[0009] A rotating shaft is fixedly mounted on the platform and located on one side of the product. The rotating shaft is rotatably mounted on the frame of the equipment.

[0010] A rotation drive mechanism is connected to the rotating shaft to drive the rotating shaft to rotate, thereby causing the stage to rotate 180 degrees around the rotating shaft so that the adhesive application area on the front side faces upward, or the adhesive application area on the back side faces upward.

[0015] As a further improvement to the above technical solution:

[0016] The platform is equipped with a suction cup and also includes a positioning block fixedly installed on the platform, which is used to position and place the product.

[0017] The suction cup includes a substrate. One side of the substrate is an adsorption surface with a plurality of adsorption holes evenly distributed thereon. The other side of the substrate is provided with a plurality of interconnected grooves. The adsorption holes and the grooves are in communication. The substrate is fixedly installed on the stage and a sealed cavity is formed between the grooves and the stage. The sealed cavity is connected to a vacuum generating device. The positioning block is detachably installed on the adsorption surface.

[0018] The substrate is made of plastic.

[0019] The plane located in the center between the front and the back is the center plane of the product. When the front or back of the product is facing up, the pivot is located on the center plane.

[0020] The moving mechanism includes a first linear drive mechanism, and the drying section is a tubular structure that matches the shape of the adhesive application area. The drying section is fixedly installed on the moving end of the first linear drive mechanism, and the first linear drive mechanism drives the drying section to move in the horizontal direction.

[0021] The adhesive application area includes a first linear adhesive application area and a second linear adhesive application area that are perpendicular to each other.

[0022] The drying device further includes a hot air blower, and the drying section includes a first drying pipe, a second drying pipe and a third drying pipe connected to the hot air blower. The first drying pipe corresponds to the first linear adhesive coating area on the front side, the third drying pipe corresponds to the first linear adhesive coating area on the back side, and the second drying pipe covers the second linear adhesive coating area before and after flipping.

[0023] The first linear drive mechanism consists of three parts, with the first drying tube, the second drying tube, and the third drying tube respectively fixedly connected to the moving end of the first linear drive mechanism.

[0049] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0050] Example 1:

[0051] like Figures 1-7 As shown, the automatic double-sided dispensing equipment for screen display panels in this embodiment includes an automatic flipping device 3, an automatic transfer device 1, and an automatic dispensing valve 2.

[0052] The automatic flipping device 3 includes a platform 33, a rotating shaft 32, and a rotation drive mechanism 31.

[0053] The stage 33 is used to fix and place the product 7, which is a screen display panel. The glue application areas on the front and back surfaces of the product 7 are located on the same surface of the product 7, and the glue application areas are located on the outer edge of the stage 33.

[0054] The rotating shaft 32 is fixedly mounted on the platform 33 and located on one side of the product 7. The rotating shaft 32 is rotatably mounted on the frame of the equipment.

[0055] The rotation drive mechanism 31 is connected to the rotating shaft 32 for driving the rotating shaft 32 to rotate, thereby causing the stage 33 to rotate 180 degrees around the rotating shaft 32, so that the adhesive application area on the front side faces upward, or the adhesive application area on the back side faces upward.

[0056] Automatic dispensing valve 2 is installed on the moving end of automatic transfer device 1;

[0057] A drying apparatus, including a drying section and a moving mechanism for driving the drying section to move;

[0058] During dispensing, the automatic transfer device 1 drives the automatic dispensing valve 2 to move above the dispensing area; during drying, the moving mechanism drives the drying unit to move above the upward-facing dispensing area; when the stage 33 is flipped, the automatic dispensing valve 2 and the drying unit move outside the flipping area of ​​the stage 33.

[0059] The adhesive application area is located at the edge of the stage 33, ensuring that when the product 7 is placed on the stage 33, both the front and back adhesive application areas are exposed to the outside. The adhesive application areas on the front and back surfaces of the product 7 are located on the same surface of the product 7, that is, when the product 7 is flipped around the pivot 32, the position and shape of the adhesive application area when the front adhesive application area is facing up and the back adhesive application area is facing up are mirror symmetrical about the pivot 32. The rotation drive mechanism 31 can be a motor, and the output end of the motor is connected to the pivot 32 for transmission.

[0060] When using the automatic double-sided adhesive dispensing equipment for screen display panels in this embodiment:

[0061] First, the operator places and secures product 7 on the platform 33, with the front of product 7 facing up.

[0062] After the equipment is started, the automatic transfer device 1 drives the automatic dispensing valve 2 to apply glue to the glue application area along the set route;

[0063] After the glue is applied, the moving mechanism drives the drying unit to move above the glued area on the front side to dry the glue. After drying, the moving mechanism drives the drying unit to move away from the product 7.

[0064] The rotation drive mechanism 31 is activated, driving the stage 33 to rotate 180 degrees, so that the reverse side of product 7 faces upward.

[0065] Automatic transfer device 1 drives automatic dispensing valve 2 to apply glue to the glue application area along a set route;

[0066] After the glue is applied, the moving mechanism drives the drying unit to move above the glued area on the reverse side to dry the glue.

[0067] After the adhesive has been applied and cured on both sides, the operator removes product 7 from the stage 33.

[0068] By setting a flip-up platform 33 and a movable drying device at a single operating station, and automatically driving the automatic dispensing valve 2 through the automatic transfer device 1 to automatically dispense glue, the three automatic units work together to apply glue to the front or back of the coating area and then dry and cure it immediately. Only the operator needs to load and unload the materials, which reduces labor intensity, improves production efficiency and dispensing quality, and enables batch dispensing of screen display panels by a single person.

[0069] Furthermore, such as Figures 4-6 As shown, the stage 33 is equipped with a suction cup 331 and also includes a positioning block 332 fixedly installed on the stage 33. The positioning block 332 is used to position and place the product 7.

[0070] Specifically, product 7 has a rectangular plate structure, and there are two positioning blocks 332 installed at right angles. The right angles of the blocks are in contact with one right angle of product 7, so that the glue application area is located on the outer edge of the stage 33.

[0071] The supporting surface of the product 7 and the stage 33 is a smooth plane, and the suction cup 331 is used to fix the product 7 conveniently and quickly. The suction cup 331 can be a standard part or a non-standard design.

[0072] Before the operator removes product 7 from the stage 33, the drive mechanism 31 needs to be rotated to flip product 7 so that its face is facing up, and then the operator removes product 7 from the stage 33.

[0073] In another embodiment, the suction cup 331 is a non-standard customized structure, wherein, as shown in... Figure 6 , Figure 8 As shown, the suction cup 331 includes a substrate 3311. One side of the substrate 3311 is an adsorption surface with a plurality of adsorption holes 3312 evenly distributed thereon. The other side of the substrate 3311 is provided with a plurality of interconnected grooves 3313. The adsorption holes 3312 and the grooves 3313 are in communication. The substrate 3311 is fixedly mounted on the stage 33 and a sealed cavity is formed between the grooves 3313 and the stage 33. The sealed cavity is connected to a vacuum generating device. The positioning block 332 is detachably mounted on the adsorption surface.

[0074] The substrate 3311 and the positioning block 332 are made of plastic to avoid scratching the product 7. Specifically, the material is polyoxymethylene (POM). The adsorption surface is attached to the surface of the product 7. When the vacuum generator is started, it draws a vacuum into the sealed cavity, generating suction at the adsorption hole 3312 to adsorb the product 7 onto the adsorption surface.

[0075] The suction cup 331 is designed as an integral plate. The suction surface of the suction cup 331 can be detachably fitted with the positioning block 332. When the specifications of the product 7 change, it is convenient to adjust the position of the positioning block 332 so that the glue application area of ​​each product 7 is located on the outer edge of the stage 33.

[0076] Example 2:

[0077] Based on the above embodiments, in the screen display panel double-sided automatic dispensing equipment of this embodiment, for product 7, the plane located in the middle between the front and back sides is the center plane of product 7. When the front or back side of product 7 is facing up, the rotating shaft 32 is located on the center plane.

[0078] like Figure 6 As shown, the moving mechanism includes a first linear drive mechanism 6, and the drying section is a tubular structure that matches the shape of the adhesive application area. The drying section is fixedly installed on the moving end of the first linear drive mechanism 6, and the first linear drive mechanism 6 drives the drying section to move in the horizontal direction.

[0079] The position of the rotating shaft 32 relative to the product 7 is set at the center surface of the product 7, so that the height of the glue application area is consistent regardless of whether the surface of the product 7 above is front or back. This simplifies the structure of the moving mechanism, allowing only the horizontal position adjustment of the drying section to be achieved, thus reducing equipment costs.

[0080] The drying method can be hot air drying.

[0081] Specifically, such as Figure 7 As shown, the adhesive application area includes a first linear adhesive application area 71 and a second linear adhesive application area 72 that are perpendicular to each other. The second linear adhesive application area 72 after being flipped is collinear with the second linear adhesive application area 72 before being flipped.

[0082] The drying device also includes a hot air blower 4. The drying section includes a first drying pipe 51, a second drying pipe 52 and a third drying pipe 53 connected to the hot air blower 4. The first drying pipe 51 corresponds to the first linear adhesive coating area 71 on the front side, the third drying pipe 53 corresponds to the first linear adhesive coating area 71 on the back side, and the second drying pipe 52 covers the second linear adhesive coating area 72 before and after flipping.

[0083] The number of first linear drive mechanisms 6 is three, and the first drying tube 51, the second drying tube 52 and the third drying tube 53 are respectively fixedly connected to the moving end of a first linear drive mechanism 6.

[0084] For the L-shaped drying area on product 7, the drying section is divided into three locations, allowing the drying mechanism to be suitable for drying product 7 in both flipping states simultaneously. The number of first linear drive mechanisms 6 is the same as the number of drying tubes, i.e., three locations. The equipment control program can control whether hot air enters the drying tubes and which drying tube it enters, based on whether drying is required and the location to be dried, through valves.

[0085] After the adhesive is applied to the front side, a first linear drive mechanism 6 drives the first drying tube 51 to move above the first linear adhesive application area 71 on the front side to dry the adhesive; a first linear drive mechanism 6 drives the second drying tube 52 to move above the second linear adhesive application area 72 on the front side to dry the adhesive; after drying, the first drying tube 51 and the second drying tube 52 move away from the product 7.

[0086] After the reverse side is coated with adhesive, a first linear drive mechanism 6 drives the third drying tube 53 to move above the first linear coating area 71 on the reverse side to dry the adhesive; a first linear drive mechanism 6 drives the second drying tube 52 to move above the second linear coating area 72 on the reverse side to dry the adhesive; after drying, the third drying tube 53 and the second drying tube 52 move away from the product 7.

[0087] like Figure 7 As shown, each first linear drive mechanism 6 includes a cylinder, and the first drying tube 51, the second drying tube 52, and the third drying tube 53 are all connected to the piston rod of a cylinder. The horizontal movement of the drying tubes is achieved by cylinder drive. Specifically, the cylinder can be a rodless cylinder, which is matched with the guide rail that slides the drying tubes on the equipment frame.

[0088] Example 3:

[0089] Based on the above embodiments, the automatic transfer device 1 of the double-sided automatic dispensing equipment for screen display panels in this embodiment includes a second linear drive mechanism 11 and a third linear drive mechanism 12 slidably mounted on the frame of the equipment. The moving end of the second linear drive mechanism 11 is connected to the fixed end of the third linear drive mechanism 12 and is used to drive the third linear drive mechanism 12 to move along a first horizontal direction. The moving direction of the moving end of the third linear drive mechanism 12 is a second horizontal direction, which is perpendicular to the first horizontal direction. A fourth linear drive mechanism 13 is installed on the moving end of the third linear drive mechanism 12. The moving direction of the moving end of the fourth linear drive mechanism 13 is vertical and an automatic dispensing valve 2 is installed thereon.

[0090] The first horizontal movement corresponds to the Y-axis in the diagram, the second horizontal movement corresponds to the X-axis, and the vertical movement corresponds to the Z-axis. The equipment's control program uses XYZ three-axis motion to control and change the automatic dispensing position in real time, and controls the amount of adhesive applied through the automatic dispensing valve 2.

[0091] The second linear drive mechanism 11, the third linear drive mechanism 12, and the fourth linear drive mechanism 13 are all servo linear modules.

[0092] Specifically, the third linear drive mechanism 12 is slidably mounted on the frame via two parallel linear guide rails. The two linear guide rails are located on both sides of the automatic flipping device 3, and the manual operation station is located opposite the third linear drive mechanism 12. The three-axis servo drive realizes the automatic movement of the automatic dispensing valve 2 while making the overall structure of the equipment compact and reducing the space occupied.
