[0035] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0036] Example:

[0037] like Figure 1-Figure 4 As shown, a welding production line for door leaf gluing includes:

[0038] Workbench 1 and arranged on the workbench 1:

[0039] A roller group 2, wherein the roller group 2 is arranged on the workbench 1 through an ejection assembly, and the ejection assembly is used to drive the roller group 2 to rise or fall; after the roller group 2 rises, it supports the door leaf and drives the door leaf 16 forward;

[0040] Sensor 3, used for sensing door leaf 16;

[0041] A limiter, used to limit the door leaf 16 when the sensor 3 senses the door leaf 16;

[0042] A positioning member, used for positioning the door leaf 16;

[0043] A lateral clamping member for clamping the side of the door leaf 16;

[0044] The clamping assembly is used to clamp the door leaf 16 until it is close to the surface of the workbench 1.

[0045] The workbench 1 is a square table-shaped structure.

[0046] The workbench 1 is provided with a strip groove on the surface for the rollers of the roller group 2 to extend out;

[0047] The roller group 2 is arranged on the mounting frame 4, and the ejection assembly includes an ejection cylinder 5, the piston rod of the ejection cylinder 5 is connected to the bottom of the mounting frame 4, and the cylinder body of the ejection cylinder 5 is connected to the workbench 1 (fixed, and the fixing method can be but not limited to bolts).

[0048] The sensor 3 is disposed above the rear end of the workbench 1 through a bracket 6 . The sensor 3 may be, but is not limited to, a camera or an infrared sensor.

[0049] The limiting member comprises a limiting cylinder 7 , which is arranged at the rear end of the workbench 1 , and a piston end of the limiting cylinder 7 is arranged vertically upward.

[0050] The positioning member comprises a positioning cylinder 8, a piston end of the positioning cylinder 8 is provided with an ejector pin 9, and during positioning, the ejector pin 9 extends into the hinge positioning hole of the door leaf.

[0051] The lateral clamping member comprises a fixing block 10 and a lateral clamping cylinder 11 arranged on both sides of the workbench 1 , and the lateral clamping cylinder 11 is provided with a side clamping block 12 corresponding to the fixing block 10 .

[0052] The fixing block 10 and the side clamping block 12 are both square structures.

[0053] The clamping assembly includes a plurality of clamping cylinders 13, which are arranged on both sides and the tail end of the workbench 1. The clamping cylinders 13 at the tail end are arranged on the bracket 6.

[0054] A door leaf roller assembly line 14 is also provided at the head end of the workbench 1 , and a transition platform 15 is provided between the door leaf roller assembly line 14 and the workbench 1 .

[0055] Among them, 1. The clamping cylinder 13 located on one side of the workbench 1 is connected to the workbench 1 through a screw rod and a slider mechanism. When the screw rod handle is rotated, the clamping cylinder 13 on this side can be driven to move horizontally, thereby making the device suitable for clamping door leaves of different widths. 2. If the door production increases in the later stage, the two welders doing welding work at the workbench 1 can be replaced by welding robots, which can further reduce labor, and the front door leaf buckle plate and the rear automatic gluing assembly line can be connected to achieve the highest output efficiency.

[0056] Working principle: The worker (gusset plate) places the buckled door leaf 16 on the door leaf roller assembly line 14, and the roller on the door leaf roller assembly line 14 drives the door leaf to move toward the transition platform 15. After the door leaf 16 reaches the transition platform 15, it is transported to the workbench 1 through the transition platform 15.

[0057] When the door leaf 16 reaches the workbench 1, the ejection cylinder 5 drives the roller group 2 to protrude from the surface of the workbench 1. At this time, the door leaf is supported by the roller group 2; when the rollers of the roller group 2 rotate, the door leaf is driven forward.

[0058] When the door leaf 16 moves forward and the sensor 3 senses the door leaf 16 passing by, the limit cylinder 7 pushes out to limit the end surface of the door leaf to prevent the door leaf from moving excessively and limit the longitudinal direction of the door leaf. At the same time, the positioning cylinder 8 drives the ejector pin 9 on it to insert into the hinge positioning space corresponding to the door leaf to achieve accurate positioning of the door leaf.

[0059] Then the ejection cylinder 5 drives the workbench 1 to retract, so that the door leaf falls on the workbench 1 and is supported by the workbench 1. Then the lateral clamping cylinder 11 is actuated to move the door leaf toward the fixing block 10 through the side clamping block 12 until the other side of the door leaf contacts the fixing block 10. At this time, both sides of the door leaf are limited by the side clamping block 12 and the fixing block 10.

[0060] After the door leaf contacts the fixing block 10, the piston end of the clamping cylinder 13 moves downward to be clamped on the door leaf. After the clamping cylinder 13 is pressed down, the size of the plane and the workbench 1 is just equal to the thickness of the door leaf, ensuring that the thickness of each point of the door leaf is consistent. After the above actions are completed, two welders are arranged on both sides of the work platform to weld the door leaf, combining the initial welding of the original process with the reinforcement welding, and all the reinforcement welding is completed before gluing.

[0061] After welding is completed, the clamping cylinder 13, the lateral clamping cylinder 11, the limit cylinder 7, and the positioning cylinder 8 are retracted, the ejection cylinder 5 is ejected again, and the rollers of the roller group 2 roll to move the door leaf to the automatic gluing line (not shown in the figure) for gluing, and this set of processes is completed.

[0062] When welding the door leaf of the utility model, multiple pressing cylinders are used to press the door leaf before welding, so that the heights of various points of the door leaf are consistent, thereby improving the quality of the product; and because the welding is strengthened before gluing, the door leaf will not have the quality problem of misalignment.

[0063] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
