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.

[0044] It should be understood that although the terms upper, middle, lower, top, one end, etc. appear in this article to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for the convenience of understanding, rather than for defining any directional or sequential limitations.

[0045] As Figures 1-11 shown, a PCB component dispensing and assembly structure includes a frame, on which there is a loading structure 1 for loading the mounting seat 4, and a dispensing and plug-in structure 2 for plugging the PCB component 5 and dispensing glue onto the mounting seat 4;

[0046] Specifically, the feeding structure 1 includes a feeding component 10 for conveying the mounting seat 4, and a grasping component 11 for moving the mounting seat 4 to the assembly area. The grasping component 11 includes a clamping and rotating unit 101 for clamping and rotating the mounting seat 4, and a cross-moving module 102 for driving the clamping and rotating unit 101 to move.

[0047] The dispensing and inserting structure 2 includes an assembly frame 20, and an inserting component 21 and a dispensing component 22 slidably arranged on the assembly frame 20. The inserting component 21 includes a clamping unit 201 for clamping the PCB component 5, and a driving module 202 for driving the clamping unit 201 to move towards the mounting seat 4. The dispensing component 22 includes a dispensing unit 203 and a lifting module 204 for driving the dispensing unit 203 to move up and down.

[0048] During the entire assembly process, first, the feeding component 10 moves the mounting seat 4 to a specified position. The clamping and rotating unit 101 of the grasping component 11 moves the mounting seat 4 to a specified assembly position under the action of the cross-moving module 102. Subsequently, the mounting seat 4 is acted on by the inserting component 21 and the dispensing component 22 respectively. The PCB component 5 is first inserted into the mounting seat 4 by the inserting component 21, and then the connection position between the mounting seat 4 and the PCB component 5 is dispensed with glue by the dispensing component 22, thereby realizing the automatic assembly of inserting and dispensing glue for the PCB component 5. Compared with manual assembly, the assembly efficiency is greatly improved, and the product assembly quality is higher.

[0049] As Figures 1 to 10 shown, for a further explanation of the structure of the mounting seat 4 in this embodiment, wherein the mounting seat 4 in this embodiment is actually a bakelite seat. A first mounting groove 41 and a second mounting groove 42 for placing the PCB component 5 are formed on the mounting seat 4, and the mounting seat 4 has a first position 43 for feeding along the conveying direction, a second position 44 for placing the PCB component 5 into the first mounting groove 41, and a third position 45 for placing the PCB component 5 into the second mounting groove 42.

[0050] During the assembly process of the mounting seat 4, the feeding component 10 linearly conveys the mounting seat 4 to the first position 43. Subsequently, the grasping component 11 grabs and moves the mounting seat 4 to the second position 44, inserts and dispenses glue into the first mounting groove 41 of the mounting seat 4. Then, the grasping component 11 grabs and moves the mounting seat 4 to the third position 45, inserts and dispenses glue into the first mounting groove 41 of the mounting seat 4, thereby realizing the installation and dispensing of the PCB component 5 in the two mounting grooves of the mounting seat 4, and greatly improving the assembly efficiency.

[0051] Wherein, when the mounting base 4 is in the second position 44, the first rotary clamping cylinder 112 rotates 90°, so that the first mounting groove 41 is arranged opposite to the plug-in component 21, and when the mounting base 4 is in the third position 45, the second rotary clamping cylinder 113 rotates 180°, so that the second mounting groove 42 is arranged opposite to the plug-in component 21.

[0052] The first rotary clamping cylinder 112 and the second rotary clamping cylinder 113 are used to drive the mounting base 4 to rotate, so that the first mounting groove 41 and the second mounting groove 42 are opposite to the PCB assembly 5, thereby realizing the plugging of the PCB assembly 5 into the first mounting groove 41 and the second mounting groove 42 of the mounting base 4 respectively.

[0053] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 11 As shown, for a further explanation of the turnover of the mounting base 4 in this embodiment, a transfer structure 3 is further provided on the frame. The transfer structure 3 includes a transfer plate 30 and a lifting module 31 for driving the transfer plate 30 to move up and down. A transfer groove 32 for placing and fixing the mounting base 4 is formed on the transfer plate 30, and the transfer groove 32 is located below the second position 44.

[0054] After the PCB assembly 5 and dispensing are completed in the first mounting groove 41 of the mounting base 4, the lifting module 31 drives the transfer plate 30 to rise, so that the mounting base 4 is placed in the transfer groove 32. Subsequently, the transverse movement module 102 drives the clamping and rotating unit 101 to move, and moves the mounting base 4 to the third position 45, so as to perform the insertion and dispensing of the PCB assembly 5 into the second mounting groove 42.

[0055] Specifically, the grasping component 11 further includes a transverse movement plate 111 arranged on the moving end of the transverse movement module 102. The clamping and rotating unit 101 is arranged on the transverse movement plate 111, and the clamping and rotating unit 101 includes a first rotary clamping cylinder 112 for clamping the mounting base 4 from the first position 43 to the second position 44, and a second rotary clamping cylinder 113 for clamping the mounting base 4 from the second position 44 to the third position 45.

[0056] Further, the transverse movement module 102 includes two interconnected sliding table cylinders, so as to drive the entire clamping and rotating unit 101 to move left and right, as well as forward and backward. First, the first rotating clamping cylinder 112 moves to the first position 43 under the action of the transverse movement module 102, clamps the mounting seat 4, and moves the mounting seat 4 from the first position 43 to the second position 44. By rotating the first rotating clamping cylinder 112, the first mounting groove 41 of the mounting seat 4 is arranged opposite to the PCB assembly 5. The plugging assembly 21 acts to insert the PCB assembly 5 into the first mounting groove 41, so as to realize the plugging of the PCB assembly 5 into the first mounting groove 41. After the plugging is completed, the dispensing assembly 22 dispenses glue into the first mounting groove 41. Subsequently, the transfer structure 3 rises to leave the mounting seat 4 on the transfer plate 30. The first rotating clamping cylinder 112 releases the mounting seat 4 and retreats. Then, the transverse movement module 102 drives the second rotating clamping cylinder 113 to clamp the mounting seat 4. The transfer plate 30 descends, and the second rotating clamping cylinder 113 moves the mounting seat 4 to the third position 45. By rotating the second rotating clamping cylinder 113, the second mounting groove 42 of the mounting seat 4 is arranged opposite to the PCB assembly 5, so as to realize the plugging of the PCB assembly 5 into the second mounting groove 42. After the plugging is completed, glue is dispensed into the second mounting groove 42, so as to realize the installation and glue dispensing of the PCB assembly 5 in the two mounting grooves on the mounting seat 4. And the above actions are repeated to synchronously assemble the two mounting seats 4, greatly improving the assembly efficiency.

A descending unit 214 is arranged on the moving plate 213, and a mounting plate 215 is arranged on the action end of the descending unit 214. The clamping unit 201 is arranged on the mounting plate 215.

[0059] During the plugging process of the PCB assembly 5, first, the descending unit 214 can drive the mounting plate 215 to descend so that the clamping unit 201 clamps the PCB assembly 5. Subsequently, the descending unit 214 raises the PCB assembly 5 to a height opposite to the mounting position of the mounting seat 4. Then, the driving module 202 drives the moving plate 213 to move towards the mounting seat 4, so that the PCB assembly 5 is inserted into the mounting seat 4, thus realizing the automatic plugging of the PCB assembly 5.

[0060] Preferably, a loading plate 211 is provided on the assembly frame 20, and a loading groove 212 for placing the PCB assembly 5 is formed on the loading plate 211. The PCB assembly 5 can be placed in the loading groove 212, thereby improving the feeding accuracy of the PCB assembly 5.

[0062] During the dispensing process, the telescopic cylinder 217 can drive the glue applying plate 216 to move along the assembly frame 20, so that the lifting module 204 moves to the top of the mounting seat 4, and the dispensing unit 203 is driven by the lifting module 204 to descend to a specified position for dispensing to ensure the dispensing quality.

[0063] Preferably, a slide rail assembly 71 is provided on the assembly frame 20, and the plugging assembly 21 and the dispensing assembly 22 are arranged on the slide rail assembly 71, which improves the smoothness of the sliding process of the plugging assembly 21 and the dispensing assembly 22.

[0064] As Figure 1 , Figure 2 , Figure 9 shown, in some other embodiments, a blanking assembly 61 is formed on the frame. The blanking assembly 61 includes a blanking conveyor belt 601 and a blanking plate 602 connecting the blanking conveyor belt 601 and the assembly area. The mounting seat 4 that has completed PCB plugging and dispensing will flow onto the blanking conveyor belt 601 along the blanking plate 602, thereby realizing automatic blanking to further improve the assembly efficiency.

[0065] As Figure 4 shown, in this embodiment, the feeding assembly 10 includes a circular vibrating bowl and a linear vibrating feeder. The mounting seat 4 in the circular vibrating bowl is input into the linear vibrating feeder through a conveying channel, and then the linear vibrating feeder conveys the mounting seat 4 to the first position 43.

[0066] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to this embodiment without creative contributions according to needs after reading this specification, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
