[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0037] The defects and shortcomings of the existing automatic ball storage and retrieval equipment are that the balls are not cleaned and checked for air leaks or other conditions that may affect their use before being stored, resulting in the ball surface being dirty and the internal air pressure being insufficient when the ball is taken out for reuse, making it impossible to use it normally.

[0038] In order to solve the above technical problems, this embodiment provides an automatic storage cabinet for balls, please refer to Figures 1 to 3 As shown, Figure 1 This is a front view of the automatic ball storage cabinet in the embodiment. Figure 2 This is a top view of the automatic ball storage cabinet in the embodiment. Figure 3 Schematic diagram of the pressure detection mechanism in the embodiment.

[0039] The automatic ball storage cabinet of this embodiment includes: a cabinet body 1, a track 2, a cleaning mechanism 3, a detection mechanism 4 and a ball discharging mechanism 5.

[0040] The cabinet 1 is provided with a goal channel 11, a ball retrieval channel 12 and a ball outlet channel 13. The goal channel 11 is used to transport the balls to be stored to the track 2, the ball retrieval channel 12 is used to output the balls to be taken out on the track 2, and the ball outlet channel 13 is used to output the balls that fail the inspection.

[0041] The track 2 is disposed in the cabinet 1 and extends from the end of the goal channel 11 to the entrance of the ball retrieval channel 12 to guide the ball rolling out of the goal channel 11 to roll to the entrance of the ball retrieval channel 12 along a preset path.

[0042] The cleaning mechanism 3 includes a brush roller 31 and a driving motor 32 for driving the brush roller 31 to rotate. The brush rollers 31 are arranged in pairs and at intervals on opposite sides of the goal channel 11. The driving motor 32 is connected to the cabinet 1.

[0043] The detection mechanism 4 includes a pressure detection mechanism arranged at the rear end of the cleaning mechanism 3. The pressure detection mechanism includes a roller 41 and a pressure sensor 42 connected to the roller 41. The rollers 41 are arranged in pairs and at intervals on opposite sides of the goal channel 11. The pressure sensor 42 is used to sense the pressure of the ball on the roller 41.

[0044] The ball discharging mechanism 5 is disposed on the cabinet 1 , and is used to convey the ball to the ball discharging channel 13 when the pressure sensor 42 senses that the pressure of the ball on the roller 41 is less than a preset value.

[0045] When the ball is stored in the automatic ball storage cabinet of the above technical solution, the ball enters the track 2 through the goal channel 11 for storage. When the ball is taken out, the ball enters the ball taking channel 12 through the track 2 for taking out. When the ball is stored, the ball passes through the cleaning mechanism 3 and the detection mechanism 4 in the goal channel 11 in sequence. The cleaning mechanism 3 drives the brush roller 31 to rotate through the driving motor 32. The ball passes between the brush rollers 31, and the brush roller 31 cleans the dust and foreign matter on the surface of the ball to reduce the dirtiness of the ball surface when the ball is used again; the cleaned ball enters the roller 41 of the pressure detection mechanism. When the ball passes through the roller 41, the pressure sensor 42 senses the pressure of the ball on the roller 41. The pressure can reflect the internal air pressure of the ball. When the pressure is less than the preset value, the ball outlet mechanism 5 transports the ball to the ball outlet channel 13 to ensure that the balls entering the track 2 are all leak-free balls, reducing the situation where the ball is used again due to unqualified internal pressure and affects normal use.

[0046] It can be seen that the automatic ball storage cabinet of the above technical solution can clean and inspect the balls, improve the cleanliness of the surface of the balls when they are used again, and reduce the situation of unqualified air pressure inside the balls, which is conducive to the normal use of the balls again.

[0047] In one embodiment of the pressure sensor 42 sensing the pressure of the ball on the roller 41, refer to Figure 1 and Figure 3As shown, first, a pressure sensor 42 is installed at a suitable position of the roller 41. The installation position of the sensor should ensure that when the ball rolls or contacts the roller 41, pressure data can be stably obtained. For example, a mounting hole for installing the pressure sensor 42 is opened on the surface of the roller 41, so that the pressure sensor 42 should be able to directly contact the ball, so as to accurately sense the pressure exerted by the ball on the roller 41; the number of pressure sensors 42 can be multiple, and they are arranged on the roller 41 at intervals in the circumferential direction. The pressure sensor 42 can be installed on only one side of the roller 41, and its line can be led outward from the hollow middle part of the roller 41 and led out through a rotating joint at the end of the roller 41 to avoid winding; the pressure sensor 42 adopts the working principle of the resistance strain type. When the ball applies pressure to the roller 41, the pressure The sensitive element (such as a resistance strain gauge) inside the force sensor 42 will deform, and the degree of deformation is proportional to the magnitude of the pressure. The deformation of the sensitive element causes the resistance value to change, and this change is captured by the circuit inside the pressure sensor 42 and converted into an electrical signal; next, the pressure sensor 42 will further process and convert this electrical signal in an existing manner, and the processed electrical signal will directly reflect the pressure of the ball on the roller 41; finally, the pressure sensor 42 outputs the processed electrical signal to the control system of the ball automatic storage cabinet. After receiving the signal, the control system will analyze and judge. If the pressure of the ball on the roller 41 is less than the preset threshold, the control system will judge the ball as an unqualified ball and trigger the ball discharging mechanism 5 to perform the discharge operation. At the same time, the control system can also record and save the pressure data for subsequent analysis and improvement.

[0048] In order to detect the appearance of the ball and determine whether the ball has deflation, cracks in the ball skin, etc., in one embodiment of the detection mechanism 4, the detection mechanism 4 also includes a visual detection mechanism disposed in the cabinet 1, see Figure 1 and Figure 2 As shown, the visual detection mechanism includes a camera 43 and an image processing unit. The camera 43 is used to photograph the ball in the goal channel 11 and at the rear end of the cleaning mechanism 3, and transmit the photo to the image processing unit. The image processing unit compares the photo with the preset normal appearance of the ball through the existing image processing algorithm, so as to detect whether its appearance meets the requirements.

[0049] For further information, see Figure 1 and Figure 2As shown, in order to detect the appearance of the ball in all directions and reduce the number of cameras 43, the visual inspection mechanism also includes a rotating table 44. The rotating table 44 is arranged in the goal channel 11 and is located at the rear end of the cleaning mechanism 3. The rotating table 44 is used to drive the ball to rotate. The visual inspection mechanism is used to photograph and detect the appearance of the ball on the rotating table 44. During operation, the ball after cleaning and internal air pressure detection enters the rotating table 44 and rotates in all directions with the rotating table 44. The camera 43 takes photos in all directions, and the image processing unit then detects each photo separately to determine whether the appearance of the ball meets the requirements in all directions.

[0050] For example, see Figure 4 As shown, Figure 4 It is a three-dimensional diagram of the rotating table in the embodiment, the rotating table 44 is composed of a base 441, a rotating motor 442 and a supporting surface 443, wherein the base 441 is fixed at an appropriate position in the goal channel 11, the rotating motor 442 is vertically installed on the base 441, and the supporting surface 443 is connected to the driving shaft of the rotating motor 442 for transmission connection to form a planar rotating platform, and the supporting surface 443 needs to have a certain friction coefficient to ensure that the ball can rotate stably on the rotating table 44 without slipping easily; when the ball passes through the cleaning mechanism 3 and the pressure detection mechanism and rolls onto the rotating table 44, the camera 43 in the visual detection mechanism starts to work, at this time, the motor drives the rotating table 44 to start rotating, driving the ball to rotate on the supporting surface 443, and the camera 43 can obtain all-round appearance information of the ball by shooting the rotating ball, and then analyze and judge it through the image processing unit.

[0051] Exemplarily, a brake block is provided in the goal channel 11, which is used to prevent the ball in the goal channel 11 from being transported forward, and when necessary, it is driven by a motor, a telescopic rod or other driving parts to rotate or move to open the goal channel 11 so that the ball continues to be transported forward.

[0052] In one embodiment of the ball outlet mechanism 5, the balls are transported to the ball outlet channel 13. Figure 1 and Figure 2 As shown, the ball outlet channel 13 is located below the goal channel 11 and is connected through an opening 14, which is located at the rear ends of the cleaning mechanism 3 and the detection mechanism 4; the ball outlet mechanism 5 includes a movable door 51 arranged at the opening 14, and the movable door 51 opens when the pressure sensor 42 senses that the pressure of the ball on the roller 41 is less than a preset value, so that the ball falls into the ball outlet channel 13 from the opening 14.

[0053] Exemplarily, the movable door 51 is an existing electric opening and closing door, such as the movable door 51 is connected to the cabinet 1 by a hinge or a slide rail, and rotates or moves under the drive of an electric telescopic rod, one end of the electric telescopic rod is connected to the movable door 51, and the other end is connected to the cabinet 1, so as to ensure that the movable door 51 can be opened and closed smoothly; the ball after cleaning and inspection rolls onto the movable door 51 under the action of its own weight or a pushing mechanism. When the ball fails the inspection, the movable door 51 opens, allowing the ball to fall into the ball outlet channel 13 below.

[0054] For example, see Figure 1 and Figure 5 As shown, Figure 5 It is a three-dimensional diagram of the lifting mechanism in the embodiment. The automatic ball storage cabinet also includes a lifting mechanism 6, which is arranged in the cabinet body 1, and includes a lifting platform 61 and a driving device 62. After the detection mechanism 4 detects that the ball is qualified, the lifting platform 61 is driven to rise and fall by the driving device 62, so as to lift the ball to the front end of the track 2. The driving device 62 can be an existing screw lifting module, which is installed on the cabinet body 1 and fixedly connected to the lifting platform 61 through the lifting end. When working, the ball that has passed the inspection can roll to the lifting platform 61 under the action of its own weight or the pushing mechanism. The lifting platform 61 has a certain inclination, so that when it is lifted to the front end of the track 2 and the opening at the upper end of the goal channel 11, the ball can automatically roll into the track 2. During the lifting process, the ball is blocked by the cabinet body 1 and will not fall from the lifting platform 61.

[0055] For example, see Figure 2 and Figure 5 As shown, the lifting platform 61 is provided with a circular groove for placing the ball.

[0056] In one implementation of the above track 2, see Figure 1 and Figure 2 As shown, the track 2 is a spiral track 2, a column 15 is provided in the cabinet 1, and the spiral track 2 is wound around the column 15. Exemplarily, the spiral track 2 is welded to the column 15, wherein the spiral track 2 can store a large number of balls and enable the balls to be transported downward under the action of their own weight.

[0057] Exemplarily, the track 2 and the ball taking channel 12 are provided with the above-mentioned brake blocks for controlling the output of the balls.

[0058] For example, see Figure 2 As shown, the spiral track 2 includes at least two spiral rods, which limit the bottom and sides of the ball.

[0059] In one embodiment of the above-mentioned goal channel 11, ball taking channel 12 and ball outlet channel 13, refer to Figure 1 and Figure 2As shown, the cabinet 1 includes a partition 16, which is fixedly connected to the inner side of the cabinet 1, and the inner space of the cabinet 1 is divided into a ball-entering channel 11, a ball-taking channel 12 and a ball-discharging channel 13 by the partition 16.

[0060] It can be understood that the brush roller 31 and the roller 41 at the front end of the goal channel 11 have the function of pushing the ball forward.

[0061] For example, see Figure 1 As shown, the goal track 2 is a downwardly inclined channel and is provided with a brake block. After the brake block is opened, the ball can roll onto the rotating table 44, the automatic door and the lifting platform 61 in sequence under the action of its own weight.

[0062] Exemplarily, a pushing mechanism is provided in the goal channel 11, which includes a push rod for pushing the ball to roll forward and a motor for driving the push rod to rotate. The push rod can exit or enter the goal channel 11 when driven by the motor, thereby pushing the ball to roll forward, and exit the goal channel 11 after being pushed, without affecting the subsequent delivery of the ball.

[0063] For example, see Figure 2 As shown, a guide port is provided at the entrance of the goal channel 11 , and the guide port is used to guide the ball into between the two brush rollers 31 .

[0064] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
