Description

Technical Field

[0001] This utility model relates to the field of condom testing technology, and in particular to a flipping device and a testing equipment for condoms. Background Technology

[0002] In related technologies, condom flipping devices typically include a mounting frame and a clamping assembly rotatably mounted on the frame. This clamping assembly requires compressed air to drive its clamping action, and components such as solenoid valves also require electrical signals for control. However, in current flipping devices, the air and power supply lines to the rotating clamping assembly are often externally connected to the mounting frame. When the clamping assembly performs the flipping action, these external wires and air pipes are highly susceptible to tangling and interference. Utility Model Content

[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] Currently, the air and power supply lines for the rotating clamping assembly in the flipping device are often connected from outside the fixed frame. When the clamping assembly performs the flipping action, these external wires and air pipes are prone to tangling and interference. This external wiring method not only affects the aesthetics of the equipment, but more importantly, it can lead to safety hazards such as pipe wear and breakage, seriously affecting the stability and service life of the equipment.

[0025] Furthermore, during high-speed flipping, the resistance generated by external pipelines can affect the flipping accuracy, causing the condom clamping position to shift, which in turn affects the accuracy of subsequent inspection processes. This interference problem is particularly pronounced in scenarios requiring multiple clamping components to work together, severely limiting the equipment's efficiency.

[0026] To address the aforementioned problems, some embodiments of this utility model propose a flipping device 1000, suitable for testing equipment used with condoms 2000. This device prevents the clamping assembly 300 from tangling or interfering with the tubing during flipping, reducing the risk of malfunctions caused by tubing tangling. See details below. Figures 1 to 6 The flipping device 1000 is described below.

[0027] Reference Figure 1 As shown, in this embodiment of the present invention, the flipping device 1000 includes: a fixing frame 100, a rotating slip ring 200, and a clamping assembly 300. The fixing frame 100 refers to the support structure that carries the stator portion 210 of the rotating slip ring 200, and can specifically be implemented using a metal frame or a mounting base plate. It is used to fix the static part of the entire device. Combined with... Figure 2 It is understood that in this embodiment, the rotary slip ring 200 includes a stator portion 210 and a rotor portion 220, which are mating components that enable relative rotation. The stator portion 210 can be fixed to the mounting bracket 100 by bolts, and the rotor portion 220 is rotatably connected to the stator portion 210 by bearings, and integrates both pneumatic and electrical transmission functions internally.

[0028] Reference Figure 2 and Figure 3As shown, in this embodiment of the invention, the stator section 210 is provided with a first air valve 211 and a first wire 212, and the rotor section 220 is provided with a second air valve 221 and a second wire 222. The rotating slip ring 200 is provided with airflow channels 230 that connect the first air valve 211 and the second air valve 221 respectively. The airflow channel 230 refers to the gas passage that runs through the stator section 210 and the rotor section 220. Specifically, it can adopt a concentric annular air passage or an axially penetrating pipe structure to ensure a continuous supply of air during rotation. In this embodiment, the rotating slip ring 200 is also provided with a conductive structure 240 that connects the first wire 212 and the second wire 222 respectively. This structure is an electrical passage connecting the wires of the stator section 210 and the rotor section 220, realizing power transmission during rotation.

[0029] Reference Figure 1 As shown in this embodiment of the invention, the clamping assembly 300 is connected to the rotor portion 220. The clamping assembly 300 includes a first cylinder 310 and two clamping members 320. The first cylinder 310 is connected to a second wire 222 and is also connected to a second air valve 221. It is understood that the second wire 222 is used to transmit a control electrical signal to the first cylinder 310. In response to the control signal, the first cylinder 310 can drive the two clamping members 320 to open and close, thereby driving the two clamping members 320 to clamp the condom 2000.

[0030] Understandably, since the condom 2000 is flexible, in one example, the clamping member 320 is provided with a brush portion to avoid damage to the condom 2000 during clamping. The condom 2000 itself is made of a thin material with a smooth surface, and it generates considerable inertia, especially during flipping movements. The numerous flexible bristles of the brush portion can contact and grip the condom 2000 from multiple angles, providing a more stable and reliable clamping force.

[0031] Secondly, rigid grippers, driven by cylinders, are difficult to precisely control in terms of clamping force. Excessive pressure or stress concentration can easily lead to products being crushed, scratched, or deformed irreversibly. Brushes, as a flexible contact medium, provide excellent cushioning, distributing the clamping force evenly across the contact surface. This ensures secure clamping while maximizing product protection from damage.

[0032] Specifically, the stator 210 remains stationary via the mounting bracket 100, while the clamping assembly 300 rotates synchronously with the rotor 220. When an external air source is connected to the first air valve 211 of the stator 210, the gas is transmitted through the airflow channel 230 of the rotating slip ring 200 to the second air valve 221 of the rotor 220, thereby driving the cylinder of the clamping assembly 300 to actuate. Simultaneously, external power is transmitted through the first wire 212 of the stator 210 and the conductive structure 240 to the second wire 222 of the rotor 220, providing a control signal to the solenoid valve of the first cylinder 310. After the clamping assembly 300 closes to clamp the safety sleeve 2000 under the drive of the first cylinder 310, the rotor 220 drives the clamping assembly 300 to rotate as a whole, completing the flipping operation of the safety sleeve 2000. Throughout the entire process, the air and electrical circuits are transmitted through the internal structure of the rotating slip ring 200, eliminating the need for external piping.

[0033] The flipping device 1000 of this utility model embodiment is provided with a rotating slip ring 200, wherein the rotating slip ring 200 includes a stator part 210 connected to the fixed frame 100 and a rotor part 220 connected to the clamping assembly 300. By providing a conductive structure 240 and an airflow channel 230 in the rotating slip ring 200, the electrical signals and compressed air required by the clamping assembly 300 can be transmitted from the stator part 210 to the rotor part 220, avoiding the bridging of external pipelines. This ensures that the clamping assembly 300 will not cause pipeline entanglement or interference when flipping. This not only makes the structure of the flipping device 1000 more compact and improves its operational stability and reliability, but also reduces the risk of failure caused by pipeline entanglement. It is especially suitable for automated production lines that require high speed and continuous flipping.

[0034] Reference Figure 3 As shown in the embodiment of this utility model, the airflow channel 230 includes a first channel 231 and a second channel 232. One end of the first channel 231 is connected to the second air valve 221, and the other end passes through and protrudes from the rotating slip ring 200 along its axial direction. Specifically, the first channel 231 is a pipe structure for guiding the airflow of the second air valve 221 along the axial direction of the rotating slip ring 200. It can be implemented using a metal pipe or a pressure-resistant plastic pipe. Its design of passing through the rotating slip ring 200 and extending outward can prevent the air passage from bending or breaking during rotation.

[0035] Continue to refer to Figure 3 As shown, in this embodiment of the present invention, one end of the second channel 232 is rotatably connected to the end of the first channel 231 away from the second air valve 221, and the other end is connected to the first air valve 211. The second channel 232 is a pipe structure used to redirect the airflow from the first channel 231 and deliver it to the first air valve 211. Specifically, it can be implemented using a bent pipe or a branch pipe. Its connection with the first channel 231 forms an airflow redirection node, ensuring the continuity of the airflow path.

[0036] To maintain airtightness, refer to Figure 3 As shown in the embodiment of this utility model, a sealing element 233 is provided at the connection between the first channel 231 and the second channel 232. It is an annular structure used to prevent gas leakage at the connection between the first channel 231 and the second channel 232. Specifically, it can be implemented by using a rubber ring or a polytetrafluoroethylene gasket.

[0037] Specifically, the first channel 231 extends from the second air valve 221 to the end of the rotary slip ring 200, and the second channel 232 extends in the opposite direction from the end of the first channel 231 to the first air valve 211. The seal 233 closes the gap at the connection to prevent gas leakage when the rotary slip ring 200 operates. By providing two separate channels, a continuous air path is formed inside the rotary slip ring 200, avoiding the risk of entanglement of external cross-connecting pipes. Simultaneously, the seal 233 ensures the stability of the air path during dynamic rotation.

[0038] Reference Figure 3 As shown, in this embodiment of the present invention, the conductive structure 240 includes a conductive ring 241 and a brush 242. The conductive ring 241 is disposed within the rotor portion 220 and connected to the second wire 222. The conductive ring 241 is an annular conductor disposed inside the rotor portion 220, specifically a copper alloy ring structure. Its inner diameter matches the mounting position of the rotor portion 220, and its surface is polished to reduce contact resistance. The brush 242 is disposed within the stator portion 210 and connected to the first wire 212. The brush 242 is slidably connected to the conductive ring 241. It is understood that the brush 242 is an elastic conductive component in contact with the conductive ring 241, specifically a carbon brush or a metal spring structure. It maintains continuous contact pressure with the conductive ring 241 through a spring mechanism, ensuring the continuity of current transmission during rotation.

[0039] Specifically, the conductive ring 241 rotates synchronously with the rotor section 220, while the brush 242 remains stationary in the stator section 210. When the rotor section 220 drives the clamping assembly 300 to rotate, a dynamic sliding contact is formed between the conductive ring 241 and the brush 242, creating a closed circuit between the first wire 212 and the second wire 222. The annular structure design of the conductive ring 241 ensures that its circumferential contact surface covers a 360° range, and the elastic contact method of the brush 242 can automatically compensate for the axial displacement generated during rotation, thereby maintaining a stable electrical connection at any rotation angle.

[0040] Reference Figure 1As shown in this embodiment of the invention, the flipping device 1000 further includes a second cylinder 400, which is connected to the clamping assembly 300 and communicates with the second air valve 221 to drive the clamping assembly 300 to move along a first direction. The stroke of the second cylinder 400 achieves precise positioning of the clamping assembly 300. Specifically, the second cylinder 400 uses compressed air to drive the piston rod to reciprocate, thereby moving the clamping assembly 300. It should be noted that the axial direction of the rotating slip ring 200 is set along the second direction; in other words, the clamping assembly 300 rotates around the second direction, while the first direction is the tangential direction of the rotation path of the clamping assembly 300.

[0041] Specifically, the second cylinder 400 is connected to the first valve 211 of the stator section 210 via the second valve 221 inside the rotary slip ring 200. Compressed air enters the airflow channel 230 from the outside through the first valve 211, and is then transmitted to the second cylinder 400 through the second valve 221. When the second valve 221 is open, the compressed air drives the piston rod of the second cylinder 400 to extend or retract, thereby moving the clamping assembly 300 along the first direction. Since the air path and electrical control signal of the second cylinder 400 are transmitted through the inside of the rotary slip ring 200, there is no need to arrange air pipes and wires outside the fixed frame 100, thus avoiding the tangling of pipelines when the clamping assembly 300 moves.

[0042] In this embodiment of the invention, compressed air can be supplied to both the first cylinder 310 and the second cylinder 400 using a single air source. It should be noted that, in one example, both the first cylinder 310 and the second cylinder 400 are equipped with quick-release valves, which can quickly discharge the compressed air from the cylinders into the external environment, thereby achieving rapid reset of both cylinders. In another example, both the first cylinder 310 and the second cylinder 400 are internally equipped with elastic elements, such as springs, for reset.

[0043] Reference Figure 1 As shown, in this embodiment of the invention, the flipping device 1000 further includes a connecting plate 500, with the rotor portion 220 fixedly connected to the connecting plate 500. A clamping assembly 300 is mounted on the connecting plate 500 and is radially spaced from the rotor portion 220 along the rotating slip ring 200. The connecting plate 500 serves as a transition structure between the clamping assembly 300 and the rotor portion 220 of the rotating slip ring 200. Specifically, it can be made of sheet metal and rigidly connected to the rotor portion 220 by bolts or welding. It is understood that the connecting plate 500 extends radially along the rotating slip ring 200, and the clamping assembly 300 can be connected to its end, thereby maintaining a predetermined distance between the clamping assembly 300 and the rotation axis of the rotating slip ring 200, avoiding mechanical interference caused by direct contact between the two.

[0044] Specifically, the connecting plate 500, as an independent load-bearing structure, separates the clamping assembly 300 from the rotor portion 220 of the rotary slip ring 200. When the rotary slip ring 200 drives the connecting plate 500 to rotate around its axis, the clamping assembly 300 rotates synchronously with the connecting plate 500 but maintains a radial offset from the rotor portion 220. This arrangement allows the air and electrical interfaces of the clamping assembly 300 to maintain a stable connection with the rotary slip ring 200 through the wiring grooves inside the connecting plate 500, while preventing the centrifugal force generated by the rotation of the clamping assembly 300 itself from directly acting on the precision components of the rotary slip ring 200.

[0045] Maintenance Reference Figure 1 As shown in this embodiment of the invention, the flipping device 1000 further includes a mounting plate 600, a motor 610, and a rotating shaft 620. The mounting plate 600 is a plate-like structure used to fix the motor 610 and provide support; it can be made of sheet metal. The mounting plate 600 and the connecting plate 500 are spaced apart along the axial direction of the rotating slip ring 200 to avoid interference with the connecting plate 500 during rotation. The motor 610 is mounted on the mounting plate 600, and one end of the rotating shaft 620 is connected to the motor 610, while the other end is connected to the connecting plate 500.

[0046] It is understood that in this embodiment of the present invention, the motor 610 is the power source for driving the rotation of the rotating shaft 620. Specifically, a servo motor 610 or a stepper motor 610 can be used. The starting, stopping, and speed of the motor 610 are controlled to achieve the flipping action of the clamping assembly 300. The rotating shaft 620 serves as a rigid rod for transmitting the torque of the motor 610. Specifically, it can adopt a combination structure of a stainless steel shaft and a coupling. One end of the shaft is connected to the output shaft of the motor 610, and the other end is fixed to the connecting plate 500 to achieve power transmission.

[0047] In this embodiment of the invention, the mounting plate 600 and the connecting plate 500 are spaced apart along the axial direction of the rotating slip ring 200, forming an independent mounting space. The motor 610, fixed to the mounting plate 600, drives the connecting plate 500 to rotate via the rotating shaft 620. When the motor 610 starts, the rotating shaft 620 transmits torque to the connecting plate 500, causing the clamping assembly 300 to rotate around the axis of the rotating slip ring 200. The spaced arrangement of the mounting plates 600 creates a physical isolation between the motor 610 and the rotating slip ring 200, preventing contact between the pipeline and the moving parts during rotation.

[0048] Reference Figure 1 and Figure 4As shown in this embodiment of the invention, the clamping assembly 300 is provided in two sets, which are symmetrically arranged around the center of the rotating slip ring 200. Specifically, the two sets of clamping assemblies 300 refer to two independent pneumatic clamping units, each unit including a first cylinder 310, a second cylinder 400 and two clamping members 320, which are used to perform clamping actions on two condoms 2000 simultaneously.

[0049] Specifically, the two sets of clamping assemblies 300 are fixed to the rotor portion 220 of the rotating slip ring 200 via connecting plates 500, and rotate synchronously around the axis under the drive of the rotating slip ring 200. Because the two sets of clamping assemblies 300 are centrally symmetrically arranged, the inertial forces generated during high-speed rotation cancel each other out, avoiding vibration problems caused by unilateral loads. By symmetrically arranging the two sets of clamping assemblies 300, while maintaining the advantage of no entanglement in the original gas and power supply lines, a single flipping action can simultaneously process two condoms 2000, improving efficiency.

[0050] Reference Figure 1 and Figure 2 As shown in this embodiment of the invention, multiple first wires 212 and multiple second wires 222 are provided. The multiple first wires 212 are spaced apart circumferentially along the stator portion 210, and the multiple second wires 222 are spaced apart circumferentially along the rotor portion 220. The first wires 212 are conductors in the stator portion 210 used for transmitting electrical signals, and the second wires 222 are conductors in the rotor portion 220 that are electrically connected to the first wires 212. When the rotating slip ring 200 is working, the multiple first wires 212 of the stator portion 210 and the multiple second wires 222 of the rotor portion 220 form dynamic contact through the conductive structure 240.

[0051] An embodiment of this utility model also proposes a testing device for a condom 2000, including the flipping device 1000 described in the above embodiment.

[0052] The detection device for condom 2000 in this embodiment of the present invention adopts the flipping device 1000 of the above embodiment. By optimizing the structural design of the flipping device 1000, the problem of mutual entanglement and interference between the wire and the air tube when the clamping component 300 is flipped is solved, thereby reducing the downtime of the detection device due to failure, enabling the detection device to operate stably for a long time and at a high frequency, improving the operational reliability of the detection device, and reducing maintenance costs and downtime.

[0053] Since the testing equipment for the condom 2000 adopts all the technical solutions of the flipping 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.

[0054] Reference Figure 4As shown in the present invention embodiment, the detection device further includes a conveying device 3000 disposed on one side of the flipping device 1000. The conveying device 3000 includes a first synchronous belt 3100 and a second synchronous belt. The first synchronous belt 3100 and the second synchronous belt are configured to jointly support the opening 2100 of the condom 2000, and to open the opening 2110 of the opening 2100 during the conveying of the condom 2000. The clamping component 300 is used to clamp the condom 2000 whose opening 2110 has been opened.

[0055] The conveying device 3000 refers to the mechanism used to transport the condom 2000 to the clamping station. Specifically, it can be achieved by the coordinated movement of two synchronous belts. During the conveying process, the synchronous belts pull open the opening 2110 of the condom 2000 through friction, providing a positioning basis for subsequent clamping and flipping. The first synchronous belt 3100 and the second synchronous belt refer to two parallel conveyor belts, which can be made of rubber or polyurethane material. A gap is formed between the two to accommodate the edge of the opening 2100 of the condom 2000. The opening 2110 is pulled open by the synchronous movement.

[0056] It is understood that in this embodiment of the invention, two synchronous belts support both sides of the opening 2100 of the condom 2000 in a clamping manner. Specifically, the spacing of the synchronous belts can be adjusted to match the size of the opening 2100 of the condom 2000, thereby maintaining the stability of the opening 2100 during transport. During transport, the difference in the direction of movement or speed of the synchronous belts is used to apply a lateral separation force to the opening 2100 of the condom 2000. Specifically, the friction can be increased by setting a texture on the surface of the synchronous belts, so that the opening 2100 gradually unfolds during movement.

[0057] Specifically, the testing equipment uses the first and second synchronous belts of the conveying device 3000 to support and open the opening 2100 of the condom 2000. Then, the clamping assembly 300 of the flipping device 1000 moves to the opening 2110 position. The first cylinder 310 drives the clamping member 320 to clamp the edge of the opened opening 2110. The rotor 220 of the rotating slip ring 200 drives the clamping assembly 300 to rotate, thus flipping the condom 2000. During this process, the airflow channel 230 and conductive structure 240 between the stator 210 and the rotor 220 continuously provide air and power to the clamping assembly 300, eliminating the need for external jumper pipes and avoiding pipeline interference caused by the rotation.

[0058] The condom 2000 is placed between the first synchronous belt 3100 and the second synchronous belt, with the edge of the opening 2100 embedded in the gap formed by the two synchronous belts. When the synchronous belts start, both move at the same speed along the conveying direction, driving the condom 2000 towards the clamping assembly 300. During this process, the frictional force generated by the synchronous belts on the edge of the opening 2100 causes the opening 2100 to be gradually stretched laterally until the opening 2110 is fully opened. At this time, the clamping assembly 300 moves to the end of the synchronous belt and drives the clamping member 320 to clamp the edge of the opened opening 2110 through the first cylinder 310, completing the preparation for gripping the condom 2000.

[0059] Combination Figure 5 and Figure 6 It is understood that in this embodiment of the invention, the detection equipment includes a sorting device 4000, a conveying device 3000, a flipping device 1000, and the sleeve-up device described in the above embodiment. The sorting device 4000 utilizes the torsional vibration of a vibrating plate and a spiral track to achieve automatic screening, orientation, and single-posture output of bulk condoms 2000. Specifically, firstly, the condoms 2000 to be sorted are batched into the hopper. After the device is started, the 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 vibration, the condoms 2000 rise upwards along the spiral guide chute. During the rising process, the specific structure of the guide chute performs screening, causing the condoms 2000 to automatically adjust their posture. Ultimately, only condoms 2000 that meet the uniform posture can reach the upper outlet of the guide chute and be discharged via the first guide rail to the conveying device 3000.

[0060] The conveying device 3000 utilizes parallel differential conveying with dual synchronous belts to achieve automatic, fixed-distance opening and posture correction of the flexible condom 2000. Specifically, the servo motor 610 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 of the synchronous belts towards the front end, the condom 2000 is automatically opened to the fixed distance set by the two synchronous belts, maintaining a consistent posture of the opening 2110. This achieves automatic queuing and equidistant output of the condoms 2000, providing convenient conditions for the subsequent gripping by the flipping device 1000.

[0061] Understandably, when the conveying device 3000 outputs the condom 2000, the opening 2110 of the condom 2000 faces upwards. To facilitate the operation of the clamping device 700, the flipping device 1000 can clamp the condom 2000 at the output end of the conveying device 3000 through two clamping members 320 and rotate it 180° so that the opening 2110 of the condom 2000 faces downwards. At this time, the support claw 710 of the clamping device 700 inserts into the opening 2110, and the drive cylinder 720 drives the support claw 710 to evenly expand the opening 2110 of the condom 2000. The turntable 5100 of the upper sleeve mechanism 5000 has a column adapted to the condom 2000. After the clamping device 700 pulls the expanded condom 2000 into the column, it is tested.

All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
