[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe 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 creative work are within the scope of protection of the present invention.

[0050] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0051] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0052] The existing laminating method for the microwave control panel box is manual laminating. When laminating, first put two products on the table, then cut them by manual die pulling, and use both hands to stuff the film between the two products from all sides to buckle and press them tightly to complete the wrapping and laminating.

[0053] Since the protective film has poor viscosity and poor product wrapping properties, in order to achieve automatic lamination in the prior art, a high-viscosity film needs to be replaced, which increases the overall cost of lamination and is not conducive to large-scale promotion and use. In addition, since the control box lamination requires two products to be folded in half for wrapping, automated action is difficult to achieve.

[0054] The present invention provides a laminating machine, which improves the automatic laminating operation mode of folding two products in half, thereby reducing the requirement of automatic laminating on the film viscosity.

[0055] See also Figures 1 to 14 In one embodiment of the present invention, the laminating machine 100 includes a film laying mechanism 10, a material taking mechanism 20 and a film laminating mechanism 30; the film laying mechanism 10 is used to spread the film toward the first position, and after the film is spread to the first position, the film is cut at the second position to form a film 400 to be coated between the first position and the second position, the material taking mechanism 20 is used to pick up and release the product, and the film laminating mechanism 30 is used to cover the film 400 to be coated on the first product 200 and the second product 300;

[0056] The laminating machine 100 has a first working state and a second working state;

[0057] When the laminating machine is in the first working state, the material taking mechanism 20 is used to place the front side of the first product 200 on the film to be coated 400, and the laminating mechanism 30 is used to stack a part of the film to be coated 400 on the back side of the first product 200, so as to coat part of the surface of the first product and form a film layer on the back side of the first product 200;

[0058] When the laminating machine is in the second working state, the material taking mechanism 20 is used to place the back side of the second product 300 on the film layer, and the laminating mechanism 30 is used to cover the other part of the film 400 to be coated on the front side of the second product 300, so as to laminate the remaining surfaces of the first product and the second product.

[0059] In the present invention, the first product 200 and the second product 300 may be the same product, for example, the first product 200 and the second product 300 may be a control panel box of a microwave oven, the back of the first product 200 may be a non-appearance surface of the first product 200, the remaining several side surfaces of the first product 200, and the front of the first product 200 may be an appearance surface of the first product 200, and the same is true for the second product 300. When the laminating machine 100 of the present invention is in operation, it is used to laminate the appearance surfaces of the first product 200 and the second product 300 to prevent the appearance surfaces of the first product 200 and the second product 300 from being damaged during transportation.

[0060] Alternatively, the first product 200 and the second product 300 may be different products. For example, the first product 200 and the second product 300 may be part structures that need to be assembled in pairs, and the specific details are not limited thereto.

[0061] The first position is arranged opposite to the second position. In the present invention, a working platform 50 is also included. The film laying mechanism 10, the material taking mechanism 20 and the film coating mechanism 30 are all arranged on the working platform 50. A material rack 60 is also arranged on the working platform 50. The material rack 60 is used to install a film roll. The film roll is used to wind the film used for coating by the film coating machine 100. The film roll is arranged at a portion of the working platform 50 close to the second position. When the film coating machine 100 is working, the film laying mechanism 10 clamps the free end of the film wound on the film roll and pulls the film to move toward the first position. When the free end of the film is pulled to the first position, the film covers the working platform 50 from the first position to the second position. At this time, the film is cut off from the second position by the film laying mechanism 10, so that the laid film is separated from the film roll to form a film 400 to be coated. At this time, the first product 200 is placed on the film 400 to be coated by the material picking mechanism 20. When the first product 200 is placed on the film 400 to be coated, the outer side of the film 400 to be coated is exposed compared to the first product 200. At this time, the coating mechanism 30 can be used to stack one or more of the multiple exposed outer sides of the film 400 to be coated toward the back of the first product 200. When stacking toward the back of the first product 200, a coating can be formed on multiple side surfaces of the first product 200. When coating the side of the first product 200, the excess part can be stacked on the back of the first product 200 to form a film layer. At this time, the back of the second product 300 can be placed on the film layer by the material picking mechanism 20, and the film layer can be pressed between the first product 200 and the second product 300 by the weight of the second product 300. The film layer is pressed and positioned to prevent the side coating of the first product 200 from loosening and failing to effectively coat the side of the first product 200. Finally, the laminating mechanism 30 is used to cover the remaining outer edge of the film 400 to be coated toward the second product, the side of the first product 200 facing the remaining part of the film 400 to be coated is coated, and the second product 300 is coated, thereby completing the overall coverage of the first product 200 and the second product 300.

[0062] The laminating machine of the present invention can be applied to a laminating production line, wherein the laminating production line at least includes a manipulator and a material conveying structure, the material conveying structure is used to convey a first product and a second product, the manipulator is used to grab products from the material conveying structure, and is used to feed products to the laminating machine.

[0063] The film laying mechanism 10 at least includes a film pulling component 13 and a cutting component 12. The film pulling component 13 is used to pull the free end of the film toward the first position so that the film can be laid between the first position and the second position. The cutting component 12 is used to cut off the film from the second position after the film is pulled out to the specified position, so as to separate it from the film roll. The material taking mechanism 20 at least includes a movable component and a clamping component 21. The clamping component 21 is used to grab the first product 200 or the second product 300 provided by the manipulator, and is used to put the first product 200 or the second product 300 on the working platform 50. The movable component is used to drive the clamping component 21 to move, so that the clamping component 21 can move toward the film 400 to be coated after clamping the first product 200 or the second product 300. Among them, four laminating mechanisms 30 can be set and are respectively located on the four sides of the first product 200. During lamination, one, two or three of the laminating mechanisms 30 are used to stack one, two or three sides of the film 400 to be coated on the back of the first product 200 to form a coating on multiple sides of the first product 200, and the back of the second product 300 is placed on the back of the first product 200 to form a film layer. The remaining sides corresponding to the film 400 to be coated are covered toward the second product 300 through the remaining laminating mechanisms 30, so that the film 400 to be coated is coated on the remaining sides of the first product 200 and the second product 300.

[0064] The technical solution of the present invention is to set a film laying mechanism 10 to spread the film to form a film to be coated 400 located between the first position and the second position, and to set a material taking mechanism 20. When the laminating machine 100 is in the first working state, the front side of the first product 200 is placed on the film to be coated 400 by the material taking mechanism 20, and a part of the film to be coated 400 is stacked on the back side of the first product 200 by the laminating mechanism 30, so as to coat part of the surface of the first product. When the laminating machine 100 is in the second working state, the material taking mechanism 20 is used to stack the film to be coated 400 on the back side of the first product 200. 0 The second product 300 is placed on the thin film layer stacked on the back of the first product 200, and the second product 300 is used to press the thin film layer to prevent the film on the first product 200 from loosening, and the remaining part of the film 400 to be coated is covered toward the second product 300 through the laminating mechanism 30, and the remaining surface of the first product 200 and the second product 300 are laminated to complete the covering of the entire product, which can improve the working efficiency of the stacked lamination, and at the same time, the product's own weight can be used to achieve the adhesion of the film on the product, reducing the dependence on the film's own viscosity.

[0065] The specific structure of the film laying mechanism 10 is introduced below.

[0066] See also Figure 2 , Figure 3 , Figure 4As shown, the film laying mechanism 10 includes a clamping assembly 11, a cutting assembly 12 and a film pulling assembly 13. The clamping assembly 11 and the cutting assembly 12 are arranged at the second position. The film pulling assembly 13 is used to pull the film from the second position to the first position along the first direction. The clamping assembly 11 is used to clamp the film at the second position, and the cutting assembly 12 is used to cut the film at the second position.

[0067] The film-pulling assembly 13 can be provided in two groups, and the two groups of film-pulling assemblies 13 are respectively provided on both sides of the pressing assembly 11 and can move between the first position and the second position, so that the film can be pulled from the second position to the first position, so that the film is spread between the first position and the second position. In the present invention, since the film itself has elasticity, when the film is cut by the cutting assembly 12, the film will be difficult to cut due to its own elasticity. For this reason, the pressing assembly 11 is provided to press the film at the second position, and the part of the film wound on the film roll can be tightened by the material rack 60, so that the film can be effectively cut at the second position, avoiding the situation where the film cut is uneven or even cannot be cut due to the elasticity of the film itself.

[0068] In addition, since the film itself is elastic, when the film is cut from the second position, in order to prevent one end of the film connected to the film roll from rebounding to the film roll due to its own elasticity when being tightened and cut, resulting in the subsequent film pulling component 13 being unable to pull out the film, the present invention uses the pressing component 11 to press both ends of the film that have been cut, see Figure 3 , Figure 4 As shown, in one embodiment, the clamping assembly 11 includes a first clamping member 111 and a second clamping member 112 spaced apart along a first direction, a cutting space is formed between the first clamping member 111 and the second clamping member 112, the cutting assembly 12 is arranged in the cutting space, and the first clamping member 111 and the second clamping member 112 are respectively used to clamp the film on both sides of the cutting space.

[0069] With such arrangement, when the cutting assembly 12 cuts the film in the cutting space, the films on both sides of the cutting space are fixed, thereby preventing the film near one end of the film roll from rebounding after the film is cut. In addition, the first pressing member 111 and the second pressing member 112 respectively press the films on both sides of the cutting space, so that when the film is cut, the film can be better fixed, preventing the film from slipping due to rebound when it is cut.

[0070] Wherein, the first pressing member 111 can be set as the first driving cylinder 111a and the first pressing plate 111b, the first driving cylinder 111a drives the first pressing plate 111b to rise and fall back and forth to loosen or compress the film, and the second pressing member 112 can be set as the second driving cylinder 112a and the second pressing plate 112b, the second driving cylinder 112a drives the second pressing plate 112b to rise and fall back and forth to loosen or compress the film. The first pressing member 111 can be set on the side of the cutting space away from the film roll, and the second pressing member 112 can be set on the side of the cutting space close to the film roll. In addition, the pressing assembly 11 also includes a first pressing platform 113 and a second pressing platform 114, the first pressing platform 113 is set directly below the first pressing plate 111b, used to cooperate with the first pressing plate 111b to compress the film, and the second pressing platform 114 is set directly below the second pressing plate 112b, used to cooperate with the second pressing plate 112b to compress the film.

[0071] When the film 400 to be coated is covered on the second product 300, since the second product 300 is stacked on the first product 200, the thickness of the first product 200 and the second product 300 after stacking is thicker than the first product 200 itself. When the remaining part of the film 400 to be coated is covered on the top of the second product 300, the remaining part of the film 400 to be coated requires a larger coverage area. For this reason, it is necessary to make the length of the part of the film 400 to be coated covering the second product 300 greater than the thickness of the film 400 to be coated covering the first product 200. This can be achieved by pulling the film 400 to be coated toward one side so that when the first product 200 is placed on the film 400 to be coated, the film 400 to be coated parts on both sides of the first product 200 have unequal widths. The relevant settings are as follows: optionally, the first clamping member 111 is used to loosen the film 400 to be coated when the film 400 to be coated is formed, and the film pulling assembly 13 is used to pull the end of the film to be coated located at the first position to a third position when the first clamping member 111 loosens the film 400 to be coated, wherein the third position is located on the side of the first position away from the second position.

[0072] With such arrangement, after the film 400 to be coated is formed, it can be moved in a direction away from the second position by the film pulling assembly 13, so that the first product 200 is placed on the film 400 to be coated, and the films 400 to be coated on both sides of the first product 200 are designed with different widths. This facilitates the remaining part of the film 400 to be coated to completely cover the top of the second product 300. And when the first pressing member 111 releases the film 400 to be coated, the second pressing member 112 can always be in a state of pressing the film on the film roll.

[0073] See also Figure 2As shown, in one embodiment, the film-pulling assembly 13 is provided with two, and the two film-pulling assemblies 13 are arranged on both sides of the film 400 to be coated along the second direction, and the film-pulling assembly 13 includes a track member 131, a linear driving member 132 and a clamping member 133, the track member 131 is extended along the first direction, the clamping member 133 is arranged on the track member 131, the clamping member 133 is used to clamp the film, and the linear driving member 132 is used to drive the clamping member 133 to move along the track member 131 to drive the film to move, wherein the first direction and the second direction are cross-arranged.

[0074] In the above embodiment, the linear drive member 132 includes a first drive motor, a first transmission belt and a first mounting base, the first mounting base is slidably mounted on the track member 131, and the first mounting base is mounted with a clamping member 133, wherein the clamping member 133 may include two first clamping jaws spaced apart in the height direction, and a clamping cylinder driving the two first clamping jaws to move closer to or farther from each other. The first transmission belt is extended along the first direction and arranged on the track member 131, the first mounting base is connected to the transmission belt, the first drive motor drives the transmission belt to move, so as to drive the first mounting base to move on the track member 131, thereby driving the clamping member 133 to move along the first direction, when the clamping member 133 moves along the first direction to the second position, it can clamp the free end of the film arranged on the film roll, under the drive of the first drive motor, the clamping member 133 can move toward the first position along the first direction, and lay the film between the first position and the second position, so as to facilitate the formation of the film 400 to be coated.

[0075] Since the first product 200 is placed on the film 400 to be coated, when the film 400 to be coated is pushed to the top of the first product 200 (the back of the first product 200), the portion of the film 400 to be coated that is used to cover the first product 200 needs to be higher than the portion of the top of the first product 200 (the back of the first product 200), so that the film 400 to be coated can be pushed to the top of the first product 200, and when the film 400 to be coated is pushed to the top of the second product 300, the portion of the film 400 to be coated that is used to cover the second product 300 needs to be higher than the portion of the top of the second product 300 (the front of the second product 300). To this end, a corresponding lifting structure can be set to lift the first product 200 and the second product 300, so that the remaining portion of the film 400 to be coated can be higher than the portion of the top of the first product 200 (the back of the first product 200), and the portion of the film 400 to be coated can be higher than the portion of the top of the second product 300 (the front of the second product 300). The relevant settings are as follows.

[0076] See also Figure 7 , Fig.10 , Fig.14As shown, in one embodiment, the laminating mechanism 30 includes a positioning assembly 40 and a frame 31, the positioning assembly 40 is arranged on the frame 31, the positioning assembly 40 includes a support member 41 and a first driving member 42 drivingly connected to the support member 41, the first driving member 42 is used to drive the support member 41 to rise and fall, and the support member 41 is used to place the first product 200 and the second product 300.

[0077] In the present invention, when the laminating machine 100 is in the first working state, the first driving member 42 is used to drive the supporting member 41 to descend, so as to drive the first product 200 to descend. When the laminating machine 100 is in the second working state, the first driving member 42 is used to drive the supporting member 41 to descend, so as to drive the first product 200 and the second product 300 to descend.

[0078] The first driving member 42 can be set as a lifting cylinder structure or a servo motor and screw structure. The positioning assembly 40 can be set in the middle of the frame 31. When the laminating machine 100 is in the first working state, it can drive the first product 200 to descend, so that the top height of the first product 200 can be lower than the height of the part of the film 400 to be coated on the first product 200, so that the laminating mechanism 30 can cover the part of the film 400 to be coated on the first product 200 to the first product 200, and can drive the first product 200 and the second product 300 to descend at the same time, so that the top height of the second product 300 (the front of the second product 300) is lower than the height of the part of the film 400 to be coated on the second product 300, so that the laminating mechanism 30 can cover the part of the film 400 to be coated on the second product 300 to the second product 300, so as to achieve coverage of the entire product, without the need to raise the laminating mechanism 30 as a whole, and the operation is simpler.

[0079] The following is a description of how the laminating mechanism 30 specifically performs the laminating operation. Figure 6 , Figure 7 , Figure 8 As shown, in one embodiment, the laminating mechanism 30 also includes a first laminating component 32 arranged on the frame 31, and the first laminating component 32 is arranged on the side of the positioning component 40 close to the second position. When the laminating machine is in the first working state, the first laminating component 32 is used to laminar the first side of the first product 200.

[0080] The first side surface may be the side of the first product 200 facing the second position. With such a configuration, the laminating operation on the first side surface of the first product 200 can be realized by an independent laminating assembly, thereby realizing a more accurate laminating operation for the first product 200. The first laminating assembly 32 may be realized by clamping the side of the film 400 to be coated close to the second position and then moving it toward the top of the second product 300. Alternatively, the first laminating assembly 32 may be located at the bottom of the film 400 to be coated, and the laminating operation on the first side surface of the first product 200 may be realized by pushing the film 400 to be coated toward the back of the first product 200 and stacking it. The specific details are not limited.

[0081] See also Figure 6 , Figure 8 As shown, in one embodiment, the first laminating assembly 32 includes a second driving member 321 and a first film pushing plate 322, the second driving member 321 is used to drive the first film pushing plate 322 to approach or move away from the first product 200 along a first direction, and when the laminating machine is in a first working state, the first film pushing plate 322 is used to stack the side of the film 400 to be coated close to the second position on the back of the first product 200, so that the film 400 to be coated can be coated on the first side of the first product 200.

[0082] The first film coating assembly 32 further includes a first sliding seat 323 and a first slide rail 324. The first sliding seat 323 is slidably disposed on the first slide rail 324 along a first direction. The first film pushing plate 322 is disposed on the first sliding seat 323. The second driving member 321 may include a second driving motor 3211 and a second transmission belt 3212. The first sliding seat 323 is connected to the second transmission belt 3212. The second driving member 321 is used to drive the second transmission belt 3212 to move, so as to drive the first sliding seat 323 to slide on the first slide rail 324, thereby making the first film pushing plate 322 The film plate 322 can move toward the first product 200. Since the first film pushing plate 322 is located at the bottom of the film 400 to be coated, when the first product 200 is driven by the positioning component 40 and descends to the back side of the first product 200 (located at the top of the first product 200) and is under the first film pushing plate 322, the film 400 to be coated is pushed toward the first product and folded at the position of the first side surface of the first product 200 and the back side of the first product 200, so that the film 400 to be coated can be stacked on the back side of the first product 200, thereby forming a coating on the first side surface.

[0083] And after the first film pushing plate 322 completes film pushing, the first film pushing plate 322 can pre-press the part of the film 400 to be coated stacked on the back of the first product 200, so that the film layer can be pre-positioned on the first product 200. After the second product 300 is placed on the first film pushing plate 322, when the first film pushing plate 322 moves in a direction away from the first product 200, the second product 300 can naturally fall and be pressed on the film layer, preventing the film on the first side of the first product 200 from loosening.

[0084] See also Figure 6 , Figure 7 , Figure 8 As shown, in one embodiment, the laminating mechanism 30 also includes a second laminating assembly 33 arranged on the frame 31, and when the laminating machine is in a first working state, the second laminating assembly 33 is used to laminar the two second side surfaces of the first product 200 along a second direction, wherein the first direction and the second direction are cross-arranged.

[0085] In the present invention, the second direction may be the front-to-back direction. With such a configuration, when the laminating machine 100 is in the first working state, the films 400 to be coated located on the front and back sides of the first product 200 are stacked toward the back of the first product 200, and the front and back second sides of the first product 200 are coated. Since the front and back sides of the film 400 to be coated are relatively narrow, after the film 400 to be coated is coated on the two second sides of the first product 200, the film layer stacked on the back of the first product 200 can be pressed by the second product 300 to ensure that the films formed on the two second sides of the first product 200 will not spread, and to avoid the film 400 to be coated being relatively narrow on the front and back sides, and having poor adhesion and becoming loose when it is covered on the first product 200.

[0086] Continue reading Figure 6 , Figure 7 , Figure 8 In one embodiment, the second film coating assembly 33 includes a third driving member 331 and two second film pushing plates 332, and the two second film pushing plates 332 are respectively arranged on both sides of the positioning assembly 40 along the second direction. The third driving member 331 is used to drive the two second film pushing plates 332 to move closer to or away from the first product 200 along the second direction. When moving closer to the first product 200, the second film pushing plates 332 are used to stack the film 400 to be coated on both sides of the support member 41 along the second direction on the back of the first product 200, so that the film 400 to be coated can form a coating on the two second side surfaces of the first product 200 opposite to each other along the second direction.

[0087] The second film coating assembly 33 further includes two sets of second sliding seats 333 and second slide rails 334 arranged oppositely. The second sliding seats 333 are slidably arranged on the second slide rails 334 along the second direction. The two second film pushing plates 332 are respectively arranged on the corresponding second sliding seats 333. The third driving member 331 may include a third driving motor 3311 and a third transmission belt 3312. The third transmission belt 3312 has two transmission parts arranged oppositely. The two transmission parts can approach or move away from each other when the third transmission belt 3312 moves. The two second sliding seats 333 are respectively connected to the two transmission parts. The third driving motor 3311 is used to drive the third transmission belt 3312 to move. The two second sliding seats 333 are driven to move toward or away from the first product 200 on the corresponding second slide rail members 334, so that the second film pushing plate 332 can move toward the first product 200. Since the second film pushing plate 332 is located at the bottom of the film 400 to be coated, the positioning assembly 40 can drive the first product 200 to descend, so that the back side of the first product 200 (located at the top of the first product 200) is under the second film pushing plate 332, and the film 400 to be coated is pushed toward the first product 200, and the film 400 to be coated is stacked on the back side of the first product 200 (located at the top of the first product 200), forming a coating on two oppositely arranged second side surfaces of the first product 200.

[0088] And when the second film pushing plate 332 stacks the film 400 to be coated on the back of the first product 200, the second film pushing plate 332 can pre-press the film stacked on the back of the first product 200, so that the film layer formed on the back of the first product 200 (located on the top of the first product 200) can be pre-positioned on the first product 200. After the second product 300 is placed on the second film pushing plate 332, when the second film pushing plate 332 moves in a direction away from the first product 200, the second product 300 can naturally fall and be pressed on the film layer, ensuring that the coating formed on the two second side surfaces of the first product 200 does not loosen.

[0089] Continue reading Figure 6 , Figure 7 , Figure 8 In one embodiment, the third driving member 331 includes a third driving motor 3311 and a third transmission belt 3312, the third transmission belt 3312 has a first transmission part 3312a and a second transmission part 3312b that are relatively arranged, and the two second push film plates 332 are detachably connected to the first transmission part 3312a and the second transmission part 3312b, respectively. The third driving motor 3311 is used to drive the third transmission belt 3312 to move so that the two second push film plates 332 are close to each other or away from each other.

[0090] The first transmission part 3312a and the second transmission part 3312b may be two belt parts of the third transmission belt 3312 that are arranged opposite to each other. Since the two second film pushing plates 332 are detachably connected to the two belt parts, the two second film pushing plates 332 can be adjusted to the installation positions of the two belt parts. For example, when the second film pushing plates 332 are installed to the belt part at a position away from the positioning assembly 40, the film pushing stroke of the second film pushing plates 332 is longer, and a wider film 400 to be coated can be covered on the first product 200. Thus, the laminating mechanism 30 can adapt to the laminating operation of films of different widths.

[0091] In one embodiment, the film laminating mechanism 30 further includes a positioning member 35, a plurality of the positioning members 35 are provided, and the positioning members 35 are spaced apart around the frame 31, and the top surface height of the positioning member 35 is lower than the top height of the first film pushing plate 322 and the second film pushing plate 332, and the positioning member 35 is used to place the film to be coated 400. In this way, when the film laminating mechanism 30 is laminating toward the first product 200, the positioning member 35 can support and position the film to be coated 400.

[0092] After the lamination of part of the appearance surface of the first product 200 is completed and the second product 300 is placed on the film layer, the remaining part of the film 400 to be coated needs to be covered toward the second product 300 to complete the lamination operation of the remaining appearance part of the first product 200 and the second product 300. Fig.10 , Fig.14 As shown, in one embodiment, the laminating mechanism 30 also includes a third laminating component 34, and the third laminating component 34 is arranged on the side of the film 400 to be coated away from the second position. When the laminating machine is in the second working state, the third laminating component 34 is used to laminar the third side of the first product 200 and the second product 300.

[0093] In this way, the laminating operation on the remaining appearance surface of the first product 200 and the second product 300 can be completed by operating independent laminating components, without moving the first laminating component 32 or the second laminating component 33 as a whole toward the first position. It is achieved by operating the first laminating component 32 and the second laminating component 33, which makes the operation of the entire laminating mechanism 30 simpler and the laminating efficiency higher.

[0094] The specific structure of the third film covering component 34 is introduced below. Fig.10 , Fig.14As shown, the third coating assembly 34 includes a placement plate 341, a roller 342 and a fourth driving member 343, the placement plate 341 is used to place the side of the film 400 to be coated away from the second position, the roller 342 is arranged on the side of the placement plate 341 close to the second position, and the fourth driving member 343 is used to drive the roller 342 to move toward the second product 300, so as to push the side of the film 400 to be coated away from the second position toward the front of the second product 300, so that the film 400 to be coated forms a coating on the second product 300 and the third side of the first product 200.

[0095] The placement plate 341 is used to place the side of the film 400 to be coated close to the second position to support the film 400 to be coated. The third coating assembly 34 also includes a coating frame 344 and two guide rods 345. The placement plate 341, the guide rods 345 and the fourth driving member 343 are all installed on the coating frame 344. The guide rods 345 are connected to the rollers 342, and the guide rods 345 are in transmission connection with the fourth driving member 343. The fourth driving member 343 drives the guide rods 345 to move toward or away from the second position, so that the guide rods 345 extend or retract to both sides of the placement plate 341, thereby driving the rollers 342 to move toward or away from the second position.

[0096] With such arrangement, the roller 342 can be driven by the fourth driving member 343 to move toward the second product 300. Since the roller 342 and the placement plate 341 are located below the film 400 to be coated, when the second product 300 is driven to descend by the positioning assembly 40 so that the front side of the second product 300 (located on the top of the second product 300) is below the roller 342, the remaining part of the film 400 to be coated can be pushed toward the front side of the second product 300 (located on the top of the second product 300), so that the film 400 to be coated is folded in half at the front side of the second product 300 and the side position close to the second position, and covered on the second product 300, thereby realizing the lamination operation on the second side (the side close to the second position) of the first product 200 and the second product 300. In addition, after the third laminating assembly 34 completes laminating on the second product 300, the film 400 to be coated is located below the roller 342 and the placement plate 341, and the first driving member 42 can drive the support member 41 to rise to eject the laminated first product 200 and the second product 300. When the laminated products rise from the opening formed by the roller 342, the two guide rods 345 and the placement plate 341, the two guide rods 345, the placement plate 341 and the roller 341 press the outer peripheral part of the film 400 to be coated covering the front part of the second product 300 downwards, so as to fit the side of the second product 300 and cover the entire product.

[0097] See also Fig.10As shown, in one embodiment, the third laminating assembly 34 further includes a lifting cylinder 346, and the lifting cylinder 346 drives the connected laminating frame 344 to rise or fall, so as to drive the placement plate 341 and the roller 342 to rise or fall synchronously.

[0098] With such arrangement, when the positioning assembly 40 fails to drive the second product 300 to descend sufficiently, causing the top of the second product 300 to be unable to be located below the roller 342, the lifting cylinder 346 can be used to drive the roller 342 and the placement plate 341 to be lifted as a whole, so that the roller 342 can be located above the top of the second product 300.

[0099] See also Figure 5 As shown, in one embodiment, the material picking mechanism 20 includes a clamping assembly 21 and a flipping drive 22, wherein the clamping assembly 21 is used to clamp or release the product, and the flipping drive 22 is used to drive the clamping assembly 21 to flip, so that the product clamped by the clamping assembly 21 can be flipped 180°.

[0100] The material taking mechanism 20 further comprises a material taking frame 24 and a material taking and placing cylinder 23. The clamping assembly 21, the material taking and placing cylinder 23 and the flipping driving member 22 are arranged on the material taking frame 24. The flipping driving member 22 is used to drive the clamping assembly 21 to flip. The material taking and placing cylinder 23 is used to drive the clamping assembly 21 and the flipping driving member 22 to rise and fall simultaneously, so that the clamping assembly 21 can place the first product 200 on the film 400 to be coated with the front side facing the film 400 after clamping the first product 200, and place the second product 300 on the film 400 to be coated with the back side facing the film 400 after clamping the second product 300. The clamping assembly 21 comprises two second clamping jaws 211 arranged opposite to each other and a clamping driving member 212 driving the two second clamping jaws 211 to move closer to or away from each other.

[0101] In the present invention, the first product 200 and the second product 300 may be control panel boxes of microwave ovens. To prevent the appearance surface of the control panel box of the microwave oven from being scratched by the non-appearance surface (installation portion) of another control panel box during film coating, when the two microwave oven control panel boxes are stacked for film coating, the front of the control panel box needs to face outwards, and the backs of the two control panel boxes need to face inwards and be placed opposite to each other. To this end, by providing a flip driving member 22 for the material taking mechanism 20, the clamping assembly 21 can be flipped 180 degrees after clamping the first product 200, so that the display portion of the first product 200 faces the film to be coated 400, thereby preventing the installation portion of the first product 200 from scratching the film to be coated 400, and preventing the display portion of the first product 200 from being scratched.

[0102] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
