According to the technical scheme, the positioning assembly 10 is provided with the positioning table 11, the limiting blocks 12, the first adjusting blocks 13, the first mounting table 17 and the first driving device 15 by adopting the positioning assembly 10, the lamination assembly and the transferring assembly, and the lamination assembly comprises a plurality of lamination bins. On one hand, a plurality of middle indexes 111 are arranged on the positioning table 11, and the lamination bins are in one-to-one correspondence with the middle indexes 111, so that the number of the adjusted glass sheets is matched with the lamination bins, and a plurality of groups of lamination materials are carried out at the same time; on the other hand, the first adjusting block 13 and the limiting block 12 are respectively positioned on two opposite sides of the middle rotating position 111, and the first driving device 15 drives the first mounting table 17 to move so as to drive the first adjusting block 13 to slide along the same direction, the first adjusting block 13 approaches and moves away from the middle rotating position 111 to repeatedly push the glass sheets, and the limiting block 12 limits the glass sheets, so that the first adjusting block 13 and the limiting block 12 cooperate to form clamping of the glass sheets, thereby realizing positioning of the glass sheets and meeting the stacking azimuth requirement. Not only improves the flexibility of the device, greatly reduces manual operation, but also realizes automatic stacking of glass sheets and remarkably improves the automatic production efficiency.

As shown in fig. 1 and 2, the machine 1 is specifically used for installation and operation of other devices in a lamination machine. The positioning assembly 10 is used for positioning glass sheets, and the positioning table 11 is provided with at least one limiting block 12 and a first adjusting block 13 corresponding to each rotation position 111, and the limiting block 12 is used for limiting the glass sheets. Since the glass sheet may have any shape, such as a rectangle, triangle, pentagon, etc., the stopper 12 may have any shape that limits the side or angle of the glass sheet, such as a strip, and limits one side of the glass sheet; or bending the two connected side plates to limit the included angle of the glass sheets. In this embodiment, two limiting blocks 12 are adopted, so that the two limiting blocks 12 are respectively arranged at two adjacent sides at intervals, a larger limiting space is formed for the glass sheet, and a better positioning effect is achieved.

The first adjusting block 13 acts on the glass sheet, and the first adjusting block 13 is preferably long so as to enlarge the contact surface to the glass sheet, and has a good pushing effect. A limiting block 12 and a first adjusting block 13 are respectively positioned on two opposite sides of the middle position 111, and the first adjusting block 13 slides back and forth to approach and depart from the middle position 111, so that the glass sheet is pushed to realize positioning.

Because the positioning table 11 is provided with the plurality of first adjusting blocks 13 corresponding to the plurality of intermediate positions 111, if the first driving device 15 is used for driving the first adjusting blocks 13 respectively, the structure is complex and the cost is high. Therefore, as shown in fig. 2, the first mounting table 17 is adopted, a slide rail is mounted on the upper surface of the first mounting table 17 facing the positioning table 11, and a slide block in sliding fit with the slide rail is mounted on the lower surface of the positioning table 11 facing the first mounting table 17 through a mounting block, so that the first mounting table 17 is in sliding connection with the positioning table 11. Meanwhile, the first adjusting blocks 13 are slidably mounted on the first mounting table 17, and the first mounting table 17 is driven to slide along a first direction by the first driving device 15, wherein the direction can be the direction of one side edge of the glass sheet or the direction of one corner. Taking a glass sheet as an example, the first direction is set to be the width direction of the glass sheet. The sliding of the first mounting table 17 is driven by the force, so that the plurality of first adjusting blocks 13 slide along the same direction as the sliding direction of the first mounting table 17 under the action of the inertia force, thereby realizing the simultaneous positioning and adjustment of the glass sheets in the plurality of middle indexes 111. The first driving device 15 is preferably a cylinder having a telescopic rod, the free end of which is connected to the first mounting table 17, since the first mounting table 17 is driven to slide back and forth.

Of course, the first adjusting block 13 may be rotated instead of being slidably mounted. In the case of rotation, the first driving device 15 may adopt a motor and a connecting rod, so that one end of the connecting rod is connected with the first adjusting block 13, and the connecting rod is driven by the motor to turn the first adjusting block 13 back and forth, so that the glass sheet can be pushed.

In addition, a plurality of buffer members are further arranged on the outer side edge of the first mounting table 17 along the length direction of the glass sheet, the first positioning table 11 is provided with a baffle plate corresponding to the buffer members, and the buffer ends of the buffer members are arranged corresponding to the baffle plates, so that buffering of the first mounting table 17 is formed in the process that the first mounting table 17 slides towards the glass sheet along the width direction, and damage of the glass sheet caused by overlarge acting force is prevented.

Further, as shown in fig. 1, the positioning assembly 10 further includes a plurality of second adjusting blocks, a second mounting table and a second driving device, the second mounting table is disposed below the positioning table 11 and is slidably connected with the positioning table 11, the second mounting table is provided with a second guiding opening corresponding to the second adjusting block 14, the second adjusting block is disposed on one side of the middle rotating position 111 adjacent to the first adjusting block, the second adjusting block is disposed on the second guiding opening and is slidably mounted on the second mounting table, and the second driving device is connected with the second mounting table to drive the second mounting table to move so as to drive the second adjusting block 14 to slide along the same direction. Since the glass sheet is generally polygonal in shape, the glass sheet can be pushed from another direction by the second adjustment block 14, even if the second adjustment block 14 is moved in a second direction, which may be the length direction of the glass sheet. Therefore, in the process of adjusting and positioning the glass, the second adjusting block 14 is matched with the first adjusting block 13, and the glass sheet is pushed and adjusted from two adjacent side directions at the same time, so that the glass sheet is clamped, and the positioning effect of the glass sheet is improved. Of course, the second adjusting block 14 may be mounted on a side spaced from the first adjusting block 13, and the second adjusting block 14 and the first adjusting block 13 may be disposed in different directions of the glass sheet.

By arranging the second mounting table, a plurality of second adjusting blocks 14 are integrally mounted on the second mounting table, so that the second driving device 16 can drive the second adjusting blocks 14 simultaneously by driving the second mounting table. The same as the first mounting table 17, a sliding fit sliding rail and a sliding block are adopted, so that the sliding rail is mounted on the second mounting table along the second direction, and the sliding block is connected with the positioning table 11 to realize sliding connection of the second mounting table and the positioning table 11. In order to reduce the friction resistance between the second adjusting block 14 and the second mounting table, the second adjusting block 14 is connected with a sliding block through a connecting block, and the sliding block is matched with a sliding rail to realize the sliding mounting of the second adjusting block 14. The second driving device 16 is preferably an air cylinder, the free end of the telescopic rod of which is connected with the second mounting table, and a plurality of buffering members are arranged between the second mounting table and the positioning table 11 so as to buffer the sliding of the second mounting table.

As shown in fig. 2, the positioning assembly 10 further includes a guide post 172, the first mounting table 17 is provided with a mounting ear 171, the mounting ear 171 is provided with a guide hole passing therethrough, the guide post 172 is disposed through the guide hole and is in clearance fit with the guide hole, and one end of the guide post 172 is connected with the first adjusting block. By arranging the guide column 172, the guide effect of the first adjusting block 13 in the sliding process is increased, so that the first adjusting block 13 slides under the guide effect of the guide column 172, and the accuracy and stability of the sliding direction of the first adjusting block 13 are enhanced. It is easily conceivable that the second mounting tables are also provided with mounting lugs 171 corresponding to the second adjustment blocks 14, the mounting lugs 171 are provided with guide holes penetrating through the mounting lugs, the guide posts 172 are penetrated in the guide holes and are in clearance fit with the guide holes, and the second adjustment blocks 14 are connected with one ends of the guide posts 172, so that the sliding guiding action of the second adjustment blocks 14 is enhanced.

Further, as shown in fig. 2, the positioning table 11 is provided with a plurality of balls 113 at intervals protruding from the positioning table 111. This is because the glass sheet is placed on the center index 111 and rubbed against the surface of the positioning table 11 during the adjustment of the positioning unit 10, and is easily broken due to uneven stress. Therefore, the positioning table 11 is provided with a plurality of balls 113 which are spaced from each other at the position corresponding to the middle position 111, the glass sheet is arranged on the balls 113, and the movement of the glass sheet is driven by the rotation of the balls 113, so that the friction generated in the movement process of the glass sheet is obviously reduced, and the damage is avoided. And the ball 113 is arranged on the boss, and then the boss is arranged on the middle position 111, so that the installation is convenient. At the same time, a sensor is also provided in the intermediate position 111 to detect whether there is a glass sheet in the intermediate position 111.

As shown in fig. 3, the lamination assembly 20 further includes a base 21, a mounting plate 221 and a plurality of pairs of limiting plates 222, the base 21 is disposed on the machine table 1, the mounting plate 221 is disposed on the base 21, the plurality of pairs of limiting plates 222 are mounted on the mounting plate 221, two limiting plates 222 of any pair of limiting plates 222 are disposed opposite to each other, and the two limiting plates 222 and the mounting plate 221 enclose to form a lamination bin 22. With only one mounting plate 221 and a pair of limiting plates 222, one lamination magazine 22 is formed; under the condition of using one mounting plate 221 or a plurality of pairs of limiting plates 222, a plurality of lamination bins 22 which are arranged side by side are formed, so that the structure is integrated, the mounting is convenient, and the lamination bins 22 can be used for stacking glass sheets at the same time, so that the working efficiency is high. In this embodiment, one lamination stack 22 includes a mounting plate 221 and three pairs of limiting plates 222 to form three lamination stacks 22. A feed port is formed in the top of the lamination chamber 22 to facilitate the glass sheets to slide downwardly from the lamination port into the lamination chamber 22. The mounting plate 221 faces the inner wall of the lamination bin 22, and/or the inner wall of one limiting plate 222 faces the other limiting plate 222 is provided with a plurality of ribs 224 extending along the up-down direction, and the contact between the glass sheet and the wall surface is reduced through the ribs 224, so that breakage is prevented. It is easy to think that a plurality of mounting plates 221 and a plurality of pairs of limiting plates 222 may be adopted, so that a pair of limiting plates 222 are correspondingly mounted on one mounting plate 221, so as to form the lamination cabin 22 around the mounting plate 221, and in this way, the lamination cabin 22 is flexibly discharged, but the structure is complex and the mounting is complicated.

The two limiting plates 222 are mounted on the mounting plate 221, and may be slidably mounted or rotatably mounted. For example, the sliding installation can be realized by using a sliding fit guide rail and a sliding block, wherein the guide rail is installed on the installation plate 221, and the sliding block is installed on the limit plate 222; if the mounting plate 221 is rotatably mounted, a rotating wheel is mounted on the mounting plate, so that the limiting plate 222 is connected with the rotating wheel, and the limiting plate 222 is driven to move by rotation of the rotating wheel. As shown in fig. 4, the first power device 23 is connected to the two limiting plates 222 by providing the first power device 23, and the two limiting plates 222 are moved by driving the two limiting plates 222 to move toward and away from each other. This is because the glass sheets slide down during stacking to easily contact and rub against the inner wall of the lamination magazine 22, which causes displacement, causes irregular stacking, and is also easily broken. Therefore, by making the two limiting plates 222 far away from each other, the contact between the glass sheets and the inner wall of the lamination bin 22 is reduced, and by making the two limiting plates 222 close, the glass sheets are limited from two sides, thereby realizing anthropomorphic operation and orderly stacking the glass sheets.

The first transmission mechanisms 25 are correspondingly connected with the two limiting plates 222 of the lamination bin 22 by adopting the first transmission mechanisms 25, and meanwhile, the first transmission mechanisms 25 are connected with the first power device 23, so that the first power device 23 drives the transmission mechanisms at the same time and drives the two limiting plates 222 to move relatively. On the basis, the adapter plate 24 is adopted, the adapter plate 24 is connected with a plurality of first transmission mechanisms 25, and the first power device 23 is connected with the adapter plate 24 so as to drive the adapter plate 24 to move in the up-down direction. The adapter plate 24 is slidably mounted to the mounting plate 221 on an outer wall surface facing away from the lamination magazine 22. Not only the fixation of the adapter plate 24 is enhanced, so that the installation is more stable; meanwhile, the up-and-down movement of the adapter plate 24 is guided, so that the adapter plate 24 moves along a preset sliding direction, and a good driving effect on the first transmission mechanism 25 is achieved. It will be readily appreciated that depending on the length of the mounting plate 221, one or more sliding mounting locations may be provided on the outer wall surface of the mounting plate 221, thereby enabling a more balanced force to be applied to the adapter plate 24. Taking the length of the mounting plate 221 as an example to meet the requirement of three pairs of limiting plates 222, three sliding mounting positions corresponding to the three lamination bins 22 can be respectively arranged on the outer wall surface of the mounting plate 221, guide rails are respectively arranged, and the adapter plate 24 is correspondingly arranged with the sliding blocks, so that the two limiting plates 222 are uniformly stressed through the first transmission mechanism 25 respectively, and the two limiting plates 222 relatively move.

Since the adapter plate 24 is driven to move up and down to drive the two limiting plates 222 to move relatively, the up and down movement is required to be converted into the relative left and right movement by the transmission mechanism.

As shown in fig. 5, the transmission mechanism comprises a moving plate 251, two pushing plates 252 and an elastic member 253, wherein the moving plate 34 is slidably arranged on the outer wall surface of the mounting plate 221 along the up-down direction and is connected with the first power device 23, and the moving plate 251 is provided with two opposite first surfaces 2521; the two pushing plates 252 are respectively slidably mounted on the outer wall surface of the mounting plate 221 and are correspondingly connected with one ends of the two limiting plates 222 close to the mounting plate 221, and each of the two pushing plates 252 is provided with a second surface 2521 facing the first surface 2521; the first surface 2521 is in sliding fit with the second surface 2521, and the distance between the first surface 2521 and the second surface 2521 gradually increases from bottom to top; the elastic member 253 is connected to the push plates 252 at both ends thereof. The slide rail 363 is attached to the outer wall surface of the mounting plate 221, and the movable plate 251 is connected to the slider, and the movable plate 251 is slidably attached to the mounting plate 221 by sliding engagement of the slider with the slide rail 363. Similarly, the sliding installation of the push plate 252 on the mounting plate 221 is realized by adopting a matching mode of the sliding blocks and the sliding rails 363.

Since the distance between the first surface 2521 and the second surface 2521 is gradually reduced, the two pushing plates 252 are respectively pressed by the moving plate 251 to move in opposite directions, so that the two limiting plates 222 are far away from each other, and since the elastic element 253 is connected between the two pushing plates 252, the sliding of the two pushing plates 252 is buffered, and meanwhile, the elastic element 253 is deformed due to the stress, and the tensile tension is generated. When the first power device 23 drives the moving plate 251 to slide downwards, the distance between the first surface 2521 and the second surface 2521 is gradually increased, the acting force of the moving plate 251 on the two pushing plates 252 is reduced, at this time, the elastic piece 253 generates a shrinkage force opposite to the stretching tension direction due to the reduced acting force, and the elastic piece resets, so that the two pushing plates 252 are pulled to move towards the opposite direction, and the two limiting plates 222 are made to approach each other.

The moving plate 251 and the two pushing plates 252 may be provided in any shape as long as the distance between the first surface 2521 of the moving plate 251 and the second surface 2521 of the pushing plate 252 is gradually increased from bottom to top. If the moving plate 251 is square, the first surface 2521 is a vertical surface, and the second surface 2521 of the push plate 252 is an inclined surface; or vice versa. The first surface 2521 is provided with an inclined surface, and the distance between the two inclined surfaces gradually decreases from bottom to top. The moving plate 251 is formed into a trapezoid, so that the inclination angles between the two inclined planes are different, and trapezoids with different shapes are formed. Preferably isosceles trapezoid, so that the stress is uniform.

Further, the second surface 2521 is provided with a pulley, and the pulley abuts against the first surface 2521. By reducing the contact area between the first surface 2521 and the second surface 2521 by the pulley, the stressed friction is reduced, and a better driving effect is achieved. Of course, instead of using pulleys, a rack and pinion may be used, where the rack is disposed on the first surface 2521, and the pinion is mounted on the second surface 2521, and the pushing of the pushing plate 252 by the moving plate is achieved through the engagement of the rack and pinion.
