Description

Technical Field

[0001] The present invention relates to the technical field of ink leveling processing equipment, and particularly refers to an ink leveling machine that performs vertical ink leveling operations on the surface of a product to be ink leveled by means of a vertical leveling mechanism in cooperation with a thin film. Background Art

[0002] With the development of technology and the needs of product manufacturing, some PCB board processes have changed, and plug-hole printing is required to meet the process requirements. Some parts of these PCB boards have no circuits passing through, leaving holes that need to be blocked and separated by ink. When plugging the holes, the holes need to be completely filled with ink. However, in actual production, due to the different sizes of the holes on the circuit board, it is impossible to ensure the ink thickness and uniformity. Therefore, a double-sided leveling ink structure is needed for leveling to ensure that the ink fills the holes.

[0003] Currently, the general method is to use a drum-type ink leveling machine to level the product in a horizontal placement manner, acting on both sides of the PCB board, cooperating with a thin film, and attaching it to the surface of the PCB board, so that the PCB board passes through a drum with a thin film covering its surface, and the ink is squeezed to fill each hole on the PCB board. However, since the PCB board is placed horizontally, the ink in the holes will, under the influence of gravity, cause the phenomenon that the upper surface of the ink filled in the product is sunken and the bottom surface is protruding, and the surface of the product will be uneven. During the extrusion process, excess ink will be generated, and the thin film will drive away the excess ink. This ink that is taken away will be extruded from both sides of the thin film due to extrusion and contaminate the equipment. If the equipment is placed in a dust-free workshop and the ink contaminates the equipment, over time, the ink will dry and generate dust, failing to meet the dust-free requirements and affecting the appearance of the equipment. In addition, during the ink leveling process of the drum-type ink leveling machine, due to the large contact area, when the thin film detaches from the product, the ink that has been leveled will be adhered out of the holes, resulting in unqualified products. Summary of the Invention

[0004] The object of the present invention is to overcome the deficiencies in the prior art and provide a vertical ink leveling machine. This ink leveling machine ensures that the product can be better in a flat surface state during the ink leveling operation, which is more conducive to the smooth progress of the ink leveling operation and can effectively avoid the movement or subsidence of the ink; makes the product more stable during the ink leveling operation, not easy to shake, and better guarantees the effect of the ink leveling operation. At the same time, since the clamping area of the clamping and conveying unit can be adjusted according to the size of the product, the applicable range of the present invention is wider; ensures the accuracy of the force application position of the squeegee; can effectively avoid taking away too much ink due to the too large contact area between the film and the circuit board during the leveling process, can not only ensure the uniformity of ink filling in each hole position on the circuit board, but also effectively scrape away the excess ink after leveling, avoid the excess ink from contaminating the circuit board, ensure the yield rate of the product, and can also effectively save the use of the film, thereby effectively saving the production and processing costs.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A vertical ink leveling machine includes a frame. One side of the frame is provided with a clamping workbench, and the other side is provided with a leveling workbench.

Each lifting guide rod is connected to the top connecting plate through a linear sleeve. At least one position sensor is respectively provided at both ends of one side of the adjusting linear module, and the position sensor is used to limit the adjustment position of the dynamic pressure material cylinder.

[0009] The fixed clamping assembly includes a pneumatic finger cylinder and movable clamping blocks respectively arranged at both ends of the pneumatic finger cylinder through a movable connecting block. The two movable clamping blocks on the same pneumatic finger cylinder cooperate to clamp the product to be leveled with ink.

[0010] The double-head transport mechanism consists of two loading treadmills, treadmill slide rails respectively arranged on both sides of the corresponding treadmill bottom surfaces through at least one treadmill slider, a linkage bracket arranged between the two loading treadmill bottom surfaces, a treadmill linear module connected to the linkage bracket through a treadmill linkage block, a main drive motor connected to the linkage bracket through a main bracket, and a main transmission wheel arranged on the main drive motor. The main transmission wheel is transmission-connected to each tensioning mechanism through a chain, each treadmill slide rail is respectively connected to the leveling workbench through at least one support block, each tensioning mechanism is installed on the corresponding loading treadmill, and the treadmill linear module is installed on the bottom surface of the leveling workbench.

[0011] The two tensioning mechanisms are symmetrically arranged. Each tensioning mechanism includes a feeding air-expanding roller group provided on one side of the loading running table, a brake installed at the lower end of the feeding air-expanding roller group, a guiding and feeding roller group provided on one side of the feeding air-expanding roller group, a collecting air-expanding roller group provided on the other side of the loading running table, a synchronous driven wheel installed at the lower end of the collecting air-expanding roller group, a power driven wheel connected to one side of the lower end of the collecting air-expanding roller group through a synchronous connecting plate, and a first area feeding roller group and a second area feeding roller group provided between the collecting air-expanding roller group and the guiding and feeding roller group. The brake is used to detect the tension of the feeding air-expanding roller group and convert it into a signal for feedback. The first area feeding roller group and the second area feeding roller group are arranged relatively obliquely to form a leveling area. The vertical leveling mechanism is provided between the first area feeding roller group and the second area feeding roller group, and the tension constant mechanism is provided outside between the first area feeding roller group and the guiding and feeding roller group.

[0012] The tension constant mechanism includes a tensioning cylinder connected to the loading running table through a tension bracket, a tension connecting plate installed at one end of the tensioning cylinder, tension guide rods respectively installed at both ends of the tension connecting plate through connecting guide sleeves, and a tension pressing roller fixed at one end of the two tension guide rods.

[0013] The vertical leveling mechanism is composed of a leveling vertical frame, a leveling cylinder installed on the leveling vertical frame, a leveling knife group provided at one end of the leveling cylinder, and leveling guide rods respectively provided at both ends of the leveling knife group. Each leveling guide rod is respectively connected to the leveling vertical frame through a leveling guide sleeve.

[0014] One inner side of a column of the clamping and conveying unit is connected to a calibration part through a calibration bracket. The calibration part is used to calibrate the position of the vertical leveling mechanism in the empty machine state.

[0015] The beneficial effects of the present invention are as follows: The clamping and conveying unit adopts a vertical material clamping method to vertically clamp the product, making the clamping and conveying unit more suitable for PCB boards, avoiding sagging when the product is horizontally clamped, ensuring that the product is in a better flat surface state during the ink leveling operation, and being more conducive to the smooth progress of the ink leveling operation. Moreover, since the PCB board is vertically placed, the holes on the PCB board will play a certain blocking role on the ink, effectively avoiding the movement or sinking of the ink; The moving clamping component of the adjusting clamping component of the clamping and conveying unit cooperates with the adjusting linear module to adjust the clamping area in the horizontal direction, and then the linear screw motor cooperates with the vertical guide rail to adjust the clamping area in the vertical direction. In cooperation with the fixed clamping component and the static clamping component, the four corners of the product are clamped, making the product more stable during the ink leveling operation, not prone to shaking, and better ensuring the effect of the ink leveling operation. At the same time, since the clamping area of the clamping and conveying unit can be adjusted according to the product size, the applicable range of the present invention is wider; It forms a structure for winding and unwinding a film by cooperating the material receiving air expansion roller group and the material feeding air expansion roller group, applying a certain tension to the film, and then cooperating with the guiding material passing roller group to guide the feeding direction of the film. Combining with the included angle setting of the first area material passing roller group and the second area material passing roller group, a film area acting on the surface of the product to be ink leveled is formed between the first area material passing roller group and the second area material passing roller group, and the film is smoothly pulled from the material feeding air expansion roller group to the material receiving air expansion roller group; The setting of the tension constant mechanism applies an external force to the film according to the equipment preset before the ink leveling operation is carried out, so that the film normally maintains the preset tension value. When the vertical leveling mechanism acts on the film, the tension constant mechanism will gradually cancel the force applied to the film. Through the mutual cooperation of the tension constant mechanism and the vertical leveling mechanism, the film has a constant tension whether the equipment is performing the ink leveling operation or not. The brake timely monitors the tension value received by the material feeding air expansion roller group. When the tension received by the material feeding air expansion roller group disappears and the brake cannot detect the tension, it will feedback an electrical signal to the equipment console. The equipment console judges that the material feeding air expansion roller group is out of material according to the received electrical signal, pauses the equipment operation, and issues an alarm to the operator to remind the operator to replenish the film roll, so as to ensure the normal progress of the ink leveling operation; The calibration part is arranged on the column, and a calibration aperture is formed on the clamping frame body. The alignment of the blade of the leveling knife group is calibrated through the calibration aperture, so that the blade edge coincides with the calibration aperture to ensure the accuracy of the blade force application position;Its tensioning mechanism vertically unfolds the film, and cooperates with the scraper of the vertical leveling mechanism to press the film onto the surface of the product to be leveled with ink, forming a linear ink leveling contact position. Then, combined with the double-head conveying mechanism, the tensioning mechanism and the vertical leveling mechanism reciprocate to achieve the effect of ink leveling. This can effectively avoid taking away too much ink due to the excessive contact area between the film and the circuit board during the leveling process. It can not only ensure the uniformity of ink filling in each hole on the circuit board, but also effectively scrape away the excess ink after leveling, avoiding the contamination of the circuit board by the excess ink, ensuring the product qualification rate, and effectively saving the use of the film, thus effectively saving the production and processing costs.

[0032] As Figures 1-5 shown, the clamping and conveying unit 2 is connected to the clamping workbench 11 through a horizontal conveying linear module 4. One end of the horizontal conveying linear module 4 extends towards the leveling workbench 12. The clamping and conveying unit 2 is composed of a clamping bottom plate 21, a top connecting plate 23 provided on the top of the clamping bottom plate 21 through two columns 22, an adjustable clamping assembly 24 provided on the top connecting plate 23, a lower fixing plate 25 installed between the lower ends of the two columns 22, and at least one fixed clamping assembly 26 provided on the lower fixing plate 25.

Vertical guide rails 27 are respectively provided on the relatively inner sides of the two columns 22. Both ends of the adjustable clamping assembly 24 are respectively slidably connected to the vertical guide rails 27 on the corresponding side through vertical sliders 24h. Among them, an ink recovery tank 2a is further provided on the clamping bottom plate 21, and the ink recovery tank 2a is arranged below the lower fixing plate 25.

At least one conveying sensor (not shown) is respectively provided at both ends on one side of the horizontal conveying linear module 4, and a conveying induction piece (not shown) is provided on one side of the bottom slider 211. The conveying induction piece cooperates with the conveying sensor to limit the displacement range of the clamping and conveying unit 2, which not only ensures the accuracy of the conveying position of the clamping and conveying unit 2 for the product to be leveled with ink, but also ensures the accuracy of the reset of the clamping and conveying unit 2.

[0033] AsFigures 1-4As shown in the figure, the adjusting and clamping assembly 24 includes a linear screw motor 241 installed on the top connecting plate 23, a mounting cross plate 242 provided at one end of the linear screw motor 241, lifting guide rods 243 connected to both ends of the top surface of the mounting cross plate 242, an adjusting linear module 244 installed on one side of the bottom surface of the mounting cross plate 242, a moving pressure material fixing block 246 slidably connected to the adjusting linear module 244 through a moving intermediate connecting block 245, a moving punch fixing block 247 provided on the moving pressure material fixing block 246, a moving pressure material cylinder 249 installed at the connection of the moving pressure material fixing block 246 and the moving punch fixing block 247 through a moving cylinder fixing block 248, a first positioning block 24a installed at one end of the moving pressure material cylinder 249, a static intermediate fixing block 24b provided on the other side of the bottom surface of the mounting cross plate 242, a static punch fixing block 24c installed on the static intermediate fixing block 24b through a static pressure material fixing block, a static pressure material cylinder 24e installed at the connection of the static pressure material fixing block and the static punch fixing block 24c through a static cylinder fixing block 24d, and a second positioning block 24f installed at one end of the static pressure material cylinder 24e. Vertical fixing blocks 24g are provided at both ends of the mounting cross plate 242, and each vertical fixing block 24g is slidably connected to the vertical guide rail 27 on the corresponding side through a vertical slider 24h. Each lifting guide rod 243 is connected to the top connecting plate 23 through a linear sliding sleeve 24i. At least one position sensor 24j is provided at both ends of one side of the adjusting linear module 244, and the position sensor 24j is used to limit the adjusting position of the moving pressure material cylinder 249; the moving intermediate connecting block 245, the moving pressure material fixing block 246, the moving punch fixing block 247, the moving cylinder fixing block 248, and the moving pressure material cylinder 249 together constitute a moving clamping assembly; the static intermediate connecting block, the static pressure material fixing block, the static punch fixing block 24c, the static cylinder fixing block 24d, and the static pressure material cylinder 24e together constitute a static clamping assembly; wherein, an adjusting slider 244a is provided on the adjusting linear module 244, the adjusting slider 244a is connected to the moving intermediate connecting block 245, an adjusting induction piece 24k is provided on the adjusting slider 244a, and the adjusting induction piece 24k cooperates with the adjusting position sensor 24j to limit the adjusting area of the moving clamping assembly;On the outer side of one of the vertical columns 22, at least one lifting sensor (not shown) is respectively provided corresponding to both ends of the vertical guide rail 27. An lifting induction piece (not shown) is installed at the setting end of the installation cross plate 242 corresponding to the lifting sensor. The lifting induction piece is used to cooperate with the lifting sensor to limit the vertical displacement area of the adjustment clamping assembly 24, so as to prevent the adjustment clamping assembly 24 from detaching from the vertical guide rail 27 or colliding with the top connection plate 23 during the vertical displacement. The connection surfaces of the moving cylinder fixing block 248 and the moving pressure feeding cylinder 249, and the connection surfaces of the static cylinder fixing block 24d and the static pressure feeding cylinder 24e are both inclined surfaces, so that the moving pressure feeding cylinder 249 is inclined towards the moving punch fixing block 247 to cooperate with the moving punch fixing block 247 to clamp the product to be leveled with ink, and the static pressure feeding cylinder 24e is inclined towards the static punch fixing block 24c to cooperate with the static punch fixing block 24c to clamp the product to be leveled with ink.;

[0034] As Figure 1 , 3 , as shown in Figure 5, the fixed clamping assembly 26 includes a pneumatic finger cylinder 261 and moving clamping blocks 263 respectively arranged at both ends of the pneumatic finger cylinder 261 through a moving connection block 262. The two moving clamping blocks 263 on the same pneumatic finger cylinder 261 cooperate to clamp the product to be leveled with ink, and the pneumatic finger cylinder 261 is connected to the lower fixing plate 25.

[0035] In use, first, according to the width of the product to be leveled with ink, adjust the clamping assembly 24 to horizontally adjust the moving clamping assembly through the adjusting linear module 244 so that the distance between the moving clamping assembly and the static clamping assembly matches the width of the product to be leveled with ink. Then, the dynamic pressure cylinder 249 pushes the first positioning block 24a to clamp towards the moving punch fixing block 247, clamping one upper diagonal of the product to be leveled with ink. At the same time, the static pressure cylinder 24e pushes the second positioning block 24f to clamp towards the static punch fixing block 24c, clamping the other upper diagonal of the product to be leveled with ink. Then, the clamping assembly 24 adjusts the position of the mounting cross plate 242 in the vertical direction through the linear screw motor 241, so that the mounting cross plate 242 moves along the vertical guide rail 27. The moving clamping assembly and the static clamping assembly move vertically with the mounting cross plate 242, and the distance between the mounting cross plate 242 and the lower fixing plate 25 matches the height of the product to be leveled with ink. During the adjustment process of the position of the mounting cross plate 242, the pneumatic finger cylinders 261 of the respective fixed clamping assemblies 26 push the moving connection blocks 262 at both ends to open towards each other. At this time, the moving clamping blocks 263 connected to the respective moving connection blocks 262 also open. When the distance between the moving clamping assembly and / or the static clamping assembly and the fixed clamping assembly 26 matches the height of the product to be leveled with ink, the pneumatic finger cylinders 261 pull the moving connection blocks 262 at both ends to close towards each other. At this time, the respective moving clamping blocks 263 also close to clamp the diagonal of the lower end of the product to be leveled with ink, completing the vertical clamping of the product to be leveled with ink. Then, apply ink to both sides of the clamped product to be leveled with ink. Subsequently, the horizontal conveying linear module 4 drives the clamping and conveying unit 2 to feed towards the ink vertical leveling unit 3 through the bottom slider 211 to prepare for the ink leveling operation.

The first-region feeding roller group 328 and the second-region feeding roller group 329 are arranged relatively obliquely to form a flattening action region. A vertical flattening mechanism 33 is provided between the first-region feeding roller group 328 and the second-region feeding roller group 329, and a tension constant mechanism 34 is provided outside between the first-region feeding roller group 328 and the guiding and feeding roller group 323; specifically, the main driving wheel 319, the synchronous driven wheel 325, and the power driven wheel 327 are all arranged at the same horizontal height. The main driving wheel 319 and each power driven wheel 327 are connected by chain drive. At the same time, each synchronous driven wheel 325 is tangent to the chain to form a transmission structure; the main driving wheel 319, each synchronous driven wheel 325, and each power driven wheel 327 are connected to each other through the same chain to form a synchronous transmission structure to ensure the synchronous material receiving of each receiving air-expanding roller group 324; the first-region feeding roller group 328 and the second-region feeding roller group 329 are arranged at an angle.

[0038] Before use, the coil material 7 is sleeved on the feeding air-expanding roller group 321, and then an empty plastic coil is sleeved on the receiving air-expanding roller group 324. Then, one end of the film 71 on the coil material 7 is misaligned and passed through the guiding and feeding roller group 323, and then sequentially and misaligned through the first-region feeding roller group 328 and the second-region feeding roller group 329, and then connected to the empty plastic coil. Then, the tension constant mechanism 34 applies pressure to the film 71 between the first-region feeding roller group 328 and the guiding and feeding roller group 323 to keep the film 71 at a preset tension, completing the preparation of the film 71 before ink flattening.

[0039] Further, as shown in FIGS. Figure 1 , 3 6 and 10, the tension constant mechanism 34 includes a tension cylinder 342 connected to the loading running table 311 through a tension bracket 341, a tension connecting plate 343 installed at one end of the tension cylinder 342, tension guide rods 344 respectively installed at both ends of the tension connecting plate 343 through connecting guide sleeves 346, and a tension pressure roller 345 fixed at one end of the two tension guide rods 344.

[0040] During use, the tension cylinder 342 pushes the tension connection plate 343 to feed towards the film 71. At this time, the tension pressure roller 345 connected to the tension connection plate 343 through the tension guide rod 344 advances with the tension connection plate 343, and the tension pressure roller 345 presses on the film 71 between the first area material passing roller group 328 and the guiding material passing roller group 323, so that the film 71 maintains a preset tension; every time an ink leveling action is completed, the main driving wheel 319 drives each power driven wheel 327 through a chain. While driving each power driven wheel 327 to rotate, the chain also drives each synchronous driven wheel 325. At this time, each winding material air expansion roller group 324 connected to the synchronous driven wheel 325 rotates with each synchronous driven wheel 325, collects about 5 cm of the film 71, and recovers the film 71 that has undergone ink leveling treatment. While the winding material air expansion roller group 324 collects the film 71, it pulls the winding material 7 of the unwinding air expansion roller group 321 to unwind.

[0041] As Figure 1 、 3 、6, and 9 show, the vertical leveling mechanism 33 is composed of a leveling vertical frame 331, a leveling cylinder 332 installed on the leveling vertical frame 331, a leveling knife group 333 provided at one end of the leveling cylinder 332, and leveling guide rods 334 respectively provided at both ends of the leveling knife group 333. Each leveling guide rod 334 is respectively connected to the leveling vertical frame 331 through a leveling guide sleeve 335; among them, the leveling knife group 333 includes a knife connection plate 333a connected to the leveling cylinder 332, an angle rod 333b connected to the knife connection plate 333a, a balance weight (not shown) connected to the angle rod 333b through two locking clips 333c, a balance sleeve 333d sleeved outside the balance weight, a knife rest 333f connected to the balance sleeve 333d through at least one knife clip 333e, and a scraping knife 333g provided on the knife rest 333f.

[0042] Furthermore, as Figure 1 、 2As shown, one inner side of a column 22 of the clamping and conveying unit 2 is connected to a calibration part 5 through a calibration bracket 51. The calibration part 5 is used to calibrate the position of the vertical leveling mechanism 33 in the empty machine state, ensuring that the acting positions of the scraping blades 333h of the two vertical leveling mechanisms 33 on the two sides of the product to be leveled with ink correspond, ensuring that the scraping blades 333h are stressed simultaneously at the symmetrical positions on the two sides of the product, effectively avoiding damage to the product when the two scraping blades 333h act on the product surface at the same time, and ensuring the ink leveling effect and the yield rate of the product; wherein, the calibration part 5 is preferably a laser pen, the calibration part 5 is installed in the middle of one inner side of the column 22, and the aforementioned top connecting plate 23, two columns 22 and the clamping bottom plate 21 together form a clamping frame body. When the calibration part 5 works, the ray will be emitted behind the other column 22 and vertically extend up and down along the other column 22, forming a calibration light circle in the clamping frame body. Each scraping blade 333h performs alignment calibration according to the projection position of the calibration light circle, so that the blade edge coincides with the calibration light circle to ensure the accuracy of the acting position of the scraping blade 333h.

[0043] Before use, first, as described above, assemble the film 71 on the tensioning mechanism 32 of the ink vertical leveling unit 3, and cooperate with the tension constant mechanism 34 to provide a preset tension for the film 71. During use, first clamp the product to be leveled with ink as described above, then perform ink printing on the surface of the product to be leveled with ink. Next, the horizontal conveying linear module 4 drives the clamping and conveying unit 2 to feed towards the ink vertical leveling unit 3 through the bottom slider 211. Subsequently, the vertical leveling mechanism 33 pushes the leveling knife group 333 towards the film 71 through the leveling cylinder 332, so that the scraper 333h of the leveling knife group 333 presses the film 71 to contact the surface of the product to be leveled with ink. During the process of the scraper 333h pressing the film 71, the tension cylinder 342 of the tension constant mechanism 34 drives the tension roller 345 to retreat, canceling the pressure on the film 71. Then, the running table linear module 316 of the double-head carrying mechanism 31 displaces according to the width of the product to be leveled with ink, driving the tensioning mechanism 32 and the vertical leveling mechanism 33 to feed towards the clamping workbench 11 together, and leveling the ink on the surface of the product to be leveled with ink. After leveling, the leveling cylinder 332 of the leveling knife group 333 drives the scraper 333h of the leveling knife group 333 to reset. At the same time as the scraper 333h of the leveling knife group 333 resets, the tension cylinder 342 of the tension constant mechanism 34 resets the tension roller 345, pressing the film 71 to make the tension received by the film 71 before and after the leveling operation consistent. Subsequently, the tensioning mechanism 32 and the vertical leveling mechanism 33 reset along with the running table linear module 316 of the double-head carrying mechanism 31. At the same time, the horizontal conveying linear module 4 drives the clamping and conveying unit 2 to reset, so that the user can remove the product that has completed ink leveling and replace it with the next product to be leveled with ink, and repeat the ink leveling operation for the product to be leveled with ink as described above. It should be noted here that when the sizes of the products for ink leveling operations are the same, the clamping and conveying unit 2 in the clamping area can be directly adjusted using the previous product to be leveled with ink for product clamping, without secondary adjustment.

[0044] It should be noted that the consistent tension received by the film 71 before and after the ink leveling operation is used to provide a tension detection for the brake 322 of the unwinding air shaft roller group 321. When the brake 322 fails to detect the preset tension, the equipment operation will be paused and the user will be reminded to replace the coil 7.

[0045] In addition, as Figure 12As shown, in order to prevent interference from dust and the like during the ink leveling operation and affect the yield of the product, a dust-proof bracket 6 composed of several aluminum profiles is also provided on the frame 1. At least one door frame is provided on each of the front and back sides of the dust-proof bracket 6 at the position of the leveling workbench 12. A dust-proof door 61 is hinged on each door frame. The other positions of the dust-proof bracket 6 are closed by dust-proof plates 62. Only a clamping opening (not shown) is left on one side of the dust-proof bracket 6 at one end of the clamping workbench 11 for the operator to load and unload the product. The setting of the dust-proof door 61 can not only effectively cooperate with other dust-proof plates 62 to form a relatively enclosed working space in the area of the leveling workbench 12, but also facilitate the operator's maintenance. At least one door frame inside at least one of the dust-proof doors 61 is also provided with at least one access control (not shown). This access control is preferably a travel switch. When the present invention is working, if the dust-proof door 61 is accidentally opened, the present invention will immediately stop working and alarm to remind the user. A conveying opening (not shown) is reserved between the leveling workbench 12 and the clamping workbench 11 on the dust-proof bracket 6. This conveying opening facilitates the reciprocating displacement of the clamping and conveying unit 2 between the leveling workbench 12 and the clamping workbench 11. An alarm lamp 63 is also provided on one of the dust-proof plates 62 on the top surface of the dust-proof bracket 6. This alarm lamp 63 is electrically connected to the control console. When the present invention needs to give an alarm, this alarm lamp 63 will light up accordingly to remind the user.
