Description

Technical Field

[0001] The utility model relates to the technical field of electronic product manufacturing, in particular to an online fully automatic measuring device for thermal conduction gaps. Background Technique

[0002] With the improvement of the computing power and the reduction of the physical size of electronic devices in weaponry, the temperature control of chips, as one of their components, has become one of the key elements that need to be considered in product design. The increase in temperature will lead to problems such as a slowdown in the operating speed of the device and an increase in the probability of chip failures, and even phenomena such as device burnout that directly threaten the design functions of the product. Therefore, in order to effectively control the temperature of chips and PCB boards, it is necessary to use thermal conduction gap filling materials to achieve the heat transfer of heat dissipation devices. In the actual production process, due to reasons such as chip manufacturing errors, heat sink processing errors, and chip mounting errors, there are certain deviations between the actual size and the designed size between the chips and the heat sinks in electronic products, resulting in a large deviation between the designed thickness value of the thermal conduction pad and the actual thickness requirement value. Therefore, it is necessary to adapt according to the actual required thickness value of the thermal conduction pad at the product assembly site. The traditional adaptation method is to add the measured data using a vernier caliper according to the designed gap value, appropriately fill the thermal conduction pad with the corresponding thickness, then apply a display agent on the top of the device, open it after pressing the heat sink and the PCB board together, and finally judge the pressing situation according to the display of the display agent. This traditional method has many problems, such as poor measurement accuracy, complex measurement process, low efficiency, and high requirements for personnel capabilities. At the same time, if the measurement of the thermal conduction gap value is inaccurate, there will be situations of failure to press or over-press during pressing, resulting in poor heat dissipation of the product or even damage to the device or PCB, causing significant economic losses. Therefore, in order to solve the problem of difficult measurement and confirmation of thermal conduction gaps, improve the sticking efficiency of thermal conduction pads and product quality, and reduce the workload of workers, it is very necessary to design a fully automatic measuring device for thermal conduction gaps.

[0025] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0026] An online fully automated thermal gap measurement device, including a frame 13, a measurement substrate 2, and an internal mechanism. A swing door 1 is provided on the front surface of the frame 13. An inner cavity is provided at the swing door 1 of the frame 13. A measurement substrate 2 is provided at a horizontal plane of the inner cavity of the frame 13. An internal mechanism is fixedly connected to the top of the measurement substrate 2;

[0027] The internal mechanism includes an X module 4, a Y module 8, and a clamping mechanism 10. I-shaped connecting rods 3 are vertically arranged upward at the four top corners of the top of the measurement substrate 2. An X module 4 is provided at the top of two I-shaped connecting rods 3 on the same side. An X module fixing seat 9 is slidably connected to the surfaces of the two X modules 4. The two X module fixing seats 9 are respectively connected to both sides of the Y module 8. A Y module fixing seat 11 is slidably connected to the surface of the Y module 8. A 3D camera 5 is fixedly connected to the front surface of the Y module fixing seat 11;

[0028] Conveyor rails 6 are provided on both sides of the top of the measurement substrate 2 and inside the four I-shaped connecting rods 3. A material positioning device 7 is slidably connected to the surface of the conveyor rails 6.

[0029] Specifically, the device frame 13 and the measurement substrate 2 provide a stable measurement platform for the entire measurement. The conveyor rails 6 realize the automatic transmission and positioning of materials. The material positioning device 7 is used for the placement and precise positioning of materials. The 3D camera 5 is mainly used to automatically identify the three-dimensional images of PCB boards or pressing plates. The X module 4 and the Y module 8 drive the 3D camera 5 to take pictures of the PCB board or the pressing board on the material positioning device 7. Therefore, the 3D camera 5 can move within a certain range in the XY plane to take pictures of large-size products at one time.

[0030] Further, a control panel 12 is provided at the front end of one side of the frame 13. The control panel 12 can control the entire device.

[0031] Further, the conveyor rails 6 and the material positioning device 7 are connected to the production line for full-automatic measurement.

[0032] Furthermore, grating scales are installed on both sides of the conveying track 6 to accurately position the product in real time.

[0033] Furthermore, a clamping mechanism 10 is provided on the outer side of the top of one of the X modules 4. The clamping mechanism 10 is connected to a clamping plate 14 in a clamping manner. The front surface of the clamping plate 14 is connected to one side of the Y module 8. By providing the clamping mechanism 10 and connecting the clamping plate 14 to the inside of the clamping mechanism 10, the present utility model connects one end of the Y module 8 through the clamping plate 14. On the basis of not affecting the movement of the Y module 8 by the X module 4, a certain limit is imposed on the Y module 8 to prevent the photos taken by the 3D camera 5 from being unsatisfactory due to vibration during operation, which has a certain impact on the measurement of the heat conduction gap.

[0034] Working principle: First, fix the PCB board to be measured on the material tray, and convey the tray to the conveying track 6 of this equipment through the conveying line. The conveying track 6 automatically conveys the tray to the material positioning device 7 to accurately position the material. Then, the operator sets the HMI to call the database through the control screen 12 on the frame 13, and calls out the model batch of the PCB board for which the heat conduction gap needs to be measured currently, the positions of the chips / studs where the thermal pads need to be pasted, the sizes of the chips / studs, and the thickness values of the thermal pads that need to be pasted for each chip / stud. Then, after starting the operation of the X module 4 and the Y module 8 by pressing the buttons at the bottom of the control screen 12, the X module 4 and the Y module 8 will drive the 3D camera 5 to take pictures and perform three-dimensional imaging directly above the PCB board on the material positioning device 7, automatically identify the height values and positions of the chips / studs where the thermal pads need to be pasted and automatically match them with the data of the PCB board of this model batch. After successful matching, the conveying track 6 will push out the PCB board together with the tray and convey it to the production line assembly workstation. Then, the pressing plate is measured and matched in the same way. After the measurement is completed, the equipment can give the accurate values of each heat conduction gap and the recommended thickness values of the thermal pads.

[0035] Compared with the prior art, the present invention uses an online conveying track method for material transmission. Compared with the traditional material conveying method, it has the advantages of simple operation and high efficiency, and can be perfectly connected with the production line to realize automatic measurement and efficient transmission of data.
