Description

Technical Field

[0001] This utility model relates to the field of plastic parts processing technology, specifically to a rapid processing equipment for surface textures of plastic parts. Background Technology

[0002] During the processing of plastic parts, some plastic parts have corresponding textures on their outer walls to enhance their aesthetics.

[0003] A search revealed that patent application number 202322922680.X discloses a screen printing device for plastic parts, including a movable base, a controller connected to the side wall of the movable base, a worktable connected to the end face of the movable base, and a robotic arm connected to the end face of the movable base and located on one side of the worktable. The drive end of the robotic arm is connected to a quick-fixing structure via a connecting plate, and a screen printer is connected to the quick-fixing structure. This invention, by setting a quick-fixing structure in the screen printing device for plastic parts, utilizes the fixed connecting block in the quick-fixing structure to facilitate the disassembly of the screen printer through a transmission structure. This design allows for quick disassembly of the screen printer when it needs to be replaced during use, making it more convenient to use and solving the problem of inconvenient disassembly of the screen printer.

[0004] The aforementioned application documents achieve the corresponding printing of surface textures through the setting of printing filaments. However, the surface textures are formed by inward extrusion, which may cause the plastic parts on the outside of the textures to bulge out, affecting the quality of the entire plastic parts. How to perform scraping-type texture treatment on the surface of the plastic parts has become an urgent problem to be solved.

[0005] Therefore, we propose a rapid processing equipment for surface textures on plastic parts. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a rapid processing device for surface textures on plastic parts, which solves the problem that existing devices are unable to perform scraping-type texture processing on the surface of plastic parts according to requirements.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a rapid processing equipment for surface texture of plastic parts, including an electrical box base and a processing frame on its top side, a three-axis drive system is also provided on the top side of the electrical box base, a control panel is fixedly installed on the outer wall of the electrical box base, and a scraping component for processing texture on the surface of plastic parts inside the processing frame is assembled at the output end of the three-axis drive system.

[0008] The scraping assembly includes an assembly cylinder and a limiting post at its bottom end. A support cylinder is assembled on the bottom side of the limiting post, and a wedge tube is hinged to the bottom end of the support cylinder. The front end of the wedge tube is wedge-shaped, and the edge of the front end of the wedge tube is a sharpened edge.

[0009] As a preferred embodiment of this utility model, a support plate is fixedly installed at the top of the four corners of the processing frame, and an electric cylinder assembly is fixedly installed at the top of the support plate. A pressure strip is threaded onto the output end of the electric cylinder assembly, and the outer end of the pressure strip is pressed onto the top of the corner of the plastic part.

[0010] The electric cylinder assembly and the pressure strip at the bottom of its output shaft can press and limit the corner of the plastic part to be processed from the top side to ensure the processing effect of the subsequent texture.

[0011] In a preferred embodiment of this utility model, the scraping component is threadedly fitted onto the bottom end of the output shaft of the three-axis drive system via an assembly sleeve. The three-axis drive system includes an X-axis drive module, a Y-axis drive module, and a Z-axis drive module.

[0012] The assembly cylinder facilitates quick assembly and disassembly of the scraping components, while the specific structure of the three-axis drive system is as follows:

[0013] X-axis drive module

[0014] Guide rails: Generally composed of two parallel linear guide rails, fixed on the frame or base, providing precise linear motion guidance for the X-axis slider, ensuring smooth and accurate movement.

[0015] Slider: Mounted on the X-axis guide rail, it can slide along the guide rail in the X-axis direction. It is a key component that connects other parts and bears the load.

[0016] Lead screws or timing belts are crucial components for achieving precise transmission along the X-axis. Ball screws are driven by a motor to rotate, converting rotational motion into linear motion of a slider, and are characterized by high precision and high rigidity. Timing belt drives, on the other hand, transmit motor power to the slider through the cooperation of a timing belt and pulleys, offering advantages such as smooth transmission and lower cost.

[0017] Y-axis drive module

[0018] Crossbeam: It spans the two guide rails of the X-axis and is usually perpendicular to the X-axis guide rail. It is the support structure for the Y-axis movement and needs to have sufficient strength and rigidity to ensure the stability of the Y-axis movement.

[0019] Y-axis slider: Mounted on a guide rail on the crossbeam, it can slide along the crossbeam in the Y-axis direction, and is also used to connect and support the Z-axis module and load.

[0020] Drive mechanism: Similar to the X-axis, the Y-axis slider is driven by a motor through transmission components such as a lead screw or synchronous belt to move in the Y-axis direction.

[0021] Z-axis drive module

[0022] Column or bracket: Perpendicular to the plane containing the X and Y axes, fixed to the Y-axis slider, providing support and guidance for the movement of the Z-axis.

[0023] Z-axis slider: Mounted on the guide rail of the column or bracket, it can move up and down along the Z-axis and is used to mount end effectors, such as vacuum suction cups, robotic grippers, and cutting tools, to achieve different work tasks.

[0024] Transmission components: Typically, ball screws or chains are used to transmit the motor's power to the Z-axis slider, enabling precise lifting and lowering movements in the Z-axis direction.

[0025] Frame and support structure

[0026] The frame is the basic support component of the entire three-axis drive mechanism. It is usually made of high-strength steel or aluminum alloy materials, with sufficient strength and stability to withstand the weight of the X, Y, and Z axis modules and the load, and to ensure the relative positional accuracy between the axes.

[0027] Support base: Used to fix and support components such as guide rails and lead screws of each shaft, ensuring that they maintain a stable position and posture during operation, while also playing a role in shock absorption and reducing vibration transmission.

[0028] Transmission components

[0029] Ball screws are commonly used transmission components in three-axis drive mechanisms, consisting of a screw, a nut, and balls. When the motor drives the screw to rotate, the balls roll between the screw and the nut, converting the rotational motion into the linear motion of the nut. This design offers advantages such as high transmission efficiency, high precision, and low friction, enabling precise position control.

[0030] Synchronous belt / chain: Synchronous belt or chain drives transmit the motor's power to the sliders on each shaft through the meshing of pulleys or sprockets with the synchronous belt or chain. This transmission method has advantages such as smooth transmission, low noise, low cost, and simple maintenance, and is suitable for some applications where high precision is not required, but a large stroke and high speed are needed.

[0031] Couplings: Used to connect motor shafts and lead screws or other transmission components, serving to transmit torque and compensate for installation errors between the two shafts, ensuring effective power transmission and smooth movement.

[0032] Power source and control system

[0033] Servo motors / stepper motors are the power source for three-axis drive mechanisms. They control the motor's speed, direction, and position via pulse or analog signals from a controller, thus achieving precise control of each axis's motion. Servo motors offer high precision, fast response, and high torque output, making them suitable for high-precision, high-speed applications. Stepper motors, on the other hand, are simple to control and low-cost, making them suitable for applications with relatively lower precision and speed requirements.

[0034] The controller is the "brain" of the three-axis drive mechanism. It is responsible for receiving instructions from the host computer, such as motion trajectory, speed, and position information, and converting these instructions into control signals for the servo motors or stepper motors of each axis, coordinating the motion between the axes, and realizing complex motion control tasks.

[0035] Furthermore, this three-axis drive system is existing technology.

[0036] As a preferred embodiment of this utility model, the bottom side of the limiting post is provided with a through hole, and the side of the limiting post is also provided with an external locking hole that communicates with the through hole, and the top of the support cylinder is fixedly installed with a locking post inserted into the inside of the through hole.

[0037] The perforated design on the limiting post facilitates the flexible assembly of multiple scraping components, ensuring the synchronous quantity of texture opening and enabling rapid processing of multiple textures on the surface of plastic parts.

[0038] As a preferred embodiment of this utility model, an inner locking hole is provided on the outer wall of the locking post, the inner locking hole and the outer locking hole are positioned opposite each other, a side plate is provided on the outer side of the limiting post, a limiting card is fixedly installed on the side plate, and the end of the limiting card passes through the outer locking hole and is inserted into the inner side of the inner locking hole.

[0039] The limiting clip and side plate are both made of magnets. The setting of the limiting clip and side plate can simultaneously limit the position of the support cylinder from the outside, making it easy to quickly assemble and disassemble.

[0040] As a preferred embodiment of this utility model, the support cylinder is an inclined tube, and a wedge tube is rotatably fitted at the bottom end of the support cylinder, and the wedge tube and the support cylinder are assembled through an adjustment knob.

[0041] The adjustable knob facilitates the adjustment of the wedge tube's tilt angle, and its wedge-shaped bottom edge allows it to be driven by a three-axis drive system to quickly process the top surface of plastic parts.

[0042] This invention provides a rapid processing device for surface textures on plastic parts. It has the following beneficial effects:

[0043] 1. This rapid surface texture processing equipment for plastic parts, through the setting of the scraping component structure on the output shaft of the three-axis drive system, can adjust its quantity and tilt angle according to the needs, thereby enabling efficient scraping texture processing on the surface of plastic parts with bottom side limit according to the needs, ensuring the processing effect, and solving the problem that existing devices are difficult to perform scraping texture processing on the surface of plastic parts according to the needs.

[0044] 2. This rapid surface texture processing equipment for plastic parts, through the setting of electric cylinder assembly and pressure strip on the processing frame, can efficiently press and limit the placed plastic parts according to the requirements, ensuring the stability during subsequent scraping processing. At the same time, the shape setting makes it easy to adjust the position of its bottom end, ensuring the accuracy and effect of subsequent scraping processing. Attached Figure Description
