Description

Technical Field

[0001] The present invention relates to the technical field of sports goods manufacturing, in particular to a device and method for detecting the size of a tennis ball core used in tennis ball production. Background Art

[0002] In the production and manufacturing of tennis balls, the core is a key basic component, and the accuracy of its size directly affects the performance and quality of the finished tennis ball. If the diameter of the core exceeds the standard range, it will lead to uneven elasticity and weight distribution of the tennis ball, which will in turn affect the feel of the ball, flight trajectory, etc.

[0003] For example, Chinese patent CN117732752A discloses a size detection device for tennis ball cores and a screening method thereof, which includes a screening device, which includes a feeding mechanism, a material arranging and storing mechanism, a transfer conveying mechanism, and a material discharging counting mechanism connected in sequence, and a pressure primary screening mechanism and a size screening mechanism are provided above the transfer conveying mechanism.

[0004] Currently, the most common method for detecting ball core dimensions relies on single caliper measurement or camera photography. This method can only perform simple measurements of the core diameter. It is difficult to accurately and comprehensively detect more complex but equally important dimensional parameters such as the core's roundness and concentricity. Measurement errors are prone to occur, making it impossible to effectively screen out some cores with dimensional defects, and unable to guarantee high-precision and stable test results.

[0005] Therefore, we propose a ball core size detection device for tennis ball production to solve the above problems. Summary of the Invention

A chain is arranged between the driving wheel and the driven wheel, and the outer edges of one end of the driving wheel and the driven wheel are engaged with the inner edge of the chain.

[0014] A method for detecting the size of a tennis ball core used in tennis ball production comprises the following steps: S1, the hydraulic push rod drives the baffle to move downward to one end of the conveyor belt, that is, the detection station; S2: Conveyor 1 is blocked by a baffle when transporting the tennis ball core to the inspection station. The contact measuring probe contacts the surface of the ball core and measures the corresponding thickness parameters. Simultaneously, the visual camera captures the ball core during the conveyance process. At this time, the micro electric push rod drives the movable rod and elastic suction cup 2 toward the ball core until the ball core is firmly clamped by elastic suction cups 1 and 2. S3, then the lifting cylinder drives the entire rotating assembly and the ball core to move upward, moving the ball core to the detection height, and the rotating motor drives the rotating rod and the arc plate to rotate.

Under the action of conveyor belt 1, the ball core slides along the inclined plate to conveyor belt 2, and is screened according to whether the ball core is qualified.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. Start the transmission motor.

The visual camera 28 can capture the entire picture of the ball core completely and clearly, and transmit the data to the controller 25; when the conveyor belt 12 transports the tennis ball core to the inspection station, it is blocked by the baffle 211. At this time, the controller 25 controls the micro electric push rod 243 to start, and the ball core is firmly clamped by the elastic suction cup 1 242 and the elastic suction cup 2 245. Then the lifting cylinder 22 drives the rotating assembly 23 as a whole and the ball core to move upward, moving the ball core to the inspection height. The rotating motor 234 drives the rotating rod 236 and the arc plate 237 to rotate, so that the ball core revolves and rotates at the same time.

[0021] Example 2: Reference Figure 1 - Figure 6 As shown: A ball core size detection device for tennis production, the top of the hydraulic push rod 24 is fixedly installed on the top of the support plate 21, and the bottom of the hydraulic push rod 24 is provided with a fixed plate 29, the top of the baffle 211 is fixedly installed on one end of the fixed plate 29, and a contact measuring probe 212 is fixedly connected to one side of the baffle 211, the bottom ends of the support plate 21 are fixedly installed on the top of the conveyor frame 11, conveyor belt 12 and conveyor belt 2 13 are respectively installed on the two ends of the conveyor frame 11, one end of conveyor belt 12 is engaged with a driving wheel 15, one end of conveyor belt 2 13 is engaged with a driven wheel 17, a chain 16 is provided between the driving wheel 15 and the driven wheel 17, and the outer edges of one end of the driving wheel 15 and the driven wheel 17 are engaged with the inner edge of the chain 16.

[0022] The working principle of this embodiment is as follows: the tennis ball core is transported to one end of the conveyor belt 12 through the vibrating plate. When the conveyor belt 12 transports the tennis ball core to the inspection station, it is blocked by the baffle 211. At this time, the contact measurement probe 212 contacts the surface of the core and measures the corresponding thickness parameters, which can accurately measure the relevant dimensional parameters of the core. At the same time, the contact measurement probe 212 is connected to the displacement sensor 210 to ensure that when the probe contacts the surface of the core, it can accurately convert the measured displacement data into a digital signal for transmission, and transmit the data to the controller 25.

[0023] The working principle of the present invention is as follows: the transmission motor 14 is started, and the transmission motor 14 can drive the conveyor belt 12 to transmit and the driving wheel 15 to rotate. The driving wheel 15 drives the driven wheel 17 to rotate through the chain 16, thereby driving the conveyor belt 2 13 to transmit. The transmission motor 14 can drive the conveyor belt 12 and the conveyor belt 2 13 to transmit in the same direction. The controller 25 controls the hydraulic push rod 24 to open, and the hydraulic push rod 24 drives the fixed plate 29 and the baffle 211 to move downward to one end of the conveyor belt 12, that is, the detection station. The tennis ball core is transported to one end of the conveyor belt 12 through the vibrating plate, and the conveyor belt 12 transports the tennis ball core to the conveyor belt 12. When the ball is delivered to the inspection station, it is blocked by baffle 211. At this time, contact measuring probe 212 contacts the surface of the ball core to measure the corresponding thickness parameters, which can accurately measure the relevant dimensional parameters of the ball core. At the same time, contact measuring probe 212 is connected to displacement sensor 210 to ensure that the probe can accurately convert the measured displacement data into a digital signal when it contacts the surface of the ball core, and transmit the data to controller 25. At the same time, visual camera 28 takes an image of the ball core during the conveyance process. Visual camera 28 can fully and clearly capture the entire image of the ball core and transmit the data to controller 25. The two ends of the curved plate 237 are located on both sides of the tennis ball core. At this time, the controller 25 controls the micro electric push rod 243 to be turned on (the pushing distance of the micro electric push rod 243 can be adjusted according to the diameter range of the ball core to ensure that the elastic suction cup 1 242 and the elastic suction cup 2 245 can clamp the ball core tightly). The micro electric push rod 243 drives the movable rod 244 and the elastic suction cup 2 245 to approach the ball core until the ball core is firmly clamped by the elastic suction cup 1 242 and the elastic suction cup 2 245. Then the controller 25 controls to open the lifting cylinder 22, and the lifting cylinder 22 drives the rotating assembly 23 as a whole and the ball core to move upward, and moves the ball core to the detection height. At this time, the rotating motor 234 drives the rotating rod 236 and the arc plate 237 to rotate. At the same time, the movable gear 239 rotates around the outer edge of the fixed gear 235, driving the bevel gear 1 240 to rotate, so that the bevel gear 241, the elastic suction cup 1 242, the elastic suction cup 245, the movable rod 244 and the ball core rotate, so that the ball core rotates while revolving. At this time, the laser scanning sensor 27 performs a multi-directional annular scan on the ball core, and can collect the position data of each point on the surface of the ball core (by analyzing the time, intensity and other information of the laser reflection back, accurately The laser scanning sensor 27 obtains the position data of each point on the surface of the core, and then calculates the core's diameter, roundness and other dimensional information. The laser scanning accuracy can reach the millimeter level or even higher, and can effectively capture tiny dimensional deviations. The data detected by the laser scanning sensor 27 is transmitted to the controller 25. After receiving various raw data, the data processing and analysis unit in the controller 25 uses the built-in algorithm to perform comprehensive processing and analysis, compare and integrate the data obtained by different measurement methods, calculate the core's diameter, roundness, and concentricity, and determine whether the core is qualified according to the preset dimensional standard range. The information on whether the core is qualified is displayed on the display screen of the controller 25, and a detailed inspection report is generated at the same time. The lifting cylinder 22 drives the rotating assembly 23 and the ball core to descend to their original position, the hydraulic push rod 24 drives the baffle 211 to move upward, and the micro electric push rod 243 drives the elastic suction cup 245 to release the ball core. Under the action of the conveyor belt 12, the ball core slides along the inclined plate 18 to the conveyor belt 2 13, and is screened according to whether the ball core is qualified. If the ball core is qualified, it is transported to the next production process. If the ball core is unqualified, it is sorted to the unqualified product collection area; The inspection mechanism 2 uses a contact measuring probe 212 to contact the surface of the tennis core to measure the corresponding thickness parameters and accurately measure the relevant dimensional parameters of the tennis core. The visual camera 28 captures the core and uses the laser scanning sensor 27 to perform a multi-directional annular scan of the core, thereby collecting position data of various points on the core surface. The contact measuring probe 212, the visual camera 28, and the laser scanning sensor 27 work together to comprehensively and accurately utilize laser scanning, contact measurement, and visual measurement technologies to comprehensively and accurately obtain various dimensional parameters of the tennis core. This greatly improves inspection accuracy, effectively reduces errors that may be introduced by a single measurement method, and ensures precise control of the core size. The inspection mechanism can not only inspect the conventional size (diameter) of the core, but also accurately measure roundness and concentricity, ensuring that any dimensional defects that may affect the quality of the tennis ball are not missed, thereby ensuring the overall quality of the tennis core. Furthermore, the inspection process for the tennis core is automated, and the inspection speed can be flexibly adjusted according to production needs, meeting the requirements of efficient production on modern tennis production lines and effectively improving production efficiency.
