Description

Technical Field

[0001] The present invention relates to a continuous feeding device, and particularly to a continuous feeding device for yokes in the processing of electromagnetic brakes. Background Art

[0002] At present, in the field of continuous feeding for the machining of yoke slots of electromagnetic brakes, common feeding methods mainly rely on feeding tables or transplanting robotic arms. The feeding table usually requires manual placement of workpieces at designated positions, and then subsequent mechanisms perform the material taking operation. Although this method realizes the feeding function to a certain extent, for multi-layer stacked workpieces, there is a lack of effective stratification means. Often, manual separation of the workpieces layer by layer is required before feeding, resulting in low efficiency and high labor intensity. Transplanting robotic arms are widely used in automated feeding. When facing multi-layer stacked workpieces, in order to improve the grasping efficiency, some devices use multi-jaw manipulators. However, such multi-jaw manipulators have obvious defects. Their jaw positions are fixed, the structure is complex, and they need to be used in conjunction with specific equipment, with extremely low flexibility. Once production requirements change, such as changes in workpiece size and shape, the entire equipment may require large-scale adjustment and modification, increasing production costs and maintenance difficulties. In addition, existing feeding equipment generally requires tooling for precise positioning and placement of workpieces. However, in the actual production process, the workpieces on the tooling are often stacked in multiple layers, and existing equipment cannot effectively stratify and quickly remove multiple materials from the tooling. This leads to frequent adjustment and repositioning of the tooling during the feeding process. Summary of the Invention

[0006] The layered chain plates include: a chain plate box, which is fixedly installed on one side of the equipment frame, and is equipped with a partition support chain. The partition support chain is composed of multiple chain plates, one end of which is connected to one side of the destacking push plate and is pulled out from the chain plate box as the destacking push plate moves. Both ends of the single-section chain plate are respectively provided with extension protrusions and overlapping grooves. When the partition support chain is flattened, the extension protrusion on the chain plate will be stuck in the overlapping groove of the chain plate of the previous section; Spring 2 is arranged in the chain plate box, and its two ends are respectively connected to the end of the partition support chain and the chain plate box, so as to put the reset-moved partition drag chain into the chain plate box.

[0007] Furthermore, the lifting and transferring platform includes: a bottom frame, which is installed on the lower right part of the main body support, and a lifting cylinder, which is vertically installed on the bottom frame, and is provided with multiple; a transferring platform, which is fixedly arranged between the top ends of the movable rods of the lifting cylinders, and is raised and lowered as the movable rods of the lifting cylinders are extended and retracted.

[0011] Further, it further includes: a fixed seat, installed on the C-shaped frame near the one-way rotating plate, with a sliding block installed therein in a left-right sliding manner; a limiting block, connected to the sliding block inside the fixed seat, and located on the rotation path of the one-way rotating plate; an adjusting rod, passing through the fixed seat, provided with threads thereon, one end of the adjusting rod passing through the inner side of the sliding block and rotatably connected to the C-shaped frame, the sliding block being screwed to the adjusting rod. When the adjusting rod rotates, the slider will adjust its position left and right inside the fixed seat, thereby driving the limiting block to displace, so as to adjust the spacing distance between the limiting block and the one-way rotating plate.

In this way, it can be specifically set according to workpieces of different sizes and heights, effectively avoiding problems such as material jamming, failure of layered blocking, and inability to pass smoothly caused by the mismatch between the workpiece and the entrance and exit height, and improving the compatibility and versatility of the equipment for different workpieces.

[0018] 5. By arranging a processing component on the mounting seat at the discharging end of the material conveying line, the present invention synchronizes the material conveying and processing actions, reduces the idle waiting time, realizes seamless connection between "material conveying - processing", and greatly shortens the production beat time.

[0031] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited.

[0032] Embodiment 1

[0033] A magnetic yoke continuous feeding device for electromagnetic brake processing, as Figures 1 - 11 shown, includes an equipment frame 1, the top of which is provided with an integrated control panel, and the panel is linked with the control components in the device through cables to realize the start-stop of the whole machine and the adjustment of operation parameters. The removable guard plate 2 is installed on the front and back sides of the equipment frame 1 through a slide rail and a locking mechanism. The inner side of the removable guard plate 2 is covered with a shock-absorbing sealing strip. This structure not only supports quick disassembly for maintaining the internal components of the equipment frame 1, but also can effectively reduce the vibration transmission between the removable guard plate 2 and the equipment frame 1 and prevent foreign matters such as dust from entering the equipment interior; the main body support 3 is cast from high-strength aluminum alloy material and is symmetrically installed at the lower part inside the equipment frame 1 front and back. One end of it extends out of the equipment frame 1 to the left from inside the equipment frame 1. The main body support 3 is rigidly connected to the internal cross beam of the equipment frame 1 through bolts. Through reasonable layout of the two main body supports 3, a transmission path is formed at its upper part; the conveyor chain 31 adopts a double-row roller chain structure and is arranged in the upper part inside the two main body supports 3 along the transmission path. The conveyor chain 31 is linked with a servo motor through a reduction gear set, and it is used to transport the tooling 101. Multiple groups of magnetic yoke workpieces 100 are densely and neatly stacked on the top of the tooling 101, and the layer stacking distance is controlled within 5 mm. While increasing the loading quantity of the tooling 101, the interval between the layer stacks is shortened as much as possible. The tooling 101 advances uniformly along the transmission path with the conveyor chain 31; lifting feeding platforms are arranged at the right ends of the two main body supports 3, and the two lifting feeding platforms are on the same front-back line;

[0034] As Figure 2 and Figure 3 shown, the lifting and feeding table includes: a bottom frame 32 rigidly connected to the lower right part of the main body bracket 3 by high-strength bolts, with a cylinder mounting plate welded inside for fixing four groups of lifting cylinders 33. The lifting cylinders 33 are distributed in a rectangular array to balance the force on the feeding platform 34; the bottom of the feeding platform 34 is thread-locked to the top end of the piston rod of the lifting cylinder 33 through a flange, and a transfer pulley 35 is provided inside the feeding platform 34; the belt surface height of the transfer pulley 35 is slightly higher than the bearing surface of the feeding platform 34, and auxiliary guiding components can be arranged at the four corners of the feeding platform 34 to cooperate with the bottom frame 32 to ensure no skew during the lifting process. When the conveying chain 31 transports the tooling 101 to directly above the feeding platform 34, two lifting cylinders 33 synchronously lift the feeding platform 34. The transfer pulley 35 is driven by a built-in reduction motor of the feeding platform 34, and a directional frictional force is generated between its surface and the bottom of the tooling 101. When the transfer pulleys 35 of the front and rear two lifting and feeding tables are started simultaneously, the tooling 101 slides forward under the action of the conveying force to the feeding platform 34 of another transmission path.

[0035] Specifically, the conveying chains 31 on the front and rear two main body brackets 3 are respectively used for the feeding and discharging transmission of the tooling 101. The tooling 101 stacked with workpieces 100 is fed into the equipment frame 1 from right to left on the rear conveying chain 31; initially, the movable rod of the lifting cylinder 33 is in the retracted state, and the feeding platform 34 is located in the area between the double-row conveying chains 31. When the tooling 101 carrying the yoke workpiece 100 reaches the end of the rear conveying chain 31, it is located in the upper space of the rear lifting and feeding table. The two lifting and feeding tables are lifted synchronously, and the rear lifting and feeding table lifts the tooling 101 to the upper limit position. Subsequently, the tooling 101 is transferred to the front lifting and feeding table. After the lifting and feeding table is reset, the double-line handover and material transfer of the tooling 101 are completed, and the tooling 101 is sent out of the device from right to left through the front conveying chain 31, thus avoiding manual intervention and improving the multi-process connection efficiency, realizing the full-automatic cyclic feeding of the yoke workpiece 100 between the double transmission paths, and greatly reducing the risk of equipment jamming;

[0036] As Figure 2 、 Figure 4 and Figure 5As shown in the figure, a lifting cylinder 4 is vertically installed at the top of the front side of the equipment frame 1. Its driving rod penetrates through the top plate of the equipment frame 1 and extends to the inside. The end of the driving rod is rigidly connected with a main support plate 41. Driven by the lifting cylinder 4, the main support plate 41 vertically lifts and lowers along the inner cavity of the equipment frame 1. A sliding table 42 is installed at the bottom of the main support plate 41, and the right part of which is located in the space directly above the front lifting and feeding table. The main support plate 41 is symmetrically arranged front and back and is laterally provided with a driving cylinder 43. Linear guide pairs are arranged in parallel on the front and back sides of the top of the sliding table 42. A palletizing arm is arranged between the linear guide pairs. One side of the palletizing arm is connected with the driving rod of the driving cylinder 43. Driven by the driving rod, the palletizing arm moves left and right along the guide rail of the linear guide pair. A U-shaped frame 5 is arranged on the lower end surface of the sliding table 42, and its open end faces the left side. A one-way rotating plate 52 is installed through a pin shaft. The one-way rotating plate 52 naturally hangs down under the action of gravity, so that the U-shaped frame 5 forms a closed structure under normal conditions, and only allows the material to be pushed out from the U-shaped frame 5. A feeding line is installed on the left side inside the equipment frame 1. The feeding port end of the feeding line is flush with the apex of the lifting track of the front lifting and feeding table, and is used to receive the material pushed out from the U-shaped frame 5 and transport it to the next process;

[0037] When the tooling 101 carrying the workpiece 100 is lifted and transferred from the rear lifting and feeding table to the front lifting and feeding table, the tooling 101 and the feeding end of the feeding line are on the same horizontal line left and right. At this time, the bottom height of the lowermost layer of workpieces 100 on the tooling 101 is slightly higher than the top height of the feeding line. The main support plate 41 is driven by the lifting cylinder 4 to press down, so that the bottom of the sliding table 42 fits with the top of the uppermost layer of workpieces 100 stacked on the tooling 101. The U-shaped frame 5 and the palletizing arm follow the sliding table 42 to descend, and fall above the front lifting and feeding table and are close to the top of the lifted tooling 101. At this time, the workpiece 100 is surrounded by the U-shaped frame 5 and the one-way rotating plate 52.

[0038] To ensure that when the palletizing arm is reset along the pushing route after pushing out the workpiece 100, a section of moving gap is reserved. A layered chain plate that runs synchronously with the palletizing arm is also provided. The layered chain plate moves synchronously with the palletizing arm. When pushing out the bottom layer of workpieces 100, it effectively blocks the upper layer of workpieces 100 from moving down. Through the cooperation of the U-shaped frame 5 and the sliding table 42, the workpieces 100 are disassembled layer by layer, and the stacked structure is prevented from collapsing;

[0039] Such as Figure 2 、 Figure 4 and Figure 6As shown in the figure, the palletizing arm includes: two guiding seats mounted on the linear sliders of two linear guide pairs. The guiding seat 44 of the palletizing arm is rigidly connected to the driving rod of the driving cylinder 43 through the slider of the linear guide pair. When the driving cylinder 43 expands and contracts, it drives the guiding seat 44 to move horizontally along the guide rail, controlling the lateral stroke of the palletizing push plate 47. The smooth rod 45 is nested in the guiding seat 44 and is in sliding fit through a copper sleeve. The smooth rod 45 is nested in the guiding seat 44 and is in sliding fit through a copper sleeve. The movable push blocks 46 thread-fastened at the lower end of the smooth rod 45 respectively extend to the front and rear sides of the C-shaped frame 5, forming a stable cantilever support structure. A palletizing push plate 47 is arranged between the movable push blocks 46. When the palletizing push plate 47 moves horizontally, it remains parallel to the bottom of the C-shaped frame 5. A first spring 451 is wound around the smooth rod 45 on the front side. The first spring 451 is arranged between the guiding seat 44 and the movable push block 46, and is used to maintain the relative position between the palletizing push plate 47 and the C-shaped frame 5.

[0040] Among them, in order to realize the dynamic adjustment of the stacking height of the workpiece 100 on the tooling 101 by the C-shaped frame 5 and the palletizing arm, a limiting connecting rod 51 is also provided. The limiting connecting rod 51 is arranged between the sliding table 42 and the C-shaped frame 5. One end of it is hinged to the C-shaped frame 5, and the other end is hinged to the bottom of the sliding table 42. In addition, sliding grooves 501 are horizontally opened on the front and rear sides of the C-shaped frame 5. Pulley 55 is symmetrically installed on the inner side of the movable push block 46 in the front and rear directions. The two pulleys 55 are respectively located in one sliding groove 501 and can move left and right in the sliding groove 501. The position relationship between the movable push block 46 and the C-shaped frame 5 is limited by the sliding groove 501 and the pulley 55 to ensure that the two always remain coordinated during the movement process.

[0041] The guiding plate 54 is horizontally installed on the inner front side of the equipment frame 1, and a guiding strip is provided thereon. The height of the guiding strip is the same as the height of the tooling 101 after lifting. A guiding wheel 53 is installed on the front movable push block 46. When the sliding table 42 descends, the guiding wheel 53 will first contact the guiding strip. During the downward movement of the sliding table 42, under the action of the first spring 451, it will push the C-shaped frame 5 to a position away from the sliding table 42. The limiting connecting rod 51 swings to an inclined state close to the vertical. The C-shaped frame 5 descends with the sliding table 42 and encloses the workpiece 100 inside. The sliding table 42 is pressed down by the lifting cylinder 4. The guiding strip contacts the guiding wheel 53. Under the action of the first spring 451, the guiding wheel 53 always maintains an extrusion contact state with the guiding strip. The guiding seat continues to slide downward on the smooth rod 45. Under the mechanical limiting action between the pulley 55 and the sliding groove 501, the position of the C-shaped frame 5 remains unchanged and is always in a position close to the tooling 101, and there will be a gap for the palletizing push plate 47 to pass through between the tooling 101 and the C-shaped frame 5. And the limiting connecting rod 51 not only serves as a connecting component for height adjustment, but also can surround and block the workpiece 100 on the tooling 101 to prevent the workpiece 100 from shifting or collapsing during the palletizing process;

[0042] During the unstacking process, the unstacking push plate 47 slowly pushes the bottom layer of workpieces 100 on the tooling 101 towards the material transfer line. Under the action of the thrust force, the lowermost yoke is subjected to a squeezing force on the right side and comes into extrusion contact with the adjacent yoke workpiece 100, and is pushed concentratedly to the left. The lowermost yoke workpiece 100 is pushed to move to the left. At this time, since the upper layer of workpieces 100 is in close contact with the lower layer surface, it will slide along with the lower layer. During the movement, the upper layer of workpieces 100 is blocked by the guiding structures on both sides of the sliding table 42 and supported by the layered chain plates, maintaining a straight state and avoiding skewing. And during the movement, it is blocked by the one-way rotating plate 52. At the same time, the movement speed of the lower layer of workpieces 100 is gentle, and the weight of the upper layer is evenly dispersed, further avoiding the risk of sudden tilting or dropping. After the workpiece 100 is pushed out, a gap is formed between the lowermost layer of workpieces 100 and the tooling 101 under the lifting of the layered chain plates. Subsequently, the unstacking push plate 47 is controlled to reset. During the reset process, due to being blocked by the limit connecting rod 51 and the C-shaped frame 5 on the right side, the received workpiece 100 gradually comes into sliding contact with the layered chain plates and disengages from the chain plates, and falls back onto the tooling 101 again. A gap is formed between the uppermost layer of workpieces 100 and the bottom of the sliding table 42. The lifting cylinder 4 controls the sliding table 42 to press down. The position of the C-shaped frame 5 remains unchanged, and the limit connecting rod 51 rotates under force to maintain the blocking effect on the workpiece 100 until the sliding table 42 continues to contact the workpiece 100. Through the above steps repeated, all the workpieces 100 on the tooling 101 are disassembled layer by layer and all pushed out. Finally, the lifting cylinder 4 drives the main support plate 41 to rise and reset, the lifting material transfer table descends, so that the tooling 101 falls onto the conveying chain 31, and the tooling 101 is conveyed to the next process through the front conveying chain 31.

[0043] Among them, by adjusting the mechanism to limit the rotation angle of the one-way rotating plate 52, the height that the pushed material is allowed to pass through can be controlled, so that the one-way rotating plate 52 forms a limiting interface for the second layer of workpieces 100 at the bottom on the tooling 101, ensuring that when the lowermost layer of workpieces 100 surrounded by the C-shaped frame 5 is successively pushed to the material transfer line by the unstacking arm, the one-way rotating plate 52 will be pushed by the workpiece 100 pushed outwards and swing, and at the same time block the second layer of workpieces 100 at the lower part of the stack on the tooling 101, only allowing the current layer of workpieces 100 to pass through. In this way, all the workpieces 100 on one layer close to the top of the tooling 101 can be pushed out onto the material transfer line at one time.

[0044] Such as Figure 8 and Figure 9As shown in the figure, the layered chain plate includes: a chain plate box 7, fixedly installed on one side inside the equipment frame 1, whose internal structure is closely matched with the external frame, ensuring the stability of the entire layered chain plate system. A partition supporting chain 71 is arranged inside the chain plate box 7. The partition supporting chain 71 is composed of multiple high-strength and wear-resistant chain plates linked together, having good flexibility and supporting performance. One end of the partition supporting chain 71 is firmly connected to one side of the unstacking push plate 47 through a strong connecting piece. This connection method not only ensures the force transmission efficiency but also enables the partition supporting chain 71 to be smoothly withdrawn from the chain plate box 7 along with the movement of the unstacking push plate 47. The two ends of a single chain plate are respectively designed with an extending convex block 720 and a lapping slot 721. When the partition supporting chain 71 is flattened, the extending convex block 720 on the chain plate will accurately engage into the lapping slot 721 of its previous chain plate, thereby forming a continuous and stable planar structure. This not only ensures the integrity of the partition chain plate when it is unfolded laterally but also can effectively carry the workpiece 100, avoiding the occurrence of sagging due to gravity and maintaining its top plane always in a horizontal state, providing a reliable support for the workpiece 100.

[0045] In addition, in order to realize the automatic reset function of the layered chain plate, a second spring 73 is also arranged inside the chain plate box 7. The two ends of the second spring 73 are respectively and firmly connected to the end of the partition supporting chain 71 and the chain plate box 7. The second spring 73 has sufficient elastic restoring force and can gradually draw the partition supporting chain 71 into the chain plate box 7 through the pulling force during the reset process of the unstacking push plate 47.

[0046] Among them: As Figure 2 、 Figure 10 and Figure 11 shown in the figure, the material conveying line includes: a material conveying frame 8. The feeding end of the material conveying frame 8 is arranged inside the equipment frame 1, while its discharging end extends backward to the outside of the equipment frame 1, and only allows one workpiece 100 to be conveyed through the discharging end. Through the bending design in the middle section of the material conveying line, the feeding end and the discharging end are in a parallel state, thereby optimizing the space utilization rate with this layout.

[0047] A conveyor frame 8 is provided with a first conveyor belt 81 which is precisely laid along the conveying path and is used to steadily convey the workpieces 100 outwards. In addition, second conveyor belts 82 are symmetrically installed at the front and rear on one side of the feeding end of the conveyor frame 8. The two second conveyor belts 82 are respectively located on the front and rear sides of the first conveyor belt 81, and the conveying direction of the second conveyor belts 82 is the same as that of the first conveyor belt 81. Such a layout forms a relatively wide plane at the feeding end of the conveying line and can temporarily store multiple materials pushed out in layers. When the workpiece 100 is unloaded from the tooling 101 in the equipment frame 1, it is first received by the first conveyor belt 81 and the second conveyor belts 82, and the wide temporary storage area is used to simultaneously carry multiple workpieces 100. Subsequently, through the tapered section provided in the middle of the conveyor frame 8, through guiding and spatial constraints, the workpieces 100 are gradually arranged individually, and finally enter the first conveyor belt 81 in an orderly manner and are steadily conveyed out of the feeding end.

[0048] Finally, on the basis of the above structure, the adjusting mechanism includes: a fixed seat 6, whose installation position is on one side of the U-shaped frame 5 close to the one-way rotating plate 52. A sliding block is installed in the fixed seat 6 in a left-right sliding manner. This sliding connection method enables the sliding block to adjust its position within the fixed seat 6. At the same time, a limiting block 62 is connected to the sliding block within the fixed seat 6, and its position is exactly on the rotation path of the one-way rotating plate 52. This layout ensures that the limiting block 62 can effectively limit and adjust the rotation range of the one-way rotating plate 52. In addition, an adjusting rod 61 is inserted through the fixed seat 6, and its outer part is provided with threads. One end of it passes through the inner side of the sliding block and is rotatably connected to the U-shaped frame 5, while the sliding block is connected to the adjusting rod 61 in a screwed connection manner. When the adjusting rod 61 rotates, due to the effect of the threads, the sliding block will adjust its position in the left-right direction within the fixed seat 6, thereby driving the limiting block 62 to move synchronously. In this way, the distance between the limiting block 62 and the one-way rotating plate 52 can be accurately adjusted, and thus the precise control of the rotation range of the one-way rotating plate 52 can be achieved. This design not only improves the flexibility and adaptability of the equipment but also provides convenient conditions for operations under different working conditions.

[0049] When the height or size of the workpiece 100 changes, the rotation range of the one-way rotating plate 52 needs to be adjusted accordingly to ensure that the workpiece 100 can pass through smoothly and maintain a stable state. At this time, the operator can achieve this purpose by rotating the adjusting rod 61. Specifically, since the adjusting rod 61 is connected to the sliding block in a screwed connection manner and the adjusting rod 61 is provided with threads, when the adjusting rod 61 is rotated, the sliding block will make precise position adjustment in the left-right direction within the fixed seat 6. This adjustment will directly drive the limit block 62 connected to the sliding block to move synchronously, thereby changing the spacing distance between the limit block 62 and the one-way rotating plate 52. For example, when the height of the workpiece 100 decreases, the spacing between the limit block 62 and the one-way rotating plate 52 can be appropriately reduced to limit the rotation amplitude of the one-way rotating plate 52 and prevent the workpiece 100 from tipping over or getting stuck due to excessive rotation of the rotating plate; conversely, when the height of the workpiece 100 increases, this spacing can be increased to give the one-way rotating plate 52 a larger rotation range to ensure that the workpiece can pass through smoothly. The device can flexibly adjust the rotation range of the one-way rotating plate 52 according to workpieces 100 of different sizes and heights, so as to adapt to diverse production requirements.

[0050] Compared with the prior art, the present invention can be flexibly adapted to yoke workpieces of different sizes and models; the unstacking arm directly acts on the bottom layer of the workpiece 100, and realizes continuous feeding without pre-stratification through interlayer sliding peeling. The traditional feeding method often cannot push out multiple stacked workpieces 100 at one time or can only disassemble them one by one. This limitation is mainly reflected in the following aspects: First, traditional equipment usually lacks an effective stratification mechanism or can only realize the disassembly of a single stack of materials one by one; second, the existing feeding method may require manual or sorting equipment to pick up and feed one by one, with low efficiency and easy to make mistakes; third, some automated equipment uses multi-gripper manipulators. Although they can realize the layer-by-layer decomposition of the workpiece 100, this multi-gripper manipulator has obvious defects. Its gripper positions are fixed, and the number of stacked workpieces 100 and their positions need to correspond to the number of grippers. The structure is complex and it needs to be used in conjunction with specific equipment, with extremely low flexibility. Once the production requirements change, such as the size and shape of the workpiece 100 change, the entire equipment may need to be adjusted and modified on a large scale, increasing the production cost and maintenance difficulty.

[0051] Embodiment 2

[0052] On the basis of Embodiment 1, as Figure 6As shown in the figure, it further includes a force - applying pressure plate 421 elastically mounted at the bottom of the sliding table 42 through an elastic member 422. The force - applying pressure plate 421 can lift and lower synchronously with the sliding table 42. During the descent of the sliding table 42, the force - applying pressure plate 421 will come into contact with the workpiece first. Due to the existence of the elastic member 422, the force - applying pressure plate 421 can dynamically compensate according to the actual stacking height of the workpiece 100, thereby maintaining the stability of the stacking state of the workpiece 100 and avoiding deformation or damage of the workpiece 100 caused by direct pressure from the sliding table 42. At the same time, this design effectively avoids rigid impacts and reduces the risk of damage to the equipment and materials.

[0053] As Figure 10 shown in the figure, it further includes: a rotating bracket 9, which is stagger - installed on the front and back sides of the feeding end of the material - conveying frame 8. Its layout is designed with front - and - back dislocation to avoid action conflicts between adjacent brackets and form multiple - level guiding areas at the same time. The mounting shaft of the rotating bracket 9 allows it to rotate freely and can adjust the angle along with the transmission path of the workpiece 100; a sliding rod 91 is horizontally slidably arranged on the rotating bracket 9 through a slide - rail structure to realize the lateral position adjustment of the baffle 92. The baffle 92 is fixed inside the sliding rod 91 and extends into the upper part of the material - conveying frame 8. During the lateral transmission process of the conveyor belt 1 81 and the conveyor belt 2 82, the longitudinal offset of the workpiece 100 is restricted by physical blocking. The angle of the baffle 92 is adjusted through a hinge structure. Loosen the locking device and the tilt angle can be manually adjusted and then fixed to maintain the set posture; when the workpiece 100 enters the material - conveying frame 8, the conveying line conveys the material, and the inclined baffle 92 guides the workpiece 100 through the decomposition of the contact force: after the workpiece 100 contacts the baffle 92, the moving direction is decomposed into the sliding direction along the surface of the baffle 92 and the direction perpendicular to the baffle 92, so as to gradually correct the disordered workpiece 100 into a linear arrangement.

[0054] As Figure 11 shown in the figure, it further includes: a flat workbench 10 arranged on the upper side of the rear part of the equipment frame 1, with a notch opened on it to allow the material at the discharging end of the material - conveying frame 8 to pass through, allowing the discharging end of the material - conveying frame 8 to pass through directly. The conveying line extends backward from this point, horizontally exits to the right from the rear part of the equipment frame 1, and the end is parallel to the ground, making the conveying path and the processing area overlap in the vertical direction, avoiding the lateral expansion of the equipment footprint. In addition, an installation seat 11 is provided on one side of the discharging end of the material - conveying frame for installing the processing equipment of the workpiece 100, which can enter the processing area without secondary transfer, eliminating the robotic arm or conveyor belt required for material transfer in the traditional production line, reducing the equipment complexity and energy consumption; shortening the production cycle time, the processing components and the discharging action of the material - conveying frame 8 are synchronized in real - time: when the workpiece 100 is conveyed to the workbench 10 through the notch, the processing components on the installation seat 11 can immediately respond, realizing seamless connection of the "conveying - processing" actions and reducing the idle waiting time.

[0055] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and all technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
