Description

TECHNICAL FIELD

[0001] The utility model relates to automatic production line technical field, concretely relates to a carrier disc jacking device. BACKGROUND

[0002] In the production line of precision machinery or electronic products, the products to be processed are placed in the dedicated carrier disc in a fixed posture, and the carrier disc is transported to the downstream work station through the conveying track such as the conveying belt. In order to ensure the precision of product processing, assembly or measurement, the carrier disc needs to be positioned after reaching the work station, and the carrier disc is generally jacked up by the jacking device to separate from the conveying track, so that each product can be processed in a fixed position and the processing process will not be disturbed by the conveying track.

[0003] The prior art patent with the name of "Heavy load jacking rotary positioning device" (CN221680022U) discloses a technical solution that the jacking assembly is mainly composed of a piston rod, a fixed plate, a jacking cylinder, a mounting plate and a guide sleeve. The cooperation between the guide sleeve and the mounting plate during the jacking process of the jacking cylinder ensures the vertical upward movement of the tray assembly, thereby ensuring the levelness of the tray surface. However, the above-mentioned scheme lacks a buffer structure when the carrier disc is jacked up to the highest position, resulting in a large vibration when the piston rod jacks up the carrier disc to the highest position, and the carrier disc has the risk of deviation and generates a large noise. UTILITY MODEL CONTENT

[0004] The utility model aims at providing a carrier disc jacking device which can ensure the stability of the carrier disc when the piston rod jacks up the carrier disc to the highest position.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the technical scheme of a carrier disc jacking device. The mounting base plate constituting the rack is fixedly connected with a cylinder, and the piston rod of the cylinder is vertically arranged upwards. The top end of the piston rod is connected with a support plate arranged horizontally on the plate surface. A horizontal support surface for supporting the carrier disc is arranged on the support plate. The horizontal support surface is located above the support plate. A limiting pin for limiting the rotation of the carrier disc in the horizontal support surface is arranged on the support plate. A damping unit is arranged on the rack to form a vertical direction buffer with the support plate.

[0006] The utility model mainly jacks up the support plate by the piston rod of the cylinder to make the support surface in a horizontal posture. The limiting pin for limiting the rotation of the carrier disc in the horizontal support surface is arranged on the support plate to ensure the posture of the carrier disc. The damping unit is arranged to reduce the vibration generated when the piston rod drives the support plate to move to the highest position, thereby ensuring the stability of the carrier disc supported on the support plate.

[0009] Referring to Figures 1-2 The carrier plate lifting device shown, the mounting base plate 1 constituting the rack is fixedly connected with a cylinder 10 and the piston rod 11 of the cylinder 10 is arranged vertically upward, the top end of the piston rod 11 is connected with a support plate 20 arranged horizontally, the support plate 20 is provided with a horizontal supporting surface which supports the disc surface of the carrier plate A horizontally, the horizontal supporting surface is located above the support plate 20, the support plate 20 is provided with a limiting pin 22 which limits the rotation of the carrier plate A in the horizontal supporting surface, and the rack is provided with a damping unit which constitutes a vertical direction buffering cooperation with the support plate 20.

[0010] In the above scheme, the carrier plate A is placed on two parallel conveying belts and is conveyed to the downstream processing station along with the conveying belts, and the mounting base plate 1 on the processing station is located between the two conveying belts and below the carrier plate A. After the detection mechanism on the conveying line detects that the carrier plate A reaches the predetermined position, the piston rod 11 is lifted upward to drive the support plate 20 at the top end of the piston rod 11 to vertically displace upward, and the horizontal supporting surface on the support plate 20 lifts the carrier plate A to make it separate from the conveying belt, and the subsequent processing procedure is started. The limiting pin 22 not only limits the rotation of the carrier plate A in the horizontal supporting surface, but also plays a positioning role for the carrier plate A, limiting the translation of the carrier plate A in the horizontal supporting surface. The damping unit constitutes a buffering cooperation between the vertical direction and the support plate 20, which can reduce the vibration generated when the piston rod 11 drives the support plate 20 to displace to the highest position, thereby ensuring the stability of the carrier plate A supported on the support plate 20.

[0011] Specifically, at least three columns 21 are provided on the support plate 20 and the top surfaces of the columns 21 form a horizontal supporting surface, and the column cores of the columns 21 form a triangular shape. The limiting pins 22 are arranged vertically on the plate surface of the support plate 20 and two limiting pins 22 are provided, and the rod cores of the two limiting pins 22 intersect with the triangular area enclosed by the column cores of the columns 21. In the above scheme, the columns 21 with triangular column core connection lines leave a certain distance between the horizontal supporting surface supporting the carrier plate A and the support plate 20, which can be adjusted by adjusting the length of the columns 21 to facilitate application in different stations. In addition to limiting the position of the carrier plate A, the two limiting pins 22 also support the carrier plate A.

[0012] In order to precisely control the lifting height of the lifting device, the bottom surface of the support plate 20 extends downward with a guide column 30, the guide column 30 and the mounting base plate 1 constitute vertical guide cooperation for limiting the rotation of the guide column 30, the other end of the guide column 30 is fixedly connected to the auxiliary plate 40, the auxiliary plate 40 is separately arranged on the upper and lower sides of the mounting base plate 1 with the support plate 20. The bottom surface of the cylinder body of the air cylinder 10 extends vertically downward with a guide rod 50, the guide rod 50 and the auxiliary plate 40 constitute vertical direction guide cooperation. The rod end of the guide rod 50 is provided with a limit block 51, when the support plate 20 is in the high position of lifting, the limit block 51 abuts against the bottom surface of the auxiliary plate 40. In the above scheme, the guide rod 50 can limit the vertical displacement of the support plate 20 as the guide column 30, the spacing between the top surface of the limit block 51 and the bottom surface of the auxiliary plate 40 is the maximum lifting distance of the piston rod 11 of the air cylinder 10.

[0013] Preferably, the number of guide columns 30 is two, and the line connecting the guide columns 30 and the core of the piston rod 11 is a triangle. The vertical guide cooperation between the two guide columns 30 and the mounting base plate 1 can limit the rotation of the guide column 30, and the two guide columns 30 and the core of the piston rod 11 are not collinear, which can ensure the levelness of the supporting surface of the auxiliary plate 20.

[0014] More specifically, a buffer 41 constituting a damping unit is arranged between the cylinder body of the air cylinder 10 and the auxiliary plate 40. The damping unit is arranged below the cylinder body of the air cylinder 10, which can reduce the space occupation above the air cylinder 10, and facilitate the spatial arrangement of other parts.
