[0053] Taking the application of the wrapping mechanism provided by an embodiment of the present invention to the wrapping of terminal products as an example, the working principle of a wrapping mechanism provided by an embodiment of the present invention is as follows: first, a protective film 40 is placed on the support table 20, and then the product 50 to be wrapped is placed on the protective film 40; then the translation drive 331 is controlled to drive the crimping part 340 to approach the side wall surface of the terminal product 50 to be wrapped, and then the lifting drive 321 is controlled to drive the crimping part 340 to move along the side wall surface of the terminal product to be wrapped, so that the protective film 40 is adhered to the side wall surface of the product; then, the lifting drive 321 is controlled to drive the crimping part 340 to press the protective film 40 on the edge of the upper surface of the product, and then the translation drive 331 is controlled to drive the crimping part 340 to move along the first direction, so that the protective film 40 is adhered to the upper surface of the product.

[0054] Therefore, compared with the manual wrapping in the prior art, a wrapping mechanism provided in an embodiment of the present invention is applied to the wrapping of terminal products. The lifting drive 321 and the translation drive 331 cooperate with each other to drive the crimping part 340 to wrap the protective film 40 on the side wall and upper surface of the terminal product, thereby realizing automatic wrapping, improving the wrapping efficiency and quality, eliminating the need for manual participation in the wrapping, and reducing labor costs and labor intensity.

[0055] In the embodiment of the present invention, see the attached Figure 1 The base 10 includes a base plate 110 and a vertical plate 120. The lower end of the vertical plate 120 is vertically connected to the base plate 110, and the support platform 20 is provided at the upper end of the vertical plate 120; wherein the vertical plate 120 has at least two and is arranged parallel and spaced along the second direction, such as Figure 1 As shown, OY direction.

[0056] In the embodiment of the present invention, see the attached Figure 3 and Figure 4 The lifting drive member 321 is transmission-connected to the lifting seat 360, and the translation drive member 331 is transmission-connected to the translation seat 332; if the translation drive member 331 is installed on the base 10, the lifting drive member 321 is installed on the translation seat 332, and the crimping portion 340 is provided on the lifting seat 360; or, if the lifting drive member 321 is installed on the base 10, the translation drive member 331 is installed on the lifting seat 360, and the crimping portion 340 is provided on the translation seat 332.

[0057] In the embodiment of the present invention, the lifting drive member 321 includes a cylinder or an electric push rod.

[0058] In the embodiment of the present invention, the translation driving member 331 includes a cylinder, an electric push rod, or a linear module.

[0059] In the embodiment of the present invention, see the attached Figure 3 The linear module includes a motor 332 and a slide rail 333. The motor 332 is transmission-connected to the slide rail 333, and the translation seat 332 is slidingly connected to the slide rail 333. If the translation drive member 331 is installed on the base 10, the slide rail 333 is installed on the base 10; or, if the lifting drive member 321 is installed on the base 10, the slide rail 333 is installed on the lifting seat 360.

[0060] In the embodiment of the present invention, see the attached Figure 1 、 Figure 2 and Figure 4 , the crimping part 340 is connected to the crimping bracket 370; one of the lifting seat 360 and the crimping bracket 370 has a guide hole 371; a buffer assembly 350 is provided between the lifting seat 360 and the crimping bracket 370, and the buffer assembly 350 includes a guide column 351 and a spring (not shown in the figure), one end of the guide column 351 is slidably connected to the guide hole 371, and the other end is fixed to the other of the lifting seat 360 and the crimping bracket 370; the spring is provided between the lifting seat 360 and the crimping bracket 370, and the spring is configured to always have a tendency to drive the crimping part 340 to move in the vertical direction and close to the upper surface of the product 50. Specifically, for example, as shown in the attached Figure 2 As shown, the crimping bracket 370 has a guide hole 371, one end of the guide post 351 is slidably connected to the guide hole 371, and the other end is fixed to the lifting base 360. For another example, the lifting base 360 ​​has a guide hole 371, one end of the guide post 351 is slidably connected to the guide hole, and the other end is fixed to the lifting base 360. This arrangement, on the one hand, allows the crimping portion 340 to adapt to the shape of the upper surface of the product 50, such as the local protrusion; on the other hand, it ensures a certain preload force between the pressing portion 340 and the upper surface of the product 50, thereby ensuring a tight fit between the protective film 40 and the product 50.

[0061] In an embodiment of the present invention, a spring is disposed between the lifting seat 360 and the crimping bracket 370. The specific location of the spring is not limited. For example, the spring may be mounted on the guide post 351. In another example, at least one of the lifting seat 360 and the crimping bracket 370 may be provided with a spring receiving slot, and the spring may be located in the spring receiving slot. In another example, there may be multiple springs, some of which may be mounted on the guide post 351. At least one of the lifting seat 360 and the crimping bracket 370 may be provided with a spring receiving slot, and the remaining springs may be located in the spring receiving slot. This arrangement prevents the spring from tilting and ensures that the spring expands and contracts in the vertical direction.

[0062] In the embodiment of the present invention, a linear bearing seat is fixedly provided on one of the lifting seat 360 and the crimping bracket 370 , and an inner hole of the linear bearing seat forms a guide hole 371 .

[0063] In the embodiment of the present invention, see the attached Figure 2 The buffer assembly 350 further includes a guide rail 352, which is mounted on the lifting seat 360, and the crimping bracket 370 is slidably connected to the guide rail 352 along the vertical direction. Such an arrangement provides support and guidance for the movement of the crimping portion 360 along the vertical direction under the action of the spring.

[0064] In the embodiment of the present invention, see the attached Figure 3 The lifting seat 360 includes a support plate 361 and an adjustment plate 362. The support plate 361 is connected to the lifting drive member 321. The adjustment plate 362 has at least two and can be movably connected to the support plate 361 along the second direction. Figure 3 As shown, there are two adjustment plates 362; in addition, there can also be three, four or other numbers of adjustment plates 362; the crimping parts 340 are respectively provided on the adjustment plates 362; wherein the first direction, the second direction and the vertical direction are perpendicular to each other. With such a configuration, the distance between the adjustment plates 362 is adjustable, so that the distance between the crimping parts 340 is adjustable, thereby adapting to the size of the terminal product along the second direction; and adapting to the structural features of the upper surface of the terminal product. It should be noted that the number of crimping parts 340 and adjustment plates 362 is adapted. Regarding the connection method between the adjustment plate 362 and the support plate 361, a variety of methods can be adopted, as follows:

[0065] The first one, see the attached Figure 3 One of the support plate 361 and the adjustment plate 362 has a guide structure 3621, and the other has a slide groove 3611. The guide structure 3621 is slidably connected to the slide groove 3611 along the second direction, wherein the first direction, the second direction and the vertical direction are perpendicular to each other. Specifically, for example, as shown in the attached Figure 3As shown, the support plate 361 has a guide structure 3621, the adjustment plate 362 has a slide groove 3611, and the guide structure 3621 is slidably connected to the slide groove 3611 along the second direction. For another example, the adjustment plate 362 has a guide structure 3621, the support plate 361 has a slide groove 3611, and the guide structure 3621 is slidably connected to the slide groove 3611 along the second direction.

[0066] The second one, see the attached Figure 3 The support plate 361 is provided with a threaded hole, and the adjustment plate 362 is provided with a strip-shaped adjustment hole 3622. The length direction of the strip-shaped adjustment hole 3622 extends along the second direction. The strip-shaped adjustment hole 3622 and the threaded hole are connected by fasteners.

[0067] The third method is to combine the second method with the first method. The method is not limited to the above three methods, and other methods can also be used as long as the distance between the adjustment plates 362 can be adjusted. This is not limited here.

[0068] In the embodiment of the present invention, the pressing part 340 can be a pressing plate or a pressing roller. For example, the pressing part 340 includes a pressing plate, which is fixed to the power output end of the lifting drive member 321. For another example, see the attached Figure 3 The crimping portion 340 includes a crimping roller pivotally connected to the power output end of the lifting drive member 321 and capable of rolling in a first direction. This configuration allows the crimping roller to roll against the protective film, creating rolling friction between the two. This reduces friction between the crimping roller and the protective film, thereby minimizing wear on the protective film.

[0069] In the embodiment of the present invention, the crimping roller has a foam layer. Due to the characteristics of foam such as elasticity, light weight, quick compression and fixation, ease of use, and reliable performance, the foam layer is provided on the crimping roller. This prevents damage to the end product and protective film during the coating process, and provides a better coating effect and greater stability.

[0070] In the embodiment of the present invention, see the attached Figure 1 A pressing bracket 370 is provided at the power output end of the lifting drive member 321, and a pressing roller is pivotally connected to the pressing bracket 370. There are various ways in which the pressing roller can be pivotally connected to the pressing bracket 370. For example, the pressing bracket 370 is fixedly provided with a rotating shaft, and the pressing roller is pivotally connected to the rotating shaft; or another example is that the pressing bracket 370 is pivotally connected to the rotating shaft, and the pressing roller is fixed to the rotating shaft or pivotally connected to the rotating shaft.

This arrangement achieves the fixation of part of the protective film.

[0072] In the embodiment of the present invention, see the attached Figure 5 The support platform 20 is an H-shaped or U-shaped structure, comprising a first connecting portion 210, a second connecting portion 220, and a supporting portion 230. The first connecting portion 210 and the second connecting portion 220 are disposed opposite each other and fixed to the upper end surface of the vertical plate 120. The ends of the supporting portion 230 are connected to the first connecting portion 210 and the second connecting portion 220, respectively. The supporting portion 230 is used to support the protective film 40 and the product 50. This arrangement achieves the fixation of the support platform 20.

[0073] In the embodiment of the present invention, see the attached Figure 5 The upper end surface of the support portion 230 has an air hole 201, and the air hole 201 is used to vacuum absorb the middle part of the protective film 40; the interior of the support portion 230 has a cavity, which is connected to the air hole 201 and is used to connect the vacuum equipment.

[0074] In the embodiment of the present invention, see the attached Figure 5 The upper end surfaces of the first connecting portion 210 and / or the second connecting portion 220 have air holes 201 for vacuum adsorption of the edges of the protective film 40. The first connecting portion 210 and / or the second connecting portion 220 have cavities within them, which are connected to the air holes 201 and are used to connect to vacuum equipment. This arrangement allows the edges of the protective film 40 to be adsorbed. When wrapping the end product, the first connecting portion 210 and / or the second connecting portion 220 release the vacuum adsorption, and the lifting and translating driving members 321 and 331 cooperate to drive the crimping member 340 to wrap the protective film 40 around the sidewalls and top surface of the end product.

[0075] In the embodiment of the present invention, see the attached Figure 5 The support platform 20 further includes a support block 240, the upper surface of which is flush with the upper surface of the support portion 230. The support block 240 comprises at least two support blocks 240, which are fixed to the first connecting portion 210 and the second connecting portion 220, respectively. The support blocks 240 are located on one side of the support portion 230 along the first direction and spaced apart along the second direction to support the edge of the product 50. This arrangement allows the size of the support blocks 240 to be adjusted based on the size of the end product along the first direction.

[0076] In the embodiment of the present invention, see the attached Figure 8 The first connecting portion 210 and the second connecting portion 220 are both provided with a groove portion 211, each having a threaded hole. The support block 240 is provided with a strip hole 241, the length of which extends along the second direction. The strip hole 241 and the threaded hole are connected by a fastener. This arrangement achieves a fixed connection of the support block 240.

[0077] In the embodiment of the present invention, see the attached Figure 1、 Figure 6 and Figure 7 The film wrapping mechanism further includes a clamping assembly 60, the clamping assembly 60 includes a clamping drive 610 and a clamping portion 620, the clamping portion 620 has at least two and relatively spaced apart arrangements along the second direction, for example, as shown in the attached Figure 6 As shown, there are two clamping parts 620 spaced relative to each other along the second direction. Alternatively, there may be three, four, or another number of clamping parts 620. A clamping driver 610 is mounted on the support platform 20 and is transmission-connected to the clamping parts 620. The clamping driver 610 is configured to adjust the distance between any of the relatively arranged clamping parts 620 so that the clamping parts 620 are respectively clamped to the opposite sidewalls of the product 50. The first direction, the second direction, and the vertical direction are perpendicular to each other. This arrangement allows for positioning and clamping of the end product, preventing movement of the end product during the coating process, which could affect the coating quality.

[0078] In the embodiment of the present invention, see the attached Figure 7 The clamping portion 620 includes a clamping body 621 and a flange 622. The flange 622 protrudes from the side wall of the clamping body 621 along the second direction. A gap is formed between the flange 622 and the support platform 20, and the gap is used to clamp the edge of the product. It should be noted that a U-shaped space is formed between the clamping body 621, the flange 622 and the support platform 20, and the U-shaped space is used to accommodate the edge of the product. With this arrangement, the side wall of the clamping body can abut against the side wall of the product, and the lower surface of the flange can abut against the edge of the upper surface of the product, thereby achieving clamping and limiting of the side wall and upper surface of the product.

[0079] In the embodiment of the present invention, see the attached Figure 6 The clamping sidewall of the clamping body 621 has a contoured structure that matches the side profile of the product. This arrangement increases the contact area with the end product and improves the stability of the clamping.

[0080] In the embodiment of the present invention, see the attached Figure 6 The clamping drive member 610 has at least two and is respectively connected to the clamping portion 620, for example, as shown in the attached Figure 6As shown, there are two clamping drive members 610, each of which is transmission-connected to a clamping portion 620. Alternatively, the number of clamping drive members 610 may be three, four, or another number, with the number of clamping drive members 610 corresponding to the number of clamping portions 620. The clamping drive members 610 are arranged obliquely and spaced relative to each other on the support platform 20, with the extensions of the output axes of any of the relatively arranged clamping drive members 610 intersecting below the support platform 20. With this arrangement, the force applied by the clamping drive members 610 to the end product can be decomposed into a force along the second direction and a force in the vertical direction, i.e., a force perpendicular to the sidewall surface of the end product and a force perpendicular to the top surface of the end product, respectively. This clamps the end product to the support platform 20, thus providing the prerequisite for film encapsulation.

[0081] In the embodiment of the present invention, see the attached Figure 6 and Figure 7 The clamping assembly 60 includes a mounting block 630 having an inclined portion 631 on its upper surface. The inclined portion 631 is fixed to the lower surface of the support platform 20. The clamping driver 610 is mounted on the lower surface of the mounting block 630. The angle between the inclined portion 631 and the lower surface of the mounting block 630 is acute. This arrangement allows the clamping driver 610 to be detachably mounted at an angle.

[0082] In the embodiment of the present invention, see the attached Figure 6 and Figure 8 The clamping assembly 60 includes an adjustment assembly 640, which includes a connecting plate 641 and an adjustment plate 642.

The clamping portion 620 is mounted on the adjustment plate 642. This arrangement allows the adjustment plate 642 to be adjusted based on the size of the end product.

[0083] In the embodiment of the present invention, there are many ways to connect the adjustment plate 642 and the connection plate 641, as follows: Figure 8 As shown, the connecting plate 641 is provided with an adjustment hole 6411, which extends in the direction of the output axis of the clamping drive 610. The adjustment hole 6411 is threadedly connected to an adjustment screw 6413, and the end of the adjustment screw 6413 can abut against the side wall of the adjustment plate 642. In this arrangement, the relative position of the adjustment plate 642 and the connecting plate 641 can be adjusted by adjusting the adjustment screw 6413. For another example, as shown in the attached Figure 9As shown, the upper surface of the adjustment plate 642 is provided with through holes 6421, and there are at least two through holes 6421 and they are spaced apart along the direction of the output axis of the clamping drive 610. The connecting plate 641 is provided with threaded holes, and the through holes 6421 and the threaded holes are connected by fasteners. In this way, the through holes and threaded holes at different positions are connected by fasteners, thereby adjusting the relative position between the adjustment plate 642 and the connecting plate 641. For another example, as shown in the attached Figure 8 As shown, the upper surface of the adjustment plate 642 is provided with a strip-shaped adjustment hole 6422, the length direction of the strip-shaped adjustment hole 6422 extends along the direction of the power output axis of the clamping drive 610, and the connecting plate 641 is provided with a threaded hole, and the strip-shaped adjustment hole 6422 and the threaded hole are connected by fasteners.

[0084] In the embodiment of the present invention, a scale is provided on the adjustment plate 642. This arrangement improves the adjustment accuracy of the adjustment plate 642.

[0085] In the embodiment of the present invention, see the attached Figure 8 One of the connecting plate 641 and the adjusting plate 642 is provided with a guide groove 6423, and the other is provided with a guide portion 6412, which is slidably connected to the guide groove 6423. This arrangement provides a guide for the adjusting plate 642 to slide relative to the connecting plate 641.

[0087] In the embodiment of the present invention, see the attached Figure 8 The vertical plate 120 has an avoidance groove 121 , the opening of the avoidance groove 121 faces the second direction, and the limiting block is fixed on the bottom wall surface of the avoidance groove 121 .

[0088] In the embodiment of the present invention, the membrane assembly 30 has at least two groups, for example, Figure 1 As shown, there are two groups of film assemblies; each group of film assemblies 30 includes a lifting drive member 321, a translation drive member 331 and a crimping portion 340; the crimping portion 340 of at least one group of film assemblies 30 is spaced and arranged in parallel with the crimping portion 340 of at least another group of film assemblies 30 along the first direction; for example, Figure 1 As shown, there are two groups of membrane assemblies 30, wherein the crimping portions 340 of one group of membrane assemblies 30 are spaced apart and arranged in parallel with the crimping portions 340 of the other group of membrane assemblies 30 along the first direction.

[0089] Taking two sets of film coating components 30 as an example, the working principle of a film coating mechanism provided by an embodiment of the present invention is as follows:

[0090] First, the protective film 40 is placed on the support table 20, and the vacuum device is turned on to vacuum-absorb the protective film 40; then, the end product is placed on the protective film 40 on the support table 20; then, the clamping drive 610 is controlled to extend and clamp the edge of the end product;

[0091] Then, the translation drive member 331 of one group of film assemblies 30 is controlled to drive the pressing portion 340 to approach the first side wall surface of the terminal product along the first direction, and then the lifting drive member 321 in the group of film assemblies 30 is controlled to drive the pressing portion 340 to move in the vertical direction, so that the protective film 40 is attached to the first side wall surface of the terminal product; then, the lifting drive member 321 of the group of film assemblies 30 is controlled to drive the pressing portion 340 to press the protective film against the edge of the upper surface of the terminal product, and then the translation drive member 331 of the group of film assemblies 30 is controlled to drive the pressing portion 340 to move in the first direction, so that the protective film 40 is attached to a portion of the upper surface of the terminal product; then, the pressing portion 340 of the group of film assemblies 30 moves in the opposite direction of the first direction to move away from the upper surface of the terminal product;

[0092] Finally, the translation drive member 331 of another group of film components 30 is controlled to drive the crimping part 340 to approach the second side wall surface of the terminal product in the opposite direction of the first direction, wherein the second side wall surface is arranged opposite to the first side wall surface, and then the lifting drive member 321 in the group of film components 30 is controlled to drive the crimping part 340 to move in the vertical direction, thereby attaching the protective film 40 to the second side wall surface of the terminal product; thereafter, the lifting drive member 321 of the group of film components 30 is controlled to drive the crimping part 340 to press the protective film on the edge of the upper surface of the terminal product, and then the translation drive member 331 of the group of film components 30 is controlled to drive the crimping part 340 to move in the opposite direction of the first direction, thereby attaching the protective film 40 to another part of the upper surface of the terminal product. It should be noted that the protective film 40 attached to part of the upper surface of the terminal product and the protective film 40 attached to another part of the upper surface of the terminal product can overlap; thereafter, the crimping part 340 of the group of film components 30 moves along the first direction to move away from the upper surface of the terminal product.

[0093] Therefore, a wrapping mechanism provided in an embodiment of the present invention realizes automatic wrapping of the upper surface and the relative side wall surface of the terminal product by setting at least two groups of wrapping components 30, thereby improving the wrapping efficiency and quality, eliminating the need for manual participation in the wrapping, and reducing labor costs and labor intensity.

[0094] In the embodiment of the present invention, the membrane assembly 30 has at least two groups, for example, Figure 1 As shown, the film-wrapping assembly has two groups; each film-wrapping assembly 30 includes a lifting drive member 321, a translation drive member 331 and a crimping portion 340; the crimping portion 340 has at least two and is spaced apart along the second direction, for example, Figure 1As shown, there are two crimping portions 340 located on the same side of the carrier 20, spaced apart along the second direction. The first direction, the second direction, and the vertical direction are perpendicular to each other. This arrangement allows for at least two crimping portions 340 to be located on the same side of the carrier 20, allowing them to crimp different parts of the end product.

[0095] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the scope defined by the claims.
