Description

Technical Field

[0001] This utility model belongs to the technical field of laser ranging components for feeding carts, specifically relating to a laser ranging component for a feeding cart. Background Technology

[0002] A feeding trolley generally refers to a device that can move along a track to multiple designated feeding positions for feeding materials. A laser ranging component is used during the movement and stopping of the feeding trolley. This component measures the distance to the feeding trolley in real time, and then, after the trolley reaches the feeding position, the control unit stops the trolley to allow feeding, thus ensuring the feeding trolley stops accurately at different feeding positions.

[0003] Laser ranging components typically consist of a transmitting unit and a reflecting unit. The transmitting unit is usually a ToF sensor or a phase-detection laser rangefinder, capable of emitting laser light and receiving reflected signals. The reflecting unit is typically a microprism reflector, capable of reflecting the laser light. The transmitting unit is usually fixed to a wall along the direction of movement of the feeding trolley, making position adjustment inconvenient. The reflecting unit is generally fixed to the feeding trolley. After installing the transmitting unit, the position of the reflecting unit needs to be adjusted to ensure that the laser light shines perpendicularly or at a fixed angle onto the reflecting unit; otherwise, the measurement error will increase significantly.

[0024] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0025] like Figures 1 to 4 As shown in one embodiment of this utility model, a laser ranging component for a feeding trolley includes a base 11, a first protective plate 12 fixedly connected to the base 11, and a second protective plate 13 fixedly connected to the first protective plate 12. A hopper is provided on the base 11, and casters are provided at the bottom of the base 11. A motor or other driving structure can move the casters, thereby moving the feeding trolley along a track. When the feeding trolley moves to the feeding position, the hopper opens to feed material. The first protective plate 12 and the second protective plate 13 provide protection for the entire feeding trolley.

[0026] The laser ranging component includes a reflector 21, a mounting bracket 31 on the reflector 21, a first adjusting plate 41 on the mounting bracket 31, a clamp 51 on the first adjusting plate 41 that matches the base 11, the first protective plate 12, and the second protective plate 13, an adjusting groove is formed in the first adjusting plate 41, and a second adjusting plate 52 that matches the adjusting groove is fixedly connected to the clamp 51.

[0027] A first adjusting plate 41 is provided with a first threaded hole 42, and a first fixing bolt 43 is threadedly connected in the first threaded hole 42. A second threaded hole is provided in the gripper 51, and a second fixing bolt 55 is threadedly connected in the second threaded hole.

[0028] Specifically, the reflector 21 is installed on the feeding trolley. After the transmitting unit is fixed, the position of the reflector 21 can be adjusted on the feeding trolley to ensure that the light beam emitted by the transmitting unit is perpendicular to or irradiates on the reflector 21 at a fixed angle.

[0029] See Figure 4 As shown, the gripper 51 can be stuck on the base 11, the first protective plate 12 or the second protective plate 13. The gripper 51 can move on the base 11, the first protective plate 12 or the second protective plate 13, thereby driving the reflector 21 to move and adjusting the position of the reflector 21. The first adjusting plate 41 can extend and retract on the second adjusting plate 52, thereby further adjusting the position of the reflector 21.

[0030] The first fixing bolt 43 can abut against the second adjusting plate 52 to ensure the stability of the first adjusting plate 41 after extension and retraction. The second fixing bolt 55 can abut against the base 11, the first protective plate 12 or the second protective plate 13, so that the gripper 51 is stably fixed on the base 11, the first protective plate 12 or the second protective plate 13.

[0031] The gripper 51 is fixed on the base 11, the first protective plate 12 or the second protective plate 13, and thus the position of the reflector 21 can be adjusted from multiple angles. After the transmitting unit is fixed, when the light beam emitted by the transmitting unit is outside the reflector 21, it is convenient to adjust the position of the reflector 21 so that the light beam emitted by the transmitting unit is perpendicular to or irradiates on the reflector 21 at a fixed angle.

[0032] A fixing disk 54 is fixedly connected to the second fixing bolt 55. A groove 53 matching the fixing disk 54 is provided in the gripper 51, and anti-slip lines are provided on the fixing disk 54.

[0033] When the second fixing bolt 55 is rotated, the second fixing bolt 55 can drive the fixing disk 54 to move, increasing the contact area with the base 11, the first protective plate 12 or the second protective plate 13 through the fixing disk 54, increasing the friction force through the anti-slip lines, and increasing the stability of the gripper 51 fixed on the base 11, the first protective plate 12 or the second protective plate 13.

[0034] The mounting bracket 31 is in the shape of a drawer. The upper end and the side end of the mounting bracket 31 have openings. A side plate 36 is provided at the side end of the mounting bracket 31. The reflector 21 is located inside the mounting bracket 31. The surface of the reflector 21 reflecting the laser is flush with the upper end surface of the mounting bracket 31, preventing the mounting bracket 31 from blocking the reflector 21 to form a shadow and affecting the reflection.

[0035] The front and rear ends of the reflector 21 are respectively provided with cross alignment lines 22. The cross alignment lines 22 make it easy to make the beam of light shine on the center position of the reflector 21 perpendicularly or at a fixed angle, which can maximize the signal strength, eliminate geometric errors, and improve the anti-interference ability.

[0036] A limiting groove 23 is provided on the reflector 21. A limiting plate 32 that matches the limiting groove 23 is fixedly connected inside the mounting frame 31. The limiting plate 32 can be snapped into the limiting groove 23, so as to fix the reflector 21 in the mounting frame 31. A pin 35 is provided on the mounting frame 31. A baffle 34 is rotatably connected to the pin 35. By rotating the baffle 34, the side end of the reflector 21 can be blocked to prevent the reflector 21 from falling off the mounting frame 31.

[0037] A handle 24 is fixedly connected to the reflector 21, which facilitates pulling the reflector 21 out of the mounting bracket 31. A side plate 36 is fixedly connected to the mounting bracket 31, and a cleaning plate 33 is provided on the side plate 36. The cleaning plate 33 is a rubber plate with elasticity and can abut against the non-reflective surface of the reflector 21. A protective cavity is formed between the reflector 21 and the mounting bracket 31.

[0038] Specifically, the back of the reflector 21 is located inside the protective cavity. When dust adheres to the front of the reflector 21, i.e. the reflective surface, the reflector 21 can be pulled out by the handle 24. When the reflector 21 is pulled out, the back should face forward, and then it can be installed in the mounting bracket 31. During the movement of the reflector 21, the side with dust can be cleaned by the cleaning plate 33. The side located inside the protective cavity is always clean and serves as the reflective surface.

[0039] When using, refer to Figures 1-4 As shown, once the transmitting unit is fixed, the position of the laser emitted by the transmitting unit is fixed. The clamp 51 can be fixed on the base 11, the first protective plate 12 or the second protective plate 13 respectively, and the position of the reflector 21 can be initially adjusted. The position of the reflector 21 can be further adjusted by the first adjustment plate 41 and the second adjustment plate 52, so that the beam emitted by the transmitting unit shines on the reflector 21 vertically or at a fixed angle.

[0040] Compared with the prior art, the laser ranging component of the feeding trolley of this utility model makes it easy to adjust the position of the reflecting unit on the feeding trolley, so that the laser emitted by the emitting unit can be irradiated on the reflecting unit perpendicularly or at a fixed angle, thereby reducing measurement error.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
