Description

Technical Field

[0001] The invention relates to a detection device, in particular to a multi-station glove leak detector. Background Art

[0002] Gloves are a common item used in food processing, biomedicine and other fields. Plastic silicone gloves are particularly common in the biomedicine field. For example, they are worn on the hands during experiments, or used by the operator's hands to operate inside and outside the space. Therefore, the air tightness of the gloves needs to be tested before use.

[0003] The glove leak detector is a testing device specially used to detect the air tightness of gloves. Its main working principle is to inject compressed air into the gloves, and stop the air injection when the preset pressure value is reached; stop for a period of time, observe whether the pressure inside the gloves changes, and then determine whether the gloves are intact and undamaged. The detection operation of the existing glove leak detector is to first manually pull the cuff of the glove to make it expand elastically, and then put the glove cuff on the leak detection disk of the leak detector, and then manually use the tightening mechanism to achieve a fixed seal between the glove and the leak detection disk, and then the glove leak detection operation can be performed. A large part of the above operation process still needs manual operation. When faced with a large number of gloves, the manual workload is large and the labor cost is high, which does not conform to the company's future development concept. Summary of the invention

[0004] The purpose of the present invention is to provide a multi-station glove leak detector, which uses machinery to replace manual labor to achieve leakage detection of gloves, thereby reducing manual workload and labor costs, which is more in line with the future development concept of the enterprise.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: a multi-station glove leak detector, comprising a mounting frame, a plurality of leak detectors arranged on the mounting frame, and a feeding mechanism, which is configured to realize the transmission and feeding of gloves to be tested; a transmission mechanism, which is configured to receive the gloves on the feeding mechanism and realize the subsequent transmission of the gloves; an opening mechanism, which is configured to realize the opening of the glove cuffs on the transmission mechanism; an expansion mechanism, which is configured to expand the glove cuffs after opening to a diameter larger than the diameter of the leak detection disk set of the leak detector; a set mechanism, which is configured to set the gloves and cuffs after the expansion of the expansion mechanism on the top of the leak detection disk; a tightening mechanism, which is configured to tighten and seal both the leak detection disk and the gloves.

[0006] By adopting the above technical solution, the gloves to be tested are fed through the feeding mechanism, and the gloves on the feeding mechanism are transferred to the next workstation under the action of the transmission mechanism. During the transmission process, the gloves are opened through the opening mechanism, so that the subsequent expansion mechanism can smoothly enter the cuff of the glove to expand the gloves and cuffs. The diameter of the expanded gloves and cuffs is larger than the leak detection disk, so that the gloves can be smoothly put on the leak detection disk of the leak detector under the action of the set mechanism. Then, the tightening mechanism is set to achieve the tightening and sealing between the leak detection disk and the gloves, and then the leak detector can be controlled to realize the leak detection operation of the gloves; after the operation is completed, the gloves can be discharged manually. The above mechanism replaces manual labor to realize the leakage detection of gloves in a mechanical way, thereby reducing the workload and labor costs, which is more in line with the future development concept of the enterprise.

[0007] It is further configured as follows: the tightening mechanism includes multiple groups of reset components and tightening components, the tightening components cooperate with the multiple groups of reset components to synchronously realize the tightening and sealing between each leak detection disk and the glove, the expansion mechanism and the suit mechanism are both configured as multiple groups, and the multiple groups of reset components, expansion mechanisms and suit mechanisms are all configured one-to-one with multiple leak detection disks.

[0008] By adopting the above technical solution, the tightening component cooperates with multiple sets of reset components to realize the tightening and sealing operation of the gloves on each leak detection disk. This structure is simpler, the processing cost is lower, the control operation is more reliable, and the probability of failure is greatly reduced.

[0009] It is further configured as follows: the feeding mechanism includes a feeding conveyor belt, a feeding placement station arranged on one side of the feeding conveyor belt, and a feeding drive component that drives the gloves from the feeding conveyor belt to the feeding placement station. A grabbing notch is provided on the feeding placement station. When the gloves are placed at the feeding placement station, the gloves are placed horizontally and the upper outer side and the lower side of the gloves near the cuff are both in communication with the outside.

[0010] By adopting the above technical solution, the feeding conveyor belt can realize the transmission of the gloves to be tested, and the gloves on the feeding conveyor belt are transmitted to the feeding placement station through the set feeding drive component. Due to the shape characteristics of the gloves, the set grasping notch enables the mechanism to realize stable grasping and transmission of the gloves, thereby improving the feasibility of the mechanism.

[0011] It is further configured as follows: the feed drive assembly includes a fixed frame, a guide slide groove arranged on the fixed frame, a slide seat slidably arranged on the guide slide groove and reciprocating between the feed conveyor belt and the feed placement station, a feed suction cup arranged on the slide seat, and a feed drive member driving the slide seat to move, the guide slide groove includes a disengagement section and a conveying section connected to the disengagement section in sequence from the feed conveyor belt to the feed placement station, the horizontal height of the disengagement section is located above the conveying section, and when the slide seat is located in the disengagement section, the feed suction cup cannot grab the gloves.

[0012] By adopting the above technical solution, when not working, the slide is located in the disengagement section, so that the existing feed suction cup will not interfere with the normal transmission operation of the gloves. When the gloves are to be transmitted, the feed drive drives the slide to drive the feed suction cup to move from the disengagement section to the conveying section. Since the height of the conveying section is lower than the disengagement section, the feed suction cup can grasp and convey the gloves, thereby transferring the gloves from the feed conveyor belt to the feed placement station. This structure completes the movement of the slide in two dimensions through a driving method, which is simple in structure and lower in cost.

[0013] It is further configured as follows: the transmission mechanism includes a base frame, a moving seat horizontally slidably arranged on the base frame, a screw rotatably arranged on the base frame and threadedly connected to the moving seat, a transmission driving member driving the screw to rotate, and a manipulator moving with the moving seat.

[0014] By adopting the above technical solution, the transmission drive drives the screw to rotate, drives the moving seat and the manipulator to move through the threaded structure, and cooperates with the set manipulator to realize the transmission operation between the gloves and each leak detection disk, thereby completing the transmission operation of the gloves.

[0015] The invention is further configured as follows: the opening mechanism is arranged at the output end of the manipulator, and the opening mechanism includes an opening frame arranged at the output end of the manipulator, two opening suction cups slidably arranged on the opening frame toward or away from each other, linkage racks respectively connected to the two opening suction cups, linkage gears meshing with the two linkage racks, and an opening driving member driving the linkage gears to rotate, and an opening area for gloves to enter and exit is formed between the two opening suction cups.

[0016] By adopting the above technical solution, the manipulator operates the opening mechanism to move the glove into the opening area, and then drives the two opening suction cups to move toward each other with the cooperation of the opening drive, linkage gear and linkage rack to realize the two-point grasping operation on the outer wall of the glove. After completing the grasping operation of the glove, the two opening suction cups are driven to move away from each other to realize the opening operation of the glove cuff. The above mechanism is used to realize the opening operation of the glove during the transmission process, and the two steps are carried out simultaneously, thereby shortening the process time and improving the processing efficiency.

[0017] It is further configured as follows: the expansion mechanism includes a telescopic sleeve arranged in front of the leak detection disk, an expansion chamber formed in the telescopic sleeve, an expansion air pipe connecting the expansion chamber and the leak detector air pump, and a guide rod arranged in the expansion chamber and extending away from the leak detection disk, and the leak detection air outlet on the leak detection disk is located outside the expansion chamber.

[0018] By adopting the above technical solution, the expanded glove moves toward the expansion mechanism under the action of the transmission mechanism and the cuff of the glove is put on the outside of the telescopic sleeve. Then the leak detector works, firstly supplying air to the telescopic sleeve through the expansion air pipe to make it expand and then expand the glove and cuff, so as to complete the expansion operation of the glove and cuff. The guide rod can ensure that the glove is smoothly put on the outside of the telescopic sleeve, so as to improve the feasibility of the mechanism.

[0019] The further configuration is as follows: the sleeve mechanism comprises a sleeve ring which is sleeved on the outer periphery of the leak detection disk and is reciprocatingly slidable along the axis of the leak detection disk, a plurality of expansion slots formed on the front end surface of the sleeve ring and for the glove cuff to be inserted into, and a driving cylinder which drives the sleeve ring to reciprocate, the plurality of expansion slots are distributed around the center of the sleeve ring, a guide insert is formed at the front end of the sleeve ring between each expansion slot and the inner ring of the sleeve ring, and extends toward the front end of the sleeve ring and is gradually narrowed, and the guide insert guides the glove cuff into the expansion slot.

[0020] By adopting the above technical solution, the telescopic sleeve expands and supports the glove and cuff to an expanded state, and then the cylinder drives the ring to move toward one side of the glove, and the guide insert is inserted into the gap between the cuff and the telescopic sleeve along with the movement of the ring, and the cuff enters the expansion slot under the action of the guide insert to expand and position the cuff and the glove. Then, the telescopic sleeve is deflated to shrink, and then the reset ring can drive the glove to move toward the leak detection disk and fit on the outer ring of the leak detection disk, thereby completing the glove fitting operation on the leak detection disk. The guide insert is set to a gradually shrinking structure and combined with the telescopic characteristics of the telescopic sleeve, so that the guide insert can be stably inserted into the gap between the cuff and the telescopic sleeve, thereby improving the reliability and feasibility of the structure.

[0021] It is further configured as follows: the tightening assembly includes a tightening rope fixed at one end and a reel connected to the other end of the tightening rope and used to tighten the tightening rope, and the tightening rope is wound around the position corresponding to each leak detection disk to form a tightening ring mounted on the outer ring of the leak detection disk.

[0022] By adopting the above technical solution, the tightening ring formed by the tightening rope is simple in structure and low in cost. When the reel pulls the tightening rope, each tightening ring can be contracted and tightened synchronously, thereby achieving the purpose of tightening and sealing. In addition, the sealing structure has a more complete contact surface and a better and more stable sealing effect. Through the above structure, after the gloves are put on, the tightening rope can steadily tighten and fix the gloves, thereby avoiding interference in the structure.

[0023] It is further configured as follows: the reset assembly includes a plurality of reset rings connected to the tightening ring and a reset spring connecting each reset ring and the sleeve ring, the reset rings are distributed around the center of the leak detection disk, the tightening ring is located at the front end of the expansion slot opening and at the outer circle of the expansion slot, and one of the reset rings is sleeved on the intersection position forming the tightening ring.

[0024] By adopting the above technical solution, the tightening ring pulls the reset spring through the reset ring to cause stretching deformation during the tightening process. When the force acting on the tightening ring is released, the tightening ring is expanded and reset under the action of the reset spring, thereby achieving the tightening purpose. And by fitting one of the reset rings to the intersection position of the tightening ring, a stable tightening ring structure is formed without interfering with the tightening movement of the tightening ring.

[0025] In summary, the present invention has the following beneficial effects: the present invention uses machinery to replace manual labor to achieve leakage detection of gloves, thereby reducing manual workload and labor costs, which is more in line with the future development concept of the enterprise.
