[0030] In order to solve the problems in the background technology, the core inventive concept of the present invention is: using a wire clamping device to clamp a batch of wires at the same time, and electrically connecting the conductivity measuring device to the wire clamping device, so that the conductivity of a batch of wires can be measured at the same time, and when measuring the conductivity of the next batch of wires, there is no need to rewire, which is conducive to improving measurement efficiency.

[0031] The present invention is further described in detail below in conjunction with embodiments.

[0032] Specific embodiments of the conductor conductivity measurement system provided by the present invention: In the present invention, in order to facilitate the understanding of the present solution by those skilled in the art, the front-to-back direction and the left-to-right direction are defined. In actual production, the specific directions may be different depending on the perspective of the observer. In this case, the arrangement direction of each clamping member group is the left-to-right direction in the present invention, and the movement direction of each clamping member is the front-to-back direction in the present invention.

[0033] like Figures 1 to 9 As shown, as a basic specific implementation, the conductor conductivity measurement system includes a conductivity measurement device, a programmable logic controller 700 , a host computer 100 communicatively connected to the conductivity measurement device, and a conductor clamping device 500 .

[0034] The wire clamping device 500 includes a guide support component, on which at least two clamping member groups 3 are arranged at intervals on the left and right, each clamping member group 3 includes at least three clamping members that cooperate with the guide support component to move forward and backward, each clamping member group 3 is configured with a driving structure for driving the clamping members therein to clamp the same batch of wires 600 at the same time, each clamping member is used to cooperate with an adjacent clamping member to clamp a corresponding single wire 600, and each clamping member group 3 is used to clamp different parts of the batch of wires 600; At least two clamping member groups 3 constitute a conductive clamping member group, in which at least one of the two clamping members for clamping the same wire 600 is provided with a conductive portion 6 for contacting and conducting with the corresponding single wire 600; The conductive parts 6 of at least two conductive clamping parts are used to be electrically connected to the conductivity measuring device. The programmable logic controller 700 is used to control the conductivity measuring device to sequentially measure the current flowing through each wire 600 and the voltage of the corresponding part of each wire 600. The conductivity measuring device is used to send the measured data (i.e., current data and voltage data) or processed data (i.e., resistance data) to the host computer 100. The host computer 100 is used to calculate the conductivity based on the received data and the cross-sectional area of ​​the wire 600.

[0035] In the present invention, the clamp is preferably a clamp block, and the conductive part 6 is made of conductive materials such as copper and aluminum. The conductive part 6 can be a conductive coating provided on the clamp body or a conductive sheet adhesively mounted on the clamp body.

[0036] In the present invention, “the conductive portion 6 for contacting and conducting with the corresponding single conductive wire 600 ” means that each conductive portion 6 is only electrically connected to a single conductive wire 600 , and two adjacent conductive wires 600 cannot be directly conducted through the conductive portion 6 .

[0037] Among them, the clamping member body can be made of insulating material to prevent adjacent wires 600 from being directly connected through the clamping member, or, for any conductive clamping member group, the clamping member can be made of conductive material as a whole. In this case, the two clamping members form a pair, each pair of clamping members clamps different wires 600 respectively, and each pair of clamping members is separated by an insulating member (such as an elastic member made of insulating material), and the part of the clamping member used to contact the wire 600 constitutes the conductive part 6.

[0038] In the present invention, the number of clamping member groups 3 can be two, three, four or more. When the number of clamping member groups 3 is greater, more parts of the wire 600 are clamped, and the stability of the wire 600 is better. When the number of clamping member groups 3 is smaller, the number of clamping members clamping the same wire 600 is smaller, the structure is simpler, and the number of clamping members that need to be moved when clamping a wire 600 is smaller, and the operation is more convenient. Therefore, technical personnel in this field can select the number of clamping member groups 3 according to actual needs.

[0039] In the conductive clamping member group, for two clamping members clamping the same conductive wire 600, the conductive portion 6 may be provided on one of them, or on both of the clamping members.

[0040] In the present invention, the number of conductive clamping member groups may be two, three, four or more. The number of conductive clamping member groups may be the same as the number of clamping member groups 3 (i.e., all clamping member groups 3 constitute conductive clamping member groups) or different (i.e., some clamping member groups 3 constitute conductive clamping member groups).

[0041] Preferably, all the clamping member groups 3 constitute conductive clamping member groups. In this case, the structures of all the clamping member groups 3 are consistent, which is convenient for production and manufacturing.

[0042] Meanwhile, the total number of the conductive clamping member groups and the number of the conductive clamping member groups electrically connected to the conductivity measuring device may be the same as or different from each other.

[0043] For example, in one embodiment, Figures 1 to 5As shown, there are four groups of conductive clamping components. The two groups of conductive clamping components on the left and right sides are used to connect to the power supply and current measurement circuit 400, and the two groups of conductive clamping components in the middle are used to connect to the voltage measurement circuit 300. The distance between the two groups of conductive clamping components in the middle is one meter. At this time, the length L For one meter, the conductivity Simplified to , which is beneficial to saving computing power. L is the length of the corresponding portion of the wire 600, R is the resistance of the corresponding portion of the wire 600, A is the cross-sectional area of ​​the corresponding portion of the conductor 600.

[0044] In another specific embodiment, the number of the conductive clamping member groups is three, and only two conductive clamping member groups at the edges are electrically connected to the conductivity measuring device.

[0045] In another specific embodiment, referring to Figure 1 As shown, there are four conductive clamping member groups, and the power supply and current measurement circuit 400 and the voltage measurement circuit 300 are both connected to the two conductive clamping member groups on the left and right sides.

[0046] In the present invention, Figure 1 As shown, the conductivity measuring device can be a conductivity measuring instrument 200 (including a power supply module, a current measuring module and a voltage measuring module), and the conductivity measuring instrument 200 is electrically connected to the corresponding conductive clamping component group through a power supply and current measuring circuit 400 and a voltage measuring circuit 300; or, the conductivity measuring device includes a power supply, a voltmeter and an ammeter, and the power supply and the ammeter are connected in series and electrically connected to the corresponding conductive clamping component group through the power supply and current measuring circuit 400, and the voltmeter is electrically connected to the corresponding conductive clamping component group through the voltage measuring circuit 300.

[0047] In the present invention, the output mode of the programmable logic controller 700 (PLC) is relay output. Through programming software such as GX Works, the PLC can accurately control the on and off of the current in each wire 600, thereby realizing the sequential measurement of each wire 600.

[0048] Specifically, all the wires 600 are in contact with the corresponding conductive parts 6, and all the wires 600 are located in different branches. The PLC controls each branch to be turned on separately in turn. The power supply module (power supply) and the current measurement module (ammeter) are located on the main line to measure the current flowing through a single wire 600. The voltage measurement module (voltmeter) is simultaneously connected in parallel with all the wires 600 to measure the voltage of the corresponding part of a single wire 600.

[0049] like Figures 2 to 8As shown, the guide support component includes at least two guide plates 12 and a connecting seat 11 connecting all the guide plates 12. The number of the guide plates 12 is the same as the number of the clamping member groups 3. The guide plate 12 is provided with a guide groove extending forward and backward, and each clamping member is provided with a guide protrusion 7 that slides with the guide groove. Of course, the guide protrusion extending forward and backward can also be provided on the guide plate 12, and a corresponding guide groove can be provided on the clamping member. According to actual needs, the guide groove can be a straight groove or a dovetail groove. Preferably, the guide groove is a through groove, so that the clamping member can be installed from the front and rear sides of the guide plate 12.

[0050] The guide plate 12 is provided with vertical bolt holes, and the connection seat 11 is provided with threaded holes. The bolts penetrate the guide plate 12 and are connected to the connection seat 11 to fix the guide plate 12 to the connection seat 11. Of course, the guide support component can also be an integrally formed rectangular base, and the rectangular base is provided with corresponding guide grooves.

[0051] The driving structure may be an elastic member, or a direct-acting driving device such as an electric telescopic rod installed on the guide plate 12. When the wire clamping device 500 is used to clamp the wire 600, the two clamping members are first separated, and then the wire 600 is passed through the gap between the two clamping members. Finally, under the action of the driving structure, the clamping members clamp the corresponding wire 600.

[0052] In the present invention, the wire clamping device 500 is used to clamp the same batch of wires 600 (i.e., at least two wires 600, for example, twenty wires), and the conductivity measuring device is controlled by PLC to measure each wire 600 in turn, and then the upper computer 100 calculates the conductivity of each wire 600 (the cross-sectional area of ​​the wire 600). A The cross-sectional area is measured by existing measuring equipment such as a micrometer. A It can be manually input into the host computer 100 or transmitted to the host computer 100 by an existing measuring device), thereby realizing large-scale and high-throughput measurement of the wire 600 and improving the measurement efficiency of the conductivity of the wire 600. At the same time, after measuring a batch of wires 600, the next batch of wires 600 can be directly replaced without rewiring the wire clamping device 500 and the conductivity measuring device, which is conducive to improving the measurement efficiency.

[0053] To facilitate clamping of the conductor 600, Figures 2~9As shown, preferably, in a specific embodiment, among the two clamping members for clamping the same wire 600, one of the clamping members has a groove 9 for accommodating the corresponding wire 600, and the other clamping member has a pressing portion for extending into the groove 9 and pressing the wire 600. When the clamping member is used to clamp the wire 600, the wire 600 can be first passed through the groove 9, and the groove wall of the groove 9 can temporarily support the wire 600, so that the wire 600 is conveniently placed between the two clamping members.

[0054] In other specific embodiments, each clamping member is a rectangular clamping block, the guide support component is located at the lower part of the wire 600, and the guide support component is used to directly support the wire 600. When in use, the wire 600 passes through the gap between the two clamping members, and the wire 600 is directly supported by the guide support component.

[0055] Preferably, if Figures 2~9 As shown, in a specific embodiment, for a clamping member having a conductive portion 6, the conductive portion 6 is used to extend into a corresponding groove 9 and constitute the pressing portion, and the structure is simple. For example, a protrusion 8 is provided on the clamping member, and the conductive portion 6 is a conductive sheet disposed on the protrusion 8, and the conductive sheet constitutes the pressing portion.

[0056] In other specific implementations, the conductive portion 6 may also be provided on the groove wall of the corresponding groove 9, and the pressing portion is a pressing protrusion on the clamping member.

[0057] Preferably, if Figures 2~9 As shown, in a specific embodiment, each clamping member group 3 includes at least two sub-clamping member groups, each sub-clamping member group includes at least two clamping members, and the driving structure is an elastic member arranged between two adjacent clamping member groups 3; for any clamping member group 3, the wire clamping device 500 also includes a limiting portion, which is used to limit the extreme position of the clamping member at the outermost edge, and the limiting portion cooperates with the elastic member to enable each clamping member group 3 to clamp the corresponding wire 600.

[0058] exist Figures 2~5 In the embodiment, the elastic member is a spring 4, and there are two sub-clamping member groups. When installing the wire 600, start from the clamping member close to the spring 4 and move different clamping members in sequence. After the clamping member is released, since the clamping member at the edge is limited, the spring 4 can enable the adjacent clamping member to clamp the corresponding wire 600. Of course, for any clamping member group 3, the sub-clamping member groups can also be three, four or more, and springs 4 are provided between adjacent sub-clamping member groups.

[0059] Of course, in other specific implementations, elastic members may also be provided on both the front and rear sides of the clamping member group 3 .

[0060] In a specific embodiment, the guide plate 12 and the connecting seat 11 constitute a base, and each clamping member group 3 is equipped with a gantry 2 detachably connected to the base, and the gantry 2 includes two vertical plates and a horizontal plate connecting the upper ends of the two vertical plates, and the two opposite side walls of the two vertical plates constitute the limiting portion. Among them, the vertical plates are provided with bolt through holes extending in the front-to-back direction, and the guide plate 12 is provided with threaded holes. Bolts pass through the bolt through holes and are connected to the threaded holes to fix the gantry 2 and the guide plate 12.

[0061] Preferably, the transverse plate is also a guide plate 12, that is, the transverse plate also cooperates with the corresponding clamping member group 3 to guide and move along the front-back direction. At this time, the gantry 2, the connecting seat 11 and the guide plate 12 together constitute a guide support component.

[0062] Alternatively, the guiding support component only includes a support seat and a gantry 2 connected to the support seat, the transverse plate of the gantry 2 cooperates with the clamping member group 3 to guide movement along the front-to-back direction, and the support seat is used to support the clamping member; alternatively, the guiding support component only includes the gantry 2, the transverse plate of the gantry 2 is provided with a dovetail groove extending along the front-to-back direction, the clamping member cooperates with the dovetail groove to guide movement, and at this time, the gantry 2 is used to support the clamping member.

[0063] In another specific embodiment, each clamping member group 3 is configured with a limiting hole group located on the guide support member, the limiting hole group includes a plurality of limiting holes arranged at intervals along the front-back direction, and for any limiting hole group, two of the limiting holes are detachably installed with limiting members with one end inserted into the limiting hole, and the limiting members constitute the limiting portion. The limiting members are preferably limiting plates, and the limiting plates and the limiting holes are clearance-fitted or transition-fitted.

[0064] Compared with the solution of setting up the gantry 2, by installing two limit members in different limit holes, the front and rear span of the corresponding clamping member group 3 can be adjusted, so as to better adapt to the situation of increasing or decreasing the number of clamping members in the clamping member group 3.

[0065] In order to facilitate the increase or decrease of the number of clamping members in the clamping member group 3, as a specific implementation, for any clamping member group 3, the clamping members are divided into three types: a first end clamping member 31, an intermediate clamping member 32, and a second end clamping member 33. The first end clamping member 31 is only provided with the pressing portion, the intermediate clamping member 32 is provided with both the groove 9 and the pressing portion, and the third end clamping member is only provided with the groove 9. By increasing or decreasing the number of the intermediate clamping members 32, the number of clamping members in the clamping member group 3 can be conveniently increased or decreased.

[0066] In other specific embodiments, the number of clamping members may be four types, the first type is a first clamping member with a groove 9 provided on the rear side, the second type is a second clamping member with a pressing portion provided on both the front and rear sides, the third type is a third clamping member with a groove 9 provided on both the front and rear sides, and the fourth type is a fourth clamping member with a groove 9 provided on the front side. In this case, if you want to add or reduce clamping members, you must add or reduce the same number of second and third clamping members at the same time.

[0067] In the present invention, in order to more conveniently clamp the wire 600, as a specific embodiment, the wire clamping device 500 further includes a connecting rod 5, which is used to connect two clamping members in the adjacent clamping member group 3 that clamp the same wire 600 on the same side (front side or rear side). Figures 2~5 As shown, the two clamping members in the two clamping member groups 3 on the left side for clamping the same side (front side or rear side) of the same wire 600 are connected by a connecting rod 5, and the two clamping members in the two clamping member groups 3 on the right side for clamping the same side (front side or rear side) of the same wire 600 are also connected by a connecting rod 5.

[0068] Since the distance between the two clamping member groups 3 in the middle is relatively far, no connecting rod 5 is provided. The connecting rod 5 can be bonded and fixed to the clamping member, or both clamping members are provided with jacks, and the two ends of the connecting rod 5 are respectively inserted into the two jacks.

[0069] When assembling the wire clamping device 500 , firstly, the connecting rod 5 and the corresponding clamping member are connected to form a whole, then the whole is installed on the guide plate 12 , and finally, the gantry 2 is installed.

[0070] exist Figures 2~5 In the specific embodiment shown, when placing a conductor 600, if the connecting rod 5 is not provided, the four clamping members in the four clamping member groups 3 need to be moved four times respectively. After the connecting rod 5 is provided, only two connecting rods 5 need to be moved twice, which is convenient to operate.

[0071] Specific embodiments of the wire clamping device provided by the present invention: The wire clamping device in this embodiment is any one of the wire clamping devices in the specific embodiments of the wire conductivity measurement system of the present invention, and will not be described in detail here.
