Description

Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to a pallet positioning device and pallet circulation equipment. Background Art

[0002] During the production process of battery cells, the formed trays loaded with battery cells need to be transferred via a logistics line to an OCV (Open Circuit Voltage) test device for testing. Specifically, during the process of transferring pallets and battery cells along the logistics line, a photoelectric sensor is usually used to detect the position of the pallet. The start and stop of the logistics line are controlled based on the detection results of the photoelectric sensor, and the pallet and battery cells are then transferred to a preset position so that the robot arm in the OCV test device can grab the battery cells on the pallet at the preset position and carry out subsequent testing processes.

[0003] In actual applications, relying solely on photoelectric sensor detection results to control the start and stop of logistics lines can easily lead to the problem of pallets shifting relative to the preset position.

[0045] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved more clear, the technical solutions of the present invention are further explained below with reference to the accompanying drawings and through specific implementation methods.

[0046] In the description of this utility model, unless otherwise specified or limited, the terms "connected," "connect," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0047] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0048] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are used to refer to positions or locations based on the positions or locations shown in the accompanying drawings. These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0049] In the process of transferring pallets and battery cells on the logistics line, photoelectric sensors are usually used to detect the position of the pallet, and the start and stop of the logistics line are controlled according to the detection results of the photoelectric sensors, and then the pallet and battery cells are transferred to the preset position, so that the robot in the OCV testing equipment can grab the battery cells on the pallet at the preset position and carry out subsequent inspection processes. In actual application scenarios, relying solely on the detection results of the photoelectric sensor to control the start and stop of the logistics line is prone to the problem of the pallet being offset relative to the preset position. As a result, the robot in the subsequent OCV testing equipment cannot grab the battery cells at the preset position, resulting in a grabbing failure. The staff needs to reposition the battery cells, which reduces work efficiency.

[0050] In order to solve the above problems, Figures 1 to 3As shown, this embodiment provides a pallet positioning device. The pallet positioning device includes a first alignment mechanism, a second alignment mechanism, and a lifting mechanism (not shown). The first alignment mechanism is configured to align the pallet along a first direction; the second alignment mechanism is configured to align the pallet along a second direction; and the lifting mechanism is configured to lift the pallet vertically after aligning the pallet along the first and second directions. The first and second directions are perpendicular to each other in a horizontal plane.

[0051] The pallet positioning device corrects the pallet on the logistics line relative to the preset position along a first direction by setting a first correcting mechanism, and corrects the pallet on the logistics line along a second direction relative to the preset position by setting a second correcting mechanism, so that the first direction and the second direction are perpendicular to each other in the horizontal plane, thereby realizing horizontal correction and positioning of the pallet relative to the preset position on the logistics line. By setting a lifting mechanism to lift the pallet that has been horizontally corrected in a vertical direction relative to the preset position, vertical correction and positioning of the pallet on the logistics line relative to the preset position can be realized, thereby ensuring that each pallet on the material line can be corrected and positioned at the preset position with high positioning accuracy, which is convenient for subsequent processing and transportation.

[0052] Specifically, if Figures 1 to 3 As shown, the pallet positioning device provided in this embodiment also includes a frame 400, wherein the logistics belt passes through the frame 400, the first correcting mechanism and the second correcting mechanism are respectively arranged at the upper end of the frame 400 in the vertical direction, and the lifting mechanism is arranged at the lower end of the frame 400 in the vertical direction, so that the first correcting mechanism, the second correcting mechanism and the lifting mechanism can correct and position the pallet on the logistics belt without interfering with the frame 400 and the logistics belt.

[0053] As an optional solution, the first alignment mechanism includes a first alignment component 100 and a first stop component 300, wherein the first alignment component 100 and the first stop component 300 are both disposed on the frame 400, and the first alignment component 100 and the first stop component 300 are respectively disposed at both ends of the preset position along the first direction. The first alignment component 100 can drive the tray to move in the first direction, and the first stop component 300 and the first alignment component 100 jointly complete the alignment of the tray in the first direction. By respectively disposing the first alignment component 100 and the first stop component 300 at both ends of the frame 400 relative to the preset position along the first direction, the first alignment component 100 drives the tray to move in the first direction, and combined with the first stop component 300 disposed opposite to the first alignment component 100 in the first direction, the alignment of the tray in the first direction relative to the preset position can be achieved.

[0054] Specifically, when the pallet on the logistics belt needs to be aligned and positioned relative to the preset position along the first direction, the first stop assembly 300 on the frame 400 has been pre-fixed at one end of the preset position along the first direction, and the first alignment assembly 100 drives the pallet to move along the first direction until the pallet abuts against the first stop assembly 300, thereby realizing the alignment and positioning of the pallet along the first direction by the first alignment mechanism.

[0055] In other embodiments, two first correcting assemblies 100 may be provided within the first correcting mechanism. The two first correcting assemblies 100 are respectively provided at both ends of the frame 400 relative to the preset position along the first direction. The two first correcting assemblies 100 are each capable of driving the tray to move along the first direction. The driving directions of the two first correcting assemblies 100 are opposite, and the two first correcting assemblies 100 jointly complete the correction of the tray along the first direction. By providing the first correcting assemblies 100 at both ends of the frame 400 relative to the preset position along the first direction, the correction directions of the two first correcting assemblies 100 are opposite, and the two first correcting assemblies 100 are used to drive the tray to move along the first direction, the correction and positioning effect of the tray relative to the preset position along the first direction can be further improved.

[0056] Specifically, if Figures 1 to 3 As shown, the first correction component 100 includes a first driving member 110, a first adapter member 120, a first transmission member 130 and a second adapter member 140, wherein one end of the first transmission member 130 is pivoted to the output end of the first driving member 110, and the first adapter member 120 and the second adapter member 140 are both arranged on the frame 400. Any one of the first adapter member 120 and the second adapter member 140 is pivoted to the middle part of the first transmission member 130, and the other is pivoted to the end of the first driving member 110 away from the output end. The end of the first transmission member 130 away from the first driving member 110 is in contact with the tray, and the first driving member 110 can drive the end of the first transmission member 130 away from the first driving member 110 to move along the first direction. By connecting one end of the first transmission member 130 to the output end of the first driving member 110, and fixing the first adapter member 120 and the second adapter member 140 on the frame 400 respectively, any one of the first adapter member 120 and the second adapter member 140 is pivoted to the middle of the first transmission member 130, and the other is pivoted to the end of the first driving member 110 away from the output end, so that the rotation of the first transmission member 130 on the frame 400 can not only realize the driving of the tray by the first transmission member 130 along the first direction, but also when the tray moves from the outside of the first transmission member 130 relative to the preset position to the inside of the first transmission member 130 relative to the preset position under the drive of the logistics belt along the first direction, the first transmission member 130 can rotate to allow the tray to move normally through the space, thereby preventing interference between the tray and the first transmission member 130. The structure is simple and the design is ingenious.

[0057] It should be noted that in this embodiment, the first adapter 120 is pivotally connected to the middle portion of the first transmission member 130, and the second adapter 140 is pivotally connected to the end of the first driving member 110 away from the output end. In other embodiments, the first adapter 120 may also be pivotally connected to the end of the first driving member 110 away from the output end, and the second adapter 140 may also be pivotally connected to the middle portion of the first transmission member 130, and this embodiment is not specifically limited thereto.

[0058] Furthermore, in this embodiment, the first driving member 110 is a linear cylinder. Linear cylinders offer a simple structure, quick response, stable output power, and easy assembly and disassembly. In other embodiments, the first driving member 110 may also be a linear motor or other linear drive structure, which is not specifically limited in this embodiment.

[0059] Specifically, when the tray needs to be moved from the outside of the first transmission member 130 relative to the preset position to the inside of the first transmission member 130 relative to the preset position along the first direction, the output end of the first driving member 110 switches from an extended state to a retracted state. At this time, the output end of the first driving member 110 drives the first transmission member 130 to rotate along the first adapter 120, so that the first transmission member 130 blocking the conveying path of the logistics belt along the first direction is rotated and removed, so that the tray can be moved from the outside of the first transmission member 130 relative to the preset position to the inside of the first transmission member 130 relative to the preset position along the first direction. When the tray needs to be repositioned along the first direction with the first transmission member 130 inside the preset position, the output end of the first driving member 110 switches from an extended state to a stretched state. At this time, the output end of the first driving member 110 drives the first transmission member 130 to rotate in the opposite direction along the first adapter 120, so that the first transmission member 130 located outside the conveying path of the logistics belt along the first direction is moved back to its original position and abuts against the tray to move along the first direction until the tray is completely positioned along the first direction.

[0060] It should be noted that since the first driving member 110 is linearly driven, during the rotation of the first transmission member 130, interference will occur between the output end of the first driving member 110 and the first transmission member 130. By pivoting the second adapter 140 at the end of the first driving member 110 away from the output end, the pivotal rotation between the first driving member 110 and the second adapter 140 can be utilized to provide a movable space between the output end of the first driving member 110 and the first transmission member 130, thereby solving the interference problem between the output end of the first driving member 110 and the first transmission member 130.

[0061] In an optional embodiment, the first transmission member 130 includes a first transmission part 131, a second transmission part 132 and a third transmission part 133 connected in sequence, a first rotating shaft 121 extending in a vertical direction is provided in the first adapter 120, and a second rotating shaft 141 extending in a vertical direction is provided in the second adapter 140. The first transmission part 131 is pivotally connected to the output end of the first driving member 110, the second transmission part 132 is pivotally connected to the first rotating shaft 121, and the third transmission part 133 can abut against the tray, and the end of the first driving member 110 away from the output end is rotatably connected to the second rotating shaft 141.

[0062] To further enhance protection for the first transmission member 130 and the tray, the first alignment assembly 100 further includes a first elastic buffer 150. The first elastic buffer 150 is positioned at the end of the third transmission portion 133 closest to the tray. The first elastic buffer 150 provides elastic cushioning for contact between the tray and the first transmission member 130. By positioning the first elastic buffer 150 at the end of the third transmission portion 133 closest to the tray, when the third transmission portion 133 abuts the tray under the drive of the first driver 110, the first elastic buffer 150 is sandwiched between the third transmission portion 133 and the tray, cushioning direct contact between the third transmission portion 133 and the tray, thereby enhancing protection for the first transmission member 130 and the tray. It should be noted that in this embodiment, the first elastic buffer 150 is made of rubber. Rubber materials have excellent elasticity, toughness, and wear resistance. In other embodiments, the first elastic buffer 150 may be made of other elastic materials, or may be a spring or other elastic structure, which is not specifically limited in this embodiment.

[0063] As an optional solution, the first stop assembly 300 includes a second drive member 310 and a second transmission member 320, wherein the second drive member 310 and the second transmission member 320 are both disposed on the frame 400, and the second transmission member 320 is connected to the output end of the second drive member 310. The second drive member 310 can drive the second transmission member 320 to move in the vertical direction, and the second transmission member 320 can abut against the tray. By arranging the second drive member 310 to drive the second transmission member 320 to move in the vertical direction, when the tray needs to be corrected and positioned in the first direction, the second drive member 310 drives the second transmission member 320 to move upward in the vertical direction, so that the second transmission member 320 blocks the movement path of the tray in the first direction, and cooperates with the drive of the first transmission member 130 of the first drive member 110 to achieve the correct positioning of the tray in the first direction. When the pallet needs to be transported to the subsequent workstation after being corrected and positioned, the second drive member 310 drives the second transmission member 320 to move downward in the vertical direction so that the second transmission member 320 no longer blocks the movement path of the pallet along the first direction, and the logistics belt completes the transportation of the pallet along the first direction.

[0064] It should be noted that in this embodiment, the second driving member 310 is a linear cylinder. Linear cylinders have a simple structure, are responsive, have stable output power, and are easy to assemble and disassemble. In other embodiments, the second driving member 310 may also be a linear motor or other linear drive structure, and this embodiment does not specifically limit this.

[0065] In order to further improve the protection of the second transmission member 320 and the tray, a second elastic buffer 330 is provided at one end of the second transmission member 320 close to the tray. The second elastic buffer 330 can provide a buffer for the contact between the second transmission member 320 and the tray. It should be noted that the second elastic buffer 330 is made of rubber material. The rubber material has good elasticity, toughness and wear resistance. In other embodiments, the second elastic buffer 330 can also be made of other elastic materials, or the second elastic buffer 330 can also be an elastic structure such as a spring, which is not specifically limited in this embodiment.

[0066] Combine Figures 1 to 3 The specific structure of the second correcting mechanism is described below. The second correcting mechanism includes two second correcting assemblies 200, each fixed to the frame 400 at both ends along the second direction relative to the preset position. The two second correcting assemblies 200 are each capable of driving the pallet in the second direction. The two second correcting assemblies 200 are driven in opposite directions, and together, the two second correcting assemblies 200 correct the pallet in the second direction. By disposing the second correcting assemblies 200 at both ends of the frame 400 along the second direction relative to the preset position, the two second correcting assemblies 200 are each capable of driving the pallet in the second direction, and the two second correcting assemblies 200 are driven in opposite directions, thereby achieving correcting the pallet's deviation in the second direction. This achieves a simple structure and an ingenious design.

[0067] Specifically, when the pallet on the logistics belt needs to be corrected and positioned along the second direction relative to the preset position, the two second correcting components 200 jointly drive the pallet to move along the second direction until the pallet is corrected and positioned along the second direction relative to the preset position by the two second correcting components 200.

[0068] In other embodiments, a second correcting component 200 and a second stop component may also be provided in the second correcting mechanism. The second correcting component 200 and the second stop component are respectively provided at both ends of the frame 400 relative to the preset position along the second direction. The second correcting component 200 can drive the tray to move along the second direction. The second stop component and the second correcting component 200 jointly complete the correction of the tray along the second direction.

[0069] Specifically, the second alignment component 200 includes a third drive member 210 and a third transmission member 220, wherein the third transmission member 220 is connected to the output end of the third drive member 210, and the third drive member 210 can drive the third transmission member 220 to move in the second direction, and the third transmission member 220 can abut against the tray. By providing the third transmission member 220 connected to the output end of the third drive member 210, the third transmission member 220 is driven by the third drive member 210 to move in the second direction and abut against the tray, thereby driving the tray in the second direction. It should be noted that, in this embodiment, the third drive member 210 is a linear cylinder. The linear cylinder has a simple structure, sensitive response, stable output power, and is easy to assemble and disassemble. In other embodiments, the third drive member 210 can also be a linear motor or other linear drive structure, which is not specifically limited in this embodiment.

[0070] In this embodiment, since the transport direction of the logistics belt is the first direction, the second alignment assembly 200 does not block the pallet's path during the conveyance of the pallet. Therefore, the second alignment assembly 200 does not need to include a pivoting structure identical to that of the first alignment assembly 100. In other embodiments, if the transport direction of the logistics belt is the second direction, the second alignment assembly 200 may need to include a pivoting structure identical to that of the first alignment assembly 100.

[0071] In addition, the specific structure and working principle of the second stop assembly are the same as those of the first stop assembly 300 , and will not be described again here to ensure brevity.

[0072] As an optional feature, the second alignment assembly 200 further includes a third elastic buffer 230, which is disposed at the end of the third transmission member 220 proximal to the tray. The third elastic buffer 230 provides elastic cushioning for contact between the tray and the third transmission member 220. By disposing the third elastic buffer 230 at the end of the third transmission member 220 proximal to the tray, when the third transmission member 220 abuts the tray under the drive of the third driving member 210, the third elastic buffer 230 can be sandwiched between the third transmission member 220 and the tray, cushioning direct contact between the third transmission member 220 and the tray, thereby enhancing protection for both the third transmission member 220 and the tray. It should be noted that in this embodiment, the third elastic buffer 230 is made of rubber. Rubber materials have excellent elasticity, toughness, and wear resistance. In other embodiments, the third elastic buffer 230 may be made of other elastic materials, or may be a spring or other elastic structure, which is not specifically limited in this embodiment.

[0073] In an optional embodiment, the lifting mechanism includes a fourth drive member and a fourth transmission member, wherein the fourth drive member and the fourth transmission member are both arranged in the vertical direction at the lower end of the frame 400 relative to the preset position, the fourth transmission member is connected to the output end of the fourth drive member, the fourth drive member can drive the fourth transmission member to move in the vertical direction, and the fourth drive member can abut against the pallet. By arranging the fourth drive member and the fourth transmission member at the lower end of the frame 400 relative to the preset position, the fourth drive member is used to drive the fourth transmission member to move in the vertical direction, so that the fourth transmission member abuts against the pallet and drives the pallet to lift in the vertical direction, thereby achieving the correct positioning of the pallet in the vertical direction relative to the preset position. It should be noted that in this embodiment, the fourth drive member is a linear cylinder. The linear cylinder has a simple structure, sensitive response, stable output power, and is easy to assemble and disassemble. In other embodiments, the fourth drive member can also be a linear motor or other linear drive structure, which is not specifically limited in this embodiment.

[0074] As an optional solution, a positioning protrusion is provided on the upper end surface of the fourth transmission member, and a positioning groove is provided on the lower end surface of the tray. When the fourth transmission member abuts against the tray, the positioning protrusion and the positioning groove are docked and matched to further improve the docking accuracy of the fourth transmission member and the tray.

[0075] Furthermore, at least two positioning protrusions may be spaced apart on the upper end surface of the fourth transmission member, and at least two corresponding positioning grooves may be spaced apart on the lower end surface of the tray to further enhance the docking effect between the fourth transmission member and the tray. It should be noted that in this embodiment, the tray is rectangular, and two positioning grooves are spaced apart along the diagonal of the lower end surface of the tray. The fourth transmission member is provided with two positioning protrusions corresponding to the number and position of the positioning grooves on the tray. In other embodiments, the specific position and number of the positioning protrusions and positioning grooves may be adjusted according to actual needs, and this embodiment does not impose any specific limitations.

[0076] In an optional embodiment, a fourth elastic buffer may be further provided on the upper end surface of the fourth transmission member.
