The invention provides a sensing device which can ensure the movable seat horizontal mounting sensor and the sensing height of the sensor can be finely adjusted to improve the sensing accuracy and the use efficiency.

Press, electronic components such as ICs, resistors, electronic boards, etc., are often placed on the carrier by a robotic arm for transport operations. Because the robotic arm is in the process of picking and placing electronic components, it cannot be absolutely accurate every time. The horizontal position is placed in the positioning groove of the vehicle, and occasionally there is a tilting situation. If the tilting occurs and the abnormality is not eliminated, the positioning error will occur in the subsequent station operation process, which may result in serious The electronic components are completely damaged. Therefore, the current general equipment will be provided with sensing devices on the side of the vehicle to sense whether the electronic components are placed abnormally. If an abnormal situation is found, the sensing signals can be immediately transmitted to the controller. Stop the machine for abnormal elimination.

For example, the carrier and the sensing device of the IC test sorting machine are referred to in the first and second figures. The carrier 10 is provided with a plurality of positioning slots 11 recessed on the top surface for receiving the IC 20 and in each positioning slot 11 A groove 12 having a proper groove depth and penetrating is formed in the front and rear sides for sensing device 30 to sense whether the IC20 or IC 20 is placed in the position slot 11. The sensing device 30 is attached to the carrier 10. The first base 31 and the second base 32 are respectively disposed on the two sides. The first base 31 is provided with a screw hole 311 near the center of the top surface, and a guide hole 312 is defined on both sides of the screw hole 311. The first movable seat 33 located above the first base 31 is provided with an adjusting screw 331 at a position corresponding to the screw hole 311 of the first base 31. The adjusting screw 331 is screwed to the first base 31. The lead hole 311 and the first movable seat 33 are respectively provided with guide rods 332 of the outer sleeve springs 333 at positions corresponding to the guide holes 312 of the first base 31, and the guide rods 332 are inserted into the first base 31. In the guide hole 312, the second base 32 is also provided with a screw hole 321 at a position near the center of the top surface, and a guide hole 322 is defined on both sides of the screw hole 321 , and the second base 32 is located above the second base 32 . The second movable seat 34 is provided with an adjusting screw 341 at a position corresponding to the screw hole 321 of the second base 32, and the adjusting screw 341 is screwed into the screw hole 321 of the second base 32, and the second activity The guide 34 is disposed at a position of each of the guide holes 322 of the second base 32, and is provided with a guide rod 342 of the outer sleeve spring 343. The guide rods 342 are inserted into the guide holes 322 of the second base 32. The sensing device 30 is provided with a complex array sensor for sensing the IC 20, and each set of sensors is provided with a light source member 351 on the first movable seat 33, and is mounted on the second movable seat 32. Receiving the sensing member 352; please refer to Figures 3 and 4, because the thickness of the IC is different for different types of ICs, and the groove depth of the grooves is different for different types of carriers, so the sensing device 30 must The sensing heights of the transmitting light source member 351 and the receiving sensing member 352 of each group of sensors are adjusted according to different carriers 10A and IC20A; and the sensing height of the transmitting light source member 351 is adjusted as an example, the first movable seat can be rotated. The adjusting screw 331 of 33 adjusts the adjusting screw 331 downward in the screw hole 311 of the first base 31, and drives the first movable seat 33 and is assembled thereon. Each of the transmitting light source members 351 is synchronously lowered. The first movable seat 33 presses down the spring 333, and the guide rods 332 on both sides are displaced along the guide holes 312 of the first base 31, thereby assisting the first movable seat 33 to descend. Further, the sensing height of the light source member 351 is lowered, so that the light beam emitted from the light source member 351 can penetrate the groove 12A of the carrier 10A and be projected at a predetermined height above the IC 20A for sensing the carrier 10A. IC20A, if the IC20A is placed obliquely, it will block the light beam, then the receiving sensor 352 can not sense the light beam, and transmit the abnormal sensing signal to the controller (not shown), and control The abnormality is eliminated during the shutdown; however, the first movable seat 33 is inserted into the two guiding holes 312 of the first base 31 by using the two guiding rods 332, and assists the lifting and lowering displacement, in the component making, if the two guiding rods 332 and If the matching clearance of the two guiding holes 312 is too large, and the two sides of the first movable seat 33 are not evenly stressed, the first movable seat 33 will be tilted up and down, so that the respective light emitting parts on the first movable seat 33 are 351 can not maintain the same level of sensing height, prone to partial feeling The device misjudges the situation in which the IC20A is placed, thereby affecting the sensing accuracy of each sensor. Conversely, if the matching gap between the two guiding rods 332 and the two guiding holes 312 is too small, the two guiding rods 332 will be rubbed into the two guiding holes 312. The wall surface causes the first movable seat 33 to operate unsmoothly, and the sensing height of the sensor is not easily adjusted, resulting in poor sensing accuracy and lack of component fabrication.
