Description

[0001] The invention relates to the technical field of circuit board production equipment, and in particular to a material protective film removal mechanism and a method thereof. Background Art

[0002] In order to protect certain features on the material, such as solder joints and glue points on flexible circuit boards, a protective film is usually attached to the material to protect the features and prevent damage to the features during transportation. When the material is used, the protective film attached to the material needs to be removed first, and the protective film is attached to the material, making it difficult to separate the protective film from the material.

[0003] In the prior art, the gripper without glue on the protective film is usually grasped by the clamp to tear it off. Since the free state of the gripper of the protective film cannot be controlled, this protective film removal method cannot achieve the effect of accurately tearing off the protective film. This protective film removal method cannot tear off the protective film without a gripper, and cannot meet the user's high-precision and high-efficiency film removal requirements for large quantities of materials.

[0007] In one of the embodiments, the elastic component of the material protection film removal mechanism includes two symmetrically arranged second springs, one end of the second spring is connected to the clamping plate, and the other end of the second spring is connected to the fixing block.

[0008] In one embodiment, the rotary unwinding assembly of the material protective film removal mechanism includes a motor, a first rotating wheel, a second rotating wheel and a transmission belt assembly. The first rotating wheel and the second rotating wheel are respectively located on both sides of the film tearing assembly and are lower than the film tearing assembly. The driving end of the motor passes through the working frame and is connected to the first rotating wheel and one end of the transmission belt assembly. One end of the second rotating wheel is rotatably connected to the working frame, and the other end of the second rotating wheel is connected to the other end of the transmission belt assembly. The motor is used to drive the first rotating wheel and the transmission belt assembly to rotate. The first rotating wheel drives the film tearing tape to rotate, and the transmission belt assembly drives the second rotating wheel and the film tearing tape to rotate.

[0015] A material protective film removal method, using a material protective film removal mechanism, the specific steps are as follows:

[0016] Step 1: Place the tearing tape reel on the unloading turntable of the unloading assembly. The tearing tape passes through the third rotating wheel, the first rotating wheel, the positioning groove of the support block and the second rotating wheel in sequence, and is finally wound on the recovery turntable.

[0018] Step 3: After the film tearing of a material is completed, the motor of the rotating unwinding assembly drives the first rotating wheel and the transmission belt assembly to rotate, the first rotating wheel drives the film tearing tape to rotate a distance of a material, and the transmission belt assembly drives the film tearing tape on the second rotating wheel to rotate a distance of a material synchronously. While the first rotating wheel drives the film tearing tape to rotate, the film tearing tape disk drives the unloading turntable of the unloading assembly to rotate, and the damper is set with a damping value, so that the film tearing tape is in a tensioned state;

[0019] Step 4: After the first rotating wheel rotates, the torque motor of the recycling component drives the recycling turntable to rotate, and the recycling turntable drives the tearing tape to rotate and recycle after the film is torn, so that the tearing tape is in a tensioned state.

[0020] The beneficial effects of this application are:

[0021] The present application provides a material protective film removal mechanism, which realizes the unwinding and recycling of the film-tearing tape through the cooperation between the unwinding component, the rotating unwinding component, the pressing component, the film-tearing component and the recycling component, and also realizes the high-precision film removal operation of multiple materials. The material protective film removal mechanism not only realizes high-precision film removal, but also improves the film removal efficiency.

[0022] The material protective film removal mechanism uses a suction component, a clamping plate component and a support block to cooperate with each other to tear off the protective film on the material, so as to achieve the tearing off of the protective film with or without a gripper on the material, and the tearing effect is very good, and the tearing success rate can reach 100%. The film can also be torn off the surface of the material with a curved structure by changing the style of the suction head, clamping plate and support block.

[0023] The material protective film removal mechanism adopts a rotary unwinding component to unwind the tearing tape a material distance, thereby realizing control over the unwinding length of the tearing tape, which not only saves the cost of the tearing tape but also improves the unwinding efficiency.

[0024] The material protective film removal mechanism uses a clamping component to clamp the film-tearing tape on the first rotating wheel, which can prevent the first rotating wheel from idling without driving the tape and avoid the next material film removal failure. The position relationship between the clamping component and the first rotating wheel can also be adjusted according to the clamping requirements.

[0025] The material protective film removal mechanism adopts a discharging component and a recycling component to discharge and recycle the film tearing tape. During the discharging and recycling process, the film tearing tape is ensured to be always in a tensioned state, which can avoid the occurrence of looseness of the film tearing tape, thereby improving the film tearing accuracy and efficiency of the film tearing tape.

[0038] Specifically, the clamping assembly 4, the rotary unwinding assembly 3 and the film tearing assembly 2 are respectively mounted on the upper end surface of the working frame, the clamping assembly 4 and the film tearing assembly 2 are respectively located on both sides of the rotary unwinding assembly 3, the unloading assembly 6 and the recycling assembly 5 are respectively mounted on the lower end surface of the working frame, the unloading assembly 6 is located below the clamping assembly 4, and the recycling assembly 5 is located below the film tearing assembly 2 and the rotary unwinding assembly 3. The clamping assembly 4 and the working frame are slidably matched with the slider and the slide rail to adjust the position of the clamping assembly 4. After the position is adjusted, the sliding seat 403 of the clamping assembly 4 can be fixedly connected to the working frame by the bolt assembly, so that the clamping wheel 404 of the clamping assembly 4 is pressed on the first rotating wheel 302 of the rotary unwinding assembly 3. Among them, the lifting drive mechanism of the film tearing assembly 2 is mounted on the side end of the working frame, and the driving end of the lifting drive mechanism is connected to the suction head 201. The side end of the support block 203 is connected to the working frame, the positioning groove 202 of the support block 203 not only positions the film-tearing tape 8, but also adapts to the material 1, the side end of the fixed plate is connected to the working frame, the clamping plate 204 is connected to the fixed plate through the elastic component 205, and the clamping plate 204 is spaced a certain distance from the working frame, so that the clamping plate 204 does not contact the film-tearing tape 8 during the up and down movement. The upper surface of the clamping plate 204 is higher than the upper surface of the support block 203. The clamping plate 204 is located at the side end of the support block 203 and is close to the first rotating wheel 302 of the rotating unwinding component 3. Among them, the material 1 includes a material body 101 and a protective film 102, and the protective film 102 is attached to the material body 101.

[0039] The film-tearing tape reel is placed on the discharge turntable 602 of the discharge assembly 6, and the film-tearing tape 8 passes through the third rotating wheel 9, the first rotating wheel 302, the positioning groove 202 of the support block 203 and the second rotating wheel 303 in sequence, and is finally wound on the recovery turntable 502, and the pressing wheel 404 of the pressing assembly 4 presses the film-tearing tape 8 on the first rotating wheel 302; the lifting drive mechanism of the film-tearing assembly 2 drives the suction head 201 to suck the material 1, and the lifting drive mechanism drives the suction head 2 01 and material 1 move toward the support block 203, the end of the material 1 without the protective film 102 first contacts the clamping plate 204 of the clamping plate assembly, and then continues to press down, when the upper surface of the clamping plate 204 is flush with the upper surface of the positioning groove 202 of the support block 203, the end of the material 1 with the protective film 102 is tightly attached to the film tearing tape 8 of the support block 203, and then the lifting drive mechanism drives the suction head 201 and the material 1 to move upward, and the clamping plate 204 of the clamping plate assembly is elastically pressed. Under the action of the force of component 205, the clamped material 1 moves upward, so that the protective film 102 of the material 1 is separated from the material body 101 and adhered to the film-tearing tape 8; after the film tearing of one material 1 is completed, the motor 301 of the rotating unwinding component 3 drives the first rotating wheel 302 and the transmission belt component 304 to rotate, the first rotating wheel 302 drives the film-tearing tape 8 to rotate a distance of one material 1, and the conveyor belt component drives the film-tearing tape 8 on the second rotating wheel 303 to synchronously rotate a distance of one material 1, and while the first rotating wheel 302 drives the film-tearing tape 8 to rotate, the film-tearing tape disk drives the material discharge turntable 602 of the material discharge component 6 to rotate, and the damper 601 is set with a damping value, so that the film-tearing tape 8 is in a tensioned state; when the first rotating wheel 302 rotates, the torque motor 501 of the recovery component 5 drives the recovery turntable 502 to rotate, and the recovery turntable 502 drives the film-tearing tape 8 after the film is torn to rotate and recover, so that the film-tearing tape 8 is in a tensioned state. Then continue with a new round of material 1 demembrane operation.

[0040] In the above structure, the protective film 102 on the material 1 is torn off by the cooperation of the suction component, the clamping plate component and the support block 203, so as to realize the tearing off of the material 1 with or without the gripper protective film 102, and the tearing off effect is very good, and the tearing off success rate can reach 100%. The surface of the material 1 with a curved structure can also be subjected to film tearing treatment by changing the style of the suction head 201, the clamping plate 204 and the support block 203. The unwinding and recycling of the film tearing tape 8 are also realized by the cooperation between the unwinding component 6, the rotating unwinding component 3, the pressing component 4, the film tearing component 2 and the recycling component 5, and the high-precision film removal operation of multiple materials 1 is also realized. The material protective film removal mechanism not only realizes high-precision film removal, but also improves the film removal efficiency.

[0041] like Figure 3As shown, in one embodiment, the elastic component 205 of the material protective film removal mechanism includes two symmetrically arranged second springs, one end of the second spring is connected to the clamping plate 204, and the other end of the second spring is connected to the fixed block 206. When the lifting drive mechanism drives the suction head 201 and the material 1 to press down, when the clamping plate 204 is subjected to force, the two second springs are forced to compress toward the fixed block 206; when the lifting drive mechanism drives the suction head 201 and the material 1 to move upward, when the clamping plate 204 is not subjected to force, the clamping plate 204 clamps the material 1 and moves it upward to reset under the action of the two second spring forces. The arrangement of the clamping plate 204 and the second spring can prevent the material 1 from being attached to the tearing tape 8 and detaching from the suction head 201 when the material 1 is pressed down on the tearing tape 8.

[0042] like Figure 4 As shown, in one embodiment, the rotating unwinding assembly 3 of the material protective film removal mechanism includes a motor 301, a first rotating wheel 302, a second rotating wheel 303 and a transmission belt assembly 304, the first rotating wheel 302 and the second rotating wheel 303 are respectively located on both sides of the film tearing assembly 2 and are lower than the film tearing assembly 2, the driving end of the motor 301 passes through the working frame and is connected to the first rotating wheel 302 and one end of the transmission belt assembly 304, one end of the second rotating wheel 303 is rotatably connected to the working frame, and the other end of the second rotating wheel 303 is connected to the other end of the transmission belt assembly 304, the motor 301 is used to drive the first rotating wheel 302 and the transmission belt assembly 304 to rotate, the first rotating wheel 302 drives the film tearing tape 8 to rotate, and the transmission belt assembly 304 drives the second rotating wheel 303 and the film tearing tape 8 to rotate. The motor 301 drives the first rotating wheel 302 and one end of the transmission belt assembly 304 to rotate the distance of one material 1 at the same time, and the first rotating wheel 302 drives the film-tearing tape 8 to rotate the distance of one material 1, and the transmission belt assembly 304 drives the second rotating wheel 303 and the film-tearing tape 8 on the second rotating wheel 303 to rotate the distance of one material 1. The first rotating wheel 302 and the second rotating wheel 303 are rubber-coated wheels that facilitate driving the film-tearing tape 8 to rotate. This setting can ensure that the film-tearing tape 8 rotates synchronously, prevent the film-tearing tape 8 from becoming loose, and effectively control the rotation distance of the film-tearing tape 8, save the use cost of the film-tearing tape 8, and improve the unwinding efficiency.

[0043] like Figure 4 As shown, in one embodiment, the drive belt assembly 304 of the material protective film removal mechanism includes a driving wheel, a driven wheel, and a belt line wound around the driving wheel and the driven wheel, the driving wheel is connected to the first rotating wheel 302, and the driven wheel is connected to the second rotating wheel 303. When the motor 301 drives the first rotating wheel 302 to rotate, the first rotating wheel 302 rotates to drive the driving wheel to rotate, the driving wheel drives the belt line and the driven wheel to rotate, and the driven wheel drives the second rotating wheel 303 to rotate. This arrangement facilitates driving the second rotating wheel 303 to drive the film tearing tape 8 to rotate at the same time.

[0044] like Figure 5 As shown, in one embodiment, the clamping assembly 4 of the material protective film removal mechanism includes a sliding seat 403, a fixed seat 401, a clamping wheel 404 and two first springs 402. The two ends of the sliding seat 403 are adjustably connected to the working frame, the sliding seat 403 and the fixed seat 401 are connected by two first springs 402, and the clamping wheel 404 is rotatably connected to the end of the fixed seat 401 away from the sliding seat 403. The sliding seat 403 and the fixed seat 401 are respectively matched with the working frame through a slider and a slide rail for horizontal sliding. The sliding seat 403 is manually pushed to drive the fixed seat 401 and the clamping wheel 404 to move, so as to adjust the clamping position of the clamping wheel 404 on the film-tearing tape 8 on the first rotating wheel 302. After adjustment, the sliding seat 403 and the working frame are fixed by a bolt assembly. The two first springs 402 arranged between the sliding seat 403 and the fixed seat 401 can provide a certain pressure to the fixed seat 401 under stress, thereby realizing the clamping force on the film-tearing tape 8 on the first rotating wheel 302. This setting can not only adjust the pressing position, but also prevent the first rotating wheel 302 from idling, thereby ensuring that the film-tearing tape 8 rotates with the first rotating wheel 302 and ensuring normal film removal of the material 1.

[0045] like Figure 7 As shown, in one embodiment, the material discharging assembly 6 of the material protective film removal mechanism includes a damper 601 and a discharging turntable 602 for placing the film tearing tape disk, and the damper 601 is installed on the work frame, and the damper 601 is connected to the discharging turntable 602. When the motor 301 drives the first rotating wheel 302 to drive the film tearing tape 8 to rotate, the rotation of the film tearing tape 8 drives the discharging turntable 602 to rotate. Since the damper 601 is set with a damping value, the rotation of the discharging turntable 602 can be controlled to ensure that the film tearing tape 8 is in a tensioned state, to prevent the film tearing tape 8 from becoming loose, and to ensure the film tearing efficiency.

[0046] like Figure 6As shown, in one embodiment, the recycling component 5 of the material protective film removal mechanism includes a torque motor 501 and a recycling turntable 502 for recycling the film-tearing tape 8. The torque motor 501 is installed on the work frame, and the driving end of the torque motor 501 is connected to the recycling turntable 502. The torque motor 501 is used to drive the recycling turntable 502 to rotate. When the motor 301 drives the first rotating wheel 302 to drive the film-tearing tape 8 to rotate, the film-tearing tape 8 that has been torn is in a relaxed state, and the torque motor 501 drives the recycling turntable 502 to rotate, and the relaxed film-tearing tape 8 is wound on the recycling turntable 502 until the film-tearing tape 8 is in a tensioned state, and the torque motor 501 stops when it reaches the set torque value. This setting can not only recycle the film-tearing tape 8 after the film is torn, but also ensure that the film-tearing tape 8 is in a tensioned state, which can avoid the occurrence of loose film-tearing tape 8, thereby improving the film-tearing accuracy and efficiency of the film-tearing tape 8.

[0047] like Figure 1 As shown, in one embodiment, a third rotating wheel 9 for the film-tearing tape 8 to pass through is arranged between the rotating unwinding assembly 3 and the unwinding assembly 6 of the material protective film removal mechanism, and the third rotating wheel 9 is rotatably connected to the working frame. The third rotating wheel 9 is a rubber-coated wheel that is convenient for driving the film-tearing tape 8 to rotate. This arrangement supports the film-tearing tape 8 between the rotating unwinding assembly 3 and the unwinding assembly 6, and effectively improves the flatness of the film-tearing tape 8 during the rotation process.

[0048] like Figure 1 As shown, in one embodiment, a photoelectric sensor 7 for detecting the presence of a tearing tape 8 is provided on the working frame of the material protection film removal mechanism, and the photoelectric sensor 7 is located between the rotating unwinding component 3 and the material discharge component 6. The photoelectric sensor 7 is provided to facilitate the detection of the presence of the tearing tape 8 between the rotating unwinding component 3 and the material discharge component 6, and when the tearing tape 8 is used up, the staff can be reminded in time to load the tearing tape 8.

[0049] like Figure 1 As shown, the embodiment of the present application also provides a material protective film removal method, which uses a material protective film removal mechanism, and the specific steps are as follows:

[0050] Step 1: Place the tearing tape reel on the unloading turntable 602 of the unloading assembly 6, and the tearing tape 8 passes through the third rotating wheel 9, the first rotating wheel 302, the support block 203 and the second rotating wheel 303 in sequence, and finally winds on the recovery rotating wheel 502, and the pressing wheel 404 of the pressing assembly 4 presses the tearing tape 8 on the first rotating wheel 302;

[0051] Step 2: The lifting drive mechanism of the film tearing assembly 2 drives the suction head 201 to suck the material 1 tightly, and then the lifting drive mechanism drives the suction head 201 and the material 1 to move toward the support block 203. The end of the material 1 without the protective film 102 first contacts the clamping plate 204 of the clamping plate assembly, and then continues to press down. When the upper surface of the clamping plate 204 is flush with the upper surface of the support block 203, the end of the material 1 with the protective film 102 is tightly attached to the film tearing tape 8 of the support block 203. Then the lifting drive mechanism drives the suction head 201 and the material 1 to move upward. The clamping plate 204 of the clamping plate assembly moves upward simultaneously with the material 1 under the action of the elastic assembly 205, so that the protective film 102 of the material 1 is separated from the material body 101 and attached to the film tearing tape 8.

[0052] Step 3: After the film tearing of a material 1 is completed, the motor 301 of the rotating unwinding assembly 3 drives the first rotating wheel 302 and the transmission belt assembly 304 to rotate, the first rotating wheel 302 drives the film tearing tape 8 to rotate a distance of a material 1, and the transmission belt assembly drives the film tearing tape 8 on the second rotating wheel 303 to rotate a distance of a material 1 synchronously, while the first rotating wheel 302 drives the film tearing tape 8 to rotate, the film tearing tape disk drives the material discharge turntable 602 of the material discharge assembly 6 to rotate, and the damper 601 is set with a damping value, so that the film tearing tape 8 is in a tensioned state;

[0053] Step 4: After the first rotating wheel 302 rotates, the torque motor 501 of the recovery component 5 drives the recovery turntable 502 to rotate, and the recovery turntable 502 drives the film-tearing tape 8 to rotate and recover after the film is torn, so that the film-tearing tape 8 is in a tensioned state.

[0054] After the above steps are completed, the motor 301 drives the first rotating wheel 302 to drive the film-tearing tape 8 to rotate, and a new round of film-tearing operation of the material 1 is performed. This method not only improves the tensioning effect of the film-tearing tape, but also realizes the tearing of the material with or without the gripper protective film, and the tearing effect is very good, and the tearing success rate can reach 100%.

[0055] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
