[0002] In the electronics manufacturing industry, the packaging of circuit board panels is crucial to product transportation and storage. Traditional packaging methods mostly rely on manual or semi-automatic equipment, which have problems such as low efficiency, poor precision, and insufficient consistency, and it is difficult to meet the modern electronics industry's demand for efficient and accurate packaging. In particular, with the diversification of circuit board sizes and shapes, traditional methods can no longer adapt.

In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0043] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, it can be a mechanical connection, it can be an electrical connection, it can be a direct connection, it can be connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

The roller conveying module 111 includes a plurality of conveying rollers 1111 arranged at intervals, and the plurality of conveying rollers 1111 are driven to rotate synchronously by a transmission belt and a motor to drive the product to feed along the X-axis direction. The first lifting module 112 includes a first lifting frame 1121 arranged at the bottom of the conveying roller 1111 and a first roller group 1122 arranged at the upper end of the first lifting frame 1121, the first lifting frame 1121 is equipped with a cylinder, and the first roller group 1122 is spaced apart from the conveying roller 1111; the first clamping module 113 includes two groups of symmetrically arranged first movable arms 1131, and the two groups of first movable arms 1131 are connected with a transmission belt and a motor. Specifically, a clamping plate 1132 is provided on the relative inner side of the first movable arm 1131, and a baffle is provided at the end of the conveying path of the roller conveying module 111, and a cylinder is provided at the lower end of the baffle. When working, the product is placed on the roller conveying module 111. When it moves a certain distance, the cylinder drives the first lifting frame 1121 and the first roller group 1122 to move upward, thereby lifting the product and separating it from the conveying roller 1111; then the transmission belt and the motor drive the two groups of first movable arms 1131 to move closer to each other to clamp the product. During this period, the product moves on the first roller group 1122 to achieve the positioning of the product in the Y-axis direction. After the positioning is completed, the first lifting frame 1121 descends, and the product falls onto the conveying roller 1111 and continues to feed. It should be noted that when positioning is performed, the baffle rises to block the product. After the positioning is completed, the baffle descends, and the product enters the X-axis positioning mechanism 12.

[0047] Specifically, the X-axis positioning mechanism 12 includes a belt conveyor module 121, a second lifting module 122 and a second clamping module 123; the belt conveyor module 121 includes a plurality of spaced apart conveyor belts 1211, the second lifting module 122 includes a second lifting frame 1221 disposed at the bottom of the conveyor belt 1211 and a second roller group 1222 disposed at the upper end of the second lifting frame 1221, the second roller group 1222 is spaced apart from the conveyor belt 1211, the second clamping module 123 includes two groups of symmetrically disposed second movable arms 1231, and in this embodiment, the second movable arm 1231 is connected to a linear module.

[0048] The Y-axis positioning mechanism 11 and the X-axis positioning mechanism 12 are respectively provided with a first lifting module 112 and a second lifting module 122 to lift the product for positioning, integrating the positioning function and the feeding function to improve the work efficiency, while having a compact structure and reducing the occupied area.

[0049] like Figure 4 and Figure 5 As shown, the feed positioning unit 10 further includes a desiccant delivery mechanism 13 disposed above the Y-axis positioning mechanism 11 for delivering desiccant.

[0050] During operation, the desiccant with a strip structure is placed in the guide track, the clamping module 133 clamps one end of the desiccant and pulls the desiccant out of the desiccant guide track 131. When the desiccant is pulled out by a preset distance, the shearing module 132 shears and separates the desiccant. At the same time, the clamping module 1344 of the feeding robot 134 clamps the sheared desiccant and moves it to the preset delivery position through the third Y-axis driving module 1341, the third X-axis driving module 1342, and the third Z-axis driving module 1343. Finally, the clamping module 133 is released to deliver the desiccant.

The feed port 61 is provided on one side of the feed positioning unit 10, and the discharge port 62 is provided on one side of the unloading unit 50.

[0064] The working steps of the hot melt packaging complete line system involved in the present invention are as follows:

[0065] S1. The feeding and positioning unit 10 is used to load and position the packaged product;

[0066] S2. The transfer robot 22 transfers the positioned product from the loading and positioning unit to the first transmission mechanism 21; the first transmission mechanism 21 transfers the product to the bottom of the laminating heat shrink mechanism 23;

[0067] S3. The film-covering heat shrinking mechanism 23 covers the upper end of the product with a heat shrinkable film, and simultaneously uses vacuum and high temperature to bond the heat shrinkable film to the base film, thereby packaging the product between the heat shrinkable film and the base film;

[0068] S4. The cutting unit 30 performs cutting to separate a plurality of packaged finished products.

[0069] Compared with the prior art, the hot melt packaging complete line system involved in the present invention places the product on the base film and covers the upper end of the product with a heat shrink film through the coordinated cooperation of a feed positioning unit 10, a vacuum heat shrink packaging unit 20, a cutting unit 30, and a base film retracting and releasing unit 40, and completes the packaging of the product through heat shrinking and cutting; the above operations are completed and product packaging is realized through fully automated equipment, which significantly improves the packaging effect and reduces labor costs; in addition, the feed positioning unit 10 is provided with a Y-axis positioning mechanism 11 and an X-axis positioning mechanism 12, which can position the product in the X-axis and Y-axis directions to improve the accuracy of subsequent product packaging; the vacuum heat shrink packaging unit 20 includes a negative pressure generating mechanism 24, which can create negative pressure between the base film and the heat shrink film to ensure uniform shrinkage of the heat shrink film and ensure the tightness and aesthetics of the packaging; the base film retracting and releasing unit 40 drives the base film to pass through the vacuum heat shrink packaging unit 20 and the cutting unit 30, and recycles the waste after cutting to improve packaging efficiency.

[0070] The above only expresses the preferred technical solution of the present invention, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, and the present invention is also intended to include these modifications and modifications.
