[0058] Furthermore, an installation groove is opened on the upper surface of the jacking base plate 52, and the bearing seat fixing block 55 is arranged in the installation groove. The peripheral side surface of the screw support block 511 has an annular protrusion, and a part of the bearing seat fixing block 55 is abutted against the annular protrusion to press the screw support block 511 into the installation groove.

The two y-direction adjustment guide rail assemblies 51 are used to enable the lifting plate 54 to move accordingly with the position of the workpiece on the workpiece conveying device 200, thereby avoiding displacement of the lifting.
[0061] According to one embodiment of the present invention, the lifting mechanism 5a also includes: a reset photoelectric switch and a photoelectric baffle.

[0062] During operation, the height measuring device 2a and the visual recognition device 3a are driven by the y-direction motion mechanism and the x-direction motion mechanism to move above the workpiece, and the motor 56 works, driving the first screw shaft 510 to rotate through the second synchronous belt 57, and the screw slider 512 moves upward, thereby driving the lifting plate 54 to move upward to lift the workpiece to an appropriate position.
[0063] like Figures 7 to 10As shown, the workpiece conveying device 4a according to an embodiment of the present invention includes: a workpiece conveying device 1c and a workpiece carrier 4c. The workpiece conveying device 1c is used to convey the workpiece to move along the x-direction. The workpiece conveying device 1c includes: two conveying components and multiple detection optical fibers. The two conveying components are symmetrically arranged about the xz plane; multiple detection optical fibers are provided on the first conveying component and the second conveying component to detect the conveying status of the workpiece; the workpiece carrier 4c is provided on the two conveying components, and the workpiece carrier 4c carries the workpiece. The present invention has a simple structure. By arranging multiple detection optical fibers on the workpiece conveying path, on the one hand, the conveying position of the workpiece is detected to facilitate positioning; on the other hand, the state of the workpiece is detected to avoid the waste of processing resources and processing time caused by poor workpiece state, thereby improving production efficiency, reducing processing costs, reducing subsequent detection work, and improving the final yield.
[0064] In some specific embodiments of the present invention, Figure 10 As shown, the conveying assembly includes: a base plate 10 and a belt drive device 13. The belt drive device 13 is arranged on the side of the base plate 10 facing the workpiece carrier 4c. When the belt drive device 13 drives the workpiece carrier 4c to move, the base plate 10 can be guided to avoid deviation of the workpiece carrier 4c during movement.
[0065] According to one embodiment of the present invention, a belt drive device 13 includes: two driven pulleys 13c, a belt support strip 13d, a first synchronous belt 13a, and multiple tensioning pulleys 13b. The two driven pulleys 13c are located at the left and right ends of the base plate 10; the belt support strip 13d is located on the base plate 10 and is located between the two driven pulleys 13c; the first synchronous belt 13a is sleeved on the two driven pulleys 13c and the belt support strip 13d; and multiple tensioning pulleys 13b are located on the base plate 10, with the multiple tensioning pulleys 13b abutting against the outer periphery of the first synchronous belt 13a. Furthermore, one belt drive device 13 includes a driving pulley 13e and a drive motor 13f. The driving pulley 13e meshes with the inner periphery of the first synchronous belt 13a. The output end of the drive motor 13f is connected to the driving pulley 13e. The drive motor 13f is located on the base 11. Furthermore, the workpiece handling device 1c also includes: a coupling 19 and a spline shaft 110. One end of the spline shaft 110 is directly connected to the driven wheel 13c of the first conveying component. One end of the spline shaft 110 can be movably inserted into the center of the driven wheel 13c of the first conveying component along the y direction. When processing workpieces of different sizes, it is necessary to adjust the distance between the two substrates 10. The direct connection of the spline shaft 110 ensures that the two substrates 10 always maintain a direct connection state regardless of whether they are close or far away, and the power transmission process will not be affected. The other end of the spline shaft 110 is connected to one end of the coupling 19, and the other end of the coupling 19 is connected to the driven wheel 13c of another conveying component. When only one drive motor 13f is used to drive the two first synchronous belts 13a at the same time, the movement process can be uniformly controlled, avoiding the occurrence of asynchronous situations when the two drive motors 13f drive the two first synchronous belts 13a to move respectively. The two belt drive devices 13 are connected by the coupling 19 and the spline shaft 110, ensuring that when the two belt drive devices 13 move, the movement processes of the two first synchronous belts 13a remain consistent, thereby improving the stability of the workpiece carrier 4c moving along the x-direction.
[0066] According to one embodiment of the present invention, Figure 8 and Figure 9 As shown, multiple detection optical fibers include: an input detection optical fiber 14, a deceleration detection optical fiber 15, an arrival detection optical fiber 18 and an output detection optical fiber 111.

The movement state of the workpiece carrier 4c can be obtained at all times, which is convenient for controlling the processing equipment to process the workpiece at the appropriate position.
[0067] According to one embodiment of the present invention, the workpiece handling device 1c also includes: a side pushing assembly 17 and a material arrival stopping device 112, the side pushing assembly 17 is arranged on the substrate 10, and is located between the deceleration detection optical fiber 15 and the material arrival detection optical fiber 18; the material arrival stopping device 112 is arranged on the substrate 10, and the line connecting the material arrival stopping device 112 and the material arrival detection optical fiber 18 is parallel to the y-axis.
[0068] Furthermore, the multiple detection optical fibers also include: an input warpage detection optical fiber 16 and an output warpage detection optical fiber 113. The input warpage detection optical fiber 16 and the output warpage detection optical fiber 113 can be movably arranged on the substrate 10 along the z-direction. The input warpage detection optical fiber 16 and the output warpage detection optical fiber 113 are respectively located on both sides of the side thrust assembly 17. The input warpage detection optical fiber 16 detects the state of the workpiece before processing, and promptly discovers the warped workpiece to avoid poor processing of the workpiece in the warped state; the output warpage detection optical fiber 113 detects the workpiece after processing, and at the same time, cooperates with the detection results of the input warpage detection optical fiber 16 to comprehensively judge whether the processing process causes the workpiece to warp, and then adjusts the processing process. The input warpage detection optical fiber 16 and the output warpage detection optical fiber 113 are both fixed on the substrate 10 through a lifting bracket 114. When the size of the workpiece changes, the height of the input warpage detection optical fiber 16 and the output warpage detection optical fiber 113 are adjusted by the lifting bracket 114 according to the thickness of the workpiece, thereby improving the applicability of the detection process.
[0069] According to one embodiment of the present invention, the workpiece handling device 1c also includes: a base 11 and two y-guide rails 12, the two y-guide rails 12 are arranged on the base 11, the two y-guide rails 12 are arranged parallel to the y-axis, and the conveying assembly is slidably arranged on the two y-guide rails 12, each y-guide rail 12 has two sliders, and the two substrates 10 are respectively connected to the two sliders. The relative positions of the two substrates 10 are adjusted by the two sliders, which is convenient for adjusting the relative positions of the two substrates 10 when processing workpieces of different sizes.
[0070] According to one embodiment of the present invention, the workpiece conveying device 4a also includes: a lifting mechanism 5a and a leveling adsorption locking fixture 3c. The lifting mechanism 5a is arranged on the base 11 and is located directly below the movement trajectory of the workpiece carrier 4c. The leveling adsorption locking fixture 3c is fixed on the upper surface of the lifting mechanism 5a.
[0071] like Figures 11 to 14As shown, the levelable adsorption and locking fixture 400 according to an embodiment of the present invention includes: a universal mounting adapter plate 141 and an adsorption and locking fixture 144. The universal mounting adapter plate 141 is a straight plate. Four leveling bolt assemblies 145 are provided around the universal mounting adapter plate 141. The leveling bolt assemblies 145 fix the universal mounting adapter plate 141 on the jacking mechanism 5a. By screwing the four leveling bolt assemblies 145, the upper surface of the universal mounting adapter plate 141 is adjusted to be parallel; the adsorption and locking fixture 144 is provided on the upper surface of the universal mounting adapter plate 141, and the adsorption and locking fixture 144 carries a workpiece.
[0072] The beneficial effect of the present invention is that the present invention has a simple structure, and the heights of the four corners of the universal mounting adapter plate 141 are adjusted by four leveling bolt assemblies 145, thereby indirectly adjusting the workpiece on the adsorption locking fixture 144 to be parallel. The leveling process is convenient, and direct interference between the leveling and the workpiece is avoided.
[0073] According to one embodiment of the present invention, the universal mounting adapter plate 141 is provided with four fine-threaded holes 141a along the thickness direction. One end of the leveling bolt assembly 145 is disposed within the fine-threaded hole 141a, and the other end of the leveling bolt assembly 145 is connected to the jacking mechanism 5a. The universal mounting adapter plate 141 is provided with four slits 141b along the thickness direction, and the slits 141b are connected to the fine-threaded holes 141a. Four horizontal locking screws 146 are provided around the universal mounting adapter plate 141. The horizontal locking screws 146 pass through the slits 141b. The horizontal locking screws 146 are rotated to adjust the size of the slits 141b, thereby adjusting the size of the fine-threaded hole 141a, ultimately achieving a tight connection between the fine-threaded hole 141a and the leveling bolt assembly 145. Furthermore, the axis of the horizontal locking screw 146 is perpendicular to the axis of the leveling bolt assembly 145. The horizontal locking screw 146 is used to lock from the side, thereby avoiding the generation of z-direction force during locking, thereby reducing the interference of the locking process on the leveling process.
[0074] According to one embodiment of the present invention, Figure 14As shown, the leveling bolt assembly 145 includes: a leveling piece 145a, a spherical gasket 145b and a connecting piece 145c. The leveling piece 145a is a cylindrical piece. A fine external thread 145a1 is provided on the outer periphery of the leveling piece 145a. The fine external thread 145a1 cooperates with the fine threaded hole 141a. A leveling hole is provided on the leveling piece 145a that passes through the thickness direction; the spherical gasket 145b is provided between the leveling piece 145 and the lifting mechanism; one end of the connecting piece 145c passes through the leveling hole and the spherical gasket 145b and is connected to the lifting mechanism 5a. Furthermore, the upper portion of the leveling hole is formed with a hexagonal countersunk head 145a2, facilitating leveling operations after inserting a wrench. The middle portion of the leveling hole is formed with a cylindrical countersunk hole 145a3, into which the other end of the connector 145c is secured. The cooperation between the cylindrical countersunk hole 145a3 and the connector 145c prevents interference between the threaded connection of the fine external thread 145a1 and the varying leveling angle. Furthermore, the spherical contact between the upper and lower washers of the spherical washer 145b ensures that the leveling effect is not affected by angle changes during the leveling process. Preferably, the connector 145c is a hexagon socket head cap screw.
[0075] According to one embodiment of the present invention, Figure 11 As shown, the leveling adsorption locking fixture 400 also includes: a heating plate 142 and a heat insulation plate 143, the heating plate 142 is arranged between the universal mounting adapter plate 141 and the jacking mechanism 5a; the heat insulation plate 143 is arranged between the heating plate 142 and the jacking mechanism 15a, and the heating plate 142 and the heat insulation plate 143 are both provided with through holes that are clearance-matched with the leveling bolt assembly 145.
[0076] According to one embodiment of the present invention, Figure 13 As shown, the adsorption and locking fixture 144 includes: a main body 144a, multiple suction cups 144b and a vacuum connector 144c. The multiple suction cups 144b are spaced apart on the upper surface of the main body 144a, and the workpiece is adsorbed on the suction cups 144b; the vacuum connector 144c is provided on the side of the main body 144a, and the vacuum connector 144c is connected to the multiple suction cups 144b.
[0077] Furthermore, the adsorption locking fixture 144 also includes: a fill light plate 144d, which is arranged on the upper surface of the main body 144a. The upper surface of the fill light plate 144d is a mirror surface, which is convenient for the visual recognition device to identify the contour of the workpiece by using mirror reflection, so that the light source for contour recognition is enhanced, thereby improving the accuracy of workpiece contour recognition.
[0078] During use, screw the leveling piece 145a into the fine threaded hole 141a, then place the connecting piece 145c into the leveling hole, rotate the connecting piece 145c so that the lower end of the connecting piece 145c is fixed to the jacking mechanism, and then rotate the leveling piece 145a for leveling. After leveling is completed, tighten the horizontal locking screw 146 to complete the locking of the leveling bolt assembly 145.
[0079] like Figures 15 to 17 As shown, the automatic weighing and glue-breaking device 6a according to an embodiment of the present invention includes: a weighing windproof device 2b, a first accommodating chamber is defined in the weighing windproof device 2b; a weighing device 1b, the weighing device 1b is arranged in the first accommodating chamber; a fluid segmentation device 4b, the fluid segmentation device 4b is arranged above the weighing windproof device 2b, the fluid segmentation device 4b has a second accommodating chamber, and the second accommodating chamber is communicated with the first accommodating chamber; a fluid receiving container 3b, the fluid receiving container 3b is arranged in the second accommodating chamber, the fluid receiving container 3b is located above the weighing device 1b, and the fluid receiving container 3b has two states: glue-breaking and weighing. When the fluid receiving container 3b is in the glue-breaking state, the fluid receiving container 3b moves upward to receive glue. When the fluid receiving container 3b is in the weighing state, the fluid receiving container 3b moves downward and is placed on the weighing device 1b to weigh the glue. The present invention has a simple structure. By placing the weighing device 1b and the fluid receiving container 3b in the accommodating cavity, it ensures that the weighing process is not disturbed. The glue is segmented by the fluid segmenting device 4b to ensure that the glue dispensing amount measured each time is more accurate.
[0080] According to one embodiment of the present invention, Figure 15 As shown, the weighing windproof device 2b includes: a base plate 21 and a windproof cover 22, the weighing device 1b is arranged on the upper surface of the base plate 21; the windproof cover 22 is covered above the weighing device 1b, and the windproof cover 22 is sealed to the edge of the base plate 21, the upper end of the windproof cover 22 has an opening, and the fluid segmentation device 4b is arranged on the opening.
[0081] According to one embodiment of the present invention, Figure 16 and Figure 17As shown, the fluid segmentation device 4b includes: a sealing base 411, a sealing cover 47, a weighing pan 412, a clamping ring 48 and a z-direction motion cylinder 41. The sealing base 411 is arranged at the opening, and the middle part of the sealing base 411 has a through hole; the sealing cover 47 is located on the sealing base 411, and the lower end of the sealing cover 47 is arranged in the through hole, the sealing cover 47 has an upper opening and a lower opening, and the inner periphery of the lower opening protrudes inward to form a boss 47a; the weighing pan 412 is arranged in the sealing cover 47, and when the fluid receiving container 3b is in the glue-breaking state, the weighing pan 412 is clamped on the boss 47a; the clamping ring 48 is sleeved on the sealing cover 47; one end of the z-direction motion cylinder 41 is arranged on the sealing base 411, and the other end of the z-direction motion cylinder 41 is connected to the clamping ring 48 through the cylinder connecting block 42 to drive the sealing cover 47 to move up and down.
[0082] According to one embodiment of the present invention, Figure 17 As shown, the fluid receiving container 3b is disposed on the scale pan 412. The fluid receiving container 3b comprises an outer conical surface 32 and an inner conical surface 31. The diameter of the outer conical surface 32 decreases from top to bottom, while the diameter of the inner conical surface 31 increases from top to bottom. The inner conical surface 31 is disposed within the outer conical surface 32, with the lower edge of the inner conical surface 31 connected to the lower edge of the outer conical surface 32, forming a glue-receiving chamber between the inner conical surface 31 and the outer conical surface 32. Furthermore, the upper edge of the inner conical surface 31 is higher than the upper edge of the outer conical surface 32, and both the inner conical surface 31 and the outer conical surface 32 are frustum-shaped surfaces. Compared to a straight cylindrical surface, a frustum-shaped surface is more likely to come into contact with the glue, making it more likely for the glue to fall along the inner conical surface 31 or the outer conical surface 32 when the glue breaks. Furthermore, the upper portion of the glue-receiving chamber formed between the inner conical surface 31 and the outer conical surface 32 has a larger space, preventing the glue tip from colliding with the inner conical surface 31 or the outer conical surface 32.
[0083] According to one embodiment of the present invention, Figure 16 and Figure 17 As shown, the fluid segmentation device 4b also includes: a weighing cover 45, which is arranged at the upper opening. A glue cutting port 45a is provided on the weighing cover 45, and the positive projection of the center point of the glue cutting port 45a falls on the inner conical surface 31. An elastic ring 44 is also provided on the glue cutting port 45a. The elastic ring 44 cushions the glue head to avoid hard contact between the glue head and the glue cutting port 45a. This design ensures that when the glue head enters the glue cutting port 45a for glue cutting, the center of the glue head is above the inner conical surface 31, and the glue falls on the inner conical surface 31 and slides along the inner conical surface 31.
[0084] According to one embodiment of the present invention, the peripheral side surface of the weighing cover 45 is connected to the inner peripheral surface of the upper opening. Two annular grooves 45b and a positive pressure groove 45d are opened on the peripheral side surface of the weighing cover 45. The positive pressure groove 45d is located between the two annular grooves 45b.
[0085] According to a preferred embodiment of the present invention, Figure 17As shown, the weighing cover 45 is provided with an air expansion hole 45f and a plurality of air guide holes 45e. The air expansion hole 45f is located directly below the glue breaking port 45a, and the air expansion hole 45f is connected to the glue breaking port 45a. The air expansion hole 45f is a bell mouth opening downward; the plurality of air guide holes 45e are arranged in a circular array with the center point of the glue breaking port 45a as the center of the circle, one end of the air guide hole 45e is connected to the air expansion hole 45f, and the other end of the air guide hole 45e is connected to the positive pressure groove 45d, and the gas is introduced through the positive pressure groove 45d, and the gas is introduced into the air expansion hole 45f by using the air guide hole 45e. The bell mouth can concentrate the gas and spray it downward, ensuring that the glue is peeled off from the glue head when the gas moves downward.
[0086] According to one embodiment of the present invention, Figure 16 As shown, the fluid segmentation device 4b also includes: a positive pressure blowing joint 46 and a vacuum negative pressure joint 49, the positive pressure blowing joint 46 is connected to the positive pressure groove 45d; the vacuum negative pressure joint 49 is arranged at the lower part of the outer cone 32 and is connected to the glue holding chamber, and uses positive pressure gas to blow air from the glue head and negative pressure gas to suck air from the glue holding chamber, thereby ensuring that the glue moves along the top-down flow direction of the gas, making it easier for the glue to be peeled off from the glue head.
[0087] According to one embodiment of the present invention, Figure 17 As shown, the fluid segmentation device 4b also includes: two first sealing rings 43 and a second sealing ring 410, and each annular groove 45b is provided with a first sealing ring 43; the second sealing ring 410 is arranged between the sealing cover 47 and the sealing base 411. By arranging the first sealing ring 43 and the second sealing ring 410, it is ensured that during the two processes of cutting the glue and weighing, the sealing cover 47 and the windproof cover 22 are always in a windless state, avoiding external interference and ensuring accurate measurement results.
[0088] During operation, the workpiece is placed on the workpiece carrier 4c, and the two ends of the workpiece carrier 4c move along the x-axis driven by the first synchronous belt 13a. The feed detection optical fiber 14 detects whether the workpiece carrier 4c enters the conveying assembly. When the deceleration detection optical fiber 15 detects the workpiece carrier 4c, the drive motor 13f starts to decelerate. At the same time, the feed warping detection optical fiber 16 detects the upper surface of the passing workpiece, and an alarm is issued if the workpiece is warped. When the workpiece carrier 4c moves to the material arrival detection optical fiber 18, the material arrival blocking device 112 rises upward to complete the blocking of the workpiece carrier 4c, and then the side pushing assembly 17 pushes the workpiece carrier 4c to counteract the substrate 10 to ensure that the workpiece carrier 4c is positioned in the x-direction and y-direction. Then the lifting mechanism 5a lifts the workpiece carrier 4c upward, and the leveling adsorption locking fixture 400 adsorbs and fixes the workpiece; the height measuring device 2a and the visual The visual recognition device 3a moves to the top of the workpiece under the drive of the y-direction motion mechanism and the x-direction motion mechanism. After the height measuring device 2a measures the height of the workpiece carrier 4c, the lifting mechanism 5a performs height compensation to complete the z-direction positioning, and then the visual recognition device 3a performs photo detection; the y-direction motion mechanism, the x-direction motion mechanism and the z-direction motion mechanism work together to move a fluid dispenser to the top of a chip for dispensing processing, the x-direction motion mechanism and the other z-direction motion mechanism work together to move the other fluid dispenser to another chip, and then use the y-direction fine-tuning device 1a1 to perform fine-tuning in the y direction, so that the other fluid dispenser moves to the top of another chip for dispensing processing; after the processing is completed, when discharging, the discharging warping detection optical fiber 113 performs a secondary inspection on the workpiece, and the discharging detection optical fiber 111 detects the discharging position of the workpiece carrier 4c.
[0089] Every time the equipment is started or the fluid dispenser is replaced, the glue dispensing amount is weighed and calibrated, and the z-axis motion cylinder 41 drives the sealing cover 47 to move upward, so that the boss 47a lifts the scale plate 412 and the fluid receiving container 3b upward, and then the glue head of the fluid dispenser extends into the glue breaking port 45a and enters the air expansion hole 45f. The positive pressure blowing connector 46 and the vacuum negative pressure connector 49 work, and through blowing and sucking, the glue on the glue head is smoothly introduced into the fluid receiving container 3b. Then the positive pressure blowing connector 46 and the vacuum negative pressure connector 49 stop working, and the z-axis motion cylinder 41 moves downward, so that the scale plate 412 and the fluid receiving container 3b fall on the weighing device 1b for weighing.
