Description

Technical Field

[0001] The invention relates to the technical field of automatic switch automated production, in particular to automatic assembly equipment for an automatic conversion switch shaft mechanism. Background Art

[0002] Transfer switch is a common low-voltage electrical appliance, which is often used in important power distribution occasions such as airports, hospitals, and data centers. It is used to switch between two power sources to ensure that when the normal power supply fails during the power supply process, it can quickly switch to the backup power supply to ensure normal power supply to the load end.

[0003] With the rapid development of economy and society and technological progress, the performance and reliability of modern power supply and distribution systems need to meet the needs of increasingly diverse load types. As a distribution device used in the power supply end of critical occasions, the transfer switch has complex and diverse load conditions at the lower end. When switching the power supply, the main circuit will inevitably produce abnormal conditions such as impact current, abnormal voltage, phase difference, etc.

[0004] The shaft mechanism is a key component of the automatic transfer switch, and its structure usually includes an upper cover, a base, a moving contact piece, a spring piece, a support plate and rivets.

[0005] Due to the complex structure, many small parts are assembled, and the moving contact and spring are extremely thin. The spring is also elastic and difficult to be compressed and installed, resulting in low manual assembly efficiency and the existence of missing parts and missing parts. Because rivets need to be inserted through multiple parts holes at the same time, manual assembly holes are not easy to align, and the auxiliary device needs to use a large force to complete the alignment, resulting in high labor intensity and easy fatigue.

[0006] Therefore, it is necessary to design a complete set of automated equipment to complete the overall assembly of the shaft assembly to replace manual labor, improve production efficiency and reduce the defective rate.

[0007] However, the difficulty in designing automated assembly equipment, in addition to the problems encountered manually, is that the moving contact piece and the spring piece need to be assembled in the inner cavity groove of the upper cover body and the base in a mirror-symmetrical manner according to the design, which brings about the problem of processing in the feeding link. Since conventional vibration plates can only output materials in a single posture, they cannot perform intelligent mirror-symmetrical processing and other technical problems, all of which need to be overcome one by one in the present invention.

[0011] The upper cover installation device comprises a third feeding mechanism, an upper cover assembly clamping jaw, and a clamping jaw servo driving mechanism. The clamping jaw servo driving mechanism of the upper cover installation device drives the upper cover assembly clamping jaw to clamp the upper cover from the outlet of the third feeding mechanism, so that the upper cover splicing interface is opposite to the cavity opening of the upper cover assembly cavity, and the upper cover is installed in the upper cover assembly cavity. The upper cover is provided with an inner cavity groove engaged with the moving contact piece and the spring piece. The upper cover is opposite to the upper cover assembly cavity, and the moving contact piece and the spring piece are clamped into the inner cavity groove and fixed;

[0013] The base installation device comprises a fourth feeding mechanism, a base assembly clamping claw, and a clamping claw servo driving mechanism. The clamping claw servo driving mechanism of the base installation device drives the base assembly clamping claw to clamp the base from the outlet of the fourth feeding mechanism and install it in the base assembly cavity.

[0014] The cover closing device comprises a cover closing clamp and a clamp servo drive mechanism, wherein the clamp servo drive mechanism drives the cover closing clamp to clamp the upper cover body with the moving contact piece and the spring piece from the upper cover assembly cavity, and assemble the upper cover body with the base in the base assembly cavity to form a rotating shaft assembly;

[0015] The second tooling device comprises a combined cavity adapted to the profile of the rotating shaft assembly, and the combined cavity is provided with an installation slide groove communicating with the support plate groove at a position corresponding to the support plate groove of the rotating shaft assembly;

[0016] The support plate installation device comprises a fifth feeding mechanism, a suction cup mechanism, and a clamping claw servo driving mechanism. The clamping claw servo driving mechanism of the support plate installation device drives the suction cup mechanism to suck the support plate from the outlet of the fifth feeding mechanism and install it in the installation slide groove.

[0017] The rivet installation device includes a sixth feeding mechanism, a rivet guide mechanism, a push plate mechanism and a riveting mechanism.

The rivet guide mechanism is connected to the outlet of the sixth feeding mechanism and extends to the first rivet hole to guide the rivet into the first rivet hole and the second rivet hole. The riveting mechanism rivets the rivets in the first rivet hole and the second rivet hole.

[0018] By adopting the above technical solution, through the designed direction adjustment mechanism, through the cooperation of the turntable and the moving contact piece direction adjustment clamp, the two moving contact pieces clamped in the same direction are rotated at intervals and adjusted to a mirror-symmetrical posture, and then grasped by the moving contact piece assembly clamp to the first workpiece loading tool.

[0019] The gripper servo mechanism includes a base, a horizontal track, a horizontal slide, a horizontal cylinder, a vertical slide, a vertical track, and a vertical cylinder. Each gripper is designed according to the contour of the part to be gripped and is fixedly connected to the vertical slide. The vertical track is set on the horizontal slide. The base is set on the horizontal track and is pushed back and forth by the cylinder to achieve horizontal and vertical movement to coordinate the movement of each gripper.

[0020] During the grasping process of the spring sheet assembly claw, because the spring sheet has an arc, if it is transported in a vertical posture, it will fit each other and it is difficult to separate it individually. Therefore, a separation flap is set to first output it in a horizontal posture and then flip it to a vertical posture.

[0021] And because the installation position spacing of the two mirror-image spring sheets in the first tooling is too large, clamping the two together will increase the size of the clamping jaws. Therefore, a rotary table can be set on the vertical slide to drive the spring sheet assembly clamping jaws to rotate and clamp the two spring sheets for rotational installation.

[0022] Through the designed first tooling, utilizing the designed upper cover assembly cavity and base assembly cavity structure, step-by-step assembly is achieved. First, the moving contact piece, spring piece and other components inside the shell are pre-installed in the upper assembly cavity, and the moving contact piece is limited and fixed by using two first mounting grooves and spacing limit blocks that are mirrored and matched with the contour of the moving contact piece between the left limit block and the right limit block.

[0023] The spring sheet is fixed by using the spring-piece limiting columns on both sides in conjunction with the installed moving contact sheet, thus completing the pre-assembly of the internal parts.

[0024] Then, the inverted upper cover is connected to the upper cover assembly cavity, so that the pre-installed moving contact piece and spring piece are directly inserted into the upper cover. In this way, the most difficult internal parts and upper cover assembly are completed by using the precise positioning of the first tool. Then, the upper cover is grabbed and assembled with the fixed base in the base assembly cavity to complete the assembly of the main part of the shaft assembly.

[0025] Then, the second tooling structure is used to push the support plate from the support plate slot of the shaft assembly through the support plate installation device and the rivet installation device, so that the first rivet hole and the second rivet hole overlap, and then the rivet is introduced for riveting. The overall assembly is completed.

[0030] By adopting the above technical solution, during the riveting process, there is a deviation in the pressing stroke of the organic riveting mechanism. If the second tooling tool is fixed, the riveting stroke will be blocked and the riveting will not be in place. Therefore, the second tooling tool is set to a structure that can slide vertically with the riveting to adapt to the position caused by the deviation.
