[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technology in the embodiments of the present invention, a welding device for forming shelf layers. 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 creative work are within the scope of protection of the present invention. Example 1

[0021] like Figure 1 — Figure 3 As shown, a welding device for forming shelf layer plates comprises a fixing platform 10, a reinforcing rib 80 and a layer plate frame 90. A mounting box 20 is fixed on the upper end of the fixing platform 10. The mounting box 20 has openings on both sides for heat dissipation. Two rodless cylinders 30 are fixed in the inner cavity of the mounting box 20. The two rodless cylinders 30 are symmetrically fixed on the bottom wall of the inner cavity of the mounting box 20. A matching plate 40 is fixed to the output ends of the two rodless cylinders 30. The matching plate 40 slides on the top wall of the inner cavity of the mounting box 20. Among them, Figure 2As shown, a group of limiting grooves 41 are opened on the upper side of the matching plate 40, and the group of limiting grooves 41 are symmetrical about the center line of the matching plate 40, and the limiting grooves 41 on both sides are symmetrical to each other, and the distances on both sides of two adjacent limiting grooves 41 are the same, so that the distance between two adjacent limiting grooves 41 is the same as the distance between two other adjacent limiting grooves 41 at the same position; Next, a plurality of blanking parts 50 adapted to the limiting grooves 41 are slidably arranged in the inner cavity of the installation box 20. The blanking parts 50 can be evenly moved through the limiting grooves 41. A pressing part 60 is fixed at one end of each of the blanking parts 50. The pressing part 60 is used to cooperate with the blanking parts 50 to blank materials and support the reinforcing ribs 80. At the same time, the reinforcing ribs 80 are clamped during welding to prevent the movement of the reinforcing ribs 80 from affecting the welding effect. A welding part 70 is installed on one side of the fixing platform 10. The welding part 70 is used to cooperate with the pressing part 60 to weld the reinforcing ribs 80. By moving the matching plate 40 , the limiting groove 41 can move with the matching blanking component 50 , so that the reinforcing ribs 80 in the blanking component 50 are evenly distributed, thereby reducing the problem of insufficient precision caused by the uneven distribution of the reinforcing ribs 80 .

[0022] Further, if Figure 4 — Figure 6 As shown, the blanking component 50 includes a sliding block 51 sliding on the bottom wall of the inner cavity of the installation box 20, the sliding direction of the sliding block 51 is perpendicular to the moving direction of the limiting groove 41, a limiting column 57 is fixed to the upper end of the sliding block 51, the limiting column 57 is adapted to the limiting groove 41, and slides in the inner cavity of the limiting groove 41, a rodless cylinder 2 52 is fixed to the lower end of the sliding block 51, and a positioner 53 is fixed to the lower end of the rodless cylinder 2 52, the positioner 53 is used to position the two ends of the layer plate rack 90, and is used in conjunction with the rodless cylinder 1 30 to make the blanking components 50 on both sides of the multiple blanking components 50 correspond to the two ends of the layer plate rack 90; Then, if Figure 6 As shown, a material discharge groove 55 is provided at one end of the sliding block 51 away from the matching plate 40, and the width of the material discharge groove 55 is the same as that of the reinforcing rib 80. A push plate 58 is slidably provided in the inner cavity of the material discharge groove 55, and the push plate 58 is used to push the reinforcing rib 80, so the width and height of the push plate 58 and the reinforcing rib 80 are the same. A connecting block 59 is fixed at the lower end of the push plate 58, and the connecting block 59 is fixedly connected to the output end of the rodless cylinder 2 52, and the connecting block 59 is used to move with the push plate 58 to push the reinforcing rib 80 out of the inner cavity of the material discharge groove 55, and a groove for sliding the push plate 58 is provided at the lower end of the sliding block 51; A cleaning wheel 54 is installed at one end of the sliding block 51. The cleaning wheel 54 is rotatably installed at one end of the sliding block 51 through two bracket plates. The cleaning wheel 54 corresponds to the material discharge trough 55 and can clean the layer plate rack 90 coming out of the material discharge trough 55 to remove dust and impurities on the surface of the layer plate rack 90 to avoid affecting the welding effect. Next, a material box 56 communicating with the inner cavity of the material trough 55 is fixed to the upper end of the sliding block 51. The inner cavity of the material box 56 can hold multiple reinforcing ribs 80. Multiple welding operations can be performed after one replenishment, saving time for manual loading. Reinforcing ribs 80 are placed in the inner cavity of the material box 56.

[0023] Further, if Figure 7 As shown, the pressing component 60 includes a pushing cylinder 61, which is fixed to one end of the unloading box 56, and a connecting rod 62 is fixed to the output end of the pushing cylinder 61. A plurality of supporting and clamping components 63 are fixed to one end of the connecting rod 62. The supporting and clamping components 63 are used to support the reinforcing rib 80 and can also clamp the reinforcing rib 80. The plurality of supporting and clamping components 63 are connected to each other through a connecting plate, and the pushing cylinder 61 is used to control the plurality of supporting and clamping components 63 to move downward, so that the reinforcing rib 80 can contact with the layer frame 90 and be stable and not move; Then, if Figure 8 As shown, the supporting clamping component 63 includes a mounting block 631 fixedly connected to the connecting rod 62, and a plurality of mounting blocks 631 are fixedly connected by a connecting plate. A micro motor 632 is fixed to the upper end of the mounting block 631, and the micro motor 632 is a servo motor that can rotate forward and reverse. Two fixing plates 633 are fixed to the lower end of the mounting block 631, and the two fixing plates 633 are symmetrical to each other. Furthermore, a screw rod 634 is rotatably connected between the two fixing plates 633, and the screw rod 634 penetrates the two fixing plates 633 and is rotatably connected between the two fixing plates 633. The two screw rods 634 are threadedly connected with a clamping block 639 that is slidably connected to the mounting block 631. The rotation of the two screw rods 634 can make the two clamping blocks 639 move toward each other or in opposite directions. Screw rods 635 are fixed at both ends of the screw rod 634, and the thread grooves of the screw rod 635 and the screw rod 634 are different. The screw rod 634 is connected to the output end of the micro motor 632 through a belt. A pulley is fixed to the output end of the micro motor 632. A pulley is fixed to the middle of the screw rod 634. Belts are wound around the two pulleys. A through groove for installing the belt is opened at the upper end of the mounting block 631. The outer surfaces of the two screw rods 635 are threadedly connected with a moving plate 636 that is slidably connected to the mounting block 631. The two screw rods 635 can rotate to move the two moving plates 636 toward each other or in opposite directions. The ends of the two moving plates 636 that are close to each other are slidably connected to a supporting block 637. The support block 637 slides up and down at the connection with the moving plate 636. The shape of the support block 637 is a straight part plus an inclined part. The upper side of the inclined part is in contact with the lower side of the clamping block 639. Fig. 9 As shown, the upper end of the straight portion of the support block 637 is aligned with the bottom end of the reinforcing rib 80 coming out of the feed chute 55, so that the reinforcing rib 80 can slide on the straight portion of the support block 637, and the two ends of the two support blocks 637 are fixed with a positioning column 638, and the positioning column 638 is fixed to the inclined portion of the support block 637; In addition, two connecting frames 641 are fixed at both ends of the mounting block 631, and a slot block 640 adapted to the positioning column 638 is fixed at one end of the two connecting frames 641 on the same side. The positioning column 638 slides in the inner cavity of the slot block 640, and the shape of the inner cavity of the slot block 640 is also an inclined part and a straight part; like Fig.10 As shown, when the positioning column 638 moves in the straight portion of the inner cavity of the slot block 640, the straight portion of the support block 637 can be moved away from the lower side of the reinforcing rib 80, and then the positioning column 638 moves along the inclined portion of the slot block 640, so that the support block 637 can be moved upward, so that the lower end of the straight portion of the support block 637 is not on the same plane as the lower end of the reinforcing rib 80, which facilitates the contact between the reinforcing rib 80 and the inner cavity of the layer frame 90; Among them, multiple supporting clamping parts 63 are started in pairs, and the two supporting clamping parts 63 that cooperate are the supporting clamping parts 63 on both sides, which prevent the two supporting clamping parts 63 from being too close to each other and unable to form effective support for the reinforcing rib 80. It can ensure that when a supporting block 637 is separated from the lower end of the reinforcing rib 80, there are still other supporting blocks 637 to support the reinforcing rib 80. At the same time, when the supporting blocks 637 in the two supporting clamping parts 63 that are started first are fully raised, the clamping blocks 639 in the two supporting clamping parts 63 can also clamp the reinforcing rib 80, and the remaining supporting clamping parts 63 can be activated. Example 2

[0024] This embodiment further defines the welding component 70 on the basis of the first embodiment, so as to achieve the purpose of centering and clamping the layer frame 90 .

[0025] Specifically, Fig.11 and Fig.12 As shown, the welding component 70 includes a mounting platform 71, and two hydraulic cylinders 72 are fixed on the upper end of the mounting platform 71. The two hydraulic cylinders 72 are symmetrical, and an operating platform 73 is commonly provided at the output ends of the two hydraulic cylinders 72. A U-shaped frame is hinged at the output ends of the two hydraulic cylinders 72, and the U-shaped frame is fixedly connected to the lower end of the operating platform 73. In order to ensure that the two hydraulic cylinders can synchronously lift the object, there is a control system to accurately adjust the working state of the two hydraulic cylinders 72, which is a prior art; Next, a two-way synchronous cylinder 76 is fixed at the lower end of the operating table 73. The two-way synchronous cylinder 76 is a prior art, and its two output ends can move toward each other or in opposite directions. A clamping plate 75 is fixed to the two output ends of the two-way synchronous cylinder 76. The two output ends of the two-way synchronous cylinder 76 are fixedly connected to the clamping plate 75 through a connecting slider. A groove for sliding the connecting slider is provided on the operating table 73, so that the two clamping plates 75 can be centrally clamped. A rotating plate 74 is rotatably connected to one of the clamping plates 75. After the two clamping plates 75 clamp the layer plate frame 90 in the center, the center line of the layer plate frame 90 and the center line of the matching plate 40 can be aligned in a straight line, so that when the matching plate 40 moves, multiple blanking components 50 can be driven to be evenly distributed on the upper side of the layer plate frame 90; Next, a spot welder 77 is fixed to one end of the mounting platform 71 through a connecting column. The spot welder 77 is a prior art and is used to weld the fixed reinforcing ribs 80 and the layer frame 90 . The layer frame 90 is placed on the upper end of the operating platform 73 .

[0026] It should be noted that the rodless cylinder 1 30, rodless cylinder 2 52, positioner 53, micro motor 632, hydraulic cylinder 72, bidirectional synchronous cylinder 76 and spot welding machine 77 in the present invention are all prior arts, and their installation methods and control methods are also conventional designs, which will not be elaborated in detail in the present invention.

[0027] The working principle of the present invention is as follows: when in use, firstly, the plate rack 90 is placed on the upper end of the operating table 73, and the two-way synchronous cylinder 76 moves the two clamping plates 75 toward each other to clamp the plate rack 90 in the center, and then, the operating table 73 is lifted up by starting the two hydraulic cylinders 72, so that the plate rack 90 can be close to the pressing component 60; Next, the two rodless cylinders 30 are started to push the matching plate 40. Under the action of the multiple limit grooves 41, the multiple sliding blocks 51 begin to move, so that the multiple sliding blocks 51 can be evenly distributed. At the same time, the positioners 53 on the lower sides of the two sliding blocks 51 on both sides correspond to the two ends of the layer frame 90, so that the rodless cylinder 30 stops moving. At this time, the multiple sliding blocks 51 are evenly distributed on the upper side of the layer frame 90 with the pressing parts 60, as shown in FIG. Fig.13 As shown; Then, except for the unloading parts 50 used for positioning on both sides, the output ends of the rodless cylinder 2 52 in the other unloading parts 50 move with the push plate 58 and the connecting block 59 to push the reinforcing rib 80 in the inner cavity of the unloading trough 55 from the inner cavity of the unloading trough 55 to the side of the pressing part 60. In the process of the reinforcing rib 80 moving out, the cleaning wheel 54 fixed at one end of the sliding block 51 can clean the surface of the reinforcing rib 80 to remove dust and impurities to avoid affecting the subsequent welding of the reinforcing rib 80. At the same time, the automatic unloading of the reinforcing rib 80 can also avoid the problem of manual loading delaying the welding time, thereby improving the production efficiency of the device; Then, if Fig. 9 As shown, the reinforcing rib 80 pushed out from the inner cavity of the feeding chute 55 enters into the plurality of supporting and clamping components 63, and the straight portions of the two supporting blocks 637 in the supporting and clamping components 63 support the reinforcing rib 80, so that the reinforcing rib 80 can move to the straight portions of the supporting blocks 637 of the plurality of supporting and clamping components 63, and the distance that the pushing plate 58 pushes the reinforcing rib 80 to move corresponds to the length of the inner cavity of the layer plate rack 90; When the reinforcing rib 80 enters between the plurality of supporting and clamping components 63, as shown in FIG. Fig.10 As shown, the supporting clamping parts 63 on both sides are first started, and the micro motor 632 drives the screw rod 1 634 to rotate, so that the screw rod 2 635 rotates accordingly, so that the clamping blocks 639 on the two screw rods 1 634 gradually approach each other until the reinforcing rib 80 is clamped, and the moving plates 636 on the two screw rods 2 635 gradually move away from each other; When the two moving plates 636 move away from each other, under the action of the inner cavities of the two slot blocks 640 on the same side, the two support blocks 637 first translate and then move along the inclined direction of the inner cavities of the slot blocks 640, so that the lower ends of the support blocks 637 and the lower ends of the reinforcing ribs 80 are not in the same plane, which will not affect the contact between the reinforcing ribs 80 and the layer frame 90; Then, after two support clamping parts 63 clamp the reinforcing rib 80, the remaining support clamping parts 63 start to clamp the reinforcing rib 80, which can ensure that the reinforcing rib 80 can be stably supported and will not lose support during the movement of the support blocks 637 in the support clamping parts 63 on both sides; Next, by pushing the cylinder 61 to move the connecting rod 62 downward, the multiple supporting clamping parts 63 are moved downward, and the lower ends of the clamped reinforcing ribs 80 can contact the bottom wall of the inner cavity of the layer frame 90, so as to avoid the reinforcing ribs 80 from moving during manual operation, thereby causing insufficient welding accuracy of the reinforcing ribs 80, and then the spot welding machine 77 is started to weld the multiple uniformly distributed reinforcing ribs 80; Through the action of multiple supporting and clamping components 63, multiple reinforcing ribs 80 are evenly distributed in the inner cavity of the shelf rack 90, and the distance between each of the multiple reinforcing ribs 80 is equal. The evenly distributed reinforcing ribs 80 can improve the structural strength and durability of the shelf shelves and reduce safety hazards.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes to a welding device for forming shelf layers and its inventive concept according to the technology of the present invention, which should be covered by the protection scope of the present invention.
