Currently, hot pressing and restrained formation equipment is generally used to process lithium batteries during the formation stage.

[0003] The existing layer plate assembly of the hot pressing restraint forming device generally includes a layer plate and two layer plate hangers. The layer plate hangers include a mounting member and a hanger body arranged at one end of the mounting member. The mounting members of the two layer plate hangers are respectively arranged at both ends of the layer plate. The hanger body is provided with a through hole. The hanger bodies of the two layer plate hangers are respectively used to be mounted on the outer periphery of the two guide rods of the hot pressing restraint forming device through their respective through holes. In actual application, when the layer plate of the layer plate assembly is driven by the driving assembly of the hot pressing restraint forming device to move the layer plates to pressurize the lithium battery between the layer plates of two adjacent layer plate assemblies, the movement of the layer plates can drive the mounting members of the two layer plate hangers to move synchronously, thereby driving the hanger bodies of the two layer plate hangers to move along the corresponding guide rods respectively. Since the mount body is in direct contact with the guide rod when it moves along the corresponding guide rod, the mount body moves less smoothly along the corresponding guide rod, thereby reducing the stability of the movement of the layer mount, and further reducing the stability of the movement of the layer, making the layer prone to shaking, resulting in unstable pressurization of the lithium battery, reducing the quality of the lithium battery, and large friction, so a large-power drive component is required to drive the layer to move, and the use of a high-power drive component increases production costs.

[0024] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technical personnel in this field without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the present invention can be combined interactively without conflicting with each other.

[0025] Please refer to Figures 1 to 3 The utility model provides a layer plate hanger according to an embodiment, comprising a mounting member 10, a hanger body 20 arranged at one end of the mounting member 10, and a rolling structure. The mounting member 10 is used to be arranged on the layer plate 100 (see Figure 6 and Figure 7 ) at one end.

[0026] A through-hole 21 is provided at the center of the mount body 20. The mount body 20 is designed to be mounted, through this through-hole 21, on the outer periphery of a guide rod of a hot-pressing constrained formation device. A rolling structure is provided on the inner wall of the through-hole 21 and is configured to engage with the outer periphery of the guide rod. In practical application, when the mounting member 10 is driven to move synchronously by the layer plate 100, the mounting member 10 can also drive the mount body 20 to move synchronously, thereby driving the rolling structure to move along the guide rod in a rolling manner. The rolling structure's rolling movement along the guide rod provides support for the movement of the mount body 20, thereby improving the smooth movement of the mount body 20, the layer plate mount, and the layer plate 100. This, in turn, improves the smooth movement of the layer plate 100, reduces the wobble of the layer plate 100, and enhances the stability of pressurization of the lithium battery, thereby improving the quality of the lithium battery. Furthermore, the rolling friction between the rolling structure and the outer periphery of the guide rod is low, eliminating the need for a high-power drive assembly to drive the layer plate, reducing production costs and reducing noise.

[0027] Specifically, the rolling structure includes four rolling elements: a first rolling element 31, a second rolling element 32, a third rolling element 33, and a fourth rolling element 34.

[0036] Combine Figure 4 and Figure 5 As shown, the bottom of the first recess is detachably provided with two first limiting pieces 215. The two first limiting pieces 215 respectively contact the two ends of the third connecting rod 2131. Thus, the two first limiting pieces 215 can respectively limit the two ends of the third connecting rod 2131 to prevent the two ends of the third connecting rod 2131 from respectively falling out of the two third slots 2132. The bottom of the second recess is detachably provided with two second limiting pieces 217. The two second limiting pieces 217 respectively contact the two ends of the fourth connecting rod 2141. Thus, the two second limiting pieces 217 can respectively limit the two ends of the fourth connecting rod 2141 to prevent the two ends of the fourth connecting rod 2141 from respectively falling out of the two fourth slots 2142.

[0037] Two first limiting pieces 215 are detachably provided at the bottom of the first recess, and two second limiting pieces 217 are detachably provided at the bottom of the second recess.

[0038] The above structure facilitates replacement of the first rolling element 31, the second rolling element 32, the third rolling element 33, and the fourth rolling element 34 when they become worn. To replace the first rolling element 31, the second rolling element 32, the third rolling element 33, and the fourth rolling element 34, the first fastener 241 is first removed, the second portion 24 is then removed from the first portion 23, and one end of the first connecting rod is separated from the first slot of the second portion 24, and one end of the second connecting rod is separated from the second slot of the second portion 24. The other end of the first connecting rod is then removed from the first slot of the first portion 23, and the other end of the second connecting rod is removed from the second slot of the first portion 23. The first rolling element 31 and the second rolling element 32 are then removed from the first portion 23. Then, the new first rolling element 31 and the second rolling element 32 are respectively mounted on the outer periphery of the first connecting rod and the outer periphery of the second connecting rod. The other ends of the first connecting rod and the other ends of the second connecting rod are then inserted into the first slot and the second slot of the first portion 23, respectively. The two second fasteners 216 and the two second limiting plates 215 are then removed from the first portion 23. The third connecting rod 2131 and the third rolling element 33 are then removed from the first portion 23. The new third rolling element 33 is then mounted on the outer periphery of the third connecting rod 2131. The new third rolling element 33 is then placed into the third mounting groove 213 and the two ends of the third connecting rod 2131 are respectively placed into the two third slots 2132 of the first portion 23. The two first limiting plates 215 and the two second fasteners 216 are then reinstalled on the first portion 23. Then, remove the two third fasteners 218 and the two second limiting plates 217 from the second portion 24. Then, remove the fourth connecting rod 2141 and the fourth rolling element 34 from the second portion 24. Then, fit the new fourth rolling element 34 around the outer circumference of the fourth connecting rod 2141. Then, insert the new fourth rolling element 34 into the fourth mounting slot 214. Then, insert the two ends of the fourth connecting rod 2141 into the two fourth slots 2142 of the second portion 24. Then, reinstall the two second limiting plates 217 and the two second fasteners 217 onto the second portion 24. Then, align the end of the second portion 24 closer to the mounting member 10 with the end of the first portion 23 farther from the mounting member 10. Insert one end of the first connecting rod into the first slot of the second portion 24, and one end of the second connecting rod into the second slot of the second portion 24. Finally, install the first fastener 241. The replacement is now complete.

[0039] In this embodiment, there are two first rolling elements 31 and two second rolling elements 32, each spaced apart along the width of the mount body 20. There is one third rolling element 33 and one fourth rolling element 34. The number of first connecting rods, the number of first slots in the first portion 23, and the number of first slots in the second portion 24 correspond to the number of first rolling elements 31.

The number of third connecting rods 2131 corresponds to the number of third rolling elements 33, and the number of fourth connecting rods 2141 corresponds to the number of fourth rolling elements 34.

[0040] In an alternative solution, the rolling structure is replaced by a sliding structure, which is arranged in the through hole 21 and is used to slide around the outer periphery of the guide rod. In actual application, when the mounting member 10 is driven to move synchronously by the layer plate 100, the mounting member 10 can drive the mount body 20 to move synchronously, thereby driving the sliding structure to slide along the guide rod. By sliding the sliding structure along the guide rod, it is also possible to provide support for the movement of the mount body 20, thereby improving the stability of the movement of the mount body 20, thereby improving the stability of the movement of the layer plate mount, and further improving the stability of the movement of the layer plate 100, reducing the shaking of the layer plate 100, and improving the stability of pressurizing the lithium battery, thereby improving the quality of the lithium battery. In addition, there is sliding friction between the sliding structure and the outer periphery of the guide rod, and the friction force is small. There is no need to use a high-power drive component to drive the layer plate, which reduces production costs.

[0041] Specifically, the sliding structure includes a sliding sleeve, which is arranged in the through hole 21 and is used to slide around the outer periphery of the guide rod. In actual application, the mount body 20 can drive the sliding sleeve to slide along the guide rod.

[0042] It is understandable that the sleeve can also be replaced by a linear bearing. The cross-sectional shape of the through hole 21 is adapted to the cross-sectional shape of the linear bearing or the sleeve.

[0043] Please refer to Figure 6 and Figure 7The present invention also provides a layer plate assembly, including a layer plate 100, two of the above-mentioned layer plate hangers, a first conductive structure 110 and a second conductive structure 120. The two layer plate hangers are symmetrical about the center of the layer plate 100. The other ends of the mounting parts 10 of the two layer plate hangers are respectively arranged at both ends of the layer plate 100. The mounting parts 10 partially protrude from the bottom end of the layer plate 100. By adopting the above-mentioned layer plate hangers, in actual application, the smoothness of the movement of the layer plate 100 can be improved, the shaking of the layer plate 100 can be reduced, and the stability of pressurizing the lithium battery can be improved, thereby improving the quality of the lithium battery and reducing the production cost. It is not necessary to use a high-power drive component to drive the layer plate 100, thereby reducing the production cost.

[0044] In this embodiment, two mounting positions 102 are respectively provided at both ends of the layer plate 100, and the other ends of the mounting parts 10 of the two layer plate hangers are respectively arranged at the bottom of the two mounting positions 102. The structure is compact and can reduce the overall length of the layer plate assembly, thereby reducing the volume of the hot pressing restraint forming device.

[0045] Two silicone pads 101 are respectively provided on one side and the other side of the layer plate 100. The two silicone pads 101 can play a buffering role when the lithium battery is actually pressurized to avoid damage to the lithium battery.

[0046] The first conductive structure 110 and the second conductive structure 120 correspond to two layer board mounts, respectively. The first conductive structure 110 and the second conductive structure 120 each include a first connecting plate 111, a second connecting plate 112, and a PCB 113. The first connecting plate 111 is disposed at one end of the mounting member 10 of the corresponding layer board mount and is located below the mount body 20 of the corresponding layer board mount. The second connecting plate 112 of the first conductive structure 110 contacts one side of the layer board 100, and the second connecting plate 112 of the second conductive structure 120 contacts the other side of the layer board 100. A connecting portion 1121 is formed at one end of the second connecting plate 112 away from the layer board 100, and the connecting portion 1121 is connected to the first connecting plate 111. The PCB 113 is disposed on the side of the second connecting plate 112 away from the layer board 100. PCB113 is used to contact the positive electrode or negative electrode of the lithium battery and to be electrically connected to an external power source through a wire, so that the lithium battery can be charged and discharged by the external power source through the wire and PCB113, thereby realizing the formation treatment of the lithium battery.

[0047] The second connecting plate 112 and the connecting portion 1121 are integrally formed to facilitate manufacturing. The second connecting plate 112 and the connecting portion 1121 form an L-shaped structure.

[0048] The present invention also provides a hot pressing restraint formation device, including the above-mentioned layer plate assembly. By adopting the above-mentioned layer plate assembly, the stability of pressurizing the lithium battery is improved, thereby improving the quality of the lithium battery and reducing the production cost. It is not necessary to use a high-power driving assembly to drive the layer plate 100, thereby reducing the production cost.
