Description

Technical Field

[0001] This utility model relates to the field of automated testing equipment technology, and in particular to an automated transmission device for an image screening machine. Background Technology

[0002] As a key piece of equipment for quality control in the production of precision parts, the image sorting machine uses a horizontally placed transparent glass disc as a transport carrier. The continuous rotation of the transparent glass disc transports the products to be inspected to the image acquisition area in sequence. An industrial camera set above or below the transparent glass disc takes pictures of the products. Then, the image processing algorithm analyzes and judges the size and appearance defects of the products, and sorts the products into the qualified product area or the waste area according to the judgment results.

[0003] However, with the increasing demands for testing efficiency in modern industry, the rotation speed of the transparent glass disk needs to be significantly increased. When the transparent glass disk is rotating at high speed, the product to be tested placed on the smooth surface of the transparent glass disk is easily subjected to centrifugal force and tends to move outward. This causes the product to slide relative to the surface of the transparent glass disk, shift its position, or even shake slightly. The tiny displacement of the product at the moment of imaging will cause the image captured by the camera to be blurry or the feature point positioning to be inaccurate, which in turn will lead to misjudgment or missed judgment by the image screening system, seriously affecting the accuracy of the test results and the stability of the screening work. In addition, existing rejection mechanisms often rely solely on high-pressure airflow to blow out defective products. For some defective products that are tightly attached to the surface of the transparent glass disk or are heavy, a single pneumatic blowing force is not enough to ensure complete rejection, which can easily cause screening failure.

[0004] Therefore, this utility model proposes an automated transmission device for an image screening machine to address the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems in the prior art, the products to be inspected by the image sorting machine are easily affected by centrifugal force during high-speed rotation inspection, resulting in blurred images, and qualified products are easily dropped and hit the rigid inner wall of the recycling container during recycling, causing damage to the surface of precision products. The present invention aims to provide an automated transmission device for the image sorting machine with an improved structure, which can fix the products by pneumatic negative pressure adsorption and use an adjustable buffer mechanism to receive the products.

[0006] This utility model provides an automated transmission device for an image sorting machine, including a sorting machine housing, a feeding seat fixedly connected to the outer wall of the sorting machine housing, a rotating seat fixedly connected to the middle of the inner wall of the sorting machine housing, a transparent ring fixedly connected to the top of the rotating seat, a detector fixedly connected to the inner wall of the sorting machine housing, a recycling seat fixedly connected to the inner wall of the sorting machine housing, and a recycling bin fixedly connected to the inner wall of the sorting machine housing.

[0007] An integrated air valve is fixedly connected to the center of the top surface of the rotating seat. A connecting air pipe is fixedly connected to the inner wall of the integrated air valve. A connecting plate is connected to the end of the connecting air pipe away from the integrated air valve. An air blowing pipe is connected to the side of the connecting plate away from the connecting air pipe. The port of the air blowing pipe faces the surface of the transparent ring and is used to adsorb and fix the product body that falls onto the surface of the transparent ring or to blow it away.

[0008] Furthermore, a sliding cylinder is fixedly connected to the side of the connecting plate away from the connecting air pipe. An ejector rod is slidably connected inside the sliding cylinder. The ejector rod is used to slide inside the sliding cylinder and eject the product body outward. The output port of the conveying seat penetrates the rear side of the inner wall of the screening machine housing and extends to the top of the transparent ring.

[0009] Preferably, a buffer plate is slidably connected to the inner wall of the recycling seat, an electric push rod is fixedly connected to the bottom of the inner wall of the recycling seat, a rotating shaft is rotatably connected to the bottom of the buffer plate, and the top end of the electric push rod is fixedly connected to the rotating shaft. The electric push rod is used to drive the buffer plate to move up and down within the recycling seat and to drive the buffer plate to tilt through the difference in extension and retraction of the electric push rods on both sides.

[0010] Preferably, the outer wall of the recycling seat has a discharge port on the rear side, and the outer wall of the discharge port is connected to a qualified port. When the buffer plate is tilted, it is used to guide the main body of the product to the discharge port and slide it into the qualified port.

[0011] Preferably, a buffer pad is fixedly connected to the inner wall of the recycling seat. The buffer pad is located in the area of ​​the recycling seat where the product body is received, in order to reduce direct contact between the product body and the inner wall of the recycling seat.

[0012] Preferably, a limiting plate is fixedly connected to the inner wall of the recycling seat. The limiting plate is located above the buffer plate and is used to limit the maximum distance the buffer plate can rise.

[0013] Preferably, an angled ring is fixedly connected to the outer wall of the transparent ring, and the angled ring is used to assist in positioning the product body on the transparent ring or to prevent slippage.

[0014] Preferably, the inner wall of the recycling bin is connected to a waste inlet, the position of which corresponds to the position where the ejector rod ejects the product body, so that the rejected product body can enter the recycling bin.

[0015] Preferably, the sliding direction of the ejector rod is perpendicular to the axial direction of the integrated air valve.

[0016] Preferably, the output port of the feed seat faces the surface of the transparent ring.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problem in the prior art where the product is easily shaken or displaced by centrifugal force during high-speed transmission in image screening machines by setting an integrated air valve on the top of the rotating seat in conjunction with the connecting air pipe and the blowing air pipe. It utilizes the principle of negative pressure adsorption to fix the main body of the product on the surface of the transparent ring. This achieves the effect of ensuring that the product is absolutely fixed in position during the detection process and significantly improving the clarity of image detection and the accuracy of screening.

[0018] 2. This utility model solves the problem in the prior art where qualified products are directly dropped and rigidly collide with the inner wall of the recycling container during the recycling process, causing surface damage, by setting a buffer pad on the inner wall of the recycling seat and a liftable and tiltable buffer plate driven by an electric push rod. It achieves the effect of flexible product reception and stable export with low drop, and effectively avoids damage to precision parts due to secondary collisions. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model. Example

[0022] Please refer to Figures 1 to 6 This utility model provides an automated transmission device for an image screening machine, which aims to solve the problems in the prior art where the main body of the product 6 is easily shaken or displaced by centrifugal force during high-speed transmission of images, and is easily damaged by collision during the recycling of qualified products.

[0023] Please refer to Figure 1 and Figure 2 The automated transmission device of the image screening machine includes a screening machine housing 1, a transport mechanism 2, and a buffer mechanism 3. The screening machine housing 1 serves as the mounting base for the entire device. The material conveying seat 5 is fixedly connected to the outer wall of the screening machine housing 1. The material conveying seat 5 is used to transport the product body 6 into the screening machine housing 1. The output port of the material conveying seat 5 penetrates the rear side of the inner wall of the screening machine housing 1, so that the product body 6 can fall smoothly onto the internal transmission structure.

[0024] A rotating seat 203 is fixedly connected to the middle of the inner wall of the screening machine housing 1. A transparent ring 201 is fixedly connected to the top of the rotating seat 203. The transparent ring 201 is used to support and transport the product body 6. An angled ring 202 is fixedly connected to the outer wall of the transparent ring 201. The angled ring 202 is used to position and limit the product body 6 on the transparent ring 201, preventing the product body 6 from being thrown out due to rotation or centrifugal force.

[0025] The inner wall of the screening machine housing 1 is also fixedly connected to a detector 4. The detector 4 is used to perform image detection and quality screening on each product body 6 that rotates with the transparent ring 201. The inner wall of the screening machine housing 1 is fixedly connected to a recycling seat 302 and a recycling box 8. The recycling seat 302 is used to receive and buffer qualified product bodies 6, and the recycling box 8 is used to receive rejected defective products.

[0026] An integrated air valve 204 is fixedly connected to the center of the top surface of the rotating seat 203. A connecting air pipe 206 is fixedly connected to the inner wall of the integrated air valve 204. A connecting plate 205 is connected to the end of the connecting air pipe 206 away from the integrated air valve 204. An air blowing pipe 207 is connected to the side of the connecting plate 205 away from the connecting air pipe 206. The port of the air blowing pipe 207 faces the surface of the transparent ring 201. When the integrated air valve 204 generates negative pressure, it is used to adsorb and fix the product body 6 on the surface of the transparent ring 201, so as to ensure that the product body 6 is fixed in position and does not shake during high-speed rotation, thereby improving the detection accuracy of the detector 4.

[0027] A slide cylinder 209 is also fixedly connected to the side of the connecting plate 205 away from the connecting air pipe 206. An ejector rod 208 is slidably connected inside the slide cylinder 209. The ejector rod 208 is used to cooperate with the air blowing pipe 207 to eject the product body 6 that is judged to be defective outward when the integrated air valve 204 generates positive pressure, so as to send it into the recycling box 8. The inner wall of the recycling box 8 is connected to the waste port 7. The position of the waste port 7 corresponds to the rejection position of the ejector rod 208 and the air blowing pipe 207 in the circumferential direction.

[0028] Please refer to Figure 3 , Figure 5 and Figure 6 The inner wall of the recycling seat 302 is slidably connected to a buffer plate 306. The buffer plate 306 serves as the main carrier for receiving the main body of the product 6. Two sets of rotating shafts 305 are provided at the bottom of the buffer plate 306. The rotating shafts 305 are rotatably connected to the buffer plate 306. Two sets of electric push rods 307 are fixedly connected to the bottom of the inner wall of the recycling seat 302. The top of the electric push rods 307 is fixedly connected to the rotating shafts 305. Through this cooperative structure, the electric push rods 307 can not only drive the buffer plate 306 to move up and down as a whole in the recycling seat 302 to adjust the dropping height, but also make the buffer plate 306 rotate around the rotating shafts 305 and tilt by controlling the difference in extension and retraction of the electric push rods 307 on both sides.

[0029] A buffer pad 303 is fixedly connected to the inner wall of the recycling seat 302. The buffer pad 303 is located in the upper feeding area of ​​the recycling seat 302 and is used to provide flexible contact when the product body 6 enters the recycling seat 302 to avoid hard collision. A limiting plate 304 is also fixedly connected to the upper part of the inner wall of the recycling seat 302. The limiting plate 304 is located above the stroke of the buffer plate 306 and is used to limit the maximum displacement distance of the buffer plate 306. A discharge port 308 is opened on the rear side of the outer wall of the recycling seat 302. The outer wall of the discharge port 308 is connected to the qualified port 301. When the buffer plate 306 is tilted towards the discharge port 308, the buffer plate 306 and the discharge port 308 form a continuous sliding channel to ensure that the product body 6 can slide smoothly into the qualified port 301.

[0030] In a preferred embodiment, an angled ring 202 is fixedly connected to the outer wall of the transparent ring 201. The inclined surface of the angled ring 202 faces the inner wall of the screening machine housing 1, and the edge of the angled ring 202 is higher than the surface of the transparent ring 201. The angled ring 202 is used to assist the product body 6 in positioning on the transparent ring 201 to prevent slippage. The detector 4 is set on the inner wall of the screening machine housing 1 and located directly above the moving path of the transparent ring 201. The detector 4 is used to capture vertical images of the product body 6 as it rotates with the transparent ring 201.

[0031] As another preferred embodiment, a slide cylinder 209 is fixedly connected to the side of the connecting plate 205 away from the connecting air pipe 206. An ejector rod 208 is slidably connected inside the slide cylinder 209. The sliding direction of the ejector rod 208 is perpendicular to the axis of the integrated air valve 204. A waste port 7 is connected to the inner wall of the recycling box 8. The position of the waste port 7 corresponds precisely to the ejection position of the ejector rod 208 in the circumferential direction, ensuring that the main body 6 of the rejected product falls accurately into the recycling box 8.

[0032] As a further preferred embodiment, a limiting plate 304 is fixedly connected to the inner wall of the recycling seat 302. The limiting plate 304 is located above the buffer plate 306 and a buffer gap is reserved between the two. The limiting plate 304 is used to physically limit the highest rising position of the buffer plate 306. A buffer pad 303 is fixedly connected to the inner wall of the recycling seat 302. The buffer pad 303 is located in the area of ​​the recycling seat 302 that receives the product body 6. The buffer pad 303 is made of elastic rubber material and is used to absorb the impact kinetic energy of the product body 6.

[0033] Working principle: When using the automated transmission device of the image screening machine, the conveying seat 5 is fixedly connected to the outer wall of the screening machine housing 1. The conveying seat 5 transports the product body 6 into the screening machine housing 1. The product body 6 falls to the top of the transparent ring 201. The rotating seat 203 drives the transparent ring 201 to rotate the product body 6. The detector 4 performs image detection on the product body 6. The integrated air valve 204 generates negative pressure. The negative pressure is transmitted to the blowing pipe 207 through the connecting air pipe 206 and the connecting plate 205. The blowing pipe 207 generates suction to adsorb the product body 6 onto the surface of the transparent ring 201, so that the product body 6 remains in a fixed position during rotation, preventing the product body 6 from being thrown out due to centrifugal force and reducing shaking during detection. When detector 4 detects that product body 6 is defective, integrated air valve 204 drives gas into connecting air pipe 206. After passing through connecting plate 205, the gas enters blowing pipe 207 to blow out product body 6. At the same time, the gas pushes ejector rod 208 to slide outward in slide cylinder 209. Ejector rod 208, in conjunction with the gas, pushes product body 6 outward, so that product body 6 enters recycling box 8 through waste port 7. When detector 4 detects that product body 6 is a qualified product, product body 6 is sent to the recycling seat 302. The buffer pad 303 reduces the collision when product body 6 comes into contact with recycling seat 302. Product body 6 falls onto buffer plate 306. Electric push rod 307 retracts, causing buffer plate 306 to move downward. The electric push rod 307 on one side of the discharge port 308 retracts a longer distance downward than the electric push rod 307 on the other side, causing buffer plate 306 to tilt towards discharge port 308. Product body 6 slides along buffer plate 306 into discharge port 308 and qualified port 301. Limiting plate 304 limits the maximum distance of buffer plate 306, thereby reducing the probability of damage to product body 6.
