[0001] This utility model relates to the field of automobile production technology, specifically to a bolt storage device for a production line. Background Technology

[0002] During the multi-model mixed production process on the final assembly line, the use of different screws for different car models during the assembly of parts is due to the mixed material delivery of materials. As this is a mixed production line, operators need to be able to accurately pick the correct bolts according to different car models.

[0003] However, due to inconsistencies in the design materials and schemes of vehicle models, employees may use the wrong screws. Even when the wrong screws are tightened, the torque may appear normal. It is only discovered that the wrong screws were used during cost verification or after-sales issues. Existing error prevention technologies can only monitor torque, angle, and tightening curves, and cannot effectively prevent employees from using the correct screws. Therefore, a bolt storage device for production lines is provided to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a bolt storage device for production lines, which solves the problem of incorrect screw assembly on existing mixed-line automotive production lines.

The industrial computer captures the position signal of the worker picking up the bolt through the monitoring unit, then judges whether the bolt has been picked up correctly by comparing it with the position of the indicator light, and finally outputs a judgment signal.

[0006] Preferably, the judgment signal includes an audio signal and / or an image signal emitted by an industrial computer.

[0007] Preferably, the storage box is placed on the shelf with its front end tilted downwards, so that the bolts in the storage box naturally accumulate at the front end of the storage box under the action of gravity, thereby making it easy to retrieve.

[0008] Preferably, the placement rack is fixedly provided with multiple longitudinal baffles, the front ends of which are inclined downwards, so that multiple inclined placement positions are formed between the multiple longitudinal baffles, and the storage box is placed in the inclined placement position.

[0009] Preferably, the side of the longitudinal stop bar is integrally formed with a supporting protrusion, and the two sides of the storage box are integrally formed with anti-detachment protrusions, the anti-detachment protrusions abutting against the top of the supporting protrusion.

[0010] Preferably, the end of the inclined placement station is open, so that the storage box can slide along the support protrusion to enter or exit the inclined placement station, and a handle is fixedly provided on the back of the storage box.

[0011] Preferably, a vertical rod is fixedly connected to the end of the longitudinal stop bar, the monitoring unit is fixedly installed on the vertical rod, a horizontal rod is fixedly connected to the front end of the longitudinal stop bar, and the indicator light is fixedly installed on the horizontal rod.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0020] This utility model discloses a bolt storage device for a production line, according to the attached... Figure 1 To be continued Figure 5 As shown, it includes a placement rack 1 and multiple storage boxes 2 detachably mounted on the placement rack 1. The placement rack 1 is equipped with a retrieval prompting mechanism, which includes: The indicator light 32 corresponds to one of the multiple storage boxes 2. The corresponding indicator light 32 is lit to prompt the worker to take the bolt from the corresponding storage box 2. The monitoring unit 33 is fixedly mounted on the placement frame 1 and is used to monitor the position of the bolts picked up by the worker. Industrial computer 31 is connected to indicator light 32 and monitoring unit 33. Industrial computer 31 captures the position signal of the worker picking up the bolt through monitoring unit 33, and then judges whether the correct bolt has been picked up by comparing it with the position of indicator light 32. Finally, it outputs a judgment signal. Industrial computer 31 communicates with the entire production line control center so that when a frame of a certain model is transported on the production line, it automatically outputs the corresponding model information and the bolt type information to be assembled to industrial computer 31 at that position.

[0021] The judgment signals include sound signals and / or image signals emitted by the industrial computer 31. The industrial computer 31 can issue prompts such as "Incorrect pick-up" and "Correct pick-up" through sound, or display "Correct" and "Incorrect" on the screen of the industrial computer 31 or flash them to provide prompts.

[0022] The storage box 2 is placed on the placement rack 1 with its front end tilted downwards, so that the bolts in the storage box 2 will naturally accumulate at the front end of the storage box 2 under the action of gravity, making it easy to pick up. Multiple vertical baffles 12 are fixedly installed on the placement rack 1, with the front ends of the vertical baffles 12 tilted downwards, so that multiple tilted placement stations 16 are formed between the multiple vertical baffles 12. The storage box 2 is placed in the tilted placement station 16. The side of the vertical baffle 12 is integrally formed with a support protrusion 14, and the two sides of the storage box 2 are integrally formed with anti-detachment protrusions 23, which abut against the top of the support protrusion 14. The end of the tilted placement station 16 is open, so that the storage box 2 can slide along the support protrusion 14 to enter or move out of the tilted placement station 16. A handle 22 is fixedly installed on the back of the storage box 2, so that the storage box 2 can be pulled out from the back of the placement rack 1 for easy addition of bolts. At the same time, its tilted front end can make the bolts automatically accumulate at the front end for easy picking up.

[0023] A vertical rod 13 is fixedly connected to the end of the longitudinal stop bar 12, and the monitoring unit 33 is fixedly installed on the vertical rod 13. A horizontal rod 15 is fixedly connected to the front end of the longitudinal stop bar 12, and an indicator light 32 is fixedly installed on the horizontal rod 15 to provide a prompt from the front end, making it easy for workers to observe the corresponding indicator light 32 when picking up bolts.

[0024] The monitoring unit 33 includes a mounting base 331 fixedly mounted on the vertical rod 13. The front sides of the mounting base 331 are provided with mounting surfaces 333. A detection camera 332 is mounted on the mounting surfaces 333. The mounting surfaces 333 are inclined so that the two sets of detection cameras 332 are respectively facing the front ends of the two adjacent sets of storage boxes 2. This allows only one set of mounting base 331 to be used to install between two adjacent storage boxes, reducing installation costs. Furthermore, the detection camera 332 is located on the vertical rod 13 and is obliquely positioned to monitor the end of the storage box 2, thus avoiding obstruction when the storage box 2 is pulled out or inserted into the placement rack 1.

[0025] Working principle: In use, multiple storage boxes 2 contain different types of bolts. The storage boxes 2 are then tilted and inserted into the placement frame 1, so that the front end of the storage box 2 tilts downward, making it easier to pick up the bolts. When a car frame of a corresponding model is delivered to the production line, the corresponding model information is transmitted to the industrial computer 31. At this time, the industrial computer 31 obtains the required bolt type based on the model information, and then controls the corresponding indicator light 32 to light up according to the placement position of the corresponding bolt type. At this time, the operator picks up the corresponding bolt according to the prompt. While the operator is picking up the bolt, the detection camera 332 monitors the position of multiple storage boxes 2 in real time. Based on the operator's picking action, it judges whether the bolt picked up corresponds to the actual bolt that needs to be picked up, and outputs a correct or incorrect judgment signal based on the judgment result. In this way, during the bolt picking process, it can prompt the operator to pick up the correct bolt, and perform a secondary judgment after picking up the bolt, thereby preventing the problem of picking up the wrong bolt.
