Description

Technical Field

[0001] This invention relates to the field of rice cooker shell production technology, and more specifically, to a positioning mechanism and a rolling machine having the same. Background Technology

[0002] In the rice cooker shell production line, before the edge rolling process, the sheet material is bent manually and then a hydraulic press is operated to press the bent sheet material and the connecting parts to form an irregularly shaped workpiece (irregular circle). Then, it is placed manually on the positioning conveyor line for positioning, and then a robot is used to pick it up and place it into the edge rolling machine process for edge rolling.

[0003] Because the direction of the long axis of the irregularly shaped workpiece is not fixed each time it is placed manually, the robot often fails to properly place the irregularly shaped workpiece into the positioning mold of the edge rolling machine, which makes it impossible to process normally, affects the production cycle of the rice cooker shell, and reduces the processing efficiency of the rice cooker shell. Summary of the Invention

[0004] The main objective of this invention is to provide a positioning mechanism and a rolling machine having the same, so as to solve the problem of low processing efficiency of rice cooker shells in the prior art.

[0005] To achieve the above objectives, according to one aspect of the present invention, a positioning mechanism is provided, comprising: a positioning module, wherein a positioning space for positioning a target workpiece is provided within the positioning module, the size of the positioning space being adjustable; and a shaping assembly, comprising a first shaping member and a second shaping member, the first shaping member and the second shaping member being disposed opposite to each other and located above the positioning space; wherein the first shaping member and the second shaping member are movably disposed relative to each other to deform the target workpiece during the clamping process, so that the first clamping end face of the first shaping member and the second clamping end face of the second shaping member respectively fit against the outer peripheral surface of the target workpiece, and then the target workpiece is placed into the positioning space.

[0006] Furthermore, the shaping assembly also includes: a first driving component having a retractable first piston rod, the first piston rod being driven connected to the first shaping component; and a second driving component having a retractable second piston rod, the second piston rod being driven connected to the second shaping component.

[0007] Furthermore, the positioning mechanism also includes a support platform, and the positioning module and the shaping component are both mounted on the support platform. The shaping component also includes: a first bracket mounted on the support platform, extending upward from the support platform, and a first driving component mounted at the end of the first bracket away from the support platform; and a second bracket mounted on the support platform and opposite to the first bracket, extending upward from the support platform, and a second driving component mounted at the end of the second bracket away from the support platform.

[0008] Furthermore, the first support includes: a first support body, a second support body, and a third support body connected in sequence. The first support body is disposed on a support platform, and the first driving component is disposed on the third support body. The support end face of the first support body and the connection end face of the third support body are parallel to each other.

[0009] Furthermore, the first and / or second supports are Z-shaped structures.

[0010] Furthermore, the positioning mechanism also includes a clamping component having grippers to clamp the target workpiece during the movement of the first and second shaping components.

[0011] Furthermore, the positioning module also includes: a first positioning clamp; a second positioning clamp, which is positioned opposite to and spaced apart from the first positioning clamp, and the positioning space is located between the first positioning clamp and the second positioning clamp, and the first positioning clamp and the second positioning clamp are movable relative to each other.

[0012] Furthermore, the positioning module also includes a third driving component, which includes a retractable third piston rod. The third piston rod is driven to connect with the first positioning clamp or the second positioning clamp to drive the first positioning clamp or the second positioning clamp to move.

[0013] According to another aspect of the present invention, a curling machine is provided, including a positioning mechanism and a curling assembly, the curling assembly being disposed above the positioning mechanism, at least a portion of the curling assembly being movably disposed in a vertical direction to extend into the positioning mechanism to curl the edge of a target workpiece, the positioning mechanism being the aforementioned positioning mechanism.

[0014] Furthermore, the edge-rolling assembly includes: an edge-rolling rod disposed above the positioning space of the positioning mechanism; the edge-rolling rod is movably disposed in the vertical direction to extend into the positioning space and contact the target workpiece; the edge-rolling rod is rotatably disposed around a predetermined axis to roll the edge of the target workpiece.

[0015] According to the technical solution of the present invention, the positioning mechanism includes a positioning module and a shaping component. The positioning module is provided with a positioning space for positioning the target workpiece, and the size of the positioning space is adjustable. The shaping component includes a first shaping component and a second shaping component, which are arranged opposite to each other and located above the positioning space. The first shaping component and the second shaping component are relatively movable to drive the target workpiece to deform during the clamping process, so that the first clamping end face of the first shaping component and the second clamping end face of the second shaping component respectively fit against the outer peripheral surface of the target workpiece, and then the target workpiece is placed in the positioning space. Taking the edge rolling of a rice cooker shell as an example, in the previous step of the edge rolling process, the target workpiece is irregularly shaped. The first and second shaping parts are used to shape the target workpiece into the required ring shape, so that the shaped target workpiece can be adapted to the shape of the positioning space, so as to facilitate the edge rolling of the target workpiece. This avoids the problem that the target workpiece cannot fall into the positioning space for positioning due to the mismatch between the shape of the target workpiece and the positioning space, thus improving the working efficiency of edge rolling of the rice cooker shell.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] Please refer to Figures 1 to 8 The present invention provides a positioning mechanism, comprising: a positioning module 1, wherein the positioning module 1 is provided with a positioning space 10 for positioning a target workpiece 100, the size of the positioning space 10 being adjustable; and a shaping component 2, wherein the shaping component 2 includes a first shaping component 21 and a second shaping component 22, the first shaping component 21 and the second shaping component 22 being disposed opposite to each other and located above the positioning space 10; wherein the first shaping component 21 and the second shaping component 22 are movably disposed relative to each other to drive the target workpiece 100 to deform during the clamping process, so that the first clamping end face 210 of the first shaping component 21 and the second clamping end face 220 of the second shaping component 22 respectively fit against the outer peripheral surface of the target workpiece 100, and then the target workpiece 100 is placed into the positioning space 10.

[0029] The positioning mechanism provided by the present invention includes a positioning module 1 and a shaping component 2. The positioning module 1 is provided with a positioning space 10 for positioning a target workpiece 100, and the size of the positioning space 10 is adjustable. The shaping component 2 includes a first shaping member 21 and a second shaping member 22, which are arranged opposite to each other and located above the positioning space 10. The first shaping member 21 and the second shaping member 22 are relatively movable to drive the target workpiece 100 to deform during the clamping process, so that the first clamping end face 210 of the first shaping member 21 and the second clamping end face 220 of the second shaping member 22 respectively fit against the outer peripheral surface of the target workpiece 100, and then the target workpiece 100 is placed in the positioning space 10. Taking the edge rolling of a rice cooker shell as an example, in the previous step of the edge rolling process, the target workpiece 100 is irregularly shaped. The first shaping part 21 and the second shaping part 22 are used to shape the target workpiece 100 into the required ring shape, so that the shaped target workpiece 100 can be adapted to the shape of the positioning space 10, so as to roll the target workpiece 100. This avoids the problem that the target workpiece 100 cannot fall into the positioning space 10 for positioning due to the mismatch between the shape of the target workpiece 100 and the positioning space 10, thus improving the working efficiency of the edge rolling of the rice cooker shell.

[0030] Specifically, the shaping assembly 2 further includes: a first driving component 23, which has a retractable first piston rod and is drivenly connected to the first shaping component 21; and a second driving component 24, which has a retractable second piston rod and is drivenly connected to the second shaping component 22. Preferably, the first driving component 23 is a first three-axis cylinder and the second driving component 24 is a second three-axis cylinder. This arrangement facilitates the movement of the first shaping component 21 and the second shaping component 22. During the engagement of the first shaping component 21 and the second shaping component 22, a force is applied to the target workpiece 100, shaping the target workpiece 100 into the desired shape.

[0031] In practical implementation, the positioning mechanism also includes a support platform 3. The positioning module 1 and the shaping component 2 are both mounted on the support platform 3. The shaping component 2 further includes: a first bracket 25, mounted on the support platform 3, extending upwards from the support platform 3; a first driving component 23, located at the end of the first bracket 25 away from the support platform 3; and a second bracket 26, mounted on the support platform 3 and opposite to the first bracket 25, extending upwards from the support platform 3; a second driving component 24, located at the end of the second bracket 26 away from the support platform 3. Through the first bracket 25 and the second bracket 26, the first shaping component 21 and the second shaping component 22 are supported above the positioning space 10. Thus, after the first shaping component 21 and the second shaping component 22 have shaped the target workpiece 100, the target workpiece 100 falls directly into the positioning space 10 under the influence of gravity.

[0032] like Figure 5 As shown, the first support 25 includes a first support body 251, a second support body 252, and a third support body 253 connected in sequence. The first support body 251 is disposed on the support platform 3, and the first driving component 23 is disposed on the third support body 253. The supporting end face of the first support body 251 and the connecting end face of the third support body 253 are parallel to each other. This structure is simple and strong, and can support the first driving component 23 and the first shaping component 21.

[0033] Preferably, the first support 25 and / or the second support 26 have a Z-shaped structure.

[0034] In the embodiments provided by the present invention, the positioning mechanism further includes a clamping component 4, which has grippers 40 for clamping the target workpiece 100 during the movement of the first shaping component 21 and the second shaping component 22. The clamping component 4 is disposed at the end of the robot 300, and the robot 300 drives the clamping component 4 to move, thereby clamping the target workpiece from the previous station between the first shaping component 21 and the second shaping component 22.

[0035] In practical implementation, the positioning module 1 further includes: a first positioning clamping plate 11; and a second positioning clamping plate 12, which is positioned opposite to and spaced apart from the first positioning clamping plate 11. The positioning space 10 is located between the first positioning clamping plate 11 and the second positioning clamping plate 12, and the first positioning clamping plate 11 and the second positioning clamping plate 12 are movable relative to each other. This arrangement not only facilitates the adjustment of the clamping force on the target workpiece 100, but also ensures that the target workpiece 100 falls directly into the positioning space 10 without falling outside the positioning space 10.

[0036] Specifically, in order to facilitate the movement of the first positioning clamp 11 and / or the second positioning clamp 12, the positioning module 1 further includes a third driving component 13, which includes a retractable third piston rod. The third piston rod is driven to connect with the first positioning clamp 11 or the second positioning clamp 12 to drive the first positioning clamp 11 or the second positioning clamp 12 to move.

[0037] The present invention also provides a curling machine, including a positioning mechanism and a curling assembly 200. The curling assembly 200 is disposed above the positioning mechanism. At least a portion of the curling assembly 200 is movably disposed in the vertical direction to extend into the positioning mechanism to curl the target workpiece 100. The positioning mechanism is the positioning mechanism of the above embodiment.

[0038] The edge-rolling assembly 200 includes an edge-rolling rod 201, which is disposed above the positioning space 10 of the positioning mechanism. The edge-rolling rod 201 is movably disposed in the vertical direction to extend into the positioning space 10 and contact the target workpiece 100. The edge-rolling rod 201 is rotatably disposed around a predetermined axis to roll the edge of the target workpiece 100.

[0039] Furthermore, the hemming assembly 200 also includes a drive motor 202 and a hydraulic rod 203. The drive motor 202 is connected to the hemming rod 201 via a transmission belt to drive the hemming rod 201 to rotate. The hydraulic rod 203 is connected to the hemming rod 201 to drive the hemming rod 201 to move in the vertical direction.

[0040] In practical applications, the robot 300 is equipped with two clamping components at its end. The left clamping component clamps the workpiece processed by the crimping machine, while the right clamping component 4 clamps the target workpiece to the shaping position. Finally, the target workpiece is placed in the positioning space. When the robot clamps the target workpiece to the shaping position, the first and second three-axis cylinders extend to press the length range of the target workpiece within the size range of the positioning space 10. After the clamping component 4 is released, the target workpiece slides down along the inner wall of the first shaping component 21 and the second shaping component 22. The third piston rod extends for positioning. After positioning, the center of the target workpiece coincides with the orthographic projection of the axis of the rolling shaft on the horizontal plane. The vertical distance between one end of the crimping rod and the axis of the rolling shaft matches the radius of the target workpiece 100. The drive motor drives the rolling shaft and the crimping rod to rotate at high speed while the hydraulic rod 203 presses down. After forming, the crimping machine completes one working cycle.

[0041] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0042] The positioning mechanism provided by the present invention includes a positioning module 1 and a shaping component 2. The positioning module 1 is provided with a positioning space 10 for positioning a target workpiece 100, and the size of the positioning space 10 is adjustable. The shaping component 2 includes a first shaping member 21 and a second shaping member 22, which are arranged opposite to each other and located above the positioning space 10. The first shaping member 21 and the second shaping member 22 are relatively movable to drive the target workpiece 100 to deform during the clamping process, so that the first clamping end face 210 of the first shaping member 21 and the second clamping end face 220 of the second shaping member 22 respectively fit against the outer peripheral surface of the target workpiece 100, and then the target workpiece 100 is placed in the positioning space 10. Taking the edge rolling of a rice cooker shell as an example, in the previous step of the edge rolling process, the target workpiece 100 is irregularly shaped. The first shaping part 21 and the second shaping part 22 are used to shape the target workpiece 100 into the required ring shape, so that the shaped target workpiece 100 can be adapted to the shape of the positioning space 10, so as to roll the target workpiece 100. This avoids the problem that the target workpiece 100 cannot fall into the positioning space 10 for positioning due to the mismatch between the shape of the target workpiece 100 and the positioning space 10, thus improving the working efficiency of the edge rolling of the rice cooker shell.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
