By using the slide cylinder, the pressure of the primer head on the glass with the same contact area can be kept constant, and the problem of uneven pressure caused by the ups and downs of the primer track can be avoided. The proportional valve outputs corresponding analog signals through program control, so that the pressure of the primer head on the glass can change with the contact area. Different contact areas can automatically change the pressure, so that the pressure (i.e. pressure) of the foam in the unit area is the same, the excessive wear of the foam is reduced, and the primer effect is better.

[0019] Please refer to Figs. 1-3 The application provides a technical scheme: a primer head mechanism for automatically adjusting pressure for glass primer coating, comprising a primer head 1, a sliding table air cylinder 2 arranged below the primer head 1, the primer head 1 being sequentially connected with an electromagnetic valve 4, a proportional valve 5 and a pneumatic three-way joint 6 through an air pipe 3, a foam 8 arranged at the bottom of the sliding table air cylinder 2, a glass 7 arranged at the bottom of the foam 8, a mounting flange 11 arranged at the top of the primer head 1, a primer head bolt 10 arranged at the right side of the primer head 1, and a feeding pipe 11 arranged above the primer head bolt 10, which solves the problem that a layer of primer glue needs to be coated on the glass before injection molding and edge covering, and the primer head used is mostly foam, the foam has good flowability, and the coating is more uniform and flat compared with other materials, but the foam is easy to wear and tear, and the current primer head mechanism cannot automatically control the pressure used on the glass with different contact areas due to different coating widths, which aggravates the problem of foam wear and tear.

[0020] The sliding table air cylinder 2 drives the primer head 1 to float, so that the pressure of the primer head 1 on the glass 7 with the same contact area is constant.

[0021] The sliding table air cylinder 2 changes the internal pressure through the output air pressure of the proportional valve 5.

[0022] The proportional valve 5 changes the pressure of the primer head 1 on the glass 7 with the change of the contact area.

[0023] The glass 7 is vertically arranged at the lower part of the sliding table air cylinder 2.

[0024] The working principle of the application is that the proportional valve 5 outputs corresponding air pressure through program control, so as to control the pressure of the sliding table air cylinder 2, when the foam 8 is completely pressed on the glass 7, the air pressure is set as a, the pressure of the foam 8 on the glass 7 is b, when the foam 8 is only half pressed on the glass 7, the proportional valve 5 controls the proportion by outputting corresponding analog quantity, the air pressure is reduced to 0.5a, and then the pressure of the foam 8 on the glass 7 is changed to 0.5b, so that the foam 8 is constantly deformed, the pressure of the foam in the unit area (i.e. the pressure) can be automatically changed, the foam wear and tear is reduced, and the primer effect is better.
