Detailed implementation manners

[0024] The following will describe in detail the embodiments of the present invention with reference to the accompanying drawings.

[0025] As Figures 1-6 shown, a process edge automatic glue wiping device includes a cloth roll supply module 1 for leading out a cloth belt and a cloth roll recycling module 2 for collecting the cloth belt.

The wiping press head module 3 includes a fixed substrate 31 and a floating pressure regulating press head 32 installed on the fixed substrate 31. The floating pressure regulating press head 32 is connected with a guiding block 33 for pulling the cloth belt to move, and a vacuum suction head 36 for adsorbing glue is installed on one side of the fixed substrate 31.

[0026] Driven by the cloth roll recycling module 2, the cloth belt moves, so as to lead out the cloth belt from the cloth roll supply module 1. At the same time, the cloth belt passes through the wiping press head module 3 during the movement process, and under the action of the wiping press head module 3, the cloth belt is pulled to perform a glue wiping operation on the process edge of the product.

[0027] The fixed substrate 31 is fixedly connected to the cloth roll supply module 1 by bolts, ensuring that the cloth roll supply module 1 and the wiping head module 3 are always in a relative position. The floating pressure-regulating head 32 can be a cylinder or an oil cylinder structure. Under the action of the floating pressure-regulating head 32, the movement of the guide block 33 is driven, so that the guide block 33 presses on the wiping area of the product. The cloth belt passing through the guide block 33 contacts the wiping area of the product under the guiding action of the guide block 33, realizing the wiping of the wiping area of the product.

[0028] Relative to the guide block 33, the vacuum suction head 36 is located at the front end in the cloth belt conveying direction. The guide block 33 is used to wipe the wiping area of the product, and the vacuum suction head 36 is used to adsorb the printing glue in the product wiping area in advance to ensure the wiping effect of the guide block 33 on the wiping area. The vacuum suction head 36 located at the front end in the cloth belt conveying direction can adsorb the excess printing glue pushed by the guide block 33.

[0029] A slide table 37 for adjusting the spatial position of the vacuum suction head 36 is installed on one side of the fixed substrate 31. The guide block 33 includes a guide body 34 and a wiping block 35 located in the middle of the guide body. The size of the wiping block 35 is set according to actual needs, so that different wiping blocks 35 can meet the rubber wiping requirements of different process edges.

[0030] The cloth roll supply module 1 includes a module base 11 and a cloth belt driven wheel 12 for loading the cloth belt. The cloth belt driven wheel 12 is rotatably connected to the module base 11, and a cloth belt guiding mechanism 13 for guiding the cloth belt conveying direction and a cloth belt tensioning mechanism 14 for tensioning the cloth belt are installed on the module base 11.

[0031] The cloth belt is wound around the cloth belt driven wheel 12, and the cloth belt can be led out under the passive rotation of the cloth belt driven wheel 12. The cloth belt guiding mechanism 13 is composed of several cloth belt guiding wheels. The cloth belt tensioning mechanism 14 is composed of a cloth belt detection sensor and a tensioning block movably connected to the module base 11. The cloth belt passes through each cloth belt guiding wheel in turn during the transmission process, and under the action of several cloth belt guiding wheels, the guiding of the cloth belt is realized. The tensioning block realizes the tensioning of the cloth belt by moving. At the same time, the cloth belt detection sensor is arranged on the transmission path of the cloth belt, and the tensioning condition of the cloth belt is detected by detecting the pressure of the cloth belt on the cloth belt detection sensor.

[0032] A solvent spray head 6 for spraying solvent on the cloth belt is provided between the cloth roll supply module 1 and the wiping head module 3. A constant-resistance solvent squeezing and leveling module 4 for squeezing the excess solvent of the cloth belt is provided at the solvent spray head 6.

The knurled wheel 42 is always at the same horizontal height under the action of the mounting base 41. The height of the pressure regulating wheel 44 is adjustable under the action of the pressure regulating platform 43. The cloth tape is located between the knurled wheel 42 and the pressure regulating wheel 44, so that the knurled wheel 42 and the pressure regulating wheel 44 can squeeze the cloth tape by the downward pressure of the pressure regulating wheel 44.

[0035] The pressure regulating wheel 44 is arranged corresponding to the knurled wheel 42. A lever 45 for controlling the height of the pressure regulating wheel 44 is provided on the pressure regulating platform 43. A constant-torque damper 46 connected to the knurled wheel 42 is mounted on the back of the mounting base 41. The cloth tape with solvent drives the knurled wheel 42 in contact with the cloth tape after being squeezed by the pressure regulating wheel 44. In this process, the solvent on the cloth tape is evenly infiltrated, and the excess solvent is extruded and falls into the solvent recovery tank below. The knurled wheel 42 is connected to the constant-torque damper 46 to ensure the consistency of the cloth tape tension. A screw for locking the height of the pressure regulating wheel 44 is provided on the pressure regulating platform 43, so as to ensure the stability of the distance between the knurled wheel 42 and the pressure regulating wheel 44.
