Description

Technical Field

[0001] This application relates to the field of PVC sheath processing technology, and in particular to an automatic inspection device for sheath length dimensions. Background Technology

[0002] Generally speaking, PVC sheaths are dip-molded. After dip molding, the products need to be cut and processed. After processing, a comprehensive appearance inspection and dimensional inspection (sampling inspection) are required. Due to strict customer requirements, the dimensions need to be fully confirmed. However, manual dimensional inspection of the sheaths cannot be fully matched one by one, and manual inspection is inefficient. Utility Model Content

[0003] In order to more comprehensively check the length of PVC sheaths and improve the efficiency of length checking of PVC sheaths, this application provides an automatic length checking device for sheaths.

[0004] The automatic sheath length inspection device provided in this application adopts the following technical solution: An automatic inspection device for the length of a sheath includes a vibrating feeding tray, a conveyor belt, an image detection module, and a defective product sorting module. The feed end of the conveyor belt is connected to the discharge port of the vibrating feeding tray. The image detection module is mounted above the conveyor belt. A good product collection box is provided at the end of the conveyor belt away from the vibrating feeding tray. The defective product sorting module is located between the image detection module and the good product collection box, and is used to sort defective products that do not meet the length and size requirements.

[0005] By adopting the above technical solution, in the actual inspection process, the vibrating feeder and conveyor belt work together to automatically drive the PVC sheaths at a uniform speed through the image detection module. When the PVC sheaths pass through the image detection module, the module automatically collects image data of the PVC sheaths. The image data processor then automatically calculates the length of the PVC sheaths based on the image data and determines whether the length is within acceptable limits. If the length is within acceptable limits, the defective product sorting module remains inactive, and the PVC sheaths continue to be conveyed to the good product collection box by the conveyor belt. If the length is outside acceptable limits, the defective product sorting module activates and sorts the defective products off the conveyor belt. Through the coordinated use of the vibrating feeder, conveyor belt, image detection module, and defective product sorting module, the technical effect of automatically and comprehensively detecting the length of PVC sheaths can be achieved, which is more efficient than manual inspection.

[0006] Preferably, the image detection module includes a camera and a light source mounted directly above the conveyor belt. The data output terminal of the camera is connected to the image data processor, the data output terminal of the image data processor is connected to the controller, and the signal output terminal of the controller is connected to the defective product sorting module.

[0007] By adopting the above technical solution, a clear and bright field of view can be provided for the camera through the light source, so that the camera can capture clear image data of the PVC sheath.

[0008] Preferably, the defective product sorting module includes a defective product rejection air gun and a defective product channel. The entrance end of the defective product channel is fixedly connected to a frame on the side of the conveyor belt. The defective product rejection air gun is fixedly installed on the frame on the side of the conveyor belt, and the defective product rejection air gun is opposite to the entrance end of the defective product channel.

[0009] By adopting the above technical solution, when the length dimension of the PVC sheath fails the inspection and the PVC sheath is judged to be a defective product, the defective product rejection air gun blows air to send the defective PVC sheath to the defective product channel and sends it out, which can achieve the technical effect of automatic sorting of defective products.

[0010] Preferably, the defective product channel is inclined from top to bottom.

[0011] By adopting the above technical solution, the inclined setting of the defective product channel can facilitate the smooth delivery of PVC sheaths.

[0012] Preferably, the frame on the left and right sides of the conveyor belt is equipped with a first limiting channel and a second limiting channel with adjustable width, the defective product channel is located between the first limiting channel and the second limiting channel, and both the first limiting channel and the second limiting channel are mounted above the conveyor belt. The first limiting channel is located between the defective product channel and the vibrating feeding tray, and the second limiting channel is located between the defective product channel and the good product collection box.

[0013] By adopting the above technical solution, the PVC sheath can be arranged in an approximately linear array on the conveyor belt and pass under the camera in sequence through the first limiting channel and the second limiting channel.

[0014] Preferably, the first limiting channel includes a first stop bar and a second stop bar arranged opposite to each other, and the second limiting channel includes a third stop bar and a fourth stop bar arranged opposite to each other. A plurality of connecting plates are fixedly connected to the outer sides of the first stop bar, the second stop bar, the third stop bar and the fourth stop bar. An adjustment waist hole is opened through each of the plurality of connecting plates, and the direction of the adjustment waist hole is arranged along the width direction of the conveyor belt. Several mounting screw holes are provided on the frame on both sides of the conveyor belt. Positioning bolts are threaded into the screw holes, and the connecting plate is pressed between the bolt and the frame.

[0015] By adopting the above technical solution, the connecting plate can be fixed by mounting bolts. Since the connecting plate is provided with adjustment holes, the distance between the first and second stops, and between the third and fourth stops can be adjusted according to the width of the PVC sheath to be inspected, so as to meet the inspection requirements of PVC sheaths of different specifications and improve the availability of the automatic inspection device.

[0016] In summary, the automatic sheath length inspection device of this application has at least the following beneficial technical effects: 1. By combining and using the vibrating feeding tray, conveyor belt, image detection module and defective product sorting module, the technical effect of automatic and comprehensive detection of the length and size of PVC sheaths can be achieved, which is more efficient than manual inspection. 2. The connecting plate can be fixed by mounting bolts. Since the connecting plate is equipped with adjustment holes, the distance between the first and second stops, and between the third and fourth stops can be adjusted according to the width of the PVC sheath to be inspected, so as to meet the inspection needs of PVC sheaths of different specifications and improve the availability of the automatic inspection device.

[0020] The following combination Figures 1-2 This application will be described in further detail.

[0021] Example This application discloses an automatic sheath length dimension checking device. (Refer to...) Figure 1It mainly includes a vibrating feeding plate 1, a conveyor belt 2, an image detection module 3, and a defective product sorting module. The feed end of the conveyor belt 2 is connected to the discharge port of the vibrating feeding plate 1. The image detection module 3 is mounted above the conveyor belt 2. A good product collection box 4 is set at the end of the conveyor belt 2 away from the vibrating feeding plate 1. The defective product sorting module is located between the image detection module 3 and the good product collection box 4 and is used to sort defective products that do not meet the length and size requirements.

[0022] In the actual inspection process, the vibrating feeding plate 1 and the conveyor belt 2 work together to automatically drive the PVC sheath through the image detection module 3 at a uniform speed. When the PVC sheath passes through the image detection module 3, the image detection module 3 can automatically collect the image data of the PVC sheath. The image data processor can automatically calculate the length of the PVC sheath based on the image data and determine whether the length of the PVC sheath is qualified.

[0023] If the length of the PVC sheath is within acceptable limits, the defective product sorting module will not operate, and the PVC sheath will continue to be conveyed by conveyor belt 2 to the good product collection box 4; if the length of the PVC sheath is not within acceptable limits, the defective product sorting module will operate and sort the defective products off conveyor belt 2.

[0024] By combining and using the vibrating feeding tray 1, conveyor belt 2, image detection module 3, and defective product sorting module, the technical effect of automatically and comprehensively detecting the length and dimensions of PVC sheaths can be achieved, which is more efficient than manual inspection.

[0025] In this embodiment, the image detection module 3 includes a camera and a light source mounted directly above the conveyor belt 2. The data output terminal of the camera is connected to the image data processor, the data output terminal of the image data processor is connected to the controller, and the signal output terminal of the controller is connected to the defective product sorting module.

[0026] The light source provides the camera with a clear and bright field of view, enabling the camera to capture clear image data of the PVC sheath.

[0027] Reference Figure 1 The defective product sorting module includes a defective product rejection air gun 5 and a defective product channel 6. The entrance end of the defective product channel 6 is fixedly connected to the frame 11 next to the conveyor belt 2 (the frame 11 is not connected to the conveyor belt 2). The defective product rejection air gun 5 is fixedly installed on the frame 11 next to the conveyor belt 2, and the defective product rejection air gun 5 is opposite to the entrance end of the defective product channel 6. The exit end of the defective product channel 6 is provided with a defective product collection box for placing defective PVC sheaths.

[0028] When the length of the PVC sheath fails the inspection and the PVC sheath is judged to be defective, the defective product rejection air gun 5 blows air to send the defective PVC sheath to the defective product channel 6 and sends it out, which can achieve the technical effect of automatic sorting of defective products.

[0029] It should be noted that, in order to facilitate the smooth delivery of the PVC sheath, in this embodiment, the defective product channel 6 is inclined from top to bottom.

[0030] In this embodiment, the frame 11 on both sides of the conveyor belt 2 is equipped with a first limiting channel and a second limiting channel with adjustable width. The defective product channel 6 is located between the first limiting channel and the second limiting channel, and both the first limiting channel and the second limiting channel are erected above the conveyor belt 2. The first limiting channel is located between the defective product channel 6 and the vibrating feeding plate 1, and the second limiting channel is located between the defective product channel 6 and the good product collection box 4.

[0031] The first and second limiting channels allow the PVC sheaths to pass under the camera in an approximately linear array on the conveyor belt 2.

[0032] Reference Figure 1 and Figure 2 The first limiting channel includes a first stop bar 7 and a second stop bar 8 arranged opposite to each other, and the second limiting channel includes a third stop bar 9 and a fourth stop bar 10 arranged opposite to each other. Several connecting plates 71 are fixedly connected to the outer sides of the first stop bar 7, the second stop bar 8, the third stop bar 9 and the fourth stop bar 10. Adjustment waist holes 711 are opened through the several connecting plates 71, and the direction of the adjustment waist holes 711 is arranged along the width direction of the conveyor belt 2.

[0033] Several mounting screw holes are provided on the frame 11 on both sides of the conveyor belt 2. The screw holes are threaded with positioning bolts, and the connecting plate 71 is pressed between the bolt part of the mounting bolt 72 and the frame 11.

[0034] The connecting plate 71 can be fixed by mounting bolts 72. Since the connecting plate 71 is provided with adjustment holes 711, the distance between the first stop bar 7 and the second stop bar 8, and between the third stop bar 9 and the fourth stop bar 10 can be adjusted according to the actual width of the PVC sheath being inspected, so as to meet the inspection requirements of PVC sheaths of different specifications and improve the availability of the automatic inspection device.

[0035] The above are all preferred embodiments of this application, and thus limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
