Description

Technical Field

[0001] The present invention relates to the technical field of automated production of lithium-ion soft-pack batteries PACK, and in particular to a rapid and precise positioning mechanism for a rail trolley. Background Art

[0002] With the development of society, the use of mobile phones has increased, and the speed of replacement has continued to accelerate. Soft-pack batteries are widely used in digital products. The production of soft-pack batteries has also gradually evolved from manual production and semi-automated production to the current fully automated PACK line modular production. To improve product production efficiency, product quality yield, and economic considerations, we have changed the previous method of transporting batteries between equipment to a method of fixing and adsorbing batteries on a trolley for production, achieving stable, fast, and precise positioning during the transport process, greatly improving production efficiency. However, the existing trolley for quickly transferring soft-pack PACKs on the carrier has certain drawbacks. The trolley carrying the battery cannot achieve a fast and stable deceleration and stop process while transporting it on the track. The moving trolley on the track affects the continued transportation of other trolleys, causing collisions between trolleys. In addition, the trolley carrying the battery cannot stop stably while transporting it on the track, and the precise positioning mechanism cannot quickly and accurately position the trolley. Summary of the Invention

[0003] The main purpose of the present invention is to provide a rapid and precise positioning mechanism for a rail trolley, which can effectively solve the problem in the background technology that the trolley carrier with a battery cannot achieve rapid and stable deceleration and stop during transportation on the track. The trolley moving on the track line affects the continued transportation of other trolleys, thereby causing collisions between trolleys. In addition, the trolley carrier with a battery cannot stop stably during transportation on the track, and the precise positioning mechanism cannot quickly and precisely position the trolley carrier.

[0004] To achieve the above object, the technical solution adopted by the present invention is:

[0005] A rail trolley rapid precision positioning mechanism comprises a trolley track line and a trolley carrier, the trolley carrier is arranged above the trolley track line, a carrier battery position is provided on the surface of the trolley carrier, a track line belt is provided on one side of the trolley track line, a fixing frame is provided on one side of the trolley track line, a power separation workpiece and a precision positioning cam are provided on the fixing frame, a trolley elastic structure surface is provided on one side of the trolley carrier, and the trolley elastic structure surface is in contact with the track line belt, and a trolley follower wheel is provided on the side wall of the trolley elastic structure surface, which is located close to the power separation workpiece.

[0011] As a preferred technical solution, the trolley carrier moves along the track line belt of the trolley track line, and the trolley elastic structure surface of the trolley carrier contacts the track line belt of the track line belt.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In the present invention, a trolley elastic structure surface, a trolley follower wheel and a power separation workpiece are provided, so that the follower wheel on the side of the trolley elastic structure surface in the equipment will be lifted up and retracted by the nearby power separation workpiece and separated from the physical contact with the belt. At this time, the trolley will start to slow down and stop to prepare for fine positioning without affecting the continued transportation of other trolleys on the track line. A guide workpiece, a fine positioning cam and a fine positioning slot are provided, which can quickly fine position the trolley. While the trolley carrier is running on the track, the trolley starts to slow down when it approaches the fine positioning mechanism until the cam of the fine positioning mechanism is completely stuck in the fine positioning slot on the trolley to complete the fine positioning. The above actions are performed simultaneously, which changes the previous steps of stopping first and then positioning, and directly improves the working efficiency of the equipment.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-6 As shown, a rail trolley rapid precision positioning mechanism includes a trolley track line 1 and a trolley carrier 3, the trolley carrier 3 is arranged above the trolley track line 1, and a carrier battery position 4 is provided on the surface of the trolley carrier 3, a track line belt 2 is provided on one side of the trolley track line 1, a fixed frame is provided on one side of the trolley track line 1, and a power separation workpiece 7 and a precision positioning cam 9 are provided on the fixed frame, and a trolley elastic structure surface 5 is provided on one side of the trolley carrier 3, which is located flush with the power separation workpiece 7, and the trolley elastic structure surface 5 is in contact with the track line belt 2, and the side wall of the trolley elastic structure surface 5 is located on the side close to the power separation workpiece 7 and is provided with a trolley follower wheel 6.

[0023] As a preferred technical solution, a bidirectional V-wheel is provided on the trolley track line 1 between the track line belts 2, and a drive motor is provided on one side of the trolley track line 1, and the drive motor is connected to one of the bidirectional V-wheels.

[0024] As a preferred technical solution, the surface of the carrier battery position 4 is provided with an adsorption magnet or a clamping device, and the carrier battery position 4 is fixed to the battery through the adsorption magnet or the clamping device.

[0025] As a preferred technical solution, a torsion spring and a rotating rod are provided inside the trolley carrier 3 above the trolley elastic structural surface 5, and the rotating rod is in contact with the trolley elastic structural surface 5, the lower surface of the trolley elastic structural surface 5 is in contact with the track belt 2, and the trolley elastic structural surface 5 floats in the vertical direction, and the trolley follower wheel 6 is located on the trolley elastic structural surface 5.

[0026] As a preferred technical solution, the position of the trolley follower wheel 6 matches the position of the power separation workpiece 7, and the power separation workpiece 7 is provided with an inclined surface that matches the trolley follower wheel 6.

[0027] As a preferred technical solution, the lower surface of the guide workpiece 8 is provided with an inclined surface, and the precision positioning slot 10 is located at the end of the inclined surface, and the precision positioning slot 10 matches the shape of the precision positioning cam 9 .

[0028] As a preferred technical solution, the trolley carrier 3 moves along the track line belt 2 of the trolley track line 1, and the trolley elastic structural surface 5 of the trolley carrier 3 contacts the track line belt 2 of the track line belt 2.

[0029] It should be noted that the present invention is a rapid precision positioning mechanism for a rail trolley. When the trolley carrier 3 needs to be transported on the trolley track line 1, the trolley and the carrier are the trolley carrier 3. The trolley carrier 3 is stably driven by being clamped on the trolley track line 1 by a bidirectional V-wheel, and the battery is adsorbed on the carrier battery position 4. The elastic structural surface 5 of the trolley extends toward the belt surface, and will produce elastic friction contact with the track line belt 2. Therefore, when the belt rotates, the trolley carrier 3 is carried on the trolley track line 1. During the transportation process, the trolley follower wheel 6 starts to guide the trolley elastic structural surface 5 to retract when it contacts the inclined surface of the power separation workpiece 7, thereby breaking away from the contact with the track line belt 2. At the same time, the precision positioning cam 9 on the precision positioning mechanism starts to contact the inclined surface of the guide workpiece 8. The trolley will continue to move forward with inertia deceleration until the precision positioning cam 9 is engaged in the precision positioning slot 10 on the trolley to complete the precision positioning of the trolley carrier 3. This precision positioning is completed while decelerating. Compared with the old carrier that first stops completely and then performs the positioning action, it saves more time. Because the elastic structure surface 5 of the trolley is out of contact with the track belt 2, the trolley has lost its main power. Therefore, when the trolley follower wheel 6 and the power separation workpiece 7 are in contact, the reverse elastic force of the trolley elastic structure surface 5 will cause the reaction force between the trolley follower wheel 6 and the power separation workpiece 7 to produce a certain deceleration; at the same time, the precision positioning cam 9 on the precision positioning mechanism and the inclined surface of the guide workpiece 8 begin to contact, and the resistance of the reverse elastic force of the precision positioning cam 9 will also produce a first certain deceleration for the trolley that has lost its main power.

For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
