[0029] Next, the technical solutions in the embodiments of the present invention will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0030] Please refer to Figure 1 , an embodiment of the present invention provides a magazine reciprocating feeding mechanism, including: a bottom plate 1, a positioning fixture fixing plate 2, multiple groups of magazine positioning fixtures 3 arranged on the positioning fixture fixing plate, a loading magazine 4 arranged in the magazine positioning fixture, a transfer mechanism 5 arranged above the bottom plate, and a lifting mechanism 6 arranged below the bottom plate. In a specific embodiment, two sets of magazine positioning fixtures, transfer mechanisms, and lifting mechanisms are provided to achieve continuous reciprocating feeding.

[0031] Please refer to Figures 2 - 4 , the magazine positioning fixture 3 includes multiple groups of magazine positioning plates 31 and support columns 32 for fixing the loading magazine arranged on the positioning fixture fixing plate. The top of the support column is connected to the sensor bracket fixing plate 34 through an adjustment screw 33. A fixed bracket 35 is installed on the sensor bracket fixing plate, and multiple pairs of sensors 36 are arranged on the sensor bracket fixing plate and the fixed bracket. In a specific embodiment, four sets of loading magazines are installed on the positioning fixture fixing plate, and two pairs of sensors are symmetrically arranged on both sides of each set of loading magazines. One pair of sensors is fixed on the sensor bracket fixing plate through a sensor bracket 37, and the other pair of sensors is installed on the sensor bracket and connected and fixed to the sensor bracket fixing plate through the fixed bracket.

[0032] Specifically, the magazine positioning plate 31 includes a first magazine positioning plate 311 and a second magazine positioning plate 312 installed on the positioning fixture fixing plate through a magazine limit bottom plate 37. An anti-fooling pin 38 is arranged on the first magazine positioning plate, and the anti-fooling pin cooperates with the anti-fooling groove on the loading magazine to prevent the loading magazine from being installed reversely.

[0033] Such as Figure 5As shown, a pre-tightening mechanism 30 for pressing the charging clip is arranged in the second clip positioning plate, and the pre-tightening mechanism includes a pre-tightening block 302 and a fixing block 303 fixedly connected by a positioning pin 301. When the charging clip is loaded into the clip positioning plate, the pre-tightening block contacts the charging clip in the clip positioning plate, and two return springs 304 are arranged in the fixing block. The return springs are installed in the spring limiting holes on the pre-tightening block and the fixing block and abut against the inner side surface of the second clip positioning plate, so as to press the charging clip inward.

[0034] like Figure 6 As shown, the loading clip 4 includes a clip shell 41, a contoured cavity 42 for placing the product is arranged inside the clip shell, an anti-foolproof groove 43 cooperating with the anti-foolproof pin is arranged on the clip shell, and an upper buckle 44 and a lower buckle 45 are respectively arranged at the upper and lower ends of the clip shell, and the product is fixed by the contoured cavity. After being full, the upper and lower buckles are closed to prevent the product from falling out. An identification place 46 is arranged on the clip shell to distinguish the direction in which the product is loaded into the loading clip to prevent reverse loading.

[0035] In addition, a reflective sensor 39 is fixedly installed on the sensor bracket fixing plate. When the reflective sensor detects that the upper buckle is in the open state and the shooting sensor detects that there is material in the upper layer of the loading clip, the robot takes the material. When it detects that there is no material in the upper layer of the loading clip, the lifting mechanism pushes the product in the clip shell upward to feed the material.

[0036] See also Figure 7 The transfer mechanism 5 includes a rodless cylinder 51 arranged on the base plate and linear slides 52 symmetrically and parallelly arranged on both sides of the rodless cylinder. The linear slides are fixed to the base plate through slide pads 53. A guide rail slider 54 is arranged on the linear slide. The positioning fixture fixing plate is fixedly connected to the guide rail slider. The cylinder slider 50 on the rodless cylinder is fixedly connected to the cylinder fixing block 55. The cylinder fixing block is installed in a fixing groove below the positioning fixture fixing plate. The rodless cylinder can drive the positioning fixture fixing plate to slide along the direction of the linear slide, thereby driving the loading clip to slide back and forth in the horizontal direction of the linear slide to feed.

[0037] A first sensing sheet 56 is provided below the positioning jig fixing plate, and a limit photoelectric switch 57 and a zero position photoelectric switch 58 which cooperate with the first sensing sheet are provided on the bottom plate. The sliding stroke of the positioning jig fixing plate is limited between the photoelectric zero position and the limit by the first sensing sheet, and a photoelectric protection cover 59 is provided outside the limit photoelectric switch and the zero position photoelectric switch to play a protective role.

[0038] See also Figure 8 , 9, the lifting mechanism 6 includes a lifting fixing plate 61 fixedly connected to the bottom plate, a linear module 62, a lifting assembly 63, a synchronous belt mechanism 64, and a servo motor 65.

The lifting assembly is fixedly connected to the slider on the linear module through a module connecting plate 67. The lifting assembly 63 includes a support plate 631 and a lifting rod 632 arranged on the support plate. The support plate is fixedly connected to the module connecting plate through a reinforcing rib 633. A push block 634 is arranged at the top end of the lifting rod. When the lifting rod moves upward, it can penetrate the direct bearing 7 on the bottom plate and abut against the loading magazine on the positioning jig fixing plate, thereby realizing the lifting of the product.

[0039] Please refer to Figure 10 , the synchronous belt mechanism 64 includes a first synchronous pulley 641, a second synchronous pulley 642, and a synchronous belt 643. The output end of the servo motor penetrates the motor connecting plate and is connected to the first synchronous pulley. The lower end of the direct module penetrates the motor connecting plate and is connected to the second synchronous pulley. After the servo motor drives the first synchronous pulley to rotate, it drives the second synchronous pulley to rotate through the synchronous belt, thereby driving the linear module to work. In addition, a synchronous pulley guard can be added to play a protective role.

[0040] In addition, it further includes a module fixing plate 68. The module fixing plate is fixedly connected to the lifting fixing plate and the motor connecting plate. An optical profile 681 is arranged on the module fixing plate. A grooved optical upper limit 683 and a grooved optical lower limit 684 are installed on the optical profile. A second induction piece 682 is arranged on the slider of the linear module. The second induction piece moves with the lifting assembly on the linear module. The sliding stroke of the lifting assembly is limited within the optical upper and lower limits by the second induction piece. The optical upper and lower limits play a protective role to prevent abnormal program positioning.
