Description

Technical Field

[0001] This utility model relates to the field of product tray collection technology, and in particular to an automatic tray sieving mechanism. Background Technology

[0002] After small parts are processed, they need to be collected on trays for subsequent processing or packaging. The tool used for tray collection is generally a jig screen tray, which has multiple collection slots, each corresponding to a small part.

[0003] However, in existing technologies, the following two methods are used to collect small parts on trays: 1. Workers use tweezers or other tools to pick up the processed small parts one by one and place them into the collection groove of the fixture screen; 2. A batch of small parts are placed on the fixture screen, and then workers sift the fixture screen, so that the small parts are sifted into the collection groove, while excess small parts are sifted down. Although both of the above methods can achieve the collection of small parts on trays, the efficiency of manual operation is low, and the labor intensity and cost are high, which is not conducive to the development of enterprises. Utility Model Content

[0004] The purpose of this invention is to provide an automatic sieving mechanism that reduces labor costs and improves efficiency.

[0005] To solve the above technical problems, the present invention can be implemented using the following technical solutions:

[0006] An automatic sieving mechanism includes a base, a drive unit, a sieving frame, a fixed frame, and a sieve disc. The drive unit is mounted on the base, and its output end is connected to the sieving frame. The drive unit can drive the sieving frame to move back and forth. The fixed frame is tilted on the sieving frame by an adjusting component. The sieve disc includes a base plate and a fixture plate. The base plate is mounted on the fixed frame, and the fixture plate is mounted on the base plate. Several collection grooves are formed on the fixture plate. When the drive unit drives the sieving frame to move back and forth, the sieve disc will move back and forth accordingly to sieve the product into the collection grooves.

[0007] In one embodiment, the top of the base plate is provided with an inwardly recessed loading groove, and the jig plate is detachably installed in the loading groove. A retaining edge is provided at the top edge of the base plate, and the retaining edge has a notch. When the base plate is installed on the fixed frame, the notch is located in the downward inclined direction.

[0008] In one embodiment, the bottom of the base plate is provided with a downwardly protruding limiting platform, and the size of the limiting platform is adapted to the inner frame size of the fixed frame.

[0009] In one embodiment, the jig plate is further provided with protruding posts on its side.

[0015] This utility model relates to an automatic tray-sieving mechanism. A batch of products to be trayed is placed on a tray and the tray is installed on a fixed frame. A drive unit drives the tray frame to move back and forth. As the tray frame moves, it moves the fixed frame along with the tray, causing the tray to move back and forth as well. This sieving process screens the products on the tray. During the sieving process, some products are sifted off while others are sifted into the collection trough of the fixture plate, thus achieving automatic sieving and collection of products. The automated sieving process improves the efficiency of product collection and tray placement and effectively reduces manual labor intensity and labor costs. Attached Figure Description

[0020] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0021] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. Conversely, when an element is said to be "directly on" another element, there is no intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] Please see Figure 1 and Figure 2 An automatic sieving mechanism includes a base 100, a drive unit 200, a sieving frame 300, a fixed frame 400, and a sieve disc 500. The drive unit 200 is mounted on the base 100, and its output end is connected to the sieving frame 300. The drive unit 200 can drive the sieving frame 300 to move back and forth. The fixed frame 400 is inclinedly mounted on the sieving frame 300 via an adjusting member 600. The sieve disc 500 includes a base plate 510 and a fixture plate 520. The base plate 510 is mounted on the fixed frame 400, and the fixture plate 520 is mounted on the base plate 510. Several collection grooves 521 are provided on the fixture plate 520. When the drive unit 200 drives the sieving frame 300 to move back and forth, the sieve disc 500 will move back and forth accordingly to sieve the product into the collection grooves 521.

[0024] Specifically, in this embodiment, the jig plate 520, the base plate 510, and the fixing frame 400 are all detachably connected. The jig plate 520 is used for collecting and arranging products, so it is provided with several collection troughs 521. When collecting products, the jig plate 520 is installed onto the base plate 510 to form a sieve tray 500, and then the sieve tray 500 is installed onto the fixing frame 400. After installation, a batch of products to be collected and arranged is poured onto the sieve tray 500, and the driving component 200 drives the screening frame 300 to move back and forth. When the screening frame 300 moves, it carries the fixing frame 400 along with it, thereby causing the sieve tray 500 on the fixing frame 400 to move back and forth. The screen 500 is used to screen the products. Because the fixed frame 400 is tilted, some products will be screened into the collection trough 521 for collection while the excess products will be screened off and collected. When all the excess products on the screen 500 have been screened off, the drive unit 200 stops running and the fixture plate 520 on the base plate 510 is removed for inspection. If the collection troughs 521 are full, the products can be placed on trays for subsequent processing or packaging. If there are any unfilled collection troughs 521, workers can fill them themselves. In the end, by automating the screening of the screen 500, the efficiency of product collection and traying can be improved, and the intensity of manual labor and labor costs can be effectively reduced.

[0025] In order to ensure that the drive component 200 can drive the screen plate 500 to move back and forth, the drive component 200 in this embodiment is a reciprocating motor. The reciprocating motor drives the screen frame 300 to move left and right, thereby realizing the reciprocating movement of the screen plate 500 to ensure that the products on the screen plate 500 are screened.

[0026] In addition, the base plate 510 in this embodiment is made of bakelite, while the fixture plate 520 is made of acrylic. Both bakelite and acrylic materials are widely available and have relatively mature production processes, which can reduce the manufacturing cost of the swivel screen mechanism. Bakelite has high mechanical strength and hardness, as well as excellent dimensional stability, while acrylic has the advantages of being lightweight, strong (impact resistant), and easy to process. Therefore, the screen plate 500 has a good overall lifespan and is easy to produce.

[0027] Furthermore, to ensure that excess product on the sieve tray 500 is sieved off during the reciprocating movement of the sieve tray 500, the horizontal tilt angle of the fixed frame 400 is 5°-10° in this embodiment. When the horizontal tilt angle of the fixed frame 400 is greater than 10°, the product will slide directly downwards after being poured onto the sieve tray 500, which is not conducive to the sieving process. When the horizontal tilt angle of the fixed frame 400 is less than 5°, the product on the sieve tray 500 is not easily sieved off during the sieving process, which leads to a longer sieving time. Therefore, setting the horizontal tilt angle of the fixed frame 400 to 5°-10° is optimal, thereby ensuring the sieving effect and improving efficiency.

[0028] Please see Figure 2 To facilitate the assembly and disassembly of the jig plate 520, in this embodiment, an inwardly recessed loading groove 511 is provided on the top of the base plate 510. The size of the jig plate 520 is suitable for the loading groove 511, so that the jig plate 520 can be easily installed into or removed from the loading groove 511. Of course, in order to remove the jig plate 520 from the loading groove 511, a protruding post 522 is also provided on the side of the jig plate 520. The protruding post 522 facilitates the extraction by a robot or manual labor, so as to facilitate the assembly and disassembly of the jig plate 520.

[0029] Meanwhile, to facilitate the placement of batches of products on the sieve tray 500, a retaining edge 512 is provided at the top edge of the base plate 510, and the retaining edge 512 has a notch. When the base plate 510 is installed on the fixed frame 400, the notch is located in a downward inclined direction. The retaining edge 512 ensures that when the sieve tray 500 moves back and forth, the products on the sieve tray 500 will not be screened off from the direction of the retaining edge 512, but will only slide off sequentially from the direction of the notch. This makes the structural design of the sieve tray 500 reasonable and facilitates the screening and collection of products.

[0030] Please see Figure 2 In order to facilitate the installation of the bottom plate 510 of the screen plate 500 onto the fixed frame 400, a downwardly protruding limiting platform 513 is provided at the bottom of the bottom plate 510. The size of the limiting platform 513 is adapted to the inner frame size of the fixed frame 400. By installing the limiting platform 513 into the inner frame of the fixed frame 400, the limiting between the bottom plate 510 and the fixed frame 400 is achieved, ensuring that when the screen frame 300 moves left and right, the fixed frame 400 can carry the screen plate 500 to screen left and right. The limiting platform 513 also allows for easy disassembly and assembly of the bottom plate 510 of the screen plate 500.

[0031] To prevent the limiting platform 513 from failing to insert into the inner frame of the fixed frame 400, the adjusting member 600 in this embodiment uses an internal hexagon screw. After the adjusting member 600 is used to fix the fixed frame 400 and the screen frame 300, its head is flush with the inner frame surface of the fixed frame 400. The head of the adjusting member 600 is the part that the internal hexagon screw is tightened on. By tightening the head of the adjusting member 600 until it is flush with the inner frame surface of the fixed frame 400, the limiting platform 513 at the bottom of the base plate 510 can be easily inserted into the inner frame of the fixed frame 400, thus achieving the installation between the screen plate 500 and the fixed frame 400.

[0032] Finally, in order to facilitate the installation of the screen plate 500 onto the fixed frame 400, the screen rack 300 in this embodiment has a 'U' shaped structure, that is, the top of the screen rack 300 is open. The open top of the screen rack 300 allows the robot arm to easily install the screen plate 500 onto the fixed frame 400 or remove it from the fixed frame 400.

[0033] In addition, the bottom of the screening frame 300 is slidably connected to the base 100 via a linear slide rail 700. When the drive component 200 drives the screening frame 300 to move back and forth, the screening frame 300 will move along the linear slide rail 700, thereby making the screening frame 300 move more smoothly and ensuring the left and right screening of the screen plate 500.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description; however, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model; furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
