Description

Technical Field

[0001] This invention relates to the field of liquid storage device processing equipment, and in particular to an end pipe assembly device for processing air conditioning liquid storage devices. Background Technology

[0002] Liquid receivers are important components in air conditioning systems. During the production process, bends and straight pipes are typically assembled at both ends of the receiver body to form a complete piping connection structure. In existing technologies, bends and straight pipes are mostly assembled manually or semi-automatically. Operators need to first remove the bends or straight pipes, then adjust the direction of the pipe fittings, and then press them into the installation port of the liquid receiver.

[0003] However, due to the curved structure of the bends, their spatial orientation is difficult to standardize, leading to inconsistent orientations during assembly. This necessitates repeated manual adjustments, resulting in low assembly efficiency. Furthermore, inaccurate positioning during the pressing of bends and straight pipes can cause assembly misalignment or incomplete pressing, affecting the assembly quality of the liquid reservoir. In addition, most existing assembly equipment is designed for assembling single pipe components, making it impossible to automatically feed and press bends and straight pipes on the same machine, resulting in low automation and difficulty in increasing production cycle time.

[0004] In summary, existing equipment for assembling end pipes for air conditioning liquid receivers suffers from low automation, resulting in low assembly efficiency and low assembly quality. Summary of the Invention

[0025] The present invention has the following beneficial effects:

[0026] This invention discloses an end-pipe assembly device for processing air conditioning liquid receivers. The device incorporates a limiting and directional structure and a first gripper with a rotary drive within a pipe bending assembly unit. After gripping the pipe, the first gripper rotates the pipe under the drive of the rotary drive, causing the bent section to enter the arc-shaped groove of the arc-shaped limiting seat. A lateral guide limiting block limits the position of the pipe's end. When the pipe rotates to a preset direction, one end abuts against the lateral guide limiting block, thus automatically orienting the pipe's mounting port and ensuring consistent assembly direction. This structure allows for automatic adjustment of the pipe's posture during the loading process, avoiding repeated manual adjustments and improving assembly efficiency.

[0027] This invention discloses an end-pipe assembly device for processing air conditioner liquid receivers. Stable positioning is achieved through a liquid receiver positioning structure, a first fixing structure, and a second fixing structure. The liquid receiver positioning structure provides axial and radial support for the liquid receiver via a support base. At the pressing station, the liquid receiver is pressed downwards by a first pressing and fixing component and a second pressing and fixing component, ensuring stability during the pressing process. Simultaneously, a fixing rod in the first fixing structure can be inserted into the inner cavity of a bent pipe, keeping the bent pipe coaxial with the fixing structure. A second fixing plate restricts the circumferential rotation of the bent pipe, and then a first pushing mechanism pushes the bent pipe towards the liquid receiver to complete the pressing. Straight pipes are positioned by the second fixing structure and pressed by the second pushing mechanism. This structural cooperation effectively ensures the coaxiality between the pipe fitting and the liquid receiver mounting port, thereby improving pressing accuracy and assembly quality.

[0028] This invention discloses an end-pipe assembly device for processing air conditioner liquid receivers. It integrates a bending pipe assembly unit, a straight pipe assembly unit, and a liquid receiver positioning structure on the same frame, and achieves automatic transfer between multiple processing stations through a transfer mechanism. Specifically, a lifting cylinder drives a lifting block to lift the liquid receiver, and a horizontal driving cylinder drives a lifting slider to move along a guide slider, synchronously transferring the liquid receiver from one processing station to the next, thus enabling continuous multi-station processing. Simultaneously, the bending pipe and straight pipe are automatically gripped and pressed by the bending pipe assembly unit and straight pipe assembly unit, respectively, thereby achieving automatic assembly of the pipes at both ends of the liquid receiver on the same equipment, improving the automation level of the equipment and increasing production cycle time.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example:

[0039] Reference Figures 1 to 6The present invention provides a conduit feeding device, comprising: a frame, a reservoir positioning structure 1, a bent pipe assembly unit 2, and a straight pipe assembly unit 3. The reservoir positioning structure 1 is used for axial and radial positioning of the reservoir 700. The bent pipe assembly unit 2 and the straight pipe assembly unit 3 are used to press the bent pipe 800 and the straight pipe 900 to both ends of the reservoir 700, respectively. The bent pipe assembly unit 2 includes a bent pipe feeding structure 21, a first gripper 22, a limiting and oriented structure 23, a first fixing structure 24, and a first pushing mechanism 25. The first gripper 22 is used to grip the bent pipe 800 from the bent pipe feeding structure 21 and move the bent pipe 800 to the limiting and oriented structure 23. The limiting and oriented structure 23 is used to restrict the bent pipe 800. The position of the bending section is adjusted and the posture of the bend 800 is adjusted to ensure that the assembly direction of the bend 800 is consistent. The first fixing structure 24 is used to clamp and position the bend 800. The first pushing mechanism 25 drives the first fixing structure 24 to move towards the liquid reservoir 700 and press the bend 800 onto one end of the liquid reservoir 700. The straight pipe assembly unit 3 includes a straight pipe feeding structure 31, a second gripper 32, a second fixing structure 33 and a second pushing mechanism 34. The second gripper 32 is used to grip the straight pipe 900 on the straight pipe feeding structure 31 and move it to the second fixing structure 33. The second pushing mechanism 34 drives the second fixing structure 33 to move and press the straight pipe 900 onto the other end of the liquid reservoir 700.

[0040] In operation, the conduit feeding device of the present invention first places the liquid reservoir 700 on the liquid reservoir positioning structure 1. The liquid reservoir positioning structure 1 positions the liquid reservoir 700 axially and radially, ensuring a stable position during assembly. Then, the straight pipe assembly unit 3 begins operation. The straight pipe feeding structure 31 feeds the straight pipe 900, and the second gripper 32 picks up the straight pipe 900 from the straight pipe feeding structure 31 and moves it to the second fixing structure 33 for positioning and clamping. Subsequently, the second pushing mechanism 34 drives the second fixing structure 33 to move towards the liquid reservoir 700, aligning and pressing the other end of the straight pipe 900 with the liquid reservoir 700, thus completing the assembly of the straight pipe 900 and the liquid reservoir 700. After the straight pipe 900 is assembled, the bending pipe assembly unit 2 begins operation. The bending pipe feeding structure 21 feeds the bending pipe 800, and the first gripper 22 picks up the bending pipe 800 from the bending pipe feeding structure 21 and moves it to the limiting and oriented structure 23. Under the action of the limiting and oriented structure 23, the bending section of the bending pipe 800 is limited and its spatial posture is adjusted to ensure that the assembly direction of the bending pipe 800 remains consistent. After the posture adjustment is completed, the bending pipe 800 is transferred to the first fixed structure 24 for clamping and positioning. Subsequently, the first pushing mechanism 25 drives the first fixed structure 24 to move towards the liquid reservoir 700, aligning the end of the bending pipe 800 with the end of the liquid reservoir 700 and pressing it onto one end of the liquid reservoir 700, thereby completing the assembly of the bending pipe 800. Through the above structural cooperation, the bending pipe 800 and the straight pipe 900 are automatically fed and pressed onto the same equipment, thereby improving the assembly efficiency and consistency of the liquid reservoir assembly.

[0041] Furthermore, in another embodiment, such as Figure 2-3 As shown, the limiting and directional structure 23 includes an arc-shaped limiting seat 231, a lateral guide limiting block 232, and a first pushing drive member 233. The arc-shaped limiting seat 231 is provided with an arc-shaped groove that matches the curved section of the bend. The lateral guide limiting block 232 is disposed at one end of the arc-shaped groove. The first gripper 22 is connected to a rotary drive member 221. The rotary drive member 221 is used to drive the first gripper 22 to rotate the bend 800 when gripping it, so as to realize the automatic adjustment of the posture of the bend 800. When the bend 800 rotates to a preset direction, one end of it abuts against the circumferential guide block 232, thereby orienting the installation port of the bend 800 toward the liquid reservoir 700. The first pushing drive member 233 pushes the arc-shaped limiting seat 231 to move toward the first fixed structure 24.

[0042] By setting up an arc-shaped limiting seat 231 and a lateral guide limiting block 232, and cooperating with the rotation drive component 221 on the first gripper 22 to drive the bend 800 to rotate, the bending section of the bend 800 can automatically adjust its posture within the arc-shaped groove. The lateral guide limiting block 232 limits the port of the bend 800, thereby achieving automatic unification of the installation port direction of the bend 800, avoiding manual adjustment of the bend direction, and improving the assembly efficiency and consistency of the bend 800.

[0043] Furthermore, the two ends of the bent section of the bend 800 are respectively bend a port 800a and bend b port 800b; the first gripper 22 clamps the bent section of the bend 800, the bend a port 800a first contacts the arc groove, the rotary drive 221 drives the bend a port 800a to move along the arc groove toward the lateral guide limit block 232 until the bend a port 800a abuts against the lateral guide limit block 232, the bend b port 800b faces the first fixing structure 24, the first push drive 233 pushes the arc limit seat 231 to move toward the first fixing structure 24, fixing the bend b port 800b on the first fixing structure 24.

[0044] By moving the bend a port 800a along the arc groove and finally abutting against the lateral guide limit block 232, the bend b port 800b is kept facing the first fixed structure 24. The first push drive member 233 pushes the arc limit seat 231 to move towards the first fixed structure 24, so that the bend b port 800b can accurately enter the fixed position, thereby further improving the accuracy of the bend 800's posture adjustment and ensuring coaxiality in the subsequent pressing process.

[0045] Furthermore, in another embodiment, the limiting and directional structure 23 further includes a rotating pressing member 234, which is disposed above the bend 800 and cooperates with the arc-shaped limiting seat 231 to press the bend 800. It can stably press the bend 800 during the bend posture adjustment process, thereby preventing the bend 800 from jumping or deviating during the rotation adjustment process and improving the orientation stability of the bend 800.

[0046] Furthermore, in another embodiment, the first fixing structure 24 includes a fixing base 241 and a fixing rod 242. The fixing base 241 is composed of a first fixing plate 2411 and a second fixing plate 2412 arranged perpendicularly to each other. The fixing rod 242 is fixedly mounted on the first fixing plate 2411. A positioning space for accommodating the bent pipe 800 is formed between the second fixing plate 2412 and the fixing rod 242. The fixing rod 242 is coaxial with one end of the bent pipe 800 away from the lateral guide limiting block 232. The fixing rod 242 is configured such that its outer diameter is smaller than the inner diameter of the bend 800, allowing it to be inserted into the inner cavity of one end of the bend 800. When one end of the bend 800 is fitted onto the fixing rod 242, the outer wall of the bend 800 is against the second fixing plate 2412. The second fixing plate 2412 is used to restrict the circumferential rotation of the bend 800, keeping the bend 800 parallel to the second fixing plate 2412, thereby preventing the bend 800 from rotating during the pressing process and improving the pressing accuracy of the bend.

[0047] Furthermore, the bend 800b is sleeved on the outside of the fixing rod 242, and the bend 800 is parallel to the second fixing plate 2412, so that the bend 800 maintains a stable posture in the positioning state, thereby further preventing the bend 800 from rotating or shifting during the pressing process and improving the stability of the assembly of the bend 800 and the liquid reservoir 700.

[0048] Furthermore, in another embodiment, the first pushing mechanism 25 includes a curved tube pushing track 251 and a second pushing drive member 252. The first fixing structure 24 is correspondingly provided with a sliding groove. The second pushing drive member 252 can drive the first fixing structure 24 to move along the curved tube pushing track 251, which is perpendicular to the fixing rod 242. In this embodiment, the curved tube pushing track 251 is preferably slidably connected to the bottom of the second fixing plate 2412.

[0049] By setting up the bend tube push track 251 and the second push drive component 252, the first fixed structure 24 can move smoothly along the bend tube 800 push track, thereby driving the bend tube 800 to move towards the liquid reservoir 700, realizing the stable pressing of the bend tube 800, ensuring the linearity of the pressing movement, and improving the stability of the pressing process.

[0050] Furthermore, the second push drive 252 drives the first fixed structure 24 to move along the bent tube push track 251. The bent tube a port 800a is coaxial with the fixed liquid reservoir 700, and the bent tube a port 800a moves closer to the liquid reservoir 700 and is finally fixed to the inner wall of one end of the liquid reservoir 700. This ensures that the bent tube a port 800a remains coaxial with the liquid reservoir 700 during the pressing process, thereby ensuring that the bent tube can be accurately pressed to the liquid reservoir port position, avoiding pressing deviation and improving assembly quality.

[0051] Furthermore, in another embodiment, such as Figure 5-6 As shown, the liquid reservoir positioning structure 1 is used to support and position the liquid reservoir 700 during the assembly of the bent pipe 800 and the straight pipe 900, and to realize multi-station transfer. It includes multiple processing stations 11 arranged sequentially along the liquid reservoir conveying direction and a transfer mechanism 12 for driving the liquid reservoir 700 to move between the processing stations, so that the liquid reservoir 700 can complete the assembly of the bent pipe 800 and the straight pipe 900 sequentially between different stations, thereby forming a multi-station continuous processing mode, improving the production efficiency and automation level of the equipment.

[0052] Furthermore, in another embodiment, the processing station 11 includes two opposing support seats 111, which are spaced apart to form a support space for supporting the liquid reservoir 700. The support seats 111 are provided with positioning grooves to support both ends of the liquid reservoir 700, thereby further improving the stability during the assembly process.

[0053] Furthermore, in another embodiment, multiple processing stations 11 are arranged sequentially along the conveying direction, wherein at least some processing stations 11 correspond to the assembly positions of the bent pipe assembly unit 2 and the straight pipe assembly unit 3, respectively; a first pressing and fixing component 13 is provided at the processing station corresponding to the bent pipe assembly unit 2, the first pressing and fixing component 13 is used to press down the liquid reservoir 700 during the bent pipe pressing process; a second pressing and fixing component 14 is provided at the processing station corresponding to the straight pipe assembly unit 3, the second pressing and fixing component 14 is used to press down the liquid reservoir 700 during the straight pipe pressing process, thereby ensuring the stability of the bent pipe 800 and the straight pipe 900 during the assembly process.

[0054] By setting a first pressing and fixing component 13 and a second pressing and fixing component 14 at the assembly station of the bend pipe 800 and the assembly station of the straight pipe 900 respectively, the liquid reservoir 700 is pressed downward during the pressing process, thereby preventing the liquid reservoir 700 from moving or jumping during the pressing process and improving the pressing stability.

[0055] Furthermore, in another embodiment, the transfer mechanism 12 includes an elongated trough 121 extending between each processing station 11, a lifting and translating assembly 122 disposed at the bottom of the elongated trough 121, and a drive mechanism 123 for driving the lifting and translating assembly 122 to move; the elongated trough 121 passes through multiple processing stations 11 along the liquid storage tank conveying direction, and two support seats 111 of each processing station are respectively disposed on both sides of the elongated trough 121. The elongated trough 121 is provided with a plurality of grooves corresponding to the support seats 111.

[0056] In this embodiment, the transfer mechanism 12 is used to realize the automatic transfer of the liquid reservoir 700 between multiple processing stations 11. Specifically, the long trough 121 is arranged through the multiple processing stations 11 along the liquid reservoir conveying direction, and the two support seats 111 of each processing station 11 are respectively arranged on both sides of the long trough 121. When the liquid reservoir 700 is located at the processing station 11, its two ends are supported and positioned by the support seats 111; when a station switch is required, the drive mechanism 123 drives the lifting and translating component 122 to move in the long trough 121, so that the lifting and translating component 122 rises from the bottom of the long trough 121 and lifts the liquid reservoir 700 located on the support seats 111, and then drives the liquid reservoir 700 to move along the conveying direction to the next processing station 11, thereby realizing the continuous transfer of the liquid reservoir 700 between the processing stations 11. By setting a through long trough 121 between processing stations 11, the same lifting and translating component 122 can simultaneously lift and synchronously translate multiple liquid reservoirs 700, thereby improving the conveying efficiency in the multi-station assembly process.

[0057] Furthermore, in another embodiment, the lifting and translation assembly 122 includes a guide slider 1221, a lifting slider 1222, and a lifting block 1223. The guide slider 1221 is fixedly connected to the frame, and the lifting slider 1222 is slidably connected to the guide slider 1221, thereby enabling translational movement along the liquid reservoir conveying direction. The lifting block 1223 is disposed at the upper end of the lifting slider 1222, and its upper surface can lift the liquid reservoir 700 in the lifting state.

[0058] In this embodiment, the lifting and translation assembly 122 achieves the lifting and translation movement of the liquid reservoir 700 through the cooperation of the guide slider 1221, the lifting slider 1222 and the lifting support block 1223. The guide slider 1221 is fixedly mounted on the frame to guide the movement of the lifting slider 1222. The lifting slider 1222 is slidably connected to the guide slider 1221, so that it can reciprocate and translate along the liquid storage container conveying direction under the action of the drive mechanism. The lifting block 1223 is set at the upper end of the lifting slider 1222. When the lifting block 1223 rises, its upper surface can lift the liquid storage container 700 located on the support seat 111, so that the liquid storage container 700 is separated from the support seat 111. Then, the lifting slider 1222 moves along the conveying direction under the guidance of the guide slider 1221, thereby driving the liquid storage container 700 to move to the next processing station. After the translation is completed, the lifting block 1223 descends, so that the liquid storage container 700 falls back onto the support seat 111 of the corresponding processing station 11, achieving stable positioning.

[0059] Furthermore, in another embodiment, the drive mechanism 123 includes a lifting cylinder 1231 and a horizontal drive cylinder 1232. The lifting cylinder 1231 is used to drive the lifting block 1223 to rise or fall in the vertical direction, thereby lifting or releasing the liquid reservoir 700. The horizontal drive cylinder 1232 is connected to the lifting slider 1222 and is used to drive the lifting slider 1222 to move along the guide slider 1221 in the conveying direction.

[0060] By setting up a first robotic arm 4 for feeding bent and straight pipes, and a second robotic arm 5 for handling the processed liquid storage tank, the feeding of pipe fittings and the unloading of products can be completed automatically, thereby further reducing manual operation and improving the automation level and production efficiency of the entire production line.

[0061] Furthermore, in another embodiment, the device further includes a first robotic arm 4 for feeding the bent pipe 800 and the straight pipe 900, and a second robotic arm 5 for handling the processed liquid reservoir 700.

[0062] Furthermore, in another embodiment, the device further includes a pipe bending and turning mechanism 15, which is located at the last processing station after the pipe bending 800 and the straight pipe 900 are press-fitted to both ends of the reservoir 700. The pipe bending and turning mechanism 15 is used to rotate the assembled pipe bending 800 circumferentially to unify the orientation of the pipe bending 800, so as to facilitate subsequent gripping by the robotic arm.

[0063] The pipe bending and steering mechanism 15 includes a rotating wheel 151, a rotating shaft 152, a mounting bracket 153, and a rotation drive component 154. The mounting bracket 153 is fixedly mounted on the machine frame at the last processing station. The rotating shaft 152 is rotatably mounted on the mounting bracket 153, and the rotating wheel 151 is fixedly mounted on the rotating shaft 152. The rotation drive component 154 is connected to the rotating shaft 152 and is used to drive the rotating shaft 152 to rotate the rotating wheel 151. The rotation drive component 154 is preferably a motor, a rotary cylinder, or a stepper motor.

[0064] The outer circumferential surface of the rotating wheel 151 can contact the outer wall of the assembled bent tube 800. When the reservoir 700 and its bent tube 800 are moved to the last processing station, the rotating drive 154 drives the rotating wheel 151 to rotate, thereby causing the bent tube 800 to rotate circumferentially around the axis of the reservoir 700 through the friction between the rotating wheel 151 and the bent tube 800, adjusting the mounting port of the bent tube 800 to a preset direction. After the rotation is completed, the orientation of all bent tubes 800 is consistent, which facilitates the subsequent robotic arm to clamp and transport the bent tubes 800 to the next process in a uniform posture. By setting the above-mentioned bent tube turning mechanism 15, the orientation of the bent tubes 800 can be automatically adjusted after assembly, so that the bent tubes 800 on each reservoir 700 maintain a uniform orientation, thereby improving the stability of the robotic arm's gripping and the efficiency of automated production.

[0065] Working principle: First, the liquid reservoir 700 is placed at the first processing station 11 of the liquid reservoir positioning structure 1 by an external feeding mechanism or the second robotic arm 5. The two ends of the liquid reservoir 700 are respectively attached to the positioning grooves of the two support seats 111, thereby realizing the initial axial and radial support positioning of the liquid reservoir 700. When workpieces need to be transported, the drive mechanism 123 first drives the lifting cylinder 1231 to move, causing the lifting block 1223 to lift the liquid reservoir 700 upwards, so that the liquid reservoir 700 is detached from the support seat 111; then the horizontal drive cylinder 1232 drives the lifting slider 1222 to move along the guide slider 1221 in the long groove 121 along the conveying direction, thereby driving multiple liquid reservoirs 700 to be simultaneously transported from the previous processing station 11 to the next processing station 11; after the transport is completed, the lifting cylinder 1231 retracts, and the liquid reservoir 700 falls back onto the support seat 111 of the corresponding station, realizing synchronous transport and positioning of multiple stations.

[0066] When the reservoir 700 is transferred to the processing station 11 corresponding to the straight pipe assembly unit 3, the second gripper 32 picks up the straight pipe 900 from the straight pipe feeding structure 31 and places it at the second fixing structure 33 for positioning. Subsequently, the second pushing mechanism 34 drives the second fixing structure 33 to move towards the reservoir 700, so that the straight pipe 900 is aligned with the other end of the reservoir 700 and pressed and fixed. During the pressing process of the bent pipe 800 or the straight pipe 900, the first pressing and fixing component 13 or the second pressing and fixing component 14 at the corresponding station presses down on the reservoir 700 to prevent the reservoir 700 from shifting or shaking during the pressing process, thereby ensuring assembly accuracy.

[0067] As the reservoir 700 continues to be transferred to the processing station 11 corresponding to the tube bending assembly unit 2, the first robotic arm 4 transports the tube bending 800 to the tube bending loading structure 21. Subsequently, the first gripper 22 picks up the tube bending 800 from the tube bending loading structure 21 and moves it to the limiting and oriented structure 23. During this process, the rotary drive 221 drives the first gripper 22 to rotate the tube bending 800 circumferentially, so that the bent section of the tube bending 800 enters the arc-shaped groove of the arc-shaped limiting seat 231, and moves the tube bending port a 800a along the arc-shaped groove until it abuts against the lateral guide limiting block 232, thereby completing the orientation of the tube bending 800 and making the tube bending port b 800b face the first fixed structure 24. Subsequently, the first push drive component 233 pushes the arc-shaped limiting seat 231 to move towards the first fixed structure 24, so that the bend 800b is fitted onto the outside of the fixed rod 242. At the same time, the outer wall of the bend 800 abuts against the second fixed plate 2412 to achieve circumferential limiting. If necessary, the rotating pressing component 234 presses the bend 800 downward to ensure its stable positioning. After positioning is completed, the second push drive component 252 drives the first fixed structure 24 to move along the bend push track 251 towards the reservoir 700, so that the bend 800a is coaxially aligned with the end of the reservoir 700 and gradually pressed into the inner wall of one end of the reservoir 700, thereby completing the press-fit assembly of the bend 800.

[0068] After the elbow 800 and straight pipe 900 are assembled, the reservoir 700 is moved to the last processing station, at which point the elbow turning mechanism 15 starts working. The rotating drive 154 drives the rotating shaft 152 to rotate the rotating wheel 151, so that the outer circumferential surface of the rotating wheel 151 contacts the outer wall of the elbow 800. Through friction, the elbow 800 rotates circumferentially around the axis of the reservoir 700, thereby adjusting the installation port of the elbow 800 to a preset uniform direction. After the turning is completed, all assembled elbows 800 are aligned in the same direction. Then, the second robotic arm 5 picks up the assembled reservoir 700 in a uniform posture and transports it to the next process, thereby realizing the continuous automatic assembly of the reservoir 700 with the elbow 800 and straight pipe 900.
