Description

Technical Field

[0001] The present invention relates to the field of chip technology, in particular to a protective film removal device for an optical sensor of a vehicle-mounted camera. Background Art

[0002] With the development of the automobile industry, especially the new energy automobile industry in recent years, the intelligence of automobiles has gradually attracted the attention of automobile manufacturers. At present, the rearview mirrors and side mirrors of many new energy vehicles use intelligent on-board cameras to replace ordinary reflectors.

[0003] Chip is a general term for semiconductor component products. It is a microcircuit that is miniaturized and manufactured on the surface of a semiconductor wafer. Chips are the brains of electronic devices and can perform various tasks, such as processing information, storing data, performing calculations and control operations. In order to protect the chip, the chip needs to be coated on its surface during production. After the chip is assembled with the PCB board, the protective film on its surface needs to be torn off.

[0004] The existing Chinese patent CN216902874U discloses a vacuum negative pressure separation mechanism for chip adhesive film, in which a blue film with an IC chip bonded thereto is placed on a film carrier and bonded thereto with tape. Since the top surface of the suction nozzle is flush with the top surface of the film carrier, the blue film contacts the suction nozzle, and then the air box is evacuated to a negative pressure, and the suction nozzle sucks the blue film downward and contacts the film tearing plate. The blue film bulges downward under the action of the scraper portion in the film tearing plate and the negative pressure, so when the synchronous belt transmission mechanism drives the negative pressure film tearing mechanism to move along the slide groove, the blue film is directly separated from the chip thereon. However, during the use of the above device, after the blue film is separated from the chip by negative pressure, although it is blocked by the scraper portion and the reinforcement portion and cannot enter the interior of the suction nozzle, the blue film after being separated from the chip will cover the upper side of the suction nozzle under the action of negative pressure, affecting the air intake flow of the air nozzle, affecting the subsequent film tearing work of the suction nozzle, and thus affecting the continuity of the film tearing work for batch chips.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention installs a film sticking mechanism and a film tearing mechanism. The pressing block in the film sticking mechanism moves down to push the tape to stick to the chip protective film. The film tearing wheel in the film tearing mechanism moves up to lift one side of the tape, so that the chip protective film can be torn off through the tape, which has a good film tearing effect on the chip. In addition, the driving wheel and the pressure wheel are used to transport the tape, which is conducive to tearing the film of multiple chips through the tape, so that the device has good continuity in tearing the film of batch chips and high film tearing efficiency.

[0019] 2. The present invention installs a pulling mechanism, in which a resist block resists an auxiliary wheel 1 located on the left side, and a pressing block 2 moves downward to drive the pulling wheel to move downward, so that the tape on the film reel can be pulled apart for a distance to prevent the tape from being unable to be pulled apart by the driving wheel alone, and the counterweight wheel can assist the pulling wheel in tensioning the tape, so as to facilitate the control of the moving length of the tape each time.

[0020] 3. The present invention installs a driving component, and when the pulling wheel moves downward to pull the tape, the pulling wheel contacts the flexible pad through a plurality of convex teeth, so that the pulling wheel can rotate clockwise during the downward movement, thereby facilitating the pulling force generated during the downward movement of the pulling wheel to act only on the tape on its right side, and effectively preventing the tape on the left side of the pulling wheel from being deformed or broken due to the tension.

[0021] 4. The present invention installs an adjustment component. The push block in the adjustment component can push the flexible pad to fit the convex teeth through the push rod during the downward movement. When the push block moves upward, the flexible pad will move away from the convex teeth driven by the compression force of the spring, which can effectively prevent the flexible pad from increasing the upward resistance of the push wheel. In addition, since a large gap is left between the flexible pad and the convex teeth after separation, it is convenient for disassembly and assembly of the tape.

[0022] 5. The present invention installs a material receiving component. When the driving wheel drives the adhesive tape of the mucosa to move, the lifting wheel will stretch the adhesive tape between the two auxiliary wheels under the action of its own gravity and the sliding seat 2, so that the adhesive tape is cached between the two auxiliary wheels. After the lower sensor detects the position of the sliding seat 2, the motor will reel up the adhesive tape cached between the two auxiliary wheels 2 through the reel one by one, which can effectively reduce the energy consumption of the motor 1.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figure 1 , Figure 2 , Figure 5 The protective film removal device for the optical sensor of a vehicle camera shown in the figure includes a frame 1 installed on the film tearing device, a film tearing station is arranged at the lower end of the frame 1, and also includes a film sticking mechanism for sticking the chip protective film, the film sticking mechanism is installed on the front side of the frame 1, the film sticking mechanism includes a film reel 2, and a tape for sticking the chip protective film is wound on the film reel 2; the film tearing mechanism is used to assist the film sticking mechanism to tear off the chip protective film, and the film tearing mechanism is installed at the film tearing station on the frame 1; the material pulling mechanism is used to pull open the tape wound on the film reel 2, and the material pulling mechanism is installed between the film reel 2 and the film tearing mechanism; the driving component is used to control the pulling direction of the material pulling mechanism, and the driving component is installed on the outside of the material pulling mechanism.

[0034] The adhesive film mechanism also includes a winding disk 3 rotatably mounted on the frame 1, and the winding disk 3 is located on the left side of the film disk 2, and the winding disk 3 is used to wind up the waste tape, and a motor 4 is fixedly mounted on the rear side of the frame 1 corresponding to the winding disk 3, and a cylinder 2 10 is fixedly mounted at the film tearing station of the frame 1, and a pressing block 9 is fixedly mounted on the driving end of the cylinder 2 10, and a pressure plate 7 is installed on the lower side of the pressing block 9, and the upper end of the pressure plate 7 is located on the rear side of the frame 1 and a cylinder 8 is fixedly mounted, and the cylinder 8 is fixedly connected to the frame 1, and a driving wheel 5 is also rotatably mounted on the frame 1, and the driving wheel 5 is located between the winding disk 3 and the cylinder 2 10, and a motor 2 18 is fixedly mounted on the rear side of the frame 1 corresponding to the driving wheel 5, and a pressure wheel 6 is movably abutted on the upper side of the driving wheel 5, and the connection between the pressure wheel 6 and the frame 1 is a rotating connection, and a plurality of guide wheels 48 for conducting the tape are also rotatably mounted on the frame 1.

[0035] The film tearing mechanism includes a film tearing wheel 11 and a film tearing wheel 12 installed on the left and right sides of the pressing block 19, and the film tearing wheel 11 and the film tearing wheel 12 are both located on the lower side of the tape. The front side of the frame 1 is provided with two symmetrically distributed connecting seats 13 that are movably fitted corresponding to the film tearing wheel 11 and the film tearing wheel 12, and the film tearing wheel 11 and the film tearing wheel 12 are both rotatably connected to the connecting seats 13, and a cylinder 3 14 is fixedly installed on the upper end of the connecting seat 13, and the connection between the cylinder 3 14 and the frame 1 is a fixed connection.

[0036] Working principle: the chip covered with the protective film is mounted on the PCB board, and the feeding mechanism in the film tearing equipment conveys the batch of PCB boards. After conveying the chip and the PCB board to the film tearing station of the frame 1, the cylinder 1 8 drives the pressure plate 7 to move down and press the PCB board, and then the cylinder 2 10 drives the pressing block 1 9 to move down, driving the tape to move down and stick to the protective film of the chip. In this process, the film tearing wheel 1 1 and the film tearing wheel 2 12 move down synchronously, and the cylinder 2 10 drives the pressing block 1 9 to move up and reset. The cylinder 3 14 of the film tearing wheel 1 1 drives it to move up and reset first. Since the film tearing wheel 1 1 and the film tearing wheel 2 12 are both located on the lower side of the tape, when the film tearing wheel 1 1 moves up and resets first, the left side of the tape can be lifted first, and then the film tearing wheel 2 12 moves up and resets, so that the tape can tear the chip protective film, which is conducive to the complete removal of the chip protective film, and the film tearing effect is good.

[0037] After the film is peeled off for a chip, the motor 2 18 drives the driving wheel 5 to rotate a certain angle. Since the pressure wheel 6 is in contact with the driving wheel 5, the tape is squeezed (the distance between the pressure wheel 6 and the driving wheel 5 can be changed, which belongs to the prior art and will not be elaborated here. The distance between the pressure wheel 6 and the driving wheel 5 is enlarged to facilitate the installation of the tape). Therefore, when the driving wheel 5 rotates, the tape with the protective film can be transported for a certain distance, which is conducive to peeling off the film of multiple chips through the tape, so that the device has good continuity and high efficiency in peeling off the film of batch chips.

[0038] Example 2: Please refer to Figure 3 This embodiment further explains Example 1. The pulling mechanism includes a cylinder 4 15 fixedly installed on the front side of the frame 1. A pressing block 2 16 is fixedly installed on the driving end of the cylinder 4 15. Two auxiliary wheels 17 that are symmetrically distributed are rotatably installed on the outer sides of the pressing block 2 16 on the frame 1. A slide rail 19 is installed between the two auxiliary wheels 17, and the connection between the slide rail 19 and the frame 1 is a fixed connection. A slide seat 20 is slidably installed on the slide rail 19, and a pulling wheel 21 is rotatably installed on the front side of the slide seat 20, and the pulling wheel 21 can move up and down.

[0039] A baffle 22 is installed on the upper side of the pulling wheel 21, and the connection between the baffle 22 and the slide 20 is a fixed connection, the connection between the pressing block 216 and the baffle 22 is a movable abutment, and a counterweight wheel 23 is also installed on the front side of the slide 20, and the counterweight wheel 23 is located on the lower side of the pulling wheel 21, and a stop block 24 is installed on the outer side of an auxiliary wheel 17 located on the left side, and the stop block 24 abuts against the auxiliary wheel 17 located on the left side to prevent it from rotating, and a cylinder 5 25 is fixedly connected to the side of the stop block 24 away from the auxiliary wheel 17, and the connection between the cylinder 5 25 and the frame 1 is a fixed connection.

[0040] In this embodiment: during the process of adhesive tape filming, the pulling wheel 21 tensions the tape through the gravity of the counterweight wheel 23, and each time the driving wheel 5 rotates to convey a section of the tape, the pulling wheel 21 moves up one unit;

[0041] When the pulling wheel 21 moves up to the highest point, the cylinder five 25 drives the stop block 24 to press against an auxiliary wheel 17 on the left side, and the blocking tape drives the auxiliary wheel 17 on the left side to rotate. Then the cylinder four 15 drives the pressing block 2 16 to move down, and the pressing block 2 16 pushes the pulling wheel 21 to move down through the baffle 22. The downward movement of the pulling wheel 21 makes the length between the two auxiliary wheels 17 longer, and this reciprocating motion prevents the driving wheel from being unable to pull the tape away from the film reel 2 due to the stickiness of the tape.

[0042] Example 3: Please refer to Figure 3 , Figure 6The present embodiment further explains the first embodiment, the driving assembly includes two symmetrically distributed fixing bars 28 installed on the left side of the pulling wheel 21, a flexible pad 29 is fixedly embedded on the side of the fixing bar 28 close to the pulling wheel 21, an anti-slip sleeve 26 is fixedly sleeved on the outer side of the pulling wheel 21 corresponding to the area in contact with the tape, a plurality of convex teeth 27 equidistantly distributed on the circumference are provided on the outer side of the pulling wheel 21 corresponding to the flexible pad 29, and the pulling wheel 21 is in rolling contact with the flexible pad 29 through the convex teeth 27, the convex teeth 27 are used to increase the friction resistance between the pulling wheel 21 and the flexible pad 29, and a plurality of fixing rods 30 equidistantly distributed are fixedly installed between the two fixing bars 28.

[0043] The fixing rod 30 is in sliding contact with the frame 1 through a limiting straight groove 1, and two symmetrically distributed positioning bars 31 are fixedly sleeved on the outer side of the fixing rod 30, and the two positioning bars 31 are respectively located on the front and rear sides of the frame 1, and a plurality of springs 1 32 distributed at equal distances are fixedly installed on the right side of a positioning bar 31 located on the rear side of the frame 1, and the plurality of springs 1 32 are used to drive the flexible pad 29 away from the convex tooth 27, and one end of the spring 1 32 away from the positioning bar 31 is fixedly connected to a blocking bar 33, and the connection between the blocking bar 33 and the frame 1 is a fixed connection.

[0044] In this embodiment: since the multiple protruding teeth 27 on the outside of the pulling wheel 21 will abut against the flexible pad 29, during the downward movement of the pulling wheel 21, the flexible pad 29 drives the pulling wheel 21 to rotate clockwise through the multiple protruding teeth 27, which is beneficial for the pulling force generated during the downward movement of the pulling wheel 21 to act only on the tape on its right side. Therefore, after the stop block 24 positions the auxiliary wheel 17 on the left side, the clockwise rotation of the pulling wheel 21 can effectively prevent the tape on the left side of the pulling wheel from being deformed or broken due to the tension.

[0045] Example 4: Please refer to Figure 7 , Figure 8 The present embodiment further explains the first embodiment, that an adjustment assembly is installed between the driving assembly and the piston rod of the cylinder four 15, and the adjustment assembly includes a connecting strip 34 movably sleeved on the outer side of the piston rod of the cylinder four 15, and the connection between the connecting strip 34 and the pressing block two 16 is a movable abutment, and the connecting strip 34 is in sliding contact with the frame 1 through the limiting straight groove two, and the rear end of the connecting strip 34 is fixedly connected with a bending strip 35, and the bending strip 35 is movably fitted with the rear side wall of the frame 1, and a plurality of push blocks 36 distributed at equal distances are fixedly installed on the side of the bending strip 35 close to the positioning strip 31, and the push block 36 is respectively provided with a vertical portion and a bevel portion on the side close to the positioning strip 31, and the vertical portion is located on the upper side of the bevel portion.

[0046] A push rod 37 having the same number as the push block 36 is fixedly installed on one side of the positioning bar 31 close to the push block 36, and a ball 38 is movably embedded in one end of the push rod 37 close to the push block 36, and the ball 38 is in rolling contact with the vertical portion and the bevel portion of the push block 36. When the ball 38 abuts against the vertical portion of the push block 36, the flexible pad 29 will abut against the convex tooth 27 and cannot move. A pin rod 39 is fixedly embedded in the upper end of the bending bar 35, and a stopper 40 is movably sleeved on the outer side of the pin rod 39, and the connection between the stopper 40 and the frame 1 is a fixed connection. A spring 2 41 is also movably sleeved on the outer side of the pin rod 39, and the two ends of the spring 2 41 are respectively movably abutted against the bending bar 35 and the stopper 40, and a guide rail 42 is movably embedded in the side of the bending bar 35 close to the frame 1, and the connection between the guide rail 42 and the frame 1 is a fixed connection.

[0047] In this embodiment: before the pressing block 16 moves downward but does not contact the baffle 22, the bending strip 35 will move downward under the drive of the spring 2 41, and the plurality of push blocks 36 can drive the push rod 37 and the flexible pad 29 to move to the right through the ball 38 during the downward movement of the bending strip 35, so that the flexible pad 29 fits with the plurality of convex teeth 27, and at this time, the ball 38 abuts against the vertical part of the push block 36, so that during the downward movement of the pulling wheel 21, the flexible pad 29 can drive the pulling wheel 21 to move along the right through the plurality of convex teeth 27. As the clockwise direction rotates, during the process of the cylinder four 15 driving the pressing block two 16 to move up and reset, the pressing block two 16 will drive the connecting strip 34 and the bending strip 35 to move up. After the bending strip 35 drives the multiple pushing blocks 36 to move up, the positioning strip 31 and the flexible pad 29 will be driven away from the convex tooth 27 by the compression elastic force of the multiple springs one 32, which can effectively prevent the flexible pad 29 from increasing the upward resistance of the pushing wheel 21. In addition, since a large gap is left between the flexible pad 29 and the convex tooth 27 after separation, it is convenient for the disassembly and assembly of the tape.

[0048] Example 5: Please refer to Figure 1 , Figure 4 , this embodiment further explains the second embodiment, a material receiving assembly is further installed between the front side of the frame 1 corresponding to the winding disk 3 and the pressure wheel 6, and the material receiving assembly includes a slide rail 2 43 fixedly installed on the front side of the frame 1, a slide seat 2 44 is slidably installed on the slide rail 2 43, a lifting wheel 45 is rotatably installed on the front side of the slide seat 2 44, two symmetrically distributed auxiliary wheels 2 46 are installed on the upper side of the slide rail 2 43, and the connection between the auxiliary wheels 2 46 and the frame 1 is a rotating connection, two symmetrically distributed sensors 47 are installed on the left side of the slide rail 2 43 and the slide seat 2 44, and the connection between the sensor 47 and the frame 1 is a fixed connection, and the sensor 47 is used to detect the position of the lifting wheel 45.

[0049] In this embodiment: when the driving wheel 5 drives the tape of the mucosa to move, the lifting wheel 45 will stretch the tape between the two auxiliary wheels 46 under the action of its own gravity and the slide 44, so that the tape is cached between the two auxiliary wheels 46. When the lower sensor 47 detects the position of the slide 44, the motor 4 will once again reel up the tape cached between the two auxiliary wheels 46 through the reel 3, which can effectively reduce the energy consumption of the motor 4. When the lifting wheel 45 moves up to the upper sensor 47, the motor 4 stops running.
