Description

Technical Field

[0001] The utility model relates to production equipment, in particular to production equipment for household appliances. Background Art

[0002] During production or testing, box-type products (such as washing machines) need to be shifted using a clamp installed on a translation and lifting system. The clamp clamps the box-type products. Driven by the lifting mechanism, the box-type products rise, and driven by the translation mechanism, the box-type products translate, and then descend to a predetermined position. The clamp generally includes a pair of jaws that can move away from or toward each other. Due to errors in the jaws or the product itself, it is difficult for the contact surface between the jaws and the product to achieve full contact. For example, there is an inclination angle between the clamping surface of the jaws and the side of the product. Even if the inclination angle is small, it is difficult for the clamping surface of the jaws to fully contact the side of the product (the contact surface with the jaws). This may result in: first, the side of the product is damaged by the jaws; second, the product falls during the shifting process. Utility Model Content

[0003] The technical problem solved by the utility model is that in the clamps in the prior art, a pair of jaws can only move away from or towards each other. Due to errors in the jaws or the product itself, it is difficult for the contact surface between the jaws and the product to achieve full contact, which may cause the side of the product to be damaged by the jaws, or the product to fall during the shifting process.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: a box translation mechanism includes a gantry, a translation seat movably engaged with the gantry, a lifting seat movably engaged with the translation seat, and a clamp engaged with the lifting seat. A translation drive unit is provided between the gantry and the translation seat, and a lifting drive unit is provided between the translation seat and the lifting seat. The clamp includes a pair of jaws, and a jaw drive unit that drives the pair of jaws away from or towards each other. The first jaw of the pair of jaws is installed with a fixed clamping plate, the second jaw is installed with a vertical plate, and a pair of vacuum suction cups are installed on the vertical plate, and the vacuum suction cups are arranged opposite to the fixed clamping plate.

[0005] When a pair of jaws grips a box-like product, the fixed plate of the first jaw rigidly contacts one side of the product, while the vacuum cup of the second jaw flexibly contacts the other side. The flexible material of the vacuum cup absorbs any parallelism errors between the side of the product and the second jaw. Under the combined grip of the jaws, one side of the box-like product is fully in contact with the fixed plate, while the other side is held by the vacuum cup. This ensures a stable grip of the box-like product, preventing damage to the product's sides or the product from falling during repositioning.

[0006] The fixed clamp is fixedly connected to the first pair of screws, which are in turn connected to the first clamping jaws. A first fastening nut is threaded onto the first pair of screws. The first clamping jaws have connecting holes through which the screws pass. The first fastening nuts on the screws are located on either side of the holes, clamping the first clamping jaws together to securely connect the screws. This design allows for an adjustable spacing between the fixed clamp and the first clamping jaws to accommodate products of varying sizes.

[0007] The vertical plate is fixedly connected to the second pair of screws, which are in turn connected to the second jaws. Second clamping nuts are threaded onto the second pair of screws. The second jaws have connecting holes through which the screws pass. Second clamping nuts on the screws, located on either side of the holes, clamp the second jaws, securing the screws and the second jaws. This design allows for adjustable spacing between the vertical plate and the second jaws to accommodate products of varying sizes.

[0008] A pair of vacuum cups is positioned above and below the second pair of screws. Specifically, the second pair of screws are positioned front and back, and the vacuum cups are positioned above and below, with the second pair of screws positioned midway between them. This design ensures balanced force on the vertical plate when clamping a product, allowing it to remain upright as much as possible. This allows the vacuum cups to maintain product retention and prevents the second pair of screws from bending.

[0009] The translation drive unit consists of a rack fixed to the gantry, a translation motor mounted on the translation base, and a gear mounted on the translation motor. The gear meshes with the rack. The translation motor rotates the gear, which rolls on the rack, driving the translation base to translate along the gantry.

[0010] A horizontal guide rail is provided on the gantry, and a sliding block matched with the horizontal guide rail is provided on the translation seat.

[0011] The lifting drive unit includes a lifting cylinder installed on the translation seat, a U-shaped piece connected to the lifting cylinder, and the U-shaped piece is connected to the lifting seat. Under the drive of the lifting cylinder, the lifting seat and the clamp thereon are lifted and lowered.

[0012] The two ends of the translation seat are provided with downward extension parts, on which vertical guide rails are provided, and the two ends of the lifting seat are provided with sliders that cooperate with the vertical guide rails. The vertical guide rails guide the lifting of the lifting seat.

[0013] The jaw drive unit consists of a dual-rotation screw pivotally connected to the lifting base and a motor that drives the screw. A screw nut is connected to the top of the pair of jaws, which mates with the dual-rotation screw. The motor rotates the dual-rotation screw. The forward thread of the screw drives one jaw toward the other, while the reverse thread of the screw drives the other jaw toward the first, thus bringing the jaws closer together.

[0014] The lifting base is equipped with a guide rail for the clamping jaws, and the clamping jaws are equipped with a slider that cooperates with the guide rail. The lifting base has a clearance hole, and the guide rail for the clamping jaws is mounted on the bottom surface of the lifting base. The dual-rotation screw is mounted on the top surface of the lifting base. A connector is connected between the top of the clamping jaw and the screw nut, and the connector passes through the clearance hole. BRIEF DESCRIPTION OF THE DRAWINGS
