Description

Technical Field

[0001] The utility model relates to the field of servo drivers, in particular to an AC servo driver with a dustproof structure. Background Art

[0002] A servo drive, also known as a "servo controller" or "servo amplifier", is a controller used to control a servo motor. Its function is similar to that of a frequency converter on an ordinary AC motor. It is part of a servo system and is mainly used in high-precision positioning systems. Generally, the servo motor is controlled by three methods: position, speed and torque to achieve high-precision positioning of the transmission system. It is a high-end product of transmission technology. However, the existing fully digital AC servo drive has the disadvantage that ventilation and heat dissipation slots are generally provided on the front and rear sides of the drive, and there is generally no dust-proof structure at the ventilation and heat dissipation slots, which makes it easy for dust to enter and accumulate inside the servo motor. Over time, it will affect the normal operation of the servo drive and reduce its overall service life. Therefore, application number: CN202022135365.9 discloses a fully digital AC servo drive, including a base of a servo drive, a main body of the servo drive, a dust-proof structure for dust-proofing the inside of the servo drive, a quick fixing structure for quickly fixing the dust-proof structure, and an auxiliary wiring structure for assisting the wiring of the main body. The main body is fixedly installed on the upper end surface of the base, and a plurality of ventilation slots for ventilation and heat dissipation are provided on the front and rear sides of the main body, and the dust-proof structure is installed at the ventilation slots on the front and rear sides of the main body. The utility model can effectively carry out dust prevention treatment on the ventilation slots of the servo driver, and the dust prevention structure is convenient for disassembly and cleaning. At the same time, it is convenient for more regular routing of multiple wirings of the servo driver, avoiding the entanglement of the lines, reducing safety hazards, and facilitating the subsequent disassembly and replacement of individual lines, and has high practicality.

[0003] However, the above scheme still has certain defects. The inventor has found through research that in the above scheme, a dustproof net is set on one side of the ventilation slot to filter the air entering the inside of the main body, so as to prevent dust from entering the inside of the main body through the ventilation slot and affecting the normal working efficiency of the main body. When a lot of dust accumulates on the dustproof net and causes blockage, it needs to be removed for cleaning. During this process, the ventilation slot loses the protection of the dustproof net, which may cause dust and foreign matter to enter the inside of the main body through the ventilation slot. The accumulation formed during long-term use will still affect the normal working effect of the main body, resulting in certain limitations in use.

[0004] How to invent an AC servo drive with a dustproof structure to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0005] In order to make up for the above deficiencies, the utility model provides an AC servo driver with a dust-proof structure, which aims to improve the filtering of the air entering the interior of the main body by setting a dust-proof net on one side of the ventilation slot, so as to prevent dust from entering the interior of the main body through the ventilation slot and affecting the normal working efficiency of the main body. When a lot of dust accumulates on the dust-proof net and causes blockage, it needs to be removed for cleaning. In this process, the ventilation slot loses the protection of the dust-proof net, which may cause dust and foreign matter to enter the interior of the main body through the ventilation slot. The accumulation formed during long-term use will still affect the normal working effect of the main body, thereby leading to certain limitations in use.

[0006] The utility model is implemented as follows: an AC servo driver with a dustproof structure, comprising a servo driver body, a heat dissipation groove is provided on one side surface of the servo driver body, a dustproof mechanism is arranged at a position corresponding to the heat dissipation groove on one side surface of the servo driver body, the dustproof mechanism comprises an outer cover, the outer cover is fixedly connected to one side surface of the servo driver body and is located outside the heat dissipation groove, a through groove is provided on one side surface of the outer cover, a filter is fixedly installed between the inner walls around the through groove, sliding grooves are provided on the inner walls on both sides of the outer cover, sliders are slidably installed in the two sliding grooves, a brush roller is rotatably installed between the opposite side surfaces of the two sliders, and the brush roller is connected to a driving member so as to be independently lifted and displaced relative to the outer cover.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 4 The utility model provides a technical solution: an AC servo driver with a dustproof structure, comprising a servo driver body 1, a heat dissipation groove 101 is provided on one side surface of the servo driver body 1, a dustproof mechanism 2 is arranged at a position corresponding to the heat dissipation groove 101 on one side surface of the servo driver body 1, the dustproof mechanism 2 comprises an outer cover 201, the outer cover 201 is fixedly connected to one side surface of the servo driver body 1 and is located outside the heat dissipation groove 101, a through groove 202 is provided on one side surface of the outer cover 201, a filter screen 203 is fixedly installed between the inner walls around the through groove 202, slide grooves 204 are provided on the inner walls on both sides of the outer cover 201, sliders 205 are slidably installed in the two slide grooves 204, a brush roller 206 is rotatably installed between the opposite side surfaces of the two sliders 205, and the brush roller 206 is connected to the driving member to perform independent lifting and displacement relative to the outer cover 201.

[0023] See also Figures 2 to 4 The driving member includes two L-shaped connecting frames 207, one end of the two L-shaped connecting frames 207 is fixedly connected to the corresponding sliders 205, and the other ends of the two L-shaped connecting frames 207 are fixedly connected through a connecting plate 208. One end of a driving screw 209 is rotatably installed on the upper surface of the connecting plate 208, and the driving screw 209 is threadedly connected to a threaded hole 210 opened on the inner wall of the top of the outer cover 201.

[0024] Because the driving screw 209 is threadedly connected to the threaded hole 210 and one end thereof is rotatably connected to the upper surface of the connecting plate 208, and the two ends of the connecting plate 208 are connected to the two sliders 205 through the L-shaped connecting frame 207, when the driving screw 209 is rotated, the slider 205 can be driven to slide in the slide groove 204, and the brush roller 206 can be driven to move up and down according to the rotation direction. When the brush roller 206 moves independently relative to the filter 203, the brush of the brush roller 206 contacts the filter 203. Under the influence of friction, the brush roller 206 will also rotate independently relative to the sliders 205 on both sides, so that the dust and foreign matter adhered to the filter 203 are brushed off by the inner side of the filter 203, so as to avoid long-term adhesion causing clogging of the filter 203 and reducing the heat dissipation effect of the servo driver body 1.

[0025] Furthermore, a dirt removal opening is provided at the bottom of the outer cover 201, and a bottom cover 211 is hingedly connected to one side edge of the dirt removal opening. The bottom cover 211 is movably connected to the outer cover 201 via a limiting member.

[0026] The other end of the driving screw 209 extends to the outside of the outer cover 201 through the threaded hole 210 and is fixedly connected to a knob 215 .

[0027] By providing the knob 215 , the driving screw 209 can be rotated more conveniently, thereby providing convenience for use.

[0028] A dirt removal opening is provided at the bottom of the outer cover 201, and a bottom cover 211 is hingedly connected to one side edge of the dirt removal opening. The bottom cover 211 is movably connected to the outer cover 201 through a limiting member.

[0029] When the dust and foreign matter on the filter 203 are swept off, some of them may fall into the outer cover 201. By providing a dirt removal port, the bottom cover 211 can be opened regularly to clean the dust and foreign matter inside the outer cover 201, thereby preventing dust and foreign matter from entering the servo drive body 1 through the heat dissipation slot 101 due to long-term accumulation.

[0030] Furthermore, the limiting member includes four connecting and fixing parts 212 respectively arranged on the bottom ends of the two side surfaces of the outer cover 201 and the two end surfaces of the bottom cover 211. The upper and lower connecting and fixing parts 212 are located on the same side. A through hole is opened on the surface of each connecting and fixing part 212, and a bolt and nut kit 213 is inserted into the upper and lower through holes located on the same side.

[0031] The bottom cover 211 can be stably closed at the dirt removal port by the cooperation of the bolt and nut kit 213 and the connecting fixing parts 212 on both sides. The installation and removal of the bolt and nut kit 213 are also relatively convenient, thereby ensuring that air can only enter the outer cover 201 through the filter 203, thereby improving the overall dustproof effect.

[0032] Furthermore, a storage bin 214 is provided between the through slot 202 and the dirt removal port.

[0033] The storage bin 214 is located between the filter 203 and the dirt removal port. While providing a storage space for dust and foreign matter that falls into the outer cover 201, it can also store and store the brush roller 206 at ordinary times, thereby preventing the brush roller 206 from blocking the filter 203, reducing the air circulation area and reducing the heat dissipation effect of the servo driver body 1.

[0034] Furthermore, the outer cover 201 and the filter screen 203 are both made of stainless steel.

[0035] Stainless steel has relatively high strength and corrosion resistance, so that when the servo driver body 1 is in a relatively complex environment, it can also have a long service life. Secondly, stainless steel also has good thermal conductivity, so it can also use the expanded contact area with the air to assist the servo driver body 1 in heat dissipation.

[0036] Furthermore, the brush material of the brush roller 206 is nylon.

[0037] The nylon material also has a long service life and strong toughness, and can ensure the brushing effect when cleaning the filter 203.

[0038] Working principle: When the servo driver body 1 is working, the heat dissipation slot 101 is used to improve the internal and external air circulation for heat dissipation, and the air entering the servo driver body 1 is filtered through the filter 203, so as to prevent dust and foreign matter in the air from entering the servo driver body 1 and affecting the normal working effect. When there is a lot of dust and foreign matter adhering to the filter 203, the driving screw 209 can be rotated by the knob 215, and the brush roller 206 can be driven by the driving screw 209 to independently lift and displace relative to the filter 203. The brush arranged on the outer wall of the brush roller 206 contacts the inner side of the filter 203. Under the influence of friction, the brush roller 206 will independently rotate the sliders 205 on both sides, so that the filter 203 is brushed from the inside by the brush, so that the dust and foreign matter adhered to the filter 203 fall off to ensure normal air circulation. By arranging the brush roller 206 inside the outer cover 201, the servo drive body 1 can work normally and the filter 203 can be cleaned. It does not cause the filter 203 to be removed when it is blocked and needs to be cleaned, causing dust and foreign matter to enter the servo drive body 1 from the heat sink 101 during the cleaning process, thereby reducing the limitations in use.

[0039] It should be noted that the specific model and specifications of the servo drive body 1 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.

[0040] The power supply and principle of the servo driver body 1 are clear to those skilled in the art and will not be described in detail here.

[0041] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
