Description

Technical Field

[0001] This invention relates to the field of drilling equipment, specifically a feather racket positioning drilling device. Background Technology

[0002] Existing badminton racket drilling equipment has evolved from manual positioning drilling to automatic positioning drilling. In this system, after the machine head clamps the racket frame through the racket clamp, it automatically rotates the racket frame under the drill bit to drill around the racket frame, thereby reducing the risks and low accuracy of manual drilling and positioning operations.

[0003] However, in existing technologies, badminton rackets are usually fed manually. The machine head moves to a position near the outer side of the frame, and the racket frame is placed on the racket clamp by hand. Some machines use a crossbar to suspend several racket frames, and then a robotic arm pulls the racket frames from the end of the crossbar and transports them to the racket clamp. However, due to the limited range of movement of the robotic arm, the crossbar is located on the inner side of the frame near the machine head, far from the outer side of the frame, and there is only one fixed feeding position. This makes it difficult to replenish the material manually. Often, the machine can only be stopped and the material replenished manually after the last racket frame has been processed. This makes the process inconvenient. Furthermore, manually placing rackets during the machine's operation intervals poses a significant safety hazard. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a badminton racket positioning drilling device, comprising a frame, a clamping head mounted inside the frame, a drilling head, and a feeding assembly mounted on the edge of the frame. A transfer assembly is provided at the top of the frame between the feeding assembly and the clamping head. The feeding assembly includes two sets of alternately operating feeding shafts, the top of which is used to suspend the racket frame. The two sets of feeding shafts are respectively located near the inside and outside of the frame, with the horizontal height of the feeding shaft near the outside of the frame lower than that of the other feeding shaft. The feeding assembly also includes a base and a swing arm component oscillatingly connected to the base. The arm component includes a front swing arm and a rear swing arm. The delivery shaft is fixed on the front swing arm and the rear swing arm respectively. A synchronous switching mechanism is fixedly installed on the base to drive the front swing arm and the rear swing arm to swing alternately. The delivery shaft includes a long beam fixed on the swing arm component, a storage shell mounted on the long beam, and a conveyor belt. The conveyor belt is used to carry the racket frame near the inner side of the frame and drive the racket frame to move. The storage shell and the conveyor belt are independently located at the top to carry the racket frame and are switched by the swing of the swing arm component. The swing of the swing arm component causes the storage shell or the conveyor belt to face the top of the delivery shaft individually.

[0005] Furthermore, the storage case includes a cylindrical annular side surface, and the storage case swings by a swing arm component to allow the smooth surface to be independently located at the top of the delivery shaft for supporting the racket frame; the conveyor belt has a straight section located outside the long beam for conveying the racket frame, and the storage case moves away from the conveyor belt to allow the conveyor belt to be independently located at the top of the delivery shaft, and allows the racket frame to be transferred from the storage case to the conveyor belt.

[0006] Furthermore, the rear end of the rear swing arm is provided with a back plate, and the rear swing arm and the back plate are slidably connected by a clearance slide rail. The back plate and the base are oscillatingly connected. A display guide frame is fixedly installed on the base. The display guide frame has an arc-shaped co-position annular groove and a display annular groove from top to bottom. A synchronous wheel is rotatably installed on the rear swing arm. The synchronous wheel moves within the co-position annular groove and the display annular groove.

[0007] Furthermore, the radius of the booth annular groove is larger than that of the corresponding annular groove, and the booth annular groove and the corresponding annular groove are connected by a transition groove. The difference between the radius of the booth annular groove and the radius of the corresponding annular groove is greater than the diameter of the storage shell. The arc of the corresponding annular groove is less than 35 degrees.

[0008] Furthermore, the root of the long beam is fixed to the swing arm component, and conveyor wheels are rotatably mounted at both the end and root of the long beam. A conveyor motor is fixedly mounted at the root of the long beam and is connected to the conveyor wheels for transmission. The conveyor belt is wound between the two conveyor wheels. The middle of the storage shell has a groove and is movably nested in the side of the long beam without a conveyor belt through the groove. A switching mechanism is movably mounted on the swing arm component and abuts against the storage shell. The storage shell is displaced near the inner side of the frame by the switching mechanism so that the conveyor belt is independently located at the top of the delivery shaft.

[0009] Furthermore, a forward-extending platform is fixed to the bottom of the front end of the swing arm component, and a top sliding groove is provided at the front end of the front extension platform. The switching mechanism includes a top block that is movably engaged in the top sliding groove. A receiving step block is fixed to the side of the storage shell near the switching mechanism. The head edges of the top block and the head edges of the receiving step block are both inclined. The receiving step block disengages from the top block, causing the storage shell to move away from the conveyor belt. The switching mechanism also includes a counterweight assembly for driving the top block to move within the top sliding groove. An inclined moving groove is provided in the storage shell. A fixed wheel is rotatably mounted on the side of the long beam. The fixed wheel is slidably engaged in the inclined moving groove. The distance between the bottom end of the inclined moving groove and the swing arm component is less than the distance between the top end of the inclined moving groove and the swing arm component. The storage shell that disengages from the top block moves downward through the inclined moving groove.

[0010] Furthermore, the counterweight assembly is rotatably mounted on the swing arm component, the swing axis of the counterweight assembly is parallel to the length direction of the long beam and located inside the long beam, and the counterweight assembly rotates relative to the long beam as the swing arm component swings; a buckle is fixed on the counterweight assembly, and a driven frame is fixed on the top block, the buckle being used to drive the driven frame to move.

[0011] Furthermore, a spring is connected between the top block and the swing arm component. One end of the spring is fixed to the center line of the swing arm component, while the other end is fixedly connected to the top block. The spring provides a spring force to the top block located in the middle of the top sliding groove, pointing towards the storage shell. The spring also provides a spring force to the top block located on one side of the top sliding groove, causing the top block to move towards the end of the top sliding groove.

[0012] Furthermore, the synchronous shifting mechanism includes a driving gear, a driven gear, and a shifting motor. The driving gear is rotatably connected to the base, the shifting motor is fixed to the base and connected to the driving gear, the driven gear is fixed to the swing arm component, and the axis of the driven gear is collinear with the axis of the swing arm component rotatably connected to the base. The driven gears on both sides mesh with the driving gear in the middle.

[0013] Furthermore, the transfer assembly includes a movable seat, a swing motor is fixed to the side of the movable seat, the shaft of the swing motor is connected to a gripper cylinder and drives the gripper cylinder to swing, the gripper cylinder is fixed with a side claw for gripping the racket frame; swinging the side claw causes the racket frame to swing upward, the projection of the bottom of the racket frame on the horizontal plane and the projection of the end of the long beam on the horizontal plane are spaced apart; a lifting cylinder is connected to the movable seat for driving the movable seat to move up and down, the lifting cylinder is fixedly connected to the translation mechanism.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This invention features two sets of feeding shafts for carrying and transporting racket frames. Two sets of alternating swing arms allow the two feeding shafts to move alternately. When one feeding shaft is carrying and transporting a racket frame inside the frame, the other feeding shaft can be positioned near the outside of the frame for convenient loading by the user. After the inner feeding shaft is empty, a synchronous switching mechanism drives the two swing arms to move alternately, sending the feeding shaft now carrying a new racket frame to the inside of the frame for feeding. This achieves continuous, cyclical feeding without stopping the machine, while also preventing the user from entering the processing area inside the frame to feed, reducing safety hazards.

Detailed Implementation

[0023] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Examples, such as Figures 1-7 As shown: This invention provides a badminton racket positioning drilling device, including a frame 1, a clamping head 2 installed inside the frame 1, a drilling head 4, and a translation mechanism, as well as a feeding assembly 6 installed on the edge of the frame 1. The translation mechanism includes a first translation mechanism 7 and a second translation mechanism 8. The clamping head 2 is movably mounted inside the frame 1 through two sets of first translation mechanisms 7. The two sets of first translation mechanisms 7 form an XY worktable as in the prior art, thereby allowing the clamping head 2 to obtain the freedom of movement of the X-axis and Y-axis in the horizontal direction within the frame 1. The X-axis or Y-axis formed by the first translation mechanism 7 is rotated by a lead screw driven by a motor. This causes the seat connected to the lead screw via the lead screw nut to translate along the axis of the lead screw. The clamping head 2 has a racket clamp 3 for clamping the racket frame A, which consists of two plates that conform to the inner contour of the racket frame A, driven by a cylinder. The racket frame A has an approximately elliptical frame and a straight handle at the bottom of the frame. The racket clamp 3 is used to clamp the approximately elliptical frame. When the racket frame A is placed on the racket clamp 3, the cylinder works to open the two plates, supporting the inner side of the racket frame A. Then, the drilling head 4 moves up and down in the vertical direction to drill holes in the racket frame A.

[0025] A transfer assembly 5 is provided at the top of the frame 1 between the feeding assembly 6 and the clamping head 2. The transfer assembly 5 is movably mounted in the frame 1 via the second translation mechanism 8. The transfer assembly 5 includes a movable seat 54, and a swing motor 53 is fixed to the side of the movable seat 54. The shaft 531 of the swing motor 53 is connected to a gripper cylinder 51 and drives the gripper cylinder 51 to swing. A pair of side claws 52 are fixed on the gripper cylinder 51 for gripping the racket frame A. The gripper cylinder 51 is an existing gripper cylinder 51 with a pair of mutually movable push blocks. The two side claws 52 are respectively fixed on the two push blocks, so that they are opened and closed by the gripper cylinder 51. A lifting cylinder 55 is connected to the movable seat 54 for driving the movable seat 54 to move up and down. The lifting cylinder 55 is fixed to the second translation mechanism 8. The connection is driven by the second translation mechanism 8 to move. The second translation mechanism 8 includes a transverse beam seat 82, synchronous pulleys 84 rotatably mounted on both sides of the beam seat 82, and a synchronous belt 83 wound around the two synchronous pulleys 84. A synchronous motor 85 is also fixedly mounted on the beam seat 82. The synchronous motor 85 is fixedly connected to a synchronous pulley 84 to drive the synchronous pulley 84 to rotate. A belt drive mechanism is formed by the synchronous pulley 84 and the synchronous belt 83. At this time, a slide block 81 is slidably mounted on the beam seat 82, and then the slide block 81 is fixedly connected to the synchronous belt 83. When the synchronous belt 83 moves, it drives the slide block 81 to translate, so that the side claw 52 moves between the feeding assembly 6 and the clamping head 2 to move the racket frame A on the feeding assembly 6 to the clamping head 2. It should be noted that when picking up material from the feeding assembly 6, the rotation of the swing motor 53 causes the side claw 52 to swing the racket frame A upward. The projection of the bottom of the racket frame A on the horizontal plane is separated from the projection of the end of the long beam 611 on the horizontal plane, thus avoiding the feeding assembly 6 in the lateral direction.

[0026] The feeding assembly 6 includes two sets of alternately operating feeding shafts 61. The top of the feeding shafts 61 is used to suspend the racket frame A. The two sets of feeding shafts 61 are located near the inner side of the frame 1 and near the outer side of the frame 1, respectively. They move from the outer side of the frame 1 to the inner side of the frame 1 and from the inner side of the frame 1 to the outer side of the frame 1 through reciprocating alternating motion. The horizontal height of the feeding shaft 61 near the outer side of the frame 1 is lower than that of the other feeding shaft 61. The lower outer feeding shaft 61 is used for pre-feeding, and the higher inner feeding shaft 61 is used for transferring the transfer assembly 5. During the alternating motion, specifically, the feeding assembly 6 also includes a base 62 and a swing arm component oscillatingly connected to the base 62. The swing arm component includes a front swing arm 63 and a rear swing arm 64. The feeding shaft 61 is fixedly fixed to the front swing arm 63 and the rear swing arm 64 respectively. The front swing arm 63 and the rear swing arm 64 are rotatably connected to the base 62 via a gear fixed shaft 621, and the rotation axes of the front swing arm 63 and the rear swing arm 64 are collinear. In this embodiment, the front swing arm 63 and the rear swing arm 64 rotate to a vertical state and a horizontal state respectively within a 90-degree rotation range. In order to drive the front swing arm 63 and the rear swing arm 64 to swing alternately, a synchronous shifting mechanism 65 is fixedly installed on the base 62 to drive the front swing arm 63 and the rear swing arm 64 to swing alternately. The synchronous shifting mechanism 65 includes... The system includes a drive gear 651, a driven gear 653, and a shifting motor 652. The drive gear 651 is rotatably connected to the base 62. The shifting motor 652 is fixed to the base 62 and connected to the drive gear 651. The driven gear 653 is fixed to the swing arm component. The axis of the driven gear 653 is collinear with the axis of the swing arm component rotatably connected to the base 62. The driven gears 653 on both sides mesh with the drive gear 651 in the middle. The rotation of the drive gear 651 in the middle drives the driven gears 653 on both sides to rotate, so that the front swing arm 63 and the rear swing arm 64 alternate between vertical and horizontal states. This allows one delivery shaft 61 to supply racket frame A to the transfer assembly 5 on the inside, while the other delivery shaft 61 allows the worker to pre-place and suspend racket frame A on the outside. It should be noted that the rear end of the rear swing arm 64 is provided with a back plate 641. The rear swing arm 64 and the back plate 641 are slidably connected by a clearance slide rail 642. A positioning seat 643 is fixed on the back plate 641 to abut against the bottom of the rear swing arm 64, thereby limiting the position of the rear swing arm 64. The back plate 641 and the base 62 are oscillatingly connected, that is, the rear swing arm 64 can slide in the length direction of the rear swing arm 64 and the back plate 641, which means that the rear swing arm 64 and the placement on the rear swing arm 64 are... The shaft 61 can move away from the base 62, so that when the two delivery shafts 61 approach each other, the delivery shaft 61 of the rear swing arm 64 can avoid the delivery shaft 61 of the front swing arm 63. For this purpose, a display guide frame 67 is fixedly installed on the base 62. The display guide frame 67 has an arc-shaped co-position annular groove 671 and a display annular groove 672 from top to bottom. A synchronous wheel 66 is rotatably installed on the rear swing arm 64. The synchronous wheel 66 moves within the co-position annular groove 671 and the display annular groove 672. The radius of the display ring groove 672 is larger than that of the corresponding ring groove 671. The display ring groove 672 and the corresponding ring groove 671 are connected by a transition groove 673. The difference between the radius of the display ring groove 672 and the radius of the corresponding ring groove 671 is greater than the diameter of the storage shell 615. More specifically, it is greater than the sum of the diameter of the storage shell 615 and the thickness of the racket frame A. In this embodiment, it is set to be greater than 1.5 times the diameter of the storage shell 615. At the same time, the arc of the corresponding ring groove 671 is less than 35 degrees, thereby allowing the placement shaft 61 of the rear swing arm 64 to move outward in advance and move to the rear swing arm on the display ring groove 672. Arm 64 then moves the placement shaft 61 away from the base 62. Thus, when it approaches the placement shaft 61 of the front swing arm 63, the placement shaft 61 on the rear swing arm 64 avoids it. It should be noted that when the racket frame A, which is suspended on the placement shaft 61 of the rear swing arm 64, moves closer to the placement shaft 61 of the front swing arm 63, the placement shaft 61 of the front swing arm 63 pushes against the racket frame A, causing the racket frame A to swing on the placement shaft 61 of the rear swing arm 64, until the placement shaft 61 of the front swing arm 63 moves below the placement shaft 61 of the rear swing arm 64, until the bottom of the racket frame A is no longer in contact with the placement shaft 61 of the rear swing arm 64.

[0027] In this embodiment, a feeding suspension area is provided on the feeding shaft 61. Since the feeding shaft 61 of the rear swing arm 64 is slightly longer than that of the front swing arm 63, the feeding suspension area is set to a fixed length extending from the inner side of the end of the feeding shaft 61 towards the root. This length extends to the root of the shorter feeding shaft 61. The racket frame A is suspended in the feeding suspension area. A limiting stop 11 and a merging guide 12 are fixed side by side below the feeding shaft 61 near the inner side of the frame 1. The length of the merging guide 12 is less than the length of the limiting stop 11, and the head of the merging guide 12 is outwardly extended. A gap is formed between the stop frame 11 and the combined guide frame 12 to allow the racket handle of the racket frame A to pass through, thereby determining the middle position of the racket frame A. There is a gap between the projection of the loading suspension area on the horizontal plane and the projection of the combined guide frame 12 on the horizontal plane, so that when the feeding shaft 61 approaches the stop frame 11, the racket handle will not hit the combined guide frame 12. Furthermore, the surface of the stop frame 11 is covered with shock-absorbing and energy-absorbing materials such as foam and rubber. When the racket frame A on the feeding shaft 61 of the rear swing arm 64 disengages from the feeding shaft 61 of the front swing arm 63 and swings downward, it will fall onto the stop frame 11.

[0028] When suspending racket frame A, specifically, the placement shaft 61 includes a long beam 611 fixed to the swing arm component, a storage casing 615 mounted on the long beam 611, and a conveyor belt 613. The conveyor belt 613 carries the racket frame A near the inner side of the frame 1 and moves the racket frame A, transporting the racket frame A to the end of the long beam 611. A baffle is fixed to the end of the long beam 611. The racket frame A, when moved there, rests against the baffle, and the side claw 52 is automatically aligned with the position in front of the baffle for gripping. Therefore, the baffle positions the racket frame. The base position for material handling is that the storage shell 615 and the conveyor belt 613 are independently located at the top to support the racket frame A and are switched by the swing of the swing arm component. The swing of the swing arm component causes the storage shell 615 or the conveyor belt 613 to face the top of the feeding shaft 61. When the swing is in a horizontal state, the storage shell 615 is independently located at the top to support the racket frame A. When the swing is in a vertical state, the displacement of the storage shell 615 exposes the conveyor belt 613, which is then independently located at the top to support the racket frame A. The swing arm component has a through-beam groove 6a, through which a long beam 611 passes. The long beam 611 is detachably fixed to the swing arm component at the rear of the swing arm component via a beam bracket 616 and bolts, so that the root of the long beam 611 is fixed to the back of the swing arm component. Both the end and the root of the long beam 611 are rotatably equipped with conveyor wheels 612. The root of the long beam 611 is fixedly installed on the back of the swing arm component with a conveyor motor 614, and the conveyor motor 614 is connected to the conveyor wheels 612 for transmission. The conveyor motor 614 can also be used as a counterweight for the long beam 611. The conveyor belt 613 is wound between the two conveyor wheels 612, and the conveyor belt 613 and the conveyor wheels 612 also form a pulley mechanism. The conveyor belt 613 has a straight section located outside the long beam 611 for conveying the racket frame A. The conveyor belt 613 is made of rubber, thereby driving the racket frame A to move. In this embodiment, the top and bottom of the long beam 611 have long grooves that are recessed into the interior of the long beam 611. The long grooves have vertical inner extension walls 6111 on both sides, which provide vertical support for the long beam 611. A sliding rail 6112 is nested in the long groove at the top. The top surface of the sliding rail 6112 is smooth, which is used to allow the conveyor belt 613 to slide on the sliding rail 6112 and to support the conveyor belt 613, preventing the conveyor belt 613 carrying the racket frame A from sagging.

[0029] The storage casing 615 has a central groove 615b and is movably nested within the side of the long beam 611 without the conveyor belt 613. The storage casing 615 includes a main casing 6151 and side casing blocks 6152. The side casing blocks 6152 are detachably fixed to the main casing 6151 by bolts. The main casing 6151 and the side casing blocks 6152 are assembled to form the groove 615b. The storage casing 615 includes a cylindrical, annular, smooth surface 615a located outside the main casing 6151. The main casing 6151 and the side casing blocks 6152 can be made of perforated plastic, while the smooth surface 615a is formed by covering with a metal sheet, thus ensuring a smooth surface while reducing weight. The projection of the storage casing 615 onto a plane perpendicular to the long beam 611 has an arc-shaped edge, i.e., the main casing 6151 and the side casing blocks 6152... The arc formed by the edge of the package 6152 is part of a circular structure and can extend to form a complete circular range at both edges of the arc. When the package 615 does not move away from the long beam 611, the projection of the conveyor belt 613 on the plane perpendicular to the long beam 611 is located within the circular range formed by the extension of the arc-shaped edge. The package 615 swings to a horizontal state through the swing arm member, so that the smooth surface 615a is independently located on the top of the delivery shaft 61 to support the racket frame A. The package 615 moves away from the conveyor belt 613, so that the conveyor belt 613 is independently located on the top of the delivery shaft 61. That is, after the swing arm member drives the delivery shaft 61 to a vertical state, the package 615 descends, exposing the conveyor belt 613 upwards, and the racket frame A is transferred from the package 615 to the conveyor belt 613.

[0030] Therefore, a switching mechanism 68 is movably mounted on the swing arm component to abut against the storage shell 615. The storage shell 615, located near the inner side of the frame 1, is displaced away from the long beam 611 via the switching mechanism 68, thus allowing the conveyor belt 613 to be independently positioned on top of the delivery shaft 61. When the swing arm component moves the delivery shaft 61 to a horizontal position, the switching mechanism 68 moves the storage shell 615 towards the long beam 611, allowing the horizontal delivery shaft 61 to bear load on the smooth surface 615a. After racket frame A is in place, until the swing arm component drives the feeding shaft 61 to swing to a vertical state, racket frame A can make good contact with the smooth surface 615a or the edge of the smooth surface 615a. This ensures that racket frame A slides well on the smooth surface 615a, keeping the handle in a downward position. Instead of directly contacting the conveyor belt 613 when it is about to reach a vertical state, racket frame A would be blocked by the conveyor belt 613 and unable to slide well, causing racket frame A to tilt on the conveyor belt 613. Specifically, a forward-extending platform 6b is fixed to the bottom of the front end of the swing arm component. The top of the platform 6b contacts the long beam 611 and serves as an auxiliary support structure for the long beam 611. The front end of the platform 6b extends downward and has a top sliding groove 6c. The switching mechanism 68 includes a top block 681 that is movably engaged in the top sliding groove 6c. The switching mechanism 68 also includes a counterweight assembly 684 for moving the top block 681 within the top sliding groove 6c. A receiving step 6153 is fixed to the side of the storage shell 615 near the switching mechanism 68. The head edges of both the top block 681 and the receiving step 6153 are inclined. The top block 681 contacts the receiving step 6153, thereby moving the receiving step 6153 and the receiving step 6153. The storage shell 615 moves closer to the long beam 611. The top step 6153 disengages from the top block 681, causing the storage shell 615 to move away from the long beam 611 and the conveyor belt 613. The storage shell 615 has a slanted groove 615c in its groove 615b. The long beam 611 has a fixed wheel 6113 rotatably mounted on its side. The fixed wheel 6113 slides and engages in the slanted groove 615c. The distance between the bottom of the slanted groove 615c and the swing arm component is smaller than the distance between the top of the slanted groove 615c and the swing arm component. The storage shell 615, which disengages from the top block 681, moves downward and diagonally downward through the slanted groove 615c, and moves upward and diagonally upward through the top block 681. In this embodiment, the counterweight assembly 684 is a counterweight block. The top of the counterweight assembly 684 has a buckle structure. A circular ring platform 6d is provided on the swing arm component at the root of the front extension platform 6b. A bearing is nested on the ring platform 6d. The counterweight assembly 684 is nested on the bearing and thus rotatably mounted on the swing arm component. The swing axis of the counterweight assembly 684 is parallel to the length direction of the long beam 611 and located within the long beam 611. The counterweight assembly 684 rotates relative to the long beam 611 following the swing of the swing arm component. A buckle 685 is fixed on the counterweight component 684. The buckle 685 has structural walls on both sides, making it U-shaped when viewed from above. A driven frame 683 is fixed on the top block 681. The driven frame 683 is located inside the buckle 685. The buckle 685 is used to drive the driven frame 683 to move. When the swing arm component swings, the counterweight component 684 hangs down due to gravity, thereby changing the position of the slider on the swing arm component. The top block 681 moves by the buckle 685 engaging the driven frame 683. Furthermore, in this embodiment, a spring 682 is connected between the top block 681 and the swing arm component. One end of the spring 682 is fixed to the centerline of the swing arm component, while the other end is fixedly connected to the top block 681. The spring 682 provides a spring force to the top block 681 located in the middle of the top slide groove 6c, pointing towards the storage shell 615. The spring 682 also provides a spring force to the top block 681 located on one side of the top slide groove 6c, causing the top block 681 to move towards the end of the top slide groove 6c. Thus, the spring 682 has only two states within the top slide groove 6c, namely, the state in which it is stably located at both ends of the top slide groove 6c under the influence of the spring 682. It should be noted that the side wall of the buckle 685 that drives the driven frame 683 and the top block 681 to move away from the top step block 6153 is located in the middle of the counterweight assembly 684. When the spring 682 provides a spring force to the top block 681, which is located in the middle of the top sliding groove 6c, pointing towards the storage shell 615, the side wall of the buckle 685 contacts the driven frame 683. At this time, the swing arm component has not yet fully swung to the vertical state. That is, when the swing arm component continues to swing to the vertical state, the buckle 685... 85 can continue to move the driven frame 683 and the top block 681 a certain distance. At this time, the spring 682 will shift from the middle to one side, and instantly apply a spring force to the top block 681 to move towards the side of the top sliding groove 6c, so that the top block 681 can quickly break away from the contact with the top step 6153. This allows the top block 681 and the top step 6153 to maintain sufficient contact and abutment before the swing arm component swings completely to the vertical state, thus making the storage shell 615 more stable.

[0031] In summary, during implementation, the front swing arm 63 is initially positioned near the outer side of the frame 1. The synchronous shifting mechanism 65 drives the front swing arm 63 to swing to a horizontal position, while the rear swing arm 64 remains vertical. Workers place several racket frame pieces A in the loading suspension area of ​​the feeding shaft 61. At this time, the feeding shaft 61 supports the racket frame A via the smooth surface 615a of the storage casing 615. Then, the synchronous shifting mechanism 65 is activated, causing the front swing arm 63 to swing vertically. During this swing, the racket frame piece A slides on the smooth surface 615a, keeping the handle at the bottom of the racket frame piece A always downward. Simultaneously, the counterweight assembly 684 also remains downward due to its weight, causing the buckle 685 on the counterweight assembly 684 to engage the driven frame 683, thereby lifting the top... Block 681 begins to move, moving the top block 681 away from the top step block 6153. When the front swing arm 63 swings to the vertical position, the spring 682 shifts from the middle to one side, instantly applying a spring force to the top block 681 to move towards the top sliding groove 6c, thereby causing the top block 681 to quickly detach from the top step block 6153. This allows the storage shell 615 to slide and engage with the fixed wheel 6113 through the inclined groove 615c, thus moving diagonally downwards. This exposes the top conveyor belt 613, and the racket frame A on the storage shell 615 falls onto the conveyor belt 613. Driven by the conveyor belt 613, it moves towards the baffle at the end of the long beam 611. The racket frame A is stably conveyed below by the limiting baffle 11 and the guiding frame 12. During the vertical swing of the front swing arm 63, the synchronous wheel 66 on the rear swing arm 64 moves from the same position ring groove 671 to the extension ring groove 672. The rear swing arm 64, which moves to the extension ring groove 672, moves away from the base 62 with the delivery shaft 61. Thus, when it approaches the delivery shaft 61 of the front swing arm 63, the delivery shaft 61 on the rear swing arm 64 avoids it. After the racket frame A, placed on the feed shaft 61 on the front swing arm 63, is conveyed by the conveyor belt 613 and hits the baffle, as those skilled in the art will know, infrared sensors can be set around the baffle to detect that the racket frame A has reached the designated position. The gripper cylinder 51 drives the side gripper 52 to open, and the second translation mechanism 8 drives the lifting cylinder 55 to move above the racket frame A. The lifting cylinder 55 descends, causing the side gripper 52 to move onto the racket frame A. Then, the gripper cylinder 51 drives the side gripper 52 to retract, clamping the racket frame A. Subsequently, the lifting cylinder 55 rises slightly. However, if it continues to rise, the lower part of the racket frame A will be subjected to the feed shaft 61. Unable to rise further due to limitations, after rising a short distance, the swing motor 53 rotates, causing the side claw 52 to swing the racket frame A upward, thus dislocating the racket frame A from the feeding shaft 61. This allows the racket frame A to avoid the feeding assembly 6 laterally when the second translation mechanism 8 drives the lifting cylinder 55 to move horizontally, and move to the racket clamp 3 on the clamping head 2. Then, the swing motor 53 rotates, causing the racket frame A to swing downward to vertical, allowing the racket frame A to be clipped onto the racket clamp 3 and held in place. The drilling head 4 then performs drilling as is done in the prior art. After drilling is completed, the racket is unloaded manually or by a robotic arm. At this time, the feed shaft 61 of the rear swing arm 64 is positioned near the outside of the frame 1. Workers can suspend several racket frames A in the loading suspension area of ​​the feed shaft 61. After the racket frames A on the feed shaft 61 of the front swing arm 63 are used up, the rear swing arm 64 can be swung upwards for quick handover. When the racket frames A suspended on the feed shaft 61 of the rear swing arm 64 move closer to the feed shaft 61 of the front swing arm 63... The feed shaft 61 of the front swing arm 63 pushes against the racket frame A, causing the racket frame A to swing on the feed shaft 61 of the rear swing arm 64 until the feed shaft 61 of the front swing arm 63 moves below the feed shaft 61 of the rear swing arm 64, and at the same time until the racket handle at the bottom of the racket frame A is no longer in contact with the feed shaft 61 of the rear swing arm 64, the racket frame A naturally hangs down and rests against the limit stop 11, waiting for the conveyor belt 613 to deliver it.
