Among them, the insulating film unwinding mechanism 2 is connected to the large film coating mechanism 4, and the insulating film unwinding mechanism 2 is used to unwind the insulating film to the large film coating mechanism 4. In this embodiment, the insulating film unwinding mechanism 2 can use an existing unwinding mechanism, which will not be described here. The feeding mechanism 1, the large film coating mechanism 4, the side film coating mechanism 3, and the feeding mechanism 4 are connected in sequence. The feeding mechanism 1 feeds the product to the large film coating mechanism 4, and the large film coating mechanism 4 coats three surfaces of the product and then transfers the product to the side film coating mechanism 3.

[0028] Please refer to Figure 2 The feeding mechanism 1 includes a feeding robot 11 and a first transfer track 12. One end of the first transfer track 12 is close to the large film wrapping mechanism 4, and the feeding robot 11 is slidably connected to the first transfer track 12. The product to be wrapped is clamped and fed to the large film wrapping mechanism 4 by the feeding robot 11. Specifically, the feeding robot 11 includes relatively arranged clamping jaws 111 and a first driving member 112. The first driving member 112 is connected to the clamping jaws 111. The first driving member 112 can drive the clamping jaws 111 to move toward each other, thereby clamping the product from both sides. The feeding robot 11 drives the product to move along the first transfer track 12 to the large film wrapping mechanism 4. The first driving member 112 drives the clamping jaws 111 to loosen, thereby placing the product on the large film wrapping mechanism 4, thereby achieving fast and accurate feeding.

[0029] Please refer to Figure 3 The large film wrapping mechanism 4 includes a pushing unit 41 for driving the product to move in a horizontal direction, a first tensioning unit 42 for cutting and clamping the insulating film, and a second tensioning unit 43 for vertically tensioning the insulating film. The first tensioning unit 42 and the second tensioning unit 43 are arranged opposite to each other up and down, and the pushing unit 41 is arranged between the first tensioning unit 42 and the second tensioning unit 43.

[0030] The pushing unit 41 includes a first driving unit 418, which includes two parallel first guide rails 411 and a second driving member 417. A second transfer rail 412 is provided between the first guide rails 411, and a plurality of rollers are arranged on the surface of the second transfer rail 412. The extension direction of the second transfer rail 412 is parallel to the extension direction of the first guide rail 411. The second transfer rail 412 is provided with an avoidance notch 413 at the position corresponding to the first tensioning unit 42 and the second tensioning unit 43. The avoidance notch 413 is used to avoid the insulating film, so that the insulating film can vertically block the forward direction of the second transfer rail 412 under the cooperation of the first tensioning unit 42 and the second tensioning unit 43. A clamping unit 414 for clamping a product is provided on the first guide rail 411, and the clamping unit 414 is slidably connected to the first guide rail 411.

The clamping unit 414 includes a clamping block 415 and a third driving member 416. The third driving member 416 is connected to the clamping block 415. The clamping block 415 can move horizontally toward the second transfer track 412 under the drive of the third driving member 416, thereby clamping the product from both sides of the product. When the clamping unit 414 slides along the first guide rail 411, it can drive the product to move along the second transfer track 412.

[0031] Please refer to Figure 4 A positioning unit 44 is provided at one end of the pushing unit 41 close to the feeding mechanism 1. The positioning unit 44 includes a positioning plate 442, a first positioning cylinder 445, a blocking unit 447, and a limiting unit 448. The blocking unit 447 includes a positioning roller 441 and a second positioning cylinder 444, and the limiting unit 448 includes a push plate 443 and a third positioning cylinder 446. The push plate 443 is provided at the end of the second transfer track 412, and the push plate 443 is connected to the third positioning cylinder 446. The positioning roller 441 and the positioning plate 442 are both provided on the surface of the second transfer track 412, the positioning plate 442 is located between the positioning roller 441 and the push plate 443, and the positioning roller 441 and the positioning plate 442 are connected to the second positioning cylinder 444 and the first positioning cylinder 445, respectively. The positioning roller 441 can be driven by the second positioning cylinder 444 to vertically extend out of the surface of the second transfer track 412, thereby blocking the movement of the product. The surface of the positioning plate 442 is provided with a suction cup (not shown) which can absorb the product and position the product. When the positioning is completed, the positioning plate 442 can be driven by the first positioning cylinder 445 to move vertically downward to release the product. When the product is placed on the positioning plate 442, the push plate 443 can be driven by the third positioning cylinder 446 to extend to both sides of the product, thereby limiting the horizontal direction of the product.

[0032] Please refer to Figure 5The first tensioning unit 42 includes a mounting plate 421, which is vertically arranged, and a cutter 422 for cutting the insulating film is arranged near the lower end of the mounting plate 421. Specifically, a fourth driving member 423 is arranged on the mounting plate 421, and the fourth driving member 423 is connected to the cutter 422. The cutter 422 can move horizontally under the drive of the fourth driving member 423, so as to cut the insulating film in a horizontal direction. A first clamping unit 424 for clamping the insulating film is slidably provided on one side of the mounting plate 421. The first clamping unit 424 includes a cushion block 4241, a fifth driving member 4242, and a fixed plate 4243. The fixed plate 4243 is horizontally arranged. The fifth driving member 4242 is fixed on the fixed plate 4243. The cushion block 4241 is arranged opposite to the mounting plate 421 and connected to the fifth driving member 4242. The fifth driving member 4242 can drive the cushion block 4241 to move horizontally and abut against the surface of the mounting plate 421, thereby clamping the insulating film between the mounting plate 421 and the cushion block 4241. A first pressing roller unit 425 and a second pressing roller unit 426 are provided on both sides below the mounting plate 421. The first pressing roller unit 425 and the second pressing roller unit 426 can move vertically relative to the mounting plate. The first pressing roller unit 425 includes a sixth driving member 4251 and a plurality of first pressing rollers 4252 arranged in parallel. The sixth driving member 4251 can drive the first pressing roller 4252 to move vertically, thereby pressing the product from top to bottom and limiting the moving product. The second pressing roller unit 426 includes a seventh driving member 4261, a horizontal driving cylinder 4263, and a second pressing roller 4262. The seventh driving member 4261 is fixed on the mounting plate 421. The seventh driving member 4261 can drive the second pressing roller 4262 to press the surface of the product from top to bottom, thereby making the insulating film close to the upper surface of the product. The horizontal driving cylinder 4263 is connected to the second pressing roller 4262 and is used to drive the second pressing roller 4262 to move horizontally, thereby rolling the insulating film flat.

[0033] Please refer to Figure 6The second tensioning unit 43 includes a second driving unit 431, and one side of the second driving unit 431 is slidably connected with a second clamping unit 432 for clamping the lower end of the insulating film. The second clamping unit 432 includes a first clamping plate 433, a second clamping plate 434, and an eighth driving member 435. The first clamping plate 433 and the second clamping plate 434 are vertically arranged opposite to each other. The first clamping plate 433 is slidably connected to the second driving unit 431, and the eighth driving member 435 is fixed on one side of the first clamping plate 433. The eighth driving member 435 can drive the second clamping plate 434 to abut against the first clamping plate 433, thereby clamping the lower end of the insulating film. The second clamping unit 432 moves vertically downward along the second driving unit 431, so that the insulating film is vertically tightened. A leveling unit 436 for leveling the insulating film is provided at the upper end of the second driving unit 431. The leveling unit 436 includes a clamping block 437 and a ninth driving member 438. The ninth driving member 438 is fixed at the upper end of the second driving unit 431. The clamping block 437 is made of smooth rubber. The clamping block 437 can extend toward the insulating film under the drive of the ninth driving member 438, and scrape the surface of the insulating film while the second clamping unit 432 pulls out the insulating film to make the surface of the insulating film smooth.

[0034] The working principle of the large film wrapping mechanism 4 is as follows: the insulating film unwinding mechanism 2 unwinds the insulating film to the first tensioning unit 42, at which time the second clamping unit 432 moves upward and clamps the lower end of the insulating film, and then the second clamping unit 432 resets and pulls the insulating film downward, so that the insulating film passes through the avoidance gap 413 from top to bottom and vertically blocks the forward direction of the second transfer track 412, the first clamping unit 424 clamps the insulating film from the upper end, the first tensioning unit 42 cuts the insulating film to separate it from the film material, and at this time the feeding mechanism 1 places the product on the positioning unit 44, the positioning unit 44 The product is positioned, and the clamping unit 414 clamps the product from both sides, and then the positioning unit 44 releases the product. The product moves along the second transfer track 412 under the drive of the clamping unit 414, and the bottom surface of the product facing the front is against the insulating film. At this time, the first tensioning unit 42 and the second tensioning unit 43 release the insulating film, and the clamping unit 414 continues to move. The product drives the insulating film forward, and at the same time, the second pressing roller unit 426 moves downward and presses the insulating film on the upper and lower surfaces of the product, thereby realizing rapid film coating of the bottom, upper and lower surfaces of the product. The large film coating mechanism 4 has an ingenious structure, which effectively simplifies the film coating process and improves the efficiency of film coating.

[0035] Please refer to Figure 7The side film wrapping mechanism 3 includes a positioning seat 31, a third driving unit 32, a bottom angle rolling unit 33, and a side rolling unit 34. The third driving unit 32 is vertically arranged, and the side rolling unit 34 is arranged on the side of the third driving unit 32 facing the large film wrapping unit 4, and the side rolling unit 34 is slidably connected to the third driving unit 32. The side rolling unit 34 includes a bracket 36 and a plurality of side pressing rollers 35. In this embodiment, there are four side pressing rollers 35, which are arranged on both sides of the positioning seat 31 in pairs. The axial direction of the side pressing rollers 35 is horizontal, and the distance between the two side pressing rollers 35 matches the width of the product. The bottom corner rolling unit 33 is arranged at one end of the positioning seat 31 away from the large film wrapping mechanism 4. The bottom corner rolling unit 33 includes two bottom corner pressing rollers 37 arranged opposite to each other and a tenth driving member 38. The bottom corner pressing rollers 37 are connected to the tenth driving member 38. The axial direction of the bottom corner pressing rollers 37 is vertical, and the distance between the two bottom corner pressing rollers 37 matches the width of the product. The bottom corner pressing rollers 37 can move horizontally toward the positioning seat 31 under the drive of the tenth driving member 38. In order to fix the product, a rotating cylinder 39 for pressing and fixing the product is provided on one side of the positioning seat 31.

[0036] The working principle of the side wrapping mechanism 3 is as follows: the product moves from the large wrapping mechanism 4 to the positioning seat 31 of the side wrapping mechanism 3, the rotary cylinder 39 rotates and presses the product, and the bottom corner pressing roller 37 moves horizontally toward the positioning seat 31 under the drive of the tenth driving member 38, thereby folding the insulating film at the bottom corner position of the product to both sides of the product. At this time, the side rolling unit 34 first moves vertically downward, and then moves vertically upward, so that the side pressing roller 35 first rolls the insulating film from top to bottom, and then rolls the insulating film from bottom to top, so that the insulating film is flatly attached to the two sides of the product, effectively improving the quality of the wrapping.

[0037] Please refer to Figure 1 and Figure 8The unloading mechanism 5 includes an unloading manipulator 57 and a third transfer track 51. The unloading manipulator 57 is arranged above the side film coating mechanism 3. The third transfer track 51 is arranged in parallel with the first transfer track 12. One end of the third transfer track 51 is close to the rear end of the unloading manipulator 57. A placement block 52 is slidably arranged on the third transfer track 51. The placement block 52 is provided with a fixing unit 54 for fixing the product. The fixing unit 54 includes a push block 55 and a push block cylinder 56. The push block 55 can push the side of the product under the drive of the push block cylinder 56, and clamp the product between the push block 55 and the side wall of the placement block 52. A code scanning unit 53 is arranged at the rear end of the third transfer track 51. The code scanning unit 53 scans the finished product and enters it into the system. The code scanning unit 53 can specifically use CCD visual detection. In specific implementation, the unloading robot 57 clamps the film-coated product on the positioning seat 31 and moves it to the placement block 52. The placement block 52 moves along the third transfer track 51 and scans the code through the code scanning unit 53, thereby realizing rapid unloading of the product. It should be noted that the unloading robot 57 adopts the same structure as the loading robot 11, which will not be described in detail here.

[0038] The above-mentioned driving member can be a motor or a cylinder, or other commonly used mechanical driving methods, which are not limited here.

[0039] In summary, the present invention realizes automatic film packaging of products, effectively improves the efficiency of product film packaging, and ensures the accuracy and quality of film packaging.
