Description

[0002] The knob of a fishing rod is located at the top or side of a fishing reel and is used to control the resistance of the line. When the fishing strength is not suitable or the line is cut, the knob is used to adjust the resistance. The current fishing rod knob is assembled by setting an aluminum belt type conveying device above the rack, installing a jig for placing the knob above the conveying device, setting a slot matching the size of the knob on the jig for placing the knob, and setting multiple vibrating feeders to feed the multiple components of the knob. During assembly, the jig passes under the multiple vibrating feeders under the action of the conveying device, and a mechanical hand picks up the components in the vibrating feeders and places them on the jig for assembly. Since the knob is directly inserted into the slot of the jig for positioning and fixing, the inner diameter of the slot of the jig increases after long-term repeated friction with the knob. When the knob is placed in the slot of the jig, the position of the knob inside the jig will shift due to vibration during movement, which cannot guarantee that the components of the knob are in the middle of the slot. During the assembly of the remaining components, it is difficult to ensure that the subsequent parts are accurately inserted into the previous components, which affects the precision during subsequent assembly.

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments.

[0017] Referring to Figures 1-8 , the automatic fish reel brake knob assembly device comprises a rack 1, two groups of vibrating trays 2 are arranged on the left side and the right side of the rack 1 respectively, four feeding manipulators 3 are arranged on the upper part of the rack 1 in a rectangular distribution, the four feeding manipulators 3 are respectively arranged at the tail end of the discharging structure of the four vibrating trays 2, a discharging manipulator 4 is arranged between the front two feeding manipulators 3, a rectangular moving track 5 is arranged on the upper part of the rack 1, a plurality of jigs 6 are arranged on the moving track 5 in a uniform distribution through sliding blocks, a positioning structure 7 for positioning the workpiece and a limiting structure 8 for limiting the positioning structure 7 are arranged on the jig 6, two expansion plates 11 are arranged on the upper part of the rack 1, one of the expansion plates 11 is arranged below the discharging manipulator 4, and the other expansion plate 11 is arranged below the left front feeding manipulator 3, the positioning structure 7 and the limiting structure 8 are in rolling contact with the expansion plate 11, the vibrating tray 2 on the left side and the front side is used for feeding the knob base and is the initial feeding point, the vibrating tray 2 on the left side and the rear side is used for feeding the knob spring, the vibrating tray 2 on the right side and the rear side is used for feeding the knob shaft sleeve, the vibrating tray 2 on the right side and the front side is used for feeding the knob torsion piece, and the jig 6 on the moving track 5 moves clockwise along the moving track 5.

[0018] Referring to Figures 1-3The four chain wheels 51 are arranged in a rectangular structure and are rotatably installed on the frame 1 through bearings and shafts. The four chain wheels 51 are respectively arranged at the four corners of the moving track 5. A chain 52 is installed between the four chain wheels 51. The jig 6 is connected with the chain 52. One of the chain wheels 51 is connected with the output shaft of an external precision divider through a shaft. The precision divider enables the chain wheel 51 connected with the output shaft to rotate intermittently. The jig 6 on the moving track 5 moves a unit distance each time the chain wheel 51 rotates, and the unit distance is the distance between two adjacent jigs 6.

[0019] With reference to Figures 3-6 A placing groove 61 is formed on the upper surface of the jig 6. A protruding groove 611 is formed at the bottom of the placing groove 61. The inner diameter of the placing groove 61 is greater than the outer diameter of the knob base. The depth, width and length of the protruding groove 611 are greater than the extension of the bottom of the knob base. When the knob base is placed in the placing groove 61 and the protruding groove 611, the knob base does not contact the placing groove 61, thereby avoiding abrasion between the two.

[0020] With reference to Figures 3-7 Two side plates 62 are symmetrically arranged on the two sides of the jig 6 and perpendicularly cross the moving track 5. The positioning structure 7 includes two positioning arc plates 71 symmetrically arranged in the placing groove 61. A clamping piece is fixed at the center of the side away from each other of the two positioning arc plates 71. A driving frame 73 is slidably installed above the two side plates 62. The clamping piece is rollingly connected with the driving frame 73. A driving wheel 76 is rotatably installed below the driving frame 73 through a shaft pin. The driving wheel 76 rollingly contacts the expansion plate 11.

[0021] A stand is welded on the driving frame 73. An opening is formed through the stand. A fixing rod 74 is slidably inserted into the opening. One end of the fixing rod 74 away from the stand is fixed with the jig 6. A positioning spring 75 is sleeved on the fixing rod 74. The two ends of the positioning spring 75 are respectively fixed with the jig 6 and the stand. The positioning spring 75 is a tension spring. The positioning spring 75 enables the stand to always have a tendency to move to the side of the jig 6. The driving frame 73 includes a T-shaped frame and two straight frames welded on the two sides of the T-shaped frame. The driving frame 73 has a fork structure. Two guide sliding blocks 733 are respectively arranged below the two straight frames. A guide sliding groove 621 is formed on the side plate 62. The guide sliding blocks 733 are slidably arranged in the guide sliding groove 621. The guide sliding blocks 733 guide the driving frame 73 to move linearly.

[0022] The jig 6 is provided with a circular hole on one side of the side plate 62, and the clamping part includes a clamping rod 72 slidingly inserted into the circular hole. The clamping rod 72 is rotatably installed with a clamping roller 721 below the end away from the positioning arc plate 71 through a shaft pin. The driving frame 73 is provided with a driving inclined groove 731. The distance between the driving inclined groove 731 close to the expansion plate 11 and the jig 6 is smaller than the distance between the driving inclined groove 731 away from the expansion plate 11 and the jig 6. The end of the driving inclined groove 731 away from the expansion plate 11 is provided with a horizontal groove which is horizontal to the jig 6. The expansion plate 11 includes a straight plate fixed on the rack 1 by screws. The straight plate is parallel to the adjacent moving track 5. The two ends of the straight plate are respectively designed to be inclined to form expansion inclined surfaces 12 towards one side of the moving track 5. When the jig 6 is below the feeding manipulator 3 at the initial feeding point, the driving wheel 76 is in contact with the middle of the straight plate. At this time, the two positioning arc plates 71 are away from each other, and the clamping roller 721 is at the end of the driving inclined groove 731 away from the expansion plate 11. When the jig 6 moves along the moving track 5 towards one side of the vibration tray 2 at the left rear side, the driving wheel 76 will roll along one expansion inclined surface 12 close to the vibration tray 2 at the left rear side. This will gradually reduce the distance between the driving wheel 76 and the jig 6. Since the positioning spring 75 makes the stand in the driving frame 73 always have a tendency to move towards the jig 6, when the stand moves towards the jig 6, the driving inclined groove 731 will also move as a whole towards the end away from the expansion plate 11, that is, the driving inclined groove 731 moves towards the end of the clamping roller 721. The vertical distance between the clamping roller 721 and the straight plate part does not change. Therefore, when the stand is close to the jig 6, the driving inclined groove 731 will move towards the side of the clamping roller 721 and press the clamping roller 721, so that the clamping roller 721 is close to the jig 6. The two clamping rollers 721 will simultaneously drive the two positioning arc plates 71 to move close to each other, so that the knob base placed between the two positioning arc plates 71 is clamped and fixed. The knob base is at the middle position of the placing groove 61, which is convenient for subsequent assembly and improves the positioning and assembly precision.

[0023] Reference Figures 3-8The driving frame 73 is provided with a plurality of limiting grooves 732 distributed at equal intervals. The limiting structure 8 comprises a side frame 811 fixed to the side plate 62. The lifting rod 81 is slidably inserted into the side frame 811. The lifting rod 81 is provided with a limiting head 82 at the top end. The limiting head 82 is in L-shaped structure. The limiting head 82 is provided with a limiting block above one side of the jig 6. The limiting block is in sliding contact with the outer surface of the jig 6. The limiting block can limit the rotation of the limiting head 82, so that the limiting head 82 can only move linearly upwards and downwards. The bottom end of the limiting head 82 is above the limiting groove 732. The lifting rod 81 is provided with a limiting spring 83. The two ends of the limiting spring 83 are fixed to the limiting head 82 and the side frame 811 respectively. The limiting spring 83 is a tension spring. The limiting spring 83 makes the limiting head 82 always have a downward moving trend.

[0024] The extension bottom plate 13 is provided with an unlocking slope 14 at both ends. The bottom end of the lifting rod 81 is rotatably installed with a moving wheel 812 through a shaft pin. The moving wheel 812 is in rolling contact with the extension bottom plate 13 and the unlocking slope 14. When the jig 6 is partially close to the extension plate 11, the moving wheel 812 will first contact one of the unlocking slopes 14. The moving wheel 812 will move above the extension bottom plate 13 through the unlocking slope 14. At this time, the lifting rod 81 is upward as a whole. The bottom end of the limiting head 82 moves out of the limiting groove 732 upward, which releases the limiting of the driving frame 73. At this time, the driving frame 73 can move freely, so that the driving frame 73 can move away from each other, which is convenient for taking down or placing the tuning knob base. After the moving wheel 812 moves above the extension bottom plate 13 along the unlocking slope 14, the driving wheel 76 can contact the extension plate 11.

[0025] The limiting groove 732 is designed as a lifting slope 734 towards the end slope of the T-shaped frame, and the lower end of the limiting head 82 is designed as a contact slope 821 towards the end slope of the T-shaped frame, which has the same slope as the lifting slope 734. When the jig 6 moves away from the expansion plate 11, the moving wheel 812 will move from above the extension bottom plate 13 to above the frame 1 along the unlocking slope 14 and contact the upper surface of the frame 1. In this process, the lifting rod 81 moves downward under the action of the limiting spring 83, and the limiting head 82 is inserted into the limiting groove 732. Since the limiting head 82 and the limiting groove 732 are respectively provided with the contact slope 821 and the lifting slope 734 towards the T-shaped frame, when the driving frame 73 moves inward to make the two positioning arc plates 71 close to each other, the limiting head 82 can slide upward along the lifting slope 734 through the contact slope 821, without limiting the inward movement of the driving frame 73 to close the jig 6. The limiting head 82 can limit the outward movement of the driving frame 73 away from the jig 6, that is, the two positioning arc plates 71 can only move close to each other but cannot move away from each other, avoiding the vibration of the two positioning arc plates 71 away from each other in the subsequent movement process, and improving the positioning accuracy.

[0026] Working principle: The knob base is placed on the left front vibrating tray 2, the knob spring is placed on the left rear vibrating tray 2, the knob shaft sleeve is placed on the right rear vibrating tray 2, and the knob torsion piece is placed on the right front vibrating tray 2. At this time, the driving wheel 76 on the jig 6 below the left front vibrating tray 2 and the jig 6 below the blanking manipulator 4 contact the middle of the straight plate. At this time, the two positioning arc plates 71 are away from each other, the opening size between the two positioning arc plates 71 is greater than the outer diameter of the knob base, the clamping roller 721 is away from the expansion plate 11 at one end of the driving inclined groove 731, the moving wheel 812 will move to above the extension bottom plate 13 through the unlocking slope 14, at this time the lifting rod 81 is upward as a whole, the bottom end of the limiting head 82 is above the limiting groove 732, and the limiting of the driving frame 73 is released.

[0027] In the actual process, the knob bases in the left front vibrating tray 2 will be arranged side by side on the discharging structure of the vibrating tray 2, and the upper feeding manipulator 3 will grab a knob base and place it into the placing groove 61 of the jig 6 below the upper feeding manipulator 3, and the knob base is located between the two positioning arc plates 71. Since the opening size between the two positioning arc plates 71 is greater than the outer diameter of the knob base, no contact occurs between them when placing, avoiding the wear of the inner wall of the positioning arc plate 71. After the precision divider makes the sprocket 51 connected with its output shaft intermittent rotation once, and further makes a plurality of sprocket 51 rotate once, the jig 6 will move one unit distance to the left rear side under the action of the sprocket 51 and the chain 52, when the jig 6 moves to the left rear side, the moving wheel 812 will move from above the extension bottom plate 13 to above the rack 1 along the unlocking slope 14 and contact with the upper surface of the rack 1, in the process, the lifting rod 81 moves downward under the action of the limiting spring 83, and the limiting head 82 is inserted into the limiting groove 732; At the same time, the drive wheel 76 will roll along an expansion slope 12 close to the left rear of the vibrating tray 2, which will gradually reduce the distance between the drive wheel 76 and the jig 6. Since the positioning spring 75 makes the stand in the drive frame 73 always have a tendency to move towards the side of the jig 6, when the stand in the drive frame 73 moves towards the end close to the jig 6, the drive slope 731 at this time will also move as a whole towards the end away from the inside of the expansion plate 11, that is, the drive slope 731 moves towards the end of the clamping roller 721, and the vertical distance between the clamping roller 721 and the straight plate part does not change. Therefore, when the stand is close to the jig 6, the drive slope 731 will move towards the side of the clamping roller 721 and press the clamping roller 721, so that the clamping roller 721 is close to the jig 6, and the two clamping rollers 721 will simultaneously drive the two positioning arc plates 71 to approach each other, thereby clamping and fixing the knob base placed between the two positioning arc plates 71, and the knob base is in the middle position of the placement slot 61, which is convenient for subsequent assembly and improves the positioning and assembly precision. After the jig 6 continues to move, since the limiting head 82 and the limiting groove 732 are respectively provided with a contact slope 821 and a lifting slope 734 towards the T-shaped frame, when the drive frame 73 moves inward to make the two positioning arc plates 71 approach each other, the limiting head 82 can slide upward along the lifting slope 734 through the contact slope 821, without limiting the drive frame 73 to move inward and close to the jig 6. The limiting head 82 can limit the drive frame 73 to move outward and away from the jig 6. Since the other side of the limiting head 82 and the limiting groove 732 is a vertical surface, they will abut each other, which makes the drive frame 73 unable to continue to move outward and away from the jig 6, that is, the two positioning arc plates 71 can only approach each other but cannot move away from each other, avoiding the two positioning arc plates 71 moving away from each other due to vibration in the subsequent movement process, and improving the positioning precision.

[0028] After the tool 6 loaded with the knob base is moved to the lower side of the feeding manipulator 3 under the action of the precision divider, the knob spring, the knob shaft sleeve and the knob torsion piece are inserted and pressed onto the knob base in sequence under the action of the feeding manipulator 3. The feeding manipulator 3 adopts a SCARA robot (selective compliance assembly robot arm). This kind of manipulator arm can quickly take and place in the plane and vertically press. The multiple feeding manipulators 3 above the base 1 correspondingly grab the knob base, the knob spring, the knob shaft sleeve and the knob torsion piece below. The knob base is grabbed and placed into the tool 6 by the corresponding feeding manipulator 3 and is clamped and fixed by the positioning structure 7. Then the tool moves to the left rear side. The feeding manipulator 3 at this position grabs the knob spring and places it into the notch of the knob base. Then the tool 6 moves to the right rear side again. The feeding manipulator 3 at this position grabs the knob shaft sleeve and presses it downward to the notch on the knob base to be connected in interference fit. The knob spring is in the aperture between the knob shaft sleeve and the knob base. Finally, the tool 6 moves to the right front side. The feeding manipulator 3 at this position grabs the knob torsion piece and inserts it into the knob shaft sleeve in interference fit, completing the entire assembly. After the tool 6 loaded with the complete knob workpiece moves to the lower side of the discharging manipulator 4, the tool 6 will contact the expansion plate 11 below the discharging manipulator 4. When the tool 6 approaches the expansion plate 11, the moving wheel 812 will first contact one of the unlocking inclined surfaces 14. The moving wheel 812 will move from the upper surface of the rack 1 to the upper side of the extension bottom plate 13 through the unlocking inclined surface 14. At this time, the lifting rod 81 is upward as a whole, and the bottom end of the limiting head 82 is above the limiting groove 732, thereby releasing the limiting of the driving frame 73. At this time, the driving frame 73 can move freely. After the moving wheel 812 moves to the upper side of the extension bottom plate 13 along the unlocking inclined surface 14, the driving wheel 76 will contact the expansion inclined surface 12 of the expansion plate 11 and move to the straight plate of the expansion plate 11 through the expansion inclined surface 12. Since the distance between the expansion inclined surface 12 close to the straight plate and the tool 6 is greater than the distance between the expansion inclined surface 12 away from the straight plate and the tool 6, the driving frame 73 will move outward away from the tool 6 under the action of the driving wheel 76, thereby pressing the clamping rollers 721 to move the two clamping rollers 721 away from the tool 6. The two positioning arc plates 71 will move away from each other, and there is a certain distance between the positioning arc plate 71 and the outer surface of the knob workpiece. At this time, the discharging manipulator 4 can grab the knob workpiece to make it be discharged from the tool 6.

[0029] The above operation is repeated, so that the tool 6 can continuously move to the lower side of the four feeding manipulators 3 to feed one by one and move to the lower side of the discharging manipulator 4 to discharge.

[0030] By setting the moving track 5 of the rectangular structure above the rack 1, a plurality of jigs 6 are slid above the moving track 5 and are distributed at equal intervals, and the plurality of jigs 6 are sequentially passed through the plurality of feeding mechanical arms 3 and the discharging mechanical arm 4, so that the plurality of accessories in the knob are sequentially assembled and discharged in order, and the assembly efficiency is improved. By setting the placing groove 61 on the jig 6, and the inner diameter of the placing groove 61 is greater than the outer diameter of the knob base, so that the knob base is placed without contacting the inner wall of the placing groove 61, avoiding abrasion caused by contacting the inner wall of the placing groove 61, and the positioning structure 7 arranged on the jig 6 can clamp and position the knob base, and ensure that the knob base is at the center of the placing groove 61, improve the positioning accuracy, and ensure the assembly accuracy. By setting the limiting structure 8 on the jig 6, placing the knob base in the jig 6, and clamping and positioning the knob base by the positioning structure 7, the limiting structure 8 can limit the positioning structure 7, so that the positioning arc plate 71 in the positioning structure 7 cannot be separated from the knob base, avoiding the two positioning arc plates 71 from moving away from each other due to vibration in the subsequent movement process, and improving the positioning accuracy.
