Description

Technical Field

[0001] The utility model belongs to the technical field of workpiece transportation, and more particularly relates to a clamping mechanism and a transportation device. Background Art

[0002] When transporting workpieces, a clamping mechanism is usually used to clamp the workpieces. At present, in order to be able to clamp workpieces of different sizes, some clamping mechanisms can use a gear and rack to drive the clamping block to move. However, there is an assembly gap when the rack and the gear are engaged, which makes the assembly and adjustment between the rack, the gear and the clamping block more difficult. When the rack drives the clamping block to move, it is easy for the rack and the gear to get stuck with each other, or the rack and the clamping block to get stuck with each other due to assembly errors and other reasons, which affects the service life of the clamping mechanism.

Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more of such features.

[0042] Combine Figure 1 and Figure 2 A clamping mechanism includes a bracket 100, a first clamping assembly 200, a second clamping assembly 300, a driving assembly 400 and a first floating connection assembly 500.

[0043] The first clamping assembly 200 and the second clamping assembly 300 are disposed relative to each other on the bracket 100 and can move closer to or farther away from each other. Specifically, when the first clamping assembly 200 and the second clamping assembly 300 are closer to each other, the first clamping assembly 200 and the second clamping assembly 300 can cooperate to clamp the workpiece; when the first clamping assembly 200 and the second clamping assembly 300 are farther away from each other, the first clamping assembly 200 and the second clamping assembly 300 can cooperate to release the workpiece.

[0044] Further, see Figure 3 and Figure 4 The drive assembly 400 may include a drive member 410, a gear 420, and a first rack 430. The drive member 410 is disposed on the bracket 100 and is drivingly connected to the gear 420 so that the gear 420 can rotate. The first rack 430 is engaged with the gear 420. When the drive member 410 drives the gear 420 to rotate, the first rack 430 can move in a linear direction.

[0045] The first rack 430 is connected to the first clamping assembly 200 via a first floating connection assembly 500 . The first rack 430 is used to drive the first clamping assembly 200 to move.

[0046] Specifically, when the first rack 430 moves in a straight line direction, the first clamping assembly 200 can be driven to move via the first floating connection assembly 500 , so that the first clamping assembly 200 moves closer to or away from the second clamping assembly 300 .

[0047] In the present application, since the first rack 430 is connected to the first clamping assembly 200 through the first floating connection assembly 500, the connection between the first rack 430 and the first clamping assembly 200 is a floating connection, which avoids the gear 420, the rack and the first clamping assembly 200 from getting stuck with each other due to assembly accuracy and debugging accuracy, such as insufficient parallelism between the first rack 430 and the first clamping assembly 200, thereby reducing the difficulty of assembly. At the same time, the first floating connection assembly 500 allows a certain correction space between the first rack 430 and the first clamping assembly 200, which can extend the service life of the drive assembly 400 and the first clamping assembly 200.

[0048] For example, see Figure 1 In some embodiments, the first clamping assembly 200 and the second clamping assembly 300 may be arranged relatively on the bracket 100 along a first direction, the gear 420 may be located between the first clamping assembly 200 and the second clamping assembly 300, the first rack 430 may be located on one side of the gear 420 in the second direction, and the first direction may be perpendicular to the second direction.

[0049] Specifically, when the gear 420 rotates, it drives the first rack 430 to move along the first direction, and the first rack 430 drives the first clamping assembly 200 to move along the first direction.

[0050] See Figure 2 The first floating connection assembly 500 may include a first pin 510 and a first pin hole 520 cooperating with the first pin 510, wherein one of the first pin 510 and the first pin hole 520 is arranged on the first rack 430, and the other is arranged on the first clamping assembly 200, the first pin 510 is located in the first pin hole 520, and there is a first gap between the first pin 510 and the first pin hole 520 at least in the moving direction of the first clamping assembly 200.

[0051] For example, in some embodiments, the first pin 510 may be disposed on the first rack 430 , and the first pin hole 520 may be disposed on the first clamping assembly 200 . During assembly, the first pin 510 is inserted into the first pin hole 520 .

[0052] It is understood that, because there is a first gap (not shown) between the first pin 510 and the first pin hole 520, at least in the direction of movement of the first clamping assembly 200, the first pin 510 and the first pin hole 520 are able to move relative to each other, that is, there is a certain amount of space for correction between the first pin 510 and the first pin hole 520. Furthermore, when the first clamping assembly 200 is connected to the first rack 430 via the first floating connection assembly 500, it only requires the first pin 510 to be installed in the first pin hole 520, which simplifies assembly and reduces debugging.

[0053] Of course, in some embodiments, a first gap may also be formed between the first pin 510 and the first pin hole 520 in other directions.

[0054] Furthermore, to improve the stability of the movement of the first gear 420, the drive assembly 400 further includes a first guide structure 450. The first rack 430 is disposed on the bracket 100 via the first guide structure 450. The first guide structure 450 is configured to guide the first rack 430 during its movement. Specifically, the first guide structure 450 guides the first rack 430 when it moves in a straight line, such as the first direction. The first guide structure 450 may be a guide rail structure.

[0055] Furthermore, in order to facilitate the installation between the first rack 430, the first guide structure 450 and the first pin 510, the drive assembly

[0056] 400 may further include a first mounting member 460 , which is disposed on the bracket 100 through a first guide structure 450 , and the first rack 430 and the first pin 510 are disposed on the first mounting member 460 .

[0057] Specifically, a first side surface of the first rack 430 may be engaged with the gear 420 , and a second side surface of the first rack 430 adjacent to the first side surface is connected to the first mounting member 460 .

[0058] See Figure 1 In some embodiments, the second clamping assembly 300 can also move relative to the bracket 100 , that is, the second clamping assembly 300 can actively move closer to or away from the first clamping assembly 200 .

[0059] Specifically, the driving assembly 400 may also include a second rack 440, the first rack 430 and the second rack 440 are respectively located on both sides of the gear 420, and the clamping mechanism may also include a second floating connection assembly 600, and the second rack 440 is connected to the second clamping assembly 300 through the second floating connection assembly 600.

[0060] For example, the first rack 430 and the second rack 440 may be located on both sides of the gear 420 along the second direction and respectively meshed with the gear 420. When the gear 420 rotates, the first rack 430 and the second rack 440 may move in opposite directions.

[0061] See Figure 2The second floating connection component 600 may include a second pin 610 and a second pin hole 620 that cooperates with the second pin 610, wherein one of the second pin 610 and the second pin hole 620 is set on the second rack 440, and the other is set on the second clamping component 300, the second pin 610 is located in the second pin hole 620, and there is a second gap (not shown in the figure) between the second pin 610 and the second pin hole 620 at least in the moving direction of the second clamping component 300.

[0062] For example, in some embodiments, the second pin 610 may be disposed on the second rack 440 , and the second pin hole 620 may be disposed on the second clamping assembly 300 . During assembly, the second pin 610 is inserted into the second pin hole 620 .

[0063] As can be understood, since there is a second gap between the second pin 610 and the second pin hole 620, at least in the direction of movement of the second clamping assembly 300, the second pin 610 and the second pin hole 620 are able to move relative to each other, that is, there is a certain amount of space for deviation correction between the second pin 610 and the second pin hole 620. Furthermore, when the second clamping assembly 300 is connected to the second rack 440 via the second floating connection assembly 600, it only requires the second pin 610 to be installed in the second pin hole 620, which simplifies assembly and reduces debugging.

[0064] Furthermore, to improve the stability of the movement of the second gear 420, the drive assembly 400 also includes a second guide structure 470. The second rack 440 is disposed on the bracket 100 via the second guide structure 470. The second guide structure 470 is used to guide the second rack 440 during its movement. Specifically, the second guide structure 470 guides the second rack 440 when it moves in a straight line, such as the first direction. The second guide structure 470 can be a guide rail structure.

[0065] Furthermore, in order to facilitate the installation between the second rack 440, the second guide structure 470 and the second pin 610, the drive assembly 400 may also include a second mounting member 480, which is arranged on the bracket 100 through the second guide structure 470, and the second rack 440 and the second pin 610 are arranged on the second mounting member 480.

[0066] Specifically, a first side surface of the second rack 440 may be engaged with the gear 420 , and a second side surface of the second rack 440 adjacent to the first side surface is connected to the second mounting member 480 .

[0067] See Figure 2The first clamping assembly 200 may include a first clamping structure 210 and a third guide structure 220. The first clamping structure 210 is arranged on the bracket 100 through the third guide structure 220, and the first clamping structure 210 is connected to the first floating connection assembly 500 so that the first clamping structure 210 can approach or move away from the second clamping assembly 300.

[0068] Specifically, the first clamping structure 210 and the second clamping assembly 300 can mutually clamp or release a workpiece. The third guide structure 220 provides guidance when the first clamping structure moves. For example, the third guide structure can provide guidance when the first clamping structure moves in a first direction. The third guide structure 220 can be a guide rail.

[0069] The first clamping structure 210 may include a first clamping member 211 and a first clamping connector 212 arranged on both sides of the gear 420. The first clamping members 211 are respectively arranged on the bracket 100 through the corresponding third guide structure 220, and the first clamping members 211 are connected through the first clamping connector 212.

[0070] It can be understood that in some embodiments, in order to improve the stability of the first clamping structure in clamping the workpiece, the first clamping structure 210 may be relatively provided with first clamping members 211, and the relatively provided first clamping members 211 are connected by a first clamping connector 212, so that the first clamping members 211 can move synchronously.

[0071] Furthermore, in some embodiments, in order to facilitate the disposition of the first pin hole 520 and facilitate the disposition of the first pin column 510 in the first pin hole 520 , the first clamping connector 212 may be provided with a first pin hole 520 .

[0072] Furthermore, in some embodiments, when the gear 420 is engaged with the second rack 440 , in order to prevent the second rack 440 from interfering with the first clamping connector 212 when moving, a first avoidance space 213 for avoiding the second rack 440 may be provided between the first clamping connector 212 and the bracket 100 .

[0073] See Figure 5 The first clamping member 211 may also include a first clamping plate 2111 and a first support plate 2112. One end of the first clamping plate 2111 is set on the bracket 100 through the third guide structure 220, and the other end of the first clamping plate 2111 is connected to the first support plate 2112. The first support plate 2112 is used to support the workpiece clamped by the first clamping plate 2111.

[0074] Specifically, when the first clamping plate cooperates with the second clamping assembly to clamp the workpiece, the first support plate 2112 can support the lower surface of the workpiece to prevent the workpiece from separating from the first clamping plate.

[0075] See Figure 2 The second clamping assembly 300 may include a second clamping structure 310 and a fourth guide structure 320. The second clamping structure 310 is arranged on the bracket 100 through the fourth guide structure 320, and the second clamping structure 310 is connected to the second floating connection assembly 600 so that the second clamping structure 310 can approach or move away from the first clamping assembly 200.

[0076] Specifically, the second clamping structure 310 and the first clamping structure can mutually clamp or release the workpiece. The fourth guide structure 320 provides guidance when the second clamping structure moves. For example, the fourth guide structure can provide guidance when the second clamping structure moves in the first direction. The fourth guide structure 320 can be a guide rail.

[0077] See Figure 2 The second clamping structure 310 may include a second clamping member 311 and a second clamping connector 312 arranged on both sides of the gear 420. The second clamping members 311 are respectively arranged on the bracket 100 through the corresponding fourth guide structure 320, and the second clamping members 311 are connected through the second clamping connector 312.

[0078] It can be understood that in some embodiments, in order to improve the stability of the second clamping structure in clamping the workpiece, the second clamping structure 310 may be relatively provided with second clamping members 311, and the relatively provided second clamping members 311 are connected by a second clamping connector 312, so that the second clamping members 311 can move synchronously.

[0079] Furthermore, in some embodiments, in order to facilitate the disposition of the second pin hole 620 and facilitate the disposition of the second pin column 610 in the second pin hole 620 , a second pin hole 620 may be provided on the second clamping connector 312 .

[0080] Furthermore, in some embodiments, when the gear 420 is engaged with the second rack 440 , in order to prevent the second rack 440 from interfering with the second clamping connector 312 when moving, a second avoidance space 313 may be provided between the second clamping connector 312 and the bracket 100 to avoid the first rack 430 .

[0081] The second clamping member 311 may also include a second clamping plate and a second support plate. One end of the second clamping plate is set on the bracket 100 through the fourth guide structure 320, and the other end of the second clamping plate is connected to the second support plate. The second support plate is used to support the workpiece clamped by the second clamping plate.

[0082] Specifically, when the first clamping plate and the second clamping plate cooperate to clamp the workpiece, the second support plate can support the lower surface of the workpiece to prevent the workpiece from separating from the second clamping plate.

[0083] See Figure 1 The clamping mechanism may further include a first latch assembly 700, which is arranged on the bracket 100 and corresponds to the end position of the first clamping assembly 200 moving in the direction close to the second clamping assembly 300. The first clamping assembly 200 is provided with a first positioning hole 230, and the first latch assembly 700 is used to cooperate with the first positioning hole 230 to fix the first clamping assembly 200.

[0084] Specifically, when the first clamping assembly 200 moves toward the end position close to the second clamping assembly 300 and cooperates with the second clamping assembly 300 to clamp the workpiece, the first pin assembly 700 can cooperate with the first positioning hole 230 set on the first clamping assembly 200 to fix the first clamping assembly 200, that is, to fix the first clamping assembly 200 at the end position.

[0085] It can be understood that since the first rack 430 that drives the first clamping assembly 200 to move is connected to the gear 420 by meshing, when it is necessary to transfer the workpiece clamped by the clamping mechanism, the workpiece may generate a reaction force in the clamping direction on the first clamping assembly 200 during the movement. At this time, if the reaction force is large, it will damage the meshing between the first rack 430 and the gear 420, and in severe cases it may cause damage to the gear 420 and the tooth block on the first gear 420, causing the first rack 430 to disengage from the gear 420, thereby causing the workpiece moved by the first clamping assembly 200 to fall.

[0086] In some embodiments, the first latch assembly 700 may include a latch driver 410 and a pin. The latch driver 410 is disposed on the bracket 100 and is drivingly connected to the pin. When the first clamping assembly 200 moves toward the second clamping assembly 300 to its final position and cooperates with the second clamping assembly 300 to clamp the workpiece, the latch driver 410 can drive the pin into the first positioning hole 230 to secure the first clamping assembly 200. The latch driver 410 may be a pneumatic cylinder.

[0087] In some embodiments, the first positioning hole 230 may be provided on the first clamping plate 2111. For example, to facilitate the provision of the first positioning hole 230 on the first clamping plate 2111, the first clamping plate 2111 may include a first connecting portion 21112 and a first clamping portion 21111. The first clamping portion 21111 is connected to the third guide structure 220 via the first connecting portion 21112. The first clamping portion 21111 is used to clamp the space, and the first positioning hole 230 may be provided on the first connecting portion 21112.

[0088] See Figure 1When the second clamping assembly 300 is driven by the second rack 440, the clamping mechanism may further include a second latch assembly 800. The second latch assembly 800 is arranged on the bracket 100 and corresponds to the end position of the second clamping assembly 300 moving in the direction close to the first clamping assembly 200. A second positioning hole 330 is provided on the second clamping assembly 300, and the second latch assembly 800 is used to cooperate with the second positioning hole 330 to fix the second clamping assembly 300.

[0089] Specifically, when the second clamping assembly 300 moves toward the end position and cooperates with the second clamping assembly 300 to clamp the workpiece, the second pin assembly 800 can cooperate with the second positioning hole 330 set on the second clamping assembly 300 to fix the second clamping assembly 300, that is, fix the second clamping assembly 300 at the end position.

[0090] It can be understood that since the second rack 440 that drives the second clamping assembly 300 to move is connected to the gear 420 by meshing, when it is necessary to transfer the workpiece clamped by the clamping mechanism, the workpiece may generate a reaction force in the clamping direction on the second clamping assembly 300 during the movement. At this time, if the reaction force is large, it will damage the meshing between the second rack 440 and the gear 420, and in severe cases it may cause damage to the gear 420 and the tooth blocks on the second gear 420, causing the second rack 440 to disengage from the gear 420, thereby causing the workpiece moved by the second clamping assembly 300 to fall.

[0091] In some embodiments, the second latch assembly 800 may include a latch driver 410 and a pin. The latch driver 410 is disposed on the bracket 100 and is drivingly connected to the pin. When the second clamping assembly 300 moves toward the second clamping assembly 300 to an end position to cooperate with the second clamping assembly 300 to clamp the workpiece, the latch driver 410 can drive the pin into the second positioning hole 330 to secure the second clamping assembly 300. The latch driver 410 may be a cylinder.

[0092] In some embodiments, the second positioning hole 330 may be provided on the second clamping plate. For example, to facilitate the provision of the second positioning hole 330 on the second clamping plate, the second clamping plate may include a second connecting portion and a second clamping portion, the second clamping portion being connected to the fourth guide structure 320 via the second connecting portion, the second clamping portion being used to clamp the space, and the second positioning hole 330 may be provided on the second connecting portion.

[0093] See Figure 1 The clamping mechanism may further include a visual mechanism 900 , which is disposed on the bracket 100 and close to an edge of the bracket 100 , so that the visual mechanism 900 is exposed to detect the position of the workpiece.

[0094] It is understandable that the clamping mechanism can detect the position of the workpiece through the visual mechanism 900 so that the first clamping assembly 200 and the second clamping assembly 300 can cooperate to accurately clamp the workpiece.

[0095] The clamping mechanism may further include a height sensor 1000 , which is disposed on the bracket 100 and is used to detect the distance between the height sensor 100 and the workpiece.

[0096] The clamping mechanism may further include a photoelectric sensor 1100 . The photoelectric sensor 1100 is disposed on the bracket 100 and is close to the gear 420 . The photoelectric sensor 1100 is used to detect whether there is a workpiece under the clamping mechanism.

[0097] It can be understood that in some embodiments, the gear 420 drives the first clamping component 200 and the second clamping component 300 to move through the first rack 430 and the second rack 440 respectively, so the gear 420 is generally set at the middle position between the first clamping component 200 and the second clamping component 300. Therefore, the photoelectric sensor 1100 is set close to the gear 420 so that the photoelectric sensor 1100 can also be located near the middle position between the first clamping component 200 and the second clamping component 300. In this way, when the photoelectric sensor 1100 detects a workpiece, it can facilitate the first clamping component 200 and the second clamping component 300 to clamp the workpiece, avoid excessive adjustment of the position of the clamping mechanism, and improve efficiency.

[0098] In addition, the present application also provides a transport device, including a displacement mechanism and a clamping mechanism of an embodiment of the present application, and the displacement mechanism is drivingly connected to the bracket 100 to drive the clamping mechanism to move.

[0099] Specifically, the displacement mechanism can drive the clamping mechanism to move to the area where the workpiece is located to clamp the workpiece, and can also drive the clamping mechanism to transfer the clamped workpiece. The displacement mechanism can be a robot or an overhead crane.

[0100] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of some utility models should be included in the scope of protection of some utility models.
