Description

Technical Field

[0001] The utility model relates to the field of measuring devices, and more specifically, to a vertical positioning device. Background Art

[0002] A vertical positioning device is a device used to accurately determine the vertical position of an object, and infrared sensors are a common type. After infrared light is emitted and reflected by an object, the vertical position of the object is determined based on information such as the intensity and time difference of the reflected light. In some automated warehousing systems, infrared sensors are used to detect the vertical position of goods on shelves to prevent improper placement of goods.

[0003] Due to factors such as the building and working environment, it may not be possible to achieve very precise positioning by relying solely on the stroke control of the electric push rod in the vertical positioning device. The electric push rod frequently pushes parts for positioning. If it relies on the stroke limit to stop each time, it is easy to cause excessive wear of the electric push rod's lead screw, nut and other components as well as connected components, thereby affecting the measurement life of the vertical positioning device. Utility Model Content

[0004] In response to the problems existing in the prior art, the purpose of the present utility model is to provide a vertical positioning device. In this solution, when the upper horizontal plate contacts the lower inner wall of the secondary beam, the multiple downward-pressing vertical rods in the upper slot on the upper horizontal plate can be subjected to the extrusion force first. The downward-pressing vertical rods can accurately sense the moment of contact with the target object, so that the controller stops the lifting of the electric push rod according to this signal, avoiding damage to the electric push rod due to excessive propulsion, thereby ensuring the overall measurement efficiency of the positioning device.

[0005] In order to solve the above problems, the present invention adopts the following technical solutions.

[0006] A vertical positioning device includes a positioning device arranged on the front side of a vertical wall, a secondary beam is fixedly connected to the upper side of the front end of the vertical wall, the positioning device includes a lower base, an electric push rod is fixedly connected to the left side of the upper end of the lower base, and the right side of the lower end of the electric push rod is fixedly connected to the lower horizontal plate, the output end of the electric push rod is fixedly connected to the upper horizontal plate, the lower end of the upper horizontal plate is fixedly connected to a signal receiver, and the upper end of the lower horizontal plate is fixedly connected to a signal transmitter, the signal transmitter and the signal receiver cooperate with each other, an upper end of the upper horizontal plate is provided with an upper slot, the lower inner wall of the upper slot is fixedly connected to an inner cavity opening, the lower inner wall of the inner cavity opening is fixedly connected to a spring member, the upper end of the spring member is fixedly connected to a downward pressure vertical rod, and the lower inner wall of the upper slot is fixedly connected to a plurality of contact sensors.

[0007] Furthermore, an inner cavity opening is formed at the lower end of the downward pressing vertical rod, and the spring member is located in the inner cavity opening.

[0008] Furthermore, a plurality of contact sensors cooperate with corresponding downward-pressing vertical rods, and the downward-pressing vertical rods contact the lower inner wall of the secondary beam.

[0009] Furthermore, a pair of displacement wheels is provided at the lower end of the lower base, and the two displacement wheels are symmetrically arranged with respect to each other.

[0010] Furthermore, a slotted bin is provided at the inner end of the lower base, and a plurality of counterweight inner blocks are filled at the inner end of the slotted bin.

[0011] Furthermore, the multiple counterweight inner blocks are horizontally equidistantly distributed, and the positioning device is equipped with a built-in controller.

[0012] Furthermore, the controller is electrically connected to the electric push rod, the signal receiver, the signal transmitter and the contact sensor through wires, and the controller is externally connected to a control terminal.

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] (1) In this solution, the appraiser places the positioning device against the front of the vertical wall, and when the electric push rod is lifted, when the upper horizontal plate contacts the lower inner wall of the secondary beam, the multiple downward-pressing vertical rods in the upper slot on the upper horizontal plate can first be subjected to the squeezing force, and then the spring member that presses the downward-pressing vertical rod into position below it is compressed into the inner cavity and makes the bottom of the downward-pressing vertical rod contact with the contact sensor. The contact sensor can send a signal at the moment of contact to stop the electric push rod from working. The downward-pressing vertical rod can accurately sense the moment of contact with the target object, so that the controller stops the lifting of the electric push rod according to this signal, avoiding damage to the electric push rod caused by excessive propulsion, thereby ensuring the overall measurement efficiency of the positioning device.

[0015] (2) At the same time, a slotted bin is provided in the lower base. The multiple counterweight inner blocks in the slotted bin can improve the positioning accuracy of the lower base at the bottom of the positioning device. The counterweight inner blocks lower the center of gravity of the positioning device, thereby ensuring that the vertical angle of the signal transmitter and the upper horizontal plate is more accurate, making the electric push rod on the positioning device more stable in the vertical direction.
