suction cup device

Abstract

This utility model discloses a suction cup device with a fixed bracket, including the fixed bracket and a suction cup assembly. The suction cup assembly can be connected to an SMT depaneling machine through the fixed bracket, improving the stability of the suction cup assembly during use. A sealed cavity is formed by a fixed connection between a top plate and a bottom plate. Each air pipe is connected to the top plate, and each suction nozzle is connected to the bottom plate, so that each air pipe and each suction nozzle is connected to the sealed cavity. When the suction nozzle contacts the surface of the PCB, the air pipe extracts the air from the sealed cavity, creating a negative pressure in the sealed cavity, thereby allowing the suction nozzle to pick up the PCB board. This simplifies the structural design of traditional suction cups, allowing the suction cup device to achieve a stable vacuum adsorption effect by using fewer air pipes. It eliminates the process of installing suction nozzle rods, improving the production efficiency of the equipment, and at the same time avoids interference and folding between air pipes, ensuring the vacuum reliability of the suction cup.

Description

Technical Field

[0001] This utility model relates to the field of PCB board manufacturing technology, and in particular to a suction cup device. Background Technology

[0002] SMT depaneling machines are used in surface mount technology (SMT) production lines to divide assembled PCBs into individual circuit boards. The suction cups of SMT depaneling machines play a crucial role in fixing, positioning, buffering, and adapting to different material types during the depaneling process. They are one of the core components ensuring depaneling accuracy, quality, and efficiency. Traditional depaneling machine suction cups use a single iron plate, such as... Figure 3 As shown, holes need to be drilled according to the product suction position to install a large number of suction rods. For example, an 18-piece PCB requires as many as 40 suction rods, which makes the installation space for the suction rods small and makes it difficult to use tools to tighten the nuts, resulting in a long production time. In addition, each suction rod needs to be connected to the vacuum circuit separately. The air pipes are prone to interference and folding during equipment movement, resulting in insufficient vacuum and difficulty in ensuring the vacuum reliability of the suction cup. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a suction cup device.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A suction cup device includes: a fixed bracket and a suction cup assembly. The fixed bracket includes a fixed plate, multiple connecting rods, and limiting members. Each connecting rod is movably inserted through the fixed plate. One end of each connecting rod is fixedly connected to a top plate, and the other end of each connecting rod is fixedly connected to the limiting members. The suction cup assembly is disposed below the fixed bracket. The suction cup assembly includes a top plate, a bottom plate, multiple air pipes, and suction nozzles. The top plate and the bottom plate are fixedly connected to form a sealed cavity. Each air pipe is connected to the top plate, and each suction nozzle is connected to the bottom plate. Each air pipe and each suction nozzle communicates with the sealed cavity. The bottom plate has multiple first grooves forming multiple first vacuum circuits. The first vacuum circuits are used to pick up good PCB boards. The bottom plate has multiple second grooves forming second vacuum circuits. The second vacuum circuits are used to pick up scrap edges of PCB boards.

[0006] In one embodiment, one end of each connecting rod is bolted or engaged with the top plate, and the other end of each connecting rod is bolted or engaged with each limiting member.

[0007] In one embodiment, the fixed bracket further includes a plurality of limiting tubes, each of the limiting tubes being respectively disposed on the fixed plate, and each of the connecting rods being movably disposed on each of the limiting tubes.

[0008] In one embodiment, the fixing bracket further includes a plurality of buffers, each of which is respectively sleeved on each of the connecting rods.

[0009] In one embodiment, the fixing bracket further includes a plurality of fixing holes, which are evenly distributed on the fixing plate.

[0010] In one embodiment, the suction cup assembly includes a plurality of fixing plates and a locking member. The top plate has a plurality of first fixing holes, and the bottom plate has a plurality of second fixing holes. Each of the first fixing holes is aligned with each of the second fixing holes. The fixing plates are disposed between the first fixing holes and the second fixing holes, and the locking member passes through the fixing plates.

[0011] In one embodiment, the suction cup assembly further includes at least one anti-fool post, each of the anti-fool posts being disposed between the top plate and the bottom plate.

[0012] In one embodiment, the suction cup assembly further includes a first sealing strip and a second sealing strip, the first sealing strip being disposed around the first groove and the second sealing strip being disposed around the second groove.

[0013] In one embodiment, the suction cup assembly further includes two handholds, which are symmetrically distributed on both sides of the base plate.

[0014] In one embodiment, the suction cup assembly further includes a plurality of sealing rings, each of which is disposed at the connection between the suction nozzle and the base plate.

[0015] Compared with the prior art, the present invention has at least the following advantages:

[0016] 1. By setting a fixed plate, multiple connecting rods and limiting components, each connecting rod can be movably inserted through the fixed plate, so that when the suction cup device picks up the PCB, the fixed bracket can drive the suction cup assembly to float slightly upward, avoiding the suction cup device from squeezing or vibrating the PCB, which would cause the PCB to shift in position, thus improving the stability of the suction cup assembly during use.

[0017] 2. The suction cup device of this utility model forms a sealed cavity by fixing the top plate and the bottom plate together. Each air pipe is connected to the top plate and each suction nozzle is connected to the bottom plate, so that each air pipe and each suction nozzle is connected to the sealed cavity. When the suction nozzle contacts the surface of the PCB, the air pipe draws out the air in the sealed cavity, so that a negative pressure is formed in the sealed cavity, thereby allowing the suction nozzle to pick up the PCB board. This simplifies the structural design of traditional suction cups. This suction cup device uses fewer air pipes to achieve a stable vacuum adsorption effect for the suction nozzles, eliminates the process of installing suction nozzle rods, improves the production efficiency of the equipment, and avoids interference and folding between air pipes, ensuring the vacuum reliability of the suction cup.

[0018] 3. By creating multiple first vacuum circuits through multiple first grooves on the base plate, and multiple second vacuum circuits through multiple second grooves on the base plate, the first and second vacuum circuits respectively pick up the good and waste edges of the PCB. Before the suction cup assembly moves the PCB to the downstream equipment, the PCB is moved to the waste box. First, the suction nozzles in the first vacuum circuit area continue to pick up the PCB, while the suction nozzles in the second vacuum circuit area stop picking up the PCB, allowing the waste edges of the PCB to be discharged into the waste box. Then, the good PCB is moved to the downstream equipment, and the suction nozzles in the first vacuum circuit area stop picking up the PCB, allowing the good PCB to be discharged into the downstream equipment. With this setup, the good and waste edges of the PCB can be sorted and discharged in one go, further improving production efficiency. Attached Figure Description

[0024] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0025] Please see Figure 1 and Figure 2 A suction cup device 10 includes: a fixed bracket 100 and a suction cup assembly 200. The fixed bracket 100 includes a fixed plate 110, a plurality of connecting rods 120 and limiting members 130. Each connecting rod 120 is movably inserted into the fixed plate 110. One end of each connecting rod 120 is fixedly connected to a top plate 210, and the other end of each connecting rod 120 is fixedly connected to each limiting member 130. The suction cup assembly 200 is disposed below the fixed bracket 100 and includes a top plate 210, a bottom plate 220 and a plurality of air tubes. The top plate 210 and bottom plate 220 are fixedly connected to form a sealed cavity, with each air pipe 230 connected to the top plate 210 and each suction nozzle 240 connected to the bottom plate 220. Each air pipe 230 and each suction nozzle 240 are connected to the sealed cavity. The bottom plate 220 has multiple first grooves 221 to form multiple first vacuum circuits, which are used to pick up good boards from the PCB. The bottom plate 220 has multiple second grooves 222 to form second vacuum circuits, which are used to pick up the scrap edges of the PCB.

[0026] It should be noted that by setting a fixed plate 110, multiple connecting rods 120, and limiting members 130, each connecting rod 120 can be movably inserted into the fixed plate 110. This allows the fixed bracket 100 to slightly float the suction cup assembly 200 upwards during the suction cup device 10's PCB-picking process, preventing the suction cup device 10 from squeezing or vibrating the PCB and causing displacement of the PCB, thus improving the stability of the suction cup assembly 200 during use. A sealed cavity is formed by the fixed connection between the top plate 210 and the bottom plate 220, and then each air pipe 230 is connected to the top plate 210 and the bottom plate 220 respectively. The board 210 is connected, and each suction nozzle 240 is connected to the base plate 220, so that each air pipe 230 and each suction nozzle 240 are connected to the sealed cavity. When the suction nozzle 240 contacts the surface of the PCB, the air pipe 230 draws out the air from the sealed cavity, creating a negative pressure in the sealed cavity, thereby allowing the suction nozzle 240 to pick up the PCB board. This simplifies the structural design of traditional suction cups. For example, a traditional PCB depaneling machine suction cup requires 40 air pipes 230 to pick up 18-panel PCBs, while this suction cup device 10 only needs 9 air pipes 230 to pick up 18-panel PCBs. The Deben suction cup device 10 achieves a stable vacuum adsorption effect for the suction nozzle 240 by using fewer air tubes 230, eliminating the need for installing a suction nozzle rod, thus improving equipment production efficiency. It also avoids interference and folding between air tubes 230, ensuring the vacuum reliability of the suction cup. Furthermore, by creating multiple first vacuum circuits through multiple first grooves 221 on the base plate 220, and multiple second vacuum circuits through multiple second grooves 222 on the base plate 220, the suction nozzles 240 in the first and second vacuum circuit regions respectively pick up the PCB. Before the suction cup assembly 200 moves the PCB to the downstream equipment, the PCB is moved to the waste box. First, the suction nozzle 240 in the first vacuum circuit area continues to suck up the PCB, while the suction nozzle 240 in the second vacuum circuit area stops sucking up the PCB. This allows the waste PCB edge to be unloaded into the waste box. Then, the good PCB is moved to the downstream equipment, and the suction nozzle 240 in the first vacuum circuit area stops sucking up the PCB. This allows the good PCB to be unloaded into the downstream equipment. This setup allows for the sorting and unloading of the good PCB and the waste PCB edge in one go, further improving production efficiency.

[0027] Please refer to it again. Figure 1In one embodiment, one end of each connecting rod 120 is bolted or snapped to the top plate 210, and the other end of each connecting rod 120 is bolted or snapped to the limiting member 130. The suction cup assembly 200 can be quickly disassembled and replaced according to the type of PCB, which improves the efficiency of line changing and reduces equipment downtime. Since the reliability of bolted connection is higher than that of snap-fit ​​connection, in order to improve the working stability of suction cup device 10, preferably, the connecting rod 120 is connected to the top plate 210 and the limiting member 130 by bolting.

[0028] Please refer to it again. Figure 1 In one embodiment, the fixed bracket 100 further includes a plurality of limiting tubes 140, each limiting tube 140 being respectively inserted into the fixed plate 110, and each connecting rod 120 being movably inserted into each limiting tube 140, thereby enhancing the guiding nature of the connecting rod 120, improving the accuracy of the suction cup assembly 200 in picking up the PCB, and at the same time improving the stability of the connecting rod 120, thus preventing the suction cup assembly 200 from shifting when picking up the PCB.

[0029] Please refer to it again. Figure 1 In one embodiment, the fixed bracket 100 further includes multiple buffers 150, each buffer 150 being sleeved on each connecting rod 120, which reduces the impact force of the suction cup assembly 200 when it moves up and down, further reducing the displacement of the PCB caused by vibration, thereby improving the suction accuracy of the suction cup assembly 200 on the PCB.

[0030] Please refer to it again. Figure 1 In one embodiment, the fixed bracket 100 further includes a plurality of fixing holes 160, each fixing hole 160 being evenly distributed on the fixed plate 110. The fixing holes 160 are used to fix each fixing pin according to the model of the PCB separator, so that the fixed bracket 100 can be adapted to different models of PCB separators, improving the versatility and flexibility of the device, thereby further improving the line changing efficiency and reducing equipment downtime.

[0031] Please refer to it again. Figure 1 and Figure 2 In one embodiment, the suction cup assembly 200 includes multiple fixing plates 250 and locking members. The top plate 210 has multiple first fixing holes, and the bottom plate 220 has multiple second fixing holes. Each first fixing hole is aligned with each second fixing hole. The fixing plates 250 are disposed between the first fixing holes and the second fixing holes, and the locking members are inserted through the fixing plates 250. In this embodiment, the fixing plates 250 are threaded fixing plates, and the locking members are threaded locking members, which improves the reliability of the connection between the top plate 210 and the bottom plate 220, ensures the reliability of the sealed cavity, and avoids vacuum leakage.

[0032] Please refer to it again. Figure 2 In one embodiment, the suction cup assembly 200 further includes at least one anti-misfit post 260, each anti-misfit post 260 being disposed between the top plate 210 and the bottom plate 220. The anti-misfit post 260 can prevent incorrect assembly of the top plate 210 and the bottom plate 220, ensuring that the top plate 210 and the bottom plate 220 are installed correctly, thereby improving the assembly efficiency of the suction cup assembly 200.

[0033] Please refer to it again. Figure 2 In one embodiment, the suction cup assembly 200 further includes a first sealing strip 270 and a second sealing strip 280. The first sealing strip 270 is disposed around the first groove, and the second sealing strip 280 is disposed around the second groove, which improves the airtightness of the first vacuum circuit and the second vacuum circuit, avoids mutual interference between the first vacuum circuit and the second vacuum circuit, and makes the reliability of the first vacuum circuit and the second vacuum circuit higher.

[0034] Please refer to it again. Figure 2 In one embodiment, the suction cup assembly 200 further includes two handheld parts 290, which are symmetrically distributed on both sides of the base plate 230. This facilitates manual gripping of the suction cup assembly 200 by the handheld parts 290 during disassembly and replacement, preventing deformation of the sealed cavity area caused by manual gripping during disassembly and replacement, which would affect the airtightness of the sealed cavity area.

[0035] In one embodiment, the suction cup assembly 200 further includes multiple sealing rings, each of which is disposed at the connection between each suction nozzle 240 and the base plate 220, thereby improving the sealing performance of the suction cup and further ensuring the sealing effect of the sealed cavity.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
