A badminton racket molding production line

Abstract

This invention relates to the field of drilling equipment, specifically a badminton racket forming production line. The structure includes a frame, a conveyor belt, a main head, a drilling mechanism, and a feeding assembly. The feeding assembly includes a slant bar with a shifting component mounted on it. The frame includes a crossbar, and the shifting component includes a curved fork arm. The middle of the curved fork arm rotates on the slant bar, and both sides of the curved fork arm have arm-like structures for pushing the racket frame on the slant bar and for engaging with the crossbar. The conveyor line of this invention uses a slant bar at the front end of the drilling process to receive the racket frame. The slant bar is then engaged with the crossbar of the frame by several shifting components, allowing it to suspend on the frame. The head of the slant bar can continuously suspend the racket frame. By sequentially driving the shifting components to rotate, the racket frame at the head of the slant bar is automatically conveyed step-by-step to the tail end for the transport mechanism to clamp onto the main head for mounting. This overcomes the limitation of existing feeding crossbars where feeding and discharging are at the same end, making replenishment difficult.

Description

Technical Field

[0001] This invention relates to the field of drilling equipment, specifically a badminton racket forming production line. Background Technology

[0002] Existing badminton racket production lines are gradually transitioning from manual to automated processes. Due to the limitations of racket frame shape, some operations, such as pressing the racket ring and shaft, demolding and impurity removal, are still performed manually. However, the conveying steps and drilling operations are now carried out by automated equipment. For example, the current drilling operation uses automatic positioning drilling equipment. After the main head clamps the racket frame through the racket clamp, it uses a translation mechanism to drive the drill bit to rise and fall to drill holes in the racket frame. The main head also rotates to make the drill bit drill around the racket frame.

[0003] In the existing feeding methods of equipment, some equipment uses a crossbar inside the frame to suspend several racket frames. Then, the racket frames are pulled away from the end of the crossbar by the clamping and placing mechanism on the frame and transferred to the racket clamp. In this form, the crossbar is relatively close to the inside of the equipment, and there is only one position for feeding the crossbar, that is, the end of the crossbar. Because the root of the crossbar needs to be fixed to the support structure to support the crossbar, it is difficult to replenish the material manually. If the rackets are placed manually during the equipment operation interval, there will be a significant safety hazard. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a badminton racket forming production line. The structure includes a frame, a conveyor belt disposed at the first end of the frame, a main machine head disposed at the second end of the frame, and a drilling mechanism. A feeding assembly and a conveying mechanism are fixedly disposed between the conveyor belt and the main machine head. The main machine head is used to clamp the racket frame, the drilling mechanism is used to drill holes in the racket frame on the main machine head, the feeding assembly is used to continuously supply racket frames to the main machine head without switching the feeding structure, and the conveying mechanism is used to feed the feeding assembly, transport the racket frame from the feeding assembly to the main machine head, and unload the racket frame from the main machine head.

[0005] The feeding assembly includes a slanted rod for suspending the racket frame. The slanted rod is inclined, with its first end higher than its last end. The top surface of the slanted rod has a sliding surface for the suspended racket frame to slide downwards along the inclined surface. The last end of the slanted rod has a horizontal flat bearing section. The conveying mechanism includes a gripper cylinder that moves on the frame and grippers mounted on the gripper cylinder, used to move the racket frame inwards towards the first end of the slanted rod and outwards towards the last end of the slanted rod. At least three drive components and a shifting component are mounted on the slanted rod. The frame includes a horizontal... The crossbar includes a shifting assembly for shifting rotation and engaging with the crossbar. The diagonal bar is engaged with the crossbar via at least two shifting assemblies, suspending the diagonal bar below the crossbar. Each shifting assembly includes a curved fork arm, the middle of which is rotatably mounted on the diagonal bar. The curved fork arm has arm-like structures on both sides of its middle portion, which are used to push the racket frame on the diagonal bar and to engage with the crossbar. One arm-like structure of the curved fork arm near the head of the diagonal bar has a limiting plate fixed on the side away from the opposite arm-like structure. The outer edge of the limiting plate is arc-shaped.

[0006] Furthermore, the drive assembly is fixed to the bottom of the slant bar, and the drive assembly includes a double-headed drive shaft. The shifting assembly has two bent fork arms, with the middle fixed to the drive shaft. The inner side of the arm-shaped structure that swings from the head to the tail of the slant bar forms a pushing structure on the slant bar to push the racket frame on the slant bar. The inner side of the bent fork arm is provided with a smoothing component to form an arc-shaped support for the racket frame pushed by the arm-shaped structure. The end of the arm-shaped structure is provided with a protruding push head, and the inner side of the push head is provided with a recessed engagement groove. The crossbar includes a top mounting surface and a bottom support surface. The engagement groove is clearance-fitted with the crossbar. The arm-shaped structure that engages with the crossbar forms a blocking structure in the vertical direction to block the racket frame on the slant bar.

[0007] Furthermore, the first and last ends of the diagonal bar have stationary spaces for suspending the frame. The two ends of the two stationary spaces are the edge of the diagonal bar and the edge of the range of motion of the end of the curved fork arm adjacent to the edge, respectively. The length of the stationary space is greater than the length of the arm-like structure of the curved fork arm.

[0008] Furthermore, the angle between the inclined bar and the horizontal plane ranges from 6° to 10°, and the two arm-like structures of the curved fork arm have an angle between them, which ranges from 90° to 105°; the sliding surface at the top of the inclined bar is raised from both sides to the middle, the racket frame suspended on the sliding surface contacts the middle of the sliding surface, and the horizontal height of the end of the arm-like structure that tends to form the blocking structure is lower than the horizontal height of the sides of the sliding surface.

[0009] Furthermore, the curved fork arm has a basic state, in which the inner sides of several curved fork arms all point towards the head end of the diagonal bar and the curved fork arms are engaged with the crossbar. The limiting meniscus is fixed on the arm-shaped structure in the basic state and has a tendency to form a pushing structure. The radius of the outer edge of the arc-shaped limiting meniscus is equal to the length of the arm-shaped structure, and the degree measure of the central angle of the outer edge of the limiting meniscus is greater than the degree measure of the angle between the diagonal bar and the vertical plane.

[0010] Furthermore, the smoothing component includes a guide spring, a bearing seat, and a synchronizing frame. The inner sides of the two arm-shaped structures of the curved fork arm are provided with sliding grooves. The guide spring is elastic and its two ends are slidably engaged in the sliding grooves. The guide spring moves closer to and further away from the middle of the curved fork arm between the two arm-shaped structures. The bearing seat is fixed on the inclined rod, and an outwardly expanding shaft tube is fixed on the bearing seat. The middle part of the synchronizing frame is rotatably connected to the outwardly expanding shaft tube and extends towards the guide spring. The end of the synchronizing frame is engaged with the middle part of the guide spring.

[0011] Furthermore, a perpendicular line is drawn between the axis of the outer expansion tube and the axis of the double-headed drive shaft, and the line points to the inside of the curved fork arm in the basic state.

[0012] Furthermore, a control board is fixed inside the inclined rod, and the drive assembly is electrically connected to the control board. A receiving electrode is fixed at the end of the bent fork arm, and the receiving electrode is electrically connected to the control board. An electric base is fixed on the crossbar, and the electric base includes a terminal and receiving springs electrically connected to both sides of the terminal. The terminal is connected to an external power supply device, and the receiving electrode of the bent fork arm, which is engaged with the crossbar, makes contact with the receiving springs.

[0013] Furthermore, the bottom of the inclined rod has an inwardly recessed slot. The drive assembly includes an outer fixed housing and a shifting motor fixed on the outer fixed housing. The outer fixed housing is embedded and engaged in the bottom slot and fixed to the inclined rod. The outer fixed housing and the bottom slot are in transition fit. A reduction gear set is provided inside the outer fixed housing. The double-headed drive shaft is rotatably connected to the outer fixed housing and is connected to the shifting motor through the reduction gear set.

[0014] Furthermore, the conveying mechanism has at least two parts, located at the beginning and end of the feeding assembly respectively. The conveying mechanism includes a base, a slide rail arranged along the length of the base, pulleys rotatably mounted on both sides of the base, and a transmission belt wound around the two pulleys. The pulleys are driven to rotate by a conveying motor. A lifting cylinder is slidably engaged on the slide rail. A transfer seat is fixed at the bottom of the lifting cylinder. The gripper cylinder is mounted on the transfer seat. The grippers used by the conveying mechanisms at the beginning and end of the feeding assembly are a flat gripper and a frame gripper, respectively. The flat gripper is used to grip the rod part of a horizontally placed frame, and the frame gripper is used to grip the frame part of a vertically suspended frame.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The conveyor line of the present invention uses a slanted bar at the front end of the drilling process to support the drum frame. The slanted bar is engaged with the crossbar of the machine frame through several shifting components. This allows the head of the slanted bar to continuously suspend the drum frame when it is suspended on the machine frame. By driving the shifting components to rotate in sequence, the drum frame at the head of the slanted bar is automatically conveyed to the tail end, where it is clamped onto the main machine head by the conveying mechanism. This overcomes the limitation of existing feeding crossbars, which are difficult to replenish materials because the feeding and discharging are at the same end. Attached Figure Description

[0029] 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.

[0030] Examples, such as Figures 1-9As shown: This invention provides a badminton racket forming production line. The production line structure includes a frame 1, a conveyor belt 2 located at the first end of the frame 1, a main head 4 located at the second end of the frame 1, and a drilling mechanism 7. The front end of the conveyor belt 2 supports manual operation, such as fixing the racket ring and shaft manually. After the racket is sent to several torsion testing devices for torsion testing, the racket frame 10 is transferred to the conveyor belt 2 after the torsion testing devices have completed the testing. The conveyor belt 2 transports the racket frames 10 arranged at intervals forward. A feeding component 8 and a conveying mechanism 3 are fixedly provided between the conveyor belt 2 and the main head 4. A translation mechanism 6 is connected between the bottom end of the main head 4 and the frame 1. The translation mechanism 6 is used to drive the main head 4 to move closer to and away from the frame in the horizontal direction. The drilling mechanism 7, in the prior art, the main head 4 has a rotating spindle, and a head clamp 5 is fixed on the spindle for holding the frame 10. The drilling mechanism 7 is used to drill holes in the frame 10 on the main head 4. The drilling mechanism 7 includes a drilling motor and a drill bit. A translation mechanism 6 is also connected between the drilling mechanism 7 and the frame 1. The translation mechanism 6 is used to drive the drilling mechanism 7 to move closer to and away from the main head 4 in the vertical direction. As those skilled in the art know, the translation mechanism 6 is a mechanism that drives the lead screw to rotate on the base body by a motor, so that the translation seat connected to the lead screw by the lead screw nut moves along the axis of the lead screw. This base body is fixed on the frame 1, and the moving translation seat is fixed to the main head 4 and the drilling motor.

[0031] The feeding assembly 8 is used to continuously provide the racket frame 10 to the main head 4 without switching the feeding structure. The conveying mechanism 3 is used to feed the feeding assembly 8, move the racket frame 10 from the feeding assembly 8 to the main head 4, and unload the racket frame 10 from the main head 4. A floor support 9 is fixed on the outside of the frame 1. A placement rod is fixed on the floor support 9 to receive the racket frame 10 with holes already drilled and unloaded from the main head 4 by the conveying mechanism 3.

[0032] The feeding assembly 8 includes a slanted rod 801 for suspending the racket frame 10. The slanted rod 801 is inclined, with its first end higher than its last end. At least three drive assemblies 803 and a shifting assembly 802 are mounted on the slanted rod 801. The first end of the slanted rod 801 faces the conveyor belt 2, allowing the racket frame 10 to enter the slanted rod 801. The top surface of the slanted rod 801 has a sliding surface 8012 for the suspended racket frame 10 to slide downwards along the inclined sliding surface 8012. The slanted rod 801 is made of a rigid material such as aluminum alloy profile, while the top sliding surface 8012 is covered with stainless steel. The surface of the stainless steel is polished using a mirror polishing process to form a smooth surface with a sliding friction coefficient of 0.30-0.40, allowing the racket frame to slide smoothly. The racket frame 10 can slide naturally downward along the inclined bar 801. The end of the inclined bar 801 is provided with a horizontal flat bearing section 8014. The sliding surface 8012 and the flat bearing section 8014 are connected by an arc-shaped smooth transition section 8013. The racket frame 10 sliding downward on the inclined bar 801 falls onto the flat bearing section 8014 and is stably placed in a naturally hanging state, forming a vertically downward placement shape, thus waiting for the handling mechanism 3 to clamp it. A limit frame 8015 is fixed on the flat bearing section 8014 to limit the space on the flat bearing section 8014 to only be able to hang one racket frame 10. This allows the last racket frame 10 to reach the designated position on the flat bearing section 8014 when there are only two racket frames 10 left on the inclined bar 801.

[0033] In this embodiment, the drive assembly 803 and the switching assembly 802 are provided in three sets. The diagonal bar 801 is engaged with the cross frame 101 through at least two switching assemblies 802 so that the diagonal bar 801 is suspended below the cross frame 101. The frame 1 includes a horizontal cross frame 101. A vertical stand 102 is fixed at the top of the frame 1 and extends downward. The cross frame 101 is fixed at the bottom of the stand 102. The switching assembly 802 is used for switching rotation and engaging with the cross frame 101. During the switching rotation, the frame 10 on the diagonal bar 801 is driven so that the frame 10 passes through the switching assembly 802 and slides downward to the next blocking structure. Only one switching assembly 802 rotates at a time.

[0034] Specifically, the drive assembly 803 is fixed to the bottom of the inclined rod 801. The drive assembly 803 includes a double-headed drive shaft 8031. The bottom of the inclined rod 801 has an inwardly recessed bottom slot 8011. The drive assembly 803 includes an outer fixed shell 8032 and a shifting motor 8033 fixed on the outer fixed shell 8032. The outer fixed shell 8032 is embedded and engaged in the bottom slot 8011 and fixed to the inclined rod 801. The outer fixed shell 8032 and the bottom slot 8011 are in transition fit. It should be noted that the fixed positions of the outer fixed shell 8032 and the inclined rod 801 are... Along the length of the diagonal bar 801, sufficient bending support is added to the diagonal bar 801 to compensate for the structural reduction caused by the bottom slot 8011. The outer fixed shell 8032 and the diagonal bar 801 are fixed by bolts. Washers can be nested on the bolts to control the installation depth of the outer fixed shell 8032. The outer fixed shell 8032 is equipped with a reduction gear set, which performs reduction transmission and reversing transmission in sequence through spur gears and helical gears. The double-headed transmission shaft 8031 ​​is rotatably connected to the outer fixed shell 8032 and is connected to the reversing motor 8033 through the reduction gear set.

[0035] Specifically, the switching component 802 includes a curved fork arm 8021, which is rotatably mounted on the diagonal bar 801. In this embodiment, two curved fork arms 8021 are provided and fixed to the drive shaft in the middle. The two sides of the middle part of the curved fork arm 8021 have arm-like structures, making the curved fork arm 8021 bend as a whole. The arm-like structures are used to push the frame 10 on the diagonal bar 801 during rotation and to engage with the crossbar 101 to suspend the diagonal bar 801. The curved fork arm 8021 has a basic state, in which the inner sides of several curved fork arms 8021 all point towards the head end of the diagonal bar 801 and the curved fork arms 8021 are all engaged with the crossbar 101, that is, the inner side of each curved fork arm 8021 is ready to receive When the racket frame 10 is in the engaged state, the arm-shaped structure that engages with the crossbar 101 forms a blocking structure in the vertical direction to block the racket frame 10 on the diagonal bar 801. Starting from the head end of the diagonal bar 801, the first blocking structure blocks all the racket frames 10 that have entered. When needed, the diagonal bar 801 swings from the head to the tail. The inner side of the arm-shaped structure that swings from the head to the tail of the diagonal bar 801 forms a pushing structure on the diagonal bar 801 to push the racket frames 10 on the diagonal bar 801. The curved fork arm 8021 drives a certain number of racket frames 10 to cross the curved fork arm 8021 and reach the next blocking structure. Then the first curved fork arm 8021 resets and continues to form a blocking structure, and so on.

[0036] It should be noted that an arm-shaped structure of the curved fork arm 8021 near the head of the diagonal bar 801 has a limiting plate 8027 fixed on the side away from the opposite arm-shaped structure. The outer edge of the limiting plate 8027 is arc-shaped, and the radius of the outer edge of the arc-shaped limiting plate 8027 is equal to the length of the arm-shaped structure. The degree of the central angle of the outer edge of the limiting plate 8027 is greater than the degree of the angle between the diagonal bar 801 and the vertical plane. The limiting plate 8027 is fixed on the arm-shaped structure in the basic state and has the tendency to form a pushing structure. That is, after the first curved fork arm 8021 rotates, this arm-shaped structure will swing upward to push the racket frame 10 on the diagonal bar 801. Therefore, the limiting plate 8027 on the back of this arm-shaped structure will rotate out with it after its rotation, blocking the racket frame 10 that is about to slide down above the diagonal bar 801, and preventing the racket frame 10 from getting stuck between the arm-shaped structure and the diagonal bar 801 when the first curved fork arm 8021 is reset.

[0037] The arm-shaped structure has a protruding push head 8023 at its end, and a recessed engagement groove 8024 is formed on the inner side of the push head 8023. The cross frame 101 includes a hanging platform 1011 at the top and a top support surface 1012 at the bottom. The engagement groove 8024 is clearance-fitted with the cross frame 101. When the inclined rod 801 is under uniform force, the engagement groove 8024 presses down and hangs on the top support surface 1012. When one end of the inclined rod 801 is under heavier force, the engagement groove 8024 pushes against the top support surface 1012. A sliding spring strip 8022 is fixedly provided on the side end of the arm-shaped structure. The sliding spring strip 8022 is an elastic strip and extends from one end of the engagement groove 8024 towards the bite. The other end of the engagement groove 8024 extends to prevent the frame 10 from falling into the engagement groove 8024 when the arm-shaped structure moves the frame 10. During the engagement of the engagement groove 8024 and the crossbar 101, the sliding spring 8022 will gradually accumulate, preventing the sliding spring 8022 from affecting the engagement of the engagement groove 8024 and the crossbar 101. At the same time, an elastic surrounding spring 1013 is provided on the edge of the crossbar 101. When the engagement groove 8024 and the crossbar 101 are engaged, the surrounding spring 1013 acts as a lateral block for the engagement groove 8024, reducing the displacement of the engagement groove 8024 caused by shaking.

[0038] It should be noted that the angle between the inclined bar 801 and the horizontal plane ranges from 6° to 10°. In this embodiment, 6° is used, so that the inclined bar 801 can have relatively stable force even when only the two shifting components 802 are fixed to the crossbar 101, while ensuring the conveying distance. The two arm-shaped structures of the curved fork arm 8021 have an angle between them, ranging from 90° to 105°. In this embodiment, 90° is used. Furthermore, the sliding surface 8012 at the top of the inclined bar 801 is raised from both sides towards the middle. The racket frame 10 suspended on the sliding surface 8012 contacts the middle of the sliding surface 8012, that is, the sliding surface 8012 and the racket frame 10 form a line contact in the middle. The horizontal height of the two sides of the sliding surface 8012 is... The horizontal height of the end of the arm-shaped structure, which is lower than the top of the frame 10 and tends to form a blocking structure, is lower than the horizontal height of the sides of the sliding surface 8012. That is, the arm-shaped structure of the curved fork arm 8021 after swinging upward from the base state should be below the middle of the sliding surface 8012 and further below the sides of the sliding surface 8012 to avoid contact with the frame 10 and affect the sliding of the frame 10 along the sliding surface 8012. The distance between the double-headed drive shaft 8031 ​​and the sliding surface 8012 can be controlled by adjusting the installation depth of the drive assembly 803 in the bottom slot 8011, so that the curved fork arm 8021 fixed on the double-headed drive shaft 8031 ​​is closer to or further away from the sliding surface 8012.

[0039] It should be noted that the first and last ends of the diagonal bar 801 have stationary spaces for suspending the racket frames 10. The two ends of the two stationary spaces are the edge of the diagonal bar 801 and the edge of the range of motion of the end of the curved fork arm 8021 adjacent to the edge, respectively. The length of the stationary space is greater than the length of the arm-like structure of the curved fork arm 8021. The length of the arm-like structure allows it to move 10 racket frames 10 at a time, and the length of the stationary space allows it to support 11 racket frames 10. Thus, the first end of the diagonal bar 801 can support 21 racket frames 10. The racket frame 10 has more capacity to support more racket frames 10. Ten of them are located within the range of the curved fork arm 8021 and wait for the curved fork arm 8021 to rotate and drive them. After these 10 are delivered, they can be quickly replenished after resetting. The stationary space at the end of the slant bar 801 can also support 11 racket frames 10. After the curved fork arm 8021 at the end of the slant bar 801 delivers 10 racket frames 10 to the end, there is still one empty space to prevent the curved fork arm 8021 from taking the racket frames 10 in the stationary space back after resetting.

[0040] In this embodiment, a control board 805 is fixed inside the diagonal bar 801. The drive assembly 803 is electrically connected to the control board 805. The control board 805 includes a main control board and a power module, i.e., a power supply, which is used to stabilize and transform the external power supply and supply it to the main control board. The main control board is a motherboard in the prior art, used to distribute and control the power supply to the transposition motor 8033. An electrode plate 8025 is fixed at the end of the bent fork arm 8021. The electrode plate 8025 is electrically connected to the control board 805 through wires. The crossbar 10 An electric base 104 is fixed on the 1. The electric base 104 includes a terminal 1041 and a contact spring 1042 electrically connected to both sides of the terminal 1041. The terminal 1041 is connected to an external power supply device through a wire. The contact plate 8025 of the bent fork arm 8021, which is engaged on the crossbar 101, makes contact with the contact spring 1042 to make the circuit conductive. Since the diagonal rod 801 is fixed to the crossbar 101 through at least two bent fork arms 8021, the control board 805 has a continuous power input available for distribution.

[0041] In this embodiment, a smoothing component 804 is provided on the inner side of the curved fork arm 8021. Since there are curved fork arms 8021 on both sides of the inclined bar 801, when the arm-shaped structure drives the frame 10 to move, the frame 10 is supported and driven to move on both sides. There are two support points. Since the curved fork arm 8021 is bent, it may fall directly from the position of the two support points to the sliding surface 8012 of the inclined bar 801 during the driving process, and there is only one support point between it and the sliding surface 8012, without a transition stage. Therefore, the smoothing component 804 is used to form an arc support for the frame 10 pushed by the arm-shaped structure after the curved fork arm 8021 swings, without affecting the position of the frame 10 in the basic state.

[0042] The smoothing component 804 includes a guide spring strip 8041, a bearing seat 8042, and a timing frame 8043. The inner sides of the two arm-shaped structures of the curved fork arm 8021 are provided with sliding grooves 8026. The guide spring strip 8041 is made of stainless steel, is elastic, and its two ends slide and engage within the sliding grooves 8026. The middle part forms a curved structure between the two arm-shaped structures, allowing the guide spring strip 8041 to move closer to and further away from the middle of the curved fork arm 8021 between the two arm-shaped structures. The bearing seat 8042 is fixed to the inclined rod 801, and an outwardly expanding shaft tube 8044 is fixed to the bearing seat 8042. The middle part of the timing frame 8043 is rotatably connected to the outwardly expanding shaft tube 8044 and extends towards the guide spring strip 8041. The end of the timing frame 8043 engages with the middle of the guide spring strip 8041.

[0043] It should be noted that by making a perpendicular line connecting the axis of the outer expansion tube 8044 and the axis of the double-headed drive shaft 8031, the line points to the inside of the bent fork arm 8021 in the basic state. That is, the bearing seat 8042 and the outer expansion tube 8044 are located on the drive assembly 803 along the downward position of the inclined rod 801. This makes the distance from the middle of the bent fork arm 8021 in the basic state to the outer expansion tube 8044 greater than the distance from the middle of the bent fork arm 8021 after swinging to the outer expansion tube 8044. This allows the synchronous frame 8043 to pull the guide spring 8041 inward on the bent fork arm 8021 in the basic state, and to push the guide spring 8041 outward on the bent fork arm 8021 after swinging.

[0044] In this embodiment, the conveying mechanism 3 includes a gripper cylinder 307 that moves on the frame 1 and a gripper mounted on the gripper cylinder 307, which is used to drive the frame 10 to move inward to the inner side of the first end of the inclined rod 801 and outward to the outer side of the tail end of the inclined rod 801. Specifically, the conveying mechanism 3 is provided with at least two and is located at the first end and the tail end of the feeding assembly 8 respectively. In this embodiment, the conveying mechanism 3 is provided with three, which are located at the first end and the tail end of the feeding assembly 8, and above the main head 4 respectively.

[0045] The conveying mechanism 3 includes a base 301, a slide rail 302 arranged along the length of the base 301, pulleys 303 rotatably mounted on both sides of the base 301, and a transmission belt 312 wound around the two pulleys 303. The pulleys 303 are driven to rotate by a conveying motor 304. A lifting cylinder 305 is slidably engaged on the slide rail 302. A transfer seat 306 is fixed to the bottom of the lifting cylinder 305, and a gripper cylinder 307 is mounted on the transfer seat 306. The grippers used in the conveying mechanism 3 at the beginning and end of the feeding assembly 8 are flat grippers 308 and frame grippers 311, respectively. The handling mechanism 3 uses a frame gripper 311, a flat gripper 308 for gripping the rod of the horizontally placed frame 10, and a frame gripper 311 for gripping the frame of the vertically suspended frame 10. The gripper cylinder 307 equipped with the flat gripper 308 is directly fixed on the intermediate transfer seat 306. The gripper cylinder 307 equipped with the frame gripper 311 is rotatably mounted on the intermediate transfer seat 306. A swing motor 309 is fixed on the side of the intermediate transfer seat 306. The swing motor 309 has a rotating shaft 310. The gripper cylinder 307 is fixed on the rotating shaft 310 and is driven by the swing motor 309 to swing.

[0046] In summary, during implementation, after the racket ring and shaft are manually fixed, they are sent to several torsion testing devices for torsion testing. After the torsion testing devices are completed, the racket frame 10 is transferred to the conveyor belt 2. The conveyor belt 2 transports the racket frames 10, which are arranged at intervals, forward to the transport mechanism 3. At the transport mechanism 3, the gripper cylinder 307 drives the flat grippers 308 on both sides to clamp the shaft of the racket frame 10. Then, the lifting cylinder 305 drives the racket frame 10 to rise, and the transport motor 304 drives the transmission belt 31. 2. Move the lifting cylinder 305 and the racket frame 10 above the head of the inclined bar 801. Then, the flat clamp 308 releases the racket frame 10 and lets it fall onto the inclined bar 801. The racket frame 10 hangs naturally on the inclined bar 801 by the weight of the bar. The bottom of the frame 1 is provided with a base 105 and a recessed converging guide groove 103 is provided on the top of the base 105 along the length of the inclined bar 801 to guide the bar of the racket frame 10 so that the racket frame 10 is arranged neatly.

[0047] Several racket frames 10 are arranged and suspended on the diagonal bar 801. The drive assembly 803 drives the double-headed transmission shaft 8031 ​​to rotate, thereby causing the first set of curved fork arms 8021 on the diagonal bar 801, starting from the head, to rotate downwards, causing the engagement groove 8024 to disengage from the crossbeam 101. At this time, the diagonal bar 801 is hung on the crossbeam 101 by the other two curved fork arms 8021. Simultaneously, another arm-like structure of the curved fork arm 8021, along with the limiting plate 8027, rotates upwards, and the arm-like structure pushes upwards. The head 8023 opens the gap of the racket frame 10 on the inclined rod 801, allowing the arm-like structure to push a certain amount of the racket frame 10. This certain amount of the racket frame 10, following the rotation of the curved fork arm 8021, begins to slide downwards along the inner side of the arm-like structure and the sliding surface 8012 of the inclined rod 801. During the rotation of the curved fork arm 8021, the timing frame 8043 swings accordingly. The pulling effect of the timing frame 8043 on the guide spring 8041 transforms into a spreading effect, thereby allowing the guide spring 8041 to... The middle part, away from the center of the curved fork arm 8021, forms a large arc, assisting the frame 10 to slide down relatively gently. After the curved fork arm 8021 has fully rotated, the upward-rotating arm-like structure engages with the top crossbar 101 through the engagement groove 8024. The downward-swinging curved fork arm 8021 also disengages from obstructing the sliding frame 10, allowing the frame 10 to slide naturally on the sliding surface 8012 onto the obstructing structure formed by the next curved fork arm 8021, etc. After the first set of curved fork arms 8021 rotates and resets, the second set of curved fork arms 8021 can rotate to further transport the racket frame 10. A certain amount of racket frames 10 previously transported by the first set are transported by the second set to the third set at once. The third set does the same. After the third set transports the racket frame 10 to the stationary space at the end of the inclined bar 801, each set of curved fork arms 8021 resets until the next cycle begins. The racket frames 10 in the stationary space at the end of the inclined bar 801 then slide down naturally.

[0048] The bottom racket frame 10 slides onto the flat support section 8014 and rests against the limiting frame 8015, waiting for the frame clamp 311 of the conveying mechanism 3 to clamp it and then rise. The swing motor 309 then drives the racket frame 10 to swing around the axis 310, avoiding the inclined frame, and then moves horizontally to the head clamp 5 of the main unit head 4 for clamping. The head clamp 5 is typically a set of expandable plates that support the inner side of the racket frame 10. Then, the drill bit rises and falls to drill holes in the racket frame 10. Furthermore, the main head 4 rotates to make the drill bit drill around the frame 10. After the drilling operation is completed, the main head 4 moves backward to avoid the position of the drilling mechanism 7. The frame clamp 311 of the conveying mechanism 3 at the top of the main head 4 clamps the frame 10 on the machine head clamp 5 and moves it to the outside of the frame 1. Before reaching the placement rod, the frame 10 is first swung upward, and then it is moved to the placement rod and swung back to the vertical state. The frame 10 is then lowered and suspended on the placement rod. It is then removed after a certain amount of time.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
