Technical Field

[0001] The present invention relates to the technical field of detection instruments, and in particular to a resistance detection device and a detection method for a wire. Background Art

[0002] Cables are devices used for power transmission, usually formed by twisting wire conductors. The resistance of the wire conductors forming the cable is an important technical parameter of the cable. Usually, the loss of electric energy in the cable is inversely proportional to the square of the resistance of the wire conductors forming the cable. Therefore, resistance testing of wire conductors has become a necessary step before the wire conductors leave the factory.

[0088] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0089] In the embodiment of the present invention, Figure 1 As shown, a resistance detection device for a wire is provided, which may include:

[0090] A conveying mechanism 100 for conveying the wire of the resistor to be tested;

[0091] A detection mechanism 200, disposed at a first predetermined position, for clamping and detecting the resistance of the wire;

[0092] A first clamping mechanism 300 is disposed above the conveying mechanism 100 and is used to clamp the wire on the conveying mechanism 100 and transfer it to a first predetermined position;

[0093] A shearing mechanism 400 is disposed at a first predetermined position and is used to shear the wire at the first predetermined position.

[0094] The above technical solution can automatically and controllably transport the wire to be tested to a position close to the testing mechanism 200 by setting the conveying mechanism 100, and the first clamping mechanism 300 can clamp the wire on the testing mechanism 200 and move it to the first predetermined position where the testing mechanism 200 is located, and the testing mechanism 200 automatically performs resistance detection on the wire, and the shearing mechanism 400 automatically shears the tested wire into a predetermined number of segments at the first predetermined position. This technical solution can realize automatic conveying of wires, automatic resistance measurement, and automatically shearing the wire into a predetermined number of short segments after the resistance measurement is completed, overcoming the defect that the wire resistance measurement in the prior art requires pure manual labor, and the resistance measurement is automatically completed, which is not prone to errors.

[0095] In a preferred embodiment, Figure 2 As shown, the conveying mechanism 100 may include:

[0096] a conveyor belt structure 101;

[0097] A plurality of U-shaped grooves are disposed on the conveyor belt structure in parallel with each other, and the extending direction of the U-shaped grooves is perpendicular to the conveying direction of the conveyor belt structure 101 .

[0098] In this technical solution, the conveyor belt structure 101 may have an explicit belt structure, such as a belt, a chain belt composed of a metal structure, etc., or may not have an explicit belt structure, such as the space between a pair of sprocket drive structures that are parallel to each other and operate synchronously. The specific structure of the conveyor belt structure 101 may be selected as needed without conflicting with the purpose of the present invention.

[0099] The plurality of U-shaped grooves are used to place wires, and the wires can be placed in the U-shaped grooves for transmission, thereby preventing the wires from being stacked on the conveying mechanism 100 or being positionally shifted. In an embodiment with an explicit belt structure, the U-shaped groove can be connected to the belt structure and operate along with the belt structure, or the U-shaped groove can be directly formed on the belt structure. For example, in an embodiment in which the metal structure is combined into a chain belt structure, the U-shaped groove can be directly formed on the metal structure constituting the chain belt. In an embodiment without a belt structure, the U-shaped groove can be operated along with the transmission structure by connecting both ends of the U-shaped groove to the transmission structure of the conveyor belt structure 101. For example, in a conveyor belt structure implemented by a pair of sprocket transmission structures that are parallel to each other and operate synchronously, the two ends of the U-shaped groove can be respectively connected to the transmission chains of a pair of sprocket transmission structures, so that the U-shaped groove operates along with the pair of sprocket transmission structures. The embodiments described above can also be combined with each other. For example, in an embodiment with an explicit belt structure, the two ends of the U-shaped groove can also be connected to the transmission structure of the conveyor belt structure 101, and the middle part of the U-shaped groove can be supported by the belt structure to place the middle part of the U-shaped groove hanging down.

[0100] Further preferably, in the plurality of U-shaped grooves, a predetermined spacing distance may be set between each U-shaped groove, so that the first clamping mechanism 300 can clamp the wire in the U-shaped groove.

[0101] Further preferably, the length of the U-shaped groove may be smaller than the length of the wire, so that both ends of the wire extend out of the U-shaped groove, so that the first clamping mechanism 300 can clamp the wire in the U-shaped groove at the exposed parts of the wire at both ends of the U-shaped groove.

[0102] In a further embodiment, the conveying mechanism 100 can be configured to operate in a controllable manner, such as each operating distance being the width of a U-shaped groove, and stopping after each operation, waiting for the wire in the U-shaped groove currently closest to the first predetermined position to be taken away before operating again. This type of control can be completed by a simple controller in conjunction with a sensor. For example, the controller can adopt a PLC (Programmable Logic Controller) controller. The sensor can be a pressure sensor arranged in the U-shaped groove to detect whether the wire in the U-shaped groove closest to the first predetermined position is taken away, or it can be an infrared sensor arranged on the conveying mechanism 100 to detect whether the first clamping mechanism 300 has taken the wire from the U-shaped groove. There are many similar options and they will not be repeated one by one.

[0103] In a preferred embodiment, Figure 3 As shown, the first predetermined position includes:

[0104] A first bracket 500 , on which the detection mechanism 200 is disposed.

[0105] The first bracket 500 is arranged at a first predetermined position and serves to fix the detection mechanism 200. In a specific embodiment used to demonstrate the feasibility of the present invention, the first bracket 500 may include a base 501 and a support portion 502, wherein the support portion 502 is arranged on the base 501, and the detection mechanism 200 is connected to the support portion 502.

[0106] Further preferably, the detection mechanism 200 may include:

[0107] A pair of detection components 210 are disposed at two ends of the first bracket 500, and the distance between the pair of detection components 210 is adapted to the length of the wire;

[0108] The pair of first lifting components 220 are respectively connected between the first bracket 500 and the pair of detection components 210 to lift the corresponding detection components 210 to a detection position and lower them to a first initial position.

[0109] In the above technical solution, the detection component 210 is arranged at both ends of the first bracket 500, so as to adapt to the length of the wire. According to the known resistance detection method, in the resistance detection process, it is usually necessary to connect the object to be tested in series or in parallel to the circuit, and realize resistance detection by applying a voltage or current of a predetermined size and detecting the current change or voltage change of the object to be tested. The clamping position of the bar-shaped object to be tested is directly related to the actual length of the bar-shaped object to be tested that is connected in series or in parallel to the circuit. Therefore, the detection component 210 is arranged at both ends of the first bracket 500, so that the detection component 210 can clamp the two ends of the wire when performing resistance detection, thereby detecting the resistance of the wire to the greatest extent.

[0110] On this basis, further, the detection component 210 can be in a first initial position before the detection starts. When the detection starts, when the first clamping mechanism 300 clamps the wire to above the first predetermined position, a pair of first lifting components 220 respectively lifts the corresponding detection components 210 to the detection position. After the pair of detection components 210 clamp the wire, the first clamping mechanism 300 releases the wire.

[0111] Further preferably, the first lifting component 220 may include a first track 221, which is longitudinally arranged on the support portion 502 of the first bracket 500, and the detection component 210 is connected to the first track 221 so as to be slidable up and down. The first lifting component 220 also includes a first telescopic element 222, which is respectively connected to the support portion 502 and the corresponding detection component 210, and when the first telescopic element 222 is extended, it pushes the detection component 210 to slide upward along the first track 221 to the detection position, and when the first telescopic element 222 is retracted, it pulls the detection component 210 to slide downward along the first track 221 to the first initial position.

[0112] In an optional embodiment, the relationship between the first initial position and the detection position may not be the relationship described above, but may be that the first initial position is on top and the detection position is on the bottom, or that the first initial position and the detection position are in a forward and backward relationship, or in a positional relationship in an inclined direction. The above-mentioned various changes can be achieved by correspondingly changing the route of the first clamping mechanism 300 to move the wire, and the positional relationship between the pair of detection components 210 and the pair of first lifting components 220. For example, if the route of the first clamping mechanism 300 to move the wire is changed from bottom to top, and the direction of the pair of detection components 210 is changed, the first initial position can be on top and the detection position can be on the bottom. If the pair of detection components 210 and the pair of first lifting components 220 are arranged horizontally, the first initial position and the detection position can be in a forward and backward relationship. Similarly, the positional relationship in the inclined direction can be achieved by tilting the pair of detection components 210 and the pair of first lifting components 220.

[0113] Further preferably, the detection component 210 may include:

[0114] a first clamping jaw 211, the first clamping jaw 211 comprising a clamping portion for clamping a wire;

[0115] A detection contact is arranged on the clamping portion;

[0116] Detection circuit, connect the detection contacts.

[0117] In this technical solution, the clamping portion of the first clamping jaw 211 can be made of insulating material, and the detection contact can be made of conductive material, thereby preventing the clamping portion of the first clamping jaw 211 from being conductively connected to the wire to form a loop.

[0118] Optionally, the clamping portion can also be made of conductive material, that is, the clamping portion can form a detection contact, and the connection between the clamping portion and the first clamping jaw 211 can be isolated by insulating material, thereby preventing other conductive material parts of the first clamping jaw 211 from being conductive to the wire to form a loop.

[0119] The detection contacts are connected to the detection circuit, and voltage or current is applied to the detection contacts through the detection circuit. When the first jaws 211 of a pair of detection components 210 clamp the two ends of the wire, the contacts of the two first jaws are connected to the wire, so that voltage or current is applied to the two ends of the wire to perform resistance detection on the wire.

[0120] Further preferably, the first clamp 211 may be one of a pneumatic clamp, a hydraulic clamp and an electric clamp.

[0121] Further preferably, the first telescopic element 222 may be one of a hydraulic cylinder, a pneumatic cylinder, an electric cylinder, a screw lifting mechanism, a rack lifting mechanism, a chain lifting mechanism and a belt lifting mechanism.

[0122] In a preferred embodiment, Figure 4 As shown, the first clamping mechanism 300 may include:

[0123] a first moving structure 310;

[0124] A first lifting structure 320 connected to the first moving structure 310;

[0125] A first clamping structure 330 is connected to the first lifting structure 320 .

[0126] In this technical solution, the first moving structure 310 can provide a moving range within a plane defined by the X-axis and the Y-axis, and the first lifting structure 320 can provide a moving range in the Z-axis direction. On this basis, the first moving structure 310 can adopt one of an electric bridge guide rail, an electric gantry guide rail, and an electric manipulator. When the moving direction of the wire only needs to move in a straight line, the X-axis direction can be locked as needed, that is, the driving element in the X-axis direction can be omitted, or the Y-axis direction can be locked, that is, the driving element in the Y-axis direction can be omitted. Figure 4 In the embodiment shown, the first moving structure 310 uses an electric bridge guide rail and locks the Y axis. Further, the first lifting structure 320 can use one of a screw guide rail, a rack guide rail, a chain guide rail and a belt guide rail.

[0127] As an optional embodiment, the first mobile structure 310 and the first lifting structure 320 can be formed by a multi-axis robotic arm. Forming the first mobile structure 310 and the first lifting structure 320 by a multi-axis robotic arm can achieve a larger range of activities and more varied moving routes, thereby better adapting to on-site needs.

[0128] Further preferably, Figure 5 As shown, the first clamping structure 330 may include:

[0129] A second bracket 331 connected to the lifting structure;

[0130] A straightening component 332 is connected to the second bracket 331 .

[0131] In this technical solution, the straightening component 332 can straighten the wire when clamping the wire to prevent the wire from bending.

[0132] On this basis, further, the straightening component 332 may include:

[0133] A pair of slide rails 3321 are respectively disposed at two ends of the second bracket 331;

[0134] A pair of second clamping jaws 3322 are slidably connected to corresponding slide rails 3321 in the pair of slide rails 3321;

[0135] A pair of push-pull components 3323 are respectively connected to the second bracket 331 and the corresponding second clamping jaws 3322 to push and pull the second clamping jaws 3322 between a second initial position and a straightening position.

[0136] In this technical solution, a pair of second clamping jaws 3322 are slidably connected to a pair of slide rails 3321 at both ends of the second bracket 331. When the first clamping mechanism 300 clamps the wire on the conveying mechanism 100, the pair of second clamping jaws 3322 clamp the two ends of the wire. The first clamping mechanism 300 lifts the first clamping structure 330 through the first lifting structure 320, that is, the pair of second clamping jaws 3322 are lifted while clamping the wire. At this time, a pair of push-pull components 3323 push the pair of second clamping jaws 3322 to move along the pair of slide rails 3321 toward the two ends of the second bracket 331, so that the wire clamped by the pair of second clamping jaws 3322 at both ends is stretched, thereby achieving the purpose of straightening the wire.

[0137] On this basis, preferably, the second clamp 3322 can be one of a pneumatic clamp, a hydraulic clamp and an electric clamp.

[0138] On this basis, preferably, the push-pull component 3323 can be one of a hydraulic cylinder, a pneumatic cylinder, an electric cylinder, a screw push-pull mechanism, a rack push-pull mechanism, a chain push-pull mechanism and a belt push-pull mechanism.

[0139] Further preferably, the first clamping structure 330 may further include a first clamping component, and the first clamping component may include:

[0140] At least two third clamping jaws 334 are respectively disposed at the middle of the second bracket 331 , and there is a first preset distance between each of the at least two third clamping jaws 334 .

[0141] In this technical solution, the function of the first clamping component can be to clamp the wire in the middle of the wire clamped at both ends to prevent the middle of the wire from bending downward. Preferably, the first clamping component can clamp the middle of the wire after the wire is straightened, that is, the first clamping component does not work when the first clamping mechanism 300 clamps the wire on the conveying mechanism 100, and at least two third clamping jaws 334 are in an open state. When a pair of second clamping jaws 3322 clamp the wire and are lifted, and a pair of second clamping jaws 3322 are pushed by the corresponding push-pull components 3323 to move along a pair of slide rails 3321 to the two ends of the second bracket 331 to straighten the wire, the middle of the wire that was originally in a bent and drooping state will be lifted along with the straightening. At this time, at least two third clamping jaws 334 of the first clamping component are opened and clamp the middle of the wire to prevent the wire from bending and sagging in the middle during movement.

[0142] On this basis, preferably, the third clamp 334 can be one of a pneumatic clamp, a hydraulic clamp and an electric clamp.

[0143] In a preferred embodiment, Figure 6 As shown, the shearing mechanism 400 may be disposed on a supporting portion 502 on a first bracket 500 and located between a pair of detection components 210 .

[0144] In this technical solution, the shearing mechanism 400 is arranged between a pair of detection components 210. When the pair of detection components 210 clamp the two ends of the wire and complete the resistance detection, the shearing mechanism 400 can directly shear the wire between the pair of detection components 210, avoiding the equipment cost caused by moving the wire again for shearing.

[0145] On this basis, further, the shearing mechanism 400 may include:

[0146] At least one shearing component 410 is disposed on the support portion 502 of the first bracket 500, and the position of the shearing component 410 on the first bracket is adapted to the size of the wire shearing;

[0147] The second lifting components 420 corresponding to the number of the shearing components 410 are connected between the first bracket 500 and the corresponding shearing components 410 to lift the corresponding shearing components 410 to a shearing position and lower them to a third initial position.

[0148] In this technical solution, the number of shearing components 410 provided may be related to the number of segments that the wire needs to be sheared. For example, if the wire needs to be sheared into two segments, only one shearing component 410 is required, and the length of each segment after the wire is sheared into two segments can be controlled by adjusting the position of the shearing component 410 on the support portion 502 of the first bracket 500. If the wire needs to be sheared into three segments, two shearing components 410 may be provided, and the length of each segment after the wire is sheared into three segments can also be controlled by adjusting the position. The same can be applied when the wire needs to be sheared into more segments.

[0149] When the pair of detection components 210 clamp the wire for resistance detection, the shearing component 410 can be in the third initial position, so as not to interfere with the work of the pair of detection components 210. After the pair of detection components 210 complete the resistance detection of the wire, the second lifting component 420 pulls the shearing component 410 to rise to the shearing position. On this basis, the second lifting component 420 can include a second track 421, the second track 421 is longitudinally arranged on the support portion 502 of the first bracket 500, and the shearing component 410 can be connected to the second track 421 in a sliding manner up and down. The second lifting component 420 also includes a second telescopic element 422, which is respectively connected to the support portion 502 and the corresponding shearing component 410. When the second telescopic element 422 is extended, it pushes the shearing component 410 to slide upward along the second track 421 to the shearing position, and when the second telescopic element 422 is retracted, it pulls the shearing component 410 to slide downward along the second track 421 to the third initial position.

[0150] Since the detection position and the shearing position correspond to different parts of the wire, it can be understood that the detection position and the shearing position are on the same straight line. Therefore, the relationship between the shearing position and the third initial position can be set in the same or corresponding manner as the relationship between the detection position and the first initial position in the embodiment of the detection mechanism 200.

[0151] On this basis, optionally, the shearing component 410 can be one of pneumatic shearing pliers, hydraulic shearing pliers and electric shearing pliers.

[0152] On this basis, optionally, the second telescopic element 422 can be one of a hydraulic cylinder, a pneumatic cylinder, an electric cylinder, a screw lifting mechanism, a rack lifting mechanism, a chain lifting mechanism and a belt lifting mechanism.

[0153] Further preferably, N shearing components 410 may be provided, where N is a natural number greater than 1. Providing N shearing components 410 may shear the wire into N+1 segments.

[0154] On this basis, a second preset distance may be provided between every two adjacent shearing components 410 of the N shearing components 410. When the shearing mechanism 400 shears the wire, both ends of the wire are clamped by the detection component 210. If only one or more shearing components 410 are provided, an additional clamping structure may be provided at the second preset distance between every two adjacent shearing components 410 to keep the wire stable when being sheared.

[0155] In a preferred embodiment, Figure 7 As shown, a second clamping mechanism 600 may also be included. The second clamping mechanism 600 is used to clamp the wire between every two adjacent shearing components 410 when the shearing mechanism shears the wire. By clamping the wire between every two adjacent shearing components 410 by the second clamping mechanism 600, the wire can be kept stable when being sheared, and bending of the wire caused by shearing can be avoided.

[0156] On this basis, optionally, the second clamping mechanism 600 can also be configured to clamp the cut wire between every two adjacent shearing components 410 and move it to a second predetermined position.

[0157] Further preferably, the second clamping mechanism 600 can be configured to not only clamp the wire between every two adjacent shearing parts 410 when the wire is sheared, but also clamp the cut wire between every two adjacent shearing parts 410. The second predetermined position can be a device for storing the cut wire, such as a material frame, or another conveying device to convey the cut wire to other operation links.

[0158] On this basis, further preferably, the second clamping mechanism 600 includes:

[0159] a second mobile structure 610;

[0160] a second lifting structure 620 connected to the second moving structure 610;

[0161] N-1 second clamping components 630 are connected to the second lifting structure 620 , and each second clamping component 630 corresponds to two adjacent shearing components 410 .

[0162] In this technical solution, the second movable structure 610 can provide a moving range within a plane determined by the X-axis and the Y-axis, and the second lifting structure 620 can provide a moving range corresponding to the Z-axis. Therefore, the implementation methods of the first movable structure 310 and the first lifting structure 320 described above can be applied to the second movable structure 610 and the second lifting structure 620, and will not be repeated here.

[0163] N-1 second clamping components are simultaneously connected to the second lifting structure 620 and can move with the second lifting structure 620, so as to clamp the wire between every two adjacent shearing components 410 and clamp the cut wire between every two adjacent shearing components 410 at one time.

[0164] On this basis, it is further preferred that Figure 8 As shown, the second clamping member 630 includes:

[0165] a third bracket 631 connected to the second lifting structure 620 and moving with the second lifting structure 620;

[0166] A pair of fourth clamping jaws 632 is connected to the third bracket 631 .

[0167] In this technical solution, a pair of fourth clamping jaws 632 are provided to provide two clamping points. Whether clamping the wire between every two adjacent shearing parts 410 when the wire is sheared, or clamping the cut wire between every two adjacent shearing parts 410, good stability can be provided to avoid deformation of the wire during shearing or shaking of the wire during clamping due to a single clamping point.

[0168] On this basis, preferably, the fourth clamp 632 can be one of a pneumatic clamp, a hydraulic clamp and an electric clamp.

[0169] In an optional embodiment, N-1 second clamping mechanisms 600 may be provided, and each second clamping mechanism 600 is used to clamp the wire between every two adjacent shearing components 410 when the shearing mechanism 400 shears the wire.

[0170] On this basis, optionally, N-1 second clamping mechanisms 600 can also be configured to clamp the corresponding cut wires located between two adjacent shearing components 410 and move them to the second predetermined position.

[0171] Further preferably, the N-1 second clamping mechanisms 600 may be configured to not only clamp the wire between every two adjacent shearing components 410 when the wire is sheared, but also clamp the cut wire between every two adjacent shearing components 410 .

[0172] In this technical solution, the N-1 second clamping mechanisms 600 can work synchronously or in a preset order. On this basis, the second predetermined position can be one or divided into multiple positions. For example, in an implementation using a material frame, only one material frame can be used to correspond to the N-1 second clamping mechanisms 600, or a common material frame can be configured for several second clamping mechanisms 600 among the N-1 second clamping mechanisms 600, or an independent material frame can be configured for each second clamping mechanism 600 among the N-1 second clamping mechanisms 600.

[0173] In a preferred embodiment, the first clamping mechanism 300 is further configured to clamp the cut wire between the detection mechanism 200 and the shearing mechanism 400 and move it to a third predetermined position.

[0174] In this technical solution, since the two ends of the wire are clamped by a pair of detection components 210 of the detection mechanism 200, and the second clamping mechanism 600 clamps the cut wire between every two adjacent shearing components 410, the wire clamped between the detection component 210 and the adjacent shearing component 410 can be clamped by the first clamping mechanism 300 and moved to the third predetermined position.

[0175] In an optional embodiment, the first clamping mechanism 300 can also be configured to clamp the cut wire between the detection mechanism 200 and the shearing mechanism 400, and clamp the cut wire between every two adjacent shearing components 410, and move to the third predetermined position. That is, in this embodiment, the second clamping mechanism 600 is no longer needed to clamp the cut wire between every two adjacent shearing components 410. Further, the first clamping mechanism 300 can directly clamp the wire between every two adjacent shearing components 410 when the shearing mechanism 400 shears the wire, so there is no need to configure the second clamping mechanism 600. In this embodiment, N-1 second clamping components 630 can be configured on the first clamping mechanism 300 to realize the role of the first clamping mechanism 300 replacing the second clamping mechanism 600.

[0176] On this basis, preferably, the third predetermined position may also be a material frame. Fig. 9As shown, the third predetermined position 700 can be set between the conveying mechanism 100 and the detection mechanism 200, so that the first clamping mechanism 300 can dispose of the clamped cut wire without moving too much distance after clamping the cut wire between the detection mechanism 200 and the shearing mechanism 400, or after clamping the cut wire between every two adjacent shearing parts 410. In a specific embodiment, the detection mechanism 200 is set on the side of the support portion 502 of the first bracket 500 facing away from the conveying mechanism 1, and the third predetermined position 700 is set between the first bracket 500 and the conveying mechanism 100. On this basis, preferably, a guide structure 503 can be provided on the side of the first bracket 500 facing the conveying mechanism 100, and after the first clamping mechanism 300 clamps the cut wire between the detection mechanism 200 and the shearing mechanism 400, or simultaneously clamps the cut wire between every two adjacent shearing components 410, it only needs to move to the top of the guide structure 503 to release the cut wire, so that the cut wire falls onto the guide structure 503 and enters the third predetermined position 700 under the guidance of the guide structure 503. This technical solution allows the first clamping mechanism 300 to move a very short distance to dispose of the clamped cut wire after clamping the cut wire between the detection mechanism 200 and the shearing mechanism 400, or after clamping the cut wire between every two adjacent shearing components 410 at the same time, thereby improving the working efficiency of the first clamping mechanism 300, and the third predetermined position 700 can be set below the conveying mechanism 100 through the guiding structure 503, thereby making full use of the space and reducing the area occupied by the resistance detection device.

[0177] As an optional embodiment, the guide structure 503 may be as follows Fig. 9 The slope shown can also be a curved surface or a conveyor belt structure. Guide guard plates adapted to the length of the cut wire can be added on both sides of the slope, curved surface, or conveyor belt structure to prevent the cut wire from sliding off the two sides of the guide structure 503.

[0178] Various embodiments of the wire resistance detection device provided by the present invention are described above. It should be noted that the above embodiments and features in the embodiments can be combined with each other without violating the purpose of the present invention.

[0179] The technical solution of the present invention also provides a method for detecting resistance of a wire, which comprises:

[0180] A conveying mechanism is provided to convey the wire material of the resistor to be tested;

[0181] Providing a first clamping mechanism to clamp the wire on the conveying mechanism to a first predetermined position;

[0182] Providing a detection mechanism to clamp and detect the resistance of the wire at a first predetermined position;

[0183] A shearing mechanism is provided to shear the wire at a first predetermined position.

[0184] In order to reflect the feasibility of the above technical solution, a specific embodiment of a conveying mechanism, a first clamping mechanism, a detection mechanism and a shearing mechanism is now described. Those skilled in the art can understand that this specific embodiment is only for illustration and cannot be used to limit the scope of protection of the present invention.

[0185] like Fig.10 In the illustrated embodiment, the conveyor belt structure 101 of the conveying mechanism 100 has an explicit belt-shaped structure; the first moving structure 310 of the first clamping mechanism 300 adopts an electric bridge guide rail, the first lifting structure 320 adopts a screw lifting mechanism, and the Y axis is locked, and two third clamping claws 334 are provided in the first clamping component; the shearing mechanism 400 is provided with two shearing components 410; a second clamping mechanism 600 is provided, and the second moving structure 610 and the second lifting structure 620 of the second clamping mechanism 600 are formed by a multi-axis mechanical arm, and only one second clamping component 630 is provided. In this embodiment, the second clamping mechanism 600 is configured to not only clamp the wire between every two adjacent shearing components 410 when the wire is sheared, but also clamp the cut wire between every two adjacent shearing components 410 and move it to the third predetermined position; the first clamping mechanism 300 is configured to clamp the cut wire between the detection mechanism 200 and the shearing mechanism 400, and move it to the third predetermined position. The specific functions of each mechanism and the structures, components and elements in each mechanism have been described in detail above, so they will not be repeated here.

[0186] In a preferred embodiment, after the first clamping mechanism 300 clamps the wire on the conveying mechanism 100 , it stretches the wire from both ends to align the wire to prevent the wire from bending.

[0187] On this basis, the first clamping mechanism 300 also clamps the wire from the middle of the wire after the wire is straightened to prevent the wire from bending or sagging in the middle during movement.

[0188] On this basis, further, when the first clamping mechanism 300 clamps the wire to the first predetermined position, the detection mechanism 200 rises from a first initial position to a detection position to clamp both ends of the wire and perform resistance detection on the wire;

[0189] On this basis, further, the first clamping mechanism 300 releases the wire after the detection mechanism 200 clamps the wire.

[0190] On this basis, further, after the resistance detection of the wire is completed, the cutting mechanism 400 rises from a third initial position to a cutting position, and cuts the wire into a predetermined number of segments.

[0191] On this basis, further, the shearing mechanism 400 provides N shearing points located between a pair of detection components 210 of the detection mechanism 200 to cut the wire into N+1 segments, where N is a natural number greater than 1. In the present embodiment, N=2, and the wire is cut into three segments by two shearing components 410.

[0192] On this basis, further, a second clamping mechanism 600 is provided to clamp the cut wire between every two adjacent shearing points and move the wire to a second predetermined position.

[0193] On this basis, further, the first clamping mechanism 300 clamps the cut wire between the detection component 210 of the detection mechanism 200 and the shearing component 410 of the shearing mechanism 400 , and moves to a third predetermined position 700 .

[0194] This technical solution can realize automatic detection of wires, overcome the defects of purely manual and error-prone methods in the prior art, and improve detection efficiency and accuracy.

[0195] The technical solution of the present invention also provides a wire resistance detection system, such as Fig.11 As shown in the figure, the above-mentioned resistance detection device is included, and further includes:

[0196] A control unit, the signal of which is connected to the detection mechanism, for collecting the resistance value detected by the detection mechanism;

[0197] A sending unit, connected to the control unit, for sending the resistance value collected by the control unit;

[0198] A management system is signal-connected to the sending unit and is used to receive the resistance value sent by the sending unit.

[0199] In this technical solution, the control unit collects the resistance value obtained by the detection mechanism and sends it to the management system through the sending unit, thereby realizing automatic collection of the resistance detection data of the wire and automatic data exchange with the external system.

[0200] Based on the above technical solution, preferably, a storage module can be provided in the control unit to store the resistance value detected by the detection mechanism.

[0201] Based on the above technical solution, preferably, the sending unit can adopt a wireless sending module, such as a wireless LAN signal transmitting module, a mobile network signal transmitting module, a Bluetooth signal transmitting module, a Zifeng signal transmitting module, etc. The optional sending unit can also be a wired network adapter, such as an Ethernet adapter, a fiber optic adapter, etc.

[0202] Based on the above technical solution, preferably, the management system can adopt an MES (manufacturing execution system) system so that the resistance detection data of the wire can directly enter the MES system of the factory, thereby improving the factory's real-time control capabilities of product parameters. Optionally, the above management system can also be a cloud platform, which can save the resistance detection data of the wire or perform cloud computing through the cloud platform.

[0203] The wire material mentioned in the technical solution of the present invention can be an aluminum single wire.

[0204] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
