Description

Technical Field

[0001] This utility model relates to the field of display manufacturing equipment technology, specifically to a deformable suction nozzle mechanism for an automatic spacer strip attaching machine. Background Technology

[0002] The current method for attaching spacers to the four sides of a monitor frame is primarily manual. First, the worker peels the spacer material off the release paper, then attaches the spacer to the corresponding position on the flat or curved surface of the frame. Manual application requires a back-pressing motion. This manual method of attaching spacers has the following drawbacks:

[0003] 1. Manual application can easily result in misaligned spacer strips;

[0004] 2. If the back pressure action is missed during manual application, the spacer strip may become loose and unusable.

[0005] 3. Manual labor is less efficient;

[0006] 4. Stacking occurs after the spacers are attached to the frame;

[0007] 5. Manual application has low accuracy;

[0008] 6. High manpower requirements. Summary of the Invention

[0009] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a deformable suction nozzle mechanism for an automatic spacer strip attaching machine.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] A deformable suction nozzle mechanism for an automatic spacer strip attaching machine includes a suction nozzle body connected to the actuator end of a robotic arm, which moves the suction nozzle body. The suction nozzle body includes a suction nozzle frame with vertical guide rails on both sides. Adjustment blocks are slidably connected to the two vertical guide rails and can be positioned at different positions on the vertical guide rails. A row of suction heads arranged in an arc shape is connected between the adjustment blocks on both sides. Adjacent suction heads are hinged together by side pins. The outer sides of the first and last suction heads are hinged to the corresponding side adjustment blocks by pins. Adjusting the height of the two adjustment blocks changes the curvature of the suction head array.

[0012] Furthermore, a baffle is provided at the bottom of the nozzle body and on the side of the suction head array.

[0013] Furthermore, the robotic arm is a four-axis SCARA robotic arm.

[0014] Furthermore, each of the two sides of the nozzle holder is threaded with a locking screw, which tightens the corresponding adjustment block to achieve the positioning of the adjustment block.

[0015] Furthermore, the top of the nozzle holder is provided with an air suction box, and the top of each suction head is connected to the corresponding air hole on the air suction box through a suction tube. The upper part of the air suction box is connected to a vacuum generator through an air pipe.

[0016] The present invention adopts the above technical solution and has the following beneficial effects:

[0017] 1. This utility model can adjust the curvature of the suction head array through a mechanical linkage structure to adapt to the curvature of the adhesive frame with different application requirements, thereby enhancing versatility. Through the coordinated control of the deformable suction nozzle and the robotic arm, the dynamic adjustment of the suction nozzle shape and the adaptive gripping action can be realized, thereby improving the adhesion accuracy and efficiency.

[0018] 2. A foolproof baffle is designed at the bottom of the nozzle to correct the spacer strip. Attached Figure Description

[0022] Figure 3 This is a schematic diagram of the internal structure of the suction nozzle body. Detailed Implementation

[0023] like Figure 1-3 As shown, the present invention discloses a deformable suction nozzle mechanism for an automatic spacer strip attaching machine, comprising a suction nozzle body 1 connected to the execution end of a robotic arm 2, wherein the robotic arm 2 drives the suction nozzle body 1 to move. The suction nozzle body 1 includes a suction nozzle frame 11, wherein vertical guide rails 12 are respectively provided on both sides of the suction nozzle frame 11, and adjusting blocks 13 are slidably connected to the two vertical guide rails 12 respectively, and the adjusting blocks 13 can be positioned at different positions on the vertical guide rails 12. The two sides of the suction nozzle frame 11 are respectively threaded with locking screws corresponding to the two adjusting blocks 13, and the positioning of the adjusting blocks 13 is achieved by tightening the corresponding adjusting blocks 13 with the locking screws.

[0024] An array of suction heads 3 is connected between the adjusting blocks 13 on both sides. In this embodiment, the array of suction heads 3 is arranged in an arc shape. Two adjacent suction heads 3 are hinged together by a pin on the side. The outer sides of the first and last suction heads 3 are respectively hinged to the adjusting blocks 13 on the corresponding sides by pins. The curvature of the array of suction heads 3 can be changed by adjusting the height position of the two adjusting blocks 13.

[0025] To simplify the structure, the top of the nozzle holder 11 is provided with a suction box 15. The top of each suction head 3 is connected to the corresponding air hole on the suction box 15 through a suction tube. The upper part of the suction box 15 is connected to the vacuum generator through an air pipe.

[0026] A baffle 14 is provided at the bottom of the nozzle body 1 and on the side of the suction head 3 array. When the nozzle picks up the special sheet material spacer, in order to prevent the spacer from deviating, a baffle 14 is added at the bottom of the nozzle body 1 to serve as a spacer correction.

[0027] Among them, the robotic arm 2 is a four-axis SCARA robotic arm, which is mounted on a base 4.

[0028] In this invention, the suction head array 3 adopts a chain-type connection structure. By moving the height position of the two side adjustment blocks 13, the curvature of the suction head array 3 can be adjusted to adapt to the curvature of the adhesive frame with different application requirements, thereby enhancing versatility. Through the coordinated control of the deformable suction nozzle and the robotic arm 2, the dynamic adjustment of the suction nozzle shape and the adaptive gripping action can be realized, thereby improving the adhesion accuracy and efficiency.

[0029] The specific embodiments of this utility model have been described above. However, those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this embodiment without departing from the principle and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
