Description

Technical Field

[0001] The utility model relates to the technical field of condom detection mechanisms, in particular to a condom high-voltage pinhole detection mechanism. Background Art

[0002] With increasing awareness of contraception among modern people, the demand for condoms is increasing, and condom-related equipment is proliferating. A commonly used device for condom hole detection on the market is a semi-automatic device. This device consists of a mold loading tray, a mold charging and rotating assembly, a conductive rubber detection rotating assembly, an OK / NG unloading assembly, a manual loading station, an electrical cabinet, and an operating button box. This device works by manually loading the product into the inspection mold. Once the mold is in place, a motor drives the mold to rotate, while simultaneously driving the conductive rubber detection rotating assembly. During this relative rotation, the product on the mold makes contact with the conductive rubber multiple times, allowing for inspection. This device has certain drawbacks: the mold must remain stationary during inspection, allowing the conductive rubber to rotate and contact the product surface. This approach is inefficient in assembly line production. Furthermore, the design requires multiple motors to drive the movement of the mold, the rotation of the mold, and the rotation of the conductive rubber, resulting in high production costs. Utility Model Content

This mechanism utilizes a friction-conducting assembly to drive the detection mold rod, causing it to rotate and pass through the conductive assembly, achieving high-voltage pinhole detection. This reduces the use of motors and significantly reduces the production cost of the device.

DETAILED DESCRIPTION

[0019] The accompanying drawings are for illustrative purposes only and are not to be construed as limitations on this patent. To better illustrate this embodiment, some components of the accompanying drawings may be omitted, enlarged, or reduced in size, and do not represent the actual dimensions of the product. For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted from the accompanying drawings.

[0020] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installation" and "connection" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium, which can be considered as internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model. The technical solution of this utility model is further described below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1-Figure 5As shown, a high-voltage pinhole detection mechanism for condoms of the present invention includes a guide rail 1, to which a slide assembly 2 is slidably connected. The slide assembly 2 is driven to reciprocate linearly along the guide rail 1 by a drive assembly 3. A plurality of detection mold rods 6 are arranged on the slide assembly 2. The detection mold rods 6 are adapted to the condom products and can each rotate along their axial direction. A high-voltage detection structure adapted to the detection mold rods 6 is also provided on the guide rail 1. The high-voltage detection structure includes a friction conductive assembly 4 and a detection conductive assembly 5. The friction conductive assembly 4 is correspondingly located at the lower end of the detection mold rod 6 and causes the detection mold rod 6 to rotate. The detection conductive assembly 5 is located at the upper half of the detection mold rod 6 and releases voltage to the detection mold rod 6. During testing, the present invention eliminates the need for the detection mold rod 6 to remain in a fixed position; testing can be performed while in motion, resulting in a fast cycle and high production efficiency. A motor is also not required to drive the detection mold rod 6 in rotation. Since the detection mold rod 6 itself requires the drive assembly 3 to move it linearly, the friction conductive assembly 4 rubs the lower end of the detection mold rod 6 along its motion path. This friction force then ensures the detection mold rod's rotation, allowing it to roll relative to the detection conductive assembly 5, reducing equipment costs. This also eliminates the need for the detection conductive assembly 5 to rotate, requiring only a fixed position and voltage release, further reducing the need for a motor and lowering equipment costs. The friction conductive assembly 4 also receives changes in the voltage signal to determine whether the subsequent process should be unloaded, thereby achieving high-voltage pinhole detection.

[0022] In one embodiment, the friction conductive assembly 4 includes a first mounting plate 41, on which an insulating plate 42 is mounted. The insulating plate 42 is further provided with a baffle 43, a conductive rubber sheet 44, and a clamping sheet 45. The conductive rubber sheet 44 is secured to the insulating plate 42 by the baffle 43 and the clamping sheet 45. When the detection mold rod 6 passes through the friction conductive assembly 4, the conductive rubber sheet 44 abuts against the lower end of the detection mold rod 6. In addition to utilizing the conductive rubber sheet 44 to abut against the passing detection mold rod 6, ensuring that it rolls and rotates on the detection conductive assembly 5 through friction, the friction conductive assembly 4 also receives electrical signal feedback. Therefore, the baffle 43 and the clamping sheet 45 are used on the insulating plate 42 to prevent the detection mold rod 6 from falling under stress, thereby achieving the aforementioned effect. Furthermore, an annular groove is formed at the lower end of the detection mold rod 6 to accommodate the conductive rubber sheet 44. The length of the conductive rubber sheet 44 is greater than the circumference of the annular groove. In order to facilitate the conductive rubber sheet 44 to generate sufficient friction on the detection mold rod 6 and thus cause the detection mold rod 6 to rotate, the annular groove is set so that the conductive rubber sheet 44 protruding from the friction conductive component 4 can be adapted to the annular groove of the detection mold rod 6, ensuring the positioning of the detection mold rod 6 during movement, so that its upper half can just pass through the detection conductive component 5, and the condom product will not fall into the annular groove and contact the conductive rubber sheet 44, thereby reducing detection errors.

[0023] Furthermore, the conductive detection assembly 5 includes a mounting frame 51, which is equipped with multiple high-voltage detection plates 52 arranged on the upper and lower sides of the detection mold rod 6. The two rows of high-voltage detection plates 52 complement each other and conform to the shape of the detection mold rod 6. The length of the high-voltage detection plates 52 arranged is greater than the cross-sectional perimeter of a single detection mold rod 6. A sensor 53 is also provided on the mounting frame 51, corresponding to the entrance of the detection mold rod 6. The conductive detection assembly 5 utilizes the high-voltage detection plates 52, which are actually contoured conductive rubber, to release voltage. By conducting omnidirectional discharge detection on the product surface, the conductive rubber sheet 44 induces voltage to achieve detection feedback. The sensor 53 is configured to send a signal when the detection mold rod 6 passes, initiating voltage release.

[0024] In one embodiment, the drive assembly 3 includes a motor 31 and a drive belt 32 disposed along the guide rail 1. The motor 31 is in turn interconnected with the drive belt 32 via a synchronous pulley 33 and an encoder 34. The drive assembly 3 utilizes a servo motor to more accurately control the sliding movement of the slide assembly 2. The synchronous pulley 33 slows the angular velocity of rotation, allowing the encoder 34 to provide real-time feedback on the rotation angle to confirm the travel distance of the slide assembly 2, and thus the detection mold bars 6. Furthermore, the slide assembly 2 includes a second mounting plate 21 for mounting a plurality of detection mold bars 6. The bottom of the second mounting plate 21 is provided with a slider 22 that is slidably connected to the guide rail 1. Clamps 23 that mate with the drive belt 32 are also provided on the front and rear sides of the bottom of the second mounting plate 21 along its travel direction. The slide assembly 2 primarily maintains linear reciprocating motion by limiting the sliding movement of the slider 22 on the guide rail 1, while the clamps 23 are clamped to the drive belt 32. The drive assembly 3 controls the sliding distance of the slide assembly 2, thereby achieving a series of high-voltage pinhole detection operations.

[0025] In one embodiment, the mechanism also includes a PLC system, with the conductive rubber sheet 44, high-voltage detection board 52, sensor 53, motor 31, and encoder 34 each connected to the PLC system. Components such as a voltage adjustment knob, voltmeter, and solenoid valve can be added to the PLC system to better coordinate control and detection operations. The motor 31 drives the detection mold rod 6, and the encoder 34 controls its movement. When the detection mold rod 6 passes the sensor 53, the PLC system sends a signal to the high-voltage detection board 52 to release voltage. If a pinhole is present, the voltage will penetrate the condom product and be transferred from the detection mold rod 6 to the conductive rubber sheet 44. This voltage is then fed back to the PLC system, controlling the subsequent classification of the product on the detection mold rod 6 as defective. If there is no pinhole, the conductive rubber sheet 44 responds normally, and subsequent material discharging continues as normal.
