The embodiment of the application provides a frame waste separating module, which can be used for separating a product area 110 formed by a workpiece 100 at a production station of a die cutting process from a frame area, and then further processing the product area 110 of the workpiece 100 to obtain a membrane electrode of a fuel cell, wherein the workpiece 100 is a sheet-shaped structural member as shown in fig. 1. As shown in fig. 2, the frame waste separation module provided by the present application includes a transfer device 200 for a membrane electrode and a lower plate 300. The transfer device 200 is used for transferring the product region 110 of the workpiece 100 and the frame waste region 120 to the lower plate 300 together so as to separate the frame waste region 120 from the product region 110.

As shown in fig. 3, the transfer device 200 provided by the present application includes a main body 210, a first air tap 220 and a separating mechanism 230 are installed on the main body 210, and a second air tap 240 is disposed in the separating mechanism 230, wherein the first air tap 220 is used for contacting with and adsorbing a product area 110 in a workpiece 100, and the second air tap 240 is used for contacting with and adsorbing a frame waste area 120 in the workpiece 100, so as to transfer the workpiece 100 to a position of a lower plate 300 integrally. A separation mechanism 230 is installed at each of opposite ends of the body 210 to adsorb the rim waste region 120 from both ends of the rim waste region 120. It should be understood by those skilled in the art that the product area 110 and the frame waste area 120 may be adsorbed on the first air nozzle 220 and the second air nozzle 240 under the action of negative pressure, and when the transfer device 200 provided by the present application is used, an air pipe and a device for exhausting air may be connected to an end of the air nozzle facing away from the workpiece 100, so as to form negative pressure at the mouth of the first air nozzle 220 and the second air nozzle 240, thereby adsorbing the workpiece 100. It should be understood by those skilled in the art that in implementing the adsorption of the product area 110 and the frame waste area 120 at the same time, it is preferable that the mouths of the first air tap 220 and the second air tap 240 are at the same height, and there is no limitation on whether the movable portion 232 is at the same height as the body 210.

As shown in fig. 4 and 5, the separating mechanism 230 provided by the present application includes a fixed portion 231 and a movable portion 232 connected to the fixed portion 231. The fixed portion 231 is fixedly connected to the main body 210, and the movable portion 232 and the fixed portion 231 can move relatively. The second air tap 240 is disposed on the movable portion 232. Under the condition that the first air nozzle 220 adsorbs the product region 110 of the workpiece 100 and the second air nozzle 240 adsorbs the frame waste region 120 of the workpiece 100, the frame waste region 120 and the product region 110 can be moved relatively only by the relative movement between the movable portion 232 and the fixed portion 231, so as to separate the frame waste region 120 and the product region 110. Preferably, the direction in which the movable portion 232 moves relative to the fixed portion 231 is perpendicular to the plane in which the product region 110 is placed, that is, when the movable portion 232 moves relative to the fixed portion 231, the product region 110 and the bezel waste region 120 in the workpiece 100 move relatively in the direction perpendicular to the surface of the workpiece 100 (i.e., the surface of the product region 110), so that the product region 110 and the bezel waste region 120 can be separated better. Of course, the moving direction of the movable portion 232 relative to the fixed portion 231 may be along the length or width direction of the workpiece 100, so long as the movable portion 232 moves relatively to the fixed portion 231, the frame waste region 120 adsorbed by the second air nozzle 240 on the movable portion 232 can be separated from the product region 110 adsorbed by the first air nozzle 220.

As shown in fig. 6, the lower plate 300 provided by the present application has a protrusion 310 provided corresponding to the movable portion 232 in the separation mechanism 230. The top surface of the protrusion 310 is a second working surface 311 for contacting with the frame waste region 120 absorbed by the movable portion 232, and the lower plate 300 further has a first working surface 320 in a region between the two protrusions 310, where the first working surface 320 is used for carrying the product region 110 separated from the frame waste region 120. The second working surface 311 is higher than the first working surface 320.

That is, after the transfer device 200 provided by the present application moves above the lower plate 300, it can move downward until the frame waste region 120 absorbed by the movable portion 232 contacts the second working surface 311, and the product region 110 is located above the first working surface 320. In view of the foregoing, only the movable portion 232 and the fixed portion 231 need to perform the relative movement to enable the frame waste region 120 and the product region 110 to perform the relative movement, thereby separating the frame waste region 120 and the product region 110. Therefore, when the frame waste region 120 absorbed by the movable portion 232 contacts the second working surface 311, the body 210 in the transferring device 200 can be further moved downward, and the downward movement of the movable portion 232 is limited by the protrusion 310, so that the body 210 and the movable portion 232 move relatively, and accordingly, the frame waste region 120 and the product region 110 can be separated due to the relative movement between the fixed portion 231 and the movable portion 232 on the body 210. It should be noted that, the downward movement of the movable portion 232 is limited by the protrusion 310, and it is not possible to move the movable portion 232 downward, in some embodiments, if the second working surface 311 is a surface disposed obliquely with respect to the horizontal plane, and a component in the horizontal direction exists in the movement direction of the movable portion 232 with respect to the fixed portion 231, it may also be achieved that after the movable portion 232 presses the frame waste region 120 against the second working surface 311, the frame waste region 120 is separated from the product region 110 by the relative movement of the movable portion 232 and the fixed portion 231. A preferred embodiment of the present application is that the second working surface 311 is a horizontal surface, and the direction of relative movement between the movable portion 232 and the fixed portion 231 is a direction perpendicular to the plane in which the product area 110 is placed, i.e., a vertical direction.

According to the working principle of the frame waste separating module provided by the present application, when the transferring device 200 is used, the main body 210 of the present application is selectively connected to a driving member such as a mechanical arm, so that when the movable portion 232 is located above the protrusion 310, the mechanical arm drives the main body 210 to mechanically move downward to separate the frame waste region 120 from the product region 110.

The frame separation module provided by the application has the function of separating the frame waste region 120 from the product region 110 through the transfer device 200 and the lower plate 300, and the separated product region 110 can be placed on the first working surface 320 for processing in other working procedures, and a person skilled in the art can design the first working surface 320 according to actual needs.

Because the transfer device 200 provided by the application has the fixed part 231 and the movable part 232 which can move relatively, the relative movement between the frame waste region 120 and the product region 110 can be realized only by the relative movement between the movable part 232 and the fixed part 231, and the separation of the frame waste region 120 and the product region 110 is realized. Therefore, the transfer device 200 provided by the present application can also separately separate the frame waste region 120 from the product region 110, for example, when the frame waste region 120 and the product region 110 provided by the present application are used, the movable portion 232 is connected with a driving member, and after the first air nozzle 220 adsorbs the product region 110 and the second air nozzle 240 adsorbs the frame waste region 120, the movable portion 232 is driven by the driving member to move relative to the fixed portion 231, so that the frame waste region 120 can be separated from the product region 110. Those skilled in the art can select the driving member coupled to the movable portion 232 and install the driving member in a proper position according to actual needs.

In some embodiments of the transfer device 200 provided by the present application, the movable portion 232 includes a guide post 2321, the fixed portion 231 has a guide hole 2311, and the guide post 2321 moves along the axial direction of the guide hole 2311. It will be appreciated that the engagement of the guide posts 2321 with the guide holes 2311 serves to guide the movement of the movable portion 232. Accordingly, in some embodiments, the axial direction of the guide hole 2311 is perpendicular to the surface of the sucked workpiece 100, and it should be understood by those skilled in the art that the workpiece 100 for producing the membrane electrode is horizontally placed at the station for forming the frame waste region 120 and the product region 110, and the axial direction of the guide hole 2311 is perpendicular to the surface of the sucked workpiece 100, that is, the axial direction of the guide hole 2311 is a vertical direction, and the moving direction of the movable portion 232 with respect to the fixed portion 231 is a vertical direction.

Further, in some embodiments of the present application, the movable portion 232 and the fixed portion 231 are elastically connected, so that the movable portion 232 can automatically return to the initial position before the relative movement occurs after the movable portion 232 and the fixed portion 231 are relatively moved to separate the frame waste region 120 from the product region 110. In a specific embodiment, the guide post 2321 is sleeved with an elastic member, one end of the elastic member contacts the movable portion 232, and the other end contacts the fixed portion 231. When the movable portion 232 and the fixed portion 231 do not have relative movement, that is, the adsorbed product region 110 and the frame waste region 120 are not separated, the elastic member is in a natural length or compressed state, and after the movable portion 232 and the fixed portion 231 have relative movement, the elastic member is further compressed, so that the movable portion 232 can return to the above-mentioned initial position under the action of the elastic member. Specifically, the elastic member may be a spring or a structural member made of a material having elasticity such as rubber.

In some embodiments of the present application, the movable portion 232 includes a pressing bar 2322 for pressing the product area 110 onto the second working surface 311, the pressing bar 2322 has a first surface for contacting the frame waste area 120, two ends of the pressing bar 2322 are connected with mounting blocks 2323, and the mounting blocks 2323 are used for mounting the second air nozzle 240, that is, the second air nozzle 240 adsorbs the second air nozzle 240 from two ends of the frame waste area 120, so that better adsorption can be performed on the frame waste area 120, and sagging of the edge of the frame waste area 120 under gravity can be reduced. The middle parts of the frame waste material areas 120 positioned on the two second air nozzles 240 are pressed on the second working surface 311 by the pressing bars 2322, so that the pressing effect on the frame waste material areas 120 is better.

The shape of the mounting block 2323 is not limited, as long as the mounting block 2323 does not contact the second working surface 311 first in the process of relatively moving the movable part 232 and the fixed part 231, so that the pressing bar 2322 cannot press the frame waste region 120 on the second working surface 311. For example, as shown in fig. 4 and 5, the mounting block 2323 is L-shaped, one end of the mounting block 2323 is connected with one end of the molding 2322, the other end protrudes out of the molding 2322 toward the direction of the molding 2322 away from the first surface, and the second air nozzle 240 is located at the end of the mounting block 2323 protruding out of the molding 2322. In this embodiment, a space capable of avoiding the fixed portion 231 is formed between the two connection blocks, so that interference occurring when the movable portion 232 and the fixed portion 231 relatively move is effectively avoided, and further, the distance of the relative movement between the movable portion 232 and the fixed portion 231 is increased.

In some embodiments of the transfer device 200 provided by the present application, a sensor for detecting the workpiece 100 is further disposed on the body 210, and a through hole 211 is formed at a position of the body 210 where the sensor is disposed, so that the sensor detects through the through hole 211 to determine whether the workpiece 100 is adsorbed on the transfer device 200 provided by the present application. Preferably, the sensor is used to detect the product region 110 of the workpiece 100.

In the frame waste separating module provided by the application, the lower plate 300 is further provided with a positioning piece 400, and the upper end of the positioning piece 400 protrudes out of the first working surface 320. The positioning member 400 is provided with a guiding surface for contacting with an edge of the hole structure in the product area 110 for positioning the product area 110, i.e. positioning of the product area 110 on the first working surface 320 can be achieved by providing the positioning member 400 for further processing of the product area 110 on the first working surface 320 and for facilitating transfer of the product area 110 from the first working surface 320. Those skilled in the art can set the machining process performed by the product area 110 on the first working surface 320 according to actual needs.

Further, the guide surface of the positioning member 400 is not limited, as long as the guide surface can guide the product region 110, and the guide surface may be a conical surface, a slanted plane, or the like.

To reduce damage to the workpiece 100, in some embodiments, foam is disposed on both the first work surface 320 and the second work surface 311.

The using method of the frame waste separation module provided by the application comprises the following steps:

S1: moving the transfer device 200 to the upper part of the production station, and then adsorbing the product area 110 through the first air tap 220 and adsorbing the frame waste area 120 through the second air tap 240;

S2: transferring the rim waste region 120 with the product region 110 to above the lower plate 300 (i.e., the position shown in fig. 2);

s3: the transfer device 200 is driven to move downward until the frame waste region of the edge work piece 100 contacts the second working surface 311 (i.e., the state shown in fig. 7);

S4: the body 210 in the transfer device 200 is driven to move downwards continuously, so that the frame waste region 120 is pressed on the second working surface 311 under the action of the movable part 232, and the product region 110 moves downwards along with the body 210 continuously, so that the frame waste region 120 is separated from the product region 110 (i.e. the state shown in fig. 8);

S5: eliminating the adsorption of the first air nozzle 220 to the product area 110, so that the product area 110 falls to the first working surface 320 under the action of gravity, and automatically adjusts the position under the action of the positioning piece 400 (i.e. as shown in fig. 9);

S6: the transfer device 200 is driven to move upward and transfer the adsorbed rim waste region 120 to the waste frame.

The above is only one use method of the frame waste separating device provided by the application, and one skilled in the art can adopt other use methods according to actual needs.

The above description is only of the preferred embodiments of the present application and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art.
