Multiple filters are orderly arranged and conveyed by the feeding mechanism 1, and the material dividing mechanism 2 is used to push the filters in sequence, and then the grabbing mechanism 3 grabs the filters to complete the mobile grabbing and load them onto the gas meter workpiece 200 of the conveying mechanism 4, so that the assembly is smoother.

[0051] like Figure 4-7 As shown, Figure 4 This is a front view of the material dispensing mechanism of the embodiment of the utility model; Figure 5 This is a structural schematic diagram of the material dispensing mechanism of an embodiment of the utility model; Figure 6 This is a diagram of the use state of the material dispensing mechanism of the embodiment of the utility model; Figure 7 This is a structural schematic diagram of a material dividing plate according to an embodiment of the utility model;

[0052] Specifically, the material dividing mechanism 2 includes a material dividing support column 20, and a material dividing top plate 21 fixed on the material dividing support column 20; a material dividing slide base 22 is installed on the material dividing top plate 21; the material dividing slide base 22 is equipped with a material dividing slide 23; a material dividing plate 24 is installed on the material dividing slide 23; and a material dividing trough 25 is formed on the material dividing plate 24 with its opening facing the feeding mechanism 1.

[0053] The material distribution slide 23 is a pneumatic slide, specifically model MXS12-75. The material distribution slide 23 includes a cylinder 23-1, on which a slide rail 23-2 is fixedly provided, on which a slider 23-3 is installed, and the slider 23-3 is slidably engaged with the slide rail 23-2; the cylinder 23-1 includes a cylinder rod 23-4; one end of the cylinder rod 23-4 is connected to the slider 23-3, and the cylinder 23-1 drives the cylinder rod 23-4 to move, thereby driving the slider 23-3 to move on the slide rail 23-2.

[0054] Guide slopes 25-1 are formed on both sides of the open end of the distribution trough 25, and the guide slopes 25-1 on both sides are in a trumpet-shaped structure; the above-mentioned scheme makes it easier to transport the filter screen 100 in the feeding mechanism 1 to the distribution trough 25, increases the contact area between the guide slope 25-1 and the filter screen 100, and makes feeding safer.

[0055] The dividing plate 24 is provided with a connecting hole 27 with a horizontal axis, and the connecting hole 27 is connected to the dividing trough 25; a lower dividing baffle 28 is fixedly provided on the side of the dividing slide base 22 close to the feeding mechanism 1, and a dividing baffle 29 is vertically fixedly provided on the outer side of the lower dividing baffle 28, and an upper dividing baffle 26 is fixed on the dividing baffle 29; the upper dividing baffle 26 is arranged parallel to the lower dividing baffle 28, and a through hole 29-1 with a horizontal axis is formed on the dividing baffle 29; the upper dividing baffle 26 is provided with a mounting hole 26-1 with a horizontal axis; the through hole 29-1 is connected with the mounting hole 26-1, and when the dividing trough 25 of the dividing plate 24 moves to the mounting hole 26-1, the connecting hole 27 is arranged corresponding to the mounting hole 26-1.

[0057] The first material distribution sensor 203 and the second material distribution sensor 204 are used to detect whether there is a filter screen 100 in the material distribution trough 25, so as to facilitate the subsequent grabbing of the grabbing mechanism 3.

[0058] like Figure 8-10 As shown, Figure 8This is a front view of the feeding mechanism of the embodiment of the utility model; Fig. 9 This is a schematic diagram of the structure of the feeding mechanism of the embodiment of the utility model; Fig.10 For the utility model embodiment Fig. 9 A partial enlarged view of the A direction.

[0059] Specifically, the feeding mechanism 1 includes a vibration plate 10 for screening and conveying the filter screen 100; a guide groove 11 connected to the vibration plate 10 for conveying the filter screen 10 screened from the vibration plate 10; and a discharge portion 12 connected to the guide groove 11 for removing the accumulated filter screen 100.

[0060] In the above configuration, the vibration plate 10 is an auxiliary feeding device that can arrange multiple filter screens 100 products in an orderly manner and transport the products. After the vibration plate 10 is connected to the power supply and turned on, the filter screen 100 is vibrated and transported by the vibration plate 10, enters the arc guide rail of the vibration plate 10, and then continues to move. As the filter screen 100 moves, it reaches the position of the guide groove 11.

[0063] In the above arrangement, the filter screen 100 is vibrated and moved on the discharge trough 120 by the direct vibration feeder 13, so as to avoid the situation where the vibration and conveying effect of the vibration plate 10 is weakened when the filter screen 100 is on the discharge trough 120, resulting in the filter screen 100 being unable to continue to move; at the same time, the direct vibration feeder 13 vibrates the discharge trough 120 to move the filter screen 100 forward. The direct vibration feeder 13 can accurately control the forward rhythm of the filter screen 100, so that the assembly rhythm is more precise.

[0066] By setting a guide groove 11 at the discharge port of the vibration disk, the filter screen 100 is used to transport the filter screen 100 screened from the vibration disk 10, so that the lower end of the filter screen 100 is located in the guide groove 11, and the upper end 101 of the filter screen 100 is placed on the top of the guide groove 11. By setting the discharge part 12 and the direct vibration feeder 13, the stacked filter screens 100 are separated, and the separated filter screens 100 fall into the vibration disk 10, so that the filter screen 100 will not block the discharge groove 120, and the passing efficiency is high and the conveying stability is high.
