Description

Technical Field

[0001] The utility model belongs to the technical field of table tennis ball picking, in particular to an automatic table tennis ball picking device. Background Art

[0002] Table tennis is a ball sport that includes attack, confrontation and defense. The conditions for playing table tennis are not harsh, and it is highly participatory and can be played by men, women, young and old. Therefore, it is deeply loved by young people and the elderly. At the same time, table tennis is a whole-body exercise that can strengthen the body, brain and heart. The activity intensity is not high, and it can have a good exercise effect. Table tennis is basically played indoors. Since table tennis balls are small in size, light in weight and have good elasticity, they will roll far away if you are not careful. The irregular scattering of table tennis balls makes it more difficult to collect them, and the continuous bending down of people to pick up the balls wastes time and consumes physical strength, and the efficiency of picking up the balls is low.

[0003] Existing automatic table tennis ball picking machines are generally divided into three categories. The first type uses a rotating shaft to drive a paddle to move the ball to a storage warehouse. Because table tennis balls are light in weight and have good elasticity, they are easily bounced off when the two collide, resulting in low stability in the recovery process; the second type uses a mechanical arm to clamp and pick up the ball and put it in a storage bin. This type of ball picking machine can only pick up one ball at a time, so the operation efficiency is not high; the third type uses the principle of a vacuum cleaner to suck the table tennis balls into the storage bin through a fan. This type of ball picking machine requires the addition of a fan, has high noise and volume, and is not convenient for indoor use. Utility Model Content

[0029] Example 1

[0030] like Figure 1-Figure 5As shown, it is a structural diagram of an automatic table tennis ball picking device provided by the utility model, comprising: a shell 1 with an opening at the bottom, a movable lifting assembly 2 arranged on both sides of the bottom of the shell 1 and used to drive the shell 1 to move and lift, at least two conveying screws 3 rotatably installed inside the shell 1 and arranged in parallel and spaced apart, a feed port and a discharge port respectively opened at the front and rear ends of the shell 1 and opposite to the middle positions of two adjacent conveying screws 3, a ball collecting box 4 fixedly arranged at the rear end of the shell 1 and connected to the discharge port, a driving assembly 5 connected to each of the conveying screws 3 and used to drive the same to rotate, a detection module 6 fixedly arranged on the shell 1 and used to identify a target object in the field of view, and a control unit 7 simultaneously connected to the movable lifting assembly 2, the detection module 6 and the driving assembly 5 by signal.

[0031] In actual application of this embodiment, when the user is playing table tennis and needs to pick up the ball, the control unit 7 controls the mobile lifting assembly 2 to drive the shell 1 to move, and the detection module 6 detects in real time whether there is a target object in the field of view and transmits a signal to the control unit 7. When the detection module 6 finds the table tennis ball in the field of view, the control unit 7 receives the information of the detection module 6 and sends a signal to the mobile lifting assembly 2, thereby driving the shell 1 to move to the target position; in the process of the shell 1 moving forward, the table tennis ball gradually moves along the feed port between the two conveying screws 3, and then the shell 1 gradually descends to a suitable height under the action of the mobile lifting assembly 2. Under the action of the driving assembly 5, the conveying screw 3 rotates and descends, thereby wrapping the table tennis ball moved from the feed port, thereby conveying the table tennis ball along the two adjacent conveying screws 3, and finally the shell 1 is transmitted from the discharge port and placed in the ball collection box 4 located at the rear end of the shell 1, thereby completing the automatic picking up of the table tennis ball. The whole process is fully automated to ensure the picking efficiency, and at the same time, the noise and volume are small, which is convenient to meet the user's usage needs.

[0032] Furthermore, the mobile lifting components 2 are symmetrically fixed on both sides of the bottom of the shell 1, and two groups are provided on each side of the shell 1. The mobile lifting components 2 are symmetrically arranged on both sides of the bottom of the shell and two groups are provided on each side, so as to ensure the stable movement and lifting adjustment of the shell 1.

[0033] Furthermore, the mobile lifting assembly 2 includes: a first driving member 21 fixedly mounted on the side of the shell 1, a rotating member 22 having one end connected to the output end of the first driving member 21, a second driving member 23 fixedly mounted on the inner side of the rotating member 22, and a rotating wheel 24 rotatably mounted on one end of the rotating member 22 away from the first driving member 21 and connected to the output end of the second driving member 23.

[0034] In actual use of this embodiment, the rotating member 22 is rotatably connected to the outside of the shell 1. When the first driving member 21 controls the rotating member 22 to reduce the horizontal angle between the ground and the body of the vehicle is lowered. Conversely, the height of the shell 1 can be increased by increasing the angle. The first driving member 21 is fixed on the shell 1, and can drive the rotating member 22 to rotate and hover. The second driving member 23 is fixed on the inner side of the rotating member 22 and the output end is connected to the rotating wheel 24 to drive the rotating wheel 24.

[0035] Exemplarily, the rotating member 22 can be a rotating rod or a rotating plate with openings at both ends; the first driving member 21 can be a DC reduction motor with a straight AB phase encoder, and the rotation angle can be controlled by programming, generally rotating within the range of 0-90 degrees; the second driving member 23 can be a small worm gear self-locking gear speed regulation motor, and the specification model is JYG-385; of course, the first driving member 21 and the second driving member 23 can also be servos or other types of motors, as long as they can drive the rotating wheel 24 and the rotating member 22 to rotate, this embodiment is not specifically limited here.

[0036] It should be noted that, in addition to the rotating wheel and rotating rod in this embodiment, the mobile lifting component 2 can also adopt a hydraulic rod or electric cylinder with one end fixedly connected to the shell 1 and the other end connected to the rotating wheel, so as to control the height of the entire shell 1 by adjusting the extension and contraction of the hydraulic rod or the electric cylinder; at this time, the number of mobile lifting components 2 can be selected according to needs, and they can be symmetrically distributed on both sides of the shell 1, or they can be set in an asymmetrical manner; of course, the specific number can also be selected according to needs, and this embodiment does not make any specific limitations here.

[0037] In one case of this embodiment, if Figure 3 As shown, three conveying screws 3 are evenly spaced inside the shell 1, and the front and rear ends of the shell 1 are respectively provided with two feed ports and two discharge ports.

[0038] It can be known that by providing three conveying screws 3, the conveying efficiency of table tennis balls can be increased, and the corresponding feed port and discharge port can be conveniently delivered from the inside of the shell 1 when the table tennis balls are conveyed to a preset position, and then stored in the ball collection box 4.

[0039] Example 2

[0040] like Figure 3-Figure 5 As shown, on the basis of Embodiment 1, two guide plates 8 are fixedly provided on the front end surface of the housing 1, and the two guide plates 8 are symmetrically distributed relative to the conveying screw 3 at the middle position.

[0041] In actual application, this embodiment utilizes two guide plates 8 fixed on the front end face of the shell 1 to gather the ping-pong balls in front during the movement of the shell 1, thereby transferring the ping-pong balls to the front end position of the shell 1, and then conveying the ping-pong balls to the discharge port through two adjacent conveying screws 3.

[0042] Specifically, a certain angle is formed between the two guide plates 8 and the front end surface of the shell 1 , and the distance between the two guide plates 8 gradually increases along the direction away from the shell 1 .

[0043] It is not difficult to see that an angle is set between the two guide plates 8 and the front end surface of the shell 1, and the distance between the two guide plates 8 gradually increases in the direction away from the shell 1, so that the size of the guide opening between the two guide plates 8 can be increased, making it easier to guide the table tennis ball in the front area of ​​the shell 1.

[0044] Furthermore, the driving assembly 5 includes: a driving motor 51 fixed to the top surface of the housing 1 , a driving shaft 52 connected to the output end of the driving motor 51 , and a pulley set 53 connected between the driving shaft 52 and the conveying screw 3 .

[0045] It can be known that the driving shaft 52 is driven to rotate by the driving motor 51 , and the driving shaft 52 is driven to rotate by the pulley set 53 connected between the driving shaft 52 and the conveying screw 3 .

[0046] It should be noted that, in addition to the above-mentioned drive motor 51 and pulley set 53, the conveying screw 3 may also adopt chain drive or other drive methods, as long as it can drive the conveying screw 3 to rotate, and this embodiment does not make any specific limitation here.

[0047] Example 3

[0048] like Figure 1 and Figure 3 As shown, based on Example 1 and Example 2, the detection module 6 includes: a height sensor 61 fixedly arranged at the bottom of the ball collecting box 4, and an image acquisition unit 62 arranged at the front end of the shell 1, and the image acquisition unit 62 and the height sensor 61 are both signal-connected to the control unit 7.

[0049] It can be known that, when the shell 1 moves to the preset position, the height of the shell 1 is detected by the height sensor 61, thereby transmitting the height signal to the control unit 7, and then controlling the mobile lifting component 2 to reach a suitable height, so as to lift the box body to a suitable height, so as to facilitate the conveying screw 3 to convey the table tennis ball.

[0050] Exemplarily, the image acquisition unit 62 can be a camera arranged on the front side of the shell 1, which can collect image information of the front end of the shell 1 in real time, and then transmit the image information to the control unit 8 for identification and judgment. The control unit can be a controller or a microcomputer. When the control unit 8 recognizes that there is a target object in front, it sends a signal to the mobile lifting component 2 to drive the shell 1 to move toward the target object, thereby realizing automatic picking up of the table tennis ball.

[0051] It should be noted that when the moving direction of the shell 1 needs to be controlled, the speed of the rotating wheels 24 on both sides can be adjusted and the speed difference of the rotating wheels 24 on both sides can be utilized to adjust the moving direction of the shell 1 so as to move the shell 1 to the side of the target object.

[0052] In actual operation of this embodiment, Figure 4 As shown, a notch is provided at one end of the ball collecting box 4 connected to the housing 1, and the ball collecting box 4 is hollow inside and has no top cover.

[0053] It can be known that a notch is provided on one side of the ball collecting box 4 to facilitate receiving the ping-pong balls delivered by the conveying screw 3. By setting the ball collecting box 4 to be hollow inside and without a top cover, after ensuring that the ping-pong balls are delivered to the ball collecting box 4, it is more convenient for users to take out the collected ping-pong balls from the inside of the ball collecting box 4 at any time. Therefore, during exercise, users do not need to move around to pick up balls, but only need to focus on exercise.

[0054] In one case of this embodiment, the distance between the axis of the conveying screw 3 and the bottom surface of the ball collecting box 4 is greater than the diameter of the table tennis ball, and the conveying screw 3 forms a certain angle with the horizontal ground.

[0055] It can be known that by making the distance between the axis of the conveying screw 3 and the bottom surface of the ball collecting box 4 greater than the diameter of the ping-pong ball, it is convenient for the ball collecting box 4 to smoothly receive the ping-pong balls collected by the conveying screw 3, and the conveying screw 3 forms a certain angle with the horizontal ground, which makes it more convenient at the beginning. The ball can be squeezed smoothly between the two conveying screws 3 to avoid direct contact between the conveying screw 3 and the ping-pong ball, which causes the ping-pong ball to be slipped away, thereby improving the stability and reliability of the picking process.

[0056] Exemplarily, an angle of 1-5 degrees can be set between the conveying screw 3 and the horizontal ground, so as to ensure that when the conveying screw 3 is located above the ping-pong ball, the ping-pong ball will not be squeezed out of the recovery area due to the descent of the conveying screw 3.

[0057] The above embodiment of the utility model provides an automatic table tennis ball picking device. When the user is playing table tennis and needs to pick up the ball, the control unit 7 controls the mobile lifting assembly 2 to drive the shell 1 to move. The detection module 6 detects in real time whether there is a target object in the field of view and transmits a signal to the control unit 7. When the detection module 6 finds the table tennis ball in the field of view, the control unit 7 receives the information of the detection module 6 and sends a signal to the mobile lifting assembly 2, thereby driving the shell 1 to move to the target position; in the process of the shell 1 moving forward, the table tennis ball gradually moves along the feed port between the two conveying screws 3, and then the shell 1 gradually descends to a suitable height under the action of the mobile lifting assembly 2. Under the action of the driving assembly 5, the conveying screw 3 rotates and descends, thereby wrapping the table tennis ball moved from the feed port, thereby conveying the table tennis ball along the two adjacent conveying screws 3, and finally the shell 1 is transmitted from the discharge port and put into the ball collecting box 4 located at the rear end of the shell 1, thereby completing the automatic picking up of the table tennis ball. The whole process is fully automated to ensure the picking efficiency, and the noise and volume are small, which is convenient to meet the user's use needs.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
