Description

Technical Field

[0001] This utility model relates to circuit board packaging and processing technology, specifically a circuit board vacuum packaging device. Background Technology

[0002] With the technological development of electronic devices, printed circuits are widely used in various electronic devices. Printed circuit boards are usually manufactured in factories. When meeting market demands, the mass-produced circuit boards are vacuum-packed and then transported.

[0003] For example, announcement number CN209667453U, announcement date: 2019-11-22, discloses a vacuum packaging device for circuit board processing that facilitates dust removal, including a first base, a circuit board body slidably connected to the upper side of the first base, a first conveyor rod rotatably connected to the front right side of the first base, a third conveyor rod movably connected to the front side of the second conveyor rod, a second base fixedly connected to the left side of the first base, a second motor fixedly connected to the rear side of the first base, a conveyor chain meshing with the outer side of the second gear, and a fixing block welded to the upper side of the limiting frame.

[0004] The shortcomings of existing technology are that, since multiple circuit boards are stacked in the bag, the circuit boards move freely inside the bag. Therefore, whether it is a conveyor belt vacuum packaging machine or a fixed vacuum packaging machine, it is necessary to manually place the bag containing the circuit boards on the vacuum adsorption area and then manually calibrate the position of the bag opening. This results in deviations during manual adjustment, and the circuit boards may also shift in position inside the packaging bag. Consequently, if the circuit boards remain in a shifted state due to negative pressure after vacuum packaging, it will affect the transportation and storage of the product. Utility Model Content

[0005] The purpose of this invention is to provide a circuit board vacuum packaging device to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A circuit board vacuum packaging device includes a bag body with a raised shape and a base. Multiple pressing components are rotatably arranged on the base, and a flat plate that slides against the side of the bag body is provided on the pressing components.

[0008] The flat plate has a sloping plate fixedly installed at its end to conform to the raised side.

[0009] As a further description of the above technical solution: an arc plate that abuts against the raised outer wall is fixedly installed at the end of the inclined plate.

[0010] As a further description of the above technical solution: a sliding hole is provided on the inclined plate, and a pressure rod that moves on the outside of the bulge is slidably disposed in the sliding hole.

[0011] As a further description of the above technical solution: the pressure rod is squeezed by the arc plate in the sliding state.

[0012] As a further description of the above technical solution: one end of the sliding hole is connected to a deep hole, and the pressure rod is embedded in the deep hole, so that the pressure rod abuts against the surface of the bag.

[0013] As a further description of the above technical solution: the other end of the sliding hole is connected to a shallow hole, and the pressure rod is embedded in the shallow hole, so that the pressure rod and the bag opening maintain a predetermined distance.

[0014] As a further description of the above technical solution: a screw is fixedly installed at the end of the pressure rod.

[0015] As a further description of the above technical solution: a nut is threaded onto the screw.

[0016] As a further description of the above technical solution: a support plate is provided on the pressing component, and a position groove for the end of the support plate to slide is opened on the surface of the machine base.

[0017] As a further description of the above technical solution: a bent rod is fixedly installed in the middle of the pressure rod.

[0018] In the above technical solution, the circuit board vacuum packaging device provided by this utility model has the following beneficial effects: after the pressure is released by rotation, the two opposing flat plates apply pressure to both sides of the bag body. Then, the convex blocks squeeze the inclined plates to make them move horizontally. As the two inclined plates come closer together, the bulge is positioned and calibrated. At the same time, the ends of the arc plates that are opposite to and abut against the surface of the bag body strengthen the squeezing and fixing ability of the bulge position, effectively preventing the circuit board from shifting inside the bag.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] Please see Figure 1-4 This utility model provides a technical solution, including the following embodiments:

[0028] Example 1

[0029] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment, based on the original fixed bag opening, provides auxiliary positioning and fixation for the bag body 2 itself, replacing the tedious manual calibration and positioning. By rotating and opening the symmetrically distributed pressure pieces 3, and placing the bag body 2 on the working surface of the machine base 1, after releasing the pressure pieces 3, the two opposing flat plates 32 apply pressure to both sides of the bag body 2. Then, the protrusions squeeze the inclined plate 33 to make it move horizontally, thereby positioning and calibrating the bulge 21 as the two inclined plates 33 move closer together. At the same time, the ends of the arc plates 34 that are opposite and abut against the surface of the bag body 2 strengthen the squeezing and fixing ability of the bulge 21, effectively preventing the circuit board from shifting inside the bag body 2.

[0030] Secondly, during the horizontal movement, the flat plate 32 squeezes out air from both sides of the bag body 2, enhancing the bag body 2's ability to be vacuumed. The arc-shaped plate 34, made of elastic metal sheet, can provide elastic compression to the outer wall of the bulge 21 at its end, and can also adapt to the compression deformation of the arc plate 34 by the vacuum adsorption component pressure cap of the vacuum packaging machine.

[0031] Specifically, the base 1 is the working surface of the vacuum packaging machine used to place the bag body 2. After the circuit board is stacked inside the bag body 2, the two surfaces of the bag body 2 form a bulge 21, so that the bag body 2 is placed on the base 1.

[0032] Furthermore, such as Figure 2 As shown by the symmetrical dotted line in the middle, it is a metal protrusion separately installed on the inner wall of the vacuum adsorption component pressure cap of the vacuum packaging machine (which is existing technology and will not be described in detail here). The protrusion has rounded corners that slide in contact with the inclined plate 33 so as to generate a squeezing force on the inclined plate 33 during the box closing process.

[0033] Example 2

[0034] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment details the two pressing components 3 and the pressing rod 4 between them. The screw 42, integrally formed at both ends of the pressing rod 4, along with a nut, allows adjustment of the distance between the two pressing components 3, enabling the pressing components 3 to be positioned to fit circuit board bags 2 of different sizes.

[0035] Specifically, an annular block is integrally formed at the end of the pressure rod 4, and a spring is fixedly installed on the annular block on the outside of the pressure rod 4. The end of the spring slides on the inclined plate 33, which enables the two pressure pieces 3 to be kept at a predetermined distance under the combined action of the nut and the spring, and rubber damping is bonded in the nut.

[0036] Furthermore, the support plate 31 is integrally formed on the end of the flat plate 32, and a columnar block is welded to the end of the support plate 31. The columnar block is embedded in the position groove 11 (with the center of the circle higher than the center of the columnar block) and slides so that the two pressing parts 3 are a group and the position on the machine base 1 is adjustable, so that the packaging machine can process different specifications of circuit board packaging at the same time (the number of circuit boards placed in the bag body 2 is fixed, and the thickness of different specifications of circuit boards is generally the same, so the fixed length of the support plate 31 can be adapted to the vacuuming of the bag body 2).

[0037] Furthermore, the protrusions on the vacuum adsorption component cover of the vacuum packaging machine have the same channels and columnar block components as the position groove 11, so that the protrusions can synchronously adapt to the pressure component 3 after the spacing is adjusted.

[0038] Example 3

[0039] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the figure, this embodiment details the function of the pressure rod 4 as an auxiliary fixation of the bag body 2. When the pressure rod 4 is in the position of the deep hole 36, the pressure rod 4 and the two flat plates 32 press and fix the part of the bag body 2 except for the bag opening. Then, when the pressure rod 4 slides from the deep hole 36 into the sliding hole 35, the pressure rod 4 slides from the bottom of the bag to the surface of the raised 21, and the pressure rod 4 is used to squeeze the surface of the raised 21, causing the pressure rod 4 to help squeeze the excess gas in the bag body 2 to the bag opening, thereby enhancing the vacuuming ability of the bag body 2.

[0040] Secondly, when the pressure rod 4 slides from the sliding hole 35 into the shallow hole 37, the pressure rod 4 disengages from the protrusion 21, and because there is a gap between the end of the shallow hole 37 and the flat plate 32, the bag opening has enough space to be vacuumed.

[0041] Specifically, when the pressure rod 4 slides on the surface of the raised section 21, the arc plate 34 applies pressure to the pressure rod 4 at its end, thereby increasing the compressive strength of the pressure rod 4 on the raised section 21 under the action of elastic force. Figure 2 and Figure 3 The arrows shown represent the directions of horizontal movement of the pressure member 3 and the straight-line direction of sliding of the pressure rod 4 along the channel, respectively.

[0042] Furthermore, the bent rod 41 welded to the middle of the pressure rod 4 is convenient for manual pulling, making it easy to move the pressure rod 4. On the other hand, after the pressure rod 4 reaches the shallow hole 37, rotating the pressure rod 4 can make the bent rod 41 come into contact with the bulge 21, further enhancing the pressure effect on the bulge 21 and improving the vacuuming capacity.

[0043] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
