Description

Technical Field

[0001] The utility model relates to the technical field of glass edge grinding machines, in particular to a laminated glass edge grinding device. Background Art

[0002] Laminated glass, also known as interlayer glass, is a composite glass product made of two or more pieces of glass with one or more layers of organic polymer interlayer sandwiched between them. After special high-temperature pre-pressing and high-temperature and high-pressure process treatment, the glass and the interlayer are permanently bonded together. The edges of rectangular laminated glass are generally burred after production. In order to remove the burrs on the edges of the glass and facilitate subsequent use, a glass edge grinder is usually used to grind the edges of the glass to make it smooth and flat.

[0003] For example, the patent document with application number 202222909838.5 discloses a laminated glass edge grinding device, and the utility model relates to a laminated glass edge grinding device, including a frame and a placing table, a clamping mechanism, an adjusting mechanism, a grinding mechanism and a controller installed on the frame. There are grinding mechanisms on the front, back, left and right sides of the placing table. The clamping mechanism and the adjusting mechanism are above the placing table. The grinding mechanism includes a linear motor, a first cylinder and a grinder. The grinder is installed at the output end of the first cylinder. The first cylinder is installed on the mover of the linear motor. The controller is electrically connected to the linear motor, the first cylinder, the grinder, the clamping mechanism and the adjusting mechanism. The utility model controls the operation of the first cylinder through the controller, so that the grinding wheel working end of the grinder contacts the glass and grinds. The linear motor The mover of the machine drives the first cylinder to perform linear motion, and grinds the four sides of the laminated glass at the same time, which saves time and has high production efficiency. However, the laminated glass edge grinding device requires manual calibration and positioning to make the edge of the glass contact with the grinder when clamping and grinding the rectangular laminated glass. Repositioning will inevitably cause the device to tilt and affect the edge grinding flatness of the laminated glass. At the same time, long-term grinding processing will increase the workload of workers. The device can only clamp and grind rectangular laminated glass of specified models, and it is difficult to position, clamp and grind rectangular laminated glass of different models. At the same time, the existing grinding device can only clamp the edge of the material, and cannot control the clamping force. The material may be damaged due to excessive clamping force during the positioning and clamping process.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a laminated glass edge grinding device is proposed. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-Figure 2 As shown, a laminated glass edge grinding device includes a fixed base 1, and four limiting structures 200 are evenly distributed around the outer surface of the fixed base 1, and the limiting structure 200 includes a limiting slide rail 2 arranged around the outer surface of the fixed base 1. The advantage of this arrangement is that through the arrangement of the limiting slide rail 2, the sliding direction of the synchronous motor 202 can be limited when it moves, ensuring that the sliding of the linear motor 205 is stable, and no deviation will occur when the grinding structure 206 is used to grind the laminated glass.

[0024] Furthermore, a sliding bushing 207 is slidably installed on the outer surface of the limiting slide rail 2, and a linear motor 205 is arranged on the upper surface of the sliding bushing 207. The advantage of this arrangement is that, through the arrangement of the sliding bushing 207, the wear of the linear motor 205 caused by the contact between the linear motor 205 and the limiting slide rail 2 can be avoided when the linear motor 205 slides with the limiting slide rail 2.

[0025] Furthermore, a grinding structure 206 is installed on the upper end surface of the linear motor 205, and the grinding structure 206 is composed of a telescopic cylinder, a grinder and a water spray pipe. This setting is an existing device and will not be described in detail.

[0026] Furthermore, a buffer structure 209 is provided on the back surface of the grinding structure 206, and the buffer structure 209 is composed of a damping spring rod and an L-shaped plate, and an electromagnetic relay 210 is provided on the back surface of the L-shaped plate of the buffer structure 209. The advantage of this arrangement is that the buffer structure 209 can buffer the extrusion force caused by the transmission structure 208 through the compression of the damping spring rod when the grinding structure 206 is in contact and positioned with the four sides of the laminated glass, thereby avoiding damage to the edge of the glass due to excessive pressure. Through the setting of the electromagnetic relay 210, the magnetic force generated by the grinding structure 206 can be started to magnetically fix the damping spring rod when it is working, thereby offsetting the thrust generated by the grinding of the grinding structure 206, thereby avoiding the shaking of the damping spring rod that affects the normal grinding of the grinder.

[0027] Furthermore, a connecting plate 201 is fixedly installed at one end of the limiting slide rail 2 away from the fixed base 1, and a transmission structure 208 is arranged in the middle of the side of the surface of the connecting plate 201 away from the limiting slide rail 2. The advantage of this arrangement is that, through the arrangement of the transmission structure 208, after the laminated glass to be polished is placed on the placement platform 3, the synchronous motor 202 is driven to make the transmission block 204 installed on the surface of the spiral transmission rod 203 move inward along the limiting slide rail 2 until the grinders of the four grinding structures 206 contact the edge of the laminated glass to complete the positioning and installation of the laminated glass. This structure enables the edge grinding device to grind laminated glass of different models and sizes while also speeding up the positioning speed of the laminated glass, saving the time of manual positioning and increasing the efficiency of edge grinding.

[0028] Furthermore, the transmission structure 208 includes a synchronous motor 202 which is arranged through the middle of the surface of the connecting plate 201, and a spiral transmission rod 203 is arranged at the output end of the synchronous motor 202, a transmission block 204 is spirally installed on the outer surface of the spiral transmission rod 203, and the upper surface of the transmission block 204 and the lower surface of the linear motor 205 are arranged to be fixedly connected. The advantage of this arrangement is that through the arrangement of the spiral transmission rod 203, the linear motor 205 can be driven forward or backward by spiral transmission to complete the positioning and clamping of the laminated glass.

[0029] Furthermore, a support frame 4 is provided on the front end surface of the fixed base 1, and a clamping structure 401 is fixedly provided through the rear end surface of the support frame 4, the clamping structure 401 is composed of a telescopic cylinder and a pressure plate, and the telescopic cylinder is fixedly connected to the support frame 4 through the telescopic cylinder, and the pressure plate is fixedly connected to the lower end of the telescopic cylinder. The advantage of this arrangement is that, through the arrangement of the clamping structure 401, after the laminated glass is positioned, the telescopic cylinder can be used to drive the pressure plate to fix it on the surface of the placement platform 3.

[0030] like Figure 3-Figure 4 As shown, a placement platform 3 is provided on the bottom surface of the fixed base 1, and four limiting slide grooves 301 are evenly distributed on the outer circular surface of the upper end of the placement platform 3. The advantage of this arrangement is that, through the arrangement of the limiting slide grooves 301, when the clamping structure 401 presses the laminated glass, the downward sliding direction of the connecting ring 302 can be limited to avoid the displacement of the connecting ring 302 during the sliding process.

[0031] Furthermore, a reset structure 300 is provided on the outer circular surface of the placement platform 3, and the number of reset structures 300 evenly arranged on the outer circular surface of the placement platform 3 is four. The reset structure 300 includes four connecting blocks 304 arranged on the outer circular surface of the placement platform 3, and the upper end surface of the connecting block 304 is slidably installed with a limit slide rod 305, and a compression spring 306 is provided on the lower end outer circular surface. The advantage of this arrangement is that through the arrangement of the compression spring 306, a supporting force can be provided for the connecting ring 302. After the clamping structure 401 releases the limit on the laminated glass, the compression spring 306 can also lift the laminated glass by resetting the top connecting ring 302 to facilitate the taking of the laminated glass.

[0032] Furthermore, a connecting ring 302 is provided on the upper end surface of the limiting slide rod 305, and a plurality of friction balls 303 are rotatably installed on the upper surface of the connecting ring 302, and a sliding connection is arranged between the connecting ring 302 and the inner wall surface of the limiting slide groove 301. The advantage of this arrangement is that, through the arrangement of the friction balls 303, the friction force generated by the movement of the laminated glass can be reduced when the spiral transmission rod 203 is used to position the laminated glass, thereby avoiding wear on the surface of the laminated glass caused by friction.

[0033] Working principle: When using the laminated glass edge grinding device, first, place the un-edge-ground rectangular laminated glass on the upper surface of the placement platform 3, and then start the four synchronous motors 202 at the same time to drive the four spiral transmission rods 203 to rotate, so that the transmission block 204 installed on the surface of the spiral transmission rod 203 moves inward along the limit slide rail 2 with the synchronous motor 202 with the sliding bushing 207 until the grinders of the four grinding structures 206 contact the edge of the laminated glass to adjust and position the laminated glass. The spring damping rod on the back of the grinding structure 206 compresses the extrusion force brought by the buffer transmission structure 208. While positioning the laminated glass, the laminated glass will roll and rub with the friction ball 303. To reduce the wear caused by friction, after positioning is completed, the electromagnetic relay 210 is first started to generate magnetic attraction to adsorb and fix the buffer structure 209, and then the clamping structure 401 is started, so that the telescopic cylinder drives the compression to contact the upper surface of the laminated glass and press it down. At the same time, the connecting ring 302 will slide down along the limiting slide groove 301 due to the pressure until the friction ball 303 is flush with the placement platform 3 so that the laminated glass and the placement platform 3 are completely in contact. At the same time, the compression spring 306 supports the connecting ring 302 by compression. After the clamping structure 401 releases the limit on the laminated glass after grinding, the compression spring 306 lifts the connecting ring 302 by resetting to facilitate the removal of the laminated glass. This is the working principle of the laminated glass edge grinding device.
