[0002] In the production process of panel products, in order to ensure the accuracy of processing and manufacturing, they are usually required to be aligned. The conventional operation is to place the panel between two parallel alignment plates, and then drive the two alignment plates to move horizontally to the middle position of the panel synchronously. The position of the panel between the two alignment plates is corrected by using the limitation of the two alignment plates to make it in a centered state.

[0003] Currently, the existing alignment mechanisms on the market mostly use synchronous belts to drive the alignment plates, but their structure is to place the motor in the middle of the mechanism, and a synchronous belt drives the alignment plates on both sides to move relative to each other; in this way, the alignment plates are easily deflected due to installation errors or uneven force. When centering, the panels transported on the roller line are subjected to uneven clamping force, resulting in edge cracks on the panels, a high panel defective rate, and sometimes the panel is damaged due to excessive extrusion due to excessive displacement of the alignment plate.

DETAILED DESCRIPTION

[0024] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0025] like Figure 1-3As shown, a positioning mechanism suitable for a panel includes a frame 1, on which two parallel centering components 4 are connected via a guide component 5, two synchronous belts 2 that can rotate synchronously and in the same direction are relatively arranged on the inner side of the frame 1, and the frame 1 is also provided with a driving component 9 for driving the two synchronous belts 2 to rotate; one of the centering components 4 is connected to the lower side of the synchronous belt 2 via a first connecting member 6, and the other centering component 4 is connected to the upper side of the synchronous belt 2 via a second connecting member 7.

[0026] The frame 1 adopts a rectangular structure, and two synchronous belts 2 are rotatably arranged on the inner side of the frame 1, and are uniformly driven by a driving component 9 to rotate synchronously and in the same direction; the synchronous belt 2 is a closed-loop structure, and its two ends are arc-shaped when working, and its upper and lower sides move in opposite directions when working. Based on this, the first connecting member 6 and the second connecting member 7 are used to fix the two centering components 4 to the lower and upper sides of the two synchronous belts 2 respectively, and under the action of the guide component 5, the two centering components 4 can move toward or away from each other in the horizontal direction. When the two move toward each other, the panel between the two can be centered. When the two move away from each other, the panel can be conveniently moved down to enter between the two.

[0027] The driving component 9 drives the two synchronous belts 2 to rotate in the same direction and synchronously. Under the action of the first connecting member 6 and the second connecting member 7, the two centering components 4 are horizontally moved close to or away from the center position of the frame 1, and the direction and accuracy of the movement of the centering component 4 are ensured by the guide component 5, which effectively alleviates the deflection problem of the alignment plate 41 and solves the problem of cracks on the edge of the panel due to uneven clamping force when the alignment mechanism centers the panel, thereby greatly improving the yield of panel production.

[0028] As mentioned above, the second connecting member 7 includes a second clamping plate 71 fixedly connected to the upper side of the synchronous belt 2, and a second connecting plate 72 connected to one of the centering components 4 is arranged on the second clamping plate 71; the first connecting member 6 includes a first clamping plate 61 fixedly connected to the lower side of the synchronous belt 2, and a first connecting plate 62 connected to another centering component 4 is arranged on the first clamping plate 61.

[0029] Specifically, the upper and lower sides of each synchronous belt 2 are fixedly connected to the two centering components 4 through the second connecting member 7 and the first connecting member 6 respectively. The first clamping plate 61 and the second clamping plate 71 have the same structure, and the first connecting plate 62 is longer than the second connecting plate 72; when the synchronous belt 2 moves, the first clamping plate 61 and the second clamping plate 71 move accordingly, and transmit power to the corresponding centering component 4 through the connecting plate, driving it to move along the guide component 5.

[0030] like Figure 1 , Figure 4-5As shown, when the directional displacement of the two centering components 4 is too large, the panel will be over-extruded, causing the panel to break and cause losses. To avoid the aforementioned problem, an overpressure component 8 for buffering the floating of the first connecting plate 62 can be provided on the first clamping plate 61.

[0031] The overpressure assembly 8 includes a base plate 81 fixedly mounted on the first clamping plate 61, two baffles 82 are arranged opposite to each other on the top of the base plate 81, a guide rod 83 is installed between the two baffles 82, a sliding block 84 is slidably sleeved on the guide rod 83, and the first connecting plate 62 is fixedly mounted on the sliding block 84.

[0032] When the centering assembly 4 is excessively displaced, its reaction force on the panel will act on the sliding block 84 through the first connecting plate 62. The sliding block 84 is forced to slide on the guide rod 83 along the side opposite to the movement direction of the centering assembly 4 to prevent the panel from being broken due to excessive force. In this process, the bottom plate 81, the baffle plate 82 and the guide rod 83 all rotate synchronously with one side of the synchronous belt 2.

[0033] Furthermore, a spring 85 is provided between the sliding block 84 and the baffle 82, and the spring 85 is sleeved on the guide rod 83. When no force is applied, the sliding block 84 can be fixed on the guide rod 83 by the spring 85 to prevent it from shaking at will. Only when the sliding block 84 is subjected to a thrust (i.e. when the centering assembly 4 moves excessively), the thrust overcomes the elastic force of the spring 85, and the sliding block 84 will slide, thereby offsetting the damage and harm caused by excessive displacement; and when the centering assembly 4 moves away from the center position of the frame 1, the force of the spring 85 can quickly reset the sliding block 84, so as to facilitate the next centering operation.

[0034] The use of the overpressure component 8 can effectively solve the problem of panel breakage caused by excessive movement of the centering component 4, that is, the excess movement of the centering component 4 is converted to the sliding block 84 through the guide rod 83, which plays a buffering role; this structure can prevent the centering component 4 from moving excessively, ensuring that the centering work is carried out stably; in addition, the overpressure component 8 can also be installed between the second clamping plate 71 and the second connecting plate 72.

[0035] like Figure 1-3 As shown, pulleys 3 are provided at both ends of the synchronous belt 2, wherein the pulley 3 at one end is rotatably connected to the frame 1 via a bracket 31, and the pulley 3 at the other end is connected to the frame 1 via a driving assembly 9.

[0036] As mentioned above, the pulley 3 connected to the frame 1 through the bracket 31 is a driven wheel, and the pulley connected to the frame 1 through the driving assembly 9 is a driving wheel; a rotating shaft is provided in the middle of the bracket 31, and the driven wheel can be installed on the rotating shaft to realize rotation.

[0037] Among them, the driving component 9 includes a motor 91 installed on the frame 1, and the output end of the motor 91 is connected to a transmission shaft 92. The transmission shaft 92 passes through two pulleys 3 located at the same end of the two synchronous belts 2 in sequence, and the transmission shaft 92 is connected to the frame 1 through a bearing seat 93.

[0038] The motor 91 is fixedly mounted on the side of the frame 1. There are at least two bearing seats 93, which are located on the inner sides of the two driving wheels and are used to support the transmission shaft 92. The transmission shaft 92 passes through the bearings inside the bearing seats 93; it also passes through the two driving wheels and drives them to rotate.

[0039] like Figure 1 As shown, the guide assembly 5 includes two slide rails 51 arranged opposite to each other, the slide rails 51 are fixedly installed on the top of the frame 1, and a slider 52 is slidably installed on each slide rail 51; the top of the slider 52 is fixedly connected to a fixed plate 10, one end of the fixed plate 10 is fixedly connected to the centering assembly 4, and the first connecting member 6 and the second connecting member 7 are both connected to the centering assembly 4 through the fixed plate 10.

[0040] The slide rail 51 is parallel to the moving direction of the upper and lower sides of the synchronous belt 2. The slider 52 is slidably installed on the slide rail 51 and is fixedly connected to the centering component 4 through the fixing plate 10. At the same time, the fixing plate 10 also plays the role of connecting the two centering components 4 with the first connecting member 6 and the second connecting member 7 respectively.

[0041] As mentioned above, the centering component 4 includes an alignment plate 41 perpendicular to the slide rail 51 , a plurality of alignment rods 42 are fixedly connected to the top of the alignment plate 41 , a roller 43 is rotatably connected to the top of each alignment rod 42 , and the alignment plate 41 is connected to the fixed plate 10 .

[0042] A plurality of alignment rods 42 are distributed in a straight line along the length direction of the alignment plate 41 . The alignment rods 42 are fixedly mounted on the alignment plate 41 . The two move synchronously, and the rollers 43 on the top of the alignment rods 42 facilitate the movement and centering of the panel.

[0043] Furthermore, an oblong hole 11 is provided on the alignment plate 41, and a mounting hole 12 is provided on the fixing plate 10, and one end of a fastener for connecting the alignment plate 41 and the fixing plate 10 passes through the oblong hole 11 and enters the mounting hole 12. The fastener is preferably a screw, one end of which passes through the oblong hole 11 and is screwed into the mounting hole 12, thereby achieving connection between the alignment plate 41 and the fixing plate 10; in addition, by adjusting the position of the mounting hole 12 relative to the oblong hole 11, the position adjustment of the alignment plate 41 in the centering direction can also be achieved.

[0044] As mentioned above, the length direction of the oblong hole 11 is parallel to the slide rail 51 , and a fine-tuning plate 13 is fixedly mounted on the fixing plate 10 , and an adjustment hole corresponding to the alignment plate 41 is opened on the fine-tuning plate 13 .

[0045] The adjustment hole of the fine-tuning plate 13 includes a tightening threaded hole and a connecting bolt hole. The alignment plate 41 is provided with a threaded connecting hole). By rotating the bolt in the tightening threaded hole, one end of the bolt will move linearly along the axial direction. When a certain part of the alignment plate 41 needs to be adjusted, the bolt is rotated so that one end of the bolt is against the side of the alignment plate 41 and is pushed forward with the rotation of the bolt, and then the connecting bolt is tightened to achieve the purpose of adjusting the mounting hole 12 relative to the oblong hole 11. Since the screw-in amount of the bolt is small, fine-tuning can be achieved to ensure the parallelism between the alignment plate 41 and the X-axis direction (the horizontal direction perpendicular to the slide rail 51); after the parallelism meets the requirements, the fasteners are tightened.

[0046] In addition, a plurality of position sensors 14 are provided on one side of the frame 1. The plurality of position sensors 14 are distributed in a straight line, and a sensing sheet 15 is installed on the corresponding fixed plate 10. As the fixed plate 10 moves, the sensing sheet 15 can pass through the grooves on the plurality of position sensors 14 in sequence. The grooves are equipped with infrared sensors. When the sensing sheet 15 passes through, its position can be sensed, thereby knowing the position of the centering component 4 relative to the frame 1.

[0047] Working principle:

[0048] The motor 91 drives the transmission shaft 92, and the transmission shaft 92 drives the two synchronous belts 2 to move synchronously and in the same direction; when the synchronous belt 2 moves, the first connecting member 6 and the second connecting member 7 drive the slider 52 to move along the slide rail 51, that is, drive the two alignment plates 41 to move to the middle position of the frame 1 at the same time, so that the alignment plates 41 clamp the product and align the product; when the alignment plates 41 are not parallel to the X-axis direction, the mechanism will cause uneven force on the edge of the panel when clamping the product, and at this time, the alignment plates 41 can be adjusted through the fine adjustment plate 13; in addition, the overpressure component 8 can be used to prevent the centering component 4 from moving excessively to ensure stable centering work.

[0049] To summarize, the motor 91 is placed on the same side of the two synchronous belts 2 and the power is transmitted by the transmission shaft 92, so that the alignment plate 41 is subjected to equal transmission force. The fine-tuning plate 13 can adjust the parallelism between the alignment plate 41 and the X-axis direction, which effectively solves the problem of deflection of the alignment plate 41 due to uneven tension during movement, reduces the problem of cracks on the edge of the panel, and effectively improves the yield of the panel.

[0050] The above is based on the ideal embodiment of the utility model.
