The first support frame 21 is arranged in the vertical direction, and the first film wrapping assembly 22 and the second film wrapping assembly 23 are arranged on the support frame 1 at intervals in the vertical direction. Specifically, the second film wrapping assembly 23 can be arranged at the top, and the first film wrapping assembly 22 can be arranged at the bottom, and a first accommodating space is formed between the first film wrapping assembly 22 and the second film wrapping assembly 23 for the feeding mechanism 1.

[0054] During the operation of the first wrapping mechanism 2, the first wrapping component 22 moves upward to lift up the two sides of the packaging film 6, so that the two sides of the main part 61 of the packaging film 6 are bent upward in the vertical direction and respectively adhered to the two side surfaces of the workpiece, and the second wrapping component 23 bends the parts of the two sides of the main part 61 of the packaging film 6 that are not adhered to the side surfaces of the workpiece toward each other in the horizontal direction above the workpiece, so that the two sides of the main part 61 of the packaging film 6 are bonded by the adhesive layer 611, and the adhesive layer 611 at the bonding notch is exposed.

[0055] In one embodiment, the first film packaging assembly 22 includes a first cylinder 221 and a first roller assembly 222; the first cylinder 221 is mounted on the first support frame 21 in the vertical direction; the first roller assembly 222 is mounted on the first cylinder 221; the first roller assembly 222 includes two first rollers arranged in the vertical direction, and a receiving position for accommodating the workpiece is formed between the two first rollers, and the first roller assembly 222 is used to move in the vertical direction under the drive of the first cylinder 221, so that the two first rollers will bend the two sides of the main part 61 of the packaging film 6 in the same vertical direction, and partially fit on the two side surfaces of the workpiece.

[0056] As an example, the first film encapsulation assembly 22 includes a first cylinder 221 and a first roller assembly 222.

The sixth cylinder 333 can drive the fifth cylinder 331 and the fourth roller assembly 332 to move up and down in the vertical direction.

[0082] During the operation of the wrapping mechanism, after the third wrapping assembly 32 adheres the wrapping film 6 to the bottom surface of the workpiece, the sixth cylinder 333 drives the fifth cylinder 331 and the fourth roller assembly 332 to move downward so that the fourth roller assembly 332 can bend the part of the side wing part 62 of the wrapping film 6 that is not adhered to the bottom surface of the workpiece in the horizontal direction during the horizontal movement, and bond it to the adhesive layer 611 at the bonding notch. After the fourth roller assembly 332 completes its work, the sixth cylinder 333 drives the fifth cylinder 331 and the fourth roller assembly 332 to move upward and reset.

[0083] In one embodiment, the coating device further includes a first workpiece positioning assembly 4 disposed in the first coating mechanism and a second workpiece positioning assembly 5 disposed in the second coating mechanism; the first workpiece positioning assembly 4 and the second workpiece positioning assembly 5 are disposed opposite to the feeding mechanism 1 for positioning the workpiece.

[0084] As an example, the coating device also includes a first workpiece positioning assembly 4 and a second workpiece positioning assembly 5; the first workpiece positioning assembly 4 is mounted on the first support frame 21, and the second workpiece positioning assembly is mounted on the second support frame 31. The first workpiece positioning assembly 4 and the second workpiece positioning assembly 5 are arranged above the feeding mechanism 1, and are used to position the workpiece before the first coating mechanism 2 and the second coating mechanism 3 perform coating processing on the workpiece. Specifically, the workpiece can be positioned by fixing the pins of the workpiece.
