Description

Technical Field

[0001] This technical solution relates to the field of motor technology, specifically referring to a snap-fit ​​machine. Background Technology

[0002] During the processing of motor stator cores, silicon steel sheets need to be stacked together, and then the sheets are pressed onto the side walls of the stator core using a sheet-fastening machine. For example, a stator core sheet-fastening assembly device disclosed in Chinese Patent CN202011371699.4 requires manual placement of a pre-ordered quantity of silicon steel sheets onto the guide posts of the sheet-fastening machine, then placing the sheets into the grooves on the outer ring of the stator core, and finally pressing the sheets into place using the sheet-fastening machine.

[0003] However, existing chip-gluing machines still have some shortcomings:

[0004] 1. Existing snap fastener machines have limited functionality and require multiple stations or equipment to weigh the stator, cut, bend, and shape the snap fasteners, as well as press them into place. Multiple machines occupy a large area, and manual material movement between multiple machines is required, resulting in low production efficiency.

[0005] 2. The existing process requires manual loading of stacked silicon steel sheets, manual adjustment of the groove position on the side wall of the stator core, and unloading of the stator core after pressing and fastening the laminations, resulting in low production efficiency and high production costs.

[0006] 3. After the silicon steel sheets are stacked, they are weighed and the weight is adjusted to meet the set value by hand, which results in low production efficiency. In addition, manual weighing can easily lead to inaccurate production quality and reduce the yield of good products.

[0007] 4. When pressing the fasteners onto the stator core, using a single pressing device to press the fasteners onto the side wall of the stator core causes the guide post passing through the stator core to bend and deform under unilateral stress, affecting the installation of the fasteners.

[0045] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings. See also Figures 1-22 .

[0046] A clip-on machine includes: a frame 1 with a worktable 11 mounted thereon; a stator feeding device 2 mounted on the worktable 11 for feeding stator core 100 and moving the stator core 100 to a set position on the worktable 11; and a weighing device 10, which is a weighing device such as a platform scale or electronic scale, which is existing technology, mounted on the frame 1 for weighing the stator core 100 moved by the stator feeding device 2, ensuring that the weight of the stator core 100 meets the set weight before the corresponding clip-on 101 pressing operation is performed. The screening device 3, installed on the workbench 11, is used to screen out stator cores 100 whose weight exceeds a set weight. Overweight stator cores 100, after being weighed by the weighing device 10, are removed from the stator feeding device 2 when passing through the screening device 3, thus no longer being transported by the stator feeding device 2. The rotary positioning device 4, installed on the workbench 11, is used to rotate the stator cores 100 moved from the stator feeding device 2 to a set angle, thereby ensuring the accurate positioning of the subsequent fasteners 101 and ensuring that the replenishing device 5... The silicon steel sheet 103 is positioned at an accurate angle on the stator core 100. The feeding device 5, installed on the worktable 11, is used to increase the weight of the stator core 100 in the rotary positioning device 4 to a set weight. After weighing by the weighing device 10, the system software calculates the number of missing silicon steel sheets 103, and then the feeding device 5 performs the corresponding number of feedings, adding one silicon steel sheet 103 at a time for multiple feedings. The material handling and clamping device 6, installed on the worktable 11, is used to clamp the stator core 100 in the rotary positioning device 4 to the set weight. The core 100 is removed and pressed to ensure that the silicon steel sheets 103 are pressed tightly after stacking. The fastener feeding device 8, which is installed on the workbench 11, is used to feed the fastener 101 into the fastener pressing device 7. The fastener pressing device 7, which is installed on the workbench 11, is used to press and fix the fastener 101 onto the stator core 100 in the material taking and pressing device 6, thereby realizing the assembly of the fastener 101 and the stator core 100.

[0047] The stator feeding device 2 includes: a conveyor belt mechanism 21, which is prior art, mounted on the frame 1, used to move the stator core 100 to the workbench 11.

The pushing mechanism 22 has a fork 228 for pushing the stator core 100 into the weighing device 10, and a fork 229 for pushing the stator core 100 into the weighing device 10. The material is moved to the rotary positioning device 4; the second pushing mechanism 23 is installed on the workbench 11 and is used to move the stator core 100 from the weighing device 10 to the screening device 3; when the conveyor belt mechanism 21 moves the stator core 100 to the front end of the fork 228 of the first pushing mechanism 22, the fork 228 pushes the stator core 100 into the weighing device 10, and then the second pushing mechanism 23 pushes the stator core 100 into the screen device 3 (i.e., the transfer area 12 of the workbench 11), and the fork 229 pushes the stator core 100 that is not overweight into the rotary positioning device 4.

[0048] The pusher mechanism 22 can be driven by two power sources or by the same power source. In this design, the pusher mechanism 22 includes: a slide rail 221 mounted on the worktable 11, with a slider 222 slidably mounted on the slide rail 221; and a push plate 223 mounted on the slider 222, with a pusher fork 228 and a pusher fork 229 mounted on the push plate 223. The front end of the pusher fork 228 has a limiting groove 224, and the front end of the pusher fork 229 has a limiting groove 225. The side wall of the limiting groove 224 away from the discharge end of the conveyor belt mechanism 21 has a limiting part 226, which prevents the stator core 100 conveyed by the conveyor belt mechanism 21 from falling off the limit. The stator core 100 is moved out of the slot 224 to ensure the accuracy of the feeding position. The drive component 227, which is a cylinder, linear motor or push rod, is installed on the worktable 11 and the drive end of the drive component 227 is movably connected to the push plate 223. When the stator core 100 moves from the conveyor belt mechanism 21 into the limiting slot 224 and movably abuts against the limiting part 226, the drive component 227 drives the push plate 223 to move, so that the stator core 100 moves to the weighing device 10. The pusher mechanism 23 moves the stator core 100 from the weighing device 10 to the transfer area 12 on the worktable 11. Then, the limiting slot 225 of the push plate 223 pushes the stator core 100 in the transfer area 12 to the rotary positioning device 4.

[0049] The second pushing mechanism 23 includes: a slide rail 231, which is mounted on the worktable 11, and a slider 232 is slidably arranged on the slide rail 231; a push plate 233, which is mounted on the slider 232, and a limiting groove 3 234 is provided on the push plate 233; a driving component 235, which is a cylinder, a linear motor or a push rod, is mounted on the worktable 11, and the driving end of the driving component 235 is movably connected to the push plate 233; the driving component 235 pushes the push plate 233 to move, so that the stator core 100 is placed in the limiting groove 3 234, and the stator core 100 is moved from the weighing device 10 to the transfer area 12 of the worktable 11; the limiting groove 1 224, the limiting groove 225 and the limiting groove 3 234 are all adapted to the side wall shape of the stator core 100 and are arc-shaped.

[0050] The workbench 11 is provided with an elongated hole 13; the screening device 3 includes: a slide rail 31, which is installed at the lower end of the workbench 11, and a slider 32 is slidably mounted on the slide rail 31; a drive component 33, which is a cylinder, an electric push rod, or a linear motor, which is installed at the lower end of the workbench 11, and the drive end of the drive component 33 is movably connected to the slider 32; and a drive component 4 34, which is a cylinder, an electric push rod, or a linear motor, which is installed on the slider 32, and a push rod 35 is installed on the drive end of the drive component 4 34, the upper end of the push rod 35 being movably inserted into the elongated hole 13 on the workbench 11. It can extend out of the upper end of the worktable 11; when the upper end of the push rod 35 extends out of the upper end of the worktable 11, the driving component 33 drives the slider 32 to move, thereby driving the push rod 35 to move in the elongated hole 13, so that the push rod 35 pushes the stator core 100 out of the transfer area 12 of the worktable 11, thereby removing the overweight stator core 100 and preventing the shift fork component 229 from pushing the overweight stator core 100 into the rotary positioning device 4. When screening is not required, the upper end of the push rod 35 does not extend out of the upper end of the worktable 11, that is, it retracts into the elongated hole 13.

[0051] The slider 32 is provided with a mounting plate 36, which is movably connected to the drive end of the drive component 33. The drive component 4 34 is installed on the mounting plate 36, and the push rod 35 slides through the mounting plate 36, ensuring the stability of the push rod 35 when it moves up and down.

[0052] The rotary positioning device 4 includes: a rotation mechanism 41, which is mounted on the worktable 11 and used to rotate the stator core 100 to a set angle, thereby ensuring that the groove 102 on the side wall of the stator core 100 is facing correctly and that the locking tab 101 can be accurately pressed into the groove 102; a pressing mechanism 42, which is mounted on the worktable 11 and located above the rotation mechanism 41, and used to press the stator core 100 onto the rotation mechanism 41, ensuring that the silicon steel sheets 103 of the upper and lower parts of the stacked stator core 100 can rotate synchronously; and a sensing mechanism. 43, which is installed on the workbench 11, is used to sense the rotation angle of the stator core 100 and ensure that the groove 102 is facing correctly; the rotation mechanism 41 includes: a driving component 411, which is a motor or a rotary cylinder, which is installed at the lower end of the workbench 11; a rotating seat 412, which is rotatably disposed inside the workbench 11, and the upper end surface of the rotating seat 412 does not protrude from the upper end surface of the workbench 11, and the rotating seat 412 is installed on the driving end of the driving component 411; the stator core 100 moves from the upper end surface of the workbench 11 to the upper end of the rotating seat 412 under the push of the pushing mechanism 22.

[0053] The pressing mechanism 42 includes: a slide rail 421, which is vertically mounted on the support frame 14 at the upper end of the worktable 11, and a slider 422 is slidably mounted on the slide rail 421; a pressing frame 423, which is mounted on the slider 422; a pressing die 424, which is rotatably mounted at the lower end of the pressing frame 423, for pressing the stator core 100 onto the rotating mechanism 41; and a driving component 425, which is a linear motor, an electric push rod, or a cylinder, mounted on the support frame 14, and the driving end of the driving component 425 is movably connected to the pressing frame 423 for driving the pressing frame 423. The mold moves downward, causing the first mold 424 to press against the upper end of the stator core 100. The first mold 424 has an insertion part 4241 and a pressing part 4242. The insertion part 4241 is used to insert into the stator core 100 and move against the inner wall of the stator core 100. The pressing part 4242 is used to move against the upper end of the stator core 100. The lower edge of the insertion part 4241 has a guide surface 4243 for guiding the insertion part 4241 into the stator core 100. The first mold 424 and the lower pressure frame 423 are rotatably connected by bearings or annular groove protrusions.

[0054] The sensing mechanism 43 includes: a moving component 431, which is mounted on the worktable 11; a sensor 432, which is mounted on the moving component 431; and a sensing element, which is mounted on the sensor 432. When the moving component 431 drives the sensing element to move and abut against the side wall of the stator core 100 and is not placed in the groove 102, the sensing element and the sensor 432 are in a first trigger state. At this time, the rotation mechanism 41 needs to work to rotate the stator core 100. When the rotation mechanism 41 drives the stator core 100 to rotate, so that the end of the sensing element is placed in the groove 102 on the side wall of the stator core 100, the sensing element and the sensor 432 are in a second trigger state. At this time, the rotation mechanism 41 stops working.

[0055] The specific structure of the sensing element is as follows: a spring plate 433, the rear end of which is movably connected to the sensor 432, and the front half of the spring plate 433 movably abuts against the sensing part 4321 of the sensor 432; a roller 434, which is rotatably disposed at the front end of the spring plate 433; when the moving component 431 drives the roller 434 to movably abut against the side wall of the stator core 100, the front half of the spring plate 433 undergoes elastic deformation and abuts against the sensing part 4321 of the sensor 432, and the sensing element and the sensor 432 are in the first trigger state. At this time, the rotating mechanism 41 performs rotation operation. When the rotating mechanism 41 drives the stator core 100 to rotate, the elastic deformation of the spring plate 433 causes the roller 434 to movably place in the groove 102 of the side wall of the stator core 100, the front half of the spring plate 433 and the sensing part 4321 separate, and the sensing element and the sensor 432 are in the second trigger state, and the rotating mechanism 41 stops working.

[0056] Alternatively, the specific structure of the sensing element is as follows: a fixed base 435, which is mounted on the movable component 431, and a sliding groove 4351 is provided inside the fixed base 435; the sensor 432 is mounted on the fixed base 435 or the movable component 431; a sliding member 436, which is slidably disposed in the sliding groove 4351, and the front end of the sliding member 436 extends movably beyond the front end of the fixed base 435; the rear end of the sliding member 436 has a sensing part 4361, which is in sensing contact with the sensor 432; an elastic member, which is a tension spring or rubber band, one end of which is movably connected to the sliding member 436, and the other end is movably connected to the fixed base 435, for giving the front end of the sliding member 436 a tendency to extend beyond the front end of the fixed base 435; when the movable component 431 drives the fixed base 435 closer to the stator... When the stator core 100 is in operation, the front end of the sliding member 436 moves against the side wall of the stator core 100 and overcomes the force of the elastic member, causing the front end of the sliding member 436 to retract into the sliding groove 4351. This causes the second sensing part 4361 to separate from the first sensing part 4321 of the sensor 432. The sensing member and the sensor 432 are in the first triggered state, and the first rotating mechanism 41 is in the working state. When the first rotating mechanism 41 drives the stator core 100 to rotate, the elastic member causes the front end of the sliding member 436 to extend out of the front end of the fixed seat 435 and be placed in the groove 102 of the side wall of the stator core 100. This causes the first sensing part 4321 and the second sensing part 4361 to make contact. The sensing member and the sensor 432 are in the second triggered state, and the first rotating mechanism 41 stops working.

[0057] The moving component 431 includes: a slide rail 4311, which is mounted on the worktable 11, and a slider 4312 is slidably disposed on the slide rail 4311, the slider 4312 being movably connected to the sensor 432 or the fixed base 435; and a driving component 4313, which is a cylinder, a linear motor or an electric push rod, mounted on the worktable 11, and the driving end of the driving component 4313 being movably connected to the slider 4312, for driving the sensor 432 and the sensing element to approach the side wall of the stator core 100 located in the rotating mechanism 41.

[0058] The slider 4312 is provided with a mounting plate 4314, the front end of which is movably connected to the sensor 432 or the fixed seat 435; the moving component 431 also includes: a mounting block 4315, which is mounted on the worktable 11; a limiting rod 4316, which is a screw or an elastic buffer, is movably connected to the mounting block 4315, and the end of the limiting rod 4316 movably abuts against the slider 4312 or the mounting plate 4314 to prevent the sensor 432 or the fixed seat 435 from having excessive pressure on the side wall of the stator core 100 in the rotating mechanism 41.

[0059] The feeding device 5 includes: a hopper 51, which is installed on the workbench 11 and used to store silicon steel sheets 103; and a feeding mechanism 52, which is installed on the workbench 11 and located beside the hopper 51, for placing the silicon steel sheets 103 in the hopper 51 onto the stator core 100 in the rotary positioning device 4. When the weight of the stator core 100 in the rotary positioning device 41 is lower than the set weight, that is, when the stator core 100 is short of several silicon steel sheets 103, the feeding mechanism 52 increases the weight by placing one silicon steel sheet 103 at a time. The feeding mechanism 52 performs several feedings, which are then weighed by the weighing device 1. Weighing, the system calculates the difference, and then converts the difference into the number of silicon steel sheets 103. Each silicon steel sheet 103 has the same weight and size, but the silicon steel sheets 103 stored in hopper 51 are flat and do not have grooves or positioning protrusions on their surface. However, the stator core 100 in the rotary positioning device 4 consists of several silicon steel sheets 103 with grooves and positioning protrusions stacked together, and the uppermost silicon steel sheet 103 has a groove on its upper end surface. Adjacent silicon steel sheets 103 are positioned by the grooves and positioning protrusions, while preventing the stator core 100 from falling apart when moving. The feeding mechanism 52 includes: a slide rail. A slide rail 53 is mounted on the workbench 11, and a slider 531 is slidably mounted on the slide rail 53; a drive component 54, which is an electric push rod, linear motor, or cylinder, is mounted on the workbench 11, and the drive end of the drive component 54 is movably connected to the slider 531; a mounting bracket 55 is mounted on the slider 531; a slide rail 56 is vertically mounted on the mounting bracket 55, and a slider 561 is slidably mounted on the slide rail 56; a material picking component 57 is mounted on the slider 561, and the front end of the material picking component 57 is provided with a suction component or a clamping component for sucking up or clamping the material in the material bin 51. The silicon steel sheet 103 has an electric magnetic disk or suction cup as the suction component and a gripper cylinder as the clamping component. The drive component 8 58 is an electric push rod, linear motor or cylinder, which is mounted on the mounting bracket 1 55, and the drive end of the drive component 8 58 is movably connected to the slider 7 561. The hopper 1 51 is provided with several positioning posts 511, which are used to insert into the coil groove 104 inside the silicon steel sheet 103 to position the silicon steel sheet 103 and ensure that the side wall groove 102 of the silicon steel sheet 103 in the hopper 1 51 corresponds and matches the angle position of the side wall groove 102 of the stator core 100 in the rotating mechanism 1 41.

[0060] The material handling and pressing device 6 includes: a bottom mold mechanism 61, which is installed on the workbench 11 and whose upper end face does not protrude from the upper end face of the workbench 11; a material transfer mechanism 62, which is slidably mounted on the support frame 14 on the workbench 11 and is used to move the stator core 100 in the rotary positioning device 4 to the bottom mold mechanism 61; a pressing mechanism 63, which is installed on the support frame 14 and located above the bottom mold mechanism 61 and is used to press the upper end of the stator core 100 to press the stacked silicon steel sheets 103 firmly; and a positioning mechanism 64, which is installed at the lower end of the workbench 11 and whose positioning mold 642 passes through the bottom mold mechanism 61 and is movably inserted into the stator core 100 to position the pressing stator core 100 and prevent the pressing stator core 100 from rotating or moving.

[0062] The material transfer mechanism 62 includes: a slide rail 621, which is mounted on the support frame 14, and a slider 622 is slidably disposed on the slide rail 621; a mounting frame 623, which is mounted on the slider 622; a drive component 624, which is a cylinder, a linear motor, or an electric push rod, which is mounted on the support frame 14, and the drive end of the drive component 624 is movably connected to the mounting frame 623, and the drive component 624 is used to drive the mounting frame 623 to move horizontally; and a slide rail 625, which... The device is vertically mounted on mounting bracket 3 623, and a slider 9 626 is slidably mounted on slide rail 9 625; mounting bracket 4 627 is mounted on slider 9 626; mold 2 628 is mounted on the lower end of mounting bracket 4 627; drive component 12 629 is a cylinder, linear motor or electric push rod, mounted on mounting bracket 3 623, and the drive end of drive component 12 629 is movably connected to mounting bracket 4 627, and drive component 12 629 drives mold 2 628 to move up and down.

[0063] The second mold 628 first moves to above the stator core 100 of the first rotating mechanism 41, and then the second mold 628 moves down and presses on the stator core 100, thereby driving the stator core 100 to move from the first rotating mechanism 41 to the bottom mold mechanism 61.

[0064] The lower end of the mounting bracket 627 is provided with a positioning rod 6271. The positioning rod 6271 is movably inserted into the coil slot 104 inside the stator core 100, thereby ensuring that the stator core 100 will not rotate when it moves on the worktable 11.

[0065] The pressing mechanism 2 63 includes: a driving component 13 631, which is a hydraulic cylinder, a pneumatic cylinder, or an electric push rod, and is mounted on the support frame 14; a pressing mold 3 632, which is mounted on the driving end of the driving component 13 631. The pressing mold 3 632 has several notches 2 633 circumferentially arranged on its edge, and a receiving groove 634 is provided at the lower end of the pressing mold 3 632. The receiving groove 634 is used to receive the lower part of the mounting frame 3 623 of the material transfer mechanism 62. When the pressing mold 3 632 presses down on the stator core 100, the pressing mold 2 628 is inserted into the stator core 100, and the lower part of the mounting frame 4 627 (located below the pressing mold 3 632) used to connect with the pressing mold 2 628 is placed in the receiving groove 634 and can also press against the stator core 100 to hold the stator core 100.

[0066] The positioning mechanism 64 includes at least: a driving component 641, which is a cylinder, a linear motor, or an electric push rod, and is mounted on a mounting bracket 821 below the worktable 11; a positioning mold 642, which is mounted on the driving end of the driving component 641, and the edge of the positioning mold 642 has several circumferentially distributed positioning parts 6421, the positioning parts 6421 being movably placed in the coil slot 104 of the stator core 100, and the upper end of the positioning mold 642 passing through the through hole 614 in the mold base 612 and inserted into the stator core 100.

[0067] The positioning mechanism 64 further includes: a slide rail 11 643, which is vertically mounted on the mounting bracket 6 821 below the worktable 11, and a slider 11 644 is slidably mounted on the slide rail 11 643; a mounting bracket 5 645, which is mounted on the slider 11 644, and the driving end of the driving component 14 641 is movably connected to the mounting bracket 5 645. In this design, the two slide rails 11 643 are respectively set on both sides of the mounting bracket 6 821, and the left and right ends of the mounting bracket 5 645 are respectively connected to the sliders 11 644 on both sides; a rotating component 65, which is mounted on the mounting bracket 5 645, and the rotating component 65 is movably connected to the positioning mold 642; and a driving component 15 646, which is a cylinder or electric push rod, which is mounted below the worktable 11, and the driving end of the driving component 15 646 is movably connected to the driving component 14 641.

[0069] After the fastener pressing device 7 presses the fastener 101 onto the left and right sides of the stator core 100, the driving component 15 646 lifts the entire positioning mechanism 64 (driving component 14 641, positioning mold 642, mounting bracket 5 645, and rotating assembly 65), thereby causing the positioning mold 642 to lift the stator core 100, separating the lower end of the stator core 100 from the mold base 612. Then, the rotating assembly 65 rotates the stator core 100 by an angle (e.g., 45 degrees), and then lowers the stator core 100. The fastener pressing device 7 then presses the fastener 101 onto the front and rear sides of the stator core 100, thereby allowing the stator core 100 to... The wall can be pressed in a circumferentially evenly distributed manner by multiple fasteners 101, which ensures the structural stability of the stator core 100. Since the lower end of the fastener 101 will protrude from the lower end of the stator core 100 after being bent and pressed in, that is, placed in the notch 613, the stator core 100 needs to be lifted by the drive component 646. When the fastener pressing device 7 presses the fastener 101 on the front and rear sides of the stator core 100, the die 632 and the die base 612 can further press the upper and lower ends of the fasteners 101 on the left and right sides of the stator core 100 into the upper and lower ends of the stator core 100, so as to prevent the ends of the fasteners 101 from lifting up.

[0070] The fastener pressing device 7 includes two sets of fastener pressing mechanisms 70, which are arranged opposite to each other on the worktables 11 on the left and right sides of the material taking and pressing device 6, for pressing the fasteners 101 on the left and right sides onto the stator core 100 inside the material taking and pressing device 6 at the same time.

[0071] The fastener pressing mechanism 70 includes: a driving component 71, which is a cylinder, an electric push rod, or a linear motor, and is mounted on the worktable 11; a pressing mold assembly 72, which is mounted on the driving end of the driving component 71, and the pressing mold assembly 72 is provided with a pressing groove 721; a clearance opening 16 is provided on the worktable 11, and the clearance opening 16 communicates with the notch 613 of the mold base 612 of the material handling and pressing device 6; the lower end of the pressing mold assembly 72 is slidably placed in the clearance opening 16 and the notch 613, and the upper end of the pressing mold assembly 72 is slidably placed in the notch 633.

[0072] The molding assembly 72 includes: a molding die 73, which is mounted on the driving end of the driving member 71. A protrusion 731 is provided on the lower side of the front end of the molding die 73. The protrusion 731 is provided with a positioning groove 732. The protrusion 731 is slidably placed in the relief opening 16 and extends into the notch 613. A pressing block 74 is slidably disposed on the molding die 73. The lower end of the pressing block 74 cooperates with the upper end of the protrusion 731 and the front end of the molding die 73 to form a pressing groove 721. The front end of the pressing block 74 is provided with a positioning groove 741. A lower pressing member 75 is hinged to the pressing block 74. The end of the lower pressing member 75 is movably placed above the positioning groove 732 for pressing the fastener 101 against the molding die 73. The lower edge of the lower pressing member 75 has a guide surface 751. The pressing block 74 and the lower pressing member 75 can be movably placed in the notch 633.

[0073] The worktable 11 is provided with a slide rail 12 76, and a slider 12 761 is slidably arranged on the slide rail 12 76. The slider 12 761 is movably connected to the drive end of the drive component 17 71 and the mold assembly 72.

[0074] The fastener feeding device 8 includes: a material bin 81, which is installed on the frame 1 and is used to store the rolled strip material, i.e., the raw material of the uncut fastener 101; at least one bending feeding mechanism 82, which is installed at the lower end of the worktable 11 and is used to shape the rolled strip material into a strip material and transport the bent and shaped strip material to the set cutting position; at least one cutting feeding mechanism 83, which is installed on the worktable 11 and is used to cut the shaped strip material into fasteners 101; this design uses two bending feeding mechanisms 82 and two cutting feeding mechanisms 83, with one bending feeding mechanism 82 and one cutting feeding mechanism 83 working together to feed one fastener pressing device 7;

[0075] The cutting and feeding mechanism 83 includes: a fixed blade holder 831, which is mounted on the worktable 11 and has a cutting opening 8311; a movable blade 832, which is slidably mounted on the fixed blade holder 831 and has a positioning groove 8321 at its front end; a driving component 833, which is a cylinder or electric push rod, mounted on the worktable 11 and has its driving end movably connected to the movable blade 832; and a stop feeding assembly, which is mounted on the side of the fixed blade holder 831 and has a limiting part 8361 at its front end on the connecting plate 836 of the stop feeding assembly. The limiting part 8361 and the movable blade 832 are located on both sides of the fastener 101 extending out of the cutting opening 8311.

[0076] The gear feeding assembly includes: a power guide rail 834, which is mounted on the worktable 11; a drive component 22 835, which is a cylinder or a linear motor, which is mounted on the power guide rail 834; a connecting plate 836, which is mounted on the drive end of the drive component 22 835, and the front end of the connecting plate 836 has a limiting part 8361; and a gripper cylinder 837, which is mounted on the connecting plate 836, and the gripper 8371 of the gripper cylinder 837 is located beside the limiting part 8361.

[0077] The moving blade 832 is driven by the drive component 833 to move on the fixed blade holder 831, and the cutting operation is achieved by cooperating with the cutting opening 8311 through the positioning groove 8321. The limiting part 8361 prevents the driving component 833 from driving the moving blade 832 with excessive force, which could damage the gripper cylinder 837.
