[0003] For PCBs of different sizes, the existing technical solution mainly uses a mezzanine-based cavity method to fix PCBs of different sizes. In this solution, the mezzanine can generally only control 3 to 5 cavities. Therefore, when dealing with PCBs of various sizes, it is necessary to use shielding materials such as plastic film to cover the areas not covered by the PCB to prevent the air intake holes not covered by the PCB from being connected to the atmosphere and thus failing to form a stable vacuum value.

[0004] However, using plastic film or other covering materials for lamination requires manual operation, which is inefficient and prone to errors, affecting production efficiency and product quality. Furthermore, since applying plastic film or other covering materials requires certain skills and experience, this method also presents certain difficulties and limitations in practice.

[0036] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] like Figures 1 to 5 As shown, one embodiment of the present invention provides a board material adsorption device 100, which includes an adsorption platform 110 and a film coating mechanism 120.

[0040] Specifically, such as Figure 4 As shown, the adsorption platform 110 is used to place the sheet material. The surface of the adsorption platform 110 has multiple suction holes 111, and the suction holes 111 covered by the sheet material can adsorb the sheet material; as shown... Figure 1 and Figure 3 As shown, the coating mechanism 120 includes a drive assembly, a film winding assembly, and a shielding film 121. The drive assembly is mounted on the adsorption platform 110, and the film winding assembly is rotatably mounted on the drive assembly. One end of the shielding film 121 is fixed to one side of the adsorption platform 110 along the first direction (X direction), and the other end of the shielding film 121 is wound around the film winding assembly. The drive assembly is used to drive the film winding assembly to move along the first direction (X direction) so that the shielding film 121 covers the air suction holes 111 that are not covered by the sheet metal in the first direction (X direction).

[0041] When it is necessary to adsorb and fix the sheet material onto the adsorption platform 110, the suction holes 111 covered by the sheet material adsorb the sheet material. At the same time, the driving component drives the film winding component to move along the first direction. The shielding film 121 covers the suction holes 111 that are not covered by the sheet material in the first direction (X direction) to prevent the suction holes 111 that are not covered by the sheet material from being connected to the atmosphere. This makes the adsorption platform form a stable vacuum value, improves the adsorption reliability, and achieves a good adsorption effect.

[0042] The board adsorption device 100 provided in one embodiment of this utility model can automatically open or close the adsorption holes by performing a coating operation through a coating mechanism 120. Compared with manual operation, it improves the coating efficiency, production efficiency and adsorption stability.

[0043] The sheet metal adsorption device 100 provided in one embodiment of this utility model is specifically as follows: Figures 2 to 4 As shown, the film roll assembly includes a first roller 122 and two support seats 123. The two support seats 123 are slidably mounted on both sides of the adsorption platform 110 along the second direction (Y direction) in a first direction (X direction). The two ends of the first roller 122 are rotatably mounted on the two support seats 123 in a corresponding manner. The shielding film 121 is wound around the first roller 122. When the drive assembly drives the two support seats 123 to slide synchronously along the first direction (X direction) on both sides of the adsorption platform 110 along the second direction (Y direction) for film coating, the first roller 122 rotates relative to the two support seats 123 so that the shielding film 121 wound on the first roller 122 covers the air suction holes 111 in the first direction (X direction) that are not covered by the sheet material.

[0044] Furthermore, such as Figures 3 to 4 As shown, the film winding assembly also includes an elastic element 124. One end of the elastic element 124 is connected to the first roller 122, and the other end is connected to the support base 123. The elastic element 124 can provide elastic force, allowing the first roller 122 to rewind the shielding film 121. In this embodiment, the elastic element 124 is a spring. When the driving assembly drives the two support bases 123 to slide synchronously along the first direction (X direction) on both sides of the adsorption platform 110 in the second direction (Y direction) for film coating, the first roller 122 rotates relative to the two support bases 123 under the action of the shielding film 121, and compresses the spring, so that the spring accumulates a restoring force. When the driving assembly drives the two support bases 123 to slide synchronously in the opposite direction along the first direction (X direction) on both sides of the adsorption platform 110 for film winding, the spring drives the first roller 122 to rotate in the opposite direction relative to the two support bases 123, so that the shielding film 121 shrinks and winds onto the first roller 122.

[0045] In this embodiment, as Figures 3 to 4 As shown, the support base 123 has a mounting hole, the end of the first roller 122 is installed in the mounting hole, and one end of the spring is connected to the end of the first roller 122, while the other end of the spring is connected to the inner wall of the mounting hole.

[0046] The sheet metal adsorption device 100 provided in one embodiment of this utility model, further, as... Figure 2As shown, the film roll assembly also includes a second roller 125. The two ends of the second roller 125 are rotatably mounted on two support seats 123, and the second roller 125 and the first roller 122 are spaced apart and parallel. One end of the shielding film 121 passes around the second roller 125 and is fixed to the adsorption platform 110. The second roller 125 is used to press the shielding film 121 firmly against the adsorption platform 110. When the drive assembly drives the two support seats 123 to slide synchronously along the first direction (X direction) on both sides of the adsorption platform 110 along the second direction (Y direction) for film coating, the second roller 125 presses the shielding film 121 firmly against the adsorption platform 110, thereby improving the coating quality. In this embodiment, the diameter of the first roller 122 is larger than the diameter of the second roller 125. The first roller 122 is located above the second roller 125. The first roller 122 is used to wind the shielding film 121, and the second roller 125 is used to press the shielding film 121 against the air intake hole 111.

[0047] In one specific embodiment, such as Figures 2 to 4 As shown, the adsorption platform 110 is provided with guide members 112 on both sides along the second direction. The guide members 112 extend along the first direction (X direction), and two support seats 123 are slidably installed on the two guide members 112 in a corresponding manner along the first direction. In this embodiment, the guide member 112 is a guide rail, and the support seat 123 is provided with a guide groove, which slides in cooperation with the guide rail. When the driving component drives the two support seats 123 to slide synchronously along the first direction (X direction) on both sides of the adsorption platform 110 along the second direction (Y direction), the sliding cooperation between the guide groove and the guide rail ensures that the support seat 123 always slides along the first direction (X direction), preventing the support seat 123 from moving vertically relative to the adsorption platform 110. This ensures that the second roller 125 presses the shielding film 121 tightly against the adsorption platform 110, improving the film coating quality.

[0048] The sheet metal adsorption device 100 provided in one embodiment of this utility model is specifically as follows: Figures 2 to 4 As shown, the drive assembly includes a drive unit and two synchronous belt units 126. The two synchronous belt units 126 are mounted one-to-one on both sides of the adsorption platform 110 along the second direction (Y direction). Two support seats 123 are connected one-to-one to the two synchronous belt units 126. The drive unit is used to synchronously drive the two synchronous belt units 126 to move along the first direction (X direction). When the drive assembly drives the two support seats 123 to slide synchronously along the first direction (X direction) on both sides of the adsorption platform 110 along the second direction (Y direction), the drive unit is used to synchronously drive the two synchronous belt units 126 to move along the first direction (X direction).

[0049] In one specific embodiment, such as Figures 2 to 4As shown, the synchronous belt 126 unit includes a synchronous belt 126 and two synchronous pulleys 127. The two synchronous pulleys 127 are installed one-to-one on both sides of the adsorption platform 110 along the first direction. The synchronous belt 126 is installed on the two synchronous pulleys 127 and can drive the support base 123 to move. The support base 123 is provided with a clamping member 128, which clamps and fixes the synchronous belt 126. The drive unit includes a rotary drive member 129 and a rotating shaft 130. The rotary drive member 129 is installed on the adsorption platform 110, and the rotating shaft 130 is rotatably installed on the adsorption platform 110. The rotary drive member 129 is used to drive the rotating shaft 130 to rotate, and the rotating shaft 130 can drive the two synchronous belt 126 units to move synchronously. One synchronous pulley 127 of each of the two synchronous belt 126 units is installed one-to-one on both ends of the rotating shaft 130. In this embodiment, the rotary drive member 129 is a drive motor.

[0050] When the drive assembly drives the two support seats 123 to slide synchronously on both sides of the adsorption platform 110 along the second direction (Y direction) and along the first direction (X direction), the drive motor drives the rotating shaft 130 to rotate. The rotating shaft 130 can synchronously drive one of the synchronous pulleys 127 of the two synchronous belt units to rotate synchronously. The synchronous pulley 127 drives the synchronous belt 126 to rotate, and the synchronous belt 126 drives the support seat 123 to slide synchronously along the first direction (X direction).

[0051] The sheet metal adsorption device 100 provided in one embodiment of this utility model, further, as... Figures 5 to 6 As shown, the sheet metal adsorption device 100 also includes an adjustment mechanism 140, which is used to adjust the number of suction holes 111 that can communicate with the vacuum device in the second direction.

[0052] Specifically, one end of the adjustment mechanism 140 is connected to the adsorption platform 110, and the other end is connected to the vacuum device;

[0053] Multiple adsorption chambers 113 are spaced apart along the second direction (Y direction) inside the adsorption platform 110, and the adjustment mechanism 140 can adjust the number of adsorption chambers 113 connected to the vacuum device.

[0054] By providing multiple adsorption chambers 113 spaced apart along the direction within the adsorption platform 110, the adsorption platform 110 can be divided into multiple adsorption areas in the second direction (Y direction). At this time, the number of adsorption chambers 113 connected to the vacuum device can be adjusted by the adjustment mechanism 140 according to the size of the plate in the second direction (Y direction), thereby adjusting the adsorption area to adapt to the size of the plate, which ensures adsorption stability and improves flexibility and practicality.

[0055] In one embodiment, the adsorption platform 110 includes a body, an adsorption cavity 113 extending through one end of the body to form a plurality of adsorption holes, and an adsorption cavity 113 extending through the other end of the body to form a plurality of connecting holes spaced apart along a second direction (Y direction). Each adsorption cavity 113 is connected to at least one connecting hole and at least one adsorption hole, and the adsorption holes are used to adsorb plates.

[0056] like Figures 5 to 6 As shown, the adjustment mechanism 140 includes a cover 141 and a separator 142. The cover 141 is mounted on the main body, and a cavity a is formed between the cover 141 and the main body. Each connecting hole can communicate with the cavity a.

[0057] The separator 142 is slidably disposed in cavity a along the second direction (Y direction) and can divide cavity a into a first cavity a1 and a second cavity a2 that are not connected to each other.

[0058] The cover 141 is provided with a vacuum hole that communicates with the second sub-cavity a2. The vacuum hole is used to connect a vacuum device.

[0059] By providing multiple adsorption cavities 113 at intervals along the second direction (Y direction) within the main body, the main body can be divided into multiple adsorption areas in the second direction (Y direction). At this time, the position of the separator 142 can be adjusted accordingly along the second direction (Y direction) based on the size of the plate in the second direction (Y direction), so that the number of connecting holes communicating with the second cavity a2 can be increased or decreased, thereby enabling the corresponding adsorption area and adapting to plates of various sizes in the second direction (Y direction).

[0060] When the number of connecting holes connected to the second sub-cavity a2 increases, the number of adsorption chambers 113 connected to the vacuum device through the vacuum holes increases, thereby increasing the number of adsorption holes connected to the vacuum device. At this time, the adsorption area of ​​the body increases, which can accommodate larger plates. When the number of connecting holes connected to the second sub-cavity a2 decreases, the number of adsorption chambers 113 connected to the vacuum device through the vacuum holes decreases, thereby decreasing the number of adsorption holes connected to the vacuum device. At this time, the adsorption area of ​​the body decreases, which can accommodate smaller plates.

[0061] In one embodiment, the adsorption device further includes a driving member 143, which is mounted on the main body and whose output end is connected to the separator 142.

[0062] The driving component 143 is used to drive the partition 142 to slide in the cavity a along the second direction (Y direction) to adjust the position of the partition 142 relative to the cavity a, thereby adjusting the position of the partition 142 relative to the cover 141 and the body, and further adjusting the number of connecting holes communicating with the second cavity a2 to adapt to plates of various sizes.

[0063] In one embodiment, the drive member 143 includes a drive motor and a lead screw. The drive motor is mounted on the body, and the output end of the drive motor is connected to the lead screw. The lead screw extends along the second direction (Y direction) and is threadedly connected to the separator 142.

[0064] At this point, the lead screw will form the output end of the drive unit 143.

[0065] Preferably, the output shaft of the drive motor can be coaxially connected to the lead screw.

[0066] By driving the lead screw to rotate by the drive motor, the separator 142, which is threadedly connected to the lead screw, will move along the second direction (Y direction). In this way, the number of connecting holes connected to the second cavity a2 can be increased or decreased according to the size of the plate along the second direction (Y direction), so as to realize the automatic adjustment of the adsorption range to adapt to plates of various sizes and improve production efficiency.

[0067] In addition, such as Figures 1 to 6 As shown, another embodiment of this utility model provides a sheet metal processing device, which includes a sheet metal processing apparatus and a sheet metal adsorption device 100 as provided in any of the above embodiments. The sheet metal processing apparatus is used to process the sheet metal adsorbed on the adsorption platform 110.

Since this sheet metal processing device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0068] In this application, the board material is PCB, and the board material processing equipment can be a drilling machine, forming machine, drilling and milling machine, exposure machine, etc., which are not limited here.

[0069] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
