Description

Technical Field

[0001] This utility model relates to the technical field of clamping machines, and specifically to a magnetic clamping machine. Background Technology

[0002] In the field of automated material handling, traditional industrial production lines generally use manual or semi-automated equipment to sort and transfer stacked workpieces. This type of operation usually relies on forklifts and simple lifting platforms to initially separate the stacked workpieces, and then manual use of suction cups or electromagnets to pick up individual pieces. Finally, the workpieces are placed on a conveyor belt of fixed width for transfer. However, this operation mode has significant drawbacks: the efficiency of manual sorting is limited by the operator's skill level, and fatigue can easily cause fluctuations in the sorting cycle during continuous operation. Traditional electromagnetic chucks pose a risk of magnetic residue, which may cause the workpieces to stick or scratch the surface. Traditional devices have difficulty accurately identifying the layer interface, often resulting in production interruptions due to the simultaneous grabbing of multiple layers of workpieces. In addition, traditional conveyor mechanisms mostly use fixed guide rail designs. When product specifications change, the conveyor width needs to be adjusted manually by adjusting the lead screw or changing the fixture, which seriously restricts the flexibility of the production line. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a magnetic clamping machine. This invention adopts a deep collaborative mechanism of lifting and separating plate mechanism and translation clamping plate mechanism. The lifting component uses a brake motor to drive a ball screw to control the lifting of the base plate. In conjunction with the first width-adjusting ball screw driven by a stepper motor in the sorting component, it drives the limiting strip to form a clamping interface. When the push plate cylinder drives the cylinder push head to perform precise clamping, only the workpieces below the second layer are limited and fixed, while the first layer of workpieces is gripped by the clamping component without damage. By eliminating manual intervention, sorting efficiency is improved while the damage rate of workpieces is reduced. The feeding mechanism uses a width-adjusting transmission component. The width-adjusting motor drives the second width-adjusting ball screw to rotate via a toothed belt, causing the movable track support plate to slide along the fixed rigid shaft of the transmission, realizing dynamic adjustment of the distance between the moving guide rail and the fixed guide rail. When the second transmission motor starts, the second belt and the first belt of the fixed transmission component form a synchronous operation system through the connecting pulley, which expands the range of widths of workpieces to be processed and improves adaptability compared to traditional fixed guide rails.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A magnetic clamping machine includes a frame, within which a lifting and separating mechanism is provided for separating stacked workpieces to be processed. A translation clamping mechanism is provided on the lifting and separating mechanism for gripping the workpieces to be processed. A feeding mechanism is provided on one side of the lifting and separating mechanism for transferring the workpieces to be processed to the next workstation in conjunction with the translation clamping mechanism. The lifting and separating mechanism includes a pallet base plate within the frame, a lifting assembly on the pallet base plate, and a sorting assembly on the lifting assembly.

The clamping plate is used to install the push plate cylinder.

[0008] The translation chuck mechanism includes a mounting frame on the top of the frame, a translation drive assembly on the mounting frame, and a clamping assembly located under the mounting frame via a second slide rail assembly. The translation drive assembly and the clamping assembly are connected via a translation crossbar. The mounting frame supports and mounts the translation drive assembly and the clamping assembly. The translation drive assembly drives the clamping assembly to move laterally. The clamping assembly is used to grab the workpiece to be processed from the lifting and separating plate mechanism station and release the workpiece to be processed from the feeding mechanism station.

[0009] The translation drive assembly includes a translation motor located at one end of the mounting frame, a drive wheel located at the output end of the translation motor, a synchronous pulley located at the other end of the mounting frame, and a synchronous belt sleeved on the drive wheel.

The translation motor is used to output torque through the drive wheel. The drive wheel is used to transmit the torque to the translation horizontal plate through the synchronous belt. The synchronous pulley is used to rotate in coordination with the synchronous belt.

[0010] The clamping assembly includes a vertical translating plate located below the horizontal translating plate, a slide cylinder located on one side of the vertical translating plate, a clamping mounting plate located at the output end of the slide cylinder, a clamping cylinder located at each end of the clamping mounting plate, and a clamping head located at the output end of the clamping cylinder. The other side of the vertical translating plate is connected to a second slide rail assembly. The slide cylinder is used to drive the clamping mounting plate to adjust its vertical displacement. The clamping mounting plate is used to support and mount the clamping cylinder. The clamping cylinder is used to drive the clamping head to open and close. The clamping head is used to directly contact the workpiece to be processed.

[0011] The feeding mechanism includes a conveying base plate disposed within the frame, a feeding support assembly disposed on the conveying base plate, a fixed transmission assembly disposed on the feeding support assembly, and a width-adjusting transmission assembly disposed on one side of the fixed transmission assembly. The conveying base plate is used to support and install the feeding support assembly, and the feeding support assembly is used to install the fixed transmission assembly and the width-adjusting transmission assembly.

[0012] The feeding support assembly includes a transmission support plate disposed on the transmission base plate, a fixed support plate disposed on one side of the transmission support plate via at least one transmission fixed rigid shaft, at least one second width-adjusting ball screw disposed on one side of the transmission fixed rigid shaft, and a width-adjusting screw nut threadedly connected to the second width-adjusting ball screw. The transmission support plate is used to cooperate with the fixed support plate to install the transmission fixed rigid shaft and the second width-adjusting ball screw. The second width-adjusting ball screw is used to convert the rotational motion into axial linear motion of the width-adjusting screw nut.

[0013] The fixed transmission assembly includes a fixed guide rail mounted on the fixed transmission shaft via a guide rail mounting base, a first transmission motor located at one end of the fixed guide rail, and a first belt located at the output end of the first transmission motor and connected by at least two connecting pulleys.

[0014] The width-adjusting transmission assembly includes a width-adjusting motor mounted on one side of the fixed support plate, a drive wheel mounted at the output end of the width-adjusting motor, a driven wheel mounted at one end of the second width-adjusting ball screw, a movable track support plate passing through the nut of the width-adjusting screw, a movable guide rail mounted on the movable track support plate, a second transmission motor mounted at one end of the movable guide rail, and a second belt mounted at the output end of the second transmission motor and connected by at least two connecting pulleys. The drive wheel and the driven wheel are connected by a toothed belt. The movable track support plate is slidably connected to the fixed transmission shaft by a flange bearing. The width-adjusting motor drives the toothed belt to rotate via the drive wheel. The driven wheel cooperates with the toothed belt to drive the second width-adjusting ball screw to rotate. The movable track support plate is used to mount the movable guide rail. The movable guide rail is used to support and mount the second transmission motor. The second transmission motor drives the second belt to rotate along one side of the movable guide rail via the connecting pulleys. The second belt cooperates with the first belt to synchronously move the workpiece to be processed.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The brake motor of the lifting assembly drives the ball screw to rotate through the first transmission belt, so that the lifting base plate lifts the workpiece to be processed with a precision of 0.01mm. In conjunction with the first width-adjusting ball screw driven by the stepper motor in the sorting assembly, the limiting strip slides along the slide groove to form a wedge-shaped clamping interface for the stacked workpieces to be processed. When the push plate cylinder drives the cylinder push head to extend, only the second layer and below of workpieces to be processed are pressed by the closed-loop structure formed by the limiting strip and the side baffle, while the first layer of workpieces to be processed is gripped non-destructively by the clamping head of the translation chuck mechanism through the clamping cylinder. The lifting height of the lifting assembly and the pressing action of the sorting assembly create a time-space misalignment, which completely solves the problem of production interruption caused by the simultaneous gripping of multiple layers of workpieces to be processed in traditional equipment.

[0017] 2. The width-adjusting transmission component of the feeding mechanism drives the second width-adjusting ball screw to rotate via a toothed belt through a width-adjusting motor. This causes the width-adjusting screw nut to drive the movable track support plate to slide along the fixed transmission shaft, dynamically adjusting the distance between the moving guide rail and the fixed guide rail. When the second transmission motor starts, the second belt and the first belt of the fixed transmission component operate synchronously through the connecting pulley, forming a width-adjustable conveying channel for the workpiece to be processed, thus expanding the compatible width range of the equipment to 2-3 times that of the original equipment.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figure 1-9As shown, this utility model relates to a magnetic clamping machine, including a frame 1, within which a lifting and separating mechanism 2 is provided for separating stacked workpieces to be processed; a translation clamping mechanism 3 is provided on the lifting and separating mechanism 2 for cooperating with the lifting and separating mechanism 2 to grip the workpieces to be processed; a feeding mechanism 4 is provided on one side of the lifting and separating mechanism 2 for cooperating with the translation clamping mechanism 3 to transfer the workpieces to be processed to the next workstation; the lifting and separating mechanism... The 2 includes a pallet base plate 20 disposed within the frame 1, a lifting assembly 21 disposed on the pallet base plate 20, and a sorting assembly 22 disposed on the lifting assembly 21. The lifting assembly 21 is used to lift the workpieces to be separated to the sorting assembly 22 station. The sorting assembly 22 is used to cooperate with the lifting assembly 21 to separate the workpieces one by one. The frame 1 provides a stable mounting platform for other mechanisms. The lifting and separating mechanism 2 is responsible for separating the stacked workpieces. The lifting assembly 21 inside it is controlled by a brake. Motor 217 drives ball screw 215 to rotate, which in turn lifts the workpiece to be processed to the sorting component 22 station, supported by lifting shaft 211 and lifting base plate 212. The sorting component 22, with its pusher cylinder 222, limit bar 226, and other components, separates the workpieces one by one, achieving orderly disassembly of the stacked workpieces. Translation clamping mechanism 3 spans above the lifting and separating mechanism 2 and the feeding mechanism 4. Translation motor 310 of translation drive component 31 drives clamping component 32 laterally via drive wheel 311 and synchronous belt 313. The sliding table cylinder 322, clamping cylinder 324 and other components of the clamping assembly 32 work together to grab the workpiece to be processed from the lifting and separating mechanism 2 and release it at the feeding mechanism 4, thus completing the transfer of the workpiece to be processed. The feeding mechanism 4 can discharge materials back and forth through the discharge ports on both sides of the frame 1. The lifting and separating mechanism 2 separates and stacks the workpiece to be processed, the lateral clamping mechanism 3 transfers the workpiece to be processed, and the feeding mechanism 4 conveys the workpiece to be processed, together completing the processing of the workpiece to be processed by the magnetic clamping machine.

[0031] like Figure 2-5As shown, the lifting assembly 21 includes a lifting rigid shaft 211 slidably connected to the pallet base plate 20 via a first bushing 210, a lifting base plate 212 located at one end of the lifting rigid shaft 211, a guide fixing plate 213 located at the other end of the lifting rigid shaft 211, a ball screw 215 threaded through the guide fixing plate 213 and connected via a ball screw nut 214, and a brake motor 217 connected to one side of the ball screw 215 via a first transmission belt 216. One end of the ball screw 215 is connected via a first... The bearing seat 218 is limitedly connected to the pallet base plate 20. The lifting rigid shaft 211 supports the lifting base plate 212, which is used to place the workpiece to be processed. The guide fixing plate 213 cooperates with the ball screw 215 to realize the lifting action of the lifting base plate 212. The ball screw 215 cooperates with the brake motor 217 to rotate. The brake motor 217 transmits the rotational torque to the ball screw 215 through a transmission belt. The lifting base plate 212 is also provided with at least two sliding grooves 2120. The brake motor 217 is connected to a... The motor plate is fixedly connected to the tray base plate 20. The output end of the brake motor 217 is equipped with a brake drive wheel 2170. A screw driven wheel 2150 is rigidly connected to the ball screw 215. The brake motor 217 drives the brake drive wheel 2170 to rotate the first transmission belt 216. The first transmission belt 216 drives the screw driven wheel 2150 to rotate synchronously with the ball screw 215. The rotational motion of the ball screw 215 is converted into the axial linear motion of the ball screw nut 214 through the ball screw nut 214. Nut 214 drives the fixed guide plate 213 to rise and fall synchronously. The guide plate 213 drives the lifting shaft 211 to slide along the first bushing 210. The lifting shaft 211 drives the lifting base plate 212 to rise and fall synchronously. When a lifting command is received, the brake motor 217 rotates in the forward direction, driving the ball screw nut 214 to rise, thereby lifting the workpiece to be processed to the sorting component 22 station of the lifting base plate 212. Conversely, when reloading is required, the brake motor 217 rotates in the reverse direction, causing the lifting base plate 212 to move down back to its original position.

[0032] like Figure 2-5As shown, the sorting assembly 22 includes a clamping plate 220 disposed on one side of the lifting assembly 21, a side baffle 221 disposed on one side of the clamping plate 220, at least one push plate cylinder 222 disposed on one side of the clamping plate 220, a cylinder push head 223 disposed at the output end of the push plate cylinder 222, a slider fixing seat 225 disposed on the tray base plate 20 and slidably connected by at least one first slide rail assembly 224, at least two limiting strips 226 disposed on the slider fixing seat 225, a first width adjusting ball screw 228 disposed below the slider fixing seat 225 and threadedly connected by at least one lead screw nut seat 227, and one of the first width adjusting ball screws 228... The tray has a width-adjusting mounting base 229 and a stepper motor 230 mounted on a motor mounting plate 231. The stepper motor 230 is connected to the first width-adjusting ball screw 228 via a transmission belt 232. The limiting strip 226 is slidably connected to the lifting base plate 212 via a slide groove 2120. The clamping plate 220 is used to mount the push plate cylinder 222. The side baffle 221 is used to limit the workpiece to be processed. The push plate cylinder 222 is used to drive the cylinder push head 223 to extend and retract. The cylinder push head 223 is used to clamp the workpiece to be processed in conjunction with the limiting strip 226. The first width-adjusting ball screw 228 has a first... A bearing 233 connects the first width-adjusting ball screw 228 to the clamping plate 220. The first width-adjusting ball screw 228 is also connected to the width-adjusting mounting base 229 via the first bearing 233. When a separation command is received, the stepper motor 230 drives the first width-adjusting ball screw 228 to rotate via a transmission belt 232. The first width-adjusting ball screw 228 drives the slider fixing base 225 to move linearly along the axial direction via a screw nut seat 227. The slider fixing base 225 drives the limiting strip 226 to move synchronously. When the stepper motor 230 rotates in the forward direction, the screw nut seat 227 drives the slider fixing base 225 to move in the forward direction. As the workpiece to be processed moves to one side, the limiting strip 226 moves synchronously and contacts the workpiece to be processed. However, at this time, the limiting strip 226 does not press the workpiece to be processed. At the same time, the push plate cylinder 222 drives the cylinder push head 223 to extend the clamping plate 220, so that the cylinder push head 223 cooperates with the limiting strip 226 to press the workpieces to be processed below the second layer. Here, the lifting component 21 is used to control the lifting height of the workpiece to be processed to achieve clamping only the workpieces to be processed below the second layer. Then, the translation clamping mechanism 3 works to clamp the first layer of workpieces to be processed. The first slide rail group 224 consists of at least one guide rail and at least one slider that is slidably connected to the guide rail.

[0033] like Figure 2 , 6As shown in Figure 7, the translation clamping mechanism 3 includes a mounting frame 30 on the top of the frame 1, a translation drive assembly 31 on the mounting frame 30, and a clamping assembly 32 located below the mounting frame 30 via a second slide rail group 320. The translation drive assembly 31 and the clamping assembly 32 are connected via a translation horizontal plate 314. The mounting frame 30 supports the translation drive assembly 31 and the clamping assembly 32. The translation drive assembly 31 drives the clamping assembly 32 to move laterally. The clamping assembly 32 grips the workpiece to be processed from the lifting and separating plate mechanism 2 station to the feeding mechanism 4 station and releases the workpiece. The translation drive assembly 31 is responsible for moving the clamping assembly 32 along the second slide rail group 320, thereby lifting... The translation clamping mechanism 3, whose mounting frame 30 is fixed to the top of the frame 1, provides driving force and supports the operating load of the translation drive assembly 31, while also creating an execution space for the reciprocating motion of the clamping assembly 32. The translation motor 310 in the translation drive assembly 31 converts the rotational torque into the horizontal displacement driving force of the clamping assembly 32 through the power transmission link formed by the drive wheel 311 and the synchronous belt 313. The second slide rail group 320 serves as a guide and support component. The cooperation between the guide rail surface and the translation vertical plate 321 restricts the degree of freedom of movement of the clamping assembly 32 and ensures the stability of the translation process through its low friction characteristics. The second slide rail group 320 consists of at least one guide rail and at least one slider that is slidably connected to the guide rail.

[0034] like Figure 6-7As shown, the translation drive assembly 31 includes a translation motor 310 located at one end of the mounting bracket 30, a drive wheel 311 located at the output end of the translation motor 310, a synchronous pulley 312 located at the other end of the mounting bracket 30, and a synchronous belt 313 sleeved on the drive wheel 311. The other end of the synchronous belt 313 is connected to the synchronous pulley 312. The synchronous belt 313 is fixedly connected to the translation horizontal plate 314 via a pressure plate. The translation motor 310 outputs torque through the drive wheel 311, and the drive wheel 311 transmits the torque to the translation horizontal plate 314 through the synchronous belt 313. The synchronous pulley 312 rotates in coordination with the synchronous belt 313. When a translation command is received, the translation motor 310 of the translation drive assembly 31 starts, and the translation motor 310 transmits the rotational torque to the drive wheel 311 through its output end, causing the drive wheel 311 to rotate. The synchronous belt 313, which is fitted onto the drive wheel 311, is driven by the drive wheel 311 under friction or tooth meshing to form a circular motion. The synchronous wheel 312 connected to the other end of the synchronous belt 313 is passively rotated under the traction of the synchronous belt 313. The synchronous wheel 312 mainly maintains the tension of the synchronous belt 313 and assists in transmission guidance. Since the synchronous belt 313 is rigidly connected to the translation horizontal plate 314 through the pressure plate, the circular motion of the synchronous belt 313 is converted into the unidirectional linear motion of the translation horizontal plate 314. At the same time, the motion trajectory of the translation horizontal plate 314 driving the translation vertical plate 321 is guided and constrained by the second slide rail group 320, so that the translation drive component 31 accurately converts the rotational kinetic energy of the translation motor 310 into the horizontal movement energy of the clamping component 32, and completes the spatial transfer of the workpiece to be processed between the lifting and separating plate mechanism 2 and the feeding mechanism 4.

[0035] like Figure 6-7As shown, the clamping assembly 32 includes a vertical translating plate 321 located below the horizontal translating plate 314, a slide cylinder 322 located on one side of the vertical translating plate 321, a clamping mounting plate 323 located at the output end of the slide cylinder 322, a clamping cylinder 324 located at each end of the clamping mounting plate 323, and a clamping head 325 located at the output end of the clamping cylinder 324. The other side of the vertical translating plate 321 is connected to the second slide rail assembly 320. The slide cylinder 322 is used to drive the clamping mounting plate 323 to adjust its vertical displacement. The clamping mounting plate 323 is used to support... A clamping cylinder 324 is installed to drive the clamping head 325 to open and close, and the clamping head 325 is used to directly contact the workpiece to be processed. After the clamping assembly 32 is accurately transported above the workpiece by the translation drive assembly 31, the translation vertical plate 321, as a connecting carrier, completes the lateral positioning synchronously with the translation horizontal plate 314. At this time, the slide cylinder 322 is activated, and its piston rod pushes the clamping mounting plate 323 to extend downward in the vertical direction. Through a preset stroke, the clamping heads 325 at both ends of the clamping mounting plate 323 are precisely aligned with the first layer of workpiece to be processed. The workpiece is gripped at the workpiece gripping position; when the gripping cylinder 324 receives the gripping command, the two gripping cylinders 324 move synchronously, the pistons contract and drive the gripping heads 325 to move in opposite directions in the horizontal direction, and the first layer of workpiece edges is stably gripped through mechanical limit or force control feedback; during the workpiece transfer stage, the slide cylinder 322 contracts in the opposite direction according to the height of the feeding mechanism 4, driving the gripping mounting plate 323 and the gripped workpiece to be vertically lifted, ensuring that the workpiece to be processed is completely separated from the second layer of workpieces to be processed (the translation chuck mechanism 3 maintains the gripping action); when the translation drive assembly 3 1. After the clamping assembly 32 is conveyed to the top of the feeding mechanism 4, the slide cylinder 322 extends again to adjust the release height, and the piston rod of the clamping cylinder 324 pushes outward to open the clamping head 325. The workpiece to be processed is smoothly transferred to the transmission assembly of the feeding mechanism 4 under the action of gravity, completing a single transfer of the workpiece to be processed. The rigid connection of the translation vertical plate 321 ensures the stability of the action, the vertical adjustment of the slide cylinder 322 adapts to different thicknesses of the workpiece to be processed, and the synchronous opening and closing of the clamping cylinder 324 ensures the reliability of the gripping. All components work together to realize the spatial transfer and precise release of the workpiece to be processed.

[0036] Furthermore, when the clamping assembly 32 completes the clamping of the first layer of workpieces to be processed, the sliding table cylinder 322 retracts upward, causing the clamping mounting plate 323 to rise, so that the first layer of workpieces to be processed is separated from the second layer of workpieces to be processed. Then, the push plate cylinder 222 retracts, causing the cylinder push head 223 to disengage from the second layer of workpieces to be processed. At this time, the lifting assembly 21 drives the lifting base plate 212 to lift one position through the brake motor 217, and the second layer of workpieces to be processed becomes the first layer of workpieces to be processed. After that, the push plate cylinder 222 extends again, causing the cylinder push head 223 to extend and press the second layer of workpieces to be processed at this time, waiting for the clamping assembly 32 of the translation chuck mechanism 3 to clamp and pick up the workpieces again, and so on in a cycle.

[0037] like Figure 2-3 As shown in Figures 8-9, the feeding mechanism 4 includes a conveying base plate 40 disposed within the frame 1, a feeding support assembly 41 disposed on the conveying base plate 40, a fixed transmission assembly 42 disposed on the feeding support assembly 41, and a width-adjusting transmission assembly 43 disposed on one side of the fixed transmission assembly 42. The conveying base plate 40 is used to support and install the feeding support assembly 41, and the feeding support assembly 41 is used to install the fixed transmission assembly 42 and the width-adjusting transmission assembly 43. The conveying base plate 40 is the mounting base of the feeding mechanism 4, providing stability for each component. The second width-adjusting ball screw 413 in the feeding support assembly 41 starts the adjustment program according to the width parameter of the workpiece to be processed. The width-adjusting motor 430 drives the second width-adjusting ball screw 413 to rotate through the transmission system of the drive wheel 431 and the toothed belt 437, causing the width-adjusting screw nut 414 to generate linear displacement along the axial direction, thereby driving the movable track support plate 433 to slide along the conveying fixed hard shaft 411, adjusting the distance between the moving guide rail 434 and the fixed guide rail 421 until it matches the width of the workpiece to be processed; when the distance is adjusted... After completion, the workpiece to be processed is released by the translation chuck mechanism 3 onto the conveying platform of the feeding mechanism 4, which is composed of the fixed transmission component 42 and the width-adjusting transmission component 43. When the workpiece to be processed is placed on the bearing surface formed by the first belt 424 and the second belt 436, the first transmission motor 422 of the fixed transmission component 42 and the second transmission motor 435 of the width-adjusting transmission component 43 start synchronously. The first transmission motor 422 drives the first belt 424 to circulate along the surface of the fixed guide rail 421 through the connecting pulley 423, while the second transmission motor 435 drives the second belt 436 to rotate synchronously along the surface of the moving guide rail 434 through the same transmission method. The two belts drive the workpiece to be processed to move smoothly in the discharge direction through surface friction or tooth meshing. When the workpiece to be processed reaches the preset position of the discharge port, the motor stops running and the belt stops driving, completing the single conveying of the workpiece to be processed. The width-adjusting transmission component 43 is dynamically adjusted to adapt to different specifications of workpieces to be processed, and the synchronous drive of the fixed transmission component 42 and the width-adjusting transmission component 43 is used to achieve the smooth discharge of the workpiece to be processed.

The transmission support plate 410 is used to cooperate with the fixed support plate 412 to install the transmission fixed rigid shaft 411 and the second width-adjusting ball screw 413. The second width-adjusting ball screw 413 is used to convert the rotational motion into axial linear motion on the width-adjusting screw nut 414.

The fixed guide rail 421 is used to support and mount the first transmission motor 422. The first transmission motor 422 is used to drive the first belt 424 to rotate along one side of the fixed guide rail 421 via the connecting pulleys 423. The first belt 424 is used to move the workpiece to be processed.

[0040] like Figure 2-3 As shown in Figures 8-9, the width adjustment transmission assembly 43 includes a width adjustment motor 430 disposed on one side of the fixed support plate 412, a drive wheel 431 disposed at the output end of the width adjustment motor 430, a driven wheel 432 disposed at one end of the second width adjustment ball screw 413, a movable track support plate 433 passing through the width adjustment screw nut 414, a movable guide rail 434 disposed on the movable track support plate 433, a second transmission motor 435 disposed at one end of the movable guide rail 434, and a second belt 436 disposed at the output end of the second transmission motor 435 and connected to it via at least two connecting pulleys 423. The drive wheel 431 and the driven wheel 432 are transmitted through a toothed belt 437. The movable track support plate 433 is slidably connected to the fixed conveyor shaft 411 via a flange bearing 438. The width-adjusting motor 430 drives the toothed belt 437 to rotate via the drive wheel 431. The driven wheel 432 cooperates with the toothed belt 437 to drive the second width-adjusting ball screw 413 to rotate. The movable track support plate 433 is used to install the movable guide rail 434. The movable guide rail 434 is used to support and install the second conveyor motor 435. The second conveyor motor 435 drives the second belt 436 to rotate along one side of the movable guide rail 434 via the connecting pulley 423. The second belt 436 cooperates with the first belt 424 to synchronously drive the workpiece to be processed to move.

[0041] The workflow is as follows: Frame 1 serves as the basic framework, transferring the equipment load to the support surface to ensure overall stability and providing a stable mounting platform for the lifting and separating mechanism 2, the translation clamping mechanism 3, and the feeding mechanism 4. When the equipment starts, the lifting and separating mechanism 2 begins operation. Its internal lifting component 21 drives the ball screw 215 to rotate via the brake motor 217. The rotational motion of the ball screw 215 is converted into axial linear motion via the ball screw nut 214, driving the guide fixing plate 213 and the connected lifting rigid shaft 211 to slide upward along the first bushing 210, thereby lifting the stacked workpieces to be processed to the sorting component 22 station via the lifting base plate 212. At this time, the stepper motor 230 of the sorting component 22 drives the first... The width-adjusting ball screw 228 rotates, and the first width-adjusting ball screw 228 drives the slider fixing seat 225 to move axially along the first slide rail group 224 through the screw nut seat 227, adjusting the spacing of the limit strips 226 to adapt to the width of the workpiece to be processed. When the limit strips 226 contact the workpiece to be processed, the push plate cylinder 222 drives the cylinder push head 223 to extend the clamping plate 220, and cooperates with the limit strips 226 to clamp the workpieces below the second layer. Then, the translation motor 310 of the translation clamping mechanism 3 starts, and the rotational torque is converted into the horizontal displacement of the translation horizontal plate 314 through the transmission link formed by the drive wheel 311 and the synchronous belt 313. The translation horizontal plate 314 drives the translation vertical plate 321 to move along the second slide rail group 320 to the top of the lifting and separating plate mechanism 2, at which time the clamping is performed. The slide cylinder 322 of component 32 drives the clamping mounting plate 323 to descend vertically. The piston rod of the clamping cylinder 324 retracts, causing the clamping head 325 to clamp the edge of the first layer of workpieces to be processed. The slide cylinder 322 then lifts up, separating the workpieces to be processed from the second layer. The translation motor 310 rotates in the opposite direction, pulling the translation plate 314 to move above the feeding mechanism 4 via the synchronous belt 313. The slide cylinder 322 then actuates again to adjust the release height. The piston rod of the clamping cylinder 324 pushes outward, causing the clamping head 325 to open. The workpieces to be processed are released onto the conveying platform formed by the fixed transmission component 42 and the width adjustment transmission component 43. In advance, the width adjustment motor 430 of the feeding mechanism 4 drives the second width adjustment ball screw 413 to rotate via the toothed belt 437. The width adjustment ball screw nut 414... The movable track support plate 433 slides along the conveyor fixed rigid shaft 411, and the distance between the moving guide rail 434 and the fixed guide rail 421 is adjusted to match the width of the workpiece to be processed. The first conveyor motor 422 and the second conveyor motor 435 start synchronously, and drive the first belt 424 and the second belt 436 to rotate in a cycle through the connecting pulley 423. The two belts drive the workpiece to be processed to move smoothly towards the discharge port through friction. When the workpiece to be processed reaches the preset position, the conveyor motor stops, completing a single workpiece processing cycle. Through the precise lifting of the lifting component 21, the layered pressing of the sorting component 22, the precise transfer of the translation clamping mechanism 3, and the adaptive conveying of the feeding mechanism 4, the magnetic clamping machine realizes the automated disassembly and transfer of the stacked workpieces to be processed.
