Description

Technical Field

[0001] The invention belongs to the field of fishing gear processing equipment, and particularly relates to a full-automatic water mill. Background Art

[0002] A carbon fiber fishing rod, also known as a carbon fishing rod, is a type of fishing rod. Compared to ordinary fiberglass and traditional fishing rods, it boasts superior toughness and light weight. Made from high-tech carbon fiber composite prepreg fabric, this rod is currently manufactured using a non-woven carbon fiber longitudinal, or warp, unidirectional fabric tube, which is then impregnated with resin and cured. During the production process, the finished product is wrapped with a layer of transparent plastic tape. The tension of the plastic tape secures the carbon fabric, but removing the tape leaves marks on the rod surface, which can cause dimensional deviations at the joints between individual rod sections, preventing smooth and secure connection between sections. This requires polishing the rod surface. Furthermore, to enhance the rod's aesthetics, the rod body requires painting, which is best achieved with polished and spray-coated sections. Existing water mills typically use a motor to drive the grinding wheel. A rod is manually placed between the grinding wheel and the extrusion wheel. The extrusion wheel is manually pushed toward the grinding wheel so that both the extrusion wheel and the grinding wheel come into contact with the rod. The rod is then manually pushed to move the grinding wheel. This results in low grinding efficiency, high labor intensity, low grinding accuracy, and large grinding errors, which affect subsequent processes. Summary of the Invention

DETAILED DESCRIPTION

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0037] It should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. A person of ordinary skill in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0038] like Figure 1 and Figure 2 As shown, the fully automatic water mill of the present invention includes a frame 1 and a loading device 2, a handling robot 3, a grinding device 7, a clamping and rotating device 4, a rod rotation and positioning device 6 and a discharge device 5 arranged on the frame 1. The handling robot 3 transfers the rod body on the loading device 2 to the rod rotation and positioning device 6, the clamping and rotating device 4 clamps one end of the rod body on the rod rotation and positioning device 6 to drive the clamping rod body to rotate, the grinding device 7 is arranged on one side of the clamping and rotating device 4, and grinds the rod body clamped by the clamping and rotating device 4, and the discharge device 5 removes the ground rod body from the rod rotation and positioning device 6.

[0039] See also Figure 2 、 Figure 3 、 Figure 4 and Figure 10The loading device 2 includes a silo platform 201, a loading platform 202, a feeding cylinder 203, a push plate 204, and a positioning rod 205. The lower end of the push plate 204 is connected to the feeding cylinder 203, and the upper end pushes the upper rod body of the silo platform 201 to the loading platform 202. A positioning rod 205 is provided above the loading platform 202. The positioning rod 205 is installed on the positioning rod fixed shaft 206. The positioning rod fixed shaft 206 is supported by a seat bearing 211 provided on the silo side plate 210. The positioning rod fixed shaft 206 is connected to the positioning cylinder 209 through a first connecting rod 207 and a second connecting rod 208. The loading device 2 includes a loading hopper sliding plate 212 and a rod alignment drive mechanism 213. A loading limit plate 214 and a sensor 215 are located on one side of the loading hopper sliding plate 212. The rod alignment drive mechanism 213 includes an alignment motor 2131 and a loading limit wheel 2132. The alignment motor 2131 drives the loading limit wheel 2132 to rotate, moving the rod toward the loading limit plate 214. The hopper platform 201 is connected to the rod conveyor belt, or the rods to be processed are placed manually on the hopper platform 201. The hopper platform 201 is tilted, and the rods on the hopper platform 201 move toward the push plate 204. Multiple push plates 204 are fixed to the push plate 204 mounting plate. When the piston rod of the feed cylinder 203 extends, the push plates 204 move upward, pushing the rods on them onto the loading platform 202. The stroke of the positioning cylinder 209 can be adjusted according to the thickness of the rod. The positioning cylinder 209 acts on the positioning rod fixed shaft 206 through the first connecting rod 207 and the second connecting rod to swing it, thereby causing the positioning rod 205 to limit or release the limit of the rod on the loading platform 202. When the limit is released, the rod slides from the loading platform 202 to the loading bin sliding plate 212. When the end of the rod on the loading bin sliding plate 212 does not contact the loading limit plate 214, the rod alignment drive mechanism 213 works, and the alignment motor 2131 drives the loading limit wheel 2132 to rotate. The loading limit wheel 2132 moves the rod toward the loading limit plate 214 until the end of the rod reaches the loading limit plate 214. The sensor 215 senses that the rod is in place, and the alignment drive mechanism stops working. The setting of the feeding limit plate 214 and the alignment drive mechanism ensures the position accuracy of the end of the rod body to be polished, avoids polishing errors caused by rod body position errors during the polishing process, and improves polishing accuracy.

[0040] The structure of handling robot 3 is shown in Figure 5The handling robot 3 transfers the rod on the upper hopper sliding plate 212 to the rod rotation positioning device 6 to facilitate the gripping of the rod by the gripping rotation device 4.
