The appearances of the phrase in various places in the specification are not necessarily all referring to the same example, nor are they necessarily mutually exclusive or alternative examples to one another.

[0059] In the description of the application, it should be explained that, unless otherwise explicitly specified and limited, the terms “mount”, “connect”, “connection”, “attach” should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, or integrally connected, it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal communication of two elements.

In addition, the character “ / ” in this application generally represents that the front and rear associated objects have an “or” relationship.

[0061] In the embodiments of the application, the same reference signs represent the same parts, and for the sake of brevity, the detailed description of the same parts is omitted in different embodiments. It should be understood that the thickness, length and width of various components in the embodiments of the application shown in the drawings, as well as the overall thickness, length and width of the integrated device, are only exemplary and should not constitute any limitation on the application.

[0062] “Multiple” appearing in this application means more than two (including two).

[0063] In the related art, the production device includes a moving pair mechanism, the moving pair mechanism includes a guide rail and a sliding block, and a ball is arranged between the guide rail and the sliding block to enable the sliding block to slide along the guide rail. However, the sliding block is prone to extruding the ball during movement, which causes the ball to splash, and the splashed ball is extremely easy to injure the production personnel or damage the product, and the production reliability is poor.

[0064] Based on the above consideration, in order to solve the technical problem that the ball splashes and injures the production personnel or damages the product. The application provides a moving pair mechanism, comprising: a guide portion and a moving portion, the guide portion extends along a first direction, the moving portion is arranged on the guide portion, the moving portion is movable relative to the guide portion along the first direction, a ball is arranged between the guide portion and the moving portion, and the ball abuts against the guide portion and the moving portion; a protective cover, the protective cover is arranged on the moving portion, and the protective cover is configured to limit the ball in the protective cover in the case that the ball moves out from between the guide portion and the moving portion.

[0065] In the moving sub-mechanism, by arranging the protective cover, in the case that the ball moves out from between the guide part and the moving part, the ball can be limited in the protective cover, the risk of product damage caused by the ball falling to the product is reduced, the risk of injury caused by the ball splashing is reduced, and the production reliability is improved.

[0066] Reference will be made to the accompanying drawings Figures 1-4 The moving sub-mechanism 100 according to the embodiments of the present application is described.

[0067] Reference Figures 1-4 As shown in the figure, the moving sub-mechanism 100 according to the embodiments of the present application comprises: a guide part 1 and a moving part 2, the guide part 1 extends along a first direction, the moving part 2 is arranged on the guide part 1, the moving part 2 is movable relative to the guide part 1 along the first direction, a ball 3 is arranged between the guide part 1 and the moving part 2, and the ball 3 abuts against both the guide part 1 and the moving part 2; and a protective cover 4, the protective cover 4 is arranged on the moving part 2, and the protective cover 4 is configured to limit the ball 3 in the protective cover 4 in the case that the ball 3 moves out from between the guide part 1 and the moving part 2.

[0068] It should be explained that the moving sub-mechanism 100 according to the embodiments of the present application can be used as a mechanism for supporting and guiding a moving part to make reciprocating linear motion in a given direction (for example, the first direction in the present application). The guide part 1 can be understood as a track (i.e. the guide rail in the above embodiments) providing linear motion, and the moving part 2 moves on the guide part 1 to realize the motion.

[0069] Wherein, along the first direction, i.e. Figure 1 The X direction shown in the figure, the guide part 1 extends, and the moving part 2 is movably arranged on the guide part 1. Specifically, along the first direction, the moving part 2 is movable relative to the guide part 1. A ball 3 is arranged between the guide part 1 and the moving part 2, and the number of balls 3 can be one, two, four or more. The ball 3 is arranged in abutment with both the guide part 1 and the moving part 2, so that the ball 3 is arranged between the guide part 1 and the moving part 2, thereby enabling the moving part 2 to smoothly slide along the guide part 1. By arranging the ball 3 between the guide part 1 and the moving part 2, the cooperation of the guide part 1 and the moving part 2 can be adjusted to rolling cooperation through the ball 3, thereby reducing the wear rate of the guide part 1 and the moving part 2, improving the service life of the moving sub-mechanism 100, and by arranging the ball 3 between the guide part 1 and the moving part 2, the movement of the moving part 2 is smooth and smooth, thereby improving the use stability of the moving sub-mechanism 100.

[0070] As some embodiments of the present application, the moving part 2 has a first groove 22 on the surface facing the guide part 1, the first groove 22 is recessed towards the moving part 2, the guide part 1 has a second groove 11 on the surface facing the moving part 2, the second groove 11 is recessed towards the guide part 1, the number of the first grooves 22 is the same as that of the second grooves 11, and each of the partial structures of the balls 3 is accommodated in the first groove 22 and the second groove 11.

[0071] It should be noted that during the movement of the moving part 2 along the first direction relative to the guide part 1, the ball 3 may move out (or can be understood as splash out) from between the guide part 1 and the moving part 2. The ball 3 that moves out may be the entire structure of the ball 3, or the ball 3 that moves out may be a partial structure of the ball 3, such as a fragment of the ball 3. The present application is described by taking the example that the entire structure of the ball 3 moves out from between the guide part 1 and the moving part 2. The reasons for the ball 3 moving out from between the guide part 1 and the moving part 2 are various, for example, the ball 3 moves out from between the guide part 1 and the moving part 2 due to design or installation, etc. Specifically, if the corresponding multiple reservation (design) is not reached during the selection process or if the flatness and parallelism are not adjusted or are not adjusted well after the installation of the pair of guide part 1 and moving part 2, the ball 3 may be unevenly stressed, causing the ball 3 on one side to be excessively stressed or even excessively worn, thereby causing the ball 3 to move out from between the guide part 1 and the moving part 2. The ball 3 that splashes out from between the guide part 1 and the moving part 2 is easy to hurt the production personnel or damage the product, and the production reliability is poor.

[0072] The protective cover 4 is arranged on the moving part 2, and the protective cover 4 is configured to limit the ball 3 in the protective cover 4 when the ball 3 moves out from between the guide part 1 and the moving part 2. As some embodiments of the present application, the protective cover 4 is arranged on the moving part 2, the protective cover 4 is connected to the moving part 2 and can move with the moving part 2. When the ball 3 moves out from between the guide part 1 and the moving part 2, since the protective cover 4 always moves with the moving part 2, the protective cover 4 can limit the ball 3 in the protective cover 4, thereby reducing the risk of the ball 3 falling to the product and causing damage to the product. As some embodiments of the present application, the protective cover 4 can also be arranged on the entire travel route of the moving part 2, the protective cover 4 does not move with the moving part 2, the protective cover 4 is provided with an avoiding hole 46 to avoid the components connected to the moving part 2, and the area size of the avoiding hole 46 can be smaller than the diameter size of the ball 3. When the ball 3 moves out from between the guide part 1 and the moving part 2, since the protective cover 4 is arranged on the moving part 2 and on the entire travel route of the moving part 2, the protective cover 4 can limit the ball 3 in the protective cover 4, thereby reducing the risk of the ball 3 falling to the product and causing damage to the product.

[0073] As some embodiments of the present application, the protective cover 4 can be configured as a flexible member, and the flexible member can be made of rubber, resin or the like. By configuring the protective cover 4 as a flexible member, the probability of the protective cover 4 being broken due to impact can be reduced, the use reliability and service life of the protective cover 4 can be improved, and the noise risk of the moving pair mechanism 100 can be reduced.

[0074] Specifically, the guide portion 1 is arranged to extend along the first direction, the ball 3 is arranged between the moving portion 2 and the guide portion 1, and the ball 3 abuts against both the guide portion 1 and the moving portion 2, so that the moving portion 2 is movably arranged on the guide portion 1, and further, the moving portion 2 is movable relative to the guide portion 1 along the first direction. The protective cover 4 is arranged on the moving portion 2, and when the ball 3 moves out from between the guide portion 1 and the moving portion 2, the protective cover 4 can limit the ball 3 in the protective cover 4.

[0075] In the above technical solution, by arranging the protective cover 4, the ball 3 can be limited in the protective cover 4, the risk of the ball 3 falling to the product and causing damage to the product can be reduced, the risk of the ball 3 splashing and causing injury can be reduced, and thus the production reliability can be improved.

[0076] According to some embodiments of the present application, referring to FIG. 1, the moving pair mechanism 100 further comprises a suction structure (not shown in the figure) arranged in the protective cover 4, and the suction structure is configured to suck the ball 3 when the ball 3 moves out from between the guide portion 1 and the moving portion 2. Figure 2

[0077] As some embodiments of the present application, the suction structure can be configured as a permanent magnet, the permanent magnet has magnetism, the ball 3 can be a steel ball or an iron ball, and when the ball 3 moves out from between the guide portion 1 and the moving portion 2, the permanent magnet can suck the ball 3, so as to fix the ball 3 at a certain position, facilitating the workers to clean up quickly. As some embodiments of the present application, the suction structure can be configured as an electromagnet, by energizing the electromagnet, the electromagnet can have magnetism, and when the ball 3 moves out from between the guide portion 1 and the moving portion 2, the electromagnet can suck the ball 3, so as to fix the ball 3 at a certain position, facilitating the workers to clean up quickly.

[0078] As some embodiments of the present application, the suction structure can be configured as a rubidium magnet, which has the advantages of high magnetic permeability, stable magnetic field, low price, relatively easy to manufacture, long service life, etc. By configuring the suction structure as a rubidium magnet, the production cost of the moving pair mechanism 100 can be reduced, the service life of the moving pair mechanism 100 can be prolonged, the ball 3 can be stably fixed at a certain position, and the workers can clean up quickly.​

[0079] In the above technical solution, by setting the adsorption structure in the protective cover 4, the ball 3 moving out from between the guide part 1 and the moving part 2 can be adsorbed by the adsorption structure, so that the splashed ball 3 can be stably fixed in a certain position (i.e. the position where the adsorption structure is arranged), reducing the risk of product damage caused by the falling of the ball 3 to the product, reducing the risk of injury caused by the splashing of the ball 3, improving production reliability, and facilitating quick cleaning by the staff.

[0080] According to some embodiments of the present application, referring to Figure 2 The adsorption structure is fixedly arranged in the protective cover 4.

The inner surface of the protective cover 4 can be understood as the surface of the protective cover 4 facing the moving part 2. The adsorption structure is fixed to the mounting structure 41. As some embodiments of this application, the mounting structure 41 may have a mounting groove. At least a portion of the adsorption structure can be received in the mounting groove and fixed within it. For example, the mounting groove has a mating protrusion, and the adsorption structure has a mating groove that mates with the mating protrusion. By engaging the mating protrusion with the mating groove, the adsorption structure can be fixed to the mounting groove.

[0085] As some embodiments of this application, the mounting structure 41 may have a mounting hole 411, and the adsorption structure may be fixed in the mounting hole 411. For example, the mounting hole 411 may be a through hole or a groove structure. At least a portion of the adsorption structure may be provided in and fixed in the mounting hole 411. By providing the mounting structure 41 on the inner surface of the protective cover 4 and fixing the adsorption structure to the mounting structure 41, the adsorption structure can be easily fixed, reducing the installation difficulty of the adsorption structure and improving the installation efficiency of the adsorption structure. Moreover, installing the adsorption structure through the mounting structure 41 helps to improve the installation firmness of the adsorption structure and reduce the risk of the adsorption structure falling off.

[0086] In the above technical solution, by providing an installation structure 41 on the inner surface of the protective cover 4 and fixing the adsorption structure to the installation structure 41, the adsorption structure can be easily fixed, the installation difficulty of the adsorption structure can be reduced, and the installation efficiency of the adsorption structure can be improved. Moreover, installing the adsorption structure through the installation structure 41 helps to improve the installation firmness of the adsorption structure and reduce the risk of the adsorption structure falling off.

[0087] According to some embodiments of this application, refer to Figure 2 As shown, the mounting structure 41 defines the mounting hole 411, and the adsorption structure is fixed in the mounting hole 411.

[0088] The mounting hole 411 can be a through hole, i.e., the mounting hole 411 penetrates the mounting structure 41, or the mounting hole 411 can be a slot structure, and at least part of the adsorption structure can be arranged in the mounting hole 411, for example, part of the adsorption structure can be arranged in the mounting hole 411, or the entire adsorption structure is arranged in the mounting hole 411, and at least part of the adsorption structure can be fixedly arranged in the mounting hole 411. As some embodiments of the present application, at least part of the adsorption structure can be interference fit with the mounting hole 411 to fix the adsorption structure to the mounting hole 411, or at least part of the adsorption structure can be adhesively fit with the mounting hole 411 to fix the adsorption structure to the mounting hole 411. By defining the mounting hole 411 by the mounting structure 41 and fixing the adsorption structure to the mounting hole 411, the adsorption structure can be conveniently fixed to the mounting structure 41, reducing the installation difficulty of the adsorption structure and improving the installation efficiency of the adsorption structure. Moreover, by installing the adsorption structure through the mounting hole 411, the installation firmness of the adsorption structure can be significantly improved, and the risk of the adsorption structure falling off can be effectively reduced.

[0089] In the above technical solution, by defining the mounting hole 411 by the mounting structure 41 and fixing the adsorption structure to the mounting hole 411, the adsorption structure can be conveniently fixed to the mounting structure 41, reducing the installation difficulty of the adsorption structure and improving the installation efficiency of the adsorption structure. Moreover, by installing the adsorption structure through the mounting hole 411, the installation firmness of the adsorption structure can be significantly improved, and the risk of the adsorption structure falling off can be effectively reduced.

[0090] According to some embodiments of the present application, referring to FIG. 1, Figure 2 As shown in FIG. 1, the mounting structure 41 and the adsorption structure are both multiple, and the multiple adsorption structures and the multiple mounting structures 41 are one-to-one corresponding.

[0091] The number of the mounting structure 41 is multiple, for example, the number of the mounting structure 41 can be but is not limited to two, three, four, etc., and the number of the adsorption structure is multiple, for example, the number of the adsorption structure can be but is not limited to two, three, four, etc., and the multiple adsorption structures and the multiple mounting structures 41 are one-to-one corresponding. As some embodiments of the present application, the number of the mounting structure 41 is four, and the number of the adsorption structure is four. Along the first direction, two mounting structures 41 are located on one side of the moving part 2, and the other two mounting structures 41 are located on the other side of the moving part 2. The two mounting structures 41 located on the same side are spaced apart, and the four adsorption structures are respectively fixed to the corresponding mounting structures 41.

[0092] By setting the mounting structure 41 and the adsorption structure as multiple, and setting the multiple adsorption structures and the multiple mounting structures 41 one by one, the ball 3 moving out from between the guide part 1 and the moving part 2 can be effectively adsorbed by the adsorption structure, the risk that the splashed ball 3 cannot be reliably adsorbed due to too many splashed balls 3 is reduced, the risk of product damage caused by the ball 3 falling to the product is more favorably reduced, the risk of injury caused by the ball 3 splashing is more favorably reduced, and the production reliability is more favorably improved.

[0093] In the above technical solution, by setting the mounting structure 41 and the adsorption structure as multiple, and setting the multiple adsorption structures and the multiple mounting structures 41 one by one, the ball 3 moving out from between the guide part 1 and the moving part 2 can be effectively adsorbed by the adsorption structure, the risk that the splashed ball 3 cannot be reliably adsorbed due to too many splashed balls 3 is reduced, the risk of product damage caused by the ball 3 falling to the product is more favorably reduced, the risk of injury caused by the ball 3 splashing is more favorably reduced, and the production reliability is more favorably improved.

[0094] According to some embodiments of the present application, referring to Figure 2 As shown in the figure, along the first direction, at least one side of the moving part 2 is provided with an adsorption structure, and the adsorption structure is opposite and spaced apart from the moving part 2.

[0095] As some embodiments of the present application, along the first direction, one side of the moving part 2 is provided with an adsorption structure, or along the first direction, both sides of the moving part 2 are provided with an adsorption structure. The adsorption structure is opposite to the moving part 2, and the adsorption structure is spaced apart from the moving part 2.

[0096] As some embodiments of the present application, the number of adsorption structures is four, along the first direction, both sides of the moving part 2 are provided with an adsorption structure, specifically, along the first direction, one side of the moving part 2 is provided with two adsorption structures, and the other side of the moving part 2 is provided with two adsorption structures, and the four adsorption structures are opposite and spaced apart from the moving part 2. Further, along the first direction, the adsorption structure is correspondingly arranged between the moving part 2 and the guide part 1. By providing at least one side of the moving part 2 with an adsorption structure, the setting position of the adsorption structure can be reasonable, which is convenient for adsorbing the ball 3 moving out from between the guide part 1 and the moving part 2, further reduces the risk of product damage caused by the ball 3 falling to the product, further reduces the risk of injury caused by the ball 3 splashing, further improves the production reliability, and by setting the adsorption structure opposite and spaced apart from the moving part 2, the risk of interference between the adsorption structure and the moving part 2 is reduced, which is conducive to improving the use reliability of the moving pair mechanism 100.

[0097] In the technical solution, the at least one side of the moving part 2 is provided with the adsorption structure, the position of the adsorption structure is reasonable, the adsorption structure can adsorb the balls 3 moving out of the guide part 1 and the moving part 2, the risk of the balls 3 falling to the product and causing damage to the product is further reduced, the risk of the balls 3 splashing and causing injury is further reduced, the production reliability is improved, and the adsorption structure and the moving part 2 are arranged relatively and spaced apart, the interference risk of the adsorption structure and the moving part 2 is reduced, and the use reliability of the moving pair mechanism 100 is improved.

[0098] According to some embodiments of the present application, referring to Figure 1 The protective cover 4 is configured as a transparent piece.

[0099] The protective cover 4 is configured as a transparent piece, that is, the situation inside the protective cover 4 can be observed from the outside of the protective cover 4. Specifically, the protective cover 4 can be made of resin, acrylic or other materials. The moving part 2, the adsorption structure and the balls 3 inside the protective cover 4 can be observed from the outside of the protective cover 4, so that the staff can intuitively and quickly check the situation inside the protective cover 4 and respond in time. As an example, when the balls 3 fall, the staff can discover the falling of the balls 3 in time, so as to respond in time, for example, reinstall the balls 3 between the guide part 1 and the moving part 2, or install new balls 3 between the guide part 1 and the moving part 2, reduce the risk of the balls 3 continuously falling and causing the guide part 1 and the moving part 2 to jam, and improve the working stability and reliability of the moving pair mechanism 100.

[0100] In the technical solution, the protective cover 4 is configured as a transparent piece, which can help the staff to intuitively and quickly check the situation inside the protective cover 4 from the outside of the protective cover 4, so as to quickly take measures when the moving pair mechanism 100 has problems, reduce the risk of the moving pair mechanism 100 having problems due to the balls 3 falling, and further reduce the risk of production problems.

[0101] According to some embodiments of the present application, referring to Figure 1 The protective cover 4 is fixed to the moving part 2, and the moving part 2 moves synchronously with the protective cover 4.

[0102] The protective cover 4 is fixed to the moving part 2. According to some embodiments of the present application, the protective cover 4 is fixed to the moving part 2 by screw connection. According to some embodiments of the present application, the protective cover 4 is fixed to the moving part 2 by clamping or bonding. When the moving part 2 moves, the protective cover 4 moves synchronously. That is, the protective cover 4 can move synchronously with the moving part 2. The protective cover 4 can limit the ball 3 in the protective cover 4, reduce the risk of the ball 3 falling to the product and causing damage to the product, and facilitate reducing the size of the protective cover 4 and reducing the production cost of the protective cover 4. In addition, it can also reduce the probability of affecting production due to the large size of the protective cover 4.

[0103] In the above technical solution, the protective cover 4 is fixed to the moving part 2, and when the moving part 2 moves, the protective cover 4 moves synchronously. The protective cover 4 can limit the ball 3 in the protective cover 4, reduce the risk of the ball 3 falling to the product and causing damage to the product, and facilitate reducing the size of the protective cover 4 and reducing the production cost of the protective cover 4. In addition, it can also reduce the probability of affecting production due to the large size of the protective cover 4.

[0104] According to some embodiments of the present application, referring to Figure 2 The protective cover 4 defines an installation space 42, and at least part of the moving part 2 is located in the installation space 42. The guide part 1 penetrates the protective cover 4.

[0105] The protective cover 4 can define an installation space 42, which can provide an assembly position for the moving part 2, so that at least part of the moving part 2 is located in the installation space 42. For example, part of the moving part 2 is located in the installation space 42, or all structures of the moving part 2 are located in the installation space 42. Such arrangement can make the moving part 2 work reliably in the installation space 42, reduce the interference of the external environment on the moving part 2, and thus improve the service life of the moving part 2. In the first direction, the protective cover 4 has opposite two side walls, and the opposite two side walls of the protective cover 4 in the first direction each have a avoiding through hole 49. The shape of the avoiding through hole 49 is adapted to the cross-sectional shape of the guide part 1, so that the guide part 1 can penetrate the protective cover 4 in the first direction. This is conducive to the smooth movement of the moving part 2 and the protective cover 4 relative to the guide part 1 in the first direction. In addition, the gap size between the protective cover 4 and the guide part 1 is smaller than the diameter size of the ball 3, which reduces the risk of the ball 3 flying out from the gap between the protective cover 4 and the guide part 1, and further improves the working reliability of the moving pair mechanism 100. The guide part 1 penetrates the protective cover 4, which can effectively reduce the size of the protective cover 4, thereby reducing the size of the moving pair mechanism 100 and the production cost of the protective cover 4, and facilitating the flexible arrangement of the moving pair mechanism 100.

[0106] In the above technical solution, by defining the mounting space 42 by the protective cover 4, at least part of the moving part 2 is located in the mounting space 42, and the guide part 1 is provided in the protective cover 4, which can make the moving part 2 work reliably in the mounting space 42, reduce the interference of the external environment on the moving part 2, and thus improve the service life of the moving part 2. It is also beneficial for the moving part 2 and the protective cover 4 to move smoothly along the first direction relative to the guide part 1, and the gap size between the protective cover 4 and the guide part 1 is smaller than the diameter size of the ball 3, which reduces the risk of the ball 3 flying out of the gap between the protective cover 4 and the guide part 1, thereby further improving the working reliability of the moving pair mechanism 100. The guide part 1 is provided in the protective cover 4, which can effectively reduce the volume of the protective cover 4, thereby reducing the volume of the moving pair mechanism 100 and the production cost of the protective cover 4, and facilitating the flexible arrangement of the moving pair mechanism 100.

[0107] According to some embodiments of the present application, referring to Figures 1-3 As shown in the figure, the protective cover 4 has a first wall part 43, a second wall part 44 and a third wall part 45. Along the second direction, the first wall part 43 is located on the side of the moving part 2 away from the guide part 1, the second wall part 44 is located on the side of the moving part 2 away from the first wall part 43, and the third wall part 45 is connected between the first wall part 43 and the second wall part 44, and the third wall part 45 is arranged around the moving part 2 along the circumferential edge of the first wall part 43, so that the first wall part 43, the second wall part 44 and the third wall part 45 jointly define the mounting space 42, and the first direction and the second direction are perpendicular.

[0108] Among them, along the second direction, that is, the Y direction in Figure 1 , the first wall part 43 is located on the side of the moving part 2 away from the guide part 1, and the second wall part 44 is located on the side of the moving part 2 away from the first wall part 43, for example: the first wall part 43 and the second wall part 44 are oppositely arranged along the second direction, and the first wall part 43 and the second wall part 44 are arranged on both sides of the moving part 2 along the second direction. The third wall part 45 is connected between the first wall part 43 and the second wall part 44, for example: the third wall part 45 can be integrally formed with the first wall part 43 and the second wall part 44, and the third wall part 45 can be connected with the first wall part 43 and the second wall part 44. The third wall part 45 is arranged around the moving part 2 along the circumferential edge of the first wall part 43, so that the first wall part 43, the second wall part 44 and the third wall part 45 jointly define the mounting space 42. Such arrangement can make the design of the mounting space 42 reasonable, which is beneficial for the first wall part 43, the second wall part 44 and the third wall part 45 to limit the ball 3 on both sides of the second direction and around the moving part 2, reduce the risk of product damage caused by the ball 3 falling to the product, and also reduce the risk of injury caused by the ball 3 splashing, thereby improving the production reliability. The first direction and the second direction are perpendicular, that is, the X direction and the Y direction are perpendicular.

[0109] In the above technical solution, along the second direction, by positioning the first wall portion 43 on the side of the moving part 2 away from the guide portion 1, the second wall portion 44 on the side of the moving part 2 away from the first wall portion 43, and the third wall portion 45 connecting the first wall portion 43 and the second wall portion 44, and the third wall portion 45 surrounding the moving part 2 along the circumferential edge of the first wall portion 43, the first wall portion 43, the second wall portion 44, and the third wall portion 45 together define the installation space 42. This allows for a reasonable design of the installation space 42, which is beneficial for the first wall portion 43, the second wall portion 44, and the third wall portion 45 to limit the ball bearing 3 on both sides of the second direction and around the moving part 2, respectively. This reduces the risk of the ball bearing 3 falling onto the product and causing product damage, and also reduces the risk of the ball bearing 3 splashing and causing injury, thereby improving production reliability.

[0110] Understandably, during battery production, this reduces the risk of ball bearing 3 falling into the battery and puncturing the blue film of the cell, thereby reducing the risk of battery insulation failure, failure to pass insulation tests, or even battery short circuits, smoke, and fire, which helps improve battery production reliability.

[0111] According to some embodiments of this application, refer to Figures 1-3 As shown, the third wall portion 45 has a first sub-wall portion 451 and a second sub-wall portion 452. The first sub-wall portion 451 and the second sub-wall portion 452 are opposite to each other and spaced apart along a first direction. The first sub-wall portion 451 and the second sub-wall portion 452 are respectively formed with a first through hole 491 and a second through hole 492. The guide portion 1 passes through the first through hole 491 and the second through hole 492.

[0112] In the first direction, the first sub-wall portion 451 and the second sub-wall portion 452 are arranged opposite to each other and spaced apart, so that the moving part 2 can be assembled between the first sub-wall portion 451 and the second sub-wall portion 452. The first sub-wall portion 451 and the second sub-wall portion 452 are respectively formed with a first through hole 491 and a second through hole 492. The first through hole 491 and the second through hole 492 are the clearance through holes 49 in the above embodiment. The shapes of the first through hole 491 and the second through hole 492 are adapted to the cross-sectional shape of the guide portion 1, so that the guide portion 1 can pass through the first through hole 491 and the second through hole 492. 2. This allows the guide part 1 to pass through the protective cover 4, which facilitates the smooth movement of the moving part 2 and the protective cover 4 relative to the guide part 1 along the first direction. It also effectively reduces the volume of the protective cover 4, thereby reducing the volume of the moving sub-mechanism 100 and the production cost of the protective cover 4. This facilitates the flexible arrangement of the moving sub-mechanism 100. Furthermore, it makes the gap between the first sub-wall part 451 and the guide part 1, and the gap between the second sub-wall part 452 and the guide part 1, smaller than the diameter of the ball 3, reducing the risk of the ball 3 flying out from the gap between the protective cover 4 and the guide part 1, thereby further improving the working reliability of the moving sub-mechanism 100.

[0113] In the above technical solution, by relatively and spacedly arranging the first sub-wall part 451 and the second sub-wall part 452 along the first direction, the first sub-wall part 451 and the second sub-wall part 452 are respectively formed with the first through hole 491 and the second through hole 492, and the guide part 1 is arranged through the first through hole 491 and the second through hole 492, so that the guide part 1 can be arranged through the protective cover 4, which is beneficial to the smooth movement of the moving part 2 and the protective cover 4 relative to the guide part 1 along the first direction, and can effectively reduce the volume of the protective cover 4, thereby reducing the volume of the moving sub-mechanism 100 and the production cost of the protective cover 4, and is also beneficial to the flexible arrangement of the moving sub-mechanism 100. In addition, the gap between the first sub-wall part 451 and the guide part 1 and the gap between the second sub-wall part 452 and the guide part 1 are both smaller than the diameter of the ball 3, which reduces the risk of the ball 3 flying out from the gap between the protective cover 4 and the guide part 1, thereby further improving the working reliability of the moving sub-mechanism 100.

[0114] According to some embodiments of the present application, referring to Figures 1-3 As shown in FIG. 4, the second wall part 44 is formed with a third through hole 441 extending along the first direction, the third through hole 441 and the mounting space 42 are in communication, and the two ends of the third through hole 441 respectively extend to the corresponding two ends of the second wall part 44. One end of the first through hole 491 extends to the end of the first sub-wall part 451 towards the second wall part 44, and one end of the second through hole 492 extends to the end of the second sub-wall part 452 towards the second wall part 44. The third through hole 441 is opposite to and in communication with the first through hole 491 and the second through hole 492 along the second direction, and the guide part 1 is arranged through the third through hole 441.

[0115] The second wall portion 44 is formed with a third through hole 441 extending along the first direction. The third through hole 441 is in communication with the mounting space 42, so that at least part of the guide portion 1 can pass through the third through hole 441 and be assembled in the mounting space 42. Two ends of the third through hole 441 extend to corresponding two ends of the second wall portion 44 respectively. One end of the first through hole 491 extends to the end of the first sub-wall portion 451 towards the second wall portion 44, and one end of the second through hole 492 extends to the end of the second sub-wall portion 452 towards the second wall portion 44. Along the second direction, the third through hole 441 is opposite to the first through hole 491 and is in communication with the first through hole 491, and the third through hole 441 is opposite to the second through hole 492 and is in communication with the second through hole 492, so that the first through hole 491 and the second through hole 492 are both in communication with the third through hole 441, which is beneficial to improve the structural rationality of the protective cover 4, greatly reduces the assembly difficulty of the protective cover 4, and further reduces the risk of interference between the protective cover 4 and the guide portion 1 in the working process of the moving pair mechanism 100, thereby reducing the influence of the protective cover 4 on the cooperation between the moving portion 2 and the guide portion 1, and improving the use reliability of the moving pair mechanism 100.

[0116] In the above technical solution, by forming the second wall portion 44 with the third through hole 441 extending along the first direction, the third through hole 441 is in communication with the mounting space 42, and two ends of the third through hole 441 extend to corresponding two ends of the second wall portion 44 respectively. One end of the first through hole 491 extends to the end of the first sub-wall portion 451 towards the second wall portion 44, and one end of the second through hole 492 extends to the end of the second sub-wall portion 452 towards the second wall portion 44. The third through hole 441 is opposite to and in communication with the first through hole 491 and the second through hole 492 along the second direction. The guide portion 1 passes through the third through hole 441, so that the first through hole 491 and the second through hole 492 are both in communication with the third through hole 441, which is beneficial to improve the structural rationality of the protective cover 4, greatly reduces the assembly difficulty of the protective cover 4, and further reduces the risk of interference between the protective cover 4 and the guide portion 1 in the working process of the moving pair mechanism 100, thereby reducing the influence of the protective cover 4 on the cooperation between the moving portion 2 and the guide portion 1, and improving the use reliability of the moving pair mechanism 100.

[0117] According to some embodiments of the present application, referring to Figure 1 As shown in the figure, the protective cover 4 is formed with a relief hole 46 in communication with the mounting space 42, and the relief hole 46 is opposite to the part mounting portion 21 of the moving portion 2.

[0118] The moving part 2 can have a part mounting part 21. By mounting a part on the part mounting part 21, the moving part 2 can drive the part by driving the part mounting part 21. The protective cover 4 is formed with an avoiding hole 46, the avoiding hole 46 is communicated with the mounting space 42, and the avoiding hole 46 is opposite to the part mounting part 21 of the moving part 2, so that the avoiding hole 46 can smoothly avoid the part mounting part 21, thereby facilitating the assembly of the part mounting part 21 and the target part, reducing the assembly difficulty of the part mounting part 21 and the target part, and facilitating the realization of the function of the moving pair mechanism 100.

[0119] In the above technical solution, by forming the protective cover 4 with the avoiding hole 46 communicated with the mounting space 42, and the avoiding hole 46 opposite to the part mounting part 21 of the moving part 2, the avoiding hole 46 can smoothly avoid the part mounting part 21, thereby facilitating the assembly of the part mounting part 21 and the target part, reducing the assembly difficulty of the part mounting part 21 and the target part, and facilitating the realization of the function of the moving pair mechanism 100.

[0120] According to some embodiments of the present application, referring to Figure 1 As shown in the figure, part of the structure of the moving part 2 is assembled in the avoiding hole 46 and abuts against the side wall of the avoiding hole 46.

[0121] In the above technical solution, by forming the protective cover 4 with the avoiding hole 46 communicated with the mounting space 42, and the avoiding hole 46 opposite to the part mounting part 21 of the moving part 2, the avoiding hole 46 can smoothly avoid the part mounting part 21, thereby facilitating the assembly of the part mounting part 21 and the target part, reducing the assembly difficulty of the part mounting part 21 and the target part, and facilitating the realization of the function of the moving pair mechanism 100.

[0122] In the above technical solution, by forming the protective cover 4 with the avoiding hole 46 communicated with the mounting space 42, and the avoiding hole 46 opposite to the part mounting part 21 of the moving part 2, the avoiding hole 46 can smoothly avoid the part mounting part 21, thereby facilitating the assembly of the part mounting part 21 and the target part, reducing the assembly difficulty of the part mounting part 21 and the target part, and facilitating the realization of the function of the moving pair mechanism 100.

[0123] According to some embodiments of the present application, referring to Figure 1As shown, the protective cover 4 can include: a first sub-protective cover 47 and a second sub-protective cover 48, the first sub-protective cover 47 and the second sub-protective cover 48 are oppositely arranged along the third direction, and the first sub-protective cover 47 and the second sub-protective cover 48 are detachably connected.

[0124] Wherein, along the third direction, that is, the Z direction in the Figure 1 first sub-protective cover 47 and the second sub-protective cover 48 are oppositely arranged, so that the first sub-protective cover 47 and the second sub-protective cover 48 jointly define the mounting space 42. The first sub-protective cover 47 and the second sub-protective cover 48 are detachably connected, for example: the first sub-protective cover 47 and the second sub-protective cover 48 can be detachably connected by bolts, and the first sub-protective cover 47 and the second sub-protective cover 48 can also be detachably connected by a cable tie. This arrangement is beneficial to improve the working stability of the moving pair mechanism 100 and reduce the risk of separation and falling of the first sub-protective cover 47 and the second sub-protective cover 48 when the moving part 2 moves relative to the guide part 1 along the first direction.
