Description
Technical Field
The present invention relates to a wire detecting device and a wire detecting method.
Background
Generally, when a signal line transmits a signal, since a signal transmitting end and a signal receiving end do not have the same potential, a potential difference exists between devices at both ends to form a noise voltage. The noise voltage will be squeezed out toward the insulation layer of the signal line and directly penetrate the outer side of the insulation layer to generate the interference effect of electromagnetic mutual inductance with the signal of the surrounding circuit. This affects the quality of the overall transmission signal, i.e. the so-called Electromagnetic Interference (EMI). Therefore, how to eliminate the electromagnetic interference is the subject to be faced by the present signal line to maintain the transmission quality.
In order to reduce the electromagnetic interference of the device, a method commonly adopted at present uses a differential transmission mode. The transmission method of Low-voltage differential signaling (LVDS) has the advantage of Low power voltage requirement, so that a relatively faster and more stable signal can be generated. According to the LVDS interface standard defined by ANSI-YUA-EIA-644-I995, signal lines used in LVDS signal transmission systems must have a characteristic impedance (Z0) of 100 Ω + -5% to match the circuit impedance (Z) of the liquid crystal display interface and the system motherboard interface to reduce electromagnetic interference and noise (noise) interference. Otherwise, signal reflection and noise interference will occur in signal transmission between the lcd interface and the system board interface, and signal loss, distortion and distortion will be caused.
In addition, when the LVDS wires are managed, in order to separate the qualified LVDS wires from the unqualified LVDS wires, it is a common practice to judge whether the LVDS wires are good or bad by the integrity of the appearance of the LVDS wires, but it is proved that the LVDS wires which do not look like without problems in appearance are qualified products which can be normally used. Therefore, to ensure that the LVDS wires are qualified, a specific testing machine is required to be used to see the detection images through the panel, but many detection images are often required to be passed to determine whether the LVDS wires are qualified, which is a time-consuming, labor-consuming and cost-consuming method.

Detailed Description
In the following description, for purposes of explanation, numerous implementation details are set forth in order to provide a thorough understanding of the various embodiments of the present invention. It should be understood, however, that these implementation details are not to be interpreted as limiting the invention. That is, in some embodiments of the invention, such implementation details are not necessary. In addition, some conventional structures and components are shown in simplified schematic form in the drawings.
One aspect of the present invention is a wire detecting device. More specifically, the second testing end can be connected to one end of the wire to be tested, and one of the first end connecting portions included in the first testing end can be selectively connected to the other end of the wire to be tested, so that the functions of multi-path switching and channel-divided voltage quantity acquisition of the wire to be tested can be achieved. Then, the wire detecting device selects a corresponding data acquisition function through selection of the selection key, the processor acquires corresponding data according to one end of the wire to be tested at the first testing end and compares the corresponding data with the other end of the wire to be tested at the second testing end to generate a testing result, and the testing result is displayed on the display unit. In addition, the second testing end of the wire detecting device replaces the conventional manual wire plugging mode with the mechanism wire plugging mode, so that a single tester can easily perform the detection procedure of the wire to be detected.
Please refer to fig. 1. Fig. 1 is a perspective view of a wire detecting device 1 according to an embodiment of the invention.
As shown in fig. 1, in the present embodiment, the wire detecting device 1 can be used to test a plurality of different types of wires 2 (only one wire 2 is shown in fig. 1), and each wire 2 includes a first end 2a and a second end 2b having a plurality of pins (pins). The wire detecting device 1 can selectively electrically connect one of the wires 2. For example, the type of the wire 2 may be LI-10, LI-16, LI-17, LI-20, LT-15B …, etc., but the present invention is not limited thereto. The wire detecting device 1 of the present invention comprises a plurality of selection keys 10, a first testing terminal 12 and a second testing terminal 14. Each selection button 10 of the wire detecting device 1 corresponds to one of the wires 2. The first test end 12 of the wire detecting device 1 includes a plurality of first end connection portions 120. Each first end connecting portion 120 of the first testing end 12 is correspondingly connected to the first end 2a of the wire 2. The second testing end 14 of the wire detecting device 1 is used for connecting the second end 2b of the wire 2. Further, the first end connecting portion 120 of the first testing end 12 includes a board 120a, and the board 120a has a plurality of pins 120a 1. The first end 2a of the wire 2 has a slot (not shown) and a plurality of pins (not shown) are provided in the slot. The pins in the slots are electrically connected with the wires 2. After the board 120a of the first end connection portion 120 is inserted into the slot of the first end 2a and the pin 120a1 of the board 120a is electrically connected to the pin in the slot, the first end 2a of the wire 2 is electrically connected to the first end connection portion 120. However, the manner of electrically connecting the first end 2a of the wire 2 and the first end connecting portion 120 is not limited to this embodiment.
In other words, when one type of the wire 2 is connected to the wire detecting device 1 of the present invention, the first end 2a of the wire 2 is connected to the first end connecting portion 120 of the first testing end 12 corresponding to the type, and the second end 2b of the wire 2 is connected to the second testing end 14, so that the wire 2 can be completely connected to the wire detecting device 1 of the present invention.
The first testing end 12 shown in fig. 1 only includes four first end connecting portions 120, but the invention is not limited thereto, and the number of the first end connecting portions can be flexibly increased or decreased according to the number of the wire types to be detected.
Please refer to fig. 2. Fig. 2 is a functional block diagram of the wire detecting device 1 in fig. 1.
As shown in fig. 2, in the present embodiment, the wire detecting device 1 further includes a processor 16, a key circuit 160, a signal collecting circuit 162 and a display unit 18. The processor 16 is electrically connected with the key circuit 160, the key circuit 160 is electrically connected with the selection key 10, and the processor scans the key circuit for the touch condition of the key through a plurality of key scanning functions. Each key scan function corresponds to one of the selection keys 10. The processor 16 performs signal data acquisition via the signal acquisition circuitry 162 through a plurality of data acquisition functions. The data acquisition function corresponds to one of the selection keys 10. When the first end 2a and the second end 2b of the wire 2 are electrically connected to the wire detecting device 1 and the selection key 10 corresponding to the electrically connected wire 2 is touched, the processor 16 of the wire detecting device 1 scans according to the key scanning function via the key circuit 160 to determine the touched selection key 10. The processor 16 of the wire detecting device 1 performs data acquisition on the electrically connected wires 2 through the signal acquisition circuit 162 according to the data acquisition function corresponding to the touched selection key 10, so as to generate a test result.
In other words, when one type of the wire 2 is to be detected, the selection key 10 corresponding to the wire 2 is first touched after the first end 2a and the second end 2b of the wire 2 are respectively connected to the first testing end 12 and the second testing end 14 of the wire detecting device 1. The processor 16 of the wire detecting device 1 scans all the selection keys 10 at any time according to the key scanning function via the key circuit 160, so that after the key circuit 160 scans and matches the key scanning function corresponding to the selection key 10, the selection key 10 can be determined (that is, the wire detecting device 1 can determine what the touched selection key 10 is), and if the wire 2 does not match the touched selection key 10, the selection key 10 is reselected until matching. Then, the processor 16 of the wire detecting device 1 performs data acquisition on the wire 2 through the signal acquisition circuit 162 according to the data acquisition function corresponding to the touched selection key 10, so as to generate a test result. The data acquisition function includes all items to be detected of the wire 2, so that after the processor 16 performs data acquisition on the wire 2 through the signal acquisition circuit 162, the data and results of all the detected items of the wire 2 are displayed on the screen of the display unit 18. Therefore, compared with the conventional method that whether the wire to be tested is qualified or not can be known by measuring a plurality of pictures through the conventional wire testing machine and manually analyzing the pictures, the wire testing device 1 of the present invention can directly display the testing result through the display unit 18, thereby greatly reducing the testing time and reducing the misjudgment rate.
For example, when a wire is inspected by using a conventional inspection machine, it takes one to two minutes to inspect a single wire because many frames are observed manually and the inspection results displayed on the frames are observed. In contrast, after the wire detecting device 1 of the present invention touches the selection button 10 corresponding to the wire 2, the signal collecting circuit 162 collects data of the wire 2 and displays the type and result of the detected wire on the screen of the display unit 18, so that it only takes several seconds to detect one wire 2, and human analysis factors are eliminated, thereby reducing the probability of erroneous judgment and obtaining more accurate measurement result.
Please refer to fig. 3A and fig. 3B. Fig. 3A is a partial top view of the wire detecting device 1 in fig. 1, wherein the second end connecting portion 140 has not moved toward the limiting member 142. Fig. 3B is a partial top view of the wire detecting device 1 in fig. 1, wherein the second end connecting portion 140 is already in contact with the limiting member 142.
As shown in fig. 1, fig. 3A and fig. 3B, in the present embodiment, the second testing end 14 of the wire detecting device 1 includes a second end connecting portion 140 and a limiting member 142. The second end connecting portion 140 of the second testing end 14 is disposed on the wire detecting device 1 and can slide along the first direction a1 relative to the wire detecting device 1. The limiting member 142 of the second testing end 14 is used for fixing the second end 2b of the wire 2 in a pluggable manner. The second end-connecting portion 140 of the second testing end 14 can move toward the limiting member 142 along the first direction a1, so that the second end 2b of the wire 2 is electrically connected to the second end-connecting portion 140. Further, the second end connecting portion 140 of the second testing end 14 includes a board 140a, and the board 140a has a plurality of pins 140a 1. The limiting member 142 of the second testing end 14 has a slot (not shown, located on the other side of the limiting member 142 in fig. 1 opposite to the second end 2b of the wire 2), and the slot has a plurality of pins (not shown). The pin in the slot is electrically connected to the second end 2b of the wire 2. When the second end connecting portion 140 of the second testing end 14 moves toward the position-limiting member 142 along the first direction a1, the inserting plate 140a of the second end connecting portion 140 is inserted into the slot of the position-limiting member 142, and the pin 140a1 of the inserting plate 140a is electrically connected to the pin in the slot, so as to electrically connect the second end 2b of the wire 2 to the second end connecting portion 140. However, the manner of electrically connecting the second end 2b of the wire 2 and the second end connecting portion 140 is not limited to this embodiment.
Moreover, the second testing end 14 of the wire detecting device 1 further includes a rack 144 and an actuating component 146, the rack 144 of the second testing end 14 is disposed on the housing 1a of the wire detecting device 1 along the first direction a1, the actuating component 146 of the second testing end 14 includes a gear 146a and a handle 146b, and the gear 146a of the actuating component 146 engages the rack 144 and is coupled to the second end connecting portion 140. The handle 146b of the actuator 146 is connected to the gear 146a for rotating relative to the rack 144 to roll the gear 146a relative to the rack 144, so as to drive the second end connecting portion 140 to move along the first direction a1 relative to the wire detecting device 1.
Also shown in fig. 1, 3A and 3B, the wire detecting device 1 further includes a first rail (not shown) located below the second testing end 14, a second rail 1B, two clamping members 148 and two clamping arms 150. The first rail of the wire detecting device 1 is disposed on the housing 1a of the wire detecting device 1 in the first direction a1, the second end connecting part 140 of the second testing end 14 moves along the first rail, and the second rail 1b of the wire detecting device 1 is disposed on the housing 1a of the wire detecting device 1 in the second direction a 2. The limiting member 142 of the second testing end 14 is disposed in the second rail 1b (i.e., the limiting member 142 of the second testing end 14 is a component disposed on the second rail). The two clamping members 148 of the wire detecting device 1 are located in the second track 1b and located at two sides of the limiting member 142 respectively. The two holding pieces 148 of the wire detecting device 1 are slidable only in the second direction a2 in the second rail 1 b. The two clamping arms 150 of the wire detecting device 1 are respectively disposed at two sides of the second end connecting portion 140 and extend toward the limiting member 142. The retaining member 142 and the retaining member 148 of the second testing end 14 are located between the retaining arms 150. When the second end connecting portion 140 has not moved along the first track (i.e., the first direction a1) toward the position-limiting member 142, the two clamping arms 150 of the wire detecting device 1 respectively contact the two clamping members 148, but the two clamping members 148 do not contact the position-limiting member 142, as shown in fig. 3A. However, during the movement of the second end connecting portion 140 toward the position-limiting member 142 along the first track, each clamping arm 150 makes the corresponding clamping member 148 approach toward the position-limiting member 142 along the second track 1B, so that the second end 2B of the wire 2 is clamped between the clamping members 148, as shown in fig. 3B.
Further, each of the clamping arms 150 of the wire detecting device 1 includes a first clamping portion 150a and a guiding portion 150 b. The first clamping portion 150a of the clamping arm 150 is connected to the second end connecting portion 140. The guiding portion 150b of the clamping arm 150 is connected to the first clamping portion 150a for guiding the corresponding clamping member 148 to slide along the second track 1b toward the limiting member 142 during the movement of the second end connecting portion 140 along the first track toward the limiting member 142. In addition, each of the clamp arms 150 of the wire detecting device 1 further includes a second clamp portion 150 c. The second clamping portion 150c of the clamping arm 150 is connected to the corresponding guide portion 150b and is substantially parallel to the first clamping portion 150 a. When the second end connecting portion 140 has not moved along the first track (i.e., the first direction a1) toward the limiting member 142, the second clamping portion 150c of each clamping arm 150 contacts with the two clamping members 148, respectively, as shown in fig. 3A. However, each clamping arm 150 of the wire detecting device 1 may not include the second clamping portion 150c, if only for the purpose of guiding the corresponding clamping member 148 to slide along the second track 1b toward the limiting member 142 during the movement of the second end connecting portion 140 along the first track toward the limiting member 142.
It should be noted that the distance between the two first clamping portions 150a of the two clamping arms 150 in the second direction a2 is slightly smaller than the sum of the length of the limiting member 142 of the second testing end 14 in the second direction a2 and the length of the two clamping members 148 in the second direction a2, so that when the second end connecting portion 140 moves along the first track toward the limiting member 142 to make each first clamping portion 150a contact with the corresponding clamping member 148, each clamping arm 150 can firmly make the corresponding clamping member 148 clamp the limiting member 142 (i.e., similar to the tight fit concept).
Therefore, the wire detecting device 1 of the present invention can stably fix the limiting member 142 while the second end connecting portion 140 moves toward the limiting member 142 along the first track, so that the second end 2b of the wire 2 is connected to the second end connecting portion 140 with better stability. Moreover, the second testing end 14 of the wire detecting device 1 replaces the conventional manual wire plugging method by the above-mentioned mechanical wire plugging method, so that a single tester can easily connect the second end 2b of the wire 2 with the second end connecting portion 140 by simply rotating the handle 146b of the actuating member 146, thereby performing the detecting procedure of the wire 2 through the wire detecting device 1 of the present invention.
In another embodiment, the wire detecting device 1 of the present invention can arrange the selection button 10 at the end of the second clamping portion 150c of the clamping arm 150 in fig. 3B, so that the wire detecting device 1 of the present invention can achieve the purpose of automatic measurement. After the second end connecting portion 140 moves toward the limiting member along the first direction a1, and when the second end connecting portion 140 is inserted into the second end 2b of the wire 2, the second clamping portion 150c of the clamping arm 150 will contact the selection button 10, so that the wire detecting device 1 of the present invention will automatically call the corresponding function to measure the wire 2 and give the test result. The advantage of this embodiment is that one manual operation is omitted, thereby saving more detection time.
In one embodiment, the wire detecting device 1 of the present invention further includes an electrical storage device (not shown). The electrical storage device of the wire detecting device 1 is electrically connected to the processor 16 for supplying power to the wire detecting device.
The wire 2 detected by the present invention is a Low-voltage differential signaling (LVDS) wire, but the present invention is not limited thereto.
Please refer to fig. 4. Fig. 4 is a flowchart illustrating steps of a wire detecting method according to an embodiment of the invention.
As shown in fig. 4, in the present embodiment, a wire detecting device is used to detect a plurality of different types of wires. The wire detection device comprises a plurality of selection keys and a display unit. Each selection button of the wire detection device corresponds to one of the wires. As for the components included in the wire detecting device and the connection relationship between the components, reference may be made to the wire detecting device 1 shown in fig. 1 and fig. 2 and the related description thereof, which are not repeated herein.
It is to be noted herein that the wire rod detection method of the present invention includes the following steps.
Step S100: the wire is electrically connected to the wire detecting device.
Step S102: and scanning and selecting the keys according to the plurality of key scanning functions to further obtain a scanning result.
Step S104: and judging whether the selection key corresponding to the electrically connected wire is touched according to the scanning result.
If the determination result in step S104 is yes, step S106 is further performed. If the determination result in step S104 is negative, step S102 is repeatedly executed.
Step S106: and carrying out data acquisition on the electrically connected wires according to the data acquisition function corresponding to the touched selection key so as to generate a test result.
Step S108: and displaying the test result on the display unit.
As can be clearly seen from the above detailed description of the specific embodiments of the present invention, in the wire detecting device of the present invention, the second testing end of the wire detecting device can be connected to one end of the wire to be tested, and one of the first end connecting portions included in the first testing end of the wire detecting device can be selectively connected to the other end of the wire to be tested, so that the functions of multi-path switching and channel-by-channel voltage acquisition of the wire to be tested can be achieved. And then, the wire rod detection device selects a corresponding data acquisition function through selection of the selection key, the processor acquires corresponding data according to one end of the wire rod to be tested at the first test end, and performs data comparison with the other end of the wire rod to be tested at the second test end, so as to generate a test result, and the test result is displayed on the display unit. The pin result of the wire to be tested can be displayed through the corresponding keys. Therefore, compared with the mode that whether the wire to be tested is qualified or not can be known only by measuring a plurality of pictures and manually analyzing by the conventional wire testing machine, the wire testing device greatly reduces the testing time and reduces the misjudgment of the testing result. In addition, the second testing end of the wire detecting device replaces the conventional manual wire plugging mode with the mechanism wire plugging mode, so that a single tester can easily perform the detection procedure of the wire to be detected.
