[0022] In the description of the present invention, if there is a description of first and second, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0023] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0024] The following is the attached Figure 1 To Attachment Figure 6 , describing the diaphragm adsorption and mounting mechanism 94 of the first aspect of the embodiment of the present invention.

[0025] Reference Figures 1 to 5 The diaphragm adsorption and mounting mechanism 94 of this embodiment includes a hanging frame 10, a pressing head assembly 20 and a stretching elastic member 40; wherein, the pressing head assembly 20 can be slidably connected to the hanging frame 10 in the vertical direction, and a suction plate 21 is provided at the bottom of the pressing head assembly 20, and a suction hole 211 for adsorbing the diaphragm is provided on the lower surface of the suction plate 21, so that the pressing head assembly 20 can adsorb the diaphragm through the suction plate 21 at its bottom, and then the diaphragm can be mounted on the product; the stretching elastic member 40 is used to balance and offset the gravity of the pressing head assembly 20, wherein the upper end of the stretching elastic member 40 is connected to the hanging frame 10 and the lower end is connected to the pressing head assembly 20, so that the pressing head assembly 20 is suspended on the hanging frame 10.

[0026] It should be understood that the diaphragm adsorption and mounting mechanism 94 of the present embodiment can enable the ram assembly 20 to move upward relative to the hanging frame 10 when the film is applied, thereby ensuring that the diaphragm is in full contact and fit with the product while avoiding excessive squeezing of the product due to excessive descending stroke (generally, the descending stroke of the ram assembly 20 during film application is slightly greater than the distance between the ram assembly 20 and the film application surface of the product before film application) by arranging the ram assembly 20 to be slidably connected to the hanging frame 10 in the vertical direction, and assisting in the suspension of the ram assembly 20 by stretching the elastic member 40. In addition, since the pulling force of the stretching elastic member 40 on the ram assembly 20 can also offset the gravity of the ram assembly 20, when the product film application area is large, and thus the area and weight of the ram assembly 20 are large, it is not easy to damage the product, which is beneficial to improving the yield rate of large-area diaphragm mounting.

[0027] It is understood that in one embodiment, referring to Figure 2 and Figure 5 The stretching elastic member 40 is a stretching spring, and in order to facilitate the connection of the two ends of the stretching spring to the suspension frame 10 and the pressure head assembly 20, the suspension frame 10 is provided with a first pull ring 111 for cooperating with the top hook of the stretching spring, and the pressure head assembly 20 is provided with a second pull ring 231 for cooperating with the bottom hook of the stretching spring; it should be understood that in some other embodiments, the stretching elastic member 40 can also choose to use other stretching elastic members 40 such as elastic draw ropes.

[0028] In some of these embodiments, reference Figure 2 and Figure 5, the film adsorption and mounting mechanism 94 also includes a compression elastic member 50 and a pressure sensor 60, wherein the pressure sensor 60 is arranged on the pressure head assembly 20, and the compression elastic member 50 is connected to the suspension frame 10 at one end and the pressure sensor 60 at the other end, so that the pressure applied by the compression elastic member 50 can be detected by the pressure sensor 60, and then the pressure applied by the pressure head assembly 20 to the product when the film is applied can be obtained. It should be understood that the external force applied to the pressure head assembly 20 during film application mainly includes its own gravity G, the downward pressure F1 applied by the compression elastic member 50, the tension F2 provided by the two tension springs and the reaction force F3 applied by the product during film application, wherein G, and F1 are directed downward, while F2 and F3 are directed upward, therefore according to the principle of mechanical balance, G+F1=F2+F3, so the pressure F3 applied by the pressure head assembly 20 to the product=G+F1-F2, and since the pressure head assembly during film application The descending stroke of 20 is generally slightly larger than the distance between the pressure head assembly 20 and the film-sticking surface of the product before film sticking. Therefore, the distance that the pressure head assembly 20 slides upward relative to the suspension frame 10 when film sticking is also much smaller than the deformation of the tension spring, that is, F2 remains basically unchanged before and after film sticking, so F2 can be regarded as always approximately equal to G, and therefore F3≈F1, that is, the pressure applied to the product by the pressure head assembly 20 can be detected and obtained in real time through the pressure sensor 60, so as to further reduce the risk of the diaphragm adsorption and mounting mechanism 94 crushing the product when film sticking.

[0029] It should be understood that referring to Figure 5 In one embodiment, the compression elastic member 50 is a compression spring; and the stiffness coefficient of the compression spring is set to be greater than the accuracy coefficient of the tension spring to further reduce the difference between the pressure value detected by the pressure sensor 60 and the pressure value actually applied by the pressure head assembly 20 to the product.

[0030] In some of these embodiments, reference Figure 5 The pressure head assembly 20 also includes a sliding frame 23 and a connecting rod 27. The pressure head assembly 20 is slidably connected to the suspension frame 10 through the sliding frame 23, and the connecting rod 27 is arranged on the sliding frame 23; the suction plate 21 is provided with a spherical bearing seat 22, and is sleeved on the lower end of the connecting rod 27 through the spherical bearing seat 22. It should be understood that when filming the product, it is necessary to make the film located on the lower surface of the suction plate 21 and the surface of the product to be filmed to be fully fitted, and through the cooperation of the spherical bearing seat 22 and the connecting rod 27, the suction plate 21 can be multi-directionally rotated relative to the lower end of the connecting rod 27 to adjust the angle and posture, so that the suction plate 21 can be rotated when adjusting the machine so that the suction plate 21 can be highly parallel to the surface of the product to be filmed, thereby ensuring that the film can fully fit the surface of the product to be filmed when filming.

[0031] It can be understood that, based on some of the above embodiments, the sliding frame 23 is provided with an angle adjustment structure, which is connected to the suction plate 21 and is used to adjust the angle posture of the suction plate 21, so as to further improve the convenience of adjusting the angle posture of the suction plate 21. Figure 1 The sliding frame 23 includes an adjustment plate 24 located above the suction plate 21, and the adjustment plate 24 is provided with a plurality of vertically extending threaded holes, and the plurality of threaded holes are arranged at intervals; the angle adjustment structure includes a plurality of adjusting bolts 28, and the plurality of adjusting bolts 28 are correspondingly arranged in the plurality of threaded holes, and the lower ends thereof are in contact with the suction plate 21, so that the angle posture of the suction plate 21 can be adjusted by rotating and adjusting the height of each adjusting bolt 28 protruding from the lower surface of the adjustment plate 24, and because the suction plate 21 is in contact with the adjusting bolt 28, after the angle posture of the suction plate 21 is adjusted, the adjusting bolt 28 can also play a role in limiting the rotation of the suction plate 21 under the action of external force, so that the suction plate 21 can be maintained at the adjusted angle. It should be understood that in one embodiment, each edge of the adjustment plate 24 is correspondingly provided with a plurality of adjusting bolts 28, and the connecting rod 27 is vertically arranged in the inner side of the area enclosed by the connecting line between the plurality of adjusting bolts 28.

[0032] It is understandable that in order to achieve the sliding connection between the sliding frame 23 and the suspension frame 10, in some embodiments, reference is made to Figure 2 and Figure 5 The suspension frame 10 includes a top plate 11 and two side plates 12, the two side plates 12 are respectively connected to the two ends of the bottom of the top plate 11, and the sliding frame 23 includes vertical plates 25 respectively opposite to the two side plates 12, and the vertical plates 25 are slidably connected to the side plates 12 along the vertical direction. Figure 2 A first slide rail 251 extending in the vertical direction is provided on the side of the vertical plate 25 facing the side plate 12, and a first slider 121 slidably matched with the first slide rail 251 is fixedly connected to the side plate 12, so that relative sliding can be achieved between the vertical plate 25 and the side plate 12 by virtue of the cooperation between the first slide rail 251 and the first slider 121.

[0033] It can be understood that in some of the embodiments, the spherical bearing seat 22 is connected to the center of the upper surface of the suction plate 21 so that the center of gravity of the pressing head assembly 20 can be located on the vertical axis where the connecting rod 27 is located, and two tensile elastic members 40 are provided and are symmetrically arranged about the connecting rod 27, so that the same magnitude of suspension tension can be provided to the pressing head assembly 20 through the two tensile elastic members 40 to avoid obvious angular deviation of the pressing head assembly 20 under the tension of the tensile elastic member 40.

[0034] For example, refer to Figures 1 to 6In one embodiment, the sliding frame 23 also includes a connecting plate 26, wherein a connecting rod 27 is vertically penetrated and fixed at the center of the connecting plate 26, the connecting plate 26 is connected to the upper side of the adjustment plate 24, and the adjustment plate 24 is connected to the lower ends of the two vertical plates 25, and a clearance opening is provided in the middle of the adjustment plate 24 to allow the connecting rod 27 to pass through, and the spherical bearing seat 22 connected to the center of the upper surface of the suction plate 21 is at least partially located in the clearance opening to reduce the height size of the pressure head assembly 20; two second pull rings 231 are provided, and are symmetrically arranged on the connecting plate 26 with respect to the connecting rod 27, and two first pull rings 111 are also provided, and are arranged on the top plate 11 of the suspension frame 10, and are located at a position opposite to the top plate 11 and the two second pull rings 231, so that the two tension springs connected to the first pull ring 111 and the second pull ring 231 at both ends can be symmetrical with each other about the connecting rod 27. In addition, a second slider 261 is provided on the upper surface of the connecting plate 26 adjacent to the connecting rod 27. The suspension frame 10 includes a vertical plate 13 whose upper end is connected to the top plate 11 and whose lower end extends vertically downward. The vertical plate 13 is opposite to the second slider 261 and is provided with a second slide rail that cooperates with the second slider 261 to guide the sliding of the pressure head assembly 20 at a position adjacent to the middle of the connecting plate 26, thereby further improving the sliding stability of the pressure head assembly 20 on the suspension frame 10. At the same time, to facilitate the installation of the compression spring and the pressure sensor 60, a fixing seat 262 is provided on the side of the second slider 261 facing the connecting rod 27, and a supporting portion 263 located on the upper side of the connecting rod 27 is formed on the fixing seat 262. The pressure sensor 60 is installed on the supporting portion 263, and the lower end of the compression spring abuts against the pressure sensor 60. The compression spring is coaxially arranged with the connecting rod 27, so that the pressure applied by the compression spring to the pressure head assembly 20 can be coaxial with the connecting rod 27, thereby avoiding the problem of obvious angular deviation of the pressure head assembly 20 under the pressure applied by the compression spring.

[0035] It should be understood that in order to enable the pressure applied by the compression spring to the pressure head assembly 20 to be coaxial with the connecting rod 27 , in some other embodiments, the pressure sensor 60 may also be directly fixedly mounted on the top of the connecting rod 27 .

[0036] It is understood that in some of these embodiments, reference Figure 1The diaphragm adsorption and mounting mechanism 94 also includes a carrier plate 70 and a rotary driver 80, and the diaphragm adsorption and mounting mechanism 94 can be integrally mounted and connected to a mobile driving component (such as the mounting drive module to be mentioned in the second embodiment) through the carrier plate 70, so that the diaphragm adsorption and mounting mechanism 94 can be driven by the mobile driving component to move, so as to achieve operations such as taking and mounting the diaphragm. The rotary driver 80 is disposed on the carrier plate 70, and is connected to the suspension frame 10, and is used to drive the suspension frame 10 to rotate around the vertical axis, so that the pressure head assembly 20 and the diaphragm adsorbed on the pressure head assembly 20 can be driven to rotate together through the suspension frame 10, thereby achieving the adjustment of the diaphragm angle.

[0037] The following describes a mounting device according to an embodiment of the second aspect of the present invention, and the mounting device according to this embodiment includes the film adsorption mounting mechanism 94 according to the embodiment of the first aspect. It should be understood that by adopting the film adsorption mounting mechanism 94 according to the embodiment of the first aspect, the mounting device can be made not to easily crush the product when mounting a large-area film, which is conducive to improving the yield rate of mounting large-area films.

[0038] It is understood that in some of these embodiments, reference Figure 7 The mounting device also includes a mounting drive module, and a diaphragm adsorption mounting mechanism 94 is connected to the end driving part of the mounting drive module.
