The above objects and advantages of the present invention will be readily understood from the following detailed description of the preferred embodiments illustrated herein.

The invention will be described in detail in the following examples in conjunction with the drawings:

As shown in the first and second figures, the present invention is a ball automatic testing device, comprising: a base 10 having a guide portion 11; a sliding platform 20 slidably disposed thereon The servo motor 30 is internally provided with a rotary encoder 31 for driving the sliding platform 20 on the guide rod portion 11 for lifting and lowering, and the rotary encoder 31 is For measuring the displacement of the sliding platform 20; a compression measuring portion 41 is disposed on the base 10; a weight measuring portion 42 is disposed on the base 10 and located at the compression amount Below the measuring portion 42; further, the compression measuring portion 41 and the weight measuring portion 42 have a predetermined distance, and the sliding platform 20 slides between the compression measuring portion 41 and the weight measuring portion 42 A support base 50 is sleeved on the weight measuring portion 42 for placing a ball 70; a control system 60 for controlling the actuation of the servo motor 30 and analyzing The signal measured by the rotary encoder 31, the compression measuring unit 41, and the weight measuring unit 42 is converted into the displacement of the sliding platform 20, the weight of the spherical body 70, and the compressibility of the spherical body 70; As shown in the figure, the guide portion 11 includes a pair of guide bars 111 having a nut 21 and a pair of linear bearings 22, and the servo motor 30 has a ball screw 32. The ball screw 32 is screwed onto the nut 21, and when the servo motor 30 is driven, the ball screw 32 and the nut 21 can convert the rotary motion of the servo motor 30 into a linear motion, so that the sliding platform 20 linear lifting; the pair of linear bearings 22 are slidably sleeved on the pair of guiding rods 111.

The number of the guide rods 111 corresponds to the linear bearing 22, and a pair is provided to increase the stability of the linear motion. Of course, the number can also be set to four or other numbers; in addition, the function of the linear bearing 22 is used. To increase the stability of the nut 21 when moving linearly.

In more detail, the compression measuring unit 41 and the weight measuring unit 42 may be general load cells. For example, the compression measuring unit 41 is a JINSENSE LRM-100 cylindrical pressure load element, and the weight measuring unit 42 is JINSENSE LDB-2 single point beam type pressure load element.

The compression measuring portion 41 is connected to an upper pressing plate 411, and the weight measuring portion 42 is connected to a fixing rod 421 (as shown in the second figure); the supporting base 50 has a concave portion 51 for being sleeved on the The fixing rod 421 is on. When the upper pressing plate 411 or the fixing rod 421 is pressed by the force, the compression measuring portion 41 and the weight measuring portion 42 respectively perform pressure sensing on the urging force.

Regarding the operation flow of the present invention, please refer to the third to sixth figures; in the detection, the invention is described by detecting a golf ball: as shown in the third figure, it is the initial state of the invention. The sliding platform 20 is located at a first position P1 and is not in contact with the supporting base 50. At this time, the supporting base 50 is sleeved on the fixing rod 421 of the weight sensor 42 and is fixed with the fixing rod 421. The top surface is in contact; firstly, the weight of the ball 70 (ie, golf ball) is measured, and after the ball 70 is placed on the support base 50, the weight can be reduced from below. The sensing portion 42 measures the weight of the golf ball; since the weight sensing portion 42 that senses the weight below is only subjected to the weight of the golf ball by the support base 50, the weight of the support base 50 is measured before use. After correction, the weight of the golf ball can be measured.

As shown in the fourth figure, after the weight measurement of the ball 70 is completed, the sliding platform 20 starts to slowly rise to a second position P2 and is in contact with the support base 50 (the support base 50 is still maintained with the fixed rod at this time). The top surface of 421 is in contact with).

The sliding platform 20 drives the support base 50 to continue to rise, ready for compression pound measurement; as shown in the fifth figure, the sliding platform 20 rises to a third position P3, and drives the support base 50 to raise the ball 70. The pressure plate 411 is contacted with the compression measuring portion 41. At this time, the support base 50 has come out of contact with the top surface of the fixing rod 421.

As shown in the sixth figure, when the ball 70 contacts the pressing plate 411 of the compression measuring portion 41, the sliding platform 20 continues to move upward; the sphere is obtained by sensing by the compression measuring portion 41. 70 is pushed to press the pressure of the upper platen 411, records the deformation amount of 30 pounds, and then continues to press upward, and records the deformation amount reaching 200 pounds, and then substitutes the following formula to complete the compression pound measurement.

Compressibility (in) = 160 - (1000x deformation)

After the compression pound is measured, the sliding platform 20 is lowered to the initial state (that is, the first position P1) to be detached from the support base 50, and the support base 50 is returned to contact with the top surface of the fixed rod 421. The position (that is, the state of returning to the fourth figure).

Regarding golf balls, they must undergo rigorous inspection before leaving the factory, including the weight, diameter and compression pounds of the golf ball.

The present invention measures the diameter by measuring the rotary encoder 31 inside the servo motor 30 without using an optical scale or a laser caliper, which saves cost. First, the distance l ₀ between the top surface of the support base 50 and the upper pressing plate 411 must be recorded when the initial state is recorded. When the sliding platform 20 is raised to drive the support base 50 to move to contact the upper pressing plate 411, the golf ball The compression sensing unit 41 starts to sense the change in power, and the current of the servo motor 30 also starts to increase rapidly (the two characteristics can be used to judge the position where the ball is not subjected to compression deformation), and the displacement at this time is recorded as l ₁ (due to In the initial state, the sliding platform 20 has a distance from the supporting base 50 and is not in contact with each other. Therefore, l ₁ is the rising displacement distance of the sliding platform 20 minus the distance between the sliding platform 20 and the supporting base 50 when the initial state is changed. Finally, subtracting l ₁ from l _{0 is} the diameter of the golf ball; of course, the amount of deformation at 30 lb and 200 lb is also measured by the rotary encoder 31. This avoids the use of optical rulers or laser calipers, which can significantly reduce costs.

When the diameter, weight and compression pounds were measured, a golf ball test was completed.

In order to make the measurement fast and accurate, motion control, including acceleration and deceleration trajectory planning, must be performed to reduce the vibration of the machine and improve the measurement accuracy. The controller is designed to meet the requirements of control specifications such as response time, settling time, and overshoot.

The control system 60 can be a human-machine interface on a general machine. The software (for example, LabVIEW, VB, or a human-machine-specific program) is used to write a human-machine interface programming program for instrument control, experimental measurement, and results. analysis.
