[0028] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-2 The embodiment of the present invention is an automatic film laminating device for smart watches, comprising: a frame 1, a loading mechanism 2 provided on the frame, a unloading mechanism 3, a rotating table 4 for placing products, a transport mechanism 5, a film pre-laminating mechanism 6, a film final laminating mechanism 7, and a film laminating detection mechanism 8;

[0030] The frame is made of square steel and sheet metal welded together, with a solid structure. The frame module is sealed as a whole and is equipped with an anti-static device to reduce the impact of suspended particles in the equipment on the quality of the coating and ensure production quality. It should be noted that the anti-static device is a commercially available product in the existing technology.

[0031] The loading mechanism includes a feeding bin assembly, the unloading mechanism includes a receiving bin assembly, and the conveying mechanism 5 includes four four-axis robots, wherein the first four-axis robot 51 is used to convey the products in the feeding bin assembly to the fixture on the rotating table, and the second four-axis robot 52 is used to convey the products with the film applied to the receiving bin assembly. Each four-axis robot is equipped with a CCD camera. The four-axis robot can reduce the amount of equipment space occupied and can fully automatically load the products.

[0032] The film pre-lamination mechanism includes two roll film feeders. The third four-axis robot 53 and the fourth four-axis robot 54 are used to pre-laminate the film on the roll film feeder to the surface of the product. It should be noted that the roll film feeder is a commercially available product in the prior art.

[0033] like Figure 7 As shown, the film final lamination mechanism 7 is used to extrude the film pre-laminating on the product so that it is completely attached to the curved surface of the product. Specifically, the film final lamination mechanism includes a base 71, a slide cylinder 72 arranged on the base, a pressure plate 73 arranged on the slide cylinder, and a pressure maintaining head 74 arranged on the lower surface of the pressure plate. The part of the pressure maintaining head in contact with the product is made of elastic material. The soft elastic material is used to extrude the film pre-laminating on the product. After the elastic material is deformed, the film is completely attached to the curved surface of the product.

[0034] like Figure 8 As shown, the film detection mechanism 8 includes multiple groups of CCD cameras. The number of CCD cameras can be set according to usage requirements and is equipped with a light source. The CCD camera cooperates with the four-axis robot to detect the position of the grasped and positioned product. The CCD camera is also used to detect whether the position of the film attached to the product is correct. When it is detected that the film does not meet the standards, the second four-axis robot is used to move the product with unqualified film to the NG tray 9.

[0035] like Figure 3-6As shown, the structure of the feeding bin assembly is the same as that of the receiving bin assembly, which includes a bin fixing plate 21, a pull-out feeding bin 22, a pull-out receiving bin 23 and a tray mechanism 24, a feeding bin 25, a receiving bin 26 and a tray automatic transport mechanism 27. The bin fixing plate is slidably arranged on a pull-out guide rail 28, and the pull-out feeding bin and the pull-out receiving bin can be freely withdrawn by installing a pull-out handle. The pull-out feeding bin and the pull-out receiving bin can slide along the pull-out guide rail to just above the feeding bin and the receiving bin, and the in-position sensor is used to detect whether the pull-out feeding bin and the pull-out receiving bin have slid into position.

[0036] In addition, the structure of the pull-out feeding bin is the same as that of the pull-out receiving bin, both of which are formed by four "L"-shaped columns. A full-material sensor 210 is provided on the top of the "L"-shaped column, and a tray separation mechanism 211 is provided in the feeding bin and the receiving bin. The tray separation mechanism is used to separate the full trays in the pull-out feeding bin and cache them in the feeding bin. The tray automatic transport mechanism is provided above the tray mechanism and is used to realize the transfer of the trays.

[0037] The tray support mechanism is used to support the tray in the material replenishment bin and the material receiving bin, and includes a tray support cylinder 241, a movable guide rail 242 and a tray plate 243 arranged on the hopper fixed plate. The tray plate is slidably arranged on the movable guide rail, and the output end of the tray support cylinder drives the tray plate to slide back and forth along the movable guide rail.

[0038] The tray distribution mechanism 211 includes a frame 2111, a tray distribution cylinder 2113 arranged on the frame through a vertical plate 2112, and an electric cylinder 2114 arranged under the frame. The output end of the electric cylinder passes through the bottom plate of the frame and is connected to the lifting plate 2115. Four guide columns 2116 are provided on the lifting plate. The top end of the guide column passes through the bearing 2117 on the top plate of the frame and is connected to the suction cup mounting plate 2118. A plurality of suction cups 2119 for adsorbing the tray are provided on the suction cup mounting plate. The structure of the feeding bin and the receiving bin is the same, and is formed by four "L"-shaped baffles arranged on the top of the vertical plate.

[0039] The tray automatic transport mechanism 27 includes a KK linear module 271 and a tray transfer tray 272 slidably arranged on the KK linear module. Waist-shaped holes 273 are provided on both sides of the tray transfer tray. When the pull-out feeding bin and the pull-out receiving bin slide to the top of the supply bin and the receiving bin and merge into place, the tray transfer tray slides on the KK linear module to the bottom of the pull-out feeding bin. At this time, the tray support cylinder retracts, and the electric cylinder lifts the lifting plate to drive the suction cup mounting plate to pass through the waist-shaped holes on both sides of the tray transfer tray. The suction cup sucks the tray of the bottom layer, and the tray cylinder extends out to cooperate with the suction cup to realize the separation of a single tray from the silo. The few separated trays are temporarily cached in the supply silo. When the pull-out feeding silo is pulled out, a certain number of full trays will remain in the supply silo, so that the entire silo has materials, so that the entire equipment does not need to be shut down.

[0040] To sum up, the present invention points out an automatic film-sticking device for smart watches, in which the loading mechanism adopts a tray hopper for non-stop feeding, and the tray can be safely and quickly fed by pulling and pulling, which greatly reduces the operating cost and can effectively solve the problem of equipment shutdown caused by feeding; the use of a four-axis robot can greatly save equipment space and greatly reduce the complexity of the handling mechanism.

[0041] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
