Technical Field

[0001] The utility model relates to the technical field of fishhook feeding mechanisms, in particular to a fishhook feeding mechanism with the function of detecting whether a fishhook has reached a grabbing position. Background Art

[0002] At present, there are few automated fishhook production equipment on the market, and the mechanization level of the equipment needs to be improved. The patent document with patent application number CN202310298827.4 discloses a fishhook sorting and feeding device, which also realizes the automated sorting and feeding functions of the fishhook; however, when the fishhook reaches the grabbing position of the unloading manipulator, if the fishhook is severely extended, it is easy to fall off; if the fishhook does not reach the grabbing position of the unloading manipulator, the unloading manipulator will not be able to grab the fishhook normally. In other words, making the fishhook accurately reach the grabbing position of the unloading manipulator is the key to improving the precise feeding function of the fishhook feeding mechanism. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a fishhook feeding mechanism with the function of detecting whether the fishhook has reached the grabbing position, which can enable the fishhook to accurately reach the grabbing position of the unloading robot.

[0004] The purpose of the utility model is achieved by the following technical solutions:

[0008] An in-place sensor is accommodated in the avoidance groove; a detection head of the in-place sensor is used to detect whether the fishhook leaks out of the first guide groove;

[0009] The control system, the fishhook pushing structure and the in-place sensor are both electrically connected to the control system.

[0010] Furthermore, the in-position sensor is a matrix optical fiber.

[0011] Furthermore, the fishhook guide structure includes a support seat, a lifting compensation seat and an elastic reset member; the lifting compensation seat is supported by the support seat and forms a first guide groove between the lifting compensation seat and the support seat; the elastic reset member is connected to the lifting compensation seat and is used to drive the lifting compensation seat to approach the support seat to reduce the width of the first guide groove.

[0012] Furthermore, the fishhook guiding structure also includes a guiding ramp seat, which is connected to the supporting seat, and has a slope surface, and the slope surface and the first guiding groove are connected in sequence along the conveying direction of the fishhook, and the slope surface is used to guide the fishhook so that the fishhook can be switched from a vertical hanging state to a horizontal placement state.

[0013] Furthermore, the support seat is connected to a first magnetic attraction structure, and the first magnetic attraction structure is used to suck the fish hook tightly to remove the fish hook from the fish hook pushing structure.

[0014] Furthermore, the first magnetic attraction structure is embedded in the groove wall of the first guide groove.

[0015] Furthermore, the fishhook guiding structure also includes an auxiliary suction structure, and the auxiliary suction structure and the supporting seat are arranged opposite to each other in a horizontal direction.

[0016] Furthermore, the auxiliary clamping structure includes an auxiliary support and a second magnetic structure; the auxiliary support is provided with a second guide groove, the first guide groove and the second guide groove have the same extension direction and are arranged opposite to each other in the horizontal direction; the second magnetic structure is embedded in the groove wall of the second guide groove.

[0018] Furthermore, the support seat includes a base and a second bolt, the second bolt is threadedly connected to the base, the elastic reset member is a spring, the second bolt is passed through the spring, and both ends of the spring respectively abut against the nut of the second bolt and the lifting compensation seat.

[0019] Compared with the prior art, the beneficial effect of the utility model is that: by providing a first guide groove in the fishhook guide structure and also providing an avoidance groove in the fishhook guide structure, the fishhook needs to extend from the first guide groove, and the avoidance groove avoids the housing of the in-place sensor, so that the detection head of the in-place sensor can detect next to the outlet of the first guide groove. In this way, as long as the fishhook leaks out slightly, it can be detected by the in-place sensor in time, so that it will not be pushed out of the first guide groove by the fishhook pushing structure and fall. In other words, as long as the fishhook just reaches the position waiting to be caught, it can stop moving forward, thereby solving the problem of the fishhook falling.

The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0029] See also Figure 4 and Figure 5 The fishhook feeding mechanism with the function of detecting whether the fishhook has reached the grabbing position in a preferred embodiment of the utility model comprises: a fishhook guiding structure 1, a fishhook pushing structure 2, an arrival sensor 3 and a control system. Among them, the control system can be a single chip microcomputer and the like.

[0030] The fishhook guide structure 1 is provided with a first guide groove 11 , and is further provided with an avoidance groove 12 , which is recessed in a direction opposite to the first guide groove 11 guiding the fishhook.

[0031] The fishhook pushing structure 2 can support the fishhook and drive the fishhook to pass through the first guide groove 11 .

[0032] The in-position sensor 3 is accommodated in the avoidance groove 12 ; the detection head of the in-position sensor 3 is used to detect whether the fish hook leaks out of the first guide groove 11 .

[0033] The fishhook pushing structure 2 and the arrival sensor 3 are both electrically connected to the control system.

[0034] During operation, the vibrating plate 5 transports the fish hooks one by one in an orderly manner to the unloading guide rail 6, and then, referring to the structure and working principle of the existing single fish hook distributing mechanism, for example, referring to the patent document with patent application number CN202310298827.4, which discloses the structure and working principle of the single fish hook distributing mechanism of the fish hook distributing and feeding device, the single fish hook is peeled off to the fish hook pushing structure 2. After the fish hook pushing structure 2 drives the fish hook to pass through the first guide groove 11, the fish hook has just been detected by the in-place sensor 3 when it extends out of the first guide groove 11. Then, the control system receives the signal of the in-place sensor 3, and then controls the fish hook pushing structure 2 to stop moving forward, and then waits for the unloading manipulator to take the fish hook away from the fish hook pushing structure 2.

[0035] Importantly, by providing the first guide groove 11 and the avoidance groove 12 in the fishhook guide structure 1, the fishhook needs to extend from the first guide groove 11, and the avoidance groove 12 avoids the housing of the in-place sensor 3, so that the detection head of the in-place sensor 3 can detect next to the outlet of the first guide groove 11. In this way, as long as the fishhook leaks out slightly, it can be detected by the in-place sensor 3 in time, so that it will not be pushed out of the first guide groove 11 by the fishhook pushing structure 2 and fall. In other words, as long as the fishhook just reaches the position waiting to be caught, it can stop moving forward, thereby solving the problem of the fishhook falling.

[0036] In this embodiment, preferably, the in-position sensor 3 is a matrix optical fiber or a grating sensor or the like.

[0037] In this embodiment, see Figure 1 and Figure 2 Preferably, the fishhook guide structure 1 includes a support seat 13, a lifting compensation seat 14 and an elastic reset member 15; the lifting compensation seat 14 is supported by the support seat 13 and forms a first guide groove 11 with the support seat 13; the elastic reset member 15 is connected to the lifting compensation seat 14 and is used to drive the lifting compensation seat 14 to approach the support seat 13 to reduce the groove width of the first guide groove 11. When the fishhook is ready to be sent into the first guide groove 11 from the fishhook pushing structure 2, if the cross-sectional diameter of the fishhook is too large (i.e., the fishhook specification is large), the lifting compensation seat 14 moves upward, thereby expanding the groove width of the first guide groove 11, so that the fishhook can enter the first guide groove 11; if the cross-sectional diameter of the fishhook is just equal to or slightly smaller than the first guide groove 11, the lifting compensation seat 14 is not pushed and remains motionless; at this time, the fishhook is guided and clamped by the support seat 13 and the lifting compensation seat 14, so it is not easy to fall off. When the hook part of the fishhook leaks out of the first guide groove 11, the fishhook pushing structure 2 stops moving forward, waiting for the unloading manipulator to clamp the hook part of the fishhook and take the fishhook away. Moreover, after the fishhook enters the first guide groove 11, its state is also switched from a vertical placement state to a horizontal placement state, which is more conducive to the unloading manipulator to reach out horizontally to grab it, retreat, and then transport the fishhook away. In this way, by adding a fishhook guide structure 1 to the fishhook delivery path, and defining the first guide groove 11 between its support seat 13 and the lifting compensation seat 14, under the compensation of the elastic reset member 15, the support seat 13 and the lifting compensation seat 14 can approach or move away from each other, so that the fishhook can be guided and clamped, so that the fishhook is not easy to fall off. In addition, based on the fact that the support seat 13 and the lifting compensation seat 14 can approach or move away from each other, the first guide groove 11 is also suitable for fishhook of various specifications (i.e., different cross-sectional diameters).

[0038] In this embodiment, see Figure 2 Preferably, the fishhook guide structure 1 further comprises a guide ramp seat 16, the guide ramp seat 16 is connected to the support seat 13, and the guide ramp seat 16 has a slope surface 161 (see Figure 3 ), the slope surface 161 and the first guide groove 11 are connected in sequence along the conveying direction of the fish hook, and the slope surface 161 is used to guide the fish hook so that the fish hook is switched from a vertical hanging state to a horizontal placement state. With this arrangement, when the fish hook is pushed forward by the fish hook pushing structure 2, it first passes through the slope surface 161 of the guide slope seat 16, and the tip or tail rod of the fish hook is lifted by the slope surface 161, so that the fish hook gradually tilts until the tip or tail rod of the fish hook enters the first guide groove 11 horizontally, and the bent hook part of the fish hook is still pushed forward by the fish hook pushing structure 2. With this arrangement, the fish hook is smoothly adjusted from a vertical placement state to a horizontal placement state during transportation, so that it can enter the first guide groove 11 more smoothly to further prevent the fish hook from falling off.

[0039] In the present embodiment, preferably, the support seat 13 is connected with a first magnetic structure 17, and the first magnetic structure 17 is used to suck the fishhook tightly so as to remove the fishhook from the fishhook pushing structure 2. Among them, the first magnetic structure 17 can be a natural magnet, or an artificial magnet, etc. When the fishhook pushing structure 2 sends the fishhook into the first guide groove 11, the tip of the fishhook or the tail rod of the fishhook is sucked tightly by the first magnetic structure 17, until the fishhook pushing structure 2 pushes the fishhook to the bent hook part of the fishhook and leaks out of the first guide groove 11, and the fishhook pushing structure 2 retreats. Based on the ability of the first magnetic structure 17 to suck the fishhook tightly, the friction between the fishhook pushing structure 2 and the fishhook is not enough to drag the fishhook backward, so that the fishhook can be positioned at a specific position so that the unloading robot can accurately grab the fishhook.

[0040] In this embodiment, in order to make the first magnetic structure 17 fully contact with the fishhook, thereby strengthening the adsorption force of the first magnetic structure 17 on the fishhook, preferably, the first magnetic structure 17 is embedded in the groove wall of the first guide groove 11. In this way, when the fishhook moves forward along the first guide groove 11, it will contact with the first magnetic structure 17 and be supported by the first magnetic structure 17, so that it can be stably attracted to prevent the fishhook from being dragged back.

[0041] In this embodiment, see Figure 5 Preferably, the fishhook guide structure 1 further comprises an auxiliary suction structure 4, and the auxiliary suction structure 4 and the support seat 13 are arranged oppositely in the horizontal direction. And, in this embodiment, preferably, the auxiliary suction structure 4 comprises an auxiliary support 41 and a second magnetic structure 42; the auxiliary support 41 is provided with a second guide groove 411, and the first guide groove 11 and the second guide groove 411 extend in the same direction and are arranged oppositely in the horizontal direction; the second magnetic structure 42 is embedded in the groove wall of the second guide groove 411. In this arrangement, when the fishhook is pushed into the first guide groove 11 by the fishhook pushing structure 2, if the tip of the fishhook is located in the first guide groove 11, the tail rod of the fishhook is located in the second guide groove 411; if the tip of the fishhook is located in the second guide groove 411, the tail rod of the fishhook is located in the first guide groove 11; the advantage of this arrangement is that the fishhook is supported by the fishhook pushing structure 2, the support seat 13 and the auxiliary suction structure 4 at the same time to maintain a horizontal placement state, so it is more difficult to fall off. Moreover, when the fishhook is pushed into place by the fishhook pushing structure 2, one of the tip of the fishhook and the tail rod of the fishhook is sucked by the first magnetic structure 17, and the other is sucked by the second magnetic structure 42, so it is more stable, that is, it can wait more stably for the unloading robot to take away the fishhook.

[0042] In this embodiment, see Figure 2Preferably, the fishhook pushing structure 2 includes a feeding linear drive mechanism 21 and a feeding plate 22; the feeding plate 22 has a fishhook inverted support portion 221 and a fishhook pushing portion 222, the fishhook inverted support portion 211 is used to provide the fishhook barb, and the fishhook pushing portion 222 is used to abut and push the fishhook to transport the fishhook to the exit of the first guide groove 11. During operation, the feeding plate 22 retreats backward until the hook inverted support 221 is located directly below the unloading guide rail 6, and then the blocking block 7 is driven away from the unloading guide rail 6 by an external linear motion driving source (such as a linear motor or a patent document with reference to patent application number CN202310298827.4 that discloses a hook distribution and feeding device) to release a hook and slide it onto the hook inverted support 221. Then, the hook pusher 222 moves forward, so that the hook falls into the pit enclosed by the hook pusher 222 and the hook inverted support 221, and is pushed forward by the hook pusher 222. It can be understood that, as an alternative setting, the hook pusher structure 2 can be a combination of a linear drive mechanism and a horizontal moving rod, which can be moved by the horizontal moving rod, thereby dragging the hook to move horizontally.

[0043] In this embodiment, preferably, the support seat 13 includes a base 131 and a second bolt 132, the second bolt 132 is threadedly connected to the base 131, the elastic reset member is a spring, the second bolt 132 is inserted into the spring, and the two ends of the spring respectively abut against the nut of the second bolt 132 and the lifting compensation seat 14. In this way, by adjusting the second bolt 132, the squeezing force of the elastic reset member 15 on the lifting compensation seat 14 can be adjusted to ensure that the fishhook can enter the first guide groove 11 without affecting its forward movement.

[0044] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
