[0031] Such as Figures 1-3A hot pressing device for a flexible cable reinforcing plate as shown includes a fixed bracket 100, a hot pressing assembly, and an anti-overflow glue assembly; the hot pressing assembly includes a first cylinder 200, an upper pressing block 201, and a lower pressing block 202. The first cylinder 200 is arranged on the fixed bracket 100, the upper pressing block 201 is arranged at the driving end of the first cylinder 200, the lower pressing block 202 is arranged on the fixed bracket 100, and heating elements 203 are arranged in both the upper pressing block 201 and the lower pressing block 202; the anti-overflow glue assembly includes a discharge tray 300, a driving mechanism, and a waste tray 301. The discharge tray 300, the driving mechanism, and the waste tray 301 are all arranged on the fixed bracket 100. The discharge tray 300 is filled with a separator film. The driving mechanism is used to drive the movement of the separator film. The separator film is used to wrap the material, and the waste tray 301 is used to recycle the used separator film. It should be noted that the heating element 203 is a heating tube. Through holes are provided on both the upper pressing block 201 and the lower pressing block 202. The heating tube extends into the through holes of the upper pressing block 201 and the lower pressing block 202 to heat the upper pressing block 201 and the lower pressing block 202. Since the upper pressing block 201 and the lower pressing block 202 cooperate to tightly press the reinforcing plate, the reinforcing plate will be heated by the upper pressing block 201 and the lower pressing block 202. The adhesive on the reinforcing plate is heated and melted, and then under the extrusion of the upper pressing block 201 and the lower pressing block 202, the reinforcing plate and the flexible cable are bonded more firmly. The separator film enters the hot pressing assembly under the action of the driving mechanism and covers the outer surfaces of the reinforcing plate and the flexible cable to prevent the overflowing glue from sticking to the surfaces of the reinforcing plate and the flexible cable, which is beneficial to improving the production quality of the flexible cable.

[0032] Please refer to Figure 1 and Figure 3 , in a possible implementation manner, the driving mechanism includes a first motor 400, a driving rubber roller 401, and a driven rubber roller 402. The first motor 400 is arranged on the fixed bracket 100. The driving end of the first motor 400 is connected to the driving rubber roller 401. The driving rubber roller 401 and the driven rubber roller 402 are rotatably arranged on the fixed bracket 100. The driven rubber roller 402 can be in contact with the driving rubber roller 401. The separator film passes between the driving rubber roller 401 and the driven rubber roller 402. It is easy to understand that the first motor 400 drives the driving rubber roller 401 to rotate. When the driven rubber roller 402 is in contact with the driving rubber roller 401, under the action of friction, the driving rubber roller 401 drives the driven rubber roller 402 to rotate, and the separator film passing between the driving rubber roller 401 and the driven rubber roller 402 is also driven to move forward. Moreover, the discharge tray 300 is rotatably arranged on the fixed bracket 100. When the separator film is driven, the discharge tray 300 rotates under the drive of the separator film, which is beneficial to improving the stability of the movement of the separator film.

[0033] Please refer to Figure 1, in a possible implementation, a second cylinder 403 is provided on the fixed bracket 100, and the driven rubber roller 402 is rotatably arranged at the driving end of the second cylinder 403. It is easy to understand that the second cylinder 403 is used to drive the driven rubber roller 402 to rise or fall. The staff needs to first raise the driven rubber roller 402, then pass the isolation film between the driving rubber roller 401 and the driven rubber roller 402, and then lower the driven rubber roller 402 so that the driving rubber roller 401 and the driven rubber roller 402 clamp the isolation film. In this way, when the driving rubber roller 401 rotates, it can drive the isolation film forward.

[0034] Please refer to Figure 1 and Figure 3 , in a possible implementation, the driving mechanism further includes a second motor 302. The second motor 302 is arranged on the fixed bracket 100, and the driving end of the second motor 302 is connected to the waste material tray 301. It should be noted that the discharge tray 300 and the waste material tray 301 are arranged in parallel, and the waste material tray 301 is arranged below the discharge tray 300. The second motor 302 is used to drive the waste material tray 301 to rotate, so that the waste material tray 301 can automatically collect the used isolation film. The isolation film is taken out from the discharge tray 300 under the action of the driving mechanism, then passes through the hot pressing assembly to protect the cable, and finally enters the waste material tray 301 under the drive of the waste material tray 301. The whole process is completed automatically, greatly improving the production efficiency of this device.

[0035] Please refer to Figure 1 , in a possible implementation, the anti-overflow glue assembly further includes a guide roller 303. The guide roller 303 is rotatably arranged on the fixed bracket 100. It is easy to understand that the guide roller 303 can guide the movement of the isolation film. Moreover, the guide roller 303 is rotatably arranged relative to the fixed bracket 100, which is beneficial to reducing the friction between the isolation film and the guide roller 303 and making the movement of the isolation film smoother.

[0036] Please refer to Figure 1 , in a possible implementation, the number of the guide rollers 303 is multiple, and the multiple guide rollers 303 are arranged in sequence along the moving path of the isolation film. It is easy to understand that the multiple guide rollers 303 are respectively arranged on the path where the isolation film enters the hot pressing assembly from the discharge tray 300 and the path from the hot pressing assembly to the waste material tray 301, so that the isolation film can be guided on the path from coming out of the discharge tray 300 to being recycled by the waste material tray 301, improving the stability of the whole process movement of the isolation film.

[0037] Please refer to Figure 2, in a possible implementation, it further includes a tensioning mechanism. The tensioning mechanism includes a guide rail 500, a slider 501, and a guide shaft 502. The guide rail 500 is disposed on the fixed bracket 100. The slider 501 is slidably connected to the guide rail 500. The guide shaft 502 is disposed on the slider 501 and contacts the isolation film. It is easy to understand that the staff can adjust the tension of the isolation film by adjusting the position of the guide shaft 502. Moreover, the guide rail 500 is disposed along the height direction of the fixed bracket 100, and the guide rail 500 can guide the slider 501, so that the movement of the guide shaft 502 is more stable.

[0038] Please refer to Figure 1 , in a possible implementation, a rubber pad 204 is provided at one end of the upper pressing block 201 close to the lower pressing block 202. It is easy to understand that the upper pressing block 201 moves downward under the drive of the first cylinder 200 and then abuts against the lower pressing block 202, so that the wire arrangement is fixed. The setting of the rubber pad 204 can protect the wire arrangement and prevent the wire arrangement from being damaged due to excessive pressure.

[0039] Please refer to Figure 1 and Figure 3 , in a possible implementation, a heat insulation plate 101 is provided on the fixed bracket 100, and the lower pressing block 202 is disposed on the heat insulation plate 101. It should be noted that a heat insulation plate 101 is also provided at the driving end of the first cylinder 200, and the upper pressing block 201 is also disposed on the heat insulation plate 101. The setting of the heat insulation plate 101 can block the heat from being transferred to the first cylinder 200 and the fixed bracket 100, reduce the heat dissipation efficiency of the upper pressing block 201 and the lower pressing block 202, so that the upper pressing block 201 and the lower pressing block 202 maintain their temperatures, which is beneficial to reducing the use cost of the device.

[0040] Please refer to Figure 1 , in a possible implementation, a temperature measuring element 205 is provided on the upper pressing block 201. It is easy to understand that the temperature measuring element 205 is a thermocouple. A thermocouple is a commonly used temperature measuring element in a temperature measuring instrument. The thermocouple can directly measure the temperature, convert the temperature signal into a thermoelectromotive force signal, and convert it into the temperature of the measured medium through an electrical instrument, so that the staff can intuitively see the real-time temperature of the upper pressing block 201 to ensure that the upper pressing block 201 is always within the optimal temperature range.

[0041] The above-mentioned implementation manners are only the preferred implementation manners of the present utility model, and cannot be used to limit the protection scope of the present utility model. Any non-substantial changes and substitutions made by those skilled in the art based on the present utility model belong to the protection scope required by the present utility model.
