In electronic products, silicon foam is a commonly used sealing foam material. The tightness of the electronic product is influenced by the tightness between the silicon foam and the component in addition to the performance characteristics of the component and the silicon foam. In order to obtain good sealing performance, a layer of self-adhesive is often coated on the surface of the silicon foam for improving the sealing performance between the silicon foam and the component. Therefore, the surface sizing effect of the silicon foam becomes one of important factors affecting the sealing property.

The second drive mechanism 41 is the main drive unit responsible for pulling the silicon foam from the discharge device 1 to the receiving device 4. The first driving mechanism 11 is for leveling the transfer of the silicon foam, and thus provides a resistance against the advancement thereof. In fig. 1, the guide roller A2 is referred to in each device.
The discharging device 1 is provided with silicon foam to be glued, and is used for conveying the silicon foam to be glued on the discharging device to the gluing device 2 in a flat state under the traction of the second driving mechanism 41 and the obstruction of the first driving mechanism 11.

Correspondingly, the second driving mechanism 41 must be larger than the first driving mechanism 11 in terms of driving power to ensure that the silicon foam can finally travel. Preferably, the second driving mechanism 41 is a deceleration electrode, and the start and stop of the deceleration electrode are controlled through a button to power the running of the silicon foam.
The glue applicator 2 comprises a paint box 21 with glue and a glue applicator 22 partially immersed in the glue in the paint box 21, and is used for driving the glue applicator 22 to rotate under the traction of the second driving mechanism 41 by the silicon foam to be glued, so that the glue on the glue applicator 22 is coated on the silicon foam to form a glue layer. Preferably, the glue spreading device 2 further comprises a glue spreading auxiliary roller 23 spaced from the glue spreading roller 22, and the glue spreading auxiliary roller 23 can ensure that glue is evenly and uniformly attached to the silicon foam. Before the gluing, the spacing between the glue spreader 22 and the glue spreader auxiliary 23 can be adjusted based on the thickness of the silicon foam, preferably compressing the silicon foam to 0.6-1.0 mm. The glue coating auxiliary roller 23 is matched with the glue coating roller 22 to compress the silicon foam with the formed glue layer, so that the glue layer is uniformly and continuously attached to the silicon foam with a preset thickness, and the uniform, continuous and full glue layer on the silicon foam is ensured.

A liquid level measuring device for measuring the liquid level of the glue is provided in the paint cartridge 21 at a position away from the paint roller 22; and stopping gluing when the glue in the paint box is lower than a preset liquid level.
Wherein, the silicon foam to be glued enters between the glue spreader 22 and the glue spreader 23 in a posture parallel to the rotation tangential direction of the glue spreader 22 and the rotation tangential direction of the glue spreader 23 at the same time. The glue spreader 22 is located right below the glue spreading auxiliary roll 23, and the plane formed by the rotation shafts of the glue spreader 22 and the glue spreading auxiliary roll 23 is perpendicular to the gesture before the silicon foam enters the glue spreader 22 and the glue spreading auxiliary roll 23. Preferably, the applicator roll 22 and the applicator auxiliary roll 23 use guide rolls of the same size to ensure that the application can be performed with sufficient pressing area and pressing force. Further preferably, a guiding roller A2 is arranged in the gluing device, a plane formed between the top of the guiding roller A2 and the top of the gluing roller 22 is perpendicular to a plane formed by the rotating shafts of the gluing roller 22 and the gluing auxiliary roller 23, so that the silicon foam is glued in a posture perpendicular to the gluing roller and the gluing auxiliary roller, and the uniformity and the completeness of gluing are ensured.
Illustratively, the applicator device 2 is comprised of a guide roller A2, a paint cartridge 21, an applicator roller 22, and applicator roller 22 auxiliary wheels. The guide roller A2 is made of galvanized sheet and is responsible for guiding the silicon foam on the discharging device 1 between the gluing auxiliary roller 23 and the gluing roller 22, and guiding the glued silicon foam to leave the gluing device 2 and enter the baking device 3.

It is further preferable that the heating time is controlled by adjusting the material receiving speed, i.e., the output power of the second driving mechanism 41, and the heating time is generally 3 to 5 minutes. After heating, the glue layer on the surface of the silicon foam becomes a glue coating layer.
Preferably, the baking device comprises an electric heating tube, an inlet heating roller and an outlet heating roller. Heating rollers can be added between the inlet heating roller and the outlet heating roller according to the heating area of the electric heating pipe so as to ensure uniform baking. If the height of the silicon foam before entering the baking device is a first height and the height of the silicon foam after leaving the baking device is a second height, the silicon foam enters the baking device in a posture not lower than the first height through the inlet heating roller and leaves the baking device in a posture not lower than the second height through the outlet heating roller. The inlet heating roller and the outlet heating roller need to ensure that the silicon foam travels in the baking device in a posture not lower than before the silicon foam enters the baking device. In the drawing, the silicon foam advances in a line before and after entering and exiting the baking device and inside the baking device, so that the baking is more uniform.
The silicon foam with the glue coating layer is guided into the material receiving device 4 by the guide roller A2.
