Description

Switch box interval adjusting device

Technical Field

The utility model relates to the technical field of auxiliary switch box stacking equipment, in particular to a switch box spacing adjusting device.

Background

At present, the electric circuit in the building mostly adopts a concealed installation mode, and a bottom box, namely a switch box, is pre-buried in the wall when the switch or the socket is installed.

The prior art discloses automatic assembly equipment for a bottom box of a switch box with an iron sheet, which comprises an assembly stand, a box body feeding mechanism, an iron sheet feeding mechanism, a pressing mechanism, a detection mechanism, a discharging mechanism and a control mechanism, wherein a continuously rotating turntable is arranged on the assembly stand, and the box body feeding mechanism, the iron sheet feeding mechanism, the pressing mechanism, the detection mechanism and the discharging mechanism are all arranged around the turntable in sequence along the rotating direction of the turntable and are electrically connected with the control mechanism; the iron sheet feeding mechanism comprises a vibrating disc, a separating mechanism and a carrying mechanism, wherein the vibrating disc is used for adjusting the direction of the iron sheet, the separating mechanism is used for enabling the iron sheet to be placed independently, the carrying mechanism is used for transferring the iron sheet to the rotary disc, the head end of the separating mechanism is connected with the tail end of the vibrating disc, and the carrying mechanism is arranged at the tail end of the separating mechanism.

In actual production, after the switch box assembled by the assembly equipment is conveyed to the tail end of the conveyor belt, the switch box on the conveying line is required to be transferred into a packaging box for stacking. If the mechanical clamping jaws are used for directly grabbing the switch boxes on the conveying line into the packaging boxes one by one for stacking, the mechanical clamping jaws always interfere with the adjacent switch boxes in the process of placing the switch boxes, and finally a certain distance is always reserved between the two adjacent switch boxes in the packaging boxes. Therefore, the prior art firstly utilizes the manipulator to grab the switch boxes on the conveying line one by one onto the sorting table top to form a plurality of rows, then manually adjusts two adjacent rows of switch boxes to be in a mutually adjacent state, and finally utilizes another manipulator to grab the switch boxes with adjusted spacing into the packaging box together for stacking, thereby improving the space utilization rate of the packaging box.

However, manual adjustment of the spacing between the switch boxes requires a certain amount of labor and also presents a certain safety risk for the worker working between the two manipulators.

the switch box interval adjusting device comprises a supporting seat, a driving part, a fixed plate and a sliding plate, wherein the driving part is arranged on the supporting seat, the fixed plate and the sliding plate are positioned on the same horizontal plane, and the axis in the length direction of the sliding plate is parallel to the axis in the length direction of the fixed plate; the fixed plate is fixedly connected with the supporting seat, and a plurality of first clamping structures for being clamped with the switch box are distributed on the fixed plate at intervals along the length direction of the fixed plate; the sliding plate is in sliding connection with the supporting seat along the connecting line direction of the sliding plate and the fixed plate, and a plurality of second clamping structures for clamping the switch box are distributed on the sliding plate at intervals along the length direction of the sliding plate; the driving part is used for driving the sliding plate to slide.

In the technical scheme, in the initial state, a certain distance is kept between the fixed plate and the sliding plate as well as between the fixed plate and two adjacent sliding plates, after a row of switch boxes are respectively placed on the fixed plate and the sliding plates, the switch boxes on the fixed plate are clamped with the first clamping structure so as to be stabilized on the fixed plate, and the switch boxes on the sliding plate are clamped with the second clamping structure so as to be stabilized on the sliding plate; then the driving part drives the sliding plate to slide towards the direction of the fixed plate until the sliding plate is abutted against the fixed plate, so that two adjacent rows of switch boxes are adjacent to each other; finally, the switch boxes on the fixed plate and the sliding plate can be used as a layer by using another manipulator on the station and simultaneously grabbed and transported to the next station for stacking. The sliding plate is driven to slide through the driving part, so that the distance between two adjacent switch boxes is adjusted, manual intervention is not needed, and labor is saved, and safety is improved.

Preferably, a plurality of sliding plates are provided, and the axes of two adjacent sliding plates in the length direction are parallel to each other. The number of the switch boxes on the same layer can be increased by arranging the sliding plates, so that the transfer efficiency of the switch boxes is improved.

In the sliding process of the sliding plates, the included angle between the first connecting rod and the second connecting rod on the same cross assembly changes along with the sliding of the sliding plates, and because the cross assemblies are connected in sequence, each cross assembly is mutually restrained, when one sliding plate slides, the other sliding plates also synchronously slide, and thus the driving part only needs to drive one sliding plate to slide so as to drive the other sliding plates to slide, and the setting number of the driving part can be reduced.

The driving mode of the driving component can be one of synchronous belt driving, air cylinder driving, hydraulic cylinder driving, screw rod driving, gear rack driving and electric push rod driving.

Before the sliding plate is abutted with the fixed plate, a piston rod of the hydraulic buffer extends out to a certain length in the direction of the fixed block, when the cylinder drives the sliding plate to slide to be close to the fixed plate, the hydraulic buffer slides along with the sliding plate and the piston rod of the hydraulic buffer is abutted with the fixed plate, and the piston rod of the hydraulic buffer gradually and slowly retracts after receiving the impact force of the fixed plate, so that the sliding plate slowly slides to be abutted with the fixed plate.

Preferably, the support seat is provided with a first proximity sensor, and the first proximity sensor is used for sensing one sliding plate adjacent to the fixed plate when the sliding plate adjacent to the fixed plate is abutted to the fixed plate. When the first proximity sensor senses the sliding plate, the sliding plate is indicated to slide to be abutted with the fixed plate, namely the distance between the switch boxes is adjusted.

Preferably, the support base is further provided with a second proximity sensor, and the second proximity sensor is used for sensing one sliding plate far away from the fixed plate when the sliding plate far away from the fixed plate slides to an initial state.

Preferably, the two sides of the supporting seat are provided with a first guide rail and a second guide rail which are parallel to each other, and two ends of the sliding plate are respectively connected with the first guide rail and the second guide rail in a sliding way. The two ends of the sliding plate slide along the first guide rail and the second guide rail respectively, so that the parallelism of the sliding plate and the fixed plate can be ensured, and the sliding of the sliding plate can be improved to be more stable.

Preferably, the first clamping structure comprises a first clamping groove for placing the switch box or a first protrusion for clamping with the inner cavity of the switch box; the second clamping structure comprises a second clamping groove for placing the switch box or a second protrusion for being clamped with the inner cavity of the switch box.
