Description

Technical Field

[0001] The present invention relates to the technical field of plate crack detection devices, in particular to a novel surface crack detection device for producing energy-saving building panels. Background Art

[0002] As a new type of green building material, energy-saving building panels are widely used in modern buildings due to their excellent thermal insulation, sound insulation, light weight, and high strength. Common energy-saving panels include polystyrene (EPS) panels, rock wool panels, and polyurethane composite panels. These materials play an important role in reducing building energy consumption and improving sustainability. However, during production, transportation, installation, and long-term use, energy-saving panels are prone to surface or internal cracks due to factors such as mechanical stress, temperature changes, humidity erosion, or material aging. These defects not only affect the appearance, but may also reduce their thermal insulation performance and structural strength, and even pose safety hazards. Existing traditional panel crack detection devices are mainly achieved through manual visual inspection, ultrasound, and computer vision. However, these crack detection devices still have some problems, as follows:

[0003] Existing crack detection devices use computer vision or ultrasound. Such devices are highly dependent on the intelligence of the equipment system and the accuracy of the detection end. Such detection devices will be affected by these factors during use. The price of such detection components is usually very expensive and precise. It is very easy for high temperature or accidental collision to cause its accuracy to be greatly reduced or even scrapped, which greatly increases the use cost of the entire detection device. In addition, the existing detection devices also rely on computer image reconstruction to present, and the cracks of the plate cannot be displayed intuitively on the plate. As a result, the crack condition of the plate cannot be well distinguished after the plate is tested, which affects subsequent production and processing. For this reason, we propose a new surface crack detection device for the production of energy-saving building panels. Summary of the Invention

[0032] The technical solutions of the present invention will be described clearly and completely below in conjunction with the drawings in the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The surface crack detection device for the production of new building energy-saving panels involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-4, a new type of surface crack detection device for the production of energy-saving building panels, including a side plate 1, rollers 2 are movably installed on both sides of the inner side plate 1, and conveyor belts 3 are movably sleeved on the two rollers 2. One end of the roller 2 on one side is connected to a driving motor, and a transmission belt 4 is provided on the conveyor belt 3. A positioning plate 5 is fixedly installed at one end of the side plate 1, a vertical pole 6 is fixedly installed on the top middle part of the side plate 1, a transmission gear 7 is rotatably installed on one side of the vertical pole 6, a first transmission wheel 8 is fixedly installed on one side of the transmission gear 7, a transmission belt 9 is sleeved on the first transmission wheel 8, and a second transmission wheel 10 is sleeved on the transmission belt 9, and a driving roller 11 is fixedly installed on the side of the second transmission wheel 10, a support assembly 12 is provided at the middle part of the top of the side plate 1 through an extension rod, a pressing plate 13 is movably installed on the top of the support assembly 12, an external pigment storage device 14 is provided on one side of the support assembly 12, and a detection mark assembly 15 is provided inside the support assembly 12;

[0034] Compared with the prior art, the present application provides a positioning plate 5 at the feed end, which can eliminate the position deviation of the plate caused by vibration during the feeding process, ensure that the subsequent plate can be centered below the detection part for comprehensive crack detection, and ensure the accuracy of the detection. At the same time, an external pigment storage device 14 is provided, and the external pigment storage device 14 is used to continuously supply pigment to the detection mark component 15, so that when the detection mark component 15 moves down and contacts the crack of the plate, its bottom end marks the surface of the plate with pigment, and different color combinations are marked for cracks of different depths. In this way, after the detection of the plate is completed, the location of the crack and the depth of the crack can be intuitively seen according to the color of the surface mark, and the efficient production and processing of the plate is facilitated by visualizing the crack. At the same time, a movable detection needle is provided inside the plate body 121. 151 and the marking needle 152 utilize the rotation of the conveyor belt 3 to drive the transmission belt 4 to rotate, and then drive the transmission gear 7 to rotate, so that the rotational force of the transmission belt 4 is transmitted to the driving roller 11 to form the rotational driving force of the driving roller 11. The rotation of the driving roller 11 can make the pressure plate 13 move up and down periodically, so that the detection mark component 15 performs a periodic downward pressing action. The bottom end of the detection mark component 15 will be inserted into the part where the crack on the surface of the plate is encountered, so that the marking needle 152 contacts the surface of the plate under the extrusion of the rubber film 157, so that the pigment in the marking head set at the bottom end of the marking needle 152 will mark the surface of the plate, and cracks of different depths will drop different numbers and colors of marking needles 152, thereby forming a marking difference on the surface of the plate, thereby making the cracks on the surface of the plate visible, and improving the detection effect of the cracks on the plate.

[0035] See also Figure 1-3A novel surface crack detection device for producing energy-saving building panels includes a transmission belt 4, which is arranged on both sides of a conveyor belt 3. The transmission belt 4 is attached to both sides of the conveyor belt 3 by Velcro. The surface of the transmission belt 4 is rough, and the teeth on the transmission gear 7 are pointed and connected to the surface of the transmission belt 4 in an engaging manner.

[0036] In this embodiment, it should be noted that the rotation of the conveyor belt 3 can drive the transmission belt 4 to rotate, and the transmission belt 4 can drive the second transmission wheel 10 and the drive roller 11 to rotate through the transmission gear 7. In this way, the conveyor belt 3 can rotate to transport the plate while driving the upper drive roller 11 to rotate, and the pressure plate 13 can synchronously and continuously drive the detection mark assembly 15 to move downward, detect cracks on the surface of the plate and mark them, thereby ensuring the linkage of the entire detection device structure.

[0037] See also Figure 1-4 A novel surface crack detection device for producing energy-saving building panels includes two positioning plates 5, which are symmetrically arranged at the feed end of the energy-saving panel conveyor, and the opposite sides of the two positioning plates 5 are configured with a gradually decreasing structure.

[0038] In this embodiment, it should be noted that the gradual reduction structure of the two positioning plates 5 can ensure that the energy-saving board can be gradually transported to the center during the transportation process, avoiding the position deviation of the energy-saving board due to vibration during the transportation process, and ensuring the accuracy and reliability of the subsequent surface crack detection results of the board.

[0039] See also Figure 1-4 A novel surface crack detection device for producing energy-saving building panels includes a drive roller 11. The outer surface of the drive roller 11 is evenly arranged with convex teeth, and the convex teeth are located on the side of the rotation direction and have an arc structure. A convex strip is provided in the middle of the upper surface of the pressure plate 13, directly below the drive roller 11. The convex strip moves in correspondence with the convex teeth. The diameter of the transmission gear 7 is larger than the diameter of the first transmission wheel 8. The diameter of the first transmission wheel 8 is equal to the diameter of the second transmission wheel 10. The diameter of the second transmission wheel 10 is smaller than the outer diameter of the drive roller 11.

[0040] In this embodiment, it should be noted that by utilizing the diameter difference between the various components, the driving roller 11 can rotate at a linear speed greater than the transmission belt 4, so that the detection mark component 15 can move down more frequently to detect cracks during the movement of the plate, thereby ensuring the comprehensiveness of the crack detection on the plate surface.

[0041] See also Figure 1-10A novel surface crack detection device for producing energy-saving building panels includes a support assembly 12, which includes a plate body 121. The plate body 121 has a plurality of through-holes 122 evenly formed thereon, a branch pipe 123 fixedly mounted inside the plate body 121, a supply pipe 124 fixedly mounted at the bottom end of the branch pipe 123, and a support frame 125 fixedly mounted inside the plate body 121.

[0042] In this embodiment, it should be noted that a detection mark assembly 15 is movably installed in the through-hole 122, and the branch pipe 123 is sealedly connected to the external pigment storage device 14. The height at which the external pigment storage device 14 is arranged is lower than the height of the branch pipe 123 and lower than the height at which the internal structure of the detection mark assembly 15 moves to the top. The supply pipe 124 is connected to the branch pipe 123, and a self-sealing baffle is provided at the bottom end of the supply pipe 124. In this way, the setting of the branch pipe 123 can store a portion of pigment therein, and then the pigment therein is replenished during the up and down movement of the detection mark assembly 15 to ensure that there is sufficient pigment during subsequent use, thereby ensuring the reliability of the visualization of cracks on the plate surface.

[0043] See also Figure 4-12 A novel surface crack detection device for the production of energy-saving building panels includes a detection mark component 15, which includes a detection needle 151 and a marking needle 152. The detection needle 151 is sleeved with a first spring 153, and the marking needle 152 is sleeved with a second spring 154. A top plate 155 is fixedly installed on the top of the detection needle 151, and a through groove 156 is provided on the top plate 155. A rubber film 157 is fixedly installed inside the through groove 156. An entry groove is provided on one side of the marking needle 152, and a partition 158 is fixedly installed at the notch. The marking needle 152 is located at the entry groove and is embedded with an insert plate structure 159. A material guide hose 1510 is provided on the insert plate structure 159. A material collection chamber 1511 is fixedly installed on one end of the material guide hose 1510, and a vertical plate 1512 is fixedly installed on the upper part of the material collection chamber 1511.

[0044] In this embodiment, it should be noted that the bottom end of the detection needle 151 is a rounded structure, and the marking needle 152 is arranged in pairs on the side of each detection needle 151. The lower part of the marking needle 152 is hollow, and a sponge is provided at the bottom end. The upper part passes through the top of the plate body 121 and is located at the bottom end of the pressure plate 13. The height of the top of the detection needle 151 and the two marking needles 152 is stepped down, and the top plate 155 is arranged to fit the lower surface of the pressure plate 13. The position of the through groove 156 corresponds to the position of the marking needle 152 and the rubber film 157 is arranged at the bottom end of the through groove 156. The inserting plate structure 159 is arranged in an L-shaped structure, and the bottom end is located on the marking needle 152 and is relatively movable and inserted into the slot. The support frame 125 is supported at the turning point of the inserting plate structure 159, and the two sides of the aggregate chamber 1511 are extended The horizontal rod is fixedly connected to the surface of the marking needle 152. The size of the vertical plate 1512 is smaller than the size of the internal cavity of the collection chamber 1511 and can push open the sealing plate set at the bottom end of the supply pipe 124. In this way, the top plate 155 can be driven downward by pressing the pressure plate 13, so that the detection needle 151 moves down and fits the surface of the plate. When a crack is encountered, the bottom end of the detection needle 151 will be inserted into the crack, so that the top plate 155 continues to move downward and drives the two marking needles 152 to move down one by one. The downward movement process is adaptive to the depth of the crack, and after the bottom end of the corresponding marking needle 152 moves down and fits the surface of the plate, it can be marked next to the crack, thereby making the crack visible. During the up and down movement of the marking needle 152, the pigment inside the marking needle 152 can be automatically replenished to ensure the continuous use of the device.

[0045] See also Figure 10-11 A novel surface crack detection device for producing energy-saving building panels includes a plug-in structure 159, which includes an outer plug-in plate 1591. The outer plug-in plate 1591 has an inner cavity 1592 formed therein. A return trough 1593 is formed on the top of the outer plug-in plate 1591. A return plate 1594 is movably installed inside the return trough 1593.

[0046] In this embodiment, it should be noted that the outer plug-in plate 1591 is in an L-shaped structure, and the bottom end is movably inserted into the marking needle 152. The inner cavity 1592 passes through both ends of the horizontal portion of the top of the outer plug-in plate 1591. The outer plug-in plate 1591 is turned at one end and slides against the surface of the partition 158. The return trough 1593 is inclined downward near the top of the end where the partition 158 is located. A notch is provided at the bottom end of the partition 158. The return plate 1594 is vertically arranged inside the return trough 1593, and a rotating pin is provided at the top. In this way, the outer plug-in plate 1591 can be moved up and down by utilizing the up and down movement of the marking needle 152. When the inner cavity 1592 moves relative to the outer plate 1591, the pigment inside the inner cavity 1592 flows in and is replenished. When the marking needle 152 moves downward, the outer plate 1591 moves upward relative to the partition 158, thereby scraping the pigment leaked during the movement into the return groove 1593, and automatically turning the bottom end of the return plate 1594 slightly to open and return it to the inner cavity 1592. When the pigment inside the inner cavity 1592 flows toward the marking needle 152, the return plate 1594 restricts it in the reverse direction to prevent the pigment from leaking out.

[0047] Working principle: place the plate on the surface of the conveyor belt 3, drive the motor to drive the roller 2 to rotate, and then drive the conveyor belt 3 to rotate to transport the plate. The transmission belt 4 rotates at the same time, driving the transmission gear 7 to rotate. The transmission gear 7 drives the second transmission wheel 10 and the driving roller 11 to rotate through the rotation of the first transmission wheel 8 and the transmission of the transmission belt 9. The rotation of the driving roller 11 causes the pressure plate 13 to move up and down continuously, thereby compressing the top plate 155 below to move, so that the detection needle 151 moves down to fit the surface of the plate. When there is a crack on the surface of the plate, the detection needle The bottom end of 151 will be inserted into the crack, and the continuous downward movement of the top plate 155 will compress the marking needle 152 and move it down to fit the surface of the plate, thereby leaving a mark on the surface of the plate. The mark will be different for different crack depths. The downward movement of the marking needle 152 will cause the outer plug-in plate 1591 to move up relative to the partition 158, and the residual paint on the surface of the partition 158 will be scraped off to the return trough 1593 and returned to the inner cavity 1592. The reverse movement will enable the inner cavity 1592 to move to the notch at the bottom of the partition 158 to dock and replenish the paint, thereby ensuring the continuous operation of the device.

[0048] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
