DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The following will elaborate on the preferred embodiments of the present utility model in conjunction with the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art. It should be noted here that the description of these embodiments is used to help understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0031] Referring Figures 1 to 4 As shown, this embodiment provides a detection device for a vehicle-mounted speaker, including a bottom plate 1, detection pins 2, photoelectric sensors 3, auxiliary positioning blocks 4, a barcode scanner 6, a controller 7, a defective indicator 8, and a start button 9, wherein the number of detection pins 2 and photoelectric sensors 3 is multiple.

[0032] Furthermore, multiple detection pins 2 are arranged on the bottom plate 1 and configured to correspond one-to-one to the standard positions of multiple mounting holes 101 on the to-be-detected vehicle-mounted speaker 100. Specifically in this embodiment, the number of both the detection pins 2 and the mounting holes 101 is 4. Multiple photoelectric sensors 3 are used to be triggered after the multiple detection pins 2 are respectively inserted into the multiple mounting holes 101 of the to-be-detected vehicle-mounted speaker 100.

[0033] Specifically in this embodiment, the photoelectric sensor 3 is specifically a reflective fiber optic sensor, and the spatial resolution of the reflective fiber optic sensor is equal to the distance between the reflective fiber optic sensor and the to-be-detected vehicle-mounted speaker 100 after the multiple detection pins 2 are respectively inserted into the multiple mounting holes 101 of the to-be-detected vehicle-mounted speaker 100. For example, when the spatial resolution of the reflective fiber optic sensor is 2 mm, when the distance between the reflective fiber optic sensor and the to-be-detected vehicle-mounted speaker is less than or equal to 2 mm, it indicates that the detection pin 2 is successfully inserted into the mounting hole 101, the opening position of the to-be-detected speaker meets the requirements, and it can be successfully installed on the vehicle; when the distance between the reflective fiber optic sensor and the to-be-detected vehicle-mounted speaker is greater than 2 mm, it indicates that the detection pin 2 fails to be successfully inserted into the mounting hole 101, the opening position of the to-be-detected speaker does not meet the requirements, and thus it cannot be successfully installed on the vehicle.

[0034] More specifically, the multiple detection pins 2 include a first detection pin 21 and a second detection pin 22, and the multiple photoelectric sensors 3 include a first photoelectric sensor 31 and a second photoelectric sensor 32. Combining Figure 1 and Figure 2 as shown, the first photoelectric sensor 31 is adjacent to and lower than the first detection pin 21, and the second photoelectric sensor 32 is adjacent to and lower than the second detection pin 22.

[0035] A column 11 extending upward is fixedly arranged on the bottom plate 1, and the detection pin 2 is arranged on the column 11. The column 11 includes a first column 111 and a second column 112. The first detection pin 21 is arranged on the first column 111, the second detection pin 22 is arranged on the second column 112, and the first column 111 is higher than the second column 112.

[0036] The first photoelectric sensor 31 is arranged on the first column 111 and is lower than the first detection pin 21, and in the vertical direction, the first photoelectric sensor 31 deviates from directly below the first detection pin 21. The number of the second detection pins 22 is multiple, and the second photoelectric sensor 32 is arranged on the bottom plate 1 and is located between the multiple second detection pins 22.

[0037] Combined Figure 1 and Figure 3 As shown, the mounting holes 101 include a first mounting hole 1011 and a second mounting hole 1012. The first detection pin 21 is inserted into the first mounting hole 1011, and the second detection pin 22 is inserted into the second mounting hole 1012.

[0038] The auxiliary positioning block 4 has a guiding inclined surface facing upward for contact and cooperation with the to-be-tested vehicle-mounted speaker 100. Further, the auxiliary positioning block 4 includes a first auxiliary positioning block 42 and a second auxiliary positioning block 43. The first auxiliary positioning block 42 and the second auxiliary positioning block 43 are arranged between the multiple detection pins 2. The first auxiliary positioning block 42 has a first guiding inclined surface 421, the second auxiliary positioning block 43 has a second guiding inclined surface 431, the first guiding inclined surface 421 and the second guiding inclined surface 431 are arranged oppositely, and a positioning space 5 for accommodating the to-be-tested vehicle-mounted speaker 100 is formed between the first auxiliary positioning block 42 and the second auxiliary positioning block 43. The first guiding inclined surface 421 and the second guiding inclined surface 431 can smoothly load the to-be-tested vehicle-mounted speaker 100 as shown in Figure 3 into the positioning space 5.

[0039] The barcode scanner 6 is used to scan the barcode on the to-be-tested vehicle-mounted speaker 100 when it is loaded. The barcode scanner 6 can quickly obtain the barcode information of the to-be-tested vehicle-mounted speaker 100 and perform real-time update with the MES system. When it is detected that the opening position of the mounting hole meets the requirements, the barcode scanner 6 starts to scan the two-dimensional code of the product label.

[0040] The controller 7 is a PLC controller. The first input end of the controller 7 is electrically connected to the multiple photoelectric sensors 3, and the first output end of the controller is electrically connected to the defective indicator light 8; the second input end of the controller 7 is electrically connected to the start button 9, and the second output end of the controller 7 is electrically connected to the multiple photoelectric sensors 3.

[0041] In use, when the first detection pin 21 is inserted into the first mounting hole 1011 of the in-vehicle speaker 100 to be tested and the second detection pin 22 is inserted into the second mounting hole 1012, and the start button 9 is pressed down, all the photoelectric sensors 3 are turned on. At this time, the defective indicator light 8 does not light up, indicating that the opening position of the in-vehicle speaker to be tested is correct, and the barcode scanner 6 can be started to scan the QR code on the product label. On the contrary, if the detection pin 2 fails to be inserted into the mounting hole 101 smoothly, that is, the mounting hole 101 does not correspond to the position of the detection pin 2, the photoelectric sensor 3 is not turned on, and the defective indicator light 8 lights up. Among them, the situation where the detection pin 2 fails to be inserted into the mounting hole 101 smoothly includes that the first detection pin 21 fails to be inserted into the first mounting hole 1011, or the second detection pin 22 fails to be inserted into the second mounting hole 1012, or the first detection pin 21 fails to be inserted into the first mounting hole 1011 and the second detection pin 22 fails to be inserted into the second mounting hole 1012. If products that fail the inspection or have not been inspected are packed in boxes, the MES system cannot print out the packing list when the boxes are full. Therefore, this testing device can play a role in preventing misjudgment and missed inspection, and is relatively convenient to use.

[0042] The detection device of this embodiment inserts the detection pin 2 into the mounting hole 101 of the in-vehicle speaker 100 to be tested, and uses the corresponding photoelectric sensor 3 to detect whether the detection pin 2 is inserted into the mounting hole 101 smoothly. If the detection pin 2 is inserted into the mounting hole 101 smoothly, the photoelectric sensor 3 is turned on, and the defective indicator light 8 does not light up; if the detection pin 2 is not inserted into the mounting hole 101, the photoelectric sensor 3 is not turned on, and the defective indicator light 8 lights up. That is, it is judged whether the detection pin 2 is inserted into the mounting hole 101 smoothly through the photoelectric sensor 3. Compared with the manual method, the detection result is more accurate and it is relatively convenient to use.
