Description

Technical Field

[0001] This utility model relates to the field of thickness detection technology, and more specifically, to a copper flat wire thickness detection device. Background Technology

[0002] Copper flat wire is a conductive material widely used in electrical equipment, power transmission, and electronics manufacturing. Made of high-purity copper, it possesses excellent electrical conductivity, thermal conductivity, and mechanical strength. Copper flat wire is commonly used in motor windings, transformers, busbars, and other applications requiring high-efficiency conductivity.

[0003] In the production process of copper flat wire, ensuring uniform thickness is crucial for guaranteeing the quality and performance of the final product. Existing technologies for inspecting copper flat wire typically only monitor the overall thickness or inspect a single point. For example, a testing device for producing small flat wires for automotive drive motors, published in CN218155882U, uses two relatively long diameter measuring rollers that press entirely onto the flat wire. Since the horizontal radial thickness of the flat wire may vary, this method cannot achieve multi-point testing. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a thickness detection device that can perform multi-point detection of copper flat wire.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A copper flat wire thickness detection device, comprising:

[0007] Fixture;

[0008] The support roller is rotatably mounted on the fixed frame and is used to support the bottom of the copper flat wire;

[0009] The thickness measuring mechanism includes a pressure roller that is vertically and elastically movable above the support roller, and a displacement sensor whose sensing end is connected to the pressure roller. The displacement sensor is used to detect the displacement distance of the pressure roller.

[0010] A moving mechanism is mounted on the fixed frame. The power output end of the moving mechanism is connected to the thickness measuring mechanism and is used to drive the pressure roller to move horizontally and radially along the copper flat wire.

[0011] Preferably, the pressure roller is provided with a sleeve connected to the central shaft of the pressure roller, and a vertically arranged telescopic rod is installed on the sleeve, and a spring is sleeved on the telescopic rod.

[0012] Preferably, the moving mechanism includes a moving block that can be moved horizontally along the radial direction of the copper flat wire, and a drive assembly whose power output end is connected to the moving block to drive the moving block to move; the end of the telescopic rod away from the pressure roller is connected to the moving block.

[0013] Preferably, the fixing frame is provided with at least two spaced guide rods, and the moving block is guided and sleeved on the guide rods.

[0014] Preferably, the top of the fixing frame is provided with a connecting plate; the driving assembly includes a positioning member that is radially movably disposed on the connecting plate along the copper flat wire, the bottom of the positioning member being connected to the moving block; and further includes a locking member disposed on the positioning member to lock the position of the positioning member.

[0015] Preferably, the fixing frame includes two horizontally spaced fixing plates, and the connecting plate is connected between the fixing plates.

[0016] Preferably, the copper flat wire thickness detection device further includes a substrate, and the fixing frame is disposed on the substrate.

[0017] Preferably, the copper flat wire thickness detection device further includes a set of limiting rollers disposed on the substrate and located on both sides of the fixing frame; the set of limiting rollers has two limiting rollers disposed vertically, and the copper flat wire passes through the two limiting rollers to make the copper flat wire horizontally transported.

[0018] Compared with the prior art, the advantages of this utility model are as follows:

[0019] During testing, the copper flat wire is placed on the carrying roller, and then the pressure roller is elastically pressed onto the top surface of the copper flat wire. The thickness of the copper flat wire is obtained by detecting the displacement change of the pressure roller through a displacement sensor. With the help of the moving mechanism, the thickness measuring mechanism can be moved along the horizontal radial direction of the flat wire, which in turn causes the pressure roller to move along the horizontal radial direction of the copper flat wire to detect the thickness at different points in the horizontal radial direction of the copper flat wire, realizing multi-point detection and improving the comprehensiveness of the detection.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] A copper flat wire 7 thickness detection device includes: a fixed frame 1; a support roller 2, rotatably mounted on the fixed frame 1, for supporting the bottom of the copper flat wire 7; a thickness measuring mechanism 3, including a pressure roller 31 vertically and elastically movable above the support roller 2, and a displacement sensor 32 with its sensing end connected to the pressure roller 31, the displacement sensor 32 being used to detect the displacement distance of the pressure roller 31; and a moving mechanism 4, mounted on the fixed frame 1, the power output end of the moving mechanism 4 being connected to the thickness measuring mechanism 3, for driving the pressure roller 31 to move horizontally radially along the copper flat wire 7.

[0026] Understandably, the mounting bracket 1 is a component used to install the thickness measuring mechanism 3 and the moving mechanism 4. For example, it can be a structure of two horizontally spaced flat plates, or a structure of two horizontally spaced bent plates, etc., but is not limited to these. The thickness measuring mechanism 3 is a component used to detect the thickness of the copper flat wire 7. Here, a contact-type pressure roller 31 combined with a position sensor is used. The elastic movement of the pressure roller 31 can be a pneumatic elastic telescopic rod 34 structure or a spring-type telescopic rod 34 structure, etc., but is not limited to these. The position sensor can be a laser position sensor, or a magnetostrictive displacement sensor 32, etc. The moving mechanism 4 can be an automatically driven structure, such as using an electric push rod or a screw drive, or it can be a manually driven structure, such as using a slide rail guide or a shaft hole guide structure, with a slider for manual pushing.

[0027] During testing, the copper flat wire 7 is placed on the support roller 2, and then the pressure roller 31 is elastically pressed against the top surface of the copper flat wire 7. Depending on the position of the copper flat wire 7 to be tested, the thickness measuring mechanism 3 is moved by the moving mechanism 4, which in turn moves the pressure roller 31 horizontally and radially along the copper flat wire 7 to the required testing position. Finally, the thickness of the copper flat wire 7 is determined by detecting the displacement change of the pressure roller 31 using the displacement sensor 32. Here, when the pressure roller 31 is pressing on the support roller 2, the thickness detected by the displacement sensor 32 is zero. When the pressure roller 31 is pressing on the copper flat wire 7, the upward movement of the displacement sensor 32 is the thickness of the copper flat wire 7.

[0028] In some embodiments, the pressure roller 31 is provided with a housing 33 connected to the central axis of the pressure roller 31, and a vertically arranged telescopic rod 34 is installed on the housing 33. A spring 35 is sleeved on the telescopic rod 34. Further, the moving mechanism 4 includes a moving block 41 that can be moved horizontally along the radial direction of the copper flat wire 7, and a drive assembly whose power output end is connected to the moving block 41 to drive the moving block 41 to move; one end of the telescopic rod 34 away from the pressure roller 31 is connected to the moving block 41. Here, the two ends of the spring 35 abut against the housing 33 and the moving block 41, so that the extension and retraction of the telescopic rod 34 can be elastically controlled. The moving block 41 can be configured with a shaft hole guide structure, or a sliding structure with a groove and a slider, etc., but is not limited to these. In this way, the drive assembly can drive the moving block 41 to move horizontally, thereby driving the pressure roller 31 to move, to change the detection points at different positions of the copper flat wire 7.

[0029] Furthermore, the fixing frame 1 is provided with at least two spaced guide rods 42, and the moving block 41 is guided and sleeved on the guide rods 42. A shaft hole guiding structure is used here. Furthermore, a connecting plate 12 is provided at the top of the fixing frame 1; the driving assembly includes a positioning member 43 movably disposed radially along the copper flat wire 7 on the connecting plate 12, the bottom of the positioning member 43 being connected to the moving block 41; it also includes a locking member 44 disposed on the positioning member 43 to lock its position. A manual driving structure is used here. The movement of the positioning member 43 can be achieved by opening a groove on the connecting plate 12, allowing the positioning member 43 to slide into the groove for a sliding fit; alternatively, a slide rail can be provided on the connecting plate 12, allowing the positioning member 43 to slide on the slide rail, etc. The locking member 44 is a component used to lock the position of the positioning member 43. For example, several positioning holes can be opened on the connecting plate 12, and bolts or positioning pins can be inserted into the positioning holes for position locking, etc., but not limited to these methods.

[0030] In some embodiments, the fixing frame 1 includes two horizontally spaced fixing plates 11, and the connecting plate 12 is connected between the fixing plates 11. Thus, both ends of the bearing roller 2 and both ends of the guide rod 42 can be connected to the fixing plates 11 respectively, resulting in a more stable structure.

[0031] In some embodiments, the copper flat wire 7 thickness detection device further includes a substrate 6, and the fixing frame 1 is disposed on the substrate 6. Here, the substrate 6 is not only an independent plate, but can also be a part of the body of other equipment. Further, the copper flat wire 7 thickness detection device also includes a limiting roller group 5 disposed on the substrate 6 and located on both sides of the fixing frame 1; the limiting roller group 5 has two limiting rollers 51 arranged vertically, and the copper flat wire 7 passes between the two limiting rollers 51, allowing the copper flat wire 7 to be transported horizontally. Here, the upper and lower limiting rollers 51 can limit the copper flat wire 7 vertically, ensuring the horizontal position of the copper flat wire 7 and guaranteeing the stability of the measurement.

[0032] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
