[0045] In order to make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0046] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0047] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0048] Existing electronic display devices, especially touch-screen electronic display devices, are usually provided with cover glass, which can protect the display screen from external damage, such as falling, scratching, etc., and can enhance the light transmittance of the display screen to improve the brightness and clarity of the display screen. The cover glass can increase the decorativeness of the display screen and make the display screen more beautiful.

[0049] The cover glass is usually fixed with foam glue. In the prior art, the foam glue is manually applied. However, manual application of the foam glue is inefficient, affects the output per unit time of the production line, and is easy to contaminate the glass, thereby increasing the glass cleaning time.

[0050] Based on this, the prior art provides automatic gluing equipment for applying foam glue to cover glass. However, due to the diverse screen sizes of electronic display devices in actual applications, the prior art equipment is usually only capable of applying foam glue to cover glass of a single size. When the size of the cover glass to be glued with foam glue needs to be changed, some equipment is required to manually change the clamping size and the glue gun head. Some equipment cannot adapt to the requirements of applying foam glue to cover glass of different sizes. However, manual replacement reduces the degree of automation, resulting in low work efficiency, affecting production efficiency. Equipment that cannot adapt to the requirements of applying foam glue to cover glass of different sizes has poor versatility and increases equipment costs.

[0051] In this application Figures 1 to 12 In the figure, some schematic diagrams mark the x-axis direction, y-axis direction and z-axis direction of the automatic foam glue sticking device for display glass in use. For easy understanding, the utility model uses the conveying direction of the cover glass by the automatic foam glue sticking device for display glass as a reference to describe the connection relationship of the various components. The x-axis direction indicates the conveying direction of the glass to be glued, the y-axis direction indicates the direction perpendicular to the x-direction in the horizontal plane, and the z-axis direction indicates the vertical direction.

[0052] like Figure 1-12 As shown, the embodiment of the present application provides an automatic foam adhesive bonding device for display screen glass, comprising: an adhesive bonding platform 100, used to support the glass to be bonded;

[0053] The glue sticking robot 200 is arranged at one side of the glue sticking platform 100, and is used for performing glue sticking operation on the glass to be glued on the glue sticking platform 100. A gun tip quick change assembly 300 is arranged at one side of the glue sticking robot 200, and the gun tip of the glue sticking robot 200 can be replaced by the gun tip quick change assembly 300;

[0054] The visual inspection system includes a visual inspection camera 110 and a camera mounting frame 111. The camera mounting frame 111 is provided with a camera driving mechanism. The visual inspection camera 110 is movably mounted on the camera mounting frame 111 through the camera driving mechanism to adjust the inspection position according to the size of the glass to be glued.

[0055] In the present application, the gluing robot 200 can perform foam glue coating operations on the glass to be glued that is located on the gluing platform 100. The gluing robot 200 can replace the gun tip through the gun tip quick-change assembly 300, and there is no need to manually replace the gun tip, which can improve work efficiency. At the same time, the visual inspection system is movable and can move to the corresponding position according to the size of the glass to be glued to obtain images and then calculate the gluing position, so as to transmit the gluing position data to the gluing robot 200 for gluing operations, thereby achieving adaptation to a variety of glass sizes to be glued, and can achieve foam glue sticking work for all sizes of glass to be glued preset by the equipment. Compared with the situation where the visual inspection system is immovable, the visual inspection system in this solution can move to the best photographing position for each size of glass for visual inspection, and can obtain the most accurate inspection position, making positioning more precise.

[0056] It can be understood that the glue sticking robot in this application refers to an automated mechanical structure that can apply foam glue to a predetermined position. It belongs to the prior art and is not specifically limited in this application. Those skilled in the art can make a reasonable choice based on the specific requirements of the actual foam glue sticking.

[0057] The optimal detection position of the visual inspection camera can be obtained through manual debugging. For example, in equipment that can apply foam glue to 65-inch, 75-inch, and 86-inch display screen glass, an optimal shooting position is set for each of the three sizes of glass. After switching the glass size, the operator switches to the corresponding manufacturing formula through the human-computer interaction interface of the control system, and the visual inspection camera can quickly move to the previously set position. The visual inspection system takes a picture at the set position to calculate the relative position of the glass. The calculated data is transmitted to the robot, and the robot knows the precise position of the glue.

[0058] Reference Figure 1As shown, in an optional embodiment of the present application, the visual inspection system includes four visual inspection cameras 110, and the four visual inspection cameras 110 are respectively arranged corresponding to the four corners of the glue laminating platform 100, and each of the visual inspection cameras 110 can be movably arranged on the corresponding camera mounting frame 111.

[0059] By setting up multiple visual inspection cameras 110, the image information collected by each camera can be integrated, and multiple verifications can be performed to obtain the most accurate visual inspection effect.

[0060] In this embodiment, the visual inspection camera 110 can be movably set, and the movement of the visual inspection camera has two functions. First, the visual inspection camera 110 can adapt to different sizes of foam glue glasses to be pasted by movement. The process of visual inspection is to take pictures of the four corners of the glass to be pasted with foam glue first, and then calculate the position after taking the pictures. The position offset is calculated and assigned to the robot point coordinates, and the robot starts to perform the gluing operation. By setting the visual inspection camera 110 to be movable, it can be moved to the position where each piece of glass needs to be photographed to perform the photographing operation. At the same time, the visual inspection camera 110 can be moved to achieve position avoidance of the gluing robot 200 during the gluing process, that is, the visual inspection camera 110 can move to a position above the plane where the glass is located after completing the photographing action, so as to provide space for the gluing robot 200 to glue and avoid interference with the gluing robot 200.

[0061] Reference Figure 4 , 7 As shown in FIG. 11 , the camera driving mechanism includes a camera driving motor 112 , a power output shaft of the camera driving motor 112 is connected to a lead screw, a slider is provided on the lead screw, and the visual inspection camera 110 is fixedly mounted on the slider.

[0062] Reference Figure 3 As shown, the visual inspection camera 110 described in the present application can be movably arranged to be able to move in the first direction and the second direction at the same time, or, can only move in the first direction or can only move in the second direction. Without changing the size of the foam glue glass to be pasted, all visual inspection cameras 110 can be moved to the preset position for taking pictures by moving only in the first direction or the second direction. When the size of the foam glue glass to be pasted changes, due to the influence of the conveying and positioning implementation method of the automatic foam glue pasting equipment for the display screen glass in this embodiment, when the visual inspection camera 110 moves, some visual inspection cameras (which can be two or three) can reach the preset position by moving only in one of the first direction or the second direction, while some visual inspection cameras 110 (correspondingly two or one) need to move in both the first direction and the second direction.

[0063] For ease of description, the present solution provides an implementation scheme in which the visual inspection camera 110 can move along the first direction and the second direction. When there is no need to implement movement along two directions, the corresponding structure can be cancelled.

[0064] Specifically, the camera mounting bracket 111 described in the embodiment of the present application includes a camera fixed bracket and a camera movable bracket, wherein the camera movable bracket can be installed on the camera fixed bracket so as to be movable along a first direction relative to the camera fixed bracket, and the visual inspection camera 110 can be installed on the camera movable bracket so as to be movable along a second direction relative to the camera movable bracket, wherein the first direction is perpendicular to the second direction.

[0065] Exemplarily, the camera fixing bracket is a bracket structure fixed in a relative position to the glue laminating platform, and is used to support the camera moving bracket to a certain horizontal height. The camera moving bracket is installed on the camera fixing bracket and can move horizontally on the camera fixing bracket. The visual inspection camera is installed on the camera moving bracket, and the visual inspection camera can move on the camera moving bracket.

[0066] It can be understood that the first direction and the second direction are only used to distinguish in description and do not specifically refer to a certain direction.

[0067] For example, in some embodiments of the present application, the first direction is the x direction, and the second direction is the y direction. In other embodiments of the present application, the first direction may be the y direction, and the second direction may be the x direction.

[0068] Reference Fig.11 As shown, in this embodiment, the visual inspection system further includes an exposure light ring 113, and the visual inspection camera 110 is located at the center of the exposure light ring 113, and is electrically connected to the camera drive motor 112 and the controller through wires, and the wires are passed through the tank chain 114. In this embodiment, the exposure light ring 113 can control the illumination range of the light, so that the light is more evenly irradiated on the subject, and can also reduce the noise of the camera, so that the captured image is clearer.

[0069] Tank chain 114 is a wire drag chain, which is used to protect and guide the guide rail system of cables such as cables, hoses, optical fibers, etc. The wire drag chain is composed of a series of chain links, each of which has a guide rail. The cables pass through the guide rail to prevent the cables from being worn, entangled, or falling off during movement. Its specific structure belongs to the conventional technical means in this field, and this application does not specifically limit or describe its structure.

[0070] Preferably, the camera drive motor 112 is a servo motor, which can achieve precise speed control and has the characteristics of high torque accuracy, high position accuracy, fast response speed and high reliability. The movement of the visual inspection camera 110 is achieved by controlling the lead screw slider with the servo motor, which can improve work efficiency and visual inspection accuracy control.

[0071] Meanwhile, the gluing platform 100 described in the present application includes a carrying platform 120, and the carrying platform 120 is used to transport the glass to be glued and to support the glass to be glued so as to facilitate the gluing operation. Figure 7 , 8 As shown, a conveying roller 121 and a positioning roller 122 are provided on the carrying platform 120. The conveying directions of the conveying roller 121 and the positioning roller 122 are perpendicular to each other. The conveying roller 121 and the positioning roller 122 can be raised and lowered along the vertical direction (z direction in the figure).

[0072] The conveying roller 121 and the positioning roller 122 can be used to transport the glass to be glued in different directions during the conveying and positioning process. The rolling friction conveying of the glass to be glued can reduce scratches on the glass surface and ensure the quality of the glass. The conveying roller 121 and the positioning roller 122 are switched by lifting and lowering to avoid the two groups of rollers from affecting each other during the working process.

[0073] Among them, the conveying roller 121 is used for rolling and transporting the glass to be glued along the direction of the conveying line. There are multiple conveying rollers 121, and the multiple conveying rollers 121 are evenly arranged on the supporting platform 120. The conveying rollers 121 may include active rollers and passive rollers. The active rollers are connected to the driving device, which are used to support the glass to be glued and provide friction to make it move along the direction of the conveying line. The passive rollers mainly play the role of supporting the glass to be glued. It can be understood that in order to ensure the stability of the running direction of the glass to be glued during the conveying process, the active rollers are symmetrically arranged along the center line of the conveying direction.

[0074] Furthermore, a movable limit device 123 is provided at the end of the carrying platform 120 along the conveying direction, and the movable limit device 123 is retractable and can switch between a limit position and a non-limit position. The movable limit device 123 is electrically connected to a position detection sensor 124, and the movement of the movable limit device 123 is controlled by a detection signal of the position detection sensor 124.

[0075] The limiting device 123 can limit the glass to be glued in the conveying direction. When the glass to be glued has not reached the gluing station on the conveying line, the movable limiting device 123 is in a retracted state. When the position detection sensor 124 detects that the glass to be glued has reached the gluing station, the limiting device 123 extends out and contacts the glass to be glued, thereby limiting the glass to be glued and restricting the glass to be glued from continuing to move forward along the conveying line direction.

[0076] In the present application, the movable limiting device 123 can be extended and retracted in various directions, for example, it can be extended and retracted up and down in the vertical direction, it can be extended and retracted in the conveying direction of the conveyor line, and it can also be extended and retracted in the horizontal direction perpendicular to the conveyor line.

[0077] Specifically, refer to Figure 8 As shown, a specific structure that can be extended and retracted up and down in the vertical direction (z direction in the figure) is provided in an embodiment of the present application. The limiting device 123 includes a limiting cylinder and a blocking block arranged at the power output end of the limiting cylinder. The limiting cylinder is arranged below the bearing plane of the bearing platform 120, and the power output end is arranged upward. When the limiting device 123 is in the retracted state, the blocking block is also retracted to above the bearing platform 120. When the limiting device 123 is in the extended state, the blocking block at least partially extends to above the bearing plane, so as to form a blockage for the glass to be glued on the bearing platform 120, and limit it in the conveying direction.

[0078] By setting the limiting device 123 to move in the vertical direction, the space below the supporting platform 120 can be fully utilized while achieving the limitation, reducing the space occupied in the length direction (x direction in the figure) and the width direction (y direction in the figure) on the horizontal plane, thereby reducing the overall footprint of the equipment.

[0079] The above has introduced a solution for positioning the glass to be glued by the carrying platform 120 in the conveying direction. The following will continue to introduce a solution for positioning the glass to be glued by the carrying platform 120 in the vertical and conveying directions. Specifically, the carrying platform 120 is provided with glass positioning mechanisms on both sides along its conveying direction. The glass positioning mechanism includes a first positioning component 125 and a second positioning component 126. The first positioning component 125 and the second positioning component 126 are at the same horizontal height and can be relatively movably arranged to clamp and position the glass to be glued on both sides.

[0080] Based on the above description, it can be understood that in the present application, the first positioning component 125 and the second positioning component 126 move in the y direction during the process of clamping and releasing the glass to be glued, and the glass to be glued is located on the moving path of the first positioning component 125 and the second positioning component 126, and the two can move to at least clamp the smallest glass that can be used by the automatic foam glue sticking equipment for display screen glass described in the present application.

[0081] It can be understood that the first positioning component 125 and the second positioning component 126 in the present application are used to clamp and position the glass to be glued on both sides. The first positioning component 125 and the second positioning component 126 need to be relatively arranged on both sides of the glass to be glued. Normally, the glass to be glued is arranged horizontally. Therefore, in the present solution, the first positioning component 125 and the second positioning component 126 are at the same horizontal height. When the first positioning component 125 and the second positioning component 126 are at the same horizontal height and can move relatively, the first positioning component 125 and the second positioning component 126 can clamp the glass to be glued in the horizontal direction.

[0082] In this embodiment, when the positioning function is not performed, the distance between the first positioning component 125 and the second positioning component 126 is greater than the size of the glass to be glued in this direction, so that the glass to be glued can smoothly enter between the two. When the glass to be glued runs into place along the conveying direction, the glass positioning mechanism starts to perform the positioning action, and the first positioning component 125 and the second positioning component 126 approach each other until the glass to be glued is clamped between the two to complete the positioning.

[0083] By setting up a glass positioning mechanism, the glass to be glued has an accurate position in this direction. Through the coordinate correspondence between the glass positioning mechanism and the gluing robot 200, the gluing robot 200 can accurately perform foam glue gluing operations on the glass to be glued.

[0084] The first positioning component 125 and the second positioning component 126 of the present application can be arranged in a variety of ways, for example, referring to Fig.12 As shown, in an optional embodiment of the present application, the first positioning component 125 is fixedly disposed on one side of the carrying platform 120 , and the second positioning component 126 can reciprocate in a direction approaching or moving away from the first positioning component 125 .

[0085] The specific structure continues to refer to Fig.12As shown, the first positioning component 125 is a positioning plate, which is fixedly arranged on one side of the supporting platform 120. The second positioning component 126 includes a positioning motor and a positioning push rod 1261. The positioning push rod 1261 is installed at the power output end of the positioning motor, and its length direction is arranged parallel to the conveying direction.

[0086] When the conveying roller 121 of the glass to be glued moves to the end along the conveying direction, the glass positioning mechanism is used to position it perpendicular to the conveying direction. At this time, the conveying roller 121 descends, so that the glass to be glued is supported by the positioning roller 122, and the second positioning component 126 moves toward the direction close to the first positioning component 125, pushing the glass to be glued close to the first positioning component 125, and the positioning roller 122 rolls and supports the glass to be glued, clamping the glass to be glued between the first positioning component 125 and the second positioning component 126.

[0087] Optionally, the positioning motor described in the present application is a servo motor, and the servo motor is electrically connected to a servo controller, and the servo controller is used to detect torque. When the position of the glass to be glued is tilted, the servo controller detects that the torque is greater than a preset value, and the second positioning component 126 stops working to prevent the glass to be glued from being crushed.

[0088] In a further optional embodiment of the present application, both the first positioning assembly 125 and the second positioning assembly 126 can be movably arranged in a direction perpendicular to the conveying direction. Both the first positioning assembly 125 and the second positioning assembly 126 can be movably arranged, so that the positioning of the glass to be glued can be more rapid and the work efficiency can be improved. It can be understood that when both the first positioning assembly 125 and the second positioning assembly 126 are movable, the first positioning assembly 125 and / or the second positioning assembly 126 can have a torque detection function.

[0089] In another optional embodiment of the present application, referring to Figure 5 , 6 As shown, the first positioning assembly 125 and the second positioning assembly 126 respectively include a positioning cylinder and a positioning rod 1251 arranged at the power output end of the positioning cylinder. The length direction of the positioning rod 1251 is arranged along the conveying direction, and a plurality of positioning blocks 1252 are evenly arranged on the positioning rod 1251.

[0090] Preferably, refer to Figure 8As shown, the carrying platform 120 in the embodiment of the present application is further provided with a vacuum adsorption device 130, and the vacuum adsorption device 130 can adsorb and fix the glass to be glued on the carrying platform 120. The glass to be glued is fixed by the vacuum adsorption device 130, while ensuring the position of the glass to be glued is fixed, and the possibility of causing damage to the glass to be glued is smaller than that of clamping and fixing.

[0091] The working process of the automatic foam glue sticking equipment for glass described in the embodiment of the present application is as follows: the glass to be glued is conveyed on the conveyor line by the conveying roller 121. When the glass to be glued moves to a predetermined position along the conveyor line, the position detection sensor 124 detects that the glass has moved into position, and controls the moving limit device 123 to limit the glass to prevent the glass from continuing to move forward. At the same time, the conveying roller 121 descends to release the support and conveying of the glass, so that the glass to be glued falls on the positioning roller 122. Then, the glass positioning mechanism is started to position the glass to be glued. At this time, the positioning roller 122 plays the role of conveying the glass to be glued.

[0092] When the glass to be glued is positioned, the positioning roller 122 descends, the glass to be glued is placed on the all-metal platform, and the glass is fixed by the vacuum adsorption device 130. After the glass is firmly fixed, the visual inspection system performs position detection and transmits the detection result to the gluing robot 200, and the gluing robot 200 performs the foam glue application operation.

[0093] The working process of the visual inspection system is to first control the camera to move to the shooting position according to the glass size, take pictures and calculate the position, perform secondary position calculation for each point, calculate the position offset and assign it to the point coordinates of the glue sticking robot 200, and the glue sticking robot 200 starts to perform the glue sticking operation.
