Description

Technical Field

[0001] The utility model belongs to the technical field of fishing rod strength detection equipment, in particular to a fishing rod tip strength detection machine. Background Art

[0002] Fishing rods typically feature a multi-section telescopic structure. The tip, also known as the "point," "rod tip," or "rod tip," is the thinnest and most sensitive part of the rod and is typically made of lightweight, high-strength materials such as carbon fiber or fiberglass. The rod tip is a delicate design, ensuring sufficient strength to withstand the pull of the fish while maintaining sufficient sensitivity to signal a bite. Due to its small diameter, the tip is most susceptible to breakage during fishing, and its quality directly impacts the overall quality of the rod. To ensure rod quality, tip strength testing is performed during the manufacturing process. Due to the lack of automated testing equipment, tip strength testing is often done manually. The operator holds the butt end of the rod with one hand and the end with the other, bending it downward. A tip is considered acceptable if it does not break. Manual testing is labor-intensive, inefficient, and incomplete, requiring only spot checks. Spot checks can lead to missed inspections, and unqualified tips can be passed on to subsequent stages, adding unnecessary costs. Therefore, it is urgent to develop an automated testing device to replace manual testing of the rod tip strength. Utility Model Content

DETAILED DESCRIPTION

[0028] 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.

[0029] 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.

[0030] like Figure 1 and Figure 2As shown, the present invention fishing rod tip strength testing machine includes a material moving device 3 and a testing device 4, both of which are arranged on a frame 1, the material moving device 3 receives and conveys the tip of the rod to be tested to the testing device 4, the testing device 4 includes an A-end clamping mechanism 41 for clamping the thick end of the rod tip and a B-end clamping mechanism 43 for clamping the thin end of the rod tip, the A-end clamping mechanism 41 is connected to an angle adjustment mechanism 42, the B-end clamping mechanism 43 is connected to a Z-direction shifting mechanism 44 for adjusting the up and down positions, and the Z-direction shifting mechanism 44 is connected to an X-direction shifting mechanism 45 for adjusting the left and right positions. After the A-end clamping mechanism 41 and the B-end clamping mechanism 43 clamp the two ends of the rod tip, the angle adjustment mechanism 42 adjusts the A-end clamping mechanism 41 to make the rod tip tilt up a certain angle, and the B-end clamping mechanism 43 moves the rod tip along the Z and X directions to bend it, and the rod tip is judged to be qualified if it does not break at the preset bending position, otherwise it is unqualified.

[0031] The fishing rod tip strength testing machine also includes a feeding device 2 for feeding the rod tip to the material transfer device 3. Figure 3 and Figure 4 The loading device 2 includes a silo platform 201, a loading platform 202, a feeding cylinder 203, and a top plate 204. The lower end of the top plate 204 is connected to the feeding cylinder 203, and the upper end pushes the rod body on the silo platform 201 to the loading platform 202. A blocking claw is provided above the loading platform 202 to limit the rod body. The blocking claw is installed on the swing arm beam. The swing arm beam is connected to the swing arm cylinder 211 through the first connecting plate 209 and the second connecting plate 210. The first connecting plate 209 and the second connecting plate 210 are hinged. The two ends of the swing arm beam are supported by the seat bearing 213 arranged on the silo side plate 212. The swing arm crossbeam includes a first swing arm crossbeam 205 and a second swing arm crossbeam 206. The first swing arm crossbeam 205 is equipped with several first material blocking claws 207. These first material blocking claws 207 are flat and inclined, with the inclined surface at the top of the ejector plate 204 oriented in the same direction as the first material blocking claws 207. The second swing arm crossbeam 206 is equipped with several second L-shaped material blocking claws 208. The silo platform 201 is connected to the rod conveyor belt, or the rods to be loaded are placed directly on the silo platform 201. The silo platform 201 is tilted, and the rods on the silo platform 201 move toward the ejector plates 204. The ejector plates 204 are fixed to the ejector plate mounting plate 214. When the piston rod of the feed cylinder 203 extends, the ejector plates 204 move upward, pushing the rods onto the loading platform 202. The loading platform 202 is set at an angle, and the first blocking claw 207 pushes the top plate 204 to the rod tip of the loading platform 202. The first swing arm beam 205 rotates the first blocking claw 207 to release the limit on the rod tip, and the rod tip slides along the inclined surface of the loading platform 202 toward the second blocking claw 208. The second blocking claw 208 limits the rod tip. When the second swing arm beam 206 rotates and the second blocking claw 208 releases the limit on the rod tip, the rod tip slides along the inclined loading platform 202 to the material moving device 3.

[0032] In this embodiment, see Figure 5 and Figure 7 The material moving device 3 includes a material receiving block 31 and a material receiving block mounting plate 32. The material receiving block mounting plate 32 is connected to a Y-axis shifting mechanism for adjusting the front and rear positions. The material receiving block 31 includes a first inclined surface 311 and a second inclined surface 313. A receiving groove 312 is formed between the first inclined surface 311 and the second inclined surface 313. The rod tip slides from the first inclined surface 311 into the receiving groove 312. The receiving groove 312 limits the position of the rod tip to ensure that the A-end clamping mechanism 41 and the B-end clamping mechanism 43 accurately clamp the rod tip. A material receiving stopper 8 is provided on the frame 1 on the side of the second inclined surface 313. The material receiving stopper 8 limits the position of the rod tip that slides off the feeding device 2, ensuring that the rod tip slides into the receiving groove 312 between the first inclined surface 311 and the second inclined surface 313. The Y-direction shifting mechanism can adopt a material shifting cylinder 33, which is connected to the material receiving block mounting plate 32, driving the material receiving block 31 to move back and forth, and transporting the rod tip connected to the feeding device 2 to the detection device 4.

[0033] See also Figure 6 A positioning push plate 6 is provided on one side of the A-end clamping mechanism 41 at the position corresponding to the material receiving position of the material moving device 3, and the positioning push plate 6 is connected to the positioning cylinder 7. The positioning cylinder 7 pushes the positioning push plate 6 to move the rod tip on the material receiving block 31, preparing for the A-end clamping mechanism 41 to clamp the rod tip.

[0034] In this embodiment, see Figure 5 and Figure 6The A-end clamping mechanism 41 includes a clamping jaw A411, a clamping jaw cylinder A414 that drives the clamping jaw A411 to open and close, and a motor A416 that drives the clamping jaw A411 to rotate. The clamping jaw A411 is connected to the rotating ring 412, and the rotating ring 412 is connected to the fixed ring 413. The output shaft of the motor A416 is connected to the rotating ring 412 and drives the rotating ring 412 to rotate. The clamping jaw cylinder A414 is fixedly connected to the fixed ring 413, and the gas pipeline of the clamping jaw cylinder A414 passes through the inside of the fixed ring 413 and the rotating ring 412 and is connected to the clamping jaw A411. The motor A416 drives the rotating ring 412 to rotate, thereby driving the clamping jaw A411 to rotate. The advantage of the rotatable clamping jaw A411 is that when the clamping jaw A411 clamps the tip of the rod for strength testing, the tip of the rod can be rotated to a certain angle such as 90°, 180°, and 270° to perform strength testing on different sides of the tip of the rod, and the detection is more comprehensive. The angle adjustment mechanism 42 includes a rotating shaft 421 and a rotating actuator. The rotating shaft 421 is connected to the A-end clamping mechanism 41 and is driven by a servo motor 424. The output shaft of the servo motor 424 is connected to the rotating shaft 421 via a coupling 422. The rotating shaft 421 is supported by a bearing seat 423. The jaw cylinder A414 of the A-end clamping mechanism 41 is fixed to the cylinder connecting plate 415, and the rotating shaft 421 is fixed to the cylinder connecting plate 415. The servo motor 424 drives the rotating shaft 421 to rotate, which in turn drives the cylinder connecting plate 415 to rotate, thereby rotating the A-end clamping mechanism 41.

[0035] See also Figure 5 、 Figure 9 and Figure 10 The B-end clamping mechanism 43 includes a clamping jaw B431 and a clamping jaw cylinder B432 for controlling the opening and closing of the clamping jaw B431. A pressure sensor 433 is provided at the clamping jaw B. The Z-direction shifting mechanism 44 is a linear module, the clamping jaw cylinder B432, and the module slider 441 are connected. The module motor 443 drives the module slider 441 to move along the module slide rail 442. Figure 5In the figure, a indicates that the B-end clamping mechanism 43 is located at the bottom end of the linear module, and b indicates that the B-end clamping mechanism 43 moves upward along the module slide rail 442. The X-direction shifting mechanism 45 includes an X-direction slide rail 451 and an X-direction slider 452 that moves along the X-direction slide rail 451. The linear module is connected to the movable side connecting plate 444. The X-direction slider 452 is set on the movable side connecting plate 444. The movable side connecting plate 444 is connected to the synchronous belt 453 via the synchronous belt connecting plate 455. The synchronous belt 453 is driven by the motor B454 to drive the movable side connecting plate 444 to move, thereby moving the B-end clamping mechanism 43 along the X-direction. During the displacement process of the B-end clamping mechanism 43 along the Z-direction and X-direction, the A-end clamping mechanism 41 and the B-end clamping mechanism 43 perform a strength test on the bending of the clamping rod tip. The rod tip rope used to fix the line group is fixed to the end of the rod tip with epoxy resin. If the rod tip rope is not firmly bonded, the rod tip rope is likely to fall off and the line group is lost during fishing. While testing the strength of the rod tip, the tension of the rod tip rope can also be measured using the fishing rod tip strength testing machine of the present invention. The clamping jaw A411 clamps the thick end of the rod tip section, and the clamping jaw B431 clamps the rod tip rope and moves away from the clamping jaw A411 under the action of the X-direction shifting mechanism 4, pulling the rod tip rope. The pressure sensor 433 senses the change in tension. If the preset force value is reached and the rod tip rope is not broken, it is judged that the rod tip rope is bonded properly, and the strength test of the rod tip is continued.

[0036] See also Figure 2 、 Figure 5 and Figure 8 A defective product receiving hopper 10 that can be displaced in the Y direction is provided below the A-end clamping mechanism 41 and the B-end clamping mechanism 43. A receiving box 12 for receiving qualified rod tips is provided below the defective product receiving hopper 10. A discharge blocking piece 9 is provided at the corresponding position where the A-end clamping mechanism 41 and the B-end clamping mechanism 43 release the rod tip. The discharge blocking piece 9 guides the rod tip into the defective product hopper or the receiving box 12. The defective material receiving hopper 10 is connected to the material receiving hopper shift cylinder 11. When the A-end clamping mechanism 41 and the B-end clamping mechanism 43 of the detection device 4 clamp the rod tip for detection, if the rod tip is qualified, the defective material receiving hopper 10 will not be pushed out, and the qualified rod tip will directly fall into the material receiving box 12; if the rod tip breaks, the module motor 443 that drives the module slider 441 to move senses the change in torque, and the control system will control the material receiving hopper shift cylinder 11 to move the defective material receiving hopper 10 to push it out and move it to the bottom of the detection rod tip. The defective rod tip released by the A-end clamping mechanism 41 and the B-end clamping mechanism 43 falls into the defective material receiving hopper 10, so that the defective rod tip and the qualified rod tip are stored separately in the defective material receiving hopper 10 and the material receiving box 12, making subsequent processing more convenient.

[0037] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
