Description

TECHNICAL FIELD

[0001] The utility model relates to FPC laminating equipment technical field especially relates to a kind of FPC laminating processing platform temperature detection device. BACKGROUND

[0002] With the rapid development of electronic industry, flexible printed circuit board (FPC) is increasingly widely used in the field of smart phones, tablet computers, wearable devices etc. FPC pressing is an indispensable link in production process, which is directly related to product quality and production efficiency. The traditional FPC temperature is collected by thermocouple of the equipment, which not only increases the production cost, but also limits the flexibility and versatility of the equipment. Therefore, it is particularly important to design a device suitable for rapid temperature detection.

[0003] The prior art such as Chinese patent No. CN209982842U is a kind of rapid laminator, more specifically, it relates to a kind of rapid laminator for FPC. The technical solution points are: including rack, at least two pressing cavities are arranged on the rack, pressing assembly is arranged in the pressing cavity, lifting device is arranged below the pressing assembly, the pressing assembly includes upper laminating plate and a plurality of lower laminating plates located below the upper laminating plate, the opposite two cavity walls of the pressing cavity are provided with a sliding groove, the lower laminating plate is provided with a sliding block on both sides, the cavity wall of the pressing cavity is provided with transmission assembly, the transmission assembly includes gear and rack connected with the gear, the side wall of the lower laminating plate is provided with a connecting plate, the rack is fixedly arranged on the bottom surface of the connecting plate, and the rack is provided with a driving assembly.

[0004] The above-mentioned patent lacks temperature detection device. Since FPC (flexible circuit board) is relatively soft, it is easy to absorb moisture in the air during transportation and storage, so it is necessary to use a pressing machine for pre-baking treatment before pressing to slowly force the moisture out. Otherwise, under the impact of rapid pressing high temperature, the water absorbed by FPC quickly vaporizes into water vapor and protrudes from FPC, which can cause FPC delamination, blistering and other defects. In order to ensure the baking effect, it is necessary to test the actual temperature in the pressing machine. Although the current equipment is equipped with a single temperature measuring wire for point detection test, it cannot detect all temperature control points on the table top, cannot guarantee the stability and uniformity of temperature, and has quality risks. In the existing FPC pressing technology, in order to ensure the uniformity and stability of temperature in the pressing process, the method commonly used includes temperature measurement by thermocouple of the equipment. However, this temperature measurement method has certain limitations. UTILITY MODEL CONTENTS

[0026] The technical scheme of the utility model is further illustrated in the embodiment.

[0027] As Figures 1-5The utility model provides a kind of FPC laminating processing platform temperature detection device shown, including temperature measuring intermediate layer 1, heat insulation top layer 2 and heat insulation bottom layer 3, temperature measuring intermediate layer 1 is between heat insulation top layer 2 and heat insulation bottom layer 3, heat insulation top layer 2 and heat insulation bottom layer 3 are made of heat insulation material. At least three groups of temperature measuring components 4 and the monitoring component for showing the temperature of temperature measuring component 4 are provided on temperature measuring intermediate layer 1, each group of temperature measuring component 4 includes at least two temperature sensors 401, and temperature sensor 401 is connected with monitoring component;Several groups of temperature measuring components 4 are respectively spaced apart on the top, middle and bottom of temperature measuring intermediate layer 1, several temperature sensing points 201 are opened on heat insulation top layer 2, temperature sensing point 201 corresponds with the position of temperature sensor 401, and the top, middle and bottom of temperature measuring intermediate layer 1 are respectively provided with at least two temperature sensors 401, which can effectively improve the accuracy and uniformity of temperature detection, avoid product quality problems caused by local temperature difference, and also can be transformed according to actual demand, and temperature sensing is carried out at multiple positions.

[0028] Temperature measuring intermediate layer 1 includes green silica gel, which has good high-temperature resistance and thermal conductivity, and can ensure the normal work of temperature sensor 401. Temperature sensor 401 can adopt two types of thermocouple or thermal resistance, and the advantages of thermocouple are fast response speed and suitable for dynamic temperature change detection. Thermal resistance has high measurement accuracy and is suitable for static temperature detection. The monitoring component includes a display screen 402 for displaying the temperature detected by the temperature sensor 401 and a connecting line 403, one end of the connecting line 403 is connected with the display screen 402, and the other end of the connecting line 403 is connected with several temperature sensors 401 respectively. The display screen 402 is located on the outside of the temperature measuring intermediate layer 1, so that the operator can directly see the actual temperature of each temperature sensing point 201 and adjust the pressing parameters in time to ensure the pressing quality.

[0029] Heat insulation top layer 2 and heat insulation bottom layer 3 adopt red silica gel, which has excellent heat insulation performance and can effectively prevent external heat conduction to temperature measuring intermediate layer 1, affecting the accuracy of temperature detection. The thickness of heat insulation top layer 2 and heat insulation bottom layer 3 is between 0.6-1mm, which can ensure sufficient heat insulation effect without increasing excessive weight and volume, and is convenient for integration into existing pressing equipment. The thickness of temperature measuring intermediate layer 1 is between 0.8-1.3mm, which can accommodate temperature sensor 401 and other components without affecting the sensitivity of temperature transmission due to excessive thickness.

[0030] The intermediate temperature sensing layer 1, the top insulation layer 2, and the bottom insulation layer 3 are filled with fiberglass fabric. This material has good insulation and mechanical strength, which can enhance the structural stability of the entire device and prevent deformation or damage in high-temperature environments. The surface layers of the intermediate temperature sensing layer 1, the top insulation layer 2, and the bottom insulation layer 3 are filled with nano-thermal conductive materials to improve the thermal conductivity of the surface layer, allowing the temperature to be transferred more evenly to the temperature sensor 401 and improving the detection accuracy.

[0031] The surfaces of the top insulation layer 2 and the bottom insulation layer 3 are flat, which reduces the thermal resistance at the contact surface and ensures the accuracy of temperature detection. The top insulation layer 2 and the bottom insulation layer 3 have the same thickness, which ensures that the insulation effect on both sides is consistent and avoids temperature deviation caused by uneven thickness.

[0032] The intermediate temperature measurement layer 1 has several guide slots 101 for mounting the wires of the temperature sensor 401. This facilitates the installation and maintenance of the temperature sensor 401, reduces wiring complexity, and improves system reliability and maintenance convenience. The guide slots 101 can have a rectangular or circular cross-section, and the appropriate shape and size can be selected according to actual needs.

[0033] The depth and width of the guide groove 101 can be adjusted according to the size of the temperature sensor 401. The depth of the guide groove 101 is slightly larger than the diameter of the wire of the temperature sensor 401 to ensure that the wire can be smoothly embedded and fixed. The length of the guide groove 101 can be set according to the size of the temperature measurement intermediate layer 1 to cover the entire detection area.

[0034] The monitoring component includes a display screen 402 for displaying the temperature detected by the temperature sensor 401 and a connecting line 403. One end of the connecting line 403 is connected to the display screen 402, and the other end of the connecting line 403 is connected to several temperature sensors 401 respectively. The display screen 402 is located on the outside of the temperature measurement intermediate layer 1.

[0035] The display screen 402 can be either an LCD screen or an LED screen. LCD screens offer lower power consumption and higher resolution, making them suitable for continuous operation over extended periods. LED screens, on the other hand, provide higher brightness and contrast, making them suitable for outdoor or brightly lit environments. The display screen 402 can display real-time temperature data, historical temperature curves, alarm information, and other content, allowing operators to comprehensively understand temperature changes during the pressing process.

[0036] The top heat insulation layer 2 and the bottom heat insulation layer 3 completely cover both sides of the temperature measuring intermediate layer 1 to prevent high-temperature processing from damaging the temperature measuring intermediate layer 1. At the same time, the top heat insulation layer 2 and the bottom heat insulation layer 3 have the same thickness to prevent the device from affecting the FPC lamination process.
