Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and in particular to a transfer tooling and a battery manufacturing system. Background Technology

[0002] Energy conservation and emission reduction are key to sustainable development, which in turn promotes the adjustment of the energy structure and drives the development and application of battery technology. The key to the development of battery technology lies in electrochemical energy storage technology. Due to its advantages such as high energy density, good cycle capability, high operating voltage, environmental friendliness, and low self-discharge, it has been widely used in portable electronics, electric vehicles, and energy storage systems.

[0003] A complete battery production process requires numerous production steps, each consisting of an independent piece of equipment. After completing a step, the product must be transferred to the next step's equipment. However, during the transfer process, problems such as products detaching from the transfer equipment and being damaged can easily occur. Summary of the Invention

[0004] The main purpose of this application is to provide a transfer tooling and battery production system, which aims to solve the technical problems existing in the prior art, such as the product easily detaching from the transfer equipment and damaging the material during the product transfer process.

[0005] To address the aforementioned problems, this application provides a transfer fixture, comprising a transfer body and a limiting module. The transfer body extends along a first direction and includes an inlet end and a transfer shaft, which is used to mount a sleeve to be transferred. The limiting module includes a transmission assembly, a pressing part, and a limiting part. The limiting part is connected to the transmission assembly, which drives the limiting part to move to a first position in a second direction intersecting the first direction, so that the limiting part stops the sleeve to be transferred from the inlet end of the transfer shaft along the first direction at the first position. The transmission assembly includes a first guide rod, a second guide rod, and a rotating sleeve. The first guide rod is connected to the side of the limiting part facing the pressing part, and the second guide rod is connected to the side of the pressing part facing the limiting part. The rotating sleeve is connected to both the first guide rod and the second guide rod. One of the first guide rod and the second guide rod moves in the second direction to drive the rotating sleeve to rotate around the second direction. During the rotation of the rotating sleeve around the second direction, the other of the first guide rod and the second guide rod moves in the second direction.

[0006] Through the above embodiments, the limiting part and the pressing part can move relative to each other or in opposite directions in the second direction through the cooperation of the first guide rod, the second guide rod and the rotating sleeve. This allows the limiting part to move together with the pressing part in the second direction by applying an external force along the second direction. This facilitates the limiting part stopping the sleeve to be transported from the feed end of the transfer shaft in the first direction when the limiting part is not in the first position. It also facilitates the sleeve to be transported from the feed end of the transfer shaft in the first direction or from the feed end to the transfer shaft when the limiting part is not in the first position. This reduces the risk of the sleeve to be transported accidentally detaching from the transfer fixture, improves the transfer efficiency of the sleeve to be transported and the reliability of the transfer process, and also allows the limiting part and the pressing part to move relative to each other or in opposite directions in the second direction through a simple product structure, reducing the volume of the transfer fixture and improving the compactness of the transfer fixture.

[0007] In some embodiments, the transfer body has an internal mounting cavity, and the side wall of the mounting cavity has a first through hole. The first through hole extends along a second direction intersecting the first direction and is located between the feed end and the transfer shaft in the first direction. A transmission assembly is disposed in the mounting cavity and connected to the transfer body. A limiting part corresponds to the first through hole in the second direction, and at a first position, the limiting part protrudes from the outer surface of the transfer body in the second direction. Thus, by disposing of the transmission assembly in the mounting cavity and connecting it to the transfer body, the internal space of the transfer body is rationally utilized, reducing the volume of the transfer fixture and improving its compactness. Simultaneously, the limiting part, corresponding to the first through hole in the second direction and protruding from the outer surface of the transfer body in the second direction at the first position, further reduces the risk of the sleeve to be transported accidentally detaching from the transfer fixture, improving the transfer efficiency of the sleeve to be transported and the reliability of the transfer process.

[0008] In some embodiments, the limiting portion is provided with a stop surface and a first inclined surface. The stop surface faces the transfer shaft, and the first inclined surface is located on the side of the limiting portion away from the transmission assembly. The first inclined surface is inclined relative to the first direction, and the first inclined surface and the stop surface face opposite to each other. Thus, the stop surface facing the transfer shaft can prevent the sleeve to be transported from moving out of the feed end of the transfer shaft along the first direction when the limiting portion is in the first position, thereby reducing the risk of the sleeve to be transported accidentally detaching from the transfer fixture. The first inclined surface is inclined relative to the first direction, and the first inclined surface and the stop surface face opposite to each other, so that the design of the first inclined surface can reduce the interference of the limiting portion with the movement of the sleeve to be transported from the feed end to the transfer body along the first direction, thereby improving the transfer efficiency of the sleeve to be transported.

[0009] In some embodiments, the transmission assembly is further configured to move the limiting portion from a first position to a second position in a second direction, where it does not protrude from the outer surface of the transfer body. Thus, the transmission assembly further drives the limiting portion to move in the second direction, causing it to move from the first position to the second position, reducing interference from the limiting portion as the sleeve to be transported moves from the feed end along the first direction to the transfer body, thereby improving the transfer efficiency of the sleeve to be transported.

[0010] In some embodiments, the transfer body includes a central support plate, a first side plate, and a first elastic member. The first side plate is connected to a limiting part, and the central support plate is spaced apart on the side of the first side plate opposite to the limiting part. The first elastic member is elastically supported between the first side plate and the central support plate, and the first side plate is used to move with the limiting part in a second direction. Thus, the first elastic member elastically supports the first side plate and the central support plate, and the first side plate is used to move with the limiting part in a second direction, facilitating the limiting part to reset from the second position and remain in the first position under the action of the first elastic member, further reducing the risk of the sleeve to be transported accidentally detaching from the transfer fixture, improving the transfer efficiency of the sleeve to be transported, and enhancing the reliability of the transfer process.

[0011] In some embodiments, the sidewall of the transfer body is provided with a second through hole extending along a second direction. The first through hole and the second through hole are located on opposite sides of the mounting cavity in the second direction. The pressing part corresponds to the second through hole in the second direction. When the limiting part is in the first position, the pressing part protrudes from the outer surface of the transfer body in the second direction. When the limiting part is in the second position, the pressing part does not protrude from the outer surface of the transfer body in the second direction. Thus, when the limiting part is in the first position, the pressing part protrudes from the outer surface of the transfer body in the second direction. When the limiting part is in the second position, the pressing part does not protrude from the outer surface of the transfer body in the second direction. By applying an external force along the second direction to the pressing part, the limiting part moves along with the pressing part in the second direction, allowing the limiting part to switch between the first and second positions via the pressing part, thereby improving the transfer efficiency of the sleeve to be transported and the reliability of the transfer process.

[0012] In some embodiments, the sidewall of the rotating sleeve is provided with a first helical groove and a second helical groove, the first helical groove and the second helical groove having opposite rotation directions. A first guide rod includes a first protrusion, and a second guide rod includes a second protrusion. The first protrusion is disposed in the first helical groove, and the second protrusion is disposed in the second helical groove. The first protrusion moves in a second direction to drive the rotating sleeve to rotate around the second direction via the first helical groove. During the rotation of the rotating sleeve around the second direction, the second protrusion moves in the second direction via the second helical groove. Alternatively, the second protrusion moves in the second direction to drive the rotating sleeve to rotate around the second direction via the second helical groove. During the rotation of the rotating sleeve around the second direction, the first protrusion moves in the second direction via the first helical groove. Thus, the first helical groove and the second helical groove have opposite rotation directions, and the first protrusion is disposed in the first helical groove, and the second protrusion is disposed in the second helical groove. This allows for a simpler structure to achieve relative or opposite movement of the limiting part and the pressing part in the second direction, making reasonable use of the internal space of the transfer body, further reducing the volume of the transfer tooling, and improving the compactness of the transfer tooling.

[0013] In some embodiments, the first guide rod further includes a first rod body, which extends along a second direction and is respectively connected to a limiting portion and a first protrusion. The first protrusion protrudes from the sidewall of the first rod body in a first direction. The second guide rod further includes a second rod body, which extends along a second direction and is respectively connected to a pressing portion and a second protrusion. The second protrusion protrudes from the sidewall of the second rod body in a second direction. A third through hole extending along the second direction is rotatably fitted, and at least part of the first rod body and the second rod body are located within the third through hole. Thus, by rotatably fitting the third through hole extending along the second direction, and at least part of the first rod body and the second rod body being located within the third through hole, the size of the limiting module in the second direction is reduced, the internal space of the transfer body is rationally utilized, the volume of the transfer fixture is further reduced, and the compactness of the transfer fixture is improved.

[0014] In some embodiments, the limiting module includes a central support plate and a bearing. The central support plate has a fourth through hole extending along a second direction. The bearing is disposed within the fourth through hole and fixed to the central support plate. A rotating sleeve is partially disposed within the bearing. Thus, with the bearing disposed within the fourth through hole and fixed to the central support plate, and the rotating sleeve partially disposed within the bearing, the bearing can be used to fix the rotating sleeve relative to it and to allow the auxiliary rotating sleeve to rotate around the second direction. This allows for relative or opposite movement of the limiting part and the pressing part in the second direction through a simple product structure, making efficient use of the internal space of the transfer body, reducing the volume of the transfer tooling, and improving the compactness of the transfer tooling.

[0015] In some embodiments, the limiting module includes a first fixing member, which includes a first column and a second column. The first column is inserted into a central support plate, and the second column is connected to the side of the first column facing the limiting portion and abuts against the surface of the bearing facing the limiting portion. And / or, the limiting module includes a second fixing member, which includes a third column and a fourth column. The third column is inserted into a central support plate, and the fourth column is connected to the side of the third column facing the pressing portion and abuts against the surface of the bearing facing the pressing portion. Thus, the second column is connected to the side of the first column facing the limiting part, and the second column abuts against the surface of the bearing facing the limiting part, so as to fix the bearing from the surface of the bearing facing the limiting part by the first fixing member and the middle support plate, and / or, the fourth column is connected to the side of the third column facing the pressing part, and the fourth column abuts against the surface of the bearing facing the pressing part, so as to fix the bearing from the surface of the bearing facing the limiting part by the second fixing member and the middle support plate. This makes reasonable use of the internal space of the transfer body, reduces the volume of the transfer tooling, and improves the compactness of the transfer tooling.

[0016] In some embodiments, the rotating sleeve includes a first rotating segment and a second rotating segment interconnected in a second direction. The dimension of the first rotating segment in the first direction is larger than that of the second rotating segment in the first direction. The first rotating segment abuts against one side of the bearing in the second direction, and the second rotating segment is partially disposed inside the bearing. A snap-fit ​​ring groove is provided on the outer peripheral side of the second rotating segment. The limiting module includes a snap-fit ​​member, which snaps into the snap-fit ​​ring groove and abuts against the other side of the bearing in the second direction. Thus, the first rotating segment abuts against one side of the bearing in the second direction, and the snap-fit ​​member snaps into the snap-fit ​​ring groove and abuts against the other side of the bearing in the second direction, thereby achieving the fixation of the bearing and the rotating sleeve through a simple structure, making reasonable use of the internal space of the transfer body, reducing the volume of the transfer tooling, and improving the compactness of the transfer tooling.

[0017] In some embodiments, the limiting module includes a central support plate, a second side plate, and a second elastic member. The second side plate is connected to the pressing part, and the central support plate is spaced apart on the side of the second side plate opposite to the pressing part. The second elastic member is elastically supported between the second side plate and the central support plate, and the second side plate is used to move with the pressing part in a second direction. Thus, the elastic support of the second elastic member between the second side plate and the central support plate, and the second side plate's movement in the second direction, facilitates the resetting of the limiting part from the second position to the first position via the transmission assembly, further reducing the risk of the sleeve accidentally detaching from the transfer fixture, improving the transfer efficiency of the sleeve and the reliability of the transfer process.

[0018] In some embodiments, the pressing part is provided with a second inclined surface and a third inclined surface, which are located on the side of the limiting part away from the transmission assembly. The second and third inclined surfaces are inclined relative to the first direction, and their orientations are opposite. Therefore, by pressing the second and third inclined surfaces relative to the first direction and with their opposite orientations, an external force can be applied to the pressing part, causing the pressing part to move in the second direction. This, in turn, drives the limiting part to move in the second direction via the transmission assembly, improving the transfer efficiency of the sleeve to be transported and the reliability of the transfer process.

[0019] In some embodiments, the limiting module further includes a push rod assembly, which is used to apply an external force along a second direction to the transmission assembly, so that the transmission assembly drives the limiting part to move in the second direction. Thus, the push rod assembly applies an external force along a second direction to the transmission assembly, thereby driving the limiting part to move in the second direction, improving the transfer efficiency of the sleeve to be transported and the reliability of the transfer process.

[0020] In some embodiments, the transmission assembly includes a central support plate, a first side plate, and a first elastic member. The central support plate is spaced apart from the side of the first side plate opposite to the limiting portion. The first side plate includes a plate body and a mating portion, which are connected. The plate body is also connected to the limiting portion. The first elastic member is elastically supported between the plate body and the central support plate. A push rod assembly is used to apply an external force along a second direction to the mating portion. Thus, the push rod assembly applies an external force along a second direction to the mating portion, causing the transmission assembly to drive the limiting portion to move in the second direction, further improving the transfer efficiency of the sleeve to be transported and the reliability of the transfer process.

[0021] In some embodiments, the push rod assembly includes a push shaft inserted into the feed end and extending along a first direction. A mating portion includes a fourth inclined surface facing the push shaft, and the push shaft is used to move along the first direction to abut against the fourth inclined surface. Thus, the push shaft extends along the first direction and moves along the first direction to abut against the fourth inclined surface, achieving movement of the limiting portion in a second direction through a simple product structure, rationally utilizing the internal space of the transfer body, reducing the volume of the transfer tooling, and improving the compactness of the transfer tooling.

[0022] In some embodiments, the push rod assembly includes a follower wheel connected to the push shaft, the follower wheel being used to abut against the fourth inclined surface. Thus, the follower wheel abuts against the fourth inclined surface, reducing the risk of damage to the push shaft and / or mating parts due to excessive friction during contact with the fourth inclined surface, and improving the service life of the transfer tooling, etc.

[0023] In some embodiments, the push rod assembly includes a third elastic element, and the push shaft includes a flange portion. The third elastic element is elastically supported between the flange portion and the follower wheel. Thus, the elastic support of the third elastic element between the flange portion and the follower wheel facilitates the push shaft's repositioning after abutting against the fourth inclined surface in the first direction, improving the transport efficiency of the sleeve to be transported and the reliability of the transport process.

[0024] In some embodiments, the push rod assembly includes a push shaft sleeve connected to the transfer body. The push shaft sleeve has a guide hole extending along a first direction, with a portion of the push shaft located within the guide hole. Thus, the guide hole extending along the first direction and the portion of the push shaft located within it facilitates guiding the push shaft to move in the first direction, making efficient use of the internal space of the transfer body, reducing the volume of the transfer fixture, and improving the compactness of the transfer fixture.

[0025] In some embodiments, the transfer fixture further includes a rotating body connected to the transfer body, with at least a portion of the rotating body protruding from the outer surface of the transfer body. Thus, the rotation of the rotating body assists the movement of the sleeve to be transferred between the feed end and the transfer shaft, improving the transfer efficiency of the sleeve.

[0026] In some embodiments, the side wall of the transfer body is provided with an assembly hole, and the transfer tooling also includes a fixed shaft. The rotating body portion is located within the assembly hole, the fixed shaft passes through the rotating body, and the rotating body is connected to the transfer body through the fixed shaft. The rotating body can rotate around the fixed shaft. Thus, the rotating body portion is located within the assembly hole, and the rotating body can rotate around the fixed shaft, allowing the rotating body to be connected to the transfer body through a simple product structure, reducing the volume of the transfer tooling, and improving the compactness of the transfer tooling.

[0027] To address the aforementioned issues, this application provides a battery production system, which includes the aforementioned transfer fixture. Attached Figure Description

[0053] Energy conservation and emission reduction are key to sustainable development, which in turn promotes the adjustment of the energy structure and drives the development and application of battery technology. The key to the development of battery technology lies in electrochemical energy storage technology. Due to its advantages such as high energy density, good cycle capability, high operating voltage, environmental friendliness, and low self-discharge, it has been widely used in portable electronics, electric vehicles, and energy storage systems.

[0054] A complete battery production process requires numerous production steps, each consisting of an independent piece of equipment. After completing a step, the product must be transferred to the next step's equipment. However, during the transfer process, problems such as products detaching from the transfer equipment and being damaged can easily occur.

[0055] To address the technical problems existing in related technologies, this application provides a transfer fixture and a battery production system. The transfer fixture may include a transfer body and a limiting module. The transfer body is used to mount the sleeve to be transported. The limiting module fixes the sleeve mounted on the transfer body to the transfer body, thereby reducing the risk of the sleeve accidentally detaching from the transfer fixture and improving the transfer efficiency and reliability of the transfer process.

[0056] Specifically, this application provides a battery production system, which includes a transfer fixture. The battery production system may include, but is not limited to, stirring equipment, coating equipment, rolling equipment, die-cutting equipment, baking equipment, winding equipment, stacking equipment, tab welding equipment, casing equipment, electrolyte injection equipment, etc. The transfer fixture can transfer sleeves to be transported between various devices. For example, the transfer fixture can transfer sleeves without wound electrodes from one device to a winding device, allowing the winding device to wind the electrodes onto the sleeves. The transfer fixture can also transfer sleeves with wound electrodes from the winding device to a stacking device, etc. The sleeves to be transported can be of any cylindrical structure. For example, a sleeve may include a main body and two disc-shaped parts, with the two disc-shaped parts connected to both ends of the main body. The radial dimension of the two disc-shaped parts is larger than the radial dimension of the main body, allowing objects such as electrodes to be wound and disposed on the main body of the sleeve.

[0057] See Figures 1 to 3 , Figure 1 This is a first-view structural schematic diagram of a transfer tooling fitted with a sleeve to be transported according to one or more embodiments of this application. Figure 2 This is a second-view structural schematic diagram of a transfer tooling fitted with a sleeve to be transported according to one or more embodiments of this application. Figure 3 This is a schematic diagram of the structure of a transfer tooling with the limiting part in the first position according to one or more embodiments of this application.

[0058] The transfer fixture 1 includes a transfer body 10 and a limiting module 20. The transfer body 10 extends along a first direction X and includes an inlet end 11 and a transfer shaft 12. The transfer shaft 12 is used to fit the sleeve 2 to be transferred. The limiting module 20 includes a transmission component 21 and a limiting part 22. The limiting part 22 is connected to the transmission component 21. The transmission component 21 is used to drive the limiting part 22 to move to a first position in a second direction Y that intersects with the first direction X, so that the limiting part 22 stops the sleeve 2 to be transferred from the inlet end 11 along the first direction X from the transfer shaft 12.

[0059] The shape of the transfer body 10 can be set according to actual conditions. For example, the transfer body 10 can be cylindrical and extend along a first direction X. The first direction X can be the length direction of the transfer body 10, or the first direction X can be the axial direction of the transfer body 10. One end of the transfer body 10 in the first direction X can be defined as the inlet end 11. The sleeve 2 to be transferred can be fitted into the transfer body 10 from the inlet end 11, or detached from the transfer body 10 from the inlet end 11. The transfer body 10 can be arranged in multiple segments along the first direction X. One segment can be defined as the transfer shaft 12 of the transfer body 10. The transfer shaft 12 can be a segment close to the inlet end 11, or there can be other segments between the transfer shaft 12 and the inlet end 11, that is, the transfer shaft 12 and the inlet end 11 are spaced apart. Other mechanisms can be installed on the end of the transfer shaft 12 away from the inlet end 11 so that the sleeve 2 to be transferred fitted onto the transfer shaft 12 cannot detach from the transfer shaft 12 from the side of the transfer shaft 12 away from the inlet end 11. For example, a tensioning mechanism can be installed at the end of the transfer shaft 12 away from the feed end 11. The radial dimension of the transfer shaft 12 can be changed by the tensioning mechanism so that the sleeve to be transported 2 can be fixed or detached from the transfer shaft 12. For example, when the sleeve to be transported 2 is sleeved on the outside of the transfer shaft 12, the radial dimension of the transfer shaft 12 can be increased so that the outer wall of the transfer shaft 12 is in close contact with the inner wall of the sleeve to be transported 2, thereby achieving the inner clamping and fixing of the sleeve to be transported 2. When the sleeve to be transported 2 needs to move in the first direction X, the radial dimension of the transfer shaft 12 can be reduced by the tensioning mechanism so that the hole diameter of the sleeve to be transported 2 is larger than the outer diameter of the transfer shaft 12.

[0060] The limiting module 20 includes a transmission component 21 and a limiting part 22. The transmission component 21 can drive the limiting part 22 to move in the second direction Y. When the limiting part 22 moves to the first position, the limiting part 22 can be located between the feed end 11 and the transfer shaft 12, so that the limiting part 22 can stop the sleeve 2 to be moved out of the feed end 11 from the transfer shaft 12 along the first direction X. For example, in the first position, the limiting part 22 can contact and protrude from the outer surface of the transfer body 10, or the limiting part 22 can have a gap with the outer surface of the transfer body 10, as long as the position and state of the limiting part 22 can stop the sleeve 2 to be moved out of the feed end 11 from the transfer shaft 12 along the first direction X.

[0061] The shape and position of the transmission component 21 can be set according to the actual situation. For example, the transmission component 21 can be located inside the transfer body 10 as a whole. The transmission component 21 is connected to the limiting part 22. The transmission component 21 can move the limiting part 22 to a first position that protrudes from the outer wall surface of the transfer body 10. The limiting part 22 can then stop the sleeve 2 to be moved out of the feed end 11 from the transfer shaft 12 along the first direction X at the first position. For example, the transmission assembly 21 can be located entirely outside the transfer body 10. The transmission assembly 21 can be connected to the side of the transfer shaft 12 away from the feed end 11. The transmission assembly 21 is spaced apart from the transfer body 10 in the second direction Y, so that the transmission assembly 21 does not interfere with the sleeve 2 to be transported. The transmission assembly 21 can extend along the first direction X to the space between the feed end 11 and the transfer shaft 12. The limiting part 22 is connected to the transmission assembly 21. The transmission assembly 21 can drive the limiting part 22 to move in the second direction Y to approach the transfer body 10 to the first position. At the first position, the limiting part 22 can stop the sleeve 2 to be transported from the feed end 11 of the transfer shaft 12 along the first direction X. Alternatively, the transmission assembly 21 can be located entirely outside the transfer body 10. The transmission assembly 21 can be connected to the feed end 11 of the transfer shaft 12. It is only necessary to ensure that the transmission assembly 21 does not interfere with the sleeve 2 to be transported during the process of the sleeve to be transported entering the transfer body 10 from the feed end 11. The first direction X and the second direction Y can be perpendicular to each other. The first direction X can be the axial direction of the transfer body 10, and the second direction Y can be the radial direction of the transfer body 10.

[0062] Through the above implementation method, the transmission component 21 is used to drive the limiting part 22 to move to the first position in the second direction Y. The limiting part 22 can stop the sleeve 2 to be transported from the feed end 11 of the transfer shaft 12 along the first direction X by stopping it at the first position. This reduces the risk of the sleeve 2 accidentally falling off the transfer tooling 1, and improves the transfer efficiency and reliability of the transfer process of the sleeve 2.

[0063] See Figures 1 to 6 , Figure 4 This is a schematic diagram of the structure of the transfer tooling according to one or more embodiments of this application, showing the limiting part in the second position. Figure 5 yes Figure 3 The diagram shows the disassembled structure of the transfer tooling. Figure 6 This is a schematic diagram of the structure of a portion of the transport body according to one or more embodiments of this application.

[0064] The transfer body 10 has an internal mounting cavity 13. The side wall of the mounting cavity 13 has a first through hole 131 extending along a second direction Y intersecting the first direction X. The first through hole 131 is located between the feed end 11 and the transfer shaft 12 in the first direction X. A transmission assembly 21 is disposed within the mounting cavity 13 and connected to the transfer body 10. A limiting part 22 corresponds to the first through hole 131 in the second direction Y. At a first position, the limiting part 22 protrudes from the outer surface of the transfer body 10 in the second direction Y. The shape and structure of the mounting cavity 13 can be set according to actual conditions. For example, the mounting cavity 13 can be cylindrical. The transmission assembly 21 can be located within the mounting cavity 13 and fixedly connected to the inner side wall of the mounting cavity 13, so that the transmission assembly 21 can maintain a relatively fixed state with the transfer body 10. By rationally utilizing the internal space of the transfer body 10, the volume of the transfer fixture 1 is reduced, and the compactness of the transfer fixture 1 is improved. The first through hole 131 can penetrate the opposite surfaces of the sidewall of the mounting cavity 13, so that the mounting cavity 13 can communicate with the outside through the first through hole 131. The shape of the first through hole 131 can match the shape of the limiting part 22, and the size of the first through hole 131 can be slightly larger than the size of the limiting part 22. The limiting part 22 corresponds to the first through hole 131 in the second direction Y. The transmission assembly 21 can drive the limiting part 22 to move in the second direction Y, thereby allowing the limiting part 22 to pass through the first through hole 131 and move to the desired position. Figure 3 The first position protruding from the outer surface of the transfer body 10 is shown, and the first through hole 131 is located between the feed end 11 and the transfer shaft 12 in the first direction X. When the limiting part 22 is in the first position, the limiting part 22 can stop the sleeve to be transported 2 from moving out of the feed end 11 from the transfer shaft 12 along the first direction X, further reducing the risk of the sleeve to be transported 2 accidentally falling off the transfer tooling 1, improving the transfer efficiency of the sleeve to be transported 2 and the reliability of the transfer process.

[0065] The transmission assembly 21 is also used to drive the limiting part 22 to move in the second direction Y, so that the limiting part 22 moves from the first position to the second position where it does not protrude from the outer surface of the transfer body 10. In some applications, when it is necessary to fit the sleeve 2 to be transported from the feed end 11 onto the transfer shaft 12, the transmission assembly 21 can be used to keep the limiting part 22 in such a position. Figure 4 The second position shown does not protrude from the outer surface of the transfer body 10. After the sleeve to be transported 2 is fitted onto the outer side of the transfer shaft 12, the transmission assembly 21 then drives the limiting part 22 to move along the second direction Y to the position shown. Figure 3 As shown in the first position, the stop sleeve 2 is moved out of the feed end 11 from the transfer shaft 12 along the first direction X. When it is necessary to move the sleeve 2 located on the transfer shaft 12 out of the transfer shaft 12, the transmission assembly 21 can drive the limiting part 22 to move along the second direction Y to the position shown. Figure 4The second position shown facilitates the removal of the sleeve 2 to be transported from the feed end 11 from the transfer shaft 12. This reduces the interference of the limiting part 22 with the movement of the sleeve 2 from the feed end 11 along the first direction X to the transfer body 10, thereby improving the transfer efficiency of the sleeve 2.

[0066] The limiting part 22 is provided with a stop surface 221 and a first inclined surface 222. The stop surface 221 faces the transfer shaft 12, and the first inclined surface 222 is located on the side of the limiting part 22 away from the transmission assembly 21. The first inclined surface 222 is inclined relative to the first direction X, and the first inclined surface 222 and the stop surface 221 face opposite directions. Figure 3 As shown, the first inclined surface 222 is located on the side of the limiting part 22 away from the transmission assembly 21, that is, the first inclined surface 222 is inclined relative to the first direction X. When the limiting part 22 is in the first position, the first inclined surface 222 can face away from the transfer body 10. In some application scenarios, when it is necessary to put the sleeve 2 to be transported from the feed end 11 onto the transfer shaft 12, the limiting part 22 can be in the position as follows: Figure 3 As shown in the first position, during the continuous movement of the sleeve 2 from the feed end 11 towards the transfer shaft 12 along the first direction X, the sleeve 2 preferentially abuts against the first inclined surface 222, causing the limiting part 22 to gradually transfer along the second direction Y to the position shown. Figure 4 The second position shown continues until the sleeve 2 to be transported is fitted onto the outside of the transfer shaft 12, after which the transmission assembly 21 drives the limiting part 22 to move along the second direction Y to the position shown. Figure 3 The first position shown can reduce the interference of the limiting part 22 with the movement of the sleeve 2 from the feed end 11 along the first direction X to the transfer body 10 by the design of the first inclined surface 222, thereby improving the transfer efficiency of the sleeve 2. The stop surface 221 can be perpendicular to the first direction X, or when the limiting part 22 is in the first position, the stop surface 221 can face the transfer body 10. When the sleeve 2 is sleeved on the outside of the transfer shaft 12 and the limiting part 22 is in the first position, the stop surface 221 stops the sleeve 2 from moving out of the feed end 11 along the first direction X from the transfer shaft 12, thereby reducing the risk of the sleeve 2 accidentally falling off the transfer fixture 1.

[0067] In some embodiments, the transfer fixture 1 further includes a rotating body 40 connected to the transfer body 10, with at least a portion of the rotating body 40 protruding from the outer surface of the transfer body 10. The rotating body 40 may include, but is not limited to, a bearing 30 or a ball bearing, etc. The rotating body 40 is capable of rotation, and it may be spaced circumferentially from the limiting portion 22 located in the first position, such as... Figure 2As shown, the limiting part 22 in the first position is located on the top surface of the transfer shaft 12 in the direction of gravity, and the rotating body 40 is located on the adjacent side of the transfer shaft 12. The number of rotating bodies 40 can be set according to the actual situation, for example, there can be one, two, three or other numbers of rotating bodies 40. In some application scenarios, during the process of putting the sleeve 2 to be transported from the feed end 11 to the transfer shaft 12 along the first direction X, or during the process of moving the sleeve 2 to be transported from the transfer shaft 12 to the feed end 11 along the first direction X, the sleeve 2 to be transported comes into contact with the rotating body 40. The rotation of the rotating body 40 can assist the sleeve 2 to be transported in moving between the feed end 11 and the transfer shaft 12, thereby improving the transfer efficiency of the sleeve 2 to be transported.

[0068] like Figure 3 and Figure 4 As shown, the side wall of the transfer body 10 is provided with an assembly hole 14. The transfer fixture 1 also includes a fixed shaft 50. The rotating body 40 is partially located in the assembly hole 14, and the fixed shaft 50 passes through the rotating body 40. The rotating body 40 is connected to the transfer body 10 through the fixed shaft 50, and the rotating body 40 can rotate around the fixed shaft 50. The assembly hole 14 can be a through hole or a blind hole. The shape of the assembly hole 14 can be set according to the actual situation. For example, the assembly hole 14 can be a circular hole, an oblong hole, a rectangular hole, etc. The rotating body 40 can include a bearing 30. The fixed shaft 50 can be inserted in the middle of the rotating body 40 so that the rotating body 40 can rotate around the fixed shaft 50. The fixed shaft 50 can be detachably connected to the transfer body 10. For example, the fixed shaft 50 can be detachably connected to the transfer body 10 through bolts or buckles, so that the rotating body 40 can be connected to the transfer body 10 through a simple product structure, reducing the volume of the transfer fixture 1 and improving the compactness of the transfer fixture 1. The rotating body 40 is partially located inside the assembly hole 14, and the remaining part of the rotating body 40 is located outside the assembly hole 14 and protrudes from the outer surface of the transfer body 10. This allows the sleeve 2 to be transported to effectively contact the rotating body 40 during the process of fitting the sleeve 2 from the feed end 11 along the first direction X to the transfer shaft 12, or during the process of moving the sleeve 2 from the transfer shaft 12 out of the feed end 11 along the first direction X. The rotation of the rotating body 40 can assist the sleeve 2 to move between the feed end 11 and the transfer shaft 12, thereby improving the transfer efficiency of the sleeve 2.

[0069] In some embodiments, the transmission assembly 21 includes a central support plate 23, a first side plate 24, and a first elastic member 25. The first side plate 24 is connected to the limiting portion 22. The central support plate 23 is spaced apart from the side of the first side plate 24 opposite to the limiting portion 22. The first elastic member 25 is elastically supported between the first side plate 24 and the central support plate 23. The first side plate 24 is used to move with the limiting portion 22 in the second direction Y. The shape and structure of the central support plate 23, the first side plate 24, and the first elastic member 25 can be set according to actual conditions. For example, the central support plate 23 and the first side plate 24 can be flat, and the first elastic member 25 can include, but is not limited to, a spring or a sheet. The central support plate 23 and the first side plate 24 are located within the mounting cavity 13. The central support plate 23 and the first side plate 24 can be arranged opposite to each other and spaced apart in the second direction Y. The first elastic member 25 is elastically supported between the first side plate 24 and the central support plate 23. The first side plate 24 moves with the limiting part 22 in the second direction Y. When the limiting part 22 is in the first position, the first elastic member 25 can be kept slightly compressed or in a natural state between the central support plate 23 and the first side plate 24. During the process of the limiting part 22 moving from the first position to the second position along the second direction Y, the limiting part 22 continuously compresses the first elastic member 25. When the external force applied to the limiting part 22 and / or the first side plate 24 is released, the limiting part 22 can be reset from the second position with the first side plate 24 under the elastic force of the first elastic member 25 and held back to the first position. This further reduces the risk of the sleeve 2 being accidentally detached from the transfer fixture 1, improves the transfer efficiency of the sleeve 2 being transported, and enhances the reliability of the transfer process.

[0070] The limiting module 20 includes a pressing part 26, which is connected to the limiting part 22 via a transmission assembly 21. The transmission assembly 21 is configured to allow the limiting part 22 and the pressing part 26 to move relative to each other or in opposite directions in the second direction Y. The shape of the pressing part 26 can be set according to actual conditions. The pressing part 26 and the transmission assembly 21 can be continuously held within the mounting cavity 13. Pressure can be applied to the pressing part 26 within the mounting cavity 13, causing the pressing part 26 to move in the second direction Y. Alternatively, when the limiting part 22 is in the first position, the pressing part 26 can be partially located outside the mounting cavity 13. When the limiting part 22 is in the second position, the pressing part 26 can be completely located inside the mounting cavity 13. When the pressing part 26 is located outside the mounting cavity 13, an external force can be applied to the pressing part 26. The transmission assembly 21 is configured such that the limiting part 22 and the pressing part 26 move relative to each other or in opposite directions in the second direction Y. This allows the limiting part 22 to move along with the pressing part 26 in the second direction Y by applying an external force along the second direction Y to the pressing part 26. This facilitates the limiting part 22 stopping the sleeve 2 to be transported from the feed end 11 of the transfer shaft 12 in the first position, and also facilitates the sleeve 2 to be transported from the feed end 11 of the transfer shaft 12 or from the feed end 11 to the transfer shaft 12 in the second position. This improves the transport efficiency of the sleeve 2 and the reliability of the transport process.

[0071] The side wall of the transfer body 10 is provided with a second through hole 132, which extends along the second direction Y. The first through hole 131 and the second through hole 132 are located on opposite sides of the mounting cavity 13 in the second direction Y. The pressing part 26 corresponds to the second through hole 132 in the second direction Y. When the limiting part 22 is in the first position, the pressing part 26 protrudes from the outer surface of the transfer body 10 in the second direction Y. When the limiting part 22 is in the second position, the pressing part 26 does not protrude from the outer surface of the transfer body 10 in the second direction Y. The second through hole 132 can penetrate the opposite surfaces of the sidewall of the mounting cavity 13, so that the mounting cavity 13 can communicate with the outside through the second through hole 132. The shape of the second through hole 132 can match the shape of the pressing part 26, and the size of the second through hole 132 can be slightly larger than the size of the pressing part 26. The pressing part 26 corresponds to the second through hole 132 in the second direction Y. The transmission assembly 21 can drive the pressing part 26 to move in the second direction Y, so that the pressing part 26 can pass through the second through hole 132 to move to the desired position. Figure 3 The position shown is protruding from the outer surface of the transfer body 10. The first through hole 131 and the second through hole 132 are located on opposite sides of the mounting cavity 13 in the second direction Y. In some applications, when it is necessary to put the sleeve 2 to be transported onto the transfer shaft 12 from the feed end 11, or to remove it from the transfer shaft 12 from the feed end 11, pressure can be applied to the pressing part 26 so that the pressing part 26 and the limiting part 22 are held in a certain position. Figure 4As shown, the position where it does not protrude from the outer surface of the transfer body 10 is such that the limiting part 22 is in the second position. Until the sleeve to be transported 2 is fitted onto the outside of the transfer shaft 12 or the sleeve to be transported 2 is moved out of the transfer shaft 12, the pressure applied to the pressing part 26 is released. Under the action of the transmission assembly 21, the pressing part 26 and the limiting part 22 move in opposite directions along the second direction Y, so that the pressing part 26 and the limiting part 22 are held in the same position. Figure 3 The position shown does not protrude from the outer surface of the transfer body 10, which improves the transfer efficiency of the sleeve 2 to be transported and the reliability of the transfer process.

[0072] In some embodiments, the limiting module 20 includes a central support plate 23, a second side plate 34, and a second elastic member 35. The second side plate 34 is connected to the pressing part 26. The central support plate 23 is spaced apart from the side of the second side plate 34 facing away from the pressing part 26. The second elastic member 35 is elastically supported between the second side plate 34 and the central support plate 23. The second side plate 34 is used to move with the pressing part 26 in the second direction Y. The shape and structure of the central support plate 23, the second side plate 34, and the second elastic member 35 can be set according to actual conditions. For example, the central support plate 23 and the second side plate 34 can be flat. The second elastic member 35 can be, but is not limited to, a spring or a sheet. The central support plate 23 and the second side plate 34 are located in the mounting cavity 13. The central support plate 23 and the second side plate 34 can be arranged opposite to each other and spaced apart in the second direction Y. The second elastic member 35 is elastically supported between the second side plate 34 and the central support plate 23. The second side plate 34 moves with the pressing part 26 in the second direction Y. When the pressing part 26 is in a position protruding from the outer surface of the transfer body 10, the second elastic member 35 can be kept slightly compressed or in a natural state between the middle support plate 23 and the second side plate 34. When the pressing part 26 moves along the second direction Y to a position where it does not protrude from the outer surface of the transfer body 10, the pressing part 26 continues to compress the second elastic member 35. When the external force applied to the pressing part 26 and / or the second side plate 34 is released, the pressing part 26 can be reset with the second side plate 34 under the elastic force of the second elastic member 35, so that the limiting part 22 can switch between the first position and the second position through the pressing part 26, thereby improving the transfer efficiency of the sleeve 2 to be transported and the reliability of the transfer process.

[0073] In some embodiments, the pressing portion 26 is provided with a second inclined surface 261 and a third inclined surface 262, which are located on the side of the limiting portion 22 away from the transmission assembly 21. The second inclined surface 261 and the third inclined surface 262 are inclined relative to the first direction X, and their orientations are opposite. Figure 3As shown, the second inclined surface 261 and the third inclined surface 262 are located on the side of the limiting part 22 away from the transmission assembly 21. When the limiting part 22 is in the first position, the second inclined surface 261 and the third inclined surface 262 can face away from the transfer body 10. In some application scenarios, when it is necessary to put the sleeve 2 to be transported from the feed end 11 onto the transfer shaft 12, the limiting part 22 and the pressing part 26 can be in the following position: Figure 3 As shown, during the continuous movement of the sleeve 2 from the feed end 11 towards the transfer shaft 12 along the first direction X, the sleeve 2 preferentially abuts against the second inclined surface 261, causing the limiting part 22 and the pressing part 26 to gradually transfer along the second direction Y to the position shown. Figure 4 As shown in the figure, after the sleeve 2 to be transported is fitted onto the outside of the transfer shaft 12, the transmission assembly 21 then drives the limiting part 22 and the pressing part 26 to move along the second direction Y to the position shown in the figure. Figure 3 As shown, the design of the second inclined surface 261 can reduce the interference between the limiting part 22 and the pressing part 26 on the movement of the sleeve 2 to be transported from the feed end 11 along the first direction X to the transfer body 10, thereby improving the transfer efficiency of the sleeve 2 to be transported.

[0074] In some application scenarios, such as Figure 2 As shown, the inner diameter of the sleeve to be transported 2 can be larger than the inner diameter of the transport body 10. When the sleeve to be transported 2 is sleeved on the transport shaft 12, the top surface of the transport shaft 12 in the gravity direction can abut against the sleeve to be transported 2. At the same time, the limiting part 22 is also located on the top surface side of the transport shaft 12 in the gravity direction, so that the sleeve to be transported 2 can be restricted by the limiting part 22 within the transport shaft 12. Meanwhile, the sleeve to be transported 2 is spaced apart from the pressing part 26. The gap between the sleeve to be transported 2 and the bottom surface of the transport shaft 12 in the gravity direction where the pressing part 26 is located is greater than the height of the pressing part 26 protruding from the bottom surface of the transport shaft 12 in the gravity direction. This reduces the risk that the sleeve to be transported 2 will come into contact with the third inclined surface 262 and detach from the transport shaft 12 during the transport process. When it is necessary to move the sleeve 2 to be transported from the feed end 11 to the transfer shaft 12, the sleeve 2 to be transported can first be supported on a support platform. The sleeve 2 to be transported contacts the bottom surface of the transfer shaft 12, which is provided with the pressing part 26, in the direction of gravity, so that there is a gap between the sleeve 2 to be transported and the top surface of the transfer shaft 12 in the direction of gravity. At this time, as the sleeve 2 to be transported moves from the transfer shaft 12 to the feed end 11 along the first direction X relative to the transfer shaft 12, the sleeve 2 to be transported first abuts against the third inclined surface 262, so that the limiting part 22 and the pressing part 26 gradually transfer along the second direction Y to the feed end 11. Figure 4 The position shown is maintained until the sleeve 2 to be transported is moved out of the transfer shaft 12. The transmission assembly 21 then drives the limiting part 22 and the pressing part 26 to move along the second direction Y to the position shown. Figure 3 The position shown improves the transfer efficiency of the sleeve 2 to be transported and the reliability of the transfer process.

[0075] See further Figures 1 to 10 , Figure 7 This is a schematic diagram of the structure of the transmission assembly connecting the limiting part and the pressing part according to one or more embodiments of this application. Figure 8 yes Figure 7 The diagram shows the disassembled structure of the transmission assembly connecting the limiting part and the pressing part. Figure 9 This is a schematic diagram of the structure of a transmission assembly according to one or more embodiments of this application. Figure 10 This is a schematic diagram of the structure of a rotating sleeve according to one or more embodiments of this application.

[0076] The transmission assembly 21 includes a first guide rod 27, a second guide rod 28, and a rotating sleeve 29. The first guide rod 27 is connected to the side of the limiting part 22 facing the pressing part 26, and the second guide rod 28 is connected to the side of the pressing part 26 facing the limiting part 22. The rotating sleeve 29 is connected to both the first guide rod 27 and the second guide rod 28. One of the first guide rod 27 and the second guide rod 28 is used to move in the second direction Y to drive the rotating sleeve 29 to rotate around the second direction Y. During the rotation of the rotating sleeve 29 around the second direction Y, it drives the other of the first guide rod 27 and the second guide rod 28 to move in the second direction Y. The shape and structure of the first guide rod 27, the second guide rod 28, and the rotating sleeve 29 can be set according to the actual situation. The first guide rod 27 is located in the mounting cavity 13. One end of the first guide rod 27 is connected to the side of the limiting part 22 facing the pressing part 26, and the other end of the first guide rod 27 is displaceably connected to the rotating sleeve 29. The second guide rod 28 is located inside the mounting cavity 13. One end of the second guide rod 28 is connected to the pressing part 26 on the side facing the limiting part 22, and the other end of the second guide rod 28 is displaceably connected to the rotating sleeve 29.

[0077] In some applications, when the limiting part 22 and / or the first side plate 24 are subjected to an external force along the second direction Y, the first guide rod 27 moves in the second direction Y. Simultaneously, during its movement, the first guide rod 27 drives the rotating sleeve 29 to rotate around the second direction Y. During this rotation, the rotating sleeve 29 drives the second guide rod 28 to move relative to or away from the first guide rod 27 in the second direction Y. In other applications, when the pressing part 26 and / or the second side plate 34 are subjected to an external force along the second direction Y, the second guide rod 28 moves in the second direction Y. Simultaneously, during its movement, the second guide rod 28 drives the rotating sleeve 29 to rotate around the second direction Y. During this rotation, the rotating sleeve 29 drives the first guide rod 27 to move relative to or away from the second guide rod 28 in the second direction Y. In still other applications, when the rotating sleeve 29 is subjected to an external force rotating around the second direction Y, during this rotation, the rotating sleeve 29 drives the first guide rod 27 and the second guide rod 28 to move relative to or away from each other in the second direction Y. Therefore, one of the first guide rod 27 and the second guide rod 28 is used to move in the second direction Y to drive the rotating sleeve 29 to rotate around the second direction Y. During the rotation of the rotating sleeve 29 around the second direction Y, it drives the other of the first guide rod 27 and the second guide rod 28 to move in the second direction Y. This achieves relative or opposite movement of the limiting part 22 and the pressing part 26 in the second direction Y through a simple product structure, making reasonable use of the internal space of the transfer body 10, reducing the volume of the transfer tooling 1, and improving the compactness of the transfer tooling 1.

[0078] The sidewall of the rotating sleeve 29 is provided with a first helical groove 291 and a second helical groove 292, the first helical groove 291 and the second helical groove 292 having opposite directions of rotation. The first guide rod 27 includes a first protrusion 271, and the second guide rod 28 includes a second protrusion 281. The first protrusion 271 is disposed in the first helical groove 291, and the second protrusion 281 is disposed in the second helical groove 292. Figure 8 and Figure 9As shown, the first spiral groove 291 can be formed on the side wall of the rotating sleeve 29. One end of the first spiral groove 291 is located at the first end of the rotating sleeve 29 in the second direction Y, and the first spiral groove 291 can gradually extend towards the second end of the rotating sleeve 29 around the second direction Y. The second spiral groove 292 can be formed on the side wall of the rotating sleeve 29. One end of the second spiral groove 292 is located at the second end of the rotating sleeve 29 in the second direction Y, and the second spiral groove 292 can gradually extend towards the first end of the rotating sleeve 29 around the second direction Y. The shapes of the first protrusion 271 and the second protrusion 281 can be set according to the actual situation. The first protrusion 271 can be at least partially located in the first spiral groove 291, and the second protrusion 281 can be at least partially located in the second spiral groove 292. The first spiral groove 291 and the second spiral groove 292 rotate in opposite directions. The first protrusion 271 is disposed in the first spiral groove 291 and the second protrusion 281 is disposed in the second spiral groove 292. The limiting part 22 and the pressing part 26 can move relative to each other or move in opposite directions in the second direction Y through a simpler structure. The internal space of the transfer body 10 is rationally utilized, the volume of the transfer tooling 1 is further reduced, and the compactness of the transfer tooling 1 is improved.

[0079] The first protrusion 271 moves in the second direction Y to drive the rotating sleeve 29 to rotate around the second direction Y via the first helical groove 291. During the rotation of the rotating sleeve 29 around the second direction Y, the second protrusion 281 moves in the second direction Y via the second helical groove 292. Specifically, when the limiting part 22 and / or the first side plate 24 are subjected to an external force along the second direction Y, the first guide rod 27 drives the first protrusion 271 to move in the second direction Y. The sidewall of the first protrusion 271 and the first helical groove 291 abut against each other, causing the rotating sleeve 29 to rotate around the second direction Y. During the rotation of the rotating sleeve 29 around the second direction Y, the sidewall of the second helical groove 292 abuts against the second protrusion 281, causing the second protrusion 281 to move relative to or away from the first protrusion 271 in the second direction Y.

[0080] The second protrusion 281 moves in the second direction Y to drive the rotating sleeve 29 to rotate around the second direction Y via the second spiral groove 292. During the rotation of the rotating sleeve 29 around the second direction Y, the first protrusion 271 moves in the second direction Y via the first spiral groove 291. Specifically, when the pressing part 26 and / or the second side plate 34 are subjected to an external force along the second direction Y, the second guide rod 28 drives the second protrusion 281 to move in the second direction Y. The sidewalls of the second protrusion 281 and the second spiral groove 292 abut against each other, causing the rotating sleeve 29 to rotate around the second direction Y. During the rotation of the rotating sleeve 29 around the second direction Y, the sidewall of the first spiral groove 291 abuts against the first protrusion 271, causing the first protrusion 271 to move relative to or away from the second protrusion 281 in the second direction Y.

[0081] In other application scenarios, when the rotating sleeve 29 is subjected to an external force that rotates about the second direction Y, the sidewalls of the first protrusion 271 and the first spiral groove 291 abut against each other, and the sidewalls of the second protrusion 281 and the second spiral groove 292 abut against each other, so that the first protrusion 271 moves relative to or away from the second protrusion 281 in the second direction Y.

[0082] In some embodiments, the first guide rod 27 further includes a first rod body 272, which extends along the second direction Y and is connected to the limiting part 22 and the first protrusion 271 respectively. The first protrusion 271 protrudes from the side wall of the first rod body 272 in the first direction X. The second guide rod 28 further includes a second rod body 282, which extends along the second direction Y and is connected to the pressing part 26 and the second protrusion 281 respectively. The second protrusion 281 protrudes from the side wall of the second rod body 282 in the second direction Y. The rotating sleeve 29 is provided with a third through hole 293 extending along the second direction Y. The first rod body 272 and the second rod body 282 are at least partially located in the third through hole 293. The shapes and structures of the first rod body 272 and the second rod body 282 can be set according to actual conditions. For example, the first rod body 272 and the second rod body 282 can be cylindrical or prismatic, etc. The first rod body 272 extends along the second direction Y, and the first protrusion 271 can be connected to the end of the first rod body 272 away from the limiting part 22. The first protrusion 271 can protrude from the outer wall of the first rod body 272 in the first direction X. The second rod body 282 extends along the second direction Y, and the second protrusion 281 can be connected to the end of the second rod body 282 away from the pressing part 26. The second protrusion 281 can protrude from the outer wall of the second rod body 282 in the first direction X. The shape and size of the third through hole 293 can match the shape and size of the first rod body 272 and the second rod body 282, allowing the first rod body 272 and the second rod body 282 to move along the second direction Y within the third through hole 293. At the same time, the first protrusion 271 can be disposed in the first spiral groove 291, and the second protrusion 281 can be disposed in the second spiral groove 292. This can reduce the size of the limiting module 20 in the second direction Y, make reasonable use of the internal space of the transfer body 10, further reduce the volume of the transfer fixture 1, and improve the compactness of the transfer fixture 1.

[0083] In some other embodiments, the first rod body 272 and the second rod body 282 may be sleeve-shaped, with the first protrusion 271 protruding from the inner wall of the first rod body 272 and the second protrusion 281 protruding from the inner wall of the second rod body 282. The rotating sleeve 29 may be disposed inside the sleeve of the first rod body 272 and the second rod body 282, so that the first protrusion 271 is disposed in the first spiral groove 291 and the second protrusion 281 is disposed in the second spiral groove 292.

[0084] The limiting module 20 includes a central support plate 23 and a bearing 30. The central support plate 23 has a fourth through hole 231 extending along the second direction Y. The bearing 30 is disposed within the fourth through hole 231 and fixed to the central support plate 23. A rotating sleeve 29 is partially disposed within the bearing 30. The bearing 30 can be fixedly sleeved on the outer wall of the rotating sleeve 29, allowing the rotating sleeve 29 to rotate around the second direction Y with the assistance of the bearing 30. The bearing 30 can be fixedly connected to the central support plate 23. For example, the fourth through hole 231 can be a stepped hole, allowing the bearing 30 to rest on the step of the fourth through hole 231, while other fasteners fix the bearing 30 to the central support plate 23. Alternatively, the fourth through hole 231 can be a linear through hole, allowing other fasteners to be directly fixed to fix the bearing 30 to the central support plate 23. Thus, the bearing 30 can rotate relative to the fixed rotating sleeve 29 and the auxiliary rotating sleeve 29 around the second direction Y, so that the limiting part 22 and the pressing part 26 can move relative to each other or move in opposite directions in the second direction Y through a simple product structure, making reasonable use of the internal space of the transfer body 10, reducing the volume of the transfer tooling 1, and improving the compactness of the transfer tooling 1.

[0085] Furthermore, the limiting module 20 includes a first fixing member 31, which includes a first column 311 and a second column 312. The first column 311 is inserted into the central support plate 23, and the second column 312 is connected to the side of the first column 311 facing the limiting part 22, and abuts against the surface of the bearing 30 facing the limiting part 22. The shape and structure of the first fixing member 31 can be set according to the actual situation, as shown in [reference needed]. Figure 7 and Figure 8 Both the first column 311 and the second column 312 can be cylinders or prisms. The first column 311 can be inserted into the middle support plate 23 near the fourth through hole 231. The second column 312 is connected to the side of the first column 311 facing the limiting part 22, so that the second column 312 abuts against the surface of the bearing 30 facing the limiting part 22. The bearing 30 is fixed from the surface of the bearing 30 facing the limiting part 22 by the first fixing member 31 in cooperation with the middle support plate 23. The first fixing member 31 can be T-shaped, that is, the second column 312 is connected to the end of the first column 311 facing the limiting part 22, and the radial dimension of the first column 311 can be smaller than the radial dimension of the second column 312, so that when the first column 311 is inserted into the middle support plate 23, the second column 312 abuts against the surface of the bearing 30 facing the limiting part 22.

[0086] The limiting module 20 includes a second fixing member 32, which includes a third column 321 and a fourth column 322. The third column 321 is inserted into the central support plate 23, and the fourth column 322 is connected to the side of the third column 321 facing the pressing part 26, and abuts against the surface of the bearing 30 facing the pressing part 26. The shape and structure of the second fixing member 32 can be set according to the actual situation, as shown in [reference]. Figure 7 and Figure 8 Both the third column 321 and the fourth column 322 can be cylinders or prisms. The third column 321 can be inserted into the middle support plate 23 near the fourth through hole 231. The fourth column is connected to the side of the third column 321 facing the pressing part 26, so that the fourth column 322 can abut against the surface of the bearing 30 facing the pressing part 26. The bearing 30 is fixed from the surface of the bearing 30 facing the limiting part 22 by the second fixing member 32 in cooperation with the middle support plate 23. The second fixing member 32 can be T-shaped, that is, the fourth column 322 is connected to the end of the third column 321 facing the limiting part 22, and the radial dimension of the third column 321 can be smaller than the radial dimension of the fourth column 322, so that when the third column 321 is inserted into the middle support plate 23, the fourth column 322 abuts against the surface of the bearing 30 facing the pressing part 26.

[0087] The rotating sleeve 29 includes a first rotating segment 294 and a second rotating segment 295 interconnected in the second direction Y. The first rotating segment 294 is larger in the first direction X than the second rotating segment 295 in the first direction X. The first rotating segment 294 abuts against one side of the bearing 30 in the second direction Y. The second rotating segment 295 is partially disposed inside the bearing 30. A snap-fit ​​ring groove 2951 is provided on the outer periphery of the second rotating segment 295. The limiting module 20 includes a snap-fit ​​member 33, which snaps into the snap-fit ​​ring groove 2951 and abuts against the other side of the bearing 30 in the second direction Y. The larger size of the first rotating segment 294 in the first direction X compared to the second rotating segment 295 in the first direction X allows a step to be formed at the connection between the first rotating segment 294 and the second rotating segment 295. The bearing 30 can be supported on this step, thereby causing the first rotating segment 294 to abut against one side of the bearing 30 in the second direction Y. The shape of the snap-fit ​​groove 2951 can be set according to the actual situation. For example, the snap-fit ​​groove 2951 can be circular or semi-circular, etc. The snap-fit ​​groove 2951 can be spaced apart from the first rotating section 294 in the second direction Y. The bearing 30 can be sleeved between the snap-fit ​​groove 2951 and the first rotating section 294. The snap-fit ​​member 33 can be an annular structure with an opening. The snap-fit ​​member 33 can be snapped into the snap-fit ​​groove 2951 through the opening, and abut against the other side of the bearing 30 and against the side of the middle support plate 23 facing the limiting part 22 in the second direction Y. This achieves the fixation of the bearing 30 and the rotating sleeve 29 through a simple structure, makes reasonable use of the internal space of the transfer body 10, reduces the volume of the transfer tooling 1, and improves the compactness of the transfer tooling 1.

[0088] See Figures 1 to 11 , Figure 11 This is a schematic diagram of the structure of the push rod assembly 36 according to one or more embodiments of this application.

[0089] The limiting module 20 includes a push rod assembly 36, which applies an external force along the second direction Y to the transmission assembly 21, causing the transmission assembly 21 to move the limiting part 22 in the second direction Y. For example, the push rod assembly 36 can directly abut against the transmission assembly 21 along the second direction Y to apply an external force along the second direction Y to the transmission assembly 21, or the push rod assembly 36 can abut against the transmission assembly 21 from other directions, thereby causing the transmission assembly 21 to be subjected to a component force in the second direction Y through the shape and positional relationship between the transmission assembly 21 and the push rod assembly 36. After the push rod assembly 36 applies an external force along the second direction Y to the transmission assembly 21, the transmission assembly 21 can drive the limiting part 22 to move in the second direction Y, improving the transfer efficiency of the sleeve 2 to be transported and the reliability of the transfer process.

[0090] In some embodiments, the transmission assembly 21 includes a central support plate 23, a first side plate 24, and a first elastic member 25. The first side plate 24 is connected to the limiting portion 22. The central support plate 23 is spaced apart from the side of the first side plate 24 opposite to the limiting portion 22. The first side plate 24 includes a plate body 241 and a mating portion 242, which are connected. The plate body 241 is connected to the limiting portion 22. The first elastic member 25 is elastically supported between the plate body 241 and the central support plate 23. The push rod assembly 36 is used to apply an external force along the second direction Y to the mating portion 242. The plate body 241 may be flat, and the mating portion 242 may be connected to the side of the plate body 241. The first elastic member 25 is elastically supported between the plate body 241 and the central support plate 23, and pressure can be applied to the first elastic member 25 through the plate body 241. The push rod assembly 36 can be connected to the transfer body 10. The push rod assembly 36 can abut against the mating part 242 to apply an external force along the second direction Y to the mating part 242. For example, the push rod assembly 36 can directly abut against the mating part 242 along the second direction Y to apply an external force along the second direction Y to the mating part 242, or the push rod assembly 36 can abut against the mating part 242 from other directions. Thus, through the shape and positional relationship between the mating part 242 and the push rod assembly 36, the mating part 242 is subjected to a component force along the second direction Y. After the push rod assembly 36 applies an external force along the second direction Y to the mating part 242, the mating part 242 can drive the plate body 241 and the limiting part 22 to move in the second direction Y, so that the limiting part 22 can switch between a first position and a second position, thereby improving the transfer efficiency of the sleeve 2 to be transported and the reliability of the transfer process.

[0091] The push rod assembly 36 includes a push shaft 361, which is inserted into the feed end 11 and extends along a first direction X. The mating part 242 includes a fourth inclined surface 243 facing the push shaft 361. The push shaft 361 is used to move along the first direction X and abut against the fourth inclined surface 243. The push shaft 361 may be rod-shaped and extends along the first direction X. The push shaft 361 can be inserted into the feed end 11 and simultaneously exposed inside and outside the mounting cavity 13 to facilitate the application of external force to the push shaft 361 from outside the mounting cavity 13. The fourth inclined surface 243 can be tilted relative to the first direction X. The fourth inclined surface 243 can face the top shaft 361 and the limiting part 22. The top shaft 361 moves along the first direction X and into the mounting cavity 13 to abut against the fourth inclined surface 243. The external force applied by the top shaft 361 to the mating part 242 along the first direction X can be converted into an external force along the second direction Y through the fourth inclined surface 243. This allows the limiting part 22 to move in the second direction Y through a simple product structure, making reasonable use of the internal space of the transfer body 10, reducing the volume of the transfer tooling 1, and improving the compactness of the transfer tooling 1. In some application scenarios, the feed end 11 can dock with other equipment. During docking, other equipment presses the top shaft 361, causing the top shaft 361 to gradually move into the mounting cavity 13 along the first direction X to abut against the mating part 242. This causes the limiting part 22 to move with the plate body 241 to the second position along the second direction Y. In this state, the sleeve 2 to be transported on other equipment can be moved along the first direction X to the transfer shaft 12, or the sleeve 2 to be transported on the transfer shaft 12 can be moved to other equipment through the feed end 11. After the abutment state between the feed end 11 and other equipment is released, the plate body 241, under the action of the first elastic member 25, drives the mating part 242 to reset, thereby driving the top shaft 361 to gradually move out of the mounting cavity 13 along the first direction X. At the same time, the limiting part 22 moves with the plate body 241 from the second position to the first position. The feed end 11 may also be provided with a docking structure, through which the transfer body 10 can dock with other equipment. For example, the docking structure may include, but is not limited to, docking protrusions, docking grooves and / or positioning pins.

[0092] The push rod assembly 36 includes a follower wheel 362, which is connected to the push shaft 361. The follower wheel 362 is used to abut against the fourth inclined surface 243. Figure 11 As shown, the follower wheel 362 can rotate. For example, the follower wheel 362 can be, but is not limited to, a bearing 30 or a ball bearing. The follower wheel 362 is used to abut against the fourth inclined surface 243. During the process of the follower wheel 362 abutting against the fourth inclined surface 243 and continuing to move along the first direction X with the top shaft 361, the rotation of the follower wheel 362 can reduce the risk of damage to the top shaft 361 and / or the mating part 242 due to large-scale friction when abutting against the fourth inclined surface 243, and improve the service life of the transfer tooling 1.

[0093] The push rod assembly 36 includes a third elastic element 363, and the push shaft 361 includes a flange portion 364. The third elastic element 363 is elastically supported between the flange portion 364 and the follower wheel 362. The flange portion 364 may include, but is not limited to, an annular structure, and the flange portion 364 may protrude from the outer surface of the push shaft 361. The follower wheel 362 can be connected to the push shaft 361 via a connecting shaft, which may protrude from the outer surface of the push shaft 361. The third elastic element 363 elastically supports the flange portion 364 and the connecting shaft, facilitating the push shaft 361 to return to its original position after abutting against the fourth inclined surface 243 in the first direction X, thereby improving the transfer efficiency of the sleeve 2 to be transported and the reliability of the transfer process.

[0094] The push rod assembly 36 includes a push shaft sleeve 365, which is connected to the transfer body 10. The push shaft sleeve 365 has a guide hole 3651, which extends along the first direction X. A portion of the push shaft 361 is located within the guide hole 3651. The size and shape of the guide hole 3651 can match the size and shape of the push shaft 361, allowing a portion of the push shaft 361 to move within the guide hole 3651 along the first direction X. The side wall of the guide hole 3651 may also have a side opening, which communicates with the guide hole 3651. The side opening allows the follower wheel 362 to extend to the outside of the guide hole 3651, facilitating contact between the follower wheel 362 and the fourth inclined surface 243. Thus, the push shaft 361 can be guided to move along the first direction X through the guide hole 3651, making efficient use of the internal space of the transfer body 10, reducing the volume of the transfer fixture 1, and improving the compactness of the transfer fixture 1.

[0095] In summary, the transfer fixture 1 provided in this application can be used to transport the sleeve 2 to be transported. In some application scenarios, it connects with other equipment through the inlet end 11. During the connection process, the other equipment presses the top shaft 361, and the top shaft 361 gradually moves into the mounting cavity 13 along the first direction X to abut against the mating part 242. This causes the limiting part 22 to move with the plate body 241 to the second position in the second direction Y. The pressing part 26 can also move synchronously with the limiting part 22 in the second direction Y through the transmission assembly 21 to a position that does not protrude from the outer wall surface of the transfer body 10. In this state, the sleeve 2 to be transported on other equipment can be moved to the transfer shaft 12 along the first direction X, or the sleeve 2 to be transported on the transfer shaft 12 can be moved to other equipment through the inlet end 11. In other application scenarios, the inner diameter of the sleeve to be transported 2 can be larger than the inner diameter of the transport body 10. When the sleeve to be transported 2 is sleeved on the transport shaft 12, the top surface of the transport shaft 12 in the gravity direction can abut against the sleeve to be transported 2. At the same time, the limiting part 22 is also located on the top surface side of the transport shaft 12 in the gravity direction, so that the sleeve to be transported 2 can be restricted by the limiting part 22 within the transport shaft 12. Meanwhile, the sleeve to be transported 2 is spaced apart from the pressing part 26. The gap between the sleeve to be transported 2 and the bottom surface of the transport shaft 12 in the gravity direction where the pressing part 26 is located is greater than the height of the pressing part 26 protruding from the bottom surface of the transport shaft 12 in the gravity direction. This reduces the risk that the sleeve to be transported 2 will come into contact with the third inclined surface 262 and detach from the transport shaft 12 during the transport of the sleeve to be transported. When it is necessary to move the sleeve 2 to be transported from the feed end 11 to the transfer shaft 12, the sleeve 2 to be transported can first be supported on a support platform. The sleeve 2 to be transported contacts the bottom surface of the transfer shaft 12, which is provided with the pressing part 26, in the direction of gravity, so that there is a gap between the sleeve 2 to be transported and the top surface of the transfer shaft 12 in the direction of gravity. At this time, as the sleeve 2 to be transported moves from the transfer shaft 12 to the feed end 11 along the first direction X relative to the transfer shaft 12, the sleeve 2 to be transported preferentially abuts against the third inclined surface 262 of the pressing part 26, so that the limited The positioning part 22 and the pressing part 26 gradually move along the second direction Y to a position that does not protrude from the outer side wall of the transfer body 10 until the sleeve to be transported 2 is moved out of the transfer shaft 12. The transmission assembly 21 then drives the limiting part 22 and the pressing part 26 to move along the second direction Y to a position that protrudes from the transfer body 10, thereby improving the transfer efficiency of the sleeve to be transported 2 and the reliability of the transfer process. During the movement of the limiting part 22 and the pressing part 26, the plate body 241 and the top shaft 361 cooperate to drive the top shaft 361 to move in the first direction X.
