Description

Technical Field

[0001] This utility model relates to the technical field of claw machine accessories, and in particular to a claw control device and overhead crane that are easy to control. Background Technology

[0002] The claw and the overhead crane are the core components of a claw machine, and the machine's operation depends on their movement. Existing overhead crane modules typically include two guide rails positioned on either side of the top of the prize compartment. The crane moves along these two rails. Two additional guide rails on the crane control device move along these two rails, allowing the claw to move freely along three axes within the prize compartment. However, controlling this type of crane only allows control of the claw control device's movement; it cannot further restrict the device's actions based on its position within the prize compartment. Determining the claw control device's position requires monitoring the number of rotations of the motor controlling its movement. This control method introduces parameters that need to be calculated and measured, making programming cumbersome and prone to errors. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a gripper control device and overhead crane that are easy to control. It eliminates the need for real-time detection and calculation of the motor's rotation count, and can further control or restrict the gripper's actions based on its current position within the gift compartment.

[0004] According to one aspect of this application, a gripper control device that is easy to control is provided, including a device housing, a first detection module disposed on the device housing, the first detection module being used to issue a first control signal when the device housing passes through a preset position, a first moving module disposed on the upper part of the device housing for driving the device housing to move on a first guide rail, and a take-up and release module disposed in the middle part of the device housing for connecting with the gripper.

[0005] This utility model's gripper control device, by adding a first detection module, can detect whether the gripper control device has passed a preset position and issue a first control signal. This eliminates the need for real-time calculation of the motor's rotation count, effectively avoiding misjudgments caused by calculation errors. Furthermore, the introduction of a new control signal simplifies programming and makes the gripper control device more convenient to operate. For example, in practical use, a trigger module matching the first detection module can be installed in the middle of the gift compartment or the crane, dividing the gift compartment into two parts. When the gripper control device moves from one part to the other, it triggers the first detection module to issue a first control signal. Similarly, when the gripper control device returns, it also triggers the first detection module to issue a first control signal. This first control signal determines the gripper control device's position within the gift compartment, allowing for control of its operation based on its position, such as restricting the gripper's downward movement.

[0006] In some possible implementations, a second detection module is provided on the device housing, which is used to detect whether the device housing has moved to the extreme positions on both sides of the first guide rail.

[0007] Therefore, this configuration allows the second detection module to detect whether the current device housing has reached both ends of the first guide rail. In existing technology, whether the gripper control device has reached both ends of the first rail is typically detected by a detection module mounted on the crane. This configuration increases the number of components on the crane. Due to the crane's length, control components and other modules are usually only located on one side. Therefore, the detection module on the crane is only located on one side, making it impossible to detect whether the gripper control device has reached the end position on the other side, thus hindering program design. Furthermore, this configuration concentrates the crane's weight at one end, affecting its balance on the second guide rail. Therefore, the side of the crane without control components usually requires an additional structure to maintain the connection between that side and the guide rail, preventing the crane from tilting when the gripper control device moves to the side with control components. This configuration results in a larger structure on the side of the crane without control components, affecting the crane's configuration and thus the movement range of the gripper control device within the gift compartment. Therefore, by setting a second detection module on the device housing, it is possible not only to better detect whether the device housing has reached the extreme positions on both sides of the first guide rail, but also to reduce the number of structures on one side of the crane, improve the crane's balance and installation stability, and effectively increase the range of movement of the gripper control device during movement, reducing the dead angle of gripper lowering.

[0008] In some possible implementations, the second detection module includes a second detection unit and a third detection unit, which are respectively disposed on both sides of the device housing in the direction of movement of the first guide rail.

[0009] Therefore, with this configuration, the second and third detection units installed on the device housing can be used to detect whether the gripper control device has reached the extreme positions on both sides when it moves on the first guide rail.

[0010] In some possible implementations, the second detection unit and the third detection unit are configured as microswitches.

[0011] Therefore, with this configuration, when the gripper control device moves to the extreme positions on both sides, it will trigger the pressing of the micro switch, thereby sending a control signal. The control program can then be designed based on this control signal, making the design of the control program more convenient and efficient.

[0012] In some possible implementations, the first detection module includes a first detection unit disposed on the top of the device housing.

[0013] Thus, with this configuration, the top of the gift compartment or the top of the overhead crane can be detected using the first detection unit located on the top of the device housing.

[0014] In some possible implementations, the first detection unit is an electromagnetic induction module.

[0015] Therefore, by setting it up in this way, the electromagnetic induction module can be used to sense structures such as magnets, thereby emitting the first control signal.

[0016] According to another aspect of this application, a crane is provided, including a support frame, on which a second moving module is disposed, the second moving module being used to drive the support frame to move on a second guide rail. The support frame includes a first side plate and a second side plate, a first guide rail being disposed between the first side plate and the second side plate. A gripper control device as described in the first aspect is disposed on the first guide rail. A connecting rod is disposed between the first side plate and the second side plate, and a trigger module for interacting with the first detection module is disposed on the connecting rod.

[0017] The overhead crane of this invention is equipped with the aforementioned gripper control device, which makes programming more convenient and allows for easier control of the gripper control device.

[0018] In some possible implementations, the first detection module includes an electromagnetic induction module disposed on the top of the device housing, and the trigger module includes a magnet disposed on a connecting rod.

[0019] Therefore, by using this setup, the electromagnetic induction module on the gripper control device can be used in conjunction with the magnet to detect and determine the current position of the gripper control device in the gift compartment, so as to send out the first control signal.

[0020] In some possible implementations, a second detection module is provided on the device housing, which is used to detect whether the device housing has moved to the extreme positions on both sides of the first guide rail.

[0021] Therefore, by setting it up in this way, the number of control elements on the support can be reduced, thereby effectively reducing the weight on one side of the support. This makes the overall crane arrangement on the second guide rail more balanced and stable. At the same time, it can also eliminate the need for the structure on the side of the support where no control elements are set to limit the crane on the second guide rail, thus making the overall crane's gripping blind spot smaller and the movement range of the gripper control device larger.

[0022] In some possible implementations, the second moving module includes a drive module disposed on the first side plate, and a third detection module is also disposed on the first side plate, the third detection module being used to detect whether the bracket has moved to the extreme positions on both sides of the second guide rail;

[0023] The third detection module includes a fourth detection unit and a fifth detection unit, which are respectively located on both sides of the first side plate in the direction of movement of the second guide rail.

[0024] Therefore, with this setup, the third detection module can be used to determine whether the crane has moved to the extreme positions on both sides of the second track, and thus send a signal, making the program easier to write. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings.

[0036] Figure 1 The overall structure of the gripper control device according to one embodiment of the present invention is schematically shown, with reference to... Figure 1 As shown, the gripper control device of this utility model includes a device housing 1, a first detection module 2 is provided on the device housing 1, the first detection module 2 is used to send a first control signal when the device housing 1 passes through a preset position, a first moving module 4 is provided on the upper part of the device housing 1 for driving the device housing 1 to move on the first guide rail 64, and a take-up and release module 5 is provided in the middle part of the device housing 1 for connecting with the gripper.

[0037] Specifically, the shape of the overall device casing 1 can be designed according to actual needs, such as a cuboid shape, a hexagonal prism shape, etc. (Refer to...) Figure 1 As shown, in Figure 1In the illustrated embodiment, the shape of the device housing 1 can be approximately cuboid. The first moving module 4 is disposed on the upper part of the device housing 1, and includes an active roller assembly 41 and an auxiliary roller assembly 42 extending to opposite sides of the device housing 1. The active roller assembly 41 includes an active rotating shaft and rollers disposed at both ends of the active rotating shaft, and the auxiliary roller assembly 42 includes an auxiliary rotating shaft and rollers disposed at both ends of the auxiliary rotating shaft. The rollers on both the active roller assembly 41 and the auxiliary roller assembly 42 are mounted on a first guide rail 64. The active rotating shaft is connected to a drive module for driving the active rotating shaft to rotate, thereby driving the device housing 1 to move on the first guide rail 64. Besides the above embodiment, the first moving module 4 can also be configured with other structures found in the prior art, such as gear and rack meshing or wire drive, etc., and this invention does not limit this.

[0038] The take-up / deployment module 5 is located in the middle of the device housing 1, and includes at least one pulley 51. (See reference...) Figure 1 As shown, in Figure 1 In the illustrated embodiment, only one pulley 51 is provided, and its side is arranged parallel to one side of the housing 1 of the device. A drive module is connected to the rotation center of the pulley 51, thereby directly controlling the rotation of the pulley 51. The gripper's release and take-up ropes are wound around the pulley 51, so that when the drive module drives the pulley 51 to rotate, the lowering and retraction of the gripper can be controlled. Besides the above embodiment, the release and take-up module 5 can also be configured with other structures found in the prior art, such as a combination of multiple pulleys 51, or a cylinder-driven mechanism; this invention does not limit this to any particular configuration.

[0039] The first detection module 2 is used to issue a first control signal when the device housing 1 passes through a preset position. The setting position of the first detection module 2 on the device housing 1 can be arbitrarily set. The setting position of the first detection module 2 on the device housing 1 is related to the structure and setting position of the corresponding trigger module 8 to be detected. It only needs to satisfy the requirement that the first detection module 2 can detect the corresponding structure and issue a first control signal. Specifically, refer to Figure 1 and Figure 2 As shown, in Figure 1 and Figure 2In the illustrated embodiment, the first detection module 2 includes a first detection unit, which is disposed on the top of the device housing 1. Since the overall gripper control device is located at the top of the gift compartment during operation, placing the first detection unit on the top of the device housing 1 allows for better interaction with the corresponding structure on the gift compartment or the overhead crane to identify and issue a first control signal. The first detection unit can be a sensor unit such as an infrared sensor or a photoelectric sensor; this invention does not limit this. Specifically, in this embodiment, the first detection unit adopts an electromagnetic induction module. By providing structures such as magnets on the overhead crane or the top of the gift compartment, the gripper control device can issue a first control signal when it senses the corresponding structure during movement. This makes programming the overall gripper control device more convenient and reduces the probability of errors.

[0040] In existing overhead crane and gripper control devices, whether the gripper control device has reached the two ends of the first track is usually detected by a detection module on the overhead crane. This setup increases the number of components on the overhead crane. Furthermore, due to the long length of the overhead crane, control units and other modules are typically located on only one side. Therefore, the detection module on the overhead crane is only located on one side, making it impossible to detect whether the gripper control device has reached the end position on the other side, thus hindering program design. This setup also concentrates the weight of the overhead crane at one end, affecting its balance when moving on the corresponding second guide rail. Consequently, the side of the overhead crane without control components needs an additional structure for fixing and limiting, thus affecting the movement range of the gripper control device within the gift compartment. Therefore, in some possible embodiments, a second detection module can be provided on the gripper control device. This second detection module is used to detect whether the device housing 1 has moved to the extreme positions on both sides of the first guide rail 64. By setting it up in this way, the module that was originally set on the crane can be set on the gripper control device. This ensures that the gripper control device can detect when it moves to the extreme positions on both sides of the first guide rail 64. At the same time, it can reduce the number of components on the crane, making the crane more balanced. This eliminates the need for an additional structure on the side of the crane where there are no control components, allowing the crane to be installed at a more distant end of the gift compartment. This increases the range of movement of the gripper control device and reduces the dead angle of the gripper when it is lowered.

[0041] Specifically, refer to Figure 2 As shown, in Figure 2In the illustrated embodiment, the second detection module includes a second detection unit 31 and a third detection unit 32. The second detection unit 31 and the third detection unit 32 are respectively disposed on both sides of the first guide rail 64 in the moving direction on the device housing 1. When the overall gripper control device moves to the extreme positions on both sides of the first guide rail 64, the second detection unit 31 or the third detection unit 32 interacts with both ends of the first guide rail 64 on the crane, thereby sending a control signal to indicate that the gripper control device has moved to the extreme positions on both sides of the first guide rail 64. Both the second detection unit 31 and the third detection unit 32 can be sensor units such as infrared sensors or photoelectric sensors; this invention does not limit their use. Specifically, in this embodiment, both the second detection unit 31 and the third detection unit 32 are implemented using microswitches.

[0042] This utility model's gripper control device, by additionally adding a first detection module 2, can detect whether the gripper control device has passed a preset position and issue a first control signal. This eliminates the need for real-time calculation of the motor's rotation count, effectively avoiding misjudgments caused by calculation errors. Furthermore, the introduction of a new control signal simplifies program writing and makes the gripper control device more convenient to operate. For example, in practical use, a trigger module matching the first detection module 2 can be installed in the middle of the gift compartment or the crane, dividing the gift compartment into two parts. When the gripper control device moves from one part of the gift compartment to the other, it triggers the first detection module 2 to issue a first control signal. Similarly, when the gripper control device returns, it also triggers the first detection module 2 to issue a first control signal. This first control signal determines the gripper control device's position within the gift compartment, allowing for control of its operation based on its position, such as restricting the gripper's downward movement.

[0043] Figure 3 The overall structure of the overhead crane according to one embodiment of this utility model is schematically shown, with reference to... Figure 3 As shown, the overhead crane of this utility model includes a support frame 6, on which a second moving module is mounted. The second moving module is used to drive the support frame 6 to move on a second guide rail. The support frame 6 includes a first side plate 61 and a second side plate 62 respectively disposed at both ends of the support frame 6. A first guide rail 64 is disposed between the first side plate 61 and the second side plate 62, and a gripper control device of any of the embodiments described above is disposed on the first guide rail 64. Because the overhead crane is equipped with the gripper control device described above, the programming of the overall overhead crane can be made more convenient when controlling it.

[0044] Meanwhile, the overhead crane is equipped with a trigger module that interacts with the first detection module 2 on the gripper control device. Specifically, a connecting rod 63 is provided between the first side plate 61 and the second side plate 62 of the overhead crane, and the trigger module is mounted on the connecting rod 63. Since the first guide rail 64 is located between the first side plate 61 and the second side plate 62, and the connecting rod 63 is also located between the first side plate 61 and the second side plate 62, when the gripper control device moves on the overhead crane, it will send a first control signal when it passes the trigger module on the connecting rod 63. The specific structure of the trigger module can be designed according to the components used in the first detection module 2. For details, refer to... Figure 3 As shown, in Figure 3 In the illustrated embodiment, the trigger module is a magnet, which is mounted on the connecting rod 63. The first detection unit corresponding to the first detection module 2 is an electromagnetic induction module. Therefore, when the gripper control device moves on the crane, it passes the magnet on the connecting rod 63, triggering an electromagnetic induction signal from the electromagnetic induction module. This simplifies the programming of the crane and gripper control device control programs.

[0045] In addition, in some possible implementations, a second detection module is provided on the housing 1 of the gripper control device. This design can reduce the number of control elements on the support 6 of the crane, thereby effectively reducing the weight on one side of the support 6. This makes the overall crane arrangement on the second guide rail more balanced and stable. At the same time, it can also eliminate the structure on the side of the support 6 where no control elements are provided to limit the crane on the second guide rail, thereby making the overall crane's gripping blind spot smaller and the movement range of the gripper control device larger.

[0046] In some possible implementations, the second moving module may include a drive module disposed on the first side plate 61. The first side plate 61 also has a third detection module for detecting whether the support 6 has moved to the extreme positions on both sides of the second guide rail. Specifically, the second moving module may be disposed on the first side plate 61 or the second side plate 62. The first side plate 61 and the second side plate 62 are not necessarily designated as side plates on a fixed side of the overhead crane; this invention does not limit this. Specifically, refer to... Figure 4As shown, the second moving module includes a driving wheel 71 and a first auxiliary wheel 72 mounted on the first side plate 61. The driving wheel 71 is connected to a drive module for driving its rotation. The first auxiliary wheel 72 is driven by a belt to rotate synchronously with the driving wheel 71. The second side plate 62 is equipped with a second auxiliary wheel 73 and a third auxiliary wheel 74. The second auxiliary wheel 73 rotates synchronously with the driving wheel 71 via a long connecting shaft 75, and the third auxiliary wheel 74 is driven by a belt to rotate synchronously with the second auxiliary wheel 73. During installation, the driving wheel 71, the first auxiliary wheel 72, the second auxiliary wheel 73, and the third auxiliary wheel 74 are all mounted on the second guide rail, thereby controlling the movement of the overhead crane on the second guide rail.

[0047] For the third detection module, since the main components are all located on the first side plate 61, the third detection module is also located on the first side plate 61. Specifically, the third detection module includes a fourth detection unit 91 and a fifth detection unit 92. The fourth detection unit 91 and the fifth detection unit 92 are respectively located on both sides of the first side plate 61 in the moving direction of the second guide rail, thereby enabling them to detect whether the bracket 6 has moved to the extreme positions on both sides of the second guide rail. (Refer to...) Figure 4 As shown, in Figure 4 In the illustrated embodiment, both the fourth detection unit 91 and the fifth detection unit 92 employ microswitches, and are respectively positioned on both sides of the first side plate 61. This design effectively enables the third detection module to determine whether the crane has moved to the extreme positions on either side of the second track and triggers a signal, making the program easier to write.

[0048] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
