[0001] This invention relates to the field of battery manufacturing equipment technology, specifically to a repair device, disassembly method, and assembly method for the inflation head of a liquid injection machine fixture. Background Technology

[0002] In the field of mechanical manufacturing technology, liquid injection machine fixtures are common spare parts, mainly used for liquid injection operations on products. Among these devices, the inflation head is a crucial component, responsible for injecting liquid into the product; its structure is as follows... Figure 1 and Figure 2 As shown, the inflation head includes an outer sleeve, an inner sleeve, a push rod, a first sealing ring, and a second sealing ring. During use, the first and second sealing rings will be subject to wear and aging, thus requiring regular maintenance. This not only increases the operating cost of the equipment but also affects production efficiency.

[0003] Current solutions primarily involve replacing the entire inflation head. While this addresses the problem, the high frequency and quantity of replacements lead to significant costs, increasing operational expenses for businesses. Therefore, improving the efficiency and quality of inflation head repair while reducing costs is a pressing issue in this field. Summary of the Invention

The first sealing ring is fitted at the connection between the push rod and the outer sleeve. The second sealing ring is fitted onto the outer sleeve. The rework device includes:

[0006] The base extends along the second direction.

[0007] A fixed rod extends along the first direction.

[0008] A placement platform is provided at intervals from the fixing rod along the second direction and is located on the top of the base. The placement platform extends along a third direction and includes a fixing through hole and a leakage receiving area. The fixing through hole is located at the top of the placement platform and is used to place the inflation head of the liquid injection machine clamp. The leakage receiving area is located at the bottom of the fixing through hole, and the first direction, the second direction, and the third direction are perpendicular to each other.

[0009] A crimping device is spaced apart from the placement platform along the first direction, and one end along the second direction is connected to the fixing rod. The crimping device includes a pressing member and a driving device. The pressing member extends along the first direction and is located at the other end of the crimping device along the second direction, with a pin at its bottom. The pin is correspondingly arranged with the fixing through hole along the first direction. The driving device drives the pressing member to move relative to the placement platform along the first direction, so that the pin is inserted into the internal channel and abuts against the pressing rod, thereby pressing the pressing rod down into the leakage area.

[0010] The present invention provides a repair device for the air-filled head of a liquid injection machine clamp. The device is designed with the structure of the air-filled head of the liquid injection machine clamp in mind, so that the air-filled head of the liquid injection machine clamp is fixed in a fixed through hole at the top of the placement platform. The device drives the top pressing member corresponding to the fixed through hole to move down, so that the ejector pin can push out the ejector rod inside the air-filled head of the liquid injection machine clamp. Then, the various components in the air-filled head of the liquid injection machine clamp can be disassembled. The leakage area is used to store the disassembled parts of the air-filled head of the liquid injection machine clamp.

[0021] The clamping plate assembly includes a first fixing plate and a second fixing plate. Both the first fixing plate and the second fixing plate extend along the first direction and are sequentially arranged along the third direction. Along the third direction, the first fixing plate and the second fixing plate have corresponding bolt fixing holes, allowing the clamping plate assembly to switch between a clamped state and a movable state.

[0022] In some embodiments, the crimping device further includes a threaded rod. The threaded rod extends along the first direction and is disposed at the top of the housing. The top of the threaded rod is connected to the top of the fixing rod. The housing has a threaded hole corresponding to the position of the threaded rod, for suspending the threaded rod and fixing the housing in the clamped state. In the open state, the threaded rod is separated from the housing.

[0023] In some embodiments, in the active state, the crimping device can rotate circumferentially relative to the fixing rod and correspond to the fixing through hole or the mounting groove.

Detailed Implementation

[0043] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0044] refer to Figures 1-4 , Figure 1 A three-dimensional view of the air inflator head 8 of the liquid injection machine clamp; Figure 2 A sectional view of the air inflator head of the liquid injection machine clamp; Figure 3 A perspective view of a repair device 1 for an air-filling head 8 of a liquid injection machine clamp provided in an embodiment of the present invention is shown; Figure 4 This invention illustrates a three-dimensional view of a repair device 1 for an air-filling head 8 of a liquid injection machine clamp, according to an embodiment of the present invention. Figure 2 ,

[0045] like Figures 1 to 4 As shown, the technical solution provided in this application is a repair device 1 for the air filling head 8 of a liquid injection machine clamp, wherein:

[0046] The inflator head 8 of the liquid injection machine clamp includes an outer sleeve, an inner sleeve 81, a push rod 83, a first sealing ring 84, and a second sealing ring 85. The outer sleeve is fitted onto the inner sleeve 81, forming an internal channel 82 extending along a first direction. The push rod 83 extends along the first direction ( Figure 3Extending in the Z direction (as shown), and passing through the internal channel 82, it fixes the outer sleeve and the inner sleeve 81. The first sealing ring 84 is fitted at the connection between the top rod 83 and the outer sleeve. The second sealing ring 85 is fitted on the outer sleeve.

[0047] The repair device 1 for the air-filling head 8 of the liquid injection machine clamp includes: a base 2, a fixing rod 3, a placement platform 4, and a pressing device. The base 2 is positioned along the second direction ( Figure 3 Extending in the X direction, the fixing rod 3 extends along the first direction, and the placement platform 4 and the fixing rod 3 are spaced apart along the second direction, both located on the top of the base 2. The placement platform 4 extends along the third direction (as shown in the X direction). Figure 3 Extending in the Y direction, it includes a fixed through hole 40 and a leakage receiving area 41. The fixed through hole 40 is located at the top of the placement platform 4 and is used to place the air inlet head 8 of the liquid injection machine clamp. The leakage receiving area 41 is located at the bottom of the fixed through hole 40, and the first direction, the second direction, and the third direction are perpendicular to each other.

[0048] The crimping device and the placement platform 4 are spaced apart along a first direction, and one end along a second direction is connected to the fixing rod 3. The crimping device includes a pressing member 50 and a driving device 7. The pressing member 50 extends along the first direction and is located at the other end of the crimping device along the second direction, with a pin 51 at its bottom. The pin 51 and the fixing through hole 40 are correspondingly arranged along the first direction. The driving device 7 is used to drive the pressing member 50 to move relative to the placement platform 4 along the first direction, so that the pin 51 is inserted into the internal channel 82 and abuts against the push rod 83, thereby pressing the push rod 83 down into the leak-receiving area 41.

[0049] The repair device 1 for the injection machine clamp inflation head 8 provided in this application is designed for the structure of the injection machine clamp inflation head 8, so that the injection machine clamp inflation head 8 is fixed by being inserted into the fixing through hole 40 at the top of the placement platform 4. The driving device 7 drives the top pressing member 50 corresponding to the position of the fixing through hole 40 to move down, so that the ejector pin 51 can push out the ejector rod 83 inside the injection machine clamp inflation head 8, and then the various components in the injection machine clamp inflation head 8 can be disassembled. The leakage area 41 is used to store the disassembled parts of the injection machine clamp inflation head 8.

[0050] Compared to the traditional method of replacing the entire inflation head 8 of the injection machine fixture, this method only requires disassembling the inflation head 8 and replacing the first sealing ring 84 and the second sealing ring 85 before reassembling and reuse. This saves time and costs; for example, replacing a single sealing ring costs only 1 yuan, while replacing the entire inflation head 8 costs approximately 40 yuan, thus significantly reducing maintenance costs. Furthermore, this device requires no electrical components and can be used normally in factory workshops or outdoors, demonstrating strong adaptability to various application scenarios and meeting maintenance needs in different environments.

[0051] In some embodiments, reference Figure 3 and Figure 4 The pressing member 50 has a rack 52 on the side facing the fixed rod 3 along the second direction, and the rack 52 extends along the first direction. The driving device 7 includes a transmission bearing 70 and a pressing rod 72.

[0052] The transmission bearing 70 is disposed along the second direction between the pressing member 50 and the fixed rod 3, and is located close to the rack 52. The transmission bearing 70 is provided with an external gear ring 71 that mates with the rack 52.

[0053] The pressure rod 72 is located on one side of the transmission bearing 70 along the second direction and is connected to the shaft of the transmission bearing 70. It is used to drive the transmission bearing 70 to rotate by pressing down the pressure rod 72, so that the external gear ring 71 meshes with the rack 52 and drives the top pressure member 50 to move along the first direction.

[0054] For example, the pressing member 50 is driven indirectly by the meshing of the rack 52 and the transmission bearing 70. The direction of movement is adjusted by the pressure rod 72. For instance, when the pressure rod 72 presses down, it drives the transmission bearing 70 to rotate and mesh with the rack 52, causing the pressing member 50 to press down accordingly. The ejector pin 51 then pushes out the ejector rod 83 in the internal channel 82. Gear meshing drive is a highly efficient transmission method with very stable transmission performance. Unlike belt and chain drives, it does not have the problem of looseness or tightness during operation, nor is it affected by friction like friction drives. Therefore, the transmission performance is very reliable, making it suitable for short-distance, high-accuracy applications like those described in this application.

[0055] In some embodiments, reference Figure 3 and Figure 4 The crimping device also includes a housing 6 and a limiting rod 53. The housing 6 is sleeved on the fixing rod 3 and covers the pressing member 50 and the transmission bearing 70. The two ends of the transmission bearing 70 along a third direction are rotatably connected to the inner wall of the housing 6. The limiting rod 53 extends along a first direction and is located above the housing 6. The top of the limiting rod 53 is connected to the top of the pressing member 50.

[0056] For example, the limiting rod 53 has a certain length. When the pressing member 50 moves downward to perform the pressing action, the limiting rod 53 moves synchronously until the bottom of the limiting rod 53 abuts against the top of the housing 6, stopping the downward movement of the pressing member 50, thereby limiting and protecting the ejector pin 51 and the inflation head 8 of the injection machine fixture. In this application, no specific dimension is specified for the length of the limiting rod 53. This value is related to the model of the inflation head 8 of the injection machine fixture and the length of the ejector pin 51. It is only necessary to ensure that when the limiting rod 53 abuts against the housing 6, the ejector pin 51 has pushed out the ejector rod 83.

[0057] In some embodiments, reference Figure 2 and Figure 3 The placement platform 4 also includes a mounting groove 42. The mounting groove 42 is located on the top of the placement platform 4 and is used to place the air inflator head 8 of the liquid injection machine clamp. The inner sleeve 81 is engaged and fixed with the mounting groove 42.

[0058] For example, in order to improve the actual rework efficiency, the replacement liquid injection machine clamp inflation head 8 is assembled by mounting groove 42, and the mounting groove 42 is used for snap-fit ​​fixation. Subsequently, the liquid injection machine clamp inflation head 8 is pressed and fixed by crimping device, so that the rework device 1 can disassemble the liquid injection machine clamp inflation head 8 and reassemble it into a whole.

[0059] In some embodiments, reference Figure 3 The outer casing 6 has a clamping plate assembly 60 at one end near the fixing rod 3 along the second direction. The clamping plate assembly 60 can switch between a clamped state and a movable state.

[0060] The clamping state includes: the ejector pin 51 corresponds to the fixing through hole 40 or the mounting groove 42, and the clamping plate assembly 60 clamps the fixing rod 3.

[0061] The active states include: the clamping plate assembly 60 is not clamping the fixing rod 3, and the crimping device can be positioned relative to the fixing rod 3 circumferentially ( Figure 4 (as shown in the θ direction) and / or the first direction, moving circumferentially around the first direction.

[0062] The clamping plate assembly 60 includes a first fixing plate 61 and a second fixing plate 62. Both the first fixing plate 61 and the second fixing plate 62 extend along a first direction and are arranged sequentially along a third direction. Along the third direction, the first fixing plate 61 and the second fixing plate 62 are provided with corresponding bolt fixing holes 63, which allow the clamping plate assembly 60 to switch between a clamped state and a movable state.

[0063] For example, when the clamping plate assembly 60 is in the active state, the crimping device is moved to the appropriate position, that is, during the disassembly operation, the ejector pin 51 is aligned with the fixing through hole 40; during the assembly operation, the ejector pin 51 is aligned with the mounting groove 42. After the crimping device is adjusted, the device is fixed by the suspension bolt, and the clamping plate assembly 60 is put into the clamped state.

[0064] In some embodiments, reference Figure 3 The crimping device also includes a threaded rod 54. The threaded rod 54 extends along a first direction and is located on the top of the housing 6. The top of the threaded rod 54 is connected to the top of the fixing rod 3. The housing 6 is provided with a threaded hole 64 corresponding to the position of the threaded rod 54, which is used to suspend the threaded rod 54 after the clamping plate assembly 60 clamps the fixing rod 3 in the clamping state, thereby fixing the housing 6 and further strengthening the connection between the crimping device and the fixing rod 3.

[0065] For example, in the active state, the threaded rod 54 is separated from the housing 6, and the bolt in the bolt fixing hole 63 is suspended. The clamping plate assembly 60 is in an active state relative to the fixing rod 3. The crimping device can move relative to the fixing rod 3 in the circumferential direction and / or the first direction. After the movement is completed, the suspended bolt completes the fixation of the device, and the clamping plate assembly 60 is changed to the clamping state.

[0066] In some embodiments, reference Figure 3 In the active state, the crimping device can rotate circumferentially relative to the fixed rod 3 and correspond to the fixed through hole 40 or the mounting groove 42.

[0067] For example, in this device, the movement trajectory of the ejector pin 51 is a fixed circumferential trajectory, so the setting position of the mounting groove 42 needs to be adapted to it so that during the assembly operation, the ejector pin 51 can correspond to the position of the air inflation head 8 of the liquid injection machine clamp in the mounting groove 42.

[0068] refer to Figure 5 , Figure 5 The disassembly procedure for the air inflator head 8 of the liquid injection machine clamp. Figure 1 The specific process is as follows:

[0069] like Figure 5 As shown, the technical solution provided by the present invention also includes a method for disassembling the air inflator 8 of the liquid injection machine clamp, which is used in the rework device 1 described in the above embodiments. The disassembly method includes:

[0070] S1. Provide an air-filling head 8 for a liquid injection machine clamp. The air-filling head 8 for the liquid injection machine clamp includes an outer sleeve, an inner sleeve 81, a top rod 83, a first sealing ring 84, and a second sealing ring 85. The top of the air-filling head 8 for the liquid injection machine clamp is the inner sleeve 81.

[0071] For example, the provided hydraulic clamp inflation head is to be replaced for maintenance. The push rod 83 of the hydraulic clamp inflation head is inserted into the inner channel 82 from the outer sleeve end. Therefore, when performing the disassembly operation, one side of the inner sleeve 81 needs to be aligned with the push pin 51 so that the push pin 51 can push the push rod 83 out along the inner channel 82.

[0072] S2. The bottom of the air-filling head 8 of the liquid injection machine clamp is inserted into the fixed through hole 40, and the outer sleeve is fixed to the placement platform 4.

[0073] For example, the inflation head 8 of the liquid injection machine clamp is partially inserted into the fixed through hole 40, and the inserted part abuts against the hole wall of the fixed through hole 40 to prevent the inflation head 8 of the liquid injection machine clamp from shifting its position in the fixed through hole 40, which would prevent the ejector pin 51 from being accurately positioned with the internal channel 82.

[0074] S3. The driving device 7 drives the pressing member 50 to move relative to the placement platform 4 in the first direction, so that the ejector pin 51 is inserted into the internal channel 82 and abuts against the ejector rod 83, so as to press the ejector rod 83 down into the leakage area 41.

[0075] For example, the downward pressure rod 72, through gear meshing, drives the ejector pin 51 downward, pushing the ejector rod 83 out of the air inlet head 8 of the injection machine fixture. Simultaneously with the movement of the ejector pin 51, the limiting rod 53 moves synchronously, abutting against the outer casing 6 for limiting protection. Furthermore, the leakage collection box 43 can store the separated ejector rod 83, outer sleeve, and inner sleeve 81, and then replace the first sealing ring 84 and the second sealing ring 85.

[0076] refer to Figure 6 , Figure 6 The assembly process of the air inflator head 8 for the liquid injection machine clamp. Figure 2 The specific process is as follows:

[0077] like Figure 5 As shown, the technical solution provided by the present invention also includes a method for assembling the air inflator 8 of the liquid injection machine clamp, which is used in the rework device 1 described in the above embodiments. The assembly method includes:

[0078] S4. Provide an unfastened air-filled head 8 for the liquid injection machine clamp. The air-filled head 8 for the liquid injection machine clamp includes an outer sleeve, an inner sleeve 81, a push rod 83, a first sealing ring 84, and a second sealing ring 85. The bottom of the air-filled head 8 for the liquid injection machine clamp is the inner sleeve 81.

[0079] For example, after the inflation head 8 of the liquid injection machine fixture is disassembled, it is impossible to manually push the push rod 83 completely into the internal channel 82. The disassembly and assembly of the inflation head are achieved simultaneously by the rework device 1, thereby improving the efficiency of the actual rework work. The push rod 83 of the liquid injection machine fixture inflation head is inserted into the internal channel 82 from the outer sleeve end. Therefore, when performing the assembly operation, one side of the outer sleeve needs to be aligned with the push pin 51 so that the push pin 51 can push the push rod 83 into the internal channel 82.

[0080] S5, the inner sleeve 81 is engaged and fixed with the mounting groove 42.

[0081] For example, the inner sleeve 81 is snapped into the mounting groove 42 to prevent the inflation head 8 of the liquid injection machine clamp from shifting in position within the fixed through hole 40, which would prevent the ejector pin 51 from being accurately positioned with the internal channel 82.

[0082] S6. The threaded rod 54 separates from the outer shell 6, the clamping plate assembly 60 switches to the movable state, the crimping device rotates circumferentially until the ejector pin 51 corresponds to the mounting groove 42, the clamping plate assembly 60 switches to the clamping state, and the threaded rod 54 is fixed to the outer shell 6.

[0083] For example, when the hydraulic clamp inflation head is disassembled, the ejector pin 51 corresponds to the fixing through hole 40. Therefore, the position of the ejector pin 51 needs to be adjusted to correspond to the mounting groove 42. Before adjusting the ejector pin 51, the clamping device needs to be separated from the fixing rod 3, that is, the threaded rod 54 and the bolts fixed at the bolt fixing holes 63 of the first fixing plate 61 and the second fixing plate 62 are unscrewed, so that the clamping device can rotate circumferentially. After the ejector pin 51 is aligned with the mounting groove 42, the clamping device needs to be fixed to the fixing rod 3 again, that is, the threaded rod 54 and the fixing bolts at the bolt fixing holes 63 of the first fixing plate 61 and the second fixing plate 62 are screwed in.

[0084] S7. The driving device 7 drives the pressing member 50 to move relative to the placement platform 4 in the first direction, so that the ejector pin 51 is inserted into the internal channel 82 and abuts against the ejector rod 83 until the bottom end of the ejector rod 83 abuts against the outer sleeve.

[0085] For example, the pressing rod 72, through gear meshing, drives the ejector pin 51 to press down, pushing the ejector rod 83 into the internal channel 82 until the bottom end of the ejector rod 83 abuts against the outer sleeve. Simultaneously with the movement of the ejector pin 51, the limiting rod 53 moves synchronously, abutting against the outer casing 6 for limiting protection.

[0086] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, should be included within the protection scope of the present invention.
