Description

Technical Field

[0001] This invention relates to the field of furniture manufacturing technology, and in particular to an assembly device and its method of use. Background Technology

[0002] Staff desk partitions are partitions installed on staff workstations. These partitions are commonly used in office environments to provide staff with a degree of privacy while also helping to distinguish different work areas.

[0003] One of the main components of the staff desk partition is the central pole. When assembling the central pole, employees need to manually assemble the parts and aluminum materials, then use a pneumatic screwdriver to tighten the screws, and finally assemble it with the entire partition.

[0004] The assembly process of the central pole of the screen requires: one horizontal bar corresponds to two end caps, and each end cap is equipped with four screws. Therefore, the assembly process of the staff desk screen suffers from low efficiency and complicated assembly steps. Summary of the Invention

[0005] The main objective of this invention is to provide an assembly device and its method of use, aiming to solve the problems of low assembly efficiency and complicated assembly steps in the current screen central rod assembly.

[0006] The objective of this invention can be achieved by adopting the following technical solution:

[0010] A profile positioning mechanism is used to support and limit the position of a profile.

[0011] The parts pressing mechanism includes: a parts feeding unit, a robotic arm unit, and a pressing unit;

[0012] The accessory feeding unit is used to transport multiple accessories to a predetermined position, so that the robotic arm unit can take out at least one accessory from the predetermined position and transfer the accessory to the end of the profile along a first specified path. The pressing unit is configured to press the accessory to the end along a second specified path.

[0013] A tightening mechanism, comprising: a fastener feeding unit, a tightening unit, and a guiding mechanism;

[0014] The fastener feeding unit is configured to feed fasteners to the tightening unit, which is located on the guide mechanism. The guide mechanism is used to drive the tightening unit to move closer to or away from different parts of the end, so as to screw the fasteners on the tightening unit into the end and the accessories thereon.

[0015] A distance adjustment mechanism is also provided between the two assembly mechanisms.

[0016] The profile positioning mechanism includes a positioning groove group and a cylinder assembly. The positioning groove group is used to provide lateral support for the profile, so that the cylinder assembly can press the profile.

[0017] The positioning groove group is detachable and includes multiple positioning grooves of different widths.

[0018] The robotic arm unit includes a first linear drive mechanism and a robotic arm mounted on the first linear drive mechanism.

[0019] The accessory feeding unit includes a vibration assembly and a disc disposed on top of the vibration assembly, the disc having a groove.

[0020] The channel is located below the robotic arm and is parallel to the first linear drive mechanism.

[0021] The pressing unit includes a second linear drive mechanism and a third linear drive mechanism, wherein the third linear drive mechanism is provided with a pressing member;

[0022] The second linear drive mechanism is vertically arranged and is used to drive the third linear drive mechanism to move up and down;

[0023] After the third linear drive mechanism moves upward, the pressing member aligns with the accessory so that the third linear drive mechanism can drive the pressing member to press the accessory to the end.

[0024] The guiding mechanism includes a fourth linear drive mechanism and a fifth linear drive mechanism that are perpendicular to each other. The tightening unit is disposed on the fourth linear drive mechanism or the fifth linear drive mechanism so that the tightening unit can move in the lateral and longitudinal directions.

[0025] A method of using an assembly apparatus, the method being performed by the assembly apparatus described above, the method comprising the following steps:

[0026] Step 1: Place the middle rod horizontally between the two assembly mechanisms;

[0027] Step 2: Use the profile positioning mechanism in the two assembly mechanisms to support and limit the two ends of the middle rod;

[0028] Step 3: Place multiple loose plugs on the accessory feeding unit, allowing it to orient and transport the multiple plugs to the predetermined position;

[0029] Step 4: After the robotic arm unit removes a plug from the predetermined position, it transfers the plug to the end of the central rod along the first designated path.

[0030] Step 5: The pressing unit presses the plug to the end along the second designated path;

[0031] Step 6: The fastener feeding unit delivers the screws to the tightening unit;

[0032] Step 7: The guide mechanism drives the tightening unit to move closer to or further away from the end at different positions.

[0033] The step of the guide mechanism driving the tightening unit to move closer to or further away from the end at different positions further includes:

[0034] Step 7.1: The guide mechanism drives the tightening unit closer to the end, and the screw is tightened into the end while rotating;

[0035] Step 7.2: The guide mechanism drives the tightening unit away from the end and adjusts the position of the tightening unit so that the new screw is aligned with the new position of the end;

[0036] Step 7.3: Repeat steps 7.1 and 7.2 until multiple screws are screwed into the end of the middle rod to complete the assembly between the middle rod and the plug.

[0037] Beneficial technical effects of the present invention:

[0038] The assembly device provided by this invention includes a profile positioning mechanism, a component pressing mechanism, and a tightening mechanism. It can automatically assemble the center rod and the end cap, significantly improving assembly speed and reducing the time required for manual assembly, effectively solving the problem of low efficiency in traditional manual assembly. It also reduces the need for manual operation, thereby reducing errors and product quality fluctuations caused by improper human operation, and saving labor costs.

[0039] This invention effectively shortens the installation time of the center rod in each independent process by integrating multiple processes such as profile positioning, component pressing, and tightening into a single assembly device. This integrated automated assembly method combines multiple previously scattered processes into a continuous automated flow, reducing transfer and waiting time between processes. This integrated automated assembly method reduces transfer time and complexity between processes, making the entire assembly process smoother and more efficient. Attached Figure Description

Detailed Implementation

[0052] To enable those skilled in the art to understand the technical solution of the present invention more clearly, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0053] like Figures 1-9 As shown, the assembly apparatus provided in this embodiment includes:

[0054] Frame 1 primarily provides stable support and a layout platform for other components of the assembly unit. Frame 1 houses two opposing assembly mechanisms. During the assembly of profiles and accessories, the profiles are placed laterally between the two assembly mechanisms. Here, the profile is the screen's central pole, and the accessory is the end cap.

[0055] Each assembly mechanism includes: profile positioning mechanism 2, accessory pressing mechanism 3, and tightening mechanism 4.

[0056] Among them, the profile positioning mechanism 2 is used to support and limit the center rod, ensuring that the center rod will not shift during subsequent assembly, thereby ensuring that the plug can be accurately pressed into the corresponding end of the center rod.

[0057] Each end of the central rod is supported and limited by a profile positioning mechanism 2 of an assembly mechanism, achieving independent positioning at both ends.

[0058] The parts pressing mechanism 3 includes: parts feeding unit 301, robotic arm unit 302 and pressing unit 303.

[0059] The parts loading unit 301 orients and transports multiple loose plugs to a predetermined position. The predetermined position is a specific location on the parts loading unit 301.

[0060] The robotic arm unit 302 removes a plug from a predetermined position and moves it along a first designated path to the corresponding end position of the central rod that is limited by the profile positioning mechanism 2.

[0061] like Figure 2 As shown, after the plug is located at the corresponding end position of the middle rod, the pressing unit 303 presses the plug onto the end along the second specified path.

[0062] The second specified path here is a linear path.

[0063] Movement along a linear path allows the pressing unit 303 to apply force evenly to the plug, which helps ensure that the plug is pressed into the corresponding end evenly and stably, reducing the problem of incorrect plug installation caused by uneven force application.

[0064] The tightening mechanism 4 includes: a fastener feeding unit 401, a tightening unit 402, and a guiding mechanism 403.

[0065] The fastener feeding unit 401 and the tightening unit 402 are arranged adjacent to each other, and the fasteners can be fed to the tightening unit 402. The fasteners are self-tapping screws.

[0066] The tightening unit 402 is mounted on the guide mechanism 403, which can drive the tightening unit 402 to approach or move away from different parts of the end of the center rod.

[0067] As it approaches, the screws on the tightening unit 402 are screwed into the end of the center rod while rotating.

[0068] When moving away, the guide mechanism 403 adjusts the position of the tightening unit 402 so that the screw on it is aligned with the end of the center rod. The alignment point here is different from the point where the screw was previously screwed in. After alignment, the screw is screwed into the end of the center rod.

[0069] Continue in this manner until four screws are screwed into each end of the middle rod, thus completing the assembly between the end of the middle rod and its upper plug.

[0070] In this embodiment, both the fastener feeding unit 401 and the tightening unit 402 are mounted on the guide mechanism 403. This allows the fastener feeding unit 401 and the tightening unit 402 to move synchronously, so that the fastener feeding unit 401 can continuously and stably feed the fasteners to the tightening unit 402.

[0071] In this embodiment, the guide mechanism 403 provides linear drive in two directions to allow the tightening unit 402 to approach or move away from different locations where the plug and the corresponding end of the center rod meet.

[0072] The linear drives in the two directions mentioned above are lateral drive and longitudinal drive, respectively, which are left-right movement and forward-backward movement.

[0073] When the tightening unit 402 moves left or right, it moves closer to or further away from the aforementioned joint.

[0074] When the tightening unit 402 moves back and forth, it can be combined with left and right movements to screw the screws into different positions at the end of the middle rod, so that multiple screws can be screwed into the end of the middle rod and the plug on it respectively.

[0075] In this embodiment, the first designated path is the first linear path.

[0076] In other words, after the robotic arm unit 302 removes the plug, the movement path of the plug is linear. This ensures that its horizontal movement direction remains constant during the process of the plug being removed and transferred to the corresponding end of the central rod.

[0077] In this way, the process of transferring the plug to the end of the middle rod can be carried out in a single dimension, which greatly reduces the variables and potential errors in the movement of the plug.

[0078] The result is higher positioning accuracy and repeatability, which is crucial for the correct alignment and press-fitting of the plug to the end of the center rod.

[0079] In this embodiment, the second designated path specifically consists of two mutually perpendicular linear paths: a second linear path and a third linear path.

[0080] The second linear path is a vertical straight path, while the third linear path is a horizontal straight path.

[0081] This design ensures that each movement of the press-fit unit 303 is limited to a single dimension, rather than involving compound movements in multiple dimensions simultaneously. This significantly improves the alignment accuracy between the plug and the end of the center rod, ensuring that each press-fit is completed accurately.

[0082] When moving along the second linear path, the main purpose is to enable the pressing unit 303 to align the plug in the horizontal direction; when moving along the third linear path, the pressing unit 303 presses the plug into the corresponding end of the middle rod.

[0083] In this embodiment, the complexity of the control system is greatly reduced when motion is restricted to a single dimension. This not only simplifies the design and manufacture of the robotic arm unit 302 and the pressing unit 303, but also makes their operation and maintenance easier.

[0084] In this embodiment, a linear path is chosen for the transport and positioning of the plugs to improve the accuracy and efficiency of assembly, while reducing the complexity and maintenance requirements of the control system of the robotic arm unit 302. This is crucial for achieving high-quality and high-efficiency automated assembly of the screen center rod.

[0085] In this embodiment, a distance adjustment mechanism is also provided between the two assembly mechanisms to allow the assembly device to adapt to center rods of different lengths. That is, the assembly device can perform assembly processes on screen center rods of different lengths.

[0086] In this embodiment, as Figure 1 As shown, the two assembly mechanisms are distributed on the left and right sides, with the assembly mechanism on the left being called the first assembly mechanism 101 and the assembly mechanism on the right being called the second assembly mechanism 102.

[0087] The distance adjustment mechanism includes a ball screw 5, which is disposed between the second assembly mechanism 102 and the frame 1. The distance between the first assembly mechanism 101 and the second assembly mechanism 102 is adjustable via the ball screw 5.

[0088] In this embodiment, as Figure 1 As shown, the second assembly mechanism 102 is provided with a support plate 6 at the bottom, the nut seat 501 of the ball screw 5 is connected to the bottom surface of the support plate 6, and the screw 502 of the ball screw 5 is placed horizontally on the inner side of the frame 1.

[0089] The ball screw 5 can move the second assembly mechanism 102 away from or closer to the first assembly mechanism 101 by moving the support plate 6, thereby realizing the distance adjustment between the first assembly mechanism 101 and the second assembly mechanism 102.

[0090] In this embodiment, the profile positioning mechanism 2 includes a positioning groove group 201 and a cylinder assembly 202.

[0091] The positioning groove assembly 201 includes multiple positioning grooves 2012 of different widths to accommodate center rods of different widths.

[0092] The center rod can be placed horizontally in the positioning groove 2012. At this time, the cylinder assembly 202 near the positioning groove group 201 can press the center rod in the positioning groove 2012 to make it stable.

[0093] This ensures that the center rod will not shift or lift when the plug is pressed into the end of the center rod, thus guaranteeing that the plug can be correctly aligned and pressed into the end of the center rod.

[0094] In this embodiment, the positioning slot group 2011 further includes a positioning stage 2011.

[0095] Multiple positioning slots 2012 are spaced apart on the top surface of the positioning platform 2011, and their distribution direction is the same as the length direction of the positioning platform 2011, so as to place multiple center rods of different widths on the positioning platform 2011.

[0096] The length direction of the positioning groove 2012 is the same as the width direction of the positioning platform 2011, ensuring that the central rod can be placed horizontally on the positioning groove 2012 of the positioning platform 2011.

[0097] In this embodiment, the assembly device further includes a support frame 7, and a positioning platform 2011 is detachably disposed on the top surface of the support frame 7 to realize the modular replacement of the positioning slot group 2011.

[0098] The support frame 7 provides a certain height for the positioning platform 2011, so that after it supports the center rod, the robotic arm unit 302 can directly reach the corresponding end position of the center rod after retrieving the plug along the first designated path, without needing to add an additional movement path for the robotic arm unit 302. The first designated path is a straight path.

[0099] In this embodiment, threaded holes are provided on the bottom surface of the positioning platform 2011 and the top surface of the support frame 7. The threaded holes can be connected together by a screw, thereby enabling the positioning platform 2011 to be installed in a detachable manner.

[0100] In this embodiment, the cylinder assembly 202 includes a first cylinder 2021 and a fixing plate 2022, with the first cylinder 2021 disposed inside the support frame 7.

[0101] The piston rod 20211 of the first cylinder 2021 passes through the top surface of the support frame 7 from bottom to top, and the fixing plate 2022 is installed on the top of the piston rod 20211. In this configuration, the fixing plate 2022 is located directly above the positioning platform 2011.

[0102] Once the middle rod is positioned on the positioning platform 2011, the first cylinder 2021 is activated, causing the piston rod 20211 to move the fixing plate 2022 downwards until the fixing plate 2022 presses tightly against the middle rod on the positioning platform 2011.

[0103] Through this process, the center rod is firmly fixed in place, ensuring that it will not shift or tilt during subsequent assembly operations.

[0104] In this embodiment, the robotic arm unit 302 includes: a first linear drive mechanism 3021 and a robotic arm 3022 disposed on the first linear drive mechanism 3021.

[0105] The first linear drive mechanism 3021 is located above the positioning stage 2011 and is parallel to the positioning stage 2011.

[0106] This parallel arrangement allows the robot arm 3022 to move along a direct and efficient straight path when delivering the plug. Because it moves along a path parallel to the positioning table 2011, the robot arm 3022 is able to more accurately align and place the plug at the end of the center rod.

[0107] After the robot arm 3022 removes the plug from the predetermined position, it is guided by the first linear drive mechanism 3021 to move along the positioning stage 2011 until the robot arm 3022 accurately places the plug at the end of the middle rod.

[0108] The linear drive mechanism 3021 provides a simplified linear path, allowing the end cap to move to the center rod end in a linear motion. Linear motion is faster than complex multidimensional motion because it is direct and does not require passing through multiple coordinate points. This improves the speed and efficiency of the entire assembly process.

[0109] In this embodiment, the robotic arm 3022 includes a second cylinder 30221 and a pneumatic gripper 30222 disposed at the bottom of the second cylinder 30221.

[0110] The second cylinder 30221 is vertically arranged relative to the first linear drive mechanism 3021, and the second cylinder 30221 is located between the pneumatic gripper 30222 and the first linear drive mechanism 3021.

[0111] The vertical orientation of the second cylinder 30221 allows the robot arm 3022 to be adjusted in height in the vertical direction. This design enables the pneumatic gripper 30222 to move up and down according to different height requirements in order to accurately grip the plug at a predetermined position.

[0112] Because the second cylinder 30221 can adjust the position of the pneumatic gripper 30222, the flexibility and adaptability of the robot arm 3022 are enhanced. This means that the robot arm 3022 can adapt to different heights, even if there are slight changes or deviations in the placement of the plug.

[0113] In this embodiment, the accessory feeding unit 301 is a vibratory feeder, which includes a vibration component 3011 and a disc 3012 disposed on the top of the vibration component 3011. The disc 3012 is provided with a channel 3013.

[0114] The channel 3013 is located below the pneumatic gripper 30222 and is parallel to the first linear drive mechanism 3021, so that the pneumatic gripper 30222 can directly remove the plug from the channel 3013.

[0115] Multiple plugs are placed into the disc 3012, and the vibration component 3011 vibrates. The vibration causes the plugs on the disc 3012 to move and arrange along a predetermined path. The plugs on the disc 3012 will eventually move into the channel 3013 in sequence.

[0116] The channel 3013 provides the aforementioned predetermined position, specifically at the tail of the channel 3013, so that after the pneumatic gripper 30222 removes the plug, it can move directly along the direction of the positioning table 2011 and move the gripped plug to the corresponding end position of the middle rod on the positioning table 2011.

[0117] In this embodiment, the accessory feeding unit 301 provides the plug to a position accessible to the pneumatic gripper 30222, reducing the complexity of operation and making the entire feeding process more efficient and reliable.

[0118] The design of the accessory loading unit 301 is closely coordinated with the layout of the pneumatic gripper 30222 and the first linear drive mechanism 3021, ensuring the smoothness and efficiency of the entire assembly process.

[0119] In this embodiment, since the channel 3013 is parallel to the first linear drive mechanism 3021, the pneumatic gripper 30222 can directly remove the plug from the channel along a straight path. This linear motion is more efficient than complex, multi-axis motion because it reduces the number of movements required and the complexity of mechanical components.

[0120] In this embodiment, the pressing unit 303 is located below the positioning platform 2011, and the middle rod and the end cap are located above the pressing unit 303.

[0121] The pressing unit 303 includes: a second linear drive mechanism 3031, a third linear drive mechanism 3032 on the second linear drive mechanism 3031, and a pressing member 3033 on the third linear drive mechanism 3032.

[0122] The second linear drive mechanism 3031 is vertically arranged and is responsible for the vertical movement of the third linear drive mechanism 3032, that is, for the vertical movement of the pressing member 3033.

[0123] The second linear drive mechanism 3031 can control the up and down position of the pressing member 3033 to ensure that the pressing member 3033 is aligned with the plug to be installed.

[0124] The third linear drive mechanism 3032 is horizontally positioned and is responsible for moving the pressing member 3033 in the horizontal direction.

[0125] Before the pressing process begins, the second linear drive mechanism 3031 moves the third linear drive mechanism 3032 to an appropriate height so that the pressing member 3033 is aligned with the center rod and the plug on it.

[0126] Once the vertical position is secured, the third linear drive mechanism 3032 drives the pressing member 3033 to approach the plug in the horizontal direction until the plug is pressed into the corresponding end of the central rod.

[0127] After the operation is completed, the pressing part 3033 returns to its initial position to facilitate subsequent processes.

[0128] In this embodiment, by combining vertical and horizontal linear drive, the pressing member 3033 can more accurately align the plug and the end of the middle rod.

[0129] Vertical drive ensures that the pressing component 3033 starts pressing from the correct height, while horizontal drive ensures precise approach along a straight line.

[0130] Since each drive mechanism of the press unit 303 is only responsible for movement in one direction, the complexity of the movement is reduced, thereby reducing the possibility of operational errors and improving the accuracy of overall assembly.

[0131] The separate linear drive allows for faster operating speeds and smoother movement. After vertical alignment, horizontal movement can be performed quickly and smoothly, reducing the overall pressing process time.

[0132] The coordinated operation of the second and third linear drive mechanisms of the press unit 303 not only improves the accuracy and efficiency of the assembly process, but also makes the entire assembly process more stable and reliable, and reduces maintenance costs.

[0133] In this embodiment, the fastener feeding unit 401 and the tightening unit 402 are connected by a transparent plastic tube 404. The fastener feeding unit 401 is a blow-type screwdriver, and the tightening unit 402 is an electric pneumatic screwdriver.

[0134] Fastener feeding unit 401 feeds ST4*16 into the front end of tightening unit 402 through a transparent plastic tube.

[0135] In this embodiment, the guide mechanism 403 includes a fourth linear drive mechanism 4031 and a fifth linear drive mechanism 4032. The fourth linear drive mechanism 4031 is disposed on top of the fifth linear drive mechanism 4032, and the two are arranged perpendicular to each other.

[0136] The fourth linear drive mechanism 4031 provides lateral linear drive, and the fifth linear drive mechanism 4032 provides longitudinal linear drive.

[0137] Both the fastener feeding unit 401 and the tightening unit 402 are mounted on the fourth linear drive mechanism 4031 to facilitate bidirectional linear drive of the tightening unit 402.

[0138] like Figure 10 As shown, this embodiment also provides a method for using the assembly device, which is performed by the assembly device described above. The method includes the following steps:

[0139] Step 1: Place the center rod horizontally between the two assembly mechanisms to facilitate simultaneous operation on both ends of the center rod, thereby improving the assembly efficiency of the center rod and the plug.

[0140] Step 2: Use the profile positioning mechanism 2 in the two assembly mechanisms to support and limit the two ends of the middle rod to ensure that the position of the middle rod does not shift during the assembly process;

[0141] Step 3: Place multiple loose plugs on the parts feeding unit 301, allowing it to orient and transport the plugs to the predetermined position. The automated feeding process reduces manual intervention and improves the continuity and efficiency of assembly.

[0142] Step 4: After the robotic arm unit 302 takes out a plug from the predetermined position, it transfers the plug to the end of the central rod along the first designated path to ensure the accurate transmission and positioning of the plug and reduce assembly errors.

[0143] Step 5: Pressing unit 303 presses the plug evenly into the end along the second specified path. The uniform pressure distribution ensures that there is no relative tilt between the two after the plug is pressed into the corresponding end.

[0144] Step 6: Fastener feeding unit 401 feeds the screws to tightening unit 402;

[0145] Step 7: The guide mechanism 403 drives the tightening unit 402 to approach or move away from the end at different positions.

[0146] In this embodiment, the step of the guide mechanism 403 driving the tightening unit 402 to approach or move away from the end at different positions further includes:

[0147] Step 7.1: The guide mechanism 403 drives the tightening unit 402 to approach the end, and the screw is tightened into the end while rotating;

[0148] Step 7.2: The guide mechanism 403 drives the tightening unit 402 away from the end and adjusts the position of the tightening unit 402 so that the new screw is aligned with the new position of the end.

[0149] Step 7.3: Repeat steps 7.1 and 7.2 until multiple screws are screwed into both ends of the center rod to complete the assembly between the center rod and the plug.

[0150] In summary, in this embodiment, the profile positioning mechanism 2 provides accurate support and positioning for the center rod. This precise positioning greatly reduces the time spent adjusting and confirming the center rod position in traditional manual operations, allowing the center rod to be assembled in place in one go without repeated adjustments.

[0151] The accessory loading unit 301 provided in this embodiment automatically orients and transports the scattered plugs, while the robotic arm unit 302 quickly and accurately removes the plugs and transfers them to the end of the central rod. This automated process not only improves the speed of plug assembly but also reduces errors and repetitive adjustment time in manual operation.

[0152] The automated operation of the tightening mechanism 4 provided in this embodiment, especially the synchronous movement function of the fastener feeding unit and the tightening unit, improves the efficiency of screw tightening. The automated bidirectional linear drive and precise control ensure that the screw is tightened into the plug and the end of the rod quickly and accurately. This not only shortens the screw tightening time but also reduces the need for readjustment or repetition due to inaccurate manual operation.

[0153] The assembly device provided in this embodiment integrates the three main processes of profile positioning, accessory pressing, and tightening into a continuous automated process. This continuity means that the transfer of aluminum materials from one process to the next requires almost no waiting time, greatly reducing the interruptions and delays commonly found in independent processes.

[0154] At the same time, since each process is performed by precisely controlled automated equipment, the possibility of human error is reduced. This means less time for rework or adjustment due to errors, further improving overall assembly efficiency.
