Technical Field

[0001] This utility model relates to the field of automated equipment technology for chemical synthesis, and more specifically, to a solid feeding relay device adapted to a robotic arm for chemical synthesis. Background Technology

[0002] In the field of chemical synthesis, automation and precision operation are crucial for improving production efficiency and ensuring product quality. Traditional solid raw material feeding methods often rely on manual operation, which is not only inefficient but also difficult to guarantee accuracy, especially when handling toxic, hazardous, or highly reactive chemicals, where manual operation also poses significant safety hazards. With technological advancements, robotic arm technology has been gradually introduced into the field of chemical synthesis to achieve automated operations. However, existing robotic arms often lack an efficient and precise relay device when handling solid material feeding, leading to instability in the feeding process and potentially affecting the effectiveness of chemical synthesis. Therefore, developing a solid material feeding relay device that can be used in conjunction with robotic arms has become an urgent problem to be solved in the field of chemical synthesis automation equipment technology.

[0014] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0015] like Figure 1-7 As shown in the embodiment of this utility model, a solid feeding relay device for a chemical synthesis adaptable robotic arm includes a housing 1. The housing 1 has a space in the middle for placing a feeding funnel 11. The housing 1 is symmetrically arranged on the left and right sides. The side of the housing 1 has two upper and lower sliding grooves. One of the sliding grooves has a clamping baffle 2 and the other sliding groove has a separation baffle 3. The clamping baffle 2 and the separation baffle 3 are slidably connected to the housing 1. Each of the clamping baffle 2 and the separation baffle 3 has a plurality of return springs 4 on the side facing the sliding groove. A vertical groove 5 is provided between the clamping baffle 2 and the separation baffle 3. An eccentric cam 6 is movably connected in the groove 5. The housing 1 has a clamping push rod 7 at the position of the eccentric cam 6. A spring 8 is sleeved on the clamping push rod 7. One end of the clamping push rod 7 has a clamping plate 16, and the other end of the clamping push rod 7 is connected to the eccentric cam 6. The clamping baffle 2 is provided with a clamping post 9, and the separation baffle 3 is provided with a separation post 10. The clamping post 9 and the separation post 10 can drive the eccentric cam 6 to rotate, thereby driving the two clamping push rods 7 to clamp and separate.

[0016] The upper and lower ends of the slide are provided with spring guide grooves 12. The upper and lower ends of the clamping baffle 2 and the separation baffle 3 are provided with sliders that cooperate with the spring guide grooves 12. The reset spring 4 is located in the spring guide groove 12. One end of the reset spring 4 is connected to the slider, and the other end of the reset spring 4 is connected to the outer shell 1.

[0017] When the eccentric cam 6 is driven to the clamping state by the clamping column 9, the cam part of the eccentric cam 6 drives the two clamping push rods 7 to act inward to clamp the feeding funnel 11; when the eccentric cam 6 is driven to the separation state by the separation column 10, the non-cam part of the eccentric cam 6 drives the two clamping push rods 7 to act outward to separate from the feeding funnel 11.

[0018] The groove 5 is provided with a fixed column 17, and the eccentric cam 6 is movably connected to the fixed column 17.

[0019] The feeding funnel 11 includes a feeding funnel body 14, which is detachably connected to a disposable funnel, and the bottom of the feeding funnel body 14 is connected to a plastic tube 15.

[0020] The inner wall of the feeding funnel 11 is coated with polytetrafluoroethylene.

[0021] Decorative covers 13 are provided at both ends of the slide, and the decorative covers 13 are fixedly connected to the outer shell 1 by bolts.

[0022] To facilitate understanding of the above-mentioned technical solutions of this utility model, the following detailed description of the above-mentioned technical solutions of this utility model is provided through specific usage methods.

[0023] In practical use, the solid feeding relay device for chemical synthesis adapted to a robotic arm according to this utility model includes a feeding funnel, a shell, a decorative cover, a clamping baffle, a separation baffle, a return spring, a clamping push rod, and an eccentric cam.

[0024] The decorative cover is made of nylon material, which has good wear resistance, corrosion resistance and lightweight properties. It can effectively protect the internal components of the device, prevent external dust and impurities from entering the device and affecting the operation of the components, and reduce the overall weight of the device, making it easy to install and transport. The decorative cover is fixed to the outer shell with bolts, which is easy to disassemble and facilitates the maintenance and repair of the internal components of the device in the future.

[0025] The main body of the feeding funnel is fixed inside the outer shell. A disposable funnel is detachably connected to its top, and a plastic tube for conveying solid powder is connected to its bottom. The top of the feeding funnel is the inlet, and the bottom is the outlet. The outlet is fixedly connected to the plastic tube, which is used to convey the solid powder in the feeding funnel to the next process. The inner wall of the feeding funnel is coated with polytetrafluoroethylene (PTFE). PTFE has an extremely low surface area, which can effectively reduce the adhesion of solid powder to the inner wall of the funnel, ensuring that the powder can fall smoothly, avoiding material blockage, and improving feeding efficiency.

[0026] The inner wall of the outer casing is provided with a sliding groove. Both the clamping baffle and the separating baffle are movably disposed in the sliding groove and can slide along the length of the sliding groove. One side of each clamping baffle and the separating baffle is provided with a spring guide groove for connecting a return spring. One end of the return spring is fixed in the spring guide groove, and the other end is fixed to the inner wall of the outer casing. Through the elastic force of the return spring, the clamping baffle and the separating baffle can automatically return to their initial positions when no external force is applied, ensuring the normal operation of the device. The clamping baffle is used to clamp and fix the disposable funnel when the robotic arm is gripping solid powder, preventing the disposable funnel from moving or falling off during the gripping process and ensuring the stability of the feeding. The separating baffle is used to separate the disposable funnel from the feeding funnel body after the robotic arm has finished gripping, making it easier for the robotic arm to transfer the gripped solid powder to the designated location.

[0027] The clamping push rod is located on the side wall of the housing, with one end extending into the housing and contacting the plastic tube, and the other end connected to an eccentric cam. When the robotic arm grabs the clamping baffle, the eccentric cam rotates, and its cam part pushes the clamping push rod inward, thereby pushing the clamping baffle to clamp the disposable funnel. When the robotic arm grabs the separation baffle, the eccentric cam continues to rotate until the non-cam part contacts the clamping push rod, at which point the clamping push rod moves outward under the action of the return spring, and the clamping baffle is released, thus realizing automated control of clamping and releasing.

[0028] The device has a compact overall structure and close cooperation between its components. Through the coordinated work of the robotic arm and the relay device, it can realize the automated and precise feeding of solid powders. It effectively solves the problems of serious material leakage, low feeding accuracy, complex structure and difficulty in cooperating with automated equipment in existing solid powder feeding devices, and improves the automation level and production efficiency of chemical synthesis process.

[0029] The work process is as follows: 1. Preliminary preparation: Connect the new disposable funnel to the annular buckle of the feeding funnel body through the slot, and remove the top sealing film; fix the device to the work position by installing the ear plate and positioning pin, ensuring that the disposable funnel, the feeding funnel body, and the plastic tube are coaxial.

[0030] 2. Feeding operation: Add solid powder (such as pharmaceutical powder or sterile flour) into the disposable funnel. The powder falls into the main body of the feeding funnel through the disposable funnel and then into the plastic tube. The robotic arm clamps the clamping baffle and drives it to slide along the slide groove. The rack and pinion drive the eccentric cam to rotate to the clamping position and push the clamping push rod to make the arc-shaped clamping block clamp the plastic tube, thus achieving sealed feeding (no leakage).

[0031] 3. Unloading operation: The robotic arm switches to the separation baffle and clamps, causing the separation baffle to slide. The rack and pinion drive gear to rotate the eccentric cam to the separation position. The spring drives the clamping push rod to reset, the plastic tube is released from clamping, and the powder falls along the plastic tube. After the powder in the disposable funnel is emptied, it can be directly removed and discarded without cleaning.

[0032] 4. Batch switching: When changing batches, simply remove the used disposable funnel, snap in the new disposable funnel, and you can proceed to the next batch operation, avoiding the waiting time of traditional funnel cleaning and drying (saving 40-60 minutes per batch).

[0033] In summary, by employing the synergistic effect of the eccentric cam driving the clamping push rod, combined with the sliding control of the clamping baffle and the separation baffle under the return spring, the feeding funnel can be clamped and released quickly and accurately, ensuring the stability and repeatability of the solid material feeding process, thereby achieving the goals of improving the efficiency of chemical synthesis production, ensuring product quality, and enhancing operational safety.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
