Description

Technical Field

[0001] This invention relates to the field of pressure holding equipment technology, specifically to a quick-change pressure holding device. Background Technology

[0002] In the manufacturing process of precision components such as electronic components and semiconductor devices, the pressure holding process is one of the core steps to ensure the performance and structural stability of the components. Whether it is the curing of molding compound in chip packaging, the lamination and bonding of flexible circuit boards, or the assembly and fixing of sensor components, specific pressure must be applied and maintained for a preset time to ensure that the components are tightly bonded together, avoiding defects such as delamination, bubbles, and displacement, thereby ensuring that the electrical performance and mechanical strength of the components meet the design standards.

[0003] In pressure holding operations, the pressure head is a key component for achieving precise pressure holding. The pressure head acts directly on the pressure-bearing part of the component. Its end face profile, material hardness, and pressure transmission characteristics need to be customized according to the pressure requirements of the component. For example, a flexible buffer pressure head is required for fragile ceramic components, while a flat rigid pressure head is required for large-area planar components to achieve uniform pressure application.

[0004] However, existing pressure-holding presses generally suffer from poor compatibility. The pressure head connection interfaces of traditional presses are mostly special structures, making it difficult to directly adapt to pressure heads of different shapes and functions. When replacing the pressure head, it is often necessary to replace the connection components, which further increases the complexity of equipment adjustment and production costs.

[0005] This lack of compatibility means that companies producing a variety of small-batch components need to equip themselves with multiple presses of different specifications to correspond to different combinations of carrier boards and press heads. This not only significantly increases the cost of equipment purchase and site investment, but also reduces the space utilization rate and production changeover efficiency of the production line. At the same time, frequent disassembly and adjustment of carrier boards and press heads will also increase the probability of equipment failure and the intensity of manual operation, which is not conducive to achieving efficient and precise large-scale production.

[0006] Therefore, developing a pressure-holding press that is compatible with multiple pressure heads and enables rapid switching and precise execution of pressure-holding processes for components of different specifications has become an urgent technical problem to be solved in this field.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0024] Example: See Figures 1 to 9As shown, this embodiment provides a quick-change pressure-holding device, which includes: a machine base 100; a transmission mechanism 200, wherein a tray containing components to be pressure-held moves along the transmission mechanism 200; a quick-change pressure-holding mechanism 300, the quick-change pressure-holding mechanism 300 including: a pressure-holding base frame 310, the pressure-holding base frame 310 being disposed above the machine base 100; a first mounting frame 320, the first mounting frame 320 including a first top plate 321 and a first bottom plate 322 disposed vertically at intervals, the first top plate 321 being connected to the pressure-holding base frame 310, the first bottom plate 322 being located above the transmission mechanism 200, and having a first clearance groove thereon; a pressure plate locking assembly 330, the pressure plate locking assembly 330 including a first locking driver 331, a first locking plate 333, and a first track 334, the first locking driver 331 being disposed on the first top plate 321, the first locking plate 333 being located between the first top plate 321 and the first bottom plate 322, and ... The first locking plate 333 is connected to the power output end of the first locking driver 331 to move vertically. The first track 334 is connected to the side of the first locking plate 333 facing the transmission mechanism 200. It can pass through the first clearance groove to the bottom of the first base plate 322. The bottom surface of the first track 334 is provided with a through groove extending along its length. The connector on the pressure holding fixture to be replaced can pass through the through groove horizontally into the first track 334, and can be locked in the first track 334 by the first base plate 322 through the lifting of the first locking plate 333. The lifting mechanism 400 is arranged on the transmission path of the transmission mechanism 200 and located below the quick-change pressure holding mechanism 300. It includes a lifting driver 410. The tray containing the pressure holding component can be connected to the power output end of the lifting driver 410 to move vertically towards the pressure holding fixture after replacement.

[0025] It should be noted that, in this embodiment, the pressure-holding fixture to be replaced is provided with a "T"-shaped connector at its top, which can pass through the through slot into the first track 334. It can be horizontally inserted into the first track 334 by an external moving device, such as a robotic arm or a crane.

[0026] The machine base 100 is the basic support structure of the entire equipment. It supports all core components such as the transmission mechanism 200, the quick-change pressure-holding mechanism 300, and the lifting mechanism 400, providing a stable installation benchmark and working platform for the equipment and ensuring that each mechanism is accurately positioned and does not wobble significantly during operation. Specifically, in this embodiment, the machine base 100 is provided with a slide rail 110, which extends in the same direction as the first track 334. The pressure-holding base frame 310 is slidably connected to the slide rail 110 to improve the flexibility and applicability of the quick-change pressure-holding mechanism 300.

[0027] In this embodiment, the transmission mechanism 200 precisely moves the carrier board to directly below the quick-change pressure-holding mechanism 300 via a preset transmission path. After completing the pressure-holding operation, the carrier board is then transported to the next process. It is crucial for connecting upstream and downstream processes, automating the pressure-holding process of components and improving overall work efficiency. Furthermore, in this embodiment, the transmission mechanism 200 is configured as a transmission line capable of interfacing with adjacent workstations.

[0028] In the quick-change pressure-holding mechanism 300, the pressure-holding base frame 310 is the supporting skeleton structure of the quick-change pressure-holding mechanism 300. It is slidably connected to the slide rail 110 on the machine base 100, which is used to fix the first mounting frame 320, providing a stable mounting position for the first mounting frame 320, and simultaneously ensuring the relative positional accuracy of the first mounting frame 320 with the lower transmission mechanism 200 and lifting mechanism 400. Specifically, the quick-change pressure-holding mechanism 300 in this embodiment has two pressure-holding processing spaces, which are arranged at intervals along the transmission direction of the transmission mechanism 200, thereby further improving the pressure-holding efficiency.

[0029] The first mounting bracket 320 consists of a first top plate 321 and a first bottom plate 322, which are spaced apart vertically. The first top plate 321 is equipped with a first locking driver 331, which provides a power mounting fulcrum for the pressure plate locking assembly 330 and also plays a guiding and limiting role in the vertical movement of the first locking plate 333. The first top plate 321 and the first bottom plate 322 are fixedly connected by a support column. The first bottom plate 322 is located above the transmission mechanism 200 and serves as the bearing and limiting reference for the pressure holding fixture. The first clearance groove on the bottom plate allows the first track 334 to pass through, providing a channel for the vertical movement of the first track 334. On the other hand, when the pressure holding fixture is fixed, the edge of the first clearance groove forms a horizontal limit on the first track 334, preventing the pressure holding fixture from horizontally displacing during the pressure holding process.

[0030] The pressure plate locking assembly 330 consists of a first locking driver 331, a first locking plate 333, and a first track 334. The first locking driver 331 serves as a power source and is installed on the first top plate 321. Its power output end is connected to the first locking plate 333, which can drive the first locking plate 333 to rise and fall vertically, thereby driving the first track 334 to rise and fall synchronously. It is the core power source for realizing the disassembly and locking of the fixture. Furthermore, the pressure plate locking assembly 330 in this embodiment also includes a transmission unit 332. The transmission unit 332 includes two connecting blocks 3322 and three connecting rods 3321. The three connecting rods 3321 are rotatably connected to each other in sequence. One connecting block 3322 is placed on the first top plate 321, and another connecting block 3322 is disposed on the first locking plate 333. One connecting rod 3321 located at the end is rotatably connected to the power output end of the first locking driver 331, and the other connecting rod 3321 located at the end is rotatably connected to the connecting block 3322 on the first locking plate 333. The connecting block 3322 disposed on the first top plate 321 is connected to the rotatable connection of the connecting rod 3321.

[0031] Specifically, the transmission unit 332 smoothly and efficiently transmits the power of the first locking driver 331 to the first locking plate 333, ensuring that the first locking plate 333 drives the first track 334 to achieve precise and controllable vertical lifting and lowering, providing a reliable guarantee for the stable locking and rapid unlocking of the pressure-holding fixture. The two connecting blocks 3322 respectively serve the functions of fixing and supporting movement. The connecting block 3322 placed on the first top plate 321 is connected to the rotational connection of the three connecting rods 3321, becoming the fixed hinge reference for the entire transmission unit 332, providing stable support for the rotation of the connecting rods 3321, effectively limiting the trajectory deviation of the linkage mechanism during power transmission, and ensuring the accuracy of the movement direction. The connecting block 3322 set on the first locking plate 333 is rotatably connected to one end connecting rod 3321, serving as the motion hinge fulcrum of the linkage mechanism, responsible for receiving the power transmitted by the connecting rods 3321, and smoothly converting the planar rotation of the connecting rods 3321 into the vertical linear motion of the first locking plate 333, achieving efficient conversion of power form. Three sequentially rotatably connected links 3321 constitute the core carrier of power transmission, forming a multi-link linkage mechanism. One link 3321 at one end is directly rotatably connected to the power output end of the first locking actuator 331, receiving the extension and retraction power output by the actuator and converting this linear power into its own rotational motion. Subsequently, through the sequential rotational engagement between the three links 3321, power is smoothly transmitted from the input end to the other end link 3321 connected to the connecting block 3322 of the first locking plate 333. During the transmission process, the multi-link structure effectively optimizes the dynamics. The force transmission path reduces power loss, and the displacement or force of the power output can be amplified or reduced according to actual working needs, so that the lifting speed and force of the first locking plate 333 are more in line with the pressure requirements when locking the pressure holding fixture. In addition, this multi-link linkage design can significantly improve the stability of the lifting process of the first locking plate 333, avoid problems such as tilting or jamming of the first locking plate 333 that may be caused by single-point drive, and thus ensure that the first track 334 connected to the first locking plate 333 can be accurately aligned with the first clearance groove on the first base plate 322, laying the foundation for reliable locking of the pressure holding fixture.

[0032] The first locking plate 333 connects the first locking actuator 331 and the first track 334, serving as a power transmission and connection mechanism. It receives power from the actuator and drives the first track 334 to complete its lifting and lowering motion, while simultaneously restricting the horizontal freedom of the first track 334 to ensure precise movement. Correspondingly, the first track 334 is a key component connecting the pressure-holding fixture. During the quick fixture change phase, the first locking actuator 331 drives the first locking plate 333 upward, causing the first track 334 to descend and disengage from the first clearance groove of the first base plate 322. At this time, the first track 334 is in the unlocked state. External mobile equipment can insert the "T"-shaped connector of the pressure-holding fixture to be replaced horizontally into the through groove on the bottom surface of the first track 334, or remove the old fixture from the through groove, achieving quick fixture assembly and disassembly. After the fixture replacement is completed, the first locking actuator 331 drives the first locking plate 333 upward, causing the first track 334 to rise into the first clearance groove. At this time, the edge of the first clearance groove forms a horizontal limit on the first track 334.

[0033] Furthermore, the pressure plate locking assembly 330 in this embodiment also includes a first limiting member 335. The first limiting member 335 is located at the horizontal extension end of the first track 334. The connector on the pressure-holding fixture to be replaced can move horizontally in the first track 334 until it abuts against the first limiting member 335. When the external mobile device moves the "T"-shaped connector of the pressure-holding fixture horizontally into the track along the through groove on the bottom surface of the first track 334, the connector can slide along the length direction in the track until it abuts against the first limiting member 335. At this time, the connector's freedom of horizontal movement is restricted, thereby ensuring that the pressure-holding fixture replaced each time can accurately stop at the preset working position, avoiding the impact of fixture installation position deviation on the subsequent pressure-holding accuracy of components, and also preventing the connector from horizontally shifting in the track, further improving the stability of the pressure-holding fixture after locking. In this embodiment, the first limiting member 335 is preferably an elastic limiting pin. In different implementations, it can also be configured as a limiting plate, elastic member or other structures according to actual applicable needs. This invention does not impose specific restrictions on this.

[0034] In this embodiment, in order to further improve the quick-change accuracy of the pressure-holding fixture, the quick-change pressure-holding device also includes a guide assembly 340. The guide assembly 340 includes a guide frame 341 and a fixture track 342. The guide frame 341 is disposed on one side of the width direction of the first mounting frame 320. The fixture track 342 is connected to the guide frame 341, extends in the same direction as the first track 334, and is located below the first track 334. The fixture track 342 is provided with a plurality of rollers 3421, and the pressure-holding fixture to be replaced can be slidably supported on the rollers 3421. The guide frame 341 provides a stable support reference for the fixture track 342, while ensuring the relative positional accuracy of the fixture track 342 and the first track 334 extending in the same direction. The fixture track 342 is connected to the guide frame 341 and located below the first track 334. Multiple rollers 3421 arranged on it can provide sliding support for the pressure-holding fixture to be replaced. When the external mobile device drives the "T"-shaped connector of the pressure-holding fixture to move horizontally along the through groove of the first track 334, the bottom of the pressure-holding fixture slides synchronously against the rollers 3421. The rolling friction of the rollers 3421 replaces the sliding friction between the fixture and the track, which greatly reduces the resistance when the fixture moves and avoids jamming or sticking during quick replacement. At the same time, in conjunction with the limiting effect of the first track 334, it ensures that the fixture always moves smoothly in the preset direction, further improving the smoothness and positional accuracy of the quick replacement operation of the pressure-holding fixture.

[0035] Furthermore, the quick-change pressure-holding device includes two guide components 340, which are symmetrically arranged on both sides of the width direction of the first mounting frame 320. Each guide component 340 also includes a side pusher 343 and a side pusher driver 344. The side pusher driver 344 is located on the side of the guide frame 341 away from the first track 334. The side pusher 343 is connected to the side pusher driver 344 and can pass through the side through hole of the guide frame 341 to abut against the pressure-holding fixture to be replaced. The symmetrical arrangement of the two guide components 340 allows for simultaneous force application from both sides of the fixture, ensuring uniform positioning force. A side push driver 344 is installed on the side of the guide frame 341 away from the first track 334, serving as the power source for the side push operation. Its power output end is connected to the side push member 343. When the external mobile device moves the pressure-holding fixture onto the roller 3421 of the fixture track 342 and slides along the track to a position close to the first limit member 335, the side push drivers 344 on both sides simultaneously drive the side push member 343 through the guide frame. The side through hole on 341 extends towards the fixture until the side pusher 343 abuts against the side wall of the pressure holding fixture. Using the thrust of the two side pushers 343, the pressure holding fixture is precisely pushed to the preset center position, eliminating the positional deviation of the fixture in the horizontal direction. This ensures that the "T"-shaped connector on the fixture can be accurately aligned with the through groove of the first track 334. At the same time, it ensures that after the fixture is locked, it is in a coaxial corresponding state with the components on the lower lifting mechanism 400 and the carrier plate, providing a reliable guarantee for the accuracy of the subsequent pressure holding process.

[0036] In this embodiment, the lifting mechanism 400 is located on the transmission path of the transmission mechanism 200 and directly below the quick-change pressure-holding mechanism 300. Its core function is to drive the carrier plate upward to achieve pressure holding of the components. The lifting driver 410 serves as a power source, with its power output end connected to the carrier plate. When the carrier plate is moved to the pressure-holding working position by the transmission mechanism 200, the lifting driver 410 drives the carrier plate to rise vertically, causing the components to be pressure-held on the carrier plate to approach and adhere to the locked pressure-holding fixture. Pressure is applied through the contact between the pressure-holding fixture and the components to complete the pressure-holding process. After pressure holding is completed, the lifting driver 410 drives the carrier plate to descend back to the transmission surface of the transmission mechanism 200, where it is transported to the next process by the transmission mechanism 200. When it is necessary to replace the pressure-holding fixture, the first locking driver 331 drives the first track 334 to move upward and disengage from the first clearance groove, thereby unlocking and disassembling the fixture. After the fixture is installed, the first track 334 moves downward and enters the first clearance groove, where it is locked by the first base plate 322. At this time, the transmission mechanism 200 sends the carrier plate to the working position, and the lifting mechanism 400 lifts the carrier plate so that the components and the pressure holding fixture are in contact to complete the pressure holding process, thereby realizing one pressure holding process.

[0037] It should be noted that the carrier tray of the component to be held under pressure needs to be supported on the carrier plate. Therefore, the carrier plate needs to undergo the same quick-change processing for different carrier trays. In this embodiment, the lifting mechanism 400 further includes: a second mounting frame 420, which includes a second top plate 421 and a second bottom plate 422 arranged vertically at intervals. The second bottom plate 422 is connected to the lifting driver 410, and the second top plate 421 is provided with a second clearance groove 4211; and a lifting locking assembly 430, which includes a second locking driver 431, a second locking plate 432, and a second track 433. The second locking driver 431 is disposed on the second bottom plate 422, and the second locking plate 432 is located between the second top plate 421 and the second bottom plate. Between 422, and the second locking plate 432 is connected to the power output end of the second locking driver 431 to move in the vertical direction, the second track 433 is connected to the side of the second locking plate 432 facing the transmission mechanism 200, and it can pass through the second clearance groove 4211 to the top of the second top plate 421. The bottom surface of the second track 433 is provided with a through groove extending along its length direction. The connector on the carrier plate to be replaced can pass through the through groove in the horizontal direction into the second track 433, and can be locked in the second track 433 by the second top plate 421 through the lifting of the second locking plate 432.

[0038] Specifically, the second mounting frame 420 consists of a second top plate 421 and a second bottom plate 422 spaced vertically. The second bottom plate 422 is connected to the power output end of the lifting driver 410, receiving the power of the lifting driver 410 and driving the entire second mounting frame 420 and the carrier plate to move up and down synchronously. The second clearance groove 4211 opened on the second top plate 421 provides a channel for the vertical movement of the second track 433. The lifting locking assembly 430 includes a second locking driver 431, a second locking plate 432, and a second track 433. The second locking driver 431 is mounted on the second bottom plate 422, and its power output end is connected to the second locking plate 432, which can drive the second locking plate 432 vertically between the second top plate 421 and the second bottom plate 422. Moving in a straight direction, the second track 433 is connected to the side of the second locking plate 432 facing the transmission mechanism 200. It can pass through the second clearance groove 4211 and extend above the second top plate 421 as the second locking plate 432 moves. The bottom surface of the second track 433 has a through groove extending along its length. The connector on the carrier plate to be replaced can pass through the through groove in a horizontal direction into the second track 433. When the second locking driver 431 drives the second locking plate 432 to rise, the second track 433 moves upward accordingly. The upper surface of the second top plate 421 will press down on the second track 433, thereby firmly locking the carrier plate connector passing through the second track 433, thus completing the quick-change and fixing of the carrier plate and adapting to the support requirements of different specifications of carrier plates.

[0039] Furthermore, in this embodiment, the first base plate 322 is provided with a first positioning pin 3221 on the side facing the transmission mechanism 200. The first positioning pin 3221 can be inserted into the pressure-holding fixture to be replaced. The second top plate 421 is provided with a second positioning pin 4212 on the side facing the transmission mechanism 200. The second positioning pin 4212 can be inserted into the carrier plate to be replaced. The lifting and locking assembly 430 also includes a second limiting member 434, which is located at the horizontal extension end of the second track 433. The connecting member on the carrier plate to be replaced can move horizontally within the second track 433 until it abuts against the second limiting member 434. Its function and principle are the same as those of the pressure plate locking assembly 330, and will not be elaborated further here.

[0040] In this embodiment, the quick-change pressure-holding device further includes a carrier plate buffer platform 500. The carrier plate buffer platform 500 includes a platform body 510 and a carrier plate track 520. The platform body 510 is disposed on the machine base 100 and located on the feeding side of the lifting mechanism 400. The carrier plate track 520 is disposed on the upper surface of the platform body 510 and extends in the same direction as the first track 334. The carrier plate to be replaced can be moved from the carrier plate track 520 to the second track 433.

[0041] The carrier plate buffer platform 500 is an auxiliary storage and transfer structure for efficient and rapid carrier plate replacement. The platform body 510 is mounted on the machine base 100 and located on the feeding side of the lifting mechanism 400, serving as the mounting base for the carrier plate track 520 and ensuring that the carrier plate track 520 and the second track 433 of the lifting mechanism 400 maintain a corresponding position. The carrier plate track 520 is laid on the upper surface of the platform body 510 and extends in the same direction as the first track 334, ensuring that the track extension direction is consistent with the carrier plate transfer path. When it is necessary to replace a carrier plate adapted to different pallets, the carrier plate to be replaced can be temporarily placed on the carrier plate track 520. Subsequently, it is pushed smoothly along the carrier plate track 520 by external mobile equipment or other power sources, accurately moving into the second track 433 of the lifting mechanism 400 without additional adjustment of the carrier plate transfer direction. This effectively shortens the carrier plate replacement time, improves the equipment's adaptability to different specifications of pallets, and avoids damage caused by random placement of the carrier plate to be replaced, ensuring the structural integrity of the carrier plate.

[0042] In addition, the quick-change pressure-holding device in this embodiment also includes a re-inspection mechanism 600. The re-inspection mechanism 600 includes a re-inspection module 610 supported on the machine base 100 and a re-inspection camera 620 slidably disposed on the re-inspection module 610. Further, the re-inspection module 610 in this embodiment includes a vertical moving track and a horizontal moving track to realize the two-dimensional movement process of the re-inspection camera 620.

[0043] The quick-change pressure-holding device in this embodiment also includes a control mechanism. The transmission mechanism 200, the quick-change pressure-holding mechanism 300, the lifting mechanism 400, and the re-inspection mechanism 600 are respectively connected to the control mechanism. In actual production and processing, operators can adjust the above structure in real time through the control mechanism, thereby improving the flexibility of the equipment. Parameters can also be preset through the control mechanism, thereby improving the automation level of the equipment.

[0044] In summary, the quick-change pressure-holding device of this invention enables quick-change assembly of different pressure-holding fixtures via the quick-change pressure-holding mechanism 300. The pressure plate locking assembly 330 and the first mounting bracket 320 have a clever structural fit. When a quick change of pressure-holding fixture is required, the first track 334 disengages from the first clearance groove on the first base plate 322 to facilitate the disassembly and assembly of the pressure-holding fixture. After movement, the first track 334 can be driven back into the first clearance groove, where the edge of the first clearance groove limits its movement, thus fixing the pressure-holding fixture. Compared to conventional pressure-holding equipment, this invention can replace pressure-holding fixtures quickly without affecting the normal processing rhythm of the production line, and also boasts advantages such as simple operation, strong controllability, high precision, and high automation.

[0045] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
