Description

Technical Field

[0001] This utility model relates to the field of screw driving machine technology, specifically an automatic screw driving machine with a protective cover. Background Technology

[0002] An automatic screw fastening machine is a device used in industrial production to automatically tighten screws. It can effectively improve production efficiency and ensure assembly quality. The entire process, from screw feeding and positioning to tightening, is completed automatically. It can be seamlessly integrated with other automated production lines and can accurately tighten screws at different positions according to preset programs and parameters, greatly improving production efficiency and reducing manual intervention.

[0003] With the continuous development of industrial automation, the demand for automatic screw-driving machines in various industries is increasing, and the requirements for their functions and performance are also getting higher and higher. Screw-driving operations are usually done manually, which is inefficient and cannot effectively guarantee the fit between the screw and the screw hole, potentially causing tooth breakage or incomplete installation. Without a protective cover, the screwdriver may leave scratches or other damage on the workpiece surface, affecting the product's appearance and quality. A protective cover can shield the product, ensuring it is not accidentally damaged during screw-driving. Dust and debris from the external environment may enter the automatic screw-driving machine, affecting the normal operation of its transmission components and feeding mechanism, accelerating equipment wear. The protective cover can prevent dust and debris from entering, extending the equipment's service life.

[0004] According to the search, Chinese Patent Publication No. CN201520059558.7 discloses an automatic screw-driving machine; it includes a screw-driving machine housing, a worktable, a stepper motor, a PLC control panel and a working system. The screw-driving machine housing is connected to the worktable and the PLC control panel by screws. The stepper motor is connected to the PLC control panel by wires. The PLC control panel is connected to the working system by a data cable.

[0005] When the aforementioned patented device is used to fix a product with screws, the product is placed on a workbench. This method cannot effectively fix the product, which may cause the product to shift during screwing, resulting in the screws not fitting properly with the product and affecting the quality of screwing. Furthermore, the device in the aforementioned patent cannot effectively guarantee the positioning of the screws, which may result in the screws being positioned outside the screw holes.

[0032] The screw feeding assembly 5 is fixedly installed on the bottom of the electrical control box 2, and the electrical control box 2 is also provided with a fixing assembly 3; the fixing assembly 3 includes a slide rail 30; the slide rail 30 is fixedly installed with the electrical control box 2; a sliding plate 34 is slidably installed on the slide rail 30; the bottom of the sliding plate 34 is installed in conjunction with a rodless cylinder.

[0033] By adopting the above technical solution, when in use, the staff places the product that needs to be fixed into the placement box 31, flips the cover plate 32 on the top of the upright plate 35, so that the buckle 33 provided on the inner side of the cover plate 32 engages with the slide plate 34, effectively ensuring the stability of the cover plate 32 in fixing the product. Then, the slide plate 34 is moved along the slide rail 30 by the electrical control box 2 to move the product that needs to be screwed into place.

[0034] In this embodiment, a placement box 31 is fixedly installed on the skateboard 34; two placement slots are provided on the top of the placement box 31; a vertical plate 35 is provided on one side of the placement box 31; the vertical plate 35 is fixedly installed on the skateboard 34.

[0035] In this embodiment, the end of the upright plate 35 away from the slide plate 34 is hinged and fixed to the cover plate 32; the cover plate 32 has a plurality of holes for easy screw penetration; a buckle 33 is provided on the inner side of the end of the cover plate 32 away from the upright plate 35; the buckle 33 and the slide plate 34 are detachably installed.

[0036] By adopting the above technical solution, when screwing, the screw is transmitted to the gap 57 between the rotating plate 56 and the mating plate 59 by the transmission mechanism inside the housing 50. The rotating plate 56 is rotated by the rotating cylinder 58, so that the screws are fed one by one, avoiding the situation of screws piling up.

[0037] Furthermore, the electrical control box 2 is also equipped with a drive assembly 4; the drive assembly 4 includes two symmetrical support plates 40; a transverse slide 41 is fixedly installed on the top of the support plates 40; a lead screw is provided inside the transverse slide 41, one end of the lead screw is fixedly installed with a motor 42; the lead screw is installed in conjunction with an L-shaped slide 43; an electric push cylinder 45 is fixedly installed on the inner side of the bottom of the L-shaped slide 43.

[0039] By adopting the above technical solution, the control of the motor 42 by the control box 2 enables the lead screw to drive the L-shaped slide 43 to move along the transverse slide 41, thereby moving the structure at the bottom of the L-shaped slide 43 to the top of the rotating plate 56 or the cover plate 32. The electric push cylinder 45 drives the fixing plate 46 and the L-shaped fixing plate 47 to move downward, so that the negative pressure adsorption head 48 can effectively adsorb the screw in the notch 57 in cooperation with the air tube 49. After adsorption is completed, the electric push cylinder 45 moves upward, and the negative pressure adsorption head 48 is moved to the top of the cover plate 32 through the L-shaped slide 43.

[0041] By adopting the above technical solution, when the bottom of the negative pressure adsorption head 48 coincides with the hole opened on the cover plate 32, the electric push cylinder 45 descends again. When the bottom of the negative pressure adsorption head 48 contacts the top of the cover plate 32, the electric push cylinder 45 stops. Then, the control box 2 controls the cylinder 44, so that the cylinder rod of the cylinder 44 installs the screw adsorbed by the negative pressure adsorption head 48 into the screw hole opened on the product. By repeating the operation, the screws in different positions of the product can be installed.

[0042] The working principle of this utility model is as follows: When in use, the staff places the product that needs to be fixed into the placement box 31, flips the cover plate 32 on the top of the upright plate 35, so that the buckle 33 provided on the inner side of the cover plate 32 engages with the slide plate 34, effectively ensuring the stability of the cover plate 32 in fixing the product. Then, the slide plate 34 is moved along the slide rail 30 through the electrical control box 2 to move the product that needs to be screwed into place.

[0043] When screwing in screws, the screws are transported to the notch 57 between the rotating plate 56 and the mating plate 59 by the transmission mechanism inside the housing 50. The rotating plate 56 is rotated by the rotating cylinder 58, so that the screws are fed one by one and the screws are not piled up.

[0044] By controlling the motor 42 through the electrical control box 2, the lead screw drives the L-shaped slide 43 to move along the transverse slide 41, thereby moving the structure at the bottom of the L-shaped slide 43 to the top of the rotating plate 56 or the cover plate 32. The electric push cylinder 45 drives the fixed plate 46 and the L-shaped fixed plate 47 to move downward, so that the negative pressure adsorption head 48 can effectively adsorb the screw in the notch 57 in cooperation with the air tube 49. After adsorption is completed, the electric push cylinder 45 moves upward, and then moves the negative pressure adsorption head 48 to the top of the cover plate 32 through the L-shaped slide 43.

[0045] When the bottom of the negative pressure adsorption head 48 coincides with the hole opened on the cover plate 32, the electric push cylinder 45 descends again. When the bottom of the negative pressure adsorption head 48 contacts the top of the cover plate 32, the electric push cylinder 45 stops. Then, the control box 2 controls the cylinder 44, so that the cylinder rod of the cylinder 44 installs the screw adsorbed by the negative pressure adsorption head 48 into the screw hole opened on the product. By repeating the operation, screws in different positions on the product can be installed.
