[0029] Please refer to Figures 1 to 5 The utility model discloses a FPC pressure maintaining pressure head mechanism, including mounting plate 1 and a plurality of pressure maintaining components 2.
[0030] Each pressure maintaining component 2 includes fixing piece 21, pressure sensor 22 and pressure head 23, fixing piece 21 is located at mounting plate 1, pressure sensor 2 is connected with fixing piece 21.
[0031] Pressure head 23 includes metal sheet 231 and high temperature resistance piece 232, metal sheet 231 is connected with fixing piece 21 and slides, high temperature resistance piece 232 is connected with metal sheet 231 and protrudes the bottom surface of metal sheet 231, one pressure sensor 22 is used to sense the pressure value of the working state of one high temperature resistance piece 232.
[0032] Specifically, in the embodiment, the mounting plate 1 is installed with a plurality of pressure maintaining components 2, each pressure maintaining component 2 includes fixing piece 21, pressure sensor 22 and pressure head 23, the pressure head 23 includes the metal sheet 231 of hard metal processing and the high temperature resistance piece 232 of silica gel processing, the metal sheet 231 improves the pressure resistance of the pressure head 23, ensures the balance of pressure transmission, the high temperature resistance piece 232 improves the service life of the pressure head 23 under high temperature, the structure ensures the stability of pressure during the process that the external thermal sensitive film is pressed with the FPC plate under high temperature, improves the service life of the pressure head 23 simultaneously, reduces the use cost, and the working principle is as follows: after the external thermal sensitive film is attached with the external FPC plate, enters the pressure maintaining machine, the mounting plate 1 moves under the driving of external force, makes one pressure maintaining component 2 hold one attachment part, i.e. one pressure head 23 holds one attachment part, one pressure sensor 22 senses the pressure of one attachment part, ensures that the pressure of each attachment part is within the preset range, thereby improving the attachment quality.
[0033] By setting a plurality of pressure maintaining components 2, each pressure maintaining component 2 includes one pressure sensor 22 and one pressure head 23, so that the pressure of each external attachment part is controllable, improves the attachment quality stability, one pressure head 23 includes one metal sheet 231 and one high temperature resistance piece 232, improves the stability of the force of each attachment part and improves the service life of the pressure head 23, reduces the production cost.
[0034] The fixing member 21 includes an upper plate 211, a guide post 212, and a lower plate 213 connected in sequence. The upper plate 211 and the lower plate 213 are spaced apart. The pressure sensor 22 is fixedly connected to the upper plate 211, and the pressure head 23 is slidably connected to the lower plate 213 to ensure the stability of the vertical movement of the pressure head 23. The pressure sensor 22 is located between the upper plate 211 and the lower plate 213, which provides protection for the pressure sensor 22.
[0035] The pressing head 23 is also provided with a movable part 233. The movable part 233 is located between the upper plate 211 and the lower plate 213 and is set close to the lower plate 213. The movable part 233 is connected to the metal plate 231 and slides along the guide post 212. Preferably, the lower plate 213 is provided with a through hole. The movable part 233 includes an upper connector and a lower connector connected in sequence. The radial specification of the upper connector is larger than that of the lower connector. The lower connector passes through the through hole and connects to the metal plate 231, so that the pressing head 23 can move up and down along the guide post 212 and also abut against the external part to be bonded, thus meeting the usage requirements.
[0036] The pressure-holding assembly 2 further includes a buffer 24. The two ends of the buffer 24 are respectively connected to a pressure sensor 22 and a movable part 233.

The spring 241 is sleeved on the outside of the column 242. When the pressure-holding assembly 2 is pressed down as a whole, the pressure head 23 first abuts against the external part to be fitted. Under the action of the buffer 24, the pressure sensed by the pressure sensor 22 gradually increases until it reaches a constant value, thereby avoiding the generation of large pressure instantaneously, which would cause pressure sensing error in the pressure sensor 22, and further ensuring the accuracy of the pressure parameters.
[0037] The pressure sensor 22 includes a mounting base 221, a sensor 222, and a pressure plate 223. The mounting base 221 is fixedly connected to the upper plate 211.

The mounting base 221 is fixedly connected to the upper plate 211 and is used to mount the sensor 222. The pressure plate 223 has a blind hole that starts from the lower end face of the pressure plate 223. The column 242 of the buffer 24 protrudes into the blind hole and slides up and down along the blind hole, so that the pressure sensor 22 compresses the spring 24 during the downward pressing process, so that the pressure sensed by the pressure sensor 22 gradually increases from small to large.
[0038] The mounting plate 1 is provided with a plurality of upper through holes 11, and the fixing member 21 is provided with a lower through hole 201. One fixing member 21 is provided in one upper through hole 11, and the lower through hole 201 of one fixing member 21 coincides with the central axis of the upper through hole 11.
[0039] Each of the pressure heads 23 includes a micro-adjustment member 25, which passes through an upper through hole 11 and a lower through hole 201 and abuts against a pressure sensor 22. Preferably, the micro-adjustment member 25 is a micrometer, which is used to fine-tune the longitudinal spatial position of the pressure head 23 to ensure the accuracy of the pressure sensed by each pressure sensor 22 and further ensure the stability of the processing quality.
[0040] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of this utility model. The content of this specification should not be construed as a limitation of this utility model.
