Description

Technical Field

[0001] This application relates to the technical field of part screening equipment, and in particular to a needle selection device. Background Art

[0002] In the production process of carbon fiber preforms, the needling technique is an important three-dimensional forming method. This technique needles carbon fiber bundles with needles to form a uniformly distributed network structure in three-dimensional space. However, as the production process progresses, the needles gradually lose their original performance due to wear, breakage, etc., thus affecting product quality.

[0003] This process requires a large amount of needles, and the degree of loss varies. To ensure product quality, needles that have been used to a certain extent need to be eliminated. Among the needles that have been eliminated, the degree of loss is inconsistent, and there is a huge waste in this process.

[0004] Currently, in the production process, there is a way to effectively recycle and process the eliminated waste needles by relying on manual magnification, manual identification, selection, etc. This method wastes a lot of manpower and has low efficiency. Utility Model Content

[0024] Optionally, the limiting assembly includes a mounting plate, the mounting plate is detachably connected to the side plate and can be adjusted in height up and down.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0044] The following further describes the present application in detail with reference to the attached Figures 1 - 4 drawings.

[0045] The needle screening device provided by the embodiments of the present application aims to solve the problem of screening waste needles after the carbon fiber preform production process, so as to improve product quality and production efficiency.

[0046] Referring to Figure 1 , according to the processing technology of the needles, the needle screening device includes a frame 10 and a feeding vibrating disk 20, a preliminary screening mechanism 30, a screening manipulator 40, a positioning conveyor line 50, and a needle collection box 60 which are installed in the frame 10 and arranged in sequence along the needle processing technology.

[0047] First of all, the feeding vibrating disk 20 is used to orderly arrange and convey a large number of messy needles. A limiting plate 21 is arranged at its discharge end, and a needle discharge port 22 is formed between the limiting plate 21 and the feeding vibrating disk 20. In this embodiment, the limiting plate 21 is provided with a long strip hole 211 along the height direction. Through this long strip hole 211, the height of the limiting plate 21 in the feeding vibrating disk 20 can be adjusted. By adjusting the height of the limiting plate 21, the size of the needle discharge port 22 can be controlled, so as to adjust the needle discharge speed, so as to ensure that the needles enter the next screening link at an appropriate rate.

[0048] Next, the preliminary screening mechanism 30 is responsible for receiving the needles conveyed from the feeding vibrating disk 20 and preliminarily screening out the broken needles among them. The preliminary screening mechanism 30 includes a screening box 31 and a screening plate 32. A first vibration device (not shown in the figure) is equipped in the screening box 31, and this device can drive the screening plate 32 to vibrate to ensure that the needles are evenly distributed on the screening plate 32 and avoid overlapping. Specifically, the first vibration device can be a vibration motor.

[0049] Among them, an exposure lamp (not shown in the figure) is also installed in the screening plate 32. The screening plate 32 can be a semi-transparent plate, and the exposure lamp exposes the plate surface of the screening plate 32 to enhance the accuracy of visual recognition. In addition, a first visual recognition camera (not shown in the figure) is arranged above the screening plate 32. This camera can quickly identify the worn needles and is electrically connected to the screening manipulator 40 to ensure that once the worn needles are recognized, the screening manipulator 40 can immediately react, pick them out from the screening plate 32, and put them on the positioning conveyor line 50.

[0050] In addition, in order to facilitate the subsequent treatment of the broken needles, in this embodiment, a broken needle discharge port 311 is also provided on one side of the screening box 31 far from the feeding vibrating disk 20, and a broken needle collection box 33 is installed at its discharge end. After the worn needles are screened out, the broken needles can move to the broken needle collection box 33 under the vibration action, which is convenient for the collection and treatment of the broken needles. In other embodiments, the broken needle discharge port 311 can also not be provided, and the screening manipulator 40 is used to convey the broken needles to the broken needle collection box 33.

[0051] Subsequently, the selected qualified lancets will be transferred by the screening manipulator 40 to the positioning conveyor line 50. In this embodiment, the positioning conveyor line 50 is a belt conveyor line or a synchronous belt conveyor line. The lancets are placed horizontally on the positioning conveyor line 50 and are conveyed by the positioning conveyor line 50 to the next process.

[0052] Referring to Figure 2 , at the end of the positioning conveyor line 50, there is a lancet collection box 60 for collecting the qualified lancets screened through the above process. To meet the collection requirements of different types of lancets, at least two lancet collection boxes 60 are provided along the conveying direction of the positioning conveyor line 50, so that the lancets can be separately collected into different lancet collection boxes 60 according to their specific classifications.

[0053] To specifically classify the lancets and separately collect them into different lancet collection boxes 60, the embodiment of the present application further includes a second vision recognition camera 70 and a lancet blanking device 80. <9>

[0054] The second vision recognition camera7 is installed inside the frame and above the positioning conveyor line 50 for more detailed classification of the conveyed lancets, which is electrically connected to the lancet blanking device 8 and can control the lancet blanking device 8 to operate accurately in real time <00001<9><9><0000<9><000012<9> <00001<9><9><9><0000<9><000012<9>

[0055] Referring to Figures 2 - 4 , the lancet blanking device 80 includes side plates 81, a supporting plate 82 and a gas supply assembly. The side plates 81 are installed inside the frame 10 through mounting seats 83. The supporting plate 82 is detachably installed on the side of the side plates 81 and below the inner side of the positioning conveyor line 50. The lancets are placed on the upper surface of the supporting plate 82 and the positioning conveyor line 50 during conveyance. An air hole 821 is provided on the top surface of the supporting plate 82 on the side away from the lancet collection box 60. The air hole 821 penetrates through the side plates 81 to connect to the gas supply assembly (not shown in the figure). The gas supply assembly is electrically connected to the second vision recognition camera 70. Specifically, the gas supply assembly can be a combination of a gas source and a gas valve, and the opening and closing of the gas are controlled by the gas valve.

[0056] The second vision recognition camera 70 measures the size of the lancets, determines the size of the lancets and classifies them. Once the second vision recognition camera 70 identifies a specific type of lancet, it will control the air hole 821 to blow out air flow through the gas supply assembly, and accurately blow the lancets into the corresponding collection boxes.

[0057] To ensure the stability of the lancets during conveyance, a limiting assembly 90 is further installed on the side plates 81 above the positioning conveyor line 50 to ensure that the lancets will not shift during conveyance. It should be noted that the limiting assembly 90 is not provided directly above the air hole 821 to avoid affecting the normal blanking of the lancets.

[0058] Among them, the limit component 90 includes a mounting plate 91 that is detachably connected to the side plate 81 and has adjustable height. A limit bar 92 is installed on the bottom side of the mounting plate 91, and the limit bar 92 extends along the length direction of the positioning conveyor line 50. By adjusting the height of the mounting plate 91, the device can adapt to the feeding requirements of needles of different sizes. In addition, one end of the limit bar 92 facing the feeding direction is bent upward to form a flared shape. This design enables the needles to enter the limit area more smoothly, thereby improving the feeding efficiency.

[0059] In summary, through the automated and intelligent design, the needle screening device of the present application realizes the efficient and accurate screening and classification of needles, greatly improving the production efficiency and reducing the labor cost.

[0060] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
