Description

Technical Field

[0001] The utility model relates to the field of contacts, in particular to an automatic screening and classification device for contacts. Background Art

[0002] The contact is the junction or contact surface between two conductors through which current can pass. Contacts are divided into two categories: one is contacts that rely on electromagnetic force or manual operation, such as contactors, electric relays, switches, buttons, etc.; the other is contacts that are non-electrical and non-manually operated, such as electric relays, travel switches, etc. After mass production, contacts need to be classified by screening devices due to their different sizes. The principle of the screening machine is to use a sieve to separate different particles and components. For example, in the production of mixed materials, particles of different sizes and shapes are separated so that the materials can meet different production requirements.

[0003] After searching, a device for magnetic contact screening with publication number CN211436565U is found, which specifically discloses a device for magnetic contact screening, including a body, a speed limit plate and a supporting foot, the body is shovel-shaped, and the body is tilted and fixedly installed above the supporting foot frame, and adjusting rods are vertically arranged on both sides of the middle part of the body, and a waist-shaped hole is vertically arranged on the adjusting rod, the speed limit plate is U-shaped and vertically inserted into the body, and the side walls on both sides of the speed limit plate lean against the adjusting rod and are connected to the fasteners passing through the waist-shaped holes, a placing part is formed between the speed limit plate and the closed end of the body, and a screening part is formed between the speed limit plate and the open end of the body, and a plurality of strong magnets are installed at a position corresponding to the screening part below the body. The utility model achieves the requirement of screening the magnetic contacts by making a shovel-shaped device with a certain angle and arranging a strong magnet below it, thereby sucking the magnetic contacts and avoiding mixing of the magnetic contacts.

[0004] During use, the existing contact screening device produces contacts of different sizes and types, and all the contacts are mixed together, making it difficult to distinguish and screen them manually. The screening device only screens the contacts through a layer of screening net. This screening method is too simple and not detailed enough. The separated contacts still need to be screened manually for a second time. In addition, the above-mentioned comparative cases also lack the function of automatic screening and classification of contacts of different types and sizes. This not only easily prolongs the contact screening time, but also has low screening efficiency and high labor intensity for workers. It also lacks the ability of automatic screening and classification, which reduces the overall scope of use of the device.

[0005] Therefore, it is necessary to invent a contact automatic screening and classification device to solve the above problems. Utility Model Content

[0006] The utility model aims to provide an automatic screening and classification device for contacts, which can classify and screen contacts into three categories through a coarse screening filter, a contact discharge port, a discharge plate, a medium screening filter, a fine screening filter, a small hydraulic cylinder and a discharge push plate, thereby increasing the screening intensity of contacts and avoiding the tedious operation of subsequent manual secondary screening of contacts. Moreover, the entire screening process does not require manual intervention and is fully automated, thus meeting the purpose of automatic screening and classification of different types and sizes, and also expanding the scope of use of the device, reducing the manpower loss caused by manual operation, and improving the screening efficiency of contacts, so as to solve the problems of the prior art During the use of the contact screening device, since the contacts produced are of different sizes and types, the contacts are all mixed together and it is difficult to distinguish and screen them manually. The screening device only screens the contacts through a layer of screening net. This screening method is too simple and not detailed enough. The separated contacts still need to be screened manually for a second time. In addition, the above-mentioned comparative cases also lack the function of automatic screening and classification of contacts of different types and sizes. This not only easily prolongs the contact screening time, but also has low screening efficiency and high labor intensity for workers. It also lacks the ability of automatic screening and classification, which reduces the overall scope of use of the device.

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The utility model provides Figure 1-5 The contact automatic screening and classification device shown includes a body 1 for carrying a contact screening assembly;

[0029] A miscellaneous material port 5 is provided on the outside of the machine body 1 and is used to discharge miscellaneous materials in the screening process. A fixing bolt 6 is passed through the outside of the machine body 1. One end of the fixing bolt 6 is movably connected to a coarse screen filter 7. A contact discharge port 8 is provided on one side of the coarse screen filter 7. A discharge plate 9 is fixedly installed on the outside of the contact discharge port 8.

[0030] The middle screen filter 10 is fixedly installed below the coarse screen filter 7 and is used for secondary screening of the contacts, and a fine screen filter 11 is arranged below the middle screen filter 10;

[0031] A small hydraulic cylinder 12 is arranged on the outside of the body 1 and is used to push the contacts on the screening net. The small hydraulic cylinder 12 is internally movably connected with a small hydraulic rod 13. A material discharge push plate 14 is fixedly installed at one end of the small hydraulic rod 13. The material discharge push plate 14 pushes the contacts out of the contact discharge port 8 to complete the classified discharge. This coordinated use not only meets the purpose of automatic screening and classification of different types and sizes, but also expands the use scope of the device, reduces the manpower loss caused by manual operation, and improves the screening efficiency of the contacts.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, a support frame 2 is fixedly installed on the outside of the body 1, a vibration motor 3 is arranged inside the support frame 2, and a vibration rod 4 is fixedly installed on the outside of the vibration motor 3. The two groups of vibration motors 3 drive the vibration rod 4 to make the body 1 vibrate synchronously to complete the screening work of the contacts by the three groups of filters. The coarse screen filter 7 is threadedly connected to the body 1, and the fixing bolts 6 are evenly distributed on the body 1. When the body 1 shakes, the contacts that enter the body 1 first pass through the coarse screen filter 7 to leave large contacts, and then pass through the medium screen filter 10 to screen out medium contacts. Finally, under the screening of the fine screen filter 11, the small contacts and miscellaneous materials are separated. In this way, the contacts are classified and screened into three categories, thereby increasing the screening intensity of the contacts.

[0033] like Figure 1 , Figure 4 and Figure 5 As shown, the material discharge push plate 14 is movably connected to the body 1, and the small hydraulic rod 13 is symmetrically arranged with the central axis of the material discharge push plate 14. The overall structure of the small hydraulic rod 13 is simple and easy to operate. If a fault occurs, it is also convenient for maintenance personnel to carry out maintenance in time to ensure the normal operation of the device. A fixing frame 15 is fixedly installed on the top of the body 1, and a material discharge hopper 16 is fixedly installed inside the fixing frame 15. A material discharge port 17 is opened at the bottom of the material discharge hopper 16. There is no need to feed materials into the body 1 all the time. Materials can be directly fed into the material discharge hopper 16 in batches, so that the material discharge hopper 16 can complete the automatic material discharge work. The outside of the material discharge port 17 passes through a fixed threaded rod 18, and a spacer closing plate 19 is fixedly installed on the outside of the fixed threaded rod 18. The fixed threaded rod 18 is twisted to adjust the angle of the spacer closing plate 19 in the material discharge port 17, thereby controlling the speed at which the contact enters the body 1 from the material discharge port 17.

[0034] The working principle of the utility model is as follows: firstly, the external power supply is turned on, and the contacts that need to be screened are taken out, and the switch of the vibration motor 3 is turned on first, and the vibration rod 4 is driven by two sets of vibration motors 3 to make the machine body 1 vibrate synchronously, so as to facilitate the three sets of filter screens to screen the contacts, and then an appropriate amount of contacts are put into the lower hopper 16, and then the fixed threaded rod 18 is twisted to adjust the angle of the interval closing plate 19 in the discharge port 17, so as to control the speed at which the contacts enter the machine body 1 from the discharge port 17, so that the device can better meet the contact automatic discharge and screening work, and then the contacts entering the machine body 1 are shaken by the machine body 1, and the large contacts are first passed through the coarse screen filter 7 to leave the large contacts, and then the medium contacts are screened out through the medium screen filter 10, and the small contacts are separated from the sundries under the screening of the fine screen filter 11, and then the sundries pass through the fine screen filter 11 and flow out from the sundries port 5, so that the contacts are classified and screened into three categories, increasing The screening strength of the contacts is improved, so that contacts of different sizes can be completely separated. Then, the contacts remaining on the filter screen can turn on the switch of the small hydraulic cylinder 12 to drive the power source of the hydraulic pump. The hydraulic pump presses the hydraulic oil into the small hydraulic cylinder 12. Driven by the small hydraulic cylinder 12, the contacts are pushed out from the contact discharge port 8 through the unloading push plate 14 to complete the classification and unloading of the contacts. At this time, the operator only needs to use a container to collect the classified contacts under the discharge plate 9 and continue to feed them into the unloading hopper 16 to continue the automatic screening of the contacts. Finally, after completing the installation and use of all the automatic screening and classification devices for contacts according to the above operations, turn off the switch of the vibration motor 3 and the switch of the small hydraulic cylinder 12. If not used for a long time, cut off the external power supply. The model of the small hydraulic cylinder 12 is: DR-208500. In this way, the use process of the automatic screening and classification device for contacts is completed.

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that 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.
