Description

Technical Field

[0001] The present invention relates to the field of electronic material testing, and in particular to an automatic electronic material performance testing device. Background Art

[0002] As a kind of electronic material, cable is mainly used to transmit electrical energy, transfer signals and distribute power. During the production process of cable, it is necessary to test the tensile performance of the cable to evaluate the tension that the cable can withstand during overhead laying, traction and use, to prevent the cable from breaking due to external force and ensure the safety of the use of wires.

[0003] In the existing cable inspection process, the cables are usually installed manually. In order to ensure the reliability of the inspection results, multiple inspections are required. Each inspection requires manual re-installation of the cables, which is time-consuming and labor-intensive, and requires a large amount of manual labor.

[0004] In addition, the existing detection method usually involves directly stretching the wire until it breaks, thereby detecting the tensile performance of the wire. However, when the wire is actually used, it will also be affected by various external forces. For example, the surface of the wire installed in the desert area is polished by flying sand and stones for a long time, causing the surface of the wire to be worn, resulting in reduced integrity of the protective layer on the surface, thereby reducing the tensile performance of the wire. At the same time, the temperature difference between day and night in the desert area varies greatly. High temperature will accelerate the aging of the cable and weaken its structural strength, making it more susceptible to deformation and breakage under the action of external forces. Low temperature may cause the cable to become hard and brittle, reducing its tensile strength. The existing detection method can only detect the tensile performance of the wire when used in a perfect environment, but cannot detect the tensile performance of the wire after being affected by external factors in actual use, thereby failing to ensure the safety level of the wire when used in various harsh environments. Summary of the invention

[0005] In order to overcome the disadvantages of the existing cable line detection process, in which the cables are usually threaded manually with the assistance of manual labor, and in order to ensure the reliability of the detection results, multiple detections need to be carried out, and the cables need to be manually re-threaded for each detection, which is time-consuming and labor-intensive and requires a large amount of manual labor, the present invention provides an automated electronic material performance detection device.

[0037] The following are the preparation steps before the cable 100 inspection:

[0038] During the specific work, the sand and stone conveying pipe of the mobile box 4 is manually connected to the external sand and stone conveying mechanism, and a roll of cable 100 to be tested is placed on the placement rack 7, and the cable 100 is pulled out and pulled between the two electric conveying rollers 8 on the left. Then, the electric guide rail 101 is controlled to drive the slider 103 and the mobile box 4, as well as other connected parts to move to the left, so that the through hole on the left side of the mobile box 4 contacts the hole of the left fixed plate 2, and the electric guide rail 101 is controlled to drive the moving block 102 and the fixed plate 2 on the right to move to the left, so that the right fixed The hole of the plate 2 contacts with the through hole on the right side of the moving box 4, and at the same time, the electric slide rail 201 is controlled to drive the sliding plate 202, the cylinder 203 and the mounting frame 5, as well as other connected parts to move to the left, so that the mounting frame 5 contacts with the through hole on the left side of the moving box 4, and the cylinder 203 is controlled to drive the mounting frame 5 and the pressing wheel 6 to move downward, so that the gap between the pressing wheel 6 and the clamp 5a is aligned with the through hole on the left side of the moving box 4, and then the electric conveying roller 8 on the left side is controlled to rotate, driving the cable 100 to pass through the hole of the left fixed plate 2 and the left side of the moving box 4 from left to right in sequence. The cable 100 is moved to the right through the gap between the pressing wheel 6 and the clamp 5a, and then the monitoring camera arranged in the cover 4a detects the length of the cable 100 conveyed. When the distance between the end of the cable 100 and the pressing wheel 6 and the clamp 5a is enough to pass through the through hole on the right side of the moving box 4 and the hole on the right side of the fixing plate 2, the electric telescopic rod on the mounting frame 5 is controlled to drive the clamp 5a to move upward, and cooperate with the pressing wheel 6 to The cable 100 is clamped, and then the electric slide rail 201 is controlled to drive the sliding plate 202 and the pressing wheel 6 to move to the right, and cooperate with the conveying of the left electric conveying roller 8, so that the cable 100 passes through the through hole on the right side of the moving box 4 and the hole of the right fixed plate 2 and contacts the right electric conveying roller 8, and then the electric telescopic rod on the mounting frame 5 is controlled to drive the clamp 5a to reset, release the clamping of the cable 100, and then the two electric conveying rollers 8 rotate relative to each other to convey the cable 100, completing the automatic threading of the cable 100 without manual work, thereby reducing the workload of manual labor.

[0039] The following are the steps for testing the tensile properties of cable 100 in perfect conditions:

[0040] When the cable 100 is automatically threaded, the electric conveying roller 8 is controlled to stop running, and then the electric slide rail 201 is controlled to drive the mounting frame 5 and the pressing wheel 6 to move to the left again, so that the mounting frame 5 and the pressing wheel 6 move to contact the left wall of the moving box 4 and return to the initial position, and then the electric clamping plate 3 in the fixed plate 2 is controlled to work to fix the cable 100, and then the electric guide rail 101 is controlled to drive the right moving block 102 and the fixed plate 2 to move to the right, stretching the fixed cable 100, and detecting the stretching force through the tension sensor on the fixed plate 2. When the cable 100 is stretched and broken, the tensile performance of the cable 100 used in a perfect environment is obtained; and in order to ensure the reliability of the data, it is necessary to carry out Multiple inspections are performed, and after each inspection is completed, the cable 100 needs to be manually re-threaded and the broken cable 100 needs to be taken out. The operation is cumbersome, the required manpower is high, and the overall inspection efficiency is low. It is explained here that after one inspection, since the fixed plate 2 on the left is in contact with the moving box 4, and the mounting frame 5 and the pressing wheel 6 are located on the left side of the moving box 4, when the cable 100 is broken, the breaking point is located inside the moving box 4 or between the moving box 4 and the right fixed plate 2, and the broken cable 100 is under the action of rebound, and the left end of the broken cable 100 will be located inside the moving box 4. Therefore, the left end of the broken cable 100 is still between the pressing wheel 6 and the clamp 5a, and then the electric clamp 3 is controlled to release. The broken end of the cable 100 is in a hanging state in the moving box 4, and the electric conveying roller 8 on the left is directly controlled to convey the cable 100, which cannot pass through the through hole on the right side of the moving box 4; therefore, the broken end of the cable 100 is first captured by the monitoring camera arranged in the cover 4a, and then the electric slide rail 201 is controlled to drive the mounting frame 5 and the pressing wheel 6 to move to the right. When the pressing wheel 6 and the clamp 5a move to the vicinity of the broken end of the cable 100, the clamp 5a is controlled to move upward, and cooperate with the pressing wheel 6 to clamp and fix the broken end of the cable 100, and the broken end of the cable 100 is The broken end of the cable 100 is kept straight under the clamping support of the pressing wheel 6 and the clamp 5a, and then the electric guide rail 101 is controlled to drive the moving block 102 and the fixed plate 2 on the right to move to the left and reset, so that the hole of the right fixed plate 2 contacts the through hole on the right side of the moving box 4 again, and then the electric slide rail 201 is continued to be controlled to drive the mounting frame 5 and the pressing wheel 6 to move to the right, and cooperate with the conveying of the left electric conveying roller 8 to drive the broken end of the cable 100 to move to the right, pass through the through hole on the right side of the moving box 4 and the hole of the right fixed plate 2 in turn, and contact the right electric conveying roller 8 to complete the automatic threading of the cable 100 after it is broken, and then the tensile performance test of the cable 100 is carried out. Such multiple tests are carried out to ensure the reliability of the test results.

[0041] The following are the steps for testing the tensile properties of cable 100 used in desert areas:

[0042] After the tensile performance test of the cable 100 in a perfect environment is completed and the automatic threading of the cable 100 after it breaks is completed, the external sand and gravel conveying mechanism is controlled to convey the sand and gravel into the mobile box 4. While conveying, the micro motor 111 is controlled to drive the two winding wheels 112 to rotate. The two winding wheels 112 rotate to reel in and unwind the pull rope 113. When one winding wheel 112 unwinds the pull rope 113, the other winding wheel 112 reels the pull rope 113, so that the pull rope 113 drives the push plate 114 to move back and forth left and right at the bottom of the mobile box 4, and the sand and gravel conveyed to the mobile box 4 are scraped flat, so that they are evenly spread on the bottom of the mobile box 4. After a certain amount of sand and gravel is conveyed, the conveying is stopped. At this time, the sand and gravel in the mobile box 4 The thickness is lower than the through holes on the left and right sides of the moving box 4 to prevent sand and stones from falling directly out of the through holes, which increases the subsequent manual cleaning work. After the moving box 4 is filled with sand and stones, the electric slide rail 201 is controlled to drive the mounting frame 5 and the pressing wheel 6 to move to the middle of the moving box 4, and then the cylinder 203 is controlled to drive the mounting frame 5 and the pressing wheel 6 to move downward. The pressing wheel 6 drives the middle part of the cable 100 located in the moving box 4 to move downward and contact with the sand and stones. At this time, the cable 100 located in the moving box 4 is in an arc shape, and then the electric guide rail 101 is controlled to drive the fixed plate 2 on the right to move to the right, so that a certain space is left between the fixed plate 2 on the right and the moving box 4, and then the electric clamping plate 3 fixes the cable 100. Figure 1As shown, the electric guide rail 101 is then controlled to drive the slider 103 to move back and forth, and the slider 103 drives the mobile box 4 and other connected parts to move back and forth, and the mobile box 4 drives the internal sand and stone to move back and forth, and the surface of the cable 100 is rubbed and rubbed by the sand and stone in the mobile box 4 to simulate the situation that the surface of the cable 100 installed in the desert area is polished by flying sand and stone for a long time; and in the process of moving and polishing, the heating tube 9 is connected to the power supply, and the heating tube 9 is controlled to heat the inside of the mobile box 4 to simulate the high temperature environment in the desert area, so that the cable 100 is rubbed with the sand and stone with temperature to ensure the rigor of the detection. At the same time, after the heating tube 9 has worked for a period of time, the heating tube 9 is controlled to stop heating, and then the external cold air delivery mechanism is controlled to pass the cold air into the cold air pipe 10, and blown into the mobile box 4 from the air blowing pipe 11 through the breathable curtain 4b to cool down the inside of the mobile box 4, and the heating tube 9 and the air blowing pipe 11 are controlled to work in turn. The temperature in the moving box 4 changes repeatedly to simulate the temperature difference between day and night in the desert area. After the moving box 4 moves to polish the cable 100 for a period of time, the cylinder 203 is controlled to drive the mounting frame 5 and the pressing wheel 6 to move up and reset, and the cable 100 moves up and breaks away from the sand and stones in the moving box 4. Then the electric slide rail 201 is controlled to drive the mounting frame 5 and the pressing wheel 6 to move to the left and reset, and then the electric guide rail 101 is controlled to drive the fixed plate 2 on the right to move to the right to stretch the cable 100 until the cable 100 breaks and stops moving, so as to detect the tensile performance of the cable 100 installed in the desert area after being affected by external factors in actual use; and the monitoring camera mounting frame 5 and the pressing wheel 6 arranged in the cover 4a are automatically threaded to the broken cable 100 again to perform multiple tests on the cable 100 to ensure the reliability of the test results; in addition, the parts in the moving box 4 can be inspected by manually opening the cover 4a.

[0043] At the same time, when the slider 103 drives the moving box 4 to move back and forth, and the cable 100 is rubbed and rubbed, when the moving box 4 moves to the right, the cable 100 will hinder the sand and stones from moving to the right, so that during the rubbing and grinding process, the sand and stones are easy to accumulate near the through hole on the left side of the moving box 4, which makes it easier for the moving box 4 to bring the internal sand and stones out to the outside when it moves, which not only increases the subsequent cleaning intensity, but also the reduction of sand and stones will affect its grinding effect on the cable 100; therefore, when the moving box 4 moves to the right, the micro motor 111 on the right side is controlled to drive the winding wheel 112 to rotate, reel the pull rope 113 on the right side, and pull the push plate 114 to move right at the bottom of the moving box 4, and the push plate 114 pushes the sand and stones on the bottom layer to move to the right. At this time, the sand and stones on the surface move to the left under the action of the cable 100, and the sand and stones on the bottom layer are pushed to move to the right by the push plate 114, so that during the mobile grinding, the sand and stones in the moving box 4 are relatively flat as a whole, reducing the accumulation of sand and stones.

[0044] According to the above working principle, we know that the present invention has the following effects:

[0045] During the detection process, the electric conveying roller 8 is controlled to cooperate with the mounting frame 5 and the pressing wheel 6 to convey the cable 100, so as to realize the automatic conveying and threading of the cable 100 and convey the broken cable 100 away, thereby realizing the automation of the overall detection, and greatly improving the detection efficiency of the tensile performance of the cable 100; and, when conveying the cable 100, the end of the broken cable 100 is supported by driving the mounting frame 5 and the pressing wheel 6 to move, so as to ensure that it can stably pass through the through hole of the movable box 4 and the hole of the fixed plate 2 during the threading process, thereby ensuring the normal progress of the detection.

[0046] Before the tensile test, the sand and stones inside the mobile box 4 are driven to move back and forth, and the sand and stones inside the mobile box 4 rub the surface of the cable 100 to simulate the situation where the surface of the cable 100 installed in the desert area is polished by flying sand and stones for a long time. By controlling the heating tube 9 and the blowing tube 11 to work in turn, the temperature in the mobile box 4 changes repeatedly to simulate the temperature difference between day and night in the desert area, so as to detect the tensile performance of the cable 100 after being installed in the desert area and being subjected to sand and stone splashing and temperature changes in actual use, thereby ensuring the safety level of the cable 100 in various harsh environments and improving the safety of the cable 100.

[0047] When filling sand and gravel, the push plate 114 is moved back and forth left and right at the bottom of the mobile box 4 to scrape the sand and gravel transported into the mobile box 4 flat and evenly spread on the bottom of the mobile box 4. When the mobile box 4 is moved for grinding, the push plate 114 is moved left and right at the bottom of the mobile box 4 to push the sand and gravel on the bottom layer of the mobile box 4 to move, so that during the moving grinding, the sand and gravel in the mobile box 4 are relatively flat as a whole, reducing the accumulation of sand and gravel. Example 2

[0048] On the basis of Example 1, Figure 5 As shown, a ring 211 is also included; the moving box 4 is fixedly connected to two rings 211, and the rings 211 correspond to the through holes on the left and right sides of the moving box 4 respectively.

[0049] The cross section of the ring 211 is arranged to be inclined downward, so as to guide the cleaned sand and gravel to fall back into the moving box 4.

[0050] On the basis of the above-mentioned embodiment, in the process of the reciprocating movement of the mobile box 4 to rub and polish the surface of the cable 100 with sand and stones, some sand and stones are attached to the surface of the cable 100, and in the process of its movement, they are brought out of the outside of the mobile box 4 by the cable 100 through the through hole of the mobile box 4, so that the sand and stones are scattered everywhere, increasing the difficulty of subsequent cleaning, and the reduction of sand and stones inside the mobile box 4 will also reduce the polishing effect of the cable 100; therefore, in the process of the movement of the mobile box 4, the ring 211 is fitted with the surface of the cable 100 to scrape its surface, scrape off the sand and stones attached to the surface, and intercept the sand and stones at the same time, and the cross-section of the ring 211 is set to be inclined downward, which can guide the cleaned sand and stones to fall back into the mobile box 4.

[0051] According to the above working principle, we know that the present invention has the following effects:

[0052] The sand and gravel attached to the surface of the cable 100 are scraped off by the circular ring 211, and the sand and gravel are intercepted to prevent the sand and gravel from being carried out of the moving box 4 by the cable 100, so that the sand and gravel are scattered everywhere, increasing the difficulty of subsequent cleaning. Example 3

[0053] On the basis of Example 2, Figure 1-2 and Figure 7 As shown, it also includes a sleeve 301, an electric push rod 302 and an arc-shaped clamping plate 303; a sleeve 301 is fixedly connected to the through hole on the right side of the moving box 4; two upper and lower symmetrical electric push rods 302 are fixedly connected in the sleeve 301; each electric push rod 302 telescopic part is fixedly connected to an arc-shaped clamping plate 303.

[0054] The arc-shaped clamping plate 303 is provided with a plurality of spikes to facilitate clamping the broken cable 100 and prevent it from swinging around.

[0055] On the basis of the above embodiment, when the fixed plate 2 on the right side moves and stretches the cable 100, due to the high tensile strength of the cable 100 itself, a large pulling force is required to break the cable 100. This causes the broken end of the cable 100 to rebound and swing quickly after being stretched and broken, which may easily injure surrounding staff members by mistake. Therefore, a sleeve 301 is provided at the through hole on the right side of the mobile box 4, and the cable 100 passes through the sleeve 301 to enter the mobile box 4. When the cable 100 is stretched and broken, the tension sensor on the fixed plate 2 detects a decrease in tension, and quickly controls the electric push rod 302 to drive the arc-shaped clamping plate 303 to move, thereby clamping the broken end of the cable 100 to prevent the broken cable 100 from rebounding and swinging, posing a threat to the physical safety of surrounding staff members.

[0056] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
