The third driving unit 135 drives the second mounting table 131 to move in the first direction to cooperate with the coating die 132, so as to apply the glue in the coating die 132 to the product. After the coating die 132 applies the glue to the product, the second heating member 1313 starts to heat the product fixed to the second adsorption plate 1312 to reduce the surface tension of the glue. The friction force of the glue on the surface of the product is larger than the surface tension of the glue, so that the glue is prevented from shrinking too fast to form pits and bubbles, and the effect of accelerating the curing efficiency of the glue coating 230 on the surface of the product is achieved. Optionally, the second heating element 1313 and the heating device 139 are activated simultaneously to heat the product from both sides of the product.

Optionally, a second thermal shield 1314 is disposed between the second mounting plate 1311 and the second heating element 1313. In the coating apparatus 130, the second heat insulating plate 1314 is used to prevent the second heating member 1313 from conducting heat to the second stage 137, thereby preventing a person from being scalded. Alternatively, in other embodiments, the second table 131 may include only the second mounting plate 1311. In the gluing process, the product to be glued is placed directly on the second mounting plate 1311.

Before gluing the product to be glued, the vacuum chamber 140 needs to be vacuumized, so as to remove air bubbles in the glue coating 230. Alternatively, the vacuum formation may be formed by a negative pressure drive, which may employ a vacuum pump. After the glue is applied to the product, the product is allowed to stand to solidify the glue, and since the product is placed in the vacuum chamber 140, the bubbles float upward when the bubbles are present in the glue. Alternatively, one side of the vacuum chamber 140 may be opened for putting in a product to be gummed or taking out a gummed product.

Optionally, when the product is still, the second heating member 1313 and the heating device 139 heat the product from the front and back sides of the product simultaneously, so as to increase the floating speed of the bubbles in the glue coating 230.

The bubble discharging principle of the standing pre-curing platform is as follows: by the formula:

the temperature is increased, the volume of bubbles in the liquid is increased, the pressure intensity is reduced, the buoyancy of the bubbles is greater than the gravity, and the bubbles float upwards in an accelerated manner; the pressure inside the vacuum chamber 140 is lower than the pressure inside the bubbles, and the bubbles break after reaching the liquid level, completing bubble discharge.

And comprehensively considering the air pumping amount and the air pumping time to determine the type of the air pumping pump and the size of the cavity.

According to the application, before the coating device 130 coats glue on the product to be glued, the plasma cleaning head 112 is used for cleaning the product to be glued, so that the roughness of the surface of the product to be glued is enhanced, and the friction force of the glue on the surface of the product is enhanced. The friction force is larger than the surface tension of the glue, so that the movement of the glue is reduced, and the quantity of pits and bubbles generated on the surface of the glue is reduced.

The above description is only a part of the embodiments of the present application, and not intended to limit the scope of the present application, and all equivalent devices or equivalent processes performed by the content of the present application and the attached drawings, or directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
