Description

Technical Field

[0001] This utility model belongs to the technical field of lithium battery manufacturing equipment, and specifically relates to a pressure holding and transfer fixture for a stacking machine. Background Technology

[0002] Currently, compared to conventional stacked core package feeding, mini core packages have the problem of being small in size and difficult to grip. Furthermore, when using a feeding mechanism to feed mini core packages, the feeding mechanism is prone to affecting the retraction of the stacking pressure knife, resulting in poor core package feeding stability and affecting the production efficiency and quality of core packages. Utility Model Content

[0003] The purpose of this utility model is to provide a pressure holding and transfer fixture for a stacking machine to solve one or more technical problems existing in the prior art.

[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows: This utility model discloses a pressure holding and transfer fixture for a wafer stacking machine, comprising: A base having a connecting end that connects to a stacking table; A cover is connected to the base. The cover is provided with a deformable part and a pressing part. The deformable part is located below the cover and its two ends are respectively connected to the cover. The pressing part slides on the cover and is in contact with the deformable part. The deformable element includes a flat state and a convex state. The deformable element is configured such that when the pressing element is pressed down, the deformable element changes from the flat state to the convex state and presses tightly against the core package located between the base and the cover; when the pressing element is released, the deformable element returns from the convex state to the flat state.

[0005] The present invention has at least the following beneficial effects: the connecting end of the base is connected to the stacking table, so that the base and the stacking table are relatively fixed, and the stacking robot can stably pick up and adsorb the thermally composited positive electrode sheet and the un-thermally composited negative electrode sheet in sequence and place them on the base, so that the core package is stacked on the base to form a core.

[0006] After the core package is stacked and formed, the cover is connected to the base. At this time, the output end of the material handling mechanism can clamp the pressure holding and transfer fixture of the stacking machine. At the same time, the output end of the material handling mechanism can press down the pressing component. The pressed pressing component causes the deformable component to bulge downward, so that the deformable component is in a bulging state. The bulging end of the deformable component presses the core package tightly onto the base. Since the bulging end of the deformable component and the stacking pressure knife act on different positions of the core package, while ensuring the stability of the core package, the pressure holding and transfer fixture of the stacking machine can make the stacking pressure knife loosen the electrode and pull it out of the core package, preventing friction interference between the stacking pressure knife and the deformable component when it is pulled out. It can also transfer the end that presses the core package from the stacking pressure knife to the deformable component, improving the stability of core package feeding, thereby improving the production efficiency and production quality of the core package.

[0007] When the output end of the material handling mechanism picks up the pressure-holding and transfer fixture of the stacking machine to the hot pressing station, the output end of the material handling mechanism releases the pressure-holding and transfer fixture and the pressing component. At this time, the deformed component springs back to a flat state, and the output end of the hot pressing mechanism can simultaneously press down the cover and the pressing component, so that the cover and the pressing component are relatively fixed and simultaneously press down the core package. The cover and the base are relatively fixed. The core package is hot-pressed while ensuring the stability of the core package stacking structure. Since the deformed component covers the core package, the hot pressing process will not cause scratches on the surface of the core package, thus improving the production quality of the core package.

[0008] As a further improvement to the above technical solution, both ends of the cover have stoppers extending outwards, and both ends of the cover have connecting ports. The connecting ports are located above the stoppers, and the deformable member passes through the connecting ports and connects with the stoppers.

[0009] As a further improvement to the above technical solution, the stop member is provided with a fixing bolt and a fixing screw hole, and the fixing bolt passes through one end of the deformable member and is threaded into the fixing screw hole.

[0010] As a further improvement to the above technical solution, the connecting port extends obliquely and its two ends are respectively connected to the lower end face of the cover and one of its side end faces.

[0011] As a further improvement to the above technical solution, the cover is provided with a sliding groove extending vertically, the pressing member slides in the sliding groove, and the upper end of the pressing member is the pressing end pressed down by the output end of the material taking mechanism.

[0012] As a further improvement to the above technical solution, the deformable component is a spring steel plate.

[0013] As a further improvement to the above technical solution, the base and the cover are connected by pins and pin holes, and the base is provided with a connecting part that is connected to the stacking table by pins and pin holes, and the connecting part is set as the connecting end.

[0014] As a further improvement to the above technical solution, the cover is provided with a first positioning pin on the side facing the base, and the base is provided with a first positioning hole corresponding to the first positioning pin.

[0015] As a further improvement to the above technical solution, the connecting end is a second positioning hole, which is configured to allow the second positioning pin of the stacking stage to pass through.

[0016] As a further improvement to the above technical solution, two of each of the first and second positioning holes are provided, and the two first positioning holes and the two second positioning holes are staggered and distributed in a rectangular array. Attached Figure Description

[0024] Reference Figures 1 to 7 The following are several embodiments of the stacking machine pressure holding and transfer fixture of this utility model.

[0025] like Figures 1 to 7 As shown, the stacking machine pressure holding and transfer fixture 100 of this utility model embodiment, hereinafter referred to as the fixture, includes a base 200 and a cover 300 for positioning and connection.

[0026] Understandably, the base 200 has a connecting end, which is used to position and connect with the stacking stage, ensuring that it is placed stably and accurately on the stacking stage and preventing displacement during the stacking of the core package 700. The upper surface of the base 200 is the working surface 230 for stacking the core package 700. The stacking robot picks up and adsorbs the thermally bonded positive electrode sheet and the un-thermally bonded negative electrode sheet at once and places them on the working surface 230, so that the core package 700 is stacked into shape.

[0027] Understandably, after the core package 700 is stacked and formed on the working surface 230, the cover 300 covers the base 200, and the two are positioned and connected to stabilize the relative position of the cover 300 and the base 200, preventing misalignment. The cover 300 is provided with a deformable element 310 and a pressing element 400. Specifically, the deformable element 310 is located below the cover 300, and its two ends in the left and right directions are respectively connected to the cover 300 to prevent the deformable element 310 from detaching from the cover 300 and to ensure that the deformable element 310 is stably connected to the lower end face of the cover 300. The pressing element 400 is located in the middle of the cover 300 and is slidably connected to the cover 300. The pressing element 400 and the middle of the deformable element 310 are vertically opposite and connected.

[0028] It is understandable that the deformable part 310 includes a flat state and a convex state. Specifically, when the output end of the feeding mechanism presses the pressing part 400 from top to bottom, the lower end of the pressing part 400 moves down and extends out of the lower end face of the cover 300. The middle part of the deformable part 310 undergoes elastic deformation and convexes downward under the action of the pressing part 400, such as... Figure 2 and Figure 6 As shown, at this time, the deformable part 310 changes from a flat state to a convex state. The convex deformable part 310 presses the core package 700 tightly, so that the core package 700 is clamped between the deformable part 310 and the working surface 230, thereby stably fixing the stacked core package 700 in the stacking machine pressure holding and transfer fixture 100.

[0029] Because the stacking pressure knife presses tightly against the left and right ends of the core package 700, when the deformable part 310 changes to a downward convex state, the middle part of the deformable part 310 convexes downward and presses tightly against the middle part of the core package 700. At this time, the stacking pressure knife can loosen the electrode sheets and pull them out of the core package 700. The core package 700 always maintains a stable stacked state without misalignment through the middle part of the deformable part 310. When the stacking pressure knife is pulled out, it can avoid frictional interference with the deformable part 310, thus preparing for the next step of transferring the core package 700.

[0030] In addition to pressing down the pressing component 400, the output end of the material handling mechanism can also clamp and transfer the stacking machine pressure holding and transfer fixture 100 and the core package 700 together to the hot pressing station. During the clamping and transfer process, the output end of the material handling mechanism always presses down the pressing component 400, so that the deformable component 310 keeps pressing the core package 700 tightly to maintain the stability of the stacked structure of the core package 700.

[0031] When the output end of the material handling mechanism moves into position, it releases the fixture, the pressing part 400 is no longer pressed down, and the deformable part 310 springs back to its original position. At this time, the deformable part 310 changes from a convex state to a flat state. As it recovers, the deformable part 310 drives the pressing part 400 to move upward, so that the lower end of the pressing part 400 moves into the cover 300. Then, the hot pressing mechanism is activated, and its output end presses the cover 300 and the pressing part 400 downward, so that the cover 300 and the pressing part 400 press the core package 700 with a flat plane, thereby stably clamping the core package 700 and realizing the hot pressing process on the core package 700.

[0032] This configuration allows the stacking machine's pressure-holding transfer fixture 100 to easily retract the stacking pressure knife while ensuring the core package remains stable during retraction, thus improving the stability of core package feeding and further enhancing core package production efficiency and quality. Furthermore, the stacking machine's pressure-holding transfer fixture 100 prevents electrode misalignment during the transfer of the formed core package 700 due to external forces or other factors, while also improving the stability of the core package 700's stacked structure, further enhancing core package 700 production efficiency and quality. During hot pressing, the fixture and core package 700 can be directly fed into the hot pressing station together. Utilizing the fixture enhances market competitiveness, optimizes resource utilization, and better adapts to industry development trends and meets personalized production needs.

[0033] It is understandable that the cover 300 has stop members 320 extending from both ends in the left-right direction in a direction away from each other, that is, both the left and right ends of the cover 300 are connected to stop members 320, such as Figures 1 to 3 As shown. The cover 300 has connecting openings 330 at both ends along the left and right directions. The connecting openings 330 are located above the stop 320, as shown. Figure 1 , Figure 3 and Figure 6 As shown. The left end of the deformable part 310 passes through the left-side connecting port 330 and connects to the left-side stop 320. The right end of the deformable part 310 passes through the right-side connecting port 330 and connects to the right-side stop 320. The connection between the deformable part 310 and the cover 300 is actually the connection between the deformable part 310 and the stop 320. The stop 320 effectively prevents the deformable part 310 from coming out of the connecting port 330.

[0034] In some embodiments, the deformable member 310 and the stop member 320 can be connected by welding, snap-fitting, or other methods.

[0035] In this embodiment, the stop 320 is provided with a threaded fixing bolt 340 and a fixing screw hole. Correspondingly, the deformable part 310 is provided with connecting holes at both ends extending outside the two connecting ports. The connecting holes correspond to the fixing screw holes. The fixing bolt 340 passes through the connecting holes and the fixing screw holes from top to bottom. The stop 320 and the deformable part 310 are connected by bolt connection.

[0036] It is understandable that each stop 320 has three fixing screw holes and three fixing bolts 340. Correspondingly, the left and right ends of the deformation part 310 are provided with three connecting holes. The three connecting holes are spaced apart in the front-back direction to ensure a stable connection between the stop 320 and the deformation part 310.

[0037] In some embodiments, the connecting port 330 is disposed between the cover 300 and the stop 320. Specifically, the upper end face of the stop 320 is lower than the lower end face of the cover 300, the connecting port 330 extends horizontally in the left and right directions, the upper end of the connecting port 330 is flush with the lower end of the cover 300, the lower end of the connecting port 330 is flush with the upper end of the stop 320, and the two ends of the deformable member 310 are respectively provided with two connecting ports 330 in the horizontal direction. When the deformable member 310 is in a flat state, the deformable member 310 is set horizontally as a whole.

[0038] In this embodiment, the connecting port 330 is inclined. Specifically, the connecting port 330 located at the left end of the cover 300 connects to the lower end face and the left end face of the cover 300, and the connecting port 330 located at the right end of the cover 300 connects to the lower end face and the right end face of the cover 300. The upper end of the stop member 320 is flush with the lower end of the connecting port 330 on the side end face of the cover 300, and the lower end face of the stop member 320 is flush with the lower end face of the cover 300. The left end of the deformable member 310 is inclined upward through one connecting port 330, and the right end of the deformable member 310 is inclined upward through another connecting port 330. The middle part of the deformable member 310 is horizontally positioned and fits against the lower end face of the cover 300 and the lower end face of the pressing member 400.

[0039] It is understandable that the two connecting ports 330 on the cover 300 are symmetrically arranged in the left-right direction, and the two stoppers 320 are also symmetrically arranged in the left-right direction.

[0040] Understandably, the cover 300 has a groove 500 in the middle, such as... Figure 1 , Figure 4 , Figure 6 and Figure 7As shown, the slide groove 500 extends vertically and connects the upper and lower surfaces of the cover 300. The pressing member 400 is embedded in the slide groove 500 and slides up and down along the slide groove 500. The upper end of the pressing member 400 is the pressing end pressed down by the output end of the material handling mechanism. In this way, the output end of the material handling mechanism can press down the pressing end, causing the pressing member 400 to move downward relative to the cover 300, thereby squeezing the middle of the deformable member 310 downward and pressing the core package 700 tightly. When the output end of the material handling mechanism releases the pressing end, the rebound effect of the deformable member 310 is greater than the gravity effect of the pressing member 400. Therefore, the deformable member 310 drives the pressing member 400 to move upward, causing the pressing member 400 to return to the slide groove 500.

[0041] In some embodiments, the slide 500 is a straight groove that guides the pressing member 400, so that the pressing member 400 can slide up and down accurately and without restriction.

[0042] In other embodiments, the groove 500 is a stepped groove that is smaller at the top and larger at the bottom, and correspondingly, the pressing member 400 is an inverted T-shaped block. Thus, the output end of the material handling mechanism can move the pressing member 400 downwards without restriction, and the downward stroke of the pressing member 400 can be controlled by controlling the output end of the material handling mechanism. When the deformable member 310 springs back to its flat state and moves the pressing member 400 upwards, the pressing member 400 is kept stably within the groove 500, preventing it from popping out from the upper end of the groove 500.

[0043] In this embodiment, the chute 500 is a stepped chute that is wider at the top and narrower at the bottom, and the corresponding pressing member 400 is a T-shaped block. This ensures that the output end of the material handling mechanism has sufficient downward pressure area, allowing it to press down on the pressing member 400. The stepped chute 500, with its wider top and narrower bottom, limits the downward stroke of the pressing member 400, preventing a malfunction at the output end of the material handling mechanism from causing the pressing member 400 and the deforming member 310 to move downwards and damage the core package 700.

[0044] Furthermore, the vertical height of the slide groove 500 is equal to the vertical height of the pressing member 400. The upper height of the stepped slide groove 500 is greater than the upper height of the T-shaped pressing member 400, and the lower height of the stepped slide groove 500 is less than the lower height of the T-shaped pressing member 400, ensuring that the lower end of the pressed member 400 can extend out of the slide groove 500, so that the deformable member 310 is in a convex state.

[0045] It is understandable that the horizontal cross-section of the slide 500 can be circular, triangular, or square, and correspondingly, the horizontal cross-section of the pressing part 400 can be circular, triangular, or square.

[0046] In this embodiment, the groove 500 is a stepped quadrangular prism groove, and correspondingly, the horizontal cross section of the pressing member 400 is a square extending in the front-back direction, ensuring that the pressing member 400 stably extrudes the deforming member 310.

[0047] It is understandable that the front-to-back length of the pressing member 400 is greater than or equal to the front-to-back length of the deforming member 310, so that the pressing member 400 can fully drive the middle part of the deforming member 310 to bulge downward, ensuring that the deforming member 310 covers the core package 700 during the transfer or hot pressing process, and improving the stability of the core package 700 stacked structure in the fixture.

[0048] In this embodiment, the output end of the material handling mechanism is a material handling robot. The material handling robot can press down the pressing end and also grip both ends of the base 200, thereby transferring the fixture to the hot pressing station while keeping the deformed part 310 tightly pressing the core package 700.

[0049] In this embodiment, the deformable member 310 is a spring steel plate with resilience and ductility. Both the pressing member 400 and the stop member 320 are plate-shaped structures. The plate-shaped pressing member 400 can reduce the heat loss of the hot pressing mechanism.

[0050] In some embodiments, the base 200 and the cover 300 can be positioned and connected by means of screws, bolts, or snap-fits. However, the connection process requires tightening screws, bolts, or shifting snap-fits, making the positioning between the base 200 and the cover 300 somewhat inconvenient.

[0051] In this embodiment, the base 200 and the cover 300 are connected by a pin and a pin hole for positioning. Specifically, the cover 300 has a first positioning pin 350 on the side facing the base 200, that is, the lower end face of the cover 300 has a first positioning pin 350, such as... Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown. Correspondingly, the base 200 has a first positioning hole 210 on the side facing the cover 300, that is, the upper end surface of the base 200 has a first positioning hole 210, as shown. Figure 1 , Figure 5 and Figure 7 As shown, the first positioning pin 350 and the first positioning hole 210 are vertically opposite each other. After the core package 700 is stacked on the working surface 230, the cover 300 is placed. At this time, the first positioning pin 350 passes through the first positioning hole 210 to realize the positioning of the cover 300 and the base 200. When the output end of the material picking mechanism presses down the pressing part 400, the cover 300 and the base 200 are always relatively fixed to avoid the deformation part 310 from shifting, which would cause the deformation part 310 to fail to accurately press the core package 700.

[0052] Similarly, the base 200 and the stacking table are positioned and connected by screws, bolts, or clips. However, the connection process requires tightening screws, bolts, or shifting clips, making the positioning between the base 200 and the stacking table inconvenient. Furthermore, before the output end of the material handling mechanism can move the fixture to the hot pressing station, the screws need to be tightened or the clips shifted, making the transfer process inconvenient.

[0053] In this embodiment, the base 200 is provided with a connecting part, and the connecting part and the stacking platform are also positioned and connected by pins and pin holes. The connecting part is the connecting end. Specifically, the lower end face of the base 200 is provided with a second positioning hole 220, such as... Figure 1 , Figure 5 and Figure 7 As shown, the second positioning hole 220 is the connecting end of the base 200. Correspondingly, the stacking table is provided with a second positioning pin 600 that is vertically opposite to the second positioning hole 220, as shown. Figure 1 and Figure 5 As shown, the connection between the base 200 and the stacking table is achieved by the second positioning hole 220 fitting onto the second positioning pin 600. The lower end face of the base 200 is in contact with the upper end face of the stacking table. The second positioning hole 220 and the second positioning pin 600 ensure relative stability between the base 200 and the stacking table, preventing misalignment of the base 200 and the stacking table during the stacking process of the core package 700, which would affect the stacking accuracy of the stacking robot on the base 200. When the output end of the picking mechanism transfers the fixture, the output end of the picking mechanism can clamp and lift the base 200 upwards, thereby disengaging the second positioning pin 600 from the second positioning hole 220, achieving simple and quick fixture transfer.

[0054] Understandably, the hot pressing mechanism can also be equipped with a second positioning pin 600 opposite to the base 200, so that the base 200 is positioned on the hot pressing mechanism, ensuring that the output end of the hot pressing mechanism is vertically aligned with the pressing part 400, and the hot pressing process is carried out accurately.

[0055] In other embodiments, the base 200 is provided with a first positioning pin 350 and a second positioning pin 600, the cover 300 is provided with a first positioning hole 210, and the stacking table is provided with a second positioning hole 220.

[0056] It is understood that the first positioning hole 210 and the second positioning hole 220 can be blind holes or through holes. In this embodiment, both the first positioning hole 210 and the second positioning hole 220 are through holes. After passing through the first positioning hole 210, the first positioning pin 350 abuts against the stacking table, so that the lower end face of the cover 300 and the upper end face of the base 200 are spaced apart. When the deformable part 310 is in a flat state, the deformable part 310 and the stacked core package 700 are spaced apart.

[0057] It is understood that one or more of the first positioning hole 210 and the second positioning hole 220 may be provided. In this embodiment, two first positioning holes 210 and two second positioning holes 220 are provided to reinforce the positioning connection between the base 200, the cover 300, and the stacking table.

[0058] In some embodiments, the two first positioning holes 210 may be spaced apart along the front-back direction or the left-right direction, and the arrangement of the two second positioning holes 220 is the same as that of the two first positioning holes 210.

[0059] In this embodiment, the base 200 has a cuboid structure, meaning it has four corners. Two first positioning holes 210 and two second positioning holes 220 are staggered and arranged in a rectangular array. Specifically, the two first positioning holes 210 are located at two opposite corners of the base 200 along a diagonal, and the two second positioning holes 220 are located at two corners of the base 200 along another focusing line. This further improves the connection stability between the base 200 and the cover 300 and the stacking stage. Figure 5 As shown.
