[0038] As Figures 1-6As shown, the embodiment provides a laminated frame stacking stack, which comprises a frame 100, a reflow conveying line and a stacking module 200, the reflow conveying line passing through the frame 100. The stacking module 200 comprises a driving assembly 1, two transmission assemblies 2 and two grabbing assemblies 3. The driving assembly 1 is fixed to the frame 100. The two grabbing assemblies 3 are arranged on both sides of the reflow conveying line. The input ends of the two transmission assemblies 2 are connected to the driving assembly 1, and the output ends are correspondingly connected to the two grabbing assemblies 3. The driving assembly 1 can drive the two grabbing assemblies 3 to move along the vertical direction at the same time through the two transmission assemblies 2, so that the two grabbing assemblies 3 are located at the same height for simultaneously grabbing the laminated frame on the reflow conveying line.

[0039] Exemplarily, the conveying direction of the reflow conveying line is X direction, the width direction of the reflow conveying line is Y direction, and the vertical direction is Z direction. The X direction and the Y direction are both horizontal directions, and the Z direction, the X direction and the Y direction are perpendicular to each other. Exemplarily, the frame 100 comprises two side frames 110 arranged along the left-right direction, i.e. the Y direction, and two mounting frames 120 arranged along the front-back direction, i.e. the X direction. The two side frames 110 and the two mounting frames 120 are connected to form a rectangular frame 100. The mounting frame 120 is provided with an opening 121. The two side frames 110 are located on both sides of the reflow conveying line. The reflow conveying line is arranged in the opening 121. The laminated frame flows into and out of the stacking stack through the two openings 121 respectively.

[0040] The frame 100 further comprises a cross beam 130 located at the top and connected to the two side frames 110 at both ends.

[0041] The transmission assembly 2 comprises a transmission shaft 21, a reversing gear 22, a lead screw 23 and a nut 24 matched with the lead screw 23, the transmission shaft 21 is arranged in the horizontal direction, that is, in the Y direction, and the lead screw 23 is arranged in the vertical direction, that is, in the Z direction. The lengths of the transmission shafts 21 of the two transmission assemblies 2 are the same, and the two transmission assemblies 2 are symmetrically connected to the output end of the driving assembly 1 through the transmission shafts 21, that is, symmetrically connected to the two output ends of the double-output speed reducer 12. The transmission shaft 21 and the lead screw 23 are connected through the reversing gear 22, and the nut 24 is connected to the grabbing assembly 3. The structures of the reversing gears 22, the lead screws 23 and the nuts 24 of the two transmission assemblies 2 are the same, so that the two transmission assemblies 2 are symmetrically connected to the output ends of the double-output speed reducer 12. Alternatively, the output end of the double-output speed reducer 12 is an output shaft, the output shaft of the double-output speed reducer 12 and the transmission shaft 21 are connected through a shaft coupling 13, one end of the reversing gear 22 is an output shaft and the other end is an output hole, the output shaft of the reversing gear 22 and the transmission shaft 21 are connected through the shaft coupling 13, and the reversing gear 22 is installed on the side frame 110 through a mounting seat 25 and screws. The top end and the bottom end of the lead screw 23 are rotatably connected to the reversing gear 22 and the frame 100, respectively. The nut 24 connects the lead screw 23 and the grabbing assembly 3, and the rotation of the lead screw 23 causes the grabbing assembly 3 to move along the lead screw 23, that is, in the vertical direction, along with the nut 24.

[0042] Through the cooperation of the structures such as the motor 11, the double-output speed reducer 12, the lead screw 23 and the nut 24, the displacement precision of the grabbing assembly 3 in the vertical direction is improved.

[0043] The grabbing assembly 3 comprises a grabbing frame 31 and a grabbing resisting rod 32, the grabbing frame 31 is connected to the output end of the transmission assembly 2, and the grabbing resisting rods 32 of the two grabbing assemblies 3 face each other, and the grabbing resisting rod 32 is used for grabbing the laminated frame. The grabbing frame 31 is arranged with at least two grabbing resisting rods 32 at the same height position in the horizontal direction, and the grabbing frame 31 is arranged with a plurality of grabbing resisting rods 32 in the vertical direction, and the grabbing resisting rods 32 at the same height are used for grabbing the laminated frame. Exemplarily, the grabbing frame 31 is spliced into a rectangular frame through a plurality of connecting rods, and the grabbing assembly 3 further comprises four strip-shaped plates arranged on the grabbing frame 31 in the horizontal direction, and a plurality of grabbing resisting rods 32 are uniformly connected to the strip-shaped plates in the vertical direction, so that four grabbing resisting rods 32 are arranged at the same height position on each grabbing frame 31. The four grabbing resisting rods 32 at the same height are taken as a group, and a plurality of groups of grabbing resisting rods 32 are arranged in the vertical direction. A group of grabbing resisting rods 32 at the same height simultaneously supports the laminated frame, thereby ensuring the stability of the laminated frame and preventing the laminated frame from being skewed. A plurality of groups of grabbing resisting rods 32 are arranged in the vertical direction, which can correspond to a plurality of laminated frames stacked, thereby increasing the number of laminated frames stacked.

[0044] In one embodiment, the return conveying line comprises at least two conveying belts, and a gap is provided between two adjacent conveying belts; the driving assembly 1 drives the grabbing assembly 3 through the transmission assembly 2, so as to drive the grabbing support 32 to move in the vertical direction; the laminated frame is transported between the gaps between the adjacent grabbing supports 32, i.e., on the conveying belt between two grabbing supports 32, and the laminated frame can be transported to be located on the grabbing support 32 and the conveying belt at the same time; the grabbing support 32 can be moved upward to be located above the conveying belt, so as to make the laminated frame leave the conveying belt in the vertical direction, and only the grabbing support 32 is used to support the laminated frame. Wherein, the length of the laminated frame in the X direction is greater than the length of the conveying belt in the X direction, and is not less than the interval of the two grabbing supports 32, so that the laminated frame can be located on the two grabbing supports 32 at the same time. For example, the conveying belt comprises a driving device, a belt and two transmission rollers, the belt is wound around the two transmission rollers, the driving device drives the rollers to rotate, so as to drive the belt to move, the laminated frame is placed on the belt, and the conveying is realized by moving with the belt. For reference, the prior art is not repeated here.

[0045] In the initial state, the grabbing supports 32 of the two grabbing assemblies 3 are located in the gap between the two conveying belts, i.e., the top height of the grabbing support 32 and the conveying surface height of the conveying belt are the same or approximately the same. The laminated frame is conveyed along with the return conveying line, and when it reaches the preset position, i.e., is located on the grabbing support 32 and the conveying belt at the same time, the driving assembly 1 drives the grabbing assembly 3 through the transmission assembly 2, so as to move the grabbing support 32 upward, the grabbing support 32 supports the laminated frame, the laminated frame is separated from the return conveying line, and the laminated frame is stacked on a group of grabbing supports 32 at the same height. Alternatively, when the driving assembly 1 drives the grabbing support 32 to move upward, the next group of grabbing supports 32 is located between the conveying belts and is in butt joint with the conveying belts, so that the stacking of the next laminated frame can be directly performed.

[0046] When it is needed to take out the laminated frame from the stacking, the driving assembly 1 drives the grabbing support 32 to move downward, so that the grabbing support 32 is located in the initial position, i.e., the grabbing supports 32 of the two grabbing assemblies 3 are in butt joint with the conveying belts, and the laminated frame is located on the grabbing support 32 and the conveying belt at the same time, the top height of the grabbing support 32 and the conveying surface height of the conveying belt are the same or approximately the same, then the driving assembly 1 drives the grabbing support 32 to be lower than the height of the conveying surface of the conveying belt, so that the laminated frame is only located on the return conveying line and is conveyed along with the return conveying line, and the laminated frame is realized to flow out of the stacking.

[0047] The return conveying line is formed by splicing a plurality of conveying belts, the length of each conveying belt is shortened, and the assembly and manufacturing are facilitated. The grabbing support 32 in the form of a rod reduces the gap required to be provided between the adjacent conveying belts, and reduces the influence of the return conveying line formed by the plurality of conveying belts on the transportation of the laminated frame.

[0048] In another embodiment, the width of the laminated frame is greater than the width of the reflow conveying line, so that the two sides of the laminated frame correspond to the outside of the reflow conveying line; the reflow conveying line is located between the grabbing abutting rods 32 of the two grabbing assemblies 3, and the grabbing abutting rods 32 of the two grabbing assemblies 3 are used to support the two sides of the laminated frame.

[0049] In the initial state, the grabbing abutting rods 32 of the two grabbing assemblies 3 are in abutment with the conveying belt, and the top height of the grabbing abutting rods 32 is the same as or approximately the same as the conveying surface height of the conveying belt. The laminated frame is conveyed along with the reflow conveying line, and when it reaches the preset position, it is located between the grabbing abutting rods 32 and the conveying belt, and the middle position of the laminated frame is located on the reflow conveying line, and the two sides correspond to the grabbing abutting rods 32 of the two grabbing assemblies 3. The driving assembly 1 drives the grabbing assembly 3 through the transmission assembly 2 to move the grabbing abutting rods 32 upward, so that the grabbing abutting rods 32 support the laminated frame and separate the laminated frame from the reflow conveying line, and the laminated frame is stacked on a group of grabbing abutting rods 32 at the same height. Alternatively, when the driving assembly 1 drives the grabbing abutting rods 32 to move upward, the next group of grabbing abutting rods 32 is located between the conveying belt and in abutment with the conveying belt, so that the stacking of the next laminated frame can be directly performed. When it is necessary to take out the laminated frame from the stacking stack, the driving assembly 1 drives the grabbing abutting rods 32 to move downward, so that the grabbing abutting rods 32 are located at the initial position, i.e., the grabbing abutting rods 32 of the two grabbing assemblies 3 are in abutment with the conveying belt, and the laminated frame is located between the grabbing abutting rods 32 and the conveying belt, and the top height of the grabbing abutting rods 32 is the same as or approximately the same as the conveying surface height of the conveying belt. Then, the driving assembly 1 drives the grabbing abutting rods 32 to be lower than the height of the conveying surface of the conveying belt, so that the laminated frame is located only on the reflow conveying line and is conveyed along with the reflow conveying line, and the laminated frame flows out of the stacking stack.

[0050] The end of the grabbing abutting rod 32 is provided with a limiting circular table 33, and the generatrix of the limiting circular table 33 faces the reflow conveying line, i.e., the small end of the limiting circular table 33 faces the reflow conveying line, and the large end faces the grabbing frame 31. The distance between the limiting circular tables 33 on the grabbing abutting rods 32 at the same height of the two grabbing assemblies 3 is greater than the width of the laminated frame in the horizontal direction and perpendicular to the conveying direction of the reflow conveying line, i.e., the distance between the limiting circular tables 33 on the grabbing abutting rods 32 at the same height of the two grabbing assemblies 3 is greater than the width of the laminated frame in the Y direction. The side surface of the limiting circular table 33 is an inclined surface, which has a guiding effect. When the laminated frame deviates and is located on the inclined surface of the limiting circular table 33, it slides downward under the action of gravity and the guiding effect of the inclined surface, and then falls onto the grabbing abutting rod 32.

[0051] The laminated frame stacking stack further comprises two guide assemblies 4 corresponding to the two grabbing assemblies 3 for guiding the two grabbing assemblies 3 in the vertical direction, improving the moving accuracy of the grabbing assembly 3 in the vertical direction. The guide assembly 4 comprises a guide rail 41 and a sliding block 42 matched with the guide rail 41, the guide rail 41 is fixed to the side frame 110 of the frame 100, and the sliding block 42 is fixed to the grabbing assembly 3. The end of the guide rail 41 is provided with a stop block 43, such as the upper and lower ends, to prevent the grabbing assembly 3 from slipping off the guide rail 41. Optionally, the grabbing frame 31 of the grabbing assembly 3 is slidably connected to the frame 100 through the two guide assemblies 4, and the two guide assemblies 4 are symmetrically arranged along the lead screw 23. Optionally, three sliding blocks 42 are arranged on the guide rail 41 to improve the stability of operation.

[0052] In the laminating work of the double-glass assembly, when the output speed of the laminated frame from the laminator is greater than the input speed, the laminated frame is stacked to reduce the probability of affecting the laminating of the laminated frame accumulated on the reflow conveying line.

[0053] Driven by a driving assembly 1, i.e. a motor 11, the double-output speed reducer and the two transmission assemblies 2 connected to the output end of the double-output speed reducer are driven to synchronously grab and lift the laminated frame on the reflow conveying line, thereby stacking the laminated frame on the reflow conveying line, reducing the height difference on both sides of the laminated frame during stacking, and further reducing the risk of position deviation of the laminated frame during transportation.

[0054] Obviously, the above embodiments of the present application are only examples for clearly illustrating the present application, and are not intended to limit the embodiments of the present application. For those skilled in the art, other different forms of changes or modifications can be made on the basis of the above description.
