Description

Technical Field

[0001] This utility model relates to a conveying device, and more particularly to a workpiece transfer mechanism. Background Technology

[0002] In the lithium battery production process, the transfer and handover of electrode packs is a critical step. With the continuous development of lithium battery production technology and increasingly stringent production process requirements, the current method of gripping electrode packs typically uses a single-sided gripper arm to grasp or release them. However, this method suffers from poor stability in gripping the electrode packs, making it difficult to precisely control the opening and closing position and force of the gripper arm. Therefore, a more efficient and precise electrode pack handover mechanism is urgently needed. Utility Model Content

[0003] The purpose of this utility model is to provide a workpiece transfer mechanism to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this utility model is:

[0005] A workpiece transfer mechanism includes: a base plate; a gripper unit disposed on the base plate, the gripper unit having a rotatable transmission component, a first clamping block and a second clamping block pulsatingly disposed with the transmission component, the transmission component rotating to drive the first clamping block and the second clamping block to move closer or further apart, and multiple grippers arranged in a circumferential array on the base plate; and a transmission cam rotatable relative to the base plate, the transmission cam rotating relative to the base plate to drive multiple transmission components to reciprocate.

[0006] This technical solution has at least the following beneficial effects: Multiple gripper units are provided on the base plate for clamping or lowering the electrode assembly. In use, the base plate can be fixed while the drive cam rotates relative to the base plate, allowing the external workstation to move around the multiple gripper units on the base plate to transfer the electrode assembly between different workstations. Alternatively, the base plate can be rotated while the drive cam is fixed, allowing the drive cam to rotate relative to the base plate. In this case, the base plate drives the multiple gripper units to move, directly transferring the electrode assembly between different workstations. Regardless of the method, when the drive cam is relative to the base plate... When rotating, it can drive the transmission component to rotate, and the transmission component can drive the first clamping block and the second clamping block to move closer or further apart. A space for picking up and placing the pole set is formed between the first clamping block and the second clamping block. When the first clamping block and the second clamping block move closer or further apart, the pole set can be clamped. When the first clamping block and the second clamping block move closer or further apart, the pole set can be released. In this way, the pole set can be picked up and placed by driving the first clamping block and the second clamping block to move closer or further apart. This helps to ensure that the force is evenly applied on both sides when the pole set is clamped, better control the clamping force of the pole set, improve the stability of the pole set clamping, and thus achieve efficient and accurate transfer and handover of the pole set.

[0007] As a further improvement to the above technical solution, the gripper unit includes a mounting base, a first slide, and a second slide. The mounting base is connected to the base plate. The first slide and the second slide are slidably connected to the mounting base. The middle part of the transmission member is rotatably connected to the first slide, and the two ends of the transmission member are respectively drivenly connected to the first slide and the second slide. The first clamping block is connected to the first slide, and the second clamping block is connected to the second slide. The mounting base, connected to the base plate, provides mounting fulcrums for the first and second slides. At this time, the first and second slides are slidably connected to the mounting base. When the transmission cam rotates to drive the transmission member to rotate, the two ends of the transmission member provide power to the first and second slides respectively, causing the first and second slides to slide closer to or further away from each other on the mounting base. This can smoothly drive the first and second clamping blocks to move closer to each other to clamp the electrode group or move further away to release the electrode group, further improving the stability of picking up and placing the electrode group.

[0008] As a further improvement to the above technical solution, a spring is connected between the first slide and the second slide. When the first slide and the second slide move away from each other, that is, when the first clamp and the second clamp release the pole group, the spring is elastically stretched. When the external force that causes the first slide and the second slide to move away from each other is removed, the spring elastically returns to its original state, pulling the first clamp and the second clamp closer together, thereby clamping the pole group together.

[0009] As a further improvement to the above technical solution, the two ends of the transmission component are respectively provided with a first limiting groove and a second limiting groove. The first slide is connected to a first limiting wheel, which is located in the first limiting groove. The second slide is connected to a second limiting wheel, which is located in the second limiting groove. When the transmission component rotates, it provides power to the first limiting wheel on the first slide and the second limiting wheel on the second slide through its two ends. At this time, the first limiting groove and the second limiting groove can respectively provide space for limiting and moving away from the first limiting wheel and the second limiting wheel. As the transmission component rotates, the first limiting wheel will slide relative to the first limiting groove, and the second limiting wheel will slide relative to the second limiting groove. The horizontal offset of the first limiting wheel and the second limiting wheel caused by the rotation of the transmission component can respectively drive the first slide and the second slide to move closer or further away from each other, thereby converting the power of the transmission component rotation into the power to drive the first slide and the second slide to slide.

[0010] As a further improvement to the above technical solution, the transmission component is connected to a transmission wheel, and a transmission part is formed on the outer side of the transmission cam. The transmission part is located on both sides of the base plate in the rotation direction and guide inclined surfaces are formed respectively. The two guide inclined surfaces are inclined from top to bottom in a direction that approaches each other. When the base plate rotates, the transmission wheel can abut against the guide inclined surfaces. When the transmission cam rotates relative to the base plate, the transmission part on the outer side of the transmission cam passes through the gripper unit. Since the transmission part is located on both sides of the base plate in the direction of rotation, guide slopes are provided. Regardless of whether the transmission cam rotates forward or backward relative to the base plate, when the guide slope on the transmission part abuts against the transmission wheel on the transmission component, the transmission component abuts against the transmission wheel through its guide slope. Due to the inclined setting of the guide slope, as the transmission component rotates, the pressure of the guide slope on the transmission wheel gradually increases, and drives the transmission component to rotate through the transmission wheel. When the transmission component drives the transmission wheel to move along the guide slope to the bottom of the transmission component, the transmission wheel can pass over the bottom of the transmission component and abut against the guide slope on the other side. At this time, it can assist the transmission component to rotate in the opposite direction, thus stably driving the first slide and the second slide to move closer or further apart.

[0011] As a further improvement to the above technical solution, multiple transmission units are arranged around the rotation axis of the base plate. When the transmission cam rotates relative to the base plate, the multiple transmission units on its outer side can respectively drive the gripper unit, thereby enabling multiple gripper units to simultaneously pick up and place pole groups, better meeting the needs of production and use.

[0012] As a further improvement to the above technical solution, this utility model also includes a mandrel, the top of which passes through the base plate and is synchronously connected to the base plate. The transmission cam is rotatably connected to the top of the mandrel. Since the mandrel and base plate are synchronously connected, external power can drive the base plate to rotate via the mandrel. The transmission cam is rotatably connected to the end of the mandrel that extends through the base plate. At this point, the transmission cam can be positioned using an external structure, resulting in a configuration where the base plate rotates while the transmission cam remains stationary, thus achieving rotation of the transmission cam relative to the base plate.

[0013] As a further improvement to the above technical solution, this utility model also includes a bushing, which is connected to the outside of the mandrel. The bushing can be connected to an external structural component, in which case the mandrel is located inside the bushing and can rotate relative to the bushing, thus assisting in positioning the mandrel and improving the stability of the mandrel's rotation.

[0014] As a further improvement to the above technical solution, a transmission gear is connected to the bottom end of the mandrel. External power can drive the mandrel to rotate by meshing with the transmission gear, thereby improving the stability and controllability of the mandrel driving the base plate to rotate.

[0015] As a further improvement to the above technical solution, the transmission cam is provided with a fixing hole. External screws, bolts, or other connecting parts can be driven into the fixing hole to fix the transmission cam to the external structural components, thereby facilitating the positioning of the transmission cam.

[0026] Reference Figure 1 and Figure 3A workpiece transfer mechanism includes a base plate 100, a gripper unit, and a transmission cam 300. The gripper unit is disposed on the base plate 100 and has a rotatable transmission member 210, a first clamping block 220, and a second clamping block 230 that are pulsatingly connected to the transmission member 210. When the transmission member 210 rotates, it can drive the first clamping block 220 and the second clamping block 230 to move closer or further apart. Multiple gripper units are arranged in a circumferential array on the base plate 100. The transmission cam 300 can rotate relative to the base plate 100. The transmission cam 300 can be directly rotatably connected to the base plate 100, or the transmission cam 300 and the base plate 100 can be connected and supported by external structural members, thereby forming a structure in which the transmission cam 300 can rotate relative to the base plate 100. When the transmission cam 300 rotates relative to the base plate 100, it can drive multiple transmission members 210 to reciprocate.

[0027] As described above, the base plate 100 is equipped with multiple gripper units for clamping or lowering the electrode assembly. In use, the base plate 100 can be fixed while the transmission cam 300 rotates relative to the base plate 100. In this case, the external workstation needs to move around the multiple gripper units on the base plate 100 to transfer the electrode assembly between different workstations. Alternatively, the base plate 100 can be rotated while the transmission cam 300 is fixed, allowing the transmission cam 300 to rotate relative to the base plate 100. In this case, the base plate 100 drives the multiple gripper units to move, directly transferring the electrode assembly between different workstations. Regardless of the method, when the transmission cam 300 rotates relative to the base plate 100… The transmission component 210 can be driven to rotate, and the transmission component 210 can drive the first clamping block 220 and the second clamping block 230 to move closer or further apart. A space for clamping and releasing the electrode assembly is formed between the first clamping block 220 and the second clamping block 230. When the first clamping block 220 and the second clamping block 230 move closer or further apart, the electrode assembly can be clamped. When the first clamping block 220 and the second clamping block 230 move further apart, the electrode assembly can be released. In this way, the electrode assembly can be picked up and released by driving the first clamping block 220 and the second clamping block 230 to move closer or further apart. This helps to ensure that the force is applied evenly on both sides when the electrode assembly is clamped, better control the clamping force of the electrode assembly, improve the stability of the electrode assembly clamping, and thus achieve efficient and accurate transfer and handover of the electrode assembly.

[0028] The first clamping block 220 and the second clamping block 230 within the gripper unit can move closer to or further away from each other. Various structural forms can achieve this. For example, the first clamping block 220 and the second clamping block 230 can be rotatably configured. When the transmission member 210 rotates, it can drive power to the first clamping block 220 and the second clamping block 230 through gear transmission or other means, thereby causing the first clamping block 220 and the second clamping block 230 to rotate closer to or further away from each other. In this embodiment, for example… Figure 2 and Figure 3 As shown, the gripper unit includes a mounting base 240, a first slide 250, and a second slide 260. The mounting base 240 is connected to the base plate 100. The first slide 250 and the second slide 260 are slidably connected to the mounting base 240, respectively. The middle part of the transmission member 210 is rotatably connected to the first slide 250, and the two ends of the transmission member 210 are respectively drively connected to the first slide 250 and the second slide 260. The first clamping block 220 is connected to the first slide 250, and the second clamping block 230 is connected to the second slide 260. Mounting base 240 is connected to base plate 100 and provides mounting fulcrum for first slide 250 and second slide 260. At this time, first slide 250 and second slide 260 are slidably connected to mounting base 240 respectively. When transmission cam 300 rotates to drive transmission component 210 to rotate, both ends of transmission component 210 provide power to first slide 250 and second slide 260 respectively, so that first slide 250 and second slide 260 slide closer or further away from each other on mounting base 240 in a sliding manner. In this way, first clamping block 220 and second clamping block 230 can be smoothly driven to move closer to each other to clamp the electrode group or move further away from each other to release the electrode group, further improving the stability of picking up and putting down the electrode group.

[0029] In the above embodiment, the transmission cam 300 can directly apply a reciprocating rotational driving force to the transmission component 210, thereby causing the first clamping block 220 and the second clamping block 230 to move closer or further apart. To better maintain the stability of the first clamping block 220 and the second clamping block 230 in gripping the pole pair, in this embodiment, a spring 270 is connected between the first slide block 250 and the second slide block 260. When the first slide block 250 and the second slide block 260 move away from each other, that is, when the first clamping block 220 and the second clamping block 230 release the pole pair, the spring 270 is elastically stretched. When the external force that causes the first slide block 250 and the second slide block 260 to move away from each other is removed, the spring 270 elastically returns to its original state, pulling the first clamping block and the second clamping block closer together, thereby clamping the first clamping block 220 and the second clamping block 230 together.

[0030] When the transmission component 210 rotates, it converts the rotational power into the power to drive the first slide 250 and the second slide 260 to slide. Its structural form can vary. For example, the two ends of the transmission component 210 are respectively connected to connecting rods, and the other ends of the two connecting rods away from the transmission component 210 are respectively rotatably connected to the first slide 250 and the second slide 260. Thus, when the transmission component 210 rotates, it can drive the first slide 250 and the second slide 260 to move closer or further apart via the two connecting rods. In this embodiment, the two ends of the transmission component 210 are respectively provided with a first limiting groove 211 and a second limiting groove. The first slide 250 is connected to a first limiting wheel 251, which is located within the first limiting groove 211. The second slide 260 is connected to a second limiting wheel, which is located within the second limiting groove. When the transmission component 210 rotates, it provides power to the first limiting wheel 251 on the first slide block 250 and the second limiting wheel on the second slide block 260 through its two ends. At this time, the first limiting groove 211 and the second limiting groove can respectively provide space for limiting and moving away from the first limiting wheel 251 and the second limiting wheel. As the transmission component 210 rotates, the first limiting wheel 251 will slide relative to each other in the first limiting groove 211 and the second limiting wheel will slide relative to each other in the second limiting groove. The horizontal offset generated by the rotation of the first limiting wheel 251 and the second limiting wheel with the transmission component 210 can respectively drive the first slide block 250 and the second slide block 260 to move closer or further away from each other, thereby converting the power of the rotation of the transmission component 210 into the power to drive the first slide block 250 and the second slide block 260 to slide.

[0031] Naturally, the transmission cam 300 has a distal end and a proximal end. When the transmission cam 300 rotates, its distal end acts on the transmission component 210, thereby driving the transmission component 210 to rotate. To ensure the stability of the transmission, such as Figure 4As shown, in this embodiment, the transmission member 210 is connected to a transmission wheel 212, and a transmission part 310 is formed on the outer side of the transmission cam 300. The transmission part 310 has guide slopes 311 formed on both sides of the base plate 100 in the rotation direction. The two guide slopes 311 are inclined from top to bottom in a direction that approaches each other. When the base plate 100 rotates, the transmission wheel 212 abuts against the guide slopes 311. When the transmission cam 300 rotates relative to the base plate 100, the transmission part 310 on the outer side of the transmission cam 300 passes through the gripper unit. Since the transmission part 310 has guide slopes 311 on both sides of the base plate 100 in the rotation direction, regardless of whether the transmission cam 300 rotates clockwise or counterclockwise relative to the base plate 100, when the guide slope 311 on the transmission part 310 abuts against the transmission wheel 212 on the transmission member 210, the transmission member 210 abuts against the transmission wheel 212 through its guide slopes 311. Because the guide slopes 311 are inclined... As the transmission component 210 rotates, the pressure of the guide slope 311 on the transmission wheel 212 gradually increases, and the transmission wheel 212 drives the transmission component 210 to rotate. When the transmission component 210 drives the transmission wheel 212 to move along the guide slope 311 to the bottom of the transmission component 210, the transmission wheel 212 can pass over the bottom of the transmission component 210 and abut against the guide slope 311 on the other side. At this time, it can assist the transmission component 210 to rotate in the opposite direction, thus stably driving the first slide 250 and the second slide 260 to move closer or further apart.

[0032] There may be only one transmission unit 310 on the transmission cam 300. However, in some production equipment, depending on different processing needs, there may be situations where multiple pole groups need to be picked up and placed simultaneously. In this case, the number of transmission units 310 can be multiple to correspond to the required workstation. Specifically, multiple transmission units 310 are arranged around the rotation axis of the base plate 100. When the transmission cam 300 rotates relative to the base plate 100, the multiple transmission units 310 on its outer side can drive the gripper unit respectively, thereby enabling multiple gripper units to pick up and place pole groups simultaneously, better meeting the needs of production.

[0033] There are several ways to rotate the transmission cam 300 relative to the base plate 100. For example, the base plate 100 can be fixed while the transmission cam 300 rotates, or the base plate 100 can be rotated while the transmission cam 300 is fixed. In this embodiment, the latter method of rotating the base plate 100 and fixing the transmission cam 300 is used. To drive the base plate 100, this utility model also includes a spindle 400, the top of which passes through... Since the spindle 400 passes through the base plate 100 and is synchronously connected to it, it is natural that the spindle 400 is connected and fixed to the base plate 100 at the position where it passes through the base plate 100, so that the spindle 400 and the base plate 100 can rotate synchronously. The transmission cam 300 is rotatably connected to the top of the spindle 400. In order to facilitate the installation of the transmission cam 300, an annular step can be formed on the outer side of the end of the spindle 400. The transmission cam 300 is connected to the annular step through a bearing, so that the transmission cam 300 can be quickly and stably installed on the top of the spindle 400. The spindle 400 is synchronously connected to the base plate 100. External power can drive the base plate 100 to rotate through the spindle 400. The transmission cam 300 is rotatably connected to the end of the spindle 400 that protrudes from the base plate 100. At this time, the transmission cam 300 can be positioned by the external structure. The base plate 100 rotates while the transmission cam 300 remains stationary, thus realizing the rotation of the transmission cam 300 relative to the base plate 100.

[0034] To facilitate the positioning of the mandrel 400, this utility model also includes a bushing 410, which is connected to the outside of the mandrel 400. The bushing 410 can be connected to an external structural component. In this case, the mandrel 400 is located inside the bushing 410 and can rotate relative to the bushing 410, thus assisting in positioning the mandrel 400 and improving the stability of its rotation. In practical applications, a connecting flange can be provided on the outside of the bushing 410, allowing for easy fixing of the bushing 410 to the external structural component.

[0035] There are several ways to drive the spindle 400 to rotate. For example, the output shaft of the motor can be directly and synchronously connected to the spindle 400, or it can be connected to the spindle 400 via belt drive. In this embodiment, the spindle 400 is driven to rotate via gear drive. Specifically, a transmission gear 420 is connected to the bottom end of the spindle 400. External power can drive the spindle 400 to rotate by meshing with the transmission gear 420, thereby improving the stability and controllability of the spindle 400 driving the base plate 100 to rotate.

[0036] In some embodiments, the transmission cam 300 is provided with a fixing hole 320. Screws, bolts or other connecting parts of the external device can be driven into the fixing hole 320 to fix the transmission cam 300 to the structural parts of the external device, thereby facilitating the positioning of the transmission cam 300.
