Description

Technical Field

[0001] This utility model relates to the technical field of automotive connector processing equipment, specifically to a pin bending device for automotive connectors. Background Technology

[0002] In the automotive electronics field, automotive connectors are key components for circuit connections, and the bending accuracy of their pins directly affects the connector's assembly quality and electrical performance. Currently, the industry mostly uses manual bending or step-by-step bending of individual pins for bending automotive connector pins.

[0003] Manual bending relies heavily on the operator's experience and skill, resulting in high labor intensity, low production efficiency, and difficulty in ensuring consistent bending angles, especially for rows of terminals, which are prone to bending deviations and pin deformation, leading to a lower product qualification rate. Furthermore, manual operation suffers from poor stability and is significantly affected by human factors, failing to meet the demands of large-scale, automated production in the automotive manufacturing industry.

[0004] Therefore, there is an urgent need for an automated device that can bend a row of pins at once to improve production efficiency, ensure product quality, and reduce production costs. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0033] This utility model provides a pin bending device for an automotive connector.

[0034] In this embodiment, refer to Figure 1-5 The pin bending device of the automotive connector includes a bracket, a clamping mechanism, a positioning mechanism, and a bending mechanism;

[0035] The support includes a base plate 1 and a horizontal plate 3 fixed above the base plate 1 by a column 2;

[0036] The clamping mechanism includes a pressing drive 4 fixed on the horizontal plate 3, a connector clamping block 5 and a pin clamping plate 6 connected to the output end of the pressing drive 4;

[0037] The positioning mechanism includes a positioning drive 7 and a positioning module 8 connected to the output end of the positioning drive. The positioning module 8 is provided with a connection structure for positioning the car connector on the positioning module.

[0038] The bending mechanism includes a folding plate 9 and a rotary drive mechanism for driving the folding plate 9 to bend the pins 11 of the automotive connector 10.

[0039] In the above technical solution, the pressing mechanism's pressing drive drives the connector pressing block and the pin pressing plate. The connector pressing block can firmly press the car connector housing, while the pin pressing plate can press the entire row of pins of the car connector. The positioning mechanism's positioning drive drives the positioning module, which uses the connecting structure to move the car connector to the appropriate position. The bending mechanism's rotation drive drives the folding plate to rotate, which is used to bend the pins of the pressed car connector, thereby realizing the automated bending of the car connector pins.

[0040] By adopting the above solution, a row of terminals on the automotive connector can be bent in one go, changing the traditional manual or step-by-step bending method, greatly improving product production efficiency, reducing labor costs, and ensuring the accuracy and consistency of pin bending through precise positioning and clamping, thereby improving product quality.

[0041] The specific principle is as follows: Figure 5 As shown, after the automotive connector is pressed and fixed, the folding plate is rotated and folded by the rotary drive mechanism, bending the rows of pins.

[0042] Specifically, the rotary drive mechanism includes a bending drive component 12, a rack 13 connected to the output end of the bending drive component, a driven gear 14 meshing with the rack 13, bearing seats 15 disposed on both sides of the folding plate, a rotating shaft 16 rotatably connected to the bearing seats 15, a connecting block 37 and a plate frame 17 connected to the rotating shaft 16, and the folding plate is fixed on the plate frame.

[0043] In this embodiment, in the rotary drive mechanism, the bending drive component drives the spur rack to move, and the spur rack meshes with the driven gear to drive the driven gear to rotate, which in turn drives the rotating shaft connected to the driven gear to rotate. The rotating shaft drives the folding plate to move through the plate frame, and the bearing seat provides stable rotational support for the rotating shaft, so as to realize the bending action of the folding plate on the pin.

[0044] Specifically, the rack has positioning blocks 18 at both ends, the rack slides in fit with the rack holes 19 of the positioning blocks 18, and a protruding limiting block 20 is provided on one side of the rack.

[0045] In this embodiment, the positioning blocks at both ends of the rack guide the rack, allowing it to slide within the rack holes of the positioning blocks, thus restricting its direction of movement. A limiting block on one side of the rack can cooperate with other components to limit its travel. This prevents the rack from deviating or wobbling during movement, ensuring the stability of the meshing between the rack and the driven gear. Simultaneously, the limiting blocks precisely control the rack's range of motion, preventing excessive bending of the pins or damage to the mechanism due to excessive rack movement, thereby improving the safety and reliability of the device.

[0046] Specifically, the pressing drive, positioning drive, and bending drive are all pneumatic cylinders or electric cylinders.

[0047] In this embodiment, the pressing drive, positioning drive, and bending drive are pneumatic or electric cylinders, which use air pressure or electricity to drive linear motion and provide power for the operation of each mechanism.

[0048] Specifically, the connection structure includes a lower positioning groove 21, a lower positioning step 22, a lower positioning slot 23, and an end positioning step 24 on the positioning module. The outer shell of the automotive connector is provided with an upper positioning protrusion 25, an upper positioning groove 26, and an upper positioning protrusion 27 that are adapted and connected to the lower positioning groove, the lower positioning step, and the lower positioning slot, respectively. The end positioning step abuts against the end of the outer shell of the automotive connector.

[0049] In this embodiment, the connection structure, through the lower positioning groove, lower positioning step, lower positioning slot opening, and end positioning step on the positioning module, adapts and abuts against the upper positioning protrusion, upper positioning groove, upper positioning protrusion, and end of the automotive connector housing, forming a multi-directional positioning constraint. This ensures that the automotive connector is firmly and accurately positioned on the positioning module, preventing displacement or shaking of the automotive connector during pin bending, ensuring the accuracy of pin bending, and reducing the product defect rate caused by inaccurate positioning.

[0050] Specifically, guide blocks 28 and guide plates 29 are fixed on both sides of the positioning module, and guide grooves 30 are formed between the guide blocks and guide plates to slide and cooperate with both sides of the positioning module.

[0051] In this embodiment, the guide blocks and guide plates on both sides of the positioning module form a guide groove, and the positioning module slides in the guide groove. The guide groove guides and constrains the movement of the positioning module.

[0052] Specifically, the connector pressure block has a positioning notch 31 at its bottom, and the car connector housing has a positioning protrusion 32 that matches the positioning notch 31.

[0053] In this embodiment, the positioning notch at the bottom of the connector clamping block matches the positioning protrusion on the automotive connector housing. During the clamping process, the two cooperate to form a positioning constraint. This further improves the clamping and positioning accuracy of the connector clamping block on the automotive connector, prevents the automotive connector from rotating or shifting during the clamping process, ensures that the pins are in the correct position when bent, and improves the accuracy of pin bending.

[0054] Specifically, a fixing plate 38 is fixed between the output end of the pressure drive component and the connector pressure block and the pin pressure plate. A guide post 33 is provided at the upper end of the fixing plate, and the guide post slides in conjunction with the guide hole 34 on the horizontal plate.

[0055] In this embodiment, the output end of the downward driving component is connected to the connector clamping block and the pin clamping plate via a fixed plate. The guide post on the fixed plate slides within the guide hole of the horizontal plate, providing guidance for the movement of the fixed plate. This ensures the stability and straightness of the connector clamping block and the pin clamping plate during their up-and-down movement, preventing them from tilting or shifting, ensuring a uniform and consistent clamping effect on the automotive connector, and improving the stability of pin bending.

[0056] Specifically, a limiting strip 35 is fixed on the horizontal plate, and a limiting step 36 is provided on the limiting strip 35. When the fixed plate moves upward, the limiting step 36 can abut against the outer edge of the fixed plate.

[0057] In this embodiment, the limiting strip on the horizontal plate abuts against the outer edge of the fixed plate through the limiting step. When the fixed plate moves upward to a certain position, the limiting step restricts the fixed plate from continuing to move upward, thus limiting the movement and preventing the fixed plate from moving too far upward.

[0058] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
