Description

Technical Field

[0001] The utility model relates to the field of auxiliary equipment for a hot-bending glass plate production line, and in particular to a hot-bending glass centering device. Background Art

[0002] At present, in the production process of hot-bent glass plates, straight glass plates are transformed into arc-shaped bent glass plates through the hot-bending process and placed on the conveyor line piece by piece. The conveyor line conveys the glass plates to the corresponding positions of the cleaning equipment. A glass plate lifting mechanism is provided at the end of the conveyor line. After the lifting mechanism pushes the glass plates upwards away from the conveyor line, the glass plates lifted by the lifting mechanism are transferred to the cleaning basket by the robotic arm. The cleaning basket is provided with lateral positioning grooves. The left and right ends of the glass plates are respectively inserted into the corresponding lateral positioning grooves to prevent the glass plates from shaking left and right in the cleaning basket. However, the glass plates on the conveyor line are often offset to the left or right. When the clamp at the end of the robotic arm picks up the offset glass plates and puts them into the cleaning basket, the glass plates may not be inserted into the cleaning basket due to misalignment. The glass plates may even be crushed by the robotic arm. Therefore, it is necessary to provide a device that can center and position the glass plates lifted by the lifting mechanism to ensure stable production. Summary of the invention

DETAILED DESCRIPTION

[0017] The utility model is further described below in conjunction with the accompanying drawings.

[0018] The heat-bending glass centering device of the utility model is as follows Figure 1 and Figure 2 As shown, it includes a gantry 1, a synchronization mechanism 4, a horizontal clamping cylinder 5, a left push arm 2 for pushing the glass plate 99 to the right, and a right push arm 3 for pushing the glass plate 99 to the left. The left push arm 2 and the right push arm 3 are slidably arranged on the gantry 1. Specifically, two upper and lower linear guide rails are installed on the front side of the gantry 1, and two first sliders are installed on the rear side of the left push arm 2. The two first sliders are respectively adapted to be slidably connected with the upper and lower linear guide rails. Two second sliders are installed on the rear side of the right push arm 3. The two second sliders are respectively adapted to be slidably connected with the upper and lower linear guide rails, so that the left push arm 2 and the right push arm 3 can move horizontally and linearly; as shown Figure 1 and Figure 2 As shown, the synchronization mechanism 4 includes a gear 41, a lower rack 42 and an upper rack 43, the gear 41 is rotatably connected to the gantry 1, specifically, a supporting shaft is installed on the front side of the gantry 1, the gear 41 is coaxially sleeved on the supporting shaft, a bearing is provided between the gear 41 and the supporting shaft, the lower rack 42 and the upper rack 43 are respectively meshed and connected to the two sides of the gear 41, the lower rack 42 is relatively fixedly connected to the left push arm 2, specifically, the left end of the lower rack 42 is installed on the left push arm 2 by corresponding screws, and the upper rack 43 is relatively fixedly connected to the right push arm 3, specifically, the right end of the upper rack 43 is installed on the right push arm 3 by corresponding screws; the cross-clamp cylinder 5 drives the gear 41 to rotate, during which, the piston rod of the cross-clamp cylinder 5 can be directly connected to the right push arm 3 or the left push arm 2, or the cross-clamp cylinder 5 can be directly connected to the lower rack 42 or the upper rack 43, that is, the cross-clamp cylinder 5 indirectly drives the gear to rotate.

[0019] The working principle of the centering device for hot-bent glass sheets of the utility model is briefly described as follows: Figure 3 and Figure 4 As shown, the glass plate conveyor line 9 moves the glass plate 99 forward to the position of the lifting mechanism. During this period, the glass plate 99 can pass under the gantry 1. The glass plate conveyor line 9 stops running, and the lift cylinder 961 of the lifting mechanism moves the lift rod 96 upward. Figure 4 As shown, the four push rods 96 push the glass plate 99 up, and the horizontal clamp cylinder 5 drives the gear 41 to rotate counterclockwise (in Figure 1In the visual direction), the gear 41 relatively drives the lower rack 42 and the left push arm 2 to move to the right. Synchronously, the gear 41 relatively drives the upper rack 43 and the right push arm 3 to move to the left. That is to say, the left push arm 2 and the right push arm 3 move toward each other synchronously. For example, if the glass plate 99 is located to the left, the left push arm 2 first contacts the left end of the glass plate 99, and then the left push arm 2 pushes the glass plate 99 to the right. Since the left push arm 2 and the right push arm 3 move toward each other synchronously, the right push arm 3 contacts the right end of the glass plate 99. At this time, the glass plate 99 supports the thrust of the horizontal clamping cylinder 5. The left push arm 2 and the right push arm 3 are both stopped from moving. At this time, the center line of the glass plate 99 in the left-right direction coincides with the center line between the left push arm 2 and the right push arm 3, that is, the glass plate 99 is centered in the left-right direction. If the width dimension of the glass plate 99 in the left-right direction changes or there is an error, since the left push arm 2 and the right push arm 3 move toward each other synchronously, when the glass plate 99 is clamped between the left push arm 2 and the right push arm 3, the center line of the glass plate 99 in the left-right direction coincides with the center line between the left push arm 2 and the right push arm 3. The difference is that the distance between the left push arm 2 and the right push arm 3 has changed. Figure 3 As shown, after the glass plate 99 is adjusted in position by the centering device of the utility model, the robot arm 98 drives the clamp 97 to move to the clamping position, and the clamp 97 clamps the glass plate 99 located on the top rod 96 front and back. Since the position of the clamp 97 is controlled by a program, the center line of the centered glass plate 99 in the left and right directions can always be correctly aligned with the clamp 97, that is, the glass plate 99 is prevented from being offset to the left and right on the clamp 97, so that the robot arm 98 combined with the clamp 97 can accurately insert the glass plate 99 into the lateral positioning groove of the cleaning basket, avoiding the situation where the glass plate 99 cannot be inserted into the cleaning basket due to left and right offset, which is conducive to stable production.

[0020] Furthermore, if Figure 2As shown, a finger cylinder 23 for longitudinally pushing and clamping the glass plate 99 is installed on the lower side of the left push arm 2, and two claws 221 are installed on the finger cylinder 23. Specifically, the finger cylinder 23 is provided with two clamping fingers, and the two claws 221 are respectively installed on the corresponding clamping fingers by screws. The ends of the claws 221 are installed with longitudinal clamping wheels 22 for contacting the edge of the glass plate 99, and the axis of the longitudinal clamping wheel 22 is extended in the up-down direction. Specifically, the longitudinal clamping wheel 22 is coaxially rotatably connected to the corresponding mandrel, and the upper end of the above-mentioned mandrel is passed through the corresponding claw 221, and the above-mentioned mandrel is positioned on the corresponding claw 221 through a shoulder structure combined with an elastic retaining ring for the shaft; through the above-mentioned arrangement, after the horizontal clamping cylinder 5 pushes and clamps the glass plate 99 in the left-right direction (i.e., horizontally) to center the glass plate 99 left and right, the finger cylinder 23 drives the front and rear two longitudinal clamping wheels 22 to move synchronously close to each other in the front-to-back direction, When the center line of the glass plate 99 in the front-to-back direction is offset relative to the finger cylinder 23, one of the longitudinal clamping wheels 22 will first contact the front edge or the rear edge of the glass plate 99. When both the front and rear longitudinal clamping wheels 22 contact the glass plate 99, the glass plate 99 supports the clamping pressure of the finger cylinder 23 and stops the longitudinal clamping wheels 22 from moving. Then the finger cylinder 23 drives the claws 221 to open and release the glass plate 99. At this time, the center line of the glass plate 99 in the front-to-back direction is aligned with the symmetric planes of the two clamping fingers of the finger cylinder 23. Then the horizontal clamping cylinder 5 drives the left push arm 2 and the right push arm 3 to separate to release the glass plate 99. The clamp 97 then clamps the glass plate 99 and takes it away. Through the above arrangement, the glass plate 99 is further adjusted to the center position on the push rod 96 to avoid the situation where the clamp 97 cannot clamp the glass plate 99 due to the excessive offset of the glass plate 99 on the push rod 96.

[0021] Furthermore, if Figure 2As shown, a left push wheel 21 for contacting the left end edge of the glass plate 99 is installed on the lower side of the left push arm 2, and the axis of the left push wheel 21 is extended in the up-down direction. The connection structure between the left push wheel 21 and the left push arm 2 can refer to the connection structure between the longitudinal clamping wheel 22 and the claw 221. The left push wheel 21 is distributed in the front-to-back direction. Specifically, the number of the left push wheels 21 can be set to two. A right push wheel 31 for contacting the right end edge of the glass plate 99 is installed on the lower side of the right push arm 3, and the axis of the right push wheel 31 is extended in the up-down direction. The right push wheel 31 is distributed in the front-to-back direction. Specifically, the number of the right push wheels 31 can be set to two. When the glass plate 99 is pushed and clamped by the longitudinal clamping wheel 22, the right push wheel 31 and the left push wheel 21 actually contact the glass plate 99. Since the left push wheel 21 and the right push wheel 31 are arranged in a front-to-back direction, the glass plate 99 can be prevented from rotating in a horizontal plane, that is, the horizontal rotation deviation of the glass plate 99 can be corrected, which is conducive to the mechanical arm 98 and the clamp 97 to accurately put the glass plate 99 into the cleaning basket later. Moreover, when the longitudinal clamping wheel 22 longitudinally pushes and clamps the glass plate 99, the right push wheel 31 and the left push wheel 21 guide the glass plate 99, which can also prevent the glass plate 99 from rotating horizontally. Moreover, the right push wheel 31 and the left push wheel 21 can roll relative to the glass plate 99. Figure 3 As shown, since the glass plate 99 is an arc-shaped curved glass plate, the edge of the glass plate 99 is curved, and by arranging the axis of the left push wheel 21 to extend in the vertical direction, the axis of the right push wheel 31 to extend in the vertical direction, and the axis of the longitudinal clamping wheel 22 to extend in the vertical direction, the left push wheel 21, the right push wheel 31 and the longitudinal clamping wheel 22 have a sufficient range in the vertical direction to contact the edge of the glass plate 99. The right push wheel 31, the left push wheel 21 and the longitudinal clamping wheel 22 can all be plastic wheels to avoid hitting the glass plate 99.

[0022] Furthermore, the finger cylinder 23 is located to the left of the left push wheel 21. In the front-to-back direction, the left push wheel 21 is located between the two claws 221. In other words, the claws 221 bypass the left push wheel 21, so that the longitudinal clamping wheel 22 can be located to the right of the left push wheel 21, so that the longitudinal clamping wheel 22 is closer to the center line of the glass plate 99 in the left and right directions. Therefore, although the finger cylinder 23 is set on one side, it can also avoid the situation where the glass plate 99 is difficult to push when the longitudinal clamping wheel 22 pushes and clamps the glass plate 99 longitudinally; since the finger cylinder 23 is located to the left of the left push wheel 21, interference between the finger cylinder 23 and the left push wheel 21 is avoided.

[0023] Furthermore, if Figure 1As shown, a buffer 6 for buffering the rightward movement of the left push arm 2 is installed on the gantry 1, so when the cross-clamping cylinder 5 pushes the glass plate 99, the left push arm 2 first hits the buffer 6. The buffering effect of the buffer 6 on the left push arm 2 makes the left push arm 2 move to the right more slowly, and then the left push wheel 21 contacts the left edge of the glass plate 99, thereby avoiding the left push wheel 21 from causing impact on the glass plate 99. When the left push wheel 21 and the right push wheel 31 release the glass plate 99, the buffer 6 resets itself through the internal spring structure.

[0024] Furthermore, if Figure 1 and Figure 2 As shown, the cylinder body of the cross-clamp cylinder 5 is fixed to the gantry 1, specifically, a cylinder support is installed on the gantry 1, the right end portion of the cylinder body of the cross-clamp cylinder 5 passes through the cylinder support, and the nut screwed to the right end of the cylinder body of the cross-clamp cylinder 5 clamps and fixes the cylinder support, and the piston rod of the cross-clamp cylinder 5 is installed and connected with the left push arm 2, specifically, the right end portion of the piston rod of the cross-clamp cylinder 5 passes through the left push arm 2, and the left push arm 2 is clamped and relatively fixed by two nuts screwed on the piston rod of the cross-clamp cylinder 5; through the above arrangement, when the piston rod of the cross-clamp cylinder 5 is extended, the cross-clamp cylinder 5 directly pushes the left push arm 2 to move to the right, and the lower rack 42 drives the gear 41 to rotate counterclockwise, and synchronously, the gear 41 drives the upper rack 43 to move to the left, thereby causing the right push arm 3 to move to the left synchronously, and the above-mentioned indirect drive structure for the gear 41 is relatively simple, so it is conducive to reducing costs.
