Description

Technical Field

[0001] This application relates to the field of balance testing equipment technology, specifically a balance testing table for the production and testing of multi-channel sports balls. Background Technology

[0002] In the production process of sports balls (such as basketballs and volleyballs), balance testing is a key step in ensuring product quality. Traditional balance testing methods usually involve manual operation: releasing the ball from the midpoint of one end of the test platform, observing whether it rolls in a straight line to the midpoint of the other end, and judging whether it is qualified by the surface scale lines.

[0003] However, the high speed of the rolling balls makes it difficult for manual visual inspection to fully capture their trajectory, especially in mass production scenarios. This can easily lead to misjudgments due to missed observations. Furthermore, the use of scale markings relies on operator subjectivity and lacks objective quantitative standards, further reducing inspection reliability. After inspection, qualified and unqualified products must be manually sorted, which is inefficient and prone to mixing in defective products. Existing sorting devices mostly use fixed robotic arms or conveyor belts, which cannot dynamically adjust the sorting path based on inspection results, making it difficult to meet the needs of multi-channel and differentiated sorting. Traditional conveyor track spacing is fixed and can only accommodate balls of a single size. When inspecting balls of different sizes, such as volleyballs, soccer balls, and basketballs, manual replacement of track components is required, which is cumbersome and affects production continuity. In addition, the levelness of the testing platform relies on manual calibration; uneven ground or slight deformation caused by long-term equipment use can introduce inspection errors. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a multi-channel balance testing platform for the production and testing of sports balls, which has advantages such as automatic detection, applicability to balls of different sizes, and automatic sorting, thus solving the problems mentioned in the background technology.

[0005] To achieve the above objectives, this application provides the following technical solution: a balance test bench for the production and testing of multi-channel sports balls, comprising a test bench, a conveying mechanism and a sorting mechanism, wherein the upper surface of the test bench is provided with marking lines;

[0006] The conveying mechanism is located at one end of the test bench, and the sorting mechanism is located at the other end of the test bench.

[0007] The conveying mechanism includes two slide rails, which are arranged along the height of the test platform and are fixedly connected to one end of the test platform. A conveying box is slidably connected to one side of the two slide rails. Multiple sets of slide rods are fixedly connected between the two inner side walls of the conveying box from top to bottom. The spacing between each set of slide rails gradually decreases from top to bottom. The end of the conveying box closer to the test platform is lower than the other end.

[0008] Furthermore, a support plate is fixedly connected to one end of the bottom of the test platform, and one end of the support plate extends below the end of the conveyor box away from the support plate. An adjusting electric push rod is vertically installed on the upper surface of the support plate, and the output end of the adjusting electric push rod is fixedly connected to the conveyor box.

[0009] The above solution allows for adjustment of the height of the conveyor box, thereby ensuring that one end of the slide rails with different spacings is on the same reference plane as the upper surface of the test platform, thus ensuring a smooth transition of the sphere from the conveyor mechanism to the test platform.

[0010] Furthermore, the bottom of the test platform is provided with four leveling electric actuators arranged in a matrix and with their axes perpendicular to the test platform. Each leveling electric actuator has a support plate installed at its output end, and a level sensor is installed at the bottom center of the test platform.

[0011] The above scheme achieves automatic leveling of the test bench by setting up a leveling electric actuator and a level sensor. The level sensor and leveling electric actuator, through feedback control, keep the test bench in a level state at all times.

[0012] Furthermore, the sorting mechanism includes a material drop box, which is set along the width of the test bench and is located on one side of the test bench. A servo motor perpendicular to the test bench is installed on the side of the material drop box away from the test bench. The output end of the servo motor is fixedly connected to a linear module through a coupling. The linear module is coaxial with the servo motor. A lifting frame is slidably connected to the linear module. The lifting frame is located above the material drop box, and an electric suction cup is installed at the bottom of the lifting frame.

[0013] The above solution describes an electric suction cup as an actuator that uses electromagnetic attraction to grasp balls. It can classify and grasp balls according to their type (such as qualified and unqualified products). This is existing technology and will not be elaborated upon here.

[0014] Furthermore, guide plates are provided on both sides of the test platform, with the end of the two guide plates near the material drop box being lower than the other end.

[0015] With the above scheme, the two guide plates can catch the balls that fall to the sides when passing through the test bench and guide them into the material box at one end.

[0016] Furthermore, two rubber pads are installed on the inner bottom wall of the material box, with one end of the two rubber pads being lower than the other.

[0017] The above-mentioned design, with its inclined surface, guides the ball to the middle of the drop box, making it easier to collect the ball. At the same time, the rubber pads can cushion the falling ball and prevent it from popping out of the drop box.

[0018] Furthermore, a support rod is installed on the side of the material box away from the test platform. The support rod has an inverted L-shaped structure, and the top of the support rod is located between one end of the material box and the test platform. An industrial camera module is installed on the top of the support rod.

[0019] Through the above scheme, the industrial camera module is connected to the external control system. With the above settings, the industrial camera module can realize real-time image acquisition and defect identification of the rolling trajectory and falling state of the ball on the test platform. Qualified materials are picked up by the electric suction cup and placed in the qualified product collection area through the sorting mechanism, while unqualified materials are picked up by the electric suction cup and placed in the unqualified product collection area.

[0020] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0021] This multi-channel balance testing platform for the production and testing of sports balls features a conveyor box with adjustable height via an electric push rod. Combined with a design of multiple sets of sliding rods with progressively smaller spacing, it can accommodate balls of different diameters (such as volleyballs, soccer balls, and basketballs). When the ball rolls along the sliding rods to the testing platform, the end of the sliding rail and the upper surface of the testing platform maintain the same reference plane, ensuring a smooth transition for the ball and avoiding jamming or offset due to size differences. This significantly improves the equipment's versatility for balls of various sizes.

[0022] By using a level sensor to monitor the level of the test bench in real time, and combining it with four matrix-arranged leveling electric actuators to dynamically adjust the support height, the test bench can automatically compensate for tilt caused by uneven ground or equipment deformation, ensuring that the test bench is always level. This makes the ball's rolling trajectory only affected by its own balance, greatly improving the objectivity and reliability of the test results.

[0023] The industrial camera module acquires real-time images of the rolling trajectory of the ball on the test bench. Combined with the control system, it performs quantitative analysis on the overlap between the trajectory and the marking line, which can accurately identify the offset and determine whether it is qualified or not. This replaces the subjective judgment of traditional manual visual inspection. In the sorting mechanism, the linear module adjusts the position of the lifting frame, and the electric suction cup picks up the ball. Based on the test results, the rotation is controlled by the servo motor to control the dropping area, realizing the automation of the inspection and sorting process and avoiding the low efficiency of manual sorting and the risk of defective products being mixed in.

[0024] The guide plates on both sides of the test platform catch the balls that deviate to the sides during rolling and guide them to the drop box to prevent the balls from falling off the test platform; the inclined rubber pads inside the drop box buffer the falling balls and guide them to the middle to prevent the balls from popping out and ensure the continuity of the production process.

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0035] Please see Figures 1-4 This embodiment of a multi-channel sports ball production testing balance test bench includes a test bench 1, a conveying mechanism 2 and a sorting mechanism 3. The upper surface of the test bench 1 is provided with a marking line 101 for the reference positioning of balance testing. The balance is judged by the degree of overlap between the ball rolling path and the marking line 101.

[0036] The conveying mechanism 2 is located at one end of the test platform 1, and the sorting mechanism 3 is located at the other end of the test platform 1. The conveying mechanism 2 includes two slide rails 201, which are arranged along the height direction of the test platform 1 and are fixedly connected to one end of the test platform 1. A conveying box 202 is slidably connected to one side of the two slide rails 201. Multiple sets of slide rods 203 are fixedly connected between the two inner side walls of the conveying box 202 from top to bottom. The spacing between each set of slide rails 201 gradually decreases from top to bottom. The end of the conveying box 202 closer to the test platform 1 is lower than the other end. Through the above arrangement, the automatic adaptation of the conveying channel for balls of different sizes can be realized. The ball slides out onto the test platform 1 through the slide rods 203 and passes through the marking line 101 to determine whether the rolling trajectory of the ball meets the balance requirements.

[0037] A support plate 4 is fixedly connected to one end of the bottom of the test platform 1. One end of the support plate 4 extends to the lower end of the conveyor box 202 away from the support plate 4. An adjusting electric push rod 5 is vertically installed on the upper surface of the support plate 4. The output end of the adjusting electric push rod 5 is fixedly connected to the conveyor box 202. Through the above settings, the height of the conveyor box 202 can be adjusted, so that one end of the slide rails 201 with different spacings is on the same reference plane as the upper surface of the test platform 1, ensuring that the ball smoothly transitions from the conveying mechanism 2 to the test platform 1.

[0038] The bottom of the test bench 1 is equipped with four leveling electric actuators 6 arranged in a matrix with their axes perpendicular to the test bench 1. Each leveling electric actuator 6 has a support plate 7 installed at its output end. A level sensor 8 is installed at the middle of the bottom of the test bench 1. The level sensor 8 is a detection device used to monitor the level status of the test bench 1 in real time. The automatic leveling function of the test bench 1 is realized by setting up the leveling electric actuators 6 and the level sensor 8. The setting of the level sensor 8 and the leveling electric actuators 6 keeps the test bench 1 in a level state through feedback control.

[0039] The sorting mechanism 3 includes a material drop box 301, which is set along the width of the test bench 1 and is located on one side of the test bench 1. A servo motor 302 perpendicular to the test bench 1 is installed on the side of the material drop box 301 away from the test bench 1. The output end of the servo motor 302 is fixedly connected to a linear module 303 via a coupling. The linear module 303 is coaxially arranged with the servo motor 302. A lifting frame 304 is slidably connected to the linear module 303. The lifting frame 304 is located at the material drop box 301. Above 01, an electric suction cup 305 is installed at the bottom of the lifting frame 304. The electric suction cup 305 is an actuator that grabs balls by electromagnetic attraction force. It can classify and grab balls by type, such as qualified products and unqualified products. It is existing technology and will not be described in detail here. Guide plates 9 are provided on both sides of the test table 1. The end of the two guide plates 9 that is closer to the drop box 301 is lower than the other end. The two guide plates 9 can receive the balls that fall to the sides when passing through the test table 1 and guide them into the drop box 301 at one end.

[0040] Two rubber pads 10 are installed on the inner bottom wall of the dropping box 301. The end of the two rubber pads 10 that is close to each other is lower than the other end. Through its inclined surface, the ball can be guided to the middle of the dropping box 301, which is convenient for the ball to be collected in a concentrated manner. At the same time, the rubber pads 10 can cushion the falling ball and prevent it from jumping out of the dropping box 301. A support rod 11 is installed on the side of the dropping box 301 away from the test table 1. The support rod 11 has an inverted L-shaped structure. The top of the support rod 11 is located between the dropping box 301 and the test table 1. An industrial camera module 12 is installed on the top of the support rod 11. The industrial camera module 12 is connected to an external control system. Through the above settings, the industrial camera module 12 can realize real-time image acquisition and defect identification of the rolling trajectory and dropping status of the ball on the test table 1. Qualified materials are picked up by the electric suction cup 305 through the sorting mechanism 3 and placed in the qualified product collection area. Unqualified materials are picked up by the electric suction cup 305 and placed in the unqualified product collection area.

[0041] It should be noted that the external control system is a PLC control system. The industrial camera module transmits the detection results to the PLC control system, and the PLC controls the servo motor and electric suction cup to perform the corresponding sorting actions.

[0042] The working principle of the above embodiment is as follows: First, the level sensor 8 monitors the level of the test bench 1 in real time and feeds the data back to the control system. The four matrix-type leveling electric actuators 6 extend and retract independently according to the level deviation data, adjusting the height of the support plate 7. By dynamically compensating for uneven ground or equipment deformation, the test bench 1 is ensured to always be in an absolutely level state. The electric actuators 5 are adjusted to drive the conveyor box 202 to rise and fall along the slide rail 201, so that the end of the lowest slide bar 203 is level with the surface of the test bench 1. According to the diameter of the ball, such as volleyball / soccer / basketball, the corresponding spacing of the slide bar 203 group is selected. The ball rolls naturally along the slide bar 203 group and smoothly transitions to the surface of the test bench 1 through the end. The inclined design of the conveyor box 202 ensures that the ball is naturally loaded. Upon reaching the detection speed, the ball begins to roll along the center line of the marking line 101 on the surface of the test bench 1. The industrial camera module 12 captures the ball's trajectory. The control system calculates the maximum offset between the trajectory and the marking line 101 through an image processing algorithm. After detection, the ball continues to roll along the test bench 1 into the dropping box 301. For balls with large offsets, to prevent them from falling outside, they are guided into the dropping box 301 by the guide plate 9. The servo motor 302 drives the linear module 303 for lateral positioning, and the lifting frame 304 drives the electric suction cup 305 to descend vertically. The electric suction cup 305 accurately grabs the ball in the corresponding area. By rotating the servo motor 302 forward or backward by 90°, qualified and unqualified products are placed in different collection areas.
