Description

Technical Field

[0001] This application relates to the field of medical device processing technology, and more specifically, to an assembly device and a needleless injector processing system. Background Technology

[0002] A needle-free injector is a syringe that uses the energy released by a spring to pressurize a liquid medication, causing the high-pressure liquid to pass through tiny orifices and form a high-speed jet. This jet penetrates the skin of a human or animal and enters the subcutaneous muscle tissue to complete the injection function. Needle-free injectors typically use steel balls to lock the syringe plunger. Currently, the assembly of these steel balls is mostly done manually by workers, which is inefficient. Utility Model Content

[0003] The purpose of this application is to address the shortcomings of the prior art by providing an assembly device and a needleless injector processing system that can improve the assembly efficiency of steel balls.

[0039] A needle-free injector is a syringe that uses the energy released by a spring to pressurize a medication, causing the high-pressure medication to pass through tiny orifices and form a high-speed jet. This jet penetrates the skin of a human or animal and enters the subcutaneous muscle tissue to complete the injection function. Please refer to [link / reference]. Figure 1Needle-free injectors typically use steel balls to lock the injector plunger, and these steel balls must be installed inside a carrier 30. Generally, the carrier 30 is a hollow cylinder with multiple equally spaced mounting holes 31 along its annular sidewall. Each mounting hole 31 requires the insertion of a steel ball. Currently, the insertion of the steel balls into the mounting holes 31 is mostly done manually by workers, which is inefficient.

[0040] To address the aforementioned technical problems, one aspect of the embodiments of this application is described in conjunction with reference to... Figure 2 An assembly apparatus 10 is provided, including a feeding mechanism 11, for replacing workers in sequentially loading multiple steel balls into multiple mounting holes 31 of a carrier 30.

[0041] Specifically, please refer to the following: Figures 2 to 4 The feeding mechanism 11 includes a base 111, a material distribution component 112 disposed on the base 111, and a discharge rod 113. The material distribution component 112 includes a material distribution slider 1122, which has a first channel 1122a. The material distribution slider 1122 has a material distribution station and a discharge station. When the material distribution slider 1122 is in the material distribution station, the first channel 1122a is connected to the discharge port of the hopper 20, and the steel balls in the hopper 20 enter the first channel 1122a. When the material distribution slider 1122 is in the discharge station, the two ends of the first channel 1122a are connected to the discharge rod 113 and the mounting hole 31 of the carrier 30, respectively, and the discharge rod 113 pushes the steel balls in the first channel 1122a into the mounting hole 31.

[0042] It should be noted that the material distribution slider 1122 can be directly mounted on the base 111, or it can be mounted on other parts on the base 111. The material distribution slider 1122 is movable relative to the base 111, thus having a material distribution station and a material discharge station. The material distribution slider 1122 can move by sliding, rotating, etc. The material distribution slider 1122 is provided with a first channel 1122a, the end of which protrudes from the material distribution slider 1122, so that the steel balls can smoothly enter and exit the first channel 1122a.

[0043] The material distribution slider 1122 has at least a material distribution station and a material discharge station, both located on the movement path of the material distribution slider 1122. When the material distribution slider 1122 is in the material distribution station, one end of the first channel 1122a is connected to the discharge port of the hopper 20, allowing steel balls in the hopper 20 to enter the first channel 1122a. At this time, the other end of the first channel 1122a is preferably closed, the method of closure is not limited, to prevent steel balls from falling out. Afterwards, the material distribution slider 1122 carries the steel balls to the material discharge station. When the material distribution slider 1122 is in the material discharge station, one end of the first channel 1122a is connected to the discharge rod 113, and the other end is connected to the mounting hole 31 of the carrier 30. The discharge rod 113 extends into the first channel 1122a, pushing the steel balls in the first channel 1122a into the mounting hole 31 of the carrier 30.

[0044] It is understood that each time the discharge rod 113 extends, it pushes a steel ball into the mounting hole 31 of the carrier 30. After the discharge rod 113 extends once, the carrier 30 or the feeding mechanism 11 rotates so that the other end of the first channel 1122a corresponds to the empty mounting hole 31, and the next steel ball is installed, until all the steel balls in the first channel 1122a are installed or the mounting holes 31 on the carrier 30 are completely filled.

[0045] Furthermore, the connection between the end of the first channel 1122a and the discharge port of the hopper 20, as mentioned above, means that the steel balls in the hopper 20 can enter the first channel 1122a through the discharge port after being driven. Similarly, the connection between the end of the first channel 1122a and the mounting hole 31 of the carrier 30 means that the steel balls in the first channel 1122a can enter the mounting hole 31 of the carrier 30 after being driven. As for the connection between the end of the first channel 1122a and the discharge rod 113, it means that the discharge rod 113 can extend into and out of the first channel 1122a, thereby pushing the steel balls in the first channel 1122a into the mounting hole 31 of the carrier 30. The two connected parts can be in direct contact or spaced apart and connected through other intermediate structures; this embodiment does not limit this.

[0046] The assembly device 10, by providing a movable material distribution slider 1122 on the base 111, distributes steel balls in the hopper 20 and transfers a certain number of separated steel balls between the discharge rod 113 and the carrier 30. Then, the extension and retraction of the discharge rod 113 pushes the steel balls sequentially into multiple mounting holes 31 in the carrier 30. This assembly device 10 enables automatic assembly of steel balls, thereby significantly improving the assembly efficiency.

[0047] Alternatively, please refer to Figure 1 and Figure 4The first channel 1122a is used to accommodate a preset number of steel balls, and the steel balls are arranged sequentially along the extension direction of the first channel 1122a. The preset number is equal to the number of mounting holes 31 on the carrier 30.

[0048] In this way, the number of steel balls separated by the material separating slider 1122 in a single operation is exactly equal to the number of mounting holes 31 on the carrier 30, ensuring the accuracy of the number of steel balls during material separation. The discharge rod 113 only needs to push all the steel balls in the material separating slider 1122 into the mounting holes 31 of the carrier 30 in sequence to complete the assembly of steel balls on one carrier 30.

[0049] The first channel 1122a preferably extends in a straight line to facilitate the discharge rod 113 pushing the steel balls into the mounting hole 31 of the carrier 30. The diameter of the first channel 1122a should be equal to or slightly larger than the diameter of the steel balls to ensure that the steel balls can be arranged sequentially within the first channel 1122a. For example, the diameter of the first channel 1122a is 1.05 to 1.3 times the diameter of the steel balls. This reduces friction between the steel balls and the inner wall of the first channel 1122a, facilitating discharge, and also ensures that multiple steel balls are arranged sequentially within the first channel 1122a.

[0050] When the first channel 1122a extends in a straight line, the discharge rod 113 should reciprocate in the same direction. Optionally, one end of the discharge rod 113 is used to extend into the first channel 1122a to push out the steel ball, and the other end is driven to connect with a drive unit 134 (such as a cylinder, electric push rod, linear module, etc.) that moves in a straight line at the output end.

[0051] Alternatively, please refer to Figures 2 to 5 The material distribution assembly 112 also includes a material distribution platform 1121, which is fixed on the base 111. A material distribution slider 1122 is movably disposed on the material distribution platform 1121 and can slide and rotate relative to it. The material distribution platform 1121 has a second channel 1121a, a third channel 1121b, and a fourth channel 1121c. The discharge rod 113 is disposed within the third channel 1121b. The ends of the second channel 1121a, the third channel 1121b, and the fourth channel 1121c are all exposed above the material distribution platform 1121. The second channel 1121a and the fourth channel 1121c are used for the transfer of steel balls, while the third channel 1121b is used to limit and guide the movement of the discharge rod 113.

[0052] Please refer to the reference. Figure 1 When the material distribution slider 1122 is in the material distribution position, one end of the second channel 1121a is connected to the discharge port of the hopper 20, and the other end is connected to the first channel 1122a. That is, the end of the first channel 1122a is connected to the discharge port of the hopper 20 through the second channel 1121a on the material distribution platform 1121.

[0053] When the material distribution slider 1122 is in the discharge position, the two ends of the first channel 1122a are respectively connected to the third channel 1121b and the fourth channel 1121c, and the other end of the fourth channel 1121c is connected to the mounting hole 31. That is, the end of the first channel 1122a is connected to the mounting hole 31 of the carrier 30 through the fourth channel 1121c.

[0054] The material distribution table 1121 can guide the movement of the material distribution slider 1122, making the movement of the material distribution slider 1122 more precise.

[0055] Optionally, when the material distribution slider 1122 is in the material distribution station, the ends of the first channel 1122a and the second channel 1121a are in contact; when the material distribution slider 1122 is in the discharge station, the two ends of the first channel 1122a are in contact with the ends of the third channel 1121b and the fourth channel 1121c, respectively. This allows for the smooth transfer of steel balls. When the material distribution slider 1122 is in the material distribution station, the other end of the first channel 1122a can also be sealed off by the side wall of the material distribution table 1121 to prevent steel balls from falling out.

[0056] Optionally, the second channel 1121a is connected to the discharge port of the hopper 20 by a pipe. That is, the first end of the pipe is connected to the discharge port of the hopper 20 and the second end is connected to the second channel 1121a. The first end of the pipe is higher than the second end, so that the steel ball can automatically enter the first channel 1122a.

[0057] Alternatively, please refer to Figures 3 to 5 The material distribution slider 1122 slides back and forth on the material distribution table 1121 along the first straight direction X. The first channel 1122a, the second channel 1121a, the third channel 1121b, and the fourth channel 1121c all extend along the second straight direction Y, which is perpendicular to the first straight direction X. Alternatively, please refer to... Figure 6 The material distribution slider 1122 reciprocates clockwise or counterclockwise on the material distribution table 1121, and the first channel 1122a, the second channel 1121a, the third channel 1121b and the fourth channel 1121c all extend radially along the material distribution slider 1122.

[0058] Both of the above methods can complete the distribution and transfer of steel balls in a relatively simple way. When the distribution slider 1122 moves along the first linear direction X, a drive component 134 with a linear motion output end, such as a cylinder, electric push rod, or linear module, can be used to drive the distribution slider 1122. When the distribution slider 1122 moves clockwise or counterclockwise, a drive component 134 with a rotational motion output end, such as a rotary motor, can be used to drive the distribution slider 1122.

[0059] Alternatively, please refer to Figure 1 and Figure 7 The assembly device 10 also includes a first positioning mechanism 12, which is used to position the carrier 30 to ensure the accuracy of the carrier 30's position. Specifically, the first positioning mechanism 12 includes a positioning rod 121 slidably disposed on the base 111, the head of which is used to insert into the positioning hole of the carrier 30 to position the carrier 30.

[0060] The positioning rod 121 can be driven by a drive member 134 whose output end moves linearly, such as a cylinder, electric push rod, or linear module. For example, the positioning rod 121 moves axially along the carrier 30, with its head inserted into a positioning hole in the carrier 30 from above. Alternatively, the positioning rod 121 moves radially along the carrier 30, with its head inserted into a positioning hole in the carrier 30 from the side.

[0061] Optionally, the first positioning mechanism 12 further includes a positioning block 122 that is slidably disposed on the base 111 along the third linear direction Z, a positioning rod 121 that is slidably disposed on the positioning block 122 along the third linear direction Z, and a spring 123 that is sleeved on the positioning rod 121, one end of the spring 123 abutting against the positioning block 122 and the other end abutting against the head of the positioning rod 121.

[0062] The positioning block 122 is slidable relative to the base 111, thereby causing the positioning rod 121 to move closer to or further away from the carrier 30. The positioning rod 121 is slidable relative to the positioning block 122, and both are in contact with the two ends of the spring 123, which allows the positioning rod 121 to be in a floating state. When the positioning rod 121 comes into contact with the carrier 30, the spring 123 acts as a buffer to prevent damage to the positioning rod 121 from rigid contact with the carrier 30.

[0063] During the steel ball assembly process, the carrier 30 needs to be rotated so that its multiple mounting holes 31 sequentially align and connect with the first channel 1122a. To further improve the steel ball assembly efficiency, optionally, please refer to... Figure 1 The assembly device 10 also includes a carrier switching mechanism 13, which is used to rotate the carrier 30. Specifically, the carrier switching mechanism 13 includes a carrier plate 132 rotatably mounted on the base 111. The carrier plate 132 has a positioning groove for placing and limiting the carrier 30. The center line of the positioning groove coincides with the rotation axis of the carrier plate 132. The carrier plate 132 rotates so that a plurality of mounting holes 31 on the carrier 30 are sequentially connected to the first channel 1122a.

[0064] It should be noted that the rotatable mounting of the carrier 132 on the base 111 means that the carrier 132 can rotate relative to the base 111, not that the carrier 132 is necessarily directly connected to the base 111. The carrier 132 has a positioning groove for placing the carrier 30 and limiting its movement. After the carrier 30 is placed in the positioning groove, the central axis of the carrier 30 coincides with the rotation axis of the carrier 132, and the mounting holes 31 on the carrier 30 protrude from the positioning groove. The carrier 132 drives the carrier 30 to rotate together, and the mounting holes 31 on the carrier 30 sequentially connect with the first channel 1122a. As the carrier 30 rotates, the steel balls in the first channel 1122a enter the mounting holes 31.

[0065] Optionally, the carrier disk 132 is coaxially connected to the output shaft of the carrier disk rotary motor 133 and rotates relative to the base 111 under the drive of the carrier disk rotary motor 133.

[0066] Optionally, the carrier switching mechanism 13 further includes a platform 131 rotatably mounted on the base 111, and a tray 132 rotatably mounted on the platform 131, with the axis of rotation of the tray 132 parallel to the axis of rotation of the platform 131. The rotation of the platform 131 can change the position of the tray 132, thereby placing the carrier 30 in different work positions (such as an assembly work position and a material unloading work position).

[0067] Optionally, please refer to the following: Figure 8 The vehicle switching mechanism 13 also includes:

[0068] The drive unit 134 has an output end that reciprocates along a fourth linear direction, which is perpendicular to the rotation axis of the platform 131. The drive unit 134 can be a cylinder, an electric actuator, a linear module, etc.

[0069] Rack 135 is fixedly connected to the output end of drive member 134 and reciprocates along the fourth straight line direction under the drive member 134. The extension direction of rack 135 is parallel to the fourth straight line direction. It should be noted that the extension direction of rack 135 refers to the sequential arrangement direction of the multiple teeth on rack 135.

[0070] Gear 136 meshes with rack 135, converting the linear motion of rack 135 into rotational motion.

[0071] A connecting shaft 137 is coaxially and fixedly connected to the gear 136, and is also fixedly connected to the platform 131. Thus, the rotational motion of the gear 136 can be transmitted to the platform 131 via the connecting shaft 137. It can be understood that the axis of the connecting shaft 137 coincides with the axis of rotation of the platform 131.

[0072] The stage 131 is driven to rotate by a combination of a drive component 134, a rack 135, and a gear 136, which can transmit large amounts of power and torque with high transmission accuracy and efficiency. In addition, it can save space in the direction perpendicular to the surface of the stage 131 (generally the vertical direction).

[0073] Optionally, the carrier switching mechanism 13 has a relative assembly station and a unloading station, and the number of carrier trays 132 is two. The two carrier trays 132 are symmetrically arranged about the rotation axis of the platform 131, and both carrier trays 132 can rotate and switch between the assembly station and the unloading station.

[0074] The platform 131 rotates, causing the carrier tray 132 on it to switch between the assembly station and the unloading station. At the assembly station, the platform 131 remains stationary, while the carrier tray 132 rotates around its own axis of rotation, cooperating with the discharge rod 113 to sequentially install multiple steel balls into the mounting holes 31. Afterward, the platform 131 rotates to transfer the carrier 30 filled with steel balls to the unloading station, where the unloading mechanism or a worker can remove the carrier 30.

[0075] The number of carrier trays 132 is equal to the number of workstations, and the carrier trays 132 are symmetrically arranged around the rotation axis of the stage 131. In this way, when one carrier tray 132 is in the assembly station, the other carrier tray 132 can be in the unloading station. A single rotation of the stage 131 can complete the switching of one carrier tray 132 from the assembly station to the unloading station, and the switching of another carrier tray 132 from the unloading station to the assembly station, further improving the assembly efficiency of steel balls.

[0076] Alternatively, please refer to Figure 1 The assembly device 10 also includes a vision inspection mechanism 14, which is used to take pictures of the mounting holes 31 into which the steel balls are inserted and transmit the pictures to the display terminal.

[0077] Staff can view photos of the vehicle 30 on the display terminal to determine whether steel balls have been inserted into the mounting holes 31 of the vehicle 30. If a steel ball is not successfully inserted into a mounting hole 31 of the vehicle 30, the vehicle switching mechanism 13 can be controlled to align the mounting hole 31 with the first channel 1122a again to install the steel ball.

[0078] Optionally, the vision inspection mechanism 14 is located on the side of the assembly station. After steel balls are inserted into the mounting holes 31 of the carrier 30, it is rotated at a preset angle to align with the camera 141 of the vision inspection mechanism 14.

[0079] By taking a picture of the mounting hole 31 after the steel ball has been inserted using camera 141, it is possible to detect in time whether the steel ball has been successfully inserted into the mounting hole 31. If the steel ball is not successfully inserted, the carrier 30 can be turned back in time to install the steel ball again.

[0080] Optionally, please refer to the following: Figure 7 The visual inspection agency 14 includes:

[0081] Camera 141 is used to take pictures of the mounting hole 31 into which the steel ball is inserted and to transmit the pictures to the display terminal.

[0082] The sensing element 142 is used to move synchronously with the discharge rod 113. The sensing element 142 can be directly disposed on the discharge rod 113, or it can be disposed on other structures that move synchronously with the discharge rod 113. For example, a connecting assembly 114 is provided between the discharge rod 113 and the driving member 134 that drives the discharge rod 113, and the sensing element 142 is disposed on the connecting assembly 114.

[0083] The sensor 143 and the controller are electrically connected to the sensor 143 and the camera 141 respectively. The sensor 143 is set on the movement path of the sensing element 142 and is used to send a command signal to the controller when the sensing element 142 passes by. The controller is used to control the camera 141 to take a picture after receiving the command signal.

[0084] The discharge rod 113 extends, and the sensing element 142 moves along with the discharge rod 113 and passes through the sensor 143. After the sensor 143 detects the movement of the sensing element 142, it determines that a steel ball has been loaded into the carrier 30 and sends a command signal to the controller. After receiving the command signal, the controller controls the camera 141 to take a picture of the mounting hole 31 where the steel ball was just loaded. The operator can determine whether the steel ball has been successfully installed based on the picture taken by the camera 141.

[0085] Alternatively, camera 141 is electrically connected to carrier disk rotation motor 133. Camera 141 takes one picture every time carrier disk rotation motor 133 rotates a preset angle. This preset angle depends on the number of mounting holes 31 on carrier 30. For example, if there are 5 mounting holes 31 on carrier 30, the preset angle is 72°, and camera 141 takes 5 pictures.

[0086] Generally speaking, please refer to Figure 1 and Figure 9 The mounting holes 31 of the carrier 30 are pre-applied with grease to hold the steel balls in place. However, to better prevent the steel balls from falling out during subsequent operation, the assembly device 10 may optionally include a cage distribution mechanism 15 and a material-retrieving and rotating mechanism 16. The cage distribution mechanism 15 is used to sequentially transfer multiple cages 40 to the unloading position, and the material-retrieving and rotating mechanism 16 is used to remove the cages 40 from the cage distribution mechanism 15 and place the cages 40 onto the carrier 30 to clamp and fix the steel balls between the cages 40 and the carrier 30, preventing the steel balls from falling out.

[0087] Optionally, the cage feeding mechanism 15 includes a feed channel 151 and a feeding cylinder. The feed channel 151 is used to store and transport the cage 40. The feeding cylinder is located above or below the feed channel 151. The push rod of the feeding cylinder can be inserted into the middle of the hole of the second cage 40 from the feeding position, thereby restricting the subsequent cage 40 and preventing it from moving to the feeding position.

[0088] The material handling and rotating mechanism 16 is used to remove the holder 40 closest to the unloading position from the feed channel 151 and then place it on the carrier 30. The material handling and rotating mechanism 16 includes a first finger gripper 161, a rotary cylinder for driving the first finger gripper 161 to rotate, a first slide cylinder 162 for driving the first finger gripper 161 to adjust its position in a linear direction, and a first gripper cylinder 163 for controlling the opening and closing of the first finger gripper 161.

[0089] The first slide cylinder 162 adjusts the position of the first finger clamp 161 in a straight line, so that the first finger clamp 161 moves to the outside of the retainer 40. The first gripper cylinder 163 controls the first finger clamp 161 to clamp the retainer 40. The rotary cylinder controls the first finger clamp 161 to rotate to the top of the carrier 30. Then, the first gripper cylinder 163 controls the first finger clamp 161 to release the retainer 40, thereby installing the retainer 40 on the carrier 30.

[0090] Optionally, the carrier switching mechanism 13 further includes a platform 131 rotatably mounted on the base 111. The platform 131 has an assembly station and a unloading station. When the platform 131 is in the assembly station, the discharge rod 113 pushes the steel ball into the mounting hole 31 of the carrier 30. When the platform 131 is in the unloading station, the material picking and rotating mechanism 16 sleeves the retainer 40 on the carrier 30.

[0091] By using the rotation of the platform 131, the assembly of steel balls and the installation of the retainer 40 can be carried out at different workstations, which can avoid interference between the mechanisms. It is also possible to install the retainer 40 on another platform 30 while steel balls are being assembled on one platform 30, thereby improving efficiency.

[0092] Optionally, the assembly device 10 further includes a second positioning mechanism 17, which is used to position the carrier 30 when the retainer 40 is fitted, so as to ensure the accuracy of the position of the carrier 30.

[0093] Optionally, the second positioning mechanism 17 includes a second finger clamp 171, a second slide cylinder 172 for driving the second finger clamp 171 to adjust its position in a straight line, and a second gripper cylinder 173 for controlling the opening and closing of the second finger clamp 171.

[0094] The second slide cylinder 172 adjusts the position of the second finger clamp 171 in a straight line, so that the second finger clamp 171 moves to the outside of the carrier 30, and the second gripper cylinder 173 controls the second finger clamp 171 to clamp the carrier 30, thereby achieving the positioning of the carrier 30.

[0095] Alternatively, please refer to Figure 2 and Figure 10 The assembly device 10 also includes a first material handling and transfer mechanism 18, which is used to place the empty carrier 30 on the carrier tray 132, thereby realizing the automatic transfer of the carrier 30.

[0096] Optionally, the assembly device 10 further includes a second material handling and transfer mechanism 19, which is used to remove the carrier 30 with the retainer 40 from the carrier tray 132, thereby realizing the automatic transfer of the carrier 30.

[0097] The first pick-and-place material transfer mechanism 18 and the second pick-and-place material transfer mechanism 19 can have the same structure. For example, both mechanisms include a third finger gripper 181, a first linear drive member 182 (such as a cylinder, electric push rod, linear module, etc.) that drives the third finger gripper 181 to adjust its position in the horizontal direction, a second linear drive member 183 that drives the third finger gripper 181 to adjust its position in the vertical direction, and a third gripper cylinder 184 that controls the opening and closing of the third finger gripper 181.

[0098] This embodiment also provides a needleless injector processing system, including the assembly device 10 as described above.

[0099] This needle-free injector processing system has the same structure and beneficial effects as the assembly device 10 in the foregoing embodiments. The structure and beneficial effects of the assembly device 10 have been described in detail in the foregoing embodiments and will not be repeated here.

[0100] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
