[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this application, not all embodiments.

[0029] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0030] Example 1:

[0031] Please see the appendix Figure 1-2 This application proposes a screw-driving detection device including a support mechanism 1 and a detection mechanism 2. The support mechanism 1 includes a placement member 12 connected to the housing 11, and the placement member 12 is provided with a placement hole 121 for fixing the part 3. The detection mechanism 2 includes an upper and lower corresponding linkage component 21 and a sensing component 22. The linkage component 21 is movably inserted through the housing 11 and is correspondingly set with the screw. The sensing component 22 is triggered to output a positioning signal through displacement feedback.

[0032] The housing 11 refers to the basic frame structure supporting the detection mechanism 2. Specifically, it can be assembled and welded from aluminum alloy profiles. Its internal cavity provides installation space for the sensing component 22, and its upper surface supports the placement component 12 to form a detection station. The placement hole 121 specifies the structure for positioning the part 3 to be detected. Specifically, it can be machined into a stepped hole matching the outer contour of the part 3. The inner wall boss restricts the axial displacement of the part 3, ensuring a precise correspondence between the screw installation position and the linkage component 21. The linkage component 21 refers to the transmission element that transmits mechanical displacement. Specifically, it can be a spring-returning plunger structure. When the screw is screwed into place, it is compressed, generating axial displacement and driving the end metal rod into the sensing area. The sensing component 22 refers to the signal generator that detects displacement changes. Specifically, it can be a Hall sensor combined with a magnet structure. When the linkage component 21 enters the sensing range, it outputs a pulse signal.

[0033] Specifically, when the screw is not fully installed, the linkage component 21 can maintain its initial position under the action of the elastic element, and the sensing component 22 is in a non-triggered state. During the screw insertion process, the nut contacts the pressure-bearing end face of the linkage component 21 and applies axial pressure, pushing the linkage component 21 to move. When the screw is fully in place, the trigger end of the linkage component 21 enters the effective detection area of ​​the sensing component 22, at which point the sensor outputs a high-level signal to the control system. If the screw does not reach the set depth, the displacement of the linkage component 21 is insufficient and the signal cannot be triggered, and the system determines that the installation is abnormal. This detection process is completed synchronously with the screw installation action, without the need for additional detection procedures.

[0034] The screw-driving detection device in this embodiment converts installation quality into a quantifiable electrical signal through mechanical displacement and sensor interaction. Conventional detection fixtures only provide part positioning functionality; this fixture integrates a real-time detection module on top of positioning, forming a closed-loop quality control system. Ordinary contact sensors require a separate triggering mechanism; this solution directly links the linkage component 21 to the screw installation action, achieving zero additional setup for the detection triggering mechanism.

[0035] Through the above technical solution, this application effectively eliminates the subjective error of manual visual inspection, increasing the inspection accuracy to over 99.6%. The inspection process is fully automated, with a single inspection cycle shortened to 0.3 seconds, perfectly matching the production line rhythm, effectively improving inspection efficiency and reducing labor costs. Through a physical displacement trigger signal mechanism, positional deviations as low as 0.1mm can be accurately identified, avoiding the omission of minor installation defects by traditional methods and improving inspection accuracy. The real-time signal feedback function enables online interception of abnormal parts, preventing defective products from flowing into the next process and causing greater losses.

[0036] Example 2:

[0037] The difference between this embodiment and Embodiment 1 is that, please refer to... Figure 3In this embodiment, the housing 11 is provided with an insertion hole 111. The linkage component 21 includes a needle seat 211, a sensing needle 212, and an elastic member 213. The needle seat 211 passes through the insertion hole 111. The elastic member 213 is sleeved and connected to the needle seat 211, and the elastic member 213 abuts against the edge of the insertion hole 111. The sensing needle 212 is fixedly connected to the upper end of the needle seat 211.

[0038] The insertion hole 111 refers to the through hole structure opened on the housing 11. Specifically, it can be realized by machining to form a cylindrical through hole, which is used to accommodate the needle seat 211 and limit its range of motion.

[0039] Among them, the needle holder 211 refers to a rod-shaped component with axial movement function, which can be realized by a combination structure of a metal rod and a limiting block 215, used to support the sensing needle 212 and transmit mechanical displacement.

[0040] Among them, the elastic element 213 refers to a component with axial elastic deformation capability, which can be implemented by a helical spring or an elastic rubber sleeve, and is used to provide reverse restoring force after being deformed by compression.

[0041] Among them, the sensing needle 212 refers to a slender component with rigid conductive properties. Specifically, it can be implemented by using a stainless steel needle body and a threaded connection structure, which is used to directly contact the screw and provide feedback on position information.

[0042] Specifically, when the screw is installed onto the surface of part 3, the end of the screw presses downward against the sensing needle 212, forcing the needle seat 211 to move axially along the insertion hole 111 and compressing the elastic element 213. At this time, the elastic element 213 forms a support point at the edge of the insertion hole 111, and the reverse force generated by the pressure on it continues to act on the sensing needle 212 through the needle seat 211. After the screw is installed in place, the external pressure disappears, and the elastic element 213 pushes the needle seat 211 to drive the sensing needle 212 back to its initial position. The gap between the needle seat 211 and the insertion hole 111 allows axial movement while limiting radial offset, ensuring that the sensing needle 212 always moves in the vertical direction. The contact relationship between the elastic element 213 and the edge of the insertion hole 111 forms a mechanical limit, preventing the needle seat 211 from detaching from the housing 11 or causing structural interference due to excessive downward movement.

[0043] This solution achieves automatic reset of the linkage component 21 without the need for external power by abutting the elastic element 213 with the edge of the socket 111. At the same time, the structure of the socket 111 restricts the radial movement of the needle seat 211, ensuring the repeatability accuracy of the position detection.

[0044] The above technical solution ensures that the linkage component 21 automatically returns to its initial position after each detection, eliminating signal misjudgment caused by component misalignment and effectively improving the accuracy of screw installation position detection. The continuous pressure of the elastic element 213 overcomes the frictional resistance during the movement of the linkage component 21, avoiding signal delay or loss due to minor jamming. The clearance fit structure between the socket 111 and the pin seat 211 further reduces component wear and extends the service life of the equipment.

[0045] In some embodiments, see Figure 4 The placement hole 121 is provided with a guide block 122 corresponding to the sensing needle 212. The guide block 122 is provided with a guide hole 123, and the sensing needle 212 passes through the guide hole 123.

[0046] The guide block 122 is a limiting structure fixed at the corresponding position of the placement hole 121. It can be machined from a metal block and fixed to the side wall of the placement hole 121 via threaded connection or welding, used to limit the movement trajectory of the sensing needle 212. The guide hole 123 is a cylindrical channel penetrating the guide block 122. It can be formed using precision drilling, with its inner diameter matching the outer diameter of the sensing needle 212, allowing the sensing needle 212 to slide freely axially but restricting radial offset. The sensing needle 212 is a metal detection component with a cylindrical rod shape, specifically made of stainless steel by turning. It is connected to the elastic element 213 via the needle seat 211 to form a resettable displacement transmission structure.

[0047] Specifically, the guide block 122 and the placement hole 121 form a spatial fit, with the axis of its guide hole 123 perpendicularly aligned with the screw installation path. When the screw is installed in place, the screw head presses down on the sensing needle 212, causing it to move axially along the guide hole 123 to trigger the sensing component 22. The gap between the inner wall of the guide hole 123 and the surface of the sensing needle 212 is controlled within the range of 0.05 mm to 0.1 mm, ensuring that the axial movement resistance does not exceed the restoring force of the elastic element 213 and completely eliminating the possibility of lateral offset. Under the constraint of the guide hole 123, the sensing needle 212 can only move in a straight line, avoiding distortion of the detection signal caused by lateral forces during the assembly of part 3.

[0048] This application uses the mechanical limiting effect of the guide block 122 and the guide hole 123 to strictly constrain the movement trajectory of the sensing needle 212, ensuring that the displacement signal received by the sensing component 22 maintains a fixed correspondence with the actual installation position of the screw during each test, thereby improving the stability of the test.

[0049] Through the above technical solution, this application effectively reduces the misjudgment rate caused by the offset of the detection component, and avoids downtime losses caused by detection errors in the production line. The physical limiting effect of the guide hole 123 on the sensing needle 212 can compensate for the positional tolerance during the assembly process of part 3, ensure the consistency of detection of different batches of workpieces, and extend the service life of the detection mechanism 2.

[0050] In some embodiments, see Figure 4 The inner wall of the placement hole 121 has a protruding step 124.

[0051] The step 124 refers to an annular protrusion structure formed circumferentially or locally along the inner wall of the placement hole 121. Specifically, it can be formed on the hole wall by metal cutting or injection molding. The radial dimension of this protrusion structure is larger than the original inner diameter of the hole wall, forming an axial limiting surface. When part 3 is placed into the placement hole 121, its outer edge or bottom surface contacts the protruding end face of the step 124, preventing part 3 from moving further down, thereby limiting the axial installation depth of part 3.

[0052] Specifically, the step 124 structure of the placement hole 121 forms a rigid limit through mechanical contact. When the operator places the part 3 into the hole, the part 3 moves downward under the influence of gravity until its outer surface contacts the raised end face of the step 124. At this point, the mounting plane of the part 3 forms surface contact with the step 124. Since the end face of the step 124 is perpendicular to the axis of the placement hole 121, the part 3 remains horizontal under the support of the step 124, and its axial installation position is strictly limited within a set height range. This structure achieves the positioning of the part 3 by changing the geometry of the hole wall, without the need for additional positioning fixtures or adjustment mechanisms. The rigid contact eliminates the positional uncertainty of the part 3 during placement, fundamentally solving the detection error problem caused by axial positioning deviation.

[0053] Through the above settings, this application can precisely control the installation height of part 3 within the placement hole 121, ensuring that the detection reference surface of each part 3 maintains a fixed relative position with the sensing area of ​​the detection mechanism 2. This mechanical hard-limiting method can effectively eliminate manual placement errors and improve the consistency and reliability of screw installation position detection.

[0054] In some embodiments, see Figure 5 The sensing component 22 includes a sensor 221 and a base 222. The sensor 221 is connected to the base 222, and the base 222 is connected to the housing 11.

[0055] Among them, sensor 221 refers to an electronic component used to detect whether the linkage component 21 has entered the sensing area. Specifically, it can be implemented by photoelectric sensor or magnetic induction sensor, and the position status of linkage component 21 is determined by receiving or blocking signals.

[0056] The base 222 refers to the rigid support structure that supports the sensor 221. It can be made of aluminum alloy or engineering plastic and is fixedly connected to the housing 11 by bolts or clips.

[0057] The connection refers to the mechanical fixing method between the sensor 221 and the base 222, which can be achieved by fitting or screw fastening, in order to limit the relative displacement between the two.

[0058] The connection of the housing 11 refers to the assembly method of the base 222 and the main frame of the fixture. Specifically, it can be achieved by the cooperation of the positioning pin and the mounting hole to ensure the coordinate accuracy of the sensing component 22 in three-dimensional space.

[0059] Specifically, the sensor 221 and the base 222 form a modular assembly, and the two are rigidly connected to form an independent detection unit, maintaining a constant relative position in a vibration environment. The fixed assembly of the base 222 and the housing 11 makes the sensing component 22 as a whole form a mechanical reference with the fixture, and the movement trajectory of the linkage component 21 is restricted within the detection range of the sensor 221. When the linkage component 21 is displaced by the screw installation pressure, the sensor 221 triggers a signal by detecting whether it enters the sensing slot 223. The rigid connection between the base 222 and the housing 11 eliminates the detection reference offset caused by assembly gaps.

[0060] This solution achieves secondary positioning of the sensing component 22 through the independent base 222 structure. The connection interface between the base 222 and the housing 11 can be set with a positioning reference surface, such as using planar contact fit, so that the spatial position error of the sensor 221 relative to the linkage component 21 is controlled within 0.05 mm, while the error of single-stage assembly in the prior art usually exceeds 0.2 mm.

[0061] Through the above technical solutions, this application achieves multi-point rigid fixation between the sensing component 22 and the housing 11, avoiding signal fluctuations caused by mechanical vibration during the detection process; the seat 222 structure provides an independent installation reference for the sensor 221, enabling the displacement detection of the linkage component 21 to have a repeatable reference system; the modular design allows the sensor 221 to be disassembled and calibrated separately without adjusting the overall structure of the housing 11.

[0062] In some embodiments, the sensor 221 is provided with a sensing groove 223 corresponding to the linkage component 21.

[0063] The sensing groove 223 refers to a recessed structure formed on the surface of the sensor 221 to accommodate the end of the linkage component 21. Specifically, it can be implemented as a rectangular or arc-shaped groove, with the groove depth matching the travel distance of the linkage component 21. This structure physically limits the movement path of the linkage component 21, ensuring that their positions correspond in the vertical direction.

[0064] Specifically, when the screw is in place, the linkage component 21 moves downward under mechanical action. The wall of the sensing groove 223 guides the movement trajectory of the linkage component 21, ensuring its end accurately falls into the predetermined position within the groove. At this time, the sensor 221 detects the linkage component 21 entering the sensing groove 223 via electromagnetic or photoelectric signals, determining that the screw installation meets the standard. If the screw is not fully in place, the linkage component 21 cannot reach the depth threshold of the sensing groove 223, and the signal remains in an untriggered state. This spatial matching mechanism eliminates detection errors caused by component misalignment, achieving precise positioning through the shape matching of the groove and the component.

[0065] The sensing groove 223 structure of this application forms a three-dimensional positioning space, constraining the detection area from a two-dimensional plane to a linear path, effectively reducing the probability of misjudgment caused by lateral offset. The mechanical limiting effect provided by the side wall of the groove provides a physical reference for the detection process.

[0066] The above technical solution enables accurate determination of whether the screw has reached the required installation depth. The geometric features of the sensing groove 223 limit the effective triggering range of the linkage component 21 within a predetermined area, avoiding erroneous signals caused by slight displacement or vibration of the component. The groove structure also serves a guiding function, ensuring that the relative position of the linkage component 21 and the sensor 221 remains constant during each detection process, thereby improving the repeatability and consistency of signal feedback.

[0067] In some embodiments, the base 222 is provided with a limiting groove 224 corresponding to the sensor 221, and the sensor 221 is embedded in the limiting groove 224.

[0068] The limiting groove 224 refers to the groove structure formed by machining the surface of the base 222. It can be achieved by milling or mold forming processes, and is used to provide a positioning reference and constraint boundary for the sensor 221. Embedding means that the main body of the sensor 221 is completely placed inside the limiting groove 224. It can be achieved by interference fit or snap locking, and the side wall of the groove forms a three-dimensional rigid constraint on the sensor 221.

[0069] Specifically, during assembly, the sensor 221 is pressed into the limiting groove 224 of the base 222, and the side wall of the groove contacts the outer surface of the sensor 221 to form a mechanical limit. When the linkage component 21 moves the sensing needle 212, there is no relative displacement between the sensor 221 and the base 222, and the positional accuracy of its sensing area is directly guaranteed by the machining accuracy of the limiting groove 224. Under equipment vibration or external force interference, the side wall of the limiting groove 224 continuously applies a constraint force to the sensor 221, preventing it from axially shifting or rotating circumferentially, thereby ensuring that the movement trajectory of the sensing area and the linkage component 21 always maintains spatial consistency, eliminating the adjustment process during installation, and at the same time, the groove structure forms a continuous and stable physical limit for the sensor 221.

[0070] Through the above technical solution, this application solves the problem of detection signal deviation caused by unstable installation of the sensing component 22, ensures that the relative position between the sensor 221 and the linkage component 21 remains constant during equipment operation, avoids signal misjudgment caused by small displacement, and simplifies the assembly process and reduces the dependence on manual adjustment.

[0071] In some embodiments, see Figure 5 The needle holder 211 includes a movable rod 214 and a limiting block 215. An elastic element 213 is sleeved on the movable rod 214 and connected to the limiting block 215. The diameter of the insertion hole 111 is larger than the diameter of the movable rod 214 and smaller than the size of the limiting block 215.

[0072] Among them, the movable rod 214 refers to a rigid component with a cylindrical structure, which can be made of stainless steel and achieves clearance fit by designing that the diameter is smaller than that of the insertion hole 111; the limiting block 215 refers to a protruding structure connected to the end of the movable rod 214, which can be connected to the movable rod 214 by welding or thread fixing, and forms a physical limit by designing that the size is larger than that of the insertion hole 111; the elastic element 213 refers to a compression spring that provides restoring force, which can be made of spring steel and constrains the deformation direction by being sleeved on the movable rod 214.

[0073] Specifically, when the movable rod 214 moves vertically within the socket 111, the elastic element 213 is compressed, generating a reaction force. Its deformation is confined to the axis of the movable rod 214, preventing radial displacement. When the screw is installed in place, pushing the pin seat 211 downwards, the limiting block 215 contacts the edge of the socket 111, forming a rigid barrier and preventing the movable rod 214 from moving further. At this point, the elastic element 213 is in its maximum compressed state. After the screw is removed, the elastic element 213 pushes the limiting block 215, causing the movable rod 214 to precisely return to its initial position. The clearance fit between the diameter of the socket 111 and the movable rod 214 ensures frictionless movement, while the size limitation of the limiting block 215 ensures that the movable rod 214 will not disengage from the socket 111.

[0074] This solution utilizes a combination structure of a split movable rod 214 and a limiting block 215 to transfer the force application point of the elastic element 213 to the limiting block 215. The guiding effect of the movable rod 214 forces the spring to maintain axial deformation. Reliable mechanical limiting is achieved through a simple matching of the dimensions of the limiting block 215 and the insertion hole 111, effectively eliminating the reset error caused by the offset of the elastic element 213. This ensures that the needle holder 211 accurately returns to its initial position after each test. Simultaneously, the physical interference between the limiting block 215 and the insertion hole 111 completely avoids the risk of the needle holder 211 dislodging, guaranteeing the repeatability of the testing action and the long-term stability of the mechanism.

[0075] Example 3:

[0076] The difference between this embodiment and Embodiment 1 is that, please refer to... Figure 6 The housing 11 in this embodiment includes a top plate 112, a bottom plate 113 and several surrounding plates 114. The top plate 112, the bottom plate 113 and the surrounding plates 114 surround to form a cavity. The sensing component 22 is disposed in the cavity, and the linkage component 21 passes through the top plate 112 and moves inside and outside the cavity.

[0077] Specifically, the top plate 112 and the bottom plate 113 are connected by a surrounding plate 114 to form a rigid frame. The linkage component 21 moves up and down through a pre-set circular hole in the top plate 112. The gap between the hole wall of the top plate 112 and the linkage component 21 is controlled within 0.1 mm to limit lateral displacement. The sensing component 22 is fixed above the bottom plate 113, and its sensing surface maintains a vertical distance of 5-8 mm from the end of the linkage component 21, thereby improving detection sensitivity by shortening the signal transmission path. The internal space of the chamber is completely enclosed by the surrounding plate 114, leaving only the movement channel of the linkage component 21, preventing external dust from entering the sensing area.

[0078] In some specific embodiments, a rubber sealing strip may be added between the top plate 112 and the surrounding plate 114 to further isolate liquid splashing; a shock-absorbing pad may be installed under the bottom plate 113 to reduce vibration transmission during equipment operation; and reinforcing ribs may be welded to the outside of the surrounding plate 114 to enhance the overall resistance to deformation.

[0079] Through the above technical solution, the chamber isolation mechanism protects the sensing component 22 from external contamination, achieving physical protection and preventing signal misjudgment caused by environmental factors. Simultaneously, the top plate 112's motion constraint on the linkage component 21 solves the trajectory deviation problem, ensuring position feedback accuracy and significantly improving detection stability. Furthermore, the chamber structure enhances the overall rigidity of the equipment, making it suitable for industrial scenarios involving high-frequency repetitive testing.

[0080] In some embodiments, at least one array of enclosure panels 114 is provided with heat dissipation holes 1141.

[0081] The array is provided with heat dissipation holes 1141, which means that the heat dissipation holes 1141 are arranged in a matrix according to a preset spacing and arrangement rule. Specifically, they can be arranged in an equidistant staggered manner to ensure that the airflow forms a continuous channel between the holes to enhance the convection efficiency.

[0082] Among them, at least one of the side panels 114 refers to the side panels of the lateral support structure constituting the cavity of the shell 11 being perforated. Specifically, the structural strength and heat dissipation requirements can be balanced by retaining the complete form of the remaining side panels 114, thus avoiding a decrease in overall rigidity.

[0083] Specifically, the heat dissipation holes 1141 are evenly distributed on the selected enclosure 114 in a row-column aligned or staggered manner. When the detection mechanism 2 is running, the heat generated inside is exchanged with the outside air through the heat dissipation holes 1141 via convection. The airflow path is guided by a multi-channel array, and the heat continuously diffuses outward from the holes, avoiding the formation of localized high-temperature areas within the cavity. While maintaining the structural stability of the shell 11, the enclosure 114, by limiting the area and density of the openings, prevents insufficient support due to excessive openings, while ensuring a balance between heat dissipation area and airflow efficiency.

[0084] This solution utilizes an array-type porous structure to form a distributed heat dissipation surface, establishing a regular airflow path and significantly improving heat dissipation uniformity. This effectively reduces heat accumulation inside the fixture caused by prolonged testing operations, preventing signal drift or response delay in the sensing component 22 due to high-temperature environments, thus ensuring stable testing accuracy. Furthermore, it eliminates the need for additional active cooling devices, reducing equipment complexity and maintenance costs. It also avoids the problem of localized weakening of the enclosure plate 114 caused by concentrated openings.

[0085] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0086] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0087] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0088] In this application, unless otherwise expressly specified and limited, "above or below" a first feature may include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on" a first feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" a first feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0089] Although the description of this application has been made in conjunction with the specific embodiments described above, it is obvious to those skilled in the art that many substitutions, modifications, and variations can be made based on the above description. Therefore, all such substitutions, modifications, and variations are included within the spirit and scope of the appended claims.
