Description

Technical Field

[0001] This invention relates to the field of PCB board-based film application technology, specifically a film application process based on a fully automatic film application machine. Background Technology

[0002] MEMS chip packaging differs from traditional frame-type packaging. It is applied to the PCB board. The processed products are divided into front-facing and back-facing microphones in terms of structure. Since MEMS chips have very high sensitivity requirements, in order to avoid particles being introduced during processing at each packaging site and affecting product quality, a high-temperature film is required before mounting (back-facing microphone). The traditional film application method is to apply the film manually, which increases labor costs, increases labor intensity, and also significantly affects production efficiency.

[0003] Manual film application carries the risk of misalignment; when triggering the flattening action, the hand touches the inside of the PCB board, and if the gloves retain sweat or other foreign matter, there is a risk of contamination and oxidation. Each product in each batch requires manual film application, increasing the risk of foreign matter. The main source of this risk is the cleanliness of the gloves; airborne particles can also leach into them (each film application involves spreading over 200cm in length before placing each strip on the PCB board, increasing the risk of foreign matter).

[0004] Traditionally, the film is applied manually. According to historical daily film application data, 30-120 batches of film can be applied every day, which means 600-2400 PCB boards need to be filmed. In order to ensure quality and quantity, this will increase labor costs (1-2 people are needed to complete the work every day).

[0005] For example, Chinese Patent CN 115003052 A discloses a method for manufacturing a flexible circuit board and a flexible circuit board, which includes the following steps: S1. Cutting a polymer film; S2. Laying copper sheets; S3. Processing the circuit board; S4. Cleaning the circuit board; S5. Covering with an insulating film; S6. Stamping and forming;

[0006] In the aforementioned patent, manual positioning of the circuit board is still required when bonding the film. Due to the low accuracy and efficiency of manual positioning, the efficiency of bonding the circuit board film is low and the yield is poor.

[0007] Therefore, there is a need for a film application process that can improve the efficiency and quality of film application on PCB boards. Summary of the Invention

[0008] The purpose of this invention is to provide a film application process based on a fully automatic film application machine, so as to solve the technical problems mentioned in the background art, such as low efficiency and easy misalignment of traditional manual film application, which affect the efficiency and quality of film application.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] A film application process based on a fully automatic film applicator, the film application process comprising the following steps:

[0011] Step 1: Place the product to be coated into the slot of the plate feeding mechanism;

[0012] Step 2: Start the plate feeding mechanism, which will sequentially transport the products to be coated to the positioning area;

[0013] Step 3: Activate the positioning mechanism to position the product to be coated in the positioning area;

[0014] Step 4: The plate feeding mechanism transports the positioned product to be coated to the coating area;

[0015] Step 5: The film feeding mechanism is activated to deliver the adhesive film to the top of the product to be coated in the film application area;

[0016] Step 6: Start the film application device. The film application device presses the adhesive film onto the surface of the product to be filmed, and the filmed product is obtained.

[0017] Step 7: The film-coated product is removed from the slot and placed in the finished product area by the conveying device, and the plate feeding mechanism is reset.

[0018] Preferably, in step 3, when the positioning mechanism is started, it positions the product to be coated in the Y-axis direction and the Z-axis direction respectively, so that the edge of the product to be coated is parallel to the edge of the adhesive film.

[0019] Preferably, in step 4, when the plate feeding mechanism delivers the product to be coated after positioning, the plate feeding mechanism moves horizontally to the coating area, so that the edge of the product to be coated on the surface of the plate feeding mechanism coincides with the edge projection of the adhesive film.

[0020] Preferably, in step 5, the film feeding mechanism is started, and the film pulling device of the film feeding mechanism pulls out the film material. The film material is composed of a backing film with a release liner. When the film material passes through the peeling device, the release liner on one side of the backing film is peeled off. When the backing film enters the film application area, the two sides of the backing film are flush with the edges of the product to be applied, so that the projection of the backing film above the product to be applied coincides with the product to be applied.

[0021] Preferably, in step 6, when the film applicator is started, the rollers of the film applicator begin to roll from the surface of the adhesive film, rolling from one end of the product to be applicated to the other end, so that the adhesive film is applied to the surface of the product.

[0022] Preferably, in step 5, when the film feeding mechanism is started, the release film is pulled, and the adhesive film is pushed into the film application area by the adhesive film on the rear side when it passes the peeling device.

[0023] After the film is applied, the cutting device cuts the end of the adhesive film away from the application area.

[0024] Preferably, the feeding mechanism includes a feeding slot and a first plug lifting device. The feeding slot is located at one end of the feeding track, and the other end of the feeding track is close to the film application area. The first plug lifting device is located on one side of the feeding slot. The first plug lifting device is used to lift the product to be applied in the feeding slot and place it into the feeding track. The feeding track is used to transport the product to be applied near the feeding slot to the area close to the film application area.

[0025] Preferably, the feeding mechanism further includes a translation device, which is disposed on the upper part of the feeding track near the film application area. The translation device includes a translation track and a suction cup. The suction cup is disposed at both ends of the translation track and slides on the bottom surface of the translation track. One end of the translation track is disposed on the upper part of the feeding track, and the other end is disposed on the upper part of the unloading track.

[0026] Preferably, the unloading track and the feeding track are spaced apart and parallel to each other, and the feeding track, unloading track and translation track form a U-shaped structure, with the film-applying area located at the lower part of the bottom of the U-shaped structure.

[0027] Preferably, the end of the unloading track away from the translation track is provided with a second stopper lifting device and an unloading slot. The second stopper lifting device is used to transport the product after the film has been applied to the surface of the unloading slide rail into the unloading slot.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] This invention provides a film application process based on a fully automatic film application machine, the film application process comprising the following steps:

[0030] Step 1: Place the product to be coated into the slot of the plate feeding mechanism;

[0031] Step 2: Start the plate feeding mechanism, which will sequentially transport the products to be coated to the positioning area;

[0032] Step 3: Activate the positioning mechanism to position the product to be coated in the positioning area;

[0033] Step 4: The plate feeding mechanism transports the positioned product to be coated to the coating area;

[0034] Step 5: The film feeding mechanism is activated to deliver the adhesive film to the top of the product to be coated in the film application area;

[0035] Step 6: Start the film application device. The film application device presses the adhesive film onto the surface of the product to be filmed, and the filmed product is obtained.

[0036] Step 7: The film-coated product is removed from the slot and placed in the finished product area using the conveying device, and the plate feeding mechanism is reset;

[0037] When the laminating machine is working, the operator places the product to be laminated into the slot and installs the roll of high-temperature film on the laminating machine. The feeding mechanism moves the products to be laminated one by one from the slot to the bottom of the positioning device. After the positioning device is activated, it positions the products to be laminated on the surface of the feeding mechanism. After positioning, the feeding mechanism moves the positioned products to the laminating area to wait for lamination. At the same time, the film feeding mechanism pulls the film material, so that the film material enters the laminating area and is finally positioned above the products to be laminated. The laminating device rolls the film material to adhere it to the products to be laminated, resulting in laminated products. The transport device transfers the laminated products to the finished product area, the feeding mechanism resets, and the next product to be laminated is transported for lamination.

[0038] This method solves the problems of high labor costs, low material feeding efficiency, and large differences in product film application results caused by traditional manual film application. The automated film application method can save labor costs, reduce manual labor intensity, and improve film application efficiency and quality. Attached Figure Description

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0051] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Example 1

[0052] Please see Figure 1-5A film application process based on a fully automatic film applicator, the film application process including the following steps:

[0053] Step 1: Place the product to be coated into the slot of the plate feeding mechanism;

[0054] Step 2: Start the plate feeding mechanism, which will sequentially transport the products to be coated to the positioning area;

[0055] Step 3: Activate the positioning mechanism to position the product to be coated in the positioning area;

[0056] Step 4: The plate feeding mechanism transports the positioned product to be coated to the coating area 3;

[0057] Step 5: The film feeding mechanism is activated to deliver the adhesive film to the top of the product to be coated in the film application area 3;

[0058] Step 6: Start the film application device. The film application device presses the adhesive film onto the surface of the product to be filmed, and the filmed product is obtained.

[0059] Step 7: The film-coated product is removed from the slot and placed in the finished product area by the plate handling device, and the plate feeding mechanism is reset.

[0060] In the above embodiments, when the laminating machine is working, the operator places the product to be laminated into the slot and installs the roll of high-temperature film on the laminating machine. The feeding mechanism transports the products to be laminated in the slot one by one to the bottom of the positioning device. After the positioning device is activated, it positions the products to be laminated on the surface of the feeding mechanism. After positioning, the feeding mechanism moves the positioned products to be laminated to the laminating area 3 to wait for lamination. At the same time, the feeding mechanism pulls the film material so that it enters the laminating area 3 and is finally positioned above the products to be laminated. The laminating device rolls the film material so that it is pasted onto the products to be laminated, resulting in a laminated product. The transport device transfers the laminated product to the finished product area. The feeding mechanism resets and transports the next product to be laminated for lamination.

[0061] This method solves the problems of high workload, low material dispensing efficiency, and large differences in product film application results caused by traditional manual film application. The automatic film application method can save labor costs, reduce manual labor intensity, and improve film application efficiency and quality. Example 2

[0062] Please see Figure 1-5 In step 3, when the positioning mechanism is started, it positions the product to be coated in the Y-axis and Z-axis directions respectively, so that the edge of the product to be coated is parallel to the edge of the adhesive film.

[0063] In the above embodiments, the positioning mechanism is used in the Y-axis and Z-axis directions of the product to be coated. When the positioning mechanism is working, the product to be coated is placed on the surface of the positioning mechanism by a vacuum suction cup. The positioning mechanism pushes the product to be coated in the Y-axis and Z-axis directions by a pushing device, so that the Y-axis side and Z-axis side of the product to be coated abut against the limiting plate of the positioning mechanism, thereby realizing the positioning function of the positioning mechanism for the product to be coated. This ensures that the product to be coated coincides with the film material when the film is applied, avoiding the problem of misalignment. Example 3

[0064] Please see Figure 1-5 In step 4, when the board feeding mechanism delivers the product to be coated after positioning, the board feeding mechanism moves horizontally to the coating area 3, so that the edge of the product to be coated on the surface of the board feeding mechanism coincides with the edge projection of the adhesive film.

[0065] In the above embodiments, after the product to be coated is positioned by the positioning mechanism, the plate feeding mechanism horizontally moves the product to be coated to the coating area, so that the coating area can apply film to the product to be coated. This is to smoothly move the positioned product to be coated to the coating area, so as to avoid the product to be coated from moving during transportation after positioning, which would cause misalignment between the film material and the product to be coated during the coating process. Example 4

[0066] Please see Figure 1-5 In step 5, the film feeding mechanism is started, and the film pulling device of the film feeding mechanism pulls out the film material. The film material is composed of a backing film with a release liner. When the film material passes through the peeling device, the release liner on one side of the backing film is peeled off. When the backing film enters the film application area 3, the two sides of the backing film are flush with the edges of the product to be applied, and the projection of the backing film above the product to be applied coincides with the product to be applied.

[0067] In the above embodiments, when the film feeding mechanism is started, the film pulling device pulls one end of the release film, so that the film material passes through the peeling device when it moves. When the film material passes through the peeling device, the adhesive film with the release film enters the film application area. The release film is pulled by the film pulling device, so that the release film is continuously rolled up, realizing the automatic output of the adhesive film and the automatic winding function of the release film. Example 5

[0068] Please see Figure 1-5 In step 6, when the film applicator is started, the rollers of the film applicator begin to roll from the surface of the adhesive film, rolling from one end of the product to be applicated to the other end, so that the adhesive film is applied to the surface of the product.

[0069] In the above embodiments, when the film applicator is started, the rollers of the film applicator roll and press the surface of the adhesive film, so that the adhesive film is attached to the product to be applicated, thereby realizing the automatic film applicator function. Example 6

[0070] Please see Figure 1-5 In step 5, when the film feeding mechanism is started, the release film is pulled and the adhesive film is pushed into the film application area 3 by the back adhesive film when it passes the peeling device.

[0071] After the film is applied, the cutting device cuts the end of the adhesive film away from the film application area 3.

[0072] In the above embodiments, after the film-applying device completes the film application, the cutting device operates to cut the side of the adhesive film away from the film-applying area, so that the size of the adhesive film is slightly larger than the size of the film-applying product. Example 7

[0073] Please see Figure 1-5 The feeding mechanism includes a feeding slot 1 and a first plug lifting device 2. The feeding slot 1 is located at one end of the feeding track 4, and the other end of the feeding track 4 is close to the film application area 3. The first plug lifting device 2 is located on one side of the feeding slot 1. The first plug lifting device 2 is used to lift the product to be applied in the feeding slot 1 and place it into the feeding track 4. The feeding track 4 is used to transport the product to be applied near the feeding slot 1 to the area close to the film application area 3.

[0074] In the above embodiments, when the feeding mechanism is started, the first chuck lifting device is activated to grab and lift the product to be coated in the feeding slot. Then, the first chuck lifting device places the product to be coated on the feeding track. The feeding track transports the product to be coated from the side near the feeding slot to the side near the coating area, realizing the functions of automatic feeding and transportation. Example 8

[0075] Please see Figure 1-5 The feeding mechanism also includes a translation device, which is located on the upper part of the feeding track 4 near the film application area 3. The translation device includes a translation track 5 and a suction cup 6. The suction cup 6 is located at both ends of the translation track 5 and slides on the bottom surface of the translation track 5. One end of the translation track 5 is located on the upper part of the feeding track 4, and the other end is located on the upper part of the unloading track 7.

[0076] In the above embodiment, when the feeding track transports the product to be coated to the vicinity of the coating area, the suction cup of the translation device is activated to pick up the product to be coated on the feeding track. Then, the product to be coated is moved to the positioning mechanism. After the positioning mechanism positions the product to be coated, it moves to the coating area to apply the coating. After the coating is completed, the suction cup at the other end of the translation device picks up the product and places it on the unloading track. The unloading track transports the product from the side near the coating area to the unloading slot. The second clamp lifting device grabs the product and places it in the unloading slot, thus realizing the functions of automatically transporting the product to be coated and recycling the coated product. Example 9

[0077] Please see Figure 1-5 The unloading track 7 and the feeding track 7 are spaced apart and parallel to each other. The feeding track, the unloading track 7 and the translation track 5 form a U-shaped structure. The film application area 3 is located at the bottom of the U-shaped structure.

[0078] In the above embodiments, the unloading track and the feeding track are arranged in parallel, which allows for quick and convenient movement of the product to be coated when the suction cup on the translation track is used to transport it. The positioning mechanism is set between the feeding track and the unloading track. Another translation slide rail can be set below the positioning mechanism so that the positioning mechanism can be translated to the coating area, protecting the position of the product to be coated after positioning from being affected by the transportation. Example 10

[0079] Please see Figure 1-5 The end of the feeding track 7 away from the translation track 5 is provided with a second stopper lifting device 8 and a feeding slot 9. The second stopper lifting device 8 is used to transport the product after the film is applied to the surface of the feeding slide rail into the feeding slot 9.

[0080] In the above embodiment, the second clamp lifting device cooperates with the unloading slot. The second clamp device is used to grab the film-coated products on the unloading track and place them in the unloading slot for collection. Example 11

[0081] Please see Figure 1-3 The feeding track includes two spaced-apart vertical plates 10, which are arranged in parallel. Each of the two vertical plates 10 has a pulley assembly 11 on its adjacent surface. The two ends of the pulley assembly 11 are respectively located on both sides of the vertical plate 10. The pulley assembly 11 is located on the upper side of the surface of the vertical plate 10. The two pulley assemblies 11 cooperate to support the bottom surface of the product to be coated. The product to be coated is placed between the two vertical plates 10. The pulley assembly 11 is connected to a drive motor 12, which is installed on the outer wall of the vertical plate 10. The drive motor 12 is used to drive the two pulley assemblies 11.

[0082] The lower part of the two upright plates 10 is set on the surface of the bracket 13.

[0083] In the above embodiment, the feeding track and the unloading track have the same structure, and the drive motor 12 rotates in opposite directions. When the feeding track is started, the first clamp lifting device places the product to be coated between the two upright plates 10. The product to be coated is placed on the surface of the pulley assembly 11 between the two upright plates 10. After the drive motor 12 is started, it drives the two pulley assemblies 11 to work. When the pulley assembly 11 works, it moves the product to be coated from one side to the other side. The pulley assembly 11 is used to transport the product to be coated or the coated product after coating. Example 12

[0084] Please see Figure 1-9 The translational track delivers the positioning mechanism and the product to be coated to the coating area. The positioning mechanism also includes a sleeve 18, with an elliptical groove 19 provided along the inner wall of the sleeve 18. The centerline of the sleeve 18 passes through the center of the elliptical groove 19. Two sliders 20 are slidably disposed within the elliptical groove 19. The two sliders 20 are respectively connected to the mounting ends of a first gripper 21 and a second gripper 22. The two sliders 20 are respectively disposed at both ends of the elliptical groove 19. The ends of the first gripper 21 and the second gripper 22 furthest from the mounting end are disposed at one end outside the sleeve 18. The sleeve 18 is further... A rotary motor 23 is provided at one end. The output shaft of the rotary motor 23 is located inside the sleeve 18. The output shaft of the rotary motor 23 is provided with a first rotating plate 24. The surface of the first rotating plate 24 is provided with two through holes. The first gripper 21 and the second gripper 22 are respectively provided through the through holes. The first gripper 21 and the second gripper 22 are also provided through a second rotating plate 25. The first gripper 21 and the second gripper 22 are respectively located on both sides of the center of the second rotating plate 25. The first gripper 21 and the second gripper 22 cooperate to drive the second rotating plate 25 to rotate around the center line of the sleeve 18.

[0085] The adjacent surfaces of the first gripper 21 and the second gripper 22 are provided with gripper suction cups.

[0086] In the above embodiments, after the positioning mechanism positions the product to be coated, the first gripper 21 and the second gripper 22 use gripper suction cups to adsorb and grip both sides of the product to be coated. When applying the film, the first gripper 21 is above the product to be coated and is located at the uppermost part of the horizontally set sleeve 18. The second gripper 22 is located at the lowermost part of the sleeve 18. Affected by the elliptical groove 19, the slider 20 connected to the second gripper 22 is located at the lowest point of the elliptical groove 19 and is close to the product to be coated. Conversely, the slider 20 connected to the first gripper 21 is located at the highest point of the elliptical groove 19 and is far away from the product to be coated. The gripper suction cup of the first gripper 21 stops adsorbing during the recycling process, while the second gripper 22 continues to adsorb and support the product to be coated.

[0087] When applying the first surface film to the product to be filmed, the first gripper 21 retracts, completely exposing the surface of the product to be filmed, while the second gripper 22 supports the product to be filmed during the application process.

[0088] Conversely, when the first gripper 21 and the second gripper 22 are driven by the rotary motor 23, the first rotating plate rotates, causing the first gripper 21 and the second gripper 22 to rotate around the center line of the sleeve 18. When the two sliders 20 slide in the elliptical groove 19, the first gripper 21 moves from the highest point to the lowest point of the elliptical groove 19. Since the elliptical groove 19 is inclined relative to the center line of the sleeve 18, the first gripper 21 will enter the first surface of the product to be coated from one side of the product to be coated when the product is flipped. When the product to be coated is rotated, the first surface is coated and gradually flipped. The second gripper 22 gradually moves out from the second surface of the product to be coated, so that the second surface of the product to be coated is completely facing upward. At this time, the second gripper 22 completely leaves the product to be coated.

[0089] At this point, the second surface of the product to be coated is coated. Due to the influence of the storage environment, when PCB products are stored in harsh environments, the circuit surface of the PCB board must be coated, and the other side also needs to be coated to prevent the other side from being corroded.

[0090] This device automatically flips the product to be laminated, and the grippers can move away from the surface to be laminated during the lamination process, making it easier to apply the film. At the same time, the two grippers can automatically extend and retract through the elliptical slide 19. When they are at different heights, they can adsorb and support the bottom surface of the PCB board. The flipping efficiency is high, and it does not affect the normal lamination of the lamination equipment.

[0091] Meanwhile, when the second rotating plate 25 rotates, it can also drive the reciprocating mechanism to work. One end of the reciprocating mechanism is used to connect to the dust removal device, and the other end is used to connect to the cutting device. The automatic flipping device can not only complete the flipping, but also automatically clean the film surface of the product to be laminated, and can also realize the automatic cutting of the film material. This effectively saves the size of the laminating machine, makes higher space utilization, requires fewer drive devices, is more environmentally friendly, and has higher operating efficiency. Example 13

[0092] Please see Figure 1-9 The second rotating plate 25 is used to drive a reciprocating mechanism, which includes a reciprocating rod 26. The reciprocating rod 26 is horizontally arranged, and a first connecting rod 27 is provided at the lower middle section of the reciprocating rod 26. The first connecting rod 27 and the reciprocating rod 26 form a T-shaped structure. A first stop rod 28 abuts against one side of the first connecting rod 27. The first stop rod 28 is provided on one side of the surface of the second rotating plate 25, and a second stop rod 29 is provided on the other side of the surface of the second rotating plate 25. The first stop rod 28 is used to intermittently push the first connecting rod 27 to move. The second stop lever 29 is used to intermittently push the L-rod 30 to swing. One end of the L-rod 30 is located on the side of the second rotating plate 25 near the second stop lever 29, and the other end of the L-rod 30 is located near the reciprocating rod 26. The corner of the L-rod 30 is rotatably mounted on the inner wall of the laminating machine. A U-shaped rod 31 is provided at the end of the L-rod 30 near the reciprocating rod 26. The bottom end of the U-shaped rod 31 is connected to one end of the L-rod 30. A driving block 32 is provided in the opening of the U-shaped rod 31. The driving block 32 is located on the surface of the reciprocating rod 26.

[0093] One end of the reciprocating rod 26 is used to drive the dust removal device, and the other end is used to drive the cutting device.

[0094] In the above embodiment, when the second rotating plate 25 is driven and rotated by the first gripper 21 and the second gripper 22, the second rotating plate 25 drives the first stop rod 28 and the second stop rod 29 to rotate around the center of the second rotating plate 25. When the first stop rod 28 or the second stop rod 29 moves to one side of the first connecting rod 27, the second rotating plate 25 drives the first stop rod 28 or the second stop rod 29 to continue rotating, thereby pushing the first connecting rod 27 to move. When the first connecting rod 27 moves, the horizontally sliding reciprocating rod 26 drives the dust removal device to work. Conversely, the second rotating plate 25 continues to rotate, thus... When the first stop 28 or the second stop 29 of the first connecting rod 27 disengages from the first connecting rod 27, the other first connecting rod 27 or the second connecting rod 39 abuts against one end of the L rod 30, thereby pushing the L rod 30 to rotate around its corner, causing the top of the L rod 30 to swing. This causes the U-shaped rod 31 on the L rod 30 to act on the drive block 32, causing the drive block 32 to move away from the dust removal device. This causes the reciprocating rod 26 to reset, and at the same time, the other end of the reciprocating rod 26 drives the cutting device to work, automatically cutting the film material. Example 14

[0095] Please see Figure 1-9 The cutting device is located at the end of the reciprocating rod 26 away from the dust removal device. A pull rope 33 is provided at the end of the reciprocating rod 26 away from the dust removal device. The pull rope 33 is connected to the cutting device through the steering wheel 34.

[0096] The cutting device includes a horizontal bar 35, one end of which is connected to the pull rope 33, and the projection plane of the horizontal bar 35 is perpendicular to the projection plane of the reciprocating rod 26.

[0097] The horizontal rod 35 slides horizontally at one end away from the pull rope 33. A first cutter 36 is provided on the surface of the end of the horizontal rod 35 away from the pull rope 33. A second cutter 37 is rotatably connected to the end of the first cutter 36 away from the horizontal rod 35. The shaft of a gear 38 is fixedly connected to the end of the second cutter 37 away from the first cutter 36. A second connecting rod 39 is rotatably provided on the side of the gear 38 away from the first cutter 36. A support frame 40 is rotatably connected to the end of the second connecting rod 39 away from the gear 38. The support frame 40 is located at the center of the gear ring 41. The teeth of the gear ring 41 face inward. The inner wall of the gear ring 41 is used to mesh with the gear 38.

[0098] In the above embodiment, when the reciprocating rod 26 moves back and forth, the horizontal rod 35 is pulled back and forth by the pull rope 33. The steering wheel 34 is used to change the direction of the pull force of the pull rope 33. When the horizontal rod 35 moves back and forth in the horizontal direction, the first cutter 36 pulls the second cutter 37 to make a circular motion around the first cutter 36. Since the second cutter 37 is fixedly connected to the gear 38, when the second cutter 37 rotates around the first cutter 36, the second cutter 37 pulls the gear 38 to move around the inner wall of the gear ring 41. When the second cutter 37 is above the first cutter 36, and the end of the second cutter 37 away from the first cutter 36 swings towards the first cutter 36, the first cutter 36 and the second cutter 37 close together, thereby realizing the cutting of the film material that has passed through the first cutter 36 and the second cutter 37. Example 15

[0099] Please see Figure 1-9 The dust removal device includes a cylinder, a rubber stopper is slidably disposed inside the cylinder, the rubber stopper is connected to the reciprocating rod 26, and a first nozzle 43 and a second nozzle 44 are connected to the cylinder tube. The first nozzle 43 and the second nozzle 44 are respectively disposed on one side of the cutting device and the second rotating plate 25.

[0100] The first nozzle 43 is located below one side of the first cutter 36.

[0101] In the above embodiment, the cylinder is connected to a one-way air intake valve, which is used to draw in air when the piston inside the cylinder reciprocates and to close the cylinder when compressing the cylinder, so that the cylinder can continuously supply air to the first nozzle 43 and the second nozzle 44.

[0102] When the first cutter 36 works with the second cutter 37 to cut the film material, the first nozzle 43 blows air from below the cut area of ​​the film material upwards, so that the cut area is suspended in the air. This allows the film material to be cut while suspended in the air when the first cutter 36 and the second cutter 37 cut the film material, avoiding the film material from folding during cutting, causing unevenness at the cut area, scratching the circuit surface of the PCB board, and generating air bubbles during pasting, which would affect the quality of the pasting.

[0103] When the first gripper 21 and the second gripper 22 rotate the product to be coated, the second nozzle 44 sprays air as the coating surface moves from bottom to top to clean the dust from the coating surface, thereby preventing dust and impurities from scratching the surface of the product to be coated.

[0104] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
