[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1: Please refer to Figure 1 - Figure 4 The figure shows a welding device for processing a computer case, comprising a conveyor belt 1 for conveying a main frame of the case and internal brackets of the case, a transport portion 2 provided at one end of the conveyor belt 1, through which the internal brackets of the case are transferred, and a mounting frame 3 provided at the outer end of the conveyor belt 1, a moving frame 4 provided inside the mounting frame 3, a clamping portion 5 for connecting the internal brackets of the case provided inside the moving frame 4, a welding member 6 provided outside the moving frame 4, a lifting member 7 for driving the moving frame 4 to rise and fall provided inside the mounting frame 3, and a limiting portion 8 provided at the bottom of the conveyor belt 1, which limits the outer side of the main frame of the case by abutting against the limiting portion 8;

[0028] In this solution, the designed conveyor belt 1 is used to transport the main frame and the internal bracket separately, and then the transport part 2 is used to transfer the internal bracket to the clamping part 5. After the internal bracket is clamped by the clamping part 5, the lifting part 7 is used to move the internal bracket down to the main frame. At the same time, the limit part 8 is triggered to position the main frame, so that the main frame and the internal bracket can be directly positioned when docking. Subsequently, the docking point is welded by the welding part 6, without the need for multi-step transfer and positioning, which makes the welding efficiency higher.

[0029] For further information, see Figure 1 - Figure 3 The transport portion 2 includes a transport frame 9 and a support frame 10. A transfer member 11 for driving the transport frame 9 is installed in the support frame 10. Two bidirectional threaded rods 12 are rotatably installed in the transport frame 9. The two ends of the two bidirectional threaded rods 12 are threadedly sleeved with clamping plates 13. Synchronous gears 14 are fixed to the outside of the two bidirectional threaded rods 12. Synchronous toothed belts 15 are engaged with the outside of the two synchronous gears 14. A drive motor 16 is fixed to the outside of the transport frame 9 through a motor frame. The output end of the drive motor 16 is fixed to the outer end of one of the bidirectional threaded rods 12.

[0030] Among them, the transfer part 11 includes a transfer screw 17 rotatably installed in the support frame 10 and a limit rod 18 fixed in the support frame 10. The transfer screw 17 is threadedly inserted into the transport frame 9, and the limit rod 18 is slidingly inserted into the transport frame 9. A transfer motor 19 is fixed to one side of the support frame 10 through a motor frame, and the output end of the transfer motor 19 is fixed to the outer end of the transfer screw 17 through a coupling.

[0031] In this scheme, the principle of the conveying part 2 driving the internal bracket for conveying is: first, the transfer motor 19 drives the transfer screw 17 to rotate, so that the conveying frame 9 moves to the end away from the limiting part 8, and then the conveyor belt 1 is used to move the internal bracket to between the two clamping plates 13, and then the drive motor 16 is used to drive the two clamping plates 13 to clamp the internal bracket, and then the transfer motor 19 drives the transfer screw 17 to reverse, so that the conveying frame 9 moves toward the moving frame 4, so that the internal bracket is against the inner wall of the moving frame 4, and then the clamping part 5 is used to clamp the internal bracket. At this time, the drive motor 16 reverses, so that the clamping plate 13 releases the internal bracket, and then the conveying frame 9 is moved to the initial position through the transfer part 11, completing a transfer operation on the internal bracket.

[0032] For further information, see Figure 4 、 Figure 7 as well as Figure 8 The clamping portion 5 includes a resisting bar 20 fixed to the inner wall of one side of the moving frame 4, a telescopic rod 21 is fixed to the inner wall of the other side of the moving frame 4, an offset block 22 is fixed to the outside of the telescopic rod 21, an arc-shaped plate 23 is provided on the offset block 22, an electric push rod 24 is fixed in the moving frame 4, and a moving block 25 is fixed to the output end of the electric push rod 24 through a connecting rod. An adjusting column 26 adapted to the arc-shaped plate 23 is fixed to the outside of the moving block 25, and a tension spring 27 fixed to the inner wall of the moving frame 4 and the outer wall of the offset block 22 is provided on the outer side of the telescopic rod 21;

[0033] Also, see Figure 4 and Figure 7The welding part 6 includes two moving screws 28 rotatably mounted on the outside of the moving frame 4. The outer ends of the two moving screws 28 are fixed with linkage gears 29. The outer sides of the two linkage gears 29 are meshed with linkage toothed belts 30. A moving motor 31 fixed to the outer end of one of the moving screws 28 is fixed on the moving frame 4 through a motor frame. The outer sides of the two moving screws 28 are threadedly sleeved with a moving seat 32 that fits with the outer wall of the moving frame 4. A welding gun 33 for welding the internal bracket of the chassis and the joint of the chassis main frame is installed in the moving seat 32.

[0034] The lifting member 7 includes a lifting screw rod 34 rotatably installed in the mounting frame 3, the lifting screw rod 34 is threadedly inserted into the moving frame 4, and a sliding rod 35 fixed to the mounting frame 3 is slidably inserted in the moving frame 4. A lifting motor 36 fixed to the outer end of the lifting screw rod 34 is fixed to the top of the mounting frame 3 through a motor frame.

[0035] In this solution, the principle of driving the internal bracket to move down to the main frame and welding it is as follows: first, after the clamping part 5 completes the clamping and positioning of the internal bracket, the lifting motor 36 in the lifting member 7 is rotated to move the movable frame 4 downward, so that the internal bracket and the main frame are in contact. After that, the moving motor 31 is driven to make the two movable screws 28 rotate synchronously, so that the two welding guns 33 are aligned with the joint of the internal bracket and the main frame and move, thereby completing the welding operation at the connection between the two.

[0036] It should also be noted that: when the movable frame 4 moves downward, the limit part 8 can be triggered synchronously, so that the internal bracket can complete the positioning of the main frame after docking with the main frame and before the welding operation, thereby reducing the time required for transfer, docking and positioning between the two and improving welding efficiency.

[0037] For further information, see Figure 3 - Figure 7 The limiting portion 8 includes a support column 37 fixed on the inner wall of one side of the conveyor belt 1 and a track plate 38 fixed on the inner wall of the other side of the conveyor belt 1. A moving opening 39 is opened on the track plate 38. A connecting rod 40 is slidably inserted into the moving opening 39. A limiting column 41 is fixed on the connecting rod 40. A connecting frame 42 is fixed to the outside of the limiting column 41. A linkage member 43 for driving the limiting column 41 to move is installed on the outside of the connecting frame 42.

[0038] Among them, the linkage part 43 includes an inclined block 44 fixed on the outside of the connecting frame 42, and the two ends of the movable frame 4 are respectively fixed with a support plate 45 and a limiting plate 46. The bottom of the support plate 45 and the limiting plate 46 are fixed with a contact plate adapted to the inclined block 44, and a tension spring 47 is installed in the movable opening 39 to drive the connecting rod 40 to retract.

[0039] In this solution, the main frame moves to between the stop column 37 and the limit column 41 as the conveyor belt 1 is transported. Subsequently, the moving frame 4 is driven downward by the lifting member 7, so that the stop strip 45 and the limit strip 46 on the moving frame 4 move downward synchronously. After the contact plate contacts the inclined surface of the inclined block 44, it drives the connecting frame 42 and the limit column 41 to move toward the main frame, cooperating with the stop column 37, thereby limiting the position of both sides of the main frame from the outside.

[0040] It should also be noted that: as the movable frame 4 moves downward, the abutment plate 45 and the limiting plate 46 fixed at its bottom also move downward synchronously, wherein the abutment plate 45 is a flat plate, which serves to abut one side of the main frame, and the cross-sectional shape of the side of the limiting plate 46 adjacent to the main frame is a trapezoid. When it moves downward, the inclined end of the limiting plate 46 will contact one side of the main frame, so that the front and rear of the main frame can be positioned, making the subsequent alignment between the main frame and the internal bracket more precise, and facilitating the subsequent assembly of other side panels.

[0041] In this solution, in order to avoid damage caused by contact with the outer side of the main frame, the stop column 37, the limit column 41, the stop strip plate 45 and the limit strip plate 46 are all made of rubber material.

[0042] Example 2: Please refer to Figure 4 - Figure 6 This embodiment further explains the first embodiment, and the difference lies in that a discharge structure is added below the conveyor belt 1 to enable the components welded to the main frame and the internal bracket to be discharged from the side of the conveyor belt 1.

[0043] Specifically, a discharge plate 48 is provided at the bottom of the conveyor belt 1 , and a plurality of rollers 49 are installed on the top of the discharge plate 48 . The plurality of rollers 49 are obliquely distributed in the gaps in the conveyor belt 1 .

[0044] In this solution, the unloading plate 48 is driven upward by the existing lifting mechanism, so that several rollers 49 are moved upward. After the main frame is lifted, the multiple rollers 49 distributed at an angle will assist it in discharging materials toward the side of the conveyor belt 1, making unloading after welding more convenient.

[0045] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0046] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
