Description

Technical Field

[0001] The present application relates to the field of clamping technology, and in particular to a limiting device and processing equipment. Background Art

[0002] In the processing of thin sheet materials, the thin sheet needs to be limited and fixed. In the related art, the limiting device usually uses vacuum adsorption and a pressure head to limit and fix the thin sheet. In order to facilitate the processing of the thin sheet, the pressure head usually presses and holds the waste part at the edge of the thin sheet. After the waste part is cut off, the thin sheet loses the pressing effect of the pressure head, resulting in the problem that the thin sheet is easy to deform and inconvenient for subsequent processing. Utility Model Content

[0003] In view of this, the present application provides a limiting device and a processing device, aiming to reduce the risk of thin-sheet deformation and subsequent processing defects, thereby improving the processing yield of the thin-sheet.

The base includes a bearing wall, the bearing wall is provided with a limiting area and an adsorption portion, the limiting area is used to carry materials, and the adsorption portion is provided in the limiting area and is used to adsorb materials. The first holding member is located above the bearing wall, the driving member is installed on the base, the driving member is connected to the first holding member, the driving member can drive the first holding member to rise and fall to hold or detach the material on the bearing wall, and the lifting direction of the first holding member is perpendicular to the bearing wall. The second holding member is located above the bearing wall. The transmission mechanism connects the driving member and the second holding member, and the transmission mechanism drives the second holding member to rotate and rise and fall under the drive of the driving member to hold or detach the material on the bearing wall, the lifting direction of the second holding member is perpendicular to the bearing wall, and the direction of the rotation axis of the second holding member is perpendicular to the bearing wall.

[0006] In some embodiments, the second pressing member has a first position and a second position. When the second pressing member is in the first position, the projection of the second pressing member in a direction perpendicular to the bearing wall overlaps with the limiting region; when the second pressing member is in the second position, the projection of the second pressing member in a direction perpendicular to the bearing wall is separated from the limiting region. The transmission mechanism is used to drive the second pressing member to rotate and descend to the first position to press the material in the limiting region, and the transmission mechanism is used to drive the second pressing member to rotate and rise to the second position to be out of contact with the material.

Such an arrangement enables the second pressing member to avoid the mechanism for processing the material, which is beneficial to the processing of the material and the removal of the waste material, and also enables the second pressing member to press the position of the material close to the central area, thereby facilitating the improvement of the processing yield of the material.

[0068] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

When a component is considered to be "located on" another component, it may be directly located on the other component or there may be a central component at the same time.

[0070] Unless otherwise specified, the term "plurality" as used herein means two or more than two.

[0071] The terms "first", "second", etc. are only used to distinguish different objects and shall not be understood as indicating or implying relative importance or implying the quantity, specific order or primary and secondary relationship of the indicated technical features.

[0072] The term "perpendicular" is used to describe an ideal state between two components. In actual production or use, the two components may be in a state that is approximately perpendicular to each other.

[0073] It should be recognized that the dimensions of the structures shown in the drawings are provided for better understanding and more convenient description, and the present application is not limited to the dimensions shown in the drawings. In order to make the present application clear, elements not related to the description are omitted from the details of the present specification.

[0074] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0075] In the related art, when processing materials, a limiting device is usually used to limit the thin sheet by combining vacuum adsorption and a pressure head, and then the material on the limiting device is processed. In order to facilitate the processing of the thin sheet, the pressure head is usually pressed on the waste part of the edge of the thin sheet. After the waste part is cut off, the thin sheet loses the pressure holding effect of the pressure head. The cutting fluid remaining on the bearing wall may cause the sealing ring to harden after contacting with the sealing ring. Since the material is a thin sheet structure, there is a risk of deformation of the thin sheet material after the pressure holding effect of the pressure head is lost, and after the material pressure holding effect is lost, it is not convenient for subsequent processing.

[0076] The present application discloses a limiting device, which includes a base, a first holding member, a driving member, a second holding member and a transmission mechanism. The base includes a bearing wall, and the bearing wall is provided with a limiting area and an adsorption portion. The limiting area is used to carry materials, and the adsorption portion is provided in the limiting area and is used to adsorb materials. The first holding member is located above the bearing wall, and the driving member is installed on the base. The driving member is connected to the first holding member, and the driving member can drive the first holding member to rise and fall to hold or detach the material on the bearing wall. The lifting direction of the first holding member is perpendicular to the bearing wall. The second holding member is located above the bearing wall. The transmission mechanism connects the driving member and the second holding member. The transmission mechanism drives the second holding member to rotate and rise and fall under the drive of the driving member to hold or detach the material on the bearing wall. The lifting direction of the second holding member is perpendicular to the bearing wall, and the direction of the rotation axis of the second holding member is perpendicular to the bearing wall.

[0077] The second holding member can hold the material after it is partially cut off, so that the waste part of the material is still subjected to the holding force after being cut off, thereby reducing the risk of deformation of the material after processing and subsequent processing defects, thereby improving the material processing yield.

[0078] Some embodiments of the present application will be described below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0079] See also Figure 1 and Figure 2 The embodiment of the present application provides a limiting device 100, which is used to limit the material 200. The material 200 is processed to form a thin sheet structure after being limited. The limiting device 100 includes a base 10, a first holding member 20, and a driving member 30. The base 10 is used to place the material 200, and the driving member 30 is installed on the base 10. The driving member 30 is connected to the first holding member 20 to drive the first holding member 20 to hold the material 200 on the base 10, or drive the first holding member 20 to separate from the material 200 on the base 10 to release the holding effect on the material 200.

[0080] In some embodiments, see Figure 2The base 10 includes a bearing wall 111 , and the bearing wall 111 is used for placing the material 200 .

[0081] In some embodiments, see Figure 2 The base 10 includes a first plate body 11, a second plate body 12 and a supporting column 13, which is located between the first plate body 11 and the second plate body 12 and is used to connect the first plate body 11 and the second plate body 12. The first plate body 11 is provided with a bearing wall 111, and the second plate body 12 is used to be placed on the ground or other bearing structures such as a desktop to support the base 10.

[0082] In some embodiments, see Figure 2 and Figure 3 The carrying wall 111 is provided with a limiting area 1111 and an adsorption portion 112 . The limiting area 1111 is used to carry the material 200 . The adsorption portion 112 is provided in the limiting area 1111 and is used to adsorb the material 200 .

[0083] It can be understood that the limiting area 1111 is an area for carrying the material 200. When the material 200 is placed in the limiting area 1111, the projection of the material 200 overlaps with the projection of the limiting area 1111 along the direction perpendicular to the carrying wall 111.

[0084] In some embodiments, see Figure 2 and Figure 3 The adsorption portion 112 may be a vacuum hole, and the adsorption portion 112 is connected to an air-driven structure such as a vacuum machine, so that a negative pressure is formed between the limiting area 1111 and the material 200 , thereby playing a role in limiting the material 200 .

[0085] In some other embodiments, the adsorption portion 112 may also be a magnetic structure, and the material 200 is a material that can be magnetically attracted, so that the adsorption portion 112 can adsorb and restrict the movement of the material 200 .

[0086] In some embodiments, the adsorption portion 112 is a vacuum hole, the limiting device 100 further includes a sealing ring 70 , the limiting area 1111 is provided with an annular groove 1112 , the sealing ring 70 is disposed in the annular groove 1112 , and the sealing ring 70 is used to abut against the material 200 .

[0087] The material 200 is adsorbed by the adsorption portion 112 and pressed by the first pressing member 20, squeezing the sealing ring 70, causing the sealing ring 70 to deform, which is conducive to forming a sealing area between the material 200 and the limiting area 1111, thereby facilitating the formation of negative pressure during vacuum adsorption by the adsorption portion 112, thereby enhancing the adsorption effect of the adsorption portion 112 on the material 200, and further enhancing the effect of limiting the movement of the material 200.

[0088] In some embodiments, see Figure 2 and Figure 3 The first pressing member 20 is located above the bearing wall 111, and the driving member 30 is installed on the base 10. The driving member 30 can drive the first pressing member 20 to descend to press the material 200 on the bearing wall 111. The driving member 30 can also drive the first pressing member 20 to rise to separate the first pressing member 20 from the material 200, thereby releasing the pressing effect of the first pressing member 20 on the material 200. The lifting direction of the first pressing member 20 is perpendicular to the bearing wall 111.

[0089] In some embodiments, the number of the first pressing member 20 can be one or more, and the number of the driving members can be one or more, which is not specifically limited here. One driving member 30 can drive one first pressing member 20 to rise and fall, one driving member 30 can drive multiple first pressing members 20 to rise and fall, or multiple driving members 30 can drive one first pressing member 20 to rise and fall.

[0090] In some embodiments, the driving member 30 may be a telescopic cylinder or an electric push rod, which is not specifically limited herein.

[0091] In some embodiments, see Figure 2 and Figure 3 The limiting device 100 further includes a second pressing member 40 and a transmission mechanism 50. The second pressing member 40 is located above the bearing wall 111. The transmission mechanism 50 connects the driving member 30 and the second pressing member 40. The transmission mechanism 50 drives the second pressing member 40 to rotate and rise and fall under the drive of the driving member 30. The transmission mechanism 50 drives the second pressing member 40 to rotate and fall to press the material 200 on the bearing wall 111. The transmission mechanism 50 drives the second pressing member 40 to rotate and rise to separate from the material 200 on the bearing wall 111. The lifting direction of the second pressing member 40 is perpendicular to the bearing wall 111, and the direction of the rotation axis of the second pressing member 40 is perpendicular to the bearing wall 111.

[0092] When the limiting device 100 limits the material 200, the material 200 is placed in the limiting area 1111, the adsorption part 112 adsorbs the material 200, and the first pressing member 20 presses the waste part 210 of the material 200. After the waste part 210 of the material 200 is cut, the first pressing member 20 loses the pressing effect on the material 200. At this time, the driving member 30 can drive the transmission component, so that the transmission component drives the second pressing member 40 to rotate and descend, so that the second pressing member 40 can press the material 200 after the material 200 is partially cut off, so that the waste part 210 of the material 200 is still subject to the pressing force after being cut off, reducing the risk of deformation of the material 200 after processing and subsequent processing failure, thereby improving the processing yield of the material 200.

[0093] In some embodiments, see Figures 1 to 3The second pressing member 40 has a first position 40a and a second position 40b. When the second pressing member 40 is located at the first position 40a, the projection of the second pressing member 40 in the direction perpendicular to the bearing wall 111 overlaps with the limiting area 1111. At this time, the projection of the second pressing member 40 in the direction perpendicular to the bearing wall 111 overlaps with the material 200 on the limiting area 1111. When the second pressing member 40 is located at the second position 40b, the projection of the second pressing member 40 in the direction perpendicular to the bearing wall 111 separates from the limiting area 1111. At this time, the projection of the second pressing member 40 in the direction perpendicular to the bearing wall 111 separates from the material 200. The transmission mechanism 50 is used to drive the second pressing member 40 to rotate and descend to the first position 40a to press the material 200 in the limiting area 1111. The transmission mechanism 50 is used to drive the second pressing member 40 to rotate and rise to the second position 40b to break contact with the material 200.

[0094] Considering the convenience of processing the material 200, the first holding member 20 is usually held on the waste part 210 of the material 200. When processing the part close to the central area of ​​the material 200 (non-waste part 210), the part close to the central area of ​​the material 200 is subjected to a larger cutting force. If the part close to the central area of ​​the material 200 is held at this time, it is beneficial to improve the processing yield of the material 200. In the above embodiment, the second holding member 40 is configured to be able to move between the first position 40a and the second position 40b driven by the transmission assembly. When the first holding member 20 holds the material 200, the second holding member 40 can be rotated and raised. When the first holding member 20 no longer holds the material 200, the second holding member 40 can be rotated and lowered to hold the material 200. Such a configuration enables the second pressing member 40 to avoid the mechanism used to process the material 200 , which is beneficial to the processing of the material 200 and the removal of waste. It also enables the second pressing member 40 to press the position of the material 200 close to the center area, thereby facilitating the improvement of the processing yield of the material 200 .

[0095] In some embodiments, the driving member 30 is used to drive the first holding member 20 to rise. When the first holding member 20 rises, the driving mechanism 50 is driven, so that the driving mechanism 50 drives the second holding member 40 to rotate and descend. When the first holding member 20 descends, the driving mechanism 50 is driven, and the driving mechanism 50 drives the second holding member 40 to rotate and rise. Such a configuration enables the first holding member 20 and the second holding member 40 to alternately hold, so that when the material 200 has a waste part 210, the first holding member 20 holds the material 200, and the second holding member 40 avoids the mechanism used for processing; after the waste of the material 200 is cut off, the first holding member 20 cancels the holding action, and allows the second holding member 40 to hold, thereby improving the rationality and efficiency of the operation of the limiting device 100.

[0096] In some embodiments, see Figure 4 The transmission mechanism 50 includes a first connecting assembly 51, a first steering assembly 52 and a second steering assembly 53. The first connecting assembly 51 is connected to the first pressing member 20, and the first connecting assembly 51 is driven to be lifted or lowered when the first pressing member 20 is lifted or lowered. The first steering assembly 52 is movably connected to the first connecting assembly 51, and the first connecting assembly 51 is driven to rotate when the first connecting assembly 51 is lifted or lowered, and the rotation axis direction of the first steering assembly 52 is perpendicular to the bearing wall 111. The second steering assembly 53 is movably connected to the first steering assembly 52, and the second steering assembly 53 is driven to rotate and lift or lower when the first steering assembly 52 rotates.

[0097] When the first connecting component 51 is raised or lowered, it drives the first steering component 52 to rotate. The first steering component 52 drives the second steering component 53 to rotate and raise or lower. The second steering component 53 drives the second pressing member 40 to rotate and raise or lower. The transmission mechanism 50 converts the reciprocating motion of raising or lowering into a rotational and lifting motion, which is beneficial to realize the conversion of the second pressing component between the first position 40a and the second position 40b.

[0098] In some embodiments, see Figure 4 The first steering assembly 52 includes a first rotating drum 521, and the first rotating drum 521 is provided with a first guide groove 5211. The first connecting assembly 51 includes a first rod 511 and a second rod 512, the first rod 511 connects the first holding member 20 and the second rod 512, a portion of the second rod 512 is located in the first rotating drum 521, and the second rod 512 also extends into the first guide groove 5211. The first holding member 20 drives the second rod 512 to rise and fall through the first rod 511, and the second rod 512 cooperates with the first guide groove 5211 to drive the first rotating drum 521 to rotate, and the rotation axis direction of the first rotating drum 521 is perpendicular to the bearing wall 111. The cooperation between the second rod 512 and the first guide groove 5211 converts the reciprocating motion of the first connecting assembly 51 into the rotation motion of the first rotating drum 521.

[0099] In some embodiments, the first guide groove 5211 extends along a spiral line, and the central axis of the first guide groove 5211 coincides with the central axis of the first rotating drum 521 , which helps the first connecting assembly 51 drive the first rotating drum 521 to rotate when being lifted or lowered.

[0100] In some embodiments, see Figure 4The first steering assembly 52 further includes a screw 522, which is connected to the first rotating cylinder 521, and the rotation axis of the screw 522 coincides with the rotation axis of the first rotating cylinder 521. The second steering assembly 53 includes a nut 531 and a connecting rod 532, the nut 531 is threadedly matched with the screw 522, and the connecting rod 532 connects the nut 531 and the second pressing member 40. The transmission mechanism 50 further includes a second rotating cylinder 54, which accommodates the first steering assembly 52, and is provided with a second guide groove 5411, and the connecting rod 532 is inserted into the second guide groove 5411. When the screw 522 rotates, it drives the nut 531, the connecting rod 532 and the second pressing member 40 to rotate and rise and fall.
