[0002] In the production process of inductors, two magnetic cores need to be bonded together. Two positions on the magnetic cores require the application of glue A and glue B by a conveying device. This requires the magnetic cores to be conveyed sequentially from the loading position to two dispensing machines and the unloading position. In related technologies, the conveying device includes a lead screw module and a fixture. The fixture is used to carry the parts. The lead screw module extends along the direction of the loading position, the two dispensing machines, and the unloading position, and can drive the fixture back and forth between the loading position and the unloading position so that the parts on the fixture can pass through the two dispensing machines sequentially for glue application. However, a lead screw module is generally connected to only one fixture, resulting in low conveying efficiency and thus affecting production efficiency. Utility Model Content

[0025] Reference Figure 1 and Figure 3 According to a first aspect embodiment of this application, a conveying device includes: a conveying module 1000, the conveying module 1000 including a first drive assembly 100, a second drive assembly 200, and a fixture 300, the fixture 300 being used to carry a part 600, the first drive assembly 100 being driven and connected to the fixture 300, and being used to drive the fixture 300 to move along a first direction to reciprocate between a loading position and a unloading position, the first drive assembly 100 and the fixture 300 being provided in multiple and corresponding to each other, the multiple first drive assemblies 100 being distributed along the height direction; at least one second drive assembly 200 being provided, the second drive assembly 200 being driven and connected to one of the fixtures 300, and being used to drive the fixture 300 to rise and fall; The conveying module 1000 is provided in multiple ways, and the multiple conveying modules 1000 are distributed along the second direction, and the first direction and the second direction intersect.

[0026] It is understood that, in a specific embodiment, the conveying device of the first aspect embodiment is applied to a dispensing machine, which further includes a loading robot, a first dispensing device, a second dispensing device, and a unloading robot. A first driving assembly 100 drives a fixture 300 to move horizontally along a first direction. A loading position, a first dispensing position, a second dispensing position, and an unloading position are formed along the movement path of the fixture 300. The loading robot is located beside the loading position, the first dispensing device is located beside the first dispensing position, the second dispensing device is located beside the second dispensing position, and the unloading robot is located beside the unloading position. Two conveying modules 1000 are provided, each including two fixtures 300 and a second driving assembly 200. Only one fixture 300 in the same conveying module 1000 is connected to the second driving assembly 200. In summary, the two conveying modules 1000 include a total of four fixtures 300, and each of the two conveying modules 1000 has one fixture 300 that can be raised and lowered. During the production process of part 600, the four fixtures 300 can sequentially pass through the loading position, the first dispensing position, the second dispensing position, and the unloading position. The loading robot loads the empty fixture 300 at the loading position, the first dispensing device dispenses glue to the part 600 in the fixture 300 at the first dispensing position, the second dispensing device dispenses glue to the part 600 in the fixture 300 at the second dispensing position, and the unloading robot unloads the part 600 in the fixture 300 at the unloading position. The first dispensing device and the second dispensing device dispense different glues and dispense glue at different positions on the part 600. Multiple fixtures 300 can be in different positions at the same time, so that the loading robot, the first dispensing device, the second dispensing device, and the unloading robot can operate simultaneously, thereby improving production efficiency. After the aforementioned loading robot, first dispensing device, second dispensing device, and unloading robot complete their operations, the first drive assembly 100 can drive the fixture 300 to translate along the first direction, thereby moving the fixture 300 to the next workstation. In the same conveying module 1000, when one fixture 300 needs to return to the loading position after unloading, it will interfere with the movement of the other fixture 300. At this time, the fixture 300 connected to the second drive assembly 200 can rise under the drive of the second drive assembly 200, thereby causing the two fixtures 300 to be staggered in the height direction to ensure that both fixtures 300 can move normally along the first direction. Subsequently, the fixture 300 can descend and reset, ensuring that it can normally load, dispense glue, and unload.

[0027] In summary, the first drive assembly 100 can drive the fixture 300 to sequentially pass through the loading position, the first dispensing position, the second dispensing position, and the unloading position to load, dispense glue, and unload the part 600. Multiple fixtures 300 are provided in the same conveying module 1000, which improves conveying efficiency. Under the drive of the second drive assembly 200, the fixture 300 can rise and fall to avoid other fixtures 300 in the same conveying module 1000 when it travels between the loading and unloading positions, ensuring normal conveying of the fixture 300. Furthermore, the multiple first drive assemblies 100 in the same conveying module 1000 are distributed along the height direction to better utilize vertical space and reduce space occupation. Additionally, the two conveying modules 1000 are distributed along the second direction, allowing for a more compact layout and further reducing space occupation.

[0028] Of course, it is also understood that in some other embodiments, the number of conveying modules 1000 may be three or more, and the number of fixtures 300 within the same conveying module 1000 may also be three or more.

[0029] Specifically, part 600 is, for example, the magnetic core of an inductor.

[0030] Specifically, the first drive assembly 100 is a lead screw assembly that extends along a first direction to the side of the loading robot, the first dispensing device, the second dispensing device, and the unloading robot.

[0031] Specifically, both the first and second directions are horizontal and perpendicular to each other.

[0032] Specifically, the second drive component 200 is a cylinder. It should be noted that in the prior art, to achieve the lifting and lowering of the fixture, a guide plate is provided, with a guide groove extending along a preset path of the fixture. One end of the fixture is engaged in the guide groove, and when the fixture moves, it can tilt upwards or downwards along the guide groove to avoid another fixture. Therefore, if the above configuration is used, a guide plate is required, resulting in space occupation. Furthermore, to ensure the stability of the fixture's lifting and lowering, the guide groove cannot be made too inclined. Consequently, the horizontal travel distance of the fixture is relatively long, thus increasing the space occupied by the device. In this application, the second drive component 200 is a cylinder. The first drive component 100 drives the cylinder to move horizontally, and the cylinder drives the fixture 300 to rise and fall. By using the cylinder to drive the fixture 300 to rise and fall, the second drive component 200 enables the fixture 300 to rise and fall rapidly in a short time, which reduces the horizontal travel of the fixture 300. This allows the loading position, the first glue application position, the second glue application position, and the unloading position to be arranged compactly in the horizontal direction, making the arrangement of the loading robot, the first glue application device, the second glue application device, and the unloading robot compact, reducing the space occupied, and eliminating the need to add the guide plate in the prior art, further reducing the space occupied.

[0033] Reference Figure 2 and Figure 4 According to some embodiments of this application, the conveying module 1000 further includes a limiting component 400, which includes a limiting block 410 and an elastic element 420. The fixture 300 has a limiting groove 310. One side of the limiting block 410 is connected to the fixture 300 through the elastic element 420, and the other side is used to abut against the part 600 located in the limiting groove 310.

[0034] Understandably, when part 600 is placed in the limiting groove 310, the limiting block 410, under the elastic force of the elastic element 420, tends to move closer to part 600 within the limiting groove 310. The limiting block 410, in conjunction with the groove wall of the limiting groove 310, clamps part 600. It should be noted that part 600 is a magnetic core, which is relatively brittle. By using the elastic element 420 to drive the limiting block 410 to abut against part 600 to limit part 600, damage to part 600 can be avoided.

[0035] Reference Figure 4 According to some embodiments of this application, at least two limit blocks 410 and elastic members 420 are provided and correspond one-to-one. At least two limit blocks 410 are used to intersect with the plane where the contact surface 411 of the part 600 is located.

[0036] It is understandable that the planes where the contact surfaces 411 of the multiple limiting members abut against the part 600 intersect, that is, the contact surfaces 411 of the multiple limiting members abut against the multiple intersecting sides of the part 600, pushing the part 600 to abut against the groove wall of the limiting groove 310, thereby limiting the part 600 in multiple directions and improving the limiting effect on the part 600.

[0037] Reference Figure 4 and Figure 5 According to some embodiments of this application, each fixture 300 is provided with a plurality of limiting grooves 310, and each limiting groove 310 corresponds to at least two limiting blocks 410; the limiting component 400 also includes a push rod 430, which can move relative to the fixture 300 to drive the limiting blocks 410 closer to or away from the product in the limiting groove 310.

[0038] Understandably, multiple limiting slots 310 are provided on the same fixture 300 to accommodate multiple parts 600 simultaneously, improving transmission efficiency. Furthermore, each limiting slot 310 corresponds to two limiting blocks 410, enhancing the limiting effect on the parts 600. Push rods 430 are connected to each limiting block 410. When push rods 430 move relative to the fixture 300, they can simultaneously move multiple limiting blocks 410 closer to or further away from the parts 600 within the limiting slots 310, thus cooperating with the limiting slots 310 to limit or release the limiting of the parts 600. Therefore, multiple limiting blocks 410 on the same fixture 300 are controlled by a single push rod 430, facilitating the simultaneous limiting or releasing of multiple parts 600.

[0039] Reference Figure 4 and Figure 5 According to some embodiments of this application, a plurality of limiting blocks 410 include a first limiting block 410a and a second limiting block 410b, and a plurality of elastic members 420 include a first elastic member 420a and a second elastic member 420b. The first limiting block 410a is used to abut against one side of the part 600 in a first direction, and the second limiting block 410b is used to abut against one side of the part 600 in a second direction. The first direction and the second direction intersect. The push rod 430 is movable relative to the fixture 300 along the first direction. The push rod 430 is provided with a first connecting portion 431 and a second connecting portion 432 connected together. The connecting part 431 is located on one side of the limiting groove 310 in the first direction. The first limiting block 410a is connected to the side of the first connecting part 431 near the limiting groove 310 through the elastic member 420. The second limiting block 410b is connected to the side wall of the fixture 300 located in the second direction of the limiting groove 310 through the second elastic member 420b. The second connecting part 432 has a first inclined surface 4322, and the second limiting block 410b has a second inclined surface 411b. The first inclined surface 4322 and the second inclined surface 411b slide to push the second limiting block 410b closer to or away from the limiting groove 310.

[0040] Understandably, when the push rod 430 moves forward in the first direction, the first connecting part 431, through the first elastic element 420a, drives the first limiting block 410a away from the limiting groove 310 in the first direction, thereby releasing the limitation on the part 600 in the first direction. At the same time, the first inclined surface 4322 of the second connecting part 432 slides and engages with the second inclined surface 411b of the second limiting block 410b, thereby pushing the second limiting block 410b away from the limiting groove 310 in the second direction, thereby releasing the limitation on the part 600 in the second direction. Simultaneously, the second limiting block 410b compresses the second elastic element 420b.

[0041] It is also understandable that when the push rod 430 moves in the opposite direction in the first direction, the first connecting part 431 drives the first limiting block 410a to approach the limiting groove 310 in the first direction through the first elastic member 420a, and abuts against the side of the part 600 in the first direction, so as to cooperate with the groove wall of the limiting groove 310 to limit the part 600 in the first direction. The first elastic member 420a can be compressed to buffer the contact between the first limiting block 410a and the part 600. Meanwhile, under the elastic force of the second elastic member 420b, the second inclined surface 411b of the second limiting block 410b remains in contact with the first inclined surface 4322 of the second connecting part 432. The first inclined surface 4322 and the second inclined surface 411b slide relative to each other. The second elastic member 420b pushes the second limiting block 410b closer to the limiting groove 310 and abuts against the side surface of the part 600 in the second direction, so as to cooperate with the groove wall of the limiting groove 310 to limit the part 600 in the second direction. The second elastic member 420b can be compressed to buffer the contact between the second limiting block 410b and the part 600.

[0042] Reference Figure 2 and Figure 5 According to some embodiments of this application, the limiting component 400 further includes a return spring 440, which is connected to the push rod 430 and the fixture 300, and is used to drive the push rod 430 to move the limiting block 410 closer to the limiting groove 310; the conveying module 1000 further includes an opening component, which is used to drive the push rod 430 to move so that the push rod 430 overcomes the elastic force of the return spring 440. Multiple opening components are provided, at least one opening component is provided corresponding to the loading position, and at least one opening component is provided corresponding to the unloading position.

[0043] Understandably, the return spring 440 has a force that pushes the push rod 430 to move in the opposite direction in the first direction. Without the opening component, the push rod 430 moves in the opposite direction in the first direction under the action of the return spring 440, so as to drive the first limiting block 410a and the second limiting block 410b to clamp the part 600 in the limiting groove 310. When the fixture 300 moves to the loading or unloading position, the opening component can push the push rod 430 to move in the second direction in the forward direction to overcome the force of the return spring 440. The push rod 430 drives the first limiting block 410a and the second limiting block 410b away from the limiting groove 310, releasing the limiting of the part 600.

[0044] Reference Figure 2 According to some embodiments of this application, one end of the push rod 430 extends through the edge of the fixture 300 to form a first mating part 433, and the opening component includes a driver 450, the driving end of the driver 450 moves along a first direction and is used to push the first mating part 433.

[0045] It is understood that the drive end of the driver 450 moves along the first direction, thereby pushing the first mating part 433 to move along the first direction, so as to drive the push rod 430 to move along the first direction, thereby causing the first limit block 410a and the second limit block 410b to release the limit on the part 600, so as to facilitate the picking and putting of materials.

[0046] Specifically, the driver 450 is located on the side of the loading position. After the fixture 300 moves to the loading position, the driver 450 is located on one side of the fixture 300 in the first direction. The driving end of the driver 450 moves forward in the first direction and pushes the push rod 430 to move forward in the first direction through the first mating part 433.

[0047] Specifically, the driver 450 is a cylinder.

[0048] Reference Figure 2 According to some embodiments of this application, the limiting component 400 further includes a second mating part 434, which is connected to the push rod 430. A roller 4341 is provided on the second mating part 434. The opening component includes a inserter that can move along the height direction. The inserter is used to engage with the roller 4341 to push the second mating part 434 to move along the first direction.

[0049] It is understandable that the inserter is provided with a third inclined surface, which can slide and engage with the roller 4341 during the descent of the inserter. The roller 4341 drives the second mating part 434 to move along the first direction, thereby driving the push rod 430 to move along the first direction, thereby driving the first limit block 410a and the second limit block 410b to release the restriction on the part 600, so as to facilitate the picking and putting of materials.

[0050] Specifically, the insert is located above the unloading position. After the fixture 300 moves to the unloading position, the insert is located above the roller 4341. The insert descends and slides with the roller 4341, and pushes the push rod 430 to move forward in the first direction through the second mating part 434.

[0051] Reference Figure 2 According to some embodiments of this application, the conveying module 1000 further includes an air blowing assembly 500, which is set to the loading position and is used to blow air toward the fixture 300 located at the loading position.

[0052] Understandably, part 600 is a magnetic core, which is easily scratched. When the unloaded jig 300 moves from the unloading position to the loading position, there is a risk that debris may fall into the limiting groove 310 and scratch part 600 when it is subsequently limited. Therefore, an air blowing component 500 is set at the loading position. Before loading the jig 300, the air blowing component 500 will blow air toward the limiting groove 310 of the jig 300 to blow the debris out of the limiting groove 310 and reduce the risk of scratching the magnetic core.

[0053] The dispensing machine according to a second aspect of this application includes the conveying device of the first aspect embodiment.

[0054] The conveying device according to the second aspect embodiment of this application has all the beneficial effects of the conveying device according to the first aspect embodiment, which will not be repeated here.

[0055] As described above, the dispensing machine in the second aspect embodiment further includes a loading robot, a first dispensing device, a second dispensing device, and a unloading robot. The first driving assembly 100 is used to drive the fixture 300 to move horizontally in a first direction. A loading position, a first dispensing position, a second dispensing position, and an unloading position are formed along the moving path of the fixture 300. The loading robot is located beside the loading position, the first dispensing device is located beside the first dispensing position, the second dispensing device is located beside the second dispensing position, and the unloading robot is located beside the unloading position. The loading robot loads the empty fixture 300 at the loading position. The first dispensing device dispenses glue to the part 600 in the fixture 300 at the first dispensing position. The second dispensing device dispenses glue to the part 600 in the fixture 300 at the second dispensing position. The unloading robot unloads the part 600 in the fixture 300 at the unloading position after glue dispensing. The glue dispensed by the first dispensing device and the second dispensing device are different, and the glue dispensing positions on the part 600 are different.

[0056] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
