Description

A modular pressure holding device Technical Field

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

[0002] During the production and processing of some precision electrical components, it is usually necessary to apply pressure to improve the compaction and curing of the internal materials, so as to prevent them from becoming loose due to vibration during later use.

[0003] The common method of pressure holding is manual. The specific procedure involves the operator placing the product to be pressured on the pressure holding equipment and manually operating it to complete the pressure holding process. This method is inefficient, labor-intensive, and not suitable for continuous operation along the production line. While existing pressure holding equipment can automate the pressure holding process, the product typically has multiple independent pressure holding positions. The equipment must sequentially perform pressure holding operations on each position, significantly reducing efficiency and flexibility. Therefore, a solution is urgently needed. Summary of the Invention

[0004] To avoid and overcome the technical problems existing in the prior art, the present invention provides a modular pressure holding device. The present invention uses various pressure holding modules to independently partition and hold pressure in different areas of the material tray, which can effectively improve the pressure holding efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A modular pressure-holding device includes a base for horizontally fixing a material tray, on which various components to be pressure-held are arranged in a rectangular array. Above the material tray, multiple sets of pressure plates are arranged, and each pressure plate has multiple pressure-holding airbags that correspond one-to-one with the corresponding components to be pressure-held. The pressure-holding airbags on each set of pressure plates cooperate to form a rectangular array distribution identical to that of the components to be pressure-held on the material tray. Each set of pressure plates is equipped with a pressure-holding telescopic component that can drive the pressure plates to press the components to be pressure-held.

[0007] As a further embodiment of the present invention: the pressure-holding telescopic assembly includes a pressure-holding telescopic rod fixedly installed on a support frame, and the telescopic direction of the pressure-holding telescopic rod is arranged vertically, with a pressure plate fixedly installed on the telescopic end of the pressure-holding telescopic rod.

[0008] As a further embodiment of the present invention: the pressure-holding telescopic assembly also includes guide cylinders fixed on the support frame, and each guide cylinder is arranged sequentially around the pressure-holding telescopic rod in the circumferential direction; and the axial direction of each guide cylinder is parallel to the telescopic direction of the pressure-holding telescopic rod; each guide cylinder has a guide rod slidably installed coaxially inside it, and the bottom of each guide rod is fixed to the upper plate surface of the pressure plate.

[0009] As a further embodiment of the present invention: the top ends of each guide rod are fixed on the same fixing ring, and the fixing ring is sleeved on the outside of the pressure-holding telescopic rod.

[0010] As a further embodiment of the present invention: the telescopic end of the pressure-holding telescopic rod is fixedly connected to a mounting plate arranged horizontally on the plate surface. Guide holes are provided at the four corners of the mounting plate, and a T-shaped guide pin is coaxially inserted into each guide hole. The bottom end of the guide pin is fixed to the upper plate surface of the pressure plate. A buffer spring is coaxially sleeved on the guide pin located between the pressure plate and the mounting plate, and a correction gap is formed between the guide pin and the guide hole to allow the guide pin to tilt.

[0011] As a further aspect of the present invention, a pressure sensor for detecting the downward pressure of the telescopic rod is sandwiched between the telescopic end of the pressure-holding telescopic rod and the mounting plate.

[0012] As a further aspect of the present invention, the pressure-holding telescopic rod is a drive electric cylinder.

[0013] As a further embodiment of the present invention: there are four guide cylinders, which are arranged symmetrically with the axis of the drive electric cylinder as the axis of symmetry.

[0014] As a further aspect of the present invention: each pressure-holding airbag is connected to an air pump.

[0015] As a further aspect of the present invention, the pressure-holding and telescopic components consist of six sets.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This modular pressure-holding equipment uses a horizontally fixed base to hold material trays, enabling the orderly rectangular array placement of parts to be pressured, facilitating batch processing and operation. Multiple pressure plates correspond one-to-one with the parts to be pressured on the material trays, working in conjunction with pressure-holding airbags to achieve precise pressure holding, improving pressure-holding efficiency and accuracy. The rectangular array distribution not only optimizes space utilization but also ensures the uniformity and consistency of the pressure-holding process. The introduction of pressure-holding telescopic components allows the pressure plates to flexibly clamp the parts to be pressured, enhancing the adaptability and controllability of the equipment.

[0018] 2. The pressure-holding telescopic assembly adopts a vertically arranged pressure-holding telescopic rod, with the pressure plate fixed to the telescopic end. This design simplifies the execution of the pressure-holding action, ensures stable vertical movement of the pressure plate, and improves the accuracy and reliability of pressure holding. At the same time, the structure fixedly mounted on the support frame also enhances the overall stability and durability of the equipment.

[0019] 3. The introduction of the guide cylinder, in conjunction with the pressure-holding telescopic rod, provides additional guidance and support for the pressure plate, effectively preventing its deviation and swaying during movement. The sliding fit between the guide cylinder and the guide rod ensures the smoothness and linearity of the pressure plate's movement, further improving the pressure-holding effect and the equipment's operational stability.

[0020] 4. The top of each guide rod is fixed on the same fixing ring, and the fixing ring is sleeved on the outside of the pressure-holding telescopic rod. This design not only simplifies the installation and debugging of the guide structure, but also enhances the integrity and rigidity of the guide system, making the pressure plate more stable and reliable during movement.

[0021] 5. The cooperation between the guide pin and the buffer spring provides the pressure plate with automatic correction capability. Even if a slight deviation occurs during use, it can quickly return to its original position due to the elasticity of the buffer spring, ensuring the accuracy and stability of the pressure holding process. At the same time, the correction gap between the guide pin and the guide hole also allows for a certain degree of freedom, improving the fault tolerance of the equipment.

[0022] 6. The introduction of pressure sensors enables the equipment to monitor the downward pressure of the pressure-holding telescopic rod in real time, providing operators with accurate feedback data to facilitate timely adjustments to pressure-holding parameters and ensure the stability and consistency of the pressure-holding effect. This also makes automated control and remote monitoring of the equipment possible.

[0023] 7. The pressure-holding telescopic rod uses a drive electric cylinder, which not only improves the response speed and accuracy of the pressure-holding action, but also reduces the energy consumption and maintenance costs of the equipment. The electric cylinder's driving method is more environmentally friendly and efficient, in line with the development trend of modern industrial automation.

[0024] 8. The guide cylinders are arranged symmetrically with the axis of the drive electric cylinder as the axis of symmetry. This design is not only aesthetically pleasing but also enhances the structural symmetry and stability of the equipment. The arrangement of the four guide cylinders also ensures that the pressure plate receives uniform guidance and support in four directions, further improving the pressure holding effect.

[0025] 9. Each pressure-holding airbag is connected to an air pump, enabling independent control and adjustment of the airbags. This design allows the equipment to flexibly adjust the pressure and time of each airbag according to the different requirements of the components to be pressure-held, improving the flexibility and adaptability of the equipment.

[0026] 10. The pressure-holding telescopic assembly has six sets. This multi-set design not only improves the pressure-holding capacity and efficiency of the equipment, but also enhances its stability and reliability. The six sets of pressure-holding telescopic assemblies can work simultaneously or independently, meeting pressure-holding requirements of different scales and complexities, and providing strong support for the widespread application of the equipment.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please refer to Figures 1 and 2. In this embodiment of the invention, a modular pressure-holding device includes a base 1 and a support frame mounted on the base 1. A limiting groove for placing a material tray 2 is located on the base 1. The shape of the limiting groove is adapted to the shape of the material tray 2, thereby stably and horizontally placing the material tray 2 in the limiting groove and preventing it from moving during the pressure-holding process.

[0032] The pressure-holding components 21 are placed in the material trough on the material tray 2, and each pressure-holding component 21 is placed in a rectangular array on the material tray 2.

[0033] Six sets of pressure-holding telescopic components 4 are installed on the support frame, and each set of pressure-holding telescopic components 4 has a horizontally arranged pressure plate 3 installed at its actuating end. Each pressure plate 3 has multiple pressure-holding airbags 31 that correspond one-to-one with the corresponding pressure-holding component 21. The pressure-holding airbags 31 on each set of pressure plates 3 cooperate to form a rectangular array distribution identical to that of the pressure-holding components 21 on the material tray 2, thereby providing full coverage pressure holding for the pressure-holding components 21 on the material tray 2. Each pressure-holding airbag 31 is connected to an air pump, enabling independent control and adjustment of the pressure-holding airbag 31. This design allows the equipment to flexibly adjust the pressure holding pressure and time of each airbag according to the different requirements of the pressure-holding components 21, improving the flexibility and adaptability of the equipment.

[0034] The pressure-holding telescopic assembly 4 includes a pressure-holding telescopic rod 41 fixedly mounted on a support frame, and the telescopic direction of the pressure-holding telescopic rod 41 is arranged vertically. A pressure sensor 44 is fixedly mounted on the telescopic end of the pressure-holding telescopic rod 41, and a connecting plate 45 is mounted on the bottom of the pressure sensor 44.

[0035] The pressure-holding telescopic assembly 4 also includes guide cylinders 42 fixed on the support frame. Each guide cylinder 42 is arranged sequentially around the pressure-holding telescopic rod 41, and the axial direction of each guide cylinder 42 is parallel to the telescopic direction of the pressure-holding telescopic rod 41. A guide rod 43 is coaxially slidably installed inside each guide cylinder 42, and the bottom of each guide rod 43 is fixed to the upper surface of the connecting plate 45. The top ends of each guide rod 43 are fixed to the same fixing ring 431, which is sleeved on the outside of the pressure-holding telescopic rod 41. This design not only simplifies the installation and adjustment of the guide structure but also enhances the overall integrity and rigidity of the guide system, making the pressure plate 3 more stable and reliable during movement.

[0036] A mounting plate 47 is provided on the lower side of the connecting plate 45, and the mounting plate 47 and the connecting plate 45 are connected to each other by a quick-connect coupling 46 commonly used at present.

[0037] A horizontally arranged mounting plate 47 has guide holes at each of its four corners. A T-shaped guide pin 471 is coaxially inserted into each guide hole, and the bottom end of the guide pin 471 is fixed to the upper surface of the pressure plate 3. A buffer spring 472 is coaxially sleeved on the guide pin 471 located between the pressure plate 3 and the mounting plate 47, and a correction gap is formed between the guide pin 471 and the guide hole to allow the guide pin 471 to tilt.

[0038] The pressure plate 3 and pressure-holding airbag 31 of this application can also be replaced with a corresponding hot press head module to hot press electrical components.

[0039] In use, the material tray 2, filled with the component to be pressed 21, is first placed in the limiting groove to fix the material tray 2 onto the base 1. Then, the drive cylinder, which serves as a pressure-holding telescopic rod 41, extends, causing the corresponding pressure plate 3 to extend vertically toward the component to be pressed 21. After the drive cylinder extends a set distance, the pressure-holding airbag 31 presses against the component to be pressed 21. At this point, the pressure-holding airbag 31 is inflated, and the reading of the pressure sensor 44 is monitored in real time. When the reading of the pressure sensor 44 reaches the set value, the pressure-holding time is set. After the pressure holding is completed, the drive cylinder resets, and the material tray 2 is removed, thus completing this round of pressure holding.

[0040] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
