Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

In addition, all directional indications in this application (such as up, down, left, right, front, back, bottom...) are only used to explain the relative position relationship, movement, etc. between the components in a certain specific posture (as shown in the drawings).

[0031] Example

[0032] In the prior art, the unloading station of the frame riveted longitudinal beam mainly relies on manual lifting and unloading, which cannot achieve accurate unloading and affects the production rhythm. This embodiment provides an automatic unloading device for the frame longitudinal beam buffer, and designs a special longitudinal beam unloading device, which can improve production efficiency and reduce manual labor intensity.

[0033] The automatic unloading device for the frame longitudinal beam buffer provided in this embodiment is as follows: Figure 1 As shown, it includes a main frame 1, a stop pin 2, a material discharge mechanism 3, a manual material discharge mechanism 4, and a non-powered conveying track 5. Among them,

[0034] The main frame 1 is used to support the structural foundation of the entire equipment and ensure the fixation and stability of each component.

[0035] Stop pin 2 Figure 2 As shown, it is used to control the position of the longitudinal beam. Through the telescopic action controlled by PLC, it automatically blocks or releases the longitudinal beam to ensure that the longitudinal beam enters the unloading area as planned. The automatic stop pin improves the control accuracy and reduces manual operation, thus improving the automation level of the equipment.

[0036] Discharging mechanism 3 Figure 3 As shown, it is used to accurately release the longitudinal beam from the waiting area to the unloading area. Furthermore, the unloading mechanism 3 is a connecting rod flipping mechanism, which moves the longitudinal beam from the buffer area to the waiting area, and then completes the accurate unloading of the longitudinal beam through the flipping action. In addition, the unloading mechanism 3 also includes a butterfly spring buffer device, specifically, a butterfly spring is designed at the impact load part for buffering to solve the problem of the mechanism being damaged by the impact load.

[0037] The manual discharging mechanism 4 is used to place the longitudinal beam, and the worker places the longitudinal beam here and prepares to enter the equipment. The design of the manual discharging mechanism is convenient for the operator to accurately place the longitudinal beam into the unloading system. Furthermore, a safety confirmation button is equipped to ensure the safety of the worker's operation.

[0038] As for the specific design of the non-powered conveyor track 5, a slope and a non-powered roller structure are used to make the longitudinal beam slide smoothly by its own gravity, reduce energy consumption and simplify the equipment structure. The non-powered conveyor track 5 is divided into three areas: a longitudinal beam buffer area, a material unloading waiting area, and an automatic unloading area. The longitudinal beam buffer area is for storing longitudinal beams waiting for unloading, the material unloading waiting area is for waiting to enter the unloading area, and the automatic unloading area is for completing the longitudinal beam unloading operation.

[0039] The stop pin 2 is located between the longitudinal beam buffer area and the material unloading waiting area. The material unloading is automatically performed by the extension and retraction of the automatic stop pin 2. The material unloading waiting area and the automatic unloading area are unloaded by the automatic flipping mechanism.

[0040] Furthermore, the extension and retraction of the stop pin 2 and the flipping of the material discharge mechanism 3 are controlled by a PLC (Programmable Logic Controller) and are linked with the main line.

[0041] The operating principle of the device provided in this embodiment is as follows:

[0042] During the production process, the longitudinal beam is placed on the manual discharge mechanism 4. At this time, the operator presses the safety confirmation button, the manual discharge mechanism 4 descends, and the frame longitudinal beam slides into the non-powered conveying track 5 by gravity. At this time, the stop pin 2 is in an extended state, blocking the longitudinal beam in the longitudinal beam buffer area 5. When the line body is ready for unloading, the discharge mechanism 3 is in a raised state, the stop pin 2 retracts, and after the longitudinal beam slides to the unloading area, the stop pin 2 extends, the discharge mechanism 3 is knocked down, and the longitudinal beam in the unloading waiting area slides down to the line body, realizing automatic and precise unloading.

[0043] The above describes the specific embodiments of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical concept of the present invention.
