[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0025] like Figure 1 As shown, the present invention provides a multi-mode rotating pallet device for automobile assembly, including: a pallet unit 1, a base unit 2, a locking unit 3 and a magnetic component 4. The pallet unit 1 has a placement space, and the pallet unit 1 is rotatably arranged on the base unit 2. The base unit 2 has a plurality of locking holes 20 to cooperate with the lock to lock the pallet unit 1. The locking unit 3 is hinged on the pallet unit 1, and part of its structure passes through the pallet unit 1 and can extend into the locking hole 20. The magnetic component 4 is arranged on the locking unit 3, and is close to the locking hole 20, so that when part of the structure of the locking unit 3 enters the locking hole 20, the magnetic component 4 is adsorbed on the base unit 2 to prevent the pallet unit 1 from rotating, and when an external force pushes the pallet unit 1 to rotate, the locking unit 3 can be disengaged from the locking hole 20 until it enters the next locking hole 20. When part of the structure of the locking unit 3 is away from the locking hole 20 and the magnetic component 4 is adsorbed on the pallet unit 1, the pallet unit 1 can rotate 360° relative to the base unit 2. By combining the locking unit 3 and the magnetic element 4, the different positions of the locking unit 3 can be adjusted according to the different requirements of the assembly for the assembly position. That is, when the locking unit 3 is driven to rotate through the structure of the tray unit 1 and approach the tray unit 1 and the magnetic element 4 is adsorbed on the tray unit 1, the tray unit 1 can rotate 360 ​​degrees freely. When the locking unit 3 is driven to rotate and approach the base unit 2 until the magnetic element 4 is adsorbed on the base unit 2, the tray unit 1 stops moving, that is, the tray unit 1 is locked. When an external force pushes the tray unit 1 to rotate, the locking unit 3 can be disengaged from the locking hole 20 and enter the next locking hole 20. This achieves that the tray unit 1 can be driven to rotate by an external force even in the locked state. The tray unit 1 can be rotated only when the external force is greater than the magnetic force, thereby achieving one-way rotation and locking, meeting the requirements of different assembly positions, and ultimately achieving the purpose of auxiliary assembly, improving the convenience and efficiency of assembly operations, and achieving the purpose of good ergonomics. Optionally, the magnetic element is a magnet. Of course, in other cases, the magnet can also be replaced by an energized coil.

[0026] In one embodiment, the locking unit 3 includes a lock handle portion 31 and a lock head portion 32 connected to each other, the connection between the lock handle portion 31 and the lock head portion 32 is hinged on the tray unit 1, and the lock head portion 32 is located between the tray unit 1 and the base unit 2, and the magnetic component 4 is arranged on the lock head portion 32. It should be noted that when the locking portion 32 approaches the tray unit 1 and the magnetic component 4 is adsorbed on the tray unit 1, the tray unit 1 rotates 360° relative to the base unit 2. When the locking portion 32 enters the locking hole 20, the magnetic component 4 is adsorbed on the base unit 2, thereby locking the tray unit 1. In the absence of external force, the tray unit 1 will not rotate. When the external force pushes the tray unit 1 to rotate, the locking portion 32 can be disengaged from the locking hole 20 until it enters the next locking hole 20, thus achieving one-way rotation. This one-way rotation is carried out under the push of an external force and can only rotate at a fixed angle. Each rotation requires external force to drive the tray unit 1. As long as the external force is greater than the magnetic force of adsorption, the tray unit 1 can be moved. When the external force is removed, the tray unit 1 will not rotate under the magnetic component 4. The requirements of assembly positions at different positions or angles are met, and the purpose of auxiliary assembly is ultimately achieved, thereby improving the convenience and efficiency of assembly operations.

[0027] In one embodiment, the locking portion 32 is provided with a snap-fitting structure, which can be snapped onto the edge of the locking hole 20 to limit the position of the locking portion 32 within the locking hole 20, and a spacing is provided between the snap-fitting structure within the locking hole 20 and the locking hole 20, so that the magnetic element 4 can be adsorbed on the base unit 2. When the tray unit 1 is driven to rotate, the snap-fitting structure can smoothly slide out of the locking hole 20 until the snap-fitting structure enters the next locking hole 20. By limiting the position of the locking portion 32 within the locking hole 20 through the snap-fitting structure on the locking portion 32, and by adsorbing the magnetic element 4 near the locking hole 20, the tray unit 1 can be prevented from rotating. However, the tray unit 1 can be rotated only under the action of an external force, thereby eliminating the need for additional operations and avoiding complicated operations, thereby improving work efficiency.

[0028] In one embodiment, the surface of the snap-fit ​​structure in the locking hole 20 is an inclined surface to facilitate smooth sliding out of the locking hole 20. Since the surface of the snap-fit ​​structure is an inclined surface, when an external force pushes the tray unit 1 to rotate, the snap-fit ​​structure on the lock portion 32 can smoothly come out of the locking hole 20, thereby eliminating the need to re-unlock. It only requires that the external force is greater than the magnetic force, thereby driving the tray unit 1 to rotate even when locked. That is, there is no need to operate the lock handle 31 to drive the lock portion 32 and the magnetic element 4 thereon to leave the base unit 2, thereby unlocking the tray unit 1, thereby improving the convenience of operation.

[0029] In one embodiment, the tray unit 1 includes a tray portion 12 and a rotating portion 11 that are rotatably connected. The rotating portion 11 is provided on the base unit 2, and the locking unit 3 is hingedly connected to the tray portion 12, with a portion of its structure passing through the tray portion 12. The rotating portion 11 enables the tray portion 12 to rotate. The locking unit 3 is hingedly connected to the tray portion 12, that is, the lock handle 31 on the locking unit 3 is hingedly connected to the tray portion 12. By controlling the lock handle 31 to rotate, the lock head portion 32 connected thereto is driven to rotate, so that the magnetic element on the lock head portion 32 can also move therewith, so that it can be adsorbed on both the tray portion 12 and the base unit 2.

[0030] In one embodiment, the rotating portion 11 includes a first sleeve 111 and a rotating shaft 112 connected to each other. The first sleeve 111 is disposed on the tray portion 12, and the rotating shaft 112 is rotatably disposed on the base unit 2. The rotating shaft 112 and the first sleeve 111 are used to realize the rotation of the tray portion 12. Of course, in addition to this rotation method, other rotation methods may also be used, such as spiral rotation or motor rotation.

[0031] In one embodiment, the tray portion 12 includes a tray 121 and a fixing seat 122. The tray 121 has an opening 120. The fixing seat 122 is disposed near the opening 120. The fixing seat 122 is disposed on the tray 121, and the locking unit 3 partially passes through the opening 120 and is rotatably disposed on the fixing seat 122. Optionally, the fixing seat 122 is two identical raised structures, which are spaced apart and disposed on either side of the opening 120. The locking handle 31 on the locking unit 3 is connected to the two raised structures via a shaft, thereby enabling the locking handle 31 to rotate.

[0032] In one embodiment, the base unit 2 includes a base 21 and a bearing 22. The rotating shaft on the tray 121 is disposed in the bearing 22, and the bearing 22 is disposed on the base 21. Optionally, a plurality of locking holes 20 are evenly disposed on the base 21.

[0033] In one embodiment, the plurality of locking holes 20 are four or six. The four or six locking holes 20 are evenly distributed on the tray 121. The provision of four or six locking holes 20 allows the tray 121 to be locked and driven to rotate, allowing the locking portion 32 to slide out of one locking hole 20 and into the next locking hole 20. In the absence of external force driving the tray 121 to rotate, the locking holes 20 can also restrict the rotation of the tray 121 to a certain extent. This allows each hole to restrict the rotation of the tray 121, thus enabling the assembly of the tray 121 in various directions.

[0034] In one embodiment, when there are four locking holes 20, the four locking holes 20 are arranged at 90 degrees to each other on the base unit 2, and when there are six locking holes 20, the six locking holes 20 are arranged at 60 degrees to each other on the base unit 2. By having the four locking holes 20 arranged at 90 degrees and the six locking holes 20 arranged at 60 degrees to each other, the tray 121 can rotate in one direction at multiple angles, that is, when in the locked state, the tray 121 rotates from one locking hole 20 to the next.

[0035] The present invention realizes the function of rotating the tray 121 by fixing the position of the locking unit 3 by adsorbing magnetic parts according to the requirements of the subpackaging operation.

[0036] The present invention has three modes, which are as follows:

[0037] like Figure 3 As shown, the first mode is a free rotation mode: by adjusting the locking unit 3, the magnetic element 4 is adsorbed on the tray 121 of the tray unit 1. At this time, the tray 121 is free to rotate through the rotating shaft on the rotating part 11, and the tray 121 can be rotated 360°;

[0038] like Figure 2 As shown, the second mode is the locking mode: by adjusting the lock handle 31 on the locking unit 3, the lock head 32 connected to the lock handle 31 is locked into the locking hole 20 on the base 21. At this time, the magnetic element 4 is adsorbed on the base 21. The tray 121 is stationary relative to the base 21, and the locked state is achieved;

[0039] One-way rotation (multi-angle) state: When the tray 121 is in the locked state, the locking unit 3 moves out of the locking hole 20 on the base 21 by rotating the tray 121 unidirectionally clockwise. When the locking unit 3 is rotated to a certain angle, the locking unit 3 falls into the next locking hole 20 on the base 21, thereby achieving one-way multi-angle rotation of the tray 121.

[0040] According to the above technical solution, the application of a multi-mode rotating tray 121 device is provided, which has a simple structure, is lightweight, and is easy to operate. It can meet the auxiliary assembly needs of the assembly position, and at the same time greatly improves ergonomics and production efficiency. The multi-mode rotating tray 121 device of the present invention should have the advantages of low development and manufacturing cost, and low subsequent maintenance cost.

[0041] According to the different requirements of the assembly for the assembly position, the free rotation, unidirectional rotation (multi-angle) and locking of the tray 121 are achieved by adjusting the different positions of the locking unit 3, meeting the requirements of different assembly positions, and ultimately achieving the purpose of auxiliary assembly, improving the convenience of assembly operations and improving the efficiency of assembly operations, and achieving the purpose of good ergonomics.

[0042] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
