Description

Technical Field

[0001] This utility model belongs to the field of solid wood decorative mirror production technology, and in particular relates to a frame assembly tooling for irregularly shaped frame strips based on solid wood decorative mirrors. Background Technology

[0002] In the production process of solid wood decorative mirrors, robots are used to transfer the frame strips to an automatic framing machine, where they are positioned by tooling and then assembled. Currently, for aesthetic reasons, irregularly shaped mirrors are becoming more common, such as mirrors with a rounded top (arched), polygonal, or other irregular shapes. Due to the different curvatures and angles, traditional automatic framing machine tooling is designed for right-angle standard frames. Its clamping and positioning tooling is fixed and cannot be adjusted, making it unable to adapt to irregularly shaped frame strips with different curvatures and shapes, which has obvious limitations.

[0003] Currently, production can be carried out by manual assembly and by making special tooling. However, manual assembly has problems such as low efficiency, high cost and poor consistency. Special tooling can only be used for frames of specific shapes and sizes, has poor versatility, is too expensive and has a long preparation cycle. Summary of the Invention

[0004] The purpose of this utility model is to provide a frame assembly fixture for irregularly shaped frames based on solid wood decorative mirrors. Through the design of an air supply valve plate and multiple independently distributed frame-attaching mechanisms, the length of the frame-attaching mechanism can be adjusted according to the number of connecting rods. Furthermore, due to the cooperation between the piston rod and the piston chamber, it has a certain telescopic capacity, which can be arbitrarily adjusted according to the frame structure. Based on the air pressure, it ensures that the annular air bladders at the ends of all adsorption rods perfectly fit the mirror frame, greatly improving the applicability of the fixture and meeting the assembly and production needs of irregularly shaped frames.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a frame assembly tooling for irregularly shaped frames based on solid wood decorative mirrors, including a base, an air supply valve plate, several frame assembly cylinders, a manifold valve plate, and several frame attaching mechanisms. A plurality of the frame cylinders are horizontally fixed at the tail end of the top surface of the base, the air supply valve plate is slidably disposed on the upper surface of the base, and the ends of the telescopic rods of the plurality of frame cylinders are fixed to the back of the air supply valve plate. The air supply valve plate has a manifold at its inner rear end, and the front side of the air supply valve plate has a plurality of piston chambers that communicate with the manifold. The frame-attaching mechanism includes a piston rod, several connecting rods, and an adsorption rod; the number of connecting rods in the various frame-attaching mechanisms is different. The piston rod tail end is slidably disposed in the piston chamber, and the piston rod front end passes through the air supply valve plate and is provided with an L-shaped connection port. One end of the connection port extends to the front end axis of the piston rod, and the other end of the connection port extends to the peripheral side of the front end of the piston rod. Several of the connecting rods and adsorption rods are sequentially connected to the front end of the piston rod via pipe clamps; The adsorption rod has an end ring fixed at its front end, and an annular air bag is fixed outside the end ring. The inner hole of the end ring forms an adsorption port inside the annular air bag. The adsorption rod and the connecting rod are both hollow tube structures. The connecting port is connected to the adsorption port through several connecting rods and adsorption rods. The manifold valve plate is a long strip structure. The top of the gas supply valve plate is provided with several sliding edges. The manifold valve plate is slidably mounted on the top of several sliding edges.

The front ends of the piston rods of several of the frame-attaching mechanisms are fixed to the bottom edge of the protective plate. The manifold valve plate is provided with a flow-dividing cavity. Several pipes connected to the flow-dividing cavity are linearly provided on the front side of the manifold valve plate. Several pipes are respectively connected to the connection ports of several frame-attaching mechanisms. The protective plate is located between the pipes and the air supply valve plate.

[0006] Furthermore, both ends of the piston chamber are provided with constricted openings, the piston rod passes through the constricted opening at the front end of the piston chamber and is sealed between them, and the piston rod is provided with a piston head that is slidably connected to the piston chamber at the end near the manifold.

[0007] Furthermore, when the piston head contacts the constricted opening at the tail end of the piston chamber, the connection port, the connection between the guard plate and the piston rod are all located outside the air supply valve plate.

[0008] Furthermore, an L-shaped plate is fixed to the front top of the base. The L-shaped plate has several guide holes. Several connecting rods of the frame-attaching mechanism near the air supply valve plate pass through the several guide holes. A limiting platform is provided in the guide hole. The peripheral side of the connecting rod has a flat opening that slides with the limiting platform.

[0009] Furthermore, the tail end of the adsorption rod, both ends of the connecting rod, and the front end of the piston rod are all provided with annular grooves, and both ends of the pipe clamp are provided with embedded rings that cooperate with the annular grooves.

The length of these mechanisms can be adjusted based on the number of connecting rods. Furthermore, the piston rod and piston chamber provide the mechanism with a certain degree of telescopic capability, allowing for arbitrary adjustment according to the frame structure. Air pressure ensures that the annular airbags at the ends of all adsorption rods perfectly fit the frame. These annular airbags, serving as contact surfaces, accommodate frame strips with varying curvatures, significantly expanding the tooling's applicability, enabling the assembly and production of irregularly shaped frames, and enhancing the equipment's versatility.

[0014] This invention designs a passage at the axis of the connecting rod, piston rod, and adsorption rod of the frame-attaching mechanism, which can create negative pressure at the position of the annular air bladder at the end of the adsorption rod, enabling the entire frame to be adsorbed. This achieves the fixation of the tooling on the frame position, ensuring the stability and accuracy of the subsequent frame assembly process, and guaranteeing the efficiency and precision of the frame assembly.

[0027] The working principle of this utility model is as follows: A robot drives the adsorption head to move the irregular frame strip to the outer side of the front end of the adsorption rod 503 of several frame-attaching mechanisms 5. Air is supplied to the manifold 201 through the air supply interface. The gas is evenly distributed into the piston chamber 202, pushing the frame-attaching mechanism 5 to move towards the irregular frame strip. When the annular airbag 507 contacts the irregular frame strip and deforms (detected by the pressure of the pipeline connected to the air supply interface), the air supply is stopped, and the gas in the diversion chamber 402 is extracted through the air extraction interface. The air is extracted through the pipe 403, the connection port 504, the connecting rod 502 and the adsorption rod 503, forming a negative pressure at the annular airbag 507, which adsorbs and fixes the irregular frame. At this time, the robot's adsorption head is removed. In the subsequent frame assembly, the frame assembly cylinder 3 pushes the air supply valve plate 2, the frame-attaching mechanism 5 and the adsorbed irregular frame to move to realize the subsequent frame assembly process.
