Description

Technical Field

[0001] The invention relates to a detection machine, in particular to a badminton detection machine applied to the badminton detection field. Background Art

[0002] With the improvement of people's living standards, more and more people like badminton, and the badminton industry has achieved unprecedented development. After a long period of development, my country's badminton enterprises have become more and more specialized, including badminton feathers, badminton heads, badminton strings, etc. The technological content is getting higher and higher, and the competition is becoming more and more fierce. Therefore, each enterprise must improve its production technology in order to be competitive in the market.

[0003] In my country's badminton manufacturing companies, badminton needs to be inspected before leaving the factory, but my country basically adopts the method of manual hitting inspection. Although this method is easy to use, the inspection efficiency is slow and the inspection quality is unstable.

[0004] In order to solve the problems of slow detection efficiency and unstable detection quality, a badminton detection machine on the market adopts a mechanically driven design for automatic ball retrieval and hitting, and has a certain market share.

The invention has the advantages of reasonable structural design and convenient use, can realize automatic detection of badminton and replace manual detection, has a high degree of automation, improves the detection efficiency of badminton, saves manpower and material resources, and uses the hitting device to hit the badminton, ensures the flight speed of the badminton, and ensures the detection quality of the badminton.

[0006] The structure of the badminton testing machine designed above has multiple power sources to drive the movement of various components to realize a series of testing actions such as taking the ball, returning to the position, and hitting the ball. There needs to be gaps between the coordination of multiple actions, and the time of a single test is relatively long. In actual use, additional control equipment and control systems are required to realize the coordinated drive between multiple power sources to achieve the purpose of detection; the equipment cost is relatively high, and the energy consumption of multiple power sources in the test is relatively large, and the detection cost increases accordingly. Summary of the invention

[0007] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to shorten or eliminate the time interval between each action, ensure the smoothness of the action, improve the test efficiency, and at the same time reduce the setting of the power source while ensuring the test effect, thereby reducing the equipment cost and the detection cost.

[0008] In order to solve the above problems, the present invention provides a badminton detection machine, including a mounting hanger and a mounting box, wherein a ball outlet tube and a driving motor are respectively fixed at both ends of the mounting hanger, a driving shaft that rotates and penetrates the mounting hanger is fixed at the lower end of the output shaft of the driving motor, and the lower end of the driving shaft rotates and penetrates the top wall of the mounting box, and a fixing plate and a rotating shaft are fixed on one side of the mounting box away from the ball outlet tube; A movable rod is fixed on the driving shaft, a ball receiving frame is fixed on one end of the movable rod, and the rotation path of the ball receiving frame is located below the ball outlet cylinder; One end of the fixing plate away from the installation box is rotatably connected with a hitting racket, and the hitting racket is elastically connected to one side of the installation box through a follow-up tension mechanism in an adjustable manner; A transmission assembly for driving the follower tension mechanism to adjust the distance is installed on the driving shaft, and the transmission assembly operates synchronously with the driving shaft; A support rod group is fixed at one end of the rotating shaft away from the installation box. The support rod group is composed of four support rods distributed in a "cross" shape. The support rod group is located between the movable rod and the hitting racket. When the support rod group is kept vertical, the lower end of one of the support rods is pressed against the hitting racket to keep the hitting racket horizontal. When the ball receiving frame moves to the top of the batting racket, the lower end of the rod assembly separates from the batting racket, and the batting racket rotates under the elastic force of the follower tension mechanism and hits the badminton in the ball receiving frame; A ball-catching plate for catching the badminton is arranged at the lower end of the ball-discharging cylinder, and a follow-up opening and closing mechanism for driving the ball-catching plate to deflect is also arranged at the lower end of the mounting hanging plate. When the ball-receiving frame rotates to the bottom of the ball-discharging cylinder, the movable rod drives the ball-catching plate to deflect and open through the follow-up opening and closing mechanism.

[0009] In the above-mentioned badminton detection machine, first, the rod group is kept vertical, and the lower end of one of the rods presses against the batting racket and keeps the batting racket horizontal. At this time, the movable rod deviates from the batting racket and the ball receiving frame also deviates from the batting racket. When the driving motor drives the driving shaft to rotate, it drives the movable rod to rotate along the driving shaft. The movable rod drives the ball receiving frame to move to the bottom of the ball outlet tube. At this time, the movable rod drives the ball blocking plate to deflect and open through the follow-up opening and closing mechanism, so that the badminton falls into the ball receiving frame. When the movable rod leaves, the follow-up opening and closing mechanism drives the ball blocking plate to deflect and close the ball outlet tube again so that the next badminton is stuck and positioned. The movable rod continues to move forward to drive the ball receiving frame to rotate and approach the rod group, and drives the upper rod to rotate, and the lower rod rotates away from the batting rack. After losing resistance, the batting rack rotates upward under the pulling force of the follow-up pulling mechanism and hits the badminton in the ball receiving frame, thereby completing the flight test of the badminton. During the test, by using two components, a follow-up tension mechanism and a follow-up opening and closing mechanism, it is possible to use the same power output source to complete a series of test actions of catching the ball, running, hitting the ball and then catching the ball. The actions are coherent and unified. Compared with combining multiple actions to complete the test, the single test time is shorter and the test efficiency is high. It does not require multiple power sources to output power, which saves power consumption. At the same time, there is no need to be equipped with an additional control system. It only needs to control the single rotation angle and rotation speed of the drive motor to adjust the test process. Compared with the existing badminton testing machine, the equipment cost of this testing machine is lower, the energy consumption during testing is less, and it has a good promotion prospect.

[0010] As a further supplement to this application, the follow-up tension mechanism includes: A slide rail, the slide rail is fixed to a side wall of one side of the installation box; A slider, the slider is slidably connected in the slide rail; A hitting spring, one end of which is fixed to the lower end of the slider, and the other end of which is located on the side of the support rod assembly close to the mounting box and fixed to the middle of the hitting racket; The slide block is driven by the transmission assembly to rise along the slide rail.

[0011] As a further supplement to this application, the transmission assembly includes: A sector gear, the sector gear is fixedly sleeved on the driving shaft; A driven gear, the driven gear meshes with the sector gear; A transmission shaft, which is fixedly passed through the driven gear and is rotatably connected to the top wall of the mounting box; A winding wheel, which is fixed to the lower end of the transmission shaft and is coaxially arranged with the transmission shaft; A connecting rope is wound on the winding wheel, and the other end of the connecting rope passes through one side of the installation box and is fixed to the upper end of the sliding block.

[0012] As a further supplement to the present application, the tooth block distribution angle of the sector gear is greater than 90° and less than 180°; The diameter of the winding wheel is larger than the diameter of the driven gear and is in multiple relationship.

[0013] As a further supplement to the present application, the follow-up opening and closing mechanism includes: A connecting rod, the connecting rod is fixedly connected to one side of the ball-blocking plate through a connecting plate; The shifting block is rotated, and the shifting block is fixed to an end of the connecting rod away from the ball-clamping plate; A fixed shaft, one end of which is fixed to the lower end of the mounting hanger plate through a connecting piece, and the other end of which is rotatably connected to a side of the rotating shift block away from the connecting rod; When the movable rod rotates to make the ball receiving frame move to just below the ball outlet tube, the upper surface of the movable rod abuts against the bottom surface of the rotating shift block to make the rotating shift block horizontal, and at the same time, the connecting rod rotates along the axis of the fixed shaft to drive the ball blocking plate to deflect and open.

[0014] As a further supplement to the present application, the upper surface of one end of the rotating shift block away from the connecting rod is elastically connected to the bottom surface of the mounting hanger plate through a return spring.

[0015] As a further supplement to the present application, the rotating block is in an inclined "L"-shaped structure, and the angle formed between the two parts of the rotating block is an obtuse angle.

[0016] As a further supplement to the present application, the connecting member includes a vertically arranged fixed plate, the upper end of the fixed plate is fixed to the lower end of the mounting hanger plate, one end of the fixed shaft is fixed to one side of the fixed plate, and the horizontal height of the lower end of the fixed plate is higher than the horizontal height of the upper end of the movable rod.

[0017] As a further supplement to the present application, one end of the ball retaining plate is provided with a "U"-shaped opening that matches the ball outlet tube, and the inner diameter of the opening is smaller than the inner diameter of the ball outlet tube.

[0018] To summarize, first, the lever group is kept vertical, and the lower end of one of the levers is pressed against the batting racket and keeps the batting racket horizontal. At this time, the movable rod deviates from the batting racket and the ball receiving frame also deviates from the batting racket. When the driving motor drives the driving shaft to rotate, it drives the movable rod to rotate along the driving shaft. When the movable rod rotates to the point where the ball receiving frame is close to the bottom of the ball outlet tube, one side of the movable rod abuts against the bottom surface of the rotating shift block and gradually pushes the rotating shift block to make the rotating shift block horizontal. At this time, the connecting rod rotates along the axis of the fixed shaft to drive the ball clamping plate to gradually deflect and open, and fully open when the ball receiving frame is located under the ball outlet tube, thereby allowing the badminton to fall into the ball receiving frame and complete the badminton retrieval action. After the ball receiving frame continues to rotate with the movable rod to leave the bottom of the ball outlet tube, the rotating shift block rotates and resets under the action of the reset spring, allowing the clamping plate to The racket is reset again, and the next badminton level is locked and limited to prevent the badminton from falling off. The movable rod continues to drive the ball receiving frame to rotate toward the push rod group. When the fan gear rotates to a certain angle, it meshes with the driven gear. The driven gear further drives the winding wheel to rotate through the transmission shaft, so that the connecting rope is wound around the winding wheel. The connecting rope contracts to make the slider move up along the slide rail, stretching the hitting spring and accumulating a large pulling force. Then the movable rod contacts the upper push rod of the push rod group to make it rotate, and the lower push rod rotates and leaves the hitting racket. After the hitting rack loses resistance, it rotates along the rotating connection between it and the fixed plate under the pulling force of the hitting spring, and finally the hitting racket rotates a certain angle and hits the badminton placed in the ball receiving frame, so that the badminton flies, thereby completing the badminton flight test. During the test, by using two components, a follow-up tension mechanism and a follow-up opening and closing mechanism, it is possible to use the same power output source to complete a series of test actions of catching the ball, running, hitting the ball and then catching the ball. The actions are coherent and unified. Compared with combining multiple actions to complete the test, the single test time is shorter and the test efficiency is high. It does not require multiple power sources to output power, which saves power consumption. At the same time, there is no need to be equipped with an additional control system. It only needs to control the single rotation angle and rotation speed of the drive motor to adjust the test process. Compared with the existing badminton testing machine, the equipment cost of this testing machine is lower, the energy consumption during testing is less, and it has a good promotion prospect.

DETAILED DESCRIPTION

[0021] An implementation method of the present application is described in detail below with reference to the accompanying drawings.

[0022] The first implementation method: The present invention provides a badminton detection machine, please refer to Figure 1-Figure 3 , including a mounting hanger plate 1 and a mounting box 2, the two ends of the mounting hanger plate 1 are respectively fixed with a ball outlet cylinder 5 and a driving motor 6, the lower end of the output shaft of the driving motor 6 is fixed with a driving shaft 10 that rotates and penetrates the mounting hanger plate 1, the lower end of the driving shaft 10 rotates and penetrates the top wall of the mounting box 2, and a fixing plate 17 and a rotating shaft are fixed to the side of the mounting box 2 away from the ball outlet cylinder 5; A movable rod 3 is fixed on the driving shaft 10, and a ball receiving frame 19 is fixed at one end of the movable rod 3. The rotation path of the ball receiving frame 19 is located below the ball outlet cylinder 5; The end of the fixing plate 17 away from the installation box 2 is rotatably connected to the hitting racket 4, and the hitting racket 4 is elastically connected to one side of the installation box 2 through a follower tension mechanism 8 in an adjustable manner; A transmission assembly for driving the follower tension mechanism 8 to adjust the distance is installed on the drive shaft 10, and the transmission assembly operates synchronously with the drive shaft 10; A rod group 7 is fixed to one end of the rotating shaft away from the mounting box 2. The rod group 7 is composed of four rods arranged in a "cross" shape. The rod group 7 is located between the movable rod 3 and the hitting racket 4. When the rod group 7 is kept vertical, the lower end of one of the rods is pressed against the hitting racket 4 to keep the hitting racket 4 horizontal. When the ball receiving frame 19 moves to the top of the hitting racket 4, the lower end of the rod assembly 7 separates from the hitting racket 4. At this time, the hitting racket 4 rotates under the elastic force of the follower tension mechanism 8 and hits the badminton in the ball receiving frame 19. A ball-catching plate 21 for catching the badminton is provided at the lower end of the ball-discharging tube 5, and a follow-up opening and closing mechanism 9 for driving the ball-catching plate 21 to deflect is also installed at the lower end of the mounting hanger 1. When the ball receiving frame 19 rotates to the bottom of the ball-discharging tube 5, the movable rod 3 drives the ball-catching plate 21 to deflect and open through the follow-up opening and closing mechanism 9.

[0023] Based on the above structure, the rod group 7 is first kept vertical, and the lower end of one of the rods is pressed against the hitting racket 4 to keep the hitting racket 4 horizontal. At this time, the movable rod 3 deviates from the hitting racket 4 and the ball receiving frame 19 also deviates from the hitting racket 4. Figure 7 When the driving motor 6 drives the driving shaft 10 to rotate, the movable rod 3 is driven to rotate along the driving shaft 10, and the movable rod 3 drives the ball receiving frame 19 to move to the bottom of the ball outlet tube 5. At this time, the movable rod 3 drives the ball clamping plate 21 to deflect and open through the follow-up opening and closing mechanism 9, so that the badminton falls into the ball receiving frame 19. Figure 8When the movable rod 3 leaves, the follower opening and closing mechanism 9 drives the ball-catching plate 21 to deflect and close the ball-discharging tube 5 again, so that the next badminton is stuck and positioned. The movable rod 3 continues to drive the ball-receiving frame 19 to rotate toward the push rod group 7, and drives the upper push rod to rotate, and the lower push rod rotates and leaves the hitting racket 4. After losing resistance, the hitting racket 4 rotates upward under the pulling force of the follower pulling mechanism 8 and hits the badminton in the ball-receiving frame 19. Reference can be made here Figure 6 , thus completing the flight test of badminton; During the test, by using the follow-up tension mechanism 8 and the follow-up opening and closing mechanism 9, it is possible to use the same power output source to complete a series of test actions of catching the ball, running, hitting the ball and then catching the ball. The actions are coherent and unified. Compared with combining multiple actions to complete the test, the single test time is shorter and the test efficiency is high. It does not require multiple power sources to output power, which saves power consumption. At the same time, there is no need to equip an additional control system. It only needs to control the single rotation angle and rotation speed of the drive motor 6 to adjust the test process. Compared with the existing badminton testing machine, the testing machine has lower equipment cost and less energy consumption during testing, and has good promotion prospects.

[0024] Figure 2 The follow-up tension mechanism 8 is shown to include: A slide rail 15, the slide rail 15 is fixed to a side wall of one side of the installation box 2; A slider 16, the slider 16 is slidably connected in the slide rail 15; A hitting spring 18, one end of which is fixed to the lower end of the slider 16, and the other end of which is located on the side of the support rod group 7 close to the mounting box 2 and fixed to the middle of the hitting racket 4; The slide block 16 is driven by the transmission assembly to rise along the slide rail 15 .

[0025] When the upper rod of the rod group 7 rotates, causing the lower rod to rotate accordingly and leave the hitting racket 4, the hitting racket 4 rotates along the rotating connection between it and the fixed plate 17 under the pulling force of the hitting spring 18, and finally the hitting racket 4 rotates a certain angle and hits the badminton placed in the ball receiving frame 19, causing the badminton to fly, completing the flight test.

[0026] Figure 2 The transmission assembly is shown to include: The sector gear 11 is fixedly sleeved on the driving shaft 10; A driven gear 12, the driven gear 12 is meshed with the sector gear 11; A transmission shaft 13, which is fixedly passed through the driven gear 12 and is rotatably connected to the top wall of the mounting box 2; The winding wheel 14 is fixed to the lower end of the transmission shaft 13 and is coaxially arranged with the transmission shaft 13; A connecting rope is wound on the winding wheel 14 , and the other end of the connecting rope passes through one side of the installation box 2 and is fixed to the upper end of the slider 16 .

[0027] When the driving shaft 10 rotates, the fan gear 11 is synchronously driven to rotate. When the fan gear 11 rotates to a certain angle, it meshes with the driven gear 12. At this time, the movable rod 3 drives the ball receiving frame 19 to rotate toward the lever group 7. The driven gear 12 further drives the winding wheel 14 to rotate through the transmission shaft 13, so that the connecting rope is wound around the winding wheel 14. The contraction of the connecting rope causes the slider 16 to move up along the slide rail 15, stretching the hitting spring 18 and accumulating a large pulling force, so that the hitting spring 18 can pull the hitting racket 4 to rotate quickly to hit the badminton after the lower lever of the lever group 7 leaves the hitting racket 4 (at this time the fan gear 11 is still meshed with the driven gear 12), thereby completing the badminton flight test.

[0030] When the movable rod 3 rotates to the point where the ball receiving frame 19 is close to the bottom of the ball outlet tube 5, one side of the movable rod 3 abuts against the bottom surface of the rotating block 23 and gradually pushes the rotating block 23 to make it horizontal. At this time, the connecting rod 22 rotates along the axis of the fixed shaft 25 to drive the ball blocking plate 21 to gradually deflect and open, and fully open when the ball receiving frame 19 is located under the ball outlet tube 5, so that the badminton falls into the ball receiving frame 19, completing the badminton retrieval action.

[0031] Figure 3It is shown that the upper surface of the end of the rotating block 23 away from the connecting rod 22 is elastically connected to the bottom surface of the mounting hanger plate 1 through a return spring 24; the rotating block 23 is an inclined "L"-shaped structure, and the angle formed between the two parts of the rotating block 23 is an obtuse angle; After the ball receiving frame 19 continues to rotate with the movable rod 3 to leave the bottom of the ball outlet tube 5, the rotating shift block 23 rotates and resets under the action of the reset spring 24, so that the ball blocking plate 21 is reset again, and the next badminton level is locked and limited to prevent the badminton from falling off.
