Description

Technical Field

[0001] This invention relates to the field of machine tool loading equipment technology, specifically to an automated machine tool loading device. Background Technology

[0002] The loading device of automated machining tools is a key supporting equipment in the field of mechanical processing, connecting workpiece storage and machine tool processing. Its core function is to accurately and stably transport the workpieces to be processed to the machine tool's picking station according to a preset rhythm and posture, providing a continuous supply of workpieces for the robotic arm or the machine tool's built-in picking mechanism. As an important component of automated production lines, this device directly affects the machine tool's processing efficiency, workpiece processing accuracy, and the degree of automation in the production process. It is applied to various batch processing scenarios such as hardware processing, automotive parts manufacturing, and electronic component production, and is one of the core supports for achieving unmanned and efficient operation of the processing process.

[0003] Early machine tool loading devices mostly consisted of simple conveyor belts and manually assisted pushing mechanisms. Their operation relied on manual intervention to complete operations such as workpiece placement and position calibration. This not only resulted in high labor intensity and labor costs, but also caused inaccurate workpiece positioning due to human error, thus affecting processing accuracy. At the same time, the pace of manual loading was difficult to match precisely with the machine tool's processing speed, often resulting in machine stoppages due to waiting for materials or workpiece accumulation, which seriously restricted production efficiency. To solve these problems, existing technologies have gradually developed automated loading devices that integrate conveying components, positioning mechanisms, and adjustment structures. These devices use motor-driven transmission components to transport workpieces and utilize cylinders, sensors, etc., to achieve positioning and attitude adjustment, effectively reducing reliance on manual labor and improving the level of automation in loading.

[0004] However, existing devices still have significant shortcomings: the feeding process of existing devices often requires lifting the feeding tray to the top of the equipment or a high place for replenishment, which is not only inconvenient to operate, but also causes workpieces to bump and fall due to the high placement of materials; although some devices reduce the feeding height through a simple lifting structure, their lowering feeding mechanism uses a single locking transmission method. During the separation and resetting process of the moving plate and the transmission components, there is a lack of a stable positioning and limiting structure, which can lead to problems such as moving plate offset and inaccurate locking, thus affecting the subsequent feeding rhythm. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a feeding device for automated machine tools, which solves the problem that the lowering feeding mechanism, due to its single transmission method and lack of a stable positioning and limiting structure, will experience issues such as moving plate misalignment and inaccurate engagement, thus affecting the feeding rhythm.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a feeding device for an automated processing machine tool, comprising a machine table and multiple movable plates, wherein the multiple movable plates are disposed on the top of the machine table, a feeding tray is disposed above the movable plates, and a lowering feeding mechanism and a transmission assembly are disposed on the inner side of the machine table;

When the hydraulic lifting rod drives the lifting plate to move down, causing the T-shaped clamping plate to disengage from the grooved clamping plate, the clamping cylinder drives the rack to move relative to each other, so as to clamp the lowering feeding tray through the locking post.

[0009] Preferably, the top of the equipment platform is fixedly connected to a plurality of sliding wheels, and the movable plate is slidably disposed above the plurality of sliding wheels;

[0010] The top of the movable plate is rotatably connected to multiple L-shaped limiting rods, the feeding tray is located on the outside of the L-shaped limiting rods, and auxiliary pulleys are fixedly connected to both sides of the top of the lifting plate.

[0011] The inner side of the equipment platform is also provided with a material guiding adjustment mechanism and a single-sided support mechanism. The material guiding adjustment mechanism is located outside the lowering feeding mechanism to guide the workpiece to be processed into the feeding tray. The single-sided support mechanism is used to assist the robotic arm in picking up the material.

[0012] Preferably, the single-sided support mechanism includes a linear slide assembly, which is fixedly connected to the inner side of the equipment platform. A sliding plate is fixedly connected to the moving end of the linear slide assembly. A rotating rod is rotatably connected to the top of the sliding plate. A limiting sleeve is slidably connected to the outer side of the rotating rod. A hollow strip is fixedly connected to the outer wall of the limiting sleeve. A limiting slide is provided on the inner side of the hollow strip. An adjusting cylinder is fixedly connected to the inner side of the equipment platform. The telescopic end of the adjusting cylinder is fixedly connected to the outer side of the limiting slide. A T-shaped plate is fixedly connected to the top of the rotating rod. A locking hole is provided on the outer side of the feeding tray, and the locking hole is inserted into the T-shaped plate.

[0013] Preferably, the transmission assembly includes a drive motor, which is fixedly connected to the inner side of the equipment platform. Multiple sprockets are rotatably connected to the top of the equipment platform, and the multiple sprockets are connected to each other by a chain. Multiple grooved plates are fixedly connected to the outer side of the chain.

[0014] Preferably, a locking cylinder is fixedly connected to the top of the equipment platform, and a conical block is fixedly connected to the telescopic end of the locking cylinder. The conical block is inserted into the movable plate. A support column is fixedly connected to the top of the equipment platform, and an infrared sensor is fixedly connected to the outside of the support column.

[0015] Preferably, a buffer pad is provided on the top of the electromagnetic suction block, and the buffer pad is adapted to contact the bottom of the moving plate.

[0016] Preferably, the top of the L-shaped guide plate is provided with an inclined material guiding surface, and the plurality of engaging grooves are arranged at intervals along the length direction of the L-shaped guide plate.

[0017] Preferably, a wear-resistant bushing is provided between the rotating rod and the limiting sleeve, and the limiting slide bar is slidably connected to the inner side of the hollow bar.

[0018] Preferably, a cover plate is installed on the top of the equipment platform, and the cover plate is disposed on the top of the transmission assembly.

[0019] This invention provides a feeding device for an automated machine tool. It has the following advantages:

[0020] 1. This invention places the movable plate above the sliding wheels of the equipment table, starts the drive motor to drive the sprocket and chain to rotate, and moves the movable plate by engaging the grooved clamping plate and the T-shaped clamping plate. When the movable plate moves above the lifting plate, the electromagnetic suction block slides up along the limiting column to attract the lifting plate and limit the position of the movable plate. Then, the hydraulic lifting rod is started to move the lifting plate down, so that the grooved clamping plate and the T-shaped clamping plate are disengaged. When the feeding tray moves down to the inside of the equipment table, the clamping cylinder pushes the rack, and the two racks move relative to each other through gear transmission. The feeding tray is clamped by the clamping column. Finally, the hydraulic lifting rod moves the lifting plate down to the bottom to complete the feeding preparation. Therefore, it is not necessary to put the workpiece from a high place, which reduces the difficulty of manual feeding operation and improves the safety and convenience of feeding.

[0021] 2. In this invention, the J-shaped support plate moves down synchronously with the lifting plate. According to the workpiece specifications, the knob block is rotated to rotate the lead screw, which pushes the trapezoidal support platform to slide along the slide rail to adjust the spacing. The L-shaped guide plate moves with the trapezoidal support platform, and the cross bracket rotates and unfolds to support. The L-shaped locking plate is fixed with bolts to the corresponding locking groove to fix the position of the L-shaped guide plate. The external feeding mechanism sends the workpiece above the two L-shaped guide plates, and it falls into the feeding tray after being blocked by the limiting baffle. The hydraulic lifting rod rises synchronously with the workpiece until the guiding adjustment mechanism is in contact with the feeding tray. The clamping cylinder retracts to release the clamp, thereby adapting to workpieces of different sizes. The cooperation between the guide plate and the baffle prevents the workpiece from falling off-center, and the cross bracket support improves the stability of the guiding structure.

[0022] 3. In this invention, the feeding tray is moved to the material picking position of the robotic arm. The locking cylinder pushes the conical locking block to engage and lock the moving plate. The linear slide group is activated, which drives the sliding plate to move upward, so that the T-shaped plate is higher than the moving plate. The adjusting cylinder pushes the limiting slide bar to slide, which drives the limiting sleeve and the rotating rod to rotate, so that the T-shaped plate is between the feeding tray and the moving plate. The linear slide group continues to move upward, so that the T-shaped plate is locked into the locking hole. The infrared sensor scans and monitors. After the robotic arm picks up the top workpiece, the linear slide group pushes the feeding tray to move upward. After the workpiece is picked up, the linear slide group moves downward, and all components are reset in reverse. The locking cylinder retracts to release the locking, thereby realizing automatic lifting and filling of the workpiece, ensuring that the robotic arm picks up the material in a consistent position, and the locking structure prevents the moving plate from shifting during material picking.

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see the appendix Figure 1 Appendix Figure 4 Appendix Figure 5 Appendix Figure 6 and attached Figure 9 This invention provides a feeding device for an automated processing machine tool, including a machine platform 1 and multiple movable plates 6. The multiple movable plates 6 are arranged on the top of the machine platform 1, and a feeding tray 7 is arranged above the movable plates 6. A lowering feeding mechanism 2 and a transmission assembly 5 are arranged on the inner side of the machine platform 1.

[0036] The transmission assembly 5 is provided with a grooved plate 26 on the outside, and the movable plate 6 is fixed with a T-shaped plate 25 that engages with the grooved plate 26 on the outside.

[0037] The lowering feeding mechanism 2 includes a hydraulic lifting rod 21 and a lifting plate 22 driven by it. A limiting column 23 is fixed to the top of the lifting plate 22. An electromagnetic suction block 24 for adsorbing upward and limiting the movement of the plate 6 is slidably connected to the limiting column 23. A clamping cylinder 28 is also fixed inside the equipment platform 1 and is rotatably connected to a gear 29. A rack 210 is meshed on both sides of the gear 29. A locking column 211 is fixed on the rack 210. When the hydraulic lifting rod 21 drives the lifting plate 22 to move downward, so that the T-shaped clamping plate 25 is disengaged from the grooved clamping plate 26, the clamping cylinder 28 drives the rack 210 to move relative to each other, so as to clamp the lowering discharge tray 7 through the locking column 211.

[0038] Multiple sliding wheels 8 are fixedly connected to the top of the equipment platform 1, and the movable plate 6 is slidably disposed above the multiple sliding wheels 8;

[0039] Multiple L-shaped limiting rods 13 are rotatably connected to the top of the movable plate 6, the feeding tray 7 is set on the outside of the L-shaped limiting rods 13, and auxiliary pulleys 27 are fixedly connected to both sides of the top of the lifting plate 22.

[0040] The inner side of the equipment platform 1 is also equipped with a material guiding adjustment mechanism 3 and a single-sided support mechanism 4. The material guiding adjustment mechanism 3 is located on the outside of the lowering feeding mechanism 2 to guide the workpiece to be processed into the feeding tray 7. The single-sided support mechanism 4 is used to assist the robotic arm in picking up materials.

[0041] The top of the electromagnetic suction block 24 is provided with a buffer pad, which is adapted to contact the bottom of the moving plate 6. The transmission component 5 includes a drive motor 51, which is fixedly connected to the inner side of the equipment platform 1. Multiple sprockets 52 are rotatably connected to the top of the equipment platform 1. The multiple sprockets 52 are connected to each other through a chain 53. Multiple grooved plates 26 are fixedly connected to the outer side of the chain 53.

[0042] Specifically, a movable plate 6 is horizontally placed above the sliding wheel 8 of the equipment platform 1. A T-shaped clamping plate 25 is located on the outer side of the movable plate 6. By starting the drive motor 51, the sprocket 52 rotates. The rotation of the sprocket 52 then rotates the outer chain 53. Simultaneously, due to the multiple grooved clamping plates 26 fixed to the outer side of the chain 53, the grooved clamping plates 26 move with the chain 53 and engage with the T-shaped clamping plates 25, causing the movable plate 6 to move above the sliding wheel 8. This allows the workpiece to move towards the robotic arm's pick-up point along with the feeding tray 7 above the movable plate 6. After a set of workpieces is processed, the movable plate 6 moves towards the lowering feeding mechanism 2 driven by the chain 53. When the movable plate 6 moves above the lifting plate 22 driven by the chain 53, the electromagnetic suction block 24 above the lifting plate 22 is activated. The electromagnetic suction block 24 slides upward on the limiting column 23 and is attracted to the lifting plate 22. Since the electromagnetic suction block 24 only slides slightly on the limiting column 23 and is limited by the limiting column 23, the moving plate 6 is restricted above the lifting plate 22. Then, the hydraulic lifting rod 21 is activated to drive the lifting plate 22 to move downward. During the downward movement, the grooved clamping plate 26 and the T-shaped clamping plate 25 are disengaged. When the feeding tray 7 moves to the inside of the equipment table 1, the clamping cylinder 28 is activated to push the rack 210 on the front side to move. Under the action of the gear 29, the rack 210 on the other side moves relative to it, so that the clamping column 211 above the rack 210 clamps the feeding tray 7, so that the feeding tray 7 will not continue to move downward until the hydraulic lifting rod 21 drives the lifting plate 22 to move to the bottom, so that the workpiece to be processed can be added without placing the workpiece from a high place.

[0043] See appendix Figure 2 Appendix Figure 5 and attached Figure 8 The material guiding adjustment mechanism 3 includes a J-shaped support plate 31, which is fixedly connected to the outside of the hydraulic lifting rod 21. A pad 32 is fixedly connected to the top of the J-shaped support plate 31, and a slide rail 33 is fixedly connected to the top of the pad 32. Two trapezoidal support platforms 34 are slidably connected to the outside of the slide rail 33. A screw 35 is provided between the two trapezoidal support platforms 34. One end of the screw 35 is rotatably connected to one of the trapezoidal support platforms 34, and a knob block 39 is fixedly connected to the other end of the screw 35. The outside of the screw 35 is threadedly connected to the inside of the other trapezoidal support platform 34. An L-shaped guide plate 36 is slidably connected to the top of the trapezoidal support platform 34. A cross bracket 37 is slidably connected to the bottom of the two L-shaped guide plates 36. A limiting baffle 38 is slidably connected to the left side of the two L-shaped guide plates 36. An L-shaped locking plate 310 is slidably connected to the outer wall of the right trapezoidal support platform 34. A locking groove 311 is opened on the outside of the right L-shaped guide plate 36.

[0044] The top of the L-shaped guide plate 36 is provided with an inclined material guiding surface, and multiple engaging grooves 311 are arranged at intervals along the length of the L-shaped guide plate 36.

[0045] Specifically, during the downward movement of the lowering feeding mechanism 2, the J-shaped support plate 31 moves along with the lowering plate 22. At this time, the pad 32 above the J-shaped support plate 31 and the structure above it move together. According to the required workpiece size, rotating the knob block 39 causes the lead screw 35 to rotate, thereby pushing the trapezoidal support platform 34 to slide above the slide rail 33, adjusting the distance between the two trapezoidal support platforms 34. Simultaneously, the L-shaped guide plate 36 moves along with the trapezoidal support platform 34, and the cross bracket 37 sliding under the two L-shaped guide plates 36 rotates and unfolds to provide support for the L-shaped guide plate 36. Meanwhile, the limiting baffle 38 blocks the workpiece, preventing it from falling off-center. At the same time, the L-shaped locking plate 310 engages with the engaging groove 311 above the L-shaped guide plate 36 and is fixed with bolts, thus restricting the L-shaped guide plate 36 above the trapezoidal support platform 34. When the position needs to be adjusted, the bolts can be rotated to release the fixation. After adjusting the L-shaped guide plate 36 to the required position, the bolts are rotated again to fix it. Then, the workpieces are sequentially fed by the external feeding mechanism to the two L-shaped guide plates 36 and fall into the lower feeding tray 7 under the obstruction of the limiting baffle 38. At the same time, the hydraulic lifting rod 21 starts to rise. Each time a workpiece falls, the hydraulic lifting rod 21 will drive the structure above the lifting plate 22 to rise to a certain height, and the guide adjustment mechanism 3 will also rise until it is in contact with the clamped feeding tray 7. At this time, the clamping cylinder 28 retracts, releasing the clamping column 211 from the feeding tray 7. Then, the hydraulic lifting rod 21 pushes the lifting plate 22 to the highest point. At this time, the groove clamping plate 26 and the T-shaped clamping plate 25 re-clamp, the electromagnetic suction block 24 is released from magnetic attraction, and falls under its own gravity. Then, it moves under the drive of the chain 53 to allow the next group to repeat the feeding.

[0046] See appendix Figure 1 Appendix Figure 3 and attached Figure 10 The single-sided support mechanism 4 includes a linear slide assembly 41, which is fixedly connected to the inner side of the equipment platform 1. The moving end of the linear slide assembly 41 is fixedly connected to a slide plate 42. The top of the slide plate 42 is rotatably connected to a rotating rod 43. The outer side of the rotating rod 43 is slidably connected to a limiting sleeve 44. The outer wall of the limiting sleeve 44 is fixedly connected to a hollow strip 47. The inner side of the hollow strip 47 is provided with a limiting slide 46. The inner side of the equipment platform 1 is fixedly connected to an adjusting cylinder 45. The telescopic end of the adjusting cylinder 45 is fixedly connected to the outer side of the limiting slide 46. The top of the rotating rod 43 is fixedly connected to a T-shaped plate 48. The outer side of the feeding tray 7 is provided with a locking hole 49, which is inserted into the T-shaped plate 48.

[0047] A wear-resistant bushing is provided between the rotating rod 43 and the limiting sleeve 44 of the single-sided support mechanism 4, and the limiting slide bar 46 is slidably connected to the inner side of the hollow bar 47.

[0048] Specifically, when the unloading tray 7, filled with workpieces, moves to the robotic arm's pick-up point, the locking cylinder 9 is activated, pushing the conical locking block 14 to engage and lock the moving plate 6. Then, the linear slide assembly 41 is activated, causing the slide plate 42 to move upwards, driving the rotating rod 43 and the upper T-shaped plate 48 to move together until the bottom of the T-shaped plate 48 is higher than the top of the moving plate 6. At this point, the adjusting cylinder 45 is activated, pushing the limiting slide bar 46 to move, causing the limiting slide bar 46 to slide inside the hollow strip 47. This causes the limiting sleeve 44 to rotate, driving the rotating rod 43 and the upper T-shaped plate 48 to rotate together, causing the T-shaped plate... 48 rotates between the feeding tray 7 and the moving plate 6. Then, the linear slide group 41 continues to run, pushing the rotating rod 43 upward, so that the T-shaped plate 48 engages in the locking hole 49. Under the scanning of the infrared sensor 12, after the robotic arm removes the workpiece at the top, the linear slide group 41 will be activated, pushing the feeding tray 7 upward, so that the next workpiece moves to the highest point. Until all the workpieces are removed, the linear slide group 41 will drive the slide plate 42 downward, reversing the previous steps, until the slide plate 42 moves to the lowest point. At this time, the locking cylinder 9 retracts, releasing the engagement, and the chain 53 drives the next set of feeding trays 7 to perform the feeding process.

[0049] See appendix Figure 1 Appendix Figure 2 and attached Figure 3 A locking cylinder 9 is fixedly connected to the top of the equipment platform 1. A conical block 14 is fixedly connected to the telescopic end of the locking cylinder 9. The conical block 14 is inserted into and cooperates with the moving plate 6. A support column 11 is fixedly connected to the top of the equipment platform 1. An infrared sensor 12 is fixedly connected to the outside of the support column 11. A cover plate 10 is installed on the top of the equipment platform 1. The cover plate 10 is set on the top of the transmission assembly 5.

[0050] Specifically, the telescopic end of the locking cylinder 9 is fixedly connected to the conical locking block 14. When the feeding tray 7 moves to the picking station, the conical locking block 14 can quickly engage with the slot of the moving plate 6 under the drive of the locking cylinder 9, locking the moving plate 6 to prevent deviation during picking and ensure picking accuracy. The infrared sensor 12 installed on the outside of the support column 11 can monitor the height and remaining quantity of the workpiece in the feeding tray 7 in real time and transmit signals to the control system in a timely manner, so that the single-sided support mechanism 4 can complete the lifting and filling, ensuring that the robotic arm can pick up the material in the same position every time. The cover plate 10, which is arranged corresponding to the transmission component 5, is hinged to the top of the equipment platform 1. It can block the dust and debris from the outside, prevent them from entering the transmission components of the sprocket 52 and chain 53 and causing wear, thus extending the service life of the equipment. It can also be easily opened and closed, which is convenient for subsequent inspection, maintenance and replacement of parts of the transmission component 5.

[0051] Working principle: First, the moving plate 6 is placed horizontally above the sliding wheel 8 on the top of the equipment platform 1, ensuring that the moving plate 6 can slide smoothly along the sliding wheel 8. The drive motor 51 in the transmission assembly 5 is started. The drive motor 51 outputs torque to drive the sprocket 52 to rotate. The sprocket 52 drives the outer chain 53 to perform cyclic motion through meshing transmission. Since multiple grooved plates 26 are fixedly connected to the outer side of the chain 53, and the grooved plates 26 and the T-shaped plates 25 on the outer side of the moving plate 6 are adapted to engage, the movement of the chain 53 is converted into the horizontal movement of the moving plate 6 along the sliding wheel 8 through the engaging action. This, in turn, drives the feeding tray 7 above the moving plate 6 to move towards the material pick-up point of the robotic arm. When all the workpieces in the feeding tray 7 have been processed, the chain 53 reverses and drives the moving plate 6 to reset to the lowering feeding mechanism 2. When the moving plate 6 moves precisely to the top of the lifting plate 22, the electromagnetic suction block 24 on the top limiting post 23 of the lifting plate 22 slides upward along the axis of the limiting post 23 and engages with the bottom of the moving plate 6. A magnetic attraction is formed, and the displacement of the moving plate 6 is restricted under the limiting action of the limiting column 23. Then, the hydraulic lifting rod 21 is activated, and its telescopic end drives the lifting plate 22 and the moving plate 6 above it to move down synchronously. During this process, the grooved clamping plate 26 and the T-shaped clamping plate 25 gradually disengage. When the feeding tray 7 moves down to the preset height inside the equipment platform 1, the clamping cylinder 28 is activated. The telescopic end of the clamping cylinder 28 pushes one side of the rack 210 to move linearly. The rack 210 drives the other side of the rack 210 to move linearly in the opposite direction through the meshing transmission with the gear 29. This causes the clamping column 211 fixed at the top of the two racks 210 to move closer together, forming a symmetrical clamping and fixing of the feeding tray 7. The hydraulic lifting rod 21 continues to drive the lifting plate 22 to move down to the lowest point of the stroke, completing the feeding preparation. Thus, it is not necessary to place the workpiece from a high place, which reduces the difficulty of manual feeding and avoids the problem of workpiece collision and falling when feeding from a high place, improving the safety and convenience of the feeding process.

[0052] Furthermore, through the material guiding adjustment mechanism 3, during the downward movement of the lifting plate 22 of the lowering feeding mechanism 2, the J-shaped support plate 31 fixedly connected to the outside of the lifting plate 22 moves synchronously with the lifting plate 22, thereby driving the pad 32 at the top of the J-shaped support plate 31 and the material guiding related structures mounted on the pad 32 to move synchronously downward. According to the specifications and dimensions of the workpiece to be replenished, the screw 35 is driven to rotate around its own axis by rotating the knob block 39. The screw 35, through the threaded transmission, pushes the trapezoidal support platform 34 sleeved on the screw 35 to slide horizontally along the slide rail 33 at the top of the pad 32, thereby adjusting the distance between the two trapezoidal support platforms 34. During the sliding of the trapezoidal support platform 34, the L-shaped guide plate 36 at its top moves synchronously with the trapezoidal support platform 34. The cross bracket 37 hinged at the bottom of the two L-shaped guide plates 36 rotates and unfolds accordingly, providing stable support for the L-shaped guide plates 36. The L-shaped locking plate 310 is bolted to the corresponding outer side of the L-shaped guide plate 36. The locking groove 311 of the position is fixedly connected to realize the position locking of the L-shaped guide plate 36 on the trapezoidal support platform 34. The external feeding mechanism conveys the workpieces to the area between the two L-shaped guide plates 36 in sequence. Under the blocking action of the limiting baffle 38 at one end of the L-shaped guide plate 36, the workpieces fall accurately along the guide surface of the L-shaped guide plate 36 into the lower feeding tray 7. Each time a workpiece falls into the feeding tray 7, the hydraulic lifting rod 21 synchronously drives the lifting plate 22 and the guiding adjustment mechanism 3 to move upward a certain distance until the top of the guiding adjustment mechanism 3 is in contact with the bottom of the clamped feeding tray 7. At this time, the telescopic end of the clamping cylinder 28 retracts, driving the two racks 210 to move in the opposite direction. The locking column 211 releases the clamp on the feeding tray 7. It can adapt to workpieces of different sizes. At the same time, the cooperation of the guide plate and the baffle prevents the workpiece from falling off-center. The support of the cross bracket 37 also improves the stability of the guiding structure and solves the problems of single size adaptation and workpiece falling position deviation.

[0053] Simultaneously, through the single-sided support mechanism 4, when the feeding tray 7 moves with the moving plate 6 to the preset position for the robotic arm to pick up the material, the locking cylinder 9 on the top of the equipment platform 1 is activated. Its telescopic end pushes the conical block 14 to move towards the moving plate 6 until the conical block 14 engages with the corresponding slot of the moving plate 6, thereby achieving the positioning and locking of the moving plate 6. The linear slide group 41 is then activated, and the moving end of the linear slide group 41 drives the slide plate 42 to move upward, thereby driving the rotating rod 43 on the slide plate 42 and the T-shaped plate 48 at the top to move upward synchronously until the T-shaped plate 48... The bottom end is higher than the top plane of the moving plate 6. Then, the adjusting cylinder 45 is activated. The telescopic end of the adjusting cylinder 45 pushes the limiting slide bar 46 to slide along the inner side of the hollow bar 47. Since the hollow bar 47 is fixedly connected to the outside of the limiting sleeve 44, the sliding of the limiting slide bar 46 is converted into the rotational motion of the hollow bar 47, which in turn drives the rotating rod 43 to rotate around the axis of the limiting sleeve 44, so that the T-shaped plate 48 rotates to the gap area between the feeding plate 7 and the moving plate 6. The linear slide group 41 continues to drive the slide plate 42 to move upward, causing the T-shaped plate 48 to engage. Infrared sensors 12 on the support column 11 of the equipment platform 1 scan and monitor the position of the workpiece on top of the feeding tray 7 in real time within the pre-set slots 49 on the outer side of the feeding tray 7. When the robotic arm removes a workpiece from the top, the infrared sensor 12 sends a signal back to the control system. The linear slide group 41 drives the slide plate 42 to move upward a certain distance, which in turn drives the feeding tray 7 to move upward synchronously through the T-shaped plate 48, raising the next workpiece to the preset height for the robotic arm to pick up. When all the workpieces above the feeding tray 7 have been removed, the linear slide group 41 drives the slide plate 42 to move downward. The adjusting cylinder 45 pushes the limiting slide bar 46 in the opposite direction, causing the rotating rod 43 and the T-shaped plate 48 to rotate in the opposite direction. The T-shaped plate 48 disengages from the locking hole 49 and rotates to the initial position. The linear slide group 41 continues to drive the slide plate 42 to move down to the lowest point of the stroke. The locking cylinder 9 retracts, and the conical locking block 14 releases the lock on the moving plate 6, realizing the automatic lifting and filling of the workpiece, ensuring the consistency of the robotic arm's material picking position. At the same time, the locking structure prevents the moving plate 6 from shifting during material picking, solving the problems of inaccurate material picking position and the moving plate 6 shaking affecting material picking efficiency.
