Description
Technical Field
The present utility model relates to a technique of a sheet glass processing apparatus.
Background
For example, in a process for producing a sheet glass used as a substrate or cover glass for a liquid crystal display or the like, one or more sheets of sheet glass are cut from a large-sized glass raw sheet, thereby forming a sheet glass having a desired outer dimension.
Here, there is a case where there is little damage to the end face of the sheet glass immediately after cutting from the glass raw sheet.

Problems to be solved by the utility model
In the above-described conventional processing apparatus, the processing tool is located upstream of the support shaft member in the moving direction of the moving mechanism (more specifically, in the feeding direction of the processing tool when performing end surface processing of the sheet glass).
The machining tool and the driving device for rotationally driving the machining tool are provided at one end portion of the support member, and the support member is bordered by the support shaft member, and the one end portion of the support member is heavier than the other end portion of the support member.
Therefore, when the moving mechanism is moved in an accelerated manner to bring the processing tool closer to the plate glass placed on the upper surface of the suction table, the support member tends to rotate about the support shaft member toward the side separated from the plate glass due to the influence of inertia at the heavy end (i.e., the end on the processing tool side).
As a result, immediately after the movement of the movement mechanism is switched from the acceleration movement to the constant-speed movement, the processing tool does not sufficiently come into contact with the end surface of the sheet glass, and an unprocessed region is generated in the end surface of the sheet glass on the upstream side in the movement direction (feed direction).

Detailed Description
Next, an embodiment of the present utility model will be described with reference to fig. 1 to 3.
In the following description, for convenience, the front-rear direction and the left-right direction of the sheet glass processing apparatus 1 are defined and described by the directions of arrows shown in fig. 1 to 3.
[ Whole structure of sheet glass processing apparatus 1 ]
First, the overall structure of a sheet glass processing apparatus 1 embodying the present utility model will be described with reference to fig. 1.
The sheet glass processing apparatus 1 of the present embodiment is an apparatus for performing end face processing such as grinding (rough processing) and polishing (finish processing) on the end face Ga of the sheet glass G cut from a large-sized glass raw sheet.
The sheet glass processing apparatus 1 is disposed adjacent to the suction table M on which the sheet glass G is placed.
The sheet glass processing apparatus 1 mainly includes: a cylindrical machining tool 2; a driving device 3 for rotationally driving the machining tool 2; an arm member 4 for supporting the machining tool 2 together with the driving device 3; a servo mechanism 5 for applying a force (pressing force) to press the end face Ga of the plate glass G to the processing tool 2 via the arm member 4; a moving mechanism 6 for moving the processing tool 2, the driving device 3, the arm member 4, and the servo mechanism 5 along the end face Ga of the sheet glass G; and a control device 7 for controlling the operation of the entire glass processing apparatus 1.
The sheet glass processing apparatus 1 further includes a stopper.
The stopper includes a downstream stopper 8, and the downstream stopper 8 is located on the front side of the arm member 4 (more specifically, on the moving direction of the processing tool 2 when the end surface processing of the sheet glass G is performed), and is movable in the approaching-separating direction with respect to the arm member 4.
The downstream stopper 8 is an example of the first stopper of the present utility model.
The machining tool 2 is made of, for example, a commercially available grindstone (grinding grindstone or polishing grindstone), and is disposed so as to have an axial direction oriented vertically.
The driving device 3 is configured by an electric motor, such as a synchronous motor, an asynchronous motor, or a servo motor, for example, and is configured such that the output shaft 3a is disposed to face upward in a state in which the output shaft 3a is coaxially inserted into the machining tool 2.
The arm member 4 is constituted by an elongated plate member extending in one direction, and is disposed with the planar portion facing both the upper and lower sides.
The arm member 4 is supported at a substantially central portion in the extending direction by a support shaft member 41 having an axial direction in the up-down direction so as to be rotatable (swingable) about the support shaft member 41.
The machining tool 2 is disposed on the upper surface of the arm member 4 together with the driving device 3 at one end in the extending direction. Therefore, the processing tool 2 is rotatably supported by the arm member 4.
The other end portion of the arm member 4 in the extending direction is connected to a link mechanism 51 of a servo mechanism 5 described later.
The arm member 4 is rotated about the support shaft member 41 toward one side (the direction of arrow X1 in fig. 1) by the servo mechanism 5, and moves the processing tool 2 in a direction approaching the sheet glass G (hereinafter, appropriately referred to as "cutting direction a").
The arm member 4 is rotated about the support shaft member 41 toward the other side (the direction of arrow X2 in fig. 1) by the servo mechanism 5, and moves the processing tool 2 in a direction separating from the sheet glass G (hereinafter, appropriately referred to as "retracting direction B").
The cutting direction a and the retracting direction B are directions perpendicular to a moving direction of the moving mechanism (more specifically, a feeding direction C described later) in a plan view.
In this way, the arm member 4 can adjust the position of the processing tool 2 in the cutting direction a by the rotation operation of the support shaft member 41.
Thereby, the force (pressing force) with which the processing tool 2 presses the end face Ga of the plate glass G can be adjusted.
The servo mechanism 5 includes a link mechanism 51 connected to the arm member 4, and a servo motor 52 driving the link mechanism 51.
The link mechanism 51 has a first link member 51a and a second link member 51b.
The first link member 51a is inserted at one end portion into the output shaft 52a of the servomotor 52, and is rotatably coupled at the other end portion to one end portion of the second link member 51b via the first joint 53.
The second link member 51b is rotatably coupled to the other end portion of the arm member 4 via a second joint 54.
The link mechanism 51 applies a rotational force of the output shaft 52a of the servomotor 52 to the arm member 4 as a moment, and the pressing force of the end face Ga of the sheet glass G is generated by the processing tool 2 due to the moment.
In other words, the servo 5 displaces the arm member 4 in a direction in which the processing tool 2 presses the end face Ga of the sheet glass G (i.e., the cutting direction a).
The servomotor 52 is an example of the output adjustment mechanism of the present utility model, and is configured as an adjustment mechanism that adjusts the position of the working tool 2 to a predetermined position (working tool holding position P1 described later) with respect to the end face Ga of the plate glass G as described later.
The servomotor 52 drives the link mechanism 51 so as to maintain the pressing force of the processing tool 2 against the end face Ga of the plate glass G constant.
As will be described later, the servo motor 52 can adjust the position of the arm member 4 via the link mechanism 51 so that the position of the processing tool 2 becomes a predetermined position with respect to the end face Ga of the sheet glass G.
That is, the servo motor 52 is feedback-controlled by the control device 7 described later, and adjusts the driving force of the link mechanism 51 to the arm member 4 based on the torque.
The information about the torque of the servomotor 52 and the rotation angle of the output shaft 52a is transmitted to the control device 7 by the communication device.
The moving mechanism 6 includes a guide rail 61 disposed along an end face Ga of the plate glass G placed on the upper surface of the suction stage M, a driving portion 62 guided along the upper surface of the guide rail 61, and a base 63 provided on an upper portion of the driving portion 62, and a support shaft member 41 for rotatably (swingably) supporting the arm member 4 and a servomotor 52 for driving the link mechanism 51 are disposed on an upper surface 63a of the base 63.
The driving unit 62 is configured by, for example, a ball screw mechanism driven by a servo motor, a linear actuator such as a linear servo motor, or the like, and can adjust the cutting position of the processing tool 2 supported by the arm member 4 by moving the base 63 in the cutting direction a and the retracting direction B.
The moving mechanism 6 moves the arm member 4 in one direction (in the present embodiment, the front direction, hereinafter, appropriately referred to as "feed direction C") along the end face Ga of the plate glass G on the suction stage M, and thereby causes the processing tool 2 to press the end face Ga to perform end face processing on the end face Ga of the plate glass G.
The control device 7 includes an arithmetic processing unit constituted by CPU (Central Processing Unit), a storage unit constituted by ROM (Read Only Memory), RAM (Random Access Memory), HDD (Hard Disk Drive), and the like.
The storage unit stores a program for adjusting the output of the servo mechanism 5, that is, the torque generated by the servo motor 52 by feedback control in a case where the processing tool 2 is held at a predetermined position during acceleration movement of the moving mechanism 6, or in a case where the force (pressing force) with which the processing tool 2 presses the end face Ga of the sheet glass G during constant-speed movement of the moving mechanism 6, as will be described later.
The storage unit stores programs for controlling the operations of the driving device 3, the driving unit 62 of the moving mechanism 6, and the like.
The control device 7 controls the operation of the entire glass processing apparatus 1 according to an operation flow described later, and performs end face processing on the end face of the plate glass G placed on the upper surface of the suction table M.
[ flow of operation of sheet glass processing apparatus 1 ]
Next, an operation flow in the case of performing end face processing (rough processing or finish processing) on the end face Ga of the sheet glass G in the sheet glass processing apparatus 1 of the present embodiment will be described with reference to fig. 2.
First, the driving device 3 stops the rotation driving of the processing tool 2.
The servo mechanism 5 is configured to hold the processing tool 2 at a predetermined retracted position (not shown) located on the retraction direction B side via the arm member 4.
The moving mechanism 6 is configured to hold the base 63 at a predetermined standby position (not shown) located upstream in the feeding direction C.
In this state, when the end face machining operation by the sheet glass machining device 1 is started, the driving device 3 starts the rotational driving of the machining tool 2.
After the downstream stopper 8 moves to a predetermined position in the approaching direction to the arm member 4, the servo 5 rotates the arm member 4 to one side (the direction of arrow X1 in fig. 1) around the support shaft member 41, and brings the arm member 4 into contact with the downstream stopper 8.
As a result, the position of the tool 2 is moved to the cutting direction a side with respect to the end face Ga of the plate glass G placed on the upper surface of the suction table M, and is held at a predetermined position (hereinafter, appropriately referred to as "tool holding position P1").
When the machining tool 2 is held at the machining tool holding position P1, the moving mechanism 6 starts the acceleration movement of the base 63 from the standby position toward the feeding direction C.
When the base 63 reaches the processing start position L1 where the processing tool 2 is in contact with the end face Ga of the sheet glass G, the movement mechanism 6 switches the movement operation of the base 63 from the acceleration movement to the constant-speed movement.
The downstream stopper 8 is moved to a predetermined position in a separating direction from the arm member 4, and the processing tool 2 is brought into a state in which a predetermined pressing force is applied by the servo 5 in a direction toward the end face Ga of the pressing plate glass G.
Here, the torque of the servomotor 52 when the processing tool 2 is held at the processing tool holding position P1 is set to be larger than the torque of the servomotor 52 when the processing tool 2 is pressed against the end face Ga of the plate glass G.
In other words, the control device 7 adjusts the output of the servo mechanism 5 so that the output is greater when the movement of the base 63 (more specifically, the arm member 4 supporting the processing tool 2) by the movement mechanism 6 is the acceleration movement than when the movement is the constant-speed movement.
With this configuration, in the moving mechanism 6, the base 63 is moved with acceleration to bring the processing tool 2 close to the sheet glass G, and then, at the timing when the processing start position L1 where the processing tool 2 is brought into contact with the end face Ga of the sheet glass G is reached, the movement of the base 63 is switched from the acceleration movement to the constant-speed movement, so that even when the end face processing is performed by pressing the processing tool 2 against the end face Ga of the sheet glass G, the influence of inertia caused by the acceleration movement of the base 63 can be suppressed by the control device 7, and the position of the processing tool 2 can be held at the processing tool holding position P1 more reliably.
The machining tool 2 moves along the end face Ga of the sheet glass G in the feeding direction C by the constant-speed movement of the base 63 by the movement mechanism 6, and performs end face machining (rough machining or finish machining) on the end face Ga.
After that, when the end surface machining is completed and the base 63 reaches the machining completion position L2 where the machining tool 2 passes through the end surface Ga of the sheet glass G, the moving mechanism 6 switches the movement operation of the base 63 from the constant speed movement to the deceleration movement, and stops the operation of the base 63.
The driving device 3 stops the rotational driving of the machining tool 2.
The servo 5 rotates the arm member 4 about the support shaft member 41 toward the other side (the direction side of arrow X2 in fig. 1) to move the processing tool 2 to the retracted position.
When the plate glass G having finished the end surface processing is taken out from the suction table M, the moving mechanism 6 moves the base 63 to the opposite side to the feeding direction C, and stops the movement of the base 63 when the base 63 reaches the standby position.
Thus, a series of operation flows in the sheet glass processing apparatus 1 are completed.
As described above, the sheet glass processing apparatus 1 of the present embodiment is configured to include: a processing tool 2 capable of abutting against the end face Ga of the plate glass G; an arm member 4 for rotatably supporting the processing tool 2; a servo mechanism 5 for displacing the arm member 4 in a direction (cutting direction a) in which the processing tool 2 presses the end face Ga of the sheet glass G; a moving mechanism 6 that moves the arm member 4 along an end face Ga (toward the feeding direction C) of the plate glass G; and an adjustment mechanism (for example, a servomotor 52 provided to the servo mechanism 5 in the present embodiment) that adjusts the position of the processing tool 2 to a predetermined position (processing tool holding position P1) with respect to the end face Ga of the plate glass G.
According to the sheet glass processing apparatus 1 of the present embodiment, for example, when the moving mechanism 6 accelerates the movement of the base 63 to move the processing tool 2 toward the sheet glass G placed on the upper surface of the suction table M, the processing tool 2 can be reliably held at a predetermined position (processing tool holding position P1) by the above-described adjusting mechanism (servo motor 52) even if the processing tool 2 is to be moved to a side (retreat direction B side) separated from the sheet glass G under the influence of inertia.
Therefore, unlike the conventional processing apparatus, the processing tool 2 does not sufficiently abut against the end face Ga of the sheet glass G immediately after the movement of the moving mechanism 6 (more specifically, the base 63) is switched from the acceleration movement to the constant-speed movement, and an unprocessed region is not generated in the upstream side portion in the movement direction (the feeding direction C of the processing tool) of the base 63 of the moving mechanism 6 in the end face Ga of the sheet glass G, so that the end face Ga of the sheet glass G can be processed with higher quality.
In the sheet glass processing apparatus 1 of the present embodiment, the adjustment mechanism is constituted by a servo motor (output adjustment mechanism) 52 for adjusting the output of the servo mechanism 5.
With this configuration, the servo motor 52 for adjusting the output of the servo mechanism 5 can be used to construct the adjustment mechanism without providing a separate new mechanism for adjusting the position of the machining tool 2 to a predetermined position (machining tool holding position P1), and therefore, the equipment cost can be reduced.
In the sheet glass processing apparatus 1 of the present embodiment, the moving mechanism 6 is configured to be capable of switching the movement operation of the arm member 4 by the base 63 to the acceleration movement and the constant-speed movement, and the servo motor (output adjustment mechanism) 52 is configured to be controlled by the control device 7 to adjust the output of the servo mechanism 5 in accordance with the movement operation of the arm member 4 by the base 63 of the moving mechanism 6.
With this configuration, according to the sheet glass processing apparatus 1 of the present embodiment, the position of the processing tool 2 can be more appropriately held at the predetermined position (processing tool holding position P1) by the servo motor (output adjustment mechanism) 52 in accordance with the movement operation of the arm member 4 by the base 63 of the movement mechanism 6.
[ Integrated structure of sheet glass processing apparatus 101 (another embodiment) ]
Next, the overall structure of a sheet glass processing apparatus 101 according to another embodiment will be described with reference to fig. 3.
The sheet glass processing apparatus 101 of the other embodiment has a structure substantially equivalent to that of the sheet glass processing apparatus 1 of the present embodiment described above, but is different from the sheet glass processing apparatus 1 in terms of a structure of an adjusting mechanism for adjusting a position of the processing tool 102 to a predetermined position (processing tool holding position P1) with respect to the end face Ga of the sheet glass G.
Therefore, in the following description, mainly the differences from the sheet glass processing apparatus 1 of the present embodiment will be described, and the description of the structures equivalent to those of the sheet glass processing apparatus 1 will be omitted.
The sheet glass processing apparatus 101 according to the present embodiment mainly includes a processing tool 102, a driving device 103, an arm member 104, a servo 105, a moving mechanism 106, and a control device 107.
The machining tool 102, the driving device 103, the arm member 104, the servo mechanism 105, the moving mechanism 106, and the control device 107 are configured to be substantially identical to the machining tool 2, the driving device 3, the arm member 4, the servo mechanism 5, the moving mechanism 6, and the control device 7 of the present embodiment described above, and therefore description thereof will be omitted.
The sheet glass processing apparatus 101 further includes a downstream stopper 108 located on the side of the arm member 104 in the moving direction (more specifically, the feeding direction C) of the arm member 104 by the moving mechanism 106, and an upstream stopper 109 located on the opposite side of the arm member 104 from the moving direction.
The downstream stopper 108 is an example of the first stopper of the present utility model, and the upstream stopper 109 is an example of the second stopper of the present utility model.
The downstream stopper 108 is configured to be movable in the approaching/separating direction with respect to the arm member 104 by, for example, an air pressure type first actuator 108 a.
The upstream stopper 109 is also configured to be movable in the approaching/separating direction with respect to the arm member 104 by an air pressure type second actuator 109a, for example, similarly to the downstream stopper 108.
The second actuator 109a is an example of the stopper position adjustment mechanism of the present utility model, and is configured to be able to adjust the position of the upstream stopper 109 by arbitrarily changing the stroke of the telescopic rod.
In addition, the pressing force of the arm member 104 by the second actuator 109a via the upstream side stopper 109 is set to be larger than the pressing force of the arm member 104 by the first actuator 108a via the downstream side stopper 108.
Then, the distance relationship between the arm member 104 and the upstream stopper 109 is adjusted by the second actuator 109a, and the arm member 104 is sandwiched between the upstream stopper 109 and the downstream stopper 108, so that the machining tool 102 is held at a predetermined position (machining tool holding position P1).
In other words, the second actuator 109a constitutes an adjustment mechanism that adjusts the position of the processing tool 2 to a predetermined position (processing tool holding position P1) with respect to the end face Ga of the plate glass G.
As described above, the sheet glass processing apparatus 101 according to the present embodiment includes the downstream stopper (first stopper) 108 located on the side of the movement direction (feed direction C) of the arm member 104 by the movement mechanism 106 and the upstream stopper (second stopper) 109 located on the opposite side of the movement direction (feed direction C), and the adjustment mechanism is configured by the second actuator (stopper position adjustment mechanism) 109a that adjusts the position of the upstream stopper 109.
By sandwiching the arm member 104 between the downstream stopper 108 and the upstream stopper 109, for example, the movement of the processing tool 102 to the side (the retreat direction B side) separated from the sheet glass G due to the inertia of the base 163 of the moving mechanism 106 during the acceleration movement is prevented, and the position of the processing tool 102 can be more reliably held at a predetermined position (the processing tool holding position P1).
In the sheet glass processing apparatus 101 according to the present embodiment, the second actuator (stopper position adjustment mechanism) 109a is configured to be able to adjust the distance relationship between the arm member 104 and the upstream stopper (second stopper) 109.
By appropriately adjusting the distance relationship between the arm member 104 and the upstream side stopper 109, the position of the processing tool 102 can be more appropriately held at a predetermined position (processing tool holding position P1).
[ flow of operation of sheet glass processing apparatus 101 ]
Next, an operation flow in the case of performing end face processing (rough processing or finish processing) on the end face Ga of the sheet glass G in the sheet glass processing apparatus 101 according to another embodiment will be described with reference to fig. 3.
The operation flow of the sheet glass processing apparatus 101 according to the other embodiment has a configuration substantially equivalent to that of the sheet glass processing apparatus 1 according to the present embodiment described above, and is different from that of the sheet glass processing apparatus 1 in the operation flow from the start of the end surface processing to the arrival of the base 163 of the moving mechanism 106 at the processing start position L1 (see fig. 2).
Therefore, in the following description, mainly the differences from the operation flow of the sheet glass processing apparatus 1 of the present embodiment will be described, and description of the flow equivalent to the operation flow of the sheet glass processing apparatus 1 will be omitted.
When the end face machining operation by the sheet glass machining device 101 is started, the driving device 103 starts the rotational driving of the machining tool 102.
The servomotor 152 of the servo mechanism 105 is in a free state in which the output shaft 152a can be arbitrarily rotated by an external force.
Then, the first actuator 108a is operated to move the downstream stopper 108 to a predetermined position in the approaching direction to the arm member 104, and the second actuator 109a is operated to move the upstream stopper 109 to a predetermined position adjusted in advance in the approaching direction to the arm member 104.
Thus, the arm member 104 is sandwiched between the downstream stopper 108 and the upstream stopper 109, and the position of the processing tool 102 is maintained at a predetermined position (processing tool holding position P1) set in advance with respect to the end face Ga of the plate glass G placed on the upper surface of the suction table M.
When the machining tool 102 is held at the machining tool holding position P1, the movement mechanism 106 starts the acceleration movement of the base 163 in the feeding direction C from a predetermined standby position (not shown) located on the upstream side in the feeding direction C.
When the base 163 reaches the processing start position L1 where the processing tool 102 comes into contact with the end face Ga of the sheet glass G, the movement mechanism 106 switches the movement operation of the base 163 from the acceleration movement to the constant-speed movement.
The downstream stopper 108 and the upstream stopper 109 are moved to predetermined positions in the separation direction from the arm member 104, respectively, and the processing tool 102 is released from the clamped state by the downstream stopper 108 and the upstream stopper 109.
The servo motor 152 generates a predetermined torque via the output shaft 152a, and the processing tool 102 is in a state in which a predetermined pressing force is applied by the servo mechanism 105 in the direction of the end face Ga of the pressing plate glass G.
Thereafter, the processing tool 102 moves along the end face Ga of the sheet glass G in the feeding direction C by the constant-speed movement of the base 163 by the movement mechanism 106, and performs end face processing (rough processing or finish processing) on the end face Ga.
The operation flow thereafter is the same as the operation flow of the sheet glass processing apparatus 1 of the present embodiment described above, and therefore description thereof will be omitted.
As described above, in the sheet glass processing apparatus 101 according to the present embodiment, the moving mechanism 106 is configured to be capable of switching the movement operation of the arm member 104 by the base 163 to the acceleration movement and the constant speed movement, and the second actuator (stopper position adjusting mechanism) 109a is configured to adjust the distance between the arm member 104 and the upstream stopper (second stopper) 109 in accordance with the movement operation of the arm member 104 by the base 163 of the moving mechanism 106.
With this configuration, the position of the processing tool 102 can be more appropriately held at a predetermined position (processing tool holding position P1) by the second actuator (stopper position adjustment mechanism) 109a in accordance with the movement operation of the arm member 104 by the base 163 of the movement mechanism 106.
The second actuator (stopper position adjustment mechanism) 109a is configured to adjust the distance between the arm member 104 and the upstream stopper (second stopper) 109 such that the distance is closer to the arm member 104 when the movement of the arm member 104 by the base 163 of the movement mechanism 106 is the acceleration movement than when the movement is the constant-speed movement (that is, such that the upstream stopper 109 is moved in the direction approaching the arm member 104).
After the base 163 is moved by acceleration to bring the processing tool 102 close to the sheet glass G, the movement of the base 63 is switched from the acceleration to the constant-speed movement at the time of reaching the processing start position L1 where the processing tool 102 is brought into contact with the end face Ga of the sheet glass G, so that even when the end face is processed by pressing the end face Ga of the sheet glass G by the processing tool 102, the position of the processing tool 102 can be held at the processing tool holding position P1 more reliably by suppressing the influence of inertia caused by the acceleration movement of the base 163 by the second actuator (stopper adjusting mechanism) 109 a.
While the present utility model has been described with reference to the above embodiments, it is to be understood that the present utility model is not limited to the embodiments, but is merely illustrative, and that the present utility model can be embodied in various forms without departing from the spirit of the present utility model.
