Description

Technical Field

[0001] The present application relates to the technical field of display production, and in particular to an automatic nail embedding device. Background Art

[0002] In the current injection molding process for some monitor back covers, a key step is integrating four screws into the back cover. Once formed, these screws secure the back cover to the mounting bracket, ensuring a stable and easy-to-install display.

[0003] However, in existing production methods, this step is typically completed manually. Workers manually place the screws on the screw posts in the mold and then start the injection molding machine to form the parts. This method is not only inefficient but also susceptible to human error, such as inaccurate placement and missing screws, which can affect product quality and consistency.

[0004] Furthermore, with the expansion of display production and the acceleration of production pace, manual nail placement can no longer meet the demands of efficient, automated production. Manual operations are not only time-consuming and labor-intensive, but also increase production and labor costs. Furthermore, the uncontrollable nature of manual operations can lead to safety hazards during production.

[0005] In response to the above problems, a kind of automatic nail embedding device is now designed. Utility Model Content

[0028] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0029] An embodiment of the present application provides an automatic nail embedding device, which can solve the problem in the related art that during the injection molding production process of the display back cover, the screw embedding operation is usually performed manually, which affects work efficiency.

[0030] See also Figure 1-Figure 3, an automatic nail embedding device includes: a three-axis linear slide 1 and a forming machine 2, the forming machine 2 includes a male mold 21 and a female mold 22 for injection molding of the back shell of the display, the male mold 21 is provided with four screw columns distributed in a rectangular shape; a manipulator 3 is provided on the three-axis linear slide 1, and the three-axis linear slide 1 is used to drive the manipulator 3 to move along the X, Y and Z axis directions; the manipulator 3 includes a support frame 31, a pneumatic suction cup 32 is provided on one side of the support frame 31, and four accommodating tubes 33 are provided at the other end of the support frame 31, the accommodating tube 33 is used to accommodate screws, and a driving member 34 is provided inside the accommodating tube 33, the driving member 34 is used to push the screws inside the accommodating tube 33 to the corresponding screw columns, and the pneumatic suction cup 32 is used to adsorb the back shell of the display after forming.

[0031] The end of the screw column in the original solution is rounded and fits with the corresponding screw.

[0032] The top of the molding machine 2 is open, allowing the robot 3 to penetrate deeper.

[0033] Initialization and Preparation: First, the screws are sequentially placed into four storage tubes 33 using a screw sorting machine. These tubes 33 are fixed to one end of the support frame 31 of the manipulator 3, ensuring that each screw is stably stored in its corresponding tube. If necessary, artificial bacteria can be used to insert the screws into the storage tubes 33.

[0034] When the male mold 21 and female mold 22 for the injection molding of the display back cover are ready, the three-axis linear slide 1 starts working. It drives the robot 3 to move precisely along the X, Y and Z axes, so that the robot 3 can be accurately positioned at the designated position on one side of the male mold 21. When the robot 3 reaches the designated position, the driving member 34 inside the receiving tube 33 starts working, which pushes the screw inside the receiving tube 33 forward along the pipe until the screw is accurately pushed to the corresponding screw column on the male mold 21. Since the end of the screw column is smooth, it fits in with the screw very smoothly, ensuring that the screw can be firmly fixed to the mold.

[0035] Subsequently, the manipulator 3 is reset, and the screws are pushed into the receiving tubes 33 again via the screw sorting machine. Simultaneously, after the screws are successfully pushed and secured, the injection molding process of the molding machine 2 begins. After the injection molding of the display back cover is completed, the above steps are repeated, and the three-axis linear guide 1 drives the manipulator 3 to re-enter the molding machine 2. As the manipulator 3 moves toward the female mold 22, the pneumatic suction cup 32 begins to operate, generating negative pressure to absorb the formed display back cover, ensuring that the back cover can be stably grasped and lifted by the manipulator 3. When the manipulator 3 is accurately positioned at the designated position on the male mold 21, the driver 34 pushes the screws onto the corresponding screw posts on the male mold 21.

[0036] Finally, the three-axis linear slide 1 drives the manipulator 3 to move again, moves the pneumatic suction cup 32 adsorbing the display back cover to the designated placement position, and then releases the negative pressure in the suction cup to place the display back cover steadily at the designated position.

[0037] By repeating the above steps, the automatic nail embedding operation of the injection molding production of the display rear shell can be realized.

[0038] The coordination of the three-axis linear guide rail 1, support frame 31, receiving tube 3, and driver 34 allows for automatic nail placement in the male mold 21 of the forming machine 2, significantly reducing manual intervention, thereby speeding up production and improving overall production efficiency. Automated production also reduces labor requirements and labor costs. This reduced human intervention also reduces material waste and rework costs caused by operational errors.

[0039] This device reduces manual operation, thereby reducing safety hazards caused by improper operation. At the same time, the precise control and positioning of the manipulator also reduces the risk of equipment damage caused by operational errors.

[0040] The support frame 31 in this embodiment includes a mounting column 311 arranged on the three-axis linear slide 1, and a rotating part 312 is provided at the bottom end of the mounting column 311. The other end of the rotating part 312 is connected to a mounting plate 313. The rotating part 312 is used to drive the mounting plate 313 to rotate, and the mounting plate 313 is N-shaped.

[0041] The support frame 31 is firmly fixed on the three-axis linear slide 1 through the mounting column 311, ensuring that the manipulator 3 can move accurately along the X, Y, and Z axes. The mounting column 311 serves as a bridge connecting the three-axis linear slide 1 and the support frame 31, playing a key supporting and fixing role.

[0042] At the bottom end of support frame 31 is a rotating member 312, a mechanical component capable of generating rotational motion. One end of the rotating member 312 is connected to mounting post 311, and the other end is connected to mounting plate 313. Driven by rotating member 312, mounting plate 313 rotates around the axis of rotating member 312. This design allows for greater flexibility in the operation of manipulator 3, enabling it to adapt to operations at various angles and directions.

[0043] Mounting plate 313 is designed in an N-shape, which not only increases its strength and stability but also provides ample mounting space for components such as the pneumatic suction cup 32 and the receiving tube 33. These components can be mounted on either side of the mounting plate 313 or in appropriate locations to ensure proper function and meet operational requirements.

[0044] Preferably, Figure 3As shown, the rotating member 312 in this embodiment includes a connecting column, a groove is opened at the bottom end of the mounting column 311, one end of the connecting column is arranged inside the groove, and a driving motor is arranged on the mounting column 311. The output shaft of the driving motor is connected to one end of the connecting column and is used to drive the connecting column to rotate.

[0045] Rotating member 312 mainly includes a connecting post, which serves as the core component of the rotation and connects mounting post 311 and mounting plate 313. One end of the connecting post is designed to be inserted into the groove at the bottom end of mounting post 311, which enhances the stability of the connection and ensures smooth rotation.

[0046] The output shaft of the drive motor is tightly connected to one end of the connecting column. The rotation of the drive motor drives the rotation of the connecting column, so that the rotation of the rotating member 312 can be precisely controlled, thereby meeting the flexibility and accuracy requirements of the manipulator 3 during operation.

[0047] In one embodiment, Figure 4 As shown, the pneumatic suction cup 32 includes a suction cup 321 and a connecting tube 322 connected to each other. The other end of the connecting tube 322 extends to the inner side of the mounting plate 313. The other end of the connecting tube 322 is connected to a hose 323. The hose 323 is connected to an external pneumatic control device and is used to control the generation of negative pressure inside the suction cup 321.

[0048] The pneumatic suction cup 32 mainly consists of two parts: a suction cup 321 and a connecting tube 322. The suction cup 321 is the part that actually contacts the rear cover of the display, while the connecting tube 322 serves as a bridge between the suction cup 321 and the pneumatic control device, responsible for transmitting gas.

[0049] The other end of the connecting pipe 322 cleverly extends to the inner side of the mounting plate 313. This design not only avoids direct contact between the connecting pipe 322 and the external environment during operation, reducing the risk of damage, but also makes the overall structure more compact and beautiful.

[0050] The design of hose 323 provides greater flexibility and convenience in connecting the pneumatic suction cup 32 to an external pneumatic control device. Hose 323 is resistant to bending and twisting, ensuring stable and reliable gas transmission. Furthermore, hose 323 acts as a buffer and shock absorber, minimizing damage to the pneumatic suction cup 32 caused by mechanical vibration or impact.

[0051] The pneumatic suction cup 32 operates primarily based on the principle of negative pressure. When an external pneumatic control device pumps air into the suction cup 321 via the hose 323 and connecting tube 322, the air pressure inside the suction cup 321 gradually decreases, creating a negative pressure. This negative pressure allows the suction cup 321 to adhere tightly to the surface of the display's rear case. To release the display's rear case, the external pneumatic control device injects air into the suction cup 321 via the hose 323 and connecting tube 322, raising the air pressure inside the suction cup 321 and releasing the suction effect.

[0052] like Figure 4 As shown, the four accommodating tubes 33 in this embodiment are distributed in a rectangular shape, and the four accommodating tubes 33 are arranged in a one-to-one correspondence with the four screw columns; the accommodating tube 33 is a metal circular tube, and has a cavity inside for accommodating screws.

[0053] The accommodating tube 33 has a chamber inside for accommodating screws to ensure that the screws can be tightly installed therein to avoid shaking or falling off during the transportation and fixing process.

[0054] The four receiving tubes 33 are arranged in a rectangular pattern and correspond one-to-one with the four screw posts. This layout not only ensures that each receiving tube 33 is accurately aligned with a screw post, but also improves the compactness and stability of the overall structure. Furthermore, the rectangular arrangement helps balance the forces acting on the manipulator 3 during operation, reducing operational errors caused by uneven force.

[0055] Specifically, such as Figure 4 As shown, in this embodiment, the driving member 34 includes a push block 341 disposed inside the receiving tube 33, and a cylinder 342 disposed on the mounting plate 313. The piston rod of the cylinder 342 is connected to the push block 341 and is used to drive the push block 341 to move along the length of the receiving tube 33. The mounting plate 313 is provided with a through hole for accommodating the piston rod of the cylinder 342.

[0056] Pushing block 341 is the part of driver 34 that directly contacts the screw. Its shape and size are customized based on the dimensions of the housing tube 33 and the screw. Pushing block 341 fits snugly within the interior of the housing tube 33, ensuring a tight fit and smooth push onto the screw post during the pushing process.

[0057] The piston rod of the cylinder 342 is tightly connected to the pushing block 341 , and the pushing block 341 is driven to move along the length direction of the accommodating tube 33 by the telescopic movement of the cylinder 342 .

[0058] In order to accommodate the piston rod of the cylinder 342 and allow it to expand and contract freely, a through hole is specially provided on the mounting plate 313. The position and size of this through hole are designed according to the layout of the cylinder 342 and the pushing block 341 to ensure that they can fit closely and smoothly complete the pushing action.

[0059] When cylinder 342 receives an external control signal, its piston rod begins to extend and retract. This movement is transmitted to push block 341 via the connector, allowing it to move along the length of housing tube 33. During this movement, push block 341 closely fits the screw and pushes it onto the corresponding screw post.
