[0042] The chip 61 automatic recovery device provided in the embodiment of the present invention includes a feeding and conveying unit 1, a milling groove 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 is used to feed the material and transfer the card 6 to be recovered to the subsequent workstation. The milling groove portion 23 is used to open a second opening K2 on the first surface F1 of the card 6 to be recovered to expose the contact of the chip 61, so as to facilitate the subsequent separation of the chip 61 and the card body 62 of the card in the separation unit 3. The separation unit 3 can use the second opening K2 through the ejection portion 33 to eject the chip 61 to achieve the separation of the chip 61 and the card body 62 of the card. The milling groove portion 23 can be in the form of a milling groove drill bit, and the chip 61 picking unit 4 is used to pick up the separated chip 61 and place the recovered chip 61 through the chip 61. The chip 61 automatic recovery device realizes the full-automatic recovery of the chip 61 in the card 6 to be recovered, effectively improves the recovery efficiency, has a high degree of automation, replaces manual work, has high production capacity, and the processing consistency of the chip 61 automatic recovery device is good, and the quality is guaranteed.

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

[0044] The first moving part 21 in the slot milling unit 2 may include a cylinder, a motor or other powered component that can drive the card 6 to be recovered to move, so that the card 6 to be recovered is pushed against the surface of the first fixing part 22 away from the slot milling part 23 through the extension rod of the cylinder. 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 contacts of the chip 61 are located on the side of the chip 61 body facing the first fixing portion 22. Then, the milling groove portion 23 can be extended into the first opening K1 to open a second opening K2 on the card 6 to be recycled to expose the contacts of the chip 61.

[0045] like Figure 2 As shown, optionally, the milling portion 23 is used to perform milling at a designated position on the back of the card (the welding position of the two contacts of the chip 61 and the copper wire of the card). Preferably, two circular grooves are milled at the welding position, and the grooves are mainly located on the substrate layer of the card body 62. After milling, the two contact positions of the chip 61 can be seen through the circular grooves.

[0046] Specifically, when the first movable part 21 adopts a cylinder, the cylinder moves from bottom to top to push the card to the first fixed part 22, such as the limiting part on the cover plate for positioning. A first opening K1 is opened at the corresponding position of the cover plate and the chip 61 for the milling part 23, such as a milling cutter, to mill the groove at the corresponding position.

[0047] like Figure 3 and 4 As shown, in the separation unit 3, the card 6 to be recycled with the second opening K2 can be fixed by the second fixing portion 32, and the ejection portion 33 can be extended 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 are separated, so that the chip 61 can be recycled separately.

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

[0049] like Figure 5 As shown, after the ejection part 33 ejects the chip 61, the chip 61 picking unit 4 can be used to pick up and fix the chip 61 simultaneously, that is, the chip 61 picking unit 4 can move downward synchronously with the ejection part 33 to absorb the chip 61 to prevent the chip 61 from falling off, and the chip 61 can be transferred to the chip 61 placement unit 5 through the chip 61 picking unit 4 for placement.

[0050] The waste cards with the chip 61 removed can be further transported to the tail storage box and stacked neatly.

[0051] See also Figures 6 to 8 In some optional embodiments, a first limiting portion 24 is provided on the side of the first fixing portion 22 facing the first moving portion 21 to fix the card 6 to be recycled.

[0052] It can be understood that the first movable portion 21 can limit the movement of the card 6 to be recovered along the moving direction of the first movable portion 21, but the card 6 to be recovered may slip on the surface of the first fixed portion 22, which is not conducive to subsequent milling. Therefore, a first limiting portion 24 can be set to fix the card 6 to be recovered and limit the movement of the card 6 to be recovered in a direction parallel to the first fixed portion 22 toward the side surface of the first movable portion 21.

[0053] The first limiting portion 24 can be a baffle, a block, a bolt or other components.

[0054] Optionally, at least one first movable limiting portion 241 and at least one first fixed limiting portion 242 are provided on the side of the first fixed portion 22 facing the first movable portion 21, and the first movable limiting portion 241 can move in a direction parallel to the surface of the first fixed portion 22 toward the first movable portion 21 to fix the card 6 to be recycled.

[0055] It should be noted that the first movable limiting portion 241 refers to a portion that can move relative to the first fixed portion 22 so as to fix cards of different sizes and increase the scope of application, while the first fixed portion 22 cannot move relative to the first fixed portion 22. A fixed block or a fixed plate may be used to fix a certain side of the card. Optionally, when a rectangular plate structure is adopted in the first fixed portion 22, two first movable limiting portions 241 and two first fixed limiting portions 242 may be set on the side of the first fixed portion 22 facing the first movable portion 21. The first movable limiting portion 241 and the first fixed limiting portion 242 are arranged opposite to each other and respectively correspond to one side of the first fixed portion 22 to realize flexible fixation of the card 6 to be recycled.

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

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

[0058] Optionally, the limiting part may also adopt other structural forms. For example, the limiting part may adopt a cylinder-controlled rotating shaft mechanism, which includes at least two rotatable clamping arms, and the side of the card 6 to be recovered is clamped and fixed by the rotation of the clamping arms.

[0059] See also Fig. 9 In some optional embodiments, the first fixed portion 22 is provided with a protective layer 7 away from the first movable portion 21 , and the protective layer 7 is provided with a third opening K3 exposing the first opening K1 .

[0060] It should be noted that, since material fragments may be generated during the use of the milling groove portion 23, which may affect the safety of the user, a protective layer 7 may be provided on the first fixed portion 22 away from the first movable portion 21, and a third opening K3 exposing the first opening K1 may be provided, so that the milling groove portion 23 can extend into the protective layer 7 and the first fixed portion 22, so as to realize milling grooves inside the openings of the protective layer 7 and the first fixed portion 22, thereby avoiding material fragments from posing a threat to the safety of the user.

[0061] Optionally, the size of the third opening K3 may 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, at least one second movable limiting portion 341 and at least one second fixed limiting portion 342 are provided on the side of the second fixed portion 32 facing the second movable portion 31, and the second movable limiting portion 341 can move in a direction parallel to the surface of the second fixed portion 32 facing the second movable portion 31 to fix the card 6 to be recycled.

[0063] It is understandable that, similar to the first fixed portion 22, the second fixed portion 32 may also be provided with a second limiting portion. The second limiting portion includes a second movable limiting portion 341 and a second fixed limiting portion 342, so as to flexibly fix the card 6 to be recycled. The second movable limiting portion 341 refers to a portion that can be moved relative to the second fixed portion 32, so as to fix cards of different sizes and increase the scope of application, while the second fixed portion 32 cannot be moved relative to the first fixed portion 22, and may be in the form of a fixed block or a fixed plate, corresponding to a certain side of the fixed card. Optionally, when the second fixed portion 32 adopts a rectangular plate structure, two second movable limiting portions 341 and two second fixed limiting portions 342 may be provided on the side of the second fixed portion 32 facing the first movable portion 21, and the second movable limiting portion 341 and the second fixed limiting portion 342 are arranged relative to each other, and are respectively arranged corresponding to one side of the second fixed portion 32, so as to realize the flexible fixation of the card 6 to be recycled.

[0064] See also Figures 3 to 5 Optionally, the second fixing portion 32 includes an avoidance groove K4 for exposing the chip 61 .

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

[0066] Optionally, the chip 61 picking unit 4 may include a suction cup, and the suction cup is provided with a gas adsorption hole for adsorbing and fixing the chip 61 .

[0067] See also Fig.10 In some optional embodiments, the chip 61 placement unit 5 includes a material tray, and the material tray includes a plurality of receiving grooves arranged at intervals, and the receiving grooves are used to receive the chip 61.

[0068] Since each chip 61 is recovered from a different card, the recovered chips 61 can be received individually by the receiving slots, so as to be repackaged and used later.

[0069] In some optional embodiments, the chip 61 automatic recovery device also includes a card thickness detection unit arranged between the feeding and conveying unit 1 and the milling unit 2, a card turning unit arranged between the milling unit 2 and the separation unit 3, and a card heating unit.

[0070] Among them, the card thickness detection unit determines whether the incoming card is one card, two cards or more cards stacked together by detecting the thickness, so as to facilitate the subsequent process. That is, the thickness of the incoming card can be detected by the detection head. If the detection value is greater than the preset thickness value, an alarm operation is performed to prompt the user to process it, so as to ensure that the single card 6 to be recycled enters the subsequent process.

[0071] The card flipping unit is designed in consideration of the fact that after the milling groove is completed, the side of the card with the chip 61 faces downward, which makes it inconvenient to subsequently push the chip 61 out through the top part in the separation unit 3. Therefore, it is necessary to use the card flipping unit to flip the card 6 to be recycled upside down so that the side of the card with the chip 61 faces upward.

[0072] Considering that the chip 61 and the card body 62 are bonded with adhesive in 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 to melt the adhesive between the chip 61 and the card body 62 so that the two can be separated.

[0073] In some optional embodiments, the automatic chip 61 recovery device further includes a shearing unit disposed on a side of the second fixing portion 32 away from the second movable portion 31 , and the shearing unit is used to shear off 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 part, the wire D between the chip 61 and the card body 62 can be cut by the shearing unit, and then the suction cup can be used to adsorb and fix the chip 61.

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

[0076] First, the card 6 to be recycled is placed in the feeding and conveying unit 1 of the chip 61 automatic recycling device. Then the card is stepped and conveyed in a single piece on the conveyor belt of the equipment. The card body 62 is placed in reverse, that is, the chip 61 is facing down. It first enters the card thickness detection unit, and then enters the milling unit 2 to mill the grooves at the contacts of the chip 61 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, and the chip 61 is pushed out from the two slots milled on the back of the card (that is, the second opening K2), and the copper wire connecting the chip 61 to the card is cut off. The chip 61 is sucked onto the material tray next to it through the suction cup, and the waste cards with chip 61 are taken out and continued to be conveyed to the tail storage box for neat stacking.

[0077] See also Fig.11 The embodiment of the present invention further provides a method for automatically recycling a chip 61, comprising the following steps:

[0078] S110: putting the card 6 to be recycled into the feeding and conveying unit 1, the feeding and conveying unit 1 includes a movable conveying part;

[0079] S120: The card 6 to be recycled is delivered to the milling unit 2 through the feeding and conveying unit 1, and the first surface F1 of the card 6 to be recycled is brought into contact with the surface of the first fixing portion 22 of the milling unit 2 on the side away from the milling portion 23 through the first moving portion 21 of the milling unit 2, and the first fixing portion 22 is provided with a first opening K1, and the first opening K1 and the contact of the chip 61 of the card 6 to be recycled are arranged correspondingly, and the milling portion 23 in the milling unit 2 is extended into the first opening K1 to open a second opening K2 on the card 6 to be recycled to expose the contact of the chip 61, wherein the card 6 to be recycled includes a second surface F2 opposite to the first surface F1, and the chip 61 is arranged on the second surface F2, as shown in FIG. Figure 2 As shown;

[0080] S130: The card 6 to be recycled is sent to the separation unit 3, and the card 6 to be recycled is fixed to the second fixing portion 32 of the separation unit 3 by the second moving portion 31 of the separation unit 3, and the ejection portion 33 of the separation unit 3 is extended 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. Figure 3 to Figure 4 As shown;

[0081] S140: Pick up the separated chip 61 through the chip 61 picking unit 4, such as Figure 5 As shown;

[0082] S150: placing the chip 61 picked up by the chip 61 picking unit 4 on the chip 61 placing unit 5, as shown in FIG. Fig.10 shown.

[0083] The chip 61 automatic recovery method provided in the embodiment of the present invention is fed through the feeding and conveying unit 1, and the card 6 to be recovered is transferred to the subsequent workstation. The milling groove portion 23 is used to open a second opening K2 on the first surface F1 of the card 6 to be recovered to expose the contact of the chip 61, so as to facilitate the subsequent separation of the chip 61 and the card body 62 of the card in the separation unit 3. The separation unit 3 can use the second opening K2 through the ejection portion 33 to eject the chip 61 to achieve the separation of the chip 61 and the card body 62 of the card. The milling groove portion 23 can be in the form of a milling groove drill bit, and the chip 61 picking unit 4 is used to pick up the separated chip 61 and place the recovered chip 61 through the chip 61. The chip 61 automatic recovery device realizes the fully automatic recovery of the chip 61 in the card 6 to be recovered, which effectively improves the recovery efficiency, has a high degree of automation, replaces manual work, has high production capacity, and the processing consistency of the chip 61 automatic recovery device is good, and the quality is guaranteed.

[0084] In step S110 , the conveying portion of the feed conveying unit 1 may be in the form of a conveyor belt.

[0085] In step S120, the first movable part 21 in the milling groove unit 2 can adopt a component with power such as a cylinder, and can drive the card 6 to be recycled to move, so that the card 6 to be recycled can be pushed against the surface of the first fixed part 22 away from the milling groove part 23 through the extension of the cylinder. 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 contacts of the chip 61 are located on the side of the chip 61 body facing the first fixed part 22. Thereafter, the milling groove part 23 can be extended into the first opening K1 to open a second opening K2 on the card 6 to be recycled to expose the contacts of the chip 61.

[0086] Optionally, the milling portion 23 is used to mill grooves at designated positions on the back of the card (the welding positions of the two contacts of the chip 61 and the copper wires of the card). Preferably, two circular grooves are milled at the welding positions. The grooves are mainly located on the substrate layer of the card body 62. After milling, the two contact positions of the chip 61 can be seen through the circular grooves.

[0087] Specifically, when the first movable part 21 adopts a cylinder, the cylinder moves from bottom to top to push the card to the first fixed part 22, such as the limiting part on the cover plate for positioning. A first opening K1 is opened at the corresponding position of the cover plate and the chip 61 for the milling part 23, such as a milling cutter, to mill the groove at the corresponding position.

[0088] In step S130, the card 6 to be recycled with the second opening K2 can be fixed by the second fixing part 32, and the ejection part 33 can be extended 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 is separated from the card body 62 of the card 6 to be recycled, so as to separately recycle the chip 61. Optionally, the ejection part 33 can include a servo motor and an ejector controlled by the servo motor, and the ejector can move up and down under the drive of the servo motor to eject the chip 61.

[0089] In step S140 , after the ejection unit 33 ejects the chip 61 , the chip 61 picking unit 4 may be used to pick up and fix the chip 61 to prevent the chip 61 from falling off.

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

[0091] In some optional embodiments, between the steps of placing the card 6 to be recycled into the feed conveying unit 1 and sending the card 6 to be recycled to the milling unit 2 through the feed conveying unit 1, it also includes: sending the card 6 to be recycled into a card thickness detection unit to determine whether the card 6 to be recycled 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 adopt 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 operation is performed to prompt the user to process it to ensure that the single card 6 to be recycled enters the subsequent process.

[0093] In some optional embodiments, between the steps of sending the card 6 to be recycled to the milling unit 2 through the feeding and conveying unit 1 and sending the card 6 to be recycled to the separation unit 3, it also includes: sending the card 6 to be recycled to the card flipping unit to flip the card 6 to be recycled upside down; sending the flipped card 6 to be recycled to the card heating unit to heat and melt the glue between the chip 61 and the card body 62.

[0094] The card flipping unit is designed in consideration of the fact that after the milling groove is completed, the side of the card with the chip 61 faces downward, which makes it inconvenient to subsequently push the chip 61 out through the top part in the separation unit 3. Therefore, it is necessary to use the card flipping unit to flip the card 6 to be recycled upside down so that the side of the card with the chip 61 faces upward.

[0095] Considering that the chip 61 and the card body 62 are bonded with adhesive in 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 to melt the adhesive between the chip 61 and the card body 62 so that the two can be separated.

[0096] An embodiment of the present invention also provides a chip 61 automatic recovery and packaging device, comprising: a chip 61 automatic recovery device, which is the chip 61 automatic recovery device in any of the above embodiments; a chip 61 automatic packaging device, which is used to package the chip 61 recovered by the chip 61 automatic recovery device with a new card body 62.

[0097] It should be noted that the recovered chip 61 can be packaged and reused again through a chip 61 automatic packaging device. A single chip 61 on the chip 61 placement unit 5 can be taken out from the chip 61 placement unit 5 of the chip 61 automatic recycling device, welded to the provided new card body 62, and then packaged.

[0098] The card provided in the embodiment of the present application may be a smart card, which can be used to implement electronic transaction functions. A smart card is a type of card with a predetermined length, width, and thickness, and is also portable and convenient to use. A smart card may be a financial card, a credit card, a stored-value card, a bus card, an access card, or a membership card, but is not limited to the types of cards listed above.

[0099] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed in the present application, and these modifications or replacements should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
