Description

TECHNICAL FIELD

[0001] The present application relates to the field of grid production, in particular to a grid forming assembly for preventing filament shedding at corners. BACKGROUND

[0002] In the field of industrial production, composite grid products are widely used in many fields due to their unique advantages. With the continuous progress of science and technology, their production technology is also developing. The existing composite grid production equipment mainly realizes the optimization of the production process through automation technology. For example, the fully automatic production line of molded grid can realize the automation of all processes in the production cycle of molded grid, shorten the process interval, improve the product production efficiency, and is conducive to the large-scale production of molded grid. The production line adopts new weaving devices and injection molding devices, the fiber weaving is more reasonable, the repetition rate is reduced, the resin injection is accurately quantified, and the resource utilization rate and the overall quality of the molded grid product are improved.

[0003] However, although these automation technologies have improved production efficiency and product quality to some extent, some problems have been exposed in actual application. In the production process, the laying and compaction of fibers are key steps, but the automation degree and precision of existing equipment in these two links still need to be improved. Especially when the fiber is laid to the corner position of the outer edge, the change of the fiber direction is easy to cause the occurrence of filament shedding. This filament shedding not only affects the appearance and dimensional accuracy of the product, but also may cause the mechanical properties of the product to decrease, affecting its stability and reliability in actual application. In addition, in the injection process, the fluidity and filling property of the resin are difficult to accurately control, bubbles and defects are easy to appear, further reducing the mechanical properties and durability of the product. The existence of these problems not only affects the quality of the product, but also limits the further improvement of the production efficiency.

[0004] Therefore, it is of great significance and value to develop new technologies. CONTENT OF THE INVENTION

[0005] The purpose of the present application is to at least overcome one of the deficiencies of the prior art, and to provide a grid forming assembly for preventing filament shedding at corners.

[0006] To achieve the above-mentioned purpose, the present application discloses a grid forming assembly for preventing filament shedding at corners, which structure comprises a base frame provided with transversely and longitudinally staggered forming grooves, and a filament shedding prevention execution mechanism distributed in the corner area of the base frame.

[0007] The filament shedding prevention execution mechanism is composed of a main filament pressing device and a secondary filament pressing device. The main filament pressing device is arranged on the first corner side wall of the base frame, and the secondary filament pressing device is arranged on the adjacent second corner side wall. The two groups of devices realize the pressing of the fiber material during the filament laying operation through composite motion control.

[0008] The main pressing device is composed of a fixed base, a horizontal rotary driving mechanism, a vertical telescopic executing mechanism and a first pressing plate; the fixed base is rigidly connected with the first side wall of the base frame through fasteners, and a rotary power source with a horizontally arranged output shaft is arranged on the top of the fixed base; a mounting bracket is connected with the output end of the rotary driving source, and a pneumatic linear actuator is arranged at the end of the mounting bracket to form a vertical telescopic driving unit, and a first pressing plate with a straight-angled bent structure is arranged at the end of the actuator piston rod.

[0009] The secondary pressing device adopts an integrated driving module, and the structure comprises an executing mechanism with double degrees of freedom output; the executing mechanism is fixed to the second side wall of the base frame, and the output end thereof can realize composite motion of horizontal axial rotation and vertical axial displacement; a second pressing plate is mounted on the motion end of the executing mechanism.

[0010] Further, the grid forming assembly is integrated with a heat conduction functional unit, which is communicated with an external heat source device through an internal fluid circulation channel to form a controllable heating system for the forming area.

[0011] Further, the fluid circulation channel is arranged along a continuous circuitous path inside the forming base, and the channel cross-sectional shape is matched with the thermal expansion characteristics, so that the heat transfer of the fluid medium forms a uniform temperature field in the forming groove area.

[0012] Further, the bottom of the grid forming assembly is provided with an ejection executing mechanism, and the mechanism comprises a power driving unit, a linkage guiding assembly and a forming surface contact unit, wherein the contact unit has a profile structure matched with the geometric features of the grid bottom surface, and the product is ejected through a multi-directional synchronous advancing mechanism when the ejection action is performed, so as to facilitate the discharge.

[0013] During the operation process, the main pressing device first starts the horizontal rotary driving mechanism to rotate the pressing member to the upper side of the fiber laying path, and then the vertical telescopic executing mechanism pushes the first pressing plate downward to complete the initial fixation of the fiber material in the forming groove of the first side wall. When the fiber laying mechanism travels to the corner area, the executing mechanism of the secondary pressing device synchronously performs the horizontal rotation and vertical pressing actions, so that the second pressing plate forms dynamic pressing on the fiber material of the second side wall in a progressive contact manner. The two groups of pressing devices realize smooth transition of the pressing torque through time sequence control, form continuous pressure distribution in the corner area, and effectively eliminate the fiber material from the corner.

[0014] Further, the anti-unraveling executing mechanism has four, and one is arranged at each corner position of the base frame.

[0015] The technical scheme solves the problem of fiber material slippage in the corner area of the grid forming through the cooperation of the multidirectional cooperative pressing mechanism and the dynamic constraint system. Based on the spatial geometric constraint relationship and the motion trajectory coupling mechanism of the primary and secondary pressing units, a continuous composite pressure field is formed in the fiber laying path mutation area. Through the dynamic balance of the vertical primary constraint force and the tangential secondary constraint force, the local stress concentration between the fiber layers is eliminated. At the same time, the real-time following adjustment capability of the pressing mechanism ensures the stability of the tension state of the fiber bundle in the corner transition stage. Combined with the pressure gradient loading strategy of the time sequence control, the smooth stress transmission of the fiber material from the straight section to the corner section is realized, and the fiber slippage or slippage phenomenon caused by the path mutation is fundamentally avoided, thereby ensuring the structural integrity and forming precision of the grid product.

[0016] The above-listed beneficial effects are not exhaustive of all advantages. Other potential beneficial effects and detailed technical implementation manners will be further disclosed in the embodiments or other description parts of the present application. BRIEF DESCRIPTION OF DRAWINGS

[0026] Reference is made to the accompanying drawings throughout the Figs. 1 to 4 In this embodiment, a corner anti-drawing grid forming assembly is provided, which effectively solves the problem of fiber material drawing caused by path change in the corner area through structural design and synergistic mechanism. The following will be described in detail from the overall structure composition, the connection and matching relationship of each part, the specific working principle and why it can effectively prevent drawing, etc.

[0027] In this embodiment, the grid forming assembly is mainly composed of a base frame 1, an anti-drawing execution mechanism 2, a heat conduction functional unit (not shown in the figure) and an ejection execution mechanism (not shown in the figure).

[0028] The base frame 1, as the support structure of the whole assembly, is made of high-strength metal material, for example: steel, and is internally provided with transversely and longitudinally staggered forming grooves, the geometric shape of which matches the design requirements of the grid product, ensuring that the fiber material can be closely attached during the forming process.

[0029] The anti-drawing execution mechanism 2 is composed of a main pressure device 201 and a secondary pressure device 202, which are arranged on the first corner side and the adjacent second corner side of the base frame 1, respectively. The main pressure device 201 is rigidly connected with the base frame 1 through a fixed base, which is made of high-strength steel material to ensure that the device will not displace or deform during the working process.

[0030] More specifically, the top of the main pressing device 201 is equipped with a servo motor 2011, the output shaft of which is arranged horizontally as a rotary power source. The output end of the rotary power source is connected with a mounting bracket 2012, the end of which is equipped with a pneumatic linear actuator 2013, constituting a vertical telescopic driving unit. The piston rod of the pneumatic actuator 2013 is equipped with a first pressing plate 2014 with a straight-angled bent structure in cross section, which is matched in shape and size with the geometric features of the forming groove, so as to ensure that the fiber material is constrained in the forming groove during pressing.

[0031] In the present embodiment, the secondary pressing device 202 adopts an integrated driving module 2021, which is a double-degree-of-freedom actuator capable of realizing combined motion of horizontal axial rotation and vertical axial displacement. The actuator is fixed to the second side wall of the base frame 1, and the moving end of the actuator is connected with a second pressing plate 2022. The second pressing plate 2022 is matched in shape and size with the first pressing plate, and can form continuous pressing constraints in the corner area.

[0032] In some embodiments, a heat conduction functional unit is integrated inside the base frame 1 and communicates with an external heat source device through a fluid circulation channel, constituting a controllable heating system for the forming area. The fluid circulation channel is arranged in a continuous circuitous path inside the base frame 1, and the channel cross section shape is matched with the thermal expansion characteristics, so that the forming groove area can form a uniform temperature field through heat transfer of the fluid medium. The specific design of the fluid circulation system and the temperature control algorithm belong to the prior art, which will not be described in detail here.

[0033] In some embodiments, the ejection actuator is arranged at the bottom of the assembly, including a power driving unit, a linkage guide assembly and a forming surface contact unit. The power driving unit adopts a high-precision stepping motor, which can drive the contact unit to complete the ejection action through a multi-directional synchronous propulsion mechanism. The installation and control mode of the motor belong to the known technology of those skilled in the art. The linkage guide assembly ensures the stability and precision of the ejection action, and the specific design of the guide mechanism belongs to the prior art. The forming surface contact unit has a profile structure matched with the geometric features of the grid bottom surface, which can closely fit the surface of the product during ejection, avoiding damage to the product caused by uneven contact.

[0034] In actual operation, the main pressing device 301 first rotates horizontally, so that the first pressing plate 2014 is rotated to the upper side of the fiber laying path. Then, the first pressing plate 2014 is lowered by vertical extension, so that the initial fixing of the fiber material in the first side wall forming groove is completed. When the fiber laying mechanism reaches the corner area, the actuator of the secondary pressing device synchronously performs horizontal rotation and vertical pressing actions, so that the second pressing plate dynamically presses the fiber material of the second side wall in a progressive contact manner. The smooth transition of the pressing torque is realized by the timing control of the two groups of pressing devices, so that a continuous pressure distribution is formed in the corner area, and the fiber material is effectively prevented from being separated from the forming groove due to the change of the path in the corner area.

[0035] It can be understood that the fiber material is prone to be separated in the corner area, mainly because in the traditional grid forming process, the pressing force on the fiber material in the corner area is uneven, so that when the path of the fiber material changes in the corner area, the fiber material is easily separated from the forming groove due to the centrifugal force and inertial force. In the embodiment, the main pressing device 201 and the secondary pressing device 202 work together to ensure that a continuous and uniform pressure distribution is formed in the corner area, so that the separation of the fiber material is effectively prevented. The main pressing device 201 realizes the initial fixing of the fiber material by horizontal rotation and vertical extension actions, and the secondary pressing device 202 realizes the dynamic pressing of the fiber material by two degrees of freedom movement. The smooth transition of the pressing torque is ensured by the precise timing control of the two groups of devices, so that the fiber material is prevented from being separated from the forming groove due to the sudden change of the pressure.

[0036] Through the above design, the grid forming assembly of the embodiment can significantly improve the production efficiency while ensuring the forming quality. In particular, in the corner area, the main pressing device and the secondary pressing device work together to effectively avoid the separation of the fiber material, which is suitable for the manufacturing scene of high-strength grid products.

[0037] Although the exemplary embodiments of the present disclosure have been described, it should be understood that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included in the protection scope of the present disclosure defined by the claims. The present disclosure is defined by the appended claims, and the equivalents of these claims are also included.
