Description

Technical Field

[0001] The utility model relates to the field of automated assembly, and in particular to a high-speed screen assembly device for electronic products, wherein the electronic products include mobile phones, tablets and other electronic products involving frame and screen assembly. Background Art

[0002] Typically, the assembly process of electronic products includes the assembly of the screen, middle frame and back panel, among which the assembly of the screen and the middle frame (ie "screen assembly") requires the highest precision.

[0003] In the traditional screen assembly process, the loading, testing and assembly of the screen and the middle frame have the following shortcomings:

[0004] 1. The equipment design is unreasonable, resulting in bloated equipment and efficiency that cannot meet process requirements;

[0005] Second, the screen assembly accuracy needs to be improved, and the defective rate can never be effectively reduced;

[0006] 3. It is impossible to achieve high-speed screen assembly, and the overall rhythm cannot be improved due to connection problems between the various processes.

[0007] Therefore, how to solve the above-mentioned deficiencies in the prior art has become a topic to be studied and solved in the present invention. Summary of the invention

[0008] The utility model aims to provide a high-speed screen assembly device for electronic products.

[0009] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0010] A high-speed screen assembly device for electronic products, comprising:

[0011] A middle frame loading module, the middle frame loading module comprising a first grabbing mechanism for grabbing the middle frame on the middle frame loading station to a middle frame carrier; the middle frame carrier is arranged on a carrier transmission mechanism and is driven by the carrier transmission mechanism to move horizontally to a group of screen stations;

[0012] A screen loading module, the screen loading module comprising a second grabbing mechanism for grabbing the screen on the screen loading station onto a screen carrier, and a third grabbing mechanism is also provided corresponding to the screen carrier, the third grabbing mechanism is provided corresponding to a photo detection module;

[0013] A photo detection and screen assembly module, which includes an upper camera module, which is arranged above the middle frame carrier in the screen assembly station and is used to shoot the middle frame; the screen is driven by the third gripping mechanism to move between the upper camera module and the screen assembly station to shoot the screen, and then the screen is driven to adjust its position and descend to combine with the middle frame; wherein the third gripping mechanism at least drives the screen to perform translation along the x-axis, y-axis, and z-axis and rotation around the z-axis.

[0014] The utility model relates to the assembly of a product middle frame and a screen, but does not relate to the assembly of a back plate.

[0015] According to a further technical solution, multiple groups of middle frame carriers and screen assembly stations can be set. The middle frames are grasped into each middle frame carrier one by one through the rhythm control of the first grasping mechanism, and each middle frame carrier is driven and moved to its corresponding screen assembly station.

[0016] According to a further technical solution, the number of screen carriers can be set to be consistent with the number of screen assembly stations. The screens can be grabbed into each screen carrier one by one through the rhythm control of the second gripping mechanism, and the screens can be grabbed one by one through the rhythm control of the third gripping mechanism for position detection and position compensation, and then placed on the middle frame in each screen assembling station to realize screen assembly.

[0017] According to a further technical solution, the first gripping mechanism is slidably arranged on an x-axis translation track, and the middle frame carrier is located on one side of the middle frame loading station in the x-axis direction;

[0018] The second gripping mechanism is slidably disposed on the x-axis translation track, and is arranged on both sides of the x-axis translation track with the first gripping mechanism, and the screen carrier is located on one side of the screen loading station in the x-axis direction;

[0019] The third grabbing mechanism is slidably disposed on the x-axis translation track and is located on one side of the second grabbing mechanism in the x-axis direction.

[0020] Each gripping mechanism may be a vacuum adsorption component.

[0021] According to a further technical solution, a first loading and conveying mechanism is provided at the middle frame loading station, such as a first horizontal conveyor belt arranged along the y-axis direction; a second loading and conveying mechanism is provided at the screen loading station, such as a second horizontal conveyor belt arranged along the y-axis direction; and the carrier conveying mechanism is a conveying track arranged along the y-axis direction.

[0022] According to a further technical solution, the middle frame carrier includes a lower die seat and at least one pair of pressure rod assemblies;

[0023] The lower die base has a positioning groove corresponding to the outer contour of the middle frame;

[0024] The pressure rod assembly includes a pressure rod and an elastic member. The pressure rod is driven to rotate relative to the lower mold base, and the pressure head of the pressure rod is arranged above the positioning groove of the lower mold base. The first end of the elastic member acts on the pressure rod, and the second end acts indirectly or directly on the lower mold base, and keeps the pressure head of the pressure rod in a tendency to press downward toward the positioning groove.

[0025] The lower end of the pressure rod is transmission-set and rollingly matched with the ejection end of a cylinder. When the screen is not combined with the middle frame, the cylinder drives the pressure rod to rotate, and the pressure rod overcomes the tension of the spring to lift the pressure head at the upper end of the pressure rod backward. At this time, the pressure head is not located above the positioning groove; when the screen is combined with the middle frame, the cylinder cancels the thrust on the pressure rod, and the spring resumes the push on the upper end of the pressure rod, forcing the pressure head to press the screen and the middle frame in the lower die seat.

[0026] According to a further technical solution, the middle frame carrier also includes an upper mold cover, which is driven to open and close relative to the lower mold base, and when closed, it presses the screen and the middle frame located in the lower mold base.

[0027] According to a further technical solution, the photo detection and screen assembly module also includes a lower camera module, which is located on one side below the screen assembly station; the third driving mechanism grabs the screen and moves it to the top of the lower camera module to shoot the cables below the screen.

[0050] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0051] Embodiment: The present invention will be clearly described below with diagrams and detailed descriptions. After understanding the embodiments of the present invention, any person skilled in the art can make changes and modifications based on the techniques taught by the present invention without departing from the spirit and scope of the present invention.

[0052] The terms used herein are only for describing specific embodiments and are not intended to be limiting of the present invention. Singular forms such as "a", "this", "here", "this" and "the" as used herein also include plural forms.

[0053] See attached Figure 1 As shown, Figures 1 to 5 As shown, the high-speed screen assembly equipment of the utility model includes a middle frame loading module, a screen loading module, and a photo detection and screen assembly module.

[0054] The middle frame loading module includes a first grabbing mechanism 8 for grabbing the middle frame 1 on the middle frame loading station A onto a middle frame carrier 2; the middle frame carrier 2 is arranged on a carrier transmission mechanism, and is driven by the carrier transmission mechanism to move horizontally to a group of screen stations B. Among them, multiple groups of middle frame carriers 2 and group screen stations B can be set, and the middle frames 1 are grabbed into each middle frame carrier 2 one by one through the beat control of the first grabbing mechanism 8, and each middle frame carrier 2 is driven to move to the corresponding group screen station B.

[0055] The screen loading module includes a second grabbing mechanism 9 for grabbing the screen 3 on the screen loading station C onto a screen carrier 4, and a third grabbing mechanism 10 is also provided corresponding to the screen carrier 4, and the third grabbing mechanism 10 is provided corresponding to a photo detection module. Among them, the number of screen carriers 4 can be set to be consistent with the number of screen assembly stations B, and the screens 3 are grabbed into each screen carrier 4 one by one through the beat control of the second grabbing mechanism 9, and the screens 3 are grabbed one by one through the beat control of the third grabbing mechanism 10 for position detection and position compensation, and then placed on the middle frame 1 in each screen assembly station B for screen assembly.

[0056] In this embodiment, the above-mentioned beat control can be realized by program setting of the host computer. Since the specific control principles and methods belong to the existing technology well known to technical personnel in this field, they will not be elaborated in this case.

[0057] Preferably, the middle frame loading station A is provided with a first loading and conveying mechanism, such as a first horizontal conveyor belt 5 arranged along the y-axis direction. The screen loading station C is provided with a second loading and conveying mechanism, such as a second horizontal conveyor belt 6 arranged along the y-axis direction. The carrier conveying mechanism is a conveying track 7 arranged along the y-axis direction.

[0058] Preferably, the first gripping mechanism 8 is slidably disposed on an x-axis translation track 11, and the middle frame carrier 2 is located on one side of the middle frame loading station A in the x-axis direction; the second gripping mechanism 9 is slidably disposed on the x-axis translation track 11, and is arranged on both sides of the x-axis translation track 11 with the first gripping mechanism 8, and the screen carrier 4 is located on one side of the x-axis direction of the screen loading station C; the third gripping mechanism 10 is slidably disposed on the x-axis translation track 11, and is located on one side of the second gripping mechanism 9 in the x-axis direction. Each gripping mechanism can be a vacuum adsorption component.

[0059] The photo detection and screen assembly module includes an upper camera module 12 (which may include multiple cameras), which is arranged above the middle frame carrier 2 in the screen assembly station B and is used to implement the shooting of the middle frame 1; the screen 3 is driven by the third gripping mechanism 10 to move between the upper camera module 12 and the screen assembly station B to implement the shooting of the screen 3, and drive the screen 3 to descend and combine with the middle frame 1; wherein the third gripping mechanism 10 at least drives the screen 3 to perform translation including x-axis, y-axis, and z-axis and rotation around the z-axis, so as to adjust the posture of the screen 3 as accurately as possible so that it is accurately aligned with the middle frame 1 in the screen assembly station B. The translation of the x-axis can be achieved by the x-axis translation track 11 (or by its own x-axis cylinder), the translation of the y-axis and z-axis can be achieved by the y-axis cylinder and the z-axis cylinder respectively, and the rotation around the z-axis can be achieved by a rotating motor. Since such a driving mechanism and driving principle are both mature existing technologies and are well known to those skilled in the art, they will not be described in detail in this case. If you do not care about the cost, you can directly use a multi-axis manipulator to adjust the position of the screen 3.

[0060] Preferably, the photo detection and screen assembly module also includes a lower camera module 13, which is located on one side below the screen assembly station B; the third driving mechanism 10 grabs the screen 3 and moves it to the top of the lower camera module 13 to shoot the cables below the screen 3.

[0061] In this embodiment, the number of the upper camera modules 12 and the lower camera modules 13 is consistent with the number of the screen assembly stations B.

[0062] Preferably, Figures 6 to 11 As shown, the middle frame carrier 2 includes a lower mold base 14 and at least one pair of pressure rod assemblies.

[0063] The lower die base 14 has a positioning groove corresponding to the outer contour of the middle frame 1 .

[0064] The pressure rod assembly includes a pressure rod 16 and an elastic member (such as a spring 17). The pressure rod 16 is driven to rotate relative to the lower die base 14, and the pressure head 18 of the pressure rod 16 is arranged above the positioning groove of the lower die base 14; the first end of the spring 17 acts on the pressure rod 16, and the second end acts indirectly or directly on the lower die base 14, so that the pressure head 18 of the pressure rod 16 maintains a tendency to press downward toward the positioning groove.

[0065] The lower end of the pressure rod 16 is transmission-set and rollingly matched with the ejection end of a cylinder (not shown in the figure). When the screen 3 is not combined with the middle frame 1, the cylinder drives the pressure rod 16 to rotate, and the pressure rod 16 overcomes the tension of the spring 17 to lift the pressure head 18 at the upper end of the pressure rod 16 backward. At this time, the pressure head 18 is not located above the positioning groove; when the screen 3 is combined with the middle frame 1, the cylinder cancels the thrust on the pressure rod 16, and the spring 17 resumes the push on the upper end of the pressure rod 16, forcing the pressure head 18 to press the screen 3 and the middle frame 1 in the lower mold base 14.

[0066] It also includes an upper mold cover 19, which is driven to open and close horizontally relative to the lower mold base 14, and when closed, it presses the screen 3 and the middle frame 1 located in the lower mold base 14, and completes the combination of the screen 3 and the middle frame 1 by maintaining pressure and waiting for the glue to completely solidify, and then unloading is carried out.

[0067] The panel assembly equipment further includes a reflux mechanism located below the panel assembly station B, which is used to reflux the empty middle frame carrier 2 after unloading to the middle frame loading station A.

[0068] The high-speed screen assembly process corresponding to the utility model equipment includes:

[0069] The middle frame and screen loading process is used to load the middle frame and screen respectively;

[0070] The middle frame and screen position detection process is used to take photos and detect the spatial positions of the middle frame and the screen respectively, and calculate the compensation amount of the screen for position adjustment;

[0071] The screen position adjustment process is used to adjust the spatial position of the screen according to the compensation amount calculated in the position detection process, so that the outline of the screen is accurately aligned with the outline of the screen joint of the middle frame in the z-axis direction;

[0072] The assembly process of the screen and the middle frame is used to assemble the adjusted screen onto the middle frame along the z-axis.

[0073] The process of detecting the position of the middle frame and the screen also includes taking a photo of the bottom cable of the screen through the lower camera module, moving the screen according to the position data of the screen cable so that the screen cable passes through the middle frame, and then taking a photo of the screen outline through the upper camera module to calculate the compensation amount. With this design, it can be ensured that after the screen position adjustment process, the screen can not only ensure the precise alignment of the outline and the middle frame, but also the cable is passed through the inside of the middle frame.

[0074] Before the process starts, pre-glue can be applied to the joint of the middle frame corresponding to the screen.

[0075] After the assembly process of the screen and the middle frame, the screen and the middle frame are kept in a pressed state to ensure the bonding degree between the two.

[0076] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
