Description
Technical Field
[0001] This utility model relates to the field of dispensing machine technology, specifically a positioning component for a fluid dispensing machine. Background Technology
[0002] The positioning components of a fluid dispensing machine are a key part of ensuring the accuracy and repeatability of the dispensing process. These components help determine the position of the dispensing head, ensuring that each dispensing operation is performed in the correct location.
[0003] For existing positioning components used in dispensing machines, refer to Chinese Utility Model Patent No. CN220004666U, which discloses an IC card dispensing machine with a positioning mechanism, relating to the field of IC card dispensing technology.

[0012] As a preferred positioning component for a fluid dispensing machine according to this utility model, a rectangular shell is fixedly connected to both the front and rear sides of the top of the mounting plate. The two rectangular shells are arranged parallel to the mounting plate. A horizontally arranged airbag tube is fixedly connected inside each of the two rectangular shells. A plurality of equidistant abutment rods are slidably connected to one side of the two airbag tubes that are close to each other. The abutment rods extend to the outside of the rectangular shell at the end away from the airbag tube and are slidably connected thereto.
[0013] As a preferred positioning component for a fluid dispensing machine according to this utility model, the two airbag tubes are fixedly connected to each other on one side with a plurality of equally spaced sealing rings.

[0022] Please see Figures 1-3 A positioning component for a fluid dispensing machine includes a fluid dispensing machine body 1 and a positioning component 2 disposed at the top center of its worktable. The positioning component 2 includes a mounting plate 201, and support plates 210 are fixedly connected to the left and right sides of the bottom of the mounting plate 201. The bottoms of the two support plates 210 are fixedly connected to the left and right sides of the top of the worktable of the fluid dispensing machine body 1.
[0023] Furthermore, horizontally arranged sliding grooves 202 are provided on both the front and rear sides of the top of the mounting plate 201. The two sliding grooves 202 are arranged parallel to the mounting plate 201. U-shaped rods 207 are correspondingly arranged on the left and right sides of the top of the mounting plate 201. Positioning plates 208 are fixedly connected to the side of the U-shaped rods 207 that are close to each other. The bottom of the two positioning plates 208 is slidably connected to the left and right sides of the top of the mounting plate 201. The bottom of the two U-shaped rods 207 extends to the bottom of the mounting plate 201 and is slidably connected to the inner wall of the sliding grooves 202. The moving path of the two U-shaped rods 207 and the two positioning plates 208 is from the left and right sides of the mounting plate 201 towards its center.
[0024] The mounting plate 201 serves as the basic platform, with horizontally arranged sliding grooves 202 on the front and rear sides of the top to guide the movement of the U-shaped rod 207. The support plate 210 is fixed to the bottom left and right sides of the mounting plate 201 and connected to the top of the worktable of the fluid dispensing machine body 1, providing a stable support structure.
[0025] Each U-shaped rod 207 passes through the slide groove 202, and its bottom is slidably connected to the inner wall of the slide groove 202, allowing them to move along the slide groove 202 toward or away from the center of the mounting plate 201. The positioning plate 208 is fixed on the U-shaped rod 207 and moves with the U-shaped rod 207, thereby achieving the clamping or releasing of the object to be processed.
[0026] Furthermore, a central gear 203 is rotatably connected at the bottom center of the mounting plate 201, and toothed plates 206 are meshed on both the front and rear surfaces of the central gear 203. The top of the front toothed plate 206 is slidably connected to the left front end of the bottom of the mounting plate 201.
[0027] A central gear 203 is positioned at the center of the bottom of the mounting plate 201 and is rotatable. Toothed plates 206 are positioned at the front and rear and mesh with the central gear 203. When the central gear 203 rotates, it drives the front and rear toothed plates 206 to move in opposite directions. The top of the front toothed plate 206 is slidably connected to the front left end of the bottom of the mounting plate 201 to ensure smooth movement along a predetermined path. The top of the rear toothed plate 206 is slidably connected to the rear right end of the bottom of the mounting plate 201, ensuring smooth movement along a predetermined path.
[0028] Furthermore, the top of the rear toothed plate 206 is slidably connected to the rear right end of the bottom of the mounting plate 201, and one end of the two U-shaped rods 207 extends to the bottom of the mounting plate 201 and is fixedly connected to the connecting rod 209.
[0029] The other end of the connecting rod 209 is fixedly connected to one side of each of the two toothed plates 206. When the toothed plates 206 move under the action of the central gear 203, they will drive the U-shaped rod 207 to move synchronously.
[0030] Furthermore, the ends of the two connecting rods 209 away from the bottom of the U-shaped rod 207 are fixedly connected to one side of the two toothed plates 206 respectively, and the other ends of the bottom of the two U-shaped rods 207 are fixedly connected to baffles, with the top of the baffles slidably connected to the bottom of the mounting plate 201.
[0031] The top of the baffle is slidably connected to the bottom of the mounting plate 201 to ensure that the U-shaped rod 207 and the positioning plate 208 on it can move horizontally stably and smoothly.
[0032] Furthermore, a U-shaped frame 204 is provided below the center of the bottom of the mounting plate 201. The U-shaped frame 204 is perpendicular to the mounting plate 201. The front and rear tops of the U-shaped frame 204 are fixedly connected to the front and rear ends of the bottom center of the mounting plate 201, respectively. A power motor 205 is fixedly connected to the center of the bottom of the inner wall of the U-shaped frame 204. The output shaft of the power motor 205 is fixedly connected to the inner wall of the central gear 203.
[0033] Driven by a power motor 205, the central gear 203 has toothed plates 206 meshing on both its front and rear surfaces. When the central gear 203 rotates, it will drive the two toothed plates 206 to move in opposite directions. The movement of the toothed plates 206 is transmitted to the U-shaped rod 207 through the connecting rod 209, thereby adjusting the position of the positioning plate 208.
[0034] Furthermore, rectangular shells 211 are fixedly connected to the front and rear sides of the top of the mounting plate 201. The two rectangular shells 211 are arranged parallel to the mounting plate 201. Horizontally arranged airbag tubes 212 are fixedly connected inside the two rectangular shells 211. Multiple abutment rods 213 are equidistantly connected to one side of the two airbag tubes 212 that are close to each other. The ends of the multiple abutment rods 213 that are away from the airbag tubes 212 extend to the outside of the rectangular shells 211 and are slidably connected to them.
[0035] A rectangular shell 211 is located on the front and rear sides of the top of the mounting plate 201, and is arranged parallel to the mounting plate 201. The rectangular shell 211 not only provides a mounting position but also protects the internal components. The airbag tube 212 is fixed inside the rectangular shell 211 and is arranged horizontally. The airbag tube 212 can change its expansion degree by inflating or deflating, thereby adjusting the position of the abutment rod 213 connected to it. As the airbag tube 212 expands or contracts, the abutment rod 213 can extend outward or retract inward to contact and support different parts of the object to be processed.
[0036] Furthermore, two airbag tubes 212 are fixedly connected to each other on one side with multiple equally spaced sealing rings 214. The inner walls of the multiple sealing rings 214 are slidably connected to the surfaces of multiple abutment rods 213. Each airbag tube 212 is fixedly connected to an elastic telescopic rod 215 at its right end. The end of the elastic telescopic rod 215 away from the airbag tube 212 extends to the right side of the rectangular shell 211 and is slidably connected thereto. A diversion pipe 216 is provided on the lower right side of the mounting plate 201. The diversion pipe 216 is perpendicular to the mounting plate 201.
[0037] The inner wall of the sealing ring 214 is slidably connected to the surface of the abutment rod 213. The function of the sealing ring 214 is to ensure that the airbag tube 212 maintains good airtightness during inflation or deflation, while allowing the abutment rod 213 to slide smoothly.
[0038] Furthermore, one side of the diversion tube 216 is fixedly connected to one side of the right support plate 210, and the ends of the two elastic telescopic rods 215 away from the airbag tube 212 are fixedly connected to the front and rear ends of the top of the diversion tube 216. A connecting tube 217 is fixedly connected to the center of the right side of the diversion tube 216. An air pump 218 is fixedly connected to the end of the connecting tube 217 away from the diversion tube 216. A base plate 219 is fixedly connected to the bottom of the air pump 218, and a fluid dispensing machine body 1 is fixedly connected to one side of the base plate 219.
[0039] Connecting pipe 217 is fixed at the center of the right side of the diverter pipe 216 and is used to connect to the suction end of the air pump 218. The air pump 218 is connected to the diverter pipe 216 through connecting pipe 217 and is responsible for providing the required gas pressure to the airbag tube 212 or performing exhaust operations to adjust the position of the abutment rod 213. A base plate 219 is fixed to the bottom of the air pump 218. One side of the base plate 219 is fixedly connected to the fluid dispensing machine body 1 to ensure the stability and integration of the entire system.
[0040] Air pump 218 supplies or evacuates air to distribution pipe 216 via connecting pipe 217. Distribution pipe 216 evenly distributes the air to the airbag tubes 212 on both sides. When the airbag tubes 212 are inflated, they push the abutment rod 213 outward; when the airbag tubes 212 are deflated, the abutment rod 213 retracts inward. Sealing ring 214 ensures airtightness during sliding. Elastic telescopic rod 215 provides additional support for airbag tubes 212 and abutment rod 213, ensuring they maintain linear movement during operation and increasing the stability and reliability of the system.
[0041] Before the system starts, all the abutment rods 213 are in the retracted state, and the U-shaped rod 207 and its positioning plate 208 are also in a relatively wide position, ready to receive the object to be processed. The object to be processed is placed on the mounting plate 201, located between the two positioning plates 208.
[0042] The power motor 205 starts, driving the central gear 203 to rotate. The central gear 203 drives the front and rear gear plates 206 to move inward (closer to the workpiece). Through the connecting rod 209, the U-shaped rod 207 and the positioning plate 208 move closer to the workpiece until the positioning plate 208 contacts both sides of the workpiece, completing the initial positioning.
[0043] The air pump 218 starts working, supplying air to the distribution pipe 216 through the connecting pipe 217. The distribution pipe 216 evenly distributes the air to the airbag tubes 212 on both sides, causing the airbag tubes 212 to inflate. As the airbag tubes 212 inflate, they push the abutment rod 213 outward until it contacts different parts of the workpiece surface, providing all-around support. Throughout the process, the sealing ring 214 ensures the good airtightness of the airbag tubes 212 while allowing the abutment rod 213 to slide smoothly, ensuring the stability and reliability of the system. The elastic telescopic rod 215 provides additional support when the airbag tubes 212 inflate, helping to maintain the stability of the airbag tubes 212 and the abutment rods 213 on them, preventing displacement or deformation.
[0044] After positioning is completed, the fluid dispensing machine body 1 begins the dispensing operation. Once dispensing is finished, the air pump 218 stops supplying air and extracts the gas from the air bladder tube 212 through the suction end, causing the abutment rod 213 to retract to its initial position. The power motor 205 rotates in the opposite direction, causing the positioning plate 208 to return to a wider position, facilitating the removal of the processed workpiece. This design combines the advantages of mechanical transmission and pneumatic control, enabling efficient and flexible handling of workpieces of various shapes and sizes, significantly improving the applicability and working efficiency of the fluid dispensing machine.
[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
