Description

Technical Field

[0001] This invention relates to the field of new energy vehicle processing technology, specifically to a welding device for new energy vehicle parts processing. Background Technology

[0002] Wiring harnesses are one of the components of new energy vehicles. When connecting these harnesses, resistance welding machines are commonly used. These machines utilize the resistance heating effect. During welding, pressure is applied to the wiring harness through electrodes, generating resistance heat at the contact points. When current flows through the pressed wires and terminal connectors, after a period of time, the contact points generate heat due to resistance, causing the metal conductors to melt and form a metallurgical bond (weld), thus achieving a strong and low-impedance electrical connection.

[0003] Currently, when welding existing new energy vehicle wiring harnesses to terminals, the operator holds one end of the wiring harness with one hand and fixes the terminal connector with the other. The terminal connector is placed on the bottom welding head of the resistance welding machine, and one end of the wiring harness is placed on the terminal connector. During the downward pressure of the top welding head, the operator releases both hands instantly, and the top and bottom welding heads perform resistance welding between the wiring harness and the terminal connector. However, during the welding process, due to the downward pressure of the top welding head, as well as the influence of the length and weight of the wiring harness, the center of gravity of the wiring harness deviates from its welding end. This causes the end of the wiring harness above the terminal connector to easily shift or even lift up from the component, resulting in increased contact resistance of the workpiece and affecting the processing and welding of new energy vehicles. To address this, we propose a welding device for new energy vehicle parts processing. Summary of the Invention

[0004] The purpose of this invention is to provide a welding device for parts processing in new energy vehicles, so as to solve the problems mentioned in the background art.

[0012] The telescopic connector includes a support member, connecting ears, a support shell, a lower pressure plate, and a pushing member. Two support members are provided, located on opposite sides inside the connection shell. Two connecting ears are provided, fixedly installed on the outside of the support shell. The support shell is located inside the connection shell and connected to the support members via the connecting ears. The lower pressure plate slides through the support shell, with a movable inclined surface on the side of the lower pressure plate near the fixed inclined surface and a pressing end on the side of the lower pressure plate outside the support shell. Two pushing members are provided, located on opposite sides inside the support shell, with grooves on the lower pressure plate corresponding to the positions of the two pushing members.

[0013] The support component includes a slide rod and a buffer spring. The slide rod is fixedly installed inside the connecting shell, and the buffer spring is sleeved on the outside of the slide rod. The top of the buffer spring is fixedly connected to the connecting shell, and the bottom of the buffer spring is fixedly connected to the connecting ear. Through the provided telescopic connector, the positioning of one end of the wire harness is achieved.

[0014] The pushing component includes a crossbar, a compression spring, and a movable ear. Both ends of the crossbar are fixedly connected to the inner wall of the groove, and the compression spring is sleeved on the outer side of the crossbar. One end of the compression spring is fixedly connected to the inner wall of the groove, and the other end of the compression spring is fixedly connected to the movable ear. The movable ear is slidably sleeved on the outer side of the crossbar, and one end of the movable spring is fixedly connected to the inner wall of the support shell. Through the provided pushing component, the function of connecting the lower pressure plate is realized.

[0015] The detection opening and closing mechanism includes a moving block, a detection element, a first limiting rod, a second limiting rod, and a telescopic element. Two moving blocks are provided, each fixedly connected to one end of a connecting rod away from the other. Both ends of each moving block are slidably connected to a limiting rail, and one end of each limiting rail is fixedly connected to a fixed seat. The detection element is installed between two sets of fixed seats. The support shell, lower pressure plate, and support block all have circular holes corresponding to the position of the detection element.

[0016] Both of the two movable blocks are rotatably connected to a connecting shaft on opposite sides. Both ends of the connecting shaft are fixedly connected to a swing rod. One end of the first limiting rod and the second limiting rod are rotatably connected to the two sets of swing rods respectively. The first limiting rod and the second limiting rod are rotatably connected to the corresponding fixed seat through the support shaft provided on them.

[0017] The telescopic component is installed on one of the fixed seats, and the telescopic component is used to push the first limiting rod;

[0018] The bottom sides of the first and second limiting rods are respectively connected to synchronous swing rods via rotating shafts. The two synchronous swing rods are located outside the insulating base. Through the provided detection opening and closing mechanism, the terminal structure positioning component and wire harness end positioning component at the two connecting rods are driven.

[0019] The detection component includes a first intermediate plate, a second intermediate plate, an infrared transmitter, and an infrared receiver. The first and second intermediate plates are respectively fixedly installed between two sets of fixed bases. The infrared transmitter is fixedly installed on the first intermediate plate, and the infrared receiver is fixedly installed on the second intermediate plate. The infrared transmitter and the infrared receiver transmit wire harness signals through a circular hole. The detection component is provided to detect whether one end of the wire harness is connected to the terminal connector.

[0020] The present invention has at least the following beneficial effects:

[0021] When this invention is used, the insulating base provided on the outside of the bottom welding head does not affect the welding of the wire harness and terminal connector by the bottom welding head and the top welding head, and at the same time facilitates the stable placement of the terminal connector above the bottom welding head.

[0022] This invention features a positioning and pressing mechanism that positions the terminal connector. After the operator places one end of the wire harness onto the terminal connector, the positioning and pressing mechanism is driven by a detection and opening / closing mechanism to further clamp and position the terminal connector and one end of the wire harness. Simultaneously, the clamping and positioning mechanism presses down on one end of the wire harness to prevent it from tilting due to its own weight. This ensures sufficient contact between the wire harness and the terminal connector, reducing contact resistance and guaranteeing stable welding between the top and bottom welding heads.

[0023] The positioning and pressing mechanism in this invention can lift the wire harness end while disengaging it from the welded end, further enabling the wire harness end to quickly detach from the bottom weld head. Attached Figure Description

Detailed Implementation

[0042] 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. Example 1

[0043] Please see Figures 1 to 2A welding device for processing parts for new energy vehicles includes a resistance welding machine body 1 for welding wire harnesses and a top welding head 2 and a bottom welding head 3 disposed on the resistance welding machine body 1. The resistance welding machine in this invention is an existing device. The bottom welding head 3 is fixedly installed on the resistance welding machine body 1, while the top welding head 2 is pressed down by a cylinder and cooperates with the bottom welding head 3 to perform resistance welding between one end of the wire harness and the terminal connector.

[0044] An insulating base 4 is fixedly sleeved on the outer side of the top of the bottom welding head 3. Two positioning and pressing mechanisms 5 are slidably connected on the insulating base 4. The positioning and pressing mechanisms 5 are used to clamp and position the terminal connector and one end of the wire harness. When passing through, the terminal connector is pressed down to prevent it from lifting while being positioned.

[0045] Please see Figures 3 to 6 and Figures 12 to 17 The positioning and pressing mechanism 5 includes a connecting rod 51, a terminal connector positioning component 52, and a wire harness end positioning component 53. The terminal connector positioning component 52 is adjustablely connected to the connecting rod 51, and the wire harness end positioning component 53 is fixedly installed at one end of the connecting rod 51.

[0046] The terminal connector positioning component 52 includes a support block 521, a clamping block 522, and a locking bolt 523. The support block 521 has a through hole and is slidably sleeved on the outside of the connecting rod 51 through the through hole. The support block 521 also has a threaded hole, and the locking bolt 523 is threadedly connected to the threaded hole. The bottom of the locking bolt 523 abuts against the connecting rod 51. In this invention, by movably connecting the clamping block 522 to the connecting rod 51, the position of the clamping block 522 can be adjusted according to the size of different types of terminal connectors, thereby ensuring that the clamping block 522 stably clamps the terminal structure.

[0047] The clamping block 522 is fixedly installed at the bottom of the support block 521. The clamping block 522 is slidably connected to the insulating base 4 and is located below the wire harness end positioning member 53.

[0048] Two clamping blocks 522 are fixedly connected to a pressing limit block 524 on the side that is close to each other. The pressing limit block 524 is arc-shaped. In this invention, when the terminal connector is placed on the bottom welding head 3, one end of the terminal connector is "pushed" into the gap between the pressing limit block 524 and the bottom welding head 3 according to the position of the two pressing limit blocks 524. This state simultaneously achieves the positioning of the terminal connector. At the same time, in the specific welding process, the shape of the pressing limit block 524 can be changed according to the shape of the terminal connector.

[0049] The wire harness end positioning component 53 includes a connecting shell 54, a positioning plate 55, and a telescopic connector 56. The connecting shell 54 is fixedly installed at one end of the connecting rod 51, and the positioning plate 55 is fixedly installed at the top inside the connecting shell 54. An opening is provided on the connecting shell 54 and on the side near the wire harness. The telescopic connector 56 passes through the opening and is connected to the connecting shell 54. A fixing slope 551 is provided at the bottom of the positioning plate 55, and the positioning plate 55 is connected to the telescopic connector 56 through the fixing slope 551.

[0050] Please see Figures 12 to 17 The telescopic connector 56 includes a support member 561, a connecting ear 562, a support shell 563, a lower pressure plate 564, and a pusher 7. There are two support members 561, which are located on both sides inside the connecting shell 54. There are two connecting ears 562, which are fixedly installed on the outside of the support shell 563. The support shell 563 is located inside the connecting shell 54 and is connected to the support member 561 through the connecting ears 562. The lower pressure plate 564 slides through the support shell 563. The side of the lower pressure plate 564 near the fixed inclined surface 551 has a movable inclined surface 5641. The side of the lower pressure plate 564 outside the support shell 563 has a lower pressure end 5642. There are two pushers 7, which are located on both sides inside the support shell 563. The lower pressure plate 564 has grooves corresponding to the positions of the two pushers 7.

[0051] The support member 561 includes a slide rod 5611 and a buffer spring 5612. The slide rod 5611 is fixedly installed inside the connecting shell 54, and the buffer spring 5612 is sleeved on the outside of the slide rod 5611. The top of the buffer spring 5612 is fixedly connected to the connecting shell 54, and the bottom of the buffer spring 5612 is fixedly connected to the connecting lug 562.

[0052] Please see Figures 16 to 17 The pusher 7 includes a crossbar 71, a compression spring 72, and a movable ear 73. Both ends of the crossbar 71 are fixedly connected to the inner wall of the groove, and the compression spring 72 is sleeved on the outside of the crossbar 71. One end of the compression spring 72 is fixedly connected to the inner wall of the groove, and the other end of the compression spring 72 is fixedly connected to the movable ear 73. The movable ear 73 is slidably sleeved on the outside of the crossbar 71, and one end of the movable arm is fixedly connected to the inner wall of the support shell 563.

[0053] Specific implementation process: The worker places the terminal connector on the bottom welding head 3, while two limiting blocks position the bottom welding head 3. Then, the worker places the wire harness end on the terminal connector with their other hand, and the lower limiting block 524 simultaneously limits the wire harness end. As the two connecting rods 51 move towards each other, they simultaneously drive the two clamping plates and two connecting shells 54 to move towards each other. The two clamping plates further clamp and position the wire harness connector. During this movement, the lowering ends 5642 of the two lowering plates 564 first contact one end of the wire harness connector. Upon contact, the lowering plates 564 are simultaneously limited by the wire harness connector. Further, the lowering plates 564 retract along the inside of the support shell 563. As the plate 564 retracts, the moving inclined surface 5641 inside the lower pressure plate 564 contacts the fixed inclined surface 551 at the bottom of the positioning plate 55. Under the limiting action of the fixed inclined surface 551, the lower pressure plate 564 guides the downward pushing force of the fixed inclined surface 551 to the support shell 563. Then, under the support of the sliding rods 5611 on both sides and the buffer springs 5612, the support shell 563 further drives the lower pressure plate 564 to move downward along the inside of the connecting shell 54, thereby pressing the lower pressure plate 564 down relative to the wire harness end, thus providing downward pressure to the wire harness end and preventing the wire harness end from lifting or deviating from the terminal connector, thereby ensuring that the terminal connector and the wire harness end are stably welded through the bottom welding head 3 and the top welding head 2.

[0054] Simultaneously, after welding is completed, as the two connecting shells 54 move away from each other, the two lower pressure plates 564 simultaneously lift the wire harness ends, thereby enabling the welded wire harness ends to quickly detach from the bottom welding head 3, thus preventing adhesion.

[0055] Please see Figures 3 to 11 An insulated base 4 is equipped with a detection opening and closing mechanism 6 for synchronously driving two positioning pressing mechanisms 5. The detection opening and closing mechanism 6 includes a moving block 61, a detection element 62, a first limiting rod 63, a second limiting rod 64, and a telescopic element 65. There are two moving blocks 61, which are fixedly connected to the ends of the two connecting rods 51 that are far apart from each other. Both ends of the moving blocks 61 are slidably connected to limiting rails 66, and one end of the limiting rails 66 is fixedly connected to a fixed seat 67. The detection element 62 is installed between the two sets of fixed seats 67. The support shell 563, the pressing plate 564, and the support block 521 are all provided with round holes corresponding to the position of the detection element 62.

[0056] Two movable blocks 61 are rotatably connected to a connecting shaft 68 on opposite sides. Both ends of the connecting shaft 68 are fixedly connected to a swing rod 69. One end of the first limiting rod 63 and the second limiting rod 64 are rotatably connected to the two sets of swing rods 69 respectively. The first limiting rod 63 and the second limiting rod 64 in this invention are irregularly shaped. The first limiting rod 63 and the second limiting rod 64 are rotatably connected to the corresponding fixed seat 67 through the support shaft 631 provided on them respectively.

[0057] The telescopic member 65 is installed on one of the fixed seats 67, and the telescopic member 65 is used to push the first limiting rod 63;

[0058] The bottom sides of the first limiting rod 63 and the second limiting rod 64 are respectively connected to synchronous swing rods 8 via rotating shafts, and the two synchronous swing rods 8 are located outside the insulating base 4.

[0059] The detection component 62 includes a first intermediate plate 621, a second intermediate plate 622, an infrared transmitter 623, and an infrared receiver 624. The first intermediate plate 621 and the second intermediate plate 622 are respectively fixedly installed between two sets of fixing seats 67. The infrared transmitter 623 is fixedly installed on the first intermediate plate 621, and the infrared receiver 624 is fixedly installed on the second intermediate plate 622. The infrared transmitter 623 and the infrared receiver 624 transmit the wire harness signal through the circular hole.

[0060] Specific implementation process: In this invention, the infrared transmitter 623 and infrared receiver 624 are used to detect whether terminal connectors and wire harness ends are placed. After a certain period of time, the controller sends a signal to the telescopic member 65, causing the telescopic member 65 to move. This causes the first limiting rod 63 to rotate around the support shaft 631. Simultaneously, the first limiting rod 63 rotates, and one end of it synchronously drives two synchronous swing rods 8 to move. While the two synchronous swing rods 8 are moving, the second limiting rod 64 is further moved through the support shaft 631. The support shaft 631 rotates relative to the fixed seat 67 on it. At this time, the first limiting rod 63 and the second limiting rod 64 move synchronously, further driving the swing rod 69. The swing rod 69 then drives the moving block 61 to move. At this time, the two moving blocks 61 are limited by the limiting rails 66 on both sides, which causes the two moving blocks 61 to drive the connecting shell 54 on them to move towards each other until the wire harness end and the terminal connector are clamped and positioned. Then, the top welding head 2 can be pressed down and cooperated with the bottom welding head 3 to achieve resistance welding of the wire harness end and the terminal connector. Example 2

[0061] Please see Figure 10Example 2 further supplements the description of the telescopic component 65 in Example 1. Specifically, the telescopic component 65 includes a side plate 651, a positioning shaft 652, an electric push rod 653, a push seat 654, and a push plate 655. There are two side plates 651, which are respectively fixedly installed on two of the fixed seats 67. The two ends of the positioning shaft 652 are fixedly connected to the two side plates 651. The electric push rod 653 is rotatably connected to the positioning shaft 652, and the output end of the electric push rod 653 is fixedly connected to the push seat 654. The push seat 654 is fixedly connected to the push plate 655 through a pin, and the push plate 655 is fixedly installed on the first limit rod 63.

[0062] Specifically: When the first limiting rod 63 is pushed, the electric push rod 653 extends or retracts, further causing the first limiting rod 63 to rotate around the support shaft 631. While the first limiting rod 63 is rotating, it drives a set of swing rods 69 and two synchronous swing rods 8 to rotate, thereby realizing the linkage of the second limiting rod 64 and pushing the connecting shell 54.

[0063] Meanwhile, in this invention, the electric push rod 653 is positioned away from the bottom welding head 3 and the top welding head 2, so that the electric push rod 653 is not affected during welding.
