Description

Technical Field

[0001] The present application relates to production equipment for electrical box covers, and in particular to an automatic pressing and nesting device for electrical box covers. Background Art

[0002] The description in this section only provides background information related to the present disclosure and does not constitute prior art. In the related art, the components of the battery pack are roughly divided into a lower box, battery cells, internal electrical connectors, and an electric box cover, etc. The battery pack cover and the lower box are generally assembled by locking. If the box cover is directly locked, it will cause the torque attenuation of the locking bolt after vibration. Therefore, the locking hole generally needs to be installed with a metal nest before being assembled with the lower box.

[0003] The nesting installation method in the related art is mostly manual placement and nesting. Although there is positioning, there are problems such as inaccurate nesting position and product damage caused by cylinder downward pressure. In addition, the nesting installation is manual placement and nesting. When the cylinder is pressed down, if the operator's hand is not removed from the downward pressure area in time, it is easy to cause the person's fingers to be crushed, which poses a safety hazard. In addition, the production efficiency of manual assembly is low. Summary of the invention

[0004] In view of this, the present application provides an automatic nesting pressing device for an electrical box cover, which can improve the nesting installation efficiency and increase safety.

[0005] In order to achieve the above objectives, this application is implemented through the following technical solutions:

[0007] The positioning mechanism includes a column, a movable pin and a compression spring. The column is fixedly arranged on the frame and has a cavity in its body. The movable pin is vertically movably connected in the cavity. The compression spring is pressed tightly between the movable pin and the cavity to provide a reverse reset force. The upper end of the column has a supporting surface supported on the bottom of the box cover. The upper end of the movable pin is provided with a step for nesting. The upper end of the movable pin can pass through the lock hole of the box cover upwards to position the lock hole.

The manipulator has a simple structure, mainly consisting of two slide cylinders and a manual clamp, and has a low manufacturing cost.

[0011] In some embodiments, the pressing device includes a pressing cylinder fixedly mounted on the first bracket, and the pressing cylinder is located directly above the positioning mechanism.

[0036] The locking hole 71 of the box cover 7 is aligned with the movable pin 22 by mechanical equipment or manually to achieve the positioning of the corresponding locking hole 71. The vibration plate continuously conveys the nest 6 during the vibration process and moves it into the U-shaped mouth 5221 of the blocking member 522 through the conveying guide rail 51. When it is necessary to rivet the nest 6, the upper cylinder 523 rises to lift up a nest 6, and the pneumatic clamping claws 34 of the manipulator 3 descend to grab the nest 6 from the left and right sides, and the second slide cylinder 33 rises, and then the first slide cylinder 32 extends forward to move the nest 6 to the top of the movable pin 22, and the second slide cylinder 33 descends to place the nest 6 on the step 221 of the movable pin 22, and the pneumatic clamping claws 34 are released. Then the various components of the manipulator 3 are reset, and the pressing device 4 descends to press the nest 6 into the locking hole 71 of the box cover 7 to complete the installation of one hole position, and then adjust another hole position to dock with the movable pin 22, and then repeat the above working process to rivet the nest 6 of each hole position.
