Description

Technical Field

[0001] This utility model relates to the technical field of claw machine accessories, specifically to a moving mechanism for an overhead crane, the overhead crane, and the claw machine. Background Technology

[0002] Claw machines are a common entertainment device that is activated by inserting coins or scanning QR codes. Players control a crane to grab toys or prizes from inside the machine by operating a joystick or buttons. Therefore, the crane is a key component of the claw machine, and its structure and performance play a crucial role in the machine's overall performance.

[0003] Generally, the crane mechanism of a claw machine mainly consists of the following key components: a mainboard and controller; a moving mechanism; a claw lifting mechanism; and a claw (mechanical arm). The crane's moving mechanism typically includes a lateral moving unit and a longitudinal moving unit, used to control the claw's left-right and forward-backward movement within the claw machine, respectively. For example, the lateral moving unit drives the longitudinal moving unit to reciprocate in the lateral direction, the longitudinal moving unit drives the claw lifting mechanism to reciprocate in the longitudinal direction, and the claw lifting mechanism drives the claw to rise or fall.

[0004] However, the following problems often occur during the use of common moving mechanisms: When the longitudinal moving unit drives the gripper lifting mechanism to one end, it can easily lead to different movement speeds at the two ends of the longitudinal moving unit when the lateral moving unit drives the longitudinal moving unit. Generally, to detect whether the longitudinal moving unit has reached its limit position, a detection unit is set at the end of the longitudinal moving unit. The different movement speeds at the two ends of the longitudinal moving unit require detection units to be set at both ends of the longitudinal moving unit, which increases costs. Moreover, the different movement speeds at the two ends of the longitudinal moving unit can also easily cause the longitudinal moving unit to jam during the movement driven by the lateral moving unit. It can also easily lead to a decrease in the accuracy of the lateral moving unit driving the longitudinal moving unit. Utility Model Content

[0005] During the research and development process, the applicant repeatedly studied the above-mentioned problems and found that the main reason for the different movement speeds at both ends of the longitudinal moving unit when the lateral driving unit drives the longitudinal moving unit is that the lateral moving unit generally drives the longitudinal moving unit by driving one end of the longitudinal moving unit. This driving method often results in the end of the longitudinal moving unit connected to the lateral moving unit moving faster than the other end. To solve at least one of the above problems, according to one aspect of this utility model, a moving mechanism for an overhead crane is provided.

[0006] The moving mechanism for the overhead crane includes a first moving unit, which drives a second moving unit to move, and the second moving unit drives a gripper lifting mechanism to move. The first moving unit includes a first guiding mechanism for guiding the movement of the second moving unit and a first driving module for driving the movement of the second moving unit. Two sets of the first guiding mechanisms are provided, and the first driving module is located between the two sets of the first guiding mechanisms.

[0007] Because the first moving unit used to drive the second moving unit in this application is provided with a first driving module and two sets of first guiding mechanisms, the movement of the second moving unit is guided by the two sets of first guiding mechanisms to ensure the stability of the movement of the second moving unit. At the same time, by setting the first driving module between the two sets of first guiding mechanisms, the guidance provided by the two sets of first guiding mechanisms to the second moving unit under the drive of the first driving module is more synchronized, so as to reduce the problem of asynchronous movement of the second moving unit at different positions.

[0008] In some implementations, two sets of first guide mechanisms are respectively disposed at both ends of the second moving unit. This significantly reduces the problem of asynchronous movement of the second moving unit at different positions.

[0009] In some implementations, the first drive module is centrally positioned between the two sets of first guide mechanisms. This allows the two sets of first guide mechanisms to provide more synchronized guidance to the second moving unit under the drive of the first drive module. Especially when the two sets of first guide mechanisms are respectively positioned at both ends of the second moving unit, it ensures that the two sets of first guide mechanisms provide synchronized guidance to the second moving unit under the drive of the first drive module, avoiding the problem of different movement speeds at the two ends of the second moving unit under the drive of the first drive module.

[0010] In some embodiments, the first drive module includes a first drive device and a first transmission unit; wherein the first drive device is fixedly mounted relative to the frame and is used to drive the first transmission unit to move the second moving unit. This application achieves the first drive module driving the second moving unit by having the first drive device drive the first transmission unit to move. This allows for more flexible positioning of the first drive device. When the first drive device is mounted on a relatively stable frame, it can provide a more stable driving force to the second moving unit, enabling the entire moving mechanism to drive the gripper lifting mechanism more stably.

[0011] In some embodiments, the first guiding mechanism includes a first guide rail and a second guide rail fixedly disposed relative to the frame, and at least one first slider and at least one second slider disposed on the second moving unit; the first slider is provided with a first groove adapted to the first guide rail and the second guide rail, and the second slider is provided with a second groove adapted to the first guide rail and the second guide rail; the first slider is adapted to at least one of the first guide rail and the second guide rail; the second slider is adapted to at least one of the first guide rail and the second guide rail, the first guide rail is disposed on a first side of the first slider and the second slider, and the second guide rail is disposed on the side of the first slider and the second slider opposite to the first guide rail.

[0012] Because existing technologies typically use an "I"-shaped guide rail with an "I"-shaped groove in the slider, a clearance is usually required to achieve this fit. This can easily lead to swaying when the second moving unit is guided by the common guide rail and slider structure, especially when the drive module is positioned on one side of the guide mechanism rather than centrally between two guide mechanisms. In this case, the second moving unit is prone to swaying. However, the first guide mechanism of this application, by placing at least two sliders between two guide rails, allows adjustment of the sliders' mounting positions so that their opposing sides abut against the two guide rails, preventing swaying of the second moving unit during movement under the guidance of the first guide mechanism.

[0013] In some embodiments, the first driving device is a first motor, which is fixedly mounted relative to the frame; the first transmission unit includes a first driving pulley, a first driven pulley, and a first belt, the first driven pulley is pivotally mounted on the frame, and the first belt is sleeved and adapted to the outer periphery of the first driving pulley and the first driven pulley; the first motor drives the first driving pulley to rotate the first belt while simultaneously driving the first driven pulley to rotate; the first belt between the first driving pulley and the first driven pulley is arranged in a direction parallel to the first guide rail, and the second moving unit is mounted on the first belt.

[0014] Therefore, when the first motor is driven, the second moving unit can be driven to reciprocate along the extension direction of the first guide rail and the second guide rail via the first belt; moreover, the first transmission unit adopts a pulley belt transmission structure, which can reduce costs.

[0015] In some embodiments, at least one of the first groove and the second groove is an annular groove, and the cross-section of at least one of the first groove and the second groove is arc-shaped. At least one of the first slider and the second slider is rotatably disposed relative to the second moving unit about the central axis of the annular groove, and the arrangement direction of the first slider and the second slider is not parallel to the extension direction of the first lead screw. This application, through the arrangement of the position and shape of the first slider and the second slider, ensures that the opposite sides of the first slider and the second slider abut against the first guide rail and the second guide rail respectively, preventing the second moving unit from wobbling during movement under the guidance of the first guide mechanism; and also ensures that the first slider and the second slider move smoothly along the extension direction of the first guide rail and the second guide rail.

[0016] In some embodiments, the moving mechanism for the overhead crane further includes a second moving unit; the first moving unit drives the second moving unit to reciprocate along a first direction; the second moving unit drives the gripper lifting mechanism to reciprocate along a second direction; the first direction and the second direction are not parallel. Thus, driven by the first and second moving units, the gripper lifting structure can move within the plane formed by the first and second directions.

[0017] In some embodiments, the second moving unit includes a second guide mechanism for guiding the movement of the gripper lifting mechanism, and a second drive module for driving the movement of the gripper lifting mechanism. Both the second drive module and the second guide mechanism are fixedly disposed relative to the first drive module and the first guide mechanism, respectively, with both ends of the second guide mechanism fixedly disposed relative to two sets of first guide mechanisms. Because both ends of the second guide mechanism are fixedly disposed relative to two sets of first guide mechanisms, the smooth movement of the second guide mechanism can be ensured by the two sets of first guide mechanisms, avoiding swaying during the movement of the second guide mechanism and thus preventing asynchronous movement at different positions of the second moving unit.

[0018] In some embodiments, the moving mechanism for the overhead crane further includes a mounting bracket; the second drive module is mounted on the first transmission unit of the first drive module via the mounting bracket; the second guide mechanism is mounted on the first guide mechanism via the mounting bracket, and both ends of the mounting bracket are respectively mounted on at least one of the first slider and the second slider of the two sets of first guide mechanisms. This ensures that the second drive module and the second guide mechanism can move smoothly under the drive of the first moving unit, avoiding the problem of asynchronous movement at different positions of the second moving unit.

[0019] In some embodiments, two sets of second guide mechanisms are provided, and the second drive module is disposed between the two sets of second guide mechanisms. Since the second moving unit for driving the gripper lifting mechanism of this application includes a second drive module and two sets of second guide mechanisms, the two sets of second guide mechanisms provide guidance for the movement of the gripper lifting mechanism, ensuring the stability of its movement. Simultaneously, by placing the second drive module between the two sets of second guide mechanisms, the guidance provided by the two sets of second guide mechanisms to the gripper lifting mechanism is more synchronized under the drive of the second drive module, reducing the problem of asynchronous movement at different positions of the gripper lifting mechanism.

[0020] In some embodiments, the second drive module includes a second drive device and a second transmission unit; the second drive device is a second motor, which is fixedly mounted relative to the mounting bracket; the second transmission unit includes a second driving pulley, a second driven pulley, and a second belt, the second driven pulley being pivotally mounted on the mounting bracket, and the second belt being sleeved on the outer periphery of the second driving pulley and the second driven pulley; the second motor drives the second driving pulley to rotate the second belt while simultaneously rotating the second driven pulley; the gripper lifting mechanism is mounted on the second belt and the second guide mechanism. Thus, when driven by the second motor, the gripper lifting mechanism can be driven to reciprocate in a second direction via the second belt; moreover, the second transmission unit adopts a pulley and belt drive structure, which can reduce costs.

[0021] In some embodiments, the second guiding mechanism includes a mutually compatible third guide rod and a third slider. The third slider is sleeved on the third guide rod, which is fixedly disposed relative to the mounting bracket and extends along a second direction. The gripper lifting mechanism is fixedly disposed relative to the third slider. Because the third guiding mechanism uses a mutually compatible third guide rod and a third slider, and the third slider is sleeved on the third guide rod, and both sets of third sliders are disposed on the gripper lifting mechanism, swaying can be avoided when the third slider moves along the extension direction of the third guide rod, ensuring the stability of the movement of the gripper lifting mechanism driven by the second guiding mechanism.

[0022] According to another aspect of this application, an overhead crane is provided. The overhead crane includes a gripper lifting mechanism; and the aforementioned moving mechanism for the overhead crane; wherein the gripper lifting mechanism is disposed on a second moving unit and is capable of reciprocating along a second direction under the drive of the second moving unit.

[0023] Because the first moving unit of the moving mechanism of this application is provided with a first driving module and two sets of first guiding mechanisms, the movement of the second moving unit is guided by the two sets of first guiding mechanisms to ensure the stability of the movement of the gripper lifting mechanism driven by the second moving unit. At the same time, by setting the first driving module between the two sets of first guiding mechanisms, the guidance provided by the two sets of first guiding mechanisms to the second moving unit under the drive of the first driving module is more synchronized, so as to reduce the problem of asynchronous movement of the second moving unit at different positions.

[0024] According to another aspect of this application, a claw machine is provided. The claw machine includes a frame and the aforementioned moving mechanism for a crane; wherein at least one of the first drive module and the first guide mechanism of the moving mechanism for the crane is fixed relative to the frame; or, it includes a frame and the aforementioned crane; wherein the moving mechanism for the crane is fixed relative to the frame. Because at least one of the first drive module and the first guide mechanism is fixed relative to the frame, or the moving mechanism for the crane is fixed relative to the frame, the stability of the movement of the claw lifting mechanism driven by the moving mechanism can be ensured.

[0046] Figures 1 to 14 The diagram schematically shows a moving mechanism 20 for an overhead crane according to one embodiment of the present invention.

[0047] like Figure 3 As shown, the moving mechanism 20 for the overhead crane includes a first moving unit 21. (As indicated...) Figure 1 and Figure 6 As shown, the first moving unit 21 drives the second moving unit 22 to reciprocate along the first direction X, and the second moving unit 22 drives the gripper lifting mechanism 30 to reciprocate along the second direction Y. Figure 1 and Figure 6 As shown, the first moving unit 21 includes a first guiding mechanism 211 and a first driving module 212; the first guiding mechanism 211 is provided in two sets and is used to guide the movement of the second moving unit 22; the first driving module 212 is used to drive the movement of the second moving unit 22; the first driving module 212 is disposed between the two sets of the first guiding mechanism 211.

[0048] This application incorporates a first driving module 212 and two sets of first guiding mechanisms 211 in the first moving unit 21 used to drive the second moving unit 22. The two sets of first guiding mechanisms 211 provide guidance for the movement of the second moving unit 22, thereby ensuring the stability of the movement of the second moving unit 22. At the same time, by setting the first driving module 212 between the two sets of first guiding mechanisms 211, the guidance provided by the two sets of first guiding mechanisms 211 to the second moving unit 22 under the drive of the first driving module 212 is more synchronized, thereby reducing the problem of asynchronous movement of the second moving unit 22 at different positions.

[0049] In some preferred embodiments, such as Figure 1 and Figure 6 As shown, two sets of first guide mechanisms 211 are respectively set at both ends of the second moving unit 22 to greatly reduce the problem of asynchronous movement of the second moving unit 22 at different positions.

[0050] In some preferred embodiments, such as Figure 1 and Figure 6 As shown, the first drive module 212 is centrally positioned between the two sets of first guide mechanisms 211, so that the two sets of first guide mechanisms 211 provide relatively synchronized guidance to the second moving unit 22 under the drive of the first drive module 212; especially when the two sets of first guide mechanisms 211 are respectively positioned at both ends of the second moving unit 22, it can ensure that the two sets of first guide mechanisms 211 provide synchronized guidance to the second moving unit 22 under the drive of the first drive module 212, avoiding the problem of different movement speeds at both ends of the second moving unit 22 under the drive of the first drive module 212.

[0051] As one embodiment of the first driving module 212, such as Figure 1 and Figure 6As shown, the first drive module 212 includes a first drive device 2121 and a first transmission unit 2122; wherein, the first drive device 2121 is fixedly set relative to the frame 100 and is used to drive the first transmission unit 2122 to drive the second moving unit 22, so that the setting position of the first drive device 2121 is more flexible, and when the first drive device 2121 is set on a relatively stable frame 100, it can provide a relatively stable driving force for the second moving unit 22, so that the entire moving mechanism 20 can drive the gripper lifting mechanism 30 more stably.

[0052] As one embodiment of the first guiding mechanism 211, such as Figures 4 to 9 As shown, the first guiding mechanism 211 includes a first guide rail 2111a, a second guide rail 2112a, a first slider 2111b, and a second slider 2112b; the first guide rail 2111a and the second guide rail 2112a are fixedly disposed relative to the frame 100 and extend along the first direction X; at least one of the first slider 2111b and the second slider 2112b are provided, for example, one, two, three, five, etc.; the second moving unit 22 is disposed on at least one first slider 2111b and at least one second slider 2112b; the first slider 2111b is integrally formed or machined with the first guide rail 2111a and the second slider 2112b. The second guide rail 2112a is adapted to the first groove 2111b-1, and the second slider 2112b is integrally formed or machined with the second groove 2112b-1 adapted to the first guide rail 2111a and the second guide rail 2112a; the first slider 2111b is adapted to the first guide rail 2111a; the second slider 2112b is adapted to the second guide rail 2112a, the first guide rail 2111a is located on the first side of the first slider 2111b and the second slider 2112b, and the second guide rail 2112a is located on the side of the first slider 2111b and the second slider 2112b opposite to the first guide rail 2111a. This application, by placing at least two sliders between two guide rails, allows adjustment of the installation position of the two sliders so that the opposite sides of the two sliders abut against the two guide rails respectively, preventing the second moving unit 22 from swaying during movement under the guidance of the first guide mechanism 211.

[0053] In other embodiments, the first slider 2111b is adapted to the second guide rail 2112a; the second slider 2112b is adapted to the first guide rail 2111a.

[0054] In some other embodiments, the first slider 2111b is adapted to the first guide rail 2111a and the second guide rail 2112a; the second slider 2112b is adapted to the first guide rail 2111a and the second guide rail 2112a.

[0055] As one embodiment of the first driving device 2121, such as Figure 1 and Figure 6 As shown, the first driving device 2121 is a first motor, which is fixedly mounted relative to the frame 100; the first transmission unit 2122 includes a first driving pulley 2122a, a first driven pulley 2122b, and a first belt 2122c. The first driven pulley 2122b is pivotally mounted on the frame 100, and the first belt 2122c is sleeved on and adapted to the outer periphery of the first driving pulley 2122a and the first driven pulley 2122b; the first motor drives the first driving pulley 2122a to rotate the first belt 2122c while simultaneously driving the first driven pulley 2122b to rotate; the first belt 2122c between the first driving pulley 2122a and the first driven pulley 2122b is arranged in a direction parallel to the first guide rail 2111a, and the second moving unit 22 is mounted on the first belt 2122c. Therefore, when the first motor is driven, the second moving unit 22 can be driven to reciprocate along the extension direction of the first guide rail 2111a and the second guide rail 2112a via the first belt 2122c; moreover, the first transmission unit 2122 adopts a pulley belt transmission structure, which can reduce costs, and compared with the worm gear transmission unit, it has less resistance, does not require a high-power or high-speed motor, and is less likely to cause the motor to burn out due to high load operation.

[0056] When the first drive device 2121 is the first motor, one implementation method for fixing the first drive device 2121 relative to the frame 100 is as follows: Figure 2 , Figure 6 and Figure 8 As shown, the base of the first motor is mounted on the first mounting base 213; the first drive pulley 2122a is pivotally mounted on the first mounting base 213 and is driven to rotate by the first motor; the first mounting base 213 is mounted on the frame 100 so that by selecting the mounting position and shape of the first mounting base 213, the frame 100 can be prevented from obstructing the transmission of the first transmission unit 2122.

[0057] As another way to implement the first drive device 2121 being fixed relative to the frame 100, the first drive device 2121 is directly mounted on the frame 100.

[0058] As one embodiment of the first driven pulley 2122b being pivotally mounted on the frame 100, such as Figure 6 As shown, the first driven pulley 2122b is pivotally mounted on the second mounting base 214, which is mounted on the frame 100. That is, the first driven pulley 2122b is pivotally mounted on the frame 100 via the second mounting base 214.

[0059] In some preferred embodiments, such as Figure 9As shown, at least one of the first groove 2111b-1 and the second groove 2112b-1 is an annular groove, and the cross-section of at least one of the first groove 2111b-1 and the second groove 2112b-1 is arc-shaped. At least one of the first slider 2111b and the second slider 2112b is rotatably arranged relative to the second moving unit 22 around the central axis of the annular groove. The arrangement direction of the first slider 2111b and the second slider 2112b is not parallel to the extension direction of the first lead screw, so that the opposite sides of the first slider 2111b and the second slider 2112b respectively abut against the first guide rail 2111a and the second guide rail 2112a, avoiding the second moving unit 22 from swaying during movement under the guidance of the first guide mechanism 211; and ensuring that the first slider 2111b and the second slider 2112b move smoothly along the extension direction of the first guide rail 2111a and the second guide rail 2112a.

[0060] In some embodiments, the first direction X is a straight line direction.

[0061] In another embodiment of the first drive module 212, the first drive module 212 includes a drive motor and a gear rack that are adapted to each other. The rack is fixedly disposed relative to the frame 100 and extends along the first direction X. The base of the drive motor is fixedly disposed relative to the first guide mechanism 211, and the drive gear rotates around its central axis. When the first guide mechanism 211 includes a guide rail and a slider that are adapted to each other, the base of the drive motor is fixedly disposed relative to the slider, the guide rail is fixedly disposed relative to the frame 100 and disposed along the first direction X, and the second moving unit 22 is fixedly disposed relative to the slider. When the drive motor drives the gear to rotate, the gear rolls along the extension direction of the rack, while simultaneously driving the drive motor and the slider to reciprocate along the extension direction of the guide rail. The direction of motion depends on the rotation direction of the drive motor.

[0062] As another embodiment of the first guiding mechanism 211, the first guiding mechanism 211 includes an "I"-shaped guide rail and an "I"-shaped slider adapted to the "I"-shaped guide rail. The "I"-shaped guide rail is arranged along a first direction X and is mounted on the frame 100; the second moving unit 22 is disposed on the "I"-shaped slider.

[0063] In another embodiment of the first guiding mechanism 211, the first guiding mechanism 211 includes a mutually adapted optical rod and a sleeved slider sleeved on the outer periphery of the optical rod. The optical rod is arranged along a first direction X and mounted on the frame 100; the second moving unit 22 is disposed on the sleeved slider. Compared with the first embodiment of the first guiding mechanism 211, the fitting clearance of the first guiding mechanism 211 in this embodiment is larger.

[0064] In some preferred embodiments, such as Figure 1 , Figure 3 , Figure 6 , Figure 8 and Figure 13 As shown, the moving mechanism 20 for the overhead crane also includes a second moving unit 22; the first moving unit 21 drives the second moving unit 22 to reciprocate along a first direction; the second moving unit 22 drives the gripper lifting mechanism 30 to reciprocate along a second direction; the first direction and the second direction are not parallel, so that the gripper lifting structure can move in the plane formed by the first direction and the second direction under the drive of the first moving unit 21 and the second moving unit 22.

[0065] As one embodiment of the second moving unit 22, such as Figure 13 and Figure 14 As shown, the second moving unit 22 includes a second guiding mechanism 221 and a second driving module 222. The second guiding mechanism 221 is used to provide guidance for the movement of the gripper lifting mechanism 30.
