Description

Technical Field

[0001] The present invention relates to the technical field of alloy resistors, and particularly to an alloy resistor wire per-meter resistance testing machine platform and a testing method thereof. Background Art

[0002] When a manufacturer purchases alloy resistor wire from a supplier, the supplier usually provides alloy resistor wire with a standard circular cross-section. During the actual production process, sometimes the manufacturer will flatten the alloy resistor wire according to the actual situation, so that the cross-section of the alloy resistor wire changes from the original circular shape to an oval shape. This situation belongs to "non-standard" customization. If the manufacturer directly requests "non-standard" customization from the supplier, it is not only difficult for the supplier to supply the goods in a short time, but also the cost price will increase exponentially, which the manufacturer cannot bear.

[0003] In addition, when the cross-section of the alloy resistor wire changes from the original circular shape to an oval shape, since the structure of the alloy resistor wire has deformed, the resistance per unit length will also change accordingly. It is necessary to retest the resistance of the alloy resistor wire after the structure change to detect whether its resistance meets the standard, so as to meet the production requirements.

[0004] Therefore, how to design and develop an alloy resistor wire per-meter resistance testing machine platform and a testing method thereof to solve the above "non-standard" customization problem, change the cross-section of the alloy resistor wire from the original circular shape to an oval shape, and at the same time measure the resistance per unit length of the alloy resistor wire to meet the production requirements is a technical problem to be solved. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide an alloy resistor wire per-meter resistance testing machine platform and a testing method thereof to solve the "non-standard" customization problem, change the cross-section of the alloy resistor wire from the original circular shape to an oval shape, and at the same time measure the resistance per unit length of the alloy resistor wire to meet the production requirements.

[0006] The purpose of the present invention is achieved by the following technical solutions:

[0011] The rolling device, the rice resistance positive electrode testing device, and the rice resistance negative electrode testing device are arranged in sequence along a horizontal straight line.

[0012] In one embodiment, the unwinding device includes an unwinding roller, and the unwinding roller is rotatably arranged on the support frame body.

[0013] In one embodiment, the winding device includes a winding roller and a winding driving motor. The winding roller is rotatably arranged on the reciprocating moving device, and the winding driving motor is used to drive the winding roller to rotate.

[0014] In one embodiment, the rice resistance positive electrode testing device includes a positive electrode testing jaw and a positive electrode testing driving cylinder for driving the opening and closing of the positive electrode testing jaw.

The slide rail is slidably arranged on the horizontal guiding rail, and the reciprocating driving motor is used to drive the slide rail to reciprocate along the horizontal guiding rail.

[0019] A method for testing the rice resistance of an alloy resistance wire is realized by the above alloy resistance wire rice resistance testing machine platform, and includes the following steps:

[0020] Step 1: Provide a wound alloy resistance wire to be rolled. The cross-section of the alloy resistance wire in its initial state is circular, and place the wound alloy resistance wire at the unwinding device;

[0021] Step 2: Start unwinding the alloy resistance wire by the unwinding device, pass one end of the alloy resistance wire through the rolling device, the rice resistance positive electrode testing device, and the rice resistance negative electrode testing device in sequence, and finally wind it at the winding device;

[0022] Step 3: The resistance per meter negative electrode testing device clamps the alloy resistance wire, while the resistance per meter positive electrode testing device does not clamp the alloy resistance wire temporarily.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0040] As Figure 1 And Figure 2 As shown, the present invention discloses an alloy resistance wire rice resistance testing machine 10, which includes: a support frame 100, a pay-off device 200, a take-up device 300, and a reciprocating moving device 400.

[0041] As Figure 1 And Figure 2As shown, the unwinding device 200 is arranged on the support frame 100. The support frame 100 has a horizontal guide rail 110. The reciprocating moving device 400 is slidably arranged on the horizontal guide rail 110. The winding device 300 is arranged on the reciprocating moving device 400.

[0042] The alloy resistance wire meter resistance testing machine table 10 further includes a roller pressing device 500 arranged on the support frame 100 (as Figure 4 shown).

[0043] The support frame 100 is provided with a meter resistance positive electrode testing device 600 (as Figure 3 shown), and the reciprocating moving device 400 is provided with a meter resistance negative electrode testing device 700 (as Figure 6 shown).

[0044] As Figure 2 shown, the roller pressing device 500, the meter resistance positive electrode testing device 600, and the meter resistance negative electrode testing device 700 are arranged in sequence along a horizontal straight line.

[0045] Next, the specific structure of the unwinding device 200 will be described: The unwinding device 200 includes an unwinding roller 210 (as Figure 3 shown). The unwinding roller 210 is rotatably arranged on the support frame 100. In the present invention, the unwinding roller 210 is rotatably arranged on the support frame 100. The unwinding roller 210 does not need to be additionally provided with an electric drive. The coiled alloy resistance wire to be tested is placed on the unwinding roller 210, and the coiled alloy resistance wire rotates on the unwinding roller 210 under the action of tension.

[0046] Next, the specific structure of the winding device 300 will be described: The winding device 300 includes a winding roller 310 and a winding drive motor 320 (as Figure 6 shown). The winding roller 310 is rotatably arranged on the reciprocating moving device 400. The winding drive motor 320 is used to drive the winding roller 310 to rotate. In the present invention, the winding roller 310 is driven to rotate by the winding drive motor 320. One end of the alloy resistance wire is wound around the winding roller 310, and as the winding roller 310 rotates, the alloy resistance wire is rewound into the winding roller 310.

[0047] Next, the specific structures of the meter resistance positive electrode testing device 600 and the meter resistance negative electrode testing device 700 will be described: As Figure 4 shown, the meter resistance positive electrode testing device 600 includes a positive electrode testing jaw 610 and a positive electrode testing drive cylinder 620 for driving the positive electrode testing jaw 610 to open and close; as Figure 6 shown, the meter resistance negative electrode testing device 700 includes a negative electrode testing jaw 710 and a negative electrode testing drive cylinder 720 for driving the negative electrode testing jaw 710 to open and close.

[0048] In the present invention, the positive test jaw 610 is mainly used to clamp or release the alloy resistance wire. When the positive test jaw 610 clamps the alloy resistance wire, it cooperates with the negative test jaw 710 to realize the detection of the resistance value. When the positive test jaw 610 is released, the alloy resistance wire can freely pass through the positive test jaw 610 without restriction.

[0049] In the present invention, the negative test jaw 710 is mainly used to clamp or release the alloy resistance wire. When the negative test jaw 710 clamps the alloy resistance wire, it plays two roles: on the one hand, it cooperates with the positive test jaw 610 to realize the detection of the resistance value; on the other hand, it cooperates with the reciprocating movement device 400 to provide a pulling force for the alloy resistance wire to realize unwinding.

[0050] Next, the specific structure of the rolling device 500 will be described: The rolling device 500 includes an upper pressing roller 510 and a lower pressing roller 520, and the distance between the upper pressing roller 510 and the lower pressing roller 520 is adjustable. The rolling device 500 further includes a rolling drive motor for driving the upper pressing roller 510 and the lower pressing roller 520 to rotate. According to the production requirements, by adjusting the gap between the upper pressing roller 510 and the lower pressing roller 520, an alloy resistance wire with the required dimensions can be rolled out.

[0051] Next, the specific structure of the reciprocating movement device 400 will be described: The reciprocating movement device 400 includes a slide rail 410 (as Figure 6 shown) and a reciprocating drive motor. The slide rail 410 is slidably disposed on the horizontal guide rail 110, and the reciprocating drive motor is used to drive the slide rail 410 to reciprocate along the horizontal guide rail 110. In the present invention, the horizontal guide rail 110 is a horizontal straight line. The slide rail 410 is clamped on the horizontal guide rail 110 by rollers, and the reciprocating drive motor drives the rollers to rotate, thereby causing the slide rail 410 to reciprocate along the horizontal guide rail 110. The winding device 300 and the resistance negative test device 700 for wire length per meter are mounted on the slide rail 410.

[0052] Next, the working principle of the above-mentioned alloy resistance wire resistance per unit length testing machine 10 will be described:

[0053] A roll of alloy resistance wire to be rolled is provided. In its initial state, the cross-section of the alloy resistance wire is circular. It is necessary to perform "non-standard" customization on the alloy resistance wire so that the cross-section of the alloy resistance wire changes from the original circular shape to an oval shape.

[0054] Place the roll of alloy resistance wire 20 at the unwinding device 200.

[0055] The unwinding device 200 starts to unwind the alloy resistance wire, and one end of the alloy resistance wire 20 passes through the rolling device 500, the resistance of positive terminal testing device 600, and the resistance of negative terminal testing device 700 in sequence, and finally winds up at the winding device 300; this step is completed by the production line workers. Since the alloy resistance wire 20 in the front part has not been formally rolled and resistance tested, this front part can be specially marked by the workers and treated as waste;

[0056] Adjust the rolling device 500 so that the upper roller 510 and the lower roller 520 can clamp the alloy resistance wire 20, and the distance is determined according to the actual production requirements;

[0057] As Figure 7 shown, the resistance of negative terminal testing device 700 clamps the alloy resistance wire 20, and the resistance of positive terminal testing device 600 does not clamp the alloy resistance wire temporarily. The reciprocating moving device 400 drives the resistance of negative terminal testing device 700 and the winding device 300 to move away from the rolling device 500. The alloy resistance wire in the unwinding device 200 is pulled and continuously unwound and passes through the rolling device 500, and the rolling device 500 performs rolling treatment on the alloy resistance wire;

[0058] When the reciprocating moving device 400 drives the resistance of negative terminal testing device 700 and the winding device 300 to move away from the rolling device 500, the alloy resistance wire 20 is continuously unwound and stretched. At the same time, the cross-section of the gold resistance wire changes from the original circular shape to an oval shape;

[0059] The reciprocating moving device 400 reaches the specified position and stops moving. The resistance of positive terminal testing device 600 clamps the alloy resistance wire, and the resistance value of the alloy resistance wire 20 between the resistance of positive terminal testing device 600 and the resistance of negative terminal testing device 700 is tested; in this embodiment, when the length of the alloy resistance wire 20 between the resistance of positive terminal testing device 600 and the resistance of negative terminal testing device 700 is 1 meter, the reciprocating moving device 400 stops moving;

[0060] As Figure 8 shown, after the resistance value test is completed, the resistance of negative terminal testing device 700 releases the alloy resistance wire, and the winding device 300 winds up the alloy resistance wire 20. At the same time, the reciprocating moving device 400 moves back to the side close to the rolling device 500 to reset;

[0061] Therefore, it should be particularly noted that while the winding device 300 winds up the alloy resistance wire, the reciprocating moving device 400 moves back to the side close to the rolling device 500 to reset. In this way, the winding device 300 will not continue to apply external force to the alloy resistance wire during the winding process, the alloy resistance wire will not continue to deform, and at the same time, it is ensured that the tested resistance value of the alloy resistance wire is within the specified range;

[0062] Imagine that when the coiling device 300 coils the alloy resistance wire, the reciprocating movement device 400 is still maintained. At the same time, the resistance per meter positive test device 600 releases the alloy resistance wire, allowing the alloy resistance wire to continue to unwind and pass through the rolling device 500. The length of the alloy resistance wire unwound will be longer, and the alloy resistance wire will be pulled thinner and thinner, causing deviation in the alloy resistance wire that has already been rolled and tested, resulting in serious quality problems;

[0063] In addition, it should be noted that an important feature of the present invention is that by using the reciprocating movement device 400 to move back and forth to pull out a specified length of the alloy resistance wire. On the one hand, it will not cause the alloy resistance wire to be pulled too long and thin to produce dimensional deviation. On the other hand, this is also beneficial for the test device to measure the resistance value of the alloy resistance per unit length;

[0064] When there is a resistance value deviation, the test device will send a signal to the control center, and the control center will send an alarm signal to indicate that this section of the alloy resistance wire is a defective product, and workers are required to come to check the problem and make repairs. If the problem cannot be solved, this section of the alloy resistance wire can be specially marked to prevent subsequent misuse;

[0065] After the reciprocating movement device 400 resets, the resistance per meter positive test device 600 releases the alloy resistance wire, and the resistance per meter negative test device 700 clamps the alloy resistance wire again;

[0066] The reciprocating movement device 400 drives the resistance per meter negative test device 700 and the coiling device 300 to move away from the rolling device 5000 again for the next cycle.

[0067] The present invention also discloses a method for measuring the resistance per meter of an alloy resistance wire, which is realized by the above-mentioned resistance per meter test machine for alloy resistance wire, and includes the following steps:

[0068] Step 1: Provide a coiled alloy resistance wire to be rolled. The cross-section of the alloy resistance wire in its initial state is circular, and the coiled alloy resistance wire is placed at the unwinding device;

[0069] Step 2: The unwinding device starts to unwind the alloy resistance wire, and one end of the alloy resistance wire passes through the rolling device, the resistance per meter positive test device, and the resistance per meter negative test device in sequence, and finally is coiled at the coiling device;

[0070] Step 3: The resistance per meter negative test device clamps the alloy resistance wire, and the resistance per meter positive test device does not clamp the alloy resistance wire temporarily. The reciprocating movement device drives the resistance per meter negative test device and the coiling device to move away from the rolling device. The alloy resistance wire in the unwinding device is pulled and continuously unwound and passes through the rolling device, and the rolling device performs a rolling treatment on the alloy resistance;

[0071] Step 4: The reciprocating moving device stops moving when it reaches the specified position. The positive rice resistance testing device clamps the alloy resistance wire and measures the resistance value of the alloy resistance wire between the positive rice resistance testing device and the negative rice resistance testing device.

[0072] Step 5: After the resistance value measurement is completed, the negative rice resistance testing device releases the alloy resistance wire, and the winding device winds up the alloy resistance wire. At the same time, the reciprocating moving device moves back to the side close to the rolling device for reset.

[0073] Step 6: After the reciprocating moving device is reset, the positive rice resistance testing device releases the alloy resistance wire, and the negative rice resistance testing device clamps the alloy resistance wire again.

[0074] Step 7: The reciprocating moving device drives the negative rice resistance testing device and the winding device to move away from the rolling device again for the next cycle.

[0075] An alloy resistance wire rice resistance testing machine platform and its testing method of the present invention solve the problem of "non-standard" customization, change the cross-section of the alloy resistance wire from the original circular shape to an oval shape, and measure the resistance value per unit length of the alloy resistance wire to meet the production requirements.

[0076] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the invention patent shall be subject to the appended claims.
