Description

[0002] In the traditional loading pipe falling device, the loading pipe mainly slides into the upper and lower receiving tables under the action of its own gravity. However, due to the light weight, low surface friction coefficient and easy deformation of the plastic loading pipe, when it slides in the obliquely designed loading pipe clip, the tail of the loading pipe often warps due to uneven resistance of the contact surface with the guide rail, resulting in that the loading pipe cannot move smoothly to the horizontal receiving table. When the horizontal receiving table performs the horizontal conveying action, the warped tail of the loading pipe is easy to interfere with the equipment structure, triggering the moving failure alarm, which seriously affects the production efficiency. Especially in the high-precision semiconductor packaging scene, the posture deviation of the loading pipe will also cause the position deviation of the device, and further cause the misplacement of the loading pipe or the damage of the device.

[0035] Furthermore, as a preferred embodiment, it also includes: a first cylinder, which is disposed at the lower end of the upper and lower support platforms 4, and the output shaft of the first cylinder is connected to the upper and lower support platforms 4.

[0036] Furthermore, as a preferred embodiment, it also includes: a second cylinder, which is disposed inside the worktable 1, and the output shaft of the second cylinder is connected to the horizontal receiving platform 5.

[0037] Furthermore, as a preferred embodiment, the horizontal receiving platform 5 includes: a base plate and a base 52. The base plate is rectangular and is located between the two upper and lower receiving platforms 4. The output shaft of the second cylinder is connected to the base plate, and the base 52 is provided at the corner of the base plate.

[0038] Furthermore, as a preferred embodiment, the horizontal receiving platform 5 also includes: a sliding rod 53 and a slider. The two sliding rods 53 are arranged parallel to each other on both sides of the base plate, and both ends of each sliding rod 53 are connected to the base 52. The lower end of the slider is provided with a connecting hole, through which the sliding rod 53 passes, and the slider can slide along the sliding rod 53.

[0039] Furthermore, as a preferred embodiment, the upper end of the slider is provided with a receiving seat 55, and the receiving seat 55 is provided with a plurality of fixing grooves, which are arranged linearly along the axial direction of the slider 53.

[0040] Furthermore, as a preferred embodiment, a third cylinder is provided on the base plate, and a third cylinder is provided on one side of each slide rod 53. The output end of the third cylinder is connected to the corresponding slider and is used to drive the slider to move axially along the slide rod 53.

[0041] Furthermore, in a preferred embodiment, air holes are provided on the upper and lower receiving platforms 4, one end of the vacuum nozzle 41 is disposed in the air hole, one end of the air pipe 42 extends into the air hole and is connected to the vacuum nozzle 41, the other end of the air pipe 42 is connected to the vacuum solenoid valve, and the vacuum solenoid valve is connected to the PLC controller.

[0042] Furthermore, as a preferred embodiment, a vacuum pressure sensor is provided on the air pipe 42. The vacuum pressure sensor is further connected to a PLC controller and is used to detect whether the vacuum nozzle 41 is gripping the loading pipe.

[0043] The working principle of this utility model is as follows: First, the upper and lower receiving platforms 4 move upward under the drive of the first cylinder, and at the same time, the vacuum solenoid valve starts to work. At this time, the vacuum pressure sensor will detect whether the pressure on the vacuum nozzle 41 has reached the preset value. If the set value has not been reached, the vacuum pressure sensor will transmit the signal to the PLC controller, and the PLC controller will then control the alarm to sound. At the same time, the new type of loading tube falling device stops working. If the set value has been reached, the baffles set opposite each other in the first loading tube clip 2 and the second loading tube clip 3 will move towards each other under the action of the fourth cylinder 61. The device moves in the near direction until the baffle moves between the two adjacent, vertically distributed feeding tubes. At this point, the baffle provides support for the upper feeding tube to prevent it from falling into the upper and lower receiving platforms 4. The lower feeding tube is firmly sucked onto the vacuum nozzle 41 and pressed against the upper and lower receiving platforms 4 by the suction force of the vacuum nozzle 41. Then, the upper and lower receiving platforms 4 move downward under the action of the first cylinder, so that the outer wall of the feeding tube abuts against the bottom wall of the fixed groove. At this time, the vacuum pressure sensor sends the detected pressure to the PLC controller. When the PLC controller determines that the pressure detected by the vacuum pressure sensor has not changed compared to before, it means that the feeding tube has failed to enter the horizontal receiving platform 5, and the PLC controller controls the new feeding tube falling device to stop working. When the PLC controller determines that the pressure detected by the vacuum pressure sensor has changed compared to before, the PLC controller controls the vacuum solenoid valve to close. After the vacuum solenoid valve closes, the vacuum pressure sensor also closes. The PLC controller checks again whether the vacuum pressure sensor has stopped working. If the vacuum pressure sensor has not stopped working, it means that the vacuum solenoid valve has failed to close, and the PLC controller controls the new feeding tube falling device to stop working. When the feeding tube lowering device stops working, if the vacuum pressure sensor stops working, the slider, driven by the third cylinder, slides from the end of the slide rod 53 near the upper and lower receiving platforms 4 to the end of the slide rod 53 away from the upper and lower receiving platforms 4. Then, after the external feeding mechanism fixes one end of the feeding tube, the base plate moves downward under the drive of the second cylinder so that the feeding tube is disengaged from the fixing groove. The slider then slides from the end of the slide rod 53 away from the upper and lower receiving platforms 4 to the end of the slide rod 53 near the upper and lower receiving platforms 4 under the drive of the third cylinder. The base plate moves upward to its original position under the drive of the second cylinder.
