Description

Technical Field

[0001] This utility model belongs to the field of automated fluid precision dispensing technology, and in particular relates to a highly adjustable and maintainable rotary dispensing structure. Background Technology

[0002] Moisture-curing sealants (such as polyurethane and MS adhesives) have become core materials in automotive manufacturing (windshield bonding, headliner caulking, and waterproofing of body holes) and new energy batteries (battery pack sealing and cell potting) due to their primer-free bonding and high-elasticity sealing properties. However, existing rotary dispensing equipment faces two technical challenges: (1) Ultra-deep cavity operation: The cavity depth between some battery modules can reach 100-160mm, and there may be interference from flanges or other structures, requiring an increase in the flow channel length and a reduction in the size of the end rotating dispensing structure.

[0003] (2) Irreversible blockage of the flow channel: Because of seal failure during assembly or use, the sealant cures within approximately 30 minutes of exposure to air. Chemical cleaning in a cleanroom environment can easily lead to cell contamination. Currently, the commonly used maintenance method is mechanical peeling. The deep cavity dispensing structure has long and narrow channels, making it difficult to handle and resulting in high maintenance costs.

[0004] Existing technologies are trapped in a vicious cycle of "cleaning-loss-re-cleaning," failing to meet the continuous operation efficiency requirements of industrial production lines. There is an urgent need for a rotary dispensing structure that can operate in ultra-deep cavities and is easy to maintain. Utility Model Content

[0005] This invention provides a height-adjustable and maintainable rotary dispensing structure to solve the problems of poor adaptability of existing rotary dispensing heads in deep cavity operations, difficult and costly maintenance after flow channel blockage. Through modular design and disposable replaceable flow channels, it achieves flexible adjustment of dispensing height, rapid disassembly and assembly of flow channels, and low-cost maintenance, improving the applicability and operating efficiency of the equipment under complex working conditions.

[0006] The technical solution provided by this utility model is as follows: a height-adjustable and maintainable rotary dispensing structure, including a switching valve and a rotary dispensing module, which are fixedly connected by a sliding back plate and a mounting back plate; the dispensing port of the switching valve is fixedly connected to the female port of the two-way valve, the male head of the two-way valve is connected to one end of the tapered external thread of the male Luer connector, and the other end of the male Luer connector is connected to the rotary dispensing module. The rotary dispensing module includes a transmission assembly, a rotating lower end cap, an upper straight-through lock nut connector, a lower straight-through lock nut connector, a vertical fixing rod, a material tube, and an inclined flow channel block; The transmission assembly drives the male Luer joint to rotate; The other end of the male Luer connector is connected to one end of the upper straight-through lock nut connector; the other end of the upper male Luer connector is crimped to one end of the material tube by a lock nut; the other end of the material tube is connected to one end of the lower straight-through lock nut connector by a lock nut; the other end of the lower straight-through lock nut connector is fixed to one end of the inclined flow channel block, and the other end of the inclined flow channel block is connected to the rotating lower end cover; the vertical fixing rod is locked to the rotating lower end cover by screws.

[0007] Preferably, a vertical sleeve is also provided, which is fixed to the mounting back plate, and the lower end of the vertical fixing rod is inserted into the vertical sleeve.

[0008] Preferably, a locking hole is provided on the side wall of the vertical sleeve, and the set screw passes through the locking hole and fits against the outer wall of the vertical fixing rod.

[0009] Preferably, the interior of the vertical fixing rod is hollow.

[0010] Preferably, the inclined flow channel block has an internal channel for glue flow, and the inlet of the flow channel is threaded, so that the inclined flow channel block is threaded to the other end of the lower straight-through lock nut connector.

[0011] Preferably, the interior of the rotating lower end cover is provided with a central through hole, and the outlet of the inclined flow channel block is connected to the central through hole.

[0012] Preferably, the transmission assembly includes a transmission motor, a driving wheel, and a driven wheel; the transmission motor is fixed to the upper end of one side of the mounting back plate, the output shaft of the transmission motor is connected to the shaft of the driving wheel, and the driving wheel and the driven wheel move through a transmission belt.

[0013] Compared to existing technologies, the advantages of this invention are that, by adopting the above solution, it can be applied to dispensing products with a depth of 160-190mm. The portion of the entire flow channel requiring cleaning and maintenance accounts for approximately 58% of the total flow channel (calculated based on a dispensing height of 190mm). The longest cleaning area in the entire flow channel is a 44mm straight-through structure. The disassembly of the disposable flow channel structure can be done using PU or Teflon tubing depending on the fluid properties, and the length can be cut to meet the actual dispensing height requirements, improving the convenience of disassembly and reducing maintenance costs. The 30mm diameter rotating dispensing end allows for dispensing in areas with large volume interference in deep cavities, making dispensing for complex deep cavity structures possible.

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0019] like Figure 1As shown, one embodiment of this utility model is: a height-adjustable and maintainable rotary dispensing structure, including a switching valve 1 and a rotary dispensing module 2, which are fixedly connected by a mounting back plate; the dispensing port of the switching valve 1 is fixedly connected to the female port of the two-way valve (the switching valve 1 controls the flow of glue, and the dispensing port is the starting point of the flow channel), the male end of the two-way valve is connected to one end of the tapered external thread of the male Luer connector (the Luer connection enables quick disassembly and assembly, reliable sealing, and easy maintenance), and the other end of the male Luer connector is connected to the rotary dispensing module 2; The rotary dispensing module 2 includes a transmission assembly, a rotating lower end cover 3, an upper straight-through lock nut connector 4, a lower straight-through lock nut connector 4, a vertical fixing rod 5, a material tube 7, and an inclined flow channel block 8. The transmission assembly drives the male Luer connector to rotate. The other end of the male Luer connector is connected to one end of the upper straight-through lock nut connector 4 (the other end of the metal male Luer connector (usually an external thread or quick-connect interface) is connected to one end of the upper straight-through lock nut connector 4 to achieve flow channel transition; the metal connector has high strength to ensure no leakage during long-term use). The other end of the upper male Luer connector is crimped to one end of the material tube 7 by a locking nut (achieving a sealed pipeline connection; the material tube is a flexible or rigid conduit to guide the glue downward). The other end of the material tube 7 is connected to the lower... One end of the straight-through lock nut connector 9 is connected by a lock nut (ensuring continuous flow path; the lower connector connects to the inclined flow path block and enters the rotating module); the other end of the lower straight-through lock nut connector 9 is fixed to one end of the inclined flow path block 8 (the inclined design facilitates the glue to turn and enter the rotating shaft), and the other end of the inclined flow path block 8 is connected to the rotating lower end cover 3 (the outlet of the inclined flow path block communicates with the internal flow path of the rotating lower end cover 3, through which the glue enters the rotating transmission part; the rotating lower end cover 3 is the input end of the rotating power and has a central through hole inside); the vertical fixing rod is locked to the rotating lower end cover 3 by screws (the vertical fixing rod is locked to the rotating lower end cover 3 by screws, rotates synchronously and transmits power; the vertical fixing rod also serves as a structural support and a rotating shaft).

[0020] It should be noted that: Switch valve 1 is used to control the flow of fluid. Rotary dispensing module 2 is used to perform the rotary dispensing action; A mounting backplate is used to secure the switching valve 1 and the rotary dispensing module 2. The switching valve 1 and the rotary dispensing module 2 are connected to form a flow channel through a plastic Luer two-way valve and a metal male Luer connector.

[0021] Example 2: A height-adjustable and maintainable rotary dispensing structure also includes a vertical sleeve 6, which is fixed to the mounting back plate. The lower end of the vertical fixing rod 5 is inserted into the vertical sleeve 6. A locking hole is provided on the side wall of the vertical sleeve 6, and the set screw passes through the locking hole and fits against the outer wall of the vertical fixing rod 5. It should be noted that: the lower end of the vertical fixing rod 5 is inserted into the vertical sleeve 6 and locked by the set screw to achieve height adjustment and fixation; after height adjustment, it is locked to ensure structural stability; the vertical sleeve 6 is fixed to the mounting back plate and serves as the external support structure for the entire rotating dispensing module 2.

[0022] Further: Replaceable flow channel: Starting from the plastic Luer two-way valve, through the metal male Luer connector, upper / lower straight lock nut connector, material pipe, inclined flow channel block to the rotating lower end cover 3, the flow channel section constitutes a "one-time replaceable flow channel structure", which can be replaced as a whole or in sections during maintenance.

[0023] Further: Height adjustment mechanism: By adjusting the insertion depth of the vertical fixing rod 5 in the vertical sleeve 6, the vertical position of the rotating dispensing module 2 is changed, achieving height adaptation within the range of 160–190mm. The overall adjustable height range of the rotating dispensing structure is 160–190mm, which is suitable for deep cavity dispensing operations to adapt to battery module cavities of different depths.

[0024] The specific process of height adjustment: Step 1: Loosen the set screw: Use an Allen wrench to rotate the set screw counterclockwise so that its end comes out of the inner wall of the vertical sleeve 6; When the set screw is completely disengaged from the vertical fixing rod 5, the vertical fixing rod 5 can slide freely up and down inside the vertical sleeve 6.

[0025] Step 2: Adjust the height: Manually or with the aid of a clamp, move the vertical fixing rod 5 (together with the rotating dispensing module 2 connected thereto) up or down. Adjust the vertical fixing rod to the target position according to the actual dispensing requirements (such as cavity depth of 160mm or 190mm).

[0026] Step 3: Lock and secure: After adjustment, use an Allen wrench to tighten the set screw clockwise; The end of the set screw presses against the outer surface of the vertical fixing rod 5, generating friction and preventing them from sliding relative to each other; Achieve reliable fixation of the height position.

[0027] Further: Modular connection: All fluid connections use a combination of Luer connectors and lock nuts, which is easy to install and remove, and can quickly replace blocked flow channels without tools.

[0028] Example 3: The parts of the flow channel that are prone to blockage (such as the inclined flow channel block and connecting pipes) are designed as disposable and replaceable structures, made of PU or Teflon material, which users can cut themselves according to the actual dispensing height.

[0029] During maintenance, only the Luer connector needs to be disassembled and the blocked pipe replaced; no professional cleaning or factory repair is required.

[0030] Implementation: 4: The diameter of the rotating dispensing tip is 30mm, which allows for flexible operation inside deep cavities with large volume structures that may interfere, ensuring a uniform and continuous adhesive line.

[0031] It should be noted that the above-mentioned technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this utility model specification; and, for those skilled in the art, improvements or modifications can be made based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims of this utility model.
