Description

Technical Field

[0001] This utility model belongs to the field of data processing technology, and in particular relates to an automatic sphere counting device. Background Technology

[0002] As a fundamental metrological method, ball counting technology has crucial application value in multiple fields such as industrial production, sports training, and precision metrology. Specifically, in industrial manufacturing, accurate counting during the production of precision steel balls is essential for ensuring product quality consistency and achieving standardized packaging. In sports training, accurate counting of training balls provides a reliable basis for scientifically quantifying athletes' training load and evaluating technical performance. In metrological calibration, accurate counting of standard balls is fundamental for the traceability and precision calibration of various testing instruments. Of particular note is the fact that when using rubber balls to clean condensers in power plants, the precise control of the number of rubber balls directly affects the cleaning effect: insufficient numbers can lead to incomplete cleaning of some pipes, while excessive numbers may cause pipe blockages and accelerate pipe wall wear.

[0003] Currently, commonly used sphere counting methods can be broadly categorized into manual counting and tool counting. Traditional manual counting methods have significant limitations, including but not limited to: low counting efficiency, susceptibility to visual fatigue errors, and difficulty in achieving continuous operation. In contrast, tool counting technology, through the design of specialized sphere storage containers and outlet channels, achieves automated sphere measurement, offering clear advantages in counting efficiency and consistency. However, existing counting devices still have some shortcomings in practical use: Firstly, because the spheres are randomly stacked in the storage container, blockages easily occur at the connection between the outlet channel and the outlet container, causing interruptions in sphere movement and affecting the continuity of counting; secondly, multiple spheres may be discharged from the outlet channel simultaneously, causing counting errors and affecting the reliability and accuracy of the counting device in practical applications; thirdly, it is not applicable to counting spheres of different sizes, exhibiting poor applicability.

[0004] Therefore, there is an urgent need for an automatic sphere counting device to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic ball counting device that can be used to count balls of different specifications, ensuring the continuity of counting and the number of balls passing through the counter surface each time, thereby improving the efficiency and accuracy of counting.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] An automatic sphere counting device is provided, comprising:

[0008] The support has a ball outlet and a ball storage space connected to the ball outlet, and the ball can be stored in the ball storage space;

[0009] Multiple ball-limiting components are detachably connected to the support, and the ball-limiting components are rotatably disposed within the ball storage space. Each ball-limiting component is provided with multiple ball-limiting grooves arranged at intervals along its circumference. Any ball located in the ball storage space can be embedded in a ball-limiting groove, and the diameters of the ball-limiting grooves of the multiple ball-limiting components are different. The ball-limiting grooves have a ball-exit position located at the ball outlet and a limiting position located away from the ball outlet. In the ball-exit position, the ball-limiting groove is connected to the ball outlet, and the ball can detach from the ball-limiting groove and move out of the ball storage space through the ball outlet. In the limiting position, the ball can be confined within the ball-limiting groove by the support.

[0010] A counter, mounted on a bracket and located within the ball storage space, drives the ball limiting component to rotate. The balls embedded in the ball limiting groove can pass through the counter and then move to the ball outlet under the influence of the ball limiting component. The counter is configured to count the number of balls passing through its surface.

[0011] Optionally, the counter includes a counting body and a pressing part movably disposed on the counting body. The ball passing through the counter can contact the pressing part and press the pressing part. The counting body is configured to count the number of times the pressing part is pressed.

[0012] Alternatively, the counter includes a counting body and a laser emitting part disposed on the counting body. The laser emitting part is used to emit laser light. A sphere passing through the counter can block the laser light emitted by the laser emitting part. The counting body is configured to count the number of times the laser light is blocked.

[0013] Optionally, the ball-limiting groove is located at the edge of the ball-limiting member, and the height of the upper surface of the ball-limiting member gradually increases from the edge to the center.

[0014] Optionally, the automatic ball counting device also includes a rotary drive component mounted on the bracket, the output end of which can be connected to the ball limiter component to drive the ball limiter component to rotate.

[0015] Optionally, the automatic ball counting device also includes a power supply unit mounted on the bracket, which is electrically connected to both the rotary drive and the counter, and is configured to supply power to the rotary drive and the counter.

[0016] Optionally, the bracket is equipped with a rotatable transmission component, which is detachably connected to the ball limiting component. The output end of the rotary drive component is connected to the transmission component to drive the transmission component to rotate the ball limiting component.

[0017] Optionally, one of the ball limiting component and the transmission component is provided with a slot, and the other of the ball limiting component and the transmission component is provided with a snap-fit ​​part, which can snap into or out of the slot.

[0018] Optionally, the automatic ball counting device also includes a ball outlet channel disposed on the bracket, the ball outlet channel being located at the ball outlet, and the height of the end of the ball outlet channel near the ball outlet being higher than the height of the end of the ball outlet channel away from the ball outlet.

[0019] Optionally, the automatic ball counting device also includes an operation button, which is mounted on the bracket and electrically connected to the ball limiting component, for controlling the rotation direction and speed of the ball limiting component.

[0020] Optionally, the support includes a connected guide section and a main body. The main body is provided with an observation port whose width is smaller than the diameter of the ball. The guide section is located above the main body. The ball storage space is formed by the guide section and the main body. The guide section is provided with a ball inlet, and the side wall of the guide section is vertically inclined. The ball that enters the ball storage space through the ball inlet can move along the side wall of the guide section.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] This invention provides an automatic ball counting device. A ball-limiting component is provided with multiple ball-limiting grooves, each capable of holding a ball. When the ball-limiting groove is in its limiting position, the groove wall, together with the support, encloses the ball, constraining its position within the storage space. This ensures the balls are stored regularly, effectively preventing random accumulation. When the ball-limiting component is rotated, it moves the balls embedded in the grooves circumferentially. Driven by the ball-limiting component, the balls pass sequentially and orderly across the counter surface, ensuring not only continuous counting and improved efficiency but also accurate counting by ensuring the number of balls passing each time. When the ball-limiting groove moves to the ball outlet, the balls inside the groove are no longer constrained by the support and can detach from the groove, moving out of the storage space to prevent the counter from counting repeatedly and further improving counting accuracy. Moreover, once a counted ball has detached from the groove, other balls can fit into empty grooves, ensuring continuous counting. The ball-limiting components are detachably connected to the support, and the groove diameters of multiple components are different. Therefore, when the recorded ball diameter changes, the operator can remove the ball-limiting components from the support and install a component with a groove diameter matching the ball diameter onto the support, ensuring that balls of different sizes can fit into the grooves, thus expanding the versatility of the automatic ball counting device provided by this invention.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0036] It should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] like Figures 1 to 6 As shown, this embodiment provides an automatic sphere counting device that is applicable to counting spheres of different specifications, ensuring the continuity of counting and the number of spheres passing through the surface of counter 3 each time, thereby improving the efficiency and accuracy of counting.

[0039] See Figure 1 and Figure 2 The automatic ball counting device includes a support 1, ball limiting components 2, and a counter 3. The support 1 is provided with a ball outlet 121 and a ball storage space 13 communicating with the ball outlet 121, in which balls can be stored. Multiple ball limiting components 2 can be selectively and detachably connected to the support 1, and the ball limiting components 2 are rotatably disposed in the ball storage space 13. Multiple ball limiting grooves 21 are provided on the ball limiting components 2, which are arranged at intervals along their circumference. Any ball located in the ball storage space 13 can be embedded in a ball limiting groove 21, and the diameters of the ball limiting grooves 21 of the multiple ball limiting components 2 are different. The ball limiting grooves 21 have a position at the outlet. The ball exit position at the ball outlet 121 and the limiting position away from the ball outlet 121. When the ball exits, the ball limiting groove 21 is connected to the ball outlet 121, and the ball can leave the ball limiting groove 21 and move out of the ball storage space 13 through the ball outlet 121. When the ball is in the limiting position, the ball can be limited by the bracket 1 to be in the ball limiting groove 21. The counter 3 is set on the bracket 1 and located in the ball storage space 13, driving the ball limiting member 2 to rotate. The ball embedded in the ball limiting groove 21 can move to the ball outlet 121 after passing through the counter 3 under the drive of the ball limiting member 2. The counter 3 is configured to count the number of balls passing through its surface.

[0040] The automatic ball counting device provided in this embodiment has multiple ball-limiting grooves 21 on the ball-limiting component 2. Each ball-limiting groove 21 can embed a ball. When the ball-limiting groove 21 is in the limiting position, the groove wall of the ball-limiting groove 21 can surround the ball together with the support 1, constraining the position of the ball in the ball storage space 13, so that the balls in the ball storage space 13 can be stored regularly, effectively avoiding the occurrence of random accumulation of balls. When the ball-limiting component 2 is driven to rotate, the ball-limiting component 2 can drive the balls embedded in the ball-limiting grooves 21 to move along the circumference of the ball-limiting component 2. Under the drive of the ball-limiting component 2, the balls can pass through the surface of the counter 3 sequentially and orderly, thereby not only ensuring the continuity of counting of the counter 3 and improving the counting efficiency, but also ensuring the number of balls passing through the surface of the counter 3 each time, significantly improving the counting accuracy. When the ball-limiting groove 21 moves to the ball outlet 121, the ball located in the ball-limiting groove 21 is no longer constrained by the support 1 and can detach from the ball-limiting groove 21. The ball moves out of the ball storage space 13 to prevent the counter 3 from counting repeatedly, which helps to further improve the counting accuracy. Moreover, after the counted ball detaches from the ball-limiting groove 21, other balls can be inserted into the ball-limiting groove 21 without balls, further ensuring the continuity of counting. The ball-limiting component 2 is detachably connected to the support 1, and the diameters of the ball-limiting grooves 21 of multiple ball-limiting components 2 are different. Therefore, when the recorded ball diameter changes, the operator can remove the ball-limiting component 2 from the support 1 and install a ball-limiting component 2 with a ball-limiting groove diameter that matches the ball diameter onto the support 1 to ensure that balls of different sizes can be inserted into the ball-limiting groove 21, thus expanding the versatility of the automatic ball counting device provided in this embodiment.

[0041] In this embodiment, the diameter of the ball-limiting groove 21 is larger than the diameter of the sphere but less than twice the diameter of the sphere, so that only one sphere can be embedded in each ball-limiting groove 21.

[0042] For example, the diameter of the sphere is 25 mm and the diameter of the sphere groove 21 is 28 mm.

[0043] See Figure 2 The position of the ball limiting component 2 drives it to rotate clockwise. That is, during the rotation of the ball limiting component 2, the ball outlet 121 is located downstream of the counter 3, so that the ball can pass through the counter 3 first and then move to the ball outlet 121.

[0044] In an optional embodiment, see [link to relevant documentation] Figure 2 The counter 3 includes a counting body 31 and a pressing part 32 movably disposed on the counting body 31. A ball passing through the counter 3 can contact and press the pressing part 32. The counting body 31 is configured to count the number of times the pressing part 32 is pressed. The number of presses counted by the counting body 31 is the number of balls, making operation convenient and quick, and providing accurate statistical results.

[0045] For example, counter 3 is selected as a push-button type counter 3.

[0046] In another optional embodiment, the counter 3 includes a counting body 31 and a laser emitting unit disposed on the counting body 31. The laser emitting unit is used to emit laser light. Spheres passing through the counter 3 can block the laser light emitted by the laser emitting unit. The counting body 31 is configured to count the number of times the laser light is blocked. The number of blocking times counted by the counting body 31 is the number of spheres, which is not only convenient and quick to operate, but also provides accurate statistical results.

[0047] For example, counter 3 uses a laser probe.

[0048] Optionally, see Figure 1 and Figure 2 The ball-limiting groove 21 is located at the edge of the ball-limiting member 2, and the height of the upper surface of the ball-limiting member 2 gradually increases from the edge to the center. This arrangement allows the balls in the ball storage space 13 to move along the upper surface of the ball-limiting member 2 from the center to the edge of the ball-limiting member 2 under the action of gravity, thereby automatically embedding them into the ball-limiting groove 21 located at the edge of the ball-limiting member 2. This achieves automatic replenishment of the balls into the ball-limiting groove 21 and effectively prevents the accumulation of balls in the ball storage space 13.

[0049] For example, the ball 2 is a cone with a cone surface tilt angle of 5°.

[0050] Optionally, see Figure 2 and Figure 3 The automatic ball counting device also includes a rotary drive 4 mounted on the bracket 1. The output end of the rotary drive 4 can be connected to the ball limiter 2 to drive the ball limiter 2 to rotate, thereby improving the automation of counting.

[0051] For example, the rotary drive 4 is a motor.

[0052] Specifically, see Figure 2 , Figure 3 and Figure 4 The bracket 1 is provided with a first mounting position 122, which is located below the ball limiting member 2. The rotation drive member 4 is installed in the first mounting position 122 to drive the ball limiting member 2 to rotate.

[0053] In this embodiment, the automatic ball counting device also includes a power supply unit disposed on the support 1. The power supply unit is electrically connected to both the rotary drive unit 4 and the counter 3, and is configured to supply power to both the rotary drive unit 4 and the counter 3. This configuration allows for simultaneous power supply to both the rotary drive unit 4 and the counter 3 using only one power supply unit, significantly reducing the number of power supply units required and lowering the operating cost of the automatic ball counting device. Moreover, the power supply unit enables autonomous power supply within the automatic ball counting device, allowing the ball counting process to proceed independently, thus preventing unforeseen circumstances from affecting the counting results.

[0054] For example, the power supply unit uses a 12V lithium battery. 12V lithium batteries have advantages such as high energy density, long lifespan, and environmental friendliness, and are widely used in various fields. A charging port is provided on the bracket 1, allowing the user to charge the power supply unit.

[0055] Specifically, see Figure 2 and Figure 4 The bracket 1 is provided with a second mounting position 123, which is located below the ball limiting member 2. The power supply member is installed in the second mounting position 123 to reduce the distance between the power supply member and the ball limiting member 2 and the rotary drive member 4, so as to realize the power supply member to quickly supply power to the rotary drive member 4 and the counter 3, thereby reducing the manufacturing cost of the automatic ball counting device.

[0056] In this embodiment, a rotatable transmission component is provided on the bracket 1. The transmission component is detachably connected to the ball-limiting component 2. The output end of the rotary drive component 4 is connected to the transmission component and is used to drive the transmission component to rotate the ball-limiting component 2. This arrangement allows the ball-limiting component 2 to be detachably connected to the bracket 1 via the transmission component and also to be driven to rotate by the rotary drive component 4.

[0057] Specifically, one of the ball-limiting component 2 and the transmission component is provided with a slot, and the other of the ball-limiting component 2 and the transmission component is provided with a locking part, which can engage or disengage from the slot. When the locking part engages into the slot, the ball-limiting component 2 can be stably connected to the transmission component; when the locking part disengages from the slot, the ball-limiting component 2 separates from the transmission component, allowing for replacement of the ball-limiting component 2. The operation is convenient and quick, and easy for operators to use.

[0058] For example, the transmission component is a transmission shaft, the locking part is located at the end of the transmission shaft, and the locking groove is provided on the ball limiting member 2, so that the end of the transmission shaft can be locked into the locking groove. Furthermore, a bearing is provided on the transmission shaft to enable the transmission shaft to rotate stably.

[0059] Optionally, see Figure 1The automatic ball counting device also includes a ball outlet channel 5 installed on the support 1. The ball outlet channel 5 is located at the ball outlet 121, and the height of the end of the ball outlet channel 5 closer to the ball outlet 121 is higher than the height of the end of the ball outlet channel 5 furthest from the ball outlet 121. The ball outlet channel 5 allows the balls coming out of the ball outlet 121 to move quickly along the ball outlet channel 5, preventing the balls from accumulating at the ball outlet 121, and also helps staff to quickly collect and manage the counted balls.

[0060] Specifically, see Figure 1 The automatic ball counting device also includes a guide plate 51 set on the bracket 1 and baffles 52 set on both sides of the guide plate 51. The ball outlet channel 5 is formed by the guide plate 51 and the two baffles 52. The baffles 52 on both sides can constrain the movement direction of the ball, so that the ball only moves along the extension direction of the guide plate 51, so as to facilitate the recycling and management of the ball.

[0061] For example, the tilt angle of the ball outlet channel 5 is 10°.

[0062] Optionally, see Figure 1 , Figure 2 and Figure 6 The automatic ball counting device also includes an operation button 124, which is located on the bracket 1 and electrically connected to the ball limiting component 2. The operation button 124 controls the rotation direction and speed of the ball limiting component 2. When a ball becomes blocked in the ball storage space 13, the balls in the space can be moved by adjusting the rotation direction and speed of the ball limiting component 2, thereby loosening the blocked balls and relieving the blockage. The operation is simple and quick, facilitating use and maintenance by staff. The operation button 124 significantly improves the ease of use of the automatic ball counting device and the user experience for staff.

[0063] Optionally, see Figure 1The support 1 includes a connected guide section 11 and a main body 12. The main body 12 has an observation port 125, the width of which is smaller than the diameter of the sphere. The guide section 11 is located above the main body 12. The ball storage space 13 is formed by the guide section 11 and the main body 12. The guide section 11 has a ball inlet, and its sidewalls are vertically inclined. Spheres entering the ball storage space 13 through the ball inlet can move along the sidewalls of the guide section 11. Workers can observe the status of multiple spheres in the ball storage space 13 through the observation port 125, allowing for timely adjustments when spheres are piling up or the number of spheres is too low. The width of the observation port 125 is smaller than the diameter of the sphere, ensuring that spheres in the ball storage space 13 cannot leak out of the observation port 125, but can only leave the ball storage space 13 through the ball outlet 121, thus ensuring the accuracy of the count. When the number of balls in the ball storage space 13 is small, the staff can add balls to the ball storage space 13 through the ball inlet; the balls entering the ball storage space 13 can move under the guidance of the side wall of the guide part 11, which helps to constrain the direction of the ball movement, so that the balls can move more accurately to the ball limiting groove 21 and reduce the possibility of the balls piling up in the ball storage space 13.

[0064] For example, the guide portion 11 is a funnel, and the width of the upper end of the guide portion 11 is greater than the width of the lower end.

[0065] The above description is only a specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Those skilled in the art should understand that any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model fall within the protection and disclosure scope of the present utility model.
