Description

Technical Field

[0001] This invention belongs to the field of automated processing, and specifically relates to an automated workpiece positioning and processing device. Background Technology

[0002] CNC automated production typically includes processes such as workpiece loading, processing, and unloading. To ensure processing stability, a positioning structure is usually set up in the processing process to fix the workpiece. The traditional positioning method is achieved by a fixture, which moves under the drive of a cylinder or motor to clamp or release the workpiece.

[0003] However, such positioning fixtures can generally only clamp and fix the workpiece in one direction, but the workpiece often needs to be processed from multiple directions or multiple positions. This positioning method makes it difficult to ensure that the workpiece remains fixed during the processing, which will affect the processing quality of the workpiece and thus affect the yield rate of the workpiece. Summary of the Invention

[0004] To address the aforementioned problems, the present invention aims to provide an automated workpiece positioning and processing device that can position the workpiece from multiple directions, ensuring the structural stability of the workpiece, thereby improving processing quality and increasing the yield of the workpiece.

The first hinge protrusion is hinged to the output shaft of the Z-axis positioning cylinder through a rotating shaft, and the second hinge protrusion is hinged to the pressure plate hinge base through a rotating shaft. This allows the output shaft of the Z-axis positioning cylinder to drive the Z-axis elastic pressure plate to rotate around the pressure plate hinge base as the axis, moving closer to or away from the positioning groove.

[0042] Furthermore, the Z-axis elastic pressure plate includes:

[0043] Pressure plate body;

[0045] The spring plate is located below the pressure plate body, and one end of the spring plate is integrally formed with the pressure plate body, while the other end of the spring plate has a gap with the pressure plate body for the spring plate to deform.

[0046] Furthermore, the bottom of the spring plate is provided with a machining positioning surface adapted to the shape of the workpiece, and both the pressure plate body and the spring plate are provided with contour grooves adapted to the shape of the workpiece. The design of the machining positioning surface enables the spring plate and the workpiece to be positioned well, and the design of the contour grooves avoids the machining position of the workpiece, making it convenient for the machining spindle to pass through the Z-axis elastic pressure plate to machine the workpiece.

[0047] Furthermore, the pressure plate body is provided with a protruding strip on the side near the spring plate. The protruding strip is located in the gap and can resist the spring plate to a certain extent when the spring plate deforms into the gap, thereby preventing the spring plate from deforming too much.

[0048] Furthermore, the convex strips are arranged at intervals along the X-axis or Y-axis direction.

[0059] Furthermore, drainage channels for water and chip removal are provided on the bottom walls of the first support groove, the second support groove, and the clearance groove. This allows water and processing waste chips to be discharged from the workpiece mounting groove.

[0060] Furthermore, the hopper also includes:

[0061] A positioning structure used to position the base and the tray;

[0062] And a fixing structure for securing the base and the tray.

[0063] Furthermore, the positioning structure includes:

[0065] And a second magnetic member capable of magnetically attracting the first magnetic member;

[0066] The base has a first groove on the side near the tray, and the first magnetic component is installed in the first groove. The tray has a second groove on the side near the base, and the second magnetic component is installed in the second groove. The first magnetic component and the second magnetic component are arranged vertically opposite each other.

[0067] Furthermore, the fixing structure includes:

[0068] Fixing pin;

[0069] And a retaining bushing that mates with the retaining pin;

[0070] The base has a first mounting hole on the side near the tray, and the tray has a second mounting hole on the side near the base. The fixing bushing is installed in the second mounting hole, and the lower end of the fixing pin is inserted into the first mounting hole, while the upper end of the fixing pin is inserted into the fixing bushing. After the tray and the base are aligned using the positioning structure, the fixing pin can be inserted into the fixing bushing of the tray to achieve positioning between them.

[0076] Furthermore, the first support plate has a first through hole that is vertically opposite to the drain channel, and the second support plate has a second through hole that is vertically opposite to the first through hole. In this application, water and processing debris in the workpiece mounting groove can enter the first through hole through the drain channel and then be discharged into the second through hole, thereby preventing water and processing debris from accumulating on the base.

[0077] Furthermore, the first through hole is a round hole, and the second through hole is an elongated hole.

[0078] Furthermore, the material transfer mechanism includes:

[0079] Material transfer mounting base;

[0080] Material handling gripper module;

[0081] Elastic ejector assembly for positioning workpieces;

[0082] The material handling gripper module and the elastic ejector assembly are both mounted on the material transfer mounting base, and the material handling gripper module is located on the side of the contour jig.

[0083] Furthermore, the material handling gripper module includes:

[0084] Gripper cylinder;

[0085] Material handling grippers;

[0086] The material handling gripper is connected to the output end of the gripper cylinder.

[0087] Furthermore, the elastic top material assembly includes:

[0088] Top material column;

[0089] Top spring;

[0090] The material transfer mounting base is provided with a spring movable groove, and a through hole is opened on the bottom wall of the spring movable groove.

The upper end of the tube is connected to the movable groove, and the lower end of the tube extends into the material handling gripper. When the ejector column performs the ejection operation, external compressed air passes through the gas channel and the spring movable groove, enters the tube from the upper end, and then exits from the lower end, thereby cleaning and removing debris from the workpiece.

[0114] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0115] To achieve the above objectives, the technical solution of the present invention is as follows:

[0116] See Figure 1 As shown, this embodiment provides an automated workpiece positioning and processing device, including:

[0117] Processing platform 1;

[0118] Storage bin 2 is used to store workpiece A;

[0119] Positioning mechanism 3 is used to position workpiece A;

[0120] Material handling mechanism 4 for picking up and placing workpiece A;

[0121] And the machining spindle 5 used to process workpiece A;

[0122] See Figure 2-9 The positioning mechanism 3 includes:

[0123] Positioning support plate 31;

[0124] A contour jig 32 for accommodating workpiece A;

[0125] And a positioning component capable of positioning workpiece A from multiple directions;

[0126] The positioning support plate 31 is installed on the processing platform 1. The contour jig 32 and the positioning structure are both installed on the positioning support plate 31. The positioning structure is arranged opposite to the contour jig 32. The hopper 2 and the material transfer mechanism 4 are arranged on the side of the contour jig 32. The processing spindle 5 is located above the contour jig 32.

[0127] The processing flow of this processing device is as follows:

[0128] S1: The workpiece A to be processed is placed manually into the hopper 2;

[0129] S2: The material transfer mechanism 4 clamps the workpiece A, places the workpiece A on the contour jig 32 of the positioning mechanism 3, and fixes it in place by the positioning structure;

[0130] S3: Machining spindle 5 processes workpiece A on the copying fixture 32;

[0131] S4: After processing is completed, the material transfer mechanism 4 removes the workpiece A from the copying fixture 32 and places it in the material bin 2;

[0132] S5: Manually remove all processed workpieces A from hopper 2, and then replace them with workpieces A to be processed, thus achieving cyclical automated production.

[0133] With the above settings, the automated loading, unloading, positioning and processing of workpiece A can be realized, which can improve processing efficiency. At the same time, the shape of the profiling fixture 32 is adapted to the shape of workpiece A. With the help of the positioning structure, workpiece A can be positioned from multiple directions to ensure the structural stability of workpiece A, thereby improving the processing quality and increasing the yield of workpiece A.

[0134] Furthermore, the positioning component includes:

[0135] An X-axis positioning module 33 capable of positioning a workpiece in the X-axis direction;

[0136] Y-axis positioning module 34, capable of positioning a workpiece in the Y-axis direction;

[0137] Z-axis positioning module 35, capable of positioning a workpiece in the Z-axis direction;

[0138] The contour jig 32 is provided with a positioning groove 321 for accommodating the workpiece. The X-axis positioning module 33 is disposed opposite to the positioning groove 321 in the X-axis direction, the Y-axis positioning module 34 is disposed opposite to the positioning groove 321 in the Y-axis direction, and the Z-axis positioning module 35 is disposed opposite to the positioning groove 321 in the Z-axis direction.

[0139] Furthermore, the positioning groove 321 is a groove with openings on one side in the X-axis, Y-axis, and Z-axis directions. The X-axis positioning module 33, Y-axis positioning module 34, and Z-axis positioning module 35 can enter the positioning groove 321 from the openings on one side of the X-axis, Y-axis, and Z-axis respectively, and cooperate with the inner wall on the other side of the positioning groove 321 to clamp the workpiece in the positioning groove 321, thereby achieving the positioning of the workpiece in the X-axis, Y-axis, and Z-axis directions.

[0140] Furthermore, the X-axis positioning module 33 includes:

[0141] X-axis piston 331;

[0142] X-axis piston rod 332;

[0143] X-axis positioning block 333;

[0144] The positioning support plate 31 has an installation groove 311, the contour jig 32 is fixed in the installation groove 311, the contour jig 32 has a piston cavity 322 in the X-axis direction, the X-axis piston 331 is movably disposed in the piston cavity 322, the X-axis positioning block 333 is located outside the piston cavity 322, the X-axis piston 331 and the X-axis positioning block 333 are connected by the X-axis piston rod 332, and the X-axis positioning block 333 is disposed in the X-axis direction of the positioning groove 321;

[0145] The contour jig 32 is provided with an air inlet 323 and an air outlet 324 that communicate with the piston chamber 322. The air inlet 323 and the air outlet 324 are located on opposite sides of the X-axis piston 331 in the X-axis direction.

[0146] In this application, an external air source can be introduced into the piston chamber 322 through the air inlet 323 and air outlet 324 to form a cylinder-type structure, which drives the X-axis piston 331 to move within the piston chamber 322. The X-axis piston rod 332 drives the X-axis positioning block 333 to move in the X-axis direction, so that the X-axis positioning block 333 moves closer to or further away from the workpiece in the positioning groove 321, thereby clamping or releasing the workpiece in the X-axis direction. The above structure integrates the cylinder of the X-axis positioning module 33 onto the contour jig 32, making the overall structure more compact. Compared with a separate cylinder, it saves space and simplifies the device structure.

[0147] Furthermore, the Y-axis positioning module 34 includes:

[0148] Y-axis positioning cylinder 341;

[0149] First oblique cutting push block 342;

[0150] Second oblique cutting push block 343;

[0151] Y-axis positioning block 344;

[0152] The Y-axis positioning cylinder 341 is fixed on the positioning support plate 31, and the first oblique push block 342 is connected to the output end of the Y-axis positioning cylinder 341. The positioning support plate 31 is provided with a movable groove, and the second oblique push block 343 and the Y-axis positioning block 344 are both movably disposed in the movable groove. One end of the Y-axis positioning block 344 is fixedly installed on the second oblique push block 343, and the other end is disposed opposite to the positioning groove 321 in the Y-axis direction. The second oblique push block 343 and the first oblique push block 342 are engaged by an oblique surface, so that the first oblique push block 342 can push the second oblique push block 343 and the Y-axis positioning block 344 to move towards the side closer to the positioning groove 321 in the Y-axis direction under the drive of the Y-axis positioning cylinder 341.

[0153] In this application, when the output shaft of the Y-axis positioning cylinder 341 extends, it can push the first oblique push block 342 to move. The first oblique push block 342 pushes the second oblique push block 343 to move in the Y-axis direction through the oblique surface cooperation, thereby driving the Y-axis positioning block 344 to approach the positioning groove 321 and fix the workpiece in the positioning groove 321 in the Y-axis direction. When it is necessary to pick up or put down the workpiece, when the output shaft of the Y-axis positioning cylinder 341 retracts, it can push the Y-axis positioning block 344 away from the positioning groove 321 by means of elastic reset, etc., and release the workpiece.

[0154] Furthermore, the first oblique-cutting push block 342 has a first oblique surface 345, and the second oblique-cutting push block 343 has a second oblique surface 346 with the same inclination as the first oblique surface 345, and the first oblique surface 345 and the second oblique surface 346 are in contact with each other.

[0155] Furthermore, the Y-axis positioning cylinder 341 is located below the positioning support plate 31, and the second oblique-cutting push block 343 is located above the positioning support plate 31. The positioning support plate 31 has a through hole to allow the first oblique-cutting push block 342 to move up and down. In this application, since the Z-axis positioning module 35 needs to position the workpiece in the positioning groove 321 from top to bottom, it must be located above the positioning support plate 31. Based on this, in order to make the entire positioning structure reasonably integrated on the positioning support plate 31, the preferred method is to place the Y-axis positioning module 34 below the positioning support plate 31. The through hole in the positioning support plate 31 is to avoid structural interference between the positioning support plate 31 and the movement of the second oblique-cutting push block 343.

[0156] Furthermore, the Z-axis positioning module 35 includes:

[0157] Z-axis positioning cylinder 351;

[0158] Z-axis elastic pressure plate 352;

[0159] Pressure plate hinged base 353;

[0160] The Z-axis positioning cylinder 351 and the pressure plate hinge base 353 are both fixedly installed on the positioning support plate 31. The Z-axis elastic pressure plate 352 and the positioning groove 321 are arranged opposite to each other in the Z-axis direction. The Z-axis elastic pressure plate 352 has a first hinge protrusion 3521 and a second hinge protrusion 3522. The first hinge protrusion 3521 is hinged to the output shaft of the Z-axis positioning cylinder 351 through a rotating shaft. The second hinge protrusion 3522 is hinged to the pressure plate hinge base 353 through a rotating shaft. This allows the output shaft of the Z-axis positioning cylinder 351 to drive the Z-axis elastic pressure plate 352 to rotate around the pressure plate hinge base 353 as the axis, moving closer to or away from the positioning groove 321.

[0161] Through the above structural design, the Z-axis elastic pressure plate 352 can achieve the clamping and positioning of the workpiece in the Z-axis direction by flipping. It has the characteristics of structural stability and does not occupy the space above the workpiece when releasing the workpiece, which facilitates the material transfer mechanism 4 to pick up and put down the workpiece.

[0162] Furthermore, the Z-axis elastic pressure plate 352 includes:

[0163] Pressure plate body 3523;

[0164] Spring plate 3524;

[0165] The spring plate 3524 is located below the pressure plate body 3523, and one end of the spring plate 3524 is integrally formed with the pressure plate body 3523. The other end of the spring plate 3524 and the pressure plate body 3523 have a gap 3525 for the spring plate 3524 to deform and move.

[0166] In this application, the Z-axis elastic pressure plate 352 moves in conjunction with components such as the cylinder and the base. Due to the manufacturing tolerances of the cylinder, the base, and the Z-axis elastic pressure plate 352 itself, the contact between the Z-axis elastic pressure plate 352 and the workpiece cannot be perfectly matched. When the two are relatively loose, the Z-axis elastic pressure plate 352 cannot fully fit with the workpiece and cannot firmly press the product; when the two are too close, the Z-axis elastic pressure plate 352 may crush the workpiece. This application creates a slot at the bottom of the Z-axis elastic pressure plate 352, forming a deformable spring plate 3524 at the bottom. The slot provides a deformable space for the spring plate 3524, allowing for a tighter fit between the Z-axis elastic pressure plate 352 and the workpiece. When pressing the product, the deformation of the spring plate 3524 enables it to make good surface contact with the workpiece, resulting in better fit. In addition, the deformation design also allows for soft contact between the spring plate 3524 and the workpiece, thus preventing the Z-axis elastic pressure plate 352 from damaging the workpiece.

[0167] Furthermore, the bottom of the spring plate 3524 is provided with a machining positioning surface 3526 adapted to the shape of the workpiece, and both the pressure plate body 3523 and the spring plate 3524 are provided with contour grooves 3527 adapted to the shape of the workpiece. The design of the machining positioning surface 3526 enables the spring plate 3524 to be well positioned with the workpiece, and the design of the contour grooves 3527 avoids the machining position of the workpiece, facilitating the machining spindle 5 to pass through the Z-axis elastic pressure plate 352 to machine the workpiece.

[0168] Furthermore, the pressure plate body 3523 is provided with a protrusion 3528 on the side near the spring plate 3524. The protrusion 3528 is located in the gap 3525 and can resist the spring plate 3524 to a certain extent when the spring plate 3524 deforms into the gap 3525, thereby preventing the spring plate 3524 from deforming too much.

[0169] Furthermore, the protrusions 3528 are arranged at intervals along the X-axis or Y-axis direction.

[0170] Further, see Figures 12-16 The hopper 2 includes:

[0171] Tray 21 for storing workpieces;

[0172] and a base 22 for supporting the tray 21;

[0173] The material tray 21 is mounted on the base 22, and the base 22 is mounted on the processing platform 1;

[0174] The material tray 21 has one or more workpiece mounting slots 23, and the workpiece mounting slots 23 include:

[0175] First support groove 231;

[0176] 232 air gap;

[0177] And the second support groove 233;

[0178] The first support groove 231 and the second support groove 233 are symmetrically arranged on opposite sides of the clearance groove 232.

[0179] In this application, the clearance groove 232 enables the middle part of the workpiece to be suspended, which facilitates the heat dissipation of the workpiece. The first support groove 231 and the second support groove 233 are symmetrically arranged, which enables the workpiece to be installed without error.

[0180] Furthermore, the clearance groove 232 is provided with a support protrusion 24 for supporting the workpiece. This can support the workpiece and improve structural stability.

[0181] Furthermore, drainage channels 234 for draining water and removing chips are provided on the bottom walls of the first support groove 231, the second support groove 233, and the clearance groove 232. This allows water and processing waste chips generated in the workpiece mounting groove 23 to be discharged.

[0182] Furthermore, the hopper 2 also includes:

[0183] Positioning structure 25 used to position the base 22 and the tray 21;

[0184] And a fixing structure 26 for fixing the base 22 and the tray 21.

[0185] In this application, when the tray 21 is installed on the base 22, the positions of the two are first aligned by the positioning structure 25, and then the two are fixed together by the fixing structure 26, which can not only facilitate the installation of the two, but also improve the structural stability of the two.

[0186] Furthermore, the positioning structure 25 includes:

[0187] First magnetic accumulator 251;

[0188] And a second magnetic member 252 that can be magnetically attracted to the first magnetic member 251;

[0189] The base 22 has a first groove 221 on the side near the tray 21, and the first magnetic member 251 is installed in the first groove 221. The tray 21 has a second groove 211 on the side near the base 22, and the second magnetic member 252 is installed in the second groove 211. The first magnetic member 251 and the second magnetic member 252 are arranged vertically opposite each other.

[0190] In this application, when the tray 21 is installed on the base 22, the positions of the two can be aligned by the magnetic attraction of the first magnetic member 251 and the second magnetic member 252, thereby facilitating the fixation between the two.

[0191] Furthermore, the fixing structure 26 includes:

[0192] Fixing pin 261;

[0193] and a fixing bushing 262 that cooperates with the fixing pin 261;

[0194] The base 22 has a first mounting hole 222 on the side near the tray 21, and the tray 21 has a second mounting hole 212 on the side near the base 22. The fixing bushing 262 is installed in the second mounting hole 212, and the lower end of the fixing pin 261 is inserted into the first mounting hole 222, while the upper end of the fixing pin 261 is inserted into the fixing bushing 262. After the tray 21 and the base 22 are aligned using the positioning structure 25, the fixing pin 261 can be inserted into the fixing bushing 262 of the tray 21, thus achieving positioning between them.

[0195] Furthermore, the base 22 includes:

[0196] First support plate 223;

[0197] More than one support column 224;

[0198] And the second support plate 225;

[0199] The top surface of the first support plate 223 is connected to the material tray 21 through the positioning structure 25 and the fixing structure 26, and the bottom surface of the first support plate 223 is connected to the second support plate 225 through the support column 224.

[0200] In this application, the first support plate 223 directly supports the material tray 21, and the second support plate 225 serves as the support base plate of the base 22. The material tray 21 is supported to a certain height by the support column 224, which facilitates the picking and placing of workpieces.

[0201] Furthermore, the first support plate 223 has a first through hole 226 that is vertically opposite to the drain channel 234, and the second support plate 225 has a second through hole 227 that is vertically opposite to the first through hole 226. In this application, water and processing waste in the workpiece mounting groove can enter the first through hole 226 through the drain channel 234 and then be discharged into the second through hole 227, thereby preventing water and processing waste from accumulating on the base 22.

[0202] Furthermore, the first through hole 226 is a round hole, and the second through hole 227 is an elongated hole.

[0203] Further, see Figure 10-11 The material transfer mechanism 4 includes:

[0204] Material transfer mounting base 41;

[0205] Material handling gripper module 42;

[0206] Elastic ejector assembly 43 for positioning workpiece;

[0207] The material handling gripper module 42 and the elastic ejector assembly 43 are both mounted on the material transfer mounting base 41, and the material handling gripper module 42 is located on the side of the contour jig 32.

[0208] In this application, the gripper module 42 can pick up and put down workpieces by gripping. During the pick-up and put-down operation, the elastic top material component 43 can position the workpiece, so that the gripper module 42 can easily and stably grip the workpiece.

[0209] Furthermore, the material handling gripper module 42 includes:

[0210] Gripper cylinder 421;

[0211] Material handling gripper 422;

[0212] The material handling gripper 422 is connected to the output end of the gripper cylinder 421.

[0213] Furthermore, the elastic top material assembly 43 includes:

[0214] Top material column 431;

[0215] Top spring 432;

[0216] The material transfer mounting base 41 is provided with a spring movable groove 411. A through hole 412 is opened on the bottom wall of the spring movable groove 411. The top material spring 432 is disposed in the spring movable groove 411. The top material column 431 moves up and down through the through hole 412. The upper end of the top material column 431 enters the spring movable groove 411 and abuts or connects with the top material spring 432. The lower end of the top material column 431 extends into the material picking claw 422.

[0217] In the prior art, it is known that the material handling gripper 422 is composed of two grippers. The gripping or releasing of the workpiece is achieved by opening and closing the two grippers. Based on this, during the ejection operation, the ejector column 431 is inserted between the two grippers to position the workpiece, ensuring the balance of the workpiece and improving the stability of the material handling gripper 422 module 42 in gripping the material. The elastic ejector component 43 of this application is based on this principle. The entire ejector column 431 is vertically arranged between the two grippers of the material handling gripper 422. Its upper end is connected to the transfer mounting base 41 through the ejector spring 432 to ensure that its lower end can elastically extend and retract. During ejection, the lower end of the ejector column 431 contacts the workpiece, and the workpiece is pressed and positioned by elastic buffering, ensuring the balance and stability of the workpiece when gripping it.

[0218] Furthermore, the material transfer mounting base 41 is also provided with a gas channel 413. One end of the gas channel 413 is connected to an external air source, and the other end is connected to a spring movable groove 411. The top material column 431 is a tube with openings at both the top and bottom. The upper end of the tube is connected to the movable groove, and the lower end of the tube extends into the material picking gripper 422. When the top material column 431 is performing the material lifting operation, external compressed air passes through the gas channel 413 and the spring movable groove 411, enters the tube from the upper end, and then blows out from the lower end, thereby cleaning and removing debris from the workpiece.

[0219] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
