As shown in fig. 1, the film sticking apparatus provided in this embodiment includes a support 1, a driving member 2, a pressing head 3, an application head assembly 4, and a pressure detecting member 5. Wherein the bracket 1 is used for supporting each component, and the driving member 2 is used for driving the driving pressure head 3, the attaching head assembly 4 and the pressure detecting member 5 to move in the vertical direction. The lower end of the attaching head assembly 4 is used for pressing the membrane 10, and the pressure head 3 is used for pressing against the pressure detection piece 5 so as to accurately detect the pressure of the film attaching device on the membrane 10.

Specifically, the driving member 2 is connected to the bracket 1, the pressing head 3 is connected to an output end of the driving member 2, and the driving member 2 can drive the pressing head 3 to reciprocate in the vertical direction.

Attached head subassembly 4 activity joint in pressure head 3 to can move along vertical direction for pressure head 3, and can follow pressure head 3 along vertical direction reciprocating motion. The pressure detecting member 5 is attached to the upper end of the attaching head assembly 4. When attached head subassembly 4 and diaphragm 10 were equipped with the interval, attached head subassembly 4 joint was equipped with the interval of predetermineeing on pressure head 3 between pressure head 3 and the pressure detection spare 5. When the attaching head assembly 4 drives the membrane 10 to contact the product, the pressing head 3 slides in the vertical direction relative to the attaching head assembly 4, or the pressing head 3 abuts against the pressure detecting member 5. It should be noted that, the attachment head assembly 4 provided in this embodiment has a vacuum absorption hole, and the attachment head assembly 4 firstly absorbs the film 10 and then drives the film 10 to attach to the product. In attaching the film 10 to the product, the film 10 is first brought into contact with the product, and then the attaching head assembly 4 applies downward pressure to the film 10 and holds the pressure for a certain time to bond the film 10 to the product.

In the film sticking apparatus provided in this embodiment, the pressure applied to the film 10 by the head assembly 4 is transmitted to the head assembly 4 by the pressure of the indenter 3 via the pressure detector 5. When attaching the adsorbed diaphragm 10 of head subassembly 4 and product were equipped with the interval, attaching head subassembly 4 joint was on pressure head 3, and pressure head 3 and pressure detection spare 5 are equipped with preset interval to guarantee before attaching the adsorbed diaphragm 10 of head subassembly 4 supports to press the product, the pressure of pressure detection spare 5 returns to zero. And, because the 4 joints of attached head subassembly are on pressure head 3 this moment, therefore, the 3 downstream of drive ram of driving piece 2, attached head subassembly 4 also can be along with pressure head 3 downstream, when the adsorbed diaphragm 10 of attached head subassembly 4 just contacted with the product, attached head subassembly 4 is spacing by the product, can't continue to move, but because pressure head 3 and pressure detection spare 5 are equipped with and predetermine the interval, consequently driving piece 2 still drives 3 downstream of drive ram and supports to press on pressure detection spare 5, driving piece 2 continues to drive 3 of pressure ram and pushes down pressure detection spare 5, until the pressure value of pressure detection spare 5 reaches the default, pressure detection spare 5 gives attached head subassembly 4 with pressure transmission, attached head subassembly 4 pushes down diaphragm 10.

Because attached head subassembly 4 adsorbed diaphragm 10 before contacting with the product, pressure head 3 is equipped with the interval with pressure detection spare 5, pressure detection spare 5 detected value is zero, only after pressure head 3 applys pressure to pressure detection spare 5, pressure head 3 just can contact with pressure detection spare 5, the pressure value that pressure detection spare 5 detected this moment just can be greater than zero, consequently, the pad pasting device itself can not be disturbed to the detection form noise of pressure detection spare 5, pressure detection spare 5 can the accurate pressure value that detects pressure head 3. The pressure head 3 directly supports and presses the pressure detection piece 5 to generate a pressure value, namely, the pressure value displayed by the pressure detection piece 5 is the pressure actually applied by the pressure head 3, when the pressure applied by the pressure head 3 is linearly increased, the pressure detected by the pressure detection piece 5 is also linearly increased, and the sum of the gravity of the detection assembly and the gravity of the attachment head assembly 4 is a fixed value, so that the pressure value received by the diaphragm 10 is also linearly increased.

When the adsorbed diaphragm 10 of attached head subassembly 4 just contacted with the product, attached head subassembly 4 is spacing by the product, can't continue to remove, but because pressure head 3 is equipped with preset interval with pressure detection spare 5, consequently driving piece 2 still drives pressure head 3 and continues the lapse in joint hole 411 until pressure head 3 supports and presses pressure detection spare 5. After the pressurize finishes, driving piece 2 drive pressure head 3 upwards slides in joint hole 411 until the up end of pressure head 3 and flange 4151's lower surface butt, and driving piece 2 continues to drive pressure head 3 upward movement, and pressure head 3 then can drive joint spare 41 upward movement.
