Description

Technical Field

[0001] This utility model relates to the field of shielding cover installation technology, and in particular to a shielding cover installation and locking device. Background Technology

[0002] Shielding covers are commonly used functional components in electronic devices such as display devices. Their core function is to shield against external electromagnetic interference and protect the delicate internal components of the display device from damage, thereby ensuring the stable operation of the display device. In existing technology, shielding cover installation and fastening equipment is commonly used to install the shielding cover. This equipment includes a screw fastening device. The display device has a mounting cavity. The operator first places the shielding cover into the preset installation position within the mounting cavity of the display device. Then, the operator picks up the screws that match the shielding cover from the material box and inserts them one by one into the mounting holes on the shielding cover, ensuring the screws fall into the corresponding screw holes on the display device. Subsequently, the operator manipulates the screw fastening device to align each screw and tighten it to the preset tightness. After all screws are tightened, a visual inspection is required to check whether the fastening is in place, whether there are any missing screws, or whether any screws are loose. During the process of inserting the screws into the mounting holes on the shielding cover, the screws are easily affected by the operator's hand tremors, visual deviations, or operational fatigue, causing them to fall out of position and into the mounting cavity of the display device. If a screw falls out, it will not only prevent the subsequent screw fastening device from properly aligning with the target hole for tightening, but also require the operator to spend extra time cleaning up the screws that have fallen into the display device and replacing them in order to avoid leaving screws inside the mounting cavity of the display device. This will not improve the installation and fastening efficiency of the shielding cover. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a shielding cover installation and locking device, which is beneficial to improving the installation and locking efficiency of shielding covers.

[0004] The shielding cover installation and locking device according to an embodiment of the present invention includes a frame and a screw locking device, the screw locking device being disposed on the frame. It also includes a positioning fixture for positioning a display device with the shielding cover attached; an auxiliary component with multiple guide tubes, the auxiliary component being used to cover the display device on the positioning fixture, so that the auxiliary component blocks the mounting cavity of the display device, and the multiple guide tubes are respectively connected to multiple mounting holes of the shielding cover, the guide tubes being used to insert screws so that the screws fall into the mounting holes of the shielding cover through the guide tubes; and a screw floating height detection device, disposed on the frame, for detecting the floating height of the screws on the shielding cover.

[0005] It has at least the following beneficial effects: When installing the shielding cover onto the display device, the operator first places the display device on the positioning fixture, allowing the fixture to support and position the display device. Next, the operator places the shielding cover into the mounting cavity of the display device and aligns it with the preset mounting position within the cavity. Then, the operator covers the display device with an auxiliary component on the positioning fixture, ensuring the auxiliary component obscures the mounting cavity and that multiple guide tubes on the auxiliary component extend into the cavity, precisely connecting to the mounting holes of the shielding cover. Subsequently, the operator inserts screws one by one into the guide tubes, which guide the screws as they fall, ensuring they stably enter the mounting holes of the shielding cover and the corresponding screw holes on the display device. After screw insertion, the operator removes the auxiliary component from the display device and operates the screw fastening device to align and tighten each screw to the preset tightness, completing the installation and fastening of the shielding cover. Once the shielding cover is installed and fastened, a screw height detection device is activated to check the screw height on the shielding cover, determining if the screws are properly fastened. During the process of the operator inserting the screws into the mounting holes on the shielding cover, the guide tube on the auxiliary component guides the screw insertion. This not only makes it easier for the operator to insert the screws into the mounting holes on the shielding cover, but also prevents the screws from falling into the mounting cavity of the display device due to operational deviations. It also prevents external debris from entering the mounting cavity of the display device, eliminating the need for the operator to spend extra time cleaning up screws that have fallen into the display device. Therefore, it helps to improve the installation and fastening efficiency of the shielding cover. On the other hand, the screw floating detection device replaces manual visual inspection. It not only effectively avoids the problems of missed detection and misjudgment caused by visual fatigue and subjective judgment errors, but also significantly shortens the time spent on the inspection process. It eliminates the need for the operator to inspect each screw individually, thus also helping to improve the installation and fastening efficiency of the shielding cover.

Detailed Implementation

[0017] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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. Therefore, they should not be construed as limitations on this utility model.

[0018] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0019] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0020] refer to Figure 1 , Figure 3 and Figure 5This utility model discloses a shielding cover installation and locking device, including a frame 500, a screw locking device 300, a positioning fixture 410, an auxiliary component 100, and a screw floating height detection device 200. The screw locking device 300 is mounted on the frame 500; the positioning fixture 410 is used to position and fit the display device 10 with the shielding cover 11 attached; the auxiliary component 100 is provided with multiple guide tubes 150, which are used to cover the display device 10 on the positioning fixture 410, so that the auxiliary component 100 blocks the mounting cavity of the display device 10, and the multiple guide tubes 150 are respectively connected to multiple mounting holes of the shielding cover 11. The guide tubes 150 are used to insert screws, so that the screws fall into the mounting holes of the shielding cover 11 through the guide tubes 150; the screw floating height detection device 200 is mounted on the frame 500, and the screw floating height detection device 200 is used to detect the floating height of the screws on the shielding cover 11 at the installation position.

[0021] Understandably, when installing the shielding cover 11 onto the display device 10, the operator first places the display device 10 onto the positioning fixture 410, so that the positioning fixture 410 supports and positions the display device 10. Next, the operator places the shielding cover 11 to be installed into the mounting cavity of the display device 10 and fits it into the preset mounting position within the mounting cavity. Then, the operator covers the display device 100 onto the positioning fixture 410, so that the auxiliary component 100 covers the mounting cavity of the display device 10, and multiple conduits 150 on the auxiliary component 100 extend into the mounting cavity, with each conduit 150 corresponding to a different mounting point of the shielding cover 11. The holes are precisely connected; then, the operator places the screws one by one into multiple guide tubes 150. The guide tubes 150 guide the screws as they fall, allowing them to fall stably into the mounting holes of the shielding cover 11 and the corresponding screw holes of the display device 10. After the screws are placed, the operator removes the auxiliary component 100 from the display device 10. The operator then operates the screw fastening device 300 to align the screws one by one and tighten them to the preset tightness to complete the installation and fastening of the shielding cover 11. After the installation and fastening of the shielding cover 11 is completed, the screw floating height detection device 200 is activated to detect the floating height of the screws on the shielding cover 11 to determine whether the screws are properly fastened. During the process of the operator inserting the screw into the mounting hole on the shielding cover 11, the guide tube 150 on the auxiliary component 100 guides the screw insertion. This not only makes it easier for the operator to insert the screw into the mounting hole on the shielding cover 11, but also prevents the screw from falling into the mounting cavity of the display device 10 due to operational deviation. It also prevents external debris from entering the mounting cavity of the display device 10, eliminating the need for the operator to spend extra time cleaning up screws that have fallen into the display device 10. Therefore, it helps to improve the installation and fastening efficiency of the shielding cover 11. On the other hand, the screw floating detection device 200 replaces manual visual inspection, which not only effectively avoids the problems of missed detection and misjudgment caused by visual fatigue and subjective judgment errors, but also greatly shortens the time spent on the inspection process. It eliminates the need for the operator to inspect each screw one by one, which also helps to improve the installation and fastening efficiency of the shielding cover 11.

[0022] refer to Figure 3 and Figure 5The auxiliary component 100 is provided with a positioning structure 170, which is used to abut against the inner wall of the mounting cavity of the display device 10. Understandably, after the operator places the auxiliary component 100 onto the display device 10, the positioning structure 170 and multiple guide tubes 150 on the auxiliary component 100 extend into the mounting cavity of the display device 10, and the positioning structure 170 abuts against the inner wall of the mounting cavity, enabling the positioning structure 170 to position the auxiliary component 100. The positioning function of the positioning structure 170 not only prevents the auxiliary component 100 from shifting during screw insertion and tightening, ensuring that the guide tubes 150 are always precisely aligned with the mounting holes of the shielding cover 11, and ensuring that the screws fall stably into the target holes through the guide tubes 150, reducing operational deviations caused by the offset of the auxiliary component 100; on the other hand, the positioning function of the positioning structure 170 also strengthens the shielding effect of the auxiliary component 100 on the mounting cavity, allowing the auxiliary component 100 to be more securely placed on the display device 10, ensuring that there are no gaps in the shielding of the auxiliary component 100, thus preventing screws from falling out and external debris from entering. In one embodiment of the present invention, the positioning structure 170 can be a plurality of positioning blocks disposed on the auxiliary component 100. The distribution shape of the plurality of positioning blocks is the same as the shape of the mounting cavity of the display device 10. The plurality of positioning blocks can abut against the inner wall of the mounting cavity, so that the plurality of positioning blocks play a positioning role in the closing of the auxiliary component 100. In another embodiment of the present invention, the positioning structure 170 can be a positioning protrusion disposed on the auxiliary component 100. The shape of the positioning protrusion is the same as the shape of the mounting cavity of the display device 10. The positioning protrusion can abut against the inner wall of the mounting cavity, so that the positioning protrusion plays a positioning role in the closing of the auxiliary component 100.

[0023] refer to Figures 3 to 5The auxiliary component 100 is provided with multiple guide holes 160, each of which is connected to one end of a plurality of guide tubes 150. The diameter of the guide hole 160 gradually decreases towards the end of the guide tube 150, and the wall of the guide hole 160 can abut against the screw, allowing the screw to slide into the guide tube 150 along the wall of the guide hole 160. It can be understood that, on the one hand, the guiding function of the guide hole 160 significantly reduces the difficulty of aligning the screw during placement; the operator does not need to precisely aim at the opening of the guide tube 150 to place the screw into the guide hole 160, thus reducing the difficulty of screw placement. On the other hand, the tapering wall of the guide hole 160 guides and corrects the screw, correcting slight positional deviations during screw placement, allowing the screw to slide smoothly into the guide tube 150 along the wall, preventing the screw from getting stuck at the entrance of the guide tube 150 or deviating from the guide tube 150 and falling out, further ensuring the accuracy and smoothness of screw placement, thus improving screw placement efficiency. In this embodiment of the invention, the upper end of the conduit 150 is connected to the auxiliary component 100, the lower end of the conduit 150 can be aligned with the mounting hole on the shielding cover 11, and the diameter of the guide hole 160 gradually decreases from top to bottom. (Reference) Figure 3 The auxiliary component 100 is provided with a gripping part 140. The gripping part 140 on the auxiliary component 100 provides the operator with a convenient point of force application, so that the operator can carry the auxiliary component 100 through the gripping part 140, thereby enabling the operator to easily complete the closing and removal operations of the auxiliary component 100.

[0024] refer to Figure 3 The auxiliary component 100 includes a substrate 110 and a transparent plate 120. The substrate 110 has a window, and the transparent plate 120 is connected to the substrate 110 and disposed within the window. One end of a plurality of conduits 150 is connected to the transparent plate 120, and the conduits 150 are made of transparent material. It is understood that the transparent plate 120 allows visualization of the interior of the mounting cavity of the display device 10 through the window of the substrate 110. After the operator covers the display device 100 with the auxiliary component 100, the operator can directly observe the alignment of the conduits 150 with the mounting holes of the shielding cover 11 through the transparent plate 120, ensuring precise connection before inserting the screw. On the other hand, the transparent material of the conduits 150 allows the operator to observe in real time the screw's slippage within the conduits 150 and whether it successfully falls into the target hole, enabling the operator to promptly detect screw jamming, misalignment, or other problems and quickly adjust accordingly, reducing rework caused by inaccurate alignment of the conduits 150 or abnormal screw insertion.

[0025] refer to Figure 3 and Figure 4The auxiliary component 100 also includes a locking assembly 130, which is disposed on the substrate 110. The transparent plate 120 includes a first part 121 and a second part 122. The first part 121 is connected to the substrate 110. One end of the second part 122 is hinged to the first part 121. The other end of the second part 122 can be fixed to the substrate 110 by the locking assembly 130. One end of each of the plurality of conduits 150 is connected to the second part 122. Understandably, one end of the second part 122 is hinged to the first part 121, and one end of each of the multiple conduits 150 is connected to the second part 122, enabling the conduit 150 installation area to be openable and adjustable. When the operator closes the auxiliary part 100, the second part 122 can be opened first to visually align the conduit 150 with the mounting hole of the shield 11, and then the second part 122 can be fixed by the locking assembly 130. This greatly reduces the difficulty of aligning the conduit 150 and ensures that the conduit 150 is accurately connected to the mounting hole on the shield 11. After the conduit 150 is aligned, the locking assembly 130 can fix the other end of the second part 122, so that the second part 122 is fixed on the base plate 110, avoiding the displacement of the conduit 150 caused by the shaking of the second part 122 during screw insertion and tightening, and ensuring the stability of screw insertion. On the other hand, when cleaning the conduit 150, checking the patency of the conduit 150, or performing maintenance, the locking component 130 can be unlocked to open the second part 122 and directly contact the conduit 150 without disassembling the entire auxiliary component 100, making cleaning and maintenance more convenient and efficient. It can quickly remove residual impurities or stuck screws inside the conduit 150, preventing the conduit 150 from becoming blocked and affecting its use.

[0026] In this invention, the gripping part 140 is disposed on the base plate 110, the guide hole 160 is disposed on the second part 122, and one end of the second part 122 is hinged to the first part 121 via a hinge. The locking assembly 130 can be a common pin locking assembly 130 or a common snap-on locking assembly 130, which will not be further described here.

[0027] It should be explained that screw float height is a key installation quality indicator. Screw float height refers to the vertical distance between the screw head and the surface of the connected component (shielding cover 11). If the float height exceeds the preset range, it may lead to problems such as loose connections, poor conductivity, and uneven structural stress, thereby reducing the product yield. In this utility model, after the screw is tightened, the screw head is pressed against the surface of the shielding cover 11.

[0028] refer to Figure 1 and Figure 2The screw floating height detection device 200 includes a lifting drive and a floating height detection module 210. The lifting drive is mounted on a frame 500, and its output end is connected to the floating height detection module 210. The floating height detection module 210 has multiple probes 220. The lifting drive can drive the floating height detection module 210 to descend, so that the multiple probes 220 respectively abut against the heads of multiple screws on the shield 11. It can be understood that after the shield 11 is installed and locked, the lifting drive starts and drives the floating height detection module 210 to descend, so that the multiple probes 220 of the floating height detection module 210 smoothly abut against the heads of multiple screws. The lifting drive stops descending, and then the floating height detection module 210 starts detecting and calculating the floating height data. After the detection is completed, the lifting drive drives the floating height detection module 210 to rise and reset, and the probes 220 disengage from the screw heads, thus completing the floating height detection of the screw. In this embodiment of the invention, the lifting drive can be a common lifting cylinder.

[0029] In this embodiment of the invention, the buoyancy detection module 210 further includes a built-in processor and multiple displacement sensors. The multiple displacement sensors are used to detect the displacement of multiple probes 220, and the built-in processor is used to receive data transmitted from the multiple displacement sensors. First, a reference position calibration is performed. Before the shielding cover 11 is installed and locked by the shielding cover installation and locking device, the lifting drive component lowers the buoyancy detection module 210, causing the multiple probes 220 of the buoyancy detection module 210 to contact a preset reference plane at the installation station. This reference plane simulates the standard height of the shielding cover 11 surface. At this time, the built-in processor records the specific data of the multiple probes 220 at this reference plane position, using it as a reference for subsequent buoyancy calculations to ensure a consistent comparison standard for each detection. When the lifting drive component lowers the buoyancy detection module 210, the multiple probes 220 smoothly contact the surfaces of multiple screw heads. Here, only one displacement sensor and probe 220 are used as an example. Because the screw has a floating height (i.e., a vertical distance between the screw head and the surface of the shield 11), the position of the probe 220 when it contacts the screw head will be higher than the previously calibrated reference plane position. At this time, the displacement sensor will capture the vertical displacement change of the probe 220 from the reference plane position to the position where it contacts the screw head in real time, collect the specific value of this displacement, and transmit the collected displacement data to the built-in processor in real time. After receiving the data transmitted by the displacement sensor, the built-in processor will calculate according to the preset algorithm. Since the vertical displacement of the probe 220 is exactly equal to the vertical distance between the screw head and the product surface (i.e., the screw floating height), the built-in processor will directly convert the displacement data into the corresponding floating height value. If the calculated floating height value exceeds the preset acceptable range, the built-in processor will immediately issue a warning signal, and at the same time transmit the floating height value, the corresponding screw coordinate position, and the qualified status of the detection data to the main control system of the shield installation and fastening equipment. This facilitates the subsequent storage and archiving of the detection data and also facilitates the rapid screening of products with unqualified floating height, ensuring product quality. The method of detecting floating height by the cooperation of the probe 220 and the displacement sensor is quite common and will not be elaborated further here.

[0030] refer to Figure 1 and Figure 6The screw fastening device 300 includes an electric screwdriver bit 310, an assisting arm 320, and a screw feeding mechanism 330. The screw feeding mechanism 330 and the assisting arm 320 are both mounted on the frame 500, and the movable end of the assisting arm 320 is connected to the electric screwdriver bit 310. Understandably, when the operator needs to install the shielding cover 11 on the display device 10, the operator first places the display device 10 on the positioning fixture 410 for support and positioning. Then, the operator places the shielding cover 11 into the mounting cavity of the display device 10 and fits it into the preset installation position. Subsequently, the operator covers the display device 10 with an auxiliary component 100 equipped with multiple guide tubes 150, so that the auxiliary component 100 covers the mounting cavity and the guide tubes 150 are precisely connected to the mounting holes of the shielding cover 11. After that, the operator takes the appropriate screws from the screw feeding mechanism 330 and puts them one by one into the guide tubes 150 of the auxiliary component 100. The screws fall stably into the mounting holes of the shielding cover 11 and the corresponding screw holes of the display device 10 through the guide tubes 150 to complete the screw placement. After the screws are fed in, the operator removes the auxiliary component 100 from the display device 10. Then, the operator holds the electric screwdriver bit 310 connected to the movable end of the assist arm 320. Utilizing the adjustable angle and height of the assist arm 320, the operator precisely aligns the electric screwdriver bit 310 with the screw in the mounting hole, and starts the electric screwdriver bit 310 to tighten the screw to the preset tightness. The position of the electric screwdriver bit 310 is then adjusted using the assist arm 320, and the alignment and tightening steps are repeated for each of the remaining screws until all screws are properly tightened, thus completing the installation and tightening of the shielding cover 11. After the installation and tightening of the shielding cover 11 is completed, the screw floating height detection device 200 is activated to detect the floating height of the screws on the shielding cover 11 to determine whether the screws are properly tightened. In this embodiment of the invention, the electric screwdriver bit 310, the assist arm 320, and the screw feeding mechanism 330 are all common configurations in the field of screw tightening, and will not be further described here.

[0031] refer to Figure 1The shielding cover installation and fastening equipment also includes a conveying device 400. The frame 500 is provided with an installation station. The conveying device 400 is located on the frame 500. The conveying device 400 is used to convey the positioning fixture 410 from back to front so that the positioning fixture 410 can be moved to the installation station. The screw floating height detection device 200 is used to detect the floating height of the screws on the shielding cover 11 at the installation station. Understandably, the upstream workers of the shielding cover installation and fastening equipment first place the display device 10 of the shielding cover 11 to be installed on the positioning fixture 410. Then, the workers place the positioning fixture 410 carrying the display device 10 on the conveying device 400. The positioning fixture 410 is smoothly conveyed from back to front by the conveying device 400 until it moves to the installation station. Next, the operator places the shielding cover 11 into the installation cavity of the display device 10 at the installation station and fits it into the preset installation position. Then, the auxiliary component 100, equipped with multiple conduits 150, is placed over the display device 10, so that the auxiliary component 100 covers the installation cavity and the multiple conduits 150 are precisely connected to the installation holes of the shielding cover 11. Subsequently, the operator... The wire feeding mechanism 330 picks up the matching screws and places them one by one into the guide tube 150. The screws are guided by the guide tube 150 and fall stably into the mounting holes of the shielding cover 11 and the corresponding screw holes of the display device 10. After the screws are placed, the operator removes the auxiliary part 100. Then, the operator uses the electric screwdriver bit 310 to tighten the screws one by one to the preset tightness. After the shielding cover 11 is installed and locked, the screw floating height detection device 200 detects the floating height of the screws on the shielding cover 11 to determine whether the locking is in place. After the detection is completed, the conveying device 400 continues to convey the positioning fixture 410 and the display device 10 with the shielding cover 11 installed forward, so that the display device 10 with the shielding cover 11 installed can enter the downstream equipment to carry out subsequent processes.

[0032] In this embodiment of the utility model, the conveying device 400 includes two belt conveying mechanisms, both of which are mounted on the frame 500. The two belt conveying mechanisms abut against the two sides of the positioning fixture 410, so that the two belt conveying mechanisms can simultaneously convey the positioning fixture 410 from back to front.

[0033] In this embodiment of the invention, the shielding cover installation and locking device further includes a limiting device (not shown in the figure). The limiting device is mounted on the frame 500 and can abut against the positioning fixture 410 on the conveying device 400, so that the positioning fixture 410 stops at the installation position. It is understood that when the conveying device 400 conveys the positioning fixture 410 to the installation position, the limiting device abuts against the positioning fixture 410 to counteract the forward movement tendency of the positioning fixture 410 caused by the conveying inertia, and to prevent the positioning fixture 410 from deviating from the preset installation position due to inertia overshoot. This ensures that the positioning fixture 410 stops accurately and stably at the installation position, providing a reliable positioning reference for subsequent processes such as auxiliary component 100 cover fitting, conduit 150 alignment, screw fastening, and float detection, and ensuring the accuracy and stability of the overall installation and locking. As an embodiment of this utility model, the limiting device includes two limiting cylinders. The cylinder bodies of the two limiting cylinders are connected to the frame 500. The two limiting cylinders are respectively configured to correspond to two belt conveyor mechanisms.
