Description

Technical Field

[0001] This utility model relates to the technical field of foam pressure holding equipment, and in particular to a multi-point foam pressure holding device. Background Technology

[0002] Foam is a porous elastomer material made of foamed plastic particles. It has the characteristics of being lightweight, highly elastic, sound and heat insulation, and shock absorption. It is widely used in furniture, packaging, automobiles, construction and other fields.

[0003] This technique involves applying pressure during the foam bonding process to ensure a thorough adhesion between the foam and the product surface. This technology is widely used in the production of electronic products and can improve the bonding accuracy and quality of foam.

[0004] However, current foam pressure-holding equipment generally can only hold pressure on single-point foam. When performing pressure-holding operations on multiple points of foam simultaneously, it cannot automatically adjust according to the foam bonding height at different points. This results in the foam not being effectively pressed down when the foam bonding height decreases, leading to significant differences in the foam bonding quality at different points.

[0005] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a multi-point foam pressure holding device to solve the above problems.

[0006] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solution of this utility model and facilitating the understanding of those skilled in the art. It should not be assumed that the above content is known to those skilled in the art simply because it has been described in the background section of this utility model. Utility Model Content

[0007] To overcome the shortcomings of the prior art, the present invention aims to disclose a multi-point foam pressure holding device, which solves the problems of uneven pressure, uneven product surface leading to unstable foam pressure holding quality, and inconvenient equipment maintenance and replacement in the prior art during the synchronous pressure holding process of multi-point foam.

[0008] This utility model discloses a multi-point foam pressure-holding device, including a base, a pressure-holding area and a loading / unloading area on the base, and a translation component on the base that can move back and forth between the pressure-holding area and the loading / unloading area, allowing products to be quickly transferred between different workstations and reducing production cycle time. The translation component has a pressure-holding base, the upper end of which has a positioning groove, and a detachable positioning fixture is installed in the positioning groove. The positioning fixture is detachable for easy replacement and maintenance, and can adapt to products of different specifications. A pressure-holding mechanism is provided above the pressure-holding area. The pressure-holding mechanism includes a fixed frame connected to the base, a downward pressure drive is provided on the fixed frame along the vertical direction, the output end of the downward pressure drive is connected to a horizontal pressure plate, and a floating pressure plate is provided below the horizontal pressure plate. At least two pressure heads are detachably provided at the lower end of the floating pressure plate, and at least two balance guide columns are provided on the upper surface of the floating pressure plate. The upper ends of the balance guide columns penetrate the horizontal pressure plate and are slidably connected to it. Balance springs are sleeved on the outer periphery of the balance guide columns, and the two ends of the balance springs abut against the horizontal pressure plate and the floating pressure plate, respectively. The design of the balance guide column and balance spring ensures that the floating pressure plate can automatically adjust during the pressure holding process, maintain the pressure of each pressure head evenly, and avoid uneven pressure caused by uneven product surface.

[0009] A preferred technical solution: A pressure sensor is installed between the output end of the downward pressure drive and the horizontal pressure plate. This sensor is used to monitor pressure changes in real time during the pressure holding process. Feedback from the pressure sensor allows for precise control of the output pressure of the downward pressure drive, ensuring the quality of pressure holding. At least two limiting guide rods are provided on the upper surface of the horizontal pressure plate, with the upper ends of the limiting guide rods passing through and slidably connected to the fixing frame.

[0010] Preferred technical solution: The top of the pressure head is equipped with a removable buffer pad made of elastic material. Using elastic material reduces impact on the product.

[0011] Preferred technical solution: The horizontal pressure plate and the floating pressure plate are square plates of equal size and arranged symmetrically. The output end of the downward pressure drive is coaxially connected to the geometric center of the horizontal pressure plate. There are four balance guide columns, and the four balance guide columns are symmetrically distributed around the center of the floating pressure plate.

[0012] Preferred technical solution: A cross coupling or universal joint is used for flexible connection between the balance guide column and the floating pressure plate. This allows the floating pressure plate a certain degree of freedom during the pressure holding process, accommodating minor unevenness on the product surface.

[0013] Preferred technical solution: A rectangular pressure block is installed at the lower end of the floating pressure plate, and a pressure head is connected to each of the four corners of the rectangular pressure block. The four pressure heads are equidistant from the center of the rectangular pressure block. This design ensures that the pressure heads are evenly distributed on the product surface and is suitable for pressure holding of large-sized products.

[0014] The preferred technical solution is as follows: Multiple positioning posts are provided within the positioning groove, and positioning holes that match the positioning posts are provided on the positioning fixture. This ensures the precise fixation of the positioning fixture on the pressure-holding base, preventing product displacement during the pressure-holding process.

[0015] Preferred technical solution: Limit photoelectric sensors corresponding to the translation components are installed in both the pressure holding area and the loading / unloading area to detect the position of the translation components and ensure that they move accurately to the designated workstation.

[0016] Preferred technical solution: The downward pressure drive is a servo electric cylinder, which can adjust the output pressure in real time according to the feedback of the pressure sensor to ensure the stability and consistency of the pressure holding process.

[0017] Preferred technical solution: A protective light curtain is installed between the pressure holding area and the loading / unloading area. The protective light curtain extends along the side of the fixed frame and covers the movement path between the two areas. This prevents operators from accidentally entering the dangerous area and ensures operational safety.

[0018] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0019] 1) The design of the balance guide column and balance spring ensures that the floating pressure plate can automatically adjust during the pressure holding process, maintain the pressure of each pressure head evenly, and avoid the problem of uneven pressure caused by uneven product surface;

[0022] 4) The cushioning pads are made of elastic material, which reduces the impact on the product and protects the product surface from damage;

[0023] 5) The design of floating pressure plates and rectangular pressure blocks, combined with four symmetrically distributed pressure heads, ensures that the pressure is evenly distributed on the product surface, making it particularly suitable for pressure holding of large-sized products;
