Description

Technical Field

[0001] The present invention relates to the technical field of film laminating devices, and particularly to a film laminating machine and its dry film adsorption mechanism. Background Art

[0002] In the field of printed circuit board (PCB) manufacturing, as a core device, the function stability of the MSAP film laminating machine directly affects the lamination accuracy and yield rate between the dry film and the substrate. In the prior art, the film laminating machine realizes the positioning and fixing of the dry film through a vacuum adsorption system, but there are the following technical defects: the existing equipment adopts a structural design of directly connecting multiple air pipes to the guiding block, lacking a real-time air pressure monitoring and feedback mechanism, resulting in uneven suction force distribution in each air path and unable to be accurately adjusted. When the suction force exceeds the process tolerance range, it is easy to cause local deviation or insufficient lamination of the dry film, resulting in line pattern distortion or film layer bubble residue. The design of sharing a single vacuum source for the cutter slot and the guiding block leads to the forced linkage of their adsorption functions and cannot be independently started and stopped according to the process requirements. For example, when it is necessary to turn off the adsorption of the guiding block during the cutting stage, the cutter slot simultaneously loses the vacuum suction force, resulting in wrinkles or tears of the dry film due to local tension imbalance at the moment of cutting, directly affecting the graphic integrity of the subsequent etching process. The frequent occurrence of such failures not only increases the rework rate but also significantly restricts the continuous production efficiency of the equipment. Summary of the Invention

[0003] The purpose of the present invention is to provide a film laminating machine and its dry film adsorption mechanism, which separates the vacuum pipelines of the guiding block and the cutter slot and controls them by different solenoid valves, significantly reducing the suction force fluctuation caused by the parallel connection of multiple air paths, reducing the rework rate and failure rate, and improving the yield rate of the film laminating products.

[0004] To achieve the above purpose, the present invention provides a dry film adsorption mechanism for a film laminating machine, including:

[0005] A first vacuum tank;

[0006] A film laminating plate, which is communicated with the first vacuum tank, and the film laminating plate is connected to the first vacuum tank through a first air pipe group;

[0011] Among them, solenoid valves are provided on the first air pipe group, the second air pipe group, and the third air pipe group.

[0012] Compared with the prior art, the dry film adsorption mechanism of the film laminating machine in the embodiment of the present invention has the beneficial effects that: when using this device, turn on the blower, suck the first vacuum tank through the vacuum cell, and then the employee pastes the dry film on the film laminating disk. The dry film moves along the guiding groove, and the cutting knife cuts the dry film. At this time, if the air pressure deviates from the normal range, only need to adjust the solenoid valve of the corresponding air pipe, then the vacuum degree at each component can be adjusted. By setting the hierarchical vacuum system of the first vacuum tank and the second vacuum tank, the adsorption air paths of the cutting knife groove and the guiding block are completely decoupled. Cooperating with the solenoid valves on each air pipe group, the adsorption functions of the film laminating disk, the cutting knife groove and the guiding block can be independently controlled in sequence. By separating the vacuum pipelines of the guiding block and the cutting knife groove and controlling them by different solenoid valves, it is not necessary to simultaneously adsorb and turn on and off as before, significantly reducing the suction force fluctuation caused by the parallel connection of multiple air paths, reducing the rework rate and failure rate, and improving the yield of the film laminating product.

[0030] As Figure 1 shown, a dry film adsorption mechanism of a film laminating machine according to a preferred embodiment of the present invention includes a first vacuum tank 1 fixed to the main body of the film laminating machine, a film laminating disk 2, a cutter groove 3, a second vacuum tank 4, a guiding block 5, vacuum cells, and a blower. The above components are fixed to the main body of the film laminating machine by means of bolts or the like;

[0031] Among them, the film pasting disc 2 is arranged in parallel with the first vacuum groove 1. Its function is to drive the dry film to be pasted downwards during film pasting until the head of the dry film is closely attached to the head of the PCB board and then it returns to its original position. The film pasting disc 2 is communicated with the first vacuum groove 1, and the film pasting disc 2 and the first vacuum groove 1 are connected by a first air pipe group 11; the cutter groove 3 is arranged at intervals below the film pasting disc 2, and the cutter groove 3 is also communicated with the first vacuum groove 1. The cutter groove 3 and the first vacuum groove 1 are connected by a second air pipe group 12. A large number of air holes are distributed on the cutter groove 3 to adsorb the dry film. When the dry film is about to reach the cutter groove 3, the adsorption of the cutter groove 3 is turned on, and the cutter in the cutter groove 3 moves along the cutter groove 3 to cut the dry film; the second vacuum groove 4 is communicated with the first vacuum groove 1, and the second vacuum groove 4 is arranged below the first vacuum groove 1; the guiding block 5 is arranged at intervals below the cutter groove 3, and a plurality of rows of air holes are neatly distributed thereon to balance the adsorption of the dry film. The guiding block 5 is communicated with the second vacuum groove 4, and the guiding block 5 and the second vacuum groove 4 are connected by a third air pipe group 41. By setting the hierarchical vacuum system of the first vacuum groove 1 and the second vacuum groove 4, the adsorption air paths of the cutter groove 3 and the guiding block 5 are completely decoupled; the vacuum cell is communicated with the first vacuum groove 1 to provide vacuum degree for the first vacuum groove 1, and the vacuum cell is also connected with a blower; among them, electromagnetic valves 6 are arranged on the first air pipe group 11, the second air pipe group 12 and the third air pipe group 41. The electromagnetic valve 6 can control the on-off of the first air pipe group, the second air pipe group 12 and the third air pipe group 41 and adjust the flow rates of the first air pipe group, the second air pipe group 12 and the third air pipe group 41.

[0032] When using this device, turn on the blower, suck the first vacuum groove 1 through the vacuum cell, and then the employee pastes the dry film on the film pasting disc 2. The dry film moves along the guiding groove, and the cutter cuts the dry film. At this time, if the air pressure deviates from the normal range, just adjust the electromagnetic valve 6 of the corresponding air pipe to adjust the vacuum degree at each component. By setting the hierarchical vacuum system of the first vacuum groove 1 and the second vacuum groove 4, the adsorption air paths of the cutter groove 3 and the guiding block 5 are completely decoupled. Cooperating with the electromagnetic valves 6 on each air pipe group, the adsorption functions of the film pasting disc 2, the cutter groove 3 and the guiding block 5 can be independently controlled in sequence. By separating the vacuum pipelines of the guiding block 5 and the cutter groove 3 and controlling them by different electromagnetic valves 6, it is not necessary to adsorb and turn on and off simultaneously as before, significantly reducing the suction force fluctuation caused by the parallel connection of multiple air paths, reducing the rework rate and failure rate, and improving the yield of the film pasting product.

[0033] In some embodiments of the present invention, the interior of the first vacuum chamber 1 is divided into six compartments. Four of them are used to connect to the film - sticking disc 2, one is connected to the cutter groove 3, and one is connected to the second vacuum chamber 4. In the prior art, the vacuum chamber is generally divided into five compartments, where four are used to connect to the film - sticking disc 2, and the cutter groove 3 and the guiding block 5 share one compartment. The first vacuum chamber 1 of the present application is provided with six compartments, four of which are connected to the film - sticking disc 2, one is connected to the cutter groove 3, and one is connected to the guiding block 5 through the second vacuum chamber 4, realizing the separation of the adsorption circuits between the cutter groove 3 and the guiding block 5, without simultaneously adsorbing and turning on / off as before, thus improving the yield of the film - sticking products.

[0034] In some embodiments of the present invention, negative - pressure gauges 7 are provided on the first air - pipe group 11, the second air - pipe group 12, and the third air - pipe group 41. The negative - pressure gauges 7 are used to display the adsorption conditions at each air - pipe group. The negative - pressure gauges 7 will show the air - pressure magnitudes of each air - pipe group. If the air - pressure deviates from the normal range, only the solenoid valve 6 of the corresponding air - pipe needs to be adjusted to make the reading of the negative - pressure gauge 7 return to the normal range. This is convenient for the staff to observe the vacuum - pumping conditions of each air - pipe group and adjust the solenoid valves 6 of each air - pipe group correspondingly through the readings.

[0035] In some embodiments of the present invention, the vacuum compartments include a first vacuum compartment 81 and a second vacuum compartment 82. The first vacuum compartment 81 is connected to a first blower 9 to evacuate the film - sticking disc 2, and the second vacuum compartment 82 is connected to a second blower 10 to evacuate the guiding block 5 and the cutter groove 3. Among them, the first vacuum compartment 81 is connected to the upper four - compartment space of the first vacuum chamber 1, and the second vacuum compartment 82 is connected to the lower two - compartment space of the first vacuum chamber 1. The setting of the double - vacuum compartments enables the first vacuum chamber 1 and the second vacuum chamber 4 to set the vacuum degrees respectively, which is beneficial to adjusting the adsorption forces required by different components; moreover, it has a fault - isolation mechanism, ensuring the separation of the cutting groove and the film - sticking disc 2. When the adsorption of the cutting groove fails, the cutter groove 3 can still maintain vacuum adsorption to complete the current cutting cycle.

[0036] In some embodiments of the present invention, a fourth air - pipe group 13 is provided on the first vacuum compartment 81. The fourth air - pipe group 13 includes a first vacuum - chamber air - pipe 131 connecting to the first vacuum chamber 1 and a first external air - inlet pipe 132 connecting to the atmosphere. The first vacuum - chamber air - pipe 131 is used to evacuate the first vacuum chamber 1, and the first external air - inlet pipe 132 is used for the first blower 9 to inhale air through the first external air - inlet pipe 132 of the first vacuum compartment 81 when the film - sticking disc 2 does not require adsorption force.

[0037] In some embodiments of the present invention, solenoid valves 6 are provided on both the first vacuum tank air pipe 131 and the first external air inlet pipe 132. The first external air inlet pipe 132 is further connected to a primary filter 133, which is threadedly connected to the first external air inlet pipe 132 and can filter and purify the inhaled gas. The solenoid valve 6 can achieve millisecond-level timing control of the first vacuum tank air pipe 131 to avoid film material wrinkles caused by synchronous pressure cut-off during cutting. When the laminating disc 2 does not require adsorption force, the solenoid valve 6 on the first external air inlet pipe 132 receives a signal and opens. At this time, the first blower 9 inhales air through the first external air inlet pipe 132 of the first vacuum cell 81. When the laminating disc 2 requires adsorption force, the solenoid valve 6 of the first vacuum tank air pipe 131 opens, and the solenoid valve 6 of the first external air inlet pipe 132 closes. The adsorption force generated by the blower travels along the connected pipes to the guiding block 5, and the dry film is stably adsorbed until the dry film is completely attached to the PCB board.

[0038] In some embodiments of the present invention, a fifth air pipe group 14 is provided on the second vacuum cell 82. The fifth air pipe group 14 includes a second vacuum tank air pipe 141 connecting the first vacuum tank 1 and a second external air inlet pipe 142 connecting to the atmosphere. The second vacuum tank air pipe 141 is used to evacuate the second vacuum tank 4, and the second external air inlet pipe 142 is used for the second blower 10 to inhale air through the second external air inlet pipe 142 of the second vacuum cell 82 when the laminating disc 2 does not require adsorption force.

[0039] In some embodiments of the present invention, solenoid valves 6 are provided on both the second vacuum tank air pipe 141 and the second external air inlet pipe 142. The second external air inlet pipe 142 is further connected to a primary filter 133, which is threadedly connected to the first external air inlet pipe 132 and can filter and purify the inhaled gas. The solenoid valve 6 can achieve millisecond-level timing control of the second vacuum tank air pipe 141 to avoid film material wrinkles caused by synchronous pressure cut-off during cutting. When the laminating disc 2 does not require adsorption force, the solenoid valve 6 on the second external air inlet pipe 142 receives a signal and opens. At this time, the second blower 10 inhales air through the second external air inlet pipe 142 of the second vacuum cell 82. When the laminating disc 2 requires adsorption force, the solenoid valve 6 of the second vacuum tank air pipe 141 opens, and the solenoid valve 6 of the second external air inlet pipe 142 closes. The adsorption force generated by the blower travels along the connected pipes to the guiding block 5, and the dry film is stably adsorbed until the dry film is completely attached to the PCB board.

[0040] In some embodiments of the present invention, a vacuum tube 91 connecting the vacuum cell and an exhaust pipe 92 connecting to the outside are provided on the blower. The vacuum tube 91 is used to generate an adsorption force for the first vacuum chamber 1, and the exhaust pipe 92 is used to discharge gas. When the blower operates, it will suck air through the vacuum tube 91, thereby providing an adsorption force for the first vacuum chamber 1, and then discharging the gas through the exhaust pipe 92 to complete the cycle.

[0041] The present invention also provides a film laminating machine, which includes a film laminating machine main body and the dry film adsorption structure of the film laminating machine according to any one of the above embodiments. The first vacuum chamber 1, the film laminating plate 2, the cutter groove 3, the second vacuum chamber 4, the guiding block 5, the vacuum cell, and the blower are all fixed on the film laminating machine main body. The adsorption gas paths of the cutter groove 3 and the guiding block 5 are completely decoupled through the dry film adsorption structure. In cooperation with the electromagnetic valves 6 on each air pipe group, the adsorption functions of the film laminating plate 2, the cutter groove 3, and the guiding block 5 can be independently controlled in sequence. By separating the vacuum tube 91 paths of the guiding block 5 and the cutter groove 3 and controlling them by different electromagnetic valves 6, it is not necessary to simultaneously adsorb and open / close as before, significantly reducing the suction force fluctuation caused by the parallel connection of multiple air paths, reducing the rework rate and failure rate, and improving the yield rate of the film laminated products.

[0042] The working process of the present invention is as follows: When using this device, turn on the blower, suck the first vacuum chamber 1 through the vacuum cell, and then an employee pastes the dry film on the film laminating plate 2. The dry film moves along the guiding groove, and the cutter cuts the dry film. At this time, if the air pressure deviates from the normal range, just adjust the electromagnetic valve 6 of the corresponding air pipe to adjust the vacuum degree at each component.

[0043] In summary, the embodiments of the present invention provide a film laminating machine and its dry film adsorption mechanism. By setting a hierarchical vacuum system for the first vacuum chamber 1 and the second vacuum chamber 4, the adsorption gas paths of the cutter groove 3 and the guiding block 5 are completely decoupled; in cooperation with the electromagnetic valves 6 on each air pipe group, the adsorption functions of the film laminating plate 2, the cutter groove 3, and the guiding block 5 can be independently controlled in sequence. By separating the vacuum pipelines of the guiding block 5 and the cutter groove 3 and controlling them by different electromagnetic valves 6, it is not necessary to simultaneously adsorb and open / close as before, significantly reducing the suction force fluctuation caused by the parallel connection of multiple air paths, reducing the rework rate and failure rate, and improving the yield rate of the film laminated products.

[0044] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present invention.
