Description

Technical Field

[0001] This utility model relates to the field of assembly equipment technology, specifically to a copper tube picking and placing device for automatic assembly equipment. Background Technology

[0002] In the field of product assembly, positioning mechanisms and clamping mechanisms are commonly used together. For example, a lifting mechanism is used to adjust the height of the clamping mechanism, and the clamping mechanism clamps the corresponding workpiece, thereby completing the docking with the matching components. Common lifting mechanisms, such as cylinders and lead screws, are mostly linear lifting types. The workpieces clamped by the corresponding clamping mechanisms also dock with the matching components along a straight path. However, some workpieces require docking along an arc path during assembly. For this, the lifting mechanism needs to be replaced with an XYZ three-way moving type, which has drawbacks such as complex structure, high cost, and inconvenient installation, and needs to be improved. Summary of the Invention

[0003] To address at least one of the aforementioned technical deficiencies, this utility model provides the following technical solution:

[0004] This application discloses a copper tube handling device for an automated assembly equipment, including a clamping mechanism, a lifting mechanism, a fixed base, a telescopic mechanism, a hook, and a connecting frame. The moving end of the lifting mechanism is connected to the fixed base to adjust its position. The fixed base is provided with a telescopic mechanism, and the moving end of the telescopic mechanism is provided with a hook. The hook includes a connecting part that docks with the telescopic mechanism and a hook end provided on the connecting part. The connecting frame is pivotally connected to the fixed base. The clamping mechanism is eccentrically provided on the connecting frame, and a protrusion is eccentrically provided on the connecting frame, with the protrusion located on the moving path of the hook end of the hook. The telescopic mechanism moves the hook, and the hook pushes the protrusion to move, simultaneously causing the connecting frame to rotate so that the clamping mechanism is in the desired position. When the telescopic mechanism drives the hook to reset, the connecting frame rotates under the action of gravity, causing the protrusion to reset.

[0005] In use, the position of the fixed seat is adjusted by the lifting mechanism, and the telescopic mechanism, in conjunction with the hook, pushes the protruding column to move, simultaneously causing the connecting frame to rotate. The position of the clamping mechanism is adjusted by the rotation of the connecting frame. After the clamping mechanism clamps the required workpiece, such as a copper tube, the lifting mechanism adjusts the fixed seat to the required position again, the telescopic mechanism resets the hook, and the connecting frame rotates under the action of gravity. During the rotation of the connecting frame, the position of the clamping mechanism is adjusted, and the position of the clamped workpiece is adjusted simultaneously, so that the clamped workpiece completes docking with the matching component with an arc-shaped movement trajectory.

[0006] Furthermore, the protrusion in the initial position abuts against the hook end of the hook, with the hook end restricting the downward movement of the protrusion. In this solution, the hook end directly limits the protrusion, simultaneously restricting the rotation of the connecting frame, which helps to improve the stability of the clamped workpiece and the matching components.

[0007] Furthermore, the connecting frame is a crank-shaped frame that extends axially along its rotation center and is equipped with a clamping mechanism. The crank-shaped connecting frame is connected to the clamping mechanism, which facilitates the clamping mechanism to clamp the workpiece and to connect the clamped workpiece with the matching components.

[0008] Furthermore, the clamping mechanism has downward-facing jaws, which facilitates clamping the workpiece and enabling the clamped workpiece to dock with the supporting components.

[0009] Furthermore, the connecting frame is pivotally connected to the fixed seat via a pivot. A limiting block is provided on the pivot, and the fixed seat is at least partially located on the moving path of the limiting block. When the limiting block abuts against the corresponding part of the fixed seat, the forward rotation of the connecting frame is restricted. Increasing the limiting block to restrict the movement of the connecting frame can better clamp the workpiece and at the same time avoid the phenomenon that the connecting frame cannot reset under the action of gravity, thereby improving the stability of operation.

[0010] Furthermore, the fixed base is provided with a sliding groove that guides and slides in conjunction with the connecting part in the hook, which helps to improve the stability of operation.

[0011] Furthermore, it also includes a column, the fixed seat is slidably connected to the column via a sliding seat, the lifting mechanism is mounted on the column and its moving end is connected to the fixed seat, the column is connected to the lifting mechanism and the fixed seat, which facilitates installation in corresponding institutions or factories.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a lifting mechanism to adjust the position of the fixed seat, and a telescopic mechanism to push the protruding column with the hook, so that the connecting frame rotates simultaneously to make the clamping mechanism clamp the workpiece in a suitable position. After the telescopic mechanism drives the hook to reset, the connecting frame resets under the action of gravity, so that the workpiece clamped by the clamping mechanism docks with the matching parts in an arc trajectory. The structure of the whole device is simplified, the cost is reduced, and it is convenient to place to cooperate with other functional mechanisms. Attached Figure Description

[0021] Example 1

[0022] like Figure 1 , Figure 2 , Figure 3 As shown, the copper tube handling device of the main automatic assembly equipment in this example includes a clamping mechanism 506, a lifting mechanism 501, a fixed base 503, a telescopic mechanism 502, a hook 504, and a connecting frame 505. The lifting mechanism 501 is such as a common cylinder, but it can also be a gear, rack and pinion type, or lead screw type driven by a motor. The moving end of the lifting mechanism 501 is connected to the fixed base 503 to adjust its position. In this example, the fixed base 503 is positioned above the lifting mechanism 501, and its height is adjusted by the lifting mechanism. Of course, the position of the fixed base in other locations can also be adjusted by the lifting mechanism.

[0023] For fixed bases, any base that can provide load-bearing and support functions is sufficient; there are no major restrictions on the configuration, and options such as... Figure 1 The rectangular body shown has a configuration with protruding side portions, and the protruding portions form shaft holes that mate with the pivot. A telescopic mechanism 502 is mounted on the fixed base 503. Telescopic mechanisms can be common types such as cylinders, lead screws, gears, or racks; this example uses a cylinder for demonstration. Figure 1 , Figure 2 As shown, the telescopic mechanism 502 is horizontally arranged, and a hook 504 is installed at the moving end of the telescopic mechanism 502. The hook 504 includes a connecting part 513 and a hook end 514 on the connecting part 513. The connecting part 513 is typically rod-shaped, but it can also be partially bent or otherwise configured. The end of the connecting part 513 is bent to form the hook end 514. Alternatively, the hook end can be formed independently and then fixed to the connecting part.

[0024] The connecting frame 505 is pivotally connected to the fixed base 503, and the clamping mechanism 506 is eccentrically mounted on the connecting frame 505. For the pivotal connection of the connecting frame, a common method is to insert a pivot 517 into a shaft hole on the fixed base 503 to form a pivotal connection. The eccentricity of the clamping mechanism can be understood as: the clamping mechanism is mounted outside the rotation center of the connecting frame. For example... Figure 1 , Figure 2 As shown, the connecting frame 505 is crank-shaped and specifically includes a radially extending frame (i.e., radial frame 515 in the figure) and a frame extending axially along its rotation center (i.e., axial frame 516 in the figure). In this example, a clamping mechanism 506 is installed on the axial frame 516, and the other end of the radial frame 515, which is opposite to the end of the axial frame 516, is fixed to the pivot 517.

[0025] The clamping mechanism 506 is a common cylinder gripper, but other clamping types can also be used. Figure 1 , Figure 2 As shown, in this example, the grippers in the clamping mechanism 506 face downwards to better clamp the workpiece below, such as the copper pipe 510. Of course, the grippers in the clamping mechanism can also face other directions as needed.

[0026] For the protruding post, the connecting bracket 505 has an eccentrically fixed protruding post 507, and the protruding post 507 is located on the moving path of the hook end 514 in the hook member 504, such as Figure 1 , Figure 2 As shown, the protruding post 507 is located on the back of the radial frame 515 in the connecting frame 505. The protruding post 507 is also located outside the rotation center of the connecting frame 505 to form an eccentric placement structure. During the process of the telescopic mechanism 502 moving the hook 504, the hook end 514 pushes the protruding post 507 on its moving path to move it. The movement of the protruding post synchronously drives the connecting frame 505 to rotate, and the position of the clamping mechanism 506 can be adjusted. If it is adjusted to a near-vertical state, the lifting mechanism 501 can move the fixed seat down or up, and the clamping mechanism 506 can move up or down to clamp the copper tube 510 at the corresponding position. The lifting mechanism can adjust the position of the clamping mechanism a second time. The telescopic mechanism 502 resets the hook 504. Under the gravity of the clamping mechanism 506 and the clamped copper tube, the connecting frame rotates and resets, the protruding post resets, and the clamped copper tube connects with the matching component below in an arc path.

[0027] The hook end 514 in the hook 504 can also abut against the protrusion 507 in the initial position. When the protrusion 507 returns to the initial position, the hook end 514 is on its path of continuing to rotate downwards. The hook end restricts the downward movement of the protrusion, forming a limit, and simultaneously restricts the connecting frame to the required starting position, thereby restricting the position of the clamping mechanism, avoiding violent collisions between the clamped copper tube and the matching components, and improving the stability of the docking.

[0028] A corresponding mechanism can be added to limit the end position of the connecting frame, so that the clamping mechanism can better clamp the copper tube. For example... Figure 1 , Figure 2 As shown, in this example, a limiting block 509 is added. The connecting bracket 505 is fixed at the first end of the pivot 517, and the limiting block 509 is placed at the last end of the pivot 517. The side portion of the fixing seat 503 is located on the moving path of the limiting block 509. The configuration of the limiting block is not limited; the specific configuration can be selected according to requirements. In this example, the limiting block 509 is a protrusion that protrudes radially outward from the peripheral wall of the pivot. For fixing the limiting block to the pivot, methods such as welding, bolt fixing, fitting, and snap-fit ​​are preferred. Figure 3 As shown, a ring is connected to the end of the limiting block 509, and the ring is fitted onto the pivot 517, either by fitting or by fastening it together with bolts or the like.

[0029] When in use, if the telescopic mechanism works with the hook to push the protruding column to move, the connecting frame will rotate forward until the limiting block on the pivot abuts against the side of the fixed seat. The connecting frame will continue to rotate forward but will be restricted. This position is the required end position. When the clamping mechanism clamps the required copper tube, the connecting frame cannot reach a balanced state at this end position. Under the action of gravity, the connecting frame will rotate backward to reset. During the reset process, the copper tube clamped by the clamping mechanism will connect to the matching device in an arc path.

[0030] Furthermore, a groove 512 can be formed on the fixing base 503 to guide and slide in conjunction with the connecting part 513 in the hook 504, such as... Figure 1 , Figure 2 In the hook 504 shown, the tail end of the connecting part 513 is located in the slide groove 512 with clearance fit. The slide groove 512 guides the movement of the connecting part 513, which can improve the stability of operation.

[0031] To facilitate factory placement or coordination with supporting facilities, additional 508 columns can be added as needed, such as... Figure 1 , Figure 2 As shown, the fixed base 503 is longitudinally slidably connected to the column 508 via the slide 511. The lifting mechanism 501 is fixed on the side of the column 508 and its moving end is connected to the corresponding part of the fixed base 503 above.

[0032] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
