The force sensor is one of the most important components within the touch module; its assembly precision directly affects the sensitivity and accuracy of the touch module. A common assembly method involves attaching the force sensor to the semi-finished touch module.

[0003] Currently, the force sensor assembly technology commonly used in the production of laptop touch modules employs a traditional shape positioning method. This method suffers from low efficiency and low yield of assembled products due to the influence of product shape tolerances.

[0046] In summary, during the operation of this invention, firstly, when the Y-axis moving module 4 moves the material handling device 6 away from the first positioning base mold 2, the semi-finished touch module 10 is manually placed onto the first positioning base mold 2. The touch module 10 is positioned and clamped by the positioning fixture 2K. Then, when the Y-axis moving module 4 moves the material handling device 6 away from the second positioning base mold 3, the force sensor 100 is placed onto the second positioning base mold 3. Furthermore, after the touch module 10 is placed onto the first positioning base mold 2 and before the material handling device 6 moves above the first positioning base mold 3, the first light source module 9 moves the supplementary light lamp 94 above the first positioning base mold 3 for supplementary lighting. The camera module 8 illuminates the first positioning base mold 3 through the first supplementary light lamp 94. The touch module 10 on module 2 takes a picture to identify the position; further, the Y-axis moving module 4 moves the picking module 6 above the second positioning bottom mold 3, and the Z-axis moving module 5 lowers the picking module 6 to contact the force sensor 100, thereby grasping the force sensor 100. Then, the Y-axis moving module 4 and the Z-axis moving module 5 cooperate to move the picking device 6 above the first positioning bottom mold 2. At this time, the first light source module 9 has moved away from above the first positioning bottom mold 2; further, the second light source module 90 moves the second supplementary light 903 above the picking device 6 to provide supplementary lighting, and the camera module 8 takes a picture of the force sensor 100 through the second supplementary light 903, thereby recognizing the position of the force sensor 100. The position information is compared with the previously acquired position information of the touch module 10, and the first positioning bottom mold 2 adjusts the angle and position of the touch module 10 so that the force sensor 100 is positioned above the corresponding mating position of the touch module 10 in the XY plane. Further, the lifting device 76 in the hot-pressing module 7 lowers the floating platform 72, and the weight device 75 presses the hot-pressing head 74 against the force sensor 100 for pre-pressing, and makes the heating module 73 contact the hot-pressing head 74. The camera module 8 detects the relative position of the force sensor 100 and the touch module 10 in real time. Further, after the camera module 8 confirms that the force sensor 100 and the touch module 10 are precisely mated, the lifting device... 71. The heating module 73 is pressed down, and the heating module 73 simultaneously heats the hot press head 74, thereby tightly attaching the force sensor 100 to the touch module 10, completing the precise assembly of the force sensor 100. Finally, the Y-axis moving module 4 moves the material picking device 6 away from the first positioning bottom mold 2, and at the same time, all other components return to their initial positions. The assembled product is then manually removed from the first positioning bottom mold 2. While the material picking device 6 is above the first positioning bottom mold 2 and continues to attach the force sensor 100, the force sensor 100 is manually placed and installed on the second positioning bottom mold 3, thereby realizing the alternating loading and unloading of the force sensor 100 and the touch module 10, achieving continuous assembly processing.
