Description

Technical Field

[0001] This utility model relates to the technical field of gypsum board production equipment, specifically to a diagonal detection device for finished gypsum board products. Background Technology

[0002] Gypsum board is a commonly used building material. During construction, the diagonal of the gypsum board is a very important indicator, which directly affects the subsequent decoration effect. Therefore, it is necessary to test the diagonal of the gypsum board during the production process.

[0003] In the prior art, the gypsum board diagonal detection device disclosed in CN116358423B can detect the diagonal of gypsum boards. This device clamps the gypsum board on a conveyor belt for detection. During the clamping process, the gypsum board is adsorbed through a combination of adsorption holes and an adsorption pump, suspending the gypsum board and preventing friction between the gypsum board and the conveyor belt during detection. However, in gypsum board production workshops, there is a lot of dust. Dust easily adheres to the vicinity of the adsorption holes of this gypsum board diagonal detection device, causing the adsorption function to fail. This results in the gypsum board falling off the device and continuing to rub against the conveyor belt, leading to a decrease in the yield rate due to wear and tear. Utility Model Content

[0058] See Figures 1 to 4 This embodiment provides a diagonal detection device for finished gypsum board 40, including a frame, a conveyor belt 20, two lifting arms 30 and a detection mechanism 50.

[0059] The conveyor belt 20 is mounted on the frame and connects with other conveying devices on the production line to receive the gypsum board 40. When the gypsum board 40 is on the conveyor belt 20, both ends of the gypsum board 40 extend beyond the conveyor belt 20 and are positioned above the lifting arms 30 on both sides.

[0060] Two lifting arms 30 are symmetrically arranged on both sides of the conveyor belt 20. One end of the lifting arm 30 is rotatably connected to the frame, and the other end of the lifting arm 30 can lift the plasterboard 40 on the conveyor belt 20 after rotating and rising. The two lifting arms 30 can lift the plasterboard 40 from both sides. A detection mechanism 50 is arranged on the lifting arm 30 and is used to perform diagonal detection on the plasterboard 40 on the lifting arm 30.

[0061] In this embodiment, the gypsum board 40 on the conveyor belt 20 is lifted by rotating one end of the lifting arm 30 around the other end, so that the gypsum board 40 is removed from the conveyor belt 20 during inspection, avoiding wear on the gypsum board 40 and thus improving the yield rate.

[0062] In one embodiment, the testing mechanism 50 includes two first testing components 51 and two second testing components 52.

[0063] Two first detection components 51 are located at the rotating ends of the two lifting arms 30, respectively. Two second detection components 52 are located at the ends of the two lifting arms 30 away from the first detection components 51, respectively. The two first detection components 51 and the two second detection components 52 can clamp the plasterboard 40 from its four corners, respectively.

[0064] In this embodiment, after one end of the lifting arm 30 is rotated, the plasterboard 40 is lifted, and the plasterboard 40 is clamped by the first detection component 51 and the second detection component 52 to prevent the plasterboard 40 from slipping off the lifting arm 30.

[0065] In one embodiment, the frame includes symmetrically arranged supports 10. The two supports 10 are located outside the two lifting arms 30, respectively. The inner walls of the two supports 10 can guide the ends of the plasterboard 40, making the plasterboard 40 more neatly arranged.

[0066] The lifting arm 30 includes a connecting part 31 and a supporting part 32.

[0067] The lower end of the connecting part 31 is rotatably connected to the inner wall of the support 10, and the lower end of the connecting part 31 is located below the conveyor belt 20. The upper end of the connecting part 31 can be rotated to be above the conveyor belt 20. One end of the support part 32 is connected to the upper end of the connecting part 31, and the other end of the support part 32 extends along the conveying direction of the conveyor belt 20. An electric push rod 33 is rotatably connected to the inner wall of the support 10. The output end of the electric push rod 33 is rotatably connected to the end of the support part 32 away from the connecting part 31. The lower end of the electric push rod 33 is rotatably connected to the support 10, and the upper end of the electric push rod 33 is rotatably connected to the end of the support part 32. The two support parts 32 are located on both sides of the transmission belt.

[0068] A light emitter (not shown) is also provided above the two supports 10. A light receiver (not shown) is provided below the two supports 10. The light emitter and the light receiver are connected to a PLC controller (not shown). The light emitted by the light emitter is received by the light receiver (and must avoid the area of ​​the conveyor belt 20). Once a plasterboard 40 is transported by the conveyor belt 20, the light emitted by the light emitter is blocked, and the PLC controller controls the electric push rod 33 to work, thereby realizing the rotation of the support 32.

[0069] In this embodiment, when the electric push rod 33 retracts, the support part 32 rotates downward and becomes lower than the conveyor belt 20. When the electric push rod 33 extends, the support part 32 rotates upward and lifts the plasterboard 40.

[0070] In one embodiment, the first detection component 51 includes a first clamping block 511 movably disposed on the support 32. The first clamping block 511 has a right-angle clamping opening. The right-angle clamping opening of the first clamping block 511 is used to clamp the corner of the plasterboard 40; the first clamping block 511 is movable close to the conveyor belt 20.

[0071] The second detection component 5 includes a second clamping block 521 movably disposed on the support 32; the second clamping block 521 has a right-angle clamping opening. The clamping opening of the second clamping block 521 is used to clamp the corner of the plasterboard 40. The second clamping block 521 is movable close to the conveyor belt 20. The second clamping block 521 is movable along the moving direction of the conveyor belt 20.

[0072] An infrared transmitter 512 is mounted on the first clamping block 511; an infrared receiver 522 is mounted on the second clamping block 521; the infrared transmitter 512 on the first clamping block 511 is opposite to the infrared receiver 522 on the opposite side of the second clamping block 521.

[0073] In this embodiment, after the conveyor belt 20 delivers the plasterboard 40 to the designated position, the support portions 32 on both sides rotate to support the plasterboard 40. At the same time, the first clamping blocks 511 on the support portions 32 on both sides move towards the conveyor belt 20. As the support portions 32 rotate further, the entire support portion 32 is placed at an angle. After the plasterboard 40 slides along the support portion 32, it abuts against the first clamping block 511. At this time, the two right-angled surfaces on the first clamping block 511 abut against the two corner surfaces of the plasterboard 40, thereby achieving clamping.

[0074] The second clamping block 521 moves down along the length of the support 32, and the two second clamping blocks 521 on both sides move closer to the conveyor belt 20, so that the two right-angled surfaces of the second clamping block 521 are in contact with the two corner surfaces of the plasterboard 40. At this time, the infrared light emitted by the infrared transmitter 512 on the first clamping block 511 is aligned with the infrared receiver 522 on the opposite second clamping block 521 along the diagonal of the plasterboard 40 and is exactly received by the infrared receiver 522, indicating that the diagonal detection is qualified. Conversely, if the infrared light emitted by the infrared transmitter 512 on the first clamping block 511 is misaligned with the infrared receiver 522 on the opposite second clamping block 521 along the diagonal of the plasterboard 40, it indicates that the diagonal detection is unqualified. The infrared transmitter 512 and the infrared receiver 522 are each electrically connected to the PLC controller. The PLC controller can display whether the diagonal detection of the plasterboard 40 is qualified through the display.

[0075] In one embodiment, the support portion 32 has a first mounting square hole 34 at one end near the connecting portion 31. The opening of the first mounting hole faces the conveyor belt 20. The center line of the first mounting hole is parallel to the rotation center line of the connecting portion 31.

[0076] The first detection component 51 also includes a first square rod 513, a first drive rod 515, and a first motor 516.

[0077] One end of the first square rod 513 slides through the corresponding first mounting square hole 34 and is connected to a vertically arranged first connecting rod 517. A first driving hole 514 is formed on the first square rod 513. The first driving rod 515 is threadedly connected to the first driving hole 514. The first motor 516 is connected to the support part 32, and the output end of the first motor 516 is connected to the first driving rod 515. The first connecting rod 517 is connected to the corresponding first clamping block 511. The first connecting rod 517 and the motor are located on opposite sides of the support part 32.

[0078] In this embodiment, the first directional rod can be driven by a motor to slide within the first mounting hole, thereby causing the first clamping block 511 to move closer to or further away from the conveyor belt 20. After the gypsum board 40 is inspected, when the support part 32 rotates downward, the first clamping block 511 moves away from the conveyor belt 20, and the gypsum board 40 is returned to the conveyor belt 20 and transported away.

[0079] In one embodiment, the second detection component 52 includes a slider 523, a second square rod 525, a second drive rod 527, and a second motor 528.

[0080] The slider 523 is slidably mounted on the support portion 32, and is located below the support portion 32. The slider 523 can slide along the length of the support portion 32, and a second mounting square hole 524 is provided on the slider 523. One end of the second square rod 525 slides through the corresponding second mounting square hole 524 and is connected to a vertically arranged second connecting rod 530. A second driving hole 526 is provided on the first square rod 513. The second driving rod 527 is threadedly connected to the second driving hole 526. The second motor 528 is connected to the support portion 32, and the output end of the second motor 528 is connected to the second driving rod 527. The second connecting rod 530 is connected to the corresponding second clamping block 521.

[0081] In this embodiment, the tilting state of the support 32 during rotation allows the slider 523 to slide closer to or away from the plasterboard 40 on the support 32. The second motor 528 drives the second drive rod 527 to rotate, which in turn moves the second square rod 525, thereby allowing the second clamping block 521 to move closer to or away from the conveyor belt 20, and thus closer to or away from the plasterboard 40. Both the first motor 516 and the second motor 528 are connected to a PLC controller, which can set the feed amount of the first square rod 513 and the second square rod 525 according to the different sizes of plasterboard 40. The sliding of the slider 523 allows the second clamping block 521 to automatically adapt to plasterboard 40 of different sizes.

[0082] In one embodiment, the support portion 32 is provided with a mounting groove 35 along its length direction;

[0083] The second detection component 52 also includes two guide rods 529 arranged side by side. The two ends of the guide rods 529 are respectively connected to the inner wall of the mounting groove 35; the slider 523 slides with the two guide rods 529 through two through holes.

[0084] In one embodiment, the support portion 32 is provided with a plurality of resistance-reducing protrusions 36. The resistance-reducing protrusions 36 are preferably cylindrical, and the sides of the cylindrical resistance-reducing protrusions 36 are used to support the plasterboard 40, allowing the plasterboard 40 to make line contact with it and slide smoothly on the support plate. Once the support portion 32 is tilted, the plasterboard 40 can smoothly move to the first clamping block 511 for clamping.

[0085] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of this invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.

[0086] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
