[0001] The utility model is applied to the field of functional testing of electronic products, and particularly relates to a rotary vertical pressing mechanism. Background Art
[0002] During the production process of electronic products, functional testing is required. Currently, after the PCB board is assembled and soldered, the PCB board to be tested needs to be installed on a fixture, and workers use pins to contact the contact points of the functional areas on the PCB board to be tested. However, this operation is very laborious and time-consuming, and due to reasons such as the shaking of workers' hands, a high retest rate and unqualified rate are caused. In this context, if a rotary vertical pressing mechanism with a simple structure, rapid operation, and time-saving operation can be designed, the above problems can be well solved. Summary of the Invention
[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a rotary vertical pressing mechanism with a simple structure, rapid operation, and time-saving operation.
[0004] The technical solution adopted by the utility model is as follows: The utility model includes a carrier plate module, a flip cover module, and a vertical pressing module. One side of the flip cover module is rotationally matched with the carrier plate module through a rotating pin, and the other side of the flip cover module is in limit cooperation with the carrier plate module. The vertical pressing module is fixedly matched on the flip cover module. An eccentric cam assembly and a probe assembly are arranged on the vertical pressing module, and the eccentric cam assembly pushes the probe assembly to cooperate with the product to be tested on the carrier plate module. It can be seen that a rotating pin is arranged between one side of the flip cover module and the carrier plate module, so that the flip cover module can rotate. Since the vertical pressing module is fixed on the flip cover module, when the flip cover module rotates, it drives the vertical pressing module. When the other side of the flip cover module is in limit cooperation with the carrier plate module, under the push of the eccentric cam assembly, the probe assembly contacts and cooperates with the product to be tested.
[0005] Further, the carrier plate module further includes a carrier plate element, a buckle convex block, a plurality of guide sleeves, and a plurality of support plates. The buckle convex block is fixedly matched on the side of the carrier plate element away from the rotating pin. A cross-shaped groove is arranged on the carrier plate element, and the product to be tested is in limit cooperation in the cross-shaped groove. A plurality of the guide sleeves are fixedly matched with the upper surface of the carrier plate element, and a plurality of the support plates are fixedly matched with both sides of the lower surface of the carrier plate element.
[0006] Further, the vertical pressing module further includes a mounting base, linear bearings, and a plurality of guide posts. The mounting base is in limiting cooperation with the flip cover module. Holes are provided at the four top corners of the inner cavity of the mounting base. The linear bearings are in limiting cooperation within the holes. The linear bearings are in sliding cooperation with the guide posts. The eccentric cam assembly is in floating cooperation with the mounting base through a first spring. The probe assembly is in floating cooperation with the mounting base through a plurality of second springs.
[0007] Further, the flip cover module further includes a flip cover base, a buffer block, a flip cover working plate, a buckle base, and a limiting block. The flip cover base is fixedly cooperated with the carrier element. The buffer block is arranged between the flip cover base and the flip cover working plate. Both sides of the buffer block are respectively in cooperation with the flip cover base and the flip cover working plate. The flip cover working plate is rotationally cooperated with the flip cover base through the rotary pin. The buckle base and the limiting block are both arranged on the side of the flip cover working plate away from the rotary pin. A rotary buckle for limiting cooperation with the buckle convex block is provided on the buckle base. The limiting block is fixedly cooperated with the lower surface of the flip cover working plate.

[0016] As Figures 1 to 5 shown, in this embodiment, the utility model includes a carrier board module 1, a flip cover module 2 and a vertical pressing module 3. One side of the flip cover module 2 is rotationally matched with the carrier board module 1 through a rotating pin 20, and the other side of the flip cover module 2 is in limit cooperation with the carrier board module 1. The vertical pressing module 3 is fixedly matched on the flip cover module 2. An eccentric cam assembly 30 and a probe assembly 31 are arranged on the vertical pressing module 3. The eccentric cam assembly 30 pushes the probe assembly 31 to cooperate with a product to be tested 10 on the carrier board module 1. It can be seen that a rotating pin 20 is arranged between one side of the flip cover module 2 and the carrier board module 1, so that the flip cover module 2 can rotate. Since the vertical pressing module 3 is fixed on the flip cover module 2, the flip cover module 2 drives the vertical pressing module 3 while rotating. When the other side of the flip cover module 2 is in limit cooperation with the carrier board module 1, under the push of the eccentric cam assembly 30, the probe assembly 31 is in contact and cooperation with the product to be tested 10.
[0017] As Figure 3 shown, in this embodiment, the carrier board module 1 further includes a carrier board element 11, a snap convex block 12, a plurality of guide sleeves 13 and a plurality of support plates 14. The snap convex block 12 is fixedly matched on the side of the carrier board element 11 away from the rotating pin 20. A cross-shaped groove is arranged on the carrier board element 11. The product to be tested 10 is in limit cooperation in the cross-shaped groove. A plurality of the guide sleeves 13 are fixedly matched with the upper surface of the carrier board element 11, and a plurality of the support plates 14 are fixedly matched with both sides of the lower surface of the carrier board element 11. It can be seen that the support plates 14 play a supporting role for the carrier board element 11. The snap convex block 12 is arranged on the side of the carrier board element 11 away from the rotating pin 20 to realize limit cooperation with the flip cover module 2. A cross-shaped groove is arranged on the carrier board element 11 to facilitate the limit cooperation of the product to be tested 10 on the carrier board element 11. A plurality of the guide sleeves 13 are arranged near the cross-shaped groove to facilitate the vertical pressing module 3 to perform contact testing on the product to be tested 10. The guide sleeves 13 play a role in guiding the vertical pressing module 3 to perform a pressing movement.
[0018] As Figure 5As shown, in this embodiment, the vertical pressing module 3 further includes a mounting base 32, a linear bearing 33, and a plurality of guide posts 34. The mounting base 32 is in limit fit with the flip cover module 2. Holes are provided at the four top corners of the inner cavity of the mounting base 32. The linear bearing 33 is in limit fit in the holes. The linear bearing 33 is in sliding fit with the guide posts 34. The eccentric cam assembly 30 is in floating fit with the mounting base 32 through a first spring 35. The probe assembly 31 is in floating fit with the mounting base 32 through a plurality of second springs 36. Thus, both sides of the mounting base 32 are in floating fit with the eccentric cam assembly 30 and the probe assembly 31 through springs respectively, which can partially absorb the vertically downward force and reduce the appearance damage of the vertical pressing module 3 during the contact with the product under test 10. The cooperation of the linear bearing 33 and the guide posts 34 realizes the guiding function of the mounting base 32 on the eccentric cam assembly 30 and the probe assembly 31.
[0019] As Figure 4 shown, in this embodiment, the flip cover module 2 further includes a flip cover base 21, a buffer block 22, a flip cover working plate 23, a buckle base 24, and a limit block 25. The flip cover base 21 is fixedly fitted on the carrier element 11. The buffer block 22 is arranged between the flip cover base 21 and the flip cover working plate 23. Both sides of the buffer block 22 are respectively in fit with the flip cover base 21 and the flip cover working plate 23. The flip cover working plate 23 is rotationally fitted with the flip cover base 21 through the rotating pin 20. The buckle base 24 and the limit block 25 are both arranged on the side of the flip cover working plate 23 away from the rotating pin 20. A rotating buckle 26 for limit fit with the buckle protrusion 12 is provided on the buckle base 24. The limit block 25 is fixedly fitted with the lower surface of the flip cover working plate 23. Thus, when the flip cover working plate 23 is rotationally fitted with the flip cover base 21, the buffer block can absorb the flipping force generated by the flip cover module 2. The buckle base 24 and the limit block 25 are arranged on the side of the flip cover working plate 23 away from the rotating pin 20. The rotating buckle 26 is in limit fit with the buckle protrusion 12. The limit block 25 ensures that the flip cover working plate 23 is parallel to the surface of the carrier working plate 11 when it rotates to the horizontal position.
[0020] As Figure 4 shown, in this embodiment, a plurality of torsion springs 27 rotatably fitted with the rotating pin 20 are provided on the rotating pin 20. A plurality of mounting holes for limit fit with the torsion springs 27 are provided on the carrier element 11. Thus, a plurality of the torsion springs 27 are stuck in the mounting holes of the carrier element 11, and by releasing the torsion springs 27, the flip cover module 2 can be quickly rotated, saving operation time.
[0021] As Figure 5 shown, in this embodiment, the eccentric cam assembly 30 includes an eccentric cam element 300, an upper cover plate 301, and a floating plate 302. The floating plate 302 is connected to the first spring 35. The eccentric cam element 300 is rotatably engaged with the upper cover plate 301 through a rotating shaft 303, and the lower surface of the upper cover plate 301 is fixedly engaged with the floating plate 302. Thus, when the eccentric cam element 300 is toggled by an operator, the eccentric cam element 300 rotates along the rotating shaft 303, pushing the upper cover plate 301 and the floating plate 302 to move. Since the floating plate 302 is connected to the mounting base 32, it also indirectly pushes the mounting base 32 and the probe assembly 31 to move.
[0022] As Figure 5 shown, in this embodiment, the probe assembly 31 includes an adapter plate 310, a needle body mounting block 311, a plurality of probe elements 312, and a plurality of positioning pins 313. The adapter plate 310 is connected to the second spring 36. The adapter plate 310 is fixedly engaged with the needle body mounting block 311. A plurality of the probe elements 312 and a plurality of the positioning pins 313 are uniformly arranged on the needle body mounting block 311. Thus, a plurality of the probe elements 312 and a plurality of the positioning pins 313 are fixed on the needle body mounting block 311. When the probe assembly 31 moves downward, it drives the needle body element 310 to be in contact and cooperation with the product under test 10. The positioning pins 313 are in limit cooperation with the guide sleeve 13. The positioning pins 313 play a role in guiding the needle body element 310. When the contact between the needle body element 310 and the product under test 10 is completed, part of the applied force can be absorbed by the second spring 36 to protect the appearance of the product under test 10.
[0023] In this embodiment, the working principle of the present invention is as follows:
[0024] As Figures 1 to 5 shown, the operator places the product under test 10 into the cross-shaped groove, manually covers the flip cover module 2, and the flip buckle 26 is in limit cooperation with the buckle protrusion 12. When the flip cover working plate 23 rotates to a horizontal position and is parallel to the surface of the carrier working plate 11, rotate the eccentric cam assembly 30 to make the probe assembly 31 move downward to contact the product under test 10 and start the test. When the test is completed, open the eccentric cam assembly 30, the probe assembly 31 automatically resets, then open the flip buckle 26, the flip cover module 2 automatically flips, and take out the completed test product 10, and so on in a cycle.
[0025] Although embodiments of the present utility model are described with actual solutions, they do not constitute a limitation to the meaning of the present utility model. For those skilled in the art, modifications to its implementation solutions according to this specification and combinations with other solutions are obvious.
