DETAILED DESCRIPTION

[0027] The present invention provides an automatic plate positioning device. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the scope of protection of the present invention.

[0028] This embodiment takes the automatic sheet metal positioning device (rear sheet metal automatic positioning device) arranged at the rear of the automatic welding equipment as an example. The automatic sheet metal positioning device (front sheet metal automatic positioning device) arranged at the front and the automatic sheet metal positioning device (rear sheet metal automatic positioning device) arranged at the rear have the same structure and are symmetrically arranged, that is, the tooth plates 21 are arranged relative to each other.

[0029] See also Figure 1 , Figure 3-4The present invention provides an automatic plate positioning device, comprising an upper pressing clamp 1, a lower pressing clamp 2 arranged below the upper pressing clamp 1, and a clamping mechanism 3 arranged on the lower pressing clamp 2, wherein the clamping mechanism 3 is used to make the upper pressing clamp 1 and the lower pressing clamp 2 contact or separate; the automatic plate positioning device also includes a side-to-side mechanism 4, wherein the side-to-side mechanism 4 includes a driving motor 401, a top block 402, a screw 403, a bearing seat 404, a top material push rod 405, and a top material block 406; the drive motor 401 is driven by a drive motor 401. The output end is transmission connected to the screw 403, the push block 402 is arranged on the screw 403, the end of the screw 403 is connected to the bearing seat 404, the bearing seat 404 is arranged on the lower pressure clamp 2, the push rod 405 is connected to the side wall of the push block 402, and the end of the push rod 405 is connected to the push block 406, the push block 406 is used to push the sheet material between the upper pressure clamp 1 and the lower pressure clamp 2, and the lower pressure clamp 2 is provided with a side sensing component 6 for sensing the side of the sheet material.

[0030] In actual use, the rear sheet is transported from the rear of the rear sheet automatic positioning device to the front, and is transported to between the upper pressure clamp 1 and the lower pressure clamp 2. After the sheet reaches the corresponding position, the drive motor 401 is triggered to run, and the drive motor 401 drives the screw 403 to rotate, so that the top block 402 moves toward the direction of the bearing seat 404, thereby driving the top block 406 to move in the direction of the sheet through the top push rod 405. When the top block 406 contacts the side of the sheet, the drive motor 401 continues to run until the other side of the sheet contacts the side sensing component 6. The side sensing component 6 is electrically connected to the control mechanism, and the control mechanism transmits a stop signal to the drive motor 401, and then the drive motor 401 rotates in the opposite direction (i.e., resets), and then the clamping mechanism 3 runs to move the upper pressure clamp 1 downward until the sheet on the lower pressure clamp 2 is clamped, and then the cutting and welding mechanism cuts the edge of the rear sheet. The front plate is transported from the front to the rear of the front plate automatic positioning device. The front plate is clamped by the above operation so that the two plates positioned by the side are close to each other, and then the cutting and welding mechanism welds the position where the two plates abut.

[0031] By setting up a clamping mechanism 3, the upper pressure clamp 1 and the lower pressure clamp 2 can clamp the sheet material when they are in contact, and allow the sheet material to pass through when the upper pressure clamp 1 and the lower pressure clamp 2 are separated; by setting up a side-to-side mechanism 4, the top block 402 moves to drive the top material block 406 to move, and the sheet material is pushed to one side under the action of the top material block 406, so that the side edge of the sheet material is in contact with the side edge sensing component 6, thereby realizing the side positioning of the sheet material, thereby ensuring the welding quality of the two sheets.

[0032] See also Figure 1 and Figure 5Furthermore, the side sensing component 6 includes a first side positioning block 61, a second side positioning block 62 and a contact sensor 63; the first side positioning block 61 is arranged on the upper surface of the lower pressing clamp 2 away from the side-to-side mechanism 4, and the second side positioning block 62 is arranged on the lower surface of the upper pressing clamp 1. The first side positioning block 61 and the second side positioning block 62 are staggered, and the contact sensor 63 is arranged on the first side positioning block 61 for contacting or separating with the side of the sheet.

[0033] When the upper clamp 1 moves downward, the upper surface of the first side positioning block 61 contacts the lower surface of the upper clamp 1, and the lower surface of the second side positioning block 62 contacts the upper surface of the lower clamp 2, so that a certain gap is formed between the upper clamp 1 and the lower clamp 2, providing a space for the top material block 406 to be set between the upper clamp 1 and the lower clamp 2. The inner side walls of the first side positioning block 61 and the second side positioning block 62 are flush, which play the role of limiting and opposing edges, so that the side of the sheet material contacts them. In actual use, after the side of the sheet material contacts the first side positioning block 61, the contact sensor 63 is triggered, so that the contact sensor 63 changes from disconnection to connection, and then transmits the in-position signal to the control mechanism, and the control mechanism controls the drive motor 401 to stop rotating.

[0034] See also Figure 1 and Figure 2 Furthermore, a clamping sensing component 7 is provided between the upper pressure clamp 1 and the lower pressure clamp 2, and the clamping sensing component 7 includes a mounting plate 71 connected to the side wall of the lower pressure clamp 2, and the mounting plate 71 is provided with a waist-shaped hole 72 extending along its height direction, and three clamping sensors 73 are provided in the waist-shaped hole 72, and a sensing plate 74 is provided on the side wall of the upper pressure clamp 1, and the three clamping sensors 73 are respectively used to sense the sensing plate 74, and the three clamping sensors 73 are respectively electrically connected to the clamping mechanism 3 and the driving motor 401.

[0035] When the upper clamp 1 moves downward, it drives the sensing plate 74 to move downward, until the clamping sensor 73 in the middle senses the sensing plate 74, which is a clamping operation (half-open state). At this time, the distance between the upper clamp 1 and the lower clamp 2 becomes smaller, and then the side-to-side mechanism 4 operates to perform the side-to-side positioning operation of the sheet material. The above operation plays a certain limiting role on the uneven sheet material, preventing the top material block 406 from not acting on the sheet material, that is, in order to prevent the height of the top material block 406 from being set too high and affecting the clamping of the upper clamp 1 and the lower clamp 2, the height of the top material block 406 is set shorter, and it is difficult to ensure that the top material block 406 contacts the side of the sheet material in the fully open state. When the side-to-side mechanism 4 completes the side-to-side operation of the sheet, it resets, and then the clamping mechanism 3 operates to make the upper clamp 1 continue to move downward. This is the secondary clamping. At this time, the clamping sensor 73 located at the bottom senses the sensing plate 74, and the upper clamp 1 and the lower clamp 2 are in a completely closed state.

[0036] See also Figure 1 and Figure 5 Further, the lower surface of the upper clamp 1 and the upper surface of the lower clamp 2 are both provided with tooth plates 21, and the two tooth plates 21 are on the same vertical extension line. The upper surface of the lower clamp 2 is also provided with a support plate 22, and one or more support plates 23 are also provided between the tooth plates 21 and the support plates 22; one or more support plates 23 are equidistantly provided between the ejector block 406 and the side sensing assembly 6. The tooth plates 21 and the support plates 22 are provided to support the sheet material, so that there is a certain distance between the sheet material and the upper surface of the lower clamp 2, to provide a setting space for the ejector block 406 and to clamp the sheet material when the tooth plates 21 provided above and below are in contact. The support plate 23 is provided to support the middle part of the sheet material, to provide a support point for the downward pressure of the upper edge fixing mechanism 8, and to prevent the downward pressure of the upper edge fixing mechanism 8 from being too large, which affects the flatness of the sheet material.

[0037] See also Figure 4 Furthermore, a groove 4061 is provided on the side wall of the ejector block 406 away from the driving motor 401, and the side edge of the sheet is provided in the groove 4061. The sheet on the lower pressing clamp 2 is supported on the supporting plate 22 and the tooth plate 21. During the movement of the ejector block 406, the groove 4061 is used to increase the contact area between the ejector block 406 and the side edge of the sheet and to limit the sheet to a certain extent, thereby preventing the sheet from being displaced during the pushing process.

[0038] See also Figure 1 , Figure 5-Figure 7Furthermore, an upper edge fixing mechanism 8 is also provided on the upper surface of the upper pressing clamp 1, which includes an edge fixing drive member 81, a connecting plate 82, a positioning plate 83, a positioning guide rod 84 and an edge fixing block 85; the output end of the edge fixing drive member 81 is arranged downward, and passes through the connecting plate 82 and is connected to the upper surface of the upper pressing clamp 1, the positioning guide rod 84 passes through the upper and lower surfaces of the upper pressing clamp 1, and its upper end surface is connected to the lower surface of the connecting plate 82, and its lower end surface is connected to the upper surface of the positioning plate 83, and an edge fixing block 85 is provided on the front side wall of the positioning plate 83, and two or more tooth plates 21 are provided on the upper pressing clamp 1, and the edge fixing block 85 is arranged between adjacent tooth plates 21, and the front side wall of the edge fixing block 85 is in contact with or separated from the side edge of another sheet material.

[0039] The automatic welding equipment can perform splicing welding (i.e., horizontally move two sheets of equal thickness and thickness > 1.0mm, and then perform horizontal welding), and can also perform stacking welding (i.e., weld two sheets of equal thickness and thickness < 1.0mm or two sheets of unequal thickness and thickness < 1.0mm, with the thicker sheet stacked on top and the thinner sheet stacked on the bottom). When performing splicing welding, the two sheets are clamped by the front sheet automatic positioning device and the rear sheet automatic positioning device respectively, and then welded. The specific operation is the same as above and will not be repeated here.

[0040] Stacking welding is divided into front stacking (i.e. the front sheet 100 is stacked on top of the rear sheet 200) and rear stacking (i.e. the front sheet 100 is stacked on the bottom of the rear sheet 200). The front stack is taken as an example for description here. The actions before sheet welding are the same as splicing welding (i.e. including the alignment, positioning and cutting of the front sheet 100 and the rear sheet 200). After cutting, the two sheets are close to each other. Before the two sheets are matched, the automatic positioning device for the rear sheet is opened to a clamping state, and the auxiliary material positioning device arranged behind the automatic positioning device for the rear sheet is operated to clamp the rear sheet 200 to play a role in auxiliary positioning. The upper edge fixing mechanism 8 operates, and the output end of the edge fixing driving member 81 contracts, causing the connecting plate 82 to move downward, and the positioning plate 83 and the edge fixing block 85 are synchronously moved downward by the driving of the positioning guide rod 84, and the lower surface of the positioning plate 83 contacts the upper surface of the rear plate 200; then, the front part of the automatic positioning device for the rear plate is tilted downward at a certain angle by the swing mechanism arranged below the automatic positioning device for the rear plate, so as to be misaligned with the front plate 100; then, after the alignment is in place, the automatic positioning device for the front plate is opened to a clamping state, and the side-to-side mechanism 4 retreats, and the feeding device located in front of the automatic positioning device for the front plate feeds the front plate 100 until the side edge of the front plate 100 contacts the front side wall of the edge fixing block 85, and the setting of the edge fixing block 85 plays a role in aligning the front plate The moving stroke of the material 100 is limited, and then the side-to-side mechanism 4 aligns the two sheets at the same time, and then the rear sheet automatic positioning device clamps them for the second time. Since the tooth plates 21 are provided on both the upper pressure clamp 1 and the lower pressure clamp 2, the two sheets are clamped at the same time by the tooth plates 21, and then the upper edge fixing mechanism 8 is reset (that is, the upper surface of the positioning plate 83 contacts the lower surface of the upper pressure clamp 1), the swing mechanism is reset (even if the rear sheet automatic positioning device is horizontal again), the front sheet automatic positioning device clamps them for the second time (the side-to-side mechanism 4 in the front and rear sheet automatic positioning devices is reset), and then the auxiliary fixing device located behind the rear sheet automatic positioning device is pressed down (the feeding device is reset), and finally the cutting and welding mechanism is triggered to cut the gap between the teeth on the tooth plate 21 ( Figure 8 The M area in the figure is the weld seam) and the two sheets are welded by spot welding. The rear stacking method is basically the same as the front stacking steps, except that the front sheet automatic positioning device is tilted downward, and the rear sheet 200 is transported from the rear to the front to the top of the front sheet 100, and then the front sheet automatic positioning device clamps the two sheets.

[0041] Through the above arrangement, the automatic plate positioning device is suitable for both tailored welding and overlap welding, and is very practical.

[0042] See also Figure 5-Figure 7, further, the fixed edge driving member 81 is an oil cylinder; the connecting plate 82 is also provided with an emergency cylinder 86 with an output end facing downward, and the output end of the emergency cylinder 86 contacts or separates from the upper surface of the upper clamp 1. The oil cylinder has a strong load-bearing capacity. When the oil cylinder fails, the connecting plate 82 loses the support force of the oil cylinder, and the gravity will drive the positioning guide rod 84, the positioning plate 83, and the fixed edge block 85 to move downward, thereby affecting the passage of the sheet between the upper clamp 1 and the lower clamp 2. By setting the emergency cylinder 86, when the oil cylinder fails, the emergency cylinder 86 is started, and the output end of the emergency cylinder 86 is extended and contacts the upper surface of the upper clamp 1 through the action of the air source, and then the connecting plate 82 is lifted, thereby driving the positioning guide rod 84, the positioning plate 83 and the fixed edge block 85 to rise, so that the upper surface of the positioning plate 83 contacts the lower surface of the upper clamp 1, which will not hinder the passage of the sheet, so that the sheet can continue to be produced or the fixed edge driving member 81 can be repaired.

[0043] See also Figure 3 and Figure 4 Furthermore, an oil inlet pipeline 11 and an oil outlet pipeline 12 are provided on the side wall of the upper clamp 1, and a valve 13 is provided on each of the oil inlet pipeline 11 and the oil outlet pipeline 12; the oil cylinder is connected to the oil inlet pipeline 11 or the oil outlet pipeline 12. The oil inlet pipeline 11 is connected to the oil inlet end of the oil cylinder, and the oil outlet pipeline 12 is connected to the oil outlet end of the oil cylinder. The valve 13 is opened to discharge the hydraulic oil in the oil inlet pipeline 11 and the oil outlet pipeline 12, so as to facilitate the maintenance of the oil cylinder without affecting the passage of the sheet metal.

[0044] See also Figure 4 , further, the side-to-side mechanism 4 also includes a motor seat 407, a coupling 408, a push rod guide sleeve 409 and a connecting column 410; the drive motor 401 is arranged on the motor seat 407, the output end of the drive motor 401 is connected to one end of the coupling 408, and the other end of the coupling 408 is connected to the screw 403; the push rod guide sleeve 409 is arranged on the upper surface of the lower pressing clamp 2, and the ejecting push rod 405 passes through the left and right side walls of the push rod guide sleeve 409; one end of the connecting column 410 passes through the motor seat 407 and the ejecting block 402 in sequence, and the lower end surface of the other end is connected to the upper surface of the lower pressing clamp 2. By setting the push rod guide sleeve 409 and the connecting column 410, the stability of the motor seat 407 and the ejecting block 402 is improved, thereby improving the moving stability of the ejecting block 406.

[0045] See also Figure 1 and Figure 4Further, the clamping mechanism 3 includes a clamping drive seat 31, a hydraulic cylinder 32 with an output end facing upward, a guide column 33 and a guide column cover 34; the clamping drive seat 31 is connected to the lower surface of the lower clamp 2, the hydraulic cylinder 32 is arranged on the clamping drive seat 31, and its output end is connected to the lower surface of the guide column 33, the guide column 33 penetrates the upper and lower surfaces of the upper clamp 1 and the upper and lower surfaces of the lower clamp 2, and its upper part is connected to the guide column cover 34, and the lower surface of the guide column cover 34 abuts against the upper surface of the upper clamp 1. In actual use, the output end of the hydraulic cylinder 32 is extended to lift the guide column 33 and the upper clamp 1, so that the upper clamp 1 and the lower clamp 2 are separated; the output end of the hydraulic cylinder 32 is contracted to drive the guide column 33 and the upper clamp 1 to move downward, so that the upper clamp 1 and the lower clamp 2 are in contact, and the hydraulic cylinder 32 has a strong load-bearing capacity and good stability.

[0046] See also Figure 3 Furthermore, an oil inlet pipe 11 and an oil outlet pipe 12 are provided on the side wall of the lower clamp 2, and a valve 13 is provided on each of the oil inlet pipe 11 and the oil outlet pipe 12; the hydraulic cylinder 32 is connected to the oil inlet pipe 11 or the oil outlet pipe 12. Through the above arrangement, it is convenient to discharge the hydraulic oil in the hydraulic cylinder 32 through the pipe.

[0047] See also Figure 4 Furthermore, threaded holes are respectively provided at both ends of the upper clamp 1, and emergency screws 14 are threadedly connected in the threaded holes, and blind holes 24 corresponding to the positions of the threaded holes are respectively provided at both ends of the lower clamp 2. Similarly, when the hydraulic oil cylinder 32 fails, the hydraulic oil inside is discharged, and the emergency screw 14 is rotated to open or close the upper clamp 1, so that the sheet material can pass through, which is convenient for the continued production of the sheet material or the maintenance of the parts in the clamping mechanism 3.

[0048] In summary, the present invention provides a clamping mechanism 3 so that the upper pressing clamp 1 and the lower pressing clamp 2 can clamp the sheet material when they are in contact, and the sheet material can pass through when the upper pressing clamp 1 and the lower pressing clamp 2 are separated; the side-to-side mechanism 4 is provided so that the top block 402 moves and drives the top material block 406 to move, and the sheet material is pushed to one side under the action of the top material block 406, so that the side of the sheet material contacts the side sensing component 6, and the sheet material is positioned on the opposite side, thereby ensuring the welding quality of the two sheets.
