Description

Technical Field

[0001] This utility model relates to the field of detection technology, specifically to a fault-proof detection device. Background Technology

[0002] In daily production, the automotive industry involves a wide variety of parts, such as wire threaded sleeves and nuts. Each part plays a crucial role in the final product. If a part is missing, it can affect the overall performance of the product and may even lead to its scrapping. Currently, the installation status of parts within a product mainly relies on manual inspection. However, manual inspection is not only inefficient but also prone to omissions.

[0003] To address the aforementioned issues, a CCD inspection technology has emerged in the prior art. CCD inspection equipment identifies parts to be inspected through visual inspection, not only identifying the presence or absence of parts but also detecting surface defects or flaws. For example, Chinese utility model patent ZL201520844710.2 (publication number CN205139028U), entitled "An Automatic Inspection Device for Brake Pad Backplate Based on Machine Vision," discloses such a device. This device includes an industrial CCD camera, which can accurately detect appearance defects, dimensional errors, and unclear stamped characters on brake pad backplates, effectively ensuring brake pad quality. However, industrial CCD cameras are susceptible to influences from light sources and environmental factors, leading to misjudgments during use. If missing parts within the product are not identified, serious consequences can result.

[0004] Therefore, further improvements are needed to the structure of the error-proofing detection mechanism. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a fault-proofing detection device that can accurately detect the installation status of parts in a product, in light of the above-mentioned existing technology.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problem is as follows: the error-proofing detection device, characterized in that it includes:

[0007] A workbench, on top of which a product is placed, and inside the product are parts to be tested;

[0008] A fixed base is provided on the worktable;

[0009] An installation component is disposed on the fixed base, and the installation component has a first installation space.

[0010] The trigger is at least partially disposed within the first mounting space. When the product is driven downward by an external force, the part to be tested can be fitted onto the mounting and the trigger is applied downward, thereby driving the mounting to move downward synchronously.

[0011] A sensor, located below the mounting component, senses the movement of the mounting component, converts it into an electrical signal, and outputs a detection result to determine the installation status of the part to be detected.

[0012] To avoid external interference, a connecting member is preferably included. The connecting member has an "L"-shaped cross-section and includes a first vertical portion for inserting the mounting component and a first horizontal portion for inserting the sensor. A first fixing member is provided at the connection point between the sensor and the first horizontal portion. The connecting member has an internal cavity, which provides a closed environment for the sensor to receive movement signals from the mounting component. Both the sensor and the mounting component are inserted into the connecting member. The sensor senses the movement of the mounting component, converts it into an electrical signal, and then outputs a detection result to determine the installation status of the part to be detected.

[0013] To facilitate the repositioning of the mounting component, a vertically extending second mounting space is provided at the bottom of the mounting component. An elastic element is disposed within this second mounting space, and a limiting portion is provided on the inner wall of the connecting component. This limiting portion is located below the elastic element and allows the elastic element to abut against it, thereby causing the mounting component to reposition upwards. Specifically, when the part to be tested is installed, the trigger and the mounting component are compressed and move downwards. The elastic element in the second mounting space abuts against the limiting portion. After the sensor completes its detection, the product moves upwards, and the mounting component and trigger are repositioned upwards by the rebound action of the elastic element.

[0014] Meanwhile, to facilitate the resetting of the mounting component, another approach is to include an elastic element inside the connector. This elastic element is positioned directly below the mounting component and allows the mounting component to abut against it, thus resetting it upwards. Specifically, when the part to be tested is installed, the trigger and the mounting component are compressed and move downwards, with the mounting component abutting against the elastic element. After the sensor completes its detection, the product moves upwards, and the mounting and trigger components reset upwards under the rebound of the elastic element.

[0015] To facilitate the movement of the part to be inspected to a designated position, preferably, the mounting component includes a first segment and a second segment connected to each other. The cross-sectional area of ​​the first segment is smaller than that of the second segment, and a limiting step is formed between the first and second segments. This limiting step can limit the movement of the part to be inspected. Specifically, when the entire product moves downward, the part to be inspected moves downward synchronously. The prerequisite for the mounting component to move downward is that the part to be inspected is precisely fitted onto the mounting component. At this point, the inner wall of the part to be inspected needs to contact the triggering element. This application, by setting the limiting step, ensures that the bottom wall of the part to be inspected abuts against the limiting step, at which point the part to be inspected moves precisely to the designated position, and the product stops moving.

[0016] For ease of device fixation, preferably, a base is provided on the worktable, and a fixing seat is mounted on the base. The fixing seat has an "L"-shaped cross-section, including a second vertical portion extending upward from the base in a vertical direction, and a second horizontal portion extending laterally from the top of the second vertical portion. The base is mounted on the worktable by a fixing member, and the second vertical portion of the fixing seat is fixed to the base by the fixing member. The second horizontal portion of the fixing seat is at a predetermined distance from the worktable, thus creating space below the second horizontal portion for component installation. The second horizontal portion can be used to fix and install components such as converters and mounting parts.

[0017] Furthermore, the second transverse portion is provided with a mounting hole, which allows the end of the connector to pass through. The connector is provided with second fixing members on both sides corresponding to the mounting hole. The mounting member is inserted into the end of the connector, the end of the connector being cylindrical. The mounting hole on the second transverse portion allows the end of the connector to pass through, and the second fixing members on both sides of the mounting hole fix the connector to the second transverse portion.

[0018] Compared with the prior art, the advantages of this utility model are: by setting the trigger and the mounting part, the trigger and the mounting part can be driven to move down synchronously when the product with the part to be tested moves down. After the sensor receives the signal of the mounting part approaching, it is converted into an electrical signal output. The mechanical motion signal acquisition is not easily affected by external factors, and the detection accuracy is high. Attached Figure Description

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] Example 1:

[0028] like Figures 1 to 5 The diagram shows the preferred embodiment of this utility model. This error-proofing detection device includes a workbench 1, a product positioned above the workbench 1, and a part to be tested disposed within the product. A fixed base 2 is mounted on the workbench 1, and a mounting component 3 is mounted on the fixed base 2. The mounting component 3 has a first horizontal mounting space 31, and an actuating element 4 is disposed within the first mounting space 31, with a portion of the actuating element 4 exposed outside the first mounting space 31. When the product is driven downward by external force, the part to be tested can be fitted onto the mounting component 3, and downward pressure is applied to the actuating element 4, thereby causing the mounting component 3 to move downward synchronously. A sensor 5 is disposed below the mounting component 3. The sensor 5 senses the movement of the mounting component 3, converts it into an electrical signal, and outputs the detection result. In this embodiment, two sets of devices capable of simultaneously detecting the part to be tested are symmetrically arranged on the workbench 1, thereby improving detection efficiency.

[0029] Currently, for the installation of parts inside products, existing technologies mostly use CCD inspection technology to replace manual inspection. While CCD improves inspection efficiency compared to manual inspection, it also has drawbacks: CCD cameras are susceptible to environmental and light source factors, leading to misjudgments during the inspection process. Therefore, this application replaces the image signal in CCD inspection technology by converting the signal of mechanical extension and retraction into an electrical signal, referencing... Figure 3 and Figure 4In this embodiment, the cross-section of the connector 6 is "L" shaped. The connector 6 includes a first vertical part 61 for the installation part 3 to be inserted and a first horizontal part 62 for the sensor 5 to be inserted. A first fixing part 7 is provided at the connection between the sensor 5 and the first horizontal part 62. The connector 6 has a cavity inside to create an environment that avoids external interference. The sensor 5 senses the movement of the installation part 3 and converts it into an electrical signal, and then outputs the detection result to determine the installation status of the part to be detected.

[0030] During the testing process, the actuating element 4 and the mounting element 3 move downward under the actuation force of the product. The sensor 5 senses the movement of the mounting element 3 and converts it into an electrical signal, thereby outputting the test result to determine the installation status of the part to be tested. After the test is completed, the mounting element 3 and the actuating element 4 need to be returned to their original positions for the next round of testing. For this purpose, this embodiment provides a vertically extending second mounting space 35 at the bottom of the mounting element 3. The second mounting space 35 is distributed on both sides, and each second mounting space 35 is provided with an elastic element 8. The elastic element 8 can be in various forms, such as springs and sheet springs. In this embodiment, a spring that is easy to install is preferred. When the part to be tested is installed, the actuating element 4 and the mounting element 3 will be compressed and move downward synchronously. The elastic element 8 in the second mounting space 35 will abut against the limiting part 63. After the sensor 5 completes the test, the product moves upward, and the mounting element 3 and the actuating element 4 are reset upward under the rebound action of the elastic element 8.

[0031] Meanwhile, the premise for the installation component 3 to move is that the part to be tested moves to the designated position. At this time, the inner wall of the part to be tested needs to come into contact with the trigger 4. In this embodiment, the installation component 3 is set in two sections, and the first section 32 is set with a smaller diameter than the second section 33, thereby forming a limiting step 34 to limit the part to be installed. By setting the limiting step 34, the bottom wall of the part to be tested can be made to abut against the limiting step 34. At this time, the part to be tested just moves to the designated position and the product stops moving.

[0032] refer to Figure 3 and Figure 4During the testing process, in order not to affect signal acquisition, all components need to maintain a certain stability. For this purpose, in this embodiment, a base 9 is provided on the workbench 1, and a fixing seat 2 is provided on the base 9. The base 9 is specially designed in an "L" shape. The purpose is that the second vertical part 22 of the fixing seat 2 is fixed to the base 9 by a fixing member, and the second horizontal part 21 of the fixing seat 2 forms a certain preset distance from the workbench 1. Therefore, a space for component installation is formed below the second horizontal part 21. A mounting hole 211 is provided on the second horizontal part 21. The mounting hole 211 allows the end of the connector 6 to pass through. The second fixing member 10 is provided on both sides of the mounting hole 211 so that the connector 6 can be fixed on the second horizontal part 21, thereby maintaining stability.

[0033] The working process of the error-proofing detection mechanism in this embodiment is as follows: The drive mechanism moves the product downward to the designated position. The trigger 4 is compressed, which in turn moves the mounting part 3 downward synchronously. At this time, the mounting part 3 gradually extends into the interior of the connector 6. The elastic element 8 in the second mounting space 35 will abut against the limiting part 63. At this time, the sensor 5 will receive the signal that the mounting part 3 is close and convert the signal into an electrical signal, and finally output the detection result that the part to be detected has been installed. After the detection is completed, the product moves upward. Under the action of the elastic element 8, the mounting part 3 drives the trigger 4 to reset upward synchronously. When the trigger 4 and the mounting part 3 remain stationary, the sensor 5 cannot receive the signal. At this time, the detection result that the part to be detected is missing is output.

[0034] Example 2:

[0035] The error-proofing detection device in this embodiment has the same structure as that in Embodiment 1, except that the elastic element 8 is positioned differently. (Refer to...) Figure 6 In this embodiment, the elastic element 8 is set at the bottom of the cavity of the connector 6. When the part to be tested is installed, the trigger 4 and the mounting part 3 will be pressed and move downward. The mounting part 3 will abut against the elastic element 8. When the sensor 5 finishes detection, the product moves upward, and the mounting part 3 and the trigger 4 are reset upward under the rebound of the elastic element 8.
