Description

Technical Field

[0001] This invention belongs to the field of rubber product manufacturing technology, and particularly relates to an extrusion device. Background Technology

[0002] The new energy vehicle industry is experiencing rapid development, and the application scenarios for rubber products have also changed significantly. Rubber products directly affect vehicle safety and performance, leading to increasingly stringent requirements. During production, rubber products often suffer from defects such as insufficient rubber, gaps, mold contamination, adhesion, breakage, and cracking. Ordinary full-inspection machines can only perform visual inspections on the products based on their original shape. However, if cracks or microcracks are present, these defects, which require alteration of the original shape to become apparent, will be missed and allowed to flow out as good products, affecting sealing and insulation, and increasing safety risks. To detect cracked or microcracked products, extrusion equipment alters the original shape of the product to create the appearance of cracks or microcracks. Visual inspection then verifies the integrity of the product, identifies defective products, reduces the risk of leakage, and thus enhances the safety of new energy vehicles.

[0003] The existing extrusion equipment has the following problems:

[0004] 1. Slow detection efficiency:

[0005] 1) The extrusion disc needs to extrude and rotate 360° one by one to achieve multi-directional detection, but when the outer diameter of the product is large, it will take too long to extrude a single product, resulting in slow efficiency.

[0006] 2) The glass disc rotates at a constant speed, and the products are far apart, resulting in a long arrival time and slow efficiency.

[0007] 3) The extrusion disc moves slowly. After the product is in place, the extrusion disc starts to move. The start and end times cause the glass disc to remain stationary, resulting in slow overall operation. Summary of the Invention

[0008] The purpose of this invention is to provide an extrusion device to solve the problems existing in the prior art.

[0009] To achieve the above objectives, the present invention provides the following solution: The present invention provides an extrusion device, including a conveyor belt, one end of which is connected to an elevator. A material storage mechanism is provided above the conveyor belt away from the elevator. A guide wheel is provided on one side of the material storage mechanism, and a first connecting frame is provided on one side of the guide wheel. A glass tray for placing products is provided on the first connecting frame. An extrusion detection mechanism and an optical fiber sensor are provided above the glass tray. The extrusion detection mechanism includes extrusion discs symmetrically arranged above the glass tray. The extrusion detection mechanism also includes a detection part. The glass tray is connected to a product outlet.

[0010] Optionally, the material storage mechanism includes a second connecting frame disposed above the conveyor belt. The second connecting frame has front and rear baffles on one side and front and rear baffle adjusting screws on the second connecting frame. The front and rear baffle adjusting screws are induced to the front and rear baffles. The conveyor belt has left and right baffles on the side near the front and rear baffles, and the left and right baffles are induced to the left and right baffle adjusting screws.

[0011] Optionally, a first connecting seat is fixedly connected to the top surface of the front and rear baffles near the guide wheel. An upper and lower baffle adjusting screw is threaded onto the first connecting seat. The upper and lower baffles are drivenly connected to the upper and lower baffles, and the upper and lower baffles are located above the conveyor belt.

[0012] Optionally, the fiber optic sensor is located between the glass disk and the article.

[0013] Optionally, the distance between the two extrusion discs is less than the diameter of the article.

[0014] Optionally, the detection unit includes a light source fixed to the bottom of the first connecting frame, a prism above the light source, a first camera below the light source, and a plurality of second cameras above the light source.

[0015] Optionally, the second camera is located above the glass disk and is driven by a stepper motor, which is fixedly connected to the first connecting frame.

[0016] Optionally, the export of the product includes OK export and NG export.

[0017] This invention discloses the following technical effects: The elevator lifts the products onto the conveyor belt, where they enter the storage mechanism for orderly feeding. After passing through the storage mechanism, the products enter the glass tray. Information is provided by fiber optic sensors to feedback the distance between the products, triggering the movement of the conveyor belt and the glass tray, changing the running speed, accelerating the movement of the products to the extrusion tray position, reducing waiting time, and improving efficiency. The extrusion position is determined by the outer diameter of the product, and the distance between the two extrusion trays is less than the diameter of the product, allowing the product to be extruded and changed from its original circular shape. When the machine starts, the extrusion tray directly reaches the extrusion position and rotates continuously. When the product reaches the edge of the extrusion tray, it will be carried into the extrusion position with the rotation of the tray and detected. After the detection is completed, the glass tray rotates and drives the product towards the OK / NG exit.

[0018] This invention features a material storage mechanism that allows for intermittent feeding of products while simultaneously replenishing materials in a timely manner, thus accelerating the feeding speed. A fixed extrusion disc reduces the opening and closing time of the disc, increasing the efficiency of individual product inspection. Furthermore, a fiber optic sensor transmits information to provide feedback on the distance between products, enabling variable-speed operation, reducing interval differences, and improving overall efficiency.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Reference Figures 1 to 3 As shown, this embodiment provides an extrusion device, including a conveyor belt 1, one end of which is connected to an elevator 2. A material storage mechanism is provided above the conveyor belt 1 away from the elevator 2. A guide wheel 3 is provided on one side of the material storage mechanism, and a first connecting frame 4 is provided on one side of the guide wheel 3. A glass tray for placing products is provided on the first connecting frame 4. An extrusion detection mechanism and an optical fiber sensor 6 are provided above the glass tray. The extrusion detection mechanism includes extrusion plates 7 symmetrically arranged above the glass tray. The extrusion detection mechanism also includes a detection part. The glass tray is connected to a product outlet.

[0028] Elevator 2 lifts the products onto conveyor belt 1. The products enter the storage mechanism on conveyor belt 1, which sorts and feeds the products. After passing through the storage mechanism, the products enter the glass tray. Information is provided by fiber optic sensor 6, which feeds back the distance between the products and triggers the movement of conveyor belt 1 and glass tray, changing the running speed and speeding up the movement of the products to the extrusion plate 7, reducing waiting time and improving efficiency. The extrusion position is determined by the outer diameter of the product. The distance between the two extrusion plates 7 is less than the diameter of the product, so that the product can be extruded to change its original circular shape. When the machine starts, the extrusion plate 7 directly reaches the extrusion position. The extrusion plate 7 rotates continuously. When the product reaches the edge of the extrusion plate 7, it will be carried into the extrusion position with the rotation of the plate. It will follow the rotation for detection. After the detection is completed, the glass tray rotates and drives the product to OK outlet 21 / NG outlet 22.

[0029] This invention enables intermittent feeding of products by setting up a material storage mechanism, while also allowing for timely replenishment of materials, thereby accelerating the feeding speed; the extrusion plate 7 has a fixed extrusion position, reducing the opening and closing time of the extrusion plate 7 and accelerating the detection efficiency of individual products; and the fiber optic sensor 6 transmits information to feedback the distance between products, enabling variable speed operation, reducing the time difference between intervals, and accelerating the overall efficiency.

[0030] The design is further optimized so that the material storage mechanism includes a second connecting frame 8 set above the conveyor belt 1. A front and rear baffle 9 is provided on one side of the second connecting frame 8. A front and rear baffle adjusting screw 10 is provided on the second connecting frame 8. The front and rear baffle adjusting screw 10 is connected to the front and rear baffle 9 in a transmission connection. A left and right baffle 11 is provided on the side of the conveyor belt 1 close to the front and rear baffle 9. The left and right baffle 11 is connected to the left and right baffle adjusting screw 12 in a transmission connection.

[0031] The front and rear baffles 9 are used to control the spacing of the feeding channels. The spacing is controlled to be the size of the product diameter so that the products can be fed one by one. The left and right baffles 11 are used to adjust the distance between them and the guide rollers 3 so that the spacing is smaller than the product diameter. When the products pass through, they will be slightly squeezed.

[0032] In a further optimized design, a first connecting seat 13 is fixedly connected to the top surface of the front and rear baffles 9 near the guide wheel 3. An upper and lower baffle adjusting screw 14 is threaded onto the first connecting seat 13. The upper and lower baffle adjusting screw 14 is drivenly connected to the upper and lower baffles 15, which are located above the conveyor belt 1.

[0033] The upper and lower baffles 15 are used to adjust the distance between the conveyor belt 1 and the upper and lower baffles 15 so that the distance is the overall height of the product, allowing the product to be fed one by one, and preventing the accumulation and overlapping of materials from entering the flow channel.

[0034] Rotating the left and right baffles adjusts the screw 12, which moves the left and right baffles 11. This adjusts the distance between the left and right baffles 11 and the guide wheel 3. The distance is smaller than the outer diameter of the product, which buffers the product extrusion. The rotation of the glass disc and the guide wheel 3 causes the product to be micro-extruded and fed onto the glass disc. The resistance of the guide wheel 3 and the left and right baffles 11 causes the product to be fed at intervals. The rear flow channel can buffer the material and play a replenishing role, which can replenish the material in time and reduce the waiting time for sparse products.

[0035] The design was further optimized so that fiber optic sensor 6 is located between the glass disk and the product.

[0036] Using infrared light sensing, the position of the optical fiber is adjusted to be between the height of the glass disk and the product. The optical fiber is triggered when the product passes through.

[0037] The design was further optimized so that the distance between the two extrusion discs 7 was less than the diameter of the product.

[0038] The extrusion disc 7 consists of two aluminum alloy discs used for extruding products. The opening and closing time of the extrusion disc 7 is 2 seconds per piece. The fixed linkage of the extrusion disc 7 reduces the opening and closing time, which can reduce the time of each product by 2 seconds, greatly improving the overall efficiency.

[0039] The scheme is further optimized. The detection unit includes a light source 16 fixed to the bottom of the first connecting frame 4, a prism 17 above the light source 16, a first camera 18 below the light source 16, and multiple second cameras 19 above the light source 16.

[0040] In a further optimized design, the second camera 19 is located above the glass disk and is driven by a stepper motor 20, which is fixedly connected to the first connecting frame 4.

[0041] Light source 16 uses a colored light source 16 to illuminate the product, making it clearly distinguishable from defects when photographed by the first camera 18 and the second camera 19, facilitating defect detection. Through reflection by prism 17, the inner and outer sides of the product are uniformly photographed above the glass disk, and the lens captures images of the product through reflected light. The three second cameras 19 at the top are the outer camera (leftmost), the upper surface camera (middle), and the inner camera (rightmost). A motor controls the screw to move the second cameras 19 up and down for focusing. The focusing distance is adjusted according to the different outer diameters of each product to achieve uniformity. The lens rotates 180°, and each of the four cameras takes seven photos, covering the entire product, accelerating the extrusion speed and improving efficiency. Automatic focusing reduces the instability of manual focusing, and prism 17 reduces the influence of refraction through the glass disk, reducing the false judgment rate.

[0042] The plan has been further optimized, with product exports including OK export 21 and NG export 22. Qualified products will be exported through OK export 21, while non-qualified products will be exported through NG export 22.

[0043] The original inspection system used six cameras, one for the upper surface, one for the lower surface, two for the inner surface, and two for the outer surface. While each camera could capture images showing crack defects, the focus of each camera needed to be readjusted every time a product was changed, making it impossible to maintain consistent sharpness.

[0044] Currently, there are four inspection cameras: one for the upper surface, one for the lower surface, one for the inner side, and one for the outer side. After readjusting the light source, images captured by each camera can detect defects. Centralized processing of the four cameras accelerates processing efficiency and improves overall machine performance.
