[0053] The specific implementation of the embodiment of the utility model is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the utility model, and is not used to limit the embodiment of the utility model.

[0054] Figure 1 It is a structural schematic diagram of a push edge limiting device for glass cleaning and feeding according to an embodiment of the utility model. Figure 3 is based on Figure 1 A magnified schematic diagram of area B. Figure 1 and Figure 3 In the embodiment, the edge pushing and limiting device may include a limiting guide assembly, a first edge pushing assembly and a second edge pushing assembly. Specifically, the first edge pushing assembly may include a first edge pushing column 16 and a first moving assembly.

[0055] The limiting guide assembly is arranged on one side of the feeding conveyor line 3, and is used to limit and guide one of the side edges of the glass. The first edge-pushing assembly is arranged on the other side of the feeding conveyor line 3, and the first edge-pushing assembly is located at the conveying front end of the limiting guide assembly. The output end of the first moving assembly is connected to the first edge-pushing column 16, and is used to drive the first edge-pushing column 16 to move to push the glass close to the limiting guide assembly. The second edge-pushing assembly is arranged on the other side of the feeding conveyor line 3, and is located at the conveying rear end of the first edge-pushing assembly, and is used to push the glass so that one of the side edges of the glass fits with the limiting guide assembly.

[0056] After the manipulator clamps the glass onto the loading conveyor line 3, the loading conveyor line 3 drives the glass to move along the conveying direction. When the other side of the glass moves to face the first side-pushing column 16, that is, when the side of the glass close to the first side-pushing column 16 is opposite to the first side-pushing column 16, the first moving assembly is started. Specifically, facing here generally means that the end of the glass (the side perpendicular to the conveying direction) just passes the first side-pushing column 16 by a short distance. The first moving assembly drives the first side-pushing column 16 to move to contact the other side of the glass, and pushes the glass to move a distance along the position-limiting guide assembly and reset, that is, pre-pushing. When the glass continues to move to its other side and faces the first side-pushing column 16 and the second side-pushing assembly, that is, when the second side-pushing assembly and the first side-pushing column 16 are respectively located near the front and rear ends of the glass, the first moving assembly and the second side-pushing assembly are started synchronously. Specifically, the front and rear ends of the glass mentioned here are relative to the conveying direction of the glass, the front side is the front end, and the rear side is the rear end. The first edge-pushing column 16 and the second edge-pushing assembly move synchronously to contact the other side of the glass, so that one side of the glass contacts and fits with the limiting guide assembly, and the limiting guide assembly guides and limits the conveying of the glass, so that the glass can be more stable and reliable in the subsequent conveying process. Specifically, after the edge-pushing is completed, the first moving assembly and the second edge-pushing assembly are reset to wait for the next edge-pushing operation of the glass.

[0057] In the conventional glass edge-pushing structure, a plurality of fixed guide pillars are generally arranged on one side of the conveyor line, and a plurality of guide pillars that can push the glass to move are symmetrically arranged on the other side of the conveyor line. However, when there is a certain inclination when the glass is loaded, the glass is easily stuck between two of the guide pillars when the multiple guide pillars on the other side of the conveyor line push the glass, which leads to low efficiency and poor reliability of glass conveying. In this embodiment of the utility model, the first edge-pushing pillar 16 is used for preliminary pre-pushing and the second edge-pushing component is used for synchronous pushing, which can effectively reduce the risk of glass getting stuck, thereby improving the efficiency and reliability of glass conveying.

[0058] In this embodiment of the present invention, if Figure 1As shown, the position limiting guide assembly may include multiple groups of guide posts 7. Specifically, the multiple groups of guide posts 7 are rotatably arranged on one side of the feeding conveyor line 3, and are distributed in a linear array along the conveying direction of the feeding conveyor line 3.

[0059] The linear array distribution of the multiple groups of guide columns 7 can, on the one hand, limit one of the side edges of the glass and adjust the conveying angle of the glass; on the other hand, due to the rotatable setting of the guide columns 7, they can rotate when one of the side edges of the glass is in contact with them, so as to reduce the influence of friction on the conveying of the glass and achieve the purpose of guidance.

[0060] In this embodiment of the present invention, if Figure 3 As shown, the first moving assembly may include a first driving cylinder 18 and a first push plate 17 .

[0061] The first driving cylinder 18 is arranged at the other side of the feeding conveyor line 3 , the first push plate 17 is arranged at the output end of the first driving cylinder 18 , and the first push side column 16 is arranged at one end of the first push plate 17 away from the first driving cylinder 18 .

[0062] When it is necessary to pre-push the glass, the first driving cylinder 18 is started, and the first driving cylinder 18 drives the first push plate 17 to move. Since the first push column 16 is arranged at one end of the first push plate 17 away from the first driving cylinder 18, the first push column 16 first abuts against the other side of the glass and pushes the glass to move in the direction close to the guide column 7, effectively adjusting the position and angle of the glass conveying to avoid subsequent jamming and the like. After pushing the glass to move a preset distance, the first driving cylinder 18 drives the first push plate 17 and the first push column 16 to reset, waiting for the subsequent push with the second push assembly.

[0063] In this embodiment of the utility model, considering that friction will be generated when the glass contacts the first side-pushing column 16 , in order to reduce the influence of the friction on the glass transportation, the first side-pushing column 16 is rotatably connected to the first push plate 17 .

[0064] In this embodiment of the present invention, if Figure 2 As shown, the second edge-pushing assembly may include a plurality of groups of second edge-pushing columns 15 and a second moving assembly.

[0065] Multiple groups of second side-pushing columns 15 are distributed in a linear array along the other side of the loading conveyor line 3. The output end of the second moving component is connected to the multiple groups of second side-pushing columns 15 to drive the multiple groups of second side-pushing columns 15 to move synchronously to push the glass to move.

[0066] When the glass moves to the other side thereof and faces the first side-pushing column 16 and the plurality of second side-pushing columns 15, the first driving cylinder 18 and the second moving assembly are started, so that the first side-pushing column 16 and the plurality of second side-pushing columns 15 are respectively in contact with the other side of the glass, and the glass is pushed to move to one side thereof and in contact with the plurality of guide columns 7. The first side-pushing column 16 and the plurality of second side-pushing columns 15 are used to push the glass synchronously, that is, to push the front and rear ends of the glass respectively, so that the stability and effect of the movement of the glass as a whole along the guide columns 7 can be improved, that is, the stability and reliability of the glass edge pushing can be improved.

[0067] In this embodiment of the present invention, if Figure 1 and Figure 2 As shown, the second moving assembly may include a second driving cylinder 12 and a second push plate 9 .

[0068] The second driving cylinder 12 is arranged on the other side of the feeding conveyor line 3 , the second push plate 9 is arranged at the output end of the second driving cylinder 12 , and a plurality of groups of second side-pushing columns 15 are arranged at one end of the second push plate 9 away from the second driving cylinder 12 .

[0069] When it is necessary to drive the multiple sets of second edge-pushing columns 15 to push the glass, the second driving cylinder 12 is started, and the second driving cylinder 12 drives the second push plate 9 to move. Since the second edge-pushing columns 15 are arranged at one end of the second push plate 9 away from the second driving cylinder 12, the multiple sets of second edge-pushing columns 15 can be in contact with the other side of the glass and push one side of the glass to fit with the multiple sets of guide columns 7.

[0070] In this embodiment of the present invention, if Figure 2 As shown, the shape of the second push plate 9 may include an L shape. Specifically, the second push plate 9 may include a plurality of groups of fixing holes 10 , a plurality of groups of push arms 13 and a plurality of groups of C-shaped plates 14 .

[0071] Multiple groups of fixing holes 10 are evenly arranged in the vertical section of the second push plate 9, one end of the push arm 13 is connected with the corresponding fixing hole 10 by bolts 11, and the other end of the push arm 13 extends out of the horizontal section of the second push plate 9. Multiple groups of C-shaped plates 14 are respectively arranged at the other ends of the multiple groups of push arms 13, and multiple groups of second push side columns 15 are respectively arranged inside the multiple groups of C-shaped plates 14.

[0072] The push arm 13 is fixedly connected to the second push plate 9 by means of a bolt 11 passing through the fixing hole 10, that is, the push arm 13 is detachably connected to the second push plate 9, and the corresponding push arm 13 can be installed according to the size of the glass, thereby effectively improving the versatility of the push edge.

[0073] In this embodiment of the utility model, considering that friction will be generated when the glass contacts the second side-pushing column 15 , in order to reduce the influence of the friction on the glass transportation, the second side-pushing column 15 is rotatably connected to the C-shaped plate 14 .

[0074] On the other hand, the utility model also provides a side-pushing and limiting system for glass cleaning and feeding. Specifically, the side-pushing and limiting system may include a feeding conveyor line 3, a mechanical arm, and a side-pushing and limiting device. Specifically, the feeding conveyor line 3 may include a first conveyor line 1 and a second conveyor line 2, and the side-pushing and limiting device may include a limiting guide assembly, a first side-pushing assembly, and a second side-pushing assembly. Specifically, the first side-pushing assembly may include a first side-pushing column 16 and a first moving assembly.

[0075] The second conveyor line 2 is arranged at the rear end of the conveying of the first conveyor line 1, and the second conveyor line 2 cooperates with the first conveyor line 1 to convey the glass. The robotic arm is arranged near the first conveyor line 1, and is used to grab and transfer the glass to the first conveyor line 1. The limiting guide assembly is arranged on one side of the feeding conveyor line 3, and is used to limit and guide one of the side edges of the glass. The first edge pushing assembly is arranged on the other side of the feeding conveyor line 3, and the first edge pushing assembly is located at the conveying front end of the limiting guide assembly. The output end of the first moving assembly is connected to the first edge pushing column 16, and is used to drive the first edge pushing column 16 to move to push the glass close to the limiting guide assembly. The second edge pushing assembly is arranged on the other side of the feeding conveyor line 3, and is located at the rear end of the conveying of the first edge pushing assembly, and is used to push the glass so that one of the side edges of the glass fits with the limiting guide assembly.

[0076] After the manipulator clamps the glass onto the loading conveyor line 3, the loading conveyor line 3 drives the glass to move along the conveying direction. When the other side of the glass moves to face the first side-pushing column 16, that is, when the side of the glass close to the first side-pushing column 16 is opposite to the first side-pushing column 16, the first moving assembly is started. Specifically, facing here generally means that the end of the glass (the side perpendicular to the conveying direction) just passes the first side-pushing column 16 by a short distance. The first moving assembly drives the first side-pushing column 16 to move to contact the other side of the glass, and pushes the glass to move a distance along the position-limiting guide assembly and reset, that is, pre-pushing. When the glass continues to move to its other side and faces the first side-pushing column 16 and the second side-pushing assembly, that is, when the second side-pushing assembly and the first side-pushing column 16 are respectively located near the front and rear ends of the glass, the first moving assembly and the second side-pushing assembly are started synchronously. Specifically, the front and rear ends of the glass mentioned here are relative to the conveying direction of the glass, the front side is the front end, and the rear side is the rear end. The first edge-pushing column 16 and the second edge-pushing assembly move synchronously to contact the other side of the glass, so that one side of the glass contacts and fits with the limiting guide assembly, and the limiting guide assembly guides and limits the conveying of the glass, so that the glass can be more stable and reliable in the subsequent conveying process. Specifically, after the edge-pushing is completed, the first moving assembly and the second edge-pushing assembly are reset to wait for the next edge-pushing operation of the glass.

[0077] In this embodiment of the present invention, the first conveyor line 1 and the second conveyor line 2 may include a structure known to those skilled in the art for two sets of conveyor wheels and conveyor belts to cooperate in conveying. Specifically, Figure 1 As shown, the first conveying line 1 and the second conveying line 2 can share one conveying wheel to improve conveying stability.

[0078] In this embodiment of the present invention, if Figure 1 As shown, the feeding conveyor line 3 may further include two groups of support seats 8, and the first edge pushing assembly and the second edge pushing assembly are respectively arranged on the two groups of support seats 8.

[0079] In this embodiment of the present invention, if Figure 1 As shown, the edge pushing and limiting system may further include a support rod 4 , a fixing rod 5 and a sensor 6 .

[0080] The support rod 4 is arranged on the side of the feeding conveyor line 3, one end of the fixing rod 5 is connected to the support rod 4, and the other end of the fixing rod 5 extends above the feeding conveyor line 3. The sensor 6 is arranged at the other end of the fixing rod 5 for identifying and locating the glass on the feeding conveyor line 3.

[0081] Before the glass needs to be pushed, the sensor 6 first identifies the real-time position of the glass, and drives the first pushing component and the second pushing component to cooperate in pushing the glass according to the identified signal, so that the pushing accuracy is higher.

[0082] Through the above technical scheme, the edge-pushing and limiting device and system for glass cleaning and loading provided by the utility model starts the first moving component to drive the first edge-pushing column 16 to pre-push the glass and reset it. Since the first edge-pushing column 16 is located at the front end of the limiting guide component, the first edge-pushing column 16 can preliminarily adjust the conveying angle and conveying position of the glass, and then drive the first moving component and the second edge-pushing component to push the glass synchronously so that one of the side edges of the glass is in contact with the limiting guide component, thereby realizing the edge-pushing and limiting of the glass. The method of using the first edge-pushing column 16 for preliminary pre-pushing and cooperating with the second edge-pushing component for synchronous pushing can effectively reduce the risk of glass getting stuck, thereby improving the efficiency and reliability of glass conveying.
