Description

Technical Field

[0001] This utility model relates to the field of testing tooling technology, and more specifically, to a tooling for quickly positioning single-hole products for easy inspection. Background Technology

[0002] Rubber single-hole products such as Figure 1 As shown, products can be categorized into cable sheaths, sealing plugs, and insulating sleeves, typically featuring channels for threading electrical wires, signal lines, or other cables. However, during the injection molding process of single-hole products, these channels often become clogged due to sprue residue or mold burrs. Furthermore, mold needle breakage during long-term use can leave broken parts within the product channels, also posing a risk of blockage. Traditional inspection methods rely on manual visual inspection or the use of simple tools to check each piece individually for blockage. This is not only inefficient but also prone to missed detections due to visual fatigue, especially for small-diameter or tiny rubber parts. Therefore, a highly efficient and reliable inspection tool is urgently needed to solve the problem of detecting blockages in single-hole rubber products. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned defects in the prior art and provide a simple, easy-to-operate, and low-cost testing fixture that can achieve rapid and accurate positioning and efficient inspection of multiple single-hole products.

[0004] To achieve the above objectives, this utility model provides a tooling for quick positioning and inspection of single-hole products, comprising a first plate, a second plate, a light-transmitting plate, and an optical inspection mold base. The first plate, the second plate, and the light-transmitting plate are stacked sequentially from top to bottom. The first plate has a plurality of first through holes distributed in an array, and the second plate has a plurality of second through holes distributed in an array and coaxial with each first through hole. The diameter of the first through holes is larger than the diameter of the second through holes. The same corner of the first plate, the second plate, and the light-transmitting plate is set as a first chamfer. The top side of the optical inspection mold base is recessed with a positioning groove for placing the first plate, the second plate, and the light-transmitting plate together. The inner apex corner of the positioning groove is set as a second chamfer to cooperate with the first chamfer for positioning. When the first plate, the second plate, and the light-transmitting plate are stacked in alignment, the first chamfer forms a continuous guide slope, which can form a plug-in positioning fit with the second chamfer of the optical inspection mold base.

[0005] Preferably, the optical inspection mold base includes a base body and a light source, the positioning groove is formed on the top side of the base body, and the light source is fixedly installed on the inner end face of the positioning groove of the base body facing upward.

[0006] Preferably, the first plate, the second plate, and the light-transmitting plate are all made of transparent acrylic.

[0007] Preferably, the first plate, the second plate, and the light-transmitting plate are of the same size and thickness.

[0008] Preferably, both the first chamfer and the second chamfer are configured as either beveled chamfers or rounded chamfers.

[0009] Preferably, the chamfer angle is set to 45° or 30°.

[0010] Preferably, the seat body is configured as a cuboid, and the outer edge of the opening of the positioning groove forms a groove transition surface. The groove transition surface has inverted L-shaped limiting sidewalls formed on the two outer edges corresponding to the second chamfer.

[0011] Preferably, the first plate, the second plate, and the light-transmitting plate are all square in shape, and the right-angled edges of the first plate, the second plate, and the light-transmitting plate extend beyond the other two sides of the transition surface of the positioning groove.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Please refer to Figure 1 The present invention provides a tooling for quick positioning of single-hole products for easy inspection, including a first plate 1, a second plate 2, a light-transmitting plate 3 and an optical inspection mold base 4. The components of this embodiment will be described in detail below with reference to the accompanying drawings.

[0025] like Figures 1 to 3As shown, the first plate 1, the second plate 2, and the light-transmitting plate 3 can be stacked sequentially from top to bottom. The first plate 1 is provided with a number of first through holes 11 distributed in an array. The second plate 2 is provided with a number of second through holes 21 distributed in an array and on the same axis as each first through hole 11. The diameter of the first through hole 11 is larger than the diameter of the second through hole 21. The same side corner of the first plate 1, the second plate 2, and the light-transmitting plate 3 is set as a first chamfer 101.

[0026] In this embodiment, the diameters of the first through hole 11 and the second through hole 12 are both larger than the diameter of the single-wire hole product 5. The diameter of the first through hole 11 is larger than the diameter of the second through hole 12, forming a stepped aperture structure. When the single-wire hole product 5 is scattered on the first plate 1, the single-wire hole product 5 will fall vertically into the second through hole 12 due to the difference in aperture. The second through hole 12 can ensure that the product is stable in position during the inspection process. The light-transmitting plate 3 can also support the second plate 2, the first plate 1 and the product above, ensuring that the inspection plane is flat and realizing the positioning of the product.

[0027] Among them, the single-wire hole product 5 can be any kind of single-wire hole product commonly found on the market. In fact, it does not involve structural improvements to the single-wire hole product 5, so it will not be described in detail. During production, the diameter of the first through hole 11 and the second through hole 12 can be adaptively adjusted according to the diameter of the corresponding single-wire hole product 5.

[0028] Specifically, the top side of the optical inspection mold base 4 is recessed with a positioning groove 40 for placing the first plate 1, the second plate 2 and the light-transmitting plate 3 together. The inner top corner of the positioning groove 40 is set as a second chamfer 401 that cooperates with the first chamfer 101 for positioning.

[0029] In this embodiment, the first plate 1, the second plate 2, and the light-transmitting plate 3 are of the same size and thickness.

[0030] Furthermore, the materials of the first panel 1, the second panel 2, and the light-transmitting panel 3 can all be made of transparent acrylic to facilitate light transmission.

[0031] like Figure 5 and Figure 6 As shown, in specific implementation, when the first plate 1, the second plate 2 and the light-transmitting plate 3 are stacked in alignment, the first chamfer 101 forms a continuous guide slope, which can form a plug-in positioning fit with the second chamfer 401 of the optical inspection mold base 4.

[0032] The first chamfer 101 and the second chamfer 401 are both set as either beveled chamfers or rounded chamfers.

[0033] Specifically, the chamfer angle is set to 45° or 30°. In this embodiment, the first chamfer 101 and the second chamfer 401 preferably adopt a 45° chamfer angle.

[0034] like Figure 7 As shown, the optical inspection mold base 4 includes a base 41 and a light source 42. A positioning groove 40 is formed on the top side of the base 41, and the light source 42 is fixedly installed on the inner end face of the positioning groove 40 of the base 41 facing upward.

[0035] The light source 42 can be set as an LED bulb, which can provide light for detection. The light can pass through the light-transmitting plate 3 and the channel of the single-line hole product 5, so as to determine whether the channel is blocked by optical detection. It is inexpensive and easy to obtain.

[0036] In this embodiment, the structure of the base 41 is set as a cuboid, and the outer edge of the opening of the positioning groove 40 forms a groove transition surface 411. The groove transition surface 411 corresponds to the two outer edges of the second chamfer 401 and respectively forms an inverted L-shaped limiting sidewall 412. The groove transition surface 411 facilitates the placement of each plate, and the limiting sidewall 412 can prevent the plate from shifting when it is placed.

[0037] Furthermore, the first plate 1, the second plate 2, and the light-transmitting plate 3 are all square in shape, and the right-angled edges of the first plate 1, the second plate 2, and the light-transmitting plate 3 extend to the other two sides of the groove transition surface 411 of the positioning groove 40, which facilitates manual handling.

[0038] The working principle of this embodiment is as follows:

[0039] like Figure 8 As shown, the first plate, the second plate, and the light-transmitting plate are first stacked in sequence, aligned and aligned. At this time, the first chamfer of the same side corner of the first plate, the second plate, and the light-transmitting plate forms a continuous guide slope. Then, multiple single-hole products are scattered on the first plate. Since the diameter of the first through hole is larger than that of the second through hole, the single-hole products will fall vertically into the second through hole. The precise positioning of the products is achieved through the cooperation of the first plate and the second plate. Then, the stacked components are placed into the positioning groove of the optical inspection mold base. The tooling is inserted and positioned through the plug-in cooperation of the guide slope and the second chamfer of the positioning groove, as well as the limiting side wall and other structures. Finally, the light source in the mold base is turned on, and the light shines from below the light-transmitting plate. Then, the image acquisition unit above it takes pictures for inspection. If the product channel is not blocked, the light can pass through the channel. If it is blocked, the light will pass through abnormally. The blockage of the single-hole product channel can be judged by whether the light passes through smoothly.

[0040] In summary, this utility model enables rapid synchronous positioning of multiple single-line hole products through the array-type through-hole design on the first and second plates. The positioning structure of the first chamfer of each plate and the second chamfer of the optical inspection mold ensures rapid insertion and alignment with the optical inspection mold. The operation is simple and convenient. Furthermore, optical inspection can quickly determine whether the channel of the single-line hole product is blocked, significantly reducing the missed detection rate, resulting in high detection efficiency and low cost.

[0041] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
