[0044] First aspect

[0045] The embodiments of the present application provide a glass conveying device, referring to Figures 1 to 8 As shown, the glass conveying device comprises a first conveying mechanism 1, a second conveying mechanism 2, a turnover mechanism 3 and a limiting mechanism 4. The first conveying mechanism 1 has a first conveying area, and the first conveying mechanism 1 can drive the glass to convey in the first direction in the first conveying area. The second conveying mechanism 2 has a second conveying area, and the second conveying mechanism 2 can drive the glass to convey in the second direction in the second conveying area. The plane where the second conveying area is located is different from the plane where the first conveying area is located. The turnover mechanism 3 is arranged between the first conveying mechanism 1 and the second conveying mechanism 2. When the turnover area of the turnover mechanism 3 corresponds to the glass conveyed by the first conveying area, the turnover mechanism 3 can turn the glass conveyed by the first conveying mechanism 1 to the plane where the second conveying area is located and convey it to the second conveying mechanism 2. The limiting mechanism 4 comprises a first limiting mechanism 41. The first limiting mechanism 41 can drive at least part of the first conveying mechanism 1 to move in the direction perpendicular to the first direction, so that the glass conveyed by the first conveying area corresponds to the turnover area.

[0046] Specifically, the first conveying mechanism 1 in the above has a first conveying area. The first conveying area can be, for example, Figure 1The glass in the first conveying region can be conveyed in the first direction by the first conveying mechanism 1, which can be a plurality of conveying wheels that carry the glass and drive the glass to move in the first direction after the conveying wheels rotate, or a conveying belt that conveys the glass in the first direction, or other conveying means, which are not limited here. The first conveying mechanism 1 can be provided with a first height adjusting structure at the bottom to adjust the height of the first conveying mechanism 1 according to actual needs.

[0047] The second conveying mechanism 2 has a second conveying region, and the plane of the second conveying region is different from the plane of the first conveying region, that is, the plane of the second conveying region is not the same as the plane of the first conveying region. For example, as shown in Figure 1 , the plane of the first conveying region is a horizontal plane, and the angle between the plane of the second conveying region and the plane of the first conveying region is 80 degrees. The second conveying mechanism 2 can drive the glass to move in the second direction in the second conveying region, which can be driven by the fourth conveying wheels 22 to move in the second direction in the second conveying region, or driven by a conveying belt to move in the second direction in the second conveying region, or other conveying means, such as Figure 1 and Figure 7 , the angle between the glass in the second conveying region and the horizontal plane is 80 degrees, and the lower end of the glass is located in the groove around the plurality of fourth conveying wheels 22 extending in the second direction provided on the second conveying mechanism 2, and the glass moves in the second direction after the plurality of fourth conveying wheels 22 rotate. The second direction can be the same as the first direction, or different from the first direction, such as Figure 1 , the second direction is the same as the first direction, so that the glass continues to move in the first direction after being flipped by the flipping mechanism 3, and the following examples are all based on the first direction and the second direction being the same. The bottom of the second conveying mechanism 2 can be provided with a second height adjusting structure to adjust the height of the second conveying mechanism 2 according to actual needs.

[0048] The aforementioned flipping mechanism 3 is positioned between the first conveying mechanism 1 and the second conveying mechanism 2. When the flipping area of ​​the flipping mechanism 3 corresponds to the glass conveyed by the first conveying area, the flipping mechanism 3 can flip the glass conveyed by the first conveying mechanism 1 to the plane of the second conveying area and then convey it to the second conveying mechanism 2. In other words, the glass on the first conveying mechanism 1 must first be moved so that it corresponds to the flipping area of ​​the flipping mechanism 3. Then, the flipping mechanism 3 flips the glass from the plane of the first conveying area to the plane of the second conveying area. Finally, the flipping mechanism 3 conveys the flipped glass to the second conveying mechanism 2 for conveying in the second direction. It is understood that the flipping mechanism 3 is equipped with a stop structure to abut the bottom of the flipped glass, thereby preventing the glass from slipping off the flipping mechanism 3. For example: see [link to relevant documentation]. Figure 1 and Figure 7 As shown, the flipping mechanism 3 is equipped with a row of third conveyor wheels 31 extending along a first direction. Each third conveyor wheel 31 has a circumferential recess. The bottom of the flipped glass is located within the recess of the row of third conveyor wheels 31. When a row of third conveyor wheels 31 rotates, it can convey the glass to the second conveying mechanism 2. A third height adjustment structure can be provided at the bottom of the flipping mechanism 3 to adjust its height according to the actual required height.

[0049] The first limiting mechanism 41 described above can drive at least a portion of the first conveying mechanism 1 to move in a direction perpendicular to the first direction, so that the glass conveyed in the first conveying area corresponds to the flipping area. That is, through the driving and limiting of the first conveying mechanism 1 by the first limiting mechanism 41, the glass conveyed in the first conveying area corresponds to the flipping area, thereby enabling the flipping area of ​​the flipping mechanism 3 to flip the glass conveyed by the first conveying mechanism 1. The first limiting mechanism 41 described above can be a driving cylinder, a motor, or other power mechanism, which is not specifically limited here.

[0050] Since the flipping area of ​​the flipping mechanism 3 is fixed, when a piece of glass of the first size is conveyed by the first conveying mechanism 1 and corresponds to the flipping area, the next time a piece of glass of the second size is conveyed by the first conveying mechanism 1, it cannot correspond to the flipping area (for example, the edge of the stop structure corresponding to the glass conveyed by the first conveying mechanism 1 is not on the same extension line as the stop side of the stop structure, i.e., there is a distance difference). As a result, the flipping mechanism 3 may not be able to be conveyed to the flipping area for flipping due to the obstruction of the stop structure, or the glass may break due to its own gravity after flipping.

[0051] In the embodiment, the first limiting mechanism 41 can move at least part of the first conveying mechanism 1 and limit the movement of the at least part of the first conveying mechanism 1, so that the different sizes of glass conveyed by the first conveying mechanism 1 can correspond to the overturning area of the overturning mechanism 3 with the movement of the first conveying mechanism 1, so that the overturning mechanism 3 can overturn the different sizes of glass conveyed by the first conveying mechanism 1, thereby being able to process different sizes of glass through the same processing line, thereby being able to reduce production cost and improve processing efficiency by reducing the switching of different processing lines. In addition, compared with the way of manually moving the glass on the first conveying mechanism 1 to make the glass on the first conveying mechanism 1 correspond to the overturning area of the overturning mechanism 3, the way of the application can reduce the probability of glass pollution caused by manual operation and even induce glass breakage problem, and can improve the processing efficiency.

[0052] In some embodiments, referring to Figures 3 to 5 As shown, the limiting mechanism 4 further comprises: a second limiting mechanism 42, two parts of the second limiting mechanism 42 are respectively arranged on both sides of the first conveying area along the first direction and can be respectively moved to change the distance between the two parts of the second limiting mechanism 42; wherein the first limiting mechanism 41 can drive at least part of the first conveying mechanism 1 and the second limiting mechanism 42 to move simultaneously along a direction perpendicular to the first direction, so that the two parts of the second limiting mechanism 42 and the space for accommodating the glass defined by the first conveying area correspond to the overturning area.

[0053] Specifically, the two parts of the second limiting mechanism 42 in the above are respectively arranged on both sides of the first conveying area along the first direction, so that the two parts of the second limiting mechanism 42 can abut against both sides of the glass on the first conveying area along the first direction, so as to limit the glass on the first conveying area in a direction perpendicular to the first direction. The two parts of the second limiting mechanism 42 in the above can be respectively moved to change the distance between the two parts of the second limiting mechanism 42, for example: the second limiting mechanism 42 comprises: a first part limiting structure 421 and a second part limiting structure 422, and the first part limiting structure 421 and the second part limiting structure 422 can be respectively moved towards each other or away from each other, so that the distance between the first part limiting structure 421 and the second part limiting structure 422 can be changed, thereby being able to limit different sizes of glass in a direction perpendicular to the first direction.

[0054] The first limiting mechanism 41 can drive at least part of the first conveying mechanism 1 and the second limiting mechanism 42 to move in the direction perpendicular to the first direction at the same time, so that the space for accommodating the glass defined by the two parts of the second limiting mechanism 42 and the first conveying area corresponds to the turnover area, that is, the glass is located in the space defined by the two parts of the second limiting mechanism 42 and the first conveying area, and since the first limiting mechanism 41 can drive at least part of the first conveying mechanism 1 and the second limiting mechanism 42 to move in the direction perpendicular to the first direction at the same time, the space defined by the two parts of the second limiting mechanism 42 and the first conveying area can be moved to a position corresponding to the turnover area, so that the glass located in the space defined by the two parts of the second limiting mechanism 42 and the first conveying area is moved to a position corresponding to the turnover area, and then the glass can be turned over by the turnover mechanism 3.

[0055] In the embodiment, the first limiting mechanism 41 can limit the glass on the first conveying area in the direction perpendicular to the first direction, thereby reducing the deviation of the glass, so that the alignment of the glass with the turnover area is more accurate.

[0056] In some embodiments, as shown in Figure 1 The first conveying mechanism 1 comprises the first part conveying mechanism 11 and the second part conveying mechanism 12 arranged in sequence, and the glass can be conveyed to the turnover mechanism 3 in sequence through the first part conveying mechanism 11 and the second part conveying mechanism 12; wherein the two parts of the second limiting mechanism 42 are arranged on the two sides of the second part conveying mechanism 12 along the first direction respectively, and the first limiting mechanism 41 can drive the second part conveying mechanism 12 and the second limiting mechanism 42 to move in the direction perpendicular to the first direction at the same time.

[0057] Specifically, the first conveying mechanism 1 comprises the first part conveying mechanism 11 and the second part conveying mechanism 12 arranged in sequence, and the glass can be conveyed to the turnover mechanism 3 in sequence through the first part conveying mechanism 11 and the second part conveying mechanism 12, wherein the length of the first part conveying mechanism 11 along the first direction can be the same as or different from the length of the second part conveying mechanism 12 along the first direction, so that the length of the first part conveying mechanism 11 and / or the second part conveying mechanism 12 along the first direction can be adjusted according to the actual conveying distance.

[0058] The two parts of the second limiting mechanism 42 are respectively arranged on the two sides of the second conveying mechanism 12 along the first direction, and the first limiting mechanism 41 can drive the second conveying mechanism 12 and the second limiting mechanism 42 to move along a direction perpendicular to the first direction at the same time. In this way, the glass is limited on the two sides of the second limiting mechanism 42 closer to the turnover mechanism 3, and the second limiting mechanism 42 closer to the turnover mechanism 3 is driven by the first limiting mechanism 41, so as to reduce the material consumption of the second limiting mechanism 42 and the driving force of the first limiting mechanism 41, thereby reducing the manufacturing cost and prolonging the service life of the first limiting mechanism 41.

[0059] In some embodiments, referring to Figures 1 to 6 The first conveying mechanism 11 and / or the second conveying mechanism 12 includes a conveying table, an air floating structure and a driving structure. The conveying table extends along the first direction. The air floating structure is arranged above the conveying table, and a side of the air floating structure away from the conveying table forms a first conveying area. The air floating structure can blow air to the first conveying area side to make the glass in the first conveying area float. The driving structure can drive the glass in the first conveying area in a floating state to convey along the first direction.

[0060] Specifically, the air floating structure blows air to the first conveying area side to make the glass in the first conveying area float, so as to form an air floating protective layer between the air floating structure and the glass, so that the glass can be conveyed without contacting the air floating structure. In this way, the probability of the glass being scratched due to direct contact between the glass and the first conveying area can be reduced. Here, the air blown by the air floating structure to the first conveying area side can come from an air blower or other structures, and the structure providing air for the air floating structure can be connected to the corresponding conveying mechanism or not connected to the corresponding conveying mechanism and connected to the air floating structure during use.

[0061] In some embodiments, referring to Figures 1 to 5 The air floating structure includes a plurality of air floating strips extending along the first direction respectively, and the plurality of air floating strips are parallel to each other. The driving structure includes a plurality of rows of conveying wheels arranged along the first direction respectively. The plurality of rows of conveying wheels can carry the glass in a floating state on the plurality of air floating strips and drive the glass to convey along the first direction after the conveying wheels rotate. Any row of conveying wheels is located between adjacent two air floating strips or located outside the plurality of air floating strips.

[0062] Specifically, the air floating structure includes a plurality of air floating strips extending along the first direction respectively, and the plurality of air floating strips are parallel to each other. In this way, the plurality of air floating strips can blow air to the glass respectively to make the glass in a floating state. Here, the plurality of air floating strips can be distributed at equal intervals or not at equal intervals.

[0063] The driving structure in the above includes: multiple columns of conveying wheels arranged along the first direction respectively, the multiple columns of conveying wheels being capable of carrying the multiple glass in the suspended state on the multiple air floating strips and driving the glass to convey along the first direction after the conveying wheels rotate. Thus, the upper surface of the conveying wheels can be higher than the upper surface of the air floating strips, so that the multiple columns of conveying wheels are capable of carrying the multiple glass in the suspended state on the multiple air floating strips and driving the glass to convey along the first direction after the conveying wheels rotate. Any one column of conveying wheels in the above is located between the adjacent two air floating strips or is located outside the multiple air floating strips, in other words, in the multiple columns of conveying wheels, all can be arranged outside the multiple air floating strips, all can be arranged inside the multiple air floating strips, or part can be arranged outside the multiple air floating strips and part can be arranged inside the multiple air floating strips.

[0064] In an embodiment, as shown in Figure 1 and Figure 2 The first conveying mechanism 11 includes: a first conveying table 111, a first air floating structure 112, and a first driving structure 113. The first conveying table 111 extends along the first direction; the first air floating structure 112 is arranged above the first conveying table 111, and the first air floating structure 112 includes: multiple first air floating strips 1121 extending along the first direction respectively, the multiple first air floating strips 1121 are parallel to each other, the side of the multiple first air floating strips 1121 away from the first conveying table 111 forms a first conveying area of the first conveying mechanism 11, and the multiple first air floating strips 1121 are capable of blowing air to the side of the first conveying area of the first conveying mechanism 11 to make the glass in the first conveying area of the first conveying mechanism 11 suspended under the condition of air provided by the first air blower; the first driving structure 113 is two columns of first conveying wheels extending along the first direction respectively and located on the two sides of the multiple first air floating strips 1121 in the first direction, and the two columns of first conveying wheels are capable of driving the glass in the suspended state on the first conveying area of the first conveying mechanism 11 to convey along the first direction to the second conveying mechanism 12 after the two columns of first conveying wheels rotate. As shown in Figure 1 and Figures 3 to 5As shown, the second conveying mechanism 12 comprises a second conveying table 121, a second air floating structure 122 and a second driving structure 123. The second conveying table 121 extends along the first direction. The second air floating structure 122 is arranged above the second conveying table 121 and comprises a plurality of second air floating strips 1221 extending along the first direction. The plurality of second air floating strips 1221 are parallel to each other. The plurality of second air floating strips 1221 away from one side of the second conveying table 121 form a first conveying area of the second conveying mechanism 12. The plurality of second air floating strips 1221 are capable of blowing air to the first conveying area of the second conveying mechanism 12 to suspend the glass on the first conveying area of the second conveying mechanism 12 under the air force provided by a second air blower 1222. The second driving structure 123 comprises two rows of second conveying wheels extending along the first direction and arranged on both sides of the plurality of second air floating strips 1221 along the first direction. The two rows of second conveying wheels are capable of driving the glass suspended on the first conveying area of the second conveying mechanism 12 to convey the glass to the turnover mechanism 3 along the first direction after rotating.

[0065] It should be noted that the conveying wheels (e.g., the first conveying wheels, the second conveying wheels, the third conveying wheels 31 and the fourth conveying wheels 22) are in direct contact with the glass. Therefore, in order to reduce the probability of scratching the glass by the conveying wheels, an elastic layer (e.g., a rubber layer, a silica gel layer, etc.) can be arranged on the outer side of the circumference of the conveying wheels.

[0066] In some embodiments, referring to Figures 3 to 5 As shown, the second limiting mechanism 42 comprises a first part limiting structure 421 and a second part limiting structure 422. The first part limiting structure 421 and the second part limiting structure 422 are respectively connected with a row of conveying wheels (e.g., the second conveying wheels) on the two sides opposite to each other. The first part limiting structure 421 and the second part limiting structure 422 are respectively arranged with a row of guide wheels 423 on the two sides opposite to each other. When the lower surface of the glass suspended on the first conveying area abuts against the conveying wheels, the two sides of the glass respectively abut against a row of guide wheels 423. In this way, the two rows of guide wheels 423 on the two sides of the first part limiting structure 421 and the second part limiting structure 422 close to each other can reduce the friction between the two sides of the glass and the first part limiting structure 421 and the second part limiting structure 422, so as to make the conveying process of the glass more smooth and stable.

[0067] In some embodiments, referring to Figures 3 to 5As shown, the first part limiting structure 421 and the second part limiting structure 422 are symmetrical about the middle line of the first direction in which the first part limiting structure 421 and the second part limiting structure 422 extend, and the first part limiting structure 421 and the second part limiting structure 422 have the same distance and opposite direction when they are moved respectively. Thus, the first part limiting structure 421 and the second part limiting structure 422 can be on the same line of extension along the first direction when the first limiting mechanism 41 is adjusted so that the middle line of the first direction of the overturning area of the overturning mechanism 3 is on the same line of extension along the first direction between the first part limiting structure 421 and the second part limiting structure 422, so that the glass conveyed by the first conveying area corresponds to the overturning area.

[0068] In some embodiments, referring to Figure 1 As shown, the glass conveying device can further include a position sensor arranged on one side of the second part conveying mechanism 12 close to one end of the overturning mechanism 3, and the position sensor is connected with the second part conveying mechanism 12 and the first limiting mechanism 41 respectively. When the glass is conveyed to the position of the second part conveying mechanism 12 corresponding to the overturning mechanism 3 for overturning, the position sensor sends the position information to the second part conveying mechanism 12 to stop conveying the glass, and then the first limiting mechanism 41 moves the second part conveying mechanism 12 and the second limiting mechanism 42 so that the glass between the two parts of the second limiting mechanism 42 and the second part conveying mechanism 12 is opposite to the overturning area, and then the second part conveying mechanism 12 continues to convey so that the overturning mechanism 3 can receive the glass conveyed by the second part conveying mechanism 12 and overturn it.

[0069] In some embodiments, referring to Figure 8 As shown, the glass conveying device can further include a touch screen connected with the first conveying mechanism 1, the second conveying mechanism 2, the overturning mechanism 3 and the limiting mechanism 4 respectively, and the touch screen is provided with a plurality of touch areas, and different touch areas correspond to controlling the limiting mechanism 4 to limit in different degrees to process glasses of different sizes. That is, when different touch areas are selected, the first conveying mechanism 1, the second conveying mechanism 2, the overturning mechanism 3 and the limiting mechanism 4 are connected to prepare for finishing, and the first part limiting structure 421 and the second part limiting structure 422 can know the actual size of the glass according to the selection of the touch area to move correspondingly so that the first part limiting structure 421 and the second part limiting structure 422 can fit the two sides of the glass along the first direction, and the first limiting mechanism 41 of the limiting mechanism 4 can determine the distance to be moved by the second part conveying mechanism 12 and the first part limiting structure 421 and the second part limiting structure 422 according to the actual size of the glass selected by the touch area to control the movement of the second part conveying mechanism 12 and the first part limiting structure 421 and the second part limiting structure 422.

[0070] It can be understood that the glass conveying device is provided with a control system, and the control system stores the direction and distance to be moved of the first part limiting structure 421 and the second part limiting structure 422 and the direction and distance to be moved of the second part conveying mechanism 12 corresponding to each size of glass. Thus, when a certain touch area is selected, the control system corresponding to the direction and distance to be moved is sent to the corresponding device.

[0071] In some embodiments, the angle between the plane where the first conveying area is located and the plane where the second conveying area is located is 70-130 degrees, such as 85 degrees.

[0072] In some embodiments, the bottom of the first conveying mechanism 1, the second conveying mechanism 2 and the turnover mechanism 3 can be respectively provided with a rack, and the height of the rack can be set according to actual needs. For example, in order to facilitate the staff to check the specific finishing condition of the glass on the glass conveying device, the height of the rack can be close to the height that the staff can check by bending over. And the finishing equipment (such as precision cutting and grinding equipment, cleaning and cleaning equipment and inspection and packaging equipment) can be respectively located on both sides of the glass conveying device.

In addition, compared with the way of manually moving the glass on the first transport mechanism 1 to make the glass on the first transport mechanism 1 correspond to the turnover area of the turnover mechanism 3, the way of the present application can reduce the probability of glass pollution caused by manual operation and even induce glass breakage problem, while improving processing efficiency.
