[0002] When stacked workpieces are fed separately, in order to prevent two adjacent workpieces from sticking to each other, a brush is generally provided on one side of the material frame to act on the workpieces, so that when the previous workpiece is fed, the next workpiece is separated from the previous workpiece by the brush. However, after the brush is provided, it is not convenient to load a new workpiece into the material frame in the existing feeding mechanism. Utility Model Content

[0036] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of some applications, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0037] The present application provides a feeding mechanism, which can feed stacked workpieces in sequence and prevent two adjacent workpieces from adhering to each other during feeding.

[0038] In some embodiments, the workpiece may be an atomizer sheet.

[0039] See also Figure 1 and Figure 2 The feeding mechanism includes a feeding component 100 and a dividing component 200. The feeding component 100 is used to sequentially feed the stacked workpieces 700. The dividing component 200 prevents two adjacent workpieces 700 from adhering to each other when the workpieces 700 are fed.

[0040] The loading assembly 100 may include a base 110, a material frame 120 and a transfer structure 130. The material frame 120 is disposed on the base 110, and a receiving cavity 121 with an opening is disposed on the top of the material frame 120, and the receiving cavity 121 is used to receive the stacked workpieces 700.

[0041] In addition, the stacked workpieces 700 can be loaded into the accommodating cavity 121 from the opening, and the workpieces 700 stacked in the accommodating cavity 121 can be loaded sequentially from the opening.

[0042] Specifically, the transfer structure 130 can transfer the uppermost workpiece 700 in the material frame 120 through the opening.

[0043] Furthermore, a first avoidance hole 122 is disposed on the side of the material frame 120 , and the first avoidance hole 122 is communicated with the accommodating cavity 121 .

[0044] The material dividing component 200 includes a brush 210 and a material dividing driving structure 220. The brush 210 is arranged on one side of the material frame 120. The material dividing driving structure 220 is driven and connected to the brush 210 so that the brush 210 can approach or move away from the accommodating cavity 121 through the first avoidance hole 122, and when the brush 210 approaches the accommodating cavity 121, the brush 210 can contact the edge of the workpiece 700.

[0045] Specifically, when it is necessary to load the workpiece 700 in the accommodating cavity 121, the brush 210 can be moved through the first avoidance hole 122 toward the accommodating cavity 121 under the action of the material distribution driving structure 220 until it contacts the edge of the workpiece 700 in the accommodating cavity 121. In this way, when the transfer structure 130 transfers the topmost workpiece 700 through the opening, the brush 210 adjacent to the topmost layer can be separated from the topmost workpiece 700 under the action of the brush 210, thereby avoiding the adhesion of two adjacent workpieces 700 together during the transfer of the workpiece 700 by the transfer structure 130.

[0046] When the stacked workpieces 700 need to be loaded into the accommodating cavity 121 , the material distribution driving structure 220 can drive the brush 210 to move away from the accommodating cavity 121 to avoid the brush 210 having an impact when the workpieces 700 are loaded into the accommodating cavity 121 .

[0047] It can be seen that in the present application, a brush 210 is provided on one side of the material frame 120, and the brush 210 is driven and connected to the material distribution driving structure 220. When the workpiece 700 in the receiving cavity 121 of the material frame 120 needs to be transferred through the transfer structure 130, the material distribution driving structure 220 can drive the brush 210 to move toward the receiving cavity 121 through the first avoidance hole 122 provided on the side of the material frame 120 until it contacts the edge of the workpiece 700. In this way, the workpiece 700 adjacent to the workpiece 700 being transferred can be separated from the workpiece 700 being transferred under the action of the brush 210, so as to avoid the two workpieces 700 from adhering to each other. When the workpiece 700 needs to be loaded into the receiving cavity 121 of the material frame 120, the material distribution driving structure 220 can drive the brush 210 away from the receiving cavity 121, so as to avoid the interference of the workpiece 700 with the brush 210 when the workpiece 700 is loaded into the receiving cavity 121. That is to say, the feeding mechanism of the present application can ensure that two adjacent workpieces 700 are prevented from adhering to each other when the workpieces 700 are fed, and can also prevent the workpieces 700 from interfering with the brush 210 when they are loaded into the accommodating cavity 121 of the material frame 120 .

[0048] See also Figure 3 The material distribution component 200 may also include a support seat 230, on which the brush 210 is movably disposed and can move toward or away from the accommodating cavity 121 on the support seat 230, and an elastic member 240 may also be disposed between the support seat 230 and the end of the brush 210 away from the accommodating cavity 121.

[0049] The material distribution driving structure 220 is drivingly connected to the support seat 230. The material distribution driving structure 220 drives the brush 210 to move by driving the support seat 230.

[0050] It can be understood that the elastic member 240 plays a buffering role when the brush 210 moves to contact the edge of the workpiece 700, preventing the brush 210 from rigidly contacting the workpiece 700 and causing damage to the workpiece 700. In particular, when the workpiece 700 is an atomized sheet, the atomized sheet is relatively thin, and the elastic member 240 can prevent the brush 210 from causing deformation to the workpiece 700.

[0051] Specifically, a guide rail 250 may be provided on the support base 230 , and the brush 210 is movably provided on the support base 230 via the guide rail 250 .

[0052] The support seat 230 may include a support plate 231 and a support block 232. The material distribution driving structure 220 is driven and connected to the support plate 231. The brush 210 can be set on the support plate 231 through a guide rail 250. A support block 232 is set at the end of the brush 210 away from the accommodating cavity 121. The support block 232 is set on the support plate 231. An elastic member 240 is set between the support block 232 and the brush 210, wherein the elastic member 240 can be a spring.

[0053] In addition, in some embodiments, the material distribution driving structure 220 can be a cylinder or a linear motor, etc.

[0054] Further, see Figure 3 The material distribution assembly 200 may further include a mounting seat 260 and a fixing seat 270. The mounting seat 260 is movably disposed on the support seat 230, and the fixing seat 270 is connected to the mounting seat 260 to clamp and fix the brush 210. This method can facilitate the installation and fixing of the brush 210, and also facilitate the removal of the brush 210.

[0055] Specifically, the mounting seat 260 may be disposed on the support plate 231 , the fixing seat 270 and the mounting seat 260 may be fixed by bolts, and the brush 210 is located between the fixing seat 270 and the mounting seat 260 .

[0056] In some embodiments, a limiting groove may be provided on one side of the fixing seat 270 and / or the mounting seat 260 , respectively, and the limiting groove is used to accommodate the brush 210 .

[0057] See also Figure 1 In order to improve the material separation effect between two adjacent workpieces 700, material separation components 200 can be respectively provided on both sides of the material frame 120, and the material frame 120 is provided with a first avoidance hole 122 corresponding to the brush 210 of each group of material separation components 200.

[0058] It can be understood that the brushes 210 of each group of material distribution components 200 are respectively connected by the corresponding material distribution driving structure 220, and each brush 210 can move toward or away from the accommodating cavity 121 through the corresponding first avoidance hole 122 under the action of the corresponding material distribution driving structure 220. That is, the brushes 210 on both sides of the material frame 120 can act on the edges of the workpiece 700 on both sides through the corresponding first avoidance hole 122.

[0059] See also Figure 4 In some embodiments, the material frame 120 is detachably disposed on the base 110 to facilitate loading the workpiece 700 into the accommodating cavity 121 of the material frame 120. For example, when it is necessary to load the workpiece 700 into the material frame 120, the material frame 120 can be removed from the base 110, and the material frame 120 can be placed back on the base 110 after loading the workpiece 700 into the material frame 120.

[0060] In addition, since the brush 210 of the present application is movable, when the material frame 120 is removed from the base 110 and installed into the base 110, the brush 210 can move in a direction away from the accommodating cavity 121, that is, away from the installation position of the material frame 120. In this way, the brush 210 can be prevented from interfering with the material frame 120 and the workpiece 700 in the material frame 120.

[0061] Furthermore, a first positioning portion 111 may be provided on the base 110, and a second positioning portion 123 may be provided on the material frame 120, and the material frame 120 may be detachably provided on the base 110 through the cooperation between the first positioning portion 111 and the second positioning portion 123. This method can accurately install the material frame 120 at a predetermined position of the base 110.

[0062] Specifically, in some embodiments, the first positioning portion 111 may be a positioning pin, and the second positioning portion 123 may be a positioning hole. In addition, multiple groups of the first positioning portion 111 and the second positioning portion 123 may be provided, and multiple groups of the first positioning portion 111 and the second positioning portion 123 cooperate to position the material frame 120 to improve the positioning accuracy.

[0063] See also Figure 1 and Figure 2 The feeding mechanism may further include a clamping assembly 300 , which is disposed on the base 110 , and a supporting portion is disposed on the material frame 120 . The clamping assembly 300 acts on the supporting portion to press the material frame 120 onto the base 110 .

[0064] Specifically, after the material frame 120 is positioned on the base 110 through the cooperation of the first positioning portion 111 and the second positioning portion 123, the pressing assembly 300 presses the material frame 120 on the base 110 through the abutting portion to ensure the stability of the material frame 120 when loading the workpiece 700. There can be multiple pressing assemblies 300.

[0065] In some embodiments, the abutting portion may be disposed at the bottom of the material frame 120 .

[0066] The pressing assembly 300 may adopt a rotary pressing cylinder.

[0067] See also Figure 1 and Figure 2 The feeding mechanism may further include a base 400 and a displacement assembly 500. The base 400 has a first feeding station 410 and a second feeding station 420. The displacement assembly 500 is disposed on the base 400. The displacement assembly 500 is drivingly connected to the base 110 to drive the base 110 to move back and forth between the first feeding station 410 and the second feeding station 420.

[0068] The displacement component 500 may be a linear motor, a cylinder or a screw drive device.

[0069] It can be understood that when the base 110 moves back and forth between the first loading station 410 and the second loading station 420, it can drive the material frame 120 and the clamping assembly 300 to move back and forth between the first loading station 410 and the second loading station 420. When the material frame 120 moves, the clamping assembly 300 can press the material frame 120 against the base 110 to prevent the material frame 120 from being displaced.

[0070] In addition, in some embodiments, when the material dividing assembly 200 is disposed on the base 110 , the material dividing assembly 200 may also move along with the base 110 .

[0071] See also Figure 1 In some embodiments, in order to make the structure of the feeding mechanism more compact, the body of the clamping assembly 300 can be disposed at one end of the base 110 away from the material frame 120, and the clamping end of the clamping assembly 300 can pass through the base 110 to act on the supporting portion.

[0072] Combination Figure 1 and Figure 4 The loading mechanism may further include a lifting assembly 600. The material frame 120 is provided with a second air avoidance hole (not shown in the figure). The lifting assembly 600 can act on the workpiece 700 in the accommodating cavity 121 through the second air avoidance hole to drive the workpiece 700 to rise from the accommodating cavity 121, so as to facilitate the transfer structure 130 to act on the topmost workpiece 700.

[0073] Specifically, the lifting assembly 600 can act on the lowest workpiece 700 among the stacked workpieces 700 through the second air-avoiding hole, so that the lifting assembly 600 can completely lift up the stacked workpieces 700.

[0074] For example, the second air-avoiding hole may be disposed at the bottom of the material frame 120 , and the lifting assembly 600 may lift up the stacked workpieces 700 through the second air-avoiding hole at the bottom of the material frame 120 .

[0075] Furthermore, the lifting assembly 600 can be arranged on the second loading station 420 of the base 400, and the base 110 is provided with a third air-avoiding hole 112 corresponding to the second air-avoiding hole. When the base 110 moves to the second loading station 420, the lifting assembly 600 can act on the bottom layer of the workpiece 700 in the accommodating cavity 121 through the third air-avoiding hole 112 and the second air-avoiding hole in sequence. In this way, the lifting assembly 600 does not need to move with the base 110, which can avoid occupying the installation space of the base 110, and at the same time avoid interference between the lifting assembly 600 and some structures in the loading mechanism during movement, which is beneficial to the overall layout of the loading mechanism, and can also make the structure of the entire loading mechanism more compact.

[0076] Specifically, in some embodiments, in order to prevent the lifting assembly 600 from interfering with the base 110 during movement, the lifting assembly 600 may be at least partially disposed inside the base 400. For example, the main body of the lifting assembly 600 may be disposed inside the base 400, and the lifting end of the lifting assembly 600 may extend from the air-avoiding hole of the base 400, and may sequentially pass through the third air-avoiding hole 112 and the second air-avoiding hole to act on the lowest layer of the workpiece 700 in the accommodating cavity 121.

[0077] The lifting assembly 600 may be a screw drive structure.

[0078] Of course, in other embodiments, the transfer structure 130 may also be disposed on the second loading station 420 of the base 400 to prevent the transfer structure 130 from moving with the base 110 and occupying the installation space of the base 110 .

[0079] See also Figure 1 The transfer structure 130 may include a transfer driver 132 and a suction cup 131. The transfer driver 132 may be disposed on the second loading station 420, and the transfer driver 132 is drivingly connected to the suction cup 131 to drive the suction cup 131 to suck the uppermost workpiece 700 in the accommodating cavity 121 in the material frame 120.

[0080] The transfer driving member 132 can drive the suction cup 131 to move in the vertical direction and the horizontal direction.

[0081] For example, the transfer driving member 132 can drive the suction cup 131 to move in a vertical direction to adsorb the workpiece 700 . After the suction cup 131 adsorbs the workpiece 700 , the transfer driving member 132 can drive the suction cup 131 to move in a horizontal direction to transfer the workpiece 700 .

[0082] In some embodiments, when the base 110 moves to the second loading station 420, the transfer drive 132 may be located just on one side of the base 110. In other embodiments, when the base 110 moves to the second loading station 420, the transfer drive 132 may be located just above the base 110.

[0083] In addition, the present application also provides a laser processing equipment, including a laser, a workbench and the loading mechanism in the above embodiment. The workbench is arranged on the moving path of the transfer structure 130, and is used to receive the workpiece 700 on the transfer structure 130. The laser is arranged opposite to the workbench, and the laser is used to process the workpiece 700 on the workbench.

[0084] Specifically, the transfer structure 130 transfers the workpiece 700 in the accommodating cavity 121 to the workbench, and the laser performs laser processing on the workpiece 700 on the workbench, for example, laser drilling can be performed on the workpiece 700.

[0085] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of some applications should be included in the protection scope of some applications.
