mounted on the lifting plate 13. The rotation axis of the rotary cylinder 131 is vertically arranged. The clamping component 53 includes a connecting plate 531 fixed to the upper end of the piston rod of the rotary cylinder 131, and two inner liners. The clamping claws 532 are fixedly installed at both ends of the connecting plate 531 along its length. The clamping claws 532 are installed below the connecting plate 531 through the elastic mechanism 10. The elastic mechanism 10 consists of a compression spring fixed on the connecting plate 531 and a guide cylinder fixedly installed around the compression spring. A fixing sleeve 20 is fixedly installed on the connecting plate 531 around the clamping claws 532 to press the sealing ring into the sealing groove. A guide post is installed in the middle of the clamping claws of the clamping claws 532. The guide post is inserted into the insertion post to play a guiding role.

[0037] When the rotating disk 2 moves the cover to the sealing ring gripping and feeding assembly 5, the drive cylinder 14 drives the lifting plate 13 to descend. At this time, the inner lining gripper 532 grips the sealing ring. Then, the rotating cylinder 131 drives the connecting plate 531 to rotate, so that the inner lining gripper 532 gripping the sealing ring moves to the top of the cover. The drive cylinder 14 then drives the lifting plate 13 to descend, and the inner lining gripper 532 abuts against the bottom wall of the cover. At this time, under the action of the elastic mechanism 10, the inner lining gripper 532 does not move, and the fixed sleeve 20 continues to move, thereby pressing the sealing ring from the inner lining gripper 532 into the sealing groove. There are two inner lining grippers 532. While one inner lining gripper 532 is lifting and gripping the sealing ring, the other inner lining gripper 532 can place the sealing ring at the same time. The two actions are performed simultaneously, which helps to improve the overall work efficiency.

[0038] The machine body 1 is equipped with a pressure plate 15 above the rotating disk 2. When the tooling position 21 moves to the sealing ring gripping and feeding assembly 5, the pressure plate 15 is located above the cover when feeding the sealing ring, in order to prevent the cover from being lifted by the inner liner gripper 532.

[0039] The machine body 1 is equipped with a conveyor belt 16 at the output end of the first vibrating plate 51. The conveyor belt 16 is moved by a motor. The feeding plate 52 is connected to the output end of the conveyor belt 16. The machine body 1 is fixedly installed above the conveyor belt 16 to prevent the sealing rings from stacking during the conveying process. The length direction of the pressure rod 30 is parallel to the length direction of the conveyor belt 16.

[0040] The end of the pressure rod 30 away from the feeding plate 52 is integrally formed with a guide rod 301. The guide rod 301 is inclined upward along the side away from the feeding plate 52. The connection between the pressure rod 30 and the guide rod 301 is rounded. If the front end of the sealing ring is raised, the rounded corner helps to make the sealing ring move along the bottom of the pressure rod 30, preventing the raised part of the sealing ring from abutting against the pressure rod 30 and becoming unable to move, thus preventing stacking.

[0041] The machine body 1 is rotatably connected above the conveyor belt 16 to a limiting block 40 for restricting the movement of the sealing ring. A swing cylinder 401 for driving the limiting block 40 to rotate is fixedly installed on the machine body 1. The limiting block 40 has a clearance groove for avoiding the pressure rod 30. An infrared sensor is also installed on the machine body 1 on the conveyor belt 16. The infrared sensor is connected to the swing cylinder 401. When the infrared sensor detects that a sealing ring has been conveyed, it means that a sealing ring on the conveyor belt 16 has entered the loading plate 52. At this time, the infrared sensor transmits a signal to the swing cylinder 401, which drives the limiting block 40 to rotate and mount it on the pressure rod 30. At the same time, the limiting block 40 abuts against the conveyor belt 16, thereby preventing the sealing ring from continuing to move forward and helping to prevent the phenomenon of sealing ring stacking on the loading plate 52.

[0042] The machine body 1 is also equipped with a drive component for driving the lifting of the feeding plate 52. The drive component is a second lifting cylinder 521. The feeding plate 52 is fixedly installed at the end of the piston rod of the second lifting cylinder 521. A waste box 50 is installed on the machine body 1 below the conveyor belt 16. An air blowing pipe 522 is installed on the side of the feeding plate 52 away from the conveyor belt 16. The air blowing pipe 522 is connected to an air pump. When the feeding plate 52 is in the descending state, the feeding plate 52 is connected to the opening of the waste box 50. The air blowing port of the air blowing pipe 522 faces the waste box 50. A camera 60 is installed on the machine body 1 above the conveyor belt 16 to detect whether there is wear on the surface of the sealing ring. The camera 60 is connected to the second lifting cylinder 521.

[0043] When the camera 60 detects that the surface of the sealing ring is worn significantly, it transmits a signal to the second lifting cylinder 521, causing the feeding plate 52 to descend. When the feeding plate 52 descends to connect with the opening of the waste box 50, the air blowing pipe 522 blows the sealing ring into the waste box 50 to remove the waste.

[0044] Reference Figure 2 and Figure 7, the height detection component 6 includes a displacement sensor 61 and a lifting member for driving the displacement sensor 61 to lift and lower. The lifting member is set as the third lifting cylinder 62. A receiving plate 621 is fixedly installed at the end of the piston rod of the third lifting cylinder 62, and the displacement sensor 61 is installed on the receiving plate 621. In this application, two height detection components 6 are provided and arranged in sequence along the rotating disk 2. The two displacement sensors 61 respectively detect the circumferentially opposite positions of the sealing ring. By using the two displacement sensors 61 to respectively detect two opposite positions of the sealing ring, it helps to improve the accuracy of height detection.

[0045] The structures and principles of the qualified product offline component 7 and the defective product offline component 8 are the same. Now, taking the qualified product offline component 7 as an example for illustration, the qualified product offline component 7 includes an offline slideway 71 and a pushing cylinder 72. A pushing plate 721 is fixedly connected to the end of the piston rod of the pushing cylinder 72. The offline slideway 71 is connected to the U-shaped groove 22. The pushing plate 721 is located on the side of the U-shaped groove 22 away from the offline slideway 71. The sliding direction of the pushing plate 721 is parallel to the radial direction of the rotating disk 2, that is, the pushing plate 721 slides along the direction of approaching and departing from the entrance of the offline slideway 71.

[0046] When it is detected as a qualified product after height detection, the rotating disk 2 drives the sealing cover to move to the qualified product offline component 7. At this time, the pushing cylinder 72 operates, causing the pushing plate 721 to push the sealing cover, so that the sealing cover enters the offline slideway 71, realizing the offline of the qualified product. The same applies to unqualified products and will not be elaborated here.

[0047] The cleaning component 9 is set as a blowing hood 91. The air inlet of the blowing hood 91 is connected to a small fan. The blowing outlet of the blowing hood 91 faces the U-shaped groove 22. When the rotating disk 2 drives the empty tooling position 21 to come under the blowing hood 91, the blowing hood 91 blows air into the U-shaped groove 22, which helps to prevent dirt from being present in the U-shaped groove 22 due to dust or wear of the sealing ring, affecting subsequent assembly operations.

[0048] The implementation principle of a sealing ring installation detection device in an embodiment of this application is as follows: The cover body is conveyed into the tooling position 21 by using the second vibrating disk 31, and then the air blowing pipe 413 blows air into the sealing groove to blow away dust and other sundries. Then the tooling position 21 continues to move. The first vibrating disk 51 conveys the sealing ring, and the inner lining gripper 532 performs the feeding operation on the sealing ring, realizing the automatic feeding operation of the sealing ring, improving the automation degree of the sealing ring installation. Using the two displacement sensors 61 to detect two circumferentially opposite positions of the sealing ring helps to improve the detection accuracy of the installation position of the sealing ring.

[0049] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
