Description

A comprehensive testing device for finished gypsum board products Technical Field

[0001] The present invention relates to the technical field of gypsum board detection, and in particular to a comprehensive detection device for finished gypsum board products. Background Art

[0002] During the production process of gypsum board, in order to ensure its production quality, its parameters such as thickness, length, diagonal, vertical edge, etc. need to be measured. Currently, the measurement method for gypsum board parameters is mostly manual inspection, using a vernier caliper to measure the thickness and length of the gypsum board, and then judging whether the gypsum board quality meets the quality requirements based on the manual measurement data.

[0003] Manual measurement usually has large errors, low accuracy, and low efficiency, and cannot adapt to the online production and detection of gypsum boards. To meet the needs of high-speed automated production, there are contactless electronic measurement methods in the existing technology, which measure the corresponding parameters when the gypsum board arrives. In order to detect the quality of the gypsum board surface, it is usually necessary to set up a camera to collect the gypsum board surface image in real time in a sampling manner, and analyze the gypsum board surface quality.

[0004] While the gypsum board inspection process is ongoing, the gypsum board is transported forward by rollers, which contact the bottom of the gypsum board to support the gypsum board during transportation. However, this transportation method causes the bottom end of the gypsum board to always face downward, making it impossible to collect image data of the lower surface of the gypsum board. Therefore, the automated transportation and inspection method cannot comprehensively and randomly inspect the entire gypsum board, resulting in the inability to obtain the quality of some board surfaces.

DETAILED DESCRIPTION

[0056] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0057] As shown in FIG1 and FIG3 , the present invention provides a comprehensive detection device for finished gypsum board products, which includes a detection roller 2 , a detection adjustment frame 3 , a limit assembly 4 and a detection element 5 .

[0058] The detection roller 2 consists of several roller sections 21. There is a height difference between at least some of the roller sections 21 along the transportation direction, so that the gypsum board 1 to be inspected is partially away from the surface of the roller section 21 in the area with the height difference, placed in the air and forms a temporary inspection area.

[0059] The detection and adjustment frame 3 is set near the area where there is a height difference on the detection roller 2. The detection and adjustment frame 3 has movable frames 31 arranged at the upper and lower parts. A mounting plate 32 is installed on the movable frame 31. The mounting plate 32 can move with the movable frame 31 to be parallel to the surface of the gypsum board 1. A detection element 5 is installed on the mounting plate 32, and the detection element 5 is facing the temporary detection area.

[0060] The limiting assembly 4 is arranged at the end of the movable frame 31 , and is used to form a support point at the end of the detection and adjustment frame 3 to support the part of the gypsum board 1 between the height difference area and the next roller section 21 .

[0061] In the present invention, the detection roller 2 is composed of several roller sections 21, and a height difference is formed between at least some of the roller sections 21 along the transportation direction, so that the gypsum board 1 to be inspected is partially away from the surface of the roller section 21 in the area where the height difference exists, placed in the air and forms a temporary detection area distributed on the upper and lower end surfaces of the gypsum board 1. During the inspection process, the bottom end surface of the gypsum board 1 is at least partially exposed to the outside, and the detection element 5 is collecting parameters of the temporary detection area. The gypsum board 1 can maintain a transportation state and can also be comprehensively measured during the transportation process.

[0062] In the present invention, the detection element 5 can be set as an infrared sensor, a laser detector, a camera, etc., for obtaining parameter data such as thickness, length and image.

[0063] In order to at least partially separate the gypsum board 1 from the surface of the roller section 21 during transportation, the present invention discloses two embodiments. The first embodiment is as follows:

[0064] As shown in FIG1 and FIG2 , the roller section 21 includes a plurality of first height rollers 211 and a second height roller 212 . The plurality of first height rollers 211 form a roller section 21 , and the plurality of second height rollers 212 form a roller section 21 . Each roller section 21 is horizontally arranged.

[0065] The height position of the first height roller 211 is higher than the height position of the second height roller 212 , and the roller section 21 formed by the second height roller 212 is arranged between the roller sections 21 formed by the first height roller 211 .

[0066] From the perspective of the transport direction, the gypsum board 1 passes through in sequence: the roller section 21 formed by the first height roller 211 , the roller section 21 formed by the second height roller 212 , and the roller section 21 formed by the first height roller 211 .

[0067] When passing through the roller section 21 formed by the second height roller 212, since both ends are supported by the first height roller 211, the bottom of the gypsum board 1 is away from the top of the second height roller 212. Therefore, the gypsum board 1 transported to the top of the second height roller 212 is in an empty state and can be inspected.

[0068] The detection element 5 is also arranged at the position corresponding to the second height roller 212. In order to avoid the second height roller 212 and the movable frame 31 and the mounting plate 32, the present invention also makes the following design. As shown in Figure 2, the length of the second height roller 212 is less than the length of the first height roller 211, the symmetry axis of the first height roller 211 coincides with the symmetry axis of the second height roller 212, and the sum of twice the length of the movable frame 31 and the length of the second height roller 212 is less than the length of the first height roller.

[0069] Correspondingly, the second height roller 212 is approximately the same height as the movable frame 31 located below when viewed from the front, and the second height roller 212 is only used to form a height difference. A corresponding limit plate may be provided, or only a gap may be provided in the second height roller 212 to enable gypsum board detection between the gaps. It is only necessary to ensure that the length of the gap is less than half the length of the gypsum board 1 to prevent the tail and the entire gypsum board 1 from falling into the gap.

[0070] The detection adjustment frame 3 in the present invention is of movable design. The movable frame 31 and the mounting plate 32 are movable structures. The mounting plate 32 moves to be parallel to the gypsum board 1, driving the detection element 5 to move to a temporary detection area facing the gypsum board 1.

[0071] The specific design is as follows, as shown in Figure 2, a mounting frame 33 is provided on the side of the movable frame 31, a sliding cavity 34 is provided in the mounting frame 33, the end of the movable frame 31 is slidably set in the sliding cavity 34, a driving motor 35 is provided in the mounting frame 33, and the output end of the driving motor 35 is connected to two sections of screw rods 36, the ends of the two sections of screw rods 36 are connected and the threads thereon run in opposite directions, and a thread groove cooperating with the screw rod 36 is provided in the movable frame 31.

[0072] During transportation of the gypsum board 1 , the gypsum board 1 is always located at the center between the two mounting plates 32 .

[0073] The driving motor 35 drives the screw 36 to rotate. Under the rotation of the screw 36, the upper movable frame 31 is driven to move downward and the lower movable frame 31 is driven to move upward. During this process, the mounting plate 32 is always parallel to the gypsum board 1 and gradually approaches the gypsum board 1. At the same time, the detection element 5 is driven to gradually approach the gypsum board 1 and is placed at a certain position outside the end face of the gypsum board 1 to collect parameter data.

[0074] After the data detection is completed, the driving motor 35 is driven again to reset the movable frame 31 and the mounting plate 32 to their initial positions.

[0075] In order to further realize the automatic detection of the gypsum board 1, the second embodiment is as follows.

[0076] As shown in Figures 3, 4 and 5, the roller section 21 includes a number of first transport rollers 213, a second transport roller 214 and a lifting roller 215 arranged between the first transport roller 213 and the second transport roller 214. The number of first transport rollers 231 form a first roller segment 216, the number of second transport rollers 214 form a third roller segment 217, and the number of lifting rollers 215 form a second roller segment 218.

[0077] The first roller segment 216 and the third roller segment 217 are both arranged horizontally, and the height of the third roller segment 217 is not lower than the height of the first roller segment 216 .

[0078] The first roller segment 216, the second roller segment 218 and the third roller segment 217 are initially on the same horizontal plane. When a gypsum board 1 passes by and needs to be inspected, the second roller segment 218 gradually rises to form an inclined roller state with a slope, and the third roller segment 217 also rises, but always remains in a horizontal state. At this time, there is a height difference between the second roller segment 218 and the third roller segment 217.

[0079] The second transport rollers 214 of the third roller segment 217 are coaxially connected with a drive shaft 219 , a second shaft seat 2110 is provided on the drive shaft 219 , and a lifting cylinder 2111 is provided at the bottom of the second shaft seat 2110 .

[0080] The lifting cylinder 2111 drives the second shaft seat 2110 to rise, and drives the second transport roller 214 to rise through the driving shaft 219, thereby driving the third roller segment 217 to rise as a whole.

[0081] When the gypsum board 1 is transported to the end of the second roller segment 218, the tail end of the gypsum board 1 gradually extends out of the second roller segment 218 and fails to enter the third roller segment 217 in time. The tail end of the gypsum board 1 extending out of the second roller segment 218 is idle in the air, and comprehensive parameter measurement can be performed.

[0082] In order to enable the second roller segment 216 to form an inclined slope, the present invention also makes the following design, as shown in Figures 3 and 6, a connecting shaft 2112 is coaxially arranged on the lifting roller 215, and a first shaft seat 2113 is arranged on the side of the connecting shaft 2112. A lifting shaft column 2114 is connected to the bottom of the first shaft seat 2113, and the connecting shaft 2112 is rotatably arranged on the first shaft seat 2113. A stud 2115 is arranged at the bottom of the lifting shaft column 2114, and the lifting shaft column 2114 is threadedly engaged with the stud 2115. A disc seat 2116 is arranged at the bottom of the stud 2115, and a bottom groove seat 2117 is arranged at the bottom of the disc seat 2116. In addition, as shown in Figure 9, at least a portion of the outer circumference of the disc seat 2116 is provided with meshing teeth 2118, and the portion of the outer circumference of the disc seat 2117 away from the meshing teeth 2118 is opposite to the portion of the outer circumference of the adjacent disc seat 2117 where the meshing teeth 2118 are provided.

[0083] The angle of rotation of the disc seat 2116 each time does not exceed 180 degrees, and the bottom of the disc seat 2116 at the end is connected to a connecting motor 2119.

[0084] The connecting motor 2119 drives the disc seat 2116 at the very end to rotate, thereby driving the stud 2115 to rotate. Under the rotation of the stud 2115, since the gypsum board 1 is already placed on the lifting roller 215 at this time, the lifting roller 215 cannot rotate, and correspondingly the lifting shaft column 2114 cannot rotate. Therefore, in this case, the rotation of the stud 2115 can drive the lifting shaft column 2114 to rise.

[0085] The lifting shaft column 2114 at the end gradually rises, and the lifting roller 215 at the bottom end gradually rises. During the rotation of the above-mentioned disc seat 2116, the meshing teeth 2118 rotate. After rotating clockwise for a small angle, the meshing teeth 2118 can drive the meshing teeth 2118 on the second disc seat 2116 (viewed from right to left) to rotate, thereby driving the stud 2115 to rotate, and driving the corresponding lifting shaft column 2114 to rise.

[0086] By analogy, assuming that at time t the first disc seat 2116 rotates and the lifting roller 215 rises, at time t+b the second disc seat 2116 rotates, at time t+2b the third disc seat 2116 rotates, ..., along the transportation direction, the rising height of the lifting roller 215 gradually increases and has a certain linear relationship, so that the second roller segment 218 presents a smooth upward trend.

[0087] In addition, in order to achieve the movement of the movable frame 31 during the forward movement of the gypsum board 1, the present invention further makes the following design: a friction sleeve 2120 is applied on the outer peripheral side of the lifting roller 215 at the end.

[0088] As shown in Figures 3, 7 and 8, a rotating motor 2121 is provided directly above the lifting roller 215, and the movable frame 31 located above is connected to the output end of the rotating motor 2121. The side of the first shaft seat 2113 located at the end is connected to the side of the side seat 2122, and a connecting gear 2123 is provided at the end of the connecting shaft 2112. A rotating shaft 2124 is provided through the side seat 2122, and a transmission gear 2125 is provided on the rotating shaft 2124. The connecting gear 2123 and the transmission gear 2125 are engaged.

[0089] In order to drive the gypsum board 1 forward, a driving source can be set on the other lifting rollers 215 except the end to drive them to rotate. The lifting roller 215 at the end is in a free rotation state. During the forward movement of the gypsum board 1, the friction sleeve 2120 is driven to rotate, thereby driving the lifting roller 215 to rotate. Correspondingly, the connecting shaft 2112 rotates, the connecting gear 2123 rotates, and drives the transmission gear 2125 to rotate, thereby driving the rotating shaft 2124 to rotate, thereby driving the movable frame 31 to rotate, and the mounting plate 32 follows to drive the detection element 5 to rotate.

[0090] In order to limit the rotation of the detection element 5, the present invention also makes the following design: a rotating buckle 2126 is provided at the end of the rotating shaft 2124, the rotating buckle 2126 and the rotating shaft 2124 are connected by a torsion spring, and the movable frame 31 located below is connected to the rotating buckle 2126.

[0091] As shown in Figure 8, an L-shaped limit block 2127 is provided on the outside of the side seat 2122, and the upper end of the L-shaped limit block 2127 fits with the outer peripheral side of the rotating shaft 2124. An upper limit block 2128 is provided above the movable frame 31 below, and the upper limit block 2128 corresponds to the upper side of the mounting plate 32.

[0092] In this embodiment, when the mounting plate 32 rotates to be parallel to the gypsum board 1, the mounting plate 32 just abuts against the upper limit block 2128. At this time, the mounting plate 32 can no longer rotate, but the gypsum board 1 continues to move forward, and the lifting roller 215 continues to rotate. In this case, the rotation of the rotating shaft 2124 can no longer drive the rotating buckle 2126 to rotate, that is, it will no longer drive the movable frame 31 to rotate. After that, the rotating shaft 2124 and the rotating buckle 2126 gradually move relative to each other, and the torsion spring is deformed.

[0093] When the gypsum board is detached from the lifting roller 215, under the action of the torsion spring, the lifting roller 215 rotates a certain angle counterclockwise, and the torsion spring resets. Then, under the action of gravity, the movable frame 31 can rotate clockwise to the initial position, and the L-shaped limit block 2127 limits it. At the same time, the movable frame 31 located above is reset, and the gypsum board 1 follows the mounting plate 32 to move to a horizontal state and is output to the second transport roller 214.

[0094] The first embodiment drives the detection when it is detected that the gypsum board 1 is in place. The second embodiment, based on the first embodiment, raises the second roller segment 218 after detecting that the gypsum board 1 is in place, so that the gypsum board 1 rises after passing through the second roller segment 218. Driven by the gypsum board 1, the movable frame 31 and the mounting plate 32 rotate, and the detection element 5 measures the parameter data thereof. Compared with the first embodiment, this design of measuring data only when the gypsum board 1 passes can avoid the misjudgment of whether the gypsum board 1 is in place. Only when the gypsum board 1 actually passes through the lifting roller 215 at the end can the detection element 5 be driven to move to face the gypsum board 1.

[0095] The main implementation process of the second embodiment is:

[0096] When the rear end of the gypsum board 1 is transported to contact the lifting roller 215 at the end, the motor 2119 is driven, and the lifting shaft 2114 rises from right to left, and the second roller segment 218 gradually tilts;

[0097] As shown in FIG4 , the lifting roller 215 drives the gypsum board 1 forward, and the gypsum board 1 moves on the lifting roller 215 at the end, driving the corresponding movable frame 31 and the mounting plate 32 to rotate;

[0098] Due to the limiting effect of the upper limit block 2128, when the mounting plate 32 rotates to be parallel to the gypsum board 1, the mounting plate 32 just abuts against the upper limit block 2128, and the mounting plate 32 cannot continue to rotate. The lifting roller 215 continues to rotate, and the rotating shaft 2124 and the rotating buckle 2126 gradually move relative to each other, causing the torsion spring to deform.

[0099] The detection element 5 collects data. When the gypsum board 1 moves away from the penultimate lifting roller 215, the gypsum board 1 no longer moves forward. Under the action of the torsion spring, the rotating shaft 2124 is subjected to a clockwise force, and the movable frame 31 is subjected to a counterclockwise force.

[0100] From an overall perspective, when the rear end of the gypsum board is on the mounting plate 32, the gravity it is subjected to must be greater than the counterclockwise resistance it is experiencing at this moment. The upper movable frame 31 rotates counterclockwise, while the lower movable frame 31 rotates clockwise. The gypsum board 1 gradually approaches a horizontal state (as shown in FIG5 ), and its rear end moves to the second transport roller 214 (during this process, the gypsum board 1 no longer moves in the inclined direction, so the lifting roller 215 can rotate freely. Correspondingly, the counterclockwise force of the movable frame 31 gradually dissipates as the gypsum board 1 separates from the lifting roller 215).

[0101] In addition, under the action of the torsion spring, the lifting roller 215 will also rotate counterclockwise by a certain angle, and the torsion spring will reset.

[0102] The present invention also designs a limit assembly 4, which mainly adopts the following preferred embodiments: the limit assembly 4 includes a support shaft seat 41 arranged at the end of the movable frame 31, and a support roller 42 arranged on the support shaft seat 41. The support roller 42 is rotatably installed on the support shaft seat 41 through a support shaft 43, and the support roller 42 is set to at least two.
