Description

Technical Field

[0001] This invention relates to the field of crimping testing technology, specifically to an integrated device for crimping testing of fisheye terminal connectors for airbag controllers. Background Technology

[0002] The fisheye terminal connector for airbag controllers is a critical connection component in automotive electronic safety systems, and its crimping quality directly affects the reliability of airbag trigger signal transmission. Existing fisheye terminal connector crimping equipment typically employs a fixed crimping head structure. The pressing surface of the crimping head remains in a fixed downward orientation throughout the entire operation of the equipment. A drive mechanism drives the crimping head to press vertically downwards to complete the embedding connection between the terminal and the substrate.

[0003] However, because the pressing surface of the pressing head of the existing crimping device is always fixed downwards, small impurities or debris on the surface of the workpiece are easily and firmly adhered to the pressing surface under the strong crimping force during the crimping process. Since the pressing surface is always downwards, the operator cannot see the pressing surface directly from the front or from the side or above during equipment operation breaks. As a result, impurities remain on the pressing surface for a long time and participate in subsequent crimping operations. This can cause abnormal crimping depth and poor terminal contact, or even lead to unqualified crimping quality of batch products, posing a serious risk to product consistency. There is an urgent need for a crimping device whose pressing surface can automatically rotate back to face the operator after crimping, so that the operator can promptly detect and clean the adhering impurities on the pressing surface, fundamentally eliminating the above-mentioned quality risks.

[0016] Beneficial effects

[0017] Compared with the prior art, the present invention provides an integrated device for testing the crimping of the fisheye terminal connector of an airbag controller, which has the following advantages:

[0018] 1. This integrated crimping and testing device for a fisheye terminal connector of an airbag controller utilizes a crimping mechanism. After crimping, the crimping plate automatically rotates back to its initial state with the crimping surface facing forward. This allows operators to directly observe the crimping surface and promptly detect and clean any impurities that adhere to it due to the crimping force during the crimping process. This prevents impurities from remaining and causing quality issues in subsequent crimped products. It solves the problem that the crimping head of existing crimping devices always faces downwards, making it difficult for operators to directly observe the crimping surface and detect adhering impurities in a timely manner.

[0019] 2. This integrated device for crimping and testing of fisheye terminal connectors for airbag controllers utilizes a reciprocating mechanism. When the drive head moves downward, the ring block drives the elastic rope through the guide roller to turn, converting the vertical motion into horizontal tension, which automatically drives the placement plate to move backward to the crimping station directly below the pressure testing plate. After crimping is completed, the return spring releases the elastic potential energy, driving the placement plate to move forward and reset automatically. The entire movement of the workpiece station is automatically linked with the crimping action, eliminating the safety hazards of manual feeding by eliminating the need for operators to put their hands under the pressure testing plate for loading and unloading.

[0020] 3. This integrated device for crimping and testing of fisheye terminal connectors for airbag controllers utilizes a clamping mechanism. During the backward movement of the placement plate, the inclined surface of the trapezoidal guide block presses against the adjusting screw, driving the sealing strip to compress air within the hollow groove. The pressurized gas simultaneously acts on multiple arrayed sealing cylindrical blocks, causing each actuator to extend synchronously to perform multi-point clamping and positioning of the fisheye terminal connector. After crimping is completed, a lightweight spring drives the actuator to automatically retract and release the workpiece. This achieves automatic linkage between workpiece clamping and placement plate displacement, ensuring the positioning stability of the workpiece during crimping without the need for additional clamping actions.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-11An integrated device for crimping and testing fisheye terminal connectors of airbag controllers includes: a base 1, a support shaft 2 fixedly connected to the top of the base 1, a support box 3 fixedly connected to the top of the support shaft 2, a pressure testing mechanism 4 disposed on the support box 3 and the base 1, the pressure testing mechanism 4 including: a drive head 42, a rigid shaft 44 rotatably connected to the inner wall of the drive head 42, a connector 45 fixedly connected to the rigid shaft 44, and a pressure testing plate 46 fixedly connected to the side of the connector 45 away from the rigid shaft 44. The pressure testing plate 46 is used for crimping the fisheye terminal connector, and a detection sensor is disposed inside the pressure testing plate 46 for real-time monitoring during the crimping process. An adjustment mechanism is fixedly connected to the end of the rigid shaft 44. Gear 47, and an adjusting rack 48 are fixedly connected to the bottom of the support box 3. The tooth surface of the adjusting rack 48 is meshed with the adjusting gear 47 in the initial state. A guide rod 412 is fixedly connected to the pressing surface of the pressure plate 46. A placement plate 411 is provided on the base 1 for placing the fisheye terminal connector to be crimped and tested. A guide groove 413 is provided on the placement plate 411. When the pressure plate 46 is pressed down, it drives the guide rod 412 to insert into the guide groove 413 for further guidance and positioning. First, the drive head 42 moves downward in a straight line. The drive head 42 drives the connector 45, the pressure plate 46 and the adjusting gear 47 to move down synchronously through the rigid shaft 44 rotatably connected to its inner wall. In the initial stage of downward movement In the first section, the adjusting gear 47 fixed to the end of the rigid shaft 44 is engaged with the adjusting rack 48 fixed to the bottom of the support box 3. As the drive head 42 moves, the adjusting rack 48 forces the adjusting gear 47 to rotate, thereby driving the rigid shaft 44 and the pressure plate 46 at its end to adjust to the predetermined pressing angle during the falling process, so that the pressing surface of the pressure plate 46 faces downward. When the pressure plate 46 continues to approach the placement plate 411 located above the base 1, the guide rod 412 fixed to the pressing surface of the pressure plate 46 is first inserted into the guide groove 413 opened on the placement plate 411. The physical pin structure realizes secondary precise guidance and positioning before pressing. Then the pressure plate 46 acts vertically on the placement plate 411. The fisheye terminal connector on the placement plate 411 completes the crimping action. Simultaneously, a detection sensor installed inside the pressure testing plate 46 collects pressure data in real time during the crimping process, thus achieving synchronized and integrated operation of crimping and quality inspection. The frame structure formed by the support shaft 2 and the support box 3 ensures the mechanical stability of the entire crimping stroke. The reciprocating mechanism 5, mounted on the base 1, drives the placement plate 411 to move backward below the pressure testing plate 46 when the pressure testing plate 46 moves downward. The clamping mechanism 6, mounted on the placement plate 411, is used to position and clamp the fisheye terminal connector when the placement plate 411 moves backward. Four support shafts 2 are provided, symmetrically arranged in pairs between the support box 3 and the base 1, using four-point support to construct a stable gantry-type frame space.This symmetrical structure effectively disperses the vertical reaction force generated during the pressing process, preventing the support box 3 from tilting or vibrating slightly under pressure, thus ensuring the structural strength and alignment accuracy of the entire pressing mechanism 4 under long-term, high-frequency operation. A drive component 41 is installed on the inner wall of the support box 3, and a drive head 42 is fixedly connected to the output end of the drive component 41. Upon receiving a command, the drive component 41 extends and retracts, forcibly driving the drive head 42 to move precisely in a vertical linear reciprocating motion. As the main power source of the entire machine, it provides the necessary downward pressure for subsequent rotational adjustment and final pressing. The drive head 42 is slidably connected to the vertical guide rail 43, which is fixedly connected to the support box 3. A bearing is installed between the inner wall of the drive head 42 and the rigid shaft 44. The inner ring of the bearing is fixedly connected to the rigid shaft 44, and the outer ring of the bearing is fixedly connected to the inner wall of the drive head 42. This utilizes rolling or sliding friction pairs to eliminate horizontal wobbling and ensure the straightness of the pressing stroke. Simultaneously, the bearing embedded between the drive head 42 and the rigid shaft 44 effectively transmits the linear thrust of the drive head 42 to the rigid shaft 44 through the relative movement of the inner and outer rings of the bearing, while significantly reducing the frictional resistance of the rigid shaft 44 when driven by the rack and pinion. This not only improves the rotational sensitivity but also extends the service life of key rotating components. A first magnetic block 49 is fixedly connected to the pressure plate 46, and a second magnetic block 410 is fixedly connected to the bottom inner wall of the drive head 42. The initial position of the pressing surface of the pressure plate 46 is in the front. At this time, the first magnetic block 49 and the second magnetic block 410 do not attract each other. Until the pressing surface of the pressure plate 46 rotates to the bottom, the pressure plate 46 drives the first magnetic block 49 to rotate to the bottom of the drive head 42, so that the first magnetic block 49 and the second magnetic block 410 attract each other and form a preliminary pre-position. In the initial state, the pressing surface of the pressure plate 46 faces the front for easy sensor maintenance or material observation. At this time, the first magnetic block 49 and the second magnetic block 410 are in a separated state. When the drive head 42 moves down and drives the adjusting gear 47 to roll on the adjusting rack 48, the rigid shaft 44 rotates to a preset angle, so that the pressure plate 46 turns from the front to directly downward. At this point, the adjusting gear 47 and the adjusting rack 48 are no longer engaged, and the first magnetic block 49, fixed on the pressure plate 46, rotates to the bottom of the drive head 42 and forms a strong magnetic attraction with the second magnetic block 410. The ingenuity of this design lies in using magnetic attraction to achieve initial locking, eliminating rotational gaps before the pressure plate 46 contacts the workpiece, forming a stable pre-position, and preventing damage to the terminals caused by torsional force generated during pressing.

[0035] The reciprocating mechanism 5 includes an annular block 51, which is rotatably connected to the middle of the rigid shaft 44. An elastic rope 52 is mounted on the annular block 51, with one end fixedly connected to the annular block 51 and the other end fixedly connected to a positioning plate 54. The positioning plate 54 is fixedly connected to the bottom of the placement plate 411. A linear guide rail 53 is fixedly connected to the top of the base 1, and the top of the linear guide rail 53 is slidably connected to the placement plate 411. A return spring 58 is provided between the second limiting block 57 and the positioning plate 54. One end of the return spring 58 is fixedly connected to the second limiting block 57, and the other end is fixedly connected to the positioning plate 54. When the drive head 42 drives the rigid shaft 44 downwards, the annular block 51, rotatably connected to the middle of the rigid shaft 44, moves downwards synchronously. Since the elastic rope 52 is fixedly connected to the annular block 51, and the other end of the elastic rope 52 is fixed to the positioning plate 411... As the ring block 51 presses down on the positioning plate 54 at the bottom, the elastic rope 52 is tightened and generates tension. This tension acts on the positioning plate 54 and drives the placement plate 411, which is fixedly connected to it, to slide on the linear guide rail 53 at the top of the base 1 to the bottom of the pressure testing plate 46. During this process, the second limiting block 57 fixed on the placement plate 411 moves and stretches the return spring 58 set between the second limiting block 57 and the positioning plate 54, so that the return spring 58 generates elastic potential energy. When the pressing test task is completed and the drive head 42 drives the rigid shaft 44 to rise and reset, the tension of the elastic rope 52 on the positioning plate 54 disappears. At this time, the return spring 58 releases elastic potential energy, pushes the second limiting block 57 to drive the entire placement plate 411 to slide in the opposite direction along the linear guide rail 53, so that the placement station returns to the initial waiting state, so that the workers do not need to place their hands on the bottom of the pressure testing plate 46 to work.A guide roller 55 is provided on the top of the base 1, and the elastic rope 52 is guided and driven through the guide roller 55. A first limiting block 56 and a second limiting block 57 are provided on the top of the base 1. The first limiting block 56 is located at the rear of the placement plate 411, and the second limiting block 57 is located at the front of the placement plate 411. When the drive head 42 moves downward, driving the rigid shaft 44 and the annular block 51 downward, the elastic rope 52 is pulled. At this time, the elastic rope 52 bypasses the guide roller 55 fixed on the top of the base 1 for steering transmission, efficiently converting the vertical tension into the horizontal tension, thereby pulling the placement plate 411 to slide horizontally. During the sliding process, the travel of the placement plate 411 is physically limited: when the placement plate 411 moves backward to the predetermined pressing position, its front part will touch the first limiting block 56 fixed on the base 1, and the backward stop is achieved by the blocking of the first limiting block 56, ensuring that the pressing station stops directly below the pressing plate 46; when the pressing is completed, the drive head 42 rises and the return spring 58 drives the placement plate 411 to reset, the rear part of the placement plate 411 will touch the second magnetic block 410 fixed on the base 1, and the forward stop is achieved by the blocking of the second magnetic block 410, so that the device accurately returns to the initial waiting position.

[0036] The clamping mechanism 6 includes a trapezoidal guide block 61 and a hollow plate 62. The trapezoidal guide block 61 is fixedly connected to the top of the base 1. Two trapezoidal guide blocks 61 are symmetrically arranged. A mounting seat 63 is provided at the bottom of the hollow plate 62. A mounting groove is opened on the placement plate 411. The mounting seat 63 is installed in the mounting groove on the placement plate 411, so that the top of the mounting seat 63 is flush with the surface of the placement plate 411. A hollow groove 64 and a sealing groove 65 are opened on the inner wall of the hollow plate 62. Several sealing grooves 65 are arranged in an array. The sealing grooves 65 are connected to the hollow grooves 64. A sealing strip 66 is piston-connected to the inner wall of the hollow groove 64. The side of the sealing strip 66 away from the sealing groove 65 is threaded. An adjusting screw 67 is connected to the hollow plate 62. An actuating shaft 68 is piston-connected to the inner wall of the hollow plate 62. A sealing cylindrical block 69 is fixedly connected to one end of the actuating shaft 68, and an actuating button 610 is fixedly connected to the other end of the actuating shaft 68. The sealing cylindrical block 69 is piston-connected to the inner wall of the sealing groove 65. A light spring 611 is provided between the sealing cylindrical block 69 and the inner wall of the sealing groove 65. When the placement plate 411 slides backward along the linear guide rail 53, the mounting seat 63 fixed in the mounting groove of the placement plate 411 synchronously drives the hollow plate 62 to move backward, so that the adjusting screw 67 located on the outside of the hollow plate 62 and connected by the sealing strip 66 is inclined to the trapezoidal guide block 61 fixed on the top of the base 1. When physical contact occurs between the surfaces, as the displacement continues, the inclined surface of the trapezoidal guide block 61 generates an inward squeezing force, forcing the adjusting screw 67 to move closer to the sealing groove 65. This, in turn, drives the sealing strip 66, which is threadedly connected to it, to perform a piston-like movement within the hollow groove 64. The sealing strip 66 compresses the air within the cavity of the hollow groove 64, forcing the compressed air to enter the sealing groove 65 through the connecting hole and exert pressure on the sealing cylindrical block 69. The compressed sealing cylindrical block 69 overcomes the elastic force of the light spring 611 and moves outward. Through the fixedly connected actuator shaft 68, it drives the end actuator block 610 to extend towards the workpiece, ultimately achieving the pressing and fixing of the fisheye terminal connector placed on the workstation. When the pressing is completed and the placement plate 411 returns to its forward position, the adjusting screw 67 disengages from the trapezoidal guide block 61. Under the restoring force of the lightweight spring 611, the pressure in the entire air circuit is released, the actuator block 610 retracts, and the workpiece is automatically released. Due to the array and interconnection of the sealing grooves 65, the air pressure generated by the hollow groove 64 can act simultaneously on multiple sealing cylindrical blocks 69, ensuring multi-point synchronous clamping of the workpiece and enhancing the positioning stability during the pressing process. The threaded connection design between the adjusting screw 67 and the sealing strip block 66 allows the operator to fine-tune the initial gap by rotating the screw according to the size of different models of connectors, thereby precisely controlling the final clamping stroke and air compression ratio. One end of the lightweight spring 611 is fixedly connected to the inner wall of the sealing groove 65, and the other end of the lightweight spring 611 is fixedly connected to the sealing cylindrical block 69. The function of the lightweight spring 611 is to provide reverse power for the mechanism.Since pneumatic transmission often has residual pressure or response lag after the extrusion source is lost, the mechanical rebound force of the spring can ensure that the actuator 610 retracts instantly in the non-operation state, avoiding interference with the subsequent unloading or loading process.

[0037] In summary, this integrated device for crimping and testing of fisheye terminal connectors for airbag controllers is used in the following steps: First, the operator places the fisheye terminal connector to be crimped and tested on the surface of the placement plate 411. At this time, the placement plate 411 is in its initial waiting position, abutting against the second limit block 57, and the entire device is in a static, ready state. Then, the drive unit 41 receives a start command, and its output end extends, driving the drive head 42, which is fixedly connected to it, to move downwards in a precise linear motion along the vertical guide rail 43 fixed on the support box 3. The vertical guide rail 43 constrains the direction of movement of the drive head 42, preventing lateral deviation. Simultaneously, as the drive head 42 moves downwards, it drives the bearing through the outer ring of its inner wall bearing. The inner ring, in turn, drives the rigid shaft 44, which is fixedly connected to the inner ring of the bearing, to move downwards synchronously. The bearing's function is to transmit linear thrust while allowing the rigid shaft 44 to rotate freely relative to the drive head 42. During the downward movement of the rigid shaft 44, the adjusting gear 47, fixedly connected to its end, moves downwards accordingly. Since the adjusting gear 47 is initially engaged with the adjusting rack 48 fixed to the bottom of the support box 3, the teeth of the adjusting rack 48 exert a tangential constraint force on the adjusting gear 47, forcing the adjusting gear 47 to rotate while moving downwards. The function of the adjusting rack 48 is to convert the linear displacement of the rigid shaft 44 into rotational motion, controlling the rotation angle of the pressure plate 46. The rotation of the adjusting gear 47 drives the rigid shaft 44 to rotate synchronously. The rotation of the rigid shaft 44 is transmitted to the pressure plate 46 through the fixedly connected connector 45, causing the pressure plate 46 to gradually rotate from its initial pressing surface facing forward to a predetermined pressing angle with the pressing surface facing downward. The function of the connector 45 is to rigidly transmit the rotational motion of the rigid shaft 44 to the pressure plate 46. When the pressure plate 46 has rotated to its position, the adjusting gear 47 disengages from the adjusting rack 48. Simultaneously, the first magnetic block 49 fixed on the pressure plate 46 rotates with the pressure plate 46 to the bottom inner wall of the drive head 42, where it attracts the second magnetic block 410 fixed on the bottom inner wall of the drive head 42. The magnetic attraction between the first magnetic block 49 and the second magnetic block 410 eliminates rotational clearance, locks the angle of the pressure plate 46, and prevents... The moment of crimping generates a torsional force that damages the terminal; at the same time, when the rigid shaft 44 moves downward, the annular block 51 rotatably connected to the middle of the rigid shaft 44 moves downward synchronously. The annular block 51 pulls the elastic rope 52 downward through the elastic rope 52 fixedly connected to it. The elastic rope 52 turns around the guide roller 55 fixed to the top of the base 1. The function of the guide roller 55 is to convert the vertical tension of the elastic rope 52 into a horizontal tension. The horizontal elastic rope 52 pulls the positioning plate 54 fixedly connected to the bottom of the placement plate 411. The positioning plate 54 drives the placement plate 411 to slide horizontally backward on the linear guide rail 53 at the top of the base 1. The function of the linear guide rail 53 is to constrain the movement trajectory of the placement plate 411 and ensure that it slides backward in a straight line.When the placement plate 411 slides backward to the predetermined position, it touches the first limiting block 56 fixed on the base 1. The function of the first limiting block 56 is to stop the placement plate 411 backward, so that the placement plate 411 stops precisely below the pressure testing plate 46. At the same time as the placement plate 411 moves backward, the mounting seat 63 fixed in the mounting groove of the placement plate 411 drives the hollow plate 62 to move backward synchronously. The adjusting screw 67 on the outside of the hollow plate 62 makes physical contact with the inclined surface of the trapezoidal guide block 61 fixed on the top of the base 1. There are two trapezoidal guide blocks 61 symmetrically arranged, and their function is to guide the placement plate 411 backward. During the process, an inward compressive force is applied to the adjusting screw 67; after being squeezed inward by the inclined surface of the trapezoidal guide block 61, the adjusting screw 67 moves inward, driving the sealing strip 66, which is threaded to it, to make a piston-like movement inward within the hollow groove 64 on the inner wall of the hollow plate 62. The sealing strip 66 compresses the air in the hollow groove 64. The threaded connection between the adjusting screw 67 and the sealing strip 66 allows the operator to pre-adjust the clamping stroke; the compressed air enters the arrayed sealing grooves 65 through the connecting holes in the hollow groove 64, generating air pressure on the sealing cylindrical block 69, which is piston-connected within the sealing groove 65. The sealing cylindrical block 69 overcomes the light elasticity. The spring 611 moves outward due to its elastic force. One end of the lightweight spring 611 is fixed to the inner wall of the sealing groove 65, and the other end is fixed to the sealing cylindrical block 69. Its function is to provide a restoring force after the air pressure disappears. The sealing cylindrical block 69 moves outward, which drives the end of the execution block 610 to extend towards the workpiece through the fixedly connected execution shaft 68. Multiple sealing grooves 65 are pressed at the same time, causing multiple execution blocks 610 to extend synchronously, performing multi-point synchronous pressing and positioning on the fisheye terminal connector placed at the workstation, enhancing the positioning stability during the crimping process. After the clamping and positioning is completed, the drive head 42 continues to drive the rigid shaft 44 and the pressure plate 46. The guide rod 412, fixed on the pressing surface of the pressure plate 46, moves vertically downwards and is first inserted into the guide groove 413 opened on the placement plate 411. The function of the guide rod 412 and the guide groove 413 is to achieve secondary precise guidance and positioning before crimping, and to prevent lateral displacement between the pressure plate 46 and the fisheye terminal connector. Then, the pressing surface of the pressure plate 46 acts vertically downwards on the fisheye terminal connector to complete the crimping action. The detection sensor installed inside the pressure plate 46 collects pressure data in real time during the crimping process. The function of the detection sensor is to simultaneously monitor the crimping quality and realize the integrated operation of crimping and detection.After the crimping test is completed, the drive component 41 retracts in the reverse direction, driving the drive head 42 to reset upwards along the vertical guide rail 43. The rigid shaft 44 and the annular block 51 move upwards accordingly, and the horizontal tension of the elastic rope 52 on the positioning plate 54 disappears. At this time, the return spring 58 set between the second limit block 57 and the positioning plate 54 releases the elastic potential energy stored when it was stretched, pushing the second limit block 57 to drive the placement plate 411 to reset and slide forward along the linear guide rail 53. The placement plate 411 moves forward and stops when its rear touches the second limit block 57. The function of the return spring 58 is to drive the placement plate 411 to automatically return to the initial waiting position. This eliminates the need for operators to reach under the pressure plate 46 for unloading. Simultaneously, as the placement plate 411 moves forward and resets, the mounting base 63 moves the hollow plate 62 forward, the adjusting screw 67 disengages from the inclined surface of the trapezoidal guide block 61, the air pressure in the sealing groove 65 disappears, and the reset force of the lightweight spring 611 pushes the sealing cylindrical block 69 inward. The sealing cylindrical block 69, through the actuator shaft 68, drives the actuator button 610 to retract, automatically releasing the clamp on the fisheye terminal connector. The operator can then remove the workpiece that has undergone crimping testing and place a new workpiece to be tested. The device returns to its initial waiting state, ready for the next cycle.
