Description

Technical Field

[0001] This utility model relates to the technical field of flexible coil shell processing equipment, specifically a flexible coil shell processing equipment. Background Technology

[0002] Flexible coil housings, designed to accommodate the flexible installation requirements of coils, are commonly made of flexible materials such as silicone and thermoplastic elastomers. They are widely used in consumer electronics, new energy vehicles, and smart wearables. Flexible coil housing grinding equipment is one of the core pieces of equipment in the post-processing of flexible coil housings. It is mainly used to remove burrs, gate residues, scratches, and unevenness from the surface of the formed housing, improving its surface smoothness and feel. Furthermore, to accommodate the easily deformable nature of flexible materials, existing grinding equipment is generally equipped with an elastic holding structure. This structure uses cylinders or springs to control the contact pressure between the grinding head and the workpiece, preventing over-grinding that could damage the housing and meeting the basic processing accuracy and production capacity requirements of flexible coil housings.

[0003] In the current processing of flexible coil shells, the positioning and clamping structure of grinding equipment is not adaptable enough. Most equipment uses fixed fixtures for positioning. When processing flexible shells of different sizes and curvatures, the fixtures need to be replaced and recalibrated, which takes a long time. In addition, the contact area between the fixture and the shell is prone to indentation due to rigid clamping, which leads to an increase in the appearance defect rate of the finished product. Utility Model Content

[0004] The purpose of this utility model is to provide a flexible coil shell processing equipment to solve the problem of insufficient adaptability of the positioning and clamping structure of the grinding equipment mentioned in the background art. Most equipment uses fixed clamps for positioning. When processing flexible shells of different sizes and curvatures, it is necessary to change the clamps and recalibrate, which takes a long time. In addition, the contact part between the clamp and the shell is prone to indentation due to rigid clamping, which leads to an increase in the appearance defect rate of the finished product.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a flexible coil shell processing equipment, including a frame, which is the overall load-bearing structure of the device, an electric drive slide rail is installed on the upper end face of the frame, and a sliding platform is slidably connected on the electric drive slide rail, the sliding platform being used to support the processing of flexible coil shells; The upper end of the frame is symmetrically provided with columns, and the top of the columns is equipped with a transverse lead screw slide. The slide of the transverse lead screw slide is connected to the longitudinal lead screw slide, and the slide of the longitudinal lead screw slide is connected to the electric grinder through the frame. The electric grinder is located directly above the buffer plate. Auxiliary support feet are installed on both sides of the bottom of the sliding platform, and infrared position detectors are installed on both sides of the sliding platform. Two clamping platforms are provided on the upper surface of the sliding platform, and buffer plates are embedded inside the clamping platforms. Two guide rails are symmetrically arranged in a circle on the upper surface of the buffer plate, and a sliding table is slidably connected inside the guide rails. A positioning chuck is installed at the output end of the sliding table.

[0006] Using the above technical solution, the frame and column form a stable load-bearing foundation. The horizontal and vertical lead screw slides enable precise positioning of the grinder. The guide rail and sliding table work together to make the positioning chuck adaptable to workpieces of various sizes, eliminating the need to change fixtures. The dual clamping platform improves processing efficiency.

[0007] Preferably, the frame and column form a U-shaped structure, and the top of the frame is provided with a mounting groove adapted to the electric drive slide rail, and the electric drive slide rail is a double-rail structure driven by a servo motor.

[0008] By adopting the above technical solution, the U-shaped structure enhances the stability of the frame and column support, ensuring smooth operation of the grinding mechanism, and the dual-rail servo electric drive slide rail improves the movement accuracy of the sliding platform, avoiding processing deviations caused by platform shaking.

[0009] Preferably, the transverse lead screw slide, the longitudinal lead screw slide, and the electric grinder together form a grinding mechanism, and the grinding mechanism is located directly above the clamping platform.

[0010] By adopting the above technical solution, the integrated grinding mechanism can achieve two-dimensional adjustment in both the horizontal and vertical directions, and ensures that the grinding position is accurately aligned with the clamping platform, thereby improving the grinding accuracy of different areas and batch consistency.

[0011] Preferably, the upper surface of the clamping platform is provided with inwardly inclined slopes on both sides, and the clamping platform is flush with the surface of the buffer plate, and the clamping platform has a groove adapted to the guide rail.

[0012] Using the above technical solution, the inner inclined surface achieves initial guiding and limiting of the workpiece, reducing placement deviation. It is flush with the buffer plate to ensure stable support of the workpiece. The matching groove improves the installation accuracy of the guide rail and reduces the offset of the sliding table.

[0013] Preferably, a miniature cylinder is mounted on the surface of the sliding stage, and a miniature signal transmitter is mounted on the surface of the miniature cylinder, and the miniature cylinder and the miniature signal transmitter are electrically connected.

[0014] By adopting the above technical solution, the micro cylinder can controllably adjust the clamping force, and the micro signal transmitter can provide real-time feedback on the clamping status, triggering the subsequent grinding process and improving the degree of automation and clamping reliability.

[0015] Preferably, the positioning clamp is configured as a C-shaped structure, and the positioning clamp is made of silicone material, and negative pressure adsorption plates are symmetrically installed inside the positioning clamp.

[0016] Using the above technical solution, the silicone material and C-shaped structure achieve flexible bonding, avoiding rigid indentations. The negative pressure adsorption plate forms double fixation, which not only prevents workpiece displacement but also protects the appearance of the shell and reduces the defect rate.

[0017] Preferably, the surface of the negative pressure adsorption plate is provided with holes, and the negative pressure adsorption plate is connected to the micro cylinder through a connecting air pipe.

[0018] Using the above technical solution, the holes in the adsorption plate allow negative pressure to be applied evenly to the workpiece, enhancing the fixing effect. It can also be connected to a micro cylinder to achieve synchronous control of negative pressure, improving the stability of clamping and adsorption.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the flexible coil shell processing equipment: 1. This equipment utilizes the sliding cooperation between the guide rails arranged symmetrically in a circular pattern on the upper part of the buffer plate and the sliding table, combined with the telescopic structure of the positioning chuck driven by a micro cylinder. It can move flexibly along the guide rails via the sliding table without changing the fixture, adapting to the clamping requirements of flexible coil shells of different sizes. The C-shaped positioning chuck can achieve a close fit through the fine adjustment of the cylinder stroke. With the structure of the double clamping platform on the sliding platform, when changing models, it is only necessary to switch the workstation and fine-tune the position of the sliding table by the electric drive guide rail, without recalibrating the fixture, thus improving the adaptability and efficiency of multi-specification processing. 2. The positioning chuck is made of silicone and designed with a C-shaped structure. Its flexible material can flexibly fit the surface of the flexible coil shell, avoiding the hard contact and squeezing of traditional rigid clamps. At the same time, the negative pressure adsorption plates symmetrically installed inside the positioning chuck are connected to the micro cylinder through the connecting air pipe, forming a double fixation of flexible clamping and negative pressure adsorption. This ensures clamping stability and disperses clamping force. In addition, the buffer plate embedded in the clamping platform absorbs clamping and grinding vibration, effectively preventing the formation of indentations on the shell surface. 3. The infrared position detectors on both sides of the sliding platform can detect the platform's movement position in real time. Combined with the dual-rail servo-driven electric slide rail, it ensures that the sliding platform moves the workpiece precisely to the grinding position. The linkage structure of the horizontal lead screw slide and the vertical lead screw slide at the top of the column can drive the electric grinder to achieve two-dimensional precise positioning. The grinding mechanism is always located directly above the clamping platform. Combined with the stable support of the U-shaped frame and auxiliary legs, it avoids grinding deviation caused by equipment shaking during processing. Attached Figure Description
