Description

Technical Field

[0001] This invention relates to the field of workpiece loading technology, and more specifically to a workpiece loading and conveying device with clamping components. Background Technology

[0002] Irregularly shaped workpieces are a general term in the industrial manufacturing field for workpieces with non-standard geometric shapes. They usually refer to parts that cannot be defined by a simple combination of conventional geometric shapes such as cuboids, cylinders, and spheres, and have unique or complex structures, dimensions, and shapes. In the field of automated production, irregularly shaped workpiece loading and conveying devices are automated material handling and conveying systems specifically designed for non-standard geometrically shaped workpieces. The core objective is to solve the pain points of irregularly shaped workpieces, such as easy jamming, difficult positioning, and difficulty in unifying posture, and to achieve precise and efficient transfer from material storage to processing and assembly stations.

[0003] Because the surface structure of irregular workpieces is relatively complex, when using common clamping tools to clamp them, only part of the workpiece is in contact with the clamping tool, and these contact points cannot be determined in advance. If most of the contact points are concentrated on one side of the workpiece, the workpiece will lose its balance and will easily fall off the clamp during movement, which will lead to damage to the workpiece.

[0004] Furthermore, for faster and more convenient transfer of irregularly shaped workpieces, they are usually arranged on a tray and then transported by a transfer vehicle. However, during the loading process, workers need to place the workpieces on the tray one by one onto the conveyor equipment, which then loads the workpieces. Finally, a robotic arm places the workpieces one by one onto the processing equipment. The whole process is quite complex and tedious, and manual loading is prone to errors. For example, the workpieces may collide with the conveyor equipment during loading, which not only poses a safety hazard to workers but also damages the workpieces. At the same time, the weight of the tray itself makes it easy to lose force when manually changing the tray, which not only poses a significant safety hazard but also reduces work efficiency, thus affecting the loading efficiency of the workpieces. Summary of the Invention

[0005] Technical problems to be solved

[0006] The purpose of this invention is to overcome the shortcomings of the prior art, adapt to practical needs, and provide a feeding and conveying device for irregularly shaped workpieces with clamping components to solve the above-mentioned technical problems.

[0008] To achieve the objectives of this invention, the technical solution adopted is as follows:

[0009] A non-circular workpiece feeding and conveying device with clamping components includes a workpiece processing equipment, a workpiece conveyor on the side of the workpiece processing equipment, and a feeding mechanism between the workpiece processing equipment and the workpiece conveyor.

[0010] The feeding mechanism includes a mounting bracket fixedly connected to the end of the workpiece conveyor. The mounting bracket has a C-shaped top seat located above. Support columns are fixedly connected to both ends of the bottom of the C-shaped top seat, and a pallet support plate is fixedly connected to the other end of the support column.

[0011] Both ends of the C-shaped top seat are fixedly connected to limit columns, and a transverse sliding frame is movably connected through the limit columns.

[0012] As a further technical solution of the present invention, the transverse sliding frame includes a U-shaped sliding frame placed on the top of the C-shaped top seat. Both ends of the U-shaped sliding frame are provided with limiting grooves corresponding to the limiting columns, and the limiting columns slide in cooperation with the inner side of the limiting grooves. The two ends of the U-shaped sliding frame are respectively provided with intersecting positive triangular top plates and reverse triangular top plates.

[0013] As a further technical solution of the present invention, the bottom of the C-shaped top seat is fixedly connected to an extension mounting bracket in a rectangular array, and the other end of the extension mounting bracket is fixedly connected to a linear module, and the linear module is located inside the support column, and a transverse sliding bracket is movably connected to the side of the linear module away from the support column.

[0014] As a further technical solution of the present invention, a movable top rod is fixedly connected above the transverse sliding frame and is arranged parallel to the U-shaped sliding frame. The movable top rod is located between the positive triangular top plate and the reverse triangular top plate, and both ends of the movable top rod are movably connected to contact rollers.

[0015] As a further technical solution of the present invention, the end of the U-shaped sliding frame away from the workpiece processing equipment is also fixedly connected to a feed extension frame. The feed extension frame has an L-shaped connecting frame, and one end of the L-shaped connecting frame is bolted to the U-shaped sliding frame, while the other end is provided with a through slot. Moreover, one end of the through slot is also provided with a spring receiving slot.

[0016] As a further technical solution of the present invention, a locking rod is slidably fitted on the inner side of the through slot, a compression spring is sleeved on the outer side of the locking rod, and one end of the compression spring is inserted into the inner side of the spring receiving slot.

[0017] One end of the locking rod extends through the through slot to the side of the L-shaped connecting frame, and the end of the locking rod extending to the side of the L-shaped connecting frame is fixedly connected to a shaft end baffle, while the end of the locking rod away from the shaft end baffle is provided with an inclined surface.

[0018] As a further technical solution of the present invention, the pallet support plate is provided with a workpiece tray, the workpiece tray has a workpiece placement bracket placed on the pallet support plate, the bottom of the workpiece placement bracket is symmetrically provided with a through groove, and the pallet support plate is integrally provided with a limiting protrusion corresponding to the through groove, and the workpiece placement bracket is movably connected to the pallet support plate through the sliding cooperation between the through groove and the limiting protrusion.

[0019] As a further technical solution of the present invention, a side baffle located on the side of the workpiece placement bracket is fixedly connected above the pallet support plate, and rectangular locking blocks are fixedly connected in a rectangular array on the side of the workpiece placement bracket away from the pallet support plate.

[0020] As a further technical solution of the present invention, the end of the locking rod away from the shaft end baffle is inserted between two adjacent rectangular locking blocks, and the inclined surface of the locking rod is located on the side closer to the workpiece conveyor.

[0021] The workpiece placement bracket is further provided with rectangular array-shaped workpiece placement grooves above it for placing irregularly shaped workpieces.

[0022] (3) Beneficial effects:

[0023] A. In this invention, the linear module first drives the transverse sliding frame to move laterally, causing the gripping claws below the transverse sliding frame to move above the irregularly shaped workpiece. Then, the gripping claws below the transverse sliding frame clamp the workpiece. The linear module then drives the transverse sliding frame to move in the opposite direction, moving the irregularly shaped workpiece above the workpiece processing table in the workpiece processing equipment. The workpiece is then placed on the workpiece processing table. As the linear module reciprocates, the irregularly shaped workpieces are loaded one by one. After all the irregularly shaped workpieces arranged laterally on the workpiece tray have been picked up, and the transverse sliding frame continues to move closer to the workpiece after placing the workpiece, the linear module continues to move closer to the workpiece processing table. When the workpiece processing equipment moves a certain distance to one side, it will also move a certain distance away from the workpiece processing equipment during the no-load return trip. Then, it will clamp the workpiece on the workpiece tray. When the contact rollers at both ends of the moving push rod contact the forward or reverse triangular top plate, the inclined surfaces of the forward and reverse triangular top plates will cause the moving push rod to push the U-shaped sliding frame to move back and forth. Then, the workpiece tray will automatically move forward through the push of the feed extension frame, and the workpiece tray that is no longer in use will be pushed out, ensuring continuous feeding during continuous processing. It can also realize the automatic replacement of workpiece trays, thereby improving feeding efficiency.

[0024] B. In this invention, when the contact roller at one end of the moving push rod contacts the positive triangular top plate, since the contact position between the contact roller and the positive triangular top plate is an inclined surface, when the moving push rod moves closer to the positive triangular top plate, it will push the positive triangular top plate to move away from the side where the moving push rod is, thereby driving the U-shaped sliding frame to move as a whole. The limiting grooves opened at both ends of the U-shaped sliding frame slide in cooperation with the limiting column, thereby causing the U-shaped sliding frame to drive the L-shaped connecting frame to move on the side of the workpiece tray. By utilizing the unidirectional movement cooperation between the L-shaped connecting frame and the workpiece tray, the workpiece tray is moved forward a certain distance, thereby realizing the automatic replacement of the workpiece tray and improving the replacement efficiency of the workpiece tray.

[0025] C. In this invention, after all the irregularly shaped workpieces on the workpiece tray are loaded, the rollers on the workpiece conveyor will push the workpiece tray to move closer to the tray support plate, so that one end of the workpiece placement bracket contacts the upper part of the tray support plate. At this time, the side baffle on the tray support plate positions the side of the workpiece placement bracket, and the limiting protrusion engages with the through groove at the bottom of the workpiece placement bracket. Through the sliding engagement between the through groove and the limiting protrusion, the movement direction of the workpiece placement bracket is limited to prevent the workpiece placement bracket from shaking during movement, thereby ensuring the smooth movement of the workpiece placement bracket. At the same time, the workpiece placement bracket can also push out the workpiece placement bracket in front to realize the automatic replacement of the workpiece placement bracket.

[0026] D. In this invention, when the contact roller at the end of the moving push rod contacts the positive triangular top plate, it pushes the U-shaped sliding frame to move, causing the U-shaped sliding frame to move the L-shaped connecting frame closer to the workpiece conveyor. Simultaneously, the locking push rod at the end of the L-shaped connecting frame moves. At this time, the inclined surface at the end of the locking push rod contacts the rectangular locking block on the side of the workpiece placement bracket, causing the locking push rod to retract towards the inside of the spring receiving groove until it passes the rectangular locking block and enters the groove at the other end of the rectangular locking block. Then, the contact roller at the other end of the moving push rod contacts the reverse triangular top plate, pushing the U-shaped sliding frame to move. The U-shaped sliding frame drives the L-shaped connecting frame to move away from the workpiece conveyor. At this time, the plane on the other side of the locking rod contacts the side of the rectangular locking block, thereby pushing the workpiece placement tray to move one row. After all the irregular workpieces in any row on the workpiece placement tray are loaded, the workpieces in the next row of the workpiece placement tray are moved to the bottom of the transverse sliding frame through the cooperation of the L-shaped connecting frame and the rectangular locking block, realizing automatic feeding of the workpiece tray. During this process, no manual intervention is required, reducing the labor intensity of the workers. Compared with manual movement of the workpiece tray, the loading efficiency is improved.

[0027] E. In this invention, when the locking rod approaches the workpiece conveyor, the inclined surface on one side of the locking rod contacts the edge of the rectangular locking block on the side of the workpiece placement bracket. As the L-shaped connecting frame drives the locking rod to continue moving, the inclined surface of the locking rod will move towards the inside of the spring receiving groove and compress the compression spring, causing the compression spring to retract into the spring receiving groove. When the locking rod passes the rectangular locking block, the compression spring will push the locking rod to reset until the locking rod is inserted into the other side of the rectangular locking block, and the plane on the other side of the locking rod contacts the plane of the rectangular locking block, thereby allowing the rectangular locking block to move.

[0028] F. In this invention, the lifting assembly pushes the rotating terminal downwards, using the gripping claws at the bottom of the rotating terminal to clamp the workpiece. At this time, the swing clamping frame is arranged in a rectangular array on the outside of the irregularly shaped workpiece. Then, the external air pump and air pipe cooperate to collect the air inside the air duct and pneumatic cavity, creating a negative pressure. This causes the telescopic slide to move the clamping plate closer to the workpiece surface. The clamping plate also moves the swing clamping frame. The positioning rods at both ends of the swing clamping frame contact the workpiece surface one after another. Through the rotational engagement between the mounting shaft and the connecting bushing, it is ensured that the positioning rods at both ends are in contact with the workpiece surface. Multiple positioning rods are used to clamp the workpiece, and the three air ducts are interconnected, ensuring that the clamping assembly can automatically adjust the relative position between the movable slide and the connecting hanger according to the shape of the workpiece. Moreover, the use of compressed air for operation improves the response speed during clamping, thereby improving the clamping efficiency. Attached Figure Description

Detailed Implementation

[0050] Please see Figure 1-7 A workpiece feeding and conveying device with clamping components includes a workpiece processing equipment 1, a workpiece conveyor 2 on the side of the workpiece processing equipment 1, and a feeding mechanism between the workpiece processing equipment 1 and the workpiece conveyor 2. The feeding mechanism places the irregular workpieces on the workpiece conveyor 2 one by one onto the workpiece processing equipment 1 for processing, eliminating the need for manual feeding, improving safety and reducing labor intensity.

[0051] The feeding mechanism includes a mounting bracket 3 fixedly connected to the end of the workpiece conveyor 2. The mounting bracket 3 has a C-shaped top seat 32 located above. Both ends of the bottom of the C-shaped top seat 32 are fixedly connected to support columns 31, and the other end of the support column 31 is fixedly connected to a tray support plate 11.

[0052] Both ends of the C-shaped top seat 32 are fixedly connected to limiting columns 34, and a transverse sliding frame 8 is movably connected through the limiting columns 34. The limiting columns 34 limit the transverse sliding frame 8, so that the transverse sliding frame 8 can only slide back and forth, preventing the transverse sliding frame 8 from moving up and down at the same time, and improving the stability of the transverse sliding frame 8 when it moves.

[0053] In this embodiment, please refer to Figure 8-12The transverse sliding frame 8 includes a U-shaped sliding frame 81 placed on top of the C-shaped top seat 32. Both ends of the U-shaped sliding frame 81 are provided with limiting grooves 82 corresponding to the limiting posts 34. The limiting posts 34 slide in cooperation with the inner side of the limiting grooves 82, so that the U-shaped sliding frame 81 can slide above the C-shaped top seat 32. Both ends of the U-shaped sliding frame 81 are respectively provided with intersecting positive triangular top plates 83 and reverse triangular top plates 84. At the same time, when the U-shaped sliding frame 81 moves, it will drive the positive triangular top plates 83 and reverse triangular top plates 84 at both ends to slide inside the C-shaped top seat 32.

[0054] Furthermore, the end of the U-shaped sliding frame 81 away from the workpiece processing equipment 1 is also fixedly connected to a feed extension frame 9. The feed extension frame 9 has an L-shaped connecting frame 91, and one end of the L-shaped connecting frame 91 is bolted to the U-shaped sliding frame 81. When the U-shaped sliding frame 81 moves, it will drive the L-shaped connecting frame 91 to move synchronously. The other end is provided with a through slot 96, and one end of the through slot 96 is also provided with a spring receiving slot 95.

[0055] More specifically, a locking rod 92 is slidably fitted on the inner side of the through slot 96, and a compression spring 93 is sleeved on the outer side of the locking rod 92. The cross-section of the locking rod 92 is stepped, and the compression spring 93 is located on the outer side of the thinner section. The shoulder of the locking rod 92 limits one end of the compression spring 93, while the other end of the compression spring 93 is inserted into the inner side of the spring receiving groove 95. The compression spring 93 applies an outward pushing force to the locking rod 92.

[0056] One end of the locking rod 92 extends through the through slot 96 to the side of the L-shaped connecting frame 91, and the end of the locking rod 92 extending to the side of the L-shaped connecting frame 91 is fixedly connected to the shaft end baffle 94. The shaft end baffle 94 can limit the locking rod 92, and the end of the locking rod 92 away from the shaft end baffle 94 is provided with an inclined surface.

[0057] By adopting the above technical solution, when the U-shaped sliding frame 81 moves, it will drive the L-shaped connecting frame 91 to move closer to the workpiece conveyor 2. At the same time, the locking rod 92 at the end of the L-shaped connecting frame 91 moves synchronously. At this time, the inclined surface at the end of the locking rod 92 contacts the side of the workpiece tray 4, thereby causing the locking rod 92 to retract into the spring receiving groove 95 until the locking rod 92 passes the side of the workpiece tray 4. Then, the U-shaped sliding frame 81 moves in the opposite direction, driving the L-shaped connecting frame 91 to move away from the workpiece conveyor 2. During the movement, the plane on the other side of the locking rod 92 engages with the side of the workpiece tray 4, thereby pushing the workpiece tray 4 to move one row. After all the irregularly shaped workpieces in any row on the workpiece tray 4 are loaded, the workpieces in the next row of the workpiece tray 4 are moved to the bottom of the transverse sliding frame 6 through the cooperation of the L-shaped connecting frame 91 and the rectangular locking block 44, realizing automatic feeding of the workpiece tray 4. During this process, no manual intervention is required, reducing the labor intensity of the workers. Compared with manual movement of the workpiece tray 4, the loading efficiency is improved.

[0058] Furthermore, a workpiece tray 4 is provided on the tray support plate 11. The workpiece tray 4 has a workpiece placement bracket 41 placed on the tray support plate 11. The bottom of the workpiece placement bracket 41 is symmetrically provided with a through groove 43. The tray support plate 11 is integrally provided with a limiting protrusion 111 corresponding to the through groove 43. The limiting protrusion 111 is located inside the through groove 43, so that the workpiece placement bracket 41 can only move back and forth and cannot move left and right, thereby ensuring the direction of movement of the workpiece placement bracket 41. The workpiece placement bracket 41 is movably connected to the tray support plate 11 through the sliding cooperation between the through groove 43 and the limiting protrusion 111.

[0059] A side baffle 112 located on the side of the workpiece placement bracket 41 is fixedly connected above the pallet support plate 11. The side baffle 112 has an inverted L-shaped cross section. The top of the side baffle 112 limits the vertical movement of the workpiece placement bracket 41 to prevent it from jumping up and down when it moves. Rectangular locking blocks 44 are fixedly connected in a rectangular array on the side of the workpiece placement bracket 41 away from the pallet support plate 11.

[0060] By adopting the above technical solution, after all the irregular workpieces on the workpiece tray 4 are loaded, the rollers on the workpiece conveyor 2 will push the workpiece tray 4 to move closer to the tray support plate 11, so that one end of the workpiece placement bracket 41 contacts the top of the tray support plate 11. At this time, the side baffle 112 on the tray support plate 11 positions the side of the workpiece placement bracket 41, and the limiting protrusion 111 is engaged with the through groove 43 at the bottom of the workpiece placement bracket 41. Through the sliding engagement between the through groove 43 and the limiting protrusion 111, the movement direction of the workpiece placement bracket 41 is limited, preventing the workpiece placement bracket 41 from shaking during movement, thereby ensuring the smooth movement of the workpiece placement bracket 41. At the same time, the workpiece placement bracket 41 can also push out the workpiece placement bracket 41 in front, realizing the automatic replacement of the workpiece placement bracket 41.

[0061] Furthermore, the end of the locking rod 92 away from the shaft end baffle 94 is inserted between two adjacent rectangular locking blocks 44, and the inclined surface of the locking rod 92 is located on the side closer to the workpiece conveyor 2.

[0062] The workpiece placement bracket 41 is also provided with workpiece placement grooves 42 arranged in a rectangular array above it for placing irregularly shaped workpieces. Placing the produced irregularly shaped workpieces into the workpiece placement grooves 42 makes automatic feeding more convenient.

[0063] By adopting the above technical solution, when the locking rod 92 approaches the workpiece conveyor 2, the inclined surface of one side of the locking rod 92 contacts the edge of the rectangular locking block 44 on the side of the workpiece placement bracket 41. As the L-shaped connecting frame 91 drives the locking rod 92 to continue moving, the inclined surface of the locking rod 92 will move towards the inside of the spring receiving groove 95 and compress the compression spring 93, causing the compression spring 93 to retract into the spring receiving groove 95. When the locking rod 92 passes the rectangular locking block 44, the compression spring 93 will push the locking rod 92 to reset until the locking rod 92 is inserted into the other side of the rectangular locking block 44, and the plane of the other side of the locking rod 92 contacts the plane of the rectangular locking block 44, thereby allowing the rectangular locking block 44 to move.

[0064] More specifically, the bottom of the C-shaped top seat 32 is fixedly connected to an extension mounting bracket 33 in a rectangular array, and the other end of the extension mounting bracket 33 is fixedly connected to a linear module 5, thereby installing the linear module 5 below the U-shaped sliding bracket 81. The linear module 5 is located inside the support column 31, and the side of the linear module 5 away from the support column 31 is movably connected to a transverse sliding bracket 6.

[0065] Furthermore, a movable top rod 61 is fixedly connected above the transverse sliding frame 6 and is arranged parallel to the U-shaped sliding frame 81. The movable top rod 61 is located between the forward triangular top plate 83 and the reverse triangular top plate 84, ensuring that the movable top rod 61 can move between the forward triangular top plate 83 and the reverse triangular top plate 84. Moreover, both ends of the movable top rod 61 are movably connected to contact rollers 62. When the contact rollers 62 contact the inclined surface of the forward triangular top plate 83 or the reverse triangular top plate 84, the U-shaped sliding frame 81 can be moved back and forth by the forward triangular top plate 83 and the reverse triangular top plate 84.

[0066] By adopting the above technical solution, when the contact roller 62 at one end of the moving push rod 61 contacts the positive triangular top plate 83, since the contact position between the contact roller 62 and the positive triangular top plate 83 is an inclined surface, when the moving push rod 61 moves closer to the positive triangular top plate 83, it will push the positive triangular top plate 83 to move away from the moving push rod 61, thereby driving the U-shaped sliding frame 81 to move as a whole. The limiting grooves 82 opened at both ends of the U-shaped sliding frame 81 slide in cooperation with the limiting column 34, thereby causing the U-shaped sliding frame 81 to drive the L-shaped connecting frame 91 to move on the side of the workpiece tray 4. By utilizing the unidirectional movement cooperation between the L-shaped connecting frame 91 and the workpiece tray 4, the workpiece tray 4 is moved forward a certain distance, thereby realizing the automatic replacement of the workpiece tray 4 and improving the replacement efficiency of the workpiece tray 4.

[0067] In this embodiment, please refer to Figure 13-20 The side of the horizontal sliding frame 6 is also movably connected to a lifting assembly 63, and the side of the lifting assembly 63 is fixedly connected to a rotating terminal 64. The rotating terminal 64 can be moved up and down by the lifting assembly 63 to pick up and place the workpiece, thereby preventing the bottom of the workpiece from colliding with other positions when the workpiece is moved. The top of the rotating terminal 64 is also fixedly connected to a gripping claw 7.

[0068] The gripping claw 7 includes an extension shaft 712, with a flange 713 and a triangular seat 711 welded to both ends of the extension shaft 712. The flange 713 is fixedly connected to the bottom of the rotating terminal 64, while the outer side of the triangular seat 711 is provided with telescopic grooves 714 in a ring array.

[0069] Furthermore, each of the telescopic slides 714 is integrally provided with an air passage pipe 716, and positioning grooves 715 are provided on both sides of the telescopic slide 714. Moreover, a movable slide block 72 is movably connected to the inner side of the telescopic slide 714.

[0070] The movable slide 72 has a telescopic slide 721 inserted into the inside of the telescopic slide groove 714. The end of the telescopic slide 721 is also provided with a pneumatic cavity 723 corresponding to the air passage 716. The end of the air passage 716 is inserted into the inside of the pneumatic cavity 723, and the air passage 716 and the inside of the pneumatic cavity 723 are interconnected. At the same time, a sealing ring is embedded between the air passage 716 and the pneumatic cavity 723.

[0071] Furthermore, the telescopic slide 721 has load-bearing grooves 722 on both sides, and a dovetail groove 724 on the bottom of the telescopic slide 721. The bottom of the telescopic slide 721 is movably connected to an adaptive clamping claw 73 through the dovetail groove 724.

[0072] The adaptive clamping claw 73 has a dovetail slide rail 733 inserted into the inside of the dovetail slide groove 724, and the bottom of the dovetail slide rail 733 is integrally provided with a clamping plate 731. One end of the clamping plate 731 is also threaded with a locking screw 734, and the end of the locking screw 734 passes through the clamping plate 731 and the dovetail slide rail 733 and extends to the inside of the dovetail slide groove 724.

[0073] Furthermore, the clamping plate 731 has an integrally mounted mounting shaft 732 on its side bottom, and the clamping plate 731 is movably connected to a connecting bushing 736 via the mounting shaft 732. The connecting bushing 736 is integrally mounted with a swing clamping frame 735 on the side away from the clamping plate 731, and both ends of the swing clamping frame 735 are fixedly connected with positioning top rods 737.

[0074] By adopting the above technical solution, the lifting assembly 63 pushes the rotating terminal 64 downward, and the gripping claws 7 at the bottom of the rotating terminal 64 grip the workpiece. At this time, the swing clamping frame 735 is arranged in a rectangular array on the outside of the irregularly shaped workpiece. Then, by using the cooperation of the external air pump and air pipe, the air inside the air passage 716 and the pneumatic cavity 723 is collected to form a negative pressure, thereby causing the telescopic slide 721 to drive the clamping plate 731 to move closer to the workpiece surface. In addition, the clamping plate 731 will also drive the swing clamping frame 735 to move. The positioning rods 737 at both ends of the swing clamp 735 contact the workpiece surface one after another. Through the rotational engagement between the mounting shaft 732 and the connecting bushing 736, it is ensured that the positioning rods 737 at both ends are in contact with the workpiece surface. The workpiece is clamped by multiple positioning rods 737, and the three air ducts 716 are interconnected to ensure that the clamping assembly can automatically adjust the relative position between the movable slide 72 and the connecting hanger 71 according to the shape of the workpiece. Moreover, the use of compressed air for operation improves the response speed during clamping, thereby improving the clamping efficiency.

[0075] Furthermore, the side of the extension shaft 712 is also provided with an air pump connection hole 717. The inner sides of the three air pipes 716 are all connected to the inner side of the air pump connection hole 717. By connecting one end of the air pipe to the air pump connection hole 717, the external air pump can draw air from the inside of the air pipe 716 through the air pipe, so that the inside of the air pipe 716 forms a negative pressure, thereby driving the movable slide 72 in a ring array to retract inward and clamp the irregular workpiece. Conversely, by sending air to the inside of the air pipe 716, the movable slide 72 in a ring array can be pushed to expand outward, thereby releasing the irregular workpiece.

[0076] More specifically, the workpiece processing equipment 1 is also movably connected to a workpiece processing table 10, and the workpiece processing table 10 is located below one end of the linear module 5.

[0077] The linear module 5 is mainly composed of a linear guide body and a slider. The linear guide body and the slider are in sliding fit, and an adjusting screw is rotatably fitted on the inner side of the linear guide body. The adjusting screw is threadedly fitted with the slider. The motor at the end of the linear guide body drives the adjusting screw to rotate. Through the threaded fit between the adjusting screw and the slider, the slider moves laterally on the outer side of the linear guide body.

[0078] The linear guide body is fixedly connected to the extension mounting bracket 33, while the transverse sliding bracket 6 is fixedly connected to the slider, thereby moving the irregular workpiece from above the workpiece placement bracket 41 to the workpiece processing table 10.

[0079] Furthermore, the upper surface of the workpiece conveyor 2 is parallel to the pallet support plate 11. When the workpiece conveyor 2 moves the workpiece pallet 4, it can move the workpiece pallet 4 directly above the pallet support plate 11. The ends of the limiting protrusion 111 and the side baffle 112 are chamfered, which can make the workpiece pallet 4 move more smoothly above the pallet support plate 11.

[0080] By adopting the above technical solution, firstly, the linear module 5 drives the transverse sliding frame 6 to move laterally, causing the gripping claw 7 below the transverse sliding frame 6 to move above the irregularly shaped workpiece. Then, the gripping claw 7 below the transverse sliding frame 6 clamps the workpiece. The linear module 5 then drives the transverse sliding frame 6 to move in the opposite direction, moving the irregularly shaped workpiece above the workpiece processing table 10 in the workpiece processing equipment 1, and placing the workpiece on the workpiece processing table 10. As the linear module 5 moves back and forth, the irregularly shaped workpieces are loaded one by one. When all the irregularly shaped workpieces arranged laterally on the workpiece tray 4 have been picked up, and the transverse sliding frame 6 continues to move closer to the workpiece after placing the workpiece, the linear module 5 continues to move closer to the workpiece. When the workpiece processing equipment 1 moves a certain distance to one side, it will also move a certain distance away from the workpiece processing equipment 1 during the no-load return trip. Then, it will clamp the workpiece on the workpiece tray 4. When the contact rollers 62 at both ends of the moving push rod 61 contact the forward triangular top plate 83 or the reverse triangular top plate 84, the inclined surfaces of the forward triangular top plate 83 and the reverse triangular top plate 84 will cause the moving push rod 61 to push the U-shaped sliding frame 81 to move back and forth. Then, the workpiece tray 4 will be automatically advanced by the push of the feed extension frame 9, and the workpiece tray 4 that is no longer in use will be pushed out, ensuring continuous feeding during continuous processing. It can also realize the automatic replacement of the workpiece tray 4, thereby improving the feeding efficiency.

Those skilled in the art can easily understand the spirit of this invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of this invention, they are all within the protection scope of this invention.
