DETAILED DESCRIPTION

[0032] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0033] The following describes the workpiece processing device 100 according to the present application with reference to the drawings.

[0034] like Figures 1 to 3 As shown, a workpiece processing device 100 is provided in a specific embodiment of the present application, and the workpiece processing device 100 includes a processing table 3 and a clamping assembly 4, wherein the processing table 3 is formed with a workpiece processing position 31, and a plurality of pressure detection components 2 are arranged in the workpiece processing position 31; the clamping assembly 4 includes a driving member 41 and a plurality of workpiece clamping members 42, the plurality of workpiece clamping members 42 are clamped and matched with the workpiece processing position 31, the plurality of workpiece clamping members 42 are arranged one by one with the plurality of pressure detection components 2, and the driving member 41 can adjust the clamping force of the workpiece clamping member 42 on the workpiece.

[0035] For CNC machining of large quantities of workpieces, clamping and fixing are generally used to position the workpieces. However, the size of the clamping force applied to the workpiece by the clamping tool is often judged by the experience of the technicians. Although the technicians are experienced, there are also cases where the judgment is inaccurate. Once the judgment is inaccurate, it will cause adverse effects. For example, excessive pressure causes the workpiece to deform and increase the defective rate of workpiece processing, and too little pressure causes the workpiece product to shift or tilt, affecting the efficiency of workpiece processing. In other words, providing a suitable clamping force when positioning the workpiece is beneficial to improving the quality and efficiency of workpiece processing. In a specific embodiment of the present application, the workpiece to be processed is placed on the workpiece processing position 31 of the processing table 3, and the workpiece is clamped and fixed by the driving member 41 to drive the workpiece clamping member 42 to press and cooperate with the processing table 3. At the same time, the pressure detection member 2 set on the workpiece processing position 31 is used to detect the clamping force of the workpiece clamping member 42 on the workpiece during the clamping process, so that the technician can adjust the driving force of the driving member 41 in time according to the size of the clamping force, and then provide a suitable clamping force for the workpiece to avoid abnormal situations such as workpiece deformation or workpiece tilting.

[0036] Specifically, the driving member 41 drives the workpiece clamping member 42 to be pressed together with the workpiece processing position 31 of the processing table 3, wherein the driving member 41 provides a driving force, and the workpiece clamping member 42 is acted upon by the driving force to provide a clamping force to the workpiece, and the workpiece is acted upon by the clamping force of the workpiece clamping member 42 to apply pressure to the pressure detection member 2 on the workpiece processing position 31.

[0037] It should be noted that the workpiece processing device 100 provided in the specific embodiment of the present application is mainly used in a computer numerical control machine tool (CNC), which can logically process a program specified by a control code or other symbolic instructions and enable the machine tool to execute the actions specified by the program, for example, by cutting a blank into a semi-finished product or a finished part, and the workpiece processing device 100 is also controlled by a computer to clamp and fix the blank to complete the subsequent tool cutting process. In other words, the workpiece in the specific embodiment of the present application refers to the blank, and the workpiece processing process refers to the tool cutting the blank to form a semi-finished product or a finished part. It can be understood by those skilled in the art that the above-mentioned workpiece can also be various semi-finished products, and the workpiece processing process can also refer to the tool cutting the semi-finished product to form a finished part, or it can be other various types of processing processes that need to be performed using a computer numerical control machine tool. In the specific embodiment of the present application, the processing of the blank is used as an example for explanation, but it does not limit the scope of protection of the present application.

[0038] It is also necessary to further explain that, since the workpiece needs to be placed on the workpiece processing position 31, the workpiece in the present application needs to have a plane reference, and this plane reference is used to contact with the workpiece processing position 31 for plane positioning. In other words, the workpiece processing device 100 provided in the specific embodiment of the present application is mainly used for CNC tool cutting of a large number of blanks whose bottom or side references are planes.

[0039] Since it is applied to computer numerical control machine tools, in some embodiments, the workpiece processing device 100 also includes a control unit connected to the computer for communication, the control unit is electrically connected to the pressure detection component 2 and the driving component 41, and the control unit is configured to adjust the clamping force of the workpiece clamping component 42 on the workpiece according to the pressure of the workpiece detected by the pressure detection component 2.

[0040] In fact, the control unit directly adjusts the driving force of the driving member 41 according to the pressure detected by the pressure detection member 2, thereby indirectly adjusting the clamping force of the workpiece clamping member 42. Before starting the driving member 41, the technician needs to determine the preset pressure of the workpiece according to the physical properties, specification parameters and other factors of the workpiece; in the process of the driving member 41 driving the workpiece clamping member 42 and the workpiece processing position 31 to clamp the workpiece, when the pressure detected by the pressure detection member 2 reaches the preset pressure, the control unit enables the driving member 41 to maintain the current driving force until the processing is completed; after the processing is completed, the control unit enables the driving member 41 to reduce the driving force and release the space between the workpiece clamping member 42 and the workpiece processing position 31, so as to facilitate the transfer of the processed workpiece to the next process.

[0041] In addition to the control unit controlling the driving member 41 to drive the workpiece clamping member 42 to gradually clamp the workpiece, another control method can be selected, that is, directly converting the preset pressure of the workpiece into the preset driving force of the driving member 41, and directly controlling the driving member 41 through the control unit to provide the preset driving force to the workpiece clamping member 42. It can be seen that the entire processing flow is set and executed by the control unit, thereby reducing the labor intensity of technicians and improving the processing efficiency of the workpiece.

[0042] It should be noted that the pressure detection component 2 can be made of various force sensors, and the structures and principles of the force sensors and control units are well known to those skilled in the art, and are not the core improvement points of the present application, and will not be elaborated here.

[0043] Unless otherwise specified, the directional words such as "up, down, left, right, front, and back" used in the specific embodiments of the present application are generally relative to the directions shown in the drawings. The position descriptor "inside" used refers to the interior of a component or space, and the position descriptor "outside" used refers to the exterior of a component or space.

[0044] Based on the direction regulations, the present application provides an exemplary embodiment to illustrate a workpiece processing device 100, wherein a processing table 3 is located on a processing horizontal plane, a workpiece processing position 31 is provided on the upper end surface of the processing table 3, a plane reference of the workpiece to be processed is parallel to the bottom surface of the workpiece processing position 31, a clamping assembly 4 is arranged above the workpiece processing position 31, and a driving member 41 drives the workpiece clamping member 42 to move in the up and down directions.

[0045] In some embodiments, the workpiece processing position 31 is a groove structure opened on the upper end surface of the processing table 3, and multiple pressure detection parts 2 are laid flat on the bottom of the groove structure. When the workpiece to be processed is transferred to the workpiece processing position 31, the groove structure is used to position the workpiece in the front-to-back direction and the left-to-right direction, and the workpiece clamping part 42 is clamped with the groove structure to limit the workpiece in the up and down direction, thereby realizing the positioning and fixation of the workpiece in space, thereby ensuring that the workpiece does not shift or warp during the processing to improve the processing efficiency.

[0046] Preferably, the number of driving members 41 is multiple and they are driven and arranged in a one-to-one correspondence with the multiple workpiece clamping members 42, that is, each workpiece clamping member 42 is driven independently by a corresponding driving member 41, and the multiple driving members 41 are arranged in parallel and spaced apart from each other, that is, each workpiece clamping member 42 can independently clamp the workpiece on the workpiece processing position 31 under the drive of the corresponding driving member 41. At the same time, the number of pressure detection members 2 in the workpiece processing position 31 is also multiple. In other words, the correspondingly arranged driving members 41, workpiece clamping members 42 and pressure detection members 2 are arranged in sequence from top to bottom. It can be seen that in the process of clamping the workpiece, the control unit can adjust the driving force of the aligned driving member 41 according to the pressure detected by each pressure detection member 2, thereby indirectly adjusting the clamping force of the aligned workpiece clamping member 42 on the workpiece, thereby improving the practicality of the workpiece processing device 100.

[0047] Furthermore, technicians can use the control unit to individually set the driving force of each driving member 41 according to different contact positions with the workpiece (such as thickness), thereby being suitable for products with various irregular flatnesses, thereby increasing the application range of the workpiece processing device 100.

[0048] Furthermore, the use of multiple driving members 41 and multiple workpiece clamping members 42 can also shape the workpiece during the clamping process, that is, clamp and adjust the workpiece that has slightly deformed during the previous processing process, thereby reducing the defective rate of the workpiece.

[0049] Of course, multiple workpiece clamping members 42 are driven and connected to the same driving member 41, and the pressure detection members 2 are arranged at several arrangement points in the workpiece processing position 31, which can also achieve the adjustment of the clamping force. This method also belongs to the protection scope of this application.

[0050] like Figure 4As shown, in some embodiments, the driving member 41 includes an electromagnet portion arranged in pairs, each pair of electromagnet portions includes a second electromagnet portion 412 connected to the workpiece clamping member 42 and a first electromagnet portion 411 arranged at intervals along the clamping direction with the second electromagnet portion 412, and the first electromagnet portion 411 and the second electromagnet portion 412 have the same magnetic pole.

[0051] Specifically, the first electromagnet portion 411 is located directly above the second electromagnet portion 412, the workpiece clamping member 42 is connected to the lower end surface of the second electromagnet portion 412 and the center lines coincide with each other, and the direction of the magnetic force generated by the first electromagnet portion 411 and the second electromagnet portion 412 is in the up and down direction, that is, the first electromagnet portion 411, the second electromagnet portion 412, the workpiece clamping member 42 and the pressure detection member 2 corresponding to the workpiece clamping member 42 are located on the same straight line extending in the up and down direction. In other words, the direction of action of the magnetic force is perpendicular to the detection surface of the pressure detection member 2, so that the pressure detected by the pressure detection member 2 can accurately feedback the driving force of the driving member 41, thereby improving the accuracy of adjusting the workpiece clamping force, and further improving the practicality of the workpiece processing device 100.

[0052] Furthermore, the first electromagnet part 411 and the second electromagnet part 412 are both electrically connected to the control unit, and the control unit is further configured to adjust the magnetic force between the first electromagnet part 411 and the second electromagnet part 412 according to the pressure of the workpiece detected by the pressure detection member 2. The working principle of the electromagnet is well known to those skilled in the art and will not be described in detail here. It is equivalent to that the control unit adjusts the current passed into the first electromagnet part 411 and / or the second electromagnet part 412.

[0053] In fact, the magnitude of the magnetic force can be adjusted by choosing to adjust the magnitude of the current passed through the first electromagnet part 411 or the second electromagnet part 412 separately, or by choosing to adjust the magnitude of the current passed through the first electromagnet part 411 and the second electromagnet part 412 at the same time. In addition, the direction of the magnetic force can be adjusted by adjusting the direction of the current passed through the first electromagnet part 411 or the second electromagnet part 412, thereby achieving the downward pressure and upward pressure of the workpiece clamping member 42, and then completing the clamping and release of the workpiece.

[0054] In order to limit the direction of the magnetic force, in some embodiments, the clamping assembly 4 also includes an electromagnetic bin 43, an electromagnetic cover plate 44 serving as a cover plate of the electromagnetic bin 43, and an electromagnetic bin cover 45 serving as a bottom plate of the electromagnetic bin 43, and the direction of the magnetic force is limited by the sliding cooperation between the bin wall of the electromagnetic bin 43 and the second electromagnet part 412.

[0055] Specifically, the electromagnetic cover 44 is located at the upper end of the electromagnetic bin 43, and the electromagnetic bin cover 45 is located at the lower end of the electromagnetic bin 43. A PLC module 48 electrically connected to the control unit is embedded in the electromagnetic cover 44. The PLC module 48 is electrically connected to the first electromagnet part 411 and the second electromagnet part 412 respectively. The first electromagnet part 411 is located in the electromagnetic bin 43 and is fixedly connected to the lower end surface of the electromagnetic cover 44. The second electromagnet part 412 passes through the electromagnetic bin cover 45. One end (upper end) of the second electromagnet part 412 located in the electromagnetic bin 43 slides with the inner side wall of the electromagnetic bin 43, and the other end (lower end) of the second electromagnet part 412 located outside the electromagnetic bin cover 45 is connected to the workpiece clamping member 42.

[0056] Furthermore, a limit block is formed at the upper end of the second electromagnet portion 412 to limit the electromagnetic chamber cover 45 along the up and down directions, thereby preventing the second electromagnet portion 412 from separating from the electromagnetic chamber 43, thereby improving the reliability of the workpiece processing device 100.

[0057] Those skilled in the art can understand that the workpiece clamping member 42 can be a block with any cross-sectional shape, preferably a square block; the first electromagnet part 411 and the second electromagnet part 412 can be cylinders with any cross-sectional shape, preferably a square cylinder; the cross-sectional size of the square block can be further preferably the same as the cross-sectional size of the square cylinder.

[0058] In the above-mentioned embodiment, the direction of the magnetic force is changed by switching the direction of the current to realize the downward pressing and upward lifting of the workpiece clamping member 42. In fact, it is also possible to choose to set a first spring 49 connected to the electromagnetic chamber cover 45 on the second electromagnet part 412, and use the restoring force of the first spring 49 to realize the upward lifting of the workpiece clamping member 42: when the workpiece clamping member 42 is pressed down, the first spring 49 is compressed at the same time. After the processing of the workpiece is completed, the current passing through the first electromagnet part 411 and the second electromagnet part 412 is directly cut off, and the second electromagnet part 412 is driven to move upward by the upward elastic force of the first spring 49, thereby driving the workpiece clamping member 42 to move upward to complete the release of the workpiece, thereby saving energy.

[0059] like Figure 5 and Figure 6 As shown, in some embodiments, the workpiece processing device 100 further includes a sliding track 5, and the clamping assembly 4 includes a sliding member 46 that slidably cooperates with the sliding track 5, and the sliding member 46 slidably cooperates with the sliding track 5 to allow the workpiece clamping member 42 to enter or leave the workpiece processing position 31. When the workpiece to be processed is placed in the workpiece processing position 31 or the workpiece that has been processed is moved out of the workpiece processing position 31, the workpiece clamping member 42 is moved out of the range of the workpiece processing position 31 by the sliding cooperation between the sliding member 46 and the sliding track 5, thereby facilitating the transfer of the workpiece and further improving the efficiency of workpiece processing.

[0060] As for the extension direction of the sliding track 5, it needs to be determined according to the specific transfer direction of the workpiece. In the exemplary embodiment of the present application, the processing table 3 is formed with a to-be-processed position 32 arranged on the upstream side of the workpiece processing position 31 along the workpiece transfer direction and a processed position 33 arranged on the downstream side along the workpiece transfer direction, wherein the workpiece transfer direction is the front-to-back direction, in other words, the to-be-processed position 32 is located at the front side of the workpiece processing position 31, and the processed position 33 is located at the rear side of the workpiece processing position 31, the to-be-processed position 32 is used to place the workpiece to be processed, and the processed position 33 is used to place the workpiece that has been processed.

[0061] Specifically, a placement area is provided between the to-be-processed position 32 and the workpiece processing position 31, and the sliding track 5 extends from the placement area to the workpiece processing position 31 along the front-to-back direction, and the sliding track 5 is located as a whole on the left or right side of the workpiece processing position 31. When the to-be-processed workpiece is placed in the workpiece processing position 31 or the processed workpiece is moved out of the workpiece processing position 31, the workpiece clamping member 42 slides forward to the placement area.

[0062] Similarly, a placement area may be provided between the processed position 33 and the workpiece processing position 31, and the sliding track 5 extends from the placement area to the workpiece processing position 31 along the front-rear direction, and the sliding track 5 is located on the right or left side of the workpiece processing position 31. When the workpiece to be processed is placed in the workpiece processing position 31 or the workpiece that has been processed is moved out of the workpiece processing position 31, the workpiece clamping member 42 slides backward to the placement area.

[0063] Those skilled in the art can understand that, in addition to setting the placement area on the front or rear side of the workpiece processing position 31, the placement area can also be set on the left or right side of the workpiece processing position 31. Correspondingly, the sliding rail 5 extends from the placement area to the workpiece processing position 31 along the left and right directions, and other implementations also fall within the scope of protection of the present application.

[0064] The sliding rail 5 extending along the front-to-back direction and being entirely located on the left side of the workpiece processing position 31 is used as an exemplary embodiment for explanation. In some embodiments, the sliding rail 5 includes a rail body 53 having a sliding groove 51 extending along the front-to-back direction, the notch of the sliding groove 51 faces right, the sliding member 46 is located in the sliding groove 51 and is provided with a connecting member 47 connected to the workpiece clamping member 42. The connection position between the workpiece clamping member 42 and the connecting member 47 is not limited, and the connecting member 47 can also be connected to the electromagnetic cover plate 44 to achieve an indirect connection with the workpiece clamping member 42.

[0065] Specifically, the sliding rail 5 also includes a plurality of support frames 54 arranged at intervals along the front-to-back direction. The plurality of support frames 54 are all located on the left side of the workpiece processing position 31 and are fixedly connected to the upper end surface of the processing table 3. A connecting groove 541 is provided on the support frame 54, and a plug-in block 531 is provided on the rail body 53 for plugging and cooperating with the connecting groove 541. It can be seen that the position of the connecting groove 541 along the up-down direction determines the position of the rail body 53 along the up-down direction. In other words, the position of the rail body 53 along the up-down direction can be adjusted by adjusting the position of the connecting groove 541 along the up-down direction, so that it is suitable for the installation of clamping assemblies 4 of different sizes.

[0066] Preferably, the sliding member 46 is an electric slider electrically connected to the control unit, and the control unit drives the electric slider to move to drive the workpiece clamping member 42 to move, thereby improving the automation level of the workpiece processing device 100 and further improving the efficiency of workpiece processing.

[0067] During the workpiece processing, cooling liquid is required to cool the processing area and waste powder will be generated. In some embodiments, a stopper 52 is provided on the rail body 53 for shielding the slot of the sliding slot 51, thereby effectively preventing waste powder and cooling liquid from splashing into the sliding slot 51, thereby avoiding affecting the sliding of the sliding member 46 to improve the reliability of the workpiece processing device 100.

[0068] Specifically, the stopper 52 is buckled on the slot of the sliding slot 51 and forms a through hole 521 which is consistent with the extension direction of the sliding slot 51 . The connecting member 47 passes through the through hole 521 and is connected to the electromagnetic cover plate 44 , thereby preventing the stopper 52 from affecting the sliding of the sliding member 46 .

[0069] Further, the stopper 52 includes an upper body part 523 and a lower body part 524 symmetrically arranged on the upper and lower sides of the track body 53, and the upper body part 523 and the lower body part 524 both extend in the front-to-back direction and have L-shaped cross sections. The upper body part 523 and the lower body part 524 each include two straight edges, wherein one straight edge of the upper body part 523 is in contact with the outer wall surface of the upper groove wall of the sliding groove 51, the other straight edge of the upper body part 523 extends downward, one straight edge of the lower body part 524 is in contact with the outer wall surface of the lower groove wall of the sliding groove 51, the other straight edge of the lower body part 524 extends upward, and a gap serving as the through opening 521 is formed between the upper end of the straight edge extending upward of the lower body part 524 and the lower end of the straight edge extending downward of the upper body part 523.

[0070] Preferably, the front and rear ends of the stop member 52 are respectively provided with clamping members 55, which fasten the upper split portion 523 and the lower split portion 524 to the rail body 53, and the clamping members 55 located at the front and rear ends of the stop member 52 can also close the front and rear ends of the through opening 521, so that the clamping members 55 and the connecting member 47 are limitedly cooperated to prevent the sliding member 46 from sliding out of the sliding groove 51, thereby improving the reliability of the workpiece processing device 100.

[0071] Further preferably, the through-hole 521 is in a closed shape, that is, the size of the through-hole 521 gradually decreases from the outside to the inside, thereby further reducing the waste powder and cooling liquid splashing into the sliding groove 51. In addition, a plurality of through holes 522 are provided on the lower part 524 of the stopper 52, so that the waste powder and cooling liquid entering the sliding groove 51 can be discharged from the through holes 522, thereby avoiding affecting the sliding of the sliding member 46 to improve the reliability of the workpiece processing device 100.

[0072] Those skilled in the art can understand that the structure of the above-mentioned sliding rail 5 can be applied to the sliding rails 5 on different sides of the workpiece processing position 31, and it is only necessary to adaptively change the direction of the slot; in fact, in order to further prevent waste powder and cooling liquid from entering the sliding groove 51, the slot direction of the sliding groove 51 can also be set upward, and it is only necessary to adaptively change the structure of the connecting member 47 to connect the sliding member 46 and the electromagnetic cover plate 44. The above-mentioned embodiments all belong to the protection scope of the present application.

[0073] In the actual processing process, a single clamping component 4 may not be able to meet the demand. For example, when processing the middle part of the workpiece, the single clamping component 4 needs to move to the periphery of the workpiece to continuously clamp the workpiece. At this time, the clamping force may be insufficient, causing the workpiece to shift or warp. Therefore, the workpiece processing device 100 includes multiple clamping components 4, and the workpiece is clamped through the coordinated cooperation of multiple clamping components 4, so as to achieve the abnormal situation that the workpiece does not shift or warp under various working conditions, thereby improving the practicality of the workpiece processing device 100.

[0074] Four clamping assemblies 4 and two sliding rails 5 are used as exemplary embodiments for explanation. In some embodiments, a first placement area is provided between the workpiece processing area and the area to be processed, and a second placement area is provided between the workpiece processing area and the processed area. The two sliding rails 5 are respectively located on the left and right sides of the workpiece processing area and extend from the first placement area to the second placement area along the front-to-back direction. The four clamping assemblies 4 are arranged in a rectangular shape, wherein the two clamping assemblies 4 on the left side slide in cooperation with the sliding rail 5 on the left side, and the two clamping assemblies 4 on the right side slide in cooperation with the sliding rail 5 on the right side. When the workpiece to be processed is placed in the workpiece processing position 31 or the processed workpiece is moved out of the workpiece processing position 31, the two clamping assemblies 4 on the front side slide forward to the first placement area, and the two clamping assemblies 4 on the rear side slide backward to the second placement area.

[0075] Preferably, the clamping assembly 4 also includes a collision detection component electrically connected to the control unit. The collision detection component is arranged on the side where the adjacent clamping assemblies 4 in the front-to-back direction face each other and is used to detect the distance between the adjacent clamping assemblies 4 in the front-to-back direction, thereby avoiding collision between the adjacent clamping assemblies 4 in the front-to-back direction during movement, thereby improving the reliability of the workpiece processing assembly.

[0076] like Figure 7 and Figure 8 As shown, in some embodiments, the workpiece processing device 100 also includes a first workpiece transfer component 6 located between the workpiece processing position 31 and the to-be-processed position 32, and a second workpiece transfer component 7 located between the workpiece processing position 31 and the processed position 33. The workpiece to be processed is transferred to the workpiece processing position 31 by the first workpiece transfer component 6, and the workpiece that has been processed is transferred to the processed position 33 by the second workpiece transfer component 7. In addition, the first workpiece transfer component 6 and the second workpiece transfer component 7 are both electrically connected to the control unit, so that the operation of the first workpiece transfer component 6 and the second workpiece transfer component 7 are controlled by the control unit, thereby improving the degree of automation of the workpiece processing device 100 and reducing the labor intensity of technicians, so as to improve the processing efficiency of the workpiece.

[0077] Generally, the first workpiece transfer assembly 6 and the second workpiece transfer assembly 7 can complete the transfer of the workpiece in space. However, due to technical limitations, the first workpiece transfer assembly 6 and the second workpiece transfer assembly 7 only have the function of transferring the workpiece in the up and down direction but not in the horizontal direction, or have the function of transferring the workpiece in the up and down direction and have the function of transferring the workpiece in a small range in the horizontal direction.

[0078] In response to the above situation, in some embodiments, the workpiece processing device 100 includes a transfer track extending along the workpiece transfer direction, the processing table 3 slides with the transfer track, and the separation of the workpiece and the processing table 3 is achieved by the first workpiece transfer component 6 and the second workpiece transfer component 7. The relative movement of the workpiece in the horizontal direction is achieved by the sliding cooperation between the processing table 3 and the transfer track, thereby realizing the transfer of the workpiece in space.

[0079] Preferably, the first workpiece transfer assembly 6 and the second workpiece transfer assembly 7 both include a telescopic member 71 and a vacuum adsorption member 72 , wherein the telescopic member 71 can be telescopic in the up and down directions, and the vacuum adsorption member 72 is arranged at the telescopic end of the telescopic member 71 and is used to adsorb the workpiece.

[0080] Specifically, the vacuum suction member 72 includes an air pump 721, an air tube 722, a guide pin 723, a small air tube 724 and a suction cup 725. The air tube 722 is formed with a first air cavity 726 and a second air cavity 727 which are interconnected from top to bottom, and the inner diameter of the first air cavity 726 is larger than the inner diameter of the second air cavity 727, that is, a step portion is formed at the connection between the first air cavity 726 and the second air cavity 727, and the guide pin 723 is axially slidably matched with the cavity wall of the first air cavity 726 and is limitedly matched with the step portion. The guide pin 723, the small air tube 724 and the suction cup 725 are sequentially connected along the axial direction, one end of the small air tube 724 is located in the second air cavity 727, and the other end of the small air tube 724 extends out of the second air cavity 727 along the axial direction, and the air pump 721, the first air cavity 726, the guide pin 723, the small air tube 724 and the suction cup 725 are sequentially connected along the axial direction. When the workpiece needs to be sucked, the telescopic member 71 extends downward until the suction cup 725 contacts the workpiece. At the same time, the air pump 721 is started during the extension process to form a negative pressure state, and a closed state is formed after the suction cup 725 contacts the workpiece, so that the suction cup 725 can suck the workpiece tightly.

[0081] Furthermore, the vacuum adsorption component 72 also includes a second spring 728 and a plug 729. The second spring 728 is sleeved on the small air tube 724, and the plug 729 is blocked at the lower end outlet of the small air cavity. The upper end of the second spring 728 contacts the lower end surface of the guide ejector pin 723, and the lower end of the second spring 728 contacts the upper end surface of the plug 729. The initial axial length of the second spring 728 is greater than the axial distance between the upper end surface of the plug 729 and the lower end surface of the guide ejector pin 723. When a negative pressure state is formed or released, the guide ejector pin 723 will vibrate in the axial direction. The elastic force of the second spring 728 applies an axial buffering force to the guide ejector pin 723, thereby avoiding the collision and wear of the guide ejector pin 723 with the step portion, thereby extending the service life of the hollow adsorption component.

[0082] Preferably, the first workpiece transfer assembly 6 and the second workpiece transfer assembly 7 also include a proximity detection member 73, a negative pressure detection member and an elastic force detection member. The proximity detection member 73 is used to detect the distance between the vacuum adsorption member 72 and the workpiece, the negative pressure detection member is used to detect the negative pressure value in the atmospheric pipe 722, and the elastic force detection member is used to detect the elastic force of the second spring 728. The specific process is as follows: the technician needs to predetermine the starting distance, the starting negative pressure value and the closing elastic force value; when the telescopic end of the telescopic member 71 extends downward until the distance between the vacuum adsorption member 72 and the workpiece reaches the starting distance, the air pump 7 is started. 21 begins to form negative pressure; when the telescopic end of the telescopic member 71 continues to extend downward until the suction cup 725 contacts the workpiece to form a closed state, the telescopic member 71 stops extending; when the negative pressure value in the atmospheric cavity reaches the starting negative pressure value, the telescopic end of the telescopic member 71 shortens upward to achieve the upward transfer of the workpiece; when the workpiece is transferred into place in the horizontal direction, the telescopic end of the telescopic member 71 extends downward to achieve the downward transfer of the workpiece; when the workpiece contacts the processing table 3 and the elastic force of the second spring 728 reaches the closing elastic force value, the air pump 721 is turned off to release the negative pressure to separate the suction cup 725 and the workpiece.

[0083] Further preferably, the elastic force detection member, negative pressure detection member, proximity detection member 73, telescopic member 71 and air pump 721 are all electrically connected to the control unit, and the technician inputs the starting distance, starting negative pressure value and closing elastic force value into the control unit in advance, and the control unit completes the transfer of the workpiece according to the above-mentioned specific process.

[0084] Those skilled in the art will appreciate that the elastic force detection member, negative pressure detection member and proximity detection member 73 may be various types of sensors, and the structures and principles of various types of sensors are well known to those skilled in the art, and do not belong to the core improvement points of the present application, so they will not be elaborated here; the telescopic member 71 may be an electric telescopic rod, a hydraulic telescopic rod, etc., and the structures and principles of various types of telescopic rods are well known to those skilled in the art, and do not belong to the core improvement points of the present application, so they will not be elaborated here.

[0085] In some embodiments, the workpiece processing device 100 also includes a movable spindle extending in the up and down directions, and a movable seat 1 is slidably arranged on the movable spindle. The movable seat 1 is located above the processing table 3 and is provided with a processing tool. After the clamping assembly 4 is pressed and matched with the workpiece processing position 31, the movable seat 1 moves downward and processes the workpiece.

[0086] Preferably, a probe is provided on the movable seat 1. The probe is a common tool used in the field of CNC machining, mainly used to detect the position, shape and surface quality of the workpiece. There are various types of probes, such as fixed probes, adjustable probes, magnetic probes, etc. The appropriate probe type is selected according to different machining requirements.

[0087] Specifically, the probe is connected to the control unit for communication. The probe sends the actual position information of the detected workpiece to the control unit. The control unit compares the actual position information with the ideal position information. When the error between the actual position information and the ideal position information is within the allowable range, the moving seat 1 is controlled to perform subsequent processing. When the error between the actual position information and the ideal position information exceeds the allowable range, the first workpiece transfer component 6 or the second workpiece transfer component 7 is controlled to cooperate with the processing table 3 to adjust the workpiece position. In the present application, the probe is set to ensure that the workpiece is placed accurately, thereby ensuring the processing accuracy of the workpiece, thereby ensuring the processing quality of the workpiece and improving the production efficiency of the workpiece.

[0088] Furthermore, the first workpiece transfer assembly 6 and the second workpiece transfer assembly 7 are connected to the moving seat 1 and are respectively arranged on the front and rear sides of the moving seat 1. The moving seat 1 drives the first workpiece transfer assembly 6 and the second workpiece transfer assembly 7 to move in the up and down directions, thereby increasing the height range of the workpieces transferred by the first workpiece transfer assembly 6 and the second workpiece transfer assembly 7, and thus being suitable for workpieces of different sizes to improve the application range of the workpiece processing device 100.

[0089] The exemplary embodiment of the present application provides a workpiece processing device 100, comprising a processing table 3, a transfer track, four clamping assemblies 4, two sliding tracks 5, a moving spindle, a moving seat 1, a first workpiece transfer assembly 6, a second workpiece transfer assembly 7 and a control unit, wherein a to-be-processed position 32, a workpiece processing position 31 and a processed position 33 are arranged on the processing table 3 at intervals along the front-to-back direction, and the specific processing flow is as follows:

[0090] First, the technician places the workpiece to be processed at the processing position 32 and starts the workpiece processing device 100 according to the preset program of the control unit;

[0091] Secondly, the processing table 3 moves along the transfer track until the workpiece on the processing position 32 is aligned with the vacuum suction member 72 of the first workpiece transfer assembly 6 in the vertical direction, and the moving seat 1 moves downward or the telescopic rod extends downward until the suction cup 725 sucks the workpiece tightly;

[0092] Subsequently, the movable seat 1 moves upward or the telescopic rod shortens upward until the workpiece is separated from the processing position 32 and does not interfere with the clamping assembly 4;

[0093] Next, the processing table 3 moves along the transfer track until the workpiece processing position 31 is aligned with the workpiece adsorbed by the vacuum adsorbent 72 in the vertical direction, and the moving seat 1 moves downward or the telescopic rod extends downward until the workpiece is placed in the workpiece processing position 31 and separated from the suction cup 725;

[0094] Subsequently, the probe detects the position of the workpiece in the workpiece processing position 31. When the error between the actual position information of the workpiece and the ideal position information is within the allowable range, the clamping assembly 4 moves from the placement area to above the workpiece processing position 31, and a processing gap is formed between the multiple clamping assemblies 4, and the processing gap corresponds to the area to be processed on the workpiece;

[0095] Secondly, the control unit controls the PLC module 48 to energize the first electromagnet part 411 and the second electromagnet part 412 to form a mutually repelling magnetic force, and the second electromagnet part 412 drives the workpiece clamping member 42 to move downward to clamp the workpiece. At this time, the pressure detection member 2 feeds back the pressure of the workpiece to the control unit in real time so that the control unit can adjust the current passed into the first electromagnet part 411 and the second electromagnet part 412 in real time;

[0096] Then, the moving seat 1 drives the machining tool to move downward and pass through the machining gap to machine the area to be machined of the workpiece;

[0097] When the next area to be processed needs to be processed, the corresponding clamping assembly 3 is moved according to the positional relationship between the current area to be processed and the next area to be processed to expose the next area to be processed of the workpiece, and the remaining clamping assemblies 3 keep clamping the workpiece. Before moving the clamping assembly 3, the clamping force needs to be reduced until it is separated from the workpiece. After moving the clamping assembly 3, the processing table 3 moves along the transfer track to move the next area to be processed to below the processing tool to process the next area to be processed of the workpiece;

[0098] Next, after the processing is completed, the control unit controls the PLC module 48 to cancel the power supply to the first electromagnet part 411 and the second electromagnet part 412, and the clamping assembly 4 moves from the workpiece processing position 31 to the placement area;

[0099] Subsequently, the processing table 3 moves along the transfer track until the workpiece on the workpiece processing position 31 is aligned with the vacuum suction member 72 of the second workpiece transfer assembly 7 in the vertical direction, and the moving seat 1 moves downward or the telescopic rod extends downward until the suction cup 725 sucks the workpiece tightly;

[0100] Secondly, the movable seat 1 moves upward or the telescopic rod shortens upward until the workpiece is separated from the workpiece processing position 31 and does not interfere with the clamping assembly 4;

[0101] Subsequently, the processing table 3 moves along the transfer track until the processed position 33 is aligned with the workpiece adsorbed by the vacuum adsorbent 72 in the vertical direction, and the movable seat 1 moves downward or the telescopic rod extends downward until the workpiece is placed in the processed position 33 and separated from the suction cup 725;

[0102] Finally, technicians transfer the processed workpiece to the next process.

[0103] In the present application, the above-mentioned processing flow is implemented through the workpiece processing device 100, thereby reducing the abnormal situation of deformation, displacement and warping of the workpiece during pressing, thereby reducing the defective rate of the workpiece and improving the processing efficiency of the workpiece, and the entire processing flow is set and executed by the control unit, thereby reducing the labor intensity of technicians and improving the processing efficiency of the workpiece.
