Description

Technical Field

[0001] Embodiments of the present invention relate to a clamping mechanism, and more particularly to a clamping arm, a material frame clamping mechanism, and a multi-layer material frame depalletizer. Background Art

[0002] Clamping mechanisms, as a type of clamping device, are widely used in various mechanical fields. For example, in the process of transporting a material frame, a clamping mechanism is required to transport the material frame from point A to point B. However, the existing clamping mechanisms generally use two clamping arms arranged opposite to each other to achieve the clamping and fixing of the material frame. However, in the process of clamping and fixing the material frame, the material frame to be clamped cannot be guaranteed to be in the optimal clamping position. Therefore, when the two clamping arms are clamping the material frame, the clamping force of the two clamping arms on the material frame is often unevenly distributed, resulting in damage to the surface of the material frame during the clamping process, and at the same time, the material frame becomes unstable during the clamping process. Summary of the Invention

[0003] The purpose of the embodiments of the present invention is to provide a clamping arm, a material frame clamping mechanism and a multi-layer material frame destacker, which can achieve accurate clamping of the material frame and avoid wear on the material frame surface during the clamping process.

[0004] To solve the above technical problems, an embodiment of the present invention provides a clamping arm, comprising: a clamping arm body and two clamping components; wherein the clamping arm body has a clamping side, and the two clamping components are symmetrically arranged on the clamping side along the length direction of the clamping arm body; each of the clamping components comprises:

[0005] A limit block is provided on the clamping side; the limit block comprises: a positioning side provided away from the clamping side, and a limit side connected to the positioning side, wherein the limit side extends horizontally in a direction perpendicular to the positioning side;

[0006] The swing member is provided on the upper surface of the limit block and includes: a longitudinal swing arm and a transverse swing arm connected to the longitudinal swing arm, wherein an angle is formed between the longitudinal swing arm and the transverse swing arm, and the portion where the longitudinal swing arm and the transverse swing arm are connected is also rotatably connected to the limit block;

[0007] Two rotating bodies, one of which is disposed at the end of the longitudinal swing arm, and the other is disposed at the end of the transverse swing arm. A main control device is communicatively connected to the first drive device, the second drive device, the clamping mechanism, the feed conveyor line, and the discharge conveyor line.

[0008] In addition, an embodiment of the present invention further provides a material frame clamping mechanism, comprising two clamping arms as described above, wherein the two clamping arms are arranged opposite to each other, and at least one of the clamping arms is movable relative to the other clamping arm; the material frame clamping mechanism further comprises:

[0009] A driving device is connected to at least one of the clamping arms.

[0010] In addition, an embodiment of the present invention further provides a multi-layer material frame depalletizer, comprising: the material frame clamping mechanism described above.

[0011] Compared with the existing technology, when the clamping parts of one clamping arm and the clamping parts of another clamping arm are in the process of clamping the material frame, the two swinging parts on the same clamping arm can be forced to deflect left and right to a certain extent by relying on the abutment of the rotating bodies against the material frame, so that the limit blocks of each clamping part can reach the best clamping position for the material frame, ensuring that the limit sides and positioning sides of the two limit blocks on the same clamping arm can tightly clamp the column material frame. At the same time, with the help of the two rotating bodies on the clamping parts, rolling abutment with the material frame can be achieved in the process of the clamping parts clamping the material frame, thereby effectively avoiding damage to the surface of the material frame.

[0012] In addition, each of the rotating bodies includes: a rotatable body, and a shaft coaxially connected to the body;

[0013] The shaft of one of the rotating bodies vertically passes through the end of the longitudinal swing arm and is clamped to the end of the longitudinal swing arm via a clamping spring;

[0014] The shaft of the other rotating body vertically passes through the end of the transverse swing arm and is clamped to the end of the transverse swing arm via another clamping spring.

[0015] In addition, a notch is formed on the upper surface of the limiting block, and the notch extends from the positioning side to the limiting side, and the swinging member is rotatably disposed in the notch.

[0016] In addition, the notch is provided with a limiting protrusion connected to the limiting block, and the limiting protrusion is formed by protruding along the height direction of the notch; the swing member is arranged on the limiting protrusion.

[0017] In addition, the clamping component further comprises:

[0018] The limiting shaft is vertically arranged on the limiting block and is located at the angle between the longitudinal swing arm and the transverse swing arm.

[0019] In addition, the angle is a right angle.

[0020] In addition, each of the clamping components further comprises:

[0021] An elastic component is arranged on the clamping side and extends in a direction perpendicular to the clamping side; one end of the elastic component away from the clamping side is also connected to the longitudinal swing arm.

[0022] In addition, one end of the elastic component away from the clamping side is connected to the end of the longitudinal swing arm. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] To make the objectives, technical solutions, and advantages of the present invention more apparent, various embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will appreciate that many technical details are provided in various embodiments of the present invention to facilitate a better understanding of the present application. However, even without these technical details and the various variations and modifications based on the following embodiments, the technical solutions claimed in the claims of this application can be implemented.

[0028] A first embodiment of the present invention relates to a clamping arm, such as Figure 1 and Figure 2 As shown, it comprises: a clamping arm body 1 and two clamping parts 2. The clamping arm body 1 has a clamping side 11, and the two clamping parts 2 are symmetrically arranged on the clamping side 11 along the length direction of the clamping arm body 1.

[0029] Furthermore, in this embodiment, Figure 3 As shown, each clamping component 2 includes a stopper 21, a swinging member 22, and two rotating bodies 23. The stopper 1 is disposed on the clamping side 11 and includes a positioning side 211 facing away from the clamping side 11 and a stopper 212 connected to the positioning side 211. The stopper 212 extends horizontally in a direction perpendicular to the positioning side 211.

[0030] Secondly, in this embodiment, if Figure 3As shown, the swing member 22 is arranged on the upper surface of the limit block 21, and the swing member 22 includes: a longitudinal swing arm 221, and a transverse swing arm 222 connected to the longitudinal swing arm 221. There is an angle between the longitudinal swing arm 221 and the transverse swing arm, and the part where the longitudinal swing arm 221 and the transverse swing arm 222 are connected is also rotatably connected to the limit block 21.

[0031] Finally, in this embodiment, if Figure 3 As shown, one of the two rotating bodies 23 is disposed at the end of the longitudinal swing arm 221 , and the other rotating body 23 is disposed at the end of the transverse swing arm 222 .

[0032] From the above content, it is not difficult to see that when the clamping parts 2 on the clamping arms of this embodiment are in the process of clamping the material frame 100 with the clamping parts 2 on the other clamping arms, the two swinging parts 22 on the same clamping arm can be forced to have a certain left and right deflection by relying on the abutment of the material frame 100 by the rotating bodies 23, so that the limit blocks 21 of each clamping part 2 can reach the best clamping position for the material frame 100, ensuring that the limit sides 212 and the positioning sides 211 of the two limit blocks 21 on the same clamping arm can tightly clamp the column material frame 100. At the same time, with the help of the two rotating bodies 23 on the clamping parts 2, rolling abutment with the material frame 100 can be achieved in the process of the clamping parts 2 clamping the material frame 100, thereby effectively avoiding damage to the surface of the material frame 100.

[0033] Specifically, in this embodiment, Figure 3 As shown, each rotating body 23 includes a rotatable body 231 and a shaft 232 coaxially connected to the body 231. The shaft 232 of one rotating body 23 vertically passes through the end of the longitudinal swing arm 221 and is engaged with the end of the longitudinal swing arm 221 via a retaining spring 233. The shaft 232 of the other rotating body 23 vertically passes through the end of the transverse swing arm 222 and is engaged with the end of the transverse swing arm 222 via another retaining spring 233, thereby achieving rotational connection between the two rotating bodies 23 and the longitudinal swing arm 221 and the transverse swing arm 222, respectively.

[0034] In addition, in this embodiment, Figure 3 As shown, a notch 213 is formed on the upper surface of the limit block 21. Moreover, the notch 213 extends from the positioning side 211 to the limiting side 212, and the swing member 22 is rotatably disposed in the notch 213. At the same time, it should be noted that in this embodiment, as Figure 3As shown, the notch 213 also has a limiting protrusion 214 connected to the limiting block 21. The limiting protrusion 214 protrudes along the height direction of the notch 213. The corresponding swing member 22 is disposed on the limiting protrusion 214 and is rotatably connected to the limiting protrusion 214. It can be seen that the limiting protrusion 214 raises the swing member 22, so that during the swing member 22 rotation process, the two rotating bodies 23 can be respectively brought into the notch 213, thereby ensuring that the positioning side 211 and the limiting side 212 of the limiting block 21 can ultimately clamp and fix the material frame 100.

[0035] In addition, as a preferred solution, in order to provide a limit for the swing member 22 when it rotates left and right, to prevent the swing member 22 from rotating too much, as shown in FIG. Figure 3 As shown, in this embodiment, the clamping component 2 also includes: a limiting shaft 24, and the limiting shaft 24 is vertically arranged on the limiting block 21, and is located at the angle between the longitudinal swing arm 221 and the transverse swing arm 222 of the swing member 22. Therefore, the rotation angle of the swing member 22 during rotation can be limited by the limiting shaft 24, avoiding the swing member 22 from rotating too much and rotating too far.

[0036] In addition, it is worth mentioning that in this embodiment, Figure 3 As shown, each clamping component 2 further includes an elastic component 25 disposed on the clamping side 11, and the elastic component 25 extends in a direction perpendicular to the clamping side 11. At the same time, the end of the elastic component 25 away from the clamping side 11 is also connected to the longitudinal swing arm 221. It is not difficult to see that the elastic component 25 can always apply a certain rebound force to the longitudinal swing arm 221 of the swinging member 22, so that when the clamping component 2 clamps the material frame 100, the rotating body 23, which is rotatably connected to the longitudinal swing arm 221, can first abut the material frame 100 to achieve rough positioning of the material frame 100. Then, the positioning side 211 and the limiting side 212 of the limiting block 21 can clamp the material frame 100, thereby achieving transportation of the material frame 100. It can be seen that the elastic component 25 can further improve the accuracy and stability of the clamping of the material frame 100.

[0037] Furthermore, as a preferred solution, in the process of actual application, if Figure 3 As shown, when the elastic component 25 is set, the elastic component 25 can be set as close to the end of the longitudinal swing arm 221 as possible, so that the end of the elastic component 25 away from the clamping side can be connected to the end of the longitudinal swing arm 221, thereby further improving the rebound performance of the elastic component 25 to the longitudinal swing arm 221.

[0038] The second embodiment of the present invention relates to a material frame clamping mechanism, such as Figure 4As shown, it includes: two clamping arms as described in the first embodiment, and the two clamping arms are arranged opposite to each other, and at least one of the clamping arms can move relative to the other clamping arm.

[0039] In addition, if Figure 4 As shown, the material frame clamping mechanism of this embodiment further includes: a driving device 3, and the driving device 3 is connected to at least one of the clamping arms. Specifically, in this embodiment, the driving device 3 can be a cylinder, and the telescopic rod of the cylinder is connected to the clamping arm body 1, so as to drive the clamping arm body 1 to move relative to the other clamping arm body 1.

[0040] A third embodiment of the present invention relates to a multi-layer material frame depalletizer, which includes: the material frame clamping mechanism as described in the second embodiment.

[0041] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present invention, and that in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present invention.
