Description

Technical Field

[0001] The utility model relates to the technical field of screen demoulding after glue injection, in particular to a screen demoulding device after glue injection. Background Art

[0002] The screen glue injection process is to inject silicone into the gap between the screen and the frame to achieve the purpose of bonding, filling and protection. When the silicone cures naturally, it will gradually lose its viscosity and be fixed in the desired position.

[0003] Due to the strong adhesion between the silicone and the mold, or the unreasonable design of the mold, the screen cannot be smoothly removed from the mold, so a demolding operation is required. The demolding operation usually involves using appropriate tools or equipment, such as a demolding knife or scraper, to gently peel the screen from the mold. This process must be performed carefully to avoid damaging the screen. Therefore, a quick and safe demolding device needs to be proposed. Utility Model Content

[0026] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0027] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] See also Figures 1 to 7 , which is a screen demoulding device after glue injection according to an embodiment of the utility model, includes a lower blowing component 10 and an upper blowing component 20 arranged above the lower blowing component 10; the upper blowing component 20 and the lower blowing component 10 are used to clamp the mold 30 and the screen 40 located on the mold 30.

[0030] The lower air blowing assembly 10 includes a lower support plate 11, positioning pins 12 installed at opposite ends of the top surface of the lower support plate 11, lower air blowing heads 13 installed at opposite ends of the top surface of the lower support plate 11, and lower air blowing speed regulating valves 14 installed at opposite ends of the bottom surface of the lower support plate 11; the lower air blowing speed regulating valves 14 are connected to the lower air blowing heads 13 one by one to control the air flow rate of each lower air blowing head 13. Among them, the lower support plate 11 is used to place the mold 30, and the positioning pins 12 are used to limit the position of the mold 30 to ensure positioning accuracy. Specifically, the lower air blowing head 13 is located directly below the screen 40, and the airflow of the lower air blowing head 13 is used to impact the screen 40, forming an upward force on the screen 40, so that the screen 40 is separated from the mold 30 upward.

[0031] The upper air blowing assembly 20 includes an upper support plate 21 located above the lower support plate 11, a plurality of suction cups 22 installed on the bottom surface of the upper support plate 21, an exhaust valve 23 installed on the top surface of the upper support plate 21, a plurality of upper air blowing speed regulating valves 24 arranged at intervals along the periphery of the top surface of the upper support plate 21, and a movable arm 25 floatingly connected to the top surface of the upper support plate 21. Among them, a plurality of air blowing grooves 210 are arranged at intervals along the periphery of the bottom surface of the upper support plate 21, and the air blowing grooves 210 are connected to the upper air blowing speed regulating valves 24 in a one-to-one correspondence. The air blowing grooves 210 are distributed along the outer side of the periphery of the screen 40, and the air flow of the air blowing grooves 210 is used to impact the mold 30. In simple terms, the air flow of the air blowing grooves 210 blows outside the screen 40, and only impacts the mold 30, but does not impact the screen 40.

[0032] like Figure 5 As shown, in this embodiment, the blowing direction of the blowing slot 210 is inclined, and the angle formed between the blowing direction of the blowing slot 210 and the horizontal direction is 80 degrees, which can effectively impact the mold 30, form a downward force on the mold 30, and let the mold 30 downwardly separate from the screen 40. Compared with the traditional demoulding operation, the utility model saves the demoulding knife or scraper, uses the suction cup 22 to absorb the screen 40, the airflow of the upper blowing slot 210 impacts the mold 30, and the airflow of the lower blowing head 13 impacts the screen 40, quickly separating the screen 40 from the mold 30, eliminating rigid contact, avoiding damage to the screen, and greatly improving the convenience and safety of demoulding.

[0033] In this embodiment, the movable arm 25 includes an arm body 251 slidably connected to the top surface of the upper support plate 21, an arm sleeve 252 slidably connected to the top of the arm body 251, a spring 253 connected between the arm body 251 and the arm sleeve 252, and a pressure sensor 254 connected to the bottom of the arm body 251; the pressure sensor 254 is sandwiched between the bottom of the arm body 251 and the top surface of the upper support plate 21. Among them, the arm sleeve 252 is used to connect to a transmission tool such as a lifting cylinder or a manipulator, which can drive the entire upper blowing assembly 20 to perform lifting and lowering movements. The combination of the spring 253 and the pressure sensor 254 can effectively control the downward pressure of the entire upper blowing assembly 20 to prevent damage to the screen 40.

[0034] The above-mentioned screen demoulding device after glue injection uses a suction cup 22 to absorb the screen 40, the airflow of the upper blowing groove 210 impacts the mold 30, and the airflow of the lower blowing head 13 impacts the screen 40, so that the screen 40 and the mold 30 are quickly separated, eliminating rigid contact, avoiding damage to the screen, and greatly improving the convenience and safety of demoulding.

[0035] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
