If the contents of the two images are inconsistent, the plastic sheet after the sponge is attached is determined to be unqualified. A sorting mechanism 5 is arranged between the pressing mechanism 6 and the supporting mechanism 2. When the pressing mechanism 6 acts on the sorting mechanism 5, the sorting mechanism 5 will screen out the plastic sheet with incorrect sponge pad attachment position, the plastic sheet with the correct sponge pad attachment position is the qualified plastic sheet, and the plastic sheet with incorrect sponge pad attachment position is the unqualified plastic sheet. Under the joint action of the pressing mechanism 6 and the sorting mechanism 5, the device stores the qualified plastic sheet and the unqualified plastic sheet in the inside of two containers respectively to complete the material screening work.

[0041] In order to smoothly convey the plastic sheets to the interior of the supporting mechanism 2, the structure of the conveying mechanism 1 is detailed below. The conveying mechanism 1 includes a lifting frame 11 fixedly connected to the upper surface of the processing table, the upper surface of the lifting frame 11 is fixedly connected to a linear vibrating feeder 12, and the upper end of the linear vibrating feeder 12 is fixedly connected to a guide rail 13. After the plastic sheet is placed inside the guide rail 13, the linear vibrating feeder 12 is started, and the linear vibrating feeder 12 drives the guide rail 13 to vibrate at a high frequency, and the plastic sheet is vibrated and conveyed along the inner wall of the guide rail 13 toward the direction close to the transfer mechanism 3 until the plastic sheet is vibrated and conveyed to the interior of the supporting mechanism 2.

[0042] In order to move the plastic sheet to the work station for bonding the sponge pad after the supporting mechanism 2 receives the plastic sheet, the structure of the supporting mechanism 2 is detailed as follows: the supporting mechanism 2 includes a first cylinder 21 fixedly connected to the upper surface of the processing table, one end of the piston rod of the first cylinder 21 is fixedly connected to a supporting plate 22, two storage grooves 23 are provided on the top of the supporting plate 22, one of the storage grooves 23 is connected to the inside of the guide rail 13, when the plastic sheet is vibrated and transported to the inside of one of the storage grooves 23 along the inner wall of the guide rail 13, the computer device detects that the plastic sheet is in place through the camera lens 4, and the computer device starts the first cylinder 21, so that the piston rod of the first cylinder 21 drives the supporting plate 22 to move horizontally, and transfers the plastic sheet to one side of the guide rail 13, at this time, one of the storage grooves 23 drives the plastic sheet to move to the lower side of the camera lens 4, and the position of the plastic sheet moved to the lower side of the camera lens 4 is the bonding position, and there are two bonding positions, and this state is as shown in FIG. Figure 2 As shown, at this time, the other storage groove 23 is connected to the inside of the guide rail 13, that is, when one of the storage grooves 23 is connected to the guide rail 13, the position of the other storage groove 23 is the position of the fitting position.

[0043] In order to move the sponge pad to be bonded to the bonding position and place the sponge pad at a predetermined position on the plastic sheet, the structure of the transfer mechanism 3 is detailed below. The transfer mechanism 3 includes a movable frame 31. A displacement mechanism is provided between the movable frame 31 and the processing table, which is used to drive the movable frame 31 to move horizontally along one side of the supporting mechanism 2. A first electric telescopic rod 33 is fixedly connected to the inside of the movable frame 31. A negative pressure pipe 32 is fixedly connected to the lower end of the first electric telescopic rod 33. The upper end of the negative pressure pipe 32 passes through the side wall of the movable frame 31. The upper end of the negative pressure pipe 32 is connected to an external negative pressure fan. After the lower end of the negative pressure pipe 32 contacts the upper surface of the sponge pad, the negative pressure fan The air in the negative pressure tube 32 is extracted so that the sponge pad is adsorbed on the lower end of the negative pressure tube 32, and the first electric telescopic rod 33 is contracted to drive the negative pressure tube 32 and the sponge pad to move vertically upward, and then the movable frame 31 is driven to move horizontally through the displacement mechanism, so that the negative pressure tube 32 drives the sponge pad to move to just above the bonding station, and the first electric telescopic rod 33 is extended to drive the negative pressure tube 32 and the sponge pad to move vertically downward. After the sponge pad contacts the plastic sheet at the bonding position, the negative pressure fan is turned off to release the negative pressure state in the negative pressure tube 32, and then the negative pressure tube 32 is reset by the first electric telescopic rod 33 and the displacement mechanism, and the sponge pad can be placed on the plastic sheet.

[0044] In order to fit the sponge pad onto the plastic sheet, the structure of the pressing mechanism 6 is detailed below. The pressing mechanism 6 includes a positioning plate 61 fixedly connected to the upper surface of the processing table, and a position near the top of one side of the positioning plate 61 is set as an inclined surface, and a second cylinder 62 is fixedly connected to one side of the inclined surface, and a second electric telescopic rod 63 is fixedly connected to one end of the second cylinder 62. The corresponding second cylinder 62 is started to extend its piston rod to drive the second electric telescopic rod 63 to move to the top of the bonding station where the plastic sheet is placed, so that the second electric telescopic rod 63 is extended until the lower end of the second electric telescopic rod 63 cooperates with the supporting plate 22 to clamp and fix the sponge pad and the plastic sheet, so that the sponge pad is attached to the plastic sheet.

[0045] After the sponge pad is attached to the plastic sheet, the second electric telescopic rod 63 is contracted to break away from the contact with the plastic sheet, and the piston rod of the second cylinder 62 is contracted to drive the second electric telescopic rod 63 to reset. At this time, the computer device detects whether the plastic sheet attached with the sponge is qualified through the camera lens 4. The two sides of the supporting plate 22 are symmetrically fixedly connected with the blowing pipes 24, and the two blowing pipes 24 are respectively connected to the inside of the two storage grooves 23. The two blowing pipes 24 are externally connected to the air pump. When the computer device has completed the detection, the air pump injects the airflow into the corresponding blowing pipe 24, so that the airflow is injected into the storage groove 23 where the plastic sheet is placed through the blowing pipe 24, and the plastic sheet is blown out of the storage groove 23 by the airflow.

[0046] In order to store qualified plastic sheets and unqualified plastic sheets in two containers respectively according to the results of computer equipment detection to complete the screening work, the structure of the sorting mechanism 5 is refined as follows. The sorting mechanism 5 includes a box body 51 fixedly connected to the upper surface of the lifting frame 11, and a partition 52 is fixedly connected to the inner wall of the box body 51. A side slide 53 is symmetrically fixedly connected to the side of the box body 51 away from the feeding mechanism 7. The two side slides 53 are respectively located on both sides of the partition 52. Two placement boxes are arranged on the upper surface of the processing table. The two placement boxes are respectively located below the outer ends of the two side slides 53. Two switching components 54 are arranged on the top of the box body 51, and the guide rail 13 is located between the two switching components 54. The switching component 54 includes a top groove 541 opened on the top of the box body 51, and a rotating plate 542 is rotatably connected to the inner wall of the top groove 541. A side groove 543 is opened on the side wall of the partition 52. A tension spring 544 is fixedly connected to the upper surface of the rotation plate 542. One end of the tension spring 544 away from the partition 52 is fixedly connected to the upper surface of the box body 51, and one end of the rotation plate 542 is in contact with one side of the partition 52. A qualified channel is set between the side of the partition 52 away from the rotation plate 542 and the inner wall of the box body 51, and an unqualified channel is set between the side of the partition 52 close to the rotation plate 542 and the inner wall of the box body 51. The placement box close to the qualified channel is a qualified product placement box, and the placement box close to the unqualified channel is an unqualified product placement box.

[0047] The laminating station of the plastic sheet corresponds to one of the top grooves 541, that is, the storage slot 23 where the plastic sheet laminating the sponge is placed is connected to the top groove 541. When the computer device detects that the plastic sheet laminating the sponge is qualified, the plastic sheet blown out from the storage slot 23 by the airflow successively passes through the top groove 541 and the side groove 543 into the qualified channel. The bottom surfaces of the box body 51 and the side slide 53 are both inclined surfaces, so that the plastic sheet in the qualified channel slides along the inclined surface to the inside of one of the side slides 53, and then slides along the inclined surface to the inside of the qualified product placement box. When the computer device detects that the plastic sheet laminating the sponge is not good, the plastic sheet is blown out from the storage slot 23 by the airflow and enters the qualified channel through the top groove 541 and the side groove 543. When qualified, the computer equipment starts the corresponding second cylinder 62, so that its piston rod drives the second electric telescopic rod 63 to move to the top of the rotating plate 542 close to the plastic sheet, and then extends the second electric telescopic rod 63 to press one side of the rotating plate 542 downward, and the rotating plate 542 rotates until a gap allowing the plastic sheet to pass through appears between one end of the rotating plate 542 and the inner wall of the partition 52. At this time, the plastic sheet blown out of the storage slot 23 by the airflow falls through the gap into the unqualified channel, and then slides to the inside of the unqualified product placement box, thereby realizing the separate storage of qualified plastic sheets and unqualified plastic sheets.

[0048] When the unqualified plastic sheets are blown into the unqualified channel, in order to prevent the unqualified plastic sheets from accidentally entering the qualified channel through the side groove 543, a movable groove is provided on the top of the partition 52, and a baffle 545 is slidably connected to the inner wall of the movable groove. The side wall of the baffle 545 is provided with a matching groove 546, and the matching groove 546 is communicated with the inside of the side groove 543. A vertical rack 547 is fixedly connected to the side of the baffle 545 close to the tension spring 544, and an arc-shaped rack 549 is fixedly connected to the upper surface of the rotating plate 542. A gear 548 is rotatably connected to one side of the guide rail 13, and the vertical rack 547 and the arc-shaped rack 549 are both meshed with the gear 548. The second electric telescopic rod 63 presses the rotating plate 542 When rotating, the rotating plate 542 drives the arc-shaped rack 549 to rotate, and the meshing transmission between the arc-shaped rack 549 and the gear 548 drives the gear 548 to rotate. Through the meshing transmission between the gear 548 and the vertical rack 547, the vertical rack 547 drives the baffle 545 to move vertically upward along the inner wall of the movable groove. When a gap allowing plastic sheets to pass through is formed between one end of the rotating plate 542 and the inner wall of the partition 52, the mating groove 546 on the baffle 545 is misaligned with the side groove 543, so that the baffle 545 blocks the side groove 543, thereby eliminating the possibility of unqualified plastic sheets entering the qualified channel through the side groove 543, thereby improving the accuracy of distinguishing qualified plastic sheets from unqualified plastic sheets.

[0049] In order to enable the negative pressure tube 32 which can move horizontally and vertically to automatically take the sponge pad from the feeding mechanism 7, the structure of the feeding mechanism 7 is detailed as follows: the feeding mechanism 7 includes a side frame 71 fixedly connected to the upper surface of the processing table; one side of the side frame 71 is connected to a winding roller 72, a pressing roller 76 and a driving roller 75 which rotate from top to bottom in sequence; a release paper is fixedly connected to the circumferential side wall of the winding roller 72; the pressing roller 76 and the driving roller 75 are respectively pressed and matched with the upper surface and the lower surface of the release paper; one side of the side frame 71 is fixedly connected to a flattening frame 73; one side of the side frame 71 is connected to a guide roller 74 which is rotatably connected at a position above the flattening frame 73; the release paper is slidably sleeved on the outer side of the flattening frame 73; a plurality of sponge pads are attached to the release paper in a rectangular array; the guide roller 74 is in contact with one side of the release paper; one side of the side frame 71 is fixedly connected to the horizontal frame; two camera lenses 4 are installed on one side of the horizontal frame; the computer equipment monitors the negative pressure tube 71 in real time through the camera lenses 4 The first electric telescopic rod 33 is used to drive the negative pressure tube 32 to move vertically upward, so that a sponge pad can be peeled off from the release paper, thereby realizing automatic removal of the sponge pad by the negative pressure tube 32. When the computer equipment monitors that there is no sponge pad below the horizontal moving path of the negative pressure tube 32, the driving roller 75 is started to rotate, so that the driving roller 75 cooperates with the pressing roller 76 to pull the release paper, so that the release paper is unwound from the winding roller 72 for a section, until a row of sponge pads appear below the horizontal moving path of the negative pressure tube 32, thereby realizing automatic replenishment of the removable sponge pads of the negative pressure tube 32.

[0050] Usage process:

[0051] After the plastic sheet is placed inside the guide rail 13, the plastic sheet is vibrated and transported to one of the storage grooves 23 on the support plate 22, so that the piston rod of the first cylinder 21 is extended and retracted to drive the support plate 22 to move horizontally toward the flattening frame 73, and the plastic sheet is moved to one of the laminating positions. There are two laminating stations, which correspond to the two top grooves 541 respectively. The storage groove 23 at the laminating station is connected to the inside of the top groove 541. The sponge pad is placed on the plastic sheet at the laminating station in the negative pressure pipe 32, and After the plastic sheet is evacuated, the corresponding second cylinder 62 is started, so that the piston rod of the second cylinder 62 moves the second electric telescopic rod 63 to the top of the sponge pad, so that the second electric telescopic rod 63 is extended to press the sponge pad downward, so that the sponge pad is attached to the plastic sheet, and then the second electric telescopic rod 63 is evacuated from the top of the sponge pad. The computer device detects whether the sponge pad is attached correctly through the camera lens 4 and whether the plastic sheet is qualified. Then, the plastic sheet is blown out from the inside of the storage slot 23 through the airflow. The qualified plastic sheet Before the unqualified plastic sheets are blown out of the storage slot 23, the second cylinder 62 moves the second electric telescopic rod 63 to the top of the rotating plate 542, and the second electric telescopic rod 63 is extended to drive the rotating plate 542 to flip downward, so that the unqualified plastic sheets blown out of the storage slot 23 by the air flow enter the unqualified channel in the box body 51, and then fall into the unqualified collection box, so as to realize the separate storage of qualified plastic sheets and unqualified plastic sheets. , completing the stamping and screening work of the plastic sheets. When one of the storage slots 23 is located at the bonding position, the other storage slot 23 is connected to the inside of the guide rail 13. At this time, the other plastic sheet is vibrated and transported to the inside of the other storage slot 23. After the plastic sheets located at the bonding position are sorted according to whether they are qualified or not, the supporting plate 22 is moved horizontally, and the other plastic sheet can be moved to another bonding position, and the stamping and screening work can be carried out quickly, thereby shortening the interval between stamping and screening of the two plastic sheets and improving the stamping and screening efficiency.
