Description

Technical Field

[0001] This utility model relates to the field of positioning technology, and in particular to a vehicle positioning mechanism. Background Technology

[0002] With the development of intelligent manufacturing, factories are demanding increasingly higher precision and efficiency in material handling. In industries such as automotive and electronics, material handling carts need to rapidly transport goods on production lines. Because robotic arms require precise and repetitive movements, the carts must be completely fixed in the X, Y, and Z directions when parked.

[0003] In existing systems, the material feeding path of the robotic arm depends on the precise positioning of the trolley. If the trolley's position deviates, the robotic arm's movement path will deviate from the set trajectory. Especially when multiple layers are stacked, this error will accumulate, leading to material collisions or misplacement, and even affecting the operational rhythm of the entire production line. Therefore, a trolley positioning mechanism is needed to achieve multi-dimensional positioning of the trolley. Summary of the Invention

[0005] Frame;

[0006] The guiding mechanism has one end connected to the frame and guides the trolley to approach the frame.

[0007] The positioning mechanism is installed on both the trolley and the frame, and it positions the trolley.

[0008] The fixing mechanism is set on the frame and fixes the trolley.

[0009] Furthermore, the guidance mechanism includes:

[0010] A pair of support bars, which are parallel to each other, with one end of each support bar fixed to the frame and the other end of each support bar equipped with a guide ramp. The guide ramp is connected to the vertical guide wheel of the trolley to guide the trolley's travel trajectory.

[0011] A pair of guide bars are vertically fixed to the sides of a pair of support bars. The pair of guide bars are positioned between the pair of support bars and are connected to the horizontal guide wheels of the trolley.

[0031] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0032] First, combine Figs. 1~6 The present invention describes a vehicle positioning mechanism according to an embodiment of the present invention, which is used for positioning logistics vehicles and has a wide range of applications.

[0033] like Figs. 1~6 As shown, the trolley positioning mechanism of this utility model embodiment includes: a frame 1; a guiding mechanism, a positioning mechanism, and a fixing mechanism.

[0034] Specifically, such as Figs. 1~6 As shown, in this embodiment, the frame 1 provides a rigid mounting reference surface for other components; one end of the guide mechanism is connected to the frame 1, and the guide mechanism guides the trolley 5 close to the frame 1 and guides the trolley 5 to move along a preset path; the positioning mechanism is respectively set on the trolley 5 and the frame 1, and the positioning mechanism positions the trolley 5; the fixing mechanism is set on the frame 1, and the fixing mechanism rigidly fixes the trolley 5 after positioning, avoiding displacement of the trolley 5 due to vibration during the operation of the robotic arm. The frame 1 and the guide mechanism are fixed to the workshop floor with chemical bolts to ensure fixed position, effectively resist the vibration generated during the operation of the robotic arm, and have good stability.

[0035] Specifically, such as Figs. 1~6 As shown, in this embodiment, the guiding mechanism includes: a pair of support bars 21 and a pair of guide bars 22; the pair of support bars 21 are parallel to each other, one end of the pair of support bars 21 is fixed to the frame 1, and the other end of the pair of support bars 21 is provided with a guide ramp 211. The guide ramp 211 is connected to the vertical guide wheel 51 of the trolley 5, guiding the trolley 5's walking trajectory. The guide ramp 211 gradually rises from the ground to the plane of the support bar 21. The vertical guide wheel 51 of the trolley 5 rolls up along the guide ramp 211, so that the trolley 5 smoothly transitions from the ground to the bearing surface of the support bar 21. The support bars 21 allow the trolley 5 to leave the ground and prevent the trolley 5 from rolling. The pair of guide bars 22 are respectively vertically fixed to the sides of the pair of support bars 21. The pair of guide bars 22 are arranged between the pair of support bars 21. The guide bars 22 are connected to the horizontal guide wheel 52 of the trolley 5. The vertical guide bars 22 restrict the lateral displacement of the trolley 5 and correct the left and right deviation of the trolley 5 in real time.

[0036] Furthermore, such as Figs. 1~6As shown, in this embodiment, the guide bar 22 includes a parallel portion 221 and a bending guide portion 222. The parallel portion 221 is vertically fixed to the side of the support bar 21 along the length direction of the support bar 21. One end of the parallel portion 221 is close to the frame 1. The side of the parallel portion 221 continuously contacts the horizontal guide wheel 52 during the movement of the trolley 5, ensuring that the trolley 5 does not deviate left or right during the movement. The bending guide portion 222 has a front end and a rear end. The front end of the bending guide portion 222 is connected to the other end of the parallel portion 221. The distance between the bending guide portion 222 and the support bar 21 gradually increases from the front end to the rear end. Thus, the distance between the bending guide portions 222 of a pair of guide bars 22 gradually decreases from the front end to the rear end, allowing the horizontal guide wheel 52 to enter with an initial deviation, reducing the difficulty of docking, and then automatically correcting the position through the gradually tightening path.

[0037] Specifically, such as Figs. 1~6 As shown, in this embodiment, the positioning mechanism includes a first positioning block 31 and a second positioning block 32; the first positioning block 31 and the second positioning block 32 are respectively fixed on the frame 1 and the trolley 5; the first positioning block 31 has a groove, and the second positioning block 32 has a protrusion, the protrusion and the groove interlock to position the trolley 5, making positioning quick and convenient. In this embodiment, both the groove and the protrusion are V-shaped, and the V-shape has guiding properties, realizing automatic docking correction.

[0038] Specifically, such as Figs. 1~6 As shown, in this embodiment, the fixing mechanism includes a proximity sensor 41 and a clamping cylinder 42; both the proximity sensor 41 and the clamping cylinder 42 are fixed to the frame 1; when the proximity sensor 41 detects the trolley 5, the clamping cylinder 42 clamps and fixes the trolley 5 to the frame 1, preventing the trolley 5 from moving during operation. In this embodiment, there are two proximity sensors 41 and two clamping cylinders 42. The double clamping cylinders 42 can exert equal clamping force, improving stability.

[0039] Working Principle: The frame 1 of the positioning mechanism for the trolley 5 is secured to the workshop floor with chemical bolts. The guide fork is designed with a certain angle to guide the manual pushing of the trolley 5 into the positioning mechanism. The manual pushes the trolley 5 towards the support bar 21, and the horizontal guide wheels 52 on the trolley 5 move along the guide bar 22 of the positioning mechanism. The trolley 5 is pushed until it is in contact with the first positioning block 31 and the second positioning block 32. Simultaneously, the proximity sensor 41 detects that the trolley 5 has reached its position, and the clamping cylinder 42 clamps the trolley 5, thus achieving positioning. An external robotic arm can grab products and place them on the trolley 5. Once the trolley 5 is full, the clamping cylinder 42 opens, and the manual pushes the trolley 5 to the next workstation. The process is repeated with an empty trolley 5.

[0040] Above, refer to Figs. 1~6This invention describes a trolley positioning mechanism according to an embodiment of the present invention. The trolley is guided to automatically align itself using ramps and guide bars, and precisely positioned using V-shaped positioning blocks to ensure consistent placement each time. After dual sensors detect the trolley's arrival, cylinders on both sides simultaneously clamp it to prevent displacement or shaking. The entire mechanism is firmly fixed to the ground and is not easily loosened even with frequent use. It features a simple and durable structure, is easy to maintain, and is particularly suitable for automated production lines requiring rapid and precise placement of objects.
