[0077] The present invention utilizes a workpiece conveying device 200 to convey the workpiece, measures the workpiece through the measuring part, and simultaneously utilizes the compensation part to drive the leveling adsorption and locking fixture 400 to lift the workpiece upward. When the leveling adsorption and locking fixture 400 lifts the workpiece, it can adsorb and lock the workpiece, thereby completing the fixation before dispensing. The conveying, detection and compensation processes of the workpiece cooperate with each other and can operate independently of each other, meeting the requirements of stable workpiece conveying and automatic detection and compensation before processing.

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 installation groove can be positioned during installation, and at the same time, the installation height of the bearing seat fixing block 55 is further reduced, thereby improving the compactness of the jacking mechanism 5a.

[0085] Furthermore, one end of the first screw shaft 510 extends to the bottom of the lifting base plate 52 , and the synchronous belt 57 is located below the lifting base plate 52 .

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.

[0088] 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 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.

[0089] like Figures 8 to 11 As shown, according to an embodiment of the present invention, the workpiece conveying device 4a includes: a workpiece conveying device 1c and a workpiece carrier 4c. The workpiece conveying device 1c is used to convey the workpiece 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 providing 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 status, thereby improving production efficiency, reducing processing costs, reducing subsequent detection work, and improving the final yield rate.

[0090] In some specific embodiments of the present invention, Figure 11As 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.

[0091] According to one embodiment of the present invention, a belt drive device 13 includes: two first driven pulleys 13c, a belt support strip 13d, a synchronous belt 13a, and multiple tensioning pulleys 13b. The two first 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 first driven pulleys 13c; the synchronous belt 13a is sleeved on the two first 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 synchronous belt 13a. Furthermore, one belt drive device 13 includes a first driving pulley 13d and a first drive motor 13f. The first driving pulley 13d meshes with the inner periphery of the synchronous belt 13a. The output end of the first drive motor 13f is connected to the first driving pulley 13d. The first drive motor 13f is located on the base 11. Furthermore, the workpiece handling device 1c also includes: a first coupling 19 and a spline shaft 110. One end of the spline shaft 110 is directly connected to the first driven wheel 13c of the first conveying component. One end of the spline shaft 110 can be movably inserted into the center of the first 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 first coupling 19, and the other end of the first coupling 19 is connected to the first driven wheel 13c of another conveying component. When only one first drive motor 13f is used to drive two synchronous belts 13a at the same time, the movement process can be uniformly controlled, avoiding the occurrence of asynchronous situations when the two first drive motors 13f drive the two synchronous belts 13a to move respectively. The two belt drive devices 13 are connected by the first coupling 19 and the spline shaft 110, ensuring that when the two belt drive devices 13 move, the movement processes of the two synchronous belts 13a remain consistent, thereby improving the stability of the workpiece carrier 4c moving along the x-direction.

[0093] 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.

[0094] 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.

[0095] 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.

[0097] like Figures 12 to 15 As shown, the leveling adsorption and locking fixture 400 according to the 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.

[0098] 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, and the leveling process is convenient, while avoiding direct interference between the leveling and the workpiece.

[0099] 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.

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.

[0100] According to one embodiment of the present invention, Figure 15As shown, the leveling bolt assembly 145 includes: a leveling piece 145a, a spherical gasket 145b and a connecting piece 145c.

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.

[0103] 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.

[0104] 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.

[0105] like Figures 16 to 18 As shown, the automatic weighing and glue-breaking device 6a according to the embodiment of the present utility model 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 utility model 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.

[0106] According to one embodiment of the present invention, Figure 16 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.

[0107] According to one embodiment of the present invention, Figure 17 and Figure 18As 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.

[0108] According to one embodiment of the present invention, Figure 18 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.

[0109] According to one embodiment of the present invention, Figure 17 and Figure 18 As shown, the fluid segmentation device 4b also includes: a weighing cover 45, which is arranged at the upper opening.

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.

[0110] 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 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.

[0112] According to one embodiment of the present invention, Figure 17 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.

[0113] According to one embodiment of the present invention, Figure 18 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.

[0114] 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 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 first 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 any 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.

[0115] 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.

[0145] Figure 28 1 is a top view of a heat dissipation cover mounting device provided in one embodiment of the present invention when the heat dissipation cover is being attracted. Figure 29 This is a top view of the heat dissipation cover mounting device provided in one embodiment of the present invention when the heat dissipation cover is assembled, combined with Figure 28 and Figure 29 In the present invention, the carrier board is transported to the assembly station through the conveying track module b1; the heat dissipation cover carrier (carrying the heat dissipation cover) is loaded onto the heat dissipation cover loading device b3, and the heat dissipation cover loading device b3 loads the heat dissipation cover carrier to the suction station; the placement module b2 moves to the suction station to suck the heat dissipation cover, such as Figure 3 As shown, the placement module b2 then moves the absorbed heat dissipation cover to the positioning station, and the positioning module b4 positions and identifies the heat dissipation cover absorbed by the placement module b2; then the placement module b2 moves the absorbed heat dissipation cover to the assembly station, and assembles the heat dissipation cover onto the chip in the carrier board at the assembly station, as shown.

Since the heat dissipation cover can be positioned before assembly, the heat dissipation cover can be assembled according to the positioning information of the heat dissipation cover during the assembly process, making the assembly more accurate and meeting the assembly process requirements.

[0146] The following is an explanation of several major modules in the heat sink cover mounting device.

[0147] In one possible implementation, the conveyor track module b1 may include a conveyor track and a lifting and positioning module b4. The lifting and positioning module b4 is located between the loading and unloading ends of the conveyor track. The conveyor track receives a carrier at the loading end and transports the carrier above the lifting and positioning module b4.

After the heat dissipation cover of the chip within the carrier is assembled and packaged, the conveyor track transports the carrier to the unloading end of the conveyor track for unloading.

[0148] Combine Figure 30A and Figure 30B , the mounting module 2 provided by the present invention is explained.

[0149] Figure 30A is a schematic structural diagram of a mounting module provided in one embodiment of the present invention, Figure 30B is a cross-sectional view of a mounting module provided in one embodiment of the present invention, Figure 30C This is a front view of a mounting module provided in one embodiment of the present invention, Figures 30A to 30C As shown, the mounting module b2 provided by the present invention may include a negative pressure air supply component, a vacuum suction cup b21, an angle adjustment component, a pressure sensor b22, a transmission component, a conduction rod b23, and a spring b24.

[0150] The air pipe joint b251 of the negative pressure air supply component is connected to the air inlet of the vacuum suction cup b21 to provide negative pressure to the vacuum suction cup b21. In other words, the negative pressure air supply component provides negative pressure to the vacuum suction cup b21 through the air pipe joint b251.

[0151] The vacuum cup b21 is mounted on the first end of the transmission assembly. The second end of the transmission assembly abuts the first end of a spring b24. The second end of the spring b24 abuts the first end of a transmission rod b23. The second end of the transmission rod b23 abuts the pressure sensor b22. Thus, when the vacuum cup b21 attaches to the heat sink cover, the transmission assembly transmits pressure to the pressure sensor b22 via the spring b24, allowing the pressure sensor b22 to sense the pressure applied by the vacuum cup b21.

[0152] The angle adjustment assembly is in transmission connection with the vacuum suction cup b21, and drives the vacuum suction cup b21 to adjust its angle. In other words, the angle adjustment assembly can drive the vacuum suction cup b21 to rotate to adjust the angle of the vacuum suction cup b21 relative to the horizontal. For example, the angle adjustment assembly can drive the vacuum suction cup b21 to adjust its angle in a 360-degree angle.

[0153] In one possible implementation, the negative pressure air supply assembly may include an air pipe connector b251, a sealing cavity b252, and a sealing ring, wherein: the air pipe connector b251 enters the sealing cavity b252, the sealing cavity b252 is connected to the vacuum suction cup b21, and the sealing cavity b252 is sealed by the sealing ring.

[0154] The number of sealing rings can be set according to the actual situation of the sealing cavity b252, such as Figure 27 The third sealing ring b253 and the fourth sealing ring b254.

[0155] In one possible implementation, the transmission assembly may include a spline b26, which is a hollow structure. A through hole is provided on a predetermined section of the spline b26, and the predetermined section is provided in the sealing cavity b252. The sealing cavity b252 is connected to the vacuum suction cup b21 through the through hole and hollow structure of the spline b26.

[0156] The trachea connector b251 enters the sealed cavity b252, and the other end of the trachea connector b251 is connected to the load providing device, so that the load providing device will introduce the negative pressure into the sealed cavity b252 through the trachea connector b251; and because the spline b26 is a hollow structure and a through hole is provided in the part inside the sealed cavity b252, the negative pressure in the sealed cavity b252 can be connected to the vacuum suction cup b21, thereby realizing the adsorption control of the vacuum suction cup b21.

[0157] Optionally, the upper end of the spline b26 is abutted against the first end of the spring b24, and the up and down movement of the spline b26 is transmitted to the spring b24. The pressure generated by the deformation of the spring b24 is transmitted to the pressure sensor b22 through the conduction rod b23. That is to say, when the vacuum suction cup b21 adsorbs the heat sink cover, the spline b26 will transmit the pressure to the pressure sensor b22 through the spring b24. The pressure sensor b22 senses the magnitude of the pressure, thereby being able to monitor the pressure generated when the vacuum suction cup b21 adsorbs the heat sink cover in real time.

[0158] In order to facilitate the adjustment of the initial compression of the spring b24, the mounting module b2 provided by the present invention may further include a pre-pressure adjustment seat b27, which is installed above the pressure sensor b22 to adjust the initial compression of the spring b24.

[0159] In a possible implementation, the angle adjustment assembly may include a third servo motor b281, a third coupling b282, a first synchronous pulley b283, a belt, a second synchronous pulley b285, a transmission sleeve b286, and a rotating shaft b287.

[0160] The driving rod of the third servo motor b281 is connected to the first synchronous wheel b283 through the third coupling b282; the first synchronous wheel b283 is fixed to the first end of the rotating shaft b287, and the second synchronous wheel b285 and the transmission sleeve b286 are both fixed to the second end of the rotating shaft b287. The second synchronous wheel b285 and the transmission sleeve b286 rotate synchronously with the rotating shaft b287.

[0161] The belt is sleeved on the first synchronous wheel b283 and the second synchronous wheel b285, and the transmission sleeve b286 is sleeved and fixed on the spline b26 of the transmission component.

[0162] When the transmission assembly includes the above-mentioned spline B26, the transmission sleeve B286 mentioned here usually refers to the spline B26 sleeve.

[0163] In practical applications, it is usually necessary to tension the belt. In order to facilitate the adjustment of the belt tension, the angle adjustment assembly may further include a belt tensioning screw b288, which is used to adjust the tension of the belt.

[0164] Typically, the adsorption surface of the placement module b2 may be tilted after installation. In order to ensure process requirements, the placement module b2 provided in the present invention may further include a leveling component, which is transmission-connected to the vacuum suction cup b21 to adjust the horizontal angle of the vacuum suction cup b21.

[0165] In one possible implementation, placement module b2 may further include a bracket comprising an active bracket b296 and an adjustment bracket b297. The vacuum suction cup b21 is mounted on the active bracket b296. Furthermore, a negative pressure air supply assembly, an angle adjustment assembly, a pressure sensor b22, a transmission assembly, a conductive rod b23, a spring b24, and the like are also secured to the active bracket b296.

[0166] The leveling assembly may include a first leveling plate b291 and a second leveling plate b292. The first leveling plate b291 is mounted on an adjusting bracket b297 via an adjusting shaft b293. The adjusting bracket b297 is fixed to an active bracket b296 via the second leveling plate b292.

[0167] like Figure 30A and Figure 30C As shown, the leveling assembly can also include a first leveling screw b294 and a second leveling screw b295. The second leveling plate b292 is fixed with a first screw perforated seat and a second screw perforated seat above and below. The first leveling screw b294 passes through the first screw perforated seat and is inserted into the upper end of the first leveling plate b291. The second leveling screw b295 passes through the second screw perforated seat and is inserted into the lower end of the second leveling plate b292.

[0168] When the first leveling screw b294 is screwed toward the first leveling plate b291, it drives the first leveling plate b291 to rotate counterclockwise along the adjustment shaft b293; when the second leveling screw b295 is screwed toward the first leveling plate b291, it drives the second leveling plate b292 to rotate clockwise along the adjustment shaft b293.

[0169] See Figure 30D As shown, it is a schematic diagram of a vacuum suction cup provided in one embodiment of the present invention being leveled. Figure 30D As shown in (a), after leveling, Figure 30D As shown in (b) in .

[0170] The placement module provided by the present invention utilizes an angle adjustment component to precisely adjust the angle of the vacuum chuck, enabling the placement of heat sink covers of varying sizes. A pressure sensor monitors the pressure exerted by the vacuum chuck on the workpiece in real time, providing pressure feedback during placement. This not only meets process requirements but also avoids the risk of product damage during assembly. Furthermore, the high-precision angle adjustment component ensures assembly accuracy.

[0171] Combine Figure 31A and Figure 31B , the heat dissipation cover feeding device provided by the present invention is explained.

[0172] Figure 31A This is a structural diagram of a loading and unloading device for a heat dissipation cover carrier b3 provided in one embodiment of the present invention. Figure 31B This is a top view of the loading and unloading device of the heat dissipation cover support b3 provided in one embodiment of the present invention, combined with Figure 31A and Figure 31B The loading and unloading device of the heat dissipation cover carrier b3 provided by the present invention may include a loading part b31, a material picking and positioning part b32, a unloading part b33, and a first transverse movement component b34 spanning the loading part b31, the material picking and positioning part b32 and the unloading part b33.

[0173] After the loading part b31 lifts the heat dissipation cover carrier b35 into place, the first transverse movement component b34 moves the heat dissipation cover carrier b35 from the loading part b31 to the material picking and positioning part b32. The material picking and positioning part b32 positions and fixes the heat dissipation cover carrier b35. The material picking mechanism picks the heat dissipation cover on the heat dissipation cover carrier b35. The first transverse movement component b34 moves the heat dissipation cover carrier b35 after picking from the material picking and positioning part b32 to the unloading part b33.

[0174] Generally speaking, the material picking and positioning portion b32 is located between the loading portion b31 and the unloading portion b33 to reduce the moving stroke of the first transverse moving component b34, and the spatial arrangement is simple and the space utilization rate is high.

[0175] In one possible implementation, the loading section b31 may include a first lifting plate b32, a lifting positioning sensor b312, and a first lifting assembly b313. The first transverse movement assembly b34 includes a clamping cylinder and a clamping block b342. The lifting end of the first lifting assembly b313 is mounted on the first lifting plate b32, and the upper portion of the first lifting plate b32 is used to support the heat dissipation cover support b35. The driving end of the clamping cylinder is connected to the clamping block b342 to drive the clamping block b342 to open and close. The first lifting assembly b313 lifts the heat dissipation cover support b35 to the sensor, and the clamping cylinder drives the clamping block b342 to clamp the heat dissipation cover support b35.

[0176] The lifting and positioning sensor b312 mentioned here can be a photoelectric sensor, etc. The photoelectric sensor usually includes a light emitter and a light receiver installed relatively. When the heat dissipation cover carrier b35 is lifted between the light emitter and the photoelectric receiver, the light receiver will generate a changing electrical signal, thereby determining that the heat dissipation cover carrier b35 is lifted to the photoelectric sensor position.

[0177] Optionally, the first lifting assembly b313 may include a first lifting motor b3131, a first lifting guide rail b3132 and a first lifting screw b3133, the first lifting plate b32 is installed on the first lifting guide rail b3132 through a first slider b3134, the first lifting screw b3133 is installed between the first lifting motor b3131 and the first lifting plate b32, and the first lifting motor b3131 drives the first lifting plate b32 to move up and down along the first lifting guide rail b3132 through the first lifting screw b3133.

[0178] In practical applications, the heat dissipation cover carrier b35 can be a tray loading plate b3 that carries the heat dissipation cover, or it can be a clip that carries the heat dissipation cover.

[0179] Taking the heat dissipation cover carrier b35 as the Tray loading plate b3 as an example, the Tray loading plate b3 of the loading part b31 is located above the first lifting plate b32, and the Tray loading plate b3 carries the heat dissipation cover. The first lifting component b313 lifts the Tray loading plate b3 through the first lifting plate b32 to lift the Tray loading plate b3 to the position of the lifting positioning sensor b312; the loading part b31 also includes a first horizontal slide rail b314, and the Tray loading plate b3 is loaded along the first horizontal slide rail b314 under the action of external force to be directly above the first lifting plate b32.

[0180] In order to facilitate the operator to operate the Tray loading plate b3, a handle b36 can be fixedly installed on the end of the Tray loading plate b3. The operator acts on the Tray loading plate b3 by operating the handle b36 to realize pulling and pulling on the first transverse slide rail b314. Correspondingly, the Tray loading plate b3 is loaded along the first transverse slide rail b314 to the top of the first lifting plate b32 under the action of external force (usually refers to the force applied by the operator, of course, it can also be applied through other forms of mechanical force).

[0181] The material picking positioning part b32 may include multiple jacking positioning blocks b321, and the first transverse movement component b34 also includes a moving part b341 and a moving part b341 driving module. The clamping block b342 cylinder is fixedly installed on the moving part b341, and the moving part b341 driving module drives the moving part b341 to rotate. The moving part b341 drives the clamping cylinder and the clamping block b342 to move, so as to move the heat dissipation cover carrier b35 clamped by the clamping block b342 to above the jacking positioning block b321, and the jacking positioning block b321 rises and is inserted into the corresponding socket of the heat dissipation cover carrier b35 to realize the positioning and fixation of the heat dissipation cover carrier b35.

[0182] Optionally, a plurality of lifting positioning blocks b321 are respectively located at both ends of the material taking positioning portion b32 to ensure balanced force when positioning the heat dissipation cover support b35 and reduce the angular deviation of the heat dissipation cover support 35.

[0183] After the heat dissipation cover on the heat dissipation cover carrier b35 is removed, the moving part b341 drives the module to drive the moving part b341 to rotate to move the heat dissipation cover carrier b35 to the unloading part b33, and the clamping block b342 opens to release the heat dissipation carrier to the unloading part b33.

[0184] The movable part b341 mentioned here can be a belt, and the corresponding movable part b341 driving module can include a driver (such as a motor, etc.), a driving wheel, and a driven wheel. The driving wheel and the driven wheel are respectively arranged at intervals on the outside of the loading part b31 and the outside of the unloading part b33. The driving end of the driver is connected to the driving wheel, and the belt is wound around the driving wheel and the driven wheel. The driver drives the driving wheel to drive the belt to rotate between the loading part b31 and the unloading part b33.

[0185] The moving part b341 mentioned here can also be a lead screw. The corresponding moving part b341 driving module can drive the motor. The lead screw is installed at the driving end of the driving motor, and the driving motor drives the lead screw to rotate.

[0186] When the heat sink cover carrier b35 is a tray loading plate b3, the heat sink cover is typically placed directly on the tray loading plate b3, with no obstructions above or around the heat sink cover, allowing the picker head to directly pick up the heat sink cover from the tray loading plate b3. However, when the heat sink cover carrier b35 is a magazine, the heat sink cover is loaded in the magazine, so the picker head typically needs to first eject the heat sink cover from the magazine or lift it to the upper end of the magazine to allow the picker head to pick up the heat sink cover.

[0187] In order to be compatible with the heat sink cover loading method using a clip, please refer to Figure 31C and Figure 31D As shown, the material picking and positioning part b32 provided in the present invention can also include a jacking and loading assembly b322, which includes a loading motor b3221, a loading screw b3222, a lifting rod b3223, a second vertical guide rail b3224 and a synchronous belt. The loading motor b3221 is transmission-connected to the screw nut on the loading screw b3222, and the lifting rod b3223 is installed on the screw nut, which is installed on the second vertical guide rail b3224 through a slider. The loading motor b3221 drives the screw nut to move upward along the second vertical guide rail b3224, and the lifting rod b3223 lifts the heat dissipation cover in the magazine out of the magazine.

[0188] Still see Figure 31A and Figure 31B As shown, the unloading part b33 may include: a second lifting plate b331 and a second lifting assembly b332, wherein: the second lifting plate b331 is installed on the lifting end of the second lifting assembly b332, and the top of the second lifting plate b331 is used to support the heat dissipation cover supporting part b35 after the material is taken out; the second lifting assembly b332 drives the second lifting plate b331 to rise or fall.

[0189] Similarly, the second lifting assembly b332 may include a second lifting motor, a second lifting guide rail and a second lifting screw. The second lifting plate b331 is installed on the second lifting guide rail through a slider. The second lifting screw is installed between the second lifting motor and the second lifting plate b331. The second lifting motor drives the second lifting plate b331 to move up and down along the second lifting guide rail through the second lifting screw.

[0190] The heat dissipation cover carrier b35 is a Tray loading plate b3, and the unloading part b33 can also include a second slide rail b333. The Tray loading plate b3 is located above the second lifting plate b331. The second lifting assembly b332 drives the Tray loading plate b3 to descend after taking the material through the second lifting plate b331 to place the Tray loading plate b3 on the second slide rail b333. The Tray loading plate b3 moves along the second slide rail b333 under the action of external force to be pulled out from the unloading part b33.

[0191] In practical application, taking the heat dissipation cover carrier b35 as the Tray loading plate b3 as an example, first, the operator places the Tray loading plate b3 on the loading part b31, such as Figure 31E The tray loading plate b37 is pushed onto the lifting plate of the loading part b31. After the first lifting component b313 of the loading part b31 lifts the tray loading plate b37 to the position of the lifting positioning sensor b312, the tightening cylinder drives the clamping block b342 to clamp the tray loading plate b37; then the transverse module drives the tightening cylinder and the clamping block b342 to move transversely through the moving part b341, thereby moving the tray loading plate b37 to the material removal positioning part b32. Figure 31F As shown, the lifting positioning block b321 of the material positioning part b32 positions the Tray loading plate b37; the material head picks up the heat dissipation cover from the Tray loading plate b37. After the picking is completed, the transverse module continues to move the empty Tray loading plate b37 to the second lifting plate b331 of the unloading part b33, as shown in FIG. Figure 31G shown.

[0192] If the heat sink cover carrier b35 is a magazine, after the magazine is moved to the material positioning portion b32 and positioned, the lifting and loading assembly b322 will lift the heat sink cover inside the magazine to facilitate the material removal head to pick up the heat sink cover from the magazine. The rest of the workflow is similar to the tray loading plate b37.

[0193] The loading and unloading device for the heat dissipation cover carrier b3 provided by the present invention is provided with a first transverse movement assembly b3 spanning the loading portion b3, the material removal positioning portion b3, and the unloading portion b3. The first transverse movement assembly b3 moves the heat dissipation cover carrier b3 loaded at the loading portion b3 to the material removal positioning portion b3 for unloading. After unloading is completed, the empty heat dissipation cover carrier b3 is transported to the unloading portion b3 for unloading by the first transverse movement assembly b3. This achieves automatic loading and unloading of the heat dissipation cover carrier b3, avoids the need to stop the machine for loading or unloading, and ensures continuous operation of the production line. By providing a lifting loading assembly b3 at the material removal positioning portion b3, the loading and unloading device for the heat dissipation cover carrier b3 is compatible with the application of clip-type loading, meeting more usage requirements.

[0194] In summary, the heat dissipation cover mounting device provided by the present invention can position the absorbed heat dissipation cover by providing a positioning module, and then assemble the heat dissipation cover onto the chip in the carrier board, thereby improving the assembly accuracy of the heat dissipation cover.

[0195] In addition, when setting up the mounting module, the angle of the vacuum suction cup can be adjusted more accurately due to the angle adjustment component, which can meet the mounting requirements of heat sink covers of different sizes. By setting up a pressure sensor, the pressure of the vacuum suction cup on the adsorbed workpiece can be monitored in real time, and pressure feedback can be achieved during mounting. This not only meets the process requirements but also avoids the risk of product damage during assembly.

[0196] By arranging a first transverse movement component across the loading part, the material picking positioning part and the unloading part in the conveying track module, the heat dissipation cover carrier loaded in the loading part is moved to the material picking positioning part for material picking by the first transverse movement component. After the material picking is completed, the empty heat dissipation cover carrier is transported to the unloading part for unloading by the first transverse movement component, thereby realizing automatic loading and unloading of the heat dissipation cover carrier, avoiding the method of stopping the machine for loading or unloading, and providing guarantee for the continuous operation of the production line.

[0197] Figure 32 Schematic diagram of the structure of a hot pressing device provided in one embodiment of the present invention. The hot pressing device provided by the present invention may include a detection unit ( Figure 32 The figure shows a first detection part c100 and a second detection part c101), a heating and pressure maintaining part c20 and a conveying device c30.

[0198] In a possible implementation, there is one detection unit, which is disposed at a front-end station or a back-end station of the heating and pressure-maintaining unit c20.

[0199] In another possible implementation, Figure 32 As shown, there are two detection parts, which are respectively arranged at the front station and the back station of the heating and pressure holding part c20, and are the first detection part c100 and the second detection part c101.

[0200] In practical applications, the detection part can be set at the front-end station and / or the back-end station of the heating and pressure-maintaining part c20 according to analysis needs.

[0201] In actual production, the conveying device c30 conveys the carrier jig c40 loaded with the workpiece c50 to the detection part and the heating and pressure holding part c20.

[0202] The detection unit measures the height of the workpiece at at least one position on the workpiece c50 and detects the appearance of the workpiece c50.

[0203] The workpiece height mentioned here refers to the height difference between the height of a position on the workpiece c50 and the height of a position on the carrier jig c40 that is a predetermined distance away from the position.

[0204] For example, if the height at position A of workpiece c50 is Ha, and the height at position A' on carrier c40, a predetermined distance from position A, is ha, then the resulting workpiece height is Δha = ha - Ha. The predetermined distance can typically be set based on the dimensions of workpiece c50. Generally, the locations on workpiece c50 and carrier c40 used to calculate the workpiece height are closely spaced, resulting in a relatively low calculation error.

[0205] The heating and pressure-maintaining portion c20 heats and pressurizes the workpiece c50 located at the position of the heating and pressure-maintaining portion c20 .

[0206] See Figure 33 As shown, it is a structural schematic diagram of the detection part provided in one embodiment of the present invention. The detection part may include a second transverse movement component c11, a height measuring sensor head c12 and an AOI camera C13. The height measuring sensor head c12 and the AOI camera C13 are installed on the second transverse movement component c11, and move in the horizontal adjustment direction driven by the second transverse movement component c11. The horizontal adjustment direction is perpendicular to the conveying direction of the conveying device c30.

[0207] The height measuring sensor head c12 measures the height of a predetermined position of the workpiece c50 and a position on the carrier fixture c40 that is a predetermined distance away from the predetermined position; the AOI camera C13 takes photos to inspect the appearance of the workpiece c50.

[0208] In one possible implementation, Figure 32 As shown, there are two detection parts, namely a first detection part c100 located at the front station of the heating and pressure keeping part c20 and a second detection part c101 located at the back station of the heating and pressure keeping part c20.

[0209] The first detection unit c100 can measure the height of the workpiece at at least one position on the workpiece c50 and detect the appearance of the workpiece c50 to obtain a first set of detection data.

[0210] For example, the height measuring sensor head c12 measures the height of three positions (or multiple positions) of the workpiece c50 (height data H1, H2, H3...), and also measures the height of points close to the test points of the carrier fixture c40 and the workpiece c50 (height data h1, h2, h3...). For the test points, the maximum height of the workpiece is generated: (△h1, △h2, △h3...), where △h1 = h1-H1, △h2 = h2-H2, △h3 = h3-H3...

[0211] The second detection unit c101 can measure the height of the workpiece at at least one position on the workpiece c50 and detect the appearance of the workpiece c50 to obtain a second set of detection data.

[0212] For example, the height measuring sensor head c12 measures the height of three positions (or multiple positions) of the workpiece c50 (height data H1', ​​H2', H3'...), and also measures the height of points close to the test points of the carrier fixture c40 and the workpiece c50 (height data h1', h2', h3'...). The total height of the workpiece is generated for the test points: (△h1', △h2', △h3'...).

[0213] Typically, the hot pressing device also includes a processor electrically connected to the first detection part c100 and the second detection part c101. The processor determines whether the process of heating and pressing the workpiece c50 by the heating and pressing part c20 meets the requirements based on the first set of detection data and the second set of detection data.

[0214] Generally speaking, the second set of test data and the first set of test data have the same test position. Thus, whether the heating and pressure holding process meets the requirements can be determined based on the comparison between the first set of test data and the second set of test data.

[0215] For example, after heating and pressurizing, the rate of change of the workpiece height must be lower than a predetermined threshold. If the rate of change obtained by calculation based on the second set of test data and the first set of test data is lower than the predetermined threshold, it indicates that the heating and pressurizing process meets the requirements; otherwise, it is determined that the heating and pressurizing process does not meet the requirements.

[0216] In a possible implementation of the change rate here, the difference between the second set of detection data and the first set of detection data can be calculated, and the absolute value of the difference is divided by the first set of detection data to obtain the change rate.

[0217] In actual production, when it is detected that the appearance of the workpiece c50 is unqualified, it is usually necessary to discard these unqualified workpieces c50. Therefore, the detection part provided by the present invention can also include a transfer device and a recycling box. When the AOI camera C13 detects that the appearance of the workpiece c50 is unqualified, the transfer device transports the workpiece c50 and / or the carrier fixture c40 to the recycling box.

[0218] In summary, the hot pressing device provided by the present invention increases the judgment factors of the heating and pressing effect by adding AIO inspection of the workpiece height and appearance before and after the heating and pressing process, thereby improving the quality rate of workpiece packaging.

[0219] Among them, adding the appearance inspection of the workpiece before the heating and pressurizing process is convenient for directly eliminating defective workpieces, and only performing heating and pressurizing on qualified workpieces, thereby avoiding heating and pressurizing of defective workpieces and improving the quality rate of workpiece packaging; adding the appearance inspection of the workpiece after the heating and pressurizing process is convenient for eliminating defective workpieces with quality problems after heating and pressurizing, avoiding the flow of defective workpieces after heating and pressurizing into subsequent packaging processes, and further improving the quality rate of workpiece packaging; adding the appearance inspection of the workpiece and the workpiece height inspection before and after the heating and pressurizing process, so that the heating and pressurizing process can be analyzed based on the inspection data of the workpiece before and after heating and pressurizing, and the corresponding process, structure or parameters in the heating and pressurizing process can be optimized.

[0220] Figure 34 is a schematic structural diagram of a pressure loading device provided in one embodiment of the present invention, Figure 35 is a cross-sectional view of a pressure loading device provided in one embodiment of the present invention, Figure 34 and Figure 35 The pressure loading device d1 provided by the present invention may include a pressure device base plate d11, a low-friction cylinder d12, a linear bearing d13, a pressure guide rod d14, a heat-insulating workpiece pressure plate d15, a temperature sensor head d16, and a workpiece pressure plate anti-rotation plate d17. The installation relationship of each component is as follows:

[0221] The push rod of low-friction cylinder d12 is connected to the first end of pressure guide rod d14. Generally, pressure is applied downward when applying pressure to a workpiece. Therefore, the push rod of low-friction cylinder d12 is typically positioned vertically, that is, located above pressure guide rod d14 and connected to the first end of pressure guide rod d14.

[0222] The pressure guide rod d14 is installed in the bottom plate d11 of the pressure device and an insulating workpiece pressure plate d15 is installed at the second end of the pressure guide rod d14. The temperature sensor is installed on the pressure surface of the insulating workpiece pressure plate d15 to facilitate real-time testing of the temperature of the pressurized workpiece.

[0223] The linear bearing d13 is arranged in the bottom plate d11 of the pressure device, and the pressure guide rod d14 is accommodated in the linear bearing d13. The linear bearing d13 can support and guide the pressure guide rod d14.

[0224] The workpiece pressure plate anti-rotation plate d17 is installed below the bottom plate d11 of the pressure device, and the heat-insulating workpiece pressure plate d15 is accommodated in the anti-rotation groove of the workpiece pressure plate anti-rotation plate d17.

[0225] In a possible embodiment of the present invention, a low-friction cylinder d12 corresponds to a pressure guide rod d14, and an insulating workpiece pressure plate d15 is installed under each pressure guide rod d14. A temperature sensor is installed on the pressure surface of each insulating workpiece pressure plate d15. An insulating workpiece pressure plate d15 is typically used to apply pressure to a workpiece.

[0226] In order to ensure the installation and fixation of the low-friction cylinder d12, the pressure loading device d1 provided by the present invention may further include a cylinder mounting base plate d18, and the low-friction cylinder d12 is mounted on the cylinder mounting base plate d18.

[0227] Optionally, the pressure loading device d1 provided by the present invention may further include a connecting column d19, with both ends of the connecting column d19 respectively mounted on the cylinder mounting base plate d18 and the pressure device base plate d11.

[0228] In order to prevent the insulating workpiece pressing plate d15 from rotating during the process of pressing the workpiece, the insulating workpiece pressing plate d15 can be designed to be square, and the anti-rotation groove of the workpiece pressing plate anti-rotation plate d17 matches the shape of the insulating workpiece pressing plate d15.

[0229] In one possible implementation, see Figure 36 As shown, it is a schematic diagram of the air circuit control of the cylinder pressure principle provided in one embodiment of the present invention. The pressure loading device d1 provided by the present invention can also include an air storage tank d110 and an air cavity pipeline. The air storage tank d110 is connected to the air inlet of the low-friction cylinder d12 through the air cavity pipeline.

[0230] The air storage tank d110 can increase the air cavity in the circuit and reduce the impact of air pressure changes on the output pressure value of the cylinder.

[0231] The pressure loading device d1 can also include an electrical control unit and an electrical proportional valve d111. The electrical control unit is electrically connected to the electrical proportional valve d111. The electrical proportional valve d111 is installed on the air cavity pipeline. The electrical control unit controls the air pressure value at the outlet of the electrical proportional valve d111. The air pressure at the outlet of the electrical proportional valve d111 enters the low-friction cylinder d12, so that pressure is applied to the push rod of the low-friction cylinder d12.

[0232] In actual application, the pressure value of the electric proportional valve d111 is usually a set predetermined pressure, which is set according to the total weight of the pressure guide rod d14, the insulating workpiece pressure plate d15 and the temperature sensor head d16 and the pressure value applied to the workpiece.

[0233] The required pressure value for the workpiece is: the total weight G of the pressure guide rod d14, the square insulated workpiece pressure plate d15, and the temperature sensor head d16 plus the thrust of the cylinder. The required pressure value F for the workpiece is as follows:

[0234] F=G+Pa*S

[0235] Where F is the pressure applied to the workpiece, Pa is the pressure value set by the electric proportional valve d111, and S is the cylinder area of ​​the low-friction cylinder d12.

[0236] From the above formula, it can be seen that if the value of F needs to be adjusted, it can be changed by adjusting the pressure value set by the electrical proportional valve d111.

[0237] In summary, the pressure loading device provided by the present invention, by arranging a low-friction cylinder in the pressure loading device, realizes pressure on the workpiece through the thrust of the low-friction cylinder, solves the limitations when using weights to apply pressure to the workpiece, and reduces the weight of the pressure loading device; by arranging a temperature sensor head, the temperature of the pressurized workpiece can be measured in real time, and the temperature changes of the workpiece during the pressurization process can be controlled at any time.

[0238] In addition, by setting up an electric proportional valve, the pressure of the electric proportional valve can be set according to the total weight of the pressure guide rod, the insulating workpiece pressure plate and the temperature sensor head, and the pressure value applied to the workpiece, so that the air pressure value at the outlet of the electric proportional valve applied to the low-friction cylinder can be controlled, thereby reducing defective products caused by excessive or insufficient pressure.

[0239] Figure 37 is a schematic structural diagram of a workpiece pressure device provided in one embodiment of the present invention, Figure 38 is a cross-sectional view of a workpiece pressure device provided in one embodiment of the present invention, Figure 37 and Figure 38 The workpiece pressure device provided by the present invention may include a heating jacking component d2, a workpiece fixture component d3 and a pressure loading device d1. The pressure loading device d1 mentioned here can be referred to Figure 34 and Figure 35 It should be noted that the workpiece pressure device here is one of the structures of the heating and pressure maintaining part c20.

[0240] The workpiece fixture assembly d3 is located above the heating and lifting assembly d2 and is used to carry the workpiece to be pressurized.

[0241] The pressure loading device d1 is arranged opposite to the lifting end of the heating lifting assembly d2 and is used to apply pressure to the workpiece carried by the workpiece fixture assembly d3.

[0242] When the conveying mechanism conveys the workpiece fixture assembly d3 to the top of the heating and lifting assembly d2, the heating and lifting assembly d2 heats the workpiece in the workpiece fixture assembly d3 and lifts the workpiece fixture assembly d3 to the lower pressure surface of the pressure loading device d1. The low-friction cylinder d12 in the pressure loading device d1 pushes the pressure guide rod d14 to apply pressure to the workpiece, and the temperature sensor head d16 in the pressure loading device d1 senses the temperature on the workpiece.

[0243] Since the heating jacking component d2 has a heating effect on the workpiece, the workpiece pressure device provided by the present invention can also include a control unit. The temperature sensor head d16 is electrically connected to the control unit. When the temperature sensor head d16 detects that the temperature of the workpiece is not within the predetermined temperature range, that is, when the heating temperature of the workpiece is not suitable, the control unit can be used to adjust the heating value of the heating jacking component d2, so as to better monitor the production process.

[0244] Optionally, the electrical control unit in pressure-loading device d1 controls the air pressure at the outlet of electrical proportional valve d111, causing low-friction cylinder d12 to push pressure guide rod d14 at a constant pressure to apply pressure to the workpiece. Throughout the pressure application process, the pressure set by electrical proportional valve d111 remains constant, and the pressure on the workpiece also remains constant.

[0245] In actual application, when the conveying mechanism conveys the workpiece fixture assembly d3 to the top of the heating jacking assembly d2, the heating jacking assembly d2 heats the workpiece in the workpiece fixture assembly d3, and the heating jacking assembly d2 lifts the workpiece fixture assembly d3, so that the workpiece contacts the insulating workpiece pressure plate d15 of the pressure loading device d1, and then continues to lift it a predetermined distance so that the insulating workpiece pressure plate d15 pushes the pressure guide rod d14 to compress the push rod of the low-friction cylinder d12, so that the pressure of the low-friction cylinder d12 is applied to the workpiece.

[0246] To sum up, the workpiece pressing equipment provided by the present invention, by arranging a low-friction cylinder in the pressure loading device, realizes pressure on the workpiece through the thrust of the low-friction cylinder, solves the limitations when using weights to pressurize the workpiece, and reduces the weight of the pressure loading device; by arranging a temperature sensor head, the temperature of the pressurized workpiece can be measured in real time, and the temperature changes of the workpiece during the pressurization process can be controlled at any time.

[0247] In addition, by setting up an electric proportional valve, the pressure of the electric proportional valve can be set according to the total weight of the pressure guide rod, the insulating workpiece pressure plate and the temperature sensor head, and the pressure value applied to the workpiece, so that the air pressure value at the outlet of the electric proportional valve applied to the low-friction cylinder can be controlled, thereby reducing defective products caused by excessive or insufficient pressure.
