Description

Technical Field

[0001] This utility model relates to the field of sensor lead wire welding, and more specifically, to an integrated machine for automatic welding and testing of sensor leads. Background Technology

[0002] The welding and inspection integrated machine is a device used in the sensor production process to automatically perform lead wire welding and weld quality inspection. This type of machine typically integrates multiple functions such as welding, inspection, control, and display, which can significantly improve production efficiency, ensure consistent weld quality, and reduce errors caused by manual operation.

[0003] A search revealed that Chinese patent CN219684343U discloses a "welding inspection integrated machine," comprising a frame with vertical rods and fixing components mounted on them. These fixing components are used to mount support plates, which house an electronic control system, a system host, and an integrated laser. The system host connects to an in-mold inspection module and an in-mold welding unit. A touchscreen display is mounted at the front of the frame, and a control button panel is located below the touchscreen display. A worktable is located below the control button panel. This invention places the electronic control system, system host, and integrated laser within the frame, allowing the equipment to operate outside the mold without interference, providing dust and oil protection. The fixing components and support plates facilitate the placement of the electronic control system, system host, and integrated laser. The distance between the upper and lower support plates is easily adjustable to accommodate electronic control systems, system hosts, and integrated lasers of varying heights. However, the following drawbacks remain:

[0004] (1) When using sensor lead soldering, it is difficult to reduce the force when clamping the sensor during soldering, which may damage the sensor if the clamp moves too fast.

[0005] (2) When using sensor lead welding, it is difficult to automatically push the sensor to the detection area for detection after the sensor welding is completed. To address this, an integrated automatic sensor lead welding and detection machine is proposed. Utility Model Content

[0006] The purpose of this invention is to address the current problem that it is difficult to reduce the force applied when clamping the sensor during welding, which may damage the sensor if the clamp moves too fast.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] The present invention is as follows: an integrated automatic welding and testing machine for sensor leads, comprising a workbench, a support frame fixedly connected to the bottom of the workbench, a welding device provided on the top of the workbench, and a clamping device provided on the top of the workbench.

[0009] The clamping device includes a motor, the side of which is fixedly connected to the side of the support frame. The output shaft of the motor is fixedly connected to a bidirectional threaded rod. A threaded sleeve is threadedly connected to the circumferential surface of the bidirectional threaded rod. A push plate is fixedly connected to the circumferential surface of the threaded sleeve. A slide groove is provided on the top of the worktable. A slider is slidably connected to the inner wall of the slide groove. A hollow block is fixedly connected to the side of the slider. A positioning pin slides through the inner wall of the hollow block.

[0010] As a preferred technical solution of this utility model, a flexible spring is fixedly connected to the inner wall of the hollow block, and the end of the flexible spring away from the hollow block is fixedly connected to the side of the positioning pin. A reset spring is fixedly connected to the inner wall of the slide groove, and the end of the reset spring away from the slide groove is fixedly connected to the side of the slider. The function of the flexible spring is to reset the positioning pin when it no longer clamps the item.

[0011] As a preferred technical solution of this utility model, a limiting rod is fixedly connected to the side of the support frame, and the circumferential surface of the limiting rod slides through the inner wall of the threaded sleeve. The function of the limiting rod is to restrict the movement trajectory of the threaded sleeve when it moves.

[0012] As a preferred technical solution of this utility model, the number of positioning pins and flexible springs is set to several, and they are arranged in a linear array along the vertical central axis of the hollow block. The number of threaded sleeves, push plates, slides, sliders, hollow blocks, positioning pins, flexible springs and reset springs are set to two, and they are symmetrical to each other along the vertical central axis of the worktable. The side of the slider is located on the displacement trajectory of the push plate. The purpose of setting multiple positioning pins and flexible springs is to better clamp the sensor.

[0013] As a preferred technical solution of this utility model, a pushing device is provided at the bottom of the workbench. The pushing device includes a first bevel gear, the inner wall of which is fixedly connected to the circumferential surface of a bidirectional threaded rod. A connecting plate is fixedly connected to the bottom of the workbench. A threaded rotating rod is rotatably connected to the front side of the connecting plate. A second bevel gear is fixedly connected to the front side of the threaded rotating rod. A threaded block is threadedly connected to the circumferential surface of the second bevel gear. A push rod is fixedly connected to the circumferential surface of the threaded block. A through groove is provided at the top of the workbench. The outer surface of the push rod is slidably connected to the inner wall of the through groove. The function of the second bevel gear is to drive the threaded rotating rod to rotate.

[0014] As a preferred technical solution of this utility model, a limiting shaft is fixedly connected to the front side of the connecting plate, and the circumferential surface of the limiting shaft slides through the inner wall of the threaded block. The function of the limiting shaft is to restrict the movement trajectory of the threaded block when it moves.

[0015] As a preferred technical solution of this utility model, the first bevel gear meshes with the second bevel gear, and the bottom of the push rod is located above the worktable. The purpose of the first bevel gear meshing with the second bevel gear is to drive the second bevel gear to rotate when the first bevel gear rotates.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. Through the clamping device, when the positioning pin moves and contacts the sensor, the hollow block continues to drive the positioning pin to clamp the sensor. Then the positioning pin will move into the hollow block. When the positioning pin moves to one end of the hollow block, the sensor can be clamped. Multiple positioning pins can be used to clamp sensors of different shapes. The reset spring can slow down the speed of the push plate pushing the slider, thereby preventing the hollow block from moving too fast and damaging the sensor.

[0018] 2. The set push device enables the bidirectional threaded rod to rotate in reverse, which in turn drives the first bevel gear to rotate in reverse. When the first bevel gear rotates in reverse, it drives the second bevel gear to rotate in reverse. When the second bevel gear rotates in reverse, it drives the threaded rod to rotate in reverse. When the threaded rod rotates in reverse, it drives the threaded block to move backward. When the threaded block moves backward, it drives the push rod to move backward. Thus, when the push rod moves backward, it can push the welded sensor to the detection area, thereby enabling the sensor to be detected. Attached Figure Description

[0037] Specifically, when using this sensor lead welding clamping device: First, when it is necessary to use this device to weld sensor leads, the clamping device 4 can be used to clamp the sensor during welding. By starting the motor 41, when the output shaft of the motor 41 rotates forward, it can drive the bidirectional threaded rod 42 to rotate forward. When the bidirectional threaded rod 42 rotates forward, it can drive the two threaded sleeves 43 to move towards the center. When the threaded sleeves 43 move towards the center, they can drive the push plate 44 to move towards the center. When the push plate 44 moves towards the center, it can push the slider 46 to move along the slide groove 45. When the slider 46 moves, it can drive... The hollow block 47 moves, which in turn drives the positioning pin 48 to move. When the positioning pin 48 moves and contacts the sensor, the hollow block 47 continues to drive the positioning pin 48 to clamp the sensor. The positioning pin 48 then moves into the hollow block 47. When the positioning pin 48 moves to one end of the hollow block 47, it can complete the clamping of the sensor. Multiple positioning pins 48 can be used to clamp sensors of different shapes. The reset spring 410 can slow down the speed at which the push plate 44 pushes the slider 46, thereby preventing the hollow block 47 from moving too fast and damaging the sensor.

[0038] The rotation of the bidirectional threaded rod 42 drives the pushing device 5. When the sensor welding is completed, the output shaft of the motor 41 reverses, driving the bidirectional threaded rod 42 to rotate in reverse. When the bidirectional threaded rod 42 rotates in reverse, it drives the first bevel gear 51 to rotate in reverse. When the first bevel gear 51 rotates in reverse, it drives the second bevel gear 54 to rotate in reverse. When the second bevel gear 54 rotates in reverse, it drives the threaded rotating rod 53 to rotate in reverse. When the threaded rotating rod 53 rotates in reverse, it drives the threaded block 55 to move backward. When the threaded block 55 moves backward, it drives the push rod 56 to move backward. Thus, when the push rod 56 moves backward, it can push the welded sensor to the detection area, thereby enabling the sensor to be detected.

[0039] All technical features in this embodiment can be freely combined according to actual needs.

[0040] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
