Description

Technical Field

[0001] The present invention relates to the technical field of production equipment, and particularly relates to a plate-frame combined production system. Background Art

[0002] Existing plate frames are usually used in the construction industry. Multiple plate frames can be spliced together to form a scaffolding for workers to operate. This kind of plate frame splicing has the advantages of easy installation, easy disassembly, and firm combination. A single plate frame is usually assembled by a frame and a mesh frame, and the frame is formed by splicing and welding multiple aluminum profiles. In existing plate frame production enterprises, in order to save costs, the frame and the mesh frame are usually produced separately. In the frame production line, after the long profiles are cut, workers use positioning tools to place the profiles into the shape of the frame and then weld them. After welding the frame, the frame is put on the line again. In order to facilitate the installation of the mesh frame, the frame is first erected by a lifting device, and then the mesh frame is placed on the side of the plate frame by using a limiting groove, and then the frame and the mesh frame are nailed and installed. During this process, the assembly of the frame and the mesh frame cannot achieve continuous production, and both the intermediate frame welding process and the mesh frame assembly process require certain manual intervention, with low overall automation and serious restriction on production efficiency.

[0027] To make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the terms indicating orientations such as up, down, left, right, front, back, inside and outside that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention and do not specifically limit the present invention.

[0028] See Figure 1 and Figure 2 , an embodiment of the present invention discloses a plate-frame combined production system for assembling profiles 10, lugs and a mesh frame 30 into a plate-frame 40, including a feeding device 1, a cutting device 2, a material separating device 3, a material arranging and welding device 4, a lug welding device 5, a plate-frame assembling device 6 and a discharging device 7 arranged in sequence along the front-back direction. The feeding device 1 is used for feeding the raw material of the profile 10, the cutting device 2 is used for cutting the raw material of the profile 10 with a longer length, the material separating device 3 is used for separating the cut small sections of the profile 10, the material arranging and welding device 4 is used for arranging and welding the profile 10 into a frame 20, the lug welding device 5 is used for welding the lug and the frame 20 together, the plate-frame assembling device 6 is used for nailing the frame 20 and the mesh frame 30 together, and the discharging device 7 is used for packing and discharging. The feeding device 1 includes a feeding component 11 and a material storage component 12. The raw material of the profile 10 is placed on the feeding component 11. The feeding component 11 is connected to the material storage component 12. The outlet of the material storage component 12 is connected to the inlet of the cutting device 2. The cutting device 2 is used for cutting the raw material of the profile 10 into multiple sections of the profile 10. The feeding component 11 transfers the raw material of the profile 10 to the material storage component 12 one by one, and the material storage component 12 feeds the raw material of the profile 10 into the cutting device 2. The cutting device 2 cuts the raw material of the profile 10 by means of laser cutting. After cutting, the raw material of the profile 10 with a longer length forms multiple sections of the profile 10 with a shorter length.

[0029] See Figure 3 and Figure 4, the outlet of the cutting device 2 is connected to the material distribution device 3. The material distribution device 3 includes a material distribution mechanism 31 and a plurality of material distribution grooves 32. In order to enable the multi-segment profiles 10 to be regularly arranged, the distribution direction of the material distribution grooves 32 is perpendicular to the length direction of the profiles 10. The material distribution mechanism 31 can move in a direction perpendicular to the length of the profiles 10, so that the material distribution mechanism 31 can distribute the multi-segment profiles 10 into each of the material distribution grooves 32, enabling the multi-segment profiles 10 to be arranged at designated positions, facilitating the subsequent pick-and-place welding device 4 to precisely pick up each segment of the profiles 10. The pick-and-place welding device 4 includes a pick-and-place component 42 and a first welding component 41. The pick-and-place component 42 is arranged between the material distribution device 3 and the first welding component 41. The pick-and-place component 42 includes a first clamp 421 and a carrier plate 422. The first clamp 421 can place the profiles 10 in the material distribution grooves 32 on the carrier plate 422 according to a preset position. The first clamp 421 can rotate, can pick up the profiles 10 from the material distribution device 3 and rotate by a certain angle, so that the profiles 10 can be placed on the carrier plate 422. The first welding component 41 includes a first welding head 411, and the first welding head 411 is used to weld the profiles 10 into a frame 20.

[0030] See Figure 5 , the lug welding device 5 includes a second clamp 51, a first conveying component 52 and a second welding component 53. The second clamp 51 can move between the carrier plate 422 and the first conveying component 52. The first conveying component 52 has a movable chain, and the frame 20 can be placed on the chain. The second clamp 51 can clamp and place the frame 20 onto the first conveying component 52. After placing, the vibrating bucket automatically transfers the lugs to the side of the frame 20. Then, the second welding component 53 can weld the lugs to the frame 20. The plate-frame assembly device 6 includes a second conveying component 61, and the first conveying component 52 can transfer the frame 20 with welded lugs to the second conveying component 61.

[0031] See Figure 6, the plate-frame assembly device 6 further includes a screen-frame storage bin 62, a third fixture 63, and a nailing assembly 64. The screen frames 30 are stored in the screen-frame storage bin 62. The third fixture 63 is disposed between the screen-frame storage bin 62 and the second conveying assembly 61. The third fixture 63 can lay the screen frames 30 on the frame 20. The nailing assembly 64 is disposed above the second conveying assembly 61. The second conveying assembly 61 has a movable conveyor belt. By using the conveyor belt, the second conveying assembly 61 can move the frame 20 and the screen frames 30 in the direction of the discharging device 7. When the frame 20 and the screen frames 30 are moving, the nailing assembly 64 can nail the frame 20 and the screen frames 30 into a plate-frame 40, thus completing the automated production of the plate-frame 40. After the production is completed, the discharging device 7 packs and discharges the plate-frame 40.

[0032] The beneficial effects of the embodiments of the present invention are as follows:

[0033] The plate-frame combined production system of the embodiments of the present invention is provided with a feeding device 1, a cutting device 2, a material distributing device 3, a material arranging and welding device 4, an ear welding device 5, a plate-frame assembly device 6, and a discharging device 7. Among them, the raw material length of the profile 10 is relatively long. The raw material of the long-strip profile 10 is placed on the feeding assembly 11 of the feeding device 1. Then, the raw material of the profile 10 enters the cutting device 2 for cutting, and the profile 10 becomes short segments. The short segments of the profile 10 are distributed by the material distributing mechanism 31 in the material distributing device 3 into each material distributing groove 32. Then, the first fixture 421 of the material arranging and welding device 4 places each profile 10 in the carrying tray 422 and arranges them in the preset positions. Then, the first welding assembly 41 welds the profiles 10 to form the frame 20. The welded frame 20 is clamped by the second fixture 51 of the ear welding device 5 and sent to the first conveying assembly 52. On the first conveying assembly 52, the second welding assembly 53 can weld the ears to the frame 20. After the welding is completed, the first conveying assembly 52 moves the frame 20 to the second conveying assembly 61 of the plate-frame assembly device 6. Finally, on the plate-frame assembly device 6, the frame 20 and the screen frames 30 are nailed by the third fixture 63 and the nailing assembly 64. After the nailing, the discharging device 7 transports the plate-frame 40 out of the production line. During the production process, the placement and welding of the frame 20, and the nailing of the frame 20 and the screen frames 30 are all automatically completed by the equipment, with a high degree of automation, which can greatly improve the overall production efficiency.

[0034] Specifically, the loading component 11 includes a loading conveyor belt 111, the storage component 12 includes a pushing mechanism 121 and a storage frame 122. The raw material of the profile 10 is placed in the loading conveyor belt 111, and the loading conveyor belt 111 extends into the storage frame 122 and is driven by a driving motor. The loading conveyor belt 111 can move in a cyclic and reciprocating manner, so as to horizontally transfer the raw material of the long profile 10 into the storage frame 122. The pushing mechanism 121 is arranged on the side of the storage frame 122, and the pushing mechanism 121 can move reciprocally along the length direction of the storage frame 122. The pushing mechanism 121 can abut against the end of the profile 10 raw material and push the profile 10 raw material into the cutting device 2. The cutting device 2 cuts the profile 10 raw material section by section, and finally divides the long profile 10 raw material into multiple shorter profiles 10.

[0035] In order to drive the movement of the profile 10, the material distribution device 3 further includes a moving roller path 33. The setting direction of the moving roller path 33 is parallel to the length direction of the profile 10. The moving roller path 33 can transfer the profile 10 into the material distribution groove 32. The material distribution mechanism 31 includes a moving rail 311 and a dial rod 312. The dial rod 312 can move on the moving rail 311. The setting direction of the moving rail 311 is perpendicular to the length direction of the profile 10. The material distribution groove 32 is arranged at one end of the moving roller path 33 close to the swinging and welding device 4. Therefore, the dial rod 312 can place the profiles 10 one by one in the direction perpendicular to the length of the profile 10 on the moving roller path 33, which is convenient for subsequent clamping of the profiles 10 one by one, saves the length space occupied by the profiles 10, and improves the space utilization rate of the moving roller path 33.

[0036] In order to improve the efficiency of placing materials, the material placing assembly 42 further includes a chassis 423 and a rotation mechanism 424. The rotation mechanism 424 is arranged at the bottom of the chassis 423. The rotation mechanism 424 can drive the chassis 423 to rotate horizontally. The number of the bearing plates 422 is two and they are respectively arranged at the front and rear ends of the chassis 423. In this way, the rotation mechanism 424 can drive different bearing plates 422 to stay at the front and rear ends of the chassis 423 in turn, so as to facilitate placing the profiles 10 on different bearing plates 422. Specifically, the first clamp 421 places the profiles 10 on the material distribution groove 32 one by one on the bearing plate 422 at the front end of the chassis 423. After placing them in the preset positions, the rotation mechanism 424 can drive the chassis 423 to rotate, so that the bearing plate 422 at the rear end of the chassis 423 moves to the front end of the chassis 423. The first clamp 421 continues to place the profiles 10 on the material distribution groove 32 one by one on this bearing plate 422. At the same time, the bearing plate 422 that has loaded the profiles 10 in the preset positions at the front end of the chassis 423 is transferred to the rear end of the chassis 423. At this time, the first welding assembly 41 welds the profiles 10 on this bearing plate 422, so that welding and material placing can be carried out simultaneously, which improves the assembly efficiency.

[0037] After welding the profiles 10 into the frame 20, the lug welding device 5 welds lugs on the frame 20. In order to place the frame 20, the lug welding device 5 further includes a workbench 54. The first conveying assembly 52 includes a first-direction chain 521 and a second-direction chain 522. The first-direction chain 521 and the second-direction chain 522 are perpendicular to each other. The first-direction chain 521 is respectively arranged on both sides of the workbench 54. The second-direction chain 522 is arranged on both sides of the workbench 54 perpendicular to the first-direction chain 521, so that the first-direction chain 521 and the second-direction chain 522 form a square frame body capable of bearing the frame 20. The first-direction chain 521 is connected to a driving motor. The first-direction chain 521 can drive the frame 20 to move in two opposite directions. The second-direction chain 522 is connected to a driving motor. The second-direction chain 522 can drive the frame 20 to move in two directions perpendicular to the first-direction chain 521. Therefore, the first-direction chain 521 and the second-direction chain 522 can cooperate to drive the frame 20 to move on the workbench 54 to cooperate with the welding of lugs and improve the convenience of lug welding.

[0038] The lug welding device 5 further includes a positioning and rotating mechanism 55 and a lifting mechanism 56. The positioning and rotating mechanism 55 is arranged at the bottom of the workbench 54. The positioning and rotating mechanism 55 can drive the workbench 54 to rotate. When rotating, different positions of the frame 20 can be aligned with the second welding assembly 53, so that the second welding assembly 53 can weld the lugs at preset positions in the frame 20.

[0039] In addition, in order to prevent the frame 20 from automatically moving towards the second conveying assembly 61 and for limiting purposes, the lifting mechanism 56 is arranged at the bottom of the second direction chain 522. The lifting mechanism 56 can drive the second direction chain 522 to lift and lower. When welding the lugs, the second direction chain 522 is in a lower position. After welding is completed, through the rotation of the workbench 54, the second direction chain 522 faces the second conveying assembly 61. Subsequently, the lifting mechanism 56 drives the second direction chain 522 to rise, the frame 20 rises, and then the first direction chain 521 is driven to enable the frame 20 to enter the second conveying assembly 61.

[0040] See Figure 7 , the second conveying assembly 61 includes a front guide plate 611. The front guide plate 611 is arranged on both sides of the second conveying assembly 61. The height of the front guide plate 611 is higher than the height of the second direction chain 522 before the lifting mechanism 56 raises it. Therefore, before the lifting mechanism 56 drives the second direction chain 522 to rise, the frame 20 cannot enter the front guide plate 611, thus playing a role in preventing the frame 20 from entering the second conveying assembly 61 in advance. In addition, a guiding inclined surface 612 is provided at one end of the front guide plate 611 close to the lug welding device 5. The guiding inclined surface 612 inclines towards the outside of the second conveying assembly 61. By using the guiding inclined surface 612, it can be ensured that the frame 20 can enter the second conveying assembly 61 at a specified position, facilitating subsequent installation and cooperation with the mesh frame 30.

[0041] The mesh frame storage bin 62 is arranged at the side of the second conveying assembly 61. The plate frame assembly device 6 further includes a moving frame 65. The moving frame 65 spans between the mesh frame storage bin 62 and the second conveying assembly 61. The third fixture 63 can move on the moving frame 65, so that the mesh frame 30 can be clamped and placed from the mesh frame storage bin 62 onto the frame 20 of the second conveying assembly 61. The nailing assembly 64 is arranged between the second conveying assembly 61 and the discharging device 7. After the second conveying assembly 61 completes nailing, the second conveying assembly 61 transports the assembled plate frame 40 out to the discharging device 7.

[0042] See Figure 8, the discharging device 7 includes a fourth fixture 71, a discharging roller path 72 and a packing mechanism 73. The fourth fixture 71 is arranged between the plate-frame assembling device 6 and the discharging roller path 72, and can transfer the assembled plate-frame 40 from the plate-frame assembling device 6 to the discharging roller path 72. The packing mechanism 73 straddles both sides of the discharging roller path 72. The fourth fixture 71 can place the plate-frame 40 in the discharging roller path 72, and the packing mechanism 73 can pack the plate-frame 40 and finally discharge it.

[0043] The above are the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
