DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0027] In addition, the term "and / or" in this article is only a description of the association relationship between the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0028] Embodiment 1: like Figure 1 , Figure 2 and Figure 3As shown, the frame profile welding auxiliary device comprises: a base 1, a beam assembly 2, a rotating part 3, a driving mechanism 4 and a grabbing mechanism 5. The beam assembly 2 is installed on the base 1. A stacking guard plate 7 is installed on the top of the base 1. The number of stacking guard plates 7 is an even number and is divided into two groups. The two groups of stacking guard plates 7 are symmetrically arranged with each other. The space formed between the two groups of stacking guard plates 7 is the stacking placement space of the aluminum alloy frame profile 8. A plurality of aluminum alloy frame profiles 8 are stacked and placed continuously in the up and down directions to facilitate subsequent operations, such as Fig.13 As shown, the side walls of the aluminum alloy frame profile 8 are provided with a groove body 81, which is a standard part commonly found in the market. The base 1 is divided into two symmetrical parts by the beam assembly 2. The part with the stacking guard plate 7 is used as the stacking space, and the other part is used as the working space. The rotating part 3 is installed in the inner cavity of the base 1, and is used to drive the beam assembly 2 to rotate. The driving mechanism 4 is installed on the beam assembly 2, and the grabbing mechanism 5 is installed at the bottom of the driving mechanism 4. Through the action of the driving mechanism 4, the grabbing mechanism 5 can descend and grasp the uppermost aluminum alloy frame profile 8, and then the rotation of the beam assembly 2 is driven by the rotating part 3, so that the aluminum alloy frame profile 8 is automatically placed in the working space part on the base 1.

[0029] In addition, a welding device 9 is installed on the base 1. The welding device 9 is a FANUC ARC Mate 100iD welding robot, which has high precision and speed and can efficiently complete the welding work.

[0030] refer to Figure 4 The beam assembly 2 includes a column 21, a beam 22 and a counterweight 23. The column 21 is rotatably mounted on the upper surface of the base 1. The beam 22 and the counterweight 23 are both mounted on the top of the column 21, and the beam 22 and the counterweight 23 are symmetrically arranged relative to the column 21. The counterweight 23 is composed of a number of independent individuals, which can be selected according to actual needs. The weight of one side of the counterweight 23 is equal to the weight of one side of the beam 22, which can prevent the equipment from tipping over.

[0031] like Figure 4As shown, the rotating part 3 includes a first gear 31, a second gear 32 and a first motor 33. The first gear 31 and the second gear 32 are rotatably mounted in the inner cavity of the base 1, and the first gear 31 and the second gear 32 are meshed and connected. The second gear 32 is fixedly connected to the bottom end of the column 21. The first motor 33 is mounted on the upper surface of the base 1, and the output end of the first motor 33 passes through the outer wall of the base 1 and is connected to the first gear 31. Turning on the first motor 33 can drive the first gear 31 to rotate, and then drive the second gear 32 to drive the column to rotate, so that the position of the beam 22 changes. In this embodiment, the first motor 33 uses the NEMA17HS4401 model. This model of motor can accurately control the rotation angle and has good self-locking ability. It can not only accurately control the rotation angle of the first gear 31 but also ensure that the column will not rotate when the motor is turned off.

[0032] like Figure 2 and Figure 4 The driving mechanism 4 includes a lead screw 41, a moving block 42, a second motor 43, an extension plate 44, a first tooth 45, a third gear 46, a fourth gear 47, a stop plate 48, a lifting arm 49 and a second tooth 410. The lead screw 41 is mounted on the cross beam 22, and the moving block 42 is threadedly connected to the lead screw 41. The rotation of the lead screw 41 can drive the moving block 42 to move axially along the lead screw 41. At the same time, the cross section of the moving block 42 is an I-shaped setting, which can fit the cross beam 22 to ensure stability during movement and avoid self-rotation. The second motor 43 is mounted on the cross beam 22, and the output end of the second motor 43 is connected to one end of the lead screw 41. Turning on the second motor 43 can drive the lead screw 41 to rotate. The second motor 43 in this embodiment uses the NEMA 17HS4401 model, which can accurately control the angle of rotation and has good self-locking ability. After shutting down, it can ensure that the lead screw 41 is locked. At the same time, the lead screw 41 uses a lead screw with self-locking ability to ensure that the moving block 42 will not move actively. The extension plate 44 is mounted on the crossbeam 22. The number of first teeth 45 is several. Several first teeth 45 are equidistantly mounted on the upper surface of the extension plate 44. The third gear 46 is rotatably mounted on the side of the moving block 42 away from the lead screw 41. The third gear 46 is meshed with the first teeth 45. When the moving block 42 moves, the third gear 46 can be rotated. The fourth gear 47 is mounted on the third gear 46. The limit plate 48 is mounted on the moving block 42. The lifting arm 49 is mounted in the limit plate 48. The limit plate 48 can provide a limit for the lifting arm 49 to prevent the lifting arm 49 from tilting. The number of second teeth 410 is several. Several second teeth 410 are equidistantly mounted on the side of the lifting arm 49 opposite to the fourth gear 47. The fourth gear 47 is meshed with the second teeth 410. The fourth gear 47 rotates synchronously with the third gear 46, thereby driving the lifting arm 49 to move up and down.

[0033] During specific use, the second motor 43 is turned on to drive the lead screw 41 to rotate, thereby causing the moving block 42 to move. When the lead screw 41 rotates to move the moving block 42 away from the column 21, the third gear 46 drives the fourth gear 47 to rotate, thereby driving the lifting arm 49 to move downward. When the lead screw 41 rotates in the reverse direction, the moving block 42 can be made to approach the column 21, thereby driving the lifting arm 49 to move upward.

[0034] This solution can automatically drive the lifting arm 49 to move up and down while the moving block 42 is moving, so as to meet the grasping requirements of the aluminum alloy frame profiles 8 placed at different heights. Through the linkage of the mechanical structure, the accuracy of the equipment is improved. At the same time, the transfer of a single aluminum alloy frame profile 8 can be quickly realized, and it can be moved to the working space for welding. The equipment is compact and saves space.

[0035] As Figures 5 to 10 shown, the grasping mechanism 5 includes a housing 51, a lifting plate 52, a chute 53, opening and closing arms 54, a first slide rod 55, clamping arms 56, a first telescopic rod 57, a first spring 58, a moving piece 59, a card slot group 510, a stop piece assembly 511, a second slide rod 512, a second telescopic rod 513, a second spring 514, and a pushing arm 515. The housing 51 is a hollow structure. The lifting plate 52 is installed in the inner cavity of the housing 51. The pushing arm 515 is installed at the bottom of the lifting plate 52 and extends out of the bottom of the housing 51. The pushing arm 515 is made of a smooth material. In this embodiment, alumina ceramic or silicon nitride ceramic is selected. The friction between it and the aluminum alloy frame profile 8 is small, which is convenient for displacement on the surface of the aluminum alloy frame profile 8. The shape of the pushing arm 515 is a丄-shaped. The chute 53 is opened on the lifting plate 52 and is arranged in the horizontal direction. The number of the opening and closing arms 54 is two, which are respectively rotatably installed on the housing 51. The opening and closing arm 54 is composed of two rod bodies with an obtuse angle. The two opening and closing arms 54 are symmetrically arranged relative to the housing 51, and the opening and closing arm 54 penetrates the outer wall of the housing 51. The first slide rod 55 is installed on the opening and closing arm 54 and is installed in the chute 53. When the lifting plate 52 moves up and down, it can drive the opening and closing arm 54 to rotate, and at the same time, the first slide rod 55 can slide in the chute 53. The clamping arm 56 is installed on one side of the opening and closing arm 54 extending out of the housing 51. The clamping arm 56 corresponds to the groove body 81. As the opening and closing arm 54 rotates, the clamping arm 56 will be stuck into the groove body 81, and the aluminum alloy frame profile 8 can be grasped by pulling upward. The two ends of the first telescopic rod 57 are respectively installed on the top of the lifting plate 52 and the inner wall of the housing 51. The first spring 58 is sleeved on the first telescopic rod 57. When the lifting plate 52 is forced to move upward, it can compress the first telescopic rod 57 and the first spring 58. After the external force is removed, using the elastic force of the first spring 58, the first telescopic rod 57 can be restored and the lifting plate 52 can be reset.

[0036] There are two movable pieces 59, which are symmetrically mounted in the inner cavity of the housing 51. A slot group 510 is provided on the movable piece 59. The slot group 510 includes a first slot 5101 arranged horizontally and a second slot 5102 arranged obliquely. The first slot 5101 and the second slot 5102 are connected to each other. A baffle assembly 511 is mounted on the movable piece 59, and the baffle assembly 511 corresponds to the position of the slot group 510. The baffle assembly 511 includes a baffle 5111, a rotating shaft 5112 and a torsion spring 5113. The rotating shaft 5112 is mounted on the movable piece 59. The baffle 5111 is rotatably mounted on the rotating shaft 5112. The two ends of the torsion spring 5113 are respectively connected to the baffle 5111 and the rotating shaft 5112. When the baffle 5111 is forced to rotate, the torsion spring 5113 can be deformed. After the external force is removed, the baffle 5111 can be reset by the elastic force of the torsion spring 5113. The second sliding rod 512 is installed on the opening and closing arm 54 on the side opposite to the moving piece 59. The two ends of the second telescopic rod 513 are respectively installed on the moving piece 59 and the inner wall of the outer shell 51. The second spring 514 is sleeved on the second telescopic rod 513. When the two moving pieces 59 move laterally away from each other, the second telescopic rod 513 and the second spring 514 can be compressed. After the external force is removed, the elastic force of the second spring 514 can be used to restore the second telescopic rod 513 and reset the moving piece 59.

[0037] In actual use, the position of the shell 51 is made to correspond to the aluminum alloy frame profile 8, and the shell 51 moves downward. The pushing arm 515 contacts the surface of the aluminum alloy frame profile 8 to drive the lifting plate 52 to move upward, so that the two opening and closing arms 54 are relatively rotated by utilizing the cooperation of the first slide bar 55 and the slide groove 53, and the two clamping arms 56 approach each other until the clamping arms 56 are inserted into the groove body 81. At this time, the second slide bar 512 corresponds to the first slot 5101. Under the action of the second spring 514, the two moving plates 59 approach each other, and the second slide bar 512 is inserted into the first slot 5101. At the same time, the shell 51 stops descending, and the elastic force of the first spring 58 is utilized to make the lifting plate 52 have a tendency to move downward, so that the second slide bar 512 can be close to the bottom of the inner cavity of the first slot 5101. When it is necessary to release the aluminum alloy frame profile 8, the shell 51 continues to move downward for a distance, and the second sliding bar 512 moves and enters the second slot 5102. In this process, the blocking piece 5111 is toggled to rotate toward the inner cavity of the second slot 5102 and then reset. At the same time, the clamping arm 56 is completely inserted into the slot body 81; then the shell 51 rises, and the elastic force of the first spring 58 is used to reset the lifting plate 52. During this process, the second sliding bar 512 reversely toggles the blocking piece 5111, and the second slot 5102 and the blocking piece 5111 form an inclined channel. The second sliding bar 512 will not be partially blocked by the horizontal inner wall of the first slot 5101, and can thus smoothly leave the inner cavity of the slot group 510, and can drive the two moving pieces 59 away from each other to the initial position. At the same time, the two opening and closing arms 54 rotate in the opposite direction, so that the clamping arm 56 leaves the slot body 81, releasing the aluminum alloy frame profile 8, until the lifting plate 52 is reset and the release process is completed.

[0038] The device provided in this embodiment can automatically grab the aluminum alloy frame profile 8 and can also automatically release the aluminum alloy frame profile 8. The whole process is completely realized by a mechanical mechanism, and the stability is high. At the same time, in conjunction with the aforementioned beam frame assembly 2, the rotating part 3 and the driving mechanism 4, it can ensure that the aluminum alloy frame profile 8 is controlled by a rigid connector during the grabbing and transportation process, replacing the traditional steel wire lifting, ensuring that the aluminum alloy frame profile 8 is stable during the transportation and welding integration process, without the need to replace the positioning and clamping equipment midway, saving costs.

[0039] Embodiment 2: When the aluminum alloy frame profile 8 is clamped for welding, it is necessary to switch the horizontal aluminum alloy frame profile 8 to the vertical direction. In order to facilitate this requirement, this embodiment is proposed. The difference between this embodiment and the first embodiment is that an adjustment mechanism 6 is installed between the driving mechanism 4 and the grasping mechanism 5. Fig.11 and Fig.12As shown, the adjustment mechanism 6 includes a mounting seat 61, a rotating disk 62, a limiting groove 63, a limiting plate 64, a paddle assembly 65, a fifth gear 66, a sixth gear 67 and a third motor 68.
