DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0038] Embodiment 1: A PCB board leveling device, such as Figure 1-Figure 4As shown, it comprises: a casing 1 with front and rear through openings, the casing 1 being hollow inside; an operator 2 fixedly mounted on the upper left front side of the casing 1, the operator 2 controlling the use of the leveling device; a guide rail 3 fixedly mounted in the through opening of the casing 1, the guide direction of the guide rail 3 being the front and rear direction; a holding plate 4 slidably mounted on the guide rail 3, the holding plate 4 comprising a support plate for supporting a PCB board 11 and a connecting seat slidably connected to the guide rail 3, the support plate being rotatably connected to the connecting seat, the PCB board 11 being placed on the holding plate 4, the connecting seat sliding back and forth on the guide rail 3 so that the holding plate 4 can cross the casing. Shell 1; a flattening member 5 fixedly mounted in the upper cavity of the shell 1, the flattening member 5 is composed of a mounting frame slidably connected to the shell 1 by a fixing plate, a spring fixedly connected between the fixing plate and the mounting frame, eight rollers rotatably connected to the bottom of the mounting frame, and a transmission belt wound on all the rollers. The flattening member 5 is started and closed by the operator 2; when the flattening member 5 is turned on, the rollers are controlled to rotate, and all the rollers are rotated through the transmission belt, and the spring presses down the mounting frame and its upper parts, so that the transmission belt of the flattening member 5 rolls and contacts with the PCB board 11, and at the same time, the rotating roller presses and flattens the PCB board 11; like Figure 5-Figure 7 As shown, it includes: a moving component 6 arranged in the casing 1, and the moving component 6 includes: a motor 61 fixedly installed in the lower cavity of the casing 1, and the operator 2 controls the motor 61 to start and stop; a moving handle 62 fixedly installed on the output end of the motor 61 using a connector; and a slide groove 63 fixedly installed at the bottom of the connecting seat of the holding plate 4, and the end of the moving handle 62 is slidably connected in the slide groove 63; when the motor 61 starts to rotate the moving handle 62, the moving handle 62 slides in the slide groove 63, and can control the holding plate 4 to reciprocate in the front and rear directions on the guide rail 3.

[0039] like Figure 8-Figure 11As shown, it includes: a reversing component 7 arranged in the casing 1, and the reversing component 7 includes: a ratchet bar 71 slidably installed at the rear opening of the casing 1 using a bracket, and the sliding direction is the left and right direction; a spring X72 mounted on the bracket where the ratchet bar 71 is located, the spring X72 is welded between the casing 1 and the ratchet bar 71, and the spring X72 enables the ratchet bar 71 to adaptively adjust its position; a ratchet gear 73 is fixedly installed under the support plate of the receiving plate 4, and passes through the receiving plate 4 under the connecting seat of the receiving plate 4, and the ratchet bar 71 can contact the ratchet gear 73; a fixed block 74 slidably connected to the bottom of the connecting seat of the receiving plate 4 using a mounting block; a spring Y75 mounted on the fixed block 74, the spring Y75 is welded between the fixed block 74 and the mounting block, and the spring Y75 acts to clamp the fixed block 74 in the ratchet teeth of the ratchet gear 73; when the receiving plate 4 and the ratchet gear 73 move backward, the bevel angle of the teeth of the ratchet bar 71 and the bevel angle of the teeth of the ratchet gear 73 When the locking cam 73 is in the unlocked position, the locking cam 73 is locked to the locking cam 74, thereby locking the locking cam 73 in the unlocked position and preventing the locking cam 73 from rotating.

[0040] Before using the leveling device, first place the PCB board 11 on the holding plate 4, control the leveling piece 5 and the motor 61 to start through the operator 2, and rotate the moving handle 62 to make the holding plate 4 move backward on the guide rail 3. During this process, the PCB board 11 on the holding plate 4 passes through the leveling piece 5 and is leveled in the front-to-back direction by the leveling piece 5. After completion, the PCB board 11 is now in the second half of the moving stroke, and the PCB board 11 will not contact the leveling piece 5. When the PCB board 11 continues to move backward, the ratchet gear 73 contacts the ratchet bar 71, and the ratchet gear 73 is rotated ninety degrees, which drives the holding plate 4 and the PCB board 11 thereon to rotate ninety degrees, realizing automatic reversing. After the reversing process is completed, the end of the moving handle 62 moves to the maximum of the movable range. At the rear end, the moving handle 62 will drive the containing plate 4 to move forward, the ratchet gear 73 is fixed by the fixing block 74, and the ratchet bar 71 is squeezed and slides to the left, that is, the PCB board 11 no longer rotates. At this time, the PCB board 11 will be moved to the bottom of the leveling member 5 in a state of being rotated 90 degrees from the initial state and leveled by the leveling member 5. Assuming that the PCB board 11 was leveled in its front and back direction when it was leveled for the first time, then this time the PCB board 11 is leveled in its left and right direction to ensure the leveling effect of the PCB board 11. Afterwards, the operator can decide whether to continue the next leveling process according to whether the PCB board 11 has completed the leveling process; after the completion, the PCB board 11 is removed and replaced with the next PCB board 11 that needs to be leveled.

[0041] Embodiment 2: Based on embodiment 1, Figure 12-14 As shown, it also includes a fixing component 8 for fixing the PCB board 11 on the holding plate 4; the fixing component 8 includes: a clamping frame 82 slidably mounted on the left and right sides of the support plate of the holding plate 4; a spring Z83 sleeved on the clamping frame 82, the spring Z83 is welded between the holding plate 4 and the clamping frame 82, the spring Z83 acts to make the clamping frame 82 close to the PCB board 11 on the holding plate 4, thereby fixing the PCB board 11 on the holding plate 4, and improving the position accuracy of the PCB board 11 during the leveling process.

[0042] like Figure 12-14 As shown, the fixing assembly 8 also includes: a column gear 84 rotatably mounted in the support plate of the holding plate 4; a synchronization rack 85 fixedly mounted on two clamping frames 82, the teeth of the two synchronization racks 85 are in opposite directions, and the two synchronization racks 85 are both meshed with the column gear 84, so the movement directions of the two synchronization racks 85 are opposite. When the clamping frame 82 is used, when a single clamping frame 82 is moved, the two synchronization racks 85 can be moved synchronously but in opposite directions through the meshing action of the column gear 84. Therefore, when the clamping frame 82 is used to clamp and fix the PCB board 11 or to release the clamping frame 82 from fixing the PCB board 11, only a single clamping frame 82 can be operated, which provides convenience for the operation of the clamping frame 82.

[0043] like Figure 12-14 As shown, the fixing assembly 8 also includes: a support frame 81 fixedly mounted on the front side of the casing 1; an oblique contact portion is provided on the rear side of the support frame 81, and an oblique contact portion is also provided on the front sides of the two clamping frames 82. The support frame 81 can contact the oblique surfaces of the two clamping frames 82 respectively. When the containing plate 4 is moved to the front side of the casing 1, the two clamping frames 82 will both contact the support frame 81, and as the clamping frames 82 continue to move forward, the two clamping frames 82 are slid apart to the left and right sides by the support frame 81, and the spring Z83 is deformed, so that the fixing effect of the clamping frames 82 on the PCB board 11 can be automatically released, and manual operation is no longer required, which facilitates the removal of the PCB board 11. On the contrary, after the PCB board 11 is placed on the containing plate 4, the containing plate 4 moves backward, and the clamping frames 82 are separated from the support frame 81. Then, the spring Z83 acts to enable the clamping frames 82 to clamp and fix the PCB board 11, so that the loading of the PCB board 11 becomes more convenient and simple.

[0044] like Figure 12-14 As shown, the fixing assembly 8 also includes: an opening rack 86 fixedly connected to the expansion frame 81, the opening rack 86 meshing with the column gear 84. No matter at what angle the expansion frame 81 rotates and moves to the front side of the casing 1, after the column gear 84 contacts with the opening rack 86, the opening rack 86 will rotate the column gear 84, thereby driving the two synchronous racks 85 to slide and separate to the left and right sides respectively, that is, to open the two clamping frames 82, and release the clamping of the clamping frames 82 on the PCB board 11. In this way, when the PCB board 11 needs to be removed, there is no need to specially adjust the clamping frame 82 to contact the inclined surface of the expansion frame 81 before the PCB board 11 can be removed, thereby optimizing the setting of the clamping frame 82 and facilitating the use of the leveling device.

[0045] like Figure 15-16As shown, it also includes an inspection component 9 for quickly observing whether the PCB board 11 has been leveled; the inspection component 9 includes: a mounting plate 91 fixedly mounted on the upper front side of the through-hole of the housing 1; a straight plate 92 slidably mounted on the mounting plate 91, and after the straight plate 92 slides downward, its bottom can contact the PCB board 11; and a fixing member 93 arranged on the straight plate 92, the fixing member 93 is composed of a connecting plate fixed on the straight plate 92, a positioning block slidably connected to the connecting plate, and a spring fixedly connected between the connecting plate and the positioning block, the positioning block is slid, and the straight plate 92 is slid upward to move the positioning block to the top of the connecting plate, and the positioning block is released, so that the spring action will The positioning block moves on the mounting plate 91, and the flat plate 92 is supported on the mounting plate 91 by the fixing member 93, that is, the flat plate 92 is fixed on the mounting plate 91. When the flat plate 92 needs to be used, the positioning block is slid forward, the spring is deformed, and the flat plate 92 can slide downward and move to the top of the PCB board 11 that has been leveled. The positioning block is released, and the spring is restored. At this time, the fixing member 93 is below the mounting plate 91. After that, the user can judge the leveling effect of the PCB board 11 according to the gap size between the flat plate 92 and the PCB board 11, and choose whether to perform leveling again. After completion, operate the fixing member 93 to move the flat plate 92 up and fix it on the mounting plate 91.

[0046] like Fig.17 As shown, it also includes a loading tray 10 fixedly connected to the housing 1, and the PCB board 11 can be loaded in the loading tray 10, which is convenient for storing and accessing the PCB board 11.

[0047] The above embodiments are only specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
