Description

Technical Field

[0001] This application relates to the field of overhead cranes, and more particularly to an overhead crane for an automated production line. Background Technology

[0002] Current automated production lines typically require overhead cranes to transport workpieces for automated processes, and gantry cranes are usually used for vertical guidance of these cranes. Currently, the guide rods of gantry cranes are usually placed on the left and right sides of the crane's travel direction, which occupies a significant portion of the width on both sides, increasing the overall footprint of the production line; furthermore, arranging the guide rods on the left and right sides is difficult in confined spaces. Utility Model Content

[0003] In order to reduce the size of automated production lines and facilitate their arrangement in confined spaces, this application provides an automated production line overhead crane.

[0004] The technical solution for an automated production line overhead crane provided in this application is as follows:

[0005] An automated production line trolley includes a guide rail system and a trolley body;

[0006] The guide rail system includes a first directional guide rail extending along the production line direction and a second directional guide rail connected to the vehicle body and extending along the height direction. The second directional guide rail is located in front of and / or behind the vehicle body and moves with the vehicle body.

[0007] The vehicle body includes a mounting frame, a traveling assembly for traveling along a first guide rail, a gripper slidably mounted on the mounting frame, and a lifting assembly for sliding the gripper along a second guide rail. The gripper is provided with a guide for guidance.

[0008] By adopting the above technical solution, this application integrates the second directional guide rail for vertically guiding the vehicle body with the vehicle body and sets the second directional guide rail in the front and rear directions of the vehicle body. The traveling component drives the vehicle body and the second directional guide rail to move together along the direction of the first directional guide rail. After moving into place, the lifting component drives the vehicle body to move along the second directional guide rail. The second directional guide rail does not occupy the space on both sides of the production line and does not increase the production line's footprint in the width direction, thus saving more space and facilitating its arrangement in narrow spaces with a narrow width.

[0009] Preferably, the second directional guide rail is a guide rod, and the guide rod is disposed on the front and rear sides of the vehicle body; or

[0010] The second directional guide rail is a guide frame, which is located at the rear of the vehicle body.

[0011] By adopting the above technical solution, the second direction guide rail uses guide rods or guide frames, which saves more space and reduces the overall size and weight of the crane.

[0012] Preferably, the lifting assembly includes a winch with a lifting strap wound around it, a lifting motor, a lifting reducer perpendicularly connected to the output shaft of the lifting motor, and a coupling connecting the lifting reducer and the winch. The coupling rotates synchronously with the winch, and the end of the lifting strap is connected to the gripper.

[0013] By adopting the above technical solution, the lifting motor starts, the winch rotates in the forward or reverse direction, and the lifting strap gradually winds around the winch to raise the gripped part and the workpiece, or the lifting strap gradually detaches from the winch to lower the gripped part and the workpiece, thereby facilitating the lifting and lowering of the workpiece.

[0014] Preferably, the guide includes a connecting rod installed on the top of the gripper and guide protrusions fixed at both ends of the connecting rod. Each of the two guide rods has a guide groove extending along its length for cooperating with the guide protrusions.

[0015] By adopting the above technical solution, the lifting and lowering of the vehicle body is limited by the cooperation of the guide protrusion and the guide groove.

[0016] Preferably, the gripping component includes a mounting rod connected to the connecting rod and automatic grippers installed at both ends of the mounting rod, wherein the mounting rod is arranged perpendicularly to the connecting rod.

[0017] By adopting the above technical solution, the connecting rod and the mounting rod are set perpendicularly, and the automatic grippers for gripping the workpiece are set at both ends of the mounting rod, so as to avoid interference with the guide rod and the automatic grippers can grip both ends of the workpiece.

[0018] Preferably, the gripper includes a support frame and a hook installed on the side of the support frame away from the mounting frame, the guide includes guide wheels installed at both ends of the gripper, and a limiting structure is provided at the bottom of the guide frame to restrict the movement of the guide wheels.

[0019] By adopting the above technical solution, the guide wheel is set on one side of the gripper and is used to clamp the two sides of the guide rod. The gripper is bent on the side away from the guide wheel to form a hook. The form of the guide wheel is used to guide the lifting and lowering of the gripper. The form of the gripper changes according to the form of the guide to avoid interference with the guide wheel and guide rod.

[0020] Preferably, the first directional guide rail is an I-shaped guide rail, and the walking assembly includes four walking wheels disposed at the four corners of the bracket for abutting against the walking space of the I-shaped guide rail, and a driving component for driving the walking wheels to rotate.

[0021] The driving component drives the two walking wheels located at the front end of the walking mechanism to rotate, and the two walking wheels are connected by a connecting shaft. The driving component includes a horizontal walking motor and a horizontal walking reducer arranged perpendicularly to the output shaft of the horizontal walking motor. The connecting shaft is connected to the horizontal walking reducer.

[0022] By adopting the above technical solution, the horizontal walking motor changes its driving direction through the horizontal walking reducer, thereby driving the two walking wheels located at the front end of the walking motor to rotate, and the two walking wheels located at the rear end of the walking motor follow suit, so that the vehicle body moves along the first direction guide rail.

[0023] Preferably, the bottom of the vehicle body is provided with a liquid receiving tray that can slide in a direction perpendicular to the guide rod. The liquid receiving tray is used to slide out to the bottom of the workpiece after the lifting assembly drives the workpiece to rise.

[0024] By adopting the above technical solution, an automatically sliding liquid receiving tray is set at the bottom of the gripper. After the workpiece is lifted, the liquid receiving tray automatically slides to the bottom of the workpiece to catch the dripping chemical liquid, thus avoiding contamination of the tank liquid in other reaction tanks. When the lifting component moves the workpiece down, the liquid receiving tray automatically slides back to its original position to avoid affecting the movement of the workpiece.

[0025] Preferably, a translation frame with a slider and extending in a direction perpendicular to the guide rod is installed at the bottom of the guide rod, and the liquid receiving tray is driven by the slider to slide along the extension direction of the translation frame;

[0026] The sliding component includes a drive motor, a synchronous pulley, and a synchronous belt mounted on the translation frame, and the liquid receiving tray is mounted on the top surface of the synchronous belt.

[0027] By adopting the above technical solution, a translation frame is set as the guide structure for the liquid receiving tray, and a sliding component is set on the translation frame to drive the liquid receiving tray to move horizontally along the translation frame. The sliding component uses a transmission method of driving a synchronous belt driven by a drive motor to move the liquid receiving tray along the horizontal frame.

[0028] Preferably, the liquid receiving tray is provided with a drain pipe connected to the outside, the drain pipe is equipped with a pneumatic diaphragm valve, and the liquid receiving tray is provided with a liquid level sensor. The pneumatic diaphragm valve automatically opens when the waste liquid in the liquid receiving tray reaches a preset liquid level height.

[0029] By adopting the above technical solution, the liquid level sensor is used to detect the liquid level in the receiving pan in real time. When the liquid level in the receiving pan reaches the preset liquid level, the pneumatic diaphragm valve is automatically opened to discharge the waste liquid in the receiving pan. When the liquid level sensor detects that the liquid level in the receiving pan is lower than the preset liquid level, the pneumatic diaphragm valve is automatically closed.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. This application integrates a second directional guide rail that guides the vehicle body in the height direction with the vehicle body, and sets the second directional guide rail on the front and rear sides of the vehicle body according to the forward direction of the vehicle body. The vehicle body and the second directional guide rail are driven by the walking component to move together along the first directional guide rail. Thus, the second directional guide rail will not occupy the space on both sides of the production line, which is convenient for arrangement in narrow spaces with a narrow width.

[0032] 2. This application provides a liquid receiving tray that can slide horizontally along a direction perpendicular to the guide rod at the bottom of the guide rod. This tray slides out to the bottom of the workpiece after the lifting assembly lifts the gripper and the workpiece to receive the liquid falling from the workpiece, thus avoiding contamination of other processing tanks.

[0037] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0038] This application discloses an automated production line overhead crane. (Refer to...) Figures 1-3 The automated production line trolley includes a guide rail system and a vehicle body 2 for gripping workpieces and moving along the guide rail system.

[0039] The guide rail system includes a first directional guide rail extending along the production line direction and a second directional guide rail 1 located on two vertical planes and extending along the height direction. The second directional guide rail 1 is connected to the vehicle body 2 and is located in front of and / or behind the vehicle body 2. The vehicle body 2 and the second directional guide rail 1 slide together along the first directional guide rail.

[0040] The vehicle body 2 includes a mounting frame 3, a traveling component 4 for traveling along a first guide rail, a gripper 42 slidably mounted on the mounting frame 3, and a lifting component 5 for sliding the gripper 42 along a second guide rail. The gripper 42 is provided with a guide 6 for guiding.

[0041] Mounting frame 3 is a square frame with one open end and an internal installation space. The traveling assembly 4 and lifting assembly 5 are integrated within this space. Lifting assembly 5 includes a winch 52 with a lifting strap 51 wound around it, a lifting motor 53, a lifting reducer 54 perpendicularly connected to the output shaft of the lifting motor 53, and a coupling 55 connecting the lifting reducer 54 and the winch 52. The coupling 55 passes inside the winch 52 and rotates synchronously with it. The end of the lifting strap 51 is connected to the gripper 42. When the lifting motor 53 starts, the winch 52 rotates forward or backward, and the lifting strap 51 gradually winds around the winch 52, causing the gripper 42 and the workpiece to rise. Alternatively, the lifting strap 51 gradually disengages from the winch 52, causing the gripper 42 and the workpiece to descend, thus facilitating the lifting and lowering of the workpiece.

[0042] The first directional guide rail is an I-shaped guide rail. The traveling assembly 4 includes four traveling wheels 41 located at the four corners of the bracket, which abut against the traveling space of the I-shaped guide rail, and a driving component 43 for driving the traveling wheels 41 to rotate. The driving component 43 drives the two traveling wheels 41 located at the front end of the traveling assembly to rotate, and the two traveling wheels 41 are connected by a connecting shaft 433. The driving component 43 includes a horizontal traveling motor 431 and a horizontal traveling reducer 432 arranged perpendicularly to the output shaft of the horizontal traveling motor 431. The connecting shaft 433 is connected to the horizontal traveling reducer 432. After the horizontal traveling motor 431 is started, the horizontal traveling reducer 432 changes the direction of the output shaft of the horizontal traveling motor 431, thereby driving the connecting shaft 433 and the traveling wheels 41 to rotate. In order to ensure the frictional resistance between the traveling wheels 41 and the I-shaped guide rail, the traveling wheels 41 can use rubber tires with anti-slip treads or gears. At the same time, teeth for meshing with gears are machined on the mating surface of the I-shaped guide rail to ensure that the traveling wheels 41 will not fall off the I-shaped guide rail.

[0043] Since the second directional guide rail 1 is integrated into the vehicle body 2, its weight directly affects the overall weight of the integrated system, thus affecting the vehicle body 2's travel speed. To reduce the overall weight, in the first embodiment, the second directional guide rail 1 uses a guide rod 11. A guide member 6 slides along the length of the guide rod 11. The guide member 6 includes a connecting rod 61 mounted on the top of the gripper 42 and guide protrusions 62 fixed to both ends of the connecting rod 61. Both guide rods have guide grooves 111 extending along their length for engaging with the guide protrusions 62. The gripper 42 then includes a mounting rod 421 connected to the connecting rod 61 and automatic grippers 422 mounted at both ends of the mounting rod 421. The mounting rod 421 is perpendicular to the connecting rod 61 to avoid interference with the guide rod 11.

[0044] In another embodiment, the second directional guide rail 1 is a guide frame 12, and is located at the rear of the vehicle body 2. The gripper 42 includes a support frame and a hook 423 mounted on the side of the support frame opposite to the mounting frame 3. The guide member 6 includes guide wheels 63 mounted at both ends of the gripper 42, which clamp the two sides of the guide rod to prevent the gripper 42 from shifting in the left and right directions. A limiting structure is provided at the bottom of the guide rod to restrict the movement of the guide wheels 63.

[0045] In this application, the limiting structure can be a liquid receiving tray 7 disposed at the bottom of the guide rod 11 to catch liquid dripping from the workpiece. The liquid receiving tray 7 can slide in a direction perpendicular to the guide rod 11, and is used to slide out to below the workpiece after the lifting assembly 5 lifts the workpiece. Specifically, a translation frame 84 with a slider 8 extending in a direction perpendicular to the guide rod 11 is mounted at the bottom of the guide rod 11. The liquid receiving tray 7 is driven by the slider 8 to slide along the extension direction of the translation frame 84. In this application, the slider 8 includes a drive motor 81, a synchronous belt 82, and a synchronous belt 83 mounted on the translation frame 84. The liquid receiving tray 7 is mounted on the top surface of the synchronous belt 83, and the liquid receiving tray 7 is driven to move back and forth by the stepping of the synchronous belt 83.

[0046] Preferably, the receiving tray 7 is equipped with a drain pipe 9 connected to the outside, and a pneumatic diaphragm valve 10 is installed on the drain pipe 9. A liquid level sensor is also installed inside the receiving tray 7. The liquid level sensor is used to detect the liquid level in the receiving tray 7 in real time. When the liquid level in the receiving tray 7 reaches a preset level, the pneumatic diaphragm valve 10 is automatically opened to discharge the waste liquid from the receiving tray 7. When the liquid level sensor detects that the liquid level in the receiving tray 7 is lower than the preset level, the pneumatic diaphragm valve 10 is automatically closed.

[0047] The implementation principle of an automated production line trolley according to an embodiment of this application is as follows: When the trolley body 2 moves, the horizontal travel motor 431 starts, causing the two travel wheels 41 located at the front end of the trolley to rotate, driving the trolley body 2 and the guide rod 11 to move together along the first direction guide rail. When the trolley body 2 moves to the corresponding processing tank, the horizontal travel motor 431 stops, and the lifting motor 53 starts, thereby driving the winch drum 52 to rotate, causing the gripper 42 and the workpiece to gradually fall down along the guide rod 11 under the action of the guide member 6. After the workpiece is processed, the lifting motor 53 rotates in the opposite direction. When the workpiece is lifted above the moving frame, the drive motor 81 starts to drive the liquid receiving tray 7 to slide below the workpiece to receive the chemical liquid dripping from the workpiece. Then the horizontal travel motor 431 starts, driving the workpiece to move above the next processing tank, and the drive motor 81 starts to drive the liquid receiving tray 7 to return to the initial position, making room below the workpiece. When the liquid level in the receiving pan 7 reaches the preset liquid level, the pneumatic diaphragm valve 10 is automatically opened to discharge the waste liquid in the receiving pan 7. When the liquid level sensor detects that the liquid level in the receiving pan 7 is lower than the preset liquid level, the pneumatic diaphragm valve 10 is automatically closed.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
