Description

Automatic pressure regulating ball center grinding equipment

The present invention relates to a grinding device, in particular to an automatic pressure-regulated ball center grinding device, which can be applied to the automated production of golf balls.

In the production process of small spheres, the spheres are first ground into a spherical shape with a higher degree of true roundness by grinding equipment. After a small batch of spheres is produced, the ground spheres are measured manually to determine whether the size meets the predetermined size. If the size of the ground spheres does not meet the predetermined size, the grinding data of the grinding equipment is manually adjusted to improve the size of the spheres produced in the subsequent process.

However, the grinding mechanism design of conventional grinding equipment is relatively simple, and it is still unable to grind out a spherical shape with a high degree of roundness. In addition, the subsequent spherical size measurement and machine adjustment must be done manually. Therefore, the production cost of the sphere has remained high.

Therefore, how to overcome the above-mentioned defects through the improvement of structural design has become one of the important issues that the technical field of the present invention wants to solve.

In view of the shortcomings of the existing technology, the present invention provides an automatic pressure-regulated ball center grinding device that can ensure the stability of golf ball performance, so as to solve the problems existing in the above-mentioned prior art.

In one embodiment of the present invention, the grinding device further includes a first driving mechanism and a second driving mechanism, wherein the first driving mechanism is configured to drive the pressure roller to rotate, and the second driving mechanism is configured to drive the pressure roller to move closer to or farther from the grinding roller.

In one embodiment of the present invention, when the average value of the outer diameter obtained by the control device based on the measurement data of the non-contact dimension measuring instrument is closer to the lower limit of the preset numerical range, under the control of the control device, the pressurizing roller is driven by the second driving mechanism to move away from the grinding roller, thereby increasing the distance between the grinding roller and the pressurizing roller.

In one embodiment of the present invention, when the average value of the outer diameter obtained by the control device based on the measurement data of the non-contact dimension measuring instrument is closer to the upper limit of the preset numerical range, under the control of the control device, the pressurizing roller is driven by the second driving mechanism to move toward the grinding roller, thereby reducing the distance between the grinding roller and the pressurizing roller.

[First embodiment]

Please refer to Figures 1 to 6, which are respectively a partial structural schematic diagram of one viewing angle of the grinding device of the automatic pressure-regulated ball center grinding device of the first embodiment of the present invention, a partial structural schematic diagram of another viewing angle of the grinding device, a schematic diagram of the operating state of the grinding device, a partial structural schematic diagram, a structural schematic diagram of the conveying device, and a functional block diagram. As shown in the above figures, the first embodiment of the present invention provides an automatic pressure-regulated ball center grinding device Z, which includes: a grinding device 1, a conveying device 2, a non-contact size measuring instrument 3 and a control device 4.

First, as shown in FIGS. 1 to 3 , the grinding device 1 of the present invention is configured to grind a plurality of ball centers B so that the plurality of ball centers B have an outer diameter H within a preset value range, wherein the grinding device 1 comprises a grinding roller 10 and a pressure roller 11 disposed opposite to each other. For example, the grinding device 1 may be a ball grinding device, and the grinding roller 10 may be a grinding roller formed by a grinding wheel or a polishing wheel, and the grinding roller 10 may have a plurality of limiting grooves 100 arranged at intervals along its long axis direction. The grinding device 1 may further include a first driving mechanism 12 and a second driving mechanism 13. The first driving mechanism 12 is configured to drive the pressure roller 11 to rotate, and the second driving mechanism 13 is configured to drive the pressure roller 11 to move closer to or farther from the grinding roller 10. The first driving mechanism 12 may be a driving motor or other types of driving devices. The first driving mechanism 12 is connected to one end of the pressure roller 11; and the second driving mechanism 13 can be movably arranged on the supporting platform 15. The second driving mechanism 13 can be a multi-axial moving platform device. The second driving mechanism 13 is used to drive the pressure roller 11 to move in the front and rear direction (i.e., close to or away from the grinding roller 10) and the left and right direction. In addition, the grinding device 1 can further include a receiving seat 14, which is arranged between the grinding roller 10 and the pressure roller 11, and the receiving seat 14 can have a plurality of oblique guide grooves 140 corresponding to the positions of the plurality of limiting grooves 100. Further, the grinding device 1 can also include a supporting platform 15 and a plurality of conveying pipes 16. The grinding roller 10, the pressure roller 11 and the second driving mechanism 13 are located on the supporting platform 15. The multiple conveying pipes 16 correspond to the multiple limiting grooves 100 of the receiving seat 14.

Next, as shown in FIG. 4 and FIG. 5 , the conveying device 2 of the present invention is configured to convey the ground multiple ball centers B to a temporary storage area along a conveying path. For example, the conveying device 2 can be a conveyor belt or other types of conveying equipment. One end (i.e., the inlet end) of the conveying device 2 is connected to the grinding device 1, and the other end (i.e., the outlet end) of the conveying device 2 corresponds to the temporary storage area; wherein, the temporary storage area can be a storage rack or other types of storage devices for storing the ground ball centers B.

Next, as shown in FIG. 4 and FIG. 5 , the non-contact dimension measuring instrument 3 of the present invention is set near the conveying path to measure the outer diameter H of the multiple ball centers B after grinding. For example, the non-contact dimension measuring instrument 3 can be a laser caliper or other types of invisible light detection devices. The non-contact dimension measuring instrument 3 can be set on the conveying device 2 and adjacent to the other end (i.e., the exit end) of the conveying device 2.

Next, as shown in FIG. 6 , the control device 4 of the present invention is electrically connected to the grinding device 1 and the non-contact dimension measuring instrument 3 to control the grinding device 1 according to the measurement data of the non-contact dimension measuring instrument 3, so that the distance between the grinding roller 10 and the pressure roller 11 increases or decreases. For example, the control device 4 can be a control device, which is used to control the action of the pressure roller 11, the first driving mechanism 12, the second driving mechanism 13 and the non-contact dimension measuring instrument 3, and can receive the detection data provided by the non-contact dimension measuring instrument 3; in addition, the control device 4 can also be electrically connected to the conveying device 2 and control the operation of the conveying device 2. The control device 4 can be arranged on the grinding device 1, or arranged at a position adjacent to the grinding device 1, but is not limited thereto.

Therefore, when the average value of the outer diameter obtained by the control device 4 based on the measurement data of the non-contact dimension measuring instrument 3 is closer to the lower limit of the preset value range, under the control of the control device 4, the pressure roller 11 is driven by the second driving mechanism 13 to move away from the grinding roller 10, thereby increasing the distance between the grinding roller 10 and the pressure roller 11. Alternatively, when the average value of the outer diameter obtained by the control device 4 based on the measurement data of the non-contact dimension measuring instrument 3 is closer to the upper limit of the preset numerical range, under the control of the control device 4, the pressurizing roller 11 is driven by the second driving mechanism 13 to move toward the grinding roller 10, thereby reducing the distance between the grinding roller 10 and the pressurizing roller 11.

For example, as shown in Figures 1 to 6, during the operation of the automatic pressure-regulated ball center grinding equipment Z of the present invention, the operator can put multiple ball centers B that have not been ground into the conveying pipe 16, and the multiple ball centers B can fall into the multiple limiting grooves 100 of the receiving seat 14 through the transmission of the multiple conveying pipes 16; and each ball center B is located between the grinding roller 10 and the pressure roller 11, and each ball center B contacts the grinding roller 10 and the pressure roller 11. It is worth noting that after the grinding process of the automatic pressure regulating ball center grinding device Z is completed or before it stops operating, the control device 4 can drive the second driving mechanism 13 to operate to drive the pressure roller 11 away from the grinding roller 10; and before the automatic pressure regulating ball center grinding device Z performs the grinding process, the control device 4 can control the second driving mechanism 13 to operate to drive the pressure roller 11 to approach the grinding roller 10.

Then, the control device 4 can control the first driving mechanism 12 to rotate, so as to drive the pressure roller 11 to rotate, and then indirectly drive the multiple ball centers B to rotate; at this time, the multiple ball centers B can be ground by the grinding roller 10 by contacting the grinding roller 10. In addition, during the grinding process of the automatic pressure regulating ball center grinding equipment Z, the control device 4 can control the second driving mechanism 13 to reciprocate left and right, so that every part of the outer edge of each ball center B can contact the grinding roller 10 and be ground by the grinding roller 10.

Next, when the control device 4 determines that the grinding process is completed (for example, calculating the grinding time, but not limited to this), the control device 4 can control the second driving mechanism 13 to operate to drive the pressure roller 11 away from the grinding roller 10; at this time, the multiple ball centers B after grinding will fall from the receiving seat 14 and be transmitted to the conveying device 2. Then, the conveying device 2 will transport the multiple ball centers B after grinding to the temporary storage area.

Among them, the outer diameter of the ground ball center B will be measured by the non-contact dimension measuring instrument 3 before it falls into the temporary storage area on the conveying path; and, after obtaining the outer diameter dimensions of one or more ball centers B, the non-contact dimension measuring instrument 3 can generate data of the outer diameter average value and provide it to the control device 4, or the non-contact dimension measuring instrument 3 can provide the outer diameter dimension data of one or more ball centers B to the control device 4, and the control device 4 can generate data of the outer diameter average value based on the outer diameter dimension data of one or more ball centers B. Next, the control device 4 determines whether the average value of the outer diameter is close to the upper limit or lower limit of the preset numerical range (e.g., between 15 mm and 40 mm). When the control device 4 determines that the average value of the outer diameter is close to the upper limit of the preset numerical range (e.g., about 40 mm), the control device 4 controls the second driving mechanism 13 to drive the pressure roller 11 closer to the grinding roller 10 (i.e., the distance between the grinding roller 10 and the pressure roller 11 is 100 mm greater than that in the previous grinding process) during the next grinding process. , the distance between the grinding roller 10 and the pressurizing roller 11 is shortened this time); and if the control device 4 determines that the average value of the outer diameter is close to the lower limit of the preset numerical range (for example, about 15 mm), during the next grinding process, the control device 4 will control the second driving mechanism 13 to drive the pressurizing roller 11 farther away from the grinding roller 10 (that is, compared with the distance between the grinding roller 10 and the pressurizing roller 11 in the previous grinding process, the distance between the grinding roller 10 and the pressurizing roller 11 is increased this time). It is worth noting that the values in the above preset range (between 15mm and 40mm) are only exemplary data. In actual application, the parameters in the preset range can be adjusted according to the manufacturer or product usage requirements.

Thus, the automatic pressure regulating ball center grinding device Z of the present invention can grind the ball into a spherical shape with a higher roundness by using the above-mentioned technical solution, utilizing the settings of the grinding device 1, the conveying device 2, the non-contact size measuring instrument 3 and the control device 4 and the mutual cooperation between the devices, and the subsequent ball size measurement and grinding equipment parameter adjustment can be fully automated without interruption, thereby greatly reducing the production cost of the ball and improving the convenience of the process.

Furthermore, the automatic pressure regulating ball center grinding device Z of the present invention may also include a conveying device 5, which is arranged between the grinding device 1 and the conveying device 2. The conveying device 5 may be a conveyor belt or other types of conveying equipment, and may be arranged to convey the multiple ball centers B after grinding to the conveying device 2.

However, the above example is only one possible implementation example and is not intended to limit the present invention.

Please refer to FIG. 7, which is a partial structural schematic diagram of the automatic pressure-regulated ball center grinding device of the second embodiment of the present invention, and please refer to FIG. 1 to FIG. 6 together. As shown in the figure, the automatic pressure-regulated ball center grinding device Z of this embodiment is substantially similar to the automatic pressure-regulated ball center grinding device Z of the above-mentioned embodiment, and therefore, the arrangement or operation of the same components will not be repeated here. The difference between the automatic pressure-regulated ball center grinding device Z of this embodiment and the automatic pressure-regulated ball center grinding device Z of the above-mentioned first embodiment is that in this embodiment, the automatic pressure-regulated ball center grinding device Z may further include a cleaning device 6, and the cleaning device 6 is configured to receive a plurality of ground ball centers B from the grinding device 1 and clean them. Furthermore, the conveying device 2 may further include a buffer component 20, and the buffer component 20 is arranged on the conveying path to buffer the multiple ball centers B that have been ground and cleaned before they are conveyed to the temporary storage area; and the non-contact size measuring instrument 3 is arranged behind the buffer component 20.

For example, as shown in FIG. 4 and FIG. 7 , the cleaning device 6 can be a cleaning device for cleaning objects and has a filtering function. The cleaning device 6 can be arranged between the grinding device 1 and the conveying device 2, or the cleaning device 6 can be arranged between the grinding device 1 and the conveying device 5. Furthermore, the conveying device 2 can be arranged to receive a plurality of ball centers B that have been ground and cleaned from the cleaning device 6 and convey them to a temporary storage area.

Furthermore, after the ball center B falls from the receiving seat 14, it can be first transferred to the cleaning device 6, and the grinding ball center B can be cleaned by the cleaning device 6. Then, the cleaned ball center B can be transferred to the conveying device 2 by the conveying device 5 to perform subsequent measurement operations and be transported to the temporary storage area.

Thus, the automatic pressure regulating ball center grinding equipment Z of the present invention can make the ball center B related data obtained by the non-contact size measuring instrument 3 and the control device 4 closer to the actual size by setting the above-mentioned cleaning device 6.

However, the above example is only one possible implementation example and is not intended to limit the present invention.
