Description

[0022] A filter screen 106 is also included; the filter screen 106 is fixedly connected to the water outlet 10102.

[0023] A water storage tank 10103 is provided at the lower front portion of the water storage chamber 10101.

[0024] An extension plate 109 is also included; the front side of each clamping block 108 is slidably connected to the extension plate 109 .

[0025] During the copying process, when the worker is grinding the circuit board 555, he not only needs to use the handheld grinder 4 to grind the circuit board 555, but also needs to press the circuit board 555 to prevent the circuit board 555 from shifting. The operation is extremely inconvenient, time-consuming and laborious. In addition, in order to facilitate the observation of the grinding condition of the circuit board 555, the worker needs to constantly clean the circuit board 555 during the grinding process, which seriously affects the grinding efficiency.

[0026] In order to solve the above-mentioned problem, the present invention proposes the following method: first, the worker puts the circuit board 555 to be polished into the working area 1001; then the worker can grasp the handle 103 to adjust, drive the connector 102 to slide back and forth in the first slide groove 1002, and then adjust the position of the sliding block 101, so that the working area 1001 in front of the sliding block 101 has space to accommodate the circuit board 555 to be polished but not too far away from the worker, so that the worker can perform the polishing operation more comfortably, and ensure that the front side of the circuit board 555 does not contact the wall of the working area 1001, leaving space for the movement of the grinder 4 ; Then, the rear end of the circuit board 555 is placed against the front side of the sliding block 101, and the position only needs to be roughly aligned with the middle position of the sliding block 101, and there is no need to align it carefully; then the worker grabs the hand-held portion 10501 with his hand; and uses the hand-held portion 10501 to move the sliding plate 105 left and right; and then drives the clamping block 108 to move left and right through the first connecting block 107, and clamps and fixes the left and right sides of the circuit board 555 through the two clamping blocks 108. During this process, the sliding plate 105 slides in the second slide groove 10104; after adjusting the position, the worker can screw the handle 103 , and then the bolt on the lower side of the handle 103 is rotated and moved downward, and the bottom of the bolt contacts the lower surface of the first slide groove 1002, thereby increasing the sliding resistance of the connector 102, and then locking the sliding block 101, and the bolt on the handheld part 10501 is similar, thereby fixing the clamping block 108; then the worker can start the grinder 4; then grab the grinder 4 by hand, and through the movement of the hand, drive the grinder 4 to move left and right on the second sliding member 3, and move forward and backward on the first sliding member 2, thereby easily moving the grinder 4 to the desired grinding position; and when grinding, the worker only needs to press the grinder downward with his hand The spring telescopic rod 202 will be retracted and reset immediately, thereby driving the grinder 4 and the grinder 4 to move upward. After the grinding sheet moves upward, the worker can check the grinding condition of the circuit board 555, adjust the grinding condition in time, and improve the grinding effect of the copy board.

[0027] However, during the grinding process, as the use time of the grinder 4 increases, the temperature of the grinding sheet will accumulate and rise, which can easily cause damage to the grinding sheet and even damage the thin copper foil layer. Therefore, it is necessary to cool down during the grinding process. In existing equipment, a cooling water pipe is usually installed on or around the grinder 4, and then the grinder 4 is flushed and cooled by the cooling water pipe. However, when grinding the copy board, the worker needs to perform fine grinding on the circuit board 555, and at the same time, he must always observe the grinding status. Directly using a water pipe to flush and cool down will produce more cooling water near the grinding area, and it is easy to form a chaotic water flow, which affects The worker observes and judges the grinding status; therefore, the worker can start the water circulation system in the water tank 5. At this time, the cooling water in the water tank 5 will enter the water storage chamber 10101 through the water inlet pipe 104. However, if there is no restriction, the water entering the water storage chamber 10101 will first flow out from the right side of the water outlet 10102, resulting in a smaller water flow on the left side of the water outlet 10102. Therefore, a water storage tank 10103 is provided at the lower front part of the water storage chamber 10101. The water entering the water storage chamber 10101 will first enter the water storage tank 10103. When the water in the water storage tank 10103 exceeds the water outlet 10102, the water flow will will flow out from the water outlet 10102; and at this time, the water will flow out evenly and slowly from the entire water outlet 10102, and flow into the upper side of the circuit board 555. At this time, the left and right sides of the circuit board 555 are clamped by the clamping block 108, and the thickness of the clamping block 108 is greater than the thickness of the circuit board 555. Therefore, the water flow will be blocked by the clamping block 108, and then will flow from the back side to the front side of the upper surface of the circuit board 555 without overflowing to the left and right sides, and a thin layer of flowing cooling water will be formed on the upper surface of the circuit board 555; at the same time, workers can add softening agents to the cooling water. When the workers are softening the green film on the surface of the circuit board 555 During grinding, the cooling water with added chemicals can not only soften the green film and reduce the difficulty of handling; at the same time, the grinder 4 will generate more dust and impurities when grinding the green film. At this time, the circuit board 555 is moistened by cooling water to prevent dust and impurities from being raised to the atmosphere, damaging the working environment and even causing harm to the workers. The water in the water layer continues to flow in a relatively calm manner to carry away the debris and dust generated by grinding. When the worker removes the grinder 4, the water flow can be restored to calm in a very short time from the chaotic state stirred by the grinder 4, avoiding dust and chaotic cooling water flow from gathering near the grinding area for a long time, affecting the workers' observation and judgment of the grinding status.

[0028] At the same time, when the sliding plate 105 drives the clamping block 108 to move and clamp the circuit board 555, as shown in FIG. Figure 5 and Figure 8As shown: the sealing portion 10502 will move with the sliding plate 105, that is, it will move synchronously with the clamping block 108. At this time, because the first edge surface 10503 is flush with the second edge surface 10801, part of the water outlet 10102 will exceed the width range of the circuit board 555. If this part of the area is not treated and allowed to continue to discharge water, the water will not flow to the surface of the circuit board 555 but to other positions of the working area 1001, and will not play any role and will be wasted. Therefore, for the area outside the clamping area of ​​the clamping block 108, this part of the water outlet 10102 is 2 will be sealed by the sealing portion 10502 to prevent water from flowing out of these regional spaces and being unable to flow into the upper surface of the circuit board 555, resulting in waste; therefore, when clamping some circuit boards 555 of different sizes but all within the coverage range of the water outlet 10102, after the clamping action is completed, the distance between the two second edge surfaces 10801 is both the width of the circuit board 555 and the width of the water outlet 10102 that can discharge water, and this width can change with the circuit board 555, and the adjustment process is achieved along with the clamping and fixing process, which is easier to use and more convenient.

[0029] By using the extension plate 109, when encountering a longer circuit board 555, the extension plate 109 can be pulled out to adapt to the grinding of circuit boards 555 of different sizes; because the overall volume of the clamping block 108 and the extension plate 109 is not large, after extension, such as Figure 6 The gap between the two is actually very small, and the gap is not connected to the outside world, so there will be no water outflow, and it has almost no effect on the anti-dust effect.

[0030] Finally, the cooling water will flow into the drain outlet 1003 on the front side of the working area 1001, and finally flow back into the water tank 5, and re-enter the water storage chamber 10101 after being filtered, thereby realizing recycling; it should be noted here that in order to prevent the grinder 4 from touching the clamping block 108, the extension plate 109 and the sliding block 101 during the grinding process, only the edge of the four edges of the upper surface that is not in contact with the clamping block 108, the extension plate 109 and the sliding block 101 can be completely in contact with the grinding sheet, so the other three edges that cannot be completely processed need to alternately rotate the circuit board 555 for additional processing.

[0031] Example 2 On the basis of Example 1, Fig. 9 and Fig.10As shown, it also includes a limit slider 203, a screw rod 204, a rotator 207 and an adjustment button 208; the screw rod 204 is rotatably connected in the second connecting block 201; the limit slider 203 is rotatably connected on the screw rod 204; the limit slider 203 slides in the third slide groove 20101, and the limit slider 203 is located on the lower side of the connecting plate 206; the lower end of the screw rod 204 is connected to the rotator 207, and the rotator 207 is located in the third slide groove 20101; two adjustment buttons 208 are fixedly connected to the right part of the rear side of the grinder 4; each adjustment button 208 is electrically connected to the rotator 207.

[0032] It also includes a supporting plate 209 ; the supporting plate 209 is fixedly connected to the lower side of the grinder 4 .

[0033] The supporting plate 209 is rotatably connected to a flip plate 20901 , and the rotation angle range of the flip plate 20901 is 90 degrees between vertical and horizontal.

[0034] It also includes friction blocks 205; a plurality of friction blocks 205 are fixedly connected to the outer surface of the grinder 4, and the friction blocks 205 are made of rubber.

[0035] When grinding the circuit board 555, the worker needs to keep the grinder 4 at a certain height by pulling with his hands. The grinding process of the copy board is long, and the worker presses and pulls the grinder 4 for a long time, which is labor-intensive. In addition, the arm needs to be kept in the air for a long time. After working for a long time, the arm will inevitably feel tired and shake, which will affect the grinding work. Figure 9-10 As shown: the worker can grasp the area where the friction block 205 on the grinder 4 is located with his hand, and put his arm on the supporting plate 209. At this time, the friction block 205 increases the friction between the palm and the grinder 4, thereby improving the worker's control over the grinder 4, and the sponge material of the friction block 205 improves the comfort of the worker when grasping the grinder 4; at the same time, the worker's arm is placed on the supporting plate 209, so that the worker does not have to keep his arm suspended all the time, thereby reducing the worker's labor intensity and improving the convenience of operation; it should be noted here that when necessary, the worker can rotate the flip plate 20901 to an angle horizontal to the supporting plate 209, expand the supporting range of the supporting plate 209, and improve the supporting effect; when not in use, the flip plate 20901 can be rotated to an angle perpendicular to the supporting plate 209, and then the flip plate 20901 can be flipped up to reduce the floor space.

[0036] At the same time, after the worker grabs the grinder 4, he can press the two adjustment buttons 208 to control the rotator 207 to drive the screw rod 204 to rotate, drive the limit slider 203 to move up and down, and then limit the downward movement limit distance of the grinder 4; when encountering circuit boards 555 with different thicknesses, the height of the limit slider 203 can be adjusted by adjusting the button 208, and then the worker does not need to use his arm to pull the grinder 4 down to maintain the descending height of the grinder 4, which allows the worker to maintain a sitting position without any physical discomfort. Lean forward slightly, transfer part of your own weight through your palm and arm to press on the supporting plate 209, and press the grinder 4 down to the limit position. At this time, the connecting plate 206 is limited by the limiting slider 203, so that the grinder 4 is kept at a certain height, which is also more in line with the state that the worker wants to lean close to the circuit board 555 to observe the grinding situation; and when you want to move the grinder 4 away from the circuit board 555, as long as the body does not lean forward anymore, the spring telescopic rod 202 will naturally rebound and drive the grinder 4 away from the circuit board 555 to avoid damaging the circuit board 555.

[0037] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
