Description

Technical Field

[0001] This utility model belongs to the field of electric vehicle manufacturing technology, and specifically refers to an automatic feeding device for electric vehicle motor wheels. Background Technology

[0002] In the electric vehicle manufacturing industry, the motor wheel is one of the core components, and its production efficiency and assembly precision directly affect the performance and quality of the entire vehicle. In the traditional electric vehicle motor wheel production process, the handling, clamping, and stacking of the motor wheels usually rely on manual operation or semi-automated equipment.

[0003] Furthermore, the motor wheels are typically placed on pallets. After the semi-automatic equipment finishes gripping the motor wheels on the pallet, a new pallet still needs to be placed manually before the equipment can grip it again. This semi-automatic equipment can usually only complete a single task and cannot achieve automatic stacking of multiple pallets, still requiring human intervention. At the same time, manual operation is prone to inaccurate gripping of the motor wheels due to fatigue or operational errors, affecting production quality. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic feeding device for electric vehicle motor wheels, which can efficiently and accurately complete the clamping of motor wheels and the automatic stacking of pallets, thereby improving production efficiency.

The synchronous linkage group is symmetrically distributed in an S-shape on the horizontal projection plane.

[0011] The present invention is further configured such that the two vertical roller frames are located on both sides of the front half section of the two roller frames, the horizontal rollers of the front half section of the two roller frames are short horizontal rollers, and an assembly notch for fork insertion is formed between two adjacent short horizontal rollers, and the horizontal rollers of the rear half section of the two roller frames are long horizontal rollers.

[0018] 1.

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1 — Figure 4 :

[0034] An automatic feeding device for electric vehicle motor wheels includes a truss handling mechanism 1 and a conveying mechanism 2 disposed on a base surface;

[0035] The conveying mechanism 2 includes a placement frame 20 disposed above the base surface for placing pallets. A roller frame 21 is disposed on one side of the placement frame 20. The roller frame 21 includes two sets of parallel and facing roller frames 22. Several horizontal and parallel transverse rollers 23 are disposed within the roller frames 22. Inwardly facing vertical roller frames 24 are disposed on the outer sides of both roller frames 22, and several longitudinal and parallel vertical rollers 25 are fixed on the vertical roller frames 24 along the length of the roller frames 22.

[0036] The truss handling mechanism 1 includes a frame truss 10 fixed above the base surface. A first slide 11 is slidably mounted on the top of the frame truss 10, and its sliding direction is perpendicular to the length direction of the roller frame 21. A motor wheel clamp 3 that slides longitudinally is mounted on the first slide 11. A second slide 12 is fixed on the rear column of the frame truss 10, and its sliding direction is parallel to the length direction of the roller frame 21. A tray clamp 4 that slides longitudinally is mounted on the second slide 12.

[0037] In the specific implementation process, the motor wheels placed above the pallet are continuously conveyed to the end of the roller frame 21 by the horizontal roller 23, so that the motor wheel clamp 3 on the first slide 11 can be clamped and used to complete the subsequent assembly operation. After all the motor wheels on the pallet have been gripped, the pallet clamp 4 on the second slide 12 grips the empty pallet and places it on the shelf 20 to realize the stacking of the pallets.

[0038] In the above structure, the pallet clamp is a traditional servo motor or cylinder driven clamp, and the clamp arm of the clamp is formed with a clamping opening, which facilitates action on the arc-shaped outer wall of the motor wheel.

[0039] Preferably, the pallet clamp 4 includes a clamp frame 40, with clamping arms 41 of the same structure slidingly disposed at both ends of the clamp frame 40, a synchronous linkage group 42 disposed between the two clamping arms 41, and two driving cylinders 43 that drive the clamping arms 41 to move closer or further apart in the horizontal direction are fixed on the clamp frame 40.

[0040] Preferably, the synchronous linkage group 32 includes a rotating shaft 44 rotatably disposed in the middle of the clamp frame 40, a first connecting rod 45 rotatably connected to the rotating shaft 44, and the two ends of the first connecting rod 45 are respectively hinged to the middle of the two clamping arms 41 through a second connecting rod 46 with the same structure. The synchronous linkage group 42 is symmetrically distributed in an S-shape on the horizontal projection plane.

[0041] In the above structure, the drive cylinder 43 drives any clamping arm 41, and the synchronous linkage group 32 realizes the synchronous movement of the other clamping arm, which improves the clamping accuracy and stability, and effectively improves the pallet stacking efficiency.

[0042] Preferably, the two vertical roller frames 24 are located on both sides of the front half section of the two roller frames 21, the horizontal rollers of the front half section of the two roller frames 21 are short horizontal rollers 26, and an assembly notch 260 for forks to extend into is formed between two adjacent short horizontal rollers 26, and the horizontal rollers of the rear half section of the two roller frames 21 are long horizontal rollers 27.

[0043] Preferably, the front sides of the two sets of vertical roller frames 24 form a funnel-shaped opening structure.

[0044] In the above structure, the forklift transports the stacked pallets. Typically, a certain number of motor wheels are placed on each pallet. The forks are inserted into the assembly notch 250, and the two sides of the bottom of the pallet slide and adapt to the end cross rollers 26. After sliding the forks a certain distance, they slide onto the long cross rollers. The opening structure formed on the front side of the two vertical roller frames 24 facilitates the insertion of the forks.

[0045] Preferably, a synchronous chain 261 is provided between the ends of two adjacent sets of short horizontal rollers 26, and a servo motor 262 for driving the end of any short horizontal roller 26 is fixed on one side of the roller frame 22.

[0046] Preferably, the end of the short horizontal roller 26 is formed with a mounting shaft 263, and two sets of sprockets 264 are fixed on the mounting shaft 263.

[0047] After the forks transport multiple pallets, since the forks do not have a pushing effect, a servo motor 262 is installed at the end of the short horizontal roller 26 to facilitate pushing the pallet carrying the multi-layer motor wheels, so that it can be transported to the required area, thereby facilitating subsequent gripping and assembly.

[0048] Preferably, sensors 4 are provided at the front edge of the top of the placement rack 20, above the middle of the roller rack 21, and at the top of the end of the roller rack 21.

[0049] In the above structure, the sensor on the placement rack 20 can detect whether the multi-layer pallets are stacked neatly; the two sensors on the roller rack 21 are used to detect whether the forks are feeding correctly and whether the goods have been transported to the end.

[0050] Preferably, the rear end of the idler frame 21 is provided with a baffle 28 that is higher than the horizontal roller 23. The design of the baffle 28 further restricts the degree of freedom of pallet displacement and reduces the risk of material falling.

[0051] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
