[0032] The present invention will be further described in detail below with reference to specific embodiments. The following embodiments are only descriptive and not limiting, and should not be used to limit the protection scope of the present invention.

[0033] Unless otherwise specified, the raw materials used in this invention are all commercially available products. Unless otherwise specified, the methods used in this invention are conventional methods in the field. The quantities of all substances used in this invention are conventional usage quantities. Structures and connections not described in detail in this invention can be understood as conventional technical means in the field.

[0034] A device for tearing off QR codes on electronic products, the device being detachably connected to the electronic product (not shown) to which the QR code needs to be removed, such as... Figures 1 to 6 As shown, the device includes a pressing mechanism 1, a baffle bracket 2, a conveyor belt 3, support legs 4, a platform 5, a discharge port 6, a rotating tearing mechanism 7, and a workpiece mounting mechanism 8. The platform is arranged horizontally, and the support legs are vertically mounted on the platform at intervals along the circumference. Two conveyor belts are arranged horizontally, with even intervals between them, and both are connected to a motor (not shown in the figure). The motor can drive the conveyor belts to move back and forth horizontally. The conveyor belts are connected to the support legs, which provide support for the conveyor belts. The baffle bracket is arranged horizontally, and the lower longitudinal sides of the baffle bracket are mounted on the longitudinal outer sides of the conveyor belt, providing shielding protection for the workpieces when the device is working. The workpiece mounting mechanism is detachably connected to the conveyor belt, and the conveyor belt, driven by the motor, can also drive the workpiece mounting mechanism to move back and forth horizontally.

[0035] The pressing mechanism is arranged vertically, with its upper part connected to the upper part of the baffle bracket and its lower part extending downwards and above the workpiece mounting mechanism. The workpiece mounting mechanism is detachably connected to the conveyor belt below the pressing mechanism, and can detachably place the electronic product workpiece to be peeled off on it. The bottom of the pressing mechanism is detachably connected to the workpiece mounting mechanism, and can press down on the electronic product workpiece to be peeled off on the workpiece mounting mechanism for subsequent operations. The rotating peeling mechanism is arranged horizontally on a platform and below the pressing mechanism and the workpiece mounting mechanism. The rotating peeling mechanism can peel off and rotate the QR code on the electronic product workpiece to be peeled off, which is placed on the workpiece mounting mechanism and pressed down by the pressing mechanism. The discharge port is located on the platform below the rotating peeling mechanism. The rotating peeling mechanism can rotate the QR code to be peeled off from the electronic product workpiece to be peeled off to the top of the discharge port and release the QR code. The QR code can fall into the discharge port and be discharged through the discharge port.

[0036] In use, the qualified electronic product workpiece to be peeled off is placed on the workpiece mounting mechanism. The conveyor belt moves the workpiece mounting mechanism and the workpiece to be peeled off together to the pressing mechanism. At this point, the conveyor belt stops, and the pressing mechanism starts to press the workpiece firmly onto the workpiece mounting mechanism. Then, the peeling mechanism starts to peel off the QR code on the workpiece. The peeling mechanism then rotates to rotate the peeled QR code to the top of the discharge port and releases it. The QR code falls into the discharge port and is discharged. The peeling mechanism then rotates back along the same path. Finally, the conveyor belt starts again to move the workpiece mounting platform back to its initial position, completing the operation. Subsequent operations can be performed in this manner.

[0037] This device incorporates a pressing mechanism and a rotating code-tearing mechanism, ensuring the stability and accuracy of the code-tearing process while reducing operational difficulty and error rates. The device's structural design allows for detachable connection between the workpiece mounting mechanism and the workpiece to be code-teared, facilitating replacement and maintenance. This device improves work efficiency, reduces operator workload, and offers high accuracy, greatly simplifying production.

[0038] In this embodiment, as Figure 7 , Figure 8As shown, the workpiece mounting mechanism includes a workpiece clamp 8-1, a workpiece mounting mechanism body 8-2, and a QR code mounting groove 8-3. The workpiece mounting mechanism body is arranged horizontally. Multiple workpiece clamps are arranged in an array with intervals on the upper surface of the workpiece mounting mechanism body. The workpiece clamps can hold the electronic product workpiece to be peeled off. Multiple QR code mounting grooves are arranged in an array with intervals on the lower surface of the workpiece mounting mechanism body. The QR code mounting grooves are arranged vertically and vertically corresponding to the electronic product workpiece to be peeled off. The QR code to be peeled off (not shown in the figure) corresponding to the electronic product workpiece to be peeled off is detachably pasted in the QR code mounting groove. The electronic product workpiece to be peeled off is positioned directly above the corresponding QR code to be peeled off.

[0039] The workpiece mounting mechanism of this device can mount electronic product workpieces to be peeled off and their corresponding QR codes. The workpiece fixture can mount and set the electronic product workpieces to be peeled off, and the QR code mounting groove can mount and set the QR code corresponding to the workpiece. This mechanism can mount multiple workpieces and their matching QR codes at one time, improving the efficiency of peeling off codes and increasing production efficiency.

[0040] Better, such as Figure 11 and Figure 12 As shown, the workpiece fixture includes a front workpiece pressing plate 8-4, a middle workpiece pressing plate 8-5, a rear workpiece pressing plate 8-6, and a workpiece support plate 8-7. The workpiece support plate is arranged horizontally and can detachably hold the electronic product workpiece to be peeled off. The front workpiece pressing plate is connected to and arranged on one horizontal side of the workpiece support plate, and can detachably press down on the front part of the front horizontal side of the electronic product workpiece to be peeled off placed on the workpiece support plate. The middle workpiece pressing plate is connected to and arranged on one longitudinal side of the middle of the workpiece support plate, and can detachably press down on the middle horizontal side of the electronic product workpiece to be peeled off placed on the workpiece support plate. The rear workpiece pressing plate is connected to and arranged on the other horizontal side of the workpiece support plate, and is also connected to the middle workpiece pressing plate, and can detachably press down on the rear horizontal side of the electronic product workpiece to be peeled off placed on the workpiece support plate. The workpiece fixture of this device has a simple structure, is easy to manufacture and use, and brings great convenience to users.

[0041] In this embodiment, as Figure 9 and Figure 10As shown, the rotary code-tearing mechanism includes a rotary platform 7-1, a rotary pneumatic cylinder 7-2, a rotary plate 7-3, a code-tearing platform 7-4, a lifting pneumatic cylinder 7-5, a lifting guide rod 7-6, an air valve 7-7, a lifting support plate 7-8, and an air port 7-9. The lifting support plate is arranged horizontally, and the lifting pneumatic cylinder is arranged longitudinally. The lifting pneumatic cylinder is coaxially arranged with the lifting support plate. The output end of the lifting pneumatic cylinder is arranged vertically upward and connected to the lifting support plate. The output end of the lifting pneumatic cylinder can drive the lifting support plate to move up and down vertically. Under the action of the lifting pneumatic cylinder, the air port on the lifting support plate can be tightly and detachably connected to the QR code mounting slot of the workpiece mounting mechanism, thereby enabling the code-tearing operation, which is convenient and quick.

[0042] The tear-off code platform is horizontally positioned. The lower part of the lifting pneumatic cylinder is connected to the platform. The platform is connected to a lifting support plate via lifting guide rods. Multiple lifting guide rods are vertically positioned and spaced out circumferentially. The lower part of each guide rod is slidably connected to the platform. Driven by the pneumatic cylinder, the guide rods can move vertically up and down on the platform. The upper part of each guide rod is fixedly connected to the lifting support plate. The support plate, driven by the pneumatic cylinder and the lifting guide rods, can move vertically upwards or downwards, allowing it to move closer to or further away from the pressing mechanism and workpiece mounting mechanism, facilitating subsequent operations. The lifting guide rods serve both guiding and supporting functions.

[0043] A rotating platform is connected to each of the two outer sides of the tear-off code platform. The rotating platforms are fixedly mounted on the platform. The rotating platforms are arranged vertically and two are spaced apart horizontally. One side of the tear-off code platform is connected to one of the rotating platforms through a rotating shaft 7-10. The rotating shaft facilitates the longitudinal rotation of the tear-off code platform around the rotating platform. The other side of the tear-off code platform is connected to another rotating platform through a rotating plate and a rotary pneumatic cylinder. The rotary pneumatic cylinder is arranged longitudinally. The working surface of the rotary pneumatic cylinder on one side is connected to the tear-off code platform through the rotating plate. The rotary pneumatic cylinder can drive the rotating plate and the tear-off code platform to rotate back and forth around the rotating platform in the longitudinal circumferential direction, which facilitates the rotation of the adsorbed QR code to the top of the discharge port and then the release operation. It is convenient and quick to use.

[0044] The air valves and air ports are all installed on the lifting support plate and are spaced out. The air ports are positioned directly above the discharge port, aligning vertically with the QR code mounting slots. The air ports are positioned directly below the QR code mounting slots on the workpiece mounting mechanism. The air valves can be connected to a vacuum pump (not shown in the figure). The air valves and air ports are tightly connected via connecting pipes (not shown in the figure). The air ports can be detachably and tightly connected to the QR code to be removed, which is pasted inside the QR code mounting slot of the workpiece mounting mechanism. When the air port is in close contact with the QR code to be removed, the vacuum pump... The air pump can create a vacuum in the air inlet through the air valve. Under this vacuum, the QR code installed in the QR code mounting slot of the workpiece mounting mechanism is firmly held in place by the air inlet. Then, the lifting pneumatic cylinder moves downward, causing the air inlet to move downward, which in turn moves the QR code downward and tears it off. The code remains firmly attached to the air inlet and will not fall off, preventing it from flying around and polluting the environment. The subsequent rotating pneumatic cylinder can rotate and retrieve the code. The air inlet and vacuum pump further ensure the accuracy and continuity of the code tearing operation and improve production efficiency.

[0045] The rotary pneumatic cylinder can drive the rotating plate, the code-tearing platform, the lifting pneumatic cylinder, the lifting guide rod, the air valve, the lifting support plate, and the air port to rotate inward and outward along the longitudinal circumference. Since the air port is located directly above the discharge port, it can rotate the torn QR code to directly above the discharge port. Therefore, after the rotary pneumatic cylinder rotates 90 degrees and the vacuum pump stops drawing vacuum, the QR code adsorbed on the air port can be released and fall into the discharge port to complete the discharge.

[0046] The rotary code-tearing mechanism can peel off the QR codes on electronic products mounted on the workpiece mounting table using an air vent. Then, by rotating the mechanism, the detached code is positioned above the discharge port, and the vacuum pump stops, causing the QR code to detach and be removed from the device. The air vent design reduces the mechanical code-tearing structure, ensuring the safety of the equipment during the code-tearing process. The integrated design of rotation and code-tearing reduces the space required for the equipment and improves production efficiency.

[0047] In this embodiment, as Figure 9 and Figure 10As shown, the pressing mechanism includes a pressing pneumatic cylinder 1-1, a pressing platform 1-2, a pressing balance bar 1-3, a pressing support plate 1-4, a first positioning post 1-5, and a second positioning post 1-6. The pressing platform and pressing support plate are both horizontally positioned. The pressing pneumatic cylinder is vertically positioned and coaxially connected to the pressing platform. The working direction of the pneumatic cylinder is downward, and the bottom of its output end is coaxially connected to the pressing support plate. Multiple pressing balance bars are evenly distributed at intervals along the circumference. The pressing balance bars are vertically positioned, and their upper parts are slidably connected to the pressing platform via a sliding sleeve 1-7. The bottom of the pressing balance bars is connected to the pressing support plate. Under the drive of the pressing pneumatic cylinder, the pressing support plate can move along the pressing balance bar and sliding sleeve... The mechanism moves vertically up and down. Multiple first and second positioning posts are arranged vertically and spaced apart. They are vertically positioned on the lower surface of the pressing support plate and directly above the workpiece mounting mechanism. The first positioning post is vertically matched with the workpiece mounting mechanism body, and can be detachably engaged with it to securely press and hold the workpiece mounting mechanism body, ensuring stability and facilitating subsequent operations. Similarly, the second positioning post is vertically matched with the workpiece clamp of the workpiece mounting mechanism, and can be detachably engaged with it to securely press and hold the workpiece clamp, ensuring stability and facilitating subsequent operations.

[0048] The device's pneumatic cylinder pushes the pressing balance plate to move up and down, the pressing balance rod provides balance support for the balance plate, and the pressing platform provides support for the pneumatic cylinder, sliding sleeve, and pressing balance rod. The first and second positioning posts ensure that the pressing mechanism is accurately matched with the workpiece mounting platform. The pressing mechanism can hold the workpiece mounting mechanism in place to prevent misalignment and protect the stability of the device's operation. The first and second positioning posts ensure that the device can accurately and efficiently tear off the QR codes on electronic products, improving production efficiency.

[0049] In this embodiment, the device for tearing the QR code on the electronic product also includes a position detector 9, which is connected to the pressing mechanism. The position detector can detect whether the workpiece mounting mechanism exceeds its working area and will issue a fault alarm when it moves beyond its range.

[0050] Although embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will understand that various substitutions, variations, and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments.
