[0002] UV board is a material widely used in various decoration and furniture fields. It is popular for its flat and smooth surface, rich color selection and high gloss or skin-feel effect. UV board is mainly used for customized door panels and some open cabinets of cabinets, and is also used for wall decoration, such as background walls, etc.

[0003] Considering that UV boards mainly play a decorative role in use, the process quality of their surface is crucial. Therefore, it is necessary to inspect the appearance quality of the surface decoration of the UV boards after production is completed.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0036] See also Figure 1 to Figure 11 In an embodiment of the present invention, a comprehensive detection device for the appearance quality of the surface decoration layer of a UV board includes: a frame structure, a coaxial wheel set, a locking assembly, a power assembly and an abutment rod 27.

[0037] A clamping assembly for clamping the UV board is rotatably installed on the frame structure, wherein the frame structure includes a base 1 and two brackets 2 arranged on the base 1. Furthermore, a visual inspection device 28 capable of moving along its width direction is arranged on the base 1. When the UV board is clamped, the UV board is in a horizontal state and remains parallel to the base 1. At this time, when the visual inspection device 28 is activated to perform appearance inspection, the distance between the UV board and the visual inspection device 28 can be ensured to be constant, thereby improving the inspection accuracy when the visual inspection device 28 inspects; the clamping assembly includes two symmetrically arranged groups of side panels 3, on which a connecting piece 12 rotatably connected to the bracket 2 is fixedly installed, and the two groups of side panels 3 are connected by two groups of first horizontal panels 4, and two groups of vertical grooves 303 are also symmetrically arranged on the side panels 3, and a second horizontal panel 5 is slidably installed in the vertical groove 303, and the first horizontal panel 4 cooperates with the second horizontal panel 5 to clamp the UV board; the clamping assembly also includes a staggered structure connecting the second horizontal panel 5, and the staggered structure The structure is used to drive the second cross plate 5 to move toward or away from the first cross plate 4. The staggered structure includes a vertical shaft 10 fixedly installed in the vertical groove 303, the vertical shaft 10 is slidably connected to the second cross plate 5, and a first spring 11 is sleeved on the vertical shaft 10, one end of the first spring 11 is connected to the side wall of the vertical groove 303, and the other end is connected to the second cross plate 5; a connecting rod 6 is fixedly installed at the end of the second cross plate 5, and a sliding connection part 7 is slidably installed on the connecting rod 6, the sliding connection part 7 is connected to the side plate 3 through a groove shaft kit, and a pulling rod 9 is provided on the sliding connection part 7, the groove shaft kit includes a first convex shaft 8 rotatably installed on the sliding connection part 7 and a guide groove provided on the side plate 3, and the first convex shaft 8 can roll in the guide groove; the guide groove includes a horizontal groove body 301 and an inclined groove body 302 provided on the side plate 3, when the first convex shaft 8 rolls in the inclined groove body 302, it can drive the second cross plate 5 to move toward or away from the first cross plate 4.

[0038] In detail, the first convex shaft 8 has two position states. Specifically, one is: the first convex shaft 8 is in the horizontal groove body 301, at this time, the first cross plate 4 and the second cross plate 5 are in a separated state, and the gap between the first cross plate 4 and the second cross plate 5 can make it easier for the operator to place the UV board between the first cross plate 4 and the second cross plate 5, and the first cross plate 4 supports the UV board. Since the movement directions of the horizontal groove body 301 and the second cross plate 5 are vertical, the second cross plate 5 has a certain position stability in this state, thereby avoiding the second cross plate 5 suddenly moving toward the first cross plate 4 during the placement of the UV board, causing the operator's hand to be pinched; the second is: the first convex shaft 8 is in the inclined groove body 302, at this time, the first spring 11 can drive the second cross plate 5 to move toward the first cross plate 4 by releasing its elasticity, and then clamp the UV board placed between the first cross plate 4 and the second cross plate 5, to ensure the stability of the UV board during the detection process and the deflection process of the side plate 3.

[0039] It should be noted that, when in use, the thickness of the UV board should be ensured to be greater than the minimum distance between the first horizontal plate 4 and the second horizontal plate 5. At this time, on the one hand, it can be ensured that the first horizontal plate 4 and the second horizontal plate 5 cooperate to clamp the UV board, and on the other hand, the first horizontal plate 4 and the second horizontal plate 5 cooperate to clamp the UV board within a certain thickness range, so as to achieve the ability to clamp UV boards of different thickness specifications to perform detection actions, and the thicker the UV board, the greater the distance between the first horizontal plate 4 and the second horizontal plate 5, so that the first spring 11 is compressed to a greater extent, and the first spring 11 can provide a greater downward pressure to the second horizontal plate 5, thereby realizing automatic matching of the clamping force and the thickness of the UV board.

[0040] When in use, by pushing and pulling the pulling rod 9, the sliding connection part 7 can be driven to move along the length direction of the connecting rod 6, thereby driving the first convex shaft 8 set on the sliding connection part 7 to move, so that the first convex shaft 8 can roll in the horizontal groove body 301 or the inclined groove body 302, thereby changing the distance between the connecting rod 6 and the second cross plate 5 relative to the first cross plate 4, thereby achieving the effect of releasing and clamping the UV board.

[0041] Through the above arrangement, the first horizontal plate 4 and the second horizontal plate 5 have two states: separation and mutual cooperation and clamping. When the two are in the separation state, the operator can more conveniently place the UV board between the first horizontal plate 4 and the second horizontal plate 5, and because the movement direction of the horizontal groove body 301 and the second horizontal plate 5 is vertical, the second horizontal plate 5 has a certain position stability in this state, thereby avoiding the second horizontal plate 5 suddenly moving toward the first horizontal plate 4 during the placement of the UV board, causing the operator's hand to be pinched. When the two are in the clamping state, the UV board can be stably clamped, thereby ensuring the stability of the UV board during the detection process and the deflection process of the side plate 3, and at the same time, the UV board within a certain thickness range can be clamped, and the clamping force can be automatically matched with the thickness of the UV board.

[0042] See also Figure 8 The coaxial wheel group is fixedly connected to the rotating shaft of the clamping assembly, and the coaxial wheel group includes a ratchet 13 and a limit member 14 coaxially fixedly connected to the rotating shaft of the connecting member 12, and two groups of limit grooves 1401 are circumferentially equidistantly arranged on the limit member 14, and the limit grooves 1401 cooperate with the locking assembly to axially lock the connecting member 12; the locking assembly is arranged on the bracket 2, and the locking assembly cooperates with the coaxial wheel group to axially lock the clamping assembly, and the locking assembly includes a guide member 16 fixedly mounted on the bracket 2, and a locking rod 15 is slidably mounted on the guide member 16, one end of the locking rod 15 is adapted to the limit groove 1401, and the other end of the locking rod 15 is connected to a second spring 17, and the end of the second spring 17 away from the locking rod 15 is connected to the guide member 16; the side of the locking rod 15 is provided with the second convex shaft 1501.

[0043] Among them, the length direction of the limiting groove 1401 is perpendicular to the length direction of the side panel 3. At this time, when the second protruding shaft 1501 of the locking rod 15 is inserted into the limiting groove 1401, it can ensure that the length direction of the side panel 3 is in a horizontal state, so that after the UV board is clamped, the UV board can be in a horizontal state, so that the visual inspection device 28 can maintain a consistent distance from the surface of the UV board when making a linear motion to detect the appearance quality of the UV board.

[0044] Furthermore, when the power component is in operation, it can abut against the second cam shaft 1501 and drive the second cam shaft 1501 to move upward and disengage from the limiting groove 1401. Then the driving component drives the ratchet 13 to rotate 180° and makes the locking rod 15 engage with the limiting groove 1401 again, so that the UV board can be locked again after being flipped 180°, so that the UV board can still maintain a horizontal state after being flipped 180°, and the other side of the UV board can be detected, thereby improving the detection accuracy.

[0045] See also Figure 1 , Figure 7 , Fig. 9 , the power assembly is installed on the bracket 2 and adapted to the second convex shaft 1501, the power assembly can drive the locking rod 15 to move and the ratchet 13 to rotate in turn, the power assembly includes an electric telescopic rod 18 fixedly installed on the bracket 2, and a connecting frame 19 is installed on the action end of the electric telescopic rod 18, and the end of the connecting frame 19 away from the electric telescopic rod 18 is connected to a ratchet plate 20 adapted to the ratchet 13, and a hook plate 2001 is provided on the ratchet plate 20, and the hook plate 2001 is slidably connected to a guide member 21 provided on the frame structure; the power assembly also includes a telescopic structure connected to the ratchet plate 20 The telescopic structure is adapted to the second convex shaft 1501, and the telescopic structure includes a hysteresis sleeve 22 fixedly connected to the ratchet plate 20, a telescopic shaft 25 is slidably installed in the hysteresis sleeve 22, and an inclined guiding surface 2501 is formed at one end of the telescopic shaft 25 away from the hysteresis sleeve 22, and the third convex shaft 26 is connected to the telescopic shaft 25 and passes through the hysteresis sleeve 22; a transverse shaft 24 slidably connected to the telescopic shaft 25 is also provided in the hysteresis sleeve 22, and a third spring 23 is sleeved on the transverse shaft 24, one end of the third spring 23 is connected to the inner wall of the hysteresis sleeve 22, and the other end is connected to the telescopic shaft 25.

[0046] In the initial state, the locking rod 15 is inserted into one of the limit grooves 1401, and the side plate 3 is in an axial locking state, so as to ensure that the distances between the various areas of the UV board and the visual inspection device 28 are consistent during the inspection. After the inspection of one side of the UV board is completed, the electric telescopic rod 18 will move to drive the ratchet plate 20 and the hysteresis sleeve 22 to move upward, and before the ratchet plate 20 is combined with the ratchet wheel 13, the telescopic shaft 25 in the hysteresis sleeve 22 will preferentially abut against the second convex shaft 1501. At this time, the second The convex shaft 1501 will drive the locking rod 15 to move upward, and the locking rod 15 will be separated from the limiting groove 1401, thereby realizing the axial unlocking of the limiting member 14, and then the ratchet plate 20 will be combined with the ratchet wheel 13, and drive the ratchet wheel 13 to rotate. At this time, the side plate 3 will drive the UV plate to deflect. After the UV plate deflects 180°, the locking rod 15 will be combined with the limiting groove 1401 again, and the limiting member 14 will be locked again, so that the side plate 3 and the UV plate can be axially locked, thereby improving the stability of the UV plate during the detection process and the accuracy of the detection results.

[0047] See also Figure 7 , Figure 9~Figure 11The abutment rod 27 is arranged on the frame structure, and the abutment rod 27 cooperates with the third cam shaft 26 arranged on the power assembly, so that the second cam shaft 1501 can be separated from the power assembly after the coaxial wheel group rotates a predetermined angle, wherein the third cam shaft 26 rolls and abuts against one side of the abutment rod 27, and the abutment rod 27 includes a first straight section 2701, an inclined section 2702 and a second straight section 2703, and the third cam shaft 26 can achieve horizontal movement according to the shape of the abutment rod 27 during the lifting process.

[0048] In the initial state, the telescopic shaft 25 is located at the lower part of the second convex shaft 1501 (see the attached Fig.10 ), and at the same time, the third cam 26 is in contact with the second straight section 2703, so that when the electric telescopic rod 18 drives the ratchet plate 20 to move upward, the telescopic shaft 25 can contact with the second cam 1501, and as the upward movement proceeds, the telescopic shaft 25 can drive the second cam 1501 to move upward until the locking rod 15 is separated from the limiting groove 1401, and when the third cam 26 moves to the end of the second straight section 2703, the ratchet plate 20 and the ratchet wheel 13 are combined, and the ratchet wheel 13 and the limiting member 14 are rotated, and at the same time, the third cam 26 will move in the inclined section 2702, so that the telescopic shaft 25 can move toward It moves toward the inside of the hysteresis sleeve 22 and gradually separates from the second convex shaft 1501. When the second convex shaft 1501 separates from the telescopic shaft 25, the locking rod 15 moves downward and abuts against the circumferential side wall of the limit member 14. Then the ratchet plate 20 continues to rise, so that when the ratchet 13 and the limit member 14 rotate 180°, the locking rod 15 is immediately inserted into another limit groove 1401 to achieve axial locking of the limit member 14, preventing the limit member 14 from excessively deflecting due to inertia, which makes it impossible for the locking rod 15 to smoothly engage with the limit groove 1401 when moving downward, thereby ensuring the accuracy of axial locking again after the UV plate is deflected 180°.

[0049] After the deflection action is completed, the electric telescopic rod 18 will drive the ratchet plate 20 to move downward, and the third convex shaft 26 will be reset to the second straight section 2703. At the same time, when the inclined guide surface 2501 on the telescopic shaft 25 abuts against the second convex shaft 1501 (see Fig.11 ), as the hysteresis sleeve 22 continues to drive the telescopic shaft 25 to move downward, the telescopic shaft 25 can move toward the inside of the hysteresis sleeve 22 under the cooperation of the second protruding shaft 1501 and the inclined guide surface 2501, until the telescopic shaft 25 moves to the lower part of the second protruding shaft 1501, so that the above steps can be repeated when the deflection action is performed next time.

[0050] Through the above arrangement, when the ratchet plate 20 moves upward, the telescopic shaft 25 can first be used to cooperate with the second convex shaft 1501 to axially unlock the limit member 14, and when the ratchet plate 20 cooperates with the ratchet wheel 13 to rotate the limit member 14 by a predetermined angle, the locking rod 15 can abut against the circumferential side surface of the limit member 14, so that after the limit member 14 rotates 180°, the locking rod 15 can quickly enter the other limit groove 1401, on the one hand, the flipped UV board can be axially locked, and on the other hand, the limit member 14 can be prevented from being excessively deflected due to inertia, so that the locking rod 15 cannot be smoothly combined with the limit groove 1401 when moving downward, thereby ensuring the accuracy of axial locking again after the UV board is deflected 180°.

[0051] It is worth noting that a damping sleeve is provided at the rotational connection between the connecting member 12 and the bracket 2 to prevent the side plate 3 from tilting after the locking rod 15 is separated from the limiting groove 1401, resulting in an incorrect angle during the deflection process.

[0052] As an embodiment of the present invention, a method for comprehensively detecting the appearance quality of the surface finishing layer of a UV board using the detection device is also proposed, comprising the following steps:

[0053] Step 1: Use the clamping assembly to clamp the UV board to be tested;

[0054] Step 2: Perform appearance quality inspection on one side of the UV board through a visual inspection device 28 installed on the frame structure;

[0055] Step 3: After one side of the UV board has completed the appearance quality inspection, the power assembly is activated, and the locking assembly and the coaxial wheel assembly are driven to operate in turn. When the locking assembly is activated, the axial locking of the clamping assembly can be released, and when the coaxial wheel assembly is activated, the clamping assembly can be driven to rotate;

[0056] Step 4: After the clamping assembly rotates a predetermined angle, the third convex shaft 26 cooperates with the abutment rod 27 to separate the power assembly from the locking assembly, and when the clamping assembly rotates 180°, the locking assembly cooperates with the coaxial wheel assembly again to axially lock the clamping assembly;

[0057] Step 5: Perform appearance quality inspection on the other side of the UV board, and remove the UV board after completion.
