Description

Technical Field

[0001] The present invention belongs to the technical field of microswitch processing, and particularly relates to a fully automatic microswitch welding machine. Background Art

[0002] A microswitch is a quick-acting mechanism with a small contact interval, a contact mechanism that performs switch actions with a specified stroke and a specified force, covered with a housing, and has a drive rod on the outside. Because the contact spacing of its switch is relatively small, it is named a microswitch. Microswitches are used for automatic control and safety protection in equipment that needs to frequently switch circuits, and are widely used in electronic equipment, instruments, mines, power systems, household appliances, electrical equipment, and military fields such as aerospace, aviation, ships, missiles, and tanks.

[0003] A microswitch has 3 points (i.e., reed pieces), one is a normally open point, one is a closed point, and there is also a common point in the middle. Sometimes the exposed end of the reed piece is shorter than the reed pieces of the normally open point and the closed point. Three leads need to be welded on the three reed pieces. The lead of the common point is welded on one side, and the leads of the normally open point and the closed point are welded on the other side. Therefore, it needs to be turned over during welding. Currently, it is mostly manually welded. Due to the small spacing of the reed pieces and limited welding space, the manual welding efficiency is low, and it is difficult to ensure the welding quality, easy to make mistakes, and the rejection rate is high.

[0004] Therefore, a fully automatic microswitch welding machine is needed to solve the problems of poor wiring welding quality and low welding efficiency of microswitches in the prior art. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0048] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions.

[0049] Please refer to Figures 1-15, the present invention provides a fully automatic welding machine for microswitches, which includes a frame 1. The upper end of the frame 1 is a working platform, and a divider 2 is installed in the middle of the working platform; the divider 2 is a precision 8-station divider, and each station is respectively named the first station 21 to the eighth station 28, and a switch fixing clamp 3 is installed on each station; on one side of the frame 1, there is a feeding mechanism 4 (i.e., beside the first station 21), which is used for feeding the microswitches with leads to be welded; on the working platform, outside the central axis corresponding to the first station 21, there is a flipping feeding mechanism 5, which is used to send the microswitches sent by the feeding mechanism 4 into the switch fixing clamp 3 of the first station 21; on the working platform, outside the central axis corresponding to the third station 23, there is a long wire welding mechanism 6, which is used to weld leads on the reed of the common point of the microswitch; on the working platform, outside the central axis corresponding to the fourth station 24, there is a turning-over mechanism 7, which is used to turn over the microswitch to facilitate welding leads on the normally open point and the closed point in the next step; on the working platform, outside the central axis corresponding to the fifth station 25, there is a short wire welding mechanism 8, which is used to weld leads on the two reeds of the normally open point and the closed point of the microswitch; on the working platform, outside the central axis corresponding to the sixth station 26, there is a discharging mechanism 9, and the microswitches with welded leads are sent out through the discharging mechanism 9. The second station 22 and the seventh station 27 are detection stations, and detection devices (not shown in the figure) are provided to judge whether there are microswitches in the switch fixing clamp 3.

[0050] Further, as Figure 3 shown, the switch fixing clamp 3 includes a fixed seat 31, an upper clamping block 32, a lower clamping block 33, a push rod 34 and a push rod cylinder 35; the fixed seat 31 is fixedly installed on each station of the divider 2, and the surface facing the outside of the divider 2 is the installation surface 311 of the upper clamping block 32 and the lower clamping block 33.

The push rod 34 and the push rod cylinder 35 are arranged below the rear end of the lower clamping block 33, and the lever rotation of the lower clamping block 33 is controlled by combining an internal return spring (not shown in the figure). After the push rod cylinder 35 acts, the push rod 34 extends, pushing the rear end of the lower clamping block 33 upwards, then the clamping head opens, and at this time, the microswitch to be welded can be placed; when the push rod cylinder 35 returns, the return spring presses down the rear end of the lower clamping block 33, then the clamping head maintains the clamping state.

[0051] Further, as Figure 4As shown in the figure, the loading mechanism 4 includes a switch tray 41 and a switch pushing mechanism 42. The switch tray 41 is installed on the loading moving mechanism 43 and is provided with a plurality of material grooves 411. The material grooves 411 are T-shaped two-layer grooves, wider at the top and narrower at the bottom. The reeds of the micro switches are inserted downward into the lower layer grooves and placed in rows. The switch pushing mechanism 42 is arranged above the switch tray 41 and includes a push head power mechanism 421, a push head lifting cylinder 422 and a push head 423. The push head lifting cylinder 421 is fixedly installed on the push head power mechanism 421, and the piston rod is connected downward to the push head 423. On one side of the switch tray 41 close to the frame 1, there is a connection groove 44 for docking with the flipping feeding mechanism 5. Driven by the push head power mechanism 421, the push head 423 starts from the side away from the frame 1 and pushes a row of switches on the switch tray 41 into the flipping feeding mechanism 5 through the connection groove 44. After each row is pushed, the loading moving mechanism 43 drives the switch tray 41 to move to the next row.

[0053] The stop feeding mechanism 53 includes a stop feeding cylinder 531, a stop feeding block 532 and a stop feeding base 533. The stop feeding base 533 is fixedly installed on the frame 1, is docked with the other end of the linear vibrating feeding track 51, and is correspondingly provided with a switch conveying groove 534 on the upper end face. Two switches can be placed in the switch conveying groove 534 (i.e., the switch placement positions at the incoming material end and the outgoing material end, not shown in the figure). The stop feeding cylinder 531 is arranged on one side of the stop feeding base 533, the piston rod is connected to the stop feeding block 532, and the stop feeding block 532 is correspondingly installed on the switch placement position at the incoming material end (i.e., the docking end with the linear vibrating feeding track 51). When the stop feeding cylinder 531 acts, the stop feeding block 532 is pushed out to form a clamping state on the switch at this switch placement position, preventing the subsequent switch from being pushed forward continuously. A stop feeding block limiting groove 535 is also provided on the stop feeding base 533 to prevent the stop feeding block 532 from running off during operation and ensure the accuracy of clamping. In the initial state, the switch placement position at the outgoing material end is located in the middle of the first clamping jaw 523, and the stop feeding base 533 is provided with a concave surface corresponding to the switch placement position at the outgoing material end to facilitate the first clamping jaw 523 to clamp the micro switch.

[0054] The flipping mechanism 54 includes a positioning cylinder 541, a positioning block 542, a positioning base 543, a second clamping cylinder 544, a first rotating cylinder 545 and a first lifting cylinder 546, and a second clamping jaw 547 is provided on the second clamping cylinder 544. The positioning cylinder 541 is fixedly installed on the frame 1, one end of the positioning block 542 is fixedly installed on the piston rod of the positioning cylinder 541 opposite to it, and the other end is slidably installed on the positioning base 543. A plurality of switch clamping plates 548 are installed above the positioning base 543 to form a switch placement position and at the same time form an upper limit for the positioning block 542. After the micro switch is placed, the positioning block 542 faces the reed of the micro switch. The second clamping cylinder 544 is installed on the first rotating cylinder 545, and the first rotating cylinder 545 is installed on the first lifting cylinder 546, and a second clamping jaw 547 is provided on the second clamping cylinder 544.

[0055] The first clamping jaw 523 clamps the micro switch on the switch placement position at the outgoing material end of the stop feeding base 533 under the drive of the first clamping cylinder 522, and then moves to the positioning base 543 under the drive of the material transfer cylinder 521. The positioning cylinder 541 drives the positioning block 542 to press the reed to fix the micro switch, and the first clamping jaw 523 can then loosen and return. The first lifting cylinder 546 is fixedly installed on the frame 1, and the piston rod faces upward. During the clamping operation, the piston rod of the first lifting cylinder 546 retracts, driving the first rotating cylinder 545 and the second clamping cylinder 544 to descend. The second clamping jaw 547 clamps the front and rear two rectangular surfaces of the micro switch under the drive of the second clamping cylinder 544. After clamping, it is driven to rise by the first lifting cylinder 546, and the first rotating cylinder 545 drives the second clamping cylinder 544 and the second clamping jaw 547 to rotate 90 degrees until the micro switch is in a horizontal state.

[0056] The feeding mechanism 55 includes a third jaw 551, a third clamping cylinder 552, a feeding track 553, and a feeding cylinder 554. The feeding track 553 is fixedly installed on a feeding bracket 555, and the feeding bracket 555 is fixedly installed on the machine frame 1. The feeding track 553 is arranged in parallel above the extension line of the central axis from the first station 21 to the center of the divider 2. A feeding slider 556 is slidably arranged on the feeding track 553. The feeding cylinder 554 is a two-way cylinder and is installed on the feeding bracket 555, and the piston rod is connected to the feeding slider 556. The third clamping cylinder 552 is fixedly installed directly above the extension line of the central axis of the first station 21 on the side of the feeding cylinder 554, and the third jaw 551 is directly opposite the middle of the upper clamping block 32 and the lower clamping block 33 of the switch fixing clamp 3 at the first station 21. Driven by the third clamping cylinder 552, the third jaw 551 clamps both sides of the microswitch on the second jaw 547, and the second jaw 547 can then be loosened and flipped back to its original position. Then, the ejector cylinder 35 of the switch fixing clamp 3 at the first station 21 moves upward, driving the lower clamping block 33 to act and open.
