[0002] In the PCB manufacturing process, the surface mount technology (SMT) process is one of the key steps affecting product quality and yield, and is an essential process in the industry, with an application coverage of up to 99%. To ensure the accuracy and consistency of the SMT placement, existing manufacturers generally use fully automated or semi-automated equipment to complete the relevant operations.

[0003] However, traditional fully automated equipment requires a high initial investment, typically ranging from 1 million to 5 million yuan, which puts significant pressure on small and medium-sized manufacturing enterprises. Furthermore, such equipment has a complex structure, involving precision mechanical components and multiple control systems, making maintenance difficult and expensive. After long-term operation, the equipment requires regular maintenance and repairs, with annual maintenance costs typically accounting for 1.5% to 7% of the equipment investment cost, significantly increasing operating expenses. In addition, traditional automated equipment has poor flexibility and compatibility; most equipment can only adapt to products of fixed sizes or a limited number of specifications. When production tasks change, it often requires readjustment or replacement of tooling and fixtures, resulting in long turnaround times and further leading to low equipment utilization.

[0004] Therefore, current automated packaging and bonding equipment struggles to simultaneously meet the demands of rapid product changeovers and manufacturers' urgent need to reduce costs. The industry urgently requires a solution that is low-cost, easy to operate, simple to maintain, highly compatible, and capable of ensuring packaging quality, in order to enhance manufacturing competitiveness and effectively reduce production costs.

[0011] In some examples of this application, the translation drive also includes a handle; the handle is fixed to the base, the housing is provided with a guide groove, the extension direction of the guide groove is parallel to the axis of the guide rod, and the handle extends out of the housing through the guide groove, so that the handle can drive the base to move along the axis of the guide rod.

[0012] In some examples of this application, the inside of the flip plate is hollow to form an air extraction chamber, and the adsorption area of ​​the flip plate is provided with a plurality of mutually spaced through holes, which connect the air extraction chamber to the outside; the side of the flip plate opposite to the adsorption area is provided with an air extraction hole, which is used to connect to an external air extraction device to extract the gas in the air extraction chamber and generate negative pressure in the adsorption area.

[0024] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] This addresses the technical challenges of traditional fully automated packaging and bonding equipment, which is characterized by high costs and difficulty in meeting the rapid switching needs of different products.

[0028] Please see Figures 1 to 6 This embodiment provides a packaging device 100, which includes a housing 10, a flip plate 21, a first driving component 22, a roller 31, and a second driving component 32.

[0029] The housing 10 has a worktable 131 for holding the circuit board. The flip plate 21 is located above the worktable 131 and extends along the width of the worktable 131. The flip plate 21 is provided with an adsorption area 211 for fixing the encapsulation film. The first drive assembly 22 is connected to the flip plate 21 and is used to drive the flip plate 21 to flip back and forth between the loading position and the initial encapsulation position.

[0030] The roller 31 is located above the worktable 131; the second drive assembly 32 is disposed inside the housing 10 and is connected to the roller 31 in a transmission manner, so that the second drive assembly 32 can drive the roller 31 to move up and down in a direction perpendicular to the worktable 131, and to move horizontally along the length direction of the worktable 131.

[0031] When the first driving assembly 22 drives the flip plate 21 to rotate to the loading position, the adsorption area 211 is away from the worktable surface 131, and the encapsulation film can be adsorbed onto the adsorption area 211 and partially extend beyond the edge of the flip plate 21. When the first driving assembly 22 drives the flip plate 21 to rotate in the opposite direction to the initial encapsulation position, the adsorption area 211 of the flip plate 21 faces the worktable surface 131, and the side of the encapsulation film extending out of the flip plate 21 contacts the worktable surface 131; the second driving assembly 32 drives the roller shaft 31 to press down onto the worktable surface 131, and drives the roller shaft 31 to move along the length direction of the worktable surface 131, so as to gradually roll and adhere the encapsulation film on the flip plate 21 to the circuit board on the worktable surface 131.

[0032] Specifically, the top of the housing 10 forms a flat worktable 131 for holding the circuit board to be packaged. The worktable 131 can be adapted to the shape and size of the circuit board, and its surface maintains a high degree of flatness to ensure that the circuit board will not warp or move during the lamination process, thereby improving the lamination accuracy. The flip plate 21 is provided with an adsorption area 211, which can adsorb the encapsulation film to achieve positioning of the encapsulation film. The flip plate 21 can be flipped above the worktable 131 under the drive of the first drive component 22 to facilitate the loading and application of the encapsulation film. The roller 31 is arranged laterally above the worktable 131. The second drive component 32 includes two functional modules: lifting and horizontal movement, which can control the roller 31 to make precise downward pressure in the vertical direction and move at a uniform speed along the length of the worktable 131 during equipment operation.

[0033] During the work process, such as Figure 1 and Figure 2 As shown, before the coating operation begins, the flip plate 21 is driven by the first drive assembly 22 to rotate to the loading position. At this time, the adsorption area 211 of the flip plate 21 is away from the worktable surface 131 and is in an upward-facing state. The operator lays the pre-cut encapsulation film on the adsorption area 211 of the flip plate 21, leaving a portion of the encapsulation film edge extending beyond the edge of the flip plate 21.

[0034] After the encapsulation film is adsorbed, the first driving component 22 drives the flipping plate 21 to rotate counterclockwise to the initial encapsulation position, as shown below. Figure 3 As shown, the adsorption area 211 of the flip plate 21 faces downward and is directly opposite the worktable surface 131. At this time, there is a gap between the flip plate 21 and the worktable surface 131 for the roller shaft 31 to pass through. The encapsulation film extends out of the side of the flip plate 21 and contacts the worktable surface 131, thereby realizing the positioning and initial application of the encapsulation film at the starting end of the circuit board.

[0035] like Figure 3 and Figure 4 As shown, after the encapsulation film is in the initial bonding state, the second drive assembly 32 first drives the roller 31 to descend to the worktable 131. Then, the second drive assembly 32 continues to drive the roller 31 to move steadily to the right along the length of the worktable 131, so that the roller 31 presses the contact area between the encapsulation film and the circuit board under appropriate pressure. During the movement, the roller 31 rolls and bonds the encapsulation film from the starting end of the circuit board to the far end, so that the encapsulation film completely expels the trapped air during the rolling process and achieves uniform and firm bonding.

[0036] The packaging device 100 in this embodiment greatly simplifies the overall structure of the coating equipment. By integrating a roller pressing module with lifting and translation functions and a film-fixing module with flip-up film suction inside the same housing 10, a complete semi-automatic packaging film application process is realized. Its overall structure is compact and easy to operate, and it can be applied to the packaging of various circuit boards.

[0037] Please see Figures 3 to 5 In some embodiments, the housing 10 includes a base plate 11, a enclosure 12, and a support frame 13. The enclosure 12 surrounds the periphery of the base plate 11 to form a receiving cavity with a top opening. The support frame 13 is fixed to the base plate 11, and the top of the support frame 13 extends out of the opening of the receiving cavity so that the top surface of the supported frame 13 forms a worktable surface 131.

[0038] Specifically, the housing 10 can be composed of a base plate 11, enclosure 12, and support frame 13. The base plate 11 has an approximately rectangular flat plate structure and is used to provide basic support and load-bearing for the equipment. Enclosure 12 is vertically arranged around the base plate 11. The enclosure 12 is formed by multiple long strip-shaped side plates to form a box-like structure. The enclosure 12 can be connected to the base plate 11 by screw fastening or welding, so that the enclosure 12 is firmly installed around the perimeter of the base plate 11.

[0039] like Figure 5 As shown, the support frame 13 is located in the central area of ​​the base plate 11. The overall height of the support frame 13 is greater than the height of the enclosure 12, allowing the top of the support frame 13 to pass through the opening formed by the enclosure 12 and extend upward, so that the top surface of the support frame 13 is completely exposed outside the accommodating cavity. In some embodiments, the support frame 13 may include two vertically arranged upright plates 132, a horizontal plate 133 connected between the two upright plates 132, and a working plate 134 covering the horizontal plate 133. The bottoms of the two upright plates 132 are fixedly connected to the base plate 11 by screws or welding to maintain high stability; the two ends of the horizontal plate 133 are fixed to the two upright plates 132 to form a frame structure, and the working plate 134 covers the horizontal plate 133. The top surface of the working plate 134 facing away from the horizontal plate 133 forms the worktable surface 131 for placing circuit boards.

[0040] Please see Figure 2 and Figure 6 In some embodiments, the first drive assembly 22 includes a support plate 221, a rotary cylinder 222, and a rotating shaft 223. One end of the support plate 221 is fixedly connected to the housing 10, and the other end extends upward to protrude from the housing 10. The rotary cylinder 222 is disposed at the upper end of the support plate 221; one end of the rotating shaft 223 is connected to the rotary cylinder 222, and the other end is connected to the tilting plate 21, so that the tilting plate 21 is located above the worktable surface 131 and can rotate around the rotating shaft 223.

[0041] Specifically, the support plate 221 has a long, strip-shaped structure. Its bottom end is firmly fixed to the base plate 11 of the housing 10 by screws or welding, and its other end extends vertically upward, with its free end protruding above the housing 10. The height of the support plate 221 is set higher than the worktable surface 131, so that its upper end can provide a space for the flipping plate 21, ensuring that the flipping plate 21 will not interfere with the housing 10 during the flipping action. The cylinder body of the rotary cylinder 222 is fixed to the top of the support plate 221 by bolts. One end of the rotating shaft 223 is fixedly connected to the output end of the rotary cylinder 222. The rotating shaft 223 extends in the transverse direction, and its axis is basically parallel to the width direction of the worktable surface 131. The other end of the rotating shaft 223 is fixedly connected to the flipping plate 21, so that the flipping plate 21 can be flipped around the rotating shaft 223 under the drive of the rotary cylinder 222. In this embodiment, the rotary cylinder 222 can achieve an angle adjustment structure within the range of 0° to 160° to meet the angle requirements of the flipping plate 21 from the loading position to the initial packaging position.

[0042] During the loading phase of the equipment operation, the rotary cylinder 222 controls the rotating shaft 223 to flip the flip plate 21 to the loading position. In this position, the adsorption area 211 of the flip plate 21 faces away from the worktable surface 131, facilitating manual application of the encapsulation film to the surface of the adsorption area 211 of the flip plate 21. After loading is completed, the rotary cylinder 222 reverses its movement, causing the rotating shaft 223 to rotate the flip plate 21 back to the initial encapsulation position. In this position, the adsorption surface of the flip plate 21 faces the worktable surface 131 and is slightly inclined, forming an acute angle with the worktable surface 131, so that the protruding part of the encapsulation film contacts the circuit board first. This posture ensures that when the roller shaft 31 presses down and begins to move horizontally, it gradually rolls and applies the encapsulation film from the front end to the back, avoiding large-area contact at once that could cause bubbles or wrinkles.

[0043] Of course, in some other embodiments, the rotation of the flip plate 21 can also be controlled by a stepper motor.

[0044] Please see Figures 1 to 3 In some embodiments, the interior of the flip plate 21 is hollow, forming a suction chamber. The adsorption area 211 of the flip plate 21 has multiple spaced-apart through holes that connect the suction chamber to the outside. A suction hole 212 is provided on the side of the flip plate 21 facing away from the adsorption area 211. The suction hole 212 is used to connect to an external suction device to extract gas from the suction chamber, thereby creating a negative pressure in the adsorption area 211.

[0045] Specifically, the flip plate 21 adopts a hollow structure, forming a closed suction chamber inside. One side of the flip plate 21 is provided with an adsorption area 211, within which multiple evenly spaced through holes are machined. These through holes penetrate the adsorption surface of the flip plate 21 and communicate with the internal suction chamber. The diameter of the through holes can be selected from 0.2mm to 1mm depending on the material and thickness of the encapsulation film, ensuring sufficient negative pressure during suction without leaving obvious indentations on the surface of the encapsulation film.

[0046] A suction port 212 is provided on the side of the flip plate 21 facing away from the adsorption area 211. This suction port 212 is connected to an external suction device via a flexible hose. The suction device can be a vacuum pump, a micro air pump, or a vacuum equalization system. During operation, air is continuously pumped into the suction chamber, creating a negative pressure inside the suction chamber. This negative pressure acts on the adsorption area 211 through the through-hole, thereby firmly adsorbing the encapsulation film onto the surface of the adsorption area 211.

[0047] During the loading process, after the flipping plate 21 is flipped to the loading position, the operator places the sheet of encapsulation film on the surface of the adsorption area 211. After the vacuum equipment is started, the negative pressure formed in the adsorption area 211 will quickly adsorb the encapsulation film, making the encapsulation film tightly and flat on the adsorption area 211. At the same time, due to the uniform distribution of through holes, the negative pressure covers the entire adsorption area 211, thereby ensuring that the encapsulation film does not produce local bulging or suspension. The front end of the encapsulation film extends outward appropriately before adsorption, so that it naturally exceeds the edge of the flipping plate 21, providing a reserved starting bonding position for subsequent roll bonding.

[0048] The flip plate 21 uses negative pressure to adsorb the encapsulation film, making the film replacement process quick and simple, which can significantly improve the production cycle of the equipment. In addition, negative pressure adsorption will not cause mechanical damage to the encapsulation film, making it especially suitable for thin, soft, or easily scratched encapsulation film materials.

[0049] Of course, in some other embodiments, an electrostatic module can be arranged inside the flip plate 21 to adsorb the encapsulation film onto the plate surface, or the edge of the film material can be auxiliaryly fixed by a retractable clamping frame to meet the fixing requirements of the film material.

[0050] Please see Figure 4 and Figure 5 In some embodiments, the second drive assembly 32 includes a lifting drive 321 and a translation drive 322. The lifting drive 321 is mounted on the translation drive 322 and is connected to the roller 31, for driving the roller 31 to move up and down in a direction perpendicular to the worktable surface 131. The translation drive 322 is installed inside the housing 10 and connected to the lifting drive 321, for driving the lifting drive 321 and the roller 31 thereon to move horizontally along the length direction of the worktable surface 131.

[0051] During the encapsulation process, after the flip plate 21 has placed the encapsulation film in the initial encapsulation position, the lifting drive 321 first activates, pressing the roller 31 down onto the worktable 131. Subsequently, the translation drive 322 activates, moving the lifting drive 321 forward as a whole, causing the roller 31 to roll along the length of the circuit board, thus gradually applying the encapsulation film to the circuit board surface. After application, the lifting drive 321 lifts the roller 31 to facilitate removal by the operator, and the translation drive 322 returns the roller 31 to the starting position, preparing for the next encapsulation cycle.

[0052] Please see Figure 4 and Figure 5 In some embodiments, the lifting drive 321 includes a base 3211, a telescopic cylinder 3212, and a fixed plate 3213. The end of the roller 31 is rotatably connected to the fixed plate 3213, and the base 3211 is disposed within the housing 10. One end of the telescopic cylinder 3212 is fixedly connected to the base 3211, and the other end is connected to the fixed plate 3213, enabling the telescopic cylinder 3212 to drive the fixed plate 3213 and the roller 31 thereon to move vertically.

[0053] Specifically, there are two fixing plates 3213, and bearing seats are provided on the opposite sides of the two fixing plates 3213. The left and right ends of the roller shaft 31 are respectively inserted into the bearing seats and can rotate freely within the bearing seats. The base 3211 is fixedly installed inside the housing 10, and its length corresponds to the axial length of the roller shaft 31, so that it can stably support the telescopic cylinder 3212 and the fixing plates 3213.

[0054] The telescopic cylinder 3212 may include a cylinder body and a piston rod. The cylinder body can be fixed to both ends of the upper surface of the base 3211, and the piston rod extends upward, with its upper end connected to the fixed plate 3213. By controlling the air source pressure, the extension or retraction of the piston rod can be controlled, thereby driving the fixed plate 3213 to move up and down in the vertical direction, so that the roller 31 can descend from the standby position away from the worktable 131 to the pressing position close to the worktable 131.

[0055] Of course, in some other embodiments, the telescopic cylinder 3212 can be replaced with a lead screw motor assembly, which drives the lead screw to rotate and thus raise and lower the fixed plate 3213.

[0056] Please see Figure 4 and Figure 5In some embodiments, the translation drive 322 includes a guide rail 3221, a slider 3222, and a translation cylinder (not shown in the figure). The guide rail 3221 is disposed within the housing 10 and extends along the length of the worktable surface 131. The slider 3222 is slidably mounted on the guide rail 3221, and the side of the slider 3222 facing away from the guide rail 3221 is fixedly connected to the base 3211. The translation cylinder is disposed on the guide rail 3221 and connected to the slider 3222 to drive the slider 3222 to reciprocate along the guide rail 3221, thereby driving the lifting drive 321 and its roller 31 to translate along the length of the worktable surface 131.

[0057] Specifically, the guide rail 3221 is fixed to the base plate 11 of the housing 10, and the translation cylinder is arranged inside the guide rail 3221. The cylinder body of the translation cylinder is fixed to one end of the guide rail 3221; the free end of the piston rod of the translation cylinder is fixedly connected to the slider 3222. When the piston rod of the translation cylinder extends, it pushes the slider 3222 to move along the guide rail 3221 to one end; when the piston rod retracts, the slider 3222 moves in the opposite direction. This causes the slider 3222 to perform linear reciprocating motion on the guide rail 3221, thereby driving the base 3211 fixedly connected to the slider 3222, the telescopic cylinder 3212 on the base 3211, the fixed plate 3213 on the telescopic cylinder 3212, and the roller 31 rotatably connected between the fixed plates 3213 to move synchronously.

[0058] For example, when the packaging device 100 is in such a state Figure 3 In the initial encapsulation position shown, the telescopic cylinder 3212 retracts first, causing the roller 31 to descend and rest against the surface of the encapsulation film laid on the worktable 131. Subsequently, the translation cylinder extends, driving the slider 3222 to move to the right along the guide rail 3221. The slider 3222 is fixedly connected to the base 3211, therefore the base 3211, the telescopic cylinder 3212 on the base 3211, the fixing plate 3213, and the roller 31 supported by both ends of the fixing plate 3213 all translate synchronously. During the translation process, the roller 31 continuously rolls and presses the encapsulation film while rotating, ensuring that the encapsulation film is evenly and smoothly adhered to the circuit board surface.

[0059] After the translation stroke is completed, the telescopic cylinder 3212 extends, lifting the roller 31 away from the worktable 131 to facilitate the replacement of the next circuit board to be packaged. Simultaneously with the lifting of the roller 31, the rotary cylinder 222 drives the tilting plate 21 to rotate clockwise to... Figure 1 The loading position shown allows the adsorption area 211 of the flip plate 21 to face away from the worktable surface 131, enabling the user to re-lay the encapsulation film. After the film is loaded, the translation cylinder retracts, causing the slider 3222 to drive the lifting drive 321 and roller 31 back to the initial encapsulation position along the guide rail 3221, thus preparing for the next encapsulation cycle.

[0060] Please see Figure 4 and Figure 5 In some embodiments, the translation drive 322 further includes a plurality of guide rods 3223. The guide rods 3223 are disposed within the housing 10, and the axis of the guide rods 3223 is parallel to the extension direction of the guide rail 3221; the base 3211 passes through the guide rods 3223 and is capable of reciprocating along the guide rods 3223.

[0061] Specifically, two guide rods 3223 are provided, with both ends of the two guide rods 3223 connected to the upright plate 132 of the support frame 13. The axial direction of the guide rods 3223 is parallel to the extension direction of the guide rail 3221. The base 3211 of the lifting drive component 321 is machined to form a cylindrical through hole extending through its thickness direction. Each through hole corresponds to one guide rod 3223, allowing the base 3211 to be fitted onto the outside of the guide rod 3223. A suitable sliding clearance is maintained between the inner diameter of the through hole and the outer diameter of the guide rod 3223 to ensure that the base 3211 has sufficient guiding accuracy and moderate resistance when moving along the guide rod 3223.

[0062] During the translation process, the base 3211 is driven to slide by the slider 3222 on the guide rail 3221, while the guide rod 3223 provides additional linear support for the base 3211, so that the base 3211 and its lifting drive 321 and roller 31 maintain stable linear motion in the translation direction.

[0063] Please see Figure 1 In some embodiments, the translation drive 322 further includes a handle 3224, which is fixed to the base 3211. The housing 10 has a guide groove 121, the extension direction of which is parallel to the axis of the guide rod 3223. The handle 3224 extends out of the housing 10 through the guide groove 121. The handle 3224 can move along the extension direction of the guide groove 121 to drive the base 3211 to move along the axis of the guide rod 3223, thereby driving the roller 31 to translate along the length of the worktable surface 131.

[0064] Specifically, the translation drive 322 is equipped with a manual handle 3224 for easy operation. This manual handle 3224 is mainly used as a backup operation during equipment debugging, maintenance, and power outages. It can also serve as a manual auxiliary positioning mechanism, allowing the roller 31 to be quickly adjusted between different positions, thereby providing greater operational flexibility and redundancy for the entire machine.

[0065] The manual handle 3224 is securely fixed to the side wall of the base 3211 of the lifting drive 321. Its shape can be a long, narrow grip for easy holding by the operator. A narrow guide groove 121 is provided on the front side wall of the enclosure 12 corresponding to the position of the handle 3224. This guide groove 121 extends along the same length direction as the worktable 131 and is parallel to the axis of the guide rod 3223 inside the housing 10. The length of the guide groove 121 matches the maximum allowable translational stroke of the roller 31 on the worktable. When the operator manually pushes or pulls the handle 3224, the drive base 3211 slides on the guide rod 3223, and the slider 3222 passively slides on the guide rail 3221, causing the entire lifting drive 321 and its roller 31 to move synchronously along the length direction of the worktable 131.

[0066] The manual handle 3224 in this embodiment provides operational redundancy. Operators can use the manual handle 3224 to make fine adjustments to the initial position, pressure initiation position, or pressure termination position of the roller shaft 31 on the worktable 131, making the coating process more precise and improving the flexibility and adaptability of production.

[0067] Please see Figure 1 and Figure 3 In some embodiments, a control button 40 is provided on each side of the enclosure 12. The two control buttons 40 are used to simultaneously control the start and stop of the packaging device 100.

[0068] Specifically, when the operator needs to start the equipment to perform the packaging cycle, both control buttons 40 must be pressed simultaneously. The control system will only drive the equipment to perform automatic packaging processes such as rolling, flipping, and translation after detecting that both control buttons 40 have been triggered. With the above settings, the operator must remove both hands from the work area and press the buttons on both sides simultaneously before starting the equipment, thereby effectively avoiding the risk of accidental start-up due to single-handed operation and significantly improving the safety of equipment use.

[0069] In summary, this embodiment provides a packaging device 100, which includes a housing 10, a flip plate 21, a first driving assembly 22, a roller 31, and a second driving assembly 32. The flip plate 21 can flexibly flip between a feeding position and an initial packaging position under the drive of the first driving assembly 22. During feeding, the adsorption area 211 faces away from the worktable surface 131, allowing the packaging film to be quickly adsorbed and positioned without obstruction. During packaging, the flip plate 21 resets and lays the film material onto the area to be packaged. Under the control of the second driving assembly 32, the roller 31 can not only move vertically to control pressure but also translate along the length of the worktable surface 131, achieving segmented roller pressing and attachment of the packaging film. The adsorption area 211 of the flip plate 21 enables the packaging film to be quickly adsorbed for rapid positioning, thereby fixing various packaging films. The roller 31, under the control of the second driving assembly 32, can move vertically to control pressure, allowing the packaging film material to be evenly spread under controlled pressure and stable movement without producing bubbles, wrinkles, or shifts.

[0070] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
