The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.

The embodiment discloses an attaching device for attaching a first product to a second product. In this embodiment, the first product is a mylar film, the second product is a back plate, and both are substantially rectangular structures. Of course, in other embodiments, the first product and the second product are not limited to the mylar film or the back plate in the present application, but may be other products, which are not particularly limited herein; the present embodiment is mainly described by attaching a mylar film to a back plate.

As shown in fig. 1 and 2, the attaching device includes a first pressing block 50, a base 20, a suction plate 30 provided on the base 20, and a clamping mechanism 40; the suction plate 30 is used for sucking the first product; the clamping mechanism 40 comprises two first clamping pieces 41 oppositely arranged along a first direction (namely X direction in the drawing) and two second clamping pieces 42 oppositely arranged along a second direction (namely Y direction in the drawing), wherein the first direction is perpendicular to the second direction; referring to fig. 3 to 5, the clamping mechanism 40 further includes a first elastic member 43 and a second elastic member 44, the first elastic member 43 being disposed between the first clamping member 41 and the base 20 and configured such that the two first clamping members 41 always have a movement tendency toward each other along the first direction; the second elastic member 44 is disposed between the second clamping member 42 and the base 20, and configured such that the two second clamping members 42 always have a movement tendency toward each other along the second direction; both the first product and the second product can be clamped between two first clamping members 41 and two second clamping members 42. The first press 50 is used for pressing the second product. In this embodiment, the first product is attached to the lower portion of the second product.

In the implementation, first, the first product is clamped on the clamping mechanism 40, and under the action of the first elastic piece 43 and the second elastic piece 44, four sides of the first product are kept tightly abutted against the two first clamping pieces 41 and the two second clamping pieces 42 all the time, so that the first clamping pieces 41 and the second clamping pieces 42 are used for centering; then, the first product is sucked through the suction plate 30, and the feeding position of the first product is determined; feeding a second product, wherein the second product is positioned above the first product, and can be clamped by the clamping mechanism 40 in the same way, and the second product is centered by the clamping mechanism 40; finally, under the premise that the clamping mechanism 40 holds the second product, the first pressing block 50 presses the second product from top to bottom, and the first product and the second product are fully contacted, that is, the two products which are centrally positioned can be attached through the pressing action of the first pressing block 50.

The attaching device provided by the embodiment realizes the centering positioning of the first product by simultaneously clamping the first product by the two first clamping pieces 41 and the two second clamping pieces 42 of the clamping mechanism 40, and also performs centering positioning on the second product, and the two centered positioned products realize accurate attachment under the pressing effect of the first pressing block 50, so that the tolerance influence is eliminated, and the attaching deviation is avoided to be larger; meanwhile, the attaching device can realize automatic attaching operation, and solves the problems of low manual attaching efficiency and high reject ratio.

Typically, the mylar film is smaller in size than the back plate, i.e., the first product is smaller in size than the second product, where the dimensions refer to both the length dimension and the width dimension of the rectangular structure. When the clamping mechanism 40 clamps a second product of a larger size, the clamping members are all expanded outwards to increase the clamping range, so that the first product is separated from the clamping of the clamping mechanism 40, and therefore, before the clamping mechanism 40 clamps the second product, the first product which is positioned centrally is firmly adsorbed by the suction plate 30, and the clamping members of the subsequent clamping mechanisms 40 are expanded anyway, so that the position of the first product is not affected. Of course, in some other cases, the mylar film may be sized the same as the back plate, i.e., the first product and the second product have the same physical dimensions. At this time, when the clamping mechanism 40 clamps the second product, the clamping of the first product can still be maintained; however, in order to enhance the reliability of the position of the first product, the first product is still selectively sucked by the suction plate 30. When the size of the first product is larger than that of the second product, even if the first product is absorbed by the suction plate 30, the clamping range of the clamping mechanism 40 is still large, so that the clamping mechanism 40 cannot clamp the second product with a small size, and the second product cannot be positioned effectively, and therefore, the case is not applicable to the attaching device; however, in the embodiment, the first product and the second product may be inverted, that is, the second product is attached to the lower portion of the first product, so that the attaching device of the embodiment may still be applicable, and the specific operation process is similar, which is not repeated here.

Further, referring to fig. 3 to 7, the first clamping member 41 and the second clamping member 42 are identical in structure, and each includes a first bracket 411 and a second bracket 412; the first bracket 411 includes a clamping portion 4111 and a first connecting portion 4112 sequentially arranged from top to bottom, the first connecting portion 4112 is in rotation fit with the base 20, and the clamping portion 4111 is used for clamping a first product or a second product; the second bracket 412 includes a second connecting portion 4121 and a third connecting portion 4122 sequentially disposed from top to bottom, the second connecting portion 4121 is in a rotating fit with the clamping portion 4111 of the first bracket 411, and the third connecting portion 4122 is movably connected with the base 20. Further, the first elastic member 43 is disposed between the second bracket 412 of the first clamping member 41 and the base 20, and the second elastic member 44 is disposed between the second bracket 412 of the second clamping member 42 and the base 20. Namely, the first clamping member 41 and the second clamping member 42 are both provided with a connecting rod structure formed by two brackets, and through the movable fit between the second bracket 412 and the base 20 and the rotation fit between the second bracket 412 and the first bracket 411, the second bracket 412 can rotate with the first bracket 411, so that the clamping portions 4111 of the two opposite clamping members are mutually close to or far away from each other, and further the clamping actions of different products are completed. Alternatively, the above-mentioned rotation fit can be achieved by providing a rotation shaft.

Still further, the clamping mechanism 40 further includes a first pin 45 and a second pin 46, where the first pin 45 and the second pin 46 are both disposed on the base 20, and have a moving space along a vertical direction on the base 20; the third connecting portions 4122 of the second brackets 412 of the two first clamping members 41 are rotationally fitted on the same first pin body 45; the first elastic member 43 is connected between the first pin 45 and the base 20 in the vertical direction; the third connecting portions 4122 of the second brackets 412 of the two second clamping members 42 are rotationally fitted to the same second pin body 46; the second elastic member 44 is connected between the second pin 46 and the base 20 in the vertical direction. In particular, when the first bracket 411 clamps an article, the first bracket 411 will passively rotate, and when the first bracket 411 and the second bracket 412 are linked, the third connecting portion 4122 of the second bracket 412 will rotate and move vertically relative to the base 20, but under the action of the stretching elastic force of the elastic member, the second bracket 412 and the first bracket 411 always have a movement trend of returning to the original position, so that the article can be tightly clamped; and for two opposite clamping pieces, the second bracket 412 is connected to the same pin body, so that the clamping actions of the two clamping pieces are symmetrically completed under the drive of the same pin body, and the clamping displacement is kept the same, thereby further ensuring the centering positioning when clamping the product.

For the two first clamping members 41, the rotation axes of the first connecting portion 4112, the second connecting portion 4121 and the third connecting portion 4122 are parallel and each extend along the second direction, and the corresponding first pin 45 also extends along the second direction. For the two second clamping members 42, the rotation axes of the first connecting portion 4112, the second connecting portion 4121 and the third connecting portion 4122 are parallel and each extend along the first direction, and the corresponding second pin 46 extends along the first direction. Further, the first pin body 45 and the second pin body 46 are disposed at intervals in the vertical direction; so that there is no interference between the different second brackets 412.

Alternatively, the first elastic member 43 and the second elastic member 44 are both tension springs. In particular, the number of the first elastic members 43 and the second elastic members 44 is not particularly limited, and may be one, or may be two, three, or more. Further, referring to fig. 4, a connecting rod 23 may be disposed at the bottom of the base 20, and a tension spring between a pin body at the lower side and the base 20 may be hooked at one end to the pin body and the other end to the connecting rod 23 of the base 20. In this embodiment, the first pin 45 is located below the second pin 46; correspondingly, one end of the tension spring serving as the first elastic member 43 is hooked on the first pin body 45, and the other end is hooked on the connecting rod 23.

Specifically, referring to fig. 3 and 4, the base 20 is provided with a first bar-shaped hole 21 and a second bar-shaped hole 22 extending in a vertical direction, and the first pin body 45 and the second pin body 46 are respectively inserted into the first bar-shaped hole 21 and the second bar-shaped hole 22. More specifically, two first bar-shaped holes 21 are oppositely arranged along the second direction, and two free ends of the first pin body 45 are respectively inserted into the two first bar-shaped holes 21; the two second bar-shaped holes 22 are oppositely arranged along the first direction, and two free ends of the second pin body 46 are respectively inserted into the two second bar-shaped holes 22. Optionally, the first pin body 45 and the second pin body 46 penetrate through corresponding bar-shaped holes, and are fixed through snap springs after penetrating through, so that the positions are relatively stable.

For example, referring to fig. 5 to 7, for the two first holders 41, two second brackets 412 are provided in the space between the two first brackets 411; the same applies to the two second clamping members 42. Further, referring to fig. 2 to 4, the base 20 is of a hollow square structure, the suction plate 30 is disposed on top of the base 20, four first brackets 411 are respectively disposed on four sides of the base 20, and the clamping portions 4111 are protruded from the suction plate 30; the second bracket 412 is accommodated inside the base 20. The arrangement can hide part of the parts in the base 20, fully utilize the space of the base 20 and improve the compactness of the whole attaching device.

In an embodiment, referring to fig. 1 and 2, the attaching device further includes a supporting mechanism 70, where the supporting mechanism 70 includes a linear driving member 71, a first supporting block 72 and a second supporting block 73 disposed opposite to each other along a first direction, and supporting planes of the first supporting block 72 and the second supporting block 73 are located at a same level, and a second product can be supported on the first supporting block 72 and the second supporting block 73 at the same time, and the linear driving member 71 is used to drive the first supporting block 72 and the second supporting block 73 to approach or separate from each other along the first direction. Because the second product is put in, even if clamped by the clamping mechanism 40, the second product cannot be kept horizontal and is not beneficial to accurate alignment, the supporting mechanism 70 is arranged, so that the second product is supported on the first supporting block 72 and the second supporting block 73 which are oppositely arranged at the same time, and the supporting planes of the first supporting block 72 and the second supporting block 73 are positioned at the same horizontal height, so that the level of the second product positioned on the second supporting block can be ensured, and the centering positioning of the second product is more accurate; when the first pressing block 50 is attached, the first supporting block 72 and the second supporting block 73 are driven by the linear driving piece 71 to be far away from each other, so that the attachment of the second product and the first product is not affected.

Alternatively, two first support blocks 72 and two second support blocks 73 may be provided, and two first support blocks 72 and two second support blocks 73 are provided on both sides of the first clamping member 41 on the corresponding sides, respectively, to ensure a horizontal supporting effect. Further, the linear driving member 71 may be a bidirectional cylinder, i.e. two output ends are disposed on the same cylinder body, the first support block 72 and the second support block 73 are respectively connected to the two output ends, and the first support block 72 and the second support block 73 can be synchronously driven to approach or separate from each other when the cylinder is started, so as to ensure the motion synchronism. Further, the cylinder output end is connected with the supporting block through a connecting bracket 74. Specifically, the upper surfaces of the first support block 72 and the second support block 73 are each provided with a step 721, and the second product is supported on the step 721 face of the step 721; the step 721 also can limit the second product in the first direction, so that the second product is prevented from being excessively shifted when being put in, and the positioning-related function of the first clamping piece 41 is assisted.

Further alternatively, the first product and the second product are each rectangular in configuration. In particular, the length of the clamping portion 4111 of the first bracket 411 of the first clamping member 41 is greater than the length of the clamping portion 4111 of the first bracket 411 of the second clamping member 42, so that the first clamping member 41 is used for clamping the long side of the rectangular product structure, and the second clamping member 42 is used for clamping the short side of the rectangular product structure. In some other embodiments, the length of the clamping portion 4111 of the first bracket 411 of the first clamping member 41 is smaller than the length of the clamping portion 4111 of the first bracket 411 of the second clamping member 42, so that the first clamping member 41 is used to clamp the short side of the rectangular product structure, and the second clamping member 42 is used to clamp the long side of the rectangular product structure. That is, the lengths of the clamping portions 4111 of the two clamping members are different, and the long side of the product is clamped by the long clamping portion, and the short side of the product is clamped by the short clamping portion, so that the clamping stability of the related product is further improved. Further, a guiding inclined surface 4113 is disposed on the clamping portion 4111 of the first bracket 411; the guiding inclined surface 4113 can guide the product to be put in, so that the product can be put in conveniently. Obviously, the guiding ramp 4113 is provided on the side of one clamping member facing the other clamping member of the same type.

Illustratively, the attaching device further includes a second pressing block 60, where the second pressing block 60 is used for pressing the first product. As the Mylar film of the first product, because of the large area, in order to avoid insufficient spreading when the suction plate 30 is adsorbed, the Mylar film is fully attached to the suction plate 30, thereby affecting the attachment of the second product, the first product can be pressed by the second pressing block 60 before the second product is fed, so that the first product is completely spread and fully adsorbed by the suction plate 30, and the second pressing block 60 is evacuated after the pressing is completed. In specific implementation, referring to fig. 2 and 8, one of the second pressing block 60 and the suction plate 30 is provided with a positioning column 31, and the other is provided with a positioning hole 61, and the positioning column 31 can be inserted into the positioning hole 61. Through the setting of the positioning mechanism, the second pressing block 60 can be accurately placed when being pressed, and the spreading effect is ensured. Alternatively, the positioning columns 31 and the positioning holes 61 are arranged in a plurality and one-to-one correspondence; in the present embodiment, the positioning posts 31 are provided on the suction plate 30, and two are provided. Further, the suction plate 30 has a rectangular structure, and two positioning posts 31 are respectively disposed at a set of diagonal positions of the suction plate 30. Optionally, handles are provided on both the first 50 and second 60 press blocks.

Further, referring to fig. 1, the attaching device further includes a case 10, and the base 20 is located in the case 10; the top of the case 10 is opened with an opening, and the suction plate 30, the first clamping member 41 and the second clamping member 42 are all exposed from the opening. In specific implementation, the base 20 and most of the clamping mechanism 40 can be hidden through the arrangement of the box body 10, and only the part which needs to be operated is exposed, so that the operation convenience of the whole attaching device is improved, and the influence of the external environment on the service life of mechanical components is avoided. Other associated components may also be disposed within the cartridge 10 accordingly.

Specifically, referring to fig. 1 and 2, the outer edge of the suction plate 30 is provided with a relief groove 32, and the relief groove 32 is used for accommodating the first clamping member 41 and the second clamping member 42. Since the first bracket 411 is spatially displaced during the process of clamping different products by the clamping mechanism 40, a movable space is required for the movement of the first bracket 411; by providing the relief groove 32 at the outer edge of the suction plate 30, a certain movable space is created between the suction plate 30 and the case 10. Of course, in the implementation, the corresponding movable space can be provided by controlling the shape, structure and size of the opening. In this embodiment, on the premise that the suction plate 30 satisfies the placement of the first product, the relief groove 32 is formed on the suction plate 30, so that the compactness of the whole attaching device can be further improved. Further, the outer edge of the base 20 may also be correspondingly provided with a groove body communicated with the abdication groove 32 of the suction plate 30, so as to satisfy the placement of the whole first bracket 411.

In the present embodiment, the linear driving member 71 of the supporting mechanism 70 is also provided in the case 10, but the first supporting block 72 and the second supporting block 73 are exposed from the case 10; in practice, it is necessary to slot or expand the open structure in the case 10 to provide space for the first support block 72 to move. Further, a guiding mechanism 75 is arranged between the supporting block and the box body 10, the guiding mechanism 75 comprises a sliding rail extending along the first direction and a sliding block arranged on the sliding rail in a sliding manner, the sliding rail is arranged on the box body 10, and the sliding block is arranged on the supporting block. The provision of the guide mechanism 75 can provide a guide for movement of the support block in the first direction, ensuring accuracy of movement of the support block in the first direction. Optionally, the case 10 has a square structure; the slide rail is provided inside the top plate of the box body 10.
