Abstract
Description
Technical Field
[0001] This application relates to the field of material handling technology, and in particular to material handling mechanisms and sorting machines. Background Technology
[0002] Under normal temperature conditions, the accuracy of the chip-picking nozzle of the sorting machine can be guaranteed. However, under high and low temperature conditions, the crossbeam supporting the nozzle on the robotic arm undergoes significant thermal deformation along its length. Its ends are constrained by other structures and cannot expand freely, causing the crossbeam to bend and deform. Prolonged alternating hot and cold temperatures can lead to material failure in the crossbeam due to unreleased thermal stress, and simultaneously affect the accuracy of the nozzle's pick-up / placement position, resulting in the robotic arm missing chips. Utility Model Content
[0003] Therefore, it is necessary to provide a material conveying mechanism and sorting machine to address the problem that the material conveying mechanism fails due to alternating hot and cold ambient temperatures, which reduces the accuracy of the nozzle's pick-up / discharge position and leads to chip leakage.
[0004] In a first aspect, this application provides a material conveying mechanism, comprising:
[0005] Install components;
[0006] A crossbeam extends longitudinally along a first direction and has a first end and a second end disposed opposite to each other in the first direction.
[0007] An adsorption component is movably disposed on the crossbeam along the first direction;
[0008] A stress relief assembly, wherein the first end is connected to the mounting assembly via the stress relief assembly, the stress relief assembly allowing the first end to move relative to the mounting assembly in the first direction; and
[0009] A position adjustment component is connected between the second end and the mounting component and is configured to change the relative position of the second end and the mounting component in the first direction.
[0010] In some embodiments, the stress relief assembly includes a slide rail and a slider, one of which is disposed on the mounting assembly and the other is disposed on the first end;
[0011] The slide rail extends along the first direction, and the slider is disposed on the slide rail, and the two can slide relative to each other in the first direction.
[0012] In some embodiments, the mounting component forms a mounting channel, the mounting channel is disposed through the first direction, and the first end passes through the mounting channel;
[0013] The slide rail and the slider are provided between the opposite sides of the first end and the inner wall of the mounting channel.
[0014] In some embodiments, the position adjustment assembly includes a first connector, a second connector, and a power mechanism. The first connector is fixed to the mounting assembly, the second connector is fixed to the second end, and the power mechanism connects the first connector and the second connector and is configured to change the relative position between the first connector and the second connector along the first direction.
[0015] In some embodiments, the power mechanism includes a motor, a coupling, and a lead screw. The second connecting member is provided with a threaded hole that mates with the lead screw. One end of the lead screw passes through the threaded hole and is fixedly connected to the first connecting member. The other end of the lead screw is connected to the output shaft of the motor via the coupling.
[0016] In some embodiments, the position adjustment assembly further includes a guide post, and the second connector is provided with a guide hole;
[0017] One end of the guide post is fixed to the first connector, and the other end is located inside the guide hole, and can move relative to the guide hole in the first direction.
[0018] In some embodiments, the material conveying mechanism includes a distance sensor disposed on the crossbeam; the distance sensor is disposed opposite to the first connecting member in the first direction and is used to measure the distance between itself and the first connecting member;
[0019] The power mechanism is connected to the distance sensor signal to change the interval between the first connector and the second connector according to the measurement value of the distance sensor.
[0020] In some embodiments, the mounting assembly includes a first guide portion and a second guide portion, the first guide portion being connected to the first end via the stress relief assembly, and the second guide portion being connected to the second end via the position adjustment assembly;
[0021] Both the first guide portion and the second guide portion are configured to guide the movement of the crossbeam along a second direction, which is perpendicular to the first direction.
[0022] In some embodiments, the adsorption assembly includes a suction nozzle and a base, the base being movably disposed on the crossbeam along the first direction;
[0023] The suction nozzle is movably disposed on the base along a third direction.

[0025] The aforementioned material conveying mechanism and sorting machine utilize a stress-relieving component at the first end of the crossbeam to adapt to changes in the crossbeam's lateral span caused by thermal expansion and contraction.

Furthermore, the material conveying mechanism adjusts the distance between the second end and the mounting component via a position adjustment component, ensuring a consistent relative position between the adsorption component and the mounting component on the crossbeam. This guarantees the positioning accuracy of the adsorption component in the first direction, improves the accuracy of chip suction / discharge, and reduces the probability of chip leakage.

[0039] In response to the problems mentioned in the background art, this application provides a material conveying mechanism that can release stress concentration caused by alternating hot and cold ambient temperatures, prevent material failure, improve the accuracy of the nozzle's pick-up / placement position, and reduce the probability of missing chips.
[0040] The material handling mechanism described in this application can be applied to, but is not limited to, the transport of chips. This application uses chips as an example to illustrate the application of the material handling mechanism, and does not limit its application scenarios.
[0041] Figure 1 This is a schematic diagram of the external shape of the material conveying mechanism 100 in some embodiments. Figure 2 for Figure 1 Another view of the material handling mechanism 100 shown. Figure 3 for Figure 1 An enlarged view of point A in the material handling mechanism 100 shown. Figure 4 for Figure 2 Enlarged view of point B in the middle.
[0042] Reference Figure 1 and Figure 3The material handling mechanism 100 in this embodiment includes a mounting assembly 10, a crossbeam 20, an adsorption assembly 30, a stress relief assembly 40, and a position adjustment assembly 50. The crossbeam 20 extends longitudinally along a first direction X and has a first end 20a and a second end 20b disposed opposite to each other in the first direction X. The adsorption assembly 30 is movably disposed on the crossbeam 20 along the first direction X. The first end 20a is connected to the mounting assembly 10 via the stress relief assembly 40, which allows the first end 20a to move relative to the mounting assembly 10 in the first direction X. The position adjustment assembly 50 is connected between the second end 20b and the mounting assembly 10 and is configured to change the relative position of the second end 20b and the mounting assembly 10 in the first direction X.
[0043] Mounting assembly 10 is used to mount the material conveying mechanism 100 onto an external load-bearing object. Specifically, the load-bearing object can be a movable mechanism or a fixed mechanism. If the load-bearing object is a movable mechanism (such as a transport vehicle), the mounting assembly 10 can be fixedly mounted on the load-bearing object. If the load-bearing object is a fixed mechanism (such as a track), the mounting assembly 10 can be movably mounted on the load-bearing object. In this way, the material conveying mechanism 100 can move and transport materials.
[0044] The crossbeam 20 is a beam structure arranged along the longitudinal direction X. In practical applications, the first direction X corresponds to the horizontal direction. The adsorption component 30 is movably arranged on the crossbeam 20 along its length. It typically uses negative pressure adsorption to directly pick up the chip, achieving damage-free chip transfer and facilitating chip removal / placement.
[0045] The adsorption assembly 30 can be constructed using conventional methods. As an example, the adsorption assembly 30 includes a base 32, a suction nozzle 31, and a transverse motor 53a, with multiple suction nozzles 31 disposed on the base 32. The base 32 includes multiple wheels, and the transverse motor 53a drives each wheel to roll synchronously along the crossbeam 20, so that the base 32 drives the suction nozzles 31 to move along the crossbeam 20 in the first direction X.
[0046] The stress relief assembly 40 is connected between the first end 20a of the crossbeam 20 and the mounting assembly 10. It allows the first end 20a to move in the first direction X to release the thermal expansion deformation of the crossbeam 20, preventing material failure caused by long-term thermal expansion and contraction cycles. Furthermore, it can adapt to changes in the lateral span of the crossbeam 20 due to thermal expansion and contraction, ensuring the straightness of the crossbeam 20. The stress relief assembly 40 can be constructed in various ways. For example, the stress relief assembly 40 is a spring assembly that is elastically deformable in the first direction X, and the spring assembly is connected between the first end 20a and the mounting assembly 10 along the first direction X.
[0047] Understandably, when the crossbeam 20 changes its lateral span, the position of the adsorption component 30 mounted on the crossbeam 20 in the first direction X will also change. At this time, the mounting component 10 is used as a positioning reference to determine the position of the adsorption component 30 in the first direction X, ensuring its positioning accuracy in the first direction X. Specifically, the position adjustment component 50 is used to change the relative position between the second end 20b of the crossbeam 20 and the mounting component 10, adjusting the relative position of the adsorption component 30 and the mounting component 10 so that the relative position of the adsorption component 30 and the mounting component 10 remains constant, ensuring the positioning accuracy of the adsorption component 30 in the first direction X. For example, the position adjustment component 50 includes a telescopic cylinder, one end of which is connected to the mounting component 10, and the other end is connected to the second end 20b.
[0048] In this embodiment, the material conveying mechanism 100, through the stress relief component 40 at the first end 20a of the crossbeam 20, adapts to changes in the lateral span of the crossbeam 20 caused by thermal expansion and contraction, preventing the crossbeam 20 from bending, maintaining its straightness, and effectively releasing thermal stress on the crossbeam 20, thus preventing material failure of the crossbeam 20 due to long-term thermal expansion and contraction cycle thermal fatigue. Furthermore, the material conveying mechanism 100, through the position adjustment component 50, changes the distance between the second end 20b and the mounting component 10, ensuring that the relative position of the adsorption component 30 disposed on the crossbeam 20 and the mounting component 10 remains constant. This guarantees the positioning accuracy of the adsorption component 30 in the first direction X, improves its chip adsorption / release accuracy, and reduces the probability of the adsorption component 30 missing chips.
[0049] Understandably, when the position adjustment component 50 changes the position of the second end 20b of the crossbeam 20 relative to the mounting component 10, the stress relief component 40 does not obstruct the position change of the crossbeam 20 in the first direction X.
[0050] In some embodiments, refer to Figure 3 The stress relief assembly 40 includes a slide rail 41 and a slider 42, one of which is disposed on the mounting assembly 10 and the other is disposed on the first end 20a. The slide rail 41 extends along a first direction X, and the slider 42 is disposed on the slide rail 41, and the two can slide relative to each other in the first direction X.
[0051] When the crossbeam 20 expands its lateral span due to thermal expansion, it pushes the slider 42 to move along the slide rail 41 in a direction away from the second end 20b. This can adapt to the change in the lateral span of the crossbeam 20, prevent the crossbeam 20 from bending, maintain its straightness, and effectively release the thermal stress on the crossbeam 20, avoiding material failure of the crossbeam 20 due to long-term thermal expansion and contraction cycle thermal fatigue.
[0052] At this point, the stress relief assembly 40 is formed by combining the slide rail 41 and the slider 42. The structure is simple and easy to implement.
[0053] Understandably, of the matching slider 42 and slide rail 41, one is located on the mounting assembly 10 and the other is located on the first end 20a. It is not excluded that both the mounting assembly 10 and the first end 20a may have slide rail 41 and slider 42, as long as the slide rail 41 on both can be installed in conjunction with the slider 42 on the other.
[0054] In some embodiments, refer to Figure 3 The mounting component 10 has a mounting channel 10a, which extends along a first direction X, and a first end 20a passes through the mounting channel 10a. A slide rail 41 and a slider 42 are provided between the opposite sides of the first end 20a and the inner wall of the mounting channel 10a.
[0055] On the one hand, the installation channel 10a is arranged through the first direction X, so there is no need to consider the size of the deformation space it can provide for the crossbeam 20, which simplifies the structural design. On the other hand, the installation channel 10a can limit the position of the first end 20a in the second direction Y, which is perpendicular to the first direction X, to ensure that the crossbeam 20 does not change position relative to the installation assembly 10 in the second direction Y, which helps to improve the positional accuracy of the adsorption assembly 30.
[0056] Moreover, the first end 20a is connected to the mounting assembly 10 on both opposite sides in the second direction Y through the cooperation of the slide rail 41 and the slider 42, so that the force on both sides is uniform and the movement is more stable.
[0057] In some embodiments, refer to Figure 4 The position adjustment assembly 50 includes a first connector 51, a second connector 52, and a power mechanism 53. The first connector 51 is fixed to the mounting assembly 10, the second connector 52 is fixed to the second end 20b, and the power mechanism 53 is connected to the first connector 51 and the second connector 52 and is configured to change the relative position between the first connector 51 and the second connector 52 along the first direction X.
[0058] The first connector 51 and the second connector 52 can be fixedly connected to the mounting assembly 10 and the second end 20b respectively by means of fastening, snap-fitting, welding, etc. Specifically, the power mechanism 53 can be a telescopic cylinder, a linear module, etc. Understandably, the relative position between the first connector 51 and the second connector 52 changes synchronously with the relative position between the adsorption assembly 30 and the mounting assembly 10.
[0059] At this time, the position adjustment component 50 changes the relative position of the first connector 51 and the second connector 52 in the first direction X through the power mechanism 53. When the transverse span of the crossbeam 20 changes and the position of the adsorption component 30 in the first direction X changes, the relative position of the second end 20b and the mounting component 10 in the first direction X can be changed, thereby keeping the relative position of the adsorption component 30 and the mounting component 10 constant and ensuring the positioning accuracy of the adsorption component 30 in the first direction X.
[0060] Specifically, in the embodiments, combined with Figure 4 Understandably, the power mechanism 53 includes a motor 53a, a coupling 53b, and a lead screw 53c. The second connecting member 52 is provided with a threaded hole that mates with the lead screw 53c. One end of the lead screw 53c passes through the threaded hole and is connected to the first connecting member 51. The other end of the lead screw 53c is connected to the output shaft of the motor 53a via the coupling 53b.
[0061] Coupling 53b is a conventional device that connects two shafts or a shaft and a rotating component, allowing them to rotate together without disengaging during the transmission of motion and power. One end of the lead screw 53c is fixed to the output shaft of the motor 53a via coupling 53b, while its other end is rotatably connected to the first connecting member 51. The first connecting member 51 allows the lead screw 53c to rotate, and the relative position between the first connecting member 51 and the output shaft of the motor 53a remains unchanged while the lead screw 53c is constrained.
[0062] The lead screw 53c passes through the threaded hole on the second connector 52. The threaded hole serves as a threaded pair that mates with the lead screw 53c. When the output shaft of the motor 53a drives the lead screw 53c to rotate, the lead screw 53c converts its rotational motion into linear motion that drives the second connector 52 to move in the first direction X. The movement of the second connector 52 drives the adsorption assembly 30 to move, thereby keeping the relative position of the adsorption assembly 30 and the mounting assembly 10 constant, ensuring the positioning accuracy of the adsorption assembly 30 in the first direction X.
[0063] At this time, the position of the second connector 52 and the first connector 51 in the first direction X is changed through the cooperation of the motor 53a, the lead screw 53c and the threaded hole. The structure is simple and easy to implement.
[0064] Optionally, a fixed seat 53d is provided on the crossbeam 20, and the motor 53a is mounted on the fixed seat 53d. Since the first connecting member 51 is fixed relative to the mounting assembly 10, the crossbeam 20 is movable relative to the first connecting member 51. Under the constraint of the lead screw 53c, the position of the motor 53a remains stationary. At this time, the motor 53a can be slidably mounted on the crossbeam 20 through the fixed seat 53d, so that when the crossbeam 20 is displaced relative to the mounting assembly 10 in the first direction X, the relative position between the fixed seat 53d and the crossbeam 20 is allowed to change.
[0065] In some embodiments, refer to Figure 4 The position adjustment assembly 50 also includes a guide post 54. The second connector 52 is provided with a guide hole (not shown). One end of the guide post 54 is fixed to the first connector 51, and the other end is located in the guide hole and can move relative to the guide hole in the first direction X.
[0066] Specifically, a sliding bushing can be installed inside the guide hole, and the guide post 54 is fitted inside the sliding bushing and can slide relative to the sliding bushing in the first direction X. At this time, the cooperation between the guide hole and the guide post 54 can restrict the movement of the second end 20b in the first direction X, which not only helps to improve the smoothness of the movement of the second connecting member 52, but also helps to maintain the straightness of the crossbeam 20 in the first direction X and avoid its bending deformation.
[0067] In some embodiments, refer to Figure 4 The material handling mechanism 100 also includes a distance sensor 60, which is disposed on the crossbeam 20. The distance sensor 60 is positioned opposite the first connecting member 51 in the first direction X, and is used to measure the distance between itself and the first connecting member 51. The power mechanism 53 is signal-connected to the distance sensor 60, and is used to change the interval distance between the first connecting member 51 and the second connecting member 52 according to the measurement value of the distance sensor 60.
[0068] The distance sensor 60 is fixed relative to the crossbeam 20 and can move with the second end 20b of the crossbeam 20. The power mechanism 53 may include a controller, which is communicatively connected to the distance sensor 60 and controllably connected to the motor 53a. The controller can control the start and stop of the motor 53a based on the test value of the distance sensor 60.
[0069] Specifically, when the lateral span of the beam 20 changes, the distance between the distance sensor 60 and the first connecting member 51 changes accordingly. The motor 53a is controlled to operate by comparing the deviation of this distance from a preset value, so that the distance between the distance sensor 60 and the first connecting member 51 is close to or equal to the preset value. During this process, the adsorption assembly 30 and the distance sensor 60 remain in fixed positions, and the change in the position of the distance sensor 60 is equal to the change in the position of the adsorption assembly 30. When the distance between the distance sensor 60 and the first connecting member 51 reaches the preset value, the relative position of the adsorption assembly 30 and the mounting assembly 10 returns to its original state.
[0070] At this time, the position change of the adsorption component 30 can be accurately determined by the ranging sensor, so as to realize the accurate restoration of the position of the adsorption component 30 and greatly improve its positioning accuracy.
[0071] The ranging sensor can be a laser sensor, an infrared sensor, etc., and there are no specific limitations.
[0072] In some embodiments, refer to Figure 1 and Figure 2 The mounting assembly 10 includes a first guide portion 11 and a second guide portion 12. The first guide portion 11 is connected to the first end 20a via a stress relief assembly 40, and the second guide portion 12 is connected to the second end 20b via a position adjustment assembly 50. Both the first guide portion 11 and the second guide portion 12 are configured to guide the crossbeam 20 to move along a second direction Y, which is perpendicular to the first direction X.
[0073] If the first direction X is defined as the transverse direction, and the second direction Y is the longitudinal direction perpendicular to the transverse direction, both are horizontal in actual use. The mounting assembly 10 is movably mounted on an external load-bearing object along the second direction Y via the first guide portion 11 and the second guide portion 12. Specifically, the first guide portion 11 and the second guide portion 12 include a base and a guide rail. The guide rail is disposed on the base and can be movably engaged with the external load-bearing object in the second direction Y. The base of the first guide portion 11 is connected to the first end 20a of the crossbeam 20 via a stress relief assembly 40. The base of the second guide portion 12 is connected to the second end 20b of the crossbeam 20 via a position adjustment assembly 50. Specifically, the first connector 51 of the position adjustment assembly 50 is fixed to the base of the second guide portion 12.
[0074] At this time, the crossbeam 20 is driven to move in the second direction Y by the first guide part 11 and the second guide part 12 on both sides, thereby realizing the position adjustment of the adsorption component 30 in the second direction Y. This not only expands the adsorption range of the adsorption component 30, but also ensures that the crossbeam 20 is subjected to uniform force on both sides, which enables the adsorption component 30 to move smoothly in the second direction Y.
[0075] In some embodiments, refer to Figure 1 and Figure 2 The adsorption assembly 30 includes a suction nozzle 31 and a base 32. The base 32 is movably disposed on the crossbeam 20 along a first direction X. The suction nozzle 31 is movably disposed on the base 32 along a third direction Z.
[0076] As mentioned above, the base 32 can be movably mounted on the crossbeam 20 via wheels. Alternatively, a linear module can be mounted on the crossbeam 20 to move the base 32. When the base 32 moves along the first direction X, it moves the suction nozzle 31 along the first direction X.
[0077] The suction nozzle 31 can move relative to the base 32 in a third direction Z, which corresponds to the vertical direction and is perpendicular to both the first direction X and the second direction Y mentioned above. Specifically, a lifting motor 53a can be installed on the base 32 to drive the suction nozzle 31 to rise and fall. When it is necessary to pick up a chip, the suction nozzle 31 first descends to a certain height to pick up the chip, and then rises to a certain height to transfer the chip.
[0078] Multiple suction nozzles 31 can be installed on the base 32, and each or multiple suction nozzles 31 can be independently lifted and lowered by a lifting motor 53a.
[0079] In one specific embodiment of this application, the material conveying mechanism 100 includes the aforementioned mounting assembly 10, crossbeam 20, adsorption assembly 30, stress relief assembly 40, and position adjustment assembly 50. The stress relief assembly 40 includes the aforementioned slide rail 41 and slider 42; the position adjustment assembly 50 includes the aforementioned first connector 51, second connector 52, motor 53a, and lead screw 53c; the mounting assembly 10 includes the aforementioned first guide portion 11 and second guide portion; and the adsorption assembly 30 includes the aforementioned base 32 and suction nozzle 31.
[0080] In practical applications, the base 32 moves along the crossbeam 20 in the first direction X, the first guide part 11 and the second guide part 12 move in the second direction Y, and the suction nozzle 31 itself moves in the third direction Z, so that the position of the suction nozzle 31 can be independently adjusted in three different directions, making the material conveying mechanism 100 adaptable to a variety of material conveying scenarios.
[0081] In addition, this application embodiment also provides a sorting machine, including the material conveying mechanism 100 in the above embodiment. The material conveying mechanism 100 is used for transferring chips between various processes of the sorting machine.
[0082] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
