Description

Technical Field

[0001] This utility model relates to the field of filling equipment technology, and in particular to a filling device for a multi-specification silicon wafer cutting liquid container. Background Technology

[0002] The application of silicon wafer cutting fluid in the photovoltaic and semiconductor industries is becoming increasingly widespread, and its filling accuracy and efficiency directly affect production quality and cost. Currently, most common filling devices use conveyor belts with fixed filling heads. However, during high-speed filling, containers are prone to shifting or tipping, leading to decreased filling accuracy and liquid splashing. Furthermore, the turntable fixing structure of traditional filling equipment often uses bolts for direct locking, which is inconvenient for disassembly and maintenance, lacks adjustment flexibility, and is difficult to adapt to the filling needs of various container sizes. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to overcome the problem that the turntable fixing structure of the existing filling equipment is mostly directly locked with bolts, which is inconvenient to disassemble and maintain, has poor adjustment flexibility, and is difficult to adapt to the filling needs of multi-specification containers, a filling device for multi-specification silicon wafer cutting liquid containers is provided.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a filling device for multi-specification silicon wafer cutting fluid containers, comprising: The feeding mechanism is used to transport the containers to be filled to the filling mechanism; A filling mechanism is used to inject silicon wafer cutting fluid into a container. The output end of the feeding mechanism is connected to the input end of the filling mechanism. The filling mechanism includes a frame and a filling component and a rotating component mounted on the frame. The rotating component includes a turntable, a mounting base, a fixed base, and a motor. The mounting base and the frame are rotatably connected, and the motor and the frame are fixedly connected. The output end of the motor is drivenly connected to the mounting base. The turntable is sleeved on the mounting base. The fixed base and the mounting base are fitted together and clamp the turntable. Several receiving slots for placing containers are opened along the circumference of the turntable. The filling mechanism outputs the filled container. The output end of the filling mechanism and the input end of the discharging mechanism are connected. Through the cooperation of the rotating component and the receiving tank, the container is kept in a fixed position during the filling process to avoid displacement or tipping, thus ensuring the accuracy and consistency of the filled liquid. The fixed seat and the mounting seat adopt an interlocking hook structure to realize the quick replacement of the turntable and the adjustment of the limit mechanism to adapt to different specifications of containers, thereby increasing the applicability of the filling device.

[0005] To address the issues of complex connection structure between the turntable and the mounting base, inconvenient disassembly and assembly, and high maintenance costs, a further improvement is made, including a fitting cavity on the mounting base, with fitting protrusions formed on the inner wall of the fitting cavity, and the bottom surface of the fitting protrusions serving as the fitting surface. The bottom surface of the fixed base has a fixed hook that mates with the mating surface. The fixed hook has a hooking surface for hooking the mating surface. The fixed hook and the mating protrusion are mated and connected.

[0006] To address the issue of fixed structures easily loosening under vibration, thus affecting long-term operational stability, the system further includes at least two oppositely arranged fixing hooks on the fixed base, with the two oppositely arranged fixing hooks connected by a connector. A control rod is elastically slidably mounted on the fixed base. The top of the control rod protrudes from the top surface of the fixed base. The control rod is in contact with the connector, and both the connector and the fixing hook can produce rigid deformation.

[0007] To address the issues of difficulty in resetting the control lever and inconvenience in operation, the control lever is further equipped with an elastic element, one end of which is fixedly connected to a fixed base, and the other end is fixedly connected to the control lever.

[0008] To address the issue of container misalignment during transport, which affects filling accuracy, a limit mechanism is further incorporated into both the feeding and discharging mechanisms to control the container's position.

[0009] To address the issues of cumbersome adjustment and inability to quickly adapt to different bottle shapes in traditional limiting mechanisms, a further proposed limiting mechanism includes an adjustment component and two limiting rods. The end of the connecting rod is connected to the adjustment end of the adjustment component, which is used to adjust the distance between the two limiting rods. The adjustment assembly includes an adjustment screw, two adjustment seats, and two connecting seats. The limit rod and the connecting seat correspond one-to-one, and the connecting seat and the adjustment seat correspond one-to-one. The adjustment screw is rotatably connected to the feeding mechanism / discharging mechanism. The adjustment screw has threaded sections at both ends, and the threads of the threaded sections at both ends of the adjustment screw have opposite helical directions. The threaded sections are threadedly connected to the adjustment seats. The connecting seats are rotatably connected to their corresponding adjustment seats, and the limit rods are fixedly connected to their corresponding connecting seats.

[0010] The beneficial effects of this utility model are as follows: This utility model provides a filling device for multi-specification silicon wafer cutting fluid containers. The feeding mechanism transports empty bottles to the turntable receiving groove of the filling mechanism. The limiting mechanism adjusts the spacing to fix the container position. Through the cooperation of the rotating component and the receiving groove, the container maintains a fixed position during the filling process, avoiding displacement or tipping, and ensuring the accuracy and consistency of the filled liquid. The fixed seat and the mounting seat adopt an interlocking hook structure to realize the quick replacement of the turntable and the adjustment of the spacing of the limiting mechanism to adapt to containers of different specifications, thereby increasing the applicability of the filling device.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0015] like Figure 1 This is a schematic diagram of the structure of this utility model, a filling device for multi-specification silicon wafer cutting fluid containers, comprising: Feeding mechanism 1 is used to transport the container to be filled to the filling mechanism 2; The filling mechanism 2 is used to inject silicon wafer cutting liquid into a container. The output end of the feeding mechanism 1 is connected to the input end of the filling mechanism 2. The filling mechanism 2 includes a frame and a filling component and a rotating component mounted on the frame. The rotating component includes a turntable 21, a mounting base 22, a fixed base 23, and a motor 24. The mounting base 22 is rotatably connected to the frame. The motor 24 is fixedly connected to the frame. The output end of the motor 24 is drively connected to the mounting base 22. The turntable 21 is sleeved on the mounting base 22. The fixed base 23 is fitted and connected to the mounting base 22. The fixed base 23 and the mounting base 22 clamp the turntable 21. The turntable 21 has a plurality of receiving slots 211 for placing containers along its circumference. The filling component has a filling head. The filling mechanism 2 and the discharging mechanism 3 are used to output the filled containers. The output end of the filling mechanism 2 and the input end of the discharging mechanism 3 are connected. The feeding mechanism 1 transports the empty bottles to the receiving groove of the turntable 21 of the filling mechanism 2. The limiting mechanism 4 adjusts the spacing to fix the position of the container. Through the cooperation of the rotating component and the receiving groove 311, the container is kept in a fixed position during the filling process to avoid displacement or tipping, and to ensure the accuracy and consistency of the filled liquid. The fixed seat 23 and the mounting seat 22 adopt an interlocking hook structure to realize the quick replacement of the turntable and the adjustment of the spacing of the limiting mechanism to adapt to containers of different specifications, thereby increasing the applicability of the filling device.

[0016] like Figure 3 As shown, the mounting base 22 has a fitting cavity 221, and a fitting protrusion 222 is formed on the inner wall of the fitting cavity 221. The bottom surface of the fitting protrusion 222 is a fitting surface 223. The bottom surface of the fixing base 23 has a fixing hook 231 that mates with the fitting surface 223. The fixing hook 231 has a hooking surface 232 for hooking the fitting surface 223. The fixing hook 231 and the fitting protrusion 222 are fitted together. The fitting protrusion 222 mates with the hooking surface of the fixing hook 231 to achieve quick assembly and disassembly and simplify the maintenance process. The bottom surface of the fixing hook 231 and the top surface of the fitting protrusion 222 both have guide slopes.

[0017] like Figure 3 As shown, the fixing base 23 has at least two oppositely arranged fixing hooks 231, and the two oppositely arranged fixing hooks 231 are connected by a connector 233. A control rod 234 is elastically slidably mounted on the fixed base 23. The top of the control rod 234 protrudes from the top surface of the fixed base 23. The control rod 234 contacts the connector 233. Both the connector and the fixing hook 231 can generate rigid deformation. The elastic control rod 234 and the connector 233 are designed to enhance structural rigidity and ensure reliable connection during high-speed operation.

[0018] like Figure 3 As shown, an elastic element 235 is sleeved on the control lever 234. One end of the elastic element 235 is fixedly connected to the fixed base 23, and the other end is fixedly connected to the control lever 234. The elastic element 235 provides an automatic reset function, which improves the convenience and safety of operation. The elastic element 235 is a spring.

[0019] like Figure 5 As shown, both the feeding mechanism 1 and the discharging mechanism 3 are equipped with limiting mechanisms 4. The limiting mechanisms 4 are used to control the position of the container. The limiting mechanisms 4 dynamically adjust the position of the container and the size of the container to ensure accurate docking of the filling interface.

[0020] like Figure 5As shown, the limiting mechanism 4 includes an adjusting assembly and two limiting rods 41. The end of the connecting rod is connected to the adjusting end of the adjusting assembly. The adjusting assembly is used to adjust the distance between the two limiting rods 41. The adjustment assembly includes an adjustment screw 42, two adjustment seats 43, and two connecting seats 44. The limiting rod 41 corresponds to the connecting seat 44, and the connecting seat 44 corresponds to the adjustment seat 43. The adjustment screw 42 is rotatably connected to the feeding mechanism 1 / discharging mechanism 3. The adjustment screw 42 has threaded sections at both ends, and the threaded sections at both ends of the adjustment screw 42 have opposite thread directions. The threaded sections are threadedly connected to the adjustment seats 43. The connecting seats 44 are rotatably connected to their corresponding adjustment seats 43. The limiting rod 41 is fixedly connected to its corresponding connecting seat 44. The bidirectional threaded structure of the adjustment screw 42 enables flexible adjustment of the spacing between the limiting rods, improving the versatility of the equipment.

[0021] Working process: The feeding mechanism 1 transports empty bottles to the turntable receiving slot of the filling mechanism 2. The limiting mechanism adjusts the spacing to fix the position of the container. The motor 24 drives the mounting base 22 to rotate, which drives the turntable 21 and the container to pass under the filling component in sequence. The cutting fluid is injected into the bottle through the filling head. The filled container rotates with the turntable 21 to the position of the discharge mechanism 3, which transports it to the next process to realize continuous operation. When the turntable needs to be replaced or cleaned, press the control lever 234 to disengage the fixing hook 231 from the engagement protrusion 222, and the fixing base 23 and the turntable 21 can be removed. After completion, the turntable can be reset.

[0022] Determine the optimal spacing between the two limiting rods based on the diameter of the container to be filled. This spacing should be slightly larger than the container diameter to provide both guidance and limiting, without causing the container to jam or generate excessive friction due to excessive tightness. When the adjusting screw 42 rotates, the two adjusting seats 43 that are engaged with the reverse threads will move inward or outward simultaneously along the screw axis, achieving synchronous opposite or backward movement. When the adjusting seats move, they will drive the connecting seat 44 that is rotatably connected to them to move together. The connecting seat 44 is fixedly connected to the limiting rod 41, so the limiting rod 41 will move with the connecting seat, thereby changing the parallel distance between the two limiting rods 41. After adjusting to the predetermined position, it can be placed in a container for testing to observe whether it can roll smoothly between the two limiting rods 41 without obvious shaking.

[0023] The operator presses down on the control lever 234 protruding from the top surface of the fixed base 23. The downward movement of the control lever 234 compresses the elastic element 235 sleeved on its outside. The bottom of the control lever 234 pushes the connector 233 downward. The connector 233 transmits force to the two opposing fixed hooks 231, forcing the elastic fixed hooks 231 to produce a slight elastic deformation inward (towards each other). This causes the hooking surface 232 at the front end of the fixing hook 231 to disengage from the mating surface 223 of the mating protrusion 222 on the mounting base 22. While holding the control lever 234 pressed, the entire fixing base 23 can be vertically removed from the mating cavity 221 of the mounting base 22. After the fixing base 23 is removed, the turntable 21, which was originally clamped between the fixing base 23 and the mounting base 22, is in a free state. At this time, the turntable 21 can be directly lifted off the mounting base 22 and removed. A new or cleaned turntable 21 is then placed on the mounting base 22, ensuring that the receiving groove 211 on the turntable 21 is aligned with the filling station. The fixing hook 231 below the fixing base 22 is aligned with the mating cavity 221 on the mounting base 22, and the fixing base 23 is vertically removed. Insert the hook 231 straight down into the fitting cavity 221. During insertion, the inclined surface of the fixing hook 231 will contact the inclined surface of the fitting protrusion 222. Even without pressing the control lever 234, the guiding effect of the inclined surface will force the fixing hook 231 to slightly contract and deform inward until the fixing hook 231 completely slides past the fitting protrusion 222. When the hooking surface 232 of the fixing hook 231 descends to a position lower than the fitting surface 223 of the fitting protrusion 222, the fixing hook 231 will quickly return to its original position due to its own elasticity, so that the hooking surface 232 firmly hooks the fitting surface 223. At this time, the rebound force of the elastic element 235 will push the control lever 234 back to its original position to complete the locking. The fixing seat 23 can be slightly lifted upward to confirm that it is firmly locked on the mounting seat 22.
