[0028] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings.

[0029] See also Figure 2 and Figure 3 The paper feeder of the automobile instrument panel inspection machine is used to automatically feed paper to the inspection machine. The paper feeder of the automobile instrument panel inspection machine includes a paper stacking table 1, a paper feeding mechanism 2, and a cleaning mechanism 3.

[0030] See also Figure 3 The stacking tray 11 is used to stack the products to be tested. Figure 1 This is the product style to be fed with paper in this technical solution. Style 3 is involved in this embodiment. Styles 1 and 2 are involved in other embodiments. For products of different styles, the stacking tray can adjust the structure accordingly. The stacking tray 11 includes a base. Several upper support plates 1104 are installed on the base, and the front positioning plates 1103, side positioning plates 1105, and front stop columns 1101 are installed around the upper support plates 1104. This type of stacking tray structure can adapt to products of different styles.

[0031] Each stacking table 1 is equipped with four stacking trays 11. The stacking trays 11 are positioned using a front positioning plate 1103 and side positioning plates 1105. The front of the product is placed on the upper support plate 1104, close to the front stop 1101. The product is then centered in the upper tray 11 according to the scale on the front positioning plate 1103. Stacking stops when the product reaches the upper limit mark on the front stop 1101.

[0032] If the product needs to be replaced, just position the upper paper tray 11 with the front positioning plate 1103 and the side positioning plate 1105, place the front of the product close to the front barrier column 1101 on the upper support plate 1104, and center the product in the upper paper tray 11 according to the scale on the front positioning plate 1103. Stop stacking when it reaches the upper limit mark of the front barrier column to achieve quick product replacement.

[0033] See also Figure 4 、 Figure 5 The paper feeding mechanism 2 includes a paper feeding lift structure 22 and a paper feeding structure 220. The products on the stacking tray 11 are lifted to the bottom of the paper feeding structure 220 by the paper feeding lift structure 22. The paper feeding structure 220 includes a feeder head 23 and a power assembly 230. The power assembly 230 drives the feeder head 23 to move forward, backward, left, right, and up and down.

[0034] Combine Figure 6 The paper feeding mechanism 2 includes a paper feeding and conveying structure 21. The paper feeding and conveying structure includes an electromagnetic lock 2101 and a magnetically coupled cylinder conveying unit 2103. Specifically, in this embodiment, the base of the stacking tray 11 is placed on the pre-feeding table 27, and the electromagnetic lock 2101 is locked. The magnetically coupled cylinder conveying unit 2103 conveys the product pallet into the paper feeding mechanism. After all products have been conveyed, the magnetically coupled cylinder conveying unit 2103 conveys the stacking tray to the outside of the paper feeding mechanism (the position shown in the figure), the electromagnetic lock is released, the stacking tray is manually removed, and another stacking tray with stacked products is placed in, and the above steps are repeated.

[0035] Combine Figure 4 、 Figure 5 、 Figure 7 The paper feed lifting mechanism 22 includes a lifting motor 2201, a synchronous belt 2202, and support rods. The synchronous belt 2202 is mounted on the lifting motor 2201, and the support rods are mounted on the synchronous belt 2202. The support rods can lift the paper products in the stacking tray 11. The movement of the synchronous belt 2202 drives the support rods, thereby moving the paper products upward. The support rods include a paper support rod 2204 and a side paper support rod 2203.

[0036] Combine Figure 7 In this embodiment, the paper feeding lifting structure 22 further includes an auxiliary component 201. The auxiliary component 201 includes a mounting block 202 for fixing the support rod, a slider 203 fixedly mounted on the mounting block 202, a slide rail 204 matching the slider 203, and a connecting block 205 with one end fixed to the mounting block 202 and the other end fixed to the synchronous belt.

[0037] The paper feeding mechanism 2 also includes a paper blowing assembly mounted below the feeder head 23. This assembly includes a static-eliminating air nozzle 24, which is positioned relative to the paper products to be transported. When the products rise to a predetermined position, the air from the static-eliminating air nozzle eliminates static electricity between the products, separating them.

[0038] See also Figure 5 The paper feeding mechanism 2 further includes a light emitting sensor 25 disposed below the paper feeding lifting structure 22. The light emitting sensor 25 is used to sense the product.

[0039] Specifically, the stacking tray 11, after stacking the products, is placed on the electromagnet 2101 of the pre-feeder 21. After the two slots on the stacking tray 11 are firmly aligned with the positioning posts 2102 on the pre-feeder 21, the electromagnetic lock 2101 engages, and the feed cylinder 2103 pushes the stacking tray 11 into the paper feeder. Once the stacking tray 11 is in place, the lift motor 2201 in the paper feeder lift mechanism 22, via the connecting block on the synchronous belt 2202, drives the slider up and down along the slide rail, thereby driving the paper support rod 2204 and the side support rod 2203 of the support rod to lift the products upward. The lifting mechanism stops when the products trigger the photoelectric sensor 25. The static-eliminating air nozzle 24 then blows air on the products, separating them and eliminating static electricity. The feeder head 23 then feeds paper continuously. During this process, the photoelectric sensor 25 senses a signal, causing the lift motor 2201 to incline upward, maintaining the top of the products at the paper feeder height.

[0040] See also Figure 5 , the paper feeding mechanism 2 also includes a front-and-rear adjustment structure 28, and the feeder head 23 structure is integrally mounted on the front-and-rear adjustment structure 28. Driven by the front-and-rear adjustment structure 28, the feeder head 23 can move forward and backward. Specifically, in this embodiment, the frame of the vehicle instrument panel inspection machine paper feeder includes two side panels 281, two mounting plates 282, and a cross bar 283. A strip-shaped adjustment rail is fixed to the outer side of the side panel 281, and the extension direction of the adjustment rail is the front-and-rear movement direction of the feeder head. The mounting plate 282 is slidable along the adjustment rail, the cross bar 283 is fixed to the mounting plate 282, and the feeder head 23 is fixed to the cross bar 283. The front-and-rear adjustment structure includes an electric push rod 2301 that drives the mounting plate to move on the adjustment rail, thereby driving the feeder head as a whole to move along the strip-shaped rail.

[0041] The feeder head 23 further includes a suction nozzle 2306 , which sucks the paper product and transports it.

[0042] Please combine Figure 8 、 Figure 9The feeder head 23 includes a forward and backward movement assembly for moving the feeder head nozzle 2306 back and forth. The forward and backward movement assembly includes a first swing arm 2303, a second swing arm 2304, and a sliding assembly 2308. The first swing arm 2303 and the second swing arm 2304 are rotatably connected. The first swing arm 2303 is connected to the motor of the power assembly 230, and the motor provides power to the first swing arm 2303. The movement of the first and second swing arms 2303, 2304 drives the sliding assembly 2308 to move back and forth. The feeder head nozzle 2306 is mounted on the sliding assembly 2306.

[0043] See also Figure 8 The feeder head 23 also includes an up-and-down moving assembly. The up-and-down moving assembly includes a cylinder 2305, which is mounted on the sliding assembly of the forward and backward moving assembly. The suction nozzle 2306 of the feeder head is mounted on the output rod of the cylinder.

[0044] Please combine Figure 9 The feeder head 23 includes an air separator valve 2307. The air separator valve 2307 is equipped with a compressed air hole 2307a, a vacuum air hole 2307b, and a connection port 2307c. The compressed air hole is connected to 0.6-0.8 MPa compressed air. The vacuum air hole 2307b is connected to a vacuum pump. The connection port 2307c is connected to the suction nozzle 2306 of the feeder head 23. The air separator valve 2307 is driven by the paper feed motor.

[0045] Combine Figure 8 、 9 The specific working principle of paper suction feeding is as follows: the feeder head 23 can be adjusted forward and backward via the electric push rod 2301, and the suction nozzle 2306 can be adjusted left and right. When the suction nozzle is in the lowest position, it is connected to the vacuum pump air circuit and sucks the upper product that has been blown loose. At this time, the negative pressure in the suction nozzle forms a self-balancing state. The spring inside the suction nozzle returns the piston and the suction nozzle to their original position, thus achieving independent left and right adjustment to accommodate products of different widths.

[0046] The paper feeding motor 2302 drives the first rocker arm 2303 and the second rocker arm 2304 to move the suction nozzle 2306 back and forth. At the same time, the paper feeding motor 2302 drives the air separator valve 2307 to rotate, realizing the conversion of high-pressure and negative-pressure airflow. When the suction nozzle 2306 swings to the rearmost side, the paper feeding motor 2302 is triggered to stop running. At this time, the air separator valve 2307 is in a negative-pressure ventilation state, and the suction nozzle 2306 inhales air. The cylinder 2305 extends, and the inside of the suction nozzle 2306 quickly reaches negative pressure self-balance, sucking the product up, and the cylinder 2305 retracts. Through the two contraction actions of the cylinder 2305 and the suction nozzle 2306, the product adsorbed on the top is completely separated from the next one. At this time, the paper feeding motor 2302 continues to operate, driving the suction nozzle 2306 to move forward, feeding the product into the pressure roller 31 on the paper cleaning mechanism 3. At this time, the air separation valve 2307 is in the compressed air ventilation suction nozzle 2306, blowing air to separate the product from the suction nozzle 2306 and send the product away. The above actions are repeated.

[0047] The cleaning mechanism 3 receives the product continuously fed by the feeder head and cleans it. The front end of the cleaning machine is provided with a cleaning pressure roller 31 to clean the paper product coming out of the paper feeding mechanism 2.

[0048] The present invention has at least the following beneficial effects: Products on the stacking tray are lifted to the bottom of the paper feeding structure by the paper feeding lifting mechanism. The power assembly drives the feeder head to move forward, backward, left, right, and up and down. The cleaning mechanism collects and cleans the products continuously fed by the feeder head. From the stacking tray to the paper feeding lifting mechanism and then to the paper feeding structure, paper feeding is automated and continuous, eliminating manual labor and improving efficiency.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
