[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0024] refer to Figure 1-5 The welding machine feeding assembly shown comprises a workbench 1 and a welding device 7, wherein the welding device 7 for welding two sets of plates 6 is installed on the workbench 1;

[0025] The electric welding equipment 7 can move in the Y-axis direction under the drive of the motor, and can move in the Z-axis direction under the action of the electric push rod. Under the control of the PLC control unit, the welding operation can be performed on two groups of plates 6.

[0026] The workbench 1 is provided with a loading rack 2 for storing the plate 6 through the mounting holes 11. The loading rack 2 is provided with two groups and is symmetrically arranged on both sides of the electric welding equipment 7. The mounting holes 11 are provided with multiple groups and are arranged in an array on the workbench 1. The position of the loading rack 2 in the mounting holes 11 can be adjusted according to the size of the plate 6 to be welded.

[0027] like Figure 2As shown, the workbench 1 is also provided with a loading cylinder 4 for pushing the plate 6 on the loading rack 2 to the welding equipment 7, and a pushing piece 5 is connected to the telescopic end of the loading cylinder 4, and the pushing piece 5 corresponds to the position of the plate 6 at the bottom of the loading rack 2; the loading rack 2 includes a front baffle frame and a column, and the front baffle frame, the column and the workbench 1 form a rectangular frame with a transparent top surface, and a discharge channel for the plate 6 to pass through is reserved between the front baffle frame and the workbench 1, and a loading trough 12 is opened on the workbench 1, the pushing piece 5 is located in the loading trough 12, and the top of the pushing piece 5 protrudes from the loading trough 12.

[0028] like Figure 5 As shown, the pushing member 5 can push and load the plate 6 under the push of the feeding cylinder 4. When it retracts under the drive of the feeding cylinder 4, it will not interfere with the plate 6 on the feeding rack 2, resulting in an inability to reset. The pushing member 5 includes a mounting block 51 and a pushing block 52. The mounting block 51 is connected to the telescopic end of the feeding cylinder 4, and a rotating groove 54 is provided on the mounting block 51 for the pushing block 52 to rotate 90 degrees. The mounting block 51 and the pushing block 52 are rotationally connected, and a torsion spring 53 is also provided to drive the pushing block 52 to reset.

[0029] like Figure 4 As shown, the workbench 1 is also rotatably connected with a flap 3 for unloading the welded plate. The flap 3 is driven by a unloading cylinder 8. Supported by the unloading cylinder 8, the flap 3 is flush with the workbench 1, supporting the plate 6 and ensuring that the electric welding equipment 7 can weld the plate 6 normally. After welding is completed, the unloading operation is performed on the welded plate under the action of the unloading cylinder 8, thereby realizing automated processing, reducing the labor intensity of the staff and improving work efficiency.

[0030] The workbench 1 is provided with a mounting groove, which is communicated with the loading trough 12. The flap 3 is located in the mounting groove, and the flap 3 is provided with a notch 32 corresponding to the position of the loading trough 12. One end of the flap 3 is rotatably connected to the workbench 1. A discharge cylinder 8 for controlling the flipping angle of the flap 3 is also provided under the workbench 1. The telescopic end of the discharge cylinder 8 corresponds to the position of the flap 3 and is connected with a slider. The flap 3 is provided with a slide groove 31 adapted to the slider. The slider and the slide groove 31 are used in conjunction with each other, so that the flap 3 can be stably reset under the drive of the discharge cylinder 8.

[0031] Working principle of the utility model: when in use, the equipment is connected to electricity and connected to the external PLC control unit, the plate 6 to be welded is placed in the loading rack 2, the loading cylinder 4 is controlled to work and extend, and the pushing piece 5 is driven to move toward the plate 6, the pushing block 52 of the pushing piece 5 contacts the lowermost plate 6 in the loading rack 2, and pushes the plate 6 to move toward the electric welding equipment 7, the pushing piece 5 slides in the loading slot 12 and the notch 32, and does not interfere with the workbench 1, when the two groups of plate 6 contact, the loading cylinder 4 stops extending, and controls the electric welding equipment 7 to perform welding operations on the two groups of plate 6;

[0032] After welding is completed, the loading cylinder 4 retracts, driving the pushing piece 5 to reset, and the pushing block 52 in the pushing piece 5 contacts the plate 6. Driven by the loading cylinder 4, the pushing block 52 continues to move away from the electric welding equipment 7. The pushing block 52 rotates around the hinge with the mounting block 51 under the obstruction of the plate 6, and the torsion spring 53 accumulates force. When the pushing block 52 is separated from the plate 6, it resets under the elastic force of the torsion spring 53, waiting for the next loading operation; the unloading cylinder 8 is controlled to contract, driving the slider to move downward, and at the same time, the flap 3 rotates around the hinge with the loading frame 2 under its own gravity and the pressure of the plate after welding. The plate is separated from the flap 3 under the action of its own gravity, completing the automatic unloading operation, realizing automated loading, welding and unloading operations, and controlling the unloading cylinder 8 to reset, driving the flap 3 to reset, preparing for the next welding operation.

[0033] The selection calculation needs to be determined based on the specification parameters of the electric welding equipment 7 and the specification range of the plate 6 to be welded. The selection calculation method adopts the existing technology, which is not improved in this application, so it will not be described in detail.

[0034] The electromechanical connection involved in the present utility model is a common means used by those skilled in the art, and technical inspiration can be obtained through a limited number of tests, which belongs to common knowledge.

[0035] Components not described in detail herein are prior art.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
