Description

Technical Field

[0001] The utility model relates to the technical field of glass processing equipment, in particular to a pneumatic automatic compensation feeding grinding wheel. Background Art

[0002] In the process of glass edge grinding by the glass edge grinding machine, the glass is generally transported to the workbench one by one, and the grinding wheels installed on both sides of the workbench rotate continuously to grind the transported glass, thereby continuously completing the edging operation of multiple pieces of glass.

[0003] During the glass edging process, the drive mechanism (usually a cylinder) applies a certain amount of flexible force to the grinding wheel, causing the grinding wheel to contact the edge of the glass and complete the grinding operation. After completing the grinding process of a piece of glass, it is necessary to replace it with another piece of glass. At this time, the grinding wheel needs to be fixed in its original position and wait for the next piece of glass to be in place before continuing to apply the forward flexible force to the grinding wheel. A common practice in the prior art is to set a limit structure at the output end or other position of the drive mechanism, and set a limit point according to the feed amount of the grinding wheel. When the limit point is reached, the grinding wheel cannot continue to feed under the action of the limit structure, thereby achieving the fixing effect of the grinding wheel during the glass replacement process.

[0004] However, this design method has the following defects and shortcomings: in the process of continuously processing multiple pieces of glass, the grinding wheel will inevitably wear out, resulting in the grinding wheel being unable to make good contact with the glass, thereby affecting the processing accuracy of subsequent glass. At this time, the traditional glass edge grinding machine requires the operator to manually adjust the position of the limiting structure to allow the grinding wheel to move forward a certain displacement for distance compensation, thereby ensuring the grinding effect of the grinding wheel on subsequent glass. This operation method requires the operator to continuously manually adjust the limiting structure to compensate for the distance according to the amount of wear of the grinding wheel. The operation is cumbersome and prone to errors. At the same time, the operator often needs to adjust and compensate the position of the limiting structure only after the glass has a poor edging effect, which has a certain hysteresis, further reducing the processing accuracy of the glass.

[0005] Therefore, the prior art urgently needs to invent a grinding wheel mechanism with an automatic compensation function during the continuous glass processing process. Utility Model Content

[0006] In order to overcome at least one of the defects of the prior art described above, the present invention provides a pneumatic automatic compensating feed grinding wheel, which has the characteristic of automatic compensation function during the continuous glass processing process.

[0007] The technical solution adopted by the present invention to solve the problem is:

[0008] Pneumatic automatic compensation feed grinding wheel, which includes:

[0009] A carriage mechanism and a first driving mechanism, wherein the carriage mechanism includes a bottom plate and a slide plate slidably connected together, and the first driving mechanism is used to drive the slide plate to slide;

[0010] a grinding wheel and a second driving mechanism, wherein the second driving mechanism is fixed to the slide and is used to drive the grinding wheel to rotate;

[0011] Wherein, the base plate is fixedly provided with a clamp, the slide plate is fixedly provided with a first guide rail, and the clamp is used to lock or release the first guide rail.

[0012] In a preferred embodiment of the present invention, a technical solution for the specific structural arrangement of the clamp is provided.

[0013] The clamp includes a clamp body, a slide groove is provided on the clamp body, an extendable clamping structure is provided in the clamp body, the first guide rail is arranged in the slide groove, and the clamping structure is used to clamp the first guide rail when extended.

[0014] Furthermore, the clamp body is further provided with an air inlet, an air path is provided in the clamp body, and the air inlet is communicated with the clamping structure through the air path.

[0015] Furthermore, the clamping structure is a push rod, and the side wall of the first guide rail is provided with a groove adapted to the push rod.

[0016] Furthermore, one end of the base plate away from the first driving mechanism protrudes outward to form a protrusion, the clamp is fixed on the protrusion, the first guide rail is fixed to the bottom of the slide, and at least part of the structure of the first guide rail protrudes from the slide.

[0017] In another preferred embodiment of the present invention, a technical solution for the transmission mode of the drag plate mechanism is provided.

[0018] The drag plate mechanism further includes a second guide rail, which is arranged between the base plate and the slide plate, and the base plate and the slide plate are slidably connected via the second guide rail.

[0019] The second guide rail is a cross guide rail.

[0020] In another preferred embodiment of the present invention, a technical solution is provided for realizing the automatic compensation function.

[0021] The pneumatic automatic compensation feed grinding wheel also includes a control module and a detection module. The control module is electrically connected to the detection module and the clamp respectively. The detection module is used to detect the glass position, and the control module is used to control whether the clamp locks the first guide rail according to the glass position information.

[0022] In another preferred embodiment of the present invention, a technical solution regarding the structural arrangement of the first drive mechanism and the second drive mechanism is provided.

[0023] The first driving mechanism is a cylinder, the cylinder body of the cylinder is fixed on the base plate, and the piston rod of the cylinder is fixedly connected to the slide plate for driving the slide plate to slide.

[0024] Furthermore, the second driving mechanism is a servo motor, and the output shaft of the servo motor is fixedly connected to the grinding wheel for driving the grinding wheel to rotate.

[0025] In summary, the working principle of the pneumatic automatic compensation feed grinding wheel provided by the present invention is as follows:

[0026] When the grinding wheel is edging the glass, the first drive mechanism applies a flexible forward force to the slide. The clamp is now released, and the grinding wheel on the slide, under the force of the first drive mechanism, contacts the edge of the glass and completes the grinding operation. After the edging of a piece of glass is completed, the clamp switches to a locked state. This locks the first guide rail on the slide, preventing it from sliding relative to the base plate, thereby securing the grinding wheel. The next piece of glass can then be replaced. Once the next piece of glass is in place, the clamp switches back to a released state, and the first drive mechanism continues to apply a flexible forward force to the slide, causing the grinding wheel on the slide to contact the edge of the glass and complete the grinding operation for the next piece of glass. This cycle continues, allowing the edging of multiple pieces of glass to be completed continuously.

[0027] Compared with the existing technology, the above structural design has at least the following beneficial effects:

[0028] 1) After completing the edging process of a piece of glass, the clamp locks the first guide rail on the slide to fix the position of the grinding wheel, ensuring that when the next piece of glass is replaced, the grinding wheel will not be fed forward due to the force of the first drive mechanism, thereby realizing continuous processing of multiple pieces of glass with high operating efficiency.

[0029] 2) When the next piece of glass reaches the preset processing position, the clamp no longer locks the first guide rail. At this time, even if the grinding wheel is worn, the grinding wheel will be pushed forward by the first driving mechanism and will not stop feeding until it contacts the glass, thereby automatically achieving distance compensation for the wear of the grinding wheel. Compared with the design method of manually adjusting the position of the limiting structure according to the glass edge grinding effect in the prior art, the present invention can automatically and accurately achieve the distance compensation function for the wear of the grinding wheel when any glass is in place, without lag. Moreover, in this process, no matter how much the grinding wheel wears, since the grinding wheel will stop feeding until it contacts the glass under the driving force, it can ensure that the grinding wheel can contact the edge of the glass when processing any glass, thereby ensuring the processing accuracy of the glass.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0038] Example 1

[0039] See also Figure 1 and Figure 2 As shown, in the first embodiment of the present invention, the pneumatic automatic compensating feed grinding wheel includes a carriage mechanism and a first drive mechanism 3. The carriage mechanism includes a base plate 1 and a slide plate 2 arranged from bottom to top, the base plate 1 and the slide plate 2 being slidably connected together. The first drive mechanism 3 is used to drive the slide plate 1 to slide relative to the base plate 1. The carriage mechanism is preferably arranged in a horizontal direction, in which case the slide plate 1 can slide horizontally relative to the base plate 1.

[0040] See also Figure 1 As shown, the pneumatic automatic compensation feed grinding wheel also includes a grinding wheel 4 and a second drive mechanism 5. The second drive mechanism 5 is fixed to the slide 2. Therefore, when the slide 1 slides relative to the base plate 1, it can drive the second drive mechanism 5 to move synchronously, realizing the feed stroke of the grinding wheel 4. In addition, the second drive mechanism 5 is used to drive the grinding wheel 4 to rotate, so that the grinding wheel 4 completes the grinding operation on the glass edge grinding machine.

[0041] See also Figure 1 and Figure 2 As shown, in the technical solution of this embodiment, the base plate 1 is fixedly provided with a clamp 6, and the slide plate 2 is fixedly provided with a first guide rail 7. The clamp 6 has a locked and released state. When the clamp 6 is in the locked state, the clamp 6 locks the first guide rail 7, thereby restricting the slide plate 2 from sliding relative to the base plate 1, thereby fixing the position of the grinding wheel 4. When the clamp 6 is in the released state, the clamp 6 no longer locks the first guide rail 7, and the grinding wheel 4 on the slide plate 2 abuts the edge of the glass under the flexible force of the first drive mechanism 3, completing the grinding operation on the glass edge.

[0042] The working principle of the utility model to realize the automatic compensation function by locking and loosening the first guide rail 7 by the clamp 6 is as follows:

[0043] 1) When the grinding wheel 4 is grinding the glass, the first drive mechanism 3 applies a forward flexible force to the slide 2. At this time, the clamp 6 is in a loose state. The grinding wheel 4 on the slide 2 abuts against the edge of the glass under the action of the first drive mechanism 3 and completes the grinding operation.

[0044] 2) After completing the edging process of a piece of glass, the clamp 6 switches to the locking state. At this time, the clamp 6 locks the first guide rail 7 on the slide 2, so that the slide 2 cannot slide relative to the base plate 1, that is, it plays the role of fixing the grinding wheel 4. At this time, the glass edge grinding machine can be replaced with the next piece of glass.

[0045] 3) After the next piece of glass is in place, the clamp 6 switches to the loose state again. At this time, the first drive mechanism 3 continues to apply a flexible force to the slide 2 to feed forward, so that the grinding wheel 4 on the slide 2 abuts against the edge of the glass and completes the grinding operation of the next piece of glass.

[0046] 4) Repeat this cycle to continuously complete the edge grinding process for multiple pieces of glass.

[0047] During the entire processing process, the first drive mechanism 3 continuously applies a flexible force to feed forward to the slide 2, and realizes the fixing of the position of the grinding wheel 4 or the switching of the forward feeding state by switching the locking and releasing states of the clamp 6, and then automatically realizes the distance compensation of the wear of the grinding wheel 4 under the action of the clamp 6 and the force of the first drive mechanism 3.

[0048] More specifically, after completing the edge grinding process on a single piece of glass, the clamp 6 locks the first guide rail 1 on the slide 2 to secure the position of the grinding wheel 4. This ensures that when the next piece of glass is replaced, the grinding wheel 4 is not forced forward by the force of the first drive mechanism 3, thereby enabling continuous processing of multiple pieces of glass and improving operational efficiency. When the next piece of glass reaches the preset processing position, the clamp 6 releases the lock on the first guide rail 7. At this point, even if the grinding wheel 4 is worn, it will continue to advance under the action of the first drive mechanism 3 until it contacts the edge of the glass, thus automatically compensating for the wear of the grinding wheel 4.

[0049] Through the above-described structural design, the present invention automatically and accurately compensates for the wear of the grinding wheel 4 when any glass reaches a preset processing station, without hysteresis. This solves the problem of the prior art of manually adjusting the position of the limiting structure for distance compensation, which results in cumbersome operation and large errors. Furthermore, regardless of the wear of the grinding wheel 4, since the grinding wheel 4 only stops feeding when it contacts the glass under the driving force, it can ensure that the grinding wheel 4 contacts the edge of the glass during processing, thereby ensuring the processing accuracy of the glass.

[0050] Example 2

[0051] In the second embodiment of the present invention, a technical solution for the specific structural arrangement of the clamp 6 is provided on the basis of the first embodiment.

[0052] See also Figure 3As shown, in the technical solution of this embodiment, the clamp 6 includes a clamp body 61, which is provided with a slide groove. The clamp body 61 is provided with an extendable clamping structure. The first guide rail 7 is disposed within the slide groove. The clamping structure is used to clamp the first guide rail 7 when extended. Specifically, the slide groove is provided at the top of the clamp body 61, and the clamp body 61 as a whole has a "concave" shape with the opening facing upward. When the clamping structure is not extended from the clamp body 61, the clamp 6 is in a loose state, and the first guide rail 7 can slide back and forth within the slide groove. When the clamping structure is extended, the clamp 6 is in a locked state, and the clamping structure clamps the first guide rail 7 to limit the feed stroke of the slide 2.

[0053] See also Figure 3 As shown, in a preferred embodiment of this embodiment, the clamp body 61 further includes an air inlet 62. An air path is provided within the clamp body 61, and the air inlet 62 communicates with the clamping structure through the path. The air inlet 62 is connected to an external pipeline. When air is introduced into the air inlet 62 from the external pipeline, the air enters the air path within the clamp body 61, exerting force on the clamping structure, causing it to extend from the clamp body 61 and clamp the first guide rail 7, achieving a locking function. This design allows the clamp 6 to automatically pneumatically compensate for the feed stroke of the grinding wheel 4.

[0054] Furthermore, the clamping structure in this embodiment can preferably be a push rod, and the side walls of the first guide rail 7 are provided with grooves that match the push rods. Preferably, there are two push rods, one on each of the left and right side walls of the chute; the other two grooves are also provided, one on each of the left and right side walls of the first guide rail 7. When the two push rods extend from the clamp body 61, their ends match the grooves of the first guide rail 7, thereby locking the first guide rail 7.

[0055] Of course, the clamping structure in this embodiment may also adopt a clamping plate, and the locking function of the clamp 6 is achieved by clamping the first guide rail 7 through the extended clamping plate.

[0056] See also Figure 1-Figure 3 As shown, in another preferred embodiment of the present invention, one end of the base plate 1 away from the first drive mechanism 3 protrudes outward to form a protrusion 11, the clamp 6 is fixed on the protrusion 11, the first guide rail 7 is fixed to the bottom of the slide 2, and at least part of the structure of the first guide rail 7 is protruding from the slide 2. In the above structural design, the slide groove of the clamp 6 is set toward the top, and the first guide rail 7 is just located in the slide groove. The clamp 6 is used to lock or release the first guide rail 7 that is set protruding from the slide 2. Compared with setting the clamp 6 inside the drag plate mechanism (that is, between the base plate 1 and the slide 2), the structural design of this embodiment has the advantage of facilitating the installation, disassembly, maintenance and repair of the clamp 6, and does not need to occupy the internal space of the drag plate mechanism.

[0057] Example 3

[0058] In the third embodiment of the present invention, a technical solution for the transmission mode of the drag plate mechanism is provided on the basis of the first embodiment.

[0059] See also Figure 3 As shown, in the technical solution of this embodiment, the carriage mechanism includes a second guide rail 8, which is disposed between the base plate 1 and the slide plate 2. The base plate 1 and the slide plate 2 are slidably connected via the second guide rail 8. Specifically, there are at least two second guide rails 8, one of which is fixedly connected to the base plate 1 and the other is fixedly connected to the slide plate 2. The two second guide rails 8 are slidably connected to each other, thereby enabling the slide plate 3 to slide on the base plate 2. Through this design, the carriage mechanism can arrange multiple guide rails in the cavity space between the base plate 2 and the slide plate 3, effectively preventing impurities such as dust and liquid from entering the second guide rail 8, reducing the impact of the external environment on the second guide rail 8, and ensuring the smooth operation of the carriage mechanism.

[0060] Preferably, the second guide rail 8 can be a cross guide rail, and further, a cross roller guide rail can be used.

[0061] Example 4

[0062] In the fourth embodiment of the present invention, a technical solution for realizing the automatic compensation function is provided based on the first embodiment.

[0063] In the technical solution of this embodiment, the pneumatic automatic compensation feed grinding wheel further includes a control module and a detection module, and the control module is electrically connected to the detection module and the clamp 6 respectively. The above-mentioned electrical connection can be electrically connected through a wire or through a wireless transmission method such as WIFI and Bluetooth.

[0064] Specifically, the detection module detects the position of the glass and transmits this information to the control module. This information includes information indicating that the previous glass has completed processing and left the preset processing station, and that the next glass has moved to the preset processing station. Based on this information, the control module determines and controls whether the clamp 6 locks or releases the first guide rail 7. If the detection module detects that the glass has completed processing and left the station, the control module controls the clamp 6 to lock the first guide rail 7. If the detection module detects that the next glass has moved to the preset processing station, the control module controls the clamp 6 to release the first guide rail 7.

[0065] Preferably, the detection module in this embodiment may be a light source detection module, such as a photoelectric sensor, etc., which detects the position of the glass through a light source; and the control module may be a central controller.

[0066] Example 5

[0067] In the fifth embodiment of the present invention, a technical solution for the structural arrangement of the first driving mechanism 3 and the second driving mechanism 5 is provided on the basis of the first embodiment.

[0068] See also Figure 1 As shown, in one technical solution of this embodiment, the first drive mechanism 3 is a cylinder, the cylinder body of which is fixed to the base plate 1, and the cylinder piston rod is fixedly connected to the slide plate 2. The cylinder drives the slide plate 2 to slide through the linear motion of the piston rod. The cylinder body can be fixed to the side of the base plate 1 away from the grinding wheel 4 via a mounting plate, and the piston rod is fixedly connected to the bottom of the slide plate 2 via fastening members such as bolts and screws. The piston rod is hidden between the base plate 1 and the slide plate 2, thereby achieving the forward feed motion of the grinding wheel 4.

[0069] See also Figure 1 As shown, in another technical solution of this embodiment, the second drive mechanism 5 is a servo motor, the output shaft of which is fixedly connected to the grinding wheel 4, for driving the grinding wheel 4 to rotate. The output shaft of the servo motor can be directly connected to the grinding wheel 4, driving the grinding wheel 4 to rotate via the output shaft to complete the grinding operation on the glass edge. Furthermore, a reduction mechanism can be provided between the output shaft of the servo motor and the grinding wheel 4. The output shaft of the servo motor is connected to the input end of the reduction mechanism, and the grinding wheel 4 is connected to the output end of the reduction mechanism. This transmission action of the reduction mechanism transmits torque between the servo motor and the grinding wheel 4, facilitating matching of the rotational speed of the grinding wheel 4.

[0070] In summary, after the pneumatic automatic compensation feed grinding wheel provided by the present invention completes the edging process of a piece of glass, the clamp 6 locks the first guide rail 7 on the slide 2 to fix the position of the grinding wheel 4, ensuring that when the next piece of glass is replaced, the grinding wheel 4 will not be fed forward due to the force of the first drive mechanism 3, thereby achieving continuous processing of multiple pieces of glass with high operating efficiency. In addition, compared with the design method of manually adjusting the position of the limit structure according to the glass edging effect in the prior art, the present invention can automatically and accurately realize the distance compensation function of the grinding wheel wear when any glass is in place, without hysteresis. In this process, no matter how much the grinding wheel 4 wears, since the grinding wheel 4 will stop feeding when it contacts the glass under the driving force, it can ensure that the grinding wheel 4 can contact its edge when processing any glass, thereby ensuring the processing accuracy of the glass.

[0071] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
