Description

Clamping device

Technical field

The utility model relates to a clamping device.

Background technique

The housing or ring assembly of a mobile phone product is typically cleaned several times during processing. Such housings or ring assemblies need to be protected from scratches during the cleaning process, especially in cleaning processes where the component has been subjected to multiple surface treatments. The commonly used method in the industry is to clean the hanger after the hanger is attached to the product, and the hanger is fixed through the inner cavity of the process product, and then the hanger and the product are put into the cleaning basket for cleaning. This method is very effective in protecting the outer surface of the product without scratching and effectively ensuring the cleaning effect. However, in the prior art, the fixing of the product and the hanger is usually performed manually: the process is for the operator to take out the product from the carrier, and take out the hanger from the cleaning basket, and support the hanger in the inner cavity of the product, so that After the product is fixed, it is put into the carrier, and another operator puts the product of the hanger into the cleaning basket.

Detailed ways

As shown in FIG. 1 to FIG. 3, the clamping device 100 includes a feeding platform 10, a loading robot 20, and The hanger platform 30 is attached. The clamping device 100 is used to snap the hanger 40 into the corresponding workpiece 50. In a specific implementation, the workpiece 50 can be a housing component.

The feed platform 10 is used to position and position the workpiece 50 to be clamped. The loading robot 20 is used to transfer the workpiece 50 from the feeding platform 10 to the upper hanger platform 30.

The upper hanger platform 30 includes a hanger clamping station for placing and positioning the hanger 40 and a hanger receiving mechanism disposed at the hanger clamping station.

The hanger closing mechanism drives the hanger 40 at the hanger clamping station to deform, and the loading robot 20 transfers the workpiece 50 to the hanger 40, the hanger The take-up mechanism releases the hanger 40, and the hanger 40 recovers and clamps the workpiece 50. In a specific implementation, the hanger 40 can be made of a flexible material so that the hanger 40 can self-recover after the hanger 40 releases the hanger 40.

The hanger 40 can include an arched member 410, two connecting ends 420 disposed at opposite ends of the arched member 410, and a latching portion 430 disposed at the connecting end 420.

The hanger receiving mechanism is docked with the arched member 410. When the hanger receiving mechanism tensions the arched member 410, the connecting end 420 and the engaging portion 430 move toward the arched member 410, and the shape of the hanger 40 shrinks. The workpiece 50 can be sleeved and external to the hanger 40.

When the hanging device 410 releases the arched member 410, the connecting end 420 and the engaging portion 430 are reset, and the shape of the hanging device 40 returns to the normal state, that is, the hanging device 40 is unfolded, and the card is unfolded. The joint 430 is snapped into a predetermined card slot on the workpiece 50 to clamp the workpiece 50.

In a specific implementation, the hanger 50 may further include a slide bar. Both ends of the arched member 410 are provided with through holes that match the slide bars. In this way, when the hanger closing mechanism tensions or releases the arched member 410, both ends of the arched member 410 can slide along the slide bar through the through hole. The slide bar can guide the deformation of the arched member 410.

The rack closing mechanism may include a pressure claw 330, a Z-direction moving module 320, and an X-direction moving module 310.

The jaws 330 are used to tension or release the arched member 410. The X-direction mobile module 310 is coupled to the Z-direction mobile module 320 and drives the pressure finger 330 together with the Z-direction mobile module 320. In a specific implementation, the X-direction moving module 310 can drive the jaws 330 to translate to approach or away from the arched member 410.

The Z-direction moving module 320 can drive the pressure claw 330 to move up and down. For example, the Z-direction moving module 320 can first drive the pressure claw 330 to rise above the arched member 410, and then drive the pressure. The pawl 330 is depressed to cause the pawl 330 to tension the arched member 410. The Z-direction moving module 320 again drives the claws 330 to rise to release the arched member 410.

The Z-direction mobile module 320 can be mounted on the X-direction mobile module 310. The pressure claw 330 is mounted on the Z-direction moving module 320.

In a preferred embodiment, the upper rack platform 30 includes a first station 301 and a second station 302. The first station 301 and the second station 302 are respectively provided with a hanger receiving mechanism. The first station 301 and the second station 302 can be put into use alternately. For example, when the first station 301 performs the operation of the upper hanger 40, the operator can perform the operation of picking and placing the hanger 40 at the second station 302, thereby improving efficiency.

The upper hanger platform 30 further includes a second bracket 303 and a slide rail mounted on the second bracket 303. The first station 301 and the second station 302 are respectively slidably connected to the slide rail through a sliding portion to facilitate switching the working position.

In another preferred embodiment, the first station 301 and the second station 302 are respectively provided with a plurality of hanger receiving mechanisms.

The feeding platform 10 includes a first bracket 110 and a carrier 120 placed and positioned on the first bracket 110. The workpiece 50 to be clamped is housed in the carrier 120.

A plurality of storage positions for accommodating the workpiece 50 are provided in the carrier 120. The loading mechanism includes a loading robot 20 and a plurality of reclaiming mechanisms 210 installed in the front of the loading robot 20 (only one of the reclaiming mechanisms 210 is shown). The plurality of reclaiming mechanisms 210 are docked with the plurality of storage positions to simultaneously take out the plurality of workpieces 50 at the plurality of storage locations.

The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the present invention. The scope of protection of utility models.
