Description

A tooling in place detection device

Technical Field

The utility model relates to the technical field of detection devices, in particular to a tooling in place detection device.

Background Art

When the workpiece enters the spray station in the cleaning equipment, there will be a nozzle spraying water in the station space during operation, and the water vapor density is relatively high. Ordinary electrical components cannot be used in this environment, so the position of the tooling is transmitted to the dry environment outside the equipment through the movement of the mechanism for inspection.

In-place detection in common equipment is to design a photoelectric device at the position of the tooling to directly detect whether there is an object in the photoelectric area. If the object blocks the photoelectric device, the photoelectric device will generate a signal, and the signal reaches the PLC to make a judgment. The current problem with in-place detection is that the usage method is relatively single, and the working environment cannot meet the requirements of a humid or long-flowing water environment.

Utility Model Content

In view of the deficiencies in the prior art, the utility model provides a tooling in place detection device to solve the problem that the sensor cannot be used in an extremely humid working environment or in a working environment with long-flowing water.

The utility model is realized through the following technical solutions:

Provided is a tooling in-place detection device, which is installed on a tooling conveyor line and includes a blocking component and an in-place detection component.

The blocking assembly includes a blocking shaft rotatably mounted between two side plates in the length direction of the tooling conveyor line, and a blocking cylinder mounted on one side plate of the workpiece conveyor line, at least one blocking plate is fixed on the blocking shaft, one end of the blocking shaft penetrates the side plate on which the blocking cylinder is mounted and is connected to the piston rod of the blocking cylinder through a crank arm;

The in-place detection component includes a detection shaft and a proximity switch. The detection shaft passes through and is rotatably installed on the side panel where the blocking cylinder is set. One end of the detection shaft inside the side panel is connected to a swing rod, and the other end of the detection shaft outside the side panel is connected to a detection rod. The proximity switch is installed on the side panel and directly opposite to the highest swing point of the detection rod.

Furthermore, a roller capable of rolling contact with the bottom surface of the tooling is installed at the end of the swing rod.

A roller is installed at the end of the swing rod to reduce the friction between the swing rod and the bottom surface of the tooling, and the roller guide is used to facilitate the tooling to press the swing rod down and drive the detection rod at the other end of the detection shaft to tilt up.

Furthermore, the included angle between the orthographic projection of the swing rod and the detection rod is an obtuse angle.

The included angle between the swing rod and the positive projection of the detection rod is an obtuse angle, so that when the swing rod swings, it can drive the detection rod to tilt upward, so that it cooperates with the proximity switch to perform signal sensing.

Beneficial effects of the utility model:

The utility model utilizes a mechanical structure in conjunction with a proximity switch to transmit the mechanical movement inside the device to the outside of the device. After being transmitted to the outside, the detection switch is used to avoid the adverse effects of a large amount of water vapor environment on the detection device, greatly improving the stability and accuracy of the detection device, and reliably detecting the operation status inside the device, solving the problem that the detection switch cannot be installed in a humid environment with a lot of water flow.

DETAILED DESCRIPTION

In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

As shown in Figures 1-4, a tooling in-place detection device is installed on a tooling conveyor line, and includes a blocking component and an in-place detection component.

The blocking assembly includes a blocking shaft 7 rotatably installed between two side plates 1 in the length direction of the tooling conveyor line, and a blocking cylinder 2 installed on one side plate 1 of the workpiece conveyor line. At least one blocking plate 8 is fixed on the blocking shaft 7. In this embodiment, two blocking plates 8 are arranged at intervals on the blocking shaft 7. One end of the blocking shaft 7 passes through the side plate 1 on which the blocking cylinder 2 is installed and is connected to the piston rod of the blocking cylinder 2 through the crank arm 3.

The in-position detection component includes a detection shaft 6 and a proximity switch 5. The detection shaft 6 passes through and is rotatably installed on the side plate 1 where the blocking cylinder 2 is set. One end of the detection shaft 6 inside the side plate 1 is connected to a swing rod 10, and the end of the swing rod 10 is installed with a roller 9 that can roll in contact with the bottom surface of the tooling.

One end of the detection shaft 6 outside the side plate 1 is connected to the detection rod 4, and the proximity switch 5 is installed on the side plate 1 and faces the highest swing point of the detection rod 4. The angle between the swing rod 10 and the positive projection of the detection rod 4 is an obtuse angle, such as the angle α shown in FIG5 .

The use process of this utility model after installation:

When the tooling moves on the tooling conveyor line, the blocking cylinder 2 installed on the side plate 1 will extend, and the piston rod will drive the crank arm 3 to swing and then drive the blocking shaft 7 to rotate. After the blocking shaft 7 rotates, it drives the blocking plate 8 to be in an upright blocking state to block the tooling. The tooling will stop after touching the blocking plate 8. At this time, the end of the swing rod 10 will be pressed down by the tooling and drive the detection shaft 6 to rotate. After the detection shaft 6 rotates, it drives the detection rod 4 outside the side plate 1 to tilt upward counterclockwise. When the detection rod 4 tilts upward at a certain angle (reaching the highest point), it will be detected by the proximity switch 5 installed on the side plate 1. The PLC controller electrically connected to the proximity switch 5 will receive the signal and regard it as the tooling in place.

When the piston rod of the blocking cylinder 2 retracts, it will pull the crank arm 3 to move in the opposite direction, and then the blocking shaft 7 will rotate to drive the blocking plate 8 to be in a flat release state, and the tooling will pass through the area smoothly. After the tooling passes through the area, the detection rod 4 will automatically swing down due to the influence of gravity, causing the proximity switch 5 to lose the signal. At this time, it is considered that there is no tooling in this area.

Of course, the above description is not limited to the above examples. The technical features not described in the present invention can be achieved by or by adopting the existing technology, which will not be repeated here. The above embodiments and drawings are only used to illustrate the technical scheme of the present invention and are not limitations of the present invention.
