[0033] Referring to Figures 1 to 3 , Figure 1 Figure 1 is a structural schematic view of the layer plate assembly of the guide assembly and the battery formation clamp in an embodiment of the present application, Figure 2 Figure 2 is an exploded view of the guide assembly, Figure 1 Figure 3 is an exploded view of the guide sleeve of the guide assembly in the embodiment, Figure 3 Figure 4 is a schematic view of the guide assembly, Figure 1 Figure 5 is a schematic view of the guide sleeve of the guide assembly,

[0034] As shown in Figures 1 to 3 , the embodiment of the present application proposes a guide assembly 100 for a battery formation clamp, the battery formation clamp comprising a layer plate 200 for clamping a battery, the guide assembly 100 comprising:

[0035] a guide rod 110;

[0036] a guide sleeve 120 sleeved on the guide rod 110 and in sliding fit with the guide rod 110, the peripheral wall of the guide sleeve 120 being configured with a cut 121 cutting the peripheral wall along the axial direction;

[0037] a connecting seat 130 sleeved on the guide sleeve 120 and slidable with the guide sleeve 120 relative to the guide rod 110, the connecting seat 130 being used for connecting with the layer plate 200.

[0038] The guide assembly 100 involved in the embodiment is applied to the battery formation clamp, and is used for connecting with the layer plate 200 thereof to realize the guidance of the movement of the layer plate 200 in the movement process of the layer plate 200. Specifically, the battery formation clamp comprises the guide rod 110, the guide sleeve 120 and the connecting seat 130, wherein the guide sleeve 120 is sleeved on the guide rod 110, and a gap fit can be adopted between the guide sleeve 120 and the guide rod 110 to adapt to the possible slight size change of the guide rod 110 under different working conditions, while ensuring the sliding accuracy of the guide sleeve 120 on the guide rod 110. The connecting seat 130 and the guide sleeve 120 are assembled together, and the guide sleeve 120 is relatively fixed with the connecting seat 130. As Figure 1As shown, the connecting seat 130 is used to connect with the layer plate 200, and the connection mode can be, for example, screw connection, but is not limited thereto. When the layer plate 200 moves, the connecting seat 130 slides relative to the guide rod 110 along with the guide sleeve 120 to guide the movement of the layer plate 200.

[0039] As shown in the above formula (1), the formula (1) is used to calculate the length of the guide sleeve 120. Figure 2 and Figure 3 As shown, the peripheral wall of the guide sleeve 120 is configured with a cutout 121 that cuts the peripheral wall along the axial direction of the guide sleeve 120. The number of the cutout 121 can be one or multiple, and the present embodiment does not limit this. When the guide sleeve 120 is worn, the guide sleeve 120 can be easily disassembled and replaced from the guide rod 110, because the peripheral wall of the guide sleeve 120 is configured with the cutout 121 that cuts the peripheral wall, and only needs to be separated and opened at the position of the cutout 121 of the guide sleeve 120. Compared with the prior art, the replacement process of the guide sleeve 120 is simple, time-saving and labor-saving, and can improve the production efficiency.

[0040] In daily use, the two side edges of the cutout 121 of the guide sleeve 120 are in a split state, and the split form can include various forms, such as a concave-convex matching form, which can be:

[0041] In some embodiments, as shown in the above formula (2), the formula (2) is used to calculate the length of the guide sleeve 120. Figure 3As shown, one of the two side edges of the cutout 121 is provided with a protrusion 1211, and the other is provided with a groove 1212 matched with the protrusion 1211, and the protrusion 1211 is accommodated in the groove 1212 to form a splicing fit. The protrusion 1211 can be provided in various shapes, such as semicircular, trapezoidal or rectangular, and the groove 1212 is designed to be matched with the shape of the protrusion 1211 to ensure that the protrusion 1211 can be smoothly embedded in the groove 1212 and form a stable connection. Through the close fit of the protrusion 1211 and the groove 1212, the cutout 121 of the guide sleeve 120 realizes reliable splicing connection. When the guide sleeve 120 needs to be replaced or repaired, the protrusion 1211 can be pulled out of the groove 1212 to easily open the cutout 121 of the guide sleeve 120, and the guide sleeve 120 can be removed from the guide rod 110, which is convenient for installation and maintenance. When the guide sleeve 120 is sleeved on the guide rod 110, the protrusion 1211 is embedded in the groove 1212 and is extruded, so that the two side edges of the cutout 121 are spliced and connected, and a stable circular structure is formed. Moreover, the matching structure of the protrusion 1211 and the groove 1212 has a certain elasticity and adjustability. When the guide sleeve 120 changes in size due to temperature changes, wear and other reasons, the gap between the protrusion 1211 and the groove 1212 can act as a buffer, and the guide sleeve 120 can still maintain good connection and sliding performance through appropriate adjustment, so that the guide assembly 100 can stably operate in different working environments and working conditions, and the application range is widened.

[0042] For example, the buckle connection form can be:

[0043] The elastic buckle is provided on one side edge of the cutout 121, and the shape of the elastic buckle can be hook-shaped, and the other side edge of the cutout 121 is provided with a corresponding clamping groove. When the guide sleeve 120 is installed, the elastic buckle on one side edge of the cutout 121 is pressed into the clamping groove on the other side edge of the cutout 121, so that the guide sleeve 120 is quickly connected at the cutout 121. The above is only exemplary and is not limited. The structure design of the cutout 121 and the splicing connection thereof on the guide sleeve 120 enables the guide sleeve 120 to be quickly disassembled or installed on the guide rod 110.

[0044] In some embodiments, as Figure 3As shown, the number of cutouts 121 is two, and the two cutouts 121 divide the guide sleeve 120 into two. Specifically, the two cutouts 121 are symmetrically arranged about the axis of the guide sleeve 120, and based on the two cutouts 121, the guide sleeve 120 is divided into a first part and a second part, and by butting the first part and the second part, the complete guide sleeve 120 can be assembled; and by disassembling the first part and the second part, the guide sleeve 120 can be disassembled. In this embodiment, the guide sleeve 120 is designed with double cutouts 121, which is simpler to disassemble than a single cutout 121 design, and does not require the guide sleeve 120 to be bent, so the guide sleeve 120 will not deform and the like, and the structural precision of the guide sleeve 120 can be ensured.

[0045] In some embodiments, as Figure 2 As shown, the connecting seat 130 includes a first sub-seat 131 and a second sub-seat 132, the first sub-seat 131 is provided with a first inner cavity, and the second sub-seat 132 is provided with a second inner cavity, and the first inner cavity and the second inner cavity together constitute a receiving cavity 130Q for accommodating the guide sleeve 120.

[0046] The second sub-seat 132 is detachably connected with the first sub-seat 131 to fix or remove the guide sleeve 120.

[0047] The first inner cavity of the first sub-seat 131 has a specific shape and size, and tightly fits with a part of the guide sleeve 120, providing stable support and positioning for the guide sleeve 120. The inner wall of the first inner cavity is wear-resistant and smooth, which can reduce the friction resistance of the guide sleeve 120 during installation and use, and ensure that the guide sleeve 120 will not be damaged due to friction with the inner wall during long-term use.

[0048] The second inner cavity of the second sub-seat 132 has substantially the same shape and size as the first inner cavity, and when the first sub-seat 131 and the second sub-seat 132 are combined together, the first inner cavity and the second inner cavity together constitute a complete receiving cavity 130Q, which has the same shape and size as the guide sleeve 120 and can accurately accommodate the guide sleeve 120, preventing the guide sleeve 120 from shifting or shaking during work, thereby ensuring the accuracy and reliability of the guide.

[0049] And, the second seat 132 and the first seat 131 are detachably connected, which provides great convenience for fixing and taking out the guide sleeve 120. For example, the first seat 131 and the second seat 132 are detachably connected by means of screw connection, buckle connection or the like. When the guide sleeve 120 needs to be installed, the guide sleeve 120 is first placed in the first inner cavity of the first seat 131, and then the second seat 132 is tightly combined with the first seat 131 by a predetermined connection manner, so that the guide sleeve 120 is firmly fixed in the containing cavity 130Q composed of the first inner cavity and the second inner cavity. In the use process of the guide assembly 100, the guide sleeve 120 can stably play its guiding and supporting role, and ensure the smooth operation of the related components.

[0050] When the guide sleeve 120 needs to be maintained, replaced or overhauled, the operator only needs to follow the predetermined disassembly steps to release the connection between the second seat 132 and the first seat 131, so that the guide sleeve 120 can be easily taken out from the containing cavity 130Q for corresponding operation. The detachable design of the seat 130 greatly shortens the disassembly time, reduces the maintenance cost and improves the production efficiency.

[0051] In some embodiments, as shown in Figure 2 The threaded connection structure can be one or more, and the present embodiment does not limit this. The first seat 131 and the second seat 132 are connected or separated by the threaded connection structure, which has the advantages of simple operation, reliable connection, low cost and the like, and can effectively meet the needs in the actual production and use process, and provide a strong guarantee for the efficient operation and convenient maintenance of the whole device.

[0052] In some embodiments, one side of the first seat 131 and the second seat 132 is provided with a threaded connection structure, and the other side is provided with a hinged structure, and the first seat 131 and the second seat 132 can be flipped by the hinged structure.

[0053] The hinge structure can be composed of a pin shaft and shaft sleeves respectively located on the first sub-seat 131 and the second sub-seat 132. The pin shaft passes through the shaft sleeves, so that the first sub-seat 131 and the second sub-seat 132 can perform relative flipping motion around the pin shaft. The design of the hinge structure allows the first sub-seat 131 and the second sub-seat 132 to perform relative flipping within a certain angle range. For example, in some application scenarios, a flipping angle range of 0 to 90 degrees can be achieved, which provides convenience for disassembly and assembly of the connecting seat 130 and operation in special cases.

[0054] When it is necessary to maintain or replace the guide sleeve 120 or to check the inside of the connecting seat 130, the threaded connection structure is first loosened using a tool, and then the second sub-seat 132 is flipped open relative to the first sub-seat 131 through the hinge structure, so that the guide sleeve 120 can be conveniently taken out or the inside of the connecting seat 130 can be operated. During the entire process, the presence of the hinge structure makes the operation more flexible, without the need to completely disassemble the connecting seat 130, saving operation time and labor cost, and improving the maintenance efficiency of the equipment.

[0055] In some embodiments, as shown in Figure 2 A limiting protrusion 130T is arranged on one side of the accommodating cavity 130Q, which is used to limit the guide sleeve 120 located in the accommodating cavity 130Q; wherein the limiting protrusion 130T can be a partial ring structure, and is arranged to protrude and extend towards the center of the accommodating cavity 130Q.

[0056] The guide assembly further includes a limiting plate 140 located on the other side of the accommodating cavity 130Q, which is detachably connected with the connecting seat 130 through a fastener 10, and is provided with a limiting hole through which the guide rod passes.

[0057] The installation process of the guide sleeve 120 is as follows: the guide sleeve 120 is installed into the accommodating cavity 130Q from the side where the limiting plate 140 is located, so that one side of the guide sleeve 120 is in contact with the limiting protrusion 130T in the accommodating cavity 130Q. At this time, the limiting protrusion 130T plays a preliminary positioning role, limiting the movement of the guide sleeve 120 in this direction. Then the limiting plate 140 is installed on the connecting seat 130 through the fastener 10, so that the limiting plate 140 tightly fits the other side of the guide sleeve 120, further fixing the position of the guide sleeve 120, ensuring that the guide sleeve 120 will not be loose or displaced in the accommodating cavity 130Q, thereby realizing the installation of the guide sleeve 120.

[0058] When the guide sleeve 120 needs to be maintained or replaced, only need to disassemble the fastener 10 on the limiting plate 140, remove the limiting plate 140, and then the guide sleeve 120 can be easily taken out from the containing cavity 130Q. During the whole process, due to the reasonable design of the limiting protrusion 130T and the limiting plate 140, the operation is simple and fast, without complex tools and cumbersome steps, which improves the maintainability of the equipment.

[0059] Optionally, the number of fasteners 10 is multiple, and the multiple fasteners 10 are arranged at intervals along the circumferential side of the containing cavity 130Q. The uniform circumferential arrangement of the multiple fasteners 10 can make the limiting plate 140 bear force uniformly on the connecting seat 130, preventing the limiting plate 140 from deforming or the connection from loosening due to excessive local force. For example, taking the limiting plate 140 with a rectangular shape as an example, fasteners 10 can be arranged at the positions of the four corners of the limiting plate 140, ensuring that the limiting plate 140 can be tightly connected with the connecting seat 130 in all directions. The number of fasteners 10 can be set according to actual needs, which is not limited herein.

[0060] In some embodiments, as shown in Figure 1 and Figure 2 , the same side of the first sub-seat 131 and the second sub-seat 132 is provided with a containing groove 130C matched with the limiting plate 140, and the limiting plate 140 is contained in the containing groove 130C. The shape of the containing groove 130C matches the shape of the limiting plate 140, for example, the limiting plate 140 is rectangular, and the containing groove 130C is a rectangular groove. When installing, the limiting plate 140 is put into the containing groove 130C along the opening direction of the containing groove 130C, the surface of the limiting plate 140 is basically flush with the outer surface of the connecting seat 130, and then the limiting plate 140 is fastened to the connecting seat 130 by the fastener 10. The containing groove 130C provides an accurate installation position for the limiting plate 140, so that the limiting plate 140 can be quickly and accurately positioned during installation. Moreover, the design of the containing groove 130C makes the limiting plate 140 reasonably embedded in the side of the connecting seat 130, avoiding the additional occupation of space outside the connecting seat 130 by the limiting plate 140, which helps to improve the compactness of the structure.

[0061] In some embodiments, multiple guide sleeves 120 are provided, and the connecting seat 130 is correspondingly provided. According to the structural design of the multiple layer plates 200 in the battery formation clamp, multiple guide sleeves 120 and connecting seats 130 can be correspondingly provided in the guide assembly 100 to be connected with the multiple layer plates 200, so as to realize the movement guidance of the multiple layer plates 200. The specific number of guide sleeves 120 and connecting seats 130 can refer to the number of layer plates 200 in the battery formation clamp, which is not limited in the present embodiment.

[0062] Referring to Figure 4 , Figure 4A structure schematic view of the battery formation fixture in one embodiment of the present application is shown in the figure.

[0063] The present application also provides a battery formation fixture, as shown in the figure. Figure 4 The specific structure of the guide assembly 100 is referred to the above embodiments, since the battery formation fixture adopts all the technical solutions of the above embodiments, it has at least all the technical effects brought by the technical solutions of the above embodiments, which will not be repeated here. In the battery formation fixture, the number of the layer plates 200 is multiple, the number of the guide sleeves 120 and the connecting seats 130 in the guide assembly 100 can be correspondingly configured to be multiple, and are arranged on the guide rods 110, each connecting seat 130 is connected with one layer plate 200. In addition, the guide assembly 100 can be arranged in two, and the two guide assemblies 100 are respectively arranged on the opposite sides of the layer plate 200 to be connected with the layer plate 200.

[0064] The above is only some or preferred embodiments of the present application, neither the text nor the drawings can limit the scope of protection of the present application, any equivalent structural transformation using the content of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the scope of protection of the present application.
