[0023] Figure 1 It is a cross-sectional view of the head device in an embodiment of the present invention. Detailed Embodiments

[0024] The present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining and illustrating the present invention, and are not used to limit the present invention.

[0025] In the present invention, unless otherwise stated, the orientation terms such as "upper, lower, left, right" generally refer to the upper, lower, left, and right in the drawings, and "inner, outer" refer to the inner and outer relative to the contour of the component.

[0026] It should be noted that the terms "first", "second", etc. in the claims, the description, and the drawings of the present application are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so as to be implemented in an order other than the embodiments described in the invention.

[0027] An embodiment of the present invention provides a reinforcement laminating device, including a material pasting system and a host system connected to the material pasting system. Among them, the material pasting system includes a head moving assembly and a head device connected to the head moving assembly.

[0028] The material pasting system is used to suck the material and move it above the electronic component, and then press it down to paste the material on the electronic component, while monitoring the pressure data and sending it to the host system. The host system is used to control the moving amplitude of the head device according to the real-time pressure data monitored by the material pasting system, so that the head device can paste the material more precisely, and at the same time, it can also avoid damaging the electronic component.

[0029] In the embodiments of the present invention, the head moving assembly can directly adopt the existing technology without design modification. To achieve the function of real-time monitoring of pressure data, the present invention improves the head device. Specifically, as Figure 1 shown, the head device of the embodiments of the present invention includes a connecting seat 1, a floating suction head assembly 27, and a guiding assembly 26, a pressure monitoring assembly 28, and a vacuum air path assembly 30 connecting the connecting seat 1 and the floating suction head assembly 27.

[0030] Among them, the connecting seat 1 is provided with a guiding hole 32 connecting the guiding assembly 26, a receiving chamber 19 for accommodating the pressure monitoring assembly 28, and an air outlet passage 31 connecting the top end of the vacuum air path assembly 30.

[0031] The floating suction head assembly 27 is spaced from the connecting seat 1 by a certain distance and can move axially along the guiding assembly 26; the floating suction head assembly 27 is provided with a fixing hole 17 connecting the bottom end of the guiding assembly 26, a receiving groove 18 for accommodating the pressure monitoring assembly 28, and a suction passage 29 connecting the bottom end of the vacuum air path assembly 30.

[0032] The bottom end of the guiding assembly 26 extends a certain distance out of the guiding hole 32, and the top end does not exceed the guiding hole 32;

[0033] The pressure monitoring assembly 28 includes an elastic component that can expand and contract along the moving direction of the floating suction head assembly 27, and a pressure sensor 10 connected to the elastic component.

[0034] Specifically, in this embodiment, the connecting seat 1 is integrally square and is connected to the head moving assembly on the patch reinforcement device, and can be connected by means of threads or the like. The guiding hole 32 is vertically arranged from the top surface to the bottom surface of the connecting seat 1, and the opening diameter of the top surface is larger than that of the bottom surface, so that the guiding sleeve 5 can be placed in the guiding hole 32. Of course, those skilled in the art can also set the guiding hole in other directions according to the actual situation, which will not affect the implementation of the present invention.

[0035] The receiving chamber 19 opens from the bottom surface of the connecting seat 1 and is axially aligned with the receiving groove 18 of the floating suction head assembly 27, so that the pressure monitoring assembly 28 can be placed in the receiving chamber 19 and the receiving groove 18.

[0036] The air outlet passage 31 includes an air outlet groove 24 opening on the top surface of the connecting seat 1, and an air delivery channel 25 provided inside the connecting seat 1 and communicating the air outlet groove 31 and the first air pipe joint 14.

[0037] Specifically, in this embodiment, there are four groups of vacuum air path assemblies 30, and vacuum extraction is carried out from the four directions of east, south, west, and north respectively. Of course, those skilled in the art can also set the vacuum air path assembly into other numbers and other directions according to the actual situation, which will not affect the implementation of the present invention.

[0038] The vacuum air path assembly 30 can transmit air flow, with one end connected to the air outlet path 31 and the other end connected to the air suction path 29. The vacuum air path assembly 30 includes a first tracheal connector 14 connected to the air outlet path 31, a second tracheal connector 13 connected to the air suction path 29, and a trachea 15 connecting the first tracheal connector 14 and the second tracheal connector 13.

[0039] Correspondingly, the air delivery channel 25 also has four directions, opening in four directions from the side wall of the air outlet groove 31 and extending through to the outer side wall of the connecting base 1. The first tracheal connector 14 is inserted into the opening of the air delivery channel 25 on the outer side wall of the connecting base 1. In the embodiment of the present invention, the trachea 15 is a flexible trachea with a certain elasticity. Therefore, when the floating suction head assembly 27 moves, the trachea 15 can bend along with the movement of the floating suction head assembly 27, thus not affecting the vacuum extraction function.

[0040] In the embodiment of the present invention, the air outlet groove 31 is arranged at the middle position on the top surface of the connecting base 1, and the accommodation chamber 19 opens from the middle position on the bottom surface and is axially aligned with the air outlet groove 31. Through holes are also provided on the side wall of the accommodation chamber 19, enabling the data line 16 of the pressure sensor 10 to pass through and be connected to the host.

[0041] Specifically, the pressure sensor 10 is adhesively fixed in the accommodation chamber 19 with solid glue. Below the pressure sensor 10 is an elastic component connecting to the accommodation groove 18. The elastic component can expand and contract along the moving direction of the floating suction head assembly 27, including a compression spring 12 fixed on the accommodation groove 18 and a compression spring guide post 11 connected between the pressure sensor 10 and the compression spring 12. Additionally, the pressure monitoring component can also be fixed in an inverted manner, with the pressure sensor 20 fixed on the accommodation groove 18 and the compression spring 12 fixed on the accommodation chamber 19.

[0042] The pressure sensor 10 is used to monitor the pressure in real time when attaching to the material. The pressure sensor 10 transmits the monitoring data to the host system of the patch reinforcement device through the pressure sensor data line 16. Here, the pressure sensor 10 only collects and transmits the pressure data, and the processing of the pressure data signal is completed by the host system. The host system controls the moving amplitude of the head moving assembly according to the real-time pressure data.

[0043] When the floating suction head assembly 27 moves downward to attach to the material, if it is subjected to a large pressure and the compression spring 11 deforms greatly, when the pressure sensor 10 senses a large pressure, the host system will adjust the downward movement of the floating suction head assembly 27 according to the specific pressure data, thereby effectively avoiding damage to electronic components and improving the attachment accuracy at the same time.

[0044] In addition, in the embodiment of the present invention, the guiding assembly 26 includes two groups, each group including two guiding assemblies 26 that are diagonally aligned, and at the same time, is spaced apart from the vacuum air path assembly 30. Correspondingly, the guiding holes 32 and the fixing holes 17 also include four. Through the positioning of these two groups of guiding assemblies 26, the floating suction head assembly 27 can be effectively prevented from rotating, ensuring that the floating suction head assembly 27 moves along the axis of the guiding assembly.

[0045] Specifically, the guiding assembly 26 includes a hollow guiding sleeve 5 placed in the guiding hole 32 and a guiding column assembly placed in the guiding sleeve 5; the top end of the guiding column assembly is placed in the guiding hole 32 and above the guiding sleeve 5, and the bottom end of the guiding column assembly extends out of the guiding hole 32 by a certain distance and is connected to the fixing hole 17. The guiding column assembly can move in the guiding hole 32 and does not exceed the top end of the guiding hole 32.

[0046] The guiding column assembly includes a stopper 3 placed in the guiding hole 32 and above the guiding sleeve 5, and a guiding column 4 with the top end connected to the stopper 3 and the bottom end connected to the suction head assembly 27 and placed in the guiding sleeve 5. The top end of the guiding column 4 is connected to the stopper 3 by a screw 2, and the bottom end is connected to the suction head assembly 27 by a screw 6. Of course, those skilled in the art can also use other methods for fixed connection according to the actual situation, which will not affect the implementation of the present utility model.

[0047] Specifically, the floating suction head assembly 27 includes a mounting plate 7 connecting the guiding assembly 26 and the vacuum air path assembly 30, and a suction plate 9 fixed to the bottom surface of the mounting plate 7.

[0048] Among them, the fixing hole 17 and the receiving groove 18 are both provided on the mounting plate 7. The fixing hole 17 is a threaded hole and is connected to the guiding column 4 by a screw. The receiving groove 18 is provided on the top surface of the mounting plate 7 for placing the compression spring 12 and is axially aligned with the receiving chamber 19.

[0049] The air suction passage 29 includes a ventilation groove 22 provided on the bottom surface of the mounting plate 7, an air vent 23 connecting the second air pipe joint 15 and the ventilation groove 22, and an air suction port provided on the suction plate 9 and communicating with the ventilation groove 22.

[0050] To enhance the suction force, in the embodiment of the present invention, the middle part of the lower surface of the suction plate 9 is in the shape of a convex platform protruding outward, and the air suction port penetrates the convex platform from top to bottom, including an air suction groove 21 grooved on the upper surface of the suction plate 9 and an air suction hole 20 opening from the upper opening of the air suction groove 21 and penetrating the lower surface of the suction plate. There are four air suction holes 20, which are evenly distributed. Of course, those skilled in the art can also set the number of air suction holes to other numbers according to the actual situation, which will not affect the implementation of the present invention. In this embodiment, the ventilation groove 22 is grooved in four directions of the vacuum air path assembly 30 and avoids the direction of the guiding assembly 26.

[0051] In addition, in this embodiment, the mounting plate 7 and the suction plate 9 are fixedly connected by screws 8, and the connecting seat 1 and the suction head moving assembly are also fixedly connected by screws. Of course, those skilled in the art can also use other methods for fixed connection according to actual situations, which will not affect the implementation of the present invention.

[0052] In summary, the present invention monitors the pressure data of the floating suction head assembly in real time and makes timely adjustments, so that the bonding head device and the electronic components always remain within an appropriate pressure range. Thus, adjustments can be made accordingly according to the size and height of different electronic components to achieve precise bonding and avoid damaging the electronic components.
