[0027] Reference Figure 1 This utility model provides an embodiment of a high-precision dispensing device, comprising a fixing mechanism 1 and a base plate 9. A second lead screw 10 is rotatably mounted inside the upper end of the base plate 9. A second motor 12 is fixedly mounted on one side of the base plate 9. Two fixing posts 5 are fixedly mounted on the upper end of the base plate 9. The main body 102 is threaded around the second lead screw 10. A fixing frame 11 is slidably mounted around the two fixing posts 5. A first lead screw 6 is rotatably mounted inside the fixing frame 11. A dispensing mechanism 4 is threaded around the first lead screw 6. A first motor 7 is fixedly mounted on one side of the fixing frame 11. A first fixing bracket 3 is fixedly mounted on the upper end of the two fixing posts 5. A first electric push rod 2 is fixedly mounted inside the first fixing bracket 3. A second fixing bracket 8 is fixedly mounted between the first fixing bracket 3 and the base plate 9.
[0028] Specifically, starting motor 12 drives screw 10 to rotate, which facilitates moving the position of fixing mechanism 1 and allows for dispensing adhesive at different positions on the object; starting electric push rod 2 drives frame 11 to move up and down, which facilitates dispensing adhesive at different heights on the object; starting motor 7 drives screw 6 to rotate, which facilitates dispensing adhesive at different positions; the two fixing posts 5 help to limit the position of frame 11.
[0029] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5The fixing mechanism 1 includes a main body 102. A first gear 110 and a second gear 111 are rotatably mounted on one side of the main body 102. A second rack 112 and a third rack 115 are slidably engaged on one side of the main body 102. A first fixing rod 104 is fixedly mounted at the ends of the second rack 112 and the third rack 115 that are far apart from each other. The second rack 112 and the third rack 115 mesh with the first gear 110 and the second gear 111, respectively. Two No. 3 gears 117 are rotatably arranged on one side of the interior of the main body 102. Two No. 4 racks 118 are slidably arranged on the side of the main body 102 near the No. 3 gears 117. A snap-fit block 108 is fixedly arranged inside the main body 102. A No. 1 rack 109 is slidably snap-fitted around the upper end of the snap-fit block 108. A No. 2 fixing rod 107 is fixedly arranged at one end of each of the two No. 4 racks 118. Two No. 3 fixing rods 107 are fixedly arranged at the end of the No. 1 rack 109 away from the No. 2 fixing rod 107. Fixed rod 113, rack 112, rack 115, gear 110, gear 111, and two fixed rods 104 are each provided in two sets. Fixed plates 101 are slidably connected between each pair of the four fixed rods 104. Four springs 103 connect the fixed rods 104 and the two fixed plates 101. Gears 110 and 111 mesh with rack 109. Two racks 118 are respectively connected to the two fixed rods 113. A No. 3 gear 117 meshes with the two No. 2 fixing rods 107 and a No. 2 fixing plate 105 is slidably arranged around them. Two No. 2 springs 106 are connected between the two No. 2 fixing rods 107 and the No. 2 fixing plate 105. A No. 3 fixing plate 119 is slidably arranged around the two No. 3 fixing rods 113. Two No. 3 springs 114 are connected between the No. 3 fixing plate 119 and the two No. 3 fixing rods 113. A No. 2 electric push rod 116 is fixedly arranged at one end inside the main body 102.
[0030] Specifically, activating the second electric push rod 116 pushes the first rack 109, which in turn moves the two third fixing rods 113 and the third fixing plate 119. The first rack 109 then rotates the two third gears 117, which in turn move the two fourth racks 118, the two second fixing rods 107, and the second fixing plate 105, facilitating the fixation of the object via the second fixing plate 105 and the third fixing plate 119. Furthermore, the first rack 109 also rotates the two first gears 110 and the second gear 111, which in turn drive... The four racks 112 and 115 move closer together, which in turn moves the two fixing plates 101 closer together. This is beneficial for fixing the object from the other two sides, and for fixing the object from four directions, improving stability and reducing production costs. When the two fixing plates 101 have fixed the object, but the fixing plates 105 and 119 have not yet contacted the object surface, the springs 106 and 114 can be squeezed to make it continue to move. This is beneficial for fixing objects of different sizes and improving the practicality of the device. The snap-fit block 108 is beneficial for installing the rack 109.
[0031] Working principle: When in use, the second electric push rod 116 is activated to push the first rack 109. The first rack 109 drives the third fixing rod 113 and the third fixing plate 119 to move, which in turn drives the two third gears 117 to rotate. The two third gears 117 drive the two fourth racks 118, the two second fixing rods 107, and the second fixing plate 105 to move, which helps to fix the object from two directions. In addition, the first rack 109 also drives the first gear 110 and the second gear 111 to rotate. The first gear 110 and the second gear 111 drive the second rack 112 and the third rack 115 to move, which helps to move the two first fixing plates 101, which helps to fix the object from two other directions.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
