Description

Technical Field

[0001] The invention relates to the field of glass safety corner processing devices, and in particular to a servo tracking glass safety corner processing device for a double-sided edge grinding machine. Background Art

[0002] At present, double-sided edge grinding machines are used to grind the edges of glass plates to avoid scratching the human body and to make the edges of glass plates smooth. Some double-sided edge grinding machines are equipped with glass safety angle processing devices. Glass safety angle refers to the chamfers formed at the four corners of the glass plate to avoid scratching the human body and to facilitate safety. The glass safety angle processing device is equipped with a grinding wheel in a circular grinding mode. The conveyor belt device of the double-sided edge grinding machine drives the glass plate to move forward, and the glass safety angle processing device moves the grinding wheel to the corner of the glass plate through the cylinder. The grinding wheel grinds the chamfer at the corner of the glass plate, and then the glass safety angle processing device resets the grinding wheel. However, in the above When the cylinder drives the grinding wheel to move toward the glass plate, since the speed of the grinding wheel driven by the above-mentioned cylinder is difficult to accurately control, it is easy to cause the relative movement speed of the grinding wheel and the glass plate to be relatively large. When the grinding wheel approaches the corner of the glass plate, it will cause a large impact on the corner of the glass, which may easily cause the glass plate to break; if the air pressure input into the above-mentioned cylinder is reduced, the speed of the grinding wheel approaching the glass plate will be too slow, and since the glass plate is continuously moved forward, it is difficult for the grinding wheel to catch up with the glass plate when processing the rear corner of the glass plate, and it will increase the working hours and lead to low production efficiency.

DETAILED DESCRIPTION

[0036] The present invention will be further described below in conjunction with the accompanying drawings.

[0037] The servo tracking glass safety angle processing device for a double-sided edge grinding machine of the present invention is as follows: Figures 1 to 8 As shown, it includes a longitudinal movement component 1, a transverse movement component 2 and a spindle component 3. The longitudinal movement component 1 is provided with a longitudinal movement servo motor component 11, a longitudinal movement table 12, a synchronous belt 14 and a feed cylinder 15. Specifically, the longitudinal movement servo motor component 11 may include a servo motor and a reducer. The longitudinal movement component 1 is also provided with a base 13, and the base 13 is used to be fixedly installed on the frame of the double-sided edge grinding machine. The longitudinal movement table 12 is slidably connected to the base 13 through two sets of corresponding linear guide rails, so that the longitudinal movement table 12 can move linearly in the front and rear directions; as shown Figure 7As shown, the longitudinal movement servo motor assembly 11 drives the connected synchronous belt 14, and a movable seat 152 is provided on the synchronous belt 14. The feed cylinder 15 is installed and connected to the longitudinal movement table 12. Specifically, the cylinder body of the feed cylinder 15 and the longitudinal movement table 12 are relatively fixed. The feed cylinder 15 is provided with a feed cylinder piston rod 1501, and the feed cylinder piston rod 1501 is installed and connected to the movable seat 152. For example, the end of the feed cylinder piston rod 1501 is threadedly connected to the movable seat 152, and the end of the feed cylinder piston rod 1501 is also threadedly connected with a nut, and the nut is tightened and pressed against the side of the movable seat 152, so that the feed cylinder piston rod 1501 and the movable seat 152 are relatively fixed. Since the movable seat 152 is set on the synchronous belt 14, and the movable seat 152 and the feed cylinder piston rod 1501 are relatively fixed, the longitudinal movement servo motor assembly 11 can drive the synchronous belt 14 to operate and drive the longitudinal movement table 12 to move in the front and rear directions. As shown in FIG. Figure 8 As shown, the transverse movement assembly 2 is provided with a transverse movement servo motor assembly 21 and a transverse movement seat 22. The transverse movement seat 22 is slidably connected to the longitudinal movement platform 12 through a corresponding linear guide pair, so that the transverse movement seat 22 can move linearly in the left and right direction relative to the longitudinal movement platform 12, and the longitudinal movement platform 12 can drive the transverse movement seat 22 to move in the front and rear direction when moving forward and backward. The transverse movement servo motor assembly 21 is installed on the mounting plate 25 through corresponding screws, as shown in FIG. Figure 4 As shown, the mounting plate 25 is mounted on the end of the longitudinal moving platform 12 by corresponding screws, and the transverse moving servo motor assembly 21 drives the transverse moving seat 22 to move in the left and right directions. For example, Figure 4As shown, the transverse movement component 2 is provided with a ball screw pair 211, the screw of the ball screw pair 211 is rotatably mounted on the longitudinal movement table 12 through corresponding bearings, the nut of the ball screw pair 211 is mounted on the bottom of the transverse movement seat 22, and the transverse movement servo motor component 21 is connected to the screw of the ball screw pair 211 through a corresponding coupling. Therefore, when the transverse movement servo motor component 21 drives the screw of the ball screw pair 211 to rotate, the transverse movement seat 22 can move in the left and right directions. The spindle assembly 3 is installed on the transverse shift seat 22, specifically, the spindle assembly 3 includes a spindle housing 32, the spindle housing 32 is adapted to pass through the transverse shift seat 22, the spindle housing 32 is relatively fixed to the transverse shift seat 22 by corresponding screws, the spindle assembly 3 is provided with a grinding wheel 33 for chamfering the glass plate 99, the transverse shift assembly 2 is provided with a grinding wheel motor 23, the grinding wheel motor 23 is installed on the transverse shift seat 22, the grinding wheel motor 23 drives the connected grinding wheel 33, specifically, the spindle assembly 3 is provided with a spindle 31, the grinding wheel motor 23 is connected to the upper end of the spindle 31 through a multi-V belt 24, and the lower end of the spindle 31 is coaxially and relatively fixedly installed with the grinding wheel 33. The glass safety angle processing device of the present invention also includes a control system, which controls the connection of the longitudinal servo motor assembly 11, the transverse servo motor assembly 21 and the feed cylinder 15. Specifically, the control system controls the connection of the feed cylinder 15 through an electric proportional valve. The electric proportional valve is a prior art. The electric proportional valve can adjust the cross-sectional area of ​​the valve core of the electric proportional valve according to the size of the control signal, thereby achieving the purpose of adjusting the pressure. The glass safety angle processing device of the present invention also includes a sensor 6 for detecting the glass plate 99. The control system is electrically connected to the sensor 6. The sensor 6 is fixedly arranged. The sensor 6 can be a non-contact sensor of the prior art. For example, the sensor 6 can be a capacitive proximity switch, which can detect glass; the sensor 6 is preferably a diffuse reflection photoelectric sensor, and the sensor 6 can be set to detect the left side or right side of the glass plate 99.

[0038] The following briefly describes the working process of the glass safety corner processing device of the present invention: the distance from the sensor 6 to the initial position of the grinding wheel 33 along the front-to-back direction is measured in advance and recorded accordingly in the control system, such as Fig.12As shown, the servo motor of the conveyor belt device of the double edging machine drives the glass plate 99 to move forward, wherein the conveyor belt of the conveyor belt device is a synchronous conveyor belt, and the pressure wheel of the pressure wheel device of the double edging machine presses the glass plate 99 on the above-mentioned synchronous conveyor belt. The synchronous conveyor belt can be provided with a meter wheel encoder of the prior art, and the control system is electrically connected to the above-mentioned meter wheel encoder. When the glass plate 99 moves forward to a certain position, the sensor 6 is triggered, and the sensor 6 transmits a connection signal to the control system. The control system calculates the real-time position information of the glass plate 99 through the above-mentioned meter wheel encoder, and the control system controls the transverse servo motor assembly 21 to drive the grinding wheel 33 to move out to the right accordingly, and the control system then controls the longitudinal servo motor assembly 11 to drive the grinding wheel 33 to move forward, and the forward movement speed of the grinding wheel 33 is less than the forward movement speed of the glass plate 99, as shown in FIG. Fig.13 As shown, the grinding wheel 33 is relatively close to the front corner of the glass plate 99. When the outer circumference of the grinding wheel 33 corresponding to the front corner of the glass plate 99 is about 5 mm to 10 mm away from the front corner of the glass plate 99 in the front-to-back direction, the control system controls the longitudinal servo motor assembly 11 to make the grinding wheel 33 and the glass plate 99 move forward synchronously. The control system then controls the feed cylinder 15 to extend the feed cylinder piston rod 1501, so that the cylinder body of the feed cylinder 15 moves backward relative to the movable seat 152. Since the cylinder body of the feed cylinder 15 is relatively fixed to the longitudinal platen 12, the grinding wheel 33 further approaches and contacts the front corner of the glass plate 99, as shown in FIG. Figure 14 to Figure 15 As shown, the grinding wheel 33 processes a chamfer 991 at the front corner of the glass plate 99. When the front corner of the glass plate 99 is processed, the control system causes the grinding wheel 33 to move forward quickly to separate from the glass plate 99, and then the control system causes the grinding wheel 33 to move leftward to reset, and the control system then controls the longitudinal movement servo motor assembly 11 to cause the longitudinal movement platen 12 to move backward to reset; Fig.16 As shown, the glass plate 99 keeps moving forward. When the sensor 6 leaves the rear end of the glass plate 99, the disconnection signal of the sensor 6 is transmitted to the control system. The control system correspondingly delays the control of the transverse servo motor assembly 21 to push the grinding wheel 33 to the right, and the control system controls the longitudinal servo motor assembly 11 to drive the grinding wheel 33 to move forward, so that the grinding wheel 33 can quickly track the glass plate 99 forward. Fig.17 As shown, when the outer circumference of the grinding wheel 33 corresponding to the rear corner of the glass plate 99 is about 5 mm to 10 mm away from the rear corner of the glass plate 99 in the front-to-back direction, the control system controls the longitudinal servo motor assembly 11 to make the grinding wheel 33 and the glass plate 99 move forward synchronously, and the control system then controls the feed cylinder 15 to retract the feed cylinder piston rod 1501, so that the cylinder body of the feed cylinder 15 moves forward relative to the movable seat 152, so that the grinding wheel 33 further approaches and contacts the rear corner of the glass plate 99, as shown in FIG. Fig.18As shown, the rear corner of the glass plate 99 is also processed to form a chamfer 991. The control system controls the longitudinal servo motor assembly 11 to drive the grinding wheel 33 to move backward away from the glass plate 99, and then the transverse servo motor assembly 21 drives the grinding wheel 33 to reset. Compared with the prior art, since the glass safety angle processing device of the present invention uses the longitudinal servo motor assembly 11 to drive the grinding wheel 33 to move and track the glass plate 99, it has a fast starting speed and can make the grinding wheel 33 approach the glass plate 99 at high speed and high precision. Since the grinding wheel 33 first moves synchronously with the glass plate 99 and then drives the grinding wheel 33 to feed and grind the corner of the glass plate 99 through the feed cylinder 15, it is beneficial to stabilize the grinding process and improve the processing quality. The corner of the glass plate 99 is not easy to break due to impact. By setting the transverse servo motor assembly 21 to drive the grinding wheel 33 to move, The position of the grinding wheel 33 in the left-right direction when grinding the glass plate 99 is controllable and accurate, which is beneficial to accurately control the size of the chamfer 991, and the grinding wheel 33 moves left and right at a fast speed; since the control system controls the feed cylinder 15 through an electrical proportional valve, when the thickness of the glass plate 99 is large, the air pressure of the input feed cylinder 15 can be adjusted more accurately through electrical control, which is beneficial for the grinding wheel 33 to efficiently grind the corner position of the glass plate 99; from the above, it can be seen that the glass safety angle processing device of the present invention has excellent working performance and is beneficial to improving production efficiency and improving processing quality.

[0039] Furthermore, if Figure 3 and Figure 7 As shown, the longitudinal movement assembly 1 is provided with a clamping block 153, and the clamping block 153 and the movable seat 152 are relatively fixedly connected by fasteners, and the synchronous belt 14 is clamped between the clamping block 153 and the movable seat 152. Specifically, the clamping block 153 is formed with four through holes, and the bottom of the movable seat 152 is formed with four screw holes. Four screws are provided to pass through the above-mentioned four through holes respectively and are respectively screwed with the above-mentioned four screw holes, so that the synchronous belt 14 is clamped by the locking force of each of the above-mentioned screws, so that the movable seat 152 can be reliably fixed relatively to the synchronous belt 14. The above-mentioned screws are located on the left and right sides of the synchronous belt 14. In other words, the above-mentioned screws do not pass through the synchronous belt 14, so it will not affect the service life of the synchronous belt 14.

[0040] Furthermore, if Figure 3 and Figure 7 As shown, the clamping block 153 is arranged on the inner side of the synchronous belt 14, and the movable seat 152 is arranged on the outer side of the synchronous belt 14. Fig.11 As shown, the clamping block 153 is formed with a tooth portion 1531 for adapting to the tooth shape of the synchronous belt 14, that is, the tooth portion 1531 is adaptively connected to the tooth shape of the synchronous belt 14, thereby avoiding relative slippage between the clamping block 153 and the synchronous belt 14.

[0041] Furthermore, if Figure 3 and Figure 7 As shown, the bottom of the longitudinal moving table 12 is respectively installed with a cylinder support plate 151 and a baffle 154 for limiting the movable seat 152 through corresponding screws, and the feed cylinder 15 is installed on the cylinder support plate 151 through fasteners, specifically, the front end of the cylinder body of the feed cylinder 15 is abutted against the rear side of the cylinder support plate 151 and is installed and connected through corresponding screws, the feed cylinder piston rod 1501 is arranged through the cylinder support plate 151, and the movable seat 152 is arranged between the cylinder support plate 151 and the baffle 154; through the above arrangement, when the feed cylinder piston rod 1501 is extended, the movable seat 152 moves relatively to and abuts against the baffle 154, and when the feed cylinder piston rod 1501 is retracted, the movable seat 15 2 relatively moves toward and abuts against the cylinder support plate 151, so when the grinding wheel 33 is driven by the longitudinal movement servo motor assembly 11 to track the glass plate 99, the movable seat 152 and the baffle plate 154 are reliably relatively positioned by the thrust of the feed cylinder 15, or the movable seat 152 and the cylinder support plate 151 are reliably relatively positioned by the pulling force of the feed cylinder 15, which is conducive to improving the accuracy of the grinding wheel 33 when it is driven by the longitudinal movement servo motor assembly 11 to track the glass plate 99. The movable stroke of the movable seat 152 between the cylinder support plate 151 and the baffle plate 154 can be measured in advance, so that the control system can accurately track the glass plate 99, and the piston of the feed cylinder 15 can be prevented from being easily damaged due to frequent collisions.

[0042] Furthermore, if Figure 2 , Figure 3 and Figure 7 As shown, the longitudinal moving assembly 1 is provided with a rear limit proximity switch 18 and a front limit proximity switch 19 for limiting the travel of the longitudinal moving platen 12 in the front-rear direction. The control system is electrically connected to the rear limit proximity switch 18 and the front limit proximity switch 19. Since the synchronous belt 14 is annular, it is necessary to limit the movable seat 152 and the clamping block 153 within the linear travel range. For example, Figure 3 In the illustrated embodiment, the front limit proximity switch 19 senses the front end bottom of the longitudinal movement platen 12, and the rear limit proximity switch 18 senses the outer wall of the cylinder body of the feed cylinder 15; when the rear limit proximity switch 18 or the front limit proximity switch 19 is triggered, the control system controls the longitudinal movement servo motor assembly 11 to stop working.

[0043] Furthermore, if Figure 2 , Figure 3 and Figure 7As shown, the longitudinal movement assembly 1 is provided with a rear limit block 16 and a front limit block 17, both of which are used to block the longitudinal movement platform 12 from exceeding the travel range in the front and rear directions. The rear limit block 16 and the front limit block 17 can be fixedly mounted on the base 13, and the limit range of the rear limit proximity switch 18 and the front limit proximity switch 19 for the longitudinal movement platform 12 is within the limit range of the rear limit block 16 and the front limit block 17 for the longitudinal movement platform 12. That is to say, assuming that the rear limit proximity switch 18 or the front limit proximity switch 19 fails accidentally, the longitudinal movement platform 12 can also be blocked by the rear limit block 16 or the front limit block 17 to improve safety.

[0044] Furthermore, if Figure 8 As shown, as described above, the longitudinal movement assembly 1 is provided with a base 13, and the longitudinal movement servo motor assembly 11 is fixedly mounted on the base 13 through a motor support. Figure 2 As shown, a first synchronous pulley 141 is coaxially installed on the output shaft of the longitudinal movement servo motor assembly 11. When the longitudinal movement servo motor assembly 11 includes a reducer, specifically, the first synchronous pulley 141 is installed on the output shaft of the reducer of the longitudinal movement servo motor assembly 11. The base 13 is rotatably connected to the second synchronous pulley 142. Specifically, the base 13 may be installed with a support shaft, and the above-mentioned support shaft is rotatably connected to the second synchronous pulley 142 through corresponding bearings. The first synchronous pulley 141 and the second synchronous pulley 142 support and connect the synchronous belt 14, so that the synchronous belt 14 is in a tensioned state, and the movable seat 152 and the clamping block 153 are specifically located on the upper part of the synchronous belt 14; when the longitudinal movement servo motor assembly 11 drives the first synchronous pulley 141 to rotate, the synchronous belt 14 can operate synchronously, and the above-mentioned transmission structure is simple and the cost is low.

[0045] Furthermore, if Fig. 9 As shown, the spindle assembly 3 includes a spindle housing 32. Figure 6 As shown, the spindle housing 32 is rotatably connected to a swing seat 34, and the swing seat 34 can swing around the axis of the grinding wheel 33, as shown in FIG. Figure 8 and Fig.12 As shown, the front and rear symmetrical center line of the grinding wheel 33 (i.e. Fig.12 The front and rear sides of the dotted line in the figure are respectively provided with stoppers 35 for contacting the glass plate 99, and the stoppers 35 are correspondingly arranged on the swing seat 34; Figure 2 As shown, the glass safety corner processing device of the present invention also includes a chamfering limit assembly 4, such as Figure 5As shown, the chamfer limit assembly 4 is provided with a support 41, a limit rod 43 and a rocker rod 44. The rocker rod 44 is installed on the rocker seat 34. Specifically, the lower end of the rocker rod 44 is formed with an external threaded portion, and the external threaded portion is installed and connected with the upper part of the rocker seat 34. The support 41 is installed on the transverse seat 22. The rocker rod 44 passes through the transverse seat 22 upward. The limit rod 43 is screwed to the support 41. The front and rear sides of the upper part of the rocker rod 44 are respectively provided with limit rods 43. In other words, the number of the support 41 and the limit rod 43 is set to two each. The limit rod 43 is respectively in contact with the rocker rod 44. Specifically, the two limit rods 43 are against the rocker rod 44, so that the stopper 35 cannot swing in the working state. Fig.13 As shown, when processing the front corner of the glass plate 99, as shown in Fig.14 As shown in FIG. 1 , when the front edge of the glass plate 99 contacts the stopper 35 located at the rear side of the front-rear symmetric center line of the grinding wheel 33, the stopper 35 blocks the glass plate 99 from further moving toward the grinding wheel 33. The relative position of the glass plate 99 and the grinding wheel 33 is limited. At this time, the front corner of the glass plate 99 is processed. Fig.18 As shown, similarly, the stopper 35 located on the front side of the front-to-back symmetrical centerline of the grinding wheel 33 can block the rear end of the glass plate 99; during the debugging process of the glass safety angle processing device of the present invention, the sizes of the chamfers 991 formed by the front and rear ends of the glass plate 99 may be inconsistent, and it is necessary to rotate the limit rod 43 respectively and swing the swing seat 34 to adjust the positions of the swing rod 44 and the stopper 35 relative to the axis of the grinding wheel 33 accordingly, but the two limit rods 43 are still maintained against the swing rod 44. For example, when the chamfer 991 of the front corner of the glass plate 99 is greater than the chamfer 991 of the rear corner of the glass plate 99, the stopper 35 located on the rear side of the front-to-back symmetrical centerline of the grinding wheel 33 is adjusted backward accordingly. Since the two stoppers 35 are both arranged on the swing seat 34, the stopper 35 located on the front side of the front-to-back symmetrical centerline of the grinding wheel 33 will be adjusted backward accordingly, so that the sizes of the chamfers 991 at the front and rear ends of the glass plate 99 can be made consistent. Of course, in some cases, if the chamfers 991 at the front and rear ends of the glass plate 99 need to be larger and smaller, this can also be achieved by adjusting the limit rod 43. The limit rod 43 is correspondingly threaded with a locking nut 45, and the locking nut 45 is abutted against the corresponding support 41. Therefore, when the limit rod 43 is rotated to adjust the position of the stopper 35, the locking nut 45 is rotated to abut against the side of the support 41 and the locking nut 45 is tightened, so that the position of the stopper 35 can be conveniently locked.

[0046] Furthermore, if Fig. 9 As shown, the swing seat 34 includes a swing ring 341, a connecting shell 342 and a support arm 343. The swing ring 341 is sleeved on the main shaft housing 32. Specifically, as shown in Fig. 9As shown, the spindle housing 32 is formed with an annular groove 321 and a limiting shoulder portion 322. The annular groove 321 is arranged below the limiting shoulder portion 322. Figure 6 As shown, a retaining ring 38 is installed in the annular groove 321, and the swing ring 341 is adapted to be arranged between the retaining ring 38 and the limiting shoulder 322, so that the swing ring 341 is relatively positioned with the spindle housing 32 in the axial direction of the grinding wheel 33. During the installation of the swing seat 34, the swing seat 34 can be upwardly sleeved onto the spindle housing 32, and then the retaining ring 38 is installed. The retaining ring 38 can be divided into two halves. The two halves of the retaining ring 38 are respectively inserted into the annular groove 321 and then fixed to the spindle housing 32 by corresponding screws. The above structure is reasonably arranged and easy to install; the upper end of the connecting shell 342 is connected to the swing ring 341, and the support arm 343 is installed at the connecting shell 342. At the lower end, the support arm 343 and the connecting shell 342 are arranged on the outside of the grinding wheel 33, the stopper 35 is arranged on the upper side of the support arm 343, and the connecting shell 342 is formed with a notch 3421 for exposing the grinding wheel 33. Through the above arrangement, since the stopper 35 and the grinding wheel 33 can both contact the glass plate 99, and the stopper 35 is arranged on the upper side of the support arm 343, the contact between the glass plate 99 and the support arm 343 can be avoided. The connection shell 342 is arranged on the outside of the grinding wheel 33, so that the swing seat 34 can bypass the grinding wheel 33 and support the stopper 35. By setting the notch 3421, the grinding wheel 33 can contact the glass plate 99. The above structure is reasonably arranged and easy to manufacture and install.

[0047] Furthermore, if Fig.10 As shown, a core shaft 351 is provided on the support arm 343, and the stopper 35 is set to be cylindrical. The stopper 35 is sleeved outside the corresponding core shaft 351, and the stopper 35 can rotate around the axis of the corresponding core shaft 351. The above arrangement is conducive to making the stopper 35 made of nylon, and the core shaft 351 and the support arm 343 can be made of steel, which can not only make the stopper 35 reliably supported, but also prevent the stopper 35 from damaging the glass plate 99.

[0048] like Fig.12 As shown, the above description is for a set of glass safety corner processing devices of the present invention arranged on the left side of the glass plate 99. In actual applications, the glass safety corner processing devices of the present invention are symmetrically arranged on both sides of the glass plate 99, so that the corners on the left and right sides of the glass plate 99 can be processed simultaneously.

[0049] In summary, the glass safety corner processing device of the present invention has a high degree of automation, which is beneficial to improving production efficiency and processing quality.
