Description

Technical Field

[0001] This utility model relates to the field of condom detection technology, and in particular to a clip device and a sleeve-applying mechanism. Background Technology

[0002] In automated condom production lines, a clamping device is typically needed to open the condom's opening so it can be fitted onto a testing mold. In related technologies, the clamping device has multiple support claws, each driven by a corresponding cylinder. When compressed air enters the cylinder cavity, the high-pressure gas pushes a piston, causing the support claws to expand outwards, thus opening the condom's opening. However, when the support claws need to reset, this structure relies solely on passive venting from the cylinder cavity, resulting in a very slow and unstable reset speed. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a clamping device that can accelerate the reset speed of the support claw and improve the stability and reliability of the reset action.

[0004] This utility model also proposes an upper sleeve mechanism that includes the above-mentioned sleeve device.

[0005] According to a first aspect of the present invention, a clipping device includes: a mounting base, a plurality of support claws, and a plurality of cylinders. The mounting base defines a receiving groove for inserting a condom, the receiving groove being disposed around the condom, and the mounting base having an airflow channel inside. The plurality of support claws are spaced apart around the central axis of the receiving groove, and the plurality of support claws can pass through the opening of the condom together. The plurality of cylinders are correspondingly disposed with the plurality of support claws, and each cylinder has an inner cavity communicating with the airflow channel. A piston is slidably connected to the inner cavity, and each piston is connected to a corresponding support claw. An elastic element is disposed in the inner cavity, the elastic element being connected between the piston and the cylinder, and the elastic element being configured to drive the piston to move the corresponding support claw toward the central axis of the receiving groove when the airflow channel is vented.

[0006] The jacket device according to the embodiments of the present utility model has at least the following beneficial effects: The clamping device of this utility model adds an elastic element to the inner cavity of the cylinder and connects the elastic element between the piston and the cylinder. When the airflow channel drives the piston to expand the support claw to the condom through the intake air, the elastic element is compressed. When the airflow channel exhausts, the elastic element rebounds and generates a driving force, thereby driving the piston to move the corresponding support claw toward the central axis of the receiving groove. Through the synergistic effect of the driving force provided by the elastic element and the exhaust air, the exhaust resistance and friction of the inner cavity of the cylinder can be overcome, ensuring that the piston and support claw can quickly and accurately return to the initial position, thereby accelerating the reset speed of the support claw, improving the clamping efficiency, improving the stability and reliability of the reset action, and shortening the working cycle of the clamping device.

[0007] According to some embodiments of the present invention, the jacket device further includes a valve connected to the mounting base. The valve has a first port, a second port, and a third port. The first port is connected to a gas source, the second port is connected to the airflow channel, and the third port is connected to the external environment. The valve has a first state and a second state. When the valve is in the first state, the first port and the second port are connected, and the third port is closed. When the valve is in the second state, the second port and the third port are connected, and the first port is closed.

[0008] According to some embodiments of this utility model, the valve is provided with a valve core inside. When the valve is in the first state, the valve core can block the third port; when the valve is in the second state, the valve core can block the first port.

[0009] According to some embodiments of the present invention, the mounting base is constructed as an annular structure, the inner peripheral wall of the annular structure surrounds the receiving groove, the airflow channel extends circumferentially along the annular structure, and a plurality of cylinders are spaced apart around the outer periphery of the annular structure.

[0010] According to some embodiments of the present invention, the support claw includes a flared portion and a connecting portion. The flared portion extends axially along the annular structure. The mounting base is provided with a sliding groove penetrating its inner and outer peripheral walls. One end of the connecting portion is connected to the flared portion, and the other end passes through the sliding groove and is connected to the piston. The connecting portion is slidably connected to the sliding groove.

[0011] According to some embodiments of the present invention, the sidewall of the flared portion facing away from the central axis of the receiving groove is constructed as an arc surface, and the arc surface extends circumferentially along the receiving groove.

[0012] According to some embodiments of the present invention, the cylinder body and the connecting part are spaced apart along the axial direction of the annular structure, the piston is provided with a drive rod that extends out of the cylinder body from the receiving groove, and the jacket device further includes a connector, one end of which is connected to the connecting part, and the other end is bent to form a bent part connected to the drive rod.

[0013] According to a second aspect embodiment of the present invention, the upper sleeve mechanism includes a turntable, a drive mechanism, and a clamping device as described in the first aspect embodiment. When air enters through the airflow channel, the piston drives the corresponding support claw to move away from the central axis of the receiving groove to expand the opening of the condom. The turntable is provided with a column, and the drive mechanism is used to drive the clamping device to move toward the column so that the column passes through the opening into the condom.

[0014] The upper sleeve mechanism according to the embodiment of this utility model has at least the following beneficial effects: The upper sleeve mechanism of this utility model adopts the clamping device of the first aspect embodiment. By optimizing the structural design of the clamping device, it is ensured that the piston and the support claw can return to the initial position quickly and accurately, thereby accelerating the reset speed of the support claw, improving the stability and reliability of the reset action, shortening the working cycle of the clamping device, and thus reducing the time required for the upper sleeve action, improving the efficiency and stability of the upper sleeve.

[0015] According to some embodiments of this utility model, the column is inclined from bottom to top away from the central axis of the turntable. The driving mechanism includes a slide rail, a slider, a first driving device, and a second driving device. The clamping device is connected to the slider, and the slider is slidably connected to the slide rail. The first driving device is used to drive the slide rail to tilt so that the extension direction of the slide rail is consistent with the axial direction of the column. The second driving device is used to drive the slider to move the clamping device along the slide rail so as to put the safety condom into the column.

[0016] According to some embodiments of the present invention, the side wall of the mounting base is provided with a notch communicating with the receiving groove, the notch being used for the column to be moved out of the receiving groove.

[0023] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0024] In related technologies, the clamping devices of automated condom production lines generally employ a multi-cylinder driven claw structure. When the condom opening needs to be opened, compressed air enters the cylinder to push the piston, causing the claw to expand outward. However, during the reset phase, the cylinder cavity can only contract through passive exhaust, causing the claw reset speed to be affected by air pressure fluctuations, resulting in slow and asynchronous movements. For example, in high-speed production lines, slow reset movements can prolong the single operation cycle and reduce overall production efficiency.

[0025] To address the aforementioned problems, some embodiments of this utility model propose a clamping device 1000, suitable for the upper sleeve mechanism 3000, which can accelerate the reset speed of the support claw 200 and improve the stability and reliability of the reset action. See details below. Figures 1 to 6 The jacket device 1000 is described as shown.

[0026] Reference Figure 1 and Figure 2 As shown, in this embodiment of the present invention, the jacket device 1000 includes: a mounting base 100, multiple support claws 200, and multiple cylinders 300. The mounting base 100 is a support structure with an annular cavity, defining a receiving groove 110 for the condom 2000 to pass through. The receiving groove 110 surrounds the condom 2000. The mounting base 100 has an airflow channel 120 inside. The airflow channel 120's inlet end is connected to an external air source, and its outlet end is connected to each cylinder 300, ensuring that high-pressure gas can be evenly distributed to each cylinder 300. In this embodiment, the airflow channel 120 can be spiral or annular.

[0027] Continue to refer to Figure 1 and Figure 2 As shown, in this embodiment of the invention, the support claw 200 refers to a mechanical claw with an expansion function, which can be formed by stamping stainless steel sheet. Multiple support claws 200 are arranged radially around the central axis of the receiving groove 110, and can pass through the opening of the condom 2000 together, expanding the opening through synchronous movement. In this embodiment, multiple cylinders 300 are arranged in a one-to-one correspondence with multiple support claws 200.

[0028] Specifically, in this embodiment of the invention, the cylinder 300 refers to the pneumatic actuator, which can be a cylindrical aluminum alloy cylinder. (See reference...) Figure 2 As shown, each cylinder 300 has an internal cavity 310 communicating with the airflow channel 120. The diameter of the internal cavity 310 is in sliding fit with the piston 320. Each piston 320 is connected to a corresponding support claw 200 to drive the support claw 200 to move radially along the receiving groove 110. An elastic element 400, specifically a coil spring or a disc spring, is provided inside the internal cavity 310. The elastic element 400 is connected between the piston 320 and the cylinder 300. The elastic element 400 is configured to drive the piston 320 to move the corresponding support claw 200 toward the central axis of the receiving groove 110 when the airflow channel 120 exhausts air. In other words, the elastic element 400 provides a reverse driving force during the exhaust phase to ensure that the support claw 200 quickly returns to its original position.

[0029] Specifically, the airflow channel 120 inside the mounting base 100 controls the gas flow direction through an external air source. When the air source supplies air to the airflow channel 120, compressed air enters the inner cavity 310 of the cylinder 300, pushing the piston 320 to move outward against the resistance of the elastic element 400, causing the support claw 200 to expand outward and open the safety sleeve 2000. When the air source stops supplying air and starts exhausting, the air pressure in the inner cavity 310 of the cylinder 300 decreases, the elastic element 400 releases its stored energy, pushing the piston 320 to move in the opposite direction, causing the support claw 200 to quickly retract and return to its original position. During this process, the elastic element 400 and the air pressure form a bidirectional drive, ensuring that the support claw 200 receives active power in both the expansion and contraction phases.

[0030] It is understood that, compared with the technical solution that relies solely on air pressure to achieve reset, the clamping device 1000 of this utility model embodiment provides a mechanical active reset force during the exhaust phase through the synergistic effect of the elastic element 400 and the air pressure system, eliminating the influence of air pressure fluctuations on the reset speed. Simultaneously, the bidirectional movement of the support claw 200 is controlled by an active driving force, avoiding action delays caused by air pressure leakage and significantly improving action stability.

[0031] The clamping device 1000 of this utility model adds an elastic element 400 in the inner cavity 310 of the cylinder 300 and connects the elastic element 400 between the piston 320 and the cylinder 300. When the airflow channel 120 drives the piston 320 to drive the support claw 200 to widen the condom 2000 through the intake air, the elastic element 400 is compressed. When the airflow channel 120 exhausts air, the elastic element 400 rebounds and generates a driving force, thereby driving the piston 320 to move the corresponding support claw 200 toward the central axis of the receiving groove 110. Through the synergistic effect of the driving force provided by the elastic element 400 and the exhaust air, the exhaust resistance and friction of the inner cavity 310 of the cylinder 300 can be overcome, ensuring that the piston 320 and the support claw 200 can quickly and accurately return to the initial position, thereby accelerating the reset speed of the support claw 200, improving the stability and reliability of the reset action, shortening the working cycle of the clamping device 1000, and thus improving the operating efficiency of the entire automated production line.

[0032] Reference Figure 1 and Figure 3 As shown in this embodiment of the invention, the jacket device 1000 further includes a valve 500 connected to the mounting base 100. Specifically, the peripheral wall of the mounting base 100 has an air inlet 130 communicating with the internal airflow channel 120, and the valve 500 is installed at the air inlet 130. Specifically, the valve 500 is an actuator used to control the direction of gas flow, which can be implemented by using a solenoid valve or a mechanical directional valve, and achieves gas path switching by switching the conduction state of the port.

[0033] Reference Figure 3 As shown in this embodiment of the invention, valve 500 has a first port 510, a second port 520, and a third port 530. The first port 510 is connected to a gas source for introducing high-pressure gas. The second port 520 is connected to an airflow channel 120 for delivering gas to the inner cavity 310 of cylinder 300 or discharging it to the outside. The third port 530 is connected to the external environment for quickly releasing pressure in the inner cavity 310 of cylinder 300. Valve 500 has a first state and a second state. When valve 500 is in the first state, the first port 510 and the second port 520 are connected, and the third port 530 is closed. When valve 500 is in the second state, the second port 520 and the third port 530 are connected, and the first port 510 is closed.

[0034] Specifically, when the support claw 200 needs to expand outward, the valve 500 switches to the first state. At this time, the high-pressure gas from the gas source enters the airflow channel 120 through the first port 510 and the second port 520, and is then delivered to the inner cavity 310 of each cylinder 300. The high-pressure gas pushes the piston 320 to move outward against the resistance of the elastic element 400, causing the support claw 200 to move away from the central axis of the receiving groove 110 to open the opening of the condom 2000. When the support claw 200 needs to reset, the valve 500 switches to the second state. At this time, the second port 520 and the third port 530 are connected, and the gas in the inner cavity 310 of the cylinder 300 is quickly discharged to the external environment through the airflow channel 120. The elastic element 400 pushes the piston 320 to move the support claw 200 towards the central axis, achieving rapid reset.

[0035] It should be noted that when a reset is required, valve 500 switches states. At this time, the first port 510 closes, and the elastic element 400 begins to push the piston 320. During this process, the airflow passage 120 and the cylinder 300 are connected to the external environment. This means that the air in the cylinder 300 no longer needs to return along the original path, but can be discharged to the outside atmosphere nearby, directly and quickly through the valve 500 located on the mounting base 100.

[0036] It is understood that this embodiment provides an extremely short, high-flow exhaust path for the air in the inner cavity 310 of the cylinder 300, avoiding the significant fluid resistance and back pressure caused by the long backflow of air in the cylinder to the main control valve during reset. This ensures that the elastic element 400 is not subjected to the resistance of reverse air pressure when driving the piston 320 to reset, maximizing the reset efficiency of the elastic element 400 and further shortening the working cycle of the device.

[0037] Reference Figure 3 As shown in this embodiment of the invention, the valve 500 has a valve core 540 inside. When the valve 500 is in the first state, the valve core 540 can block the third port 530; when the valve 500 is in the second state, the valve core 540 can block the first port 510. The valve core 540 refers to a mechanical component disposed inside the valve 500 for switching the on / off state of the port. Specifically, it can be implemented using a rotary or sliding structure, such as a cylinder 710 or a slider 820 made of metal or plastic. Blocking the third port 530 means that the valve core 540 completely covers the inner opening of the third port 530 in the first state of the valve 500, preventing gas from leaking from the third port 530 to the external environment. Blocking the first port 510 means that the valve core 540 completely covers the inner opening of the first port 510 in the second state of the valve 500, blocking the connection between the gas source and the airflow channel 120.

[0038] Specifically, when valve 500 needs to switch to the first state, valve core 540 is moved to the third port 530 position by the air from the air source. At this time, the third port 530 is completely closed, and the first port 510 and the second port 520 form a communication path. Compressed air enters the airflow channel 120 from the air source through the first port 510, pushing piston 320 to move the support claw 200 outward. When valve 500 needs to switch to the second state, valve core 540 is moved to the first port 510 position by the air in the airflow channel 120. The first port 510 is completely closed, and the second port 520 and the third port 530 form a communication path. The gas in the airflow channel 120 is discharged through the third port 530, and elastic element 400 drives piston 320 to move the support claw 200 inward to reset.

[0039] Reference Figure 1 and Figure 2 As shown in this embodiment of the invention, the mounting base 100 is constructed as an annular structure, with an inner peripheral wall forming a receiving groove 110. The annular structure refers to the overall shape of the mounting base 100 being ring-shaped, and the receiving groove 110 formed on its inner peripheral wall guides the safety sleeve 2000 to axially insert and maintain stable alignment. The airflow channel 120 extends circumferentially along the annular structure, forming an annular channel for uniformly distributing airflow to the inner cavities 310 of each cylinder 300.

[0040] Reference Figure 2 As shown in this embodiment of the invention, multiple cylinders 300 are spaced apart around the outer periphery of the annular structure. In other words, multiple cylinders 300 are arranged in a circular array on the outside of the annular structure and installed using threaded connections or snap-fit ​​fixing methods, so that the inner cavities 310 of each cylinder 300 are connected through airflow channels 120, thereby synchronously controlling the movement of the support claws 200. Specifically, when the air source supplies or exhausts air, the airflow is quickly transmitted to the inner cavities 310 of each cylinder 300 through the circumferentially distributed airflow channels 120, pushing the piston 320 to drive the support claws 200 to move radially. The cylinders 300 are spaced apart around the outer periphery of the annular structure, so that the drive mechanisms 800 of each support claw 200 are evenly distributed in space, ensuring that the support claws 200 remain synchronized during expansion or contraction.

[0041] Reference Figure 1 and Figure 4As shown in the embodiment of this utility model, the support claw 200 includes a flared portion 210 and a connecting portion 220. The flared portion 210 refers to the expansion structure in the support claw 200 for contacting the opening of the condom 2000. The flared portion 210 extends axially along the annular structure, and its extension direction is consistent with the insertion direction of the condom 2000, which facilitates guiding the opening of the condom 2000 to expand. The mounting base 100 is provided with a groove 140 that penetrates its inner and outer peripheral walls. One end of the connecting portion 220 is connected to the flared portion 210, and the other end passes through the groove 140 and is connected to the piston 320. The connecting portion 220 is slidably connected to the groove 140.

[0042] Continue to refer to Figure 1 and Figure 4 As shown in this embodiment of the invention, the connecting part 220 is a transmission structure connecting the flared part 210 and the piston 320. Specifically, a rigid rod can pass through the slide groove 140 and be hinged to the piston 320, transmitting linear motion through a sliding connection. The slide groove 140 serves as a guide channel, and can specifically adopt a rectangular groove or a T-shaped groove structure to restrict the connecting part 220 to move only along a preset path, preventing the support claw 200 from deflecting.

[0043] Specifically, when the airflow channel 120 exhausts air, the elastic element 400 pushes the piston 320, causing the connecting part 220 to move along the slide groove 140 towards the central axis of the receiving groove 110. At this time, the flared part 210 contracts synchronously to release the condom 2000. When the airflow channel 120 intakes air, the air pressure drives the piston 320, causing the connecting part 220 to move along the slide groove 140 away from the central axis. The flared part 210 expands outward to open the condom 2000. The sliding fit between the slide groove 140 and the connecting part 220 forms a rigid guiding mechanism, ensuring that the multiple support claws 200 maintain synchronicity during movement and avoiding local tearing of the condom 2000 due to uneven force.

[0044] Reference Figure 1 and Figure 2 As shown in this embodiment of the invention, the sidewall of the flared portion 210 facing away from the central axis of the receiving groove 110 is constructed as an arc surface 211, which extends circumferentially along the receiving groove 110. The arc surface 211 is a continuously curved surface structure on the outer surface of the flared portion 210, specifically a circular arc or elliptical arc design. This arc surface 211 reduces stress concentration when in contact with the condom 2000, preventing sharp edges from scratching the material. The circumferential extension of the arc surface 211 means that the curved surface forms a complete annular transition surface around the axis of the receiving groove 110, ensuring that the support claw 200 has smooth contact characteristics at all circumferential positions.

[0045] Specifically, when the support claw 200 moves outward under the driving force, the arc surface 211 on the outer side of the flared portion 210 contacts the inner wall of the condom 2000. Since the arc surface 211 has no sharp edges or corners, the contact pressure is distributed over a larger contact area, preventing localized stress from exceeding the tensile strength of the condom 2000 material. Simultaneously, the continuous curved surface formed by the circumferential extension of the arc surface 211 ensures that all contact points maintain a uniform stress state during the opening of the condom 2000, further reducing the risk of material tearing.

[0046] Reference Figure 1 and Figure 4 As shown in this embodiment of the invention, the cylinder body 300 and the connecting portion 220 are spaced apart along the axial direction of the annular structure. The cylinder body 300 and the connecting portion 220 are spatially separated in the axial extension direction of the annular structure to avoid interference between them during movement. The piston 320 has a drive rod 330 extending out of the cylinder body 300 from the receiving groove 110. The drive rod 330 is a rod-shaped structure extending from the piston 320 to the outside of the cylinder body 300. Specifically, it can be implemented by integrally molding a metal rod with the piston 320, and is used to transmit the linear motion of the piston 320 to the outside.

[0047] Reference Figure 4 As shown in this embodiment of the invention, the clamping device 1000 further includes a connector 600. One end of the connector 600 is connected to the connecting portion 220, and the other end is bent to form a bent portion 610 connected to the drive rod 330. The bent portion 610 is a bent structure formed at the end of the connector 600. Specifically, the end of the connector 600 can be bent into an L-shape by stamping or welding to adapt to the axial direction of the drive rod 330 and realize the transmission of force in different directions of movement.

[0048] Specifically, when the airflow channel 120 exhausts air, the elastic element 400 pulls the piston 320 towards the central axis of the receiving groove 110. At this time, the drive rod 330 moves synchronously with the piston 320 and drives the connecting piece 600 to slide along the slide groove 140 through the bending part 610, causing the support claw 200 to retract inward. When the airflow channel 120 intakes air, the air pressure pushes the piston 320 to move in the opposite direction, and the drive rod 330 pulls the connecting piece 600 to slide outward through the bending part 610, causing the support claw 200 to expand outward. Since the cylinder body 300 and the connecting part 220 are axially spaced, the bending part 610 of the connecting piece 600 can compensate for the spatial misalignment between the drive rod 330 and the connecting part 220, ensuring the reliability of motion transmission.

[0049] Reference Figure 5 and Figure 6As shown, an embodiment of this utility model also proposes an upper sleeve mechanism 3000, including a turntable 700, a drive mechanism 800, and a sleeve device 1000 as described in the above embodiment. The turntable 700 is a rotating component carrying multiple columns 710, which can be implemented by welding a metal disc to the columns 710. When air enters through the airflow channel 120, the piston 320 drives the corresponding support claw 200 to move away from the central axis of the receiving groove 110, thereby expanding the opening of the condom 2000. The turntable 700 has columns 710, which serve as the sleeve carrier for the condom 2000 and have smooth surfaces. The drive mechanism 800 drives the sleeve device 1000 to move towards the columns 710, so that the columns 710 pass through the opening into the condom 2000. The drive mechanism 800 is the execution unit that controls the movement of the sleeve device 1000, which can be implemented by using a linear guide rail and a servo motor to ensure that the sleeve device 1000 moves along a predetermined path.

[0050] In this embodiment of the invention, the path of the column 710 penetrating the condom 2000 is the trajectory of the column 710 after the condom 2000 is expanded. Specifically, this is defined by the opening of the receiving groove 110, the gap of the support claw 200, and the opening of the condom 2000, ensuring unobstructed passage of the column 710. Specifically, when compressed air is input into the inner cavity 310 of the cylinder 300, the piston 320, under air pressure, drives the support claw 200 to move outward, causing the opening of the condom 2000 to expand uniformly. The drive mechanism 800 controls the clamping device 1000 to approach the turntable 700 along a predetermined trajectory. During this movement, the column 710 sequentially passes through the opening of the receiving groove 110, the gap of the support claw 200, and the opening of the condom 2000. The expanded state of the gap of the support claw 200 provides a contactless channel for the column 710, preventing friction between the surface of the column 710 and the support claw 200. After the condom is put on, the drive mechanism 800 drives the support claw 200 to move out of the condom 2000, the air source stops supplying air, the elastic element 400 drives the piston 320 to reset, causing the support claw 200 to retract and disengage from the condom 2000, and the drive mechanism 800 drives the clamping device 1000 back to the initial position.

[0051] The upper sleeve mechanism 3000 of this utility model adopts the clamping device 1000 of the above embodiment. By optimizing the structural design of the clamping device 1000, it is ensured that the piston 320 and the support claw 200 can return to the initial position quickly and accurately, thereby accelerating the reset speed of the support claw 200, improving the stability and reliability of the reset action, shortening the working cycle of the clamping device 1000, and thus reducing the time required for the upper sleeve action, improving the efficiency and stability of the upper sleeve.

[0052] Since the upper sleeve mechanism 3000 adopts all the technical solutions of the jacket device 1000 of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0053] Reference Figure 5 and Figure 6 As shown in this embodiment of the invention, the column 710 is inclined from bottom to top away from the central axis of the turntable 700, and the axis of the column 710 forms an acute angle with the axis of the turntable 700. Specifically, the column 710 can be inclinedly installed on the surface of the turntable 700 by welding or bolting. The drive mechanism 800 includes a slide rail 810, a slider 820, a first drive device 830, and a second drive device 840. The clamping device 1000 is connected to the slider 820, and the slider 820 is slidably connected to the slide rail 810. The first drive device 830 is used to drive the slide rail 810 to tilt so that the extension direction of the slide rail 810 is consistent with the axial direction of the column 710, that is, the extension axis of the slide rail 810 is parallel to the center line of the column 710. Specifically, the angle can be adjusted by driving the slide rail 810 to rotate around the axis by the first drive device 830. The second driving device 840 can specifically adopt a ball screw or gear and rack transmission mechanism. For example, the stepper motor of the second driving device 840 drives the screw to rotate, causing the slider 820 to move linearly along the slide rail 810. It is used to drive the slider 820 to move the clamping device 1000 along the slide rail 810 so as to put the condom 2000 into the column 710.

[0054] Specifically, after the condom 2000 is opened by the support claw 200 to form an expanded opening, the first driving device 830 first adjusts the tilt angle of the slide rail 810 so that its extension direction is completely aligned with the axis of the column 710. At this time, the second driving device 840 drives the slider 820 to move along the slide rail 810, driving the clamping device 1000 to move towards the column 710 as a whole, so that the expanded opening of the condom 2000 is accurately fitted into the tilted top of the column 710. Since the slide rail 810 and the column 710 are coaxial, the pushing path of the clamping device 1000 coincides with the axis of the column 710, avoiding the condom 2000 from deviating or getting stuck during the fitting process.

[0055] Reference Figure 1 and Figure 2 As shown in this embodiment of the invention, the side wall of the mounting base 100 is provided with a notch 150 communicating with the receiving groove 110. The notch 150 is used to allow the column 710 to move out of the receiving groove 110. The notch 150 is an opening structure on the side wall of the mounting base 100 that communicates with the receiving groove 110. Specifically, it can be implemented as a rectangular or arc-shaped slot, providing a path for the column 710 to detach and preventing structural interference between the column 710 and the mounting base 100.

[0056] Specifically, after the condom 2000 is opened by the support claw 200 and fitted onto the cylinder 710, the second drive device 840 controls the slider 820 to move the clamping device 1000 along the slide rail 810, causing the support claw 200 to disengage from the opening of the condom 2000. At this time, the first drive device 830 drives the slide rail 810 to rotate around its mounting point, causing the extension direction of the slide rail 810 to be offset from the tilt direction of the cylinder 710. The cylinder 710 rotates or translates with the turntable 700 and moves out of the receiving groove 110 through the notch 150 on the side wall of the mounting base 100. Thus, the condom 2000 remains fitted onto the cylinder 710, while the clamping device 1000 can quickly reset for the next operation.

[0057] In this embodiment of the invention, the upper sleeve mechanism 3000 is applied to a detection device for detecting condoms 2000. The detection device includes a sorting device 4000, a conveying device 5000, a flipping device, and the upper sleeve mechanism 3000 described above. The sorting device 4000 utilizes the torsional vibration of a vibrating plate and a spiral track to achieve automatic screening, orientation, and single-position output of bulk condoms 2000. Specifically, firstly, a batch of condoms 2000 to be sorted are fed into the hopper. After the device is started, an electromagnet on the base drives multiple sets of vibrating plates, causing the hopper to generate high-frequency torsional vibration around its vertical axis. Under the action of the vibration force, the condoms 2000 rise upwards along the spiral guide trough. During the rising process, a specific structure of the guide trough performs screening, causing the condoms 2000 to automatically adjust their posture. Ultimately, only condoms 2000 conforming to a uniform posture reach the upper outlet of the guide trough and are discharged via the first guide rail to the conveying device 5000.

[0058] The conveying device 5000 utilizes parallel differential conveying with dual synchronous belts to achieve automatic, fixed-distance opening and posture correction of the flexible condoms 2000. Specifically, a servo motor drives the first and second drive shafts via a transmission mechanism, thereby driving the two synchronous belts. The unloading end of the sorting device 4000 places the most rigid elastic band portion of the condom 2000 across the inner sides of the two synchronous belts. During the conveying process, the condoms 2000 are automatically opened to the fixed distance set by the two synchronous belts, maintaining a consistent opening posture. This achieves automatic queuing and equidistant output of the condoms 2000, facilitating gripping by the subsequent flipping device.

[0059] Understandably, when the conveyor 5000 outputs the condom 2000, the opening of the condom 2000 faces upwards. To facilitate the operation of the clamping device 1000, the flipping device can clamp the condom 2000 at the output end of the conveyor 5000 through two clamping members and rotate it 180° so that the opening of the condom 2000 faces downwards. At this time, the support claw 200 of the clamping device 1000 inserts into the opening and evenly expands the opening of the condom 2000. The turntable 700 of the upper fitting mechanism 3000 has a column 710 adapted to the condom 2000. After the clamping device 1000 pulls the expanded condom 2000 into the column 710, it is tested.

Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
