[0033] In one embodiment of this utility model, such as Figure 1-7As shown, a glue applicator head structure includes a worktable 1, a mounting base 2, a first drive device 31, a second drive device 32, a first gear 41, a second gear 42, a third gear 43, a rotating shaft 51, a bearing 52, a turntable 6, a glue applicator rod 71, a brush head 72, a glue container 8, and a fixing assembly 9. The mounting base 2 and the fixing assembly 9 are respectively mounted on the worktable 1. The fixing assembly 9 is used to clamp and fix the workpiece. The mounting base 2 is respectively equipped with the first drive device 31 and the second drive device 32. The first gear 41 is mounted on the output end of the first drive device 31, and the second gear 32... The output end of the device is equipped with the rotating shaft 51, the bearing 52 is mounted on the rotating shaft 51, and the second gear 42 is mounted on the outer periphery of the bearing 52; the turntable 6 is mounted on the rotating shaft 51, the glue applicator 71 is rotatably mounted on the turntable 6, one end of the glue applicator 71 is equipped with the brush head 72, and the other end of the glue applicator 71 is equipped with the third gear 43, the second gear 42 meshes with the first gear 41 and the third gear 43 respectively; the glue box 8 is located between the turntable 6 and the fixing assembly 9, and the end of the rotating shaft 51 and the brush head 72 are located inside the glue box 8.In this embodiment, both the first drive device 31 and the second drive device 32 are motors. The mounting base 2 is installed at the rear end of the workbench 1, and the fixing component 9 is installed at the front end of the workbench 1. The mounting base 2 is respectively equipped with the first drive device 31 and the second drive device 32. The second drive device 32 is located above the first drive device 31. The rotating shaft 51 is installed at the output end of the second drive device 32. The rotating shaft 51 is respectively equipped with the bearing 52 and the turntable 6. The front end of the rotating shaft 51 protrudes from the turntable 6. The bearing 52 is located on the rear side of the turntable 6. The second gear 42 is installed on the outer periphery of the bearing 52. The glue applicator 71 is installed... At the turntable 6, the brush head 72 is installed at the front end of the glue-applying rod 71. The brush head 72 is a toothed precision steel plate structure. The third gear is installed at the rear end of the glue-applying rod 71. The front half of the second gear 42 meshes with the third gear 43, and the rear half of the second gear 42 meshes with the first gear 41. The front ends of the brush head 72 and the rotating shaft 51 are both located inside the glue box 8. The glue box contains glue. During operation, the workpiece to be glued is inserted into the front end of the rotating shaft 51 and clamped and fixed by the workpiece clamp. The first driving device 31 drives the first gear 41 at its output end to rotate. The rotation of the first gear 41 drives the second gear 42 to rotate. The rotating shaft 51 does not rotate. Then, the second gear 42 drives the third gear 43 to rotate. The third gear 43 drives the glue-applying rod 71 to rotate, causing the brush head 72 to move in a circular motion along the glue-applying rod 71. This causes the brush head 72 to swing downwards and apply glue. Then, the glue-applying rod 71 continues to rotate, causing the brush head 72 to swing to the outer circumference of the workpiece. Then, the first driving device 31 stops working, and the second driving device 32 drives the rotating shaft 51 at its output end to rotate. At this time, the second gear 42 does not rotate. The rotation of the rotating shaft 51 drives the turntable 6 to rotate. The rotation of the turntable 6 drives the glue-applying rod 71 to move in a circular motion along the center of the turntable 6, thereby causing the brush head 72 to move in a circular motion along the center of the turntable 6. The movement allows the adhesive on the brush head 72 to be evenly applied to the outer periphery of the workpiece. This application utilizes a simple and ingenious linkage structure consisting of a worktable 1, a mounting base 2, a first drive device 31, a second drive device 32, a first gear 41, a second gear 42, a third gear 43, a rotating shaft 51, a bearing 52, a turntable 6, an adhesive applicator 71, a brush head 72, an adhesive box 8, and a fixing component 9. This structure allows for both adhesive application and dispensing, making it convenient, fast, and efficient. Compared to traditional complex rotary adhesive application structures, this structure is simpler and has lower production costs. Furthermore, the brush head 72 uses a toothed precision steel sheet for adhesive application, which avoids uneven adhesive application caused by the stepped surface of the workpiece, thus preventing the workpiece from showing white areas and causing product defects.

[0034] like Figure 3-4 As shown, the front end of the rotating shaft 51 is provided with a mounting boss 511, which has a tapered structure. In this embodiment, the mounting boss 511 is provided at the front end of the rotating shaft 51, and the mounting boss 511 has a tapered structure, which facilitates the insertion and installation of pipe workpieces and prevents jamming during insertion.

[0035] like Figure 1-2 As shown, the system also includes a protective cover 10, which is installed on the workbench 1. The protective cover 10 covers the mounting base 2, the first driving device 31, the second driving device 32, the first gear 41, the second gear 42, the third gear 43, the rotating shaft 51, the bearing 52, the turntable 6, the glue applicator 71, the brush head 72, and the glue container 8. In this embodiment, the glue container 8 is installed on the inner wall of the protective cover 10. The protective cover 10 covers the mounting base 2, the first driving device 31, the second driving device 32, the first gear 41, the second gear 42, the third gear 43, the rotating shaft 51, the bearing 52, the turntable 6, the glue applicator 71, the brush head 72, and the glue container 8. The protective cover 10 provides protection, preventing the internal components from being disturbed by external factors. Furthermore, the front side of the protective cover 10 has a feed inlet to facilitate the placement of workpieces.

[0036] like Figure 2 and Figure 5 As shown, the glue box 8 includes a box body 81, a top cover 82, a glue inlet tube 83, and a glue outlet tube 84; the box body 81 is installed on the inner wall of the protective cover 10, and the box body 81 has a glue-applying cavity 811 and a glue outlet cavity 812. The glue outlet cavity 812 is located on the outer periphery of the glue-applying cavity 811, and the top cover 82 is installed on the top of the box body 81; the glue inlet tube 83 and the glue outlet tube 84 are respectively installed on the workbench 1, the glue inlet tube 83 is connected to the glue-applying cavity 811, and the glue outlet tube 84 is connected to the glue outlet cavity 812. In this embodiment, the top cover 82 has an arc structure and is installed on the top of the box body 81. The front and rear sides of the box body 81 are respectively provided with corresponding clearance areas. The box body 81 and the top cover 82 cover the front end of the rotating shaft 51 and the brush head 72, which can prevent glue from splashing during the brush head 72 swinging and applying glue. During operation, glue is delivered to the glue application chamber 811 through the glue inlet pipe 83. The brush head 72 swings to the glue application chamber 811 to apply glue, and a small part of the glue that is thrown out is caught by the top cover 82 and the box body 81, so that it flows to the glue discharge chamber 812, thereby discharging and recycling the glue, which is convenient and quick. Specifically, when the glue in the glue application chamber 811 is full, it will overflow into the glue discharge chamber 812, so that the glue can achieve self-circulation and flow, making the glue less likely to solidify.

[0037] like Figure 5-6 As shown, the adhesive application chamber 811 is equipped with an adhesive application plate 813, and the brush head 72 can abut against the adhesive application plate 813. In this embodiment, the adhesive inlet of the adhesive inlet tube 83 is located below the adhesive application plate 813. During operation, the brush head 72 swings to abut against the adhesive application plate 813. With the support of the adhesive application plate 813, the brush head 72 can apply adhesive more conveniently and quickly.

[0038] like Figure 2 and Figure 7 As shown, the fixing assembly 9 includes a fixing plate 91, a fixing seat 92, a third driving part 93, and a fourth driving part 94. The fixing plate 91 is mounted on the worktable 1. The third driving part 93 is mounted on the top surface of the fixing plate 91. The fixing seat 92 is mounted on the output end of the third driving part 93, and the fourth driving part 94 is mounted on the fixing seat 92. In this embodiment, the third driving part 93 is a telescopic cylinder, and the fourth driving part 94 is a gripper cylinder. During operation, after the workpiece is placed on the fourth driving part 94, the fourth driving part 94 clamps and fixes the workpiece. Then, the third driving part 93 on the top surface of the fixing plate 91 drives the fixing seat 92 to move towards the rotating shaft 51, so that the workpiece clamped by the fourth driving part 94 is inserted into the mounting boss 511 of the rotating shaft 51. After the glue application is completed, it returns to its original position, which is convenient and quick.

[0039] like Figure 7 As shown, the fixing assembly 9 further includes a movable seat 95, a buffer rod 96, and an elastic element 97; the top surface of the fixing seat 92 is provided with a slide rail 921 and a fixing block 922, the fixing block 922 is located on the front side of the slide rail 921, the movable seat 95 is slidably mounted on the slide rail 921, and the movable seat 95 is equipped with the fourth driving part 94; one end of the buffer rod 96 is mounted on the movable seat 95, and the other end of the buffer rod 96 is slidably mounted on the fixing block 922, the elastic element 97 is mounted on the outer periphery of the buffer rod 96, one end of the elastic element 97 abuts against the movable seat 95, and the other end of the elastic element 97 abuts against the fixing block 922. In this embodiment, the elastic element 97 is a spring. During operation, the third driving part 93 drives the fixed seat 92 to move towards the rotating shaft 51 and drives the moving seat 95 to move backward until the workpiece is inserted into the mounting boss 511. At this time, under the action of the reaction force, the moving seat 95 slides forward on the slide rail 921. At this time, the buffer rod 96 protrudes from the front side of the fixed block 922, and the elastic element 97 is in a compressed state, so that the workpiece can stop smoothly and prevent the workpiece from having a rigid collision with the rotating shaft 51.
