Abstract
Description
Technical Field
[0001] This application relates to the field of monitor bracket testing fixture technology, and in particular to a bracket testing fixture. Background Technology
[0002] In related technologies, the connection between the monitor stand and the chassis often uses a quick-release screw structure for fastening. The traditional method involves one operator assembling the stand and chassis and holding it by hand, while another operator uses an electric lock to tighten the quick-release screws connecting the stand and chassis. During the tightening process, issues such as shallow threaded holes at the bottom of the stand causing the screw heads to protrude or stripping occur, ultimately resulting in defective products reaching customers, leading to complaints and fines. To avoid these problems and save labor costs, it is necessary to inspect the threaded holes at the bottom of the stand for excessively shallow holes or stripped threads. Utility Model Content
[0003] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this application proposes a bracket inspection fixture that can automatically detect whether the threaded holes at the bottom of the bracket are qualified, thereby reducing defects and labor costs.
[0004] According to a first aspect embodiment of the present invention, a bracket testing fixture includes: a workbench, a positioning component, an electric screwdriver testing mechanism, a second sensing mechanism, and an alarm mechanism. The workbench has a mounting position for mounting a chassis and a clearance hole located at the mounting position. The positioning component is disposed on the workbench and is used to position the edge of the chassis to prevent the chassis from detaching from the workbench. The electric screwdriver testing mechanism is disposed below the workbench and includes a first sensor, an electric screwdriver assembly, and a first driving component. The electric screwdriver assembly is correspondingly disposed below the clearance hole and is used to attach or remove locking components to the chassis and the bracket. The output end of the first driving component is connected to the electric screwdriver assembly and is used to drive the electric screwdriver assembly to rise. In this system, when the first sensor detects the trigger end of the electric screwdriver assembly, the first drive component stops driving; the second sensing mechanism is located on the workbench and includes a second sensor for sensing the bracket; the alarm mechanism is electrically connected to the first sensor and the second sensing mechanism respectively; wherein, when the threaded hole at the bottom of the bracket is too shallow or stripped, the locking component cannot lock the bracket and the chassis, so that the second sensor detects the through hole at the bottom of the bracket, and the alarm mechanism indicates a malfunction; when the length and thread shape of the threaded hole at the bottom of the bracket are qualified, the locking component pulls the bracket tight to the chassis, the second sensor cannot detect the through hole at the bottom of the bracket and is blocked by the bracket, and the alarm mechanism indicates a pass.
[0005] The bracket detection fixture according to the embodiments of this utility model has at least the following beneficial effects: This bracket detection fixture includes a workbench, a positioning component, an electric screwdriver detection mechanism, a second sensing mechanism, and an alarm mechanism. In use, the chassis is first fixed to the mounting position on the workbench using the positioning component. Then, the bracket is inserted into the chassis, ensuring that the threaded hole at the bottom of the bracket corresponds to the through hole on the chassis. A locking component is placed on the upper end of the electric screwdriver assembly of the electric screwdriver detection mechanism below the workbench, aligning the locking component with the clearance hole on the workbench and the through hole on the chassis. Next, the electric screwdriver detection mechanism is activated, and the electric screwdriver assembly rises under the drive of the first driving component, locking the locking component to the base plate and the bracket. When the trigger end of the electric screwdriver assembly passes the first sensor, the first driving component stops driving. At this time, if the height of the threaded hole at the bottom of the bracket is qualified, the bracket descends under the locking and tightening action of the locking component, so that the second sensor on the workbench is blocked by the bracket and cannot detect the lower part of the bracket. If the threaded hole at the bottom of the bracket is too shallow, after the electric screwdriver assembly is locked, although the electric screwdriver assembly stops clamping and rotating the locking member, it will continue to rise under the drive of the first drive member until the trigger end of the electric screwdriver assembly stops rising after passing the first sensor. At this time, because the bracket is not pulled down tightly to the chassis, and because the edge of the chassis is restricted to the worktable by the positioning component and cannot be detached, the chassis and bracket are in a state of being lifted and deformed in the middle by the electric screwdriver assembly. At this time, the second sensor detects the through hole at the bottom of the bracket, and the alarm mechanism indicates a defect. If the threaded hole at the bottom of the bracket is stripped, the locking member will also fail to lock in place, which will also cause the electric screwdriver assembly to lift the bracket and chassis to deformation, and the second sensor will detect the through hole at the bottom of the bracket, thus indicating a defect. In summary, the bracket inspection fixture of this application can automatically detect whether the threaded hole at the bottom of the bracket is qualified, thereby reducing the occurrence of defects and reducing labor costs.
[0006] According to some embodiments of the present invention, the electric screwdriver detection mechanism further includes a third sensor, the first driving member is used to drive the electric screwdriver assembly to rise and fall, and the third sensor is located below the first sensor; wherein, when the electric screwdriver assembly disassembles the locking member and descends to the point where the third sensor senses the trigger end of the electric screwdriver assembly, the first driving member stops driving.
[0007] According to some embodiments of the present invention, a control system is also included, which is electrically connected to the first sensor, the second sensor and the third sensor respectively; wherein, when the bracket is inserted into the chassis, the second sensor transmits the sensed signal to the control system, and the control system controls the first driving member to drive the electric screwdriver assembly to rise and lock the locking member to the chassis and the bracket.
[0008] According to some embodiments of the present invention, the second sensing mechanism further includes an adjustment component, which is connected to the second sensor and the worktable, and is used to adjust the height of the second sensor and / or its distance from the support to adapt to different specifications of supports and / or chassis.
[0009] According to some embodiments of the present invention, the adjustment assembly includes a vertical plate and a first locking assembly. The vertical plate is provided with a first strip hole extending in the vertical direction, and the second sensor is provided with a first mounting hole. The first locking assembly connects the second sensor and the vertical plate through the first mounting hole and the first strip hole.

[0012] According to some embodiments of the present invention, the positioning component includes a fixing plate and a third locking component. The fixing plate is located outside the clearance hole on the worktable and forms an installation position with the upper surface of the worktable. The third locking component connects and locks the fixing plate and the worktable.
[0013] According to some embodiments of the present invention, a heat dissipation mechanism is also included, which is disposed below the workbench and facing the electric screwdriver assembly for heat dissipation.

[0028] The following is for reference. Figures 1 to 4 This invention describes a bracket testing fixture according to an embodiment of the present invention.
[0029] like Figures 1 to 3 As shown, the bracket testing fixture according to an embodiment of the present invention includes: a workbench 100, a positioning component 200, an electric screwdriver testing mechanism 300, a second sensing mechanism 400, and an alarm mechanism 500. The workbench 100 is provided with a mounting position for mounting a chassis 700 and a clearance hole 110 located at the mounting position; the positioning component 200 is disposed on the workbench 100 and is used to position the edge of the chassis 700 to prevent the chassis 700 from detaching from the workbench 100; the electric screwdriver testing mechanism 300 is disposed below the workbench 100 and includes a first sensor 310, an electric screwdriver assembly 320, and a first driving member 330. The electric screwdriver assembly 320 is correspondingly disposed below the clearance hole 110 and is used to lock or remove locking members to the chassis 700 and the bracket 800. The output end of the first driving member 330 is connected to the electric screwdriver assembly 320 and is used to drive the electric screwdriver assembly 320 to rise; wherein, when When the first sensor 310 senses the trigger end 3211 of the electric screwdriver assembly 320, the first drive member 330 stops driving; the second sensing mechanism 400 is disposed on the workbench 100 and includes a second sensor 410 for sensing the bracket 800; the alarm mechanism 500 is electrically connected to the first sensor 310 and the second sensing mechanism 400 respectively; wherein, when the threaded hole at the bottom of the bracket 800 is too shallow or stripped, the locking member cannot lock the bracket 800 and the chassis 700, so that the second sensor 410 senses the through hole 810 at the bottom of the bracket 800, and the alarm mechanism 500 indicates a malfunction; when the length and thread shape of the threaded hole at the bottom of the bracket 800 are qualified, the locking member pulls the bracket 800 tight onto the chassis 700, the second sensor 410 cannot sense the through hole 810 at the bottom of the bracket 800 and is blocked by the bracket 800, and the alarm mechanism 500 indicates a qualified result.
[0030] Understandably, this bracket testing fixture includes a workbench 100, a positioning component 200, an electric screwdriver testing mechanism 300, a second sensing mechanism 400, and an alarm mechanism 500. In use, the chassis 700 is first fixed to the mounting position on the workbench 100 using the positioning component 200. Then, the bracket 800 is inserted into the chassis 700, ensuring that the threaded hole at the bottom of the bracket 800 aligns with the through hole in the chassis 700. A locking component is placed on the upper end of the electric screwdriver component 320 of the electric screwdriver testing mechanism 300 below the workbench 100, aligning the locking component with the clearance hole 110 and the bottom of the workbench 100. The through hole of disc 700 is then opened. Next, the electric screwdriver detection mechanism 300 is activated. The electric screwdriver assembly 320 rises under the drive of the first drive member 330, allowing it to lock the locking member to the base plate and bracket 800. When the trigger end 3211 of the electric screwdriver assembly 320 passes the first sensor 310, the first drive member 330 stops driving. At this time, if the height of the threaded hole at the bottom of the bracket 800 is acceptable, the bracket 800 descends under the locking and tightening action of the locking member, so that the second sensor 410 on the worktable 100 is blocked by the bracket 800 and cannot detect the through hole 81 at the bottom of the bracket 800. 0. At this time, the alarm mechanism 500 indicates that it is qualified; if the height of the threaded hole at the bottom of the bracket 800 is too shallow, after the electric screwdriver assembly 320 is locked, although the electric screwdriver assembly 320 stops clamping and rotating the locking member, it will continue to rise under the drive of the first drive member 330 until the trigger end 3211 of the electric screwdriver assembly 320 stops rising after passing the first sensor 310. At this time, since the bracket 800 is not pulled down tightly onto the chassis 700, and since the edge of the chassis 700 is restricted to the worktable 100 by the positioning component 200 and cannot be detached, the chassis 700 and the bracket 800 are in a state of being controlled by the electric screwdriver assembly 320. When the bracket is lifted to a state of arched deformation in the middle, the second sensor 410 detects the through hole 810 at the bottom of the bracket 800, and the alarm mechanism 500 indicates a defect. If the threaded hole at the bottom of the bracket 800 is stripped, the locking part will also fail to lock in place, which will also cause the electric screwdriver assembly 320 to lift the bracket 800 and the chassis 700 to deformation, and the second sensor 410 will detect the through hole 810 at the bottom of the bracket 800, thus indicating a defect. In summary, the bracket testing fixture of this application can automatically detect whether the threaded hole at the bottom of the bracket 800 is qualified, thereby reducing the occurrence of defects and reducing labor costs.
[0031] The chassis 700 has an insertion part at the top and the bracket 800 has a cavity at the bottom, so that when the bracket 800 is inserted into the chassis 700, the insertion part is aligned with the insertion cavity, thereby preventing the bracket 800 from moving horizontally during the locking process.
[0032] Understandably, the electric screwdriver detection mechanism 300 also includes a third sensor 340, and the first drive member 330 is used to drive the electric screwdriver assembly 320 to rise and fall. The third sensor 340 is located below the first sensor 310. Specifically, when the electric screwdriver assembly 320 disengages the locking member and descends to the point where the third sensor 340 senses the trigger end 3211 of the electric screwdriver assembly 320, the first drive member 330 stops driving. For example, as... Figure 3 As shown, in this embodiment, after the alarm mechanism 500 alarms for a period of time, the electric screwdriver assembly 320 descends under the drive of the first drive member 330. At the same time, the electric screwdriver assembly 320 reverses to loosen the locking member until the trigger end 3211 of the electric screwdriver assembly 320 enters the third sensor 340. Then, the first drive member 330 stops driving. At this time, the bracket 800 can be removed from the chassis 700 and classified according to whether it is qualified. At the same time, the position of the trigger end 3211 in the third sensor 340 also serves as the initial state for the electric screwdriver assembly 320 to perform the next locking test.
[0033] It is understood that a control system is also included, which is electrically connected to the first sensor 310, the second sensor 410, and the third sensor 340 respectively. When the bracket 800 is inserted into the chassis 700, the second sensor 410 transmits the sensed signal to the control system. The control system then controls the first drive unit 330 to drive the electric screwdriver assembly 320 upwards and lock the locking member to the chassis 700 and the bracket 800. For example, in this embodiment, by electrically connecting the first sensor 310, the second sensor 410, and the third sensor 340 to the control system, and when the bracket 800 is inserted into the chassis 700, the second sensor 410 can sense the bracket 800 and transmit the sensed signal to the control system. Subsequently, the control system controls the first drive unit 330 to drive the electric screwdriver assembly 320 upwards for testing, thus achieving automated start-up of the test.
[0034] It should be understood that, in addition to the automated test initiation method described above, in other embodiments, the test can also be started manually by controlling the control system.
[0035] It is understood that the second sensing mechanism 400 also includes an adjustment component, which connects the second sensor 410 and the worktable 100, and is used to adjust the height and / or distance of the second sensor 410 from the support 800 to accommodate different sizes of the support 800 and / or chassis 700. For example, as Figure 4As shown, in this embodiment, due to the different specifications of the bracket 800, the height of the through hole 810 at the bottom of the bracket 800 may also be different. Therefore, in order to adapt to the height of the through hole 810 of different brackets 800, the adjustment component connecting the second sensor 410 and the worktable 100 can adjust the height of the second sensor 410. In addition, the width of the chassis 700 may also be different due to different specifications. Therefore, in order to adapt to chassis 700 of different widths, the distance of the second sensor 410 from the bracket 800, that is, from the chassis 700, can also be adjusted by the adjustment component.
[0036] It is understood that the adjustment assembly includes a vertical plate 420 and a first locking assembly. The vertical plate 420 has a first strip-shaped hole 421 extending vertically, and the second sensor 410 has a first mounting hole. The first locking assembly connects the second sensor 410 and the vertical plate 420 through the first mounting hole and the first strip-shaped hole 421. For example, as... Figure 4 As shown, in this embodiment, the adjustment component specifically includes a vertical plate 420 and a first locking component. By aligning the first mounting hole of the second sensor 410 with different heights of the first strip hole 421 of the vertical plate 420, and locking the connection through the first locking component, the height of the second sensor 410 can be adjusted.
[0037] Understandably, the adjustment mechanism also includes a horizontal plate 430 and a second locking assembly. The horizontal plate 430 is connected to the vertical plate 420. The horizontal plate 430 has a second strip-shaped hole 431 extending horizontally away from the chassis 700. The worktable 100 has a second mounting hole 120. The second locking assembly connects the horizontal plate 430 and the worktable 100 through the second mounting hole 120 and the second strip-shaped hole 431. For example, as... Figure 4 As shown, in this embodiment, by aligning the strip hole of the horizontal plate 430 with the second mounting hole 120 on the worktable 100 and connecting and locking it with the second locking assembly, the horizontal distance between the second sensor 410 and the chassis 700 can be adjusted.
[0038] Understandably, the electric screwdriver detection mechanism 300 also includes a fixing member 350, an electric screwdriver assembly 320 disposed on the fixing member 350 and including a sliding member 321 and an electric screwdriver 322, a first sensor 310 and a third sensor 340 respectively disposed on the fixing member 350, and a sliding member 321 for mounting the electric screwdriver 322 and having a trigger end 3211. For example, as Figure 2As shown, in this embodiment, the electric screwdriver detection mechanism 300 is provided with a fixing member 350 fixed to the bottom of the workbench 100. The first driving member 330 is provided on the fixing member 350 and is used to drive the electric screwdriver assembly 320 to move up and down along the fixing member 350. The electric screwdriver assembly 320 includes a sliding member 321 and an electric screwdriver 322 installed on the sliding member 321. The sliding member 321 is provided with a trigger end 3211 that can slide between the first sensor 310 and the third sensor 340.
[0039] It is understood that the positioning assembly 200 includes a fixing plate and a third locking assembly. The fixing plate is located outside the clearance hole 110 on the worktable 100 and forms a mounting position with the upper surface of the worktable 100. The third locking assembly connects and locks the fixing plate and the worktable 100. For example, as Figure 1 As shown, in this embodiment, a fixing plate and a third locking assembly are provided on the outside of the clearance hole 110 on the workbench 100. An installation position is formed between the bottom of the fixing plate and the upper part of the workbench 100 so that the chassis 700 can be horizontally inserted into the installation position. The third locking assembly locks the fixing plate and the workbench 100 together.
[0040] Understandably, it also includes a heat dissipation mechanism 600, which is located below the workbench 100 and faces the electric screwdriver assembly 320 for heat dissipation. For example, as Figure 2 As shown, in this embodiment, the heat dissipation mechanism 600 dissipates heat from the electric screwdriver detection mechanism 300, thereby improving the ambient temperature and thus extending its service life.
[0041] It is understandable that the alarm system 500 uses indicator lights. For example, ... Figure 1 As shown, in this embodiment, the alarm mechanism 500 is a signal light. The signal light is green to indicate that the threaded hole at the bottom of the bracket 800 is qualified, and the signal light is red to indicate that the threaded hole at the bottom of the bracket 800 is unqualified: too shallow or stripped.
[0042] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
