Description

Technical Field

[0001] The present invention relates to the field of bottom plate assembly, and particularly relates to an automatic positioning device for assembling rollers and a pallet. Background Art

[0002] The bottom plate with rollers is a commonly used pallet in logistics transportation, which is convenient for moving items. Due to the presence of rollers at the bottom, it is more labor-saving when moving. However, the installation of the wheels is crucial. If the installed wheels are deviated, resulting in uneven support, excessive squeezing force will be applied to one direction when using the pallet, which is likely to cause damage to the pallet and make the pallet unable to be used normally. When installing the wheels, it is not easy to accurately position the installation position of the rollers, resulting in deviation of the installation position and unbalanced installation. Therefore, the inventor invented an automatic positioning device for assembling rollers and a pallet to solve the installation problem of the rollers on the bottom plate. Summary of the Invention

[0003] The purpose of the present invention is to solve the deficiencies of the prior art and provide an automatic positioning device for assembling rollers and a pallet.

[0004] The present invention is realized through the following technical solutions:

[0005] An automatic positioning device for assembling rollers and a pallet, including a bottom plate, on the bottom surface of which bases are symmetrically installed. On the upper surface of the left side of the bottom plate, a pallet is installed. A hinge is installed between the pallet and the bottom plate. In the middle of the surface of the pallet, a support disk is installed. In the middle of the support disk, a rotating shaft is installed. A first turntable is sleeved on the surface of the rotating shaft. A crank is installed at the front end of the surface of the rotating shaft. Guide rods are symmetrically installed on the outer periphery of the surface of the support disk. The outer ends of the guide rods are fixedly connected with positioning strips. A connecting block is sleeved inside the guide rods. A slider is sleeved on the top of the surface of the connecting block. A suction cup is sleeved on the bottom of the surface of the connecting block. A first spiral spring is connected between the slider and the positioning strip. A traction rope is connected between the first turntable and the slider. In front of the pallet, a support rod fixedly connected with the bottom plate is installed. At the top of the support rod, a machine base is fixedly installed. On the upper side of the machine base, a motor is fixedly installed. A second turntable is installed in the middle of the motor. A pulling rope is wound around the second turntable. The lower end of the pulling rope is fixedly connected with a clamping block. On the lower surface of the right side of the bottom plate, a connecting plate is fixedly installed. At the right end of the connecting plate, a guiding frame is fixedly installed. A second spiral spring is sleeved on the surface of the guiding frame. The lower end of the second spiral spring is connected with a sliding ring. On the left side surface of the sliding ring, a connecting rod is fixedly connected. At the left end of the connecting rod, a support frame is fixedly installed. An imprinting layer is sleeved inside the support frame.

[0006] Preferably, the clamping block is of a U-shaped structure.

[0007] Preferably, both the slider and the suction cup are slidably matched with the guide rods.

[0008] Preferably, the sucker is made of a magnet.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] Through the control of the motor, the present invention facilitates the flipping of the support plate. At the same time, by rotating the first turntable, the towing rope is pulled to adjust and control the position of the sucker, so as to facilitate the use of the sucker to adsorb the roller and adjust the position of the roller, making the rollers evenly distributed on the bottom surface of the support plate, realizing the preliminary positioning of the rollers. Through the setting of the support frame and the cooperation of the imprint layer, it is convenient to use the imprint layer to position the rollers. Through the dual positioning of the sucker and the imprint layer, the installation of the rollers is more stable, preventing the installation position of the rollers from deviating, and at the same time making the installation of the rollers more balanced. By pulling the towing rope with the first turntable, the present invention facilitates the adjustment of the position of the sucker, adjusts the position of the roller with the sucker, realizes the positioning of the roller, and makes the installation of the roller more stable.
