[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for the purpose of explaining the present invention and are not intended to limit the present invention. That is, the embodiments described herein are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and illustrated in the drawings herein can be arranged and designed in a variety of different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-4As shown, in the embodiment of the present invention, an automatic measurement and control device for enameled wire coating includes a paint rack 1, wherein the paint rack 1 is provided with a line channel (not shown in the figure), the paint rack 1 is a box with one side open, and a detection device is provided next to the paint rack 1, and the detection device is provided on the open side of the paint rack 1, and the outlet end of the line channel of the paint rack 1 is connected to the paint touch-up chamber 2, and the paint touch-up chamber 2 is provided with an enameled wire channel 201, a paint touch-up channel 202 and a paint touch-up cavity 203, one end of the enameled wire channel 201 is connected to the line channel inside the paint rack 1, and the other end is connected to the outside of the paint touch-up chamber 2, the middle part of the enameled wire channel 201 is connected to the paint touch-up cavity 203, one end of the paint touch-up channel 202 is connected to the paint touch-up cavity 203, and the other end is connected to an electric valve 204, the electric valve 204 is connected to the paint supply device, and the detection device is connected to the electric Valve 204 is controlled by an external control system; when working, the copper conductor enters the internal line channel of the painting rack 1 to be wrapped with paint liquid, and the painted copper conductor enters the enameled wire channel 201 in the paint touch-up chamber 2 from the line channel, and enters the paint touch-up chamber 203 from the connected enameled wire channel 201, and finally leaves from the outlet end of the enameled wire channel 201. The detection device is aimed at the painted copper conductor in the line channel of the painting rack 1. When the detection device detects that the paint on the copper conductor is missing or insufficient, the electric valve 204 will automatically open under the control of the control system, and the paint supply device will introduce the paint liquid from the paint touch-up channel 202 into the paint touch-up chamber 203. The copper conductor with insufficient paint liquid can be replenished with paint liquid when passing through the paint touch-up chamber 203; this design can monitor the paint coating condition of the enameled wire in real time, and automatically perform paint touch-up when the paint liquid is insufficient, thereby ensuring the quality of the enameled wire product.

[0025] In one embodiment, see Figure 1 As shown, the painting rack 1 is equipped with an audible and visual alarm 7, which is linked to the detection device through an external control system. When the detection device frequently detects that the paint coating on the enameled copper conductor is insufficient and exceeds the set value within a certain period of time, the audible and visual alarm 7 will be turned on under the control of the control system to remind the staff that there is a fault in the production of the enameled wire and the production should be stopped for investigation to avoid affecting the production quality of the enameled wire products.

[0026] In one embodiment, see Figure 1As shown, the detection device includes a support frame 3, a telescopic mechanism 4 and a color sensor 6. The telescopic mechanism 4 is fixedly installed on the top of the support frame 3. The end of the telescopic mechanism 4 away from the support frame 3 is connected to the clamping mechanism 5. The color sensor 6 is installed on the support frame 3. The sensor probe 601 associated with the color sensor 6 passes through the clamping mechanism 5 and is clamped and fastened by the clamping mechanism 5. The sensor probe 601 is aligned with the paint-coated copper conductor in the line channel of the paint rack 1. The color sensor 6 is associated with the electric valve 204 and the sound and light alarm 7 through an external control system. The normal color range value of the color sensor 6 can be set according to the color of the paint liquid. During normal production, the copper wire is wrapped in the paint liquid and passes through the line channel. When the copper wire passes through the channel, the sensor probe 601 detects the color of the paint liquid and no signal is output. When the paint on the surface of the copper wire is insufficient or missing, the color detected by the sensor probe 601 exceeds the set color range, and the output signal opens the electric valve 204 for automatic paint touch-up. When the color detected by the sensor probe 601 is within the set color range, the electric valve 204 will be closed and no longer supply paint. The paint liquid in the paint touch-up chamber 203 will flow into the paint rack 1 along the enameled wire channel 201 to avoid the paint liquid from accumulating in the paint touch-up chamber 203. It should be noted that when the sensor probe 601 frequently outputs paint touch-up signals within a certain period of time and exceeds the set value, the sound and light alarm 7 will start to warn, reminding the operator to check for equipment failure.

[0027] In one embodiment, see Figure 2 As shown, the clamping mechanism 5 includes a first clamping block 501 and a second clamping block 502 that are symmetrical to each other, and the second clamping block 502 is connected to the telescopic mechanism 4 on a side away from the first clamping block 501. Locking parts 503 are provided on both sides of the first clamping block 501 and the second clamping block 502. A threaded rod 504 is provided on the locking part 503 of the second clamping block 502, and the threaded rod 504 passes through the locking part 503 of the first clamping block 501. A limiting nut 506 is provided on one end of the threaded rod 504 away from the second clamping block 502, and the sensor probe 601 is placed between the first clamping block 501 and the second clamping block 502. By locking the limiting nut 506, the first clamping block 501 and the second clamping block 502 can clamp the sensor probe 601. This design can firmly clamp the sensor probe 601 and prevent the detection effect from being affected by the shaking of the sensor probe 601.

[0028] In one embodiment, see Figure 2 As shown, the first clamping block 501 and the second clamping block 502 are designed to have a curved surface close to the axis of symmetry to match the shape of the sensor probe 601, and the curved surface is made of soft material to reduce damage to the sensor probe 601 caused by clamping while ensuring stable clamping.

[0029] In one embodiment, see Figure 2As shown, the threaded rod 504 is provided with a locking spring 505, and the locking spring 505 is arranged between the locking portion 503 of the first clamping block 501 and the limiting nut 506. The first clamping block 501 and the second clamping block 502 will be pressed against each other under the action of the locking spring 505, thereby clamping the sensor probe 601 placed between the first clamping block 501 and the second clamping block 502. The clamping force can be adjusted by turning the limiting nut 506. The first clamping block 501 is provided with a lifting rod 507 for easy lifting. The first clamping block 501 can be separated from the second clamping block 502 by lifting the first clamping block 501, so that the sensor probe 601 can be clamped or removed on the clamping mechanism 5 more easily, and disassembly and assembly are convenient.

[0030] In one embodiment, see Figure 3 As shown, the telescopic mechanism 4 includes a fixed block 401 and a movable rod 402. A cavity is opened inside the fixed block 401. One end of the movable rod 402 is connected to the second clamping block 502, and the other end extends into the internal cavity of the fixed block 401. The movable rod 402 is axially arranged with several spring buttons 403. The spring buttons 403 have built-in springs. The fixed block 401 is provided with a positioning hole 405 that cooperates with the spring button 403. When the spring button 403 is pressed, the movable rod 402 can slide and retract in the fixed block 401, thereby driving the connected clamping mechanism 5 to retract and retract. When the spring button 403 coincides with the positioning hole 405, the spring button 403 is released. The spring button 403 will pop out under the action of the built-in spring and be stuck in the positioning hole 405 for limiting. The height of the clamping mechanism 5 can be adjusted by the telescopic mechanism 4, so as to flexibly adjust the detection position of the sensor probe 601 on the enameled copper conductor according to actual needs.

[0031] In one embodiment, see Figure 3 As shown, a telescopic spring 404 is provided in the cavity of the fixed block 401, one end of the telescopic spring 404 is connected to the inner wall of the fixed block 401, and the other end is connected to the movable rod 402. The telescopic spring 404 connects the movable rod 402 and the inner wall of the fixed block 401, which can prevent the movable rod 402 from being pulled out of the fixed block 401 during telescopic adjustment, affecting work efficiency.
