Star-shaped sleeve conveying device and attitude adjustment mechanism

Abstract

The present invention relates to a star-shaped sleeve conveying device and an attitude adjustment mechanism. When the pressing member pushes the star-shaped sleeve to move towards the first guiding member until the star-shaped sleeve is in abutting cooperation with the first guiding member, the moving member can drive the pressing member to reciprocate in the first direction. Since the first guiding member is stationary and the pressing member moves in the first direction, the arc contact surface of the star-shaped sleeve in contact with the pressing member is subjected to a frictional force in the tangential direction, so that the star-shaped sleeve rotates around its own central axis, thereby adjusting the attitude of the star-shaped sleeve during the conveying process for circumferential positioning, without the need to convey the star-shaped sleeve to a separate positioning mechanism, simplifying the structure and reducing the cost.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0031] like Figure 1 As shown, the six grooves 11 and the six abutment protrusions 12 on the star sleeve 10 are evenly distributed on its circumferential side wall. When positioning the star sleeve 10 in the circumferential direction during transportation, it is difficult to position it from the shaft hole and the arc abutment surface 13. Therefore, the center lines of the two opposite grooves 11 are selected as the positioning reference, as shown in FIG. Figure 1 As shown, the dotted line A is selected as the positioning reference. Those skilled in the art can understand that there are three such positioning references on a star sleeve 10, that is, there are three such dotted lines A. It is only necessary to use one of the positioning references as a standard to position the star sleeve 10 in the circumferential direction so that the postures of the various star sleeves 10 can be kept consistent.

[0032] In one embodiment, a star sleeve 10 conveying device is provided, so that the star sleeve 10 can be conveyed to retrieve or pick up the star sleeve 10 .

[0033] Among them, the star sleeve 10 conveying device includes an attitude adjustment mechanism 100, so that the attitude of the star sleeve 10 during conveying can be adjusted by using the attitude adjustment mechanism 100, so that the attitudes of the star sleeves 10 are kept consistent, which is convenient for taking or picking up the star sleeves 10.

[0034] It should be noted that taking or picking up the star sleeve 10 can be realized by grasping or picking up through existing manipulators or the like. Since it belongs to the prior art, it will not be elaborated here.

[0035] Such as Figure 2 and Figure 3 As shown, specifically, the attitude adjustment mechanism 100 includes a conveying member 110, a first guiding member 120 and an attitude adjustment assembly 130.

[0036] Among them, the conveying member 110 can be in the form of a conveyor belt or the like, and can convey the star sleeve 10 placed thereon in the first direction (such as Figure 2 and Figure 3 the B direction shown).

[0037] It can be understood that the first direction can be any direction designed according to the actual site conditions and conveying requirements. For example, it can be from left to right or from right to left, and there is no limit.

[0038] Among them, the first guiding member 120 can be in the form of a guiding plate or a guiding strip, and the first guiding member 120 can be arranged on one side of the conveying member 110 in a form such as screwing or clamping.

[0039] Such as Figure 4 As shown, among them, the attitude adjustment assembly 130 includes a pressing member 131 and a moving member 132.

[0040] Specifically, the pressing member 131 is arranged at a relative interval with the first guiding member 120, so as to form a conveying channel between the pressing member 131 and the first guiding member 120, and the pressing member 131 can reciprocate in a direction perpendicular to the first direction.

[0041] More specifically, when the pressing member 131 moves in a direction perpendicular to the first direction toward the first guide member 120, the distance between the pressing member 131 and the first guide member 120 becomes smaller, so that the star sleeve 10 passing through the conveying channel can be resisted, and then the pressing member 131 is used to push the star sleeve 10 passing through the conveying channel to move in a direction close to the first guide member 120 until the star sleeve 10 is resisted on the first guide member 120, that is, the pressing member 131 and the first guide member 120 respectively resist the opposite sides of the star sleeve 10, thereby achieving a clamping effect on the star sleeve 10, at which time, the star sleeve 10 cannot be conveyed with the conveying member 110. When the pressing member 131 moves in a direction perpendicular to the first direction toward the direction away from the first guide member 120, the distance between the pressing member 131 and the first guide member 120 becomes larger, so that the clamped star sleeve 10 can be released, so that the star sleeve 10 can be conveyed synchronously with the conveying member 110 along the first direction.

[0042] Optionally, the pressing member 131 may be in the form of a cylinder or a hydraulic cylinder, which reciprocates along the first direction in a telescopic manner and combines with the first guide member 120 to clamp or release the star sleeve 10 .

[0043] Among them, the moving part 132 is connected with the pressing part 131 by transmission, and when the pressing part 131 pushes the star sleeve 10 to move toward the direction close to the first guide part 120 so that the star sleeve 10 and the first guide part 120 are in conflict with each other, the moving part 132 can drive the pressing part 131 to move back and forth in the first direction. Since the first guide part 120 is stationary and the pressing part 131 moves in the first direction, the arc contact surface 13 where the star sleeve 10 and the pressing part 131 are in contact is subjected to friction in the tangential direction, thereby causing the star sleeve 10 to rotate around its own central axis, thereby adjusting the posture of the star sleeve 10 during the conveying process for positioning in the circumferential direction, and there is no need to convey the star sleeve 10 to a separate positioning mechanism, thereby simplifying the structure and reducing the cost.

[0044] It can be understood that the moving member 132 drives the pressing member 131 to move back and forth in the first direction, which means that the moving member 132 can drive the pressing member 131 to move along the first direction and the opposite direction of the first direction.

[0045] Optionally, if the arc length of an arc contact surface 13 of the star-shaped sleeve 10 is S, the moving stroke of the moving member 132 in the first direction is L. In this way, after the pressing member 131 and the first guiding member 120 clamp the star-shaped sleeve 10, the moving member 132 drives the pressing member 131 to move L in the first direction, causing the star-shaped sleeve 10 to rotate around its own central axis. Since S < L < 2S, the star-shaped sleeve 10 can be rotated to make the two opposite grooves 11 correspond to the pressing member 131 and the first guiding member 120 respectively, that is, to rotate the star-shaped sleeve 10 to make one of the dotted lines A perpendicular to the first direction, so as to complete the positioning and attitude adjustment of the star-shaped sleeve 10 in the circumferential direction during the conveying process.

[0046] Among them, L can be 1.1S, 1.2S, 1.3S, 1.4S, 1.5S, 1.6S, 1.7S, 1.8S, 1.9S, and can be adaptively adjusted according to the actual clamping situation of the star-shaped sleeve 10, as long as it satisfies that the star-shaped sleeve 10 is rotated to make one of the dotted lines A perpendicular to the first direction. L is preferably 1.5S, so that the frictional force received by the star-shaped sleeve 10 can ensure that the star-shaped sleeve 10 is rotated to make one of the dotted lines A perpendicular to the first direction.

[0047] Among them, the moving member 132 drives the pressing member 131 to reciprocate in the first direction. The pressing member 131 can be driven to move in the first direction by the telescopic movement of a cylinder or a hydraulic cylinder, or the pressing member 131 can be driven to move in the first direction by the cooperation of a gear and a rack, or the pressing member 131 can be driven to move in the first direction by a linear motor drive form.

[0048] In addition, in order to ensure that the pressing member 131 can accurately push the star-shaped sleeve 10 when moving towards the first guiding member 120 perpendicular to the first direction. As Figure 4 shown, optionally, the attitude adjustment mechanism 100 further includes a first detection element 140, so as to use the first detection element 140 to detect whether a star-shaped sleeve 10 is conveyed to the conveying channel between the first guiding member 120 and the pressing member 131. And the first detection element 140 is electrically connected to the pressing member 131, so that when the first detection element 140 detects that a star-shaped sleeve 10 is conveyed into the conveying channel, the pressing member 131 is controlled to move towards the first guiding member 120 perpendicular to the first direction, and then the star-shaped sleeve 10 in the conveying channel can be accurately clamped by the pressing member 131 and the first guiding member 120, avoiding misoperation or delayed operation.

[0049] Among them, the first detection element 140 can be a position sensor, a photoelectric switch or other existing components that can detect the presence or absence of the star-shaped sleeve 10. And along the first direction, the first detection element 140 can be arranged at the upstream position of the pressing member 131.

[0050] In addition, the posture adjustment assembly 130 further includes a mounting seat 133 , so that the pressing member 131 can be mounted on the mounting seat 133 .

[0051] like Figure 4 As shown, specifically, a sliding portion 1331 extending along the first direction is provided on the mounting seat 133, and the clamping member 131 is slidably matched with the sliding portion 1331. In this way, when the moving member 132 drives the clamping member 131 to reciprocate in the first direction, the sliding match between the sliding portion 1331 and the clamping member 131 is utilized to guide and limit the movement of the clamping member 131, so that the clamping member 131 can move more accurately and smoothly in the first direction, thereby being able to accurately adjust the posture of the star sleeve 10.

[0052] The sliding part 1331 may be in the form of a slide rail, and accordingly, a slide groove matching the slide rail may be provided on the pressing member 131. The mounting seat 133 may be fixed on the gantry bracket by screw connection, welding or clamping.

[0053] In the actual conveying process, in order to prevent the star sleeve 10 from deflecting during the conveying process after the posture adjustment is completed, the posture changes. Figure 3 As shown, optionally, the posture adjustment mechanism 100 further includes a second guide member 150 and a spacing adjustment component 160 .

[0054] Among them, the second guide member 150 is arranged on the other side of the conveying member 110. Along the first direction, the second guide member 150 is arranged downstream of the clamping member 131 and is arranged opposite to at least part of the first guide member 120, that is, the second guide member 150 and part of the first guide member 120 are arranged relatively spaced apart to form a guide channel.

[0055] Furthermore, the first guide member 120 and the second guide member 150 are both connected to the spacing adjustment assembly 160 in a transmission manner, so that the spacing between the first guide member 120 and the second guide member 150 is adjustable. In this way, after the star-shaped sleeve 10 completes the posture adjustment in the conveying channel, it enters the guide channel formed by the relative spacing between the first guide member 120 and the second guide member 150, and the spacing adjustment assembly 160 adjusts the spacing between the first guide member 120 and the second guide member 150 to adjust the width of the guide channel, so that the width of the guide channel matches the outer diameter of the star-shaped sleeve 10, thereby limiting the deflection of the star-shaped sleeve 10 during the conveying process, so that the star-shaped sleeve 10 maintains the adjusted posture for conveying. Furthermore, by using the spacing adjustment assembly 160 to adjust the spacing between the first guide member 120 and the second guide member 150, the guide channel can also be compatible with the conveying requirements of star-shaped sleeves 10 of different sizes, and has strong versatility.

[0056] Among them, the second guiding member 150 can be in the form of a guiding plate or a guiding strip.

[0057] Among them, the spacing adjustment assembly 160 adjusts the spacing between the first guiding member 120 and the second guiding member 150, which can be achieved by pushing through a cylinder or a hydraulic cylinder in a direction perpendicular to the first direction, or by driving through the cooperation of a gear and a rack in a direction perpendicular to the first direction, or by linkage in the form of a linear motor drive.

[0058] Specifically, in the embodiment of the present application, the spacing adjustment assembly 160 includes a servo motor, a lead screw having a first hand of thread and a second hand of thread, a first nut sleeved on the first hand of thread, and a second nut sleeved on the second hand of thread. And, the first hand of thread and the second hand of thread have opposite hands of thread.

[0059] Specifically, the lead screw extends in a direction perpendicular to the first direction. By using the transmission connection between the servo motor and the lead screw, the lead screw can be driven to rotate forward or backward around its own central axis. Thus, when the lead screw rotates forward and backward, the first nut and the second nut approach or move away from each other in a direction perpendicular to the first direction. Combining that the first nut is connected to the first guiding member 120 by screwing or clamping, etc., and the second nut is connected to the second guiding member 150 by screwing or clamping, etc., thereby driving the first guiding member 120 and the second guiding member 150 to approach or move away from each other in a direction perpendicular to the first direction, and further adjusting the width of the guiding channel.

[0060] In addition, in order to ensure the uniformity of the width of the guiding channel. As Figure 3 shown, optionally, the spacing adjustment assembly 160 further includes a first guide rail 170 and a second guide rail 180 that are relatively spaced apart in the first direction.

[0061] Specifically, both the first guide rail 170 and the second guide rail 180 extend in a direction perpendicular to the first direction. And, both ends of the first guiding member 120 are in guiding cooperation with the first guide rail 170 and the second guide rail 180 respectively, and both ends of the second guiding member 150 are in guiding cooperation with the first guide rail 170 and the second guide rail 180 respectively. In this way, the first guide rail 170 and the second guide rail 180 can guide the approach or separation between the first guiding member 120 and the second guiding member 150, so that both the first guiding member 120 and the second guiding member 150 can move smoothly and accurately in a direction perpendicular to the first direction, without tilting or offsetting, ensuring the uniformity of the width of the guiding channel, and effectively restricting the deflection of the star-shaped sleeve 10 during transportation in the guiding channel, so that the star-shaped sleeve 10 is transported while maintaining the adjusted posture.

[0062] Among them, the two ends of the first guiding member 120 are respectively in guiding cooperation with the first guide rail 170 and the second guide rail 180, which can be realized by sliding fit or by rolling fit.

[0063] Among them, the two ends of the second guiding member 150 are respectively in guiding cooperation with the first guide rail 170 and the second guide rail 180, which can be realized by sliding fit or by rolling fit.

[0064] In addition, when the star-shaped sleeves 10 are conveyed on the conveying member 110, there is also a problem of mutual accumulation, which affects the attitude adjustment.

[0065] It can be understood that in order to ensure that the mutual movement of the first guiding member 120 and the second guiding member 150 does not interfere with the attitude adjustment assembly 130, there may also be intermediate elements in the connection between the first guiding member 120 and the first guide rail 170 and the second guide rail 180. For example, the guiding cooperation between the first guiding member 120 and the first guide rail 170 and the second guide rail 180 can be indirectly realized through an intermediate connecting plate; similarly, there may also be intermediate elements in the connection between the second guiding member 150 and the first guide rail 170 and the second guide rail 180. For example, the guiding cooperation between the second guiding member 150 and the first guide rail 170 and the second guide rail 180 can be indirectly realized through an intermediate connecting plate.

[0066] Such as Figure 3 and Figure 5 As shown, optionally, the attitude adjustment mechanism 100 further includes a material distributing assembly 190.

[0067] Specifically, along the first direction, the material distributing assembly 190 is arranged upstream of the attitude adjustment assembly 130, so as to arrange the star-shaped sleeves 10 at equal intervals on the conveying member 110, so that the star-shaped sleeves 10 are conveyed into the conveying channel at equal intervals for attitude adjustment, and the attitude adjustment between the star-shaped sleeves 10 can be carried out without interference from each other, ensuring the accuracy of attitude adjustment.

[0068] Such as Figure 3 and Figure 5 As shown, specifically, the material distributing assembly 190 includes a first blocking member 191, a second blocking member 192, a second detecting element 193 and a third detecting element 194 which are electrically connected to each other.

[0069] Among them, the first blocking member 191 and the second blocking member 192 are arranged at intervals along the first direction, and both the first blocking member 191 and the second blocking member 192 can block or release the star-shaped sleeves 10 on the conveying member 110, that is, both the first blocking member 191 and the second blocking member 192 have two states: a blocking state and a releasing state.

[0070] Optionally, the first blocking member 191 may be in the form of clamping and blocking. In this case, the first blocking member 191 may be the first clamping jaw. The first clamping jaw clamps the star-shaped sleeve 10 to limit the star-shaped sleeve 10 from being conveyed along the first direction by the conveying member 110, so that the star-shaped sleeve 10 is held in the clamped position. Moreover, when the first clamping jaw releases the star-shaped sleeve 10 and allows the star-shaped sleeve 10 to pass, the star-shaped sleeve 10 can continue to be conveyed along the first direction on the conveying member 110. The first blocking member 191 may also be in the form of abutting and blocking. In this case, the first blocking member 191 may be the first blocking cylinder. The first blocking cylinder extends to abut against the star-shaped sleeve 10 to limit the star-shaped sleeve 10 from being conveyed along the first direction by the conveying member 110, so that the star-shaped sleeve 10 is held in the abutted position. Moreover, when the first blocking cylinder contracts and allows the star-shaped sleeve 10 to pass, the star-shaped sleeve 10 can continue to be conveyed along the first direction on the conveying member 110.

[0071] Optionally, the second blocking member 192 may be in the form of clamping and blocking. In this case, the second blocking member 192 may be the second clamping jaw. The second clamping jaw clamps the star-shaped sleeve 10 to limit the star-shaped sleeve 10 from being conveyed along the first direction by the conveying member 110, so that the star-shaped sleeve 10 is held in the clamped position. Moreover, when the second clamping jaw releases the star-shaped sleeve 10 and allows the star-shaped sleeve 10 to pass, the star-shaped sleeve 10 can continue to be conveyed along the first direction on the conveying member 110. The second blocking member 192 may also be in the form of abutting and blocking. In this case, the second blocking member 192 may be the second blocking cylinder. The second blocking cylinder extends to abut against the star-shaped sleeve 10 to limit the star-shaped sleeve 10 from being conveyed along the first direction by the conveying member 110, so that the star-shaped sleeve 10 is held in the abutted position. Moreover, when the second blocking cylinder contracts and allows the star-shaped sleeve 10 to pass, the star-shaped sleeve 10 can continue to be conveyed along the first direction on the conveying member 110.

[0072] Meanwhile, the first blocking member 191 is arranged relatively close to the attitude adjustment assembly 130 with respect to the second blocking member 192. That is, when the star-shaped sleeve 10 moves along the first direction on the conveying member 110, the star-shaped sleeve 10 first passes through the position where the second blocking member 192 is arranged, then passes through the position where the first blocking member 191 is arranged, and then the attitude of the star-shaped sleeve 10 is adjusted by the attitude adjustment assembly 130.

[0073] Wherein, the second detection element 193 and the third detection element 194 are arranged at intervals along the first direction, and the third detection element 194 is arranged relatively close to the attitude adjustment assembly 130 with respect to the second detection element 193. That is, when the star-shaped sleeve 10 moves along the first direction on the conveying member 110, the star-shaped sleeve 10 first passes through the position where the second detection element 193 is arranged, then passes through the position where the third detection element 194 is arranged, and then the attitude of the star-shaped sleeve 10 is adjusted by the attitude adjustment assembly 130.

[0074] Specifically, the second detection element 193 is used to detect whether the star-shaped sleeve 10 is blocked at the first blocking member 191, that is, the second detection element 193 can detect whether the star-shaped sleeve 10 is transported to the first blocking member 191 and blocked by the first blocking member 191 in the blocking state. The third detection element 194 is used to detect whether the star-shaped sleeve 10 passes through the detection position corresponding to the third detection element 194.

[0075] More specifically, each star-shaped sleeve 10 is transported on the conveyor 110 in the first direction. At this time, the first blocking member 191 is in the blocking state and the second blocking member 192 is in the releasing state. When the second detection element 193 detects that the star-shaped sleeve 10 is blocked at the first blocking member 191, that is, when the foremost star-shaped sleeve 10 (hereinafter referred to as the first star-shaped sleeve 10) is transported in the first direction and blocked by the first blocking member 191, the second blocking member 192 switches from the releasing state to the blocking state, so as to use the second blocking member 192 to block the star-shaped sleeve 10 adjacent to the first star-shaped sleeve 10 (hereinafter referred to as the second star-shaped sleeve 10). Then the first blocking member 191 switches from the blocking state to the releasing state, so that the first star-shaped sleeve 10 is transported on the conveyor 110 in the first direction. When the third detection element 194 detects the first star-shaped sleeve 10, that is, when the third detection element 194 detects that the first star-shaped sleeve 10 passes through the detection position corresponding to the third detection element 194, the first blocking member 191 switches from the releasing state to the blocking state, and the second blocking member 192 switches from the blocking state to the releasing state. In this way, each star-shaped sleeve 10 is arranged at equal intervals on the conveyor 110 and then transported to the attitude adjustment assembly 130 for attitude adjustment. The attitude adjustment between each star-shaped sleeve 10 can be carried out without interference with each other, ensuring the accuracy of attitude adjustment.

[0076] Among them, the second detection element 193 and the third detection element 194 can be photoelectric switches, proximity switches or other existing elements that can detect the position of the star-shaped sleeve 10.

[0077] It should be noted that the electrical connection method can be a wired connection through a wire, or a wireless connection such as Bluetooth transmission. There can also be intermediate elements, such as setting a central control unit such as a single-chip microcomputer, and using the central control unit to realize signal interaction and transmission.

[0078] It should be noted that the upstream refers to the side of the conveyor 110 closer to the feeding mechanism. Correspondingly, the downstream refers to the side of the conveyor 110 farther from the feeding mechanism. Specifically, when the conveyor 110 transports from left to right, the upstream refers to the side closer to the left, and the downstream refers to the side closer to the right.

[0079] The posture adjustment mechanism 100 of the above embodiment is simpler in structure compared with the existing method of circumferentially positioning the star sleeve 10 by using a vibrating bowl feeder combined with a vision system. It can synchronously adjust the posture of the star sleeve 10 during the conveying process, save costs, reduce the floor space, and also reduce the failure rate.

[0080] It should be noted that "a certain body" and "a certain part" can be a part of the corresponding "component", that is, "a certain body" and "a certain part" are integrally formed with the "other parts of the component"; or they can be an independent component separable from the "other parts of the component", that is, "a certain body" and "a certain part" can be manufactured independently and then combined with the "other parts of the component" into a whole. The expressions of "a certain body" and "a certain part" in this application are only one embodiment for the convenience of reading, rather than a limitation on the protection scope of this application. As long as the above features are included and the functions are the same, it should be understood as an equivalent technical solution of this application.

[0081] It should be noted that the components included in the "unit", "assembly", "mechanism", and "device" of this application can also be flexibly combined, that is, modular production can be carried out according to actual needs to facilitate modular assembly. The division of the above components in this application is only one embodiment for the convenience of reading, rather than a limitation on the protection scope of this application. As long as the above components are included and the functions are the same, it should be understood as an equivalent technical solution of this application.

[0082] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention. The term "and / or" used in the present invention includes any and all combinations of one or more of the related listed items.

[0083] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0084] In the present invention, unless otherwise clearly specified or limited, the terms "mounted", "connected", "coupled", "fixed", etc. shall be construed broadly. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0085] In the present invention, unless otherwise clearly specified or limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely means that the first feature has a higher horizontal height than the second feature. The first feature being "under", "below" and "beneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely means that the first feature has a lower horizontal height than the second feature.

[0086] It should be noted that when an element is referred to as being "fixed to", "arranged on", "secured to" or "mounted on" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. Further, when an element is considered to be "fixed and drivingly connected" to another element, the two can be fixed in a detachable connection manner or a non-detachable connection manner, as long as power transmission can be achieved, such as socket connection, snap connection, integrally formed fixation, welding, etc., which can be achieved in the prior art and will not be elaborated here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is perpendicular, but due to manufacturing and assembly effects, there may be a certain vertical error. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0087] It should also be understood that when interpreting the connection relationship or positional relationship of elements, although not explicitly described, the connection relationship and positional relationship are interpreted to include an error range, and this error range should be within the acceptable deviation range of a specific value determined by those skilled in the art. For example, "about", "approximately" or "substantially" may mean within one or more standard deviations, which will not be limited herein.

[0088] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0089] The above embodiments only express several implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be understood as a limitation to the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the invention patent should be subject to the appended claims.
