Description

Technical Field

[0001] This utility model relates to the field of workpiece production and processing technology, and in particular to a transfer and flipping device. Background Technology

[0002] In modern production lines, workpieces undergo multiple processing steps, often requiring switching of the processed surfaces, which often necessitates flipping the workpiece. Take the back panel of a television set as an example: in the previous station, the processed surface of the back panel is the front. In the next station, wall-mounted rivets need to be riveted to the front of the back panel. Due to the structure of the wall-mounted rivets, riveting requires the processed surface of the back panel to be the back. This means the back panel needs to be flipped 180° so that the front is facing down and the back is facing up. The wall-mounted rivets are then inserted from the back of the back panel, and a stamping mechanism presses them downwards, forcing them into the back panel, thus achieving the riveting of the wall-mounted rivets to the back panel. This necessitates a flipping mechanism between the two stations.

[0003] Chinese utility model patent CN208409325U discloses a rapid workpiece flipping and transfer mechanism, including a production line fixture, pneumatic grippers, a rotary cylinder, and an XZ-axis displacement assembly. The production line fixture consists of a fixture plate, a first fixture, and a second fixture, which are fixed side-by-side on the fixture plate. The first fixture is used for front-side clamping and positioning of the workpiece, and the second fixture is used for back-side clamping and positioning of the workpiece. The pneumatic grippers are mounted on the turntable of the rotary cylinder. The rotary cylinder is mounted on the Z-axis slide of the XZ-axis displacement assembly. This patent enables workpiece flipping, lifting, and transfer.

[0004] When the aforementioned flipping and loading mechanism is applied between two workstations on a TV back panel production line, it resembles a straight production line. Since the process of flipping the workpiece and placing the rivets is the most time-consuming, the aforementioned patent requires waiting for the workpiece to be flipped and for the worker to place the rivets before loading and unloading can proceed. This results in low production efficiency. Furthermore, in a straight production line, workers are too close to the mechanical moving devices (such as robotic arms), posing a safety hazard. Utility Model Content

[0005] To address the technical problems of low production efficiency and safety hazards in existing technologies, this utility model provides a transfer-type flipping device.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A transfer-type flipping device is provided, including a base, on which a first conveying route extending in a left-right direction is provided. The first conveying route is provided with a first station, a second station and a third station from left to right. It also includes a workpiece clamping mechanism that can move along the first conveying route for transferring workpieces between the first station, the second station and the third station.

[0008] The base is provided with a second conveyor route that extends forward through the second workstation. A fourth workstation is provided on the second conveyor route. A flipping mechanism for flipping the workpiece at the fourth workstation is provided on the fourth workstation.

[0009] The second conveyor route is equipped with a first workbench and a second workbench. The second conveyor route is also equipped with a first slide rail and a second slide rail arranged in a front-to-back direction. The first slide rail is located above the second slide rail. One of the first workbench and the second workbench is installed on the first slide rail, and the other is installed on the second slide rail. A drive mechanism is provided on the base. The drive mechanism drives the first workbench and the second workbench to move synchronously and in opposite directions. When the first workbench moves from the second station to the fourth station, the second workbench moves from the fourth station to the second station; when the first workbench moves from the fourth station to the second station, the second workbench moves from the second station to the fourth station.

[0010] Furthermore, the second worktable is mounted on the first slide rail, the first worktable is mounted on the second slide rail, the drive mechanism drives the first worktable to reciprocate on the second slide rail, and the drive mechanism drives the second worktable to reciprocate on the first slide rail.

[0011] Furthermore, the drive mechanism includes a rotating wheel, a ring transmission component, and a first motor capable of forward and reverse rotation. The rotating wheel is located on the front and rear sides of the base and is connected to the output shaft of the motor. The rotation axis of the rotating wheel is arranged horizontally in the left-right direction. The ring transmission component is wound around the rotating wheel on both the front and rear sides. The length direction of the ring transmission component is parallel to the front-back direction. The ring transmission component includes an upward advancing part and a downward advancing part with opposite directions of travel. The upward advancing part is fixedly connected to the second worktable, and the downward advancing part is fixedly connected to the first worktable.

[0012] Furthermore, the rotating wheel is a gear, the annular transmission component is a synchronous belt, the inner side of the synchronous belt has trapezoidal teeth that mesh with the gear, both the first and second worktables extend with connecting parts, the connecting parts contact the outer side of the synchronous belt, and also include a connecting plate, the surface of the connecting plate facing the inner side of the synchronous belt has trapezoidal teeth, the trapezoidal teeth of the connecting plate cooperate with the trapezoidal teeth on the inner side of the synchronous belt, the connecting part is provided with a first connecting hole, the connecting plate is provided with a corresponding second connecting hole, the first connecting hole and the second connecting hole are aligned and bolts are passed through, so that the connecting part and the connecting plate clamp the synchronous belt.

[0013] Furthermore, the first workbench and the second workbench are equipped with a lifting platform on the second slide rail, and the other is a translational platform. The lifting platform includes a base and a lifting platform, and a telescopic mechanism is provided between the base and the lifting platform. The base is installed on the second slide rail, and the translational platform is installed on the first slide rail. When the telescopic mechanism is fully retracted, the lifting platform is located below the translational platform. The drive mechanism drives the base and the translational platform to move synchronously and in opposite directions.

[0014] Furthermore, when the telescopic mechanism is fully extended, the upper surface of the lifting platform and the upper surface of the translation platform are at the same height.

[0015] Furthermore, both the first and second slides are arranged horizontally along the front-to-back direction.

[0016] Furthermore, it also includes a lifting mechanism driven by a linear motor and a controller for controlling the start and stop of the lifting mechanism. The lifting mechanism includes a slider and a vertically arranged slide rail. The slider can move up and down along the slide rail. The flipping mechanism includes a clamping member and a second motor. The output shaft of the second motor is horizontally arranged in the left and right direction. The clamping member is connected to the output shaft of the second motor. The second motor is fixed on the slider.

[0017] Furthermore, the workpiece clamping mechanism includes a vacuum generator, pipelines, a support, and four vacuum chucks. The four vacuum chucks are mounted on the support and arranged in a rectangular shape at the four corners. The vacuum generator is connected to the vacuum chucks through pipelines.

[0018] Furthermore, both the first and second worktables are equipped with positioning mechanisms. The positioning mechanisms include vertically arranged support columns and limiting blocks. The support columns are located on the lower surface of the workpiece and are used to support the lower surface of the workpiece. The limiting blocks are distributed in a ring around the perimeter of the workpiece and are used to restrict the workpiece from moving to the surrounding areas.

[0019] The beneficial effects of this utility model are:

[0020] This invention enables multiple processes to run in parallel, significantly improving production efficiency. By moving the most time-consuming workpiece flipping and riveting processes from the second station on the main production line to an independent fourth station, and utilizing a layered design of the second conveyor route (including the first and second slides) and its opposing double worktables (the first and second worktables), the critical processes and other steps are executed synchronously and in parallel. Specifically:

[0021] When the device is performing loading (from the first station to the second station) or unloading (from the second station to the third station) operations on the main production line, the fourth station can simultaneously perform workpiece flipping and riveting operations. At the same time, with the help of the reverse-moving double worktables (the first worktable and the second worktable), the workpieces that have been flipped and riveted are quickly sent back to the second station from the fourth station, while newly loaded workpieces awaiting processing are quickly sent from the second station to the fourth station.

[0022] This completely avoids the "waiting" time inherent in traditional linear production lines, where loading and unloading can only proceed after the flipping and rivet loading are complete. This significantly shortens the overall production cycle time and dramatically improves production efficiency. The fourth station is independently located away from areas of frequent mechanical movement on the main production line (especially near the second station). This provides operators with a relatively independent and less disruptive space to safely perform rivet loading operations at the fourth station, effectively reducing safety hazards.

[0023] In addition, the flipping process was separated from the main "one-line" production line, and a dedicated second conveyor route and fourth workstation were set up, which optimized the production layout and process flow, enabling different processes to work together efficiently.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the present invention will be further described below with reference to the accompanying drawings.

[0031] First, it should be stated that the technical solutions of the embodiments of this application are clearly and completely described. The described embodiments are only some of the embodiments of this application, and not a limitation of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] In the description of this utility model, it should be understood that the terms "first", "second", "upper", "lower", "left", "right", "inner", "outer", "axial" or "radial" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and are not intended to indicate or imply that the device or element referred to must have a specific orientation structure and operation. Therefore, they should not be construed as limitations on this utility model.

[0033] Reference Figures 1 to 5 This utility model provides a transfer-type flipping device.

[0034] To address the issue that traditional linear production lines require the entire line to stop and wait when workpieces are flipped at the second station (3), this invention provides a transfer-type flipping device that parallelizes processes and eliminates waiting time. Specifically:

[0035] Main production line operation: When the workpiece clamping mechanism loads the workpiece from the first station 2 to the second station 3, and unloads the workpiece from the second station 3 to the third station 4;

[0036] Synchronous action: The fourth station 5 independently performs workpiece flipping and rivet loading (or other operations), so that the most time-consuming flipping and loading processes no longer block the main production line, shortening the overall cycle time.

[0037] like Figures 1 to 5 As shown, its specific embodiment is as follows: a transfer-type flipping device is provided, including a base 1, on which a first conveying route extending in the left and right direction is provided. The first conveying route is provided with a first station 2, a second station 3 and a third station 4 from left to right. It also includes a workpiece clamping mechanism that can move along the first conveying route for transferring workpieces between the first station 2, the second station 3 and the third station 4.

[0038] The base 1 is provided with a second conveying route that extends forward through the second station 3. The second conveying route is provided with a fourth station 5. The fourth station 5 is provided with a flipping mechanism for flipping the workpiece on the fourth station 5.

[0039] The second conveyor route is provided with a first workbench 6 and a second workbench 7. The second conveyor route is provided with a first slide rail 8 and a second slide rail 9 arranged in a front-back direction. The first slide rail 8 is located above the second slide rail 9. One of the first workbench 6 and the second workbench 7 is installed on the first slide rail 8, and the other is installed on the second slide rail 9. A drive mechanism is provided on the base 1. The drive mechanism drives the first workbench 6 and the second workbench 7 to move synchronously and in opposite directions. When the first workbench 6 moves from the second station 3 to the fourth station 5, the second workbench 7 moves from the fourth station 5 to the second station 3; when the first workbench 6 moves from the fourth station 5 to the second station 3, the second workbench 7 moves from the second station 3 to the fourth station 5.

[0040] like Figures 1 to 5 As shown, for the workpiece clamping mechanism, a commercially available mechanical clamping mechanism can be used to clamp the workpiece; alternatively, a vacuum adsorption mechanism can be selected, including a vacuum generator (not shown), pipelines (not shown), a support 21, and four vacuum suction cups 22. The four vacuum suction cups 22 are mounted on the support 21 and arranged in a rectangular quadrant. The vacuum generator is connected to the vacuum suction cups 22 through pipelines. By using the vacuum generator to create a vacuum, the vacuum suction cups 22 adsorb the workpiece, thus reducing clamping marks on the workpiece surface and ensuring the workpiece's appearance quality. Regarding how the workpiece clamping mechanism moves the workpiece between the first station 2, the second station 3, and the third station 4, a linear motor-driven guide rail mechanism can be used. The workpiece clamping mechanism is mounted on the guide rail mechanism, allowing it to move in the left and right directions. A linear motor-driven guide rail mechanism can also be set up in the vertical direction, allowing the workpiece clamping mechanism to move vertically. Alternatively, a commercially available robotic arm can be used, capable of moving up and down, left and right, and forward and backward, allowing the workpiece to switch positions between the first station 2, the second station 3, and the third station 4.

[0041] like Figures 1 to 5As shown, for the flipping mechanism, commercially known mechanisms can be selected, such as rotary motors and grippers. The grippers hold the workpiece and flip it under the rotation control of the rotary motor, for example, flipping it 180°. Of course, to avoid motion interference during the flipping process, the flipping mechanism is raised to a certain height before flipping. For example, it also includes a linear motor driven lifting mechanism 18 and a controller for controlling the start and stop of the lifting mechanism 18. The controller is used to control the start and stop of the linear motor. It adopts existing technology known in the market and does not include any improvements to the computer program. The lifting mechanism 18 includes a slider 181 and a vertically arranged slide rail 182. The slider 181 can move up and down along the slide rail 182. The flipping mechanism includes a clamping member 19 and a second motor 20. The output shaft of the second motor 20 is horizontally arranged in the left and right direction. The clamping member 19 is connected to the output shaft of the second motor 20. The second motor 20 is fixed on the slider 181. The second motor 20 can be directly or indirectly fixed on the slider 181. For example, a linear motor driven guide rail mechanism is also provided between the two in the left and right direction. The second motor 20 is slidably mounted on the guide rail mechanism. The second motor 20 can move left and right. For fixing, it can be fixed by welding or bolting. Driven by the lifting mechanism 18, the slider 181 slides upward a certain distance. The second motor 20 is fixed to the slider 181. The clamping member 19 is connected to the output shaft of the second motor 20. This connection can be fixed, such as by welding or bolting, or it can be a transmission connection, such as by gear meshing. This allows the clamping member 19 to clamp the workpiece and move it upward a certain distance. After the output shaft of the second motor 20 rotates 180°, the workpiece is flipped. The slider 181 then moves downward, placing the workpiece on the worktable. The clamping member 19 then releases the workpiece, completing the flip. Clearly, this motion mechanism design requires a controller and utilizes commercially available technology, without any improvements to the computer program. For the clamping member 19, an electric gripper is preferred, but a manually or mechanically controlled gripper, or other commercially available clamping members 19, are also acceptable.

[0042] The first slide rail 8 and the second slide rail 9 can be arranged horizontally in the front-back direction or inclined at a small angle in the front-back direction, such as 5°, 8°, 9° or 10°, etc. There is no special limitation here, as long as the workpiece can be switched between the second station 3 and the fourth station 5, and the workpiece clamping mechanism can clamp the workpiece that has been rotated 180° (for example, the robotic arm can be adjusted according to the position of the workpiece).

[0043] One of the first worktable 6 and the second worktable 7 is installed on the first slide rail 8, and the other is installed on the second slide rail 9. In one embodiment, the second worktable 7 is installed on the first slide rail 8, and the first worktable 6 is installed on the second slide rail 9. The drive mechanism drives the first worktable 6 to reciprocate on the second slide rail 9, and the drive mechanism drives the second worktable 7 to reciprocate on the first slide rail 8.

[0044] like Figures 1 to 5 As shown, the first slide rail 8 and the second slide rail 9 can be sliding tracks, chutes, or supporting planes. They serve two purposes: supporting the first worktable 6 and the second worktable 7, and guiding their movement. The first slide rail 8 and the second slide rail 9 can be horizontally arranged sliding tracks along the front-to-back direction. Sliding blocks are correspondingly installed on the first worktable 6 and the second worktable 7. The drive mechanism can be a linear motor, causing the first worktable 6 and the second worktable 7 to move synchronously on the sliding track in opposite directions. It is important to note that the first worktable 6 and the second worktable 7 move in opposite directions to stagger their movements. Alternatively, they can be horizontally arranged chutes along the front-to-back direction. Pulleys are correspondingly installed on the first worktable 6 and the second worktable 7, and these pulleys can roll within the chutes. A separate rotary motor capable of forward and reverse rotation is used to drive the pulleys, causing the first worktable 6 and the second worktable 7 to move synchronously in opposite directions. In addition, a controller should be set up to control the start and stop of the aforementioned linear and rotary motors, so that they move and stop along a preset route. The controller adopts existing technology known in the market and does not include any improvements to the computer program. As a preferred embodiment, it can also be configured such that the first slide rail 8 and the second slide rail 9 are both support planes, the second worktable 7 is mounted on the first slide rail 8, and the first worktable 6 is mounted on the second slide rail 9. The driving mechanism includes a rotating wheel 10, a ring transmission member 11, and a first motor 12 that can rotate forward and reverse. The rotating wheel 10 is located on the front and rear sides of the base 1 and is connected to the output shaft of the motor. The rotation axis of the rotating wheel 10 is arranged horizontally in the left-right direction. The ring transmission member 11 is wound around the rotating wheel 10 on both the front and rear sides. The length direction of the ring transmission member 11 is parallel to the front-back direction. The ring transmission member 11 includes an upward advancing part 111 and a downward advancing part 112 with opposite directions of travel. The upward advancing part 111 is fixedly connected to the second worktable 7, and the downward advancing part 112 is fixedly connected to the first worktable 6. Relying on the upward advancing part 111 and the downward advancing part 112 with opposite directions of travel of the ring transmission member 11, the first worktable 6 and the second worktable 7 move synchronously and in opposite directions.

[0045] The annular transmission component 11 can be a regular belt, a synchronous belt with trapezoidal teeth on the inner side, or a chain, all of which can achieve the purpose of alternating motion. Preferably, the annular transmission component 11 and the rotating wheel 10 are provided on both the left and right sides of the first worktable 6 and the second worktable 7 to improve the stability of the motion.

[0046] The rotating wheel 10 can be a gear or a pulley.

[0047] like Figures 1 to 5As shown, the upper travel section 111 is fixedly connected to the second worktable 7, and the lower travel section 112 is fixedly connected to the first worktable 6. Taking a belt as an example, the annular transmission component 11 can be clamped onto the belt by a buckle; it can also be fixed by drilling holes in the belt and using bolts; or it can be fixed using clamps and bolts. For example, the rotating wheel 10 is a gear, and the annular transmission component 11 is a synchronous belt. The inner side of the synchronous belt has trapezoidal teeth that mesh with the gear. Both the first worktable 6 and the second worktable 7 extend with connecting portions 13, which contact the outer side of the synchronous belt. A connecting plate 14 is also included, with trapezoidal teeth on the surface of the connecting plate 14 facing the inner side of the synchronous belt. The trapezoidal teeth of the connecting plate 14 engage with the trapezoidal teeth on the inner side of the synchronous belt. The connecting portion 13 has a first connecting hole, and the connecting plate 14 has a corresponding second connecting hole. The first connecting hole and the second connecting hole are aligned and bolts are inserted. Tightening the bolts clamps the synchronous belt between the connecting portion 13 and the connecting plate 14.

[0048] like Figures 1 to 5 As shown in the above embodiment, the first worktable 6 and the second worktable 7 are positioned one above the other and have different heights. Although the workpiece clamping mechanism can be adjusted to clamp the workpieces on both worktables 6 and 7, the goal is to ensure that the workpiece clamping mechanism is at the same height for each movement, thus improving the consistency of the movements. Furthermore, the worktable on the second slide 9 of the first worktable 6 and the second worktable 7 is a lifting platform, while the other is a translational platform. The lifting platform includes a base 15 and a lifting platform 16, with a telescopic mechanism 17 between the base 15 and the lifting platform 16. The base 15 is mounted on the second slide 9, and the translational platform is mounted on the first slide 8. When the telescopic mechanism 17 is fully retracted, the lifting platform 16 is located below the translational platform. When the telescopic mechanism 17 is fully extended, the upper surface of the lifting platform 16 is at the same height as the upper surface of the translational platform. The drive mechanism drives the base 15 and the translational platform to move synchronously in opposite directions. The telescopic mechanism 17 can be an existing electrically driven telescopic mechanism 17, a hydraulically driven telescopic mechanism 17, or a pneumatically driven telescopic mechanism 17. Its specific structure will not be described in detail here.

[0049] like Figures 1 to 5 As shown, to prevent the workpiece from shifting on the first worktable 6 and the second worktable 7, positioning mechanisms are provided on both the first worktable 6 and the second worktable 7. These positioning mechanisms can be existing positioning mechanisms in the art, such as a load-bearing structure adapted to the shape of the workpiece. The positioning mechanism includes vertically arranged support columns 23 and limiting blocks 24. The support columns 23 are located on the lower surface of the workpiece and are used to support the lower surface of the workpiece. The limiting blocks 24 are distributed in a ring around the periphery of the workpiece to restrict the workpiece from moving to the surrounding areas. Multiple support columns 23 are provided, i.e., two or more, and four or more limiting blocks 24 are generally provided.
