[0035] In actual use, the PCBA to be assembled is placed in the PCBA feeding mechanism 2, the cover plate to be assembled is placed in the cover plate feeding mechanism 3, and the foam to be assembled is wound in the foam feeding mechanism 4. The turnover positioning mechanism 5 first ensures that the front face is upward, the material taking and pressing mechanism 6 takes out the PCBA from the PCBA feeding mechanism 2 and places it on the front face of the turnover positioning mechanism 5 so that the turnover positioning mechanism 5 fixes the PCBA, then the material taking and pressing mechanism 6 takes out the foam from the foam feeding mechanism 4 and adheres it to the front face of the PCBA, then the turnover positioning mechanism 5 turns over the PCBA by 180°, and then the material taking and pressing mechanism 6 takes out the cover plate from the cover plate feeding mechanism 3 and assembles it with the back face of the PCBA.

[0036] In the above design, only one turnover positioning mechanism 5 is needed to fix the PCBA, so that the structure of the whole device is more compact, and the volume of the whole device is more easily reduced.

[0037] Specifically, as shown in the drawings, Figure 3 As shown, the turnover positioning mechanism 5 comprises a first seat 51 arranged on the rack 1, a first linear guide rail 52 and a first linear module 53 arranged on the first seat 51 along the X-axis direction, a first sliding seat 54 slidingly arranged on the first linear guide rail 52 and driven by the first linear module 53, a supporting plate 55 rotationally arranged on the first sliding seat 54 with the X-axis as the rotation shaft, a first motor 56 arranged on the first sliding seat 54 and used to drive the supporting plate 55 to rotate, a first suction cup 57 arranged on the front face of the supporting plate 55, a first air cylinder 59 vertically arranged on the first sliding seat 54, and a lifting plate 58 arranged on the output end of the first air cylinder 59, and the supporting plate 55 is provided with a through hole 500 used to avoid the material taking and pressing mechanism 6.

[0038] In actual use, the front surface of the supporting plate 55 is horizontally upward, the material taking and pressing mechanism 6 places the PCBA on the first suction cup 57 to fix the PCBA, then the material taking and pressing mechanism 6 attaches the foam on the front surface of the PCBA, then the first motor 56 drives the supporting plate 55 to rotate 180°, so that the first suction cup 57 synchronously drives the PCBA to rotate 180°, and then the material taking and pressing mechanism 6 assembles the cover plate on the back surface of the PCBA by penetrating through the through hole 500. Then the first motor 56 drives the supporting plate 55 to reset, and the material taking and pressing mechanism 6 takes out the finished product to realize discharging.

[0039] In the above design, the structure design and specific implementation of the turnover positioning mechanism 5 can not only facilitate the fixation of the PCBA when assembling the foam, but also facilitate the positioning of the PCBA when assembling the cover plate, realize the simplification of the device structure, and reduce the volume of the equipment.

[0040] Specifically, as shown in Figure 4 and Figure 5 , the cover plate feeding mechanism 3 comprises a second seat 31 arranged on the rack 1, a second linear guide rail 32 arranged on the second seat 31 along the X-axis direction, a second sliding frame 33 slidingly arranged on the second linear guide rail 32, a second suction disc 34 arranged on the second sliding frame 33, a second handle 35 arranged on the second sliding frame 33, a second clamping piece A 36 arranged at the front end of the second seat 31, a second clamping piece B 37 arranged at the rear end of the second seat 31, a second protruding part A 38 arranged on the second sliding frame 33 for cooperation with the second clamping piece A 36, and a second protruding part B 39 for cooperation with the second clamping piece B 37.

[0041] In actual use, the second suction disc 34 full of cover plates is placed on the second sliding frame 33, the second sliding frame 33 is driven to slide along the second linear guide rail 32 by pushing the second handle 35, so that the second clamping piece A 36 is clamped with the second protruding part A 38 to realize the elastic fixation of the second sliding frame 33 and the second suction disc 34. When all the cover plates on the second suction disc 34 are transferred, the second handle 35 is pulled to make the second clamping piece A 36 disengage from the second protruding part A 38, and then the second sliding frame 33 slides along the second linear guide rail 32 to realize the cooperation of the second clamping piece B 37 and the second protruding part B 39.

[0042] In the above design, the structure design and specific implementation of the cover plate feeding mechanism 3 facilitate the fixation and movement of the second sliding frame 33, and facilitate the placement of the second suction disc 34.

[0044] It should be noted that the opposite direction can be derived from the opening direction of the groove, and the opening direction of the groove of the second clamping piece A 36 corresponds to that of the second clamping piece B 37.

[0045] In actual use, taking the cooperation between the second clamping piece A 36 and the second protruding part A 38 as an example, the clamping part 382 extends into the groove, the clamping part 382 extrudes the elastic plunger 362 twice during the extension process, and after the clamping part 382 completely enters the groove, the elastic plunger 362 extends into the arc-shaped slot after resetting, thereby achieving the clamping of the clamping part 382 and fixing the second protruding part A 38. When the second sliding frame 33 is pulled to make the second protruding part A 38 and the second clamping piece A 36 disengage, the protruding body 381 moves along the second sliding frame 33 synchronously, the sidewall of the arc-shaped slot extrudes the elastic plunger 362 to realize the contraction of the elastic plunger 362, and then the protruding part removes the groove.

[0046] In the above design, the structure design and specific implementation of the second clamping piece A 36 and the second clamping piece B 37 facilitate the fixing and disengagement of the second clamping piece A 36 and the second clamping piece B 37, thereby facilitating the sliding and fixing of the second sliding frame 33 along the second linear guide rail 32.

[0048] In actual use, the third tray 27 full of PCBA is placed on the third positioning plate 26, and the third sliding plate 24 is driven by the third linear module 22 to move to the side of the material taking and pressing mechanism 6, so that the third positioning plate 26 and the third tray 27 move synchronously. When the third tray 27 needs to be re-stacked, the third sliding plate 24 is driven by the third linear module 22 to move to the outside of the rack 1, and when the third linear module 22 stops driving, the third protruding portion A is separated from the third clamping piece A by pulling the third sliding plate 24, and then the third protruding portion B is matched with the third clamping piece B 28 by moving the third sliding plate 24 along the third linear guide rail B 25 to realize the fixation of the third sliding plate 24, and then a new batch of PCBA is placed in the third tray 27.

[0054] In actual use, when it is necessary to absorb foam or attach foam to PCBA, the rotating platform A6173 drives the No. 5 connecting frame A6174 to rotate, causing the No. 5 suction nozzle A6177 to rotate to a predetermined angle. Then, the No. 5 cylinder A6171 drives the No. 5 lifting plate to move down. When the No. 5 suction nozzle A6177 absorbs foam or lowers the foam, the stroke of the No. 5 cylinder A6171 is not completed, causing the No. 5 spring A6176 to compress. When the No. 5 pressure sensor A6178 detects that the pressure has reached the predetermined position, the PLC control system controls the No. 5 cylinder A6171 to end its stroke, and the No. 5 spring A6176 stops deforming.

[0055] In the above design, the structural design and specific implementation of the foam adsorption component 617 facilitate the sensing of the pressure on the foam by the No. 5 pressure sensor during foam adsorption and assembly, and the buffering of the foam by the No. 5 spring A6176.

[0056] Specifically: such as Figure 12 As shown, the PCBA adsorption assembly 616 includes a cylinder B6161 vertically mounted on a mounting bracket B612, a lifting plate B6162 mounted on the output end of the cylinder B6161, a rotating platform B6163 mounted on the lifting plate B6162, a connecting frame B6164 mounted on the output end of the rotating platform B6163, a lifting seat B6165 slidably mounted on the connecting frame B6164, a spring B6166 between the lifting seat B6165 and the connecting frame B6164, a suction nozzle B6167 at the lower end of the lifting seat B6165, and a pressure sensor B6168 mounted on the connecting frame B6164 for sensing the pressure of the lifting seat B6165.

[0057] In actual use, when PCBA needs to be adsorbed or placed on the carrier plate 55, the No. 5 connecting frame B6164 is rotated by rotating the platform B6163 to drive the No. 5 suction nozzle B6167 to rotate to a predetermined angle, and then the No. 5 lifting plate B6162 is driven downward by the No. 5 cylinder B6161. When the No. 5 suction nozzle B6167 adsorbs or releases the PCBA, the No. 5 cylinder A6171 stroke is not completed, so that the No. 5 spring B6166 is compressed. When the No. 5 pressure sensor B6168 detects that the pressure reaches a predetermined position, the No. 5 cylinder B6161 stroke is controlled to end by the PLC control system, and the No. 5 spring B6166 stops deforming.

[0058] In the above design, the structure design and specific implementation of the PCBA adsorption assembly 616 can effectively realize the adsorption and buffering of the PCBA, and the pressure feedback of the PCBA placed on the carrier plate 55 is realized by the No. 5 pressure sensor B6168, so as to prevent excessive extrusion of the PCBA.

[0059] Specifically, as shown in Figure 13 The cover plate adsorption assembly 613 includes a No. 5 cylinder C6131 vertically arranged on the No. 5 mounting frame A611, a No. 5 lifting plate C6132 arranged at the output end of the No. 5 cylinder C6131, a rotating platform C6133 arranged on the No. 5 lifting plate C6132, a No. 5 connecting frame C6134 arranged at the output end of the rotating platform C6133, a No. 5 lifting seat C6135 slidingly arranged on the No. 5 connecting frame, a No. 5 spring C6136 arranged between the No. 5 lifting seat C6135 and the No. 5 connecting frame C6134, a No. 5 suction nozzle C6137 arranged at the lower end of the No. 5 lifting seat C6135, a No. 5 pressure sensor C6138 arranged on the No. 5 connecting frame C6134 for sensing the pressure of the No. 5 lifting seat C6135, a No. 5 cylinder D6139 vertically arranged on the No. 5 lifting seat C6135, and a material supporting frame 6130 arranged at the output end of the No. 5 cylinder D6139. The material supporting frame 6130 is provided with a No. 5 hole for avoiding the No. 5 suction nozzle C6137.

[0060] In actual use, when the cover plate needs to be adsorbed or assembled on the PCBA, the fifth connecting frame C6134 is driven to rotate by rotating the platform C6133, so that the fifth suction nozzle C6137 is rotated to a predetermined angle, and then the fifth lifting plate C6132 is driven to move downward by the fifth cylinder C6131. When the fifth suction nozzle C6137 adsorbs or releases the cover plate, the stroke of the fifth cylinder C6131 is not completed, so that the fifth spring C6136 is compressed. When the fifth pressure sensor C6138 detects that the pressure reaches a predetermined position, the stroke of the fifth cylinder C6131 is controlled to end by the PLC control system, and the fifth spring C6136 stops deforming. Subsequently, the fifth cylinder C6131 is reset, the material supporting frame 6130 is driven to move downward by the fifth cylinder D6139, and the fifth suction nozzle C6137 is ensured to be separated from the cover plate.

[0061] In the above design, the structure design and specific implementation of the cover plate adsorption assembly 613 facilitate the adsorption of the cover plate, and the pressure feedback during the assembly of the cover plate can be realized by the fifth pressure sensor C6138, so as to ensure the assembly precision of the cover plate and the PCBA.

[0062] The second embodiment provided in the present application is a method for assembling foam and a cover plate on a PCBA, which adopts the PCBA foam and cover plate assembling device. The turnover positioning mechanism 5 is first ensured to face upward, the material taking and pressing mechanism 6 takes the PCBA from the PCBA feeding mechanism 2 and places it on the front surface of the turnover positioning mechanism 5, so that the turnover positioning mechanism 5 fixes the PCBA. Then, the material taking and pressing mechanism 6 takes the foam from the foam feeding mechanism 4 and adheres it to the front surface of the PCBA. Then, the turnover positioning mechanism 5 turns the PCBA by 180°, and then the material taking and pressing mechanism 6 takes the cover plate from the cover plate feeding mechanism 3 and assembles it with the back surface of the PCBA.

[0063] In the above design, the PCBA front surface adheres the foam, and the PCBA back surface assembles the cover plate without switching tooling, so that the whole process is more smooth and efficient.

[0064] It should be understood that the above description is only a specific embodiment of the present application and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
