Abstract
Description
Technical Field
[0001] This utility model relates to a tool, specifically a nail inspection tool. Background Technology
[0002] A nut is a type of nail with threads and a nut, primarily used for fixing and connecting various materials such as wood, metal, and stone. Through its threaded and nut design, it can form a sturdy whole with other components (such as metal plates, corner brackets, and wood), and is widely used in construction, furniture, and decoration.
[0003] In the nut and nail manufacturing process, the step of pressing the nut and nail into the sheet metal is called nailing. The number and position of nails in the product are disordered and irregular. During the operation by employees, it is inevitable that some nails will be missed. Therefore, it is necessary to add an inspection process to improve the product yield. Utility Model Content
[0004] The purpose of this utility model is to provide a nut inspection tool that can detect the presence or absence of nuts on products at a lower cost, significantly reducing the outflow of defective products and lowering the inspection cost.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a nail inspection tool, comprising a support mechanism, a positioning mechanism and a detection mechanism located on one side of the positioning mechanism, wherein the support mechanism includes a top support plate, which is horizontally arranged; the positioning mechanism includes a positioning pin and an outer support fixed to the outside of the positioning pin, wherein multiple positioning pins and outer supports are provided; the detection mechanism includes a high-current probe and a low-current probe, both of which are vertically arranged; the detection mechanism also includes a nail indicator light and a power switch, wherein multiple nail indicator lights are provided, the number of which is determined by the number of nails being inspected, with each nail corresponding to one indicator light; when the inspection tool is running, the indicator light at the corresponding position is lit to indicate the presence of a nail, and if it is not lit, it indicates the absence of a nail. This inspection tool is suitable for continuous production lines of robotic arms, and can detect missing nails and nails not placed in place while positioning products. By connecting to stamping equipment with a dedicated aviation plug, the outflow of defective products can be reduced at a lower cost, thereby achieving the purpose of cost reduction and efficiency improvement.
[0006] Preferably, the support mechanism further includes a bottom support plate and two side support plates. The two side support plates are fixed to both sides of the upper surface of the bottom support plate, and the top support plate is fixed to the upper surface of the two side support plates, so that the structure of the top support plate remains stable. The bottom support plate, side support plates, sealing plate and top support plate are all made of bakelite.
[0007] Preferably, a sealing plate is also fixed to the upper end face of the bottom support plate, and both side support plates are fixedly connected to the sealing plate; the bottom support plate, the two side support plates, the sealing plate and the top support plate form a cuboid structure, which has an opening through which electrical components are installed.
[0008] Preferably, both the locating pin and the outer support are fixed to the upper end face of the top support plate by screws.
[0009] Preferably, the positioning mechanism also includes multiple storage seats, each of which is fixed to the upper surface of the top support plate by screws.
[0010] Preferably, the high-current probe is fixed on the first pad, and the low-current probe is fixed on the second pad. Both the first pad and the second pad are fixed to the upper end face of the top support plate.
[0011] Preferably, the testing mechanism also includes a power indicator light, and the power switch, power indicator light and multiple nut nail indicator lights are all located on the top support plate.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: When there is a nut nail at the corresponding position of the product, the metal nut nail contacts the small current probe, connecting to the negative terminal represented by the product board. At this time, the nut nail indicator light circuit is connected and lights up. When there is no nut nail at the corresponding position, the small current probe passes directly through the hole pre-set for the nut nail in the product board. At this time, the small current probe circuit cannot be connected and therefore does not light up. This allows for the determination of whether there is a nut nail at the specified position. Thus, the function of detecting the presence or absence of a nut nail in the product is realized at a lower cost, avoiding missed detection, significantly reducing the outflow of defective products, and lowering the detection cost.

[0021] The working process of this utility model:
[0022] 1. Employees place products from the previous process to the testing facility 3;
[0023] 2. Each nut pin contacts its corresponding small current probe 32;
[0024] 3. After each small current probe 32 contacts the corresponding nut nail, the corresponding nut nail indicator light 35 of this group of circuits is turned on;
[0025] 4. When all the nut indicator lights are on at 35, it means that there are no missing nuts in this inspection, and the product has passed the inspection.
[0026] 5. The inspected product is manually removed, and the next product is inspected, and so on.
[0027] When determining whether a nut is present at a specified location: When the product is placed on the testing mechanism 3, the product board contacts the high-current probe 31, and the product itself acts as the negative terminal of the circuit. The lower end of the low-current probe 32 is connected to the negative terminal of the nut indicator light 35, and the positive terminal of the power supply is connected to the positive terminal of the nut indicator light 35. When there is a nut at the corresponding location, the metal nut contacts the low-current probe 32, connecting the negative terminal represented by the product board. At this time, the circuit of the nut indicator light 35 is connected, and the nut indicator light 35 lights up. When there is no nut at the corresponding location, the low-current probe 32 passes directly through the hole pre-drilled for the nut in the product board. At this time, the circuit of the low-current probe 32 cannot be connected, and the nut indicator light 35 does not light up. Manual inspection can be conducted by observing the number of lit nut indicator lights 35 to determine whether the product passes the test and to quickly locate the missing nut.
[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
