Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automatic assembly, particularly to a wire harness buckling force feedback mechanism. BACKGROUND

[0002] In the manufacturing process of electronic products, the buckling of the wire harness is a key step, which is related to the overall performance and reliability of the product. However, due to the variety of product wire harnesses, different materials and shapes, and the great influence of the previous process, the use of equipment for automatic buckling of the wire harness faces many challenges.

[0003] In the prior art, the buckling of the wire harness is mostly dependent on manual operation. However, manual buckling has many shortcomings. First, manual operation cannot achieve precise alignment, and the force during buckling cannot be effectively controlled. This results in inconsistent buckling results and low product yield. Second, due to differences in incoming materials, even large size differences, manual operation may not be able to complete the buckling in some cases, further reducing production efficiency. Finally, manual operation can damage the product, increasing production costs and rework rates.

[0004] In order to improve this situation, existing equipment attempts to use air cylinders or servo motors for compression buckling action. However, these devices have obvious deficiencies in force control. Specifically, although air cylinders or servo motors can drive the wire harness to buckle, they cannot finely feedback and adjust the buckling force. This results in problems such as not buckling in place, excessive buckling force causing product damage, and repeated adjustments failing to guarantee the allowable compression force in actual operation. These problems not only affect the quality and reliability of the product, but also increase production costs and maintenance difficulty. SUMMARY

[0005] In view of the above-mentioned shortcomings of the prior art, the purpose of the present utility model is to provide a wire harness buckling force feedback mechanism to solve the problems of low buckling precision and poor force control in the prior art.

[0031] The cable clamping force feedback mechanism provided by the present application, as shown in Figure 1 , comprises a substrate assembly 10, a driving unit 20, a sensing assembly 30 and an adsorption assembly 40.

[0032] Specifically, as shown in Figure 1 and Figure 2 , the substrate assembly 10 comprises a first substrate 11 and a second substrate 12, and the first substrate 11 and the second substrate 12 are movable relative to each other; in the present embodiment, mounting holes 13 and mounting grooves 14 are formed on the first substrate 11 and the second substrate 12, and the mounting holes 13 are provided in plurality, and the mounting holes 13 and the mounting grooves 14 are used for other components.

[0033] The driving unit 20 comprises a first servo cylinder 21 and a second servo cylinder 22, and the output ends of the first servo cylinder 21 and the second servo cylinder 22 are both directed downward, the first servo cylinder 21 is screwed on the first substrate 11 through the mounting hole 13, and the second servo cylinder 22 is screwed on the second substrate 12 through the mounting hole 13;

[0034] The sensing assembly 30 is used to detect the buckling force feedback, and includes a first sensor 31 and a second sensor 32. The fixed ends of the first sensor 31 and the second sensor 32 are respectively arranged at the output ends of the first servo cylinder 21 and the second servo cylinder 22. In this embodiment, the first sensor 31 and the second sensor 32 are both elastic sensors. When the first sensor 31 and the second sensor 32 are subjected to pressure during buckling, the measured pressure is converted into an electrical signal, thereby reflecting the size of the measured buckling force.

[0035] As shown in Figure 1 and Figure 3 , the adsorption assembly 40 includes a rigid suction head 41 and a flexible suction head 42, which are respectively arranged at the force receiving ends of the first pressure sensor and the second sensor 32. The rigid suction head 41 includes a connecting portion 411 and a rigid adsorption portion 412, which are integrally formed. The flexible suction head 42 includes a connecting portion 411 and a flexible adsorption portion 421, which is made of foam material.

[0036] It should be noted that, as shown in Figure 4 , the wire 50 applied in this mechanism has two different adsorption ends, namely a flexible end 51 and a rigid end 52. The flexible end 51 is pasted with foam, and the rigid end 52 is installed with a metal sheet. Before completing the buckling action, the adsorption and pickup of the wire 50 need to be completed. The rigid suction head 41 is used to adsorb the flexible end 51, and the flexible suction head 42 is used to adsorb the rigid end 52. Through the rigid and flexible combined adsorption mode, it can be ensured that the two can be adsorbed tightly when vacuum adsorption, and the buckling process can be ensured to prevent the wire 50 from falling off.

[0037] Preferably, as shown in Figure 1 , in order to further improve the precision and stability of buckling, the embodiment further provides a connecting piece 73 between the output end of the first servo cylinder 21 and the fixed end of the first pressure sensor, and between the output end of the second servo cylinder 22 and the fixed end of the second pressure sensor. The design of the connecting piece 73 can ensure that the output force of the servo cylinder can be stably transmitted to the pressure sensor and the adsorption device, while reducing the error caused by vibration or impact.

[0038] As shown in Figure 1 and Figure 5 , in order to further enhance the versatility and adaptability of the equipment, the embodiment further includes an adjusting unit. The adjusting unit includes an X-axis displacement assembly 60 and a Y-axis displacement assembly 70. The X-axis displacement assembly 60 and / or the Y-axis displacement assembly 70 are arranged on the first base plate 11 and / or the second base plate 12.

[0039] The X-axis displacement assembly 60 and the Y-axis displacement assembly 70 each include a motor 61, a guide rod 62, a screw rod 63, and a fixed seat 64. The output end of the motor 61 is coaxially connected with the screw rod 63, the screw rod 63 is threadedly connected with the fixed seat 64, the fixed seat 64 is slidingly connected with the guide rod 62, and the fixed seat 64 is moved by rotating the screw rod 63 by the motor 61; and the fixed seat 64 is arranged on the first base plate 11 and / or the second base plate 12.

[0040] Specifically, the fixed seats 64 of the X-axis displacement assembly 60 and the Y-axis displacement assembly 70 can be mounted together on the first base plate 11 or the second base plate 12, or can be mounted on the first base plate 11 and the second base plate 12 respectively. Therefore, the mechanism can control the relative position of the rigid suction head 41 and the flexible suction head 42 by moving the position of the first base plate 11 or the second base plate 12 alone, or can control the relative position of the rigid suction head 41 and the flexible suction head 42 by moving the position of the first base plate 11 and the second base plate 12 respectively.

[0041] In a preferred embodiment, the X-axis displacement assembly 60 and the Y-axis displacement assembly 70 are mounted on the second base plate 12, and the fixed seat 64 is mounted on the second base plate 12. The second base plate 12 is moved left and right by the X-axis displacement assembly 60, and the second base plate 12 is moved forward and backward by the Y-axis displacement assembly 70, so as to adjust the relative position of the rigid suction head 41 and the flexible suction head 42. The X-axis displacement assembly 60 and the Y-axis displacement assembly 70 can adjust the distance between the rigid suction head 41 and the flexible suction head 42, so as to adapt to the flat cable 50 with different positions of the flexible end 51 and the rigid end 52.

[0042] Further, in order to improve the installation flexibility of the suction head, a suction head fixing member 71 is arranged between the first pressure sensor and the rigid suction head 41, and between the second pressure sensor and the flexible suction head 42. The first base plate 11 and the second base plate 12 are slidingly connected with the suction head fixing member 71, and the rigid suction head 41 and the flexible suction head 42 are threadedly connected with the suction head fixing member 71.

[0043] Further, the first base plate 11 and the second base plate 12 are each provided with a wire rail 72, the wire rail 72 is mounted on the mounting groove 14, and the suction head fixing member 71 is slidingly connected with the first base plate 11 and the second base plate 12 through the wire rail 72, so as to ensure that the rigid suction head 41 and the flexible suction head 42 can move linearly.

[0044] In order to further improve the adsorption effect, a plurality of adsorption holes are arranged on the rigid suction head 41 and the flexible suction head 42. The design of the adsorption holes can increase the adsorption area and improve the adsorption force, so as to ensure that the flat cable 50 can be stably maintained on the adsorption device during the buckling process.

[0045] In summary, in the buckling process, the control system closely tracks the preset buckling force range and its allowable error threshold, continuously receives and analyzes real-time feedback signals from the first pressure sensor and the second pressure sensor. Once it is detected that the buckling force exceeds the preset safety range, or the error value breaks the allowed limit, the control system will quickly intervene and dynamically adjust the working parameters of the first servo cylinder and the second servo cylinder. This process ensures that the buckling force can be stably maintained within the preset precision range, while the error is strictly controlled within the allowed range.

[0046] The servo cylinder, as the driving core, can independently control the rigid suction head and the flexible suction head to move up and down accurately to complete the buckling action of the product. When reaching the predetermined buckling position, the product will generate a reverse force, which will be effectively captured by the mechanism. The servo cylinder can sensitively perceive the size of this force through the changes of current, voltage and speed parameters by virtue of its built-in sensing mechanism, and accordingly execute closed-loop control strategy to realize real-time force value adjustment.

[0047] At the same time, the pressure sensor also continuously monitors and reports the reverse force of the product, providing another accurate detection means for the control system. The force feedback mechanism of the servo cylinder and the precise detection of the pressure sensor combine to build an efficient and accurate buckling pressure monitoring system. This system not only can realize real-time and accurate measurement of the buckling pressure, but also can quickly adjust the control strategy according to the measurement results to ensure that each buckling action can meet the expected precision requirements, realizing fine management and control of the product buckling process.

[0048] The above embodiments only exemplarily illustrate the principles and effects of the present application, and are not used to limit the present application. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present application. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought disclosed by the present application should be covered by the claims of the present application.
