[0043] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0044] The present invention relates to a side plate positioning device, comprising a base 100, a bracket 200, a first pressing mechanism 300, a second pressing mechanism 400, and a third pressing mechanism 500.

[0045] In this embodiment, the positioning device processes the box bottom plate component 800, such as... Figure 7 As shown, the bottom plate component 800 of the box consists of a bottom plate 810 and side plates 820. The front and rear sides of the bottom plate 810 are bent upwards, and the bottom plate 810 is U-shaped. The two side plates 820 are located on the left and right sides of the bottom plate 810, respectively. The two side plates 820 are parallel to each other and must be perpendicular to the bottom surface and the front and rear sides of the bottom plate 810.

[0046] like Figure 1 and Figure 2As shown, the base 100 can be flat, and the support 200 is L-shaped, conforming to the bottom surface of the base plate 810. Specifically, the support 200 includes a straight rod 210 and a horizontal rod 220. The straight rod 210 is vertical, and the horizontal rod 220 is horizontal. The straight rod 210 and the horizontal rod 220 are perpendicular to each other. At least the supports 200 are installed parallel to each other on the base 100. In this embodiment, two supports 200 are installed on the left and right sides of the base 100, respectively. The horizontal rod 220 of the support 200 faces forward and backward, and the straight rod 210 is perpendicular to the base 100 and located towards the rear of the base 100. The supports 200 together form a storage space 201 for placing the base plate 810. The third pressing mechanism 500 includes a pusher 510 and a third drive mechanism 520. The pusher 510 is located in front of the storage space 201 and faces the straight rod portion 210 of the bracket 200. The third drive mechanism 520 can be a cylinder or a motor, etc. The third drive mechanism 520 drives the pusher 510 to move horizontally towards the storage space 201; that is, in this embodiment, the pusher 510 moves horizontally back and forth.

[0047] The first pressing mechanism 300 includes a pressing base 310 and a first driving mechanism 320, such as Figure 1 and Figure 3 As shown, the pressure seat 310 is located above the storage space 201. The first drive mechanism 320 can be a cylinder or a motor, etc., and drives the pressure seat 310 to move up and down. The pressure seat 310 is provided with a limiting bottom surface 311 and a first limiting side surface 312. The limiting bottom surface 311 is at the bottom of the pressure seat 310 and is a horizontal plane. The first limiting side surface 312 is located on the left and right sides of the pressure seat 310 and is perpendicular to the limiting bottom surface 311. In this embodiment, the first limiting side surface 312 is a straight plane and is parallel to the plane of the workpiece on the side plate 820.

[0048] like Figure 1 and Figure 4 As shown, two second pressing mechanisms 400 are located on the left and right sides of the storage space 201, respectively. Each second pressing mechanism 400 includes a pressing head 410 and a second driving mechanism 420. The second driving mechanism 420 can be a motor or a cylinder, etc. The second driving mechanism 420 drives the pressing head 410 to move towards the storage space 201; that is, in this embodiment, the pressing head 410 moves horizontally left and right. The pressing head 410 is provided with a second limiting side 411, which is spatially parallel to the first limiting side 312.

[0049] like Figure 8As shown, before welding, the base plate 810 and its two sides are separated. In actual operation, the base plate 810 is first placed in the storage space 201, with the rear side of the base plate 810 abutting against the front side of the straight rod 210 of the bracket 200. The third drive mechanism 520 drives the push head 510 to move, and the push head 510 abuts against the front side of the base plate 810. Together with the straight rod 210 of the bracket 200, the front and rear sides of the base plate 810 are positioned. Then, the first drive mechanism 320 drives the pressure seat 310 to descend. The limiting bottom surface 311 of the pressure seat 310 presses against the bottom upper side of the base plate 810. Together with the crossbar 220 of the bracket 200, the bottom of the base plate 810 is clamped and positioned. At this time, the first limiting sides 312 on the left and right sides of the pressure seat 310 are close to the left and right sides of the base plate 810, and the first limiting sides 312 are perpendicular to the bottom of the base plate 810. Two side plates 820 are manually placed sequentially on the left and right sides of the base plate 810. With each side plate 820 placed, the second drive mechanism 420 on the corresponding side drives the pressure head 410 to move. The side plate 820 on that side is clamped between the second limiting side 411 of the pressure head 410 and the first limiting side 312 of the pressure seat 310, thus positioning the side plate 820 on the left / right side of the base plate 810 and effectively ensuring that the side plate 820 is perpendicular to the base plate 810. The base plate 810 and side plates 820 are positioned using the bracket 200, the first pressing mechanism 300, the second pressing mechanism 400, and the third pressing mechanism 500. Then, the contact edges between the side plates 820 and the base plate 810 are electrically welded or segmentally welded manually or with an automatic welding gun. After welding is completed, the pressure head 410, push head 510, and pressure seat 310 are retracted, allowing the welded base plate 810 to be removed.

[0050] In some specific embodiments of the present invention, such as Figure 3 As shown, the pressure seat 310 is mainly composed of two positioning frames 313. In this embodiment, the positioning frame 313 can be triangular, as shown in the right-angled triangle shape, with a hollow center to ensure the structural strength of the positioning frame 313. The two positioning frames 313 are connected by connecting rods 314, and can be connected to the bottom of the two positioning frames 313 by multiple connecting rods 314. The bottom of both positioning frames 313 is provided with a limiting bottom surface 311, and the two positioning frames 313 are parallel to each other and of equal height. The left side of the positioning frame 313 on the left is the first limiting side surface 312, and the right side of the positioning frame 313 on the right is also the first limiting side surface 312. When the pressure seat 310 presses down onto the base plate 810 placed on the storage space 201, the limiting bottom surface 311 of the positioning brackets 313 on both sides presses onto the bottom upper surface of the base plate 810 and is close to the left and right edges of the base plate 810. Together with the bracket 200, it presses and positions the left and right sides of the base plate 810, reducing deformation at the edges of the left and right sides of the base plate 810, and ensuring the vertical positioning between the side plate 820 and the base plate 810.

[0051] Furthermore, a first slide rail 330 is installed on the base 100. The first slide rail 330 is installed vertically, that is, the first slide rail 330 is perpendicular to the base 100. The pressure seat 310 is slidably connected to the first slide rail 330 via a first slide block 340. In this embodiment, the upper parts of the two positioning frames 313 are connected to the first slide block 340. The first slide rail 330 and the first slide block 340 guide the lifting and lowering of the pressure seat 310, ensuring that the bottom surface 311 and the first limiting side surface 312 of the pressure seat 310 are spatially stable during the movement.

[0052] In some specific embodiments of the present invention, a first claw portion 211 is provided on the straight rod portion 210 of the bracket 200. The first claw portion 211 is located at the top of the straight rod portion 210 and is bent toward the storage space 201. In this embodiment, the first claw portion 211 is bent at 90°. When the base plate 810 is placed in the storage space 201, the top of the rear side of the base plate 810 abuts against the first claw portion 211. Before the pressure seat 310 presses down, the first claw portion 211 is used to initially position the base plate 810 in the vertical direction, which facilitates the adjustment of the position of the base plate 810 before the pressure seat 310 presses down.

[0053] In some specific embodiments of the present invention, the pressure head 410 is T-shaped. In this embodiment, as shown... Figure 4 As shown, the pressure head 410 can be composed of a horizontal bar 412 and a vertical plate 413, with the horizontal bar 412 located at the top of the vertical plate 413, forming a T-shape. When the pressure head 410 moves and abuts against the side plate 820, the horizontal bar 412 and the vertical plate 413 respectively position the side plate 820 in the horizontal and vertical directions. Combined with the triangular positioning frame 313, the side plate 820 is effectively clamped and positioned.

[0054] In some specific embodiments of the present invention, such as Figure 5 As shown, the pusher head 510 includes a second slide block 511 and push blocks 512. A second slide rail 530 is provided on the base 100, with the second slide rail 530 facing forward and backward. The second slide block 511 is slidably connected to the second slide rail 530, and guides the movement of the pusher head 510 through the second guide rail. Several push blocks 512 are installed on the second slide block 511. The top of the push block 512 is provided with a second claw portion 513, which is bent towards the storage space 201. In this embodiment, the second claw portion 513 is bent backward at a 90° angle. When the pusher head 510 moves, the rearward side of the push block 512 abuts against the front side of the base plate 810, and the second claw portion 513 abuts against the upper edge of the front side of the base plate 810, which can cooperate with the first claw portion 211 to limit the vertical movement of the front and rear sides of the base plate 810, preventing the front and rear sides of the base plate 810 from jumping.

[0055] In some embodiments of the present invention, such as Figure 1 and Figure 6 As shown, a limiting block 600 is also provided on the base 100, and several limiting blocks 600 are located on the left and right sides of the storage space 201. Each limiting block 600 has a horizontal loading surface 610 and a third limiting side 620. The horizontal loading surface 610 is located at the top of the limiting block 600 and is horizontal in space. The third limiting side 620 extends upward from the horizontal loading surface 610 and is parallel to the first limiting side 312, i.e., perpendicular to the horizontal loading surface 610. When the base plate 810 is placed in the storage space 201, the bottom surfaces on both sides of the base plate 810 rest on the horizontal loading surface 610, while the third limiting side 620 limits the left and right edges of the base plate 810.

[0056] This invention also relates to an automatic welding device, such as... Figure 8 and Figure 9 As shown, the automatic welding equipment utilizes the aforementioned side plate positioning device 700. The automatic welding equipment also includes a rotary table 710 and an automatic welding torch (not shown in the figure). The side plate positioning device 700 is mounted on the rotary table 710. Figure 8 As shown, the rotation axis of the rotary table 710 is oriented front-to-back. After the base plate 810 and side plate 820 are positioned, the rotary table 710 rotates around the rotation axis, and the side plate positioning device 700 rotates, causing one side plate 820 to face upwards. The automatic welding gun moves to weld the currently upward-facing side plate 820. Then, the rotary table 710 rotates again, and the other side plate 820 faces upwards, and the automatic welding gun moves to weld the currently upward-facing side plate 820. The rotation of the rotary table 710 is used in conjunction with the welding operation of the automatic welding gun. The movement of the automatic welding gun can be driven by a robotic arm.
