Example (b):
Feeding a material tray:
a photoelectric sensor is arranged on the outer side (on a flow line) of a three-temperature chip testing and sorting machine (hereinafter referred to as a machine table), the photoelectric sensor is used for identifying whether a material tray 11 is arranged on a conveying plate 10 or not and transmitting a signal to a controller in real time, when the controller judges that the machine table is internally provided with no material tray 11, the controller controls the electromagnetic valve of the air cylinder 3 to act, the specific control air cylinder 3 retracts into a push rod, the push rod of the air cylinder 3 drives a gate connecting block 6 to move upwards, and after a pin 9 on the gate connecting block 6 moves to the uppermost position of a long slotted hole of a gate 8, the pin 9 is formally contacted with the gate 8 and drives the gate 8 to move upwards. After the push rod of cylinder 3 reached extreme position, gate 8 arrived the highest point promptly, and the time delay time is set for by the controller is inside to this time quantum, and after reaching the set time, the controller control conveyer belt 12 motor corotation utilizes conveyer belt 12 to rely on the transportation to advance the charging tray 11 inside the board.
Detecting and plugging a tray chip:
the sensor 17 transmits the acquired signals to the controller in real time, when the controller judges that the chip 13 is close to, the controller controls the cylinder 3 to extend out of the push rod, the push rod drives the gate connecting block 6 and the plunger frame 5 to move downwards, initially, the pin 9 is positioned at the uppermost part of the slotted hole and does not cause downward thrust to the gate 8, the gate 8 gradually moves downwards along with the push rod of the cylinder 3, when the follower wheel 15 on the gate 8 moves downwards until contacting the material tray 11, a certain gap is left between the gate 8 and the test chip 13 (the design sealing effect is better than that before), at the moment, the pin 9 is positioned at the position between the topmost part and the bottommost part of the slotted hole of the gate 8, namely, the gate 8 is not influenced by force, the two spring plungers 4 on the plunger frame 5 are stressed and play a role of buffering, and the follower wheel 15 is also ensured to stably press the moving material tray 11, the test chip 13 is effectively prevented from being displaced by vibration during transportation. The sensor 17 can detect whether the test chip 13 is flatly arranged in the material tray 11 or not in the transportation process, when the test chip 13 protrudes, the light intensity value of the sensor 17 is abnormal, after the controller interprets the abnormality, an alarm instruction can be triggered, meanwhile, the motor of the conveyor belt 12 is controlled to stop working, at the moment, the conveyor belt 12 stops conveying the material tray 11, and the controller prompts whether the material tray 11 needs to be withdrawn or not. If no alarm is generated, when the material tray 11 completely enters, the bottom of the follower wheel 15 is suspended at the moment, the cylinder 3 can continuously extend out of the push rod, the gate 8 gradually moves downwards along with the push rod of the cylinder 3 being pushed out, when the follower wheel 15 on the gate 8 is in surface contact with the conveying plate 10, the pin 9 is still positioned between the topmost part and the bottommost part of the long slot hole of the gate 8, namely, the gate 8 is not influenced by action force, the two spring plungers 4 on the plunger frame 5 are stressed and play a role in buffering, when the stress of the gate 8 is balanced, namely, the elastic forces of the spring plungers 4 on two sides are balanced, the resultant force of gravity and the plate surface reaction force is zero, the gate 8 stops moving, the push rod of the cylinder 3 also reaches the lowest position, and the state of the gate 8 is in a complete plugging state at the moment.
Adaptive Tilt Angle description
As shown in fig. 5, if the transfer plate 10 is not parallel to the bottom plate 1 and differs from the bottom plate by an inclination angle α, when the gate 8 descends to the bottom, the spring plungers 4 on both sides are gradually compressed and are unevenly stressed on both sides, and the compression stroke of the inner spring is different due to the different stresses of the spring plungers 4, i.e. the situation that the spring plungers are more compressed and inclined is caused. Under the action of the two spring plungers 4 which are not in the same compressed state, the shutter 8 will form a moment in the clockwise or counterclockwise direction around the pin 9, which enables the shutter 8 to tightly abut against the transfer plate 10, which also achieves the purpose of self-adjusting the angle.
Discharging a material tray:
if the material tray 11 needs to come out from the interior of the machine, when the sensor 17 receives that the detection chip 13 approaches, the signal is transmitted to the controller, the controller receives the delay signal, and the cylinder 3 is controlled to extend out of the push rod, so that the material tray 11 is ensured to reach the bottom of the gate 8 when the cylinder 3 is pushed out. The other actions are the same as the steps of the tray 11 entering, and are not described herein.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
