Description

Technical fields:

[0001] This utility model relates to the field of door and window sealant application technology, specifically to a device for precise adjustment of the position and posture of a sealant applicator head. Background technology:

[0002] The glue applicator head is the core component of a glue applicator. To ensure glue application quality and that the glue nozzle remains in constant contact with the door and window, current technology typically slides the glue applicator head onto a rotating base. The rotating base is primarily for applying glue at corners, and a spring is installed between the glue applicator head and the rotating base. The spring applies pressure to the glue applicator head to ensure continuous glue contact. The specific structure is as follows: Figure 7 As shown, as well as the precision glue application structure for automatic door and window glue application machine (authorization announcement number: CN214487626U) and the palletized fully automatic door and window glue application machine (authorization announcement number: CN219003544U) previously applied for by our company.

[0003] The aforementioned technical solutions improve the quality of sealant application to some extent, but deeper technical problems have been discovered in practical applications. Due to the different door and window models, the tilt angle of the sealant nozzle needs to be adjusted to meet the sealant application requirements of different models. However, after the tilt angle of the sealant nozzle changes, the tip of the nozzle is no longer aligned with the rotation center of the rotating seat. Since the sealant application path is set according to the rotation center, this leads to changes in the applied pre-tightening force. Changes in pre-tightening force directly affect the sealant application finish; a larger pre-tightening force results in more sealant protrusions (i.e., overlapping sealant areas), severely affecting aesthetics. Conversely, a smaller pre-tightening force reduces the number of sealant protrusions (i.e., overlapping sealant areas), but the sealant application quality is affected. Therefore, it is necessary to optimize the structure of the sealant application head to adapt to the sealant application needs of different doors and windows while ensuring sealant application quality.

[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content:

[0005] The purpose of this utility model is to solve the problems existing in the prior art and provide a precise adjustment device for the position and posture of the glue applicator head, which has the advantages of reasonable structural design, precise position and posture adjustment, and good glue application quality.

[0006] This utility model achieves the above objectives by adopting the following technical solutions:

[0007] A precise adjustment device for the position and posture of a glue applicator head includes a rotating base and a glue applicator head. The lower end of the rotating base is provided with a guide rail along its length, and a slide is provided on the guide rail. The glue applicator head is provided at the lower end of the slide. A lead screw is rotatably provided at the lower end of the rotating base. One end of the lead screw is connected to a motor. A lead screw nut is provided on the lead screw, and a lead screw nut seat is provided on the slide. The lead screw nut and the lead screw nut seat are slidably arranged relative to each other, and a spring is connected between the lead screw nut and the lead screw nut seat.

[0008] The nut is provided with multiple guide rods spaced apart, and the corresponding nut seat is provided with guide holes, into which the guide rods are inserted.

[0009] The guide rod is designed as a guide shaft, and a linear bearing is provided on the corresponding guide hole. The guide shaft is mounted on the linear bearing.

[0010] A spring is connected at the center between the nut and the nut seat. Each end of the spring is provided with a spring seat, which is installed on the nut or nut seat by a threaded connection.

[0011] The upper end of the rotating base is provided with a rotating shaft that drives its rotation.

[0012] The lower end of the rotating seat is provided with two guide rails spaced apart along its width direction, and the guide rails are provided with sliders, and the sliders are provided with slide blocks.

[0013] The two ends of the lead screw are rotatably mounted on a rotating seat via bearings.

[0014] The present invention, by adopting the above-described structure, can bring the following beneficial effects:

[0015] By installing a motor, lead screw, lead screw nut, and lead screw nut seat at the lower end of the rotating base, the initial position of the glue dispensing head can be precisely adjusted. That is, when the glue nozzle angle is tilted, the initial position of the glue dispensing head can be adjusted to ensure that the tip of the glue nozzle remains vertically aligned with the center of rotation, ensuring accurate glue dispensing. By designing a guide rod and spring between the lead screw nut and lead screw nut seat, not only is linear motion achieved, but the spring also enables glue pre-tensioning. The combination of these two elements ensures accurate and reliable glue dispensing. Attached image description:

[0024] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0026] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0027] Furthermore, the terms “upper end,” “lower end,” “horizontal,” “longitudinal,” and “vertical” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the location of the indicated technical feature.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "provided with," "set up," and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] like Figure 1-6As shown, the precision adjustment device for the position and posture of the glue applicator head includes a rotating base 1 and a glue applicator head 4. The lower end of the rotating base 1 is provided with a guide rail 2 along its length direction. A slide 3 is provided on the guide rail 2. The glue applicator head 4 is provided at the lower end of the slide 3. A lead screw 5 is rotatably provided at the lower end of the rotating base 1. One end of the lead screw 5 is connected to a motor 6. The motor 6 is connected to the lead screw 5 through a coupling. The motor can be a stepper motor or a servo motor. A lead screw nut 7 is provided on the lead screw 5. A lead screw nut seat 8 is provided on the slide 3. The lead screw nut 7 and the lead screw nut seat 8 are slidably arranged relative to each other, and a spring 9 is connected between the lead screw nut 7 and the lead screw nut seat 8. Compared to the existing pre-tension spring 22 structure, this application achieves precise adjustment of the initial position of the glue applicator head 4 by setting a motor 6, lead screw 5, lead screw nut 7, and lead screw nut seat 8 at the lower end of the rotating base 1. That is, when the glue applicator nozzle 19 is tilted, the initial position of the glue applicator head 4 can be adjusted to ensure that the end of the glue applicator nozzle 19 is still vertically aligned with the rotation axis 23 of the rotating base 1, thus ensuring accurate glue application. By designing a guide rod 10 and a spring 9 between the lead screw nut 7 and the lead screw nut seat 8, not only is linear motion achieved, but the glue pre-tension can still be achieved by relying on the spring 9. The combination of the two can ensure accurate and reliable glue application.

[0030] The nut 7 is provided with a plurality of guide rods 10 spaced apart, and the corresponding nut seat 8 is provided with guide holes 11, into which the guide rods 10 are inserted. By using the guide rods 10 and guide holes 11 in cooperation, not only can linear motion be achieved, but the requirements for relative sliding settings can also be met, providing a basis for the pre-tightening of the spring 9 with glue.

[0031] The guide rod 10 is designed as a guide shaft 12, and a linear bearing 13 is provided on the corresponding guide hole 11. The guide shaft 12 is mounted on the linear bearing 13. Precision guidance is achieved by using the guide shaft 12 and the linear bearing 13 in cooperation.

[0032] A spring 9 is connected at the center between the nut 7 and the nut seat 8. Spring seats 14 are located at both ends of the spring 9, and the spring seats 14 are installed on the nut 7 or the nut seat 8 via threaded connections 15. Existing nut 7 typically achieves linear movement by being threadedly fastened to the nut seat 8. However, this application, through the design of the guide rod 10 and the spring 9, achieves both linear movement and relative movement between the nut seat 8 and the nut 7. Specifically, the nut seat 8 can compress the spring 9 and cause displacement under external force. This feature allows for pre-tightening during glue application, ensuring the glue nozzle remains in contact with the edge of the door or window, and also facilitating finishing operations. Positioning the spring 9 at the center helps ensure even force distribution and simplifies installation.

[0033] The upper end of the rotating seat 1 is provided with a rotating shaft 16 for driving its rotation. The rotating seat 1 is driven to rotate by driving the rotating shaft 16 to rotate, which mainly realizes the application of sealant to the corners of doors and windows and the application of sealant to adjacent edges when turning.

[0034] The lower end of the rotating base 1 is provided with two guide rails 2 spaced apart along its width direction. The guide rails 2 are provided with sliders 17, and the sliders 17 are provided with slide blocks 3. The symmetrical design and the use of guide rails and sliders for sliding provide high precision and stability.

[0035] The two ends of the lead screw 5 are respectively rotatably mounted on the rotating seat 1 via bearings 18.

[0036] The glue dispensing head 4 can be made using existing technology, and multiple glue dispensing nozzles 19 can be set in the glue dispensing head 4 (e.g. Figure 6 As shown, different glue nozzles 19 can be replaced by glue nozzle replacement motor 21, or a single glue nozzle 19 can be set up, but the glue nozzle 19 has a tilt angle adjustment function (the tilt angle of the glue nozzle 19 can be adjusted by tilt angle adjustment motor 20).

[0037] The above-described specific embodiments should not be construed as limiting the scope of protection of this utility model. Any substitutions, improvements, or modifications made to the embodiments of this utility model by those skilled in the art shall be deemed appropriate.

[0038] Within the protection scope of this utility model.

[0039] Any aspects of this utility model not described in detail are known to those skilled in the art.
