Description

Technical Field

[0001] This utility model relates to the field of spray gun operation technology, specifically a universal sensing mechanism. Background Technology

[0002] During setup or operation, robotic spray guns may collide with the workpiece or surrounding objects, potentially causing damage. Currently, there are no external protective devices for this, relying primarily on products with consistent dimensions and the operator's skill. If the product's shape is irregular or its placement is off, the robot may collide with the workpiece during automatic spraying. Additionally, errors by beginners during initial setup may cause the spray gun to collide with workpieces or factory buildings. For unimportant workpieces, the consequences of such collisions are relatively minor and generally negligible. However, for delicate objects, the damage from such collisions can be quite severe. Utility Model Content

[0003] The purpose of this invention is to provide a universal sensing mechanism that can sense collisions with objects from multiple angles of the spray gun and trigger an alarm through sensors, causing the robot to stop moving, thus avoiding collisions with workpieces and reducing unnecessary losses.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a universal sensing mechanism, the structure of which includes a sensing mechanism body and a mounting base connected to the spray gun. At least one sensing body is provided on one side of the mounting base. The sensing body includes a sleeve, a sensor mounting plate, an inductive sensor, a trigger assembly, a small shaft, a probe, a set screw, and a connector. One end of the sleeve is provided with the sensor mounting plate, and the other end of the sleeve is provided with a connector connected to the mounting base. The inductive sensor is connected to the sensor mounting plate. One side of the trigger assembly is connected to the inductive sensor, and the other side of the trigger assembly is connected to the small end of the small shaft. The large end of the small shaft is equipped with the probe and is fixedly connected by a set screw.

[0005] Furthermore, the triggering component includes a sleeve, an elastic sheath, a screw, a compression spring, and a spring washer. The sleeve is fitted onto the inductive sensor and one end is connected to the internal components of the sleeve via a connector. The other end of the sleeve is connected to the small shaft via a screw, a compression spring, and a spring washer. The elastic sheath is fitted onto the outside of the connection between the small shaft and the sleeve.

[0006] Furthermore, the inner ring of the elastic sheath is provided with a spacer.

[0007] Furthermore, the inductive sensor is electrically connected to the alarm.

[0008] Furthermore, the mounting base includes a base, an ear seat, and a fixing member. One side of the base is connected to the extension seat of the spray gun by multiple bolts. At least one ear seat is provided on the outer side of the base. The ear seat has an insertion hole at its center that mates with the end of the sleeve. The rear side of the ear seat has a fixing member that is fixed to the end connector of the sleeve.

[0009] Furthermore, the fastener includes a fixing plate and fastening bolts. The fixing plate has fixing holes at its four corners. The fastening bolts pass through the fixing holes of the fixing plate and the lug in sequence and are then fastened to the connector.

[0010] The beneficial effects of this utility model are:

[0011] This utility model's universal sensing mechanism is installed at one end of the spray gun processing base. By setting multiple sensing mechanism bodies on the outer circumference of the mounting base, the sensor can be triggered from multiple angles, reducing or avoiding collisions with the workpiece. The workpiece is a drone. In its natural state, the elastic sleeve and compression spring keep the small shaft and inductive sensor coaxial. When the spring receives an external force, the small shaft wobbles or moves inside the sleeve. When the screw approaches the inductive sensor, the sensor sends a signal, triggering an alarm. Upon receiving the alarm, the robot stops moving, thus ensuring that the sensing mechanism moves away from the sensor before the spray gun collides, preventing damage to the drone.

[0020] The universal sensing mechanism of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] like Figures 1 to 5 As shown, the universal sensing mechanism proposed in this utility model includes a sensing mechanism body and a mounting base 16 connected to the spray gun. At least one sensing body is located on one side of the mounting base 16. The sensing body includes a sleeve 1, a sensor mounting plate 3, an inductive sensor 9, a trigger assembly, a small shaft 5, a probe 7, a set screw 12, and a connector. One end of the sleeve 1 is provided with the sensor mounting plate 3, and the other end of the sleeve 1 is provided with a connector 15 connected to the mounting base. This connector is fixedly installed on the outside of the sleeve 1 by a nut, and the side wall of the nut has a fixing hole that mates with the fastening bolt 165 of the mounting base 16. The inductive sensor 9 is connected to the sensor mounting plate 3. One side of the trigger assembly is connected to the inductive sensor 9, and the other side of the trigger assembly is connected to the small end of the small shaft 5. The large end of the small shaft 5 is fitted with the probe 7 and fixedly connected by the set screw 12. The inductive sensor 9 is electrically connected to an alarm; after receiving a touch signal, the inductive sensor activates the alarm.

[0022] The triggering assembly includes a sleeve 4, an elastic sheath 8, a screw 14, a compression spring 10, and a spring washer 11. The sleeve 4 is fitted onto the inductive sensor 9, and one end is connected to the internal components of the sleeve via a connector 13. The other end of the sleeve is connected to the small shaft 5 via the screw 14, the compression spring 10, and the spring washer 11. The elastic sheath 8 is fitted onto the outside of the connection between the small shaft 5 and the sleeve 4. The inner ring of the elastic sheath 8 has a spacer 6 for sealing. When the small shaft 5 moves, the screw 14 shifts closer to the inductive sensor 9, and the inductive sensor sends a signal to trigger the alarm.

[0023] like Figure 5 , Figure 6 As shown, the mounting base 16 includes a base 161, an ear seat 162, and a fixing member. One side of the base 161 is connected to the extension seat 18 of the spray gun 17 by multiple bolts. At least one ear seat 161 is provided on the outer side of the base 161. The center of the ear seat 161 has an insertion hole 163 that mates with the end of the sleeve 1. The rear side of the ear seat 161 has a fixing member that is fixed to the end connector 15 of the sleeve 1. The fixing member includes a fixing plate 164 and fastening bolts 165. The four corners of the fixing plate 164 are respectively provided with fixing holes. The fastening bolts 165 pass through the fixing holes of the fixing plate 164 and the ear seat 161 in sequence and are then fastened to the connector 15.

[0024] The number of ear mounts 162 on the mounting base 16 can be freely selected according to different usage requirements. For example Figure 1 and Figure 5 As shown, the base 161 of the mounting base is circular in shape, and five ear seats 162 are provided on the outer circumference of the base. One ear seat is left empty to avoid interference and to allow space for painting and gun washing.

[0025] In its natural state, the elastic sleeve and compression spring keep the small shaft and the inductive sensor coaxial. When the spring is subjected to external force, the small shaft wobbles or moves inside the sleeve. When the screw approaches the inductive sensor, the sensor sends a signal, the alarm sounds, and the robot stops moving upon receiving the alarm information. This ensures that the sensing mechanism moves away from the sensor before the spray gun collides with it, thus avoiding damage to the drone.

[0026] The above description is merely an illustration of some principles of this utility model. This specification is not intended to limit this utility model to the specific structure and applicable scope shown. Therefore, all possible modifications and equivalents that may be used fall within the scope of the patent application of this utility model.

[0027] Apart from the technical features described in the specification, all other technical features are known to those skilled in the art.
