Description

Technical Field

[0001] The present invention relates to the technical field of production equipment, and in particular to production equipment for electric vehicle connecting line terminals. Background Art

[0002] In the production process of electric vehicle plastic parts, in order to improve efficiency and ensure product quality, automated equipment is used to handle the loading of connecting wires. They are responsible for accurately placing the connecting wires with terminals into the injection mold and removing the finished product after the injection molding process is completed.

[0003] According to the publication number: CN116653206B, the patent name is: Electric vehicle plastic parts production equipment, which includes a loading unit for loading the connecting wires with terminals into the injection mold and a removing unit for removing the connecting wires with completed terminal injection from the injection mold, and solves the problem that the round hole terminals cannot fall and engage with the lower mold base during the movement process, and also provides a base at the end of the connecting wire to push all the connecting wires to be neatly arranged.

[0004] Although this automated method theoretically improves production efficiency, it has limitations in practical application. The current operation mode is only applicable to those connecting wires whose end rubber rings have been cut. This means that manual intervention is required to cut the rubber at the end of the connecting wire before the automation process. This additional manual step not only increases production costs, but may also lead to inconsistent cutting quality, which in turn affects the quality of the product. To this end, we propose an electric vehicle connecting wire terminal production equipment. Summary of the invention

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Refer to the attached Figure 1-12 The embodiment of the present invention provides an electric vehicle connecting wire terminal production device, including a workbench 1, on which an injection mold 2 for injecting a connecting wire is arranged, and a lower mold 11 is also arranged on the workbench 1, and a sink 12 is opened on one side of the lower mold 11 on the workbench 1, and a baffle 14 is suspended on the sink 12, and the bottom of the sink 12 and the bottom of the baffle 14 are connected by a plurality of arrays of first springs 13 to form a support for a support assembly 3 installed thereon, and the support assembly 3 is installed on the workbench 1 and is located on the upper part of the baffle 14, and the support assembly 3 includes a support platform 31, a support guide rod 32, and a support The support slide 33 is installed on the edges of both sides of the workbench 1 to guide the support platform 31 to move in its stroke. Support guide rods 32 are provided on both sides of the support platform 31. The support guide rods 32 slide in cooperation with the support slide 33. The support slide 33 is a two-stage and bent slide. The two sections of the slide are distributed up and down and connected. The angle between the two sections of the slide is an acute angle, so that the support platform 31 moves forward and then moves forward. The inclination angle of the upper section and the horizontal plane is controlled at 6-15 degrees. When the support platform 31 slides along the stroke of the support slide 33, the inclination angle is adjusted according to the required sensitivity;

[0037] As the injection mold 2 is driven downward, the support platform 31 will be displaced along the travel of the support slide groove 33, and the support platform 31 will squeeze the baffle 14 and slide left and right. Since the baffle 14 and the support platform 31 are in surface-to-surface contact, a large friction force will be generated. In order to overcome this friction force, a slider is provided on the baffle 14, and a slide rail is provided at the bottom of the support platform 31, and the friction is reduced by using the slide rail and the slider in combination;

[0038] A contact guide rod 37 is installed on the injection mold 2, which can drive the support platform 31 to move along the support slide groove 33. In order to solve the clamping of the connecting line, placement grooves are equidistantly provided on the surface of the support platform 31, and through holes 34 are provided between the placement grooves. A mounting rod 35 is provided on the inner wall of the through hole 34 along the direction of the placement groove, and the through hole 34 is long and has a length sufficient for the support platform 31 to move forward and backward. The mounting rod 35 is sleeved with a pressure plate 36 and reset by a torsion spring, and a contact head 38 is installed on the end of the contact guide rod 37. When the contact head 38 contacts the pressure plate 36, the pressure plate 36 is connected with the mounting rod 35. The center is deflected in the direction of the placement groove, and the connecting line is compacted. Since the stroke of the support slide groove 33 is to drive the support platform 31 to move forward and then forward, the through hole 34 needs to be in the shape of a long strip to give the support platform 31 enough stroke when sliding. In order to enable the pressure plate 36 to deflect in the direction of the placement groove, the contact head 38 and the contact end of the pressure plate 36 are inverted trapezoidal structures. In order to facilitate the sliding between the contact surface of the contact head 38 and the pressure plate 36, a section is made on the outer arc part of the pressure plate 36 to make it match the section of the contact head 38, so that the pressure plate 36 is turned over and clamps the connecting line in the placement groove, and at the same time, the stroke of the support platform 31 is not affected;

[0039] A contact pressure roller 39 is also installed on the contact guide rod 37, and the contact pressure roller 39 extends to the rear of the support platform 31. When the contact guide rod 37 moves downward, the contact head 38 controls the pressure plate 36 to clamp the connecting line and drive the support platform 31 to move backward. When the contact guide rod 37 continues to move downward until the middle of the lower stroke of the support slide groove 33, it is supported by the sink groove 12. The contact guide rod 37 continues to move downward, and the support platform 31 continues to move forward. The contact pressure roller 39 is abutted against the support platform 31, and the support platform 31 squeezes the baffle 14 to provide a supporting part for pressing the support platform 31 until the stroke ends. At this time, one end of the support platform 31 remains parallel to one end of the terminal groove 111 on the lower mold 11, and the injection mold 2 performs an injection molding process on its connecting part. After the injection molding is completed, in order to eject it from the lower mold 11, the cylinder installed at the bottom of the workbench 1 pushes out the terminal in the terminal groove 111 (not shown in the figure).

[0040] In order to realize the stripping of the end of the connecting wire, an intermediate component 4 is arranged between the lower mold 11 and the supporting component 3. The intermediate component 4 includes a supporting unit 5 and a stripping unit 6. The supporting unit 5 is used to support the lifting and lowering of the stripping unit 6.

[0041] The stripping unit 6 includes a main body 61, an upper plate 62, a lower plate 63, a rack 66, and a limiting rod 67. The main body 61 has a pair of flanges extending outwardly to the same side. The upper plate 62 and the lower plate 63 are rotatably arranged on the flanges through an upper shaft 621 and a lower shaft 631. The upper plate 62 and the lower plate 63 are rotatably arranged on the main body 61 to clamp the connecting wire placed on the supporting platform 31. The upper plate 62 and the lower plate 63 are also provided with a stripping hole 68 for the connecting wire to pass through. A cutting knife is arranged in the stripping hole 68. The stripping hole 68 corresponds to the placement groove on the supporting platform 31. The connecting wire is placed in the placement groove and extends into the stripping hole 68 until it abuts against the main body 61. This can ensure that when the stripping unit 6 strips the connecting wire, the length of the exposed wire core is consistent, thereby improving the installation consistency.

[0042] In order to achieve the peeling effect of the upper plate 62 and the lower plate 63, a driving shaft 64 and a driven shaft 65 are installed on the main body 61 and extend to both sides of the main body 61. The driving gear 641 and the driven gear 651 are respectively rotatably sleeved on both sides of the driving shaft 64 and the driven shaft 65. The driving gear 641, the driven gear 651, the lower gear 632, and the upper gear 622 are meshed, so that the upper plate 62 and the lower plate 63 can be driven to clamp each other by rotating the driving gear 641. The equipment has a reasonable design, a compact structure, saves space, and is easy to be integrated into the production line.

[0043] In order to drive the rotation of the active tooth 641, a rack 66 connected to the injection mold 2 is used to mesh with the active tooth 641 to drive it to rotate, and a limit rod 67 is connected to the rack 66 to limit the active tooth 641. The limit rod 67 can use an arc-shaped rack to limit the rotation of the active tooth 641, which is convenient for the subsequent downward pressure on the stripping unit 6 to avoid blocking the support platform 31 and the lower mold 11 from approaching each other. When it moves, when the injection mold 2 is pressed down, the rack 66 preferentially drives the active tooth 641 to rotate, driving the upper plate 62 and the lower plate 63 to press and cut the connecting line. When the limit rod 67 is in contact with the active tooth 641, the pressure plate 36 clamps the connecting line, the injection mold 2 continues to be pressed down, and the limit rod 67 drives the overall descent of the stripping unit 6.

[0044] In order to facilitate the control of the stroke and support of the stripping unit 6, support units 5 are installed on both sides of the workbench 1. The support unit 5 includes a guide plate 51 with a groove in the middle, a second spring 52 is arranged in the groove of the guide plate 51, and a drag plate 53 is installed on the second spring 52. The drag plate 53 is provided with an arc surface for supporting the active shaft 64. The lower part of the active shaft 64 can also be connected to a limiting shaft extending into the groove and there is a gap with the edge of the spring. When the rack 66 drives the active tooth 641, since the second spring 52 can provide a certain supporting force until it abuts against the limiting rod 67, the second spring 52 is not enough to support the downward pressure deformation of the limiting rod 67 on the active tooth 641, so that the stripping unit 6 is caused to drop into the sink 12 as a whole to make room between the connecting line and the terminal.

[0045] When in use, the connecting wire is placed in the placement groove of the support platform 31 and pressed forward against the side wall of the main body 61. The injection mold 2 is pressed downward to drive the rack 66 to drive the active tooth 641 to rotate. The rotation of the active tooth 641 controls the relative movement of the upper plate 62 and the lower plate 63 until the limit rod 67 and the active tooth 641 are pressed against each other to limit it. At this time, the blade in the stripping hole 68 bites the insulating layer sleeve at the end of the connecting wire. At the same time, the contact head 38 on the contact guide rod 37 clamps the connecting wire and the support slide groove 33 controls the overall tilting of the support platform 31 backward and then forward to achieve the stripping of the end of the connecting wire. It should be noted that according to the material of the wire core, the wire core will warp during stripping. During debugging, it is necessary to appropriately adjust the slope of the terminal groove 111 in the lower mold 11 according to the curvature of the warping so that it is adapted to the curvature of the warping. When the support platform 31 moves to the support slide groove At the middle section of the lower section 33, the contact roller 39 on the contact guide rod 37 is in contact with the support platform 31. It should be noted that since the contact roller 39 will give downward pressure and friction to the support platform 31, it is necessary to select a roller with high strength and low friction. A groove for the roller to slide can be provided on the support platform 31, and a groove for the contact roller 39 to be stored as a whole can also be provided on the injection mold 2, so that the injection mold 2 maintains horizontal pressure contact with the support platform 31 when pressed down, and the contact roller 39 will give the support platform 31 the power to continue sliding until the support platform 31 corresponds to the lower mold 11. At this time, the stripping unit 6 is located in the sink 12, and the injection mold 2 presses the support platform 31 and the lower mold 11 to complete the injection molding of the connecting line. After the injection molding is completed, the cylinder at the bottom of the workbench 1 will push out the entire row of terminals (not shown in the figure), and the equipment of the present invention moves in the opposite direction to complete the injection molding.
