[0002] A circuit board, also known as a circuit board, is an important electronic component, a support for electronic components, and a carrier for the electrical connection of electronic components. Because it is made using electronic printing technology, it is called a "printed" circuit board. Almost every electronic device, from electronic watches and calculators to computers, communication electronic equipment, and military weapon systems, as long as there are electronic components such as integrated circuits, must use a circuit board to make electrical interconnections between the various components. The circuit board consists of an insulating base plate, connecting wires, and pads for assembling and welding electronic components. It has the dual functions of a conductive line and an insulating base plate.

[0003] During the production process of circuit boards, it is inevitable to press and paste the substrate and copper foil. During the pressing and pasting process, if the pressure is insufficient, the copper foil and the substrate will not be firmly bonded or bubbles and gaps will appear. Excessive pressure may cause the copper foil to deform or even break. At the same time, abnormal temperature during pressing and pasting will also affect the performance of the adhesive, and thus affect the pressing and pasting quality between the substrate and the copper foil. In order to ensure the bonding quality between the substrate and the copper foil, it is necessary to accurately monitor and control the pressure and temperature during pasting. Utility Model Content

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] like Figures 1 to 7 As shown, the utility model provides a device 100 that can monitor the copper foil pasting pressure and temperature in real time, which includes a processing table 10, a pressing seat 20, a high-pressure cylinder 30, an air supply component 40, a pressure monitoring component 50, a temperature monitoring component 60 and a control system 70. The pressing seat 20 is arranged on the processing table 10, the high-pressure cylinder 30 is arranged above the pressing seat 20, the air supply component 40 is connected to the high-pressure cylinder 30 gas circuit, the pressure monitoring component 50 and the temperature monitoring component 60 are both arranged on the high-pressure cylinder 30, and the control system 70 is respectively connected to the high-pressure cylinder 30, the pressure monitoring component 50 and the temperature monitoring component 60. It can be understood that the utility model also includes a number of power supply, air supply devices and electrical connection structures, which are conventional contents in the technical field and are therefore not described in detail.

[0020] The pressing seat 20 includes a bearing base plate 21 and a sealing ring 22. The bearing base plate 21 is mounted on the processing table 10, and positioning posts 211 are provided at the four corners of the upper end of the bearing base plate 21. Positioning holes 221 are provided at the four corners of the sealing ring 22. The sealing ring 22 is arranged above the bearing base plate 21 and the positioning holes 221 are penetrated on the positioning posts 211. The positioning holes 221 pre-drilled on the substrate and the copper foil can be aligned with the positioning posts 211 on the bearing base plate 21 and penetrated to fit, thereby ensuring that the copper foil and the substrate will not be offset. The sealing ring 22 can fit on the upper surface of the copper foil, so that when the high-pressure cylinder 30 is subsequently pressed and pasted on the copper foil, gas leakage is avoided to affect the pasting quality.

[0021] The high-pressure gas cylinder 30 includes a sealed cylinder body 31 and a first telescopic gas rod 32. The sealed cylinder body 31 is provided with a pressing cavity 311 with a bottom opening. The sealed cylinder body 31 can be covered on the pressing seat 20. The first telescopic gas rod 32 is installed at the upper end of the sealed cylinder body 31 and can drive the sealed cylinder body 31 to move up and down. The first telescopic gas rod 32 can drive the sealed cylinder body 31 to descend and abut against the copper foil and the sealing ring 22, so that the pressing cavity 311 with a bottom opening is sealed and formed. After that, it is only necessary to inflate the pressing cavity 311, and the high-pressure gas inside it will exert force on the copper foil so that the substrate and the copper foil are pressed and pasted flatly and firmly.

[0022] The air supply assembly 40 includes an air supply pipeline 41, an exhaust pipeline 42, a high-pressure air pump (not shown) and an air source (not shown). The air supply pipeline 41 and the exhaust pipeline 42 are both installed on the sealed cylinder body 31 and communicated with the pressing cavity 311. The high-pressure air pump and the air source are connected to the other end of the air supply pipeline 41 in turn. The air supply pipeline 41 and the exhaust pipeline 42 are also provided with solenoid valves 411, and the two groups of solenoid valves 411 are respectively connected to the control system 70 by signal. The air supply assembly 40 provided with the solenoid valves 411 can freely control the air pressure in the pressing cavity 311 to adapt it to the optimal pressing force between the copper foil and the substrate.

[0023] The pressure monitoring assembly 50 includes a piston cylinder 51, a piston rod 52, a telescopic spring 53 and an elastic force monitoring sensor (not shown). The piston cylinder 51 is inserted into the sealed cylinder body 31 from top to bottom and is connected to the pressing cavity 311. The piston rod 52 is inserted into the piston cylinder 51. The telescopic spring 53 is sleeved on the piston rod 52. The elastic force monitoring sensor is pressed against the telescopic spring 53 and is connected to the control system 70 by signal. When the pressing cavity 311 in the sealed cylinder body 31 is filled with gas to form a high-pressure environment, the high-pressure gas will also push the piston rod 52 to rise along the piston cylinder 51, and the rising piston rod 52 will push the telescopic spring 53 to compress, so that the elastic force monitoring sensor detects the elastic force, and the pressure generated by the high-pressure gas on the copper foil surface can be obtained by measuring the elastic force of the spring.

[0024] The temperature monitoring assembly 60 includes an infrared temperature scanner 61 and a driving device (not shown). A scanning slide rail 312 is provided on the inner side of the sealed cylinder 31, and the infrared temperature scanner 61 is mounted on the scanning slide rail 312 and can slide horizontally. The driving device is installed in the pressing cavity 311 and is connected to the infrared temperature scanner 61. The driving device can drive the infrared temperature scanner 61 to scan the surface of the copper foil back and forth, thereby monitoring the temperature of the copper foil surface in real time and reporting the temperature parameters to the control system 70 for display.

[0025] The device 100 capable of real-time monitoring of copper foil pasting pressure and temperature further comprises a temperature control assembly 80, and the temperature control assembly 80 comprises a second telescopic gas rod 81, a mounting plate 82 and a plurality of heating sheets 83. The second telescopic gas rod 81 is mounted on the top of the pressing cavity 311, the mounting plate 82 is mounted on the lower end of the second telescopic gas rod 81 and can be moved up and down, and the plurality of heating sheets 83 are all attached to the bottom of the mounting plate 82 and are respectively connected to the control system 70 by signal.

[0026] The control system 70 can compare the surface temperature of the copper foil monitored by the infrared temperature scanner 61 with the preset temperature parameters to obtain the temperature value that needs to be adjusted. Then the control system 70 can control the second telescopic gas rod 81 to rise or fall appropriately to adjust the distance between the heating plate 83 and the copper foil, and control each heating plate 83 to generate heat so that the copper foil, the substrate and the adhesive between the two are at the optimal temperature. Each heating plate 83 can be controlled and fine-tuned to emit different heat to ensure that the center and edge of the copper foil, the substrate and the adhesive are at the same temperature level.

[0027] In summary, the beneficial effects of the device 100 of the utility model that can monitor the copper foil pasting pressure and temperature in real time are: by designing a piston-type pressure monitoring component 50 in conjunction with a pneumatic pressing and pasting structure, the pressure between the copper foil and the substrate can be monitored in real time during the pressing and pasting process, thereby ensuring the quality of the pasting between the copper foil and the substrate; the positioning column 211 and the sealing ring 22 structure are designed on the pressing seat 20, so that the copper foil and the substrate will not be offset in the upper and lower alignment, and at the same time, the process of gas extrusion and bonding is more reliable; the air supply component 40 is designed with an electromagnetic valve 411 to cooperate with the automatic control of the control system 70, so that the force applied to the copper foil during pasting is more accurate and appropriate; the temperature monitoring component 60 can scan and monitor the temperature parameters during the pasting of the copper foil in real time, and cooperate with the temperature control component 80 to accurately control the ambient temperature of the copper foil pasting, thereby ensuring that the effect of the adhesive remains stable and reliable; the utility model is highly practical and has a strong promotional significance.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
