[0017] The thermal film packaging device of this application has at least the following beneficial effects:
[0018] The thermal sheet encapsulation equipment of this application uses a feeding component to transport the thermal sheet to the mounting platform component. The lifting drive component drives the mounting platform component and the thermal sheet to rise together, so that the thermal sheet is located below the printing stencil. The mesh pattern on the printing stencil is the shape of the encapsulation material (such as epoxy resin) to be printed.

[0043] like Figure 1 and Figure 2 As shown, this embodiment discloses a thermal sheet packaging device, including a first support platform 100, a feeding assembly 200, a mounting platform assembly 300, a lifting drive assembly 400, a second support platform 500, a printing stencil 600, a third support platform 700, and a printing assembly 800.
[0044] The first support platform 100 is supported on the ground or other foundation surface to provide support and installation foundation for various components.
[0045] like Figure 3 As shown, the feeding assembly 200 is disposed on the first support platform 100 and is used to convey the material (i.e., the thermal sheet 900) to the mounting platform assembly 300. The feeding assembly 200 includes a roller conveying mechanism 210 and a material picking mechanism 220; in this embodiment, along the first horizontal direction, the mounting platform assembly 300, the roller conveying mechanism 210, and the material picking mechanism 220 are sequentially disposed on the first support platform 100.
[0046] like Figure 3 As shown, the conveying direction of the roller conveying mechanism 210 is configured as the second horizontal direction. The thermal sheet 900 is disposed on the roller conveying mechanism 210. The rollers of the roller conveying mechanism 210 rotate and drive the thermal sheet 900 forward along the second horizontal direction. The roller conveying mechanism 210 in this embodiment refers to the prior art and will not be described in detail here.
[0047] like Figure 4As shown, the material handling mechanism 220 is disposed on the first support platform 100 along the first horizontal direction. The material handling mechanism 220 is located on one side of the roller conveyor mechanism 210 and the mounting platform assembly 300. The material handling mechanism 220 includes a mounting box 221, a sliding block 222, a first telescopic member 223, a second telescopic member 224, and a material handling fork 225. The mounting box 221 is disposed on the first support platform 100 and is located on one side of the roller conveyor mechanism 210 and the mounting platform assembly 300 along the first horizontal direction. The sliding block 222 is slidably connected to the mounting box 221 through a first guide shaft. The sliding block 222 can be positioned relative to the mounting box 221. The mounting box 221 slides in a first horizontal direction; the two ends of the first telescopic member 223 are respectively connected to the sliding block 222 and the inner wall of the mounting box 221, and the telescopic direction of the first telescopic member 223 is configured in the first horizontal direction; the second telescopic member 224 is disposed on the sliding block 222, and the telescopic direction of the second telescopic member 224 is configured in the vertical direction; both the first telescopic member 223 and the second telescopic member 224 include existing telescopic cylinders or electric push rods; the picking fork 225 is slidably connected to the sliding block 222, and the picking fork 225 can slide relative to the sliding block 222 in the vertical direction; the telescopic end of the second telescopic member 224 is connected to the picking fork 225. The picking fork 225 extends through the mounting box along the first horizontal direction to the outside of the mounting box 221, and the mounting box 221 is provided with a through hole to facilitate the passage of the picking fork 225, which allows the picking fork 225 to move in both the first horizontal direction and the vertical direction. The first horizontal direction and the second horizontal direction intersect perpendicularly in the horizontal plane.
[0048] The working principle of the feeding assembly 200 in this embodiment is as follows: The thermal sheet 900 is driven by the roller conveying mechanism 210 and moves along the second horizontal direction. When the thermal sheet 900 moves to one side of the picking mechanism 220 (one side along the first horizontal direction), the second telescopic member 224 drives the picking fork 225 to move downward. Then, the first telescopic member 223 drives the sliding block 222 and the picking fork 225 to move along the first horizontal direction, so that the picking fork 225 extends into the lower side of the thermal sheet 900. Then, the second telescopic member 224 drives the picking fork 225 and the thermal sheet 900 to lift upward and disengage from the roller conveying mechanism 210. Then, the first telescopic member 223 drives the sliding block 222, the picking fork 225 and the... The thermal sheet 900 retracts backward, and then the lifting drive assembly 400 drives the mounting platform assembly 300 to descend until the mounting platform 330 of the mounting platform assembly 300 is lower than the thermal sheet 900. The first telescopic member 223 drives the sliding block 222, the picking fork 225 and the thermal sheet 900 to extend towards the mounting platform assembly 300 in the first horizontal direction. The mounting platform 330 rises and lifts the thermal sheet 900 on the picking fork 225 to disengage from the picking fork 225. At the same time, the picking fork 225 moves away from the mounting platform 330 in the first horizontal direction under the drive of the first telescopic member 223 and the sliding block 222. At this time, the thermal sheet 900 has completed the transfer from the roller conveyor mechanism 210 to the mounting platform 330, and the loading is completed.
[0049] It should be noted that when the picking fork 225 picks up material, the picking fork 225 extends into the space between two adjacent rollers of the roller conveyor mechanism 210 along the first horizontal direction. Therefore, the picking fork 225 will not interfere with the roller conveyor mechanism 210. Similarly, the mounting platform assembly 300 (specifically the mounting platform 330) is provided with a relief groove that is recessed downward along the height direction. Therefore, when the mounting platform 330 rises and pushes the thermal sheet 900 upward, the mounting platform 330 will not interfere with the picking fork 225.
[0050] Please refer to it again. Figure 3 The mounting platform assembly 300 is slidably connected to the first support platform 100. The first support platform 100 is provided with a clearance channel 100a that runs through the height direction. When the mounting platform assembly 300 slides in the height direction, the clearance channel 100a can avoid the mounting platform assembly 300.
[0051] like Figure 5As shown, the mounting platform assembly 300 includes a sliding frame 310, a support structure 320, and a mounting platform 330. The sliding frame 310 is slidably connected to the first support platform 100 via a slide rail, and the sliding direction of the sliding frame 310 is configured in the height direction. The support structure 320 is disposed on the sliding frame 310, and the mounting platform 330 is disposed on the top of the support structure 320. The mounting platform 330 is provided with a negative pressure adsorption hole 330a, which is used to adsorb the thermistor 900 to ensure the stability of the thermistor 900 on the mounting platform 330. In this embodiment, the negative pressure adsorption hole 330a is connected to an external negative pressure source. The external negative pressure source creates negative pressure at the opening of the negative pressure adsorption hole 330a to tightly adsorb the thermistor 900.
[0052] The support structure 320 includes a first support 321, a second support 322, and a top platform 323, as detailed below:
[0053] like Figure 5 As shown, the lower end of the first bracket 321 is connected to the sliding frame 310, and the upper end of the first bracket 321 is slidably connected to the second bracket 322. The second bracket 322 can slide relative to the first bracket 321 in the second horizontal direction. A first threaded push rod 3211 is threadedly connected to the first bracket 321. The axial direction of the first threaded push rod 3211 is configured in the second horizontal direction. The end of the first threaded push rod 3211 can abut against the second bracket 322. When the first threaded push rod 3211 is threaded into the first bracket 321, the first threaded push rod 3211 abuts against the second bracket 322 and pushes the second bracket 322 to slide relative to the first bracket 321, thereby adjusting the position of the mounting platform 330 in the second horizontal direction.
[0054] Preferred, such as Figure 6 As shown, a first clamping plate 3212 is provided on the first bracket 321. The first clamping plate 3212 is provided with a first hole. The length direction of the first hole is configured as a second horizontal direction. A first clamping bolt 3213 passes through the first hole along the first horizontal direction and is threadedly connected to the second bracket 322. When the second bracket 322 is slidably adjusted, the first clamping bolt 3213 is screwed in, so that the first clamping bolt 3213 presses the first clamping plate 3212 onto the second bracket 322, thereby making the first bracket 321 and the second bracket 322 stably connected and preventing relative displacement between them in the second horizontal direction.
[0055] like Figure 5As shown, the upper end of the second bracket 322 is slidably connected to the top platform 323, and the top platform 323 can slide relative to the second bracket 322 in a first horizontal direction; a second threaded push rod 3221 is threadedly connected to the second bracket 322, the axial direction of the second threaded push rod 3221 is configured in the first horizontal direction, and the end of the second threaded push rod 3221 can abut against the top platform 323. When the second threaded push rod 3221 is threadedly screwed relative to the second bracket 322, the second threaded push rod 3221 abuts against the top platform 323 and pushes the top platform 323 to slide relative to the second bracket 322, thereby adjusting the position of the mounting platform 330 (the mounting platform 330 is set on the top platform 323) in the first horizontal direction;
[0056] like Figure 6 As shown, preferably, the second bracket 322 is provided with a second clamping plate 3222, and the second clamping plate 3222 is provided with a second hole. The length direction of the second hole is configured in the first horizontal direction. The second clamping bolt 3223 passes through the second hole along the second horizontal direction and is threadedly connected to the top platform 323. After the top platform 323 has slidably adjusted its position, the second clamping bolt 3223 is screwed in so that the second clamping bolt 3223 presses the second clamping plate 3222 onto the top platform 323, thereby making the second bracket 322 and the top platform 323 stably connected and preventing relative displacement between them in the first horizontal direction.
[0057] like Figure 5 As shown, the mounting platform 330 is provided with a rotating hole extending along the height direction. A rotating shaft 3231 is provided on the top platform 323. The axial direction of the rotating shaft 3231 is configured in the height direction. The rotating shaft 3231 passes through the rotating hole, and the mounting platform 330 can rotate around the rotating shaft 3231 as the rotation axis. The top platform 323 is threadedly connected to a third threaded push rod 3232. The axial direction of the third threaded push rod 3232 is configured in the first horizontal direction. The end of the third threaded push rod 3232 can abut against the mounting platform 330. When the third threaded push rod 3232 is screwed in, the end of the third threaded push rod 3232 can abut against the mounting platform 330 and push the mounting platform 330 to rotate around the rotating shaft 3231, thereby realizing the horizontal angle adjustment of the mounting platform 330.
[0058] The bracket structure 320 of this embodiment can adjust the position of the mounting platform 330 in the first horizontal direction and the second horizontal direction, and can also rotate the mounting platform 330 around the height direction to adjust the angle, thereby adapting to different printing position requirements.
[0059] like Figure 7As shown, in some preferred embodiments, the sliding connection between the first support 321 and the second support 322 is achieved by the first guide block 350 and the second guide block 360, and the sliding connection between the second support 322 and the top platform 323 is achieved by the third guide block 370 and the fourth guide block 380. Specifically, the first support 321 is provided with a first guide block 350 at its top, and the second support 322 is provided with a second guide block 360 at its lower end. The second guide block 360 is provided with a first guide groove, which is a through groove extending along the second horizontal direction. The first guide block 350 is slidably disposed in the first guide groove, and the size of the first guide block 350 matches the size of the first guide groove so that the first support 321 and the second support 322 can only slide relative to each other in the second horizontal direction. The second support 322 has a third guide block 370 at its top, and the top platform 323 has a fourth guide block 380 at its lower end. The fourth guide block 380 has a second guide groove, which is a through groove extending along the first horizontal direction. The third guide block 370 is slidably disposed within the second guide groove, and its size matches the second guide groove, so that the second support 322 and the top platform 323 can only slide relative to each other in the first horizontal direction. The cooperation of multiple guide blocks ensures the stability of the first support 321, the second support 322, and the top platform 323 when adjusting their positions.
[0060] Please refer to it again. Figure 5 In some preferred embodiments, a baffle mechanism 390 for limiting the thermal pad 900 in the second horizontal direction is provided on the top platform 323. There may be one or more baffle mechanisms 390; in this embodiment, two baffle mechanisms 390 are preferably provided on the top platform 323, respectively disposed on both sides of the top platform 323 along the second horizontal direction, for limiting the thermal pad 900 on both sides. The baffle mechanism 390 includes a baffle 391 and an elastic member 392; the baffle 391 is slidably connected to the top platform 323 along the second horizontal direction; one end of the elastic member 392 is connected to the baffle 391, and the other end of the elastic member 392 is connected to the top platform 323. The extension and retraction direction of the elastic member 392 is configured in the second horizontal direction, and the elastic member 392 includes a spring. The elastic element 392 has a tendency to pull the baffle 391 toward the thermal sheet 900, so that the inner side of the baffle 391 elastically presses the side of the thermal sheet 900, and the two baffles 391 on the left and right sides elastically press the two sides of the thermal sheet 900 respectively.
[0061] like Figure 8As shown, the lifting drive assembly 400 of this embodiment includes a first drive member 410, a first lead screw 420, and a first slider 430. The first drive member 410 is disposed at the lower end of the first support platform 100, and the first lead screw 420 is rotatably disposed on the first support platform 100. The axial direction of the first lead screw 420 is configured in the height direction. The output end of the first drive member 410 is connected to the first lead screw 420, and the first drive member 410 can drive the first lead screw 420 to rotate. In this embodiment, the output end of the first drive member 410 and the first lead screw 420 are connected through an existing pulley assembly. In addition, the first drive member 410 can also be connected to the first lead screw 420 through an existing chain drive assembly or coupling. The first slider 430 is threadedly engaged with the first lead screw 420. When the first lead screw 420 rotates, the first slider 430 can move in the height direction. The sliding frame 310 of the mounting platform assembly 300 is connected to the first slider 430.
[0062] In this embodiment, the first driving component 410 drives the mounting platform assembly 300 to move in the height direction. On the one hand, this facilitates the transfer of the thermal sheet 900 to the mounting platform 330 by the picking fork 225. On the other hand, it can drive the thermal sheet 900 to rise to the lower side of the printed stencil 600 for encapsulation.
[0063] like Figure 9 As shown, a second support platform 500 is disposed on the upper surface of the first support platform 100. The second support platform 500 has a square hole extending through it along its height. A printed stencil 600 is disposed within the square hole, and the stencil 600 has a mesh pattern. The mesh pattern is the shape of the encapsulation material (e.g., epoxy resin) to be printed, and the position of the mesh pattern corresponds to the position on the thermal sheet 900 to be encapsulated. The printed stencil 600 is located directly above the mounting platform 330.
[0064] like Figure 9 As shown, the third support platform 700 is disposed on the upper surface of the second support platform 500. The third support platform 700 is provided with a printing assembly 800. The printing assembly 800 includes a motion mechanism 810 for driving the squeegee mechanism 820 to move in the second horizontal direction and a squeegee mechanism 820 for scraping the encapsulation material from the printing stencil 600 onto the thermal sheet 900.
[0065] like Figure 9As shown, the motion mechanism 810 includes a second drive member 811, a second lead screw 812, and a second slider 813. The second drive member 811 is disposed on the third support platform 700, and the second lead screw 812 is rotatably disposed on the third support platform 700. The axial direction of the second lead screw 812 is configured in the second horizontal direction. The output end of the second drive member 811 is connected to the second lead screw 812, and the second drive member 811 can drive the second lead screw 812 to rotate. In this embodiment, the output end of the second drive member 811 is connected to the second lead screw 812 through a coupling. The second slider 813 is threadedly engaged with the second lead screw 812. When the second lead screw 812 rotates, the second slider 813 can drive the squeegee mechanism 820 to move in the second horizontal direction, thereby enabling the squeegee mechanism 820 to reciprocate in the second horizontal direction for printing and encapsulation.
[0066] like Figure 10 and Figure 11 As shown, the scraper mechanism 820 includes a movable plate 821, a vertical support 822, and two scraper units 823. The movable plate 821 is slidably connected to the third support platform 700 via a slide rail, so that the movable plate 821 can only slide in the second horizontal direction. The second slider 813 of the motion mechanism 810 is connected to the movable plate 821, and the movable plate 821 is driven to slide through the second slider 813. The vertical support 822 is disposed at the lower end of the movable plate 821 and is used to provide an installation and connection position for the scraper units 823.
[0067] like Figure 11 As shown, the scraper unit 823 includes a third driving member 8231, a third lead screw 8232, a third slider 8233, and a scraper plate 8234. The third driving member 8231 is mounted on the movable plate 821, and the third lead screw 8232 is rotatably mounted on the vertical support 822, with its axial direction aligned with the height. The output end of the third driving member 8231 is connected to the third lead screw 8232. In this embodiment, the output end of the third driving member 8231 is connected to the third lead screw 8232 via a coupling, allowing the third driving member 8231 to drive the third lead screw 8232 to rotate. The third slider 8233... 33 is slidably connected to the vertical support 822. The sliding direction of the third slider 8233 is configured in the height direction. The third slider 8233 is threadedly engaged with the third lead screw 8232. When the third lead screw 8232 rotates, the third slider 8233 slides in the height direction. The scraper plate 8234 is connected to the third slider 8233. The scraper plate 8234 can descend in height and contact the printed stencil 600. Driven by the motion mechanism 810, the scraper plate 8234 slides on the printed stencil 600, thereby scraping the encapsulation material from the printed stencil 600 onto the thermal sheet 900 to achieve the encapsulation of the thermal sheet 900.
[0068] like Figure 10As shown, in this embodiment, each of the two squeegee units 823 is provided with a squeegee plate 8234. The squeegee plates 8234 of the two squeegee units 823 are spaced apart in the second horizontal direction. The squeegee plate 8234 of the first squeegee unit has a first included angle θ with the printing stencil 600 (the printing stencil 600 is parallel to the horizontal plane), and the squeegee plate 8234 of the second squeegee unit has a second included angle β with the printing stencil 600. The first included angle and the second included angle are complementary angles. In some preferred embodiments, the range of the first included angle is 30 degrees to 60 degrees.
[0069] In this embodiment, the angle between the two squeegee plates 8234 and the printing stencil 600 is a complementary angle, and the two squeegee plates 8234 can alternately rise and fall under the drive of the third drive member 8231. Therefore, when the motion mechanism 810 drives the squeegee plates 8234 to move back and forth, the two squeegee plates 8234 can alternately print during the back and forth process, which greatly improves work efficiency.
[0070] In some preferred embodiments, the first drive member 410, the second drive member 811, and the third drive member 8231 are all preferably motors.
[0071] The working principle of the thermal chip packaging device in this embodiment is as follows:
[0072] First, the roller conveyor mechanism 210 conveys the thermal sheet 900 to one side of the picking mechanism 220. The picking mechanism 220 transfers the thermal sheet 900 on the picking fork 225 to the mounting platform 330 through the cooperation of the first telescopic member 223 and the second telescopic member 224.
[0073] Second, under the drive of the lifting drive assembly 400, the mounting platform 330 is raised to the lower side of the printing stencil 600.
[0074] Third, the first squeegee 8234 descends to contact the upper side of the printing stencil 600. The motion mechanism 810 drives the squeegee 8234 to slide on the printing stencil 600, scraping the encapsulation material onto the thermal sheet 900. Then, the first squeegee 8234 rises to a height that disengages from the printing stencil 600. The second squeegee 8234 descends to contact the upper side of the printing stencil 600. The motion mechanism 810 drives the squeegee 8234 to slide on the printing stencil 600. This process is repeated alternately, with the two squeegees 8234 printing alternately.
