Drop timing device

Abstract

A drop timing device includes a machine base, a support assembly, a lifting assembly, a lifting drive, a suction mechanism, and a sensing module. The support assembly includes a moving drive, a first support, and a second support. The moving drive is mounted on the machine base and connected to the first and second support components. The first support has a first limiting groove, and the second support has a second limiting groove. The lifting assembly includes a lifting drive and a lifting component. Both the lifting drive and the lifting drive are mounted on the machine base and connected to each other. The suction mechanism is connected to the lifting drive. The sensing module is mounted on the machine base and located on one side of the first and second support components. This drop timing device reduces the error in detecting the time it takes for the lower cover of a packaging box to separate from the upper cover under its own weight.

The first supporting surface and the second supporting surface are located on the same horizontal plane. The first supporting surface and the second supporting surface are used to support the packaging box. The first carrier member also has a first clearance hole, and the second carrier member also has a second clearance hole. The first clearance hole and the second clearance hole both extend along the horizontal direction. The first clearance hole communicates with the first supporting surface, and the second clearance hole communicates with the second supporting surface. The first clearance hole and the second clearance hole are used to avoid the sensing signal of the sensing module.

3. The drop timing device as described in claim 2, wherein, The sensing module includes a through-beam photoelectric sensor and a timer. The through-beam photoelectric sensor includes a transmitting module and a receiving module. Both the transmitting module and the receiving module are mounted on the machine tool. One of the transmitting module and the receiving module is located on the side of the first support member away from the second support member, and the other of the transmitting module and the receiving module is located on the side of the second support member away from the first support member. The optical fiber signal emitted by the transmitting module passes through the first and second clearance holes and extends toward the receiving module. The receiving module senses the position change of the lower cover relative to the upper cover based on whether it receives the optical fiber signal. The timer is electrically connected to the receiving module and is used to detect the time when the lower cover separates from the upper cover under its own gravity based on the position change of the lower cover relative to the upper cover.

4. The drop timing device as described in claim 1, wherein, The adsorption mechanism includes: a movable frame connected to the lifting drive; an assembly seat movably disposed on the side of the movable frame facing one of the first and second support members; a plurality of guide members slidingly through the movable frame in a vertical direction and connected to the assembly seat; a limiting member connected to the movable frame and extending to the side of the assembly seat opposite to the movable frame, for abutting and limiting the assembly seat; and a plurality of adsorption members spaced apart on the side of the assembly seat opposite to the movable frame and connected to the assembly seat, for adsorbing the top cover and pressing the packaging box.

5. The drop timing device as described in claim 4, wherein, The machine base is provided with a slide rail extending along the vertical direction, and the movable frame is slidably mounted on the slide rail.

6. The drop timing device as described in claim 4, wherein, The adsorption mechanism further includes a plurality of elastic elements, which are respectively sleeved on the plurality of guide elements and located between the movable frame and the assembly base. The two ends of the plurality of elastic elements are respectively connected to the movable frame and the assembly base.

7. The drop timing device as described in claim 4, wherein, The mounting base has a plurality of abutting protrusions on its side wall away from the movable frame. The plurality of abutting protrusions are arranged around the plurality of adsorption members. The distance between the abutting protrusions and the end of the plurality of abutting members facing the first and second support members is the same as that between the mounting base and the abutting protrusions. The plurality of abutting protrusions are used to abut against the upper cover.

8. The drop timing device as described in claim 4, wherein, The adsorption mechanism further includes a clamping assembly, which includes a clamping drive and two clamping members. The clamping drive is located on the movable frame, and the two clamping members are connected to the clamping drive and extend to opposite sides of the mounting base.
