[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figure 1-4 , the present invention provides a technical solution: a motion module obstacle detection device, including a motion module housing 1, a mover 2, a track window 3, a horizontal threaded rod 4, a support plate 5, a locking nut 6, a limiting strip 7, a limiting groove 8, a middle partition 9, a horizontal sleeve 10, an inner substrate 11, a positioning bolt 12, a positioning nut 13, an adjustment window 14, a buffer spring 15, a buffer rod 16 and a pressure sensor 17. A mover 2 is arranged on the motion module housing 1. A track window 3 is vertically penetrated through the vertical part of the mover 2. A horizontal threaded rod 4 is penetrated and installed in the track window 3. Both ends of the horizontal threaded rod 4 penetrate through the holes opened at both ends of the support plate 5. A locking nut 6 is installed at the end of the horizontal threaded rod 4. The above structural design enables the support plate 5 to conveniently slide vertically along the track window 3 with the horizontal threaded rod 4 to adjust the use height;

[0021] When using this device, install the working component on the top of the mover 2. According to the size of the working component and the installation position of the motion module housing 1, move the support plate 5 with the horizontal threaded rod 4 to slide vertically along the track window 3 until the working height of the pressure sensor 17 is appropriate, and rotate the symmetrically distributed locking nuts 6 to squeeze both ends of the support plate 5 to fit and fix with the side surface of the mover 2;

[0022] A support plate 5 is installed on the outside of the mover 2. The support plates 5 are symmetrically distributed about the center of the mover 2. The top view shape of the support plate 5 is "匚"-shaped. The above structural design ensures that the support plate 5 can be stably installed at both ends of the mover 2 and ensures the stable operation of the pressure sensor 17. A limiting strip 7 is fixedly installed on the outer wall of the vertical part of the mover 2. The limiting strip 7 fits with the inner wall of the limiting groove 8. The limiting groove 8 is vertically opened on the inner vertical surface of the support plate 5. The above structural design further improves the stability of the support plate 5 during vertical sliding and, in cooperation with the locking nut 6, strengthens the limit of the fixed support plate 5. A middle partition 9 is fixed on the outer side surface of the support plate 5;

[0023] Then move Figure 2The positioning bolt 12 in the inner base plate 11 moves along the adjustment window 14 toward the buffer rod 16, and the inner base plate 11 slides stably and linearly in the horizontal sleeve 10 and squeezes the buffer spring 15, changing the elastic potential energy stored in the buffer spring 15, that is, changing the resistance of the buffer rod 16 and the pressure sensor 17 when they are impacted and moved horizontally, until the position of the inner base plate 11 is appropriate, and the rotationally symmetrically distributed positioning nuts 13 squeeze the horizontal sleeve 10 to fix it;

[0024] Horizontal sleeves 10 are fixedly installed on both sides of the middle partition 9, and an inner base plate 11 is installed at one end of the inner side of the horizontal sleeve 10. Positioning bolts 12 are fixedly installed at the top and bottom of the inner base plate 11, and positioning nuts 13 are installed at the ends of the positioning bolts 12. The positioning bolts 12 pass through the adjustment window 14, and the adjustment window 14 is opened at the top and bottom of the horizontal sleeve 10. The positioning bolts 12 and the adjustment window 14 are slidably connected. The positioning bolts 12 and the adjustment window 14 are symmetrically distributed about the center of the inner base plate 11. The length of the adjustment window 14 is greater than 1 / 3 of the length of the horizontal sleeve 10. The above-mentioned structural design enables the inner base plate 11 to carry the positioning bolts 12 along the adjustment window 14 for a sufficient The buffer spring 15 is squeezed to different degrees to adjust the resistance of the buffer spring 15 to the buffer rod 16. A buffer spring 15 is fixed on one side of the inner base plate 11. The end of the buffer spring 15 is fixed to one end of the buffer rod 16. The buffer rod 16 is slidably connected with the hole opened at the end of the horizontal sleeve 10. The front and top cross-sections of the buffer rod 16 are both "T"-shaped. The above structural design can prevent the buffer rod 16 from being separated from the hole opened at the end of the horizontal sleeve 10, and ensure that the buffer rod 16 can perform a stable linear sliding displacement along the hole opened at the end of the horizontal sleeve 10. A pressure sensor 17 is fixed to the other end of the buffer rod 16.

[0025] The control mechanism of the motion module housing 1 can be started to drive the mover 2 and the working parts thereon to move linearly. During the movement, the pressure sensor 17 collides with an obstacle at the moment, and the obstacle squeezes the pressure sensor 17. The pressure sensor 17 slides and contracts with the buffer rod 16 into the horizontal sleeve 10 for buffering to avoid damage to the pressure sensor 17 and also provide buffering protection for the mover 2 and the working parts thereon. At the same time, when the value detected by the pressure sensor 17 is greater than the set preset value, the control mechanism of the motion module housing 1 controls the mover 2 to brake to protect the working parts. The motion module housing 1, the mover 2 and its control mechanism are all existing mature technologies, which are well known to those skilled in the art and will not be described in detail here.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
