Abstract
Description
Technical Field
[0001] The utility model relates to the field of chip processing, in particular to a wire feeding mechanism used for sensor processing. Background Art
[0002] In order to convert the collected physical, chemical or biological signals into electrical signals, such as converting temperature, pressure, gas concentration and other signals into voltage, current or resistance signals, so that these physical, chemical or biological signals can be read and processed by electronic devices such as microcontrollers; at the same time, in order to filter, amplify, transmit and store the processed signals, most sensors are equipped with chips.
[0003] In order to install the chip, a welding process is usually used to connect the chip to a mounting base such as a circuit board or a base. In the existing welding process, the chip and the mounting base are first fixed on a fixture or other fixed tooling, and then the fixed tooling carrying the chip is placed at the welding processing site, and then the soldering wire is used to connect the chip and the soldering points on the mounting base, and then the welding gun is used to weld the soldering points to connect the chip and the mounting base. Due to the differences in the sizes of different chips, and in order to improve production efficiency and quality, automatic welding equipment is often used to replace manual operations. In the above application scenarios, the wire feeding mechanism is required to adjust the position of the wire outlet according to the position of the chip. Utility Model Content
[0004] The purpose of the utility model is to solve the above problems and provide a wire feeding mechanism for sensor processing, which can adjust the position of the wire outlet.
[0005] To achieve the above purpose, the technical solution adopted in this application is a wire feeding mechanism for sensor processing, including a bracket, a wire feeding seat is arranged at the upper end of the bracket, a wire winding frame and a wire outlet nozzle are arranged on the wire feeding seat, and a conveying mechanism is arranged between the wire winding frame and the wire outlet nozzle; the lower end of the bracket is arranged on a sliding seat, the sliding seat is slidably matched with a transverse guide rail, and the length direction of the transverse guide rail is different from the conveying direction of the conveying mechanism; the wire feeding seat moves vertically under the action of a vertical driving mechanism. The position of the wire outlet is adjusted by lifting and lowering the wire feeding seat and moving the bracket.
[0006] Furthermore, the wire winding rack is rotatably arranged on the wire feeding seat to facilitate the transportation of the welding wire.
[0007] Furthermore, the conveying mechanism includes a conveying roller group, which includes two conveying rollers disposed on both sides of the welding wire. At least one conveying roller is transmission-connected to the wire feeding motor to ensure the conveying of the welding wire and facilitate the control system to detect the length of the welding wire.
[0008] Furthermore, along the direction of movement of the welding wire, the conveying roller groups should be arranged at intervals, and the welding wire is clamped by multiple groups of conveying roller groups, so that the welding wire is kept in a taut state at the conveying mechanism to improve the conveying accuracy of the welding wire.
[0009] Furthermore, a transmission roller is arranged between the wire winding rack and the conveying mechanism, so that the welding wire is kept in a tensioned state during the conveying process, thereby improving the conveying accuracy of the welding wire.
[0010] The beneficial effects of the present application are as follows: the bracket moves in the horizontal direction with the sliding seat, and the bracket moves in a different way from the conveying direction of the conveying mechanism, thereby adjusting the position of the wire outlet nozzle to ensure that the welding wire can move to the welding point. At the same time, since the welding wire is mostly alloy wire with a relatively hard hardness, and in order to protect the chip, circuit board, etc., it is required that the welding wire cannot rub against the chip, etc. during the movement, so the wire feed seat can be raised and lowered under the action of the vertical drive mechanism, so that during the wire feeding process, the wire feed nozzle rises together with the wire feed seat, so that the welding wire is higher than the welding point. When the length of the welding wire coming out of the wire feed nozzle reaches the specified requirement, the wire feed seat is lowered again, so that the welding wire contacts the welding point, ensuring that the chip, etc. will not be damaged.

[0016] Embodiment 1, as Figure 1-3As shown, the structure of this embodiment is: a wire feeding mechanism for sensor processing, including a bracket 1, a wire feeding seat 2 is arranged on the upper end of the bracket 1, a wire winding frame 3 and a wire outlet nozzle 4 are arranged on the wire feeding seat 2, the wire winding frame 3 and the wire outlet nozzle 4 are arranged on the same side, and the wire winding frame 3 is the center of the circle, the center of the wire winding frame 3 is installed on the wire feeding seat 2 through a rotating shaft, and a conveying mechanism is arranged between the wire winding frame 3 and the wire outlet nozzle 4. The lower end of the bracket 1 is arranged on a sliding seat 5, and the sliding seat 5 is slidably matched with a transverse guide rail 6. The length direction of the transverse guide rail 6 is different from the conveying direction of the conveying mechanism. In this embodiment, the length direction of the transverse guide rail 6 is perpendicular to the conveying direction of the conveying mechanism on the vertical projection plane. The lower end of the bracket 1 is connected to a transverse driving mechanism 11, and the transverse driving mechanism 11 is fixedly installed on a workbench or the like in the same direction as the transverse guide rail 6; the wire feeding seat 2 moves vertically under the action of the vertical driving mechanism 7, and the vertical driving mechanism 7 is fixedly installed on the bracket 1; the transverse driving mechanism 11 and the vertical driving mechanism 7 can adopt linear driving mechanisms such as linear modules, cylinders, and electric push rods.
[0017] The conveying mechanism includes a conveying roller group, which should be arranged at intervals along the direction of movement of the welding wire. The conveying roller group includes two conveying rollers 8 disposed on both sides of the welding wire, and at least one conveying roller 8 is connected to the wire feeding motor 9 through a belt, a chain, a gear, etc. In this embodiment, the output shaft of the wire feeding motor 9 is connected to the rotating shaft of the conveying roller 8 through a belt, and the belt is wound around the rotating shafts of multiple conveying rollers 8. A transmission roller 10 is arranged between the wire winding frame 3 and the conveying mechanism, and the transmission roller 10 is not at the same height as the conveying mechanism.
[0018] In the specific engineering process, the staff installs the wire winding frame 3 with the welding wire wound on the wire feeding seat 2, and then passes one end of the welding wire around the transmission roller 10, then passes through the conveying mechanism, and then extends into the wire outlet nozzle 4, and the welding wire is clamped by the conveying roller group. Then adjust the position of the bracket 1 according to the position of the welding point, so that the wire outlet of the wire outlet nozzle 4 is aligned with the welding point. After the adjustment of the bracket 1 is completed and the chip mode is good, the wire feeding seat 2 rises, so that the outlet of the wire outlet nozzle 4 is higher than the welding point, and the wire feeding motor 9 drives the conveying roller 8 to rotate, so that the welding wire moves out of the wire outlet of the wire outlet nozzle 4. Since the speed of the wire feeding motor 9 is known, the wire length can be controlled by controlling the start time of the wire feeding motor 9. After the welding wire is moved, the wire feeding seat 2 descends, so that the welding wire contacts the welding point.
