[0001] DRIVER-INTEGRATED CONTROL DEVICE WITH ERGONOMIC AND EFFICIENT SCANNING SYSTEM

[0002] TECHNICAL FIELD

[0003] The invention relates to a torque control device for use particularly with impact wrenches, into which a barcode scanner is integrated for automatic torque adjustment based on fastener information.

[0004] PRIOR ART

[0005] In order for bolted connections to be used safely and also not to damage the parts they hold together in the place of use, there exists a specific and calculable safe torque value unique to that connection. One newton-meter of torque is generated when a one-newton force acts perpendicularly at a distance of one meter from a pivot point. The control of tightened bolts is based on marking the nut portion, the base material, and the nut, and checking it via a torque meter adjusted to the desired torque values from the nut. With the advancement of technology, manual controls have begun to be replaced by digital controls. In the known technique, it is aimed to detect whether a bolt is fastened with the correct amount of torque and prevent over- or under-tightening through a component called an adaptive torque module added to a cordless impact wrench. In these devices, the scanner module that reads the information belonging to the bolt is placed between the battery and the driver body. Although it allows the scanner module to receive the necessary energy directly from the battery, it has the disadvantages listed below: The additional weight of the scanner module disrupts the center of gravity of the tool. This situation leads to discomfort during use and causes extra fatigue for the user. Therefore, the efficient working time is shortened. To scan a barcode containing the torque information of the bolt before operation, the scanner placed between the battery and the driver forces the tool to be held in an uncomfortable position for the operator. The difficulty in positioning due to this configuration makes usage harder. The difficulty in positioning increases further due to the unbalanced center of gravity. The devices of the known technique, used to eliminate manual requirements, cannot offer a complete solution for users due to the stated technical problems. BRIEF DESCRIPTION OF THE INVENTION

[0006] The invention has been developed to solve the technical problems defined in the known technique, offering a balanced center of gravity, providing comfort to the user, increasing working efficiency and duration, and enabling the barcode, QR code, or similar marking required to be scanned before operation, to obtain the anchoring information of the bolt, to be read practically, without positioning difficulty, via a scanner positioned at the upper part of a cordless impact wrench with a driver-integrated torque control system possessing ergonomic and scanning efficiency features.

[0016] DETAILED DESCRIPTION OF THE INVENTION

[0017] The invention is characterized by: an impact wrench (1 ) with a battery (2) located in its lower section, a scanner (3) positioned at the top part of the impact wrench (1 ), and software (4) that automatically adjusts the impact wrench (1 ) according to the information read by the scanner (3).

[0018] The scanner (3), by being positioned on the upper part of the impact wrench (1 ), prevents the weight from concentrating in the grip area by merging its weight with the battery (2), which significantly affects the center of gravity. Thus, the balancing of the weight to be accumulated in the handle part of the impact wrench (1 ) together with the battery’s (2) weight, and the planar centering of the center of gravity, enables comfortable usage. Since, the user does not need to constantly exert effort to balance an unbalanced impact wrench (1 ), working time and efficiency are increased. Because the scanner (3) is located on the upper part of the impact wrench (1 ), barcodes, QR codes, or similar markings containing the required torque information for the fastening element can be positioned accordingly and scanned. In the known technique, technical problems caused by the difficulty of positioning and the resulting scanning issues due to the scanner being located above the battery and below the grip section have been completely eliminated. Additionally, when the scanner (3) is positioned beneath the grip section, it is at a much higher risk of impact. This is because the user's attention is generally focused on the part of the device that tightens the fastening element, making it more likely for the grip area to collide with surrounding objects. This situation may render the scanner (3) inoperative. In the impact wrench (1 ) with an integrated torque control system featuring ergonomics and scanning efficiency, which is the subject of the invention, the scanner (3) is located in the upper part of the device where the user's attention is naturally focused. Therefore, it is unlikely that environmental elements capable of striking and damaging this area will go unnoticed by the user. As a result, the scanner (3), which is the most essential component for the system's operation, is optimally protected under harsh working conditions. Furthermore, the data read by the scanner (3) is processed to automatically adjust the torque value of the impact wrench (1 ) according to the requirements of the fastening element.
