Description

Technical Field

[0001] The utility model particularly relates to a tinning device for the end of a wire harness. Background Art

[0002] Tinning at the end of a wire harness means that the tail piece structure of the pin of the terminal is bent and wrapped around the wire harness to make the connection firm, and the stability of the terminal pin is further enhanced by tinning. For example, a tinning device for the end of a wire harness disclosed in the authorized publication number CN220964020U has the following working principle: after the terminal is placed in the end crimping frame, the upper moving die is driven to descend by the push rod piston rod, the mounting plate will move downward close to the end crimping frame. When the pressure head on the lower surface of the mounting plate initially contacts the tail piece structure of the terminal, the pressure head applies pressure to the tail piece structure of the terminal, and both sides of the tail piece structure of the terminal move closer to the middle and enter the extrusion groove. When the pressure end plate and the end crimping frame approach, the tail piece structure of the terminal will deform to form a circular structure on the inner walls of the extrusion groove and the terminal insertion groove, and wrap around the wire harness. When the end crimping frame moves to the rear position in the positioning and guiding frame, the tinning head tins the terminal, and the end crimping frame resets to complete the tinning operation at the end of the wire harness.

[0003] However, the above device has the following problems during use: since multiple wire harnesses are subjected to end crimping operations, before end crimping, the wire harnesses need to be neatly arranged on the end crimping frame and correspond to the tinning heads one by one; if the wire harnesses are entangled or deviate from their original positions when the end crimping frame moves on the positioning and guiding frame, the operator needs to re-arrange them; or if the operator accidentally hits the wire harnesses, the wire harnesses will also shift, thus increasing the operator's re-arrangement process.

A positioning and guiding frame 2 is arranged between the termination mechanism and the tinning mechanism. The positioning and guiding frame 2 is slidably arranged with the operating table 1. Mounting seats 3 are respectively arranged on both sides of the positioning and guiding frame 2. A pressure roller 4 is arranged between the two mounting seats 3. Adjusting members are respectively arranged at both ends of the pressure roller 4. An activity groove 5 is formed on each mounting seat 3. The adjusting members are slidably arranged in the activity groove 5. The pressure roller 4 compresses and positions the wire harness 6 under the action of the adjusting members.

[0023] Furthermore, the adjusting member includes a slider 71 slidably arranged in the activity groove 5. A spring 72 is arranged between the slider 71 and the top wall of the activity groove 5. The slider 71 is connected to the pressure roller 4.

[0024] Furthermore, the pressure roller 4 is a rubber roller.

[0025] Further, the terminal crimping mechanism includes a mounting bracket 81 provided on the operating table 1. A first driving device 82 is provided on the mounting bracket 81. One end of the first driving device 82 passes through the mounting bracket 81 and is connected to a crimping die 83. The crimping die 83 is located above the positioning and guiding frame 2. A plurality of limiting grooves 21 are provided on the positioning and guiding frame 2, and grooves 831 adapted to the limiting grooves 21 are provided on the crimping die 83.

[0026] Further, the soldering mechanism includes a vertical bracket 91 provided on the operating table 1. A second driving device 92 is provided on the vertical bracket 91. One end of the second driving device 92 passes through the vertical bracket 91 and is connected to a connecting plate 93. A plurality of soldering heads 94 are provided at the lower end of the connecting plate 93.

[0027] Further, a sliding groove 10 is formed on the operating table 1, and a convex block 11 slidably engaged with the sliding groove 10 is provided on the positioning and guiding frame 2.

[0028] The working principle of the present utility model is as follows:

[0029] As Figure 2 shown, the wire harness 6 is arranged neatly on the positioning and guiding frame 2. The specific usage method is as follows: First, lift the pressure roller 4 upward. Since the two ends of the pressure roller 4 are respectively connected to the sliders 71, and a spring 72 is connected between the sliders 71 and the top wall of the movable groove 5, when the pressure roller 4 moves upward, it will drive the sliders 71 to move upward, thereby squeezing the spring 72 and deforming the spring 72. Then, arrange the wire harness 6 under the pressure roller 4, place the end of the wire harness 6 that needs terminal crimping operation in the limiting groove 21. After arranging it neatly, release the pressure roller 4. At this time, the pressure roller 4 drives the sliders 71 to move downward under the action of gravity, thereby stretching the spring 72. When the pressure roller 4 presses on the wire harness 6, the pressure roller 4 stops moving. Then, start the first driving device 82. Since one end of the first driving device 82 passes through the mounting bracket 81 and is connected to the crimping die 83, and grooves 831 adapted to the limiting grooves 21 are provided on the crimping die 83, when the first driving device 82 drives the crimping die 83 to move downward, the grooves 831 on the crimping die 83 and the limiting grooves 21 on the positioning and guiding frame 2 jointly perform the terminal crimping operation on the end of the wire harness 6 (the detailed working principle of the terminal crimping operation has been published in detail in the patent with the authorization announcement number CN220964020U and belongs to common general knowledge, so it will not be elaborated herein). After the terminal crimping operation is completed, move the positioning and guiding frame 2. The positioning and guiding frame 2 will drive structures such as the pressure roller 4, the mounting seat 3, and the adjusting member to move synchronously. When the positioning and guiding frame 2 moves to the lower part of the vertical bracket 91, make the end of the wire harness 6 that needs soldering be directly below the soldering heads 94. Then, start the second driving device 92. The second driving device 92 drives the connecting plate 93 to move downward, so that the soldering heads 94 on the connecting plate 93 move downward to perform the soldering operation on the wire harness 6.

[0030] In the above technology, the pressure roller 4 is preferably a rubber roller, which can reduce the damage of the pressure roller 4 to the wire harness 6. In the technology of the present application, a chute 10 can be opened on the operating table 1, and a convex block 11 cooperating with the chute 10 is arranged on the positioning and guiding frame 2. When the positioning and guiding frame 2 moves relative to the operating table 1, the convex block 11 moves in the chute 10. The structural cooperation between the convex block 11 and the chute 10 can guide the movement track of the positioning and guiding frame 2, so that the positioning and guiding frame 2 can accurately move below the tin - point mechanism. A telescopic cylinder can be connected to the positioning and guiding frame 2 to drive the positioning and guiding frame 2 to move back and forth, or the telescopic amount of the telescopic cylinder can be controlled to make the telescopic cylinder control the moving amount of the positioning and guiding frame 2 on the operating table 1. Both the first driving device 82 and the second driving device 92 mentioned above can be selected as telescopic cylinders to achieve.

[0031] In order to solve the problem that the wire harness may be displaced under external force in the present application, structures such as a mounting seat and a pressure roller are arranged on the positioning and guiding frame, which have the functions of combing and positioning the wire harness, preventing the wire harness from being displaced and thus affecting the terminal - making and tin - point operations.

[0032] Although the present invention has been described in detail with reference to the above embodiments, it is obvious to those skilled in the art through the present disclosure that various changes or modifications can be made to the present invention without departing from the principle and spirit scope defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, rather than to limit the present invention, and the scope of protection is defined by the content of the claims.
