Description

Technical Field

[0001] The utility model relates to the field of automation equipment, in particular to a pressing mechanism for vision alignment. Background Art

[0002] When manufacturing electronic components such as Hall current sensors, it is necessary to package raw material main boards, face covers and other components. The specific assembly process is as described in the patent number "CN113671224A". First, the outer shell is fed, then laser marking is carried out on the outer shell. After marking, PCB feeding, assembly and welding are carried out. After welding, laser trimming and UV coating are carried out. Finally, capping treatment is carried out. During the capping treatment process, it is necessary to manually pick up the face cover and cover it on the main board, so that the pins of the face cover correspond to the busbars of the main board. Finally, the face cover and the main board are pressed by a pressing device, so that the pins of the face cover are inserted into the busbars of the main board.

[0003] Since the sizes of the main board and the face cover are small, and the number of pins on the face cover is large, when manually aligning the busbar and the pins before the pressing operation, visual observation is prone to positional deviation, resulting in a small number of pins not being accurately inserted into the corresponding busbars after pressing, and the assembly accuracy of capping is low, affecting the use performance and service life of the product. Therefore, it is urgent to solve. Summary of the Utility Model

[0004] In order to avoid and overcome the technical problems existing in the prior art, the utility model provides a pressing mechanism for vision alignment. The utility model greatly improves the pressing and assembly accuracy of the product main board and the face cover.

[0005] To achieve the above object, the utility model provides the following technical solutions:

[0006] A pressing mechanism for vision alignment includes a first alignment platform for fixing the face cover and a pressing seat for clamping the main board and driving the main board to produce a vertically downward pressing action on the base. There are two groups of vision stations arranged on the base. One group of vision stations observes the pin positions of the face cover from top to bottom, and the other group of vision stations observes the busbar positions of the main board from bottom to top; the first alignment platform includes a displacement adjustment mechanism for driving the face cover to produce horizontal displacement and rotation actions, and the movement trajectory of the displacement adjustment mechanism has an intersection with the projection position of the main board in the vertical direction.

[0007] As a further solution of the utility model: the displacement adjustment mechanism includes a first X-axis guide rail fixed on the base tabletop, a Y-axis guide rail is installed on the slide of the first X-axis guide rail, and a rotation adjustment seat for fixing the face cover is fixed on the slide of the Y-axis guide rail.

[0008] As a further solution of the present utility model: a second alignment platform is further provided on the base tabletop. The second alignment platform includes a second X-axis guide rail arranged parallel to the first X-axis guide rail. A positioning arm for conveying the main board is fixed on the sliding seat of the second X-axis guide rail. The sliding trajectory of the positioning arm intersects with the projection position of the pressing seat along the vertical direction, and the positioning arm is staggered in height from the displacement adjustment mechanism of the first alignment platform.

[0009] As a further solution of the present utility model: the pressing seat includes a manipulator that clamps the main board, and the manipulator is driven by a hydraulic mechanism arranged along the vertical direction to move up and down.

[0010] As a further solution of the present utility model: an inspection slot is opened on the base. One set of vision workstations is installed in the inspection slot and corresponds to the manipulator of the pressing seat along the vertical direction. The vision workstation is staggered in height from the displacement adjustment mechanism of the first alignment platform.

[0011] As a further solution of the present utility model: the vision workstation includes an annular light source and a camera coaxially arranged at the center of the light source.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. The present utility model observes the bus bar of the main board and the pin positions on the face cover through two sets of vision workstations respectively. Thus, the deflection angle of the face cover is first adjusted by the displacement adjustment mechanism to correspond to the deflection angle of the main board. Then, through horizontal displacement, after the face cover is moved directly below the main board, pressing the main board can complete the pressing and fixing of the face cover to the main board, greatly improving the pressing and assembly accuracy of the product main board and face cover.

[0014] 2. The present utility model can accurately adjust the horizontal position of the face cover through the cooperation of multiple guide rails and the rotary adjustment seat, so that it can correspond to the vertical position of the main board before pressing, effectively improving the assembly accuracy; through the suspended transportation of the positioning arm, the position interference between the main board transportation process and the displacement adjustment mechanism is avoided, improving the transportation efficiency of the main board.

[0015] 3. The present utility model realizes the rapid clamping and pressing and fixing of the main board through the cooperation of the manipulator and the hydraulic mechanism, with high efficiency and accuracy; the setting of the double vision workstations can observe the positions of the main board and the face cover respectively, so that the positions can be pre-adjusted after comparison to ensure the accurate pressing position; the staggered arrangement of the double vision workstations will not cause position interference with the displacement adjustment mechanism and the second alignment platform.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figure 1 , in the embodiment of the present invention, a pressing mechanism for vision alignment includes a base 1, on which a first alignment platform 2 and a second alignment platform 3 are installed. The first alignment platform 2 is used to receive and convey the face cover 22. The first alignment platform 2 includes two groups of first X-axis guide rails arranged in parallel. The Y-axis guide rail is fixed on the sliders of the two first X-axis guide rails. A rotary adjustment base 21 is installed on the slider of the Y-axis guide rail. The face cover 22 is snap-fitted and fixed in the positioning groove of the rotary adjustment base 21 and is coaxially arranged with the rotary adjustment base 21. The pins of the face cover 22 are arranged upward. The first X-axis guide rail, the Y-axis guide rail, and the rotary adjustment base 21 cooperate to form a displacement adjustment mechanism, thereby adjusting the horizontal position and deflection angle of the face cover 22.

[0025] The second alignment platform 3 includes a second X-axis guide rail, which is arranged in parallel with the first X-axis guide rail. A positioning arm 31 perpendicular to the second X-axis guide rail is suspended on the slider of the second X-axis guide rail. The positioning arm 31 receives and conveys the main board 32. Preferably, a positioning groove is provided at the arm end of the positioning arm 31 to snap-fix and position the main board 32. The busbar of the main board 32 is arranged downward. The arrangement height of the positioning arm 31 is staggered from the arrangement height of the rotary adjustment base 21 to avoid stroke interference.

[0026] A pressing seat 4 for pressing the face cover 22 and the main board 32 is installed on the base 1. The pressing seat 4 includes a manipulator 41 and a hydraulic mechanism for driving the manipulator 41 to perform a lifting and pressing action in the vertical direction. After the positioning arm 31 conveys the main board 32 to directly below the manipulator 41, the hydraulic mechanism drives the manipulator 41 to descend and performs a clamping and fixing action on the main board 32. After clamping the main board 32, the positioning arm 31 resets to the initial position and waits to convey the next main board 32.

[0027] An inspection slot 11 is formed between the two first X-axis guide rails. Two groups of vision stations 5 are arranged on the base 1. One group of vision stations 5 is arranged side by side with the pressing seat 4 and is used to observe the pin positions of the face cover 22 from top to bottom. The other group of vision stations 5 is installed in the inspection slot 11, directly below the clamping end of the manipulator 41, and is used to observe the busbar positions of the main board 32 from bottom to top. Since the vision station 5 is built into the inspection slot 11, there will be no position interference with the movement of the displacement adjustment mechanism.

[0028] Both vision stations 5 include an annular light source 52 and a camera 51 coaxially arranged at the light source 52. By observing the busbar of the main board 32 and the pin positions on the face cover 22 through the two groups of vision stations 5 respectively, first adjust the deflection angle of the face cover 22 through the displacement adjustment mechanism to make it correspond to the deflection angle of the main board 32, and then through horizontal displacement, move the face cover 22 to directly below the main board 32, and then press down the main board 32 to complete the pressing and fixing of the face cover 22 and the main board 32.
