AI Technical Summary
The traditional fixture collision detection mechanism has too long and inconsistent suspension parts, which leads to an increase in the height of the mechanical mobile phone frame. It can only detect collisions when the fixtures are lowered, and cannot detect them during translation, causing economic losses and personal safety threats.
A fixture collision detection mechanism is designed. Through the cooperation of the suspension pin and the proximity switch, the floating adjustment of the fixture suspension assembly and the robotic connection assembly can be realized. The forward direction and bottom collision can be detected during the handling of the fixture or the object to be clamped, and the proximity switch generates a dangerous signal and stops the machine immediately.
Accurate collision detection during the handling of fixtures or objects to be clamped is achieved, the operation stability of mechanical equipment is improved, and economic losses and personal safety threats are avoided.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of clamps, in particular to a clamp collision detection mechanism. Background Art
[0002] The application of fixture collision detection mechanism in automated handling production lines is very important.
[0003] Traditional fixture collision detection mechanisms either have overly long suspension sections, resulting in overall inconsistency and increasing the height of the robot's frame. Alternatively, they only detect collisions during the fixture's descent, but not during translation. This can lead to significant economic losses and even threaten personal safety.
[0004] Worse still, there is no collision detection mechanism for the fixture, leaving the fixture carrying the clamped object without any collision protection during the handling process. If it collides with other objects or parts, it is very likely to cause certain economic losses and personal safety. Therefore, it is urgent to design a fixture collision detection mechanism to solve the above problems. Utility Model Content

[0008] The manipulator connection assembly includes a manipulator connection plate, and a suspension plate is fixedly installed on the outer walls on both sides of the bottom of the manipulator connection plate. Detection plates are installed on both sides of the suspension plate through bolts, and suspension pins distributed laterally are provided on both sides of the suspension plate.
[0009] The fixture suspension assembly includes positioning plates symmetrically arranged on both sides, side plates are installed below both sides of the positioning plates, mounting plates are provided on the outer walls of both sides of the side plates, and proximity switches are provided on the mounting plates.
[0010] Preferably, spring sheets are provided on the outer walls on both sides of the top of the suspension plate, and positioning pins are provided on the outer walls on both sides of the top of the suspension plate.
[0011] Preferably, hanging holes are provided on the outer walls on both sides of the side panels, and the hanging pins are slidably inserted into the hanging holes.
[0012] Preferably, the suspension plate is located on the inner side of the side plate, and the positioning plate covers the spring sheet and the positioning pin.
[0013] Preferably, when the bottom of the clamped object is hit, the clamp suspension assembly will move upward relative to the manipulator connection assembly, and the proximity switch on the clamp suspension assembly will detect the detection plate on the manipulator connection assembly, thereby generating a danger signal and immediately stopping the machine.
[0014] Preferably, when the clamped object is hit in the forward direction, the clamp suspension assembly will rotate around a pair of suspension pins on the collision side of the manipulator connection assembly, and the proximity switch on the clamp suspension assembly on the other side will detect the detection plate on the manipulator connection assembly, thereby generating a danger signal and immediately shutting down.
[0015] In the above technical solution, the present invention provides a fixture collision detection mechanism, which has the following beneficial effects:
[0016] The fixture collision detection mechanism of this utility model comprises a suspension pin and a side plate with a suspension hole. This allows the fixture to float and adjust along the manipulator's clamping assembly via the fixture suspension assembly. By cooperating with a proximity switch on the fixture suspension assembly and a detection plate on the manipulator's connecting assembly, collisions in the forward direction and bottom of the fixture or the clamped object can be detected during handling, providing accurate feedback and ensuring more stable operation of the entire mechanical equipment.
