The first fixing assembly 11 includes a placing table 29 for placing the workpiece main body, a first stopper 33 and a second stopper 31 coupled to the placing table 29, and a third stopper 30 movably disposed on the placing table 29. The first stopper 33 is used for positioning the workpiece from the first horizontal direction. The second stopper 31 is used to position the workpiece from the second horizontal direction. The third stopper 30 can be close to or away from the second stopper 31 in the second horizontal direction to clamp or release the workpiece body.

The handling assembly 72 includes a first engagement device for engaging a workpiece body or part and a first robot for moving the first engagement device. The handling assembly 72 is used for moving the workpiece assembly to the first fixing assembly 11 or the second fixing assembly 8 for fixing, for moving the part to a predetermined position of the workpiece body, and for moving the welded workpiece body to a predetermined position. The first welding unit 10 is used to weld the parts to the workpiece main body on the first fixing unit 11. The second welding unit 7 is used for welding the parts to the workpiece main body on the second fixing unit 8.

The production equipment also includes an automatic fillet assembly 75 for polishing the fillet of the laser cut workpiece body. As shown in fig. 12 and 1, the laser cutting assembly 74, the automatic rounding assembly 75, the bending assembly 12 and the handling assembly 72 are arranged in sequence along the conveyor assembly 1. The first fixing component 11, the second fixing component 8 and the grinding component 3 are sequentially arranged together. Wherein, laser cutting subassembly 74 places the metal sheet in laser cutting subassembly 74 through the mode of artifical material loading, and laser cutting subassembly 74 cuts the work piece body into predetermined shape with the metal sheet, then moves the work piece body and places on conveying subassembly 1, is carried for automatic fillet subassembly 75 by conveying subassembly 1. The automatic fillet component 75 moves the workpiece body into a flat chamfering center through a mechanical arm, performs chamfering operation on the workpiece body, then places the workpiece body with polished fillets on the conveying component 1, and conveys the workpiece body to the bending component 12 through the conveying component 1; the bending assembly 12 moves the workpiece body into the numerical control bending machine 14 through the mechanical arm to be bent, and then the bent workpiece body is placed on the conveying assembly 1 and conveyed to the carrying assembly 72 by the conveying assembly 1.

In the present invention, the workpiece body on the conveyor line is moved into the first fixing unit 11 by the carrying unit 72 to be fixed, so that a predetermined part is welded on the first side of the workpiece body. And the workpiece main body with the parts welded on the first side is moved to the second fixing assembly 8 by the carrying assembly 72 to weld the predetermined parts on the first surface and the second surface of the second side of the workpiece, respectively, thereby obtaining the required core clamp. And then, polishing the welded iron core clamp by using a second mechanical arm 4 to obtain a final iron core clamp. The workpiece main body is fixed through the first fixing assembly 11 and the second fixing assembly 8 respectively, the problem that the partial surface of a workpiece on the traditional positioner 35 cannot be machined is solved, the iron core clamp can be automatically produced, manpower is greatly saved, and the fixture has good practical significance.

It should be noted that, only when the iron core clamp to be processed is a dry deformation clamp, the bending step needs to be performed on the workpiece main body. The crimping assembly 12 is not operative when other types of clips are being produced. Also, the machining time is shorter because there are fewer processes in the laser cutting assembly 74, the flat panel machining center, and the numerically controlled bending machine 14. Therefore, in the present invention, the workpiece body is conveyed by the conveying assembly 1. In a preferred embodiment, a plurality of carrying assemblies 72 are respectively arranged on both sides of the conveying assembly 1, and the first fixing assembly 11, the second fixing assembly 8, the feeding assembly 9, the first welding assembly 10 and the second welding assembly 7 are matched with the carrying assemblies 72, so that the laser cutting assembly 74, the flat panel machining center and the numerical control bending machine 14 can process with the fastest power.

It is understood that the laser cutting assembly 74, the flat chamfering center, and the numerically controlled bending machine 14 are all prior art devices, and the present invention is not described in detail herein.

In an alternative embodiment of the invention, based on the above embodiment, as shown in fig. 1, the production apparatus further comprises a grinding assembly 3. The grinding assembly 3 comprises a grinding apparatus, a second engaging means 5 for engaging with the body of the workpiece, and a second robot arm 4 for moving the second engaging means 5. The grinding assembly 3 is configured to grind a predetermined position of the welded workpiece.

Specifically, after the iron core clamp is welded, the surface is inevitably uneven, and even foreign matters such as burrs exist. The welded iron core clamping piece is jointed through the second jointing device 5, the second jointing device 5 is moved through the second mechanical arm 4, and the welded iron core clamping piece is ground through grinding equipment, so that burrs on the iron core clamping piece and unevenness of a welding position are eliminated.

When the workpiece body is a dry-change clamp, the production equipment further comprises a bending assembly 12. Bending assembly 12 comprises a numerically controlled bending machine 14, a gravity positioning device 16, a third engaging device 15 for engaging the sheet metal part, and a third robotic arm 13 for moving third engaging device 15. The gravity positioning device 16 includes a positioning plate 20 inclined toward a predetermined direction, and a first positioning protrusion 21 and a second positioning protrusion 22 disposed on the positioning plate 20. The gravity positioning device 16 is configured such that a sheet metal part placed on the positioning plate 20 can slide under gravity and abut on the first positioning protrusion 21 and the second positioning protrusion 22, thereby performing positioning. The third mechanical arm 13 can move the third engaging device 15 to engage the sheet metal part on the gravity positioning device 16, and can move the sheet metal part into the numerical control bending machine 14 to be bent, so as to obtain the workpiece body of the iron core clamp.

As shown in fig. 1 to 3, since the raw material moved to the bending assembly 12 by the conveying assembly 1 at this time is a square metal plate and has not yet undergone the welding step, the temperature of the entire plate material is not high. In this embodiment, the suction is directly performed by the suction cup 17, and preferably, the third engaging means 15 includes a plurality of suction cups 17 arranged at intervals. In order to enable the numerical control bending machine 14 to accurately bend the metal plate, the metal plate needs to be positioned before being fed into the numerical control bending machine 14. Because square sheet metal is processed in the process, the sheet metal is placed on the gravity positioning device 16 by adopting the gravity positioning device 16 to slide downwards, and the two sides of the sheet metal are respectively abutted against the first positioning bulge 21 and the second positioning bulge 22 to complete positioning.

It should be noted that, only when the iron core clamp to be processed is a dry deformation clamp, the bending step needs to be performed on the workpiece main body. The crimping assembly 12 is not operative when other types of clips are being produced. It is understood that the numerically controlled bending machine 14 is prior art and belongs to prior art devices, and the present invention is not described in detail herein.

In an alternative embodiment of the invention, as shown in fig. 1, on the basis of the above-described embodiment, the production plant further comprises a conveyor assembly 1. The conveying assembly 1 is used for conveying a workpiece body along a predetermined trajectory. The third robot arm 13 and the carrier assembly 72 are disposed upstream and downstream in the conveying direction of the conveying assembly 1, respectively. It should be noted that, since the number of processes in the numerically controlled bending machine 14 is small, the processing time is short. Therefore, in a preferred embodiment, the conveying assembly 1 is used to convey the workpiece body after bending by the bending assembly 12. A plurality of conveying units 72 are disposed on both sides of the conveying unit 1, and a first fixing unit 11, a second fixing unit 8, a feeding unit 9, a first welding unit 10, and a second welding unit 7 are respectively fitted to the conveying units 72 to process the workpiece body output from the bending unit 12. So that numerically controlled bending machine 14 can perform machining with the fastest power.

In a preferred embodiment, the production plant comprises two feed assemblies 9. The two feeding assemblies 9 are respectively used for providing parts to be welded on the workpiece body for the first fixing assembly 11 and the second fixing assembly 8. The production facility includes two handling assemblies 72. One of the handling members 72 can be used to move the workpiece body from the transport member 1 to the first fixing member 11, and can also be used to move the workpiece body on the first fixing member 11 to the first transferring frame (not shown). The other of the transfer members 72 is capable of moving the workpiece from the first transfer rack to the second holding member 8 and is also capable of moving the workpiece from the second holding member 8 to the second transfer rack 6. The second robotic arm 4 can be used to move the second engaging means 5 to move the workpiece body of the second turnaround support 6 to the grinding apparatus for grinding and can also be used to move the ground workpiece to the third turnaround support 2. Preferably, the production facility further comprises a first turnaround support arranged between the first holding assembly 11 and the second holding assembly 8, a second turnaround support 6 arranged between the second holding assembly 8 and the grinding assembly 3, and a third turnaround support 2 arranged beside the second robot arm 4. Wherein the second turnaround support 6 is configured to be moved by an AGV cart.

It can be understood that the first fixing unit 11 and the first welding unit 10, and the second fixing unit 8 and the second welding unit 7 can be operated separately by supplying parts to the first fixing unit 11 and the second fixing unit 8 through the two supply units 9, and picking and placing the workpiece bodies on the first fixing unit 11 and the second fixing unit 8 through the two carrying units 72, thereby improving the working efficiency. Specifically, the first welding assembly 10 and the second welding assembly 7 are mechanical arms with welding heads mounted at the output ends, which belong to the prior art, and the present invention is not described herein again.

Preferably, the handling assembly 72 includes a horizontal linear movement member coupled to the first robot for moving the first robot in a predetermined direction to provide a greater range of movement for the first robot.

As shown in fig. 8, in an alternative embodiment of the present invention based on the above embodiment, the first bonding apparatus includes a first support 45 disposed at an end portion of the first robot arm, a first magnet holder 48 and a telescopic cylinder 53 bonded to the first support 45, a second electromagnet 47 and a probe 46 bonded to the magnet holder, a second magnet holder 49 bonded to an output end of the telescopic cylinder 53, and a third electromagnet 50 bonded to the second magnet holder 49. The first magnet base 48 is telescopically disposed on the first support 45 by a guide rod compression spring structure. The second electromagnet 47 is disposed along the first magnetic attraction direction, and the third electromagnet 50 is disposed along the second magnetic attraction direction. The first magnetic attraction direction and the second magnetic attraction direction are both perpendicular to the axial direction of the output shaft of the first mechanical arm, and the first magnetic attraction direction is perpendicular to the second magnetic attraction direction. The probe 46 is disposed along the axial direction of the output shaft of the first robot arm. The telescopic cylinder 53 is provided in a telescopic direction along the axial direction of the output shaft of the first robot arm. The second magnet seat 49 is provided with a first avoiding groove 51 facing the magnetic attraction direction away from the third electromagnet 50. A second escape groove 52 is provided at the bottom of the first escape groove 51. The first escape groove 51 is used to escape the workpiece. The second avoidance groove 52 is for accommodating a cable. Preferably, the first mechanical arm, the second mechanical arm 4 and the third mechanical arm 13 are all six-axis mechanical arms.

Specifically, the number of the second electromagnets 47 is provided in plural to provide sufficient suction force to engage on the workpiece body. The magnetic attraction direction of the second electromagnet 47 is set to be perpendicular to the axis of the output shaft of the mechanical arm, so that the workpiece main body can be adsorbed on the side face of the first jointing device, and the workpiece main body is adsorbed on the position, on the iron core clamping piece, of which no part is welded, and the magnetic attraction device has good practical significance. The probe 46 is installed on the side surface of the second electromagnet 47, and the direction of the probe 46 extends along the axial direction of the output shaft of the robot arm, so that the workpiece can be detected and positioned, the second engaging device 5 and the workpiece main body are prevented from being collided, and the method has good practical significance.

Through telescopic cylinder 53 for third electro-magnet 50 can outwards stretch out, thereby outwards protruding from first magnet seat 48, avoids when magnetism is inhaled spare part and outside object emergence interference, has fine practical meaning. When moving the parts to a predetermined position of the workpiece body, it may be necessary to extend into the groove of the profile, and therefore, a first avoiding groove 51 is provided on the second magnet holder 49 to avoid the second magnet holder 49 and the workpiece body from occurring. And the second avoidance groove 52 is arranged at the second part of the first avoidance groove 51 to install the cable, so that the contact between external objects such as sparks and the like and the cable during welding can be avoided, the control cable of the second electromagnet 47 is well protected, and the practical significance is good.

As shown in fig. 1 and 2, in an alternative embodiment of the present invention, the second joining device 5 includes a second bracket joined to the end of the second robot arm 4, and a plurality of first electromagnets disposed at intervals in the same direction on the second bracket. Wherein the first electromagnet is arranged along the axial direction of the output shaft of the second mechanical arm 4. The third bonding device 15 includes a rotation cylinder 18 bonded to the end of the third robot arm 13, a third holder 19 disposed on the rotation cylinder 18, and a plurality of suction pads 17 disposed on the third holder 19 at intervals in the same direction. Wherein the suction direction of the suction cup 17 is set along the axial direction of the output shaft of the third robot arm 13.

Specifically, the second electromagnet 47 is arranged along the axis of the output end of the second mechanical arm 4, so that the iron core clamp can be jointed at the end part instead of the side surface, and the contact between the second mechanical arm 4 and the belt sander during grinding can be avoided.

The degree of freedom of the third mechanical arm 13 can be increased by rotating the air cylinder 18 to more conveniently move the sheet metal part to be bent.

As shown in fig. 9, in an alternative embodiment of the present invention based on the above embodiment, the first revolving rack and the second revolving rack have the same structure, and each of the first revolving rack and the second revolving rack includes: the transfer stand body 54, a height increasing stand 57 and at least two first support blocks 55 disposed on the transfer stand body 54, first cushion blocks 56 disposed on the first support blocks 55, first cushion plates 58 disposed on the height increasing stand 57, and a first photosensor 59 and a second photosensor 60 disposed on the height increasing stand 57. At least two first supporting blocks 55 are respectively provided with a kidney-shaped hole, and are arranged on the turnover stand main body 54 through fasteners so as to be adjustable in a predetermined direction, and the distance between the first supporting blocks 55. The first shim plate 58 is provided with through holes. The first photosensor 59 is configured to be able to detect whether there is a workpiece above the first pad plate 58 through the through hole. The second photosensor 60 is located below the first pad 58 and does not extend beyond the vertical plane in which the sides of the first pad 58 lie. The second photosensor 60 is used to detect whether there is a workpiece above the first pad 56.

Preferably, the welding step on the first fixing unit 11 and the welding step on the second fixing unit 8 are much slower than the bending speed of the bending unit 12, and therefore, are not suitable for conveying the workpiece body between the first fixing unit 11 and the second fixing unit 8 by the conveying unit 1. Therefore, the workpiece main bodies are transited through the first turnover support and the second turnover support 6, so that the workpiece main bodies are completely separated from the conveying assembly 1 in the welding and polishing processes, and the working efficiency of the whole production equipment is prevented from being influenced. In an alternative embodiment, which is not dependent on production efficiency, the transport device can be eliminated and the workpiece body can be transferred between the bending assembly 12 and the first fixing assembly 11 in the manner of a transfer carriage.

As shown in fig. 9, the turnover frame is almost hollow so that the workpiece main body can be placed on the turnover frame to dissipate heat.

As shown in fig. 4 and 5, on the basis of the above embodiments, in an alternative embodiment of the present invention, the first stopper 33 is vertically and telescopically mounted on the placing table 29 by an air cylinder. The second stopper 31 and the third stopper 30 are horizontally mounted on the placement table 29 by cylinders in a telescopic manner. The first fixing unit 11 further includes a proximity sensor 32 and a turning positioning device 23 disposed on the placing table 29, and a second mat 28 mounted on the placing table 29 at an interval. The proximity sensor 32 detects whether or not a workpiece is placed on the placing table 29. The turning positioning device 23 includes a turning base 25 hinged to the placing table 29 by a hinge, a rotating base 27 rotatably disposed on the turning base 25, a rotating driving member 26 disposed on the turning base 25 for driving the rotating base 27 to rotate, a fourth electromagnet disposed on the rotating base 27 for engaging with the workpiece, and a second supporting block 24 disposed on the placing table 29 for supporting the turning base 25.

Specifically, the first stopper 33, the second stopper 31 and the third stopper 30 are used for fixing the bent channel steel workpiece main body, and the turnover positioning device 23 is used for fixing the flat plate workpiece main body.

As shown in fig. 6 and 7, in an alternative embodiment of the present invention based on the above embodiment, the positioner 35 includes a beam 37, and a driving member 38 and a driven member 36 respectively disposed at two ends of the beam 37. Wherein the driving member 38 and the driven member 36 cooperate to drive the beam 37 in rotation. The clamping device 34 includes a fixed support seat 44 disposed on the cross beam 37, two movable support seats 41, a linear driving member engaged with the two movable support seats 41, two clamping blocks 39 and two fourth stoppers 40 respectively disposed on the two movable support seats 41, and a first linear driving member 42 disposed on the fixed support seat 44 and a pressing block 43 engaged with the first linear driving member 42. The linear driving component comprises two lead screw sliding table guide rail modules which are respectively connected between the two movable supporting seats 41 and the cross beam 37, and a motor which is in transmission connection with the two lead screw sliding table guide rail modules. The clamping block 39 and the movable support 41 form an acute angle therebetween for clamping to the workpiece body when the two movable supports 41 are brought close to each other. The fourth limiting block 40 and the pressing block 43 are respectively located at two sides of the clamping block 39, and the pressing block 43 can be driven by the first linear driving element 42 to approach or separate from the fourth limiting block 40 so as to clamp or release the workpiece body.

Specifically, the iron core clamping piece is a long strip-shaped workpiece. The positioner 35 of the present invention is therefore primarily used to rotate a workpiece so that its different surfaces to be welded are disposed upwardly. And since the parts are to be welded to the surface of the workpiece, the contact area of the clamping device 34 and the workpiece is as small as possible. In the present embodiment, the two ends of the workpiece in the length direction are fixed by the V-shaped structures on the two sides, and the fourth limiting block 40 arranged on the movable supporting seat 41 and the pressing block 43 on the fixed supporting seat 44 fix the workpiece in the width direction, so as to reduce the contact area between the clamping device 34 and the workpiece, and accurately center and position the workpiece.

As shown in fig. 10 and 11, in an alternative embodiment of the present invention based on the above embodiment, the stack device includes a material support 62 and a support plate 61 mounted on the material support 62. Wherein the support plate 61 is obliquely arranged. The feeding device comprises a first baffle 67, a second baffle 68 and a baffle seat 73 which are arranged on the supporting plate 61, a telescopic member 65 arranged on the baffle seat 73, a stop lever 64 jointed with the telescopic member 65, a stop sheet 66 jointed with the stop lever 64 and a gravity block 63 positioned in the trough. Wherein, a trough is formed among the first baffle 67, the second baffle 68 and the support plate 61. The side of the second baffle 68 facing the trough is provided with a profiling structure which is similar to the appearance of the parts. The bar 64 is parallel to the first stop 67. A gap through which parts pass is provided between the stopper 64 and the first shutter 67 and the support plate 61. The telescopic member 65 is used to adjust the gap between the stop lever 64 and the supporting plate 61 to fit different types of parts. The baffle plate 66 is disposed at the end of the baffle rod 64 and has a gap with the second baffle plate 68 for one component to pass through. The weight block 63 is provided with a third escape groove through which the blocking lever 64 passes. The weight block 63 is configured to be slidable along the axial direction of the stop lever 64 to abut the component in the magazine to urge the component against the second stop plate 68. Optionally, the feeding device further comprises a second linear driving member 71 disposed on the material support 62, and a profile block 70 coupled to the second linear driving member 71. Wherein, the copying block 70 is provided with a copying groove 69 for embedding a part. The second linear actuator 71 is disposed below the support plate 61. The support plate 61 is provided with a through hole for the passage of the copying block 70, which is located at the point where the chute is close to the second shutter 68. The second linear drive 71 is capable of telescopic movement to cause the profile block 70 to extend upwardly from the trough to drive a component to be lifted from the trough.

When the parts are in a U-shaped structure and the like, the third electromagnet 50 can be directly magnetically attracted and connected on a vertical plane, and the second linear driving piece 71 and the copying block 70 do not need to be arranged. The carrier assembly 72 can remove the parts to be welded directly from the gap between the stop plate 66 and the second stop plate 68. While some sheet-shaped workpieces or angle iron workpieces can only be placed in the trough in a laminated mode, because the cross-sectional area of the third electromagnet 50 is large, the parts cannot be directly magnetically attracted and jointed, and the parts need to be pushed out of the trough and then magnetically attracted and jointed on the side surfaces of the workpieces.

The distance between the stop lever 64 and the supporting plate 61 is adjusted through the telescopic member 65, so that the telescopic member can adapt to more types of parts and has good significance.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
