Description

Technical Field

[0001] This invention relates to the field of display screen processing technology, and more specifically, to a parts assembly apparatus and assembly process for display screen production. Background Technology

[0002] A computer monitor is an output device used to display information processed by a computer. It presents content by converting electrical signals into visible light. In recent years, with technological advancements and innovations, manufacturers have designed curved displays to improve user experience and visual effects, and enhance user immersion. To reduce visual distortion, curved displays increase the degree of curvature. A greater degree of curvature makes the distance between the screen edge and the user's eyes more consistent, providing a more natural visual experience.

[0003] When assembling a curved display screen, to facilitate bending, the backlight unit and the curved front cover are first assembled. Next, the main control board and power board are fixed to the backlight unit, and all circuits are connected to form the display module. Finally, the curved back cover and the display module are assembled. In existing technology, when assembling the curved back cover and the display module, the display module is placed on a support station. To improve assembly efficiency and avoid damage to the curved back cover, a suction nozzle with negative pressure is used to position the curved back cover. Then, the curved back cover is transferred above the display module, allowing it to snap into place. Finally, screws or other fasteners are used to secure the curved back cover and the display module together.

[0004] However, the existing technologies mentioned above still have shortcomings. Curved displays with different radii of curvature have different degrees of curvature. When assembling curved back covers of different batches and specifications, the use of a suction nozzle for pneumatic adsorption to position the curved back cover cannot ensure a tight fit between the suction nozzle and the curved back cover. The inaccurate positioning of the curved back cover during the assembly process leads to the inability to snap the curved back cover onto the display module, reducing assembly efficiency and resulting in less than ideal performance. Summary of the Invention

[0005] The present invention provides a component assembly device and assembly process for display screen production. The problem to be solved is that existing component assembly devices for display screen production have different degrees of curvature for curved display screens with different radii of curvature. When assembling curved back covers of different batches and specifications, the use of a suction nozzle for pneumatic adsorption to position the curved back cover cannot ensure a tight fit between the suction nozzle and the curved back cover. The positioning of the curved back cover during the assembly process is inaccurate, resulting in the inability to snap the curved back cover onto the display module, reducing assembly efficiency and resulting in unsatisfactory performance.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a parts assembly device for display screen production, including a feeding mechanism, the feeding mechanism including a first conveyor belt and a second conveyor belt, the first conveyor belt being used to transport display modules, the second conveyor belt being used to transport arc-shaped back cover plates, a transfer mechanism being provided between the first conveyor belt and the second conveyor belt, the transfer mechanism including a robotic arm, the execution end of the robotic arm being provided with a positioning component;

[0007] The positioning component includes a positioning seat, on which an air extraction pipe is slidably mounted. An elastic element is provided between the positioning seat and the air extraction pipe. A negative pressure device is connected to the top of the air extraction pipe, and an air nozzle is provided at the bottom of the air extraction pipe. The robotic arm drives the positioning component to move above the arc-shaped rear cover plate. The positioning seat moves toward the arc-shaped rear cover plate, causing the air nozzle to fit against the surface of the arc-shaped rear cover plate. By activating the negative pressure device, negative pressure is generated inside the air extraction pipe, and the air nozzle is positioned on the arc-shaped rear cover plate.

[0008] In a preferred embodiment, the positioning assembly further includes a hollow sleeve, which is fixedly disposed within the positioning seat. A baffle is fixedly disposed on the air extraction pipe, and the baffle contacts the top of the hollow sleeve. An elastic element is disposed between the baffle and the top inner wall of the positioning seat.

[0009] In a preferred embodiment, a connecting seat is fixedly provided on the extraction pipe, and the connecting seat is slidably disposed inside the hollow sleeve, with the extraction pipe and the hollow sleeve being slidably disposed together.

[0010] In a preferred embodiment, two valves are fixedly connected to the hollow sleeve. The two valves are symmetrically arranged on the hollow sleeve, and a connecting pipe is fixedly connected to the end of the valves away from the hollow sleeve.

[0011] In a preferred embodiment, a sealing mechanism is provided inside the suction pipe. The sealing mechanism includes a movable seat, which is slidably disposed inside the suction pipe. An air hole is provided on the movable seat. A sealing seat is fixedly disposed inside the suction pipe. The air hole is adapted to the sealing seat. An elastic element is provided between the movable seat and the inner wall of the suction pipe.

[0012] In a preferred embodiment, the transfer mechanism includes a linear driver located between conveyor belt one and conveyor belt two, with a rotating seat fixedly mounted on the output shaft of the linear driver, and a robotic arm rotatably mounted on the rotating seat.

[0013] In a preferred embodiment, the robotic arm's execution end is provided with an angle adjustment mechanism, which includes a fixed base. The fixed base is fixedly disposed with the robotic arm's execution end. A rotary driver is fixedly disposed on the fixed base. An auxiliary base is fixedly disposed on the output shaft of the rotary driver. The auxiliary base is fixedly disposed with a positioning base.

[0014] In a preferred embodiment, a limiting seat is fixedly installed inside the extraction pipe. The limiting seat is located below the sealing seat and is adapted to the bottom of the movable seat.

[0015] In a preferred embodiment, a guide shaft is fixedly provided on the limiting seat, the guide shaft is vertically provided on the limiting seat, and the movable seat is slidably sleeved on the guide shaft.

[0016] An assembly process for a parts assembly apparatus for display screen manufacturing includes the following steps:

[0017] Step 1: Place the display module on conveyor belt 1, and place the curved back cover on the curved back cover;

[0018] Step 2: The output end of the linear actuator drives the robotic arm to move horizontally, and the actuator of the robotic arm drives the positioning seat to move directly above the arc-shaped rear cover. Then, the actuator of the robotic arm drives the positioning seat to move toward the arc-shaped rear cover.

[0019] Step 3: The air nozzles contact the surface of the curved rear cover. As the positioning seat continues to move downward, the elastic element is squeezed and deformed. When all the air nozzles are tightly fitted with the curved rear cover, the positioning seat no longer moves downward.

[0020] Step 4: Start the negative pressure device to generate negative pressure in the suction pipe, position the air nozzle on the arc-shaped back cover, and then move the arc-shaped back cover above the display module by moving the positioning seat. Then assemble the arc-shaped back cover and the display module.

[0021] The beneficial effects of this invention are as follows:

[0022] 1. By setting a positioning component, the positioning seat moves toward the arc-shaped rear cover plate. Under the action of the elastic force of the elastic element, it ensures that the air nozzle can fit tightly with the arc-shaped rear cover plate. It can assemble arc-shaped rear cover plates with different curvature specifications and achieve a stable positioning effect, which improves the accuracy of the rear cover plate in the assembly process and further improves the assembly efficiency.

[0023] 2. By setting up a sealing mechanism, if the air nozzle and the arc-shaped rear cover cannot achieve a sealing effect due to the presence of the groove, the air hole and the sealing seat will engage when the moving seat is driven to move under the action of negative pressure, thereby blocking the air extraction pipe, which improves the response speed of the negative pressure system and extends the service life of the negative pressure equipment.

[0035] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0036] Refer to the instruction manual appendix Figures 1 to 6 A component assembly device for display screen production includes a feeding mechanism 1, which includes a first conveyor belt 11 and a second conveyor belt 12. The first conveyor belt 11 is used to transport a display module a1, and the second conveyor belt 12 is used to transport an arc-shaped back cover plate b1. A transfer mechanism 2 is provided between the first conveyor belt 11 and the second conveyor belt 12. The transfer mechanism 2 includes a robotic arm 23, and the execution end of the robotic arm 23 is provided with a positioning component 3.

[0037] The positioning component 3 includes a positioning seat 31, on which an air extraction pipe 33 is slidably disposed. An elastic element 34 is disposed between the positioning seat 31 and the air extraction pipe 33. A negative pressure device is connected to the top end of the air extraction pipe 33, and an air nozzle 331 is disposed at the bottom end of the air extraction pipe 33. The robotic arm 23 drives the positioning component 3 to move above the arc-shaped rear cover plate b1. The positioning seat 31 moves toward the arc-shaped rear cover plate b1 so that the air nozzle 331 fits against the surface of the arc-shaped rear cover plate b1. By activating the negative pressure device, a negative pressure is generated in the air extraction pipe 33, and the air nozzle 331 positions the arc-shaped rear cover plate b1.

[0038] It should be noted that the negative pressure device is a vacuum pump. The display module a1 consists of a backlight unit, an arc-shaped front cover, a main control board, a power board, and connecting lines. After assembling the arc-shaped rear cover b1 with the display module a1, a complete curved display screen is obtained.

[0039] It should also be noted that both conveyor belt 11 and conveyor belt 212 include support frames, on which two drive rollers are rotatably mounted. The two drive rollers are connected to the same conveyor belt. A motor is fixedly mounted on the support frame, and the motor's output shaft is fixedly mounted to the drive rollers. The conveying surface of conveyor belt 11 is provided with an arched flexible support seat. After the display module a1 is placed on the conveyor belt of conveyor belt 11, the arched flexible support seat fits tightly against the arc-shaped surface of the display module a1, preventing damage to the display module a1 during transport. Both conveyor belt 11 and conveyor belt 212 are equipped with corresponding limiters and positioners. As the conveyor belt transports the display module a1 and the arc-shaped back cover plate b1, when the display module a1 and the arc-shaped back cover plate b1 move to the designated position, the limiters and positioners can accurately position the display module a1 and the arc-shaped back cover plate b1 on the conveyor belt. This is mature existing technology and will not be elaborated further here.

[0040] Furthermore, a robotic arm is provided on the edge of the conveyor belt 11, and an automatic screw-driving mechanism is provided on the execution end of the robotic arm. When the display module a1 and the arc-shaped back cover b1 are joined together, the automatic screw-driving mechanism can fix the display module a1 and the arc-shaped back cover b1 together by means of screw thread connection, so that the connection between the display module a1 and the arc-shaped back cover b1 is tighter. The robotic arm and the automatic screw-driving mechanism are mature existing technologies and will not be described in detail here.

[0041] The specific implementation scenario is as follows: Display module a1 is placed on conveyor belt 11, and curved rear cover plate b1 is placed on conveyor belt 12. The conveyor belts move display module a1 and curved rear cover plate b1 to designated positions. First, robotic arm 23 drives positioning seat 31 to move directly above curved rear cover plate b1. Then, robotic arm 23 drives positioning seat 31 to move towards curved rear cover plate b1, i.e., drives positioning seat 31 to move vertically downwards. When positioning seat 31 moves to a certain extent, due to the curvature of curved rear cover plate b1 (i.e., the upper surfaces of curved rear cover plate b1 are not at the same horizontal level), the middle part of the air nozzle 331 will first contact the middle surface of curved rear cover plate b1. As positioning seat 31 continues to move downwards, more and more air nozzles 331 will contact the surface of curved rear cover plate b1. Correspondingly, elastic element 34 deforms under the pressure, and simultaneously, the suction pipe 3... 3. A downward reaction force is generated. When all the air nozzles 331 are in contact with the surface of the arc-shaped rear cover plate b1, the corresponding elastic elements 34 on the suction pipe 33 are deformed due to the external force, and a downward force is generated on the suction pipe 33, so that the air nozzles 331 can be tightly in contact with the surface of the arc-shaped rear cover plate b1. Then, the negative pressure device is turned on, and the negative pressure device draws air from the suction pipe 33 to form a negative pressure inside the suction pipe 33. After the negative pressure is formed inside the air nozzles 331, they are more tightly in contact with the arc-shaped rear cover plate b1. Then, the positioning seat 31 moves upward, and the air nozzles 331 can lift the arc-shaped rear cover plate b1 and move synchronously with the positioning seat 31. After the positioning seat 31 moves above the display module a1, the arc-shaped rear cover plate b1 is aligned with the display module a1 and the arc-shaped rear cover plate b1 is pressed onto the display module a1. The display module a1 and the arc-shaped rear cover plate b1 are connected together by the automatic screw-driving mechanism. Compared with existing technologies, when producing different batches of curved displays, there is no need to adjust the production line according to the curvature and size of the curved display. The positioning component 3 can adaptively adjust and stably position displays with different curvatures, thus improving production efficiency.

[0042] Refer to the instruction manual appendix Figures 4 to 6When the air nozzle 331 is tightly fitted to the surface of the arc-shaped rear cover b1, during the upward movement of the positioning seat 31, if some of the suction pipes 33 slide against the positioning seat 31, some of the suction pipes 33 will be unable to provide traction force to the arc-shaped rear cover b1, causing the effective traction force to be concentrated on some of the suction pipes 33, which may easily damage the suction pipes 33. Therefore, in order to ensure that all suction pipes 33 can provide effective traction force to the arc-shaped rear cover b1 during the lifting process, the positioning assembly 3 specifically includes a hollow sleeve 32. The hollow sleeve 32 is fixedly installed inside the positioning seat 31, and a baffle is fixedly installed on the suction pipe 33. The baffle is in contact with the top of the hollow sleeve 32, and the elastic element 34 is installed between the baffle and the top inner wall of the positioning seat 31. A connecting seat 332 is fixedly installed on the suction pipe 33. The connecting seat 332 is slidably installed inside the hollow sleeve 32. The suction pipe 33 and the hollow sleeve 32 are slidably installed together. Two valves 321 are fixedly connected to the hollow sleeve 32. The two valves 321 are symmetrically arranged on the hollow sleeve 32. The end of the valve 321 away from the hollow sleeve 32 is fixedly connected to a connecting pipe.

[0043] It should be noted that the elastic element 34 is set as a spring, with the top end of the spring fixedly set to the top inner wall of the positioning seat 31, and the bottom end of the spring fixedly set to the top of the baffle.

[0044] It should also be noted that the connecting seat 332 divides the internal space of the hollow sleeve 32 into two independent cavities, so as to... Figure 5 For example, the cavity located in the upper half of the connecting seat 332 is cavity one, and the cavity located in the lower half of the connecting seat 332 is cavity two. Due to the presence of the connecting seat 332, cavity one and cavity two cannot be connected. Valve 321 is set as a solenoid valve. The end of the connecting pipe away from valve 321 is fixedly connected to a pump. Gas or liquid is transported into the hollow sleeve 32 through the pump.

[0045] In this embodiment, after the air nozzle 331 contacts the arc-shaped rear cover plate b1, as the positioning seat 31 continues to move towards the arc-shaped rear cover plate b1, the connecting seat 332 slides upward within the hollow sleeve 32. The space in cavity one gradually decreases, while the space in cavity two gradually increases. During the upward sliding of the hollow sleeve 32, gas or liquid medium is introduced into cavity two through valve 321. Simultaneously, during the upward sliding of the hollow sleeve 32, gas or liquid medium is discharged from cavity one through the corresponding valve 321. When the connecting seat 332 moves to the designated position within the hollow sleeve 32, the valve is closed. 321. Since water or liquid medium is present in both cavity one and cavity two, the pressure difference between cavity one and cavity two is used to position the connecting seat 332. Even if the connecting seat 332 is subjected to an external force in the vertical direction, it cannot be displaced in the vertical direction, thus realizing the working principle of the "cylinder" output shaft moving. Then, negative pressure is generated in the suction pipe 33, which positions the arc-shaped rear cover plate b1 through valve 321. During the upward movement of the positioning seat 31, since the suction pipe 33 is positioned, each suction pipe 33 can provide traction force to the arc-shaped rear cover plate b1, thus extending the service life of the suction pipe 33.

[0046] Refer to the instruction manual appendix Figure 7 and Figure 8 To reduce the use of power sources and lower the operating costs and maintenance difficulty of the equipment, the tops of multiple suction pipes 33 are connected to the same negative pressure device. Activating one negative pressure device will generate negative pressure in all suction pipes 33. Some curved e-sports display products, to make the curved back cover b1 more aesthetically pleasing, will have grooves cut into the surface of the curved back cover b1, which, together with LED light strips, gives the curved back cover b1 a stronger visual impact. When all the air nozzles 331 are tightly fitted to the surface of the curved back cover b1, and the air nozzles 331 come into contact with the grooves on the curved back cover b1, because the grooves cannot form a closed state with the air nozzles 331, the negative pressure device... After startup, the corresponding air nozzle 331 continuously draws air but fails to form a negative pressure, causing a delay in the response of the entire negative pressure system. Furthermore, the negative pressure equipment continues to operate without effective negative pressure, leading to overload and overheating, thus reducing its lifespan. To address these issues, a sealing mechanism 4 is specifically installed within the suction pipe 33. This sealing mechanism 4 includes a movable seat 41, which is slidably disposed within the suction pipe 33. The movable seat 41 has an air hole 411. A sealing seat 42 is fixedly installed within the suction pipe 33, with the air hole 411 and sealing seat 42 fitting together. An elastic element 43 is provided between the movable seat 41 and the inner wall of the suction pipe 33. A limiting seat is fixedly installed within the suction pipe 33, located below the sealing seat 42, and fitting with the bottom of the movable seat 41. A guide shaft is fixedly installed on the limiting seat, vertically positioned thereon, and the movable seat 41 is slidably sleeved on the guide shaft.

[0047] It should be noted that the elastic element 43 is set as a spring, with the bottom end of the spring fixedly set to the top of the movable seat 41 and the top end of the spring fixedly set to the inner wall of the suction pipe 33.

[0048] It should also be noted that after the air nozzle 331 is in contact with the surface of the arc-shaped rear cover b1, the negative pressure device is activated. The negative pressure device draws air from the suction pipe 33, creating a negative pressure between the suction pipe 33 and the air nozzle 331. If there is a groove at the contact point between the air nozzle 331 and the arc-shaped rear cover b1, a seal cannot be formed between the air nozzle 331 and the arc-shaped rear cover b1. As the negative pressure device continues to operate, the suction pipe 33 will draw in external air through the air hole 411. The negative pressure suction flow rate is greater than the air flow rate through the air hole 411, resulting in a pressure difference between the upper and lower parts. The moving seat 41 is pushed upward by the external pressure. The movement of the moving seat 41 will compress the elastic element 43. When seat 41 moves to a certain position, sealing seat 42 will engage with air hole 411 to seal air hole 411. Under negative pressure conditions, the position of air hole 411 will remain unchanged, achieving the effect of sealing a single independent suction pipe 33. When it is necessary to release the positioning of the arc-shaped rear cover plate b1, the negative pressure equipment is turned off. When air is introduced into the suction pipe 33, due to the disappearance of negative pressure inside the suction pipe 33, the moving seat 41 is reset under the action of the elastic force of elastic element 43. Even if the air nozzle 331 contacts the groove on the arc-shaped rear cover plate b1, it can actively seal the suction pipe 33, prevent the negative pressure equipment from continuously sucking air, and extend the service life of the negative pressure equipment.

[0049] Refer to the instruction manual appendix Figures 1 to 3 To facilitate the clamping of the arc-shaped rear cover plate b1, the transfer mechanism 2 specifically includes a linear driver 21, which is located between the first conveyor belt 11 and the second conveyor belt 12. A rotating seat 22 is fixedly mounted on the output shaft of the linear driver 21, and the robotic arm 23 is rotatably mounted on the rotating seat 22.

[0050] It should be noted that the linear driver 21 is a linear motor, and the rotating seat 22 is rotatably mounted on the output shaft of the linear motor. The movement of the output shaft of the linear motor drives the robotic arm 23 to move horizontally.

[0051] Refer to the instruction manual appendix Figure 9When assembling the display module a1 and the arc-shaped back cover b1, for assembly efficiency, matching fasteners are usually provided on the display module a1 and the arc-shaped back cover b1. The display module a1 and the arc-shaped back cover b1 are first fastened and positioned by the fasteners, and then finally positioned by screws. After the air extraction pipe 33 grabs and transports the arc-shaped back cover b1, if the arc-shaped back cover b1 is directly fastened onto the display module a1, all sides of the display module a1 and the arc-shaped back cover b1 need to be perfectly matched, which is difficult to assemble. To solve this problem, specifically, the execution end of the robotic arm 23 is provided with an angle adjustment mechanism 5. The angle adjustment mechanism 5 includes a fixed seat 51, which is fixedly set to the execution end of the robotic arm 23. A rotation driver 52 is fixedly set on the fixed seat 51, and an auxiliary seat 53 is fixedly set on the output shaft of the rotation driver 52. The auxiliary seat 53 is fixedly set to the positioning seat 31.

[0052] It should be noted that the rotary driver 52 is a motor, and the output shaft of the motor is fixedly mounted to the auxiliary seat 53.

[0053] It should also be noted that when the exhaust pipe 33 positions the arc-shaped back cover b1 and moves it above the display module a1, the output shaft of the drive rotation driver 52 drives the positioning seat 31 to rotate, so that one side of the arc-shaped back cover b1 fits against one side of the display module a1. Then, as the output shaft of the drive rotation driver 52 rotates, it drives the positioning seat 31 to rotate, so that the display module a1 and the arc-shaped back cover b1 gradually fit together completely, reducing the difficulty of assembly.

[0054] Refer to the instruction manual appendix Figure 10 An assembly process for a parts assembly apparatus for display screen manufacturing specifically includes the following steps:

[0055] Step 1: Place the display module a1 on the conveyor belt 11, and place the arc-shaped back cover plate b1 on the arc-shaped back cover plate b1;

[0056] Step 2: The output end of the linear actuator 21 drives the robotic arm 23 to move horizontally. The execution end of the robotic arm 23 drives the positioning seat 31 to move directly above the arc-shaped rear cover plate b1. Then, the execution end of the robotic arm 23 drives the positioning seat 31 to move toward the arc-shaped rear cover plate b1.

[0057] Step 3: The air nozzle 331 contacts the surface of the arc-shaped rear cover plate b1. As the positioning seat 31 continues to move downward, the elastic element 34 is squeezed and deformed. When all the air nozzles 331 are tightly fitted with the arc-shaped rear cover plate b1, the positioning seat 31 no longer moves downward.

[0058] Step 4: Start the negative pressure device to generate negative pressure in the air extraction pipe 33. The air nozzle 331 positions the arc-shaped back cover b1. Then, the arc-shaped back cover b1 is moved above the display module a1 by the movement of the positioning seat 31. Finally, the arc-shaped back cover b1 and the display module a1 are assembled.

[0059] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
