Description

Technical Field

[0001] The present application relates to the field of combined processing technology, and in particular to an elbow reclaiming device and a heat exchanger production line. Background Art

[0002] During the production line of air-conditioning heat exchangers (evaporators and condensers), an elbow needs to be inserted into the heat exchanger. There is a welding ring on each of the two copper tubes of the elbow. After the elbow is inserted into the copper tube of the heat exchanger, it enters the welding station, the welding ring melts, and the elbow and the copper tube of the heat exchanger are welded together to ensure the airtightness of the heat exchanger.

[0003] In the production of traditional heat exchangers, elbows are generally installed manually on the copper tubes of the heat exchanger, which is time-consuming and labor-intensive. In addition, the on-site working environment is poor, and the labor intensity of inserting elbows is high. The operator's long-term repetitive elbow insertion operation is prone to problems such as missing or incorrect elbow insertion, affecting the production efficiency and product qualification rate of the heat exchanger. Summary of the Invention

[0004] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application provides an elbow material removal device and a heat exchanger production line, which can improve the assembly efficiency of elbows and improve the production quality and production efficiency of air conditioner heat exchangers.

[0007] a material blocking mechanism, used to open or close the material outlet to correspondingly release or block the elbow; and

[0008] The material picking mechanism includes a driving member and a material picking member. The driving member can drive the material picking member to move in a direction close to the discharge port, so that the material picking member grabs the elbow of the discharge port and drives the material blocking mechanism to open the discharge port.

[0009] The elbow reclaiming device according to the first aspect of the present application has at least the following beneficial effects:

[0010] When the elbow picking device of the present application is in use, the driving member drives the picking member to move in the direction close to the discharge port of the storage channel, so that the picking member moves to the discharge port of the storage channel and grabs the elbow at the discharge port. Then, the driving member continues to drive the picking member that has grabbed the elbow to continue moving, and then drives the material blocking mechanism to open the discharge port of the storage channel, so that the picking member that has grabbed the elbow can pass through the discharge port smoothly, and then can move to the elbow assembly station under the continuous drive of the driving member. By grabbing the picking member with the elbow, the elbow can be accurately inserted into the corresponding position of the copper tube of the heat exchanger to complete the elbow insertion action. The elbow picking device of the present application has an ingenious structure. Through the coordinated arrangement of the material storage channel, the material blocking mechanism and the material picking mechanism, the picking parts of the material picking mechanism can grab the elbows one by one and accurately insert the elbows into the corresponding positions of the copper tubes of the heat exchanger. Compared with the traditional method of manually inserting elbows, it saves time and effort, effectively improves the assembly efficiency of the elbows, and thus indirectly improves the production quality and production efficiency of the air-conditioning heat exchanger.

[0011] In some embodiments, the material blocking mechanism is rotatably arranged on the base frame. When the material picking member grabs the elbow and passes through the discharge port, the elbow drives the material blocking mechanism to rotate around the base frame to open the discharge port. A first elastic reset member is also provided between the material blocking mechanism and the base frame.

[0014] In some embodiments, the stop portion is a stop plane perpendicular to the length direction of the material storage channel, and the introduction portion is an introduction slope or introduction arc surface inclined relative to the length direction of the material storage channel.

[0015] In some embodiments, there are two stoppers, which are rotatably arranged on opposite sides of the discharge port through the two linkage members.

[0016] In some embodiments, the material picking member includes two clamping arms that can move relatively far away from or close to each other, and both of the clamping arms are provided with an arc-shaped clamping cavity that is adapted to the outer wall of the elbow.

[0017] In some embodiments, the two clamping arms are driven by an opening and closing power mechanism to move relatively away from or closer to each other.

[0018] In some embodiments, the driving member is a driving cylinder.

[0019] In a second aspect, the present application provides a heat exchanger production line, which includes: the elbow material taking device described above; wherein, the material taking mechanism is provided with at least two.

[0020] The heat exchanger production line according to the second aspect of the present application has at least the following beneficial effects:

Those skilled in the art can understand the specific meanings of the above terms in the embodiments of the present application based on specific circumstances.

[0045] See also Figure 1 and Figure 2 The present application provides an elbow taking device that can be set on the production line of the air-conditioning heat exchanger, and is used to automatically take out the elbow 400 and insert and assemble it onto the copper tube of the heat exchanger.

[0046] The elbow material taking device includes a base frame 100 , a material blocking mechanism 200 and a material taking mechanism 300 .

[0047] The base frame 100 is provided with a storage channel 110 for arranging and storing a plurality of elbows 400. The storage channel 110 has a discharge port 111. The blocking mechanism 200 is used to open or close the discharge port 111 to correspondingly release or block the elbows 400 located at the discharge port 111. The picking mechanism 300 includes a driving member 310 and a picking member 320. The driving member 310 can drive the picking member 320 to move in a direction close to the discharge port 111 of the storage channel 110, so that the picking member 320 grabs the elbow 400 at the discharge port 111 and drives the blocking mechanism 200 to open the discharge port 111.

[0048] It should be noted that the storage channel 110 on the base frame 100 can be a straight channel or an arc-shaped channel, preferably a straight channel, such as a straight groove. The inner diameter width of the storage channel 110 is adapted to the width of the elbow 400 to be stored to ensure that the elbow 400 can be arranged along the trajectory of the storage channel 110 and stored in the storage channel 110, and ensure that the elbow 400 can smoothly pass through the discharge port 111.

[0049] The material storage channel 110 can be vertically arranged relative to the horizontal plane, or can be horizontally or inclined relative to the horizontal plane, and there is no specific limitation.

[0050] In order to facilitate the description of the embodiments of the present application and simplify the description, the present application describes the embodiment with the storage channel 110 vertically or inclined relative to the horizontal plane, and the storage channel 110 as a straight channel. At the same time, the length direction of the storage channel 110 is used as the up and down direction, and the discharge port 111 of the storage channel 110 is set at the lower end of the storage channel 110.

[0051] See also Figure 2 When the elbow picking device of the present application is used on a heat exchanger production line, a loading port can be opened at one end of the storage channel 110 away from the discharge port 111. The loading port is connected to a corresponding vibration plate on which a plurality of elbows 400 to be inserted are stored. The storage channel 110 is vertically or inclined relative to the vibration plate. In this way, the vibration plate can discharge the elbows 400 to be inserted into the storage channel 110 one by one through the above-mentioned loading port by vibration, thereby completing the loading of batches of elbows 400.

[0052] In addition, when the elbow retrieving device of the present application is used in a heat exchanger production line, the driving member 310 of the retrieving mechanism 300 is preferably a driving cylinder. Of course, the driving member 310 can also be other driving devices, and there is no specific limitation. The driving member 310 can be a functional structure that can drive the retrieving member 320 to move in a direction close to or away from the discharge port 111 of the storage channel 110. The retrieving member 320 of the retrieving mechanism 300 is preferably a cylinder clamp to achieve fixed grasping or release of the elbow 400.

[0053] The entire retrieving mechanism 300 can be connected to a corresponding robot on the production line, so that the robot can control the overall movement of the retrieving mechanism 300. After the retrieving member 320 that has grasped the elbow 400 passes through the discharge port 111, the robot can drive the entire retrieving mechanism 300 to the corresponding elbow assembly station. The driving member 310 on the retrieving mechanism 300 can continue to drive the retrieving member 320 with the elbow 400 in linear motion, so that the retrieving member 320 can linearly insert the elbow 400 into the insertion position of the heat exchanger copper tube, completing the insertion of the elbow 400.

[0054] See also Figure 2 When the elbow pick-up device of the present application is in use, the blocking mechanism 200 is in the initial state of closing the discharge port 111. At this time, the elbow 400 located at the discharge port 111 is stopped by the blocking mechanism 200. Then, the driving member 310 drives the pick-up member 320 to move in a direction close to the discharge port 111, so that the pick-up member 320 moves to the outlet 111 of the storage channel 110 and grabs the elbow 400 located at the outlet 111. Then, the driving part 310 continues to drive the material picking part 320 that has grasped the elbow 400 to continue moving, and then drives the material blocking mechanism 200 to open the discharge port 111 of the material storage channel 110, so that the material picking part 320 that has grasped the elbow 400 can smoothly pass through the discharge port 111, and then can move to the elbow assembly station under the continuous drive of the driving part 310. The material picking part 320 that grasps the elbow 400 can accurately insert the elbow into the corresponding position of the copper tube of the heat exchanger, completing the elbow 400 insertion action.

[0055] It should be noted that in the above process, when the material picking piece 320 that grabs the elbow 400 passes through the discharge port 111, the elbow 400 arranged in the storage channel 110 will slide forward in the direction close to the discharge port 111 due to its own gravity by a distance of one elbow 400, and the elbow 400 located at the lower end moves to the position of the discharge port 111. At this time, the material blocking mechanism 200 can automatically reset to close the discharge port 111, thereby stopping the elbow 400 located here, preventing the elbow 400 from continuing to move and slide, so as to facilitate the next material picking by the material picking mechanism 300.

[0056] When the elbow picking device of the present application is applied to a heat exchanger production line, more than two picking mechanisms 300 can be arranged. Multiple picking mechanisms 300 alternately perform picking and feeding actions to ensure the continuity of elbow assembly and further improve the assembly efficiency of the elbow and heat exchanger.

[0057] It is not difficult to understand that the elbow picking device of the present application has an ingenious structure. Through the coordinated arrangement of the material storage channel 110, the material blocking mechanism 200 and the picking mechanism 300, the picking part 320 of the picking mechanism 300 can grab the elbows 400 one by one and accurately insert the elbows 400 into the corresponding positions of the copper tubes of the heat exchanger. Compared with the traditional method of manually inserting elbows, it saves time and labor, effectively improves the assembly efficiency of the elbows 400, and thus indirectly improves the production quality and production efficiency of the air-conditioning heat exchanger.

[0058] See also Figure 2 and Figure 3 In some embodiments of the present application, the material blocking mechanism 200 is rotatably arranged on the base frame 100. When the material picking member 320 grabs the elbow 400 and passes through the discharge port 111, the elbow 400 drives the material blocking mechanism 200 to rotate around the base frame 100 to open the discharge port 111. A first elastic reset member 500 is also provided between the material blocking mechanism 200 and the base frame 100.

[0059] Specifically, the material blocking mechanism 200 can be a blocking block, the upper portion of which is hinged to the base frame 100 via a rotating shaft, and the lower portion of which is preferably a blocking slope or a blocking arc surface, which facilitates the conversion of the linear motion of the material picking member 320 into the rotational motion of the material blocking mechanism 200. When the material blocking mechanism 200 is in a state of closing the discharge port 111, the elbow 400 at the lowest end of the material storage channel 110 is at the discharge port 111, and the straight sections at both ends of the elbow 400 abut against the lower portion of the blocking block. When the material picking member 320, which has grasped the elbow 400, continues to move through the discharge port 111, the elbow 400 on the material picking member 320 drives the blocking block to rotate around the connection point with the base frame 100, thereby opening the discharge port 111.

[0060] In addition, the first elastic reset member 500 arranged between the material blocking mechanism 200 and the base frame 100 is preferably a torsion spring, so that after the material picking member 320 with the elbow 400 is grasped and passes through the discharge port 111, the material blocking mechanism 200 can be elastically reset, and then the elbow 400 located at the discharge port 111 is stopped, thereby ensuring the continuity of the movement of the material picking mechanism 200, and also providing corresponding convenience for multiple material picking mechanisms 200 to alternately pick up materials.

[0061] In the present application, the material blocking mechanism 200 is rotated and arranged on the base frame 100, so that the material picking piece 320 that grabs the elbow 400 at the discharge port 111 can simultaneously open the discharge port 111 during the process of passing through the discharge port 111, thereby driving the elbow 400 to separate from the material storage channel 110, and the discharge port 111 can be synchronously opened through the self-displacement movement of the material picking piece 320.

[0062] At the same time, by setting a first elastic reset member 500 between the material blocking mechanism 200 and the base frame 100, it is ensured that the material blocking mechanism 200 can automatically reset to the state of closing the material outlet 111 after opening the material outlet 111 to release a single elbow 400, and ensure that the material picking member 320 grabs the elbows 400 one by one in an orderly manner and passes through the material outlet 111, thereby completing the material picking and feeding actions of the elbows 400 one by one, without the need to additionally set up a driving device that separately drives the material blocking mechanism 200 to rotate, saving corresponding costs and processes, improving the action continuity of the material picking mechanism 300, and thereby improving the material picking, feeding and subsequent assembly efficiency of the elbow 400.

[0063] See also Figure 3 and Figure 4 In some embodiments of the present application, the material blocking mechanism 200 includes a stop member 210 for stopping or releasing the elbow 400 and a linkage member 220 rotatably connected to the stop member 210. The linkage member 220 is also rotatably connected to the base frame 100. A second elastic reset member 230 is provided between the stop member 210 and the linkage member 220.

[0064] Specifically, the linkage member 220 is a linkage rod, and the upper end of the linkage member 220 is rotatably connected to the base frame 100 through the first rotating shaft 240; the first elastic return member 500 is a torsion spring, and the first elastic return member 500 is arranged between the base frame 100 and the linkage member 220; the stop member 210 is a stop block, and the stop member 210 is rotatably connected to the linkage member 220 through the second rotating shaft 250; similarly, the second elastic return member 230 is a torsion spring.

[0065] See in turn Figure 5 、 Figure 6 、 Figure 7 and Figure 8 It is not difficult to understand that when the material picking piece 320 that grabs the elbow 400 at the discharge port 111 continues to pass through the discharge port 111 under the drive of the driving piece 310, the elbow 400 on the material picking piece 320 will drive the stopper 210 in contact with it to rotate around the connection point with the linkage piece 220 due to its own linear motion, thereby causing the stopper 210 to rotate to open the discharge port 111, thereby allowing the material picking piece 320 to pass through. In the above process, since the linkage 220 is rotatably connected to the stop member 210, the linkage 220 will rotate around the connection point with the base frame 100 under the rotation action of the stop member 210, thereby increasing the rotation angle of the stop member 210, so that the material picking member 320 can pass through the discharge port 111 in a short time, and then the linkage 220 and the stop member 210 are respectively reset to the initial position under the elastic action of the first elastic reset member 500 and the second elastic reset member 230, so that the stop member 210 can quickly stop the elbow 400 located at the discharge port 111 at this time.

[0066] It should be understood that by configuring the material blocking mechanism 200 to be a stopper 210 and a linkage 220 that cooperate with each other, it is ensured that the stopper 210 can be synchronously driven by the elbow 400 when the material picking member 320 drives the elbow 400 through the discharge port 111, and then rotates to open the discharge port 111. The ingenious setting of the linkage 220 also ensures that the stopper 210 has a more flexible degree of freedom of movement, effectively increasing the rotation angle of the stopper 210, so that the material picking member 320 with the elbow 400 can quickly pass through the discharge port 111, and the stopper 210 can quickly reset to the state of closing the discharge port 111, thereby preventing the remaining elbows 400 arranged in the storage channel 110 from falling from the storage channel 110 without restriction, affecting the continuity of the elbow picking and feeding actions of the elbow picking device of this application for multiple elbows 400.

[0067] That is, through the above-mentioned setting, during the short material picking cycle of the material picking part 320 for a single elbow 400, the material blocking mechanism 200 can synchronously and quickly complete the action of opening and closing the material outlet 111, and stably stop or release the elbows 400 in the material storage channel 110 one by one. At the same time, it also realizes the accurate control of the material unloading time of each elbow 400, ensuring the continuity of the overall material picking and feeding action of the material picking part 320 and the material picking mechanism 300, thereby improving the assembly efficiency of the elbow 400 and the production efficiency of the heat exchanger.

[0068] In addition, the elbow picking device of the present application can also deliver batches of elbows 400 to the storage channel 110 through the picking mechanism 300 through the above-mentioned setting, thereby realizing the function of loading batches of elbows 400. That is, when the storage channel 110 is empty or there are only a few elbows 400 left, the robot on the production line can drive the picking mechanism 300 as a whole to the position of the material tray where batches of elbows 400 are stored on the production line, so that the picking member 320 on the picking mechanism 300 moves to and grabs a single elbow 400 under the action of the driving member 310, and then moves to the position below the discharge port 110 under the drive of the robot. At this time, the picking member 320 that has grabbed the elbow 400 continues to move in the direction close to the discharge port 110 under the driving action of the driving member 310, so that The elbow 400 on the material picking piece 320 contacts the stop piece 210 on the material blocking mechanism 200, thereby driving the stop piece 210 and the linkage piece 220 to rotate, and then opening the discharge port 110 for the material picking piece 320 with the elbow 400 to pass through and enter the material storage channel 110, and then, the corresponding stop piece 210 and the linkage piece 220 elastically reset to close the discharge port 110, at this time, the material picking piece 320 can release the elbow 400 thereon, so that the bottom of the elbow 400 abuts against the stop piece 210, completing the loading of the elbow 400.

[0069] In this way, by repeating the above-mentioned actions, batches of elbows 400 can be pushed and loaded into the storage channel 110. It is understandable that the present application can also arrange multiple material-retrieving mechanisms 300 to work alternately, and according to actual assembly requirements, realize the material-retrieving, feeding and loading actions of multiple elbows 400, ensure the continuity of the assembly of the elbows 400, improve the degree of automation, greatly improve the assembly efficiency of the elbows 400, and improve the production quality and production efficiency of the heat exchanger.

[0070] See also Figure 3 and Figure 4 In some embodiments of the present application, the end of the stopper 210 close to the storage channel 110 is provided with a stop portion 211 that cooperates with the bottom stop of the elbow 400, and the end of the stopper 210 away from the storage channel 110 is provided with an introduction portion 212 for slidingly cooperating with the outer wall of the elbow 400.

[0071] It can be understood that the stopper portion 211 and the introduction portion 212 are respectively provided at the upper and lower ends of the stopper 210. Figure 4 and Figure 5 When the material blocking mechanism 200 is in the initial state of closing the discharge port 110, the elbow 400 at the discharge port 110 abuts against the stop portion 211 to be stopped by the stop portion 211; when the material picking mechanism 300 loads the grabbed elbow 400 into the storage channel 110, the material picking member 320 moves from bottom to top, and the upper end of the elbow 400 contacts the introduction portion 212 first. The material picking member 320 combines its own linear motion and the introduction effect of the introduction portion 212 to drive the stop portion 210 to rotate and open, while also synchronously introducing the elbow 400 thereon into the storage channel 110. After the stop portion 211 is elastically reset, the material picking member 320 releases the elbow 400 to complete the loading.

[0072] The present application provides a stopper 211 and an introduction portion 212 at the upper and lower ends of the stopper 210, respectively. The stopper 211 effectively ensures that the stopper 210 stops or releases the elbow 400, and the introduction portion 212 serves to slide the elbow 400 in the reverse direction into the material storage channel 110, thereby ensuring that the material-taking mechanism 300 smoothly delivers the elbow 400 in the reverse direction into the material storage channel 110, thereby ensuring the stability of the elbow 400 in discharging or reloading.

[0073] See also Figure 4 and Figure 5 In some embodiments of the present application, the stop portion 211 is a stop plane perpendicular to the length direction of the storage channel 110, and the introduction portion 212 is an introduction slope or introduction arc surface inclined relative to the length direction of the storage channel 110.

[0074] Specifically, the material storage channel 110 is a straight channel, the stop plane is a horizontal plane perpendicular to the central axis of the material storage channel 110 , and the inlet slope or inlet arc surface is inclined to the central axis of the material storage channel 110 .

[0075] By setting the stop portion 211 as a stop plane perpendicular to the length direction of the storage channel 110, the present application can make the bottom end of the elbow 400 at the discharge port 111 horizontally abut against the stop portion 211, thereby preventing the elbow 400 from tilting or misaligned relative to the discharge port 111. At the same time, the stability of the elbow queue stored in the storage channel 110 is ensured, thereby ensuring that the material-taking mechanism 300 can stably and orderly take out and feed the elbows in the storage channel 110 one by one.

[0076] The present application sets the introduction part 212 as an introduction slope or an introduction arc surface, so that the introduction part 212 can better adapt to the curved shape of the upper part of the elbow 400, ensuring that the material-picking mechanism 300 slides the elbow 400 from bottom to top into the storage channel while reducing the contact area between the introduction part 212 and the elbow 400, thereby avoiding the elbow 400 being rigidly squeezed and deformed by the stopper 210 during the process of passing through the discharge port 111 and loading into the storage channel 110, thereby affecting the structural quality of the elbow 400.

[0077] See also Figure 4 and Figure 5 In some embodiments of the present application, there are two stoppers 210 , which are rotatably disposed on opposite sides of the discharge port 111 through two linkage members 220 .

[0078] It can be understood that, through the above-mentioned arrangement, a single stop member 210 and a single linkage member 220 are used in pairs to form a material blocking mechanism 200, so that there are material blocking mechanisms 200 on both sides of the discharge port 111. The two relative material blocking mechanisms 200 work together to stably close or open the discharge port 111, thereby improving the stability of the stopping or releasing action of the elbow 400 at the discharge port 111, and further ensuring that the material picking mechanism 300 can stably and effectively pick up, feed or load the elbow 400 one by one.

[0079] See also Figure 9 、 Figure 10 and Figure 11 In some embodiments of the present application, the material picking member 320 includes two clamping arms 321 that can be relatively far away from or close to each other, and both clamping arms 321 are provided with an arc-shaped clamping cavity 322 that is adapted to the outer wall of the elbow 400.

[0080] Specifically, the two clamping arms 321 are driven to move relatively farther apart or closer together by an opening and closing power mechanism 323. The opening and closing power mechanism 323 can be a conventional opening and closing cylinder, and the two air claws of the opening and closing cylinder are respectively connected to the two clamping arms 321, thereby controlling the two clamping arms 321 to move relatively closer or farther apart, thereby achieving the grasping or releasing of the elbow 400.

[0081] In addition, see Figure 11 and Figure 12 The present application provides an arc-shaped clamping cavity 322 on the clamping arm 321 to adapt well to the arc shape of the outer wall of the elbow 400. In this way, when the two clamping arms 321 approach each other to grab the elbow 400, the arc-shaped clamping cavities 322 of the two clamping arms 321 are slid onto the front and rear outer walls of the elbow 400 respectively, so that the outer wall of the elbow 400 is accommodated in the arc-shaped clamping cavity 322 and remains stably clamped by the two arc-shaped clamping cavities 322, ensuring that the clamping force on the outer wall of the elbow 400 is uniform, avoiding point contact or local surface contact between the clamping arm 321 and the elbow 400, and causing the contact part of the elbow 400 and the clamping arm 321 to be deformed due to excessive force.

[0082] Obviously, by setting an arc-shaped clamping cavity 322 on the clamping arm 321, not only can the material picking part 320 ensure the stable clamping or release function of the elbow 400, but it can also effectively adapt to the outer wall contour shape of the elbow 400, ensuring the force stability and structural stability of the elbow 400, and indirectly improving the assembly quality of the elbow and the production quality of the heat exchanger.

[0083] In addition, the present application also provides a heat exchanger production line, which includes the above-mentioned elbow material taking device, wherein at least two material taking mechanisms 300 are provided.

[0084] It should be noted that the heat exchanger production line of the present application can be equipped with a corresponding plurality of manipulators, each of which controls the overall movement of the corresponding material-picking mechanism 300, so that the material-picking mechanism 300 can reciprocate between the material-picking station of the discharge port 111 of the storage channel 110 and the elbow assembly station of the heat exchanger.

[0085] Obviously, the heat exchanger production line of the present application, since it is equipped with the above-mentioned elbow material taking device, also has the same technical effect as the above-mentioned elbow material taking device, that is, it can effectively improve the assembly efficiency of the elbow 400 and effectively improve the production quality and production efficiency of the air-conditioning heat exchanger.

[0086] At the same time, the heat exchanger production line of the present application, by setting up multiple material-taking mechanisms 300, can enable multiple material-taking mechanisms 300 to perform material-taking and feeding operations alternately and continuously, thereby ensuring the continuity of elbow assembly and further improving the assembly efficiency of the elbow and the production efficiency of the heat exchanger.
