Description

Technical Field

[0001] The utility model belongs to the technical field of light bar testing, and particularly relates to a light bar lighting test bench. Background Art

[0002] An LED light bar refers to assembling LEDs on a strip-shaped FPC (flexible printed circuit board) or a rigid PCB board. The flexible LED light bar uses an FPC as the assembly circuit board and is assembled with surface-mounted LEDs, making the thickness of the product only 0.1 cm, taking up no space, and being suitable for use in irregular places and places with narrow spaces. Existing LED light bars will undergo lighting tests during the production process. Usually, a light bead area and a test point area are provided on an LED light bar.

[0025] As Figure 1 shown, the present utility model provides a light bar lighting test bench, which includes a workbench 1, a test unit arranged side by side on the workbench 1; the test unit includes a conveyor belt 2, a positioning tooling 7 movably installed on the workbench 1, and a first positioning component 5 located outside one side of the conveyor belt 2 and installed on the workbench 1. The detection component 4 is installed at one end of the workbench 1 through a gantry 3. The second positioning component 6 is located outside one end of the conveyor belt 2 close to the detection component 4 and installed on the workbench 1. The workpiece 8 is provided with a lamp bead area 9 and a test point area 10. The workpiece 8 moves the test point area 10 to directly below the detection component 4 through the conveyor belt 2

[0026] Please refer to Figure 2 for key reference. The first positioning component 5 includes a first cylinder 501 installed on the workbench 1 through a first bracket, and a tightening plate 502 is installed on the first cylinder 501

[0027] Please refer to Figure 4 for key reference. The second positioning component 6 includes a third cylinder 601 installed on the workbench 1 through a second bracket, and a positioning plate 602 installed on the third cylinder 601

[0028] When the workpiece 8 is moved to the positioning position, the first cylinder 501 is turned on. The first cylinder 501 pushes the tightening plate 502, and the tightening plate 502 then pushes the workpiece 8 to closely adhere to the side wall of the conveyor belt 2, so as to ensure that each workpiece 8 reaching the positioning position can be aligned along the side wall of the conveyor belt 2. At the same time, the third cylinder 601 is turned on, and the third cylinder 601 pushes the positioning plate 602 to rise, so as to be able to limit the extreme position of the forward movement of the workpiece 8; the dual positioning cooperation of the first positioning component 5 and the second positioning component 6 can ensure the accuracy of the positioning position of the workpiece 8

[0029] Please refer to Figure 2 and Figure 3, the positioning tooling 7 includes a tooling plate 701, on which several ventilation holes are provided, and several fans 702 are installed on the bottom of the tooling plate 701. The tooling plate 701 is movably installed on the workbench 1 through a guide shaft 703 and a flange 704 in cooperation with a second cylinder 705.

[0030] After the workpiece is positioned, the second cylinder 705 is activated, so as to drive the workpiece 8 away from the conveyor belt 2, avoiding the subsequent influence of the conveyor belt 2 on the workpiece 8. At the same time, the fan 702 is used to dissipate the heat generated when the workpiece 8 is tested, preventing the heat from accumulating in the workpiece 8.

[0031] Please refer to Figure 5 , the detection component 4 includes a moving plate one 401 movably installed on the gantry 3 through a linear guide 402, and a fixed seat 403 installed on the gantry 3. A limit screw one 404 is threadedly installed on the fixed seat 403, and one end of the limit screw one 404 abuts against the moving plate one 401. At the same time, a mounting plate 405 is installed on the moving plate one 401. A moving plate two 407 is movably installed on the mounting plate 405 through a chute in cooperation with a slide rail 408. A limit screw two 406 is threadedly installed on the mounting plate 405, and one end of the limit screw two 406 abuts against the moving plate two 407. A fourth cylinder 409 is installed on the moving plate two 407, and a fixing plate 410 is installed on the fourth cylinder 409. Arc-shaped grooves 411 are symmetrically provided on the fixing plate 410. A rotating plate 412 is movably installed on the fixing plate 410 through a limit screw three in cooperation with the arc-shaped grooves 411. At the same time, several probes 413 are installed on the rotating plate 412.

[0032] When the workpiece 8 is ejected by the positioning tooling 7 and separated from the conveyor belt 2, the test point area 10 of the workpiece 8 is located directly below the probes 413. At this time, the fourth cylinder 409 is activated, so that under the drive of the fourth cylinder 409, the probes 413 contact the test point area 10 for electrical testing, and observe whether the lamp bead area 9 lights up. If all light up, it is a qualified workpiece; if there is a lamp bead that does not light up, it is an unqualified workpiece.

[0033] At the same time, this device can be applicable to workpieces of different specifications. In order to adapt to workpieces of different specifications, the position of the probes 413 can be changed by adjusting the limit screw one 404, the limit screw two 406 and the limit screw three, so as to contact the test point areas of workpieces of different specifications.

[0034] The conveyor belt 2, the first cylinder 501, the fan 702, the second cylinder 705, the third cylinder 601, the fourth cylinder 409 and the probes 413 are communicatively coupled to the control panel.

[0035] The control panel contains a PLC controller. The PLC controller is a programmable numerical control system. As the central control system, the PLC uses a touch screen to realize the program input and operation control of the whole machine, achieving full automation of the transportation process. The control system can be used as a system that connects each actuator to move along a logical trajectory, and controls the actuator to operate according to the required operation steps through programming.

[0036] The working principle of the present utility model is as follows:

[0037] The workpiece 8 is transported to the workbench 1 along with the conveyor belt 2. When the test point area 10 of the workpiece 8 is transported directly below the detection component 4, the first cylinder 501 and the third cylinder 601 are activated to position the workpiece 8. Subsequently, the blower 702 and the second cylinder 705 are activated, and the workpiece 8 is separated from the conveyor belt 2. Then, the fourth cylinder 409 is activated to make the probe 413 contact the test point area 10, thereby testing the workpiece 8. The lamp strip condition of the lamp bead area 9 is observed to determine whether the workpiece is a qualified workpiece. At the same time, the blower 702 dissipates heat from the workpiece 8.

[0038] This device can perform double automatic positioning on the workpiece to ensure the accuracy of the positioning position of the workpiece 8; at the same time, it realizes automatic testing of the lamp bead area 9 of the workpiece to determine whether the workpiece is a qualified workpiece; and dissipates heat from the workpiece 8 during testing.

[0039] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
