Abstract
Description
Technical Field
[0001] This utility model relates to the field of automation equipment technology, and specifically to a fishhook clamping device used in automatic line-tying equipment. Background Technology
[0002] See Figure 1 As shown, a common fishing hook 9 includes a shank 91 and a curved hook 92. The fishing line includes a leader and a main line. The hook 9 is connected to the main line via the leader 90. Currently, the connection between the hook and the leader 90 is done manually. Regardless of the binding method used, the leader needs to be knotted. Because the leader is thin, stress concentration easily occurs at the knot during fishing, making it the weakest point and prone to breakage. Furthermore, manual knotting is inefficient, so most hook manufacturers now use automated equipment for knotless binding. See utility model patent number 2023215547862, which discloses "a novel knotless fishing hook".
[0003] When using automated equipment to tie fishing lines to hooks, the hook 9 needs to be clamped, and then the fishing line is wound and tied to the shank 91 of the hook 9. Currently, most hook clamps in automated equipment clamp the hook at the bend 92. This clamping method is used not only to facilitate the winding of the fishing line at the shank 91, but also because the bend at the bend 92 provides greater stability and prevents the hook from rotating. However, this method also has the following drawbacks: the bend 92 of the hook is not on the same plane, and the bend of existing hooks often has a certain degree of deflection. This can cause the bend 92 to deform under clamping pressure during the clamping process, making it easy for the fish to escape during fishing. To avoid clamping deformation, hook clamps must be specifically manufactured for different hook models, which increases the cost of the clamps and requires constant replacement, resulting in low production efficiency.
[0004] In view of the shortcomings of existing fishhook clamps in tying equipment, the inventors propose the following technical solution. Summary of the Invention
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a fishhook clamping device for automatic line binding equipment. The clamping device stably clamps the fishhook at the shank position and can clamp various types of fishhooks, thereby reducing costs.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a fishhook clamping device for an automatic tying equipment, comprising: a drive base and a clamp mounted on the drive base; the drive base has a drive motor for driving the clamp to rotate, and the clamp includes: a clamp seat connected to the drive motor, the front end of the clamp seat away from the drive motor having a protrusion, and a movable clamping block pivotally connected to the side of the protrusion, the protrusion and the movable clamping block forming a clamping space for clamping the fishhook shank; the clamp seat is also provided with a cam mechanism connected to the movable clamping block, and the cam mechanism drives the movable clamping block to clamp or release the protrusion, thereby realizing the clamping or releasing of the fishhook.
[0007] Furthermore, in the above technical solution, the protrusion has a fixed clamping surface, the movable clamping block has a movable clamping surface corresponding to the fixed clamping surface, and a hook shank groove corresponding to the hook shank is formed on either the fixed clamping surface or the movable clamping surface. This hook shank groove positions the hook shank of the fishhook.
[0008] Furthermore, in the above technical solution, a blocking surface is formed above the fixed clamping surface or the movable clamping surface, and the side of the hook of the fishhook held by the clamping space interferes with the blocking surface.
[0009] Furthermore, in the above technical solution, a first limiting block is fixed on the protrusion, and the first limiting block extends upward to form a limiting piece corresponding to the end position of the protrusion, and the side of the limiting piece constitutes the blocking surface.
[0010] Furthermore, in the above technical solution, the hook shank groove is formed on the movable clamping surface, and a second limiting block is provided above the movable clamping block. The second limiting block extends towards the fixed clamping surface to form a blocking block located above the hook shank groove; the blocking block limits and blocks the bent hook of the fish hook clamped through the clamping space.
[0011] Furthermore, in the above technical solution, a guide shaft is provided between the protrusion and the movable clamping block.
[0012] Furthermore, in the above technical solution, the clamp seat has a mounting groove in the transverse direction and a camshaft hole in the longitudinal direction; the movable clamping block includes a clamping part, a positioning part, and a pivot part, the movable clamping surface is located on the clamping part, the positioning part is integrally formed with the clamping part and inserted into the mounting groove, a pivot is provided on the pivot part connected to the positioning part, and the pivot part is pivotally connected to the mounting groove through the pivot; the cam mechanism includes a camshaft installed in the axle hole, and a lever located below the clamp seat and fixed relative to the camshaft, the camshaft has a shaft diameter change point formed, which interferes with the pivot part in the movable clamping block; by moving the lever, the camshaft rotates, and the shaft diameter change at the shaft diameter change point pushes the pivot part, causing the movable clamping block to swing along the pivot, thereby causing the movable clamping block to clamp or loosen with the protrusion.
[0013] Furthermore, in the above technical solution, one end of the pivot of the movable clamping block is connected to the positioning part by a screw, and the other end of the pivot is provided with an elastic contact part at the position where it interferes with the change of shaft diameter; an opening clamping cylinder and a closing clamping cylinder are provided at different positions of the drive seat, and the opening clamping cylinder and the closing clamping cylinder push the paddle to make the camshaft rotate.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:
[0017] 1. Unlike existing fishhook clamps, this invention does not clamp the hook's bend, but instead clamps it directly to the hook shank near the bend. This way, the hook's bend is not subjected to clamping force and will not deform. Furthermore, while the bend varies considerably among different hook models, the shank differences are minimal. Therefore, the same clamping device can clamp different hook models, reducing production costs and the frequency of clamping device replacement.
[0018] 2. In order to further clamp the fish hook, the utility model limits the hook shank of the fish hook by means of the hook shank groove, and at the same time uses the blocking surface and the blocking block to position the clamped fish hook, so as to prevent the fish hook from falling off or deflecting during the subsequent winding operation, and to form a stable clamping of the fish hook.
[0019] 3. This utility model can realize automated operation. The movable clamping block used to hold the fish hook is driven by a cam mechanism. The cam mechanism can be driven by opening and closing cylinders in different positions. The opening and closing cylinders push the cam mechanism to drive the movable clamping block to rotate, thereby clamping or releasing the fish hook. The whole process does not require manual operation and can realize automated operation.
[0020] 4. This utility model also integrates a line clamping mechanism, which is directly installed on the clamping device's fixture seat. The fishhook's leader line and the binding line used to fix the leader line are clamped by the clamping mechanism and rotate with the entire clamping device, facilitating the winding operation.

[0029] The present invention will be further described below with reference to specific embodiments and accompanying drawings.
[0030] This utility model relates to a fishhook clamping device used in automatic line-tying equipment. See Figures 1 to 4 As shown, the clamping device includes: a drive base 1, a clamp 2 mounted on the drive base 1, and an opening clamping cylinder 201 and a closing clamping cylinder 202 located at different positions.
[0031] The drive base 1 includes a base 10 and a drive motor 11 mounted on the base 10. The base 10 is a support body, and the drive motor 11 is a servo motor used to drive the clamp 2 to rotate. During the rotation of the clamp 2 that holds the fish hook 9, the tie line binds the leader line to the hook shank of the fish hook 9.
[0032] See Figures 5 to 8 As shown, the clamp 2 includes: clamp base 21, protrusion 22, movable clamping block 23, cam mechanism 24 and wire clamping mechanism 25.
[0033] The fixture base 21 has a mounting groove 210 in the transverse direction and a camshaft hole 211 and a pivot hole 212 in the longitudinal direction.
[0034] Combination Figure 5 As shown, the output end of the drive motor 11 is provided with a rotating shaft 12, the front end of which is fixedly connected to the rear end of the clamp seat 21 in the clamp 2. When the drive motor 11 is working, it drives the rotating shaft 12 and the clamp seat 21 fixed to the rotating shaft 12 to rotate. In order to further determine the number of rotations and angle of the clamp 2, a trigger plate 130 is fixed on the rotating shaft 12 or the clamp seat 21, and a trigger switch 13 is provided on the base 10. The trigger switch 13 can be a photoelectric switch. When the trigger plate 130 rotates with the rotating shaft 12 or the clamp seat 21, it is triggered by the trigger switch 13, which can accurately determine the number of rotations and angle of the clamp 2.
[0035] The protrusion 22 is fixed or integrally formed on the front end of the clamping base 21 away from the drive motor 11, and the front end of the protrusion 22 is wedge-shaped. The side of the protrusion 22 forms a fixing clamping surface 220. A blocking surface 260 is formed above the fixing clamping surface 220.
[0036] A movable clamping block 23 is installed on the clamping base 21 at a position next to the protrusion 22. The movable clamping block 23 has a movable clamping surface 230 corresponding to the fixed clamping surface 220. The protrusion 22 and the movable clamping block 23 form a clamping space for clamping the shank 91 of the fishhook 9. Specifically, this clamping space is located between the fixed clamping surface 220 and the movable clamping surface 230. During operation, the shank 91 of the fishhook 9 is clamped within the clamping space.
[0037] The cam mechanism 24 is mounted on the clamp seat 21. The cam mechanism 24 is used to push the movable clamping block 23 to swing, thereby realizing the clamping and releasing of the clamping space, and realizing the clamping or releasing of the fish hook 9.
[0038] Unlike existing fishhook clamps, this invention does not clamp the curved part of the fishhook, in order to achieve positioning of the fishhook 9. Combined with... Figure 8As shown, a hook shank groove 2301 corresponding to the hook shank 91 is formed on the movable clamping surface 230. The hook shank groove 2301 is used to accommodate the hook shank 91, and the hook shank 91 is limited by the hook shank groove 2301 to prevent the fish hook 9 from rotating when winding the line. Of course, the hook shank groove 2301 can also be provided on the fixed clamping surface 220, or simultaneously at corresponding positions on both the fixed clamping surface 220 and the movable clamping surface 230.
[0039] In operation, the hook 92 varies considerably among different models of fishhooks 9, but the hook shank 91 remains largely the same. This means that the same hook shank groove 2301 can accommodate clamping adaptations for various fishhooks. Therefore, the same clamping device can clamp different models of fishhooks, reducing production costs and the frequency of clamping device replacement.
[0040] Since the clamping space clamps the shank 91 of the fishhook 9, which is roughly axial in shape, it is easily rotated during the winding process due to the direct clamping of the fixed clamping surface 220 and the movable clamping surface 230. To further clamp the fishhook and limit its rotation, this invention employs the following method: a blocking surface 260 is formed above the fixed clamping surface 220 or the movable clamping surface 230. The side of the hook 92 of the fishhook 9 clamped in the clamping space interferes with the blocking surface 260, thus preventing the fishhook 9 from rotating even when subjected to torque during winding.
[0041] In this embodiment, the blocking surface 260 is disposed on the fixed clamping surface 220. Specifically, a first limiting block 26 is fixed on the protrusion 22, and the first limiting block 26 extends upward to form a limiting piece 261 corresponding to the end position of the protrusion 22. The side of the limiting piece 261 constitutes the blocking surface 260.
[0042] Additionally, a second limiting block 27 is provided above the movable clamping block 23. This second limiting block 27 extends towards the fixed clamping surface 220 to form a blocking block 270 located above the hook shank groove 2301. Figure 5 As shown, when the fishhook 9 is clamped in the clamping space, the blocking block 270 is located just in front of the hook 92 of the fishhook 9, thereby limiting and blocking the hook 92 of the fishhook 9 clamped by the clamping space, preventing the fishhook from leaving the clamping space in the front-back direction.
[0043] The first limiting block 26 and the second limiting block 27 mentioned above can be set independently and then fixed on the upper surface of the protrusion 22 and the movable clamping block 23 respectively. Of course, they can also be integrally formed on the protrusion 22 and the movable clamping block 23.
[0044] The movable clamping block 23 includes a clamping part 231, a positioning part 232, and a pivoting part 23. The clamping part 231 corresponds to the protrusion 22, and the front end of the clamping part 231 is also wedge-shaped. The movable clamping surface 230 is located on the side of the clamping part 231. The second limiting block 27 is fixedly connected to the upper end face of the clamping part 231.
[0045] The positioning part 232 and the clamping part 231 are integrally formed and inserted into the mounting groove 210. A pivot 2330 is provided on the pivot part 233 connected to the positioning part 232. Specifically, a pivot hole 212 is formed on the clamping base 21 in the longitudinal direction, and the pivot part 233 is pivotally connected to the mounting groove 210 through the pivot hole 212 via the pivot 2330.
[0046] The cam mechanism 24 is mounted on the clamp seat 21. The cam mechanism 24 is used to push the movable clamping block 23 to swing. The clamping part 231 in the movable clamping block 23 opens or closes relative to the protruding part 22, thereby realizing the clamping and loosening of the clamping space and realizing the clamping or loosening of the fish hook 9.
[0047] The clamping part 231 and the positioning part 232 can be fixedly connected or connected in an adjustable manner. An adjustable connection allows adjustment of the relative gap between the fixed clamping surface 220 and the movable clamping surface 230, enabling fine-tuning for different fishhook models. Specifically, one end of the pivot part 233 of the movable clamping block 23 is connected to the positioning part 232 via a screw 2331. By adjusting the feed of the screw 2331, the clamping part 231 and the positioning part 232 are displaced along the axial direction of the screw 2331, thereby allowing fine-tuning of the relative gap between the fixed clamping surface 220 and the movable clamping surface 232 according to different fishhook models.
[0048] To ensure precise alignment of the clamping part 231 relative to the protrusion 22 during opening or closing, a guide shaft 28 is provided between the protrusion 22 and the clamping part 231. Specifically, a guide shaft 28 is fixed at the front end of the protrusion 22, and a guide hole 2310 is provided at the front end of the clamping part 231 corresponding to the position of the guide shaft 28. Through the shaft-hole cooperation between the guide shaft 28 and the guide hole 2310, the movable clamping block 23 achieves accurate alignment during swinging and will not deviate.
[0049] The cam mechanism 24 includes a camshaft 241 installed in the wheel axle hole 211 and a lever 242 located below the clamp seat 21 and fixed relative to the camshaft 241. The camshaft 241 has a diameter change portion 2410 formed on it, which interferes with the pivot portion 233 in the movable clamp 23. By moving the lever 242, the camshaft 241 is rotated, and the diameter change of the diameter change portion 2410 pushes the pivot portion 233, causing the movable clamp 23 to swing along the pivot 2330, thereby causing the movable clamp 23 to clamp or loosen with the protrusion 22.
[0050] Specifically, the diameter change point 2410 can be formed directly by creating a notch on the camshaft 241, or it can be formed by setting a cam block. This diameter change point 2410 abuts against the side of the pivot portion 233 of the movable clamping block 23. To avoid rigid contact, an elastic contact portion 2332 is provided in the pivot portion 233 at the position abutting against the diameter change point 2410. This elastic contact portion 2332 is achieved by creating a gap groove on the side of the pivot portion 233.
[0051] The cam mechanism 24 rotates the camshaft 241 by actuating the lever 242. When the clamp 2 is working, the entire clamp 2 will rotate. To achieve automatic actuation of the lever 242, this invention utilizes opening cylinders 201 and closing cylinders 202 located at different positions. Specifically, in conjunction with... Figure 4 As shown, the clamping cylinder 201 is located on the side of the clamp 2, and the clamping cylinder 202 is located below the clamp 2. During operation, when the clamp 2 needs to clamp the fishhook 9, it first rotates to a horizontal position. At this time, the lever 242 is located below the clamp base 21. The clamping cylinder 201 is activated, pushing the lever 242 to swing, causing the movable clamping block 23 to clamp relative to the protrusion 22. When the clamp 2 needs to release the fishhook 9, it first rotates to a position 90° relative to the horizontal position. At this time, the lever 242 is located on the side of the clamp base 21. The clamping cylinder 202 is activated, pushing the lever 242 to swing, causing the movable clamping block 23 to release relative to the protrusion 22.
[0052] Since the clamping cylinder 201 and the clamping cylinder 202 are relatively independent and not directly connected to the clamp 2, the clamp 2 will not be affected when it rotates. The clamping device can be automatically operated through the electronic control device.
[0053] In addition, a line clamping mechanism 25 is also installed on the clamping base 21. The line clamping mechanism 25 is used to clamp the leader line 90 of the fishhook 9 and the binding line. When binding the line to the fishhook 9, the leader line 90 should be fixed relative to the fishhook, that is, one end of the leader line 90 is clamped by the line clamping mechanism 25, and the other end is clamped by another line clamping mechanism (not shown in the figure). The leader line 90 is close to the hook shank 91 of the fishhook and parallel to the axis of the hook shank 91. One end of the binding line is clamped by the line clamping mechanism 25, and the other end is located next to the hook shank 91 by the line feeding mechanism. When the clamp 2 starts to rotate and slide the wire, the binding line will be wrapped around the hook shank 91. At the same time, the leader line and the hook shank 91 are bound together by the binding line. After applying glue and curing, the binding line can be cut.
[0054] Specifically, the wire clamping mechanism 25 includes a left clamping piece 251, a right clamping piece 252, and a middle clamping block 253. The middle clamping block 253 is movably inserted into the clamping base 21. The clamping base 21 has a longitudinally oriented insertion hole 213 corresponding to the middle clamping block 253, and the lower end of the middle clamping block 253 is inserted into the insertion hole 213. The middle clamping block 253 has locking blocks 2531 on its left and right sides, each with an arc shape. The left clamping piece 251 and the right clamping piece 252 have corresponding left and right locking slots, forming a rotatable locking connection with the corresponding locking blocks 2531. The left clamping piece 251 extends outward to form a clamping handle. When the clamping handle is pressed down, the left clamping piece 251 swings, thereby pushing the middle clamping block 253 up and down. Simultaneously, the up and down movement of the middle clamping block 253 pushes and drives the right clamping piece 252 to swing.
[0055] The hook's leader 90 and binding line are held by the left clamp 251 and the middle clamp 253, and the right clamp 252 and the middle clamp 253, respectively. In use, firstly, when the external cylinder presses down on the handle of the left clamp 251, the gap between the left clamp 251 and the middle clamp 253 is loosened, and the gap between the right clamp 252 and the middle clamp 253 is opened. At this point, the corresponding leader 90 and binding line are inserted. Then, when the external cylinder opens the handle of the left clamp 251, the elastic restoring force of the middle clamp 253 causes it to return to its original position and move downwards, thereby clamping the leader and binding line tightly.
[0056] The elastic reset force of the intermediate clamping block 253 can be achieved by components such as springs, or by other structures. For example, in this embodiment, it is generated by the left clamping piece 251. Specifically, an elastic arm is formed on one side of the clamping handle extending outward from the left clamping piece 251. This elastic arm cooperates with the clamping block on the clamping seat 21, and the elastic reset force is generated on the left clamping piece 251 through the interference between the clamping block and the elastic arm.
[0057] In summary, this invention uses a direct clamping mechanism on the fishhook shank near the hook bend, thus eliminating clamping force on the hook bend and preventing deformation. Furthermore, while the bend varies considerably among different fishhook models, the shank differences are minimal. Therefore, the same clamping device can clamp different fishhook models, reducing production costs and the frequency of clamping device replacement.
[0058] To further clamp the fishhook, the utility model limits the hook shank by using a hook shank groove, and uses a blocking surface and blocking block to position the clamped fishhook, preventing it from falling off or deflecting during subsequent line winding operations, thus forming a stable clamp on the fishhook.
