[0017] Compared with the prior art, the utility model has the following beneficial effects:
[0018] 1. The utility model proposes a sloped parking plate flatness detection device, which designs a slope slideway so that the parking plate workpiece to be detected passes through the gap between the detection plate and the slope slideway in turn. Whether the flatness of the workpiece is qualified is detected based on whether it passes through the gap.

[0026] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.
[0027] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.
[0028] like Figure 1 and Figure 2 As shown, the utility model discloses a slope type parking plate flatness detection device, comprising a support frame 1, the support frame 1 having an inclined side surface and a slope slide 2 fixedly arranged on the inclined side surface. In the utility model, the support frame adopts a triangular prism support frame, the right angle surface of the triangular prism support frame is fixed horizontally, and the slope slide is fixedly arranged on the inclined surface of the triangular prism.
[0029] Furthermore, a feed port 13 is provided at the top of the ramp slide 2, and the feed port 13 is close to the end of the parking plate transmission channel 15, and a direct vibrator 16 is provided below the parking plate transmission channel. Through this arrangement, the parking plate workpieces to be detected on the parking plate transmission channel move under the action of the direct vibrator, and enter the ramp slide through the feed port in sequence, which is convenient for subsequent detection and sorting. Among them, the interval time for multiple parking plate workpieces to enter the ramp slide can be controlled by controlling the direct vibrator. The time for the parking plate workpiece to complete the detection and sorting through the above-mentioned detection device is very short, and the interval time is usually slightly longer than the detection and sorting time.
[0030] The above-mentioned ramp slide 2 is sequentially arranged with a detection mechanism and a sorting mechanism from top to bottom, wherein the detection mechanism includes a fixed frame 3 and a first gasket 5 and a second gasket 6 having the same thickness as a standard parking plate workpiece, the first gasket 5 and the second gasket 6 are symmetrically arranged on both sides of the ramp slide, and the two sides of the fixed frame 3 are respectively passed through the first gasket and the second gasket and vertically fixedly connected with the ramp slide, a detection cylinder is arranged in the fixed frame 3, and a detection plate 4 is fixedly arranged at the bottom of the detection cylinder, and the two ends of the bottom surface of the detection plate 4 are respectively in contact with the first gasket 5 and the second gasket 6, and the bottom surface of the detection plate 4 is parallel to the sliding surface of the ramp slide 2. Through the above settings, the pad and the workpiece have the same thickness. In the detection state, the detection cylinder drives the detection plate downward to fit the pad. At this time, the parking plate to be detected slides down along the ramp slide in turn. The workpiece with qualified flatness can pass through the gap between the detection plate and the ramp slide, while the workpiece with unqualified flatness (including unqualified bottom and top flatness) will be stuck in the upper part of the detection plate or between the detection plate and the ramp slide because it is greater than the gap height, thereby completing the automatic detection of flatness. It should be noted that, in fact, the thickness of the parking plate workpiece is fixed. If one side is concave, the other side must be convex. Through the above detection based on whether it can pass through the gap, the effective detection of the flatness of the parking plate workpiece can be achieved.
[0031] The above-mentioned sorting mechanism includes an NG baffle 7 arranged on the ramp slide, an NG interception cylinder is arranged at the bottom of the NG baffle 7, and a first limit rod and a second limit rod are arranged on both sides of the ramp slide 2, respectively. The first limit rod and the second limit rod are respectively located at the lower side of the first gasket 5 and the second gasket 6. The first limit rod includes a first fixed rod 8, a second fixed rod 9 and a floating rod 10. The floating rod 10 is arranged between the first fixed rod 8 and the second fixed rod 9 and is slidably connected with the first fixed rod 8 and the second fixed rod 9; the extended end of the NG interception cylinder is connected with the NG baffle and the floating rod. A qualified product collection box 14 is arranged at the bottom of the ramp slide, an NG product collection box 12 is arranged on the side of the floating rod, and a transition slide 11 is arranged between the NG product collection box and the floating rod. Further, the NG baffle is arranged obliquely along the ramp slide body, the angle between the NG baffle and the first limit rod is an acute angle, and the angle between the NG baffle and the second limit rod is an obtuse angle. Through this arrangement, it is convenient for the parking plate workpiece to slide into the transition slide for automatic sorting.
[0032] In addition, the detection mechanism further includes a first opposite-beam photoelectric sensor, which is arranged on both sides of the ramp slide 2 above the detection plate 4, and is used to detect the parking plate workpiece on the ramp slide for NG judgment. In addition, the first opposite-beam photoelectric sensor, the detection cylinder, and the NG interception cylinder are all electrically connected to the external controller. Preferably, the width of the detection plate 4 is smaller than the length of the parking plate workpiece to ensure the accuracy of the flatness detection.
[0033] Through the above arrangement, when the parking plate workpiece to be detected slides down along the ramp slide, the parking plate workpiece on the ramp slide is detected by the first opposing photoelectric sensor, and the detection signal is transmitted to the external controller. If the workpiece can pass through the gap between the detection plate and the ramp slide, the first opposing photoelectric sensor detects the passing of the parking plate workpiece only within a short time (the time can be set), at which time it is considered that the flatness of the parking plate workpiece is qualified, and the external controller controls the detection cylinder and the NG interception cylinder to not move, and the qualified workpiece slides down with the slope to the qualified product collection box 14; if the workpiece cannot pass through the gap between the detection plate and the ramp slide, the first opposing photoelectric sensor detects for a long time (the time is set according to the specific situation) and sends a signal to the external controller. There is a parking plate workpiece. At this time, it is considered that the flatness of the parking plate workpiece is unqualified. The external controller controls the detection cylinder to drive the detection plate to rise. After the parking plate workpiece passes the detection plate, the detection plate is controlled to descend to the fitting pad (the detection plate descends very quickly, the process only takes a few tenths of a second, and it will fall to the original position and fit with the gasket before the next workpiece arrives). While controlling the detection cylinder to drive the detection plate to rise, the external controller controls the NG interception cylinder to drive the NG baffle and the floating rod to rise, and the unqualified workpiece slides to the NG baffle. Since the NG baffle is an inclined baffle, after the workpiece hits the NG baffle, it will gradually tend to be parallel to the baffle as it slides, and then slides to the transition slide, and then slides down to the NG product collection box 12, completing the flatness detection and sorting of the parking plate workpiece.
[0034] Furthermore, the above-mentioned sorting mechanism also includes a second through-beam photoelectric sensor electrically connected to the external controller. The second through-beam photoelectric sensor is arranged on both sides of the ramp slide below the detection plate 4, and is also used to detect the parking plate workpiece on the ramp slide, and to alarm to prevent product stacking. In addition, the external controller is electrically connected to an alarm device (such as a voice playing speaker, a buzzer, etc.). Specifically, when the second through-beam photoelectric sensor detects the parking plate workpiece on the ramp slide for a long time, it is considered that the product is stuck or stacked at this time. The external controller controls the alarm device to sound an alarm according to the detection signal, and controls the detection cylinder, NG interception cylinder, etc. to operate again after the alarm is released, so as to avoid sorting errors in this way.
[0035] The transition slide is fixedly connected to the ramp slide at the position of the floating rod. Preferably, the fixed connection is provided with an anti-jamming detection mechanism, which includes a third photoelectric sensor arranged on both sides of the transition slide, and the third photoelectric sensor is electrically connected to the external controller. The third photoelectric sensor transmits the detection signal to the external controller. When the parking plate workpiece is detected for a long time, the external controller controls the alarm device (such as a voice playback speaker, etc.) to give an alarm to avoid jamming.
[0036] As another embodiment, a third limit rod and a fourth limit rod are respectively arranged on both sides of the above-mentioned ramp slide, and the third limit rod and the fourth limit rod are respectively located on the upper side of the first gasket and the second gasket to ensure that the parking plate workpiece slides along the ramp slide to avoid sliding out of the ramp slide.
[0037] The specific working process of the utility model is as follows:
[0038] The parking plate workpieces to be inspected on the parking plate transmission channel enter the ramp slideway in sequence through the feed port under the action of the straight vibrator, and the parking plates to be inspected slide down along the ramp slideway in sequence;
[0039] If the parking plate workpiece to be inspected can pass through the gap between the inspection plate and the ramp slideway, it is considered that the flatness of the parking plate workpiece is qualified. At this time, the first opposing photoelectric sensor detects the parking plate workpiece only for a short time, and the external controller controls the inspection cylinder and the NG interception cylinder to stop moving according to the detection signal, and the qualified workpiece slides down with the ramp to the qualified product collection box 14;
[0040] If the parking plate workpiece to be inspected cannot pass through the gap between the inspection plate and the ramp slide, it is considered that the flatness of the parking plate workpiece is unqualified. At this time, the first opposing photoelectric sensor detects the presence of a parking plate workpiece for a long time (the time is set according to the specific situation), and the external controller controls the inspection cylinder to drive the inspection plate to rise according to the detection signal. After the parking plate workpiece passes, the inspection plate is controlled to descend to the fitting pad. While controlling the inspection cylinder to drive the inspection plate to rise, the external controller controls the NG interception cylinder to drive the NG baffle and the floating rod to rise, and the unqualified workpiece slides to the NG baffle. Since the NG baffle is an inclined baffle, the workpiece will gradually tend to be parallel to the baffle after hitting the NG baffle, and then slide to the transition slide, and then slide down to the NG product collection box 12, completing the flatness detection and sorting of the parking plate workpiece.
[0041] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
