Description

Technical Field

[0001] This application relates to the field of automated production line technology, and more specifically, to a collection mechanism and collection device. Background Technology

[0002] In the process of collecting release film, traditional methods mainly involve vacuuming the release film into a collection box or directly throwing it into the box. However, because release film is extremely lightweight, it is prone to scattering. Furthermore, some types of release film contain adhesive that can adhere to the collection device during the collection process, affecting the operation of other mechanisms. Utility Model Content

[0003] In view of this, this application provides a collection mechanism and collection device to solve the problem of low collection success rate of release film.

[0004] One embodiment of this application provides a collection mechanism for collecting waste. The collection mechanism includes a base, a feeder, a collector, and a tray. The feeder is rotatably disposed on the base. The collector is also rotatably disposed on the base. A strip of material from the tray is wound around the feeder. One end of the strip is connected to the collector. The strip has an adhesive surface for adhering waste. When the feeder rotates, at least a portion of the strip unwinds, allowing the adhesive surface to adhere waste. When the collector rotates, at least a portion of the strip rewinds, causing the adhered waste to rewind as well.

[0005] Once waste is peeled or torn from the product, the collection mechanism is positioned along the path the waste would take. First, one end of the conveyor belt is attached to the collector. As the collector rotates, the conveyor belt moves from the feeder to the collector. The waste adheres to the bonding surface and is wound up with the conveyor belt into the collector, completing the waste collection. The tray containing the waste is then discarded and replaced with a new tray. This collection mechanism improves the success rate of waste collection and effectively prevents peeled waste from interfering with the operation of other mechanisms.

[0006] In some embodiments, the collecting mechanism further includes a drive component. The drive component is used to drive the collecting component to rotate and thus drive the feeding component to rotate. After connecting one end of the material belt to the collecting component, the drive component is activated.

[0007] In some embodiments, the collecting mechanism further includes a damping component. The damping component is used to apply a force to the feeder to increase the frictional force that resists rotation of the feeder.

[0008] The damping component effectively prevents the feeder from rotating too fast, thus avoiding excessive tension on the conveyor belt and potential breakage. The damping component allows the feeder to rotate at a relatively stable speed, ensuring that the adhesive surface of the conveyor belt collects as much waste material as possible.

[0009] In some embodiments, the damping assembly includes a friction element, a fixing element, an elastic element, and an adjusting element. The friction element is slidably connected to the base. The friction element applies rotational damping to the feed element. The fixing element is fixed to the base and spaced apart from the friction element. The elastic element is disposed between the friction element and the fixing element. The elastic element applies a force to the friction element to move the friction element toward the feed element, thereby applying rotational damping to the feed element. The adjusting element changes the distance between the fixing element and the friction element to adjust the magnitude of the force applied by the elastic element to the friction element.

[0010] The friction element can act on the rotating shaft of the feeder. By adjusting the compression of the elastic element, the magnitude of the force exerted by the elastic element on the friction element can be changed. A larger force results in greater rotational damping exerted by the friction element on the feeder, and vice versa. The friction element can also act on the feed strip in the tray. As the feed strip unwinds from the feeder and is then wound up by the collector, the friction element moves towards the feed strip on the feeder due to the force exerted by the elastic element. This ensures that the friction element remains in contact with the feed strip, thus applying rotational damping to the feeder. The damping assembly effectively ensures that the feeder rotates at a relatively stable speed.

[0011] In some embodiments, the feeding component includes a feeding wheel shaft and a clamping member. The feeding wheel shaft is rotatably mounted on a base. The clamping member is connected to the circumferential sidewall of the feeding wheel shaft and is movable relative to the feeding wheel shaft in the radial direction of rotation of the feeding wheel shaft. A material tray is rotatably connected to the feeding wheel shaft. The clamping member applies a force to the material belt to prevent the material belt from rotating relative to the feeding wheel shaft.

[0012] The clamping element applies a force to the belt to prevent the belt from rotating relative to the feed wheel shaft. This helps to ensure that the belt maintains tension as it moves from the feeder to the collector, thus achieving a smooth feeding process until the belt is completely wound into the collector.

[0013] In some embodiments, the collecting device includes a collecting wheel axle and a connector. The collecting wheel axle is rotatably mounted on a base. The connector is disposed on the collecting wheel axle. The connector is used to fix one end of the material belt to the collecting wheel axle so that the material belt is wound up when the collecting wheel axle rotates.

[0014] The connector effectively ensures that the material belt is wound up on the collector when it rotates, which helps prevent the material belt from falling off the collector.

[0015] In some embodiments, the connector includes a first connecting portion and a second connecting portion. A fixing groove is provided on the circumferential sidewall of the collecting wheel shaft. The first connecting portion is connected to the collecting wheel shaft. The second connecting portion engages with the groove wall of the fixing groove to clamp the material belt.

[0016] The second connecting part can effectively prevent the material belt from falling off the collector. As the collector rotates, the material belt with waste material adhering to it can be tightly wound into the collector.

[0017] In some embodiments, the collection mechanism further includes a guide. The guide is disposed on the base. The guide is used to guide the movement path of the conveyor belt from the feeder to the collector.

[0018] Setting up guide components can guide the material belt from the feeding component to the collecting component, and can also extend the material belt's movement path, thereby increasing the success rate of waste material being adhered to the bonding surface.

[0019] In some embodiments, the strip also has a non-adhesive side. The non-adhesive side and the adhesive side are disposed opposite to each other. The non-adhesive side faces the guide. The adhesive side is connected to the collector.

[0020] With the non-adhesive surface facing the guide, the surface in contact with the guide during the material belt's movement to the collector is non-adhesive. This reduces friction between the material belt and the guide, helps prevent the material belt from getting stuck due to adhesion, and thus improves the smoothness of the material belt's movement from the feeder to the collector.

[0021] One embodiment of this application provides a collection device, which includes a mounting base and a collection mechanism. The base is detachably connected to the mounting base.

[0022] The collection mechanism and the mounting base are modularly designed. Once the material tape on the tray of a collection mechanism is completely wound into the collection unit, the base can be directly removed from the mounting base and replaced with a collection mechanism equipped with a brand new material tray, which can achieve uninterrupted collection of waste materials.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0031] Embodiments of this application provide a collection mechanism for collecting waste. The collection mechanism includes a base, a feeding component, a collecting component, and a tray. The feeding component is rotatably disposed on the base. The collecting component is also rotatably disposed on the base. A strip of material from the tray is wound around the feeding component. One end of the strip is connected to the collecting component. The strip has an adhesive surface for adhering to waste material. When the feeding component rotates, at least a portion of the strip unwinds and adheres to the waste material. When the collecting component rotates, at least a portion of the strip winds up and winds up the adhered waste material along with it.

[0032] Once waste is peeled or torn from the product, the collection mechanism is positioned along the path the waste would take. First, one end of the conveyor belt is attached to the collector. As the collector rotates, the conveyor belt moves from the feeder to the collector. The waste adheres to the bonding surface and is wound up with the conveyor belt into the collector, completing the waste collection. The tray containing the waste is then discarded and replaced with a new tray. This collection mechanism improves the success rate of waste collection and effectively prevents peeled waste from interfering with the operation of other mechanisms.

[0033] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] Please see Figure 1One embodiment of this application provides a collection mechanism 100 for collecting waste. The collection mechanism 100 includes a base 1, a feeding component 2, a collecting component 3, and a tray 4. The feeding component 2 is rotatably disposed on the base 1. The collecting component 3 is also rotatably disposed on the base 1. A strip 401 of the tray 4 is wound around the feeding component 2. One end of the strip 401 is connected to the collecting component 3. The strip 401 has an adhesive surface for adhering waste. When the feeding component 2 rotates, at least a portion of the strip 401 unwinds, allowing the adhesive surface to adhere waste. When the collecting component 3 rotates, at least a portion of the strip 401 rewinds, causing the adhered waste to rewind as well.

[0035] After waste material is peeled or torn off the product, the collection mechanism 100 is placed in the path the waste material will take. First, one end of the conveyor belt 401 is connected to the collection unit 3. When the collection unit 3 rotates, the conveyor belt 401 moves from the feeder 2 to the collection unit 3. The waste material adheres to the bonding surface and is wound up with the conveyor belt 401 into the collection unit 3, completing the waste material collection. The tray 4 containing the collected waste material is then discarded and replaced with a new tray 4. The collection mechanism 100 can improve the success rate of waste material collection and effectively prevent the peeled waste material from affecting the operation of other mechanisms.

[0036] For some products, waste materials can be common non-adhesive release films or release films with a certain degree of adhesion. For example, some products require the film to cover a certain part of the workpiece in the intermediate process, and then the film needs to be removed in the quality inspection stage. In related technologies, vacuum is often used to suck the peeled (or removed) release film into the receiving box or throw it directly into the receiving box. For release films with a certain degree of adhesion, they may adhere to other positions before entering the receiving box, thus making collection difficult. In the collection mechanism 100 of this application, the material strip 401 of the material tray 4 is unwound from the feeding component 2 and then wound up to the collecting component 3. The release film adheres to the adhesive surface and is wound up together with it to the collecting component 3, improving the success rate of release film collection.

[0037] In some embodiments, the tray 4 is an adhesive tape, and the tape 401 is the tape body. At least one side of the tape body is adhesive, meaning that this side is coated with an adhesive. The adhesive side is the bonding surface, capable of adhering waste materials, such as adhesive release film or non-adhesive release film. The tape body can also be an electrostatic adsorption tape, which can also adhere waste materials to the bonding surface.

[0038] In some embodiments, the collecting mechanism 100 further includes a drive member 5. The drive member 5 is used to drive the collecting member 3 to rotate and drive the feeding member 2 to rotate. After connecting one end of the material belt 401 to the collecting member 3, the drive member 5 can be started.

[0039] In some embodiments, the driving component 5 can drive the collecting component 3 to rotate. Since one end of the material belt 401 is connected to the collecting component 3, when the collecting component 3 rotates, the material belt 401 located on the collecting component 3 will pull the feeding component 2 to rotate, making it easier to keep the material belt 401 taut and preventing the material belt 401 from swinging randomly when the collecting component 3 rotates, so as to accurately adhere waste materials. Alternatively, a transmission mechanism can be provided between the collecting component 3 and the feeding component 2, so that the rotation of the collecting component 3 can drive the rotation of the feeding component 2.

[0040] Please see Figure 1 The driving component 5 can be a flat stepper motor. Both the flat stepper motor and the collecting component 3 are located on the same side of the base 1, and power is transmitted between the flat stepper motor and the collecting component 3 through a gear mechanism. The flat stepper motor has a compact structure, which can effectively reduce the space required for installation.

[0041] In some embodiments, the collecting mechanism 100 further includes a damping component 6. The damping component 6 is used to apply a force to the feeder 2 to increase the frictional force that hinders the rotation of the feeder 2.

[0042] The damping component 6 can effectively prevent the feeder 2 from rotating too fast, so as to prevent the material strip 401 from being subjected to excessive tension and breaking. The damping component 6 can make the feeder 2 rotate at a relatively stable speed, ensuring that the bonding surface of the material strip 401 can collect as much waste material as possible.

[0043] In some embodiments, the damping assembly 6 includes a friction element 61, a fixing element 62, an elastic element 63, and an adjusting element (not shown). The friction element 61 is slidably connected to the base 1. The friction element 61 is used to apply rotational damping to the feed element 2. The fixing element 62 is fixed to the base 1 and spaced apart from the friction element 61. The elastic element 63 is disposed between the friction element 61 and the fixing element 62. The elastic element 63 is used to apply a force to the friction element 61 to move the friction element 61 toward the feed element 2, thereby applying rotational damping to the feed element 2. The adjusting element is used to change the distance between the fixing element 62 and the friction element 61, thereby adjusting the magnitude of the force applied by the elastic element 63 to the friction element 61.

[0044] Friction element 61 can act on the rotating shaft of the feeder 2. The compression of elastic element 63 can be changed by adjusting the adjustment mechanism, thereby altering the force exerted by elastic element 63 on friction element 61. A larger force results in greater rotational damping exerted by friction element 61 on the feeder 2, and vice versa. Friction element 61 can also act on the feed strip 401 of the feed tray 4. As the feed strip 401 unwinds from the feeder 2 and is then wound up by the collector 3, the friction element 61 moves towards the feed strip 401 on the feeder 2 due to the force exerted by elastic element 63. This ensures that friction element 61 remains in contact with the feed strip 401 on the feeder 2, thus applying rotational damping to the feeder 2. The damping assembly 6 effectively ensures that the feeder 2 rotates at a relatively stable speed.

[0045] Please see Figure 1 The friction element 61 has an arc-shaped surface on the side facing the feed element 2. In some embodiments, it can also be a flat surface, as long as the friction element 61 can apply rotational damping to the feed element 2 or the material belt 401. The adjusting element is an adjusting bolt connected to the fixing element 62, and the elastic element 63 is a spring. The spring is sleeved on the shank of the adjusting bolt, which is threaded onto the side of the friction element 61 opposite to the feed element 2. One end of the spring abuts against the fixing element 62, and the other end abuts against the friction element 61, and is compressed between the fixing element 62 and the friction element 61.

[0046] When the friction element 61 acts on the rotating shaft of the feeding element 2, the rotating shaft includes a first shaft section and a second shaft section arranged along its axial direction. The first shaft section is connected to the base 1, and the second shaft section is connected to the material tray 4. The friction element 61 abuts against the first shaft section. Rotating the adjusting bolt compresses the spring, thereby applying a force to the friction element 61. The friction element 61 applies rotational damping to the first shaft section. The magnitude of the rotational damping can be adjusted by adjusting the compression of the spring, so that the damping value applied by the friction element 61 to the feeding element 2 is always relatively stable. When the friction element 61 acts on the material belt 401 of the material tray 4, rotating the adjusting bolt compresses the spring. As the material belt 401 moves from the feeding element 2 to the collecting element 3, the spring can self-adjust, so that the friction element 61 always acts on the material belt 401 located on the feeding element 2, so as to apply rotational damping to the material belt 401.

[0047] In some embodiments, the feeder 2 includes a feed roller shaft 21 and a clamping member 22. The feed roller shaft 21 is rotatably mounted on the base 1. The clamping member 22 is connected to the circumferential sidewall of the feed roller shaft 21 and is movable relative to the feed roller shaft 21 in the radial direction of rotation of the feed roller shaft 21. The material tray 4 is rotatably connected to the feed roller shaft 21. The clamping member 22 is used to apply a force to the material belt 401 to prevent the material belt 401 from rotating relative to the feed roller shaft 21.

[0048] The clamping member 22 applies a force to the material belt 401 to prevent the material belt 401 from rotating relative to the feed wheel shaft 21. This helps to ensure that the material belt 401 maintains tension as it moves from the feed member 2 to the collecting member 3, thereby achieving a smooth feeding process until the material belt 401 is completely wound into the collecting member 3.

[0049] The clamping member 22 can be an elastic structure that can extend and retract radially along the feed wheel shaft 21. The elastic structure is compressed between the material tray 4 (or material belt 401) and the feed wheel shaft 21. The elastic structure can apply a force to the material tray 4 (or material belt 401) to prevent the material tray 4 from rotating relative to the feed wheel shaft 21.

[0050] In some embodiments, the collecting member 3 includes a collecting wheel axle 31 and a connecting member 32. The collecting wheel axle 31 is rotatably disposed on the base 1. The connecting member 32 is disposed on the collecting wheel axle 31. The connecting member 32 is used to fix one end of the material belt 401 to the collecting wheel axle 31 so that the material belt 401 is wound up when the collecting wheel axle 31 rotates.

[0051] The connector 32 can effectively ensure that the material belt 401 can be wound up on the collector 3 when the collector 3 rotates, which helps to prevent the material belt 401 from falling off the collector 3.

[0052] In some embodiments, the connector 32 includes a first connecting portion 321 and a second connecting portion 322. A fixing groove 311 is provided on the circumferential sidewall of the collecting wheel shaft 31. The first connecting portion 321 is connected to the collecting wheel shaft 31. The second connecting portion 322 cooperates with the groove wall of the fixing groove 311 to clamp the material belt 401.

[0053] The second connecting part 322 can effectively prevent the material strip 401 from falling off the collecting member 3. As the collecting member 3 rotates, the material strip 401 with waste material adhering to it can be tightly wound onto the collecting member 3. Figure 1 In the embodiment shown, the bottom wall of the second connecting part 322 and the fixing groove 311 has a certain gap, so that one end of the feeding belt 401 passes through the gap and is fixed to the collecting wheel shaft 31.

[0054] In some embodiments, the collection mechanism 100 further includes a guide 7. The guide 7 is disposed on the base 1. The guide 7 is used to guide the material belt 401 along its movement path from the feeder 2 to the collection unit 3.

[0055] The guide component 7 serves two purposes: first, it guides the material belt 401 from the feeding component 2 to the collecting component 3 along its movement path; second, it extends the movement path of the material belt 401, thereby increasing the success rate of waste material being adhered to the bonding surface.

[0056] In some embodiments, the feed strip 401 also has a non-adhesive surface. The non-adhesive surface and the adhesive surface are disposed opposite to each other. The non-adhesive surface faces the guide 7. The adhesive surface is connected to the collector 3.

[0057] With the non-adhesive surface facing the guide 7, it can be ensured that the surface in contact with the guide 7 during the process of the material belt 401 moving to the collecting part 3 is not sticky. This can reduce the friction between the material belt 401 and the guide 7, and help prevent the material belt 401 from getting stuck due to adhesion, thereby improving the smoothness of the material belt 401 moving from the feeding part 2 to the collecting part 3.

[0058] In some embodiments, the number of guide members 7 is multiple, thereby increasing the area of ​​the conveyor belt 401 for collecting waste. See also Figure 1 The collection mechanism 100 includes two guide members 7, which are positioned along the path of the conveyor belt 401 from the feeder 2 to the collector 3. The collection mechanism 100 also includes a support member 8, which is located on the base 1 and has a guide channel 801 through which the feeder belt 401 passes. The two guide members 7 are spaced apart, and the support member 8 is positioned between the two guide members 7 along the path of the conveyor belt 401, with the guide channel 801 extending in the same direction as the path of the conveyor belt 401.

[0059] When the material strip 401 of the material tray 4 has been completely unwound from the feeding component 2, the tail section of the material strip 401 is no longer under tension. The support component 8 is provided to help prevent the tail section of the material strip 401 from detaching from the guide component 7 under its own weight, so that the tail section of the material strip 401 can effectively collect waste and be smoothly wound into the collecting component 3.

[0060] Please continue reading Figure 1 The collection mechanism 100 also includes a sensor 9, which is located on a guide 7 near the collection unit 3. The sensor 9 is used to sense the material strip 401 passing through the guide 7. When the sensor 9 does not sense the material strip 401 at the guide 7, it means that the material strip 401 has been completely unwound from the feeder 2, and a new tray 4 needs to be replaced, and the tray 4 and waste material located on the collection unit 3 need to be collected (removed).

[0061] Please continue reading Figure 1 One embodiment of this application provides a collection device 200, which includes a mounting base 10 and a collection mechanism 100.

[0062] In some embodiments, the base 1 is detachably connected to the mounting base 10.

[0063] The collection mechanism 100 and the mounting base 10 are modularly designed. When all the material strip 401 of the material tray 4 on a collection mechanism 100 is wound up to the collection component 3, the base 1 can be directly removed from the mounting base 10 and replaced with a collection mechanism 100 equipped with a brand new material tray 4, so that waste can be collected continuously.

[0064] In some embodiments, the mounting base 10 is provided with a groove, the base 1 is slidably connected to the groove, and the base 1 can be disengaged from the mounting base 10 by sliding relative to the mounting base 10 in a disengagement direction. When the base 1 slides relative to the mounting base 10 to the locking position, the relative displacement between the base 1 and the mounting base 10 is restricted.

[0065] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
