Description

Technical Field

[0001] The present invention relates to the technical field of glass production assistance, and particularly relates to a rectifying device and method for improving the positioning accuracy of A-frames. Background Art

[0002] When processing glass, a manipulator needs to pick up plates from an A-frame loaded with a certain number of semi-finished glass products to be processed, and transport them to downstream processing equipment for processing. When the glass on the A-frame is picked up by the manipulator, the empty A-frame needs to be removed from the A-frame placement station, and another A-frame loaded with a certain number of semi-finished glass products to be processed is replaced. After the glass is processed and inspected, the manipulator transports the glass to the A-frame. The A-frame loaded with a certain number of finished glass products will be removed from the station, and an empty A-frame is replaced to continue loading the finished glass. The above actions are repeated in a cycle.

[0003] An important factor determining whether the processing position of the semi-finished glass to be processed on the downstream equipment is accurate is whether the position of the A-frame loaded with the semi-finished products is accurate at the A-frame placement station. If the rectifying and positioning of the A-frame at the A-frame placement station is inaccurate, the position of the A-frame at the station will shift. This will not only cause the manipulator to place the glass inaccurately at the plate placement position of the downstream processing equipment, affecting the processing quality, but more seriously, it will cause the glass to break directly after being picked up by the manipulator from the A-frame. For the same reason, if the rectifying and positioning of the A-frame at the station is inaccurate, the position of the A-frame at the station will shift, which will cause the manipulator to place the processed finished glass on the A-frame beyond the reference line. Seriously, the edge of the glass will exceed the effective surface of the A-frame. During the handling process, the glass will also be broken. Since the weight of the A-frame for loading unprocessed semi-finished glass or processed finished glass is about 530 kg, with such a weight, directly placing the A-frame on the station and manually adjusting its position is time-consuming and laborious, and the position adjustment is not accurate enough. Summary of the Invention

[0004] To solve the technical problems existing in the background art, the present invention proposes a regularizing device for improving the positioning accuracy of the A-frame, which includes a bottom plate and two groups of floating regularizing mechanisms, two groups of first positioning wheel sets, a second positioning wheel set and a positioning plate installed on the bottom plate. There is an A-frame placement station on the bottom plate. The two groups of floating regularizing mechanisms are located on the A-frame placement station and are equipped with support plates for supporting the A-frame. The two groups of first positioning wheel sets are respectively located on both sides of the A-frame placement station. The first cylinders in the two groups of first positioning wheel sets are drivingly connected to the first positioning wheels, and the first cylinders drive the first positioning wheels to approach the support plate to form abutments with both sides of the A-frame located on the support plate. The second positioning wheel set is located at one end of the A-frame placement station. The second cylinders in the second positioning wheel set are drivingly connected to the second positioning wheels, and the second cylinders drive the second positioning wheels to approach the support plate to form an abutment with the front end of the A-frame. The positioning plate is located at the other end of the two groups of floating regularizing mechanisms to form an abutment with the rear end of the A-frame.

[0005] Preferably, the bottom plate is composed of two plate bodies. The number of the second positioning wheel set and the positioning plate is two groups each. And the two groups of cylinder assemblies, two groups of first positioning wheel sets, two groups of second positioning wheel sets and two groups of positioning plates are respectively installed on the two plate bodies. There is an A-frame access channel between the two plate bodies, and the plate bodies are installed on the ground through fastening bolts.

[0006] Preferably, the floating regularizing mechanism includes two groups of cylinder assemblies and ball bearings. The two groups of cylinder assemblies are arranged in sequence along the width direction of the support plate, and the multiple cylinders included in each group of cylinder assemblies are arranged in sequence along the length direction of the support plate. Hemispherical grooves are opened at the bottom end of the support plate. The ball bearings are movably installed on the driving ends of the cylinders inserted into the hemispherical grooves, and the diameter of the hemispherical grooves is larger than the diameter of the ball bearings.

[0007] Preferably, it further includes a guiding plate fixedly installed on the bottom plate. The guiding plate is located between the support plate and the first positioning wheel set, and through grooves for the first positioning wheels to pass through are opened on the guiding plate.

[0008] Preferably, shock pads are fixed on both the positioning plate and the guiding plate.

[0009] Based on the above-mentioned regularizing device for improving the positioning accuracy of the A-frame, the present invention also proposes a regularizing method for improving the positioning accuracy of the A-frame, which includes the following steps:

[0010] S1. The cylinder assembly drives the support plate to rise horizontally until the support plate is located above the first positioning wheel set, and then the A-frame is transferred to the support plate.

[0011] S2. The cylinder assembly drives the two support plates to tilt so that the A-frame located on the support plate makes smooth front-back and left-right movements until the A-frame is in the A-frame placement station, and then the cylinder assembly drives the support plate to return to the horizontal state, and the rear end of the A-frame abuts against the positioning plate.

[0012] S3. The cylinder assembly drives the support plate to descend. Two groups of first cylinders drive two groups of first positioning wheels to clamp both sides of the A-shaped frame, and the second cylinder drives the second positioning wheel to abut against the front end of the A-shaped frame, completing the positioning and rectifying of the A-shaped frame.

[0013] In the present invention, the rectifying device and method for improving the positioning accuracy of the A-shaped frame adjust the position of the A-shaped frame located on the support plate through the provided floating rectifying mechanism. The adjustment method is simple and fast, and the positioning is more accurate. After the rectifying is completed, the A-shaped frame is fixed by the provided first positioning wheel group, second positioning wheel group and positioning plate, avoiding the A-shaped frame from shifting again during use.

[0019] Referring to Figures 1-3 , a rectifying device for improving the positioning accuracy of the A-shaped frame proposed by the present invention includes a bottom plate 1 and two groups of floating rectifying mechanisms 2 installed on the bottom plate 1. The bottom plate 1 has an A-shaped frame placement station, and the two groups of floating rectifying mechanisms 2 are located on the A-shaped frame placement station and are installed with a support plate 6 for supporting the A-shaped frame.

[0020] In the above embodiment, the floating rectifying mechanism 2 is used to position and rectify the A-shaped frame placed on the support plate 6. The floating rectifying mechanism 2 drives the support plate 6 to tilt forward and backward, left and right, so that the A-shaped frame completes smooth actions forward and backward, left and right on the support plate 6, and finally makes the A-shaped frame completely in the A-shaped frame placement station, thus ensuring the smooth progress of the subsequent glass transfer process.

[0021] It should be further noted that referring to Figure 4, the floating rectifying mechanism 2 includes two sets of cylinder assemblies 21 and balls 22. The two sets of cylinder assemblies 21 are arranged in sequence along the width direction of the support plate 6, and the multiple cylinders included in each set of cylinder assemblies 21 are arranged in sequence along the length direction of the support plate 6. A hemispherical groove 61 is formed at the bottom end of the support plate 6. The balls 22 are movably installed on the driving ends of the cylinders inserted into the hemispherical groove 61, and the diameter of the hemispherical groove 61 is larger than the diameter of the balls 22.

[0022] The process of the floating rectifying mechanism 2 driving the support plate 6 to tilt forward and backward and left and right is as follows: When the support plate 6 needs to tilt forward and backward, the cylinders arranged along the length direction of the support plate 6 and located in front of the support plate 6 rise, making the front of the support plate 6 high and the rear low. The A-shaped frame located on the support plate 6 will translate backward. Similarly, when the cylinders located behind the support plate 6 rise, making the front of the support plate 6 low and the rear high, the A-shaped frame located on the support plate 6 will translate backward on the support plate 6. When the cylinder group arranged along the width direction of the support plate 6 is high on the left and low on the right, the A-shaped frame translates on the support plate 6 toward the direction of the lower cylinder.

[0023] In addition, to ensure that the A-shaped frame does not shift during the process of the manipulator transferring the glass when the A-shaped frame is at the placement station, a rectifying device for improving the positioning accuracy of the A-shaped frame proposed by the present invention further includes two sets of first positioning wheel groups 3, second positioning wheel groups 4, and a positioning plate 5. The two sets of first positioning wheel groups 3 are respectively located on both sides of the placement station of the A-shaped frame. The first cylinders in the two sets of first positioning wheel groups 3 are drivingly connected to the first positioning wheels, and the first cylinders drive the first positioning wheels to approach the support plate 6 to form abutments with both sides of the A-shaped frame located on the support plate 6. The second positioning wheel group 4 is located at one end of the placement station of the A-shaped frame. The second cylinders in the second positioning wheel group 4 are drivingly connected to the second positioning wheels, and the second cylinders drive the second positioning wheels to approach the support plate 6 to form an abutment with the front end of the A-shaped frame. The positioning plate 5 is located at the other end of the two sets of floating rectifying mechanisms 2 to form an abutment with the rear end of the A-shaped frame.

[0024] In the above embodiment, after the floating rectifying mechanism 2 drives the A-shaped frame to complete floating rectification, when the rear end of the A-shaped frame abuts against the positioning plate 5 and the second cylinders in the second positioning wheel group 4 drive the second positioning wheels to form an abutment with the front end of the A-shaped frame, the positioning of the A-shaped frame in the front and rear directions can be completed. The first cylinders in the two sets of first positioning wheel groups 3 drive the first positioning wheels to respectively form abutments with the left and right sides of the A-shaped frame, thereby realizing the positioning of the A-shaped frame in the left and right directions and preventing the A-shaped frame from shifting after completing the positioning and rectification.

[0025] In order to facilitate the placement of the A-frame on the support plate 6, the bottom plate 1 is composed of two plate bodies. The number of the second positioning wheel sets 4 and the positioning plates 5 is two groups each. And the two groups of floating rectifying mechanisms 2, the two groups of first positioning wheel sets 3, the two groups of second positioning wheel sets 4 and the two groups of positioning plates 5 are respectively installed on the two plate bodies. There is an A-frame access channel between the two plate bodies, and the plate bodies are installed on the ground through fastening bolts. The distance between the two plate bodies can be adjusted according to the width of the A-frame to meet the usage requirements of A-frames with different widths.

[0026] The specific process of placing the A-frame is as follows: A forklift can be used to place the A-frame on the support plate 6. The A-frame access channel can also be used as the forklift access channel, making the placement of the support plate 6 more convenient and fast.

[0027] In addition, it also includes a guide plate 7 fixedly installed on the bottom plate 1. The guide plate 7 is located between the support plate 6 and the first positioning wheel set 3, and a through groove for the first positioning wheel to pass through is provided on the guide plate 7. Shock pads are fixed on both the positioning plate 5 and the guide plate 7 to reduce the impact force suffered by the A-frame when colliding with the guide plate 7 or the positioning plate 5 during positioning and rectifying.

[0028] Based on a rectifying device for improving the positioning accuracy of the A-frame proposed by the present invention, a rectifying method for improving the positioning accuracy of the A-frame is also proposed. Refer to Figure 5 , which includes the following steps: S1. The cylinder assembly 21 drives the support plate 6 to rise horizontally until the support plate 6 is above the first positioning wheel set 3, and then the A-frame is transferred to the support plate 6.

[0029] S2. The cylinder assembly 21 drives the two support plates 6 to tilt so that the A-frame located on the support plate 6 makes smooth forward-backward and left-right movements until the A-frame is in the A-frame placement station, and then the cylinder assembly 21 drives the support plate 6 to return to the horizontal state, and the rear end of the A-frame abuts against the positioning plate 5.

[0030] S3. The cylinder assembly 21 drives the support plate 6 to descend. The two groups of first cylinders drive the two groups of first positioning wheels to clamp the two sides of the A-frame, and the second cylinder drives the second positioning wheel to abut against the front end of the A-frame to complete the positioning and rectifying of the A-frame.

[0031] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
