Description

Technical Field

[0001] The utility model belongs to the field of glue spraying machines, and more specifically relates to a glue spraying machine for assembling screens. Background Art

[0002] Glue spraying machine is an automated device specially used for spraying glue on specific parts of display screens. This equipment is widely used in the electronics manufacturing industry, especially in the production process of liquid crystal display (LCD), organic light emitting diode (OLED) and other display screens. The main function of glue spraying machine is to spray glue evenly onto the surface of the material to be bonded to achieve the function of fixing and bonding, thereby ensuring the reliability of the product.

[0003] However, when the existing glue spraying machine is used, different tools and jigs are required for different products, so as to ensure that the glue sprayed on the product is sufficiently uniform and accurately positioned, which increases the cost of the tools and jigs. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a glue spraying machine for assembling screens, which has the advantage of convenient product positioning.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A glue spraying machine for assembling screens comprises a conveyor belt, the glue spraying machine is installed above the conveyor belt, frames are symmetrically provided on the two outer side walls of the glue spraying machine, the frames extend into the interior of the glue spraying machine, a first positioning mechanism for positioning the product is installed in the frames, and a second positioning mechanism for positioning the product is installed on the inner side wall of the glue spraying machine.

[0007] The advantages of this solution are at least as follows: the product is placed on the conveyor belt, which transports the product to the glue sprayer. The second positioning mechanism is first started to prevent the product from moving forward, and then the conveyor belt stops conveying forward. The first positioning mechanism in the frame is then started to fix the product, and then the glue sprayer is started to spray glue on the product. After the product is sprayed with glue, the restrictions on the product by the first positioning mechanism and the second positioning mechanism are released, and then the conveyor belt is started to transport the glue-sprayed product to the designated position.

[0008] The utility model is further configured as follows: the first positioning mechanism comprises a base mounted on the frame, two mounting plates are mounted in the middle of the base, screw rods are rotatably mounted on the two mounting plates, one end of the screw rod passes through the mounting plate, and a motor is mounted on the end of the screw rod;

[0009] A moving block is threadedly connected to the screw rod, a connecting plate is fixedly installed on the moving block, a positioning assembly is installed above the connecting plate, two guide rails are installed on the base, two sliders are installed below the connecting plate, and the sliders are slidably installed on the guide rails.

[0010] The utility model is further configured as follows: the positioning assembly comprises a positioning frame installed on the connecting plate, a first positioning plate installed at one end of the positioning frame, and a plurality of blocking columns installed below the first positioning plate.

[0011] The utility model is further configured as follows: the second positioning mechanism includes a first cylinder installed on the inner side wall of the glue spraying machine, a cylinder fixing plate is installed on the output end of the first cylinder, and also includes a second cylinder installed on the cylinder fixing plate, a second positioning plate is fixed on the output end of the second cylinder, and a plurality of blocking columns are provided below the second positioning plate.

[0012] The utility model is further configured as follows: a counting device is installed on the side wall of the first positioning mechanism, and the counting device comprises a photoelectric sensor installed on the side wall of the base and a counting sheet installed on the side wall of the positioning frame.

[0013] The utility model is further configured as follows: a protection plate is installed on the outer wall of the frame.

[0014] The utility model is further configured as follows: the blocking column is rotatably mounted below the first positioning plate and the second positioning plate.

[0015] The utility model is further configured as follows: a circle of silicone sheet is adhered to the outer surface of the blocking column.

[0016] In summary, the utility model has at least the following advantages:

[0017] 1. By setting the first positioning mechanism and the second positioning mechanism, the product is placed on the conveyor belt, and the conveyor belt transports the product to the glue spraying machine. The second positioning mechanism is first started to prevent the product from moving forward, and then the conveyor belt stops conveying forward, and then the first positioning mechanism in the frame is started to fix the product, and then the glue spraying machine is started to spray glue on the product. After the product is sprayed with glue, the restrictions on the product by the first positioning mechanism and the second positioning mechanism are released, and then the conveyor belt is started to transport the glue-sprayed product to the designated position;

[0018] 2. The blocking column is rotatably installed under the first positioning plate and the second positioning plate and a circle of silicone sheet is adhered to the outer surface of the blocking column, so as to facilitate better positioning of the product. At the same time, the silicone sheet also avoids the phenomenon that the conveyor belt stops conveying, but the product still moves forward, thereby causing friction between the product and the blocking column to cause the product with poor appearance. The first positioning mechanism in the frame is prevented from falling into dust by setting a protective plate;

[0019] 3. By setting a counting device, during the movement of the first positioning mechanism, the counting piece installed on the side wall of the positioning frame will move along with it, thereby moving out of the range of the photoelectric sensor. The number of times it moves out can record how many products have been positioned, and thus how many products have been sprayed with glue, which is convenient for recording the number of products.
