Description

Technical Field

[0001] This utility model relates to the field of dispensing equipment technology, and in particular to an automatic liquid silicone dispensing machine. Background Technology

[0002] A liquid silicone dispensing machine is a highly specialized industrial device designed to precisely and efficiently apply liquid silicone to specific locations on various products or components.

[0003] Traditional liquid silicone dispensing machines often use dispensing syringes that are prone to clogging when not in use due to dried-out residual silicone. Manual cleaning is not only inefficient but also difficult to ensure thorough cleaning, thus affecting the accuracy and quality of subsequent dispensing. Furthermore, the transition between feeding and cleaning processes relies heavily on manual operation, which is not only complex but also causes production interruptions. Therefore, we propose an automatic liquid silicone dispensing machine to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing liquid silicone dispensing machines, such as the inability to automatically clean the dispensing syringe, which leads to easy clogging of the dispensing syringe when not in use, and the lack of automatic switching between feeding and cleaning functions. Therefore, this invention proposes an automatic liquid silicone dispensing machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic liquid silicone dispensing machine includes a base, with a movable frame slidably connected to both sides of the base. Multiple dispensing syringes are mounted on one side of the movable frame, and each syringe has a material container fixedly connected to its top. A connector is fixedly mounted on one side of the base, and a flip plate is provided inside the connector. A first connecting tube corresponding to the multiple dispensing syringes is fixedly mounted through the flip plate. Feeding tubes are fixedly connected to the tops of the multiple material containers, and each feeding tube is fixedly connected to one end of a corresponding first connecting tube. A second connecting tube corresponding to the first connecting tube is fixedly mounted through the bottom of the connector, and the bottoms of the second connecting tubes are connected to an external liquid silicone delivery pump via flexible hoses. A third connecting tube corresponding to the first connecting tube is fixedly mounted through the top of the connector. The dispensing machine also includes…

[0007] The cleaning component, located on the base, is used to clean the dispensing syringe when not in use.

[0008] The plug-in assembly, mounted on the plug-in frame, is used to enable automatic switching between cleaning and feeding.

[0009] The drive assembly, located on the base, is used to enable multi-axis movement of multiple dispensing syringes.

[0010] In one possible design, the cleaning assembly includes a water pump, which is fixedly mounted on the top of the base. The water pump's inlet is connected to an external water source via a water pipe, and the water pump's outlet is fixedly connected to a connecting water pipe. Multiple third connecting pipes are all connected to the connecting water pipe.

[0011] In one possible design, the plug-in assembly includes a first threaded rod rotatably disposed inside the plug-in frame. The bottom inner wall of the plug-in frame and the same slide rod are fixedly connected to each other. Movable blocks are slidably disposed inside the plug-in frame and on the slide rod. The two ends of the flip plate are rotatably connected to the two movable blocks via rotating shafts. The first threaded rod is threaded through the movable blocks located inside the plug-in frame. A first motor is fixedly disposed on the top of the plug-in frame. The output end of the first motor is fixedly connected to the top of the first threaded rod. A flipping assembly for driving the flipping plate to flip is disposed on one side of the movable block located on the slide rod.

[0012] In one possible design, the flipping assembly includes a motor housing, which is fixedly mounted on one side of the moving block located on the slide bar. A second motor is fixedly mounted inside the motor housing, and transmission gears are fixedly sleeved on the output end of the second motor and on one of its rotating shafts. The two transmission gears are meshed and connected.

[0013] In one possible design, the drive assembly includes a second lead screw, and grooves are provided on both sides of the base. Both ends of the movable frame are located in the grooves and slidably connected to them. The second lead screw is rotatably disposed inside one of the grooves and its threads pass through the movable frame. A third motor is fixedly disposed on one side of the base, and the output end of the third motor is fixedly connected to the second lead screw. An X-axis drive mechanism is slidably disposed inside the movable frame, and a Y-axis drive mechanism is slidably disposed on one side of the X-axis drive mechanism. Multiple dispensing syringes are fixedly connected to the slider in the Y-axis drive mechanism via a fixing block.

[0014] In one possible design, a wastewater collection tank is fixedly embedded in the top of the base, and a placement platform is provided on one side of the wastewater collection tank at the top of the base.

[0015] In one possible design, multiple second connecting pipes and multiple third connecting pipes are equipped with electric valves.

[0016] In one possible design, multiple sealing rings are fitted on multiple first connecting pipes, and the inner diameters of multiple second connecting pipes and multiple third connecting pipes are larger than the outer diameters of multiple first connecting pipes, so that multiple first connecting pipes can be inserted into the corresponding second or third connecting pipes to achieve insertion.

[0017] In this application, firstly, when the equipment is not in use and the dispensing syringe needs to be cleaned, the water pump is started. The water pump is fixed on the top of the base, and its inlet is connected to an external water source through a water pipe. The water pump draws out water and delivers it to multiple third connecting pipes through the connecting water pipe. The water flows into the first connecting pipe through the third connecting pipe, and then into the material tank and the dispensing syringe to rinse the residual liquid silicone inside. The wastewater after rinsing drips from the dispensing syringe into the wastewater collection tank on the top of the base for collection.

[0018] When switching from cleaning to feeding mode, the first motor is activated. The first motor is fixed to the top of the connector frame. The output of the first motor drives the first threaded rod to rotate. Since the threaded rod passes through one of the moving blocks and the moving block can slide on the slide rod, the moving block moves on the slide rod when the first threaded rod rotates. The two ends of the flip plate are rotatably connected to the two moving blocks through rotating shafts. Therefore, the movement of the moving blocks will drive the flip plate to move. When the flip plate moves to the appropriate position, the second motor in the motor box is activated. The motor box is fixed to one side of the moving block located on the slide rod. The output of the second motor meshes with two transmission gears on one of the rotating shafts. The rotation of the second motor drives the transmission gears to rotate, which in turn drives the flip plate to rotate around the rotating shaft. After the rotation is completed, the first motor continues to drive the flip plate to move, so that the first connecting pipe can be inserted into the second or third connecting pipe, realizing the automatic switching between feeding and cleaning. At the same time, the electric valves on the multiple second and third connecting pipes can control the opening and closing of the pipeline as needed to ensure the smooth progress of the switching process.

[0019] When it is necessary to control the dispensing syringe for dispensing operations, the third motor is activated. The third motor is fixed to one side of the base, and its output drives the second lead screw to rotate. Since the second lead screw is threaded through the moving frame, and both ends of the moving frame are located in the sliding grooves on both sides of the base and are slidably connected to the sliding grooves, the moving frame will slide in the sliding grooves on both sides of the base when the second lead screw rotates, realizing the movement of the dispensing syringe in one direction. At the same time, the X-axis drive mechanism and Y-axis drive mechanism on the top of the base cooperate with each other. By controlling the movement of the sliders in the X-axis drive mechanism and Y-axis drive mechanism, multiple dispensing syringes can move flexibly in the X-axis and Y-axis directions. Multiple dispensing syringes are fixedly connected to the sliders in the Y-axis drive mechanism through fixed blocks, so that the dispensing syringes can move flexibly in three-dimensional space according to the dispensing requirements to complete complex dispensing operations.

[0020] Beneficial effects: The automatic liquid silicone dispensing machine of this utility model can automatically clean multiple dispensing syringes when the equipment is not in use by setting up a cleaning component, which avoids the dispensing syringes from being blocked by dried residual silicone, greatly improves the service life of the dispensing syringes, ensures the accuracy and quality of subsequent dispensing, reduces the workload of manual cleaning, and improves production efficiency.

[0021] In this utility model, the automatic liquid silicone dispensing machine achieves automatic switching between cleaning and feeding through the design of plug-in components, reducing the tedious steps of manual connection, lowering the possibility of operational errors, ensuring the continuity and stability of the production process, and improving production efficiency and product quality.

[0022] In this utility model, the automatic liquid silicone dispensing machine enables multiple dispensing syringes to move in multiple axes through a drive component, which meets the diverse and high-precision dispensing needs of complex products, improves the flexibility and adaptability of dispensing, and expands the application range of the equipment.

[0023] In this invention, by setting up a cleaning component, multiple dispensing syringes can be automatically cleaned when the equipment is not in use, avoiding blockage caused by dried residual silicone. The design of the plug-in component realizes the automatic switching between cleaning and feeding, ensuring the continuity and stability of the production process.
