Description

Technical Field

[0001] This utility model relates to the field of electromechanical equipment technology, and in particular to a linear rotary actuator. Background Technology

[0002] Linear rotary motors, as integrated drive devices that can simultaneously achieve linear and rotary motion, are widely used in various fields such as electronic manufacturing, precision assembly, and automated logistics due to their core advantages such as compact structure, high motion precision, and fast response speed. Especially in the surface mount technology (SMT) process for electronic components, they can accurately complete the picking, positioning, and mounting of components, making them one of the key pieces of equipment for improving production efficiency.

[0003] In precision manufacturing scenarios such as electronic component mounting, the pick-up and placement of certain special materials, such as low-temperature solder components and adhesive components, often require targeted heating treatment to ensure adhesion stability during subsequent mounting processes. However, currently used traditional suction cup assemblies generally lack integrated heating functions, failing to enhance solder activity or adhesive tack through heating. This results in insufficient adhesion between the material and the nozzle, affecting mounting yield. While some linear rotary motors with heating capabilities typically preheat the material or mounting area using independent heating devices, their temperature control lag prevents localized temperature control at the nozzle, increasing the likelihood of overheating leading to material damage or underheating resulting in poor adhesion.

At the same time, since the side of the heating module away from the mounting assembly is set as a heat-conducting surface, surface contact between the adsorption component and the heating module is achieved, reducing heat loss from the heating module and facilitating temperature control of the adsorption component to further improve the adsorption effect on materials.

[0036] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0037] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0038] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0039] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0040] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0041] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0042] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0043] Combination Figures 1 to 5 As shown, the linear rotary actuator in this embodiment can improve the accuracy of temperature control at the adsorption element 424, ensuring the adsorption effect on the material. Specifically, the linear rotary actuator includes a housing 100, a linear motion component 200, a rotary motion component 300, and a heating adsorption mechanism 400; the linear motion component 200 is disposed in the housing 100; the rotary motion component 300 is driven to the linear motion component 200, and the linear motion component 200 is used to drive the rotary motion component 300 to reciprocate along the A direction; the heating adsorption mechanism 400 includes a mounting component 410 and an adsorption component 420, the mounting component 410 is driven to the rotary output shaft in the rotary motion component 300, and the adsorption component 420 includes a heating module 421 and an adsorption element 424, the adsorption element 424 is disposed on the side of the heating module 421 away from the mounting component 410, and can be in air communication with the rotary output shaft, wherein the side of the heating module 421 away from the mounting component 410 is set as a heat-conducting surface.

[0044] Since the adsorption element 424 is connected to the side of the heating module 421 facing away from the mounting assembly 410, and the side of the heating module 421 facing away from the mounting assembly 410 is set as a heat-conducting surface, this arrangement not only achieves the integrated arrangement of the heating module 421 and the adsorption element 424, but also ensures that the heating module 421 heats the adsorption element 424 during operation, thus maintaining the activity of the solder or the stickiness of the adhesive when the adsorption element 424 adsorbs materials, thereby ensuring the adsorption effect on the materials. At the same time, since the side of the heating module 421 facing away from the mounting assembly 410 is set as a heat-conducting surface, surface contact between the adsorption element 424 and the heating module 421 is achieved, reducing the heat loss of the heating module 421 and facilitating temperature control of the adsorption element 424, thereby further improving the adsorption effect on the materials.

[0045] In addition, to further improve the temperature transfer effect and reduce heat loss, the heat-conducting surface is set as a metal surface in this embodiment.

[0046] Furthermore, the adsorption assembly 420 also includes a first temperature sensor 422 and a second temperature sensor 423. The first temperature sensor 422 is disposed on the heating module 421, and the second temperature sensor 423 is disposed on the adsorption element 424. Both the first temperature sensor 422 and the second temperature sensor 423 are communicatively connected to the heating module 421.

[0047] The first temperature sensor 422 senses the temperature at the heating module 421 to monitor the temperature stability of the heating module 421, thereby ensuring that the temperature of the adsorption element 424 is relatively stable. The second temperature sensor 423 senses the temperature at the adsorption element 424. If the temperature at the adsorption element 424 is higher or lower than the target value, the second temperature sensor 423 sends an adjustment signal to the heating module 421. The heating module 421 adjusts the heating power in real time, thereby realizing the adjustment of the temperature at the adsorption element 424 and ensuring precise control of the temperature at the adsorption element 424, so as to further improve the adsorption effect on the material.

[0048] Preferably, the heating module 421 includes a heat-conducting element 4211 and a heating element 4212. The heat-conducting element 4211 is detachably connected to the mounting assembly 410. The heating element 4212 and the first temperature sensor 422 are both disposed in the heat-conducting element 4211. The adsorption element 424 is connected to the side of the heat-conducting element 4211 away from the mounting assembly 410.

[0049] Combination Figures 1 to 3 and Figure 5 As shown, since the adsorption element 424 is directly connected to the side of the heating element 4212 facing away from the mounting assembly 410, when the heating element 4212 releases heat during operation, the heat can be directly transferred to the adsorption element 424 through the heat-conducting element 4211, thereby improving the heat transfer efficiency. Since the heat-conducting element 4211 is detachably connected to the mounting assembly 410, when the heating element 4212 malfunctions, the heating power changes, or the adsorption requirements change, different heating modules 421 can be replaced to meet the actual needs without replacing the entire heating and adsorption mechanism 400. Furthermore, since both the heating element 4212 and the first temperature sensor 422 are housed within the heat-conducting element 4211, this not only prevents damage to the heating element 4212 and the first temperature sensor 422 from contact with external components, but also eliminates the influence of external dust, airflow, etc., on the detection accuracy of the first temperature sensor 422, thereby ensuring heating and temperature control effects.

[0050] In this embodiment, the heat-conducting element 4211 is configured as a heat-conducting copper pillar with multiple cavities, and the heating element 4212 and the first temperature sensor 422 are respectively disposed in two independent cavities. The heat-conducting copper pillar can quickly transfer the heat of the heating element 4212 to the adsorption element 424, improving the heat transfer speed and efficiency. By disposing of the heating element 4212 and the first temperature sensor 422 in two independent cavities, the high temperature of the heating element 4212 during operation can be prevented from directly affecting the monitoring accuracy of the first temperature sensor 422, and electrical interference between the heating element 4212 and the first temperature sensor 422 can be avoided, thereby further improving the accuracy of temperature control at the adsorption element 424. The heating element 4212 is configured as a high-temperature ceramic heating rod. Because the high-temperature ceramic heating rod has high temperature resistance, it can be adapted to higher heating requirements, thereby increasing the adsorption range of the adsorption component 424. Because the high-temperature ceramic heating rod has good thermal conductivity, the heat generated by its own operation can be quickly transferred to the adsorption component 424 through the heat conduction component 4211, thereby reducing heat loss during the heat transfer process. At the same time, the high-temperature ceramic heating rod can achieve high power output in a small volume, reducing the overall volume of the heating module 421 while meeting the heating requirements of the adsorption component 424.

[0051] Meanwhile, the side of the heat-conducting component 4211 facing away from the mounting assembly 410 is configured as a heat-conducting disk, and along the axial direction of the heat-conducting component 4211, the cross-sectional area of ​​the heat-conducting disk is smaller than the cross-sectional area of ​​the adsorption component 424, but larger than the cross-sectional area of ​​the adsorption hole on the adsorption component 424.

[0052] The side of the heat-conducting plate facing away from the mounting assembly 410 is designated as the heat-conducting surface. Along the axial direction of the heat-conducting element 4211, the cross-sectional area of ​​the heat-conducting plate is smaller than that of the adsorption element 424 to prevent excessive heat loss from the heat-conducting surface due to an excessively large cross-sectional area of ​​the heat-conducting plate. The cross-sectional area of ​​the heat-conducting plate is larger than that of the adsorption holes on the adsorption element 424 to prevent uneven heat transfer to the adsorption element 424 and adsorption holes due to an insufficiently small cross-sectional area of ​​the heat-conducting plate, which would affect the adsorption effect. To further improve the heat transfer effect, in this embodiment, the heat-conducting element 4211 is made of metal.

[0053] In other embodiments, the heat-conducting component 4211 can also be adapted to aluminum alloy, copper-tungsten alloy, aluminum nitride ceramic, etc., according to actual needs, and is not limited to the heat-conducting copper pillar in this embodiment. The heating component 4212 can also be adapted to micro PTC heater, armored heating wire, thin-film resistance heater, carbon fiber heating tube, etc., according to actual needs, and is not limited to the high-temperature ceramic heating rod in this embodiment.

[0054] Preferably, the heating module 421 further includes a male socket 4213 and a male pin 4214. The heat-conducting element 4211 has a plug-in portion on the side away from the adsorption element 424 that can be plugged into the mounting assembly 410. The male socket 4213 is disposed in the heat-conducting element 4211, and the male pin 4214 is disposed in the male socket 4213 and extends towards the plug-in portion. The heating element 4212 is connected to the side of the male socket 4213 away from the male pin 4214. When the plug-in portion is plugged into the mounting assembly 410, the male pin 4214 is plugged into and connected to the female pin 4101 in the mounting assembly 410.

[0055] Combination Figure 2 , Figure 3 and Figure 5 As shown, by connecting the male pin 4214 and the female pin 4101, electrical connection can be achieved between the heating element 4212, the first temperature sensor 422, and the second temperature sensor 423, improving the assembly efficiency of the heating module 421 and ensuring its performance. Simultaneously, when the connector is inserted into the mounting assembly 410, precise connection between the male pin 4214 and the female pin 4101 can be achieved, avoiding poor contact or intermittent connections that may occur with manual wiring, thus ensuring the stability of the connection between the heating module 421 and the mounting assembly 410. Furthermore, placing the male socket 4213, male pin 4214, heating element 4212, and first temperature sensor 422 on the heat-conducting component 4211 further enhances the integration of the heating module 421, facilitating its disassembly, assembly, and replacement.

[0056] Preferably, the mounting assembly 410 includes a heat sink 411, which has a socket for inserting a connector. A female pin 4101 is disposed in the heat sink 411 and extends into the socket. A plurality of heat sink fins 4111 are disposed on the peripheral wall of the heat sink 411.

[0057] Combination Figure 2 and Figure 5 As shown, the female pin 4101 is disposed within the heat sink 411 via the female socket 4102. By providing the heat sink 411, the heat transferred from the heat conductor 4211 to the mounting assembly 410 can be dissipated, reducing the impact of heat on other components in the mounting assembly 410 and lowering the probability of deformation or decreased precision of the rotating motion assembly 300 components under the influence of heat. Furthermore, by providing a insertion slot on the heat sink 411, the heat conductor 4211 is guided to accurately and stably insert into the mounting assembly 410, improving ease of assembly and disassembly. To further enhance the heat dissipation effect of the heat sink 411, multiple heat dissipation fins 4111 are also provided on the peripheral wall of the heat sink 411. In this embodiment, the number and specific shape of the heat dissipation fins 4111 are not limited.

[0058] Furthermore, the mounting assembly 410 also includes a heat insulation cylinder 412 and an electric slip ring 413. The rotating end of the electric slip ring 413 is sleeved on the rotary output shaft. The heat insulation cylinder 412 is connected to the side of the heat sink 411 away from the insertion slot and is drively connected to the rotary output shaft. By setting the heat insulation cylinder 412, when there is still residual heat on the heat sink 411, the heat insulation cylinder 412 can isolate the residual heat of the heat sink 411, preventing heat from being conducted to the force sensor 231 inside the housing 100. This avoids reducing the service life of the force sensor 231 and affecting the accuracy of the force sensor 231, thereby ensuring the performance and accuracy of the linear rotary actuator. The connection lines of the heating element 4212, the first temperature sensor 422, and the second temperature sensor 423 are routed from inside the heat sink 411 and the heat insulation cylinder 412. By setting an electric slip ring 413, and the fixed end of the electric slip ring 413 is set inside the rotating motion assembly 300, the internal wiring is realized. When the rotating output shaft drives the heat insulation cylinder 412 to rotate, the connection lines are prevented from getting tangled, thus ensuring the electrical connection stability of the heating element 4212, the first temperature sensor 422, and the second temperature sensor 423.

[0059] Preferably, the linear motion assembly 200 includes a linear drive motor 210, a guide module 220, and a connector 230; the guide module 220 is movably disposed on the housing 100, the linear drive motor 210 is disposed on the housing 100, the linear output shaft of the linear drive motor 210 extends and retracts along the A direction and is connected to the guide module 220, the connector 230 is connected to the guide module 220, the rotary motion assembly 300 is connected to the connector 230, and a force sensor 231 is disposed between the connector 230 and the guide module 220.

[0060] Because a force sensor 231 is installed between the connector 230 and the guide module 220, and the force sensor 231 is communicatively connected to the linear drive motor 210, the force sensor 231 can monitor in real time the contact force between the adsorption component 424 and the material during linear reciprocating motion along direction A. This includes the contact force corresponding to the suction force during material pickup, the pressure during mounting, etc. When the contact force exceeds a set value, the force sensor 231 sends a force signal to the linear drive motor 210, which then adjusts the extension / retraction of the linear output shaft in a timely manner to avoid material damage during mounting. Furthermore, by setting the guide module 220, the heating adsorption mechanism 400 is ensured to always reciprocate along a predetermined path, thereby reducing the probability of mounting position deviation during mounting.

[0061] Furthermore, the connector 230 and the guide module 220 are respectively provided with a first abutting part 232 and a second abutting part 233 on the side close to each other. One of the first abutting part 232 and the second abutting part 233 is provided as an abutting groove, and the other is provided as an abutting protrusion. There is an avoidance gap between the sidewalls of the abutting groove and the abutting protrusion.

[0062] Combination Figure 4 As shown, in this embodiment, the side of the connector 230 near the guide module 220 is provided with an abutment groove, and correspondingly, the guide module 220 is provided with an abutment protrusion. When the contact force between the connector 230 and the guide module 220 is greater than the range of the force sensor 231, the abutment groove and the abutment protrusion abut against each other, preventing relative displacement between the connector 230 and the guide module 220, and preventing the force sensor 231 from being damaged or malfunctioning due to excessive abutment force being transmitted to it. Furthermore, since there is a clearance gap between the abutment groove and the abutment protrusion, when the linear rotary actuator is in normal operation, the clearance gap can prevent the abutment groove and the abutment protrusion from abutting against each other, thereby ensuring the operating effect of the linear rotary actuator.

[0063] The number of force sensors 231 can be adjusted according to actual needs. In this embodiment, two force sensors 231 are provided, which are respectively located on both sides of the abutment groove and the abutment protrusion. The two force sensors 231 cooperate with each other to further avoid material damage during the mounting process.

[0064] Preferably, the guide module 220 includes a mounting plate 221 and a guide rail 222. The guide rail 222 is disposed on the mounting plate 221 and extends in the A direction. The guide rail 222 is slidably engaged with the guide groove in the housing 100. The mounting plate 221 is drively connected to the linear output shaft.

[0065] By sliding the guide rail 222 with the guide groove, the stability of the mounting plate 221 when it reciprocates along the A direction is ensured, reducing the probability of the mounting plate 221 shifting or shaking during the movement, thereby reducing the positioning error of the adsorption component 424 when adsorbing materials.

[0066] In addition, in this embodiment, a grating seat 224 is provided on the side of the mounting plate 221 near the linear output shaft, and a grating ruler is correspondingly provided on the housing 100. During the reciprocating motion of the mounting plate 221 along the A direction, the grating seat 224 and the grating ruler cooperate with each other to further ensure the extension and retraction accuracy of the linear output shaft and improve the adsorption accuracy and mounting accuracy of the adsorption component 424 on the material.

[0067] Preferably, the guide module 220 further includes a reset member 223, which is disposed opposite to the connector 230 in the guide module 220.

[0068] In this embodiment, the reset element 223 is set as a magnetic spring. When the linear rotary actuator is running, the linear motion component 200 drives the rotary motion component 300 and the heating and adsorption mechanism 400 to reciprocate along direction A. The linear motion component 200 needs to bear the load of the rotary motion component 300 and the heating and adsorption mechanism 400. If the linear rotary actuator is set vertically, that is, when direction A is up and down, when the linear rotary actuator suddenly loses power, the magnetic spring can balance the gravity of the rotary motion component 300 and the heating and adsorption mechanism 400, preventing the rotary motion component 300 and the heating and adsorption mechanism 400 from falling freely, thereby preventing the material from being damaged.

[0069] In this embodiment, the specific structures of the rotary motion component 300, the linear drive motor 210, and the slip ring 413 refer to the prior art and will not be described in detail here.

[0070] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
