Description

Technical Field

[0001] The present invention relates to the technical field of fishing rod detection, in particular to a fishing rod bending detection device. Background Art

[0002] Fishing is becoming an increasingly popular outdoor activity, mainly using fishing rods to catch fish from the water. Fishing rods are divided into many types according to different materials, and can also be divided into one-piece rods and multi-section rods. Regardless of whether they are one-piece rods or multi-section rods, the shape of the fishing rod gradually becomes thinner and sharper from the handle to the rear end. For example, a multi-section rod is composed of several hollow sections, which are nested and stored when not in use, and are pulled out or plugged together in sequence when in use. The thinnest section of the fishing rod is called section 1; from the inside to the outside, that is, from thin to thick, it is section 2, section 3... and so on. Among them, section 1 is also called the tip section, and the thickest section with a handle is called the handle section or the hand handle section, also called section B.

[0003] In order to detect the quality of the fishing rod, it is necessary to detect the curvature at the top of the fishing rod. For example, for a multi-section rod, it is necessary to detect the curvature of the tip section. The existing detection method is manual detection. The detection personnel use both hands to hold the two ends of the tip section of the fishing rod respectively, and move them inwards so that the tip section bends inwards. If no breakage occurs during the entire bending process, the detection is passed. In addition, in order to further improve the inspection standard for the durability of the fishing rod, when the tip section bends inwards to reach the maximum test arc, the rear end of the tip section is rotated at the same time to detect the durability of the fishing rod after bending and rotating. If no breakage occurs during the entire bending and rotation process, the detection is passed. However, this manual detection method has the problems of low work efficiency, high labor intensity, and different detection standards for different people. Summary of the invention

The left bending detection mechanism 3 and the right bending detection mechanism 4 are arranged opposite to each other and are located at the rear end of the feeding mechanism 2. The left bending detection mechanism 3 and the right bending detection mechanism 4 are used for bending and rotation detection of fishing rods. The transport mechanism 5 is used for transporting and unloading operations of fishing rods. In addition, the automatic detection of the bending and rotation of fishing rods is realized, the efficiency of fishing rod detection is improved, the labor intensity of detection personnel is reduced, and the detection standard and quality of fishing rods are guaranteed.

[0036] The feeding mechanism 2 includes a loading rack 21 and a feeding base 27. The feeding base 27 is fixedly connected to the ground or the frame 1.

The loading rack 21 slides horizontally along the feeding slide rail 271 to adjust the initial position of the fishing rod loading.

[0037] A loading platform 211 is provided at the lower end of the loading rack 21, and a unloading platform 212 is provided at the upper end of the loading rack 21.

When sliding to the highest point, only one fishing rod is allowed to stay on the baffle 251, and the extra fishing rods are pushed out of the baffle 251. By adjusting the installation position of the screening plate 281 up and down, the width of the position where the fishing rods can stay on the baffle 251 can be adjusted, so that it is suitable for screening fishing rods of different diameters.

[0051] A method for detecting the bending of a fishing rod, the method adopts the above-mentioned device for detecting the bending of a fishing rod, and the specific steps are as follows:

[0052] S1. Initialize the fishing rod bending detection equipment, adjust the installation height of the screening plate on the screening material fixing plate according to the diameter of the fishing rod, set the initial position of the left detection claw and the distance of movement to the right detection claw according to the length of the fishing rod, set the inclination angle and inclination speed of the right detection claw according to the length of the fishing rod, and set the spin angle of the right detection claw to suit the screening, bending and rotation tests of the new fishing rod material;

[0053] Adjusting the installation height of the screen plate on the screen fixing plate according to the diameter of the fishing rod can meet the screening needs of fishing rods of different diameters; setting the initial position of the left detection air claw and the distance of movement toward the right detection air claw according to the length of the fishing rod, and then setting the bending angle of the fishing rod detection, which can be set to 0-180 degrees; setting the inclination angle and inclination speed of the right detection air claw according to the length of the fishing rod, and setting the spin angle of the right detection air claw, thereby setting the test standard for the bending and rotation detection of the fishing rod.

[0054] S2. The feeding mechanism starts to work, and the excess fishing rods on the baffle are screened off by the multi-stage screening assembly, leaving only one fishing rod on each baffle;

[0055] S3. When the sensor of the feeding mechanism detects that the fishing rod is in place, the lifting mechanism lifts up multiple fishing rods at the same time, and the material handling mechanism of the handling mechanism moves the fishing rod from the unloading platform of the feeding mechanism to the left bending detection mechanism and the right bending detection mechanism;

[0056] S4. The left detection air claw clamps the top of the fishing rod, and the right detection air claw clamps the top tail end of the fishing rod. The bending detection linear module drives the left detection air claw to move horizontally toward the right detection air claw. At the same time, the right detection air claw rotates and tilts under the drive of the swing motor or the swing rod. At this time, the two ends of the fishing rod move inward to achieve the bending of the fishing rod. The bending angle of the fishing rod is set according to the length of the fishing rod and the movement distance of the left detection air claw.

[0057] S5. When the bending of the fishing rod reaches the maximum bending degree, such as the maximum bending degree of 180 degrees, or during the bending process of the fishing rod, the rack linear module drives the right detection air claw to rotate, thereby realizing the detection of the bending and rotation of the fishing rod.

[0058] S6. If the fishing rod breaks during the above bending and rotating detection process, the torque sensor obtains the torque change signal, and then determines which fishing rod is broken; the unloading mechanism of the handling mechanism removes the broken fishing rod from the right detection claw and transports it to the waste box;

[0059] S7. After the left and right detection air grippers are reset, they are opened at the same time, and the normal fishing rods are dropped into the recycling box. At this time, the broken fishing rods left on the left detection air gripper also fall into the recycling box, and are subsequently removed manually.

[0060] S8. Repeat this cycle.

[0061] The number of fishing rods detected each time is related to the number of left detection air claws and right detection air claws set. To improve the efficiency of detection, the number of left detection air claws and right detection air claws can be increased.

[0062] The present invention solves the technical problems of low work efficiency, high labor intensity and differences in detection standards in manual detection, realizes separate bending detection or separate spin detection of fishing rods, and realizes the detection of bending and rotation of fishing rods.

[0063] The present invention uses a multi-stage screening component of a feeding mechanism to screen out excess fish rods on the baffle, so that only one fish rod is left on each baffle, thereby realizing automatic loading and sorting of fish rods; the fishing rods are transported from the unloading platform of the feeding mechanism to the left bending detection mechanism and the right bending detection mechanism through the picking mechanism of the transport mechanism, and the broken fish rods are removed from the right bending detection mechanism and transported to a waste box.

[0064] When the left bending detection mechanism works with the right bending detection mechanism, the left detection air claw clamps the top end of the fishing rod, and the right detection air claw clamps the top tail end of the fishing rod. The bending detection linear module drives the left detection air claw to move horizontally toward the right bending detection mechanism. At the same time, the right detection air claw rotates and tilts under the drive of the swing motor or the swing rod. At this time, the two ends of the fishing rod move inward to achieve the bending of the fishing rod; when the bending of the fishing rod reaches the maximum curvature, or during the bending process of the fishing rod, the rack linear module drives the right detection air claw to rotate, thereby realizing the detection of the bending and rotation of the fishing rod. If the fishing rod breaks during the above process, the torque change signal is obtained through the torque sensor to determine the position where the fishing rod breaks.

[0065] However, the above description is only a specific embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the scope of protection of the present invention should still fall within the scope covered by the claims of the present invention.
