Description

Technical Field

[0001] The present invention is applied to the field of product testing linkage fixtures, and particularly relates to a product multi-action linkage fixture. Background Art

[0002] In the current field of automated testing, especially in the testing process of 3C products such as electronic products, how to efficiently and accurately complete multiple test actions has become an urgent problem to be solved. At present, we need to perform the preparatory actions of flattening, clamping, pricking and clearing the test space for a mobile phone button before testing. Due to the small space of the machine, it is difficult to achieve the four sets of actions of flattening, clamping, pricking and clearing the test space after placing the product while maintaining the motion accuracy. In order to ensure the realization of these four sets of actions in a small space, a linkage structure needs to be designed to connect the four sets of actions in series.

[0003] The existing action linkage structure generally uses a connecting rod connection as the transmission mechanism. When the space is small and the parts are many, there are more components and kinematic pairs, which leads to larger cumulative errors. At the same time, the motion accuracy and efficiency will be low, which will cause the product test position to be too different from the ideal one, resulting in a low test pass rate.

[0004] Therefore, based on the above problems, if a product multi-action linkage fixture can be designed, which has the advantages of simple structure, convenient operation, moderate cost and the ability to achieve multi-action linkage, it can be pushed by a cylinder to fully link other action mechanisms, and by controlling the movement of the slide rail assembly, ensure the product's movement accuracy during flattening, clamping, needle insertion and clearing the test space, thereby improving the pass rate of product testing, which can solve the above problems well.

The active end of the linkage cylinder 21 pushes the Y-direction block module 22, the pressure block assembly module 23 and the side pressure module 24 to cooperate with the product component. It can be seen that the fixture carrier 1 supports and limits the product components and the multi-action linkage module 2, and the large fixed block 20 supports and limits the linkage cylinder 21, the Y-axis block module 22, the pressure block assembly module 23 and the side pressure module 24.

[0017] like Figure 6 As shown, in the present embodiment, the multi-action linkage module 2 further includes a first slide rail 25, a linkage block 26, a linkage plate 27 and a linkage rod 28. The first slide rail 25 is fixedly fitted on the large fixed block 20. The linkage block 26 is connected and fitted with the movable end of the linkage cylinder 21.

The linkage rod 28 is limitedly fitted with the side pressure module 24. The linkage plate 27 is fitted with the pressure block assembly module 23 and the Y-direction stop block module 22. It can be seen that the first slide rail 25 plays a role of limiting and guiding when the movable end of the linkage cylinder 21 pushes the linkage block 26 and the linkage plate 27 to move, so that the linkage block 26 and the linkage plate 27 move more smoothly. During movement, the linkage rod 28 pushes the side pressure module 24, and the linkage plate 27 pushes the pressure block assembly module 23 and the Y-direction block module 22 respectively, so that the side pressure module 24, the pressure block assembly module 23 and the Y-direction block module 22 are respectively limited and matched with the product components.

[0018] like Figure 4As shown, in this embodiment, the lifting module 12 includes a lifting movable plate 130, a plurality of large guide columns 131 and a linear bearing 132, and the plurality of large guide columns 131 are fixedly fitted on the fixture carrier 1, and the lifting movable plate 130 is slidably fitted with the plurality of large guide columns 131 through the linear bearing 132, and a lifting column 133 and a pair of first limiting spring columns 134 are provided on the lifting movable plate 130, and the lifting column 133 is limitedly fitted with the flip module 11, and the first limiting spring column 134 is limitedly fitted with the fixture carrier 1, and a second limiting spring column 13 is provided on the fixture carrier 1, and the second limiting spring column 13 is limitedly fitted with the bottom of the lifting movable plate 130. It can be seen that the plurality of large guide columns 131 limit the movement of the lifting movable plate 130, the lifting movable plate 130 supports and fixes the linear bearing 132, the lifting column 133 and a pair of the first limiting spring columns 134, the linear bearing 132 guides and lubricates the movement of the lifting movable plate 130, the lifting column 133 lifts the flip module 11, the first limiting spring column 134 buffers and limits the upward movement of the lifting movable plate 130, the jig carrier 1 supports and fixes the second limiting spring column 13, and the second limiting spring column 13 buffers and limits the downward movement of the lifting movable plate 130.

[0019] like Figure 7 and Figure 8As shown, in this embodiment, the Y-axis block module 22 includes a support frame 220, a moving block 221, a movable oblique wedge block assembly and a plurality of first small guide columns 222, a plurality of the first small guide columns 222 are limitedly matched in the support frame 220, a plurality of the first small guide columns 222 are slidably matched with the movable oblique wedge block assembly, the middle part of the moving block 221 is connected and matched through a connecting rod 223 and a plurality of first springs 224, one end of the moving block 221 is connected and matched with the linkage plate 27, and the A plurality of rollers 225 are provided on the other end of the movable block 221, and the rollers 225 cooperate with the movable oblique wedge block assembly. The movable oblique wedge block assembly includes a first fixed block 226, an oblique wedge block element 227 and a contour block 228. The oblique wedge block element 227 passes through the first fixed block 226 and floats on the fixed end of the first fixed block 226 through a second spring 229. The contour block 228 is fixed on the fixed end of the first fixed block 226, and the contour block 228 cooperates with the product element. It can be seen that the support frame 220 supports and limits the first small guide column 222, the moving block 221 and the movable oblique wedge block assembly, the connecting rod 223 connects the moving block 221 and the first fixed block 226, the first fixed block 226 supports and limits the oblique wedge block element 227 and the contour block 228, the first small guide column 222 guides and limits the movement of the movable oblique wedge block assembly, the linkage plate 27 drives the moving block 221 to move left and right, and at the same time Because of the connection through the connecting rod 223, the inclined wedge element 227 will also move to the left, and the moving block 221 drives the roller 225 to move on the inclined wedge element 227. When the inclined wedge element 227 moves to the left to the limit, the moving block 221 still moves to the left, and the second spring 229 is squeezed. At the same time, the roller 225 passes the highest point on the inclined wedge element 227, which will push the inclined wedge element 227 inward, driving the contour block 228 to limit the product element.

[0020] like Fig. 9As shown, in this embodiment, the pressing block assembly module 23 includes a mobile base 230, a product limiting seat 231, a third spring 232 and a plurality of second small guide pillars 233. The mobile base 230 is provided with a protrusion, and the linkage plate 27 is provided with a push block. The push block cooperates with the protrusion to push the mobile base 230 to move forward. The mobile base 230 is provided with a probe element, and the probe element cooperates with the product element. It can be seen that the push block cooperates with the protrusion to push the mobile base 230 to move forward. The plurality of second small guide pillars 233 play a guiding and limiting role when the mobile base 230 moves forward. The third spring 232 plays a buffering role when the mobile base 230 moves forward to prevent excessive pressure from damaging parts or product elements.

[0021] like Fig.10 As shown, in this embodiment, the side pressure mold group 24 includes a floating plate 240, a support base 241 and a second slide rail 242. The support base 241 and the second slide rail 242 are both fixedly fitted on the large fixed block 20. The floating plate 240 and the second slide rail 242 are slidably fitted. A plurality of fourth springs 243 are arranged between the floating plate 240 and the support base 241. The two ends of the fourth spring 243 are respectively limitedly fitted with the floating plate 240 and the support base 241, and the floating plate 240 and the product component are limitedly fitted. It can be seen that the large fixed block 20 supports and fixes the support base 241 and the second slide rail 242. The floating plate 240 and the linkage rod 28 move to the right, so that the product components can be placed in the multi-action linkage module 2. The second slide rail 242 guides and limits the floating plate 240 when it moves left and right. The support base 241 supports and limits the fourth springs 243. The fourth springs 243 support and push the floating plate 240. When the floating plate 240 moves to the right, the fourth springs 243 absorb pressure. When the floating plate 240 releases the thrust, the fourth springs 243 drive the floating plate 240 to reset.

[0022] like Figure 7 and Figure 8As shown, in this embodiment, the contact end of the oblique wedge block element 227 is a trapezoidal structure with a high middle and low sides. It can be seen that the oblique wedge block element 227 is designed as a trapezoidal structure with a high middle and low sides, and the roller 225 on the moving block 221 plays a guiding role. When it moves to the middle part, it will push the oblique wedge block element 227 toward the product component, driving the contour block 228 to limit the product component. The roller 225 continues to move over the highest point on the oblique wedge block element 227, driving the Y-direction block module 22 to reset, thereby freeing up the test space.

[0023] In this embodiment, the working principle of the present invention is as follows: The first step, such as Figures 1 to 10 As shown, the linkage cylinder 21 remains in the started state, the product component is placed on the jig carrier 1, the Z-direction cylinder 10 is started, the active end of the Z-direction cylinder pushes the lifting module 12 to move upward, and lifts the flip module 11, and the flip module 11 squeezes and limits the product component limited on the jig carrier 1.

[0024] In the second step, the linkage cylinder 21 gradually moves to the left and returns to the initial state, the moving block 221 on the Y-axis stop block module 22 moves to the left, and the movable inclined wedge block assembly remains stationary. When the several rollers 225 on the moving block 221 cooperate with the highest point on the inclined wedge block element 227, the inclined wedge block element 227 limits the slave element inward.

[0025] In the third step, at the same time, the linkage cylinder 2 continues to move to the left, and the linkage rod 28 gradually stops limiting the floating plate 240. Under the action of the fourth springs 243, the floating plate 240 pushes the floating plate 240 to limit the product component. The push block and the protrusion are limited and matched, thereby driving the mobile base 230 to move toward the direction of the product component. The probe element on the mobile base 230 cooperates with the product component for testing.

[0026] In the fourth step, at the same time, the linkage cylinder 2 continues to move to the left, and the roller 225 passes over the highest point on the inclined wedge element 227, and drives the Y-axis block module 22 to reset through the connecting rod 223, thereby freeing up the test space.

[0027] Although the embodiments of the present invention are described with practical solutions, they do not constitute limitations on the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
