Technical Field

[0001] This utility model belongs to the field of clamping and transferring devices, and relates to a fixture clamping and picking component and an automatic adjustment production line. Background Technology

[0002] For example, Chinese patent literature discloses an electronic assembly product production line [202220456609.X], which includes a frame, a lower flow channel set on the frame, an upper flow channel located above the lower flow channel, a lifting assembly, a lever assembly, a barcode scanning assembly, and a fixture assembly. Materials flow into or out from the lower flow channel. The lifting assembly can drive the materials to flow between the lower flow channel and the upper flow channel. The lever assembly can move the materials between the upper flow channel and the barcode scanning assembly. The fixture assembly can grip and position the materials in the fixture assembly.

[0003] The shortcomings of the above technical solution are: it does not have a clamping design to address the changes in the state of the fixture before and after adjustment, resulting in poor clamping stability of the fixture. Furthermore, it lacks a clamping reference point, leading to poor consistency in the positioning state of the fixture during batch clamping and placement. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a fixture clamping and loading assembly and an automatic adjustment production line.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0010] The clamping drive module includes a clamping drive cylinder mounted on the vertical transfer module. The clamping drive cylinder is driven to have two symmetrically arranged clamping fingers. Each clamping finger has a clamping part that extends symmetrically inward and is staggered along the width direction of the mounting frame. Each clamping part has a clamping notch. When the clamping parts on both sides overlap, the two clamping notches close together to form a stable clamping hole. Each clamping finger also has symmetrically arranged clamping grooves.

[0011] Furthermore, the mounting frame has a T-shaped cross-section structure, and the clamping drive module has two sets that are spaced apart and suspended on both sides of the mounting frame.

[0012] Furthermore, the clamping finger is provided with at least two clamping portions spaced apart along the width direction of the mounting bracket.

Detailed Implementation

[0024] Example 1, please refer to Figures 1 to 2 This is a schematic diagram of a fixture clamping and placing assembly provided by this utility model. The fixture clamping and placing assembly includes: a mounting frame 41; a horizontal transfer module 42 disposed on the mounting frame 41; a vertical transfer module 43 disposed on the horizontal transfer module 42; and a clamping drive module 44 disposed on the vertical transfer module 43. It is conceivable that this fixture clamping and placing assembly also includes other functional components and specific structures, such as electrical connection components, control components, and mounting structures, all of which are well-known to those skilled in the art and will not be described in detail here.

[0025] In this embodiment, the mounting frame 41 adopts a hoisting structure with a T-shaped cross-section, providing a mounting carrier for the horizontal transfer module 42, the vertical transfer module 43 and the clamping drive module 44, increasing the conveying height. Moreover, the T-shaped cross-section of the mounting frame 41 facilitates symmetrical and balanced installation for multi-station installation.

[0026] The horizontal transfer module 42 is located at the upper end of the mounting frame 41. Specifically, it includes a horizontal transfer motor 421 mounted on the mounting frame 41. A horizontal transfer slider 422 is provided at the output end of the horizontal transfer motor 421 and is slidably mounted along the width direction of the mounting frame 41. The horizontal transfer motor 421 drives the horizontal transfer slider 422 to achieve the horizontal displacement of the clamping drive module 44 after it clamps the fixture.

[0027] The vertical transfer module 43 includes a vertical transfer motor 431 mounted on a horizontal transfer slider 422. A vertical transfer slider 432 is mounted on the output end of the vertical transfer motor 431 and is slidably mounted in the vertical direction. The vertical transfer motor 431 drives the vertical transfer slider 432 to achieve the vertical displacement of the clamping drive module 44 after it clamps the fixture.

[0028] Ideally, both the horizontal transfer slider 422 and the vertical transfer slider 432 are connected to a cable chain 45. The cable chain 45 controls the specific travel of the horizontal transfer module 42 and the vertical transfer module 43, and also controls the horizontal displacement distance and vertical transfer distance of the clamping drive module 44. More ideally, both the horizontal transfer module 42 and the vertical transfer module 43 are equipped with a guide shaft structure 46. The guide shaft improves the accuracy of the movement guidance of the horizontal transfer module 42 and the vertical transfer module 43, and the frame on both sides of the guide shaft realizes the displacement range of the horizontal transfer module 42 and the vertical transfer module 43.

[0029] In this embodiment, the clamping drive module 44 has two sets, which are suspended and arranged at intervals on both sides of the mounting frame 41. Each clamping drive module 44 adopts an independently arranged horizontal transfer module 42 and a vertical transfer module 43 to realize multi-station clamping and loading, thereby improving work efficiency.

[0030] The clamping drive module 44 includes a clamping drive cylinder 441 disposed on the vertical transfer module 43. Two symmetrically arranged clamping fingers 442 are driven on the clamping drive cylinder 441, and the clamping drive cylinder 441 is used to drive the spacing between the two clamping fingers 442. The two clamping fingers 442 are provided with symmetrically extending inward clamping portions 443 that are staggered along the width direction of the mounting bracket 41. The clamping portions 443 are provided with clamping notches 444. It can be imagined that when the two clamping fingers 442 approach each other, the clamping portions 443 on both sides overlap and the two clamping notches 444 surround to form a stable clamping hole 445, which is suitable for positioning and clamping the column and other columnar structures on the fixture. It can also be used as the reference point position of the overall clamping and placement device. At the same time, the staggered clamping portions 443 increase the area of ​​clamping on the outer circumference of the clamping column, increase the clamping stability, reduce the clamping wobbling effect, and prevent the clamping from slipping or falling. Moreover, the double-sided clamping method of the clamping column on the fixture adopts the surrounding and gathering positioning method, which improves the clamping force of the fixture and further improves the clamping stability.

[0031] Ideally, a U-shaped shield 47 is provided on the outside of the finger clamping 442. The U-shaped shield 47 serves as a protective structure for the clamping drive module 44, preventing accidental contact from damaging the clamping accuracy of the clamping drive module 44.

[0032] More specifically, the clamping finger 442 is provided with at least two clamping portions 443 spaced apart along the width direction of the mounting bracket 41. The two or more clamping portions 443 overlap to improve their own movement accuracy and form a multi-point stable clamping on the clamping column. The clamping notch 444 includes a strip-shaped opening 444a on the inner side and an arc-shaped opening 444b at the opening end of the strip-shaped opening 444a. By changing the inner diameter of the arc-shaped opening 444b and the strip-shaped opening 444a, the vertical guide accuracy at the synchronous height of the clamping column is improved, and a horizontal guide guide accuracy is reserved when the strip-shaped hole is closed.

[0033] In this embodiment, symmetrically arranged clamping grooves 446 are also provided on the clamping finger 442. The clamping grooves 446 are located below the clamping hole 445 and vertically penetrate the clamping finger 442. The vertically penetrating clamping grooves 446 are suitable for clamping points of the jig with varying heights, specifically lifting plates. The clamping part 443 clamps the clamping column as a reference point, and simultaneously clamps the vertically varying circumferential outer wall of the lifting plate, forming a stable clamping and transfer state of the entire jig before and after adjustment.

[0034] In addition, the clamping drive module 44 is equipped with a two-stage drive cylinder, which is mounted on the vertical transfer slider 432 and drives the clamping drive cylinder 441 to move vertically. The drive stroke of the two-stage drive cylinder is used to bring the clamping drive module 44 closer to the fixture, enabling fine adjustment of the clamping height of the clamping drive module 44. The drive stroke of the vertical movement module is suitable for vertical transfer after clamping the fixture. The distinct vertical strokes of the two-stage drive cylinder and the vertical movement module facilitate independent stroke control and avoid movement interference between components.

[0035] It should be noted that the stroke drive in this embodiment requires the cooperation of sensors, such as photoelectric sensors on the guide rail and the slider. In addition, the motors, cylinders and sensors involved in this embodiment are all commercially available parts and are existing technologies. Their specific models and structures will not be described in detail here.

[0036] Example 2: This utility model also provides an automatic adjustment production line, which has the above-mentioned fixture clamping and picking components. Except for the fixture clamping and picking components, the other components are all existing technology or commercially available parts.

[0037] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
