[0046] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the invention can be combined interchangeably without conflicting with each other.

[0047] like Figure 1 As shown, a fixed-length laminating and folding device comprises a material discharging mechanism 1, a clamping mechanism 2, a cutting mechanism 3, and a second folding and turning mechanism 4;

[0048] The material discharging mechanism 1 is used to supply materials;

[0049] The clamping mechanism 2 includes a bare piece clamping module 21 and a material clamping module 22. The bare piece clamping module 21 is used to clamp the piece to be coated 61, and the material clamping module 22 is used to clamp the material supplied by the material discharge mechanism 1. The material clamping module 22 clamps the material and moves relative to the piece to be coated 61 on the bare piece clamping module 21, and the material is coated on the surface of the piece to be coated 61 to form a coated piece 62.

[0050] A cutting mechanism 3, used for cutting the material coated on the outer surface of the coated part 62;

[0051] The second folding and turning mechanism 4 includes an object clamping module 41 and a folding module 42 . The object clamping module 41 is used to clamp the wrapped piece 62 , and the folding module 42 is used to turn and fold the material on the wrapped piece 62 .

[0052] The working process of the device is as follows: the discharge mechanism 1 supplies the material to the clamping mechanism 2, the clamping module 22 on the clamping mechanism 2 clamps the material, and the bare part clamping module 21 clamping the part to be coated 61 moves toward the material, and coats the material on the surface of the part to be coated 61 to form a coated part 62, completing the coating step; then, the cutting mechanism 3 cuts the material on the outer surface of the coated part 62, and releases the connection between the material on the coated part 62 and the material on the discharge mechanism 1, and then the object clamping module 41 on the second folding and flipping mechanism 4 clamps the coated part 62 from the bare part clamping module 21, and the object clamping module 41 drives the coated part 62 to rotate toward the folding module 42, so that the folding module 42 is offset against the material on the coated part 62, completing the folding step; the above-mentioned whole process does not require manual participation, and is all mechanically operated with a high degree of automation, which can reduce the manual production cost of the coating and folding steps, improve production efficiency, and improve the consistency of coating.

[0053] Furthermore, the material is a coating roll 7. In an initial state, the material clamping module 22 clamps a first free end (not shown in the figure) of the coating roll 7. After the cutting mechanism 3 cuts the material on the outer surface of the coated part 62, the material is broken into two parts to form a second free end (not shown in the figure) and a new first free end (not shown in the figure). The object clamping module 41 clamps the side of the coated part 62 that is away from the first free end and the second free end. At this time, the first free end and the second free end are away from the object clamping module 41. The folding module 42 abuts against the first free end and the second free end to fit the first free end and the second free end to the outside of the coated part 62, thereby completing the folding step with a high degree of automation.

[0054] Furthermore, it also includes a material pushing mechanism 5, which is retractably arranged on one side of the clamping mechanism 2. When the material pushing mechanism 5 is extended, it is used to press the material on the wrapped part 62 on the clamping mechanism 2 for cutting by the cutting mechanism 3;

[0055] like Figure 1 As shown, further, the clamping mechanism 2 is provided with a first rotation center 20, and the bare part clamping module 21 and the material clamping module 22 rotate around the first rotation center 20; specifically, the bare part clamping module 21 drives the part to be coated 61 to rotate toward the material clamping module 22 clamping the material, so as to cover the outer surface of the part to be coated 61 with the material.

[0056] Specifically, the second folding and flipping mechanism 4 is provided with a second rotation center 40, the object clamping module 41 rotates around the second rotation center 40, the folding module 42 is fixedly arranged on one side of the second rotation center 40, the object clamping module 41 clamps the wrapped part 62 and moves to the bottom of the folding module 42, the folding module 42 abuts against the material on the wrapped part 62, and flips and folds the material. Figure 2 In the present embodiment, the clamping mechanism 2 rotates clockwise around the first rotation center 20 , and the object clamping module 41 rotates counterclockwise around the second rotation center 40 .

[0057] Specifically, the number of the object clamping modules 41 and the bare component clamping modules 21 is the same, and the object clamping modules 41 are evenly distributed along the circumference of the clamping mechanism 2, and the bare component clamping modules 21 are evenly distributed along the circumference of the second folding and flipping mechanism 4;

[0058] The angular velocity of the clamping mechanism 2 is the same as that of the second folding and turning mechanism 4. In this way, when the coated part 62 is initially formed, the object clamping module 41 intersects with the bare part clamping module 21 clamping the coated part 62, so that the object clamping module 41 clamps the coated part 62 and enters the folding step, thereby improving processing efficiency.

[0059] like Figure 1 As shown, more specifically, there are four bare part clamping modules 21 and four material clamping modules 22, which are evenly distributed on four workstations of the clamping mechanism 2 at 90 degrees apart; there are also four object clamping modules 41, which are evenly distributed on four workstations of the second folding and flipping mechanism 4 at 90 degrees apart.

[0060] like Figure 1-2 As shown, further, the material discharging mechanism 1 is arranged below the clamping mechanism 2; the second folding and turning mechanism 4 is arranged on one side of the clamping mechanism 2; and the cutting mechanism 3 is arranged between the material discharging mechanism 1 and the second folding and turning mechanism 4. After the clamping mechanism 2 clamps the material supplied by the adjacent material discharging mechanism 1, it rotates 180° to cover the material on the outer surface of the to-be-covered piece 61; the compact design among the material discharging mechanism 1, the clamping mechanism 2, the cutting mechanism 3 and the second folding and turning mechanism 4 can ensure that the to-be-covered piece 61 is covered within the shortest length of the material, which can save the floor space of the device.

[0061] like Figure 5-6 As shown, specifically, the material pushing mechanism 5 is arranged between the material unloading mechanism 1 and the second folding and turning mechanism 4. Specifically, as Figure 1-2As shown, the pushing mechanism 5 is coaxial with the cutting mechanism 3 and is arranged radially along the clamping mechanism 2, and the pushing mechanism 5 is arranged on a side close to the clamping mechanism 2; in this way, the compactness of the device is further improved and the floor space is reduced.

[0062] like Figure 6 , 9 As shown, further, the clamping module 22 includes a clamping group 221, and the clamping group 221 includes a fixed block 221-1, a clamping driving member 221-2, and a moving block 221-3 provided at the output end of the clamping driving member 221-2; the clamping driving member 221-2 drives the moving block 221-3 to extend and retract relative to the fixed block 221-1, and a clamping station 221-4 is provided between the fixed block 221-1 and the moving block 221-3. When in use, the clamping driving member 221-2 drives the moving block 221-3 to move toward the fixed block 221-1 to close the clamping station 221-4, thereby clamping the material in the clamping station 221-4.

[0063] More specifically, the fixed block 221-1 and the movable block 221-3 are axially arranged along the first rotation center 20, and the lengths of the fixed block 221-1 and the movable block 221-3 are both greater than or equal to the width of the material. In this way, the pulling force provided by the clamping module 22 along the width direction of the material can be uniform, which can avoid the appearance of free ends in the shape of cuts or serrated edges when the cutting mechanism 3 cuts the material.

[0064] Specifically, the ejection mechanism 5 includes an ejection group 51 that is telescopic relative to the clamping mechanism 2; the ejection group 51 includes an ejection driving member 51-2 and an ejection block 51-3 provided at the output end of the ejection driving member 51-2, and the ejection driving member 51-2 drives the ejection block 51-3 to telescopically move toward the clamping station 221-4 to eject the material into the clamping station 221-4. More specifically, the thickness of the ejection block 51-3 is less than or equal to the width of the clamping station 221-4.

[0065] like Figure 6 As shown, more specifically, the material pushing group 51 also includes a material pressing piece 51-4, and the material pressing piece 51-4 is arranged adjacent to the material pushing block 51-3; the material pressing piece 51-4 is used to press the material, and after the cutting mechanism 3 cuts the material, press the formed free end of the material, and allow the material pushing block 51-3 to insert the formed free end of the material into the clamping station 221-4 to complete the first folding step of the film-coated product, and the setting of the material pressing piece 51-4 prevents the material from detaching from the clamping mechanism 2, avoids the failure of the film coating, and affects the subsequent folding steps;

[0066] like Fig. 9 As shown, more specifically, the clamping group 221 is divided into two groups, and the two moving blocks 221 - 3 are arranged adjacent to each other; the pushing group 51 is divided into two groups, and is arranged opposite to the clamping station 221 - 4 .

[0067] like Figure 6 As shown, more specifically, the cutting mechanism 3 is arranged between the two groups of the top material groups 51.

[0068] like Figure 6 As shown, further, the cutting mechanism 3 includes a moving knife driving member 3-2, and a moving knife 3-3 arranged at the output end of the moving knife driving member 3-2; the length of the moving knife 3-3 is greater than or equal to the width of the material. After the material is coated on the surface of the piece to be coated 61 to form a coated piece 62, the moving knife 3-3 is driven by the moving knife driving member 3-2 to extend toward the clamping mechanism 2. The setting that the length of the moving knife 3-3 is greater than or equal to the width of the material means that only one driving member is used to cut the material, which can save the setting of the driving member; if the length of the moving knife 3-3 is less than the width of the material, it will lead to incomplete cutting, and it is necessary to add a driving member to drive the moving knife 3-3 to move back and forth along the width direction of the material to realize the cutting function.

[0069] like Fig. 9 As shown, there is a gap 221-5 between adjacent moving blocks 221-3. When the moving block 221-3 moves toward the clamping station 221-4 to clamp the material, the material is tensioned, so that the moving knife 3-3 extends to cut the material.

[0070] like Fig.11 As shown, specifically, the cutting mechanism 3 also includes a base plate 31, a guide shaft 32, a screw rod 35 and a cutting fixed plate 33; the base plate 31 is provided with the movable knife driving component 3-2 at one end, and the guide shaft 32 is provided at the other end; the guide shaft 32 is connected to the cutting fixed plate 33 at one end away from the base plate 31, the screw rod 35 passes through the base plate 31 and the cutting fixed plate 33, the lifting mechanism 5 and the movable knife 3-3 are arranged on the cutting fixed plate 33; the movable knife driving component 3-2 drives the screw rod 35 to rotate, so as to drive the lifting mechanism 5 and the movable knife 3-3 to move toward the direction of the clamping mechanism 2.

[0071] like Figure 3As shown, further, the second folding and turning mechanism 4 also includes a telescopic driving module 43 for driving the object clamping module 41 to telescopically move relative to the clamping mechanism 2, the telescopic driving module 43 includes a telescopic driving group 430, and the object clamping module 41 is respectively arranged at both ends of the telescopic driving group 430; the telescopic driving group 430 includes a slide rail 43-1, and slide blocks 43-3 are respectively arranged at both ends of the slide rail 43-1; the object clamping module 41 is arranged on the slide block 43-3;

[0072] The two sides of the slide rail 43 - 1 in the length direction are provided with clamping module driving parts 43 - 2 for separately driving the sliders 43 - 3 at the two ends of the slide rail 43 - 1 .

[0073] Specifically, the telescopic drive module 43 includes a first telescopic drive group 431 and a second telescopic drive group 432 arranged perpendicularly to the first telescopic drive group 431, the first telescopic drive group 431 is provided with a first slide rail 431-1, the second telescopic drive group 432 is provided with a second slide rail 432-1, the first slide rail 431-1 is fixed on the second slide rail 432-1, and the first slide rail 431-1 and the second slide rail 432-1 are arranged back to back.

[0074] More specifically, the telescopic driving modules 43 are divided into two groups, and the first telescopic driving group 431 and the second telescopic driving group 432 in each group are arranged parallel to each other.

[0075] like Figure 4 As shown, specifically, the object clamping module 41 includes a connecting member 411 arranged on the slide rail 43-1, the connecting member is provided with a clamping driving member 41-2, and the clamping driving member 41-2 is provided with an upper gripping clamp 412 and a lower gripping clamp 413; the upper gripping clamp 412 and the lower gripping clamp 413 move relative to each other under the drive of the clamping driving member 41-2 to clamp the wrapped member 62.

[0076] In this embodiment, the specific structure of the bare component clamping module 21 may be the same as that of the object clamping module 41 .

[0077] More specifically, the clamping drive member 41-2 includes a first clamping drive member 41-21 arranged on the front side of the connecting member 411, and a second clamping drive member 41-22 arranged on the rear side of the connecting member 411, the upper gripping clamp 412 is arranged on the second clamping drive member 41-22, and the lower gripping clamp 413 is arranged on the first clamping drive member 41-21.

[0078] like Figure 1 , Fig.10As shown, further, the unwinding mechanism 1 includes an unwinding center shaft 11, a coiling roller 12, a floating adjustment roller 13, a material driving member 14, and a connecting column 121; the film roll 7 is placed on the unwinding center shaft 11, and the output end of the material driving member 14 is connected to the unwinding center shaft 11; a floating adjustment roller 13 is provided above the unwinding center shaft 11, and the floating adjustment roller 13 is slidably arranged on the connecting column 121 to adjust and buffer the tension of the material. After the film roll 7 passes through the floating adjustment roller 13 and passes through the coiling roller 12, it is supplied to the clamping mechanism 2.

[0079] Taking the processing of coated products as an example, the working principle of this device is as follows:

[0080] Coating steps: Initially, such as Figure 1-2 As shown, the bare piece clamping module 21 is at the loading station 80, the clamping module 22 is located at the initial clamping station 90, and the clamping module 22 clamps the first free end of the film roll 7; the bare piece clamping module 21 clamps the piece to be coated 61;

[0081] The clamping mechanism 2 rotates clockwise with the first rotation center 20 as the center, and after the bare component clamping module 21 passes through the first clamping station 81 (at this time, the clamping module 22 is located on the first clamping station 91), the bare component clamping module 21 rotates toward the second clamping station 82; since the position of the unwinding mechanism 1 remains unchanged, between the first clamping station 81 and the second clamping station 82, the bare component clamping module 21 lifts up the film roll until the bare component clamping module 21 rotates to the second clamping station 82, and the film roll is coated on the surface of the to-be-coated component 61 to form a coated component 62;

[0082] Cutting and first folding steps: immediately following the above steps, when the bare part clamping module 21 clamps the coated part 62 and rotates to the second clamping station 82, the movable knife driving member 3-2 drives the screw 35 to rotate, driving the movable knife 3-3 and the ejecting mechanism 5 to extend toward the first rotation center 20, and at the same time, the pressing member 51-4 presses the film roll onto the clamping mechanism 2; the movable knife 3-3 extends toward the gap position 221-5 to cut the film roll to form a second free end and a new first free end; the ejecting block 51-3 is on the ejecting driving member 5 The material clamping station 221-4 is extended toward the material clamping station 221-4 under the driving of the material clamping module 1-2, and the free end formed in the cutting step is inserted into the material clamping station 221-4 to complete the first folding step, and then the material clamping driving member 51-2 drives the material clamping block 51-3 to reset; while the material clamping block 51-3 is reset, the material clamping driving member 221-2 drives the moving block 221-3 to close the material clamping station 221-4 to clamp the free end formed in the cutting step. At this time, the material clamping module 22 adjacent to the bare part clamping module 21 clamps the first free end and the second free end respectively;

[0083] The second folding and flipping step: the object clamping module 41 is located on one side of the third clamping station 82 and is in an open state; the bare part clamping module 21 is opened, and the object clamping module 41 moves toward the second clamping station 82 under the drive of the telescopic drive group 430 to remove the covered part 62 from the bare part clamping module 21. After the object clamping module 41 takes the covered part 62, the telescopic drive group 430 drives the object clamping module 41 to reset; then, the object clamping module 41 rotates counterclockwise around the second rotation center 40 to the third clamping station 83, and the first free end and the second free end on the covered part 62 are against the folding module 42 to complete the second folding and flipping; then, the object clamping module 41 continues to rotate to the fourth clamping station 84 to obtain a coated product and unload the material.
