[0040] A pressure sensor is installed on the sensing plate 5057.

[0041] It also includes a cleaning unit; the cleaning unit is connected to the upper left side of the first mounting plate 2; the cleaning unit is connected to the conveying unit; the cleaning unit includes an adsorption net 601, a fifth mounting frame 602, a guide frame 603, a motor 604, and a fan impeller 605; the fifth mounting frame 602 is bolted to the upper left side of the first mounting plate 2; the guide frame 603 is welded to the middle of the front side of the fifth mounting frame 602; the motor 604 is fixedly connected to the upper front side of the fifth mounting frame 602; the fan impeller 605 is fixedly connected to the output shaft of the motor 604; the fan impeller 605 is located inside the guide frame 603; the adsorption net 601 is slidably connected between the second limiting plate 205 and the third limiting plate 206.

[0042] The second limiting plate 205 and the third limiting plate 206 are provided with grooves on opposite sides, and the adsorption net 601 slides in the grooves.

[0043] The upper part of the guide frame 603 is set as a cylindrical tube.

[0044] During operation, the operator places the circuit board into the grooves on the upper parts of the first limiting plate 204, the second limiting plate 205, and the third limiting plate 206. These three plates secure the circuit board in place. Then, the operator controls the starter motor 604 to rotate the fan impeller 605. The fan impeller 605 generates airflow that blows dust away from the circuit board's surface and onto the adsorption net 601, where it collects the dust. This process cleans the circuit board. Next, the operator controls the starter motor 201 to move the first electric slider 202 to the left. Block 202 drives the second mounting plate 203, the first limiting plate 204, the second limiting plate 205, and the third limiting plate 206 to move to the right. The circuit board moves accordingly until its left end is directly below the first pressure roller 3014. The dome sticker is pre-rolled onto the electric feeding roller 302 with the bottom paper of the dome sticker facing down. It passes through the first electric rotating roller 304, the second electric rotating roller 305, and the inclined plate 307 in sequence. At the left end of the inclined plate 307, the bottom paper is torn open and wrapped around the electric receiving roller 303. That is, the bottom paper of the dome sticker is separated at the left end of the inclined plate 307, so that the dome sticker is exposed on the inclined plate. 307. The left end of the dome sticker is directly below the first pressure roller 3014. Then, the second electric slide rail 308 is activated to drive the second electric slider 309 downward. The second electric slider 309 drives the fourth mounting plate 3010, the first straight spring 3011, the guide rod 3012, the first mounting block 3013, and the first pressure roller 3014 to move downward. The first pressure roller 3014 presses the dome sticker onto the left end of the circuit board. Then, the electric feeding roller 302, the first electric rotating roller 304, the second electric rotating roller 305, and the electric receiving roller 303 are activated to rotate, so that the dome sticker and the backing paper are not... The circuit board moves to the left, and the first electric slide rail 201 is activated to drive the first electric slider 202 to move to the left. The first electric slider 202 drives the second mounting plate 203, the first limiting plate 204, the second limiting plate 205, and the third limiting plate 206 to move to the left, thus moving the circuit board to the left. This allows the dome sticker to be applied from the left end to the right end of the circuit board. After the sticker is applied, the electric feeding roller 302, the first electric rotating roller 304, the second electric rotating roller 305, and the electric receiving roller 303 are turned off, so that the dome sticker stops moving, while the circuit board continues to move to the left, thus tearing the dome sticker.

[0045] After the dome switch stickers are applied to the circuit board, the dome switches are arranged in a rectangular array. At this point, the stickers are not completely adhered to the circuit board, posing a risk of detachment during subsequent use. The circuit board continues to move to the left, passing sequentially through the second pressure roller 402 and the pressure rod 405. When passing the second pressure roller 402, its cam presses the stickers between the dome switches in the front-to-back direction onto the circuit board. The pressure rod 405 presses the stickers between the dome switches in the left-to-right direction onto the circuit board, ensuring a tight adhesion between the circuit board and the dome switch stickers and preventing detachment. When the dome switches pass the pressure rod 405, it forces the rod to move upwards. This upward movement of the pressure rod 405 causes four connecting rods 404 to slide upwards within the fifth mounting plate 403. The four connecting rods 404 then move the spring telescopic plate 406 and the two first wedge blocks 407 upwards. As the spring telescopic plate 406 moves upwards, its extension... The retracted end contacts the convex plate on the upper part of the needle 4013, which then drives the needle 4013 to move upward and compress the second straight spring 4012. The spring telescopic plate 406 continues to move upward, causing the two first wedge blocks 407 to contact the two second wedge blocks 409, forcing the two first wedge blocks 407 to move to the right. The two first wedge blocks 407 drive the telescopic end of the spring telescopic plate 406 to compress, so that the telescopic end of the spring telescopic plate 406 no longer drives the needle 4013 to move upward. After that, the dome switch is located directly below the needle 4013 after passing the pressure rod 405. Due to the elastic force of the second straight spring 4012, the needle 4013 moves downward and pokes the dome switch sticker, causing holes to be punched in the stickers on both sides of the dome switch for ventilation and to facilitate pressing down the dome switch. The pressure rod 405 descends and resets due to gravity, and at the same time, the telescopic end of the spring telescopic plate 406 also resets due to the extension of the internal spring.

[0046] Then, continue controlling the circuit board to move to the left, so that the circuit board is directly below the four detection mechanisms 505. Then, control the activation of the two third electric slide rails 502 to drive the two third electric sliders 503 to move downwards. The two third electric sliders 503 drive the ninth mounting plate 504 to move downwards. The ninth mounting plate 504 drives the electric push rod 506, the tenth mounting plate 507, the rack 508, and the detection mechanism 505 to move downwards to detect the bonding strength between the dome switch and the circuit board. When the rightmost detection mechanism 505 is working, the four detection rods 5054 move down to contact the dome switch and gently press it. At the same time, the two sensing plates 5057 contact the surface of the circuit board. First, control the activation of the front electric push rod 506 to drive the tenth mounting plate 507 and the rack 508 to descend. The rack 508 drives the front gear 5055 to rotate counterclockwise with the front-to-back view as the reference. The front gear 5055 drives the transmission shaft 5052 and the second mounting block 505. 3. The detection rod 5054 rotates counterclockwise, causing it to move to the left while pressing the dome switch, thus rubbing it. This simulates the action of a person pressing and rubbing the dome switch during use. If the dome switch is not firmly bonded to the circuit board, it will move and come into contact with the sensing plate 5057 behind it. The sensing plate 5057 is equipped with a pressure sensor that can detect the movement of the dome switch, thus determining whether the bonding strength between the dome switch and the circuit board is qualified. Similarly, the electric push rod 506 behind it is then activated to drive the tenth mounting plate 507 and the rack 508 to descend, causing the detection rod 5054 to rotate clockwise, and the bonding strength between the dome switch and the circuit board is tested again. Then, the circuit board is moved to the left until it is directly below the guide frame 603.
