Description

Technical Field

[0001] This invention belongs to the field of film-applied packaging technology, and specifically relates to an automatic film-applied packaging device. Background Technology

[0002] An automatic labeling machine is a device that affixes rolls of paper, protective film, or metal foil labels to specified packaging containers or products. The labels have adhesive backing and are arranged regularly on a glossy backing paper. The labeling machine's peeling mechanism automatically peels them off and attaches them to the product. It can perform various operations such as flat labeling, single-sided or multi-sided labeling of packaging, cylindrical labeling, partial or full coverage of cylindrical surfaces, and labeling of recessed and corner areas.

[0003] However, conventional automatic labeling machines only apply labels. When applying protective films to small objects such as electronic components, not only is labeling machine operation necessary, but several components also need to be screened and arranged before the protective film is applied. This screening and arrangement usually requires other equipment, followed by manual placement into the labeling machine's protective film application area for application. Furthermore, because electronic components are easily damaged, they typically need to be sealed onto a special carrier tape after the protective film is applied, requiring manual sealing. This not only wastes manpower but also leads to low efficiency. Moreover, multiple steps need to be processed on multiple machines, reducing processing efficiency. Therefore, there is a need to design a device that can simultaneously perform screening, arrangement, protective film application, and sealing. Based on this, an automatic film application and sealing device is proposed. Summary of the Invention

[0004] To address the problem that multiple steps in existing technologies require processing on multiple devices, this invention provides an automated film-applying and packaging device.

[0005] The objective of this invention can be achieved through the following technical solutions: An automatic film-applying and packaging device of the present invention includes a frame and a peeling assembly, a vibratory feeder assembly, a moving assembly, a conveying assembly, a photographing assembly, and a sealing assembly, all disposed within the frame and electrically connected to a control module. The conveying assembly is disposed on the moving assembly and includes a suction head, a sensor, and an air pump. The air pump is connected to the suction head. The conveying assembly uses the suction head to pick up the protective film on the peeling assembly and attach it to the part on the vibratory feeder assembly, and picks up and moves the part with the attached protective film to the carrier belt of the sealing assembly. The conveying assembly descends and drives the sealing assembly to seal the carrier belt containing the part and instructs the peeling assembly to peel off the film.

[0006] Furthermore, the conveying assembly includes a cylinder mounting plate, on which a variable pitch cylinder and the air pump are mounted. Several telescopic guide posts are connected to the variable pitch cylinder, and each telescopic guide post is connected to a suction head. The suction head is equipped with a spring and an annular telescopic wall. The spring is used to push the annular telescopic wall out of the bottom of the suction head. The area around the bottom of the suction head surrounded by the annular telescopic wall forms a negative pressure feeding port for sucking up the protective film and the parts with the protective film attached. The annular telescopic wall is used to limit the position of the protective film and the parts and reduce air leakage from the suction head. The retraction of the annular telescopic wall is used to push the protective film along its inner wall direction and attach it to the parts.

[0007] Furthermore, a first pressure sensor is provided at the bottom of the annular telescopic wall, and a second pressure sensor is provided at the bottom of the suction head. The telescopic guide column, the first pressure sensor, and the second pressure sensor are all electrically connected to the control module on the moving component. The control module is used to instruct the telescopic guide column to stop moving downward and start the air pump when the first pressure sensor is subjected to force for the first time, so that the suction head can pick up the protective film. When the first pressure sensor is subjected to force for the second time and both the first and second pressure sensors are subjected to force, the control module instructs the telescopic guide column to stop moving downward and stick the protective film and pick up the part. When the second pressure sensor is subjected to force alone, the control module instructs the telescopic guide column to stop moving downward and release the part. The control module operates in a cycle of three movements of the telescopic guide column.

[0008] Furthermore, the air pump is electrically connected to the control module. The control module is used to instruct the air pump to start a primary suction force to adsorb the protective film and release the parts when the first pressure sensor or the second pressure sensor is subjected to force alone, and to instruct the air pump to start a secondary suction force to adsorb the parts when both the first pressure sensor and the second pressure sensor are subjected to force.

[0009] Furthermore, the moving assembly also includes an X-axis motor, a Y-axis connecting plate, a Y-axis motor, a Y-axis track, and a Z-axis connecting plate. The X-axis motor is mounted on one of the X-axis gantry frames. The bottom sides of the Y-axis connecting plate are horizontally slidably connected to the X-axis track on the X-axis gantry frame. The Y-axis motor and the Y-axis track are mounted on the Y-axis connecting plate. The Z-axis connecting plate is vertically slidably mounted on the Y-axis track. The conveying assembly is mounted on the Z-axis connecting plate. The conveying assembly is used to pick up the protective film and parts. The X-axis motor is used to drive the Y-axis connecting plate to move horizontally. The Y-axis motor is used to drive the Z-axis connecting plate to move vertically. The cylinder mounting plate is connected to the side of the Z-axis connecting plate.

[0010] Furthermore, the vibratory feeder assembly includes two vibratory feeders, a vibratory track, and a straight vibrator. The two vibratory feeders are arranged opposite each other and their output ports are connected to the vibratory track. A straight vibrator is arranged below the vibratory track. The product receiving platform is located at the end of the vibratory track. A receiving plate is provided on the product receiving platform, and a receiving groove is formed on the receiving plate.

[0011] Furthermore, the sealing assembly includes a sealing platform, on which a guide rail is provided for placing the carrier tape. A limiting plate is provided on the guide rail, and a material discharge groove is provided on the limiting plate. The material discharge groove is used to separately abut against the second pressure sensor at the bottom of the suction head to receive force.

[0012] Furthermore, the sealing platform has a carrier tape feeding tray and a carrier tape receiving tray at both ends of the guide rail for releasing and retrieving the carrier tape bottom plate, respectively. A coating material placement mechanism is provided above the guide rail for releasing the carrier tape cover plate. A roller seat is provided on the sealing platform below the coating material placement mechanism. A roller is rotatably mounted on the roller seat. A ratchet is coaxially connected to the roller. An abutment rod that interferes with the cylinder mounting plate is arranged in a circular array on the outside of the ratchet. The cylinder mounting plate descends and pushes the abutment rod to drive the ratchet and roller to rotate. The roller rotates and the teeth apply pressure to the stacked carrier tape cover plate and carrier tape bottom plate to close them and push the carrier tape forward. A coating material hot pressing mechanism is provided on the sealing platform at the rear end of the roller for sealing the closed carrier tape cover plate and carrier tape bottom plate.

[0013] Furthermore, the camera component is electrically connected to the control module. The camera component is used to acquire the status of the protective film being sucked up by several suction heads. The control module is used to instruct the air pump to stop starting when the camera component acquires that several suction heads are missing the protective film, so as to release all the protective film.

[0014] Furthermore, the upper surface of the protective film receiving platform of the stripping assembly is serrated, and a through groove is provided at the material picking area of ​​the protective film receiving platform.

[0015] The beneficial effects of this invention are as follows: (1) First, the protective film on the slip paper needs to be peeled off by the peeling component and placed on the protective film receiving platform. At the same time, the part is transported to the product receiving platform by the vibrating plate component. Then, the protective film on the protective film receiving platform is moved to the part on the product receiving platform by the moving component and the conveying component set on the peeling component and the vibrating plate component. During this process, the protective film on the conveying component is checked by the photo taking component to see if there is any leakage. If there is any leakage, the remaining protective film on the conveying component is blown off. If there is no leakage, it continues to move to the product receiving platform and stick the protective film on the product. The moving component and the conveying component then pick up the part with the protective film and place it on the carrier of the sealing component. The carrier with the part is then sealed by the sealing component. The moving component and the conveying component operate on multiple platforms of the peeling component, the vibrating plate component and the sealing component, which can greatly reduce manual operation and improve work efficiency. (2) By setting two vibratory plates in opposite directions, one vibrating clockwise and the other counterclockwise, the opposing vibration forces of the two vibratory plates can be canceled out, which can greatly reduce the impact on other equipment and reduce the equipment failure rate and production failure rate. (3) After the first pressure sensor at the bottom of the annular telescopic vertical wall of the suction head comes into contact with the protective film receiving platform, the air pump starts under the command of the control module. The control module commands the air pump to be in the first-level suction state with a smaller suction force. When the suction head moves on the vibratory plate assembly, the first pressure sensor at the bottom of the annular telescopic vertical wall first comes into contact with the side wall of the vibratory track, and then the suction head continues to move down until the bottom of the suction head attaches the protective film to the part and the second pressure sensor at the bottom of the suction head comes into contact with the top of the part. Only then will the control module command the air pump to start the second-level suction force and command the telescopic guide column to retract and drive the suction head to move up. On the sealing assembly, after the first pressure sensor at the bottom of the annular telescopic vertical wall comes into contact with the carrier belt and is subjected to force, the telescopic guide column stops moving. Under the action of the force pulse signal of the first pressure sensor, the air pump switches to the first-level suction state, so that the first-level suction force is insufficient to pick up the part and the part falls onto the carrier belt.

[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0020] like Figures 1-12As shown, an automatic film-applying and packaging device of the present invention includes a frame and a peeling assembly 1, a vibratory feeder assembly 2, a moving assembly 4, a conveying assembly 5, a photographing assembly 6, and a sealing assembly 3 disposed within the frame. The moving assembly 4 includes two X-axis gantry frames 401 disposed on both sides of the peeling assembly 1. The peeling assembly 1 and the vibratory feeder assembly 2 are disposed side by side below the conveying assembly 5. The sealing assembly 3 is disposed at the front end of the peeling assembly 1 and the vibratory feeder assembly 2. The photographing assembly 6 is disposed between the peeling assembly 1 and the vibratory feeder assembly 2. The peeling assembly 1 is used to peel the protective film off the slip paper. On the receiving platform 108, the vibratory feeder assembly 2 is used to transport the part 506 to the product receiving platform 201. The conveying assembly 5 includes a suction head 504, a sensor and an air pump. The air pump is connected to the suction head 504. The air pump switches the suction strength according to the sensor data to sequentially pick up the protective film through the suction head 504 and stick it to the part 506, and pick up the part 506 with the protective film pasted on and move it to the carrier belt of the sealing assembly 3. The photographing assembly 6 is used to detect the state of the protective film picked up by the conveying assembly 5. The sealing assembly 3 is used to seal the carrier belt on which the part 506 is placed. To simultaneously perform screening, arrangement, protective film application, and packaging, the protective film on the slip paper is first peeled off by the peeling component 1 and placed onto the protective film receiving platform 108. Simultaneously, the vibratory feeder component 2 transports the part 506 to the product receiving platform 201. Then, the moving component 4 and the conveying component 5, mounted on the peeling component 1 and the vibratory feeder component 2, move the protective film from the protective film receiving platform 108 onto the part 506 on the product receiving platform 201. During this process, the photographing component 6 checks whether the protective film on the conveying component 5 is in good condition. If any part is missed, the remaining protective film on the transport component 5 is blown off. If there is no missed, the component continues to move to the product receiving platform 201, where the protective film is applied to the product. The moving component 4 and the transport component 5 then pick up the part 506 with the protective film and place it on the carrier belt of the sealing component 3. The sealing component 3 then seals the carrier belt containing the part 506. By operating the moving component 4 and the transport component 5 on multiple platforms, including the peeling component 1, the vibratory feeder component 2, and the sealing component 3, manual operation can be greatly reduced and work efficiency can be improved.

[0021] Specifically, the stripping assembly 1 includes a support frame. A material tray 101 is connected to the rear end of the support frame via a support arm. The material tray 101 contains a roll of slip paper with a protective film adhered to it. A brake arm 102 is mounted on the support frame, which abuts against the material tray 101 to prevent the material tray 101 from rotating too quickly. A material feeding support plate 103, a feeding seat 105, a stripping plate 107, and a protective film receiving platform 108 are sequentially arranged on the side of the support frame. Above the feeding seat 105 is a... The device includes a clamping cylinder 104 and a pressing cylinder 106. The feeding seat 105 can move back and forth under the action of a motor. The clamping cylinder 104 moves downwards to press the slip paper onto the feeding seat 105, while the feeding seat 105 moves forward until it abuts against the peeling plate 107. Then, the pressing cylinder 106 presses the slip paper onto the peeling plate 107. Afterwards, the clamping cylinder 104 separates from the feeding seat 105, and the feeding seat 105 moves backwards. This reciprocating motion is used to convey the slip paper forward. The front end of the peeling plate 107 is a downward-facing bevel. The slip paper passes through the gap between the peeling plate 107 and the protective film receiving platform 108, adheres to the bevel, and moves downwards. It then abuts against the rim surfaces of the driven wheel 109 and the pressing wheel 110 and wraps around the take-up wheel 111, which is equipped with a motor. The recycling of the slip paper is achieved by the rotation of the receiving wheel 111. When the slip paper passes through the gap between the peeling plate 107 and the protective film receiving platform 108, the protective film on the slip paper separates from the slip paper due to the downward bending angle of the slip paper and moves to the protective film receiving platform 108. The slip paper is then recycled on the receiving wheel 111 after passing through the driven wheel 109 and the pressure wheel 110.

[0022] Since the peeling assembly 1, vibratory feeder assembly 2, photographing assembly 6, and sealing assembly 3 are located in different positions, the protective film and parts 506 need to be moved to the corresponding positions by the moving assembly 4 according to the positions of different devices. Therefore, in one embodiment, the moving assembly 4 also includes an X-axis motor, a Y-axis connecting plate 402, a Y-axis motor, a Y-axis track, and a Z-axis connecting plate 403. The X-axis motor is mounted on one of the X-axis gantry frames 401. The bottom sides of the Y-axis connecting plate 402 are horizontally slidably connected to the X-axis track on the X-axis gantry frame 401. The Y-axis motor and the Y-axis track are mounted on the Y-axis connecting plate 402. The Z-axis connecting plate 403 is vertically slidably mounted on the Y-axis track. The conveying assembly 5 is mounted on the Z-axis connecting plate 403. The conveying assembly 5 is used to pick up the protective film and parts 506. The X-axis motor is used to drive the Y-axis connecting plate 402 to move horizontally, and the Y-axis motor is used to drive the Z-axis connecting plate 403 to move vertically. Specifically, the two legs of the two X-axis gantry frames 401 are connected inside the machine frame. An X-axis track is installed on the top of the X-axis gantry frame 401. Slider blocks that are slidably connected to the X-axis track are installed at both ends of the Y-axis connecting plate 402. An X-axis lead screw is driven to the output shaft of the X-axis motor, and the lead screw is rotatably connected to the threaded connection on the slider of the Y-axis connecting plate 402. When the X-axis motor rotates, the Y-axis connecting plate 402 moves back and forth via the X-axis motor. Similarly, when the Y-axis motor rotates, the Z-axis connecting plate 403 moves left and right via the Y-axis motor. By setting the conveying component 5 on the moving component 4, the moving component 4 enables the conveying component 5 to move horizontally. Since the moving component 4 is positioned above the stripping component 1, the vibratory feeder component 2, and the sealing component 3, the movement of the moving component 4 allows the protective film and parts 506 to be transported to the corresponding equipment according to the production steps. The coordinated use of multiple devices can greatly improve production efficiency.

[0023] After the protective film is peeled off from the slip paper by the peeling component 1, the bottom surface of the protective film generally has a certain degree of stickiness in order to adhere to the surface of the part 506. Therefore, after the protective film is peeled off, it is easy for the protective film to stick to the protective film receiving platform 108, making it difficult for the conveying component 5 to pick up the protective film. In order to improve production efficiency, a conveying component 5 generally includes multiple suction heads 504. Multiple protective films arranged in sequence are picked up at one time by multiple suction heads 504. Therefore, when there is a missed pick-up, all the protective films that have been picked up can only be blown off and the protective films can be picked up again, which is prone to a high failure rate. Therefore, in order to reduce the failure rate of picking up the protective film, in one embodiment, the upper surface of the protective film receiving platform 108 of the peeling component 1 is a serrated surface, and a through groove is opened in the picking area of ​​the protective film receiving platform 108. By setting the surface of the protective film receiving platform 108 to a serrated surface, the contact area between the surface of the protective film receiving platform 108 and the protective film is reduced, changing from surface contact to multiple line contacts. This greatly reduces the adhesive force of the protective film on the protective film receiving platform 108, reduces the difficulty for the transport component 5 to pick up the protective film, and improves the success rate. Simultaneously, since the transport component 5 uses negative pressure suction to temporarily hold the protective film on it, to prevent the negative pressure generated by the transport component 5 when picking up the protective film from exerting suction on the protective film receiving platform 108, a through-groove is provided on the protective film receiving platform 108. After the peeling component 1 peels the protective film from the slip paper, part of the protective film will remain in the through-groove area. When the transport component 5 moves to this position, air enters from the bottom, making it easier to pick up the protective film and also preventing the transport component 5 from exerting suction on the protective film receiving platform 108.

[0024] Since the conveying assembly 5 is equipped with multiple suction heads 504 for absorbing the protective film, and the vibratory plate 202 for arranging the parts 506 in the same upward direction has a low discharge efficiency, in order to enable the vibratory plate 202 to meet the feeding requirements, in one embodiment, the vibratory plate assembly 2 includes two vibratory plates 202, a vibratory track 203 and a straight vibrator 204. The two vibratory plates 202 are arranged opposite to each other and their output ports are connected to the vibratory track 203. A straight vibrator 204 is arranged below the vibratory track 203. A product receiving platform 201 is arranged at the end of the vibratory track 203. A receiving plate 205 is arranged on the product receiving platform 201, and a receiving groove 206 is opened on the receiving plate 205. Two vibratory feeders 202 are independent of each other and arranged in opposite directions, so that their discharge ports are in close proximity. Vibration tracks 203 are installed at the discharge ports of both feeders. After the feeders discharge, the parts 506 are vibrated onto the vibration tracks 203 and then transported to the product receiving platform 201. Since the parts 506 lose vibration force after the feeders discharge, a linear vibrator 204 is installed at the bottom of the vibration tracks 203 to drive the movement of the parts 506. The working principle of the vibratory feeders 202 is existing technology and will not be described in detail here. Because the vibratory feeder 202 generates significant vibration during operation, and its vibration force is unidirectional (clockwise or counterclockwise), the combined vibration of two vibratory feeders 202 typically results in an even greater vibration force. When the vibratory feeder assembly 2, the peeling assembly 1, the moving assembly 4, and the sealing assembly 3 are all located within the same frame, the vibration of the two vibratory feeders 202 can severely impact the operation of other equipment. Furthermore, the vibration can easily cause the protective film to fall off the conveying assembly 5. To avoid the impact of the vibratory feeder assembly 2 on other equipment, the two vibratory feeders 202 are positioned in opposite directions, with one vibrating clockwise and the other counterclockwise. The opposing vibration forces of the two vibratory feeders cancel each other out, significantly reducing the impact on other equipment and lowering equipment failure and production failure rates.

[0025] In one embodiment, the sealing assembly 3 includes a sealing platform with a guide rail for placing the carrier tape. A limiting plate 307 is provided on the guide rail, and a feeding groove 308 is formed on the limiting plate 307. The sealing platform also includes a tension adjustment mechanism 303 for adjusting the tension of the carrier tape. The feeding groove 308 abuts against a second pressure sensor at the bottom of the suction head 504 to switch the suction level and release the part 506 onto the carrier tape below the feeding groove 308.

[0026] In one embodiment, the conveying assembly 5 includes a cylinder mounting plate 502, which is connected to the side of the Z-axis connecting plate 403. A variable pitch cylinder 501 and an air pump are provided on the cylinder mounting plate 502. A plurality of telescopic guide posts 503 are connected to the variable pitch cylinder 501. Each telescopic guide post 503 is connected to a suction head 504. The air pump is connected to each suction head 504. A spring and an annular telescopic vertical wall 505 are provided inside the suction head 504. The spring is used to push the annular telescopic vertical wall 505 to extend out of the bottom of the suction head 504. The bottom area of ​​the suction head 504 surrounded by the annular telescopic vertical wall 505 forms a negative pressure picking port for picking up protective film and parts 506 with protective film pasted on. Because it is equipped with several telescopic guide posts 503 and suction heads 504, it can simultaneously pick up multiple protective films. When used for the production of different parts 506, the sizes of the different parts 506 are different, so the spacing between the multiple telescopic guide posts 503 and suction heads 504 needs to be different. Therefore, by connecting several telescopic guide posts 503 to a pitch-changing cylinder 501, the spacing between the multiple telescopic guide posts 503 can be adjusted through the pitch-changing cylinder 501. The air pump on the cylinder mounting plate 502 is connected to each suction head 504 to provide suction force to the suction head 504 to pick up the protective film and the part 506. The suction head 504 has an annular telescopic vertical wall 505 at its bottom, and an annular groove at its bottom, allowing the annular telescopic vertical wall 505 to slide within the groove. A spring is located at the top of the annular telescopic vertical wall 505 within the groove, allowing the annular telescopic vertical wall 505 to extend beyond the bottom of the suction head 504. The negative pressure picking area in the middle of the annular telescopic vertical wall 505 can limit the movement of the protective film and the part 506, preventing them from deviating after being sucked up.

[0027] Furthermore, a first pressure sensor is provided at the bottom of the annular telescopic vertical wall 505, and a second pressure sensor is provided at the bottom of the suction head 504. The control module is used to instruct the air pump to start the first-level suction when the first pressure sensor or the second pressure sensor is subjected to force alone, instructing the air pump to start the second-level suction to adsorb the protective film and release the part 506. When the annular telescopic vertical wall 505 retracts and both the first and second pressure sensors are subjected to force, the control module instructs the air pump to start the second-level suction to adsorb the part 506. The telescopic guide column 503 stops moving downward as the air pump state switches. Since the actions that the conveying component 5 needs to perform on the stripping component 1, the vibratory feeder component 2 and the sealing component 3 are different, the telescopic guide column 503 needs to perform different actions according to different equipment. When the conveying component 5 is on the peeling component 1, since it only needs to cover the protective film through the annular telescopic vertical wall 505, in order to prevent the protective film from sticking to the protective film receiving platform 108, it stops moving downward after the first pressure sensor at the bottom of the annular telescopic vertical wall 505 contacts the protective film receiving platform 108, so as to prevent the bottom of the suction head 504 from abutting against the protective film and causing the protective film to stick to the protective film receiving platform 108. After the conveying component 5 picks up the protective film and moves it to the product receiving platform 201, since it is necessary to stick the protective film to the part 506, in order to avoid multiple parts 506 being kept neat on the product receiving platform 201 so that multiple protective films can be pasted at the same time, the product receiving platform 201 is provided with a receiving plate 205. The receiving plate 205 has a receiving groove 206, which is used for multiple suction heads 504 to extend into. After the suction head 504 of the conveying component 5 reaches above the receiving trough 206, the suction head 504 continues to move downward. After the first pressure sensor at the bottom of the annular telescopic vertical wall 505 contacts the track side wall below the receiving trough 206, the telescopic guide post 503 continues to move downward until the bottom of the suction head 504 in the middle of the annular telescopic vertical wall 505 abuts against the surface of the part 506 and stops. At this time, the protective film is stuck to the surface of the part 506 under the abutting action of the bottom of the suction head 504. Since the second pressure sensor is located on the contact surface of the suction head 504, when the protective film is pasted onto the part 506, the annular telescopic vertical wall 505 also retracts into the suction head 504, so that the first and second pressure sensors are on the same plane and both bear the force. Therefore, after both the first and second pressure sensors bear the force, the telescopic guide post 503 returns to its upward position. After the action of pasting the protective film onto the part 506 is completed, the suction head 504 moves to the top of the sealing assembly 3. Since the carrier tape is also provided with a guide rail on the sealing assembly 3 to guide the movement direction of the carrier tape, and a limit plate 307 is provided above the carrier tape for vertical movement... To facilitate the placement of the part 506 after the protective film is applied, a feeding groove 308 is provided on the limiting plate 307. After the suction head 504 moves above the feeding groove 308, it moves downward until the annular telescopic vertical wall 505 extends into the feeding groove 308, and the second pressure sensor on the suction head 504 stops moving after being stressed. Since the bottom elevation of the part 506 is close to or flush with the bottom elevation of the annular telescopic vertical wall 505 after the part 506 is picked up, if it continues to move downward, the part 506 will be damaged after being stressed. Therefore, after the second pressure sensor is stressed and the part 506 is placed on the carrier belt, the conveying assembly 5 resets.Since the moving component 4 and the conveying component 5 only need to perform three actions—picking up the protective film on the peeling component 1, pasting the protective film onto the part 506 on the vibratory feeder component 2 and picking up the part 506, and placing the part 506 on the carrier belt on the sealing component 3—the control module cycles through these three actions as one cycle.

[0028] Furthermore, since the air pump needs to be turned off before suctioning the protective film to prevent it from being sucked up as the suction head 504 approaches, and since the projection surfaces of the suction head 504 and the protective film are not completely aligned at this point, the sucked-up protective film is highly likely to be in a skewed state. Therefore, the air pump needs to be kept off before the suction head 504 approaches the protective film. Only when the suction head 504 reaches the designated position—that is, after the first pressure sensor at the bottom of the annular telescopic vertical wall 505 at the bottom of the suction head 504 comes into contact with the protective film receiving platform 108—does the air pump start under the command of the control module. And because the protective film is lightweight and easily deformed under suction, the air pump can only be operated at a lower suction level (Level 1) by the command of the control module. The state; when the suction head 504 moves on the vibratory feeder assembly 2, two actions need to be commanded: one is to attach the protective film to the part 506, and the other is to pick up the part 506. Since the top of the part 506 below the receiving groove 206 is slightly higher than the bottom of the annular telescopic wall 505, after the suction head 504 gradually moves down, the first pressure sensor at the bottom of the annular telescopic wall 505 first abuts against the side wall of the vibratory track 203 to receive the force, and then the suction head 504 continues to move down until the bottom of the suction head 504 attaches the protective film to the part 506 and the second pressure sensor at the bottom of the suction head 504 abuts against the top of the receiving groove 206 to receive the force. Only then will the control module command the air pump to start the secondary suction and command the telescopic guide column 503 to retract to drive the suction head 504 to move up. Furthermore, the first and second pressure sensors provide pulse signals to the control module. Each time force is applied, a pulse signal is output to the control module, so that the pulse action of the first and second pressure sensors can enable the control module to instruct the air pump to maintain its state until the next pulse action of the first and second pressure sensors, after which the state is changed and the next action is executed.

[0029] The function of switching between two different suction forces by instructing the air pump through the first and second pressure sensors is due to the different actions performed by the transport assembly 5 on the peeling assembly 1, the vibratory feeder assembly 2, and the sealing assembly 3, and the different weights of the protective film and the part 506. When the transport assembly 5 is at the peeling assembly 1, since the protective film needs to be lifted and is relatively light, it can be lifted using only primary suction. However, at the vibratory feeder assembly 2, since two actions are required—applying the protective film and lifting the part 506—and the part 506 is heavier, the action of applying the protective film to the part 506 causes both the first and second pressure sensors to be stressed. This stress on the two sensors switches the air pump's suction force. After the film application is complete, the air pump provides a stronger secondary suction force to lift the part 506 and move it above the sealing assembly 3 via the transport assembly 5. On the sealing assembly 3, the... The part 506 needs to be placed on the carrier belt, and the depth of the feeding groove 308 on the feeding plate is just enough for the annular telescopic vertical wall 505 to extend into it. After the second pressure sensor at the bottom of the suction head 504 abuts against the top of the feeding groove 308 and is subjected to force, the telescopic guide column 503 stops moving. Under the action of the force pulse signal of the second pressure sensor, the air pump switches to the first-level suction state, so that the first-level suction is insufficient to pick up the part 506, causing the part 506 to fall onto the carrier belt. In order to make the first-level suction able to pick up the protective film but not the part 506, the force of the first-level suction needs to be greater than the weight of the protective film but less than the weight of the part 506.

[0030] Furthermore, the sealing platform has a carrier tape feeding tray 301 and a carrier tape receiving tray 302 at both ends of the guide rail for releasing and retrieving the carrier tape bottom plate. A film-coating material placement mechanism 304 is provided above the guide rail for releasing the carrier tape cover plate. A roller 306 seat is provided on the sealing platform below the film-coating material placement mechanism 304. A roller 306 is rotatably mounted on the roller 306 seat. A ratchet 305 is coaxially connected to the roller 306. An abutment rod that interferes with the cylinder mounting plate 502 is arranged in a ring array on the outer side of the ratchet 305. The cylinder mounting plate 502 descends and pushes the abutment rod to drive the ratchet 305 and the roller 306 to rotate. The roller 306 rotates and the teeth apply pressure to the stacked carrier tape cover plate and carrier tape bottom plate to close them and push the carrier tape forward. A film-coating material hot pressing mechanism 309 is provided on the sealing platform at the rear end of the roller 306 for sealing the closed carrier tape cover plate and carrier tape bottom plate. The carrier tape bottom plate is released from the carrier tape unloading tray 301. After the part 506 is placed on the carrier tape bottom plate, the carrier tape cover plate released from the coating material placement mechanism 304 stacks on top of the carrier tape bottom plate below it. Under the action of the carrier tape take-up tray 302, they move synchronously to the rear end. Under the rotation of the ratchet 305, the ratchet teeth close the carrier tape cover plate and the carrier tape bottom plate. In order to enable the carrier tape unloading tray 301, the carrier tape take-up tray 302, the coating material placement mechanism 304, and the coating material hot pressing mechanism 309 to move synchronously with the handling assembly 5, the carrier tape unloading tray 301, the carrier tape take-up tray 302, the coating material placement mechanism 304, and the coating material hot pressing mechanism 309 are all electrically connected to the control module. The equipment on the moving assembly 4, the vibratory feeder assembly 2, and the stripping assembly 1 are also electrically connected to the control module. Because the recorder can rotate in one direction, and only rotates when the cylinder mounting plate 502 descends under the downward pushing action of its side wall, each time the cylinder mounting plate 502 descends, it pushes the ratchet 305 to rotate once, and the ratchet 305 drives the roller 306 to rotate once. This can push the carrier tape cover plate and carrier tape bottom plate cover located below the roller 306 to move once. When the cylinder mounting plate 502 rises and resets, the ratchet 305 spins freely and does not drive the roller 306 to rotate.

[0031] A third pressure sensor is provided on the forward rotation contact surface of several contact rods of ratchet 305 for contacting the cylinder mounting plate 502 to receive force. The control module instructs the peeling assembly 1 to peel the protective film on the slip paper onto the protective film receiving platform 108 according to the pressure data of the third pressure sensor. When the cylinder mounting plate 502 descends and triggers the third pressure sensor, the count in the control module is cleared. After the cylinder mounting plate 502 completes the action, it will reset and return to the top of the peeling assembly 1 to prepare for the next action.

[0032] Furthermore, the camera component 6 is electrically connected to the control module. The camera component 6 is used to acquire the status of the protective film being sucked up on several suction heads 504. The control module is used to instruct the air pump to stop starting when the camera component 6 acquires that several suction heads 504 are leaking suction. When the suction head 504 is detected to be leaking suction, the air pump is turned off to blow off the protective film on some suction heads 504 that are not leaking suction and to re-absorb the protective film.

[0033] Working principle: The material tray 101 on the peeling assembly 1 slides the slippery paper with protective film along the material feeding support plate 103, feeding seat 105, peeling plate 107 and protective film receiving platform 108 in sequence by the gradual rotation of the receiving roller 111. When the peeling plate 107 is stopped, the protective film falls off the slippery paper and is placed on the protective film receiving platform 108. Meanwhile, the two vibrating plates 202 of the vibrating plate assembly 2 screen the parts 506 into the same direction and then transport the parts 506 from the vibrating track 203 to the product receiving platform 201 through the vibrating track 203 and the straight vibrator 204. Under the suction of the first stage of the air pump, the moving assembly 4 and the conveying assembly 5 pick up the protective film from the protective film receiving platform 108 and move it to the product receiving platform 201. The device moves in one direction. During the movement, the camera component 6 below detects whether there are any missed suctions on the suction heads 504. After the transport component 5 moves to the product receiving platform 201, the transport component 5 moves downward and attaches the protective film to the part 506. Under the action of secondary suction, the part 506 is sucked up and moved towards the sealing component 3. After moving to the material discharge trough 308, the transport component 5 moves downward and switches to primary suction after the first pressure sensor is stressed, causing the part 506 to fall onto the carrier tape base plate. After the carrier tape cover plates released by the film placement mechanism 304 are stacked together, the carrier tape cover plates and the carrier tape base plate are covered by the ratchet 305. The film is then sealed by the film hot pressing mechanism 309 and collected on the carrier tape receiving tray 302.
