Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of detection devices, in particular to an optical gasket selecting machine. BACKGROUND

[0002] In the production process of gaskets, gaskets need to go through a key process - selection before entering the inventory. The purpose of this step is to remove gaskets with surface defects such as cracks, pits or defects.

[0003] At present, this process mainly relies on manual operation. Gaskets are placed on a low-speed conveyor belt, and workers on both sides are responsible for inspection. Workers first check one side of the gasket. If no defects are found on this side, they need to manually flip the gasket to check the other side. If both sides are qualified, the gasket will be sent to the counting device by the conveyor belt, and if defects are found, the worker will manually remove it.

[0004] However, the process of manually flipping the gasket not only takes time, but almost every gasket needs to go through this step. Especially for those gaskets with thin thickness and large area, it is more difficult to flip, which further reduces the efficiency of selection. This inefficient workflow not only prolongs the production time, but also increases the production cost. CONTENT OF THE INVENTION

The conveying detection device 2 comprises a front conveying detection assembly 21 and a back conveying detection assembly 22, and the turnover device 3 is located between the front conveying detection assembly 21 and the back conveying detection assembly 22.

[0033] When the gasket is detected, the gasket is placed on the feeding device 1, the gasket is placed on the front conveying detection assembly 21 one by one through the feeding device 1, the front conveying detection assembly 21 conveys the gasket to detect the front surface of the gasket, after the front surface detection of the gasket is completed, the front conveying detection assembly 21 conveys the gasket to the turnover device 3, the gasket is conveyed to the back conveying detection assembly 22 through the turnover device 3, and the gasket is turned over, so that the back conveying detection assembly 22 conveys the gasket and detects the back surface of the gasket through the back conveying detection assembly 22.

[0034] The feeding device 1 comprises a feeding detection assembly 11 and a feeding assembly 12, and the feeding assembly 12 is provided with at least one group.

[0035] In the embodiment of the application, the feeding assembly 12 is provided with two groups. The two groups of feeding assemblies 12 alternately convey the gasket to the feeding detection assembly 11, and the size and shape of the gasket are detected through the feeding detection assembly 11, after the detection of the feeding detection assembly 11 is completed, the feeding detection assembly 11 conveys the gasket to the conveying detection device for detection.

[0036] The feeding assembly 12 comprises a hopper 121 and a hopper discharge unit 122, and the hopper 121 is provided with a discharge port close to one side of the feeding detection assembly 11.

[0037] The gaskets are placed in the hopper 121 in batches, and when the gaskets are output, the gaskets inside the hopper 121 are transported one by one to the feeding detection assembly 11 by the hopper discharge unit 122. The multiple feeding assemblies 12 cooperate with each other to improve the feeding speed of the gaskets.

[0038] The hopper 121 includes a pair of adjustable spacing positioning parts 1211, the positioning part 1211 includes a conveying plate 1212, a first positioning strip 1213 and a second positioning strip 1214, and a gap between the bottom end of the second positioning strip 1214 and the hopper discharge unit 122 forms a discharge port. The spacing between the bottom end of the second positioning strip 1214 and the hopper discharge unit 122 is adjustable.

[0039] The spacing between the two positioning parts 1211 is adjusted according to different sizes and models of the gaskets, so that the two first positioning strips 1213 and the two second positioning strips 1214 cooperate with each other to cooperatively clamp the gaskets.

[0040] The hopper discharge unit 122 includes a conveying table 1221 and a pushing plate 1222. The pushing plate 1222 is inserted and matched with the discharge port by a pushing plate 1222 power source. In the embodiment of the application, the pushing plate 1222 power source is a gas cylinder, and the pushing plate 1222 is pushed to the feeding detection assembly 11 by the gas cylinder.

[0041] In order to facilitate the adaptation to gaskets of different thicknesses, the second positioning strip 1214 can be slidably matched with the conveying table 1221 in the vertical direction, so as to adjust the height of the discharge port, thereby facilitating the adaptation to discharge ports of different heights.

[0042] The feeding detection assembly 11 includes a detection table 111 and a pushing block 112. The detection table 111 is provided with a visual detection device, so as to detect the size of the gaskets on the detection table 111 and whether the gaskets are missing. The pushing block 112 moves relative to the detection table 111 by a pushing block 112 power source. In the embodiment of the application, the pushing block 112 power source is a gas cylinder, and the gas cylinder pushes the gaskets on the detection table 111 to the conveying detection device 2 by the pushing block 112.

[0043] The front conveying detection assembly 21 includes a front conveying belt 211, a front gasket surface detection part 212 and a front removal part 213. The front gasket surface detection part 212 is located close to the front conveying belt 211, and is used for detecting defects on the front surface of the gaskets. In the embodiment of the application, the front gasket surface detection part 212 is a visual detection device.

[0044] The front removal part 213 is located close to the discharge end of the front conveying belt 211, and the unqualified gaskets are pushed out of the front conveying belt 211.

[0045] The front surface cleaning part 213 comprises a cleaning block 2131 and a collection box 2132. The cleaning block 2131 and the collection box 2132 are located on both sides of the front surface conveying belt 211. The cleaning block 2131 pushes the unqualified gasket out of the front surface conveying belt 211 by a cleaning block power source, and makes the unqualified gasket fall into the collection box 2132 for collection.

[0046] The back surface conveying detection assembly 22 comprises a back surface conveying belt 221, a back surface gasket surface detection part, and a back surface cleaning part.

[0047] The back surface conveying belt 221 is located below the front surface conveying belt 211. The back surface gasket surface detection part is located close to the back surface conveying belt 221. The back surface cleaning part is located close to the discharge end of the back surface conveying belt 221. The structure and function of the front surface gasket surface detection part 212 and the back surface gasket surface detection part are consistent. The structure and function of the front surface cleaning part 213 and the back surface cleaning part are consistent.

[0048] The turnover device 3 comprises a guide plate 31 and a mounting frame 32.

[0049] The feeding end of the guide plate 31 is close to the discharge end of the front surface conveying belt 211. The discharge end of the guide plate 31 is located close to the back surface conveying belt 221. In order to improve the stability of the gasket movement, the guide plate 31 is an arc-shaped plate. The guide plate 31 is installed at the discharge end of the front surface conveying belt 211 through the mounting frame 32.

[0050] The included angle between the conveying direction of the front surface conveying belt 211 and the conveying direction of the back surface conveying belt 221 is not greater than 90°. In the embodiment of the present application, the conveying direction of the front surface conveying belt 211 and the conveying direction of the back surface conveying belt 221 are perpendicular. In this way, the stability of the gasket conveying onto the back surface conveying belt 221 is improved. The possibility that the conveying direction of the back surface conveying belt 221 and the direction of the gasket conflict, resulting in the failure of the gasket turnover, is reduced.

[0051] The implementation principle of the optical gasket selection machine in the embodiment of the present application is as follows: the gasket is sent to the conveying detection device 2 through the feeding device 1. The front surface conveying detection assembly 21 detects the front surface of the gasket. Then, the turnover device 3 turns over the gasket.
