Description

Technical Field

[0001] This utility model belongs to the technical field of material screening devices, specifically relating to a vibrating screening mechanism and an electronic component vibrating screening device. Background Technology

[0002] LED refers to light-emitting diode, which has many advantages, wide applications, and high cost-effectiveness, and is becoming increasingly popular in industrial and daily use. With the growth in application scope and usage, users have also placed stricter requirements on the quality of LEDs. During the manufacturing process, sheet-shaped LEDs undergo a process of being de-granulated into individual LEDs. During this process, some impurities and debris are generated and mixed in with the LED particles. These impurities include metallic and non-metallic impurities. Non-metallic impurities can adhere to the surface of the LED particles due to static electricity, contaminating the LED particles, while metallic impurities can scratch the LED particles, causing quality defects.

[0003] In existing vibrating screening devices, the screens are mostly non-replaceable or inconvenient to replace, which makes it difficult to screen granular products of different sizes. Furthermore, the use of horizontal screening results in unsatisfactory screening effects. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a vibrating screening mechanism and an electronic component vibrating screening device to solve the problem that the screen of the existing vibrating screening device is not easy to disassemble and replace.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] On one hand, a vibrating screening mechanism is provided, including a housing assembly, a screening component, and a vibration assembly. The housing assembly includes an upper housing and a lower housing, which enclose a screening chamber. The screening component is stacked between the upper housing and the lower housing. Each side of the upper housing and the lower housing is provided with a connecting plate portion one, and each side of the screening component is provided with a connecting plate portion two. The connecting plate portion two is pressed between the connecting plate portion one of the upper housing and the connecting plate portion two of the lower housing. The connecting plate portion one and the connecting plate portion two are detachably connected.

[0007] The screening component divides the screening chamber into a screening chamber and a waste chamber. The screening chamber is connected to the inlet located on the upper shell and the outlet located on the shell assembly. The waste chamber is connected to the waste outlet located on the lower shell.

[0008] The vibration assembly is connected to the housing assembly to drive the screening component to vibrate.

[0009] In one possible implementation, the upper housing has an abutment portion flush with the connecting plate portion, and the lower housing has a positioning groove into which the abutment portion of the upper housing abuts.

[0010] In a possible implementation, the connecting plate portion one and / or the connecting plate portion two are provided with a settling trough adapted to the screening component for placing the screening component, the settling trough forming an interlayer channel between the upper shell and the lower shell.

[0011] In possible implementations, the screening member is inclined between the upper and lower housings, or the housing assembly is inclined.

[0012] In a possible implementation, the screening component includes an upper clamping plate, a screen, and a lower clamping plate. The screen is clamped and fixed between the upper clamping plate and the lower clamping plate. The upper clamping plate and the lower clamping plate are provided with hollow areas that avoid the screen mesh area. The upper clamping plate and the lower clamping plate are provided with pressing parts that extend toward the screen mesh area.

[0013] In one possible implementation, the upper clamping plate is symmetrically provided with pressing parts that extend obliquely toward the screen mesh area on both sides, and the pressing parts on both sides are spaced apart to form a travel channel.

[0014] In some possible implementations, a mounting base is also included, on which the housing assembly is mounted by a number of shock-absorbing supports, and a shock-damping component is also provided between the housing assembly and the mounting base.

[0015] In one possible implementation, the vibration damping component includes vibration damping springs with both ends connected to the housing assembly and the mounting base, respectively.

[0016] In one possible implementation, the waste outlet of the lower housing faces downward, and a waste box is provided below the waste outlet;

[0017] Alternatively, the waste outlet of the lower housing is connected to a vacuum cleaner.

[0018] On the other hand, a vibrating screening device for electronic components is also provided, including a vibrating screening mechanism as described in any of the above claims.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The vibrating screening mechanism of this utility model has screening components stacked between the upper shell and the lower shell. The screening components are detachably connected to the connecting plate part of the upper shell and the connecting plate part of the lower shell through the connecting plate part two provided on them. This makes it easier to replace screening components with different screen apertures, so as to facilitate the application of products with different particle sizes. Furthermore, the holding force applied by the upper shell can further make the screening components more stable.

[0021] Furthermore, by tilting the screening components, the movement path of the material particles can be tilted, ensuring effective screening and discharge of particles, improving screening efficiency. The sandwich structure of the screen can have good stability during vibration through the holding part. The tilting and spacing of the holding part can avoid blocking particles and causing particle accumulation, and can also avoid mixing of materials when changing products.

[0022] Meanwhile, the housing assembly can effectively isolate the vibration during device operation through the shock-absorbing support assembly and vibration damping components, ensuring quiet and stable operation of the device and reducing the amplitude and frequency of low-frequency operation of the equipment.

[0023] This invention relates to an electronic component vibrating screening device, which can be applied to the screening of electronic components such as LEDs. After the LED sheet products are granulated into individual particles, they enter the housing assembly through the feed hopper. The vibrating motor drives the vibrating screen to shake at a set frequency. The housing assembly is separated by a screen, and impurities fall into the lower housing through the screen holes. Under the action of vibration, they fall into the bottom waste box through the dust collection port, and the LED particles are discharged from the discharge port. Attached Figure Description

Detailed Implementation

[0032] 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 specific embodiments.

[0033] Please refer to Figure 1-7 As shown, an embodiment of this application provides a vibrating screening mechanism, including a housing assembly 1, a screening component 12, and a vibration assembly 3. The housing assembly 1 includes an upper housing 11 and a lower housing 13, which enclose a screening chamber. The screening component 12 is stacked between the upper housing 11 and the lower housing 13. Both the upper housing 11 and the lower housing 13 have a connecting plate portion 18 on their sides, and the screening component 12 has a connecting plate portion 121 on its side. The connecting plate portion 121 is pressed between the connecting plate portion 18 of the upper housing 11 and the connecting plate portion 121 of the lower housing 13. The connecting plate portion 1 and the connecting plate portion 121 are detachably connected.

[0034] The housing assembly 1 is divided into an upper housing 11 and a lower housing 13, which can be enclosed to form a screening chamber. The screening chamber allows material particles to easily enter and be screened by the screening component 12. The screening component 12 is used to screen material particles, removing waste materials smaller than the material particle size, and discharging the screened waste materials. The screening component 12 is stacked between the upper housing 11 and the lower housing 13, and is detachably connected to the connecting plate portion 18 on the upper housing 11 and the lower housing 13 through a connecting plate portion 2 121 provided on its side. This allows the screening component 12 to be firmly held and fixed between the upper housing 11 and the lower housing 13, and also allows for easy replacement of the screen plate through the detachable connection. After disconnection, the screening component can be removed from between the upper housing 11 and the lower housing 13, thus facilitating the replacement of the screening component 12 from the outside, and allowing the replacement of screening components 12 with different screen apertures—suitable for products with different material particle sizes.

[0035] The detachable connection between the connecting plate part 18 and the connecting plate part 2 121 and the screening component 12 can be a snap-fit ​​connection or a bolt connection. In specific implementation, a bolt connection is preferred. When using a bolt connection, multiple connecting holes can be provided along the length direction on the connecting plate part 18 and the connecting plate part 2 121. During installation, it is only necessary to align the upper and lower connecting holes to connect them with bolts, which is also convenient for disassembly and assembly.

[0036] In the specific implementation process, the upper shell 11, the lower shell 13, and the screening component 12 are all oriented. The connecting plate part 18 and the connecting plate part 121 are both arranged circumferentially on at least two sides. When they are arranged on two sides, the two sides are opposite sides, which makes it easy to remove them in opposite directions. When three adjacent sides are arranged, the screening component 12 can be removed from different sides. Alternatively, the upper shell 11 can be completely removed before the screening component 12 can be removed.

[0037] In an embodiment of this application, the screening component 12 divides the screening chamber into a screening chamber 111 and a waste chamber 131. The screening chamber 111 is connected to the inlet 16 provided on the upper shell 11 and the outlet 15 provided on the shell assembly 1. The waste chamber 131 is connected to the waste outlet 132 provided on the lower shell 13. The vibration component 3 is connected to the shell assembly 1 to drive the screening component 12 to vibrate.

[0038] The screening component 12 divides the screening chamber into a screening chamber 111 and a waste chamber 131. The screening chamber 111 is used to screen the material particles entering it through the screening component 12, separating the target material particles and the waste entering the waste chamber 131. The target material particles are discharged through the discharge port 15 connected to the screening chamber 111, and the waste is discharged through the waste outlet 132, thus realizing the screening of materials. The vibration component 3 is used to generate vibration and drive the screening component 12 to vibrate, so that the material particles on the screening component 12 can be screened during the vibration process.

[0039] Through the above technical solution, a screening component 12 is stacked between the upper shell 11 and the lower shell 13. The screening component 12 is detachably connected to the connecting plate portion 18 of the upper shell 11 and the lower shell 13 through the connecting plate portion 2 121 provided thereon. This makes it easier to replace screening components 12 with different screen apertures, thereby making it easier to apply to product particles of different sizes. Furthermore, the holding force applied by the upper shell 11 can further make the screening component 12 more stable.

[0040] In one embodiment, the connecting plate portion 18 and / or the connecting plate portion 121 are provided with a settling trough 133 adapted to the screening member 12 for placing the screening member 12, and the settling trough 133 forms an interlayer channel between the upper shell 11 and the lower shell 13.

[0041] The settling trough 133 is a groove-shaped structure with a recessed or concave connecting surface to the connecting plate part 18 or the connecting plate part 2 121, forming a recessed stepped surface. The screening component 12 is placed and supported on this recessed stepped surface. The stepped settling trough 133 can reduce the pressure exerted by the upper shell 11 on the screening component 12, and can also form a sandwich channel between the upper shell 11 and the lower shell 13. The sandwich channel can facilitate the removal or installation of the screening component 12 from the sandwich channel, thereby enabling more convenient disassembly and assembly.

[0042] Furthermore, to facilitate the installation of the screening component 12, please refer to... Figure 2 As shown, the upper housing 11 is provided with an abutment portion 114 that is flush with the connecting plate portion 18, and the lower housing 13 is provided with a positioning groove 134 into which the abutment portion 114 of the upper housing 11 abuts.

[0043] In this way, the abutment part 114 provided on the upper housing 11 is flush with the connecting plate part 18. The abutment part 114 abuts into the positioning groove 134 provided on the lower housing 13. The cooperation between the flush abutment part 114 and the positioning groove 134 can realize the positioning and installation of the upper housing 11 on the lower housing 13. Furthermore, the groove opening of the positioning groove 134 is parallel to the abutment part 114. In this way, the positioning groove 134 can also restrict the abutment part 114 so that the other end of the upper housing 11 will not be pressed down due to the setting of the sink trough 133, thereby making it easier to disassemble and assemble the screening frame.

[0044] In order to facilitate better screening of materials during vibration, in some embodiments, the screening component 12 is inclinedly arranged between the upper shell 11 and the lower shell 13, or the shell assembly 1 is inclinedly arranged.

[0045] The screening component 12 can be inclined between the upper shell 11 and the lower shell 13. In this case, the shell 13 does not need to be inclined. The screening component can be in the shell assembly 1 without inclination. Instead, the shell assembly 1 is inclined, which can also achieve the inclination of the screening component 12. This can facilitate the material to change position during vibration for flexible screening, and also allow it to move along the inclined direction to the discharge port 15 for discharge, thus achieving a better screening effect.

[0046] Please refer to Figure 6 and Figure 7As shown, in a preferred embodiment of the screening component 12, the screening component 12 includes an upper clamping plate 122, a screen 123, and a lower clamping plate 124. The screen 123 is clamped and fixed between the upper clamping plate 122 and the lower clamping plate 124. The upper clamping plate 122 and the lower clamping plate 124 are provided with a hollow area 1221 that avoids the mesh area of ​​the screen 123. The upper clamping plate 122 and the lower clamping plate 124 are provided with a pressing part 125 extending into the mesh area of ​​the screen.

[0047] The screen 123 is clamped between the upper clamping plate 122 and the lower clamping plate 124. The upper clamping plate 122 and the lower clamping plate 124 are then welded together. The pressing parts 125 provided on the upper clamping plate 122 and the lower clamping plate 124 can stably press the screen 123, which has a large area, to prevent the screen 123 from vibrating too much during the vibrating screening process, thus making the screening more stable and reliable.

[0048] Based on this, to prevent the holding parts 125 from obstructing the passage of materials during vibrating screening, the upper clamping plate 122 is symmetrically provided with holding parts 125 extending inclined towards the screen mesh area on both sides, and the holding parts 125 on both sides form a travel channel at intervals. In this way, the inclined holding parts 125 can play a guiding role, allowing the material to vibrate and move towards the discharge port 15 along the guiding direction, and also preventing the holding parts 125 from blocking and accumulating material particles, so as to prevent the material accumulated in the screen holes from mixing with materials of different particle sizes when changing products, and ensuring that there is basically no material retention during the change.

[0049] To ensure the screening mechanism operates quietly and stably, combined with Figure 1 and Figure 2 As shown, it also includes a mounting base 6. The housing assembly 1 is mounted on the mounting base 6 via several vibration-damping supports 4. A vibration damping component 5 is also provided between the housing assembly 1 and the mounting base 6. The housing assembly 1 is mounted on the mounting base 6 and is suspended on the mounting base 6 via the vibration-damping supports 4. The vibration-damping supports 4 are used to dampen vibration and support the housing assembly 1 to reduce the overall vibration amplitude during the vibration screening process, making the operation more stable. In addition, the vibration damping spring component can reduce the amplitude and frequency of the equipment during low-frequency operation, making the equipment operation more stable and quiet.

[0050] Preferably, the vibration damping component 5 includes vibration damping springs connected at both ends to the housing assembly 1 and the mounting base 6, respectively. The vibration damping springs are tension springs. The vibration damping support component 4 may include two connecting posts 41 and a vibration damping spring 42 disposed between the two connecting posts 41.

[0051] In practical implementation, waste collection can be carried out in several ways. One method is to have the waste outlet 132 of the lower housing 13 facing downwards, with a waste box 8 located below the waste outlet 132 for waste collection. Another method is to connect a vacuum cleaner to the waste outlet of the lower housing 13, which is helpful for dealing with heavily dusty situations. The above implementation methods can be selected and configured according to specific needs or actual conditions.

[0052] In addition, combined Figures 1-5 As shown, a feeding hopper 2 can be installed at the feed inlet 16 of the upper housing 11 for feeding, making feeding more convenient and stable. The discharge outlet 15 is constructed at the end of the lower housing 13 opposite to the feed inlet 16, specifically as a discharge channel 17 extending along the material travel direction. The discharge channel 17 is connected to the screening chamber 111, and the inner bottom surface of the screening channel is flush with or lower than the top surface of the screening component 12, so that the screened material can smoothly enter the discharge channel 17. A shock-absorbing pad 7 can also be installed under the mounting base 6 to further improve the shock absorption effect. A window 112 can be installed at the top of the upper housing 11, and an acrylic plate 113 can be installed in the window 112 to form a transparent viewing window 14, which is more convenient for observing the screening of the internal material. The vibrating component adopts a vibrating motor, and the vibrating motor can also be equipped with a speed controller (not shown in the figure) to set a suitable vibration frequency for different product splits.

[0053] Embodiments of this application also provide an electronic component vibrating screening device, including a vibrating screening mechanism as described in any of the above technical solutions.

[0054] The electronic component vibrating screening device can be applied to the screening of electronic components such as LEDs. After the LED sheet products are degranulated into individual granules, they enter the housing assembly 1 through the feed funnel. The vibrating motor drives the vibrating screen to shake at a set frequency. The housing assembly 1 is separated by a screen 123. Impurities fall into the lower housing 13 through the gaps in the screen 123. Under the action of vibration, they fall into the bottom waste box 8 through the dust collection port. The LED particles are discharged from the discharge port 15.

[0055] The above are merely preferred embodiments of this utility model. It should be noted that the above preferred embodiments should not be considered as limitations on this utility model, and the scope of protection of this utility model should be determined by the scope defined in the claims. For those skilled in the art, several improvements and modifications can be made without departing from the spirit and scope of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
