Description

Technical Field

[0001] The present invention relates to the technical field of electronic device manufacturing, and specifically relates to an insertion jig applicable to components of different specifications. Background Art

[0002] AOI (Automated Optical Inspection) equipment is based on the optical principle to detect common defects encountered in welding production. AOI is a newly emerging testing technology, and many manufacturers use AOI inspection equipment. When the AOI equipment automatically inspects a circuit board, the machine automatically scans and acquires images through a camera, compares them with the qualified parameters in the database, checks for defects through image processing, and displays the defects through a monitor for maintenance personnel to repair.

[0003] Before using the AOI equipment to inspect a circuit board, it is necessary to first inspect the components that have not been soldered onto the circuit board to ensure the integrity of the components. The prior art is to place the components on the bottom plate of the insertion jig, use a movable plate to fix the components of the same specification, and then use the AOI equipment to inspect the components in the insertion jig. However, this insertion jig has the following problems: 1. Some components with pins will be supported by the pins when placed on the bottom plate, resulting in different heights from the components without pins, which will affect the testing effect; 2. During the testing process, multiple components will be tested simultaneously. Since the testing equipment will scan the components, if the components are too close, there will be test deviations and false alarm points. If they are too far away, the number of installed components is small, and the testing efficiency is low; 3. The movable plate for fixing the components is a whole, and it can only adapt to the clamping of components of the same specification during a single test. When the specifications of the components to be tested are different, multiple tests are required, and the efficiency is relatively low. Therefore, in view of the above problems, it is necessary to develop an insertion jig applicable to components of different specifications. Summary of the Invention

[0004] In view of the above deficiencies of the prior art, the present invention provides an insertion jig applicable to components of different specifications. The distance between the support bars in multiple groups of support mechanisms can be adjusted, so that the distance between the components on the support bars is within the test range of the test equipment, ensuring the accuracy of the test, and at the same time ensuring the number of components to be tested and improving the test efficiency; multiple groups of fixing mechanisms correspond to the multiple groups of support mechanisms one by one and can be fixed independently. The multiple groups of support mechanisms can respectively place components of different specifications, so as to realize the simultaneous inspection of components of different specifications.

[0005] To achieve the above object, the present invention is realized through the following technical solutions: An insertion jig applicable to components of different specifications, including a bottom plate, on which a plurality of installation grooves are opened and a plurality of detection points are provided.

The first screw passes through the second through hole and the first through hole and is screwed into the threaded hole. The first movable plate is located between the bottom plate and the three support bars. Moving the pressing block can drive the first screw and the first movable plate to move in the first through hole to fix the components on the three support bars.

The pair of limiting columns 14 can be inserted into the corresponding second limiting holes 15. Pushing the second movable plate 12 can make the pair of limiting columns 14 and the connecting sliding grooves 11 of the pair of side support bars 7 move to adjust the gap between the three support bars 7.

The multiple groups of fixing mechanisms are installed on the bottom plate 1 and can respectively fix the components in each group. The insertion jig is installed on the detection device to detect the components; Each group of fixing mechanisms includes a first screw 5, a pressing block 4 and a first movable plate 6. A plurality of elongated first through holes are formed in the bottom plate 1.

[0025] The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, which are as follows:

[0026] According to the attached Figures 1-3 As can be seen from the description, when the present invention is in use, first, each group of support mechanisms is adjusted. Since the sliders 19 fixedly connected to both sides of the second movable plate 12 are slidably connected to a pair of I-shaped slide bars 13 provided on the bottom plate 1, and the two ends of the side support bars 7 on both sides of the middle support bar 7 are slidably connected to the connection sliding grooves 11 fixed to the lower bottom surface of the bottom plate, and at the same time, the limit posts 14 on the side support bars 7 are slidably arranged in the inclined second limit holes 15 on the second movable plate 12. Therefore, by pushing the second movable plate 12, the edge of the second limit hole 15 can drive the limit posts 14 and the side support bars 7 to move. Since the second limit hole 15 and the side support bar are at a 45° angle and are symmetrically arranged with the center line of the middle support bar 7 as the axis of symmetry, the side support bars 7 will move towards or away from the middle support bar 7 at the same time, thereby changing the gap between the three support bars 7. Secondly, the components to be detected of the same specification are arranged in the same installation groove 8, and the components straddle the three support bars 7 in each group of support mechanisms, so that the components are attached above the support bars, and the pins of the components can straddle both sides of the support bars to ensure equal height after installation and ensure the accuracy of the test. At the same time, the gap between the three support bars 7 is adjusted to keep an appropriate distance between the components to be detected, so that the distance between the components on the support bars is within the test range of the test equipment, ensuring the accuracy of the test and avoiding too large a spacing, resulting in a small number of tests and affecting the test efficiency. Thirdly, multiple groups of support mechanisms can respectively place components of different specifications. Multiple groups of fixing mechanisms correspond to multiple groups of support mechanisms one by one and can be operated independently to fix the components on each group of support bars 7, so as to realize the simultaneous detection of components of different specifications and improve the applicability. Finally, the entire insertion jig is installed on the AOI equipment to detect the components.

[0027] Among them, when moving the pressing block 4 in each set of fixing mechanisms, the pressing block 4 drives the first screw 5 to move in the first through-hole, and the first screw 5 drives the first movable plate 6 screwed thereto to move, so that one end of the component on each set of support bars 7 abuts against the side wall of the installation groove 8, and the other end abuts against the first movable plate 6. Release the pressing block 4, press the pressing block 4 onto the first through-hole to fix the first movable plate 6, and the first movable plate 6 fixes the component to prevent the component from falling off and loosening during the detection process. In particular, limiting structures are provided on both sides of the first movable plate 6 parallel to the moving direction, and the way of using a sliding body and a sliding rail can be adopted to ensure the stability of the movement of the first movable plate 6. This way is the prior art and is not shown in the figure.

[0028] Among them, a plurality of limiting blocks 16 are installed at both ends of the plurality of I-shaped sliding bars 13 to ensure that the entire support mechanism does not fall off when the slider 19 slides on the I-shaped sliding bars 13.

[0029] Among them, a plurality of push rods 17 are fixedly connected to the plurality of second movable plates 12, which is convenient for pushing the second movable plates 12, so as to adjust the gap of the support bars 7 and keep an appropriate distance between the components installed on them.

[0030] Among them, the fixing mechanism and the support mechanism are 4 to 6 groups, which increases the number of components detected at one time, thereby improving the detection efficiency.

[0031] Among them, a spring 18 is arranged between the pressing block 4 and the nut of the first screw 5. Lift and move the pressing block 4 to drive the first movable plate 6 to move. After fixing the component, put down the pressing block 4, and the spring 18 stretches to push the first screw 5 upward to make the first movable plate 6 close to the bottom plate 1 without loosening.

[0032] Among them, the pressing block 4 is T-shaped, and the vertical end of the T-shaped pressing block 4 is embedded in the first through-hole, so that the pressing block 4 further fixes the first movable plate 6.

[0033] Among them, a guide block 2 is arranged between the horizontal end of the pressing block 4 and the bottom plate 1. The guide block 2 is fixedly installed on the bottom plate 1 and a guide hole is opened at the position corresponding to the first through-hole. The vertical end of the pressing block 4 is embedded in the guide hole and the first through-hole, so that the pressing block 4 fixes the first movable plate 6 more firmly.
