Description

Technical Field

[0001] This invention relates to the field of inspection device technology, specifically a visual inspection device for medical silicone parts. Background Technology

[0002] During the manufacturing process of medical silicone caps, a cross-shaped incision is typically cut into the top. This incision must meet specific dustproof and sealing performance requirements, thus demanding high processing precision. Due to the small gap in the incision, material adhesion is prone to occur after cutting. Therefore, inspection is necessary after the cutting process. Some silicone caps can be de-adhesiveted with just slight pressure. However, existing inspection equipment generally lacks corresponding processing mechanisms. For silicone caps with adhesion, secondary processing or manual intervention is still required, leading to reduced production efficiency and increased working hours.

[0003] Therefore, it is necessary to provide a device that can simultaneously eliminate adhesion during visual inspection to improve the overall processing efficiency and production automation level of silicone caps. Summary of the Invention

[0036] To eliminate the adhesion of silicone parts at the cut edges and ensure production efficiency and inspection quality, a visual inspection device was designed to eliminate silicone parts at the cut edges and provide comprehensive inspection. The specific solution is as follows:

[0037] Example 1

[0038] like Figure 1As shown, a visual inspection device for medical silicone parts includes a loading section 2, a pre-inspection processing section 3, a machine base 1, a specification inspection section 4 and a unloading section 5 mounted on the machine base 1.

[0039] The feeding section 2 is equipped with a hopper 201, and a feeding conveyor belt is provided at the bottom of the hopper 201 for conveying silicone parts A. Specifically, the feeding section 2 includes a hopper 201 and a feeding conveyor belt. The feeding conveyor belt includes a first feeding conveyor belt 202 and a second feeding conveyor belt 204. The first feeding conveyor belt 202 is located at the bottom of the hopper 201 and is inclined to convey the silicone parts A from the lower position to the second feeding conveyor belt 204. The first feeding conveyor belt 202 is equipped with an openable cover to prevent the product from falling out and to facilitate the operator to observe the internal conveying situation. The surface of the first feeding conveyor belt 202 is equipped with multiple raised baffles to ensure that the first feeding conveyor belt 202 lifts and feeds the silicone parts A.

[0040] The hopper 201 is located below the pre-inspection processing unit 3 and is used to load silicone part A products and receive products blown off from the pre-inspection processing unit 3. The first feeding conveyor belt 202 is connected to the second feeding conveyor belt 204 through the dropping channel 203. The dropping channel 203 is a closed structure with push-pull baffles on the outside of the channel. The discharge end of the first feeding conveyor belt 202 is located above the second feeding conveyor belt 204. In order to prevent products from falling outside at will, the dropping channel 203 needs to be set to restrict the falling direction. The discharge end of the second feeding conveyor belt 204 is connected to the feeding end of the feeding conveyor belt 301. The discharge end of the second feeding conveyor belt 204 is located above the feeding end of the feeding conveyor belt 301, so that products can fall to the feeding end of the feeding conveyor belt 301. Both the second feeding conveyor belt 204 and the feeding conveyor belt 301 are equipped with baffles to prevent products from falling.

[0041] The pre-inspection processing unit 3 is equipped with a feeding conveyor belt 301. The feeding conveyor belt 301 is equipped with a guide mechanism 302, a forward and reverse detection mechanism 303, a return mechanism and an extrusion mechanism 304 in sequence. The guide mechanism 302 is equipped with a retractable side pressure block 3022, which can apply slight side pressure to the product. The extrusion mechanism 304 is equipped with an extrusion plate 3047, which can extrude the cut of the silicone part A.

[0042] The guiding mechanism 302 includes a guide plate 3021 and a retractable side pressure block 3022. The guide plate 3021 is an arc-shaped plate and is located on one side of the feeding conveyor belt 301. After the silicone part A comes into contact with the arc-shaped plate, it is guided by the plate and moves towards one side of the feeding conveyor belt 301 in a straight line. The side pressure block 3022 is installed on the same side of the guide plate 3021. A clearance opening is provided on the guide plate 3021, and the side pressure block 3022 is installed in the clearance opening. The rear of the side pressure block 3022 is connected to a telescopic cylinder 4014. The telescopic movement of the cylinder controls the side pressure block 3022 to move back and forth, applying a slight force to the side of the silicone part A to squeeze it, thereby causing the cut of the silicone part A to break.

[0043] An air blowing component is also provided between the discharge direction of the guide mechanism 302 and the forward and reverse detection mechanism 303. In order to maintain a certain distance between the products during conveying, the silicone parts A that are arranged too densely will be blown back into the hopper 201.

[0044] The forward and reverse detection mechanism 303 includes a bracket installed on one side of the feeding conveyor belt 301 and a detection camera 4012. The detection camera 4012 is installed on the bracket. The conveying path of the silicone part A is located directly below the detection camera 4012. Specifically, the camera detects the silicone part A directly below it to detect whether the position of the silicone part A is upside down and whether the silicone part A is upright. An air blowing component is also provided between the forward and reverse detection mechanism 303 and the extrusion mechanism 304. If the silicone part A is in a fallen state, it will be blown back into the hopper 201 by the air blowing component.

[0045] The extrusion mechanism 304 includes symmetrically arranged side conveyor belts 3041 and extrusion plates 3047 disposed between the side conveyor belts 3041. A lead screw 3044 adjustment component is connected between the side conveyor belts 3041. The lead screw 3044 adjustment component includes a lead screw 3044, a slider 3045, an adjusting handwheel 3046, and a mounting frame 3043. The mounting frame 3043 is mounted on the feeding conveyor belt 301. Both ends of the lead screw 3044 are screwed to both ends of the mounting frame 3043. The slider 3045 is slidably connected to the mounting frame 3043. The adjusting handwheel 3046 is installed at one end of the lead screw 3044 and is used to adjust the spacing of the side conveyor belts 3041. One side conveyor belt 3041 is fixedly connected to the slider 3045. By rotating the adjusting handwheel 3046, the spacing between the two side conveyor belts 3041 can be adjusted to allow silicone parts A of different specifications to be transported from the side conveyor belts 3041. The two lateral conveyor belts 3041 pass through each other. One end of each lateral conveyor belt 3041 is connected to a servo motor 3042 for driving. The two servo motors 3042 are linked for control, so that the two lateral conveyor belts 3041 operate at the same speed. The operating speed of the two lateral conveyor belts 3041 is the same as that of the feeding conveyor belt 301, which can prevent the silicone part A from falling over. The extrusion plate 3047 is fixedly installed on the inside of one lateral conveyor belt 3041 and is used to extrude the cut of the silicone part A from the top to ensure that the cut is not stuck. The extrusion plate 3047 has a waist-shaped hole for height adjustment. The two ends of the extrusion plate 3047 adopt an arc transition design, so that the silicone part A can move more smoothly under the extrusion plate 3047. During the movement of the lateral conveyor belt 3041, the extrusion plate 3047 can extrude the cut on the top of the silicone part A to ensure that the cut on the silicone part A is completely broken.

[0046] The specification inspection unit 4 is equipped with multiple vision inspection cameras, which can perform visual inspection of silicone part A from multiple angles through a refractive plate.

[0047] The machine tool 1 is equipped with a conveyor turntable 101, and the specification inspection unit 4 is located around the conveyor turntable 101. A conveyor guide wheel is also provided between the conveyor turntable 101 and the feeding conveyor belt 301. The conveyor turntable 101 is a transparent turntable. The conveyor guide wheel is located in the discharge direction of the feeding conveyor belt 301. A servo motor 3042 is connected to the top of the conveyor guide wheel to control the rotation of the conveyor guide wheel. By rotating the conveyor guide wheel, the silicone part A on the feeding conveyor belt 301 can be smoothly guided and moved to the conveyor turntable 101. A servo drive motor is connected to the bottom of the conveyor turntable 101 to control the rotation of the conveyor turntable 101.

[0048] The specification inspection unit 4 includes a first inspection mechanism 401 and a second inspection mechanism 402 in a ring structure. The first inspection mechanism 401 is provided with a ring support 4011. The top of the ring support 4011 is also connected to a telescopic cylinder 4014, which can be used to control lifting. The ring support 4011 is located above the conveyor turntable 101. Multiple inspection cameras 4012 are set at equal angles on the ring support 4011. The multiple inspection cameras 4012 are installed on the ring support 4011 in two layers. An inclined refractive lens 4013 is provided directly below each inspection camera 4012. When the silicone part A moves to the direct under the ring support 4011, the multiple cameras can take pictures of the silicone part A from various angles at the same time through the refractive lens 4013 for image inspection, inspection of appearance, etc., to check for defects, etc.

[0049] The second inspection mechanism 402 is located around the conveyor turntable 101. The second inspection mechanism 402 includes an inspection camera 4012 located below the edge of the conveyor turntable 101. Since the conveyor turntable 101 is a transparent turntable, the inspection camera 4012 can perform visual inspection on the bottom of the silicone part A. The second inspection mechanism 402 also includes cameras located around the conveyor turntable 101 for inspecting the height, appearance and size of the silicone part A.

[0050] The unloading section 5 is provided with multiple unloading channels along the conveyor turntable 101. Specifically, the multiple unloading channels include a good product channel 501, a defective product channel 502 / 501, a defective product pending confirmation channel 503, and a reserved channel 504. The reserved channel 504 can be used for unloading in certain defective situations. Each unloading channel is equipped with an air blowing component at its inlet to facilitate blowing the silicone part A into the unloading channel. The air blowing component includes an air blowing rod 5013 and a connecting block for fixed connection with the corresponding unloading channel. The air blowing rod 5013 is installed at the front end of the connecting block and is connected to an external air supply device. The connecting block has a waist-shaped hole to adjust the distance between the air blowing rod 5013 and the inlet of the unloading channel, ensuring that the silicone part A is blown into the corresponding unloading channel. The good product channel 501 is designed with dual material flow channels 5011. Each channel is equipped with a pneumatically driven baffle. When the loading container below is full, another channel is opened, and the current channel is closed by the baffle descending.

[0051] Working principle:

[0052] The operator pours a batch of silicone parts A into the hopper 201. The first feeding conveyor belt 202 at the bottom of the hopper 201 starts, smoothly lifting the products from the bottom upwards.

[0053] After being transported to the top by the first feeding conveyor belt 202, the product falls through the unloading channel to the second feeding conveyor belt 204. The second feeding conveyor belt 204 then horizontally conveys the product to the feeding conveyor belt 301 of the cutting inspection section. External guards on each conveyor belt prevent products from accidentally falling off.

[0054] After the product enters the feeding conveyor belt 301 of the cut detection section, it first passes through the guide mechanism 302. The arc-shaped guide plate 3021 arranges the product towards one side of the feeding conveyor belt 301. The retractable side pressure block 3022, driven by the cylinder, slightly squeezes the side of the product to initially separate any possible cut adhesion.

[0055] Before entering the cut inspection, the air blowing component blows overly dense products back to the hopper 201, ensuring that each product enters the subsequent station at an appropriate distance and avoids mutual obstruction.

[0056] The product arrives below the positive / negative detection mechanism 303. The detection camera 4012 quickly captures images, and the intelligent image processing system determines in real time whether the product is upright. If it is identified as lying down, the air blowing component after that station is triggered to blow it back into the hopper 201 below.

[0057] Products that pass the initial inspection proceed to the extrusion mechanism 304. Based on product specifications, the lead screw 3044 is manually adjusted to match the spacing between the two side conveyor belts 3041 with the product width. The two side conveyor belts 3041 run synchronously and at the same speed as the main feeding conveyor belt 301, smoothly clamping the product as it passes through. During this process, the extrusion plate 3047, fixed to the inside of one side conveyor belt, slides across the top of the product, performing a secondary extrusion on the cut to ensure that any minor adhesions are completely broken.

[0058] The product is guided from the end of the feeding conveyor belt 301 by the rotating conveyor guide wheel and smoothly transferred to the transparent conveyor turntable 101.

[0059] When the product rotates with the turntable to directly below the first inspection mechanism 401, multiple inspection cameras 4012 arranged in multiple layers on the ring bracket 4011 work synchronously. The refractive lens 4013 paired with each camera enables the first inspection mechanism 401 to acquire 360° all-round images of the product's side circumference at different heights at one time, efficiently detecting appearance defects such as scratches, stains, and missing materials on the product surface.

[0060] Because the turntable is transparent, the second inspection mechanism 402 camera located below it can perform imaging inspection of the bottom of the product, while other cameras around the turntable are used to measure key parameters such as the product's height and outline dimensions.

[0061] The device's overall control system summarizes all data from the initial cut inspection, extrusion results, and comprehensive appearance and dimensional inspections, and makes a final judgment on each product, classifying them as good products, identifiable defective products, or uncertain products requiring re-inspection.

[0062] The product moves with the turntable to the corresponding feeding channel inlet, and the corresponding air blowing component is activated to blow the product into the designated channel, completing the sorting. The good product channel 501 adopts a dual-channel design. When the collection container under one channel is full, the pneumatic baffle is controlled to switch channels, achieving uninterrupted continuous feeding and ensuring smooth production.

[0063] The visual inspection device in this solution integrates feeding, pre-inspection and processing of cuts, multi-dimensional specification detection, and intelligent sorting and unloading. It is highly efficient and automated, reduces manual intervention, and improves inspection efficiency.

[0064] The hopper 201 is not only used for initial feeding, but also for receiving silicone parts A that have been rejected by the air-blown components, such as those that are upside down or too densely packed, so as to achieve recycling and reprocessing.

[0065] The enclosed feeding conveyor belt channel enables the directional transfer of products from the first feeding conveyor belt 202 to the second feeding conveyor belt 204, and then to the feeding conveyor belt 301, avoiding problems such as jamming, damage or misalignment caused by products falling randomly at the transfer point.

[0066] Before inspection, the silicone part A is arranged and slightly pressed by the arc plate of the guide mechanism 302 and the retractable side pressure block 3022. This actively promotes the breaking of possible cut adhesions, creating a more consistent and easier-to-judge state for subsequent visual inspection, thereby improving the accuracy and reliability of the inspection.

[0067] During the feeding process, products that are too densely packed are thinned out to ensure that each silicone part A passes through the detection point at an appropriate interval, avoiding mutual obstruction and ensuring imaging and detection quality.

[0068] The movement of one side conveyor belt is driven by the lead screw 3044 adjustment component, which can precisely adjust the spacing between the two side conveyor belts 3041 to accommodate silicone parts A of different specifications and sizes, thereby improving the versatility of the equipment.

[0069] Two side conveyor belts 3041 are linked and controlled by servo motors 3042, and their speed is synchronized with the main feeding conveyor belt 301, ensuring that the silicone part A is stable when passing through, without the risk of being pulled or falling over. The extrusion sheet 3047 can be height adjusted, and both ends are designed with arc transition, which can supplement the extrusion of the cut without damaging the product, ensuring complete separation of adhesion, and the processing method is gentler and more reliable.

[0070] The first inspection unit 401 uses a ring bracket 4011 with multi-layered cameras and tilted refractive lenses 4013. When the silicone part A passes through once, images of its various circumference angles can be acquired at once, resulting in high inspection efficiency and no blind spots.

[0071] A transparent conveyor turntable 101 is used, allowing the camera located below it to directly perform visual inspection of the bottom of the silicone part A. Combined with other inspection cameras 4012 around it for detecting height and appearance dimensions, comprehensive inspection of all directions and key dimensional parameters can be achieved.

[0072] The unloading system does not have separate channels for good products, defective products, products awaiting confirmation, or reserved channels 504, which meets the product classification needs of complex production sites. Each unloading channel entrance is equipped with an independently adjustable air blowing component for accurate blowing. The good product channel 501 adopts a dual-channel design with pneumatic baffles, which can automatically switch channels when the collection container below is full, achieving continuous collection without stopping the machine and improving the overall continuous operation capability and production efficiency of the equipment.

[0073] Example 2

[0074] In this embodiment, the structure of the device is basically the same as that of Embodiment 1. The difference is that an air curtain nozzle is added above each refractive lens 4013 of the annular support 4011 to periodically blow out clean airflow to prevent dust from adhering to the refractive lens 4013 and affecting the test results.
