Description

Technical Field

[0001] The present invention relates to the technical field of machining, and particularly relates to a hemming machine. Background Art

[0002] In the prior art, many plate structures include a plate and a hemming strip. The plate is specifically a mesh plate or a solid plate, and the hemming strip is coated on the periphery of the plate. In the existing processing technology of such plate structures, manual hemming is usually required, which not only consumes labor but also has extremely low efficiency.

[0003] There are also hemming machines in the prior art for hemming mesh plates. The hemming device of such a hemming machine includes a mesh grabbing part and a moving part. The mesh grabbing part is used to grab the plate to be hemmed, and the moving part is used to drive the mesh grabbing part to move. The hemming strip includes a plurality of hemming segments connected in sequence and corresponding to the respective side edges of the plate to be hemmed one by one. The hemming strip also has a V-shaped or U-shaped hemming groove for the side edge of the plate to be inserted. During hemming, the moving part drives the mesh grabbing part to roll the grabbed plate along the length direction of the hemming strip, and when rolling, the side edges of the plate are inserted into the corresponding hemming segments and the hemming segments can follow the plate to flip and move together, so as to hem the respective side edges of the plate in sequence, and the hemming efficiency is relatively low. In addition, since the hemming device needs to continuously clamp the plate and drive the plate to roll vertically during hemming, the mesh grabbing part needs to be moved away from the corresponding side edge of the plate to make way for the hemming strip when inserting the side edge of the plate into the corresponding hemming segment, and the mesh grabbing part also needs to drive the hemming segment to follow the plate to flip and move together after the plate is inserted into the hemming segment, resulting in a relatively complex structure of the mesh grabbing part and a relatively complex and cumbersome hemming process for the entire plate. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. For this purpose, the present invention provides a hemming machine, which can facilitate hemming of plates and has a high working efficiency.

[0005] The edge banding machine according to an embodiment of the present invention includes: a frame provided with a workbench; a first carrier seat disposed on the workbench and used for carrying a plate member. The plate member has a first side edge, two second side edges, and a third side edge. The first side edge is located at the front side of the plate member, the two second side edges are correspondingly connected to both ends of the first side edge, and the third side edge is connected between the two second side edges and is located at the rear side of the plate member; a second carrier seat disposed on the front side of the first carrier seat and used for carrying an edge banding strip. The edge banding strip includes a first edge banding section, two second edge banding sections, and two third edge banding sections. The two second edge banding sections are correspondingly connected to both ends of the first edge banding section, and the two third edge banding sections are correspondingly connected to the two second edge banding sections. The first edge banding section corresponds to the first side edge, the two second edge banding sections correspond to the two second side edges one by one, and both of the two third edge banding sections can cover the third side edge; a bending mechanism movably installed on the frame; when the plate member is placed on the first carrier seat and the edge banding strip is placed on the second carrier seat, the first side edge, the second side edges, and the third side edge all protrude from the first carrier seat, and the first side edge and the first edge banding section are arranged oppositely; the bending mechanism can simultaneously push the two second edge banding sections to bend relative to the first edge banding section and correspondingly cover the two second side edges, and the bending mechanism can also simultaneously push the two third edge banding sections to bend relative to the corresponding second edge banding sections and cover the third side edge.

The edge banding strip is fixed on the second carrier seat, and the first edge banding section is arranged oppositely to the first side edge of the plate member. Thus, it is convenient to cover the first side edge of the plate member with the first edge banding section. Since the two second edge banding sections are correspondingly connected to both ends of the first edge banding section and the two third edge banding sections are correspondingly connected to the two second edge banding sections, the bending mechanism can simultaneously push the two second edge banding sections to bend relative to the first edge banding section and correspondingly cover the two second side edges, and can also simultaneously push the two third edge banding sections to bend relative to the corresponding second edge banding sections and cover the third side edge.

[0047] Referring to Figures 1 to 4 , an edge wrapper is proposed in an embodiment of the present invention. The edge wrapper is used to wrap an edge strip 800 around the outer periphery of a plate member 700. Among them, the plate member 700 has a first side 710, two second sides 720, and a third side 730. The first side 710 is located on the front side of the plate member 700. The two second sides 720 are correspondingly connected to both ends of the first side 710. The third side 730 is connected between the two second sides 720 and is located on the rear side of the plate member 700. The edge strip 800 includes a first edge wrapping section 810, two second edge wrapping sections 820, and two third edge wrapping sections 830. The two second edge wrapping sections 820 are correspondingly connected to both ends of the first edge wrapping section 810. The two third edge wrapping sections 830 are correspondingly connected to the two second edge wrapping sections 820. The first edge wrapping section 810 corresponds to the first side 710 and can wrap around the first side 710. The two second edge wrapping sections 820 correspond one-to-one with the two second sides 720 and can wrap around the corresponding second sides 720. The two third edge wrapping sections 830 can jointly wrap around the third side 730. After edge wrapping, the two third edge wrapping sections 830 are arranged side by side.

[0048] Referring to Figures 1 to 4, an embodiment of the present invention provides a hemming machine, which includes a first carrier 130, a second carrier 140 and a bending mechanism. The first carrier 130 is disposed on the workbench 110 and is used to carry the plate member 700; the second carrier 140 is disposed on the front side of the first carrier 130 and is used to carry the hemming strip 800; the bending mechanism is movably installed on the frame 100; when the plate member 700 is placed on the first carrier 130 and the hemming strip 800 is placed on the second carrier 140, the first side 710, the second side 720, and the third side 730 all protrude from the first carrier 130, and the first side 710 is arranged opposite to the first hemming section 810; the bending mechanism can simultaneously push the two second hemming sections 820 to bend relative to the first hemming section 810 and correspondingly cover the two second sides 720, and the bending mechanism can also simultaneously push the two third hemming sections 830 to bend relative to the corresponding second hemming sections 820 and cover the third side 730.

[0049] In the hemming machine according to the embodiment of the present invention, by dividing the hemming strip 800 into a first hemming section 810, two second hemming sections 820 and two third hemming sections 830, when bending, the plate member 700 can be fixed on the first carrier 130, and each side of the plate member 700 protrudes from the first carrier 130, the hemming strip 800 is fixed on the second carrier 140, and the first hemming section 810 is arranged opposite to the first side 710 of the plate member 700, so that it is convenient to cover the first hemming section 810 on the first side 710 of the plate member 700. Since the two second hemming sections 820 are correspondingly connected to both ends of the first hemming section 810, and the two third hemming sections 830 are correspondingly connected to the two second hemming sections 820, the bending mechanism can simultaneously push the two second hemming sections 820 to bend relative to the first hemming section 810 and correspondingly cover the two second sides 720, and can also simultaneously push the two third hemming sections 830 to bend relative to the corresponding second hemming sections 820 and cover the third side 730. Thus, the bending and hemming of the two second hemming sections 820 and the two third hemming sections 830 can be realized. In this process, it is not necessary to bend each hemming section in sequence. The second hemming sections 820 on both sides of the first hemming section 810 can be bent simultaneously, and the third hemming sections 830 at the outer ends of the two second hemming sections 820 can also be bent simultaneously, thereby greatly improving the hemming efficiency of the hemming machine.

[0050] In addition, when the edge bender according to the embodiment of the present invention performs edge bending, it only needs to fix the plate member 700 on the first bearing seat 130. Then, the bending mechanism is used to push the second edge bending section 820 and the third edge bending section 830 to bend and wrap around the respective side edges of the plate member 700. The whole process is simple and convenient. Compared with the prior art, the edge bender according to the embodiment of the present invention does not need to flip the plate member 700, nor does it need to consider whether the corresponding edge bending section will be synchronously flipped when the plate member 700 is edge-bent and whether it will be separated from the edge strip 800. Therefore, the fixing structure of the plate member 700 can be simplified, the edge bending of the plate member 700 can be made more convenient and fast, and thus the manufacturing cost of the edge bender can be reduced, the production and manufacturing of the edge bender can be facilitated, and the edge bending efficiency of the plate member 700 can be further improved.

[0051] Referring to Figure 1 and Figure 2 , the edge strip 800 is provided with an edge bending groove 850 for inserting the side edge of the plate member 700. The first edge bending section 810 wrapping around the first side edge 710 of the plate member 700 specifically means that the first side edge 710 is inserted into the edge bending groove 850 on the first edge bending section 810. The second edge bending section 820 wrapping around the corresponding second side edge 720 specifically means that the second side edge 720 is inserted into the edge bending groove 850 on the second edge bending section 820. The third edge bending section 830 wrapping around the third side edge 730 specifically means that the third side edge 730 is inserted into the edge bending groove 850 of the third edge bending section 830.

[0052] Referring to Figure 1 and Figure 2 , in order to facilitate the bending of the edge strip 800, in some embodiments, bending notches 840 are provided between the first edge bending section 810 and the two second edge bending sections 820, and between the two second edge bending sections 820 and the corresponding third edge bending sections 830. Thereby, the thrust required for bending the edge strip 800 can be reduced, the bending of the edge strip 800 can be made more convenient, and thus the edge bending efficiency of the plate member 700 can be greatly improved.

[0053] It can be understood that in the implementation of the present invention, when hemming the first side 710 of the plate member 700, it can be that when the hemming strip 800 is placed on the second carrier 140, the first hemming section 810 is arranged opposite to the first side 710 and directly covers the first side 710, and then the second hemming section 820 and the third hemming section 830 are bent to cover the second side 720 and the third side 730. In this process, the second hemming section 820 can be bent first, or the third hemming section 830 can be bent first, and both methods can achieve hemming of each side of the plate member 700. In addition, it can also be that when the hemming strip 800 is placed on the second carrier 140, the first hemming section 810 is arranged opposite to the first side 710 and has a gap. At this time, the first hemming section 810 can be first pushed to move to cover the first side 710, and then the second hemming section 820 and the third hemming section 830 are bent; or the two second hemming sections 820 can be bent first, and then the first hemming section 810 is pushed to move to cover the first side 710, and the second hemming section 820 is made to cover the corresponding second side 720, and finally the third hemming section 830 is bent; or, the two third hemming sections 830 can be bent first, and then the first hemming section 810 is pushed to move to cover the first side 710, and finally the second hemming section 820 is bent to cover the corresponding second side 720, and the third hemming section 830 follows the second hemming section 820 to move to cover the third side 730. The present invention does not specifically limit the specific hemming sequence of the first hemming section 810, the second hemming section 820, and the third hemming section 830, nor does the present invention specifically limit the specific bending sequence of the second hemming section 820 and the third hemming section 830.

[0054] Referring to Figures 3 to 5 , in some embodiments, a bearing groove 141 adapted to the outer shape of the hemming strip 800 is formed on the side of the second carrier 140 facing the first carrier 130. Thus, the hemming strip 800 can be stably placed in the bearing groove 141, making the placement of the hemming strip 800 more stable.

[0055] It can be understood that referring to Figure 3 and Figure 4, in some embodiments, the number of the second bearing seats 140 is two, and the two second bearing seats 140 are arranged at intervals, so as to avoid angular deviation or position deviation when the edge wrapping strip 800 is placed on the workbench 110 and being unable to align with the first side edge 710 of the plate member 700 on the first bearing seat 130. Furthermore, the accuracy of wrapping the edge wrapping strip 800 around the side edge of the plate member 700 can be improved. It should be noted that the number of the second bearing seats 140 can be one, three, four or more in addition to two. When the number of the second bearing seats 140 is one, the second bearing seat 140 can be arranged to extend along the left-right direction of the workbench 110. When the number of the second bearing seats 140 is two or more, each of the second bearing seats 140 can be arranged in sequence along the left-right direction of the workbench 110.

[0056] Refer to Figure 3 and Figure 4 , in some embodiments, a limiting block 150 is further provided on the workbench 110. The limiting block 150 can be stuck at the end of the edge wrapping strip 800, that is, the end of the third edge wrapping section 830, so as to limit the edge wrapping strip 800 in the left-right direction of the workbench 110, which is beneficial to improving the accuracy and stability of the subsequent bending process of the edge wrapping strip 800.

[0057] Refer to Figures 3 to 8 , in some embodiments, the bending mechanism includes a first bending assembly and a second bending assembly. Both the first bending assembly and the second bending assembly include two bending devices 200. The two bending devices 200 of the first bending assembly correspond to the two second edge wrapping sections 820 one by one, so that the two second edge wrapping sections 820 can be bent synchronously through the first bending assembly. The two bending devices 200 of the second bending assembly correspond to the two third edge wrapping sections 830 one by one, so that the two third edge wrapping sections 830 can be bent synchronously through the second bending assembly.

[0058] If the same set of bending assembly is used to bend the second edge wrapping section 820 and the third edge wrapping section 830, it is necessary to reserve time for the bending assembly to adjust the position or angle between bending the second edge wrapping section 820 and bending the third edge wrapping section 830, which will further lead to a reduction in the edge wrapping efficiency of the plate member 700. In the embodiment of the present invention, by providing independent first and second bending assemblies to bend the second edge wrapping section 820 and the third edge wrapping section 830 respectively, the third edge wrapping section 830 can be bent immediately after bending the second edge wrapping section 820, or the second edge wrapping section 820 can be bent immediately after bending the third edge wrapping section 830, thus greatly improving the working efficiency of the edge wrapping machine.

[0059] Further, refer to Figures 3 to 8, in some embodiments, the bending device 200 includes a first mounting seat 210, a first rotating mechanism, and a bending wheel 230. The first mounting seat 210 is mounted on the frame 100; the first rotating mechanism is mounted on the first mounting seat 210, and a swing arm 220 is mounted at the output end of the first rotating mechanism; the bending wheel 230 is rotatably mounted on the swing arm 220. The central axis of the bending wheel 230 is arranged at an interval from the rotating shaft of the first rotating mechanism. An annular groove 231 is formed in the outer peripheral wall of the bending wheel 230 along the circumferential direction of the bending wheel 230; the edge wrapping strip 800 can be embedded in the annular groove 231, and the first rotating mechanism can drive the bending wheel 230 to swing through the swing arm 220 and push the edge wrapping strip 800 to be bent.

[0060] By adopting the above structure, when bending the edge wrapping strip 800, the edge wrapping strip 800 is embedded in the annular groove 231 of the bending wheel 230. The first rotating mechanism can drive the bending wheel 230 to swing around the rotating shaft of the first rotating mechanism through the swing arm 220, so as to push the edge wrapping strip 800 to be bent. Among them, by setting the bending wheel 230, the bending wheel 230 can rotate relative to the edge wrapping strip 800 when pushing the edge wrapping strip 800 to be bent, thereby reducing the friction generated between the edge wrapping strip 800 and the bending wheel 230 during the bending process, making the bending of the edge wrapping strip 800 smoother, and the edge wrapping strip 800 can remain stable during the bending process, thereby improving the accuracy and efficiency of edge wrapping. By providing the annular groove 231 on the bending wheel 230, the edge wrapping strip 800 can be limited during the bending process and is not easily misaligned with the bending wheel 230 or directly separated from the bending wheel 230, so that the second edge wrapping section 820 or the third edge wrapping section 830 can be bent along a preset trajectory, which is beneficial to improving the accuracy of bending the edge wrapping strip 800 and the stability of the entire bending process.

[0061] Refer to Figure 6 and Figure 7 , in some embodiments, the first rotating mechanism includes a rotating shaft 240, a gear 241, and a first pushing device 250. The rotating shaft 240 is rotatably mounted on the first mounting seat 210; the gear 241 is arranged on the rotating shaft 240 and is coaxially arranged with the rotating shaft 240; the first pushing device 250 is mounted on the first mounting seat 210, and a rack 251 meshing with the gear 241 is arranged at the output end of the first pushing device 250; the first pushing device 250 can push the rack 251 to move and drive the gear 241 to rotate, and the gear 241 can drive the rotating shaft 240 to rotate synchronously.

[0062] By adopting the above structure, the first rotating mechanism converts the linear motion into a rotational motion through the meshing relationship between the gear 241 and the rack 251, and then drives the rotating shaft 240 to rotate. This structure has high transmission efficiency and reliable operation, which is beneficial to improving the stability of the bending process of the edge wrapping strip 800.

[0063] It is understandable that the first push device 250 can be a cylinder, an electric push rod, etc., which is not specifically limited in the present invention. In order to drive the swing arm 220 to rotate, the first drive mechanism can not only adopt the above structure, but also directly adopt a motor or other rotation drive mechanism, which is not specifically limited in the present invention.

[0064] Reference Figures 3 to 8 In some embodiments, the bending device 200 is installed below the workbench 110, and the workbench 110 is provided with a clearance hole 120 for the bending wheel 230 to extend out and move relative to the frame 100; the swing arm 220 is provided with a second pushing device 260 which is transmission-connected to the bending wheel 230, and the second pushing device 260 can drive the bending wheel 230 to move upward from the clearance hole 120 to the top of the workbench 110, or the second pushing device 260 can drive the bending wheel 230 to move downward from the clearance hole 120 to the bottom of the workbench 110.

[0065] By adopting the above structure, the bending device 200 is installed under the workbench 110, so that the bending device 200 can be hidden and protected, which not only makes the appearance of the entire hemming machine more concise, but also reduces the area of ​​the workbench 110, and facilitates the reasonable placement and layout of other mechanisms on the workbench 110 and the plates 700 and the hemming strips 800, thereby providing sufficient space for the bending of the hemming strips 800, and avoiding the bending device 200 occupying the space on the surface of the workbench 110 and interfering with or otherwise affecting the bending of the hemming strips 800. In addition, by opening a clearance hole 120 on the workbench 110, the bending wheel 230 can be flexibly moved up and down. During the specific use of the hemming machine, the bending wheel 230 can be moved to the bottom of the workbench 110 before bending the hemming strip 800, so as to facilitate the placement and positioning of the hemming strip 800. When the hemming strip 800 needs to be bent, the bending wheel 230 is moved upward to the side of the hemming strip 800 away from the hemming groove 850, and the bending wheel 230 is driven by the first rotating mechanism to swing close to the hemming strip 800 so that the hemming strip 800 is embedded in the annular groove 231 of the bending wheel 230. After that, the hemming strip 800 can continue to be pushed by the bending wheel 230 for bending and hemming.

[0066] Reference Figures 6 to 8In some embodiments, the bending device 200 also includes: a clamping portion 270, movably mounted on the first mounting seat 210, and the clamping portion 270 has a clamping groove opening upward; a third pushing device 272, which is arranged on the first mounting seat 210 and is transmission-connected to the clamping portion 270, and the third pushing device 272 can drive the clamping portion 270 to move upward or downward through the clearance hole 120; wherein, in the first bending assembly, the clamping portions 270 of the two groups of bending devices 200 are both located below the first edging section 810, and when the clamping portions 270 move upward, the first edging section 810 can be embedded in the clamping groove; in the second bending assembly, the clamping portions 270 of the two groups of bending devices 200 are correspondingly located below the two second edging sections 820, and when the clamping portions 270 move upward, the corresponding second edging sections 820 can be embedded in the clamping groove.

[0067] In the above structure, the bending device 200 is also provided with a clamping portion 270. When the second edging section 820 is bent, the clamping portion 270 in the first bending component can move upward and make the first edging section 810 embedded in the clamping groove, thereby achieving clamping and fixing of the first edging section 810, thereby facilitating the stable bending of the two second edging sections 820; when the third edging section 830 is bent, the two clamping portions 270 in the second bending component can move upward and make the two second edging sections 820 embedded in the corresponding clamping grooves, thereby achieving clamping and fixing of the two second edging sections 820, thereby facilitating the stable bending of the two third edging sections 830. In addition, the clamping portion 270 can be flexibly moved up and down relative to the workbench 110 through the clearance groove, so that before the corresponding edging section is bent, the clamping portion 270 can be moved to the bottom of the workbench 110, thereby facilitating the placement and positioning of the edging strip 800, and the clamping portion 270 can be moved upward when bending is required.

[0068] It is understandable that, referring to Figures 6 to 8 In some embodiments, the clamping portion 270 specifically includes two clamping columns 271 , and the clamping groove is located between the two clamping columns 271 . The structure is simple and can stably clamp the edging strip 800 .

[0069] Reference Figure 8, in some embodiments, the first clamping assembly further specifically includes a first slide rail 280 and a second slide rail 290. The first slide rail 280 is installed on the frame 100 and arranged along the front-back direction of the frame 100. A first slide block 282 is movably installed on the first slide rail 280. The second slide rail 290 is disposed on the first slide block 282 and arranged along the left-right direction of the frame 100. The first mounting seats 210 of the two groups of bending devices 200 in the first clamping assembly are both movably installed on the second slide rail 290. Thus, the first mounting seat 210 can be driven by the first slide block 282 to move in the front-back direction, and the first mounting seat 210 can be driven by the second slide block 360 to move in the left-right direction. Thereby, the specific position of the bending device 200 can be flexibly adjusted so that the bending device 200 can move to a position suitable for bending the edge strip 800, which is beneficial to improving the accuracy and stability of the bending process of the edge strip 800. Specifically, referring to Figure 8 , the first slide block 282 is slidably installed on the first slide rail 280 through a first screw-nut mechanism, and a first handwheel 281 is connected to the screw of the first screw-nut mechanism. The position of the bending device 200 in the front-back direction can be manually adjusted through the first handwheel 281. The first mounting seat 210 is also movably installed on the second slide rail 290 through a second screw-nut mechanism, and a second handwheel 291 is provided on the screw of the second screw-nut mechanism. The position of the bending device 200 in the left-right direction can be manually adjusted through the second handwheel 291.

[0070] It can be understood that, in some embodiments, the second bending assembly can also adopt the same structure as the first bending assembly, and the present invention does not make specific limitations thereto.

[0071] Referring to Figure 3 , Figure 4 and Figure 9 , in some embodiments, the edge bonder further includes a pushing mechanism 300. The pushing mechanism 300 includes a first moving seat 310, a pushing portion 320, and a fourth pushing device 330. The first moving seat 310 is movably installed on the frame 100 and is located below the workbench 110; the pushing portion 320 is installed on the first moving seat 310 and can extend upward to the upper side of the workbench 110. The pushing portion 320 is located between the first bearing seat 130 and the second bearing seat 140. A limiting groove 321 adapted to the edge strip 800 is formed on one side of the pushing portion 320 facing the first bearing seat 130; the fourth pushing device 330 is installed on the frame 100 and can drive the first moving seat 310 and drive the pushing portion 320 to reciprocate between the first bearing seat 130 and the second bearing seat 140. The pushing portion 320 can push the edge strip 800 to move close to the first bearing seat 130 and make the first edge-bending section 810 cover the first side edge 710.

[0072] By adopting the above structure, the hemming strip 800 located on the second bearing seat 140 can be pushed close to the first bearing seat 130, and the first hemming section 810 can be directly moved to the first side edge 710 covered by the plate 700, thereby facilitating the hemming of the first side edge 710. By providing a limiting groove 321 adapted to the hemming strip 800 on the side of the pushing portion 320 facing the first bearing seat 130, the hemming strip 800 can be limited during the pushing process to prevent the hemming strip 800 from shifting during the pushing process, thereby improving the accuracy and stability of the hemming and bending process of the hemming strip 800.

[0073] It is understandable that, referring to Figure 9 Since the edge strip 800 is in a long strip shape, in order to improve the stability of the edge strip 800 when being pushed, the number of the pusher parts 320 can be set to three, and the three pusher parts 320 are arranged in sequence along the left and right directions. Of course, the number of the pusher parts 320 can be one, two, four or more, in addition to three, and the present invention does not make a specific limitation on this.

[0074] Reference Figure 9 In some embodiments, the pushing mechanism 300 also includes a third slide rail 350 and a second slide seat 360. The third slide rail 350 is installed on the frame 100 and is located below the workbench 110, and the third slide rail 350 is arranged in the front-to-back direction. The second slide seat 360 is movably installed on the third slide rail 350. The fourth pushing device 330 can drive the second slide seat 360 to move along the third slide rail 350. The first moving seat 310 is installed on the second slide seat 360, and the second slide seat 360 is also equipped with a tenth pushing device 340 that is transmission-connected to the first moving seat 310. The tenth pushing device 340 can drive the first moving seat 310 to move in the up and down directions, thereby pushing the pushing part 320 to extend upward from the workbench 110 or move downward to below the workbench 110.

[0075] By adopting the above-mentioned structure, the pushing part 320 can be moved to the bottom of the workbench 110 before pushing the edging strip 800, so that the edging strip 800 can be conveniently placed or bent. When it is needed to be pushed, the pushing part 320 is moved forward to the front side of the edging strip 800 and moved upward to extend out of the workbench 110. Thereafter, the pushing part 320 is moved backward so that the edging strip 800 is embedded in the limiting groove 321. Finally, the edging strip 800 is pushed to the first supporting seat 130 and the first side edge 710 is edged.

[0076] Reference Figure 3 , Figure 4 as well as Figures 10 to 12In some embodiments, the hemming machine further includes two sets of pressing mechanisms 400, which are correspondingly disposed on opposite sides of the first bearing seat 130 and correspond one-to-one to the two second side edges 720. The pressing mechanism 400 includes a second mounting seat 410, a fifth pushing device 420, a slider 430, and a pressing portion 440. The second mounting seat 410 is mounted on the frame 100, and a first abutting portion 411 is provided on the side of the second mounting seat 410 facing the first bearing seat 130; the fifth pushing device 420 is mounted on the second mounting seat 410; the slider 430 is mounted on the output end of the fifth pushing device 420, and a second abutting portion 431 is provided on the side of the slider 430 facing the first bearing seat 130, and the horizontal height of the second abutting portion 431 is higher than the horizontal height of the first abutting portion 411; the upper end of the pressing portion 440 is rotatably mounted on the slider 430; when the fifth pushing device 420 drives the slider 430 to move in a direction away from the first bearing seat 130, and makes the second abutting portion 431 located on the side of the first abutting portion 411 away from the first bearing seat 130, the pressing portion 440 abuts against the first An abutment portion 411 is arranged obliquely from top to bottom along the direction close to the first supporting seat 130, the second abutment portion 431 and the pressing portion 440 are separated from each other, and the lower end of the pressing portion 440 is arranged at an interval with the workbench 110 to form a clearance space for the second edging section 820 to pass through; when the fifth pushing device 420 drives the slider 430 to move along the direction close to the first supporting seat 130, and makes the second abutment portion 431 located on the side of the first abutment portion 411 close to the first supporting seat 130, the pressing portion 440 can be separated from the first abutment portion 411 and rotate downward under the action of gravity until it abuts against the second abutment portion 431, and the fifth pushing device 420 can drive the pressing portion 440 to press the second edging section 820 against the corresponding second side edge 720.

[0077] In the above structure, the setting of the pressing mechanism 400 can make way for the movement of the second edging section 820 and the third edging section 830 when the second edging section 820 is bent, and can press the second edging section 820 when the second edging section 820 is bent to the second side edge 720 close to the plate 700, so as to stably press the second edging section 820 against the second side edge 720, so that the second side edge 720 can be stably inserted into the edging groove 850 of the second edging section 820, thereby improving the bonding strength between the plate 700 and the second edging section 820, and making the edging of the plate 700 more firm and stable.

[0078] Specifically, in the above structure, the pressing portion 440 is rotatably mounted on the slider 430, and the first abutting portion 411 is provided on the side of the second mounting seat 410 facing the first bearing seat 130, and the second abutting portion 431 is provided on the slider 430. Thus, when the second edge section 820 is bent, the slider 430 can be driven by the fifth pushing device 420 to move to the side where the second abutting portion 431 is located away from the first bearing seat 130, and the pressing portion 440 can abut against the first abutting portion 411. Separated from the second abutting portion 431, the pressing portion 440 is in a state of being inclined from top to bottom along a direction close to the first supporting seat 130, which is equivalent to the lower end of the pressing portion 440 being lifted upward, so that a clearance space can be formed between the pressing portion 440 and the workbench 110. At this time, the pressing mechanism 400 is in a clearance state, and the second edge segment 820 can pass through the clearance space when bending, thereby avoiding the pressing mechanism 400 from interfering with the bending movement of the second edge segment 820, so that the bending of the second edge segment 820 is smoother and more stable. After the second edging section 820 is bent and passes through the clearance space, the fifth pushing device 420 can push the slider 430 to move toward the first supporting seat 130, so that the second abutting portion 431 gradually moves to the side of the first abutting portion 411 close to the first supporting seat 130, and the pressing portion 440 can gradually separate from the first abutting portion 411 and rotate downward under the action of gravity until it abuts with the second abutting portion. At this time, the pressing mechanism 400 is in a pressing state, and the fifth pushing device 420 can push the abutting portion to press against the second edging section 820 through the slider 430, and the second abutting portion 431 can prevent the pressing portion 440 from continuing to rotate under the pressing action of the second edging section 820, so that the second edging section 820 can be stably pressed against the second side edge 720.

[0079] It can be understood that the fifth pushing device 420 can specifically adopt a cylinder, an electric push rod or other linear driving mechanism, and the present invention does not make any specific limitation on this.

[0080] Reference Figure 3 , Figure 4 as well as Figures 10 to 12 In some embodiments, the pressing mechanism 400 also includes a second movable seat 450 and a sixth pushing device 460. The second movable seat 450 is movably mounted on the frame 100. The second mounting seat 410 is mounted on the second movable seat 450 and suspended above the workbench 110, and the clearance space is partially located between the second mounting seat 410 and the workbench 110. The sixth pushing device 460 is mounted on the frame 100 and is transmission-connected to the second movable seat 450. The sixth pushing device 460 can drive the second movable seat 450 to move in the front and rear directions.

[0081] In the above structure, the second mounting seat 410 is suspended above the workbench 110, and the clearance space is partially located between the second mounting seat 410 and the workbench 110, thereby making way for the movement of the second edge-binding section 820 and the third edge-binding section 830. In addition, the pressing portion 440 is pushed to move in the front-to-back direction by the sixth pushing device 460, so that the position of the pressing portion 440 in the front-to-back direction can be flexibly adjusted, so that the pressing portion 440 can be pressed to the appropriate position of the second edge-binding section 820 as needed, thereby making the edge-binding of the panel 700 by the edge-binding strip 800 more accurate and stable.

[0082] It is understandable that the sixth pushing device 460 may specifically be a cylinder, an electric push rod or other linear driving mechanism, and the present invention does not make any specific limitation on this.

[0083] Reference Figure 3 , Figure 4 as well as Figure 13 and Figure 14 In some embodiments, the hemming machine further includes a pressing mechanism 500 , which includes a third mounting seat 510 , a pressure member 520 , a pressure head 530 , a pressing device 540 , a connecting plate 470 and a second limiting plate 550 . The third mounting seat 510 is mounted on the frame 100; the pressure member 520 is mounted on the frame 100 and is located at the rear side of the first bearing seat 130. When the plate 700 is placed on the first bearing seat 130, the third side 730 is located on the pressure member 520; the pressure head 530 is movably mounted on the third mounting seat 510 and is located above the pressure member 520. The lower end of the pressure head 530 is provided with a downwardly protruding pressing portion 531. The pressure head 530 and the pressing portion 531 are both flexible parts; the pressing device 540 is mounted on the third mounting seat 510 and is transmission-connected to the pressure head 530. The pressing device 540 can drive the pressure head 530 to move closer to or away from the pressure member 520 in the up and down direction; the connecting plate 470 is mounted between the two second mounting seats 410 and is located at the rear side of the first bearing seat 130. The upper surface of the connecting plate 470 is provided with an upwardly protruding first limit plate 4 71; The second limit plate 550 is movably installed on the frame 100 and is located at the rear side of the connecting plate 470. The frame 100 is also equipped with a seventh pushing device 560 that is transmission-connected to the second limit plate 550. The seventh pushing device 560 can drive the second limit plate 550 to move along the front-rear direction; wherein, the second limit plate 550 can move forward to the rear side of the pressure-bearing member 520, and the connecting plate 470 can follow the second movable seat 450 to move forward to the top of the pressure-bearing member 520 and be arranged at a distance from the second limit plate 550. When the pressing device 540 drives the pressure head 530 to move downward, the pressure head 530 can move between the first limit plate 471 and the second limit plate 550 and move downward close to or abut against the connecting plate 470, and the clamping portion 531 can move between the connecting plate 470 and the second limit portion and move downward close to the pressure-bearing member 520.

[0084] In the above structure, the setting of the top pressing mechanism 500 can extrude the third edge folding section 830 from top to bottom, so that the third side 730 of the plate member 700 can be clamped in the edge folding grooves 850 of the two third edge folding sections 830. Thus, the plate member 700 and the edge folding strip 800 can be positioned and pressed tightly, which is convenient for the subsequent conveying or welding of the plate member 700, and can prevent the plate member 700 and the edge folding strip 800 from being misaligned or separated during the subsequent conveying process, and further improve the edge folding stability of the edge folding strip 800 on each side of the plate member 700.

[0085] Specifically, since the plate member 700 is placed on the first bearing seat 130 and the third side 730 is located on the pressure bearing member 520, when the third edge folding section 830 covers the third side 730, it is also located on the pressure bearing member 520. Thus, it is convenient to press the third edge folding section 830 by the top pressing device. When pressing, the second mounting seat 410 can be pushed by the sixth pushing device 460 to drive the connecting plate 470 to move forward, so that the connecting plate 470 is located above the pressure bearing member 520 and close to the front side of the pressure bearing member 520, and the second limiting plate 550 is pushed forward to the rear side of the pressure bearing member 520 by the seventh pushing device 560, so that the connecting plate 470 and the second limiting plate 550 are arranged at intervals. At this time, the pressing head 530 is driven by the pressing device 540 to move downward between the first limiting plate 471 and the second limiting plate 550, so that the pressing head 530 can be limited, and the pressing part 531 of the pressing head 530 can move downward through the space between the connecting plate 470 and the second limiting plate 550 and accurately press on the third edge folding section 830. In this structure, the connecting plate 470 can also play a role in limiting the pressing head 530, preventing the pressing head 530 from moving downward excessively and causing damage to the third edge folding section 830 by pressing.

[0086] It can be understood that in the above structure, the pressing part 531 made of a flexible part can protect the third edge folding section 830, avoiding the pressing part 531 directly pressing downward rigidly on the third edge folding section 830 and causing damage to the third edge folding section 830 by pressing. In addition, the pressing head 530 made of a flexible part can protect the connecting plate 470, avoiding the pressing head 530 directly pressing downward rigidly on the connecting plate 470 and causing damage to the connecting plate 470 when the pressing head 530 is pressed downward excessively, thus being beneficial to extending the service life of the connecting plate 470. Among them, the pressing head 530 and the pressing part 531 can specifically adopt flexible structures such as rubber and silica gel. The present invention does not make specific limitations on this. The pressing head 530 and the pressing part 531 can adopt an integrally formed structure or a split installation structure. The present invention also does not make specific limitations on this.

[0087] It can be understood that in the above structure, the pressing device 540 can specifically adopt linear driving mechanisms such as hydraulic cylinders and air cylinders, and the present invention does not make specific limitations thereon. In addition, the seventh pushing device 560 can also specifically adopt linear driving mechanisms such as hydraulic cylinders, air cylinders, and electric push rods, and the present invention does not make specific limitations thereon.

[0088] Referring to Figure 15 , in some embodiments, the edge wrapping machine further includes a feeding mechanism 600. The feeding mechanism 600 includes a third moving seat 610, an eighth pushing device 620, a suction cup 630, and a ninth pushing device 640. The third moving seat 610 is movably installed on the frame 100 and is located above the workbench 110; the eighth pushing device 620 is installed on the frame 100 and is in transmission connection with the third moving seat 610. The eighth pushing device 620 can drive the third moving seat 610 to move closer to or away from the first bearing seat 130; the suction cup 630 is movably installed on the third moving seat 610 and can suck or release the plate member 700; the ninth pushing device 640 is installed on the third moving seat 610 and can drive the suction cup 630 to move in the up and down direction; when the suction cup 630 sucks the plate member 700 and moves above the first bearing seat 130, the ninth pushing device 640 can drive the third moving seat 610 and drive the suction cup 630 to move downward, and press and fix the plate member 700 on the first bearing seat 130 through the suction cup 630.

[0089] In the above structure, the feeding and discharging of the plate member 700 on the first bearing seat 130 can be realized through the feeding mechanism 600. During feeding, the suction cup 630 can directly press downward against the plate member 700 to fix the plate member 700, and during discharging, the plate member 700 can be directly sucked for discharging. There is no need to waste extra moving time of the suction cup 630 in the middle. It can not only fix the plate member 700, but also improve the discharging efficiency of the plate member 700.

[0090] It can be understood that the suction cup 630 can specifically adopt a vacuum suction cup 630, whereby the plate member 700 with a flat surface can be sucked, or the suction cup 630 can also adopt an electromagnetic suction cup 630, whereby a solid metal plate or a metal mesh plate can be sucked. For the specific type and structure of the suction cup 630, it can be selected and adjusted according to the actual situation, and the present invention does not make specific limitations thereon.

[0091] Referring to Figure 3 , Figure 4 and Figure 15, in some embodiments, a feeding table 660 and a blanking table 670 are further provided on the workbench 110. The feeding table 660 and the blanking table 670 are respectively arranged on both sides of the first bearing seat 130. A welding device for welding the edge strip 800 and the plate member 700 can be provided at the blanking table 670. A fourth slide rail 650 is provided above the workbench 110. The fourth slide rail 650 is arranged along the left-right direction of the frame 100 and spans above the feeding table 660, the first bearing seat 130, and the blanking table 670. The third moving seat 610 is movably installed on the fourth slide rail 650. Three suction cups 630 for sucking or releasing the plate member 700 are installed on the third moving seat 610. An eighth pushing device 620 is installed on the fourth slide rail 650 and can drive the third moving seat 610 to move in the left-right direction. Thus, the three suction cups 630 on the third moving seat 610 can synchronously suck the plate members 700 on the feeding table 660, the first bearing seat 130, and the blanking table 670, or can simultaneously release the plate members 700 they suck to the first bearing seat 130, the blanking table 670, and an external material receiving device for storing the processed plate members 700. Thereby, the conveying efficiency of the plate members 700 can be greatly improved, and further the working efficiency of the edge binding machine can be improved.

[0092] A specific embodiment of the edge binding machine of the present invention for bending the edge strip 800 and edge-binding the plate member 700 is provided below.

[0093] Refer to Figures 1 to 9, in some embodiments, two sets of bending devices 200 of the second bending assembly are correspondingly arranged on the left and right sides of the second carrier 140, and two sets of bending devices 200 of the first bending assembly are arranged close to the first carrier 130 and correspondingly distributed on the left and right sides of the first carrier 130. When hemming, first, the feeding mechanism 600 conveys and fixes the plate member 700 on the first carrier 130, so that each side of the plate member 700 protrudes from the first carrier 130. Place the hemming strip 800 on the second carrier 140. First, bend the two third hemming segments 830 through the two sets of bending devices 200 of the second bending assembly. After bending, push the hemming strip 800 towards the first carrier 130 through the pushing mechanism 300, and make the first hemming segment 810 cover the first side 710. Then, push the two second hemming segments 820 to bend and cover the corresponding second sides 720 through the two sets of bending devices 200 of the second bending assembly. At this time, the third hemming segment 830 can move along with the second hemming segment 820 and cover the third side 730 from the left and right sides of the plate member 700. Then, press the two second hemming segments 820 through the pressing mechanism 400, and adjust the positions of the connecting plate 470 and the second limiting plate 550. Finally, press the third hemming segment 830 downward through the constant pressure device, so that the third hemming segment 830 is clamped and fixed with the third side 730. Thus, the hemming process of the plate member 700 can be completed, and it is convenient to convey the plate member 700 with hemming completed to the blanking position or other positions later.
