Description

Technical Field

[0001] This utility model relates to the field of machinery and equipment, and in particular to a lifting and leveling structure that uses spring tension to eliminate gaps. Background Technology

[0002] Existing electronic printing equipment requires lifting the circuit board to be processed on the processing table for subsequent processing steps. This is typically achieved using a motor or cylinder. The support table has multiple through holes (usually four), and limit rods are installed within these through holes, each with a circular stop at its top. After the motor or cylinder lifts the support table, the stop stops maintain its horizontal position. Because all four stop stops are on the same horizontal plane, the support table remains level after lifting.

[0003] However, with this design, if the limiting components are not on the same horizontal plane, the support platform will tilt after rising. This can lead to the electronic components not being installed properly during subsequent processing, resulting in a lower yield. Moreover, the machine needs to be leveled every time the machine position is changed, which greatly increases the inconvenience for users. Utility Model Content

The support platform body is connected to the base through the support rod. The drive motor is mounted on the support device base, and the output shaft of the drive motor is connected to the lower push platform. The drive motor can drive the lower push platform to move up and down, thereby driving the support platform body to move up and down.

[0007] The support rod includes a first support rod, a second support rod, a first spring, and a second spring. The bottom of the first support rod is fixedly connected to the base of the support device, and the top of the second support rod is fixedly connected to the support platform body. The top of the first support rod is provided with a first support rod connecting groove, the bottom of the second support rod is disposed in the first support rod connecting groove, and the second spring is sleeved on the outside of the second support rod.

[0012] The beneficial effects of this utility model's lifting and leveling structure that utilizes spring tension to eliminate gaps are as follows:

[0013] 1. By setting the first spring, it can cooperate with the support base to support the lower push platform. In addition, even if the support base is not completely leveled, as long as the difference is not too large, the first spring can eliminate the gap between the support base and the lower push platform, thereby playing an auxiliary role in leveling.

[0014] 2. By setting a second spring to support the support platform body, the gap between the support platform body and the lower support platform can be eliminated, thereby playing an auxiliary role in leveling. Attached Figure Description
