As important connecting components in electrical equipment, the accuracy of the installation of positive and negative wire harnesses directly affects the performance and safety of the equipment. Before assembly, the positive and negative wire harnesses must be oriented correctly to ensure smooth subsequent connection and normal circuit conduction.

[0003] Traditional production lines still rely on manual turning, which is low in efficiency. Workers need to spend a lot of time on turning and positioning a single wire harness in repeated turning work, which is difficult to meet the needs of large-scale production and seriously hinders the improvement of production efficiency. Secondly, the quality stability of manual operation is poor. There are differences in operation methods and proficiency among different workers, and even the same worker is prone to fatigue after a long time of work. These factors make it difficult to ensure the consistency of wire harness turning, thereby increasing the product failure rate.

[0004] Existing turnover devices are few for positive and negative wire harness production, and most of them have complex structures and are cumbersome to operate, making it difficult to meet the requirements of efficient production. SUMMARY

DETAILED DESCRIPTION

[0024] The application will be further described in detail below with reference to the accompanying drawings.

[0025] As shown in Figs. 1-3 , a turnover mechanism for turning over positive and negative wire harnesses, the turnover mechanism comprising a receiving plate 1, a blocking device 2, a rotating shaft 3, and a lifting device 4, one end of the lifting device 4 being connected with the receiving plate 1, the other end of the lifting device 4 being connected with the blocking device 2, the lifting device 4 driving the blocking device 2 to block one end of the receiving plate 1, the rotating shaft 3 being connected with the receiving plate 1, the rotating shaft 3 rotating to drive the receiving plate 1 to rotate.

[0026] The device has two modes of use. When the wire harness is placed on the receiving plate 1 with the front side up, the receiving plate 1 is fixed, the lifting device 4 drives the blocking device 2 to move, so that one end of the receiving plate 1 is open, and since the receiving surface 11 of the receiving plate 1 is inclined, the wire harness directly slides down, i.e. is not turned over. When the wire harness is placed on the receiving plate 1 with the back side up, the rotating shaft 3 rotates to drive the receiving plate 1 to rotate, at this time the receiving plate 1 is connected with the blocking device 2 through the lifting device 4, the positional relationship between the receiving plate 1 and the blocking device 2 is relatively fixed, therefore the blocking device 2 blocks one end of the receiving plate 1, and the receiving plate 1 and the blocking device 2 rotate together with the rotating shaft 3, when rotated to a certain angle, the wire harness on the receiving plate 1 is turned over from the receiving plate 1 and falls, becoming placed with the front side up.

[0027] Preferably, the receiving plate 1 is made of lightweight and high-strength carbon fiber composite material or high-strength aluminum alloy material, the overall weight is not large, and the carrying capacity can be ensured. The inclination angle of the receiving surface 11 of the receiving plate 1 is accurately designed to be 15°-45°, so as to adapt to the sliding needs of the positive and negative wire harnesses. The surface is treated with a special anti-skid coating to prevent the wire harness from sliding randomly when placed. The end of the receiving plate 1 close to the blocking device 2 is open, and is blocked by the blocking device 2.

[0028] Preferably, the turnover mechanism further comprises a visual recognition device and a control system. The turnover mechanism selects a high-precision industrial camera matched with intelligent image analysis software, which is installed above the receiving plate 1 to ensure that the placement state of the wire harness on the receiving plate 1 can be clearly captured. The camera is fixed by a metal frame to ensure that the shooting angle is stable and not affected by the movement of the turnover mechanism. The visual recognition device is connected to the control system, and the collected image data are transmitted to the control system in real time for analysis and processing. The data transmitted by the visual recognition device are integrated, the placement state of the wire harness is analyzed, it is judged whether the wire harness is placed face up or face down, and then corresponding instructions are sent to the lifting device 4, the blocking device 2 and the shaft 3 driving motor 5 to realize automatic control of the whole turnover or transfer process.

[0029] The coordinated operation of the visual recognition device and the components of the turnover mechanism realizes fully automatic operation without excessive manual intervention. Whether it is wire harness turnover or transfer, it can be quickly and accurately completed, greatly improving production efficiency and meeting large-scale and high-intensity production needs.

[0030] The visual recognition device can accurately identify the placement state of the wire harness, avoiding human judgment errors. Combined with stable mechanical structure and precise control, the problem of inconsistent wire harness turnover is further reduced, and the product failure rate is significantly reduced, effectively ensuring product quality.

[0031] Preferably, the lifting device 4 is perpendicular to the receiving surface 11 of the receiving plate 1. The lifting device 4 adopts a cylinder, a hydraulic cylinder or a screw rod elevator. For example, the lifting device 4 adopts a screw rod elevator driven by a motor 5 to rotate the screw rod, thereby driving the nut to move up and down linearly, realizing the lifting of the blocking device 2 connected with the nut. The screw rod elevator has reliable self-locking function, which can ensure that the blocking device 2 stays stably after rising or descending to the specified position. In particular, the lifting device 4 is connected with the receiving plate 1 through a customized right-angle connecting seat, ensuring that the lifting device 4 is perpendicular to the receiving surface 11 of the receiving plate 1. This perpendicular connection ensures that the blocking device 2 can always maintain a precise relative position relationship with the receiving plate 1 during lifting, and is not affected by other directional forces. The connecting seat and the receiving plate 1 are connected by adjustable bolts, which facilitates fine adjustment of the relative position of the receiving plate 1 and the blocking device 2 according to different wire harness specifications.

[0032] The lifting device 4 is perpendicular to the receiving surface 11 of the receiving plate 1, so that the blocking device 2 is more evenly stressed and runs more stably during lifting. This effectively avoids the shaking or deviation of the blocking device 2 caused by the inclination of the lifting device 4, ensures the reliability when blocking one end of the receiving plate 1, and the smoothness and stability of the wire harness sliding when the receiving plate 1 is opened, and reduces production failures caused by unstable mechanical structure.

[0033] The vertical arrangement makes the relative position between the receiving plate 1 and the blocking device 2 more fixed and accurate. During the turnover process, the position and movement trajectory of the wire harness can be more accurately controlled, further improving the accuracy of the turnover operation. Combined with the visual recognition device and the precise control system, the turnover error of the wire harness can be controlled within a very small range, greatly reducing the defective rate caused by inaccurate turnover and improving the product quality.

[0034] The lifting device 4 is uniformly stressed, reducing the wear and fatigue of each component and prolonging the overall service life of the equipment. At the same time, this simple and clear vertical structure design makes the maintenance and repair of the equipment more convenient, reduces the maintenance cost and downtime, and improves the production efficiency.

[0035] Preferably, as shown in Fig. 1 and Fig. 3 , the blocking device 2 is bent to form a connecting section 21 and a blocking section 22, the connecting section 21 is connected to the blocking section 22, the connecting section 21 is arranged below the receiving plate 1, and the blocking section 22 is arranged at one end of the receiving plate 1, and the lifting device 4 is connected to the connecting section 21 and the receiving plate 1.

[0036] Preferably, the blocking device 2 is integrally bent from high-strength aluminum alloy material to ensure structural strength and stability. The connecting section 21 and the blocking section 22 formed by bending are at a 90° angle, the connecting section 21 is below the receiving plate 1, and its length is customized according to actual needs to ensure stable connection with the lifting device 4. A plurality of evenly distributed mounting holes are provided on the connecting section 21, which are tightly connected to the output end of the lifting device 4 through bolts. The blocking section 22 is located at one end of the receiving plate 1, and the surface is ground to increase the friction with the wire harness and prevent accidental sliding of the wire harness during turnover or sliding. More preferably, on the side of the blocking section 22 close to the receiving plate 1, a protrusion is designed to match the clamping groove of the receiving plate 1, and when the blocking device 2 rises to the blocking position, the protrusion can accurately fit into the clamping groove to achieve tight fit.

[0037] The bending design of the blocking device 2 makes the connecting section 21 below the receiving plate 1, effectively utilizing the space inside the equipment, avoiding the bulkiness of the structure, making the entire turnover mechanism more compact, and suitable for production workshops with limited space.

[0038] The height and surface treatment design of the blocking section 22 increase the friction with the wire harness, better play the blocking role, prevent accidental sliding or rolling of the wire harness on the receiving plate 1, and ensure that the wire harness can be stably placed on the receiving plate 1 during turnover or non-turnover operation, improving the safety and reliability of the operation.

[0039] Further, the connecting section 21 comprises a first connecting section 211, a second connecting section 212 and a third connecting section 213 connected in sequence, the third connecting section 213 is closer to the receiving plate 1 than the first connecting section 211, the second connecting section 212 and the first connecting section 211 have an included angle, the third connecting section 213 is connected with the blocking section 22, and the lifting device 4 is connected with the first connecting section 211 and the receiving plate 1.

[0040] The connecting section 21 is made of high-strength aluminum alloy material to ensure its stability when bearing the force of the lifting device 4 and the working of the blocking device 2. The length of the first connecting section 211 is customized according to the distance between the lifting device 4 and the receiving plate 1, one end of which is adapted to the output end of the lifting device 4, and a plurality of mounting holes are uniformly distributed on the first connecting section 211 and are tightly connected with the lifting device 4 through high-strength bolts. The cross-sectional shape of the first connecting section 211 is rectangular to enhance its bending resistance.

[0041] Preferably, the second connecting section 212 is perpendicular to the first connecting section 211, and a reinforcing rib is arranged between the first connecting section 211 and the second connecting section 212.

[0042] Further, the third connecting section 213 is closer to the receiving plate 1, one end of which is firmly connected with the blocking section 22, and the connection is reinforced, such as using thickened plate or adding reinforcing ribs, to ensure the strength when the blocking device 2 works.

[0043] The three-section design of the connecting section 21, especially the included angle between the second connecting section 212 and the first connecting section 211, enables the adjustment of the angle to adapt to different production layouts and equipment requirements during installation and debugging. Compared with a single connecting section 21, more adjustment flexibility is added, which facilitates fine adjustment of the relative position of the blocking device 2 and the receiving plate 1 according to the actual production situation.

[0044] The structure of the three-section connecting section 21 leaves space for the arrangement of the lifting device 4 and can to some extent play a buffering role. When the lifting device 4 works, the force is transmitted to the second connecting section 212 through the first connecting section 211, and the force is gradually decomposed and buffered, reducing the impact of the instantaneous impact force on the blocking device 2 and the receiving plate 1, thereby prolonging the service life of the equipment and reducing the occurrence rate of equipment failure.

[0045] In a preferred embodiment, the first connecting section 211 and the third connecting section 213 are both parallel to the receiving surface 11. The parallelism of the first connecting section 211 and the third connecting section 213 to the receiving surface 11 enables the force of the lifting device 4 on the blocking device 2 to be evenly distributed on the receiving surface 11, avoiding excessive local stress caused by the inclination of the connecting section 21. This helps to improve the mechanical stability of the entire turnover mechanism, reduces the shaking and vibration caused by uneven stress during turnover, and ensures the smoothness of the positive and negative wire harness turnover operation.

[0046] In another preferred embodiment, as shown in Fig. 3 The third connecting section 213 is bent to form a recess 2131 that avoids the rotation shaft 3. During the processing of the third connecting section 213, a numerical control bending machine is used for precise bending operation. According to the position and size of the rotation shaft 3, precise bending parameters are input into the numerical control system to ensure that the formed recess 2131 can properly avoid the rotation shaft 3. The bending die is made of high-strength and high-precision special die to ensure the size accuracy and surface quality of the bending part. During installation, the third connecting section 213 is preliminarily positioned with the second connecting section 212 through a positioning pin, and then the entire blocking device 2 assembly is placed close to the receiving plate 1 and the rotation shaft 3. Through the guide block previously set in the recess 2131, the recess 2131 can smoothly pass through the rotation shaft 3, ensuring the uniform gap between the third connecting section 213 and the rotation shaft 3, and avoiding collision or friction during equipment operation. At the same time, the position of the third connecting section 213 is fine-tuned using adjusting bolts to ensure the connection accuracy with other components. After bending, the size and position of the recess 2131 are accurately measured using a three-coordinate measuring instrument, and compared with the design value to ensure that the deviation is within the allowable range. After installation is completed, perform empty load and load trial operation to check the avoidance between the third connecting section 213 and the rotation shaft 3, and the stability of the entire blocking device 2 during operation.

[0047] The recess 2131 of the third connecting segment 213 is designed to effectively avoid spatial interference with the rotating shaft 3, making the structure of the whole turnover mechanism more compact, and enabling reasonable arrangement of various components in limited space, thereby improving the integration of the equipment and adapting to the space requirements of different production sites. Since the recess 2131 precisely avoids the rotating shaft 3, vibration and noise generated by collision or friction between components are reduced, making the whole turnover mechanism more stable during operation. This not only improves the stability of the equipment, but also reduces the probability of equipment failure, thereby ensuring the continuity of production. The clear avoidance structure enables more convenient operation of the rotating shaft 3 and the third connecting segment 213 during equipment maintenance and repair. For example, when replacing the rotating shaft 3 or inspecting the third connecting segment 213, it is not necessary to disassemble too many components, thereby saving maintenance time and cost. Hard contact and friction between components are avoided, wear is reduced, especially the wear of the rotating shaft 3 and the third connecting segment 213, thereby prolonging the service life of the whole turnover mechanism and reducing the replacement frequency of the equipment, thereby saving costs for enterprises.

[0048] Further, the second connecting segment 212 and the first connecting segment 211 are perpendicular, and the blocking segment 22 and the third connecting segment 213 are perpendicular.

[0049] Referring to Fig. 1 The turnover mechanism further comprises a motor 5, the rotating shaft 3 is connected with the motor 5, the motor 5 drives the rotating shaft 3 to rotate, and the motor 5 is selected according to the load requirement, the speed requirement and the working environment of the turnover mechanism, and a motor 5 of a suitable type and power is selected. For example, for a scene with a large load and a requirement for accurate speed control, a servo motor 5 can be selected; if the load is relatively small and the speed accuracy requirement is not high, an alternating current asynchronous motor 5 can be selected.

[0050] A coupling or a transmission belt is used to connect the output shaft of the motor 5 with the rotating shaft 3. If a coupling is selected, a high-precision and high-rigidity elastic coupling is selected, which can not only compensate for the possible slight coaxiality deviation between the output shaft of the motor 5 and the rotating shaft 3, but also play a buffering and damping role, thereby reducing the damage to the motor 5 and the rotating shaft 3 caused by the impact when starting and stopping. When installing the coupling, strict operation procedures are followed to ensure the firmness and concentricity of the connection.

[0051] Further, the turnover mechanism further comprises a bracket 6, the motor 5 and the rotating shaft 3 are installed on the bracket 6.

[0052] The embodiments of the specific implementation mode are preferred embodiments of the utility model, and do not limit the protection scope of the utility model, so that: equivalent changes made according to the structure, shape and principle of the utility model should be covered within the protection scope of the utility model.
