DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] As shown in Figures 1-4 the drawings, it relates to a kind of detection equipment for tennis production, including bottom plate 1, vertical box 2 is fixed in the middle part of bottom plate 1 upper surface, second downcomer 3 is fixed on the top wall of vertical box 2, and vertical box 2 top is equipped with the hopper 4 of storing tennis, first downcomer 5 is fixed in the bottom of hopper 4, and the bottom end of first downcomer 5 is fixedly connected with folding pipe 6 with the top end of second downcomer 3, support assembly 7 is connected between the lower surface of hopper 4 and the upper surface of vertical box 2, servo motor 9 is fixed on the upper surface of vertical box 2 near second downcomer 3, and the output shaft of servo motor 9 is fixedly connected with baffle 10 by passing through the top wall of vertical box 2, and the output shaft of servo motor 9 is rotatably connected with the top wall of vertical box 2 by bearing, the upper surface of baffle 10 is pasted with the bottom end of second downcomer 3, a group of infrared light screens 12 are installed in the middle part of vertical box 2 two sides, side mouth 101 is formed in the bottom end of vertical box 2 two sides, two material receiving assemblies 13 are installed on the upper surface of bottom plate 1 two sides and near side mouth 101, and PLC controller 14 is installed on the outer wall of vertical box 2.

[0024] In the embodiment, the model of PLC controller 14 adopts programmable Mitsubishi FX1N controller, and each electronic component of the equipment is controlled to operate by PLC controller 14.

[0025] The baffle plate 10 is a circular plate, and a plurality of circular holes 11 for passing the tennis balls are equidistantly arranged on the side edges of the baffle plate 10. The servo motor 9 is electrically connected with the PLC controller 14.

[0026] The servo motor 9 can be controlled by the PLC controller 14 to drive the baffle plate 10 to rotate by a specified angle each time. When the circular hole 11 on the baffle plate 10 is aligned with the second feeding pipe 3, the tennis ball can fall along the second feeding pipe 3.

[0027] The support assembly 7 includes a vertical rod 71 fixed to the upper surface of the vertical box 2, and the top end of the vertical rod 71 is fixedly connected with a top plate 72. The top end of the top plate 72 is fixedly connected with a spring 73, and the top end of the spring 73 is fixedly connected with the lower surface of the hopper 4. The outer side wall of the hopper 4 is fixedly installed with a vibration motor 8, and the vibration motor 8 is electrically connected with the PLC controller 14.

[0028] In this embodiment, when the hopper 4 stores the tennis balls, the tennis ball at the lowermost part of the hopper 4 enters the first feeding pipe 5, and then enters the inside of the second feeding pipe 3 through the folding pipe 6. Since the hopper 4 is supported by the vertical rod 71 and the spring 73, the hopper 4 has a space for jumping up and down. Therefore, during the operation of the device, the vibration motor 8 can be intermittently started by the PLC controller 14 to drive the hopper 4 to vibrate, so as to avoid the tennis ball from being blocked at the top of the first feeding pipe 5 during the falling process.

[0029] The height of the infrared light screen 12 is the standard height of the tennis ball rebound, and the infrared light screen 12 is electrically connected with the PLC controller 14.

[0030] In this embodiment, the model of the infrared light screen 12 is WECO-917A61-AC220 infrared sensor. The infrared light screen 12 detects whether there is a tennis ball passing through. When the tennis ball passes through a group of infrared light screens 12, the light of the infrared light screen 12 is blocked, and the blocked signal is fed back to the PLC controller 14. Therefore, when detecting the elasticity of the tennis ball, the tennis ball must pass through the infrared light screen 12 once, and when the tennis ball rebounds beyond the height of the infrared light screen 12, the light of the infrared light screen 12 will be blocked again. If the tennis ball does not rebound beyond the infrared light screen 12, the infrared light screen 12 detects the blocked signal only once. Therefore, it is known that the tennis ball falls each time the baffle plate 10 rotates once. In the subsequent detection, if the infrared light screen 12 has two blocked signals, it means that the elasticity of the falling tennis ball meets the standard, and if the infrared light screen 12 has only one blocked signal, it means that the elasticity of the falling tennis ball does not meet the standard.

[0031] The material collecting assembly 13 comprises an electric telescopic rod 131 fixed to the upper surface of the bottom plate 1, and a material collecting box 132 is fixed to the telescopic end of the electric telescopic rod 131, the material collecting box 132 is located close to the side opening 101, and the electric telescopic rod 131 is electrically connected with the PLC controller 14.

[0032] The PLC controller 14 can control the telescopic rod 131 of any one of the two material collecting assemblies 13 to extend, when the first electric telescopic rod 131 is extended to drive the corresponding material collecting box 132 to move, the material collecting box 132 will pass through the side opening 101 to enter the bottom of the vertical box 2, and the material collecting box 132 can catch the tennis ball to realize automatic collection of the tennis ball. The two material collecting boxes 132 can collect the qualified and unqualified tennis balls respectively.

[0033] The bottom of the material collecting box 132 is designed as a hollow structure, and a net 133 is fixed to the bottom of the material collecting box 132. The net 133 can release the force of the falling tennis ball to avoid the tennis ball bouncing again.

[0034] Working principle: first, pour the tennis balls into the hopper 4, and then control the equipment to run through the PLC controller 14. Before each time of controlling the servo motor 9 to rotate, the PLC controller 14 first controls the vibration motor 8 to start, so that the hopper 4 vibrates to avoid the tennis balls being blocked at the top of the first discharging pipe 5, then controls the servo motor 9 to drive the baffle 10 to rotate by a specified angle, when the circular hole 11 on the baffle 10 coincides with the second discharging pipe 3, the tennis ball falls through the circular hole 11, and as the baffle 10 continues to rotate, the closed position between the adjacent two circular holes 11 continues to block the second discharging pipe 3 below, so that only one tennis ball falls each time. The tennis ball bounces after falling on the upper surface of the bottom plate 1, if the bouncing height exceeds the infrared light screen 12 (the infrared light screen 12 detects the blocking on both sides), it means that the tennis ball is qualified in elasticity, if the bouncing height does not exceed the infrared light screen 12 (the infrared light screen 12 only detects the blocking once), it means that the tennis ball is unqualified in elasticity, after the PLC controller 14 receives the qualified or unqualified information, the corresponding electric telescopic rod 131 is started to extend to drive the material collecting box 132 to move to the bottom end inside the vertical box 2 to catch the repeatedly bouncing tennis ball, then the electric telescopic rod 131 is shortened to reset, and the next detection is prepared.

The preferred embodiments do not describe all the details, and the utility model is not limited to the specific implementation. Obviously, according to the content of the specification, many modifications and changes can be made.
