The long-term reliability of the mechanical structure needs to be improved, and there is a lack of precise positioning of the conveyed materials, making it impossible to clean the materials and perform other processing during the continuous conveying process. Summary of the invention

[0004] The purpose of the present invention is to provide a fixture conveying channel and a fixture lifting method in view of the above-mentioned problems existing in the prior art.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0010] Furthermore, a stop surface is provided on the suspended side of the swing-type stop member, and when the swing-type stop member is swung upward around the first axis to a position, the stop surface is in an upright state.

[0011] Furthermore, the top surface of the swing-type stopper is provided with an inclined slope surface inclined from bottom to top and a plane connected to the upper side of the inclined slope surface in sequence according to the conveying direction of the conveying assembly.

[0012] Further, the jig lifting assembly enables the jig placed on the conveying assembly to be separated from the conveying assembly in the vertical direction, and at this time, the top of the swing positioning member is below the jig. Further, the swing positioning member is connected to a swing driving assembly that can drive the swing positioning member to swing around the second axis, and the swing positioning member and the housing of the swing driving assembly are hingedly connected.

[0016] The present invention also provides a jig lifting method for a jig conveying flow channel, the jig lifting method comprising the following steps:

[0017] S1. According to the conveying direction of the conveying component, the jig to be conveyed enters from the feeding side of the conveying component and is placed on the conveying component, and the conveying component runs and drives the jig to be transported in the conveying direction;

[0018] S2, the swing-type positioning member is in the jig blocking position, and the bottom of the jig conveyed by S1 contacts the top of the swing-type stop member, so as to force the swing-type stop member to swing downward in the first rotation direction around the first axis, and when the jig passes through the swing-type stop member and the front side of the jig abuts against the swing-type positioning member in the jig blocking position, the swing-type stop member swings upward in the second rotation direction around the first axis to a position and abuts against the rear side of the jig;

DETAILED DESCRIPTION

[0028] Embodiment 1

[0029] See also Figure 1 , which is a schematic diagram of a jig conveying flow channel provided by the present invention. The jig conveying flow channel includes a conveying component B11 for conveying jigs, and a swing-type stopper D10, a jig lifting component D20 and a swing-type positioning component D30 are sequentially arranged in the conveying direction of the conveying component B11. It can be imagined that the jig conveying flow channel also includes other functional components and specific structures, such as electrical connection components, control components, installation structures, etc., which are all well-known technologies to those skilled in the art, so they will not be described in detail one by one here.

[0030] The conveying assembly B11 includes a conveying frame, a conveyor belt arranged on the conveying frame, and a conveying driver that drives the conveyor belt to convey along the length direction of the conveying frame, and the conveying driver is a driving motor. In this embodiment, the conveying frame has two and is arranged at intervals, and a single drive dual output mode is adopted. A space is reserved between the two conveying frames as an installation cavity, and the installation cavity can install components such as the swing stopper D10, the fixture lifting assembly D20 and the swing positioning member D30 in the installation cavity, thereby increasing the compactness of the component installation and avoiding interference problems between the components during installation and operation. The bottoms of both sides of the fixture are overlapped on the conveying frame for conveying along the conveying direction. It should be mentioned that a protruding lateral baffle is provided on the outer side of the conveying frame to form a positioning conveying channel, which is used for directional conveying restriction in the width direction during fixture conveying.

[0031] See also Figure 2 In the present embodiment, the swing stopper D10 is a cantilever swing stopper. Specifically, a stopper base D11 is provided on the side of the swing stopper D10 away from the jig lifting assembly D20. One end of the swing stopper D10 is hingedly connected to the stopper base D11, and the other side of the swing stopper D10 is in a suspended state, i.e., the rotating movable end of the swing stopper D10.

[0032] An elastic component D12 is provided between the bottom of the suspended side of the swing stopper D10 and the stopper base D11. The elastic component D12 is usually a spring. The height of the hinged end of the swing stopper D10 and the stopper base D11 is lower than the height of the jig on the conveying assembly B11, so that the jig can pass through the swing stopper D10 normally.

[0033] It should be particularly noted that the swinging stopper D10 swings around the first axis, and the first axis is the hinge point between the swinging stopper D10 and the stopper base D11. When the swinging stopper D10 swings upward around the first axis into place under the action of the elastic component D12, at least part of the top of the swinging stopper D10 protrudes from the conveying surface of the conveying component B11. When the jig is conveyed along the conveying surface of the conveying component B11 to squeeze the top of the swinging stopper D10, the suspended end of the swinging stopper D10 is forced to be pressed down below the conveying surface of the conveying component B11, and the jig can pass through the swinging stopper D10 normally and elastically.

[0034] The top surface of the swing stopper D10 is provided with inclined slopes D14 that are inclined from bottom to top in sequence according to the conveying direction of the conveying assembly B11. The inclined slopes D14 facilitate the connection of the ends of the jigs, and the force direction thereof is more conducive to the rotation of the swing stopper D10. A connecting plane D15 is provided on the upper side of the inclined slopes D14. In this embodiment, the two connecting corners form an obtuse angle, and the smoother surface is not easy to squeeze and scratch the surface of the jig. At the same time, when the swing stopper D10 returns, it gives way, and the jig slowly disengages from the contact with the swing stopper D10 along the plane D15, avoiding the jig bouncing problem caused by the large-scale separation, and the overall conveying process of the jig is smoother.

[0035] In addition, there is a stop surface D13 on the suspended side of the swing stopper D10. When the swing stopper D10 swings upward around the first axis again under the action of the elastic component D12, the stop surface D13 is in an upright state. The stop surface D13 is higher than the conveying surface of the conveying component B11, forming a step-like barrier above the conveying surface, which is used to fit the end of the fixture away from one end of the swing positioning component D30. The plane D15 and the stop surface D13 are vertically connected. Under this structure, when the fixture is out of contact with the plane D15, the stop surface D13 instantly rises and hits the end surface of the fixture, cooperating with the swing positioning component D30 to form a blocking position for the fixture on the conveying component B11.

[0036] See also Figures 3 to 5 The swing positioning member D30 swings around the second axis. When at least part of the top of the swing positioning member D30 protrudes from the conveying surface of the conveying component B11, the swing positioning member D30 is in the fixture blocking position D50; when the top of the swing positioning member D30 is lower than the conveying surface of the conveying component B11, the swing positioning member D30 is in the fixture releasing position D60.

[0037] The swing-type positioning member D30 is connected to a swing-type driving assembly D40, and the swing-type driving assembly D40 can drive the swing-type positioning member D30 to swing around the second axis, that is, the swing-type driving assembly D40 is a control switch for the swing-type positioning member D30. The swing-type positioning member D30 and the outer shell of the swing-type driving assembly D40 are hingedly connected. Specifically, the swing-type driving assembly D40 includes a swing-type driving assembly D41, and a hinge seat D42 is provided on the top of the outer shell of the swing-type driving assembly D41. The swing-type positioning member D30 is hinged to the hinge seat D42 through a hinge shaft D43. The swing-type driving assembly D41 is a cylinder, and a telescopic rod D44 of the swing-type driving assembly D41 passes through the hinge seat D42 and abuts against the lower surface of the movable part of the swing-type positioning member D30. A torsion spring D45 is provided on the hinge shaft D43 to place the swing-type positioning member D30 in the fixture blocking position D50, and the swing-type driving assembly D41 The swing-type positioning component D30 is driven to swing from the fixture blocking position D50 to the fixture releasing position D60, and the torsion spring D45 is deformed by force to accumulate elastic potential energy, providing power for the subsequent automatic return stroke; a limiting boss D46 is provided on the top side of the hinge seat D42, and the limiting boss D46 can limit the rotation angle range of the swing-type positioning component D30 and provide a stable supporting fulcrum. When the movable part of the swing-type positioning component D30 rests on the limiting boss D46, it indicates that the swing-type positioning component D30 is in the fixture blocking position D50.

[0038] A pressing groove D47 is provided on the lower surface of the movable part of the swing positioning member D30, and the telescopic rod D44 of the swing driver D41 is at least partially pressed into the pressing groove D47, and the groove depth of the pressing groove D47 gradually decreases in the conveying direction of the conveying component B11. The elasticity generated by the torsion of the torsion spring D45 maintains a stable movable contact surface between the telescopic rod D44 and the pressing groove D47, thereby preventing the telescopic rod D44 from being separated from the swing positioning member D30 and being in contact with the swing positioning member D30.

[0039] The jig lifting assembly D20 includes a lifting driver D21 and a lifting plate D22 connected to the power end of the lifting driver D21. The lifting driver D21 drives the lifting plate D22 to rise and press against the bottom of the jig, so that the jig placed on the conveying assembly B11 is separated from the conveying assembly B11 in the vertical direction. At the same time, a positioning structure corresponding to the jig is provided on the lifting plate D22, such as a plug-in positioning structure, which can realize the circumferential positioning of the jig during the lifting process. When the jig is separated from the contact with the swing-type positioning member D30, the elastic potential energy accumulated by the torsion spring D45 forces the swing-type positioning member D30 to rotate back. At this time, the top of the swing-type positioning member D30 is below the jig and re-enters the jig blocking position D50. The swinging angle of the swinging positioning member D30 from the fixture blocking position D50 to the fixture releasing position D60 is less than 100°, which reduces the rotation stroke of the swinging positioning member D30, reduces the rotation interference of the swinging positioning member D30, and can reduce the elastic deformation of the torsion spring D45.

[0040] A positioning roller D31 is connected to the top of the swinging positioning member D30. In this embodiment, the outer wall of the positioning roller D31 protrudes from the end face of the swinging positioning member D30. In the state of the fixture blocking position (D50), the end of the fixture is directly connected to the positioning roller D31. The movable positioning roller D31 can buffer the lateral impact of the fixture. At the same time, the roller contact method can also avoid the problem of the fixture tilting up along the swinging positioning member D30 and causing the material to get stuck. The spacing between the positioning roller D31 and the swinging stopper is close to the length of the outer contour of the fixture. In addition, in the process of the fixture lifting component D20 lifting the fixture to separate from the conveying component B11, the positioning roller D31 can also reduce the friction resistance between the fixture and the swinging positioning member D30 and the swinging stopper. The entire lifting process is smooth and not easy to be damaged. In addition, the return of the fixture to the conveying component B11 provides more fulcrums at the same height to facilitate the fixture to stably separate from the lifting plate D22.

[0041] In the conveying direction of the conveying component B11, at least one set of jig limiting units formed by a swing stopper D10, a jig lifting component D20 and a swing positioning component D30 is provided in sequence and distributed in the conveying direction of the conveying component B11. It can be imagined that each jig limiting unit corresponds to a processing station, and after the jig is lifted, the jig body or the product on the jig can be dusted and cleaned. In this embodiment, it is not limited to a single jig limiting unit, and multiple jig limiting units can be set in the conveying component B11 to operate synchronously to improve work efficiency.

[0042] Embodiment 2

[0043] The present invention also provides a jig lifting method for a jig conveying flow channel, the jig lifting method comprising the following steps:

[0044] S1. According to the conveying direction of the conveying component B11, the jig to be conveyed enters from the feeding side of the conveying component B11 and is placed on the conveying component B11, and the conveying component B11 runs and drives the jig to be transported in the conveying direction;

[0045] S2, the swing positioning member D30 is at the jig blocking position D50, and the bottom of the jig conveyed by S1 contacts the top of the swing stop member D10, so as to force the swing stop member D10 to swing downward in the first rotation direction around the first axis. When the jig passes through the swing stop member D10 and the front side of the jig abuts against the swing positioning member D30 at the jig blocking position D50, the swing stop member D10 swings upward in the second rotation direction around the first axis to the position and abuts against the rear side of the jig.

[0046] S3, the jig lifting assembly D20 lifts the jig in S2 so that the jig is upwardly separated from the conveying assembly B11, and the swing positioning member D30 swings downwardly around the second axis in the first rotation direction below the jig so that the swing positioning member D30 is in the jig release position D60;

[0047] Repeating the above steps S1-S3 will lift the jigs one by one to the corresponding processing positions.

[0048] The jig conveying channel realizes precise positioning of the jig in the uninterrupted conveying component B11, improves work efficiency, and reduces the impact and friction of the jig during the conveying process. The coordination is precise and the overall service life is increased. In addition, the jig lifting method of the jig conveying channel provides a stable and reliable jig state during the jig lifting and lowering process, which facilitates jig processing and improves processing quality.
