Abstract
Description
Technical Field
[0001] This invention relates to the field of sewing machine parts processing technology, specifically to an automatic shaping device for a fixed blade. Background Technology
[0002] A sewing machine is a mechanical device that uses one or more threads to sew together two or more pieces of material (such as fabric, leather, etc.) by passing them through the fabric with the reciprocating motion of a needle and forming a continuous stitch (i.e., "sewing thread").
[0003] The sewing machine fixed blade (also known as the bottom blade) is a fixed, non-moving metal blade that works in conjunction with another movable "thread cutter" (moving blade). When it is necessary to cut the thread, the moving thread cutter moves under the drive of a mechanical or electromagnetic device, and comes into contact with the stationary fixed blade, using its sharp cutting edge to cut the top thread and / or bottom thread sandwiched in between.
[0004] Sewing machine cutters are prone to deformation during processing and heat treatment. The degree of deformation is also influenced by various factors, including the material composition of each batch, the hardness of the heat treatment, and the elasticity and plasticity of the material, exhibiting considerable uncertainty. To ensure the quality of the sewing machine cutter, it is often necessary to flatten and calibrate it during processing.
[0005] Patent CN219880970U discloses a metal workpiece flatness correction device, comprising a housing, a plurality of first telescopic rods at the top of the housing, a bracket at the top of each first telescopic rod, a fixed box at the top of the bracket, a plurality of second telescopic rods within the inner cavity of the fixed box, a fixed frame at the bottom of each second telescopic rod, a plurality of extrusion rollers arranged sequentially from front to back within the inner cavity of the fixed frame, a plurality of conveying components arranged sequentially from front to back within the inner cavity of the bracket, an adjusting component within the inner cavity of the fixed box, the bottom of the adjusting component being fixedly connected to the top of the fixed frame, and a lifting component within the inner cavity of the housing. This metal workpiece flatness correction device solves the problem that leveling machines are inconvenient to adjust the distance between the extrusion rollers and the conveying rollers during actual use, thus preventing them from flattening metal workpieces of different thicknesses.

[0019] Compared with the prior art, the present invention has the following beneficial effects:
[0020] 1. This type of fixed-blade automatic shaping equipment integrates an automatic feeding mechanism, hydraulic rods, shaping pressure plates and conveyor belts, flatness sensors, and a material drop port, forming a closed-loop automated process of "feeding → positioning → shaping → detection → sorting". Workers only need to place the workpiece to be processed on the template block of the conveyor component.

[0022] 3. In this type of fixed-blade automatic shaping equipment, the No. 1 motor drives the conveying component and the transmission component simultaneously through the transmission rod, realizing the synchronization of feeding and unloading actions, saving the purchase and maintenance costs of multiple power sources, and the synchronous action reduces the waiting time of each link, further improving the utilization rate of the equipment.
[0023] 4. This type of fixed-blade automatic shaping equipment realizes the lateral movement of the pick-and-place component through reciprocating lead screw, guide rod and moving block. The spur gear meshes with the rack plate to drive the pick-and-place component to rotate (such as from vertical state to horizontal pick-and-place), adapting to the workpiece posture requirements of different workstations.
[0024] 5. In this type of automatic shaping equipment for fixed blades, the template blocks on the chain plate are connected to the mounting holes by bolt No. 2, which allows for quick replacement of modules with different template slots to meet the positioning requirements of different models of fixed blades.

Inside the cover 2, with the bottom surface of the shaping plate 14 facing the upper surface of the second electromagnet 47, two material drop ports 15 are opened through the upper surface of the platform 1, and two material drop plates 10 are fixedly connected to the upper end of the control cabinet 4. The upper ends of the two material drop plates 10 are aligned with the two material drop ports 15 respectively, and the lower ends of the two material drop plates 10 extend through to the outside of both sides of the control cabinet 4 respectively. An automatic feeding mechanism is also connected to the upper surface of the platform 1. One end of the automatic feeding mechanism is located outside the operating cover 2, and the other end of the automatic feeding mechanism extends through the inside of the operating cover 2 and is aligned with the position of the base plate 21.

[0049] More specifically, by setting up a power mechanism, a power source can be provided to the conveying and transmission components, eliminating the need for manual operation and further improving the automation effect. Moreover, since the transmission and conveying components use the same power source, they can be started or stopped simultaneously, which not only saves energy but also reduces the error rate.

The other end of the pick-and-place assembly is aligned with both the conveying assembly and the base plate 21, and the other end of the feeding assembly is also aligned with the base plate 21.
[0053] More specifically, by setting up a reciprocating component, the workpiece on the conveying component can be automatically moved onto the bottom plate 21, improving efficiency.
[0054] As a preferred embodiment of the present invention, the moving assembly includes a rack plate 40, an inclined plate 41, a moving block 45, a spur gear 46, and a metal rod 50. The moving block 45 is sleeved on the outside of the reciprocating screw 28 and the guide rod 26.

[0055] More specifically, by setting up a moving component, when the transmission component rotates, the rotational force can be converted into a lateral movement force, and the pick-and-place component, unloading component, and workpiece can be automatically moved to a specific position.
[0056] As a preferred embodiment of the present invention, the picking and placing assembly includes a crossbar 3, a first electromagnet 32, an extension plate 36 and a mounting block 42.

[0059] More specifically, by setting up the unloading component, the workpiece that has been shaped and flattened can be removed from the base plate 21, avoiding the previous workpiece from affecting the next workpiece.

The bottom surfaces of the two No. 1 plates 5 are fixedly connected to the upper surface of the platform 1. The two ends of the two No. 1 rods 12 are rotatably connected to the inner walls of the two ends of the two No. 1 plates 5, respectively. The four sprockets 18 are respectively sleeved and fixedly connected to the outer walls of the two ends of the two No. 1 rods 12. One chain 9 and two sprockets 18 close to the same No. 1 plate 5 form a group. The chain 9 in the same group meshes with the two sprockets 18. One end of one No. 1 rod 12 is fixedly connected to the end of the transmission rod 19 away from the No. 1 motor 11.

[0061] More specifically, by setting up a conveying component, workpieces located outside the operating cover 2 can be stably conveyed into the operating cover 2, so as to facilitate the automated operation of subsequent picking and placing components and other parts;
[0062] It should be noted that the template block 8 can be changed to different models according to different workpieces (if conditions permit, only the internal template groove can be replaced). The template block 8 is fixed by fastening it to the mounting hole 7 of the chain plate 6 with bolt No. 2. Ordinary magnets can also be set on the bottom surface of the template groove to improve the stability of the workpiece inside the template groove. Of course, the magnetism of ordinary magnets is much smaller than that of electromagnet No. 1 32.
[0063] As a preferred embodiment of the present invention, two No. 2 plates 23 are fixedly connected to the upper surface of the platform 1. The first No. 2 plate 23 is in close contact with the side of the bottom plate 21 away from the chain plate 6, and the height of both No. 2 plates 23 is the same as the height of the bottom plate 21. Both ends of the two No. 2 plates 23 are rotatably connected to No. 2 rods 44.

[0064] More specifically, by setting up components such as the second plate 23, the second rod 44, the conveyor belt 22 and the second motor 24, the workpieces that are detached from the bottom plate 21 by the unloading assembly can be accurately transported into the two unloading ports 15, so that the workpieces can be discharged from inside the operating cover 2 to the outside for unified collection.
[0065] In addition, by setting up components such as L-shaped plate 16, horizontal plate 17 and flatness sensor 43, the workpiece pushed down by the unloading assembly is detected in real time, so that it can be judged as "qualified" or "unqualified" in a timely manner. Then, the workpieces with the two results can be transported to different unloading ports 15 by the second motor 24 and the conveyor belt 22 respectively.
[0066] As a preferred embodiment of the present invention, trigger blocks 49 are fixedly connected to the side of the moving block 45 away from the spur gear 46 and to both sides near the two support plates 25.

A first contact sensor 27 is fixedly connected to one side of each of the two support plates 25. The three trigger blocks 49 are respectively aligned with the second contact sensor 31 and the two first contact sensors 27.
[0067] More specifically, by setting up three trigger blocks 49, a second contact sensor 31, and two first contact sensors 27, different control effects can be achieved when the trigger blocks 49 are in contact with different contact sensors at different positions.
[0068] When using the fixed-blade automatic shaping device of the present invention, the following steps can be followed:
[0069] The worker (or external robotic arm) places the workpiece to be inspected in the template slot of the first template block 8. At this time, the workpiece is attracted and stabilized by the ordinary magnet inside the template slot. Then, the first motor 11 is started. The output shaft of the first motor 11 drives the transmission rod 19 to rotate. Subsequently, the transmission rod 19 drives the first bevel gear 20 and one of the first rods 12 connected to it to rotate.
[0070] When rod 12 rotates, it works in conjunction with another rod 12 to rotate with four sprockets 18. Then, sprockets 18 rotate with chain 9, and chain 9 moves with chain plate 6, which allows the first template block 8 and the first workpiece to move from the outside of the operating cover 2 to the inside of the operating cover 2.
[0071] While the chain plate 6 is moving the first workpiece, the first bevel gear 20 and its cooperating components are running simultaneously. When the first workpiece moves to a specific position, the first motor 11 automatically stops for a period of time (the position and the start and stop methods will be explained later). At this time, the worker can place the second workpiece in the template slot of the second template block 8 while the chain plate 6 is stopped (in the same way as above).
[0072] Then repeat the above steps until the first workpiece moves with the chain plate 6 to a position between the upright position and the previous upright position (the distance between the upright position and several template blocks 8 can be as follows). Figure 6 As shown, there are three plates between two adjacent template blocks 8. At this time, the first workpiece is located at the position of the second plate between the two template blocks 8. To put it more simply, Figure 6 For reference, the first workpiece is located in the middle of the two template blocks 8 on the left end of the chain plate 6. At this time, while the chain plate 6 is stopped, the worker continues to repeat his workpiece placement steps. After that, the first motor 11 stops for a period of time and then starts automatically. At this time, the first workpiece continues to move with the chain plate 6, while at the same time, the first bevel gear 20 drives the second bevel gear 29 to rotate.
[0073] When the second bevel gear 29 rotates, it will drive the reciprocating screw 28 located inside the upper end of the two support plates 25 to rotate. After the reciprocating screw 28 rotates, it will cooperate with the guide rod 26 to drive the moving block 45 connected to the outside of the reciprocating screw 28 and the guide rod 26 to undergo lateral displacement. At this time, the moving block 45 moves from the base plate 21 towards the chain plate 6.
[0074] When the movable block 45 moves, it will move along with the metal rod 50, which is tightly attracted by the strong magnet in the rotating hole 48. The movement of the metal rod 50 will also move along with components such as the spur gear 46, the extension plate 36, and the crossbar 3.
[0075] As the spur gear 46 moves, it comes into contact with the rack plate 40, and then the spur gear 46 rotates. This rotation causes the first electromagnet 32, which was originally facing downwards, to turn towards the chain plate 6 (e.g., from...). Figure 7 Transfer to Figure 8 (state)
[0076] Subsequently, the moving block 45 continues to move, and the first trigger block 49 on one side of the moving block 45 will first contact the second contact sensor 31 at the upper end of the upright plate 30 (e.g., Figure 9 As shown), when the second contact sensor 31 receives the signal, it immediately activates the hydraulic rod 13 through the internal controller of the control cabinet 4 (such as a PLC controller, hereinafter referred to as the controller);
[0077] After the hydraulic rod 13 is activated, its output end immediately extends downward, thereby pushing the detachable plate 33 and the shaping pressure plate 14 down (e.g. Figure 10 (As shown), then the moving block 45 continues to move. When the second trigger block 49 on the other side of the moving block 45 comes into contact with the first contact sensor 27 on the support plate 25 near the second bevel gear 29, the controller immediately shuts down the first motor 11. At the same time, the controller also turns on the first electromagnet 32 and shuts down the second electromagnet 47.
[0078] When motor 11 is turned off, the first workpiece stands upright facing electromagnet 32 (e.g.) Figure 6 As shown), at this time, because the first electromagnet 32 is energized and generates magnetism, it can instantly pull the first workpiece from the module slot of the first template block 8 (as mentioned above, the magnetic force of the ordinary magnet in the module slot is much smaller than the magnetic force of the first electromagnet 32).
[0079] After a period of stillness (e.g., five seconds), motor 11 starts automatically under the control of the controller. At this time, the chain plate 6 continues to rotate in the manner described above, which will turn the second workpiece into an upright state. Before this, the moving block 45 has moved to the end of the reciprocating screw 28 (abutting against the support plate 25). Due to the characteristics of the reciprocating screw 28 itself, the moving block 45 automatically moves in the opposite direction (i.e., it begins to move towards the base plate 21).
[0080] After the moving block 45 moves a short distance, its trigger block 49 contacts the second contact sensor 31 on the vertical plate 30 again, at which point the output end of the hydraulic rod 13 retracts instantly (as shown). Figure 9 As shown), at the same time, the push plate 34 has moved to the position of the bottom plate 21 (there is a positional difference between it and the shaping pressure plate 14, so they will not collide).
[0081] Then the reciprocating screw 28 continues to move the moving block 45. At this time, the push plate 34 slides along the surface of the base plate 21. When the moving block 45 moves to the position of the second electromagnet 47 and passes through it, until the spur gear 46 on one side of the moving block 45 contacts the rack plate 40 again (as shown in the image). Figure 8 As shown in the figure, the spur gear 46 rotates under the action of the rack plate 40;
[0082] As the spur gear 46 rotates, in conjunction with the continued movement of the reciprocating screw 28, the mounting block 42, the first electromagnet 32, and the first workpiece tightly attracted by the first electromagnet 32 can be rotated toward the base plate 21 (e.g., Figure 7 As shown), when the first workpiece is fully facing the base plate 21 and the second electromagnet 47, the third trigger block 49 of the moving block 45 will contact the second first contact sensor 27 on the support plate 25 away from the second bevel gear 29.
[0083] After the second contact sensor 27 is triggered, the controller immediately shuts down the first electromagnet 32 and turns on the second electromagnet 47. After the first electromagnet 32 is de-energized, the first workpiece that was originally attracted will be attracted by the second electromagnet 47 under the action of gravity and the attraction of the second electromagnet 47. At the same time, the second workpiece moves to the position in the middle of the two adjacent template blocks 8.
[0084] Afterwards, as the moving block 45 moves to the other end of the reciprocating screw 28, the moving block 45 begins to move towards the chain plate 6. At this time, the spur gear 46, due to the action of the rack plate 40, will rotate the first electromagnet 32, as well as the fixed rod 39, fixed block 37, and push plate 34, etc., again (from... Figure 10 Move to Figure 9 During the rotation and displacement of the push plate 34, the push plate 34 will come into contact with the first workpiece located on the base plate 21;
[0085] Because the push plate 34 is located on the right side of the first workpiece, and the push plate 34 is moving towards the left side of the workpiece, and the fixed block 37 is provided with an anti-rotation plate 35 on the side close to the chain plate 6, but there is no anti-rotation plate 35 on the side of the fixed block 37 away from the chain plate 6, and the first workpiece is tightly attracted by the second electromagnet 47, the push plate 34 will automatically rotate with the rotating rod 38 to achieve "automatic avoidance".
[0086] Then repeat the above steps. When the moving block 45 moves the second workpiece to the position of the second contact sensor 31 and continues to move, the push plate 34 will push the first workpiece that has been shaped on the base plate 21 onto the conveyor belt 22 because it is blocked by the anti-rotation plate 35 and the second electromagnet 47 has been de-energized.
[0087] The first workpiece falling on the conveyor belt 22 is detected by several flatness sensors 43 and its quality is determined. Then, the second motor 24 is turned on. The output shaft of the second motor 24 drives the second rod 44 to rotate. Then, this second rod 44, together with another second rod 44, drives the conveyor belt 22 to rotate, thereby moving the workpiece on the surface of the conveyor belt 22 to the two drop ports 15. After that, the workpiece slides down the drop plate 10 into the external collection box.
[0088] This completes the entire automation process. The only requirement is manual placement of the workpieces in the early stages. If a robotic arm is used, the entire process can be completed without human intervention, resulting in a high level of automation.
[0089] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
