Description

Technical Field

[0001] The present invention relates to the technical field of electronic component detection, in particular to an electronic component automatic detection instrument and a detection method. Background Art

[0002] As a kind of electronic component, relay is a key component that converts electrical signals into mechanical actions. It is widely used in various electrical equipment, such as home appliances, automotive electronics, industrial control systems, etc. Its working principle is to control the on and off of large current circuits through a small current. Therefore, it has extremely high requirements on the reliability and stability of relays. Therefore, in the process of relay production and manufacturing, the relay's multiple performances will be tested through testing equipment to ensure its stability in subsequent use, and then ensure the stability and safety of the entire system.

[0003] Among them, appearance inspection, as one of the relay performance inspections, usually uses automatic inspection equipment based on CCD camera photography. The equipment uses CCD cameras to capture images of relays and combines image processing algorithms and machine learning skills to achieve non-contact measurement of relay appearance and mechanical properties to ensure the quality of relays, including defects such as shell cracks, missing labels, poor welding layers, bent or missing pins, etc.

[0004] At present, automatic detection equipment based on CCD camera photography usually needs to set up an independent detection position in the relay production line, then install the automatic detection equipment at the detection position, and transport the relay to the detection position for photography and detection through intermittent transportation of the conveyor line. The overall working stability is relatively high, but it will make the relay production line longer and increase the floor space of the production line; and usually a robot is required to grab the relay on the carrier board and place it on the conveyor line, and then the conveyor line transports it. After the photography is completed, another robot grabs the relay on the conveyor line and sends it to the next process. The whole process is relatively complicated and will directly reduce the production efficiency of the entire production line; at the same time, the CCD camera is directly fixed on the mobile base. When a non-high-precision transmission mechanism is used to control the mobile base to move to the detection position, the CCD camera is prone to position deviation due to transmission inertia, and the position deviation will affect the accuracy of the detection result. Summary of the invention

[0005] The present invention provides an automatic detection instrument and a detection method for electronic components to solve the problems in the related art that the automatic detection equipment needs to set up an independent detection position in the production line, which makes the relay production line longer and increases the floor space, and requires a robot to grab the relay for transportation before and after taking pictures, resulting in low production efficiency and low detection accuracy.

[0007] In one possible implementation, the reference positioning member is a circular structure and is symmetrically distributed and fixed on both sides of the movable seat two, respectively; reference limit members are symmetrically arranged on the working position and the detection position, and the reference limit members in the working position and the detection position correspond one-to-one to the reference positioning member; the reference limit member includes a mounting seat symmetrically arranged with a base, a limit track is installed on the mounting seat, the symmetrical bases are slidably installed on the limit track, and an elastic member two is connected between the base and the mounting seat, arc-shaped limit grooves are provided on the opposite surfaces of the symmetrical bases, the stabilizing member corresponds one-to-one to the base on the corresponding detection position or the working position, and the stabilizing member is installed on the movable seat one, and when the movable seat one moves to the corresponding working position or the detection position, the stabilizing member presses against the corresponding base, wherein a limit body is arranged on the mounting seat, and the limit body limits the sliding range of the base.

[0008] In a possible implementation, the stabilizing member includes a connecting frame and an arc-shaped abutting end, and the abutting end is fixedly connected to the movable seat through the connecting frame.

[0009] In a possible implementation, a gear rack set is connected between the symmetrical bases, and the gear rack set enables the symmetrical bases to move synchronously in opposite directions.

[0010] In a possible implementation, a stabilizing frame is provided between the movable base and the conveying seat, and the stabilizing frame is fixedly connected to the movable base and slidably connected to the conveying seat.

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0025] See also Figure 1 , Figure 2 and Figure 3 An automatic detection instrument for electronic components includes a conveying seat 2 on which a clamping head 1 is movably installed. The conveying seat 2 includes a transverse seat 21 and a longitudinal seat 22. The longitudinal seat 22 is slidably installed on the transverse seat 21 up and down, and the transverse seat 21 moves forward and backward. The clamping head 1 is installed on the longitudinal seat 22. The components 3 are placed in rows on a carrier plate 8. A movable base 4 is installed on the transverse seat 21 for left and right movement. A detection head 5 is installed on the movable base 4. The detection head 5 reciprocates and moves intermittently back and forth. During the detection process, the longitudinal seat 22 first drives the clamping head 1 to move downward, and the clamping head 1 clamps the components 3 in a row, and then the longitudinal seat 22 moves upward and resets. During the upward and reset process, the movable base 4 moves left into the working position. , the detection head 5 is just located directly below the corresponding component 3. Then, the transverse seat 21 moves to transport the component 3 to the next processing step. During this process, the detection head 5 moves intermittently in the front-to-back direction and stops at the corresponding detection position to take pictures of the component 3. The detection position corresponds to the component 3 one by one. When the detection head 5 is located at the detection position, it is just located directly below the corresponding component 3. In summary, the process of using the clamping head 1 to clamp, pick up and transport the component 3 to take pictures and detect the component 3 is compared with the existing front and rear two manipulators combined with the conveyor line to intermittently transport the component 3 for photo inspection, which effectively simplifies the production process of the component 3, improves the production efficiency of the production line and reduces the floor space of the production line. It should be noted that the detection head 5 is an existing high-precision CCD visual camera. The CCD visual camera captures the image of the material box by taking pictures. After taking pictures, the CCD visual camera sends the recognized image to the image processing software in the system. The image processing software is used to process and analyze the image data. According to the results of the image processing, the system will make a qualified or unqualified judgment. If defects are found, an alarm can be triggered, information can be recorded, or the existing automatic rejection device can be started to remove unqualified products.

[0026] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7A control component 6 is provided between the mobile base 4 and the conveying seat 2, and between the detection head 5 and the mobile base 4. The control component 6 includes a mobile seat 1 61, a mobile seat 2 62, a reference positioning member 63 and a reference limiting member 64. The mobile seat 2 62 is slidingly installed on the mobile seat 1 61 and an elastic member 1 65 is provided between the two. A stabilizing member 66 is provided between the mobile seat 1 61 and the reference limiting member 64. The reference positioning member 63 is fixedly installed on the mobile seat 2 62, and the reference limiting member 64 is respectively installed on the mobile base 4 and the transverse seat 21; taking the control component 6 provided between the mobile base 4 and the detection head 5 and used to control the intermittent movement of the detection head 5 as an example, the mobile seat 1 61 is slidingly installed on the mobile base 4 front and back, and the detection positions are distributed from front to back. There are a number of reference limiting members 64, which are respectively arranged at corresponding detection positions, and the detection head 5 is fixedly installed on the mobile seat 2 62.

[0027] During the photo detection process, the moving seat 1 61 moves intermittently from front to back and passes through the detection position in turn and stays briefly at the detection position. During this process, the moving seat 2 62 moves accordingly under the suppression of the elastic member 1 65, and can undergo a certain degree of relative displacement under the state of force. When the moving seat 2 62 enters the detection position, the reference limit member 64 will automatically perform a preliminary limit on the reference positioning member 63, and then as the moving seat 1 61 stops moving, the stabilizing member 66 will press the reference limit member 64, so that the reference positioning member 63 is firmly and accurately in the detection position, and correspondingly, the detection head 5 thereon is accurately and stably located at the detection position and takes photos. After completing the photo work, the moving seat 1 61 continues to move, and the stabilizing member 66 releases the pressing state of the reference limit member 64, and then the reference positioning member 63 automatically moves out of the limiting area of ​​the reference limit member 64 and enters the next detection position as the moving seat 2 62 moves and repeats. In summary, the above-mentioned working process, the control component 6 can stably and accurately control the intermittent movement of the detection head 5 and stably and accurately locate it in the detection position to perform photo detection work. Similarly, the moving seat 1 61 in the control component 6 located between the moving base 4 and the conveying seat 2 and used to control the left and right reciprocating movement of the moving base 4 is slidably installed on the transverse seat 21, and the moving base 4 is fixedly installed on the moving seat 2 62. The control component 6 can stably and accurately control the moving base 4 to move to the work station, thereby providing a stable and reliable working environment for the detection work of the detection head 5, and avoiding the detection head 5 from easily deviating from its position due to transmission inertia when a transmission mechanism including a non-high-precision motor or other non-high-precision driving source is used to control the detection head 5 to move to the detection position, thereby affecting the accuracy of the detection result; wherein, a sliding limit groove 67 is provided on the moving seat 1 61 in the control component 6 used to control the intermittent movement of the detection head 5, such as Figure 4As shown, the sliding range of the second moving seat 62 is limited by the sliding limit groove 67, so that the second moving seat 62 is limited and slidably mounted on the first moving seat 61. The second moving seat 62 in the control assembly 6 for controlling the reciprocating movement of the moving base 4 is fixedly connected with a limit block 68, as shown in FIG. Figure 7 As shown, the limit blocks 68 are symmetrically distributed and respectively located on the left and right sides of the moving seat 1 61 , and limit the sliding range of the moving seat 2 62 by cooperating with the moving seat 1 61 , so that the moving seat 2 62 is limitedly slidably installed on the moving seat 1 61 .

[0028] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6The reference positioning member 63 is a circular structure and is symmetrically distributed and fixed on both sides of the second movable seat 62. The reference limiting member 64 on the detection position is symmetrical on the left and right, and the reference limiting member 64 on the working position is symmetrical front and back. The reference limiting members 64 on the detection position and the working position correspond to the reference positioning member 63 one by one. The reference limiting member 64 includes a mounting seat 642 with a base 641 symmetrically arranged on the upper and lower sides. A limiting track 643 is installed on the mounting seat 642. The symmetrical bases 641 are slidably installed on the limiting track 643, and an elastic member 644 is connected between the base 641 and the mounting seat 642. The symmetrical base 641 has arc-shaped limit grooves 645 on its opposite surfaces, and the stabilizer 66 corresponds to the base 641 one by one, and the stabilizer 66 is fixedly mounted on the moving seat 1 61; taking the reference limiter 64 on the detection position as an example, the mounting seat 642 is fixedly mounted on the moving base 4, and when the moving seat 1 61 moves to the corresponding detection position and is about to stop, the reference positioning member 63 enters between the symmetrical bases 641. At this time, the base 641 flexibly clamps the reference positioning member 63 under the action of the elastic member 2 644, and inhibits the moving seat 2 62 from moving synchronously with the moving seat 1 61 through the reference positioning member 63. The movable seat 1 61 moves and acts as a buffer, and then the movable seat 1 61 stops moving. At this time, the stabilizing member 66 presses against the corresponding base 641, so that the base 641 presses and fixes the reference positioning member 63, and the reference positioning member 63 is rigidly clamped and fixed. At this time, the reference positioning member 63 is quickly, firmly and accurately in the corresponding detection position under the limit fixation of the base 641, that is, the movable seat 2 62 and the detection head 5 are quickly and accurately in the detection position, which is convenient for the detection head 5 to quickly and stably take pictures of the components 3 on the detection position, and then the image information of the components 3 can be accurately and reliably obtained, thereby improving the reliability of the detection results. When the detection head 5 finishes taking pictures, the moving seat 61 continues to move, and the stabilizing member 66 releases the tightness on the base 641, and then the moving seat 2 62 and the reference positioning member 63 continue to move with the moving seat 61; the mounting seat 642 in the reference limit member 64 on the working position is fixedly installed on the transverse moving seat 21, and the reference limit member 64 is an integrated unit that can be pre-assembled as a prefabricated part, and then installed on site, wherein a limit body 646 is arranged on the mounting seat 642, and the limit body 646 limits the sliding range of the base 641, thereby further ensuring the stability and reliability of the entire working process.

[0029] See also Figure 4 , Figure 5 and Figure 7 The stabilizing member 66 includes a connecting frame 661 and an arc-shaped abutting end 662. The connecting frame 661 is fixedly connected to the movable seat 61, and the abutting end 662 is fixedly connected to the connecting frame 661. When the movable seat 61 moves to the detection position and stops, the abutting end 662 abuts against the corresponding base 641 to limit the base 641. Figure 4and Figure 5 As shown, as the movable seat 1 61 moves to the detection position, the tightening end 662 will contact the base 641 and move the base 641 toward the middle reference positioning member 63, so that the symmetrical base 641 clamps and fixes the reference positioning member 63 from the upper and lower sides, and the corresponding movable seat 2 62 is firmly and accurately located at the detection position, and the working process of the stabilizing member 66 at the working position is the same.

[0030] See also Figure 4 and Figure 5 A gear rack set 647 is connected between the upper and lower symmetrical bases 641. The gear rack set 647 enables the symmetrical bases 641 to move synchronously in the opposite direction. The gear rack set 647 includes two racks and a gear. The gear is rotatably mounted on the mounting seat 642. The racks are fixedly connected to the symmetrical bases 641 respectively, and the two racks are meshed with the gears and are respectively located on both sides of the gears. The symmetrical bases 641 are synchronously moved in the opposite direction through the gear rack set 647. On the one hand, it is beneficial to improve the positioning accuracy of the reference positioning member 63, and on the other hand, it is beneficial to improve the stability and reliability of the working process of the overall structure.

[0031] See also Figure 1 , Figure 2 and Figure 7 A stabilizing frame 7 is provided between the mobile base 4 and the conveying seat 2. The stabilizing frame 7 is fixedly connected to the mobile base 4 and slidably connected to the conveying seat 2. The stabilizing frame 7 is used to further improve the stability of the mobile base 4 during the movement process.

[0032] See also Figure 1 and Figure 2 The clamping head 1 includes a unified connecting seat 101, which is fixedly mounted on the longitudinal displacement seat 22. A plurality of control cylinders 102 are mounted on the unified connecting seat 101. The control cylinders 102 are evenly distributed from front to back. Clamps 103 are symmetrically mounted on the control cylinders 102. The control cylinders 102 correspond to the components 3 one by one. The control cylinders 102 are bidirectional cylinders and control the symmetrical clamps 103 to move synchronously in opposite directions to complete the picking and placing of the components 3.

[0033] See also Figure 1 , Figure 2 and Figure 6 The elastic member 1 65 between the moving seat 1 61 and the moving seat 2 62 is symmetrically arranged and respectively located on both sides of the moving seat 2 62, and the symmetrically arranged elastic member 1 65 is distributed along the sliding direction of the moving seat 2 62, such as Figure 6As shown, taking the moving seat 1 61 on the moving base 4 and the moving seat 2 62 as examples, the number of elastic members 1 65 is four and they are evenly divided into two groups. The two groups of elastic members 1 65 are symmetrically distributed front to back and are respectively located on the front and back sides of the moving seat 2 62. By using the elastic members 1 65, the moving seat 2 62 is in a flexibly connected state, thereby fully improving the stability of the position state of the moving seat 2 62 and correspondingly improving the stability of the entire working process.
