Description

Technical Field

[0001] This utility model relates to the field of automation technology, and in particular to an automatic stop device. Background Technology

[0002] Stop mechanisms are widely used in automated production equipment. The requirements for stop mechanisms in automated operations include simple and practical structure, easy control, durability and long lifespan, convenient maintenance, high impact load capacity, and the ability to quickly switch between different products. However, most current stop mechanisms directly use the piston rod of the cylinder as the load-bearing point. When the load is too large or the number of uses is too high, the stop mechanism is prone to failure. Therefore, improvements are needed. Utility Model Content

[0013] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] Reference Figure 1 As shown, this utility model provides an automatic stop device. In one embodiment, it includes a mounting bracket 1, a rotary drive mechanism 2 mounted on the mounting bracket 1, and a stop block 3 connected to the rotary drive mechanism 2. A sensing bracket 4 is also connected to the mounting bracket 1, and one end of the sensing bracket 4 extends to one end of the stop block 3. An upper sensor 41 and a lower sensor 42 are respectively installed at the top and bottom of one end of the sensing bracket 4. A sensing plate 31 is connected to one end of the stop block 3 near the sensing bracket 4, and a downwardly extending pressing part 32 is provided at the other end of the stop block 3. In this embodiment, the stop block 3 (the shape and structure of the sensing plate 31 and the pressing part 32 of the stop block 3 are not limited) functions to apply downward pressure or lift the product or pallet module for release; the rotary drive mechanism 2 (the rotary drive mechanism 2 can be a motor, cylinder, etc., and is not limited thereto; in a preferred embodiment, a stepper motor is used) functions to rotate forward or backward according to the received signal, thereby driving the stop block 3 to perform the action of pressing down or lifting up; the mounting bracket 1 serves to fix the device, and the mounting bracket 1 has a fixing hole, into which screws can be locked to fix the stop mechanism at the position where the device needs to perform the stop action; the model and type of the upper sensor 41 and the lower sensor 42 are not limited; in a preferred embodiment, the upper sensor 41 and the lower sensor 42 are slotted photoelectric sensors, which function to sense the state of the stop block 3: pressing down or lifting up.

[0015] Preferably, in this embodiment, the sensing plate 31 is integrally connected with the stop block 3, and the sensing plate 31 has a fan-shaped structure; the rotary drive mechanism 2 includes a rotary motor mounted on the mounting bracket 1; a mounting hole is provided in the middle of one side of the stop block 3, and the stop block 3 is connected to the output shaft of the rotary motor through the mounting hole; a locking hole 33 is also provided on the top of the stop block 3, which extends into the mounting hole, and the locking hole 33 is used to install screws to lock and fix the stop block 3 and the output shaft of the rotary motor.

[0016] In this embodiment, the stop block 3 has a shaft hole in the middle that is connected to the motor. The motor drives the stop block 3 to rotate. A screw is installed in the locking hole 33 at the top to fix the motor shaft to the stop block 3. At the same time, one end of the stop block 3 has a fan-shaped feature. When the motor runs, it drives the stop block 3 to move, so that the fan-shaped structure rotates into or out of the slot-shaped photoelectric sensing area. In addition, the other end of the stop block 3 is a "7"-shaped pressure head (pressure part 32). When the motor runs, the pressure head applies pressure to the product or tray module when it is pressed down, thereby stopping the product or tray module. When the pressure head is lifted, the product or tray module is released.

[0017] In one embodiment, the mounting bracket 1 includes a mounting vertical plate 11 and a mounting horizontal plate 12 connected to one side of the mounting vertical plate 11 and arranged perpendicularly to the mounting vertical plate 11; the rotary drive mechanism 2 is mounted on one side of the mounting horizontal plate 12, and an upper extension plate 13 and a lower extension plate 14 extend outward from the upper and lower parts of the other side of the mounting horizontal plate 12, respectively; the stop block 3 is arranged near the other side of the mounting horizontal plate 12 and is located between the lower extension plate 14 and the upper extension plate 13; a lower buffer pad 15 is installed on the top of the lower extension plate 14, and an upper buffer pad 16 is installed on the bottom of the upper extension plate 13.

[0018] In another embodiment, the mounting bracket 1 includes a mounting vertical plate 11 and a mounting horizontal plate 12 connected to one side of the mounting vertical plate 11 and arranged perpendicularly to the mounting vertical plate 11; the rotary drive mechanism 2 is mounted on one side of the mounting horizontal plate 12, and a lower extension plate 14 extends outward from the lower part of the other side of the mounting horizontal plate 12; the stop block 3 is arranged near the other side of the mounting horizontal plate 12 and is located above the lower extension plate 14; a lower buffer pad 15 is also installed on the top of the lower extension plate 14; a protrusion extends outward from the upper part of one end of the stop block 3 connected to the sensing plate 31; an upper buffer pad 16 is also installed on the side of the sensing bracket 4 near the stop block 3, corresponding to the protrusion.

[0019] In summary, the sensing bracket 4 is connected to the upper part of the mounting vertical plate 11, and the lower part of the mounting vertical plate 11 is also provided with fixing holes. The upper buffer pad 16 and the lower buffer pad 15 are mainly used to limit the stop block 3 and reduce the impact force when it performs the pressing and lifting actions.

[0020] The operation of this utility model is as follows: When the motor receives a signal that material has arrived, it starts the motor and drives the stop block 3 to rotate. The pressing part 32 of the stop block 3 performs a pressing action. The fan-shaped structure at the tail of the stop block 3 rotates away from the sensing area of ​​the lower sensor 42 and into the sensing area of ​​the upper sensor 41. When it contacts the lower buffer pad 15, it stops and maintains the pressing state. When the motor receives the release signal, it starts to reverse and drive the stop block 3 to lift up, releasing the pressed product. The fan-shaped structure at the tail of the stop block 3 moves away from the sensing area of ​​the upper sensor 41 and into the sensing area of ​​the lower sensor 42. It stops rotating when it contacts the upper buffer pad 16.

[0021] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
