Abstract
The utility model discloses an inversion detecting device used for a syringe needle and aims to provide the syringe needle inversion detecting device with high detecting speed and high accuracy. According to the scheme, whether needle inversion occurs or not can be judged based on light reflecting volume of the needle. After a tool clamp strip equipped with the syringe needle is conveyed to a detection station through a conveying belt, a light emitter emits light to the detection station. A light receiver detects and sends received light intensity to a control module. The control module compares the detected light intensity with a threshold value. If the detected light intensity exceeds the threshold value, the needle on the detection station is judged as inverted. If the detected light intensity is smaller than the threshold value, the needle is judged to be in a correct state. Then a light emitting diode is utilized for displaying and a needle dismounting mechanism is used for dismounting the inverted needle. The inversion detecting device provided by the utility model can detect the syringe needle efficiently and accurately at low cost and with high practicality. Delivery pass rate of products can be guaranteed effectively and the inversion detecting device is suitable for all syringe need manufactures.

The utility model is mainly solved by following technical proposals for above-mentioned technical matters: a kind of syringe needle falls needle detecting device, comprise frock clamp bar, travelling belt, be arranged on scanner head and position Fibre Optical Sensor on slide rail, detection station and the control module of You Xie pin mechanism, described scanner head comprises optical transmitting set and optical receiver, described position Fibre Optical Sensor comprises the second optical transmitting set and the second optical receiver, described frock clamp bar is provided with some erection columns that coordinate with syringe needle, on side of frock clamp bar, have 50 and erection column test hole one to one, the center of all test holes is on same straight line, the center of all erection columns is on same straight line, the side that frock clamp bar has test hole is smooth flat, reflectivity is greater than 70%, the second optical receiver can receive the stronger light of returning from the offside reflection of frock clamp bar, frock clamp bar is pushed into and detects station test hole strafing on face in the time that position Fibre Optical Sensor moves later, test hole bottom is disc, the second optical transmitting set emits beam and is scattered while being irradiated to test hole, now the second optical receiver can only detect weak reflected light, detect station be provided with 50 with erection column one to one the light emitting diode of red green two looks as indicator, optical transmitting set and optical receiver are arranged on the top of testing agency, and the transmit direction of optical transmitting set and the receive direction of optical receiver are all just to syringe needle, optical transmitting set, optical receiver, position Fibre Optical Sensor, Xie Zhen mechanism and light emitting diode are all connected with control module.
Thereby scanner head can move inswept detection station on slide rail.
As preferably, described Xie Zhen mechanism is arranged on detects station below, and described erection column center has unloads pin through hole.Unload needle construction and comprise that one is unloaded pin motor and one and unloads shank, unload shank and can under the driving of motor, stretch into and unload pin through hole and retract; The described pin motor that unloads is connected with control module.
When the light intensity receiving when optical receiver is greater than threshold value, the sequence number of system log (SYSLOG) current station, whole frock clamp bar unclamps the clamp system including stabilization clamp after detecting and finishing, and starts Xie Zhen mechanism the syringe needle of falling pin that is recorded sequence number is unloaded and drops into waste product frame.
As preferably, syringe needle falls needle detecting device and also comprises stabilization clamp, and described stabilization clamp is clamped in the draw point part of the syringe needle being sleeved on frock clamp bar.Stabilization clamp clamps the draw point part of all syringe needles on frock clamp bar point-blank, can keep stable, and ensure accuracy of detection.Stabilization clamp is the ingredient of clamp device.
The substantial effect that the utility model brings is, do not need high investment and professional operating personnel, and detection speed is fast, and recall rate is high, simple to operate, ensured the qualification rate of producing product.
