DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0029] In the description of the embodiments of the present invention, it should be noted that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limitations on the embodiments of the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0030] In the description of the embodiments of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0031] In the embodiments of the present invention, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0032] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the embodiment of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0033] In the related art, due to the inevitable errors in the flatness of the mounting table, the assembly workpiece and the thread length of the screws, the simultaneous tightening of multiple screws is prone to uneven force during the locking process, which may cause a certain assembly to deflect, causing other assemblies to be subjected to additional stress and increasing the probability of damage to the assembly.

[0034] For example, the assembly of traditional CPU coolers requires manual operation. A CPU cooler needs to be locked with 4 screws. Manual operation can only lock the screws one by one, which is inefficient. In addition, the force is uneven during the locking process, which can easily cause the cooler to tilt, causing the CPU to be subjected to additional stress, increasing the probability of CPU damage.

[0035] In the related art, there is a synchronous screw locking device that can tighten multiple screws synchronously, solving the problem of low efficiency of manual screw locking.

[0036] However, the problem of uneven force on the screws when multiple screws are automatically tightened has not been effectively solved.

[0037] In view of this, the present invention provides an automatic screw locking device and an automatic assembly system to solve the problem of uneven force on the screws that occurs when a plurality of screws are automatically locked in the prior art.

By setting the same torque for the plurality of rotating driving members 132 of the plurality of screw locking modules 130, it is ensured that the plurality of screw locking modules 130 use the same torque to lock the plurality of screws, thereby ensuring that the force on the plurality of screws is uniform.
