Description

Technical Field

[0001] The utility model relates to the technical field of instrument panel production and processing equipment, in particular to an automatic screw driving device. Background Art

[0002] Plastic products are common structures in daily life and industrial production, such as instrument display panels. Some plastic shells are often fixed together by screws, which requires screwing on the plastic shell. For example, a fixing seat needs to be installed on the plastic shell of the instrument display panel to form a complete plastic shell structure. Nowadays, screwing is mostly done manually. In order to reduce the labor intensity of workers, workers only use electric screwdrivers to screw in screws. The manual screwing method has the following disadvantages: (1) waste of labor costs; (2) torque cannot be guaranteed, that is, the force used to tighten the screws cannot be guaranteed to be consistent; (3) the number of screws may not be screwed in or may be insufficient, affecting product quality.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0023] like Figures 1 to 3 The automatic screw driving device shown includes a base 1, a bracket 2, a transmission device 3, and a rotating mechanism 4. The bracket 2 is fixed on the left and right sides of the base 1. The bracket 2 includes a crossbeam 22 and two side panels 21. The transmission device 3 includes a first transmission mechanism 31, a second transmission mechanism 32 and a third transmission mechanism 33. The first transmission mechanism 31 is connected to the crossbeam 22, the second transmission mechanism 32 is located on the side of the first transmission mechanism 31, the third transmission mechanism 33 is located on the upper surface of the base 1, and the rotating mechanism 4 is located on the surface of the third transmission mechanism 33. The rotating mechanism 4 includes a detachable screwdriver 41, a motor 42 and a shockproof ring 43. The motor 42 is connected to the screwdriver 41 up and down, and the shockproof ring 43 is arranged at one end of the tool head close to the screwdriver 41.

[0024] The implementation process of the utility model is to place the instrument panel to be installed on the upper part of the third slider 332, and position the instrument panel through four positioning blocks 333. At this time, the first transmission mechanism 31 and the third transmission mechanism 33 begin to adjust their positions and move under the action of the hydraulic cylinder. When the discharge port 5 reaches the corresponding position, the screw automatically falls into the screw hole. At this time, the second transmission mechanism 32 begins to move downward until the blade of the screwdriver 41 contacts the screw. The motor 42 starts to work and drives the screwdriver 41 to rotate until the screw is screwed into the instrument panel.

[0025] In the present invention, the first transmission mechanism 31 includes a first slide plate 312 and two first slide rails 311. The first slide plate 312 is arranged in an L shape. The two first slide rails 311 are respectively arranged on the upper surface of the beam 22 and the side facing the workbench, so that the first slide rail 311 can withstand forces from different directions, thereby enhancing the stability of the entire mechanism. The first slide rail 311 is fixed to the beam 22 by bolts, and the first slide plate 312 is connected to the first slide rail 311 for sliding left and right. This connection method is simple and firm, and is easy to install and maintain. A feeding device 5 in the shape of an inclined funnel is provided on the side of the first slide plate 312. The feeding device 5 is hollow inside, and the position of the discharge port 51 is located directly below the screwdriver 41, which is convenient for feeding screws into the screw holes, saving the cost of manually adding screws, improving installation efficiency, and avoiding the situation of missing or not inserting screws due to manual screw placement.

[0026] In the present embodiment, the second transmission mechanism 32 comprises a second slide rail 321, a second slide plate 322 and an extension plate 323. The second slide plate 322 is slidably connected to the second slide rail 321 up and down. The extension plate 323 is fixed to the lower part of the second slide plate 322 by bolts, which ensures the firmness of the connection and enhances the structural strength of the second slide plate 322. A fixing block 324 is arranged on the upper side of the extension plate 323. The fixing block 324 is provided with a circular through hole 3241 which is communicated with each other from top to bottom. The lower side is fixedly connected to the anti-vibration ring 43. The motor 42 is arranged above the fixing block 324. The screwdriver 41 is connected to the motor 42 and passes through the circular through hole 3241 and extends to the lower part. Passing through the anti-vibration ring 43 not only provides a passage for the screwdriver 41 to pass through, but also facilitates the installation of the motor 42, so that the motor 42 can be stably placed above the fixing block 324 and connected to the lower part through the screwdriver 41. The anti-vibration ring 43 serves as a buffer device, which can effectively absorb and mitigate the vibration and impact caused by the movement, and protect the entire transmission mechanism from damage.

[0027] In a preferred embodiment of the utility model, the third transmission mechanism 33 includes a third slide rail 331 and a third slide plate 332. The third slide plate 332 slides radially on the third slide rail 331. The upper part of the third slide plate 332 is provided with a centrally symmetrical L-shaped positioning block 333. The radial sliding of the third slide plate 332 on the third slide rail 331 cooperates with the centrally symmetrical L-shaped positioning block 333 to achieve more precise positioning. The transmission device 3 is powered by a hydraulic cylinder to drive the transmission mechanism 3 to move.

[0028] Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the description are only for explaining the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which are within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
