[0032] like Figures 1 to 4 As shown, the shaking material device according to the embodiment of the present invention includes: a clamping mechanism 100, a shaking material mechanism 200 and a second driving mechanism 300, the clamping mechanism 100 includes a carrier 110 and a positioning assembly 120, the carrier 110 is provided with a plurality of clamping positions, and the plurality of clamping positions are respectively used to carry the workpiece 500, the positioning assembly 120 is used to cooperate with the carrier 110 to clamp or release the workpiece 500, the positioning assembly 120 includes a positioning member 122, the positioning member 122 is provided above the carrier 110, and is arranged one-to-one with the clamping position, the positioning member 122 includes a first abutting portion 1221 and a second abutting portion 1222, the first abutting portion 1221 and the second abutting portion 1222 are respectively It is used to press the two sides of the workpiece 500, and the second abutting portion 1222 is provided with a notch 1223 to avoid the special-shaped portion 520 of the workpiece 500; the shaking mechanism 200 includes a first driving mechanism 210 and a plurality of rocker arms 220, the rocker arms 220 are provided with a receiving position for receiving the portion to be broken 510 of the workpiece 500, the output end of the first driving mechanism 210 is connected to the rocker arm 220, and is used to drive the rocker arm 220 to rise and fall, so as to realize the breaking of the portion to be broken 510 of the workpiece 500; the output end of the second driving mechanism 300 is connected to the shaking mechanism 200, and is used to drive the shaking mechanism 200 to move horizontally, so that the portion to be broken 510 of the workpiece 500 can be passed through the receiving position or away from the receiving position.

[0033] It can be understood that this shaking device includes a clamping mechanism 100, a shaking mechanism 200 and a second driving mechanism 300. When in use, the workpiece 500 is clamped between the supporting platform 110 and the positioning assembly 120 of the clamping mechanism 100, and the shaking mechanism 200 is driven by the second driving mechanism 300 to approach the workpiece 500, and the part 510 of the workpiece 500 to be broken is inserted into the accommodating position of the rocker arm 220. In this way, the rocker arm 220 is raised and lowered under the drive of the first driving member, thereby shaking the workpiece 500 located at the accommodating position of the rocker arm 220 until the part 510 of the workpiece 500 to be broken is broken. 510 is broken; specifically, a notch 1223 is provided in the second abutting portion 1222 of the positioning member 122. When the first abutting portion 1221 and the second abutting portion 1222 respectively abut on both sides of the upper part of the workpiece 500, the notch 1223 can avoid the special-shaped portion 520 of the workpiece 500, thereby preventing damage to other parts of the workpiece 500 while breaking the waste; therefore, the shaking device of the present application can automatically break the waste of the workpiece 500, and can maximize the avoidance of damage to other parts of the workpiece 500, which can not only improve production capacity, but also improve product quality.

[0034] It is understood that the positioning assembly 120 includes a third driving member 121, the output end of the third driving member 121 is connected to the positioning member 122, and is used to drive the positioning member 122 to descend to clamp the workpiece 500 or to ascend to release the workpiece 500. For example, Figure 2 As shown, in this embodiment, the positioning assembly 120 also includes a third driving member 121, which is connected to the positioning member 122 and is used to drive the positioning member 122 to rise and fall, so that the positioning member 122 can cooperate with the supporting platform 110 to clamp or release the workpiece 500.

[0035] It should be understood that, in addition to the above-mentioned embodiment in which the positioning assembly 120 is configured in the form of a positioning member 122 and a third driving member 121, in some other embodiments, the positioning assembly 120 is in the form of a plurality of elastic positioning members 122. In this case, one end of the positioning member 122 itself has elasticity close to the supporting platform 110. Therefore, at this time, the third driving member 121 is not required, and only the positioning member 122 itself is required to cooperate with the supporting platform 110 to clamp or release the workpiece 500.

[0036] It is understandable that the positioning assembly 120 further includes a connecting member 123, which is connected between the output end of the third driving member 121 and the positioning member 122. Figure 2 As shown, in this embodiment, through the setting of the connecting member 123, multiple positioning members 122 can be fixed on the connecting member 123, thereby realizing the connection between the multiple positioning members 122 and the output end of the third driving member 121, and then realizing the clamping and fixation of multiple workpieces 500 at the same time.

[0037] It is understood that the clamping mechanism 100 further includes a support frame 130, and the carrier platform 110 and the positioning assembly 120 are both arranged on the support frame 130. Figure 2 As shown, in this embodiment, the clamping mechanism 100 further includes a support frame 130 , and the positioning assembly 120 and the supporting platform 110 are disposed on the support frame 130 in an upper and lower distributed manner.

[0038] It is understood that a waste box 400 is also included, which is arranged below the carrier 110 to receive the broken portion of the workpiece 500. Figures 1 to 2 As shown, in this embodiment, the shaking device also includes a waste box 400, which is correspondingly arranged below the supporting platform 110. In this way, after the shaking mechanism 200 breaks the workpiece 500 in the clamping mechanism 100, the broken part of the workpiece 500 can fall into the waste box 400, which is convenient for centralized waste discharge.

[0039] It can be understood that the rocker arm 220 includes a first vibrating portion and a second vibrating portion distributed horizontally, the first vibrating portion includes a first clamping portion 221 and a second clamping portion 222 distributed vertically, a first accommodating position is formed between the first clamping portion 221 and the second clamping portion 222 for accommodating the portion to be broken 510 on one side of the workpiece 500, and the second vibrating portion includes a third clamping portion 223 and a fourth clamping portion 224 distributed vertically, a second accommodating position is formed between the third clamping portion 223 and the fourth clamping portion 224 for accommodating the portion to be broken 510 on the other side of the workpiece 500. For example, Figures 5 and 6 As shown, in this embodiment, the rocker arm 220 includes a first vibrating part and a second vibrating part for respectively breaking the parts to be broken 510 on both sides of the workpiece 500, the first vibrating part includes a first clamping part 221 and a second clamping part 222 distributed up and down, the second vibrating part includes a third clamping part 223 and a fourth clamping part 224 distributed up and down, a first accommodating position for accommodating the part to be broken 510 on one side of the workpiece 500 is formed between the first clamping part 221 and the second clamping part 222, and a second accommodating position for accommodating the part to be broken 510 on the other side of the workpiece 500 is formed between the third clamping part 223 and the fourth clamping part 224, so that in the process of the rocker arm 220 moving up and down driven by the first driving mechanism 210, the parts to be broken 510 on both sides of the workpiece 500 can be shaken until they are broken.

[0040] It is understood that the lengths of the first clamping portion 221, the second clamping portion 222 and the fourth clamping portion 224 are the same, and the length of the third clamping portion 223 is shorter than the length of the fourth clamping portion 224, so as to avoid the irregular portion 520 of the workpiece 500. For example, Figure 6As shown, in this embodiment, the lengths of the first clamping portion 221 and the second clamping portion 222 are consistent, and the length of the third clamping portion 223 is shorter than that of the fourth clamping portion 224. Since one side of the workpiece 500 has not only a portion to be broken 510 but also a special-shaped portion 520, in order not to damage the special-shaped portion 520 while breaking the portion to be broken 510, the length of the third clamping portion 223 is shorter than that of the fourth clamping portion 224, thereby ensuring the quality of the workpiece 500.

[0041] It can be understood that the first clamping portion 221 and the third clamping portion 223 have two mutually opposing surfaces with a first inclined surface and a third inclined surface 2231, the first inclined surface gradually approaches the third clamping portion 223 from top to bottom, and the third inclined surface 2231 gradually approaches the first clamping portion 221 from top to bottom, and the second clamping portion 222 and the fourth clamping surface have two mutually opposing surfaces with a second inclined surface and a fourth inclined surface 2241, the second inclined surface gradually moves away from the fourth clamping portion 224 from top to bottom, and the fourth inclined surface 2241 gradually moves away from the second clamping portion 222 from top to bottom. For example, Figure 6 As shown, in this embodiment, the first clamping part 221 is provided with a first inclined surface on a side facing away from the third clamping part 223, the third clamping part 223 is provided with a third inclined surface 2231 on a side facing away from the first clamping part 221, and the second clamping part 222 is provided with a second inclined surface on a side facing away from the fourth clamping part 224, and the fourth clamping part 224 is provided with a fourth inclined surface 2241 on a side facing away from the second clamping part 222. Due to the setting of the first inclined surface and the second inclined surface, the first clamping part 221 and the second clamping part 222 can avoid the part to be broken 510 on one side of the workpiece 500 when shaking the part to be broken. The setting of the third inclined surface 2231 and the fourth inclined surface 2241 can also enable the third clamping part 223 and the fourth clamping part 224 to avoid the part to be broken 510 on this side when shaking the part to be broken on the other side of the workpiece 500.

[0042] It is understood that the second driving mechanism 300 includes a second driving member 310 and a mounting plate 320. The output end of the second driving member 310 is connected to the mounting plate 320 and is used to drive the mounting plate 320 to translate. The first driving mechanism 210 is fixed to the mounting plate 320. The mounting plate 320 is provided with a vertical guide rail, and the rocker arm 220 is slidably connected to the guide rail. For example, Figure 5 As shown, in this embodiment, the second driving mechanism 300 includes a second driving member 310 and a mounting plate 320 arranged at the output end of the second driving member 310, the first driving mechanism 210 is fixed to the mounting plate 320, and the rocker arm 220 is vertically slidably connected to the guide rail of the mounting plate 320. The mounting plate 320 can be translated under the drive of the second driving member 310 and drive the rocker arm 220 to translate. The rocker arm 220 can also be raised and lowered along the guide rail under the drive of the first driving mechanism 210 to realize shaking of the material.

[0043] It is understood that the rocking mechanism 200 further includes an eccentric member 230, a linkage member 240, and a slide plate 250. The eccentric member 230 is connected to the output end of the first driving mechanism 210 and can rotate under the drive of the first driving mechanism 210. The linkage member 240 is eccentrically connected to the output end of the first driving mechanism 210 through the eccentric portion. One end of the linkage member 240 is hinged to the eccentric portion, and the other end is hinged to the slide plate 250. The slide plate 250 is slidably connected to the guide rail and fixed to the plurality of rocker arms 220. For example, Figures 5 to 7 As shown, in this embodiment, the shaking mechanism 200 also includes an eccentric member 230, a linkage member 240 and a slide plate 250. The eccentric member 230 is connected to the output end of the first driving mechanism 210, one end of the linkage member 240 is eccentrically hinged to the eccentric member 230, and the other end of the linkage member 240 is hinged to the slide plate 250. The rocker arm 220 is connected to the mounting plate 320 through the slide plate 250, and the slide plate 250 is slidingly connected to the mounting plate 320. Therefore, when in use, when the first driving mechanism 210 drives the eccentric member 230 to rotate, it can drive one end of the linkage member 240 to rotate, so that the other end of the linkage member 240 can be lifted and lowered, thereby driving the slide plate 250 to lift and lower on the mounting plate 320, thereby realizing the up and down movement of the rocker arm 220.
