[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0026] Reference Figures 1 to 3 As shown, a welding plate conveying device of this utility model includes: a support assembly including a support plate 1, the support plate 1 including a support side for supporting the plate, the support side having a support space; and a conveying assembly 2 including a driving mechanism and a clamping mechanism, the clamping mechanism being connected to the output end of the driving mechanism, the clamping mechanism including a first driving member 26, a first clamping member 27, and a second clamping member 28, the first clamping member 27 and the second clamping member 28 being connected to the output end of the first driving member 26, the edge of the support space being located between the clamping ends of the first clamping member 27 and the second clamping member 28, and the plane where the clamping end of the second clamping member 28 is located being coplanar with the plane where the support side is located.

[0027] This embodiment of a welding plate conveying device transports a plate from the outside to the support side of a support plate 1, with one end of the plate extending into the support space on the support side. A drive mechanism then moves a clamping mechanism until the edge of the plate is between the clamping ends of a first clamping member 27 and a second clamping member 28. A first drive member 26 then moves the first clamping member 27 and the second clamping member 28 closer together until they have clamped the plate. Finally, the drive mechanism moves the clamping mechanism to the welding position. By clamping the plate with the first clamping member 27 and the second clamping member 28, the plate's posture is prevented from changing during movement. The drive mechanism moves the clamping mechanism, allowing the plate to move along a fixed path, preventing path and position deviations during movement, thus improving the accuracy of plate conveying and welding.

[0028] Reference Figure 1 and Figure 2 As shown, the support assembly includes a support plate 1, which includes a support side for supporting the plate. In this embodiment, the support side is located on the top side of the support plate 1, and a support space for accommodating the plate is provided on the support side. The plate can move within the support space, thereby forming a conveying path for the plate. The support assembly also includes a support base 11, with the support plate 1 located at the bottom of the support base 11, and an installation space provided within the support base 11.

[0029] Reference Figure 2 and Figure 3As shown, the conveying assembly 2 includes a driving mechanism and a clamping mechanism, with the clamping mechanism connected to the output end of the driving mechanism. The clamping mechanism includes a first driving member 26, a first clamping member 27, and a second clamping member 28. The first driving member 26 is a clamping driving member, and both the first clamping member 27 and the second clamping member 28 are connected to the output end of the first driving member 26. The support plate 1 has a first opening 12, through which the first clamping member 27 passes. The first driving member 26 can drive the first clamping member 27 and the second clamping member 28 to move towards or away from each other, and both the first clamping member 27 and the second clamping member 28 move vertically, thereby enabling the first clamping member 27 and the second clamping member 28 to perform clamping or opening actions. The edge of the support space is located between the clamping ends of the first clamping member 27 and the second clamping member 28, and the plane containing the clamping end of the second clamping member 28 is coplanar with the plane containing the support side. When the plate is located in the support space of the support plate 1, the edge of the plate is located between the clamping ends of the first clamping member 27 and the second clamping member 28. The first driving member 26 can drive the first clamping member 27 and the second clamping member 28 to clamp the edge of the plate. When the first clamping member 27 and the second clamping member 28 are in a clamping state, the plane where the clamping end of the second clamping member 28 is located is coplanar with the plane where the support side of the support plate 1 is located, thereby avoiding damage to the plate after the first clamping member 27 and the second clamping member 28 clamp the plate.

[0030] The drive mechanism includes a second mounting plate 21, a fourth drive member 22, and a second transmission member 23. The conveying assembly 2 also includes a movable seat 25. The second mounting plate 21 is located within the mounting space of the support base 11 and is connected to the bottom side of the support plate 1 via a connecting column 24. A slide rail is provided on the second mounting plate 21, and the movable seat 25 is slidably connected to the second mounting plate 21 through the cooperation of a slider and the slide rail. A clamping mechanism is connected to the movable seat 25. The fourth drive member 22 is a rotary drive member connected to the bottom of the second mounting plate 21, and the output end of the fourth drive member 22 passes through the second mounting plate 21. Two synchronous pulleys are rotatably connected to the second mounting plate 21, and the second transmission member 23 can be considered as a synchronous belt. The second transmission component 23 is sleeved on the output end of the fourth drive component 22. Specifically, one of the synchronous pulleys is connected to the output end of the fourth drive component 22, and the second transmission component 23 is sleeved on two synchronous pulleys, so that the fourth drive component 22 can drive the second transmission component 23 to rotate. The movable seat 25 is connected to the second transmission component 23, so that the fourth drive component 22 can drive the movable seat 25 to move. After the clamping mechanism completes the clamping of the plate, the fourth drive component 22 drives the movable seat 25 to move, thereby moving the plate on the support plate 1. Preferably, multiple clamping mechanisms are connected to the movable seat 25, so that the conveying assembly 2 can convey the plate more stably.

[0031] The sheet material conveying device includes at least two conveying components 2 arranged opposite to each other. The support space is located between two clamping mechanisms arranged opposite to each other, so that the two clamping mechanisms can clamp the opposite side edges of the sheet material and move the sheet material together, making the sheet material more stable and the force more balanced during the movement, avoiding deformation or damage to the sheet material, and improving the accuracy of the sheet material conveying process.

[0032] Reference Figure 4 As shown, the welding plate conveying device also includes a first limiting component 6. The first limiting component 6 includes a first connecting frame 61 and a first rolling element 62. The first rolling element 62 is cylindrical. The first connecting frame 61 is connected to the support plate 1. The first rolling element 62 is rotatably connected to the first connecting frame 61. The rotation axis of the first rolling element 62 is perpendicular to the plane where the support side of the support plate 1 is located, and the side wall of the first rolling element 62 is located at the edge of the support space. When the conveying component 2 conveys the plate, the first rolling element 62 abuts against the edge of the plate, so that the first rolling element 62 rotates while the plate moves, guiding the movement of the plate and thus making the conveying accuracy of the plate higher.

[0033] The first limiting component 6 also includes a second connecting frame 63 and a second rolling element 64. The second rolling element 64 is cylindrical. The second connecting frame 63 is connected to the first connecting frame 61, and the second rolling element 64 is rotatably connected to the second connecting frame 63. The rotation axis of the second rolling element 64 is parallel to the plane of the support side, and the rotation axis of the second rolling element 64 is perpendicular to the moving path of the clamping mechanism. The support space is located between the second rolling element 64 and the support plate 1. When the conveying component 2 conveys the plate, the second rolling element 64 abuts against the top side of the plate, thereby clamping the plate between the second rolling element 64 and the support plate 1. The second rolling element 64 rotates while the plate moves, preventing the plate from warping or deforming, thus improving the conveying accuracy of the plate.

[0034] The welding plate conveying device includes at least two first limiting components 6 arranged opposite to each other. The first limiting components 6 are arranged along the moving path of the plate, and the support space is located between the two first rolling elements 62 arranged opposite to each other, so that the first rolling elements 62 can abut against the opposite side edges of the plate, thereby preventing the plate from shifting during movement. The first limiting components 6 also include a connecting plate 65 and an elastic element 66. The elastic element 66 can be regarded as a spring. The first connecting frame 61 is slidably connected to the support plate 1, the connecting plate 65 is connected to the support plate 1, and the elastic element 66 is connected between the connecting plate 65 and the first connecting frame 61. So that when there is a deviation in the size of the plate, the first rolling elements 62 can also guide the movement of the plate, and the pressure applied by the elastic element 66 can keep the plate in the middle position of the support space, while avoiding wear between the plate and the first rolling elements 62 due to the deviation in the size of the plate. Preferably, the welding plate conveying device includes at least four first limiting components 6, which are disposed at both ends of the first opening 12 along the moving path of the clamping mechanism, so that the first limiting components 6 can guide the moving path of the plate before the plate clamping mechanism clamps the plate.

[0035] Reference Figure 2 and Figure 5 As shown, the welding plate conveying device also includes a positioning component 5, which includes a first mounting plate 51, a second driving component 54, and a stop block 55. The first mounting plate 51 is located within the mounting space of the support base 11. The first mounting plate 51 is connected to a third connecting frame 52 and is connected to the bottom side of the support plate 1 through the third connecting frame 52. The second driving component 54 is connected to the first mounting plate 51, and the stop block 55 is connected to the output end of the second driving component 54. The second driving component 54 can drive the stop block 55 to rise and fall. The support plate 1 has a second opening 13, and the stop block 55 can extend into the support space. When the stop block 55 extends into the support space, it can block the plate conveyed by the conveying component 2, thereby positioning the plate and ensuring that the plate is accurately positioned at the welding position. The first mounting plate 51 is connected to a sensor 53 via a bracket. The sensor 53 is connected to a controller, and the detection end of the sensor 53 faces the second opening 13. The sensor 53 can detect whether there is a plate on the support plate 1 at the position corresponding to the second opening 13. Preferably, the first mounting plate 51 is connected to a plurality of second driving components 54, thereby enabling the plurality of stops 55 to position the plate and improve the positioning accuracy of the plate.

[0036] The positioning component 5 also includes a third driving member 58 and a first transmission member 57. The third driving member 58 can be considered as a handwheel, and its surface is provided with anti-slip texture. The third driving member 58 is located outside the installation space. The first transmission member 57 can be considered as a lead screw. The third connecting frame 52 is slidably connected to the support plate 1 through the cooperation of a slider and a slide rail, thereby enabling the first mounting plate 51 to move. The first transmission member 57 is connected to the output end of the third driving member 58, so that the third driving member 58 can drive the first transmission member 57 to rotate. The first mounting plate 51 is connected to an assembly block 56, which fits onto the movable nut of the first transmission member 57. The support plate 1 is connected to a fixed plate 59, and the first transmission member 57 passes through the fixed plate 59 and is rotatably connected to it. The fixed plate 59 can support the first transmission member 57. The third driving member 58 can drive the first mounting plate 51 to move, and the movement path of the first mounting plate 51 is parallel to the drive path of the drive mechanism. The adjustable position of the first mounting plate 51 allows for adjustment of the plate's positioning position, thereby improving the applicability of the positioning component 5.

[0037] Reference Figure 1 As shown, the sheet material conveying device also includes a sliding member 3, which can be regarded as a roller conveying mechanism. The sliding member 3 includes multiple rotatable third rolling members, which can be regarded as rollers. The sliding path of the sliding member 3 is parallel to the driving path. The sliding member 3 is located at both ends of the sheet material conveying path on the support member, so that the sheet material can be moved to the support plate 1 through the support and auxiliary conveying of the sliding member 3. The sliding member 3 can be used for the transition between other devices and the sheet material conveying device.

[0038] Reference Figure 6 and Figure 7 As shown, the slider 3 is connected to a second limiting component 4, which includes a connecting seat 41 and a fourth rolling element 42. The fourth rolling element 42 is rotatably connected to the connecting seat 41. The sliding path of the slider 3 is located between the fourth rolling element 42 and the third rolling element. The posture of the fourth rolling element 42 is the same as that of the second rolling element 64, and will not be described again. The sheet metal can be clamped between the fourth rolling element 42 and the third rolling element, thereby preventing deformation of the sheet metal and preventing it from detaching from the slider 3.

[0039] The second limiting component 4 also includes a movable mechanism, which can be considered a quick-clamping mechanism. Specifically, the movable mechanism includes a fourth connecting frame 46, a connecting block 43, a first connecting rod 44, and a second connecting rod 45. The fourth connecting frame 46 is connected to the edge of the sliding member 3. The fourth connecting frame 46 includes a first connecting part 461 and a second connecting part 462. The hinge position of the first connecting part 461 is at a higher height than the hinge position of the second connecting part 462, and a V-groove is provided between the first connecting part 461 and the second connecting part 462. The connecting block 43 includes a third connecting part 431 and a fourth connecting part 432. The angle between the third connecting part 431 and the fourth connecting part 432 is a right angle, and the length of the third connecting part 431 is greater than the length of the fourth connecting part 432. The connecting seat 41 is connected to the third connecting part 431. The end of the fourth connecting part 432 away from the third connecting part 431 is hinged to the first connecting part 461. The first connecting rod 44 includes a fifth connecting part 441 and a sixth connecting part 442. The angle between the fifth connecting part 441 and the sixth connecting part 442 is an obtuse angle, and the length of the fifth connecting part 441 is greater than the length of the sixth connecting part 442. The sixth connecting part 442 is away from the fifth connecting part 431. One end of 1 is hinged to the second connecting part 462, and the obtuse angle position of the fifth connecting part 441 and the sixth connecting part 442 is located on the side away from the connecting block 43; the second connecting rod 45 includes a seventh connecting part 451 and an eighth connecting part 452, the included angle between the seventh connecting part 451 and the eighth connecting part 452 is a right angle, and the length of the seventh connecting part 451 is greater than the length of the eighth connecting part 452. The end of the eighth connecting part 452 away from the seventh connecting part 451 can abut against the side wall of the V-groove approaching the first connecting part 461. The junction position of the seventh connecting part 451 and the eighth connecting part 452 is close to the first connecting part 461. The fifth connecting part 441 and the sixth connecting part 442 are hinged at the junction. The end of the seventh connecting part 451 away from the eighth connecting part 452 is hinged at the junction of the third connecting part 431 and the fourth connecting part 432. By pushing the fifth connecting part 441, the eighth connecting part 452 abuts against the side wall of the V-groove, so that the fourth rolling member 42 can abut against the plate located on the sliding member 3. By pulling the fifth connecting part 441, the eighth connecting part 452 is moved away from the side wall of the V-groove, so that the fourth rolling member 42 can move away from the third rolling member, so that the use of the fourth rolling member 42 is more flexible.

[0040] In use, the sheet metal moves on the sliding member 3 via an external pushing device until it reaches the support side of the support plate 1, allowing one end of the sheet metal to extend into the support space on the support side. Then, the drive mechanism drives the clamping mechanism to move until the edge of the sheet metal is between the clamping ends of the first clamping member 27 and the second clamping member 28. Further, the first drive member 26 drives the first clamping member 27 and the second clamping member 28 to move towards each other until the first clamping member 27 and the second clamping member 28 complete the clamping of the sheet metal. Further, the drive mechanism drives the clamping mechanism to move, causing the sheet metal to move towards the welding position. During the movement of the sheet metal, the first rolling member 62 abuts against and rolls against the edge of the sheet metal, and the second rolling member 64 abuts against and rolls against the top side of the sheet metal. When the sheet metal abuts against the stop block 55, the sheet metal is in the welding position. Finally, after the sheet metal is welded, the stop block 55 descends, and the sheet metal continues to move until it is detached from the support plate 1.

[0041] This utility model discloses a welding plate conveying device. The plate is clamped by a first clamping member 27 and a second clamping member 28, preventing changes in the plate's posture during movement. A drive mechanism moves the clamping mechanism, allowing the plate to move along a fixed path, preventing path and position deviations during movement and thus improving the conveying accuracy. This also enhances the welding precision of the plate. The first rolling member 62 guides the plate's movement, while the second rolling member 64 prevents warping and other deformations, further increasing conveying accuracy. The cooperation between the elastic member 66 and the first connecting frame 61 ensures the plate is positioned in the center of the support space, preventing wear between the plate and the first rolling member 62 due to dimensional deviations.

[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
