Description

Technical Field

[0001] This utility model relates to the field of linear motor technology, and in particular to a self-cooling circulating linear motor. Background Technology

[0002] A linear motor is a transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism. It can be regarded as a rotary motor cut radially and unfolded into a plane. Linear motors are divided into flat linear motors, U-shaped linear motors and tubular linear motors.

[0003] A search revealed a linear motor with publication number CN214480218U, comprising a rail beam, a slider module slidably connected to the rail beam, a mover module mounted on the slider module, a detection module, a stator module mounted on the rail beam and correspondingly arranged with the mover module, and a fixing module mounted on the rail beam and connected to the stator module. The rail beam has grooves along its length, and receiving platforms are formed at intervals between these grooves. Extrusion platforms, corresponding to the receiving platforms, are formed on the inner walls of both sides of the rail beam. The stator module is mounted on the receiving platforms and abuts against the extrusion platforms. This invention solves the problems of traditional linear motor modules having simple structures, complex and cumbersome stator module installation steps, and being prone to loosening and having poor stability.

[0004] The linear motor in the disclosed patent generates heat in both the moving part and the stator during use. Excessive heat will affect the working quality and service life. Current heat dissipation methods usually involve adding external heat dissipation structures, which take up a lot of space, are inconvenient to use, and are too expensive. Utility Model Content

[0005] In response to the existing patents, in order to solve the problem that both the mover and stator of a linear motor generate heat during use, and that excessive heat will affect the working quality and service life, the current heat dissipation method usually involves adding an external heat dissipation structure, which takes up a lot of space, is inconvenient to use, and is too expensive. This utility model provides a self-cooling circulation linear motor.

[0006] The technical solution adopted in this utility model is: a self-cooling circulating linear motor, comprising:

[0007] The motor body includes a base plate, a stator assembly and guide rail mounted on the top of the base plate, a movable seat slidably connected to the top of the guide rail, a mover mounted on the bottom of the movable seat, and a drag chain mounted on one side of the movable seat.

[0008] The self-cooling component is mounted on the movable base and is used to dissipate heat generated in the stator and the moving part.

[0009] The self-cooling assembly includes a stator heat dissipation structure installed at the bottom of the movable base and a mover heat dissipation structure installed on the movable base.

[0010] Furthermore, the stator heat dissipation structure includes a first heat dissipation channel formed on the movable base and a grid guide plate installed at the bottom of the movable base.

[0011] Furthermore, the first heat dissipation channel includes a first air inlet on both sides of the movable seat, a first air outlet on the bottom of the movable seat, and a first channel installed between the first air inlet and the first air outlet. The diameter of the first air inlet is twice the diameter of the first air outlet, the grille guide plate is inclined at 15 degrees, and the grille guide plate cooperates with the first air outlet.

[0012] Furthermore, the heat dissipation structure of the moving element includes a heat-conducting plate installed inside the movable base and a second heat dissipation channel opened on the movable base. The second heat dissipation channel is located at the top of the heat-conducting plate, and the moving element is installed at the bottom of the heat-conducting plate.

[0013] Furthermore, the second heat dissipation channel includes a second air inlet on both sides of the movable seat, a second air outlet on the top of the movable seat, and a second channel installed between the second air inlet and the second air outlet. The diameter of the second air inlet is 1.8 times the diameter of the second air outlet, and the second channel is located on the top of the heat-conducting plate.

[0014] Furthermore, both the first and second air inlets are equipped with electrostatic filters, and the inner walls of both the first and second channels are lined with a layer of sound-absorbing material.

[0015] The beneficial effects of this utility model are:

[0016] When the motor body is working, the moving base will reciprocate. Air enters the first and second channels through the first and second air inlets. The diameter of the first air inlet is twice the diameter of the first air outlet, and the diameter of the second air inlet is 1.8 times the diameter of the second air outlet. The interface between the first and second channels is tapered, and the airflow is accelerated by utilizing the Venturi effect. The airflow is discharged from the first and second air outlets. The airflow from the first air outlet is guided to the stator assembly by the grid guide plate to dissipate heat from the stator assembly. The heat of the mover is introduced into the moving base through the heat conduction plate. When the airflow passes through the second channel, it carries away the heat, which in turn dissipates heat from the mover. No additional cooling structure is needed. The motor body completes the self-cooling cycle by working. It is low in cost and does not take up extra space, making it highly practical. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0028] To address the problems existing in the background art, this application proposes the following technical solution:

[0029] A self-cooling circulating linear motor includes: a motor body 1 and a self-cooling component 2;

[0030] The motor body 1 includes a base plate 101, a stator assembly 102 and a guide rail 103 mounted on the top of the base plate 101, a movable seat 104 slidably connected to the top of the guide rail 103, a mover 105 mounted on the bottom of the movable seat 104, and a drag chain 106 mounted on one side of the movable seat 104.

[0031] like Figure 1-4 As shown, the self-cooling component 2 is installed on the movable base 104. The self-cooling component 2 is used to dissipate heat generated in the stator and the mover 105.

[0032] The self-cooling component 2 includes a stator heat dissipation structure 201 installed at the bottom of the movable base 104 and a mover heat dissipation structure 202 installed on the movable base 104. The stator heat dissipation structure 201 includes a first heat dissipation channel 2011 opened on the movable base 104 and a grid guide plate 2012 installed at the bottom of the movable base 104.

[0033] Furthermore, the first heat dissipation channel 2011 includes a first air inlet 3 on both sides of the movable seat 104, a first air outlet 4 at the bottom of the movable seat 104, and a first channel 5 installed between the first air inlet 3 and the first air outlet 4. The diameter of the first air inlet 3 is twice the diameter of the first air outlet 4. The grille guide plate 2012 is inclined at 15 degrees and cooperates with the first air outlet 4. The first heat dissipation channel 2011 uses the Venturi effect to accelerate the airflow.

[0034] Furthermore, the mover heat dissipation structure 202 includes a heat-conducting plate 2021 installed inside the movable base 104 and a second heat dissipation channel 2022 opened on the movable base 104. The second heat dissipation channel 2022 is located at the top of the heat-conducting plate 2021, and the mover 105 is installed at the bottom of the heat-conducting plate 2021.

[0035] Furthermore, the second heat dissipation channel 2022 includes a second air inlet 6 on both sides of the movable base 104, a second air outlet 7 on the top of the movable base 104, and a second channel 8 installed between the second air inlet 6 and the second air outlet 7. The diameter of the second air inlet 6 is 1.8 times the diameter of the second air outlet 7. The second channel 8 is located on the top of the heat conduction plate 2021. The second heat dissipation channel 2022 utilizes the Venturi effect to accelerate airflow.

[0036] Furthermore, both the first air inlet 3 and the second air inlet 6 are equipped with electrostatic filters 9, and the inner walls of the first channel 5 and the second channel 8 are covered with sound-absorbing material layers 10, specifically polyurethane.

[0037] Working principle: When the motor body 1 is working, the moving base 104 will reciprocate. During the reciprocating motion, air enters the first channel 5 and the second channel 8 through the first air inlet 3 and the second air inlet 6. Since the diameter of the first air inlet 3 is twice the diameter of the first air outlet 4, and the diameter of the second air inlet 6 is 1.8 times the diameter of the second air outlet 7, the interface of the first channel 5 and the second channel 8 are both tapered. The airflow is accelerated by the Venturi effect. The airflow is discharged from the first air outlet 4 and the second air outlet 7. The airflow from the first air outlet 4 is guided to the stator assembly 102 by the grid guide plate 2012 to dissipate heat from the stator assembly 102. The heat of the mover 105 is introduced into the moving base 104 through the heat conduction plate 2021. When the airflow passes through the second channel 8, it carries away the heat and dissipates heat from the mover 105. No additional cooling structure is needed. The motor body 1 completes the cycle of self-cooling by working. It is low in cost and does not occupy extra space, making it highly practical.
