[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Example

[0028] Reference Figures 1 to 6 , is an embodiment of the utility model, which provides an automatic film-sticking device with automatic feeding and receiving, such as Figure 1 , Figure 2 , Figure 5-Figure 6 As shown, the connecting block 102 on the supporting beam 101 is connected to the film pressing driving member of the film laminating machine, and is used to drive the film pressing assembly 100 to reciprocate up and down. The bottom of the supporting beam 101 is connected to the piston cylinder 103 and the piston rod 104. By arranging a reset member 106 in the piston cylinder 103, the piston cylinder 103 and the piston rod 104 at this time play a buffering effect on the pressure exerted by the driving member on the electronic component;

[0029] like Figure 5 As shown, the fixing block 105 on the piston rod 104 is used to fix the shaft 107a, and the shaft 107a is sleeved with a film pressing roller 107 that can rotate along the shaft 107a, and the outer surface of the film pressing roller 107 is sleeved with a rubber sleeve 107b for laminating the electronic parts;

[0030] like Figure 6 As shown, compared Figure 5 The fixed block 105 on the piston rod 104 is equipped with a film pressing plate 108, and the film pressing arc surface 108a at the bottom of the film pressing plate 108 is used for pressing the rubber sleeve 107b of the electronic component;

[0031] like Figure 2-Figure 4 As shown, a vent hole 103b is provided on the side of the piston cylinder 103. When the piston rod 104 squeezes the air inside the piston cavity 103a of the piston cylinder 103, the air is exhausted outward through the vent hole 103b. By escaping the gas outward, the pressure exerted by the lamination roller 107 / lamination plate 108 on the electronic component in an instantaneous contact can be reduced, and the pressure exerted by the electronic component is decreasing.

[0032] In order to further improve the film pressing roller 107 / film pressing plate 108 during film pressing, the buffer pressure is gradually reduced, such as Figure 3-Figure 4 As shown, a valve assembly 200 is installed in the exhaust hole 103b opened on the side of the plug tube 103. The valve assembly 200 is composed of an inlet and outlet valve 201 and a valve ball 203 inside the inlet and outlet valve 201. The inlet and outlet valve 201 is arranged in the exhaust hole 103b.

[0033] like Figure 3 As shown, the inlet and outlet valve 201 is located at the gas guide end 201a at the outer end of the piston cylinder 103, and the gas inlet end 201b is located inside the piston cylinder 103. There is an arc transition between the gas guide end 201a and the gas inlet end 201b, wherein the valve ball 203 can roll freely on the arc transition between the gas guide end 201a and the gas inlet end 201b and the gas inlet end 201b, and the gas inlet end 201b is provided with a grid 202 to prevent the valve ball 203 from falling into the piston cylinder 103, and the size of the valve ball 203 is slightly larger than the aperture of the gas guide end 201a, but the size of the valve ball 203 is smaller than the aperture of the gas inlet end 201b;

[0034] Furthermore, a plurality of groups of first air holes 203a and second air holes 203b are formed on the outer surface of the valve ball 203, and the first air holes 203a and the second air holes 203b are interconnected to form an air-permeable cavity 203-1;

[0035] Combination Figure 3 , Figure 4 Furthermore, the aperture of the air guide end 201a is 2 / 3 of the aperture of the air inlet end 201b. When the piston rod 104 squeezes the air in the piston cavity 103a inside the piston cylinder 103, the gas is discharged from the air inlet end 201b of the air inlet and outlet valve 201, pushing the valve ball 203. The valve ball 203 blocks the air guide end 201a. Most of the gas can only be discharged from the first air hole 203a, the second air hole 203b and the air cavity 203-1 of the valve ball 203. This will reduce the gas discharged from the piston cavity 103a per unit time. For this reason, there is a certain pressure inside the piston cavity 103a. At the same time, the gas is still being discharged, which prolongs the time for discharging the piston cavity 103a, thereby prolonging the decreasing time of the pressure, thereby achieving a better effect of decreasing buffering for electronic components during film pressing, such as Figure 4 As shown, the first air hole 203a, the second air hole 203b and the air cavity 203-1 of the valve ball 203 are interconnected, and the gas will form a backflow inside the valve ball 203 when it is discharged, which can further extend the pressure reduction time;

[0036] Combination Figure 3 , Figure 4 Furthermore, when the film pressing stops, the reset member 106 inside the piston cylinder 103 will reset the piston rod 104. At this time, the external gas will be sucked in through the inlet and outlet valves 201. Since the hole of the air guide end 201a is smaller than the inlet end 201b, the gas flow rate will increase. At the same time, the valve ball 203 will be sucked to the inlet end 201b, increasing the flow aperture of the gas circulation. Since the size of the valve ball 203 itself is smaller than the aperture of the inlet end 201b, the air will quickly enter the piston cavity 103a of the piston cylinder 103, which is conducive to the rapid reset of the piston rod 104 and does not affect the normal film sticking speed.

[0037] It is worth mentioning that since the inlet and outlet valves 201 and the piston cylinder 103 account for a relatively small proportion in the automatic film laminating device, a simple structural design is adopted. The different inner diameters of the inlet and outlet valves and the setting of the valve ball that can roll freely not only meet the requirements of small size, but also save costs. Compared with other alternatives, this simple structural design is easier to implement and reduces the risk of failure caused by complex structures.

[0038] Importantly, it should be noted that the construction and arrangement of the present application shown in a plurality of different exemplary embodiments are only exemplary. Although only a few embodiments are described in detail in this disclosure, it should be readily understood by those who refer to this disclosure that many modifications are possible (e.g., the size, scale, structure, shape and ratio of various elements, and parameter values ​​(e.g., temperature, pressure, etc.), installation arrangements, use of materials, color, directional changes, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in the application. For example, the element shown as integrally formed can be composed of multiple parts or elements, the position of the element can be inverted or otherwise changed, and the nature or number or position of the discrete element can be changed or changed. Therefore, all such modifications are intended to be included in the scope of the present utility model.

Without departing from the scope of the present invention, other substitutions, modifications, changes and omissions may be made in the design, operating conditions and arrangement of the exemplary embodiments. Therefore, the present invention is not limited to a specific embodiment, but extends to various modifications that still fall within the scope of the appended claims.

[0039] Additionally, in order to provide a concise description of example embodiments, all features of an actual embodiment (ie, those features that are not relevant to the best mode presently contemplated for carrying out the invention or those that are not relevant to implementing the invention) may not be described.

[0040] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.
