Description

Technical Field

[0001] The invention relates to the technical field of rubber ring production and detection, and in particular to a device capable of batch detecting defective rubber rings. Background Art

[0002] At present, in the production process of rubber rings, there will be situations where the burrs are too large or the weld marks of the rubber rings are too large. When the burrs of the rubber rings are too large, the seal will leak. When the fusion of the sol position of the rubber ring is poor, long-term use will cause the sealing medium to seep from the sol marks or even cause the rubber ring to break. At present, for the above two important indicators that affect the sealing of rubber rings, both manufacturers and users mainly use the size of the burrs visually and the amount of stretching of the rubber rings to visually check whether there are melt marks. This type of detection has the following defects: 1. Visual inspection is used, and the standards are not unified. There is an inaccurate judgment of the size of the burrs and melt marks of the rubber rings, which causes defective products to flow into qualified products, posing quality risks.

[0003] 2. Visual inspection can only achieve the effect of random inspection, and it is difficult to conduct large-scale inspection. There is a possibility of batch waste, resulting in large-scale product sealing failure or even recall. Summary of the invention

[0004] According to the above technical problems, the present invention provides a device that can batch detect defective rubber rings, including a feeding vibration plate, a conveyor belt to be inspected, a loading manipulator, a stretching instrument, a two-dimensional detector, a defective product circulation box, a discharge manipulator, a discharge conveyor belt, a qualified product circulation box, an electrical control box, and a program control console. The feeding vibration plate is provided with a feeding port, and a conveyor belt to be inspected and a discharge conveyor belt are provided on the left side of the feeding vibration plate. The right end of the conveyor belt to be inspected is in contact with the feeding port of the feeding vibration plate, the conveyor belt to be inspected is provided with a loading manipulator, and the right end of the discharge conveyor belt is provided with a discharge manipulator. A stretching instrument is provided between the conveyor belt to be inspected and the discharge conveyor belt, a two-dimensional detector is provided on the upper side of the stretching instrument, and a qualified product circulation box is provided on the left end of the discharge conveyor belt. The feeding vibration plate, the conveyor belt to be inspected, the loading manipulator, the stretching instrument, the two-dimensional detector, the discharge manipulator, and the discharge conveyor belt are electrically connected to each other, and their actions are controlled by the electrical control box and the program control console arranged on the ground;

[0005] The stretching instrument includes a driving cylinder, a mounting platform, a defective product delivery port, a stretching disk, a boss, a slot, a vertical plate, a sliding rod, a guide rod, a reset spring, a support block, a guide hole, and a sliding hole. A stretching disk is provided on the upper side of the mounting platform, and the stretching disk is composed of three equally divided fan-shaped disk-shaped structures with central conical holes. A support block is provided at the bottom of the stretching disk. A vertical plate is provided on the outer side of the stretching disk. There are three vertical plates, and the three vertical plates are evenly spaced and arranged on the mounting platform. A guide hole and a sliding hole are opened on the vertical plate. A guide rod and a sliding rod are slidably installed in the guide hole and the sliding hole. One end of the guide rod and the sliding rod are fixedly connected to the outer wall of the stretching disk and the support block respectively. A reset spring is sleeved on the guide rod. A driving cylinder is provided at the bottom of the mounting platform. The driving shaft of the driving cylinder passes through the hole pre-opened in the center of the mounting platform upward and extends into the conical hole in the center of the stretching disk.

It can perform a two-dimensional full inspection test on the burrs and melt marks of rubber rings produced or entering the factory. It has a unified standard for judging the size of the burrs and melt marks of rubber rings, thereby avoiding the situation where defective products flow into qualified products, thereby avoiding the situation where large-area sealing failures of the same type of sealing mechanisms are avoided, and greatly reducing quality risks;

[0010] 2. By setting bosses and slots of different diameters on the stretching disk, rubber rings of different specifications can be tested, which increases the applicable scope of the equipment. Unqualified rubber rings are directly put into the defective product flow box by the unloading robot, eliminating the possibility of them being mixed into qualified products.

[0023] Furthermore, the diameter of the boss 406 increases downward.

[0024] Embodiment 2:

[0025] Working principle: The rubber ring is transported to the inspection conveyor belt 2 through the feeding vibration plate 1. After being transported to the loading position by the inspection conveyor belt 2, the rubber ring is installed on the stretching instrument 4 through the grabbing on the loading robot 3. Then the stretching instrument 4 stretches the rubber ring according to the specifications of different rubber rings. The rubber ring is stretched to the set value. The secondary detector collects the contour data of the tested rubber ring. If the burrs and dissolution marks do not meet the standards, the unloading robot 7 grabs the rubber ring and puts it into the defective product flow box 6; if the tested rubber ring meets the standards, the unloading robot 7 puts the rubber ring on the unloading conveyor belt 8, and the rubber ring is transported to the qualified product flow box 9 through the unloading conveyor belt 8. Specifically:

[0026] The feeding vibration plate 1 is the feeding port of the whole detection equipment. When the production line is started, a large number of rubber rings can be poured into the feeding vibration plate 1. The feeding vibration plate 1 automatically sorts the rubber rings by vibration and transports them to the conveyor belt 2 to be inspected. The conveyor belt 2 to be inspected is located between the feeding vibration plate 1 and the feeding manipulator 3, and is used to transport the rubber rings sorted by the vibration plate. The speed of the inspection conveyor belt is adjustable, and its speed is adjusted by the electrical control box. The conveying speed of the rubber ring is transmitted to the program console 11 through the electrical control box. The program console 11 can adjust the initial and grasping positions of the feeding manipulator 3 according to the data of the conveyor belt 2 to be inspected by the electrical control box;

[0027] The stretching instrument 4 is between the loading manipulator 3 and the unloading manipulator 7. The program console 11 controls the opening and closing speed and opening and closing size of the stretching instrument 4 according to the matching signals of each mechanism and the stretching amount of the rubber ring being tested;

[0028] The stretching disk 405 is a disk-shaped structure with a vertebral hole in the center. The disk-shaped structure is a fan-shaped disk-shaped structure with three equally divided central conical holes. The central conical hole cooperates with the driving shaft 402 of the driving cylinder 401. The driving cylinder 401 is used to drive the axial displacement of the driving shaft 402. The driving cylinder 401 is provided with a position sensor for controlling the displacement of the cylinder, and the displacement data is transmitted to the program console 11 for matching the running speed of the entire device. When the driving shaft 402 is stretched upward, the disk-shaped structure with the vertebral hole opens, the reset spring 411 is compressed, the driving shaft 402 moves downward, and the stretching disk 405 is reset to a closed state under the action of the reset spring 411;

[0029] When the stretching instrument 4 stretches the rubber ring to the set position, the two-dimensional detector 5 starts to scan the outer contour of the rubber ring and judge whether the burrs and sol marks on the rubber ring meet the requirements. If the rubber ring is qualified, the two-dimensional detector 5 outputs a signal to the unloading robot 7, so that the unloading robot 7 places the rubber ring on the unloading conveyor belt 8, and transmits it to the qualified product flow box 9 through the unloading conveyor belt 8; if the rubber ring is unqualified, the two-dimensional detector 5 outputs a signal to the unloading robot 7, so that the unloading robot 7 puts the rubber ring into the defective product flow box 6 through the defective product delivery port 404.
