Description

Technical Field

[0001] This utility model relates to the field of automated production equipment technology, and more specifically, to a material handling mechanism. Background Technology

[0002] In the automated production process of batteries, multiple individual batteries need to be clamped at the pick-up position by clamping components and then placed at the target position for processing. The distance between the batteries at the pick-up position and the distance between the batteries at the target position are different in some processes. Therefore, a variable distance structure needs to be set on the pick-up mechanism to adjust the distance between the batteries during pick-up.

[0003] Existing variable-pitch structures typically use cylinders or lead screws to drive the clamping components to move relative to each other, thereby achieving variable pitch. This type of drive has a limited stroke. To increase the moving distance of the clamping components, the cylinder size or lead screw length needs to be increased accordingly, resulting in a larger space occupied by the material handling mechanism and making the equipment layout unfavorable. Utility Model Content

[0004] The purpose of this utility model is to provide a material handling mechanism that has a compact structure, occupies little space, and can increase the moving distance of the clamping components to meet the stroke requirements of variable pitch.

[0005] A material handling mechanism, characterized in that it comprises: a mounting plate; a fixed clamping assembly fixedly disposed on the mounting plate; a movable clamping assembly slidably connected to the mounting plate; and a pitch-changing assembly, including a driving member, a driving gear, a fixed rack, and a movable rack, wherein the fixed rack is fixedly connected to the mounting plate, the movable rack is parallel to the fixed rack and connected to the movable clamping assembly, the driving gear meshes with both the fixed rack and the movable rack, and the driving member is configured to drive the driving gear to roll along the fixed rack and drive the movable rack to move linearly.

[0006] In the above technical solution, the variable pitch component drives the movable clamping component to slide, allowing the movable clamping component to move closer to or further away from the fixed clamping component. This achieves linear, stepless adjustment of the distance between the two components, which can be adjusted according to the spacing of the workpieces being gripped. This enables the material handling mechanism to be suitable for situations where the distance between the two products changes during gripping and release, improving the material handling efficiency and applicability of the mechanism. The drive gear simultaneously meshes with both the fixed and movable racks, converting the rolling motion of the gear into the linear displacement of the movable rack. This achieves precise control of the variable pitch action, and the displacement of the movable rack is equal to the linear distance of the drive gear plus its rotational circumference, thus amplifying the stroke of the movable rack. This ensures sufficient variable pitch stroke while reducing the overall space occupied by the mechanism.

[0007] Furthermore, the driving component includes a driving part and a movable seat, the output end of the driving part is connected to the movable seat, the driving gear is rotatably connected to the movable seat, and the driving part is configured to drive the movable seat to move linearly.

[0008] In the above technical solution, the drive unit can drive the drive gear to roll along the fixed rack through the movable seat, thereby realizing the linear displacement of the movable rack. The structure is simple, the overall space occupied is small, and the transmission is stable and reliable.

[0009] Furthermore, at least one end of the moving path of the movable seat is provided with a base, and the base is provided with a limiting bolt, which is configured to be rotatable and movable along its axial direction to limit the maximum stroke of the movable seat by means of the end.

[0010] In the above technical solution, the limiting bolt and the base cooperate to achieve the physical limit of the maximum stroke of the movable seat. The position of the limit can be adjusted by rotating the limiting bolt, which is simple and convenient to operate.

[0011] Furthermore, at least one end of the moving path of the movable seat is provided with a first buffer.

[0012] In the above technical solution, the first buffer can absorb the impact force when the movable seat moves, avoid rigid collisions, protect the drive gear and rack, and extend service life.

[0013] Furthermore, it also includes a lifting assembly, which includes a lifting drive and a lifting base. The mounting plate is disposed on the lifting base, and the output end of the lifting drive is connected to the lifting base.

[0014] In the above technical solution, the lifting component can drive the lifting seat to move vertically and drive the movable clamping component and the fixed clamping component to move in the vertical direction, thereby adapting to the height of the clamping and releasing position.

[0015] Furthermore, the lifting assembly also includes a mounting base, the lifting drive is disposed on the mounting base, and at least one second buffer is provided between the mounting base and the lifting base.

[0016] In the above technical solution, the second buffer can absorb the impact force when the mounting base moves, thus avoiding rigid collisions.

[0017] Furthermore, both the fixed clamping assembly and the movable clamping assembly include a clamping assembly, which includes a clamping drive and opposing grippers. The clamping drive is configured to drive the grippers to clamp or open.

[0018] In the above technical solution, the clamping drive and the gripper work together to achieve the clamping and opening actions of the product, ensuring the stability and reliability of the clamping.

[0019] Furthermore, the mounting plate is provided with a guide rail, and the movable clamping assembly includes a slider that is slidably connected to the guide rail, with the clamping component of the movable clamping assembly disposed on the slider.

[0020] In the above technical solution, the movable clamping component guides the movement by sliding the slider with the guide rail, thus ensuring the stability of the movement.

[0021] Compared with existing technologies, the beneficial effects of this utility model are as follows: The variable pitch component drives the movable clamping component to slide, allowing it to move closer to or further away from the fixed clamping component, achieving linear stepless adjustment of the distance between them. This distance can be adjusted according to the spacing of the workpieces being gripped, enabling the material handling mechanism to be suitable for situations where the distance between the two products changes during gripping and release, thus improving the material handling efficiency and applicability. The drive gear simultaneously meshes with both the fixed and movable racks, converting the rolling motion of the gear into linear displacement of the movable rack. This achieves precise control of the variable pitch action, and the displacement of the movable rack is equal to the linear distance of the drive gear plus its rotational circumference, thereby amplifying the stroke of the movable rack. This ensures sufficient variable pitch stroke while reducing the overall space occupied by the mechanism. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0030] Please refer to Figures 1 to 4 In a preferred embodiment, the material handling mechanism of this utility model mainly includes a mounting plate 1, a fixed clamping assembly 2, a movable clamping assembly 3, and a pitch-changing assembly 4. The fixed clamping assembly 2 is fixedly mounted on the mounting plate 1, the movable clamping assembly 3 is slidably connected to the mounting plate 1, and the pitch-changing assembly 4 is mounted on the mounting plate 1 and connected to the movable clamping assembly 3. The pitch-changing assembly 4 is configured to drive the movable clamping assembly 3 to move linearly closer to or further away from the fixed clamping assembly 2. The pitch-changing assembly 4 includes a driving member 41, a driving gear 42, a fixed rack 43, and a movable rack 44. The fixed rack 43 is fixedly connected to the mounting plate 1, and the movable rack 44 is parallel to the fixed rack 43 and connected to the movable clamping assembly 3. The driving gear 42 meshes with both the fixed rack 43 and the movable rack 44. The driving member 41 is configured to drive the driving gear 42 to roll along the fixed rack 43 and drive the movable rack 44 to move linearly.

[0031] For example, the mounting plate 1 is vertically arranged, the fixed clamping component 2 and the movable clamping component 3 are located on the same side surface of the mounting plate 1, and the pitch-changing component 4 is located on the other side surface of the mounting plate 1. The pitch-changing component 4 can drive the movable clamping component 3 to slide, thereby allowing the movable clamping component 3 to move closer to or further away from the fixed clamping component 2, realizing linear stepless adjustment of the distance between the two. The distance between the movable clamping component 3 and the fixed clamping component 2 can be adjusted according to the distance of the workpiece being gripped, so that the material handling mechanism can be adapted to situations where the distance between the two products changes during gripping and release, thereby improving the material handling efficiency and applicability of the material handling mechanism.

[0032] The fixed rack 43 is fixedly connected to the mounting plate 1 by bolts. The fixed rack 43 extends horizontally and is located at the lower end of the drive gear 42. The movable rack 44 is located at the upper end of the drive gear 42 and is connected to the movable clamping assembly 3 through a connecting block. Specifically, the upper end of the mounting plate 1 is provided with a slide rail, and the connecting block is slidably connected to the slide rail. The two ends of the connecting block are respectively connected to the movable rack 44 and the movable clamping assembly 3. The drive gear 42 simultaneously meshes with the fixed rack 43 and the movable rack 44, converting the rolling motion of the gear into the linear displacement of the movable rack 44. On the one hand, this enables precise control of the pitch-changing action; on the other hand, the displacement of the movable rack 44 is equal to the linear distance of the drive gear 42 plus its rotation circumference, thereby amplifying the stroke of the movable rack 44. This ensures sufficient pitch-changing stroke while reducing the overall space occupied by the mechanism.

For example, the driving part 411 is a cylinder, which is connected to the movable seat 412 through a piston rod, and can drive the movable seat 412 to move horizontally. The driving gear 42 is rotatably connected to the movable seat 412. When the movable seat 412 moves, the driving gear 42 is horizontally displaced relative to the fixed rack 43 and rolls under the action of the fixed rack 43, thereby driving the movable rack 44 to move linearly. The structure is simple, occupies little space, and the transmission is stable and reliable.

[0034] At least one end of the moving path of the movable seat 412 is provided with a base 45, and a limiting bolt 46 is provided on the base 45. The limiting bolt 46 is configured to be rotatable and movable along its axial direction to limit the maximum stroke of the movable seat 412 at its end. In this embodiment, the base 45 and the limiting bolt 46 are located at one end of the moving path of the movable seat 412. In other possible embodiments, the base 45 and the limiting bolt 46 may be located at both ends of the moving path of the movable seat 412. The limiting bolt 46 cooperates with the base 45 to physically limit the maximum stroke of the movable seat 412. The limiting position can be adjusted by rotating the limiting bolt 46, making the operation simple and convenient.

[0035] In this embodiment, at least one end of the moving path of the movable seat 412 is provided with a first buffer 47. The first buffer 47 can be an existing buffer device. The first buffer 47 can absorb the impact force when the movable seat 412 moves, avoid rigid collisions, protect the drive gear 42 and rack, and extend service life.

[0036] The material handling mechanism in this embodiment also includes a lifting assembly 5, which includes a lifting drive 51 and a lifting seat 52. A mounting plate 1 is disposed on the lifting seat 52, and the output end of the lifting drive 51 is connected to the lifting seat 52. For example, the lifting drive 51 can be an existing linear drive device, such as a cylinder, mounted on a fixed plate, with its output end connected to the lifting seat 52. The lifting seat 52 is configured to move vertically under the drive of the lifting drive 51, thereby causing the movable clamping assembly 3 and the fixed clamping assembly 2 to move vertically, thus adapting to the height of the clamping and releasing positions.

[0037] The lifting assembly 5 also includes a mounting base 53, a lifting drive component 51 is disposed on the mounting base 53, and at least one second buffer 54 is provided between the mounting base 53 and the lifting base 52. The second buffer 54 can absorb the impact force when the mounting base 53 moves, and avoid rigid collision.

[0038] Both the fixed clamping assembly 2 and the movable clamping assembly 3 include a clamping assembly 21. The clamping assembly 21 includes a clamping drive 211 and opposing grippers 212. The clamping drive 211 is configured to drive the grippers 212 to clamp or open.
