Description

Technical Field

[0001] The present application relates to the field of handling and transferring equipment, and specifically to a handling mechanism and a transferring device. Background Art

[0002] During the production process, it is often necessary to use a handling mechanism to clamp and transport materials with a rectangular structure. For example, during the production of lithium batteries, it is necessary to transport battery cell modules.

[0003] The existing transport mechanism for transporting battery cell modules generally includes a mounting base, a clamping assembly mounted on the mounting base, and two limit plates. The two limit plates are located on opposite sides of the clamping assembly. The clamping assembly is used to clamp the side walls of the battery cell module from the width direction of the battery cell module, and the two limit plates press the two ends of the battery cell module from the length direction of the battery cell module. In the existing transport mechanism, both limit plates are driven by cylinders. The main problem is that during rapid transport, if an emergency stop occurs, the battery cell module will push against one of the limit plates due to inertia, and the cylinder driving the limit plate will retract after being compressed, causing the limit plate to retreat, which may eventually cause the battery cell module to loosen and fall. Utility Model Content

[0004] In order to solve the above technical problems, the present application provides a screen printing device, which adopts the following technical solutions:

[0005] A transport mechanism includes a mounting base, a clamping assembly, a first limit plate, a second limit plate, a screw drive module, and a cylinder drive module, wherein:

[0006] The clamping assembly is arranged on the mounting seat;

[0007] The first limit plate is slidably connected to the mounting base and is located on the first side of the clamping assembly. The first limit plate is transmission-connected to a screw drive module provided on the mounting base. The screw drive module is used to drive the first limit plate to move toward or away from the clamping assembly along a first direction.

[0008] The second limit plate is slidably connected to the mounting base and is located on the second side of the clamping assembly. The second limit plate is transmission-connected to the cylinder drive module arranged on the mounting base. The cylinder drive module is used to drive the second limit plate to move toward or away from the clamping assembly along the first direction.

[0009] The conveying mechanism provided by the present application has a first limit plate located on one side of the clamping assembly driven by a screw drive module. During the material handling process, the direction of the conveying mechanism is adjusted so that the first limit plate is in front of the material. In this way, when an emergency stop occurs during the handling process, the first limit plate is subjected to the inertial push of the material. Since the first limit plate is driven by the screw drive module, and the screw drive module does not retract after being compressed, the material is prevented from loosening or falling. The conveying mechanism of the present application is suitable for the handling of materials with rectangular structures such as battery cell modules. In order to increase the load capacity, the conveying mechanism needs to reduce its own weight as much as possible. The weight of the screw drive module of the same specification is greater than that of the cylinder drive module. Therefore, only setting the driving part of the first limit plate to the screw drive module can also make the own weight of the conveying mechanism meet the requirements and avoid affecting the load capacity of the conveying mechanism.

[0010] In some embodiments, the screw drive module includes a first slide rail, a first transmission member, a first motor, a first screw and a first sleeve, wherein: the first slide rail and the first screw are arranged on a mounting seat along a first direction, the first sleeve is threaded onto the first screw, and the first limit plate is slidably connected to the first slide rail and connected to the first sleeve; the first motor is arranged on the mounting seat, and the first motor is configured to drive the first screw to rotate via the first transmission member to drive the first sleeve to move along the first screw, and the first limit plate moves toward or away from the clamping assembly driven by the first sleeve.

[0011] A simple screw drive module is provided. A first motor drives the rotation of a first screw, which in turn drives a first screw sleeve to slide along a first slide rail, ultimately driving a first stop plate to move toward or away from a clamping assembly. In the event of an emergency stop during transport, the first stop plate is pushed by the inertia of the material, but the first screw sleeve, which is threaded onto the first screw, is not pressed to move along the first screw, ultimately ensuring that the first and second stop plates maintain a firm grip on the material.

[0012] In some embodiments, the first transmission member includes a first driving wheel, a first driven wheel and a first synchronous belt, wherein the first driving wheel is installed on the driving end of the first motor, the first driven wheel is installed on the end of the first screw rod, and the first synchronous belt is sleeved on the first driving wheel and the first driven wheel.

[0013] By configuring the first transmission member to include a first driving wheel, a first driven wheel, and a first synchronous belt, the first motor can be positioned above or below the first screw, thereby shortening the length of the conveying mechanism in the first direction and making the conveying mechanism more compact. When the first motor drives the first driving wheel to rotate, the first driving wheel drives the first driven wheel and the first screw to rotate synchronously via the first synchronous belt.

[0014] In some embodiments, the cylinder drive module includes a second slide rail, a cylinder and a slider, wherein: the second slide rail is arranged on the mounting seat along the first direction; the slider is slidably connected to the second slide rail and is connected to the second limit plate; the cylinder is arranged on the mounting seat, and the telescopic rod of the cylinder is connected to the slider, and the cylinder is used to drive the slider to slide along the second slide rail to drive the second limit plate to move toward or away from the clamping assembly.

[0015] A cylinder drive module with a simple structure and stable driving is provided, which can drive a second limiting plate to move stably toward or away from a clamping assembly along a second slide rail.

[0016] In some embodiments, the clamping assembly includes a third slide rail, a second motor, a second screw rod, a second nut, a third nut, a first clamping member and a second clamping member, wherein: the third slide rail and the second screw rod are arranged on the mounting seat along the second direction, and the second direction is perpendicular to the first direction; the second screw rod is provided with a first thread groove and a second thread groove with opposite rotation directions, the second nut is screwed to the second screw rod via the first thread groove, and the third nut is screwed to the second screw rod via the second thread groove; the first clamping member and the second clamping member are both slidably connected to the third slide rail, wherein the first clamping member is connected to the second nut, and the second clamping member is connected to the third nut; the second motor is arranged on the mounting seat, and the second motor is configured to drive the second screw rod to rotate via the second transmission member to drive the second nut and the third nut to move in the opposite direction along the second screw rod, and the first clamping member and the second clamping member slide closer to the middle or slide apart to both sides under the drive of the second nut and the third nut.

[0017] By configuring the clamping assembly, only one drive motor (i.e., the second motor) is required to drive the first and second clamping members to slide together or apart, thereby reducing the structural complexity and cost of the clamping assembly. Furthermore, by driving the first and second clamping members through a screw module consisting of a second motor, a second screw, a second threaded sleeve, and a third threaded sleeve, the stability of the first and second clamping members on the material can be ensured, preventing the first and second clamping members from accidentally opening in the event of an emergency stop during handling, causing the material to fall.

[0018] In some embodiments, the second transmission member includes a second driving wheel, a second driven wheel and a second synchronous belt, wherein the second driving wheel is installed on the driving end of the second motor, the second driven wheel is installed on the end of the second screw rod, and the second synchronous belt is sleeved on the second driving wheel and the second driven wheel.

[0019] By configuring the second transmission member to include a second driving wheel, a second driven wheel, and a second synchronous belt, the second motor can be positioned above or below the second lead screw, thereby shortening the width of the conveying mechanism in the second direction and making the conveying mechanism more compact. When the second motor drives the second driving wheel to rotate, the second driving wheel drives the second driven wheel and the second lead screw to rotate synchronously via the second synchronous belt.

[0020] In some embodiments, the second clamping member has the same structure as the first clamping member. The first clamping member includes a plurality of clamping jaws spaced apart along the first direction. A buffer block is provided on the inner side of the clamping jaw, and a limit block is provided at the lower end of the clamping jaw.

[0021] By configuring the first and second clamping members to include multiple jaws spaced apart along the first direction, they ensure stable gripping of the material from both sides. Buffer blocks are provided on the inner sides of the jaws to prevent damage to the material. Limit blocks are provided at the lower ends of the jaws to support and limit the material, preventing it from falling.

[0022] The present application also provides a transfer device, which includes a base, a first transfer mechanism, a rotation mechanism, and a second transfer mechanism, wherein the first transfer mechanism and the second transfer mechanism are both the transfer mechanisms described in any one of the above items;

[0023] The mounting base of the first transport mechanism is fixedly connected to the base;

[0024] The rotating mechanism is arranged on the base, the mounting base of the second transport mechanism is connected to the movable component of the rotating mechanism, and the rotating mechanism is used to drive the second transport mechanism to rotate and switch between the first position and the second position;

[0025] When the second conveying mechanism rotates to the first position, the second conveying mechanism and the first conveying mechanism are arranged in a collinear manner; when the second conveying mechanism rotates to the second position, the second conveying mechanism and the first conveying mechanism are arranged in parallel.

[0026] Through the cooperation of the first and second conveying mechanisms, the transfer device can achieve the synchronous conveying of two materials. During the conveying process, the second conveying mechanism is located in the first position, that is, the second conveying mechanism and the first conveying mechanism are arranged in a colinear manner. By adjusting the orientation of the first and second conveying mechanisms, the first limit plates of the first and second conveying mechanisms are positioned in front of the materials they are respectively conveying, thereby ensuring that both materials can be stably clamped during an emergency stop. When the two materials are conveyed into place, the second conveying mechanism can be controlled to rotate to the second position to adjust the relative position of the two materials.

[0027] In some embodiments, the rotating mechanism includes a driving member and a rotating arm, wherein: the driving member is installed on the base, the rotating arm is rotatably connected to the base and connected to the driving end of the driving member, the mounting base of the second conveying mechanism is connected to the rotating arm, and the driving member drives the rotating arm to rotate to drive the second conveying mechanism to rotate.

[0028] The second transport mechanism is connected to the driving member of the driving member via the rotating arm, ensuring that when the driving member drives the second transport mechanism to rotate, the second transport mechanism has a large enough rotation space to prevent the second transport mechanism from contacting and interfering with the first transport mechanism.

[0029] In some embodiments, the transfer device further includes a moving mechanism, the base is connected to a driving end of the moving mechanism, and the moving mechanism is used to drive the base to move in a horizontal direction and / or a vertical direction.

[0030] By providing the moving mechanism, the positions of the first conveying mechanism and the second conveying mechanism are adjusted, so that the first conveying mechanism and the second conveying mechanism can carry out the material conveying synchronously. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0045] like Figure 1 As shown, the transport mechanism in the embodiment of the present application includes a mounting base 1, a clamping assembly 2, a first limit plate 3, a second limit plate 4, a screw drive module 5 and a cylinder drive module 6, wherein:

[0046] The clamping assembly 2 is arranged on the mounting seat 1 .

[0047] The first limit plate 3 is slidably connected to the mounting base 1 and is located on the first side of the clamping assembly 2. The first limit plate 3 is transmission-connected to the screw drive module 5 provided on the mounting base 1. The screw drive module 5 is used to drive the first limit plate 3 to move toward or away from the clamping assembly 2 along a first direction (such as the X direction).

[0048] The second limit plate 4 is slidably connected to the mounting base 1 and is located on the second side of the clamping assembly 2. The second limit plate 4 is transmission-connected to the cylinder drive module 6 provided on the mounting base 1. The cylinder drive module 6 is used to drive the second limit plate 4 to move toward or away from the clamping assembly 2 along the first direction.

[0049] In the conveying mechanism provided in this embodiment of the present application, a first stopper plate 3 located on one side of the clamping assembly 2 is driven by a screw drive module 5. During material conveying, the first stopper plate 3 can be positioned in front of the material by adjusting the orientation of the conveying mechanism. For example, if the conveying mechanism needs to convey the material to the right, the orientation of the conveying mechanism can be adjusted so that the first stopper plate 3 is positioned to the right of the material.

[0050] In this way, when the conveying mechanism suddenly stops during the conveying process, the first limit plate 3 bears the inertial resistance of the material. Since the first limit plate 3 is driven by the screw drive module 5, the screw drive module 5 will not retract after being compressed, thereby preventing the material from loosening and falling.

[0051] The transport mechanism in the embodiment of the present application is suitable for transporting rectangular materials such as battery cell modules. Furthermore, to increase the carrying capacity, the transport mechanism needs to minimize its own weight. A screw drive module of the same specification weighs more than a cylinder drive module. Therefore, by configuring only the drive element of the first limit plate 3 as a screw drive module, the transport mechanism's own weight can be kept within the required range, thus avoiding affecting the carrying capacity of the transport mechanism.

[0052] like Figure 2 As shown, optionally, the screw drive module 5 includes a first slide rail 51, a first transmission member 52, a first motor 53, a first screw rod 54 and a first screw sleeve 55, wherein: the first slide rail 51 and the first screw rod 54 are arranged on the mounting base 1 along a first direction, the first screw sleeve 55 is screwed onto the first screw rod 54, and the first limit plate 3 is slidably connected to the first slide rail 51 and connected to the first screw sleeve 55. The first motor 53 is arranged on the mounting base 1, and the first motor 53 is configured to drive the first screw rod 54 to rotate via the first transmission member 52 to drive the first screw sleeve 55 to move along the first screw rod 54, and the first limit plate 3 moves toward or away from the clamping assembly 2 under the drive of the first screw sleeve 55.

[0053] When the conveying mechanism comes to an emergency stop during the conveying process, although the first limit plate 3 is pushed by the inertia of the material, the first screw sleeve 55 screwed on the first screw rod 54 will not move along the first screw rod 54 due to pressure, so that the first limit plate 3 stops suddenly at the same time, and finally ensures that the first limit plate 3 and the second limit plate 4 keep clamping the material.

[0054] Optionally, the first transmission member 52 includes a first driving wheel, a first driven wheel, and a first synchronous belt, wherein the first driving wheel is mounted on the driving end of the first motor, the first driven wheel is mounted on the end of the first screw, and the first synchronous belt is sleeved on the first driving wheel and the first driven wheel. By configuring the first transmission member 52 to include the first driving wheel, the first driven wheel, and the first synchronous belt, the first motor 53 can be arranged above or below the first screw 54, thereby shortening the length of the conveying mechanism in the first direction and making the structure of the conveying mechanism more compact. When the first motor 53 drives the first driving wheel to rotate, the first driving wheel drives the first driven wheel and the first screw to rotate synchronously via the first synchronous belt.

[0055] like Figure 2 As shown, the cylinder drive module 6 optionally includes a second slide rail 61, a cylinder 63, and a slider 62. The second slide rail 61 is disposed on the mounting base 1 along a first direction. The slider 62 is slidably connected to the second slide rail 61 and is connected to the second limit plate 4. The cylinder 63 is disposed on the mounting base 1, and the telescopic rod of the cylinder 63 is connected to the slider 62. The cylinder 63 is used to drive the slider 62 to slide along the second slide rail 61, thereby moving the second limit plate 4 toward or away from the clamping assembly 2.

[0056] like Figure 3 As shown, optionally, the clamping assembly 2 includes a third slide rail 21, a second motor 22, a second screw rod 23, a second screw sleeve 24, a third screw sleeve 25, a first clamping member 26 and a second clamping member 27, wherein: the third slide rail 21 and the second screw rod 23 are arranged on the mounting base 1 along a second direction (such as the Y direction), and the second direction is perpendicular to the first direction.

[0057] The second screw rod 23 is provided with a first thread groove and a second thread groove with opposite rotation directions. For example, the first thread groove rotates clockwise and the second thread groove rotates counterclockwise. The second screw sleeve 24 is screwed to the second screw rod 23 via the first thread groove, and the third screw sleeve 25 is screwed to the second screw rod 23 via the second thread groove. The first clamping member 26 and the second clamping member 27 are both slidably connected to the third slide rail 21, wherein the first clamping member 26 is connected to the second screw sleeve 24, and the second clamping member 27 is connected to the third screw sleeve 25.

[0058] The second motor 22 is arranged on the mounting base 1, and the second motor 22 is configured to drive the second screw rod 23 to rotate through the second transmission member 28 to drive the second screw sleeve 24 and the third screw sleeve 25 to move in the opposite direction along the second screw rod 23. The first clamping member 26 and the second clamping member 27 are driven by the second screw sleeve 24 and the third screw sleeve 25 to slide towards the middle or slide to both sides and separate.

[0059] By configuring the clamping assembly 2, it is achieved that only one drive motor (i.e., the second motor 22) is required to drive the first clamping member 26 and the second clamping member 27 to slide together toward the center or to slide apart to the sides, thereby reducing the structural complexity and cost of the clamping assembly 2. In addition, by driving the first clamping member 26 and the second clamping member 27 through the screw module composed of the second motor 22, the second screw rod 23, the second screw sleeve 24 and the third screw sleeve 25, the stability of the clamping of the material by the first clamping member 26 and the second clamping member 27 can be ensured, and the first clamping member 26 and the second clamping member 27 are prevented from accidentally opening when an emergency stop occurs during transportation, causing the material to fall.

[0060] Optionally, the second transmission member 28 includes a second driving wheel, a second driven wheel, and a second synchronous belt, wherein the second driving wheel is mounted on the drive end of the second motor 22, the second driven wheel is mounted on the end of the second screw rod 23, and the second synchronous belt is sleeved on the second driving wheel and the second driven wheel. By configuring the second transmission member 28 to include the second driving wheel, the second driven wheel, and the second synchronous belt, the second motor 22 can be positioned above or below the second screw rod 23, thereby shortening the width dimension of the conveying mechanism in the second direction and making the structure of the conveying mechanism more compact. When the second motor 22 drives the second driving wheel to rotate, the second driving wheel drives the second driven wheel and the second screw rod 23 to rotate synchronously via the second synchronous belt.

[0061] like Figure 1 and Figure 3 As shown, optionally, the second clamping member 27 has the same structure as the first clamping member 26. Taking the first clamping member 26 as an example, it includes a plurality of clamping jaws 261 arranged at intervals along the first direction, a buffer block 262 is provided on the inner side surface of the clamping jaw 261, and a limiting block 263 is provided at the lower end of the clamping jaw 261.

[0062] By configuring the first and second clamping members 26 and 27 to include a plurality of jaws 261 spaced apart along the first direction, the first and second clamping members 26 and 27 can stably clamp the material from both sides. The provision of buffer blocks 262 on the inner sides of the jaws 261 ensures flexible grip of the material, preventing damage. Furthermore, the provision of limit blocks 263 at the lower ends of the jaws 261 supports and limits the material, preventing it from falling.

[0063] Based on the same application concept, this application also provides a transfer device. Figure 4 and Figure 5 As shown, the transfer device in the embodiment of the present application includes a base 10, a first conveying mechanism 20, a rotating mechanism 30 and a second conveying mechanism 40. The first conveying mechanism 20 and the second conveying mechanism 40 are both conveying mechanisms provided by any of the above-mentioned embodiments, wherein: the mounting base 1 of the first conveying mechanism 20 is fixedly connected to the base 10.

[0064] The rotating mechanism 30 is disposed on the base 10 , and the mounting base 1 of the second transport mechanism 40 is connected to a movable component of the rotating mechanism 30 . The rotating mechanism 30 is used to drive the second transport mechanism 20 to rotate and switch between the first position and the second position.

[0065] The optional working process of the transfer device in the embodiment of the present application is as follows:

[0066] like Figure 4 As shown, the second transport mechanism 40 is controlled to rotate to the first position, so that the second transport mechanism 40 and the first transport mechanism 20 are arranged in a colinear manner.

[0067] Subsequently, the first conveying mechanism 20 and the second conveying mechanism 40 are controlled to synchronously clamp the two collinearly placed materials. Next, the orientations of the first conveying mechanism 20 and the second conveying mechanism 40 are adjusted so that the first limiting plates 3 of the first conveying mechanism 20 and the second conveying mechanism 40 are both located in front of the materials they are clamping.

[0068] Control the first conveying mechanism 20 and the second conveying mechanism 40 to convey the two clamped materials forward to the target position. Since the first limit plates 3 of the first conveying mechanism 20 and the second conveying mechanism 40 are both in front of the materials they are conveying, it is ensured that both materials can be stably clamped by the corresponding first limit plates 3 and second limit plates 4 during emergency stop, preventing the materials from falling during the conveying process.

[0069] like Figure 5 As shown, when the two materials are transported to the right position, the second transport mechanism 40 can be controlled to rotate to the second position so that the second transport mechanism 40 and the first transport mechanism 20 are arranged side by side, thereby adjusting the two materials to be placed side by side.

[0070] Finally, the first conveying mechanism 20 and the second conveying mechanism 40 are controlled to place the two materials adjusted to be parallel to each other at the target position.

[0071] It can be seen that through the mutual cooperation of the first conveying mechanism 20 and the second conveying mechanism 40, the transfer device in the embodiment of the present application realizes the synchronous conveying of two materials, and can adjust the relative positions of the two materials during the conveying process, adjusting the two collinearly placed materials to be placed side by side.

[0072] Of course, the transfer device of the embodiment of the present application can also be used to transport two materials placed side by side to a target location and then adjust the two materials to be placed collinearly. In this case, it is necessary to first control the second transport mechanism 40 to rotate to the second position so that the second transport mechanism 40 is arranged side by side with the first transport mechanism 20. Before controlling the first transport mechanism 20 and the second transport mechanism 40 to place the two picked-up materials at the target location, the two transport mechanisms 40 are first controlled to rotate to the first position so that the second transport mechanism 40 is arranged collinearly with the first transport mechanism 20.

[0073] like Figure 4 and Figure 5 As shown, optionally, the rotating mechanism 30 includes a driving member 31 and a rotating arm 32, wherein: the driving member 31 is installed on the base 10, the rotating arm 32 is rotatably connected to the base 10 and is connected to the driving end of the driving member 31, the mounting base 1 of the second conveying mechanism 40 is connected to the rotating arm 32, and the driving member 31 drives the rotating arm 32 to rotate to drive the second conveying mechanism 40 to rotate.

[0074] Since the second transport mechanism 40 is connected to the driving member of the driving member 31 via the rotating arm 32, the second transport mechanism 40 has a large enough rotation space when the driving member 31 drives the second transport mechanism 40 to rotate, thereby preventing the second transport mechanism 40 from contacting and interfering with the first transport mechanism 20.

[0075] Optionally, the transfer device in the embodiment of the present application also includes a moving mechanism, and the base 10 is connected to the driving end of the moving mechanism. The moving mechanism is used to drive the base 10 to move in the horizontal direction and / or vertical direction, thereby driving the first conveying mechanism 20 and the second conveying mechanism 40 to move synchronously to implement the conveying of materials.

[0076] The moving mechanism may adopt various existing driving devices capable of driving the first transport mechanism 20 and the second transport mechanism 40 to move, such as a robot arm.

[0077] The above description of the present application is sufficiently detailed and has certain particularities. Those skilled in the art should understand that the descriptions in the embodiments are merely exemplary, and that all changes made without departing from the true spirit and scope of the present application should fall within the scope of protection of the present application. The scope of protection claimed in the present application is defined by the claims, not by the above description in the embodiments. Furthermore, the embodiments mentioned in the present application are not limited to being implemented individually, and some embodiments can also be implemented in combination.
