Description

Technical Field

[0001] This application belongs to the technical field of dispensing and positioning devices, specifically relating to a silicone adhesive dispensing and positioning device for touch modules. Background Technology

[0002] The touch module is the core component for realizing touch interaction functions. It is usually composed of touch sensors, controller circuits, software drivers and structural support components. It can convert the user's touch actions into instructions that electronic devices can recognize. It is one of the core components of touch screen devices such as mobile phones, tablets, smart terminals, and industrial control panels.

[0003] The silicone adhesive dispensing and positioning device for touch modules is a key piece of equipment used in the production process of touch modules to precisely control the coating of silicone adhesive. It is mainly used to accurately apply silicone adhesive material in a specific shape, position and quantity to the designated area of ​​the touch module.

[0004] In existing technologies, when relying on ordinary motors or manual adjustment, the dispensing speed is limited and cannot quickly respond to the positioning requirements of workpieces of different sizes. When multiple dispensing points are required, the consistency of the positions of each dispensing point is poor, which affects the bonding strength between the module and the touch screen. Furthermore, the use of rigid pressure plates to directly press down cannot adapt to the thickness tolerance of the module. At the same time, without lateral and angle adjustment functions, the device can only be used for dispensing modules of fixed size, which cannot meet the flexible production needs of different models of products.

However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0055] In some embodiments, please refer to Figures 1 to 6 This application provides a silicone adhesive dispensing and positioning device for a touch module, including a base 1;

[0056] Dispensing positioning component 8 is installed on the top of base 1;

[0057] Angle plate 801 is installed on the top of base 1;

[0058] Servo motor 802 is mounted on one side of the outer wall of corner plate 801;

[0059] Positioning stage 803 is sleeved on the shaft end of servo motor 802;

After the base 1 is fixed, it provides effective support for the above-mentioned components to ensure the stable operation of the equipment. The touch module can be manually placed in the center of the positioning platform 803.

During the movement, the four sets of second springs 813 can ensure that the four electric cylinders 805 will not generate large vibrations when moving clockwise, and at the same time ensure that the L-shaped plate 808 provides effective buffering during the return stroke.

[0094] In this embodiment, the electric push rod 809 at the top of the L-shaped plate is activated, and the transmission shaft passes downward through the L-shaped plate, causing the pressure plate 810 to contact the upper surface of the module. At this time, the telescopic rod 811 begins to compress, and the four sets of first springs 812 are simultaneously deformed by force to form a buffer. At the same time, the four electric push rods 809 can convert electrical energy into mechanical energy to drive the four pressure plates 810 to make linear motion, thereby completing the clamping work of the touch module.

[0095] In some embodiments, the bottom of each of the four pressure plates 810 is covered with an anti-slip silicone sleeve.
