[0028] Example 1, please refer to Figure 1 , which is a schematic diagram of a fixture correction flow channel mechanism and production line provided by the present invention. The fixture correction flow channel mechanism includes: a fixture base 10, a conveying and positioning flow channel 20 for conveying the fixture base 10, a clamping and placing component 40 for transferring the fixture base 10 between multiple conveying and positioning flow channels 20, and a step adjustment device 50 and a pressure plate adjustment device 60 provided on the conveying and positioning flow channel 20. It is conceivable that the fixture correction flow channel mechanism also includes other functional components and specific structures, such as electrical connection components, control components, mounting structures, etc., which are all technologies well known to those skilled in the art and will not be described in detail here.

[0029] See also Figures 2 to 3The fixture base 10 serves as the carrier of the entire fixture. In this embodiment, the fixture base 10 is L-shaped, with a rectangular block at the bottom. A product positioning tool 11 is provided at the top of the fixture base 10. The side of the fixture base 10 is a vertical block 101 for slidingly connecting the pressure plate 13. The product positioning tool 11 includes a positioning groove 111 for positioning and installing the product, and a positioning block 112 that closes the positioning groove 111.

[0030] In other embodiments, the product positioning tool 11 may also adopt a contour positioning method or a clamping positioning method.

[0031] A step adjustment module 12 is provided at the bottom of the product positioning tool 11. The step adjustment module 12 is used to adjust the center position of the product positioning tool 11. Specifically, the step adjustment module 12 includes at least two stacked adjustment plates 121. The two adjustment plates 121 are connected by a guide shaft or a vertical plug-in structure to form a horizontal motion guide. In this embodiment, the two adjustment plates 121 are connected by a concave-convex plug-in to achieve vertical guidance. Specifically, the upper end of the adjustment plate 121 at the bottom is provided with a sliding protrusion 124, and the bottom of the adjustment plate 121 at the top is provided with a sliding groove 125 for the sliding protrusion 124 to be correspondingly embedded. An adjustment shaft 122 is passed through the two adjustment plates 121, the adjustment shaft 122 is connected to one of the adjustment plates 121, and one end of the adjustment shaft 122 is connected to the other adjustment plate 121. It can be imagined that the adjustment shaft 122 is arranged on the side of the adjustment plate 121, and a protruding block 123 is provided on one side of the two adjustment plates 121. The adjustment shaft 122 is horizontally passed through the two protruding blocks 123, and the connection method of the adjustment shaft 122 is a spiral connection. The distance between the two protruding blocks 123 is adjusted by screwing the adjustment shaft 122 into the depth, thereby adjusting the relative position between the two adjustment plates 121.

[0032] Optimally, the adjustment shaft 122 is a tapered micrometer structure. The micrometer is a prior art. The purpose of the columnar structure being retractable is achieved through the end knob. The purpose of adjusting the horizontal position of the top of the adjustment plate 121 is also achieved through the subsequent step adjustment device 50 in conjunction with the rotation of the adjustment shaft 122. Setting the adjustment shaft 122 of the step adjustment module 12 at the side end and setting it horizontally can reduce space occupation and prevent subsequent adjustment components from moving and interfering, thereby facilitating automated adjustment and setting. Furthermore, the step adjustment module 12 has two groups and is vertically spaced apart on adjacent sides of the step adjustment module 12. The sliding directions of the two groups of step adjustment modules 12 are vertical, that is, the product positioning tooling 11 can be adjusted in two directions to achieve the purpose of centering the product positioning tooling 11.

[0033] In this embodiment, a pressure plate 13 capable of pressing on the upper end of the product positioning tooling 11 is provided on the jig base 10. The pressure plate 13 presses down on the product positioning tooling 11 to ensure its conveying stability. Specifically, the jig base 10 has an L-shaped cross-sectional structure. A lifting plate 14 is provided on the inner side of the vertical block of the jig base 10 through a jig guide rail 17 for sliding. A swing arm 15 is provided on the jig base 10, one end of which is connected to the lifting plate 14. The swing arm 15 is suspended in the air and naturally falls under its own gravity, so that the pressure plate 13 always keeps pressing on the upper end of the product positioning tooling 11 without the action of external force, thereby achieving the purpose of self-locking of the jig and preventing the step adjustment module 12 from self-deviating during the conveying and adjustment process, thereby avoiding the problem of errors in the automatic adjustment.

[0034] Optimally, the swing arm 15 maintains a stable state and controls the rotation stroke through an external meshing gear or a built-in torsion spring, slowing down the adjustment speed of the swing arm 15 and increasing the adjustment accuracy. The swing arm 15 is set on the fixture base 10 by rotation, and a mounting port 19 is provided on the lifting plate 14. An eccentric wheel 18 is provided at one end of the swing arm 15 and is embedded in the mounting port 19 of the lifting plate 14. After rotating the swing arm 15, the vertical height of the lifting plate 14 is adjusted by the relative position of the eccentric wheel 18 and the lifting plate 14. The pressing plate 13 is set on the lifting plate 14 and is located above the product positioning tool 11. The pressing plate 13 adjusts the height synchronously with the lifting plate 14. When the pressing plate 13 is pressed down on the product positioning tool 11, the step adjustment module 12 is locked and cannot be adjusted. When the pressing plate 13 rises to above the product positioning tool 11, the step adjustment module 12 is unlocked and can be adjusted.

[0035] In other embodiments, a drag chain connection is provided between the fixture base 10 and the lifting plate 14 for controlling the stroke, and the swing arm 15 is directly connected to the lifting plate 14 as a protruding driving end to facilitate the corresponding cooperation of the subsequent pressure plate adjustment device 60.

[0036] In this embodiment, a clamping column 16 is provided at the upper end of the jig seat 10. The clamping column 16 is arranged horizontally and located above the pressure plate 13. It can be imagined that the entire components on the jig seat 10 are located in the same three-dimensional space, the overall space occupied is small, and the center of gravity is centered for easy stable clamping and transfer.

[0037] See also Figure 4In this embodiment, the conveying and positioning channel 20 has several spaced-apart channels for a single fixture holder 10 to pass through. Specifically, the conveying and positioning channel 20 has a parallel upper channel 21 and a lower channel 22, each of which has multiple stations. Furthermore, adjustment channels 23 are arranged in parallel and staggered below the upper and lower channels 21 and 22. The number of adjustment channels 23 corresponds to the number of clamping stations in the upper and lower channels 21 and 22. The conveying and positioning channel 20 is provided with a conveyor belt and a conveying drive motor that drives the conveyor belt. Lateral baffles are provided on both sides of the conveying and positioning channel 20 to form a channel for only a single fixture holder 10 to pass through.

[0038] After the fixture base 10 is clamped by the clamping and placing assembly 40, the fixture base 10 is sequentially transferred to the loading channel 21, the adjustment channel 23, and the unloading channel 22. By operating and adjusting the two mutually offset sets of channels separately, the flow of the fixture can be automatically completed. The clamping and placing assembly 40 connects the two sets of channels in series, and the two sets of channels do not interfere with each other, thereby improving the flow efficiency.

[0039] See also Figure 5 、 Figure 6 In this embodiment, the mounting frame 41 adopts a hoisting structure. The mounting frame 41 has a T-shaped cross-sectional structure, which provides an installation carrier for the horizontal transfer module 42, the vertical transfer module 43 and the clamping drive module 44, thereby increasing the conveying height. Moreover, the mounting frame 41 has a T-shaped cross-sectional structure, which can facilitate the installation symmetry and balance for multi-station installation.

[0040] The horizontal transfer module 42 is arranged at the upper end of the mounting frame 41, and specifically includes a horizontal transfer motor 421 arranged 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 arranged along the width direction of the mounting frame 41. The horizontal transfer slider 422 is driven by the horizontal transfer motor 421 to realize the horizontal displacement of the clamping drive module 44 after clamping the fixture.

[0041] The vertical transfer module 43 includes a vertical transfer motor 431 arranged on the horizontal transfer slider 422. A vertical transfer slider 432 sliding in the vertical direction is provided at the output end of the vertical transfer motor 431. The vertical transfer slider 432 is driven by the vertical transfer motor 431 to realize the vertical displacement of the clamping drive module 44 after clamping the fixture.

[0042] Optimally, the horizontal transfer slider 422 and the vertical transfer slider 432 are both connected to a drag chain 45, which controls the specific travel range of the horizontal transfer module 42 and the vertical transfer module 43, and controls the horizontal displacement distance and vertical transfer distance of the clamping drive module 44. More optimally, the horizontal transfer module 42 and the vertical transfer module 43 are both equipped with a guide shaft guide structure 46. The guide shafts therein improve the accuracy of the movement and guidance of the horizontal transfer module 42 and the vertical transfer module 43, and the frames on both sides of the guide shafts realize the displacement range of the horizontal transfer module 42 and the vertical transfer module 43.

[0043] In this embodiment, there are two sets of clamping drive modules 44, which are suspended and installed at intervals on both sides of the mounting frame 41. In addition, each clamping drive module 44 uses a mutually independent horizontal transfer module 42 and vertical transfer module 43 to achieve multi-station clamping and placement, thereby improving work efficiency.

[0044] The clamping drive module 44 includes a clamping drive cylinder 441 provided on the vertical transfer module 43 . The clamping drive cylinder 441 drives two symmetrically arranged clamping fingers 442 . The clamping drive cylinder 441 is used to drive the distance between the two clamping fingers 442 . The two clamping fingers 442 are provided with clamping parts 443 that extend symmetrically inward and are staggered along the width direction of the mounting frame 41, and the clamping parts 443 are provided with clamping notches 444. It can be imagined that when the two clamping fingers 442 approach each other, the clamping parts 443 on both sides are staggered and overlapped, and the two clamping notches 444 are combined to form a stable clamping hole 445, which is suitable for positioning and clamping the clamping column 16 and other columnar structures on the jig, and can be used as the reference point position of the overall clamping and placing device. At the same time, the staggered clamping parts 443 increase the area of ​​the clamping on the circumferential outer wall of the clamping column 16, increase the clamping stability, reduce the clamping shaking effect, and prevent the clamping from sliding down and falling. In addition, the double-sided clamping method of the clamping column 16 on the jig in a closed and gathered positioning manner is adopted to improve the clamping force mode of the jig and further improve the clamping stability.

[0045] Optimally, a U-shaped shield 47 is provided on the outer side of the clamping finger 442 , and the U-shaped shield 47 serves as a protective structure for the clamping drive module 44 to prevent accidental contact from damaging the clamping accuracy of the clamping drive module 44 .

[0046] More specifically, the clamping fingers 442 are provided with at least two clamping portions 443 spaced apart along the width of the mounting frame 41. The staggered overlap of the two or more clamping portions 443 improves the precision of their movement, forming a multi-point stable clamping on the clamping column 16. The clamping notch 444 includes a strip-shaped opening 444a disposed on the inside, and an arc-shaped opening 444b disposed at the open end of the strip opening 444a. The varying inner diameters of the arc-shaped opening 444b and the strip opening 444a improve the vertical guidance precision of the clamping column 16 at the same height, while also preserving the horizontal guidance precision when the strip holes are closed.

[0047] In this embodiment, symmetrically arranged clamping grooves 446 are also provided on the clamping fingers 442. Clamping grooves 446 are located below the clamping holes 445 and extend vertically through the clamping fingers 442. Vertically penetrating clamping grooves 446 are suitable for fixtures with variable height clamping points, specifically, lift plates. The clamping column 16 at the clamping portion 443 serves as a reference point, synchronously clamping the vertically varying circumferential outer wall of the lift plate, thereby ensuring stable clamping and transfer of the entire fixture before and after adjustment.

[0048] 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 in vertical motion. The two-stage drive cylinder's drive stroke is used to bring the clamping drive module 44 closer to the fixture, enabling fine-tuning of the clamping height of the clamping drive module 44. The drive stroke of the vertical transfer module is suitable for vertical transfer of the fixture after clamping. Separate vertical strokes of the two-stage drive cylinder and the vertical transfer module facilitate independent control of their respective strokes, preventing interference between components.

[0049] See also Figure 7 In this embodiment, a jig positioning device 30 capable of positioning the jig seat 10 is arranged at intervals in each conveying and positioning flow channel 20, and a penetrating mounting notch 24 is provided in the middle of the conveying and positioning flow channel 20. Specifically, the jig positioning device 30 includes a jig positioning tool 31 arranged at the bottom of the conveying and positioning flow channel 20 and clamped to the bottom of the jig seat 10. The jig positioning tool 31 is a supporting plate 311 supported on the bottom of the jig seat 10. On both sides of the supporting plate 311 are provided limiting protrusions 312 extending out of the mounting notch 24 and restricted to the outside of the jig seat 10, as well as a supporting driving cylinder 32 for driving the jig positioning tool 31 to rise and fall vertically. The supporting driving cylinder 32 drives the jig positioning tool 31 to extend out of the mounting notch 24 to complete the material receiving operation of the jig seat 10 transferred by the clamping and picking assembly 40, and then lowers the height of the jig positioning tool 31 to allow the jig seat 10 to fall smoothly into the conveying and positioning flow channel 20.

[0050] In this embodiment, the jig positioning device 30 also includes a positioning drive cylinder 33 provided on one side of the conveying positioning flow channel 20, and a clamping head 34 provided at the output end of the positioning drive cylinder 33, and a positioning notch 35 is provided at the end of the clamping head 34. There is an angle between the output movement direction of the positioning drive cylinder 33 and the conveying direction of the conveying positioning flow channel 20, thereby reducing the movement interference problem caused by the clamping head 34 extending into the conveying positioning flow channel 20. In this embodiment, the clamping head 34 acts on the upper end position of the jig seat 10, and the inner wall of the positioning notch 35 is L-shaped, and the positioning notch 35 abuts against the outer wall of the corner of the vertical surface of the jig seat 10 to achieve precise clamping and positioning.

[0051] Optimally, clamping heads 34 can be provided in multiple directions on the jig base 10. For example, when there are two clamping heads 34, in this embodiment, two clamping heads 34 are provided at diagonal positions on the jig base 10. The clamping heads 34 and the positioning notches 35 act on the jig base 10 to provide lateral support and upper end limit, and cooperate with the jig positioning tooling 31 at the bottom to form multiple vertical clamping points, thereby improving the jig base 10's ability to withstand force and pressure during adjustment and preventing the jig base 10 from tilting or even falling under force.

[0052] More optimally, the positioning notch 35 on the clamping head 34 at the front end of the conveying direction is further provided with a snap-fitting protrusion 36 that abuts against the jig seat 10 in the opposite direction. The snap-fitting protrusion 36 and the inner wall of the positioning notch 35 form a recessed positioning slot 38. The opening direction of the positioning slot 38 is perpendicular to the conveying direction of the conveying positioning channel 20. It is conceivable that when the clamping head 34 at the front end of the conveying direction first connects with the jig seat 10, the positioning notch 35 on the clamping head 34, due to its L-shaped inner wall structure, abuts against the jig seat 10 on one side, while the other side with the snap-fitting protrusion 36 still maintains a gap with the jig seat 10. That is, the jig seat 10 is movably snapped into the positioning slot 38 on the vertical surface of the jig seat 10, so that the jig seat 10 has a limited axial range of movement. Then, the clamping head 34 at the rear end of the conveying direction pushes it upward obliquely until the jig seat is diagonally clamped between the two clamping heads 34 to form a horizontal circumferential limit. The fixture positioning device 30 is applied to the clamping station position in the conveying and positioning flow channel 20, as well as the adjustment station in the conveying and positioning flow channel 20, so as to maintain a stable clamping state during the fixture clamping or adjustment process.

[0053] In this embodiment, a station partition block 37 that can be vertically extended is also provided in the conveying and positioning flow channel 20. The station partition block 37 is connected to a cylinder driver for lifting and lowering drive, and can block and space each fixture holder 10 in the same conveying and positioning flow channel 20, so as to facilitate the formation of multiple stations and waiting stations in the same flow channel, thereby improving the circulation efficiency of the fixture holder 10.

[0054] In this embodiment, a step adjustment device 50 and a pressure plate adjustment device 60 are sequentially provided in the adjustment channel 23 of the conveying and positioning channel 20. The step adjustment device 50 acts on the step adjustment module 12 to adjust the top inclination of the product positioning process, and the pressure plate adjustment device 60 acts on the swing arm 15 on the lifting plate 14 to adjust the distance between the pressure plate 13 and the upper end of the product positioning tool 11, thereby ensuring sufficient space for the next process to perform product positioning and internal product operations.

[0055] See also Figure 6 In this embodiment, the pressure plate adjustment device 60 includes an adjustment cylinder 61 provided on one side of the conveying and positioning flow channel 20, and a push rod 62 provided at the output end of the adjustment cylinder 61 and capable of abutting against the swing arm 15. The adjustment cylinder 61 drives the push rod 62 to act on the swing arm 15, forcing the swing arm 15 to rotate and drive the lifting and lowering, thereby adjusting the distance between the pressure plate 13 and the upper end of the product positioning tool 11. The stroke control of the pressure plate 13 can be achieved by adjusting the stroke setting of the cylinder 61, so that the rising height of the pressure plate 13 on each fixture seat 10 remains consistent, completing the unlocking state of the step adjustment module 12. Optimally, there is an angle between the driving direction of the adjustment cylinder 61 and the vertical lifting direction of the lifting plate 14. This structural setting enables the pressure plate adjustment device 60 to be separated from the space of the conveying and positioning flow channel 20 when the fixture seat 10 is not adjusted or the adjustment is completed, thereby avoiding the problem of interference with the flow of the fixture seat 10. After the pressure plate adjusting device 60 removes the external force on the pressure plate 13 , the swing arm 15 falls and the pressure plate is synchronously pressed down onto the product positioning tooling 11 .

[0056] See also Figure 8 In this embodiment, the step adjustment device 50 includes a direct-push drive module 51, which includes a direct-push cylinder 511, a slidable direct-push guide rail 512, and a direct-push slider 513. The direct-push cylinder 511 drives the direct-push slider 513 to move along the direct-push guide rail 512. The rotation drive module 52 includes a rotation shaft 521 rotatably disposed on the direct-push slider 513 and a rotation motor 522 that drives the rotation shaft 521. The clamping drive module 53 includes a clamping drive cylinder 531 disposed at the end of the rotation shaft 521 and a clamping block 532 driven by the clamping drive cylinder 531. In the step adjustment device 50, the horizontal distance between the clamping drive module 53 and the adjustment shaft 122 is adjusted by the direct-push drive module 51. The clamping drive module 53 clamps the end of the adjustment shaft 122 via the clamping block 532, and the rotation drive module 52 cooperates with the sensor to control the number of rotations of the adjustment shaft 122. The step adjustment device 50 is set according to the number of the step adjustment modules 12. In this embodiment, there are two step adjustment devices 50 and two step adjustment modules 12 corresponding to each other, which can automatically complete the centering adjustment of the product positioning tooling 11 on the flow channel.

[0057] By automatically completing the corresponding positioning and adjustment of the fixture in the step adjustment device 50 and the pressure plate adjustment device 60, and realizing automatic adjustment through the motor and cylinder, it is only necessary to adjust the data as needed and change the corresponding parameters. This can be used for batch fixture adjustment, avoiding direct contact with the product.

[0058] It should be noted that the stroke drive in this embodiment requires the cooperation of sensors, such as the 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 here.

[0059] Example 2: The present invention also provides a production line having the jig-correcting flow path mechanism as described above. Except for the jig-correcting flow path mechanism, other components are existing technologies or commercially available parts.
