DETAILED DESCRIPTION

[0030] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the utility model will be briefly introduced below in combination with the drawings and the descriptions of the embodiments or the prior art. Obviously, the following descriptions of the structures of the drawings are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0031] The following will describe the technical solution provided by the present invention in detail by way of embodiments with reference to the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0032] In some instances, some embodiments are not described or not described in detail because they belong to existing or conventional technologies.

[0033] In addition, the technical features recorded in this article, or the steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can also be combined in any suitable manner in one or more embodiments. For those skilled in the art, it is easy to understand that the steps or operation sequence of the methods related to the embodiments provided herein can also be changed. Any order in the drawings and embodiments is only for illustrative purposes and does not imply a requirement to follow a certain order unless it is explicitly stated that a certain order is required.

[0034] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, under reasonable circumstances (not constituting a self-contradiction), include direct and indirect connections (couplings).

[0035] See also Figure 1 The detection system of this embodiment includes a platen 60 and a conveyor 10, a first visual system 20, a probe 30, a good product container 40 and a defective product container 50 all arranged on the platen 60, and also includes a robot 80 for transferring products between the conveyor 10, the first visual system 20, the probe 30, the good product container 40 and the defective product container 50; a second visual system 70 is arranged directly above the conveyor 10; the second visual system 70 is used to determine the orientation of the product in the conveyor 10 to guide the robot 80 to pick up the product in the conveyor 10; the first visual system 20 is used to determine the orientation of the hole of the product on the robot 80 to guide the robot 80 to align the hole of the product with the probe 30; the good product container 40 is used to hold products that have passed the test; the defective product container 50 is used to hold products that have failed the test.

[0036] When in use, the operator only needs to place the product on the conveyor 10. Since the second visual system 70 is set to detect the position of the product on the conveyor 10, the operator does not have to place the product in a specific position, which is more efficient. After the second visual system 70 detects the position of the product on the conveyor 10, the coordinate information of the product and its position are sent to the robot 80. The robot 80 picks up the product on the conveyor 10 and moves the product directly above the first visual system 20. The first visual system 20 sends the hole position coordinate information on the product to the robot 80. The robot 80 then moves the product to the probe 30, and aligns the holes of the product with the probe 30 one by one for testing according to the hole position coordinate information provided by the first visual system 20. For qualified products, the robot 80 places them in the good product container 40; for unqualified products, the robot 80 places them in the defective product container 50.

[0037] See also Figure 2 In order to protect the safety of the operator and to prevent the ambient light from affecting the shooting effect of the first visual system 20 and the second visual system 70, so as to reduce the probability of misjudgment, the detection system of this embodiment also includes a protective cover 110 covering the outside of the table 60; the first visual system 20, the second visual system 70, the probe 30, the good product container 40 and the bad product container 50 are all located in the protective cover 110; a part of the conveyor 10 extends outside the protective cover 110, so that the operator can operate outside the protective cover 110. The protective cover 110 is fixed to the table 60 by a profile bracket, and the windows on the protective cover 110 are made of brown or black acrylic plates to prevent or reduce natural light from entering the inside of the protective cover 110.

[0038] See also Figure 1 The detection system of this embodiment may also include a transfer base 90 for positioning and clamping the product, and the manipulator 80 includes a body 81 and an end tool 82 disposed at the end of the body 81; Figure 3The end tool 82 includes a vacuum suction head 821 for sucking products and a clamping claw 822 for clamping products; the clamping claw 822 includes a finger cylinder 8221 and two copper blocks 8222 respectively arranged on two fingers of the finger cylinder 8221; the two copper blocks 8222 form an electrical circuit with the probe 30 through wires; the manipulator 80 is used to suck products from the conveyor 10 through the vacuum suction head 821 and place them on the intermediate transfer base 90, and is used to clamp products from the intermediate transfer base 90 through the clamping claw 822 and move them to the probe 30, the good product container 40 and the defective product container 50. Since the products are randomly placed on the conveyor 10, and the products on the conveyor 10 may be close to each other, it is not convenient to pick up the products by clamping. However, when the product is in contact with the probe 30 and measured, the probe 30 will exert an elastic force on the product, and vacuum suction of the product for testing may cause the product to shift, resulting in the failure to align the probe 30 when measuring the next hole. Therefore, in this embodiment, two picking devices are set, one is a vacuum suction method, and the other is a clamping method; and an intermediate transfer seat 90 is set, and the manipulator 80 first sucks the product from the conveyor 10 to the intermediate transfer seat 90 by vacuum suction, and then clamps the product on the intermediate transfer seat 90 by the clamp 822; it is convenient to pick up the product from the conveyor 10, and it is convenient for the probe 30 not to shift during testing. The copper block 8222 and the probe 30 are connected to the test equipment, such as LCR meter, withstand voltage insulation tester, etc. through wires, so as to form an electrical circuit.

[0039] See also Figure 4 In this embodiment, the finger and the copper block 8222 are connected by an insulating connection structure; the insulating connection structure includes a connecting screw 8223, an insulating block 8224, an insulating bushing 8225 and a connecting block 8226; the connecting block 8226 is provided with a connecting hole that matches the insulating bushing 8225, and the insulating block 8224 is located between the finger and the connecting block 8226; the end of the insulating bushing 8225 away from the insulating block 8224 has a flange 82251, and the flange 82251 is located on the side of the connecting block 8226 away from the insulating block 8224; the connecting screw 8223 passes through the insulating bushing 8225 and the insulating block 8224 in sequence and is threadedly connected to the finger; the copper block 8222 is fixed to the connecting block 8226. By providing an insulating connection structure, the copper block 8222 is isolated from the finger cylinder 8221 to avoid leakage. The insulating bushing 8225 is inserted into the connecting hole to isolate the connecting screw 8223 from the connecting block 8226 , and the insulating block 8224 isolates the connecting block 8226 from the finger, thereby achieving insulation between the copper block 8222 and the finger cylinder 8221 .

The first pin 8215 fixes the first connecting column 8212 to the middle block 8211; the second pin 8216 limits the distance of the second connecting column 8213 sliding up and down; by setting the spring, the vacuum suction head 821 can form a buffer when contacting the product to avoid direct hard contact and damage to the product. The first connecting column 8212, the second connecting column 8213 and the spring are all hollow, so that the vacuum can reach the suction plate 8217, thereby sucking the product. It should be noted that although the first connecting column 8212 and the middle block 8211, the second connecting column 8213 and the middle block 8211 are all clearance-matched, the clearance is very small, so there will be no air leakage.

Since the positioning plate 92 is positioned and matched with the positioning base 91 through the first positioning structure, different specifications of products can be adapted by replacing different positioning plates 92, thereby improving the versatility of the detection system. The first positioning structure can be a slot structure, or a positioning pin structure. In this embodiment, refer to Figure 6The positioning base 91 includes a bottom plate 911 fixed to the table 60 and four columns 912 fixed to the bottom plate 911; the four columns 912 are distributed in a rectangular shape; at least two columns 912 are positioned and matched with the positioning plate 92.
