Description

Technical Field

[0001] This utility model relates to a wire harness dispensing fixture, and more particularly to a foolproof tooling for blind plugging assembly of plastic housings. Background Technology

[0002] In the production process of wire harness connectors, blind plugs are often required to be installed on specific pins of the plastic housing to achieve waterproofing, dustproofing, or to reserve holes. Traditional assembly methods mainly rely on operators manually inserting the blind plugs into the plastic housing one by one. This method has the following obvious drawbacks: 1. Low efficiency: Manually plugging in each one is slow and cannot achieve batch processing.

[0003] 2. Prone to errors: On multi-pin plastic shells, it is very easy to insert the wrong pin (insert it in the wrong position) or miss the pin.

[0004] 3. Difficulty in ensuring orientation: Blind plugs usually have directional requirements (such as the raised side needing to correspond to the raised groove side of the plastic shell), which are easily overlooked or reversed during manual operation, leading to assembly failure.

[0005] 4. Inconsistent assembly quality: Whether the blind plug is pressed in place (with a "click" sound) depends entirely on the operator's feel and sense of responsibility, resulting in poor quality stability.

[0006] 5. High quality inspection costs: Due to the aforementioned human factors, a large amount of additional manpower is required for full inspection, which unnecessarily increases production and management costs.

[0007] Therefore, there is an urgent need for a blind plug assembly tooling that can achieve fast, accurate, error-proof, and consistent assembly. Utility Model Content

[0008] To address the shortcomings of the aforementioned technologies, this utility model provides a foolproof tooling for blind plugging assembly of plastic shells.

[0009] To solve the above technical problems, the technical solution adopted by this utility model is: a foolproof tooling for assembling blind plugs in plastic shells, comprising: a storage box, the upper part of which has an opening and forms a recessed cavity for accommodating a top cover plate; multiple interface stations are arranged in an array on the bottom surface of the recessed cavity, each interface station having several pins arranged in the same order; a top cover plate is detachably connected to the open end of the storage box and completely covers the recessed cavity; the top cover plate has anti-misoperation guide holes corresponding to the pin positions, the anti-misoperation guide holes being formed in a way that guides the insertion of external blind plugs; it also includes a foolproof positioning component disposed on the edge of the top surface of the storage box, the foolproof positioning component being implemented in a way that restricts the displacement and opening and closing of the top cover plate. Further, the multiple interface stations are arranged in a grid array, each interface station having an upwardly protruding boss, the sum of the maximum height of the boss of the interface station and the maximum thickness of the top cover plate not exceeding the maximum recessed depth of the recessed cavity. Further, several pins are machined on the pin positions. Furthermore, the storage box has multiple matching slots on its side wall, and the number of the foolproof positioning components matches the number of matching slots. Furthermore, the foolproof positioning component is angle iron-shaped and includes an integral matching flange and a fastening flange. The matching flange abuts against the matching slot, and the fastening flange spans the top surface of the side wall and the top surface of the top cover of the storage box. Furthermore, the fastening flange has positioning component mounting holes that match the cover plate mounting holes on the top cover. Furthermore, the error-proof guide holes include a first error-proof guide hole and a second error-proof guide hole. The first and second error-proof guide holes are set together, and their positions correspond one-to-one with the pins in the corresponding pin positions where blind plugs need to be inserted.

[0010] A foolproof tooling for assembling blind plugs for plastic shells achieves batch positioning through structural design. It works in conjunction with a transparent cover plate with anti-misalignment guide holes for physical limiting, fundamentally eliminating the possibility of incorrect or missed insertion of blind plugs. The foolproof positioning structure ensures the cover plate is closed in only one direction, guaranteeing that all plastic shells are oriented consistently, ensuring the correct orientation of the blind plugs. The anti-misalignment guide holes also guide and correct the insertion process of the blind plugs, ensuring uniform assembly depth, significantly improving assembly efficiency and product yield, and reducing operational difficulty and inspection costs.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0016] like Figure 1-3 As shown in the figure, the foolproof tooling for assembling blind plugs in this embodiment mainly includes a storage box 1, a top cover plate 9, and a foolproof positioning component 6, as detailed below: like Figure 1-2 As shown, the storage box 1 is an open box made of ABS engineering plastic. The opening of the storage box 1 forms a recessed cavity 2 to accommodate the top cover plate 9 to be assembled. In actual processing, the top cover plate 9 is made of colorless transparent acrylic sheet to allow observation of the interior. The bottom surface of the recessed cavity 2 has multiple interface stations 3 arranged in an array. Each interface station 3 forms an upward protruding boss with several identically arranged pin positions 4. The sum of the maximum height of the boss of the interface station 3 and the maximum thickness of the top cover plate 9 is not greater than the maximum recessed depth of the recessed cavity 2, thereby ensuring that the cover plate can cover stably.

[0017] The storage box 1 has multiple matching slots 5 on its side wall for engaging with the foolproof positioning component 6; the top cover 9 is detachably connected to the open end of the storage box 1 and completely covers the recessed cavity 2; the top cover 9 has multiple error-proof guide holes, the positions of which correspond one-to-one with the specific pins in the pin positions 4 that require the insertion of blind plugs, serving as guidance and error prevention; and so on. Figure 3 As shown, the error-proof guide hole includes a first error-proof guide hole 11 and a second error-proof guide hole 12. In this embodiment, the first error-proof guide hole 11 and the second error-proof guide hole 12 are arranged in a group, respectively corresponding to the blind plug insertion requirements at different positions. It should be noted that in actual processing, not all pins in pin position 4 that need to be plugged with blind plugs are as shown in this embodiment. Therefore, this example does not limit the specific shape of the first error-proof guide hole 11 and the second error-proof guide hole 12. Those skilled in the art can process the required shape according to actual needs.

[0018] The foolproof positioning component 6 is set on the top edge of the storage box 1, and its number matches the number of the matching groove 5. The foolproof positioning component 6 is in the shape of an angle iron and includes an integral matching flange 7 and a fastening flange 8. During assembly, the matching flange 7 abuts against the matching groove 5 to achieve horizontal positioning, while the fastening flange 8 spans across the top surface of the side wall of the storage box 1 and the top surface of the top cover plate 9 to achieve vertical pressing. The fastening flange 8 is provided with a positioning component assembly hole 13, which matches the cover plate assembly hole 10 opened on the top cover plate 9, and is used to insert fasteners to lock the whole, ensuring that the top cover plate 9 does not shift during operation.

[0019] The working principle of this embodiment is as follows: First, place the top cover 9 onto the recessed wall 2 of the storage box 1 in its only correct orientation; at this point, the assembly can be confirmed to be in place through the transparent material of the top cover 9.

[0020] Next, the four foolproof positioning parts 6, which are inherently designed, are respectively inserted into the matching grooves 5 on the side wall of the storage box 1 through their matching flanges 7, and are fastened with screws through the positioning part assembly holes 13 and the cover plate assembly holes 10. During this process, the fastening flanges 8 of the foolproof positioning parts 6 simultaneously press against the side wall of the storage box 1 and the edge of the top cover plate 9, thus limiting any horizontal displacement of the top cover plate 9 and preventing it from being accidentally opened in the vertical direction. This ensures that the first and second foolproof guide holes 11 and 12 on the top cover plate 9 are always precisely aligned with the pins that need to be operated on the lower plastic shell, thus achieving foolproof closing direction.

[0021] Then, the operator takes the blind plug and inserts it vertically into the corresponding pin position 4 through the first anti-mistake guide hole 11 and the second anti-mistake guide hole 12 exposed on the top cover plate 9. The anti-mistake guide hole plays an effective guiding and straightening role in the pressing process of the blind plug, which helps the operator to apply force evenly and press each blind plug into place until a clear "click" sound is heard, indicating that the blind plug has been assembled in place.

[0022] After all blind plugs are assembled, remove the foolproof positioning piece 6, open the top cover plate 9, and then take out the assembled parts from the storage box 1.

[0023] This application discloses a foolproof tooling for assembling blind plugs for plastic shells. Through structural design, it achieves batch positioning and uses a transparent cover plate with anti-misalignment guide holes for physical limiting, fundamentally eliminating the possibility of incorrect or missed insertion of blind plugs. The foolproof positioning structure ensures that the cover plate is closed in only one direction, guaranteeing that all plastic shells are oriented in the same direction, ensuring that the blind plugs are in the correct direction. The anti-misalignment guide holes also guide and correct the blind plug insertion process, ensuring uniform assembly depth, significantly improving assembly efficiency and product yield, and reducing operational difficulty and inspection costs.

[0024] The above embodiments are not intended to limit the present invention, nor is the present invention limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present invention are also within the protection scope of the present invention.
