[0031] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.
[0032] It should also be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there may be an intermediate element present at the same time.

[0033] In addition, the descriptions involving "first", "second", etc. in the present utility model are only for descriptive purposes, and cannot be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.
[0034] The present utility model provides a multi-functional laminating machine for a curved screen, which is used to laminate a first component on a second component, where the first component can be a handwriting paper, an OCA film, an inner screen, and the second component is an outer screen, such as Figures 1 to 3As shown in the figure, the curved screen multi-functional laminating machine includes a machine table 100, a first component feeding mechanism 200, a first manipulator 300, a laminating platform 400, a second component positioning platform 500, a second manipulator 600, and a vacuum mechanism 700a arranged on the machine table 100. The machine table 100 can adopt an existing frame structure and will not be limited here. The first component feeding mechanism 200 is used to store the first component to facilitate the continuous grasping of the first component by the first manipulator 300. As for the storage method, it can be a cavity adapted to the first component, or the first component can be continuously conveyed through a conveyor line. The first manipulator 300 is used to grasp the first component located on the first component feeding mechanism 200 onto the laminating platform 400. In addition, the preferred way for the first manipulator 300 to grasp the first component is vacuum adsorption to avoid damaging the first component during the grasping process. The second component positioning platform 500 is used to position the second component. The positioning method can be to move the second component on the second component positioning platform 500 to a preset position to facilitate the grasping by the second manipulator 600. The second manipulator 600 is used to grasp the second component located on the second component positioning platform 500 onto the laminating platform 400 and attach it to the first component, and to grasp the semi-finished product after attachment into the vacuum mechanism 700a. The preferred way for the second manipulator 600 to grasp the second component is vacuum adsorption to avoid damaging the second component during the grasping process. Of course, the clamping method can also be used. The vacuum mechanism 700a is used to evacuate and pressurize the semi-finished second component. By evacuating the air, the air between the second component and the first component can be discharged, which can further enhance the bonding performance between the first component and the second component.The fitting platform 400 includes a base 410, a fixed supporting block 420, an annular supporting plate 430, and a first driving member. The base 410 is disposed on the machine table 100, the fixed supporting block 420 is disposed on the base 410, and a plurality of first vacuum suction holes 421 are provided on the top surface of the fixed supporting block 420. The annular supporting plate 430 is sleeved on the fixed supporting block 420, and a plurality of second vacuum suction holes 431 are provided on the top surface of the annular supporting plate 430 around its central through hole. The first vacuum suction holes 421 and the second vacuum suction holes 431 form a first placement position for placing the first component. The size of the first placement position is adapted to the size of the first component. The first driving member is disposed on the base 410 and is used to drive the annular supporting plate 430 to move closer to or away from the base 410 in the up and down direction. The first driving member is preferably a linear cylinder to facilitate driving the annular supporting plate 430 to reciprocate up and down. The specific operation mode is that in the normal state, the annular supporting plate 430 and the fixed supporting block 420 are at the same horizontal position to facilitate placing the first component. After the second manipulator 600 contacts the second component with the first component, the first driving member drives the annular supporting plate 430 to move downward, and the first component is independently supported by the fixed supporting block 420. And the second manipulator 600 drives the second component to continue moving downward to be completely attached to the first component. Since the downward movement of the annular supporting plate 430 provides an avoidance space for the bent portion at the edge of the second component, the first component can be completely attached to the second component. In this embodiment, the first manipulator 300 places the first component on the fitting platform 400, and the second manipulator 600 places the second component on the first component located on the fitting platform 400. And the fitting platform 400 provides an avoidance space during the attachment process of the second component and the first component, so as to facilitate the complete attachment of the bent side surface of the second component to the first component. Finally, the air between the first component and the second component is removed by the vacuum pumping mechanism 700a, so that the first component and the second component are attached more closely. The production of the curved screen is completed in an automated manner, improving the production speed. Moreover, the curved screen multi-functional fitting machine of this embodiment can complete the fitting of the handwriting paper, the OCA film, and the inner screen on the outer screen, improving the versatility of the equipment.
[0035] In a preferred embodiment, as Figure 4As shown, preferably, the first component feeding mechanism 200 includes a first mounting frame 210, a lifting plate 220, and a second driving member 230. The first mounting frame 210 is disposed on the machine table 100, and the first mounting frame 210 has a storage cavity 211 for storing the first component. The top of the storage cavity 211 is open. Preferably, the size of the storage cavity 211 can be adjusted to facilitate placing first components of different sizes, that is, to facilitate the production of display screens of different sizes and improve versatility. The way to adjust the size of the storage cavity 211 can be to set baffles with variable spacing, and the size of the storage cavity 211 is controlled by adjusting the spacing between the baffles. The lifting plate 220 is located in the storage cavity 211. Preferably, the size of the lifting plate 220 is adapted to the first component to facilitate placing the first component on the lifting plate 220. The second driving member 230 is disposed on the first mounting frame 210 and is used to drive the lifting plate 220 to move toward the opening of the storage cavity 211. Preferably, the second driving member 230 is in the form of a motor + lead screw to facilitate controlling the position of the lifting plate 220, that is, after the first manipulator 300 grabs the first component in the storage cavity 211 for a certain number of times, the second driving member 230 drives the lifting plate 220 to move up by the corresponding distance to facilitate the second manipulator 600 to stably grab the first component. In this embodiment, stacking and storing the first components in the storage cavity 211 is beneficial to increasing the storage quantity of the first components, reducing the number of times of replenishing the first components, and using the second driving member 230 to drive the lifting plate 220 to move can make it more stable for the second manipulator 600 to grab the first component, avoiding the situation that the second manipulator 600 cannot grab the first component in the storage cavity 211.
[0036] In a preferred embodiment, as Figure 3 shown, preferably, the fitting platform 400 further includes a third driving member 440 disposed on the machine table 100. The output end of the third driving member 440 is connected to the base 410 to drive the base 410 to move from the unloading position of the first manipulator 300 to the unloading position of the second manipulator 600. Among them, the third driving member 440 is preferably in the form of a motor + lead screw to facilitate driving the base 410 to move between the first manipulator 300 and the second manipulator 600. Moreover, since the second manipulator 600 needs to place the semi-finished second component in the vacuum pumping mechanism 700a, driving the base 410 to move by the third driving member 440 can effectively reduce the travel of the second manipulator 600 and improve work efficiency.
[0037] In a preferred embodiment, as Figure 5As shown, the preferred curved screen multi-functional laminating machine further includes a film taking mechanism 800 and a recycling box 110 disposed on the machine table 100. The film taking mechanism 800 is used to remove the protective film on the first component located at the first placement position and place it in the recycling box 110. Among them, in order to protect the first component, a protective film is generally covered on the first component. Preferably, the film taking mechanism 800 includes a third mounting frame 810, an eighth driving member 820, and a chuck 830. The third mounting frame 810 is disposed on the machine table 100, the eighth driving member 820 is disposed on the third mounting frame 810, and the chuck 830 is connected to the output end of the eighth driving member 820. In this embodiment, when the laminating platform 400 is fixed, the chuck 830 can be driven by the eighth driving member 820 to move to the first placement position (i.e., the base 410), then the protective film on the first component is clamped by the chuck 830, and finally the chuck 830 is driven by the eighth driving member 820 to reset to remove the protective film from the first component. In the case where the laminating platform 400 is movable, that is, when the third driving member 440 is provided, the eighth driving member 820 can drive the chuck 830 to move to a preset point on the movement track of the first placement position. When the first placement position moves to this point, it stops moving, and after the chuck 830 clamps the protective film, the first placement position continues to move, so that the protective film can be removed by dislocation. In addition, since the first component is adsorbed by the first vacuum adsorption holes 421 and the second vacuum adsorption holes 431 at this time, the first component will not move under external force. The size of the recycling box 110 is set according to the actual situation and is not limited here. After the chuck 830 removes the protective film, the protective film can be placed in the recycling box 110.
[0038] In a preferred embodiment, as Figure 6 and Figure 7As shown, preferably, the second component positioning platform 500 includes a fourth driving member 510 and an automatic calibration seat 520. The fourth driving member 510 is arranged on the machine table 100 and is used to drive the automatic calibration seat 520 to move below the loading point of the second manipulator 600. The automatic calibration seat 520 includes a bearing plate 521 connected to the output end of the fourth driving member 510 and a horizontal clamping assembly 522 arranged on the bearing plate 521. The bearing plate 521 has a second placement position 523 for placing the second component. The horizontal clamping assembly 522 is used to position the second component located on the second placement position 523. Among them, preferably, the fourth driving member 510 is a linear module, so as to drive the automatic calibration seat 520 to move between two end points. One end point is convenient for placing the second component on the second placement position 523. The specific placement method can be manual placement or using a manipulator, and the other end point is convenient for the second manipulator 600 to grab the second component. The horizontal clamping assembly 522 can be in the form of a cylinder + chuck 830. A plurality of push rods are arranged around the circumference of the second placement position 523, and a plurality of cylinders are used to drive the plurality of push rods to move horizontally towards the second placement position 523 respectively, so as to accurately position the second component on the second placement position 523. Two fixed blocks can also be arranged on the bearing plate 521 on the circumference of the second placement position 523. At this time, there are two push rods. One fixed block is arranged opposite to one push rod, and the other fixed block is arranged opposite to the other push rod. And the two push rods and the two fixed blocks are all arranged around the circumference of the second placement position 523. Using two cylinders to drive the two chucks 830 to move towards the corresponding fixed blocks can achieve the positioning of the second component on the second placement position 523. Compared with the previous method, this method is beneficial to reducing the number of cylinders and lowering the cost. In this embodiment, using the horizontal clamping assembly 522 to position the second component located on the second placement position 523 facilitates the second manipulator 600 to grab the second component.
[0039] In a preferred embodiment, as Figure 8As shown, the preferred curved screen multi-functional laminating machine further includes an image acquisition mechanism 900. The image acquisition mechanism 900 includes a bracket 910 disposed on the machine table 100, and a first CCD component 920 and a second CCD component 930 disposed on the bracket 910. The first CCD component 920 is used to acquire the position data of the second component located on the second component positioning platform 500, and the second CCD component 930 is used to acquire the position data of the first component located on the first placement position. Among them, preferably, the first CCD component 920 includes a first camera and a first fill light. The first camera is disposed on the bracket 910 and directly above the movement trajectory of the second placement position 523, so as to facilitate acquiring the position and placement angle data of the second component. The first fill light is disposed on the machine table 100 and on the side of the movement trajectory of the first placement position, so as to facilitate outlining the outer contour of the second component with light. The second CCD component 930 includes a second camera and a second fill light. The second camera is disposed on the bracket 910 and directly above the movement trajectory of the first placement position, so as to facilitate acquiring the position and placement angle data of the first component. The second fill light is disposed on the laminating platform 400 (i.e., the base 410) and below the first placement position, so as to facilitate outlining the outer contour of the first component with light. In this embodiment, by using the first CCD component 920 to acquire the position and placement angle data of the outer screen and using the second CCD component 930 to acquire the position and placement angle data of the outer screen, it is convenient for the second manipulator 600 to adjust the position and placement angle of the second component, so as to laminate the second component on the first component.

Among them, the fitting platform 400, the second component positioning platform 500, and the vacuum mechanism 700a are arranged in parallel in sequence. The gantry 610 straddles both sides of the fitting platform 400 and the vacuum mechanism 700a, so as to grab the second component onto the first component of the fitting platform 400, and then place the semi-finished product after fitting in the vacuum mechanism 700a. The three-axis drive mechanism 620 is used to drive the gripping head 640 to move in the X, Y, and Z directions. The rotary drive member 630 is used to drive the gripping head 640 to rotate around the Z axis, so as to facilitate grabbing the second component and at the same time, the three-axis drive mechanism 620 and the rotary drive member 630 can be used to adjust the position and placement angle of the grabbed second component, so that the second component is accurately fitted with the first component. Specifically, after the first CCD component 920 obtains the position and placement angle data of the second component and the second CCD component 930 obtains the position and placement angle data of the first component, the three-axis drive mechanism 620 and the rotary drive member 630 can adjust the position of the second component according to the above data, and then fit the second component with the first component, thereby improving the fitting accuracy.

Among them, preferably, the turntable 740a is provided with two third placement positions 741a, so that when the semi-finished component on one of the third placement positions 741a is being evacuated, the semi-finished second component can be placed above the other third placement position 741a and the display screen that has been evacuated on this third placement position 741a can be removed. The sixth driving member 750a is preferably a motor, which is convenient for controlling the rotation angle of the turntable 740a. An optical switch can also be provided to control the stop position of the turntable 740a. The size of the vacuum hood 720a is adapted to the third placement position 741a, so that when the vacuum hood 720a covers the turntable 740a, it completely covers the third placement position 741a.

Then, the fifth driving member 730a drives the vacuum hood 720a to move downward and abut against the turntable 740a to form a sealed space. Finally, the air in the sealed space is extracted through the air extraction hole to form a vacuum state, so that the second component is more closely attached to the first component.

The lower vacuum box 750b has a fourth placement position for placing semi-finished parts. Among them, the air extraction holes of the upper vacuum box 730b are communicated with an external vacuum machine through air pipes, or a vacuum machine can also be arranged on the machine table 100. The ninth driving member 720b is preferably a linear cylinder to facilitate driving the upper vacuum box 730b to move. The tenth driving member 740b is preferably in the form of a motor + lead screw + slide rail. The lower vacuum box 750b is respectively connected to the slider on the slide rail and the nut on the lead screw. The motor is used to drive the lead screw to rotate, thereby driving the lower vacuum box 750b to move. In addition, the lower vacuum box 750b has a fourth placement position for placing semi-finished parts to facilitate the second manipulator to place the semi-finished parts in the lower vacuum box 750b. In this embodiment, first, the second manipulator places the semi-finished parts on the fourth placement position, then uses the tenth driving member 740b to drive the lower vacuum box 750b to move to directly below the upper vacuum box 730b, and then uses the ninth driving member 720b to drive the upper vacuum box 730b to move downward and dock with the lower vacuum box 750b, so that a sealed space is formed by the upper vacuum box 730b and the lower vacuum box 750b. Finally, the air in the sealed space is extracted through the air extraction holes to form a vacuum state to ensure that the second component and the first component in the semi-finished parts are closely attached together. In addition, the upper vacuum box 730b can also be provided with a pre-pressing component 760b by referring to the pre-pressing component 760a on the above-mentioned vacuum cover 720a, which will not be described in detail here.
