Description

Technical Field

[0001] The invention relates to the field of PCB board processing, and in particular to a PCB board processing fixing clamping table. Background Art

[0002] During the processing of PCB boards, the board surface is scanned by automatic optical inspection equipment. The purpose of the scan is to determine whether there are defects in the circuit, solder joints and appearance of the PCB board, such as disconnection, fracture, white spots or white solder exposure. The presence of dust particles on the PCB board surface will cause the inspection equipment to misjudge, so these undetermined "defective products" usually need to be manually re-inspected. If it is determined to be a defective product, it is necessary to repair the fracture, white spots, and tin deficiency according to the defect situation. When repairing the PCB board, the board needs to be fixed and clamped. When repairing defective products in a centralized manner, it is necessary to manually change the board frequently, and the clamping table will clamp multiple boards at the same time, which is inconvenient to operate when manually dispensing glue and spot welding.

Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. It can be understood that the specific embodiments described herein are only used to explain the present application, rather than limiting the present application. In addition, it should be noted that, for the convenience of description, only the parts related to the present application are shown in the drawings rather than all the structures. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0037] In the description of the present application, it should be noted that, unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection, an electrical connection, or a communication with each other; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0038] The present invention specifically discloses a PCB board processing and fixing clamping table, as Figure 1-Figure 16As shown, it includes: a T-shaped frame 1 and a convex ring rail 2, the convex ring rail 2 is vertically installed on the T-shaped frame 1, the convex ring rail 2 is in a "convex" shape, and there is a convex part in the middle to guide the object to climb up and then fall down, and a plurality of clamps 4 are evenly arranged on the convex ring rail 2, the clamps 4 slide on the convex ring rail 2, and the clamps 4 are connected in series by steel ropes 3, so that the movement of any clamp 4 will move with the other clamps 4, and after the sheet material 200 to be repaired is clamped by the clamp 4, the sheet material 200 is brought to the convex part of the convex ring rail 2 as the clamp 4 moves. At this time, the sheet material 200 at the convex part of the convex ring rail 2 is placed alone in the air, and there is enough operating space for repair operations without the interference of other sheets 200.

[0039] according to Figure 1 and Figure 6 As shown, a first top plate 5 is fixedly installed on one side of the T-shaped stand 1, and the top of the first top plate 5 is in sliding contact with the clamp 4. When the clamp 4 moves, it contacts the first top plate 5. By supporting the clamp 4 with the first top plate 5, the clamp mouth of the clamp 4 can be opened. While the clamp mouth is opened, the sheet 200 can be inserted into the clamp mouth. As the clamp 4 continues to move, it is out of contact with the first top plate 5, and the clamp mouth of the clamp 4 is closed to clamp the sheet 200.

[0040] A slide rail 6 is fixedly installed on one side of the T-shaped stand 1, and the slide rail 6 and the first top plate 5 are on the same side. A slide sleeve 7 is slidably mounted on the slide rail 6, and an inclined top tooth 71 is movably installed on the slide sleeve 7 through a spring pop-up method. The telescopic push rod 8 is installed on the T-shaped stand 1 and is connected to the slide sleeve 7. When the movable rod of the telescopic push rod 8 is extended, the slide sleeve 7 moves accordingly, and the inclined top tooth 71 slides from the bottom of the clip 4 until the inclined top tooth 71 passes over the clip 4 and bounces up to abut against the edge of the clip 4. The telescopic push rod 8 is retracted to a distance equal to the spacing distance between the clips 4. During the movement of the slide sleeve 7, the inclined top tooth 71 abutting against the edge of the clip 4 pushes the clip 4 to move, causing the clip 4 to climb toward the raised part of the convex ring rail 2. During the process of the inclined top tooth 71 pushing the clip 4 to move, the clip 4 contacts the first top plate 5, and when the slide sleeve 7 moves to half of the predetermined distance, the clip 4 is out of contact with the first top plate 5. Figure 3 As shown, the sliding sleeve 7 is on the right side of the convex ring rail 2, and the clamp 4 moves to the left side, and finally makes the clamp 4 stay at the center position of the raised part of the convex ring rail 2 to perform the repair operation of the sheet 200, and each intermittent push and pull of the telescopic push rod 8 will make the clamps 4 at the back stay one by one at the center position of the raised part of the convex ring rail 2, and the position of the raised part serves as the repair area, which can orderly make the clamps 4 clamping the sheet 200 perform the repair operation one by one.

[0041] according to Figure 1 and Figure 6As shown in the figure, a sheet-by-sheet pushing mechanism 10 is installed on the T-shaped gantry 1 through a connecting frame 9. The sheet-by-sheet pushing mechanism 10 is located above the slide rail 6. While the clamping mouth of the clamp 4 is opened, the sheet-by-sheet pushing mechanism 10 pushes the sheet material 200 into the clamping mouth. After the clamp 4 disengages from the first top plate 5, the clamping mouth closes to clamp the sheet material 200, thereby realizing the automatic supply of the sheet material 200 required to be clamped by the clamp 4. According to Figure 1 As shown in the figure, a second top plate 11 is fixedly installed on the T-shaped gantry 1 on the side far from the first top plate 5. The second top plate 11 has the same function as the first top plate 5. The top of the second top plate 11 is in sliding contact with the clamp 4 and causes the clamp 4 to open. The protruding part of the convex ring rail 2 is located between the first top plate 5 and the second top plate 11. Therefore, the sheet material 200 moves from the position of the first top plate 5 towards the protruding part, falls after being repaired, and contacts the second top plate 11. At this time, the clamp 4 opens, and the clamped sheet material 200 falls and finally lands in the receiving frame 12. The receiving frame 12 is installed on the T-shaped gantry 1 and is located below the second top plate 11. After the clamp 4 releases the sheet material 200, it will return to the position of the first top plate 5 again during the process of following the convex ring rail 2 and wait to clamp the next sheet material 200.

[0042] According to Figure 4 As shown in the figure, the clamp 4 includes: a U-shaped mounting block 42. The U-shaped mounting block 42 is provided in the convex ring rail 2 by rolling through rollers 41. A flat mouth clamp 43 is installed on the U-shaped mounting block 42. The flat mouth clamp 43 contacts the first top plate 5 and the second top plate 11 respectively during the movement process, and the clamping mouth opens during the contact process. A buffer rubber is provided at the clamping mouth of the flat mouth clamp 43, which can make the flat mouth clamp 43 more stable when clamping the sheet material 200 and will not damage the sheet material 200 at the same time.

[0043] According to Figure 4 As shown in the figure, a positioning rotating shaft 44 is installed on the U-shaped mounting block 42. The flat mouth clamp 43 is rotatably arranged on the U-shaped mounting block 42 through the positioning rotating shaft 44. After the sheet material 200 moves to the protruding part of the convex ring rail 2, the sheet material 200 can be deflected by a certain angle by rotating the clamp 4, so as to obtain a better operation experience when repairing the sheet material 200. At this time, since the clamp 4 can rotate, in order to prevent the clamp 4 from deflecting when contacting the first top plate 5 and the second top plate 11 during the movement process, resulting in a deviation in the clamping angle with the sheet material 200, a pressing plate 45 is hingedly installed on the U-shaped mounting block 42. At this time, the clamp 4 uses the pressing plate 45 as an intermediate plate to contact the first top plate 5 and the second top plate 11 and press down the flat mouth clamp 43 to open, and the pressing plate 45 will not rotate during the contact with the first top plate 5 and the second top plate 11.

[0044] According to Figure 4 and Figure 5As shown in the figure, the positioning rotating shaft 44 includes: an outer ring 441 fixedly arranged on the flat mouth clip 43, with T-shaped elastic blocking teeth 442 evenly arranged at intervals in the inner ring of the outer ring 441, a gear 443 fixedly installed on the C-shaped mounting block 42, the outer ring 441 is sleeved on the gear 443, and the T-shaped elastic blocking teeth 442 abut against the gear 443. The rotation of the clip 4 is completed by the outer ring 441 rotating around the gear 443. Therefore, during the rotation process, the T-shaped elastic blocking teeth 442 inside the outer ring 441 will bend and deform, and as the outer ring 441 rotates, they will abut against the tooth grooves at different positions of the gear 443. After the rotation of the clip 4 stops, it will be kept in a fixed position and not easily deflected by the T-shaped elastic blocking teeth 442 abutting against the tooth grooves of the gear 443.

[0045] According to Figure 6-Figure 12 As shown in the figure, the sheet-by-sheet feeding mechanism 10 includes: a square frame formed by surrounding and connecting a first side plate 101, a blocking plate 102, a second side plate 103, and an L-shaped edge wrapping plate 104. Specifically, the blocking plate 102 is vertically installed on the first side plate 101, the second side plate 103 is vertically installed on the blocking plate 102, the first side plate 101 and the second side plate 103 are parallel to each other, the L-shaped edge wrapping plate 104 is connected to the same side of the first side plate 101 and the second side plate 103, and the bottom of the L-shaped edge wrapping plate 104 is connected to the first side plate 101, and there is a passing gap 105 allowing the sheet material 200 to slide out between the bottom of the blocking plate 102 and the second side plate 103 and the L-shaped edge wrapping plate 104. After the sheet materials 200 are stacked in the square frame, the sheet material 200 at the bottom slides out from the passing gap 105. There is a notch on the L-shaped edge wrapping plate 104, and the stepped top plate 106 slides on the notch opened on the L-shaped edge wrapping plate 104.

[0046] According to Fig.12 As shown in the figure, after the stepped top plate 106 slides to the left, the sheet material 200 inside the square frame will slide to the left under the push of the raised step of the stepped top plate 106, slide out from the passing gap 105, and finally enter the clip 4 with the jaws open. As the clip 4 moves away from the first top plate 5, the clip 4 clamps the sheet material 200, and during the continuous movement of the clip 4, the sheet material 200 is drawn out from the passing gap 105 on the side of the second side plate 103, so that the sheet material 200 is separated from the square frame.

[0047] A telescopic push block 107 is fixedly installed at the bottom of the L-shaped edge wrapping plate 104. One end of the pull rod 108 is connected to the stepped top plate 106, and the other end is slidably arranged at the bottom of the L-shaped edge wrapping plate 104. The movable end of the telescopic push block 107 is connected to the pull rod 108. By driving the pull rod 108 to move through the telescopic push block 107, the stepped top plate 106 can be moved, and thus the sheet material 200 can be pushed to slide out from the passing gap 105.

[0048] The present invention arranges a plurality of clamps 4 on the convex ring rail 2, and connects them in series through steel ropes 3, and then uses the inclined top teeth 71 on the sliding sleeve 7 to push the clamps 4 to move. During the movement of the clamps 4, the clamping mouth is opened, and at the same time, the sheet 200 is sent out by cooperating with the sheet pushing mechanism 10 so that the clamps 4 clamp the sheet 200. After the sheet 200 moves to the raised part of the convex ring rail 2, the sheet 200 can be repaired. This process realizes automatic and continuous feeding and unloading of the sheet 200, and puts the single sheet 200 in a fixed protruding position, so that there is enough operating space to facilitate the repair of the sheet 200.

[0049] An outer shell can be installed on the T-shaped stand 1 to cover the other parts except the raised part of the convex ring rail 2 by the outer shell.

[0050] according to Fig.12 As shown, resistance rods 109 are provided on the side walls of the first top plate 5 and the second top plate 11 of the square frame. The resistance rods 109 have protruding extension teeth. When more sheets 200 are stacked in the square frame, the extension teeth are kept in an oblique downward state by torsion springs against the edges of the sheets 200. The extension teeth can buffer the falling tendency of the sheets 200 when multiple sheets 200 are stacked, thereby preventing the sheets 200 at the bottom from being tightly pressed and difficult to be pulled out by the clips 4 when sliding out through the gap 105.

[0051] according to Figure 1 and Fig.13 As shown, it also includes: a blocking rod 13 installed on the material receiving frame 12, the blocking rod 13 is located on the side away from the first top plate 5, after the clamp 4 is opened through the second top plate 11, if the sheet 200 does not fall from the clamp 4, the sheet 200 will hit the blocking rod 13 during the continuous movement of the clamp 4, and the blocking rod 13 will prevent the sheet 200 from continuing to move with the clamp 4, so that the sheet 200 can fall into the material receiving frame 12, and the end of the second top plate 11 is flush with the position of the blocking rod 13.

[0052] according to Figure 1 , Fig.14 and Fig.15 As shown, it also includes: a mounting plate 14 fixedly mounted on the T-shaped frame 1, the top of the mounting plate 14 is in the raised part area of ​​the convex ring rail 2, one end of a support 143 is hingedly mounted on the top of the mounting plate 14, the support 143 and the mounting plate 14 are jointly connected to the diagonal support assembly, and the support 143 is diagonally supported by the diagonal support assembly to keep the support 143 in a straight state, so that after the sheet material 200 moves to the raised part of the convex ring rail 2, the sheet material 200 can be supported from the bottom by the support 143 to prevent the sheet material 200 from swinging up and down.

[0053] according to Fig.14 , Fig.15 and Fig.16As shown, the diagonal brace assembly includes: an inverted tooth plate 141 fixed on both sides of the mounting plate 14, the inverted tooth plate 141 is provided with inverted teeth at intervals, a limit plate 142 connected to the inverted tooth plate 141, a gap is left between the limit plate 142 and the inverted tooth plate 141, one end of the support frame 144 is hinged to the edge of the support platform 143, the other end of the support frame 144 is hinged to the positioning plate 145, the positioning plate 145 is provided with a non-returning tooth 1451 opposite to the inverted tooth plate 141, and the positioning plate 145 is located between the inverted tooth plate 141 and the limit plate 142. When in use, the support platform 143 is lifted up to keep it in a straight state, and the positioning plate 145 is lifted up with it, and the non-returning tooth 1451 on the positioning plate 145 is pressed against the inverted tooth, so as to prevent the support platform 143 from falling. When the support platform 143 needs to be lowered, it only needs to separate the non-returning tooth 1451 from the inverted tooth to make the positioning plate 145 move down, and the support platform 143 is retracted accordingly.

[0054] according to Fig.16 As shown, it also includes: trapezoidal spring leaves 1452 are fixedly installed on both sides of the positioning plate 145, and the trapezoidal spring leaves 1452 are against the limiting plate 142. The function of the trapezoidal spring leaves 1452 is to enable the non-return tooth 1451 to be tightly attached to the inverted tooth, so that the non-return tooth 1451 will not easily separate from the inverted tooth when the support platform 143 is supported.

[0055] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
