[0025] The utility model provides Figure 1-6 A blister missing detection mechanism as shown in , comprising:
[0026] The mounting mechanism 100 includes a bottom plate 101, a top plate 102, and a connecting column 103 for connecting the bottom plate 101 and the top plate 102. Two screw joint seats 104 are fixed on the top plate 102. A rotating shaft 105 is movably connected between the two screw joint seats 104. A handle 106 is fixedly connected to one side of the rotating shaft 105. Both ends of the rotating shaft 105 are keyed to eccentric wheels 107. By swinging the handle 106, the rotating shaft 105 and the eccentric wheel 107 can be driven to move;
[0027] The detection mechanism 200 includes a guide rod mounting plate 201 disposed between the bottom plate 101 and the top plate 102, a plurality of guide rods 202 are movably sleeved in the middle of the guide rod mounting plate 201, a sensing sheet 203 is fixed to the top of the guide rod 202, a plurality of mirror reflection electric eyes 204 are disposed on one side of the upper surface of the guide rod mounting plate 201, a reflector mounting strip 205 is fixed to one side of the guide rod mounting plate 201, and a plurality of reflectors 206 corresponding to the mirror reflection electric eyes 204 are fixed to one side of the reflector mounting strip 205;
[0028] The material storage mechanism 300 includes an outer box 301, a blister placement box 302 and blisters 303. The outer box 301 is arranged directly below the guide rod mounting plate 201, and the blister placement box 302 is embedded in the outer box 301. The blister placement box 302 is provided with a plurality of mounting grooves corresponding to the guide rod 202 one by one, and the blisters 303 are embedded in the mounting grooves.
[0029] In addition, a proximity switch bracket 108 is fixed to one side of the top plate 102, and a proximity switch 109 is fixed to the proximity switch bracket 108, so that the position of the guide rod mounting plate 201 can be detected by the proximity switch 109. When the proximity switch 109 detects the position of the guide rod mounting plate 201, the mirror reflection electric eye 204 is started and emits a light beam toward the reflective plate 206, and a signal of material shortage or no material shortage is sent out by judging whether the light beam is blocked by the sensor sheet 203. The bottom plate 101 is a U-shaped structure and is spliced by three independent plates. The size of the groove on the bottom plate 101 matches the size of the outer box 301, so as to facilitate quick positioning of the outer box 301.
[0030] Specifically, two downward pressure guide pillars 207 are fixed on the top of the guide rod mounting plate 201. The top ends of the two downward pressure guide pillars 207 pass through the top plate 102 and correspond to the two eccentric wheels 107 respectively. When the eccentric wheel 107 rotates, the corresponding downward pressure guide pillars 207 can be pushed downward, thereby driving the guide rod mounting plate 201 to move downward. A self-lubricating copper sleeve is provided at the junction of the downward pressure guide pillars 207 and the top plate 102, which can lubricate the up and down movement of the downward pressure guide pillars 207.
[0031] It is worth mentioning that a slide groove is provided at the top of the downward pressing guide column 207 , and the top of the downward pressing guide column 207 is movably sleeved on the corresponding eccentric wheel 107 to ensure that the eccentric wheel 107 can rotate on the top of the downward pressing guide column 207 .
[0032] Specifically, the bottom ends of the plurality of guide rods 202 and the top ends of the plurality of blisters 303 are spaced the same distance apart to ensure that when the guide rod mounting plate 201 moves downward, the plurality of guide rods 202 can contact the corresponding blisters 303 at the same time, thereby ensuring the accuracy of the missing detection.
[0033] It should be noted that the sensing sheet 203 is arranged between the mirror reflection electric eye 204 and the reflective plate 206, and is used to block the light beam emitted by the mirror reflection electric eye 204. When the blister 303 is installed in the blister placement box 302, the guide rod 202 contacts the blister 303 after the guide rod mounting plate 201 moves downward. After contacting the blister 303, the guide rod 202 rises and causes the sensing sheet 203 to separate from the mirror reflection electric eye 204, thereby giving a no-material-shortage signal. If the mirror reflection electric eye 204 is still blocked, a missing signal is given.
[0034] Specifically, a voice broadcast device electrically connected to the detection mechanism 200 is provided on the outside of the installation mechanism 100. By receiving a signal indicating no shortage of material or a signal indicating shortage of material, a corresponding voice broadcast is issued, so that the staff can quickly obtain the shortage detection information.
[0035] Working principle: When the blister missing detection mechanism is used, firstly, the outer box containing the blister 303 is embedded in the groove of the bottom plate 101, and then the handle 106 is manually swung to drive the rotating shaft 105 and the eccentric wheel 107 to rotate. When the eccentric wheel 107 rotates, it can push the downward guide column 207 downward, thereby driving the detection mechanism 200 to move downward. When the detection mechanism 200 moves downward, the guide rod 202 rises after contacting the blister 303, and lifts the sensor sheet 203 upward. Whether there is a lack of material is determined by the different signals emitted by the mirror reflection electric eye 204 when it is blocked, which greatly improves the efficiency and accuracy of missing detection.
[0036] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
