[0029] Hereinafter, the present invention will be described in detail with reference to the attached drawings.

[0031] FIG. 1 is a schematic diagram of a processing drive unit (300) and a support unit (200) according to one embodiment of the present invention, FIG. 2 is a side view of a processing device according to one embodiment of the present invention, and FIG. 3 is a front view of a processing device according to one embodiment of the present invention.

[0032] As shown in FIGS. 1 to 3, the processing device of the present invention comprises: a tool (400) for performing processing on a workpiece (20); a processing drive unit (300) coupled to the tool (400) and operating the tool (400); a support unit (200) coupled to the processing drive unit (300) and supporting the processing drive unit (300); and a pressure unit (100) coupled to the support unit (200) and applying pressure to the processing part of the workpiece (20).

[0033] Here, various plate-shaped processed materials that are subject to cutting, such as fabric formed of fibers, apex extrusions used in tires, and pads formed of rubber, can be used as the processing target (20).

[0034] Additionally, the tool (400) can perform a cutting process on the processing area. To this end, the tool (400) may be formed as a knife or a blade, and the cutting of the processing target (20) can be performed as the tool (400) performs a reciprocating motion in the longitudinal direction of the tool (400) by the operation of the processing drive unit (300).

[0035] The processing drive unit (300) can ultrasonically vibrate the tool (400), and accordingly, the movement of the tool (400) as described above is performed by ultrasonically vibrating motion, so that cutting of the processing part of the processing target (20) can be performed by high-speed operation of the tool (400).

[0036] The support member (200) can be coupled with the end (10) of the robot. The support member (200) may include a lower support member (220) coupled with the processing drive member (300); and an upper support member (210) coupled with the lower support member (220).

[0037] Here, the upper end of the upper support (210) can be connected to the end of the robot (10), and the upper support (210) can be formed with a side shape in the shape of an 'L'. Additionally, a plate-shaped lower support (220) can be formed at the bottom of the upper support (210), and accordingly, a space of a support member (200), which is a predetermined space, can be formed between the upper part of the upper support (210) and the lower support (220).

[0038] The processing drive unit (300) can be formed by penetrating the lower support body (220), thereby allowing the central part of the processing drive unit (300) and the lower support body (220) to be joined together, the upper part of the processing drive unit (300) is located in the space of the support unit (200), and a power connection part (310) to which power is connected is formed on the upper part of the processing drive unit (300), so that the operation of the processing drive unit (300) can be performed by the electricity applied to the power connection part (310).

[0040] The pressurizing unit (100) may be equipped with a pressure foot (110) that performs pressure on the processing part of the processing target (20); and a pressure actuator (120) that transmits pressure to the pressure foot (110), with one part coupled to the pressure foot (110) and the other part coupled to the support unit (200).

[0041] The pressure drive (120) can be combined with the lower support body (220) of the support member (200), and specifically, two pressure drives (120) can be formed on both sides of the support member (200) centered on the processing drive member (300). Compared to the case where one pressure drive (120) is formed to transmit pressure to the pressure foot (110), when the pressure drive (120) formed on both sides of the support member (200) is combined with the pressure foot (110), the pressure of the pressure foot (110) on the processing part of the processing target (20) can be performed more stably.

[0042] The pressure foot (110) may be equipped with a pressure support (112) whose upper end is coupled to a pressure drive (120); and a pressure body (111) which is coupled to the lower end of the pressure support (112) and applies pressure to the processing area. At this time, as shown in FIGS. 1 and 2, for the cutting process, the tool (400) and the processing drive unit (300) may be formed at an inclined position relative to the surface of the processing area, and the pressure support (112) may also be formed at an inclined position in correspondence with this.

[0043] Here, the pressure support (112) may be formed in the shape of a polygon or a circular bar with a cross-section. Additionally, the pressure body (111) may be formed in the shape of a plate, and as shown in FIG. 2, the cross-section perpendicular to the longitudinal direction of the pressure body (111) may be formed in the shape of an inverted trapezoid.

[0044] Accordingly, the processing area is pressed by the bottom surface of the pressure body (111), and at the same time, the pressure depth by the pressure body (111) can be increased due to the inverted trapezoidal cross-sectional shape, and the fixing force of the processing area by the pressure of the pressure body (111) can be increased due to the increased contact area between the surface of the processing target (20) and the pressure body (111) caused by the increased pressure depth.

[0045] Additionally, when cutting is performed by moving the tool (400) by forming an inclined surface of the pressure body (111) in the cutting direction, the movement of the pressure body (111) can be facilitated while the processing area is being pressed. To this end, the bottom surface of the pressure body (111), that is, the contact surface of the pressure body (111) with the processing area, may be provided with a curved surface.

[0046] The pressure body (111) may be provided with a guide hole (111a) which is a hole through which the end of the tool (400) passes to perform processing. The guide hole (111a) may be formed by drilling a position corresponding to the end of the tool (400) in the central part of the pressure body (111). Here, since the tool (400) is formed in an inclined position as described above, the guide hole (111a) in the pressure body (111) may also be formed by drilling in an inclined direction.

[0047] And when the pressure body (111) presses the processing area, the tool (400) passes through the guide hole (111a) and performs operation, so that the tool (400) can easily perform processing on the processing area while the pressure body (111) is easily pressing the processing area.

[0048] The pressure drive (120) described above may include an actuator, and pressure may be applied to the pressure support (112) by varying the length of the pressure drive (120) itself, or pressure may be applied to the pressure support (112) by the upper part of the pressure support (112) being combined with the pressure support and by applying pressure to the pressure support through the operation of the pressure drive (120).

[0049] The tool (400) and the pressurizing part (100) can be simultaneously applied to the processing area. As described above, a process can be performed in which the pressurizing body (111) applies pressure to the processing area while the tool (400) applies pressure to the processing area and performs cutting. Accordingly, the pressure force is increased along with the increase in the pressure area of ​​the processing area, thereby increasing the fixing force on the processing area, and thus the cutting precision of the tool (400) on the processing area can be significantly improved.

[0050] The pressure foot (110) may further be equipped with a pressure sensor (113) for measuring pressure between the pressure surface of the pressure body (111) and the surface of the processing part. The pressure sensor (113) may be formed at the bottom of the pressure body (111), and pressure force measurement by the pressure sensor (113) may be performed when the bottom surface of the pressure body (111) comes into contact with the processing part.

[0051] The tool (400) can perform a cutting process on the processing part having a flat or curved surface.

[0052] To this end, the processing device of the present invention may further include a control unit that receives pressure information from a pressure sensor (113) and transmits a control signal to a pressure actuator (120). Additionally, the control unit may store information regarding a pressure range, which is a range of pressure suitable for each type of processing target (20).

[0053] The control unit can receive the pressure value of the real-time pressure body (111) based on the pressure information above from the pressure sensor (113), and can determine whether such real-time pressure value is within the pressure range.

[0054] Here, when the control unit determines that the pressure value of the real-time pressure body (111) exceeds the maximum value of the pressure range, the control unit can reduce the pressure of the pressure body (111) by transmitting a control signal to each pressure actuator (120) to reduce the output of the pressure actuator (120).

[0055] And, when the control unit determines that the pressure value of the real-time pressure body (111) is less than the minimum value of the pressure range, the control unit can increase the pressure of the pressure body (111) by transmitting a control signal to each pressure driver (120) to increase the output of the pressure driver (120).

[0056] As described above, when using the processing device of the present invention, cutting processing is performed while providing a constant pressure to the processing area. At this time, even if the surface of the processing target (20) is formed as a curved surface, cutting processing can be performed while flexibly responding to the curved processing area by controlling the pressure at a constant level.

[0057] A processing system may be formed comprising: a processing device of the present invention; and a central processing unit that transmits information about a processing target (20) to a control unit.

[0058] As described above, the pressure range may vary depending on the type of workpiece (20), and the control unit receives the type of workpiece (20) currently being processed from the central processing unit, determines the pressure range, and then performs control of the pressure drive (120) using the determined pressure range.

[0059] In addition, when the tool (400) performs cutting by ultrasonic vibration as described above, a suitable vibration frequency range of the tool (400) may be determined according to the type of each processing target (20), and the control unit may control the output of the processing drive unit (300) so that the vibration frequency of the tool (400) is included in the corresponding vibration frequency range.

[0060] Here, output information of the processing drive unit (300) can be transmitted from the processing drive unit (300) to the control unit, and information regarding the output range, which is the range of output values ​​of the processing drive unit (300) suitable for each type of processing target (20), can be stored in the control unit.

[0061] When the control unit determines that the output value of the real-time processing drive unit (300) exceeds the maximum value of the output range, the control unit can transmit a control signal to the processing drive unit (300) to reduce the output of the processing drive unit (300).

[0062] And, if the control unit determines that the output value of the real-time processing drive unit (300) is less than the minimum value of the output range, the control unit can transmit a control signal to the processing drive unit (300) to increase the output of the processing drive unit (300).

[0063] As described above, the output range of the processing drive unit (300) may vary depending on the type of processing target (20), and the control unit receives the type of processing target (20) currently being processed from the central processing unit, determines the output range of the processing drive unit (300), and then performs control of the processing drive unit (300) using the determined output range.

[0065] The foregoing description of the present invention is for illustrative purposes only, and those skilled in the art will understand that other specific forms can be easily modified without altering the technical spirit or essential features of the present invention. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive. For example, each component described as a single unit may be implemented in a distributed manner, and components described as distributed may likewise be implemented in a combined form.
