[0037] The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0038] This embodiment relates to an anti-mistake device installed using bolts. In terms of the overall structure, as shown in Figure 1 , Figure 2 , it includes an industrial control computer 1, a barcode scanner 2 connected to the industrial control computer 1, and a bolt box 3.

[0039] Among them, the bolt box 3 includes a plurality of storage boxes 302 for storing different types of bolts, and a frame 301 for installing each storage box 302. A top cover 303 that can be opened and closed is provided at the top of the storage box 302 of the driving mechanism 304, and a plurality of driving mechanisms 304 corresponding to each top cover 303 are provided on the frame 301. The movable end of the driving mechanism 304 is connected to the top cover 303, and each driving mechanism 304 is connected to the industrial control computer 1. At the same time, the barcode scanner 2 is used to scan the two-dimensional code on the product 6 to be assembled, and send the bolt type, bolt quantity, installation position, and torque value corresponding to the two-dimensional code to the industrial control computer 1.

[0040] When the barcode scanner 2 scans the two-dimensional code on the product 6 to be assembled, and the bolt type, bolt quantity, installation position, and torque value corresponding to the two-dimensional code are displayed on the display screen 4 through the transmission of the industrial control computer 1, the industrial control computer 1 can drive the corresponding driving mechanism 304 according to the bolt type, so that the driving mechanism 304 opens the top cover 303 on the corresponding storage box 302.

[0041] Subsequently, during the operation, the information on the display screen 4 can be viewed, and the corresponding bolts can be taken out from the storage box 302 and installed at the corresponding positions of the product to be assembled. The information display is the prior art and will not be elaborated here.

[0042] As described above, by setting the industrial control computer 1 and the barcode scanner 2, the bolt type, quantity, and installation position required for the product 6 to be assembled can be obtained by scanning the two-dimensional code with the barcode scanner 2 and displayed on the display screen 4 for viewing during the operation. And by opening and closing the storage box 302 through the industrial control computer 1, it is possible to avoid taking the wrong bolts during the operation, thereby avoiding the wrong installation or omission of bolts due to negligence during the operation. The acquisition of the bolt type, quantity, and installation position by scanning the two-dimensional code with the barcode scanner 2 is the prior art and will not be elaborated here.

[0043] Based on the above overall introduction, specifically, continuing to combine Figure 1 and Figure 2 shown, the driving mechanism 304 of this embodiment is one of an electric pull rod, a cylinder, and a hydraulic cylinder. Of course, other conventional driving mechanisms well-known to those skilled in the art can also be used, as long as it has a movable end with linear motion. At the same time, the top cover 303 is a flip cover 303a hinged on the storage box 302, and the movable end of the driving mechanism 304 is hinged to the flip cover 303a. When the movable end of the driving mechanism 304 moves back and forth, it can pull the flip cover 303a to flip, so as to realize the opening and closing of the flip cover 303a.

[0044] Or as another implementation form, Figure 3 As shown, the top cover 303 of this embodiment is a push-pull cover 303b slidably arranged on the top of the storage box 302, and the driving mechanism 304 can drive the push-pull cover 303b to slide back and forth to realize the opening and closing of the push-pull cover 303b, thereby facilitating the opening and closing of the storage box 302 of this embodiment and making it convenient to take the bolts during operation.

[0045] In order to facilitate the taking of bolts from the bolt box 3 during operation, the storage boxes 302 of this embodiment are arranged in rows and columns on one side of the frame 301 along the height direction of the frame 301, and the storage boxes 302 between two adjacent rows are arranged in a stepped manner. By arranging the storage boxes 302 in a stepped manner, the bolt box 3 has a compact structure and is convenient for opening and closing the top cover 303. When the driving mechanism 304 opens the top cover 303, the opening and closing angle of the top cover 303 is large, which is convenient for taking bolts from the storage boxes 302 during operation and is convenient for taking the bolts.

[0046] In specific implementation, the frame 301 of the bolt box 3 of this embodiment is provided with two layers of eight storage boxes 302, which can store eight kinds of bolts. Of course, the number of storage boxes 302 on the bolt box 3 can be determined according to the types of bolts required for actual assembly. In addition, each storage box 302 of this embodiment is located at the upper part of the frame 301, so as to facilitate taking during operation, and the bottom of the frame 301 is provided with a storage space 307, which can store tools or other parts used for assembly.

[0047] In order to further facilitate the taking of bolts during operation, each storage box 302 of the present embodiment is tilted toward the outside of the frame 301. Through the tilted setting of the storage box 302, the opening on the top of the storage box 302 can be facing the operation. When the top cover 303 is opened, it is convenient to check the studs inside the storage box 302 during operation. At the same time, it is convenient to extend the hand or the execution end of the robot into the storage box 302 to take the bolts during operation, thereby facilitating the taking of the bolts.

[0048] In addition, a transparent observation window 305 is provided on the top cover 303 of this embodiment. When the top cover 303 is in a tubular state, the number of bolts in the storage box 302 can be directly viewed through the observation window 305 during operation. When the number of bolts is insufficient, it can be observed during operation and the corresponding bolts can be replenished in a timely manner. In addition, a label 306 is provided on the top cover 303 of this embodiment. Information such as the label number of the storage box 302 and the type of bolts corresponding to the storage box 302 can be marked on the label 306, so as to facilitate judging the type of bolts in the corresponding storage box 302 by observing the label 306 during operation, which is convenient for taking and replenishing bolts. In this embodiment, by setting the display screen 4, during operation, the type and number of bolts can be viewed on the display screen 4, and the corresponding type and number of bolts can be taken out from the corresponding storage box 302. However, relying solely on visual inspection during operation for the information of the type and number of bolts, there is still a situation where bolts may be taken more or less due to negligence during operation.

[0049] In order to ensure the accuracy of the number of bolts taken during operation, a detection sensor for detecting whether a bolt is taken out is provided on each storage box 302 of this embodiment to judge whether the corresponding number of bolts is taken out during operation. Specifically, the detection sensor of this embodiment includes an infrared transceiver and a weighing sensor connected to the industrial control computer 1.

[0050] Among them, the infrared transceiver includes an infrared emitter and an infrared receiver respectively arranged on two opposite sides of the inner wall of the storage box 302. When taking bolts during operation, the hand during operation will extend into the storage box 302 and block the infrared signal emitted by the infrared emitter to the infrared receiver. At this time, the industrial control computer 1 judges that the bolts in the storage box 302 are taken through the infrared transceiver. The weighing sensor is arranged between the storage box 302 and the frame 301, and the weighing sensor is used to weigh the weight of each bolt in the storage box 302. When the corresponding number of bolts is taken during operation, the weight of the storage box 302 and the bolts it contains will decrease. The weighing sensor can send the overall weight of the storage box 302 and the bolts in it after taking the bolts to the industrial control computer 1, and the industrial control computer 1 can judge whether the corresponding number of bolts is taken out during operation according to the weight reduction value. Thus, through the setting of the infrared transceiver and the weighing sensor, the industrial control computer 1 can judge whether the bolts are taken and whether the number taken is correct, thereby improving the accuracy of the number of bolts taken and avoiding missing bolts due to negligence during operation.

[0051] During specific implementation, if the number of bolts taken is greater than or less than the number of bolts required for the actual product to be assembled 6, the industrial control computer 1 can control the driving mechanism 304 to keep the top cover 303 open and display an alarm message on the display screen 4.

[0052] In this embodiment, the industrial control computer 1 of this embodiment is a PLC programmable logic controller. The PLC programmable logic controller is a conventional digital arithmetic controller with a microprocessor well-known to those skilled in the art and is used for automatic control. It can load control instructions into memory at any time for storage and execution. The PLC programmable logic controller consists of functional units such as a CPU, instruction and data memory, input / output interfaces, power supply, digital-to-analog conversion, etc. It uses a programmable memory to store instructions for performing operations such as logical operations, sequential control, timing, counting, and arithmetic operations internally. In this embodiment, the PLC programmable logic controller serving as the industrial control computer 1 is mainly used to read the two-dimensional code on the product 6 to be assembled, obtain and store information such as bolt type, bolt quantity, installation position, and torque value, display the above information on the display screen 4, and drive the driving mechanism 304 to act. Through the setting of the PLC programmable logic controller, the normal operation of the barcode scanner 2, the display screen 4, and each driving mechanism 304 is ensured, and the reliability of the bolt installation error prevention device in this embodiment is improved.

[0053] In addition, the bolt installation error prevention device of this embodiment further includes a torque wrench 5, and a torque sensor 501 is provided inside the torque wrench 5. The torque sensor 501 can measure the torque of the torque wrench 5 on the bolt in real time, and the torque sensor 501 can send the torque to the industrial control computer 1 in real time and display it on the display screen 4. Through the setting of the torque wrench 5 and the torque sensor 501 therein, the pre-tightening torque of the torque wrench 5 on the bolt can be detected in real time, ensuring the safe installation of each bolt and improving the installation effect of the bolt.

[0054] In addition, since the installation position of the bolt needs to be known by viewing the display screen 4 during operation, there is still a situation where the bolt installation position is misaligned due to negligence during operation. Therefore, in order to ensure the accuracy of the bolt installation position, a mobile positioning module 502 is provided inside the torque wrench 5 of this embodiment. The mobile positioning module 502 can detect and record the moving position of the torque wrench 5 in real time. When the torque wrench 5 coincides with the installation position of the bolt, the torque wrench 5 can be activated to fasten the bolt on the product 6 to be assembled. When the torque wrench 5 does not move to any installation position and a bolt is missed, the industrial control computer 1 alarms through the display screen 4, thereby improving the accuracy of the bolt installation position and preventing the wrong installation and omission of bolts. In specific implementation, the mobile positioning module 502 of this embodiment is a conventional mobile positioning module 502 well-known to those skilled in the art, such as a position sensor and an acceleration sensor, etc., as long as it can detect the position of the torque wrench 5 in the working station where the bolt installation error prevention device of this embodiment is located.

[0055] In summary, the anti-misassembly tooling for bolt installation in this embodiment can obtain the types, quantities, and installation positions of the bolts required for the product 6 to be assembled by scanning the QR code with the barcode scanner 2, and display them on the display screen 4 for viewing during operation. Moreover, by opening and closing the storage box 302 through the industrial control computer 1, it can prevent taking the wrong bolts during operation, thereby avoiding misassembly or missing installation of bolts due to negligence during operation, and has good practicability.

[0056] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
