The number of cars on the road is increasing year by year, and more and more people own private cars. This widespread adoption of automobiles has brought about the development of automotive parts manufacturing and design. In the automotive processing, material handling vehicles are needed to facilitate the transport of automotive parts.

[0003] The robot picks up and places parts on a small car for precise positioning. The multi-model material car can switch between different models. However, switching between models requires manual switching. During manual switching, there is a risk of missing parts in the positioning rotation mechanism. Therefore, a multi-model switching precision positioning car was proposed. Utility Model Content

[0008] Furthermore, the first infrared emitter is installed at an angle, and the second infrared emitter is installed vertically to the support column. The infrared rays emitted by the first infrared emitter can pass through the staggered openings on the two rotating plates, and the infrared rays emitted by the second infrared emitter are not blocked by the rotating plates, so there is no missed switching state.

[0009] Furthermore, the top outer surface of the material cart is provided with a plurality of evenly distributed placement components, which are used to place the cart parts.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: Please refer to the following: Figures 1-7 This utility model provides a technical solution: a multi-vehicle switching precision positioning trolley, including a garage 100, a material cart 200, two rotary positioning components 300, and a detection component. The material cart 200 is used to place vehicle parts and enters the garage 100 for positioning. The rotary positioning components 300 are located on top of the material cart 200 and are used for switching between multiple vehicle models. The detection components are located on both sides of the garage 100 and are used to detect the rotary positioning components 300 to avoid missed cutting. Specifically, the rotary components are used to switch between multiple vehicle models, and the detection components are used to detect the rotary positioning components 300 to avoid missed cutting.

[0019] Furthermore, the rotary positioning assembly 300 includes a base 301 fixed above the material cart 200. A rotary plate 304 is rotatably connected to the top of the base 301, and a positioning plate is fixedly connected to the bottom of the rotary plate 304. A connecting seat 302 is fixedly connected to one side of the base 301. A positioning pin 303 is movably inserted between the connecting seat 302 and the positioning plate. The other end of the positioning pin 303 is movably inserted into the interior of the base 301. Two through holes 305 are opened on the outer surface of the rotary plate 304. Specifically, the rotary positioning assembly 300 can be manually switched by the operator to be in different states. When switching, the positioning pin 303 is pulled to release the restriction between the positioning plate and the connecting seat 302, so that the rotary plate 304 can rotate, thereby switching between different vehicle models.

[0020] Furthermore, the detection assembly includes two support columns 400, located on either side of the garage 100. A first infrared emitter 401 and a second infrared emitter 402 are mounted externally on each support column 400. The first infrared emitter 401 is installed at an angle, while the second infrared emitter 402 is installed perpendicular to the support column 400. The infrared rays emitted by the first infrared emitter 401 can pass through the staggered openings 305 on the two rotating plates 304, and the infrared rays emitted by the second infrared emitter 402... If the switch is not blocked by the rotating plate 304, there is no missed switching state. Specifically, when the switch is completed, the infrared rays emitted by the first infrared emitter 401 and the second infrared emitter 402 are directed to pass through the two intersecting openings 305. The first infrared emitter 401 emits an angled infrared ray, which is then directed to pass through the two intersecting openings 305. The second infrared emitter 402 sends a signal so that it is not blocked by the rotating plate 304. When a switch is missed, the rotating plate 304 will block the infrared rays, thereby enabling the detection of the switching state of the rotating positioning component 300 and avoiding missed switching states.

[0021] Furthermore, the top outer surface of the material cart 200 is provided with a plurality of evenly distributed placement components 500, which are used to place the parts.

[0022] Furthermore, the placement component 500 includes a fixed column 501 fixed above the material cart 200. Multiple positioning blocks 502 are disposed inside the fixed column 501, and multiple pins 503 are inserted inside the fixed column 501. The positioning blocks 502 are rotatably sleeved on the outside of the pins 503. Multiple levers are rotatably disposed inside the fixed column 501, with one end of each lever engaging with the positioning block 502. Specifically, the robot performs the gripping and placing operation. The robot places the workpiece on the first layer of the placement component 500. During placement, the workpiece is placed on the positioning block 502, and the positioning block 502 rotates under the action of the pins 503, causing the levers of the first layer to pop out the levers of the second layer, thereby popping out the positioning block 502 of the second layer. The principle is the same during gripping.

[0023] Furthermore, a limit component 600 is provided on one side of the garage 100, which is used to limit the material cart 200 inside the garage 100.

[0024] Furthermore, the limiting component 600 includes a cylinder installed at one end of the garage 100. The output end of the cylinder is connected to a limiting block. A limiting groove is opened at one end of the material cart 200. The limiting block is adapted to the limiting groove. Specifically, when the detection component detects that no missing switching has occurred, the cylinder is activated. The cylinder drives the limiting block to insert into the limiting groove, thereby limiting the material cart 200 and causing the material cart 200 to lock in the garage 100.

[0025] Furthermore, the garage 100 is equipped with multiple guide rods 101 inside. The guide rods 101 are used to guide the material cart 200 into the garage 100. Specifically, the guide rods 101 guide the material cart 200 when it enters the garage 100, so that the material cart 200 enters the garage 100 accurately.

[0026] Working Principle: In use, the rotating positioning component 300 is manually switched by the operator to different states. During switching, pulling the positioning pin 303 releases the restriction between the positioning plate and the connecting seat 302, allowing the rotating plate 304 to rotate, thus switching between different vehicle models. After the material cart 200 is pushed into the garage 100, an infrared transmitter emits a signal. When the switching is complete, the first infrared transmitter 401 and the second infrared transmitter 402 emit infrared rays. The first infrared transmitter 401 emits angled infrared rays, which pass through two intersecting openings 305. The second infrared transmitter 402 sends a signal, preventing the infrared rays from passing through. The infrared light will be blocked by the rotating plate 304. When a cut is missed, the rotating plate 304 will block the infrared light, thereby detecting the switching state of the rotating positioning component 300 and avoiding missed switching states. After receiving the signal, the receiving end limits the trolley through the limiting component 600 to fix the material trolley 200. Then, the robot performs the gripping and placing work. The robot places the trolley on the first layer of the placement component 500. During placement, the trolley is placed on the positioning block 502, and the positioning block 502 rotates under the action of the pin 503, which drives the first layer's lever to pop out the second layer's lever, thereby popping out the second layer's positioning block 502. The principle is the same when gripping.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
