Description

Technical Field

[0001] This utility model relates to the field of furniture board testing technology, specifically a flatness testing device for furniture board production. Background Technology

[0002] Furniture boards are wood-based materials used to make furniture, primarily engineered wood products made from wood or other plant fibers. After processing, furniture boards need to be inspected for flatness to ensure the aesthetic appeal of the assembled furniture.

[0003] A search revealed a Chinese patent, publication number CN222258097U, which describes a furniture board flatness testing device: "It includes a base assembly with a reference component detachably placed on top; a board assembly is detachably placed on the upper surface of the reference component; a counterweight assembly for applying pressure to simulate a compressed state is detachably placed on the upper surface of the board assembly; the board assembly includes a furniture board body with rounded corners at its edges; and the counterweight assembly includes a counterweight block with a pressure simulation groove centrally located inside, used to apply pressure to the surface of the furniture board body to simulate a compressed state. This invention has the advantage of allowing the surface flatness of the furniture board body to be detected under pressure, thereby obtaining the surface quality of the furniture board."

[0004] Through a search of the aforementioned existing technologies, we found that the technology still has certain shortcomings in its use. When inspecting the flatness of the board, the board is placed on a reference component and inspected using a dial indicator. Although this method can achieve the purpose of inspection, the operation is relatively cumbersome, and only one side of the board can be inspected at a time. When it is necessary to inspect the other side of the board, the board needs to be flipped over, repositioned, and the inspection steps need to be repeated, which is inefficient and not conducive to the rapid inspection of the board.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 A flatness testing device for furniture board production includes a fixed base 1, a support frame 3 fixed to the top of the fixed base 1, multiple sets of testing components 4 evenly spaced on the left and right sides of the inner wall of the support frame 3, and multiple sets of conductive components 5 evenly spaced on the left and right sides of the outer wall of the support frame 3. Each testing component 4 includes a fixed rod 401 and a contact block 402. The fixed rod 401 movably passes through the support frame 3, and the contact block 402 is fixed to one end of the fixed rod 401. An LED bead 9 is installed at the other end of the fixed rod 401, and a conductive block 10 is provided on the top of the LED bead 9. Each conductive component 5 includes a fixed plate 501 fixed to the support frame 3. The bottom of the fixed plate 501 has a movable groove 502 for inserting the conductive block 10. Connecting block 1 503 and connecting block 2 504 are fixed on both sides of the inner top wall of the movable groove 502, respectively. Each set of testing components 4 corresponds to a set of conductive components 5, and multiple fixed plates 501 are located on top of multiple LED beads 9.

[0026] Please see Figure 1 and Figure 2 In this embodiment, the side of the contact block 402 away from the fixing rod 401 is designed as an arc structure, and multiple contact blocks 402 located on the same side of the inner wall of the support frame 3 are attached to each other.

[0027] Specifically, the side of the contact block 402 that contacts the furniture board body 13 is arc-shaped, which facilitates the sliding of the furniture board body 13 and allows it to pass between the contact blocks 402. The fact that multiple contact blocks 402 are attached together can reduce the gap and improve the detection effect on the furniture board body 13.

[0028] Please see Figure 1 , Figure 3 and Figure 5 In this embodiment, a conveying track 2 is also provided at the top center of the fixed base 1. The furniture board body 13 is rolled on the conveying track 2. The furniture board body 13 passes through the inside of the support frame 3, and the two sides of the furniture board body 13 are slidably attached to multiple abutment blocks 402 on both sides of the inner wall of the support frame 3. The conveying track 2 includes a frame and rollers rotatably connected to the inside of the frame. The top of the rollers protrudes from the frame.

[0029] Specifically, the rollers on the conveying track 2 can conveniently support and convey the bottom of the furniture board body 13, facilitating the movement of the furniture board body 13. In addition, the top of the inner wall of the support frame 3 is also equipped with rollers that limit the top of the furniture board body 13, so that the furniture board body 13 can pass through the inside of the support frame 3 stably, improving the detection effect. When the furniture board body 13 slides into contact with the contact block 402, the depressions or protrusions on the furniture board body 13 will act on the contact block 402, thereby using the movement of the contact block 402 for detection.

[0030] Please see Figure 2 , Figure 5 and Figure 6 In this embodiment, a movable cavity 11 is provided in the inner cavity of the support frame 3 at a position corresponding to each fixed rod 401. A fixed ring 403 fixedly sleeved on the fixed rod 401 is slidably connected in the movable cavity 11. A return spring 12 sleeved on the fixed rod 401 is fixed on one side of the fixed ring 403.

[0031] Specifically, when encountering a protruding point, the fixing rod 401 will be squeezed, and the fixing ring 403 will squeeze the return spring 12, thereby connecting the conductive block 10 with the first connecting block 503. When encountering a recessed point, the fixing rod 401 will move due to the return of the return spring 12, thereby connecting the conductive block 10 with the second connecting block 504.

[0032] Please see Figure 1 , Figure 4 and Figure 6 In this embodiment, batteries 6 are installed on both sides of the front of the support frame 3. Each battery 6 is electrically connected to a power transmission cable 7. The first connection block 503 and the second connection block 504 are electrically connected by a wire. Each second connection block 504 is connected to a connecting cable 8. The multiple connecting cables 8 located on the left side of the support frame 3 are electrically connected to the power transmission cables 7 on the battery 6 on the left side of the support frame 3. The multiple connecting cables 8 located on the right side of the support frame 3 are electrically connected to the power transmission cables 7 on the battery 6 on the right side of the support frame 3.

[0033] Specifically, the battery 6 can supply power to each LED bead 9 individually through the power transmission cable 7 and the connecting cable 8. When the furniture board body 13 is uneven, it can achieve the effect of instant conduction and lighting up the corresponding LED bead 9.

[0034] Please see Figure 5 and Figure 6In this embodiment, the fixing plate 501 is made of plastic, the top of the conductive block 10 is slidably attached to the inner top wall of the movable groove 502, the connecting block 1 503 and the connecting block 2 504 are far apart from each other, and the conductive block 10, the connecting block 1 503 and the connecting block 2 504 are all made of iron.

[0035] Specifically, the fixing plate 501 is made of plastic to achieve an insulating effect. When the conductive block 10 comes into contact with the first connecting block 503 and the second connecting block 504 respectively, it can conduct electricity and light up the corresponding LED beads 9.

[0036] When using:

[0037] Turn on the switch on the storage battery 6, place the furniture board body 13 whose flatness needs to be tested on the conveyor track 2, push the furniture board body 13 so that it moves on the conveyor track 2 and gradually enters the support frame 3, so that both sides of the furniture board body 13 contact the multiple abutment blocks 402 on both sides of the inner wall of the support frame 3. When it contacts the abutment blocks 402, it squeezes the abutment blocks 402, thereby squeezing the return spring 12 by the fixing rod 401 and the fixing ring 403, thereby driving the conductive block 10 to move and come to the middle of the top wall of the movable groove 502, that is, away from the first contact block 503 and the second contact block 504. Figure 6 As shown, as the furniture board body 13 passes between multiple abutting blocks 402, it can finally emerge from the back of the support frame 3. When both sides of the furniture board body 13 are flat, the multiple LED beads 9 will not light up.

[0038] When any side of the furniture board body 13 is uneven, if it is a dent, the reset spring 12 will push the fixing ring 403 and fixing rod 401 back to their original positions, thereby causing the conductive block 10 to move and contact the second connecting block 504. When the conductive block 10 contacts the second connecting block 504, it can conduct the LED bead 9 corresponding to the conductive block 10, thereby making the LED bead 9 light up. When the LED bead 9 lights up, it is convenient for the staff to observe it in a timely and intuitive manner from the front of the fixed base 1, which serves as a reminder to the staff that the side of the furniture board body 13 is uneven.

[0039] If any side of the furniture board body 13 protrudes, the protruding point of the furniture board body 13 will continue to press the corresponding abutment block 402. The abutment block 402 further presses the fixing rod 401, the fixing ring 403 and the return spring 12, thereby driving the conductive block 10 to move and contact the connecting block 503. When the conductive block 10 contacts the connecting block 503, it can conduct the LED lamp bead 9 corresponding to the conductive block 10, thereby making the LED lamp bead 9 light up.

[0040] After the furniture board body 13 that needs to be tested has been tested, the switch on the storage battery 6 can be turned off to stop the discharge;

[0041] In summary, this testing device can simultaneously test both sides of the furniture board body 13. When a dent or bulge appears on either side, the corresponding LED bead 9 on the support frame 3 will light up, thus providing a prompt to the testing personnel. The entire operation is simpler; the testing can be completed simply by pushing the furniture board body 13 to be tested. Moreover, the test results are more intuitive and easier for the testing personnel to judge.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
