[0023] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0025] This application discloses an easy-to-use dispensing machine.

[0026] Reference Figure 1 A user-friendly dispensing machine includes a frame 1, a sliding frame 11 mounted on the frame 1, a dispensing machine body 2 mounted on the sliding frame 11, and a dispensing needle 21 mounted on the dispensing machine body 2. In use, the dispensing machine body 2 dispenses adhesive onto the product through the dispensing needle 21. The frame 1 is equipped with an adjustment component 3, a primary drive component 4, and a secondary drive component 5. The adjustment component 3 drives the dispensing machine body 2 to move closer to the product, and the primary drive component 4 and the secondary drive component 5 drive the dispensing machine body 2 to dispense adhesive onto the product.

[0027] Reference Figure 2The sliding frame 11 is slidably mounted on the frame 1. To improve the ease of sliding the sliding frame 11 on the frame 1, the adjustment assembly 3 includes an adjustment screw 31, which is vertically rotatably mounted on the frame 1. A sliding block 32 is provided on the sliding frame 11. One end of the sliding block 32 is mounted on the sliding frame 11. One end of the adjustment screw 31 passes through the sliding block 32, and the adjustment screw 31 is threadedly connected to the sliding block 32. In use, the adjustment screw 31 is rotated, and the adjustment screw 31 drives the sliding block 32 to slide on the frame 1.

[0028] Furthermore, a handwheel 33 is rotatably mounted on the frame 1, with its axis perpendicular to the axis of the adjusting screw 31. A drive gear 34 is mounted on the handwheel 33, which drives the drive gear 34 to rotate during use. A driven gear 35 is mounted on one end of the adjusting screw 31, meshing with the drive gear 34. During use, the handwheel 33 drives the sliding frame 11 to slide on the frame 1. When the dispensing machine body 2 needs to be used to dispense glue to the product, the handwheel 33 is rotated to move the dispensing machine body 2 closer to the product. Then, the first-stage drive assembly 4 and the second-stage drive assembly drive the dispensing machine body 2 to dispense glue. This shortens the sliding stroke of the dispensing machine body 2 on the frame 1, improving its dispensing efficiency.

[0029] Reference Figure 2 The primary drive assembly 4 includes a drive motor 41 and a drive gear 42. The drive motor 41 is mounted on the frame 1, and the drive gear 42 is mounted on the output shaft of the drive motor 41, and the drive gear 42 meshes with the driven gear 35. In use, the drive motor 41 drives the drive gear 42 to rotate forward or backward, thereby improving the ease of movement of the dispensing machine body 2 on the frame 1.

[0030] Reference Figure 3 After the primary drive assembly 4 moves the dispensing machine body 2 closer to the product, the secondary drive assembly 5 then moves the dispensing needle 21 on the dispensing machine body 2 closer to the product. The secondary drive assembly 5 includes a lifting motor 51 and a lifting screw 52. The lifting motor 51 is mounted on the sliding frame 11, and the lifting screw 52 is rotatably mounted on the sliding frame 11. One end of the lifting screw 52 passes through the dispensing machine body 2, and the lifting screw 52 is threadedly connected to the dispensing machine body 2. The lifting motor 51 drives the lifting screw 52 to rotate on the sliding frame 11. In use, as the lifting screw 52 rotates, the dispensing machine body 2 slides on the sliding frame 11.

[0031] Furthermore, a guide rod 53 is provided on the sliding frame 11. The guide rod 53 is arranged parallel to and spaced apart from the lifting screw 52. The guide rod 53 is installed on the sliding frame 11, and one end of the guide rod 53 passes through the dispensing machine body 2. The dispensing machine body 2 slides along the axial direction of the guide rod 53. This improves the stability of the dispensing machine body 2 sliding on the sliding frame 11.

[0032] When the dispensing machine body 2 dispenses glue to the product through the dispensing needle 21, in order to improve the accuracy of the position movement of the dispensing machine body 2, a positioning component 6 is provided on the sliding frame 11. The positioning component 6 includes a positioning block 61 and a positioning rod 62. The positioning rod 62 is vertically arranged, and one end of the positioning rod 62 is connected to the positioning block 61, and the other end passes through the sliding frame 11. The positioning block 61 slides and cooperates with the sliding frame 11 through the positioning rod 62.

[0033] A fixed plate 63 is provided on the sliding frame 11. One end of the positioning rod 62 passes through the fixed plate 63, and the positioning rod 62 slides in conjunction with the fixed plate 63. A positioning plate 64 is provided on the positioning rod 62. A return spring 65 is provided between the positioning plate 64 and the fixed plate 63. The return spring 65 is sleeved on the positioning rod 62, and one end of the return spring 65 is connected to the fixed plate 63, and the other end is connected to the positioning plate 64. Furthermore, a laser sensor 66 is installed on the sliding frame 11, and the laser sensor 66 faces the side closer to the positioning rod 62.

[0034] In operation, handwheel 33 drives drive gear 34 to rotate, which in turn drives adjusting screw 31 via driven gear 35. The sliding frame 11 slides towards the product via adjusting screw 31. When positioning block 61 presses against the product's surface, handwheel 33 stops rotating. Drive motor 41 drives drive gear 42 to rotate, which, by rotating forward or backward, moves sliding frame 11 further towards the product. As sliding frame 11 moves towards the product, positioning rod 62 moves towards laser sensor 66. When positioning rod 62 blocks laser sensor 66, drive motor 41 stops. Then, lifting motor 51 drives dispensing needle 21 on dispensing machine body 2 towards the product via lifting screw 52. After dispensing is complete, lifting motor 51 and drive motor 41 reverse, causing dispensing machine body 2 to reverse. This process repeats, significantly improving dispensing efficiency.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
