Contamination components: solder is required when welding the light board; 5. Low production efficiency: the entire traditional photoelectric direct reading module has complex inspection process steps and low production capacity; 6.

The transmission direction of the light beam emitted by the emitting lamp 11 in the light guide module 8 is as follows: Figure 3 As shown, Figure 5 It is a schematic diagram of the integration of the light guide module and the light guide module.

[0075] Preferably, the controller includes an instruction sending component, an information collection component, a comparator and a result output component. The instruction sending component is used to send a detection instruction to the light guide module, so that the light guide module emits light according to the detection instruction.

[0080] In a specific embodiment of the present invention, the optical guide metering device detection device further includes a data transmission component and a communication interface 5.

[0088] Embodiment 2

[0089] like Figure 6 As shown, this embodiment provides a method for detecting a photoconductive metrology device, which is applied to the method for detecting a photoconductive metrology device provided in Embodiment 1. The method for detecting a photoconductive metrology device includes:

[0090] Step 100 , in the detection phase and when the light guide metering device does not receive a detection instruction, the light guide module and the light guide module are engaged to allow the light beam emitted by the light guide module to enter the light guide module.

[0091] Step 200: sending a detection instruction to the light guide module, so that the light guide module emits light according to the detection instruction.

[0092] Step 300, outputting the detection status of the light guide metering device according to the sampling result; the detection status includes qualified and unqualified; the sampling result is determined by the light guide module performing A / D sampling on the light beam returned by the light guide module.

[0093] Specifically, outputting the detection state of the photoconductive metering device according to the sampling result specifically includes:

[0094] Step 2001: Send a detection instruction to the light guide module, so that the light guide module emits light according to the detection instruction.

[0095] Step 2002, obtaining the sampling result; the type of the sampling result is a light guide module sampling result or a light guide module sampling result.

[0096] Step 2003, determine whether the sampling result is the same as the preset value, and output the comparison result; when the sampling result is the sampling result of the light guide module, the first preset value is determined according to the state of the light guide module and the supporting assembly, and when the sampling result is the sampling result of the light guide module, the second preset value is determined according to the state of the light guide module; the comparison result is the light guide module comparison result or the light guide module comparison result.

[0097] Step 2004a: when the light guide module comparison result output by the comparator is that the light guide module sampling result is the same as the first preset value, output that the detection status of the light guide module is qualified.

[0098] Step 2005a: when the light guide module comparison result output by the comparator is that the light guide module sampling result is different from the first preset value, outputting the detection status of the light guide metering device as unqualified.

[0099] Alternatively, in step 2004b, when the light guide module comparison result output by the comparator is that the light guide module sampling result is the same as the second preset value, the detection status of the light guide module is output as qualified.

[0100] Step 2005b: when the light guide module comparison result output by the comparator is that the light guide module sampling result is different from the second preset value, outputting the detection status of the light guide module as unqualified.

[0101] In a specific embodiment of the present invention, a method for detecting a photoconductive metrology device includes:

[0102] 1) Assemble the light guide metering device detection device in the first embodiment, connect the light guide module to the test controller through the communication interface 5, and connect the test controller to the host computer for communication.

[0103] 2) Detect the photoconductive module of the photoconductive metering device.

[0104] a) The light guide module is matched with the counter of the supporting assembly, and the counter is adjusted to determine a first preset value according to the current reading of the counter. The first preset value is a hexadecimal code determined according to the current reading.

[0105] b) Turn on the power, and the host computer sends the detection command through the customized protocol through the detection controller to the light guide module.

[0106] c) The main control chip (single-chip microcomputer) of the light guide module lights up the transmitting lights one by one according to the detection instructions (the transmitting lights are turned on / off by controlling the high and low levels output by the single-chip microcomputer IO port), and performs A / D sampling on the light beam returned from the light guide module 8 to obtain the sampling results of the light guide module; specifically, the analog quantity is converted into a digital quantity through a functional peripheral in the single-chip microcomputer to obtain a set of coding values.

[0107] Specifically, after the transmitting lamp is turned on, the light beam passes through the light guide module 8, and the receiving lamp receives the transmitted light and then turns on. In the detection program algorithm logic set inside the single-chip microcomputer, after A / D sampling of a beam of light returned by the light guide module 8, a value between 0 and 255 will be obtained, and this value is determined according to the level of the receiving lamp. 128 is set as the middle value in the algorithm. When the sampling result is higher than 128, it is determined to be 1 and displayed as a white background in the upper computer display window. The specific value depends on the sampling value; when the sampling result is lower than 128, it is determined to be 0 and displayed as a black background in the upper computer display window. The specific value depends on the sampling result, such as Figure 7 This is a schematic diagram displayed by the host computer. Since the light guide module 7 has five emitting lamps, the A / D sampling corresponds to five channels, that is, the final sampling result is a code composed of the sampling values ​​obtained through the five channels.

[0108] d) Determine whether the sampling result of the light guide module is consistent with the first preset value. If it is consistent, the light guide module is qualified; if it is inconsistent, the light guide module is unqualified.

[0109] Specifically, the conversion between the code and the reading is realized through Table 1. After obtaining the sampling result of the light guide module, the reading corresponding to the current sampling result of the light guide module is obtained by looking up Table 1, that is, the calculated value of the current reading of the counter; and the value obtained by directly reading the counter is the current reading of the counter. In a specific embodiment, the calculated value of the current reading of the counter can be compared with the current reading of the counter to see if they are consistent. If they are consistent, the light guide module is qualified; if they are inconsistent, the light guide module is unqualified.

[0110] For example: if the sampling value of channel 1 D1 is higher than 128, D1 is 1; if the sampling value of channel 2 D2 is lower than 128, D2 is 0; if the sampling value of channel 3 D3 is lower than 128, D3 is 0; if the sampling value of channel 4 D4 is lower than 128, D4 is 0; if the sampling value of channel 5 D5 is lower than 128, D5 is 0. D1-D5 thus form the binary 10000, which is converted to hexadecimal 0x10, that is, the code is 0x10. According to the code, look up the table (for example, Table 1) to get a value of 0-9, which represents the calculated value of the current reading of the counter. And so on, get the values ​​of all bits (tens, hundreds, thousands, etc.), which together form the complete reading. In specific applications, Table 1 can have multiple settings, which can be set according to actual conditions.

[0111] Table 1

[0112]

[0113] 3) Test the light guide module of the same light guide metering device. If the light guide module 8 cannot completely guide light, then when the transmitting lamp of the light guide module 7 transmits light, the light received by the receiving lamp will be weakened after passing through the light guide component, and the intensity of the light directly affects the conduction of the receiving lamp, or even the conduction. The receiving lamp will obtain different sampling values ​​under different conduction conditions. Therefore, it is also necessary to test the light guide module 8.

[0114] a) Remove the counter in the support assembly so that the light guide assembly is in an unobstructed state. After the transmitting lamp of the light guide module is lit, the receiving lamp should receive light and turn on, that is, the sampling results of the single-chip computer should all be less than 128, and the results of the five sampling channels are all 0. That is, the second preset value is the hexadecimal code when the receiving lamp of the light guide module completely receives the light emitted by the transmitting lamp.

[0115] b) Turn on the power, and the host computer sends the detection command through the customized protocol through the detection controller to the light guide module.

[0116] c) The main control chip (single-chip microcomputer) of the light guide module lights up the transmitting lights one by one according to the detection instructions (the transmitting lights are turned on / off by controlling the high and low levels output by the single-chip microcomputer IO port), and performs A / D sampling on the light beam returned from the light guide module 8 to obtain the sampling results of the light guide module; specifically, the analog quantity is converted into a digital quantity through a functional peripheral in the single-chip microcomputer to obtain a set of coding values.

[0117] d) Determine whether the sampling result of the light guide module is consistent with the second preset value. If it is consistent, the light guide module is qualified; if it is inconsistent, the light guide module is unqualified. Specifically, if the upper computer display window is black, the number is less than 128, and the optimal effect number is all 0, then the current light guide module 8 is determined to be qualified; if the upper computer display window is white, and the number is greater than 128, it means that the light guide module 8 cannot completely guide light, and the current light guide module 8 is determined to be defective, and the light guide module 8 needs to be replaced and the light guide metering device is tested again.

[0118] Embodiment 3

[0119] This embodiment provides a method for detecting a light guide metering device, comprising the following steps:

[0120] A) Place the bracket 10 on a flat test bench.

[0121] B) Select a light guide module 8 with good precision light guiding performance, and press the light guide module 8 into the counter to ensure that the light guide module 8 and the counter can fit completely; fix the light guide module 8 and the counter in the counter fixture; install the light guide module 7 on the module fixing fixture 6 to ensure the installation fits.
