Description

Technical Field

[0001] This application relates to the field of production equipment technology, and more specifically, to a conveying device. Background Technology

[0002] In the production process, conveyor systems with conveyor rollers are frequently used to transport materials. Taking the photovoltaic industry as an example, when spraying silicon wafers, the wafers are placed face down on the conveyor rollers of the system. A motor drives the rollers, and the movement of the wafer is propelled by the friction between the roller surface and the wafer's face. Currently, the conveyor rollers are connected to the machine base at both ends via bearings, and the drive motor is connected to the rollers via gears and other transmission components. After a period of use, the friction between the roller surface and the silicon wafer causes dirt to accumulate, requiring removal and cleaning. Simultaneously, dirt accumulates on the gears and other transmission components, affecting transmission efficiency and potentially causing the rollers to vibrate. Furthermore, the confined space inside the conveyor system makes loading and unloading the rollers inconvenient, resulting in high time and labor costs for maintenance and posing certain safety risks.

The second direction is perpendicular to the first direction and perpendicular to the axial direction of the conveyor roller in the working position.

[0011] In an optional embodiment, the conveying roller is provided with a second guide groove, and the lifting drive is used to drive the lifting bracket to abut against the second guide groove in a second direction to support the conveying roller.

Detailed Implementation

[0024] In related conveying devices, the conveyor rollers are connected to the drive unit via physical transmission components (such as gears). This means that the installation and removal of these transmission components often need to be considered when disassembling and installing the conveyor rollers. Furthermore, transmission components such as gears are easily affected by contamination, which can disrupt their transmission. Due to the limited internal space of the conveying device, manual loading and unloading of the conveyor rollers is inconvenient and poses certain safety risks.

[0025] To address the shortcomings of the aforementioned technologies, this application provides a conveying device that uses magnetic force to drive the conveyor rollers, reducing the use of physical transmission components and improving the convenience of loading and unloading the conveyor rollers. Simultaneously, a replacement mechanism is provided to achieve automatic loading and unloading of the conveyor rollers, reducing labor costs and safety risks.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0030] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0031] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0032] Figure 1 This is a schematic diagram of the conveying device from a first perspective in one embodiment of this application; Figure 2 This is a schematic diagram of the conveying device in one embodiment of this application from a second perspective. Figure 1 and Figure 2 As shown, the conveying device provided in this embodiment includes a frame 100, a plurality of conveying rollers 200, a magnetic drive mechanism, and a replacement mechanism. A mounting assembly 140 is provided on the frame 100. The mounting assembly 140 is used to support the conveying rollers 200 in a working position or release the conveying rollers 200. The plurality of conveying rollers 200 in the working position are arranged parallel to each other along a first direction and can rotate relative to the frame 100. The outer circumferential surface of the conveying rollers 200 is used to carry materials. The magnetic drive mechanism is used to drive the plurality of conveying rollers 200 to rotate via magnetic force to convey materials. The replacement mechanism is used to remove the conveying rollers 200 released by the mounting assembly 140 from the working position and to move the conveying rollers 200 to the working position for support by the mounting assembly 140. Figure 1 and Figure 2 In the diagram, the first direction is indicated by arrow ab, and it is perpendicular to the axial direction of each conveying roller 200. Optionally, in the operating state, both the first direction and the axis of each conveying roller 200 are parallel to the horizontal plane. It should be understood that the working position of the conveying roller 200 refers to the position of the conveying roller 200 when it is performing its material conveying function. When maintenance is required, the conveying roller 200 needs to be removed from its working position.

[0033] In this embodiment, the frame 100 includes two end plates 120 arranged parallel to each other in a first direction, and two side plates 110 arranged parallel to each other in the axial direction of the conveying roller 200. The conveying roller 200 is disposed between the two side plates 110. The mounting assembly 140 is disposed on the two side plates 110, and the two ends of the conveying roller 200 are respectively connected to the side plates 110 through the two mounting assemblies 140.

[0034] The conveying device in this embodiment also has a buffer area, which is disposed below the working position of the conveyor roller 200 and is used to store the conveyor roller 200 unloaded from the working position. Further, the frame 100 also includes a buffer bracket 160, which is disposed in the buffer area and is used to support the conveyor roller 200 unloaded from the working position. Multiple buffer brackets 160 may be provided; each buffer bracket can support a conveyor roller 200 that is to be cleaned or maintained, or it can support a conveyor roller 200 that has been cleaned and maintained and is awaiting installation in the working position.

[0035] In this embodiment, the mounting assembly 140 is disposed on the outer side of the side plate 110. For example... Figure 1 As shown, the frame 100 may further include a baffle 130 for shielding the buffer area. Furthermore, a window may be provided on the baffle 130 for easy observation and maintenance of the buffer area, and also for facilitating the removal of the conveyor roller 200 to be cleaned and the placement of the cleaned conveyor roller 200 from the buffer area. Furthermore, a movable door (not shown in the figure) may be provided on the window of the baffle 130 to open or close the window.

[0036] Figure 3 for Figure 1 Enlarged view of section III in the middle; Figure 4 This is a schematic diagram illustrating the fit between the end of the conveyor roller 200 and the side plate 110 in one embodiment of this application. Figure 3 and Figure 4 As shown, in this embodiment, the conveying roller 200 includes a roller 220 and a roller shaft 210. The roller 220 is sleeved on the roller shaft 210 and can rotate relative to the roller shaft 210. The mounting assembly 140 is used to support the end of the roller shaft 210. The magnetic drive mechanism includes a first drive member 310, an active magnetic member 320, and a driven magnetic member 330. The driven magnetic member 330 is disposed at the end of the roller 220. The active magnetic member 320 is coupled to the driven magnetic member 330. The first drive member 310 is used to drive the active magnetic member 320 to rotate, so that the driven magnetic member 330 drives the roller 220 to rotate under the action of magnetic force. It should be understood that the rotation of the conveying roller 200 to convey materials described in this application specifically refers to the rotation of the roller 220 of the conveying roller 200, and does not require that other components in the conveying roller 200 (such as the roller shaft 210) must also rotate.

[0037] It is understandable that since the active magnetic component 320 and the driven magnetic component 330 do not directly contact each other, but transmit torque through magnetic force so that the roller 220 can rotate relative to the roller shaft 210, it is not easy to be interfered with by the transmission structure when loading and unloading the conveyor roller 200, thus facilitating the loading and unloading of the conveyor roller 200.

[0038] In this embodiment, the magnetic drive mechanism further includes a first drive shaft 340 extending along a first direction. The first drive shaft 340 is rotatably connected to the frame 100. Multiple active magnetic elements 320 are spaced apart on the first drive shaft 340 along the first direction. A first drive element 310 drives the first drive shaft 340 to rotate the multiple active magnetic elements 320. By setting the first drive shaft 340, only one first drive element 310 is needed to drive the conveyor rollers 200 in their working positions to rotate synchronously. In this embodiment, the first drive element 310 can be a motor. In this embodiment, both ends of the first drive shaft 340 are rotatably connected to two end plates 120. The first drive element 310 is located on the outside of the end plates 120, and its output shaft passes through the end plates 120 and is connected to the first drive shaft 340 via a transmission belt 350 to drive the first drive shaft 340. In other embodiments, the first drive element 310 can also be directly connected to the first drive shaft 340 (i.e., direct drive).

[0039] Specifically, in this embodiment, the end of the roller 220 is fixed to the driven magnetic member 330, which is annular and rotatably connected to the roller shaft 210 via a bearing 230. In other embodiments, the roller 220 can also be directly rotatably connected to the roller shaft 210 via the bearing 230. In this embodiment, the lower edge of the side plate 110 has a clearance notch 111, which is used to avoid the conveyor roller 200, allowing the end of the conveyor roller 200 to extend to the outside of the side plate 110 and connect to the mounting assembly 140. Figure 4 As shown, the clearance notch 111 is a downward-facing semi-circular notch, which allows the conveyor roller 200 to move downward when the mounting assembly 140 releases the conveyor roller 200.

[0040] In this embodiment, each roller 210 in the working position has two ends that cooperate with a mounting assembly 140. Roller fixing members 240 are provided at both ends of the roller 210, and the roller fixing members 240 have abutment holes 241. The mounting assembly 140 includes a mounting bracket and a second drive member 146. The mounting bracket is connected to the frame 100, and the second drive member 146 is connected to the mounting bracket. The output end of the second drive member 146 can abut into or out of the abutment hole 241 of the roller fixing member 240 along the axial direction of the roller 210.

[0041] In this embodiment, the roller shaft fixing member 240 can be fixedly connected to the end face of the roller shaft 210 by bolts. The abutment hole 241 can be a tapered hole, which has a good guiding effect, allowing the position of the roller shaft fixing member 240 to be determined after the output section of the second drive member 146 abuts into the hole. In order to better cooperate with the abutment hole 241, the output end of the second drive member 146 is provided with an abutment portion 147, which is a tapered structure adapted to the shape of the abutment hole 241. The second drive member 146 can drive the abutment portion 147 to abut into the abutment hole 241, thereby fixing the roller shaft fixing member 240, and at the same time fixing the conveyor roller 200. It can be understood that since a mounting component 140 is provided at each end of the conveyor roller 200, the mounting component 140 provides both upward support force and a certain clamping force, so that the roller shaft 210 of the conveyor roller 200 can maintain better stability.

[0042] In this embodiment, the roller fixing member 240 is provided with two abutment holes 241, and correspondingly, the output end of the second driving member 146 is provided with two abutment portions 147. In other embodiments, the number of abutment holes 241 can be increased or decreased as needed. Optionally, the type of the second driving member 146 includes, but is not limited to, a cylinder, a hydraulic cylinder, and a linear motor.

[0043] In this embodiment, the mounting bracket of the mounting assembly 140 includes a guide 141, a first connector 142, a second connector 143, and a third connector 144. The guide 141 is connected to the side plate 110. The first connector 142 and the second connector 143 are spaced apart from each other and are both connected to the guide 141. The third connector 144 is connected to the first connector 142 and the second connector 143. A second drive 146 is disposed in the space formed by the guide 141, the first connector 142, the second connector 143, and the third connector 144, and the second drive 146 is connected to the inner side of the third connector 144.

[0044] In this embodiment, a first guide groove 145 is provided on the mounting bracket. After the roller shaft fixing member 240 partially abuts against the first guide groove 145, the conveying roller 200 is in the working position. Specifically, the first guide groove 145 is provided on the lower side of the guide member 141, and the first guide groove 145 is a V-shaped groove. It can be understood that when the roller shaft fixing member 240 abuts against the first guide groove 145 from bottom to top, it can be guided by the first guide groove 145, so that the conveying roller 200 accurately reaches the working position. Correspondingly, the upper end of the roller shaft fixing member 240 can be set as a V-shaped structure adapted to the shape of the first guide groove 145.

[0045] In this embodiment, the conveying roller 200 is provided with a second guide groove 242, which can cooperate with the buffer bracket 160 to reliably support the conveying roller 200. Furthermore, in this embodiment, the second guide groove 242 can also cooperate with a replacement mechanism, allowing the replacement mechanism to engage with the second guide groove 242 during conveying the conveying roller 200, thus achieving reliable support. Specifically, the second guide groove 242 is located at the lower end of the roller fixing member 240, and can be a V-shaped groove.

[0046] Figure 5 This is a partial schematic diagram of a conveying device in one embodiment of this application. (In conjunction with...) Figure 1 and Figure 5 In this embodiment, the replacement mechanism includes a third drive member 410, a lifting drive member 420, and a lifting bracket 430. The third drive member 410 is driveably connected to the lifting drive member 420, and the lifting drive member 420 is driveably connected to the lifting bracket 430. The third drive member 410 drives the lifting drive member 420 to move in a first direction, and the lifting drive member 420 drives the lifting bracket 430 to move in a second direction. The lifting bracket 430 supports the conveyor roller 200. The second direction is perpendicular to the first direction and perpendicular to the axial direction of the conveyor roller 200 in its working position. In this embodiment, the second direction is... Figure 1 The direction indicated by the ef arrow in the diagram; when the conveying device is in use, the second direction is the vertical direction.

[0047] By providing the lifting drive 420 and the lifting bracket 430, the lifting bracket 430 can be driven to rise along the second direction to below the conveyor roller 200 in the working position, and receive the conveyor roller 200 released by the mounting assembly 140. Furthermore, after receiving the conveyor roller 200, it can move downwards along the second direction, thereby removing the conveyor roller 200 from the working position. In this embodiment, the lifting bracket 430 can be supported by the roller shaft fixing member 240, specifically by abutting against the second guide groove 242 for reliable support; correspondingly, the portion of the lifting bracket 430 used to support the conveyor roller 200 is provided with a V-shaped structure adapted to the second guide groove 242.

[0048] By setting the third driving component 410, the conveying roller 200 can be conveyed in the first direction. For example, the buffer area is provided with multiple buffer supports 160, which are arranged at intervals in the first direction. The third driving component 410 can move the conveying roller 200 along the first direction to an empty buffer support 160 for storage; and the conveying roller 200 can also be picked up from any buffer support 160 and transported along the first direction to directly below the working position where the conveying roller 200 needs to be installed. Then, the lifting driving component 420 is used to lift the conveying roller 200 to be installed to the working position.

[0049] Optionally, in this embodiment, the lifting bracket 430 and the buffer bracket 160 are misaligned in the axial direction of the conveying roller 200, that is, the projection of the lifting bracket 430 along the second direction does not fall on the buffer bracket 160. When the conveying roller 200 is placed on the buffer bracket 160, the buffer bracket 160 is only supported by a portion of the roller shaft fixing member 240, and the other portion of the roller shaft 210 support member extends beyond the buffer bracket 160 along the axial direction of the conveying roller 200, so that this extended portion can be supported by the lifting bracket 430. In this embodiment, the type of the lifting drive member 420 includes, but is not limited to, a cylinder, a hydraulic cylinder, and a linear motor.

[0050] In this embodiment, the replacement mechanism includes two lifting drive members 420 and two lifting brackets 430. The two lifting drive members 420 are located on both sides of the frame 100 along the axial direction of the conveyor roller 200. Each of the two lifting drive members 420 is driveably connected to a lifting bracket 430, and the two lifting brackets 430 support both ends of the conveyor roller 200. The replacement mechanism also includes a second drive shaft 440 extending along the axial direction of the conveyor roller 200. Both ends of the second drive shaft 440 are driveably connected to the two lifting drive members 420 via a drive member 450. A third drive member 410 drives the second drive shaft 440 to rotate, thereby causing the two lifting drive members 420 to move synchronously in a first direction. By providing the second drive shaft 440, the synchronous movement of the two lifting drive members 420 can be achieved using only one third drive member 410, allowing the two lifting drive members 420 to better cooperate in supporting the conveyor roller 200. In this embodiment, the transmission component 450 is a transmission belt; in other embodiments, the transmission component 450 may also be a chain. Optionally, the third drive component 410 is a stepper motor.

[0051] Furthermore, the frame 100 also includes a guide rail 150 extending along a first direction, and the lifting drive 420 slidingly engages with the guide rail 150. By setting the guide rail 150, the movement path of the lifting drive 420 can be limited, thereby improving the reliability of the lifting drive 420 during movement.

[0052] When it is necessary to replace the conveyor roller 200, the conveying device can be controlled in the following manner:

[0053] First, stop the operation of the magnetic drive mechanism. Control the third drive component 410 to drive the lifting drive component 420 to move below the conveyor roller 200 that needs to be replaced. Then, the lifting drive component 420 drives the lifting bracket 430 to move upward and support it on the roller shaft fixing component 240. The second drive component 146 of the mounting assembly 140 disengages the abutment part 147 from the abutment hole 241 of the roller shaft fixing component 240. At this time, the conveyor roller 200 is released by the mounting assembly 140 and supported on the lifting bracket 430. Afterward, the lifting drive component 420 drives the conveyor roller 200 to descend. The third drive component 410 drives the lifting drive component 420, the lifting bracket 430, and the conveyor roller 200 to move laterally above the idle buffer bracket 160. Then, the lifting drive component 420 lowers the conveyor roller 200 onto the buffer bracket 160. Afterwards, the operator can remove the conveyor roller 200 from the buffer bracket 160 for maintenance and cleaning, and then return the maintained conveyor roller 200 to the buffer bracket 160. When it is necessary to install the conveyor roller 200, firstly, the third drive component 410 drives the lifting bracket 430 to move to the buffer bracket 160 where the conveyor roller 200 to be installed is located. Then, the lifting drive component 420 drives the lifting bracket 430 to lift the conveyor roller 200. Then, the third drive component 410 drives the lifting bracket 430 and the conveyor roller 200 to move below the working position of the conveyor roller 200 to be installed. The lifting drive component 420 lifts the conveyor roller 200 to the working position. Then, the second drive component 146 of the installation component 140 abuts the abutment part 147 into the abutment hole 241 of the roller fixing component 240, completing the installation of the conveyor roller 200. It can be seen that the entire process of disassembling and installing the conveyor roller 200 is completed by the conveying device, saving manpower and reducing operational risks.

[0054] Optionally, a sensor can be installed on the buffer bracket 160 to determine whether a conveyor roller 200 is stored there. When the buffer area is full of conveyor rollers 200, a prompt message can be issued to remind the operator. Furthermore, the buffer area can be divided into a pending buffer area and a pending installation buffer area; the pending buffer area is used to store conveyor rollers 200 that have been unloaded from the work position and are waiting for cleaning and maintenance, while the pending installation buffer area is used to store conveyor rollers 200 that have been maintained and are waiting for installation.

[0055] The conveying device of this application can be used to convey various materials, especially sheet and plate materials, including but not limited to silicon wafers and solar cells used to make photovoltaic modules.

[0056] In summary, this application provides a conveying device, including a frame 100, a plurality of conveying rollers 200, a magnetic drive mechanism, and a replacement mechanism. An installation assembly 140 is mounted on the frame 100. The installation assembly 140 supports the conveying rollers 200 in a working position or releases the conveying rollers 200. The plurality of conveying rollers 200 in the working position are arranged parallel to each other along a first direction and can rotate relative to the frame 100.
