[0083] When the xyz fine-tuning device 4 for the dual-fluid distribution operation is working, the z-direction motion device 33 moves downward to the processing height of the second fluid distributor, and then the z-direction adjustment device 43c drives the first fluid distributor to perform z-direction fine-tuning, so that the first fluid distributor is aligned with the first workpiece, and then the y-direction adjustment device 41c drives the second fluid distributor to fine-tune a certain distance along the y-axis, and the x-direction adjustment device 42b drives the second fluid distributor to fine-tune a certain distance along the x-axis, so that the second fluid distributor is aligned with the second workpiece, thereby achieving the goal of simultaneous processing of the two products when the relative positions of the two products change.

The present invention utilizes the first x-direction workpiece flow device 23 to transport the workpiece, and by providing the workpiece positioning and clamping device 25 to position and clamp the workpiece in the front and rear directions and the upper and lower directions of the workpiece transport path, it ensures that the workpiece remains stable during processing, thereby improving the yield rate.

[0085] Furthermore, if Figure 14 As shown, the workpiece handling, positioning, and clamping device 2 further includes: a base plate 21; a second x-direction workpiece flow device 24, which is arranged parallel to the first x-direction workpiece flow device 23; and a y-direction position adjustment mechanism 22, which is disposed on the base plate 21. The axis of the y-direction position adjustment mechanism 22 is parallel to the y-axis. The first x-direction workpiece flow device 23 and the second x-direction workpiece flow device 24 are disposed on the y-direction position adjustment mechanism 22 and are movable along the axis of the y-direction position adjustment mechanism 22.

[0088] like Figures 21 to 24 As shown, the side-pushing clamping device 25c includes: a side-pushing workpiece guide bar 25c1, a side-pushing guide mounting seat 25c3, and a side-pushing assembly 25c2.

A portion of the side-pushing assembly 25c2 is located between the side-pushing workpiece guide bar 25c1 and the workpiece, and a portion of the side-pushing assembly 25c2 can move a certain distance toward the side of the workpiece before abutting against the side of the workpiece. The side-pushing workpiece guide bar 25c1 is first used to guide the workpiece being transported, and then the side-pushing assembly 25c2 moves toward the side of the workpiece to complete the clamping of the workpiece. This first-guiding, then-clamping process ensures that the workpiece can be accurately clamped.

[0089] In some specific embodiments of the present invention, the side-pushing guide mount 25c3 includes a guide mount body 25c31 and at least two side-pushing guide rail assemblies 25c32. The side-pushing guide rail assemblies 25c32 are mounted on the guide mount body 25c31. The axis of the side-pushing guide rail assemblies 25c32 is parallel to the y-axis. The side-pushing assembly 25c2 is mounted on the side-pushing guide rail assemblies 25c32 and is movable along the axis of the side-pushing guide rail assemblies 25c32. The at least two side-pushing guide rail assemblies 25c32 improve the movement accuracy of the side-pushing assembly 25c2 and prevent offset during movement.

[0090] According to one embodiment of the present invention, the side-pushing assembly 25c2 includes a side-pushing movable seat 25c21, a push claw 25c23, and a first limiting screw 25c27. The side-pushing movable seat 25c21 is disposed on the side-pushing guide rail assembly 25c32, and a notch 25c22 is defined in the side-pushing movable seat 25c21. The push claw 25c23 is disposed within the notch 25c22, and a push claw limiting hole 25c231 is defined in the push claw 25c23, extending through the thickness of the workpiece. One end of the first limiting screw 25c27 is connected to the side-pushing movable seat 25c21, and the other end of the first limiting screw 25c27 is inserted into the push claw limiting hole 25c231. The use of the push claw 25c23 can effectively side-pushing and clamping a single workpiece.

[0091] Furthermore, the width of the pawl limiting hole 25c231 along the y-axis is greater than the diameter of the other end of the first limiting screw 25c27, and the slot 25c22 is oriented parallel to the y-axis. Furthermore, the pawl 25c23 is movable within the slot 25c22 in a direction parallel to the y-axis, and the distance of movement is equal to the difference between the width of the pawl limiting hole 25c231 along the y-axis and the diameter of the other end of the first limiting screw 25c27. As the pawl 25c23 moves, it is guided along the slot 25c22.

[0092] According to one embodiment of the present invention, the side push assembly 25c2 also includes: a push plate 25c28, a buffer spring 25c26 and a preload adjustment screw 25c24, the push plate 25c28 is arranged in the slot 25c22, and is located between the end face of the push claw 25c23 and the side wall of the slot 25c22; the buffer spring 25c26 is arranged in the slot 25c22, and is located between the push claw 25c23 and the push plate 25c28, and the axis of the buffer spring 25c26 is parallel to the y-axis; the preload adjustment screw 25c24 is arranged on the side push movable seat 25c21, and one end of the preload adjustment screw 25c24 passes through the side push movable seat 25c21 along the y-axis and then abuts against the push plate 25c28. By tightening or loosening the preload adjustment screw 25c24, the position of the push plates 25c28 in the slot 25c22 is controlled, thereby adjusting the compression degree of the buffer spring 25c26, and finally adjusting the clamping force of the push claw 25c23.

[0093] According to one embodiment of the present invention, a notch 25c33 is further defined on the guide mounting seat body 25c31. The notch 25c33 is located between two adjacent side-pushing guide rail assemblies 25c32, with the opening of the notch 25c33 facing the -y axis. A second limiting screw 25c29 is provided at the lower end of the side-pushing movable seat 25c21, a portion of which is located within the notch 25c33. The distance that the side-pushing assembly 25c2 slides along the y axis is less than or equal to the distance from the second limiting screw 25c29 to the notch 25c33. The interaction between the second limiting screw 25c29 and the notch 25c33 limits the movement distance of the side-pushing movable seat 25c21, thereby preventing excessive extrusion of the chip when the side-pushing movable seat 25c21 moves uncontrollably.

[0094] Preferably, a push claw receiving groove 25c11 is defined on the side of the side-pushing workpiece guide strip 25c1 opposite the workpiece, and the end of the push claw 25c23 closest to the workpiece extends into the push claw receiving groove 25c11. The push claw receiving groove 25c11 conceals the push claw 25c23, ensuring that the workpiece is not obstructed by the push claw 25c23 as it moves along the side of the side-pushing workpiece guide strip 25c1.

[0095] According to one embodiment of the present invention, the side thrust assembly 25c2 further comprises a sealing plate 25c25, which is disposed above the slot 25c22. The sealing plate 25c25 provides good protection for the components within the slot 25c22.

[0096] According to one embodiment of the present invention, the guide mounting base body 25c31 is provided with a plurality of waist-shaped through holes 25c34 extending along the y-axis. The waist-shaped through holes 25c34 facilitate the fixing of the side-pushing guide mounting base 25c3 and allow the fixed height of the side-pushing guide mounting base 25c3 to be adjusted within the waist-shaped space.

[0097] When the side-push clamping device 25c is working, the workpiece moves along the side of the side-push workpiece guide bar 25c1, and the side-push movable seat 25c21 is pushed to move in the y direction by the power component. After the push claw 25c23 contacts the workpiece, it pushes the workpiece in the y direction for a certain distance until the other side of the workpiece is against the Y-direction positioning bar 25a. At this time, the buffer spring 25c26 begins to compress, forming a clamping force on the workpiece.

[0098] like Figures 19 to 20As shown, the workpiece clamping mechanism 25d includes a pressure plate 25d1, one end of which is connected to the Y-axis positioning bar 25a and the other end of which is connected to the side-pushing workpiece guide bar 25c1. A workpiece hole 25d11 is defined in the center of the pressure plate 25d1, extending through the thickness of the workpiece. A plurality of first clamping assemblies 25d2 are positioned below and outside the workpiece hole 25d11 to clamp the edges of the workpiece. A second clamping assembly 25d3 is positioned below the pressure plate 25d1, with at least a portion of the second clamping assembly 25d3 projected along the z-axis into the workpiece hole 25d11 to clamp the center of the workpiece. By defining the workpiece hole 25d11 in the center of the pressure plate 25d1, the first clamping assemblies 25d2 simultaneously clamp the edges of the workpiece and the second clamping assemblies 25d3 simultaneously clamp the center of the workpiece, thereby improving the workpiece clamping effect.

[0099] Furthermore, the workpiece hole 25d11 is a U-shaped structure, and there are four first clamping assemblies 25d2. The four first clamping assemblies 25d2 are respectively arranged on the outside of the four corners of the workpiece hole 25d11. The four corners are clamped at the same time, so that the workpiece is evenly compressed.

[0100] According to one embodiment of the present invention, the pressure plate 25d1 is provided with mounting holes corresponding to the upper and lower parts of the first clamping assembly 25d2. The first clamping assembly 25d2 includes: a connecting block 25d21, a spring 25d22 and a screw. A part of the connecting block 25d21 is inserted into the mounting hole; the spring 25d22 is suspended below the connecting block 25d21; the screw passes through the center of the spring 25d22 to fix the other part of the connecting block 25d21 below the pressure plate 25d1. The spring 25d22 is used to press the workpiece, thereby avoiding hard contact and effectively preventing the workpiece from being crushed.

[0101] Preferably, there are two springs 25d22, the straight line where the two springs 25d22 are located is parallel to the x-axis, and the two springs 25d22 are parallel to the x-axis. The edge of the workpiece is pressed as much as possible to expose the upper surface of the workpiece as much as possible to facilitate subsequent processing.

[0102] According to one embodiment of the present invention, the second clamping assembly 25d3 includes: a steel wire 25d37, the axis of the steel wire 25d37 is parallel to the x-axis, and the projection of the steel wire 25d37 along the z-axis falls on the center line of the workpiece hole 25d11. The steel wire 25d37 is used to clamp the middle of the workpiece, exposing the upper surface of the workpiece as much as possible, reserving sufficient processing space.

[0103] In some embodiments of the present invention, a guide hole 25d12 is formed on the pressure plate 25d1, and the second pressing assembly 25d3 further includes: a fixed wire end, a movable wire end, and a wire intermediate positioning block 25d33. The fixed wire end is located on one side of the workpiece hole 25d11 and is fixedly disposed below the pressure plate 25d1; the movable wire end is located on the other side of the workpiece hole 25d11, and a portion of the movable wire end is movable within the guide hole 25d12; the intermediate positioning block 25d33 is located between the fixed wire end and the movable wire end and is fixedly disposed below the pressure plate 25d1. Furthermore, the fixed wire end includes: a fixed wire positioning block 25d31 and a fixed wire pressing block 25d32 fixed to one side of the fixed wire positioning block 25d31. One end of the wire 25d37 is fixedly disposed between the fixed wire positioning block 25d31 and the fixed wire pressing block 25d32. Furthermore, the movable end of the steel wire includes: a steel wire movable end positioning block 25d34 and a steel wire movable end clamping block 25d35 fixed on one side of the steel wire movable end positioning block 25d34. The other end of the iron wire 25d37 is fixed between the steel wire movable end positioning block 25d34 and the steel wire movable end clamping block 25d35, which positions and fixes the two ends and the middle part of the steel wire 25d37, thereby preventing the steel wire 25d37 from shaking during the clamping process.

[0104] According to one embodiment of the present invention, the second clamping assembly 25d3 also includes: a steel wire tensioning block 25d36, which is fixedly arranged below the pressure plate 25d1; a tensioning screw 25d37, the head of the tensioning screw 25d37 is rotatably connected to the steel wire tensioning block 25d36, and the tip of the tensioning screw 25d37 is screwed into the movable end of the steel wire to drive the movable end of the steel wire to move in the guide hole 25d12, thereby completing the tightness adjustment of the steel wire 25d37. By adjusting the tightness of the steel wire 25d37, the size of the pressing force of the steel wire 25d37 on the product can be adjusted, and the adjustment process is very convenient and controllable.

[0105] Preferably, the steel wire middle positioning block 25d33 is located between the workpiece hole 25d11 and the movable end of the steel wire, and the middle part of the steel wire 25d37 can move along the x-axis between the steel wire middle positioning block 25d33 and the pressure plate 25d1. The steel wire middle positioning block 25d33 only plays a positioning role for the middle part of the steel wire 25d37, ensuring that a part of the steel wire 25d37 is always in the middle of the workpiece hole 25d11.

[0106] When the workpiece clamping mechanism 25d is working, the workpiece clamping mechanism 25d is located directly above the workpiece, the workpiece hole 25d11 corresponds to the workpiece up and down, and the workpiece moves upward until the steel wire 25d37 contacts the middle of the workpiece. Then, the workpiece continues to move upward a short distance of 0.5-1mm, so that the lower end of the spring 25d22 contacts the edge of the workpiece and is compressed. At this time, the workpiece is clamped.

[0107] like Figure 17 As shown, the adsorption tool 25g includes a tool body 25g0. The tool body 25g0 is a straight plate. The upper surface of the tool body 25g0 has a multifunctional area and an adsorption area. The adsorption area is provided with multiple adsorption holes 25g5 and multiple pressure relief grooves 25g8. The multiple adsorption holes 25g5 are arranged in an array along the x-axis and y-axis, and the pressure relief grooves 25g8 are arranged at equal intervals along the x-axis and / or y-axis. One or more rows of adsorption holes 25g5 are provided between adjacent pressure relief grooves 25g8. By providing multiple adsorption holes 25g5 and multiple pressure relief grooves 25g8 in the adsorption area, negative pressure is used to secure the chip, avoiding damage to the chip caused by other fixing methods. The pressure relief grooves 25g8 can partially dissipate the adsorption force, preventing the chip from being affected by excessive adsorption force. When removing the chip, the pressure relief grooves 25g8 can also effectively prevent residual negative pressure from making it difficult to remove the chip.

[0108] Furthermore, the pressure relief grooves 25g8 are evenly spaced on the x-axis, and a row of adsorption holes 25g5 is provided between two adjacent pressure relief grooves 25g8. This design can ensure more uniform adsorption and pressure relief.

[0109] According to one embodiment of the present invention, a negative pressure collecting port 25g9 is provided on the side or lower surface of the tooling body 25g0. This port 25g9 communicates with multiple adsorption holes 25g5. By controlling the negative pressure through a single negative pressure collecting port 25g9, each adsorption hole 25g5 generates the same adsorption force, ensuring uniform force on the chip.

[0110] Furthermore, the multifunctional area is provided with four screw mounting holes 25g2, which are arranged in a rectangular array at the four corners of the tool body 25g0. Furthermore, the multifunctional area is provided with four jackscrew holes 25g3, which are arranged in a rectangular array at the four corners of the tool body 25g0.

[0111] According to one embodiment of the present invention, the multifunctional area includes a first assembly area and a second assembly area, with the adsorption area located between the first and second assembly areas. The first assembly area is provided with two screw mounting holes 25g2 and two jackscrew holes 25g3; the second assembly area is provided with two screw mounting holes 25g2 and two jackscrew holes 25g3.

[0116] When the adsorption tooling 25g is working, it is aligned and installed on the tooling clamping device 25e according to the scale line 25g6, and then the screw is screwed into the screw mounting hole 25g2. Then the height of the top screw in the top screw hole 25g3 is adjusted to make the upper surface of the tooling body 25g0 horizontal, and then the screw is tightened to complete the fixation. The negative pressure collection port 25g9 is connected to the device that generates negative pressure, and the product can be adsorbed through the adsorption hole 25g5.

The upper and lower clamping mechanism 25b can drive the tooling clamping device 25e and the adsorption tooling 25g to move along the z-axis, thereby moving the workpiece toward the workpiece clamping mechanism 25d and clamping the workpiece in the z-axis direction. The upper and lower clamping mechanism 25b includes a cylinder 25b1, a stroke adjustment rod 25b2, a tooling support plate 25b3, and two linear guides 25b4. The tooling support plate 25b3 is located below the tooling adapter plate 25e2. The two linear guides 25b4 are located at the left and right ends of the tooling support plate 25b3.

The handling hook 26a moves along the x-axis and z-axis driven by the hook sliding assembly 26c and the hook lifting assembly 26d to move the workpiece away from the adsorption tooling 25g.

[0121] When the workpiece handling, positioning and clamping device 2 is working, the product moves to the adsorption tooling 25g in the first x-direction workpiece circulation device 23. At this time, the workpiece and the workpiece positioning device 25f are against each other, completing the blocking and limiting of the workpiece in the x-direction, and then the upper and lower clamping mechanisms 25b drive the adsorption tooling 25g to move in the z-axis direction; during the upward movement of the workpiece, the adsorption tooling 25g turns on the negative pressure to adsorb the workpiece; the workpiece continues to move upward, and the side push clamping device 25c starts to work, elastically pressing the side of the workpiece to complete the positioning and pressing of the workpiece in the y-direction; the workpiece continues to move upward until it contacts the workpiece clamping mechanism 25d, and the workpiece clamping mechanism 25d elastically presses the workpiece to complete the pressing of the workpiece in the z-direction.
