[0009] Through the above technical scheme, in actual application, the worker abuts one end of the LED frame to one of the positioning strips and abuts one side of the LED frame to the other positioning strip to realize the positioning and placement of the LED frame, so that each detection head is aligned with the mounting position of each screw on the LED frame. The detection head detects whether the corresponding position is installed with a screw, if no screw is detected, the detection head transmits a detection signal to the controller, the controller receives the detection signal and controls the defective display lamp to light, so that the detection is automatically completed, and the accuracy of detection is effectively improved, thereby reducing the situation of missing detection.

[0010] Preferably, the positioning strip is detachably connected to the case.

[0011] By adopting the above technical solution, and by setting the positioning strips to be detachably connected to the chassis, the positioning strips can be replaced, ensuring that when the LED frame abuts against the two positioning strips, the installation positions of each detection head and each screw on the LED frame correspond, thereby improving the accuracy of the detection.

[0012] Preferably, the positioning assembly further includes a plurality of fastening bolts, the lower ends of which pass through the positioning strip and are threaded to the housing, and the upper ends of which abut against the upper side of the positioning strip.

[0014] Preferably, the upper side of the positioning strip is provided with a countersunk hole, and the upper end of the fastening bolt is embedded in the countersunk hole.

[0015] By adopting the above technical solution and setting countersunk holes, the upper end of the fastening bolt is located on the upper side of the positioning strip, which improves the overall aesthetics of the detection device and reduces the possibility of injury to workers caused by the fastening bolts.

[0019] By adopting the above technical solution and setting a contact switch, when one side of the LED frame abuts against the positioning strip, the LED frame abuts against the contact switch, so that the detection component is in working state, which can effectively save power.

[0026] Preferably, the spring is sleeved on the sliding rod.

[0027] By adopting the above technical solution and setting a spring sleeve on the sliding rod, the spring can be prevented from being damaged due to excessive bending.

[0029] 1. In practical applications, the operator places one end of the LED frame against one of the positioning strips and another side against the other positioning strip to position the LED frame. This ensures that each detection head is aligned with the installation position of each screw on the LED frame. The detection head checks whether a screw is installed at the corresponding position. If no screw is detected, the detection head transmits a detection signal to the controller. The controller receives the detection signal and controls the fault indicator light to illuminate, thus automatically completing the detection and effectively improving the accuracy of the detection, thereby reducing missed detections.

[0030] 2. By setting the connector and spring, the LED frame can abut against the contact switch in advance during the process of the LED frame abutting against the positioning bar, so as to ensure the detection work of the detection component.

[0037] The following is in conjunction with the appendix Figures 2-4 This application will be described in further detail.

[0038] This application discloses a testing device for LED frames.

[0039] Example 1:

[0040] Reference Figure 2 and Figure 3 The detection device includes a chassis 1, a positioning component 2 and a detection component 3. The chassis 1 is a rectangular box, and multiple mounting holes 11 are provided on the upper side of the chassis 1.

[0041] The positioning component 2 includes two positioning strips 21, which are fixedly connected to the upper side of the chassis 1. One positioning strip 21 is set along the length direction of the chassis 1, and the other positioning strip 21 is set along the width direction of the chassis 1, so that the two positioning strips 21 are perpendicular to each other.

[0042] The detection assembly 3 includes multiple detection heads 31, defect indicator lights 32, and a controller (not shown in the figure). The number of detection heads 31 is the same as the number of mounting holes 11. Each detection head 31 is installed in its respective mounting hole 11, and the detection head 31 is flush with or slightly lower than the upper side of the chassis 1. The defect indicator lights 32 are fixedly connected to the upper side of the chassis 1. The controller is installed in the chassis 1 and is electrically connected to the multiple detection heads 31 and the defect indicator lights 32.

[0043] In practical applications, the operator places one end of the LED frame 4 against the inside of one of the positioning strips 21, and another side of the LED frame 4 against the inside of the other positioning strip 21 to position the LED frame 4. This ensures that each detection head 31 is aligned with the installation position of each screw on the LED frame 4. The detection head 31 then operates to detect whether a screw is installed at the corresponding position. If no screw is detected, the detection head 31 transmits a detection signal to the controller. The controller receives the detection signal and controls the fault indicator light 32 to illuminate to remind the operator. This automatic detection effectively improves the accuracy and efficiency of the detection, thereby reducing missed detections.

[0044] In some embodiments, both positioning strips 21 can be detachably connected to the housing 1. Since there may be errors in the installation of the detection head 31, the size of the positioning strip 21 and the size of the LED frame 4, the positioning strip 21 of appropriate size can be replaced to ensure that when the LED frame 4 abuts against the two positioning strips 21, the installation position of each detection head 31 corresponds to the installation position of each screw on the LED frame 4, thereby improving the accuracy of detection.

[0045] In some embodiments, the positioning assembly 2 further includes a plurality of fastening bolts 22, the lower end of which passes through the positioning strip 21 and is threaded to the housing 1, and the upper end of which abuts against the upper side of the positioning strip 21, so as to realize the detachable connection of the positioning strip 21. The structure is simple and easy to operate, thereby facilitating the installation and removal of the positioning strip 21.

[0046] In some embodiments, a countersunk hole 211 is provided on the upper side of the positioning strip 21, and the upper end of the fastening bolt 22 is embedded in the countersunk hole 211, so that the upper end of the fastening bolt 22 is located on the upper side of the positioning strip 21, thereby improving the overall aesthetics of the detection device. During the use of the detection device, the fastening bolt 22 can be kept away from contact with the workers as much as possible, thereby reducing the possibility of injury to the workers caused by the fastening bolt 22.

[0047] In some embodiments, the lower side of the positioning strip 21 protrudes to form a plurality of positioning posts 212, and correspondingly, the upper side of the housing 1 is provided with a plurality of positioning holes 12. Each positioning post 212 is inserted into each positioning hole 12 to realize the positioning installation of the positioning strip 21, so as to ensure the accurate placement of the LED frame 4 and thus ensure the accuracy of the detection.

[0048] The implementation principle of this embodiment is as follows: In practical application, the operator abuts one end of the LED frame 4 against the inside of one of the positioning strips 21, and one side of the LED frame 4 against the inside of another positioning strip 21 to achieve the positioning of the LED frame 4. This allows each detection head 31 to be aligned with the installation position of each screw on the LED frame 4. The detection head 31 operates to detect whether a screw is installed at the corresponding position. If no screw is detected, the detection head 31 transmits the detection signal to the controller. The controller receives the detection signal and controls the fault indicator light 32 to light up to remind the operator. In this way, the detection can be completed automatically, which can effectively improve the accuracy and efficiency of the detection, thereby reducing the situation of missed detection.

[0049] Example 2:

[0050] Reference Figure 4 This embodiment is identical to Embodiment 1 in all other structural aspects, except that the detection component 3 further includes a contact switch 33. The contact switch 33 is located inside one of the positioning bars 21 for the LED frame 4 to abut against, and is electrically connected to the controller. In practical applications, one side of the LED frame 4 abuts against the positioning bar 21 and simultaneously against the contact switch 33. At this time, the contact switch 33 transmits an abutment signal to the controller, causing the controller to operate, thus putting the detection component 3 into a working state. That is, the detection component 3 only operates when the LED frame 4 abuts against the contact switch 33, effectively saving power.

[0051] In some embodiments, the positioning assembly 2 further includes a connector 34 and a spring 35. The connector 34 includes a sliding rod 341 and a connecting plate 342. The sliding rod 341 is slidably connected to the positioning strip 21, and the sliding direction is perpendicular to the positioning strip 21. The contact switch 33 is fixedly connected to one end of the sliding rod 341 and can extend into the interior of the positioning strip 21 under the abutment of the LED frame 4. The connecting plate 342 is fixedly connected to the other end of the sliding rod 341. One end of the spring 35 is fixedly connected to the outside of the positioning strip 21, and the other end is fixedly connected to the connecting plate 342 to drive the sliding rod 341 to move inward, thereby causing the contact switch 33 to move inward.

[0052] During the process of the LED frame 4 abutting against the positioning bar 21, the spring 35 drives the sliding rod 341 to move inward, causing the contact switch 33 to extend out of the positioning bar 21. The LED frame 4 can abut against the contact switch 33 in advance to ensure the detection work of the detection component 3. When the LED frame 4 abuts against the two positioning bars 21, the LED frame 4 is completely located on the upper side of the housing 1 to ensure placement stability. This makes it inconvenient to apply force to remove the LED frame 4. The spring 35 drives the sliding rod 341 to slide, moving the LED frame 4 away from the corresponding positioning bar 21, so that the LED frame 4 is partially detached from the housing 1, thus making it easier to remove the LED frame 4.

[0053] In some embodiments, the connecting plate 342 is threadedly connected to the sliding rod 341, and can adjust the initial position of the sliding rod 341, that is, can adjust the position of the contact switch 33 to suit different working conditions.

[0054] In some embodiments, the spring 35 is sleeved on the sliding rod 341 to avoid excessive bending and damage to the spring 35, thereby improving the service life of the spring 35.

[0055] The implementation principle of this embodiment is as follows: During the process of the LED frame 4 abutting against the positioning bar 21, the spring 35 drives the sliding rod 341 to move inward, causing the contact switch 33 to extend out of the positioning bar 21. The LED frame 4 can abut against the contact switch 33 in advance to ensure the detection work of the detection component 3. When the LED frame 4 abuts against the two positioning bars 21, the LED frame 4 is completely located on the upper side of the housing 1 to ensure the stability of the placement. This makes it inconvenient to apply force to remove the LED frame 4. The spring 35 drives the sliding rod 341 to slide, thereby moving the LED frame 4 away from the corresponding positioning bar 21, so that the LED frame 4 is partially detached from the housing 1, thus making it easier to remove the LED frame 4.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
