[0049] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0050] Reference Figure 1~Figure 4 , the utility model proposes an automatic guide rod detection and screening device, including a first conveying device 2, which is arranged at one side of a bracket 1, and the first conveying device 2 is used to convey carbon blocks; a bell 6, which is slidably arranged relative to the bracket 1, and the bell 6 is used to clamp the top of the guide rod, and the sliding direction of the bell 6 is the same as the sliding direction of the first conveying device 2; a first guide rod clamp 3, which is slidably arranged on the bracket 1, and the sliding direction of the first guide rod clamp 3 is the same as the conveying direction of the first conveying device 2, and the first guide rod clamp 3 is used to clamp the guide rod; a first lifting platform 4, which is lifted and arranged at one side of the first conveying device 2, and the first conveying device 2 is used to convey carbon blocks to the first lifting platform 4, and the first lifting platform 4 is lifted and moved closer to or away from the first guide rod clamp 3; a laser detection device 5, which is arranged on the bracket 1, and the laser detection device 5 is located above the first conveying device 2, and the laser detection device 5 has a detection space, the first guide rod clamp 3 clamps the guide rod and slides through the detection space, and the laser detection device 5 is used to detect whether the guide rod steel claw is skewed.

[0051] In this embodiment, the first guide rod clamp 3 slides along the direction of the first conveying device 2 to stay above the first lifting platform 4. This design ensures the precise alignment of the guide rod and the carbon block. The rising action of the first lifting platform 4 enables the guide rod to be accurately inserted into the reserved hole of the carbon block to complete the preliminary assembly of the anode assembly. This process is simple and direct, reducing the complexity and errors of manual operation and improving the accuracy and efficiency of assembly. By adjusting the lifting height of the first lifting platform 4, the system can flexibly adapt to the production of anode assemblies of different sizes, showing good adaptability and flexibility, simplifying the adjustment process when changing product models, and reducing conversion costs.

[0052] The laser detection device 5 monitors the guide rod in real time to ensure the straightness and position correctness of the guide rod before assembly. The laser detection device 5 is located above the first conveying device 2. After the guide rod is detected by the laser detection device 5 and is qualified, it moves and stays above the first lifting platform 4, waiting for assembly. The laser detection device 5 is located above the first conveying device 2, which can not only detect the quality of the guide rod in advance, but also avoid interference with the first lifting platform 4. The laser scanning in the detection space can quickly identify any skewness of the guide rod, and once an abnormality is found, it immediately sends a signal to the background control system. After receiving the abnormal signal, the background control system can take corresponding measures according to the preset logic, such as pausing the production line, adjusting the position of the guide rod fixture, or issuing an alarm to notify the operator to intervene, effectively avoiding finished product defects caused by incorrect guide rod position, improving the finished product qualification rate, reducing resource waste, and reducing the cost of production and manufacturing.

[0053] During the entire detection process, the bell jar 6 always clamps the guide rod. After the laser detection device 5 detects that the guide rod is unqualified, the first guide rod clamp 3 releases the guide rod, and the bell jar 6 drives the guide rod into the unqualified product placement area. The double clamping method of the first guide rod clamp 3 and the bell jar 6 is adopted to complete the sorting of unqualified guide rods.

[0054] Furthermore, it also includes a first slide 7, which is located above the bracket 1, and the sliding direction of the first slide 7 is parallel to the conveying direction of the first conveying device 2; the second slide 8 is located above the bracket 1, the first slide 7 and the second slide 8 have an intersection, the sliding direction of the second slide 8 is different from the sliding direction of the first slide 7, and the bell 6 slides along the first slide 7 or the second slide 8; a lane changer is arranged at the intersection of the first slide 7 and the second slide 8, and the lane changer is used to push the bell 6 from the first slide 7 to the second slide 8.

[0055] In this embodiment, the bell 6 clamps the top of the guide rod from beginning to end. At the laser detection device 5, the first guide rod clamp 3 clamps the middle of the guide rod. The double clamping method of the bell 6 and the first guide rod clamp 3 can ensure that the guide rod is located in the middle of the detection space. After the laser detection device 5 completes the detection of the guide rod, it will feed back the detection result to the background control system in the form of a signal. The background control system takes corresponding actions according to the detection result. If the detection result is qualified, the first guide rod clamp 3 and the bell 6 jointly clamp the guide rod and continue to move forward along the first slide 7, and complete the anode assembly above the first lifting platform 4. If the detection result is unqualified, the first guide rod clamp 3 releases the guide rod, and the bell 3 clamping the unqualified guide rod enters the second slide 8 under the action of the lane changer, and enters the unqualified product area through the second slide 8.

[0056] Furthermore, the first guide rod clamp 3 is a pneumatic clamp.

[0057] In this embodiment, the pneumatic grippers can change the gripping force by adjusting the air pressure to adapt to workpieces of different sizes, shapes and weights. This makes them perform well in the face of diverse production tasks and can be easily switched to meet the needs of different application scenarios.

[0058] Further, the laser detection device 5 includes a first base 501, which is arranged on the bracket 1, and the first base 501 is located above the first conveying device 2; there are a plurality of first laser emitters 502, which are arranged in an array at intervals on one side of the first base 501, and the plurality of first laser emitters 502 are distributed in an array along the conveying direction of the first conveying device 2; there are a plurality of first laser receivers 503, which are arranged in an array at intervals on the other side of the first base 501, and the plurality of first laser emitters 502 are distributed in an array along the conveying direction of the first conveying device 2, and the first laser receivers 503 correspond to the first laser emitters 502 one by one; the second lifting platform 50 4, the lifting arrangement is on the bracket 1, and the second lifting platform 504 is close to or away from the first conveying device 2 after lifting; there are a plurality of second laser emitters 505, which are arranged on one side of the second lifting platform 504, and the laser emission direction of the second laser emitter 505 is parallel to the conveying direction of the first conveying device 2; there are a plurality of second laser receivers 506, which are arranged on the other side of the second lifting platform 504, and the second laser emitters 505 correspond to the second laser emitters 505 one by one, and the first laser emitter 502, the first laser receiver 503, the second laser emitter 505, and the second laser receiver 506 form a detection space.

[0059] In this embodiment, the laser beams emitted by the first laser emitter 502 and the second laser emitter 505 are perpendicular to each other, forming a mesh layout. This design can fully scan the guide rod from multiple angles, and both horizontal and vertical bending can be quickly identified. When the steel claw part at the front end of the guide rod is located in the mesh laser gap, any slight bending will cause at least one laser beam to be blocked or refracted, which will be recorded by the corresponding receiver. Once the laser receiver detects an abnormality in laser reception, it means that the guide rod is bent or the size is not up to specification, and the system will immediately feed back this information to the background control system. The background quickly determines whether the guide rod meets the production requirements by analyzing the laser reception situation. If it is unqualified, the corresponding alarm or rejection mechanism is triggered to ensure that only qualified guide rods enter the next assembly process.

[0060] The lifting of the second lifting platform 504 is not only used to adjust the detection space, but also cleverly avoids the transportation path of the guide rod. During the transportation of the guide rod, the second lifting platform 504 descends to avoid the collision of the laser transmitter and receiver with the guide rod, thereby ensuring the safe operation of the equipment. When the guide rod stops above the first lifting platform 4 and is ready for detection, the second lifting platform 504 rises again and cooperates with the detection device on the first lifting platform 4 to form a complete detection space, thereby realizing accurate detection of the guide rod. The mesh detection laser and the second lifting platform 504 improve the flexibility and intelligence level of the device, so that it can adapt to the detection requirements of guide rods of different specifications and types, and improve the versatility and adaptability of the production line.

[0061] Furthermore, the first lifting platform 4 includes a first base 501, which is arranged on one side of the first conveying device 2; the lifting frame 401 is lifted and arranged on the first base 501, and the lifting frame 401 is close to or away from the first guide rod clamp 3 after being lifted and lowered; there are a plurality of rollers 402, all of which are rotatably arranged on the lifting frame 401, and the rollers 402 are distributed in an array along the conveying direction of the first conveying device 2, and the rotation axis of the rollers 402 is perpendicular to the conveying direction of the first conveying device 2 and parallel to the ground, and the rollers 402 are used to receive carbon blocks.

[0062] In this embodiment, the first base 501 is stably mounted on one side of the first conveying device 2, and the lifting frame 401 is disposed on the first base 501. The lifting frame 401 can realize vertical lifting movement under electric, hydraulic or pneumatic drive to meet the operation requirements at different heights, which is conducive to the precise docking of the guide rod and the carbon block.

[0063] Furthermore, it also includes a scissor frame 403, both ends of which are respectively arranged on the first base 501 and the lifting frame 401, and the lifting frame 401 is lifted and lowered on the first base 501 by the scissor frame 403; one end of the first telescopic member 404 is hingedly arranged on the first base 501, and the other end is hingedly arranged on the scissor frame 403. After the first telescopic member 404 is extended and retracted, the scissor frame 403 extends or contracts.

[0064] In this embodiment, the scissor frame 403 is fixed to the first base 501 and the lifting frame 401 at both ends, forming a cross-support structure similar to scissors, which greatly enhances the stability and anti-overturning ability of the lifting frame 401.

[0065] One end of the first telescopic member 404 is hinged on the first base 501, and the other end is hinged on the scissor frame 403. Its telescopic action drives the scissor frame 403 to extend or contract, thereby realizing the up and down movement of the lifting frame 401. Compared with directly driving the lifting frame 401 to move up and down, the flexibility of the mechanical structure is increased, making the lifting process smoother, while also dispersing the load and reducing the pressure on the single driving component.

[0066] Furthermore, it also includes a first rotating driving member, which is located above the bracket 1 and has a driving end; there are a plurality of sprockets, one of which is arranged at the driving end of the first rotating driving device, and the remaining sprockets are rotatably arranged relative to the bracket 1; there are a plurality of catenaries, which are respectively wound around a plurality of sprockets, and a plurality of catenaries form the same path of the first slide 7 and the second slide 8, and the bell 6 slides along the first slide 7 or the second slide 8 through the catenaries.

[0067] In this embodiment, the first rotating driving member is located above the bracket 1, and the driving end of the first rotating driving member drives the catenary to move through the sprocket. The first rotating driving member can transmit power to the bell 6 through the catenary, so that the bell 6 can slide along the first slide 7 or the second slide 8. The power transmission method using the catenary and sprocket can make the layout more diverse, which is convenient for the equipment to adapt to different application sites.

[0068] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
