Description

Technical Field

[0001] This utility model relates to the field of automated detection and sorting technology for thin ceramic materials, specifically a ceramic blade detection device. Background Technology

[0002] Loading, unloading, and transporting thin ceramic products in automated equipment is very troublesome because the material is brittle and thin. The slightest carelessness can easily cause irreparable damage to the material in the equipment. If the most common vibratory feeder feeding method is used, the material may collide with each other or with the vibratory feeder, which can easily cause damage. Therefore, this method is not recommended.

[0003] Robots are used for loading and unloading, but the end effector of robots has various methods. The most common one is mechanical gripping, which can easily damage the materials, so it is not advisable. Furthermore, since the materials are non-metallic, magnetic attraction is also not advisable.

[0004] Therefore, a ceramic blade testing device is proposed to solve the above problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a ceramic blade inspection device, which has the advantages of non-destructive feeding of non-metallic thin sheet materials, compact structure, high space utilization, and good compatibility with high-precision robot positioning and visual inspection. It solves the problems of difficulty in non-destructive feeding of non-metallic thin sheet materials, high cost of tray conveyor belts, excessive space occupation, and low positioning accuracy of robot loading and unloading.

[0007] (II) Technical Solution

[0008] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A ceramic blade testing device, characterized in that it includes:

[0009] The robot loading and photography unit is equipped with a loading robot and a first vacuum sponge suction cup. The end effector of the loading robot adopts the first vacuum sponge suction cup.

[0010] The Tray conveyor belt unit consists of two parallel Tray conveyor belts, each comprising two parallel narrow suspended belt lines. The narrow suspended belt lines are mounted on a platform via linear guide rails and are equipped with a feed cylinder, a material separation cylinder, a material blocking cylinder, and a lifting cylinder.

[0011] A modular moving camera unit includes a module slide driven by a servo motor, a material limiting structure is provided on the module slide, and a camera adapted to the material is provided above the module slide.

[0012] The robot sorting and unloading unit is equipped with an unloading robot and a second vacuum sponge suction cup. The end effector of the unloading robot adopts the second vacuum sponge suction cup.

[0013] The beneficial effects of this utility model are:

[0014] 1) The ceramic blade inspection equipment uses vacuum sponge suction cups as the end effectors of the loading and unloading robots, which reduces the damage caused when the suction cups come into contact with the materials. Compared with traditional gripper gripping, vacuum adsorption gripping requires less operating space and can grip materials in narrower spaces. At the same time, vacuum adsorption does not interfere with the bottom surface of the materials, and this equipment also allows for suspended bottom photography, which has the advantage of non-destructive loading and unloading of non-metallic thin sheet materials.

[0015] 2) In this ceramic blade inspection equipment, the feeding robot completes three actions: material picking, aerial hovering for photography, and material placement. The general use of the robot is only to transport materials. Compared with the traditional use, the robot in this patent adds a hovering for photography process. It relies on the robot's precision to enable the robot's end effector to enter the camera's field of view and hover for photography. It has the advantages of making full use of the robot's performance and saving the cost and space of the sensors and mechanical limiting structures required for the positioning of the tested object in the traditional way.

[0016] 3) The ceramic blade testing equipment, with its narrow suspended belt conveyor, adopts a suspended structure and a split design that saves a lot of space. In general equipment, the entire moving parts are contained inside the frame, while leaving them exposed can reduce the width of the platform and the width of the entire frame. The split design allows the material blocking cylinder and the lifting cylinder to be located directly below the narrow suspended belt conveyor, thus not occupying the space on the left and right sides of the narrow suspended belt conveyor, and has the advantages of compact structure and high space utilization.

[0017] 4) This ceramic blade inspection equipment has a camera above the module slide for taking pictures and inspections. The function of the module slide is to make a single material move in a straight line to complete the picture inspection. After the picture is taken, the unloading robot needs to pick up and unload the material at a fixed point. In order to prevent the material from deviating in position during the movement, a mechanical limiter needs to move with the material. There is a material limiter structure with a slot with a size similar to the material on the module slide as a mechanical limiter. Relying on the accuracy of the servo motor and the repeatability of the module slide, the positioning requirements of the unloading robot can be fully met, which has the advantage of high positioning accuracy of robot unloading and loading.

[0018] Based on the above technical solution, the present invention can be further improved as follows.

[0019] Furthermore, both the first vacuum sponge suction cup and the second vacuum sponge suction cup are used for the non-destructive adsorption and handling of non-metallic sheet materials.

[0020] The advantage of adopting the above-mentioned further solution is that vacuum adsorption gripping requires less operating space compared with traditional gripper gripping, and can grip materials in narrower spaces.

[0021] Furthermore, the feeding and receiving electric cylinder is driven by a stepper motor.

[0022] The beneficial effect of adopting the above-mentioned further solution is that the feeding and unloading electric cylinder lowers a tray into the narrow suspended belt conveyor, and the tray above is blocked by the material separating cylinder. Since the tray is very thin, there are certain precision requirements for driving the feeding and unloading electric cylinder. Therefore, a stepper motor is used to drive the feeding and unloading electric cylinder.

[0023] Furthermore, the material limiting structure has a groove that matches the shape of the material, and the edge of the groove is chamfered.

[0024] The beneficial effect of adopting the above-mentioned further solution is that the groove of the material limiting structure matches the shape of the material and the edge is chamfered. The chamfer is within the allowable deviation range for the material to enter the groove. If there is a slight deviation, the material will still slide into the groove along the chamfered edge.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] In the embodiments, by Figure 1-9 This invention provides a ceramic blade testing device, comprising:

[0037] The robot loading and photography unit 1 is equipped with a loading robot 101 and a first vacuum sponge suction cup 102. The end effector of the loading robot 101 adopts the first vacuum sponge suction cup 102.

[0038] Tray conveyor belt unit 2, the Tray conveyor belt unit 2 is arranged in two parallel lines. The Tray conveyor belt unit 2 includes two parallel narrow suspended belt lines 201. The narrow suspended belt lines 201 are installed on the platform through linear guide rails and are equipped with a feeding and receiving electric cylinder 202, a material separating cylinder 203, a material blocking cylinder 204 and a lifting cylinder 205.

[0039] The module moving photography unit 3 includes a module slide 301 driven by a servo motor, a material limiting structure 302 is provided on the module slide 301, and a camera 303 adapted to the material is provided above the module slide 301.

[0040] The robot sorting and unloading unit 4 is equipped with an unloading robot 401 and a second vacuum sponge suction cup 402. The end effector of the unloading robot 401 adopts the second vacuum sponge suction cup 402.

[0041] Both the first vacuum sponge suction cup 102 and the second vacuum sponge suction cup 402 are used for non-destructive adsorption and handling of non-metallic sheet materials.

[0042] The feeding and receiving electric cylinder 202 is driven by a stepper motor;

[0043] The material limiting structure 302 has a groove that matches the shape of the material, and the edge of the groove is chamfered.

[0044] Working principle:

[0045] Step 1: The material feeding and take-up cylinder 202 lowers a tray into the narrow suspended belt conveyor 201. The tray is blocked by the material separating cylinder 203. Since the tray is very thin, the driving of the material feeding and take-up cylinder 202 has certain precision requirements. Here, a stepper motor is used to drive the cylinder.

[0046] Step 2: After the Tray enters the narrow suspended conveyor belt 201, it moves forward and reaches the pick-up / placement position. It is blocked by the material blocking cylinder 204 and then lifted by the lifting cylinder 205. The loading robot 101 / unloading robot 401 then picks up / places the material. After the loading robot 101 grabs the material, it moves to the position above the camera 303 and stops to take a picture for detection. After the picture detection is completed, it continues to move to the material placement position and puts the material into the material limiting structure 302 on the module slide 301. After this process is completed, the Tray enters the Tray collection area on the other side. It is also lifted by the material receiving and placing electric cylinder 202 and then separated by the material separating cylinder 203 to complete the collection of the empty Tray.

[0047] Step 3: Another narrow suspended belt conveyor 201 operates on the same principle as this belt conveyor, except that the working process is as follows: the material feeding and receiving electric cylinder 202 and the material separating cylinder 203 first lower the empty tray into the narrow suspended belt conveyor 201, then the material separating cylinder 203 blocks the empty tray above, and then the lifting cylinder 205 lifts it up. Then the unloading robot 401 sorts the materials that have been photographed and inspected. OK products are put into the empty tray, and NG products are put into the belt conveyor.
