[0039] Additionally, the term "and / or" in this article is merely a description of the relationship between related objects; it indicates that three relationships can exist. For example, A and / or B can represent: A existing alone; A and B existing simultaneously; and B existing alone. Furthermore, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0040] It should be understood that in the embodiments of this application, "B corresponding to A" means that B is associated with A; B can be determined based on A. However, it should also be understood that determining B based on A does not mean determining B solely based on A; B can also be determined based on A and / or other information.

[0041] Please see Figures 1 to 5 This application provides an automatic chip 61 recycling device, including: a feeding and conveying unit 1, which includes a movable conveying section; and a milling unit 2, which is located on the output side of the conveying section. The milling unit 2 includes a first moving part 21, a first fixing part 22 located in the moving direction of the first moving part 21, and a milling part 23 located on the side of the first cover plate opposite to the first moving part 21. The first moving part 21 is used to abut the first surface F1 of the card 6 to be recycled against the surface of the first fixing part 22 opposite to the milling part 23. The first fixing part 22 is provided with a first opening K1, which is correspondingly provided with the contacts of the chip 61 of the card 6 to be recycled. The milling part 23 is used to extend into the first opening K1 to open a second opening K2 on the card 6 to be recycled, exposing the contacts of the chip 61. The card 6 to be recycled includes a second surface F2 opposite to the first surface F1, and a chip 61 is disposed on the second surface F2; a separation unit 3 is disposed on the output side of the milling unit 2, and the separation unit 3 includes a second moving part 31, a second fixing part 32 located in the moving direction of the second moving part 31, and an ejection part 33. The second moving part 31 is used to fix the card 6 to be recycled to the second fixing part 32, and the ejection part 33 is used to extend into the second opening K2 to drive the chip 61 to move away from the card body 62 of the card 6 to be recycled, so that the chip 61 and the card body 62 of the card 6 to be recycled are separated; a chip 61 picking unit 4 is disposed on the side of the second fixing part 32 away from the second moving part 31, and the chip 61 picking unit 4 is used to pick up the separated chip 61; a chip 61 placement unit 5 is used to place the recycled chip 61.

[0042] The automatic chip 61 recycling device provided in this embodiment of the invention includes a feeding and conveying unit 1, a milling unit 2, a separation unit 3, a chip 61 picking unit 4, and a chip 61 placement unit 5. The feeding and conveying unit 1 feeds the cards 6 to be recycled and transfers them to the subsequent workstation. The milling part 23 is used to open a second opening K2 on the first surface F1 of the card to be recycled to expose the contacts of the chip 61, so as to facilitate the separation of the chip 61 and the card body 62 in the separation unit 3. The separation unit 3 can use the second opening K2 to push out the chip 61 through the ejection part 33, thereby separating the chip 61 and the card body 62. The milling part 23 can be in the form of a milling drill bit. The chip 61 picking unit 4 is used to pick up the separated chip 61 and place the recycled chip 61. The automatic chip 61 recycling device realizes the fully automatic recycling of the chip 61 in the card to be recycled, which effectively improves the recycling efficiency, has a high degree of automation, replaces manual operation, has high production capacity, and the processing consistency of the automatic chip 61 recycling device is good and the quality is guaranteed.

[0043] In this embodiment, the conveying part in the feeding and conveying unit 1 can be in the form of a conveyor belt, and the milling unit 2, the separation unit 3, the chip 61 picking unit 4 and the chip 61 placing unit 5 can also be connected by a conveyor belt to transport the cards 6 to be recycled. Optionally, the card body 62 is driven on the belt, and two synchronous belts located on both sides of the conveying channel can be used to transport the card body 62, so that when milling or separating operations are performed at each station, the corresponding device under the belt can operate the card body 62.

[0044] The first moving part 21 in the milling unit 2 may include a cylinder, a motor, or other powered components that can move the card 6 to be recycled, so that the extension rod of the cylinder pushes the card 6 to be recycled against the surface of the first fixed part 22 away from the milling part 23. Figure 3 As shown, at this time, the chip 61 in the card 6 to be recycled is located on the lower surface of the card 6 to be recycled, and the contact of the chip 61 is located on the side of the chip 61 body facing the first fixing part 22. Then, the milling part 23 can be inserted into the first opening K1 to open a second opening K2 on the card 6 to be recycled, exposing the contact of the chip 61.

[0045] like Figure 2 As shown, optionally, the milling part 23 can be used to mill grooves at a specified position on the back of the card (the position where the two contacts of the chip 61 are soldered to the copper wire of the card). Preferably, two circular grooves are milled at the soldering position. The grooves are mainly located on the substrate layer of the card body 62. After milling the grooves, the positions of the two contacts of the chip 61 can be seen through the circular grooves.

[0046] Specifically, when the first moving part 21 uses a cylinder, the cylinder moves from bottom to top to push the card onto the first fixing part 22, such as the limiting part on the cover plate, for positioning. The cover plate has a first opening K1 at the position corresponding to the chip 61, so that the milling part 23, such as a milling cutter, can mill a groove at the corresponding position.

[0047] like Figure 3 and 4 As shown, in the separation unit 3, the card 6 to be recycled, which has a second opening K2, can be fixed by the second fixing part 32, and the ejection part 33 can be inserted into the second opening K2 to contact the chip 61 and drive the chip 61 to move away from the card body 62 of the card 6 to be recycled, so that the chip 61 and the card body 62 of the card 6 to be recycled can be separated, so that the chip 61 can be recycled separately.

[0048] Optionally, the ejector 33 may include a servo motor and a push rod controlled by the servo motor. The push rod can move up and down under the drive of the servo motor to eject the chip 61.

[0049] like Figure 5 As shown, after the ejector 33 ejects the chip 61, the chip 61 can be picked up and fixed simultaneously by the chip 61 picking unit 4. That is, the chip 61 picking unit 4 can move downward synchronously with the ejector 33 to hold the chip 61 in place, so as to prevent the chip 61 from falling off. The chip 61 is then transferred to the chip 61 placement unit 5 for placement.

[0050] The discarded cards with chip 61 removed can be transferred to the rear storage box and stacked neatly.

[0051] Please see Figures 6 to 8 In some optional embodiments, the first fixing part 22 is provided with a first limiting part 24 on the side facing the first moving part 21 to fix the card 6 to be recycled.

[0052] It is understandable that the first moving part 21 can restrict the movement of the card 6 to be recycled along the moving direction of the first moving part 21. However, the card 6 to be recycled may slip on the surface of the first fixing part 22, which is not conducive to subsequent milling. Therefore, the first limiting part 24 can be provided to fix the card 6 to be recycled and restrict the card 6 to be recycled to move in a direction parallel to the surface of the first fixing part 22 toward the side of the first moving part 21.

[0053] The first limiting part 24 may be made of components such as baffles, blocks, and bolts.

[0054] Optionally, the first fixing part 22 is provided with at least one first movable limiting part 241 and at least one first fixing limiting part 242 on the side facing the first moving part 21. The first movable limiting part 241 can move in a direction parallel to the surface of the first fixing part 22 facing the first moving part 21 to fix the card 6 to be recycled.

[0055] It should be noted that the first movable limiting part 241 refers to the part that can move relative to the first fixed part 22 to fix cards of different sizes, thereby increasing the applicability. The first fixed part 22 cannot move relative to the first fixed part 22 and can be in the form of a fixing block or a fixing plate, corresponding to fixing one side of the card. Optionally, when the first fixed part 22 adopts a rectangular plate structure, two first movable limiting parts 241 and two first fixed limiting parts 242 can be provided on the side of the first fixed part 22 facing the first moving part 21. The first movable limiting parts 241 and the first fixed limiting parts 242 are arranged opposite to each other and are respectively arranged on one side of the first fixed part 22 to achieve flexible fixing of the card 6 to be recycled.

[0056] Optionally, the first movable limiting part 241 and the first fixed part 22 are slidably connected, and the first movable limiting part 241 includes a first elastic member connected to the first fixed part 22. The first elastic member can be compressed in a direction parallel to the surface of the first fixed part 22 toward the first moving part 21.

[0057] In this embodiment, the first movable limiting part 241 can slide along the surface of the first fixed part 22 toward the first moving part 21, and clamp and fix the card 6 to be recycled by the elastic restoring force of the first elastic member. The first elastic member can be a compression spring or a Z-shaped spring sheet, etc.

[0058] Optionally, the limiting part can also adopt other structural forms. For example, the limiting part can adopt a cylinder-controlled rotating shaft mechanism, which includes at least two rotatable clamping arms, and the clamping and fixing of the side of the card 6 to be recycled can be achieved by rotating the clamping arms.

[0059] Please see Figure 9 In some optional embodiments, the first fixed part 22 is provided with a protective layer 7 away from the first moving part 21, and the protective layer 7 is provided with a third opening K3 that exposes the first opening K1.

[0060] It should be noted that since material fragments may be generated during the use of the milling part 23, which may affect the safety of the user, a protective layer 7 may be provided on the first fixed part 22 away from the first moving part 21, and a third opening K3 that exposes the first opening K1 may be provided, so that the milling part 23 can extend into the protective layer 7 and the first fixed part 22 to achieve milling inside the opening of the protective layer 7 and the first fixed part 22, thereby avoiding material fragments from threatening the safety of the user.

[0061] Optionally, the size of the third opening K3 can be greater than or equal to the size of the first opening K1, as long as the first opening K1 is exposed.

[0062] In some optional embodiments, the second fixing part 32 is provided with at least one second movable limiting part 341 and at least one second fixing limiting part 342 on the side facing the second moving part 31. The second movable limiting part 341 can move in a direction parallel to the surface of the second fixing part 32 facing the second moving part 31 to fix the card 6 to be recycled.

[0063] It is understandable that, similar to the first fixing part 22, the second fixing part 32 can also be provided with a second limiting part. The second limiting part includes a second movable limiting part 341 and a second fixed limiting part 342, so as to flexibly fix the card 6 to be recycled. The second movable limiting part 341 means that it can move relative to the second fixing part 32 to fix cards of different sizes, thereby increasing the applicability. The second fixing part 32 cannot move relative to the first fixing part 22 and can be in the form of a fixing block or a fixing plate, corresponding to fixing one side of the card. Optionally, when the second fixing part 32 adopts a rectangular plate structure, two second movable limiting parts 341 and two second fixed limiting parts 342 can be provided on the side of the second fixing part 32 facing the first moving part 21. The second movable limiting parts 341 and the second fixed limiting parts 342 are arranged opposite each other and are respectively arranged on one side of the second fixing part 32 to achieve flexible fixing of the card 6 to be recycled.

[0064] Please see Figures 3 to 5 Optionally, the second fixing part 32 includes a relief groove K4 for exposing the chip 61.

[0065] It should be noted that, since the ejector part 33 needs to eject the chip 61, in order to avoid the second fixing part 32 affecting the ejection of the chip 61, a clearance groove K4 can be provided at the position of the second fixing part 32 corresponding to the chip 61. When the ejector part 33 acts on the chip 61, the chip 61 can enter the clearance groove K4, while the card body 62 cannot enter the clearance groove K4, so as to achieve separation of the two. When the chip 61 is ejected from the clearance groove K4, it is also convenient for the chip 61 picking unit 4 to accurately adsorb the chip 61.

[0066] Optionally, the chip 61 pickup unit 4 may include a suction cup with gas adsorption holes for adsorbing and fixing the chip 61.

[0067] Please see Figure 10 In some optional embodiments, the chip 61 placement unit 5 includes a tray with a plurality of spaced-apart receiving slots for receiving the chip 61.

[0068] Since each chip 61 is recycled from a different card, the recycled chip 61 can be individually stored in a receiving slot for subsequent repackaging and use.

[0069] In some optional embodiments, the chip 61 automatic recycling device further includes a card thickness detection unit disposed between the feeding and conveying unit 1 and the milling unit 2, a card flipping unit disposed between the milling unit 2 and the separation unit 3, and a card heating unit.

[0070] The card thickness detection unit determines whether the incoming card is a single card or two or more cards stacked together by detecting its thickness. This facilitates subsequent processes. Specifically, the detection head can detect the thickness of the incoming card. If the detected value is greater than the preset thickness value, an alarm will be triggered to prompt the user to take action, ensuring that only a single card to be recycled enters the subsequent process.

[0071] The card flipping unit is designed so that after milling, the side of the card with chip 61 faces down, which makes it inconvenient to push the chip 61 out from the top in the separation unit 3. Therefore, the card flipping unit is used to flip the card 6 to be recycled so that the side of the card with chip 61 faces up.

[0072] Considering that there is also an adhesive bond between the chip 61 and the card body 62 on the same layer, in order to facilitate the separation of the chip 61 and the card body 62, the card heating unit can be used to heat the card so that the adhesive between the chip 61 and the card body 62 melts and the two can be separated.

[0073] In some optional embodiments, the chip 61 automatic recycling device further includes a cutting unit disposed on the side of the second fixed part 32 opposite to the second moving part 31, the cutting unit being used to cut the wire D between the chip 61 and the card body 62.

[0074] Considering that there is usually a wire D connecting the chip 61 and the card body 62, in this embodiment, after the chip 61 is pushed out through the top, the wire D between the chip 61 and the card body 62 can be cut by the cutting unit, and then the chip 61 can be fixed by suction cup.

[0075] The working process of the automatic chip 61 recycling device provided in this application is as follows:

[0076] First, the cards 6 to be recycled are placed into the feeding and conveying unit 1 of the chip 61 automatic recycling device. Then, the cards are conveyed step by step on the conveyor belt of the equipment in the form of individual cards. The card body 62 is placed in reverse, that is, the chip 61 is facing down. First, it enters the card thickness detection unit, and then enters the milling unit 2 to mill grooves at the chip 61 contact points on the back of the card. After being flipped by the card flipping unit, it enters the card heating unit for heating, so that the glue between the chip 61 and the card body 62 melts and the two can be separated. Then it enters the chip 61 separation station, where the chip 61 is pushed out from the two grooves milled on the back of the card (i.e., the second opening K2), and the copper wire connecting the chip 61 and the card is cut. The chip 61 is picked up by the suction cup and placed on the material tray next to it. The waste cards with chip 61 removed are continued to be conveyed to the tail collection box and stacked neatly.

[0077] Please see Figure 11 This invention also provides an automatic recycling method for chip 61, comprising the following steps:

[0078] S110: Place the card 6 to be recycled into the feeding conveying unit 1, which includes a movable conveying section.

[0079] S120: The card 6 to be recycled is fed to the milling unit 2 via the feeding conveying unit 1. The first surface F1 of the card 6 to be recycled is brought into contact with the surface of the first fixing part 22 of the milling unit 2 away from the milling part 23 via the first moving part 21 of the milling unit 2. The first fixing part 22 is provided with a first opening K1, which corresponds to the contact of the chip 61 of the card 6 to be recycled. The milling part 23 in the milling unit 2 is inserted into the first opening K1 to open a second opening K2 on the card 6 to be recycled, exposing the contact of the chip 61. The card 6 to be recycled includes a second surface F2 opposite to the first surface F1, and the chip 61 is disposed on the second surface F2. Figure 2 As shown;

[0080] S130: The card 6 to be recycled is sent to the separation unit 3. The second moving part 31 of the separation unit 3 fixes the card 6 to be recycled to the second fixing part 32 of the separation unit 3, and the ejection part 33 of the separation unit 3 extends into the second opening K2, so as to drive the chip 61 to move away from the card body 62 of the card 6 to be recycled, so as to separate the chip 61 from the card body 62 of the card 6 to be recycled. Figures 3 to 4 As shown;

[0081] S140: The separated chip 61 is picked up by the chip 61 pickup unit 4, such as Figure 5 As shown;

[0082] S150: Place the chip 61 picked up by the chip 61 pickup unit 4 into the chip 61 placement unit 5, such as... Figure 10 As shown.

[0083] The automatic chip 61 recycling method provided in this embodiment of the invention feeds the card 6 to be recycled through the feeding and conveying unit 1, and transfers the card 6 to be recycled to the subsequent station. The milling part 23 is used to open a second opening K2 on the first surface F1 of the card 6 to be recycled to expose the contacts of the chip 61, so as to facilitate the separation of the chip 61 and the card body 62 in the separation unit 3. The separation unit 3 can use the second opening K2 to push out the chip 61 through the ejection part 33 to realize the separation of the chip 61 and the card body 62. The milling part 23 can be in the form of a milling drill bit. The chip 61 picking unit 4 is used to pick up the separated chip 61 and place the recycled chip 61 through the chip 61. The automatic chip 61 recycling device realizes the fully automatic recycling of the chip 61 in the card 6 to be recycled, which effectively improves the recycling efficiency, has a high degree of automation, replaces manual operation, has high production capacity, and the processing consistency of the automatic chip 61 recycling device is good and the quality is guaranteed.

[0084] In step S110, the conveying section of the feeding conveying unit 1 can be in the form of a conveyor belt.

[0085] In step S120, the first moving part 21 in the milling unit 2 can be a component with power, such as a cylinder, that can move the card 6 to be recycled. The extension of the cylinder will push the card 6 to be recycled against the surface of the first fixing part 22 away from the milling part 23. At this time, the chip 61 in the card 6 to be recycled is located on the lower surface of the card 6 to be recycled, and the contact of the chip 61 is located on the side of the chip 61 body facing the first fixing part 22. Then the milling part 23 can be inserted into the first opening K1 to open a second opening K2 on the card 6 to be recycled, exposing the contact of the chip 61.

[0086] Optionally, the milling part 23 can be used to mill grooves at a specified position on the back of the card (the position where the two contacts of the chip 61 are soldered to the copper wire of the card). Preferably, two circular grooves are milled at the soldering position. The grooves are mainly located on the substrate layer of the card body 62. After milling the grooves, the positions of the two contacts of the chip 61 can be seen through the circular grooves.

[0087] Specifically, when the first moving part 21 uses a cylinder, the cylinder moves from bottom to top to push the card onto the first fixing part 22, such as the limiting part on the cover plate, for positioning. The cover plate has a first opening K1 at the position corresponding to the chip 61, so that the milling part 23, such as a milling cutter, can mill a groove at the corresponding position.

[0088] In step S130, the card 6 to be recycled, which has a second opening K2, can be fixed by the second fixing part 32. The ejection part 33 extends into the second opening K2, contacts the chip 61, and moves the chip 61 away from the card body 62 of the card 6 to be recycled, so that the chip 61 and the card body 62 of the card 6 to be recycled are separated, and the chip 61 is recycled separately. Optionally, the ejection part 33 may include a servo motor and a push rod controlled by the servo motor. The push rod can move up and down under the drive of the servo motor to eject the chip 61.

[0089] In step S140, after the chip 61 is ejected by the ejection part 33, the chip 61 can be picked up and fixed by the chip 61 picking unit 4 to prevent the chip 61 from falling off.

[0090] Then in step S150, chip 61 is transferred to chip 61 placement unit 5 by chip 61 pickup unit 4 for placement.

[0091] In some optional embodiments, between the steps of placing the card to be recycled 6 into the feeding conveying unit 1 and sending the card to be recycled 6 to the milling unit 2 through the feeding conveying unit 1, the method further includes: sending the card to be recycled 6 into the card thickness detection unit to determine whether the card to be recycled 6 is a single card; if so, proceed to the next step; if not, execute an alarm action.

[0092] The card thickness detection unit can specifically use a mechanical or optical thickness detector to detect the thickness of the card 6 to be recycled. If the detected value is greater than the preset thickness value, an alarm will be triggered to prompt the user to take action, so as to ensure that a single card 6 to be recycled can enter the subsequent process.

[0093] In some optional embodiments, between the steps of sending the card to be recycled 6 to the milling unit 2 via the feeding and conveying unit 1 and sending the card to be recycled 6 to the separation unit 3, the method further includes: sending the card to be recycled 6 to the card flipping unit to flip the card to be recycled up and down; and sending the flipped card to be recycled 6 to the card heating unit to heat and melt the adhesive material between the chip 61 and the card body 62.

[0094] The card flipping unit is designed so that after milling, the side of the card with chip 61 faces down, which makes it inconvenient to push the chip 61 out from the top in the separation unit 3. Therefore, the card flipping unit is used to flip the card 6 to be recycled so that the side of the card with chip 61 faces up.

[0095] Considering that there is also an adhesive bond between the chip 61 and the card body 62 on the same layer, in order to facilitate the separation of the chip 61 and the card body 62, the card heating unit can be used to heat the card so that the adhesive between the chip 61 and the card body 62 melts and the two can be separated.

[0096] This invention also provides an automatic chip 61 recycling and packaging device, including: an automatic chip 61 recycling device, which is the automatic chip 61 recycling device in any of the above embodiments; and an automatic chip 61 packaging device, used to package the chip 61 recycled by the automatic chip 61 recycling device with a new card body 62.

[0097] It should be noted that the recycled chip 61 can be repackaged and reused through the chip 61 automatic packaging device. The individual chip 61 can be taken out from the chip 61 placement unit 5 of the chip 61 automatic recycling device, soldered to the provided new card body 62, and then packaged.

[0098] The card provided in this application embodiment can specifically be a smart card, which can be used to realize electronic transaction functions. A smart card is a type of card with a predetermined length, width, and thickness, and also features portability and ease of use. A smart card can be a debit card, credit card, stored-value card, public transport card, access card, or membership card, but is not limited to the card types listed above.

[0099] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
