[0003] Existing devices are typically only suitable for medicine bottles of specific height and shape, making it difficult to adapt to products of various specifications. This limits the versatility and flexibility of the equipment. Different sizes of medicine bottles require precise height positioning; otherwise, the marking position may be too high or too low, or even damage the medicine bottle. Therefore, we need to propose a positioning device for laser marking of medicine bottles. Utility Model Content
[0004] The purpose of this invention is to provide a positioning device for laser marking medicine bottles. Rotating a first rotating disk drives a bidirectional lead screw to rotate, causing a threaded motion between the lead screw and a moving rod, which in turn moves the two moving rods closer together or further apart. The moving rods then move a guide frame, which guides the medicine bottle. The guide frame has markings on its side wall for easy observation of the distance between the two moving rods. Rotating a second rotating disk drives a screw to rotate, causing a threaded motion between the screw and a fixed plate, controlling the height of a height-limiting plate. The guide rod guides the height-limiting plate as it rises and falls. The guide rod also has markings on its outer side for easy observation of the height-limiting plate's height. This device limits the left and right sides and height of the medicine bottle, thus solving the problems mentioned in the background art.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-4 This utility model provides a technical solution:
[0022] A positioning device for laser marking medicine bottles includes a conveyor belt 1. A fixed frame 2 is fixedly connected to the upper end of the conveyor belt 1. A bidirectional lead screw 3 is rotatably connected inside the fixed frame 2. One end of the bidirectional lead screw 3 passes through the fixed frame 2 and is fixedly connected to a first rotating disk 4. Two symmetrically distributed moving rods 5 are threadedly connected to the outer side of the bidirectional lead screw 3. Both moving rods 5 are rotatably connected to the fixed frame 2. Guide frames 6 are fixedly connected to the lower ends of both moving rods 5. A fixed plate 7 is fixedly connected to the side wall of the fixed frame 2. A screw 8 is threadedly connected inside the fixed plate 7. A second rotating disk 9 is fixedly connected to the upper end of the screw 8. A height limiting plate 10 is rotatably connected to the lower end of the screw 8. Two symmetrically distributed guide rods 11 are fixedly connected to the upper end of the height limiting plate 10. The two guide rods 11 are slidably connected to the fixed plate 7.
[0023] For example, rotating the first rotating disk 4 causes the bidirectional lead screw 3 to rotate, resulting in a threaded movement between the bidirectional lead screw 3 and the moving rod 5, causing the two moving rods 5 to move closer or further apart. The moving rods 5 then move the guide frame 6, which guides the medicine bottle. The guide frame 6 has markings on its side wall for easy observation of the distance between the two moving rods 5. Rotating the second rotating disk 9 causes the screw 8 to rotate, resulting in a threaded movement between the screw 8 and the fixed plate 7, controlling the height of the height limiting plate 10. The guide rod 11 guides the height limiting plate 10 as it rises and falls. The guide rod 11 has markings on its outer side for easy observation of the height of the height limiting plate 10. The device limits the left and right sides and the height of the medicine bottle.
[0024] The conveyor belt 1 has two symmetrically distributed first telescopic rods 12 inside, and clamping plates 13 are fixedly connected to the output ends of the two first telescopic rods 12.
[0025] For example, the first telescopic rod 12 drives the clamping plate 13 to move, and the two first telescopic rods 12 clamp the medicine bottle.
[0026] Two symmetrically distributed second telescopic rods 14 are fixedly connected to the side wall of the conveyor belt 1. A lifting plate 15 is fixedly connected to the output end of the two second telescopic rods 14. A mounting plate 16 is slidably connected inside the lifting plate 15. Multiple through holes 17 are evenly distributed inside the mounting plate 16. Fixing bolts 18 are provided inside the two through holes 17. The two fixing bolts 18 are threadedly connected to the lifting plate 15. A control plate 19 is fixedly connected to the lower end of the lifting plate 15. The control plate 19 is electrically connected to the first telescopic rod 12.
[0027] For example, the second telescopic rod 14 controls the height of the lifting plate 15, and the fixing bolts 18 are installed in different positions by installing in different through holes 17. The mounting plate 16 fixes the control plate 19. The second telescopic rod 14 controls the height of the lifting plate 15, the mounting plate 16 and the control plate 19.
[0028] Working principle: When using this utility model, the medicine bottle is placed on the conveyor belt 1. The first rotating disk 4 is rotated, which drives the bidirectional lead screw 3 to rotate. The bidirectional lead screw 3 and the moving rod 5 have a threaded movement, which drives the two moving rods 5 to move closer or further apart. The moving rods 5 drive the guide frame 6 to move. The guide frame 6 guides the medicine bottle. The guide frame 6 has a scale on its side wall to make it easy to observe the distance between the two moving rods 5. The second rotating disk 9 is rotated, which drives the screw 8 to rotate. The screw 8 and the fixed plate 7 have a threaded movement, which controls the height of the height limit plate 10. The guide rod 11 guides the height limit plate 10 when it is raised or lowered. The guide rod 11 has a scale on its outer side to make it easy to observe the height of the height limit plate 10. The device limits the left and right sides and the height of the medicine bottle.
[0029] The medicine bottle contacts the control panel 19, which controls the first telescopic rod 12 to work. At the same time, the controller controls the conveyor belt 1 to stop working. After the marking is completed, the first telescopic rod 12 is released, and the controller controls the second telescopic rod 14 to rise. The controller then controls the conveyor belt 1 to work and transport the marked medicine bottle out. The first telescopic rod 12 limits the subsequent medicine bottles. The second telescopic rod 14 is lowered, and the first telescopic rod 12 is released, repeating the process of fixing the medicine bottle.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
