[0051] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0052] This application provides an automatic material placement mechanism and a welding furnace, which solves the problem that existing weldable parts need to be placed manually one by one, and realizes automatic feeding of weldable parts.

[0053] The technical solution in this application is to solve the above-mentioned technical problems, and the general idea is as follows:

[0054] Before welding, the parts to be welded need to be placed on the conveyor belt at the furnace opening so that they can enter the furnace for welding.

[0055] However, the existing parts to be welded need to be placed manually one by one, which is inefficient.

[0056] Research has found that, for example Figures 1-10 As shown, by setting up an automatic material placement mechanism, multiple parts to be welded can be pushed simultaneously, which solves the problem that manual material placement is required when welding existing parts, realizes automatic feeding of parts to be welded, and improves overall work efficiency.

[0057] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0058] Example:

[0059] like Figures 1-5 As shown, an automatic material handling mechanism includes a support body 1, a material transfer platform 2, and a material dropping structure 3;

[0060] The material dropping structure 3 is installed on the material transfer table 2. A hollow cavity 30 is provided on the material dropping structure 3. Multiple parts 31 to be welded that are adapted to the hollow cavity 30 are vertically stacked inside the hollow cavity 30.

[0061] The transfer table 2 includes two symmetrically arranged L-shaped plates, with the notched side of the two L-shaped plates being the side that is close to each other, and the two plates are fixed by a connector;

[0062] A support groove 20 is formed between the notches of the two L-shaped plates, and the support groove 20 is used to support the placement of multiple parts 31 to be welded.

[0063] A pushing groove 21 is formed between the two L-shaped plates, and the pushing groove 21 is located below the support groove 20 and communicates with the support groove 20;

[0064] The transfer table 2 is installed on the support body 1 and fixed to the support body 1. The support body 1 is also equipped with a positioning block 10, a slider 11 and a reciprocating structure. The slider 11 is slidably connected to the positioning block 10 through a sliding groove and slides back and forth on the positioning block 10 through the reciprocating structure.

[0065] The slider 11 is equipped with a plurality of swing rods 16, each of which is rotatably connected to a support 15 fixedly connected to the slider 11 via a rotating rod. The slider 11 is equipped with a plurality of micro motors corresponding to the swing rods 16 one by one, each of which is used to drive the corresponding rotating rod and control the swing rod 16 to rotate.

[0066] The distance between the bottom of the material dropping structure 3 and the support groove 20 is less than the thickness of the two pieces 31 to be welded stacked together. The swing rod 16 pushes one piece 31 to be welded located below the material dropping structure 3 at a time.

[0067] During the material placement process, each swing rod 16 pushes the corresponding part 31 to be welded in sequence, and multiple parts 31 to be welded located on the transfer platform 2 are simultaneously pushed to the next placement position.

[0068] By setting up an automatic material placement mechanism, multiple parts 31 to be welded are pushed simultaneously using the automatic material placement mechanism, which solves the problem that manual material placement is required when welding the parts 31 to be welded. This achieves automatic feeding of the parts 31 to be welded and improves the overall work efficiency.

[0069] like Figures 1-3 As shown, the reciprocating mechanism includes a first connecting rod 12, a second connecting rod 13, and a third connecting rod 14. The first connecting rod 12 is rotatably connected to the support body 1 via a first rotating shaft. The second connecting rod 13 is rotatably connected to the end of the first connecting rod 12 away from the first rotating shaft via a second rotating shaft. The third connecting rod 14 is rotatably connected to the end of the second connecting rod 13 away from the second rotating shaft via a third rotating shaft. The side of the third connecting rod 14 away from the third rotating shaft passes through the positioning block 10 and is fixedly connected to the slider 11, and is slidably connected to the positioning block 10.

[0070] The rotating shaft is driven by a drive motor, which is mounted on the support body 1 and fixedly connected to the support body 1.

[0071] By setting the reciprocating mechanism in the form of connecting rod 12, connecting rod 23 and connecting rod 34, driving connecting rod 12 controls connecting rod 23 and connecting rod 34 to drive the slider 11 to slide back and forth on the positioning block 10, realizing the gradual pushing of each part 31 to be welded on the transfer table 2, realizing the subsequent automatic feeding operation during the welding process. The whole structure is simple and compact, which is convenient for the automatic material placement mechanism to be deployed during use.

[0072] The reciprocating structure provides driving force to the rotating shaft 1 through the motor. Since the connecting rod 12 is rotatably connected to the support body 1 through the rotating shaft 1, the drive motor controls the rotation of the connecting rod 12, which in turn controls the swing of the connecting rod 2 13, which is rotatably connected to the connecting rod 12. During the swing of the connecting rod 2 13, the connecting rod 2 13 drives the connecting rod 3 14 to move back and forth, which in turn controls the slider 11, which is fixedly connected to the connecting rod 3 14, to move back and forth along the groove in the positioning block 10, thus realizing the reciprocating process of the slider 11.

[0073] like Figure 5 As shown, the support groove 20 is adapted to multiple parts 31 to be welded;

[0074] During the material placement process, multiple parts 31 to be welded located on the transfer platform 2 are in contact with the wall of the support groove 20.

[0075] By setting the support groove 20 to fit the workpiece 31 to be welded, the stability of the workpiece 31 to be welded is improved when it is pushed along the support groove 20, thereby improving the overall regularity of the material placement.

[0076] like Figure 5 As shown, two symmetrically arranged support blocks 22 are installed on the material transfer table 2. Each support block 22 is fixedly connected to the corresponding L-shaped material plate, and each support block 22 is provided with a screw hole.

[0077] The side of the blanking structure 3 is provided with screw hole 2, which corresponds to screw hole 1.

[0078] During installation, the material drop structure 3 is fixed by bolts passing through the corresponding screw holes one and two.

[0079] The installation of the material dropping structure 3 and the material transfer platform 2 is achieved by using the support block 22, and the installation is carried out by using bolts through screw holes one and two. The whole installation method is simple and easy to operate.

[0080] like Figures 5-10 As shown, the material feeding structure 3 has multiple slots 301, and all of the slots 301 are connected to the hollow cavity 30.

[0081] Two insert plates 32 are installed inside the material dropping structure 3, and each insert plate 32 is inserted into the material dropping structure 3 through a corresponding slot 301.

[0082] Two overlapping blocks 23 are symmetrically arranged on the transfer table 2, and each overlapping block 23 is detachably connected to the corresponding L-shaped material plate;

[0083] The two overlapping blocks 23 are used to adjust the width of the support groove 20 and the pushing groove 21;

[0084] After insertion, the bottom of both insert plates 32 is flush with the bottom of the material dropping structure 3 and in contact with the overlapping block 23.

[0085] Specifically, each of the overlapping blocks 23 is fixedly connected to the corresponding L-shaped material plate by bolts.

[0086] By setting up the overlap block 23, the width of the support groove 20 and the push groove 21 can be adjusted using the overlap block 23 to realize the placement of the workpieces 31 of different lengths to be welded.

[0087] It should be noted that, during use, the insert plate 32 is inserted into the corresponding slot 301 according to the length of the workpiece 31 to be welded, and the corresponding overlapping block 23 is selected to adjust the support groove 20 so that the support groove 20 is adapted to the workpiece 31 of the corresponding length, so that the material placement mechanism can be used for automatic material placement of workpieces 31 of different lengths.

[0088] like Figure 1 As shown, a welding furnace includes an automatic material feeding mechanism and a furnace body 4, wherein the automatic material feeding mechanism is fixedly connected to the furnace body 4 via a connecting plate;

[0089] A material conveying platform 40 is provided on the side of the furnace body 4 near the material feeding mechanism. A conveyor belt 411 is installed on the material conveying platform 40. The conveyor belt 411 enters the furnace opening of the furnace body 4 through the rotating roller 41.

[0090] The horizontal plane of the conveyor belt 411 is flush with the bottom of the workpiece 31 to be welded placed on the transfer table 2;

[0091] During material placement, the workpiece 31 to be welded, which is near one end of the conveyor belt 411, is transferred to the horizontal surface of the conveyor belt 411 for conveying under the push of the swing arm 16.

[0092] By setting the automatic feeding mechanism on the furnace body 4 of the welding furnace, the automatic feeding of the workpieces 31 to be welded in the welding furnace can be realized.

[0093] Specifically, in practical applications, two baffles can be set on the material conveying platform 40. The two baffles are located on both sides of the conveyor belt 411 to limit the transfer of the workpiece 31 to be welded on the automatic feeding mechanism and to protect the transfer of the workpiece 31 to be welded on the material transfer platform 2.

[0094] During operation, according to the length of the workpiece 31 to be welded, the insert plate 32 is inserted into the corresponding slot 301. The length of the stacking space of the workpiece 31 to be welded in the blanking structure 3 is adjusted by the two insert plates 32 so as to accommodate the stacking of workpieces 31 of different lengths in the blanking structure 3.

[0095] At the same time, according to the length of the part to be welded 31, the matching lap block 23 is installed on the corresponding L-shaped material plate, and the width of the support groove 20 between the two L-shaped material plates is adjusted so that the width of the support groove 20 can be matched with the length of the part to be welded 31.

[0096] After the adjustment is completed, multiple parts to be welded 31 are vertically stacked in the unloading structure 3. Under the action of gravity, multiple parts to be welded 31 are automatically unloaded along the cavity wall of the hollow cavity 30. In actual application, the distance between the bottom of the unloading structure 3 and the bottom of the support groove 20 is less than the thickness of two parts to be welded 31. Therefore, only one part to be welded 31 can be completely exposed in the support groove 20 at a time. Specifically, when setting it up, the distance between the bottom of the unloading structure 3 and the bottom of the support groove 20 is the thickness of one and a half parts to be welded 31, which makes it easy for one part to be welded 31 to be unloaded at a time.

[0097] It should be noted that when setting the support block 22, multiple screw holes are opened on each support block 22 along the vertical direction of the blanking structure 3, so as to adjust the distance between the bottom of the blanking structure 3 and the bottom of the support groove 20, which facilitates the blanking operation of the workpiece 31 to be welded with different thicknesses.

[0098] After the automatic feeding of material feeding structure 3, such as Figure 4 As shown, in the initial state, multiple swing arms 16 are respectively located at their corresponding placement positions and in contact with the workpiece 31 to be welded. Among them, the swing arm 16 near the unloading structure 3 is vertical and in contact with the side of the workpiece 31 to be welded below the unloading structure 3. Then, the reciprocating structure drives the slider 11 to slide towards the welding furnace from the positioning block 10, and simultaneously controls the swing arms 16 to rotate towards one side of the furnace body 4, pushing the workpiece 31 to be welded at the placement position. The workpiece 31 to be welded is gradually pushed to the placement position that is gradually closer to the furnace body 4. When the slider 11 moves away from the positioning block 10 and the swing arm 16 is between two placement positions, the multiple swing arms 16 rotate synchronously to Figure 4 In state two, the swing arm 16 in state two moves to the initial swing position under the action of the reciprocating structure. At this time, the weldment 313 in the initial state moves to the position of weldment 2 312, the weldment 2 312 in the initial state moves to the position of weldment 1 311, and the weldment 1 311 in the initial state moves to the conveyor belt 411 on the furnace body 4 and enters the furnace body 4 through the furnace opening under the action of the conveyor belt 411 for welding.

[0099] Subsequently, as the reciprocating structure returns to its original position, multiple swing arms 16 are controlled to reset to their initial state. The slider 11 slides back and forth along the positioning block 10 to approach or move away from the furnace body 4. Combined with the rotation of the swing arms 16, the sequential feeding operation of the workpiece 31 to be welded is realized.

[0100] It should be noted that the operation of the conveyor belt 411, the reciprocating structure, and the rotation of the multiple swing arms 16 are all controlled by a CNC system, and the multiple structures do not interfere with each other during operation.

[0101] When the swing arm 16 pushes the workpiece 31 closest to the material placement position of the furnace body 4 onto the conveyor belt 411, the swing arm 16 rotates to complete the pushing process of the workpiece 31, and the swing arm 16 never contacts the conveyor belt 411.

[0102] Welding part 1 311, welding part 2 312 and welding part 3 313 are all the same welding part 31.

[0103] In summary, compared with existing technologies, it has the following beneficial effects:

[0104] 1. By setting up an automatic material placement mechanism, multiple parts 31 to be welded are pushed simultaneously by the automatic material placement mechanism, which solves the problem that manual material placement is required when welding the parts 31 to be welded. This realizes the automatic feeding operation of the parts 31 to be welded and improves the overall work efficiency.

[0105] 2. By setting the support groove 20 to fit the workpiece 31 to be welded, the stability of the workpiece 31 to be welded is improved when it is pushed along the support groove 20, thereby improving the overall regularity of the material placement.

[0106] 3. By setting up the overlap block 23, the width of the support groove 20 and the push groove 21 can be adjusted by the overlap block 23 to realize the placement of the workpieces 31 of different lengths to be welded.
