[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. According to the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] The terms "first", "second", etc. in this application are used to distinguish different objects rather than to describe a specific order. In addition, the terms "include", "have", and any variations thereof are intended to cover non-exclusive inclusions.

[0024] It should be noted that when a certain element is fixed to another element, it includes directly fixing the element to the other element, or fixing the element to the other element through at least one other element in the middle. When an element is connected to another element, it includes directly connecting the element to the other element, or connecting the element to the other element through at least one other element in the middle.

[0025] This application first proposes a tray driving device, such as Figure 1 to Figure 2 As shown, Figure 1It is a structural schematic diagram of an embodiment of the tray driving device of the present application; Figure 2 yes Figure 1 Schematic side view of the embodiment. The tray driving device is used to drive the tray 01, including a support assembly, a driven wheel 02, a first driving assembly 03, and a transmission assembly 04. The driven wheel 02 is arranged on the support assembly and is arranged corresponding to the tray 01, and is used to drive the corresponding tray 01 to rotate; the first driving assembly 03 provides driving force; the transmission assembly 04 includes a first transmission wheel 41 and a swing arm 42, the first transmission wheel 41 is arranged on the swing arm 42, and the first driving assembly 03 is connected to the first transmission wheel 41 in a transmission connection, and the swing arm 42 is configured to be able to move to a first position where the first transmission wheel 41 is connected to the driven wheel 02 in a transmission connection, and a second position where the first transmission wheel 41 is separated from the driven wheel 02; wherein the swing arm 42 is located at the first position, and the first driving assembly 03 is connected to the driven wheel 02 in a transmission connection through the first transmission wheel 41 to drive the tray 01 to rotate.

[0026] In an application scenario, the driven wheel 02 is set corresponding to the material tray 01, for example, the driven wheel 02 corresponds to the material tray 01 one by one, or one driven wheel 02 corresponds to multiple material trays 01, which is not specifically limited; further, in an application scenario, the material tray driving device may include multiple driven wheels 02, each driven wheel 02 is set corresponding to different multiple material trays 01, so as to realize group control of multiple material trays 01 in different groups. The specific number of material trays and driven wheels is not limited.

[0027] When the material tray 01 needs to discharge or collect materials, the swing arm 42 can be controlled to swing, so that the first transmission wheel 41 is connected to the corresponding driven wheel 02. Under the driving action of the first drive component 03, the first transmission wheel 41 drives the driven wheel 02 to rotate, and the driven wheel 02 drives the material tray 01 to rotate to complete the discharge or collection of materials. The forward or reverse rotation of the material tray 01 can be achieved by adjusting the forward or reverse rotation of the first drive component 03.

[0028] In one application scenario, the swing arm 42 is a mechanical swing arm. The mechanical swing arm can be designed into a mechanical structure with different degrees of freedom according to different needs, so as to achieve more precise and flexible motion control; the mechanical swing arm is usually composed of multiple joints and connecting rods, and can perform various complex movements; during the movement of the mechanical arm, the mechanical swing arm can achieve positioning and posture adjustment in three-dimensional space, so as to complete various different work tasks; through precise control of the mechanical swing arm, high-precision, high-efficiency, and high-quality work requirements can be achieved, thereby improving production efficiency and product quality.

[0029] It should be noted that the material tray driving device of the present application can be used in a 3D printer, and can also be used in other equipment that requires the material tray 01 to rotate, without specific limitation.

[0030] With the continuous development of science and technology, 3D printing technology is becoming more and more mature. 3D printing needs to be completed by a 3D printer. The existing 3D printer needs to complete the material discharge by rotating the material tray 01. Specifically, when the front extruder spins the filament forward, it drives the material tray to rotate. This method easily causes the filament to be pulled, thereby increasing the risk of the filament being torn, which is easy to cause the 3D printer to malfunction and affect the production quality.

[0031] The tray driving device provided in this embodiment provides driving force through the first driving component 03, which can make the tray 01 rotate autonomously when discharging or collecting materials, reduce the risk of the material wire being pulled, and reduce the failure rate of the product; further, the driven wheel 02 is used to drive the corresponding tray 01 to rotate, the first driving component 03 is connected to the first transmission wheel 41, the first transmission wheel 41 is set on the swing arm 42, the swing arm 42 can swing, and when the tray 01 needs to rotate, the swing arm 42 can be controlled to swing so that the first transmission wheel 41 and the corresponding driven wheel 02 are set in transmission, and when the tray 01 does not need to rotate, the swing arm 42 can be controlled to swing so that the first transmission wheel 41 and the corresponding driven wheel 02 are separated, thereby improving the control accuracy of the rotation of the tray 01, and different trays 01 can be controlled to rotate by controlling different driven wheels 02, further improving the control accuracy of the rotation of the tray 01. Therefore, this embodiment can reduce the risk of the material wire being pulled, reduce the failure rate of the product, and improve the control accuracy of the rotation of the tray 01.

[0032] Alternatively, if Figure 1 As shown, the first driving component 03 also includes a driving shaft 05 and a driving wheel 51. The driving shaft 05 is arranged between the driven wheel 02 and the transmission component 04; the driving wheel 51 is arranged on the driving shaft 05, and the driving wheel 51 and the driven wheel 02 are arranged at an interval; wherein, when the swing arm 42 is located at the first position, the driven wheel 02 and the driving wheel 51 are simultaneously connected to the first transmission wheel 41; when the swing arm 42 is located at the second position, the driven wheel 02 and the driving wheel 51 are simultaneously separated from the first transmission wheel 41.

[0033] It should be noted that the driving wheel 51 and the driven wheel 02 are spaced apart, that is, when the swing arm 42 is in the second position, the driven wheel 02 and the driving wheel 51 are separated, there is no transmission connection, and transmission cannot be achieved. In one application scenario, the driving wheel 51 and the driven wheel 02 are spaced apart in the axial direction of the driving shaft 05, and the axial spacing distance is smaller than the axial width of the first transmission wheel 41 in the axial direction of the driving shaft 05, that is, when the swing arm 42 is located at the first position, the first transmission wheel 41 can simultaneously achieve transmission connection with the driven wheel 02 and the driving wheel 51; in another application scenario, the driving wheel 51 and the driven wheel 02 are spaced apart in the axial direction vertical to the driving shaft 05, and when the swing arm 42 is located at the first position, the first transmission wheel 41 can simultaneously achieve transmission connection with the driven wheel 02 and the driving wheel 51; in yet another application scenario, the driving wheel 51 and the driven wheel 02 are spaced apart in the axial direction of the driving shaft 05, and the driving wheel 51 and the driven wheel 02 are spaced apart in the axial direction vertical to the driving shaft 05, and when the swing arm 42 is located at the first position, the first transmission wheel 41 can simultaneously achieve transmission connection with the driven wheel 02 and the driving wheel 51. In summary, when the swing arm 42 is located in the second position, the driven wheel 02 and the driving wheel 51 are separated, there is no transmission connection, and transmission cannot be achieved, and the specific spacing method is not limited.

[0034] Specifically, the first driving component 03 drives the driving shaft 05 to rotate, and the driving shaft 05 drives the driving wheel 51 to rotate. Only when the swing arm 42 is located at the first position, the first transmission wheel 41 can realize transmission between the driving wheel 51 and the driven wheel 02. Therefore, by controlling the position state of the swing arm 41, it is possible to selectively control whether the corresponding driven wheel 02 rotates, and then realize the control of the rotation of the corresponding material tray 01.

[0035] The beneficial effect of the above arrangement is that, when in an application scenario, the material tray driving device includes multiple driven wheels 02, multiple driving wheels 51 corresponding to the driven wheels 02, and multiple swing arms 41 corresponding to the driven wheels 02, a driving shaft 05 and a first driving assembly 03 are provided, and by controlling the position states of different swing arms 41, multiple or one corresponding driven wheels 02 can be selectively controlled to rotate at the same time, thereby selectively controlling the rotation of the corresponding material tray 01. This can reduce the number of parts of the product, reduce costs, and improve assembly efficiency.

[0036] Optionally, the drive shaft 05 is rotatably connected to the support assembly to provide a supporting force for the drive shaft 05 .

[0037] Optionally, the tray driving device also includes a synchronous wheel and a synchronous belt. The first driving component 03 drives the synchronous wheel to rotate, and the synchronous wheel drives the driving shaft 05 to rotate through the synchronous belt. The structure is reliable and simple and easy to install.

[0038] Optionally, the tray driving device further includes a plurality of driven shafts 06, and driven wheels 02 are disposed on the driven shafts 06, and the plurality of driven shafts 06 are disposed one-to-one with the plurality of driven wheels 02, and the driven shafts 06 are in contact with and connected to the tray 01. Specifically, the driven wheels 02 drive the driven shafts 06 to rotate, and the driven shafts 06 are in contact with and connected to the tray 01, and the corresponding tray 01 can be driven to rotate through friction.

[0039] Optionally, multiple driven shafts 06 are coaxially arranged, and adjacent driven shafts 06 are movably connected. This arrangement can ensure that the rotational motions of the multiple driven shafts 06 do not affect each other, and at the same time facilitates power transmission between the multiple driven shafts 06 and the drive shaft 05 and the multiple transmission components 04, thereby improving the ease of assembly of the product.

[0040] Optionally, each driven shaft 06 may correspond to a plurality of material trays 01 , thereby enabling group control of the material trays 01 .

[0041] Optionally, the tray driving device includes a plurality of transmission components 04 and a plurality of driven wheels 02 , and the transmission components 04 and the driven wheels 02 are arranged in a one-to-one correspondence.

[0042] Specifically, multiple transmission components 04 are arranged in a one-to-one correspondence with multiple driven wheels 02, which can make it easier to selectively and individually control the corresponding transmission component 04 to drive the corresponding driven wheel 02 to rotate based on usage needs, and then drive the corresponding driven wheel 02 to rotate; further, since different material trays 01 correspond to different transmission components 04, different material trays 01 can be simultaneously controlled to rotate in different rotation directions, rotation speeds, etc. based on needs, thereby further improving the control accuracy of the drive of the material tray 01.

[0043] In other embodiments, multiple transmission components may be provided, and each transmission component 04 corresponds to multiple driven wheels, that is, each transmission component drives a group of driven wheels, thereby realizing group control of multiple material trays.

[0044] Optionally, the tray drive device includes multiple transmission components 04 and multiple driven wheels 02, and the number of transmission components 04 is less than the number of driven wheels 02, and the multiple driven wheels 02 are arranged at intervals along the first direction X. The tray drive device also includes a sliding component 07, and the sliding component 07 is used to drive the transmission component 04 to move along the first direction X so that the first transmission wheel 41 is connected to the driven wheels 02 at different positions.

[0045] The beneficial effect of the above arrangement is that the multiple driven wheels 02 are arranged at intervals along the first direction X. Since the driving transmission assembly 04 can be driven to move along the first direction X through the sliding assembly 07, there is no need to set the same number of transmission assemblies 04 as the number of driven wheels 02, so as to selectively control the rotation of one or more corresponding driven wheels 02.

[0046] For example, in one application scenario, only one transmission assembly 04 may be provided, and the sliding assembly 07 may be used to realize the selective driving of all driven wheels 02. This embodiment can reduce the number of parts and components, and is flexible and convenient to operate.

[0047] For another example, in other application scenarios, multiple transmission components can be set, the number of transmission components is less than the number of driven wheels, and the sliding component is used to drive multiple first transmission wheels to move in the first direction X respectively, so that the driven wheels at multiple different positions can be selectively driven at the same time; for another example, in other application scenarios, the number of first transmission wheels is not limited, and the width of the first transmission wheel in the first direction X can be set to achieve a first transmission wheel driving two or more adjacent driven wheels at the same time, that is, the first transmission wheel is driven to move in the first direction X by the sliding component, and one first transmission wheel can drive a group of driven wheels to rotate at the same time. If the product is provided with multiple first transmission wheels, multiple groups of driven wheels can be selectively driven to rotate at the same time. Therefore, this embodiment can reduce the number of components and is flexible and convenient to operate.

[0048] In other embodiments, the tray driving device may further include a plurality of sliding components, which are arranged corresponding to the plurality of transmission components to further improve the control convenience and accuracy.

[0049] Optionally, the sliding assembly 07 includes a slide rail 71, a slider and a second drive assembly 08, the slide rail 71 extends along the first direction X and is located on the periphery of the multiple material trays 01; the transmission assembly 04 is arranged on the slider, and the slider is slidably arranged on the slide rail 71; the second drive assembly 08 is connected to the slide rail 71, and is used to drive the slider to slide on the slide rail 71 along the first direction X.

[0050] In one application scenario, when it is necessary to drive the material tray 01 corresponding to the driven wheel 02, the second driving component 08 can be controlled to drive the slider to slide on the slide rail 71, and then drive the transmission component 04 to move to the position of the driven wheel 02, so the swing arm 42 can be controlled to swing so that the first transmission wheel 41 and the driven wheel 02 are transmitted; when it is necessary to drive other material trays 01, the swing arm 42 can be controlled to swing in the opposite direction first, so that the first transmission wheel 41 is separated from the current driven wheel 02, and the slider is driven by the second driving component 08 to slide on the slide rail 71, and then the transmission component 04 is controlled to move along the first direction X to the position of other material trays 01, and the swing arm 42 is controlled to swing again so that the first transmission wheel 41 is transmitted to the driven wheel 02 corresponding to the position.

[0051] The beneficial effect of the above-mentioned arrangement is that there is no need to set up multiple sets of transmission components 04. The driving transmission component 04 can be driven to move along the arrangement direction of multiple driven wheels 02 through the slide rail 71 and the second drive component 08, which makes it easier for the swing arm 42 to swing so that the first transmission wheel 41 and the corresponding driven wheel 02 are transmitted. This embodiment has a simple and reliable structure, is easy to operate, can reduce costs, improve control convenience, and improve product stability and reliability.

[0052] In other embodiments, the transmission assembly may be driven to move in the arrangement direction of the multiple driven wheels by other mechanisms.

[0053] Optionally, the transmission assembly 04 also includes a first bracket 43 and a third drive assembly, and the end of the swing arm 42 away from the first transmission wheel 41 is arranged on the first bracket 43; the third drive assembly is arranged on the first bracket 43, and is used to drive the swing arm 42 to move between the first position and the second position.

[0054] In one application scenario, when it is necessary to drive the material tray 01 to rotate, the first drive component 03 drives the first transmission wheel 41 to rotate, and the third drive component drives the swing arm 42 to swing to the first position, and then can be simultaneously connected to the first transmission wheel 41 and the corresponding driven wheel 02, so that the driven wheel 02 rotates and drives the material tray 01 to rotate.

[0055] The beneficial effect of the above-mentioned arrangement is that the end of the swing arm 42 away from the first transmission wheel 41 is arranged on the first bracket 43, which is beneficial to provide a swing support point for the swing arm 42 and can improve the position stability of the swing arm 42 when swinging; the setting of the third drive component can improve the convenience and control accuracy of controlling the swing of the swing arm 42.

[0056] Optionally, the third driving assembly includes a magnetic member 44, which is mounted on the first bracket 43 and coupled to the swing arm 42, so that the swing arm 42 swings to the first position through magnetic force when the magnetic member 44 is energized.

[0057] In one application scenario, when it is necessary to drive the material tray 01 to rotate, the first drive component 03 drives the first transmission wheel 41 to rotate. At this time, the magnetic part 44 is controlled to generate magnetism, so that the swing arm 42 swings under the action of the magnetic force, and then drives the first transmission wheel 41 and the corresponding driven wheel 02 to transmit, so that the driven wheel 02 rotates and drives the material tray 01 to rotate.

[0058] The beneficial effect of the above arrangement is that the convenience and accuracy of controlling the swing arm 42 to swing between the first position and the second position can be improved by controlling the swing arm 42 to swing between the first position and the second position through the magnetic member 44 .

[0059] Optionally, the swing arm 42 is rotatably connected to the first bracket 43 via a rotating shaft, and the swing arm 42 can rotate around the rotating shaft as the rotation center under the action of the magnetic force of the magnetic member 44, thereby achieving a swinging effect.

[0060] Optionally, the magnetic member 44 is an electromagnet, which can swing the swing arm 42 through magnetic force after being energized, so that the first transmission wheel 41 and the driven wheel 02 are in transmission arrangement.

[0061] Specifically, the electromagnet is composed of a coil and an iron core. When current passes through the coil, the coil generates a magnetic field, magnetizing the iron core, thereby generating a magnetic force. The magnitude and direction of the magnetic force can be adjusted by controlling the magnitude and direction of the current. The mechanical swing arm is placed in the magnetic field of the electromagnet. When the electromagnet is energized, the magnetic field will generate a magnetic force on the swing arm 42, so that the swing arm 42 is subjected to an attractive force or repulsive force in the direction of the magnetic field, thereby causing the swing arm 42 to move. By controlling the magnitude and direction of the current of the electromagnet, the magnitude and direction of the magnetic force can be controlled, thereby achieving precise control of the movement of the swing arm 42. Specifically, when the swing arm 42 needs to move in a certain direction, the magnetic field can be controlled by controlling the current direction and magnitude of the electromagnet so that the swing arm 42 generates a corresponding attractive force or repulsive force, thereby causing the swing arm 42 to move in the target direction. At the same time, optionally, the current of the electromagnet can also be adjusted by monitoring the position and speed of the swing arm 42 to ensure that the swing arm 42 can accurately reach the target position. Therefore, the control method of controlling the swing arm 42 using an electromagnet has the advantages of fast response speed, high control accuracy, and good reliability.

[0062] Optionally, the transmission assembly 04 further includes an elastic member 45 , one end of the elastic member 45 abuts against the swing arm 42 , and the other end of the elastic member 45 abuts against the first bracket 43 , providing a reset force for the swing arm 42 to deviate from the driven wheel 02 .

[0063] In one application scenario, based on the above-mentioned magnetic part 44, the transmission component 04 also includes an elastic part 45. The first drive component 03 drives the first transmission wheel 41 to rotate. The first transmission wheel 41 is connected to the driven wheel 02 to drive the driven wheel 02 to rotate, and then drives the material tray 01 to rotate. When it is no longer necessary to drive the material tray 01 to rotate, the magnetic part 44 can be controlled to lose its magnetism, and the swing arm 42 swings to reset under the action of the elastic part 45, thereby separating the first transmission wheel 41 from the corresponding driven wheel 02 to complete power isolation.

[0064] The beneficial effect of the above arrangement is that by adding the elastic part 45, when there is no need to drive the material tray 01 to rotate, the magnetic part 44 can be directly controlled to cut off the power to achieve the resetting and power isolation of the swing arm 42, without the need for other complex controls (such as changing the magnetic poles of the magnetic part 44), the operation is simple, the structure is simple, and the difficulty and cost of production assembly can be reduced.

[0065] Optionally, the elastic member 45 can be a spring, which generally has high reliability and can provide stable performance for a long time. The spring can be easily integrated with various devices and conveniently installed in various devices without the need for special tools or skills and has low cost, thus saving costs.

[0066] In other embodiments, similar improvements can be made to the tray driving device, which will not be described in detail here.

[0067] Alternatively, in another embodiment, Figure 3 As shown, the third driving assembly includes a second transmission wheel 46 and a second bracket 47. The second transmission wheel 46 is respectively connected to the first driving assembly 03 and the first transmission wheel 41 in transmission connection. The first driving assembly 03 is arranged on the second bracket 47. The rotating shaft of the second transmission wheel 46 is rotationally connected to the second bracket 47 and is arranged in contact with the swing arm 42. The second bracket 47 is provided with a limiting portion 471. The first driving assembly 03 drives the second transmission wheel 46 and the first transmission wheel 41 to rotate, so that the second transmission wheel 46 drives the swing arm 42 to swing to the limiting portion 471 and the first transmission wheel 41 drives the driven wheel.

[0068] It should be noted that the rotating shaft of the second transmission wheel 46 is arranged in contact with the swing arm 42 and can rotate relatively, and there is friction between the rotating shaft of the second transmission wheel 46 and the swing arm 42.

[0069] In one application scenario, the first drive component 03 drives the shaft of the second transmission wheel 46 to rotate.

This design not only does not require multiple sets of transmission assemblies 04, but also does not require structures such as magnetic parts to achieve control of the swing arm 42 and drive of the driven wheel 02. It has a simple structure, reliable and easily available parts, and can improve product reliability and reduce costs.

[0071] The beneficial effect of the above arrangement is that the second transmission wheel 46 is arranged in contact with the swing arm 42, which can drive the swing arm 42 to rotate, and then drive the first transmission wheel 41 to be connected to the corresponding driven wheel, and at the same time, the power transmission from the second transmission wheel 46 to the first transmission wheel 41 and then to the corresponding driven wheel can be completed, and the structure is stable and the parts are simple; further, the rotating shaft of the second transmission wheel 46 is rotatably connected to the second bracket 47, and the second bracket 47 can provide support for the second transmission wheel 46, thereby improving the position stability of the second transmission wheel 46; further, the limiting portion 471 of the second bracket 47 can effectively limit and stop the swing arm 42, thereby improving the accuracy and stability of the transmission connection between the first transmission wheel 41 and the driven wheel.
