Description

Technical Field

[0001] This invention relates to the field of wire testing technology, and in particular to a lightweight wire detector. Background Technology

[0002] Flat wires are widely used in electronic devices, automotive wiring harnesses, and other fields. Their mechanical properties directly affect the safety and reliability of end products. Therefore, tensile strength testing is a core aspect of flat wire production and quality control. Current tensile strength testing technology in the industry primarily involves applying tensile force to the entire flat wire using tensile testing equipment to determine whether the wire has reached a preset tensile strength threshold. However, existing tensile testing equipment has the following shortcomings: On the one hand, due to the lack of an independent monitoring mechanism for multiple wires inside flat wires, it is impossible to obtain the breaking sequence and real-time stress change data of each individual wire during the testing process. It can only achieve basic testing and evaluation of the overall fracture of the wire, which makes it impossible to accurately analyze the root cause of wire failure and thus difficult to optimize product structure and production process in a targeted manner. On the other hand, the existing testing method is not continuous. After each wire is tested, it is necessary to manually reposition, cut and clamp new wires, which is cumbersome, labor-intensive and has low testing efficiency. Summary of the Invention

[0003] To overcome the shortcomings of traditional flat wire breakage testing, which only reveals the overall breakage of the flat wire and cannot determine the breakage sequence and stress of individual wires within it, and which lacks continuous testing capability and requires time-consuming and labor-intensive reassembly of the flat wire after each test, this invention provides a lightweight wire detector. The detector includes a mounting platform, a first clamp, a first slide, and a second clamp. The first clamp is fixedly mounted on the left side of the mounting platform; the first slide is mounted on the right side of the mounting platform; the second clamp is mounted on the first slider of the first slide; and the detector also includes a first connecting plate and a first… The system comprises an electric push rod, a first energized pin, a second connecting plate, a second electric push rod, and a second energized pin. A first connecting plate is fixed to the left side of the mounting platform. A first electric push rod is mounted on the top of the first connecting plate. A first energized pin is mounted on the telescopic part of the first electric push rod. A second connecting plate is fixed to the first slider. A second electric push rod is mounted on the top of the second connecting plate. A second energized pin is mounted on the telescopic part of the second electric push rod. The first and second energized pins are electrically connected. By inserting the pins of the first and second energized pins into the wires of the flat wire, the breakage status of each wire in the flat wire is detected.

[0004] Furthermore, both the first and second power-on connectors are equipped with multiple pins, the number of which is the same as the number of wires in the flat cable.

[0005] Furthermore, it also includes a third clamp, a second slide, and a fourth clamp; the third clamp is mounted on the first slide; the second slide is mounted on the front side of the mounting platform; and the fourth clamp is mounted on the second slide of the second slide.

[0006] Furthermore, the clamping parts of the first clamp and the fourth clamp face opposite directions; it also includes an L-shaped conveying clamp; each of the two clamping parts of the fourth clamp is fixedly connected to an L-shaped conveying clamp on its left side, and elastic pads are provided on the opposing sides of the L-shaped conveying clamps.

[0007] Furthermore, it also includes a cutter; the cutter is mounted on the left side of the first energized pin.

[0008] Furthermore, the bottom height of the cutter is higher than the bottom height of the first energized pin.

[0009] Furthermore, it also includes a fixing ring, an elastic element, a connecting plug, and a guide; a fixing ring is fixedly connected to the left side of the mounting platform; an elastic element is fixedly connected to the inside of the fixing ring; a connecting plug is fixedly connected to the end of the elastic element; the connecting plug and the guide are detachably connected; the guide has a guide hole adapted to the shape of the flat wire.

[0010] Furthermore, an inflatable airbag is installed in the guide hole of the guide.

[0011] Furthermore, a limit groove is provided on the right side of the guide, and a limit stop bar that fits the limit groove is fixedly connected to the right side of the fixing ring.

[0012] Furthermore, it also includes a wiping block, which is detachably connected to the left end of the guide.

[0013] Compared with existing technologies, the present invention has the following advantages: Addressing the core problem of existing equipment that can only detect overall wire breakage and cannot obtain the status of individual wires, the present invention uses a first and a second energized pin to insert one pin at each end of a single wire in a flat wire. After energization, the current flow can be used to identify whether a single wire is broken in real time. Combined with a force sensor on the first slider, it synchronously records the real-time force data when each wire breaks, providing direct data support for wire failure analysis. The equipment is lightweight and can be placed on a workbench.

[0014] This invention addresses the cumbersome problem of existing testing methods requiring repeated manual positioning, cutting, and clamping. By using an L-shaped conveyor clamp, a cutter, and a second slide, the invention achieves continuous testing by automatically cutting off the tested section and pulling out the pin after testing is completed. The fourth clamp is not fully open, and the remaining wire is elastically released by the elastic pad and moved to the right to the testing position. Subsequently, the clamp automatically resets and clamps, enabling continuous testing.

[0015] This invention addresses the issues of uneven feeding and detection deviations caused by twisting and bending of flat wires. The guide hole of the present invention is adapted to the shape of the wire, which can directionally correct the twisting and bending problems of the wire. When the flat wire is dragged to the right, the inflatable airbag in the guide hole clamps the wire, and with the help of the limiting strip and limiting groove, it can pull the wire to a horizontal and straight state, ensuring that the initial state of each section of the wire being tested is uniform and improving data consistency. At the same time, the presence of the elastic element allows the guide to move within a small range, avoiding wire jamming, damage, or wear of equipment parts caused by rigid guidance.

Detailed Implementation

[0018] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0019] Example 1: As Figures 1-6 As shown, a lightweight wire detector includes a mounting platform 1, a first clamp 2, a first slide 3, and a second clamp 4. The first clamp 2 is fixedly connected to the left side of the mounting platform 1. The first slide 3 is installed on the right side of the mounting platform 1. The second clamp 4 is installed on the first slider 3a of the first slide 3. The two ends of the flat wire are clamped and fixed by the first clamp 2 and the second clamp 4 for pull-off detection. It also includes a first connecting plate 5, a first electric push rod 6, a first energized pin 7, a second connecting plate 8, a second electric push rod 9, and a second energized pin 10; the first connecting plate 5 is fixedly connected to the left side of the mounting platform 1, wherein the first connecting plate 5 is located to the left side of the first clamp 2; the first electric push rod 6 is installed on the top of the first connecting plate 5; the first energized pin 7 is installed on the telescopic part of the first electric push rod 6; the second connecting plate 8 is fixedly connected to the first slider 3a, wherein the second connecting plate 8 is located to the right side of the second clamp 4; the second electric push rod 9 is installed on the top of the second connecting plate 8; the second energized pin 10 is installed on the telescopic part of the second electric push rod 9; the first energized pin 7 and the second energized pin 10 are electrically connected, and the breakage status of each wire in the flat wire is detected by inserting the pins of the first energized pin 7 and the second energized pin 10 into the wires of the flat wire. Both the first power-on pin connector 7 and the second power-on pin connector 10 are equipped with multiple pins. The number of pins is the same as the number of wires in the flat cable. By inserting the pins into the wires, two pins inserted into the same wire are electrically connected. By identifying the current flow, it can be determined whether the wire has been broken.

[0020] Furthermore, such as Figure 4 , Figure 5 As shown, it also includes a third clamp 101, a second slide 102, and a fourth clamp 103; the third clamp 101 is installed on the first slide 3a, and the third clamp 101 is located to the right of the second energized pin 10; the second slide 102 is installed on the front side of the mounting platform 1; the fourth clamp 103 is installed on the second slide 102a of the second slide 102; the left side of the flat wire detection section is double-clamped by the first clamp 2 and the fourth clamp 103; the right side of the flat wire detection section is double-clamped by the second clamp 4 and the third clamp 101, thus achieving a better clamping and fixing effect.

[0021] like Figure 5 As shown, the clamping parts of the first clamp 2 and the fourth clamp 103 face opposite directions, with the clamping part of the first clamp 2 facing forward and the clamping part of the fourth clamp 103 facing backward; it also includes an L-shaped conveying clamp 104; each of the two clamping parts of the fourth clamp 103 is fixedly connected to an L-shaped conveying clamp 104 on its left side, and an elastic pad 104a is provided on the opposite side of the L-shaped conveying clamp 104.

[0022] It also includes a cutter 105; the cutter 105 is installed on the left side of the first energized pin connector 7. The bottom height of the cutter 105 is higher than the bottom height of the pin of the first energized pin connector 7. When the first electric push rod 6 pushes the first energized pin connector 7 and the cutter 105 down, the pin of the first energized pin connector 7 contacts the flat wire 100 first, and then the cutter 105 contacts the flat wire 100.

[0023] To overcome the shortcomings of flat wire breakage testing, which only shows the overall breakage of the flat wire and cannot reveal the breakage sequence and stress of each wire in the flat wire, and also because breakage testing cannot be continuous and requires workers to re-clamp the flat wire after each breakage test, which is time-consuming and labor-intensive, this invention is proposed. When using, such as Figure 2 , Figure 3 , Figure 4 As shown, the flat wire 100 is clamped in the first clamp 2 and the fourth clamp 103, the second clamp 4 and the third clamp 101. The first clamp 2 and the fourth clamp 103, the second clamp 4 and the third clamp 101 respectively clamp and fix the two ends of the flat wire to be tested. Then, the telescopic part of the first electric push rod 6 is controlled to push the first energized pin 7 down, so that the pin of the first energized pin 7 is inserted into the wire of the flat wire. At the same time, the second electric push rod 9 pushes the second energized pin 10 down, so that the pin of the second energized pin 10 is inserted into the wire of the flat wire. Every two pins are inserted into one wire. At the same time, the first energized pin 7 and the second energized pin 10 are electrically connected to conduct electricity, so that the current flows in the wire. Subsequently, the first slider 3a is controlled to slide to the right on the first slide table 3, which drives the second clamp 4 and the third clamp 101 to move to the right, pulling the flat wire. As the first slide table 3 moves to the right, the wires in the flat wire are broken one by one. When the wire is broken, the current disappears. The information of the current disappearance and the tensile force are recorded in real time (for example, the tensile force information can be obtained by setting a force sensor on the first slider 3a). It can be seen that the present invention, by energizing each wire in the test section of the flat wire during the overall tensile test of the flat wire, and obtaining the fracture information based on the information of the current disappearance, can realize the detection of the breaking sequence and real-time force change data of each individual wire in the flat wire.

[0024] Furthermore, after a certain section of the flat wire has been inspected, such as Figure 4 , Figure 5 As shown, the first electric push rod 6 can be controlled to push the first energized pin 7 (cutter 105) further down, so that the cutter 105 contacts the flat wire and cuts it. Then, the first electric push rod 6 can be controlled to push the first energized pin 7 and cutter 105 to move completely upward, and the second electric push rod 9 can push the second energized pin 10 to move completely upward, so that the pin is pulled out from the wire of the flat wire. Subsequently, the clamping parts of the first clamp 2, the second clamp 4, and the third clamp 101 are fully opened, while the fourth clamp 103 is not fully opened, thus releasing the clamping and fixing of the flat wire. The not fully opened fourth clamp 103 allows the left end of the flat wire (the flat wire located in the area to the left of the cutter 105) to still be clamped by the elastically released elastic pad 104a. Then, the worker removes the tested section of the flat wire (the flat wire located in the area to the right of the cutter 105) from the released first clamp 2, the second clamp 4, the third clamp 101, and the fourth clamp 103. Then, the second slider 102a is controlled to move to the right on the second slide table 102. The second slider 102a drives the fourth clamp 103 and the L-shaped conveyor clamp 104 to move to the right. In this way, the clamped flat wire is dragged to the right by the elastic pad 104a until the new detection section of the flat wire is moved to the right side of the third clamp 101. Then, the clamping parts of the first clamp 2, the second clamp 4 and the third clamp 101 are controlled to clamp the flat wire again for the next section of flat wire breakage detection. Then, the clamping part of the fourth clamp 103 is controlled to fully open, the elastic pad 104a of the L-shaped conveyor clamp 104 no longer clamps the flat wire, and the second slider 102a is controlled to drive the fourth clamp 103 and the L-shaped conveyor clamp 104 to move to the left to reset. Then, the fourth clamp 103 is controlled to clamp the flat wire. In this way, the present invention realizes the continuous feeding of flat wire without the need for workers to reposition, cut and clamp new flat wire.

[0025] It should be noted that during the process of the elastic pad 104a of the L-shaped conveyor clamp 104 dragging the flat wire to the right, the clamping parts of the first clamp 2, the second clamp 4 and the third clamp 101 are fully opened, and the telescopic parts of the first electric push rod 6 and the second electric push rod 9 are fully moved upward, leaving room for the L-shaped conveyor clamp 104 to move and achieve avoidance.

[0026] Furthermore, such as Figure 1 , Figure 6 As shown, it also includes a fixing ring 201, an elastic element 202, a connecting block 203, and a guide 204; the fixing ring 201 is fixedly connected to the left side of the mounting platform 1; the elastic element 202 is fixedly connected to the inner side of the fixing ring 201; the connecting block 203 is fixedly connected to the end of the elastic element 202; the connecting block 203 is detachably connected to the guide 204; the guide 204 has a guide hole adapted to the shape of the flat wire 100. An inflatable airbag is provided in the guide hole of the guide 204, and the flat wire is clamped and fixed by controlling the expansion of the inflatable airbag.

[0027] A limiting groove 204a is provided on the right side of the guide 204, and a limiting stop bar 205 that fits into the limiting groove 204a is fixedly connected to the right side of the fixing ring 201.

[0028] like Figure 1As shown, it also includes a wiping block 206. The left end of the guide 204 is detachably connected to the wiping block 206 for wiping the flat cable 100. The wiping block 206 removes dirt from the surface of the flat cable.

[0029] Furthermore, when the flat wire is dragged to the right by the elastic pad 104a of the L-shaped conveyor clamp 104, the flat wire's rightward movement is uneven due to twisting and bending, and it may even pop out of the clamp. To address this, as follows... Figure 6 As shown, by passing the flat wire 100 through the guide 204 to the right, the flat wire is guided by the guide 204, which overcomes the problem of flat wire twisting and bending. At the same time, considering that the flat wire cannot be rigidly handled when twisted, an elastic element 202 (spring) is set so that the guide 204 can move within a small range when guiding the flat wire, avoiding the problem of rigidly guiding the flat wire, which may cause jamming or forced pulling that could damage the flat wire or the wire detector of the present invention. Furthermore, such as Figure 4 , Figure 6 As shown, the flat wire is dragged to the right by the elastic pad 104a of the L-shaped conveyor clamp 104. When it reaches the right side of the third clamp 101, the airbag in the guide hole of the control guide 204 is inflated to clamp the flat wire. Then, the elastic pad 104a is controlled to further drive the flat wire to the right, making the flat wire straight. At the same time, the flat wire pulls the guide 204 to the right, so that the limiting groove 204a is locked on the limiting stop 205, and the guide 204 is placed on the center line of the fixing ring 201. This makes the flat wire in the wire detector horizontal and straight. Then, when the clamping parts of the first clamp 2, the second clamp 4, the third clamp 101 and the fourth clamp 103 are subsequently controlled to clamp the flat wire, they clamp a horizontal and straight section of flat wire, which can realize the automatic straightening and correction of the flat wire and ensure the accuracy of flat wire breakage detection.
