Description

Technical Field

[0001] This utility model relates to the field of acrylic injection molding technology, and in particular to a visual inspection mechanism for the appearance of all relays. Background Technology

[0002] Full visual inspection of relays is a technology that uses machine vision systems (cameras, light sources, algorithms, etc.) to 100% automatically detect appearance defects in each relay. Its core goal is to replace manual visual inspection, achieve more accurate defect identification, higher inspection efficiency, and standardized quality judgment. It is widely used in fields with extremely high requirements for relay reliability, such as automotive electronics, industrial control, and smart homes.

[0003] In the existing technology, after the relay arrives at the inspection station via a belt conveyor, a positioning sensor triggers a camera to take a picture, and an image processing system is used to compare the "standard relay image" with the "actually captured image" to identify defects.

[0004] However, the relays are photographed and identified during the conveyor belt operation. If the relays move, the photographed images will be unclear. When the image processing system compares the images, it will mistakenly identify normal relays as defective ones, resulting in a misjudgment. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a visual inspection mechanism for the appearance of all relays.

[0006] The technical solution of this utility model: A relay full appearance visual inspection mechanism, including a housing, with a material inlet on the left side of the housing, and further including: The detection and positioning mechanism includes a conveyor belt for a conveyor relay. The conveyor belt passes through the feed inlet and is fixedly installed inside the machine housing. A third cylinder is fixedly installed on one side of the conveyor belt. A buffer spring is fixedly installed at the end of the third cylinder. A top block is fixedly installed at the end of the buffer spring. A fence mechanism is provided on the other side of the belt conveyor, and a top detection camera located directly above the top block is fixedly installed inside the housing.

[0007] Optionally, the fence mechanism includes a first cylinder and a second cylinder, both of which are fixedly installed on the side of the belt conveyor away from the third cylinder, and there is a gap between the first cylinder and the second cylinder.

[0008] Optionally, the first cylinder, the third cylinder, and the second cylinder are distributed sequentially along the belt line, and the rods of the first cylinder and the second cylinder extend completely to surround the relay.

[0009] Optionally, a side detection mechanism is provided inside the housing. The side detection mechanism includes a fixed frame, on which a transfer clamp is slidably connected. The transfer clamp is located on the right extension line of the belt conveyor.

[0010] Optionally, multiple transfer clamps are provided and are distributed in a straight line along the fixed frame. The multiple fixed frames are connected to each other, and the transfer clamps pick up the relays.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0025] Example: This utility model proposes a visual inspection mechanism for the appearance of all relays, such as... Figures 1 to 4 As shown, the machine includes a housing 1, and a feed inlet 2 is provided on the left side of the housing 1. A relay is inserted through the feed inlet 2.

[0026] The housing 1 is equipped with a detection and positioning mechanism 3. The detection and positioning mechanism 3 includes a conveyor belt 31 for conveying relays. A fence mechanism is provided on one side of the conveyor belt 31. The fence mechanism includes a first cylinder 32 and a second cylinder 33. Both the first cylinder 32 and the second cylinder 33 are fixedly installed on the side of the conveyor belt 31.

[0027] A photoelectric sensor is fixedly installed between the second cylinder 33 and the first cylinder 32. In the prior art, there is a design that controls the extension of the cylinder through the photoelectric sensor. When the photoelectric sensor detects that the relay has entered between the first cylinder 32 and the second cylinder 33, the rods of the first cylinder 32 and the second cylinder 33 extend to surround the relay, thereby intercepting the relay between the first cylinder 32 and the second cylinder 33. At the same time, the second cylinder 33 intercepts the relay behind it to avoid affecting the image recognition of the relay located between the first cylinder 32 and the second cylinder 33.

[0028] In one embodiment, the belt conveyor 31 passes through the feed inlet 2 and is fixedly installed inside the housing 1. A third cylinder 34 is fixedly installed on the other side of the belt conveyor 31. A buffer spring 35 is fixedly installed at the end of the third cylinder 34, and a top block 36 is fixedly installed at the end of the buffer spring 35.

[0029] The first cylinder 32, the third cylinder 34, and the second cylinder 33 are sequentially distributed along the belt conveyor 31. The third cylinder 34 extends to move the top block 36, thereby fixing the relay to the inside of the belt conveyor 31. The first cylinder 32 and the second cylinder 33 cooperate to ensure that the top block 36 can stably hold the belt conveyor 31 after the third cylinder 34 extends. A buffer spring 35 acts as a buffer to prevent the top block 36 from damaging the product.

[0030] Furthermore, a top inspection camera 4 is fixedly installed inside the housing 1, located directly above the top block 36. A cylinder with a light source mounted at its end is fixedly installed on the side of the top inspection camera 4. During operation, the cylinder retracts and the light source is brought close to the product to ensure effective photographic inspection. During inspection and maintenance, the cylinder extends, increasing the gap between the light source and the product for easier equipment maintenance.

[0031] This invention intercepts the relay using a first cylinder 32 and a second cylinder 33. Under the influence of the conveyor belt 31, the end of the relay abuts against the first cylinder 32. At this time, the third cylinder 34 extends to press the top block 36 against the relay and fix the relay inside the conveyor belt 31, preventing the relay from shaking due to the conveyor belt 31. This achieves the interception and positioning of the relay, preventing the relay from moving during the image recognition process and affecting the accuracy of image recognition.

[0032] As one implementation method, such as Figure 3 and Figure 5 As shown, a side detection mechanism 5 is provided inside the housing 1. The side detection mechanism 5 includes a fixed frame 51. A transfer clamp 52 is slidably connected to the fixed frame 51. The transfer clamp 52 is located on the right end extension line of the belt 31. Multiple transfer clamps 52 are provided and are distributed in a straight line along the fixed frame 51. The multiple fixed frames 51 are connected to each other. The transfer clamp 52 clamps the relay.

[0033] The relay is picked up by the transfer clamp 52 and transferred sequentially. The transfer clamp 52 reciprocates. The transfer clamp 52 in the first position picks up the relay and moves it to the initial position of the transfer clamp 52 in the second position. The clamp is then released. The transfer clamp 52 in the first position then resets. Then the transfer clamp 52 in the second position picks up the relay and moves it to the initial position of the transfer clamp 52 in the third position.

[0034] A side inspection camera 53 is fixedly installed inside the housing 1. The side inspection camera 53 is located on the side in the direction of relay transportation. Two side inspection cameras 53 are set. The two side inspection cameras 53 are staggered by multiple fixed frames 51, so that the relay passes through the two side inspection cameras 53 one after another. The side inspection camera 53 has an automatic focus adjustment function.

[0035] As one implementation method, such as Figure 6 and Figure 7 As shown, a sorting mechanism 6 is provided inside the housing 1. The sorting mechanism 6 includes a conveyor frame 61 fixedly installed inside the housing 1. The conveyor frame 61 is located at the end extension line of the belt line 31. A limit block is fixedly installed at the end of the conveyor frame 61. A multi-groove plate 62 is fixedly installed on the side of the conveyor frame 61. Both the conveyor frame 61 and the multi-groove plate 62 extend out from inside the housing 1.

[0036] A gantry frame 63 is fixedly installed inside the housing 1. A sorting fixture 64 for picking up relays is slidably connected to the side of the gantry frame 63. The sorting fixture 64 slides on the gantry frame 63 to move damaged relays onto the multi-slot plate 62.

[0037] The multi-slot plate 62 has multiple horizontal slots, and the damaged locations of the relays on each horizontal slot are different. The bottom of the conveyor frame 61 is hollowed out, and a bottom detection camera 65 is fixedly installed on the bottom of the conveyor frame 61. The bottom detection camera 65 identifies the relays and identifies the damaged locations of the relays. Based on the damage of different parts, they are placed on the corresponding horizontal slots on the multi-slot plate 62.

[0038] This invention utilizes a multi-slot plate 62 with multiple horizontal slots, each with a different location of relay damage. A bottom detection camera 65 identifies the relays and determines their location of damage. A sorting fixture 64 then places the damaged relays onto the corresponding horizontal slots on the multi-slot plate 62, thus classifying the damaged relays for subsequent repair.

[0039] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
