Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of needle-assisted nest-removal devices, and more specifically to a needle-assisted nest-removal device. Background Technology
[0002] Before being removed from their nests, syringes are densely packed into nesting plates (a type of plastic or metal support plate) to facilitate initial batch processing such as sterilization and cleaning. However, to complete final production, they must first be removed from their nests, as only after removal can the syringes proceed to subsequent processes such as labeling, printing, testing (e.g., sealing and visual inspection), and assembly (e.g., connecting push rods and needle hubs). These processes require syringes to enter the equipment individually and in an orderly manner, which is not suitable for the fixed batch state of the nesting plates. The syringe-assisted removal device is a specialized piece of equipment designed for pre-filled syringes, pre-filled syringes, and other products in the medical device manufacturing industry. Its core function is to efficiently and non-destructively separate and remove the sterilized syringes that are arrayed in the nesting plates (support plates), providing support for subsequent labeling, testing, and packaging processes.
[0003] For example, in the prior art disclosure CN216862087U, there is a needle-assisted detachment device. The curved shape of the recessed part is the same as the curved shape of the bottom of the needle. When the needle falls freely onto the lifting plate, it can better protect the bottom of the needle from damage. At the same time, the recessed part can restrict the movement of the needle in the plane perpendicular to the abutment, prevent the bottom of the needle from moving horizontally, and facilitate the removal of the needle.
[0004] However, the existing technology has the following problems when used: When performing the separation operation, the traditional syringe-assisted detachment device relies solely on a single bottom structure to apply separation force to the syringe. This design is prone to radial displacement of the syringe during its upward movement, causing structural damage to the syringe during the detachment stage and affecting the service life of the syringe. Utility Model Content
[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a needle-assisted nest removal device. A support frame holds the nest plate in place, and a limiting block restricts multiple needles on the nest plate. When an electric push rod drives a lifting plate to raise the multiple needles, the limiting holes on the limiting block continuously provide positioning, effectively preventing needle deviation and ensuring the stability and safety of the separation process. This avoids damage caused by needle shaking, thus solving the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a needle-assisted nest removal device, comprising a support frame, positioning grooves on both inner walls of the support frame, a nest plate containing multiple needles between two positioning grooves, a fixing plate fixedly attached to the front end of the nest plate, the fixing plate being detachably fixed to the support frame, a limiting block and a lifting plate inside the support frame, the limiting block and the lifting plate being respectively located above and below the nest plate, the limiting block having a limiting hole corresponding to the multiple needles at its top, the lifting plate having a groove corresponding to the multiple needles at its top, and a lifting assembly at the bottom of the lifting plate.
[0007] In a preferred embodiment, a rubber sleeve is fixedly provided inside each groove. The rubber sleeve is fitted over the outside of the needle tube and is soft in texture, which can play a buffering role between the needle tube and the groove.
[0008] In a preferred embodiment, a handle is fixedly provided at the front end of the fixing plate. The outer wall of the handle is processed with anti-slip texture. The handle makes it convenient for workers to quickly pull out the nesting board for replacement, and the anti-slip texture design can increase the anti-slip performance.
[0009] In a preferred embodiment, sliders are fixedly provided on both sides of the limiting block and both sides of the lifting plate, and grooves adapted to the sliders are opened on the inner walls of both sides of the support frame. The sliders are located in the grooves. By using the sliders and grooves in cooperation, the stability of the limiting block and the lifting plate during lifting can be further improved.
[0010] In a preferred embodiment, fastening bolts are threaded to the top of both sides of the support frame, and the fastening bolts are fixed to the slider on one side of the limiting block, which facilitates quick adjustment of the height of the limiting block.
[0011] In a preferred embodiment, the lifting assembly includes an electric push rod, which is fixedly embedded in the inner wall of the bottom of the support frame. A connecting plate is fixedly provided at the top of the piston rod of the electric push rod. A connecting groove is provided at the bottom of the lifting plate, and the connecting plate is fixed in the connecting groove. The electric push rod drives the lifting plate to automatically lift and lower, thereby improving the separation efficiency.
[0012] In a preferred embodiment, an emergency stop switch is fixedly provided on the inner wall of the bottom of the support frame. The emergency stop switch is located on one side of the electric push rod and is connected to the electric push rod through an electric wire. When an unexpected situation occurs (such as the electric push rod extending or retracting too quickly), the operator immediately presses the emergency stop switch to shut down the electric push rod, so as to avoid the rising speed being too fast and affecting the separation effect.
[0013] The technical effects and advantages of this utility model are as follows: This invention uses a support frame to hold the nest plate in place and a limiting block to limit the multiple needle tubes on the nest plate. When the lifting plate is driven by an electric push rod to raise the multiple needle tubes, the limiting holes on the limiting block can continuously play a positioning role, effectively preventing the needle tubes from deviating, ensuring the stability and safety of the separation process, and avoiding damage caused by needle tube shaking.

Detailed Implementation
[0016] 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.
[0017] Refer to the instruction manual appendix Figures 1-5 This utility model provides a needle-assisted nest removal device, including a support frame 1. The inner walls of both sides of the support frame 1 are provided with positioning grooves 2. A nest plate 3 containing multiple needles is provided between the two positioning grooves 2. A fixing plate 4 is fixedly provided at the front end of the nest plate 3. The fixing plate 4 is detachably fixed to the support frame 1. The support frame 1 is provided with a limiting block 5 and a lifting plate 6 inside. The limiting block 5 and the lifting plate 6 are respectively provided above and below the nest plate 3. The top of the limiting block 5 is provided with a limiting hole 7 corresponding to the multiple needles. The top of the lifting plate 6 is provided with a groove 8 corresponding to the multiple needles.
[0018] The bottom of the lifting plate 6 is provided with a lifting assembly 9, which includes an electric push rod 91. The electric push rod 91 is fixedly embedded in the bottom inner wall of the support frame 1. A connecting plate 92 is fixedly provided at the top of the piston rod of the electric push rod 91. A connecting groove 93 is opened at the bottom of the lifting plate 6, and the connecting plate 92 is fixed in the connecting groove 93. The electric push rod 91 can be a worm gear drive + trapezoidal screw type. The combination of "worm gear reduction + trapezoidal screw drive" achieves inherent self-locking without the need for an additional braking device, thereby improving the safety of use.
[0019] Slider blocks 12 are fixedly installed on both sides of the limiting block 5 and both sides of the lifting plate 6. Slide grooves 13 adapted to the sliders 12 are formed on the inner walls of both sides of the support frame 1. The sliders 12 are disposed within the slide grooves 13, and fastening bolts 14 are threadedly connected to the top of both sides of the support frame 1. The fastening bolts 14 are fixed to the slider 12 on one side of the limiting block 5. The cooperation between the sliders 12 and the slide grooves 13 further improves the stability of the limiting block 5 and the lifting plate 6 during lifting.
[0020] In actual operation, the staff first inserts the nest plate 3 between the two positioning slots 2 on the support frame 1, and uses bolts to fasten the fixing plate 4 to the support frame 1. Then, the limiting block 5 is pushed down and fixed by the fastening bolt 14, so that its bottom is in contact with the top of the nest plate 3. At this time, the tops of multiple needles are inserted into the corresponding limiting holes 7. Then, the electric push rod 91 is used to drive the lifting plate 6 to move upward, so that the bottoms of multiple needles on the nest plate 3 are inserted into the corresponding grooves 8. As the lifting plate 6 continues to rise, the needles are gradually separated from the nest plate 3 under the push of the lifting plate 6 and move upward smoothly. During this process, the limiting holes 7 continue to play a positioning role, effectively preventing the needles from deviating and ensuring the stability and safety of the separation process.
[0021] like Figure 2 As shown, a rubber sleeve 10 is fixedly installed inside each groove 8, and the rubber sleeve 10 is fitted over the outside of the needle tube. The rubber sleeve 10 is soft and can act as a buffer between the needle tube and the groove 8.
[0022] like Figure 1 and Figure 2 As shown, a handle 11 is fixedly provided at the front end of the fixing plate 4, and the outer wall of the handle 11 is processed with anti-slip texture. The handle 11 makes it convenient for workers to quickly pull out the nest plate 3 for replacement, and the anti-slip texture design can increase the anti-slip performance.
[0023] To improve the safety of the electric linear actuator 91, such as Figure 1 and Figure 2As shown, an emergency stop switch 15 is also fixedly installed on the inner wall of the bottom of the support frame 1. The emergency stop switch 15 is a safety control device used to quickly cut off the power supply to the equipment or stop its operation in an emergency. Its core function is to ensure the safety of personnel and equipment. The emergency stop switch 15 is located on one side of the electric push rod 91 and is connected to the electric push rod 91 through a wire. In case of an unexpected situation, such as the electric push rod 91 extending or retracting too quickly, the operator can immediately press the emergency stop switch 15 to shut down the electric push rod 91, preventing the excessively fast upward speed from affecting the separation effect.
[0024] Finally: 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.
