Description

Technical Field

[0001] The invention relates to the field of notebook computer production, and in particular to a notebook computer pad strip installation machine. Background Art

[0002] Laptop computers, portable electronic devices with powerful computing capabilities, are widely used in the workplace. To increase portability, laptops are becoming increasingly thinner and lighter. To ensure stability, reduce vibration, and provide heat dissipation during use, two parallel pads are typically installed on the bottom of the laptop, creating a gap between the bottom and the surface on which it is placed. To improve stability and user comfort, the pads are typically arranged in a structure with one higher and one lower, with the lower pad located at the front of the laptop. This creates a certain inclination during use, providing greater stability and easier viewing of the screen. Currently, the installation of these two pads is often done manually during production. A large number of pads are loaded in baskets and placed next to a workstation. Workers manually select the higher and lower pads and install them separately. This manual identification of the pad heights ensures accurate installation, but workers also have to complete the installation process. Due to the labor intensity and reduced accuracy caused by fatigue, production efficiency in this process remains difficult to improve. In mass production, efficiency can only be maintained by adding multiple workstations, but this significantly increases costs. Summary of the Invention

[0003] The present invention aims to provide a laptop pad installation machine to solve the problem that in the prior art, the bottom pads of laptop computers are installed by manual loading and installation. Due to the labor intensity and reduced accuracy after fatigue, the production efficiency of this link is always difficult to improve, and it is difficult to meet the efficiency and cost requirements of mass production processes.

[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a laptop computer pad strip installation machine, including a robotic arm, a loading device and an installation tool, the robotic arm is located between the loading device and the installation tool, the installation tool is used to position the shell to provide a pad strip installation station, the robotic arm is used to grab high and low pad strips from the loading device and transfer them to the installation station for pad strip installation, the loading device includes a base, a vertical motor is fixed in the middle of the base, the motor output shaft is facing upward and a support plate is fixed, a plurality of fan-shaped loading plates are distributed on the support plate around the motor axis, a plurality of strip-shaped loading troughs are arranged side by side on the upper end of the loading plate, the loading troughs are radially distributed outward with the motor axis as the center, and an identification mark is provided on the loading plate outside the end of each loading trough, the identification mark is used to distinguish whether the loading trough should be loaded with high pad strips or low pad strips, and the identification marks marking the high pad strips and low pad strips are set at intervals.

[0005] The principles and advantages of this solution are: in actual application, the loading device continuously moves the pad strips toward the robotic arm in a specific order to load the pad strips; the installation tooling is used to position and clamp the laptop computer case on which the pad strips are to be installed; the robotic arm grabs the pad strips from the loading device through automated control and moves them to the installation tooling, and presses the grabbed pad strips onto the laptop computer case to complete the automated installation of the pad strips. The base in the loading device provides support for the motor from the bottom, and the motor drives the support plate to rotate. The loading plate on the support plate serves as a carrier for the pads, and the loading trough is used to position the loaded pads. The identification marks are used to conveniently and intuitively distinguish whether the loading trough should be placed with high pads or short pads. The radially distributed loading troughs cooperate with the support plate to rotate for loading, which can load pads in large quantities. Multiple separate loading plates can be used for individual small batch loading and then loaded onto the support plate in batches, or continuous loading can be performed during the rotation of the support plate. A certain reserve amount can be retained between loading and pad installation, reserving operation time for loading, and then cooperating with the robot to install the pads. Workers only need to complete the simple operation of loading the pads into the loading trough. The identification marks can improve the workers' loading accuracy, reduce the workers' labor intensity, and improve the work quality. The efficiency of pad loading and installation is greatly improved compared with the existing technology.

[0006] Preferably, as an improvement, a support frame is provided between the base and the support plate, wherein the bottom of the support frame is fixed to the base, and the top of the support frame is rotatably connected to the bottom of the support plate. The support frame can provide support for the support plate so that the support plate can remain stable during rotation.

[0007] Preferably, as an improvement, two positioning slots are provided at the small end of the carrier plate, and positioning posts are provided on the support plate to correspond to the slots. A height limiting block is fixed to the support plate between two adjacent positioning posts, and the bottom surface of the height limiting block can be aligned with the top surface of the carrier plate. The cooperation between the positioning posts and the positioning slots allows for accurate radial positioning of the carrier plate. The height limiting block also limits the carrier plate axially, ensuring axial stability, which helps ensure stable gripping of the backing strip after loading and installation.

[0008] Preferably, as an improvement, the support plate is provided with radial strip holes, with multiple strip holes corresponding to the material loading plate. A push rod is connected to the bottom of the support plate in a radial sliding manner. A through hole is provided in the middle of the material loading plate, and a connecting piece is provided in the through hole, which passes through the strip hole and is fixed to the push rod. The push rod can be manually operated to accurately position the material loading plate on the support plate. The strip holes and the connecting piece guide the movement of the material loading plate. The positioning column, height limit block, and spacer block are used to achieve precise positioning of the material loading plate, thereby ensuring that the loading pad is accurately positioned and ready to be grabbed for installation.

[0009] Preferably, as an improvement, the push rod extends beyond the support plate, and the support frame is provided with a pusher member that can be extended radially along the support plate. The pusher member pushes the push rod, thereby positioning the carrier plate. The pusher member can be electrically or pneumatically actuated. This allows workers to simply place the corresponding pad in the carrier trough, reducing labor intensity, increasing automation, and providing more accurate and reliable positioning of the carrier plate.

[0010] Preferably, as an improvement, spacers are fixed to the support plates between adjacent carrier plates. The spacers can form gaps between adjacent carrier plates, reducing the contact area between the carrier plates and the interaction between the carrier plates, ensuring accurate positioning of the carrier plates and the pads thereon, thereby facilitating accurate grabbing of subsequent installation and removal of materials.

[0011] Preferably, as an improvement, an annular chute is provided at the top of the support frame, wherein a plurality of balls are distributed in the chute, and an annular slide rail is fixed to the bottom of the support plate, wherein the slide rail is inserted into the chute and contacts the balls. In this way, the rotation of the support plate relative to the support frame is more stable, and the rotation of the support plate is more stable and smooth.

[0012] Preferably, as an improvement, a rotation mechanism is provided at the end of the robotic arm, the output end of the rotation mechanism being connected to a mounting base, to which two vertical gripping cylinders are connected side by side, the telescopic ends of the gripping cylinders facing downward and connected to strip-shaped negative pressure suction cups, which are connected to a negative pressure source. In this way, the two gripping cylinders can each drive a negative pressure suction cup downward to absorb a pad under the action of the negative pressure source. The rotation mechanism can be used to switch the negative pressure suction cups during the gripping process and to align the pads on the negative pressure suction cups with the laptop casing on the installation tool during the installation process.

[0013] Preferably, as an improvement, the distance between the two negative pressure suction cups matches the distance between the two pads at the bottom of the laptop housing, so that the captured pads can be aligned more easily and conveniently with the mounting position at the bottom of the laptop housing.

[0014] Preferably, as an improvement, the installation tool includes a positioning plate with a plurality of stoppers provided thereon. The plurality of stoppers enclose a rectangular positioning area for placing the laptop computer case on which the gasket strip is to be installed. The positioning area formed by the stoppers accurately positions the laptop computer case, and the positioning plate provides support. In conjunction with the robotic arm, the gasket strip can be installed conveniently, accurately, and efficiently. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The installation tool includes a positioning plate 19, and eight limiting blocks 20 are bolted to the positioning plate 19. The eight limiting blocks 20 enclose a rectangular positioning area for placing the laptop computer shell to be installed with the pad strip.

[0021] like Figure 1 As shown, the loading device includes a base 1, a vertical motor is fixed with bolts in the middle of the base 1, the motor output shaft is facing upward and is bolted to a circular support plate 4, a support frame 3 is provided between the base 1 and the support plate 4, the bottom of the support frame 3 is bolted to the base 1, an annular slide groove is welded on the top of the support frame 3, a number of ball bearings are distributed in the slide groove, an annular slide rail is bolted to the bottom of the support plate 4, and the slide rail is inserted into the slide groove and contacts the ball bearings.

[0022] Six fan-shaped loading plates 2 are distributed around the motor axis on the support plate 4. Several strip-shaped loading slots 5 are arranged side by side on the upper end of the loading plates 2. The loading slots 5 are radially distributed outward with the motor axis as the center. A plurality of sockets 7 corresponding to the pad mounting columns are distributed along the length direction at the bottom of the loading slots 5. A "high" and "low" identification mark (not shown in the figure) is provided on the loading plate 2 outside the end of each loading slot 5. The identification mark is located at the top of the outer arc side of the loading plate 2. The "high" and "low" identification marks are arranged at intervals. The identification marks are used to distinguish whether the loading slot 5 should be loaded with high pads or low pads. Wedge-shaped spacer blocks 10 are bolted to the support plate 4 between adjacent loading plates 2. The spacer blocks 10 are arranged radially along the support plate 4 and are located outside the large end of the loading plate 2. Two positioning grooves 6 are provided at the small end of the loading plate 2, and positioning columns corresponding to the positioning grooves 6 are threadedly connected to the support plate 4. A height limiting block 9 is fixed with bolts on the support plate 4 between two adjacent positioning columns, and the bottom surface of the height limiting block 9 can be in contact with the top surface of the loading plate 2.

[0023] The support plate 4 is provided with radial strip holes 8, and there are six strip holes 8 corresponding to the loading plate. The bottom of the support plate 4 is bolted with a U-shaped guide groove 13, and the guide groove 13 is arranged radially along the support plate 4. A push rod 12 is slidably connected in the guide groove 13. A through hole is provided in the middle of the loading plate, and a bolt is provided in the through hole to pass through the strip hole 8 and fix the push rod 12.

[0024] The push rod 12 extends to the outside of the support plate 4. A cylinder 11 that can be extended and retracted along the radial direction of the support plate 4 is bolted to the support frame 3. The retractable end of the cylinder 11 can push the end of the push rod 12.

[0025] The specific implementation process is as follows: During use of this embodiment, the laptop computer case to be installed with the pad strip is placed bottom-up on the positioning plate 19 of the installation fixture and accurately positioned using the stopper 20. The motor drives the support plate 4 to rotate, and the support frame 3 provides support and reinforcement for the support plate 4 through the slide groove, slide rails, and ball bearings, ensuring that the support plate 4 remains stable during rotation. After the worker manually grabs multiple pads, he pulls the push rod 12 to pull one loading plate 2 outward to distinguish it from the other loading plates 2, observes the identification mark on the loading plate 2 in front, places the corresponding high pads and short pads in the empty loading slot 5, and inserts the mounting column at the bottom of the pad into the socket 7. After the pads on one loading plate 2 are placed in batches, the worker manually pushes the push rod 12 or pushes the push rod 12 through the cylinder 11 to push the loading plate 2 back. During the pushing back process, the radial positioning of the loading plate 2 is achieved through the contact between the positioning groove 6 and the positioning column, the axial position of the loading plate 2 is limited by the height limit block 9, and the loading plate 2 is moved and guided by the spacer block 10 and the bolts in the long strip hole, thereby ensuring that the loading plate 2 is accurately positioned after it is reset. The worker's loading position is located opposite the robot's grasping position. During operation, the robot arm 14 moves the mounting base 16 to above the support plate 4. The reversing motor 15 adjusts the angle of the mounting base 16 so that one negative pressure suction cup 18 is parallel to a pad on the lower loading plate 2. The corresponding grasping cylinder 17 then lowers the negative pressure suction cup 18. The negative pressure absorbs and grabs the pad, and then the negative pressure suction cup 18 is reset. The robot arm 14 and reversing motor 15 rotate to move the other negative pressure suction cup 18. At the same time, the support plate 4 rotates a certain angle to align the negative pressure suction cup 18 with the other pad on the lower loading plate 2. The pad is then sucked and grabbed using the same operating principle. The high pads and low pads on the loading plate are placed at intervals, and the motor uses a stepper motor to move only the interval angle of one pad at a time, while the reversing motor 15 and the robotic arm 14 control the two negative pressure suction cups 18 to grab the pads at the same position, so that the two bar-shaped negative pressure suction cups 18 move separately, and only one of them grabs one pad at a time, grabbing a high pad and a low pad twice respectively, and then the robotic arm 14 rotates to move the two grabbed pads to the top of the installation tooling, so that the negative pressure suction cup 18 and the pad are aligned with the pad installation position on the laptop computer case below, and then the pads are pressed into place respectively through the grabbing cylinder 17, and then the negative pressure source is stopped so that the negative pressure suction cup 18 no longer adsorbs and grabs the pad, the grabbing cylinder 17 resets the negative pressure suction cup 18, and then the robotic arm 14 resets for the next grab. In this way, the equipment provided by the present invention adopts semi-automatic loading device, and different pads are placed in place accordingly through manual identification and guidance of identification marks. A number of pads can be loaded in batches for use, and then the support plate 4 and the loading plate 2 automatically move the pads continuously toward the robotic arm 14. The robotic arm 14 automatically grabs a high pad and a low pad through the negative pressure suction cup 18, and then transfers it to the installation station, and automatically presses the pad into place to complete the automated installation of the pad.The entire process only requires manual identification and placement of the pads. There is a certain reserve for loading, and the pad installation is automated. The labor intensity of workers is reduced, the accuracy of pad identification and placement is improved, the efficiency of the installation process is improved, and the overall production efficiency is significantly improved, which can effectively meet the needs of mass production.
