However, the diffuser plate needs to be picked up and positioned before the robot grabs it, and the diffuser plate is relatively soft and thin, similar to a cardboard object, so the general positioning structure is not suitable for the diffuser plate. In the past, the diffuser plate was taken out and installed in the television manually, so positioning was not required, because the workers could correct the position and angle of the diffuser plate at any time during the assembly process. However, in order to improve efficiency and reduce costs, the assembly of televisions now needs to be realized through an assembly line, so mechanical equipment needs to be used to grab and position the stacked diffusers during the assembly process, so the present application designs a diffuser plate positioning assembly machine to solve the above problems.

[0029] As those skilled in the art can fully understand, the features of the different embodiments of the present disclosure can be coupled or combined with each other in part or in whole, and can cooperate with each other in various ways and be driven technically. The embodiments of the present disclosure can be performed independently of each other, or can be performed together in a mutually dependent relationship.

[0030] Reference Figures 1 to 5 The utility model discloses a diffusion plate positioning and assembly machine, including a frame 1, which is a square frame welded by iron pipes, and a stacking platform 2 and a positioning platform 3 are arranged on the frame 1, and the stacking platform 2 and the positioning platform 3 are both square platforms and are adjacently arranged. The suction cup moving mechanism and the suction cup grabbing mechanism are located above the stacking platform 2 and the positioning platform 3. The diffusion plates are stacked into a pile and can be placed on the stacking platform 2 manually. The suction cup moving mechanism and the suction cup grabbing mechanism driven by the suction cup moving mechanism grab the diffusion plates from the stacking platform 2 to the positioning platform 3. Of course, the grabbing action of the present application only requires translation and lifting, so the suction cup moving mechanism includes a suction cup translation mechanism and a suction cup lifting mechanism, and the suction cup grabbing mechanism includes a suction cup frame 5, and a suction cup assembly 6 that can absorb the diffusion plate is provided on the suction cup frame 5. There are a total of sixteen suction cup assemblies 6 in the application, which are arranged in four parallel rows, so as to achieve uniform adsorption force, so that the rapid movement of the suction cup frame 5 after grabbing will not cause a large bending of the diffusion plate.

[0031] like Figure 4 As shown, the suction cup translation mechanism includes a translation linear motor 7 relatively arranged on the frame 1 and a translation frame 8 fixed to the translation linear motor 7. The translation linear motor 7 drives the translation frame 8 to move from the stacking table 2 to the top of the positioning table 3 or return. The suction cup lifting mechanism is installed on the translation frame 8. The suction cup lifting mechanism includes a lifting linear motor 9 fixed on the translation frame 8 and a lifting frame 10 connected to the lifting linear motor 9. The suction cup frame 5 is fixed to the lifting frame 10. When the translation frame 8 moves to the top of the positioning table 3, the lifting linear motor 9 drives the lifting frame 10 and the suction cup frame 5 to descend to the working position, thereby adsorbing the diffusion plate through the suction cup of the suction cup assembly 6.

[0032] As shown in the figure, the suction cup frame 5 includes two oppositely arranged sliding plates 11, a longitudinal rod 12 and two oppositely arranged transverse connecting plates 13. The longitudinal rod 12 is connected to the transverse connecting plates 13 to form a frame. The sliding plate 11 is connected to the frame through a longitudinal moving mechanism. The suction cup assembly 6 is arranged on the frame and the sliding plate 11. The sliding plate 11 is provided to better adapt to diffusers of different lengths. If the diffuser plate is relatively short, the sliding plate 11 can be relatively moved by the longitudinal moving mechanism, so as to move to a position where the edge of the diffuser plate can be absorbed. In the above structure, the longitudinal rod 12 is preferably made of aluminum profile, which is relatively light and easy to purchase. As a further structure, a lifting and mounting plate 14 is provided on the transverse connecting plate 13, and the sliding plate 11 is installed on the lifting and mounting plate 14 by a secondary lifting mechanism. Because the diffuser plate is relatively soft and the surface may be uneven, the sixteen suction cup assemblies 6 are divided into two times to contact the diffuser plate. The eight suction cup assemblies 6 in the middle are directly fixed to the frame. These eight suction cup assemblies 6 are directly in contact with the diffuser plate by the suction cup lifting mechanism, so as to absorb the middle position of the diffuser plate, and then the eight suction cup assemblies 6 relatively arranged on the outside and installed on the sliding plate 11 are driven by the secondary lifting mechanism to descend and absorb and fix the edges on both sides of the diffuser plate. Not only is the force on the diffuser plate uniform, but also the problem of wrinkling of the diffuser plate caused by inequality is avoided.

[0033] The longitudinal moving mechanism uses a motor 15 installed on the cross-connecting plate 13 to drive the transmission screw to cooperate with the lifting mounting plate 14 threadedly to drive the lifting mounting plate 14 to move, thereby driving the sliding plate 11 to move, and the secondary lifting mechanism uses a cylinder 16 installed on the lifting mounting plate 14 to drive the sliding plate 11 to rise and fall. Of course, there is a linear guide assembly connecting the sliding plate 11 and the lifting mounting plate 14.

[0034] It also includes a plurality of positioning seats 17, which are arranged around the stacking table 2 through a linear guide assembly so that they can be moved and adjusted. When adjusted into place, the positioning seats 17 are fixed to the frame 1 through locking screws. The frame 1 is provided with a plurality of screw holes at different distances, so that the positioning seats 17 can be locked at different positions to adapt to diffusion plates of different specifications. The positioning seats 17 of the present application have eight groups, which are surrounded by a square. The diffusion plates are stacked into a pile, and each side of the diffusion plate pile is in contact with two positioning seats 17, thereby preventing the diffusion plates from slipping or tilting, and playing a role of pre-positioning.

[0035] In the above, the translation linear motor 7, the lifting linear motor 9, the suction cup assembly 6, the motor 15, the cylinder 16 and the linear guide assembly are all related mature products purchased from outside, so the specific structure and installation are not described in detail.

[0036] like Figure 2 and 3As shown, the positioning platform 3 in the present application is a square platform formed by welding square steel pipes, and the positioning platform 3 is provided with a transverse flip frame 18 hinged with the positioning platform 3 and a transverse flip driving unit 19 for driving the transverse flip frame 18 to flip, and the transverse flip frame 18 is provided with a longitudinal flip frame 20 hinged with the transverse flip frame 18 and a longitudinal flip driving unit 21 for driving the longitudinal flip frame 20 to flip. Through the above structure, the transverse flip frame 18 and the longitudinal flip frame 20 can be flipped in a predetermined direction respectively, and the transverse flip frame 18 thus forms an inclined state with one side higher and the other side lower, and the longitudinal flip frame 20 also forms an inclined state with one side higher and the other side lower relative to the transverse flip frame 18, and the longitudinal flip frame 20 forms a synthetic spatial inclined state relative to the ground. In the present application, the transverse flip frame 18 and the longitudinal flip frame The flipping direction of 20 is vertical in space, and the flipping angles of the above two can be the same or different. The longitudinal flipping frame 20 is provided with a positioning plate 22, a transverse positioning structure and a longitudinal positioning structure, so that the diffuser placed on the positioning plate 22 can utilize its own gravity to slide on the positioning plate 22 and be positioned against the transverse positioning structure and the longitudinal positioning structure. Of course, the diffusion plate slides along the inclination direction of the longitudinal flipping frame 20, and the above sliding direction can actually be regarded as a synthesis of two sliding directions perpendicular to each other in space, and the transverse positioning structure and the longitudinal positioning structure are respectively located in the above two sliding directions. The diffuser is a square thin plate, so after the diffuser slides, it can be respectively offset against the transverse positioning structure and the longitudinal positioning structure, thereby realizing the positioning of the two sides of the diffuser, thereby realizing the positioning of the diffuser.

[0037] The above-mentioned sliding positioning method utilizes the gravity of the diffuser plate itself, and can be achieved by adjusting the flipping angles of the transverse flip frame 18 and the longitudinal flip frame 20. The size of the contact force between the edge of the diffuser plate and the transverse positioning structure and the longitudinal positioning structure, coupled with the diffuser plate sliding in contact with the positioning plate 22, will not cause bending and deformation of the diffuser plate through the above-mentioned positioning method, and the structure is simple.

[0038] As shown in the figure, as a further structure of the present application, a plurality of air holes 23 are provided on the positioning plate 22, and the air holes 23 are connected to an air source through an air pipe. The air source may be an air pump. Because the diffusion plate may carry static electricity and thus adsorb tightly to the positioning plate 22, air is slightly blown through the air holes 23 to lift the diffusion plate, so that the diffusion plate can slide smoothly and counteract the horizontal positioning structure and the longitudinal positioning structure for positioning. The air pump is a prior art, and thus the specific structure and connection relationship are not described in detail.

[0039] As shown in the figure, the transverse positioning structure and the longitudinal positioning structure both include a plurality of rollers 24 arranged in a row and capable of rotating. The rollers 24 are purchased products, so the specific structure is not described in detail. The rotation of the rollers 24 can better reduce the friction between the diffusion plate and the rollers 24. Of course, the transverse positioning structure and the longitudinal positioning structure can also be square plates or square blocks, etc. As a further structure, the edge of the positioning platform 3 is provided with a transverse positioning groove and a longitudinal positioning groove, and the transverse positioning groove and the longitudinal positioning groove are both provided with connecting screw holes. The wheel axle of the roller 24 is provided with a connecting screw matched with the connecting screw hole, so that the lower edge of the roller 24 can be lower than the upper surface of the positioning plate 22, so when a thin diffuser needs to be positioned, it will not be stuck in the gap between the lower edge of the roller 24 and the upper surface of the positioning plate 22.

[0040] As shown in the figure, the transverse flip drive unit 19 is also a cylinder, and the transverse flip drive unit 19 is connected to the positioning platform 3 through an articulated seat 25. The transverse flip frame 18 is provided with a transverse connecting plate, and the transverse flip drive unit 19 is connected to the transverse connecting plate through a fisheye joint 26. The longitudinal flip drive unit 21 is a cylinder 16, and the transverse flip frame 18 is provided with an L-shaped bracket plate, and the longitudinal flip drive unit 21 is connected to the bracket plate through an articulated seat 25. The longitudinal flip frame 20 is provided with a longitudinal connecting plate, and the longitudinal flip drive unit 21 is connected to the longitudinal connecting plate through a fisheye joint 26. The transverse flip frame 18 is hinged to the positioning platform 3 through a bearing seat; the longitudinal flip frame 20 is hinged to the transverse flip frame 18 through a bearing seat. Through the above structure, we realize the flipping of the transverse flip frame 18 and the longitudinal flip frame 20, and the structure is simple and the cost is low. We can adjust the flipping angle of the transverse flip frame 18 and the longitudinal flip frame 20 by selecting cylinders 16 with different strokes. The bearing seat, cylinder 16, hinge seat 25 and fisheye joint 26 are all related mature products purchased from outside, so the specific structure and installation are not described in detail.

[0041] The above is a detailed introduction to a diffusion plate positioning and assembly machine provided by an embodiment of the utility model. Specific examples are used in this article to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the method of the utility model and its core idea; at the same time, for general technical personnel in this field, according to the idea of ​​the utility model, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the utility model.
